Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a motor cooling cover, comprising a motor body 1, a cooling inlet 2 and a cooling outlet 3 on the motor body 1, and a cooling cover 4, a mounting seat 5 is fixedly provided on the motor body 1, a card slot 9 is provided on the side wall of the cooling cover 4, a card block slot 6 is provided on the inner wall of the mounting seat 5, a card block 8 for being inserted into the card slot 9 is provided in the card block slot 6, a control slot 10 is provided on the side wall of the card block 8 located in the card block slot 6, a pressure rod slot 13 is penetrated and provided at the inner wall of the card block slot 6 opposite to the control slot 10, a pressure rod 14 is slidably provided in the pressure rod slot 13, and the pressure rod 14 that acts with the control slot 10 to make the card block 8 slide into the card block slot 6 is slidably provided.

[0022] Specifically, a clamping block spring 7 is fixedly provided in the clamping block groove 6 , and the clamping block spring 7 is fixedly connected to the clamping block 8 . The clamping block 8 is clamped into the clamping groove 9 by the elastic force of the clamping block spring 7 , so as to limit the cooling cover 4 .

[0023] Specifically, the block 8 is located at one end outside the block slot 6 and the side away from the motor body 1 is an arc surface and inclined toward the motor body 1, which is convenient for the installation of the cooling cover 4. When the cooling cover 4 is installed, it slides down along the inner wall of the mounting seat 5. The cooling cover 4 acts on the arc surface of the block 8 to compress the block spring 7 to slide into the block slot 6. After the cooling cover 4 and the side wall of the motor body 1 are abutted, the block 8 is opposite to the slot 9. Under the elastic force of the block spring 7, the block 8 is inserted into the slot 9 to limit the cooling cover 4, completing the installation of the cooling cover 4. The inner wall of the block slot 6 away from the pressure rod slot 13 is provided with a limiting slot 11, and a limiting block 12 fixedly connected to the side wall of the block 8 is slidably provided in the limiting slot 11. The limiting of the limiting slot 11 and the limiting block 12 can prevent the block 8 from sliding out of the block slot 6 too much and interfering with the installation of the cooling cover 4.

[0024] Specifically, the inner wall on one side of the control groove 10 is an inclined surface and abuts against the pressure rod 14. The pressure rod 14 is pressed down so that it acts on the inclined surface of the control groove 10, thereby moving the block 8 into the block groove 6. The end of the pressure rod 14 that abuts against the inclined surface of the control groove 10 is an arc surface, which reduces the wear of the pressure rod 14 and the inclined surface of the control groove 10.

[0025] Specifically, a reset groove 15 is symmetrically provided on the inner wall of the pressure rod groove 13, and a reset spring 16 is fixedly provided on the inner wall of the reset groove 15 near the block groove 6. The reset spring 16 is fixedly connected to a reset block 17 fixedly connected to the side wall of the pressure rod 14. The reset block 17 is slidably connected to the reset groove 15. Pressing the pressure rod 14 drives the reset block 17 to compress the reset spring 16. After releasing the pressure rod 14, the pressure rod 14 is reset under the elastic force of the reset spring 16.

[0026] Specifically, a positioning plate 18 connected to the mounting seat 5 and abutting against the side wall of the cooling cover 4 is fixedly provided on the motor body 1, so as to facilitate the installation of the cooling cover 4. The outer wall of the cooling cover 4 is slid in against the mounting seat 5 and the positioning plate 18, so as to ensure that the block 8 is inserted into the slot 9 when the cooling cover 4 abuts against the side wall of the motor body 1.

[0027] A motor comprises any one of the motor cooling covers described above.

[0028] A specific application example of this embodiment is:

[0029] When the device is in use, when installing the cooling cover, the outer wall of the cooling cover 4 is slid against the mounting seat 5 and the positioning plate 18, and the cooling cover 4 acts on the arc surface of the block 8 to compress the block spring 7 and slide into the block groove 6, until the cooling cover 4 and the side wall of the motor body 1 are butted, and the block 8 is directly opposite to the groove 9. Under the elastic force of the block spring 7, the block 8 is clamped into the groove 9 to limit the cooling cover 4, and the installation of the cooling cover 4 is completed. When disassembling, press the pressure rod 14, and the pressure rod 14 acts on the inclined surface of the control groove 10 to move the block 8 out of the groove 9 and slide into the block groove 6. The cooling cover 4 loses its limit and can be disassembled, which is convenient for the maintenance of the motor body 1.
