Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of the technical solutions appears contradictory or unachievable, it should be considered that the combination of the technical solutions does not exist, and is not within the protection scope required by the present application.

[0066] Please refer to Figures 1 to 3 The present application proposes a lock, which can be used for locking a cabinet body, and can also be used for locking a door, and can also be used for other objects that need to be locked, which is not limited here.

[0067] The lock includes an unlocking assembly 100, an electrical unlocking module 200, a mechanical unlocking module 300, and a locking module 400. The electrical unlocking module 200 and the mechanical unlocking module 300 are in transmission connection with the unlocking assembly 100. The locking module 400 acts on the mechanical unlocking module 300. The unlocking assembly 100 can be formed by one component or by a plurality of components combined together, which is not specifically limited here.

[0068] The electrical unlocking module 200 drives the unlocking assembly 100 to rotate for unlocking or locking when receiving an unlocking signal or a locking signal. The unlocking signal can be sent by an authorized certificate, by a control background, or by an unlocking chip, which is not specifically limited here.

[0069] The mechanical unlocking module 300 drives the unlocking assembly 100 to rotate for unlocking or locking under the rotation of a mechanical key. The locking module 400 is used for limiting the mechanical unlocking module 300 when receiving a locking signal, so that the mechanical unlocking module 300 cannot perform unlocking operation, or releasing the limitation on the mechanical unlocking module 300 when receiving a release signal, so that the mechanical unlocking module 300 can perform unlocking operation.

[0070] The locking module 400 can limit the mechanical unlocking module 300 in many ways. The locking module 400 can limit the unlocking module by extension and retraction, or by rotation. The locking module 400 can also limit the mechanical unlocking module 300 in other ways, which is not specifically limited here. The release signal can be sent by a control background or by the electrical unlocking module 200, which is not specifically limited here.

[0071] When unlocking the lock, the staff sends an unlocking signal to the electrical unlocking module 200, so that the electrical unlocking module 200 drives the unlocking assembly 100 to rotate, thereby unlocking the lock. When locking the lock, the staff sends a locking signal to the electrical unlocking module 200, so that the electrical unlocking module 200 drives the unlocking assembly 100 to rotate, thereby locking the lock, or the lock generates a locking signal after being in an unlocked state for a period of time, thereby driving the unlocking assembly 100 to rotate, and further locking the lock.

[0072] When the electrical unlocking fails to complete the unlocking of the lock, the staff needs to send a release signal to the locking module 400 first, and then drive the unlocking assembly 100 to rotate by the mechanical key and the mechanical unlocking module 300, thereby unlocking the lock.

[0073] When the power failure causes the electrical unlocking module 200 to fail to work normally, so that the electrical unlocking module 200 cannot complete unlocking, the electrical unlocking module 200 sends an unlocking signal to the mechanical unlocking module 300 before the power failure, so that the locking module 400 releases the limit of the mechanical unlocking module 300, and then the worker can drive the unlocking assembly 100 to rotate by cooperating with the mechanical key and the mechanical unlocking module 300 to unlock the lock.

[0074] When locked by the mechanical unlocking module 300, the worker first drives the unlocking assembly 100 to rotate by cooperating with the mechanical key and the mechanical unlocking module 300, so that the lock is locked, and then sends a locking signal to the locking module 400, so that the locking module 400 limits the mechanical unlocking module 300.

[0075] Under certain use requirements, the locking module 400 can keep the state of releasing the limit of the mechanical unlocking module 300, so that the worker can directly unlock the lock by the mechanical key.

[0076] The technical scheme of the present application limits the mechanical unlocking module 300 by the locking module 400, the electrical unlocking module 200 is drivingly connected with the unlocking assembly 100 to drive the unlocking assembly 100 to rotate for unlocking or locking when receiving the unlocking signal or the locking signal, the mechanical unlocking module 300 is drivingly connected with the unlocking assembly 100 to drive the unlocking assembly 100 to rotate for unlocking or locking under the rotation of the mechanical key, and the locking module 400 is used for limiting the mechanical unlocking module 300 when receiving the locking signal, so that the mechanical unlocking module 300 cannot perform unlocking operation, or releasing the limit of the mechanical unlocking module 300 when receiving the unlocking signal, so that the mechanical unlocking module 300 can perform unlocking operation. By limiting the mechanical unlocking module 300 by the locking module 400, the limit of the mechanical unlocking module 300 is released only when the locking module 400 receives the unlocking signal, so that the key cannot be illegally copied to cause the lock to be opened by irrelevant personnel, thereby improving the safety performance of the lock.

