Abstract

The invention discloses an instrument cover of an instrument assembly, a design method thereof, an instrument assembly and a vehicle. The design method includes: making the driver's eye ellipse, inputting the position of the instrument panel and the instrument panel, the instrument panel is at least partly located on the upper side of the instrument panel to form the upper eaves of the instrument panel; selecting a point inside the upper eaves of the instrument panel as to be drawn The first focal point of the ellipse, pass the first focal point as the upper tangent of the eye ellipse, and the point of tangency between the upper tangent and the eye ellipse is the second focal point of the ellipse; with the first and second focal points determined in step 2 and the step The position of the instrument panel and instrument panel input in 1, draw an ellipse, select a part of the arc surface of the ellipse as the outer surface of the instrument cover, if the gap between the selected instrument cover and the instrument panel does not meet the requirements , return to step 2. The invention can prevent any light from entering human eyes after being reflected by the meter cover, and ensures that the driver can normally observe and read the readings displayed on the meter.

Description

technical field [0001] The invention relates to the field of vehicle design, in particular to an instrument cover of an instrument assembly, a design method thereof, an instrument assembly and a vehicle. Background technique [0002] The vehicle instrument assembly is used to provide the driver with the required information on the vehicle's operating parameters, and generally includes an instrument panel, an instrument panel cover, and an instrument panel on which the instrument panel and instrument panel are installed. The instrument cover is a transparent plastic part used to cover the instrument. Its function is to prevent dust and sundries from falling into the instrument panel, to ensure the normal operation of the instrument panel and for the driver to observe the readings of the instrument panel. However, the instrument cover usually adopts a curved surface structure, so reflection is a problem that often occurs in the instrument cover, that is, when any light source ...
