Rotary support structure for sensors

Abstract

The invention discloses a rotary support structure for sensors. The rotary support structure is installed on a rotary shaft of a Hall sensor. The rotary support structure is characterized by comprising a floating bar connector connected with a floating bar, a rotary shaft connector, and a fixing sleeve, wherein the rotary shaft connector connected with the rotary shaft is used for positioning and the fixing sleeve assists the rotary shaft connector in positioning. The floating bar connector is connected with the rotary shaft connector and is L shaped. The top and outside of the floating bar connector are provided with floating bar connecting channels. The rotary shaft connector is disposed on the inside of the floating bar connector and comprises positioning jaws which are mounted on two sides of the rotary shaft and which extend axially along the rotary shaft. Each positioning jaw is provided with an inner arc notch fitting the rotary shaft. The rotary shaft connector is sleeved with the fixing sleeve. The rotary support structure has the advantages that two-point positioning between the structure and the rotary shaft is changed into double-chamber fixation, the structure is more stable, and the service life of the structure is prolonged.

Description

technical field [0001] The invention relates to a rotating support structure of a Hall sensor applied to an automobile fuel tank, and belongs to the technical field of liquid level sensors. Background technique [0002] The sensor used to measure the liquid level parameter on the automobile fuel tank, the more commonly used one is the Hall sensor. At present, the fixing of the rotating shaft of the Hall sensor adopts positioning points symmetrically arranged on both sides of the shaft, and the connection position between the floating rod and the rotating shaft is also far away from the positioning point, which makes the driving position of the floating rod as the driving rod far away from the positioning point. As the position of the anchor point of the fixing device, a certain deviation is caused during the deflection of the rotating shaft, which makes the measurement accuracy not accurate enough. However, due to the requirement of the structural design, the rotating shaft...

Problems solved by technology

At present, the fixing of the rotating shaft of the Hall sensor adopts positioning points symmetrically arranged on both sides of the shaft, and the connection position between the floating rod and the rotating shaft is also far away from the positioning point, which makes the driving position of the floating rod as the driving rod far away from the positioning point. As the position of the positioning point of the fixing device, a certain deviation is caused during the deflection of the rotating shaft, which makes the measurement accuracy not accurate enough

However, due to the needs of this structural design, the rotating shaft is longer, and the torsional strength of the rotating shaft itself is reduced, which affects the service life of the Hall sensor.
