The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 14, an embodiment of the present application discloses a lock body device, which includes a base 100, a latch bolt 200, a square bolt 300, a sensing bolt 1200, a first transmission mechanism 500, a second transmission mechanism 600, and a driving mechanism 1000.

The base 100 is a basic mounting member of the lock device, and may provide a mounting base for the latch bolt 200, the dead bolt 300, the first transmission mechanism 500, the second transmission mechanism 600, and the driving mechanism 1000. Alternatively, the base 100 may be a plate-like structure, such as a rectangular plate, etc. In addition, the base 100 may be made of a plate-shaped metal material to enhance the strength of the whole lock device.

The latch bolt 200 is a structural member that plays a role in locking in the lock device, and the latch bolt 200 is movably disposed on the base 100, so that the latch bolt 200 can extend or retract relative to the base 100 to achieve the purpose of locking or unlocking. Optionally, the latch tongue 200 has an inclined plane or an inclined arc. When the lock body device is applied to a door, the latch bolt 200 may be engaged with a slot on a door frame, and the inclined surface of the latch bolt 200 is pressed by the door frame to be retracted into the base 100 during the closing of the door. As the door continues to close until the latch 200 is aligned with the slot in the door frame, the latch 200 may extend from the base 100 and into the slot to lock the door. It should be noted here that the power for extending the latch tongue 200 can be from an elastic member, such as a spring.

The square bolt 300 is another structural member of the lock body device for locking, and the square bolt 300 is movably disposed on the base 100 and can be extended or retracted relative to the base 100. Alternatively, the tongue 300 may include a rectangular convex structure, and may have other shapes, which are not limited herein. The end of the dead bolt 300 may be provided with a plurality of protruding structures, and in the locked state, the plurality of protruding structures bear the acting force together, so that the lock device bears a larger acting force without being damaged, thereby improving the safety of the lock device.

The sensing tongue 1200 is a touch-sensitive structure in the lock device, and can be used with some sensing structures, so as to detect whether the door is closed well. The sensing tongue 1200 is movably disposed on the base 100 and can be extended or retracted relative to the base 100. When the door is closed, the sensing tongue 1200 is pressed by the doorframe and is retracted into the base 100, and when the door is opened or hidden, the sensing tongue 1200 is not pressed by the doorframe, and at this time, the sensing tongue 1200 can extend out of the base 100. It should be noted here that an elastic structure member may be disposed between the sensing tongue 1200 and the base 100, so that the sensing tongue 1200 has a movement tendency of extending out of the base 100 at any time.

The first transmission 500 is a mechanism for transmitting motion and power. In some embodiments, the first transmission mechanism 500 is rotatably disposed on the base 100, and when the first transmission mechanism 500 is driven, the first transmission mechanism 500 can rotate a certain angle relative to the base 100, so as to drive the next stage of mechanism to move. The first transmission mechanism 500 is in transmission connection with the driving mechanism 1000, and the first transmission mechanism 500 can be in contact with the latch tongue 200, so that the motion and power on the driving mechanism 1000 can be transmitted to the latch tongue 200 through the first transmission mechanism 500, thereby driving the latch tongue 200 to move relative to the base 100, so as to retract the latch tongue 200 relative to the base 100.

Optionally, the first transmission mechanism 500 may include a first transmission portion, a second transmission portion and a pushing portion 530, wherein the first transmission portion is used for connecting with the driving mechanism 1000, the second transmission portion is used for connecting with the second transmission mechanism 600 in a transmission manner, and the pushing portion 530 is used for stopping against the latch 200. In this way, when the driving mechanism 1000 drives the first transmission mechanism 500 to rotate, the pushing portion 530 may press the latch tongue 200, so that the latch tongue 200 retracts into the base 100, thereby unlocking the latch tongue 200.

The second transmission mechanism 600 is another mechanism for transmitting motion and power. In some embodiments, the second transmission mechanism 600 is rotatably disposed on the base 100, and when the second transmission mechanism 600 is driven, the second transmission mechanism 600 can rotate a certain angle relative to the base 100, so as to drive the next stage mechanism to move. The second transmission mechanism 600 is in transmission connection with the first transmission mechanism 500, and the second transmission mechanism 600 is movably connected with the tongue 300, so that the second transmission mechanism 600 can transmit motion and power to the tongue 300, thereby driving the tongue 300 to move relative to the base 100, so as to extend or retract the tongue 300 relative to the base 100.

Optionally, the second transmission mechanism 600 may include a third transmission portion and a fourth transmission portion, wherein the third transmission portion is in transmission connection with the second transmission portion, so as to realize transmission connection between the second transmission mechanism 600 and the first transmission mechanism 500.

The driving mechanism 1000 is a power source in the lock body device, and provides a driving force for unlocking or locking of the lock body device, so as to achieve automatic locking and unlocking of the lock body device. The driving mechanism 1000 is drivingly connected to the first transmission mechanism 500, such that the driving mechanism 1000 can drive the tongue 300 to extend or retract relative to the base 100 through the first transmission mechanism 500 and the second transmission mechanism 600. At the same time, the driving mechanism 1000 can also drive the latch tongue 200 to retract relative to the base 100 through the first transmission mechanism 500.

