Description

Technical Field

[0001] The invention relates to the technical field of electronic locks, and in particular to the improvement of an electromagnet driving mechanism for an electronic padlock. Background Art

[0002] Traditional electronic locks generally have only one set of locking mechanisms, which only lock the locking slots on the side walls of the long arm end or the short arm end of the lock beam. Due to the uneven force, the lock beam is prone to deviate to one side in the lock beam slot on the lock body under the elastic force of the lock pin spring, which is prone to jamming, especially when the gap between the lock beam and the lock beam slot on the lock body is small, resulting in failure of the electromagnet to unlock. Increasing the gap between the lock beam and the lock beam slot on the lock body will reduce the safety and reliability of the product. Thin objects can be inserted into the gap between the two, pushing the lock pin back and unlocking.

[0003] In addition, traditional electronic padlocks generally use an electromagnet in the lock body to control the movement of the lock pin. For a general electromagnet, its working process is that after power is applied, the iron core changes from the original extended or retracted state to retracted or extended. The power consumption required for the electromagnet to operate is relatively large. The lock body space of the electronic padlock is limited, and the battery capacity installed therein is extremely limited. The operation of the electromagnet will consume power quickly, affecting the battery life of the electronic padlock, making the electronic padlock inconvenient to use. Summary of the invention

[0007] The technical solutions for further limiting the present invention include:

[0008] The lock body is provided with a lock pin guide groove for accommodating a lock pin and a lock pin spring; a positioning pin is vertically provided on the lock pin, and a positioning groove is provided on the lock pin guide groove for allowing the positioning pin to extend and for positioning the extension stroke of the lock pin; the electromagnet is contracted by the tossing of the electromagnet paddle, and the electromagnet iron core shaft in the energized state cooperates with the positioning pin to block the lock pin from extending under the elastic force of the lock pin spring.

[0022] The structure of the present invention is further described below in conjunction with the accompanying drawings and preferred specific embodiments of the present invention.

[0023] Reference Figures 1 to 5 As shown in the figure, a balanced anti-insertion double-sided locking intelligent electronic padlock disclosed by the present invention includes a lock beam 1, a lock body 2, a lock pin 3, a lock pin spring 4, a lock beam ejection spring 5, an electromagnet 6, an electromagnet control circuit and an identity verification module; the two ends of the lock beam 1 are respectively inserted into the lock body 2; the lock pin 3 is placed in the lock body 2, one end of the lock pin 3 is elastically abutted with the locking card slot 11 on the side wall of the lock beam 1, and the other end is elastically docked with the lock pin spring 4; the lock beam ejection spring 5 is placed in the lock body 2 and elastically docked with the long arm end of the lock beam 1; the iron core shaft of the electromagnet 6 is connected with the lock pin 3; the identity verification module is connected with the electromagnet control circuit, and the electromagnet control circuit is connected to control the telescopic action of the electromagnet 6; the difference between the present invention and the traditional padlock is that it also includes a lock beam pressing detection switch 7 and an electromagnet paddle 8.

[0024] Specifically, the upper side wall of the locking slot 11 of the lock pin 3 is a beveled surface. In the present invention, when the lock beam 1 is pressed in the locked state, the lock pin 3 will compress the lock pin spring 4 and retreat under the action of the beveled surface of the locking slot 11, and the lock pin 3 will be separated from the locking slot 11 and elastically pressed against the side wall of the lock beam 1, achieving Figure 2 Status shown.

[0025] The lock beam pressing detection switch 7 is arranged at a lower position corresponding to the end of the lock beam 1 in the lock body 2, and is used to detect that the lock beam 1 continues to press down after being in the locked position, and provide a start signal for the electromagnet control circuit to control the electromagnet to be energized; that is, after the lock pin 3 disengages from the locking slot 11 and elastically presses against the side wall of the lock beam 1, the lock beam pressing detection switch 7 is triggered.

[0026] The electromagnet pick 8 is arranged in the lock body 2, and the electromagnet pick 8 is rotatably connected to the inner wall of the lock body 2 through the rotating shaft 81. The rotating shaft 81 makes the electromagnet pick 8 form a lever structure. One end of the electromagnet pick 8 cooperates with the lock beam 1 to push, and the other end is correspondingly connected to the bottom end of the iron core shaft of the electromagnet 6. When the lock beam 1 is in the locked position and continues to press down, the electromagnet pick 8 pushes the iron core shaft 61 of the electromagnet 6 to contract, and the top end of the iron core shaft 61 of the electromagnet 6 extends to the front of the blocking lock pin 3 extending to the upper locking position; that is, the electromagnet pick 8 is equivalent to a lever. In the locked state of the present invention, the lock beam 1 is pressed, one end of the electromagnet pick 8 is pressed down, and the other end pushes the bottom end of the iron core shaft of the electromagnet 6 to move upward, compressing the spring sleeved on the iron core shaft 61 of the electromagnet 6. Compared with the traditional electronic padlock that drives the bottom end of the iron core shaft of the electromagnet 6 to move upward through electromagnetic force, the present invention can effectively reduce power consumption. After the iron core shaft 61 of the electromagnet 6 of the present invention is contracted, the top end of the iron core shaft 61 extends to the front of the blocking lock pin 3 extending to the upper locking position. If the electromagnet 6 is energized at this time, the lock beam 1 is released. Although the iron core shaft 61 of the electromagnet 6 loses the upward thrust of the electromagnet paddle 8, the iron core shaft 61 of the electromagnet 6 remains stationary. The top end of the iron core shaft 61 limits the lock pin 3 to reset under the action of the lock pin spring 4, and the lock pin 3 cannot enter the locking slot 11. Under the action of the lock beam ejection spring 5, one end of the lock beam 1 is separated from the lock body 2 to achieve unlocking, achieving the following effect. Figure 4 After the core shaft 61 of the electromagnet 6 contracts, if the electromagnet 6 is not powered at this time, the lock beam 1 is released, the core shaft 61 of the electromagnet 6 is reset synchronously, and the lock pin 3 enters the locking slot 11, and the present invention still maintains the locked state.

