Massage chair and massage machine core thereof

Abstract

The massage chair comprises a machine core frame, a kneading assembly, an adjusting assembly, a left massage crank arm and a right massage crank arm, the kneading assembly comprises a kneading shaft, the adjusting assembly comprises a rotating seat, and the massage chair is further provided with a knocking frame, a knocking motor, a transmission component, a first gear, a second gear and a knocking shaft; the knocking frame sleeves the kneading shaft and is fixedly connected with the rotating seat, the first gear sleeves the kneading shaft, the knocking shaft and the second gear are mounted on the knocking frame, the knocking shaft is movably connected with the rotating seat, and the second gear sleeves the knocking shaft, is fixedly connected with the knocking shaft and is in meshing transmission with the first gear. The knocking motor is arranged on the machine core frame and drives the first gear to rotate through the transmission part, so that the massage crank arm is driven to swing back and forth through the rotating seat to realize the knocking action; therefore, the massage machine core has the functions of containing the massage crank arms, adjusting the massage force, kneading and knocking.

Description

technical field [0001] The invention relates to the field of massage chairs, in particular to a massage chair and a massage movement thereof. Background technique [0002] Ordinary office chairs can only be used for daily sitting and do not have a massage function, so there are office chairs with massage functions, including a massage chair frame and a massage movement. There are guide rails on the massage chair frame, and the massage movement includes a mounting frame. , the mounting frame can slide up and down along the guide rail, and the mounting frame is equipped with a massage roller for massaging the human body, a kneading component for driving the massage roller for kneading, and a percussion component for driving the massage roller for percussion. There is a walking component that drives the mounting frame to move along the guide rail. The walking component includes an active walking shaft, a walking roller, a walking gear and a walking motor. The active walking sha...

AI Technical Summary

Problems solved by technology

[0005]1) The adjustment range of the massage force of the massage mechanism is small, which cannot meet the needs of a wide range of users;

[0006]2). When no massage is needed, the massage rollers protrude from the back of the massage chair, that is, when the user leans on the back of the massage chair, the massage rollers will It leans against the back of the human body, which seriously affects the comfort of the user

[0008] For the massage movement that can be accommodated by this kind of massage crank arm, when the massage crank arm is stored, the distance between the part of the massage crank arm used to install the percussion component and the percussion axis changes much larger than the range that the percussion component can adapt to. , that is, it is difficult for this type of massage movement to have a knocking function

[0009] The Chinese patent document whose publication number is CN111631930A discloses a massage chair and its massage core, including the core frame, two massage crank arms and a kneading assembly. The kneading assembly includes a kneading shaft and a kneading motor, and the massage crank arm It is sleeved on the kneading shaft and can rotate. The kneading motor drives the kneading shaft to rotate and makes the massage rollers on the two massage arms approach or move away from each other to realize the kneading action. It also includes empty sleeves on the kneading shaft The rotating base is equipped with a knocking shaft and a knocking motor, and two knocking connecting rods are set on the knocking shaft. The two knocking connecting rods are respectively connected with two massage crank arms, and the knocking motor drives The rotation of the percussion shaft drives the two massage crank arms to carry out the percussion action, and the adjustment motor installed on the movement frame drives the rotating seat to rotate, which in turn drives the massage crank arms to rotate around the kneading axis; The functions of massaging the crank arm, adjusting the massage strength, kneading and knocking; but the knocking components in this document are all installed on the rotating seat, which will make the structure on the rotating seat very complicated. During the movement, the inertia that needs to be overcome when the rotating seat knocks back and forth will also become very large, which seriously affects the service life of the motor, and puts forward high requirements on the material of the rotating seat and the kneading shaft; it is not conducive to saving costs
