Description

Technical Field

[0001] The present invention relates to the technical field of distribution box locks, and particularly to an intelligent distribution box lock with a cam clutch drive and high power transmission efficiency. Background Art

[0002] With the continuous progress and innovation of power technology, the application scenarios of distribution box equipment have become increasingly diverse, ranging from residential communities to large industrial facilities, and then to data centers and new energy sites, all of which demonstrate its importance. In terms of scientific management and safe power use, the performance and reliability of distribution boxes are directly related to the stable operation of the power system and personnel safety, so it has attracted great attention from all sectors of society. However, the current application of distribution box equipment still faces some significant deficiencies and challenges.

[0003] 1. Existing various AC distribution boxes widely use mechanical pressing locks for control, which cannot perform identity verification and permission identification of the opening personnel. Moreover, each distribution box needs to carry a physical key to unlock, resulting in poor convenience and background controllability.

[0004] 2. The existing intelligent idle-turn cabinet locks are large in size and cannot be directly used on distribution boxes. Moreover, the internal transmission mechanism mostly uses a spring plus bolt propulsion structure. After the elasticity of the spring decreases, the bolt cannot be effectively pushed into the handle linkage mechanism, resulting in low unlocking efficiency. This structure is complex, occupies a large space, and has a high cost.

[0005] Therefore, aiming at the problems that the traditional distribution box locks lack identity verification and background control, the existing cabinet locks are large in size and cannot be directly applied, and their internal structure is complex, with a high failure rate and low unlocking efficiency, an intelligent distribution box lock with a cam clutch drive and high power transmission efficiency can be designed. Summary of the Invention

[0006] In order to solve the problems that the traditional distribution box locks lack identity verification and background control, the existing cabinet locks are large in size and cannot be directly applied, and their internal structure is complex and the unlocking efficiency is low.

[0018] Advantages of the present invention:

[0019] 1. The intelligent distribution box lock with a cam clutch drive and high power transmission efficiency has two unlocking methods. The first is to unlock with a Bluetooth key. After authorizing the Bluetooth key using a management program such as a mobile phone APP, insert the Bluetooth key into the idle lock cylinder. Turning the key drives the first cam to rotate, which in turn drives the paddle to swing up and down, causing the clutch shaft to engage with the rotating shaft. Turning the handle can drive the bolt to rotate and achieve unlocking. The power supply time is preset in the Bluetooth key program. After the power supply time expires, the Bluetooth key stops supplying power to the idle lock cylinder. The first cam resets under the action of the torsion spring, and the pulling force of the tension spring drives the paddle to swing, causing the clutch shaft to separate from the rotating shaft, and the handle rotates idly. The internal component movement states during the locking process are the same as those during the unlocking process, and the handle can be rotated in the reverse direction. The second is to unlock remotely. The background management program (the cloud management APP on a remote computer) sends an unlocking instruction to the remote control board in the lock body. After receiving the instruction, the control board converts it into power supply to the motor. The motor drives the second cam to rotate, which in turn drives the paddle to swing up and down, causing the clutch shaft to engage with the rotating shaft. Turning the handle can drive the bolt to rotate and achieve unlocking. When locking, the box door presses the door magnetic switch, and the door magnetic switch transmits the door magnetic signal to the remote control board. At this time, the clutch shaft is still engaged with the rotating shaft. Reverse the handle until the remote control board detects the bolt position signal, then the remote control board supplies power to the motor, and the motor rotates in reverse to drive the second cam to rotate in reverse until the second low surface contacts the second convex column and stops. At this time, the paddle swings under the action of the tension spring, causing the U-shaped fork on the paddle to drive the clutch shaft to move to the right, so that the clutch shaft separates from the rotating shaft, and the handle is in an idle rotation state, and the locking is successful. At the same time, the remote control board sends the door magnetic and bolt position signals to the background management program, and the door magnetic and bolt states can be viewed on the background management program to ensure the locking is successful. The intelligent remote unlocking adds security information such as identity recognition and permission management. Compared with the traditional mechanical pressing lock, it effectively improves the security of the distribution box, avoids the occurrence of electricity theft behavior, and at the same time, the remote unlocking greatly facilitates the unlocker to unlock, avoiding the inconvenience of unlocking caused by carrying a physical key and key loss.

