The vehicle body bracket 4 is mounted on a vehicle body 6. In order to realize the self-locking, a certain size relation needs to be satisfied between the quick-release control arm 1, the battery pack adjusting pin 2 and the self-locking switch 3, and the method specifically comprises the following steps: marking the distance from the hinge point of the quick release control arm 1 and the vehicle body support 4 to the hinge point of the quick release control arm 1 and the self-locking switch 3 is L1, the distance from the hinge point of the quick release control arm 1 and the vehicle body support 4 to the first abutting surface 21 is L2, the distance from the hinge point of the self-locking switch 3 and the quick release control arm 1 to the second abutting surface 31 is L3, and then L1< L2+ L3 needs to be satisfied.
With reference to fig. 3, a hinge point between the quick release control arm 1 and the vehicle body bracket 4 is a1, a contact point between the first contact surface 21 and the second contact surface 31 is a2, and a hinge point between the self-locking switch 3 and the quick release control arm 1 is A3, that is, in a locked state, a distance from a1 to a2 is L2, a distance from a2 to A3 is L3, and a distance from a1 to A3 is L1. The locking force is provided by the quick-release control arm 1, the battery pack 5 and the vehicle body support 4 are tensioned through A1 and A3, the tensioning force is vertical F1 and F2, the A3 position can generate horizontal force F3 enabling the battery pack to tend to be unlocked, and under the condition that L1 is less than L2+ L3, the self-locking switch 3 can generate horizontal force F4 with the same size and opposite directions to offset, so that the system can be stably self-locked. In order to keep the quick release control arm 1 in a substantially vertical state after locking, an included angle formed by a connecting line of a1 and a2 and a connecting line of a2 and A3 is larger than 90 degrees and smaller than 180 degrees, an abutting part is further arranged between the vehicle body bracket 4 and the battery pack 5, preferably, a hollow part 41 is arranged on the vehicle body bracket 4, a horizontally extending abutting edge 42 is arranged at a position where the battery pack 5 is connected with the battery pack adjusting pin 2, and when locking is completed, the abutting edge 42 abuts against the hollow part 41.
With reference to fig. 4 and 5, in order to prevent the first contact surface 21 and the second contact surface 31 from being separated during or after locking of the quick-change device, the second contact surface 31 is preferably a concave surface. At this time, the first abutment surface 21 can be caught in the second abutment surface 31 to prevent the detachment. More preferably, the second abutting surface 31 may be an arc-shaped concave surface, and the first abutting surface 21 is a spherical surface matched with the arc-shaped concave surface. The spherical surface and the arc-shaped concave surface are connected, so that the self-locking switch 3 can rotate around the abutting part, the locking process is smoother, and the function of preventing the first abutting surface 21 from being separated from the second abutting surface 31 is also achieved.

Preferably, the spherical center of the first contact surface 21 and the hinge point of the quick release control arm 1 and the vehicle body bracket 4 are on the same vertical line. The above relation is satisfied, the pressing force of the quick-change device on the vehicle body bracket 4 and the battery pack 5 during locking is basically perpendicular to the abutting surface of the vehicle body bracket 4 and the battery pack 5, and the pressing force is guaranteed to be fully used for pressing the battery pack 5 and the vehicle body bracket 4.
Preferably, the self-locking switch 3 is provided with a pressing portion 32. By pressing the pressing portion 32, the battery pack 5 can be easily locked or unlocked.
With reference to fig. 3, the locking process of the quick-change device is as follows:
(1) the pressing part 32 of the self-locking switch 3 is pressed, and the self-locking switch 3 rotates anticlockwise around A3 to be in contact with the quick release control arm 1.
(2) The quick release control arm 1 is rotated clockwise to rotate clockwise about a 1.
(3) The arc concave surface of the self-locking switch 3 is contacted with the ball head part 22 of the battery pack adjusting pin 2 in the rotating process, the self-locking switch 3 continues to rotate at the moment, under the action of force, the self-locking switch 3 rotates around A3, and the arc concave surface of the self-locking switch 3 is completely contacted with the ball head part 22 of the battery pack adjusting pin 2.
