The invention relates to a heating defrosting bumper which comprises a bumper body and a millimeter wave radar arranged on the bumper body, a heating module is arranged on the inner side of the bumper body, and the heating module is located in the field angle range of the millimeter wave radar and extends in the antenna direction of the millimeter wave radar. According to the heating and defrosting bumper, the heating module is arranged in the wave-transparent area of the bumper body to heat the bumper body, frosting and fogging on the surface of a millimeter wave radar in the automatic driving process are avoided, and therefore it is ensured that the millimeter wave radar accurately obtains environment data, and the detection distance of the millimeter wave radar is ensured; the trend of the heating wire is set to be consistent with the arrangement direction of the radar antenna, and the distance between the heating wire and the radar antenna is set to be 3.5 mm-6mm which is larger than the wavelength of the millimeter-wave radar, so that the performance loss of the millimeter-wave radar is reduced.
本发明涉及一种加热除霜保险杠,包括保险杠本体和设置在所述保险杠本体上的毫米波雷达,所述保险杠本体内侧设置有加热模块,所述加热模块位于所述毫米波雷达的视场角范围内并沿所述毫米波雷达的天线走向沿伸。本发明的加热除霜保险杠,在保险杠本体的透波区域内设置加热模块对保险杠本体进行加热,避免自动驾驶过程中毫米波雷达表面结霜和结雾,从而确保毫米波雷达准确地获得环境数据,并确保其探测距离;发热丝的走向设置为与雷达天线的排布方向一致,且间距设置为3.5mm‑6mm,大于毫米波雷达的波长,从而降低了毫米波雷达性能损耗。
