[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1-Figure 2As shown, a novel modular massage cushion includes a first movement 10, a second movement 20, a first multifunctional rail 30, a second multifunctional rail 40, a first conductive foot 50, a second conductive foot 60, a first massage head 70 and a second massage head 80. The first movement 10 is slidably arranged on the first multifunctional rail 30, the first massage head 70 is arranged on the first movement 10, the second movement 20 is slidably arranged on the second multifunctional rail 40, the first conductive foot 50 is used to supply power to the first movement 10, the second massage head 80 is slidably arranged on the second movement 20, and the second conductive foot 60 is used to supply power to the second movement 20. For example, the first multifunctional rail 30 is provided with a first conductive surface 310, one end of the first conductive foot 50 is arranged on the first movement 10, and the other end of the first conductive foot 50 is slidably arranged on the first conductive surface 310. At least two first conductive surfaces 310 can be set on the upper and lower surfaces of the first multifunctional guide rail 30. Similarly, the second multifunctional guide rail 40 is provided with a second conductive surface 410. One end of the second conductive foot 60 is set on the second movement 20, and the other end of the second conductive foot 60 is slidably set on the second conductive surface 410. At least two second conductive surfaces 410 can be set on the upper and lower surfaces of the second multifunctional guide rail 40. The first conductive surface 310 and the second conductive surface 410 can be set with inlays or attachments of bare conductive copper sheets, or copper foil, or PCB circuits, or other conductive materials. The first multifunctional guide rail 30 and the second multifunctional guide rail 40 can both realize the two functions of creeping and conducting. The first multifunctional guide rail 30 and the second multifunctional guide rail 40 will deform to a comfortable back massage curve according to the pressure of body weight during massage. It also includes a power supply, a control terminal and a first conductive sheet. The first conductive sheet is arranged on the first multifunctional guide rail 30. One side of the first conductive sheet matches with the first conductive foot 50 to achieve electrical connection, and the other side of the first conductive sheet abuts with the power supply and the control terminal respectively to achieve electrical connection. Similarly, the second multifunctional guide rail 40 also adopts this connection method. The first conductive pin 50 and the second conductive pin 60 are fixed with an elastic copper sheet by a plastic frame, and riveted with a copper column or a carbon brush or other conductive material.

[0035] like Figure 2 , Figure 7 and Fig. 9 As shown, the first multifunctional rail 30 and the second multifunctional rail 40 can be set as a straight multifunctional rail, or a single-track curved helical conductive rail can be designed according to the waistline of the human body. The back and hips of the human body are wide and the waist is narrow. The module combination of the first movement 10 and the second movement 20 is more ergonomic, and it will deform according to the back curve during massage to achieve a more comfortable effect. The massage head movement is independent. When not massaging, the movement can be docked to the human shoulder according to the curved multifunctional rail to avoid hard objects on the back that affect the comfort.

[0036] like Figure 1-Figure 3As shown, in one embodiment, the first movement 10 includes a first upper shell 110, a first lower shell 120, a first motor 130, and a first gear set 140.

The first conductive foot 50 is slidably arranged on the first multi-functional guide rail 30 at one end outside the opening and abuts against the first conductive surface 310. The first conductive foot 50 is connected to the first massage head 70 and the first motor 130 at one end inside the opening, respectively, to heat the first massage head 70 and provide power for the rotation of the first motor 130.

[0037] In one embodiment, the first motor 130 drives the first gear set 140 to rotate, the first massage head 70 is disposed on the first gear set 140, and the first gear set 140 drives the first massage head 70 to rotate. For example, the first conductive pin 50 is electrically connected to the first motor 130, and the first motor 130 is powered by the first conductive pin 50, so that the first motor 130 drives the first gear set 140 to rotate.

[0038] like Figure 4-Figure 7 As shown, in one embodiment, the side of the first multifunctional guide rail 30 is provided with a first helical tooth 320, and the first helical tooth 320 meshes with the first gear set 140. For example, by providing the first helical tooth 320 on the side of the first multifunctional guide rail 30, the tooth surface contact line of the first multifunctional guide rail 30 can be changed from short to long during the meshing process, which is smoother than the meshing process of the straight teeth, reduces the impact, vibration, and noise, and the helical tooth meshing clearance is small, the structure is compact, the overlap is large, the bearing capacity is strong, and the service life of the first helical tooth 320 is extended. Similarly, the side of the second multifunctional guide rail 40 is provided with a second helical tooth 410, and the first helical tooth 320 and the second helical tooth 410 can be provided on the inside of the first multifunctional guide rail 30 and the second multifunctional guide rail 40 at the same time, and can also be provided on the outside.

The second motor 230 and the second gear set 240 are arranged in the second accommodating groove 240. The second multi-function guide rail 40 passes through the second accommodating groove 240. The second gear set 240 is respectively engaged with the second motor 230 and the second multi-function guide rail 40. The second motor 230 drives the second gear set 240 to slide on the second multi-function guide rail 40.

The third worm gear is provided with a fifth worm gear tooth and a sixth worm gear tooth. The second worm gear 143 is provided with a seventh worm gear tooth and an eighth worm gear tooth. The fifth worm gear tooth and the seventh worm gear tooth are respectively meshed with the second motor 230.

It can also be used as a sensing device to be sensed by the first movement 10. The rotation sensor 111 can be a light sensor or a Hall sensor. The bottom axis of the first massage head 70 is provided with a light screen 90 or a magnet to cooperate with the rotation sensor 111 to achieve synchronization or asynchrony of the rotation speed. The first movement 10 can synchronize the massage head massage and misalignment massage with the support of the crawling sensor 330 and the rotation sensor 111 signals. Massage, up and down crawling massage opposite to each other. In addition, the massage cushion is designed with a leather cover or a cloth cover on the outside, and the inside of the cover is provided with a partition for filling to ensure the comfort of the modular massage cushion. The first conductive foot 50 and the second conductive foot 60 are both provided with a supporting foot 510, and the supporting foot 510 can be conductive.
