Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] Example:

[0033] like Figures 1 to 8 As shown, the present invention discloses a disc brake lock with a taillight, comprising a lock body base 1 and a lock body cover 2 that overlap each other. The lock body base 1 and the lock body cover 2 are fixed by screws. A lock cylinder mounting sleeve 11 is integrally formed on the lock body base 1, and a lock cylinder assembly is disposed within the lock cylinder mounting sleeve 11. The lock body cover 2 is provided with a lock cylinder opening 21 for exposing the upper end of the lock cylinder assembly. In addition, a main circuit board 31 and a battery 32 electrically connected to the main circuit board 31 are disposed between the lock body base 1 and the lock body cover 2. In the present invention, a taillight mounting groove 22 is provided on the lock body cover 2 on a side thereof away from the lock cylinder assembly. A taillight assembly is mounted within the taillight mounting groove 22, and the taillight assembly is electrically connected to the main circuit board 31. This application combines a traditional disc brake lock with a taillight function, which not only improves the anti-theft performance of the vehicle when parked, but can also be used as a taillight during riding, providing an additional warning function and enhancing riding safety.

[0034] Specifically, the taillight assembly includes a taillight circuit board 41, a taillight base shell 44 and a taillight upper shell 46. The taillight upper shell 46 is fixedly covered on the taillight base shell 44, specifically by gluing, and the taillight circuit board 41 is fixedly arranged between the taillight upper shell 46 and the taillight base shell 44. The taillight circuit board 41 is electrically connected to the main circuit board 31, wherein the side of the taillight circuit board 41 facing the taillight upper shell 46 is provided with a micro switch 42 and a taillight LED 43, and a taillight button 47 is provided on the taillight upper shell 46 corresponding to the micro switch 42. Through the design of the micro switch 42 and the taillight button 47, the user can conveniently control the on / off state of the taillight, thereby increasing the convenience and flexibility of use.

[0035] Furthermore, the micro switch 42 is located in the middle of the taillight circuit board 41, and a plurality of taillight LEDs 43 are provided and surround the outside of the micro switch 42, ensuring that the brightness of the taillight is uniform and the coverage is wide. The taillight upper shell 46 is made of red transparent material, which further enhances the penetration and visibility of the light and improves the warning effect at night or in low light conditions. A button port 461 corresponding to the micro switch 42 is opened in the middle of the taillight upper shell 46, and the taillight button 47 is installed on the button port 461. The taillight button 47 is made of rubber material, has a certain sealing effect on the button port 461 and is easy to press.

[0036] The specific structure of the taillight assembly fixed in the taillight mounting groove 22 is: a connecting hole 441 is opened on the taillight base shell 44, and an internal threaded sleeve 45 is interference fit in the connecting hole 441, and a screw through-hole 23 corresponding to the internal threaded sleeve 45 is opened in the taillight mounting groove 22 of the lock body upper cover 2, which can be fixed later by screws.

[0037] In the present invention, the main circuit board 31 is also electrically connected to a magnetic induction switch 33 facing the lock core assembly, and the lock core assembly is provided with a magnet 57 on one side of the magnetic induction switch 33 .

[0038] In addition, an alarm speaker 34 and a USB charging module 35 are electrically connected to the main circuit board 31. The USB charging module 35 passes through one side of the lock body cover 2. The USB charging module 35 is used to charge the battery 32. At the same time, a rubber sealing cover 7 for shielding the outside of the USB charging module 35 is provided on the outside of the lock body cover 2 at the position of the USB charging module 35. The rubber sealing cover 7 protects the interface of the USB charging module 35 from being affected by the external environment.

[0039] In the present invention, the lock core assembly specifically includes a lock core 51 and a lock core sleeve 52, a magnet 57 is fixed on the lock core sleeve 52, and a magnet groove 111 is opened on the side of the lock core mounting sleeve 11 facing the magnetic induction switch 33, the magnet 57 slides up and down and fits in the magnet groove 111, a limiting step 511 for clamping the lock core sleeve 52 is provided at the upper position of the lock core 51, and a limiting plate 512 is provided at the lower side of the lock core 51, the limiting step 511 and the limiting plate 512 do not limit the rotation of the lock core 51 relative to the lock core sleeve 52 after unlocking, but limit The positioning step 511 and the limit plate 512 will cause the lock core 51 and the lock core sleeve 52 to move up and down synchronously. A spring 53 is provided between the bottom of the lock core mounting sleeve 11 and the lock core sleeve 52. The lower end of the lock core 51 is fixedly connected to a lock rod 54. A lock hole 55 is provided on the side of the lock rod 54. A locking block 61 for inserting the lock hole 55 and a locking spring 62 for pushing the locking block 61 toward the lock rod 54 are provided on the lock body base 1. The lock core 51 can only rotate relative to the lock core sleeve 52 when the corresponding key is inserted. This is common knowledge among technicians in this field.

