[0045] Embodiment 1

[0046] refer to Figures 1 to 6 A clutch module 100 for an electronic lock comprises a housing 1, wherein the housing 1 is provided with: a lock core connector 9, the lock core connector 9 is used to connect with a mechanical lock core 210 or a switch knob 410, and the lock core connector 9 can rotate between a locking position and an unlocking position; a first meshing tooth 3, connected with the lock core connector 9; a second meshing tooth 4, connected with the lock core connector 9; a reset member 7; a clutch 5, connected with the reset member 7, and the clutch 5 is provided with a damping device 6; a driving device 2, the driving device 2 is connected with the clutch 5, and the driving device 2 includes a driving state and a non-driving state; when the driving device 2 is in the driving state, the driving device 2 drives the clutch 5 to connect with the first meshing tooth 3 or the second meshing tooth 4, and the driving device 2 drives the first meshing tooth 3 or the second meshing tooth 4 to rotate and then drives the lock core connector 9 to rotate to the locking position or the unlocking position; when the driving device 2 is in the non-driving state, the reset member 7 disengages the clutch 5 from the first meshing tooth 3 or the second meshing tooth 4.

[0047] Through the above structure, since the damping device 6 is provided in the clutch 5, the driving device 2 can drive the clutch 5 to connect with the first meshing tooth 3 or the second meshing tooth 4. Under the drive of the driving device 2, the first meshing tooth 3 or the second meshing tooth 4 drives the lock core connecting member 9 to rotate to the locking position or the unlocking position to achieve the purpose of automatic unlocking or locking. Compared with the prior art, since a reset member 7 is provided, after the purpose of unlocking or locking is achieved or when an electronic failure occurs, the driving device 2 stops driving, and the reset member 7 can make the clutch 5 quickly disengage from the first meshing tooth 3 or the second meshing tooth 4, so that the clutch 5 will not be always engaged with the first meshing tooth 3 or the second meshing tooth 4. At this time, the electronic lock can be unlocked by inserting a key into the mechanical lock core 210 or rotating the switch knob 410, which provides a guarantee for the use of the mechanical key and improves the safety and reliability of the electronic lock.

[0048] In this embodiment, the clutch 5 includes an upper cover body 51, a lower cover body 52, a clutch input tooth 53 and a clutch output tooth 54. The upper cover body 51 and the lower cover body 52 are connected to form a mounting cavity 512. The clutch input tooth 53, the clutch output tooth 54 and the damping device 6 are arranged in the mounting cavity 512. Specifically, the damping device 6 is arranged between the upper cover body 51 and the clutch output tooth 54. Through the above structure, since the damping device 6 is arranged between the upper cover body 51 and the clutch output tooth 54, a large friction force is generated between the clutch output tooth 54 and the upper cover body 51. When the driving device 2 drives the clutch input tooth 53 to rotate, the clutch output tooth 54 will generate a large reaction force relative to the clutch input tooth 53 to push the clutch 5 to swing left and right with the clutch input tooth 53 as the center, so that the driving device 2 controls the clutch 5 to connect with the first meshing tooth 3 or the second meshing tooth 4.

[0049] Furthermore, the driving device 2 includes a motor 21 and a motor output tooth 22, wherein the motor 21 is used to drive the motor output tooth 22 to rotate, and the motor output tooth 22 is meshed and connected with the clutch input tooth 53. The clutch 5 is meshed and connected with the first meshing tooth 3 or the second meshing tooth 4 through the clutch output tooth 54. Through the above structure, under the reaction force of the damping device 6, when the motor output tooth 22 rotates in the direction of the first meshing tooth 3, the clutch 5 will swing in the direction of the first meshing tooth 3 with the clutch input tooth 53 as the center until the clutch output tooth 54 meshes with the first meshing tooth 3 and stops swinging; when the motor output tooth 22 rotates in the direction of the second meshing tooth 4, the clutch 5 will swing in the direction of the second meshing tooth 4 with the clutch input tooth 53 as the center until the clutch output tooth 54 meshes with the second meshing tooth 4 and stops swinging.

