DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0024] Example: See Figure 1 - Figure 6 This embodiment relates to an elevator ceiling and an elevator car roof, which are specifically used to enhance the aesthetics and lighting arrangement of the elevator car while facilitating repair and maintenance, thereby ensuring the long-term safe use of the elevator. Specifically, the main frame 11 and a bottom plate 12 are reversibly connected to the bottom of the main frame 11. The bottom plate 12 includes two symmetrically arranged flaps 13. One side of the flap 13 is hinged to the main frame 11. A fixing frame 14 is provided in the middle of the main frame 11. A fixing stud 15 is provided at the bottom of the fixing frame 14. A notch 16 is provided on the other side of the flap 13 at a position corresponding to the fixing stud 15. The notch 16 is inserted into the fixing stud 15 and is then tightened with a nut 17 to secure it.

[0025] Specifically, in this embodiment, when performing maintenance on the elevator car ceiling, an operator can loosen the nut 17 on one side of the flap 13 to disengage it from the fixing stud 15. The flap 13 can then be opened along the hinge axis. The flap 13 can then be easily flipped over, exposing the lighting fixtures and other equipment inside the ceiling, facilitating inspection and maintenance operations. After inspection, the flap 13 can be restored to its original state by reengaging the notch 16 with the fixing stud 15 and tightening the nut 17. This design simplifies the installation and removal of the ceiling, reduces the complexity of the maintenance process, and improves work efficiency. Through the above-described structural design, the elevator ceiling of the present invention can be flipped within the car, eliminating the need for operators to ascend to the car roof. The car ceiling does not occupy the maintenance space on the elevator car roof, and the car ceiling is easily installed and removed. This method allows only one operator to repair the relevant components within the car ceiling. Installation requires only two people, both inside and outside the car, making the installation easy, reducing the workload, and reducing the waste of manpower and material resources, thus facilitating installation and maintenance.

[0026] The main frame 11 includes first connecting frames 21 on the front and rear sides and second connecting frames 22 on the left and right sides. The ends of the first connecting frames 21 and the second connecting frames 22 are staggered and overlapped, with the upper folded edge of the second connecting frames 22 positioned above the first connecting frames 21. Specifically, during installation, the first connecting frames 21 on the front and rear sides and the second connecting frames 22 on the left and right sides are initially positioned by staggered overlap. Welding, rivets, or other fastening methods can then be used at the overlaps to reinforce the connection. The main frame 11 of the present utility model is designed with a high degree of dimensional flexibility. The first and second connecting frames 21, 22 can be customized to suit different elevator car sizes, creating frame combinations of varying specifications. By designing first and second connecting frames 21, 22 of varying sizes, the main frame 11 can be easily assembled to accommodate various car sizes, ensuring that the suspended ceiling precisely matches the required elevator car dimensions. Furthermore, this modular design facilitates production and installation, reducing production cycle time and costs, further enhancing the market adaptability of the present utility model.

[0027] The base plate 12 also includes a central main light panel 31, equipped with three sets of downlight slots 32. Downlights of corresponding types and brightness levels can be installed as needed, providing uniform lighting and enhancing the aesthetics and practicality of the elevator car interior. Spring clips 33 are located on both sides of the main light panel 31. The flap 13 has a bent portion 34 with slots 35 that fit snugly within the spring clips 33. Specifically, the spring clips 33 elastically snap into the slots 35 of the bent portion 34 of the flap 13, securing the main light panel 31 to the ceiling structure. This simplifies installation, allowing the panel to be secured with a simple press and snap action, eliminating the need for additional bolts 52 or tools. This significantly reduces installation time and improves maintenance convenience. To replace or maintain the lamp, operators simply press inward on both sides of the main light panel 31, causing the spring clips 33 to retract and remove the main light panel 31.

[0028] See also Figure 5In this embodiment, a light-transmitting panel 41 is positioned above the base plate 12. The light-transmitting panel 41 is positioned between the hinge of the flap 13 and the bent portion 34. A limiting protrusion 42 is positioned on the side of the bent portion 34 opposite the slot 35. When maintenance is required on the elevator ceiling, the flap 13 can be flipped open along the hinge axis. During this process, the limiting protrusion 42 plays a crucial role, effectively supporting one side of the light-transmitting panel 41 and preventing it from sliding under the influence of gravity when the flap 13 is opened. This prevents accidental damage or injury caused by the light-transmitting panel 41 falling off. Furthermore, the provision of the light-transmitting panel 41 not only improves the light transmittance within the elevator car but also enhances the aesthetics of the ceiling. The light-transmitting panel 41 softly scatters light into the cabin through a uniformly distributed light source, creating a comfortable lighting effect. Furthermore, in conjunction with the main light panel 31 and the downlight trough 32, it further enhances the visual experience within the elevator.

[0029] The flap 13 is provided with two groups of rectangular light troughs 43 and diamond-shaped light troughs 44 symmetrically arranged on both sides of the rectangular light troughs 43. By providing the rectangular light troughs 43 and the symmetrical diamond-shaped light troughs 44, light is transmitted from the rectangular light troughs 43 and the diamond-shaped light troughs 44 through the light-transmitting plate 41. As auxiliary light troughs, they form a symmetrical layout with the downlight troughs 32 on the main light panel 31, and can be used to install decorative lamps or auxiliary lighting sources, thereby creating a more layered and three-dimensional visual effect in addition to functional lighting. The first connecting frame 21 and the second connecting frame 22 are both provided with air-conditioning outlets 45, so that the air in the elevator car can be evenly distributed through the ceiling structure, achieving more reasonable ventilation and air-conditioning air flow guidance. The air-conditioning outlets 45 are located on the periphery of the ceiling, which can avoid direct blowing of cold air and provide passengers with a better riding experience.

[0030] In addition, the present invention also provides an elevator car roof including the above-mentioned elevator ceiling, further including a top cover 51, the main frame 11 is connected and fixed to the top cover 51 by bolts 52 and nuts 17, and a spring 53 is provided on the bolt 52 at the connection between the upper folded edge of the second connecting frame 22 and the top cover 51. Figure 6 The top cover 51 is connected to the main frame 11 through bolts 52 and nuts 17, ensuring the stability and safety of the entire ceiling structure and effectively enhancing the overall structural strength of the elevator car roof. The spring 53 mounted on the bolt 52 can form an axial pre-tightening force between the bolt 52 and the nut 17 between the top cover 51 and the main frame 11. On the one hand, it can effectively absorb the vibration generated by the car during operation. At the same time, the pre-tightening force can reduce the loosening of the nut 17 and improve the connection stability. In addition, when the elevator car roof needs to be inspected and repaired, the operator only needs to unscrew the nut 17 to easily remove the ceiling, without having to dismantle the entire ceiling structure, reducing the labor intensity of the operator and saving maintenance time.
