Description
Technical Field
The invention belongs to the technical field of safety anti-theft devices, and particularly relates to a lock and a shared bicycle.
Background
The existing shared bicycle lock comprises a lock opening, a lock pin, a lock tongue, a tension spring, a spring, an electromagnetic valve driving module and a lock tongue driving component, wherein a blocking groove is formed in the lock pin, the lock pin opens or closes the lock opening through self movement, the lock tongue blocks or releases movement of the lock pin through the blocking groove which enters or exits the lock pin, the tension spring is used for endowing the lock pin with a force moving towards an unlocking direction, and the spring is used for endowing the lock tongue with a force entering the blocking groove of the lock pin. The solenoid valve driver receives an instruction signal from the CPU and controls the rotation of an output shaft of the solenoid valve. The latch driving mechanism is connected to an output shaft of the solenoid valve for converting a rotational driving force of the solenoid valve into a driving force for moving the latch out of the catch groove of the lock pin. The bolt driving component adopts a crank component, one end of the crank component is connected with an output shaft of the electromagnetic valve, a convex handle inserted into a driving hole formed on the bolt is formed at the other end of the crank component, and when the output shaft of the electromagnetic valve rotates, the convex handle is driven to rotate along a circular track taking the eccentricity as the radius.
The unlocking process of the shared bicycle lock is as follows:
when the lock tongue is positioned in the blocking groove of the lock pin, the convex handle of the crank member is standby at a non-stop block in the driving hole;
when the lock is to be unlocked, the convex handle of the crank member is blocked by the block when rotating to the position of the block in the driving hole, the convex handle pushes the block to continue rotating, so that the lock tongue is driven to move towards the direction moving out of the blocking groove, and at the moment, the spring which gives the force entering the blocking groove of the lock pin to the lock tongue is compressed; when the convex handle continues to rotate and then passes the blocking of the stop block, the lock pin loses the force moving out of the blocking groove, so that the lock pin moves towards the direction of entering the blocking groove of the lock pin under the force given by the spring until the lock pin abuts against the lock pin, the lock pin is displaced to an unlocking state under the action of the tension spring at the moment, the blocking groove moves to a position which does not correspond to the lock tongue, the lock pin abuts against the non-blocking groove part of the lock pin, and at the moment, the convex handle of the crank member rotates back to the first position for standby.
The locking process of the shared bicycle lock is as follows:
when the lock pin is pulled towards the locking direction and the blocking groove moves to the position corresponding to the lock tongue along with the movement of the lock pin, the lock tongue enters the blocking groove under the thrust of the spring and blocks the movement of the lock pin, so that the locking is completed.
It can be seen that the existing shared bicycle lock is not provided with a structure for limiting the movement of the lock pin. Therefore, under the unlocking state, the locking of the lock pin cannot be ensured when the vehicle body moves, and potential safety hazards exist.