[0027] The electromagnet control circuit controls the electromagnet 6 to be energized to maintain the state within a preset time after the identity authentication module is verified and the lock beam press detection switch 7 is pressed and turned on. That is, when the identity authentication module has not verified the identity of the operator, only the lock beam press detection switch 7 is pressed and turned on, and the electromagnet control circuit will not control the electromagnet 6 to be energized.

[0028] Locking operation: When the present invention is in the open state, a person manually presses the lock beam 1 to retract the lock beam 1 into the lock body 2. The lock beam 1 pushes the lock pin 3 backward under the action of the end inclined surface. Then, under the action of the lock pin spring 4, the lock pin 3 locks the lock beam 1, which is basically the same as the locking principle of a traditional padlock.

[0029] The specific matching structure of the lock pin 3 and the iron core shaft 61 of the electromagnet 6 can be: a lock pin guide groove 21 for accommodating the lock pin 3 and the lock pin spring 4 is provided in the lock body 2; a positioning pin 31 is vertically provided on the lock pin 3, and a positioning groove is provided on the lock pin guide groove 21 for the positioning pin 31 to extend and position the extension stroke of the lock pin 3; the electromagnet 6 iron core shaft in the energized state cooperates with the positioning pin 31 to block the lock pin 3 from extending under the elastic force of the lock pin spring 4. Figure 4 As shown, the positioning pin 31 not only cooperates with the positioning groove to limit the leftward movement distance, but also cooperates with the iron core shaft 61 of the electromagnet 6 to block.

[0030] In order to solve the technical deficiencies of the existing electronic padlocks, such as the uneven force and poor safety and reliability caused by the single-group locking mechanism, and to improve the reliability of the present invention, the locking slot 11 is arranged on the inner side of the short arm end of the lock beam 1; the inner side of the long arm end of the lock beam 1 also has a second locking slot 12 with the same structure as the locking slot 11; an anti-insertion lock pin guide slot 22 is arranged in the lock body 2, and an anti-insertion lock pin 9 for locking with the second locking slot 12 is arranged in the anti-insertion lock pin guide slot 22, and an anti-insertion lock pin spring 91 for applying elastic force to the anti-insertion lock pin 9 in the direction of the second locking slot 12 is also arranged in the anti-insertion lock pin guide slot 22; the anti-insertion lock pin spring 91 for applying elastic force to the anti-insertion lock pin 9 in the direction of the second locking slot 12 is arranged; the anti The latch pin 9 is provided with an iron core avoidance groove corresponding to the electromagnet 6, and the iron core shaft passes through the iron core avoidance groove to the bottom of the anti-insert lock pin 9. A locking card block 62 is provided at the position of the iron core shaft below the anti-insert lock pin 9, and a locking card block positioning groove is provided on the lower surface of the anti-insert lock pin 9. When the anti-insert lock pin 9 is pushed down by the lock beam (1) and retracted, the locking card block 62 is placed in the locking card block positioning groove, and the anti-insert lock pin 9, that is, the iron core shaft 61 of the electromagnet 6, cooperates with the lock pin 3 at the upper end and cooperates with the anti-insert lock pin 9 at the lower end, realizing a double insurance structure, and the two ends of the lock beam 1 inserted into the lock body 2 are locked at the same time, with balanced force and good safety and reliability.

[0031] The specific structure of the lock beam 1 and the electromagnet pick 8 can be: an anti-dropout pin 13 is provided on the side wall of the long arm end of the lock beam 1, and the anti-dropout pin 13 is located above the electromagnet pick 8 and pushes with the electromagnet pick 8.

[0032] The specific structure of the lock body 2 may include a front shell and a rear shell, which are riveted and buckled together to form a cavity, a baffle 10 is provided on the top surface of the cavity, and two through holes corresponding to the lock beam 1 are provided on the baffle 10.

[0033] The identity verification module can be an existing fingerprint verification module or a password verification module. According to needs, a Bluetooth communication module can also be connected to the identity verification module to perform identity verification operations before intelligent unlocking through a smart phone via Bluetooth communication.
