DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] A multifunctional motor driven electric lock, Figure 1-6, including a lock body 6 and a latch plate 2 arranged oppositely, a lock tongue assembly, a transmission assembly, a PCB main board 17 and a driving assembly electrically connected to the PCB main board 17 are provided in the lock body 6, wherein: the lock tongue assembly includes a round lock core 9 rotatably connected to the lock body 6, and a lock tongue 20 is detachably mounted on the round lock core 9 through a locking piece 21. The lock tongue assembly also includes a lock core pin 15, the round lock core 9 is sleeved on the outer side of the lock core pin 15, and the lock core pin 15 is rotatably arranged in the lock body 6, and a mounting column 91 is formed on the round lock core 9, and the lock tongue 20 is sleeved on the mounting column 91. A threaded hole is reserved on the mounting column 91, and a through hole is provided on the lock tongue 20 with the same axis as the threaded hole. The locking piece 21 is a screw, and the lock tongue 20 is a replaceable accessory as a whole. Lock tongues of different shapes can be replaced according to different application scenarios, and the applicability is stronger. When replacing, only the locking piece 21 needs to be unscrewed from the lock tongue 20, and the lock tongue 20 can be removed for replacement, which is convenient for replacement and greatly reduces the cost.

[0027] For example, if the lock tongue 20 is cylindrical, the application scenario of the electric lock is a flat door; (refer to Figure 6 (As shown in the figure), when the lock tongue 20 is flat, the application scenario of the electric lock is a swing door (heavy duty); when the lock tongue 20 is hook-shaped, the application scenario of the electric lock is a sliding door. The swing door can withstand a thrust of 1,000 kg, and the sliding door can withstand a pulling force of 500 kg. It is safer and more stable, and can meet the needs of heavy doors and occasions requiring high security. The lock tongue 20 of the corresponding shape can also be designed according to other door bodies, which is not limited here.

[0028] Furthermore, a through L-shaped groove 92 is provided on the round lock core 9, and the transmission assembly includes a travel pull plate 8 and a brake pin 18. The brake pin 18 is installed on the travel pull plate 8, and the other end extends into the L-shaped groove 92. When the lock tongue assembly is in the locked state, the brake pin 18 is against the end of the L-shaped groove 92. A lock tongue self-locking structure is designed between the lock tongue assembly and the transmission assembly. When the whole is in the locked state, the L-shaped groove 92 on the round lock core 9 will against the brake pin 18. When the door is maliciously lifted or pried open, the lock tongue 20 will not be pressed into the lock body 6, thereby realizing anti-unhooking and anti-prying functions, making the overall safety higher and more stable, and can meet the use of heavy doors and occasions requiring high security.

[0029] Furthermore, the driving assembly is connected to the transmission assembly, and the driving assembly can drive the travel pull plate 8 to move back and forth along its length direction. A waist-shaped hole 82 is provided on the travel pull plate 8 to allow the lock core pin 15 to pass through. When the travel pull plate 8 moves back and forth, the brake pin 18 drives the lock tongue assembly to rotate upward or downward to achieve locking or unlocking operations. By designing the waist-shaped hole 82, interference with the waist-shaped hole 82 can be avoided during the left and right movement of the travel pull plate 8.

[0030] Furthermore, the driving assembly includes a driving motor 12, a driving gear 11 and a linkage gear 10 meshing with the driving gear 11. The driving gear 11 is installed at the output end of the driving motor 12. A shift block 101 is integrally provided on the linkage gear 10. The linkage gear 10 is rotated in the lock body 6 through the gear pin 19. Both ends of the travel pull plate 8 are bent to form a support plate 81. When the linkage gear 10 rotates, the shift block 101 is abutted against the support plate 81, and drives the support plate 81 and the travel pull plate 8 to move. When locking, the driving motor 12 drives the driving gear 11 and the linkage gear 10 to rotate counterclockwise, and the shift block 101 drives the support plate 81 and the travel pull plate 8 to move. During the movement of the travel pull plate 8, the round lock core 9 can be driven to rotate through the cooperation of the lock core pin 15 and the brake pin 18, thereby completing the locking operation; otherwise, it is an unlocking operation.

[0031] Furthermore, the PCB main board 17 is integrated with two Hall switches 22, and a sensor 16 is embedded in one of the round lock cylinders 9. The two Hall switches 22 are respectively located at both ends of the running track of the sensor 16. When the sensor 16 senses any one of the Hall switches 22, the driving component stops working. When the sensor 16 moves to any one of the Hall switches 22, the PCB main board 17 receives the signal and can control the driving component to stop working. The Hall switch 22 can be used to assist in locating the moving position of the lock tongue assembly.

[0032] The sensor 16 may be a circular magnet.

[0033] Furthermore, a reed switch 5 is installed on the side of the lock body 6 facing the latch plate 2, and a sensing element 1 is embedded in the latch plate 2 corresponding to the reed switch. When the reed switch 5 senses the sensing element 1, the lock tongue 20 extends. A cover plate 13 and an installation panel 4 are provided on the lock body 6. The installation panel 4 and the latch plate 2 are respectively provided with a through groove 41 and a lock hole for the lock tongue 20 to extend and extend. There are two reed switches 5, one reed switch 5 is for door signal sensing, and the other reed switch 5 is for locking sensing. When the door is unlocked and closed, the latch plate 2 and the lock body 6 are closed for sensing, and the sensing element 1 on the latch plate 2 senses the reed switch 5 and outputs a signal.

[0034] The induction element 1 may be a circular magnetic core.

[0035] Furthermore, a guide rail and a torsion spring 14 are provided in the lock body 6. The travel pull plate 8 can be guided and moved along the guide rail. One end of the torsion spring 14 is connected to the travel pull plate 8. When the travel pull plate 8 moves, the travel pull plate 8 can be locked or unlocked more smoothly without any jamming problems. In addition, the designed torsion spring 14 provides a rebound force for the reset of the travel pull plate 8, which can help limit the moving position of the travel pull plate 8.

[0036] Furthermore, an emergency mechanical key component 3 is also provided in the lock body 6. The emergency mechanical key component 3 has a lever that can drive the push plate 81 to move.
