Description

Technical Field

[0001] The utility model relates to the technical field of HUD, in particular to a quick clamping fixture for 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 structure of the head-up display is mostly irregular in shape. Therefore, during the assembly and testing of the head-up display, a specific fixture must be used to fix the head-up display to improve the stability of the product and production efficiency. 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

During the rotation of the first push-pull rod 142, the protrusion 148 on one side of the first push-pull rod 142 will gradually contact the two second rotating arms 147 and exert downward pressure thereon, thereby driving the second rotating arms 147 to rotate. When the second rotating arms 147 rotate, the first clamping plate 13 will be pressed downward. When the first rotating rod is rotated to a vertical state, the first clamping plate 13 will press and fix the ear of the HUD outer shell, thereby completing the pressing process of the HUD end.

[0035] In one embodiment, a second through hole is further provided at the top of the first clamping block 146, and a first bolt 149 is further installed in the second through hole; the other end of the first clamping plate 13 is connected to the first bolt 149, and one end of the first clamping plate 13 extending above the first support seat 11 is further provided with two clamping rods 150.
