[0025] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] See also Figures 2 to 3 , Figure 2 A three-dimensional diagram of the optimal embodiment of the interior trim panel set of the utility model; Figure 3 This is a three-dimensional diagram of the splicing state of the interior trim panel set of the utility model. Figures 2 to 3 As shown, at least one embodiment provides an interior panel set, including: an interior panel body 100 and a support frame 200, one interior panel body 100 corresponds to one support frame 200, the interior panel body 100 is fixed in the elevator car through the support frame 200, when in use, it is necessary to first fix the support frame 200 on the inner wall of the elevator car, and then fix the interior panel body 100 on the support frame 200, and the interior panel body 100 and the support frame 200 are spliced ​​to form an interior panel set for the elevator car. In order to maintain the compression resistance of the interior panel set and also reduce the relative load of the car, the support frame 200 is designed to include a positioning part 201 and a supporting part 202, wherein the positioning part 201 is against the interior panel body 100, and the supporting part 202 is against the inner wall of the car. In addition, the positioning part 201 and the supporting part 202 are integrally formed structures, and both the positioning part 201 and the supporting part 202 are rectangular frames. The supporting part 202 is arranged at the inner contour edge position of one side of the positioning part 201, wherein the width of the positioning part 201 is greater than the width of the supporting part 202, and the thickness of the positioning part 201 is less than the thickness of the supporting part 202. The supporting frame 200 includes a front side and a back side corresponding to the front side, and a sealing pad 500 is arranged on the back side. The front side abuts against one side of the interior panel 100, so that the front area of ​​the supporting frame 200 is larger, that is, the contact area with the interior panel 100 is larger, and the back side area is smaller, that is, the area abutting against the inner wall of the car is smaller, so as to prevent the interior panel 100 from being deformed due to external force during use. Compared with simply increasing the relative width, the width of the supporting part 202 is reduced to reduce the weight while maintaining the support strength.

[0027] In the related art, when the frame and the panel are relatively fixed, only fixing screws are used to fix the two relatively. The screws bear the weight of the panel. In order to maintain the stability of the fixation, more screws are evenly distributed on the frame, which increases the workload of the assemblers. If the number of screws is reduced, it is difficult to achieve the assembly stability of the panel. Therefore, a supporting structure 400 is provided on the front, and part of the supporting structure 400 extends into the interior panel 100. The interior panel 100 is divided into a decorative surface and an assembly surface corresponding to the decorative surface, and the assembly surface is offset from the front. A plurality of grooves are provided on the assembly surface, and part of the supporting structure 400 extends into the grooves. In other words, the interior panel 100 in this embodiment is hung on the supporting frame 200, and is relatively fixed by a relatively small number of screws. The screws in this embodiment only need to be relatively fixed and do not need to bear much weight of the interior panel 100, so the number is relatively small. Moreover, the grooves of the interior panel 100 are directly stuck to the supporting structure 400, which reduces the difficulty of assembly and does not need to calibrate the horizontality with a ruler. Please refer to Figure 4 ,like Figure 4 As shown, Figure 4 The cross-sectional view is a preferred embodiment of the lifting structure of the utility model. The lifting structure 400 includes a lifting short column 401. A buffer capsule 402 is sleeved on the surface of the lifting short column 401. The sealing gasket 500 is a hollow structure, and the sealing gasket 500 and the buffer capsule 402 are interconnected. When the lifting short column 401 is inserted into the groove, the sealing gasket 500 is compressed and the internal gas is squeezed out. In addition, the relative extrusion force between the sealing gasket 500 and the groove allows the interior panel 100 to be temporarily connected to the support frame 200 during assembly, that is, the purpose of installing the elevator car interior panel can be achieved by one person, and no additional staff is required to support and screw the interior panel 100 thereafter, thereby reducing the workload.

[0028] Please continue reading Figure 3 .like Figure 3 As shown, in order to further enhance the supporting strength of the interior decoration panel 100, a diagonal bracing structure 300 is provided on the positioning portion 201 and the supporting portion 202. The diagonal bracing structure 300 includes a plurality of diagonal rods. The diagonal rods are made of the same material as the supporting frame 200. After two adjacent groups of interior decoration panels are spliced ​​together, the two groups of diagonal bracing structures 300 are abutted against each other, and a plurality of diagonal rods are abutted against each other to form a triangular reinforcement structure. After the two interior decoration panels 100 are spliced ​​together, one side of the diagonal rods in the two groups are butt-jointed to form a stable triangular profile with the supporting frame 200, so that when the force acts on the splicing seam position, it will not cause deformation of the car interior decoration panel.

[0029] The utility model also provides an elevator car, comprising a plurality of interior panel groups as described above. After the plurality of interior panel groups are spliced ​​together, the sealing gasket 500 on the back of each panel body is in an expanded state, tightly pressing the elevator assembly surface, so that the smoke at the assembly surface position of the interior panel body 100 will not enter the decorative surface, that is, it can prevent smoke from entering the interior of the elevator from the elevator shaft. In addition, the elevator car has six surfaces, two side surfaces, a front surface, a rear surface, a top surface and a bottom surface. The six surfaces are all provided with interior panel groups, and the connecting seams between each surface are also provided with sealing strips.

[0030] In summary, by providing a stepped support frame 200, its own weight is reduced while maintaining a good supporting effect, thereby reducing the additional load required for the elevator; by providing a lifting structure 400, the difficulty of assembly is reduced, and at the same time, in cooperation with the sealing gasket 500, the sealing strength in the elevator during use is enhanced; by providing a diagonal bracing structure 300, the supporting strength of the car interior panel is further enhanced, so that when the force acts on the joint position, it will not cause deformation of the car interior panel.

[0031] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
