[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figure 1-8 The image shows a ceiling structure for a right-angle double-door elevator car according to this embodiment. This ceiling structure is arranged on the top of the elevator car and is adapted to the right-angle double-door elevator car. The ceiling structure includes an upper frame 1, a lower cover plate 2, a movable plate 3, a first lighting device 4, and a second lighting device 5. The upper frame 1 is formed by eight sets of frame edges connected end-to-end to form an octagonal structure. The frame edges of each upper frame 1 are fixed together by welding.

[0030] The lower cover plate 2 is formed by bending sheet metal. Two sets of lower cover plates 2 are spaced apart and cover the bottom of the upper frame 1, forming a safety window area 6 that communicates with the interior of the upper frame 1. This safety window area 6 allows access to the interior of the upper frame 1. The aforementioned lower cover plate 2 has a trapezoidal structure and is fixed to the upper frame 1 with screws. In the specific structural design, supporting profiles 11 are connected between the frame edges on opposite sides of the upper frame 1. The lower cover plate 2 and the supporting profiles 11 are fixed together with screws, thus achieving a secure connection between the lower cover plate 2 and the supporting profiles 11.

[0031] The outer edge of the lower cover plate 2 is flush with the outer edge of the upper frame 1 to make the visible surface of the suspended ceiling structure flat and aesthetically pleasing. The aforementioned movable plate 3 overlaps between the lower cover plates 2 on both sides and covers the safety window area 6. A reinforcing plate 33 is arranged on the movable plate 3 to improve its structural strength. Light-transmitting holes 31 are distributed on the movable plate 3 to allow light to pass through. A light-transmitting plate 32 is installed on the movable plate 3 to cover the light-transmitting holes 31. The light-transmitting plate 32 is made of acrylic sheet and is arranged on the top surface of the movable plate 3 to be concealed. The two ends of the aforementioned movable plate 3 overlap with the frame edges of the upper frame 1 to achieve complete coverage of the safety window area 6.

[0032] In this embodiment, baffles 22 extending along their length are installed on the back of the two sets of lower cover plates 2. The movable plate 3 is confined between the baffles 22 on both sides to improve the stability of the overlap of the movable plate 3.

[0033] The aforementioned first lighting device 4 is installed above the movable plate 3 and is fixedly connected to the upper frame 1 via a bracket. The first lighting device 4 is a strip light fixture; the light emitted by the first lighting device 4 is projected through the light-transmitting plate 32 and the light-transmitting hole 31, illuminating the interior of the car. In this embodiment, there is a clearance between the aforementioned first lighting device 4 and the movable plate 3 to allow the movable plate 3 to move upwards, so that the movable plate 3 can be raised upwards without being obstructed by the first lighting device 4, thereby enabling the opening of the safety window area 6.

[0034] In this embodiment, a plurality of mounting holes 21 are machined on the lower cover plate 2. A second lighting device 5 is installed in the mounting holes 21. The second lighting device 5 is a downlight to illuminate the interior of the car.

[0035] In this embodiment, the aforementioned movable plate 3 comprises several sub-structures. Each sub-structure overlaps between the lower cover plates 2 on both sides, and is sequentially joined end-to-end along the length of the lower cover plates 2 to form the movable plate 3. At least a portion of the movable plate 3 is provided with the aforementioned light-transmitting holes 31 and light-transmitting plates 32. In this embodiment, there are two sub-structures, and each sub-structure is lifted to achieve disassembly of each sub-structure.

[0036] In practical use, the movable plate 3 is lifted from inside the car or from the top of the car and moved away from the lower cover plate 2 to remove it, thereby opening the safety window area 6 and allowing for the removal and replacement of the first lighting device 4. In this method, the two sets of lower cover plates 2 cover the bottom surface of the upper frame 1, and the movable plate 3 overlaps between the lower cover plates 2 on both sides, which does not damage the visible surface of the car ceiling, ensures the lighting effect, has an aesthetically pleasing overall structure, and allows the ceiling to be opened from both inside and outside the car, effectively meeting the actual usage needs of the elevator and demonstrating strong practicality.
