[0002] Massage chairs basically have the functions of moving forward and backward, and changing sitting and lying positions. In terms of massage functions, there are two types: walking massage movement and fixed massage movement. The former only needs one massage movement, which moves on an L-shaped track to complete reciprocating massage from the neck, back to the buttocks. The latter requires fixed massage movements distributed on the back and buttocks, which belongs to fixed-point massage. Operators can only design and distribute massage movements at the height of the regular human body, which is difficult to be compatible with all people and has poor comfort.

[0003] The massage chair is based on an iron frame, with various massage mechanisms installed, the edges are filled with soft padding, and the outside is covered with foreskin to form a complete and workable whole. The simple massage chair frame generally includes: a backrest frame, a seat frame, a base frame and an electric push rod, as well as a leg-beautifying frame hinged at the front end of the seat frame; driven by the electric push rod, the backrest frame and the seat frame can move forward and backward relative to the base frame, and complete the continuous change between sitting and lying positions.

[0033] Reference Figures 1 to 5 The massage chair frame includes a backrest frame 1, a seat cushion frame 2, a base frame 3, a leg beauty frame 4, an electric push rod 5 and a massage movement 6; the leg beauty frame 4 is hinged at the front end of the seat cushion frame 2, the seat cushion frame 2 is arranged above the base frame 3, and under the drive of the electric push rod 5, the backrest frame 1 and the seat cushion frame 2 can move forward and backward relative to the base frame 3, and complete the continuous change between the sitting position and the lying position, and the massage movement 6 is arranged on the backrest frame 1 and the seat cushion frame 2 to meet the massage of the backrest and buttocks, which is also the basic structure of the existing fixed massage movement.

[0034] A sliding frame 7 is arranged on the backrest frame 1. More specifically, a pair of parallel frame rods 11 are arranged on both sides of the backrest frame 1. A sliding assembly is arranged between the vertical rods 71 ​​on both sides of the sliding frame 7 and the frame rods 11. The sliding assembly has the following three structures:

[0035] 1. The vertical rod 71 extends outwardly with a clamping sleeve 72, which is slidably clamped on the frame rod 11 by means of the clamping sleeve 72 to form a sliding connection so that the vertical rod 71 can be lifted up and down under the action of external force; Figure 1 , Figure 4 and Figure 5 .

[0036] 2. Figure 6 and Figure 7The frame rod 11 is provided with a convex rail or groove 111 inwardly, and the vertical rod 71 is provided with a corresponding groove or convex rail 712 outwardly. The convex rail 712 is slidably inserted into the groove 111 to achieve track-type sliding fit.

[0037] 3. Figure 8 and Fig. 9 The frame rod 11 is a channel steel, and one side of the vertical rod 71 is fixed with more than two track wheels 713, and the track wheels 713 can be placed in the channel steel to form a rolling fit.

[0038] In addition to the three typical structures mentioned above, the sliding combination can also use any existing sliding support, such as: bare rod sliding sleeve, linear guide, etc.

[0039] Between the sliding frame 7 and the backrest frame 1, a driving mechanism 8 is provided to drive the sliding frame 1 to rise and fall. The driving mechanism 8 is an airbag, an electric push rod, or a cam driven by a motor. In this example, the driving mechanism 8 is an airbag, which is a one-way drive. It overcomes the weight of the sliding frame 7 and the massage movement 6 as a whole. The sliding frame 7 gradually rises during the inflation process, and slowly falls according to the weight during the deflation process. It can also control the inflation amount of the airbag to maintain the height of the sliding frame 7. The electric push rod can be controlled in both directions and has a long stroke, while the cam solution has a short stroke, but can achieve high-frequency reciprocating motion.

[0040] In order to install the driving mechanism 8 , a pair of parallel flat plates 12 are correspondingly welded to the lower ends of the backrest frame 1 and the sliding frame 7 , and the driving mechanism is arranged between the two flat plates 12 .

[0041] Sleeves 73 are symmetrically arranged on both sides of the sliding frame 7, a movement frame 61 is placed in the sleeve 73, and a spring 74 is padded between the movement frame 61 and the bottom of the sleeve 73 to form a floating support. The massage movement 6 is arranged on the movement frame 61. When the massage movement 6 is subjected to force, the spring 74 can be compressed and retreated to adapt the massage strength.

[0042] More specifically, a sleeve 73 is provided on the upper and lower inner sides of the two vertical rods of the sliding frame 7, and the sleeves 73 are paired in pairs to form a floating support for the movement frame 61; the floating support has the following two structures:

[0043] 1. The facing surfaces of the two sleeves 73 on the same side are provided with long grooves 731, and a pair of parallel support rods 62 are arranged on both sides of the movement frame 61. The two ends of the support rods 62 are respectively cut into the long grooves 731 and placed on the springs 74 to form a floating support for the support rods 62; in this structure, there are two or more massage movements 6 on the back, and a coaxial shaft section 611 is arranged in the middle of the movement frame 61. Each massage movement 6 can be rotatably positioned on the support rod 62 through its own shaft section 611. The massage movement 6 can pitch and swing relative to the support rod 62 to cater to the changes in the curved surface of the human back, and at the same time can follow the overall sinking or floating of the support rod 62, as well as unilateral floating, and the massage movement 6 has a better degree of freedom.

[0044] Second, the two sleeves 73 at the same end are provided with long grooves 731 on the facing surfaces, and the coaxial shaft sections 611 are provided in the middle of both sides of the movement frame 61. The shaft sections 611 are correspondingly cut into the long grooves 731 of the two sleeves at the same end and rest on the spring 74 to form a floating support for the massage movement 6. Compared with the above example, the support rod is omitted, so that the movement frame 61 carrying the massage movement is directly floated and positioned on the sleeve 73 through the shaft section 611, and can both pitch and swing and float up and down. Of course, if there are three groups of massage movements 6, three pairs of sleeves 73 need to be provided, and they are floated and positioned respectively.

[0045] Furthermore, the vertical rods 71 ​​on both sides of the sliding frame are provided with fixing plates 711 for hanging the backrest. In other words, the backrest cushion decoration can be directly locked on the fixing plates 711, and can be synchronously lifted and lowered with the sliding frame 7, so as to avoid the misalignment of the fabric and the built-in massage mechanism 6, and reduce the resistance during lifting and lowering. Of course, there is no need to fix the backrest cushion decoration on the backrest frame rod 11.
