Description: AN OUTSIDE REAR VIEW MIRROR BASE

TECHNICAL FIELD
[0001] The present subject matter described herein relates to an outside rear-view mirror (ORVM) on a vehicle. More specifically, the present invention relates to an ORVM base structure that is connected to the front doors of a vehicle body. The present invention improves the noise performance near the ORVM area by improving the shape of the ORVM base structure to streamline the airflow.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present subject matter. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] A vehicle's front doors have an outside rear-view mirror (ORVM) that are affixed to the left side and the right side. The ORVM housing is round in shape. Since the ORVMs are over-hanged parts on the vehicle, a lot of turbulence is created around the ORVM when the vehicle is running at a high speed.
[0004] While in vehicle running condition when the wind blows against the vehicle body and around the ORVM, it hits the ORVM from behind. The wind that hits the ORVM from behind is dispersed and is further split by the ORVM, allowing it to flow backward.
[0005] When the car is running, a lot of turbulence is created around the ORVM due to wind, as mentioned above. As a result, a passenger may perceive the change in sound pressure of wind induced by the turbulence of the air currents as a noisy sound.
[0006] Referring to FIG. 1(A) in an existing design, the base region (101) is kept flat which increases the air turbulence and reduce the noise performance. The base region (101) is also known as a wake region. Further, the wake region near an ORVM housing (102) during the running of the vehicle at high speed is an important factor in producing noise around the ORVM in the vehicle.
[0007] Further, there are gaps (103, 104) between the ORVM housing (102) and base (101). When the air pass through these gaps (103, 104) at high speed, a whistle noise is created as the flow of the air is not streamlined (as seen in section A-A and provided in FIG. 1(B) thereby creating noise.
[0008] Therefore, it is required to provide an improved ORVM base to achieve the streamlined airflow around the base in order to reduce noise.

OBJECTS OF THE DISCLOSURE
[0009] It forms an object of the present disclosure to overcome the aforementioned and other drawbacks/limitations in the existing solutions available in the form of related prior arts.

[0033] Hereinafter, a description of an embodiment with several components in communication with each other does not imply that all such components are required. On the contrary, a variety of optional components are described to illustrate the wide variety of possible embodiments of the present disclosure.
[0034] The present invention discloses an Outside Rear View Mirror (ORVM) base that is connected to a front door of a vehicle body. The ORVM base is improved by providing an angled shape structure and streamlining the airflow in an upwards and downwards directions, thereby reducing the noise.
[0035] Referring to FIG. 2(A) shows the ORVM base (200). The ORVM base (200) is connected to the front door of the vehicle body. The ORVM base (200) has a side surface (201) that is adapted to connect with the front door of the vehicle body. The side surface (201) is connected to a first surface (202). A second surface (203) is extended in a horizontal direction from one side of the first surface (202). Further, the second surface (203) comprises a first face (204) and a second face (205).
[0036] The ORVM base (200) includes the side surface (201) that is fixed to the front door of the vehicle body. Further, the side surface (201) is located in a perpendicular direction with respect to the first surface (202). The first surface (202) is extended horizontally in the direction opposite to the front door of the vehicle body.
[0037] The first surface (202) is flat and has a hole (210) to mount and accommodate an ORVM housing (102) (as illustrated in FIG. 1(A)) on top of it. Further, the first surface (202) is connected to the side surface (201) and lies adjacent to the side surface (201). The first surface (202) is protruded from the side surface (201) towards the outer side in a vehicle width direction forming the second surface (203) and thereby increasing the overall surface area of the first surface (202).
[0038] The second surface (203) includes the first face (204) and the second face (205). The first face (204) angularly moves in a downwards direction and the second face (205) angularly moves in an upwards direction forming an angled shape structure (211).
[0039] The area of the first face (204) increases from a first end (206) of the first face (204) to a second end (207) of the first face (204). The second end (207) of the first face (204) is fixed to the side surface (201). Moreover, the area on the second end (207) is greater than the first end (206).
[0040] The second face (205) is continued from the first face (204) in a downwards direction. Further, the second face (205) moves in the downwards direction from points of inflection. The points of inflection are created at the end of the first face (204). Thereby, from the points of inflection, the first face (204) is angled in the upwards direction and the second face (205) is angled in the downwards direction.
[0041] The area of the second face (205) increases from a first end (208) of the second face (205) to a second end (209) of the second face (205). The first end (208) of the second face (205) is curved and overhanged in the air and the second end (209) of the second surface (203) is fixed to the ORVM housing (102) (as illustrated in FIG. 1(A)) from the backside. Most of the area on the second face (205) is affixed to the ORVM housing (102) (as illustrated in FIG. 1(A)) to provide support and strength.
[0042] The first end (206) of the first face (204) is in an opposite direction to the first end (208) of the second face (205). Further, the combination of the first face (204) and the second face (205) forms the angled shape structure (211). The angled shape structure (211) faces the front of the vehicle. The angled shape structure (211) here acts as a wake region. The angled shape structure (211) performs as the region facing the disturbed airflow downstream (which is often turbulent) and is aligned with the airflow direction.
[0043] Since the first face (204) is angled in the upwards direction, the airflow moves along with the upwards angle and towards the ORVM housing (102) (as illustrated in FIG. 1(A)). Further, as the second face (205) is angled in the downwards direction, the airflow moves towards the downwards direction. Therefore, the movement of the airflow in the upwards and the downwards direction creates a streamlined flow of air which is suitable to reduce noise in the present disclosure.
[0044] Referring FIG. 2(A) and 2(B) discloses the travel path of the wind/air in the presence of the angled shape structure (211) (as seen in section B-B). The angled shape structure (211) aids in providing the streamlined airflow which has reduced the wake region and improved the noise performance.
[0045] The first face (204) creates a uniform airflow towards the ORVM housing (102) mounted on the first surface (202), wherein a small gap between the ORVM housing (102) and the first face (204) has a turbulent zone (vortex) in front of it. Therefore, the arrangement of the first face (204) with an upwards angle leads to a smooth flow of air thereby avoiding interference with the turbulent zone.
[0046] The air travels from the first face (204) towards the ORVM housing (102) where the air is further transported in the upwards direction after hitting the ORVM housing (102) and avoids interacting with the turbulent zone (vortex) in front of the small gap between the ORVM housing (102) and the first face (204). The air also travels from the second face (205) is the downwards direction. Therefore, a streamlined airflow is produced (as shown in section B-B).
[0047] Further, the angled shape structure (211) helps to streamline the airflow which has reduced wake region and improved the noise performance.

TECHNICAL ADVANTAGES
[0048] With the help of the solution as proposed herein in the context of the present disclosure, when the wake region is reduced to provide for a streamlined air flow.
[0049] The design of the present disclosure the noise level is reduced.
[0050] The ORVM base has improved the turbulence and has also aided in the smooth airflow.
[0051] The ORVM base is strengthened by the angled shape structure.
[0052] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation, no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to disclosures containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. Also, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general, such construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to “at least one of A, B, or C, etc.” is used, in general, such construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

The present disclosure contemplates all of these combinations. Unless stated otherwise, dimensions and geometries of the various structures depicted herein are not intended to be restrictive of the disclosure, and other dimensions or geometries are possible. Also, while a feature of the present disclosure may have been described in the context of only one of the illustrated embodiments, such feature may be combined with one or more other features of other embodiments, for any given application. It will also be appreciated from the above that the fabrication of the unique structures herein and the operation thereof also constitute methods in accordance with the present disclosure.
