Fix it. The foot pad 11 is made of rubber material. The present invention provides a plurality of strip grooves 12 on the bottom of the foot pad 11 to give the bottom of the foot pad 11 a wavy structure to increase the frictional force with the ground and prevent the massage chair from moving when in use. There is.

A method for controlling a rocking structure of a massage chair, the control method comprising the following steps.
In step S1, the drive mechanism 23 is controlled to rotate in the forward direction, the swing drive arm 22 is driven to swing in the forward direction from the lowest point, and the drive mechanism 23 is rotated in the forward direction. If the swing drive arm 22 is driven to swing before reaching the forward limit angle α1, the power of the drive mechanism 23 is turned off, and the swing drive arm 22 is caused to naturally return to the forward limit angle due to inertia. Raise it to α1.
In step S2, when the swing drive arm 22 reciprocates from the forward limit position to the lowest point, the process proceeds to step S3.
In step S3, the drive mechanism 23 is controlled to rotate in the opposite direction, the swing drive arm 22 is driven to swing in the forward direction from the lowest point, and the drive mechanism 23 is rotated in the reverse direction. If the swing drive arm 22 is driven to swing before reaching the reverse limit angle α2, the drive mechanism 23 is powered off, and the swing drive arm 22 is caused to naturally return to the reverse limit angle due to inertia. Raise it to α2.
In step S4, when the swing drive arm 22 reciprocates from the reverse limit position to the lowest point, the process proceeds to step S1.

When stationary, the support bracket 30 provided on the swinging mechanism 20 naturally retreats and is in its lowest position, and is located between the swinging driven arm 26, the mounting frame, the swinging drive arm 22, and the swinging bottom stand 21. An inverted isosceles trapezoidal structure is formed in , and the included angle β formed between the swing drive arm 22 and the vertical direction is 8.5° to 41.5°. It is optimal when the included angle β is 25°, and the initial kinetic energy of the drive motor 231 at startup can be reduced. In operation, the control mechanism 40 controls the drive motor 231 to rotate in a forward direction, causing the swing drive arm 22 to swing forward from its lowest point. In addition, since an angle α is formed between the longitudinal direction and the vertical direction of the pin groove 241, and 50°<α<70°, the initial kinetic energy of the drive motor 231 is further reduced, and the driving A motor 231 drives the swinging drive arm 22 to facilitate pendulum movement. When the drive motor 231 rotates in the forward direction and drives the swing drive arm 22 to swing before reaching the forward limit angle α1, the drive mechanism 23 is powered off and the swing drive arm 22 is turned off. The arm 22 is naturally raised to the forward limit angle α1 due to inertia. Thereafter, the swing drive arm 22 reciprocates in the opposite direction due to the gravitational force of the support bracket 30. When the swing drive arm 22 double-acts from the forward limit position to the lowest point, the control mechanism 40 controls the drive motor 231 to rotate in the opposite direction so that the swing drive arm 22 moves to the lowest point. It is driven to swing in the opposite direction. When the drive motor 231 rotates in the opposite direction and drives the swing drive arm 22 to swing before reaching the reverse limit angle α2, the power of the drive motor 231 is turned on and the swing drive arm 22 is turned on. The arm 22 is naturally raised to the reverse limit angle α2 due to inertia. Thereafter, the swing drive arm 22 reciprocates in the forward direction due to the gravitational force of the support bracket 30. When the swing drive arm 22 reciprocates from the reverse limit position to the lowest point, the above steps are repeated. This repeated motion realizes the swinging function.

Similarly, when the swing function is activated, the control mechanism 40 first controls the drive motor 231 to rotate in the opposite direction. The operating principle is the same as that for controlling the forward rotation of the drive motor 231. When the drive motor 231 rotates in the forward direction, the swing drive arm 22 swings, and the angle before reaching the forward limit angle α1 is defined as θ1. Here, the range of α1-θ1 is 1° to 3°. When the drive motor 231 rotates in the opposite direction, the swing drive arm 22 swings, and the angle before reaching the reverse limit angle α2 is defined as θ2. Here, the range of α2-θ2 is 1° to 3°. This prevents the feeling of failure and increases the level of comfort.

The above description is only the preferred embodiments of the present invention and is not used to limit the present invention, and those skilled in the art will be able to make various modifications and changes to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
