The automatic lock body structure 100 provided by one of the embodiments of the present application comprises a shell 10, a driving motor 20, a transmission assembly 30, a push plate assembly 40, a reverse lock tongue 50, a bevel tongue 60 and a micro switch 70. The shell 10 is hollow inside; the driving motor 20 is arranged in the shell 10; the transmission assembly 30 is engaged with the driving assembly, and the driving motor 20 can drive the transmission assembly 30 to move up and down; the push plate assembly 40 is connected with the transmission assembly 30, and the transmission assembly 30 can drive the push plate assembly 40 to move up and down synchronously, the push plate assembly 40 comprises a crank arm 41; a square is connected with the push plate assembly 40, a square lock tongue abuts against the crank arm 41, and the crank arm 41 can drive the square lock tongue to move up and down synchronously, the reverse lock tongue 50 is of a magnetic structure; the bevel tongue 60 is movably arranged in the shell 10; the micro switch 70 is arranged in the shell 10 and corresponds to the position of the push plate assembly 40, and the micro switch 70 is electrically connected with the driving motor 20; wherein, after the driving motor 20 is started, the reverse lock tongue 50 can be driven to move up and down by the transmission assembly 30 and the push plate assembly, and when the push plate assembly 40 moves to abut against the micro switch 70, the micro switch 70 can control the driving motor 20 to stop rotating.

[0049] ​In the embodiment, the shell 10 is hollow inside, and the shell 10 can be used to accommodate the driving motor 20, the transmission assembly 30, the push plate assembly 40, the anti-latching tongue 50, the latch tongue 60 and the micro switch 70.

[0050] The driving motor 20 is engaged with the transmission assembly 30, and when the driving assembly is started, the driving assembly can drive the transmission assembly 30 to move (specifically, the transmission assembly 30 moves up and down, so that the transmission assembly 30 can move towards or away from the direction of the anti-latching tongue 50). The transmission assembly 30 and the push plate assembly 40 are connected to each other, and when the transmission assembly 30 moves up and down, the transmission assembly 30 can drive the push plate assembly 40 to move up and down synchronously, so that the crank arm 41 on the transmission assembly 30 moves, and the crank arm 41 abuts against the anti-latching tongue 50. When the crank arm 41 moves, the crank arm 41 can drive the anti-latching tongue 50 to move, so as to pull the anti-latching tongue 50 back, thereby preventing the door body from being locked.

[0051] When the push plate assembly 40 is moved downward by the force from the transmission assembly 30, the push plate assembly 40 can move towards the micro switch 70 to approach the micro switch 70. When the push plate assembly 40 contacts the micro switch 70, the micro switch 70 can control the driving motor 20 to stop rotating, and at this time, the transmission assembly 30 and the push plate assembly 40 no longer move, the anti-latching tongue 50 is retracted to the shell 10, and the door body can be opened without being locked.

[0052] The anti-latching tongue 50 is a magnetic structure, and when the anti-latching tongue 50 is not subjected to the magnetic attraction of the magnet in the door frame before the door is closed, the anti-latching tongue 50 remains in the shell 10; when the door is closed, the magnetic attraction is generated between the anti-latching tongue 50 and the door frame, and the anti-latching tongue 50 can automatically extend, so that the user does not need to manually lock.

[0053] In some embodiments, the transmission assembly 30 includes an engagement gear 31 and an engagement tooth plate 32; the engagement gear 31 is engaged with the output end of the driving motor 20; the engagement tooth plate 32 is engaged with the engagement gear 31; and the bottom of the engagement tooth plate 32 is connected to the push plate assembly 40.

[0054] The meshing gear 31 is engaged with the output end of the driving motor 20, meaning that the meshing gear is directly connected to the output shaft of the driving motor 20 to receive the power provided by the driving motor 20 and rotate the meshing gear 31. The meshing tooth plate 32 is engaged with the meshing gear 31, and the gear shape and position of the meshing tooth plate 32 and the meshing gear 31 are designed to allow them to be engaged with each other and transmit power. Through the rotation of the meshing gear 31, power is transmitted to the meshing tooth plate 32. The bottom of the meshing tooth plate 32 is connected to the push plate assembly 40, and the meshing tooth plate 32 is directly connected to the push plate assembly 40. When the meshing tooth plate 32 is subjected to driving force, the push plate assembly 40 also moves up and down, realizing the synchronous movement of the two. Thus, the subsequent push plate assembly 40 can drive the anti-latch tongue 50 to move and thereby retract the anti-latch tongue 50 into the housing 10. Through such a setting, the driving motor 20 can transmit power to the push plate assembly 40 through the meshing gear 31 and the meshing tooth plate 32, realizing the up-and-down movement of the push plate assembly 40. Through the control of the driving motor 20, the movement position and speed of the push plate assembly 40 can be adjusted, thereby realizing the function of the automatic lock body.

[0055] In some embodiments, the push plate assembly 40 further comprises a moving plate 42, which is connected to the meshing tooth plate 32; the elbow arm 41 comprises an end portion 412 and a connecting portion 411, and the end portion 412 is located at both ends of the connecting portion 411, and the elbow arm 41 is rotationally connected to the connecting plate through the connecting portion 411, wherein one end portion 412 is connected to the anti-latch tongue 50.

[0056] The elbow arm 41 comprises an end portion 412 and a connecting portion 411, and the end portion 412 is located at both ends of the connecting portion 411. The elbow arm 41 is rotationally connected to the connecting plate through the connecting portion 411, wherein one end portion 412 is connected to the anti-latch tongue 50. In this embodiment, the elbow arm 41 is rotationally connected to the connecting plate through the connecting portion 411, and the connecting plate is connected to the moving plate 42. When driving force is transmitted to the moving plate 42, the moving plate 42 causes the connecting plate to move accordingly. At this time, the end of the connecting portion 411 connected to the elbow arm 41 is also affected by the moving plate 42, causing the elbow arm 41 to rotate.

