Problems solved by technology

This type of oil detection method has the following defects: a. The oil float is greatly affected by the fluctuation of the oil level, which causes the pointer of the oil gauge to fluctuate greatly back and forth, and the measurement is inaccurate; b. The measurement accuracy of the sliding rheostat is low and the sensitivity is not high. Therefore, the current There are technologies to be further improved

Abstract

The invention provides a capacitive oil mass measuring device. The capacitive oil mass measuring device comprises a capacitive piston structure composed of a cuboid insulating shell, a capacitive upper polar plate, soft springs and a capacitive lower polar plate, and a capacitive measuring unit connected with the capacitive upper polar plate and the capacitive lower polar plate. The two side faces, parallel to the vehicle driving direction, of the capacitive upper polar plate are connected with the soft springs. The two inner walls, parallel to the vehicle driving direction, of the cuboid insulating shell are provided with symmetric grooves for installation of the soft springs. The grooves and the soft springs are matched to enable the capacitive upper polar plate and the inner wall of the cuboid insulating shell to be vertically connected in a sliding mode, the capacitive upper polar plate serves as a floating piston of the capacitive piston structure, and the capacitive lower polar plate is symmetric with the capacitance upper polar plate and is attached to the bottom of an oil tank. The oil mass measuring precision is greatly improved, and the change condition of the oil mass is convenient to monitor in real time.

Description

technical field [0001] The invention relates to the technical field of automobile oil volume measurement, in particular to a capacitive oil volume measurement 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, an oil gauge, and an oil float. The oil gauge is equivalent to an ammeter, and the fuel quantity information of the fuel tank is obtained from the scale pointed by the pointer of the fuel gauge. This type of oil detection method has the following defects: a. The oil float is greatly affected by the fluctuation of the oil level, which causes the oil gauge pointer to fluctuate greatly back and forth, and the measurement is inaccurate; b. The sliding rheostat has low measurement accuracy and low sensitivity. Therefore, the current There is technology to be further improve...
