Description

TECHNICAL FIELD

[0001] The present application relates to the field of locks, in particular, to an intelligent cabinet lock. BACKGROUND

[0002] A cabinet lock is a lock used to protect the safety of equipment in a cabinet. It is usually used in cabinets, server racks, network equipment cabinets, or other cabinets that require physical security control. The main function of a cabinet lock is to prevent unauthorized access and ensure that equipment is not stolen or damaged.

[0003] A cabinet lock generally unlocks the cabinet by rotating the handle and locks the cabinet by locking the handle to the lock body to limit the rotation of the handle. Existing cabinet locks use a resilient member to provide a resilient force to the handle of the cabinet lock to pop the handle away from the lock body of the cabinet lock when the handle is released, so that the operator can unlock the cabinet by turning the handle. However, during the process of the handle being popped away from the lock body of the cabinet lock, the handle is likely to collide with the operator's hand, causing the operator to be injured or the unlocking module (such as a computer key, a mobile phone, etc.) to be damaged. CONTENT OF THE UTILITY MODEL

[0004] The embodiments of the present application provide an intelligent cabinet lock, which can reduce the risk of the handle colliding with the operator's hand during the process of the handle being popped away from the lock body of the cabinet lock, causing the operator to be injured or the unlocking module to be damaged.

[0005] The embodiments of the present application provide an intelligent cabinet lock, which includes a lock body, a handle assembly, a first resilient member, an electronic locking assembly, and a resilient limiting member. The handle assembly is movably connected to the lock body, and has a stowed position and a popped-out position. The first resilient member is used to provide a resilient force to the handle assembly to drive the handle assembly to rotate from the stowed position to the popped-out position. The electronic locking assembly is arranged in the lock body. When the handle assembly is located at the stowed position and the electronic locking assembly locks the handle assembly, the intelligent cabinet lock is in a locked state. When the handle assembly is located at the popped-out position and / or the electronic locking assembly releases the handle assembly, the intelligent cabinet lock is in an unlocked state. The resilient limiting member is arranged in the lock body. During the process of the first resilient member driving the handle assembly to rotate from the stowed position to the popped-out position, the handle assembly abuts against the resilient limiting member and is kept at an intermediate position between the stowed position and the popped-out position.

[0006] In the technical scheme, in the process that the first elastic member drives the handle assembly to rotate from the stowed position to the popped position, the handle assembly abuts against the elastic limiting member and is kept at the intermediate position between the stowed position and the popped position. Specifically, when the operator releases the handle assembly by placing the unlocking module (such as a computer key, a mobile phone, etc.) close to the intelligent cabinet lock so that the electronic locking assembly releases the handle assembly, the elastic limiting member can limit the handle assembly at the intermediate position. After the operator stows the unlocking module, the operator can hold the handle assembly by hand and apply an external force to the handle assembly to drive the elastic limiting member to elastically deform and drive the handle assembly to continue to rotate to the popped position. Thus, compared with the case that the handle assembly rotates from the stowed position to the popped position without stopping, the risk that the handle assembly collides with the operator's hand and causes the operator to be injured or the unlocking module to be damaged is reduced.

[0007] In some embodiments, the handle assembly has a first end and a second end arranged oppositely, the first end is movably connected to the lock body; the lock body has a receiving groove; when the handle assembly is at the stowed position, the second end is located in the receiving groove; when the handle assembly is at the popped position, the second end is located outside the receiving groove; and the elastic limiting member is arranged on a groove wall of the receiving groove.

[0008] In the technical scheme, the elastic limiting member is arranged on the groove wall of the receiving groove, so that no additional connecting structure needs to be arranged on the lock body, the volume of the lock body is reduced, and thus the volume of the intelligent cabinet lock having the lock body is reduced.

[0009] In some embodiments, an outer peripheral surface of the second end is provided with a convex part, and the convex part abuts against the elastic limiting member when the handle assembly is at the intermediate position.

[0010] In the technical scheme, the convex part abuts against the elastic limiting member, compared with the case that the outer peripheral surface of the second end directly abuts against the elastic limiting member, the stroke of the second end abutting against the elastic limiting member in the process that the first elastic member drives the handle assembly to rotate from the stowed position to the popped position is reduced, so that the stroke of the operator overcoming the elastic deformation force of the elastic limiting member to drive the handle assembly to rotate is reduced, the size of the work required to drive the handle assembly to move from the intermediate position to the popped position is reduced, and thus the operator can hold the handle assembly by hand and apply an external force to the handle assembly to drive the handle assembly to continue to rotate to the popped position.

