[0031] Please refer to Figures 1 to 5 The embodiment of the present application provides a massage chair 100, including a massage mechanism 20 and a massage chair frame 10, wherein the massage mechanism 20 is arranged on a segmented guide rail structure of the massage chair frame 10, and the massage mechanism 20 can reciprocate on the moving guide rail of the segmented guide rail structure. The massage chair frame 10 includes a base 11, a backrest frame 12 and a seat frame 13 arranged on the base 11, and a segmented guide rail structure, wherein a backrest guide rail 121 of the segmented guide rail structure is arranged on the backrest frame 12, and a seat guide rail 131 of the segmented guide rail structure is arranged on the seat frame 13.

[0032] Specifically, Figure 3 As shown, the segmented rail structure includes a backrest rail 121 and a seat rail 131, and one end of the backrest rail 121 close to the seat rail 131 is connected to the other end of the seat rail 131 close to the backrest rail 121 through a hinge assembly 14, so that the backrest rail 121 and the seat rail 131 together form a movable rail for the reciprocating motion of the massage mechanism 20 of the massage chair 100; wherein the backrest rail 121 is a curved rail, and the seat rail 131 is a straight rail, the curved rail and the straight rail are tangent to each other, and the hinge point of the hinge assembly 14 coincides or approximately coincides with the tangent point of the curved rail and the straight rail. The segmented rail structure can solve the problem in the prior art that the massage mechanism 20 cannot smoothly reciprocate on the backrest rail 121 and the seat rail 131, resulting in the massage chair 100 being unable to adjust the back and seat angles and perform continuous and complete massage.

[0033] It should be noted that the segmented guide rail structure includes a backrest guide rail 121 and a seat guide rail 131. During the actual installation process, a hinge assembly 14 is provided at one end of the backrest guide rail 121 close to the seat guide rail 131 and at another end of the seat guide rail 131 close to the backrest guide 121, so that the backrest guide rail 121 and the seat guide rail 131 are connected through the hinge assembly 14, so that the backrest guide rail 121 and the seat guide rail 131 can jointly form a movable guide rail, thereby enabling the massage mechanism 20 to realize continuous reciprocating motion on the movable guide rail, and, under the action of the hinge assembly 14, the movable guide rail can rotate at the connection between the backrest guide rail 121 and the seat guide rail 131, so that the angle between the backrest guide rail 121 and the seat guide 131 can be adjusted, thereby enabling the movable guide rail to meet the massage requirements under different massage postures. For example, the angle between the backrest rail 121 and the seat rail 131 may be 90°, 110°, 135°, 150°, 180°, etc., to respectively correspond to sitting massage, lying massage, etc.

[0034] On this basis, the backrest rail 121 is a curved rail, in other words, the shape of the curved rail is a curve, and the seat rail 131 is a straight rail, in other words, the shape of the straight rail is a straight line. In order to make the transition of the connection between the backrest rail 121 and the seat rail 131 smoother, the curved rail and the straight rail are tangent, that is, the curve and the straight line are tangent, and the hinge point of the hinge assembly 14 coincides or approximately coincides with the tangent point of the curved rail and the straight rail, so that the massage mechanism 20 can pass smoothly when moving along the moving rail to the connection between the backrest rail 121 and the seat rail 131 without shaking or abnormal sound. Regarding the actual shape of the curved rail, those skilled in the art should be able to select and design it according to actual conditions. For example, the curved rail can be formed by connecting multiple sections of curves with different curvatures to adapt to the curves of the head, neck, and back of the human body respectively. At this time, the curved rail and the straight rail are tangent, which means that the part of the curved rail close to the straight rail is tangent to the straight line of the straight rail.

[0035] Compared with the prior art, the segmented guide rail structure provided in the present application is characterized in that a hinge assembly 14 is provided at one end of the backrest guide rail 121 close to the seat guide rail 131 and at another end of the seat guide rail 131 close to the backrest guide 121, so that the backrest guide rail 121 and the seat guide rail 131 are connected together by the hinge assembly 14 to form a movable guide rail for reciprocating motion of the massage mechanism 20, so that the massage mechanism 20 can perform continuous massage on the back and the seat, and, under the action of the hinge assembly 14, the movable guide rail can rotate at the connection between the backrest guide rail 121 and the seat guide 131, so that the angle between the backrest guide rail 121 and the seat guide 131 can be adjusted, thereby enabling the massage mechanism 20 to meet the massage needs under different massage postures. On this basis, the curved guide rail and the straight guide rail are tangent, and the hinge point of the hinge assembly 14 coincides or approximately coincides with the tangent point of the curved guide rail and the straight guide rail, so that the transition of the formed movable guide rail at the connection between the back guide rail 121 and the seat guide rail 131 is smoother, so that the massage mechanism 20 can pass smoothly when moving along the movable guide rail to the connection between the back guide rail 121 and the seat guide 131 without shaking or abnormal noise.

