Abstract

The invention belongs to the technical field of automobile sensor fixing modes, and relates to a liquid level sensor bottom end fixing structure which comprises a liquid level sensor and further comprises a box body, the liquid level sensor is fixedly connected with the top of the box body, a groove is formed in the bottom of the box body, an elastic base is arranged in the groove, and the elastic base is fixedly connected with the box body. The bottom of the liquid level sensor is clamped with the elastic base and extrudes the elastic base, and the liquid level sensor fixing device has the advantage that the liquid level sensor is fixed more firmly.

Description

technical field [0001] The invention belongs to the technical field of automobile sensor fixing methods, and in particular relates to a bottom fixing structure of a liquid level sensor. Background technique [0002] The liquid level sensing of fuel tanks and urea tanks (diesel vehicles) in automobiles is an important monitoring item in emission regulations; at present, reed switch technology is mainly used to detect liquid levels. The sensor arranges different resistances into "rod"-shaped parts, and the buoy parts on the "rod" "float" with the liquid level of fuel or urea aqueous solution, and at the same time change the resistance value signal corresponding to different liquid levels to achieve Liquid level detection purpose. In addition, according to the different requirements of the vehicle, the sensor can also take into account multiple functions such as solution heating, concentration monitoring, temperature monitoring, and filtration and suction. [0003] The "rod" ...
