[0041] The following description will be made in conjunction with the accompanying drawings Figure 1 - the accompanying drawings Figure 7 The utility model will be further described in detail.

[0042] Embodiment, a seat electric lifting massage chair frame, refer to Figure 1 , including the chassis 11, and the chassis 11 is metal framework structure;The chassis 11 is provided with two lower sliding grooves 52, and the two lower sliding grooves 52 are located at the both sides of the chassis 11 and are connected;

[0043] The chassis 11 is provided with two symmetrically arranged upper sliding grooves 42, and the upper sliding grooves 42 are located above the lower sliding grooves 52.

[0044] The upper sliding groove 42 is communicated with the connecting sliding groove 62.The upper sliding groove 42 and the connecting sliding groove 62 are formed by bending through the concave track, and the upper sliding groove 42 is inclinedly arranged relative to the connecting sliding groove 62.

[0045] Refer to Figures 1-2 , the chassis 11 is slidably provided with a back frame 12, and the back frame 12 is installed with an upper roller 41 and a lower roller 51;The both sides of the back frame 12 are provided with a first rotating shaft 31, and the first rotating shaft 31 is installed with the upper roller 41.

[0046] The upper roller 41 slides in the upper sliding groove 42, and the lower roller 51 slides in the lower sliding groove 52.The circumferential side of the lower roller 51 is recessed, and the lower sliding groove 52 is composed of tracks arranged in the upper and lower directions, and the recess on the circumference of the lower roller 51 is embedded in the track of the lower sliding groove 52, so that the shaking during the position adjustment of the back frame 12 can be reduced.

[0047] Therefore, the back frame 12 can slide along the upper sliding groove 42 and the lower sliding groove 52, and the vertical inclination angle adjustment can be carried out.

[0048] And the power source for the angle adjustment of the back frame 12 comes from the first electric drive device 21;

[0049] The first electric drive device 21 is fixed on the chassis 11, the first electric drive device 21 is an electric push rod, and the pushing piece of the first electric drive device 21 is hingedly connected with a connecting rod 23, and the connecting rod 23 is rotatably connected with the back frame 12;The horizontal movement of the first electric drive device 21 drives the connecting rod 23 to swing, and at the same time drives the back frame 12 to adjust the vertical inclination angle.

[0050] The back frame 12 is installed with a connecting frame 13, and the connecting frame 13 will be adjusted in angle along with the back frame 12;

[0051] The specific structure of the connecting frame 13 is described with reference to Figure 1 、 Figure 3 and Figure 4 The two connecting frames 13 are rotatably connected to the second rotating shafts 32.

[0052] The connecting frame 13 is rotatably connected to the connecting roller 61, and the bottom frame 11 is provided with a connecting sliding groove 62 for the sliding of the connecting roller 61.

[0053] The two connecting sliding grooves 62 are arranged oppositely, and the connecting frame 13 is provided with an inner rod 81 and an outer rod 82.

[0054] Therefore, one end of the connecting frame 13 is rotatably connected to the back frame 12, and the other end is rotatably connected along the track of the connecting sliding groove 62.

[0055] Therefore, when the back frame 12 as the driving part is stationary, the connecting frame 13 is also stationary synchronously.

[0056] Therefore, when the back frame 12 as the driving part swings, the connecting frame 13 also swings.

[0057] The connecting frame 13 is used by the user, and the angle of the connecting frame 13 cannot be adjusted independently.

[0058] Referring to Figure 1 、 Figure 5 and Figure 6 The upper seat frame 14 is rotatably connected to the second rotating shaft 32.

[0060] The connecting frame 13 is provided with a second electric driving device 22 for driving the upper seat frame 14 to vertically flip to adjust the sitting angle.

[0061] The second electric driving device 22 is an electric push rod, and the two ends of the second electric driving device 22 are respectively hinged to the connecting frame 13 and the upper seat frame 14.

[0062] Therefore, when the second electric driving device 22 is extended, the upper seat frame 14 is rotated upward relative to the connecting frame 13 and unfolded.

[0063] When the second electric driving device 22 is retracted, the upper seat frame 14 is rotated downward relative to the connecting frame 13 and folded.

[0064] Therefore, the angle of the upper seat frame 14 relative to the back frame 12 can be adjusted independently by the second electric drive device 22.

[0065] Further, the upper seat frame 14 is fixed with upper blocking rods 7, which are L-shaped and welded inside the upper seat frame 14; the upper blocking rods 7 are located above the connecting frame 13.

[0066] When the second electric drive device 22 drives the upper seat frame 14 to the bottom, the upper blocking rods 7 abut against the upper surface of the connecting frame 13.

[0067] In the design, the bottom frame 11, the back frame 12, the connecting frame 13 and the upper seat frame 14 are all metal frames, and in other embodiments, they can all be plastic frames or wooden frames, etc.; the electric drive devices are all electrically driven; and the upper seat frame is a seat part.

[0068] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical solution falling within the idea of the present application belongs to the protection scope of the present application. It should be noted that for ordinary skilled in the art, some improvements and refinements without departing from the principle of the present application are also considered to be within the protection scope of the present application.