[0011] In some embodiments, the elastic limiting member is a bumping bead.

[0012] In the technical scheme, the elastic limiting member is arranged as a bumping bead, the versatility of the elastic limiting member is increased, the replacement of the elastic limiting member is facilitated, and thus the manufacturing and maintenance of the intelligent cabinet lock are facilitated.

[0013] In some embodiments, the electronic locking assembly comprises a housing, a latch and a driving assembly. The housing is arranged in the lock body; the latch is telescopically connected to the housing, the latch has a locking position and an unlocking position; in the locking position, the latch extends out of the housing to lock the handle assembly in the stowed position, so that the intelligent cabinet lock is in the locked state; in the unlocking position, the latch retracts into the housing to release the handle assembly in the stowed position, so that the intelligent cabinet lock is in the unlocked state; the driving assembly is used to drive the latch to switch between the locking position and the unlocking position.

[0014] In the above technical solution, the driving assembly can drive the latch to switch between the unlocking position and the locking position. Specifically, when the latch is in the locking position and the handle assembly is in the stowed position, the latch can lock the handle assembly on the lock body, so that the intelligent cabinet lock is in the locked state; when the latch is switched from the locking position to the unlocking position, the handle assembly in the stowed position is released, so that the handle assembly is no longer locked on the lock body, and at this time the first elastic member provides an elastic force to the handle assembly to drive the handle assembly to rotate from the stowed position to the popped-out position, so that the intelligent cabinet lock is in the unlocked state. Thus, by controlling the extension and retraction of the latch, the handle assembly is locked on or separated from the lock body, so that the intelligent cabinet lock is in the locked state or the unlocked state, thereby improving the reliability of the intelligent cabinet lock.

[0015] In some embodiments, the intelligent cabinet lock further comprises a control circuit board and a wireless power supply assembly. The control circuit board is arranged in the lock body and is electrically connected with the driving assembly; the wireless power supply assembly is arranged in the lock body, and the control circuit board is electrically connected with the unlocking module through the wireless power supply assembly to receive the first signal and the electric energy of the unlocking module, and the control circuit board responds to the first signal to provide electric energy to the driving assembly to switch the latch between the locking position and the unlocking position.

[0016] In the above technical solution, by arranging the control circuit board and the wireless power supply assembly in the lock body, and electrically connecting the control circuit board with the unlocking module through the wireless power supply assembly to receive the first signal and the electric energy of the unlocking module, compared with the case where the control circuit board is connected with an external power supply, no additional power supply line is needed, and no additional hole is needed on the lock body for the power supply line, thereby simplifying the structure of the lock body and increasing the integrity of the intelligent cabinet lock; compared with the case where the control circuit board is connected with a built-in power supply, the number of parts that need to be maintained and replaced during maintenance and repair is reduced, thereby simplifying the maintenance and repair process and facilitating the maintenance of the operator.

[0017] In some embodiments, the intelligent cabinet lock further comprises a Hall element and a magnetic element. The Hall element is arranged in the lock body and electrically connected with the control circuit board; the magnetic element is arranged in the handle assembly, and the Hall element is used to detect the distance between the magnetic element and the Hall element to detect the position information of the handle assembly.

[0018] In the above technical solution, the position information of the handle assembly is detected by the Hall element and the magnetic element, which is simple in structure and easy to implement.

[0019] In some embodiments, the handle assembly comprises a handle body and a locking element. One end of the handle body is movably connected to the lock body; the locking element is rotatably connected to the other end of the handle body, the rotation axis of the locking element is perpendicular to the extension direction of the handle body, the locking element has an emergency locking position and an emergency unlocking position; when the locking element is located at the emergency locking position and the bolt is located at the locking position, the bolt locks the locking element, so that the intelligent cabinet lock is in the locked state; when the bolt is located at the unlocking position and / or the locking element is located at the emergency unlocking position, the bolt is separated from the locking element, so that the intelligent cabinet lock is in the unlocked state.

[0020] In the above technical solution, when the locking element is located at the emergency unlocking position, the bolt is separated from the locking element, so that the intelligent cabinet lock is in the unlocked state, thereby in an emergency situation (such as when the unlocking module is powered off or the control circuit board is damaged), the operator can unlock the intelligent cabinet lock by adjusting the position of the locking element to repair the equipment in the intelligent cabinet.

