Description

Technical Field

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

[0002] Existing massage chair frames typically feature a rigid transition rail between the backrest and seat rails. This creates a significant gap during adjustment, necessitating segmented rack and pinion mechanisms to ensure the massage mechanism can pass smoothly through the transition rail at a specific angle. Due to limitations in the rail technology, when the backrest and seat rails open too wide, the massage mechanism exhibits noticeable vibration at the junctions of the transition rail and the backrest / seat rails, and further, excessive movement can produce structural impact noises. Furthermore, current massage chair frames cannot achieve a perfectly horizontal seat and backrest, meaning the angle between the backrest and seat is not 180°, thus negatively impacting the chair's functionality and usability. Summary of the Invention

[0003] The purpose of this application is to provide a guide rail and a massage chair frame, which, through improvements to the guide rail structure, enables the backrest and seat of the massage chair frame to form an angle of 180°, and allows the massage mechanism to move smoothly.

Detailed Implementation

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Reference Figure 1 , Figure 2 as well as Figure 3As shown, this application embodiment provides a guide rail installed on the frame of a massage chair, including a backrest guide rail 100, a seat guide rail 101, and a flexible guide rail assembly 102 arranged along the guide rail extension path; one end of the flexible guide rail assembly 102 is connected to the backrest guide rail 100, and the other end is connected to the seat guide rail 101; the flexible guide rail assembly 102 includes a plurality of flexible rail modules 103 arranged along the guide rail extension path; see reference Figure 4 , Figure 5 as well as Figure 6 As shown, there is a gap 104 between adjacent flexible rail modules 103, and adjacent flexible rail modules 103 are connected by a hinge 105; the rotation axis of the hinge 105 is perpendicular to the extension path of the guide rail, and the flexible rail module 103 adjusts the size of the gap 104 by rotating to make the flexible guide rail assembly 102 bend, thereby changing the angle between the backrest guide rail 100 and the seat guide rail 101.

[0042] It should be noted that by providing a gap 104 between adjacent flexible rail modules 103, the adjacent flexible rail modules 103 can rotate by an angle A via the hinge 105; wherein, the bending angle of the flexible guide rail assembly 102 is the sum of multiple angles A. Those skilled in the art can set the size of the gap 104 as needed, that is, set the size of the rotation angle A of the adjacent flexible rail modules 103 through the limiting structure. For example, when the angle between the seat guide rail 101 and the backrest guide rail 100 is 180°, the flexible guide rail assembly 102 is horizontally positioned, the gap 104 is located on the upper side of the adjacent flexible rail modules 103, and the lower sides of the adjacent flexible rail modules 103 are in contact. After the flexible guide rail assembly 102 bends upward to its maximum angle, the gap 104 is located on the lower side of the adjacent flexible rail modules 103, and the upper sides of the adjacent flexible rail modules 103 are in contact. Furthermore, those skilled in the art can set the number of flexible rail modules 103 and the maximum rotation angle between adjacent flexible rail modules 103 as needed.

[0043] This application provides a guide rail for installation on a massage chair frame, including a backrest guide rail 100, a seat guide rail 101, and a flexible guide rail assembly 102 arranged along the guide rail extension path. In this application embodiment, the flexible guide rail assembly 102 connects the backrest guide rail 100 and the seat guide rail 101, enabling a flexible connection between them. The flexible guide rail assembly 102 includes multiple flexible rail modules 103 arranged along the guide rail extension path. By providing a gap 104 between adjacent flexible rail modules 103 and allowing adjacent flexible rail modules 103 to rotate within the provided gap 104, the flexible guide rail assembly 102 can bend, thereby changing the included angle between the backrest guide rail 100 and the seat guide rail 101. In this embodiment, the connection of the flexible guide rail assembly 102 enables the massage mechanism 119 to move smoothly without noticeable jumping or abnormal noise when passing the connection point with the backrest guide rail 100 or the seat guide rail 101.

[0044] Reference Figure 7 As shown, in one optional implementation, the flexible guide rail assembly 102 is provided with a connecting rod hinge 106. The connecting rod hinge 106 includes a plurality of connecting rods 107 arranged along the extension path of the guide rail and a connecting rod rotation assembly 108 connecting the ends of adjacent connecting rods 107. The rotation axis of the connecting rod rotation assembly 108 is parallel to the rotation axis of the hinge member 105. The connecting rod rotation assembly 108 is provided in a one-to-one correspondence with the flexible rail module 103. The connecting rod rotation assembly 108 includes a first rotating member 109 and a second rotating member 110 arranged alternately along the extension path. The first rotating member 109 is slidably disposed on the corresponding flexible rail module 103, and the sliding direction is perpendicular to the extension path of the guide rail.

[0045] Figure 13 and Figure 14 This is a schematic diagram of the structure of the flexible rail module 103 provided in an embodiment of this application.

[0046] Figure 15 This is a schematic diagram of the inner surface structure of the flexible guide rail assembly 102 provided in an embodiment of this application.

[0047] Figure 16 This is a schematic diagram of the horizontally placed flexible guide rail assembly 102 provided in an embodiment of this application. Figure 17 This is a schematic diagram of the bending structure of the flexible guide rail assembly 102 provided in the embodiment of this application.

