Abstract
An automobile digital oil level meter mainly includes a floater, a sensor, a cover plate, connection wires and a liquid crystal integrated block. The floater is fixed on the sensor which is connected to the cover plate through screws and the cover plate is connected with the liquid crystal through connection wires. The installation is simple because the structure and the installation method of the oil, and the hole position and size of the automobile meter plate are not changed. The data can be displayed through a precise digital liquid crystal and can be read precisely and clearly. A singlechip with a high density of integration and many functions, and the computing and control are realized by the computer software. The automobile digital oil level meter has the performances of a shake, bump and interference prevention, and a high reliability and a long lifetime.
Description
(1) technical field
The utility model belongs to instrument field, relates to a kind of Automobile Digital oil level indicator.
(2) background technology
The extensive fuel level in tank table that adopts of China auto manufacturing mostly is magneto-electric analog quantity pointer-type indicating gauge at present, its sensor adopts slide wire resistance to regulate size of current in order to indication oil level height, it is relatively poor to measure accuracy, the driver's observation oil level is easy to generate visual error, for the oil mass storage in the fuel tank and refuel whether capacity also is difficult to accurate judgement.In addition, magneto-electric analog quantity pointer-type indicating gauge has its weak point, and electric current is bigger and unstable during work, the antivibration ability a little less than, its sensor resistance silk is sliding easily disconnected, rate of breakdown is higher.
(3) summary of the invention
The Automobile Digital oil level indicator that the purpose of this utility model is to provide a kind of easy to use, accurate measurement, is difficult for breaking down.
The utility model can be achieved through the following technical solutions above-mentioned purpose: the Automobile Digital oil level indicator mainly is made up of float, sensor, shrouding disc, connecting line, liquid crystal integrated package etc., float is fixed on the sensor, sensor and shrouding disc are spirally connected, and shrouding disc is connected by connecting line with the liquid crystal integrated package.
Can reach following good effect after adopting this technical scheme:
(1) oil level indicator adopts the pressure-type sensor, and the precision height is simple in structure.This structure has been avoided the general assembly (TW) of fuel tank, but utilizes the buoyancy of oil in the fuel tank, does not change the structure and the mounting means of fuel tank.
(2) replace traditional analog quantity pointer header, position, hole, the size of not changing meter panel of motor vehicle with the exact figure liquid crystal display.Easy for installation, accurate measurement, clear reading, degree of accuracy height.
(3) the high single-chip microcomputer of multiple functional integrated level is adopted in this product secondary instrument core, realizes the computing and the control of computer softwareization.Vibration proof, the anti-performance of jolting are good, and antijamming capability is strong, reliability height, long service life.
(4) description of drawings
Fig. 1 is the structural representation of the utility model Automobile Digital oil level indicator;
Fig. 2 is the electrical installation FB(flow block) of the utility model Automobile Digital oil level indicator.
(5) embodiment:
According to shown in Figure 1, the utility model Automobile Digital oil level indicator mainly contains compositions such as float 1, sensor 2, shrouding disc 3, liquid crystal integrated package 4 and connecting line 5, float 1 is fixed on the sensor 2, and sensor 2 is spirally connected with shrouding disc 3, and shrouding disc 3 is connected by connecting line 5 with liquid crystal integrated package 4.Float 1 passes to pressure transducer 2 with the buoyancy of the height generation of fuel tank liquid level, pressure transducer 2 is transformed into electric signal with pressure signal, because electric signal is very faint, amplify through shaping, send single-chip microcomputer again to parameter is carried out computing, the capacity that simultaneously weight of oil is transformed into oil flows to digital indicator.Thereby finish entire work process.
Claims (1)
1. Automobile Digital oil level indicator, mainly form by float (1), sensor (2), shrouding disc (3), liquid crystal integrated package (4) and connecting line (5), it is characterized in that: float (1) is fixed on the sensor (2), sensor (2) is spirally connected with shrouding disc (3), and shrouding disc (3) is connected by connecting line (5) with liquid crystal integrated package (4).
