The battery pack can also be quickly locked when the operating space is limited, which increases the convenience of battery pack installation.

[0023] like Figures 1 to 4As shown, the side wall of the block 13 is fixedly connected with a connecting rod 2; the end of the connecting rod 2 passes through the side wall of the lock cover 11; the connecting rod 2 and the lock cover 11 are slidably connected; the end of the connecting rod 2 is fixedly connected with a handle 21. During operation, by arranging the connecting rod 2 on the block 13, when the battery pack needs to be removed for replacement and maintenance, the handle 21 is held and pulled outward to make the block 13 connected to the connecting rod 2 slide out from the inside of the card slot 121. When the lock cover 11 loses the engagement of the block 13, the lock cover 11 is pulled to remove the lock cover 11 from the battery pack assembly 1, and then the battery pack inside the battery pack assembly 1 is taken out for replacement and maintenance, which is more convenient and quick. At the same time, when the battery pack is taken out, the disassembly of the bolts is reduced, the problem of difficulty in operation due to lack of tools is reduced, and the convenience of installation and disassembly of the battery pack is increased.

[0024] like Figure 4 As shown, a wax block 3 is fixedly connected to the inner wall of the slide groove 12; the wax block 3 is sleeved on the connecting rod 2; the wax block 3 and the connecting rod 2 are in sliding fit. When working, the wax block 3 lubricates the connecting rod 2 to reduce the possibility of the connecting rod 2 getting stuck, thereby reducing the problem of the connecting rod 2 getting stuck when sliding, and improving the stability of the connecting rod 2 when working.

[0028] When working, the battery pack is placed inside the battery pack assembly 1, the lock cover 11 is placed above the battery pack assembly 1, and the lock cover 11 is pressed to move the lock cover 11 downward. At this time, the card block 13 is squeezed by the wall of the battery pack assembly 1 and slides into the inside of the slide groove 12. When the lock cover 11 moves down to a certain position, the slide groove 12 moves to the corresponding position of the card slot 121, and the card block 13 will pop out from the inside of the slide groove 12 under the elastic action of the first spring 14 and then enter the inside of the card slot 121, forming a card engagement with the card slot 121, thereby achieving locking. The cover 11 is fixed on the battery pack assembly 1, and the battery pack assembly 1 is quickly locked by the cooperation of the card block 13 and the card slot 121, which can make the installation of the battery pack more convenient. By providing a connecting rod 2 on the card block 13, when the battery pack needs to be removed for replacement and maintenance, the handle 21 is held and pulled outward to make the connection of the card block 13 on the connecting rod 2 slide out from the inside of the card slot 121. When the lock cover 11 loses the engagement of the card block 13, the lock cover 11 is removed from the battery pack assembly 1 by pulling the lock cover 11, and then the battery pack inside the battery pack assembly 1 is taken out and put in. Replacement and maintenance are more convenient and quick. At the same time, when the battery pack is taken out, the disassembly of the bolts is reduced. The wax block 3 lubricates the connecting rod 2 to reduce the possibility of the connecting rod 2 getting stuck, thereby reducing the problem of the connecting rod 2 getting stuck when the connecting rod 2 slides. A fixing plate 41 is provided inside the battery pack assembly 1. When the battery pack is installed inside the battery pack assembly 1, it is pushed by the lock cover 11 to squeeze the fixing plate 41, so that the fixing plate 41 and the battery pack move downward. Then, when the lock cover 11 is removed, the battery pack is bounced upward under the elastic action of the second spring 4. , making it easier to take the battery pack out from the battery pack assembly 1. By providing the vent holes 5 on the battery pack assembly 1, the heat generated by the battery pack during operation can be dissipated outward through the vent holes 5, reducing the possibility of damage to the battery pack due to overheating during operation. At the same time, a dustproof net 51 is provided on the vent holes 5 to reduce the entry of external dust and impurities into the battery pack assembly 1. By providing the elastic plate 6 inside the battery pack assembly 1, the battery pack can be clamped by the elastic plate 6 when the battery pack is placed inside the battery pack assembly 1, which can increase the stability of the battery pack inside the battery pack assembly 1.
