The clutch pin 300 is movably installed in the connecting slot 220, and the driving module 400 is drivingly connected to the clutch pin 300.

[0048] The unlocking shaft 100 may be made of a variety of materials. The unlocking shaft 100 may be made of a metal material, a harder plastic, or other materials, which are not specifically limited here.

[0049] The handle module 200 is provided with a driving unit on the back of the handle module 200, and the driving unit is used for the staff to grasp so that the staff can drive the handle module 200 to rotate. The handle module 200 can be made of many materials, such as metal, harder plastic, or other materials, which are not specifically limited here.

[0050] The clutch pin 300 has a locked position and an unlocked position; when the clutch pin 300 is in the locked position, the clutch pin 300 is completely located in the connecting groove 220, so that the handle module 200 can rotate relative to the unlocking shaft 100, and the unlocking shaft 100 is stationary; when the clutch pin 300 is in the unlocking position, one end of the clutch pin 300 is located in the connecting groove 220, and the other end of the clutch pin 300 is located in the connecting channel 120, so that the handle module 200 and the unlocking shaft 100 rotate together through the transmission connection of the clutch pin 300.

[0051] When receiving the unlocking command, the driving module 400 drives the clutch pin 300 to switch between the locked position and the unlocked position. There are many ways for the driving module 400 to drive the clutch pin 300 to move. The driving module 400 can drive the clutch pin 300 to move by motor transmission, the driving module 400 can also drive the clutch pin 300 to move by hydraulic means, or the driving module 400 can drive the clutch pin 300 to move by an air pump, which is not specifically limited here. There are many installation positions for the driving module 400. The driving module 400 can be installed in the handle module 200, or the driving module 400 can be installed outside the handle module 200 and the unlocking shaft 100, which is not specifically limited here.

[0052] When the smart cabinet door lock is unlocked, an unlocking command is sent to the driving module 400, and the driving module 400 drives the clutch pin 300 to switch from the locked position to the unlocked position. At this time, the two ends of the clutch pin 300 are respectively located in the connecting channel 120 and the connecting groove 220, so that the handle module 200 and the unlocking shaft 100 are connected through the clutch pin 300, and then when the handle module 200 is rotated, the unlocking shaft 100 will rotate to unlock.

[0053] When the smart cabinet door lock is locked, a locking command is sent to the driving module 400, and the driving module 400 drives the clutch pin 300 to switch from the unlocking position to the locking position. At this time, the clutch pin 300 is completely located in the connecting groove 220, and the handle module 200 and the unlocking shaft 100 can rotate relative to each other, so that the handle module 200 and the unlocking shaft 100 can rotate relative to each other, thereby realizing the idling of the handle module 200.

[0054] The technical solution of the utility model realizes that when the intelligent cabinet door lock is locked, the handle module 200 rotates idly by using a clutch pin 300, an unlocking shaft 100 and a handle module 200. The unlocking shaft 100 is provided with a plug-in slot 110 on its axial surface, and a connecting channel 120 is provided on the peripheral wall of the plug-in slot 110. The handle module 200 is provided with a matching convex portion 210 on its surface facing the unlocking shaft 100, and the matching convex portion 210 is matched with the plug-in slot 110 in a clearance, and a connecting groove 220 is provided on the peripheral wall of the matching convex portion 210. The clutch pin 300 is movably installed in the connecting groove 220, so that the clutch pin 300 has a locked position and an unlocked position. When the clutch pin 300 is in the locked position, the clutch pin 300 is completely located in the connecting groove 220, so that the handle module 200 can rotate relative to the unlocking shaft 100, and the unlocking shaft 100 is stationary; when the clutch pin 300 is in the unlocking position, one end of the clutch pin 300 is located in the connecting groove 220, and the other end of the clutch pin 300 is located in the connecting channel 120, so that the handle module 200 and the unlocking shaft 100 are connected to each other through the transmission connection of the clutch pin 300 and rotate together; the driving module 400 is drivingly connected to the clutch pin 300, so that when the unlocking command is received, the clutch pin 300 is driven to switch between the locked position and the unlocked position. With such a configuration, when the smart door lock is locked, the clutch pin 300 can be completely located in the connection groove 220, so that the handle module 200 can rotate relative to the unlocking shaft 100, thereby achieving idling of the handle module 200, thereby preventing an unauthorized person from forcibly rotating the handle module 200 and causing the smart door lock to be damaged. When the smart door lock is unlocked, the drive module 400 drives the clutch pin 300 to switch from the locked position to the unlocked position, and the two ends of the clutch pin 300 are respectively located in the connection groove 220 and the connection channel 120, so that the rotation of the handle module 200 will drive the clutch pin 300 to rotate and drive the unlocking shaft 100 to rotate, and then the handle module 200 can unlock the unlocking shaft 100.