[0077] Please see Figures 1 to 3 In some embodiments of the present application, the locking module 400 includes a driving assembly 410, a locking rod 420, and a first controller, the locking rod 420 is drivingly connected with the driving assembly 410, and the locking rod 420 limits or releases the limit of the mechanical unlocking module 300 under the driving of the driving assembly 410;

[0078] The first controller is electrically connected with the driving assembly 410 and the control background. When the first controller receives the locking signal or the unlocking signal, the first controller controls the driving assembly 410 to work, so as to control the locking rod 420 to limit or release the mechanical unlocking module 300.

[0079] In this way, when the first controller receives the locking signal or the unlocking signal, the driving assembly 410 drives the locking rod 420 to move to limit or release the rotating lug 320, so that the control background needs to send the unlocking signal to the first controller when the mechanical key is used to open the lock, thereby avoiding that irrelevant personnel opens the lock by the mechanical key.

[0080] It should be noted that the driving assembly 410 can be a telescopic motor, the driving assembly 410 can also be a gas pump, the driving assembly 410 can also be other structures for driving the locking rod 420 to stretch out or retract, which are not limited here. The driving assembly 410 can be directly driven by a motor to rotate the locking rod 420, the driving assembly 410 can also be composed of an electrode and a gear, the driving assembly 410 can also be a structure for driving the locking rod 420 to rotate, which are not limited here.

[0081] Specifically, the mechanical unlocking module 300 includes a lock cylinder 310 and a rotating lug 320, one end of the rotating lug 320 is in transmission connection with the lock cylinder 310, and the other end of the rotating lug 320 is in transmission connection with the unlocking assembly 100; the locking rod 420 limits or releases the rotating lug 320 under the drive of the driving assembly 410.

[0082] In this way, when the first controller receives the locking signal or the unlocking signal, the driving assembly 410 drives the locking rod 420 to move to limit or release the rotating lug 320, the rotating lug 320 is in transmission connection with the unlocking assembly 100, so that the locking rod 420 limiting the rotating lug 320 can make the mechanical key unable to drive the rotating lug 320 to rotate through the lock cylinder 310, thereby avoiding that irrelevant personnel opens the lock by the mechanical key.

[0083] Specifically, please refer to Figures 1 to 5 The driving assembly 410 is located on one side of the rotating lug 320 in the axial direction, and a limiting groove 321 is recessed in the circumferential side of the rotating lug 320; one end of the locking rod 420 away from the driving assembly 410 is provided with a limiting portion 421 in plug connection with the limiting groove 321, and the locking rod 420 rotates under the drive of the driving assembly 410 to make the limiting portion 421 extend into or out of the limiting groove 321. In this way, the limiting portion 421 is controlled to extend into or out of the limiting groove 321 by rotating the locking rod 420, so as to control the locking rod 420 to limit or release the rotating lug 320, and the driving member 210, the locking rod 420 and the lock cylinder 310 are on the same axis, thereby reducing the occupation space of the lock in the radial direction of the lock cylinder 310, and improving the universality of the lock.

[0084] Further, please refer to Figures 1 to 5 The surface of the lug 320 facing the driving assembly 410 is concave with a movable groove 322 extending in the circumferential direction of the lug 320, and the groove wall of the movable groove 322 in the radial direction of the lug 320 is concave with a limiting groove 321, and one end of the locking rod 420 away from the driving assembly 410 extends into the movable groove 322. In this way, the locking rod 420 is arranged in the movable groove 322, and the locking rod 420 and the two wall surfaces of the movable groove 322 in the circumferential direction of the lug 320 are in abutment, thereby limiting the rotation amplitude of the lug 320, and further limiting the rotation amplitude of the unlocking shaft 110, and the occupation space of the lock in the radial direction of the lock cylinder 310 can be further reduced, thereby improving the universality of the lock.

[0085] Please refer to Figures 1 to 9 In some embodiments of the present application, the mechanical unlocking module 300 further comprises a transmission sheet 330 located between the lug 320 and the unlocking assembly 100, the transmission sheet 330 is in transmission connection with the unlocking assembly 100, and the surface of the transmission sheet 330 facing the lug 320 is convex with a first transmission part 331; the surface of the lug 320 facing the transmission sheet 330 is concave with a first transmission groove 323, and the first transmission part 331 is located in the first transmission groove 323; the lock cylinder 310 drives the lug 320 to rotate under the rotation of the mechanical key, and the groove wall of the first transmission groove 323 is in abutment with the first transmission part 331 to drive the transmission sheet 330 to rotate.

