[0018] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] The utility model provides the following technical solutions:
[0021] As attached Figure 1-3 As shown, the utility model 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, and 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 presses against the lock tongue 2 and drives the lock tongue 2 to move in the lock box 1, and 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 this design, by setting up a fully automatic clutch device 3, the automatic unlocking and automatic locking functions of the lock body can be realized without manual operation, thereby improving the convenience of using the lock body, and the setting 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 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 rapid locking of the lock body.
[0022] Furthermore, a door frame 5 is provided on one side of the lock box 1, and a first magnetic part 6 is provided 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 provided 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 provided on the inner wall of the lock box 1, and one end of the second magnetic part 8 is 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 this 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 amount of space for movement. 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 rotation 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, thereby causing the lock tongue limiting end 12 to disengage the clamping groove 11, allowing the lock tongue 2 to enter the door frame 5 and lock. This design uses two magnets with the same polarity that repel each other to achieve the quick locking function of the lock body, without the need for additional accessories, simplifying the lock body structure, and reducing the extension cost and assembly difficulty.
[0023] 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.
[0024] Furthermore, the limiting member 7 has a magnetic transmission end 9 and a lock tongue clamping end 10, and a clamping groove 11 is provided on the lock tongue clamping end 10. 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 limiting member 7. Specifically, in this 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 it possible. When the lock tongue 2 is inserted into the clamping groove 11, it can slide smoothly along the inclined surface 31, thereby achieving 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 limiting member 7, ensuring the fixing effect of the lock tongue 2 during use.
[0025] Furthermore, an elastic member 13 is provided on one side of the lock tongue engaging end 10. During the rotation of the limiting member 7, the lock tongue engaging end 12 compresses the elastic member 13. Specifically, in this embodiment, the elastic member 13 is a torsion spring, the two ends of which are respectively engaged with the lower portion of the lock tongue engaging 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 lock tongue engaging end 10 of the limiting member 7 gradually compresses the torsion spring, causing the torsion spring to accumulate elastic potential energy. When the door is opened, the lock 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, thereby causing the limiting member 7 to return to its original position and engage and limit the lock tongue 2 again.
[0026] Furthermore, the fully automatic clutch device 3 includes a bolt transmission member 14 and a bolt power assembly 15. The two ends of the bolt transmission member 14 are respectively connected to the bolt power assembly 15 and the bolt 2. The bolt transmission member 14 is rotatably arranged in the lock box 1. The bolt power assembly 15 drives the bolt transmission member 14 to rotate, and during the rotation of the bolt transmission member 14, the bolt 2 is driven to move within the lock box 1. Specifically, in this embodiment, the bolt transmission member 14 rotates under the drive of the bolt power assembly 15, and during the rotation process, the bolt 2 is pushed to move within the lock box 1, thereby achieving locking and unlocking actions. This structural arrangement has high reliability and stability. To ensure smooth rotation of the bolt transmission member 14, its surface is finely processed to reduce friction and extend its service life. The bolt power assembly 15 is typically driven by a motor and connected to the bolt transmission member 14 via gears, belts, or other transmission mechanisms to ensure precise control of the position of the bolt 2.
[0027] Furthermore, the lock tongue power assembly 15 includes a motor 16 and a motor transmission member 17, the motor 16 has an output shaft, the motor transmission member 17 is sleeved on the output shaft, the motor transmission member 17 is provided with an external helical tooth 18, the lock tongue transmission member 14 has a main body 19, a gear connecting part 20 and a lock tongue connecting part 21, a second rotating hole 33 is opened on the main body 19, a second rotating end 32 is protruded on the inner wall of the lock box 1, the second rotating end 32 extends into the second rotating hole 33 and is rotatably connected to the lock tongue transmission member 14, the main body 19 is rotatably connected to the inner wall of the lock box 1, the gear connecting part 20 is meshed with the external helical tooth 18 on the motor transmission member 17, and the lock tongue connecting part 21 is formed by the side of the main body 19 away from the gear connecting part 20 protruding toward the lock tongue 2. Specifically, in this embodiment, the motor 16 is a forward and reverse motor as known in the art. A motor transmission member 17 having external helical teeth 18 is sleeved on the output shaft of the motor 16, thereby driving the motor transmission member 17 to rotate during operation. During the rotation of the motor transmission member 17, the gear connection 20 on the bolt transmission member 14, which is engaged with the external helical teeth 18, drives the bolt transmission member 14 to rotate about the second rotating end 32. During the rotation of the bolt transmission member 14, the bolt connection 21 pushes the bolt 2 to move. Through this simple structural design, precise control and stable drive of the bolt are achieved. In actual application, the forward and reverse rotation of the motor 16 enables the bolt transmission member 14 to achieve bidirectional motion, thereby enabling the opening and closing operation of the bolt 2.
[0028] Furthermore, the lock tongue 2 includes a lock tongue body 22 and a lock tongue transmission portion 23. The lock tongue transmission portion 23 is provided with a first transmission groove 24 and a second transmission groove 25. The lock tongue connection portion 21 of the lock tongue transmission member 14 extends into the first transmission groove 24 and is connected to the lock tongue 2. A manual unlocking member 26 is provided in the lock box 1. The manual unlocking member 26 is rotatably provided in the lock box 1. One end of the manual unlocking member 26 extends into the second transmission groove 25 and is connected to the lock tongue 2. Specifically, in this embodiment, by providing the manual unlocking member 26, it is possible to prevent the fully automatic clutch device 3 from being unable to unlock in the event of a malfunction or power outage, thereby ensuring the safety and reliability of the lock system. Manual unlocking member 26 includes a manual transmission portion 34 that projects toward second transmission slot 25. This portion extends into second transmission slot 25 and connects to lock tongue 2. By rotating manual unlocking member 26, the connection between manual transmission portion 34 and lock tongue 2 allows manual transmission portion 34 to push lock tongue 2 during rotation, thereby achieving manual unlocking. During normal operation, manual unlocking member 26 remains stationary, and lock tongue 2 cooperates with fully automatic clutch mechanism 3 via lock tongue transmission member 14 to ensure automatic opening and closing of the lock body.
[0029] Furthermore, a main control module 27 and a charging module 28 are further provided in the lock box 1, and both the main control module 27 and the charging module 28 are connected to the motor 16. Specifically, in this embodiment, the main control module 27 is a main control circuit board, and the charging module 28 is a charging circuit board and a charging interface provided on the charging circuit board. A guide groove 35 is provided on the main control module 27, and a guide end 35 is protruded from the lock tongue transmission portion 23 of the lock tongue 2. The guide end extends into the guide groove 35 to guide and limit the movement of the lock tongue 2, thereby preventing the movement of the lock tongue 2 from deviation.
