[0031] It should be noted that if Figures 1 to 4 As shown, the massage chair frame includes a backrest frame 100, a seat frame 101, a lower seat frame 102 and a driving member 109, wherein the backrest frame 100 and the seat frame 101 are hinged by a hinge assembly so that the angle between the backrest frame 100 and the seat frame 101 can be flexibly adjusted, a rolling member 105 is provided on the backrest frame 100, and a slide groove 107 is provided on the lower seat frame 102, and the rolling member 105 is slidably provided in the slide groove 107 to support the backrest frame 100 through the movement coordination of the rolling member 105 and the slide groove 107, thereby improving the stability of the movable connection between the backrest frame 100 and the seat frame 101.

[0032] In addition, the seat frame 101 and the lower seat frame 102 are hingedly connected via a first link 104 and a second link 103 to form a four-bar linkage. In other words, the opposite ends of the first link 104 are hinged to the seat frame 101 and the lower seat frame 102 respectively via hinge shafts 108, and the opposite ends of the second link 103 are hinged to the seat frame 101 and the lower seat frame 102 respectively via hinge shafts 108. Furthermore, the seat frame 101, the lower seat frame 102, the first link 104, and the second link 103 together form a four-bar linkage. On this basis, a driving member 109 is in transmission connection with the seat frame 101, so that under the driving action of the driving member 109, the seat frame 101 is driven to move relative to the lower seat frame 102.

[0033] In actual use, please follow Figures 1 to 2 When the driving member 109 drives the seat frame 101 to swing toward the front of the massage chair, it can simultaneously drive the backrest frame 100 to lie flat, so that the backrest frame 100 gradually changes from a sitting state to a lying state; please follow the Figure 2 to Figure 1 The order of the driving member 109 is understood, when the driving member 109 drives the seat frame 101 to swing toward the rear of the massage chair, it can simultaneously drive the backrest frame 100 to rise, so that the backrest frame 100 is gradually transformed from a lying state to a sitting state.

[0034] Compared with the existing technology, the massage chair frame provided in the present application adopts a segmented chair frame structure (i.e., a backrest frame 100 and a seat frame 101), which not only can realize the lying down and raising movements of the backrest frame 100, but also can make the angle between the backrest frame 100 and the seat frame 101 flexibly adjustable. For example, the angle between the plane where the backrest frame 100 is located and the plane where the seat frame 101 is located is 90°~180°. Users can adjust it according to their own needs, thereby ensuring that the massage movement can move back and forth between the backrest frame 100 and the seat frame 101 to perform massage.

[0035] In addition, the massage chair frame provided in the present application adds a rolling member 105 to the backrest frame 100 and a slide groove 107 to the lower seat frame 102, and makes the rolling member 105 always slide along the inner wall of the slide groove 107 to provide reliable, stable and continuous support for the backrest frame 100, thereby improving the stability of the movable connection between the backrest frame 100 and the seat frame 101, solving the problem of unstable sitting and lying adjustment caused by the movable connection between the backrest frame 100 and the seat frame 101 in the prior art, and also simplifying the structure of the massage chair frame in conjunction with the four-bar linkage.

[0036] As an implementable method, Figure 1As shown, an opening (not shown in the figure) is provided at one end of the slide groove 107 close to the backrest frame 100 so that the rolling element 105 can be slidably disposed in the slide groove 107 through the opening during assembly.

When the massage chair is in a reclining state, the support member 106 can also be slidably disposed in the slide groove 107 through the opening. At this time, the rolling member 105 has moved along the slide groove 107 to the end of the slide groove 107 close to the seat frame 101. Therefore, the support member 106 and the rolling member 105 cooperate to support the backrest frame. The support member 106 further improves the stability of the connection between the backrest frame and the seat frame 101 when the backrest frame is in the reclining state. For example, the support member 106 and the rolling member 105 can both be rollers.

[0038] As an implementable method, Figure 1 、 Figure 2 and Figure 4 As shown, the lower seat frame 102 is provided with a first support and a second support in a sequentially spaced relationship along the front-to-back direction of the massage chair. Opposite ends of a slide 107 are fixedly mounted on the first support and the second support, respectively.

The two rolling members 105 and the two sliding grooves 107 are arranged in a one-to-one correspondence to improve the stability of the backrest frame 100 in the left-right direction of the massage chair.

[0041] As an implementable method, Figure 1and Figure 2 As shown, the number of the first link 104, the second link 103 and the four-link mechanism are all two, the two first links 104 are symmetrically arranged on the opposite sides of the lower seat frame 102 along the left-right direction of the massage chair, and the two second links 103 are symmetrically arranged on the opposite sides of the lower seat frame 102 along the left-right direction of the massage chair, thereby improving the stability of the seat frame 101 in the left-right direction of the massage chair when it moves relative to the left.

[0042] As an implementable method, Figures 1 to 3 As shown, the massage chair frame also includes a motion guide rail, a transmission rack and a massage movement (not shown in the figure). The motion guide rail is laid from the backrest frame 100 to the seat frame 101. The massage movement is set on the motion guide rail through the movement of the transmission rack and can massage the user.

[0043] As an implementable method, Figures 1 to 3 As shown, the motion guide rail includes a first guide rail fixedly mounted on the backrest frame 100 and a second guide rail fixedly mounted on the seat frame 101. The transmission rack includes a first rack fixedly mounted on the first guide rail and a second rack fixedly mounted on the second guide rail. The segmented guide rail structure design can be matched with the segmented chair frame structure design.

[0044] As an implementable method, Figures 1 to 3 As shown, the first guide rail is a curved guide rail, the second guide rail is a straight guide rail, the first rack is a curved rack, the second rack is a straight rack, and the hinge point of the hinge assembly is located on the dividing line of the curved rack and the straight rack. In this way, the smoothness of the movement of the massage movement when passing through the hinge point can be ensured, thereby avoiding abnormal phenomena such as shaking of the massage movement when passing through the hinge point.

[0045] The present application also provides a massage chair, comprising the above-mentioned massage chair frame. Since the structure and beneficial effects of the massage chair frame have been described in detail in the above-mentioned embodiments, they will not be repeated here.
