Description

Technical Field

[0001] This utility model relates to the field of elevator car ceiling technology, specifically to a light-emitting integrated ceiling for the interior of an elevator car. Background Technology

[0002] Traditional car ceilings are often composed of various irregularly shaped profiles, separate light fixtures, and acrylic panels. During installation, it is necessary to first lay load-bearing beams on the car ceiling, and then fix the side profiles, panels, and light fixtures one by one. The whole process is cumbersome, time-consuming, and labor-intensive. At the same time, acrylic panels are prone to dust accumulation, and most light fixtures are externally mounted, requiring the reservation of sockets and light shields. The overall shape is scattered and inconsistent, making it difficult to meet the requirements of rapid installation and overall aesthetics. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] Please see Figures 1 to 4 A preferred embodiment of this application shows a luminous integrated ceiling for use inside a car, comprising an outer frame profile 1, fixing corner pieces 2, and a light-emitting element 3. The outer frame profile 1 is detachably mounted on the car roof, and multiple outer frame profiles 1 form a fixing frame 4. The fixing corner pieces 2 are used to connect and fix adjacent outer frame profiles 1. The light-emitting element 3 is fitted within the fixing frame 4 and includes a base plate 31, a reflective film 32, a light strip 33, and a diffuser plate 34. The reflective film 32 is located below the base plate 31. The light strip 33 is located at the lower edge of the reflective film 32, and a light guide plate 35 is disposed within the light strip 33. The diffuser plate 34 is located below the light guide plate 35.

[0028] According to the embodiment of this utility model, by integrating the light strip 33, the light guide plate 35 and the diffuser plate 34 into the light-emitting body 3, the ceiling can emit light as a whole to ensure the lighting effect. Furthermore, the detachable outer frame profile 1, combined with the snap-fit ​​light-emitting body 3, enables quick installation and removal, significantly improving installation efficiency and reducing labor costs. At the same time, compared with traditional acrylic ceilings, the luminous ceiling is less prone to dust accumulation, the surface is easy to clean, and the design is simple and beautiful.

[0029] The following detailed description uses specific examples:

[0030] Further, please see Figure 1 The fixing frame 4 is equipped with a rubber strip 5 for clamping and fixing the light-emitting element 3. By adding the rubber strip 5 inside the fixing frame 4, the light-emitting element 3 can be elastically clamped, preventing the light-emitting element 3 from loosening and causing noise during vibration or car operation, while improving the overall stability and durability of the ceiling.

[0031] Specifically, please see Figure 1 , 2 In this embodiment, there are four outer frame profiles 1, which together form a rectangular fixing frame 4. The fixing corner piece 2 is L-shaped and is fixed to the outer frame profile 1 using headless hexagonal screws 6. The design of hiding the headless hexagonal screws 6 inside the outer frame profile 1 not only achieves a smooth, protrusion-free appearance but also allows for quick assembly and disassembly using a common hexagonal wrench, facilitating on-site maintenance and replacement.

[0032] Specifically, please see Figure 1 , 2 4. The outer frame profile 1 is equipped with detachable T-bolts 7, which are used to fix the outer frame profile 1 to the car roof. Further, the top of the outer frame profile 1 has an inverted T-shaped limiting groove 11 along its length, within which the head of the T-bolt 7 is movable. The top of the outer frame profile 1 has an oblong opening 12 communicating with the limiting groove 11, through which the head of the T-bolt 7 is inserted. By providing detachable T-bolts 7 on the outer frame profile 1, the entire ceiling is securely fixed to the car roof base. The sliding engagement of the T-bolts 7 with the limiting groove 11 achieves rapid positioning without the need for additional drilling, simplifying the connection process between the ceiling and the car roof and ensuring installation stability. The oblong opening 12 allows for quick installation and removal of the T-bolts 7, thereby improving overall installation efficiency. It should be noted that the width of the remote opening is greater than the size of the head of the T-bolt 7 so that it can be inserted into the limiting groove 11.

[0033] In use, firstly, connect the three outer frame profiles 1 sequentially with fixing corner pieces 2 and tighten them with headless hex screws 6 to form a "U"-shaped fixing frame 4. Then, insert the light-emitting element 3 into the assembled fixing frame 4. Next, align the fourth outer frame profile 1 with the opening of the fixing frame 4 and connect and fix it to the two adjacent outer frame profiles 1 with fixing corner pieces 2 and headless hex screws 6 to complete the closure of the rectangular fixing frame 4. Then, insert the rubber insert 5 into the gap between the fixing frame 4 and the light-emitting element 3 for clamping and fixing. Insert at least two T-bolts 7 into the oval opening 12 on each outer frame profile 1, so that their heads slide into the inverted T-shaped limiting groove 11 on the top of the outer frame profile 1 so that the T-bolts 7 are aligned with the reserved installation holes on the car roof. Tighten the T-bolts 7 to install the entire ceiling on the car roof.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
