Description

Technical Field

[0001] This application relates to the field of massage device technology, and more specifically, to a massage mechanism and a massage chair. Background Technology

[0002] Massage chairs are a common type of health care device. The core functional component of a massage chair is the massage mechanism, which simulates the effect of a manual massage. Current massage mechanisms include a rocker arm, with a massage roller mounted at both ends. During a massage, the massage mechanism moves back and forth along the user's buttocks and back to massage various areas of the user's back.

[0003] Existing massage mechanisms typically have only one massage roller at the front and back of the rocker arm, resulting in a small massage area. Having only one roller at each end reduces the contact area with the user's back, making it prone to causing pressure pain and leading to a poor user experience for some users.

[0004] Therefore, how to increase the massage area and improve the user experience is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a massage mechanism to increase the massage area and improve the user experience;

[0016] In one possible implementation, the rocker arm is indirectly hinged to the mechanism base plate via a rocker arm mounting assembly;

[0017] The rocker arm mounting assembly includes a rocker arm mounting base and a rocker arm support shaft. The rocker arm support shaft is rotatably mounted on the core substrate. The rocker arm mounting base is connected to the rocker arm support shaft and can rotate along the axis of the rocker arm support shaft. The rocker arm shaft and the rocker arm support shaft are spaced apart and arranged parallel to each other.

[0018] In one possible implementation, a striking drive device is also included to drive the rocker arm mount to reciprocate about the rocker arm support axis.

[0043] This application discloses a massage mechanism to increase the massage area and improve the user experience;

[0044] This application also discloses a massage chair having the above-described massage mechanism.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] like Figures 1-3 As shown in the figure, this application discloses a massage mechanism, which includes a mechanism base plate 100 and a rocker arm assembly 400.

[0047] The core base plate 100 provides a direct or indirect mounting base for other components of the massage mechanism, enabling the core base plate 100 to be installed in the corresponding position on the massage chair. The core base plate 100 is equipped with an active walking mechanism 200 and a driven walking mechanism 600. The active walking mechanism 200 is driven by a motor and includes a drive shaft with an active walking wheel and a drive gear. The driven walking mechanism 600 includes a driven shaft with a driven walking wheel.

[0048] When the drive shaft rotates, it drives the drive wheels and the drive gear to rotate. The drive gear meshes with the massage chair's drive rack, and both the drive wheels and driven wheels engage with the massage chair's running track. When the drive gear rotates, it moves along the drive rack because it meshes with it. Since both the drive wheels and driven wheels engage with the massage chair's running track, they move along the massage mechanism and along the drive rack.

[0049] The rocker arm assembly 400 includes a rocker arm 401 directly or indirectly hinged to the mechanism base plate 100, and a first massage roller device 402 and a second massage roller device 403 disposed on the rocker arm 401. Since the rocker arm 401 can swing relative to the mechanism base plate 100, it can adjust its posture according to the user's back to ensure the fit between the first massage roller device 402 and the second massage roller device 403 and the user's back. Typically, there are two rocker arm assemblies 400, and the axes of swing of the two rocker arm assemblies 400 can be collinear.

[0050] At least one of the first massage roller device 402 and the second massage roller device 403 includes at least two massage rollers that are spaced apart on the axis and arranged in parallel. In this embodiment, more than two massage rollers may be provided on only one of the first massage roller device 402 and the second massage roller device 403, or more than two massage rollers may be provided on only one of them.

[0051] The massage mechanism disclosed in this application, through an active walking mechanism 200 and a driven walking mechanism 600, enables the massage mechanism to reciprocate along corresponding tracks to massage different positions on the user's back. Its rocker arm 401 is equipped with a first massage roller device 402 and a second massage roller device 403. At least one of the first massage roller device 402 and the second massage roller device 403 includes at least two massage rollers arranged parallel to each other with their axes spaced apart. This arrangement increases the contact area between the massage rollers and the user's body, avoiding pressure pain caused by a small contact area and improving massage comfort.

[0052] In a specific embodiment of this application, the second massage wheel device 403 may include an adaptive adjustment plate 4031 and at least two massage wheels 4032 disposed on the adaptive adjustment plate 4031. The adaptive adjustment plate 4031 is rotatably connected to the rocker arm 401, and the rotation axis of the adaptive adjustment plate 4031 is parallel to the rotation axis of the massage wheels 4032 on the adaptive adjustment plate 4031.

