Description

Technical Field

[0001] This utility model relates to the field of projection screen technology, and in particular to a ceiling screen shell and ceiling screen. Background Technology

[0002] Projection screens are widely used across various industries, working in conjunction with projectors to deliver various video presentations and playing a significant role in information dissemination. Ceiling screens are a type of projection screen, comprising a housing, a screen within the housing, and a drive roller inside the housing. The screen is rolled up or unfolded by the drive roller. During installation, the housing is mounted on the ceiling, and the screen is stored inside. When projection is needed, the screen is lowered from an opening in the housing. To ensure the aesthetics of the ceiling, a concealed installation method is often used. Mounting holes are made in the ceiling, and baffles are installed around the perimeter of the housing. The main housing is then placed inside the ceiling through the mounting holes, and the baffles conceal the mounting holes. However, in this type of ceiling screen, the baffles around the housing are an integral design with the main body, and the baffles cannot be removed. This prevents selective installation of the baffles according to actual installation conditions, resulting in poor compatibility and versatility of the housing. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to design a ceiling curtain shell and ceiling curtain to improve the compatibility and versatility of ceiling curtain installation.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] Design a ceiling curtain shell, including a hollow main shell, a first baffle detachably disposed on both sides of the main shell in the width direction, and a second baffle detachably disposed on both sides of the main shell in the length direction. The side wall of the main shell in the width direction is inclined downward and has a hanging groove. The hanging groove extends from one end to the other end along the length direction of the main shell. The first baffle is provided with a hook that can be embedded in the hanging groove.

[0006] This design features a ceiling-mounted enclosure that is fixed to the ceiling. Both the first and second baffles are detachable, allowing for selective use of either baffle for either concealed or non-concealed installation depending on the installation conditions. The modular design flexibly adapts to different scenarios. Specifically, when concealment is not feasible and non-concealed installation is the only option, the first and second baffles are unnecessary for aesthetic and simplicity. Since the first baffle is relatively long, conventional screw fixing would require numerous screws, complicating installation and disassembly. Therefore, this design incorporates a riveting structure with mounting grooves and hooks. The mounting grooves on the main enclosure's sidewalls slope downwards, and when the hooks on the first baffle are inserted, a natural gravity-based locking effect prevents detachment due to external forces or vibrations. Furthermore, the mounting grooves extend through both ends of the main enclosure's length, allowing for flexible design of the hook positions and numbers based on the length and weight of the first baffle, enabling hooks to be fixed in any position. When the ceiling allows for concealment, mounting holes are drilled in the ceiling, and the main housing is installed within the ceiling. If wall-mounted installation is not required, the first and second baffles around the main housing are retained to cover the mounting holes. If wall-mounted installation is required, the first and / or second baffles on the wall-mounted side are removed. This modular design allows for flexible adaptation to different scenarios, improving the compatibility and versatility of ceiling curtain installation.

[0007] Furthermore, the first baffle includes a vertical baffle and a horizontal baffle, and the hook is disposed on the side of the vertical baffle near the main housing, with one end of the hook extending to the other end along the length direction of the vertical baffle.

[0008] The first baffle adopts a one-piece molded structure, with the hook running through the entire length of the vertical baffle, so that the suspension force is evenly distributed and the self-locking stability of the hook is improved. Compared with the use of multiple individual small hooks, it can avoid local stress concentration and avoid the problem of hook deformation after long-term use.

[0009] Furthermore, the bottom of the horizontal baffle is flush with the bottom of the main housing.

[0010] The bottom of the horizontal baffle is flush with the bottom of the main housing, enhancing the overall integrity of the product, suitable for modern minimalist style, and hiding the clutter of the mechanical structure.

[0011] Furthermore, the top of the horizontal baffle is provided with an upwardly protruding ridge.

[0012] The raised ribs act as reinforcing ribs, enhancing the longitudinal bending resistance of the horizontal baffle. During installation, only the raised ribs abut against the ceiling, reducing the contact area between the horizontal baffle and the ceiling, preventing ceiling damage caused by installation friction, and also reducing friction noise.

[0013] Furthermore, the second baffle includes a horizontal base plate and a magnetic module disposed on the base plate. The magnetic module can be attracted to the side wall along the length direction of the main housing to connect the base plate to the main housing.

