Description
Technical field
The utility model relates to a kind of fuel oil pump assemblies applied in automobile oil supply system, and in particular to a kind of fuel pump
The fuel level sensor of assembly.
Background technique
The effect of fuel oil pump assembly is that the fuel oil being stored in fuel tank is delivered in the fuel pipe of fuel injector, supply
The fuel oil of fuel injector certain pressure, fuel injector drive automobile engine to work according to the instruction oil spout of ECU.Traditional combustion
The working principle of oil pump assy, fuel level sensor is, when automotive oil tank oil level height changes, to pass through float bracket
Rotation slides the hard contact installed in float bracket on resistor disc surface to make resistance generate variation, and then to sentence
The variation of oil-break position.The disadvantage is that: structure is complex, and due to using contact type structure, hard contact and resistor disc
There are sliding frictions to be unfavorable for the raising of service life so measurement accuracy is not high and breakpoint easily occurs, and is connected to floating
Float on submounts is inconvenient to adjust, and assembly is inconvenient.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of this utility model be to provide a kind of structure is simple, measurement accuracy is high,
It is easy to assembly, and it is less prone to breakpoint, effectively improve the oil-level sensor of service life.
The utility model is implemented by the following technical programs:

Make circle swing setting around stem, float bracket is provided with two block permanent magnets, and two block permanent magnets are made centered on the stem
It is symmetrical set.
The oil-level sensor of above-mentioned technical proposal, when automotive oil tank oil level height changes, float bracket
Rotation will drive permanent magnet and be rotated, and the magnetic field induction between permanent magnet and Hall chip will become in the energized state
Change, then by the variation of voltage can determine whether Fuel Remained in fuel tank number.Since there is no contacts for above-mentioned measurement process
The sliding friction of mode, and the magnetic field induction head of Hall chip is completely built-in, so measurement accuracy is high and is less prone to breakpoint,
Effectively improve service life.
To realize the convenient for assembly of resistance plate rack and float bracket, and guarantee after assembly to be not in be axially disengaging, make
To be preferred, the top of the stem is equipped with minor diameter cylinder, and the top of minor diameter cylinder connects the limited block that oriented two sides extend,
The center of the float bracket is equipped with cylindrical hole and is located therein by mandrel rotation, and the hole wall of cylindrical hole is equipped with annular gear, annular gear
Position correspond to minor diameter cylinder, annular gear be equipped with allow the limited block axially through notch.
For convenience of assembly, permanent magnet is fixed on the positioning preferably, being equipped with catching groove in the float bracket, catching groove
Open end is equipped with two snap fingers, between two snap fingers can elasticity strut.
For convenience of position adjustment of the float on float bracket, preferably, the front of the float bracket is equipped with side by side
