Abstract
A projection device configured to provide multiple projection modes is provided. The projection device includes a housing module and a projection module. The housing module includes a display screen and multiple protective walls. The display screen includes a display curved surface. The projection module includes an optomechanical assembly and a light guide assembly. In a first projection mode, the optomechanical assembly projects an image light beam to the light guide assembly along a first axis. The light guide assembly projects the image light beam to the display curved surface along a second axis, where the first axis and the second axis are not parallel to each other. In a second projection mode, the light guide assembly is moved out of a transmission path of the image light beam, so that the image light beam is directly projected out of the projection device.
