Telescopic platform and projection device

Abstract

The disclosure discloses a telescopic platform and a projection device, and belongs to the technical field of projection. The telescopic platform comprises a support seat, a driving device is arranged on the support seat; a moving table is movably arranged on the support seat and connected with the driving device, and is used for carrying a projection host of the projection device and moving the projection host to an extended position when the projection host is turned on and moving the projection host to a retracted position when the projection host is turned off; in the driving device, the output end of a driving motor is connected with a driving piece, the driving piece is connected with a transmission piece, the transmission piece is connected with the moving table, so that the moving table is switched between the extended position and the retracted position through the transmission piece; the connecting part of the driving piece and the transmission piece is provided with an elastic buffer mechanism, so that the elastic connection between the driving piece and the transmission piece is realized through the elastic buffer mechanism. The elastic buffer mechanism plays a buffering role to reduce the extrusion force suffered by the user's fingers in a short time when the fingers are clamped, so that the user can timely pull out the fingers before being clamped, and the use experience of the telescopic platform is improved.
