Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Reference Figure 1 and Figure 2 As shown in the embodiment of this application, a massage chair includes a seat 100, a leg rest 101, and a massage mechanism. The leg rest 101 is rotatably connected to the seat 100 via a rotating assembly 102. The massage mechanism includes a rotating shaft 103 and two sets of knee-back massage assemblies 104 mounted on the rotating shaft 103. The central axis of the rotating shaft 103 is parallel to the rotation axis of the rotating assembly 102. An upper swing massage assembly 105 is mounted on the seat 100, and a lower swing massage assembly 106 is mounted on the leg rest 101. An eccentric wheel 107 is mounted on the rotating shaft 103, and the eccentric wheel 107 is connected to the upper swing massage assembly 105 and the lower swing massage assembly 106 via two rockers 108. The rotating shaft 103 drives the two sets of knee-back massage assemblies 104 to rotate and massage the user's knees, and the rockers 108 drive the upper swing massage assembly 105 and the lower swing massage assembly 106 to scrape and massage the user's thighs and calves, respectively.

[0032] It should be noted that, in this embodiment, the rotating shaft 103 is provided with two back-of-the-knee massage components 104. Each back-of-the-knee massage component 104 has a cylindrical structure, and the rotating shaft 103 can pass through the center of the cylindrical structure, allowing the rotating shaft 103 to drive the back-of-the-knee massage components 104 to rotate. Since the back of the knee forms a deep depression when the knee is bent, compared to a scraping massage structure, the cylindrical structure can accurately enter the back-of-the-knee depression and provide reliable support. Furthermore, because the cylindrical structure has an arc-shaped surface, the back-of-the-knee massage components 104 can have a larger contact area with the back of the knee through this arc-shaped surface, thereby achieving a better massage effect.

[0033] It should be noted that the central axis of the rotating shaft 103 is parallel to the rotation axis of the rotating assembly 102 and the distance between them is small. This ensures that the rotation center of the back knee massage assembly 104 is close to the rotation center of the calf support 101, that is, when the user sits on the seat, the back knee massage assembly 104 can accurately correspond to the back of the knee.

[0034] Preferably, the central axis of the rotating shaft 103 is aligned with the rotation axis of the rotating assembly 102. Specifically, a single rotating shaft 103 can be used to pass through the seat plate 100, the calf support plate 101, and the two knee-back massage assemblies 104. The middle of the rotating shaft 103 is driven to rotate the two knee-back massage assemblies 104 to perform massage. Both ends of the rotating shaft 103 are connected to the seat plate 100 and the calf support plate 101 through bearings to prevent the calf support plate 101 from rotating due to rotation. This embodiment of the application ensures that when the user sits on the seat plate 100, with the thigh abutting against the upper swing massage assembly 105 and the lower swing massage assembly 106 abutting against the calf, the back of the knee can accurately abut against the knee-back massage assembly 104, ensuring that the back of the knee receives effective massage.

[0035] This application provides a massage chair, including a seat 100, a leg rest 101, and a massage mechanism. The leg rest 101 is rotatably connected to the seat 100 via a rotating assembly 102. The massage mechanism includes a rotating shaft 103 and two sets of knee-back massage components 104 mounted on the rotating shaft 103. The central axis of the rotating shaft 103 is parallel to the rotation axis of the rotating assembly 102. An upper swing massage component 105 is mounted on the seat 100, and a lower swing massage component 106 is mounted on the leg rest 101. The rotating shaft 103 passes through an eccentric wheel 107, which is connected to the upper swing massage component 105 and the lower swing massage component 106 via two rockers 108. When driven, the rotating shaft 103 can rotate and massage the user's knees with the two sets of knee-back massage components 104, and the rockers 108 can drive the upper swing massage component 105 and the lower swing massage component 106 to perform scraping massage on the user's thighs and calves, respectively. Therefore, the embodiments of this application can accurately massage the popliteal fossa area, achieving simultaneous massage of the thigh, popliteal fossa, and calf, allowing users to obtain a better massage experience.

[0036] Reference Figure 2 and Figure 4 As shown, in one optional implementation, the back-of-the-knee massage assembly 104 includes a first roller 109 and a second roller 110; the first roller 109 is provided with first massage protrusions 111 of different heights at intervals along the circumference, and the second roller 110 is provided with second massage protrusions 112 of different heights at intervals along the circumference; the first massage protrusions 111 and the second massage protrusions 112 are alternately distributed along the circumference.

[0037] It should be noted that the knee-back massage assembly 104 in this embodiment includes a first roller 109 and a second roller 110, and first massage protrusions 111 and second massage protrusions 112 are respectively provided on the first roller 109 and the second roller 110 at intervals along the circumference. Each of the first massage protrusions 111 and the second massage protrusions 112 includes multiple protrusion structures of different heights. During the rotation of the first roller 109 and the second roller 110, the protrusion structures of different heights provide different sensations of massage to the knee-back area. Furthermore, in this embodiment, the first massage protrusions 111 and the second massage protrusions 112 are alternately distributed along the circumference. This alternating distribution enhances the unevenness of the same massage contact surface, thereby further effectively improving the massage effect of the first roller 109 and the second roller 110 during rotational massage.

