Rotary locking mechanism, lock having the same, and locking control method of the lock
First Claim
1. A rotary locking mechanism, comprising:
- a rotary output member, a first locking member, a second locking member and a switching member, whereinthe rotary output member is connected to a rotary member to transmit rotation power, and a rotation circumference of the rotary output member is provided with a plurality of locking grooves;
the first locking member and the second locking member are respectively elastically hinged at two hinge points, the first locking member is provided with a locking block engageable in any one of the locking grooves, and the second locking member and the first locking member abut against each other at a position outside a straight line in which the two hinge points are located, to allow the locking block of the first locking member to be engaged into the locking groove; and
the switching member is connected to a locking control system and has a first unlocking structure and a second unlocking structure configured to sequentially push the second locking member and the first locking member respectively; and
the locking control system comprises a motor configured to control swinging of the switching member, wherein the motor and the switching member are separately arranged, an output end of the motor is connected to a control block performing a rotational movement, and one point on a rotation circumference of the control block is connected to a non-hinged point of the switching member via a control wire.

Abstract
A rotary locking mechanism and a lock applying the rotary locking mechanism and a locking control method are provided. A rotary output member is locked by a stable triangular supporting structure between the first locking member and the second locking member, the effective constraint of the second locking member on the first locking member applied by the first locking member in both a locked state and an unlocked state achieves locking and unlocking reliability of the product. The entire locking mechanism is controlled by the same switching member. The false locking operation when the rotary member is operating is effectively avoided through the mechanical structure and the automatic control method. The entire rotary locking mechanism is enclosed and fixed in a shell of the lock, and can be applied to transmission machinery of bicycles, electric vehicles, motorcycles and even lightweight automobiles.
