[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figures 1-4 The utility model provides a new energy vehicle charging gun circuit board, including a circuit board body 1, a mounting bracket 2 is provided on the outside of the circuit board body 1, and the mounting bracket 2 is provided inside the charging gun body. The surface of the circuit board body 1 is slidably connected to the inner wall of the mounting bracket 2, and a cover plate 3 connected to the charging gun body is provided above the mounting bracket 2. The cover plate 3 is detachable, and mounting holes 14 are provided at the four corners of the top of the cover plate 3. The top of the mounting hole 14 is provided with a countersunk hole 15, and the four corners of the bottom of the cover plate 3 are provided with a tightening rod 4, and the bottom end of the tightening rod 4 is in contact with the top of the circuit board body 1.
[0022] In this embodiment, the cover plate 3 is installed on the surface of the charging gun body, and the mounting frame 2 is arranged inside the charging gun body. The surface of the cover plate 3 is provided with a mounting hole 14, and the cover plate 3 can be fixed to the surface of the charging gun body by passing a bolt through the mounting hole 14. When the bolt is tightened, the top of the bolt will be hidden in the inner cavity of the countersunk hole 15 to ensure the flatness of the surface of the charging gun. When installing the cover plate 3, the cover plate 3 moves downward and will push the circuit board body 1 downward through the tightening rod 4, so that the circuit board body 1 is tightly fixed to the inner cavity of the mounting frame 2.
[0023] Preferably, an elastic support assembly for supporting the circuit board body 1 is installed at the bottom of the mounting frame 2, and the elastic support assembly includes a fixed tube 5 fixedly installed at the four corners of the bottom of the mounting frame 2, and the inner cavity of the fixed tube 5 is slidably connected to a slide plate 6, and a connecting rod 7 is fixedly installed on the top of the slide plate 6. The top of the connecting rod 7 passes through the fixed tube 5 and the mounting frame 2 in sequence and extends to the inner cavity of the mounting frame 2 where a support plate 8 is fixedly installed. The bottom of the circuit board body 1 is fitted with the top of the support plate 8, and a tension spring 9 is fixedly installed on the top of the slide plate 6 and located outside the connecting rod 7. The top of the tension spring 9 is fixedly connected to the inner wall of the fixed tube 5. Through holes 18 are opened at the four corners of the bottom of the mounting frame 2, and the surface of the connecting rod 7 is slidably connected to the inner wall of the through hole 18.
[0024] By configuring the elastic support assembly, when installing the circuit board body 1, the downward movement of the circuit board body 1 pushes against the support plate 8. The movement of the support plate 8 drives the slide plate 6 via the connecting rod 7. The movement of the slide plate 6 pulls the tension spring 9. When the cover plate 3 is removed, the reaction force generated by the tension of the tension spring 9 pushes the support plate 8 upward, pushing the circuit board body 1 out of the mounting frame 2, making it easier for the user to remove the circuit board body 1 for inspection. The provision of the through hole 18 provides space for the connecting rod 7 to move, allowing the connecting rod 7 to pass through the through hole 18 and penetrate the bottom of the mounting frame 2.
[0025] Among them, a limiting component is arranged between the surface of the slide plate 6 and the inner wall of the fixed tube 5. The limiting component includes a limiting rod 10 fixedly installed on both sides of the inner cavity of the fixed tube 5. Both sides of the slide plate 6 are provided with a limiting groove 11 adapted to the limiting rod 10. The surface of the limiting rod 10 is slidably connected to the inner wall of the limiting groove 11. Through the setting of the limiting component, the sliding stability of the slide plate 6 in the inner cavity of the fixed tube 5 can be improved, and the slide plate 6 can be limited. When the slide plate 6 moves, it will drive the limiting groove 11 on its surface to slide on the surface of the limiting rod 10.
[0026] It is worth noting that a sliding assembly is provided between the surface of the support plate 8 and the inner wall of the mounting frame 2. The sliding assembly includes a slider 12 fixedly mounted on the surface of the support plate 8. A sliding groove 13 is provided on the inner wall of the mounting frame 2 at a position corresponding to the slider 12. The surface of the slider 12 is slidingly connected to the inner wall of the sliding groove 13. By setting the sliding assembly, the stability of the movement of the support plate 8 can be improved. When the support plate 8 moves, it will drive the slider 12 on its surface to slide in the inner cavity of the sliding groove 13.
[0027] Furthermore, a heat dissipation groove 16 is provided on the surface of the support plate 8, and a through groove 17 is provided on the surface and bottom of the mounting frame 2. By using the heat dissipation groove 16 and the through groove 17 at the bottom of the mounting frame 2 in combination, the circuit board body 1 can be easily dissipated, and the through grooves 17 around the mounting frame 2 can easily allow the user to connect the wiring harness inside the charging gun with the circuit board body 1.
[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
