[0014] Beneficial effects of the present invention: (1) In the present invention, the massage core can be installed on a massage chair during use. When the user does not need massage, the massage head remains in a retracted state, at which time the surface of the chair can be kept flat, ensuring the comfort of the chair; when massage is needed, the massage head can move forward so that the convex surface of the chair presses against the human body, exerting a certain pressure on the human body to perform massage; at the same time, the massage core can also be used for other massages such as leg and waist massages; The brushless motor is used as the power source of the massage movement to drive the worm shaft to rotate, and then the worm shaft drives the kneading gear to rotate through the double gears, which can drive the kneading shaft to rotate. At this time, the massage head can be driven to rotate, thereby realizing the massage function. During the massage process, the massage head rotates, and massage is performed through the protrusions of different sizes above the massage head. At the same time, during the massage process, the adjustment plate controls the kneading shaft to move up and down, which can further control the massage head to move up and down, achieving a more comfortable massage effect. (2) Inflating the air bag with an air pump can lift up the adjustment plate, thereby adjusting the height of the adjustment plate. At the same time, the air bag is arranged in the support seat, and the support seat can ensure the inflation direction of the air bag, thereby ensuring the lifting effect of the adjustment plate. Similarly, the air bag can be fixed in the support seat by a cylindrical pin. At this time, the height of the massage head can be further adjusted by lifting the adjustment plate, so that the massage head can adjust the massage height, that is, the rapid inflation and deflation of the air bag can achieve acupressure. In addition, a first spring is sleeved on the kneading shaft, and the first spring is located between the lower cover of the movement and the adjustment plate; on the one hand, when the air bag is not working, the first spring is in a released state, and the massage head can be pulled back to the lowest position. On the other hand, when the air bag is working, the adjustment plate is lifted up. Since the massage head needs to perform massage, when the massage movement contacts the human body and bears the pressure of the human body, the massage head will be pressed down. At this time, the first spring can be contracted, that is, during the massage of the air bag inflation process, the first spring can prevent the massage head from extending too far and generating a large massage force, which affects the massage experience, and further plays a role in protecting the air bag; (3) A plurality of guide shafts 6 are arranged in a rectangular array inside the support seat 15. One end of the guide shaft 6 is fixedly connected to the lower cover 10 of the movement, and the other end is fixedly connected to the support seat 15. At this time, a second spring 91 is sleeved on the guide shaft 6. The second spring 91 is located between the lower cover 10 of the movement and the adjustment plate 11. By sleeve-arranging the second spring 91 on the guide shaft 6 and locating it between the lower cover 10 of the movement and the adjustment plate 11, on the one hand, the massage experience is improved. On the other hand, the first spring 9 is replaced by the second spring 91 and sleeved on the guide shaft 6. At the same time, the retaining spring 12 at the connection between the end of the kneading shaft 5 and the adjustment plate 11 is adjusted to be rotatably connected to the shaft sleeve 121, so as to avoid friction between the kneading shaft 5 and the first spring 9 during the process of moving up and down and rotating at the same time, thereby affecting the stability of the overall structure of the massage movement. This not only ensures the stability of the internal structure of the massage movement, but also improves the massage experience. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] Embodiment 1 See also Figure 1-Figure 4As shown, the present invention is an adjustable height massage movement, including a support seat 15 and an air pump 18, an adjustment plate 11 is slidably arranged inside the support seat 15, and a kneading shaft 5 is symmetrically rotatably arranged at both ends of the adjustment plate 11, and the kneading shaft 5 is a flat shaft, that is, a non-cylindrical shaft symmetrically arranged on both sides with a plane, and the end of the kneading shaft 5 is rotatably connected to the adjustment plate 11 and limited by a retaining spring 12, and the up and down movement of the kneading shaft 5 can be controlled by the adjustment plate 11 without affecting the rotation of the kneading shaft 5; A lower movement cover 10 is fixedly arranged above the support seat 15, an upper movement cover 2 is fixedly arranged above the lower movement cover 10, and a massage head 1 is symmetrically rotated above the upper movement cover 2. Hemispherical protrusions of different sizes can be arranged on the massage head 1 to achieve a massage function. The massage protrusions are designed to be hemispherical to increase comfort. The kneading shaft 5 passes through the lower cover 10 of the movement, the upper cover 2 of the movement and is connected to the massage head 1. The adjustment plate 11 can move up and down to push the two kneading shafts 5 to move up and down, thereby achieving the up and down adjustment of the massage head 1.