[0050] Further, the locking position includes a first locking position and a second locking position. The first locking position and the second locking position are located in the first axis direction 205, and the unlocking position is located in the second axis direction 206, and the first axis direction 205 is different from the second axis direction 206. Among them, the unlocking position is located in the vertical direction, the first locking position and the second locking position are located in the horizontal direction, and the first locking position and the second locking position are symmetrically arranged with the second axis direction 206 as the symmetry axis, so that the clutch module can be used on doors with different door opening directions.

[0051] Specifically, when the door opening direction is the first direction, the lock core connector 9 is rotated to the first locking position when the door is in the locked state, and the driving device 2 drives the clutch 5 to connect with the first meshing tooth 3 and drives the first meshing tooth 3 to rotate, thereby driving the lock core connector 9 to rotate to the first locking position, and the driving device 2 drives the clutch 5 to connect with the second meshing tooth 4 and drives the second meshing tooth 4 to rotate, thereby driving the lock core connector 9 to rotate to the unlocking position; similarly, when the door opening direction is the second direction opposite to the first direction, the lock core connector 9 is rotated to the second locking position when the door is in the locked state, and the driving device 2 drives the clutch 5 to connect with the second meshing tooth 4 and drives the second meshing tooth 4 to rotate, thereby driving the lock core connector 9 to rotate to the second locking position, and the driving device 2 drives the clutch 5 to connect with the first meshing tooth 3 and drives the first meshing tooth 3 to rotate, thereby driving the lock core connector 9 to rotate to the unlocking position.

[0052] That is to say, whether the lock core connector 9 is rotated to the left or to the right, when it is turned to the locking position, the automatic locking setting of the electronic lock can be realized, which improves the adaptability of the electronic lock clutch module and greatly improves the user experience.

[0053] In this embodiment, the damping device 6 is a damping spring 61, and the damping spring 61 is pressed against between the upper cover body 51 and the clutch output tooth 54 by elastic force. Further, the damping spring 61 is a cylindrical spring, and the damping spring 61 has an upper end and a lower end. The upper cover body 51 is provided with a first limiting groove 513, and the clutch output tooth 54 is provided with a second limiting groove 514. The upper end is pressed against the first limiting groove 513, and the lower end is pressed against the second limiting groove 514. Through the above structure, the two ends of the cylindrical damping spring 61 are respectively pressed against the first limiting groove 513 of the upper cover body 51 and the second limiting groove 514 of the clutch output tooth 54, ensuring that the damping spring 61 will not be displaced or fall off during operation, thereby improving the stability and reliability of the entire damping device 6, and the design and installation structure of the damping device 6 are simple, reducing the process difficulty and improving the production efficiency.

[0054] In this embodiment, the reset member 7 is an elastic reset member 71, one end of the elastic reset member 71 is connected to the housing 1, and the other end of the elastic reset member 71 is connected to the clutch 5. When the driving device 2 stops driving, the clutch 5 disengages from the first meshing tooth 3 or the second meshing tooth 4 under the elastic reset force of the elastic reset member 71.

[0055] Specifically, the elastic reset member 71 is a reset spring clip 711, which includes a first spring arm 7111 and a second spring arm 7112. The upper cover body 51 is protruded with a first rocker handle 515, and the lower cover body 52 is protruded with a second rocker handle 516. The first spring arm 7111 and the second spring arm 7112 are clamped on the first rocker handle 515 or the second rocker handle 516 by elastic force. Through the above structure, when the motor 21 stops rotating due to various reasons, such as when the electronic lock completes the purpose of unlocking or locking, or an unpredictable fault such as a fire or power failure occurs, the motor output tooth 22 stops rotating, and the clutch input tooth 53 meshing with the motor output tooth 22 also stops rotating. In the absence of the driving force of the motor 21, the reset spring clip 711 clamped on the first crank handle 515 or the second crank handle 516 of the clutch 5 disengages the clutch 5 from the first meshing tooth 3 or the second meshing tooth 4 under the action of the reset elastic force and resets it to the initial position, ensuring that the mechanical lock core 210 used for key unlocking is not affected by the clutch 5, so that the mechanical key can perform the unlocking operation alone, thereby improving the safety and reliability of the electronic lock.