[0038] Reference Figure 2 and Figure 4As shown, as an optional implementation, there are two eccentric wheels 107, which are respectively disposed between the first roller 109 and the second roller 110 of the two knee massage components 104; the central axis of the eccentric wheel 107 is parallel to the central axis of the rotating shaft 103 and is spaced apart.

[0039] In this embodiment, the eccentric wheel 107 is clamped between the first roller 109 and the second roller 110. When the end of the rocker arm 108 is sleeved onto the eccentric wheel 107, the rollers on both sides can clamp the rocker arm 108, ensuring a reliable rotatable connection between the rocker arm 108 and the eccentric wheel 107 and preventing the rocker arm 108 from disengaging from the eccentric wheel 107. The eccentric wheel 107 can be integrally formed on the first roller 109 or integrally formed on the second roller 110. Alternatively, those skilled in the art can fix the eccentric wheel 107 between the first roller 109 and the second roller 110 using bolts or snap-fit ​​devices as needed.

[0040] Reference Figure 2 As shown, in one optional implementation, a connecting gear 113 is provided on the rotating shaft 103, and a drive motor 114 is installed on the seat plate 100 or the lower leg support plate 101. The power output end of the drive motor 114 meshes with the connecting gear 113 through a speed change gear assembly 115, and the drive motor 114 drives the rotating shaft 103 to rotate through the speed change gear assembly 115.

[0041] In this embodiment, a connecting gear 113 is installed on the rotating shaft 103, and the drive motor 114 meshes with the connecting gear 113 through the speed change gear assembly 115 to achieve drive control of the rotating shaft 103.

[0042] Reference Figure 2 and Figure 4 as well as Figure 5 As shown, in one optional embodiment, the upper swing massage assembly 105 includes an upper swing frame 116 rotatably mounted on the seat plate 100, and an upper massage roller 117 mounted on one side of the upper swing frame 116 and capable of abutting against the user's thigh; an upper connecting shaft passing through a rocker arm 108 is provided on the other side of the upper swing frame 116; the central rotation axis of the upper swing frame 116 and the upper connecting shaft are both parallel to the rotating shaft 103. The lower swing massage assembly 106 includes a lower swing frame 118 rotatably mounted on the calf support plate 101, and a lower massage roller 119 mounted on one side of the lower swing frame 118 and capable of abutting against the user's calf; a lower connecting shaft passing through a rocker arm 108 is provided on the other side of the lower swing frame 118; the central rotation axis of the lower swing frame 118 and the lower connecting shaft are both parallel to the rotating shaft 103.

[0043] It should be noted that in this embodiment of the application, two rockers 108 drive the upper swing frame 116 and the lower swing frame 118 to swing respectively. The swing of the upper swing frame 116 can drive the upper massage roller 117 to perform rolling massage on the thigh, and the swing of the lower swing frame 118 can drive the lower massage roller 119 to perform rolling massage on the calf. The rollers can achieve a better massage effect.

[0044] Reference Figure 1 and Figure 3 As shown, in one optional implementation, the seat plate 100 is provided with a first opening 120, and the upper massage roller 117 is located in the first opening 120; the calf support plate 101 is provided with a second opening 121, and the lower massage roller 119 is located in the second opening 121.

[0045] Furthermore, in this embodiment, a first opening 120 is provided on the seat 100, allowing a portion of the upper massage roller 117 to be positioned inside the first opening 120. This prevents the upper massage roller 117 from protruding too far from the seat 100, thus avoiding discomfort for the user. In other words, the first opening 120 allows the upper massage roller 117 to be recessed, reducing the impact of the upper swing massage component 105 on the seat 100's surface, ensuring comfort while providing massage to the thighs. In this embodiment, a second opening 121 is provided on the calf support 101, allowing a portion of the lower massage roller 119 to be positioned inside the second opening 121. This prevents the lower massage roller 119 from protruding too far from the calf support 101, thus avoiding discomfort for the user. In other words, the lower massage roller 119 is designed to sink down through the second opening 121, which reduces the impact of the lower swing massage component 106 on the calf support plate 101 when supporting the calf, ensuring that the calf support plate 101 provides support comfort while massaging the calf.

[0046] Referring to Figure 6, an embodiment of this application provides a car massage seat, including the massage chair described above; armrests 122 are provided on the left and right sides of the seat 100 of the massage chair, and a backrest 123 is rotatably provided on the side of the seat 100 away from the calf support 101; the seat 100 is connected to the vehicle floor through a bottom support 124.

[0047] The car massage seat provided in this application embodiment has a compact structure and can replace the traditional seats in the vehicle, allowing vehicle occupants to perform rolling massage on the back of their knees inside the vehicle, achieving simultaneous massage of the thighs, back of the knees and calves, ensuring that vehicle occupants can obtain a better massage experience inside the vehicle.

[0048] Reference Figure 6As shown, in one optional implementation, a telescopic component 125 is provided on the bottom support 124, and the telescopic end of the telescopic component 125 is hinged to the calf support plate 101; the telescopic component 125 can push the calf support plate 101 to rotate around the seat plate 100. In this embodiment of the application, the rotation angle of the calf support plate 101 can be adjusted by the provision of the telescopic component 125, wherein the telescopic component 125 can be an electric telescopic rod.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
