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.
本发明涉及位置调节装置,公开了一种投影位置调节装置,包括反射镜(1)、驱动装置(2)和控制模块,所述反射镜(1)和所述驱动装置(2)通过传动机构(3)相连,所述控制模块与所述驱动装置(2)电连接,以能够通过所述驱动装置(2)带动所述反射镜(1)旋转到设定角度调节图像的投影位置,所述控制模块与图像投影光源电连接,以能够控制所述图像投影光源的画幅尺寸以及经过所述反射镜(1)反射的光通量。本发明还公开了一种包括上述投影位置调节装置的投影设备和车辆。本发明的投影位置调节装置能够实现投影图像位置的改变,同时不会产生投影图像的畸变,能够保证投影图像所传递信息的准确性。
