Referring to fig. 9-11, fig. 9 is a flowchart illustrating an automatic locking method for a lock body according to an embodiment of the present invention; FIG. 10 is a detailed flow chart of FIG. 9; fig. 11 is a logic block diagram of an automatic locking method.
The embodiment also provides an automatic locking method of a lock body of an intelligent door lock, as shown in fig. 9, the automatic locking method includes the following steps:
s1: the detection tongue 4 is compressed to retract into the shell 1 and drives the abutting block 41 to be separated from the locking block 51, the locking block 51 can move to one side of the scissor tongues 3, and the abutting block 41 is arranged on the detection tongue 4 and used for limiting the movement of the locking block 51.
When the detection tongue 4 is ejected, the abutment block 41 can restrict the movement of the lock block 51 to the scissor tongues 3, and when the detection tongue 4 is not ejected, the abutment block 41 no longer restricts the movement of the lock block 51, and at this time, the lock block 51 can move toward the scissor tongues 3 by the lock spring 52.
S2: after the abutting block 41 is separated from the locking block 51, if the scissor tongues 3 are popped up, the locking block 51 can move towards the scissor tongues 3 to be matched and locked with the scissor tongues, and meanwhile, the locking switch 61 is triggered; if the scissor tongue 3 is not ejected, the locking block 51 will not trigger the locking switch 61. When the detection tongue 4 is not ejected, the abutting block 41 is separated from the locking block 51, at this time, if the scissor tongue 3 is ejected, the locking block 51 can move towards the scissor tongue 3 under the action of the locking spring 52 to be matched with the locking groove 31 arranged at the inner end of the scissor tongue 3 so as to lock the scissor tongue 3, and the locking block 51 can trigger the locking switch 61 at the same time of locking, so that the scissor tongue 3 can be prevented from being compressed and retracted into the shell 1 of the lock body under the action of external force after being locked; if neither the detection tongue 4 nor the scissor tongue 3 is ejected, the door is in a virtual state at this time, and the lock block 51 abuts against the end face of the lock groove 31 and cannot be engaged with the lock groove 31, that is, the scissor tongue 3 cannot be locked.
S3: if the locking block 51 triggers the locking switch 61, the driving assembly 7 will drive the main bolt 2 to pop up to lock.
In step S2, if the detecting tongue 4 is not ejected and the scissor tongue 3 is ejected, the locking block 51 can lock the scissor tongue 3 and trigger the locking switch 61, at this time, it can be determined that the door is closed and not in a virtual state, and the driving assembly 7 can drive the main latch tongue 2 to eject, so as to achieve automatic locking. And if the detection tongue 4 is not popped out and the scissor tongue 3 is not popped out, namely when the door is in a virtual covering state, the locking block 51 cannot be matched with the scissor tongue 3 for locking, the locking block 51 cannot trigger a locking switch, the driving component 7 has no effect, automatic locking cannot be realized, hard impact between the main spring bolt 2 and the door buckle plate 9 when the main spring bolt is popped out in the virtual covering state can be avoided, and the service life of the lock body is further ensured.
In the above embodiment, as shown in fig. 10, in step S3, the driving assembly 7 ejects the driving main bolt 2 to the lock, that is, the driving assembly 7 drives the main bolt 2 to eject to the trigger lock switch 62; and further includes step S4 after step S3: after the locking switch 62 is triggered after locking, the motor 71 rotates in reverse to the home position.
That is, by providing the locking switch 62, when the main bolt 2 is ejected to the point where it triggers the locking switch 62, it indicates that the main bolt 2 is ejected to the position and locking is achieved, and at the same time, after locking (after the locking switch 62 is triggered), the motor 71 is rotated in reverse to the home position. Specifically, when the motor 71 rotates to the second trigger 73 of the driving assembly to trigger the reset switch 63, it indicates that the motor 71 has returned to the original position, i.e. the motor 71 is located at the position of the motor 71 before the intelligent door lock is locked. The motor 71 is located at the original position, namely the intelligent door lock is located at the position of the motor 71 before locking, after locking, unlocking can be achieved through reverse rotation of the motor 71, mechanical unlocking can also be achieved through a key, when the motor 71 rotates in the reverse direction to the original position, a user does not need to overcome resistance of the motor 71 when mechanically unlocking through the key, and mechanical unlocking is facilitated.
In the above embodiment, as shown in fig. 11, after step S4, step S5 is further included: after locking, if the detecting tongue 4 pops up, an alarm signal is sent out.
After the door is closed and locked, the main bolt 2 and the scissor bolt 3 are both in a popup state, the detection bolt 4 is in a non-popup state, and at the moment, if the detection bolt 4 pops up, an alarm signal is sent out to remind a user to check. Specifically, by providing the detection switch 64, the detection switch 64 can be triggered to send out an ejection signal when the detection tongue 4 is ejected, and if the ejection signal is received after locking, a failure is indicated, and an alarm is given to the user.
In the above embodiment, step S3 further includes: if the locking switch 61 is not triggered, an alarm signal is sent out. That is, if the locking switch 61 is triggered, it indicates that the scissor tongue 3 is in the pop-up state and locked by the locking block 51, at this time, the driving assembly 7 will drive the main tongue 2 to pop up for locking, if the locking switch 61 is not triggered, it indicates that the door is in the virtual state, the scissor tongue 3 and the detection tongue 4 are both in the compressed state, at this time, the user is warned, and the driving assembly 7 is not operated, so as to avoid hard impact between the main tongue 2 and the door buckle plate, and ensure the service life of the main tongue 2.
Specifically, judge the state that detects the tongue through setting up detection switch, when detecting the tongue pressurized and retract in the casing, can trigger and detect the tongue and send detection signal, and when detecting the tongue and pop out, should detect the tongue and can trigger detection switch and send out and pop out the signal, can refer to following three kinds of condition specifically:
the first condition is as follows: when the detection switch sends out a detection signal and the locking switch sends out a locking signal, the driving assembly drives the main bolt to pop out so as to realize locking;
case two: when the detection switch sends a detection signal but the locking switch does not send a locking signal, the door is in a virtual state, the driving assembly cannot drive the main bolt to pop out, and the alarm device can send an alarm signal to prompt a user;
case three: after locking (after the locking switch is triggered and sends out a locking signal), if the detection switch sends out an ejecting signal, the alarm device can send out an alarm signal to prompt a user.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
