Description

[0002] Massage chairs are a common type of health care massage product in daily life. In recent years, massage chairs have gradually entered ordinary consumer households. After heavy work and housework, people can use massage chairs to massage the body to achieve health care effects such as relaxing tense muscles, eliminating fatigue, promoting blood circulation, and unblocking meridians. Among them, the massage movement is one of the important components of the massage chair, and its performance will directly affect the performance of the massage chair.

[0003] The common massage chairs on the market, especially those with two upper and lower massage balls on the left and right massage arms, are generally used as a whole. When the massage machine realizes the 3D massage function, the two massage balls move upward or downward relative to the back of the human body. In this process, since the 3D radial motion rotates around a rotation point outside the massage arm, the lower massage ball on the massage arm that is closer to the rotation point has a small rotation radius. Under the same rotation angle, the arc length of the motion caused by its rotation is small, resulting in insufficient back massage by the lower massage ball, poor human massage experience, and poor massage intensity control. Therefore, how to provide a massage chair that can achieve both human body curves and massage intensity to achieve a good massage effect for users of different body shapes is a technical problem that needs to be solved urgently.

[0033] In the description of the present invention, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "installed", "connected", "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Please refer to Figures 1 to 3, this embodiment provides a massage mechanism, which includes a crankshaft drive mechanism 10, a connecting rod drive mechanism 20, a frame 30, and a kneading mechanism 40 provided on the frame 30; the crankshaft drive mechanism 10 and the connecting rod drive mechanism 20 are respectively provided on the frame of the massage mechanism, and the opposite sides of the frame 30 are respectively rotatably connected to the crankshaft drive mechanism 10 and the connecting rod drive mechanism 20. The crankshaft drive mechanism 10 is used to drive one end of the frame 30 to move relative to the frame, and the connecting rod drive mechanism 20 is used to drive the other end of the frame 30 to move relative to the frame. This massage mechanism can adjust the radial massage force, so that the massage mechanism can apply variable massage forces to the user, realize more diverse massage techniques, and improve the user experience.

[0035] Among them, the kneading mechanism 40 provided in this embodiment can massage and knead the user's back, shoulders, etc. It can perform overall massage on the entire back and shoulders of the user, or massage the acupoints on the back and shoulders of the user. The specific massage method is not limited in this application, and those skilled in the art can set it according to their needs.

[0036] Specifically, the kneading mechanism 40 is provided on the frame 30 of the massage mechanism. This application also provides a crankshaft drive mechanism 10 and a connecting rod drive mechanism 20. Among them, the crankshaft drive mechanism 10 is rotatably connected to one side of the frame 30, and the connecting rod drive mechanism 20 is connected to the other side of the frame 30, as Figure 2 shown, Figure 2 in which the crankshaft drive mechanism 10 is located on the right side of the frame 30, and the connecting rod drive mechanism 20 is located on the left side of the frame 30. Of course, the installation positions of the crankshaft drive mechanism 10 and the connecting rod drive mechanism 20 can also be interchanged, and this application does not make specific limitations.

[0037] The crankshaft drive mechanism 10 is rotatably connected to one end of the frame 30. In this way, the crankshaft drive mechanism 10 can drive one end of the frame 30 to rotate relative to the frame, thereby driving the kneading mechanism 40 to move, and further causing one end of the kneading mechanism 40 to move downward or upward. Similarly, the connecting rod drive mechanism 20 is connected to the other end of the frame 30. In this way, the connecting rod drive mechanism 20 can drive the other end of the frame 30 to move, thereby driving the kneading mechanism 40 to move, and further causing the other end of the kneading mechanism 40 to move upward or downward. In this way, multi-directional adjustment of the kneading mechanism 40 located on the frame 30 can be realized, and further, the kneading component of the massage mechanism can apply variable radial massage forces to the user, thereby realizing a rich massage experience.

