Description

Technical Field

[0001] This application relates to the field of massage equipment technology, and more specifically, to a segmented guide rail structure, a massage chair frame, and a massage chair. Background Technology

[0002] Existing massage chairs consist of a backrest frame and a seat frame, with massage mechanisms installed on both. The massage mechanism on the backrest frame massages the user's back, while the massage mechanism on the seat frame massages the user's thighs.

[0003] Because the massage mechanisms on the backrest frame and the seat frame are located on the backrest rail and seat rail respectively, a certain gap is usually set at the ends of the seat rail and backrest rail when they approach each other to avoid collision and interference. This creates a large gap between the ends of the seat rail and backrest rail. While this gap prevents interference when the two massage mechanisms are close together, it also interrupts the movement of the massage area, creating gaps in the massage zone. The massage mechanisms cannot move back and forth on the backrest rail and seat rail, thus preventing a continuous and complete massage of the seat and back. Summary of the Invention

[0004] The purpose of this application is to provide a segmented guide rail structure, a massage chair frame, and a massage chair. The segmented guide rail structure enables the backrest guide rail and the seat guide rail to be connected to form a composite track, allowing the massage mechanism to move back and forth on the backrest guide rail and the seat guide rail, thereby achieving a continuous and complete massage of the user's seat and back.

Detailed Implementation

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] In existing technologies, gaps are typically provided near the backrest guide rail 101 and the seat guide rail 100 to prevent interference from the massage mechanism. This causes an interruption between the backrest guide rail 101 and the seat guide rail 100, resulting in a gap in the massage area. The massage mechanism cannot move back and forth on the backrest guide rail 101 and the seat guide rail 100, thus preventing continuous and complete massage of the seat and back.

[0035] Reference Figure 1 and Figure 2 As shown, in a first aspect, embodiments of this application provide a segmented guide rail structure for a massage chair, including a seat guide rail 100 and a backrest guide rail 101. The end of the seat guide rail 100 is provided with a first connecting end 102, and the end of the backrest guide rail 101 is provided with a second connecting end 103. A hinge assembly 104 is provided at the connection between the first connecting end 102 and the second connecting end 103. The seat guide rail 100 and the backrest guide rail 101 are connected to form a composite guide rail 105. The massage mechanism of the massage chair is driven to move on the track of the composite guide rail 105.

[0036] It should be noted that, in this embodiment of the application, a hinge assembly 104 is provided at the first connecting end 102 and the second connecting end 103. The seat guide rail 100 and the backrest guide rail 101 are connected by the hinge assembly 104, allowing the formed composite guide rail 105 to rotate. This enables the massage mechanism to reciprocate at different angles. For example, the angle between the seat guide rail 100 and the backrest guide rail 101 is 90°, which ensures that the massage mechanism can reciprocate on the composite guide rail 105 in a seated massage position. For example, the angle between the seat guide rail 100 and the backrest guide rail 101 is 150°, which ensures that the massage mechanism can reciprocate on the composite guide rail 105 in a reclining massage position.

[0037] This application provides a segmented guide rail structure for a massage chair, including a seat guide rail 100 and a backrest guide rail 101. The application provides a first connecting end 102 at the end of the seat guide rail 100 and a second connecting end 103 at the end of the backrest guide rail 101. A hinge assembly 104 is provided at the connection between the first connecting end 102 and the second connecting end 103, allowing the seat guide rail 100 and the backrest guide rail 101 to connect and form a composite guide rail 105. The hinge assembly 104 enables the seat guide rail 100 and the backrest guide rail 101 to rotate. Compared to the prior art, the guide rail structure provided in this application allows the massage mechanism of the massage chair to move back and forth on the track of the composite guide rail 105, solving the problem that the massage mechanism cannot move back and forth between the backrest guide rail 101 and the seat guide rail 100. Compared to existing technologies, this application, through the setting of the hinge component 104, not only enables the backrest guide rail 101 and the seat guide rail 100 to connect and form a composite guide rail 105 that allows the massage mechanism to move back and forth, but also enables the backrest guide rail 101 and the seat guide rail 100 to rotate, so that the angle changes, allowing the user to achieve continuous massage of the seat and backrest in different states such as lying down or sitting.

