In today's increasingly fast pace of life, people often use massage devices to massage the human body to promote blood circulation and relax the body. However, the existing massage chairs can only massage the human body's trunk and cannot massage the human head. Therefore, the experience effect is poor for mental workers.

[0003] To this end, technicians have designed an automatic massage chair that scans WeChat (patent publication number CN108618942A). A small head pad is set on the top of the massage chair body, and a head massage motor is installed in the middle of the small headrest. The head massage motor is used to massage the back of the user's head, but the head massage device cannot massage the rest of the head, so the massage effect is not ideal.

[0004] In this regard, the designers designed an all-round head massage chair (patent publication number CN108652931B), which includes a head massage device, a massage helmet, four massage blades, twelve electromagnetic generators, sixteen connecting chain plates, twenty-four connecting pins, twelve massage cylinders, and twelve electromagnetic induction motion steel balls. The four massage blades are symmetrically installed on the circumference of the side of the connecting plate, and the eight first hinge support plates are symmetrically installed on the four massage blades. The twenty-four connecting pins are fixedly installed on both sides of the twelve electromagnetic generators. The present invention adopts an electric cylinder, a motor and an electromagnetic field change linkage to realize the all-round massage action of the massage ball on the head. By changing the magnetic field of the electromagnetic generator, the principle of magnetic levitation is used to change the position of the electromagnetic induction steel balls at any frequency.

[0005] The above-mentioned head massage device is externally arranged on the outside of the massage chair body.

That is, when the user does not want to massage his head, he can also sit directly on the massage chair body 5 to ensure that the head massage device will not interfere with the user's head.

[0048] In some embodiments, two groups of shoulder massage mechanisms 6 are symmetrically arranged on the support frame 1, and the shoulder massage mechanism 6 includes a deflection component 61, a massage movement 62 arranged on the deflection component 61, and a fourth motor 63 that drives the massage movement 62 to deflect through the deflection component 61. The massage movement 62 includes a first arm 621 and a second arm 622 arranged at an angle, and a shoulder massage wheel 623 arranged on the first arm 621 and the second arm 622. The first arm 621 and the second arm 622 are hingedly arranged by a pivot 624, and the pivot 624 is provided with a The first torsion spring 625 is provided on the movement with a second limiting structure for limiting the rotational travel of the first arm 621 and the second arm 622. Specifically, the second limiting structure includes a support column 6211 arranged on the first arm 621 and a connecting plate 65 fixedly connected to the deflection assembly 61. An arc-shaped groove 651 is provided on the outer periphery of the connecting plate 65 corresponding to the position of the support column 6211.

[0049] In some embodiments, the deflection assembly 61 includes a deflection sleeve 611 and a positioning column 612, one end of the deflection sleeve 611 is eccentrically connected to a driving wheel located at the output end of the fourth motor 63. Specifically, two groups of driving wheels are horizontally arranged on the support frame 1, and the fourth motor 63 drives the two driving wheels to rotate in synchronous directions through a transmission mechanism. The other end of the deflection sleeve 611 is rotatably connected to a pivot 624 so that the massage movement 62 can rotate relative to the deflection sleeve 611. The pivot 624 is provided with a second torsion spring 626 for driving the massage movement 62 to reset. The positioning column 612 is arranged on the inner side of the two driving wheels corresponding to the support frame 1, and the deflection sleeve 611 is provided with a slide groove 6111 that guides the sliding of the positioning column 612. Through this arrangement, the kneading effect of the shoulder massage mechanism 6 is better when it deflects back and forth horizontally.

[0050] In this embodiment, a first sleeve 66 is fixedly installed at the end of the first arm 621, and a second sleeve 67 is fixedly installed at the end of the second arm 622. The walls of the first sleeve 66 and the second sleeve 67 are respectively provided with a first notch groove 661 and a second notch groove 662. The second notch groove 662 is an arc-shaped structure. A support column 6211 is provided on the first arm 621. A second torsion spring 626 is provided in the first sleeve 66 and is wound around one side of the pivot 624. A first torsion spring 625 is provided in the second sleeve 67 and is wound around the other side of the pivot 624.

