Abstract

A vehicle chassis height sensor relates to a vehicle chassis height detecting device which is characterized by utilizing an electric or magnetic method, and particularly relates to a hall type vehicle chassis height sensor used for vehicle light control. The vehicle chassis height sensor comprises a shell, a rotation unit, a swing arm unit and a hall sensing unit, wherein the rotation unit includes a rotary shaft and a magnetic steel, a first cavity and a second cavity are arranged on the lower portion of the shell, the magnetic steel is placed in the first cavity, a hall chip is flatly posted on a circuit board, close to and aligned to the magnetic steel, the circuit board is fixed in the second cavity through sealing fillers, and the swing arm unit is in an integrated structure by an entire injection molding. A stator portion is omitted, under the condition that the detecting function and accuracy of the sensor are maintained, the manufacturing cost of the sensor is reduced, by means of a swing arm ball stud structure which utilizes curable fillers to perform a sealing perfusion and an entire injection molding, disturbances of an application environment can be reduced, and influences of assembly errors to the accuracy can be reduced, so that the assembly process of the sensor is simple and rapid.

Description

technical field [0001] The invention relates to a vehicle chassis height detection device characterized by adopting an electric or magnetic method, in particular to a Hall type vehicle chassis height sensor used for automobile light control. Background technique [0002] The automotive sensor is a key component of the automotive electronic control system, and it is also the core content of the research in the field of automotive electronics technology. The car light control system needs to control the height of the low beam headlights of the vehicle in time according to the height of the vehicle body and the road surface conditions, so as to prevent the glare generated by the vehicle lights from affecting driving safety. , so the height sensor is required to detect the height of the vehicle chassis in real time. At present, the Hall sensor has been widely used in the field of electronic control due to its advantages of high precision and small size. Among them, the Hall-typ...