[0038] In summary, the massage mechanism provided by the present application includes a crankshaft drive mechanism 10, a connecting rod drive mechanism 20, a frame 30, and a kneading mechanism 40 provided on the frame 30; the crankshaft drive mechanism 10 and the connecting rod drive mechanism 20 are respectively provided on the frame of the massage mechanism, and the opposite sides of the frame 30 are respectively rotatably connected to the crankshaft drive mechanism 10 and the connecting rod drive mechanism 20. The crankshaft drive mechanism 10 is used to drive one end of the frame 30 to move relative to the frame, and the connecting rod drive mechanism 20 is used to drive the other end of the frame 30 to move relative to the frame. In the present application, the kneading mechanism 40 is provided on the frame 30, and the crankshaft drive mechanism 10 and the connecting rod drive mechanism 20 are respectively provided on the opposite sides of the frame 30. In this way, the present application can drive the frame 30 rotatably connected thereto by the crankshaft drive mechanism 10 to swing up and down to adjust the height of one end of the frame 30, and drive the other end of the frame 30 rotatably connected thereto by the connecting rod drive mechanism 20 to swing up and down to adjust the height of the other end of the frame 30, so that the kneading mechanism 40 can apply variable radial massage forces to the user, thereby realizing richer and more comfortable massage techniques and improving the user experience.

[0039] Please refer to Figure 2 and Figure 3 , optionally, the above-mentioned crankshaft drive mechanism 10 includes a positioning block 11, a first crankshaft 12, and a first drive source 13; the first drive source 13 includes a first gearbox 131 provided on the frame. The first gearbox 131 and the positioning block 11 are respectively provided on the frame. One end of the first crankshaft 12 is fixedly connected to the first gear 132 in the first gearbox 131, and the other end passes through and is rotatably connected in the positioning block 11; one side of the frame 30 away from the connecting rod drive mechanism 20 is hinged to the middle crankshaft section of the first crankshaft 12.

[0040] It should be noted that the first drive source 13 can provide support and power for the first crankshaft 12. Specifically, the first drive source 13 includes a first gearbox 131, and the first gear 132 in the first gearbox 131 is fixedly connected to one end of the first crankshaft 12, so that the rotation of the first gear 132 can drive the first crankshaft 12 to rotate. The first gear 132 can both provide power for the first crankshaft 12 and provide support for the first crankshaft 12. The other end of the first crankshaft 12 passes through the positioning block 11, so that the positioning block 11 can provide a supporting force for the other end of the first crankshaft 12. It should be understood that corresponding holes are provided in the positioning block 11 to facilitate the rotational connection with the end of the first crankshaft 12.

[0041] Among them, the present application does not limit the shape of the positioning block 11, and those skilled in the art can determine it by themselves.

[0042] Also, as Figure 2As shown, the first crankshaft 12 includes two first shaft sections and a second shaft section (i.e., the middle crankshaft section mentioned above), wherein the second shaft section is connected between the two first shaft sections, the two first shaft sections are collinear, the first shaft section and the second shaft section are parallel and not collinear, and one end of the frame 30 away from the connecting rod drive mechanism 20 is hinged on the second shaft section.

[0043] Optionally, the crankshaft drive mechanism 10 also includes a first Hall sensor 14 provided on the first crankshaft 12 and a first detection signal board 15 electrically connected to the first Hall sensor 14 , and the first detection signal board 15 is used to detect the rotation angle of the first crankshaft 12 based on the electrical signal obtained from the first Hall sensor 14 .

[0044] In the present application, the first Hall sensor 14 is disposed on the first crankshaft 12, so that the first detection signal board 15 can obtain the rotation angle of the first crankshaft 12 by analyzing the electrical signal of the first Hall sensor 14. Since the working principles of the first Hall sensor 14 and the first detection signal board 15 are well known to those skilled in the art, the present application will not elaborate on them.

[0045] like Figure 2 and Figure 3 Optionally, the crankshaft driving mechanism 10 further includes a first limiting plate 16 disposed on the frame. The first limiting plate 16 is located on a side of the crankshaft driving mechanism 10 away from the frame 30 . The first limiting plate 16 is used to limit the rotation of the frame 30 .

[0046] The present application sets the first limit plate 16 on the frame, and sets the first limit plate 16 on the side of the crankshaft drive mechanism 10 away from the frame 30, so that when the first drive source 13 drives the first crankshaft 12 of the crankshaft drive mechanism 10 to rotate, the first limit plate 16 can limit the swing of the frame 30. The first limit plate 16 of the present application allows the frame 30 to swing on the side of the first limit plate 16 close to the crankshaft drive mechanism 10, and can limit the swing range of the frame 30 to within 180°.

