[0046] Please also read Figures 1 to 4 The utility model provides an intelligent cabinet lock, which includes a lock body 100, a handle 200, a mechanical unlocking module 300 and an electrical unlocking module 400. The handle 200 is movably mounted on the lock body 100, the mechanical unlocking module 300 is mounted on the handle 200, and the electrical unlocking module 400 is mounted on the lock body 100.

[0047] The lock body 100 is provided with a receiving groove 110 and a limit block 120 located in the receiving groove 110. The lock body 100 can be made of many kinds of materials. The lock body 100 can be made of metal material, the lock body 100 can also be made of harder plastic, or the lock body 100 can also be made of other materials, which are not specifically limited here. The limit block 120 can be made of many kinds of materials. The limit block 120 can be made of metal material, the limit block 120 can also be made of harder plastic, or the limit block 120 can also be made of other materials, which are not specifically limited here. The limit block 120 can be integrally formed with the lock body 100, or the limit block 120 can be installed on the lock body 100, which are not specifically limited here.

[0048] The handle 200 is movably mounted on the lock body 100. The handle 200 can be made of many materials. The handle 200 can be made of metal materials, hard plastics, or other materials, which are not specifically limited here. There are many ways to movably mount the handle 200 on the lock body 100. The handle 200 can be movably mounted on the lock body 100 by flipping, or by sliding, which are not specifically limited here.

[0049] The mechanical unlocking module 300 is installed on the handle 200 and has a matching state and an emergency locking state. The mechanical unlocking module 300 is used to cooperate with a mechanical key to switch between the matching state and the emergency locking state. There are many ways to install the mechanical unlocking module 300 on the handle 200. The mechanical unlocking module 300 can be installed on the handle 200 by screw connection, the mechanical unlocking module 300 can also be installed on the handle 200 by buckling, and the mechanical unlocking module 300 can also be installed on the handle 200 by other ways, which are not specifically limited here.

[0050] The electrical unlocking module 400 is installed on the lock body 100 and has a locked state and an unlocked state. The electrical unlocking module 400 is controlled by the control background to switch between the locked state and the unlocked state. There are many ways to install the electrical unlocking module 400 on the lock body 100. The electrical unlocking module 400 can be installed on the lock body 100 by screw connection. The electrical unlocking module 400 can also be installed on the lock body 100 by snap connection. The electrical unlocking module 400 can also be installed on the lock body 100 by other ways, which are not specifically limited here.

[0051] When the mechanical unlocking module 300 is in the matched state, the electrical unlocking module 400 switches between the locked state and the unlocked state, so that the mechanical unlocking module 300 cooperates with the mechanical unlocking module 300 to limit the handle 200 or release the limit of the handle 200. It can be understood that when the mechanical unlocking module 300 is in the matched state, the electrical unlocking module 400 limits the handle 200 by limiting the mechanical unlocking module 300.

[0052] When the mechanical unlocking and locking module 300 is in the emergency locking state, the mechanical unlocking and locking module 300 cooperates with the limit block 120 to limit the handle 200. It can be understood that when the mechanical unlocking and locking module 300 is in the emergency locking state, the mechanical unlocking and locking module 300 limits the mechanical unlocking and locking module 300, thereby limiting the handle 200. When the mechanical unlocking and locking module 300 is in the emergency unlocking state, the mechanical unlocking and locking module 300 releases the limit on the handle 200.

[0053] During normal use, the mechanical unlocking module 300 is in a mating state. When the smart cabinet needs to be unlocked, the electrical unlocking module 400 is first controlled to switch from the locked state to the unlocked state, and then the handle 200 can be operated to move; when the smart cabinet needs to be locked, the handle 200 is first moved to the specified position, and then the electrical unlocking module 400 is controlled to switch from the unlocked position to the locked position.

[0054] When the electrical unlocking module 400 in the locked state fails, the handle 200 can be released from the limit by switching the mechanical unlocking module 300 from the matching state to the emergency unlocking state through a mechanical key.

