Problems solved by technology

However, when there is strong light (such as sunlight) outside the vehicle, the external light can pass through the windshield to reach the curved mirror, and then converge on the focal plane of the curved mirror, causing the converged light spots to burn out the image source, or even Accident caused by vehicle fire
see figure 1 As shown, when the sun is at a certain angle or position, sunlight can pass through the windshield and directly enter the curved mirror 1 of the HUD, making the light converge near the image source 2, which may burn out the image source 2

Abstract

The invention provides head-up display equipment. The head-up display equipment comprises an image source, a shading structure and one or more reflecting elements, wherein the image source is used foremitting imaging light and emitting the imaging light to the reflecting element; the reflecting element is arranged on a propagation path of the imaging light and is used for reflecting the imaging light and reflecting the imaging light to an external imaging device; and the shading structure is arranged at a light outlet, the image source or at least one reflecting element, and is used for blocking the light transmitted to the image source or the reflecting element when receiving the shading signal. According to the head-up display equipment provided by the embodiment of the invention, the shading structure is arranged in the head-up display body; under normal conditions, the shading structure does not affect normal imaging of the head-up display equipment; when shading is needed, the shading structure can block an external light path or change an imaging light path to prevent external light from directly entering the image source, and the image source can be prevented from being burnt out due to too strong external light.

Description

technical field [0001] The present invention relates to the technical field of heads-up displays, in particular to a head-up display device. Background technique [0002] HUD (head up display, head-up display) can be imaged (virtual image) by using the windshield of the car, so that the head-up display can project an image containing instrument panel information, and the driver can watch the real environment outside the windshield at the same time. The imaging of the head-up display can avoid the distraction caused by the driver looking down at the dashboard during driving, which can improve the driving safety factor and bring a better driving experience. [0003] There is an image source inside the traditional HUD. When strong external light is incident on the image source, the temperature of the image source will rise, which may affect the normal operation of the image source. In addition, HUDs generally have curved mirrors, and the image source is close to the focal plan...