[0038] Reference Figure 3 As shown, in one possible implementation, the hinge assembly 104 includes a first connector 106 connected to the seat rail 100 and located at the first connecting end 102, and a second connector 107 connected to the backrest rail 101 and located at the second connecting end 103; the first connector 106 is provided with a first hinge hole 108, and the second connector 107 is provided with a second hinge hole 109; a hinge shaft 110 passes through the first hinge hole 108 and the second hinge hole 109.

[0039] It should be noted that, in this embodiment of the application, by providing a first hinge hole 108 and a second hinge hole 109 on the first connector 106 and the second connector 107 respectively, and by providing the hinge shaft 110, the seat guide rail 100 and the backrest guide rail 101 are rotatably connected. This further ensures that the seat frame 119 and the backrest frame 120 on the massage chair frame can be rotatably connected.

[0040] Reference Figure 3 and Figure 4 As shown, in one possible implementation, a limiting component 111 is provided between the first connecting end 102 and the second connecting end 103; the limiting component 111 includes a fixed blocking member 112 provided at the first connecting end 102 and a rotation limiting member 113 provided at the second connecting end 103; the rotation limiting member 113 can contact the fixed blocking member 112 to block the rotation of the backrest guide rail 101.

[0041] This embodiment of the application limits the rotation angle of the backrest guide rail 101 by providing a fixed blocking member 112 on the first connecting end 102 and a rotation limiting member 113 on the second connecting end 103, through the contact between the rotation limiting member 113 and the fixed blocking member 112. It should be noted that the minimum and maximum included angles between the backrest guide rail 101 and the seat guide rail 100 can be limited. For example, the fixed blocking member 112 blocks the rotation limiting member 113, resulting in a minimum included angle of 96° between the seat guide rail 100 and the backrest guide rail 101. For example, the fixed blocking member 112 blocks the rotation limiting member 113, resulting in a maximum included angle of 160° between the seat guide rail 100 and the backrest guide rail 101. It should be noted that the limiting component 111 can be used to limit and block the minimum angle between the seat guide rail 100 and the backrest guide rail 101, without limiting and blocking the maximum angle between the seat guide rail 100 and the backrest guide rail 101. Alternatively, the limiting component 111 can be used to limit and block both the minimum and maximum angles between the seat guide rail 100 and the backrest guide rail 101.

[0042] Reference Figure 2 As shown, in one feasible embodiment, the backrest guide rail 101 includes a linear guide rail 114 and an arc-shaped guide rail 115 connected at one end, with the other end of the arc-shaped guide rail 115 connected to a second connecting end 103. It should be noted that the arc-shaped guide rail 115 allows the massage mechanism to move smoothly on the composite guide rail 105, making the track direction of the composite guide rail 105 more consistent with the human body curve, which is beneficial for the massage mechanism to effectively massage the seat and back. It should be noted that those skilled in the art can set the central angle of the arc-shaped guide rail 115 as needed; the specific central angle is not specifically limited here. For example, the central angle of the arc-shaped guide rail 115 can be 90°.

[0043] Reference Figure 5 and Figure 7 As shown, in one feasible embodiment, the seat guide rail 100 includes a first slide rail 125 and a first rack 116 disposed within the first slide rail 125; the backrest guide rail 101 includes a second slide rail 126 and a second rack 117 disposed within the second slide rail 126; when the first rack 116 and the second rack 117 are connected to form a composite guide rail 105, their indexing lines align, and the rotation axis of the hinge assembly 104 is located on the indexing line at the alignment point. By setting the rotation axis on the indexing line, it is ensured that the massage mechanism passes smoothly through the hinge assembly 104.

