Description

Technical Field

[0001] This utility model belongs to the field of massage chair technology, specifically a back vibration massage chair. Background Technology

[0002] Massage chairs are health care devices that use mechanical rolling force and air pressure to massage. Currently, more and more families are equipped with massage chairs for massage. When existing back massage chairs are working, the back massage mechanism is equipped with massage rollers. Massage is usually achieved by squeezing and tapping the massage rollers. Conventional massage methods are usually relatively light, and the diameter of the massage rollers is usually too large, which makes it impossible to accurately massage the painful areas of the back. For example, some people have severe pain in the scapula, trapezius, rhomboid muscles, etc., and cannot get effective relief from existing conventional massage chairs. Therefore, this application proposes a back vibration massage chair. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1 to 4 This invention discloses a back vibration massage chair, comprising a massage chair body 1, with a back massage mechanism 2 disposed inside the massage chair body 1. The back massage mechanism 2 consists of a support base plate 3, two mounting sleeves 4, a support box 5, four elastic limiting components 6, an angle adjustment component 7, and a massage component 8. The two mounting sleeves 4 are respectively welded to both ends of the support base plate 3 and installed inside the massage chair body 1. The four elastic limiting components 6 pass through the four corners of the support base plate 3 and are slidably connected to the support base plate 3. The support box 5 is fixedly connected to one end of the elastic limiting components 6. The angle adjustment component 7 passes through and is connected to the top of the support box 5. The massage component 8 passes through and is connected to both ends of the support box 5 and is connected to the angle adjustment component 7. The massage component 8 consists of a rotating shaft 9, a first support plate 10, a second support plate 11, several massage rollers 12, two multi-stage electric telescopic rods 13, and two pressing... The ball head 14 is formed. The rotating shaft 9 is rotatably connected to the support box 5 through bearings. The first support plate 10 and the second support plate 11 are symmetrically installed at both ends of the rotating shaft 9. The massage rollers 12 are rotatably connected to one side of the first support plate 10 and the second support plate 11 respectively. Two multi-stage electric telescopic rods 13 are respectively connected through the first support plate 10 and the second support plate 11. Two pressing ball heads 14 are respectively fixedly connected to the ends of the two multi-stage electric telescopic rods 13 away from the first support plate 10 and the second support plate 11. The angle adjustment component 7 is composed of a servo motor 15, a worm gear 16 and a worm wheel 17. The servo motor 15 passes through the top of the support box 5 and is fixedly connected to the support box 5. The worm gear 16 is rotatably connected to the inside of the support box 5 through bearings and is fixedly connected to the output shaft of the servo motor 15. The worm wheel 17 is fixedly connected to the rotating shaft 9 and meshes with the worm gear 16. The diameter of the pressing ball head 14 is 1cm.

[0022] During a regular massage, the multi-stage electric telescopic rod 13 is in the retracted state, such as... Figure 2 As shown, regular massage is achieved through the massage rollers 12. The mounting sleeve 4 is connected to the guide rail inside the massage chair body 1. The guide rail structure can adopt the commonly used structure inside existing massage chairs. If the user experiences severe pain in certain areas of their back, the servo motor 15 drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 to rotate. The worm wheel 17 then drives the rotating shaft 9 to rotate, causing the rotating shaft 9 to rotate the first support plate 10 and the second support plate 11. The first and second support plates 10 and 11 adjust the position of the multi-stage electric telescopic rod 13 and control its extension, allowing the pressing ball head 14 to contact the flexible padding of the massage chair. This provides targeted pressure massage to the user's back through the pressing ball head 14. The massage intensity is adjusted by controlling the extension distance of the multi-stage electric telescopic rod 13. Figure 3 As shown, because the size of the pressing ball 14 is small (only 1cm, while the size of conventional massage heads and massage rollers on the market is usually 3-10cm), it can have a better massage effect. It can accurately press on painful areas such as the scapula, trapezius, and rhomboid muscles of the back. The small size of the massage head can further increase the pressure (when the pressure is constant, the smaller the contact area, the greater the pressure), thereby improving the massage experience and effectively relieving pain. During the massage, the user can also adjust their own position laterally to massage specific points on the back.

[0023] The massage chair body 1 is fixedly equipped with a control panel 18, two first handles 19 and two second handles 20. The installation height of the second handles 20 is greater than that of the first handles 19. During massage, the user can limit the back by holding the first handles 19 or the second handles 20, so that the painful area of ​​the back is more closely fitted with the massage components, and further improve the massage effect.

[0024] Linear vibration motors 21 are fixedly installed at the middle positions of the top and bottom ends inside the support box 5. The elastic limiting component 6 consists of a limiting rod 22 and a spring 23. The limiting rod 22 is fixedly connected to the support box 5 and slides through the support base plate 3. The spring 23 is sleeved on the limiting rod 22 and located between the support box 5 and the support base plate 3.

[0025] During massage, the linear vibration motor 21 can be activated. The vibration direction of the linear vibration motor 21 coincides with the axis of the limiting rod 22. The limiting rod 22 and the spring 23 can have a buffering effect, further improving the massage effect through vibration.

[0026] In operation, the system utilizes a massage assembly consisting of a rotating shaft, a first support plate, a second support plate, several massage rollers, two multi-stage electric telescopic rods, and two pressing ball heads. It also incorporates an angle adjustment assembly comprised of a servo motor, a worm gear, and a worm wheel. This allows for conventional massage techniques. When a user experiences back pain, targeted pressure massage can be applied to the painful area, increasing massage intensity and effectively relieving pain, thus improving the user experience. The first and second handles allow for back support during massage, ensuring close contact between the back and the massage assembly and further enhancing massage intensity. A linear vibration motor and an elastic limiting assembly consisting of a limiting rod and a spring enable vibration massage, further improving the massage effect.