[0021] In some embodiments, the handle assembly further comprises a lock cylinder. One end of the lock cylinder is arranged in the handle body, and the locking element is arranged at the output end of the lock cylinder, and the output end of the lock cylinder is used to drive the locking element to switch between the emergency locking position and the emergency unlocking position.

[0022] In the above technical solution, the locking element is driven by the lock cylinder to switch between the emergency locking position and the emergency unlocking position, on the one hand, the risk of accidental touch causing the locking element to switch between the emergency locking position and the emergency unlocking position is reduced; on the other hand, only the key that needs to be adapted can drive the driving end of the lock cylinder to rotate, thereby increasing the reliability of the intelligent cabinet lock and reducing the risk of unauthorized access and equipment theft or damage.

[0023] In some embodiments, the handle assembly further comprises a rotating shaft. One end of the rotating shaft is rotatably arranged in the interior of the lock body; the other end of the handle body away from the locking element is rotatably arranged at the other end of the rotating shaft located outside the lock body, and the rotation axis of the rotating shaft is perpendicular to the rotation axis of the handle body.

[0024] In the above technical solution, one end of the rotating shaft is rotatably arranged inside the lock body; the end of the handle body away from the locking member is rotatably arranged at the other end of the rotating shaft outside the lock body, so that in the pop-up position, the operator can rotate the end of the handle body away from the rotating shaft around the rotating axis of the rotating shaft to drive the rotating shaft to rotate, and then drive the structural member (such as a steel bolt or a top and bottom rod) connected with the rotating shaft to unlock or lock the cabinet, which is simple in structure and easy to realize.

[0055] In the embodiments of the present application, the same reference signs represent the same parts, and for the sake of brevity, the detailed description of the same parts is omitted in different embodiments. It should be understood that the thickness, length and width of various components in the embodiments of the present application shown in the drawings, and the overall thickness, length and width of the integrated device are only exemplary and should not constitute any limitation on the present application.

[0056] In this application, "multiple" means two or more (including two).

[0057] A rack lock is a type of lock used to protect the equipment inside a server rack. It is typically used in server racks, network equipment racks, or other enclosures requiring physical security control. The primary function of a rack lock is to prevent unauthorized access and ensure that equipment is not stolen or damaged. Rack locks generally unlock by rotating a handle and lock the rack by locking the handle to the lock body to restrict its rotation. Existing rack locks use elastic elements to provide a spring force to the handle, so that when the handle is released, it springs away from the lock body, allowing the operator to unlock the rack by turning the handle. However, during this process, the handle can easily collide with the operator's hand, causing injury or damage to the unlocking module (such as computer keys, mobile phones, etc.).

[0058] Based on the above considerations, in order to reduce the risk of injury to the operator or damage to the unlocking module caused by the handle colliding with the operator's hand during the process of the handle popping off the lock body, this application provides an intelligent cabinet lock including a lock body, a handle assembly, a first elastic member, an electronic locking assembly, and an elastic limiting member. The handle assembly is movably connected to the lock body and has a retracted position and an extended position; the first elastic member provides elastic force to the handle assembly to drive the handle assembly to rotate from the retracted position to the extended position; the electronic locking assembly is disposed in the lock body; when the handle assembly is in the retracted position and the electronic locking assembly locks the handle assembly, the intelligent cabinet lock is in a locked state; when the handle assembly is in the extended position and / or the electronic locking assembly releases the handle assembly, the intelligent cabinet lock is in an unlocked state; the elastic limiting member is disposed in the lock body; during the process of the first elastic member driving the handle assembly to rotate from the retracted position to the extended position, the handle assembly abuts against the elastic limiting member and remains in an intermediate position between the retracted position and the extended position.

[0059] In this type of smart cabinet lock, during the rotation of the handle assembly from the retracted position to the pop-out position driven by the first elastic element, the handle assembly abuts against the elastic limiting element and remains in an intermediate position between the retracted and pop-out positions. Specifically, when the operator brings the unlocking module (such as a computer key, mobile phone, etc.) close to the smart cabinet lock to release the handle assembly by the electronic locking component, the elastic limiting element can restrain the handle assembly in the intermediate position. After the operator retracts the unlocking module, they can hold the handle assembly by hand and apply external force to the handle assembly to cause the elastic limiting element to deform elastically and drive the handle assembly to continue rotating towards the pop-out position. This reduces the risk of injury to the operator or damage to the unlocking module caused by the handle assembly colliding with the operator's hand, compared to the situation where the first elastic element drives the handle assembly to rotate from the retracted position to the pop-out position without stopping.

