Description

Car ceiling assembly structure and elevator car Technical Field

[0001] This utility model relates to the field of elevator cars, and in particular to a car top ceiling assembly structure and an elevator car. Background Technology

[0002] In existing technologies, traditional elevator car tops and ceilings are typically designed as separate units. The car top structure is often a flat panel or a simple bent frame, requiring an additional ceiling decorative layer, resulting in a complex overall structure, heavy weight, and cumbersome installation procedures. Currently, the ceiling decorative panels are mostly fixed to the car top using bolts or clips, leading to exposed seams and a lack of visual appeal. Furthermore, LED strips are usually directly embedded in the ceiling edge, causing glare from direct light and affecting visual quality. In addition, traditional car top reinforcements are often welded or spliced, resulting in uneven structural strength and significant weight, which is detrimental to elevator energy efficiency. Therefore, there is an urgent need for an integrated, lightweight, and aesthetically pleasing combined car top and ceiling structure.

[0003] In addition, in existing ceiling structures, light strips are usually installed in enclosed light box structures, such as the light box structure for elevator ceilings disclosed in the utility model patent with authorization announcement number CN222256361U. Although it is convenient to protect the light strip and avoid direct light from affecting visual comfort, on the one hand, the light box structure will occupy a large volume, and on the other hand, the maintenance of the light strip is also more complicated. Summary of the Invention

[0004] Therefore, in order to solve the above problems, this utility model provides a car ceiling combination structure and an elevator car.

[0005] This utility model is achieved through the following technical solution:

[0006] A car roof ceiling assembly structure includes a rectangular top plate. At least three outer edges of the top plate are bent to form bent components integrally formed with the top plate. Four supporting reinforcing ribs are provided on the inner periphery of the top plate, each rib being parallel to one side of the top plate. A rectangular mounting groove is formed on the inner periphery of the four supporting reinforcing ribs. A ceiling decorative panel is installed in the mounting groove. The outer periphery of the ceiling decorative panel is spaced apart from the supporting reinforcing ribs, and a light strip is provided at the interval between the ceiling decorative panel and the supporting reinforcing ribs. A cover plate is also connected to the bottom of the top plate. The cover plate is generally square-shaped, and a rectangular central clearance hole is formed in the center of the cover plate. The cover plate is fixed to the bent components and the supporting reinforcing ribs, and the inner periphery of the cover plate extends inward to directly below the light strip. The central clearance hole is located directly below the ceiling decorative panel.

[0007] Preferably, each of the bending components includes a first bending portion that is bent vertically from the outer peripheral edge of the top plate and a second bending portion that is bent vertically from the top of the first bending portion toward the inner peripheral direction of the top plate. The first bending portion is parallel to and spaced apart from a supporting reinforcing rib on the same side, and the second bending portion is located directly below the gap between the first bending portion and the supporting reinforcing rib.

[0008] Preferably, the two vertical sides of the top plate are bent to form a first bending member, and one of the horizontal sides of the top plate is bent to form a second bending member. A front reinforcing rib is fixed to the inner side of the other horizontal side of the top plate, and the front reinforcing rib is parallel to the supporting reinforcing rib provided on the same side.

[0009] Preferably, the top of each end of the front reinforcing rib has an outwardly extending connecting portion, and each connecting portion is connected to one of the first bending members.

[0010] Preferably, the two ends of the second bend of the second bending member are respectively formed with beveled edges, and the first bending member has corresponding beveled edges formed at the connection between its second bend and the second bending member.

[0011] Preferably, the cover plate includes at least a first connecting portion and a second connecting portion from the inside out. The first connecting portion is connected to the second bending portion of each bending edge and the front reinforcing rib, respectively, and the second connecting portion is connected to the four supporting reinforcing ribs, respectively.

[0012] Preferably, a third connecting portion is also formed on the inner periphery of the second connecting portion, the third connecting portion extending directly below the light strip and covering the bottom of the light strip.

[0013] Preferably, the first connecting part, the second connecting part, and the third connecting part are integrally formed. The first connecting part is respectively riveted to the second bending part of each bending edge and the front reinforcing rib by screws, and the second connecting part is respectively riveted to the four supporting reinforcing ribs by screws.

[0014] Preferably, each of the supporting reinforcing ribs is a C-shaped bent tube, and the opening side of each supporting reinforcing rib faces outward.

[0015] The elevator car includes the aforementioned ceiling assembly structure.