[0014] The second baffle is smaller in size and uses a magnetic module for easy attachment, eliminating the need for screws or clips. This allows for quick installation and removal of the baffle, significantly reducing deployment time. The magnetic module forms a surface contact with the side wall of the main housing, making it more resistant to high-frequency vibrations and preventing it from loosening or falling off, such as when the electric curtain motor is running.

[0015] Furthermore, the magnetic module includes a bracket mounted on the base plate and a magnet mounted at the end of the bracket.

[0016] The bracket is fixed to the base plate by riveting, welding or screwing. The bracket includes at least two fixed ends for fixing magnets. The magnets are connected to the ends of the bracket separately, such as by buckles or threads. When a single magnet is damaged, it can be replaced independently, reducing maintenance costs.

[0017] Furthermore, the sidewall of the main housing along its length is provided with a positioning structure, and the end of the bottom plate near the main housing is embedded in the positioning structure.

[0018] The end plate of the main housing is misaligned with the bottom of the main housing to form a positioning structure. The magnetic module of the second baffle is attached to the end plate of the main housing. The positioning structure positions the bottom plate to ensure that the bottom plate is in a horizontal state.

[0019] Furthermore, the bottom of the base plate is flush with the bottom of the main housing.

[0020] The bottom of the base plate is flush with the bottom of the main shell, enhancing the overall integrity of the product, suitable for modern minimalist style, and hiding the clutter of the mechanical structure.

[0021] Furthermore, a fixing assembly is provided on the top of the main housing, the fixing assembly including a fixing plate slidably disposed on the main housing and a fixing base for locking the fixing plate.

[0022] The fixing base is shaped like a "Z", and the two wings can be fixed to the ceiling using expansion bolts or other fasteners. The fixing plate is then connected to the fixing base with bolts, thus achieving the fixed installation of the ceiling curtain shell. In addition, a guide rail is set on the top of the main shell, and the fixing plate is locked in the guide rail and can slide continuously within the guide rail, thereby adapting to different fixing base spacings and solving the compatibility problem of traditional pre-embedded fixing holes.

[0023] A ceiling screen is also designed, including the aforementioned ceiling screen shell.

[0024] The ceiling screen in this solution includes the aforementioned ceiling screen housing, a screen located inside the housing, and a drive roller located inside the housing. The screen is rolled up or unfolded by the drive roller. By using the aforementioned ceiling screen housing, the ceiling screen can be installed in a concealed or non-concealed manner, flexibly adapting to different scenarios and improving the compatibility and versatility of ceiling screen installation.

[0031] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Example 1:

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a ceiling curtain shell, including a hollow main shell 1, a first baffle 2 detachably disposed on both sides of the main shell 1 in the width direction, and a second baffle 3 detachably disposed on both sides of the main shell 1 in the length direction.

[0033] like Figure 1 and Figure 2 As shown, the sidewall of the main housing 1, inclined downwards in the width direction, has a hanging groove 11. The hanging groove 11 extends from one end to the other along the length direction of the main housing 1. The first baffle 2 includes a vertical baffle 21 and a horizontal baffle 22. The vertical baffle 21 has a hook 23 that can be embedded in the hanging groove 11. The hook 23 is located on the side of the vertical baffle 21 near the main housing 1 and extends from one end to the other along the length direction of the vertical baffle 21. The first baffle 2 adopts an integral molding structure, and the hook 23 runs through the entire length of the vertical baffle 21, so that the suspension force is evenly distributed and the self-locking firmness of the hook is improved. Compared with the form of multiple small individual hooks, it can avoid local stress concentration and avoid the problem of deformation of the hook 23 after long-term use. Of course, in other embodiments, when the first baffle is lighter, the hook can also be a segmented long hook, as long as the strength is guaranteed. The top of the horizontal baffle 22 has an upwardly protruding rib 24, which serves as a reinforcing rib to enhance the longitudinal bending resistance of the horizontal baffle. During installation, only the protruding strip 24 abuts against the ceiling, reducing the contact area between the horizontal baffle 22 and the ceiling, avoiding damage to the ceiling due to installation friction, and reducing friction noise. The bottom of the horizontal baffle 22 is flush with the bottom of the main housing 1. This flush design enhances the overall integrity of the product, is suitable for modern minimalist styles, and hides the clutter of the mechanical structure.

