At this time, the stopper rod 41 of the stopper 4 is aligned with the first recess 21 and is received in the first recess 21. Thereby, the lock ring 2 is stopped by the stopper 4 and held at the unlock position. Note that, the stopper elastic member 8 is in a compressed state. The curved profile portion 62 does not limit the limiting member 4. The stopper elastic member 8 in a compressed state applies a force to the stopper 4 so that the lower end of the stopper 4 is received in the first recess 21.

The unlocking and locking process is described below with reference to fig. 1 and 4:

when the user wants to unlock the lock, the user can operate to start the motor. The motor rotates the cam by a first angle in a predetermined direction so that the stopper 4 is away from the locking ring 2 and away from the second recess 22. The stopper 4, which is away from the second recess 22, no longer stops the lock ring 2. The locking ring 2 moves from the locked position to the unlocked position under the pulling force of the locking ring spring 3 and reaches the unlocked position. The cam continues to rotate in the predetermined direction during movement of the locking ring 2 from the locked position to the unlocked position until the curved profile 62 of the cam passes over the limiting body 42 and no longer limits the limiting member 4. The stop 4 is aligned with a first recess 21 in the locking ring 2 that reaches the unlocked position. The stopper elastic member 8 in the compressed state applies a force to the stopper 4 toward the locking ring 2 until the stopper rod 41 of the stopper 4 is received in the first recess 21.

When the user wishes to close the lock, the user may pull the handle 5 to move the locking ring 2 from the unlocked position to the closed position. Since the position-limiting member 4 is held in the first recess 21 by the force applied thereto by the position-limiting member elastic member 8 in the compressed state, the user is not hindered by the position-limiting member 4 when the user can pull the handle 5. After the locking ring 2 moves to the locking position, the retainer 4 moves toward the locking ring 2 under the action of the retainer elastic member 8 in a compressed state until the retainer rod 41 of the retainer 4 is received in the second recess 22. The lock ring 2 is retained in the closed position by a stopper 4.

The utility model discloses a lock has following advantage at least:

first, the lock of the present invention can also be held in the unlocked position when the locking ring elastic member 3 is broken, without causing a safety accident. This is because the locking ring 2 is not only held in place in connection with the locking ring spring 3, but is further held in place by being stopped by the stopper 4.

Second, the utility model discloses a lock simple structure and simple operation. Specifically, when the user needs to lock the vehicle, the user only needs to pull the handle 5. The recess left side portion 212 and the recess right side portion 213 in the first recess 21 can guide the stopper 4 so that the user can pull the lock ring 2 with a small force.

Although the present invention uses the motor and the cam as the example of the driving device 7, those skilled in the art can understand that any device that can drive the position-limiting member 4 to move relative to the lock ring 2 and the lock frame 1 falls into the protection scope of the present invention.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
