Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
In order to better understand the above technical scheme, the example of the utility model is more fully described below with reference to accompanying drawings
Property embodiment.Although showing the exemplary embodiment of the utility model in attached drawing, it being understood, however, that can be in a variety of manners
It realizes the utility model and should not be limited by the embodiments set forth herein.It is to be able to more on the contrary, providing these embodiments
Thoroughly understand the utility model, and the scope of the utility model can be fully disclosed to those skilled in the art.
Below with reference to the accompanying drawings the liquid level sensor according to the utility model embodiment is specifically described.
Referring to Fig. 1, showing the liquid level sensor in the utility model embodiment.The liquid level sensor is mainly used for
It is mounted on the fuel tank of vehicle, is shown with to monitor the oil mass of fuel tank, combined circuit and processor on the instrument board of vehicle fuel-displaced
Whether case liquid level transfinites.
Specifically, the liquid level sensor includes sensor body 1, sensor body 1 has the spy for being suitable for monitoring oil mass
First 11,11 top perimeter of popping one's head in is arranged with a sealing ring 12, and the top surface of sealing ring 12 is higher than the top surface of probe 11, will couple
Agent 15 is wrapped on probe 11.When specifically used, sealing ring 12 can be used nested mode and be mounted in sensor body 1.
That is the liquid level sensor is by being arranged a sealing ring 12 in 11 peripheries of popping one's head in, and the top surface of sealing ring 12 is higher than probe 11
Top surface so that couplant 15 can be wrapped probe 11 by sealing ring 12；When couplant 15 is using lubricating grease, can prevent from lubricating
The dispensing volatile of rouge outward improves the measurement stability between the sensor and fuel tank 2；When couplant 15 uses coupling substance
When, the coupling effect of ultrasonic wave can be improved, improve the accuracy of 11 measurement data of probe.In this way, pass through the setting of sealing ring 12,
Allow couplant used in the liquid level sensor is stable to be stored on fuel tank 2, is not spilled off and vapors away, pass liquid level
Sensor 1 is steadily coupled with fuel tank, or do not have to glue it is fixed when, can make liquid level sensor is more stable to be mounted in fuel tank 2.
To guarantee that sensor body 1 more rapidly, is steadily assembled with fuel tank 2；In the present embodiment, sensor body 1 is logical
It crosses the first magnetic absorption member 13 to cooperate with 2 magnetic of fuel tank, sensor body 1 is removably attached on the outer surface of fuel tank 2.It can
To understand ground, the mounting means that existing liquid level sensor uses glue directly to paste or punch, the sensor body 1 are compared
(i.e. liquid level sensor) is mounted on fuel tank 2 by the way of magnetic suck.In this way, passing through the first magnetic absorption member 13 for sensor body
1 is mounted on fuel tank 2, so that the installation of liquid level sensor is not necessarily to live the waiting glue curing of sensor body 1 with hand rest, without
It is in addition punched on fuel tank 2, simplifies installation steps, and improve the reliability of installation, reduced because glue layer is easy by heat expansion
The influence of shrinkage, glue is easy to crack or separates, and causes the coupling effect of glue poor, leads to the influence of measurement data inaccuracy.
Specifically, in conjunction with Fig. 2 and Fig. 3, liquid level sensor according to the present utility model, probe 11 is for monitoring oil
Oil mass (or liquid level) in case 2, sensor body 1 are removably attached to the bottom of fuel tank 2, and probe 11 is made to be close to fuel tank 2
The outer surface of bottom monitors the oil mass in fuel tank 2 in a manner of through ultrasonic measurement.Therefore, which can be
Ultrasonic sensor.Ultrasonic sensor can have piezoelectric chip in aluminum hull probe 11 using commercially available.Work as sensing as a result,
After device ontology 1 collects the analog signal of 2 liquid level of fuel tank, digital signal is converted by A/D sensor, and digital signal is passed
The processor being defeated by vehicle carries out processing analysis, calculates true level value by processor, judges whether to transfinite by operation
Alarm, and by result in instrument board and interior display.Certainly, the data processing of processor, which can also gather, is arranged in sensor body
In 1.Since programmable processor is the prior art, it is not described in detail herein.
In some instances, referring to Fig. 2, fuel tank 2 can be irony fuel tank；In this way, passing through the direct magnetic of the first magnetic absorption member 13
The outer surface of 2 bottom of fuel tank is adsorbed on, it can be achieved that the installation between sensor body 1 and fuel tank 2 is fixed.Specifically, sensing
Device ontology 1 can have the open fitting groove 14 in top, and strong magnet then can be used in the first magnetic absorption member 13, and by the way that strong magnet to be embedded
In fitting groove 14, realize that the installation between sensor body 1 and the first magnetic absorption member 13 is fixed, and then pass through the first magnetic absorption member 13
Sensor body 1 is mounted on the outer surface of 2 bottom of fuel tank.
In some instances, referring to Fig. 3, fuel tank 2 can be non-ferrous fuel tank, in this way, can by fuel tank 2 be equipped with
Second magnetic absorption member 21 of 13 magnetic of the first magnetic absorption member cooperation, to realize that the installation between sensor body 1 and fuel tank 2 is fixed.Tool
For body, sensor body 1 can have the open fitting groove 14 in top, and strong magnet then can be used in the first magnetic absorption member 13, and passes through
Strong magnet is embedded in fitting groove 14；Second magnetic absorption member 21 then can be used iron block or magnet and be arranged in fuel tank 2, and in fuel tank
13 magnetic of the first magnetic absorption member of 2 outer surfaces cooperates, and sensor body 1 is mounted on the outer surface of 2 bottom of fuel tank.Certainly,
When the second magnetic absorption member 21 is using magnet, using the magnet with the mutual magnetic of the first magnetic absorption member 13.
In addition, being also provide with a protection cap 3 in the present embodiment, in sensor body 1, protection cap 3 can make sensor body 1
It is not moved position or it is prevented to be destroyed because of external force factor.
The mounting structure of liquid level sensor and fuel tank 2 in the related technology is all that installation is pasted or punched by glue, is held
Easily there is glue layer to be easy by the influence expanded with heat and contract with cold, glue is easy to crack or separates, and causes the coupling effect of glue poor, causes
The influence of measurement data inaccuracy；And punch can destroy original Oiltank structure, it is erroneous for installation the problems such as.However, according to this reality
With the liquid level sensor mounting structure of new embodiment, liquid level sensor is mounted on fuel tank 2 by way of magnetic, it can be with
Simply, it effectively and quickly realizes the assembly between liquid level sensor and fuel tank 2, protects the original structure form of fuel tank, improve peace
The reliability and maintainability of dress guarantees the monitoring that vehicle fuel tank fuel quantity can be continual and steady, improves vehicle fuel quantity measurement data
Accuracy.
