Description

Technical Field

[0001] The utility model relates to the technical field of HUD, in particular to a HUD clamping and fixing device. Background Art

[0002] Head-up display (HUD) technology refers to the use of reflective optical design to project light emitted by an image source onto an imaging window (imaging board, windshield, etc.). This allows the driver to directly see information such as speed and navigation without having to lower his head while observing the real environment outside the windshield. This prevents the driver from being distracted by looking down at the dashboard or central control screen while driving, thereby improving driving safety and providing a better driving experience.

However, the existing fixtures for fixing the head-up display are mostly complex in design, inconvenient to use, and have insufficient clamping force, which causes the HUD to shake during assembly and affects work efficiency. Therefore, it needs to be improved. Utility Model Content
