When the car body falls or is hit by an object from a height, the first buffer component, the second buffer component, and the transmission component of the reinforcement mechanism can make the first support frame and the second support frame perform multi-stage buffering movements and resist the external force. Under the combined action of this structure, the car body can be effectively reinforced and protected, greatly improving the safety of the elevator car during use, and solving the above-mentioned shortcomings in the technology.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1-5 The elevator car reinforcement structure shown includes:

[0028] The car body 1 has reinforcing mechanisms at both ends;

[0029] The reinforcing mechanism includes four fixed seats 4 located on the four sides of the end of the car body 1. Each of the four fixed seats 4 has a first buffer assembly on its inner side and a second buffer assembly on its outer side.

[0030] The first buffer assembly includes a first sliding cavity 7 disposed on a fixed base 4. A first spring 8 is fixed at the bottom of the interior of the first sliding cavity 7. A first top post 9 is connected to the top of the first spring 8. The top of the first top post 9 extends to the outside of the first sliding cavity 7 and is fixedly connected to the first support frame 21.

[0031] The second buffer assembly includes a second sliding cavity 10 disposed on a fixed base 4. A second top column 11 is slidably connected inside the second sliding cavity 10. The top end of the second top column 11 extends outside the second sliding cavity 10 and is provided with a cavity groove 18. A third spring 19 is fixed at the bottom end inside the cavity groove 18. A movable column 20 is connected to the top end of the third spring 19. The top end of the movable column 20 extends outside the cavity groove 18 and is fixedly connected to the second support frame 22.

[0032] A first support frame 21 is connected between the top ends of the four first buffer components, and a second support frame 22 is connected between the top ends of the four second buffer components. The second support frame 22 is located outside the first support frame 21, and the height of the second support frame 22 is less than the height of the first support frame 21. A transmission component is provided between two adjacent first buffer components and second buffer components.

[0033] The transmission assembly includes a groove 12 located on the top side of the fixed base 4 and between the first sliding cavity 7 and the second sliding cavity 10. A second spring 13 is fixed inside the groove 12 near one end of the second sliding cavity 10. One end of the second spring 13 is connected to a movable block 14. One top end of the movable block 14 is rotatably connected to the first top post 9 via a rotating shaft, and the other top end of the movable block 14 is rotatably connected to the second top post 11 via a rotating shaft, and a second connecting arm 17 is rotatably connected to the second top post 11 via a rotating shaft.

[0035] By setting reinforcing mechanisms at both the upper and lower ends of the car body 1 to form a reinforced frame, the car body 1 can be supported and protected. When the car body 1 falls or is hit by an object from a height, the first support frame 21 can be subjected to external force first. Then, the first support frame 21 can drive multiple first top columns 9 to slide in the first sliding cavity 7 and squeeze the first spring 8 to achieve buffering movement. At the same time, the first top columns 9 can drive the first connecting arm 16 to rotate, so that the first connecting arm 16 drives the movable block 14 to slide in the groove 12 and squeeze the second spring 13 to perform buffering movement again. After that, the movable block 14 can drive the second connecting arm 17 to rotate, so that the second connecting arm 17 drives the second top column 11 to slide in the second sliding cavity 10. Then, the second top column 11 can drive the second support frame 22 to move through the movable column 20 and the third spring 19 to perform buffering movement again. At the same time, the second support frame 22 can be lifted to resist external force. Under the combined action of this structure, the car body 1 can be effectively reinforced and protected, greatly improving the safety of the elevator car during use.

[0038] By setting up the reinforcing frame 6 and the reinforcing rib 5, the connection strength between the fixed seats 4 can be greatly enhanced. Furthermore, by setting up the vertical beam 2 and the horizontal beam 3, a reinforcing skeleton can be formed inside the car body 1, thereby further supporting and reinforcing the car body 1 and greatly improving the protection strength of the elevator car.
