Problems solved by technology

[0003] The current car head-up display uses the principle of light refraction to project driving information on the front windshield. Usually, a dark reflective mirror needs to be pasted on the front windshield, which affects the driver's line of sight.

Embodiment Construction

[0014] see Figure 1 to Figure 3 , a preferred embodiment of the present invention provides a head-up display 100, which is applied in a car to provide the driver with driving information (such as vehicle speed, accelerator, fuel level, navigation information and side collision avoidance information, etc.). The head-up display 100 includes a projector 10 , a mirror 30 , a spherical mirror 50 and a base 70 . The projector 10 is installed in the base 70, and the reflecting mirror 30 and the spherical mirror 50 are rotatably connected to the base 70 through a first rotating structure 71 and a second rotating structure 73 respectively, so as to adjust the projector 10 , the relative angle between the reflecting mirror 30 and the spherical mirror 50, so that the driver can better check the driving information through the spherical mirror 50.

[0015] The base 70 includes a first mounting portion 75 and a second mounting portion 77, the first mounting portion 75 and the second moun...

Abstract

A head-up display is used for providing traffic information for a driver. The head-up display includes a projector, a reflector and a spherical mirror; the spherical mirror is a transparent concave mirror; a distance from the reflector to the spherical mirror is less than 1 * focal length of the spherical mirror; the projector is used to project an image of the traffic information to the reflector; after receiving the image of the traffic information, the reflector reflects the image of the traffic information to the spherical mirror; the spherical mirror is used for imaging the image of the traffic information reflected by the reflector. Because the spherical mirror is the transparent concave mirror, view of the driver cannot be affected when the driver looks over the traffic information through the spherical mirror; and the distance from the reflector to the spherical mirror is less than 1 * focal length of the spherical mirror of the spherical mirror, so that miniaturization of the head-up display can be achieved.

Description

technical field [0001] The invention relates to a head-up display, in particular to a vehicle head-up display. Background technique [0002] Head Up Display (HUD) for vehicles is to project driving information, such as the information displayed on the general instrument panel, onto the front windshield of the car, so that the driver can pay attention to the road conditions in front of the car through the front windshield while the car is driving. And the driving information can be obtained from the image projected on the front windshield by the head-up display, without the need to look down at the instrument panel, so as to increase driving safety. [0003] The current car head-up display uses the principle of light refraction to project driving information on the front windshield. Usually, a dark reflective mirror needs to be pasted on the front windshield, which affects the driver's sight. Contents of the invention [0004] In view of the above-mentioned deficiencies in...