In order to realize the automatic control of the lock body device, the lock body device in the embodiment of the present application further includes a control member 1400, and a first detection member 1310, a second detection member 1320, a third detection member 1330 and a fourth detection member 1340 electrically connected to the control member 1400, respectively. The first detecting element 1310 is used for detecting the position state of the latch tongue 200, the second detecting element 1320 is used for detecting the position state of the tongue 300, the third detecting element 1330 is used for detecting the position state of the sensing tongue 1200, and the fourth detecting element 1340 is used for detecting the position of the first transmission mechanism 500. Alternatively, the first detecting element 1310, the second detecting element 1320, the third detecting element 1330 and the fourth detecting element 1340 may be electronic detecting components, such as position sensors, etc., and the four detecting elements are electrically connected to the control element 1400, so that the four detecting elements can respectively send their respective detection results to the control element 1400 for analysis and judgment by the control element 1400.

The control element 1400 can control the driving mechanism 1000 to operate according to the detection results of the first detecting element 1310, the second detecting element 1320, the third detecting element 1330 and the fourth detecting element 1340, so that the driving mechanism 1000 drives the latch tongue 200 to move through the first transmission mechanism 500, or drives the latch tongue 300 to move through the first transmission mechanism 500 and the second transmission mechanism 600. Besides, the control unit 1400 may determine that the door using the lock device is in an open or closed state according to the position information of the sensing tongue 1200, and control the operation of the latch bolt 200 and the dead bolt 300 according to the state of the sensing tongue 1200. Based on the above arrangement, the lock body device in the embodiment of the present application can implement various control logics, for example, control the latch bolt 200 to unlock, control the dead bolt 300 to unlock and lock, and control the latch bolt 200 and the dead bolt 300 according to the state of the sensing bolt 1200, so that the lock body state is more powerful. Meanwhile, the lock body device in the embodiment of the application also has higher control precision, so that the latch bolt 200 and the dead bolt 300 can be extended or retracted timely, and the high-efficiency operation of the lock body device is ensured.

In the embodiment of the present application, in the case that the lock body device is applied to a door, when the door is in an open state, the latch bolt 200 is extended, the dead bolt 300 is retracted, and the sensing bolt 1200 is extended; when the door is in a fully locked state, the latch bolt 200 extends out, the dead bolt 300 extends out, and the sensing bolt 1200 retracts; when the door is in the state that the dead bolt 300 is locked, the latch bolt 200 retracts, the dead bolt 300 extends, and the sensing bolt 1200 retracts; when the door is completely unlocked and closed, the latch bolt 200 retracts, the dead bolt 300 retracts, and the sensing bolt 1200 retracts; when the door is in a fully unlocked and opened state, the latch bolt 200 retracts, the dead bolt 300 retracts, and the sensing bolt 1200 extends.

In some embodiments, the lock body device includes two sets of fourth detecting elements 1340, the first transmission mechanism 500 has a first detecting portion 513, the first detecting portion 513 is disposed corresponding to the first set of fourth detecting elements 1340 in the case that the latch bolt 200 and the sensing bolt 1200 are both extended, and the first detecting portion 513 is disposed corresponding to the second set of fourth detecting elements 1340 in the case that the latch bolt 200, the dead bolt 300 and the sensing bolt 1200 are all retracted. Alternatively, the first detecting portion 513 may be a stopper protruding from the first transmission mechanism 500, and when the first detecting portion 513 is disposed corresponding to the fourth detecting element 1340, the first detecting portion 513 blocks a detecting portion of the fourth detecting element 1340, so that the fourth detecting element 1340 is turned off. In an embodiment, the fourth detecting element 1340 is a photoelectric switch, when the first detecting portion 513 moves to a position corresponding to the fourth detecting element 1340, the first detecting portion 513 blocks light, and at this time, the fourth detecting element 1340 can determine that the first detecting portion 513 is located at the position, so as to obtain the rotation position information of the first transmission mechanism 500.

Based on the above arrangement, when the door using the lock body device is opened, the latch bolt 200 and the sensing bolt 1200 are both extended, and the square bolt 300 is retracted, so that the first detection part 513 on the first transmission mechanism 500 is located at the position of the first group of the fourth detection elements 1340 in the above case. When the door is closed and the latch tongue 200 and the latch tongue 300 are unlocked, the latch tongue 200, the latch tongue 300 and the sensing tongue 1200 are all retracted, and the first detection part 513 on the first transmission mechanism 500 is located at the position of the second group 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 sets of fourth detection elements 1340, and the position information of the oblique tongue 200 or the square tongue 300 can be further determined.

