[0040] Figure 1 This is a schematic structural diagram of a car floor platform 100 according to an embodiment of the present invention. Figure 2 This is a schematic structural diagram of the first tube beam 60 and the second tube beam 70 according to an embodiment of the present invention. Figure 1 and Figure 2As shown, in one specific embodiment, the car includes a car body and a maintenance device 200. The car body includes a car bottom platform 100, which has a first mounting plate 80, a first tube beam group, a second tube beam group, a second mounting plate 20, and a cover plate 40. The first tube beam group includes a plurality of first tube beams 60 spaced apart along a first direction, and the second tube beam group includes a plurality of second tube beams 70 spaced apart along a second direction. The plurality of first tube beams 60 and the plurality of second tube beams 70 define a plurality of mounting slots 10. The second mounting plate 20 is mounted above the first and second tube beam groups and has a through hole 21 extending vertically through the second tube beam group. The cover plate 40 is mounted at the through hole 21 and is rotatably connected to the second mounting plate 20. The cover plate 40 has a closed state that covers the through hole 21 and an open state that exposes the through hole 21. The maintenance device 200 is installed in a target mounting slot among the plurality of mounting slots 10, with the through hole 21 aligned with the target mounting slot. The maintenance device 200 is used to perform maintenance on the car body. When the car body needs to be inspected, the cover plate 40 is opened; when the car body is running normally, the cover plate 40 is closed.

[0041] This embodiment is equivalent to installing the inspection device 200 inside the car bottom platform 100. By opening the cover plate 40, the car body can be inspected through the inspection device 200. Operators can complete the inspection inside the car body without entering the hoistway pit or car top, making the operation more convenient and safer. Furthermore, the arrangement of multiple first pipe beams 60 and multiple second pipe beams 70 increases the strength of the car bottom platform 100 and also facilitates the installation of the inspection device 200.

[0042] This embodiment can be used not only with conventional car structures, but also with open platform structures that have no car roof or car walls.

[0043] In this embodiment, both the first tube beam 60 and the second tube beam 70 have square cross-sections. In other embodiments, the cross-sectional shapes of the first tube beam 60 and the second tube beam 70 can be determined according to specific design requirements.

[0044] See Figure 2 In some embodiments, multiple first tube beams 60 and multiple second tube beams 70 define nine mounting slots 10. The maintenance device 200 can be installed in one of the mounting slots 10. The position of the through hole 21 of the second mounting plate 20 can be set according to the installation position of the maintenance device 200, and the position of the through hole 21 determines the position design of the cover plate 40.

[0045] Figure 3 This is a schematic structural diagram of a maintenance device 200 according to an embodiment of the present invention, as shown below. Figure 3As shown, in some embodiments, the maintenance device 200 is flat, which reduces its vertical dimensions and thus the vertical dimensions of the car bottom platform 100, making it suitable for small pits. Furthermore, placing the maintenance device 200 on the car bottom platform 100 compresses the counterweight side space of the entire elevator, maximizing the platform or car dimensions for the same shaft size.

[0046] In some embodiments, the maintenance device 200 includes a flat housing 230 and a plurality of control boards 220 arranged side by side, one of which is equipped with a miniature inching switch 210. (See also...) Figure 3 Currently, the standard car top inspection box is quite tall, while the internal space of the car floor platform 100 is insufficient. Therefore, the inspection device 200 needs to be flattened. The original three-dimensional layout of the control panel 220 and other components inside the inspection device 200 is changed to a flat layout. Large mechanical switches and buttons such as inspection switches and emergency stop buttons are eliminated and replaced with miniature momentary switches 210 located on the control panel 220, thereby reducing the height of the inspection device 200. Furthermore, since the inspection device 200 is located inside the car, lighting and other devices can be placed on the car floor control panel.

[0047] In some embodiments, the first and second tube beam assemblies are installed at the middle position of the car bottom platform 100, see [reference]. Figure 2 This embodiment increases the strength of the car bottom platform 100 through the design of the first and second tube beam assemblies.

[0048] In some embodiments, the car also includes a reinforcing plate, which is adhered to the inner side of the cover plate 40 to increase the strength of the cover plate 40. Here, the reinforcing plate can be made of Q235 carbon steel, the same material as the first mounting plate 80 and the second mounting plate 20.

[0049] In some embodiments, to improve the aesthetics of the car platform 100, the car also includes a soft-cover floor 50, which is laid on the second mounting plate 20 and can cover the cover plate 40 and the second mounting plate 20. When maintenance is required, the soft-cover floor 50 can be removed to expose the cover plate 40, allowing operators to open the cover plate 40 and operate the maintenance device 200. Here, the soft-cover floor 50 can be PVC or fabric carpet, etc.

[0050] Figure 4 This is a schematic structural diagram of the reinforcing frame 30 according to an embodiment of the present invention. Figure 5 This is a schematic cross-sectional view of a car floor platform 100 according to an embodiment of the present utility model. Figure 4 and Figure 5As shown, in some embodiments, the car also includes a reinforcing frame 30, which is installed in the target mounting slot and covers the outside of the maintenance device 200, and is spaced at a predetermined distance from the top of the maintenance device 200. When the cover plate 40 is in the closed state, it abuts against the top of the reinforcing frame 30. Alternatively, if a reinforcing plate is attached to the inside of the cover plate 40, then the reinforcing plate abuts against the top of the reinforcing frame 30.

[0051] This embodiment, through the design of the reinforcing frame 30, can further support the cover plate 40, thus preventing the cover plate 40 from deforming under stress and damaging the maintenance device 200. Here, this embodiment fully considers that the car floor platform 100 needs to support the weight of many passengers, which will cause stress and, over time, deformation of the cover plate 40. Therefore, by setting the reinforcing frame 30 under the cover plate 40 to support it, deformation of the cover plate 40 can be prevented, damage to the maintenance device 200 can be avoided, and the service life of the maintenance device 200 can be improved.

[0052] In some embodiments, the reinforcing frame 30 includes a top plate 31 and a plurality of supports 32. The cross-sectional area of ​​the top plate 31 is larger than that of the maintenance device 200, and the cover plate 40 abuts against the top plate 31 when closed. The plurality of supports 32 are arranged vertically below the top plate 31, and are located on the sides of the maintenance device 200, with a height higher than that of the maintenance device 200. It can be understood that the reinforcing frame 30 does not contact the maintenance device 200, thus preventing damage to the maintenance device 200 when the reinforcing frame 30 is under stress. Here, the material of the reinforcing frame 30 can be a high-strength material, which can be selected according to specific design requirements. When the car body needs maintenance, the cover plate 40 is opened first, then the reinforcing frame 30 is removed, and finally the maintenance device 200 is operated. After maintenance is completed, the reinforcing frame 30 is placed back in, and then the cover plate 40 is closed.

[0053] This embodiment also provides an elevator, which includes the car of any of the above embodiments. Details regarding the car are not provided here.

[0054] This embodiment adopts an integrated design of the maintenance device 200 and the car bottom platform 100, which makes the processing simpler and saves costs.

[0055] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
