Vehicle-mounted heating, ventilation and air conditioning assembly and vehicle

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on January 2, 2024, with application number 202420005359.7 and invention name “A vehicle-mounted HVAC assembly and vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of vehicle-mounted air conditioning, and in particular to a vehicle-mounted heating, ventilation and air conditioning assembly and a vehicle. Background Art

[0004] The HVAC system plays a key role in heating and cooling in cars. It contains multiple components such as the evaporator, heater core, and blower assembly, and has the function of adjusting air volume and air conditioning mode. Therefore, the HVAC system is a key component in cars.

[0005] Existing HVAC systems are primarily categorized as offset and center-mounted. Each has its own advantages and disadvantages. The offset blower is located to the left or right of the evaporator. While the offset distribution box is smaller, the presence of the air inlet box occupies space below the dashboard in the passenger area. Center-mounted systems house the blower and evaporator in the same area, with the air inlet located to the left or right of the HVAC unit. Traditional center-mounted systems require filters, dampers, and other components, resulting in a larger air inlet and occupying more space below the dashboard in the passenger area.

[0006] However, with the booming automotive industry, many car models are being developed globally, requiring both left-hand and right-hand drive models. If the HVAC design is not compatible with both, when developing export models, the steering mechanism will need to be repositioned, requiring mirrored HVAC design and development. This will require redesigning and re-molding the HVAC, and re-developing the corresponding front wall panels and steering support. This will increase the development costs of the entire vehicle by tens of millions, resulting in significant waste.

[0007] Therefore, for models developed globally, it is urgent to develop a new HVAC system that is compatible with left and right drive models to meet the needs of different regional markets. Summary of the Invention

[0035] The following will describe the embodiments of the present application with reference to the accompanying drawings and optional embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the optional embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0036] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0037] As shown in Figures 1-8, the present application proposes a vehicle-mounted HVAC assembly 100. The vehicle-mounted HVAC assembly 100 includes an air conditioner body 10 and an optimization component disposed within the air conditioner body 10, the optimization component being used to optimize the internal layout space of the air conditioner body 10.

[0038] The optimized assembly includes an air conditioning filter element 120 and a sliding damper 111. The air conditioning filter element 120 is configured as a multi-stage structure. Optionally, the air conditioning filter element 120 includes an upper filter element 1202 and a lower filter element 1201. Of course, in actual applications, the air conditioning filter element 120 can be configured with three or more sections. This can reduce the space required to install the air conditioning filter element 120, thereby reducing the overall size of the air conditioner.

[0039] Compared to the rotary defrost damper 114 (described below), the sliding damper 111 provided in this application reduces the internal space required for the damper's opening and closing process, thereby assisting the air conditioning filter 120 in reducing the size of the air conditioner main body 10. This eliminates the need to occupy the space below the dashboard in the driver's area, allowing installation in both left-hand and right-hand drive vehicles, ensuring compatibility with both. The sliding damper 111 can be adjusted to adjust its opening ratio based on control requirements, thereby achieving different mixing ratios of cold and warm air.

[0040] As shown in Figures 1, 2, 3 and 4, a schematic diagram of the vehicle-mounted HVAC assembly 100 is shown, and the vehicle-mounted HVAC assembly 100 is highly integrated. The blower assembly 110 is arranged adjacent to the internal and external circulation air duct 170. One end of the internal and external circulation air duct 170 is connected to the blower assembly 110, and the other end is provided with a filter 103. The filter 103 is used to prevent large debris outside the vehicle from entering the air duct. The vehicle-mounted HVAC assembly 100 has a mode actuator 121, a right-side heating and cooling actuator 122, a left-side heating and cooling actuator 123 and an internal and external circulation actuator 124, and the above actuators are all arranged on the air-conditioning main body 10. A drain pipe 160 is provided at the bottom of the air-conditioning main body 10.

[0041] As shown in Figures 4 and 5, the internal and external circulation air duct 170 is located on one side of the air conditioner main body 10. The internal and external circulation air duct 170 is relatively small and does not extend beyond the boundary formed by the three sides of the air conditioner main body 10. The air conditioner main body 10 is also provided with a refrigerant expansion valve interface 1001 and a HVAC water pipe interface 1002. The refrigerant expansion valve interface 1001 and the HVAC water pipe interface 1002 are symmetrically located on one side of the air conditioner main body 10 along the blower assembly 110.

[0042] 6 , a water trough 180 is provided at the bottom of the air conditioner body 10. This trough 180 is detachably connected to the air conditioner body 10. This allows for modifications to the trough 180 based on subsequent needs without changing the design of the vehicle HVAC assembly 100. The refrigerant expansion valve connecting pipe is covered with a cover plate 190.

[0043] 5 and 7 , the air conditioner body 10 is provided with a front air vent 104, a defrost air vent 105, a rear air vent 106, a center row left air vent 107, and a center row right air vent 108. These air vents are used to provide cooling or heating to various parts of the vehicle, and the relevant content is relatively mature in the prior art and will not be described in detail here.

[0044] The vehicle HVAC assembly 100 is provided with six mounting points, including an upper left mounting point 1003, an upper right mounting point 1004, a lower left mounting point 1005, a lower right mounting point 1006, a left mounting point 1007, and a right mounting point 1008. The upper left mounting point 1003, the upper right mounting point 1004, the lower left mounting point 1005, and the lower right mounting point 1006 are connected to the steering support, while the left mounting point 1007 and the right mounting point 1008 are connected to the front wall panel.

[0045] As shown in Figure 8, the air conditioner main body 10 is also equipped with an evaporator assembly 130, a first heating core 140, and a second heating core 150. The vehicle-mounted HVAC assembly 100 utilizes a three-core design. The air conditioning filter 120 is located in front of the evaporator assembly 130. The first heating core 140 and the second heating core 150 are positioned adjacent to each other. The first heating core 140 can be a warm air core or a built-in condenser, depending on the system architecture. The second heating core 150 can be an air-heated electric heater or a warm air core, depending on the system architecture.

[0046] The air duct in the air conditioner main body 10 is further provided with a defrost damper 114, a front blow damper 113, and a rear blow damper 112. The defrost damper 114, the front blow damper 113, and the rear blow damper 112 are all rotatably connected to the air conditioner main body 10. By controlling the opening and closing of different dampers, the flow direction of the cold and warm air is guided.

[0047] The present application also provides a vehicle, which includes a vehicle body and an on-board HVAC assembly 100 arranged on the vehicle body.

[0048] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto.
