Technical Field

[0001] This application relates to the field of automotive LED lighting technology, and in particular to a leakage-proof automotive LED lighting circuit board. Background Technology

[0002] With the booming development of the automotive industry, automotive LED lights, with their significant advantages such as high brightness, low energy consumption, and long lifespan, are widely used in automotive lighting systems, such as headlights, taillights, and brake lights. However, existing automotive LED light circuit boards have revealed many problems in actual use, the most prominent of which is the inconvenience of disassembly and assembly.

[0003] The existing connection methods on circuit boards are not reasonable. Traditional connection methods mostly use screw fastening or soldering. Screw fastening is prone to stripping after repeated disassembly and assembly, resulting in loose connections and affecting the stability of the circuit. Soldering requires professional tools and skills, and can easily damage components on the circuit board during disassembly, causing great inconvenience for repair and replacement. Therefore, a leakage-proof automotive LED light circuit board is proposed to solve the above problems. Utility Model Content

The ends of the guide rails away from the fixing blocks are fixedly connected to fixing plates. The outer walls of the fixing blocks are fixedly connected to traction rods. The ends of the traction rods away from the fixing blocks pass through the fixing plates. The outer walls of the traction rods are fitted with springs, which are located between the fixing blocks and the fixing plates.

[0008] Preferably, the disassembly and assembly mechanism further includes a pressure rod slidably connected to the outer wall of the mounting plate via two bearing seats, and a connecting rod rotatably connected to the end of a plurality of traction rods away from the fixed block, wherein the end of the connecting rod away from the traction rod is hinged to the outer wall of the pressure rod.

[0009] Preferably, a limiting block is fixedly connected to the end of the guide rail away from the fixed plate, and the limiting block is in contact with the fixed block.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a leakage-proof automotive LED light circuit board. (See also...) Figure 1-4A leakage-proof automotive LED light circuit board includes a mounting plate 1 and a circuit board body 2. The circuit board body 2 is mounted on the outer wall of the mounting plate 1. The outer wall of the mounting plate 1 has multiple positioning holes 3. The outer wall of the circuit board body 2 is fixedly connected to multiple positioning posts 4. The positioning posts 4 are adapted to the positioning holes 3 and inserted into each other. The outer wall of the mounting plate 1 is equipped with a disassembly and assembly mechanism.

[0022] The disassembly and assembly mechanism includes multiple guide rails 8 fixedly connected to the outer wall of the mounting plate 1. The inner walls of the multiple guide rails 8 are slidably connected to locking blocks 9. The outer walls of the locking blocks 9 are fixedly connected to fixing blocks 10. The end of the guide rail 8 away from the fixing blocks 10 is fixedly connected to a fixing plate 11. The outer wall of the fixing blocks 10 is fixedly connected to a traction rod 12. The end of the traction rod 12 away from the fixing blocks 10 passes through the fixing plate 11. The outer wall of the traction rod 12 is sleeved with a spring 13, which is located between the fixing blocks 10 and the fixing plate 11.

[0023] The disassembly and assembly mechanism also includes a pressure rod 16 that is slidably connected to the outer wall of the mounting plate 1 via two bearings 15, and a connecting rod 17 that is rotatably connected to the end of a plurality of traction rods 12 away from the fixed block 10. The end of the connecting rod 17 away from the traction rod 12 is hinged to the outer wall of the pressure rod 16.

[0024] The end of the guide rail 8 away from the fixed plate 11 is fixedly connected to the limiting block 14, and the limiting block 14 is in contact with the fixed block 10.

[0025] The outer walls of multiple positioning posts 4 are provided with slots 5, and the end of the block 9 away from the fixing plate 11 is adapted to and engaged with the slot 5.

[0026] The outer wall of the mounting plate 1 is fixedly connected with multiple fixing feet 6. The outer wall of the fixing feet 6 has two fixing holes 7. The multiple fixing feet 6 are evenly distributed at the four corner edges of the mounting plate 1.

[0027] The implementation principle of the leakage-proof automotive LED light circuit board of this application embodiment is as follows: During installation, multiple positioning holes 3 on the outer wall of the circuit board body 2 are inserted into multiple positioning holes 3 on the outer wall of the mounting plate 1. When multiple positioning pins 4 enter multiple positioning holes 3, the disassembly and assembly mechanism is automatically triggered. At this time, the outer wall of the positioning hole 3 abuts against the inclined surface of the end of the locking block 9, and the multiple locking blocks 9 can be easily pushed inward. At this time, the locking block 9 drives the fixing block 10 to move. The fixing block 10 and the fixing plate 11 cooperate to compress the spring 13. The spring 13 deforms to generate elastic force. When the positioning pin 4 is fully inserted into the positioning hole 3, the mounting plate 1 and the circuit board body 2 are tightly attached, and the positioning pin 4 cannot move. The slot 5 on the outer wall of the positioning pin 4 corresponds to the end of the locking block 9. At this time, the fixing block 10 is reset under the elastic force of the spring 13. The fixing block 10 then drives the end of the locking block 9 to engage in the slot 5, thereby locking the multiple positioning pins 4 in the positioning hole 3 and completing the quick installation of the circuit board body 2.

[0028] When it is necessary to disassemble the circuit board body 2, press down the pressure rod 16. The pressure rod 16 slides downward within the two bearing seats 15. At this time, the pressure rod 16 pulls multiple connecting rods 17 downward to rotate. The other end of the multiple connecting rods 17 pulls multiple traction rods 12 to move in the direction of the pressure rod 16. The traction rods 12 slide within the fixing plate 11, and then pull multiple locking blocks 9 to retract inward within the guide rail 8 through the fixing block 10. At this time, the ends of the multiple locking blocks 9 disengage from the multiple locking slots 5, which can quickly release the locking of the multiple positioning posts 4. The circuit board body 2 can then be easily disassembled from the mounting plate 1. Disassembly is convenient and quick, and it is not easy to damage the components on the circuit board.
