Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Please see Figures 1-8 This utility model provides a technical solution: a massage chair support, including: a base support 1, a chair backrest 2, and a chair seat 3. The chair seat 3 is fixedly installed above the base support 1. The chair backrest 2 is hinged to the chair seat 3. An electric telescopic rod 4 is installed between the chair seat 3 and the chair backrest 2. A walking massage mechanism 5 is provided on the chair backrest 2 and the chair seat 3. The walking massage mechanism 5 walks on the chair seat 3 and the chair backrest 2 to massage the back and buttocks of the human body. Driven by the electric telescopic rod 4, the chair backrest 2 automatically swings relative to the chair seat 3 to adjust the posture of the human body, so that the walking massage mechanism 5 applies different forces to the back.

[0032] The chair frame backrest 2 includes two symmetrical backrest guide rails 22, and the backrest guide rails 22 are fixedly connected to the inner side of the backrest rack 21. The chair frame seat 3 includes two symmetrical seat frame guide rails 32, and the seat frame rack 33 is fixedly connected to the inner side of the seat frame guide rails 32.

[0033] Two pairs of seat support columns 11 and a pair of load-bearing support columns 12 are symmetrically installed on the base bracket 1. One pair of seat support columns 11 is fixedly connected to the seat frame guide rail 32, and the other pair is rotatably connected to one end of the double-headed connector 7. The upper end of the load-bearing support column 12 is provided with a limit pin 121, which is slidably connected to the double-headed connector 7.

[0034] A double-headed connector 7 is installed between the chair backrest 2 and the chair seat 3. The double-headed connector 7 includes a fixed outer shell 72 and an arc-shaped plate 71. The two ends of the fixed outer shell 72 are rotatably connected to a lower pad 76 and an upper pad 77 through anti-collision bolt assemblies 8. The lower pad 76 is fixedly installed to the seat guide rail 32, and the upper pad 77 is fixedly installed to the backrest guide rail 22. At the same time, a rotating hole 761 is opened at the lower end of the lower pad 76. The lower pad 76 is rotatably connected to the seat support column 11 by a pin passing through the rotating hole 761. Through the action of the upper pad 77 and the lower pad 76, the double-headed connector 7 can swing up and down relative to the chair seat 3. At the same time, the chair backrest 2 can also swing up and down relative to the double-headed connector 7, so as to realize the unfolding of the chair backrest 2 relative to the chair seat 3.

[0035] An arc-shaped plate 71 is fixedly installed on the outer side of the fixed housing 72. A limiting arc-shaped groove 73 is provided on the arc-shaped plate 71. The limiting arc-shaped groove 73 is slidably connected to the limiting pin 121. Through the cooperation of the limiting pin 121 and the limiting arc-shaped groove 73, the electric telescopic rod 4 can swing along the fixed track when driving the chair back 2 to swing.

[0036] An internal track 74 is fixedly installed inside the fixed outer shell 72. The two ends of the internal track 74 are respectively movably connected to the seat frame guide rail 32 and the backrest guide rail 22. The two ends of the internal track 74 are provided with a third semi-circular groove 741 and a fourth semi-circular groove 742. The backrest guide rail 22 is provided with a first docking semi-circular groove 221 at its end, and the seat frame guide rail 32 is provided with a second docking semi-circular groove 321 at its end. The first docking semi-circular groove 221 and the third semi-circular groove 741 are respectively formed to form a circular hole. The second docking semi-circular groove 321 and the fourth semi-circular groove 742 are respectively formed 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 connector 7 to swing up and down, the seat frame guide rail 32 and the backrest guide rail 22 will be tightly connected or separated from the two ends of the internal track 74. During the docking process, the anti-collision bolt assembly 8 limits the position and produces an anti-collision effect.

[0037] The built-in track 74 has symmetrical movable grooves 743 on its upper surface at both ends. A patching piece 75 is movably installed within the movable groove 743. The patching piece 75 is Z-shaped, and its upper ends are fixedly mounted on the upper pad 77 and lower pad 76, respectively. When the seat frame guide rail 32 and the backrest guide rail 22 are opened relative to each other, the backrest guide rail 22 and the built-in track 74 rotate relative to each other around the anti-collision bolt assembly 8. The upper contact points of the backrest guide rail 22 and the built-in track 74 separate, while the lower contact points are tightly joined. It should be noted that the joint ends of the backrest guide rail 22 and the seat frame guide rail 32 with the fixed outer shell 72 are not flush. This non-flushness creates gaps, causing gaps during the relative rotation of the backrest guide rail 22 and the seat frame guide rail 32 with the fixed outer shell 72. It has a certain amount of rotation space. Conversely, when the seat frame guide rail 32 and the backrest guide rail 22 are relatively reset, the lower contact point of the backrest guide rail 22 and the built-in track 74 separates, while the upper contact point is tightly connected. Similarly, the seat frame guide rail 32 and the built-in track 74 rotate relative to each other around the anti-collision bolt assembly 8 as the axis, and the contact points separate or are tightly connected. Because the anti-collision bolt assembly 8 is preset to a lower position, the gap caused by the separation of the upper contact point is large, which will affect the normal movement of the walking massage mechanism 5. The presence of the patch 75 can make up for the gap caused by the separation of the upper contact point, so that the walking massage mechanism 5 can move normally. The gap of the separation of the lower contact point is small and does not affect the movement of the walking massage mechanism 5, so the patch 75 is not needed.

[0038] The walking massage mechanism 5 includes a first walking wheel 51 and a second walking wheel 52, which are connected by a transmission belt 53. Both the first walking wheel 51 and the second walking wheel 52 are composed of gears and pulleys. The gears mesh with the backrest rack 21 or the seat frame rack 33, and the pulleys slide to connect the backrest guide rail 22, the built-in track 74, and the seat frame guide rail 32. It should be emphasized that the spacing between the first walking wheel 51 and the second walking wheel 52 is set such that at least one pair of walking wheels is on the backrest guide rail 22 or the seat frame guide rail 32, so that the walking massage mechanism 5 is always engaged with the rack. Therefore, when passing the built-in track 74, the walking massage mechanism 5 can move normally without being affected.

[0039] Working principle: The chair backrest 2 is rotatably connected to the double-headed connector 7, the double-headed connector 7 is rotatably connected to 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 backrest 2 to drive the chair backrest 2 to unfold and reset relative to the chair frame seat 3, thus assisting in the switching of human posture.

[0040] Meanwhile, a walking massage mechanism 5 is set 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 for the walking massage mechanism 5 to pass normally through the two separate tracks, an internal track 74 and a patch 75 are set in the double-headed connector 7, so that the walking massage mechanism 5 can still move stably without being affected during the movement of the track joint.

[0041] An arc-shaped plate 71 is provided on the side of the double-headed connector 7 to limit the sliding of the base bracket 1, thereby limiting the double-headed connector 7 and making the chair frame backrest 2 repeat the same trajectory during the swinging process.

[0042] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
