Description

Technical Field

[0001] The present invention relates to a door lock, and particularly to a clutch device and an electronic lock. Background Art

[0002] Some existing electronic locks include a grip, a clutch device, a transmission rod, and a door lock core. The transmission rod is rotatably arranged on the grip. The clutch device is installed inside the grip and can lock or unlock the position of the transmission rod relative to the grip. When the position of the transmission rod is locked, the user can twist the grip and control the door lock core through the transmission rod to open the door. The clutch device includes a base, a first clutch member, and a driving assembly. The first clutch member can telescopically move relative to the base. The driving assembly drives a driving member to rotate to a pushing position through a motor, and then pushes the first clutch member to extend out to lock the transmission rod by means such as plugging. At this time, the clutch device enters an engaged state and the electronic lock can be unlocked. After unlocking is completed, the motor needs to drive the driving member to rotate back to the starting position again to allow the first clutch member to retract. At this time, the clutch device enters a separated state and the electronic lock is locked. When the motor fails accidentally, the clutch device cannot be switched to the separated state, and the safety is insufficient. Summary of the Invention

[0034] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0035] Referring to Figures 1 to 6 , the clutch device 10 according to the embodiment of the present invention includes a base 100, a first clutch member 200, a driving assembly 300, and a repulsive force structure 400. The first clutch member 200 is disposed on the base 100 so as to be telescopic in the front-rear direction; the driving assembly 300 is disposed on the base 100, and the driving assembly 300 includes a rotation driver 310 and a driving member 320. The driving member 320 is rotatably disposed on the base 100 and is located at the rear side of the first clutch member 200. The rotation axis of the driving member 320 is disposed in the front-rear direction. The rotation driver 310 is configured to drive the driving member 320 to rotate. The driving member 320 has a starting position and a pushing position. When the driving member 320 rotates from the starting position to the pushing position, the driving member 320 can push the first clutch member 200 to move forward; when the driving member 320 rotates from the pushing position to the starting position, the first clutch member 200 can move backward; the repulsive force structure 400 is configured to drive the driving member 320 to rotate from the pushing position to the starting position.

[0036] In the separated state of the clutch device 10, the driving member 320 is in the starting position. When the clutch device 10 works, the rotation driver 310 rotates the driving member 320 to the pushing position, and pushes the first clutch member 200 to move forward to enter the engaged state; after the engaged state is used up, the repulsive force structure 400 directly rotates the driving member 320 to reset to the starting position, thereby allowing the first clutch member 200 to retreat, so that the clutch device 10 automatically enters the separated state without the rotation driver 310 rotating the driving member 320 to reset again. The accidental failure of the rotation driver 310 does not affect the clutch device 10 from entering the separated state, thereby improving safety.

[0037] Specifically, the base 100 is provided with a receiving hole 110 in the front-rear direction. The hole wall of the receiving hole 110 is provided with a guiding groove 120 in the front-rear direction. The driving member 320 is located in the receiving hole 110 and can rotate in the receiving hole 110. The first clutch member 200 is slidably connected to the receiving hole 110. The first clutch member 200 is provided with a guiding block 250. The guiding block 250 slidably penetrates through the guiding groove 120, so that the first clutch member 200 can slide back and forth.

[0038] Specifically, the rotation driver 310 is a motor that can control the rotation angle. It can be understood that in other embodiments, the rotation driver 310 can also be other types of structures that output rotational power, and those skilled in the art can specifically select according to actual needs.

[0039] In an embodiment, the repulsive structure 400 includes a first magnet 410 and a second magnet 420. The first magnet 410 is disposed on the first engaging member 200, and the second magnet 420 is disposed on the driving member 320. The repulsive force between the first magnet 410 and the second magnet 420 at the starting position is less than the repulsive force between the first magnet 410 and the second magnet 420 at the pushing position. The repulsive force between the first magnet 410 and the second magnet 420 at the pushing position is greater than the repulsive force between the first magnet 410 and the second magnet 420 at the starting position. The repulsive force automatically rotates the driving member 320 to the starting position, realizing the function of automatically rotating the driving member 320 from the pushing position to the starting position. The structure is simple and easy to implement.

[0040] In an embodiment, at the pushing position, the first magnet 410 and the second magnet 420 are opposite to each other front and back and repel each other; at the starting position, the first magnet 410 and the second magnet 420 are respectively located on opposite sides of the rotation axis of the driving member 320. When in the pushing position, the first magnet 410 and the second magnet 420 are opposite to each other front and back and repel each other. At this time, the repulsive force is the greatest, causing the driving member 320 to have a tendency to rotate away from the pushing position, causing the driving member 320 to rotate to the starting position. At this time, the first magnet 410 and the second magnet 420 are respectively disposed on opposite sides of the rotation axis of the driving member 320, and the repulsive force between the first magnet 410 and the second magnet 420 is the smallest. Thus, the driving member 320 is rotated to the reset position by magnetic repulsion, and the clutch device 10 automatically enters the separated state. The structure is simple and easy to implement.

