Referring to fig. 5, the moving driving mechanism 4 is disposed at the lower end of the lead screw 3, and includes a driving face gear 41, a first driving motor 42 and a driving wheel 43, where the first driving motor 42 is connected with the driving wheel 43, and at least one group of the first driving motor 42 and the driving wheel 43 is disposed. The drive capstan 43 is engaged with the drive face gear 41. The driving face gear 41 is connected to one end of the screw 3, and the driving face gear 41 can drive the screw 3 to rotate.

The massage mechanism 2 comprises a screw nut 21, a support frame 22, a moving face gear 23, a moving driven wheel 24 and a massage driving assembly.

The screw nut 21 is provided on the screw 3, and when the screw 3 rotates, the screw nut 21 can linearly move along the axis of the screw 3.

Referring to fig. 6, the support frame 22 includes a cross bar 221 extending in the left-right direction and having a right end connected to the screw nut 21, a longitudinal bar 222 extending in the front-rear direction and having a middle connected to the left end of the cross bar 221, and an L-shaped motor bracket 223 connected to the cross bar 221. The transverse rod 221 is rotatably connected with a movable face gear 23, two ends of the longitudinal rod 222 are respectively provided with a movable driven wheel 24 meshed with the movable face gear 23, two movable driven wheels 24 are respectively connected with a flexible shaft 27, one end, far away from the movable driven wheel 24, of each flexible shaft 27 is clamped in a groove of a corresponding side curve guide rail 111, at least one flexible cam 28 is arranged on each flexible shaft 27, the motor support 223 is further provided with a massage driving assembly, the massage driving assembly can drive the movable face gear 23 to rotate, and further the movable driven wheel 24 and the flexible shafts 27 are driven to rotate, and the flexible cams 28 can massage the back of a human body in the rotation process of the flexible shafts 27.

Specifically, as shown in fig. 4, the massage drive assembly includes a second drive motor 26 and a massage drive gear 25, wherein the massage drive gear 25 is meshed with the moving face gear 23.

Specifically, the flexible cams 28 are all made of soft materials, such as plastics, rubber, and the like. The flexible shaft 27 is made of plastic.

The working process of the electric massage chair in the invention is as follows:

When the electric massage chair works, an external power supply or a battery is needed to provide electric energy to drive the first driving motor 42 to rotate, the first driving motor 42 drives the driving wheel 43 to rotate, and then the driving wheel 43 drives the driving face gear 41 in the movable driving mechanism 4 to rotate, and the driving face gear 41 drives the screw rod 3 to rotate. The screw nut 21 is arranged on the massage mechanism 2, the screw nut 21 is arranged on the screw 3, and because the massage mechanism 2 cannot rotate, the screw nut 21 can only linearly move along the axis of the screw 3 when the screw 3 rotates, so that the massage mechanism 2 can move up and down along the axis of the screw 3, namely, the massage position can move up and down, and a better massage effect can be achieved. The second driving motor 26 is connected to the screw nut 21 through a motor bracket 223, and the second driving motor 26 is driven by electric energy to rotate, so as to drive the massage driving gear 25 to rotate, and the moving face gear 23 can be driven to rotate through a meshing relationship. The movable driven wheels 24 are disposed at two ends of the longitudinal bar 222 in the support frame 22 and meshed with the movable face gear 23, so that the movable face gear 23 can drive the movable driven wheels 24 to rotate when rotating. The movable driven wheels 24 are respectively connected with one end of a flexible shaft 27, when the movable driven wheels 24 rotate, the flexible shaft 27 can be driven to rotate, and the other end of the flexible shaft 27 is arranged in a groove of the curve guide rail 111 and can move up and down along the groove of the curve guide rail 111. The flexible cam 28 is provided on the flexible shaft 27 and can rotate synchronously with the flexible shaft 27. When the flexible shaft 27 rotates, the protruding height of the flexible cam 28 becomes smaller and larger, so that the effect of massaging the human hand can be simulated. In the running process of the massage mechanism 2, the screw rod 3 drives the massage mechanism 2 to move up and down, so that the whole massage of the back of the human body is realized, and the optimal massage effect can be achieved. By providing a plurality of flexible cams 28 on the flexible shaft 27, simultaneous massage of a plurality of massage points can be easily achieved, and the massage effect is better.

The above description is only of the preferred embodiment of the present invention, and is not intended to limit the present invention in any way. All equivalent changes or modifications made according to the essence of the present invention should be included in the scope of the present invention.