[0048] Reference Figure 7As shown, further, the linkage hinge 106 in this embodiment enhances the strength of the flexible guide rail assembly 102 along the guide rail extension path. The first rotating member 109 in this embodiment allows one end of the linkage 107 to slide in a direction perpendicular to the guide rail extension path. When the flexible guide rail assembly 102 bends, the linkage 107 ensures that the rotation angle A between adjacent flexible rail modules 103 is the same, facilitating uniform rotation of the flexible rail modules 103.

[0049] Reference Figure 8 As shown, in one optional implementation, the flexible rail module 103 includes a first flexible rail module 111 and a second flexible rail module 112 arranged alternately along the extension path; there are two sets of connecting rod hinges 106 extending on both sides of the guide rail extension path, the first rotating member 109 of one set of connecting rod hinges 106 is slidably disposed in the first flexible rail module 111, and the first rotating member 109 of the other set of connecting rod hinges 106 is slidably disposed in the second flexible rail module 112.

[0050] This application embodiment provides a specific arrangement of the flexible guide rail assembly 102 and the connecting rod hinge 106. The arrangement of two connecting rod hinges 106 enables the flexible rail assembly to reliably connect the backrest guide rail 100 and the seat guide rail 101. Specifically, the first rotating member 109 of one set of connecting rod hinges 106 is slidably disposed on the first flexible rail module 111, and the first rotating member 109 of the other set of connecting rod hinges 106 is slidably disposed on the second flexible rail module 112. The alternating arrangement of the first flexible rail module 111 and the second flexible rail module 112 allows the two sets of connecting rod hinges 106 to slide in a staggered manner, which facilitates uniform bending of the flexible guide rail assembly 102.

[0051] Reference Figure 9 As shown, as an optional implementation, the linkage hinge 106 has two sets and is symmetrically arranged about the guide rail extension path. For example, the flexible rail module 103 corresponding to the first rotating member 109 has a groove 113 that intersects the guide rail extension path perpendicularly. Two sliders located on both sides of the guide rail extension path are provided in the groove 113, and the two sliders are respectively connected to the two first rotating members.

[0052] Reference Figure 9 and Figure 10 As shown, a groove 113 can be provided that intersects the guide rail extension path, or two grooves 113 can be provided on both sides of the guide rail extension path. The purpose of providing the grooves 113 is to enable the connecting rods 107, which are symmetrical about the guide rail extension path, to slide in alignment.

[0053] For example, the linkage hinge 106 has two sets and is symmetrically arranged about the extension path of the guide rail. The flexible rail module 103 corresponding to the first rotating member 109 is provided with a first slide groove 120 and a second slide groove 121 that are perpendicular to the extension path of the guide rail, respectively. The first slide groove 120 and the second slide groove 121 are spaced apart along the extension path. One set of first rotating members is connected to the first slide groove 120 through a first slider, and the other set of first rotating members is connected to the second slide groove 121 through a second slider. Unlike the above embodiment, the embodiment of this application provides two slide grooves 113 that are staggered along the extension path of the guide rail on a flexible rail module 103, thereby realizing the staggered sliding of the two sets of linkage hinges 106.

[0054] Reference Figure 3 As shown, as an optional implementation, it also includes a rack 114 passing through the backrest guide rail 100, the flexible guide rail assembly 102, and the seat guide rail 101. The tooth surface of the rack 114 is parallel to the axis of the hinge member 105; each flexible rail module 103 is provided with multiple teeth. Further, this application embodiment specifically discloses a rack 114 disposed on the guide rail, and the rack 114 in this application embodiment is arranged along the extension path of the guide rail. It should be noted that each flexible rail module 103 in this application embodiment corresponds to multiple teeth on the rack 114. While ensuring that the flexible guide rail assembly 102 can bend, the above arrangement can reduce the number of flexible rail modules 103, which is beneficial for reducing costs and simplifying the structure.

[0055] Reference Figure 11 As shown, for example, the flexible rail module 103 is a U-shaped groove 115, the hinge 105 is disposed in the middle of the U-shaped groove 115, and the rack 114 is disposed on one side wall of the U-shaped groove 115; the other side wall of the U-shaped groove 115 is provided with a transition connector 116, which is used to connect adjacent U-shaped grooves 115.

[0056] As an optional implementation, a backrest adapter 117 and a seat adapter 118 are respectively hinged to the flexible rail modules 103 at both ends of the flexible rail assembly 102. The backrest adapter 117 is connected to the backrest guide rail 100, and the seat adapter 118 is connected to the seat guide rail 101. One end of the connecting rod hinge 106 is hinged to the backrest adapter 117 through the connecting rod 107, and the other end is hinged to the seat adapter 118 through the connecting rod 107.

[0057] Reference Figure 1 As shown, this application embodiment provides a massage chair frame, including at least one of the aforementioned guide rails, on which a massage mechanism 119 that moves along an extension path is disposed. For example, there are two of the aforementioned guide rails, located on both sides of the massage chair frame, and the massage mechanism 119 is mounted on the guide rails and can move back and forth via the guide rails.

[0058] The massage chair frame provided in this application includes the aforementioned guide rails, and a massage mechanism 119 is mounted on the guide rails. By improving the guide rail structure, this application enables the angle between the backrest guide rail 100 and the seat guide rail 101 of the massage chair frame to be 180°, allowing the massage chair frame to lie flat and enhancing its applicability. Furthermore, the flexible guide rail assembly 102 in this application allows the massage mechanism 119 to move smoothly without noticeable jumping or abnormal noise when passing through the connection points with the backrest guide rail 100 or the seat guide rail 101. Therefore, this application effectively improves the usability of the massage chair frame.

[0059] 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.
