Description

Technical Field

[0001] This application relates to the field of elevator technology, and in particular to an elevator ceiling. Background Technology

[0002] With the continuous development of elevator technology, the interior design of elevator cars is increasingly focusing on functionality and aesthetics. The ceiling structure, as a crucial component of the elevator car, not only provides lighting but also significantly impacts the overall visual appeal. However, currently common elevator ceiling structures suffer from the following problems in practical use: Traditional elevator ceiling light tubes or panels typically use fixed connections, often requiring complete removal for later maintenance, leading to cumbersome disassembly and reassembly processes and higher maintenance costs. This is especially problematic when car space is limited, as traditional mechanical fixing methods, which are difficult to disassemble or require multiple people, further complicate the process. Furthermore, current technology often fails to consider sealing when installing light tubes or panels, allowing dust and insects to easily enter, affecting aesthetics, lighting performance, and potentially shortening the lifespan of the lights. Finally, in traditional ceiling designs, fixing components such as bolts and clamps are usually exposed, impacting the overall aesthetics and failing to meet the aesthetic requirements of modern elevator design. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an elevator ceiling that effectively prevents dust and insects from entering the lighting area, while also enabling quick assembly and disassembly, improving the convenience of later maintenance and reducing maintenance costs.

[0005] The elevator ceiling according to the embodiments of this application has at least the following beneficial effects: The elevator ceiling of the embodiment provides mounting recesses on the ceiling substrate and places the light panel assembly (including lighting units and a cover plate) within these recesses, allowing the cover plate to cover the opening of the mounting recess, thus forming a closed space together with the mounting recess. Since the lighting unit is relatively isolated from the outside world, it effectively prevents dust and impurities from entering the lighting area, reducing cleaning frequency and dust accumulation, and extending the service life of internal electronic components. The cover plate and the ceiling substrate are assembled using fixing components, which can be quickly disassembled as needed, facilitating the direct removal of the cover plate for inspection or replacement of the lighting unit without completely disassembling the ceiling, significantly improving the convenience of later maintenance and reducing maintenance costs. The embedded mounting recess and cover plate design makes the light panel assembly more stable while maintaining a smooth and integrated overall structure, contributing to a good aesthetic appearance inside the elevator car. The elevator ceiling of the embodiment avoids safety hazards and aesthetic degradation caused by insects and dust entering the lighting system. Simultaneously, the quick disassembly and assembly of the lamp cover through the fixing components improves the efficiency of later inspection and maintenance.

[0028] like Figure 1 and Figure 3As shown, the elevator ceiling in this embodiment mainly includes a ceiling base plate 100, a light panel assembly 200, and a fixing assembly. The ceiling base plate 100 has a mounting recess for embedding the light panel assembly 200. The light panel assembly 200 includes a lighting unit and a cover plate 210, wherein the lighting unit (not shown) is placed within the mounting recess, and the cover plate 210 covers the opening of the mounting recess. The fixing assembly is disposed on the ceiling base plate 100 to fix the cover plate 210 to the ceiling base plate 100, so that the cover plate 210 and the mounting recess together form a closed space, thereby achieving sealed protection of the lighting unit and quick assembly / disassembly. Optionally, the ceiling base plate 100 can be a flat structure of metal or composite material, pre-stamped or provided with a sized mounting recess. The inner circumferential dimensions of the mounting recess match the outer circumferential dimensions of the cover plate 210, so that the cover plate 210 can be embedded in the mounting recess during subsequent assembly. The depth of the mounting recess is designed according to the thickness of the lighting unit, allowing the lighting unit to be accommodated within it and to remain flush with or slightly below the surface of the ceiling substrate 100. In the light panel assembly 200, the lighting unit can be a high-power LED light panel or other suitable lighting modules, and is fixed to the bottom or periphery of the mounting recess by bolts, snap-fits, adhesives, etc. The cover plate 210 is generally made of a material with good light transmittance (such as acrylic sheet, impact-resistant PC sheet, etc.), and its thickness can be appropriately increased to balance impact resistance and durability. After the cover plate 210 is installed in place, it fits snugly against the opening of the mounting recess and is essentially seamlessly connected, thus forming a closed protection for the lighting unit. The fixing components can employ several structural parts for holding or limiting (such as holding parts 310, screws, clips, or elastic pins, etc.) to ensure the stability of the cover plate 210 on the ceiling substrate 100. Preferably, in order to facilitate subsequent maintenance or replacement of lighting units, the fixing components can be designed as detachable structures, such as screws or clips distributed in the edge area of ​​the ceiling base plate 100. Operators only need to remove the fixing components inside the elevator car to remove the cover plate 210 without having to completely remove the ceiling base plate 100, thereby greatly improving the efficiency of later maintenance and reducing maintenance costs.

