[0035] The utility model provides an intelligent cabinet lock. Figure 1 The intelligent cabinet lock includes a lock body 1, a mechanical lock structure 2 and an electrical lock structure 3. The mechanical lock structure 2 includes a lock core 21 and a lock tongue 22, and the electrical lock structure 3 includes a lock sleeve 33, which is movably connected to the lock body 1. The lock core 21 is arranged in the lock sleeve 33. The lock core 21 can rotate relative to the lock sleeve 33 under the action of an external key. The lock tongue 22 is fixedly connected to the lock core 21, and the lock tongue 22 is also connected to the lock sleeve 33. The lock tongue 22 and the lock sleeve 33 can rotate synchronously or relatively, and the lock tongue 22 is used to connect with the linkage structure of the cabinet to realize the closing function of the cabinet.

[0036] The electric lock structure 3 also includes a main control board 31, a locking assembly 32 and a knob 34, all of which are connected to the lock body 1. The knob 34 is connected to the lock sleeve 33 and moves synchronously with the lock sleeve 33. The main control board 31 is electrically connected to the locking assembly 32. The main control board 31 is used to receive an unlocking command or a locking command sent by an external terminal device. The locking assembly 32 has a locked state for locking the lock sleeve 33 and an unlocked state for unlocking the lock sleeve 33. The main control board 31 also controls the locking assembly 32 to switch between the locked state and the unlocked state according to the unlocking command or the locking command.

[0037] With such arrangement, the smart cabinet lock can realize unlocking or locking through an external terminal device, and emergency unlocking or locking through a mechanical key through the electrical lock structure 3 and the mechanical lock structure 2, that is, the main control board 31, the locking assembly 32, the lock core 21, the lock sleeve 33 and the lock tongue 22. It has two different functions of electrical unlocking and mechanical unlocking, has good practicality and stability, has less potential safety hazards, good reliability and novelty, and a high degree of intelligence. In addition, the modular design of components makes the overall structure simple, compact, easy to use, and low in cost, which well meets the market demand for low-cost office locks.

[0038] The main control board 31 has a communication module, and the external terminal device can be a mobile phone, tablet computer, notebook, remote control, etc. The external terminal device establishes a communication connection with the communication module, and the communication module can be connected by wireless communication via Bluetooth, WIFI, infrared, etc. to receive unlocking instructions and locking instructions sent by the terminal.

[0039] The lock body 1 includes a panel 11 and a mounting seat 12, the mounting seat 12 is provided with a mounting groove 121, the panel 11 is fixedly connected to the mounting seat 12 and covers the notch of the mounting groove 121, and the lock cylinder 21, the lock sleeve 33, the lock tongue 22, the main control board 31 and the locking assembly 32 and other structures are installed in the mounting seat 12. The mounting seat 12 is used to be installed on a cabinet, so that the lock cylinder 21, the lock sleeve 33, the lock tongue 22, the main control board 31 and the locking assembly 32 and other structures are stably installed on the cabinet, and the panel 11 can be exposed to the external space, so that the user can perform operations such as waking up the system, mechanical unlocking or locking, etc.

[0040] The panel 11 may be provided with a button 111, which is arranged in alignment with the start key on the main control board 31. The button 111 allows a user to press the start key of the main control board 31 to wake up the system for electrical unlocking or locking operations.

[0041] There are many ways to fix the panel 11 to the mounting base 12, such as fixing with screws, fixing with snaps or bonding with glue, etc. As long as the panel 11 can be fixedly mounted on the mounting base 12, no specific limitation is made here.

[0042] Reference Figures 1 to 7 The locking assembly 32 includes a locking member 322 and an electrical stopper 323, wherein the locking member 322 and the electrical stopper 323 are both connected to the lock body 1. The locking member 322 is used to stop and cooperate with the lock sleeve 33. The electrical stopper 323 is electrically connected to the main control board 31, and the electrical stopper 323 is used to limit the movement of the locking member 322 when the power is off or to release the restriction on the locking member 322 when the power is on, so that the locking member 322 stops the movement of the lock sleeve 33 or releases the movement restriction on the lock sleeve 33.

