Example 1:

as shown in fig. 1 to 3, the intelligent cabinet lock comprises a lock body, a lock bolt 2 axially movably arranged in the lock body, a lock bolt spring 3 acting on the lock bolt 2, and an intelligent unlocking system for controlling the motion of the lock bolt 2. The spring 3 makes the working end of spring bolt 2 can stretch out the lock body to the elasticity of spring bolt 2, and intelligent unlocking system restricts the axial position of spring bolt 2.

The lock body includes a base 11, and a cover plate 12 covering the base 11. The lock body is internally provided with a lock bolt cavity 13, a left cavity 14 and a right cavity 15 which are positioned at two sides of the lock bolt cavity 13 and communicated with the lock bolt cavity 13. The lock body is characterized in that a lock tongue hole and a rope hole 16 which are communicated with two ends of the lock tongue cavity 13 are arranged on the side wall of the lock body, and a through hole 17 which is communicated with at least one of the left cavity 14 and the right cavity 15 is also arranged on the lock body. The bolt 2 is in the bolt cavity 13, and the working end of the bolt 2 can extend out of the bolt hole. The lock tongue spring 3 is positioned in the lock tongue cavity 13 and is propped against the inner end part of the lock tongue 2; the motor wire and the switch signal wire in the intelligent unlocking system can be led out from the through wire holes 17 at two ends or centralized to be led out from the through wire holes 17 at one end.

The intelligent unlocking system comprises a motor 5, an intelligent unit for driving the motor 5 to work, and a cam assembly 4 connected to an output shaft of the motor 5. The motor 5 and the cam component 4 are arranged in the left cavity 14, the bolt 2 is provided with a first bolt slot 21, and the output end of the cam component 4 is arranged in the first bolt slot 21 and abuts against the side wall of one side to limit the axial position of the bolt 2. In one embodiment, the cam assembly 4 includes a disc 41 connected to the output shaft of the motor 5, and a leg 42 disposed on the disc 41. The leg 42 is disposed off-axis of the disc body 41, and the leg 42 is disposed in the first latch groove 21 as an output end of the cam member 4. In this technical scheme, spring 3 acts on spring bolt 2 and makes it outside the lock body, and intelligent unit in the intelligence system of unblanking is used for receiving external instruction and judges whether legal instruction, like fingerprint identification, card swiping, password and remote control etc. motor 5 is as carrying out power, drives cam module 4 application during the electrode motion, and cam module 4's output limits spring bolt 2's axial position. In the cam assembly 4, the axis of the disc body 41 is connected to the output shaft of the motor 5, the motor 5 drives the disc body 41 to rotate, so that the support leg 42 at the non-axis of the disc body 41 generates displacement above the axial direction of the bolt 2, and the bolt 2 correspondingly generates axial movement, thereby realizing unlocking or locking action. In a further preferred scheme, the intelligent unlocking system further comprises a limit switch 6, the limit switch 6 is located in the right chamber 15, and the limit switch 6 monitors the limit position of the axial movement of the bolt 2 and sends a shutdown command to the intelligent unit. And a second lock tongue groove 22 is formed in the lock tongue 2, and the trigger end of the limit switch 6 is positioned in the second lock tongue groove 22. When the trigger end of the limit switch 6 is contacted with the side wall of the second lock tongue groove 22, a stop instruction is sent; the axial movement limit position of the bolt 2 is monitored through the limit switch 6, and the motor 5 is controlled to stop in time.

The working end of the bolt 2 is an inclined plane, the intelligent unlocking system can enable the motor 5 to rotate reversely after unlocking for several seconds, and the bolt 2 rebounds to the original position under the action of the bolt spring 3. The user need open drawer or cabinet door in this period of time, and even if spring bolt 2 has reset when drawer or cabinet door open mode, because the work end of spring bolt 2 is the inclined plane. In the closing process, the drawer or the cabinet door is pushed and pressed, the lock catch presses the inclined plane of the head of the bolt 2, the exposed part of the head of the bolt 2 retracts into the lock body, and the drawer or the cabinet door is smoothly pushed in.

In addition, intelligence cabinet lock still includes cable 7, and the interior tip of cable 7 is connected on spring bolt 2, and the other end (outer tip) of cable 7 stretches out the lock body. The pulling cable 7 passes through a cable hole 16 of the lock body, and the pulling force of the pulling cable 7 on the bolt 2 is opposite to the elastic force of the bolt spring 3 on the bolt 2. When the guy cable 7 pulls the bolt 2, the first bolt slot 21 moves relative to the output end of the cam component 4. And the axial length of the first bolt groove 21 on the bolt 2 needs to ensure that the bolt 2 can fully extend into the lock body. When intelligence system of unblanking damages and spring bolt 2 is in the shutting state, need pass through cable 7 pulling spring bolt 2 motion, and need guarantee under this condition that cable 7 pulls spring bolt 2 and can not be obstructed by cam subassembly 4, consequently need adopt cam subassembly 4's output to offset with the unilateral lateral wall of first spring bolt groove 21 among this technical scheme and be used for restricting the axial position of spring bolt 2 to the axial length of first spring bolt groove 21 on spring bolt 2 needs to guarantee that spring bolt 2 can stretch into in the lock completely. In the above scheme, the outer end of the inhaul cable 7 can be connected with a mechanical lock head, namely, an intelligent unlocking system and a mechanical lock combined mode are adopted.

Under the locking state, the intelligent unit inputs correct information, the motor 5 rotates, a crankshaft shifting head of a cam component 4 arranged on a main shaft of the motor 5 is turned from a high point to a low point, the bolt 2 is pulled to move towards the inside of the lock body until the bolt 2 is completely retracted into the lock body, the bolt 2 is separated from the lock catch, at the moment, the bolt 2 presses the limit switch 6 and the limit switch 6 to send out a signal for opening the lock body in place, and the intelligent system instructs the motor 5 to stop rotating. At the moment, the lock is opened, the drawer or the cabinet door can be opened, after 5 seconds of delay, the motor 5 automatically rotates in the reverse direction, a crankshaft shifting head of the cam component 4 is turned to a high point from a low point, the spring bolt 2 rebounds to the original position again under the action of the spring bolt 3 (the inclined plane of the head of the spring bolt 2 is higher than the end face of the lock body), the spring bolt 2 is separated from the limit switch 6 to send a locked signal, the drawer or the cabinet door is pushed and pressed, the lock catch presses the inclined plane of the head of the spring bolt 2, the exposed part of the head of the spring bolt 2 retracts into the lock body, when the drawer or the cabinet door is pressed in place, the position of the spring bolt 2 and the hole in the lock catch is aligned.

Above-mentioned embodiment relates to an intelligence cabinet lock, adopts intelligent system of unblanking to control in this intelligence cabinet lock the motion of spring bolt 2 to convenient to use, theftproof performance are good's purpose. Further, still be provided with cable 7 in this intelligence cabinet lock, spring bolt 2 is connected to 7 one end of cable, and one end stretches out the lock body outside. When intelligence system of unblanking became invalid, can exert in cable 7 through external force, cable 7 pulls spring bolt 2 and opens the cabinet lock. This scheme adopts comparatively simple mechanical structure on the whole to be used for emergent opening to combine mechanical lock and intelligent lock, remain convenience, theftproof nature and the opening mode variety of intelligent lock.
