[0058] In order to facilitate a concise understanding of the other features and advantages of the present invention and the effects achieved thereby, the present invention is now described in detail with reference to the accompanying drawings as follows:

[0059] See also Figure 1 As shown, the Figure 1 This is a schematic diagram of the appearance of the utility model.

[0060] Please refer to Figure 2、 Figure 3 As shown, an electric lock, comprising:

[0061] A housing 1 is provided with a locking tongue 11 therein.

[0062] A driving device 2 is arranged in the housing 1. The driving device 2 is provided with a motor 21, a screw 22 and a moving part 23. The motor 21 is connected to the screw 22. The motor 21 can rotate the screw 22. The moving part 23 is connected to the screw 22. The rotation of the screw 22 can move the moving part 23 back and forth. The moving part 23 is provided with a protrusion 231.

[0063] A linkage device 3 is provided in the housing 1. The linkage device 3 is provided with a linkage member 31 and a push member 32. The linkage member 31 is provided with a limiting groove 311. The protrusion 231 is provided in the limiting groove 311. The push member 32 is provided with a first end 321, a second end 322 and a third end 323. The first end 321 is connected to the linkage member 31. The third end 323 is against the lock tongue 11. In addition, the push member 32 is provided with a first elastic member 324. Figure 4 shown.

[0064] At least one manual device 4 is disposed in the housing 1 and includes a driving member 41 and a driven member 42 . The driven member 42 is disposed beside the driving member 41 . One end of the driving member 41 abuts against the second end 322 of the pushing member 32 .

[0065] A controller 5 is disposed in the housing 1 and connected to the driving device 2 . The controller 5 can control the operation of the motor 21 .

[0066] The housing 1 may be provided with a sensing device 12 , which is provided on a side of the housing 1 close to the door frame and connected to the controller 5 . The sensing device 12 is a magnetic spring.

[0067] The first elastic member 324 is a return spring.

[0068] The housing 1 may be provided with a second elastic member 13 , the locking tongue 11 is connected to the second elastic member 13 , and the second elastic member 13 is a spring.

[0069] The follower 42 is provided with a pressing portion 421 .

[0070] The housing 1 is provided with a first micro switch 14 . The first micro switch 14 is connected to the controller 5 . The first micro switch 14 is squeezed by the squeezing portion 421 .

[0071] The present invention can be connected to mains electricity or an external power supply to provide operation for the controller 5 and the driving device 2 . Since this belongs to the prior art and is not the main feature technology of the present invention, it will not be described in detail here.

[0072] Please refer to Figure 5 As shown, a plurality of second micro switches 15 may be provided in the housing 1 of the present invention, and the second micro switches 15 are connected to the controller 5. When the second micro switches 15 are squeezed, the controller 5 stops the motor 21. Since this belongs to the prior art and is not the main characteristic technology of the present invention, it will not be described in detail here.

[0073] Please refer to Figure 6 、 Figure 8 When the controller 5 receives a valid signal, such as a fingerprint, password, etc., or the user uses the driving member 41 of the manual device 4 to push the driven member 42, and the first micro switch 14 is not squeezed by the squeezing portion 421, the controller 5 will transmit electricity to the driving device 2, so that the motor 21 of the driving device 2 operates, and the motor 21 drives the screw 22 to rotate, thereby causing the screw 22 to drive the moving member 23 to move toward the motor 21, so that the protrusion 231 drives the linking member 31 to move toward the motor 21, thereby driving the first end 321 of the pushing member 32 to rotate toward the motor 21, so that the third end 323 of the pushing member 32 pushes the lock tongue 11 to retract into the housing 1, thereby achieving the effect of opening the door, and the protrusion 231 is located at one end of the limiting groove 311, so that the linking member 31 and the pushing member 32 are affected by the protrusion 231 and do not move; please refer to Figure 7 As shown, when the door is closed, the sensing device 12 will sense the magnetic field on the door panel 6, causing the controller 5 to drive the motor 21 to operate in the opposite direction, causing the screw 22 to rotate in the other direction and drive the moving member 23 to move in the opposite direction, so that the protrusion 231 moves in the limiting groove 311, and the connecting member 31 and the pushing member 32 are not affected by the above-mentioned protrusion 231, thereby allowing the first elastic member 324 of the pushing member 32 to restore the pushing member 32 to its original position, thereby driving the third end 323 of the pushing member 32 to push the lock tongue 11 outward from the housing 1, or the utility model is provided with a second elastic member 13, when the lock tongue 11 is pushed by the third end 323 of the pushing member 32 and retracted into the housing 1 and fixed, the second elastic member 13 is also compressed, and when the pushing member 32 no longer pushes the lock tongue 11, the second elastic member 13 will release the elastic force to push the lock tongue 11 outward.

[0074] Please refer to Figure 9As shown, when the controller 5 and the drive device 2 cannot operate due to a power outage or a failure of the motor 21, an external force can be used to push the driving member 41 of the manual device 4 to push the driven member 42, thereby causing the driven member 42 to squeeze the second end 322 of the pushing member 32, so that the third end 323 of the pushing member 32 pushes the lock tongue 11, causing the lock tongue 11 to retract into the housing 1, thereby achieving the effect of manually opening the door. When the external force is no longer applied, the first elastic member 324 will restore the pushing member 32 to its original position, thereby driving the third end 323 of the pushing member 32 to push the lock tongue 11 outward from the housing 1, and restore the door to the state shown in FIG. Figure 3 In this state, if the present invention is provided with a second elastic member 13, the second elastic member 13 will also release the elastic force to push the lock tongue 11 outward.

[0075] In this embodiment, the driving member 41 is taken as a lock core. In practice, the driving member 41 can be a lock core or a handle or a combination of the two. Figure 3 shown.

[0076] By providing the limiting groove 311 on the linkage 31 of the utility model, when the second end 322 of the pushing member 32 is pushed by the driven member 42, the limiting groove 311 on the linkage 31 can make the linkage 31 move along without being affected by the convex portion 231, thereby achieving the goal of electric door opening and manual door opening being independent of each other, so that if the power outage or the driving device 2 fails and the door cannot be opened electrically, it can be immediately switched to manual door opening, so that the effect of automatic locking or unlocking can be achieved by the driving device 2 in normal times, and the effect of manual unlocking can be achieved by the manual device 4 when there is no power or a failure.

[0077] The above-mentioned contents are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, any equivalent shapes, structures, or combinations made without departing from the spirit and scope of the present invention shall be included in the scope of protection of the present invention.
