Description

Technical Field

[0001] The utility model relates to the technical field of projection equipment, in particular to a structure capable of concealing a projection equipment. Background Art

[0002] As we all know, projectors are widely used in conference rooms, exhibition halls, and homes. As a replacement for televisions, they offer advantages such as compact size and the ability to zoom in and out. With the passage of time, projectors are becoming increasingly popular and are now used in ordinary households. Currently, with the advancement of global urbanization, urban environments are becoming increasingly crowded, and with global energy shortages, urban congestion will only intensify. In this context, reducing the space occupied by indoor electrical appliances and increasing their multifunctionality are also important goals and directions to consider in exhibition space design.

[0003] Chinese patent publication number CN208267209U discloses a suspended ceiling capable of concealing a projection device. The ceiling comprises a keel frame, a suspension rod, and a decorative panel, wherein the decorative panel is provided with an installation opening to prevent the projection device from being raised or lowered. The suspended ceiling further comprises a downwardly opening concealed cavity formed upward from the side of the installation opening, a pull rod capable of vertically moving up and down, a drive mechanism disposed on the keel frame for driving the pull rod, and a seal and decorative member disposed at the bottom of a positioning frame of the projection device for closing the opening of the concealed cavity. The pull rod is movably disposed in the concealed cavity and its lower end is fixedly connected to the positioning frame of the projection device. This utility model fully utilizes the interior space of the suspended ceiling to conceal the projection device in a suspended manner. At the same time, decorative members can be installed at the bottom of the projection device, thereby completely changing the monotony of the ceiling panel and greatly enhancing the aesthetics of the suspended ceiling.

[0004] However, the above technical solution has the following shortcomings: the projector and the driving mechanism are hidden in the ceiling. On the one hand, the tilt angle of the projector cannot be adjusted during use, which affects the imaging effect of the projector. On the other hand, if the driving mechanism that cooperates with the retraction and extension of the projector fails, the projector will be directly exposed to the outside and cannot be put into the hidden position or cannot be taken out of the hidden position for use.
