[0026] The effect achieved by the entire embodiment 1 is that when the car is bumped and vibrated for a long time, the motor housing 5 vibrates, so that the mounting plate 4 is forced to drive the mounting seat 3 and the support plate 10 to move downward. At this time, under the action of the two U-shaped blocks 11 and the connecting rod 12, the movable plate 9 is driven to slide in the base 1. At the same time, the shock-absorbing spring 8 is squeezed by the movable plate 9 and begins to shrink. Under the elastic force of the shock-absorbing spring 8 and the damping action of the damper 13, it can play a role in buffering and shock absorption, so that the motor housing 5 maintains a certain stability and improves the service life of the motor.

[0027] Embodiment 2, as Figure 1 - Figure 7 As shown, the fixing mechanism 2 includes a fixing plate 201, which is fixedly connected to one side of the base 1, and a threaded hole 202 is provided on the surface of the fixing plate 201. A limiting groove 14 is provided on the outer surface of the stator body 6, and a placement groove 15 is provided on the inner surface of the motor housing 5. A reset spring 16 is fixedly connected in the placement groove 15, and a limiting block 17 is slidably connected in the placement groove 15. One end of the limiting block 17 is fixedly connected to the reset spring 16, and a clamping column 18 is fixedly connected to one end of the rotating shaft 7. A connecting head 19 is provided at one end of the rotating shaft 7, and a connecting groove 20 is provided at one end of the connecting head 19. A clamping groove 21 is provided on the outer surface of the connecting head 19, and the clamping column 18 matches the connecting groove 20. A wire housing 22 is provided on the outer surface of the motor housing 5, and a power socket 23 is connected to the top of the wire housing 22 by bolts.

[0028] The effect achieved by the entire embodiment 2 is that, by providing the fixing mechanism 2, the bolt is rotated through the threaded hole 202, so that the base 1 is fixedly installed in a suitable position, and then the stator body 6 is inserted into the motor housing 5, so that the limit block 17 is squeezed by the stator body 6 and slides into the placement groove 15, and the return spring 16 is squeezed by the limit block 17 and begins to shrink. When the stator body 6 is inserted to the target position, the limit block 17 is driven to squeeze into the limit groove 14 under the elastic force of the return spring 16, so that the stator body 6 is limited and fixed. When the stator body 6 is disassembled, the limit block 17 is pressed, and then the stator body 6 is removed from the outside of the motor. The connector 19 can be pulled out from the shell 5 for easy disassembly and assembly, which improves practicality. When replacing the connecting head 19, the connecting head 19 can be grabbed and pulled toward the end away from the rotating shaft 7 to remove the connecting head 19 from the clamping column 18. Then, the connecting head 19 matching the columnar connecting piece can be taken out, and the position of the connecting groove 20 on the connecting head 19 corresponding to the position of the clamping column 18 can be inserted. By replacing the connecting head 19, the function of replacing the clamping groove 21 is achieved, so that the connection between different columnar connecting pieces can be met. Then, the top bolt of the wire shell 22 is connected to the power socket 23, and the power supply of the external compressor can be connected through the power socket 23.

[0029] Working principle: When in use, the base 1 can be fixedly installed in a suitable position by rotating the bolt through the threaded hole 202, so that the motor housing 5 can be located in a suitable position, and the stator body 6 is inserted into the motor housing 5, so that the limit block 17 is squeezed by the stator body 6 and slides into the placement groove 15, and the return spring 16 is squeezed by the limit block 17 and begins to shrink. When the stator body 6 is inserted to the target position, the limit block 17 is driven to squeeze into the limit groove 14 under the elastic force of the return spring 16, so that the stator body 6 is limited and fixed. When the stator body 6 is disassembled, the limit block 17 is pressed and then the stator body 6 is pulled out of the motor housing 5, which is convenient for disassembly and assembly. When replacing the connecting head 19 for connection, the connecting head 19 can be grabbed and pulled to the end away from the rotating shaft 7, so that the connecting head 19 can be removed. Remove it from the card column 18, then take the connecting head 19 that matches the columnar connecting piece, and insert the part of the connecting groove 20 on the connecting head 19 corresponding to the position of the card column 18. By replacing the connecting head 19, the function of replacing the card slot 21 is achieved, so that the connection between different columnar connecting pieces can be satisfied. When the car is bumpy and vibrating during long-term driving, the motor housing 5 vibrates, so that the mounting plate 4 is forced to drive the mounting seat 3 and the support plate 10 to move downward. At this time, under the action of the two U-shaped blocks 11 and the connecting rod 12, the movable plate 9 is driven to slide in the base 1. At the same time, the shock-absorbing spring 8 is squeezed by the movable plate 9 and begins to shrink. Under the elastic force of the shock-absorbing spring 8 and the damping action of the damper 13, it can play a role of buffering and shock reduction, thereby keeping the motor housing 5 stable to a certain extent and improving the service life of the motor.
