[0046] Example 1:

[0047] like Figure 1 The seat shown is a massage chair in this embodiment of the application, which includes a backrest (not shown in the figure), a seat 1, a buttock massage device and a base frame 3 for contacting the ground. The seat 1 and the buttock massage device are mounted on the base frame 3.

[0048] The chair seat 1 includes a U-shaped seat frame and a first flexible member (not shown in the figure) installed on the seat frame to support the human buttocks. The left and right sides of the seat frame are used to connect with the backrest. The first flexible member is located above the seat frame. The first flexible member located in the hollow part of the seat frame can support the human buttocks, thereby avoiding the buttock massage device directly bearing the weight of the human body.

[0049] It is worth noting that when the massage chair does not have a backrest, the shape of the seat frame can also be similar to a square; that is, a stool.

[0050] Generally, the first flexible component can be made of fabric, leather, sponge, or other flexible materials; preferably, it is a mesh fabric. The first flexible component is fixed to the seat frame by pressing and embedding or bonding. The specific installation structure between the first flexible component and the seat frame can be referred to the mesh fabric installation structure disclosed in CN110043536A, CN110063606A, CN208540955U, CN209694607U, and CN209769730U.

[0051] like Figure 3 As shown, the buttock massage device includes a base 20 installed below the seat frame, and a first drive motor 21, a main rotating shaft 26, two first massage components 22 on the left and right, two second massage components 23 on the left and right, two third massage components 24 on the left and right, and two fourth massage components 25 on the left and right, all installed on the base 20.

[0052] The first massage component 22 is sleeved and installed on the main rotating shaft 26, and the left and right first massage components 22 are respectively located on the outer sides of the left and right sides of the seat frame;

[0053] One end of the second massage component 23 is movably mounted on the base 20, and the other end is sleeved on the main rotating shaft 26; the two second massage components 23 are located on the inner sides of the left and right sides of the seat frame.

[0054] One end of the third massage component 24 is movably mounted on the base 20, and the other end is sleeved on the main rotating shaft 26; the two third massage components 24 are located on the inner sides of the left and right sides of the seat frame.

[0055] One end of the fourth massage component 25 is movably mounted on the base 20, and the other end is sleeved on the main rotating shaft 26; the two fourth massage components 25 are located on the inner sides of the left and right sides of the seat frame.

[0056] The first drive motor 21 drives the main shaft 26 to rotate, thereby causing the first massage component 22 to massage the left and right sides of the human buttocks, and simultaneously causing the second massage component 23 to massage the human hips, and simultaneously causing the third massage component 24 to massage the human thighs, and simultaneously causing the fourth massage component 25 to massage the human buttocks.

[0057] In this way, by using a first drive motor 21 to simultaneously drive four massage components, a high degree of integration of the buttock massage device is achieved, and the structure is rationally distributed.

The massage plate 220 is sleeved on the first eccentric bushing 221 through the first bearing 222. The first drive motor 21 drives the main rotating shaft 26 to rotate, which enables the airbag to move back and forth in the up and down direction and the front and back direction, thereby realizing the massage of both sides of the human buttocks.

[0059] In this way, by making the airbag move back and forth in the up-and-down and forward-and-backward directions, the airbag can rub and massage the side of the buttocks, thus improving the comfort of the massage.

[0060] In a further preferred embodiment, the first eccentric bushing 221 is provided with a first mounting hole 2210, the axis of the first mounting hole 2210 is parallel to the axis of the eccentric bushing but not on the same axis, and the first eccentric bushing 221 is fitted onto the main rotating shaft 26 through the first mounting hole 2210.

[0061] In this way, when the first drive motor 21 drives the main rotating shaft 26 to rotate, the airbag can make circular motion in the vertical plane, thereby realizing the kneading and massaging of the human buttocks.

[0062] In a further preferred embodiment, the first massage component 22 further includes a bearing mounting base 224, which is fixedly connected to the massage plate 220. The bearing mounting base 224 is sleeved on the first bearing 222 and abuts against the inner side of the first bearing 222. The inner side of the massage plate 220 abuts against the outer side of the first bearing 222. This arrangement fixes the first bearing 222, the massage plate 220, and the bearing mounting base 224 into a whole, ensuring the stability of the entire installation structure.

[0063] In a further preferred embodiment, the first eccentric bushing 221 is also provided with a flange, the flange being located at the inner end of the first eccentric bushing 221 and abutting against the inner surface of the first bearing 222;

[0064] The first massage component 22 also includes a baffle 223 that is loosely fitted on the main rotating shaft 26. The baffle 223 is fixedly connected to the outer side of the first eccentric bushing 221 and abuts against the outer side of the first bearing 222.

[0065] Further preferably, the massage plate 220 includes an integrally formed upper mounting plate 2201 and a lower mounting plate 2202, and a connecting plate 2203 for connecting the upper mounting plate 2201 and the lower mounting plate 2202.
