Description

Technical Field

[0001] The utility model relates to the technical field of HUD, in particular to a novel 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

The ears at both ends of the HUD outer shell can be pressed and fixed by the end clamp mechanism 1, and the top of the HUD can be pressed and fixed by the top clamp mechanism 3. Through the mutual cooperation of the two, the clamping force on the HUD can be improved, thereby ensuring the stability of the placement of the HUD when assembling and testing it.

[0029] At the same time, the bottom of the rotating pressure plate 33 is in an outwardly convex arc structure. The rotating pressure plate 33 is designed to be in an arc structure that conforms to the shape of the HUD screen to avoid damaging the HUD. In addition, the two top clamp mechanisms 3 are respectively arranged close to the two ends of the HUD. The two top clamp mechanisms 3 can press and fix the top two ends of the HUD to ensure that the HUD is evenly stressed.

[0030] In order to further improve the stability of HUD clamping, in one embodiment, the end fixing blocks 13 (that is, the end clamp mechanism 1 is provided with two) are respectively installed at the two ends of one side of the end bearing seat 12; the end locking block 16 is arranged between the two end fixing blocks 13.
