[0016] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0017] like Figures 1 to 3 As shown, an explosion-proof radar device of the utility model comprises a box body 10 and a radar 14 arranged in the box body 10, a support plate 12 is arranged in the box body 10, a base of the radar 14 is connected to the support plate 12 by bolts, a cover plate 16 is connected to one side of the box body 10 by bolts, a mounting groove for the end of the radar 14 to pass through is provided on the cover plate 16, a position corresponding to the mounting groove and the radar 14 is coated with glue to increase the sealing performance, and a receiving groove for accommodating a sealing ring 18 is provided on one side of the box body 10 facing the cover plate 16; the end of the radar 14 extends out of the box body 10 to detect the surrounding environment, and most of the circuits and electronic components are located in the box body 10, the box body 10 and the cover plate 16 seal the inside of the box body 10, the sealing ring 18 is used to increase the sealing performance, so that a closed space is formed in the box body 10, when the radar 14 located in the box body 10 is overheated and catches fire, the fire can be extinguished due to insufficient oxygen in the closed box body 10, so as to prevent the flame from continuing to burn and causing damage to the vehicle.
[0018] The bracket 22 also includes a bracket 22, which is provided with a slide groove for the box 10 to slide, and a buffer corresponding to the bottom wall of the box 10 is arranged in the bracket 22 to achieve the buffering effect on the box 10; the bracket 22 is provided with a mounting hole for mounting the bracket 22 on the vehicle, and the bracket 22 serves to connect the vehicle and the box 10. When the vehicle collides or brakes suddenly, the buffer will buffer the box 10 and the radar 14 to reduce damage.
[0019] The buffer member includes a fixed plate 24 arranged in the bracket 22, a spring 32 is arranged on the bracket 22, a mounting plate 26 is movably arranged above the spring 32, connecting plates 28 connected to the box body 10 are arranged on both sides of the mounting plate 26, and a limiting member is arranged between the mounting plate 26 and the fixed plate 24; the buffering effect is achieved by the compression of the spring 32, and the limiting member is arranged between the mounting plate 26 and the fixed plate 24 to limit the maximum distance between the two, so as to prevent the distance between the two from being too large and causing the spring 32 to stretch beyond its maximum stretching limit.
[0020] A through slot is provided at a position of the fixing plate 24 corresponding to the spring 32, and a threaded slot is provided at a position of the mounting plate 26 corresponding to the spring 32. The limiting member includes a mounting bolt 30, and the mounting bolt 30 includes a smooth portion and a threaded portion at the end. The mounting bolt 30 passes through the through slot and the spring 32, and its threaded portion is threadedly connected in the threaded slot; when the car collides or brakes suddenly, the mounting plate 26 moves toward the fixing plate 24, and the spring 32 is compressed to have a buffering effect. When the car accelerates forward, the spring 32 is stretched to have a buffering effect. However, due to the limitation of the mounting bolt 30, the maximum distance between the mounting plate 26 and the fixing plate 24 will not exceed the maximum limit of the spring 32, thereby ensuring that the spring 32 is not easily damaged.
[0021] An introduction device for the cable to pass through is arranged at the bottom of the box body 10. The introduction device includes a connector 34, which penetrates the box body 10 and fits tightly with the box body 10, and has good sealing performance.
[0022] A fire-blocking ring 20 is sleeved on the outer wall of the radar 14, and a groove corresponding to the fire-blocking ring 20 is opened on the side of the cover plate 16 facing the box body 10. The fire-blocking ring 20 is made of metal and is resistant to high temperatures. It can prevent the fire from spreading outside the box body 10, and it has high pressure resistance and can play an explosion-proof role, thereby protecting the vehicle.
