Description

Technical Field

[0001] The utility model belongs to the technical field of smart locks, and in particular relates to a mechanical and electrical separation smart lock transmission structure. Background Art

[0002] A smart lock is a lock with multiple unlocking methods. It can control the circuit or chip operation through fingerprint recognition, face recognition, and digital password input, thereby controlling the closing of the mechanical switch to complete the unlocking and locking actions.

[0003] With the advancement of science and technology, smart locks have been widely used in many fields. The existing smart lock structure is shown in the Chinese patent document with patent application number 202221761123.3, which discloses an electronic lock for a glass door, including a plywood, an outer lock body and an inner lock body. By sleeves of the second gear and the third gear on the rotating shaft and close to each other, the space occupied by the second gear and the third gear sleeves on the rotating shaft is effectively compressed. The second transmission member is meshed with the second gear and connected to the first transmission member, and the lever is connected between the rotating shaft and the lock tongue. When the key is inserted into the lock cylinder and rotated, the first gear is rotated, so that the rotation of the first gear drives the first transmission member to move, the movement of the first transmission member drives the movement of the second transmission member, the movement of the second transmission member drives the rotation of the second gear, the rotation of the second gear drives the rotating shaft to rotate synchronously, the rotation of the rotating shaft causes the movement of the lever to drive the movement of the lock tongue to realize the opening and closing of the lock, and the third gear is meshed with the output end of the motor, so that the third gear is driven by the motor to rotate and drive the rotating shaft to rotate synchronously, and the rotation of the rotating shaft causes the movement of the lever to drive the movement of the lock tongue to realize the opening and closing of the lock.

[0004] Although the above-mentioned smart lock structure can reduce the internal space of the smart lock and reduce the overall volume of the electronics to a certain extent, the internal components of the smart lock are fixedly installed in the outer lock body or the inner lock body. When the smart lock is disassembled and repaired, the outer lock body or the inner lock body is generally removed, and the splint is still clamped on the glass door. At this time, it is easy to cause the internal transmission components of the smart lock to separate and the assembly relationship to be disordered. Utility Model Content

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] When the user unlocks or locks the door electrically, the electric switch mechanism 5 is energized to drive the bolt moving mechanism 4 to retract or extend, thereby realizing the unlocking or locking of the smart lock. During this process, under the action of the transmission clutch mechanism 7, the electric switch mechanism 5 and the key switch mechanism 6 are in a state of separated transmission, so that the key switch mechanism 6 does not operate;

[0036] When the user uses the mechanical key to unlock or lock, the key switch mechanism 6 is controlled by the mechanical key. Under the action of the transmission clutch mechanism 7, the key switch mechanism 6 and the electric switch mechanism 5 are in an engaged transmission state. Therefore, the key switch mechanism 6 drives the electric switch mechanism 5 to move through the transmission clutch mechanism 7, and the electric switch mechanism 5 drives the lock tongue moving mechanism 4 to retract or extend, thereby realizing the unlocking or locking action of the smart lock.

[0037] The smart lock of this embodiment can realize both electric and mechanical key switching modes. When the smart lock is powered on and all electronic components are working normally, it can be unlocked or locked by electric means, which is very convenient to use. When the smart lock is powered off or some electronic components malfunction, resulting in the smart lock being unable to be unlocked or locked by electric means, it can be unlocked or locked by a mechanical key, avoiding the problem that the smart lock cannot be opened due to malfunction. In addition, the lock tongue moving mechanism 4, electric switch mechanism 5, key switch mechanism 6 and transmission clutch mechanism 7 in the smart lock of this embodiment are all installed on the splint 3.

The battery is connected to the control circuit board 10, and the control circuit board 10 is respectively connected to the electric switch mechanism 5, the password input module 8 and the fingerprint recognition module 9. When the user inputs a password on the password input module 8 to unlock, the password input module 8 transmits the password signal input by the user to the control circuit board 10, and the control circuit board 10 performs password pairing. When the password pairing is correct, the smart lock performs the unlocking action; otherwise, the smart lock remains locked. Similarly, when the user places the fingerprint on the fingerprint recognition module 9 for fingerprint recognition, the fingerprint recognition module 9 transmits the recognition signal to the control circuit board 10, and the control circuit board 10 performs fingerprint pairing. When the fingerprint pairing is correct, the smart lock performs the unlocking action; otherwise, the smart lock remains locked.

[0039] As a preferred embodiment, the side of the front lock housing 1 is further provided with a power interface 11 for an external power supply, and the power interface 11 is connected to the control circuit board 10.

The user can then insert the mechanical key into the key switch mechanism 6 through the keyhole 12 to activate or deactivate the smart lock.

[0041] As a preferred embodiment, the rear lock housing 2 is provided with a rotary switch 14 for the user to manually rotate to unlock, and the rotary switch 14 is connected to the electric switch mechanism 5, so that the user can quickly open the smart lock by rotating the switch 14 on the inside of the door.

When the clutch wheel 72 engages with the clutch hole 711, the mating protrusion 721 enters the clutch hole 711 and engages.

The electric switch mechanism 5 and the key switch mechanism 6 are separated.
