Moreover, the lock body assembly can also be manually locked and unlocked, that is, the transmission member is manually driven to rotate relative to the lock base plate, so that the transmission member drives the lock tongue to move, but in this way, the transmission member will also exert a driving force on the driving source, which is easy to damage the driving source. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a lock body assembly that can solve the problem of easy damage to the drive source during manual locking and unlocking in the related art.

[0031] The lock body assembly provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0032] Please refer to Figure 1-Figure 7 The lock body assembly disclosed in the embodiment of the present application includes a lock base plate 100, a driving mechanism, a toggle member 400, a transmission member 500 and a lock tongue 600, wherein the lock base plate 100 serves as an installation base for the driving mechanism, the toggle member 400, the transmission member 500 and the lock tongue 600, the driving mechanism, the toggle member 400, the transmission member 500 and the lock tongue 600 are all arranged on the lock base plate 100, and the toggle member 400, the transmission member 500 and the lock tongue 600 can all move relative to the lock base plate 100; the driving mechanism is used to provide movement power for the lock tongue 600, and the transmission member 500 and the toggle member 400 serve as power transmission components of the driving mechanism.

[0033] The toggle member 400, the transmission member 500 and the lock tongue 600 can all be movably arranged on the lock base plate 100. Optionally, the toggle member 400 and the transmission member 500 can be rotatably arranged on the lock base plate 100, or the toggle member 400 and the transmission member 500 can be movably arranged on the lock base plate 100; the lock tongue 600 can be rotatably arranged on the lock base plate 100, or the lock tongue 600 can be movably arranged on the lock base plate 100. Specifically, the lock base plate 100 is provided with a lock hole. During the movement of the lock tongue 600 relative to the lock base plate 100, the lock tongue 600 extends out of the lock hole to achieve locking, or the lock tongue 600 extends into the lock hole to achieve unlocking.

[0034] The driving mechanism includes a driving source 200 and a manual driving member 300, wherein the driving source 200 can be a driving member such as a driving motor 210, a pneumatic motor, etc. that can provide rotational power. The output shaft of the driving source 200 is connected to the transmission member 500, and the transmission member 500 and the toggle member 400 are transmitted and matched in the first direction A, and the toggle member 400 is matched with the lock tongue 600. In this way, when the driving source 200 is working, it drives the transmission member 500 to move relative to the lock substrate 100, and then the transmission member 500 drives the toggle member 400 to move along the first direction A relative to the lock substrate 100, and finally the toggle member 400 drives the lock tongue 600 to move relative to the lock substrate 100 to achieve locking or unlocking.

[0035] Optionally, a mating groove 610 is provided on the side of the lock tongue 600 facing the toggle member 400, and the end of the toggle member 400 extends into the mating groove 610. During the movement of the transmission member 500, the end of the transmission member 500 acts on the groove wall of the mating groove 610, thereby driving the lock tongue 600 to move.

[0036] The manual driving member 300 is connected to the toggle member 400. Optionally, when the toggle member 400 is rotatably disposed on the lock base plate 100, the manual driving member 300 may be a knob or other component that can be manually driven to rotate; when the toggle member 400 is movably disposed on the lock base plate 100, the manual driving member 300 may be a key or other component that can be manually driven to move. In this way, the toggle member 400 can be driven to move relative to the lock base plate 100 by the manual driving member 300 alone.

[0037] When the driving source 200 drives the transmission member 500 to move along the first direction A, the toggle member 400 moves along the first direction A relative to the lock substrate 100, and the toggle member 400 drives the lock tongue 600 to move relative to the lock substrate 100, so that the lock body assembly is in the first state.

[0038] When the lock body assembly is in the first state and the driving source 200 drives the transmission member 500 to move in the second direction B, the manual driving member 300 can drive the toggle member 400 to move in the second direction B, and the toggle member 400 drives the lock tongue 600 to move relative to the lock base plate 100, so that the lock body assembly is in the second state, and the second direction B is opposite to the first direction A. The first state is one of the locked state and the unlocked state, and the second state is the other.

[0039] Optionally, refer to Figure 1 As shown, when the driving source 200 drives the transmission member 500 to move in the first direction A (i.e., counterclockwise), the transmission member 500 drives the toggle member 400 to move in the first direction A (i.e., counterclockwise) relative to the lock substrate 100, and the toggle member 400 drives the lock tongue 600 to move in the first direction A (i.e., counterclockwise) relative to the lock substrate 100. Figure 1 The lock body assembly is locked by moving the lock tongue 600 in the X direction. This is the process of automatic locking by the driving source 200.

