AI Technical Summary

Technical Problem

The enclosed housing structure of traditional automotive head-up displays results in insufficient heat dissipation efficiency, which affects the imaging accuracy of optical components and the reliability of the equipment under high-temperature conditions.

Method used

The design employs a detachable first and second housing. The outer surface of the second housing is equipped with heat dissipation fins, which, combined with a light shield and a cooling fan, enhance heat dissipation efficiency. Light imaging is achieved through a reflective component and an exit window.

Benefits of technology

It improves the heat dissipation efficiency of the display module, prevents overheating, enhances the imaging accuracy and equipment reliability of optical components, and simplifies the maintenance process.

Abstract

This utility model discloses an automotive head-up display (HUD), comprising a first housing, a second housing, a display module, and a light shield. The first housing has an emission window and a reflective component inside. The outer surface of the second housing has heat dissipation fins. The first and second housings are detachably connected. The display module is installed inside the second housing, and light from the display module passes through the reflective component and exits through the emission window. The light shield is installed on the light-emitting side of the display module and blocks external heat radiation from being transferred to the display module. The detachable connection between the first and second housings separates the reflective component and the display module, facilitating individual disassembly of either the display module or the reflective component during maintenance, thus improving maintenance efficiency. When the display module generates heat during operation, it transfers heat to the second housing; the heat dissipation fins enhance the heat dissipation efficiency of the second housing. The second housing is made of aluminum alloy, which offers high heat dissipation efficiency.