[0056] In this embodiment, the reset spring clip 711 is a "U"-shaped reset spring clip 711. The reset member 7 also includes a fixed protrusion 72 and a fixed pressure plate 73 provided on the housing 1. The reset spring clip 711 is sleeved on the fixed protrusion 72, and the fixed pressure plate 73 fixes and presses the reset spring clip 711 to the fixed protrusion 72. Through the above structure, the setting of the fixed protrusion 72 and the fixed pressure plate 73 ensures that the "U"-shaped reset spring clip 711 is firmly fixed on the housing 1, avoiding displacement or loosening of the spring clip due to vibration or external force during operation, thereby improving stability and reliability.

[0057] In this embodiment, the housing 1 is also equipped with a speed gear set 8, the first meshing teeth 3 and the second meshing teeth 4 are meshed and connected with the speed gear set 8, and the speed gear set 8 is connected to the lock core connecting member 9, so that the driving device 2 drives the first meshing teeth 3 to rotate and drives the lock core connecting member 9 to rotate to a locked position or an unlocked position through the speed gear set 8.

[0058] Furthermore, the lock core connecting member 9 includes a lock core output tooth 91 and a lock core connecting shaft 92 fixedly connected to the lock core output tooth 91, the lock core output tooth 91 is meshed and connected with the speed gear set 8, and the lock core connecting shaft 92 is used to connect with the mechanical lock core 210 or the switch knob 410. Through the above structure, when the clutch output tooth 54 is meshed and connected with the first meshing tooth 3 or the second meshing tooth 4 and rotates, the first meshing tooth 3 or the second meshing tooth 4 meshes and drives the speed gear set 8 to rotate, and then drives the lock core output tooth 91 to rotate, and finally realizes that the lock core connecting shaft 92 drives the mechanical lock core 210 or the knob switch to open or close the electronic lock.

[0059] In this embodiment, a control mainboard 10 is further included. The control mainboard 10 is electrically connected to the driving device 2 to drive the driving device 2 to be in a driving state or a non-driving state.

[0060] Furthermore, it also includes a switch detection module 20. When the switch detection module 20 detects that the lock core connector 9 is in a locked position or an unlocked position, the control main board 10 is used to control the drive device 2 to be in a non-driving state.

[0061] The switch detection module 20 includes at least two photoelectric detection devices 201 and a light blocking member 207. At least two photoelectric detection devices 201 are provided on the control main board 10, and the light blocking member 207 is provided on the lock core output tooth 91. Through the above structure, since the light blocking member 207 is provided on the lock core output tooth 91, when the lock core output tooth 91 rotates, the light blocking member 207 can be rotated with it. At this time, the light blocking member 207 plays a role of auxiliary detection. When the light blocking member 207 rotates to the photoelectric detection device 201, the photoelectric detection device 201 can receive the sensing signal and transmit the sensing signal to the control main board 10. The control main board 10 can sense whether the lock core connector 9 is in the unlocking position or the locking position, thereby controlling the motor 21 to stop driving.

