Description

Portable Dome Projection Curtain

This creation is about a dome projection curtain, especially a dome projection curtain structure that is easy to carry and can be assembled quickly.

People mainly use sight and hearing as their main senses to receive affairs and information from the external environment. Nowadays, in various fields such as art, audio-visual, games, teaching, and other fields, in order to make people fully immerse in absorbing feelings, they are not immune to other things. Therefore, the immersion theory (also known as immersion experience) is used to guide people into an immersive state. The immersion theory mainly uses the sense of presence to make people feel deep into the environment and induce people's interest and curiosity. , and enable people to improve their concentration independently. This immersion theory generally adopts VR technology (virtual reality) or is presented by projection on a spherical screen.

The VR technology needs to use multiple sensors to perceive human movements, and use a computer to perform a large amount of computing processing to present images of the virtual environment to users. The equipment costs a lot and it is difficult to popularize the public.

The spherical screen projection system combines a plurality of rods into a plurality of triangular brackets, and pushes and stacks the triangular brackets to assemble a spherical bracket structure B (as shown in Figure 1), and then hangs a spherical screen. On the ball support structure B, it is used with projection equipment. When the user is in the ball support structure B, the image projected by the ball screen is relative to the user's surroundings. Bring a sense of presence.

However, the spherical support structure B requires the joint efforts of many people to be able to assemble, which is time-consuming and labor-intensive, and cannot be easily changed after the erection is completed. reassemble.

Therefore, how to provide a projection screen structure or device that can be used in the immersion theory and is easy to carry and quickly assemble is the direction that the creator of this creation is eager to research and improve.

The main purpose of this creation is to provide a portable dome projection screen, which includes a plurality of bases, a plurality of rod bodies and a dome fixing plate, one end of the rod bodies can be fixed on each base respectively, the The other end of the rod body can be fixed on the dome fixing plate, so as to form a dome structure. The dome structure is covered with at least one projection cloth for projection by the projection equipment. When the top projection screen does not need to be used or needs to be moved to other places for use, the projection screen can be removed, and the bases, rods and the dome fixed plate can be quickly disassembled for storage or carried in bags, so as to achieve Provide a dome projection screen structure that is easy to carry and quick to assemble.

In order to achieve the above-mentioned purpose, the present invention provides a portable dome projection screen, which at least comprises: a plurality of bases; It is fitted and fixed on each base; a dome fixing plate, the dome fixing plate can be inserted and fitted and fixed with the top ends of the rod bodies, and forms a dome structure with the rod bodies; and, At least one projection cloth is draped on the inner or outer side of the dome structure, and the projection cloth is elastic; wherein, the end of the rod body is respectively provided with a latch, the top and bottom ends of the rod body are , which is inserted, fitted and fixed on the dome fixing plate and the base by the pins.

According to the above-mentioned main features, wherein the base is a tripod, and the tripod has at least a lifting structure.

According to the aforementioned main features, wherein the rod system is a fiberglass rod.

According to the above-mentioned main features, a frame rod can be respectively provided between the base and the base to fix the distance between the bases.

According to the aforementioned secondary feature, wherein the dome projection screen further includes at least one steering fixing seat, the steering fixing seat is movably sleeved on a frame rod, and can be inserted into the bottom end of a rod body for fitting and fixing .

According to the above-mentioned main features, the dome projection screen further includes a rain cover, and the rain cover is draped and sleeved on the dome structure and is opposite to the outside of the projection cloth.

Figure 4 is a schematic diagram of the combination of the rod body and the dome fixing plate of this creation.

In order to achieve the above or other purposes and effects, the technical means and The structure, the preferred embodiment of the present creation is described in detail, and its features and functions are as follows, so that I can fully understand it.

Please refer to Figures 2 to 4. Figure 2 is a schematic structural diagram of a portable dome projection screen of the present creation; Figure 3 is another structural schematic diagram of a portable dome projection screen of the present creation, which shows The frame rod of the dome projection curtain; Figure 4 is a schematic diagram of the combination of the rod body and the dome fixing plate.

As shown in these figures, the present creation system provides a portable dome projection screen, which at least includes: a plurality of bases 10, a plurality of rod bodies 20 and a dome fixing plate 30, the rod body 20 has a bendable arc Elastic force, preferably, the rods 20 are made of glass fiber rods, the bottom ends of the rods 20 can be inserted and fitted on the bases 10 respectively, and the tops of the rods 20 can be inserted It is fitted and fixed on the dome fixing plate 30 to form a dome structure. The projection cloth 40 has elasticity and is stretched and covered on the dome structure 30 (as shown in FIG. 2 ). 360-degree panorama can be used for projection equipment projection, and when the dome projection screen of this creation is not in use, or needs to be moved to other places for use, the projection cloth 40 can be easily removed first, and then the dome projection screen can be easily removed.
