Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-5This utility model provides a technical solution: an anti-interference shielding device for RSU equipment, comprising an anti-interference shielding device body 1 and an RSU equipment 2. The anti-interference shielding device body 1 is disposed on the RSU equipment 2. The anti-interference shielding device body 1 is provided with a rear protective plate 8, which has a bent structure and engages with the RSU equipment 2 to ensure a stable connection between the rear protective plate 8 and the RSU equipment 2. The RSU equipment 2 is provided with a sealing and snap-fitting front end cover 3 and a rear shell 5. The back of the rear shell 5 is also integrally provided with at least four mounting holes 10, and the mounting holes 10 and the heat dissipation fins 7 are also integrally structured. This structure allows the RSU equipment 2 to be installed through the mounting holes 10. The mounting hole 10 protrudes outwards to ensure more stable bolt fixing. A gap difference is formed between the mounting hole 10 and the heat dissipation fin 7, allowing sufficient space for heat dissipation. The rear protective plate 8 is recessed inwards at the corresponding part of the mounting hole 10, and a mounting pad 9 is provided in the recessed part of the rear protective plate 8. Both the mounting pad 9 and the rear protective plate 8 have through holes corresponding to the positions of the mounting hole 10. This structure makes the rear protective plate 8 more stable when bent. The rear protective plate 8, in conjunction with the mounting pad 9, ensures reliable installation of the RSU device 2, making the structure of the anti-interference shielding device main body 1 reliable. Furthermore, an integrated circuit board 4 is installed inside the rear shell 5, and the integrated circuit board 4 integrates… An interface base 11 is installed. The upper and lower ends of the rear protective plate 8 are respectively provided with grooves, and an upper fastening plate 6 and a lower fastening plate 12 are respectively engaged in the grooves of the rear protective plate 8. Through holes corresponding to the positions of the interface base 11 are respectively provided between the rear protective plate 8 and the upper and lower fastening plates 6 and 12. Both the upper and lower fastening plates 6 and 12 are L-shaped structures and are respectively fastened to the rear protective plate 8 with screws. This structure allows the upper and lower fastening plates 6 and 12 to be inserted and fixed to the interface base 11 at the upper and lower ends, thus stabilizing the fixing structure and preventing loosening of the interface base 11 fixing parts, ensuring anti-interference shielding performance. The two sides between the rear protective plate 8 and the rear shell 5... The structure is designed to allow heat dissipation through the gap between the rear protective plate 8 and the heat dissipation fin 7, preventing high temperatures from affecting the anti-interference shielding performance of the RSU device 2. The rear shell 5 is integrally provided with a partition fin 13 and a heat dissipation fin 7 on its inner and outer sides, respectively. The heat dissipation fin 7 is located in the inner area of the rear protective plate 8, and the partition fin 13 is located between the modules integrated on the integrated circuit board 4. The partition fin 13 is coated with a shielding layer 14. This structure can separate the modules integrated on the integrated circuit board 4 through the partition fin 13, reducing mutual interference between modules. The shielding layer 14 can be made of aluminum oxide, which has thermally conductive but non-conductive properties to avoid affecting heat dissipation.
[0020] Working principle: When using this anti-interference shielding device for RSU equipment, the RSU equipment 2 first undergoes efficient anti-interference shielding treatment through the main body 1 of the anti-interference shielding device. The front cover 3 and rear shell 5 provide fully enclosed anti-interference shielding. Inside the rear shell 5, partition ribs 13 coated with a shielding layer 14 separate the modules on the integrated circuit board 4, ensuring that the modules do not interfere with each other. Heat dissipation ribs 7 are used for heat dissipation of the RSU equipment 2 and the main body 1 of the anti-interference shielding device, preventing high temperatures from affecting the anti-interference shielding performance. The rear protective plate 8 is attached to the RSU equipment 2. The RSU device 2 is mounted on the fixed rod via the mounting pad 9, the rear protective plate 8, and the mounting hole seat 10. The gap between the rear protective plate 8 and the heat dissipation fin 7 allows the heat dissipation fin 7 to dissipate heat. At the same time, the rear protective plate 8 covers the heat dissipation fin 7, reducing the dust adhering to the heat dissipation fin 7. The structure fixed on the interface seat 11 is secured by the cooperation of the rear protective plate 8 with the upper fastening plate 6 and the lower fastening plate 12, ensuring the stability of the fixed structure on the interface seat 11, thereby ensuring the anti-interference shielding performance and making the use of the RSU device 2 more reliable, thus completing a series of tasks.
