Description:Field of the invention

[0001] The present invention relates to a vehicle interior. More specifically, the present invention relates to an air vent assembly for a vehicle interior.

Background of the invention:

[0002] Presently, conventional vehicle air vent assemblies have encountered challenges related to several key aspects, including limited airflow control, reduced adaptability to varying user preferences and environmental conditions, and a lack of customizable features. These limitations often result in suboptimal user experiences, as occupants may struggle to achieve the desired comfort levels within the vehicle cabin. Furthermore, the aesthetic design of these conventional assemblies may not align with the evolving expectations of consumers who increasingly prioritize both functionality and visual appeal in modern vehicles.

[0003] The first challenge faced by conventional air vent assemblies is related to airflow control. Standard systems typically offer limited adjustability in directing and regulating the airflow within the vehicle cabin. This limitation can result in uneven distribution of air, leading to discomfort for passengers in certain areas of the vehicle. Additionally, conventional vents may not provide users with sufficient control over the intensity of airflow, making it challenging to tailor the climate conditions to individual preferences.

[0004] Existing technologies have simple mechanical mechanisms to control the direction and volume of airflow. Commonly, a single lever or knob is responsible for adjusting the orientation of the air-directive vanes, controlling the direction of the airflow. Another mechanism, probably a separate mechanism, is used to regulate the volume of the airflow through the air ducts. However, such systems had inherent limitations in terms of user-friendliness, precision, and adaptability to diverse user preferences.

[0005] Further, the drawback of existing air vent assemblies is the need for multiple controls to manage different aspects of airflow, leading to a cluttered and less intuitive interface. Users often had to manipulate various controls independently, making the process less ergonomic and potentially distracting while driving. Additionally, the lack of integration between different control elements could result in a less responsive and less customizable experience for the occupants.

[0006] Therefore, there is a requirement for an air vent assembly (100) for a vehicle interior to overcome all or a few drawbacks of the present technologies.

Objects of the invention
[0007] An object of the present invention is to provide an air vent assembly for a vehicle interior.

[0008] Another object of the present invention is to provide an air vent assembly for a vehicle interior which is operated using a single operating member.

[0009] Yet another object of the present invention is to provide an air vent assembly for a vehicle interior that is adapted to hide the operating mechanism to make the air vent aesthetically appealing.

[0010] One more object of the present invention is to provide an air vent assembly for a vehicle interior that is adapted to distribute and direct the air evenly throughout the vehicle interior.

Summary of the invention:

[0011] According to the present invention, there is provided with an air vent assembly for a vehicle interior.

[0012] An air vent assembly for the vehicle interior includes an outer housing and an inner housing configuring a first air duct and a second air duct, an operating member operably connected with the inner housing, a set of air-directive vanes to control the airflow towards the vehicle interior in a sideways direction, a directivity flap to control the direction of the air flowing in the first air duct or the second air duct, a shutoff flap to control the volume of the air flowing towards the first air duct and the second air duct, a transmission assembly arranged between the operating member and the shutoff flap, facilitating transmission of operating member movement to both the directivity flap and the shutoff flap. The first air duct and the second air duct are adapted to carry airflow towards the interior of the vehicle from an inlet opening.

[0013] The operating member is connected to the inner housing using a spherical joint. The operating member is connected to the inner housing in such a way that one end of the operating member is visible to the user and has a knob to operate the operating member, wherein the other end of the operating member is enclosed within the inner housing to make it invisible to the user.

[0014] Further, the set of air-directive vanes are connected to a link bar and the link bar is connected to a portion of the operating member. the link bar is movable in a translatory movement to pivot the set of air-directive vanes around a first axis upon operating the operating member in a horizontal angular motion.

[0015] Furthermore, the transmission assembly includes a telescopic lever connected to a distal end of the operating member, a shaft connected to a portion of the telescopic lever, and a gear arranged on a distal end portion of the shaft and operably engaged with the shutoff flap. The shaft has a cavity to receive the telescopic lever. The gear is adapted to rotate along the rotational motion of the shaft thereby controlling the movement of the shutoff flap.

[0016] The telescopic lever includes a cylinder and a sliding element slidably arranged within the cylinder. The sliding element is adapted to connect with the end of the operating member forming a first joint, and the cylinder has a cylinder head that is adapted to connect with the shaft forming a second joint. Specifically, the second joint is adapted to transmit the rotational motion of the telescopic lever to the shaft thereby controlling the movement of the shutoff flap.
[0017] Furthermore, the directivity flap is operably connected to a telescopic lever of the transmission assembly through a connecting element. The connecting element is fixedly connected to the directivity flap and has an elongated slot to receive a telescopic lever therein. The elongated slot provides free movement of the telescopic lever in a horizontal and rotational direction.

