A kind of automobile fuel quantity detecting device

Abstract

The invention provides an oil level detection device for a car. The oil level detection device comprises an oil floater oil measuring unit, wherein a buoy of an oil floater in the oil floater oil measuring unit floats on the oil surface of an oil tank. The oil level detection device is also provided with a mesh for covering the buoy of the oil floater; an oil floater oil measuring unit is arranged at the top part of the mesh and is sealed; the front surface and the back surface of the mesh are sealed, the left side surface and the right side surface of the mesh are provided with mesh grids, and the front surface and the back surface of the mesh are vertical to the driving direction of the car; the left side surface and the right side surface of the mesh are parallel to the driving direction of the car; the mesh grids comprise through holes for making oil enter the mesh; the bottom part of the mesh is fixed at the bottom part of the oil tank. The oil level detection device provided by the invention has the advantages that linear change of the oil level measurement values is realized, the back and forth swinging range of a pointer of an oil meter is smaller, and under the condition without changing the existing oil level measuring equipment of the car, the oil level measurement value is more accurate, so that convenience is brought for a driver to master the information of the remaining oil level in the oil tank more clearly.

Description

technical field [0001] The invention relates to the technical field of automobile electronics, in particular to an automobile oil quantity detection device. Background technique [0002] During the driving process of the car, the driver needs to judge the remaining fuel in the fuel tank of the car in order to better decide whether to refuel the car. figure 1 As shown, it includes a sliding rheostat 6, an oil gauge 5, and an oil float 4. The oil gauge is equivalent to an ammeter, and the fuel quantity information of the fuel tank is obtained from the scale indicated by the pointer of the fuel gauge. [0003] This type of oil quantity detection method has the following defects: [0004] a. When the car is driving on a bumpy road, the oil in the fuel tank fluctuates violently. At this time, the buoy 2 of the oil float will also fluctuate with the oil surface. When the fluctuation range of the buoy of the oil float is too large, it is easy to cause oil volume The pointer of th...

AI Technical Summary

Problems solved by technology

[0004] a. When the car is driving on a bumpy road, the oil in the fuel tank fluctuates violently. At this time, the buoy 2 of the oil float will also fluctuate with the oil surface. When the fluctuation range of the buoy of the oil float is too large, it is easy to cause oil volume The pointer of the gauge swings rapidly and in a wide range, the driver will not be able to judge the fuel volume in the fuel tank, and other data calculated based on the fuel volume value in the fuel tank will also be wrong

[0005] b. When the oil in the fuel tank collides with the wall of the fuel tank and rebounds and hits the oil float, the oil float is pressed down, resulting in a low measured value of the oil volume in the fuel tank

[0006] c. When the car accelerates or decelerates, due to the effect of inertia, the entire oil level is tilted forward or backward, which raises or lowers the oil float, resulting in a high or low measured value of the oil quantity.
