[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0023] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0024] Reference Figures 1 to 4 An electronic spherical lock's clutch and unlocking structure includes an outer cover 1 installed on the outside of the door, a front ball 2 mounted on the outer cover 1, the front ball 2 including a housing 3 and an end cap 4 mounted on the housing 3, a locking groove 6 provided in the center of the outer cover 1, an unlocking motor 5 installed in the housing 3 corresponding to the locking groove 6, a locking rod 7 slidably mounted on the unlocking motor 5 and reset by a return spring 23, the locking rod 7 being inserted into the locking groove 6. After the door is closed, it does not automatically switch between locked and unlocked states; switching between locked and unlocked states requires control by the unlocking motor, with the locking rod inserting or retracting from the locking groove. This is more suitable for frequent entry and exit situations, and the structure is simpler than that of conventional smart door locks.

[0025] In this product, the front ball 2 and the matching lock cylinder are always connected (this structure is existing technology). That is, as long as the front ball 2 can be turned, the bolt of the lock cylinder will be moved back into the lock cylinder. In other words, whether this product is locked depends on whether the locking rod 7 is inserted into the locking groove 6. When the locking rod 7 is inserted into the locking groove 6, the product is locked; otherwise, it is unlocked.

[0026] A sliding frame 8, which is reset by the reset spring 23, is slidably mounted on the rotating shaft of the unlocking motor 5. The rotating shaft is located inside the sliding frame 8 and has a protrusion 9. The protrusion 9 is inserted into the reset spring 23 from the side. The locking rod 7 is fixedly mounted on the end of the sliding frame 8 away from the unlocking motor 5. When the rotating shaft rotates, it drives the protrusion 9 to rotate synchronously, causing the protrusion 9 to slide spirally on the reset spring 23, causing the reset spring 23 to slide along the axis of the rotating shaft, thereby causing the sliding frame 8 to slide on the rotating shaft, and finally causing the locking rod 7 to insert into or retract from the locking groove 6.

[0027] The sliding frame 8 is provided with a sliding groove 10, and the upper locking rod 7 is provided with a sliding part 11 corresponding to the sliding groove 10. The sliding part 11 is inserted into the sliding groove 10.

[0028] The housing 3 houses a motor housing 12, and the unlocking motor 5 is fixedly mounted on the motor housing 12. An unlocking plate 14, controlled by a mechanical lock cylinder 13, is slidably mounted on one side of the motor housing 12. The unlocking plate 14 has a hook portion 15 folded towards the sliding frame 8. The hook portion 15 abuts against the upper inner surface of the sliding frame 8. The mechanical lock cylinder 13 is opened with a key, causing the unlocking plate 14 to slide on the motor housing 12. The hook portion 15 causes the sliding frame 8 to slide synchronously, ultimately causing the locking rod 7 to disengage from the locking groove 6, achieving mechanical unlocking with the key. This is generally used in emergencies, such as when the product's power is depleted.

[0029] When mechanical unlocking is performed using a key, as the sliding frame 8 slides on the rotating shaft, the return spring 23 is gradually compressed. When the key is turned in the opposite direction, the return spring 23 pushes the sliding frame 8 to reset, thereby causing the locking rod 7 to re-insert into the locking groove 6, achieving the locking effect.

[0030] The motor housing 12 is provided with a sliding groove 16, and the unlocking piece 14 is provided with a sliding part 17 corresponding to the sliding groove 16. The sliding part 17 is slidably installed in the sliding groove 16.

[0031] A mounting base 18 is installed on the end face of the housing 3, and the mechanical lock cylinder 13 is installed on the mounting base 18.

[0032] The bottom of the mounting base 18 is equipped with a control board 21 that is electrically connected to the unlocking motor 5, and the end cover 4 is equipped with a decoding disk 22 that is electrically connected to the control board 21.

[0033] The decoding disk 22 is one of a fingerprint decoding disk and a password decoding disk.

[0034] The mechanical lock cylinder 13 is provided with a cam part 19, and the unlocking plate 14 is provided with a strip hole 20 corresponding to the cam part 19. The cam part 19 is movably installed in the strip hole 20. The two ends of the strip hole 20 are semi-circular arcs. When the cam part 19 rotates, the cam part 19 slides along the inner edge of the strip hole 20, thereby causing the unlocking plate 14 to slide along the axis of rotation.

[0035] The keyhole of the mechanical lock cylinder 13 is located directly below the front ball 2, concealing the keyhole. This not only improves the aesthetics of the product but also prevents strangers from discovering the keyhole and thus committing illegal acts.

[0036] This product also includes a battery, which is electrically connected to the control board 21 to provide power to the decoding disk 22 and the unlocking motor 5, etc.