[0020] 2. The cam clutch-driven intelligent distribution box lock with high power transmission efficiency has a cam clutch structure provided. When unlocking, the first cam or the second cam is rotated by the idle lock cylinder or the motor, so that the first high surface on the first cam contacts the first convex column on the paddle or the second high surface on the second cam contacts the second convex column on the paddle, the paddle swings around the second pin, and the U-shaped fork on the paddle drives the clutch shaft to move left, so that the clutch shaft engages with the rotating shaft, and the handle can be turned to unlock. On the contrary, when locking, the first cam or the second cam is reversed by the idle lock cylinder or the motor, so that the first low surface on the first cam contacts the first convex column on the paddle or the second low surface on the second cam contacts the second convex column on the paddle, the paddle swings around the second pin, and the U-shaped fork on the paddle drives the clutch shaft to move right, so that the clutch shaft is separated from the rotating shaft, and the handle is idle. The cam clutch mechanism used in this lock not only has high power transmission efficiency, but also has a simple structure, small space occupation, and low cost. Compared with the traditional spring latch propulsion mechanism, it has a higher cost performance. BRIEF DESCRIPTION OF THE DRAWINGS

The motor 10 is fixedly installed in the fourth cavity 504 of the lock body 5. A second cam 12 is fixedly installed at the output end of the motor 10. The second cam 12 includes a second high surface 1201 and a second low surface 1202. After the motor 10 receives an instruction, it can drive the second cam 12 to rotate 180°, so as to realize the switching between the second high surface 1201 and the second low surface 1202. The dial bracket 8 is fixedly installed in the fourth cavity 504. The dial bracket 8 is rotatably connected to a dial 21 through a second pin shaft 7. The dial 21 can swing up and down around the second pin shaft 7. A tension spring 16 is also connected between the dial 21 and the dial bracket 8. When not working, the tension spring 16 is in a natural state, and when working, the tension spring 16 is in a stretched state. The clutch shaft 18 is arranged in the second cavity 502. A U-shaped fork 2101 is arranged in the circumferential groove 1803 on the clutch shaft 18. The front end of the dial 21 is provided with a U-shaped fork 2101, and the rear end is successively provided with a first convex column 2102 and a second convex column 2103. The end of the first convex column 2102 contacts the top surface of the first cam 13, and the end of the second convex column 2103 contacts the top surface of the second cam 12. The U-shaped fork 2101 can swing left and right in the circumferential groove 1803 on the clutch shaft 18, thereby driving the clutch shaft 18 to move left and right.

The first cylindrical shaft 1802 on the end face of the second clutch tooth 1801 is sleeved and slidable left and right in the first cylindrical cavity 405 on the end face of the first clutch tooth 401. When the second high surface 1201 of the second cam 12 contacts the second convex post 2103, the U-shaped fork 2101 arranged on the dial 21 swings to the left, thereby driving the clutch shaft 18 to move to the left. At the same time, the second clutch tooth 1801 on the clutch shaft 18 meshes with the first clutch tooth 401 on the rotating shaft 4 to realize clutch rotation. At this time, turning the handle 1 can drive the clutch shaft 18 to rotate. On the contrary, when the second low surface 1202 of the second cam 12 contacts the second convex post 2103, the U-shaped fork 2101 arranged on the dial 21 swings to the right, thereby driving the clutch shaft 18 to move to the right. At the same time, the second clutch tooth 1801 on the clutch shaft 18 separates from the first clutch tooth 401 on the rotating shaft 4 to realize clutch separation. At this time, the handle 1 is in an idle state. A rotating shaft connecting block 23 is rotatably installed at the right end in the second cavity 502. The rotating shaft connecting block 23 includes a first boss 2301, a second boss 2302 and a first square boss 2303.

The rear cover plate 25 is fixedly connected to the rightmost end of the lock body 5 by a second screw 26. The second boss 2302 on the rotating shaft connecting block 23 passes through the first through hole 2501. The diameter of the second boss 2302 is smaller than that of the first through hole 2501. After the rear cover plate 25 is fixedly installed, the rotating shaft connecting block 23 can rotate circumferentially and is axially limited in the second cavity 502 of the lock body 5. An installation back plate 27 is arranged on the right side of the box door panel 6. The installation back plate 27 is fixed to the lock body 5 by a third screw 29. The installation back plate 27 is provided with a second through hole 2701, a fifth cavity 2702, a sixth cavity 2703 and a first limiting platform 2704. By tightening the third screw 29, the box door panel 6 can be tightly clamped between the lock body 5 and the installation back plate 27 to fix the lock body 5 on the box door panel 6. The remote control board 22 is installed in the fourth cavity 504 on the lock body 5. The start and stop of the motor 10 can be controlled through the remote control board 22 to realize functions such as remote control and monitoring of the state of the magnetic lock tongue.,

