Abstract

The invention provides a projection screen device. The projection screen device comprises a supporting and driving mechanism and a screen component. The screen component comprises a first curtain andtwo flexible reels. The reels are connected to two opposite ends of the first curtain, and are movably connected to the supporting and driving mechanism. The supporting and driving mechanism comprisesa support column, two support arms, a first driving component and two second driving components. The support arms are connected to two opposite ends of the support column movably. The first driving component is arranged at the space between the two support arms. The second driving components are connected to one sides of the support arms, and are used for driving the two reels to bend radially atthe same time. The projection screen device has the advantages that the first driving component drives the support arms and the reels to move along the extension direction of the support column to achieve area change of the first curtain, and the second driving components drive the two reels to bend radially at the same time to change the first curtain from a plane to a hook face or from the hookface to the plane, so that the technical problem of incapability of changing flat and curved states and areas of curtains of projection screen devices is solved, and user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of projection auxiliary equipment, and more specifically relates to a projection screen device. Background technique [0002] With the development of projection technology, projectors are widely used in cinemas, offices, classrooms, weddings and other occasions to display images and video files. In order to achieve better display effects, projectors generally require a projection screen device for use. [0003] At present, because the material of the curtain in the projection screen device is relatively soft, the shape of the curtain is determined by the shape of its support. For example, if the curtain is fixed on the wall, the shape of the curtain can only be flat due to the influence of the wall; in addition, During the use of the existing projection screen device, the size of the screen is fixed, that is, the area of ​​the screen cannot be adjusted according to the wishes of the user. Therefore, for the...
