[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a dual-clutch structure for a lock, such as Figs. 1-3 As shown, the lock includes a clutch disc 1 with several grooves on its outer surface. A mechanical latch 7 is located at the upper part of the clutch disc 1, and a clutch latch 2 is located at the lower part. The mechanical latch 7 and clutch latch 2 can be inserted into the grooves to achieve synchronized unlocking. The dual-clutch structure is encapsulated within the lock housing 8. The mechanical latch 7 is mechanically driven, while the clutch latch 2 is electrically driven. The grooves on the outer surface of the clutch disc 1 cooperate with the mechanical latch 7 at the upper part and the clutch latch 2 at the lower part. The mechanical latch 7 is mechanically driven, while the clutch latch 2 is electrically driven; both can be inserted into the grooves of the clutch disc 1 to achieve synchronized unlocking. The entire dual-clutch structure is encapsulated within the lock housing 8, protecting the internal structure and resulting in a neat and aesthetically pleasing overall appearance.

[0029] First, the dual-clutch structure provides a double safety mechanism, enhancing the lock's security. Second, the combination of mechanical and electric drives improves the ease of use, meeting unlocking needs in various scenarios. Finally, the overall structure is compact and rationally designed, easy to package and install, reducing manufacturing costs and maintenance difficulties. Therefore, the dual-clutch lock structure of this invention has significant technical advantages and practical value.

[0030] In this embodiment, when the mechanical latch 7 and the clutch latch 2 leave the groove, the clutch disc 1 is in an idle state. When both the mechanical latch 7 and the clutch latch 2 leave the groove of the clutch disc 1, the clutch disc 1 can rotate freely and is in an idle state. This design ensures the flexibility of the lock in the unlocked state, while also providing the necessary mechanical freedom for the normal use of the lock.

[0031] Specifically, the mechanical bolt 7 moves forward and backward by inserting a key into the mechanical lock cylinder 3, which in turn drives the mechanical drive component 6. This mechanical transmission mechanism is simple and reliable, ensuring that the mechanical bolt 7 can accurately insert into or disengage from the groove of the clutch disc 1, thereby achieving the mechanical locking and unlocking functions of the lock.

[0032] Furthermore, it also includes a telescopic motor 4, whose output shaft is equipped with a motor drive component 5. The telescopic motor 4 drives the motor drive component 5 to reciprocate, thereby controlling the forward and backward movement of the clutch bolt 2. Through the cooperation of the telescopic motor 4 and the motor drive component 5, electric forward and backward control of the clutch bolt 2 is achieved. This electric drive mechanism improves the convenience of the lock, allowing users to remotely control the locking and unlocking of the lock via remote control or touch.

[0033] Furthermore, the groove shape of the clutch disc 1 is adapted to the shapes of the clutch bolt 2 and the mechanical bolt 7, ensuring that the bolts can be stably inserted and engaged. This design improves the stability and reliability of the lock, ensuring its normal operation during long-term use.

[0034] Furthermore, one end of the clutch latch 2 is provided with a latch, which engages with one side of the motor drive component 5. This engagement mechanism ensures that the motor drive component 5 can accurately drive the clutch latch 2 to move forward and backward, improving the accuracy and stability of the electric drive mechanism.

[0035] Furthermore, the mechanical lock cylinder 3 drives the mechanical drive component 6 to rotate, and the mechanical bolt 7 slides vertically within the lock housing 8. A protrusion is installed on one side of the mechanical bolt 7. The rotation of the mechanical drive component 6, by actuating the protrusion, achieves the vertical movement of the mechanical bolt 7, thereby causing the bottom end of the mechanical bolt 7 to engage with the groove in the clutch disc 1. The mechanical lock cylinder 3 drives the mechanical drive component 6 to rotate, and by actuating the protrusion on one side of the mechanical bolt 7, achieves the vertical movement of the mechanical bolt 7 within the lock housing 8. This mechanical transmission mechanism ensures that the mechanical bolt 7 can accurately engage with the groove in the clutch disc 1, realizing the mechanical locking function of the lock.

[0036] Furthermore, the clutch disc 1 has four outer grooves arranged in a ring with equal spacing. This design provides multiple bolt insertion positions, enhancing the lock's adaptability and flexibility. Simultaneously, the equal spacing ensures the lock's stability and balance in the locked state.

[0037] The dual-clutch structure of this invention, when in use, primarily comprises a clutch disc 1, a mechanical latch 7, a clutch latch 2, and a lock housing 8. The outer surface of the clutch disc 1 has several (four in this embodiment) grooves for engaging with the mechanical latch 7 and the clutch latch 2. The mechanical latch 7 is located on the upper part of the clutch disc 1 and is mechanically driven; the clutch latch 2 is located on the lower part of the clutch disc 1 and is electrically driven. The entire dual-clutch structure is encapsulated within the lock housing 8, protecting the internal structure and maintaining a clean appearance. Initially, the mechanical latch 7 and the clutch latch 2 may be in a position away from the grooves, and the clutch disc 1 is in a free-spinning state.

[0038] When mechanical locking is required, the user inserts the key into the mechanical lock cylinder 3. The mechanical lock cylinder 3 drives the mechanical drive component 6 to rotate. As the mechanical drive component 6 rotates, it actuates a protrusion on one side of the mechanical bolt 7, causing the mechanical bolt 7 to move vertically within the lock housing 8. The bottom end of the mechanical bolt 7 gradually engages a groove in the clutch disc 1, achieving mechanical locking. To unlock, the user rotates the mechanical lock cylinder 3 in the opposite direction using the key. The mechanical drive component 6 drives the mechanical bolt 7 to move in the opposite direction, disengaging it from the groove in the clutch disc 1, and the clutch disc 1 returns to its free-spinning state.

[0039] When electric locking is required, the control system sends a command to the telescopic motor 4. The output shaft of the telescopic motor 4 drives the motor drive component 5 to reciprocate. The motor drive component 5 engages with the latch at one end of the clutch tongue 2, driving the clutch tongue 2 to move forward and backward. The clutch tongue 2 gradually engages with another groove in the clutch disc 1, achieving electric locking. When unlocking, the control system sends a reverse command to the telescopic motor 4, and the motor drive component 5 drives the clutch tongue 2 to move in the opposite direction, disengaging it from the groove in the clutch disc 1.

[0040] Both the mechanical latch 7 and the clutch latch 2 can be independently inserted into the groove of the clutch disc 1 to achieve locking. When both are inserted into the groove simultaneously, the lock is in a double-locked state, providing higher security. The shape of the groove of the clutch disc 1 is adapted to the shape of the mechanical latch 7 and the clutch latch 2, ensuring that the latches can be stably inserted and engaged.

[0041] The clutch disc 1 has four outer grooves arranged in a ring with equal spacing. This design provides multiple bolt insertion positions, enhancing the lock's adaptability and flexibility. The equal spacing also ensures the lock's stability and balance when locked.

[0042] Finally, it should be noted that the electronic components in the above-mentioned components, such as the telescopic motor 4 in this embodiment, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.
