Description

An adjustable HUD head-up display

Technical field

The utility model relates to the technical field of HUD head-up display, specifically an adjustable HUD head-up display.

Background technique

Head-up display is also called Head Up Display, or HUD for short. It is widely used in flight auxiliary instruments of aircraft and is now gradually becoming popular in automobiles. HUD is designed to improve car safety, allow drivers to focus on the road, and reduce the occurrence of accidents. The HUD market has developed rapidly in recent years, and more and more models have begun to be equipped with HUD products. New augmented reality head-up display device, referred to as AR-HUD. By combining cameras, radar and other equipment, the captured real road information is fed back to the windshield through the mirror. The imaging image seen by the driver is consistent with the real thing, and has dynamic effects related to the needs.

For HUD products, the height of the driver is different, and there are different requirements for the position of the HUD image. The projection position needs to be adjusted to ensure that the driver can see the image projected by the HUD from the best viewing angle. Traditional HUD products are fixed to the front of the instrument panel for projection display. However, such products cannot adapt to the needs of drivers of different heights. That is, when different drivers observe the HUD due to different viewing angles, the HUD imaging will be different. When it becomes lower or higher, it is inconvenient for the driver to observe vehicle information and road surface information, and it is easy to induce safety accidents.

In order to achieve the above object, the present utility model provides an adjustable HUD head-up display, which can solve the problems raised in the above background technology.

Utility model content

This utility model adopts the following technical solutions to achieve:

An adjustable HUD head-up display, including a HUD projection box, an adjustment component, and a windshield. The HUD projection box is installed inside the vehicle instrument panel.
