Description

Technical Field

[0001] The utility model relates to the technical field of locks, and in particular to a structure for preventing a lock from being stuck by electronic components when a lock body is moved. Background Art

[0002] Smart locks are becoming more and more widely used. They not only improve security, but also bring convenience to daily life. Unlike traditional mechanical locks, they can be unlocked in a variety of ways, such as passwords, fingerprints, facial recognition, mobile phone applications, etc.

[0003] The existing automatic lock bodies on the market generally lock after the sensor tongue is pressed in and the motor rotates to lock. This locking method has the following disadvantages: when the user is locking the door, the sensor tongue is pressed in and the main lock and the secondary lock are not completely aligned with the side door frame holes. At this time, starting the motor can easily cause the main lock to press against the door frame, causing damage to the lock.

[0004] For this purpose, a lock body anti-stuck structure is proposed through electronic components. Utility Model Content

[0005] The purpose of the utility model is to solve the problems mentioned in the above background technology, and provide a lock body anti-stuck structure through electronic components.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A lock body anti-stuck structure through electronic components comprises a lock box, a panel is fixedly connected to the left side of the lock box, a secondary lock tongue induction sheet and a sensing tongue induction sheet are movably inserted on the surface of the panel, a first sensing component is arranged below the secondary lock tongue induction sheet, a driving mechanism for controlling the operation of a main lock tongue and a secondary lock tongue is installed inside the lock box, a second sensing component for sensing the status of the main lock tongue and the secondary lock tongue is also arranged inside the lock box, a motor control circuit board is fixedly installed inside the lock box, a baffle C sensing optical coupler, a mechanical key opening induction, a main lock tongue opening induction, a main lock tongue locking induction, a secondary lock tongue sensing optical coupler, a secondary lock tongue opening sensing optical coupler and a sensing tongue control switch are fixedly installed on the surface of the motor control circuit board, and the sensing tongue control switch is electrically connected to the secondary lock tongue sensing sheet.

[0008] Furthermore, the first sensing component includes a sensing lock tongue, and the sensing lock tongue is movably plugged into the panel, and a portion of the sensing lock tongue located in the lock box is provided with a sensing tongue sensing sheet.

[0009] Furthermore, the driving mechanism includes a motor, and the motor is fixedly installed inside the lock box. A transmission gear is provided at the output end of the motor. The driving mechanism also includes a gear set for pushing the main lock tongue and the auxiliary lock tongue to move, and the gear set is meshed with the transmission gear. A transmission gear zeroing sensor plate for sensing the state of the transmission gear is provided inside the lock box.

[0010] Furthermore, the second sensing component includes a main lock tongue opening and locking sensing magnet, and the main lock tongue opening and locking sensing magnet is fixedly installed inside the lock box, and an auxiliary lock tongue sensing sheet is fixedly installed on the surface of the auxiliary lock tongue.

[0011] Furthermore, an opening and closing baffle and a transmission baffle are fixedly connected to the inner wall of the lock box by bolts.

[0012] Furthermore, a mechanical key opening induction magnet is fixedly mounted on the inner wall of the lock box.

[0013] The beneficial effects of the utility model are as follows:

[0014] When the user opens the door, the program sends a signal to the motor to drive the motor to rotate; the motor drives the transmission gear to rotate, and the transmission gear opens the main lock tongue. At this time, the main lock tongue opening sensor of the motor control circuit board receives the signal and reports the signal; the transmission gear continues to rotate to open the auxiliary lock tongue. At this time, the auxiliary lock tongue opening sensor optocoupler senses the signal, and the program stops the motor for five seconds to maintain the door opening action; if the door is not opened within five seconds, the program sends a signal to the motor to rotate in the opposite direction to lock the lock; when the user closes the door, the door body is closed, and the auxiliary lock tongue and the sensor tongue will have a retracting action at the same time. The auxiliary lock tongue needs to sense the locking signal, that is, at this time the door body state is normally locked and the auxiliary lock tongue has entered the side door frame. The program starts the motor to lock the main lock tongue. By adding a sensor tongue sensor sheet at the auxiliary lock tongue position, it is ensured that the motor starts to rotate only after the door is closed normally. In use, it can effectively avoid the situation where the lock tongue is not aligned with the hole position and is stuck, thereby avoiding damage to the lock in this case.

More specifically, when the user performs the door opening action, the program sends a signal to the motor 13 to drive the motor 13 to rotate; the motor 13 will drive the transmission gear 11 to rotate, and the transmission gear 11 will then open the main lock tongue 7. At this time, the main lock tongue opening sensor 16 of the motor control circuit board 12 receives the signal and reports the signal; the transmission gear 11 continues to rotate to open the auxiliary lock tongue 8, and at this time, the auxiliary lock tongue opening induction optical coupler 19 senses the signal, and the program stops the motor 13 for five seconds, thereby maintaining the door opening action; if the door is not opened within five seconds, the program gives the motor 13 a signal to rotate in the opposite direction to lock the lock; when the user closes the door, the door body is closed, and the auxiliary lock tongue 8 and the sensor tongue will have a retracting action at the same time. The auxiliary lock tongue 8 needs to sense the locking signal, that is, at this time, the door body state is normally locked and the auxiliary lock tongue 8 has entered the side door frame, and the program starts the motor 13 to lock the main lock tongue 7. By adding a sensor tongue sensor sheet 5 at the position of the auxiliary lock tongue 8, it is ensured that the motor 13 starts to rotate only after the door is closed normally.

[0025] The first sensing component includes a sensing lock tongue, and the sensing lock tongue is movably connected to the panel 6, and the portion of the sensing lock tongue located in the lock box 21 is provided with a sensing tongue sensing piece 5. It should be noted that the sensing lock tongue and the sensing tongue sensing piece 5 cooperate to detect whether contact with the door frame occurs.

[0026] The driving mechanism includes a motor 13, and the motor 13 is fixedly installed inside the lock box 21. The output end of the motor 13 is provided with a transmission gear 11. The driving mechanism also includes a gear set for pushing the main lock tongue 7 and the auxiliary lock tongue 8 to move, and the gear set is meshed with the transmission gear 11.

[0030] In summary: when the user performs the door opening action, the program sends a signal to the motor 13 to drive the motor 13 to rotate; the motor 13 will drive the transmission gear 11 to rotate, and the transmission gear 11 will then open the main lock tongue 7. At this time, the main lock tongue opening sensor 16 of the motor control circuit board 12 receives the signal and reports the signal; the transmission gear 11 continues to rotate to open the auxiliary lock tongue 8. At this time, the auxiliary lock tongue opening sensor optical coupler 19 senses the signal, and the program stops the motor 13 for five seconds, thereby maintaining the door opening action; if the door is not opened within five seconds, the program sends a signal to the motor 13, Reverse rotation locks the lock; when the user closes the door, the door body is closed, and the auxiliary lock tongue 8 and the sensing tongue will retract at the same time. The auxiliary lock tongue 8 needs to sense the locking signal, that is, the door body is normally locked at this time, and the auxiliary lock tongue 8 has entered the side door frame. The program starts the motor 13 to lock the main lock tongue 7. By adding a sensing tongue sensing piece 5 at the position of the auxiliary lock tongue 8, it is ensured that the motor 13 starts to rotate after the door is closed normally.
