Based on the above settings, the lock body device in the embodiment of the present application can realize various control logics, such as controlling the unlocking of the latch bolt 200, controlling the unlocking and locking of the square tongue 300, and controlling the latch bolt 200, The square tongue 300 is controlled, so that the function of the state of the lock body is more powerful. At the same time, the lock body device in the embodiment of the present application also has higher control precision, so that the oblique tongue 200 and the square tongue 300 can be extended or retracted in due time, thereby ensuring the high-efficiency operation of the lock body device.

In the embodiment of the present application, when the lock body device is applied to the door, when the door is in the open state, the oblique tongue 200 is stretched out, the square tongue 300 is retracted, and the induction tongue 1200 is stretched out; when the door is in the fully locked state, The oblique tongue 200 is extended, the square tongue 300 is extended, and the induction tongue 1200 is retracted; when the door is in the locked state of the square tongue 300, the oblique tongue 200 is retracted, the square tongue 300 is extended, and the induction tongue 1200 is retracted; When the door is unlocked and the door is closed, the oblique tongue 200 retracts, the square tongue 300 retracts, and the sensing tongue 1200 retracts; when the door is fully unlocked and opened, the oblique tongue 200 retracts, the square tongue 300 retracts, and the sensing tongue 1200 stick out.

In some embodiments, the lock body device includes two sets of fourth detection elements 1340, the first transmission mechanism 500 has a first detection portion 513, and when both the oblique tongue 200 and the sensing tongue 1200 are extended, the first detection portion 513 Corresponding to the position of the first group of fourth detection elements 1340 , when the oblique tongue 200 , the square tongue 300 and the sensing tongue 1200 are all retracted, the first detection part 513 corresponds to the position of the second group of fourth detection elements 1340 . Optionally, the first detection part 513 may be a stopper protruding from the first transmission mechanism 500. When the first detection part 513 corresponds to the position of the fourth detection element 1340, the first detection part 513 will detect the fourth detection element 1340. The detection part of 1340 is shielded, so that the fourth detection element 1340 is disconnected. In one embodiment, the fourth detection element 1340 is a photoelectric switch. When the first detection part 513 moves to the position corresponding to the fourth detection element 1340, the first detection part 513 will block the light. At this time, the fourth detection element Step 1340 may determine that the first detection part 513 is located at this position, so as to obtain information about the rotational position of the first transmission mechanism 500 .

Based on the above settings, when the door using the lock body device is opened, both the oblique tongue 200 and the sensing tongue 1200 are stretched out, and the square tongue 300 is retracted. A detection part 513 is located at the position of the first group of fourth detection elements 1340 . When the door is closed and the oblique tongue 200 and the square tongue 300 are unlocked, the oblique tongue 200, the square tongue 300 and the sensing tongue 1200 all retract. At this time, the first detection part 513 on the first transmission mechanism 500 is located at the second The positions of the two sets of fourth detection elements 1340 . In this way, the position information of the first transmission mechanism 500 can be determined according to the detection results of the two groups of fourth detection elements 1340 , and the position information of the latch tongue 200 or the square tongue 300 can be further determined.

In some embodiments, the lock body device further includes a fifth detection element 1350 for detecting the locking of the square tongue 300. Correspondingly, the second transmission mechanism 600 has a second detection portion 612. When the square tongue 300 is extended Below, the second detection part 612 corresponds to the fifth detection element 1350 . Optionally, the second detection part 612 may be a stopper protruding from the second transmission mechanism 600. When the second detection part 612 corresponds to the position of the fifth detection element 1350, the second detection part 612 will detect the fifth detection element. The detection part of 1350 is shielded, so that the fifth detection element 1350 is turned off. In one embodiment, the fifth detecting element 1350 is a photoelectric switch. When the second detecting part 612 moves to the position corresponding to the fifth detecting element 1350, the second detecting part 612 will block the light. At this time, it can be determined that the second The detection part 612 is located at this position, so as to obtain the rotational position information of the second transmission mechanism 600 .

Based on the above settings, when the door using the lock body device is closed and the lock body device is fully locked, both the oblique tongue 200 and the square tongue 300 are stretched out, and the sensing tongue 1200 is retracted. Therefore, in the above situation, the first The second detection part 612 on the second transmission mechanism 600 is located at the position of the fifth detection element 1350 . In this way, the position information of the second transmission mechanism 600 can be determined according to the detection result of the fifth detection element 1350 , so as to determine whether the square tongue 300 is completely locked.

In some embodiments, when the oblique tongue 200 and the sensing tongue 1200 are stretched out, and the square tongue 300 is retracted, the first detection element 1310 is turned off, the second detection element 1320 is turned on, and the third detection element 1330 is turned on , the first group of fourth detection elements 1340 is turned off, the second group of fourth detection elements 1340 is turned on, and the fifth detection element 1350 is turned on. At this time, the door using the lock body device is in an open state. In this state, the user can drive the door to close. As the door is closed, the latch tongue 200 will touch the door frame and gradually retract into the base 100, so that the first detection element 1310 is switched from the off state to the on state. At the same time, the sensing tongue 1200 will also touch the door frame and retract into the base 100, so that the third detection element 1330 is switched from the on state to the off state. When the door is fully closed, the latch tongue 200 will protrude again, so that the first detection element 1310 is switched from the on state to the off state again. During the above door closing process, the second detection element 1320 remains in the on state, the first group of fourth detection elements 1340 remains in the off state, the second group of fourth detection elements 1340 remains in the on state, and the fifth detection element 1340 remains in the on state. Element 1350 is in the ON state unchanged.