[0055] Please also read Figures 1 to 5 In some embodiments of the present invention, the connection channel 120 penetrates the outer peripheral wall of the unlocking shaft 100 to form an avoidance hole 130 on the outer peripheral wall of the unlocking shaft 100; the driving module 400 extends into the connection channel 120 from the avoidance hole 130. In this way, the driving module 400 can be arranged outside the unlocking shaft 100 and the handle module 200, thereby avoiding interference between the unlocking shaft and the handle module 200 and the driving module 400, and at the same time providing more installation space for the installation of the driving module 400, thereby facilitating the assembly of the intelligent cabinet door lock.

[0056] It should be noted that when the drive module 400 pushes the clutch pin 300 back to the locked position, the abutment surfaces of the drive module 400 and the clutch pin 300 are coplanar with the peripheral wall of the insertion slot 110, so that when the handle module 200 rotates, the drive module 400 will not interfere with the handle module 200.

[0057] Specifically, the driving module 400 includes a driving assembly 410, an arc-shaped unlocking block 430 and an elastic member 420. The arc-shaped unlocking block 430 is movably installed in the connecting channel. The end of the arc-shaped unlocking block 430 away from the clutch pin 300 extends along the circumferential direction of the unlocking shaft 100 and is arranged in an arc shape. The end of the arc-shaped unlocking block 430 close to the clutch pin 300 is arranged in a cylindrical shape and abuts against the clutch pin 300. The driving end of the driving assembly 410 abuts against the surface of the arc-shaped unlocking block 430 away from the clutch pin 300, and the driving end of the driving assembly 410 moves in a direction close to or away from the clutch pin 300. The elastic member 42 0 abuts against the bottom of the connecting groove, and the other end of the elastic member 420 abuts against the clutch pin 300; when the driving end of the driving assembly 410 moves toward the direction close to the clutch pin 300, the driving assembly 410 drives the arc-shaped unlocking block 430 to move toward the clutch pin 300, and the arc-shaped unlocking block 430 drives the clutch pin 300 to switch from the unlocking position to the locking position; when the driving assembly 410 moves in the direction away from the clutch pin 300, the elastic member 420 drives the clutch pin 300 to switch from the locking position to the unlocking position, and the clutch pin 300 drives the arc-shaped unlocking block 430 to move toward the direction close to the driving assembly 410.

[0058] In this configuration, the clutch pin 300 is pushed by the driving assembly 410 to return the clutch pin 300 to the locked position. When the driving assembly 410 moves in a direction away from the clutch pin 300, the elastic member 420 pushes the clutch pin 300 in the direction of the driving assembly 410, so that the clutch pin 300 abuts against the driving assembly 410, thereby making the clutch pin 300 and the driving assembly 410 move synchronously, and at the same time, it can ensure that the clutch pin 300 is stably located in the unlocking position, thereby ensuring the stability of the transmission between the unlocking shaft 100 and the handle module 200. The arc-shaped unlocking block 430 can increase the contact area with the driving assembly 410, thereby effectively avoiding the situation where the lock cannot be unlocked due to accidental deflection of the rotating shaft in the idling state, thereby improving the fault tolerance of the intelligent cabinet door lock.

[0059] There are many types of the elastic member 420 . The elastic member 420 may be a spring or an elastomer, which is not specifically limited here.

[0060] Please also read Figures 1 to 5In some embodiments of the utility model, the driving assembly 410 includes a driving member 411, a cam member 412 and a transmission pin 413. The driving member 411 is drivingly connected to the cam member 412, one end of the transmission pin 413 abuts against one end of the cam member 412, and the other end of the transmission pin 413 abuts against one end of the clutch pin 300, so that the cam member 412 rotates to drive the transmission pin 413 to move in a direction close to or away from the clutch pin 300.

[0061] In this arrangement, the cam member 412 is driven to rotate by the driving member 411, and the transmission pin 413 is driven to move by the abutment between the cam member 412 and the transmission pin 413, thereby fully utilizing the axial space of the smart cabinet door lock on the unlocking shaft 100, thereby making the internal parts of the smart cabinet door lock more compact, thereby reducing the size of the smart cabinet door lock and improving the applicability of the smart cabinet door lock.