Specifically, when the first support arm 621 and the second support arm 622 are subjected to the downward pressure of the human shoulder, the two arms will respectively rotate in the direction of compressing the first torsion spring 625 with the pivot 624 as the rotation axis. At this time, the angle between the first support arm 621 and the second support arm 622 is enlarged, and the first support arm 621 and the second support arm 622 are respectively rotated to a close position through the action of the first torsion spring 625. The massage effect of the shoulder massage wheels 623 on the two arms is improved by fitting the position of the human body's shoulders. When the user leaves the massage chair body 5, the first arm 621 and the second arm 622 will be reset (rotated in the direction of approaching each other) under the action of the first torsion spring 625. A third notch groove 6112 is provided on the deflection sleeve 611 of the deflection mechanism. The first end of the second torsion spring 626 in the first sleeve 66 extends out of the first notch groove 661 and extends into the third notch groove 6112 to abut against the groove wall of the third notch groove 6112.

The second end of the second torsion spring 626 can rotate along the second notch groove 662. Specifically, when the massage movement 62 (the first arm 621 and the second arm 622) are subjected to the downward pressure of the human shoulder, the two arms will rotate with the pivot 624 as the rotation axis. Specifically, the two arms will be biased toward one side of the first end of the compressed second torsion spring 626. Through the action of the second torsion spring 626, the two arms can be rotated together to a position that fits closely to the human shoulder, thereby improving the massage effect of the shoulder massage wheels 623 on the two arms. When the user leaves the massage chair body 5, the first arm 621 and the second arm 622 will be reset under the action of the second torsion spring 626.

[0051] The shoulder massage mechanism 6 on the massage chair of the present invention drives the massage movement 62 to oscillate back and forth laterally through the fourth motor 63 to simulate the kneading massage technique. At the same time, the shoulder massage mechanism 6 has an adaptive adjustment function, that is, the massage movement 62 (the first arm 621 and the second arm 622) can rotate synchronously relative to the support frame 1 with the pivot 624 as the rotation axis, and the massage movement 62 (the first arm 621 and the second arm 622) is driven to reset by the second torsion spring 626. At the same time, the first arm 621 and the second arm 622 can respectively rotate with the pivot 624 as the rotation axis, and have a tendency to approach each other under the action of the first torsion 625, which is used to simulate the kneading massage technique. Therefore, the shoulder massage mechanism 6 has a compact structure, a variety of massage techniques and a better massage effect.

[0052] In some embodiments, the shoulder massage mechanism 6 is provided with a sensor 64 for detecting whether the first arm 621 is rotated into place. The sensor 64 is fixedly connected to the deflection assembly 61. The sensor 64 is a through-beam infrared sensor 64. Specifically, the sensor 64 is provided with a notch, one end of the notch is a transmitting end, and the other end is a receiving end. The first arm 621 is arranged at a position corresponding to the notch. In the initial state, the through-beam infrared sensor 64 can detect infrared signals. When the first arm 621 rotates around the pivot 624 as the rotation axis toward the second end of the compression torsion spring 625 under the action of the user's shoulder, the first arm 621 will block the signal emitted by the transmitting end so that the receiving end cannot receive the signal. Through this arrangement, the position of the user's shoulder can be detected to adapt to users of different heights, and the human shoulder can be found more accurately, and then precise massage of the shoulder and neck can be performed.

[0053] In some embodiments, two groups of neck massage mechanisms 7 are symmetrically provided on the support frame 1, and the neck massage mechanism 7 includes a second connecting rod assembly 71, a third arm 72 and a neck massage wheel 73. The first end of the second connecting rod assembly 71 is hinged to the yaw sleeve 611, and the second end of the second connecting rod assembly 71 is hinged to the support frame 1. One end of the third arm 72 is rotatably connected to the second connecting rod assembly 71, and the other end of the third arm 72 is rotatably connected to the neck massage wheel 73. Specifically, the outer diameter of the neck massage wheel 73 is a structure that gradually expands from the inside to the outside, and neck kneading massage is achieved through the neck massage mechanism 7. The neck massage mechanism 7 on the massage chair of the present invention shares the same motor with the shoulder massage mechanism 6, so that the structure of the present invention is more compact, the volume is smaller, and the assembly is more convenient.