[0020] Specifically, a kneading gear 7 is symmetrically rotated inside the lower cover 10 of the movement, and the kneading shaft 5 is slidably connected to the kneading gear 7. The kneading gear 7 is used to provide power for the rotation of the kneading shaft 5. However, the kneading shaft 5 can move up and down with the lifting and lowering of the adjustment plate 11 during the rotation process, but the kneading gear 7 does not move with the up and down movement of the kneading shaft 5. Therefore, the kneading shaft 5 is designed as a flat shaft, and the kneading gear 7 is slidably connected to the kneading shaft 5; It should be noted that the shape of the shaft is not limited to the flat shaft in this embodiment, and may also be other shapes that can simultaneously rotate axially and move radially, such as a polygon, or use a latch structure; Then, a double gear 4 is symmetrically arranged inside the lower cover 10 of the movement, wherein the upper gear of the double gear 4 is a helical gear and the lower gear of the double gear 4 is a spur gear; The lower wheels of the two double gears 4 are meshed and connected with the two kneading gears 7 respectively; At the same time, a brushless motor 3 is fixedly arranged inside the lower cover 10 of the movement, and a worm shaft 8 is fixedly arranged at the output end of the brushless motor 3, and both sides of the worm shaft 8 are respectively meshed and connected with the upper wheels of the double gear 4; The brushless motor 3 is used as the power source of the massage movement to drive the worm shaft 8 to rotate, and then the worm shaft 8 drives the kneading gear 7 to rotate through the double gear 4, which can drive the kneading shaft 5 to rotate. At this time, the massage head 1 can be driven to rotate, thereby realizing the massage function. During the massage process, the massage head 1 rotates, and massage is performed through the protrusions of different sizes above the massage head 1. At the same time, during the massage process, the adjustment plate 11 controls the kneading shaft 5 to move up and down, which can further control the massage head 1 to move up and down, thereby achieving a more comfortable massage effect.
[0021] During use, the massage movement can be installed on a massage chair. When the user does not need massage, the massage head 1 remains in a retracted state. At this time, the surface of the chair can be kept flat to ensure the comfort of the chair. When massage is needed, the massage head 1 can move forward to make the surface of the chair bulge against the human body, exerting a certain pressure on the human body to perform massage. At the same time, the massage movement can also be used for other massages such as leg and waist massage.