[0041] Specifically, both the first magnet 410 and the second magnet 420 are magnets. At the pushing position, the first magnet 410 and the second magnet 420 are opposite in the same pole, so that there is a repulsive force between them. It can be imagined that in some other embodiments, the first magnet 410 and the second magnet 420 can also be electromagnets.

[0042] In an embodiment, a first convex portion 210 and a first concave portion 220 are provided on a side of the first engaging member 200 close to the driving member 320. The first convex portion 210 and the first concave portion 220 are arranged around the rotation axis of the driving member 320. A second convex portion 321 and a second concave portion 322 are provided on a side of the driving member 320 close to the first engaging member 200. The second convex portion 321 and the second concave portion 322 are arranged around the rotation axis of the driving member 320. At the starting position, the first convex portion 210 and the second concave portion 322 are opposite to each other front and back, and the first concave portion 220 and the second convex portion 321 are opposite to each other front and back; at the pushing position, the first convex portion 210 and the second convex portion 321 are opposite to each other front and back. A first pushing transition surface 230 is provided between the first convex portion 210 and the first concave portion 220, and a second pushing transition surface 323 is provided between the second convex portion 321 and the second concave portion 322.

[0043] When the driving member 320 rotates from the starting position to the pushing position, it is pushed by the first pushing transition surface 230 and the second pushing transition surface 323, causing the first clutch member 200 to move forward. Subsequently, the driving member 320 abuts against the first protruding portion 210 of the first clutch member 200 through the second protruding portion 321, keeping the first clutch member 200 protruding forward. When the driving member 320 rotates from the pushing position to the starting position, since the first protruding portion 210 and the first recessed portion 220 are opposite to each other front and back, and the second protruding portion 321 and the second recessed portion 322 are opposite to each other front and back, there is space to allow the first clutch member 200 to move backward, and finally the first protruding portion 210 is embedded in the first recessed portion 220, and the second protruding portion 321 is embedded in the second recessed portion 322.

[0044] It can be understood that only the first pushing transition surface 230 or the second pushing transition surface 323 can also be provided.

[0045] In the embodiment, both the first pushing transition surface 230 and the second pushing transition surface 323 are arc-shaped surfaces. The first pushing transition surface 230 is tangent to the bottom surface of the first recessed portion 220, and the second pushing transition surface 323 is tangent to the bottom surface of the second recessed portion 322, so that when the driving member 320 rotates from the starting position to the pushing position, it can smoothly push the first clutch member 200 to protrude forward, and the use effect is better.

[0046] It can be imagined that in other embodiments, both the first pushing transition surface 230 and the second pushing transition surface 323 can be inclined surfaces, and those skilled in the art can specifically select according to actual needs.

[0047] In the embodiment, the first magnet 410 is arranged on the first protruding portion 210, and the second magnet 420 is arranged on the second protruding portion 321, which can maximize the repulsive force at the pushing position and improve the effect of the driving member 320 rotating and resetting.

[0048] It can be imagined that in other embodiments, the first magnet 410 and the second magnet 420 can also be located at other positions of the driving member 320 and the first clutch member 200 respectively, and those skilled in the art can specifically select according to actual needs.

[0049] It can be imagined that in other embodiments, the first magnet 410 can also be arranged on the driving member 320, and the second magnet 420 can also be arranged on the base 100. When in the pushing position, the first magnet 410 and the second magnet 420 are in the closest position to each other; when in the starting position, the first magnet 410 and the second magnet 420 are in the farthest position from each other.

[0050] It is conceivable that in some other embodiments, the repulsive force structure 400 can also be in other forms. For example, the repulsive force structure 400 is a spring, one end of the spring is fixedly connected to the first clutch member 200, and the other end of the spring is fixedly connected to the driving member 320. When in the pushing position, the spring is compressed; when in the starting position, the spring is not compressed.

[0051] It can be understood that since there is a repulsive force structure 400 between the first clutch member 200 and the driving member 320, the contact friction between the first clutch member 200 and the driving member 320 is reduced, and there is also an effect of reducing the wear degree of the contact position between the first clutch member 200 and the driving member 320.

