[0017] The chair frame backrest 2 comprises two symmetrical backrest guide rails 22, the inner sides of which are fixedly connected to the backrest rack 21, and the chair frame seat 3 comprises two symmetrical seat frame guide rails 32, the inner sides of which are fixedly connected to the seat frame rack 33; Two pairs of seat support pillars 11 and a pair of supporting pillars 12 are symmetrically installed on the base bracket 1, wherein one pair of seat support pillars 11 are fixedly connected to the seat frame guide rail 32, and the other pair is rotatably connected to one end of the double-headed connecting piece 7. A limiting pin rod 121 is provided on the upper end of the supporting pillar 12, and the limiting pin rod 121 is connected to the double-headed connecting piece 7 in a limiting sliding manner.

[0018] A double-headed connector 7 is installed between the chair frame backrest 2 and the chair frame seat 3. The double-headed connector 7 includes a fixed shell 72 and an arc-shaped plate 71. The two ends of the fixed shell 72 are rotatably connected to a lower gasket 76 and an upper gasket 77 through an anti-collision bolt assembly 8. The lower gasket 76 is fixedly installed on the seat frame guide rail 32, and the upper gasket 77 is fixedly installed on the backrest guide rail 22. At the same time, a rotating hole 761 is provided at the lower end of the lower gasket 76. A pin is passed through the rotating hole 761 to rotatably connect the lower gasket 76 to the seat plate pillar 11. Through the action of the upper gasket 77 and the lower gasket 76, the double-headed connector 7 can swing up and down relative to the chair frame seat 3, and at the same time, the chair frame backrest 2 can swing up and down relative to the double-headed connector 7, so that the chair frame backrest 2 can be unfolded relative to the chair frame seat 3.

[0019] An arc plate 71 is fixedly installed on the outer side of the fixed shell 72, and a limiting arc groove 73 is provided on the arc plate 71. The limiting arc groove 73 is slidably connected to the limiting pin rod 121. Through the cooperation of the limiting pin rod 121 and the limiting arc groove 73, the electric telescopic rod 4 can swing along the fixed track when driving the chair frame backrest 2 to swing.

[0020] A built-in track 74 is fixedly installed on the inner side of the fixed shell 72, and the two ends of the built-in track 74 are movably docked with the seat frame guide rail 32 and the backrest guide rail 22 respectively. A third semicircular groove 741 and a fourth semicircular groove 742 are opened on the sides of the two ends of the built-in track 74, a first docking semicircular groove 221 is opened at the end of the backrest guide rail 22, and a second docking semicircular groove 321 is opened at the end of the seat frame guide rail 32. The first docking semicircular groove 221 and the third semicircular groove 741 correspond to form a circular hole, and the second docking semicircular groove 321 and the fourth semicircular groove 742 correspond to form a circular hole. Two anti-collision bolt assemblies 8 pass through the above-mentioned circular holes. When the chair frame backrest 2 swings up and down and drives the double-headed connecting piece 7 to swing up and down, the seat frame guide rail 32 and the backrest guide rail 22 will be tightly docked or separated with the two ends of the built-in track 74. During the docking process, the anti-collision bolt assembly 8 is used to limit and produce an anti-collision effect.

[0021] The upper surfaces of the two ends of the built-in rail 74 are symmetrically provided with movable grooves 743, and the movable grooves 743 are movably provided with patching members 75, which are Z-shaped, and the upper ends of the two patching members 75 are fixedly mounted on the upper gasket 77 and the lower gasket 76 respectively. When the seat frame guide rail 32 and the backrest guide rail 22 are relatively opened, the backrest guide rail 22 and the built-in rail 74 rotate relative to each other with the anti-collision bolt assembly 8 as the axis, and the upper contact points of the backrest guide rail 22 and the built-in rail 74 are separated, and the lower contact points are closely connected. It should be supplemented that the butt ends of the backrest guide rail 22 and the seat frame guide rail 32 and the fixed shell 72 are not flat, and the non-flat ends will produce gaps, so that when the backrest guide rail 22 and the seat frame guide rail 32 are relatively rotated with the fixed shell 72, It has a certain rotation space. On the contrary, when the seat frame guide rail 32 and the backrest guide rail 22 are relatively reset, the lower contact points of the backrest guide rail 22 and the built-in track 74 are separated, and the upper contact points are tightly docked. Similarly, the seat frame guide rail 32 and the built-in track 74 rotate relative to each other with the anti-collision bolt assembly 8 as the axis, and the contact points are separated or tightly docked. Since the preset position of the anti-collision bolt assembly 8 is biased downward, the gap caused by the separation of the upper contact point is large, which will affect the normal walking of the walking massage movement 5. The existence of the patch 75 can make up for the gap caused by the separation of the upper contact point, so that the walking massage movement 5 can walk normally. The gap caused by the separation of the lower contact point is small, which does not affect the walking of the walking massage movement 5, so there is no need for a patch 75.

[0022] The walking massage movement 5 includes a first walking wheel 51 and a second walking wheel 52, which are connected by a transmission belt 53. The first walking wheel 51 and the second walking wheel 52 are both composed of stacked gears and pulleys. The gears are engaged with the backrest rack 21 or the seat frame rack 33, and the pulleys are slidably connected to the backrest guide 22, the built-in track 74 and the seat frame guide 32. It should be emphasized that the spacing between the first walking wheel 51 and the second walking wheel 52 is set to ensure that at least one pair of the walking wheels is on the backrest guide 22 or the seat frame guide 32, so that the walking massage movement 5 is always coordinated with the rack, and then when passing through the built-in track 74, the walking massage movement 5 can walk normally without being affected.

[0023] Working principle: The chair frame backrest 2 is rotated to connect the double-head connector 7, the double-head connector 7 is rotated to connect the chair frame seat 3, the chair frame seat 3 is fixedly installed on the base bracket 1, and an electric telescopic rod 4 is set between the chair frame seat 3 and the chair frame backrest 2 to drive the chair frame backrest 2 to expand and reset relative to the chair frame seat 3, and assist the switching of the human body posture; At the same time, a walking massage movement 5 is arranged between the chair frame seat 3 and the chair frame backrest 2, so that it can massage the back, waist and buttocks of the human body. In order to allow the walking massage movement 5 to pass through the two separated tracks normally, a built-in track 74 and a patching member 75 are arranged in the double-headed connector 7, so that the walking massage movement 5 can still move stably without being affected during the movement of the track docking. An arc plate 71 is provided on the side of the double-headed connecting member 7 to slide with the base bracket 1 to limit the position of the double-headed connecting member 7 so that the chair frame backrest 2 repeats the same trajectory during the swinging process.