[0043] The locking assembly 32 may further include a mounting shell 321, which is connected to the lock body 1, that is, the mounting shell 321 is mounted in the mounting groove 121 of the mounting seat 12. The mounting shell 321 is provided with a receiving cavity 3211 and an avoidance hole (not shown) communicating with the receiving cavity 3211, the locking member 322 and the electrical limit member 323 may both be arranged in the receiving cavity 3211, and the avoidance hole is arranged toward the lock sleeve 33 and allows the locking member 322 to pass through.

[0044] By configuring in this way, in the event of a power outage, the lock sleeve 33 is automatically locked by the locking assembly 32, so that the lock sleeve 33 is restricted from rotating relative to the lock body 1, so that the cabinet can remain in a closed state, thereby improving the safety of the smart cabinet lock after power outage and enhancing the safety of cabinet closure.

[0045] In addition, in the event of a power outage, the mechanical key is plugged into the lock core 21, and the restriction on the rotation of the lock core 21 relative to the lock sleeve 33 is released under the action of the mechanical key, so that the lock core 21 can drive the lock tongue 22 to rotate, thereby unlocking the cabinet and achieving emergency unlocking.

[0046] Continue to refer to Figures 1 to 7 The locking assembly 32 includes a mounting shell 321 connected to the lock body 1, and the locking member 322 includes a locking block 3221. The locking block 3221 is rotatably connected to the mounting shell 321 through a pin 4, that is, the locking block 3221 is arranged in the accommodating cavity 3211. The locking block 3221 has a locking portion 3222 and a resisting portion 3223. The outer peripheral wall of the lock sleeve 33 is provided with a locking groove 331. The locking portion 3222 passes through the avoidance hole and slides in contact with the outer peripheral wall of the lock sleeve 33 and is used to extend into or withdraw from the locking groove 331. The resisting portion 3223 resists or disengages from the electrical limiting member 323. In the locked state, the locking portion 3222 is restricted by the electrical limiting member 323 to maintain the state of extending into the locking groove 331, so as to restrict the lock sleeve 33 from moving relative to the locking portion 3222. In the unlocked state, the electrical limiting member 323 releases the restriction on the locking portion 3222 , so that the locking sleeve 33 can move relative to the locking portion 3222 .

[0047] The locking block 3221 is provided with a through hole 3224 , and the pin 4 passes through the through hole 3224 to confine the locking block 3221 in the accommodating cavity 3211 . The locking block 3221 can rotate around the axis of the pin 4 .

[0048] The electrical limiter 323 is a solenoid, and the electrical lock structure 3 further includes a battery 5, which is installed in the lock body 1. The main control board 31 and the solenoid are both electrically connected to the battery 5, and the main control board 31 controls the battery 5 to power or cut off the power to the solenoid. The iron core in the solenoid is arranged toward the locking block 3221, and the iron core in the solenoid can shrink when the solenoid is powered on, and the iron core in the solenoid can pop out when the solenoid is disconnected from the power supply.

[0049] When in the locked state, the locking portion 3222 extends into the locking groove 331, and the main control board 31 controls the battery 5 to stop supplying power to the solenoid, so that the solenoid is in an unpowered state. When the power is off, the iron core in the solenoid pops out and presses against the stopping portion 3223 of the locking block 3221, thereby limiting the rotation of the locking block 3221, thereby indirectly limiting the movement of the lock sleeve 33, thereby locking the lock sleeve 33.

[0050] When in the unlocked state, the main control board 31 controls the battery 5 to supply power to the solenoid, so that the iron core inside the solenoid can contract to release the restriction on the resisting portion 3223, that is, the locking block 3221 releases the constraint on the locking sleeve 33, so that the locking sleeve 33 can rotate relative to the locking block 3221, and during the rotation process, force the locking portion 3222 to disengage from the locking groove 331, thereby achieving unlocking.

[0051] Based on the above arrangement, under the restriction of the solenoid, the locking part 3222 of the locking block 3221 is used to block the rotation of the lock sleeve 33, so that the lock sleeve 33 is restricted from rotating, thereby locking the lock sleeve 33; or when the solenoid releases the restriction on the locking block 3221, the locking part 3222 releases the blocking of the lock sleeve 33, so that the lock sleeve 33 can rotate relative to the lock body 1 to unlock the lock sleeve 33. The transmission method is simple, the size is small, and it is easy to use, which greatly improves the reliability of locking or unlocking the smart cabinet lock, thereby enhancing the user experience.

