BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the combined structure of the present invention; Figure 2 It is a schematic diagram of the internal planar structure of the present invention; Figure 3 It is a schematic diagram of the exploded bottom view structure of the present invention; Figure 4 It is a schematic diagram of the exploded top view of the structure of the present invention. DETAILED DESCRIPTION

[0016] like Figure 1-Figure 4 The figure shows a magnetic lock unlocking structure comprising a housing 1, a lock tongue 2, and a tongue box 3. The housing 1 has an opening through which the lock tongue 2 extends and retracts. When the lock tongue 2 extends from the opening, it inserts into the tongue box 3. The lock tongue 2 moves in and out of the housing 1 and, when extended, into the tongue box 3. This is the basic design layout. It should be noted that the tongue box 3 is mounted on the door frame, and the door is opened and closed through the cooperation between the lock tongue 2 and the tongue box 3.

[0017] When the lock tongue 2 is in the locked state, the motor unlocking mechanism or the manual unlocking mechanism drives the movable member 4 to move so that the lock tongue 2 is switched to the unlocked state. When the motor unlocking mechanism drives the lock tongue 2 to switch from the locked state to the unlocked state, the manual unlocking mechanism is used to drive the movable member 4 to move, and the movable member 4 is separated from the movable member 4; when the manual unlocking mechanism drives the lock tongue 2 to switch from the locked state to the unlocked state, the motor unlocking mechanism is used to drive the movable member 4 to move, and the movable member 4 is separated from the movable member 4. In this embodiment, the electronic unlocking mechanism and the manual unlocking mechanism are two independent mechanisms. When any one of the unlocking mechanisms drives the lock tongue 2 to switch from the locked state to the unlocked state, the other unlocking structure is not affected. That is to say, the two unlocking mechanisms are independent of each other. The lock tongue 2 is locked by magnetic attraction in the locked state, and the unlocking can be driven by the motor unlocking mechanism or by the manual unlocking mechanism.

[0018] The device further comprises a movable member 4, a driving member 5, and a transmission member 6. The movable member 4 is fixedly connected to the lock tongue 2. The transmission member 6 rotates circumferentially via the driving member 5, which in turn abuts against the movable member 4 to push it back and forth linearly. The lock tongue 2 and the tongue box 3 are magnetically attracted to each other. The driving member 5 provides the power source, and the transmission member 6 converts the rotational torque into linear movement of the movable member 4, which helps reduce space usage and provides efficient and reliable output. Compared to direct meshing transmission methods such as racks, this structure has a higher fault tolerance, adapts to frequent opening and closing, and significantly improves service life. In this embodiment, the motor-driven travel is limited to a certain range, and the remaining travel is achieved through magnetic attraction. This not only avoids assembly or design errors, preventing the lock tongue 2 from colliding with the tongue box 3 or the retaining structure within the housing 1, but also ensures the stability of the opening and closing state, preventing large gaps after a period of use. The housing 1 also has a charging port 24 for convenient charging, and a battery or dry cell battery is also installed inside.

[0019] The movable part 4 is provided with an abutment groove 7, and the transmission part 6 is provided with an abutment block 8. The abutment block 8 abuts against the wall of the abutment groove 7 in the abutment groove 7 to link the transmission part 6. The movable part 4 can be pushed to move only when the abutment block 8 contacts the wall of the abutment groove 7. There is no need to accurately design and verify the motor output, which is conducive to speeding up production efficiency and improving fault tolerance. The driving part 5 is a motor, and a tooth edge 9 is provided at the outer edge of the transmission part 6. A gear 10 that is meshed and linked is provided between the motor and the transmission part 6. A built-in power supply can also be designed to facilitate user use. The relative circumference of the tooth edge 9 is approximately the same as the stroke, which is conducive to controlling the rotation distance of the movable part 4. The gear 10 connection is relatively stable and reliable, and does not rely on precise calculation and design here. The abutment block 8 is a waist-shaped structure. The waist-shaped structure is a design with semicircular ends and a square middle. The enhanced smoothness of the end is conducive to abutment linkage and reduces the possibility of jamming.

