Description
Technical field
The utility model relates to liquid level detecting sensor field, is specifically related to a kind of external labeling type liquid level sensor.
Background technology
On current automobile oil mass supervisory system market, oil tank liquid level sensor mainly contains: magnetic red variable resistance level transducer, sliding rheostat liquid level sensor, capacitance level transducer, pressure liquid level sensor, perforate survey air type ultrasonic sensor five kinds.What market share was the highest is magnetic red variable resistance level transducer and sliding rheostat liquid level sensor, the general resolution of these sensors above-mentioned is low, measuring error is larger, need when mounted to change fuel tank internal structure simultaneously, easy damage fuel tank, and when medium is similar be gasoline time, the danger of easily blasting.In a word, the demand that traditional oil mass supervising device can not meet vehicle operators under energy-saving and emission-reduction megatrend, driver controls oil consumption, and install complicated, have potential safety hazard.
Summary of the invention
The utility model provides a kind of novel external labeling type liquid level sensor, to solve, the general resolution of liquid level sensor in prior art existing automobile oil mass supervisory system is low, measuring error is larger, and need when installing to change Oiltank structure, be not easy to install, have the danger of blast to there is potential safety hazard.
The technical scheme that the utility model is taked is: provide a kind of external labeling type liquid level sensor, sensor is made up of shell, matching layer, ultrasound wave ceramic wafers layer, casing state aware layer, pin interfaces and cushion, described sensor adopts the mounting means of external labeling type, be bonded in tank floor medium position, by the ultrasound wave ceramic wafers layer in application external source driving sensor, send original mechanical ripple and receive the mechanical wave that surface reflections returns, realizing carrying out preliminary surveying to the liquid level in casing.
Positive progressive effect of the present utility model is: be affixed on tank floor outside sensor, and without the need to changing body structure, be easy to install, level of integrated system is high, use safety; The mechanical wave produced by ceramic wafers carries out preliminary surveying to the liquid level in casing, the speed namely utilizing mechanical wave to propagate in a liquid and send out, receive the relation in the time interval and draw; Also be integrated with the casing state aware layer of the status data of exportable casing, carry out assistant analysis and go out data liquid level true altitude in casing, effectively achieve the high resolving power of casing level sensing, the accuracy of data, reliability.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the utility model external labeling type liquid level sensor
Fig. 2 is the constitutional diagram that the utility model external labeling type liquid level sensor loads in fuel tank.
Embodiment
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model external labeling type liquid level sensor 11 is metal material shell 1 structure, shell 1 is embedded from the bottom to top respectively by matching layer 2(such as epoxy resin, metal material, the materials such as poly-milling imines), ultrasound wave ceramic wafers layer 3, casing state aware layer 4(material is circuit boards), stacked formation, wherein matching layer 2 is embedded among the cell body 10 of shell 1 bottom, ceramic wafers layer 3 is close to colloidal materials 8 and is sticked on matching layer 2, casing state aware layer 4 is placed and is fixed on the inner draw-in groove 9 of case body (being positioned at above ceramic wafers layer 3), shell 1 housing side leaves perforate to draw by the pin interfaces 5 of wire 7 for connect box state aware layer 4 and ceramic wafers layer 3, and be colloidal materials by cushion 6, wrap by carrying out encapsulating cooling realization after high temperature melting, play the effect (as Fig. 1) of buffering and protection, matching layer 2 is for the protection to ultrasound wave ceramic wafers layer 3 simultaneously, and carries out acoustic reactance coupling to the ultrasound wave that ultrasound wave ceramic wafers generates, and makes the ultrasound wave generated more be conducive to sensing and detection, metal material shell 1 can make it more reliably bond together with casing 13, and vehicle status data can be provided to adapt to use occasion in conjunction with casing state aware layer 4, guarantees the accuracy of liquid level data.Each signal wire of ultrasound wave ceramic wafers layer 3 and casing state aware layer 4 connects extraction by pin interfaces 5, and cause outside provides driving source and digital independent.
The utility model needs outside to apply driving source by pin interfaces 5, ultrasound wave ceramic wafers is impelled to produce deformation, then the mechanical wave 12 for detecting is produced, mechanical wave 12 is through matching layer 2, at testing liquid Propagation, reflect at dielectric interface, reflected mechanical waves signal is returned by original route, pass ultrasound wave ceramic wafers layer 3 back, ceramic wafers receives return signal and exports.Apply external drive rear box state aware layer 4 and enter duty, detect current vehicle status data.In conjunction with the signal of ultrasound wave ceramic wafers layer 3 and the output data of casing state aware layer 4, realize the sensing measurement of casing liquid level 14.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its in instructions still can be modified to the technical scheme that foregoing embodiments is recorded, or equivalent replacement is carried out to wherein portion of techniques feature, does not make the essence of appropriate technical solution depart from the spirit and scope of the utility model embodiment technical scheme.