[0022] Among them, the adjustment plate 11 controls the kneading shaft 5 to move up and down. In order to further increase the massage effect during the movement, this embodiment provides the following technical solutions to achieve the up and down movement of the kneading shaft 5, while further improving the massage effect and increasing the experience; Specifically: a plurality of lifting support columns 151 are arranged in a rectangular array inside the support seat 15. When the adjustment plate 11 is installed inside the support seat 15, the adjustment plate 11 is slidably connected with the lifting support columns 151. The lifting support columns 151 are limited to ensure that the adjustment plate 11 can achieve stable movement during the up and down movement, thereby avoiding the adjustment plate 11 from deviating during the up and down movement, thereby preventing the kneading shaft 5 from moving unstably, thereby improving the stability of the overall structure of the device during the massage process. In addition, an air bag 14 is arranged inside the support seat 15 and below the adjustment plate 11. The air bag 14 is connected to the air pump 18 through an air pipe 17, and an air valve 16 is arranged on the air pipe 17. During the massage process, the air bag 14 is inflated by the air pump 18 to achieve the effect of lifting the adjustment plate 11, thereby adjusting the height of the adjustment plate 11. At the same time, the air bag 14 is arranged in the support seat 15, and the support seat 15 can ensure the bulging direction of the air bag 14, thereby ensuring the effect of the adjustment plate 11 rising. Similarly, the air bag 14 can also be fixed in the support seat 15 by a cylindrical pin. At this time, the height of the massage head 1 can be further adjusted by lifting the adjustment plate 11, so that the massage head 1 can achieve the adjustment of the massage height, that is, the rapid flushing and deflation of the air bag 14 can achieve finger pressure. In addition, a first spring 9 is sleeved on the kneading shaft 5, and the first spring 9 is located between the lower cover 10 of the movement and the adjustment plate 11; on the one hand, when the air bag 14 is not working, the first spring 9 is in a released state, and the massage head 1 can be pulled back to the lowest position. On the other hand, when the air bag 14 is working, the adjustment plate 11 is lifted up. Since the massage head 1 needs to perform massage, when the massage movement contacts the human body and bears the pressure of the human body, the massage head 1 will be pressed down. At this time, the first spring 9 can shrink, that is, during the massage in the process of inflation of the air bag 14, the first spring 9 can prevent the massage head 1 from extending too far and generating a large massage force, which affects the massage experience and further plays a role in protecting the air bag 14.
[0023] In addition, it can be explained that after the air bag 14 is working, the air bag 14 can be inflated and deflated in an orderly manner to achieve height adjustment of the adjustment plate 11, thereby driving the height adjustment of the massage head 1. Since the air bag 14 is located between the adjustment plate 11 and the support seat 15, the support seat 15 plays a role in supporting the air bag 14, and the support seat 15 is fixedly connected to the lower cover 10 of the movement. The rising height of the adjustment plate 11 can be limit-controlled using an air pressure sensor or a travel switch, and the travel switch can be set below the lower cover 10 of the movement.
[0024] Embodiment 2 Reference Figure 5-Figure 7 As shown, in this embodiment, compared with the first embodiment, a plurality of guide shafts 6 are arranged in a rectangular array inside the support seat 15, one end of the guide shaft 6 is fixedly connected to the movement lower cover 10, and the other end is fixedly connected to the support seat 15. At this time, a second spring 91 is sleeved on the guide shaft 6, and the second spring 91 is located between the movement lower cover 10 and the adjustment plate 11; In this design structure state, the design of the air bag 14 is adjusted accordingly compared with the structure in the first embodiment. At this time, the four corners of the air bag 14 are designed to be arc-shaped. At this time, the air bag 14 can be stably located below the adjustment plate 11 without deviation during the inflation and deflation process, thereby ensuring the stability of the adjustment plate 11 in lifting and lowering. During the massage process, since the second spring 91 is sleeved on the guide shaft 6, when the air bag 14 is not working, the second spring 91 is in a released state, and the second spring 91 applies downward pressure to the adjustment plate 11 to ensure that the air bag 14 is in a contracted state. When the air bag 14 is working, the air bag 14 lifts up the adjustment plate 11, thereby controlling the massage head 1 to move upward, thereby achieving a finger pressure massage effect. Since the massage movement is in contact with the human body and bears the pressure of the human body, the massage head 1 will be pressed down. At this time, the second spring 91 can achieve a buffering effect and avoid the air bag 14 from rupturing due to a large squeezing force, thereby improving the massage experience and ensuring the stability and safety of the massage movement. By sleeve-arranging the second spring 91 on the guide shaft 6 and locating it between the lower cover 10 of the movement and the adjustment plate 11, on the one hand, the massage experience is improved, and on the other hand, the first spring 9 is replaced by the second spring 91 and sleeved on the guide shaft 6, and at the same time, the retaining spring 12 at the connection between the end of the kneading shaft 5 and the adjustment plate 11 is adjusted to be rotatably connected with the sleeve 121, so as to avoid friction with the first spring 9 during the process of the kneading shaft 5 moving up and down and rotating at the same time, which affects the stability of the overall structure of the massage movement, thereby ensuring the stability of the internal structure of the massage movement and improving the massage experience.
