Abstract
The utility model discloses a level sensor of car oil tank, including mounting flange, stand and float, mounting flange and oil tank fixed connection, be equipped with a plurality of reed capsule in the stand, the float cover is established on the stand, and its inside magnet that is equipped with the response reed capsule, it still includes a barrel, and the float is including the ring sum a plurality of slip float wheel that floats, the ring cover that floats is established on the stand, the slip float wheel with the outside limit swivelling joint who floats and encircle, just the slip float wheel still with the inside wall of barrel is inconsistent. The utility model discloses an introduce fluid to the inside of barrel, it is undulant to reduce the fluid liquid level to utilize the sliding contact between slip float wheel and cylinder side wall, drive the ring that floats and reciprocate, avoided unsteady ring reciprocating in -process and stand emergence jamming or impacting the stand, improved level sensor's life effectively.
Description
Technical field
The utility model relates to sensor technical field, particularly relates to a kind of liquid level sensor of automotive oil tank.
Background technology
At present, the oil tank liquid level sensor on market comprises a root post, and column is inner, and along short transverse being evenly equipped with some reed capsules, column outer cover has float, is provided with magnet above float, relies on the induction of magnet and reed capsule can measure the height of oil tank liquid level.This liquid level sensor structure is simple, and performance is also reliable.But, due to when driving, the fluid in fuel tank there will be larger fluctuation unavoidably, and float to move up and down in process easily and column generation clamping stagnation or clash into column, so not only make the liquid level measurement of fuel tank occur error, and affect the serviceable life of liquid level sensor.
Utility model content
The utility model mainly to solve in prior art existing technical matters, thus provide a kind of and measure accurately, the liquid level sensor of the automotive oil tank of long service life.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
The liquid level sensor of the automotive oil tank that the utility model provides, comprise assembly flange, column and float, described assembly flange is fixedly connected with fuel tank, several reed capsules are provided with in described column, described float is set on described column, and its inside is provided with the magnet of reaction tongue reed pipe, it also comprises a cylindrical shell, described cylindrical shell is fixed on the lower surface of described assembly flange, and be set in the outside of described column, wherein, the bottom of described cylindrical shell is also symmetrical is provided with two oil-ins, the inside of described cylindrical shell is connected by the inside of described oil-in with described fuel tank, and described float comprises floating ring and several slip bouyant wheels, described floating ring is set on described column, described slip bouyant wheel is rotatably connected with the outer side edges of described floating ring, and described slip bouyant wheel is also inconsistent with the madial wall of described cylindrical shell.
Further, the quantity of described slip bouyant wheel is four, and is evenly distributed in described floating ring circumferentially.
Further, a gap is provided with between described floating ring and described column.
Further, the bottom of described cylindrical shell is also provided with one deck filter screen.
The beneficial effects of the utility model are: by fluid being introduced into the inside of cylindrical shell, reduce fluid liquid fluctuating, and utilize the sliding contact between slip bouyant wheel and cylinder lateral wall, drive floating ring moves up and down, avoid floating ring to move up and down in process with column generation clamping stagnation or clash into column, effectively improve the serviceable life of liquid level sensor.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the liquid level sensor of automotive oil tank of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, the liquid level sensor of automotive oil tank of the present utility model, comprise assembly flange 1, column 2 and float, assembly flange 1 is fixedly connected with fuel tank 3, several reed capsules 4 are provided with in column 2, float is set on column 2, and its inside is provided with the magnet 5 of reaction tongue reed pipe 4, it also comprises a cylindrical shell 6, cylindrical shell 6 is fixed on the lower surface of assembly flange 1, and be set in the outside of column 2, wherein, the bottom of cylindrical shell 6 is also symmetrical is provided with two oil-ins 7, the inside of cylindrical shell 6 is connected by the inside of oil-in 7 with fuel tank 3, and float comprises floating ring 8 and several slip bouyant wheels 9, floating ring 8 is set on column 2, slip bouyant wheel 9 is rotatably connected with the outer side edges of floating ring 8, and slip bouyant wheel 9 is also inconsistent with the madial wall of cylindrical shell 6.The utility model is by being introduced into the inside of cylindrical shell 6 by fluid, reduce fluid liquid fluctuating, and utilize the sliding contact between slip bouyant wheel 9 and cylindrical shell 6 sidewall, floating ring 8 is driven to move up and down, avoiding floating ring 8 moving up and down in process there is clamping stagnation or clashes into column 2 with column 2, effectively improve the serviceable life of liquid level sensor.
Concrete, in order to make floating ring 8 stress equalization, be convenient to synchronous rising or decline, the quantity of slip bouyant wheel 9 is four, and is evenly distributed in floating ring 8 circumferentially.Preferably, between floating ring 8 and column 2, be provided with a gap 10, avoid floating ring 8 moving up and down in process and clash into column 2.Preferably, in order to reduce the impact of liquid level sensor on fuel tank 3 fluid, the bottom of cylindrical shell 6 is also provided with one deck filter screen 11.
Above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
