Millimeter wave radar oil quantity detection device applied to oil tank

The utility model relates to a millimeter wave radar oil mass detection device applied to an oil tank, which comprises a cylinder body with a low dielectric constant, a radar transceiver arranged at the top end in the cylinder body, and a side hole formed in the side surface of the upper end of the cylinder body, the air floatation reflection structure comprises an annular air floatation part and a cylindrical air floatation part which are nested with each other and are in sliding connection. According to the utility model, the double air floaters and the damping structure are matched with the locking structure to cope with the instantaneous change of the liquid level of the oil tank in the driving process of an automobile, so that the instantaneous change of the liquid level in the acceleration and deceleration process does not influence the detection of the actual height of the liquid level by the radar transceiver; and the monitoring of the oil quantity is more accurate. 本实用新型涉及一种应用于油箱的毫米波雷达油量检测装置，包括低介电常数的
