When the driven gear 41 rotates around the insertion hole 411 as an axis At this time, the pushing member 42 rotates accordingly, thereby moving within the guide groove 44. When the pushing member 42 touches any side of the guide groove 44, the connector 43 is driven to rotate.

Of course, it is conceivable that the guide groove 44 may also be provided on the driven gear 41. At this time, the pushing member 42 is fixed on the connector 43, and the two are connected in cooperation with each other. The present invention does not limit the specific positions of the guide groove 44 and the pushing member 42. Any structure that is connected in the manner described in the present invention should fall within the protection scope of the claims of the present invention, and will not be repeated here. In this embodiment, preferably, the guide groove 44 is provided on the disc 431, and the pushing member 42 is fixed on the driven gear 41.

The smart lock includes a motor 6. The motor 6 includes a driving gear 61. The driving gear 61 is fixedly connected to the motor 6 through a screw and is meshed with the driven gear 41. The motor 6 controls the driving gear 61 to rotate, thereby driving the driven gear 41 to rotate.

The smart lock includes a motor controller 5. The motor controller 5 includes a bottom plate 51. A sensing member 52 is disposed on the bottom plate 51. The pushing member 42 includes a contact portion 421. The sensing member 52 is directly below the pushing member 42 and is movably connected to the contact portion 421. The sensing element 52 senses the position of the contact portion 421 and transmits a signal to the motor. Specifically, in the initial state, the contact portion 421 is inside the sensing element 52. When the driven gear 41 rotates, the contact portion 421 is driven away from the sensing element 52. After a certain period of time, the induction member 52 transmits a reverse signal to the motor 6 through the base plate 51, and the motor 6 drives the driving gear 61 to cause the driven gear 41 to drive the contact portion 421 to the initial position.

It should be noted that, in the present invention, the shape of the contact portion 421 is not limited, and the shape of the pushing member 42 is also not limited. However, the contact portion between the pushing member and the guide groove should be sufficient to drive the connector, and the contact portion should be According to the shape of the sensing element, any pushing element satisfying the above two points should be within the protection scope of the claims of the present invention. In addition, the present invention does not limit the form of induction of the inductive member 52. The inductive member 52 may be photocoupler induction or physical induction. Any structure that can achieve the technical effects described in the present invention shall be protected by the claims of the present invention. Within range.

The pillar 31 of the door latch controller 3 includes a key hole 311. A manual key can be inserted into the key hole 311 and rotated to manually rotate the pillar 31, thereby driving the operating member 32 to move in the groove 21, so that the door bolt 2 is in the door. The lock buckle 11 is retractable inside and outside to realize the locking and unlocking of the bolt 2.

The working process of the smart lock of the present invention is further described below.

The motor 6 of the smart lock drives the driving gear 61 by electronic equipment such as the password input of the outdoor lock body or a security card or fingerprint recognition, so that the driven gear 41 meshing with the driving gear 61 rotates around the insertion hole 411 and is fixed on the slave The pushing member 42 of the moving gear 41 rotates in the guide groove 44 with the rotation of the driven gear 41, and then touches any side of the guide groove 44 to drive the connector 43 to rotate around the center hole 4311. The transmission member 4321 touches When the driven member 33 is movably connected to drive the driven member 33 to rotate, the door bolt controller 3 rotates on the housing 1 with the pillar 31 as an axis, thereby driving the operating member 32 to move in the groove 21 to make the door The bolt 2 is retractable inside and outside the door lock buckle 11 to realize locking and unlocking of the door bolt 2.

When the door latch controller 3 rotates on the housing 1 with the pillar 31 as an axis, the projection 3121 rotates in the rotation groove 142. When the projection 3121 touches any side of the rotation groove 142, the door latch controller 3 Stop turning.

When the motor 5 cannot work normally, a manual key can be used to control the locking and unlocking of the door bolt 2. Specifically, by inserting the manual key into the key hole 311 and manually rotating the key, the door bolt controller 3 uses the pillar 31 as an axis in the housing. 1 is rotated to drive the operating member 32 to control the expansion and contraction of the door bolt 2.

When the motor 6 is in a stopped state, at this time, when the door bolt controller 3 is rotated using a manual key, the door bolt controller 3 will drive the driven gear 41 through the connector 43 and the pusher 42, and the driven gear 41 and the driving gear 61 meshes with each other, thereby driving the driving gear 61 to generate a load, so that it is not easy to control the locking and unlocking of the bolt 2 by rotating the bolt controller 3 with a manual key.

Therefore, when the door bolt 2 is extended or contracted to the door lock buckle 11, the motor controller 5 will control the driven gear 41 to return to the initial position. Specifically, when the door bolt 2 is extended or contracted to the door lock buckle 11, At this time, the contact portion 421 of the pushing member 42 is not in the sensing member 52. After a certain period of time, the sensing member 52 transmits a reverse signal to the motor 6, and the motor 6 returns the driven gear 41 to the initial position through the driving gear 61, thereby driving The pushing member 42 rotates in the guide groove 44 and returns to the initial position, and the pushing member 42 does not touch any side of the guide groove 44, so that the connector 43 does not rotate together. When the door bolt controller 3 is rotated with a manual key, at this time, the driven gear 41 is located at the initial position, the door bolt controller 3 will drive the connector 43 to rotate, and the guide groove 44 provided on the connector 43 will rotate accordingly, and The pusher 42 is always stationary in the guide groove 44 and does not touch any side of the guide groove 44, so that the driven gear 41 is not driven to rotate, and no load is generated, so that the door bolt is controlled by a manual key The expansion and contraction of 2 becomes easier.

The specific embodiments of the present invention are described in detail above.
