Abstract

The invention discloses a projection image rotating device and projection equipment. The projection image rotating device comprises a steering structure which is provided with a plurality of rotating reflecting surfaces which are used for reflecting projection images emitted by a projection assembly in sequence so as to rotate the projection images; and the emergent direction adjusting structure is provided with at least one adjusting reflecting surface, and the at least one adjusting reflecting surface reflects the projection image which is reflected and rotated by the plurality of rotating reflecting surfaces so as to adjust the projection plane position of the finally reflected projection image. According to the embodiment of the invention, the projection image emitted by the projection assembly is reflected through the reflecting surface in the steering structure, so that the rotation of the projection image is realized to adapt to projection contents with different size proportions, and the projection effect is better.

Description

technical field [0001] The present application relates to the field of projection technology, in particular to a projection image rotation device and projection equipment. Background technique [0002] At present, the devices usually connected to the projection components include but are not limited to TV set-top boxes, Windows system hosts / notebooks, Mac system hosts / notebooks, and home game console platforms. These devices are played in landscape by default, so the projection component is also set to landscape projection by default. However, with the rise and popularity of mobile phone applications, such as the popularity of short video applications, mobile phones will also need to be connected to projection components. At this time, the horizontal screen projection of the projection component cannot be well adapted to the screen of the mobile phone, and the screen of the mobile phone can only be zoomed and projected on the middle part of the horizontal screen, wasting th...
