Description

Technical Field

[0001] This utility model relates to the field of holographic projection technology, and in particular to an assembled holographic projection device. Background Technology

[0002] A projector, also known as a projector, is a device that projects images or videos onto a screen. It can be connected to computers, VCD players, DVD players, Blu-ray players, game consoles, DV cameras, etc., through various interfaces to play corresponding video signals. The image projected onto the screen by a typical projector is usually flat. To achieve a better display effect, holographic projection is also available, which projects a flat image into a 3D stereoscopic visual effect.

[0003] Common holographic projection devices typically consist of a projector paired with a 45° angled glass or holographic film to project a holographic image. The position of the holographic film or other imaging device is usually fixed. If the user's height is just right to see the holographic film at eye level, the holographic image effect is the best; otherwise, it will affect the viewing effect. Fixed holographic films cannot meet the above requirements. Therefore, this application proposes an assembled holographic projection device to solve the above problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides an assembled holographic projection device, including a base and a canopy. The canopy is installed on the top of the base. The base includes a base frame, and the canopy includes a canopy frame. The canopy frame is fixedly connected to the top of the base frame. A first profile is fixedly connected to the top of each of the two inner sides of the base frame. A rectangular frame is movably connected between the two first profiles through a pivot. A holographic film is fixedly connected inside the rectangular frame. An L-shaped bracket is fixedly connected to the top of the rear side of the rectangular frame. A projector is movably connected to the bottom of the L-shaped bracket through a damping pivot. A second profile is fixedly connected to each of the two sides of the rectangular frame. An electric push rod is movably connected between the first profile and the second profile through a movable hinge.

[0006] Preferably, the rectangular frame is located inside the ceiling, and the holographic film has an inclination angle of °.

[0007] Preferably, the canopy further includes multiple canopy light-shielding panels, which are respectively fixedly connected to both sides and the top of the canopy frame.

[0008] Preferably, the base further includes multiple base light-shielding plates, which are respectively fixedly connected to the front and rear sides and the left and right sides of the base frame.

[0009] Preferably, the base frame has multiple support legs fixedly connected to its bottom.

[0010] Compared with related technologies, the assembled holographic projection device provided by this utility model has the following beneficial effects:

[0011] The angles of the rectangular frame and the holographic film can be quickly adjusted using an electric push rod, allowing the holographic film to be viewed at the optimal angle. When the angle of the holographic film is adjusted, the projector will move synchronously with the rectangular frame via an L-shaped bracket, ensuring that the image projected onto the holographic film is not affected and remains at the optimal angle. Through these methods, users can enjoy the best holographic viewing effect at different heights, making it very convenient to use. Attached Figure Description

[0018] Implementation examples, by Figure 1-5The present invention includes a base 1 and a canopy 2. The canopy 2 is installed on top of the base 1. The base 1 includes a base frame 11, and the canopy 2 includes a canopy frame 21. The canopy frame 21 is fixedly connected to the top of the base frame 11. A first profile 7 is fixedly connected to the top of each of the two inner sides of the base frame 11. A rectangular frame 3 is movably connected between the two first profiles 7 through a pivot. A holographic film 4 is fixedly connected inside the rectangular frame 3. An L-shaped bracket 5 is fixedly connected to the top of the rear side of the rectangular frame 3. A projector 6 is movably connected to the bottom of the L-shaped bracket 5 through a damping pivot. A second profile 8 is fixedly connected to each of the two sides of the rectangular frame 3. An electric push rod 9 is movably connected between the first profile 7 and the second profile 8 through a movable hinge.

[0019] The base frame 11, the roof frame 21, and the rectangular frame 3 are all assembled from profiles of the same type as the first profile 7 and the second profile 8.

[0020] The rectangular frame 3 is located inside the ceiling 2, and the holographic film 4 has an inclination angle of 45°. The holographic film 4 at a 45° angle, together with the projector 6, has a better holographic imaging effect.

[0021] The canopy 2 also includes multiple canopy light-shielding plates 22, which are fixedly connected to the sides and top of the canopy frame 21 respectively. The base 1 also includes multiple base light-shielding plates 12, which are fixedly connected to the front and rear sides and the left and right sides of the base frame 11 respectively. The canopy light-shielding plates 22 and the base light-shielding plates 12 can reduce the influence of external light sources on the holographic imaging of the holographic film 4.

[0022] The bottom of the base frame 11 is fixedly connected to multiple support legs 13, which can support the entire device.

[0023] Working principle:

[0024] When performing holographic projection, the projector 6 can be turned on to project the image onto the holographic film 4. The image will then be displayed as a holographic image through the holographic film 4. When the angle of the holographic film 4 needs to be adjusted according to usage requirements, the electric push rod 9 can be used to push the holographic film 4 to rotate, thereby changing the tilt angle of the holographic film 4. Since the projector 6 is directly installed behind the holographic film 4 through the L-shaped bracket 5 and the rectangular frame 3, the image projected by the projector 6 onto the holographic film 4 will not be affected no matter how the tilt angle of the holographic film 4 is changed. After the angle of the holographic film 4 is changed, the holographic image generated by the holographic film 4 can be viewed from different heights at the optimal angle.
