[0002] As the core component of an elevator that carries passengers or goods, the elevator car's operational stability, noise level, and functional adaptability directly affect the riding experience and safety. With people's increasing demands for comfort in their living and working environments, the requirements for noise control, floor stability, and additional functions during elevator operation are becoming increasingly prominent.

[0003] A search revealed existing technology (application number: CN206969961U), which describes a "silent structure for a home elevator car." This utility model includes a car top, car walls, and a car bottom. The car walls include an inner car wall panel and an outer car wall panel. Between the outer car wall panel and the inner car wall panel, a sound-absorbing cotton layer, a reinforcing layer, and a sound-insulating felt layer are sequentially arranged. The reinforcing layer includes multiple reinforcing ribs, with a density board between adjacent reinforcing ribs. The left and right sides of the density board have grooves arranged in a grid pattern. The sound-absorbing cotton layer includes a sound-absorbing cotton body. One side of the sound-absorbing cotton body has sound-absorbing cotton protrusions corresponding to the grooves, and the other side of the sound-absorbing cotton body has a set of arc-shaped protrusions.

[0004] However, while existing technologies can improve the quietness of the car, they still have some shortcomings: existing technologies have obvious limitations in functionality. This device adds ventilation and floor buffering on the basis of a quiet structure to meet usage requirements. Utility Model Content

[0031] Example 1

[0032] like Figures 1 to 4As shown, this embodiment provides an elevator car with a silent structure, including: an elevator shaft 1 for supporting components; a lifting component including a guide rail 2 arranged on the elevator shaft 1, a car frame 3 slidably connected to the guide rail 2, and guide shoes 4 arranged on both sides of the car frame 3, with the guide shoes 4 slidably connected to the guide rail 2; a sound insulation component including a car body 6 installed on the car frame 3, wherein the car body 6 is configured as a three-layer structure, and the innermost layer of the car body 6 is a decorative layer 63; a ventilation component including an air inlet 7 opened on the top of the car body 6, and a filter screen 8 slidably connected to the car body 6; a buffer component including a rubber pad 12 arranged on the elevator shaft 1; and an extension component including a folding plate 14 hinged to the decorative layer 63.

[0033] Understandable Figure 1 The elevator car is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 The limitations mean that the elevator car can also include, compared to Figure 1 More or fewer parts.

[0034] Furthermore, in this embodiment, the lifting assembly slides on the guide rail 2 via the guide shoe 4 to drive the car frame 3 and car body 6 to rise and fall, the sound insulation assembly blocks noise through the multi-layer car body 6, the ventilation assembly ventilates through the air inlet 7 and is filtered by the filter screen 8, the buffer assembly cushions the impact through the rubber pad 12, and the expansion assembly expands the space by unfolding the folding plate 14; thus realizing the lifting function of the elevator car, while reducing operating noise, maintaining internal ventilation, cushioning the stopping impact, and expanding the usable space.

[0035] Specifically, the lifting assembly includes a steel wire rope 5, which is arranged on the top of the car frame 3.

[0036] In this embodiment, the steel wire rope 5 is pulled by an external force, which drives the car frame 3 and the connected components to rise and fall along the guide rail 2; it provides power traction for the elevator car to rise and fall, and ensures the stability of the rising and falling process.

[0037] Specifically, the sound insulation component includes: a structural layer 61, which is arranged on the outermost layer of the car body 6; and a sound-absorbing layer 62, which is arranged between the structural layer 61 and the decorative layer 63.

[0038] As a preferred implementation, the structural layer 61 provides structural strength to the car body 6, the sound insulation layer 62 absorbs and blocks external noise, and the decorative layer 63 optimizes the interior appearance; thereby enhancing the structural stability of the car body 6, improving sound insulation, and enhancing the visual experience inside the car.

[0039] In summary, the sound-absorbing layer 62 is made of damping sound-absorbing felt, a high-density rubber material, which reduces vibration transmission through damping.

[0040] Example 2

[0041] Specifically, the sound insulation component also includes: sound-absorbing cotton 11, which is arranged on the top of the car body 6 and connected to the air inlet 7.

[0042] In this embodiment, when outside air enters through the air inlet 7, the sound-absorbing cotton 11 absorbs the noise generated by the airflow and the noise transmitted from the outside; further reducing the noise during the ventilation process and improving the quietness inside the car.

[0043] Specifically, the ventilation assembly includes: a positioning pin 9, which is slidably connected to the car body 6 and cooperates with the filter screen 8; and a spring 10, one end of which is connected to the car body 6 and the other end of which is connected to the positioning pin 9.

[0044] With this configuration, the spring 10 provides elastic force to engage the positioning pin 9 in the corresponding position of the filter screen 8, thus fixing the filter screen 8; when disassembling, push the positioning pin 9 to compress the spring 10, releasing the filter screen 8 from its fixation; thus achieving quick fixing and disassembly of the filter screen 8, facilitating cleaning or replacement of the filter screen 8.

[0045] Example 3

[0046] Specifically, the buffer assembly includes a protrusion 13, which is arranged on the back side of the car body 6 and cooperates with the rubber pad 12.

[0047] Therefore, when the elevator stops at each floor, the protrusion 13 contacts the rubber pad 12 of the corresponding floor, and the rubber pad 12 deforms to absorb the impact force when the elevator stops at each floor; buffering the impact force when the elevator stops at each floor, reducing vibration and collision damage when stopping, and improving the comfort and safety of riding the elevator.

[0048] Specifically, the extension component includes a stop 15, which is threaded onto the decorative layer 63.

[0049] In this embodiment, when the folding plate 14 is folded up, the stop block 15 prevents the folding plate 14 from continuing to rotate; when the folding plate 14 is unfolded, the stop block 15 can be loosened to release the restriction; the position of the folding plate 14 after being folded up is fixed to prevent the folding plate 14 from shaking and to ensure stable use of the extended space.

[0050] In actual use, the car frame 3 is pulled by the steel wire rope 5 and slides on the guide rail 2. When the elevator is running, the air generated enters the interior of the car body 6 through the air inlet 7 and the filter screen 8. The sound insulation layer 62 set on the car body 6 can effectively reduce the noise of the elevator operation, and the sound insulation cotton 11 is used to reduce the wind noise generated when the air is inlet. When the elevator stops between floors, the rubber pad 12 is squeezed by the protrusion 13 to buffer the elevator. The friction between the rubber pad 12 and the protrusion 13 will not affect the normal operation. When the filter screen 8 needs to be replaced, the locking of the filter screen 8 can be released by pulling the positioning pin 9 outward. The pivot between the folding plate 14 and the decorative layer 63 is damped and can be rotated to the horizontal position. Users can place takeout or mobile phones on it.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