[0062] In this embodiment, the switch detection module 20 includes a first photoelectric detection device 202 and a second photoelectric detection device 203. The first photoelectric detection device 202 is arranged on the control main board 10 and corresponds to the locked position. The second photoelectric detection device 203 is arranged on the control main board 10 and corresponds to the unlocked position. The light blocking member 207 is used to rotate between the first photoelectric detection device 202 and the second photoelectric detection device 203. When the light blocking member 207 rotates to the first photoelectric detection device 202, the control main board 10 controls the driving device 2 to stop driving. At this time, the electronic lock is in a locked state. When the light blocking member 207 rotates to the second photoelectric detection device 203, the control main board 10 controls the driving device 2 to stop driving. At this time, the electronic lock is in an unlocked state. Through the above structure, since the position of the first photoelectric detection device 202 is set as the first locking position of the lock core connecting member 9, when the light blocking member 207 is rotated to the first photoelectric detection device 202, the control main board 10 can recognize that the lock core connecting shaft 92 has been rotated to the first locking position through the sensing signal emitted by the first photoelectric detection device 202, and then control the motor 21 to stop driving. Similarly, when the light blocking member 207 is rotated to the second photoelectric detection device 203, the control main board 10 can recognize that the lock core connecting shaft 92 has been rotated to the unlocking position through the sensing signal emitted by the second photoelectric detection device 203, and then effectively control the motor 21 to automatically stop driving.

[0063] In this embodiment, the control main board 10 is also provided with a third photoelectric detection device 204, which corresponds to the second locking position. The purpose of this is to enable the clutch module to be used on doors with different opening directions. That is to say, whether the lock core connecting shaft 92 rotates to the left or to the right, when it is rotated to the locking position, the automatic locking setting of the electronic lock can be realized, thereby improving the adaptability of the electronic lock clutch module and greatly improving the user experience.

[0064] In this embodiment, the clutch module of the electronic lock is also electrically connected to a wireless module, and the wireless module is used to connect to an external device. Specifically, the wireless module can be Bluetooth, WiFi, infrared, etc. Through the above structure, the user can use a remote control or a mobile phone APP to connect to the clutch module of the electronic lock through a wireless connection such as Bluetooth, WiFi or infrared, and can check the switch lock status of the electronic lock or control the opening or closing of the electronic lock at any time. The remote control operation saves the trouble of traditional mechanical keys, so that the electronic lock can be easily integrated into the smart home system, improving the overall intelligence level.

[0065] In this embodiment, the clutch module of the electronic lock is further provided with a housing 11, and the housing 11 protects various components therein, thereby protecting the components and preventing interference from other devices.

[0069] In this embodiment, the external lock body includes a mechanical lock core 210 and a fingerprint recognition device 220. The mechanical lock core 210 includes a lock core 211 into which a key is inserted and a lock bar 212 connected to the lock core and rotating synchronously;

[0070] The internal lock body 400 includes a clutch module 100 and a switch knob 410. The lock bar and the switch knob 410 are connected to the lock core connecting shaft in the clutch module 100 and rotate synchronously.

[0071] The door lock body 300 includes a bolt 310, wherein the bolt 310 includes a block 320. The bolt 310 is sleeved on the lock bar. The block 320 moves out or retracts as the lock bar 212 rotates. When the block 320 moves out, the electronic lock is in a locked state, and when the block is retracted, it is in an unlocked state.

[0072] Through the above structure, when the user presses the fingerprint recognition device 220, the control circuit board 10 in the clutch module 100 can receive the signal and start the motor to drive the clutch 5 to engage with the first meshing tooth 3 or the second meshing tooth 4, thereby driving the lock core connecting shaft 92 to rotate to the unlocking position and the locking position, thereby realizing automatic unlocking and locking functions; if the user does not want to use fingerprint unlocking, the key can be inserted into the lock core and the lock bar can be rotated to achieve the purpose of unlocking and locking; when the electronic lock fails, for example, the driving device cannot be driven after the electronic lock is out of power, the key can be inserted into the lock core or the switch knob 410 can be turned to unlock or lock, thereby ensuring that the electronic lock can use the mechanical unlocking function in the event of a power outage or failure, thereby ensuring the safety of the electronic lock.
