As shown in fig. 1 to 8, a battery locking and unlocking device 1 of a battery exchange station according to an embodiment of the present utility model includes a locking and unlocking head 10, a main shaft 20, a connecting sleeve 30, a spring pin 40, and a driving device 50.
The locking and unlocking head 10 is adapted to cooperate with the battery lock 2 of the battery. The spindle 20 is connected to the lock/unlock head 10. The connecting sleeve 30 is sleeved outside the main shaft 20. One of the main shaft 20 and the connecting sleeve 30 is provided with a spring pin 40 and the other is provided with a positioning groove 21, the spring pin 40 at least comprises a positioning piece 41 and a positioning elastic piece 42, the positioning piece 41 is movable between a transmission position and a disengaging position, the positioning piece 41 is matched in the positioning groove 21 in the transmission position, the positioning piece 41 is disengaged from the positioning groove 21 in the disengaging position, and the positioning elastic piece 42 normally drives the positioning piece 41 to move towards the transmission position. The driving device 50 is in transmission connection with the connecting sleeve 30.
Specifically, when the relative torque between the battery lock 2 and the driving device 50 is smaller than the predetermined torque, the driving device 50 drives the connecting sleeve 30 to rotate through the transmission with the connecting sleeve 30, the relative force between the connecting sleeve 30 and the main shaft 20 is insufficient to enable the positioning member 41 to be separated from the positioning groove 21 against the elastic force of the positioning elastic member 42, the positioning member 41 is kept at the transmission position by the positioning elastic member 42, the positioning member 41 limits the relative rotation between the connecting sleeve 30 and the main shaft 20, the connecting sleeve 30 transmits the driving force to the main shaft 20 through the positioning member 41 matched in the positioning groove 21, the main shaft 20 is driven to rotate together, the main shaft 20 drives the locking and unlocking head 10 to rotate, and the locking and unlocking head 10 drives the battery lock 2 to rotate through the matching with the battery lock 2, so that the battery lock 2 is locked or unlocked through forward rotation or reverse rotation.
When the relative torque between the battery lock 2 and the driving device 50 increases, for example, the battery lock 2 rotates to a limit position or is blocked from rotating, and exceeds a predetermined torque, the relative acting force between the connecting sleeve 30 and the main shaft 20 causes the positioning member 41 to move to the disengaging position against the elastic force of the positioning elastic member 42, so that the connecting sleeve 30 and the main shaft 20 can rotate relatively, the torque of the driving device 50 cannot be continuously transmitted to the main shaft 20, and the battery lock 2 is prevented from being damaged due to excessive torque.
It should be understood here that the predetermined torque may be adjusted by adjusting the shape and size of the positioning member 41, the elastic force of the positioning elastic member 42, etc., for example, the elastic force of the positioning elastic member 42 may be 50-200 n.
According to the battery locking and unlocking device 1 of the power exchange station, through the arrangement of the spring pin 40, whether the main shaft 20 and the connecting sleeve 30 can rotate relatively or not is controlled by the elastic force of the spring pin 40, when the torque is small, the relative rotation of the main shaft 20 and the connecting sleeve 30 is limited by the spring pin 40 so as to ensure that the driving force of the driving device 50 can be reliably transmitted to the battery lock 2, when the torque is too large, the positioning piece 41 of the spring pin 40 is separated from the positioning groove 21 so as to allow the main shaft 20 and the connecting sleeve 30 to rotate relatively, the excessive torque of the driving device 50 is prevented from being transmitted to the main shaft 20 and the battery lock 2, the battery lock 2 is prevented from being damaged by the excessive torque, and the reliability of the battery locking and unlocking device 1 of the power exchange station is improved.