[0053] like Figure 4As shown, when the massage mechanism moves to the buttocks and waist of the human body, the rocker arm 401 rotates and adjusts around its rotation center, so that the massage wheels of the first massage wheel device 402 are adapted to the corresponding position of the waist. The adaptive adjustment plate 4031 of the second massage wheel device 403 rotates around its rotation axis, so that the multiple massage wheels 4032 on the adaptive adjustment plate 4031 are adapted to the curvature of the buttocks.

[0054] like Figure 5 As shown, when the massage mechanism moves to the waist and back of the human body, the rocker arm 401 rotates and adjusts around its rotation center, so that the massage wheels of the first massage wheel device 402 are adapted to the corresponding position on the back, and the adaptive adjustment plate 4031 of the second massage wheel device 403 rotates around its rotation axis, so that the multiple massage wheels 4032 on the adaptive adjustment plate 4031 are adapted to the curvature of the waist.

[0055] like Figure 6 As shown, when the massage mechanism moves to the back and neck of the human body, the rocker arm 401 rotates and adjusts around its rotation center, so that the massage rollers of the first massage roller device 402 are adapted to the corresponding position of the neck, and the adaptive adjustment plate 4031 of the second massage roller device 403 rotates around its rotation axis, so that the multiple massage rollers 4032 on the adaptive adjustment plate 4031 are adapted to the curvature of the back.

[0056] Furthermore, such as Figure 4 As shown, the adaptive adjustment plate 4031 is provided with two massage rollers 4032, and the two massage rollers 4032 are symmetrically arranged along the rotation axis of the adaptive adjustment plate 4031. In this embodiment, providing two massage rollers 4032 on the adaptive adjustment plate 4031 can prevent the adaptive adjustment plate 4031 from being too long due to an excessive number of massage rollers 4032, thus failing to adapt to the curve of the lower back. The symmetrical arrangement of the two massage rollers 4032 along the rotation axis of the adaptive adjustment plate 4031 ensures that the two massage rollers 4032 have the same rotation radius, resulting in a uniform and relatively large rotation radius within the limited length of the adaptive adjustment plate 4031.

[0057] In one specific embodiment of this application, a massage wheel is provided on the first massage wheel device 402, which is located above the second massage wheel device 403. It should be noted that the neck is located above the back, and the back is located above the buttocks; that is, the first massage wheel device 402 is located above the second massage wheel device 403, meaning the massage area of ​​the first massage wheel device 402 is located above the massage area of ​​the second massage wheel device 403.

[0058] The diameter of the massage roller in the first massage roller device 402 is larger than the diameter of the massage roller in the second massage roller device 403. Since the first massage roller device 402 has only one massage roller, while the second massage roller device 403 has two or more massage rollers, the diameter of the massage roller in the first massage roller device 402 can be designed to be larger to increase its massage area. Conversely, since the second massage roller device 403 has a larger number of massage rollers, the massage area can be accumulated, so the diameter of the massage rollers in the second massage roller device 403 can be designed to be smaller. Furthermore, designing the diameter of the massage rollers in the second massage roller device 403 to be smaller also facilitates its spatial arrangement.

[0059] It should be noted that the diameter of the massage roller of the first massage roller device 402 can also be designed to be equal to the diameter of the massage roller of the second massage roller device 403. This embodiment does not limit the relationship between the diameters of the massage rollers of the first massage roller device 402 and the second massage roller device 403.

[0060] like Figure 1 and Figure 2 As shown, in a specific embodiment of this application, the rocker arm 401 is indirectly hinged to the movement base plate 100 via the rocker arm mounting bracket assembly 300. Specifically, the rocker arm mounting bracket assembly 300 includes a rocker arm mounting bracket 301 and a rocker arm support shaft 302.

[0061] The rocker arm support shaft 302 is mounted on the mechanism base plate 100, and the rocker arm mounting base 301 is connected to the rocker arm support shaft 302 and can rotate along the axis of the rocker arm support shaft 302. Specifically, the rocker arm support shaft 302 can be rotatably mounted on the mechanism base plate 100, and the rocker arm mounting base 301 can be fixed to the rocker arm support shaft 302, thus enabling the rocker arm mounting base 301 to rotate along the axis of the rocker arm support shaft 302; alternatively, the rocker arm support shaft 302 can be fixed to the mechanism base plate 100, and the rocker arm mounting base 301 can be rotatably mounted on the rocker arm support shaft 302, thus also enabling the rocker arm mounting base 301 to rotate along the axis of the rocker arm support shaft 302.

