Description

Technical Field

[0001] This application relates to the field of lock, particularly to a type of padlock.Background Art

[0002] The market is filled with a wide variety of locks, such as chain locks, wire rope locks, joint locks, padlocks, etc. However, most locks only achieve locking and unlocking through simple mechanical lock structures, which are not secure enough. Due to the lack of electronic alarm functions in these types of locks, they can be easily pried open by criminals from the outside in unattended environments. This neither alerts the user in a timely manner nor deters criminals, resulting in relatively poor anti-theft performance.Summary of the Invention

[0018] In In the following, only some exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be essentially exemplary rather than limiting.

[0019] As shown in Figures 1 to 13, the embodiments of this application provide a padlock, including a lock shell 1, a lock body main unit 2, and a lock rod assembly 3 that works in conjunction with the lock body main unit 2. The lock shell 1 has a containment cavity 11, and the lock body main unit 2 is located within the containment cavity 11. The padlock also includes a lock cylinder 4, a first sensor 5, an electronic component 6, a fixing assembly 7, and an alarm component 8. The lock cylinder 4 is installed on the lock body main unit 2, with the first sensor 5 set on the lock cylinder 4. The lock cylinder 4 has a first keyhole 40, which is used to insert a key for locking or unlocking. The electronic component 6 is installed within the containment cavity 11, located on one side of the lock cylinder 4, with a second sensor set on the electronic component 6. One of the first sensor 5 and the second sensor is a transmitter, while the other is a receiver. The fixing assembly 7 includes a fixing piece 71 and an elastic piece 72. The electronic component 6 has a first fixing hole 61, with both the fixing piece 71 and the elastic piece 72 placed within the first fixing hole 61. One end of the elastic piece 72 abuts against the bottom of the first fixing hole 61, while the other end abuts against one end of the fixing piece 71. The lock shell 1 has a second fixing hole 121, and the other end of the fixing piece 71 protrudes from the electronic component 6 and is placed within the second fixing hole 121. The alarm component 8 is installed on the electronic component 6 and is electrically connected to either the first sensor 5 or the second sensor.

[0020] The padlock in the embodiments of this application includes a lock shell 1, a lock body main unit 2, a lock rod assembly 3, a lock cylinder 4, a first sensor 5, an electronic component 6, a fixing assembly 7, and an alarm component 8. The first sensor 5 is set on the lock cylinder 4, and the electronic component 6 has a second sensor. One of the first sensor 5 and the second sensor is a transmitter, while the other is a receiver. The alarm component 8 is electrically connected to either the first sensor 5 or the second sensor. During the process of turning the lock cylinder 4 with a key, the distance between the first sensor 5 and the second sensor changes. Alarm conditions are set based on the change in distance between the first sensor 5 and the second sensor. Through the setup of the first sensor 5, second sensor, and alarm component 8, the user can be promptly alerted when the padlock is being tampered with, which can also deter criminals and improve anti-theft performance.

[0021] In one embodiment, the first sensor 5 can be a receiver and the second sensor can be a transmitter; or the first sensor 5 can be a transmitter and the second sensor can be a receiver. When the first sensor 5 is a transmitter, it can be a magnetic field emitting device, specifically, the magnetic field emitting device can be a magnet, used to generate a magnetic field. The second sensor can be a magnetic field receiving device, used to detect the magnetic field produced by the magnet and generate corresponding electromagnetic signals.

[0022] Since the magnet is set on the lock cylinder 4, as the lock cylinder 4 rotates, the magnet also rotates with it, changing the position of the magnet and causing a change in the relative position between the magnet and the magnetic field receiving device. When the padlock is in an unlocked state, the distance between the magnet and the magnetic field receiving device is at its farthest, resulting in the weakest signal received by the magnetic field receiving device. When in a locked state, the distance between the magnet and the magnetic field receiving device is at its closest, and the magnetic field receiving device receives the strongest signal. This embodiment can set up alarms based on the changes in signal strength received by the magnetic field receiving device. The alarm component 8 determines whether to trigger an alarm based on the changes in electromagnetic signals. The alarm component 8 includes a speaker 81 and a vibration sensor.

[0023] In one embodiment, to achieve the installation of the first sensor 5, the lock cylinder 4 includes a lock core 41, a cylinder shell 42, and a lock plate 43. The lock core 41 is installed inside the cylinder shell 42, and the lock plate 43 is installed on the lock core 41. The lock core 41 and the lock plate 43 rotate axially within the cylinder shell 42. A rotating pin 44 is also installed on the lock core 41, which works in conjunction with the lock plate 43. The lock core 41 is made of high-strength alloy steel material, and there is a cylindrical blind hole 45 on the side of the lock core 41. The first sensor 5 is installed inside this blind hole 45. The first keyhole 40 is located on the lock plate 43.

