Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and specifically relates to a vehicle. Background Art

[0002] In the prior art, vehicles use their engines to deliver power. An output shaft is located on one side of the engine, and a corresponding intake duct is located on the other. The output shaft is connected to the vehicle's transmission system to enable forward and reverse movement. The engine is located in the engine compartment. Vehicles require air conditioning. This is achieved by placing the air conditioning compressor in the engine compartment and connecting the compressor's rotating shaft to the engine's output shaft via a drive pulley and a drive belt. This distributes the engine's power. During vehicle operation, the engine's kinetic energy drives the air conditioning compressor to cool the vehicle interior. However, engine compartment space is limited, and the air conditioning compressor is typically located near the output shaft. However, vehicles also have electrical appliances, requiring a generator within the engine compartment. The generator also utilizes the engine's kinetic energy to generate electricity. Therefore, placing the generator within the engine compartment further compresses the space within the engine compartment. Furthermore, the space available in the engine compartment varies depending on the configuration of existing vehicles, resulting in different placements of the generator and air conditioning compressor. Consequently, the arrangement of the output shaft connections is irregular, requiring frequent adjustments to the drive pulley and belt layout within the engine compartment, resulting in a cluttered transmission path layout and inefficient use of engine compartment space. Moreover, when the transmission belt is too long and there are too many transmission wheels, the engine kinetic energy will be attenuated during the transmission process, and the utilization rate of the engine kinetic energy will be low.

[0003] Especially when the vehicle's cabin needs to be connected to a refrigeration device, the compressor of the refrigeration device also needs to be driven by the engine to achieve refrigeration of the refrigeration device. Existing vehicles cannot utilize the space in the engine compartment to achieve a reasonable arrangement of the generator, air-conditioning compressor and refrigeration device compressor. The engine kinetic energy is not fully utilized, and the engine power transmission path cannot be optimized, affecting the use of the vehicle. Utility Model Content
