Description

Technical Field

[0001] The utility model relates to the technical field of U-shaped locks, in particular to a U-shaped lock with a tail light. Background Art

[0002] With the aggravation of urban traffic congestion problems and the increasing demand for environmentally friendly travel modes, green means of transportation such as bicycles, electric vehicles and motorcycles have gradually become important choices for people's daily travel. However, the safety problems of these means of transportation have also become prominent. Especially when cycling at night or under low light conditions, due to the lack of sufficient lighting equipment or warning devices, traffic accidents are prone to occur, posing safety hazards to cyclists.

[0003] In order to improve cycling safety, various types of vehicle lights and safety warning devices have emerged on the market. They are used to be installed at the rear of a bicycle to remind the vehicles behind to pay attention to the presence of the cyclist in front and reduce the occurrence of rear-end collisions. At the same time, as an effective anti-theft tool, the U-shaped lock is also widely used in various two-wheeled means of transportation. It prevents the vehicle from being easily moved by locking the frame or the wheel, playing a good anti-theft role.

[0004] Although the existing U-shaped locks already have a certain anti-theft function, and there are many independent tail light products on the market that can provide safety protection for cycling, there is currently a lack of a product that can effectively combine the two functions. Some existing U-shaped locks with alarm functions (such as those shown in the patent with the publication number CN214195910U) have anti-theft functions, but do not consider the safety needs during cycling in actual use. Especially when the vehicle is parked, these U-shaped locks cannot provide additional warning effects; while during cycling, users need to equip a tail light separately, increasing the complexity and cost of use.

Two lock gates 45 are slidably arranged left and right on the upper side of the inner housing 23. A circular turntable 46 is arranged in a matching manner at one end where the two lock gates 45 are close to each other. Two rotating blocks 47 located on the same diameter are provided on the circular turntable 46. The ends of the two lock gates 45 are buckled on the rotating blocks 47. The push rod 43 is connected to one of the lock gates 45. An insertion opening 231 for inserting the two ends of the U-shaped lock rod 1 is provided on the inner housing 23. Lock openings 11 for inserting the lock gates 45 are provided on the inner sides of the two ends of the U-shaped lock rod 1. The above are all well-known means of existing U-shaped locks. In the present utility model, a driving rod 44 is integrally formed at one end of the male row 42 close to the push rod 43. A push button 24 fixedly connected to the driving rod 44 is slidably arranged left and right on the housing 22. After the password on the password wheel 41 is unlocked, directly push the push button 24 to the left, drive the driving rod 44, and then push the male row 42 and the push rod 43, so that the lock gate 45 can be withdrawn from the lock opening 11, and thus the U-shaped lock rod 1 can be pulled out from the insertion opening 231. In addition, in the present utility model, a tail light mounting plate 3 is fixedly connected to one end of the inner housing 23, and a tail light assembly is detachably mounted on the tail light mounting plate 3.

[0038] The tail light assembly specifically includes a tail light housing 51, a tail light cover 52, a circuit board 53, an LED 531, and a micro switch 532. The circuit board 53 is fixedly installed between the tail light housing 51 and the tail light cover 52. The LED 531 and the micro switch 532 are electrically connected to one side of the circuit board 53 facing the tail light cover 52. A tail light button 54 is provided on the tail light cover 52 corresponding to the micro switch 532.

[0039] Further, the micro switch 532 is located in the middle of the circuit board 53, and a plurality of LEDs 531 are provided and surround the micro switch 532. The surrounding arrangement of the plurality of LEDs 531 ensures uniform light distribution and enhances the visual warning effect. The tail light cover 52 is made of a red transparent material. The red transparent tail light cover 52 further improves the visibility of the light and enhances the safety at night or under low light conditions. A button opening 521 corresponding to the micro switch 532 is provided in the middle of the tail light cover 52. The tail light button 54 is installed on the button opening 521. The tail light button 54 is made of rubber material, which has a certain sealing effect on the button opening 521 and is convenient to press.

[0040] Furthermore, a battery 55, a USB charging module 56, and a buzzer 57 are also electrically connected to the circuit board 53. The USB charging module 56 penetrates through the side of the tail lamp housing 51. The USB charging module 56 facilitates users to charge devices at any time. A rubber seal cover 58 for shielding the outside of the USB charging module 56 is provided at the position of the USB charging module 56 on the side of the tail lamp housing 51. The rubber seal cover 58 protects the interface from the external environment and extends the service life. When the present utility model is charging, only the tail lamp assembly needs to be removed for charging, and the other part still functions as a normal U-shaped lock, without the need to take the whole for charging.