In some embodiments, the lock body device further includes a fifth detecting element 1350 for detecting the lock-out condition of the square bolt 300, and accordingly, the second transmission mechanism 600 has a second detecting portion 612, and the second detecting portion 612 is disposed corresponding to the fifth detecting element 1350 when the square bolt 300 is extended. Alternatively, the second detecting portion 612 may be a stopper protruding from the second transmission mechanism 600, and when the second detecting portion 612 is disposed corresponding to the fifth detecting element 1350, the second detecting portion 612 blocks the detecting portion of the fifth detecting element 1350, so that the fifth detecting element 1350 is disconnected. In an embodiment, the fifth detecting element 1350 is a photoelectric switch, and when the second detecting portion 612 moves to a position corresponding to the fifth detecting element 1350, the second detecting portion 612 blocks light, and it can be determined that the second detecting portion 612 is located at the position, so as to obtain the rotation position information of the second transmission mechanism 600.

With the above arrangement, in the case where the door to which the lock body device is applied is closed and the lock body device is completely locked, both the latch bolt 200 and the dead bolt 300 are extended, and the sensing bolt 1200 is retracted, whereby the second sensing part 612 of the second driving mechanism 600 is located at the position of the fifth sensing element 1350 in the above case. 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 bolt 300 is completely locked.

In some embodiments, when the latch tongue 200 and the sensing tongue 1200 are extended and the square tongue 300 is retracted, the first detecting element 1310 is turned off, the second detecting element 1320 is turned on, the third detecting element 1330 is turned on, the first group of the fourth detecting elements 1340 is turned off, the second group of the fourth detecting elements 1340 is turned on, and the fifth detecting element 1350 is turned on, the door using the lock body device is in an open state. In this state, the user can actuate the door to close, and as the door is closed, the latch 200 touches the door frame and retracts into the base 100, so that the first detecting element 1310 is switched from the off state to the on state; at the same time, the sensing tongue 1200 also touches the door frame and retracts into the base 100, so that the third detecting element 1330 is switched from the on state to the off state. When the door is completely closed, the latch tongue 200 is extended again, so that the first detecting element 1310 is switched from the on state to the off state again. During the door closing process, the second detecting element 1320 is in an on state, the first group of the fourth detecting elements 1340 is in an off state, the second group of the fourth detecting elements 1340 is in an on state, and the fifth detecting element 1350 is in an on state.

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 that the door is normally closed, and then after a short time (e.g., 3 seconds and the like), the control element 1400 controls the driving 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 extend relative to the base 100, so that the square tongue 300 is locked.

Since the second transmission mechanism 600 rotates to drive the square tongue 300 to be locked, the second detection part 612 rotates along with the second transmission mechanism 600 in the process, when the square tongue 300 is locked, the second detection part 612 just rotates to the position of the fifth detection element 1350, and the fifth detection element 1350 is disconnected, so that the fifth detection element 1350 can detect the second detection part 612, and the detection result is sent to the control element 1400, thereby determining that the square tongue 300 is normally locked.

In some embodiments, when the latch bolt 200 and the dead bolt 300 are extended and the sensing bolt 1200 is retracted, the first detecting element 1310 is turned off, the second detecting element 1320 is turned off, the third detecting element 1330 is turned off, the two sets of the fourth detecting elements 1340 are respectively turned on, and the fifth detecting element 1350 is turned off, at which time, the door to which the lock body device is applied is in a closed state, and the lock body device is completely locked. Then, the user can input unlocking information, such as a fingerprint, a card swipe and the like, the control element 1400 receives the unlocking information input by the user and controls the driving mechanism 1000 to start, and the driving mechanism 1000 sequentially drives the tongue 300 to retract relative to the base 100 through the first transmission mechanism 500 and the second transmission mechanism 600, so as to unlock the tongue 300. Meanwhile, after receiving the unlocking information input by the user, the control element 1400 controls the driving mechanism 1000 to start, and the driving mechanism 1000 may further 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 that, during the unlocking process, the square tongue 300 and the oblique tongue 200 can be unlocked simultaneously under the driving action of the driving mechanism 1000.

In the case where neither the square tongue 300 nor the oblique tongue 200 is unlocked, the first detection part 513 is located on a side of the first group of fourth detection elements 1340 facing away from the second group of fourth detection elements 1340, and the second detection part 612 is disposed opposite to the fifth detection elements 1350; when the tongue 300 and the latch 200 are completely unlocked, the first detecting portion 513 is rotated to a position opposite to the first group of the fourth detecting elements 1340, and the second detecting portion 612 is separated from the fifth detecting elements 1350, and at the same time, in the process of unlocking the tongue 300 and the latch 200, the first detecting element 1310 is switched from the off state to the on state, the second detecting element 1320 is switched from the off state to the on state, and the third detecting element 1330 is not changed in the off state.

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

During the process of unlocking the latch 200, the first detecting element 1310 is switched from the off state to the on state, the second detecting element 1320 is unchanged from the on state, the third detecting element 1330 is unchanged from the off state, the first group of the fourth detecting elements 1340 is switched from the off state to the on state, the second group of the fourth detecting elements 1340 is switched from the on state to the off state, and the fifth detecting element 1350 is unchanged from the on state.

In some embodiments, when the latch tongue 200, the latch tongue 300 and the sensing tongue 1200 are all retracted, the first detecting element 1310 is turned on, the second detecting element 1320 is turned on, the third detecting element 1330 is turned off, the first group of the fourth detecting elements 1340 is turned on, the second group of the fourth detecting elements 1340 is turned off, and the fifth detecting element 1350 is turned on, the door to which the lock body device is applied is in a completely unlocked state, that is, the latch tongue 200 and the latch tongue 300 are both in an unlocked state, and the user can open the door normally.