[0024] To achieve the installation of the lock cylinder 4 on the lock body main unit 2, the lock body main unit 2 includes a lock body 21. The lock body 21 has a lock cylinder installation slot 211 that runs through the lock body 21 from top to bottom. The lock cylinder 4 is installed within this lock cylinder installation slot 211. To secure the lock cylinder 4 within the lock cylinder installation slot 211, along the length of the cylinder shell 42, there is a fixed protrusion 46 on its outer surface. The inner wall of the lock cylinder installation slot 211 has a fixed recess 212, and the fixed protrusion 46 is placed within this fixed recess 212. The cylinder shell 42 is secured through the fixed protrusion 46 and the fixed recess 212, preventing the cylinder shell 42 from rotating when the lock core 41 and lock plate 43 rotate.

[0025] In one embodiment, to limit the movement of the lock core 41, there is a first limiting post 47 and a second limiting post 48 on the lock core 41. Along the circumference of the cylinder shell 42, there is a first limiting groove 421, and along the circumference of the lock cylinder installation slot 211, there is a fixed recess 212 on the inner wall. The first limiting post 47 moves within the first limiting groove 421, and the second limiting post 48 moves within the fixed recess 212. Since the first limiting post 47 is within the first limiting groove 421, and the second limiting post 48 is within the fixed recess 212, during the movement of the lock core 41, the movement is limited by the interaction between the first limiting post 47 and the first limiting groove 421, as well as the second limiting post 48 and the second limiting groove 212.

[0026] In one embodiment, the fixing assembly 7 also includes a fixing end cap 73, installed within the first fixing hole 61. Preferably, the fixing end cap 73 can be installed within the first fixing hole 61 through methods such as threaded connection. The center of the fixing end cap 73 has a limiting hole 731, and the fixing end cap 73 has a first limiting part 732. The fixing piece 71 is fitted with a second limiting part 74, and the elastic piece 72 is fitted on one end of the fixing piece 71. The second limiting part 74 is between the first limiting part 732 and the elastic piece 72, with the second limiting part 74 abutting against the first limiting part 732. The second limiting part 74 limits the elastic piece 72, while the first limiting part 732 limits the fixing piece 71, preventing the fixing piece 71 from moving out of the first fixing hole 61. The lock shell 1 has a second fixing hole 121, and the other end of the fixing piece 71 passes through the first fixing hole 61 and is placed within the second fixing hole 121. Preferably, the elastic piece 72 is a spring.

[0027] Furthermore, to achieve the installation of the electronic component 6, the lock body 21 has an installation cavity 213, and the electronic component 6 is installed within this installation cavity 213. The lock body 21 has elastic mounting grooves 214 on two opposite sides, with springs 218 installed in each of these elastic mounting grooves 214. One end of the spring 218 abuts against the inner wall of the elastic mounting groove 214, while the other end abuts against one end of the electronic component 6. Preferably, one end of the spring 218 is connected to the inner wall of the elastic mounting groove 214.

[0028] When installing the electronic component 6, first press the fixing piece 71 to move it into the first fixing hole 61, then push the electronic component 6 into the lock shell 1 from one end. Once the electronic component 6 is in place, the other end of the fixing piece 71 moves into the second fixing hole 121 under the elastic force of the elastic piece 72, thus securing the electronic component 6. When the electronic component 6 is in the locked state, both springs 218 are in a compressed state. The installation of the electronic component 6 can be achieved without tools, making the installation method convenient and quick.

[0029] When it's necessary to remove the electronic component 6, use a steel needle or other tool to press the other end of the fixing piece 71, disengaging it from the second fixing hole 121. At this point, under the elastic force of the two springs 218, the electronic component 6 will be pushed out from the lock shell 1 towards one end, causing it to automatically eject from the lock shell 1, thus facilitating its removal. The electronic component 6 is equipped with a battery that powers the second sensor and the alarm component 8. After removing the electronic component 6, it's convenient to replace the battery or recharge it.

[0030] In one embodiment, to achieve the locking or unlocking of this padlock, the lock body main unit 2 also includes a first lock tongue 22 and a second lock tongue 23. The first lock tongue 22 and the second lock tongue 23 are installed on the lock body 21, with the lock core 41 connected to both. The lock core 41 drives the first lock tongue 22 and the second lock tongue 23 to move towards or away from each other on the lock body 21. The first lock tongue 22 and the second lock tongue 23 are made of high-strength alloy steel material.

[0031] The lock body 21 has two first lock rod insertion holes 215, with the first lock tongue 22 and the second lock tongue 23 positioned between these two holes. The lock rod assembly 3 includes two connected lock rods 31, which form a U-shaped structure when connected. Each of the two lock rods 31 has a locking hole 311. The ends of the first lock tongue 22 and the second lock tongue 23 that face away from each other are each fitted with a locking pin 24. After the two lock rods 31 are inserted into the two first lock rod insertion holes 215, the lock core 41 drives the first lock tongue 22 and the second lock tongue 23 to move apart, causing the two locking pins 24 to insert into the two locking holes 311 for locking. In this embodiment, the lock rods 31 are also made of high-strength alloy steel. The locking pins 24 can be cylindrical or other shapes.