[0055] When the electrical unlocking module 400 in the unlocked state fails, first move the handle 200 to the rotation position, and then use the mechanical key to switch the mechanical unlocking module 300 from the cooperation state to the emergency locking state, so that the handle 200 can be limited by the cooperation of the mechanical unlocking module 300 and the limit block 120.

[0056] The technical solution of the utility model realizes the emergency locking function by using a mechanical unlocking and locking module 300 to cooperate with a limit block 120 to limit the handle 200. The intelligent cabinet lock includes a lock body 100, a handle 200, a mechanical unlocking and locking module 300 and an electrical unlocking and locking module 400. The lock body 100 is provided with a limit block 120; the handle 200 is movably installed on the lock body 100; the mechanical unlocking and locking module 300 is installed on the handle 200 and has a matching state and an emergency locking state; the electrical unlocking and locking module 400 is provided with a mechanical unlocking and locking module 300 and an electrical unlocking and locking module 400. The pneumatic unlocking and locking module 400 is installed on the lock body 100 and has a locked state and an unlocked state; when the mechanical unlocking and locking module 300 is in the matching state, the electric unlocking and locking module 400 switches between the locked state and the unlocked state to cooperate with the mechanical unlocking and locking module 300 to limit or release the limit of the handle 200; when the mechanical unlocking and locking module 300 is in the emergency locking state, the mechanical unlocking and locking module 300 cooperates with the limit block 120 to limit the handle 200. In this way, when the electric unlocking and locking module 400 in the unlocking state fails, the mechanical unlocking and locking module 300 can be switched to the emergency locking state to cooperate with the limit block 120 to limit the handle 200, thereby avoiding the very serious consequences caused by the failure of the electric unlocking and locking module 400 to cause the intelligent cabinet lock to fail to lock due to the loss of limit of the handle, thereby improving the safety of the intelligent cabinet lock. When the electrical unlocking module 400 in the locked state fails, the mechanical unlocking module 300 can be switched to the emergency unlocking state by the mechanical key to unlock the intelligent cabinet lock. When the handle 200 closes the accommodating groove 110, the mechanical unlocking module 300 is placed in the accommodating groove 110, thereby protecting the mechanical unlocking module 300 and preventing the mechanical unlocking module 300 from being affected by the external environment.

[0057] Please also read Figures 1 to 4 In some embodiments of the utility model, the lock body 100 is further provided with an installation cavity 130 and an avoidance hole 140 connecting the installation cavity 130 and the accommodating groove 110, the limit block 120 is protruded from the groove wall of the accommodating groove 110, and the limit block 120 and the avoidance hole 140 are arranged at a circumferential interval in the accommodating groove 110; the electrical unlocking module 400 has a driving component 410 and a locking block 420, the driving component 410 is installed in the installation cavity 130, and the locking block 420 is transmission-connected with the driving component 410 so that the locking block 420 has a locking position extending from the avoidance hole 140 into the accommodating groove 110 and an unlocking position retracted into the installation cavity 130, and when the locking block 420 is in the locking position, the locking block 420 cooperates with the mechanical unlocking module 300 to limit the handle 200.

[0058] With such arrangement, the installation cavity 130 can protect the drive component 410, thereby preventing the drive component 410 from being affected by the external environment. At the same time, the electrical unlocking module 400 can be switched between the locked state and the unlocked state by controlling the locking block 420 to switch between the locked position and the unlocked position, thereby simplifying the structure of the electrical unlocking component 400.

[0059] Furthermore, the mechanical unlocking module 300 includes a lock core 310 and a locking assembly 320, the lock core 310 is installed on the handle 200, and the locking assembly 320 is located on the side of the locking block 420 away from the handle 200, and the locking assembly 320 is transmission-connected to the lock core 310 so that the locking assembly 320 has a mating position and an emergency locking position; when the locking assembly 320 is located at the mating position, the driving assembly 410 controls the locking block 420 to switch between the locking position and the unlocking position, so as to cooperate with the locking assembly 320 to limit the handle 200 or release the limit on the handle 200; when the locking assembly 320 is located at the emergency locking position, the locking assembly 320 cooperates with the limit block 120 to limit the handle 200.

