[0049] The first mounting member 11 is provided with a first locking portion 111, and the second mounting member 12 is provided with a second locking portion 121, the first locking portion 111 and the second locking portion 121 are arranged close to the clutch assembly 2; the driving assembly 4 includes a pushing portion 4521 movably arranged in the movable channel 13, the pushing portion 4521 is arranged in an arc shape, and the pushing portion 4521 is used to drive the locking member 3 to move between the locking position and the unlocking position, when in the locking position, the pushing portion 4521, the first locking portion 111, and the second locking portion 121 cooperatively form a locking section for locking the locking member 3.

[0050] The clutch assembly 2 is externally connected with an operation handle 7, the operation handle 7 is used to unlock the cabinet through the clutch assembly 2, when the operation handle 7 drives the clutch assembly 2 to rotate, the locking section can make the locking member 3 be in the locking position, and the clutch assembly 2 is in the linkage state, so that the clutch assembly 2 can be engaged and disengaged, and the operation handle 7 can drive the clutch assembly 2 to rotate for unlocking operation, which meets the normal unlocking operation requirement of the idle cabinet lock and improves the use performance of the idle cabinet lock.

[0051] When the pushing portion 4521 moves away from the first locking portion 111 and the second locking portion 121, that is, moves away from the clutch assembly 2, the pushing portion 4521 can reopen the movable channel 13, when the operation handle 7 drives the clutch assembly 2 to return to the position of locking the cabinet, the pushing portion 4521 no longer limits the locking member 3, the locking member 3 can partially move into the movable channel 13, the locking member 3 returns to the unlocking position, the locking of the clutch assembly 2 is released, the clutch assembly 2 is in the disengaged state, and the operation handle 7 can only freely rotate relative to the shell 1 and cannot perform unlocking operation through the clutch assembly 2.

[0052] Referring to Figures 4 to 6 The driving assembly 4 comprises a mounting shell 41, a motor 42, a transmission assembly 43, a pushing piece 44 and a push plate assembly 45. The motor 42 and the transmission assembly 43 are arranged in the mounting shell 41, and the pushing piece 44 and the push plate assembly 45 are movably connected to the mounting shell 41. The motor 42 drives the pushing piece 44 to move through the transmission assembly 43, so that the pushing piece 44 drives the push plate assembly 45 to move. The push plate assembly 45 has a pushing part 4521, and the push plate assembly 45 drives the locking piece 3 to move between the locking position and the unlocking position through the pushing part 4521. The motor 42 is electrically connected to the control panel 6, and the control panel 6 can receive an unlocking instruction or a locking instruction.

[0053] When the cabinet is unlocked, the control panel 6 receives an unlocking instruction from the system or an external terminal device. The control panel 6 controls the motor 42 to work based on the unlocking instruction. The motor 42 drives the pushing piece 44 to move through the transmission assembly 43. The pushing piece 44 moves and drives the pushing assembly to move. When the pushing assembly moves, the pushing part 4521 pushes the locking piece 3 to move, so that the locking piece 3 locks the clutch assembly 2, so that the clutch assembly 2 is in the linkage state. The operating handle 7 can drive the whole clutch assembly 2 to move, and then the cabinet is unlocked.

[0054] When the cabinet is locked, the control panel 6 receives a locking instruction from the system or an external terminal device. The control panel 6 controls the motor 42 to work based on the locking instruction. The motor 42 drives the pushing piece 44 to move back through the transmission assembly 43. The pushing piece 44 moves and drives the pushing assembly to move back. When the pushing assembly moves back, the pushing part 4521 releases the limiting of the locking piece 3. The locking piece 3 retreats to the unlocking position, so as to release the locking of the clutch assembly 2. The clutch assembly 2 is in the separation state. The operating handle 7 can only freely rotate relative to the shell 1, and cannot be unlocked through the clutch assembly 2. In this way, the cabinet is locked.

[0055] The push plate assembly 45 comprises a first push plate 451, a second push plate 452 and a first elastic piece 453. The middle regions of the first push plate 451 and the second push plate 452 are hollow. The pushing piece 44 is arranged in the first push plate 451 and the second push plate 452. The first elastic piece 453 is arranged in the hollow region of the first push plate 451. One end of the spring abuts against the pushing piece 44, and the other end abuts against the first push plate 451. The pushing piece 44 synchronously drives the first push plate 451 and the second push plate 452 to move through the first elastic piece 453.