[0057] When the elbow arm 41 rotates, the end portion 412 of the elbow arm 41 abutting against the anti-latch tongue 50 can drive the anti-latch tongue 50 to move upward, and at this time the anti-latch tongue 50 can be retracted into the housing 10.

[0058] In some embodiments, the housing 10 is provided with a limiting groove 11, and the limiting groove 11 is arranged in an arc shape; the end portion 412 of the elbow arm 41 is accommodated in the limiting groove 11; and the elbow arm 41 can move along the limiting groove 11.

[0059] The arc shape of the limiting groove 11 plays a limiting and guiding role in the movement of the toggle arm 41. The end 412 of the toggle arm 41 closely matches the limiting groove 11, so that the toggle arm 41 can only move along the arc path of the limiting groove 11. Through such a setting, it can be ensured that the toggle arm 41 is limited during movement and can only move within a predetermined range. The toggle arm 41 that abuts against the anti-latching tongue 50 can be prevented from being offset in position when subjected to an opposite force from the anti-latching tongue 50.

[0060] In some embodiments, a strip-shaped hole 421 is vertically formed on the moving plate 42, and a limiting post 12 is arranged on the shell 10, and the limiting post 12 is arranged in the strip-shaped hole 421.

[0061] When the moving plate 42 moves, the strip-shaped hole 421 and the limiting post 12 can guide the moving plate 42 to move vertically and prevent it from being offset. The limiting post 12 passes through the strip-shaped hole 421 to limit the movement range of the moving plate 42, so that the movement range of the moving plate 42 is the length of the strip-shaped hole 421, and the stability in the vertical direction is ensured. In this way, it can be ensured that the moving plate 42 will not be offset during movement.

[0062] In some embodiments, the moving plate 42 includes an abutting portion 422 corresponding to the position of the micro switch 70, and the moving plate 42 can drive the abutting portion 422 to move so that the abutting portion 422 contacts the micro switch 70.

[0063] The abutting portion 422 on the moving plate 42 corresponds to the position of the micro switch 70. The moving plate 42 can drive the abutting portion 422 to move so that the abutting portion 422 contacts the micro switch 70. Through such a setting, the interaction between the moving plate 42 and the micro switch 70 can be realized. When the moving plate 42 moves to a specific position, the abutting portion 422 contacts the micro switch 70, so that the micro switch 70 controls the driving motor 20 to stop rotating, at this time, the transmission assembly 30 and the push plate assembly 40 no longer move, and the anti-latching tongue 50 can be retracted and fixed in the shell 10.

[0064] In some embodiments, a reset assembly 80 is further included, which is arranged in the shell 10. The reset assembly 80 includes a reset plate 81 and a first reset spring 82. One end of the reset plate 81 is connected with the anti-latching tongue 50, and the other end is connected with the first reset spring 82. The reset plate 81 can drive the anti-latching tongue 50 to move up and down when moving, and the first reset spring 82 can be stretched when the reset plate 81 moves.

[0065] The reset assembly 80 comprises a reset plate 81 and a first reset spring 82. One end of the reset plate 81 is connected with the anti-latch 50, and the other end is connected with the first reset spring 82. When the reset plate 81 moves left and right, the anti-latch 50 moves up and down correspondingly. When the reset plate 81 moves, the first reset spring 82 is compressed. Through such a setting, the opening and closing of the anti-latch 50 can be realized. When the reset plate 81 moves, the first reset spring 82 is stretched, and the reset spring 82 has elastic force. Then, when the handle is twisted, the handle shaft and the handle tab drive the connecting rod to move, pull back the anti-latch 50 and the movement limiting assembly, and then the door can be directly opened. The crank arm 41 returns to the original position under the action of the tension force after the door is opened.

[0066] In some embodiments, the reset plate 81 is provided with a moving opening 811, and the anti-latch 50 comprises a connecting column 51 arranged in the moving opening 811 and abutting against the inner inclined wall of the moving opening 811. The connecting column 51 on the anti-latch 50 moves up and down synchronously with the anti-latch 50.

[0067] In some embodiments, the first reset spring 82 comprises a first connecting ring 821 and a second connecting ring 822, and the housing 10 is further provided with a mounting column 13. The first connecting ring 821 is sleeved on the mounting column 13, and the second connecting ring 822 is connected with the reset plate 81.

[0068] The first connecting ring 821 is sleeved on the mounting column 13 to fix the first reset spring 82. The second connecting ring 822 is connected with the reset plate 81 to link the reset plate 81 and the first reset spring 82 together. Through such a setting, the force transmission of the first reset spring 82 to the reset plate 81 can be realized. The first connecting ring 821 fixes the position of the first reset spring 82 by being sleeved on the mounting column 13, and the second connecting ring 822 is connected with the reset plate 81, so that the reset plate 81 can move through the compression or release of the first reset spring 82. Thus, the reset function of the reset plate 81 can be realized. When resetting is needed, the first reset spring 82 can be compressed or released through appropriate operation, so as to restore the reset plate 81 to the initial position.

[0069] In some embodiments, the top of the latch 60 is provided with a second reset spring 61 abutting against the latch 60.

[0070] By arranging the second reset spring 61 in the latch 60, when the door is opened, the vertical surface of the latch 60 abuts against the door frame, the user rotates the latch 60 by 45 degrees by applying force, the vertical surface becomes an inclined surface abutting against the door frame, and then the latch 60 retracts along the inclined surface. At this time, the second reset spring 61 is compressed. After the door is opened, the latch 60 returns to the initial position under the action of the force of the compressed second reset spring 61.
