[0001] The present invention relates to the field of leisure chairs, and in particular to an adaptive adjustment leisure chair. Background Art
[0002] A leisure chair refers to a chair that we usually use to enjoy our leisure time, including folding armchairs, folding swivel chairs, etc. Some users who sit at a desk for a long time often feel soreness in the lumbar spine. Therefore, a lumbar support device is often placed on the leisure chair. The lumbar support device is used to assist the lumbar spine and reduce the gravity of the body borne by the lumbar spine. Since the lumbar support device is not an accessory of the chair itself but an additional functional product, it needs to be tied to the backrest. When the angle of the chair backrest is adjusted, the person sitting on the chair leans on the backrest of the chair, and the angle of the body will also change. However, the lumbar supports in the prior art are all products with a fixed shape, and they cannot change the amplitude of supporting the human waist with the change of the body angle (change of body center of gravity), and cannot be adaptively adjusted by the user according to their sitting posture. For this reason, the present invention proposes an adaptive adjustment leisure chair. Summary of the Invention

[0015] Beneficial effects of the present invention:
[0016] 1. The rotation of the output shaft of the drive motor drives the rotation of two first columns. The rotation of the two first columns drives the rotation of two worm gears. The rotation of the worm gears drives the rotation of the worm wheels. The rotation of the worm wheels drives the rotation of the second column and the backrest plate. The angle between the backrest plate and the seat plate becomes larger / smaller. When the top end of the backrest plate moves towards the seat plate, that is, when the angle between the backrest plate and the seat plate becomes smaller, the rotation of the backrest plate causes the connecting end of the fourth rod and the seat plate to rotate. The other end of the fourth rod pushes the third rod and the first rack to move. The first rack moves away from the seat plate. The first gear interacts with the first rack, and the first gear rotates and drives the third column and the sixth rod. One end of the sixth rod slides relative to the lumbar support and pushes the lumbar support to move out of the storage box. The height of the lumbar support exceeding the back panel plane increases. Thus, when the angle between the back panel and the seat plate becomes smaller, the center of gravity of the user's upper body changes. By increasing the support range of the lumbar support, the pressure on the user's lumbar spine is reduced to adapt to the user's sitting posture;
[0017] Synchronously, the rotation of the backrest plate pulls the fifth rod to move. The fifth rod pulls the second rack to move. The second gear interacts with the second rack, causing the second gear to rotate. The rotation of the second gear drives the rotating plate to rotate. The rotating plate rotates into the first groove, so that the first seat cushion and the second seat cushion are basically on the same plane;
[0018] 2. When the top end of the backrest plate moves away from the seat plate, that is, when the angle between the backrest plate and the seat plate becomes larger, the rotation of the backrest plate causes the connecting end of the fourth rod and the seat plate to rotate. The other end of the fourth rod pulls the third rod and the first rack to move. Each component moves in the opposite direction to before. The lumbar support moves into the storage box, and the height of the lumbar support exceeding the back panel plane decreases. Thus, when the angle between the back panel and the seat plate becomes larger, the center of gravity of the user's upper body changes. The pressure on the lumbar spine is dispersed to other parts of the upper body. The pressure on the lumbar spine is smaller. By reducing the support range of the lumbar support, the comfort of the user is increased to adapt to the user's sitting posture;
[0019] Synchronously, the rotation of the backrest plate pushes the fifth rod to move. The fifth rod pushes the second rack to move. The second gear interacts with the second rack, causing the second gear to rotate. The rotation of the second gear drives the rotating plate to rotate. One end of the rotating plate moves away from the first groove, and the first seat cushion of the rotating plate tilts up. Thus, when the angle between the back panel and the seat plate becomes larger, the rotating plate and the first seat cushion support the bottom of the user's thigh to prevent the user from sliding down;
[0020] Through the above steps, the present invention solves the problem in the prior art that the lumbar support cannot change the amplitude of supporting the human waist as the angle of the human body changes and cannot be adjusted adaptively according to the user's sitting posture.

The first support cushion 15 is for expanding the range for supporting the placement of the user's legs.
