Angle adjustment module and projection device

Abstract

Disclosed are an angle adjustment module and a projection device. The angle adjustment module is suitable for the projection device, and includes a driving device and a lifting device. The driving device is disposed in the projection device, and includes a driving assembly and a transmission assembly. The lifting device includes a linkage supporting assembly and a lifting assembly. The driving assembly is disposed on a bottom cover of the projection device, and one end of the transmission assembly is connected to the driving assembly. The lifting assembly passes through an opening of the bottom cover of the projection device, and moves relative to the bottom cover in a direction perpendicular to the bottom cover to adjust an elevation angle of the projection device. The linkage supporting assembly is disposed in the projection device. The linkage supporting assembly is connected to one end of the lifting assembly located in the projection device and the other end of the transmission assembly respectively, to drive the lifting assembly to move relative to the bottom cover and provide static support for the lifting assembly.