[0044] It should be noted that the composite guide rail 105 includes a slide rail composite guide rail formed by the first slide rail 125 and the second slide rail 126, and a rack composite guide rail formed by the first rack 116 and the second rack 117. Those skilled in the art can make the massage mechanism move simultaneously on both the slide rail composite guide rail and the rack composite guide rail. By setting the slide rail composite guide rail on the basis of the rack composite guide rail, it is beneficial to improve the stability of the massage mechanism at the hinge connection.

[0045] Reference Figure 6 As shown, in one feasible embodiment, the tooth tips of both the first connecting end 102 and the second connecting end 103 are arc surfaces 118, with the center of the arc surface 118 located on the indexing line. Furthermore, in this embodiment, the tooth tips of the connecting ends of the first rack 116 and the second rack 117 are designed as arc surfaces 118, which can further improve the smoothness of the massage mechanism at the connection point of the first rack 116 and the second rack 117, ensuring stable movement of the massage mechanism at the connection point of the seat guide rail 100 and the backrest guide rail 101.

[0046] Reference Figure 6 and Figure 7 As shown, the first rack 116 and the second rack 117 are respectively disposed at the lower part of the first slide rail 125 and the second slide rail 126, that is, the rotation axis of the hinge assembly 104 is located at the lower part of the connection end of the first slide rail 125 and the second slide rail 126. The fixing blocking member 112 and the rotation limiting member 113 are respectively disposed at the upper part of the first slide rail 125 and the second slide rail 126, and are vertically corresponding to the rotation axis. While the fixing blocking member 112 can block the rotation limiting member 113, it connects the upper part of the first slide rail 125 and the second slide rail 126, so that the massage mechanism combined with the rack and pinion guide rail 105 can move continuously back and forth on the first slide rail 125 and the second slide rail 126.

[0047] As one possible implementation, the seat rail 100 and the backrest rail 101 are connected to form at least two composite rails 105. Exemplarily, two composite rails 105 are arranged on the left and right sides of the massage chair. It should be noted that the embodiments of this application are not specifically limited to two composite rails 105 arranged on the left and right sides. In specific applications, those skilled in the art can set the number and position of the composite rails 105 as needed.

[0048] Reference Figure 8 As shown, in a second aspect, this application provides a massage chair frame, including a seat frame 119, a backrest frame 120, and the segmented guide rail structure of the massage chair described above; wherein, the seat guide rail 100 is disposed on the seat frame 119, and the backrest guide rail 101 is disposed on the backrest frame 120.

[0049] The massage chair frame provided in this application embodiment can ensure that the massage mechanism can still move back and forth on the synthetic guide rail 105 when the backrest frame 120 is rotated to different angles, so that the user can perform continuous massage of the seat and back in different postures.

[0050] Reference Figure 8 As shown, in one feasible embodiment, a bottom support structure 121 is provided below the seat frame 119, and a control connecting rod 122 is provided below the backrest frame 120. A telescopic component 123 is provided on the bottom support structure 121. The telescopic end of the telescopic component 123 is connected to the control connecting rod 122 via a connecting lug 124. The telescopic component 123 pushes the backrest frame 120 to rise or fall via the control connecting rod 122. In this embodiment, a bottom support structure 121 is provided below the seat frame 119. The telescopic component 123 and the control connecting rod 122 can drive the backrest frame 120 to rotate and rise or fall, thereby adjusting the angle between the backrest guide rail 101 and the seat guide rail 100, thus enabling the massage chair to achieve massage postures at different angles.

[0051] Thirdly, this application provides a massage chair, including the aforementioned massage chair frame and massage mechanism; the massage mechanism is mounted on a segmented guide rail structure and can reciprocate on the composite guide rail 105. The massage chair provided in this application includes the aforementioned massage chair frame and massage mechanism; wherein the massage mechanism is mounted on the composite guide rail 105 and reciprocates on the composite guide rail 105 by a drive. The massage chair provided by this application ensures that the massage mechanism can still reciprocate on the composite guide rail 105 when the backrest frame 120 is rotated to different angles, facilitating continuous massage of the seat and back for the user in different postures.

[0052] 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.
