Description

Technical Field

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

[0002] As the primary space for passengers, the design of the elevator car's interior decoration directly impacts its aesthetics, safety, and passenger experience. Traditional elevator car decoration often uses metal plates, wood panels, or composite materials directly fixed to the car's inner walls. While these materials offer some decorative effect, they generally suffer from significant weight and complex installation, increasing the overall load on the elevator system, especially in high-rise buildings and leading to higher energy consumption. Sintered stone, as a new type of decorative material, is gaining popularity due to its unique properties and beautiful appearance. It boasts a rich variety of colors and textures, strong aesthetics and decorative appeal, superior physical properties, high hardness, wear and scratch resistance, strong impact resistance, long service life, a smooth surface, resistance to dirt, water and moisture, and easy cleaning, reducing the workload of daily elevator maintenance. This makes it suitable for the high-frequency use of elevators. Furthermore, sintered stone is highly workable, allowing for customization to meet different elevator design requirements and adapt to various decorating styles. Moreover, sintered stone is non-toxic, harmless, environmentally friendly, and safe, releasing no harmful substances, making it suitable for use in public places. However, existing decorative structures mostly rely on adhesives or bolts for fixation. After long-term use, there is a risk of decorative panels falling off due to aging of the adhesive layer, or loosening due to insufficient connection strength under frequent vibration, which affects the stability of the structure.

[0003] In existing technologies, some decorative panels used in elevator cars are fixed to the elevator car using magnets. For example, the utility model patent with authorization announcement number CN213950290U provides a modular elevator decorative wall, including a main body with wooden nuts built into the upper and lower ends of the back of the main body, and a strong magnet built into the middle of the main body. When installed with the elevator base plate, the strong magnet fits into the elevator base plate, and the upper and lower ends of the elevator base plate have waist holes for positioning with the wooden nuts. The main body is fixed to the elevator base plate by bolts and wooden nuts, reducing production costs. However, the strong magnet and the non-metallic decorative wall are usually still connected by glue. When this type of structure is used to install decorative panels with a certain weight, such as marble slabs or rock slabs, the decorative panels still have the risk of falling off.

[0004] In terms of lighting design, traditional car lighting typically uses independently installed overhead lights or side wall light strips. Such designs require additional interior space, and without additional lampshades, they can easily cause uneven light distribution or glare, affecting visual comfort. Some decorative structures attempt to embed light sources within the decorative panels, but due to the thickness or poor light transmittance of the panels, it is difficult to achieve a uniform and soft lighting effect, while also increasing the complexity and maintenance costs of the decorative structure.

[0005] Therefore, there is an urgent need for an elevator car decoration structure that is lightweight, highly reliable, and capable of efficient light transmission decoration, in order to meet the comprehensive needs of modern elevators for functionality, safety, and aesthetic design.