[0040] When the lock assembly is in the locked state, the driving source 200 drives the transmission member 500 to move in the second direction B (i.e. Figure 2 When the toggle member 400 moves in the clockwise direction (in the second direction B), the toggle member 400 loses the blocking effect of the transmission member 500, and the manual driving member 300 can drive the toggle member 400 to move in the second direction B (i.e. Figure 2 The transmission member 500 will not be affected by the toggle member 400, and the toggle member 400 drives the lock tongue 600 to move relative to the lock substrate 100 along the Figure 2 The lock body assembly is in an unlocked state by moving in the X direction in the lock body 600. This is a process of manually unlocking by the manual drive member 300.

[0041] Similarly, refer to Figure 3 As shown, when the driving source 200 drives the transmission member 500 to move along the first direction A (i.e., clockwise), the transmission member 500 drives the toggle member 400 to move along the first direction A (i.e., clockwise) relative to the lock substrate 100, and the toggle member 400 drives the lock tongue 600 to move along the first direction A (i.e., clockwise) relative to the lock substrate 100. Figure 3 The lock body assembly is in an unlocked state by moving in the X direction in the lock body 600, and the lock tongue 600 extends out of the lock hole. This is the process of realizing automatic unlocking by the driving source 200.

[0042] When the lock assembly is in the unlocked state, and the driving source 200 drives the transmission member 500 to move in the second direction B (i.e. Figure 4 When the toggle member 400 moves in the counterclockwise direction (in the second direction B), the toggle member 400 loses the blocking effect of the transmission member 500, and the manual driving member 300 can drive the toggle member 400 to move in the second direction B (i.e. Figure 4The transmission member 500 will not be affected by the toggle member 400, and the toggle member 400 drives the lock tongue 600 to move relative to the lock substrate 100 along the Figure 4 The lock body assembly is locked by the manual drive member 300.

[0043] In the embodiment of the present application, the driving source 200 is utilized to drive the transmission member 500 and the toggle member 400 to move in the first direction A, thereby driving the lock tongue 600 to move relative to the lock substrate 100, so that the lock body assembly is in the first state, and further drives the transmission member 500 to move in the opposite direction, so that the transmission member 500 makes way for the manual driving member 300 to drive the toggle member 400 in the process of making space, and avoids the manual driving member 300 driving the toggle member 400 to move in the second direction B and affecting the driving source 200 through the transmission member 500. Therefore, the manual driving member 300 can smoothly drive the toggle member 400 to drive the lock tongue 600 to move, so as to switch the state of the lock body assembly, and will not apply a reverse driving force to the driving source 200, so that the driving source 200 is not easily damaged.

[0044] In an optional embodiment, the toggle member 400 and the transmission member 500 are rotatably disposed on the lock base plate 100, and the transmission member 500 is provided with a first limiting structure 511, and the first limiting structure 511 cooperates with the toggle member 400 to limit the position in the first rotation direction, and the first rotation direction is the first direction A. In this way, the manual driving member 300 can only drive the toggle member 400 to rotate in the reverse direction of the first rotation direction, and then the toggle member 400 drives the lock tongue 600 to move, so as to switch the state of the lock body assembly.

[0045] In another embodiment, the transmission member 500 is further provided with a second limiting structure 512, and the second limiting structure 512 cooperates with the toggle member 400 to limit the position in the second rotation direction, the first direction A is one of the first rotation direction and the second rotation direction, and the second direction B is the other. Optionally, the first limiting structure 511 and the second limiting structure 512 can be limiting protrusions, or two end walls of a limiting groove, and the embodiment of the present application does not limit the specific structure of the first limiting structure 511 and the second limiting structure 512. Moreover, the manual driving member 300 can drive the toggle member 400 to move between the first limiting structure 511 and the second limiting structure 512, so that the manual driving member 300 can drive the toggle member 400 to move along the first rotation direction, and can also drive the toggle member 400 to move along the second rotation direction.

[0046] With this embodiment, the manual drive member 300 can drive the toggle member 400 in different directions to drive the lock tongue 600 to move so as to switch the state of the lock body assembly. The lock tongue 600 can be manually driven to unlock or to lock. In the process of manual locking or unlocking, the drive source 200 will not be affected, thereby ensuring the safety performance of the drive source 200.

[0047] In a further embodiment, Figure 1 As shown, the transmission member 500 is provided with a connected opening and an arc-shaped groove 510, the toggle member 400 passes through the opening and is connected to the manual driving member 300, and in the circumferential direction of the transmission member 500, the two end walls of the arc-shaped groove 510 are respectively the first limiting structure 511 and the second limiting structure 512, and the two end walls of the arc-shaped groove 510 are respectively the first end wall and the second end wall. Specifically, in the process of the manual driving member 300 driving the toggle member 400 to move along the first rotation direction, the toggle member 400 is limitedly matched with the first end wall of the arc-shaped groove 510; in the process of the manual driving member 300 driving the toggle member 400 to move along the second rotation direction, the toggle member 400 is limitedly matched with the second end wall of the arc-shaped groove 510.

