[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] Example 1, please refer to Figure 1-Figure 5 An elevator with a spliced ​​car bottom, the buffer mechanism 4 includes a plurality of arc frames 401 distributed in a ring shape, the top of the arc frame 401 is fixedly connected with a connecting rod 402, the top of the connecting rod 402 is fixedly connected to the bottom end of the car bottom 1, and the arc frame 401 and the first buffer leaf 403 and the second buffer leaf 404 are connected to the car bottom 1 through the connection of the connecting rod 402.

[0039] A first buffer leaf 403 is connected between two adjacent arc frames 401 through a rotating shaft and a coil spring. A second buffer leaf 404 is provided at one end of the first buffer leaf 403. The first buffer leaf 403 and the second buffer leaf 404 can increase wind resistance when the car falls accidentally, thereby improving the overall safety of people in the car when the car falls.

[0040] A rotating rod 405 is interspersed between the second buffer leaf 404 and the first buffer leaf 403, and two slidable movable rings 406 are symmetrically arranged on the rotating rod 405. By arranging the movable rings 406 and the rotating rod 405, the second buffer leaf 404 and the first buffer leaf 403 can be displaced relative to each other but cannot be separated.

[0041] Two folding rods 407 are hinged between the two movable rings 406 , and the ends of the two folding rods 407 are hinged to each other.

[0042] An elastic cloth 408 for generating wind is arranged between the two folding rods 407. By arranging the elastic cloth 408, the wind generated during rotation can pass through the inside of the second buffer leaf 404 and the air pipe 412 through the car bottom 1 into the interior of the car, thereby replacing the air inside the car.

[0043] One end of the second buffer leaf 404 is fixedly connected to an air pipe 412, and one end of the air pipe 412 is fixedly connected to the bottom end of the car bottom 1. By providing the air pipe 412, the space in the car can be replaced and heat can be dissipated.

[0044] A plurality of stirring rods 411 are alternately arranged between the plurality of air pipes 412, and the plurality of stirring rods 411 are distributed in a ring shape at the headquarters at the bottom end of the car platform 1, and the plurality of stirring rods 411 are used to reel in the plurality of air pipes 412 to tilt the second buffer leaf 404 and the first buffer leaf 403. By reeling in the stirring rods 411, the air pipe 412 can drive the second buffer leaf 404 and the first buffer leaf 403 to tilt, thereby adjusting the tilt angle.

[0045] A disc 410 is provided between the plurality of air pipes 412 , and the circumferential side of the disc 410 is fixedly connected to one end of a plurality of stirring rods 411 . By providing the disc 410 , when the output shaft of the motor 409 rotates, the plurality of stirring rods 411 can rotate together.

[0046] The disc 410 is fixedly connected to a motor 409 , which is fixedly installed in the middle of the bottom end of the car platform 1 and is used to drive a plurality of stirring rods 411 to reel in a plurality of air pipes 412 .

[0047] The use process of the splicable elevator car bottom provided by the present invention is as follows:

[0048] First, the car wall is mounted on a plurality of mounting frames 2, and then the car wall is fixed on the car bottom 1 through bolts and car wall connection holes 3;

[0049] During the movement of the car, multiple folding rods 407 and elastic cloth 408 rotate to guide the air into the second buffer leaf 404, and enter the interior of the car through the air pipe 412 for air circulation. When a dangerous situation occurs, the motor 409 drives the multiple stirring rods 411 to rotate and reel in the multiple air pipes 412. The multiple air pipes 412 are pulled to drive the multiple second buffer leaves 404 and the first buffer leaves 403 to tilt. On the whole, the multiple first buffer leaves 403 and the second buffer leaves 404 are trumpet-shaped, which increases the wind resistance and can slow down the falling speed of the car. When it is about to contact the ground, the motor 409 rotates in the direction, and the multiple air pipes 412 return to their original state. At this time, the first buffer leaf 403 and the second buffer leaf 404 rotate, perpendicular to the car bottom 1, and through the folding rod 407 and the elastic cloth 408, when the first buffer leaf 403 contacts the ground, the force between the first buffer leaf 403 and the ground can be reduced, thereby improving safety.
