When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0029] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature identified with "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0031] Please also refer to Figures 1 to 5 The unlocking mechanism provided by an embodiment of the present invention will now be described. This unlocking mechanism is used to rotate a crank arm 330 within the lock body 300 to unlock the lock. The crank arm 330 herein refers to a swinging structure installed within the lock body 300 that drives the latch bolt 350 backward into the lock body 300. The unlocking mechanism includes a clutch assembly 100 and a rotating assembly 200.

[0032] The clutch assembly 100 is disposed within the lock body 300 and includes a normally open member 110 and two clutch members 120. Both the clutch members 120 and the normally open member 110 are capable of abutting against a crank arm 330. The normally open member 110 is disposed between the two clutch members 120. Specifically, the abutment of the two clutch members 120 and the normally open member 110 with the crank arm 330 means that the two clutch members 120 and the normally open member 110 contact end surfaces that facilitate rotation of the crank arm 330. Rotation of the first and second clutch members 120, 120, and the normally open member 110 drives rotation of the crank arm 330. This rotation of the crank arm 330 drives the latch bolt 350 to retract into the interior of the lock body 300, thereby unlocking the lock.

[0033] The normally open member 110 is provided with a normally open mating hole 111 which is set through, opened in the front-to-back direction, and has a non-circular cross-sectional shape. The clutch member 120 is provided with a clutch mating hole 121 which is set through, opened in the front-to-back direction, and has a non-circular cross-sectional shape. Specifically, the square hole is opened at the center of the first clutch member 120, the second clutch member 120, and the normally open member 110. Since the projections of the square holes in the front-to-back direction overlap, the shape and size of each square hole are the same; the cross-sectional shape of the square hole can be square, rectangular, or rhombus, or the cross-sectional shape of the square hole can be pentagonal. In short, any cross-sectional shape that can easily drive the first clutch member 120, the second clutch member 120, and the normally open member 110 to rotate is within the scope of consideration of the present invention. Furthermore, by projecting and overlapping the square holes on the first clutch member 120, the second clutch member 120 and the normally open member 110 in the front-to-back direction, the rotating assembly 200 that cooperates with the clutch assembly can be inserted into the clutch assembly 100 from one side of the first clutch member 120 or from one side of the second clutch member 120.

[0034] Rotating assembly 200 includes a normally open connector 210 and a clutch connector 220. Normally open connector 210 includes a normally open external connection portion 211, a normally open avoidance portion 212, and a normally open adapter portion 213, which are sequentially connected. Normally open adapter portion 213 is located in normally open mating hole 111 and drives the corresponding clutch member 120 to rotate during rotation. Normally open avoidance portion 212 is located in a clutch mating hole 121 and avoids the corresponding clutch mating hole 121 during rotation. Specifically, normally open external connection portion 211 is connected to the inside door handle. When the inside door handle is rotated, it can drive normally open connector 210 to rotate. However, because normally open avoidance portion 212 avoids the clutch mating hole 121, normally open connector 210 cannot drive clutch member 120 to rotate, thereby driving latch 350 in lock body 300 to unlock the door from the inside. It should be noted that the normally open member 110 can be rotated at any time by driving the crank arm 330 through the inner handle of the revolving door, ensuring that the door can be opened at any time by people inside.

[0035] The clutch connector 220 includes a clutch external connection portion 221 and a clutch adapter portion 222, which are interconnected. The clutch adapter portion 222 is located in the other clutch mating hole 121 and drives the corresponding clutch member 120 to rotate during rotation. The clutch connector 220 is a square shaft structure with a cross-sectional shape that matches the clutch mating hole 121. The clutch adapter portion 222 is inserted into the clutch mating hole 121 and engages with the clutch member 120. Specifically, the clutch connector 220 engages with the clutch mating hole 121 of one of the two clutch members 120. When the clutch connector 220 is engaged with the clutch mating hole 121, the clutch mating hole 121 in the clutch member 120 can restrict the clutch connector 220 from axial rotation. The clutch external connection part 221 is used to connect with the outer handle of the door. When the clutch 120 in the lock body 300 is in the locked state, the outer handle of the door cannot be rotated, and the clutch external connection part 221 connected to the outer handle of the door cannot drive the clutch 120 to rotate. When the clutch 120 in the lock body 300 is in the unlocked state, by rotating the outer handle of the door, the clutch connection part 220 connected to the outer handle of the door can engage with the clutch matching hole 121 in the clutch 120, so the clutch connection part 220 can drive the clutch 120 to rotate, thereby driving the inclined tongue 350 to retreat to complete the unlocking of the door from the outside.

[0036] Compared with the prior art, the unlocking mechanism provided by the present invention is provided in the electronic lock of the present invention. The normally open connecting member 210 in the unlocking mechanism can be inserted into the normally open matching hole 111 from the outside of any clutch member 120 to ensure that the person inside the door can normally open the door. The clutch connecting member 220 can also be inserted into the clutch matching hole 121 from the outside of any clutch member 120 to ensure that the person outside the door needs electricity to unlock the door. The lock body 300 of the electronic lock equipped with the above-mentioned clutch assembly 100 only needs to be flipped over to achieve the ability to be installed on both the inward-opening door and the outward-opening door, thereby solving the technical problem of poor versatility of the lock body 300.

