Massage chair

Technical Field

The utility model relates to a therapeutic massage technical field, more specifically, the utility model relates to a massage armchair.

Background

Nowadays, with the continuous improvement of living standard and the gradual enhancement of health care consciousness of people, people pay more and more attention to the health care of their bodies. Various health-care massage products correspondingly appear in the market so as to meet the requirements of people on massage health care.

The massage chair is a common health-care massage product in daily life. In recent years, massage chairs have gradually entered ordinary consumer households. After heavy work, housework and the like, people can massage the human body by using the massage chair to achieve the health care effects of relaxing tense muscles, eliminating fatigue, promoting blood circulation, dredging channels and collaterals and the like. According to feedback, after people use the massage chair for massage, people can obviously feel that muscles are relaxed and joints are flexible, and can inspire people and have good effect on ensuring body health.

The massage machine core is a core component in the massage chair, and the performance of the massage machine core directly influences the performance of the massage chair, so technical personnel also continuously research the performance of the massage machine core. To current massage armchair, the massage core is reciprocal walking under running gear's drive usually, and the walking motor and the drive mechanism of control running gear operation set up on the massage core mostly, and this can cause the weight of massage core heavier, can increase the burden of massage core operation then. In addition, most massage chairs at present adopt a gear rack mechanism or a screw rod mechanism to realize the walking mechanism, and the mechanisms can realize linear walking. However, in order to ensure that the massage movement mechanism conforms to the curve of the human body better in the movement process, the walking track of the walking mechanism is not completely linear, but is curved or even irregular. However, when the gear transmission encounters an irregular curved track, the processing of the corresponding rack is troublesome, the mold opening by injection molding is needed, and the mold cost is quite high, which is quite poor for small-scale production. And the screw rod mechanism is adopted for transmission, so that the screw rod mechanism can only be used for linear motion, the curve motion track cannot be realized, the speed is difficult to increase, and the power loss is serious.

Therefore, there is a great need to develop a new massage movement structure to solve at least one of the problems of the prior art.
