Description
Technical Field
The utility model relates to the technical field of automobile structural parameter measurement, in particular to a portable automobile approach angle and departure angle measuring device.
Background
The approach angle refers to the angle between the tangent line of the front end protruding point and the ground when the automobile is fully loaded and stationary. The departure angle is the included angle between the tangent line led by the protruding point at the rear end of the automobile to the rear wheel and the ground when the automobile is fully loaded and is stationary. The larger the approach angle and the departure angle, the less likely the vehicle front end cannot pass through because of touching the ground. Conversely, the smaller the approach angle and the departure angle, the more likely the vehicle front end will not pass through because of touching the ground.
Because the approach angle and the departure angle belong to three-dimensional space dimensions, the approach angle and the departure angle cannot be directly measured by an angle ruler like the measurement of plane angles. At present, when the approach angle and the departure angle are measured, the measurement is mainly carried out by taking a large plane plate as an auxiliary tool: the flat surface is brought against the two tire surfaces and the lowest point of the front or rear lower part of the vehicle, and then the acute angle formed by the flat surface and the ground is measured. The measuring method is simpler, but for vehicles with different external dimensions, plane plates with different sizes are needed; secondly, the method is influenced by the thickness of the plane plate, when the plane plate is thicker, a more accurate tangent plane cannot be found, and the thicker the plate is, the worse the accuracy is; when the flat plate is thin, the flat plate is easily deformed, and measurement cannot be performed.