[0056] When the motor 42 drives the pusher 44 to move through the transmission assembly 43, the pusher 44 compresses the first elastic member 453, and the first push plate 451 and the second push plate 452 are driven to move synchronously under the action of the first elastic member 453. In this way, when the first elastic member 453 has enough power, the motor 42 can stop working, and the first push plate 451 and the second push plate 452 can be driven to move only under the action of the first elastic member 453, so that the flexible unlocking can be realized under the premise that the pushing part 4521 can normally push the locking piece 3 into the locked position, thereby avoiding the situation that the locking piece 3 cannot be inserted into the clutch assembly 2 when the operating handle 7 does not return to the unlocking position, and the motor 42 is blocked.

[0057] The first push plate 451 and the second push plate 452 are stacked, and the first push plate 451 is arranged below the second push plate 452 to save space and improve the compactness of the structure.

[0058] The mounting shell 41 includes a first shell 411 and a second shell 412, which are assembled together and cooperatively form a cavity for mounting the motor 42 and the transmission assembly 43. The second shell 412 is provided with a moving channel, and the first push plate 451 is movably arranged in the limiting channel 4121. The second shell 412 is also provided with a hole body 4122 communicating with the internal cavity and the limiting channel 4121, and the transmission assembly 43 partially extends out of the hole body 4122 to be connected with the first push plate 451. The transmission assembly 43 includes a bevel gear 431 and a worm gear 432. The bevel gear 431 is fixedly connected with the motor 42, and the bevel gear 431 is in meshing connection with the worm gear 432. The worm gear 432 is provided with an eccentric boss 4321 extending out of the hole body 4122, and the eccentric boss 4321 is connected with the pusher 44. The worm gear 432 drives the pusher 44 to reciprocate through the eccentric boss 4321 during rotation.

[0059] Referring to Figures 4 to 9 , the push plate assembly 45 further includes a second elastic member 454. The first push plate 451 is provided with a mounting groove 4511, and the second push plate 452 is provided with a stop block 4522 arranged in the mounting groove 4511. The second elastic member 454 is arranged in the mounting groove 4511, one end of the second elastic member 454 abuts against the stop block 4522, and the other end of the second elastic member 454 abuts against the groove wall of the mounting groove 4511. The second push plate 452 can freely move relative to the first push plate 451. The pushing part 4521 is formed at one end of the second push plate 452 facing the locking piece 3, and the pushing part 4521 is arranged in the form of an arc-shaped plate.

[0060] When the pusher 44 drives the first push plate 451 and the second push plate 452 to move synchronously, the pusher 44 drives the first push plate 451 to move through the first elastic member 453, and the first push plate 451 drives the second push plate 452 to move through the groove wall of the mounting groove 4511, so that the first push plate 451 and the second push plate 452 can move synchronously.

[0061] When the second push plate 452 moves freely relative to the first push plate 451, the second push plate 452 compresses the second elastic member 454, and in this case, mechanical unlocking can be performed without affecting the first elastic member 453. By setting the first elastic member 453 and the second elastic member 454, only the first elastic member 453 acts when the motor 42 is driven, and the second elastic member 454 does not act; only the second elastic member 454 acts when mechanical unlocking is performed, and the first elastic member 453 does not act. In this way, the unlocking in the two cases does not affect each other, so as to improve the reliability and stability when unlocking in the respective cases.

[0062] The first elastic member 453 and the second elastic member 454 can both be springs. When the first elastic member 453 is a spring, one end of the spring is sleeved on the limiting protrusion of the push member 44, and the other end is sleeved on the limiting protrusion of the first push plate 451, so as to stably install the first elastic member 453.

[0063] With reference to Figures 4 to 9 The idling cabinet lock further comprises an emergency unlocking lock cylinder 8 arranged in the shell 1. The emergency unlocking lock cylinder 8 is provided for an external emergency unlocking key to be inserted. The emergency unlocking lock cylinder 8 is used to drive the second push plate 452 to move relative to the first push plate 451 when an external force acts, so that the second push plate 452 drives the locking member 3 to move between the locking position and the unlocking position.

[0064] Through the emergency unlocking lock cylinder 8, emergency unlocking of the cabinet can be performed when the motor 42 cannot be driven, so as to ensure that the user can normally unlock the cabinet.

[0065] The idling cabinet lock further comprises a control panel 6 electrically connected with the motor 42. The control panel 6 is provided with a first micro switch 61, a second micro switch 62, and a third micro switch 63. The push member 44 is provided with a first triggering portion 441. The push plate assembly 45 comprises the second push plate 452, and the second push plate 452 is provided with a second triggering portion 4523. The first micro switch 61, the second micro switch 62, and the third micro switch 63 are distributed along the movement path of the first triggering portion 441. The first triggering portion 441 is arranged between the first micro switch 61 and the second micro switch 62. The first triggering portion 441 triggers the first micro switch 61, and the second triggering portion 4523 triggers the third micro switch 63 when the control panel 6 controls the motor 42 to stop working. When the second triggering portion 4523 triggers the second micro switch 62, the control panel 6 controls the motor 42 to stop working.