[0025] Embodiment 3 Based on the technical solutions in the above embodiments, Figure 8 As shown, this embodiment provides the following technical solution: The massage head 1 comprises a lower cover 10 of the movement, a upper cover 2 of the movement is fixedly arranged above the lower cover 10 of the movement, and a massage head 1 is symmetrically arranged and rotated above the upper cover 2 of the movement, and hemispherical protrusions of different sizes are arranged on the massage head 1 to realize the massage function, and the massage protrusions are designed to be hemispherical to increase the comfort; The kneading shaft 5 passes through the lower cover 10 of the movement, the upper cover 2 of the movement and is connected with the massage head 1. The kneading gear 7 is symmetrically rotated inside the lower cover 10 of the movement. The kneading shaft 5 is slidably connected with the kneading gear 7. The kneading gear 7 is used to provide power for the rotation of the kneading shaft 5, but the kneading gear 7 does not move with the up and down movement of the kneading shaft 5. Therefore, the kneading shaft 5 is designed as a flat shaft, and the kneading gear 7 is slidably connected with the kneading shaft 5. The end of the kneading shaft 5 is connected to the massage head 1, and a suspension 142 is provided on the kneading shaft 5 and below the massage head 1, and then a single air bag 141 is provided between the suspension 142 and the upper cover 2 of the movement, and the middle part of the kneading shaft 5 passes through the single air bag 141, and the middle part of the single air bag 141 does not contact the kneading shaft 5; The two single air bags 141 are connected to the air pump 18 through the air pipe 17 respectively; Then, a double gear 4 is symmetrically arranged inside the lower cover 10 of the movement, wherein the upper gear of the double gear 4 is a helical gear and the lower gear of the double gear 4 is a spur gear; The lower wheels of the two double gears 4 are meshed and connected with the two kneading gears 7 respectively; At the same time, a brushless motor 3 is fixedly arranged inside the lower cover 10 of the movement, and a worm shaft 8 is fixedly arranged at the output end of the brushless motor 3, and both sides of the worm shaft 8 are respectively meshed and connected with the upper wheels of the double gear 4; Then, a third spring 93 is sleeved on one end of the kneading shaft 5 located inside the upper cover 2 and the lower cover 10 of the movement; At this time, when the single airbag 141 is inflated to lift the suspension 142, the massage head 1 can be further lifted to achieve the lifting and lowering of the massage head 1. At the same time, the massage head 1 can still keep rotating. At this time, the massage head 1 rises and the third spring 93 is in a contracted state. When the massage head 1 needs to be lowered, the single airbag 141 is deflated, and the third spring 93 is reset to retract the massage head 1. In this solution, the space occupied by the massage movement is saved, and there is no need to set up a support base 15. The height of the massage head 1 is controlled by two single air bags, which increases the use range of the massage movement, greatly reduces the space, and has a wider applicability, such as pillows, lumbar supports and other scenarios.
[0026] Working principle of the present invention: When in use, the brushless motor 3 drives the worm shaft 8 to rotate, and then the worm shaft 8 drives the kneading gear 7 to rotate through the double gear 4, which can drive the kneading shaft 5 to rotate, and at this time, the massage head 1 can be driven to rotate, thereby performing massage; During the massage process, the air bag 14 is inflated by the air pump 18 to lift up the adjustment plate 11, thereby adjusting the height of the adjustment plate 11. The adjustment plate 11 can be raised and lowered to further adjust the height of the massage head 1, so that the massage head 1 can adjust the massage height. At the same time, the rapid inflation and deflation of the air bag 14 can achieve acupressure massage.
