Abstract

The invention discloses a head-up display, comprising a housing, a projector, a coincidence lens, a plurality of dust covers and a moving module. The housing is provided with an opening. The dust covers are coupled with the housing. The projector is arranged in the housing to provide image light beams. When the dust covers seal the opening, the coincidence lens is arranged in the housing. When the dust covers do not seal the opening, the coincidence lens can be moved out of the housing through the opening and moved to a transmission path of the light beams. The moving module is arranged in the housing and is coupled with the dust covers, so that the dust covers can move relative to the housing.

Description

technical field [0001] The invention relates to a display, in particular to a head-up display. Background technique [0002] A Head-Up Display (HUD for short) is used in an aircraft. In recent years, its application can also be found in civilian vehicles. The optical part of the head-up display includes a projector (Projector) and a composite mirror (Combiner). The projector can project the image of car information (such as speed, fuel level, light control, etc.) onto the stacking mirror. The superimposing mirror can overlap the scene outside the windshield with the car information image projected by the projector, so that the driver can see the desired information image without bowing his head or refocusing his eyes. [0003] According to the existing technology of the head-up display, the windshield of the car can be directly used as the stacking mirror. In addition, the superimposed mirror of the head-up display can also be independently produced, and related patents ...