[0016] The beneficial effects of this utility model's technical solution are mainly reflected in:

[0017] 1. Through the sheet metal structure design of integral bending and forming of the outer circumference of the top plate and C-shaped reinforcing ribs, the rigidity of the car roof is ensured while reducing redundant parts, thereby reducing the overall weight. No additional welding or assembly of the frame is required. The C-shaped reinforcing ribs have both support and wiring functions. Their bending structure provides anti-deformation capacity in the vertical direction and forms a cable channel in the horizontal direction, avoiding the occupation of the car roof height by traditional exposed wiring. The ceiling decorative panel is embedded in the mounting groove surrounded by the reinforcing ribs. With the cover design of the edge cover plate, a seamless splicing decorative surface display is achieved, realizing the integrated combination structure of the car roof and the ceiling.

[0018] 2. The cover plate serves two purposes: firstly, it conceals and protects the bent and reinforced structure at the edge of the car top; secondly, the inner circumference of the cover plate extends inward to form a light-shielding structure for the LED strip, allowing light to diffuse evenly after secondary reflection, avoiding direct glare and improving the comfort of the car's lighting environment. Furthermore, the LED strip and wiring can be hidden within the gap between the reinforcing ribs and the decorative panel, allowing for easy replacement or maintenance by removing only a portion of the cover plate, facilitating installation and repair, significantly reducing maintenance costs, and saving overall space and weight on the car top. In addition, the LED strip can utilize RGB LEDs that can change to various colors, thus increasing the richness of the elevator car top decoration design. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" in this solution are used for descriptive purposes only and should not be construed as indicating or implying a ranking of importance, or implicitly specifying the number of technical features shown. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0029] This utility model discloses a car roof ceiling assembly structure, as shown in Figures 1-5, including a rectangular top plate 1. At least three of the outer peripheral edges of the top plate 1 are bent to form a bent component integrally formed with the top plate 1. In a preferred embodiment, only three of the top plate 1 are bent to facilitate the subsequent installation of various components inside the top plate 1.

[0030] As shown in Figures 3 and 5, four supporting reinforcing ribs 2 are provided on the inner periphery of the top plate 1, and each supporting reinforcing rib 2 is arranged parallel to one of the edges of the top plate 1, forming a rectangular mounting groove 3 on the inner periphery of the four supporting reinforcing ribs 2. A ceiling decorative panel 4 is installed in the mounting groove 3. The ceiling decorative panel 4 can be made of PC board or other materials. The fixing method between the ceiling decorative panel 4 and the top plate 1 can also refer to existing technologies, such as glue fixing, screw riveting, welding, etc., which will not be elaborated here. The outer periphery of the ceiling decorative panel 4 is spaced apart from the supporting reinforcing ribs 2, and a light strip 7 is provided at the interval between the ceiling decorative panel 4 and the supporting reinforcing ribs 2. The light strip 7 can be an RGB LED light strip. Since the LED in the RGB LED light strip contains three independent light-emitting units of red, green and blue, various light-changing modes can be achieved by adjusting the brightness and mixing ratio of the three colors. The light-changing form of the RGB LED light strip can be adjusted according to actual needs, and the structure and light-changing method of the RGB LED light strip can refer to existing technologies, which will not be elaborated here.

[0031] The shape and pattern of the ceiling decorative panel 4 can be customized. In one embodiment, as shown in Figure 3, the ceiling decorative panel 4 can be a rectangular decorative panel. In other embodiments, as shown in Figure 4, the ceiling decorative panel 4 can also be other shapes, and light strips 7 are arranged along the outer periphery of the ceiling decorative panel 4.

[0032] As shown in Figures 1 and 2, a cover plate 5 is also connected to the bottom of the top plate 1. The cover plate 5 is generally square in shape, and a rectangular central clearance hole is formed in the middle of the cover plate 5. The cover plate 5 is fixed to the bending member and the supporting reinforcing rib 2 respectively, and the inner circumference of the cover plate 5 extends inward to directly below the light strip 7. The central clearance hole is located directly below the ceiling decorative panel 4, thereby exposing the decorative surface of the ceiling decorative panel 4. The cover plate 5 is used to wrap the bending member and supporting reinforcing rib 2 and other reinforcing structures on the inner circumference of the top plate 1, and can also be used to shield the area directly below the light strip 7, thereby avoiding direct light illumination and reducing visual comfort. At the same time, the wiring of the light strip 7 can be shielded by the cover plate 5, further improving the aesthetics and safety performance of the overall structure of the car roof.