[0052] In other embodiments, the electrical limiter 323 may also be an electrical component that has the function of limiting the blocking portion 3223 when the power is off and releasing the limit on the blocking portion 3223 when the power is on, which will not be described in detail herein.

[0053] Continue to refer to Figures 1 to 7 The locking assembly 32 also includes a reset member 324. The mounting shell 321 is provided with an assembly hole 3212. The assembly hole 3212 is communicated with the accommodating cavity 3211. The reset member 324 is movably arranged in the assembly hole 3212. One end of the reset member 324 abuts against the mounting shell 321, and the other end abuts against the locking block 3221. The reset member 324 is used to provide a restoring force when the locking block 3221 switches from an unlocked state to a locked state.

[0054] Through the reset member 324, in the process of switching from the unlocked state to the locked state, the locking block 3221 can quickly and smoothly lock the locking sleeve 33. At the same time, under the action of the reset member 324, the locking portion 3222 can stably extend into the locking groove 331 to improve the stopping performance of the locking sleeve 33, thereby improving the safety and reliability of the locked cabinet.

[0055] Among them, the reset member 324 can be sleeved on the outside of the pin 4, the reset member 324 can be a torsion spring, the reset member 324 can also be a torsion plate, and the reset member 324 can also be other structural members with a reset function, which are not listed here one by one.

[0056] The locking assembly 32 may further include a limiting screw 6, which is disposed at the edge of the opening of the assembly hole 3212 and is threadedly connected to the mounting shell 321. The limiting screw 6 is used to limit the reset member 324 in the assembly hole 3212 to effectively prevent the reset member 324 from being separated from the assembly hole 3212, and helps the reset member 324 to stably drive the locking block 3221 to reset, thereby improving the efficiency of the locking block 3221 locking the lock sleeve 33.

[0057] Continue to refer to Figures 1 to 7 The electric lock structure 3 also includes a hand sensor 7, which is installed on the side of the installation shell 321 facing the lock sleeve 33. The hand sensor 7 is in sliding contact with the outer wall of the lock sleeve 33. The outer wall of the lock sleeve 33 is provided with a hand feeling position 332. In the locked state, the hand sensor 7 is aligned with the hand feeling position 332.

[0058] In the locked state, the hand sensing member 7 is aligned with the hand feeling position 332 to remind the user that the lock is in place, thereby improving the user's experience. For example, the hand sensing member 7 may be a bump bead, and the hand feeling position 332 may be a groove. In the locked state, the bump bead falls into the groove and makes a knocking sound to remind the user that the lock sleeve 33 is locked in place.

[0059] In other embodiments, the hand sensing element 7 may also be a position sensor or a micro switch, and the hand sensing position 332 may be a trigger position. When the lock sleeve 33 is locked in place, the position sensor or the micro switch emits a response sound through a micro speaker to prompt the user that the lock sleeve 33 is locked in place.

[0060] Continue to refer to Figures 1 to 7 The lock body 1 is provided with an installation cavity (not shown) and an installation hole 112 communicating with the installation cavity. The panel 11 and the installation groove 121 of the installation seat 12 enclose the installation cavity. The installation hole 112 is formed on the panel 11. One end of the lock sleeve 33 is movably arranged in the installation cavity, and the other end passes through the installation hole 112 and extends out of the installation cavity. The knob 34 is sleeved on the outer peripheral wall of the end of the lock sleeve 33 located outside the installation cavity. The knob 34 is used to facilitate the user to drive the lock sleeve 33 to unlock or lock.

[0061] In the process of unlocking or locking, the unlocking or locking state of the lock sleeve 33 is judged only by the knob 34. With such a setting, the logic judgment process is simple and efficient, which simplifies the previous electrical logic scheme and greatly improves the reliability of electrical unlocking.

[0062] The main control board 31 has a position detection module 311, and one end of the lock sleeve 33 located in the installation cavity is provided with a sensing part 333, and the sensing part 333 is inductively matched with the position detection module 311. Such a configuration facilitates the detection of the unlocked state or the locked state of the lock sleeve 33, thereby improving the user's use effect and experience.

