[0002] Vertical elevators are a type of vertical transportation widely used in high-rise buildings. They utilize mechanical devices such as traction machines, steel cables, and guide rails to achieve the vertical movement of the elevator car. The advent of vertical elevators has greatly improved the efficiency of high-rise buildings and the speed of vertical movement of people, providing crucial technological support for the development of high-rise buildings in modern cities. Their convenience and efficiency make them an indispensable component of high-rise buildings, widely used in various locations such as residences, commercial buildings, hospitals, and hotels.
[0003] While vertical elevators bring great convenience to people's daily lives and work, the noise caused by elevator car vibration seriously affects the passenger experience during actual use. During operation, vertical elevators inevitably vibrate due to various factors such as the operation of mechanical parts, friction between guide rails and guide shoes, and collisions when stopping at floors. This vibration not only increases noise inside the elevator car but also transmits it to the passenger side through the outside of the car, affecting passengers waiting for the elevator.
[0004] Therefore, how to overcome the aforementioned shortcomings of existing technologies is a technical problem that all sectors urgently need to solve. Utility Model Content

It should be noted that, as used below, "longitudinal" refers to a direction perpendicular to the horizontal plane, while "transverse" refers to a direction parallel to the horizontal plane.
[0057] The following is combined with Figures 1 to 12 This invention introduces an elevator car (hereinafter referred to as the elevator car) that can reduce noise.
[0058] See Figure 1 The elevator car 10 includes a side panel 11, a floor 12, and a car top 13. The side panel 11, floor 12, and car top 13 enclose a passenger space. The side panel 11 is arranged around the perimeter of the elevator car 10, the floor 12 is located at the bottom of the elevator car 10, and the car top 13 is located at the top of the elevator car 10.
[0059] See also Figures 2 to 10 The side of the side panel 11 facing the elevator shaft is the outer wall of the side panel 11. Specifically, the side panel 11 includes a right side panel 110, a left side panel 120, and a rear side panel 130. The right side panel 110 is located on the left side of the elevator car 10, the left side panel 120 is located on the right side of the elevator car 10, and the rear side panel 130 is located on the rear side of the elevator car 10. The outer wall of the side panel 11 is composed of the outer walls of the right side panel 110, the left side panel 120, and the rear side panel 130. It is worth mentioning that a door frame 14 is provided on the front side of the elevator car 10, and the door frame 14 is used to install the elevator door (not shown).
[0060] The outer walls of the right side panel 110, the left side panel 120, and the rear side panel 130 each have a first protruding portion and a second protruding portion. The first protruding portion extends longitudinally, and the second protruding portion extends laterally.
[0061] The first protruding part can be a connecting structure forming the right side panel 110, the left side panel 120, and the rear side panel 130, or it can be a car wall reinforcing rib 15 provided in the right side panel 110, the left side panel 120, and the rear side panel 130.
[0062] The first and second protruding parts will be explained in detail below, taking the right panel 110 as an example.
[0063] The right side panel 110 includes a first plate 111, a second plate 112, and a third plate 113. The first protruding portion includes: a connection structure 114 between the first plate 111 and the door frame 14; a connection structure 115 between the first plate 111 and the second plate 112; a connection structure 116 between the second plate 112 and the third plate 113; a connection structure 117 between the third plate 113 and the rear side panel 130; and a car wall reinforcing rib 15 disposed on the right side panel 110.
[0064] The top of the right side panel 110 is provided with an upper end cap 16, and the bottom of the right side panel is provided with a lower end cap 17. The second protruding part includes: the flange 161 of the upper end cap 16 and the flange 171 of the lower end cap.
[0065] The first protruding part can be enclosed with the second protruding part to form several square grooves. In other words, the connecting structures 114, 115, 116, 117 and the car wall reinforcing rib 15 can be enclosed with the flanges 161, 171 to form several square grooves. The bottom of each square groove is a flat area 118.
[0066] The structure of the left side panel 120 and the rear side panel 130 is similar to that of the right side panel 110, and will not be described in detail here.
[0067] Those skilled in the art will understand that the outer wall of the side panel 11 has a plurality of flat areas 118, which are located on the right side panel 110, the left side panel 120, and the rear side panel 130, respectively.
[0068] The elevator car 10 provided by this utility model also includes a sound insulation cotton layer, which covers the outer wall of the side panel 11. The sound insulation cotton layer can absorb the noise generated by the elevator car 10 and other components of the elevator during operation, thereby reducing the intensity of the noise that can be perceived inside the elevator car 10 and on the passenger side.
[0069] The sound insulation layer has a first side and a second side. The first side faces the outer wall of the side panel 11 and is connected to the outer wall of the side panel 11. The second side faces away from the outer wall of the side panel 11 and has multiple protrusions and recesses.
