Abstract
The invention relates to a sealed type automobile oil level sensor, comprising a substrate, an external rocker, an internal rocker, an upper cover and a sieve; a circuit is arranged inside the substrate, a spring leaf is arranged on the internal rocker and is electrically connected with the circuit, a spring lead is sheathed with the internal rocker and is connected to the wire; a float rod is connected with the external rocker, the external rocker is inserted in the substrate and is in cuttage grafting with the internal rocker; through holes are arranged on the upper cover, the sieve is arranged on the through holes; the upper cover is connected with the substrate in a chucking way. The sensor further comprises an aluminium plate which carries out injection molding, beam enveloping and forming with the upper cover; in the invention, the traditional sensor is enveloped, so that oil for vehicles has to go through the sieve to be contacted with the sensor circuit, the inner oil for vehicles can reach an ideal clean state, thus overcoming influence of poor oil on service life and property of the sensor and having the advantages of long service life and stable working performance.
Description
Technical field
The present invention relates to a kind of sensor, relate in particular to a kind of sealed type automobile oil level sensor group and stand.
Background technology
Oil box level sensor for vehicle is applied to the vehicle fuel supply system, its induction and output level height value, after making automobile instrument receive signal, deal with and show level height, for the driver provides fuel tank oil mass information, so that the in good time fuel up of driver prevents to cause vehicle stagnation of movement midway because of fuel oil exhausts.
See also Fig. 1, it is the structural representation of existing open fuel level sensor, and this open fuel level sensor comprises sensor stand 11, circuit board 12, fly rod 13 and float 14.Circuit board 12 is fixed on the sensor stand 11, and circuit board 12 is connected with fly rod 13 tops, the fly rod 13 terminal floats 14 that connect.Its principle of work is: on mechanism design, the variable resistive film on the height of oil level and the circuit board 12 has a predetermined corresponding relation.During work, float 14 change with level height in fuel tank fluctuates, and drives reed by fly rod 13, and reed lifting with oil level on circuit board 12 is slided, and exports the resistance value of different oil level correspondences to vehicular meter.
Fuel level sensor is installed on the electric fuel pump assembly, and electric fuel pump assembly is installed in and directly is immersed in the automotive oil tank in the fuel oil, and therefore, fuel level sensor also directly is immersed in the fuel oil.Yet; carrying a lot of suspended particles secretly through regular meeting in the fuel oil of some bad oil products, these suspended particles can wear and tear reed contact and variable resistive film also can make reed contact and variable resistive film loose contact; cause the circuit board breakpoint, shortened the serviceable life of fuel level sensor greatly.In addition, in the fuel pump course of work, suspended particle also can produce static, influences the accuracy of fuel level sensor resistance output.
In sum, prior art exists the serviceable life of open fuel level sensor and performance to be subjected to bad oil product to influence serious technical matters.
Summary of the invention
The object of the present invention is to provide the good sealed type automobile oil level sensor of a kind of long service life and performance, be subjected to bad oil product to influence serious technical matters with serviceable life and the performance that solves existing open fuel level sensor.
For achieving the above object, the invention provides a kind of sealed type automobile oil level sensor, comprising: base, outer rocker arm, inner rocker arm, loam cake and filter screen, circuit board are arranged on base inside; Reed is arranged on the inner rocker arm and electrically connects with circuit board, and spring lead and inner rocker arm socket also are connected to lead; Fly rod is connected with outer rocker arm, and outer rocker arm is arranged in base and inner rocker arm is pegged graft; Loam cake is provided with through hole, and filter screen is arranged on the through hole; Loam cake and base clamping.
According to the described sealed type automobile oil level sensor of preferred embodiment of the present invention, it also comprises an aluminium sheet, and this aluminium sheet is connected with loam cake.
The present invention adopts closed, automobile-used oil net filtration after filtration enters sensor again, most suspended particle can not enter sensor internal through the filtration of filter screen, has reduced reed contact and influences such as variable resistor pad wear and circuit board breakpoint that suspended particle causes sensor.In addition; the present invention also is provided with an aluminium sheet; automobile-used oil is after filtration behind the net filtration; still have a small amount of molecule and enter sensor internal; when fuel pump is worked; the charged microparticle that produces can be attracted on the aluminium sheet, has avoided the influence of charged microparticle to resistance output, makes resistance of sensor output accurately.Sealed type automobile oil level sensor of the present invention has overcome the influence of bad oil product, guaranteed that the gasoline that contacts with the contact with circuit board cleans, prolonged the serviceable life of circuit board and contact, and the height that can accurately reflect the fuel tank intermediate fuel oil, compared with prior art, the present invention has long service life, the advantage of stable work in work.