When the door is opened, the sensing tongue 1200 is extended, and the third detecting element 1330 is switched from the off state to the on state, based on which the control element 1400 controls the driving mechanism 1000 to start again, and the driving mechanism 1000 gradually releases the squeezing action on the latch tongue 200 through the first transmission mechanism 500, so as to facilitate the extension of the latch tongue 300 relative to the base 100. When the latch bolt 200 is extended, the first detecting element 1310 is switched from the on state to the off state, so that the unlocking process of the lock body device is realized, and thereafter, the lock body device waits for a next lock falling instruction.

It should be noted here that the latch bolt 200 may extend out of the base 100 under the elastic force of the elastic member, and in the process of extending the latch bolt 200, because the driving mechanism 1000 has a certain barrier function on the latch bolt 200 through the first transmission mechanism 500, under the combined action of the driving mechanism 1000 and the elastic member, the latch bolt 200 slowly extends out of the base 100, compared with the manner that the latch bolt 200 of some door locks is directly ejected by the elastic member, the extending speed of the latch bolt 200 in the embodiment of the present application is slow and stable, so that the phenomenon that the latch bolt 200 impacts the base 100 does not occur, on one hand, the noise that the latch bolt 200 falls off the lock can be reduced, and on the other hand, the problem that parts are damaged due to the impact of the latch bolt 200 and the base 100 can be effectively alleviated.

In addition, in consideration that the extension process of the latch tongue 200 does not cause the movement of the latch tongue 300, the first transmission mechanism 500 in the embodiment of the present application may include two structural members that can rotate relatively by a certain angle, one of the two structural members may drive the latch tongue 200 to move, and the other may drive the latch tongue 300 to move, so that in the extension process of the latch tongue 200, the driving mechanism 1000 drives and starts one of the structural members to rotate, and the other structural member does not rotate, so that the latch tongue 300 is not driven to move. The specific structure of the first transmission mechanism 500 will be described in detail later.

In some embodiments, the first sensing element 1310 may be a micro-switch. The micro switch has a micro contact interval and a quick action mechanism, and the contact mechanism performs switching action by using a specified stroke and a specified force, so that the fixed contact and the movable contact can be quickly connected or disconnected under the action of external mechanical force. For the specific structure and operation principle of the micro switch, reference is made to the related art, and details are not repeated here. Alternatively, the second detecting element 1320 may also be a micro switch; the third detection element 1330 may also be a micro switch.

In addition, the fourth detection element 1340 may be a photo switch. The photoelectric switch utilizes the shielding or reflection of the detected object to the light beam to switch on the circuit by the synchronous circuit, thereby detecting the existence of the object. Alternatively, the fifth detecting element 1350 may be a photoelectric switch, and the second detecting portion 612 blocks light when passing through the fifth detecting element 1350, so as to determine the position of the second detecting portion 612.

In some embodiments, the first detecting element 1310 is disposed on a region of the base 100 adjacent to the latch tongue 200, the first detecting element 1310 includes a first contact piece, the latch tongue 200 has a first contact portion, and the first contact portion of the latch tongue 200 can abut against the first contact piece. Since the latch bolt 200 can extend or retract relative to the base 100, when the latch bolt 200 extends relative to the base 100, the first touching portion of the latch bolt 200 is separated from the first contact piece, and the movable contact end and the stationary contact end of the first detecting element 1310 are separated, so that the first detecting element 1310 is disconnected, and the first detecting element 1310 sends a disconnected signal to the control element 1400, so as to determine that the latch bolt 200 is in the extended state, so that the control element 1400 of the lock body device knows the specific position of the latch bolt 200. Under the condition that the latch bolt 200 retracts relative to the base 100, the first touch end of the latch bolt 200 presses the first contact piece, at this time, the movable contact end and the stationary contact end of the first detection element 1310 contact with each other, so that the first detection element 1310 is switched on, at this time, the first detection element 1310 sends a switching-on signal to the control element 1400, and therefore, the latch bolt 200 is determined to be in a retraction state, so that the control element 1400 of the lock body device knows the specific position of the latch bolt 200. It should be noted that, the specific structure of the first detecting element 1310 and the operation principle thereof can also refer to the related art, and are not described herein again.

