Field of view test bench for head-up display

Abstract

The invention relates to a field of view test bench for a head-up display. The field of view test bench is composed of a parallel light pipe, a platform, a head-up display bracket and an eye positionframe. The bottom of the parallel light pipe may be fixedly connected with the platform. An adjustable mechanism is designed between the head-up display bracket and the platform. After a head-up display is mounted on the bracket, the adjustable mechanism can be adopted to make the light axis of the head-up display to be parallel to the light axis of the parallel light pipe. The flip eye position frame can assist a tester in accurately positioning eye positions. The beneficial effects are that the head-up display and the parallel light pipe are integrated on the field of view test bench for thehead-up display so as to be able to move as a whole, the head-up display and the parallel light pipe are adjusted horizontally, the head-up display bracket is fixed on the platform and through the adjustment of four ball screws, the positions of the head-up display in the vertical direction as well as in azimuth and pitch are ensured, so that the head-up display is aligned with the light axis ofthe parallel light pipe, the operation is convenient, and the test preparation time is saved.

Description

technical field [0001] The invention belongs to the technical field of head-up display visual field range detection, and relates to a head-up display visual field test platform, which can integrate a head-up display and a collimator on one platform. Background technique [0002] The field of view is an important indicator of HUD, and it is often one of the essential inspection items when conducting acceptance tests. The head-up display field of view test bench is to solve the problem of the field of view range test of the head-up display. Although the traditional field of view test method is to test the field of view through the collimator, the head-up display and its fixed tooling should be placed on an adjustable lifting platform. The tooling and the lifting platform are not relatively fixed. The operation of adjusting the optical axis is cumbersome; the eye distance of the testers observing the HUD is only a human judgment and cannot be guaranteed as required. Contents...
