Description

Technical Field

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

[0002] Existing massage chairs achieve multi-point massage of areas such as the user's back, waist, and shoulders by driving the massage mechanism to move along a guide rail. In order to expand the massage coverage and improve the massage experience, most products adopt a design that combines rigid guide rails with a walking massage mechanism, allowing the mechanism to move up and down or back and forth along a fixed path.

[0003] However, because rigid guide rails themselves lack the ability to deform, and massage chair backrests are typically ergonomically designed with a curved surface, it's difficult for rigid guide rails to perfectly conform to the curve of the backrest. This structural mismatch prevents the massage mechanism from fully conforming to the user's back contour during operation, especially in areas with significant curvature changes such as the shoulders, neck, and lumbar spine. This can easily lead to massage blind spots or uneven pressure distribution, affecting the accuracy and comfort of the massage.

[0004] While some products attempt to improve the massage effect by increasing the freedom of movement of the mechanism (such as 3D telescopic and 4D kneading), their basic guide rail structure is still limited by a rigid design, failing to fundamentally solve the problem of poor fit. Therefore, how to provide a mechanism that can adapt to the curve of the human back and achieve a highly fitting massage has become a key issue that needs to be addressed in the current field of massage chair technology. Utility Model Content

[0024] Existing massage chairs achieve multi-point massage of areas such as the user's back, waist, and shoulders by driving the massage mechanism to move along a guide rail. In order to expand the massage coverage and improve the massage experience, most products adopt a design that combines rigid guide rails with a walking massage mechanism, allowing the mechanism to move up and down or back and forth along a fixed path.

[0025] However, because rigid guide rails themselves lack the ability to deform, and massage chair backrests are typically ergonomically designed with a curved surface, it's difficult for rigid guide rails to perfectly conform to the curve of the backrest. This structural mismatch prevents the massage mechanism from fully conforming to the user's back contour during operation, especially in areas with significant curvature changes such as the shoulders, neck, and lumbar spine. This can easily lead to massage blind spots or uneven pressure distribution, affecting the accuracy and comfort of the massage.

[0026] Although some products attempt to improve the massage effect by increasing the freedom of movement (such as 3D telescopic and 4D kneading), their basic guide rail structure is still limited by rigid design and cannot fundamentally solve the problem of poor fit.

[0027] To solve the above technical problems, refer to Figure 1 , Figure 2 as well as Figure 4 As shown, this application embodiment provides a massage chair, including a backrest assembly 11, a flexible guide rail 10, and a massage mechanism 12; the backrest assembly 11 includes a support plate 110 and an elastic support structure 111 connected to the support plate 110; the flexible guide rail 10 is connected to the support plate 110 through the elastic support structure 111; the massage mechanism 12 is mounted on the flexible guide rail 10; when the user's back rests against the backrest assembly 11, the massage mechanism 12 is driven to move along the flexible guide rail 10, and the elastic support structure 111 generates an elastic force between the support plate 110 and the massage mechanism 12, so that the massage mechanism 12 abuts against the user's back.

[0028] It should be noted that the massage chair provided in this application embodiment solves the problem that traditional rigid guide rails are difficult to conform to the curve of the human back by introducing a collaborative design of flexible guide rail 10 and elastic support structure 111.

[0029] The backrest assembly 11 of the massage chair in this embodiment consists of a support plate 110 and an elastic support structure 111. A flexible guide rail 10 is connected to the support plate 110 through the elastic support structure 111, and the massage mechanism 12 is mounted on the flexible guide rail 10. When a user leans against the backrest, their back applies pressure to the backrest assembly 11. This pressure is transmitted to the elastic support structure 111 through the flexible guide rail 10, causing it to undergo elastic deformation. This generates an adaptive elastic force between the support plate 110 and the massage mechanism 12. This elastic force pushes the massage mechanism 12 to conform to the user's back, allowing the massage mechanism 12 to adjust its position and angle in real time according to the contour of the human back (especially areas with changing curvature such as the shoulders, neck, and lumbar spine) as it moves along the flexible guide rail 10. This achieves dynamic conformal massage, effectively eliminating massage blind spots and improving the accuracy and comfort of the massage.

[0030] The massage chair provided in this embodiment significantly improves the fit and comfort of the massage. Through the synergistic effect of the flexible guide rail 10 and the elastic support structure 111, the massage mechanism 12 can adaptively adjust its position according to the contour of the user's back during movement, effectively fitting areas with large curvature changes such as the shoulders, neck, and lumbar spine, eliminating the massage blind spots and uneven pressure problems caused by traditional rigid guide rails; at the same time, the cushioning and rebound force provided by the elastic support structure 111 makes the massage intensity gentler and more natural, improving the accuracy and ergonomic fit of the massage, thereby achieving a more comfortable and intelligent full-body fit massage experience.

