Description

Technical Field

[0001] This utility model relates to the field of lock technology, and more specifically, to a three-point communication free-spinning padlock cylinder. Background Technology

[0002] A free-spinning lock cylinder is a type of anti-theft lock cylinder, mainly used in security protection fields such as anti-theft doors. It consists of components such as a shell, lock cylinder, blades, pins, and clutch mechanism.

[0003] Based on the above, the inventors have discovered that traditional single-point communication idle-spinning padlock cylinders generally have low communication efficiency and poor communication stability, especially in scenarios with complex encryption algorithms, such as the SM4 online asymmetric algorithm, where the amount of encrypted data is large and the single-point communication structure cannot meet the requirements. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a three-point communication idle-spinning padlock cylinder, aiming to achieve a more practical purpose.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A three-point communication idle padlock cylinder includes a lock shell. One end of the lock shell is open, and a lock cover is fixedly connected to the opening. The other end of the lock shell has an integrally formed boss. A main control board and a drive motor are fixedly installed inside the lock shell, and the main control board and the drive motor are electrically connected via wires. The lock cover has a lock cylinder hole, and an insulating seat is installed in the lock cylinder hole. The insulating seat has a first contact, a second contact, and a third contact that are electrically connected to the main control board. The output shaft of the drive motor extends into the boss and is connected to a cam via a key. Steel balls are embedded on both sides of the boss, and the steel balls are in contact with the outer periphery of the cam.

[0009] Furthermore, the first contact is a positive contact, the second contact is a common negative contact, and the third contact is a communication contact.

[0010] Furthermore, the first contact, the second contact, and the third contact are evenly distributed at equal intervals.

[0011] Furthermore, grooves are provided on both sides of the cam, and the steel ball is adapted to the corresponding groove.

[0012] Furthermore, limiting holes are provided on both sides of the boss, and the steel ball is embedded in the corresponding limiting hole.

[0013] Furthermore, a connecting plate is fixedly connected to one end of the drive motor near the boss. A limit rod is integrally formed on one side of the connecting plate, and a limit groove is opened on the outer side of the cam. One end of the limit rod extends into the limit groove.

[0014] Furthermore, two symmetrical positioning blocks are fixedly connected to the outer periphery of the lock cover near the lock housing. A positioning groove is provided on the outer periphery of the lock housing corresponding to the position of the positioning block, and the corresponding positioning block is engaged in the positioning groove.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) This solution achieves efficient communication through a unique structural design. The electrical connection between the main control board and the drive motor enables the lock cylinder to have the power and control foundation. At the same time, the first contact is used as the positive contact, the second contact is used as the common negative contact, and the third contact is used as the communication contact. This design optimizes the current transmission and communication path. The three contacts are evenly distributed at equal intervals, which ensures the stability and consistency of signal transmission and avoids signal interference or poor transmission due to the contact spacing problem.

[0018] (2) In this design, the grooves on both sides of the cam are adapted to fit the steel balls, and the limiting holes on both sides of the boss are fitted with the steel balls. With this structure, the steel balls can move smoothly in the grooves when the cam rotates, while the limiting holes position the steel balls to prevent them from falling out, thus ensuring the stability of the lock cylinder's mechanical structure. The connecting plate and limiting rod fixedly connected to one end of the drive motor cooperate with the limiting groove on the outer side of the cam to further precisely control the rotation angle and position of the cam, improving the accuracy of the lock cylinder's operation. At the same time, the lock cover and lock shell are connected by the positioning block and positioning groove, which facilitates installation and disassembly and enhances the overall structural stability.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0043] Example:

[0044] Please see Figures 1-4 The three-point communication idle padlock cylinder includes a lock shell 1. One end of the lock shell 1 is open, and a lock cover 2 is fixedly connected to the opening. The other end of the lock shell 1 has an integrally formed boss 3. A main control board 4 and a drive motor 5 are fixedly installed inside the lock shell 1, and the main control board 4 and the drive motor 5 are electrically connected by wires. The lock cover 2 has a lock cylinder hole 6, and an insulating seat 7 is installed in the lock cylinder hole 6. The insulating seat 7 is equipped with a first contact 8, a second contact 9, and a third contact 10 that are electrically connected to the main control board 4. The output shaft of the drive motor 5 extends into the boss 3 and is connected to a cam 11 by a key. Steel balls 12 are embedded on both sides of the boss 3, and the steel balls 12 are in contact with the outer periphery of the cam 11.

[0045] See Figure 3 and Figure 4 The first contact 8 is the positive contact, representing the positive power supply, 3.7V power supply; the second contact 9 is the common negative contact, representing the common negative terminal; and the third contact 10 is the communication contact, indicating that the data to be sent and received with the key is transmitted through this contact.

[0046] See Figure 4 The first contact 8, the second contact 9, and the third contact 10 are evenly distributed at equal intervals, which can ensure the stability and consistency of signal transmission during use and avoid signal interference or poor transmission due to contact spacing issues.

[0047] See Figure 2 The cam 11 has grooves 13 on both sides, and the steel ball 12 is adapted to the corresponding grooves 13. The boss 3 has limit holes on both sides, and the steel ball 12 is embedded in the corresponding limit holes. With the grooves 13 on both sides of the cam 11 adapted to the steel ball 12, and the limit holes on both sides of the boss 3 embedded with the steel ball 12, the steel ball 12 can move smoothly in the grooves 13 when the cam 11 rotates. At the same time, the limit holes play a positioning role for the steel ball 12, preventing the steel ball 12 from falling out and ensuring the stability of the lock cylinder mechanical structure.

[0048] See Figure 2 A connecting plate 14 is fixedly connected to one end of the drive motor 5 near the boss 3. A limit rod 15 is integrally formed on one side of the connecting plate 14. A limit groove 16 is opened on the outer side of the cam 11. One end of the limit rod 15 extends into the limit groove 16.

[0049] See Figure 1 and Figure 2Two symmetrical positioning blocks 17 are fixedly connected to the outer periphery of the lock cover 2 near the lock shell 1. A positioning groove 18 is provided on the outer periphery of the lock shell 1 at the position corresponding to the positioning block 17, and the corresponding positioning block 17 is engaged in the positioning groove 18. The lock cover 2 and the lock shell 1 are engaged by the positioning block 17 and the positioning groove 18, which facilitates installation and disassembly and enhances the stability of the overall structure.

[0050] In use: Insert the electronic key into the lock cylinder hole 6. The electronic key corresponds to three contacts. The electronic key first supplies power to the main control board 4 through the first contact 8 and the second contact 9. After powering on, it analyzes whether the key number is allowed to open the lock. If the match is successful, the main control board 4 circuit supplies power to the drive motor 5. After the drive motor 5 starts, its drive shaft drives the cam 11 to rotate to the stall position. The stalled cam 11 pushes out the steel ball 12, which will lock the external clutch. Rotating the entire lock cylinder will open the lock. The overall communication stability and efficiency are greatly improved, reducing signal interruption, bit error and other problems, ensuring the accuracy of data transmission, and effectively improving the reliability of the lock in the field of security protection.