[0029] Through the above structural layout, the elevator ceiling in this embodiment not only reduces the possibility of dust entering the lighting area and causing damage or contamination to the LED light panels, but also allows for easy removal of the cover plate 210 of the light panel assembly 200 before operating the lighting unit when maintenance or replacement of the lighting unit is required, without having to remove the entire elevator ceiling panel. The overall process is simple, the structure is stable, and the aesthetics are high, meeting the comprehensive needs of the elevator interior for lighting, protection, and easy maintenance.

[0030] Understandably, in order to prevent the cover plate 210 from falling directly into the bottom of the mounting recess and encroaching on the installation space of the lighting unit, it is necessary to set up a corresponding support structure in the mounting recess to form a sufficient enclosed space.

[0031] Therefore, in some implementations, the mounting recess in the elevator ceiling is divided into a first receiving portion and a second receiving portion located inside the first receiving portion. The second receiving portion is used to place the lighting unit (such as an LED light panel), and its bottom or sidewalls can be fixed to the lighting unit by means of screws, clips, or rivets, so that it is securely placed in the deep area of ​​the recess; the first receiving portion surrounds the outer ring of the second receiving portion, and a cover plate is placed there, so that the cover plate abuts against the bottom surface of the first receiving portion, and after the cover plate is attached to the sidewalls of the first receiving portion around its perimeter, a relatively independent installation space is formed between the cover plate and the lighting unit. Through the above structural design, the cover plate will not press directly on the bottom of the mounting recess, thus avoiding occupying the necessary installation and heat dissipation space for the lighting unit; the cover plate covering the opening of the first receiving part can remain flush with the ceiling substrate, which not only improves the continuity of appearance, but also effectively protects the inside of the lamp panel from dust and foreign objects; when it is necessary to repair or replace the lighting unit, it is only necessary to loosen the fixing components for the cover plate and the first receiving part, so that the cover plate can be lifted and directly contacted the deep second receiving part, making maintenance more convenient.

[0032] Similarly, such as Figure 5 and Figure 7 As shown, in some embodiments, three or more support members 110 may be provided on the bottom or sidewall of the mounting recess to provide reliable support for the cover plate 210. This ensures that after the cover plate 210 is combined with the ceiling substrate 100, it will not directly touch the bottom of the recess, thus guaranteeing the installation and heat dissipation space required for the lighting unit. By evenly distributing the support members 110 at multiple locations on the bottom or sidewall of the mounting recess, the cover plate 210 can be stably supported on these support members 110. After the cover plate 210 is installed in place, a certain height or gap is formed between it and the support members 110, reserving sufficient space to accommodate the lighting unit and related accessories. When it is necessary to inspect or replace the lighting unit, simply remove the fixing components of the cover plate 210 to lift or remove the cover plate 210, and then operate the internal lighting unit. Unlike the multi-level accommodating structure (with a first accommodating slot and a second accommodating slot) mentioned above, the support members 110, which are discretely distributed at the bottom or sidewalls of the recess, are used to support and limit the cover plate 210. The advantages are as follows: simple manufacturing and processing, flexible support position, and the appropriate number and layout of support members 110 can be configured according to the model and size of the lighting unit; it is easier to meet the material and thickness requirements of different cover plates 210, ensuring a balance between support strength and installation convenience; when it is necessary to upgrade or improve the lighting scheme, there is no need to make significant changes to the recess structure, only the number and height of the support members 110 need to be adjusted accordingly to adapt to the new lighting unit arrangement.

[0033] Both of the above embodiments can effectively prevent the cover plate 210 from falling directly into the bottom of the installation recess, avoiding encroachment on the lighting unit space, while improving the ease of disassembly and assembly and internal sealing, and adapting to various elevator ceiling installation and maintenance needs.

