Massage chair

Abstract

The invention relates to a massage chair. The massage chair is provided with a seat frame, a lower limb massage structure, a swinging driving structure and a telescopic driving structure, wherein the swinging driving structure can adjust the swinging angle of the lower limb massage structure relative to the seat frame, and the telescopic driving structure can adjust the telescopic quantity of the lower limb massage structure relative to the front end of the seat frame; the massage chair also comprises a data collector and a processor, wherein the data collector can collect first data information which is swinging angle or telescopic quantity information; the processor stores second data information corresponding to each swinging angle of the lower limb massage structure and the maximum telescopic quantity of the lower limb massage structure; the processor can receive the first data information and output driving signals according to the first data information and the second data information; the swinging driving structure and the telescopic driving structure can adjust the swinging angle and telescopic quantity of the lower limb massage structure according to the driving signals. The massage chair can precisely control the telescopic length and swinging angle of the lower limb massage structure of the massage chair, and avoids damage caused by extension and ground touching of the lower limb massage structure.