[0060] In this way, by setting the part of the locking block 420 that extends into the receiving groove 110 on the movable path of the locking component 320, it can limit the mechanical unlocking module 300 and then limit the handle 200. In this way, the driving component 410 can be used to control the locking block 420 to extend into or out of the receiving groove 110 to limit or release the limit on the handle 200.

[0061] There are many types of the lock core 310, the lock core 310 can be a plum blossom pin type, the lock core 310 can also be an arc blade type, which is not specifically limited here. There are many types of the drive assembly 410, the drive assembly 410 can be an air pump, the drive assembly 410 can also be a servo motor, and the drive assembly 410 can also be a hydraulic press, which is not specifically limited here.

[0062] It can be understood that when the electrical unlocking module 400 is in a locked state, the locking block 420 is located in a locked position; when the electrical unlocking module 400 is in an unlocked state, the locking block 420 is located in an unlocked position; when the mechanical unlocking module 300 is in a mating state, the locking assembly 320 is located in a mating position; when the mechanical unlocking module 300 is in an emergency locking state, the locking assembly 320 is located in an emergency locking position.

[0063] During normal use, the locking component 320 is located in the mating position. When the smart cabinet needs to be unlocked, the locking block 420 is first controlled by the driving component 410 to switch from the locked position to the unlocked position, and then the handle 200 can be operated to move; when the smart cabinet needs to be locked, the handle 200 is first moved to the specified position, and then the locking block 420 is controlled by the driving component 410 to switch from the unlocked position to the locked position.

[0064] When the electrical unlocking module 400 fails in the unlocking state, the handle 200 is first moved to the rotating position, and then the locking assembly 320 is driven to switch from the matching position to the emergency locking position by the cooperation of the mechanical key and the lock cylinder 310, so that the handle 200 can be limited by the cooperation of the locking assembly 320 and the limit block 120.

[0065] Considering that when the handle 200 closes the receiving slot 110, the locking block 420 needs to be operated to the unlocking position first, and then the locking block 420 needs to be operated to the locking position after the handle 200 closes the receiving slot 110, which makes the operation of the smart cabinet lock cumbersome. In view of this, please refer to Figures 1 to 5 The locking assembly 320 includes a fixed seat 321, a locking piece 322 and an elastic piece 323. The fixed seat 321 is recessed with a movable groove 321a in the radial direction of the lock core 310. The fixed seat 321 is transmission-connected to the lock core 310. The locking piece 322 is movably installed in the movable groove 321a. The locking piece 322 partially extends out of the notch of the movable groove 321a. One end of the elastic piece 323 is connected to the locking piece 322, and the other end of the elastic piece 323 is connected to the bottom of the movable groove 321a. The elastic piece 323 is used to drive the locking piece 322 to extend out of the notch of the movable groove 321a.

[0066] With such arrangement, when the locking block 420 is in the locking position, the handle 200 can be directly operated to close the receiving groove 110. When the locking member 322 contacts the locking block 420, the locking member 322 is squeezed by the locking block 420, thereby compressing the elastic member 323, thereby avoiding interference between the locking member 322 and the locking block 420, resulting in the handle 200 being unable to close the receiving groove 110 when the locking block 420 is in the locking position. At the same time, after the handle 200 closes the receiving groove 110, the locking member 322 will be subject to the elastic force of the elastic member 323, thereby extending out of the notch of the movable groove 321a, and then cooperating with the locking block 420 to limit the handle 200.

[0067] Similarly, when the locking assembly 320 is switched to the emergency locking state, the handle 200 can also be directly operated to close the receiving groove 110. When the locking member 322 contacts the limit block 120, the locking member 322 is squeezed by the limit block 120, thereby compressing the elastic member 323, thereby avoiding interference between the locking member 322 and the limit block 120, resulting in the handle 200 being unable to close the receiving groove 110 when the locking block 420 is in the locked position. At the same time, after the handle 200 closes the receiving groove 110, the locking member 322 will be subject to the elastic force of the elastic member 323, thereby extending out of the notch of the movable groove 321a, and then cooperating with the limit block 120 to limit the handle 200.