[0037] See also Figure 1 as well as Figure 3 As a specific embodiment of the unlocking mechanism provided by the present invention, the lower ends of the two clutch members 120 are each provided with a card interface 122, with the projections of the card interfaces 122 overlapping in the front-to-back direction. By providing two card interfaces 122, both card interfaces can engage with the paddles of the motor 310 in the lock body 300. This prevents the clutch member 120 from rotating unless the paddles of the motor 310 are disengaged from the two card interfaces 122, thus preventing the exterior door handle connected to the clutch member 120 from directly unlocking the door. The overlap of the two card interfaces 122 in the front-to-back direction provides a more stable structure when the card interfaces 122 engage the paddles of the motor 310.

[0038] Referring to Figure 1 , as a specific embodiment of the unlocking mechanism provided by the present invention, the clutch assembly 100 further includes a boss 130 disposed on each of the two clutch members 120. Each boss 130 is disposed on the outer end surface of its corresponding clutch member 120 and has a positioning hole formed therein. The boss 130 facilitates insertion of the clutch connector 220 or the normally open connector 210 into the square hole, achieving a positioning function for the insertion of the clutch connector 220 and the normally open connector 210, thereby improving the ease of assembly of the rotating assembly 200.

[0039] See also Figure 1 As a specific embodiment of the unlocking mechanism provided by the present invention, the positioning hole is connected to the clutch matching hole 121, and the projection of the positioning hole in the front-to-back direction overlaps with the clutch matching hole 121, ensuring that the normally open connector 210 and the clutch connector 220 can be smoothly inserted into the clutch matching hole 121, and can also improve the structural stability of the normally open connector 210 and the clutch connector 220 after being inserted into the clutch matching hole 121.

[0040] See also Figure 1 and Figure 3 As a specific embodiment of the unlocking mechanism provided by the present invention, a groove 123 is formed on the end surface of each clutch member 120 near the normally open member 110. Two protrusions 112 are formed on the two end surfaces of the normally open member 110 near each clutch member 120. Each protrusion 112 is engaged with its corresponding groove 123, and the normally open mating hole 111 extends through both protrusions 112. By providing the groove 123 on each clutch member 120 and the two protrusions 112 on the two end surfaces of the normally open member 110, when assembling the clutch assembly 100, the two clutch members 120 can be first snapped together on both sides of the normally open member 110. Each clutch member 120 and the normally open member 110 are not likely to slip off, ensuring a certain snap connection between the clutch members 120 and the normally open member 110, thereby improving the convenience of assembling the clutch assembly 100.

[0041] See also Figure 1 As a specific embodiment of the unlocking mechanism provided by the present invention, the clutch member 120 and the normally open member 110 are both sheet-like structures.

[0042] See also Figure 2 As a specific embodiment of the unlocking mechanism provided by the present invention, one of the two clutch members 120 is attached to the front end surface of the normally open member 110, and the other of the two clutch members 120 is attached to the rear end surface of the normally open member 110. By attaching the clutch members 120 to the normally open member 110, the volume of the clutch assembly 100 in the front-to-back direction is reduced, making the structure of the clutch assembly 100 more compact.

[0043] See also Figure 2 As a specific embodiment of the unlocking mechanism provided by the present invention, a rotation space 140 is formed between the two clutch members 120, and the normally open member 110 is disposed in the rotation space 140. By disposing the normally open member 110 in the rotation space 140, the normally open member 110 can be protected and the normally open member 110 can be easily rotated between the two clutch members 120.

[0044] See also Figure 1 As a specific embodiment of the unlocking mechanism provided by the present invention, the clutch mating hole 121 overlaps the front-to-back projections of the normally-open mating hole 111. This arrangement facilitates manufacturing and allows for universal use of the clutch assembly 100 after the lock body 300 is flipped over.

[0045] See also Figure 1 As a specific embodiment of the unlocking mechanism provided by the present invention, the first clutch member 120, the second clutch member 120 and the normally open member 110 are bilaterally symmetrical along a central axis.

[0046] See also Figure 1 as well as Figure 5 The present invention also provides an electronic lock, which includes a lock body 300, the lock body 300 including a motor 310, a paddle of the motor 310, a crank arm 330, a switching structure 340 and a latch bolt 350, and the lock body 300 also includes the above-mentioned unlocking mechanism.

[0047] The electronic lock provided by the present invention adopts a lock body 300 having the above-mentioned unlocking mechanism. By flipping the lock body 300, the lock body 300 can be used on both inward-opening doors and outward-opening doors, thereby improving the versatility of the electronic lock.

[0048] Among them, the unlocking process of the inner-opening door or outer-opening door assembled with the lock body 300 is as follows: the person inside the door rotates the inner handle connected to the normally-open connecting member 210, thereby driving the normally-open member 110 to rotate, and the rotation of the normally-open member 110 will drive the crank arm 330 to swing to drive the adapter structure 340 to drive the inclined bolt 350 to retreat, thereby achieving unlocking; the person outside the door first needs to input magnetic induction information to the lock body 300. When the motor 310 in the lock body 300 receives the magnetic induction information, the motor 310 drives the motor 310 paddle to disengage the card interface 122. At this time, by rotating the outer handle connected to the clutch connecting member 220, the clutch member 120 is driven to rotate. The rotation of the clutch member 120 will drive the crank arm 330 to swing to drive the inclined bolt 350 to retreat, thereby achieving unlocking for the person outside the door.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
