Further, the massage chair further comprises a second drive assembly 800, and the second drive assembly 800 comprises a second electric push rod. The second electric push rod is provided with a fixed end and a push rod end. The fixed end of the second electric push rod is hinged to the third ear seat 110 disposed on the bottom frame assembly 100, and the push rod end of the second electric push rod is hinged to the fourth ear seat 220 disposed at the bottom of the backrest assembly 200. The inclination angle of the backrest assembly 200 of the massage chair can be adjusted by the second driving assembly 800, so as to ensure the comfort of the sitting posture of the user and the massage requirements of different inclination angles.

The working principle of the invention is as follows:

as shown in fig. 8, when the user's massage is finished, the components of the massage chair are restored to the original positions, as shown in fig. 4. When the first driving unit 600 starts to operate, the first electric push rod starts to extend, and the driving swing rod unit 400 is pushed to drive the movable seat frame 300 to move upward and outward, so that the user sitting on the movable seat frame 300 is sent forward as shown in fig. 9-11, and the inclination angle of the seat surface is changed, so as to straighten the body angle of the user, and when the first electric push rod operates to the sitting position (the most forward position) as shown in fig. 11, the position of the movable seat frame 300 is above the leg and foot massage unit 700, and the legs and feet of the user are removed from the leg and foot massage unit 700. The position at this moment can directly fall from the massage armchair, which is very convenient. When the user presses the control button after the user has come down, cradle 300 is returned to the initial position, as shown in fig. 4. When a user needs to use the massage chair, the control button is pressed first, the first driving unit 600 starts to operate, the movable seat frame 300 is moved to the sitting-up position (the most front position), the user directly sits on the movable seat frame 300, and then the first driving unit 600 moves the movable seat frame 300 to the initial position, so that the user can massage in a normal state.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
