Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a column assembly 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 provided 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 and rear wall components and the left and right ends of the rear wall components, 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 and rear wall components and the rear wall components. 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, and the decorative cover is snapped between the two abutment plates.

[0004] However, while self-tapping screws offer advantages in terms of efficiency and convenience during initial installation, potential problems gradually emerge during long-term elevator car operation. As an environment frequently subjected to dynamic loads and vibrations, the elevator car makes self-tapping screws more prone to loosening due to prolonged vibration compared to other types of fasteners. This not only affects the stability of the connection between the decorative elements and the rear column but may also lead to increased noise and reduced structural safety. Furthermore, the reusability of self-tapping screws is a significant drawback. During elevator maintenance or renovation, repeated disassembly and reinstallation of decorative elements can easily result in stripped threads and worn threads. This not only increases installation difficulty but also severely impacts the fixing effect and long-term lifespan of the decorative elements, reducing the overall economic efficiency and practicality of the technical solution.

[0026] Reference Figure 1-3 An elevator car support assembly includes a corner column 1 and a car wall clamping component 2. The corner column 1 includes two L-shaped column segments 11 connected together and an inner protrusion 12 protruding at the inner corner between the two column segments 11. A car wall limiting part 13 protrudes from the end of each column segment 11. The car wall clamping component 2 includes a car wall clamping body 21 and two car wall clamping parts 22 respectively located at both ends of the car wall clamping body 21. Each car wall clamping part 22 corresponds to a car wall limiting part 13 of one column segment 11. The corresponding car wall clamping parts 22 and the car wall limiting parts 13 combine to form a car wall clamping groove. One end of the car wall module 100 can be clamped in the car wall clamping groove to complete the elevator car wall module 100. The car wall module 100 is fixed by insertion at one end; the inner protrusion 12 of the column is provided with a column mating groove extending from top to bottom. The column mating groove includes a bolt hidden groove 121 provided in the inner protrusion 12 of the column and a screw protrusion 122 that penetrates the side of the inner protrusion 12 of the column and communicates with the bolt hidden groove 121. The bolt hidden groove 121 is provided with a column nut 3 that can move up and down along the bolt hidden groove 121 to adjust its position. The car wall clamping body 21 is provided with a mating bolt hole corresponding to the screw protrusion 122. A column bolt 4 that is threaded together with the column nut 3 is inserted into the mating bolt hole. After the column bolt 4 is tightened, it and the column nut 3 together lock the car wall clamping member 2 onto the corner column 1.

[0027] In this embodiment, the outer corner between the two column segments 11 is a rounded surface, which reduces the sharp edges on the elevator car and makes the exterior of the elevator car smoother.

[0028] In this embodiment, the top view cross-sectional shape of the column mating groove is "T" shaped, and the cross-sectional width A1 of the bolt concealment groove 121 is greater than the cross-sectional width A2 of the screw protrusion 122, thereby enabling the column nut 3 to be confined within the bolt concealment groove 121.

[0029] In this embodiment, the column nut 3 is a commercially available T-nut. By utilizing the characteristics of the T-nut, during installation, the column nut 3 can be directly inserted from the screw protrusion 122 into the bolt concealment groove 121, and then rotated so that the column nut 3 can be locked in the bolt concealment groove 121 and cannot be rotated further. This T-nut installation method can facilitate the installation of the column bolt 4 assembly in any position and improve installation efficiency.

[0030] In this embodiment, at least two mating bolt holes are provided from top to bottom, and one column bolt 4 is inserted through each mating bolt hole. Each column bolt 4 corresponds to one mating column nut 3, thereby fixing the car wall clamping member 2 with at least two column bolts 4 and column nuts 3 to ensure its installation quality.

[0031] In this embodiment, a washer assembly is fitted on the column bolt 4. The washer assembly is located between the car wall clamping body 21 and the head of the column bolt 4. The washer assembly includes at least a flat washer and a spring washer. The flat washer and the spring washer can reduce the probability of loosening between the column bolt 4 and the column nut 3 and improve the combination stability between the column bolt 4 and the column nut 3.

[0032] In this embodiment, the column assembly further includes a decorative cover 5, which is installed on the car wall clamping member 2 and covers and hides the car wall clamping member 2, the column nut 3 and the column bolt 4, thereby improving the aesthetics of the interior of the car.

