When the universal shaft 7 makes a reciprocating motion back and forth, the universal shaft 7 pushes the rollers of the sofa iron seat frame assembly 19 to make a reciprocating motion back and forth in the slide rails of the swing sofa support iron frame 16. Because the arc-shaped left slide rail 17 and the arc-shaped right slide rail 15 are arc-shaped, when the rollers 18 roll in the slide rails, the walking track makes an arc-shaped motion according to the arc path, realizing not only the reciprocating motion back and forth, but also the undulating motion like swinging on a swing, achieving the real free swing function. In this way, when the user sits on the multifunctional massage sofa, the sofa massage movement mechanism 29 at the back of the massage sofa can provide multiple functions such as knocking, kneading, percussion, up and down shaping and fixed-point massage. Coupled with the ability of the sofa to swing back and forth, it directly improves the multifunctionality of the multifunctional massage sofa.

[0036] On the outer side of the backrest 26, there is a fixed connection with a sofa human body curve track 28. The sofa human body curve track 28 can limit the up and down sliding of the sofa massage mechanism 29 to provide a full-range massage for the back of the user. On both sides of the backrest 26, there are fixed connections with quick-release buckles 27. The two quick-release buckles 27 can make the rear side of the front backrest 30 and the edge of the backrest 26 be spliced and fixed relatively. The front ends of the two quick-release buckles 27 are movably clamped with the front backrest 30. The front end of the front backrest 30 is fixedly connected with a sofa cushion 31. The sofa cushion 31 can be made of leather or cloth. The sofa cushion 31 is directly relied on by the human body when sitting or lying. Inside the sofa human body curve track 28, there is a sliding connection with a sofa massage mechanism 29. The sofa massage mechanism 29 belongs to relatively mature existing technology. Through the massage hammers and connecting rod structures on the sofa massage mechanism 29, it can provide multiple functions such as knocking, kneading, percussion, up and down shaping, and fixed-point massage for the human body. The front end of the sofa massage mechanism 29 is movably connected with the inner side of the sofa cushion 31.

[0037] On both sides of the sofa seat frame 22, there are fixed connections with multiple female snap fasteners 23. The outer sides of the multiple female snap fasteners 23 are movably clamped with multiple male snap fasteners 24. The multiple male snap fasteners 24 on both sides can be inserted into the grooves inside the female snap fasteners 23. In this way, the male snap fasteners 24 can be installed and fixed with the sofa seat frame 22. Similarly, the sofa left armrest 21 and the sofa right armrest 25 on the outer sides of the male snap fasteners 24 can be installed on both sides of the sofa seat frame 22. The outer sides of the multiple male snap fasteners 24 are fixedly connected with the sofa right armrest 25. On the other side of the outer sides of the multiple male snap fasteners 24, there is a fixed connection with the sofa left armrest 21. The rear side of the backrest 26 is movably clamped with the top end of the sofa seat frame 22. The sofa seat frame 22 is fixedly connected above multiple sofa quick-release inserts 20. The sofa seat frame 22 can be inserted and docked with the lower sofa iron seat frame assembly 19 through the sofa quick-release inserts 20. The bottom end of the sofa seat frame 22 is fixedly connected with the top end of the sofa iron seat frame assembly 19.

[0038] Working principle:

[0039] When using the multifunctional massage sofa, the user first relies on the sofa cushion. The sofa human body curve track behind the sofa cushion can conform to the human body arc and structure. Through the front and back swinging of the multifunctional massage sofa and the rear sofa massage mechanism, it can achieve the multifunctional massage and relaxation effect:

[0040] The multi-stage deceleration drive working process of the multifunctional massage sofa:

[0041] The aluminum small pulley 2 and the aluminum large pulley 4 both belong to toothed belt pulleys, and the synchronous belt 3 belongs to a toothed belt. In this way, the synchronous belt 3 can perform meshing transmission on the outer sides of the aluminum small pulley 2 and the aluminum large pulley 4. After connecting the power supply to start the motor 1, the motor 1 can drive the aluminum small pulley 2 to rotate through the output shaft. The aluminum small pulley 2 rotates synchronously with the aluminum large pulley 4 through the synchronous belt 3 for the first deceleration. Then, the aluminum large pulley 4 rotates to drive the metal worm 12 to rotate. The metal worm 12 meshes with the helical gear 10 to change the transmission direction and perform the second deceleration. The helical gear 10 is connected to the crank 5 through the crankshaft 11 and is assembled and fixed in position through the speed reducer 13 to form a speed reduction mechanism;

[0042] Movement process of the swing drive connection structure of the multifunctional massage sofa:

[0043] The end of the universal shaft 7 and the upper universal shaft ball head fixing seat 8 are connected to the lower universal shaft ball head fixing seat 9 through an end face ball head, enabling multi-directional free swing. The upper universal shaft ball head fixing seat 8 and the lower universal shaft ball head fixing seat 9 are fixed on the front cross beam of the sofa iron seat frame assembly 19 by screws. When the motor 1 drives the crank 5 to rotate, the crank 5 will drive the universal shaft 7 to perform reciprocating forward and backward movements. The crank 5 is connected to the swing arm 6 through a bearing, enabling the transmission freedom of the swing arm 6. The speed reducer 13 is fixed on the swing fixing seat 14 by screws;

[0044] Movement process of the swing mechanism of the multifunctional massage sofa:

[0045] The arc-shaped left slide rail 17 and the arc-shaped right slide rail 15 are welded on the swing sofa support iron frame 16. There are 4 rollers 18 on both sides of the sofa iron seat frame assembly 19, which are fixed on the sofa iron seat frame assembly 19 through iron shafts. The 4 rollers of the sofa iron seat frame assembly 19 are installed in the arc-shaped left slide rail 17 and the arc-shaped right slide rail 15 on the swing sofa support iron frame 16. The rollers 18 can freely roll in the arc-shaped left slide rail 17 and the arc-shaped right slide rail 15 according to the slide rail path. When the universal shaft 7 performs reciprocating forward and backward movements, the universal shaft 7 pushes the rollers of the sofa iron seat frame assembly 19 to perform reciprocating back and forth movements in the slide rails of the swing sofa support iron frame 16. Since the arc-shaped left slide rail 17 and the arc-shaped right slide rail 15 are arc-shaped, when the rollers 18 roll in the slide rails, the walking trajectory makes an arc-shaped movement according to the arc path, realizing not only the reciprocating back and forth movement but also the undulating movement like swinging on a swing, achieving a true free swing function. Using the motor 1, after multiple decelerations, it can drive the sofa swing mechanism to perform forward and backward swing movements on the swing sofa support iron frame 16;

[0046] Backrest splicing and assembly structure of the multifunctional massage sofa:

[0047] The sofa body curve track 28 can limit the up and down sliding of the sofa massage mechanism 29 to provide a full-range massage for the back of the user. The two quick-release buckles 27 can enable the rear side of the front backrest 30 to be spliced and fixedly installed relative to the edge of the backrest 26. The sofa upholstery 31 can be made of leather or cloth. The sofa upholstery 31 is directly relied on by the human body for sitting and lying. The sofa massage mechanism 29 is slidably connected to the inner side of the sofa body curve track 28. The sofa massage mechanism 29 belongs to a relatively mature existing technology. Through the massage hammer and connecting rod structure on the sofa massage mechanism 29, it can provide multiple functions such as knocking, kneading, percussion, up and down shaping, and fixed-point massage for the human body.