[0063] The sensing part 333 may be a magnet, and the position detection module 311 may be a micro switch, a photoelectric sensor, a reed switch, or other electrical devices with detection functions, which are not listed here one by one.

[0064] Continue to refer to Figures 1 to 7 The inner wall of the lock sleeve 33 is provided with a card slot 334, and the lock core 21 is provided with a locking part (not shown in the figure). The locking part is withdrawn from the card slot 334 under the action of the external key. When the external key is not inserted into the lock core 21, the locking part remains in the state of extending into the card slot 334. When the external key is inserted into the lock core 21, the locking part can withdraw from the card slot 334. This arrangement enables emergency unlocking of the cabinet in the event of a power outage, or unlocking the cabinet when the electrical unlocking fails or malfunctions in the locked state, thereby ensuring that the unlocking function will not fail, thereby greatly improving the performance of the intelligent cabinet lock.

[0065] The locking portion may be a blade or other structural member with a locking function, which will not be described in detail here.

[0066] The mechanical lock structure 2 also includes a connecting member 9, and the lock tongue 22 is provided with an arc hole 221, and the arc hole 221 is extended along the circumference of the lock tongue 22. One end of the connecting member 9 passes through the arc hole 221 and is fixedly connected to the lock sleeve 33. The connecting member 9 is used to connect the lock sleeve 33 and the lock tongue 22. The lock tongue 22 moves synchronously or relatively with the lock sleeve 33 under the action of the connecting member 9. In this way, it can be ensured that the lock tongue 22 can move with the lock sleeve 33 to achieve electrical unlocking, and can move relative to the lock sleeve 33 to achieve mechanical unlocking, and has both electrical unlocking and mechanical unlocking functions.

[0067] The connecting member 9 may be a connecting structure such as a connecting screw or a fixing pin.

[0068] The locking tongue 22 may include a rotor 222 and a rotating ear 223 . The rotor 222 and the rotating ear 223 are detachably connected. The rotor 222 is movably connected to the locking sleeve 33 . The arc-shaped hole 221 is formed in the rotor 222 .

[0069] Reference Figures 1 to 7 , the working principle of the intelligent cabinet lock is described as follows:

[0070] Unlocking principle: in the normal locked state, the button 111 on the panel 11 is pressed to wake up the Bluetooth system of the smart cabinet lock, the mobile phone terminal communicates with the communication module on the main control board 31, the mobile phone terminal sends an unlocking command, the communication module of the main control board 31 receives the unlocking command, the main control board 31 controls the battery 5 to energize the solenoid, the iron core in the solenoid contracts, so that the iron core in the solenoid releases the hard limit of the resisting part 3223, in this case, by rotating the knob 34, the lock sleeve 33 is driven to rotate, and during the rotation of the lock sleeve 33, the locking groove 331 moves the locking part 3222 to force the locking part 3222 to disengage from the locking groove 331, until the locking part 3222 completely disengages from the locking groove 331;

[0071] When the knob 34 is turned to the unlocking position, the position detection module 311 cannot detect the position of the sensing part 333, and the main control board 31 controls the battery 5 to stop supplying power to the solenoid, and then the system goes to sleep. At this time, the iron core in the solenoid is in a partially popped-out state, completing the unlocking operation.

[0072] Locking principle: In the unlocked state, the user twists the knob 34 and rotates the knob 34 to the locked position. The locking portion 3222 of the locking block 3221 pops out and extends into the locking groove 331 under the action of the reset member 324. Then the iron core in the solenoid continues to pop out, so that the iron core in the solenoid is in a completely popped out state, so that the iron core in the solenoid abuts against the resisting portion 3223 to limit the rotation of the locking block 3221, thereby realizing a self-resetting locking operation.

[0073] Emergency unlocking principle: when it is normally in the locked state, insert the mechanical key into the lock core 21, the blades of the lock core 21 are retracted, the lock core 21 and the lock sleeve 33 are in a clutch state, and the lock sleeve 33 is in a hard limit state under the restriction of the locking block 3221, so the lock sleeve 33 is also in the locked position and does not move. Rotating the lock core 21 can drive the rotor 222 and the rotating ear 223 to rotate alone, thereby driving the closing mechanism of the cabinet to rotate to achieve emergency unlocking.

[0074] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