[0033] In a preferred embodiment, the car wall clamping member 2 has two clamping buckles 23 protruding on the side opposite to the inner protrusion 12 of the column, and the decorative cover 5 has a decorative buckle 51 protruding on it to form a snap-fit ​​with the clamping buckles 23. There are two decorative buckles 51, and each decorative buckle 51 is corresponding to one clamping buckle 23, thereby improving the fastening quality between the car wall clamping member 2 and the decorative cover 5.

[0034] In a preferred embodiment, decorative edges 52 extend from both ends of the decorative cover 5. The decorative edges 52 at both ends of the decorative cover 5 correspond to the two column bodies 11 respectively. The ends of the decorative edges 52 are configured to press against the car wall module 100 after the decorative cover 5 is snapped onto the car wall clamping member 2. This allows the decorative edges 52 on the decorative cover 5 to apply a certain clamping force to the car wall module 100, thereby improving the installation quality of the car wall module 100.

[0035] As a preferred embodiment, the top view cross-sectional shape of the decorative cover 5 is a concave arc shape with the concave direction facing the inner convex part 12 of the column. This allows the decorative cover 5 to be as close as possible to the corner column 1, reducing the space occupied by the decorative cover 5 inside the elevator car. At the same time, the elastic deformation of the concave arc-shaped decorative cover 5 is better, so that the decorative pressing edge 52 can be pressed more firmly against the inner side of the car wall module 100 to apply clamping force. This design of the decorative pressing edge 52 can also minimize the gap between the decorative pressing edge 52 and the car wall module 100, improving the aesthetics of the elevator car interior.

[0036] In a preferred embodiment, the corner column 1 is made of a first aluminum profile, the car wall clamping member 2 is made of a second aluminum profile, and the decorative cover 5 is made of a third aluminum profile, giving the column assembly the advantages of high structural strength, simplicity, lightness, and ease of processing. Additionally, the corner column 1 has a through-groove 14 located at the connection point of the two column segments 11, which reduces the overall weight of the corner column 1.

[0037] In this embodiment, the end of the decorative cover 5 and the decorative pressing edge 52 are integrally connected by an arc-shaped portion 53. The decorative pressing edge 52 is a straight pressing edge perpendicular to the inner side of the car wall module 100. The end face of the straight pressing edge away from the arc-shaped portion 53 is a pressing plane that presses against the inner side of the car wall module 100. The pressing plane is configured to be parallel or nearly parallel to the inner side plate of the car wall module 100 when pressing against the inner side of the car wall module 100, thereby increasing the contact surface of the decorative pressing edge 52 pressing against the car wall module 100 and ensuring that it applies a clamping force to the car wall module 100.

[0038] In a preferred embodiment, a central clearance groove 200 is provided at the middle position of the end face of the column segment 11. The central clearance groove 200 can avoid the middle part of the side end of the car wall module 100, thereby avoiding the assembly deformation problem caused by the deformation and bulging of the middle part of the side end of the car wall module 100 pressing against the middle position of the end face of the column segment 11.

[0039] In a preferred embodiment, the column body 11 is provided with a car wall corner avoidance groove 300 for avoiding the outer corner of the car wall module 100. The car wall corner avoidance groove 300 is located at the inner corner connection position of the column body 11 and the car wall limiting part 13. The car wall corner avoidance groove 300 is provided through from top to bottom. By avoiding the outer corner of the car wall module 100, the outer corner of the car wall module 100 can be prevented from interfering with the column body 11 and affecting the normal installation of the car wall module 100. Furthermore, after the car wall clamping member 2 is locked onto the inner protrusion 12 of the column by the column bolt 4 and the column nut 3, a car wall corner clearance 400 is left between the car wall clamping member 2 and the side of the inner protrusion 12 of the column to avoid the inner corner of the car wall module 100. By avoiding the inner corner of the car wall module 100 through the car wall corner clearance groove 300, the inner corner of the car wall module 100 can be prevented from interfering with the inner protrusion 12 of the column and the car wall clamping member 2, thus affecting the normal installation of the car wall module 100.

[0040] 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.
