,TagSPECI:TECHNICAL FIELD

Embodiments of the present disclosure generally relate to an air distribution assembly of an air conditioning system of a vehicle, more particularly embodiments relates to a focus and diffused type air distribution assembly for vehicle air conditioning system.

BACKGROUND OF THE DISCLOSURE

Vehicles are provided with the air conditioning system to cool the cabin of the vehicle to take care of occupant comfort level. The air conditioning system will have significant importance in hot weather conditions to cool the cabin, and in the rainy season to clear the fog on the windshield to improve visibility. The occupant of the vehicle can optionally switch on and off the air condition system based on the requirement.

The air from the air-conditioning system is provided to the vehicle cabin through air distribution assembly also referred as air vents provided in the vehicle cabin in the locations including but not limiting to dashboard panel, roof, or on body pillars and other locations. Conventionally, vehicles are provided with either low velocity diffused type or high velocity air jet type air-conditioning units or forced ventilation units for providing conditioned or otherwise air to the vehicle cabin. Research in the area of in cab air flow management has shown that choice of air flow type largely depends on climatic conditions of the geography or terrain in which the vehicle operates. In low temperature and low humidity ambient conditions, vehicle occupants mostly prefer low intensity, low velocity diffused air inside the cabin. Whereas, in hot and humid condition (e.g. in summer in coastal areas) vehicle occupants tend to opt for more intense, high velocity air jets on body.

The conventional low velocity diffused type air vents may consist of multiple louvers, flaps inside plastic case, and are actuated either directly or through a series of kinematic linkages. The louvers or flaps may be turned on, off, partially off to control the direction and quantity of air flow from the air-conditioning. In the diffused type air vents to increase the velocity of air the speed of the blower has to be increased by the occupant, but it still does not function like an air jet. Further, the conventional air jet type air vents will have a blower disposed in the air duct, and blows the air onto the occupant like a jet.

Even though the direction and quantity of air flow may be controlled by conventional air vents such as diffused type or air jets, they do not provide choice of selecting air flow type to the vehicle occupants. Further, the traditional air vents may be good enough to control directivity and quantity, but fail to provide the options of selection of diffused verses focused air streams to vehicle occupants.

In light of foregoing discussion, it is necessary to develop an improved air distribution apparatus to overcome the limitations stated above.

To overcome the drawbacks mentioned in the background, the present disclosure provides an improved air distribution assembly of the air conditioning system for the vehicle. The air distribution assembly of the present disclosure provides a choice for the occupant of the vehicle to select either one of one low velocity diffused type or high velocity focused jet type air steam based on the requirement and the environmental condition. This would help to improve comfort level of the occupant in the cabin of the vehicle.

Referring now to figures 1 to 5, wherein the showings are for the purpose of illustrating a preferred embodiment of the disclosure only, and not for the purpose of limiting the same. In the figures neither the vehicle cabin nor the vehicle is shown. However, the vehicle as used herein above and below can be any automobile where the air conditioning system is employed.

FIG. 1 is an exemplary embodiment of the present disclosure which illustrates an exploded view of the air distribution assembly 10 for a vehicle air conditioning system. The air distribution assembly 10 includes an air distributor 12 of predetermined shape connected to the vehicle air conditioning ducting system to receive conditioned air therefrom, and distribute the same to the cabin to improve comfort of the occupant. In an embodiment of the present disclosure, the air distributor is configured in any shape, such as but not limiting to cylindrical shape. For example, the air distributor 12 is a solid cylindrical drum, which is rotatably disposed in the air duct to distribute the air into the vehicle cabin. The air distributor 12 further comprising a first type through aperture 28 (best shown in FIG. 3b) and plurality of second type through apertures 27(best shown in FIG. 3a) configured to distribute the air into the vehicle cabin. The first type through aperture 28 and the plurality of second type through apertures 27 facilitate the air flow into the vehicle cabin based on the requirement of the occupant. Further, the air distributor 12 is provided with a shaft 11 extending from at least one end 12b of the air distributor 12.

The air distributor 12 is configured to distribute air from the air duct to the vehicle cabin through either one of first type through aperture 28 or second type through apertures 27. The first type through aperture 28 is configured into high velocity forced jet unit to supply conditioned air like more intense, high velocity air jets (best visible in FIG. 5) on body of the occupant. Further, the second type through apertures 27 are configured into low velocity diffuse profile 27 (best visible in FIG. 4) to supply conditioned air into the vehicle cabin. The second type through apertures 27 include a set of narrow lateral through apertures. The diffuse profile 27 provides a low velocity and low intensity air. The first type through aperture include a single substantially circular aperture, conical aperture, any other suitable shape like rectangular aperture, square aperture and the like. This provides high velocity focused jet type air to the vehicle cabin. Further, in a preferred embodiment the size of first type through aperture 28 is configured bigger than the size of individual second type through apertures 27 to induce the forced air flow through first type through aperture 28.

