When the two conductive contacts (1151,1152) are conductive, the power supply to the drive member 117 is also conductive; when the two conductive contacts (1151,1152) are open, the power to the actuator 117 is also open and the relay 115 functions as a switch.

Specifically, the two conductive contacts (1151,1152) of relay 115 are divided into a movable contact 1151 and a fixed contact 1152; the movable contact piece 1151 is made of a metal elastic material, has certain elasticity, is in a strip sheet shape, and has one end fixed to one side end of the main body of the relay 115 and the other end suspended upwards and positioned right behind the tail end of the lock rod 112; the fixed contact 1152, which is actually a metal contact, is disposed at the other side of the main body of the relay 115 and is located directly below the free end of the movable contact 1151. When the lock needs to be unlocked, the lock rod 112 retracts under the driving of the driving piece 117, so that the tail end of the lock rod 112 drives the free end of the movable contact 1151 to be contacted with the fixed contact 1152, the relay 115 is connected, the driving piece 117 is in a power-off state at the moment, the driving is stopped, and the lock rod 112 also stops moving backwards; on the contrary, when the lock is required, the lock lever 112 moves outward under the restoring force of the coil spring, so that the tail end of the lock lever 112 is disengaged from the driving of the free end of the movable contact 1151, the free end of the movable contact 1151 is disconnected from the fixed contact 1152, the relay 115 is disconnected, and the driving member 117 is in a conductive state.

Preferably, in an embodiment, as shown in fig. 4 and 5, an elastic member 116 is sleeved on the tail portion 1122 of the lock lever 112, and the elastic member 116 is in a compressed state between the lock lever 112 and the wall of the appliance cavity 102. Specifically, the elastic component 116 is a coil spring, one end of the coil spring 116 abuts against the blocking wall 119 of the electrical appliance cavity 102, the other end of the coil spring abuts against a step wall 1124 disposed on the middle section of the lock lever 112, and the blocking wall 119 of the electrical appliance cavity 102 is perpendicular to the axis of the lock lever 112. The spiral spring 116 abuts against and contacts the blocking wall 11 and the step wall 1124 respectively, so that the spiral spring 116 is normally in a pressed state, i.e., in an elastic recovery state, when the cabinet door is closed, the lock tongue 1123 of the lock rod 112 can be driven to extend out of the lock body 110 by the elastic restoring force of the spiral spring 116 without turning on the power supply in the direction of the driving piece 117, and the lock tongue 1123 is inserted into the lock hole 2102 of the lock catch 211, so that the electronic cabinet lock is locked.

Preferably, as shown in fig. 4, 5 and 10, the driving member 117 is a micro motor, and a cam 1171 is provided on a rotating shaft of the micro motor, and accordingly, a square recess 1121 is provided at a middle section of the lock lever 112, and the cam 1171 is disposed in the square recess 1121. The cam 1171 moves back and forth within the square notch 1121 with the rotation axis of the micro-motor 117; firstly, the lock rod 112 is driven to extend outwards, so that the bolt 1123 extends out of the lock body 110 and extends into the lock hole 2101 of the lock catch 221 to be in a locking state; secondly, the lock rod 112 is driven to retract, so that the bolt 1123 retracts into the lock body 110 and is separated from the lock hole 2101 of the lock catch 221, and the lock is unlocked. The length of the track of the cam 1171 that rotates once around the axis of the square recess 1121 is the same as the length of the bolt 1123 that extends out of the lock body 110, so that it is ensured that the bolt is fully retracted into the lock body when unlocking and can extend out of the lock body 110 and into the lock hole 2102 when closing.

Preferably, the circuit control unit 10 further includes an alarm prompt module 1184 controlled by the microprocessor 1180, and configured to send an alarm prompt when the sensing module 1181 is not matched with the external unlocking signal. For example, when the user uses the smart phone 300 to unlock the electronic cabinet lock of the storage cabinet in which other articles are stored, the microprocessor 1180 determines that the storage cabinet does not belong to the user, and outputs an alarm instruction, and the alarm module 1184 outputs an alarm prompt, such as a voice-operated prompt, a light-operated flash, a text prompt, to one or more of a display screen, a speaker, an LED lamp, and the like, which are electrically connected to the alarm module.

Preferably, the circuit control unit 10 further includes a display module 1185 controlled by the microprocessor 1180, and configured to display the use status information of the electronic cabinet lock. For example, after the storage cabinet is opened, the microprocessor 1180 outputs the deduction amount to a display screen electrically connected to the storage cabinet through the display module 1185, and the display screen displays information such as a corresponding deduction amount and a storage duration, or local weather state information provided by the cloud-end controller 200, such as temperature, humidity, and clear or cloudy weather.

Preferably, as shown in fig. 3, a data line interface 1105 electrically connected to the circuit board 118 is disposed on the lock body 110 for transmitting data, such as processing and repairing the circuit control unit 10, or charging a rechargeable battery in the lock body 110; or when the power supply in the lock body 110 is dead, the electronic cabinet lock is emergently started by an external standby power supply so as to unlock or close the lock. The data line interface 1105 may be any one of a miniUSB interface, a Type-C interface, a Lighting interface, and the like.

It should be understood that the above description is illustrative of the preferred embodiment of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
