Projection position adjusting device, projection equipment and vehicle

Abstract

The invention relates to a position adjusting device and discloses a projection position adjusting device. The device comprises areflecting mirror (1), a driving device (2) and a control module, wherein the reflecting mirror (1) is connected with the driving device (2) through a transmission mechanism (3); the control module is electrically connected with the driving device (2) so thatthe drivingdevice (2) drives the reflecting mirror (1) to rotate to a set angle so as to adjust a projection position of an image; and the control module is electrically connected with an image projection lightsource so as to control a picture size of the image projection light source and a luminous flux reflected by the reflecting mirror (1). The invention further discloses projection equipment comprisingthe projection position adjusting device and a vehicle. According to the projection position adjusting device, a position of a projection image can be changed, distortion of the projection image cannot be generated, and accuracy of information transmitted by the projection image can be guaranteed.

Description

technical field [0001] The present invention relates to a position adjustment device, in particular to a projection position adjustment device. Furthermore, the present invention also relates to a projection device and a vehicle. Background technique [0002] Nowadays, the projection display technology used in automobiles is becoming more and more indispensable. It can facilitate drivers to understand vehicle information and improve driving safety. At present, the commonly used projection display technologies include DLP, HUD, etc., but due to the limitation of the deflection angle of the lens or MEMS micromirror, the field of view that can be output by traditional vehicle projection is generally not large. [0003] Taking HUD as an example, the most obvious manifestation of the insufficient field of view is that the projected display range is small, which can only be displayed on the windshield directly in front of the driver, and the display area is small, and the informa...

AI Technical Summary

Problems solved by technology

[0004] For the road surface projection outside the car, the biggest defect is that the display area is small and the display position is fixed. In order to realize the projection display around the car body, it is often necessary to install multiple projection devices linked to cover the entire area or realize all functions. The cost is high, and the differences between different devices The inconsistency of the performance between them will also lead to poor display effect. At the same time, the angle of optical output of a single device is fixed, resulting in a fixed installation position, which may affect the appearance of the vehicle.