[0034] Understandably, in addition to providing a first receiving portion or support member 110 inside the mounting recess, the elevator ceiling in this embodiment is also equipped with a fixing assembly 300 and a covering decorative strip 330 for stably mounting the cover plate 210 onto the ceiling base plate 100. Figure 4 Figure 5 and Figure 6 As shown, in some embodiments, the fixing component 300 includes several holding members 310 and several fixing screws 320, used to press and position the cover plate 210 on the corresponding supporting structure. Once the fixing component 300 is fixed in place, the cover plate 210, together with the mounting recess, forms a closed lighting space, preventing external dust or foreign objects from entering and ensuring the safety and stability of the lighting unit during use. In terms of operation, the cover plate 210 can first be placed on the first receiving part or the support member 110, so that the cover plate 210 is supported by the supporting structure and approximately flush with the ceiling substrate 100. Then, according to the fixing holes (or slot positions) pre-drilled around the edge or recess of the cover plate 210, the operator sequentially installs the holding members 310 and the fixing screws 320 onto the ceiling substrate 100, so that the holding members 310 abut against or clamp the edge of the cover plate 210, ultimately achieving the pressing and fixing of the cover plate 210. For cover plates 210 of different materials and shapes, different lengths, quantities or shapes of clamping parts 310 can be selected as needed to ensure uniform force distribution, stable installation and convenient assembly and disassembly.

[0035] Furthermore, such as Figure 3 As shown, to avoid the screws and retaining members 310 of the fixing component 300 being exposed within the field of vision and affecting the aesthetics of the car, the elevator ceiling in this embodiment can also add several decorative strips 330 to the fixing component 300. The decorative strips 330 can be made of metal or plastic and are installed on the surface of the ceiling base plate 100 by countersunk screws, hooks, or adhesive methods, covering the area of ​​the retaining member 310 and the fixing screw 320. This not only hides the retaining member 310 and the screw heads, but also allows for diverse designs of the decorative strips 330 to match the elevator interior style, thereby maintaining visual unity with the overall ceiling and enhancing the aesthetics of the car.

[0036] In some embodiments, such as Figure 1 and Figure 2As shown, in this embodiment, two ventilation components 400 are respectively provided on opposite sides of the ceiling base plate 100. The ventilation components 400 and the ceiling base plate 100 can be detachably connected by bolts to form a functional area for ventilation and heat dissipation. To ensure the flatness of the overall appearance, the main body of the ventilation component 400 is approximately on the same horizontal plane as the ceiling base plate 100. The ventilation component 400 is connected to the ceiling base plate 100 and maintains structural strength through a bend formed by pre-reserving or bending the side edge of the ceiling base plate 100. For example, the ventilation component 400 includes a ventilation base groove (not shown in the figure), a fan 410, and a ventilation cover plate 420. During manufacturing and assembly, a bent section is first formed on the side of the ceiling base plate 100 by stamping or bending, so that the height of the bent section is adapted to the installation requirements of the ventilation base groove. The corresponding mounting edge of the ventilation base groove fits into the bent section, and a detachable connection is achieved by several bolts or clips. The ventilation cover plate 420 cooperates with the ventilation base groove to cover the radial opening of the ventilation base groove. Several ventilation holes are evenly distributed on the ventilation cover plate 420 to ensure air circulation between the inside and outside of the elevator car. The fan 410 can be installed in the ventilation base groove and communicates with the cavity inside the ventilation base groove through its built-in air duct. Combined with the ventilation holes on the ventilation cover plate 420, it realizes the extraction or circulation of air inside the car.

[0037] In some implementations, such as Figure 1 and Figure 2 As shown, the elevator ceiling in this embodiment also includes a side plate 500. The side plate 500 is detachably connected to the two opposite sides of the ceiling plate 100 by bolts, or detachably connected to the two ventilation grooves on opposite sides by bolts. The side plate 500 can be connected to the ceiling plate 100 or the ventilation grooves using a connection method similar to that of the ventilation assembly 400 described above. The side plate 500 forms an extension section adjacent to the central functional area of ​​the ceiling. This extension section can be designed with different lengths or widths according to the internal space requirements of the elevator, so that the entire elevator ceiling can accommodate elevator cars of different sizes. At the same time, the side plate 500 can accommodate or install various non-critical functional components (for example, a secondary lighting unit 510 or other types of sensors can be installed on the side plate 500).

[0038] Understandable, such as Figure 2 As shown, the ceiling substrate 100 and side substrate 500 in the above embodiments typically contain large plates. These large-area plates often have lower structural strength and are prone to deformation or shaking during actual use. Therefore, in some embodiments, a support frame 600 can be provided on the back of the ceiling substrate 100 and side substrate 500 to enhance the structural rigidity of the ceiling substrate 100 and side substrate 500.

[0039] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
