Description

Technical Field

[0001] This application relates to the field of massage chair technology, and more particularly to massage chair mechanisms. Background Technology

[0002] A massage chair consists of the chair body and the massage mechanism, with the mechanism being the core component used to perform massage actions on the user. To enhance the massage effect, 3D massage chairs have been introduced to the market, which add back-and-forth movement to the original 2D massage to adjust the massage intensity.

[0003] refer to Figure 1 The existing 3D massage chair's mechanism includes a base 10A, a mechanism body 20A integrating massage arm assemblies and a kneading drive mechanism, a rotating shaft 30A, and a drive mechanism 40A. The base 10A includes a fixed part 11A and a movable part 12A. The mechanism body 20A is mounted on the movable part 12A. One end of the movable part 12A is connected to the rotating shaft 30A, and the rotating shaft 30A is mounted on the fixed part 11A. When the movable part 12A rotates around the axis of the rotating shaft 30A, it drives one end of the mechanism body 20A to move in the front-back direction, thereby adjusting the massage intensity. The drive mechanism 40A includes a drive motor, a reduction gearbox, a belt gear, and a sector gear. The sector gear is mounted on the mechanism body 20A, and the belt gear and sector gear are meshed. The output shaft of the drive motor is connected to the reduction gearbox, and the belt gear is sleeved on the output shaft of the reduction gearbox. The speed of the drive motor is reduced by the gearbox and then transmitted to the belt gear. The belt gear drives the movable part 12A to rotate around the axis of the rotating shaft 30A through the sector gear.

[0004] It is obvious that the structure of the drive mechanism 40A is relatively complex, which will increase the cost of the existing 3D massage chair's core mechanism. In addition, the overall structure that the drive mechanism 40A needs to drive is complex and heavy, so the driving energy required by the drive mechanism 40A will inevitably increase, leading to an increase in the energy consumption of the massage chair.

The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0025] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] refer to Figures 2 to 6 The massage chair mechanism according to a preferred embodiment of this application will be described in detail below.

[0028] refer to Figure 2 , Figure 3 and Figure 5 Specifically, the massage chair mechanism includes a base 10, a pair of massage arm assemblies 20, and a kneading drive mechanism 30. The base 10 is mounted on the backrest of the massage chair body, and the kneading drive mechanism 30 is mounted on the base 10. The two massage arm assemblies 20 are symmetrically distributed on both sides and are connected to the kneading drive mechanism 30. The kneading drive mechanism 30 drives the massage arm assemblies 20 to move, so that the massage arm assemblies 20 perform kneading actions.

[0029] refer to Figures 4 to 5 Each massage arm assembly 20 includes a fixed arm 21, a movable arm 22, at least one massage roller 23, and a telescopic adjustment component 24. The fixed arm 21 is connected to the kneading drive mechanism 30, the movable arm 22 is slidably mounted on the fixed arm 21, and the massage roller 23 is rotatably mounted on the movable arm 22. When the user's back is against the chair back, the massage roller 23 abuts against the user's back, so that the massage roller 23 acts on the user's back to massage the user's back.

[0030] The movable arm 22 is connected to the telescopic adjustment component 24. The telescopic adjustment component 24 drives the movable arm 22 to slide back and forth relative to the fixed arm 21, causing the movable arm 22 to move the massage roller 23 in the direction of pressing the user's back and away from the user's back. In this way, the telescopic adjustment component 24 adjusts the pressure applied to the back by the massage roller 23 by driving the movable arm 22 to slide relative to the fixed arm 21. Specifically, after the movable arm 22 drives the massage roller 23 to move a preset distance in the direction of pressing the user's back, the massage arm assembly 20 increases the pressure applied to the user's back; after the movable arm 22 drives the massage roller 23 to move a preset distance away from the user's back, the massage arm assembly 20 reduces the pressure applied to the user's back. The telescopic adjustment component 24 of this application directly drives the movable arm 22 to extend and retract relative to the fixed arm 21, and the movable arm 22 has a simple and lightweight structure, thus reducing the driving energy of the telescopic adjustment component 24.

