Referring to fig. 7, an embodiment of the present invention further provides a lock control method, which can be applied to the lock. Specifically, the control method of the lock can comprise steps S101 to S103.
Step S101: a first trigger signal and a second trigger signal are acquired.
In the embodiment of the invention, the first trigger signal is generated when the latch bolt pushes against the first trigger part under the pushing of an external force and is separated from the first trigger part, and is used for representing the process that the latch bolt enters the accommodating hole corresponding to the latch bolt from the door frame. The second trigger signal is generated when the triangular tongue is pushed by external force to push the second trigger piece, and is used for representing the process that the triangular tongue enters the door frame.
Step S103: and controlling the driving piece to drive the bolt to extend out relative to the shell according to the first trigger signal and the second trigger signal.
In the embodiment of the invention, the state of the latch bolt is obtained through the first trigger signal, the state of the triangular bolt is obtained through the second trigger signal, and whether the lock can be locked or not is judged according to the states of the latch bolt and the triangular bolt. When the first trigger signal and the second trigger signal are acquired, the lock is in a lockable state, and the driving piece is further controlled to drive the bolt to extend out relative to the shell, so that locking is realized.
Further, according to first trigger signal and second trigger signal, control driving piece drive spring bolt is stretched out relatively to the casing, still includes: the driving piece is controlled to rotate along a first direction and drives the lock tongue to move to a first preset position; the driving piece is controlled to rotate to a second preset position along a second direction, wherein the first direction is opposite to the second direction, and the lock tongue is fixed at the first preset position; and controlling the driving piece to stop rotating.
Specifically, the driving member rotates in a first direction to drive the latch to move to a first preset position, which may be a clockwise rotation of the driving member, so that the latch extends out of the housing. The first preset position is the maximum distance that the lock tongue extends out of the shell in the locking process of the lock, namely, after the first preset position is reached, the driving piece does not drive the lock tongue to move any more. In the embodiment of the invention, the movement of the lock tongue to the first preset position is determined by the fact that the transmission piece cuts off the signal transmission of the third positioning piece when the controller is opposite to the third positioning piece.
The driving piece is controlled to rotate to a second preset position along a second direction, wherein the first direction is opposite to the second direction, and the lock tongue is fixed at the first preset position. In the embodiment of the invention, the second direction is that the driving element rotates anticlockwise so as to stop the rotation of the driving element. The second preset position is a rotation stopping point of the driving part. In the embodiment of the invention, the bolt moves to the second preset position, and the controller determines that the rotation stopping piece cuts off the signal transmission of the first positioning piece when the rotation stopping piece is opposite to the first positioning piece. Optionally, the rotation stopping point is used for determining that the driving member has reversed to reset, so that the driving member can normally rotate when the driving member is started next time. It should be noted that, when the driving member rotates along the second direction, the locking tongue is fixed at the first preset position, that is, the locking tongue does not move along with the driving member, and the lock still maintains the locked state.
The driving member is controlled to stop rotating, namely, when the driving member reaches a reset point, the driving member stops working.
It should be noted that, if the controller controls the driving member to perform the unlocking operation, the rotation direction of the driving member is opposite to the above. For example, after the preset verification mode is verified successfully, the driving piece drives the lock tongue to move in the second direction so as to retract relative to the shell. When the spring bolt is in the third preset position, the driving piece rotates to the second preset position along the first direction, and the spring bolt is fixed at the third preset position. And controlling the driving piece to stop rotating. The third preset position is the maximum retraction distance of the spring bolt from the shell in the lockset opening process. In the embodiment of the invention, the movement of the lock tongue to the third preset position is determined by the transmission piece cutting off the signal transmission of the second positioning piece when the controller is opposite to the second positioning piece through the transmission piece.
According to the control method of the lockset, the controller controls the driving piece to drive the bolt to extend relative to the shell according to a first trigger signal triggered when the latch bolt assembly extends after retracting relative to the shell and a second trigger signal triggered when the triangle bolt assembly retracts relative to the shell.
Use the tool to lock as the example, at this moment, get into the door frame behind the oblique tongue subassembly extrusion, triangle tongue subassembly butt door frame can confirm that the door has closed, and then driving piece drive spring bolt stretches out and locks in order to realize the automation of tool to lock, has improved the security performance of tool to lock.