[0031] Reference Figure 2 , Figure 3 As shown, as an optional implementation, there are multiple elastic support structures 111 arranged sequentially along the extension path of the flexible guide rail 10.

[0032] It should be noted that, in this embodiment of the application, multiple elastic support structures 111 are provided and arranged sequentially along the extension path of the flexible guide rail 10.

[0033] This embodiment of the application forms a continuous and segmented controllable elastic support system by distributing multiple elastic support points below the flexible guide rail 10 at different positions. When a user leans against the massage chair backrest assembly 11, the back pressure is transmitted to the flexible guide rail 10 and is jointly borne by each segment of the elastic support structure 111, resulting in local elastic deformation. Since each elastic support structure 111 can independently respond to pressure changes, the flexible guide rail 10 and the massage mechanism 12 installed on it can achieve differentiated and adaptive fit adjustments in different areas. Especially in areas where the curvature of the human back changes significantly (such as the shoulders and waist), it can accurately match the local contour, improving the dynamic fit and stability of the massage mechanism 12 during operation, thereby achieving a more uniform, comfortable, and blind-spot-free massage experience.

[0034] Reference Figure 3 As shown, as an optional implementation, the elastic support structure 111 includes a plurality of airbags 112; the airbags 112 are provided with air valves, which are used to connect to the inflation / deflation module provided on the massage chair.

[0035] It should be noted that the elastic support structure 111 in this embodiment includes multiple airbags 112, each airbag 112 is equipped with an air valve, and is connected to the inflation / deflation module built into the massage chair through the air valve. Its working principle is as follows: the inflation / deflation module can independently inflate or deflate each airbag 112 according to a preset program or real-time sensing of the user's body shape and pressure distribution, thereby adjusting the expansion degree and support strength of each airbag 112. When the user leans against the backrest, the airbags 112 at different positions provide differentiated elastic support according to the back curve and force requirements, causing the flexible guide rail 10 and the massage mechanism 12 mounted on it to adaptively conform to the user's back contour. This design not only achieves multi-point, adjustable elastic response along the massage path, but also supports dynamic adjustment of the support shape, further improving the fitting accuracy and comfort of the massage mechanism 12 during movement, meeting the personalized massage needs of users with different body types.

[0036] Additionally, it should be noted that when the massage mechanism 12 is not in operation, the airbag 112 is deflated and contracted by controlling the inflation / deflation module, causing the flexible guide rail 10 and the massage mechanism 12 mounted thereon to move away from the user's back, thereby automatically retracting the massage part of the massage mechanism 12 from the back contact surface. The design of this embodiment effectively avoids continuous pressure on the body from hard massage components when not in use, significantly improving the comfort of free leaning in the backrest area; it also achieves intelligent switching between "fitting when working and avoiding when idle," optimizing the daily sitting experience while ensuring the massage effect, and enhancing the product's practicality and human-computer interaction.

[0037] It should be noted that the elastic support structure 111 described above may also include multiple spring elements or other elastic structural components.

[0038] As an optional implementation, the flexible guide rail 10 is divided into multiple adjustment areas along the extension path, and each adjustment area is provided with at least one airbag 112.

[0039] It should be noted that, in this embodiment of the application, the flexible guide rail 10 is divided into multiple adjustment areas along its extension path, and each adjustment area is provided with at least one airbag 112, forming a partitioned and controllable elastic support structure 111.

[0040] It should be noted that by dividing the massage path of the guide rail into independent adjustment zones according to different parts of the human back (such as shoulders, back, waist, and buttocks), each zone is provided with elastic support by a corresponding airbag 112. The inflation and deflation module can independently adjust the air pressure of the airbag 112 in each zone, thereby precisely controlling the support height and firmness of the flexible guide rail 10 in different sections. When the massage mechanism 12 moves on the guide rail, the airbags 112 in each zone can dynamically adjust their deformation according to preset programs or real-time body feedback, so that the massage mechanism 12 always maintains the best contact pressure with the user's back when passing through different body parts, realizing customized and dynamically adaptive precision massage by zone, further improving massage comfort and functionality.

[0041] For example, each adjustment zone can be equipped with 2-3 airbags 112.

[0042] Reference Figure 1 , Figure 2 as well as Figure 4 As shown, in one optional implementation, the backrest assembly 11 includes a back cover 114 and a filling support 115 disposed inside the back cover 114; the back cover 114 is fitted over the flexible guide rail 10, the support plate 110, the elastic support structure 111 and the massage mechanism 12; the filling support 115 is disposed on the side of the support plate 110 away from the elastic support structure 111.

