Double-shaft rotating type reflecting screen device

Abstract

The invention discloses a double-shaft rotating type reflecting screen device which comprises a base, a rotating installation base, a first rotating drive mechanism, a rotating support, a reflecting screen and a second rotating drive mechanism. The rotating installation base is pivoted to the base around a first axis perpendicular to the base. The first rotating drive mechanism is arranged on the base. The rotating installation base is in transmission connection to the first rotating drive mechanism, and the first rotating drive mechanism enables the rotating installation base to rotate around the first axis. The rotating support is pivoted to the rotating installation base around a second axis perpendicular to the first axis. The reflecting screen is fixed to the rotating support. The reflecting screen is provided with a closed position closed on the base and a use position unfolded on the base. The second rotating drive mechanism is arranged on the rotating installation base. The rotating support is in transmission connection to the second rotating drive mechanism. The second rotating drive mechanism drives the rotating support to drive the reflecting screen to rotate between the closed position and the use position around the second axis.

Description

technical field [0001] The invention relates to the technical field of electronic display equipment, in particular to a dual-axis rotating 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. Among them, the reflective screens and electroni...

AI Technical Summary

Problems solved by technology

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.

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
