US 2026/0270384 A1 · ANGLE ADJUSTMENT MODULE AND PROJECTION DEVICE

Abstract

An angle adjustment module is applicable to a projection device and includes a driving device and an elevating device including a linkage support assembly in the projection device and an elevating assembly. The driving device in the projection device includes a driving assembly on a bottom cover of the projection device and a transmission assembly connected to the driving assembly. The elevating assembly passes through an opening of the bottom cover of the projection device. The linkage support assembly is connected to one end of the elevating assembly in the projection device and the transmission assembly to drive the elevating assembly to move relative to the bottom cover to adjust a pitch angle of the projection device and provide a static support force for the elevating assembly. Therefore, the pitch angle of the projection device can be adjusted by the driving assembly without manually lifting the projection device.
