Abstract
The utility model relates to an indicating device of a fuel level in tank of a motor vehicle, in particular to a position transducer that adopts moving magnetic elements to drive dry reed pipe array elements to output different resistance signals varying with positions of the magnetic elements. The dry reed pipe array position transducer consists of a detecting unit equipped with a thick-film resistor network baseplate, a fixed partition insulator and a boot cap, a rotatable part with a swivel arm and an axis of rotation, and a fixed support. The dry reed pipe array is fixed on the back of the thick-film resistor network baseplate. Magnetic elements are arranged in the swivel arm to match with the dry reed pipe array. The utility model is characterized in occupying very little space and prevention of impact of environmental extremes on sensors effectively, simple manufacturing process, accurate location, compactness, low price, safety and reliability, small mechanical wear and long performance life and so on.
Description
Technical field
The utility model relates to the indicating device of motor vehicles fuel level in tank, and that adopts especially that the motion magnetic element drives the tongue tube array element exports the position transducer of different resistance signals with position change.
Technical background
The current position sensor adopts the mode of magnetic element that Hall element position transducer and dried spring magnetic position sensor are arranged, and they exist separately, and required installing space is big, serviceable life is short, the more high defective of manufacturing cost.
Summary of the invention
The purpose of the utility model is to disclose a kind of required tongue tube array position sensing device that installing space is less, serviceable life is long, manufacturing cost is lower.
The tongue tube array position sensing device that motor vehicle oil tank is used by the detection part that has thick film resistor network substrate, fixed insulation pad and protective cover, has the rotatable parts of swivel arm and rotation axis, and fixing support rack is formed.The back of thick film resistor network substrate is fixed with the tongue tube array, and the magnetic element that cooperates with the tongue tube array is housed in the swivel arm.
The utility model is owing to adopt the tongue tube array to substitute Hall element and tongue tube, and tongue tube array and resistor network partly are an integral body and are in sealing state that shared space is very limited.The motion magnetic element is isolated nothing mutually with detection part and is directly contacted, can stop the influence of rugged surroundings effectively, have also that manufacturing process is simple, an accurate positioning, compact conformation, cheap, safe and reliable, characteristics such as mechanical wear is few, long service life sensor.