[0060] The intelligent cabinet lock is described in detail below with reference to the accompanying drawings.

[0061] Please refer to Figure 1 , and please refer to Figures 2-4 , Figure 1 The structural explosion diagram of the intelligent cabinet lock 100 provided for some embodiments of the present application, Figures 2-4 The cross-sectional view of the intelligent cabinet lock 100 provided for some embodiments of the present application when the handle assembly 20 is located at the stowed position, the intermediate position and the popped-out position respectively. The present application provides an intelligent cabinet lock 100, which comprises a lock body 10, a handle assembly 20, a first elastic member 30, an electronic locking assembly 40 and an elastic limiting member 50. The handle assembly 20 is movably connected to the lock body 10, and the handle assembly 20 has a stowed position and a popped-out position. The first elastic member 30 is used to provide an elastic force to the handle assembly 20 to drive the handle assembly 20 to rotate from the stowed position to the popped-out position. The electronic locking assembly 40 is arranged in the lock body 10. When the handle assembly 20 is located at the stowed position and the electronic locking assembly 40 locks the handle assembly 20, the intelligent cabinet lock 100 is in a locked state. When the handle assembly 20 is located at the popped-out position and / or the electronic locking assembly 40 releases the handle assembly 20, the intelligent cabinet lock 100 is in an unlocked state. The elastic limiting member 50 is arranged in the lock body 10.

[0062] The lock body 10 is a component for being assembled on a cabinet door and providing mounting space for other structural members. Exemplarily, the lock body 10 can be a shell-shaped structural member.

[0063] In some embodiments, please refer to Figure 1 , the lock body 10 comprises a shell 11 and a first end cover 12. One end of the shell 11 is provided with an opening, and the first end cover 12 is detachably arranged in the shell 11 to close the opening, thereby providing a stable working space for the electronic locking assembly 40.

[0064] The handle assembly 20 is an assembly for driving the structural member (such as a steel bolt 70, a heaven-and-earth rod, etc.) for locking the cabinet to rotate to unlock the cabinet door.

[0065] The handle assembly 20 is movably connected to the lock body 10, which can be understood as the connection of the handle assembly 20 to the lock body 10 which can rotate around multiple axes. Exemplarily, the handle assembly 20 can be connected to the lock body 10 through a universal joint or a structure similar to the universal joint.

[0066] Exemplarily, please refer to Figure 1 , the handle assembly 20 can rotate around a first axis P1 and a second axis P2, wherein the first axis P1 is perpendicular to the second axis P2. The handle assembly 20 rotates around the first axis P1 to drive the structural member for locking the cabinet to rotate to unlock the cabinet door.

[0067] The stowed position and the ejected position are two positions of the handle assembly 20 within its range of motion.

[0068] The first elastic member 30 is a structural member for providing an elastic force to the handle assembly 20 to drive the handle assembly 20 to rotate from the stowed position to the ejected position. Exemplarily, the first elastic member 30 can be a rubber block or a spring.

[0069] In some embodiments, the first elastic member 30 is a torsion spring, the axis of the torsion spring is collinear with the second axis P2, specifically, when the handle assembly 20 is moved to the stowed position under the action of an external force, the first elastic member 30 is compressed; after the electronic locking assembly 40 releases the handle assembly 20, the first elastic member 30 elastically recovers and provides an elastic force to the handle assembly 20 to drive the handle assembly 20 to move to the ejected position.

[0070] The electronic locking assembly 40 is a structural assembly that can release the handle assembly 20 when the handle assembly 20 is in the stowed position, and lock the handle assembly 20 on the lock body 10.

[0071] Exemplarily, the electronic locking assembly 40 can lock the handle assembly 20 on the lock body 10 by providing an abutting force or a frictional force to the handle assembly 20, so as to limit the movement of the handle assembly 20, and further limit the operator from unlocking the cabinet door by rotating the handle assembly 20.

