Description

Technical Field

[0001] The utility model relates to the technical field of HUD, in particular to a clamping fixture capable of quickly fixing the HUD. 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.

[0003] The installation position of the head-up display is determined by the body of the car. Different models of cars have different body structures, which leads to a variety of head-up display appearance structures. Generally speaking, a square head-up display cannot be installed on various models of cars. Therefore, most of the existing head-up displays have irregular structures. Therefore, during the assembly and testing of the head-up display, it is necessary to use a specific fixture to fix the head-up display to improve the stability and production efficiency of the product. However, most of the existing fixtures for fixing the head-up display are complex in design, inconvenient to use, and have insufficient clamping force, which causes the HUD to shake during assembly and affects the work efficiency. Therefore, it needs to be improved. Utility Model Content