[0086] In this way, when the mechanical key is rotated in cooperation with the lock cylinder, the rotation of the lock cylinder drives the lug to rotate, so that the groove wall of the first transmission groove 323 is in abutment with the first transmission part 331 to drive the transmission sheet 330 to rotate, and the transmission sheet 330 drives the unlocking assembly 100 to rotate, and the unlocking assembly 100 is driven to rotate by the electrical unlocking module 200, and the rotation of the unlocking assembly 100 drives the transmission sheet 330 to rotate, and the lug 320 is limited by the locking module 400, so that the lug 320 cannot rotate, and the electrical unlocking module 200 cannot continue to drive the lug 320 to rotate after the first transmission part 331 is in abutment with the groove wall of the first transmission groove 323, thereby limiting the rotation amplitude of the unlocking shaft 110.

[0087] Specifically, please refer to Figures 1 to 9The unlocking assembly 100 comprises an unlocking shaft 110 and a transmission member 120, the unlocking shaft 110 is in transmission connection with the transmission member 120, and the transmission member 120 is provided with a second transmission part 121 protruding towards the surface of the transmission sheet 330; the transmission sheet 330 is provided with a second transmission groove 332 recessed towards the surface of the unlocking assembly 100, and the second transmission part 121 extends into the second transmission groove 332; the transmission sheet 330 rotates, and the groove wall of the second transmission groove 332 abuts against the second transmission part 121 to drive the transmission member 120 to rotate, so as to drive the unlocking shaft 110 to rotate.

[0088] In this way, the lug 320 is in transmission connection with the unlocking shaft 110 through the transmission sheet 330 and the transmission member 120, and when the electrical unlocking module 200 drives the unlocking shaft 110 to rotate, the unlocking shaft 110 rotates to drive the transmission sheet 330 and the transmission member 120 to rotate, and since the lug 320 is limited by the locking module 400, the lug 320 cannot rotate, and thus after the first transmission part 331 abuts against the groove wall of the first transmission groove 323, the electrical unlocking module 200 cannot continue to drive the lug 320 to rotate, so that the rotation range of the unlocking shaft 110 is limited.

[0089] Please refer to Figures 1 to 10 In some embodiments of the present application, the mechanical unlocking module 300 further comprises a fixing sheet 340 located between the transmission member 120 and the lug 320, the fixing sheet 340 is provided with an avoiding hole 341, and the hole wall of the avoiding hole 341 is provided with a limiting protrusion 341a; the transmission sheet 330 is located in the avoiding hole 341, and the circumferential side of the transmission sheet 330 is provided with a limiting groove 333 extending along the circumference of the transmission sheet 330, and the limiting protrusion 341a extends into the limiting groove 333.

[0090] In this way, when the transmission member 120 rotates to abut against the limiting groove 333, the transmission member 120 cannot continue to rotate, so that the rotation range of the transmission member 120 is limited, and the rotation range of the unlocking shaft 110 is limited.

In this way, the fixing sheet 340 cooperates with the locking rod 420 through the mounting hole 343, so that the fixing sheet 340 is limited in the circumference by the locking rod 420, and the structure for fixing the fixing sheet 340 is reduced, so that the structure of the lock is more compact, and the volume of the lock is reduced.

[0111] It should be noted that there are many ways to use the locking module 400, for example, when the electrical unlocking module 200 is damaged and cannot be used, the second identity authentication locking module 400 receives a release signal to release the limit of the mechanical unlocking module 300, thereby allowing the lock to be unlocked by the mechanical key and the mechanical unlocking module 300; for example, when the mechanical unlocking module 300 needs to be used for a long time, the second identity authentication locking module 400 receives a release signal to release the limit of the mechanical unlocking module 300 for a long time, thereby allowing the staff to unlock the lock at any time by the mechanical key and the mechanical unlocking module 300, which is not limited here.

[0112] In some embodiments of the present application, the electrical unlocking module 200 is electrically connected with the locking module 400, and the operation method of the lock further comprises:

[0113] acquiring the remaining power of the electrical unlocking module;

[0114] if the power of the electrical unlocking module is insufficient;

[0115] sending a release signal to the locking module through the electrical unlocking module to make the locking module work;

[0116] releasing the mechanical unlocking module by the locking module;

[0117] rotating the mechanical unlocking module by the mechanical key to drive the unlocking assembly to move, so that the lock is unlocked.

[0118] In this way, when the electrical unlocking module 200 is out of power, the locking module 400 will receive the release signal sent by the electrical unlocking module 200, so that the locking module 400 will timely release the mechanical unlocking module 300, and then the relevant personnel can unlock the lock through the mechanical key, so that when the electrical unlocking module 200 is out of power and cannot be opened, the relevant personnel cannot timely unlock the lock.
