Patent ID: 8007117

Claim:
An assembling mechanism for assembling a lens module of a projector to an optical engine base of the projector, the assembling mechanism comprising: a supporting stage adapted to be fixed to the optical engine base; a supporting flange adapted to be fixed to the lens module; at least one first fastener adapted to be fixed to the optical engine base; at least one second fastener selectively engaged with the first fastener, and adapted to be disposed on the lens module around an axis; a first electrical connector fixed to the optical engine base; and a second electrical connector selectively coupled with the first electrical connector and adapted to be disposed on the lens module, wherein the displacement of the supporting flange along the axis and the rotation of the supporting flange about the axis relative to the supporting stage are limited, and the first electrical connector is coupled with the second electrical connector, when the supporting flange is against the supporting stage, and then the second fastener rotates relatively to the first fastener about the axis and is engaged with the first fastener.
