2. The motor lock according to claim 1, characterized in that: The hook assembly (5) is capable of rotating around the hook shaft (15). A push spring (53) is provided on the hook assembly (5). When unlocking, the push spring (53) is compressed; when locking, the push spring (53) is no longer compressed but returns to its original shape, driving the hook assembly (5) to rotate in the locking direction, so that the hook assembly (5) is engaged with the rack assembly (2).

3. The motor lock according to claim 2, characterized in that: The hook assembly (5) comprises a hook body (51), an arcuate groove (54) is provided on one side of the hook body (51) close to the rack assembly (2), a sliding limit column (24) is provided on the rack assembly (2), and the arcuate groove (54) cooperates with the sliding limit column (24).

4. The motor lock according to claim 3, characterized in that: The rack assembly (2) includes a push plate (21), a guide rail (22) and a rack structure (23); the rack structure (23) is mounted on the guide rail (22); the rack structure (23) is slidably connected to the guide rail (22); the push plate (21) is mounted on one end of the rack structure (23); the other end of the rack structure (23) is meshedly connected to the motor assembly (9); and the sliding limit column (24) is mounted on the push plate (21).

5. The motor lock according to claim 4, characterized in that: The motor assembly (9) comprises a motor body (91) and a gear (93). The motor assembly (9) is connected to an external controller and a power source via a connecting line. The gear (93) is mounted on the motor shaft of the motor body (91). The gear (93) is meshed with the rack structure (23).

6. The motor lock according to claim 5, characterized in that: The motor lock comprises a cover body (1), a first limiting column (13) is provided on the cover body (1), and a sliding groove (211) is provided on the push plate (21); When unlocking, the push plate (21) is driven by the motor assembly (9) to move toward the lock pin (71) and extend out of the cover body (1), and the first limiting column (13) can limit the sliding groove (211) to stop the push plate (21) from moving; When the lock is closed, the push plate (21) moves into the cover body (1) in a direction away from the lock pin (71) driven by the motor assembly (9); the first limiting column (13) can limit the sliding groove (211) to stop the push plate (21) from moving; When the lock is closed in an emergency, the push plate (21) is pushed to move it in a direction away from the lock pin (71) and into the cover body (1); the first limiting column (13) can limit the sliding groove (211) to stop the push plate (21) from moving.

7. The motor lock according to claim 6, characterized in that: A first pressing block (231) in a convex shape is provided on the rack structure (23). When the door is locked, the first pressing block (231) is tightly fitted with the first micro switch (81), forming a circuit breaker and feeding back to the main control board, and the motor assembly (9) stops moving, thereby outputting the door opening signal and the door opening state; When unlocking, the first pressing block (231) is tightly fitted with the second micro switch (82), forming a circuit breaker and feeding back to the main control board, and the motor assembly (9) stops moving, thereby outputting the door closing signal and the door closing state.

8. The motor lock according to claim 7, characterized in that: The motor lock further comprises an emergency rod (56), an emergency opening (14) is provided on the cover body (1), and the emergency rod (56) extends out of the cover body (1) from the emergency opening (14). During emergency unlocking, the emergency lever (56) is pushed to rotate in the unlocking direction, releasing the locking of the rack assembly (2) on the hook assembly (5), and the hook assembly (5) and the lock pin (71) are separated from each other, thus achieving emergency unlocking.

9. The motor lock according to claim 8, characterized in that: The hook assembly (5) includes a key sheet (52), the key sheet (52) is mounted on the hook body (51), one end of the key sheet (52) is in contact with or separated from the lock pin (71), and the other end of the key sheet (52) is in contact with or separated from the third micro switch (83); When the lock is closed, one end of the key piece (52) contacts the lock pin (71), and the other end of the key piece (52) separates from the third micro switch (83) to form a circuit break and feedback to the main control board, thereby realizing the judgment that the items in the storage device (7) are locked in place.

10. The motor lock according to claim 1, characterized in that: The motor lock further comprises an infrared photoelectric distance sensing switch (41), wherein the infrared photoelectric distance sensing switch (41) is capable of judging the access of items in the storage device (7) within a sensing distance d; When the distance between the object and the motor lock is greater than the sensing distance d, the infrared photoelectric distance sensing switch (41) sensing light turns off and feeds back to the main control board, thereby realizing the object taking judgment.
