Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example:

[0018] like Figure 1 and Figure 2 As shown, an adaptive ergonomic sofa includes a sofa frame with two symmetrical mounting plates 20 inside. A backrest 19 is rotatably mounted between the two mounting plates 20, and a seat 16 is movably mounted between the two mounting plates 20. The seat 16 is located on one side of the backrest 19 and can move closer to or further away from the backrest 19 as it rotates. The seat 16 can adjust together with the backrest 19. When the user is in different sitting positions, the seat 16 can maintain a close fit to the user, improving the user's comfort. The side of the seat 16 that contacts the human body is wavy, which makes the seat 16 fit the human body better and improves the user's comfort.

[0019] When a user wants to adjust their sitting posture, they can rotate the backrest 19 to a certain angle and then fix the backrest 19. The backrest 19 then moves the seat 16, and the seat 16 is fixed together with the backrest 19, thus adjusting the distance between the seat 16 and the backrest 19, thereby improving the user's comfort.

[0020] The sofa frame includes a first rod group, a second rod group, and a third rod group. The first rod group includes four vertical first support rods 22. The second rod group includes four horizontal second support rods 21. The first support rods 22 and the second support rods 21 are intermittently connected. The third rod group includes four horizontal third support rods 15. The first support rods 22 and the third support rods 15 are intermittently connected.

[0021] Two reinforcing ribs 36 are fixed between the two third support rods 15. The mounting plate 20 is fixed at one end of the corresponding reinforcing rib 36. The backrest 19 has a first connecting shaft 28 on both ends. The first connecting shaft 28 rotates through the mounting plate 20. A connecting block 34 is fixed at one end of the backrest 19. The two first connecting shafts 28 are fixed at both ends of the connecting block 34.

[0022] One end of the first connecting shaft 28 passing through the mounting plate 20 is fixedly provided with a force-bearing arm 23, and a force-bearing block 25 is fixedly provided on the force-bearing arm 23. A second connecting shaft 29 is rotatably provided on one end of the force-bearing block 25, and a first transmission rod 24 is rotatably provided on one end of the second connecting shaft 29.

[0023] The reinforcing rib 36 has a horizontally penetrating connection port 13. The two ends of the seat plate 16 are fixed with second transmission rods 10. The end of the second transmission rod 10 is provided with a third transmission rod 11. The third transmission rod 11 passes through the connection port 13 and has a third connecting shaft 35 at one end. The third connecting shaft 35 is rotatably connected to the first transmission rod 24.

[0024] A gasket 14 is connected between the reinforcing rib 36 and the parallel third support rod 15. A pneumatic rod 12 is fixed at one end of the gasket 14. The telescopic end of the pneumatic rod 12 is fixedly connected to the third transmission rod 11. When the pneumatic rod 12 is not subjected to external force, the pneumatic rod 12 can push the third transmission rod 11 to move.

[0025] A first contact plate 17 is fixed at the top of the connection between the first support rod 22 and the third support rod 15, and a second contact plate 18 is fixed at the top of the two first contact plates 17 on the same side of the seat plate 16.

[0026] like Figure 3 As shown, both ends of the backrest 19 are fixed with first connectors 32, and hooks are provided on the first connectors 32. Two second connectors 26 that are not on the same horizontal plane are fixed at one end of the third support rod 15 parallel to the reinforcing rib 36. The hook abuts against one of the second connectors 26. The hook includes a ring part 33 connected to the first connector 32, a rod section 31, and a bent part 30 connected to the second connector 26. The bent part 30 extends into different second connectors 26 to fix the backrest in different postures.

[0027] Sponge is glued to the outside of the sofa frame, backrest, and seat according to the shape, and then covered with an outer layer.

[0028] Working principle:

[0029] When the sofa back needs to be adjusted, the bent part 30 is removed from the second connector 26, the backrest 19 is rotated, the backrest 19 drives the force arm 23 to rotate through the first connecting shaft 28, the force arm 23 drives the first transmission rod 24 to move through the force block 25, the first transmission rod 24 drives the third transmission rod 11 to move closer to the pad 14, the pad 14 drives the seat 10 to move through the second transmission rod 10, the bent part 30 is inserted into another second connector 26 to fix the backrest 19 and the seat 10.
