DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] The present invention provides the following technical solutions: As attached Figure 1-3 As shown, the present invention discloses a fully automatic lock body with a magnetic structure, including a lock box 1 installed on a door body, a lock tongue 2, a fully automatic clutch device 3 and a magnetic limit device 4 are arranged in the lock box 1, the fully automatic clutch device 3 and the magnetic limit device 4 are respectively arranged on both sides of the lock tongue 2, one end of the fully automatic clutch device 3 abuts against the lock tongue 2 and drives the lock tongue 2 to move in the lock box 1, one end of the magnetic limit device 4 is connected with the lock tongue 2 for limiting, and the magnetic limit device 4 limits the position of the lock tongue 2 in the lock box 1. Specifically, in the present design, by providing a fully automatic clutch device 3, the automatic unlocking and locking functions of the lock body can be realized without manual operation, thereby improving the convenience of using the lock body. In addition, the provision of the magnetic limit device 4 can limit the position of the lock tongue 2 when the door body is normally open, preventing the lock tongue 2 from extending out of the lock box. When the door needs to be closed and locked, the magnetic limit device 4 can quickly release the limit on the lock tongue under the action of magnetic force, so that after the door body and the door frame are completely released, the lock tongue 2 extends out of the lock box 1 and enters the interior of the door frame, thereby realizing the rapid locking of the lock body.

[0018] Furthermore, a door frame 5 is arranged on one side of the lock box 1, and a first magnetic part 6 is arranged on the door frame 5. The magnetic limiting device 4 includes a limiting part 7 and a second magnetic part 8. The second magnetic part 8 is movably arranged in the lock box 1, and the second magnetic part 8 and the first magnetic part 6 repel each other with the same poles. The limiting part 7 is rotatably arranged on the inner wall of the lock box 1, and one end of the second magnetic part 8 abuts against the limiting part 7. Under the action of the first magnetic part 6, the second magnetic part 8 moves toward the limiting part 7 and drives the limiting part 7 to rotate. The end of the limiting part 7 away from the second magnetic part 8 is connected with the lock tongue 2 for limiting. Specifically, in the present embodiment, the first magnetic member 6 and the second magnetic member 8 are magnets with the same magnetic poles. A first rotating end 29 for connecting to the limiting member is protruded on the inner wall of the lock box 1. A first rotating hole 30 is provided on the limiting member 7. The first rotating end 29 extends into the first rotating hole 30 and is rotatably connected to the limiting member 7. When the door body needs to be closed and locked, the door body is pushed so that it gradually contacts the door frame 5 until it is closed. When the door body is completely closed, a repulsive force is generated between the first magnetic member 6 on the door frame 5 and the second magnetic member 8 in the lock box 1. Due to the repulsive force in the door frame 5, the first magnetic member 6 on the door frame 5 and the second magnetic member 8 in the lock box 1 are locked. The first magnetic member 6 is fixed inside the door frame 5 and cannot move, while the second magnetic member 8 in the lock box 1 has a certain movable space. Therefore, under the repulsive force, the second magnetic member 8 moves toward the magnetic transmission end 9 of the limit member 7, and by pushing the magnetic transmission end 9, the limit member 7 rotates around the first rotating end 29. During the rotation of the limit member 7, the lock tongue clamping end 10 of the limit member 7 gradually disconnects from the lock tongue 2, so that the lock tongue limiting end 12 is separated from the clamping groove 11, so that the lock tongue 2 enters the door frame 5 for locking. This design uses two magnets with the same polarity repelling each other to realize the rapid locking function of the lock body, without the need for additional accessories, simplifying the lock body structure, and reducing the elongation cost and assembly difficulty.

[0019] Specifically, positioning blocks 36 are respectively provided on the upper and lower sides of the second magnetic component 8, and a movable groove 37 is formed between the positioning blocks 36. The second magnetic component 8 is arranged in the movable groove 37. The setting of the movable groove 37 can guide and limit the movement of the second magnetic component 8 to prevent the second magnetic component 8 from deviating in movement.

[0020] Further, the limiter 7 has a magnetic transmission end 9 and a lock tongue clamping end 10, a clamping groove 11 is provided on the lock tongue clamping end 10, and the lock tongue 2 is provided with a lock tongue limiting end 12 corresponding to the clamping groove 11, and the lock tongue limiting end 12 extends into the clamping groove 11 and is limitedly connected with the limiter 7. Specifically, in the present embodiment, the lock tongue clamping end 10 has an inclined surface 31 adapted to the lock tongue limiting end 12, and the setting of the inclined surface 31 can make. When the lock tongue 2 is inserted into the clamping groove 11, it can slide smoothly along the inclined surface 31, so as to achieve a close fit between the lock tongue limiting end 12 and the clamping groove 11. This design not only improves the convenience of assembly, but also enhances the stability of the connection. When the lock tongue 2 is fully inserted into the clamping groove 11, the lock tongue limiting end 12 is tightly fitted with the magnetic transmission end 9 of the limiter 7, ensuring the fixing effect of the lock tongue 2 during use.

[0021] Furthermore, an elastic member 13 is provided on one side of the locking tongue clamping end 10, and during the rotation of the limiting member 7, the locking tongue limiting end 12 compresses the elastic member 13. Specifically, in the present embodiment, the elastic member 13 is a torsion spring, and the two ends of the torsion spring are respectively clamped on the lower part of the locking tongue clamping end 10 and the inner wall of the lock box 1. By providing the torsion spring, during the rotation of the limiting member 7, the locking tongue clamping end 10 of the limiting member 7 will gradually compress the torsion spring, so that the torsion spring accumulates elastic potential energy. When the door is opened, the locking tongue 2 is retracted into the lock box 1. At this time, the second magnetic member 8 is no longer subjected to the repulsive force, and no longer provides thrust to the limiting member 7, so that the limiting member 7 no longer has the force to compress the torsion spring. In this state, the elastic potential energy of the torsion spring is released to reverse the limiting member 7, so that the limiting member 7 returns to its original position, and the locking tongue 2 is clamped and limited again.

Specifically, in this embodiment, the bolt transmission member 14 rotates under the drive of the bolt power assembly 15, and pushes the bolt 2 to move in the lock box 1 during the rotation process, so as to achieve locking and unlocking actions, and such a structural setting has high reliability and stability. In order to ensure the smooth rotation of the bolt transmission member 14, its surface is finely processed to reduce friction and prolong service life. The bolt power assembly 15 is usually driven by a motor and is connected to the bolt transmission member 14 through gears, belts or other transmission mechanisms to ensure accurate control of the position of the bolt 2.

Specifically, in the present embodiment, the motor 16 is a forward and reverse motor in the prior art, and a motor transmission member 17 having external helical teeth 18 is sleeved on the output shaft of the motor 16, so that the motor transmission member 17 can be driven to rotate during the operation of the motor 16, and during the rotation of the motor transmission member 17, the gear connecting portion 20 on the lock tongue transmission member 14 meshing with the external helical teeth 18 drives the lock tongue transmission member 14 to rotate around the second rotating end 32, and during the rotation of the lock tongue transmission member 14, the lock tongue connecting portion 21 pushes the lock tongue 2 to move. Through a simple structural design, accurate control and stable driving of the lock tongue are achieved. In practical applications, the forward and reverse function of the motor 16 enables the lock tongue transmission member 14 to achieve bidirectional motion, thereby achieving the opening and closing operation of the lock tongue 2.
