Abstract
The utility model discloses a fuel liquid level sensor for vehicles. The fuel liquid level sensor for vehicles is characterized by comprising a strip-shaped circuit board arranged in a plastic casing, wherein a plurality of electronic sensors are arranged in the length direction of the strip-shaped circuit board at equal intervals and electrically connected with an integrated circuit (IC) microprocessor. The fuel liquid level sensor has the advantages that the noncontact electronic structure is adopted for replacing the mechanical contact type structure in the prior art to measure the fuel liquid level, the structure is simple, the service life is long, and the measuring precision is high.
Description
Technical field
The utility model relates to a kind of sensor, what be specifically related to is a kind of fuel oil for vehicles liquid level sensor.
Background technology
The fuel liquid level sensor of prior art all adopts Mechanical Contact formula structure; Adopt silver contact contact the output signal with thick-film resistor, because silver contact, makes the thick-film resistor long term wear for a long time in the surperficial slip of thick-film resistor; Contact with gasoline for a long time; Not corrosion-resistant, serviceable life is short, inaccurate phenomenon occurs measuring.
Summary of the invention
Problem in view of known technology existence at present; The technical matters that the utility model will solve is to be to provide a kind of Mechanical Contact formula structure that adopts the contactless electronic structure to replace prior art; Simple in structure, long service life, the fuel oil for vehicles liquid level sensor that measuring accuracy is high.
For solving the problems of the technologies described above, the utility model takes following technical scheme to accomplish:
The fuel oil for vehicles liquid level sensor; It is characterized in that: said fuel oil for vehicles liquid level sensor comprises the bar shaped wiring board that is installed in the plastic casing; Bar shaped wiring board equidistance along its length is provided with several electronic inductors, and electronic inductor is electrically connected with the IC microprocessor.Said electronic inductor is established 16 altogether.
The utility model utilizes electronic inductor to detect the fuel oil position of fuel tank, passes the signal to fuel gauge again, thus the stored amount of fuel of fuel tank that gets.The utility model is improved to electronic type with the fuel liquid level sensor of Mechanical Contact formula structure, under the state that fuel oil is fully loaded with, and 16 electronic inductors of fuel oil submergence; This moment, fuel gauge showed full lattice, behind running car one segment distance, and the fuel oil loss; This moment, 16 electronic inductors were judged amount of fuel at that time; Send information on the wiring board IC processor, the IC processor is judged transmission fuel gauge in back to information, shows amount of fuel at that time.The electronic type fuel liquid level sensor is contactless design, can solve fully physical construction the problem that can not accomplish, sensor signal output is steadily; The inerrancy amount of fuel at that time of reporting to the police, sensor output signal need be through the auxiliary sensings of any way, as long as when fuel oil at that time is lower than any one of 16 inductors; Fuel gauge can be judged oil mass at that time, and measuring accuracy is high, and 16 inductors are immersed in the fuel oil for a long time; Can not corrode long service life.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model.
Embodiment
Accompanying drawing has been represented the technical scheme and the embodiment of the utility model, combines accompanying drawing to further describe each relevant details and principle of work thereof of embodiment below again.
With reference to accompanying drawing 1; This kind fuel oil for vehicles liquid level sensor; Comprise the bar shaped wiring board 2 that is installed in the plastic casing 1, bar shaped wiring board 2 equidistance along its length is provided with 16 electronic inductors 3, and electronic inductor 3 is electrically connected with IC microprocessor 4; Three terminals are arranged on the bar shaped wiring board 2, be respectively electrode input end 5, negative input 7 and signal output terminal 6.
Above-mentioned fuel oil for vehicles liquid level sensor is work like this: under the state that fuel oil is fully loaded with, and 16 electronic inductors of fuel oil submergence, this moment, fuel gauge showed full lattice; Behind running car one segment distance; The fuel oil loss, this moment, 16 electronic inductors were judged amount of fuel at that time, sent information on the wiring board IC processor; The IC processor is judged transmission fuel gauge in back to information, shows amount of fuel at that time.
