Embodiment Construction

[0042] figure 1 It is a perspective view of a portable projection screen device according to an embodiment of the present invention. figure 2 for figure 1 An exploded perspective view of the portable projection screen device of . Please refer to figure 1 and figure 2 , the portable projection screen device 100 of this embodiment includes a first board 110 , a second board 120 and a screen 130 . There is a gap between the second board body 120 and the first board body 110 and is suitable for expanding or closing on the first board body 110 . Two ends of the curtain 130 are respectively fixed on the first board body 110 and the second board body 120 . When the second plate body 120 is as figure 1 When it is closed on the first plate 110 as shown, the curtain 130 is folded between the first plate 110 and the second plate 120, and the bent part of the curtain 130 is accommodated in the first plate 110 and the second plate 120 intervals. Because there is a space between t...

Abstract

The invention discloses a portable projection cloth screen device which comprises first and second plate bodies, a cloth screen, spring plates and first and second chutes. Both ends of the cloth screen are respectively fixed on the first and second plate bodies. When the first and second plate bodies are closed, the cloth screen is folded between the first and second plate bodies and the bent part of the cloth screen is accommodated in a gap between the first and second plate bodies. The spring plates are abutted against the first and second plate bodies. When the first and second plate bodies are unfolded, the spring plates extend straightly so that the first and second plate bodies are fixedly expanded and the cloth screen is spread out. When the first and second plate bodies are started to be closed, the first and second plate bodies resist to the elastic forces of the spring plates to ensure the spring plates to be bent and the bent parts of the spring plates are accommodated in the gap between the first and second plate bodies. The first and second chutes are respectively fixed on the first and second plate bodies. The spring plates are positioned in the first and second chutes. Displacement spaces are provided for the spring plates by the first and second chutes.

Description

technical field [0001] The invention relates to a projection screen device, in particular to a portable projection screen device. Background technique [0002] A projection device is a display device for producing large-scale images. The imaging principle of the projection device is to convert the illumination beam generated by the light source into an image beam through a light valve, and then project the image beam onto a screen through a lens to form an image. With the advancement of projection technology and the reduction of manufacturing costs, the use of projection devices has gradually expanded from commercial use to home use. With the development trend of all kinds of electronic products towards high speed, high performance, light weight and short size, pico projector has gradually become the mainstream of personal digital market in the future. [0003] The miniature projector has a small volume, so that the user is easy to carry and can use it to project pictures ...