[0020] The movable member 4 also includes a spring 11, with one end of the spring 11 fixedly connected to it, causing it to move away from the tongue box 3. As a supplement to the motor output, the spring 11 prevents the lock tongue 2 from being magnetically attracted and reentering the tongue box 3. It should be noted that since the motor drives the lock tongue 2 away from the tongue box 3, the use of the spring 11 can help provide a greater initial force. At the same time, it does not hinder the next use of the lock, for example, if the magnetic force is greater than the elastic restoring force of the lock tongue 2 when it approaches the tongue box 3.

[0021] The housing 1 also houses a circuit board 12, which is equipped with a first sensing position 13 and a second sensing position 14. The transmission member 6 is provided with a positioning block 15, which passes through the first and second sensing positions 13 and 14 during the rotational path of the transmission member 6. Sensing elements can be designed in the first and second sensing positions 13 and 14, which, in conjunction with the positioning block 15, achieve sensing and positioning, facilitating feedback loops within the circuit. The above is just one implementation method, not the sole limitation, and the circuit or component design represents a mature technical approach.

[0022] The manual unlocking mechanism includes a mechanical lock core 16 that abuts the linkage movable part 4 and has an elastic reset tendency. The driving part 5 and the mechanical lock core 16 each constitute an independent mechanical state and electronic state. A spring 2 17 is provided in the housing 1 to drive the mechanical lock core 16 to elastic reset. The reset is driven by the spring 2 17, which avoids the mechanical opening method from affecting the electric drive structure, thereby improving the safety and reliability of use. In this embodiment, one end of the spring 2 17 is fixed to the lock core, and the other end abuts the fixed plate 1 21. The housing 1 is provided with a mounting post for the central sleeve of the spring 2 17, which will not be elaborated or limited in detail here. Similarly, the spring 11 is also provided with a mounting post, and the two ends of the spring 11 also abut the fixed plate 1 21 and the movable part 4 respectively. As for the various linkage forms of the mechanical lock core 16 abutting the movable part 4, they will not be elaborated or limited in detail here.

[0023] The movable part 4 is provided with a slide groove 18, and the transmission part 6 is provided with a fixed shaft 19 passing through the slide groove 18 at the center of rotation, and the fixed shaft 19 slides relative to the slide groove 18. The movable part 4 is provided with a slide groove 20, and the mechanical lock core 16 passes through the slide groove 20 and slides relative to it. The design of the slide groove 18 and the slide groove 20 makes the spatial structure more compact and can also avoid the complexity of the installation structure of each component. The movable part 4 is provided with a fixed plate 1 21 and a fixed plate 2 22 on opposite sides, and the driving part 5 is fixedly assembled on the fixed plate 1 21. The fixed plate 2 22 is fixedly connected to the circuit board 12, and the fixed plate 2 22 is provided with a groove 23 at the outer edge for the positioning block 15 to move. The fixed plate 1 21 and the fixed plate 2 22 are provided for the installation of different components, and corresponding slots are also provided in themselves for the installation of the movable part 4 or other components.

[0024] Overview of its operating principle: When the lock is locked, the motor drives the transmission member 6, which in turn drives the movable member 4 and the lock tongue 2. At the end of the movable member 4's travel, the lock tongue 2 is fully magnetically engaged and secured in the lock box 3. A high magnetic force can be configured to lock solely by magnetic attraction. Conversely, the motor's action disengages the lock tongue 2 from the lock box 3, accelerating the opening of the spring 11 and effectively preventing the lock tongue 2 from becoming lodged in the lock box 3. Finally, the lock can also be opened with a mechanical key, with a flexible reset feature designed to minimize the conflict between purely mechanical opening and closing and motor-operated operation.