[0028] When working, two unlocking methods can be provided: unlocking with a Bluetooth key and remote unlocking. 1. Unlocking with a Bluetooth key: When an authorized Bluetooth key is inserted into the idle lock cylinder 9 and rotated, the idle lock cylinder 9 is driven to rotate, thereby driving the first cam 13 and the first torsion spring 11 to rotate. When the first step 1301 on the first cam 13 contacts the lock body and stops, at this time, the first high surface 1303 contacts the first protrusion 2102 on the dial 21. The U-shaped fork 2101 on the dial 21 drives the clutch shaft 18 to move leftward, so that the clutch shaft 18 meshes with the rotating shaft 4. Rotating the handle 1 can rotate the bolt away from the lock catch to achieve unlocking. The power-on holding time is preset in the Bluetooth key. When the time expires, the Bluetooth key stops supplying power to the idle lock cylinder 9. At this time, the first cam 13 reversely rotates and resets under the action of the first torsion spring 11, and the dial 21 swings under the action of the tension spring 16. At the same time, the first low surface 1302 contacts the first protrusion 2102, and the U-shaped fork 2101 on the dial 21 drives the clutch shaft 18 to move rightward, so that the clutch shaft 18 is separated from the rotating shaft 4, and the handle 1 is in an idle state. The movement states of each component during the locking process are the same as those during the unlocking process. Just reverse the handle 1. 2. Remote unlocking: When a remote terminal device such as a computer sends an unlocking instruction to the remote control board 22 through the access control management program, the remote control board 22 supplies power to the motor 10. The motor 10 drives the second cam 12 to rotate until the second high surface 1201 contacts the second protrusion 2103 and stops. At this time, the U-shaped fork 2101 on the dial 21 drives the clutch shaft 18 to move leftward, so that the clutch shaft 18 meshes with the rotating shaft 4. Rotating the handle 1 can rotate the bolt away from the lock catch to achieve unlocking. When locking, after closing the distribution box door by hand, the box door presses the door magnetic switch, and the door magnetic switch transmits a door magnetic signal to the remote control board 22. At this time, the clutch shaft 18 still meshes with the rotating shaft 4. Reverse the handle 1 to make the bolt approach the lock catch until the remote control board 22 detects the bolt position signal. Then the remote control board 22 supplies power to the motor 10, and the motor 10 reversely rotates to drive the second cam 12 to reverse until the second low surface 1202 contacts the second protrusion 2103 and stops. At this time, the dial 21 swings under the action of the tension spring 16, so that the U-shaped fork 2101 on the dial 21 drives the clutch shaft 18 to move rightward, so that the clutch shaft 18 is separated from the rotating shaft 4, and the handle 1 is in an idle state, and the locking is successful.

[0029] Regardless of the unlocking or locking method, the power transmission inside the lock body is from the first cam 13 or the second cam 12 to the dial 21. The swinging of the dial 21 drives the engagement and separation of the clutch shaft 18 and the rotating shaft 4. This clutch device adopts a cam-linkage mechanism, which makes the transmission efficiency higher and the reliability higher. At the same time, this mechanism has a simple structure, occupies a small space, and saves the occupied area.

[0030] Through the above steps, the lock has an intelligent remote unlocking management function, and realizes the dual unlocking methods of Bluetooth key and remote cloud management APP, which not only greatly improves the safety of the distribution box and effectively prevents electricity theft, but also greatly facilitates the operation of the unlocking personnel, avoids the problem of carrying and losing the physical key, and further enhances the safety and convenience of the system through the addition of identity recognition and authority management. At the same time, the cam clutch structure provided, with its efficient power transmission, simple structural design, small footprint and low cost, shows a higher cost performance than the traditional spring latch propulsion mechanism. During the unlocking and locking process, the structure realizes the rapid engagement and separation of the clutch shaft and the rotating shaft through the rotation of the cam and the swing of the paddle. The operation is simple and stable, which can solve the problems of the lack of identity authentication and background control of the traditional mechanical push-type distribution box lock, the existing cabinet lock is large in size, cannot be directly applied, and has a complex internal structure, low power transmission efficiency, and low unlocking efficiency.
