Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a car wall module installation structure applied to an elevator car. Background Technology

[0002] With the development of technology, modular elevator cars are becoming increasingly popular.

[0003] Referring to the technical solution disclosed in application number 202311254150.0, a modular elevator car is provided. In this technical solution, first decorative parts are detachably installed on the inner right-angle sides of the two rear columns facing the center of the car. The left and right sides of the two first decorative parts respectively cover the rear end of the corresponding side rear wall component and the left and right ends of the rear wall component, thereby sealing the assembly gap and improving the aesthetics. In this structure, the first decorative part at the right angle of the rear column includes a limiting pressure strip and a decorative cover. The limiting pressure strip includes two abutment plates that are respectively attached to the vertically arranged side rear wall component and the rear wall component. The two abutment plates are connected into an integral structure by a horizontal base plate. The horizontal base plate is connected to the rear column by self-tapping screws. The decorative cover is snapped between the two abutment plates, effectively sealing the groove on the side of the limiting pressure strip facing away from the rear column. This not only hides the self-tapping screws used to fix the limiting pressure strip, further improving the aesthetics of the elevator car, but also helps to reduce the accumulation of dust and debris and keep the interior of the car clean.

[0004] However, while the decorative cover contributes to both aesthetics and practicality, its design still has some shortcomings. For example, the ends of the decorative cover are flush with the ends of the two abutment plates, meaning that the cover cannot completely cover the abutment plates, leaving some visual imperfections and affecting the overall aesthetic effect. This design deficiency is particularly prominent today, especially given the increasingly stringent requirements for interior decoration details in elevator cars. Furthermore, the decorative cover's function is relatively singular, primarily serving a decorative purpose, and it cannot apply pressure to the car walls, thus failing to enhance the stability of the car wall installation.

[0027] Reference Figure 1-3 A car wall module installation structure for use in an elevator car includes a car wall module 1 and a column assembly. The side end of the car wall module 1 that mates with the column assembly is a car wall mating end 10. The column assembly includes a corner column 2, a car wall clamping member 3, and a decorative cover 4. The corner column 2 includes two column segments 21 connected in an L-shape and an inner column protrusion 22 protruding at the inner corner between the two column segments 21. Each column segment 21 mates with one car wall mating end 10 of one car wall module 1. The column segment 21 is provided with a car wall insertion position for inserting the car wall mating end 10. The car wall insertion position includes a side car wall limiting surface 101 corresponding to the side end face of the car wall mating end 10 and an outer car wall limiting surface 102 corresponding to the outer side edge of the car wall mating end 10.

[0028] Furthermore, the top view of the car wall clamping member 3 is “︺” shaped. The car wall clamping member 3 is installed on the inner protrusion 22 of the column. The car wall clamping member 3 is provided with two inner car wall limiting surfaces 103 corresponding to the inner side edge of the car wall mating end 10. The two inner car wall limiting surfaces 103 are arranged perpendicularly to each other.

[0029] Furthermore, the decorative cover 4 is installed on the car wall clamping member 3 and surrounds the car wall clamping member 3. The decorative cover 4 has decorative pressing edges 41 extending from both ends. The decorative pressing edges 41 at both ends of the decorative cover 4 press against the inner sides of the two car wall mating ends 10 respectively, so that the decorative cover 4 can also apply a certain clamping force to the car wall mating ends 10, thereby further improving the installation quality of the car wall module 1.

[0030] In this embodiment, the car wall clamping member 3 is installed on the inner protrusion 22 of the column using a bolt assembly. The bolt assembly is concealed by a decorative cover 4, thus preventing the bolt assembly from being exposed and improving the aesthetics of the car interior. Furthermore, the inner protrusion 22 of the column is provided with a column mating groove extending from top to bottom. The top view cross-sectional shape of the column mating groove is "T" shaped. The column mating groove consists of a bolt concealment groove 221 and a screw protrusion 222 connected in sequence. The cross-sectional width A1 of the bolt concealment groove 221 is greater than the cross-sectional width A2 of the screw protrusion 222. The bolt assembly includes a column bolt 5 and a column nut 6. The clamping member body is provided with a mating bolt hole corresponding to the screw protrusion 222. The column nut 6 is located within the bolt concealment groove 221. The screw section of the column bolt 5 passes through the mating bolt hole and the screw protrusion 222 and then threadedly engages with the column nut 6. After tightening the column bolt 5, the car wall clamping member 3 is fixed to the corner column 2.