[0047] It should be noted that the shape of the first limit plate 16 is not limited in this application, as long as the swing of the frame 30 can be limited to the side of the first limit plate 16 close to the crankshaft drive mechanism 10 and the swing range of the frame 30 can be limited within 180°.

[0048] In order to facilitate the articulation of the frame 30 and the first crankshaft 12, optionally, the crankshaft drive mechanism 10 also includes two spaced apart adapter plates 17 fixedly connected to the frame 30, and each adapter plate 17 is respectively connected to a corresponding rotating shaft sleeve 18; the two adapter plates 17 are located on one side of the frame 30 close to the crankshaft drive mechanism 10, and the middle crankshaft section of the first crankshaft 12 is inserted into the two rotating shaft sleeves 18 and is rotatably connected to the two rotating shaft sleeves 18.

[0049] In this embodiment, the adapter plate 17 is in a Z shape, and one end of the adapter plate 17 is fixedly connected to the vehicle frame 30, and the other end is fixedly connected to the rotating shaft sleeve 18. A through hole is provided in the rotating shaft sleeve 18 to facilitate its hinged connection with the first crankshaft 12.

[0050] This application is provided with two adapter plates 17 and rotating shaft sleeves 18 corresponding to the adapter plates 17 one by one, and the adapter plates 17 are arranged at intervals. In this way, the hinged relationship between the vehicle frame 30 and the first crankshaft 12 can be made more stable and reliable, and the connection reliability of the massage mechanism can be improved.

[0051] Hereinafter, this embodiment will continue to elaborate on the specific structure of the link drive mechanism 20 in detail. Optionally, the link drive mechanism 20 includes a drive gearbox 21, a traveling drive shaft 22, a second drive source 23, a drive link 24, and a swing bracket 25; the drive gearbox 21 and the second drive source 23 are respectively arranged on the frame. One end of the traveling drive shaft 22 is rotatably connected to the drive gearbox 21, and the other end is fixedly connected to the second drive source 23. The second drive source 23 can provide power for the traveling drive shaft 22 to rotate relative to the drive gearbox 21; one end of the drive link 24 is fixedly connected to the side of the traveling drive shaft 22 close to the vehicle frame 30, and the other end is hinged to one end of the swing bracket 25. The other end of the swing bracket 25 is hinged to the side of the vehicle frame 30 facing away from the crankshaft drive mechanism 10.

[0052] Among them, the drive gearbox 21 and the second drive source 23 are respectively arranged on the frame, and one end of the traveling drive shaft 22 is rotatably connected to the drive gearbox 21, and the other end is fixedly connected to the second drive source 23. In this way, the second drive source 23 can provide driving force for the traveling drive shaft 22, and then drive the traveling drive shaft 22 to rotate relative to the drive gearbox 21. Specifically, in this embodiment, the second drive source 23 includes a fixed gear 231, and the fixed gear 231 is fixedly connected to the traveling gear 26. In this way, the traveling gear 26 can be driven to rotate by the fixed gear 231 of the second drive source 23.

[0053] In this embodiment, one end of the drive link 24 is fixedly connected to the side of the traveling drive shaft 22 close to the vehicle frame 30. Of course, in other embodiments, the drive link 24 and the traveling drive shaft 22 can also be integrally formed parts, and in this way, the structural stability is better.

[0054] One end of the swing bracket 25 is hinged to one end of the drive link 24 close to the vehicle frame 30, and the other end is hinged to the vehicle frame 30. In this way, when the traveling drive shaft 22 rotates, the swing bracket 25 can be driven to rotate, and then the vehicle frame 30 can be driven to rotate. In this way, the relative height of the kneading mechanism 40 provided on the vehicle frame 30 can be adjusted.

[0055] Please refer to Figure 4, in this embodiment, the first crankshaft 12, the frame 30, the drive link 24, and the swing bracket 25 can form a four-bar linkage mechanism. The hinge points of the frame 30 and the first crankshaft 12 and the hinge points of the swing bracket 25 and the frame 30 have different swinging directions, and the swinging directions of the two hinge points can be individually force-controlled.

[0056] Optionally, two traveling gears 26 are also sleeved on opposite ends of the traveling drive shaft 22. The two traveling gears 26 are respectively located on opposite sides of the drive link 24, and the traveling gears 26 are used to cooperate with the racks on the massage backrest of the massage chair.