[0062] The rocker arm 401 is hinged to the rocker arm mounting base 301 via a rocker arm shaft 404, and the rocker arm shaft 404 and the rocker arm support shaft 302 are spaced apart and arranged parallel to each other. Figure 4 As shown, the rocker arm 401 has a rocker arm shaft hinge hole 4011 that mates with the rocker arm shaft 404. In this embodiment, the rocker arm 401 is hinged to the rocker arm mounting base 301 via the rocker arm shaft 404, allowing the rocker arm 401 to rotate around the axis of the rocker arm shaft 404. Furthermore, since the rocker arm mounting base 301 can also rotate around the axis of the rocker arm support shaft 302, the swing range and degree of freedom of the rocker arm 401 are expanded, and the adaptability of the rocker arm assembly 400 to the user's back curve is improved.

[0063] To enhance the massage effect of the massage mechanism, in one specific embodiment of this application, the massage mechanism may further include a tapping drive device 500 that drives the rocker arm mounting base 301 to reciprocate around the rocker arm support shaft 302. In this embodiment, by driving the rocker arm mounting base 301 to reciprocate around the rocker arm support shaft 302 through the tapping drive device 500, the rocker arm assembly 400 can be made to vibrate reciprocally, so that the first massage roller device 402 located at the second massage roller device 403 generates a tapping force acting on the user's back, thereby improving the massage effect.

[0064] Specifically, the striking drive device 500 may include a drive assembly, an eccentric sleeve 505, and a ball-head push-pull rod 506. The eccentric sleeve 505 is rotatably fitted onto the eccentric shaft of the drive assembly. One end of the ball-head push-pull rod 506 is provided with a ball head, and the other end is hinged to the eccentric sleeve 505. A ball head sleeve is provided on the rocker arm mounting base 301, and the ball head is spherically hinged to the ball head sleeve.

[0065] When the drive device drives the eccentric shaft to perform eccentric rotation, the eccentric sleeve 505 rotates with the eccentric shaft, and the eccentric sleeve 505 is connected to the rocker arm mounting base 301 through the ball head push-pull rod 506. This restricts the circumferential rotation of the eccentric sleeve 505, which can only be moved by the eccentric shaft to produce spatial movement. This, in turn, drives the ball head push-pull rod 506, which in turn pushes the rocker arm mounting base 301 to swing back and forth, generating a push-pull rocker arm assembly 400, which in turn produces a reciprocating cyclical striking effect.

[0066] Furthermore, the drive assembly can be a belt drive mechanism. Specifically, the drive assembly includes a drive motor 501 and a driven pulley shaft 504. The output shaft of the drive motor 501 is equipped with a drive pulley 502, enabling the drive motor 501 to drive the drive pulley 502 to rotate.

[0067] The driven pulley shaft 504 is supported on the movement base plate 100. A driven pulley is provided on the driven pulley shaft 504, and the driven pulley can rotate around the axis of the driven pulley shaft 504. Specifically, the driven pulley shaft 504 can be rotatably supported on the movement base plate 100, and the driven pulley can be fixed on the driven pulley shaft 504. This arrangement allows the driven pulley to rotate around the axis of the driven pulley shaft 504. Alternatively, the driven pulley shaft 504 can be fixed on the movement base plate 100, and the driven pulley can be rotatably mounted on the driven pulley shaft 504. This arrangement also allows the driven pulley to rotate around the axis of the driven pulley shaft 504.

[0068] The driving pulley 502 and the driven pulley are connected by a transmission belt 503. The driven pulley is eccentrically mounted with an eccentric shaft. The power output from the drive motor 501 is transmitted to the driven pulley through the belt drive mechanism. When the driven pulley rotates, it drives the eccentric shaft to rotate around the axis of the driven pulley, which in turn causes the eccentric sleeve 505 to reciprocate, ultimately achieving the striking effect of the rocker arm assembly 400.

[0069] This application also discloses a massage chair, which includes the massage mechanism disclosed in the above embodiments. Because it has the aforementioned massage mechanism, it possesses all the technical effects of the massage mechanism described above, and will not be repeated here.
