Description
Technical field
The utility model relates to fuel level sensor technical field, particularly a kind of automobile oil level sensor.
Background technology
Automobile display oil level number must rely on fuel level sensor.Present fuel level sensor is the change being shown resistance value by the slip between thick-film resistor sheet and brushing piece, calculates in fuel tank to also have how much gasoline finally by signal intensity.Its structure be brush plate be directly installed on resistor disc surface directly contact with gasoline.Because circle contact is that pressure contacts with resistor disc, require that contact is pressed in the pressure of resistor disc necessary very well, between 0.2 ~ 0.3N.Be less than 0.2N and can produce loose contact, be greater than 0.3N and return the minimizing of generation abrasion resistance.The height of such contact must be consistent.If inconsistent, the pressure produced on potsherd conductor is in different size, thus abrasion resistance different produced, and life-span of automobile oil surface sensor has longly to be had short, and reliability is bad.Pressure size just because of brush plate is difficult to control, and brush plate slidably reciprocates and conduction band rubbed on conductor, there will be the phenomenon of sensor frequent breakage.
Secondly, resistor disc soaks in the oil, and it is too large that the not high or brush plate of the purity due to gasoline is pressed in resistor disc upward pressure, and long-time use can produce resistor disc surface oxidation and conduction band draws the phenomenons such as disconnected.Thus the resistance value of display is incorrect, so oil level display is also inaccurate.
Utility model content
The purpose of this utility model is: be difficult to control to overcome existing fuel level sensor resistor disc pressure size, the easy oxidative wear of resistor disc, sensor degradation, oil level is caused to show the problems such as inaccurate, provide a kind of novel automobile oil level sensor, utilize the material different from original sensor, and add resistor disc shell, make fuel level sensor not by the pollution of the impurity of gasoline, add wearing quality, improve its serviceable life.
The utility model solves the technical scheme that its technical matters adopts: a kind of automobile oil level sensor, there is ceramic substrate, ceramic substrate is provided with resistor disc, ceramic substrate outside is provided with the plastic casing of an opening, plastic casing opening part is provided with a cover plate, cover plate seals with plastic casing and connects, in shell, resistor disc surface is provided with a magnetic cylinder, plastic casing reverse side and resistor disc corresponding position are provided with a plastics rocking arm, another magnetic cylinder is installed in plastics rocking arm, resistor disc front magnetic cylinder holds mutually with resistor disc reverse side magnetic cylinder, the lead-in wire of resistor disc is connected with the connector on cover plate, connector outside cover plate is connected with the lead-in wire of oil pump.
Described cover plate is integrated the moulding of injection mo(u)lding.
Described cover plate outside is perfused with one deck epoxy resin, and the whole plastic casing of sealing after solidification, prevents gasoline from immersing in plastic casing.
The beneficial effects of the utility model are: plastic casing is whole to be sealed completely, and resistor disc does not reach gasoline, so resistor disc can not be oxidized; Next is that magnetic cylinder changes ball float upper-lower position along with the number of gasoline, thus drive each wire of magnetic cylinder contacts resistor disc, produce different resistances, magnetic cylinder and the resistor disc surface of plastic casing are Structure deformation, greatly reduce friction each other like this, thus resistor disc is multiplied friction durability, abrasion resistance is increased to more than 5,000,000 times more than 1,000,000 times from original requirement, and serviceable life improves greatly.
Whole defects of prior art can be overcome by the technical solution of the utility model, such fuel level sensor, not by gasoline contamination, more greatly increases the abrasion resistance of resistor disc, qualification rate and the serviceable life of this product improve greatly, are the once changes of fuel level sensor.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, 2, shown in 3, a kind of automobile oil level sensor, comprise ceramic substrate 1, plastic casing 3, cover plate 4, magnetic cylinder 5 and plastics rocking arm 6, ceramic substrate 1 is provided with resistor disc 2, the plastic casing 3 of an opening is installed in ceramic substrate 1 outside, plastic casing 3 opening part installs cover plate 4, cover plate seals with plastic casing 3 and connects, in shell 3, resistor disc 2 surface is provided with a magnetic cylinder 5, plastic casing 3 reverse side and resistor disc 2 corresponding position are provided with a plastics rocking arm 6, another magnetic cylinder is installed in plastics rocking arm 6, resistor disc 2 front magnetic cylinder 5 holds mutually with resistor disc 2 reverse side magnetic cylinder, the lead-in wire of resistor disc 2 is connected with the connector on cover plate 4, connector outside cover plate 4 is connected with the lead-in wire of oil pump.
Principle of work of the present utility model is: first, magnetic cylinder along with gasoline number and change the upper-lower position of ball float, thus each wire of magnetic cylinder contacts resistor disc in drive plastic casing, produce different resistances, because magnetic cylinder and resistor disc are Structure deformation, there is not very large pressure, therefore substantially increase abrasion resistance, the qualification rate of product and serviceable life are improved greatly.
Do not immerse in plastic casing to solve long-time gasoline, the sealing of plastic casing is just quite important.The utility model is first made by cover plate to mould that to put into air bag inserts one system molded, then on the cover board infusion epoxy resin, namely seals, thus ensure housing not oil-feed, and then reach the effect that resistor disc is not oxidized, abrasion resistance improves greatly after waiting solidification.
