After the transducer is arranged in the long, narrow and sloping motorcycle fuel oil tank and connected with the associated circuits, the transducer can really reflect the variation situation of the fuel oil quantity of the fuel oil tank any time, and causes the motorcycle user to be able to know the fuel oil quantity of the fuel oil tank any time in order to accurately control the admission occasion of the motorcycle fuel oil.
Description
Technical field
The utility model relates to and a kind ofly is installed in long and narrow and in the motorcycle tank that tilts, is used to monitor the fuel sensor that fuel level changes.
Technical background
Fuel sensor is installed in the motorcycle tank bottom, is used for monitoring the amount of fuel of fuel tank.Existing fuel sensor is generally single float-type, and when fuel level in the fuel tank arrives a certain position and can not the float in the sensor be floated the time again, this sensor is connected a circuit and sent caution.This kind fuel sensor can only just can make the circuit arrangement that is attached thereto send caution when fuel level arrives a certain position, and can not make relevant circuit arrangement reflect the situation of change of amount of fuel in the motorcycle tank.Particularly for long and narrow as crown prince's type motorcycle and fuel tank that tilt, if the existing structure fuel sensor is installed in the place, higher position of fuel tank lower curtate, when sensor connection circuit sent caution, (the low oil level district of fuel tank) still had enough fuel oils for motorcycle driving at fuel tank lower position place; If the existing structure fuel sensor is installed in the lower position place of fuel tank lower curtate, when sensor is not also connected warning circuit, trapped fuel in the fuel tank deficiency so that motorcycle driving, so for long and narrow and motorcycle tank that tilt, existing fuel sensor can not truly reflect the situation of amount of fuel in the fuel tank.
The utility model content
The purpose of this utility model provides a kind of high low level fuel sensor, after the interlock circuit device is connected, and the situation of change motorcycle tank that tilt in amount of fuel long and narrow with true reflection.
High low level fuel sensor described in the utility model, mainly by support, high, the low oil level float, high, low oil level float control lever, high, low oil level variable resistor silk, sliding pin of resistance wire and compression spring are formed, high, the low oil level float is separately fixed at height, one end of low oil level float control lever, high, the other end of low oil level float control lever is rack-mount respectively, and can rotate around support, high, low oil level variable resistor silk is fixed on the support, and lay respectively at rack-mount height, low oil level float control rod end below, and it is high, low oil level float control lever is fixed with the sliding pin of resistance wire at this end separately, be provided with compression spring between sliding pin of resistance wire and support, compression spring is sleeved on height, on the low oil level float control lever, make the sliding pin of two resistance wires respectively with height, low oil level variable resistor silk keeps in touch; Described high oil level float control lever length is less than low oil level float control lever length; Support is provided with limiting plate, limiting the slewing area of high and low oil level float control lever with respect to support, and the extreme lower position of high oil level float and the extreme higher position of low oil level float is on the same surface level.
Should be installed in place, motorcycle tank inner bottom part higher position by high low level fuel sensor, high and low oil level float is suspended in the fuel oil, its position changes with the variation of oil level, thereby high and low oil level float control lever is rotated with respect to support, drive the sliding pin of two resistance wires then and on high and low oil level variable resistor silk, slide respectively.High and low oil level variable resistor silk and the sliding pin of the resistance wire that is in contact with it constitute two variohms, and its resistance value changes with the variation of high and low oil level float position.Its series connection is inserted in motorcycle interlock circuit, and the variation of electric current reflects the variation of amount of fuel in the motorcycle tank in the circuit that the fuel level gauge in the circuit can cause according to two variohm resistance change.
The utility model is owing to have this kind structure, the variation that makes fuel level in the motorcycle tank reflects by the variation of the high and low oil level variohm resistance value that is made of high and low oil level variable resistor silk and the sliding pin of resistance wire that is in contact with it, and the variation of this resistance value will cause the variation of electric current in the circuit, reflect by the fuel gage in the circuit the most at last, thereby the variation of amount of fuel in the motorcycle tank can be reflected at any time.Because the limiting plate that is provided with on this sensor stand can limit height, low oil level float control lever is with respect to the slewing area of support, high oil level float and control lever high oil level district in fuel tank is moved, and low oil level float and control lever low oil level district in fuel tank moves, and the extreme higher position of the extreme lower position of high oil level float and low oil level float is on the same surface level, like this when fuel level is in high oil level district, the variation of electric current is caused by the variation of high oil level variohm resistance value in the circuit, and when fuel level drops to the low oil level district, the variation of electric current is then caused by the variation of low oil level variohm resistance value in the circuit, so this sensor is installed in long and narrow in the motorcycle tank that tilts with after the interlock circuit device is connected, the situation of change that can truly reflect amount of fuel in the fuel tank, the motorcycle user can be known at any time what of fuel oil in the fuel tank add opportunity with accurate grasp motorcycle fuel.