[0070] Taking the first plate 111 of the lower right panel 110 as an example, combined with Figure 11 and Figure 12 Introducing the sound insulation cotton layer.
[0071] The sound insulation cotton layer includes multiple independent sound insulation cotton blocks 200. The number of multiple sound insulation cotton blocks 200 is the same as the number of multiple flat areas 118, and they correspond one-to-one with the multiple flat areas 118.
[0072] Each sound-insulating cotton block 200 has a first surface and a second surface. The first surface is attached to its corresponding flat area 118. In other words, a sound-insulating cotton block is disposed in each square groove, and this sound-insulating cotton block 200 is connected to the flat area 118 at the bottom of the square groove. At the same time, the first surface of the sound-insulating cotton block 200 and the flat area 118 are attached and connected to each other. Multiple protrusions 211 and pits 212 are formed on the second curved surface. That is, multiple sound-insulating cotton blocks 200 constitute a sound-insulating cotton layer 200, and the first surfaces of multiple sound-insulating cotton blocks 200 together constitute the first surface of the sound-insulating cotton layer 200, and the second curved surfaces of multiple sound-insulating cotton blocks 200 together constitute the second surface of the sound-insulating cotton layer 200.
[0073] It is worth mentioning that the first area is a flat surface, so the first curved surface can fit tightly with its corresponding flat area 118, thereby absorbing the vibration of the side panel 11.
[0074] In some exemplary embodiments, each sound-absorbing cotton block has four sides, each side being in close contact with a corresponding first protrusion and second protrusion. See also... Figure 11 The four sides of the sound insulation cotton block 200 located on the front side are respectively connected to the flange 161, the connecting structure 114, the car wall reinforcing rib 15, and the flange 171. Figure 11 (Not shown) in close contact. The four sides of the sound insulation cotton block 200 located at the rear are respectively in close contact with the flange 161, the car wall reinforcing rib 15, the connecting structure 115, and the flange 171 (not shown). Figure 11 (Not shown) Close contact.
[0075] In some exemplary implementations, see [reference] Figure 12 The bottom of each protrusion 211 and each recess 212 is curved.
[0076] In some exemplary implementations, see [reference] Figure 12 The second surface of the sound-insulating cotton block 200 also has multiple intermediate portions 213. Each intermediate portion 213 has protrusions 211 on both sides along a first direction and recesses 212 on both sides along a second direction. The first and second directions are perpendicular to each other. That is, each intermediate portion 213 is surrounded by two protrusions 211 located on opposite sides of the intermediate portion 213, and two recesses 212 located on opposite sides of the intermediate portion 213.
[0077] In some exemplary embodiments, the participants 12, a plurality of intermediate portions 213 and a plurality of protrusions 211 formed on the second curved surface of the sound insulation cotton block 200 are alternately distributed along a first direction, and a plurality of intermediate portions 213 and a plurality of pits 212 are alternately distributed on the sound insulation cotton block 200 along a second direction.
[0078] In some exemplary implementations, see [reference] Figure 12 The upper edge of the projection of the two adjacent protrusions 211 along the first direction and the middle part 213 between the two protrusions 211 in the second direction is a concave curve. That is, the upper edge of the projection of each middle part 213 and its two adjacent protrusions 211 in the second direction is a concave curve.
[0079] In some exemplary implementations, see [reference] Figure 12 The upper edge of the projection of two adjacent pits 212 along the second direction and the middle part 213 between the two pits 212 in the first direction is an upward convex curve. That is, the upper edge of the projection of each middle part 213 and its two adjacent pits 212 in the first direction is an upward convex curve.
[0080] The elevator car 10 provided by this utility model also includes a connecting layer, which is located between the first surface of the sound insulation cotton layer 200 and the outer wall of the side panel 11, so that the sound insulation cotton layer 200 can be connected to the outer wall of the side panel 11.
[0081] In some exemplary embodiments, the connecting layer is an adhesive layer, and the adhesive layer completely covers the first surface of the sound insulation cotton layer 200. In other words, the adhesive layer completely covers multiple first surfaces, so that the first surface of each sound insulation cotton block 200 can be tightly bonded to the corresponding flat area 118.
[0082] Another aspect of this utility model also provides an elevator, which uses the elevator car 10 provided by this utility model.
[0083] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and descriptive purposes. It is not intended to be exhaustive, nor to limit the invention to the precise forms disclosed; obviously, many changes and variations are possible in accordance with the foregoing teachings. The exemplary embodiments were chosen and described to explain the specific principles of the invention and its practical application, thereby enabling others skilled in the art to implement and utilize various exemplary embodiments of the invention, as well as their different alternatives and modifications. The scope of the invention is defined by the appended claims and their equivalents.
