Embodiment Construction

[0025] The present invention provides a screen, a roll-down mechanism and a control method thereof. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Such as figure 1 As shown, the present invention provides a roll-down mechanism of a screen, which includes a housing 200, an electric device, a curtain 100, a rotating shaft and a rolling tube 300, (the electric device and the rotating shaft are arranged in the housing 200, so the figure 1 not shown), the rotating shaft is movably connected in the housing 200, one end of the screen 100 is fixed in the housing 200, and the other end of the screen 100 is fixed on the roll tube 300, the The rotating shaft is driven to rotate by the electric device, and ...

Abstract

The invention discloses a screen, a down-rolled mechanism and a control method of the down-rolled mechanism. The down-rolled mechanism comprises a housing, an electric device, a curtain, a rotation axis and a reel pipe, wherein the rotation axis is movably connected into the housing; one end of the curtain is fixed in the housing; the other end of the curtain is fixed on the reel pipe; the rotation axis is driven by the electric device to rotate; the rotation axis is connected with the reel pipe through metal wires, so as to drive the reel pipe to reel upwards and downwards together with the rotation axis. When the curtain is taken up or put down, the electric device drives the rotation axis to rotate; the rotation axis drives the reel pipe to move up and down by rotation through the metal wires, so as to realizing the rolling up and rolling down of the curtain.

Description

technical field [0001] The invention relates to the technical field of screen control, in particular to a screen, a roll-down mechanism and a control method thereof. Background technique [0002] Projection screens are used in movies, offices, home theaters, large conferences, etc. to display images and video files. With the development of technology, various types of screens appear, especially super-large screens are sought after by the market, and the larger the screen, the more difficult it is to ensure the image quality. As the screen increases, its own force will be uneven, and the middle part of the screen will be uneven due to the influence of deflection, resulting in "water wave bending" or "V-shaped" and other phenomena. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above deficiencies in the prior art, the object of the present invention is to provide a screen and a roll-down mechani...