[0062] Furthermore, the driving module 400 further includes a control mainboard 500, which is electrically connected to the driving member 411 and the control background. The surface of the control mainboard 500 facing the transmission pin 413 is provided with a locking photoelectric door 510 and an unlocking photoelectric door 520, and the surface of the transmission pin 413 facing the control mainboard 500 is convexly provided with a trigger part 413a; when the clutch pin 300 is in the locking position, the trigger part 413a extends into the locking photoelectric door 510; when the clutch pin 300 is in the unlocking position, the trigger part 413a extends into the unlocking photoelectric door 520. In this arrangement, the trigger part 413a cooperates with the unlocking photoelectric door 520 and the locking photoelectric door 510, so that the control background can obtain the unlocking state of the smart door lock in real time, thereby improving the safety of the smart door lock.

[0063] The controller can be a single chip microcomputer, a PWM control board, a microprocessor, or other devices. The controller is electrically connected to the driver 411 and the control background. The controller and the driver 411 can be electrically connected through wires. The controller and the driver 411 can also be connected by wireless connection methods such as WIFI and Bluetooth, which are not specifically limited here. The controller and the control background can be connected by wireless connection methods such as WIFI and Bluetooth, which are not specifically limited here.

[0064] Please also read Figures 1 to 5In some embodiments of the utility model, the smart cabinet door lock further includes a mechanical unlocking module 600, which is drivingly connected to the driving assembly 410, and is used to drive the driving assembly 410 to move in a direction close to or away from the clutch pin 300. In this way, when the driving assembly 410 cannot work, the mechanical unlocking module 600 can be used to drive the assembly 410 to move in a direction away from the clutch pin 300, so that the clutch pin 300 is affected by the elastic force of the elastic member 420 and switches from the locked position to the unlocked position, so that the staff can rotate the unlocking shaft 100 by rotating the handle module 200, so that the smart cabinet door lock has mechanical emergency unlocking, which improves the practicality of the smart cabinet door lock.

[0065] Specifically, the mechanical unlocking module 600 includes a first lock core 610, a first transmission plate 620 and a locking member 630. The first lock core 610 is drivingly connected to the first transmission plate 620. A transmission portion 621 is convexly provided on the surface of the first transmission plate 620 away from the first lock core 610. The transmission portion 621 is spaced apart from the rotation center axis of the first transmission plate 620. A transmission groove 631 and a matching groove 632 are concavely provided on the surface of the locking member 630 facing the first transmission plate 620. The two groove walls of the transmission groove 631 in the width direction of the locking member 630 are penetrated. The transmission groove 631 is plugged and matched with the transmission portion 621, so that the first transmission plate 620 rotates to drive the locking member 630 to move in a direction close to or away from the clutch pin 300. The driving assembly 410 is provided with a transmission convex portion 414 plugged and matched with the matching groove 632, so that the locking member 630 drives the driving assembly 410 to move in a direction close to or away from the clutch pin 300.

[0066] With such arrangement, the staff rotates the first lock core 610 with the key to drive the first transmission plate 620 to rotate, and the first transmission plate 620 drives the locking member 630 to move through the transmission part 621, and the locking member 630 drives the driving assembly 410 to move through the transmission protrusion 414, thereby making full use of the axial space of the smart cabinet door lock on the unlocking shaft 100, thereby making the internal structure of the smart cabinet door lock compact, thereby reducing the size of the smart cabinet door lock and improving the practicality of the smart cabinet door lock.

[0067] It should be noted that the drive assembly 410 includes a mounting bracket, a drive member 411, a cam member 412 and a transmission pin 413. The drive member 411 is mounted on the mounting bracket, and the drive member 411 is drivingly connected to the cam member 412. One end of the transmission pin 413 abuts against one end of the cam member 412, and the other end of the transmission pin 413 abuts against one end of the clutch pin 300, so that the cam member 412 rotates to drive the transmission pin 413 to move in a direction close to or away from the clutch pin 300. At this time, the mounting bracket is close to the clutch pin 300. A transmission protrusion 414 is provided at one end of the locking member 630. The movement of the locking member 630 will only drive the installation bracket, the driving member 411 and the cam member 412 to move, which will easily cause the transmission pin 413 to hinder the clutch pin 300 from switching to the unlocking position. In view of this, the mechanical unlocking module 600 also includes a spring, one end of which abuts against the outer peripheral wall of the unlocking shaft 100, and the other end of the spring abuts against the transmission pin 413. The spring is used to drive the transmission pin 413 to move in a direction away from the unlocking shaft 100.

[0068] In this arrangement, when the locking member 630 drives the mounting bracket, the driving member 411 and the cam member 412 to move, the spring will drive the transmission pin 413 to move in a direction away from the unlocking shaft 100, thereby ensuring that the transmission pin 413 and the clutch pin 300 move synchronously under the drive of the spring and the elastic member 420, thereby ensuring that the clutch pin 300 can be switched to the unlocking position.

