[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] See Figures 1 to 5As shown, an electronic lock clutch structure includes a drive structure 1 and a clutch structure 2. In this embodiment, the clutch structure includes a clutch fork 21, a clutch pin 22, a handle fixing plate 23 and a reset spring 24. During assembly, the handle fixing plate is connected to the door handle, and the clutch fork is connected to the square shaft. In this embodiment, the handle fixing plate and the door handle are fixed by screws. The handle fixing plate and the clutch fork are overlapped, and the two ends of the reset spring are respectively connected to the clutch fork and the handle fixing plate. At the same time, in actual application, a pin groove 3 is provided on the edge of the handle fixing plate, and an N-shaped protrusion 4 is provided on the side of the clutch fork. The edge of the handle fixing plate is attached to the inner end of the N-shaped protrusion. During use, under the action of the return spring, the handle fixing plate and the clutch fork are aligned with the pin groove and the recessed area of ​​the N-shaped protrusion. The clutch pin is connected to the drive structure, and under the action of the drive structure, the clutch pin is locked into the N-shaped protrusion and the pin groove, thereby connecting the handle fixing plate and the clutch fork as a whole. Due to the above structure, when the drive structure is not in operation, the clutch pin is separated from the handle fixing plate, at which time the door handle can drive the handle fixing plate to rotate, achieving a reverse locking operation. When the electronic lock is verified, the drive structure is activated and drives the clutch pin to translate, causing a portion of the clutch pin's end edge to be locked into the pin groove and the other portion to be located in the recessed area of ​​the N-shaped protrusion. At this time, the handle fixing plate and the clutch fork are connected as a whole, that is, the two can rotate synchronously, and the clutch fork drives the square shaft to rotate to complete the unlocking operation, thereby improving the safety and reliability of use and enhancing practicality.

[0029] In actual application, the driving structure includes a driving motor 11, a telescopic shaft and a semicircular retaining member 12; and the inner end of the telescopic shaft is arranged in the driving motor, and the semicircular retaining member is fixed to the outer end of the telescopic shaft; the operation of the driving motor can make the telescopic shaft extend and retract, and drive the semicircular retaining member to move horizontally. In this embodiment, the semicircular retaining member is a plastic structure.

[0030] The surface of the semicircular stopper is provided with an arcuate guide groove 5. When in use, one end of the clutch pin is located in the arcuate guide groove, and the other end of the clutch pin is located in the recessed area of ​​the n-shaped protrusion, and the clutch pin is separated from the pin-positioning groove. The semicircular stopper extends, driving the clutch pin to move and causing the end of the clutch pin to engage with the pin-positioning groove. The arcuate guide groove can guide the clutch pin and prevent it from separating from the semicircular stopper.

[0031] Furthermore, in actual application, the clutch pin has a stepped pin body. The length of the clutch end is greater than the depth of the pin groove. The length of the clutch end is less than or equal to the length of the N-shaped protrusion. With this structure, when the clutch pin translates, it can simultaneously engage with the pin groove and the recessed area of ​​the N-shaped protrusion.

[0032] The present invention has positive effects: the structure of the present invention is reasonably arranged, and its clutch structure includes a clutch fork, a clutch pin, a handle fixing plate and a reset spring, and cooperates with the driving structure, which can not only realize the connection and positioning of the door handle, but also quickly realize the connection and positioning of the square shaft, and in the normal state, the clutch pin does not enter the pin position groove at the edge of the handle fixing plate. At this time, the handle fixing plate can rotate but will not drive the clutch pin to rotate. When the driving structure is actuated, the end of the clutch pin is driven from the recessed area of ​​the N-shaped protrusion to the pin position groove, and the N-shaped protrusion is connected to the pin position groove through the clutch pin. At this time, the rotation of the handle fixing plate can drive the clutch fork to rotate synchronously, thereby realizing the unlocking action, improving the stability and reliability of use, and improving the safety and effectiveness of use, and having strong practicality.

[0033] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0034] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
