[0001] This utility model belongs to the field of HUD head-up display devices, specifically, it relates to an adjustable automotive HUD head-up display device. Background Technology
[0002] Head-up display (HUD), also known as a parallel display system, is a driver-centric, blind-operated, multi-functional instrument panel. Its function is to project important driving information such as speed and navigation onto the windshield in front of the driver, allowing the driver to see important driving information such as speed and navigation without looking down or turning their head. With the rapid development of technology, the use of HUD in automobiles has gradually increased. It mainly uses a projection display module to display virtual images through multiple spherical mirrors on the inside of the windshield so that the driver can view the current vehicle information.
[0003] When a head-up display (HUD) is in use, it is usually fixedly installed in a car, which makes the angle of the HUD fixed. However, different users have different usage habits, making it difficult to adjust the HUD according to individual needs, which reduces the comfort of the user. In view of this, this utility model is proposed. Utility Model Content
