Embodiment Construction

[0025] Embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] The invention utilizes the principle that the relative spatial position relationship between the HUD design eye position and the center point of the mounting bracket is fixed, and determines the spatial position of the reference eye position through a bent metal plate mounted on the mounting bracket.

[0027] Firstly, according to the relative distance between the design eye position of the hoisting HUD and the center point of the hoisting HUD mounting bracket in the direction perpendicular to the plane of the mounting bracket, a rigid bent metal plate is designed and processed. The metal plate is divided into a fixed section, a transition There are three sections of connection section and observation section, the fixed section and the observation sectio...

Abstract

The invention provides a device and a method for rapidly determining the design eye position of a hoisting head-up display. The device is a rigid bending metal plate, and three mounting holes and oneobservation hole are formed in the metal plate. The space position between the three mounting holes and the observation hole reflects that the space position between a mounting bracket and the designeye position, so that after a positioning metal plate is arranged on the mounting bracket, the observation hole position on the positioning plate is the position of the actual design eye position, andthe design eye position can be rapidly positioned. The space position of the head-up display design eye position can be determined precisely and rapidly by utilizing the relatively fixed space position relation. The error fluctuation of finding the design eye position at each time by the traditional method is avoided; and compared with the traditional method, and the positioning method is more accurate and is stable and reliable in positioning precision at each time.

Description

technical field [0001] The invention relates to the determination of the design eye position during the test of a hoisting head-up display, in particular to a device and method for quickly determining the design eye position of a hoisting head-up display. Background technique [0002] When testing the optical performance of the HUD, the observation device needs to be installed at the design eye position, which is a spatial position with a certain distance from the center point of the HUD combined mirror assembly. Only at this position can the observation and measurement of the optical performance of the HUD be accurate. of. The traditional method is to fix the head-up display debugging bench on a horizontal marble table, install the head-up display mounting bracket on the debugging bench, then fix the head-up display projection assembly and the combination mirror assembly, and then find the center of the head-up display combination mirror assembly, and then Using a ruler, m...
