Embodiment 1

[0023] A projection hanging curtain system. The projection hanging curtain system includes a track, a curtain 1, an automatic movement device and a cross bar 7. The track is composed of two sets of straight tracks as an upper track 3 and a vertical track 4. The automatic movement device includes a roller 6, an electric device 5 and a control device 4. The roller 6 can roll on the track, and under the control of the control device 4, the electric device 5 can provide power for the roller 6. Roller 6 is as hanging point and following hanging point. The middle stable point of hanging point is positioned on upper track 3 and vertical track 2. The upper hanging point and the lower hanging point have multiple stable points, and the stable points exist continuously on the track, that is, any point on the track can be used as a stable point. When the upper hanging point or the lower hanging point are located at different stable points, the The vertical inclination can be different. ...

Embodiment 2

[0026] A projection hanging curtain system, the projection hanging curtain system includes a track, a curtain 1, an automatic movement device and a cross bar 7, such as image 3 As shown, the track is a group of arc track 10, and the automatic movement device includes a roller 6, an electric device 5 and a control device 4. The roller 6 can roll on the track, and under the control of the control device 4, the electric device 5 can provide power for the roller 6. Roller 6 is as hanging point and following hanging point. The middle stable point of the hardpoint is located on track 3. The upper hanging point and the lower hanging point have multiple stable points, and the stable points exist continuously on the track, that is, any point on the track can be used as a stable point. When the upper hanging point is located at different stable points, the vertical inclination of the curtain 1 can be different. . The track includes a conductor, the conductor is connected with the po...

Embodiment 3

[0028] A projection hanging curtain system, which can be one of Embodiment 1 or Embodiment 2, the difference is that the projection hanging curtain system also includes a projector bracket, and the projector bracket includes a projector fixing plate 12 and a chassis 13, such as Figure 4 , Figure 5 As shown, the projector bracket is linked with the curtain 1 to keep the central line of the optical axis of the projector pointing to the center of the curtain 1. There are many ways to realize the linkage between the projector bracket and the screen 1. For example, the posture of the projector bracket is adjusted by detecting the posture of the screen 1 through the camera of the projector bracket; Input to the controller of the projector bracket, the current attitude of the curtain 1 is obtained by the sensor of the curtain 1, and the attitude of the curtain 1 is transmitted to the projector bracket, and the attitude of the projector bracket changes accordingly.

Abstract

At present, a hanging screen system is used by matching with a projector, light is projected on a screen of the hanging screen system by the projector, and images are displayed on the screen. An existing hanging screen system adopts a top hanging point manner, and a hanging screen is vertical. The projector is used in a family cinema step by step, some users like to lie when watching movies or a television, but an angle of the screen for watching the movies while lying is inappropriate. The invention discloses a projection hanging screen system which comprises top hanging points, bottom hanging points and the screen. A plurality of stabilizing points are arranged on the top hanging points, when the top hanging points are placed in different stabilizing points, vertical inclined angles of the screen can be different. The hanging points can be fixedly stopped in the stabilizing points, and each stabilizing point can be independent or existed in a continuous mode. When the top hanging points are stopped in different stabilizing points, the bottom hanging points change so that parallel translation is generated, and the vertical inclined angles of the screen can be different.

Description

technical field [0001] The invention relates to a projecting curtain system, in particular to a curtain system used in conjunction with a projector. Background technique [0002] At present, the hanging curtain system is used in conjunction with a projector, and the projector projects light onto the curtain of the hanging curtain system to display images on the curtain. The current hanging curtain system adopts the upper hanging point method, and the hanging curtain is vertically downward. Projectors are gradually used in home theaters, and some users like to lie down and watch movies and TV, but the angle of the screen is not suitable for lying down to watch movies. Contents of the invention [0003] The invention is a projection hanging curtain system, the inclination angle of the curtain can be changed to meet the different needs of users. [0004] A projection hanging system includes an upper hanging point, a lower hanging point and a curtain. The upper hanging point...