[0018] The shutoff flap has a driven gear adapted to engage with a gear of the transmission assembly. The arrangement of the driven gear with the gear of the transmission assembly facilitates the transmission of the rotational motion of the shaft to the pivotal movement of the shutoff flap thereby controlling the volume of the air entering into the interior of the vehicle.

[0019] The shutoff flap includes a first shutoff flap and a second shutoff flap, the first shutoff flap and the second shutoff flap have respective driven gears that are adapted to engage with the gear of the transmission assembly. The rotational motion of the gear facilitates the pivotal movement of the first shutoff flap and the second shutoff flap around the third axis thereby controlling the pivotal movement of the shutoff flap to control the volume of the air entering into the interior of the vehicle.

[0020] Further, a horizontal angular motion of the operating member operates the set of air-directive vanes to control the airflow in the sideways direction, a vertical angular motion of the operating member operates the directivity flap through the transmission assembly to control the air flowing in the first air duct or the second air duct, a rotational motion of the operating member operates the shutoff flap through the transmission assembly to control the volume of the air flowing towards the interior of the vehicle.

[0021] In another aspect of the invention, upon operating the knob in a first direction, movement of the operating member facilitates pivotal movement of the set of air-directive vanes around a first axis to control the airflow in the sideways direction, upon operating the knob in a second direction, movement of the telescopic lever facilitates pivotal movement of the directivity flap around a second axis to control the air flowing in the first air duct or the second air duct, and upon operating the knob in a rotational direction, a rotational motion of the shaft facilitates pivotal movement of the shutoff flap around a third axis to control the volume of the air flowing towards the interior of the vehicle.

[0037] An embodiment of this invention, illustrating its features, will now be described in detail. The words "comprising," "having," "containing," and "including," and other forms thereof, are intended to be equivalent in meaning and be open-ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items, or meant to be limited to only the listed item or items.

[0038] The terms “first,” “second,” and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, and the terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced item. The disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms.

[0039] The present invention provides an air vent assembly for vehicle interior which provides an air vent assembly for a vehicle interior which is operated using a single operating member. Further, the air vent assembly is adapted to hide the operating mechanism to make the air vent aesthetically appealing. Furthermore, the air vent assembly is adapted to distribute and direct the air evenly throughout the vehicle interior
[0040] Referring now to figures 1, and 2 an air vent assembly (100) for a vehicle interior in accordance with the present invention is illustrated. The air vent assembly (100) is adapted to be arranged within the trim panel of the vehicle interior and mounted at an inlet opening (5) of the air vent. The inlet opening (5) is the main source of the air flowing towards the vehicle interior and the air vent assembly (100) is provided to control the air flowing towards the interior of the vehicle. The air vent assembly (100) includes an outer housing (10) and an inner housing (20) configuring a first air duct (30) and a second air duct (40), an operating member (50), a set of air-directive vanes (60), a directivity flap (70), a shutoff flap (80), and a transmission assembly (90) to facilitate the transmission of operating member’s (50) movement to both the directivity flap (70) and the shutoff flap (80).

[0041] The outer housing (10) and the inner housing (20) are arranged in such a way that a gap formed between the outer housing (10) and the inner housing (20) configures the first air duct (30) and the second air duct (40). Specifically, the first air duct (30) is an upper duct and the second air duct (40) is a lower duct. The first air duct (30) and the second air duct (40) are configured in such a way that the air exiting from the first air duct (30) is directed in a downward direction and the air exiting from the second air duct (40) is directed in an upward direction. The inner housing (20) is a center portion of the air vent assembly (100). The inner housing (20) is adapted to enclose a portion of the operating member (50), and the transmission assembly (90).

[0042] In the present embodiment of the invention, the outer housing (10) comprises an upper shell (12) and a lower shell (14) joined together to form the outer housing (10) of the air vent assembly (100). It is obvious to a person skilled in the art to make the unibody design of the outer housing (10) or make the outer housing (10) by combining a plurality of parts. Further, the inner housing (20) comprises a front portion (22) and a rear portion (24) joined together to form the inner housing (20). It is obvious to a person skilled in the art to make the unibody design of the inner housing (20) or make the inner housing (20) by combining a plurality of parts.