After the door is completely closed, the detection result of each detection element is the same as the preset result in the control element 1400, so it is judged as normal door closing, and then after a short period of time (such as, 3 seconds, etc.), the control element 1400 controls the drive mechanism 1000 to start, The driving mechanism 1000 drives the first transmission mechanism 500 to rotate, the first transmission mechanism 500 drives the second transmission mechanism 600 to rotate, and the second transmission mechanism 600 drives the square tongue 300 to protrude relative to the base 100 to realize the locking of the square tongue 300.

Since the second transmission mechanism 600 rotates to drive the square tongue 300 to lock, the second detection part 612 will rotate with the second transmission mechanism 600 during this process. When the square tongue 300 is locked, the second detection part 612 just rotates to the fifth detection position. position of the component 1350, and disconnect the fifth detection component 1350, so that the fifth detection component 1350 can detect the second detection part 612, and send the detection result to the control component 1400, so as to determine that the square tongue 300 is locked normally.

In some embodiments, when the oblique tongue 200 and the square tongue 300 are stretched out, and the sensing tongue 1200 is retracted, the first detection element 1310 is disconnected, the second detection element 1320 is disconnected, and the third detection element 1330 is disconnected , the two sets of fourth detection elements 1340 are turned on respectively, and the fifth detection element 1350 is turned off. At this time, the door using the lock body device is in a closed state, and the lock body device is completely locked. Then the user can input unlocking information, such as fingerprints, swiping cards, etc. After the control element 1400 receives the unlocking information input by the user, it controls the drive mechanism 1000 to start, and the drive mechanism 1000 drives the square tongue through the first transmission mechanism 500 and the second transmission mechanism 600 in turn. 300 retracts relative to the base 100 , thereby unlocking the other tongue 300 . At the same time, the driving mechanism 1000 can also drive the latch bolt 200 to retract relative to the base 100 through the first transmission mechanism 500 , so as to unlock the latch bolt 200 . It should be noted here that, in the above unlocking process, under the driving action of the driving mechanism 1000 , the square tongue 300 and the oblique tongue 200 can be unlocked simultaneously.

When neither the square tongue 300 nor the oblique tongue 200 is unlocked, the first detection part 513 is located on the side of the first group of fourth detection elements 1340 away from the second group of fourth detection elements 1340, and the second detection part 612 is connected to the second group of fourth detection elements 1340. The five detection elements 1350 are arranged oppositely; when the square tongue 300 and the oblique tongue 200 are fully unlocked, the first detection part 513 rotates to a position opposite to the second group of fourth detection elements 1340, and the second detection part 612 is separated from the second group of fourth detection elements 1340. At the same time, during the unlocking process of the square tongue 300 and the oblique tongue 200, the first detection element 1310 is switched from the off state to the on state, and the second detection element 1320 is switched from the off state Switching to the on state, the third detection element 1330 remains in the off state.

In other embodiments, when the oblique tongue 200 is extended and the square tongue 300 and the sensing tongue 1200 are both retracted, the first detection element 1310 is turned off, the second detection element 1320 is turned on, and the third detection element 1330 is turned off , the first group of fourth detection elements 1340 is turned off, the second group of fourth detection elements 1340 is turned on, and the fifth detection element 1350 is turned on. At this time, the door using the lock body device is closed, and the square tongue 300 is unlocked. state. As the control element 1400 continues to control the operation of the driving mechanism 1000 , the driving mechanism 1000 drives the latch bolt 200 to retract through the first transmission mechanism 500 , so as to unlock the latch bolt 200 .

During the unlocking process of the latch tongue 200, the first detection element 1310 is switched from the off state to the on state, the second detection element 1320 is in the on state, the third detection element 1330 is in the off state, and the second detection element 1330 is in the off state. A group of fourth detection elements 1340 is switched from an off state to an on state, a second group of fourth detection elements 1340 is switched from an on state to an off state, and the fifth detection element 1350 remains in an on state.

In some embodiments, when the oblique tongue 200, the square tongue 300 and the sensing tongue 1200 are all retracted, the first detection element 1310 is turned on, the second detection element 1320 is turned on, the third detection element 1330 is turned off, and the second detection element 1330 is turned off. One group of fourth detecting elements 1340 is connected, the second group of fourth detecting elements 1340 is turned off, and the fifth detecting element 1350 is connected. The tongue 200 and the square tongue 300 are both in the unlocked state, and the user can open the door normally at this moment.

When the door is opened, the sensing tongue 1200 is stretched out, and the third detection element 1320 is switched from the off state to the on state. Gradually release the pressing effect on the latch tongue 200 so as to facilitate the extension of the latch tongue 200 relative to the base 100 . When the latch tongue 200 is stretched out, the first detection element 1310 is switched from the on state to the off state, after that, the lock body device waits for the next locking instruction.

It should be noted here that the latch tongue 200 can protrude from the base 100 under the elastic force of the elastic member. During the extension process of the latch tongue 200, since the driving mechanism 1000 has a certain force on the latch tongue 200 through the first transmission mechanism 500 As a barrier, under the joint action of the drive mechanism 1000 and the elastic member, the oblique tongue 200 slowly protrudes from the base 100. Compared with the way that the oblique tongue 200 of some door locks is directly ejected from the elastic member, the oblique tongue 200 in the embodiment of the present application The protruding speed of the tongue 200 is relatively slow and stable, so that the phenomenon that the latch tongue 200 hits the base 100 will not occur. On the one hand, it can reduce the noise of the latch tongue 200 locking, and on the other hand, it can effectively alleviate the impact caused by the latch tongue 200 and the base 100.