Similarly, the second detecting element 1320 is disposed in a region of the base 100 adjacent to the square tongue 300, the second detecting element 1320 includes a second contact piece, a rear end surface of the square tongue 300 is a second contact portion, and the second contact portion of the square tongue 300 can be abutted against the second contact piece. Since the square tongue 300 can extend or retract relative to the base 100, when the square tongue 300 extends relative to the base 100, the second touching portion of the square tongue 300 is separated from the second contact piece, and the movable contact end and the stationary contact end of the second detecting element 1320 are separated, so that the second detecting element 1320 is disconnected, and the second detecting element 1320 sends a disconnected signal to the control element 1400, so that the square tongue 300 is determined to be in the extended state, and the control element 1400 of the lock body device knows the specific position of the square tongue 300. When the dead bolt 300 retracts relative to the base 100, the second touching portion of the dead bolt 300 presses the second contact piece, and at this time, the movable contact end and the stationary contact end of the second detecting element 1320 contact each other, so that the second detecting element 1320 is turned on, and at this time, the second detecting element 1320 sends a turned-on signal to the control element 1400, so that it is determined that the dead bolt 300 is in a retracted state, and the control element 1400 of the lock body device knows the specific position of the dead bolt 300. It should be noted that, for the specific structure of the second detecting element 1320 and the operation principle thereof, reference may also be made to the related art, and details are not described herein.

Similarly, the third detecting element 1330 is disposed in a region of the base 100 adjacent to the sensing tongue 1200, the third detecting element 1330 includes a third contact piece, the sensing tongue 1200 has a third touching portion, and the third touching portion of the sensing tongue 1200 can be abutted against the third contact piece. Since the sensing tongue 1200 can extend or retract relative to the base 100, when the sensing tongue 1200 extends relative to the base 100, the third touching portion of the sensing tongue 1200 presses the third contact piece, and the movable contact end and the stationary contact end of the third detection element 1330 contact each other at this time, so that the third detection element 1330 is turned on, and at this time, the third detection element 1330 sends a turn-on signal to the control element 1400, thereby determining that the sensing tongue 1200 is in the extended state, and making the control element 1400 of the lock body device know the specific position of the sensing tongue 1200. When the sensing tongue 1200 retracts relative to the base 100, the third touch end of the sensing tongue 1200 is separated from the third contact piece, and at this time, the movable contact end and the stationary contact end of the third detecting element 1330 are separated, so that the third detecting element 1330 is disconnected, and at this time, the third detecting element 1330 sends a disconnected signal to the control element 1400, so that it is determined that the sensing tongue 1200 is in a retraction state, and the control element 1400 of the lock body device knows the specific position of the sensing tongue 1200. It should be noted that, the specific structure of the third detecting element 1330 and the operation principle thereof may also refer to the related art, and are not described herein again.

In some embodiments, two sets of the fourth detecting elements 1340 are spaced apart from each other on the region of the base 100 adjacent to the first actuator 500, and the fourth detecting elements 1340 include a light emitting end and a light receiving end. During the rotation of the first transmission mechanism 500, the first detection portion 513 may pass through the two sets of fourth detection elements 1340, at this time, the first detection portion 513 may block the light between the light emitting end and the light receiving end, so as to turn off the fourth detection elements 1340, at this time, the fourth detection elements 1340 may send a signal of turning off to the control element 1400, thereby determining the rotation position of the first transmission mechanism 500, and determining the specific positions of the latch tongue 200 and the latch tongue 300 according to the rotation position of the first transmission mechanism 500. It should be noted that, for the specific structure of the fourth detecting element 1340 and the working principle thereof, reference may also be made to related technologies, and details are not described herein.

Similarly, the fifth detecting element 1350 is disposed on the region of the base 100 adjacent to the second driving mechanism 600, and the fifth detecting element 1350 comprises a light emitting end and a light receiving end. During the rotation of the second transmission mechanism 600, the second detecting portion 612 may pass through the fifth detecting element 1350, and at this time, the second detecting portion 612 blocks the light between the light emitting end and the light receiving end, so that the fifth detecting element 1350 is turned off, and at this time, the fifth detecting element 1350 sends a turn-off signal to the control element 1400, so as to determine the rotation position of the second transmission mechanism 600, and determine whether the square tongue 300 is completely extended according to the rotation position of the second transmission mechanism 600. It should be noted that, for the specific structure of the fifth detecting element 1350 and the operation principle thereof, reference may also be made to the related art, and details are not described herein.

In some embodiments, the first detecting element 1310, the second detecting element 1320, the third detecting element 1330, the fourth detecting element 1340, the fifth detecting element 1350 and the control element 1400 are disposed on the circuit board by using a PCBA process. The PCBA is the whole manufacturing process of the PCB blank board through SMT loading or DIP plug-in components. Through the manufacturing method, the electronic components can be arranged on the circuit board, so that the detection in the lock body device and the efficient operation of a control system can be guaranteed. It should be noted that, with regard to the specific manner of fabricating the PCBA, reference may be made to the related art, and therefore, the detailed description thereof is omitted.

Referring to fig. 10 to 13, in some embodiments, the first transmission mechanism 500 includes a first transmission member 510 and a second transmission member 520 respectively rotatably disposed on the base 100, wherein the first transmission member 510 is in transmission connection with the driving mechanism 1000, and the first transmission mechanism 500 can contact with the latch 200 to drive the latch 200 to retract relative to the base 100. Alternatively, the first transmission member 510 and the second transmission member 520 may be coaxially disposed, but of course, they may be separately disposed. Based on the above arrangement, when the driving mechanism 1000 drives the first transmission member 510 to rotate, the first transmission member 510 rotates to a certain angle and then touches the latch bolt 200, so that the latch bolt 200 can retract into the base 100, and the latch bolt 200 is unlocked.

