[0022] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As Figures 1-5 shown, the present utility model provides a flexible circuit board for a new energy vehicle headlight, including two sets of symmetric rotating shafts 13. The outer surfaces of the two sets of rotating shafts 13 are both rotatably connected with two first rotating seats 11. The top ends of the first rotating seats 11 are fixedly connected with a top cover 2. The outer surfaces of the two sets of rotating shafts 13 are both rotatably connected with two second rotating seats 12. The top ends of the second rotating seats 12 are fixedly connected with a bottom cover 3. The top cover 2 and the bottom cover 3 cooperate to form a protective housing. The outer surface of the top cover 2 is symmetrically and fixedly connected with two buckles 21. The outer surface of the bottom cover 3 is symmetrically and fixedly connected with two blocks 31. The two buckles 21 and the two blocks 31 are in snap connection. The outer surface of the rotating shaft 13 is fixedly connected with a connecting column 4. The bottom of the connecting column 4 is fixedly connected with a bottom plate 41. The top of the connecting column 4 is symmetrically provided with two movable grooves 5. A limiting column 51 is movably connected between the inner walls of the two movable grooves 5. The outer surfaces of the two limiting columns 51 movably penetrate the outer surface of the bottom plate 41. A top plate 42 is fixedly connected between the tops of the two limiting columns 51. Rubber pads 44 are fixedly connected to the bottom of the top plate 42 and the top of the bottom plate 41. A second fastening bolt 43 is installed on the top of the top plate 42. The outer surface of the second fastening bolt 43 penetrates the top plate 42 and its end is threadedly connected with the connecting column 4. The outer surfaces of the two rubber pads 44 are in contact with the outer surface of the circuit board body 1. The tops of the two rotating shafts 13 are both fixedly connected with a first fastening bolt 22.

[0025] The effect achieved by the entire Embodiment 1 is as follows: When in use, first install the flexible circuit board body 1 on the outer surfaces of the two rubber pads 44. The rubber pads 44 have good elasticity and buffering performance, and can absorb and disperse the vibration and impact from inside the headlight, thereby protecting the circuit board body 1 from damage. Then, fix the rubber pads 44 with the installed circuit board body 1 on the top and bottom of the top plate 42 and the bottom plate 41 respectively. The top plate 42 and the bottom plate 41 are movably connected to the connecting column 4 through the limit posts 51 to form an adjustable clamping mechanism. Then, rotate the second fastening bolt 43. Under the action of the second fastening bolt 43, the top plate 42 will move downward. At this time, the two limit posts 51 at the bottom of the top plate 42 will move downward correspondingly inside the moving slots 5, so that the distance between the top plate 42 and the bottom plate 41 can be adjusted, and the pressing degree of the rubber pads 44 on the circuit board body 1 can be effectively controlled. When it is necessary to install or maintain the circuit board body 1, first, the locking state between the top cover 2 and the bottom cover 3 needs to be released, which is achieved by pulling up the top cover 2 so that the buckle 21 on the top cover 2 disengages from the block 31 on the bottom cover 3. Subsequently, under the action of the rotating shaft 13, rotate the top cover 2 upward and rotate the bottom cover 3 downward simultaneously, so that the included angle between the two gradually increases until the protective housing is completely opened. At this time, the user can easily install the circuit board body 1 and the access of other circuits. When the protective housing is in the open state, if it needs to be temporarily fixed for other operations, it can be achieved by rotating the first fastening bolt 22. The first fastening bolt 22 firmly fixes the first rotating seat 11 and the second rotating seat 12, so that the top cover 2 and the bottom cover 3 remain stable while maintaining a certain included angle. This design not only facilitates the operation of the user, but also improves the further protection of both sides of the circuit board body 1 during use. Through the innovative design of the protective housing and the adjustable clamping mechanism, this design effectively isolates the humid environment, dust accumulation, and direct contact with external conductors, thereby greatly reducing the short - circuit risk caused by the exposure of the conductive circuits on both sides of the circuit board. This improvement not only extends the service life of the circuit board, but also ensures the stability and reliability of the new - energy vehicle headlight.

[0026] Embodiment 2: As Figures 1-5 shown, the top ends of the two rotating shafts 13 are fixedly connected with first fastening bolts 22.

[0027] The effect achieved by the entire Embodiment 2 is that the first fastening bolt 22 is used to fix the state of the top cover 2 and the bottom cover 3 after they are opened, ensuring that they will not shake after being opened, so as not to affect the overall use.

[0028] Working principle: When in use, first install the flexible circuit board body 1 on the outer surfaces of two rubber pads 44, and then fix the rubber pads 44 with the installed circuit board body 1 on the top and bottom of the top plate 42 and the bottom plate 41 respectively. The top plate 42 and the bottom plate 41 are movably connected to the connecting column 4 through the limiting columns 51 to form an adjustable clamping mechanism. Then, rotate the second fastening bolt 43, and the top plate 42 will move downward. At this time, the two limiting columns 51 at the bottom of the top plate 42 will move downward correspondingly inside the moving groove 5, so that the distance between the top plate 42 and the bottom plate 41 can be adjusted, and the pressing degree of the rubber pad 44 on the circuit board body 1 can be effectively controlled. When it is necessary to install or maintain the circuit board body 1, first, the locking state between the top cover 2 and the bottom cover 3 needs to be released, which is achieved by pulling the top cover 2 upward so that the buckle 21 disengages from the latch 31. Subsequently, rotate the top cover 2 upward and rotate the bottom cover 3 downward at the same time, so that the included angle between the two gradually increases until the protective housing is completely opened. At this time, the user can easily install the circuit board body 1 and the access of other circuits. When the protective housing is in the open state, if it needs to be temporarily fixed for other operations, it can be achieved by rotating the first fastening bolt 22. The first fastening bolt 22 firmly fixes the first rotating seat 11 and the second rotating seat 12, so that the top cover 2 and the bottom cover 3 remain stable while maintaining a certain included angle. This design not only facilitates the operation of the user, but also improves the further protection of both sides of the circuit board body 1 during use. Through the innovative design of the protective housing and the adjustable clamping mechanism, it effectively isolates the humid environment, dust accumulation, and direct contact with external conductors, thus greatly reducing the short-circuit risk caused by the exposure of the conductive circuits on both sides of the circuit board. This improvement not only extends the service life of the circuit board, but also ensures the stability and reliability of the new energy vehicle headlight. And, the first fastening bolt 22 is used to fix the state after the top cover 2 and the bottom cover 3 are opened to ensure that they will not shake after being opened, thus affecting the overall use.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical solution content of the present invention is not departed from, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