[0040] Furthermore, in order to enable the lock core sleeve 52 to slide up and down stably, a limiting groove 112 is provided on the side of the lock core sleeve 52 away from the magnet groove 111, and a limiting block 56 located in the limiting groove 112 is fixedly connected to the lock core sleeve 52. In addition, in order to limit the position of the lock core assembly when it moves upward, an upper cover sleeve 12 is provided on the upper fixed cover of the lock core mounting sleeve 11, which can be specifically bonded by glue. The upper cover sleeve 12 limits the upward movement range of the magnet 57 and the limiting block 56.

[0041] When the present invention is in the unlocked state, that is, the locking block 61 is not in the lock opening 55 on the lock rod 54, the spring 53 pushes the lock cylinder sleeve 52 upward, so that the lock cylinder sleeve 52, the lock cylinder 51 and the lock rod 54 all move upward, and the lock rod 54 exits the receiving groove 13. At this time, it is in the unlocked state, the magnet 57 is away from the magnetic induction switch 33, and the alarm circuit is closed;

[0042] When locking, the lock cylinder 51 is pressed downward and the lock is turned with the key, so that the lock hole 55 on the lock rod 54 faces the lock block 61. When the lock spring 62 pushes the lock block 61 into the lock hole 55 on the lock rod 54, the spring 53 can no longer push the lock cylinder sleeve 52 upward, and the lock state is now locked. At this time, the magnet 57 approaches the magnetic induction switch 33, triggering the alarm circuit to enter the standby state; if the vehicle is subjected to abnormal vibration or an attempt is made to illegally unlock the vehicle, the alarm horn 34 will sound an audible warning, and the taillight assembly will flash to provide a visual warning;

[0043] During normal unlocking, the key is inserted into the lock cylinder 51 and rotated, so that the lock port 55 on the lock rod 54 rotates to the back of the lock block 61. At this time, the lock block 61 is pushed out of the lock port 55, so the spring 53 pushes the lock cylinder sleeve 52 upward, thereby causing the lock cylinder sleeve 52, the lock cylinder 51 and the lock rod 54 to move upward, and the magnet 57 moves away from the magnetic induction switch 33, and the alarm circuit is closed.

[0044] The present invention also has a locked state without the need for an alarm. When the key is inserted into the lock cylinder 51 and the lock cylinder 51 is fully pressed into the lock cylinder mounting sleeve 11, the magnetic induction switch 33 first detects the magnet 57 and sends a signal. The lock cylinder 51 is then released, causing it to spring back up. The lock cylinder 51 is then fully pressed into the lock cylinder mounting sleeve 11 again. The key is then turned, causing the lock opening 55 on the lock rod 54 to rotate to the locking block 61, locking the lock by the locking block 61. The magnetic induction switch 33 then detects the magnet 57 and sends a signal. The main circuit board 31 then determines that the lock is normal and does not require an alarm. The alarm is then turned off. At this point, the present invention will not trigger an alarm even if it is lightly tapped or swung externally. This operating mode is already disclosed in a disc brake lock with an alarm device, currently available in Patent No. CN217681120U. It should be noted that in this state, pressing the taillight button 47 on the taillight assembly causes the taillight LED 43 to flash; pressing it again turns it off. It should be noted that the hardware in the present invention: main circuit board 31, battery 32, taillight circuit board 41, taillight LED 43, micro switch 42, alarm horn 34, USB charging module 35, the functions to be achieved are supported by a large number of mature technologies. The essence of the present invention is to optimize the combination of existing hardware and its connection method for specific application scenarios, so as to adapt the taillight assembly to flash during anti-theft to improve anti-theft performance and be used as a taillight when riding. This application also does not make any improvements to the alarm circuit. Its working principle and alarm triggering mechanism are the same as the existing technology, which is common knowledge for those skilled in the art.

[0045] It is also necessary to explain that Figure 9 and Figure 10 As shown: In actual application, in order to ensure the stability of the present invention at the rear of a vehicle, a dedicated bracket 8 must be installed at the rear of the vehicle. The figures in this embodiment illustrate only one type of dedicated bracket. The dedicated bracket can also be of other shapes suitable for this application and is not limited here. The dedicated bracket 8 is used to insert into the groove 13 on the lock body base 1 to cooperate therewith. The dedicated bracket 8 has a socket 81 for inserting the locking rod 54. In this way, the present invention can be installed on the dedicated bracket 8 and used as a taillight when the vehicle is locked but no alarm is required.

[0046] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