[0072] In some embodiments, the lock body 10 is recessed on one side of the handle assembly 20 to form a first mounting slot 10B adapted to the handle assembly 20, and the handle assembly 20 is located in the first mounting slot 10B when the handle assembly 20 is in the stowed position, and the first mounting slot 10B can limit the rotation of the handle assembly 20 around the first axis P1. The electronic locking assembly 40 can lock the handle assembly 20 in the stowed position by providing an abutting force or a frictional force to the handle assembly 20, so as to limit the movement of the handle assembly 20 under the action of the elastic force of the first elastic member 30 and eject the handle assembly 20 from the first mounting slot 10B. Thus, the operator cannot rotate the handle assembly 20 around the first axis P1 to unlock the cabinet, and thus the intelligent cabinet lock 100 is in a locked state. When the electronic locking assembly 40 no longer provides an abutting force or a frictional force to the handle assembly 20 to release the handle assembly 20, the handle assembly 20 moves to the ejected position under the action of the elastic force of the first elastic member 30 and ejects from the first mounting slot 10B. Thus, the operator can rotate the handle assembly 20 around the first axis P1 to unlock the cabinet, and thus the intelligent cabinet lock 100 is in an unlocked state.

[0073] The elastic limiting member 50 is a structural member that can elastically deform, as the name implies. Exemplarily, the elastic limiting member 50 can be a rubber block, a spring leaf, etc., which can provide a certain elastic force to the mechanism member to which an external force is applied when elastically deformed.

[0074] Specifically, during the process that the first elastic member 30 drives the handle assembly 20 to rotate from the stowed position to the popped-out position, the elastic limiting member 50 abuts against the handle assembly 20 and is elastically deformed to balance the elastic force provided by the first elastic member 30 to the handle assembly 20, so that the handle assembly 20 is kept in the intermediate position between the stowed position and the popped-out position. After the operator holds the handle assembly 20 by hand and applies an external force to the handle assembly 20, the elastic limiting member 50 is further elastically deformed and finally disengaged from the handle assembly 20, and the handle assembly 20 rotates to the popped-out position under the action of the elastic force of the first elastic member 30.

[0075] In the embodiment, during the process that the first elastic member 30 drives the handle assembly 20 to rotate from the stowed position to the popped-out position, the handle assembly 20 abuts against the elastic limiting member 50 and is kept in the intermediate position between the stowed position and the popped-out position. Specifically, when the operator brings the unlocking module (such as a computer key, a mobile phone, etc.) close to the intelligent cabinet lock 100 to make the electronic locking assembly 40 release the handle assembly 20, the elastic limiting member 50 can limit the handle assembly 20 in the intermediate position. After the operator stows the unlocking module, the operator can hold the handle assembly 20 by hand and apply an external force to the handle assembly 20 to drive the elastic limiting member 50 to elastically deform and drive the handle assembly 20 to continue to rotate to the popped-out position, thereby reducing the risk of the handle assembly 20 colliding with the operator's hand to cause the operator to be injured or the unlocking module to be damaged relative to the case that the first elastic member 30 drives the handle assembly 20 to rotate from the stowed position to the popped-out position without stopping.

[0076] According to some embodiments of the present application, please refer to Figure 1 , and please refer to Figures 2-5 , Figure 5 for Figure 3 the enlarged view of D in FIG. 1. The handle assembly 20 has a first end 20A and a second end 20B oppositely arranged, the first end 20A is movably connected to the lock body 10; the lock body 10 has a receiving groove 10A; when the handle assembly 20 is in the stowed position, the second end 20B is located in the receiving groove 10A; when the handle assembly 20 is in the popped-out position, the second end 20B is located outside the receiving groove 10A; the elastic limiting member 50 is arranged on the groove wall of the receiving groove 10A.

[0077] The first end 20A and the second end 20B are two ends of the handle assembly 20 oppositely arranged in the extension direction thereof. Exemplarily, the first end 20A is movably connected to the lock body 10, and the second end 20B is a free end.

[0078] It can be understood that, when the handle assembly 20 is in the stowed position, the second end 20B is located in the receiving groove 10A, the electronic locking assembly 40 located in the lock body 10 can abut against the second end 20B through the groove wall of the receiving groove 10A to provide an abutting force or a friction force to the handle assembly 20, thereby locking the handle assembly 20 in the lock body 10.

[0079] In some embodiments, referring to Figures 2-4 , the first elastic member 30 is arranged at the first end 20A, and the elastic limiting member 50 is arranged in the receiving groove 10A and abuts against the outer periphery of the second end 20B. It can be understood that, when the handle assembly 20 is in the stowed position, the second end 20B is located in the receiving groove 10A, the electronic locking assembly 40 located in the lock body 10 can abut against the second end 20B through the groove wall of the receiving groove 10A to provide an abutting force or a friction force to the handle assembly 20, thereby locking the handle assembly 20 in the lock body 10.