[0036] Alternatively, if Figure 4 and Figure 5 As shown, the backrest guide rail 121 and the seat guide rail 131 are both U-shaped structures, and the U-shaped structure includes two folding arms parallel to each other and a connecting arm connecting the two folding arms. The roller 21 of the massage mechanism 20 can be movably accommodated in the semi-enclosed accommodation space formed by the U-shaped structure. The edge of the folding arm of the backrest guide rail 121 located on the side of the base 11 of the massage chair frame 10 of the massage chair 100 is also provided with a rack 1211, and the rack 1211 is meshed with the running gear 22 of the massage mechanism 20, so that when the roller 21 of the massage mechanism 20 rolls to the accommodation space formed by the U-shaped structure of the backrest guide rail 121, the massage mechanism 20 The traveling gear 22 can drive the massage mechanism 20 to climb to the highest point of the backrest guide 121 by cooperating with the rack 1211, and there is a gap between the surface of the folding arm of the seat guide 131 located on the side close to the base 11 and the surface of the traveling gear 22, so that when the roller 21 of the massage mechanism 20 rolls into the accommodating space formed by the U-shaped structure of the seat guide 131, the traveling gear 22 of the massage mechanism 20 will not contact the surface of the folding arm of the seat guide 131 located on the side close to the base 11, thereby avoiding shaking when the traveling gear 22 moves to the connection between the backrest guide 121 and the seat guide 131.

[0037] Generally, the massage mechanism 20 includes at least two roller assemblies, each roller assembly includes two rollers 21 and a connecting rod connecting the two rollers 21. Figure 4As shown, here, the massage mechanism 20 includes two groups of roller assemblies as an example for explanation. When the roller 21 of the massage mechanism 20 is movably accommodated in the segmented guide rail structure, the two groups of roller assemblies are arranged front to back along the direction from the backrest guide rail 121 to the seat guide rail 131, and the two rollers of each group of roller assemblies are arranged left to right. In accordance with the above-mentioned rack set on the backrest guide rail 121, the traveling gear should be arranged on the connecting rod of the roller assembly located at the front end (i.e., on the side close to the backrest guide rail 121) to ensure that the traveling gear can travel along the rack on the backrest guide rail 121, thereby driving the massage mechanism 20 to climb along the backrest guide rail 121.

[0038] Alternatively, if Figure 3 and Figure 4 As shown, the hinge assembly 14 includes a first connecting member and a second connecting member, the first connecting member is connected to the backrest guide 121 and is located at one end of the backrest guide 121 close to the seat guide 131, the second connecting member is connected to the seat guide 131 and is located at one end of the seat guide 131 close to the backrest guide 121, the first connecting member and the second connecting member are hinged so that the backrest guide 121 and the seat guide 131 can be rotatably connected, so that the angle between the backrest guide 121 and the seat guide 131 can be adjusted.

[0039] Alternatively, if Figure 3 and Figure 4 As shown, the hinge assembly 14 also includes a hinge shaft, a first hinge hole is provided on the first connecting member, a second hinge hole is provided on the second connecting member corresponding to the first hinge hole, the hinge shaft is passed through the first hinge hole and the second hinge hole, and the hinge point of the hinge assembly 14 is the axis of the hinge shaft. Therefore, the axis of the hinge shaft is located at the intersection point of the curved guide rail and the straight guide rail, which coincides or approximately coincides with each other, so that the transition of the formed movable guide rail at the connection between the backrest guide rail 121 and the seat guide rail 131 is smoother.

[0040] Alternatively, if Figures 1 to 3 As shown, the number of backrest rails 121 and seat rails 131 are both two, and the two backrest rails 121 and the two seat rails 131 correspond to each other to form two movable rails respectively, and the two movable rails are respectively arranged on the left and right sides of the massage chair frame 10 of the massage chair 100, so that the massage mechanism 20 can stably and reliably reciprocate along the movable rails relative to the massage chair frame 10, thereby massaging the user's back and seat.

[0041] Alternatively, if Figure 1As shown, a driving mechanism 111 is provided on the base 11, and the driving mechanism 111 is connected to the seat frame 13. The driving mechanism 111 is used to drive the seat frame 13 to move back and forth relative to the base 11. Thus, the driving mechanism 111 can drive the seat frame 13 to move back and forth relative to the base 11 and the backrest frame 12 to lie flat or rise relative to the seat frame 13, so that the massage chair 100 can meet the massage needs under different massage postures. For example, a mounting rod is connected between the left and right sides of the seat frame 13, and a mounting seat is provided on the mounting rod. The driving end of the driving mechanism 111 is hinged on the mounting seat. Among them, the driving mechanism 111 is an electric cylinder or an electric push rod.