[0069] In some embodiments of the utility model, a positioning protrusion 412a is provided on the surface of the driving component 410 facing the locking member 630, and a positioning groove 633 is recessed on the surface of the locking member facing the driving component 410. The positioning protrusion 412a is plugged into and matched with the positioning groove 633. In this way, the driving component 410 can be positioned by the positioning groove 633 and the positioning protrusion 412a, thereby ensuring that the driving component 410 can accurately drive the arc-shaped unlocking block 430 to move, thereby ensuring that the clutch pin 300 switches between the unlocking position and the locking position.

[0070] In some embodiments of the present invention, the mechanical unlocking module 600 further includes a second lock core 640 and a second transmission plate 650, the second lock core 640 and the second transmission plate 650 are in transmission connection, the second transmission plate 650 is provided with a limiting portion 651 on the surface facing the locking member 630, the limiting portion 651 is spaced apart from the rotation center axis of the second transmission plate 650, and the limiting portion 651 has a limiting position close to the clutch pin 300 and an unlocking position away from the clutch pin 300; the locking member 630 is provided with a limiting portion 651 on the surface facing the locking member 630, and the limiting portion 651 is spaced apart from the rotation center axis of the second transmission plate 650. A limiting groove 634 is concavely provided on the surface of the second transmission plate 650 facing the clutch pin 300, and the limiting groove 634 extends in a direction close to or away from the clutch pin 300, and is penetrated by two groove walls in the width direction of the locking member 630; the limiting portion 651 extends into the limiting groove 634, and when the limiting portion 651 is in the limiting position, the limiting portion 651 abuts against the groove wall of the limiting groove 634 close to the clutch pin 300, so that the limiting portion 651 limits the locking member 630 in the direction away from the clutch pin 300. When the limiting portion 651 is in the unlocking position, the limiting portion 651 releases the limit on the locking member 630.

[0071] In this way, the limiting portion 651 will cooperate with the groove wall of the limiting groove 634 to limit the locking member 630, so that it is necessary to first operate the second lock core 640 to unlock the limit of the locking member 630 in the direction away from the unlocking axis 100 before the first lock core 610 can be operated to drive the locking member 630 to move. This makes it necessary for the mechanical unlocking module 600 to use two keys to operate the first lock core 610 and the second lock core 640 respectively before the smart cabinet door lock can be unlocked, thereby improving the reliability of the smart cabinet door lock.

[0072] When the smart cabinet door lock is mechanically unlocked, the second lock core 640 is rotated by the key, thereby driving the second transmission plate 650 to rotate so that the limiting portion 651 moves to the side of the limiting groove 634 away from the unlocking shaft 100, and then the first lock core 610 is rotated by another key, thereby driving the first transmission plate 620 to rotate so that the transmission protrusion 414 drives the locking member 630 to move in the direction away from the unlocking shaft 100. At this time, the limiting portion 651 is located on the side of the limiting groove 634 close to the unlocking shaft 100, and the locking member 630 drives the driving assembly 410 to move in the direction away from the unlocking shaft 100. The clutch pin 300 moves from the locked position to the unlocked position under the drive of the elastic member 420, and the smart cabinet door lock is unlocked.

[0073] When the smart cabinet door lock is mechanically locked, the first lock core 610 is rotated by the key, thereby driving the first transmission plate 620 to rotate so that the transmission protrusion 414 drives the locking member 630 to move in the direction close to the unlocking shaft 100. At this time, the limiting portion 651 is located on the side of the limiting groove 634 away from the unlocking shaft 100, and the locking member 630 drives the driving assembly 410 to move in the direction close to the unlocking shaft 100, thereby driving the clutch pin 300 to switch from the unlocking position to the locking position, and then the second lock core 640 is rotated by another key, thereby driving the second transmission plate 650 to rotate so that the limiting portion 651 is located on the side of the limiting groove 634 close to the unlocking shaft 100, so that the limiting portion 651 cooperates with the wall of the limiting groove 634 to limit the locking member 630 in the direction away from the unlocking shaft 100.

[0074] Furthermore, the smart door lock further includes two wireless chips 700, which are respectively mounted on the surfaces of the first lock core 610 and the second lock core 640 away from the locking member 630, and the wireless chips 700 are used to send signals to the key. In this way, by setting two different wireless chips 700, the first lock core 610 and the second lock core 640 can only be operated by a designated electronic key, thereby improving the security of the smart door lock.
