In contrast, when the first gear 11 drives the two first racks 21 to move away from each other, the two first racks 21 can be separated from the through hole 221 (shown in fig. 3) of the fixing support 22 in the moving process, at this time, the two first racks 21 are not in locking relation any more, and the battery pack and the vehicle body connected with the two first racks are unlocked, so that the replacement of the battery pack can be realized.
The above-mentioned sensing assembly is configured to send out a signal in place when the first gear 11 drives the first rack 21 to sequentially pass through the two fixing brackets 22, so that the driving member stops running, and the battery pack and the vehicle body are in a locking state.
Optionally, as shown in fig. 2, the sensing assembly may include a second rack 31 and a distance sensor 32, where the second rack 13 is fixed on a side of the turntable 12 away from the first gear 11, and the second rack 13 is coaxially disposed with the first gear 11, where the second rack 31 can be meshed with the second gear 13, the distance sensor 32 is fixedly disposed and faces an end of the second rack 31, when the driving member drives the turntable 12 to rotate and the two first racks 21 relatively move, the second rack 13 rotates along with the turntable 12, so that the second rack 31 moves, a distance between the end of the second rack 31 and the distance sensor 32 becomes smaller, the distance sensor 32 can detect a distance between the end of the second rack 31 and the end of the second rack 31, and when the detected distance between the end of the second rack 31 reaches a first preset value, it is indicated that the two first racks 21 move to the right (i.e. the end of the first rack 21 stretches into the through hole 221 of the rear fixing bracket 22), and the distance sensor 32 sends a signal to the control member to the control system, so as to stop the driving member and the battery pack, thereby realizing locking and locking the driving system. In contrast, when the driving member drives the turntable 12 to rotate and the two first racks 21 move away from each other, the distance between the end of the second rack 31 and the distance sensor 32 becomes larger, and when the distance sensor 32 detects that the distance between the end of the second rack 31 and the end of the second rack reaches the second preset value, it indicates that the two first racks 21 are separated from the through hole 221 of the fixing bracket 22, and at this time, the battery pack and the vehicle body are unlocked, and the replacement of the battery pack can be performed.
Preferably, the second racks 31 and the distance sensor 32 are provided in two groups, and the two second racks 31 are provided at both sides of the second gear 13, and the position of the first rack 21 when unlocking and locking is controlled more precisely by the two groups of second racks 31 and the distance sensor 32.
