Generally speaking, the mounting bracket 1 is a frame structure composed of profiles, which will include support columns, and upper and lower multiple layers of fixed parts installed between the support columns, and two fixed parts on each layer respectively support the two sides of the battery pack 10. At present, in order to stably install the battery pack 10 on the mounting bracket 1, a screw hole will be opened at the front end of the fixed part and a buckle will be set at the rear end. The rear end of the battery pack 10 is fixed to the fixed part through the buckle. At the same time, a screw hole will be opened at the front end of the battery pack 10. The two screw holes form a matching hole 101, and then the battery pack 10 is locked on the mounting bracket 1 by screwing the fastening bolt into the matching hole 101.

[0027] The difference between this solution and the current method of locking the battery pack 10 by tightening bolts is that the battery pack 10 is pressed by the supporting member 2 so that the battery pack 10 will not loosen relative to the mounting bracket 1 due to factors such as vibration. At the same time, the pin 3 is inserted into the hole 101 to limit the forward, backward, left and right movement of the battery pack 10 relative to the mounting bracket 1.

The position where the abutting members 2 press is the empty space between the left and right bolts of the upper cover of the battery pack 10.

[0029] At least one latch 3 is disposed on one of the abutting members 2 and moves synchronously with the abutting member 2 ; the latch 3 is inserted into the corresponding hole 101 and locks the battery pack 10 or is disengaged from the corresponding hole 101 and releases the battery pack 10 .

[0034] The first connecting rod 42 is disposed on the mounting bracket 1 and moves horizontally and vertically relative to the mounting bracket 1. The first connecting rod 42 is hingedly connected to one end of each pry bar 41 away from the battery pack 10; one end of the second connecting rod 43 is hingedly connected to one end of the pry bar 41 facing the battery pack 10.
