Abstract
Description
Technical Field
[0001] The present invention relates to infrastructure construction, and in particular to a roof with hidden projection equipment. Background Art
[0002] Projectors are essential equipment in buildings like conference rooms and banquet halls. For ease of use and to minimize floor space, they are often installed on the roof. As the market evolves, demands for rooftop decoration and aesthetics are becoming increasingly demanding. Consequently, concealing projectors in the roof, with the roof lowered for use, has become the mainstream approach.
[0003] In existing technology, concealed projectors typically feature decorative panels fixed to the bottom of the projector, which move with the projector during raising and lowering. After raising, the panels return to their original position, forming a complete roof decoration. This structure requires spacing between movable decorative panel units, resulting in a poor decorative appearance. This spacing also reduces dust protection for the entire roof. Furthermore, errors in the projector's raising and lowering and resetting often result in incomplete resetting of the movable decorative panel units or their overhanging the decorative surface, resulting in a poor decorative effect. In particular, when all decorative panels are illuminated, the weight and aforementioned resetting issues often prevent the decorative integrity and aesthetics from being achieved.
[0004] Therefore, it is necessary to improve the existing roof-hidden projection equipment to ensure that the movable decorative panel unit (including the movable light panel) can be perfectly and indiscriminately reset after the projection equipment is raised or lowered for use or reset, thereby ensuring the integrity and decorativeness of the roof decorative layer without increasing too much cost.

[0021] Figure 2 is a plan view of the present invention;
[0022] Figure 3 for Figure 1 Enlarged view of point A. DETAILED DESCRIPTION
[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:
[0024] Combine Figure 1-Figure 3 As shown, the roof with hidden projection equipment includes a floor 1 and a decorative layer composed of a light panel, a roof interlayer B is formed between the decorative layer and the floor 1, and a hidden projection equipment is provided in the roof interlayer B;
[0025] The hidden projection equipment includes a projector 3, a projector lifting drive device 4, and a main drive device 5 for driving the projector lifting drive device 4 to move horizontally and bring the projector 3 to a set position. At the set position, the projector lifting drive device 4 drives the projector 3 to move up and down, realizing the use and retraction of the projector;
[0026] The decorative layer is provided with a movable lamp panel 2 at the set position. The movable lamp panel 2 is moved upward by the projector lifting drive device 4 while the main driving device 5 drives the projector 3 lifting drive device to move horizontally. Since the projector lifting drive device 4 is driven to move horizontally, converting the horizontal movement into the up and down movement of the movable lamp panel requires a specific mechanical transmission system, such as a belt transmission device that converts the transmission direction and then uses a small winch device, or a pulley system, etc., which will not be described in detail here.
[0027] In the present invention, the horizontal movement distance of the projector lifting drive device 4 needs to be designed to ensure that the movable lamp panel 2 moves upward a sufficient distance for the projector lifting drive device 4 and the projector 3 to move horizontally to the set position. This can be obtained by calculation based on mechanical transmission, and no further details will be given here. In this structure, when the projector appears, since the movable lamp panel moves upward, it can be directly overlapped with the adjacent lamp panel when resetting, and can be perfectly combined without resetting and calibration, thereby ensuring the integrity of the decoration. At the same time, since it moves upward, it is possible to install decorative strips between other lamp panels in the gap between the movable lamp panel and the adjacent lamp panel, so that after resetting, the overall decoration is more perfect.
[0028] In the present invention, the projector lifting drive device 4 and the main drive device 5 can adopt all devices capable of achieving linear telescopic drive in the prior art, including a nut-screw structure driven by a hollow motor, a hydraulic structure, etc., preferably a drive motor with a long driving distance and a light weight; as shown in the figure, the main drive device 5 is a drive motor that drives the projector lifting drive device 4 to move horizontally through the telescopic mechanism 9, and the projector lifting drive device 4 is also a drive motor that drives the projector to move up and down through the telescopic mechanism 8, which will not be described in detail here;