[0066] When the cabinet needs to be unlocked, the control board 6 receives an unlocking instruction and controls the motor 42 to start.

The first push plate 451 and the second push plate 452 are driven by the pusher 44 to move towards the locking piece 3. When the first trigger part 441 triggers the first micro switch 61 and the second trigger part 4523 triggers the third micro switch 63, the control board 6 controls the motor 42 to stop working. The push part 4521 pushes the locking piece 3 to insert into the clutch assembly 2, so that the clutch assembly 2 is in a linkage state, and the cabinet can be unlocked.

[0067] In addition, when the unlocking time exceeds the set time, the system will issue a locking instruction to the control board 6. The control board 6 controls the motor 42 to start again based on the locking instruction. The motor 42 drives the pusher 44 to move back through the transmission assembly 43, and drives the first push plate 451 and the second push plate 452 to move back. The push part 4521 can make the locking piece 3 return to the unlocking position, and the clutch assembly 2 is in a separated state, so as to complete the locking of the cabinet.

[0068] When the emergency unlocking is performed, the operation handle 7 is lifted, the awakened key is inserted into the emergency unlocking lock cylinder 8, and the key is rotated to the bottom. The key drives the paddle of the emergency unlocking lock cylinder 8 to rotate. The paddle drives the second push plate 452 to move relative to the first push plate 451. Until the second trigger part 4523 triggers the third micro switch 63, and the first trigger part 441 always keeps triggering the second micro switch 62, the push part 4521 pushes the locking piece 3 to insert into the clutch assembly 2, so that the clutch assembly 2 is in a linkage state, and the cabinet can be unlocked.

[0069] Referring to Figures 4 to 9 The clutch assembly 2 includes a shaft sleeve 21 and a rotating shaft 22. The rotating shaft 22 is rotatably arranged in the shaft sleeve 21. The shaft sleeve 21 is provided with a first locking hole 211. The locking piece 3 is movably arranged in the first locking hole 211. The rotating shaft 22 is provided with a second locking hole 221. In the linkage state, the locking end of the locking piece 3 extends out of the first locking hole 211 and extends into the second locking hole 221. The rotating shaft 22 and the shaft sleeve 21 can synchronously rotate relative to the shell 1. In the separated state, the locking end of the locking piece 3 exits the second locking hole 221. The rotating shaft 22 can freely rotate relative to the shell 1.

[0070] In this way, the shaft sleeve 21 and the rotating shaft 22 can synchronously rotate in the linkage state. In the separated state, the rotating shaft 22 can independently rotate relative to the shaft sleeve 21. The rotating shaft 22 is connected with the operation handle 7. The operation handle 7 can only rotate relative to the shell 1 and cannot be unlocked, so as to achieve the locking of the cabinet.

[0071] The locking piece 3 comprises a locking body 31 and an elastic body 32, the elastic body 32 is sleeved on the locking body 31, the first locking hole 211 is formed with an annular block near the opening of the second locking hole 221, one end of the elastic body 32 abuts against the annular block, and the other end abuts against a stepped portion of the outer peripheral wall of the locking body 31. The elastic body 32 can be a spring.

[0072] In the locking position, the pushing portion 4521 pushes the locking body 31 to compress the elastic body 32 and extend into the second locking hole 221, and the rotating shaft 22 and the shaft sleeve 21 are in linkage to rotate synchronously; in the unlocking position, the pushing portion 4521 retreats, the locking body 31 is popped out of the second locking hole 221 under the action of the elastic body 32, and the rotating shaft 22 and the shaft sleeve 21 are in separation, so that the operation handle 7 can only idle relative to the shell 1 and cannot be unlocked, so as to realize the locking of the cabinet.

[0073] The shell 1 can comprise a front shell 14, a rear shell 15 and an assembly shell 16, the front shell 14 and the rear shell 15 jointly accommodate the installation and clutch assembly 2, the locking piece 3, the driving assembly 4 and the anti-pinch assembly 5. The operation handle 7 is rotationally connected to the front shell 14, and the assembly shell 16 is connected to the rear shell 15 and is used for being mounted on the cabinet.

[0074] The above is only optional embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields under the inventive concept of the present application, or the contents of the present application are included in the patent protection range of the present application.