[0068] Please also read Figures 1 to 6 In some embodiments of the utility model, the handle 200 is provided with two limiting protrusions 210 on one side facing the accommodating groove 110, and the two limiting protrusions 210 extend along the circumference of the lock core 310 respectively, and form two limiting channels 220 at intervals in the circumference of the lock core 310; the locking member 322 is provided with a mating protrusion 322a convexly facing the direction of the handle; when the mating protrusion 322a is located in one limiting channel 220, the locking assembly 320 can switch between the mating position and the emergency unlocking position; when the mating protrusion 322a is located in the other limiting channel 220, the locking assembly 320 is located in the emergency locking position.

[0069] In this configuration, the locking assembly is limited by the cooperation between the limiting protrusion 210 and the matching protrusion 322a, thereby preventing the handle 200 from being unable to open the accommodating groove 110 when the lock core 310 drives the locking assembly 320 to directly switch from the matching position to the emergency locking position, thereby improving the practicality of the smart cabinet lock.

[0070] When the locking component 320 needs to be switched to the emergency locking position, the locking member 322 is first pushed to compress the elastic member 323 so that the mating protrusion 322a leaves the limiting channel 220, and then the lock cylinder 310 is rotated by a mechanical key to drive the locking component 322 to switch to the emergency locking position, and then the locking member 310 is released. The locking member 322 is driven by the elastic member 323 so that the mating protrusion 322a enters another limiting channel 220.

[0071] Specifically, see Figure 5 The locking member 322 is provided with a guide arc surface 322b that cooperates with the locking block 420 or the limiting block 120 on the side away from the handle 200. With such a configuration, when the handle 200 closes the receiving groove 110, the friction between the locking member 322 and the locking block 420 or the limiting block 120 can be reduced, thereby improving the service life of the locking member 322, the locking block 420 and the limiting block 120.

[0072] Please also refer to Figures 1 to 5The end of the limit block 120 close to the mechanical unlocking module 300 is provided with a guide inclined surface 121 matched with the guide arc surface 322b, and the guide inclined surface 121 is gradually inclined toward the handle 200 in the direction away from the mechanical unlocking module 300. With such a configuration, when the handle 200 closes the receiving groove 110, the locking member 322 and the limit block 120 can be matched more smoothly, so that it is convenient for the staff to operate the intelligent cabinet lock, and at the same time, the friction between the locking member 322 and the limit block 120 is reduced, thereby improving the service life of the locking member 322 and the limit block 120.

[0073] The lock core 310 can be fixedly mounted on the handle 200, or can be detachably mounted on the handle 200. Preferably, the lock core 310 can be detachably mounted on the handle 200, so that it is convenient to maintain or replace the lock core 310 and the locking assembly 320. Specifically, a lock slot 230 is recessed on the side of the handle 200 away from the lock body 100, and a mounting hole 240 is provided through the bottom of the lock slot 230, and the lock core 310 is located in the lock slot 230; the mechanical unlocking and locking module 300 also includes a connecting member 330, which passes through the locking assembly 320 and the mounting hole 240 in sequence and is connected to the lock core 310, so that the locking assembly 320 is fastened to the lock core 310, and the mechanical unlocking and locking module 300 is fastened to the lock slot 230 at the same time.

[0074] In this way, the lock core 310 and the locking assembly 320 are connected to each other through the connecting piece 330, so that the lock core 310 and the locking assembly 320 can be replaced and repaired by simply removing the connecting piece 330. At the same time, it is convenient to replace the lock core 310 with a different function, and the mechanical unlocking module 300 is fastened to the lock slot 230 through the connecting piece 330, thereby reducing the structural setting of the mechanical unlocking module 300 installed in the lock slot 230, thereby optimizing the structure of the smart cabinet lock.

[0075] See also Figure 1 In some embodiments of the utility model, the smart cabinet lock further includes a detection component (not shown), which is installed on the handle 200 and / or the lock body 100, and is electrically connected to the control background. The detection component is used to detect the position of the handle 200 and feed it back to the control background. In this way, the detection component detects the position of the handle 200, so that the control background can determine whether the smart cabinet lock is locked by the position of the handle 200, thereby improving the security of the smart cabinet lock.
