Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator car technology, and in particular to a car wall assembly structure. Background Technology
[0002] As an indispensable vertical transportation tool in modern high-rise buildings, the optimization of elevator functionality and passenger experience has always been one of the core directions of industry development. The elevator car, as the core carrier of passengers or goods, is not only directly related to the safety and stability during operation in its structural design, but its interior aesthetics and cleanliness are also increasingly becoming key factors influencing user experience and meeting the overall architectural style requirements. Especially in scenarios with high requirements for spatial quality, such as commercial complexes, high-end residences, and star-rated hotels, the exterior design of the elevator car has become an important reflection of the competitiveness of elevator products.
[0003] As the main enclosure structure of the elevator car, the rationality of its assembly structure is a core factor determining the overall performance and appearance of the car. In existing technologies, elevator car walls are typically assembled using a splicing structure, where multiple prefabricated wall panels are fixed and spliced together using connecting components to form a complete car sidewall. To ensure the strength and structural stability of the connections, the mainstream connection methods currently rely heavily on rigid connectors such as bolts. Bolts are used to penetrate the connecting lugs or pre-drilled holes in adjacent wall panels to achieve positioning and fixation between the panels.
[0004] However, the aforementioned bolt-connected car wall assembly structure has significant drawbacks in practical applications, the most prominent being the exposed bolts. Due to the lack of effective concealment or hiding mechanisms for the connection points in the existing structural design, the bolt heads and some bolts used to fix the car wall panels are directly exposed inside the car. This exposed design severely impacts the overall aesthetics of the car; the scattered bolts disrupt the integrity and visual uniformity of the car wall surface, giving the interior a rough, industrial feel that is difficult to match the refined and integrated interior design requirements of modern architecture. Utility Model Content

Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0015] See Figures 1-6A car wall assembly structure includes a car wall module 10, a car bottom module 20, and a car top module 30. The car wall module 10 includes two vertical columns 110 spaced apart horizontally, two horizontal beams 120 spaced apart vertically, and a car wall panel 130. The horizontal beams 120 have a first insertion groove 122 on their wall surface facing the car wall panel 130, and the car wall panel 130 is movably inserted into the first insertion groove 122. The vertical columns 110 have a second insertion groove 111 on their wall surface facing the car wall panel 130, and the car wall panel 130 is movably inserted into the second insertion groove. Inside 111; the left and right ends of the crossbeam 120 are fitted and connected to the column 110; the upper and lower ends of the column 110 are connected to the car bottom module 20 and the car top module 30; the car bottom module 20 and the car top module 30 are both provided with cavities 40; the crossbeam 120 is provided with a first connector 60, which is connected to the car bottom module 20 and the car top module 30 and extends into the cavity 40; the column 110 is connected with a second connector 80, which is connected to the car bottom module 20 and the car top module 30 and extends into the cavity 40. In this embodiment, during assembly, the two uprights 110 and the lower crossbeam 120 are first connected to the car bottom module 20. Then, the car wall panel 130 is inserted between the two uprights 110. Next, the crossbeam 120 above the car wall panel 130 is assembled. Finally, the upper car top module 30 is assembled, and the car top module 30 is connected to the uprights 110 and the upper crossbeam 120.
[0016] See Figure 3The crossbeam 120 has a third slot 121 on its wall facing the car bottom module 20 or the car top module 30; the second connector 80 is a bolt, and the bolt head is inserted into the third slot 121; the car bottom module 20 and the car top module 30 have first through holes corresponding to the positions of the second connector 80, and the threaded post of the bolt extends through the first through hole into the cavity 40; the threaded post of the bolt is threadedly connected to a nut 70, and the nut 70 fits against the inner wall of the cavity 40. In this structure, the bolt, which serves as the second connector 80, not only achieves a rigid connection between the column 110 and the car bottom module 20 and the car top module 30, but also achieves a concealed connection effect through scientific structural design. The bolt head is not exposed, but precisely inserted into the third slot 121 of the crossbeam 120 facing the car bottom or car top module. The third slot 121 provides matching accommodation space for the bolt head, and the third slot 121 can constrain the vertical displacement of the bolt by engaging with the bolt head, preventing it from protruding from the structural surface. The threaded post of the bolt passes through the first through holes corresponding to the car bottom and car top modules, extending into the cavity 40 inside both modules, and is finally tightened by the nut 70 threadedly connected to the threaded post, with the nut 70 fitting snugly against the inner wall of the cavity 40. This design of "bolt head hidden in slot, threaded post and nut concealed in cavity", combined with the insertion positioning of the car wall panel 130 through the first insertion slot 122 of the crossbeam and the second insertion slot 111 of the column, replaces the traditional exposed fixing method of through bolts, making all connection structures invisible.
[0017] See Figure 3 The column 110 has threaded holes 112 at both its upper and lower ends. The car bottom module 20 and the car top module 30 have second through holes corresponding to the threaded holes 112, communicating with the cavity 40. The first connector 60 passes through the second through hole and is threadedly connected to the threaded hole 112. The first connector 60 is the core component; after passing through the second through hole communicating with the cavity 40, it is threadedly connected to the threaded holes 112 at the upper and lower ends of the column 110, achieving a stable lock between the column and the foundation module. Simultaneously, the cooperation between the second through hole and the cavity 40 allows the first connector to be completely hidden inside the structure, avoiding exposure and affecting aesthetics, while also ensuring structural stability by reliably transferring the column load through the threaded connection.
[0018] See Figure 3The crossbeam 120 is provided with a mounting hole 123 that communicates with the second insertion slot 111. A positioning member 50 is provided in the mounting hole 123 and inserted into the second insertion slot 111. The positioning member 50 is inserted into the second insertion slot 111 of the column 110 through the mounting hole 123 of the crossbeam 120. With the help of the communication between the mounting hole and the second insertion slot, the relative position of the crossbeam and the column is quickly positioned, preventing misalignment during assembly and laying the foundation for the accurate installation of the second connecting member 80.
[0019] See Figure 3 The positioning element 50 is a stud and is threadedly connected to the mounting hole 123; the crossbeam 120 is provided with an operating channel 124 for connecting the mounting hole 123 and the first insertion slot 122. When the crossbeam 120 and the column 110 are positioned and assembled, a tool can be used to pass through the operating channel 120 and engage with the positioning element 50 for transmission. By rotating the positioning element 50, it is gradually inserted into the second insertion slot 111 under the action of the threaded connection, thereby constraining the relative position of the column 110 and the crossbeam 120 by the positioning element 50 being inserted into the second insertion slot 111.
[0020] See Figure 3 The car bottom module 20 and the car top module 30 include at least a bottom plate 910, a top plate 920 and an outer side plate 930, and the outer side plate 930 is connected to the bottom plate 910 and the top plate 920.
