Description

Driving device for self-adaptive curved surface massage Technical Field The invention relates to the technical field of massage equipment, in particular to a driving device for self-adaptive curved surface massage. Background Massage is an effective physical therapy, and can relieve muscle fatigue, promote blood circulation, and improve soft tissue state. In recent years, household and commercial massage devices have become increasingly popular, however, there are still significant technical drawbacks to the drive mechanisms of existing massage devices. Firstly, the prior massage device has limited freedom of movement, and is difficult to be attached to the back curve of a human body. The back of the human body is not a plane, but has complex three-dimensional curved surface characteristics such as spine depression, scapula bulge, lumbar curvature and the like. At present, most massage chairs adopt a walking mechanism with a fixed track, and the massage wheels can only move up and down in the vertical direction or can swing in a simple plane within a small range, so that the curved surface of each area of the back cannot be covered and attached accurately. Secondly, the existing equipment has insufficient adjustment capability on the distance between the massage wheels. The back width difference of users with different body types is obvious, and factors such as shoulder width, latissimus dorsi development degree and the like determine the optimal contact position of the massage wheel and muscles on two sides of the spine. The distance between two groups of massage wheels of the traditional massage equipment is mostly fixed or can only be manually roughly adjusted, and the massage effect and the comfort level can not be seriously influenced according to the dynamic adaptation of the body type of a user in the use process. Furthermore, the conventional driving mechanism has a single massage mode, and is capable of simulating a partial massage technique, but lacks an action mode simulating "beating" and "tapping" of a human hand. Some devices attempt to swing through an eccentric wheel or a crank, but the swing amplitude, frequency and limit control are not accurate enough, so that the beating action is hard and the impact feeling is strong, comfortable experience cannot be achieved, and the physiotherapy effect of the massage device is limited. Therefore, a novel massage driving device is urgently needed in the field, and flexible movement of the massage wheel at any position of the back can be realized, so that the curved surface of the back of a human body is comprehensively adapted, and the massage comfort level is improved.
