Abstract

The invention provides a vehicle body height sensor. The vehicle body height sensor comprises a shell and a rotor, wherein a Hall chip and a bearing are arranged in the shell; the rotor comprises a rotating shaft, a swing arm and a magnetic ring; the swing arm is connected with the rotating shaft and is connected with a vehicle body; the magnetic ring is placed on the rotating shaft; the rotating shaft penetrates in the bearing; a torsional spring which keeps the posture of the swing arm sleeves the rotating shaft; one end of the torsional spring is fixed on the rotor; and the other end of the torsional spring is fixed on the shell. The torsional spring is arranged in the shell, the normal posture of the swing arm can be always kept through the torsional spring, the posture of the swing arm includes the position and the direction of the swing arm in space, even if the swing arm is impacted and the posture of the swing arm is changed when the vehicle body height sensor is mounted, the swing arm can be reset to be in the original state through the torsional spring, the reliability of the using performance of the vehicle body height sensor can be ensured after the vehicle body height sensor is mounted, and the vehicle body height sensor has high vibration resistance.

Description

technical field [0001] The invention relates to the related technical field of automobile electronic technology, in particular to a vehicle body height sensor. Background technique [0002] As the information source of the automotive electronic control system, the automotive sensor is a key component of the automotive electronic control system and one of the core contents of the research in the field of automotive electronic technology. Automotive sensors perform real-time and accurate measurement and control of various information such as temperature, pressure, position, altitude, acceleration, and vibration. The key to measuring the control system level of modern high-end cars lies in the quantity and level of its sensors. However, the highest level of automotive sensor products in China is more than 10 years behind similar foreign products, and more than 500,000 sets of high-performance automotive sensors are imported every year. Vehicle body height sensor is still a new...