[0031] Preferably, the telescopic adjustment component 24 includes a rack with a shifting mechanism 241, a rotating gear 242, and a drive motor 243. Either the rack with a shifting mechanism 241 or the rotating gear 242 is mounted on the fixed arm 21, and the other is mounted on the movable arm 22, with the rotating gear 242 and the rack with a shifting mechanism maintaining mesh. The drive motor 243 is connected to the rotating gear 242 so that the drive motor 243 drives the rotating gear 242 to rotate.

[0032] In one embodiment, the rack 241 is mounted on the fixed arm 21, and the rotating gear 242 is rotatably mounted on the movable arm 22. When the rotating gear 242 rotates, it slides relative to the fixed arm 21 under the constraint of the rack 241, causing the movable arm 22 to drive the massage roller 23 to move in the direction of pressing the user's back and away from the user's back.

[0033] In another embodiment, the rack 241 is mounted on the movable arm 22, and the rotating gear 242 is rotatably mounted on the fixed arm 21. When the rotating gear 242 rotates, it causes the rack 241 to slide relative to the fixed arm 21, thereby causing the movable arm 22 to move the massage roller 23 toward the direction of pressing the user's back and away from the user's back.

[0034] In some embodiments, the telescopic adjustment member 24 is implemented as a lockable cylinder, with the cylinder body mounted on the fixed arm 21 and the cylinder piston rod connected to the movable arm 22.

[0035] Compared with existing technologies, the telescopic adjustment component 24 has a simple structure and low cost, thereby reducing the manufacturing cost of the massage chair mechanism.

[0036] It is worth mentioning that the fixed arm 21 forms a sliding guide rail 211, which extends in the front-back direction, and the movable arm 22 is slidably mounted on the sliding guide rail 211, thereby improving the stability of the movable arm 22 when it moves.

[0037] Preferably, each of the massage arm assemblies 20 includes a plurality of massage rollers 23, which are spaced apart on the movable arm 22 along the height direction of the chair back, so as to increase the massage area of ​​the massage arm assembly 20 on the user and improve the massage effect.

[0038] Preferably, the movable arm 22 includes a lifting part 221 and a swing part 222, with the swing part 222 mounted on the lifting part 221. The massage wheel 23 is rotatably mounted on the swing part 222, and the lifting part 221 is drivably connected to the telescopic adjustment component 24.

[0039] In one embodiment, the lifting part 221 and the swing part 222 are integrally formed.

[0040] In another embodiment, the swinging part 222 is rotatably mounted on the lifting part 221. When the user sits on the massage chair and leans against the backrest, at least one of the massage rollers 23 is in close contact with the user's back. Under the pressure of the user's back, the pressed massage roller 23 drives the swinging part 222 to rotate relative to the lifting part 221. This causes the swinging part 222 to move the pressed massage roller 23 away from the user's back while the remaining massage rollers 23 move closer to the user's back. Thus, multiple massage rollers 23 can act on the user's back simultaneously, ensuring a massage effect. It is understood that different users have different body shapes. The swinging part 222 can adjust its posture according to the user's back shape, thereby improving the fit between the massage arm assembly 20 and the user's back, making the massage chair suitable for users of various body types.

[0041] refer to Figure 5 and Figure 6In one embodiment, the kneading drive mechanism 30 includes a first rotating shaft 31, a first driving member 32, and two mounting shafts 33. The first rotating shaft 31 is rotatably mounted on the base 10. The first driving member 32 is connected to the first rotating shaft 31 and drives the first rotating shaft 31 to rotate. The two mounting shafts 33 are respectively connected to the two end faces of the first rotating shaft 31, and the axis of the first rotating shaft 31 intersects the axis of the mounting shafts 33 at an angle. The end of the fixed arm 21 away from the movable arm 22 is rotatably sleeved on the mounting shaft 33. Specifically, when the first driving member 32 drives the first rotating shaft 31 to rotate, the first rotating shaft 31 drives the mounting shafts 33 to rotate, and then the mounting shafts 33 drive the fixed arm 21 to swing back and forth, thereby achieving the kneading and massaging function.