[0048] Optionally, the lock substrate 100 is provided with a through hole, which is opposite to the opening, the toggle member 400 and the transmission member 500 are located on the first side of the lock substrate 100, the manual driving member 300 is located on the second side of the lock substrate 100, and the toggle member 400 passes through the opening and the through hole in sequence and is connected to the manual driving member 300.

[0049] According to this embodiment, the transmission member 500 is directly provided with an arc-shaped slot 510 to form a first limiting structure 511 and a second limiting structure 512, and there is no need to separately provide at least two limiting protrusions and other complex structures, which is conducive to simplifying the structure.

[0050] In the solution of the present application, the lock body assembly further includes a first detection device, the first detection device is used to detect the position of the transmission member 500 moving along the second direction B, the first detection device is connected to the driving source 200 in communication, and when the first detection device detects that the transmission member 500 moves to the first limit position along the second direction B, the driving source 200 stops working, and the transmission member 500 stays at the first limit position. Optionally, the first detection device can be a first position sensor, and the first position sensor is used to directly detect the moving position of the transmission member 500; the first detection device can also include a first transmitter, a first receiver and a first baffle, the first transmitter transmits a laser signal, the first receiver is used to receive the laser signal, the first transmitter and the first receiver are arranged on the lock substrate 100, and the first baffle is arranged on the transmission member 500, when the transmission member 500 moves to the first limit position along the second direction B, the first baffle is located between the first transmitter and the first receiver, and the first baffle blocks the first receiver from receiving the signal; the first detection device can also detect the moving position of the transmission member 500 in the second direction B in other ways.

[0051] It should be noted that the first extreme position refers to the position where the transmission member 500 moves along the second direction B to contact the toggle member 400 .

[0052] In this embodiment, the first detection device detects the position of the transmission member 500 moving in the second direction B to accurately control the timing of stopping the driving source 200, thereby preventing the transmission member 500 from excessively moving in the second direction B and affecting the toggle member 400.

[0053] Of course, in other embodiments, the lock body assembly may not be provided with the first detection device, and the working time of the driving source 200 may be directly controlled to determine the timing for the transmission member 500 to stop moving in the first direction A.

[0054] In an optional embodiment, the first detection device includes a detection member 700 and a first contact switch 810, and the detection member 700 is in transmission connection with the transmission member 500, so when the driving source 200 drives the transmission member 500 to move, the transmission member 500 will drive the detection member 700 to move; and the detection member 700 is provided with a first protrusion 710, so the first protrusion 710 moves with the detection member 700, and the lock body assembly also includes a circuit board 800, the circuit board 800 is arranged on the lock substrate 100, and the first contact switch 810 is arranged on the circuit board 800, and the first contact switch 810 is in communication connection with the driving source 200. When the detection device detects that the transmission member 500 moves to the first extreme position along the second direction B, the first protrusion 710 contacts the first contact switch 810, and the driving source 200 stops working. Optionally, the first contact switch 810 can be a photoelectric switch, and of course, it can also be other control switches that can be triggered by the first protrusion 710 to change the switch state, thereby changing the working state of the driving source 200.

[0055] The movement position of the first protrusion 710 represents the movement position of the transmission member 500 along the second direction B. The first contact switch 810 cooperates with the first protrusion 710 to accurately detect whether the transmission member 500 moves along the second direction B to the first extreme position, thereby ensuring that sufficient space is provided for the manually driven toggle member 400 to move along the second direction B, thereby preventing the transmission member 500 from affecting the toggle member 400.

[0056] Optionally, the lock body assembly may further include a controller, which is respectively connected to the first contact switch 810 and the driving source 200 for communication. When the first protrusion 710 contacts the first contact switch 810 , the controller controls the driving source 200 to stop working.

[0057] In a further embodiment, the driving source 200 includes a driving motor 210 and a first gear 220, the first gear 220 is sleeved on the outside of the output shaft of the driving motor 210, the transmission member 500 includes a second gear 500a, the second gear 500a is meshed with the first gear 220, and the detection member 700 is a detection gear, the detection gear is meshed with the second gear 500a. In this way, when the driving motor 210 is working, the first gear 220 rotates, the first gear 220 drives the second gear 500a to rotate, and then the second gear 500a drives the detection gear to rotate, therefore, the rotation position of the detection gear can represent the rotation position of the second gear 500a, and then cooperate with the first contact switch 810 to accurately control the timing of stopping the driving source 200.

[0058] In the solution of the present application, the lock body assembly further includes a second detection device, which is used to detect the position of the transmission member 500 moving along the first direction A, and the second detection device is in communication connection with the driving source 200. When the second detection device detects that the transmission member 500 moves along the first direction A to the second extreme position, the driving source 200 stops working, and the transmission member 500 stays at the second extreme position.

