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.

Projection device

A projector, including a body, a light source, a light valve, a projection lens, and a lens adjustment module, is provided. The light source and the light valve are disposed in the body, and the projection lens is movably disposed on the body. The lens adjustment module includes a driven structure connected to the projection lens, a guiding member and a rotating member connected to the guiding member. The guiding member is disposed on the body to be rotatable along an axis of rotation and has a closed ring guiding rail. The driven structure is slidably disposed at the closed ring guiding rail and is configured to move relative to the guiding member along a closed ring path defined by the closed ring guiding rail. A normal direction of a surface where the closed ring path is located is not parallel to the axis of rotation.

Projector and lens adjustment module

Provided are a projector and a lens adjusting module. The projector includes a main body, a light source disposed on the main body and providing an illumination beam, a light valve disposed on the main body and converting the illumination beam into an image beam, a projection lens movably disposed on the main body in a moving direction and projecting the image beam, and the lens adjusting module. The lens adjusting module includes a driven member connected to the projection lens and having a limiting flange, a limiting structure connected to the main body, and a rotating member screwed to the driven member and rotating to drive the driven member and the projection lens to move in a moving direction. The limiting structure is adapted to stop the limiting flange to limit a movement range of the driven member in the moving direction.

Projector and lens adjusting module

A projector includes an optical engine module, a projection lens module, a heat dissipation module, and a laser module. The laser module includes a positioning member and a laser unit fixed to the positioning member, wherein a positioning member includes a main plate portion and two shoulder portions, the main plate portion includes a first upper surface and a first lower surface opposite to each other, a first front surface and a first rear surface opposite to each other, and a first left side surface and a first right side surface opposite to each other, and the two shoulder portions extend on a plane of the first upper surface from the first left side surface and the first right side surface of the main plate portion, respectively. A laser module is also provided.