[0031] In this embodiment, the column nut 6 is a T-nut. By utilizing the characteristics of the T-nut, during installation, the column nut 6 can be directly inserted from the screw protrusion 222 into the bolt concealment groove 221, and then the column nut 6 can be rotated so that it can be locked in the bolt concealment groove 221 and cannot be rotated further. This T-nut installation method can facilitate the installation of the bolt assembly in any position and improve installation efficiency.

[0032] In this embodiment, the decorative cover 4 is snapped onto the car wall clamping member 3. Specifically, the side of the car wall clamping member 3 facing away from the inner protrusion 22 of the column is a clamping member groove 31. Two symmetrically arranged clamping buckles 32 are protruding in the clamping member groove 31. The decorative cover 4 is provided with a decorative buckle 42 that forms a snap-fit ​​with the clamping buckle 32. There are two decorative buckles 42, and each decorative buckle 42 is corresponding to one clamping buckle 32, thereby improving the fastening quality between the car wall clamping member 3 and the decorative cover 4. Moreover, the car wall clamping member 3 and the decorative cover 4 are combined together by snap-fit, which is simple in structure and easy to disassemble and assemble.

[0033] As a preferred embodiment, the top view cross-sectional shape of the decorative cover 4 is a concave arc shape with the concave direction facing the inner convex part 22 of the column. This allows the decorative cover 4 to be as close as possible to the corner column 2, reducing the space occupied by the decorative cover 4 inside the elevator car. At the same time, the elastic deformation of the concave arc-shaped decorative cover 4 is better, so that the decorative pressing edge 41 can be pressed more firmly on the inner side of the car wall mating end 10 to apply clamping force. This design of the decorative pressing edge 41 can also minimize the gap between the decorative pressing edge 41 and the car wall module 1, improving the aesthetics of the elevator car interior.

[0034] In this embodiment, the end of the decorative cover 4 and the decorative pressing edge 41 are integrally connected by an arc-shaped portion 43. The decorative pressing edge 41 is a straight pressing edge perpendicular to the inner side of the car wall mating end 10. The end face of the straight pressing edge away from the arc-shaped portion 43 is a pressing plane 411 that presses against the inner side of the car wall mating end 10. The pressing plane 411 is configured to be parallel or nearly parallel to the inner side plate of the car wall mating end 10 when pressing against the inner side of the car wall mating end 10, thereby increasing the contact surface of the decorative pressing edge 41 pressing against the car wall mating end 10 and ensuring that it applies clamping force to the car wall module 1.

[0035] In a preferred embodiment, a central clearance groove 104 is provided at the middle position of the side car wall limiting surface 101. The central clearance groove 104 divides the side car wall limiting surface 101 into two side car wall limiting surfaces. The central clearance groove 104 can avoid the middle part of the car wall mating end 10, thereby avoiding the assembly deformation problem caused by the deformation and bulging of the middle part of the car wall mating end 10 pressing against the middle position of the side car wall limiting surface 101.

[0036] In a preferred embodiment, the column body 21 is provided with a car wall corner avoidance groove 105 for avoiding the outer corner of the car wall mating end 10. The car wall corner avoidance groove 105 is located at the connection position of the outer car wall limiting surface 102 and the side car wall limiting surface 101. The car wall corner avoidance groove 105 is provided through from top to bottom. By avoiding the outer corner of the car wall mating end 10 through the car wall corner avoidance groove 105, the outer corner of the car wall mating end 10 can be prevented from interfering with the column body 21 and affecting the normal installation of the car wall module 1. Furthermore, after the car wall clamping member 3 is locked onto the inner protrusion 22 of the column by the bolt assembly, a car wall corner clearance 106 is left between the car wall clamping member 3 and the side of the inner protrusion 22 of the column to avoid the inner corner of the car wall mating end 10. By avoiding the inner corner of the car wall mating end 10 through the car wall corner clearance groove 105, it is possible to prevent the inner corner of the car wall mating end 10 from interfering with the inner protrusion 22 of the column and the car wall clamping member 3, thus affecting the normal installation of the car wall module 1.

[0037] In a preferred embodiment, the car wall module 1 includes a car wall frame 11 and a transparent glass 12 disposed within the car wall frame 11. At least one end of the car wall frame 11 is the car wall mating end 10. Under the action of the transparent glass 12, the outside of the elevator car can be seen from inside the elevator car, improving the riding experience.

[0038] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
