Description

Technical Field

[0001] The utility model relates to a head-up display system for an automobile, in particular to a hemispherical head simplified fixing mechanism for an on-board curved mirror. Background Art

[0002] With the development of the automobile industry, the vehicle-mounted HUD head-up display has gradually become popular. The head-up display realizes image height adjustment by rotating the curved surface. The curved mirror rotating mirror fixing mechanism in the prior art usually has a fixing piece on the left and right, and a mounting hole is opened on both sides of the shell outside the curved mirror. The two fixing pieces are respectively connected to the two side walls with the mounting holes. The structure usually needs to be respectively provided with a screen bracket for fixing the curved mirror on both sides of the curved mirror. The overall structure is relatively complex, and when the curved mirror needs to be disassembled and replaced, it is very troublesome to replace it due to the large number of fixing pieces. In addition, too many fixing pieces will also cause the fit to be too tight, so that the surface of the curved mirror will be deformed by force, resulting in an increase in imaging error. If the fit is too tight, when it encounters external force vibration or impact, the stress received will also increase significantly, and the shaking of the curved mirror during rotation will also be more obvious, and the rotation will be unstable. After a long time, it is easy to cause damage to the curved mirror, resulting in a short service life. Therefore, it is necessary to design a simplified hemispherical head fixing mechanism for a vehicle-mounted curved mirror with a small number of parts, a simple structure, and stable rotation.
