Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution for the bottom support mechanism of a beanbag chair:

[0020] according to Figure 1-5 As shown, the device includes a base 1, a backrest 2 that is detachably installed on one side of the top of the base 1, a cavity 3 inside the base 1, a convex block 4 on the top of the cavity 3, and multiple buffers 5 that are equidistantly installed at the bottom of the cavity 3. The tops of the multiple buffers 5 are fixedly connected to the bottom of the convex block 4. Support rods 7 are fixedly installed at the four corners of the top of the convex block 4. Fixing rings 6 are fixedly installed on the top of the four support rods 7. Multiple elastic ribs 8 are fixedly distributed along the ring on the inner wall of the fixing rings 6 and the top of the convex block 4.

[0021] Specifically, the buffer 5 set at the bottom of the convex block 4 and the elastic rib 8 set between the fixing ring 6 and the convex block 4 provide a good cushioning effect when sitting or lying down, improving the comfort of the beanbag chair. At the same time, the combination of the buffer 5 and the elastic rib 8 makes the beanbag chair less prone to deformation compared to traditional sponge cushioning, thus increasing its service life.

[0022] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, multiple insertion holes 12 are equidistantly provided on the top side of the base 1, and multiple insertion rods 15 are fixedly provided at equal intervals on the bottom of the backrest 2. The multiple insertion rods 15 are inserted and connected to the corresponding insertion holes 12.

[0023] The inner walls of multiple insertion holes 12 are provided with retractable positioning posts 13, and the surfaces of multiple insertion rods 15 are provided with positioning holes 16 that are adapted to the positioning posts 13. The positioning posts 13 are inserted into the corresponding positioning holes 16.

[0024] The other end of the multiple insertion rods 15 is placed inside the cavity 3, and a fixed ball is fixedly provided at the other end of the insertion rods 15. A reset spring 14 is nested and connected to the surface of the insertion rods 15. One end of the reset spring 14 is fixedly connected to the cavity wall of the cavity 3, and the other end of the reset spring 14 is fixedly connected to the fixed ball.

[0025] Specifically, by setting the fixed ball, the return spring 14 can be limited to ensure that the return spring 14 is sleeved on the surface of the positioning post 13.

An arc-shaped block 11 is fixedly installed on the telescopic end of the electric push rod 10. The arc-shaped block 11 abuts against the surface of the corresponding fixed ball.

[0027] Specifically, the electric push rod 10 pushes the arc block 11 to move, and the arc block 11 pushes the positioning post 13 to move, so that the positioning post 13 is inserted into the positioning hole 16, which makes it easy to fix the insertion rod 15 inside the insertion hole 12, effectively ensuring the assembly stability between the backrest 2 and the base 1.

[0028] Multiple anti-slip support seats are fixedly installed at equal intervals along a ring at the bottom of the base 1.

[0029] Specifically, the anti-slip support base improves the stability of base 1, and the stability of base 1 improves the stability of the beanbag chair when placed.

[0030] Working principle: When assembling the bottom support mechanism of the beanbag chair, firstly, the insert rod 15 at the bottom of the backrest 2 is manually inserted into the insertion hole 12. Then, the electric push rod 10 is turned on, and the arc block 11 is moved by the electric push rod 10. The arc block 11 squeezes the positioning post 13 into the positioning hole 16, so that the positioning post 13 is inserted into the corresponding positioning hole 16, which makes it easy to fix the insert rod 15 inside the insertion hole 12 and complete the assembly of the backrest 2. Then, sponge or cotton wool is filled on the surface of the support structure to assemble the beanbag chair.

[0031] When using this beanbag chair, the buffer 5 and the fixing ring 6 at the bottom of the convex block 4 work together with the elastic rib 8 between the convex block 4 to provide a good cushioning effect when sitting or lying down, thus improving the comfort of the beanbag chair. It should be noted that the buffer 5 is a commercially available model "MEGI" buffer 5. This application only uses it and does not make any improvements to the buffer 5. It will not be described in detail here.
