Spring bolt 100a includes a locking end that extends to the exterior of housing 10 and a connecting end that is located inside housing 10. The latch bolt driving member 20 is abutted against the connecting end of the latch bolt 100a to form driving fit.

As can be appreciated, when the latch bolt driving member 20 rotates to the driving position, the latch bolt 100a can be driven to move to the locking position, so that the latch bolt 100a and the charger are in locking fit; when the lock tongue driving member 20 rotates to the yielding position, the lock tongue 100a can move to the unlocking position, so that the lock tongue 100a can be separated from the locking fit with the charger baby, and the lock tongue driving member 20 drives the lock tongue 100a to move to the locking position through the abutting fit with the connecting end on the lock tongue 100a, so that when the lock tongue 100a is in the locking position, the lock tongue driving member 20 always abuts against the connecting end on the lock tongue 100a, so that the lock tongue 100a is limited to the locking position, and the charger baby can be effectively prevented from being stolen.

Along the circumferential outer wall of the rotating body portion 22, the rotating body portion 22 includes a first region and a second region. When the second region of the rotating body 22 abuts against the lock tongue 100a, the lock tongue 100a is in the unlock position. The abutment driving portion 23 is provided in a protruding manner in the first region to abut the tongue 100a to be in the locking position when the tongue driver 20 is in the driving position.

As can be appreciated, when the rotating body 22 rotates, the abutting driving part 23 can rotate synchronously with the rotating body 22, when the latch driver 20 rotates to the driving position, the abutting driving part 23 can abut against the connecting end of the latch 100a to move the latch 100a to the locking position, when the latch driver 20 reaches the driving position, the abutting driving part 23 continues to abut against the connecting end of the latch 100a to limit the latch 100a to the locking position, thereby limiting the latch 100a to the locking position by the abutting driving part 23 and simultaneously driving the latch 100a to move to the locking position to lock the charger baby, and in addition, by abutting and matching the second region of the rotating body 22 with the latch 100a, the latch 100a can be in the unlocking position by abutting against the latch 100a when the latch driver 20 is in the yielding position, so that the latch 100a can be limited to the unlocking position to unlock the charger baby.

In the present embodiment, the rotation body portion 22 has a disc shape, is integrally formed with the abutment driving portion 23, and along the circumferential outer wall of the rotation body portion 22, the abutment driving portion 23 includes an abutment driving surface 231 and an abutment limiting surface 232, the abutment driving surface 231 is an arc surface, and the abutment limiting surface 232 is a plane.

As shown in fig. 6 to 7, the unlocking device 100 further includes a reset element 60, where the reset element 60 is disposed in the housing 10, and is configured to move the locking bolt 100a from the locking position to the unlocking position when the locking bolt driving element 20 rotates from the driving position to the releasing position.

It will be appreciated that when locking bolt driving member 20 rotates to the unset position, locking bolt 100a moves to the unlocked position under the action of reset member 60, so that locking bolt 100a is disengaged from the charger.

As shown in fig. 6 to 7, the restoring member 60 is a compression spring, the restoring member 60 is sleeved on the lock tongue 100a, one end of the restoring member is abutted against the inner wall of the housing 10, and the other end of the restoring member is abutted against the outer wall of the lock tongue 100a indirectly or directly.

As can be appreciated, when the latch bolt 100a is in the locked position, the reset element 60 is in a compressed force-accumulating state, and the abutment driving portion 23 no longer applies a pushing force to the latch bolt 100a during the rotation of the latch bolt driving element 20 to the releasing position, and the latch bolt 100a moves to the unlocking position under the action of the reset element 60 and then abuts against the second region of the rotating body 22.

In the present embodiment, one end of the reset piece 60 abuts against the inner wall of the housing 10, and the other end abuts against the side wall of the synchronous moving piece 71.

Fig. 9 is a schematic perspective view of the latch monitor mechanism in this embodiment.

Synchronous moving member 71 is fixed to lock tongue 100 a. Photoelectric switch 72 is used to send a signal when locking bolt 100a is moved to the locked position. A switch triggering portion 73 is fixed to the synchronization moving member 71 for triggering the photoelectric switch 72 when the latch bolt 100a moves to the locking position.

As can be appreciated, when the lock tongue 100a moves to the locking position, the synchronous moving member 71 moves synchronously with the lock tongue 100a, so as to drive the switch triggering portion 73 to move to the side where the photoelectric switch 72 is located, and when the switch triggering portion 73 moves to the position corresponding to the photoelectric switch 72, the switch triggering portion 73 blocks the light beam emitted by the photoelectric switch 72, so as to trigger the photoelectric switch 72 to send a signal, thereby prompting that the lock tongue 100a has moved to the locking position.

In this embodiment, the photoelectric switch 72 is disposed outside the housing 10 and is fixed to the charging bin body, the housing 10 has an opening for the switch triggering portion 73 to move to the outside of the housing 10, the photoelectric switch 72 has a light passing hole 721 on a moving path of the switch triggering portion 73 along with the latch bolt 100a, and when the switch triggering portion 73 enters the light passing hole 721, the photoelectric switch 72 is triggered to transmit a signal. When lock tongue 100a is in the unlock position, the distance between the lock position and the unlock position of lock tongue 100a coincides with the distance between photoelectric switch 72 and switch trigger 73.

As shown in fig. 9, a guide bar 711 is provided on the synchronous moving member 71, and one end of the guide bar 711 is fixed to the synchronous moving member 71, and the other end slides through the side wall of the housing 10 for guiding during the movement of the synchronous moving member 71 along with the locking bolt 100 a.

As can be appreciated, the stability of the synchronous moving member 71 when moving with the latch bolt 100a can be ensured by the guide bar 711, and the synchronous moving member 71 can be restricted from moving in a predetermined direction so as to accurately trigger the photoelectric switch 72.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