[0033] As shown in Figures 5-7, in some embodiments, each of the bending components includes a first bending portion 103 that is vertically bent from the outer peripheral edge of the top plate 1 and a second bending portion 104 that is vertically bent from the top of the first bending portion 103 toward the inner peripheral direction of the top plate 1. The first bending portion 103 is parallel to and spaced apart from a supporting reinforcing rib 2 on the same side. The second bending portion 104 is located directly below the gap between the first bending portion 103 and the supporting reinforcing rib 2, thereby preventing the second bending portion 104 from obstructing the supporting reinforcing rib 2 and facilitating the subsequent fixing of the cover plate 5 to the supporting reinforcing rib 2. In addition, the gap between the first bending portion 103 and the supporting reinforcing rib 2 can be used to arrange the wiring of the light strip 7 or other electrical components, and the second bending portion 104 can be used to shield the wiring to ensure safety.

[0034] As shown in Figures 1, 2, 5, and 6, in some embodiments, the two vertical sides of the top plate 1 are bent to form a first bent member 101, and one of the horizontal sides of the top plate 1 is bent to form a second bent member 102. A front reinforcing rib 6 is fixed to the inner side of the other horizontal side of the top plate 1. The front reinforcing rib 6 is parallel to the supporting reinforcing rib 2 provided on the same side. The top of each end of the front reinforcing rib 6 is formed with an outwardly extending connecting portion 601. Each connecting portion 601 is connected to one of the first bent members 101. Specifically, the bottom of the connecting portion 601 can be welded to the second bent portion 104 of the first bent member 101, and the end of the connecting portion 601 can also be welded to the first bent portion 103 of the first bent member 101.

[0035] As shown in Figures 5 and 7, in one embodiment, the two ends of the second bend portion 104 of the second bending member 102 are respectively formed with beveled edges 8. The first bending member 101 forms corresponding beveled edges 8 at the connection between its second bend portion 104 and the second bending member 102. The beveled edges 8 of the first bending member 101 can be welded and fixed to the beveled edges 8 of its corresponding second bending member 102 to improve the stability and sealing performance of the connection between the first bending member 101 and the second bending member 102.

[0036] As shown in Figures 1 and 2, in one embodiment, the cover plate 5 includes at least a first connecting portion 501 and a second connecting portion 502 from the inside out. The first connecting portion 501 is connected to the second bending portion 104 of each bending edge and the front reinforcing rib 6, respectively. The second connecting portion 502 is connected to the four supporting reinforcing ribs 2, respectively. In a preferred embodiment, a third connecting portion 503 is also formed on the inner periphery of the second connecting portion 502. The third connecting portion 503 extends directly below the light strip 7 and covers the bottom of the light strip 7, thereby preventing the light from the light strip 7 from directly illuminating the bottom, so as to improve the visual comfort inside the elevator car.

[0037] In one embodiment, the first connecting part 501, the second connecting part 502, and the third connecting part 503 are integrally formed, particularly as integrally formed sheet metal parts. When the heights of the first connecting part 501, the second connecting part 502, and the third connecting part 503 are inconsistent, the first connecting part 501 and the second connecting part 502 are connected by bending transition, and the second connecting part 502 and the third connecting part 503 are connected by bending transition. The first connecting part 501 is respectively riveted to the second bending part 104 of each bending edge and the front reinforcing rib 6 by screws. The second connecting part 502 is respectively riveted to the four supporting reinforcing ribs 2 by screws. The number and type of screws can be adjusted according to actual needs, which will not be elaborated here.

[0038] In one embodiment, each of the supporting reinforcing ribs 2 is a C-shaped bent tube, and the opening side of each supporting reinforcing rib 2 is set outward. The specific shape of the C-shaped bent tube can refer to various forms in the prior art, which will not be described in detail here. Specifically, the opening of the supporting reinforcing rib 2 is set towards the side of the corresponding bent part or the front reinforcing rib 6. On the one hand, the C-shaped bent tube can reduce the overall structural weight of the car roof. On the other hand, the interior of the C-shaped bent tube can form a storage space for accommodating wires, thereby facilitating wiring.

[0039] This utility model also discloses an elevator car, including the aforementioned car top ceiling assembly structure.

[0040] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