Referring to fig. 6 to 9, the second transmission mechanism 600 includes a third transmission member 610 and a fourth transmission member 620 respectively rotatably disposed on the base 100, and a locking member 630, wherein the third transmission member 610 is in transmission connection with the second transmission member 520, the fourth transmission member 620 is movably connected with the square tongue 300, the locking member 630 is slidably disposed on the third transmission member 610, and the third transmission member 610 and the fourth transmission member 620 are engaged or disengaged by the locking member 630. Based on the above arrangement, the first transmission mechanism 500 can transmit the motion and power output by the driving mechanism 1000 to the second transmission mechanism 600 through the second transmission member 520 and the third transmission member 610 which are in transmission connection, and then the second transmission mechanism 600 transmits the motion and power to the square tongue 300 through the fourth transmission member 620, so that the square tongue 300 extends or retracts relative to the base 100, thereby realizing the falling lock or unlocking of the square tongue 300. Upon disengagement between retaining member 630 and fourth drive member 620, fourth drive member 620 can rotate independently relative to base 100 without rotating third drive member 610. When the locking member 630 and the fourth transmission member 620 are engaged with each other, the fourth transmission member 620 and the third transmission member 610 are rotated in synchronization to perform the motion and the power transmission.

In order to realize the engagement or disengagement between the third transmission member 610 and the fourth transmission member 620, in the embodiment of the present application, a locking protrusion 631 is disposed on one of the locking member 630 and the fourth transmission member 620, and a locking slot 622 is disposed on the other of the locking member 630 and the fourth transmission member 620, and the locking protrusion 631 and the locking slot 622 have an engagement state and a disengagement state, in which the third transmission member 610 and the fourth transmission member 620 can rotate synchronously, and in which the third transmission member 610 and the fourth transmission member 620 can rotate respectively. Optionally, a locking member 630 is positioned between the third transmission member 610 and the fourth transmission member 620 such that the projection 631 is positioned toward the fourth transmission member 620, thereby ensuring that the projection 631 can slide into and out of the slot 622 when the locking member 630 is slid relative to the third transmission member 610.

Referring to fig. 6, in order to rotate the third transmission member 610 and the fourth transmission member 620 relatively, a space-avoiding groove 623 is formed in the third transmission member 610, and the space-avoiding groove 623 communicates with the engaging groove 622. Thus, after the convex card 631 is separated from the engaging slot 622, the convex card 631 can enter the avoiding groove 623 and can move in the avoiding groove 623, thereby effectively preventing the influence on the relative rotation caused by the convex card 631 when the third transmission member 610 and the fourth transmission member 620 rotate relative to each other.

Based on the above arrangement, under the condition that the locking protrusion 631 is in clamping fit with the locking groove 622, the third transmission member 610 and the fourth transmission member 620 are locked by the locking member 630, so that the third transmission member 610 and the fourth transmission member 620 can synchronously rotate. Under the condition that the clamping protrusion 631 is separated from the clamping groove 622, the clamping protrusion 631 enters the avoiding groove 623 and can move in the avoiding groove 623, so that when the fourth transmission member 620 rotates, the third transmission member 610 cannot rotate, and motion and power cannot be transmitted between the fourth transmission member 620 and the third transmission member 610, at the moment, the driving portion 710 can independently drive the fourth transmission member 620 to rotate, and the fourth transmission member 620 drives the square tongue 300 to retract into the base 100, so that the lock body device can be easily unlocked when at least one of the driving mechanism 1000 and the first transmission mechanism 500 fails, and movable structural members are fewer in the process of unlocking the square tongue 300, so that unlocking difficulty and unlocking noise can be reduced to a certain extent.

Referring to fig. 8, in order to ensure that the locking member 630 can be automatically returned, in the embodiment of the present application, a first elastic member 810 is disposed between the locking member 630 and the third transmission member 610, the first elastic member 810 connects the locking member 630 and the third transmission member 610, and the first elastic member 810 is configured to drive the locking member 630 to move relative to the third transmission member 610, so that the catching protrusion 631 is engaged with the catching groove 622. Alternatively, the first elastic member 810 may be a spring.

Referring to fig. 1, 10 and 11, in order to achieve a stable transmission connection between the first transmission mechanism 500 and the driving mechanism 1000, in the embodiment of the present application, the first transmission member 510 includes a first tooth structure 511. Alternatively, the first tooth structure 511 may be a half tooth structure. Accordingly, the driving mechanism 1000 includes a driving gear 1010, and the driving gear 1010 is engaged with the first tooth structure 511, so that the rotation of the first transmission member 510, and thus the rotation of the first transmission mechanism 500, can be realized through the engagement of the driving gear 1010 and the first tooth structure 511.

