DETAILED DESCRIPTION

[0038] Example 1

[0039] Combine the following Figure 1-Figure 4 This embodiment is described in detail.

[0041] The swing rod 50 is provided on both sides of the back frame 30, one end of the swing rod 50 is hinged to the base 10, and the other end of the swing rod 50 is hinged to the hinge between the back frame 30 and the seat 40, that is, the swing rod 50 and the seat 40 are hinged to the same rotating shaft;

[0042] A linkage device is provided on both sides of the back frame 30, the linkage device includes one or more connecting rods, one end of the linkage device is hinged to the base 10, and the other end of the linkage device is hinged to the seat 40; and

[0043] A first telescopic device 1001, two ends of which are connected to the base 10, the back frame 30 and two of the swing rods 50;

[0044] When the first telescopic device 1001 is extended or contracted, the guide wheel 302 is pushed to slide on the guide rail 20, so that the angle between the swing rod 50 and the back frame 30 changes, and at the same time, the other end of the linkage device pulls the seat 40, so that the angle between the seat 40 and the back frame 30 changes. Specifically, when the first telescopic device 1001 is extended or contracted, the swing rod 50 is driven to rotate clockwise, thereby pushing the back frame 30 to move forward, and the guide wheel 302 is continuously raised along the guide rail 20, so that the back frame 30 moves forward and rotates counterclockwise to tilt backward, thereby reducing the rear end space occupied by the back frame 30 when it tilts backward, and realizing the wall-mounted arrangement of the massage chair.

[0045] In this embodiment, the guide rail 20 gradually rises while extending forward to assist the rotation of the back frame 30. The "forward" direction is the direction that the user faces when sitting on the seat 40 in normal use.

[0046] In this embodiment, the linkage device adopts a multi-link solution, including a first link 601, a second link 602 and a third link 603. One end of the first link 601 is hinged to the base 10, two ends of the second link 602 are respectively hinged to the other end of the first link 601 and the back frame 30, and two ends of the third link 603 are respectively hinged to the middle of the second link 602 and the middle of the seat 40. Further, one end of the second link 602 is hinged to the rotating shaft of the guide wheel 302, and the second link 602 moves with the guide wheel 302 and drives the third link 603 to drive the seat 40 to rotate.

[0047] In this embodiment, one end of the first telescopic device 1001 is hinged to the back frame 30, and the other end of the first telescopic device 1001 is hinged to the swing rod 50. Specifically, the fixed end of the first telescopic device 1001 is hinged to the swing rod 50, and the output end of the first telescopic device 1001 is hinged to the back frame 30. When the first telescopic device 1001 is in the contracted state, the back frame 30 is in the upright state, that is, the initial state, as shown in FIG. Figure 1 When the first telescopic device 1001 is in the extended state, the back frame 30 is in a zero gravity state, as shown in FIG. Figure 2 shown.

[0048] In this embodiment, Figure 4 As shown, a connecting rod 501 is provided between the two rocker arms 50, a connecting seat 301 is provided at the bottom of the back frame 30, guide wheels 302 are provided on both sides of the connecting seat 301, and the fixed end of the first telescopic device 1001 is hinged to the connecting rod 501, and the other end of the first telescopic device 1001 is hinged to the connecting seat 301.

[0049] A massage chair is also proposed in this embodiment, including the variable-angle massage chair frame mentioned above, and also including a calf portion 80, the top end of the calf portion 80 is hinged to the other end of the seat portion 40, so that the calf portion 80 rises and falls with the back frame 30; it also includes a second telescopic device 1002, one end of the second telescopic device 1002 is hinged to the back frame 30, specifically, the other end of the second telescopic device 1002 is hinged to the connecting seat 301, and the other end of the second telescopic device 1002 pushes on the calf portion 80, and the calf portion 80 is rotated by pushing the second telescopic device 1002.

[0050] In this embodiment, a calf push rod 90 is further included, one end of which is hinged to the front end of the back frame 30 and the other end is movably connected to the calf part 80. The output end of the second telescopic device 1002 is hinged to the middle of the calf push rod 90, and the fixed end of the second telescopic device 1002 is hinged to the connecting seat 301. Furthermore, a roller 901 is provided at one end of the calf push rod 90 that is connected to the calf part 80.