[0041] In addition, in the present utility model, a magnetic induction switch 59 facing the inner housing 23 is also electrically connected to the circuit board 53. The inner housing 23 is provided with a magnet moving slot 232 penetrating through the tail lamp mounting plate 3 and corresponding to the magnetic induction switch 59 on the side facing the tail lamp assembly. A magnet seat 6 is movably arranged in the magnet moving slot 232. The magnet seat 6 includes a resisting inclined block 61 penetrating into the socket 231. And a spring 63 for pushing the magnet seat 6 towards the direction of the socket 231 is arranged in the magnet moving slot 232. A magnet 62 is fixedly connected to the side of the magnet seat 6 facing the magnetic induction switch 59. A limiting port 511 for inserting the magnet seat 6 is provided on the tail lamp housing 51. The linkage design of the magnetic induction switch 59 and the magnet 62 enables the tail lamp assembly to intelligently sense the state of the lock rod, thereby realizing the anti-theft alarm function and improving the security of the lock. Further, a resisting inclined block receiving groove 12 is provided at one end of the U-shaped lock rod 1, and there is no resisting inclined block receiving groove 12 at the other end. When the U-shaped lock rod 1 is inserted into the socket 231, if there is no resisting inclined block receiving groove 12 at this end, the U-shaped lock rod 1 will press the resisting inclined block 61, thereby pushing the magnet seat 6 to compress the spring 63 and move towards the magnetic induction switch 59. The magnet seat 6 is inserted into the limiting port 511 of the tail lamp housing 51 to prevent the tail lamp assembly from being rotated and disassembled, and the magnet 62 approaches the magnetic induction switch 59 to trigger the standby state of the alarm circuit. If the end of the U-shaped lock rod 1 inserted into the socket 231 has a resisting inclined block receiving groove 12, the resisting inclined block 61 will not be pressed, and the magnet 62 will not approach the magnetic induction switch 59. Although the lock is locked at this time, the alarm circuit will not be triggered. This structure provides a flexible usage scenario.

[0042] The specific structure of the taillight assembly installed on the taillight mounting plate 3 is that four L-shaped buckles 31 are integrally formed on the taillight mounting plate 3. The four L-shaped buckles 31 are all arc-shaped structures and are located on the same center of a circle. An entry through-hole 512 for the L-shaped buckle 31 to insert is formed on the taillight housing 51. The number of the entry through-holes 512 corresponds to that of the L-shaped buckles 31, and a buckle turning bayonet 513 is formed on one side of each entry through-hole 512 on the taillight housing 51. During installation, first make the L-shaped buckle 31 enter the entry through-hole 512 of the taillight housing 51, and then rotate the taillight assembly to make the L-shaped buckle 31 enter the buckle turning bayonet 513, thus completing the fixation. When disassembling, when the U-shaped lock rod 1 leaves the socket 231 or the end of the U-shaped lock rod 1 with the abutting inclined block receiving groove 12 is located in the socket 231, and at this time the magnet block seat 6 is not inserted into the limit port 511 of the taillight housing 51, the taillight assembly can be rotated. Rotate the taillight assembly in the reverse direction to make the L-shaped buckle 31 exit the buckle turning bayonet 513 and return to the entry through-hole 512, so that the taillight assembly can be removed.

[0043] Furthermore, a deformable plate 32 is integrally formed on the taillight mounting plate 3. A positioning block 33 is integrally formed on the deformable plate 32. A positioning groove 514 for the positioning block 33 to fit into is provided on the taillight housing 51. The design of the deformable plate 32 and the positioning block 33 ensures the accurate positioning of the taillight assembly and improves the accuracy and stability of installation.

[0044] In the present utility model, a push seat 7 and a push spring 71 for pushing the push seat 7 towards the direction of the U-shaped lock rod 1 are provided in the socket 231. The design of the push seat 7 and the push spring 71 enables the U-shaped lock rod 1 to automatically pop out after unlocking, simplifies the unlocking operation, and improves the convenience and smoothness of use.

[0045] In the present utility model, when the tail light assembly is installed on the tail light mounting plate 3, when the U-shaped lock rod 1 is inserted into the socket 231 for locking, if the vehicle is subjected to abnormal vibration or attempts to unlock illegally, the buzzer 57 will emit a sound warning, and at the same time the LED 531 will also flash to provide a visual warning. When one end of the U-shaped lock rod 1 having the abutting inclined block receiving groove 12 is inserted into the socket 231, the abutting inclined block 61 will not be pressed, and the magnet 62 will not approach the magnetic induction switch 59. At this time, although it is locked, the alarm circuit will not be triggered. It should be noted that the functions of the circuit board 53, the battery 55, the LED 531, the microswitch 532, the buzzer 57, the USB charging module, and the magnetic induction switch 59 are supported by a large number of mature technologies. The essence of the present utility model lies in optimizing the combination of existing hardware and its connection method for a specific application scenario to adapt to the function that the tail light assembly can flash during anti-theft to improve the anti-theft performance and be used as a tail light during riding. This application does not make improvements to the alarm circuit either, and its working principle and alarm trigger mechanism are the same as those of the prior art, which are common knowledge to those skilled in the art.

[0046] During riding, the tail light assembly is removed from the tail light mounting plate 3 and installed at the back of the bicycle as a tail light. Press the tail light button 54, and the tail light will flash. Press it again to stop flashing. It should be noted that during use, a tail light mounting bracket with the same structure as the tail light mounting plate 3 needs to be fixedly installed at the back of the bicycle for the tail light assembly to be installed on the back of the bicycle.

[0047] At the same time, it should be pointed out that the terms used in the present utility model, such as: "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection scope of the present utility model.

[0048] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