In order to achieve stable transmission motion between the first transmission mechanism 500 and the second transmission mechanism 600, in the embodiment of the present application, the second transmission member 520 includes a second tooth structure 521, and accordingly, the third transmission member 610 includes a third tooth structure 611, and the second tooth structure 521 is in meshing connection with the third tooth structure 611. Based on the above arrangement, the first transmission mechanism 500 and the second transmission mechanism 600 are in transmission connection through the second tooth-shaped structure 521 and the third tooth-shaped structure 611 which are meshed with each other, so that power and motion transmission is realized, and meanwhile, the stability of the power and motion transmission process is ensured. Alternatively, the second tooth-shaped structure 521 and the third tooth-shaped structure 611 may be both half-tooth-shaped structures, so that the relative rotation range between the first transmission mechanism 500 and the second transmission mechanism 600 may be limited, and thus, in the case that the second transmission mechanism 600 does not rotate after the dead bolt 300 is completely retracted, the first transmission mechanism 500 may continue to rotate to drive the latch bolt 200 to retract.

With continued reference to fig. 10, in some embodiments, the first transmission member 510 is coaxially disposed with the second transmission member 520 such that both are rotatable about a common axis relative to the base 100. One of the first transmission member 510 and the second transmission member 520 is provided with a first limiting groove 522, the other one is provided with a first limiting protrusion 512, and the first limiting protrusion 512 is movably disposed in the first limiting groove 522. Optionally, the length of the first limiting groove 522 is greater than the width of the first limiting protrusion 512, so that the first limiting protrusion 512 can move a certain distance in the first limiting groove 522, and the first transmission member 510 and the second transmission member 520 can rotate relative to each other by a certain angle. Based on the above arrangement, when the first limiting protrusion 512 does not touch the end of the first limiting groove 522, the first transmission piece 510 can rotate relative to the second transmission piece 520, so that the driving mechanism 1000 can be effectively prevented from reversely rotating to accidentally cause the movement of the structural members such as the square tongue 300; when the first position-limiting protrusion 512 contacts with the end of the first position-limiting groove 522, the first transmission member 510 and the second transmission member 520 rotate synchronously to transmit the power output by the driving mechanism 1000 to the tongue 300 through the first transmission mechanism 500 and the second transmission mechanism 600, so as to extend or retract the tongue 300 relative to the base 100.

Referring to fig. 4 to 7, in some embodiments, a first guide post 621 is disposed on the fourth transmission member 620, a first guide slot 310 is disposed on the tongue 300, the first guide post 621 is movably disposed in the first guide slot 310, and the first guide post 621 can press two opposite sidewalls of the first guide slot 310 to extend or retract the tongue 300 relative to the base 100.

Based on the above arrangement, when the fourth transmission member 620 is forced to rotate relative to the base 100, the first guide pillar 621 can transmit power and motion to the first guide groove 310, so as to drive the movement of the tongue 300. Specifically, when the fourth transmission member 620 rotates in the first direction (clockwise), the first guide post 621 abuts against the first side of the first guide groove 310, so that the tongue 300 can extend relative to the base 100. In this case, the first side is disposed on a side of the square tongue 300 near the front end, and since the first guide post 621 rotates relative to the base 100, the square tongue 300 moves linearly relative to the base 100, so that the first side is designed to be an arc-shaped surface to meet the motion requirement and prevent motion interference. Conversely, when the fourth transmission member 620 rotates in a second direction (counterclockwise direction) opposite to the first direction, the first guide post 621 abuts against the second side of the first guide slot 310, so that the latch 300 can be retracted relative to the base 100. In this case, the second side is disposed on the side of the square tongue 300 away from the front end, and the square tongue 300 moves linearly relative to the base 100 due to the rotation of the first guide post 621 relative to the base 100, so that the second side is designed to be an arc-shaped surface to meet the motion requirement and prevent the motion interference.

Referring to fig. 7, in some embodiments, the lock body device further includes a key cylinder 700 rotatably disposed on the base 100, the key cylinder 700 has a driving portion 710, and the driving portion 710 can abut against the locking member 630 or the fourth transmission member 620. Alternatively, the driving portion 710 may be an eccentric rotator, such as a cam, etc. The user inserts a key into the key cylinder 700 and screws it, turning the driver 710. During the rotation of the driving part 710, the locking member 630 or the fourth transmission member 620 may be touched, thereby moving the locking member 630 or the fourth transmission member 620. Specifically, the driving portion 710 first touches the locking member 630 to release the engagement between the locking member 630 and the fourth transmission member 620, and then touches the fourth transmission member 620 to rotate the fourth transmission member 620 with the continuous rotation of the driving portion 710, so that the fourth transmission member 620 drives the tongue 300 to retract into the base 100, thereby unlocking the tongue 300. Of course, the driving portion 710 can also drive the fourth transmission member 620 to rotate reversely, and the fourth transmission member 620 moves the square bolt 300 to extend out of the base 100 and correspondingly into the door frame, so as to lock the square bolt 300. In this manner, the deadbolt 300 may be unlocked or locked by a key.

