reflective screen device

Abstract

The invention discloses a reflecting screen device which comprises a base, a rotary mounting seat, a reflecting screen, a dustproof cover, and first, second and third rotation driving mechanisms. The rotary mounting seat is pivoted to the base around a first central axis perpendicular to the base. The first rotation driving mechanism is arranged on the base and drives the rotary mounting seat to rotate around the first central axis. The reflecting screen is pivoted to the rotary mounting seat around a second central axis perpendicular to the first central axis and is provided with a closing position closed at the base and a usage position unfolded from the base. The second rotation driving mechanism is arranged on the rotary mounting seat and drives the reflecting screen to rotate around the second central axis. The dustproof cover is pivoted to the base around a third central axis and is provided with a shielding position and an avoidance position. The dustproof cover at the shielding position shields the top part of the reflecting screen on the closed position. The dustproof cover at the avoidance position avoids the rotation of the reflecting screen between the closed position and the usage position. The third rotation driving mechanism is arranged on the base and drives the dustproof cover to rotate around the third central axis.

Description

technical field [0001] The invention relates to the technical field of electronic display equipment, in particular to a reflective screen device. Background technique [0002] Head-up display (full name: Heads Up Display, referred to as HUD) is to project and image driving information such as vehicle speed, fuel level, navigation, driving safety assistance, etc. required for driving on a suitable position in front of the driver for the driver to watch, so that the driver can always Keeping the head-up posture avoids safety hazards caused by looking down at the information displayed on the instrument, navigator or other driving assistance equipment, reduces the possibility of causing traffic accidents, and increases driving safety. [0003] As we all know, most of the commonly used head-up displays currently on the market mirror the driving information on the electronic screen by setting a reflective screen. [0004] Among them, the reflective screens and electronic screens ...

AI Technical Summary

Problems solved by technology

[0004] Among them, the reflective screen and electronic screen of some head-up displays are relatively fixed and cannot be adjusted. The reflective screen is difficult to meet the needs of different viewing angles of the driver. It is very inconvenient to use and has the disadvantage of complex structure.

[0005] In addition, some reflective screens of the head-up display need to be adjusted manually, which is not only very inconvenient to use, especially if manual adjustment is required during driving, it will affect driving safety, and its structure is also extremely complicated

At the same time, when this head-up display is not working, its reflective screen is exposed to the outside world, which not only makes the reflective screen easy to accumulate dust and other impurities and affects the reflective effect of the reflective screen, it cannot play the role of dustproof for the reflective screen, but also The external light will enter the eyes of the driver after being reflected by the reflective screen, causing dizziness and discomfort to the driver, and will also affect driving safety.
