Technical Field

[0001] The utility model relates to the technical field of buses, in particular to an air-conditioning arrangement structure for a pure electric bus. Background Art

[0002] Currently, most pure electric passenger cars use a roof-mounted structure. However, due to road height restrictions in Hong Kong, roof-mounted air-conditioning vehicles cannot meet traffic needs.

[0003] Based on this, in order to solve the above problems of pure electric passenger vehicles, this design proposes an air-conditioning layout structure for pure electric buses. Utility Model Content

[0004] The utility model aims to provide an air-conditioning arrangement structure for a pure electric bus.

[0005] A pure electric bus air conditioning arrangement structure comprises: a body, wherein a built-in evaporator is installed at the front upper part of the body, the front lower part of the body is the front wheel, the rear lower part of the body is the rear wheel, and the air conditioning system is installed at the rear wheel.

[0006] Preferably, the air-conditioning system includes: three interior unit condensers, an air-conditioning high-voltage pre-charger box, a 3KW independent air-conditioning DCDC, and an air-conditioning gas storage tank. The three interior unit condensers are installed at the bottom of the rear wheel chassis, the air-conditioning high-voltage pre-charger box is installed on the upper part of the three interior unit condensers, the 3KW independent air-conditioning DCDC is installed on the right side of the air-conditioning high-voltage pre-charger box, and the air-conditioning gas storage tank is installed on the upper part of the 3KW independent air-conditioning DCDC.

[0007] Preferably, the three-interior condenser is connected to the pure electric compressor through a pipeline, the pure electric compressor is installed on the right side of the three-interior condenser, and the 3KW independent air conditioner DCDC is connected to the air conditioner high-voltage precharger box through a wire.

[0008] The beneficial effects of the above scheme are:

[0009] 1. This utility model places the air conditioner evaporator above the driver's seat in the vehicle, while the condenser, compressor, and other components are located on the chassis. The three-blower condenser is optimally positioned behind the left rear wheel. The pure electric compressor is designed to be installed in the space between the condenser and the rear bumper. The air conditioner high-voltage pre-charger box, 3KW independent air conditioner DC / DC converter, and air conditioner gas tank are designed to be installed in the space above the condenser, effectively utilizing space.

[0010] The air-conditioning evaporator is placed above the driver's head in the car, while the condenser, compressor and other parts are placed on the chassis, effectively reducing the height of the vehicle and better adapting to the road conditions in Hong Kong, China.

[0011] The installation structure of air-conditioning condensers, compressors and other parts is compact, and the length of the high-voltage wiring harness from the DCDC controller to the condenser and compressor is shorter than that of other nodes, which can reduce the cost of air conditioning accordingly.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0017] according to Figure 1 As shown, a pure electric bus air conditioning arrangement structure includes: a body 7, wherein the front upper part of the body 7 is equipped with a built-in evaporator 1, the front lower part of the body 7 is the front wheel 8, the rear lower part of the body 7 is the rear wheel 9, and the rear wheel 9 is equipped with an air conditioning system.

[0018] Since the air conditioning system is installed at the rear wheel position of the vehicle body 7, it can make great use of the effective space, while reducing the original top-mounted solution, thereby lowering the vehicle body to meet local height restrictions.

[0019] Specifically, the air-conditioning system includes: three interior machine condensers 2, an air-conditioning high-voltage pre-charger box 3, a 3KW independent air-conditioning DCDC4, and an air-conditioning gas storage tank 5. The three interior machine condensers 2 are installed at the bottom of the chassis of the rear wheel 9. The air-conditioning high-voltage pre-charger box 3 is installed on the upper part of the three interior machine condensers 2. The 3KW independent air-conditioning DCDC4 is installed on the right side of the air-conditioning high-voltage pre-charger box 3. The air-conditioning gas storage tank 5 is installed on the upper part of the 3KW independent air-conditioning DCDC4.

[0020] Through close installation and arrangement between air-conditioning systems, the length of high-voltage wiring harnesses and air pipes can be shortened, thereby reducing the cost of pure electric bus air-conditioning systems.

[0021] Specifically, the three-interior condenser 2 is connected to the pure electric compressor 6 through a pipeline. The pure electric compressor 6 is installed on the right side of the three-interior condenser 2. The 3KW independent air conditioner DCDC4 is connected to the air conditioner high-voltage pre-charger box 3 through a wire.

[0022] Furthermore, by re-arranging the air conditioning of pure electric buses, it is not only possible to meet the problem of urban height restrictions, but also to reduce the manufacturing cost of pure electric buses.