[0040] Embodiment 4
[0041] On the basis of Embodiment 3, a fixing device 19 is provided on one side of an armrest 10. The fixing device 19 includes a fixing plate 20. Two arc-shaped elastic pieces 21 are fixedly connected to the bottom of the fixing plate 20. The fixing device 19 is used to place a crutch, and the handle of the crutch can be stuck between the two arc-shaped elastic pieces 21. A control panel 4 is provided on one side of the other armrest 10. A driving motor 35 is fixedly connected to the bottom of the seat plate 5. The driving motor 35 is a servo motor. Two first columns 36 are rotatably connected to the bottom of the seat plate 5. The two first columns 36 are respectively connected to two worm gears 37 through bevel gears. The output shaft of the driving motor 35 is connected to the two first columns 36 through bevel gears. The control panel 4 and the driving motor 35 are electrically connected. Support seats 6 are fixedly connected to both sides of the bottom of the seat plate 5. A partition 7 is slidably connected between the two support seats 6. The partition 7 and the support seats 6 each include two support legs 17 fixedly connected to the bottom of the seat plate 5. Two reinforcing bars 18 are fixedly connected between the two support legs 17. The partition 7 is slidably connected to the two reinforcing bars 18. Heating devices are provided in the first seat cushion 8, the second seat cushion 12, and the backrest 1, and heating and heating can be performed. A plug or a power supply is provided at the bottom of the seat plate 5, and the plug can be connected to an external power supply to energize the electrical components on the chair.
[0042] Working principle: The user sits on the chair and adjusts the control panel 4. The control panel 4 can control the driving motor 35 to work. The output shaft of the driving motor 35 rotates to drive the two first columns 36 to rotate. The two first columns 36 rotate to drive the two worm gears 37 to rotate. The worm gear 37 rotates to drive the worm wheel 32 to rotate. The worm wheel 32 rotates to drive the second column 38 and the backrest 2 to rotate. The angle between the backrest 2 and the seat plate 5 becomes larger / smaller. When the top end of the backrest 2 moves towards the direction close to the seat plate 5, that is, when the angle between the backrest 2 and the seat plate 5 becomes smaller, the rotation of the backrest 2 causes the connecting end of the fourth rod 27 and the seat plate 5 to rotate. The other end of the fourth rod 27 pushes the third rod 26 and the first rack 25 to move. The first rack 25 moves away from the seat plate 5. The first gear 41 interacts with the first rack 25. The first gear 41 rotates and drives the third column 42 and the sixth rod 44. One end of the sixth rod 44 slides relative to the lumbar support 3 and pushes the lumbar support 3 to move out of the storage box 33. The height of the lumbar support 3 exceeding the backplane increases. Thus, when the angle between the backrest and the seat plate 5 becomes smaller, the center of gravity of the user's upper body changes. By increasing the support amplitude of the lumbar support 3, the pressure on the user's lumbar spine is reduced to adapt to the user's sitting posture.
[0043] Synchronously, the rotation of the backrest 2 pulls the fifth rod 28 to move. The fifth rod 28 pulls the second rack 34 to move. The second gear 29 interacts with the second rack 34 to make the second gear 29 rotate. The second gear 29 rotates to drive the rotating plate 30 to rotate. The rotating plate 30 rotates into the first groove 40, so that the first seat cushion 8 and the second seat cushion 12 are basically on the same plane.
[0044] When the top end of the backrest 2 moves away from the seat board 5, that is, when the angle between the backrest 2 and the seat board 5 becomes larger, the backrest 2 rotates, causing the connecting end of the fourth rod 27 and the seat board 5 to rotate. The other end of the fourth rod 27 pulls the third rod 26 and the first rack 25 to move, and each component moves in the opposite direction to before. The lumbar support 3 moves into the storage box 33, and the height of the lumbar support 3 exceeding the backboard plane decreases. Thus, when the angle between the backboard and the seat board 5 becomes larger, the center of gravity of the user's upper body changes, and the pressure on the lumbar spine is dispersed to other parts of the upper body. The pressure on the lumbar spine is smaller, and the support range of the lumbar support 3 is reduced to increase the user's comfort and adapt to the user's sitting posture;
[0045] Synchronously, the rotation of the backrest 2 pushes the fifth rod 28 to move. The fifth rod 28 pushes the second rack 34 to move. The interaction between the second gear 29 and the second rack 34 causes the second gear 29 to rotate. The rotation of the second gear 29 drives the rotating plate 30 to rotate. One end of the rotating plate 30 moves away from the first groove 40, and the first seat cushion 8 of the rotating plate 30 tilts up. Thus, when the angle between the backboard and the seat board 5 becomes larger, the rotating plate 30 and the first seat cushion 8 support the bottom of the user's thighs to prevent the user from sliding down.
[0046] Through the above steps, the problem in the prior art that the lumbar support 3 cannot change the amplitude of supporting the human waist with the change of the body angle of a person and cannot be adaptively adjusted by the user according to their sitting posture is solved.
