Embodiment Construction
[0019] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings:
[0020] As shown in the figure, this embodiment includes a fixed turbine I1 and a moving turbine I2 for generating vacuum, a fixed turbine II13 and a moving turbine II14 for compression, and an anti-rotation slip for preventing the rotation of the movable turbine I2 around its axis. The block I3 and the anti-rotation slide block II12 that prevent the moving turbine II14 from rotating around its axis are used to support the body 4 of the whole device, and the eccentric wheel I5 that drives the moving turbine I2 to move with a specific law due to eccentricity and also drives the moving turbine Ⅱ14 The eccentric wheel Ⅱ11 that moves with a specific law, the motor stator 7, the motor rotor 8, and the motor shaft 9 used to generate and transmit the rotation, the bearing Ⅰ6 and the bearing Ⅱ10 used to support the motor shaft 9 and reduce rotational friction, u...

The invention relates to the field of electric automobile, and specifically relates to a vacuum compression integrated machine for electric automobile. The integrated machine comprises a machine body for supporting the whole device and a motor, which is used for generating and transmitting rotation movement. One end of the machine body is provided with a static turbine I and a moving turbine I, and the two turbines engage with each other and generate vacuum. The other end of the machine body is provided with a static turbine II and a moving turbine II, and the two turbines engage with each other and are used for compressing. The static turbine I and the moving turbine I interact with each other to vacuum, and the static turbine II and the moving turbine II interact with each other to compress air-conditioner refrigerant. A motor compressor and a motor vacuum pump are integrated into a whole, so that only one motor can realize the functions of air-conditioner cooling and vacuum power-assistance at the same time, which makes the system simpler and more reliable. Space in an automobile is saved, which utilizes the lightweight of automobile. The whole device is high efficient and low noisy. The load of the compressor is controlled by the electromagnetic decompression valve, therefore the goal of saving energy is archived, and the improvement of distance per charge of electric automobile is also benefited.
Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to a vacuum-compression integrated machine for electric vehicles. Background technique [0002] As an energy-saving and environmentally friendly future transportation tool, electric vehicles have great market prospects. Electric vehicles use the on-board power supply as the energy source to provide energy for the entire vehicle. At present, electric vehicles use electric compressors as power for cooling, and electric vacuum pumps are used to provide vacuum sources for vehicle vacuum boosters. These two systems are independent, which increases the complexity of the system and affects the reliability of the vehicle. The layout of the car brings difficulties, which is not conducive to the lightweight of the car. [0003] To sum up: the present invention proposes a vacuum-compression integrated machine for electric vehicles, which integrates the electric air-conditioning compressor an...
