Head up display device

Abstract

The invention relates to a head up display device. The head up display device comprises a reflection frame and a concave imaging mirror frame; a reflector is arranged on the reflection frame provided with an accommodation space, and a display is arranged in the accommodation space and corresponds to the reflector to enable reflection of a solid image of the display so as to generate a reflection image; a concave imaging mirror is arranged on the concave imaging mirror frame, one surface of the concave imaging mirror is provided with an anti-reflection coating, and the other surface of the concave imaging mirror is provided with a semi-permeable coating for receiving the reflection image of the reflector to display a magnified distant virtual image. Therefore, the head up display device has the advantages that the device is small in space occupancy and does not need to be set up in a vehicle-machine system in a vehicle, an existing display device can be applied directly for generating the magnified distant virtual image, and the device is easy for users to mount and use by themselves.

Description

technical field [0001] The invention relates to a device for a driver to observe vehicle information by looking up, in particular to a simple head-up display device. Background technique [0002] Head Up Display (HUD), originally a flight aid instrument commonly used in aviation tools, is named Head Up, which means that pilots can see the important information they need on the HUD without bowing their heads. [0003] The head-up display device first appeared on military aircraft, mainly to reduce the frequency of the pilot needing to look down at the instrument panel, to avoid interruption of attention and loss of state awareness, because of the convenience of the head-up display device and the ability to effectively improve flight Safety has led to the installation of civil aviation aircraft one after another. At present, there are also automobile companies using similar devices as a marketing method to attract customers. [0004] However, since various head-up display dev...

Problems solved by technology

[0004] However, since various head-up display devices are more and more widely used in vehicles, the market share of products is gradually increasing. The existing head-up display device products can be roughly divided into two categories, one is to display images directly through the display, and Directly project the image of the display on the windshield. Although the utilization rate of light is high, it can display a clear image, but the viewing distance will be obviously insufficient; viewing distance, but requires a brighter light source to compensate for the loss of brightness due to multiple optics

Furthermore, although the former is easy to install by itself, the optical effect is not ideal. Although the optical effect of the latter is better, but due to the large number of optical components, the volume becomes huge. If you want to use it, most of them must be embedded in the car system of the vehicle. , making it difficult for the driver to install the