[0034] like Figures 1 to 3As shown, the second baffle 3 includes a horizontal base plate 31 and a magnetic module 32 mounted on the base plate 31. The magnetic module 32 can be attracted to the side wall of the main housing 1 along its length to connect the base plate 31 to the main housing 1. The second baffle 3 is small in size and achieves "one-click attachment" through the magnetic module 32, eliminating the need for screws or clips, allowing for quick installation or removal of the baffle and significantly reducing deployment time. The magnetic module 32 forms surface contact with the side wall of the main housing 1, making it more resistant to high-frequency vibrations, such as during the operation of an electric curtain motor, preventing loosening and detachment. The magnetic module 32 includes a bracket 321 mounted on the base plate 31 and a magnet 322 mounted at the end of the bracket 321. The bracket 321 is fixed to the base plate 31 by riveting, welding, or screws. The bracket 321 includes at least two fixed ends for fixing the magnet 322. The magnet 322 and the end of the bracket 321 are connected separately, such as by clips or threads, allowing for independent replacement of a single damaged magnet 322, reducing maintenance costs. The end plate of the main housing 1 is offset from the bottom of the main housing 1 to form a positioning structure 12. The magnetic module 32 of the second baffle 3 is attached to the end plate of the main housing 1. The positioning structure 12 positions the bottom plate 31 to ensure that the bottom plate 31 is in a horizontal state. The bottom of the bottom plate 31 is flush with the bottom of the main housing 1. This flush design enhances the overall integrity of the product, is suitable for modern minimalist style, and hides the clutter of the mechanical structure.

[0035] like Figure 1 and Figure 2 As shown, a set of fixing components 4 are respectively provided at both ends of the top of the main housing 1. The fixing components 4 include a fixing plate 41 slidably disposed on the main housing 1 and a fixing base 42 for locking the fixing plate 41. The fixing base 42 is Z-shaped, and the two wings can be fixed in the ceiling by expansion bolts or other fasteners. Then, the fixing plate 41 is connected to the fixing base 42 by bolts, so as to realize the fixed installation of the ceiling curtain shell. In addition, a guide rail is provided at the top of the main housing 1. The fixing plate 41 is locked in the guide rail and can slide continuously in the guide rail, so as to adapt to different spacings of fixing bases 42 and solve the compatibility problem of traditional pre-embedded fixing holes.

[0036] In this embodiment, the ceiling curtain shell is fixed to the ceiling. Both the first baffle 2 and the second baffle 3 are detachable. Depending on the actual installation conditions, either the first baffle 2 or the second baffle 3 can be used for concealed or non-concealed installation. Through modular design, it can flexibly adapt to different scenarios. Specifically, when the ceiling does not have the conditions for concealment and only non-concealed installation is possible, the first baffle 2 and the second baffle 3 are not needed for the sake of aesthetics and simplicity. Since the first baffle 2 is relatively long, if a conventional screw fixing method is used, a large number of screws will be used, making installation or disassembly more complicated. Therefore, in this embodiment, the hanging groove 11 and the hook 23 cooperate with a riveting structure. The hanging groove 11 on the side wall of the main shell 1 is inclined downward. After the hook 23 of the first baffle 2 is inserted, a natural gravity locking effect is formed to prevent it from falling off due to external shaking or vibration. In addition, the hanging groove 11 runs through both ends of the main shell 1 in the length direction. According to the length and weight of the first baffle 2, the position and number of hooks 23 can be flexibly designed, allowing the hooks 23 to be fixed in any position. When the ceiling allows for concealment, mounting holes are made in the ceiling, and the main housing 1 is installed inside the ceiling. If wall-mounted installation is not required, the first baffle 2 and the second baffle 3 around the main housing 1 are retained to cover the mounting holes. If wall-mounted installation is required, the first baffle 2 and / or the second baffle 3 on the wall-mounted side are removed. Through this modular design, different scenarios can be flexibly adapted, improving the compatibility and versatility of ceiling curtain installation. Example 2:

[0037] This embodiment provides a ceiling screen, including the aforementioned ceiling screen housing, a screen located inside the housing, and a drive roller located inside the housing. The screen is rolled up or unfolded by the drive roller. By using the aforementioned ceiling screen housing, the ceiling screen can be installed in a concealed or non-concealed manner, flexibly adapting to different scenarios and improving the compatibility and versatility of ceiling screen installation.