[0051] The massage chair proposed in this embodiment has the following working principle:

[0052] The initial state of the chair frame, that is, the upright state, is as follows Figure 1 As shown. The output end of the first telescopic device 1001 extends out, pushing the back frame 30 to rotate counterclockwise. At this time, the swing rod 50 rotates clockwise, pushing the back frame 30 to move forward, and the guide wheel 302 rolls forward along the guide rail 20. The guide wheel 302 continues to rise with the guide rail 20, thereby achieving the back frame 30 to tilt and move forward at the same time. In this process, the first connecting rod 601 rotates clockwise around the hinge point on the base 10, and the guide wheel 302 drives the second connecting rod 602 to rotate counterclockwise. The second connecting rod 602 drives the seat 40 to rotate counterclockwise relative to the back frame 30 through the third connecting rod 603, thereby achieving a change in the angle between the seat 40 and the back frame 30. At the same time, the output end of the second telescopic device 1002 extends out, pushing the calf push rod 90 to rotate around the hinge point with the back frame 30. The calf push rod 90 then pushes the calf 80 to the highest point, so that the chair frame switches to a zero gravity state, as shown in FIG. Figure 2 The first telescopic device 1001 and the second telescopic device 1002 are retracted, and the back frame 30, the seat 40 and the calf 80 return to their initial state.

[0053] Example 2

[0054] Combine the following Figure 5-Figure 8 This embodiment is described in detail.

[0055] The difference between this embodiment and embodiment 1 is that the linkage device in this embodiment adopts a single connecting rod body 701, one end of the connecting rod body 701 is hinged to the base 10, and the other end of the connecting rod body 701 is hinged to the seat 40. When the first telescopic device 1001 is in a retracted state, the back frame 30 is in an upright state, that is, an initial state, and when the first telescopic device 1001 is in an extended state, the back frame 30 is in a zero gravity state. The specific working principle is as follows:

[0056] The initial state of the chair frame, that is, the upright state, is as follows Figure 5 As shown. The output end of the first telescopic device 1001 extends out, pushing the back frame 30 to rotate counterclockwise, and at this time the swing rod 50 rotates clockwise, pushing the back frame 30 to move forward, and the guide wheel 302 rolls forward along the guide rail 20, so that the back frame 30 can tilt forward and backward and move forward at the same time. In this process, the connecting rod body 701 rotates clockwise around the connection point on the base 10 and pushes the seat 40 to rotate counterclockwise relative to the back frame 30, so as to achieve the change of the angle between the seat 40 and the back frame 30. The angle change of the calf part 80 is the same as that of Example 1, and will not be repeated here.

[0057] Example 3

[0058] This embodiment also adopts a single connecting rod solution. Figure 9-10 As shown, the difference from Example 2 is that one end of the first telescopic device 1001 is pivoted to the base 10, and the other end of the first telescopic device 1001 is pivoted to the back frame 30. Specifically, the fixed end of the first telescopic device 1001 is pivoted to the base 10, and the output end of the first telescopic device 1001 is pivoted to the back frame 30. When the first telescopic device 1001 is in a retracted state, the chair frame is in an initial state, and when the first telescopic device 1001 is in an extended state, the chair frame is in a zero gravity state. The specific switching process is the same as that of Example 2 and will not be repeated.

[0059] Example 4

[0060] Combine the following Figure 11-Figure 12 This embodiment is described in detail.

[0061] This embodiment also adopts a single-link solution, and the difference from Embodiment 2 is that the fixed end of the first telescopic device 1001 is hinged to the swing rod 50, and the output end of the first telescopic device 1001 is hinged to the base 10. When the first telescopic device 1001 is in the extended state, the chair frame is in the initial state, and when the first telescopic device 1001 is in the retracted state, the chair frame is in the zero gravity state. The specific switching process is the same as that of Embodiment 2 and will not be repeated.

[0062] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
