Abstract

The application discloses a projection device and a method for adjusting the attitude of a projection lens thereof, belonging to the field of projection display. Since the projection lens in the projection device is movably connected to the housing of the host, and the attitude data acquisition component in the projection device can automatically acquire the actual attitude data of the projection lens. When the processor determines that the actual attitude data sent by the attitude data acquisition component is different from the preset attitude data, it can send an adjustment signal to the lens driving component, so that the lens driving component can automatically adjust the attitude of the projection lens to the attitude indicated by the preset attitude data . Therefore, there is no need for the user to adjust the projection position of the projection lens by manually adjusting the placement state of the host, which improves the efficiency and reliability of the attitude adjustment of the projection lens, thereby improving the efficiency and reliability of the projection position adjustment of the projection lens.

Description

technical field [0001] The present application relates to the field of projection display, in particular to a projection device and a method for adjusting the attitude of a projection lens thereof. Background technique [0002] Currently, a projection device may include a host, a projection screen, and a projection lens fixedly connected to the casing of the host, and the projection lens is used to project images onto the projection screen. If the user accidentally bumps into the host and the placement of the host changes, the posture of the projection lens will also change, which will cause the projection position of the image on the projection screen to change, thereby affecting the display effect of the image. Since the projection lens is fixedly connected to the housing of the host, the user needs to manually adjust the placement of the host to adjust the projection position of the projection lens, thereby ensuring that the image projected by the projection lens is locat...