[0059] Optionally, the second detection device can be a position sensor, which uses the position sensor to directly detect the moving position of the transmission member 500; the second detection device can also include a second transmitter, a second receiver and a second baffle, the second transmitter transmits a laser signal, the second receiver is used to receive the laser signal, the second transmitter and the second receiver are arranged on the lock substrate 100, and the baffle is arranged on the transmission member 500 or the toggle member 400. When the transmission member 500 moves along the first direction A to the second extreme position, the second baffle is located between the second transmitter and the second receiver, and the second baffle blocks the second receiver from receiving the signal; the second detection device can also use other methods to detect the moving position of the transmission member 500 in the first direction A.

[0060] It should be noted that the second extreme position refers to the position of the transmission member 500 when the lock body assembly is in a locked state or an unlocked state.

[0061] According to this embodiment, the position of the transmission member 500 moving in the first direction A is detected by the second detection device to accurately control the timing of stopping the driving source 200, thereby preventing the transmission member 500 from moving excessively in the first direction A.

[0062] Of course, in other embodiments, the lock body assembly may not be provided with the second detection device, and the working time of the driving source 200 may be directly controlled to determine the timing for the transmission member 500 to stop moving in the first direction A.

[0063] In an optional embodiment, the second detection device includes a second protrusion 410 and a second contact switch 820, the second protrusion 410 is arranged on the toggle member 400, the lock body assembly further includes a circuit board 800, the circuit board 800 is arranged on the lock substrate 100, the second contact switch 820 is arranged on the circuit board 800, the second contact switch is fixed relative to the lock substrate 100, and the second contact switch 820 is connected to the drive source 200. When the lock body assembly is in the first state, that is, when the lock body assembly is in the unlocked state or the locked state, it means that the transmission member 500 moves to the second extreme position along the first direction A, the second protrusion 410 contacts the second contact switch 820, and the drive source 200 stops working. Optionally, the second contact switch 820 can be a photoelectric switch, and of course, it can also be other control switches that can be triggered by the second protrusion 410 to change the switch state, thereby changing the working state of the drive source 200.

[0064] The movement position of the second protrusion 410 represents the movement position of the transmission member 500 along the first direction A. The second contact switch 820 cooperates with the second protrusion 410 to accurately detect whether the transmission member 500 moves along the first direction A to the second extreme position, thereby ensuring that the lock body assembly is accurately in a locked state or an unlocked state.

[0065] In an optional embodiment, the number of the second contact switch 820 is one, and when the lock body assembly is in an unlocked state or a locked state, the second protrusion 410 contacts the second contact switch 820 .

[0066] In another embodiment, in combination Figure 6 and Figure 7 As shown, the number of the second contact switches 820 is at least two, and the second contact switches 820 are arranged at intervals. When the lock body assembly is in an unlocked state, the second protrusion 410 contacts one of the second contact switches 820; when the lock body assembly is in a locked state, the second protrusion 410 contacts the other second contact switch 820.

[0067] By adopting this embodiment, at least two second contact switches 820 are set, so that the second protrusion 410 can contact different second contact switches 820 when it is in different positions, so that the driving source 200 can be accurately controlled to stop working when the lock body assembly is in an unlocked state, and the driving source 200 can be accurately controlled to stop working when the lock body assembly is in a locked state.

[0068] The first protrusion 710 and the second protrusion 410 mentioned above can both be bosses or other protrusion structures. The transmission member 500, the toggle member 400 and the detection gear are all located between the lock substrate 100 and the circuit board 800. The first protrusion 710 protrudes from the surface of the toggle member 400 facing the circuit board 800, so as to facilitate the contact between the first protrusion 710 and the first contact switch 810. The second protrusion 410 protrudes from the surface of the detection member 700 facing the circuit board 800, so as to facilitate the contact between the second protrusion 410 and the second contact switch 820.

[0069] In an optional embodiment, the lock body assembly also includes an elastic member 900, which can be but is not limited to a spring. The first end of the elastic member 900 is a fixed end, and the second end of the elastic member 900 is connected to the toggle member 400. When the driving source 200 drives the transmission member 500 to move along the second direction B and the manual driving member 300 does not act on the toggle member 400, the elastic member 900 supports the toggle member 400 by relying on the elastic force generated by the elastic member 900, so that the toggle member 400 is fixed relative to the lock substrate 100, thereby preventing the toggle member 400 from moving with the transmission member 500.

[0070] Optionally, the elastic member 900 may be a torsion spring, and a first end of the torsion spring is connected to the center of the detection gear. Figure 1 , Figure 4 and Figure 7 As shown, the toggle member 400 is provided with a protruding column 420, and the second end of the torsion spring is sleeved outside the protruding column 420. During the rotation of the toggle member 400 and the detection gear, the position of the first end of the torsion spring is fixed.
