Projection device

A projection device, adapted to be placed on a surface, wherein the projection device comprises a projection lens and a projection device housing, wherein

• the projection lens is connected to the projection device housing, and the projection lens is adapted to project a projection image toward a first direction;
• and
• the projection device housing comprises a main casing and a supporting assembly disposed on the main casing in a flipping manner, wherein
• the supporting assembly leans against the main casing when the projection device housing is located in a folded position, and
• the supporting assembly is flipped with respect to the main casing when the projection device housing is located in an unfolded position, and
• wherein the supporting assembly comprises a plurality of supporting members, the plurality of supporting members are sequentially arranged and are pivotally connected to one another end to end, and one of the plurality of supporting members is pivotally connected to the main casing, an inner contour of one of any adjacent two of the plurality of supporting members is complementary to an outer contour of the other one,
• the plurality of supporting members are received on a same plane and located below the main casing and are adapted to contact the surface together when the projection device housing is located in the folded position, and
• when the projection device housing is located in the unfolded position, the plurality of supporting members are flipped with respect to one another, and the one of the plurality of supporting members is adapted to contact the surface.
