Due to the fact that the working condition and the working condition of the vehicle are complex in the using process, the vehicle can often experience various extremely severe environments such as wind, frost, rain, snow, sand and the like, and can cause damage to various sensors. Therefore, for high-precision devices such as millimeter wave radars, the protection level of IP67 or even higher level is generally required to be achieved, and the requirement of repeated disassembly and assembly for inspection and maintenance is also required to be met, so that a sealing structure capable of being repeatedly disassembled and assembled is required to be adopted.
Due to the thin-wall structure of the radome, a groove is difficult to install a sealing element on the radome body or the rear cover of the radome body; if the gasket is arranged on the end surface of the back cover, the heat dissipation or the static electricity discharge is not facilitated. In the prior art, the radome sealing structure is generally sealed by preparing an annular sealing element, expanding and installing the annular sealing element on the front end of the outer peripheral surface of the rear cover and then installing the annular sealing element in interference fit with the radome body. Because the annular sealing member can be stretched after being unfolded, the cross section is deformed, and the interference with the radome body is difficult to control. Meanwhile, due to the fact that the sealing elements are assembled on the two sides in an interference mode, the sealing elements are prone to toppling and overturning in the installation process of the radome rear cover and the radome body, the assembly efficiency is influenced, and the sealing reliability of a product is seriously influenced.