[0043] The operating member (50) is operably connected with the inner housing (20), specifically, the operating member (50) is connected with the inner housing (20) using a spherical joint (25). The operating member (50) is an elongated shaft-like structure that passes through the spherical joint (25) in such a way that a portion of the operating member (50) is extended outwards from the inner housing (20) towards the vehicle interior. The other end portion of the operating member (50) is enclosed within the inner housing (20), which is not visible to the user. The end portion of the operating member (50) that is visible to the user has a knob (52) to operate the operating member (50), and the other end portion of the operating member (50) is enclosed within the inner housing (20) to make it invisible to the user.

[0044] The front portion (22) of the inner housing (20) is adapted to receive the operating member (50) through the spherical joint (25) providing the angular movement to the operating member (50) in all possible directions such as upward, downward, horizontal, and rotational. The spherical joint (25) facilitates the pivotal movement of the operating member (50) around the spherical joint (25) to operate the set of air-directive vanes (60), the directivity flap (70), and the shutoff flap (80).

[0045] Further, the set of air-directive vanes (60) is arranged at the front portion (22) of the inner housing (20) and operably connected to the operating member (50) to direct the airflow in a sideways direction. Specifically, the set of air-directive vanes (60) are provided in the first air duct (30) and the second air duct (40) to direct the airflow in a sideways direction upon operating the operating member (50). In the present embodiment of the invention, the set of air-directive vanes (60) are connected to a link bar (62) and the link bar (62) is connected to a portion of the operating member (50) through a link bar holder (621) to pivot the set of air-directive vanes (60) around a first axis (A1). The link bar holder (621) is provided to securely connect the link bar (62) to the operating member (50).

[0046] Each air-directive vane (60a, 60b, 60c, 60d, 60e, 60f) of the set of air-directive vanes (60) is arranged at a predefined distance from each other and is adapted to pivot around the respective first axis (A1a, A1b, A1c, A1d, A1e, A1f). Each air-directive vane (60a, 60b, 60c, 60d, 60e, 60f) has a leading portion and a trailing portion. The leading portion of each air-directive vane (60a, 60b, 60c, 60d, 60e, 60f) is pivotably connected to the outer housing (10), and the central portion of each directive vane is connected to the link bar (62). Upon a horizontal angular motion of the operating member (50), the link bar (62) is movable in a translatory movement to pivot each air-directive vane (60a, 60b, 60c, 60d, 60e, 60f) of the set of air-directive vanes (60) around their respective first axis (A1a, A1b, A1c, A1d, A1e, A1f).

[0047] The link bar (62) is connected to the portion of the operating member (50) in such a way that the horizontal angular motion of the operating member (50) in a right-hand direction pivots each air-directive vane (60a, 60b, 60c, 60d, 60e, 60f) around the respective first axis (A1a, A1b, A1c, A1d, A1e, A1f) to direct the air in the right-hand direction (shown in figure 3), and the horizontal angular motion of the operating member (50) in a left-hand direction pivots each air-directive vane (60a, 60b, 60c, 60d, 60e, 60f) around the respective first axis (A1a, A1b, A1c, A1d, A1e, A1f) to direct the air in the left-hand direction (shown in figure 4).

[0048] Further, the operating member (50) has a distal end which is connected to the transmission assembly (90) of the air vent assembly (100). The transmission assembly (90) is arranged between the operating member (50) and the shutoff flap (80) to facilitate the transmission of the operating member’s (50) movement to the directivity flap (70) and the shutoff flap (80). The transmission assembly (90) includes a telescopic lever (92) connected to the distal end of the operating member (50), a shaft (94) connected to a portion of the telescopic lever (92), and a gear (96) arranged on a distal end portion of the shaft (94) and operably engaged with the shutoff flap (80).

[0049] The telescopic lever (92) has a cylinder (921) and a sliding element (922) slidably arranged within the cylinder (921). The distal end of the operating member (50) is connected to the sliding element (922) of the telescopic lever (92). Specifically, the sliding element (922) has a head adapted to connect with the operating member (50). The head of the sliding element (922) and the distal end of the operating member (50) are adapted to connect with each other forming a first joint to transmit the movement of the operating member (50) to the telescopic lever (92). Further, the sliding element (922) is adapted to slide within the cylinder (921) for changing the length of the telescopic lever (92) depending upon the angular movement of the operating member (50).

[0050] For example, in an ideal position (shown in figure 1) of the operating member (50), the sliding element (922) is completely received within the cylinder (921), and the length of the telescopic lever (92) is minimal. In an extreme position (shown in figures 3, 4, 5, and 6) of the operating member (50), the sliding element (922) is almost entirely extended outside the cylinder (921) and the length of the telescopic lever (92) is maximal.