[0052] In an embodiment, the driving assembly 300 further includes an elastic reset member 330. The elastic reset member 330 is disposed between the base 100 and the first clutch member 200 and can drive the first clutch member 200 to move backward. When the driving member 320 is in the starting position, the elastic reset member 330 can drive the first clutch member 200 to move backward to realize the function of automatically switching the clutch device 10 to the disengaged state. The structure is simple and easy to implement.

[0053] Specifically, the elastic reset member 330 is a spring, one end of the spring abuts against the base 100, and the other end of the spring abuts against the first clutch member 200. It is conceivable that in some other embodiments, the elastic reset member 330 can also be structures such as a shrapnel or an elastic rubber block, etc. Those skilled in the art can specifically select according to actual needs.

[0054] The present invention also discloses an electronic lock, including a grip 20, the above-mentioned clutch device 10, and a transmission rod 30. The clutch device 10 is disposed on the grip 20; the transmission rod 30 is rotatably disposed on the grip 20, and the clutch device 10 can lock or unlock the position of the transmission rod 30 relative to the base 100. Due to the adoption of the above-mentioned clutch device 10, the electronic lock can have higher security.

[0055] In an embodiment, the electronic lock further includes a second clutch member 40. The second clutch member 40 is movably disposed in the grip 20 in the left-right direction. The first clutch member 200 is provided with an inclined top portion 240, and the second clutch member 40 is provided with an inclined top mating portion 41. The first clutch member 200 can push the inclined top mating portion 41 through the inclined top portion 240 to drive the second clutch member 40 to move. One end of the second clutch member 40 can abut against and fix the transmission rod 30. The clutch device 10 moves forward through the first clutch member 200, and the inclined top portion 240 of the first clutch member 200 abuts against the inclined top mating portion 41 of the second clutch member 40, so that the second clutch member 40 can move and press against the transmission rod 30, realizing the locking of the position of the transmission rod 30, so that the transmission rod 30 rotates synchronously with the grip 20; when the first clutch member 200 moves backward, the second clutch member 40 no longer applies a pressing force to the transmission rod 30, so that the grip 20 can rotate relative to the transmission rod 30 to achieve idle rotation. The setting of the second clutch member 40 is beneficial to making full use of the space of the grip 20 for layout and improving the use effect.

[0056] It can be imagined that in some other embodiments, it can also be directly through the first clutch member 200 to press against the transmission rod 30, and the position of the transmission rod 30 relative to the grip 20 can also be locked or unlocked.

[0057] It can be imagined that in some other embodiments, the transmission rod 30 can also be fixedly connected with a connection disk. When the first clutch member 200 expands and contracts, it can be inserted into or disengaged from the insertion hole on the connection disk. When the first clutch member 200 is inserted into the insertion hole, the positions of the transmission rod 30 and the connection disk relative to the grip 20 are locked; when the first clutch member 200 disengages from the insertion hole, the transmission rod 30 and the connection disk can rotate relative to the grip 20.

[0058] In the embodiment, both the inclined top portion 240 and the inclined top mating portion 41 are conical surfaces, and the way to realize the inclined top is relatively simple and the use is more flexible. It can be imagined that in some other embodiments, both the inclined top portion and the inclined top mating portion 41 can be inclined surfaces or arc surfaces.

[0059] In the embodiment, it further includes a clutch lock core 50. The clutch lock core 50 is disposed in the grip 20. The clutch lock core 50 is rotatably provided with a dial block 51. The rotation axis of the dial block 51 is perpendicular to the front-rear direction. The clutch lock core 50 can push the first clutch member 200 to move forward through the dial block 51. The clutch lock core 50 is disposed at the grip 20. When the key is inserted into the clutch lock core 50, the key can drive the dial block 51 to rotate, and the dial block 51 directly pushes the first clutch member 200 to move forward, thereby realizing the locking of the transmission rod 30, allowing the grip 20 to drive the transmission rod 30 to rotate synchronously to unlock. The setting of the clutch lock core 50 is beneficial to realizing manual unlocking when the rotation driver 310 fails, improving the use convenience.

[0060] Specifically, the guiding block 250 is provided with a rod body portion, and the shifting block 51 abuts against the rod body portion, which is convenient for structural layout. It can be imagined that in some other embodiments, a connecting rod may also be provided. One end of the connecting rod is pivotally connected to the shifting block 51, and the other end is pivotally connected to the first clutch member 200. When the shifting block 51 rotates, the first clutch member 200 can be pushed to move by the connecting rod.

[0061] Specifically, a battery module and a fingerprint module are further provided in the electronic lock. The battery module can supply power to the clutch device 10, and the fingerprint module can be used to detect the fingerprint of the user to control the operation of the clutch device.

[0062] Specifically, the grip 20 is spherical.