As best shown in FIGs 1 and 2, the air distribution assembly 10 further includes closure 14. The closure 14 is also referred to as a “shut off cover,” is capable of being engaged with the air distributor 12. The closure 14comprises a provision 14a to receive the shaft 11 of the air distributor 12 after assembly. The closure 14 is engaged circumferentially around the air distributor 12 inside the casing 16,such that the closure 14 may be moved in same axis of the air distributor 12 to selectively cover a predefined set of first and second type through apertures 27 and 28.. In one embodiment of the present disclosure, the shut off cover/closure 14 is movably fitted with suitable mechanism such as but not limiting to snap fitted onto the air distributor 12 to move about axis of the air distributor 12 independently.

The air distribution assembly 10 is further provided with a casing 16 as shown in figures 1 through 4, to enclose or accommodate the air distributor 12 with the closure 14. In other words, the casing 16 helps in mounting the air distribution assembly 10 on the vehicle interior locations such as but not limiting to dash board, roof or any mounting places as required. The casing 16 is provided with a through opening 17 which receives the air from the air duct and distribute to vehicle cabin through the air distributor 12. The casing 16, also known as “main casing” is mounted on the vehicle air duct through mounting, such that one end of the through opening 17 is positioned in air stream and the other end is positioned towards the vehicle cabin. Further, the casing 16 is provided with provisions 13 to accommodate the shaft 11 of the air distributor 12 thereby joining the air distributor 12, and the closure 14 with the casing 16. In one embodiment of the present disclosure, the assembly of the air distributor 12 and the closure 14 is fitted inside the casing 16 with freedom to rotate independent of the casing 16. This would allow the movement of the air distributor 12 and helps the occupant to choose the high velocity air flow and low velocity air stream based on the requirement and environmental condition. Further, the assembly 10 helps the occupant to close one end i.e. end which is facing towards the vehicle cabin to stop air flow into the cabin of the vehicle.

The air distribution assembly 10 further includes plurality of knobs 18 and 20 also referred to as “kinematic levers/knobs positioned at either ends of the casing 16 to actuate the air distributor 12 and the closure 14. The knobs 18 and 20 accessible to occupier of a vehicle cabin for adjusting position of an air distributor 12 and the closure 14. The plurality of knobs includes a first knob 18 engaged with the air distributor 12 through shaft 11, where as a second knob 20 engaged with the closure 14. In one embodiment of the present disclosure, the first knob 18 is connected air distributor 12 through mechanism such as but not limiting to snap fitted to the side of the air distributor 12 to move or rotate the air distributor 12 by an occupant. The movement of first knob 18 moves the air distributor 12 to align either one of the first type and second type through apertures 27 and 28 and thus flow path is provided to air through the through opening 17 of the casing 16. Such movement of the air distributor 12 will provide the choice to the occupant for selecting either one of the low velocity diffuse air vents and high velocity forced jet air vent. The second knob 20 is connected to closure 14 through mechanism such as but not limiting to snap fitted to the side of the closure 14. The movement of second knob 20 moves the closure 14 to regulate the flow of air through the air distributor 12. Such movement of the closure 14 will provide the option to the occupant optionally open and close the through opening 17 of the casing 16. Each first and second knob 18 and 20 has serrated profiles 25 on inner surfaces i.e. the surfaces facing side face of the casing 20. Corresponding to the serrated profiles 25 on inner surfaces, the casing 16 includes one or more spring loaded plunger sockets 30. The plunger or ball is forced against the serrated profile 25 on the inner face of the lever, after assembly; to provide controlled rotation and haptics, this would arrest the free play of knobs 18 and 20.

Referring again to FIG. 1, the air distribution apparatus 10 further includes a cover plate 22 placed in front of the casing 16 when mounted on air duct of the vehicle. The cover plate 22 includes an opening and a set of slots 24 and 26 at either ends. The opening of the cover plate 22 is aligned with the through opening 17 of the casing 16. The set of slots, namely 24, 26 correspond to the set of knobs 18, 20, therefore when the cover plate 22 is assembled over the casing 16, the knobs 18, 20 extend through the slots 24, and 26. The cover plate 22 is fixed to the air ducts through suitable mechanism such as but not limiting to snap fit, fastening, and riveting.

The air distributor 12 is turned to provide either focused or diffused air stream by turning the first knob 18 also referred as left kinematic lever. By turning the second knob 20 also referred as right knob, the closure 14 can be turned to switch the vent “on or off”. The whole assembly can be swiveled around the axis of ball joint K; mounted on the top of the casing 16 for direction control. A front plate fixed on the main casing which in turn can be assembled on dash panel, independent of the remaining assembly.

In addition to the diffused and focused modes, the adjustment of the shut off cover may also control the supply of the air quantity. The ball and socket mounting on the top of main casing 16 provides the assembly a minimum three degrees of freedom in X, Y and Z direction for better throw direction and orientation control. The design consists of the only five main sub-assemblies leading to reduction in part count, weight, ease of assembly.

FIG. 2 is an exemplary embodiment of the present disclosure which illustrates an assembled view of the air distribution apparatus 10 of the air conditioning system of the vehicle with closure 14 in closed condition. The closure 14 can be turned to switch the vent “on or off” with the help of second knob 20 which would regulate the flow of air through the air distributor 12 into the vehicle cabin. The occupier of the vehicle cabin can operate the second knob 20 to open and close the through opening 17 of the casing 16. The movement of closure 14 helps to open and close through opening 17 of the casing 16 to facilitate the air flow through the through opening 17 when it is required.