[0057] It should be noted that the first gearbox 131 in the foregoing is used to drive the above-mentioned traveling gears 26 to rotate, so that the traveling gears 26 cooperate with the racks on the massage backrest of the massage chair to move.

[0058] Similar to the crankshaft drive mechanism 10, optionally, the link drive mechanism 20 further includes a second Hall sensor 27 disposed on the drive link 24 and a second detection signal board 28 electrically connected to the second Hall sensor 27. The second detection signal board 28 is used to detect the rotation angle of the drive link 24 according to the electrical signal obtained by the second Hall sensor 27.

[0059] Among them, the second Hall sensor 27 and the second detection signal board 28 have the same principle as the first Hall sensor 14 and the first detection signal board 15. For the relevant descriptions in the first Hall sensor 14 and the first detection signal board 15, reference can be made to the foregoing, and the present application will not repeat the description.

[0060] In order to limit the rotation of the side of the frame 30 close to the link drive mechanism 20, so that the frame 30 rotates between the link drive mechanism 20 and the crankshaft drive mechanism 10, and its rotation angle is limited within 90°. Optionally, in this embodiment, the link drive mechanism 20 further includes a second limit plate 29 disposed on the machine frame. The second limit plate 29 is located on the side of the traveling drive shaft 22 away from the frame 30, and the second limit plate 29 is used to limit the rotation of the frame 30.

[0061] It should be noted that the present application does not limit the specific structure of the second limit plate 29, as long as the rotation of the frame 30 can be limited between the link drive mechanism 20 and the crankshaft drive mechanism 10, and the rotation angle is within 90°.

[0062] In the following embodiments, the specific structure of the kneading mechanism 40 will be described in detail. Optionally, the kneading mechanism 40 further includes two fixed supports 41 provided on the vehicle frame 30, a kneading shaft 42 with both ends rotatably connected to the two fixed supports 41 respectively, two eccentric blocks 43 sleeved on the opposite ends of the kneading shaft 42 and fixed to the kneading shaft 42, two kneading crank arms 44 sleeved on the outer circumferences of the two eccentric blocks 43 respectively, a knocking seat 451 provided on the vehicle frame 30, an eccentric shaft 46 passing through a through hole of the knocking seat 451, two bearing seats 471 provided at both ends of the eccentric shaft 46 and fixed to the eccentric shaft 46, and a spherical connecting rod 472 connecting the bearing seat 471 and the kneading crank arm 44; wherein, the spherical connecting rod 472 is fixedly connected to the bearing seat 471 and hinged to the kneading crank arm 44; the eccentric shaft 46 is driven to rotate, and the eccentric shaft 46 can drive the two kneading crank arms 44 to rotate through the spherical connecting rod 472.

[0063] Among them, the two fixed supports 41 are spaced apart on the vehicle frame 30 and are used to provide a supporting force for the kneading shaft 42 and the kneading crank arm 44. It should be understood that the specific shape of the fixed support 41 is not limited in this application.

[0064] As Figure 2 and Figure 3 shown, the kneading crank arm 44 includes a crank arm and two massage balls 441 respectively provided at the opposite ends of the crank arm. The massage ball 441 is used to act on the user's back or shoulder to perform a massage treatment on the user.

[0065] In addition, this application also provides a gear box 48 fixed to the vehicle frame 30. The gear box 48 includes a second driving motor. As Figure 2 shown, the gear box 48 is provided between the two kneading crank arms 44 and is used to provide power for the kneading shaft 42 through the second driving motor, so that the two eccentric blocks 43 drive the two kneading crank arms 44 to swing.

[0066] This application also provides a knocking seat 451 between the two kneading crank arms 44. An eccentric shaft 46 is passed through the knocking seat 451. Both ends of the eccentric shaft 46 are connected with bearing seats 471. A spherical connecting rod 472 is connected to the bearing seat 471, and the other end of the spherical connecting rod 472 is connected to the kneading crank arm 44. In this way, by controlling the rotation of the eccentric shaft 46, the two kneading crank arms 44 can be driven to swing.

[0067] Optionally, the kneading mechanism 40 further includes a gland 452 buckled on the knocking seat 451. The knocking seat 451 and the gland 452 cooperate with each other to form a receiving cavity, and the eccentric shaft 46 is located in the receiving cavity. The setting of the gland 452 can protect the eccentric shaft 46 and facilitate the formation of a space for accommodating the eccentric shaft 46.