[0032] To drive the movement of the first lock tongue 22 and the second lock tongue 23, there are two drive pins 49 on the top of the lock core 41. The ends of the first lock tongue 22 and the second lock tongue 23 that face each other are each fitted with a drive slot 25. The two drive pins 49 are positioned within these two drive slots 25. When the lock core 41 rotates, it drives the first lock tongue 22 and the second lock tongue 23 to move towards or away from each other on the lock body 21 through the two drive pins 49 and the two drive slots 25. To limit the movement of the first lock tongue 22 and the second lock tongue 23, there are two moving limiting grooves 216 on the lock body 21. The two drive pins 49 are positioned within these two moving limiting grooves 216, which limit the movement of the first lock tongue 22 and the second lock tongue 23.

[0033] When unlocking, the key is inserted into the first keyhole 40. As the key turns, it rotates the lock core 41 inside the cylinder shell 42. As the lock core 41 rotates, it drives the first lock tongue 22 and the second lock tongue 23 to move towards each other through the two drive pins 49, withdrawing the locking pins 24 on the first lock tongue 22 and the second lock tongue 23 from the two locking holes 311, thus releasing the two lock rods 31. At this point, the two lock rods 31 can freely enter and exit the two first lock rod insertion holes 215, allowing the lock rod assembly 3 and the lock body main unit 2 to be freely separated. When locking, the key is inserted into the first keyhole 40, and the key rotates the lock core 41 in the opposite direction inside the cylinder shell 42. The lock core 41 drives the first lock tongue 22 and the second lock tongue 23 to move away from each other through the two drive pins 49, inserting the two locking pins 24 on the first lock tongue 22 and the second lock tongue 23 into the two locking holes 311 respectively to achieve locking. At this point, the lock rods 31 cannot be pulled out from the two first lock rod insertion holes 215.

[0034] In one embodiment, to achieve the locking of the lock rod assembly 3 with the lock body 21, there are flat catch areas 312 at the bottom of the two lock rods 31. The lock body 21 has two fixed catch holes 217. After the bottoms of the two lock rods 31 are inserted into the two fixed catch holes 217, the flat catch areas 312 engage with the sides of the fixed catch holes 217. The flat catch areas 312 and the locking holes 311 are located on different sides of the lock rods 31. Through the setup of the flat catch areas 312 and the locking holes 311, even if the lock rod 31 is sawed through, it cannot be opened by rotation, further improving the security of the padlock.

[0035] In one embodiment, the lock shell 1 includes a main lock tube body 12, a first lock tube 13, and a second lock tube 14. The containment cavity 11 is located inside the main lock tube body 12. The first lock tube 13 and the second lock tube 14 are fitted over the two ends of the main lock tube body 12 respectively, connected to the main lock tube body 12 by bolts. The second fixing hole 121 is located on the main lock tube body 12. The first lock tube 13 and the second lock tube 14 each have a second lock rod insertion hole 15. The main lock tube body 12 has two third lock rod insertion holes 16 that correspond to the two second lock rod insertion holes 15. The positions of the two third lock rod insertion holes 16 correspond to the positions of the two first lock rod insertion holes 215. There is a fourth lock rod insertion hole 62 on the electronic component 6, which corresponds to the position of one of the first lock rod insertion holes 215.

[0036] When unlocking the padlock in this application's embodiment, the distance between the first sensor 5 and the second sensor is at its farthest, resulting in the weakest signal received by the second sensor, and the anti-theft alarm is deactivated. When locking, the distance between the first sensor 5 and the second sensor is at its closest, with the second sensor receiving the strongest signal. At this point, the alarm can be set to either activate or remain in a non-alarm state. Once the alarm is activated, if there's any external force shaking or hitting the padlock, the alarm component 8 will continuously emit warning sounds. In the non-alarm state, external forces shaking or hitting the padlock will not trigger the alarm.

[0037] The electronic component 6 and alarm component 8 of the padlock in this application's embodiment use a modular design. The alarm component 8 can be fixed to the electronic component 6 using screws or similar methods, facilitating the removal of the electronic component 6 for maintenance, replacement, or charging. The electronic component 6 is set inside the lock shell 1, making it difficult to damage and enhancing security. Moreover, both installation and removal of the electronic component 6 can be done without tools, making it convenient and quick.

[0038] It should be noted that: as shown in Figure 14, the lock cylinder 4 in this embodiment can be either a digital lock cylinder 4 or a pin tumbler lock cylinder 4, with no specific limitations. The working principle and method of the second sensor are existing technologies, and this application does not involve any improvements to it.