[0051] Further, the cylinder (921) of the telescopic lever (92) has a cylinder head (9211) that is adapted to connect with the shaft (94) forming a second joint between the telescopic lever (92) and the shaft (94) to transmit the movement from the telescopic lever (92) to the shaft (94). Specifically, the shaft (94) has a cavity to receive the cylinder head (9211) therein. The cylinder head (9211) of the cylinder (921) has a spherical shape, and the cavity of the shaft (94) has a hemispherical shape adapted to couple with each other to transmit the movement of the telescopic lever (92) to the shaft (94).

[0052] Further, the directivity flap (70) is provided to facilitate the closing and opening of the first air duct (30) or the second air duct (40). The directivity flap (70) is operably connected to the telescopic lever (92) of the transmission assembly (90) through a connecting element (72). The connecting element (72) is mounted on the telescopic lever (92) and is fixedly connected to the directivity flap (70). The connecting element (72) has an elongated slot (721) to receive a telescopic lever (92) therein. The elongated slot (721) provides free movement of the telescopic lever (92) in a horizontal and rotational direction, and upon movement of the telescopic lever (92) in a vertical direction, the connecting element (72) facilitates pivotal movement of the directivity flap (70) thereby controlling the direction of the air flowing in the first air duct (30) or the second air duct (40).

[0053] Specifically, the directivity flap (70) is connected to the telescopic lever (92) and is pivotally arranged at a second axis (A2). The directivity flap (70) is adapted to close the openings of the first air duct (30) or the second air duct (40). In the present embodiment, the second axis (A2) intersects the cylinder head (9211) of the cylinder (921) and is arranged at the rear portion (24) of the inner housing (20). It is obvious to a person skilled in the art to configure the second axis (A2) on any other part of the air vent assembly (100).

[0054] The directivity flap (70) is adapted to pivotably move around the second axis (A2) to close one of the air ducts that is the first air duct (30) or the second air duct (40). Upon vertical angular motion of the operating member (50), the telescopic lever (92) moves the connecting element (72) in the upward direction thereby pivotably moving the directivity flap (70) around the second axis (A2) to close the first air duct (30) or the second air duct (40).

[0055] Furthermore, the second joint is formed between the telescopic lever (92) and the shaft (94) to transmit the rotational motion of the telescopic lever (92) to the shaft (94). The cylinder head (9211) is receivable within the cavity of the shaft (94) for configuring a ball and socket joint to facilitate free angular movement of the telescopic lever (92) around the cavity of the shaft (94).

[0056] The second joint is formed in such a way that the rotational motion of the operating member (50) is transmitted to the shaft (94), and the angular movement of the operating member (50) is not transmitted to the shaft (94). Specifically, the cylinder head (9211) of the cylinder (921) is operably connected to the shaft (94) to transmit the rotational motion of the operating member (50) to the shaft (94), and the cylinder head (9211) is freely movable within the cavity during the angular movement of the operating member (50).

[0057] The second joint is adapted to transmit the rotational motion of the telescopic lever (92) to the shaft (94) thereby controlling the movement of the shutoff flap (80). The shaft (94) is rotatably arranged at the rear portion (24) of the inner housing (20) and adapted to rotate the gear (96) which is fixedly arranged at the distal end of the shaft (94). The gear (96) is rotatable around an axis that is parallel to the axis of rotation of the shaft (94). The gear (96) is adapted to engage with the shutoff flap (80) to operate the movement of the shutoff flap (80) around a third axis (A3).

[0058] The shutoff flap (80) has a driven gear (85) that is adapted to engage with the gear (96) of the transmission assembly (90). The arrangement of the driven gear (85) with the gear (96) facilitates the transmission of the rotational motion of the shaft (94) to the pivotal movement of the shutoff flap (80) thereby controlling the volume of the air entering into the interior of the vehicle.

[0059] In the present embodiment, the shutoff flap (80) includes a first shutoff flap (82) and a second shutoff flap (84). The first shutoff flap (82) and the second shutoff flap (84) have their respective driven gears (85a, 85b) that are adapted to engage with the gear (96) of the transmission assembly (90). The rotational motion of the gear (96) facilitates the pivotal movement of the first shutoff flap (82) and the second shutoff flap (84) around the third axis (A3) thereby controlling the volume of the air flowing towards the first air duct (30) and the second air duct (40) from the inlet opening (5). The first shutoff flap (82) and the second shutoff flap (84) are adapted to pivot around the third axis (A3) depending on the rotational motion of the operating member (50).

