Each car wall unit 1 includes a car wall panel 11 and a connecting portion 12 provided on the car wall panel 11. The connecting portion 12 is provided with a bolt hiding groove 10 with its front opening facing the inside of the elevator car. In two adjacent car wall units 1, a connecting portion 12 of one car wall unit 1 abuts against a connecting portion 12 of the other car wall unit 1 and is fixedly connected by a bolt assembly 3. The two ends of the bolt assembly 3 are respectively hidden in the bolt hiding grooves 10 of the two abutting connecting portions 12. The car wall cover 2 is provided on the two abutting connecting portions 12 and is provided to close the front ends of the two adjacent bolt hiding grooves 10. The car wall cover 2 is fastened to the connecting portion 12.
[0031] In this embodiment, by providing bolt concealment grooves 10 with openings facing the inside of the elevator car on the connecting portion 12 of the car wall unit 1, workers can operate the bolt assembly 3 from inside the elevator car without having to perform high-altitude operations outside the elevator car, reducing installation difficulty and time, while avoiding the risk of workers falling and improving construction safety. Furthermore, the car wall cover 2 covers the two abutting connecting portions 12 and closes the two adjacent bolt concealment grooves 10, preventing the bolt assembly 3 from being exposed, making the elevator car's appearance cleaner and more aesthetically pleasing.
[0032] In this embodiment, the top view of the connecting part 12 is U-shaped. The connecting part 12 includes a snap-fit connecting plate 121, a back connecting plate 122, and a fixed connecting plate 123 connected in sequence. The snap-fit connecting plate 121 is connected to the car wall panel 11. The snap-fit connecting plate 121, the back connecting plate 122, and the fixed connecting plate 123 form the bolt hiding groove 10. The fixed connecting plates 123 of the two connecting parts 12 that abut against each other are fixed by the car wall bolt assembly 3.
[0033] In this embodiment, each car wall unit 1 has two connecting parts 12, which are located at the left and right ends of the car wall panel 11 respectively. The back of the car wall panel 11 and the fastening connecting plates 121 of the two connecting parts 12 enclose each other to form a wall panel groove 100 located on the outside of the elevator car. The upper end and lower end of the wall panel groove 100 are closed by an upper end cap 4 and a lower end cap 5 respectively. The upper end cap 4 is used to connect the top of the elevator car, and the lower end cap 5 is used to connect the bottom of the elevator car. The upper end cap 4 and the lower end cap 5 are connected to the car wall panel 11 and the fastening connecting plate 121 by welding or bolting. Welding is preferred. The upper end cap 4 and the lower end cap 5 can improve the structural stability between the car wall panel 11 and the connecting parts 12. Furthermore, the upper end cap 4 and the lower end cap 5 are provided with vertical connecting holes 45. Specifically, the upper end cap 4 and the lower end cap 5 are riveted with second riveting nuts.

Preferably, the fastening screw holes are formed by the screw holes of the first riveting nut riveted to the fastening connecting plate 121, thereby facilitating the formation of the fastening screw holes. Furthermore, to facilitate the fastening and engagement with the fastening groove 23, the fastening groove 23 is a barbed groove that extends backward and downward at an angle.
[0037] In this embodiment, the top rear side and / or bottom rear side of the cover plate 22 is provided with an avoidance cut 24. The avoidance cut 24 prevents the top rear side and bottom rear side of the cover plate 22 from interfering with the car top and car bottom respectively during the assembly of the car wall cover 2, thus ensuring the smooth progress of the assembly process.
[0038] In this embodiment, the fixed connecting plate 123 is provided with a horizontal connecting hole 1231. The bolt assembly 3 includes a connecting bolt 31 and a connecting nut 32. The head of the connecting bolt 31 is located in one of the bolt concealment grooves 10. The screw end passes through the corresponding horizontal connecting holes 1231 on the two fixed connecting plates 123 and is threadedly engaged with the connecting nut 32 located in the other bolt concealment groove 10. Tightening the connecting nut 32 can fix the mutually fitted fixed connecting plates 123 together. Furthermore, the bolt assembly 3 also includes a spring washer and two flat washers fitted on the screw portion of the connecting bolt 31. The two flat washers are respectively located in two adjacent bolt concealment grooves 10 and are respectively attached to the two fixed connecting plates 123.