[0042] In one embodiment, the first driving component 32 includes a first driving motor 321, a first worm gear 322, and a first worm wheel 323. The first driving motor 321 is connected to the first worm gear 322, and the first worm wheel 323 is sleeved on the first rotating shaft 31. The first worm gear 322 and the first worm wheel 323 are engaged. When the first driving motor 321 drives the first worm gear 322 to rotate, the first worm gear 322 drives the first rotating shaft 31 to rotate via the first worm wheel 323.

[0043] Furthermore, the massage chair mechanism also includes a walking mechanism 40. The walking mechanism 40 includes a second rotating shaft 41, a second driving member 42, and a shifting gear 43. The second rotating shaft 41 is rotatably mounted on the base 10, and the second driving member 42 is connected to the second rotating shaft 41 to drive its rotation. The shifting gear 43 is sleeved on the second rotating shaft 41, and a rack is laid along the height direction on the chair back, with the shifting gear 43 meshing with the rack. When the second driving member 42 drives the second rotating shaft 41 to rotate, the second rotating shaft 41 drives the shifting gear 43 to rotate, and under the constraint of the rack, the shifting gear 43 drives the entire massage chair mechanism to move up and down the chair back, thus providing a comprehensive massage to the user's entire back.

[0044] It is worth mentioning that, due to the natural curvature of the human spine, the swinging part 222 can adjust its angle according to the curvature of each part when the massage chair mechanism moves up and down the backrest, so as to ensure that the massage roller 23 keeps in contact with the back.

[0045] In one embodiment, the second driving component 42 includes a second driving motor 421, a second worm gear 422, and a second worm wheel 423. The second driving motor 421 is connected to the second worm gear 422, and the second worm wheel 423 is sleeved on the second rotating shaft 41. The second worm gear 422 and the second worm wheel 423 are engaged. When the second driving motor 421 drives the second worm gear 422 to rotate, the second worm gear 422 drives the second rotating shaft 41 to rotate via the second worm wheel 423.

[0046] Preferably, the walking mechanism 40 further includes support wheels 44, which are rotatably mounted on both ends of the second belt shaft 41. A track is laid along the height direction on the chair back, and the support wheels 44 are rotatably mounted on the track to improve the stability of the massage chair mechanism's up-and-down movement.

[0047] Furthermore, the massage chair mechanism also includes a hammer-driving mechanism 50, to which the fixed arm 21 is connected. The hammer-driving mechanism 50 drives the massage arm assembly 20 to move, so that the massage arm assembly 20 performs a hammering action.

[0048] Specifically, the hammer-driving mechanism 50 includes a third belt shaft 51, a third drive component 52, two mounting shafts 53, an eccentric wheel 54, and a connecting rod 55. The third belt shaft 51 is rotatably mounted on the base 10. The third drive component 52 is connected to the third belt shaft 51 and drives the third belt shaft 51 to rotate. The two mounting shafts 53 are eccentrically connected to the two end faces of the third belt shaft 51, and the axis of the mounting shaft 53 is parallel to the axis of the third belt shaft 51. The mounting shaft 53 is rotatably mounted on the eccentric wheel 54. The connecting rod 55 has a ball head 551, which is rotatably mounted on the fixed arm 21. The end of the connecting rod 55 away from the fixed arm 21 is hinged to the eccentric wheel 54. When the third belt shaft 51 is driven to rotate by the third drive component 52, the third belt shaft 51 drives the assembly shaft 53 to rotate, the assembly shaft 53 drives the eccentric wheel 54 to float, and the eccentric wheel 54 pulls the fixed arm 21 to rotate back and forth around the first belt shaft 31 in a small amplitude through the connecting rod 55, so that the movable arm 22 moves back and forth, thereby achieving the massage function of hammering and tapping.

[0049] In one embodiment, the third drive component 52 includes a third drive motor 521, a belt 522, a drive pulley 523, and a driven pulley 524. The drive pulley 523 is sleeved on the output shaft of the third drive motor 521, and the driven pulley 524 is sleeved on the third belt shaft 51. The belt 522 is wound around the outer peripheral walls of the drive pulley 523 and the driven pulley 524, so that when the third drive motor 521 drives the drive pulley 523 to rotate, the drive pulley 523 drives the driven pulley 524 to rotate through the belt 522, thereby causing the third belt shaft 51 to rotate.

[0050] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented.