[0060] Specifically, the operating member (50) is adapted to rotate partially or completely to operate the shutoff flap (80) through the transmission assembly (90). The partial rotational motion of the operating member (50) controls the volume of air entering the interior of the vehicle, while the complete rotational motion of the operating member (50) closes or opens the inlet opening (5) of the air vent to control the volume of the air flowing towards the first air duct (30) and the second air duct (40) thereby controlling the volume of the air flowing towards the vehicle interior.

[0061] The operating member (50) is movable in a vertical direction, a horizontal direction, and a rotational direction. Specifically, the operating member (50) is movable in a horizontal angular motion to operate the set of air-directive vanes (60) through the link bar (62) to control the airflow in the sideways direction. Upon horizontal angular motion of the operating member (50) in the right-hand side direction, the set of air-directive vanes (60) are pivoted around the first axis in such a way that the air flowing from the first air duct (30) and the second air duct (40) is directed towards the right-hand side direction. Upon horizontal angular motion of the operating member (50) in the left-hand side direction, the set of air-directive vanes (60) are pivoted around the first axis in such a way that the air flowing from the first air duct (30) and the second air duct (40) is directed towards the left-hand side direction.

[0062] Further, the operating member (50) is movable in a vertical angular motion to operate the directivity flap (70) through the transmission assembly (90) to control the air flowing in the first air duct (30) or the second air duct (40). Specifically, upon vertical angular motion of the operating member (50) in the upward direction, the directivity flap (70) is pivoted around the second axis (A2) to close the first air duct (30) allowing the air to flow through the second air duct (40) which is adapted to direct the air in the upward direction while exiting from the air vent assembly (100). Similarly, upon vertical angular motion of the operating member (50) in the downward direction, the directivity flap (70) is pivoted around the second axis (A2) to close the second air duct (40) allowing the air to flow through the first air duct (30) which is adapted to direct the air in the downward direction while exiting from the air vent assembly (100)

[0063] Furthermore, the operating member (50) is movable in a rotational motion to operate the shutoff flap (80) through the transmission assembly (90) to control the volume of the air flowing towards the interior of the vehicle. Specifically, in the present embodiment, the knob (52) is fixedly attached to the operating member (50) to rotate the operating member (50) along with the rotational motion of the knob (52). The knob (52) is rotatable from the angle of 00 to 900 to configure an ideal position, a shutoff position, or a position between the ideal position and the shutoff position. In the ideal position of the knob (52) (shown in figure 7), the shutoff flap (80) is in a completely open position allowing the air to flow towards the interior of the vehicle through the first air duct (30) and the second air duct (40). In the shutoff position of the knob (52) (shown in figure 8), the shutoff flap (80) is in a completely closed position for closing the inlet opening (5) of the air vent. Further, the knob (52) is positioned between the angle of 00 to 900 to operate the shutoff flap (80) to partially close the inlet opening (5) for controlling the volume of the air flowing towards the interior of the vehicle.

[0064] In an embodiment of the present invention, the operating member (50) is movable in a first direction, a second direction or a rotational direction. Upon operating the knob (52) in the first direction, movement of the operating member (50) facilitates pivotal movement of the set of air-directive vanes (60) around the first axis to control the airflow in the sideways direction. The movement of the operating member (50) in the first direction is a horizontal angular motion. Further, upon operating the knob (52) in the second direction, movement of the telescopic lever (92) facilitates pivotal movement of the directivity flap (70) around the second axis (A2) to control the air flowing in the first air duct (30) or the second air duct (40). The movement of the operating member (50) in the second direction is a vertical angular motion. Furthermore, upon operating the knob (52) in a rotational direction, the rotational motion of the shaft (94) through the operating member (50) facilitates the pivotal movement of the shutoff flap (80) around the third axis (A3) to control the volume of the air flowing towards the interior of the vehicle.

[0065] Therefore, the advantage of the present invention is to provide an air vent assembly (100) for a vehicle interior that is adapted to operate the set of air-directive vanes (60), the directivity flap (70), and the shutoff flap (80) using the knob (52). The operating member (50) is movable around the spherical joint (25) only providing the easiness to control the air flowing in the interior of the vehicle. The advantage of the present invention is to provide the air vent assembly (100) that is adapted to hide the operating mechanism to make the air vent aesthetically appealing.