Referring to fig. 1 and 2, in some embodiments, the lock device further includes a fifth driving member 910 rotatably disposed on the base 100, and the fifth driving member 910 includes a first connecting end and a second connecting end, and the first connecting end can abut against the latch 200. In the case that the fifth transmission member 910 rotates relative to the base 100, the latch bolt 200 may be pressed by the first connection end to retract the latch bolt 200 relative to the base 100, so as to unlock the latch bolt 200. In order to drive the fifth transmission member 910 to rotate, in the embodiment of the present application, the lock body device further includes a key cylinder 700 and a linkage member 400, the key cylinder 700 has a driving portion 710, the linkage member 400 has a third connection end and a fourth connection end, the linkage member 400 is movable relative to the base 100, the driving portion 710 can abut against the third connection end, and the fourth connection end can abut against the second connection end. Based on the above arrangement, the driving portion 710 may press the third connecting end to move the link 400, and the link 400 presses the second connecting end of the fifth transmission member 910 through the fourth connecting end, so as to rotate the fifth transmission member 910, and make the first connecting end press the latch tongue 200, so as to retract the latch tongue 200. The method specifically comprises the following steps: when a user turns the key, the driving portion 710 can be driven to rotate, the driving portion 710 drives the link 400 to move, the link 400 drives the fifth transmission member 910 to rotate, and the fifth transmission member 910 presses the latch bolt 200 through the first connection end, so that the latch bolt 200 retracts relative to the base 100, and the latch bolt 200 is unlocked.

Referring to fig. 1, 10 and 11, in some embodiments, the lock body device further includes a square driving member 1100 rotatably disposed on the base 100, the square driving member 1100 being disposed coaxially with the fifth transmission member 910; one of the square driving member 1100 and the fifth driving member 910 is provided with a second limiting groove 911, the other one is provided with a second limiting protrusion 1120, the second limiting protrusion 1120 is movably disposed in the second limiting groove 911, and the square driving member 1100 is stopped by the second limiting protrusion 1120 and the second limiting groove 911 to drive the fifth driving member 910 to rotate.

With continued reference to fig. 11, optionally, a second limit groove 911 is formed on the fifth transmission member 910, and a second limit protrusion 1120 is formed on the square driving member 1100, so that the square driving member 1100 and the fifth transmission member 910 can rotate relatively within a certain range. When the square driving member 1100 rotates clockwise, the second limiting protrusion 1120 moves along the second limiting groove 911 until the second limiting protrusion 1120 touches the end of the second limiting groove 911, at this time, the square driving member 1100 can drive the fifth driving member 910 to rotate together, and after the fifth driving member 910 rotates by a certain angle, the fifth driving member touches the latch bolt 200 and pushes the latch bolt 200 to retract relative to the base 100, so that the latch bolt 200 can be unlocked.

Referring to fig. 13 and 14, in other embodiments, the lock body device further includes a square driving member 1100 rotatably disposed on the base 100, and the square driving member 1100 is disposed coaxially with the first transmission member 510 and the second transmission member 520. The square body driving member 1100 has a pushing portion 1110, the second transmission member 520 has a blocking portion 523, and the square body driving member 1100 is stopped against the blocking portion 523 by the pushing portion 1110 to drive the second transmission member 520 to rotate. Alternatively, the square body driving member 1100 is provided with a square hole, a square rod can be inserted into the square hole, and the square body driving member 1100 can be screwed by the square rod to rotate relative to the base 100. When the square driving member 1100 rotates to a certain degree, the second transmission member 520 is driven to rotate, and the second transmission mechanism 600 is driven to rotate by the second transmission member 520, so that the extension or retraction of the tongue 300 can be realized by the square driving member 1100. Based on the above arrangement, when the square body driving member 1100 rotates relative to the base 100, the two limit ends can receive the limit action of the limit posts, thereby limiting the range of the rotation angle of the square body driving member 1100. Based on the above arrangement, in the process that the square driving member 1100 rotates (rotates clockwise) relative to the base 100, the blocking portion 523 can be pressed by the pushing portion 1110, at this time, the second transmission member 520 is driven to rotate, and the second transmission mechanism 600 is driven to rotate (rotate counterclockwise) by the engagement of the second transmission member 520 and the third transmission member 610, so that the square tongue 300 is driven to retract by the second transmission mechanism 600, and the unlocking of the square tongue 300 is realized.

It should be noted that, during the rotation of the square driving member 1100, the second transmission member 520 and the fifth transmission member 910 can be driven to rotate respectively, however, the sequence of the rotation of the second transmission member 520 and the fifth transmission member 910 can be determined according to the actual situation. When the dead bolt 300 needs to be retracted firstly, the second transmission piece 520 can be driven to rotate firstly by the square body driving piece 1100, and then the fifth transmission piece 910 is driven to rotate; when the latch bolt 200 needs to be retracted first, the square driving member 1100 can drive the fifth transmission member 910 to rotate first, and then drive the second transmission member 520 to rotate; when it is desired to retract the dead bolt 300 and the latch bolt 200 simultaneously, the second transmission member 520 and the fifth transmission member 910 can be driven to rotate simultaneously by the body driving member 1100.

In some embodiments, the beveled tongue 200 is a unidirectional beveled tongue 200. Wherein, under the condition that the door takes place to warp, can reduce the influence to the normal work of lock body device through adopting one-way latch bolt 200, and simple structure, lock fast, small in noise have better using value.