[0080] In some embodiments, referring to Figure 3 and Figure 5 , the receiving groove 10A has a first wall 10C away from the first end 20A, and the elastic limiting member 50 is arranged on the inner surface of the first wall 10C.

[0081] In the present embodiment, the elastic limiting member 50 is arranged on the groove wall of the receiving groove 10A, so that no additional connecting structure needs to be arranged on the lock body 10, thereby reducing the volume of the lock body 10, and further reducing the volume of the intelligent cabinet lock 100 having the lock body 10.

[0082] According to some embodiments of the present application, referring to Figure 3 , and referring to Figure 5 and Figure 6 , Figure 6 the structure explosion diagram of the handle assembly 20 provided by some embodiments of the present application.

The locking bolt 42 is no longer clamped on the locking member 22, and the handle assembly 20 is flipped out of the first mounting groove 10B relative to the lock body 10 under the action of the first elastic member 30, and in the process that the first elastic member 30 drives the handle assembly 20 to rotate from the stowed position to the popped-out position, the handle assembly 20 abuts against the elastic limiting member 50 and remains at the intermediate position between the stowed position and the popped-out position. After the operator stows the unlocking module, the operator can hold the handle assembly 20 by hand and apply an external force to the handle assembly 20 to drive the elastic limiting member 50 to elastically deform and drive the handle assembly 20 to continue to rotate to the popped-out position, thereby making the intelligent cabinet lock 100 in the unlocked state, at this time, rotating the handle assembly 20 can drive the rotating shaft 24 to rotate, thereby driving the steel bolt 70 to rotate by a certain angle, and completing the normal unlocking operation.

[0130] When the locking member 22 is ejected from the accommodating groove 10A without using the unlocking module, the magnetic member 63 on the handle body 21 is away from the sensing range of the Hall element, and the Hall element cannot detect the magnetic member 63. At this time, the control circuit board 60 judges that the locking member 22 has been completely ejected from the lock body 10, and controls the driving member 431 to rotate, so that the lock tongue 42 is switched from the unlocking position to the locking position. When the other of the two micro switches 62 is in abutment with the abutment portion, the control circuit board 60 controls the driving member 431 to stop rotating, and the lock tongue 42 is kept in the locking position. Specifically, when the operator presses the handle assembly 20 into the first mounting groove 10B, the handle assembly 20 can be held by hand and an external force is applied to the handle assembly 20 to drive the elastic limiting member 50 to elastically deform and drive the handle assembly 20 to continue to rotate to the stowed position. Subsequently, the side wall of the locking member 22 is in abutment with the guide surface 423 of the lock tongue 42, thereby pushing the lock tongue 42 to move into the lock body 10 and compressing the second elastic member 436. After the handle assembly 20 is located in the stowed position, the second elastic member 436 elastically recovers to drive the lock tongue 42 to move to the locking position, so that the lock tongue 42 is in abutment with the locking member 22, thereby locking the handle assembly 20 in the lock body 10, so that the intelligent cabinet lock 100 is in the locking state.

[0131] When the locking member 22 is ejected from the accommodating groove 10A without using the unlocking module, the magnetic member 63 on the handle body 21 is away from the sensing range of the Hall element, and the Hall element cannot detect the magnetic member 63. At this time, the control circuit board 60 judges that the locking member 22 has been completely ejected from the lock body 10, and controls the driving member 431 to rotate, so that the lock tongue 42 is switched from the unlocking position to the locking position.

Subsequently, the side wall of the locking member 22 is in abutment with the guide surface 423 of the lock tongue 42, thereby pushing the lock tongue 42 to move into the lock body 10 and compressing the second elastic member 436. After the handle assembly 20 is located in the stowed position, the second elastic member 436 elastically recovers to drive the lock tongue 42 to move to the locking position, so that the lock tongue 42 is in abutment with the locking member 22, thereby locking the handle assembly 20 in the lock body 10, so that the intelligent cabinet lock 100 is in the locking state.

[0132] When the locking member 22 is ejected from the accommodating groove 10A without using the unlocking module, the magnetic member 63 on the handle body 21 is away from the sensing range of the Hall element, and the Hall element cannot detect the magnetic member 63. At this time, the control circuit board 60 judges that the locking member 22 has been completely ejected from the lock body 10, and controls the driving member 431 to rotate, so that the lock tongue 42 is switched from the unlocking position to the locking position.
