And (3) maintaining: the external force action makes the lock plate generate force for the lock plate to rotate clockwise, the lock plate limit oblique pin and the lock plate limit armature generate interaction force, the friction force between the lock plate limit armature and the support plate is increased by the action force, and the lock plate limit armature is kept motionless to play a locking role.
Unlocking: the user uses the IC card to swipe the card in the IC card area again, the ECU control system receives a signal, the ECU control system controls the push-pull electromagnetic valve to push the lock tongue limiting armature to move in the opposite direction, the lock tongue limiting oblique pin is separated from the lock tongue limiting armature, the interaction force between the lock tongue limiting oblique pin and the lock tongue limiting armature disappears, the lock tongue limiting armature is positioned at the unlocking position, the lock tongue can rotate clockwise, the limiting switch is connected, the bicycle is in the unlocking state, and the user separates the lock sheet of the public leasing bicycle from the lock groove.
Wherein the limit switch acts as: only if the locking plate is completely in place, the limit switch is closed, and the IC card can be used for functioning.
The beneficial effects of the invention are as follows:
(1) Simple structure and strong locking effect.
(2) The reliability is good; the two plane acting forces increase the friction force between the lock tongue limiting armature and the supporting plate, so that the lock tongue limiting armature is kept motionless and plays a locking role.