[0043] It should be noted that the backrest assembly 11 includes an outer back cover 114 and an inner filling support 115. The back cover 114 is completely fitted over the flexible guide rail 10, the support plate 110, the elastic support structure 111 and the massage mechanism 12 to form a complete outer covering. The filling support 115 is located on the side of the support plate 110 away from the elastic support structure 111, that is, below the support plate 110.

[0044] It should be noted that the filling support 115 is located on the side of the support plate 110 away from the elastic support structure 111, and below the support plate 110. That is, the support plate 110 serves as the bottom layer structure, with the elastic support structure 111, flexible guide rail 10, and massage mechanism 12 arranged sequentially above it, while the filling support 115 is located on the back of the support plate 110 (the side away from the human body). In this case, the filling support 115 mainly serves as basic support and cushioning, and does not directly participate in the deformation response of the massage area. When the user leans against the backrest, the pressure is transmitted through the back cover 114 to the flexible guide rail 10 and massage mechanism 12, and then acts on the support plate 110 through the elastic support structure 111. The support plate 110 then transmits the force to the filling support 115 to achieve overall support. In this structure, the elastic support structure 111 independently responds to massage needs, allowing the flexible guide rail 10 and massage mechanism 12 to achieve precise contact movement without interference from the filling, ensuring the sensitivity and stability of the massage function.

[0045] It should be noted that the filling support 115 primarily serves as the basic support and force transfer element, therefore it needs to possess a certain degree of structural rigidity and compressive strength to ensure the overall stability and durability of the backrest. To meet this requirement, the filling support 115 can be made of materials such as high-density sponge, rigid polyurethane foam, EVA foam, or fiberglass reinforced plastic sheets. Among these, high-density sponge or rigid PU foam can provide moderate cushioning while maintaining shape stability; EVA foam has good resilience and resistance to permanent compression deformation, making it suitable for long-term load-bearing use; for higher strength support, thin-layer fiberglass reinforced plastic or engineering plastic sheets can also be selected as the support structure.

[0046] In another alternative implementation, refer to Figure 4As shown, the filling support 115 is positioned above the support plate 110, specifically between the support plate 110 and the user's back. Its layout provides space for the flexible guide rail 10 and the massage mechanism 12. Specifically, the filling support 115 has grooves or clearance channels corresponding to key massage pathways such as the shoulders, back, and waist. The flexible guide rail 10 and the elastic support structure 111 are embedded within these channels, allowing the massage mechanism 12 to move freely within them. When the user leans against it, the area of ​​the filling support 115 not occupied by the guide rail provides a uniform and soft support. During massage, the elastic support structure 111 deforms in a controlled manner, causing the flexible guide rail 10 and the massage mechanism 12 to push upwards through the reserved space, conforming to the curve of the user's back for massage. This design achieves structural integration, preserving the overall comfortable sitting experience provided by the filling while ensuring the dynamic operation and precise fit of the massage components, thus balancing daily comfort and functional needs.

[0047] Reference Figure 4 As shown, as an optional implementation, the massage mechanism 12 is covered with a wear-resistant cloth cover 120 to isolate the massage head from the back cover 114.

[0048] It should be noted that the massage mechanism 12 is covered with a wear-resistant cloth cover 120, which is located between the massage head of the massage mechanism 12 and the backrest cover, and serves as a physical barrier.

[0049] When the massage mechanism 12 moves along the flexible guide rail 10 and massages the user's back, the wear-resistant cloth cover 120 can effectively prevent the hard massage head from directly rubbing or piercing the backrest cover, avoiding wear, pilling, or even cracking of the cover material due to long-term reciprocating motion, thereby extending the service life of the backrest outer layer; at the same time, the wear-resistant cloth cover 120 has a certain degree of flexibility and sliding, which does not hinder the normal extension and kneading action of the massage head, and allows the force to be smoothly transmitted to the human body through the cloth cover, improving the softness and skin-friendly feel of the contact surface, and further optimizing the comfort and safety during the massage process.

[0050] As an optional implementation, the back cover 114 includes a mesh nylon layer and a wear-resistant fabric layer stacked sequentially from the inside out.

[0051] It should be noted that the back cover 114 adopts a multi-layer composite structure, with a mesh nylon layer and a wear-resistant fabric layer arranged sequentially from the inside out. The mesh nylon layer has excellent breathability and elasticity; when fitted inside, it improves the heat dissipation of the backrest, reducing stuffiness during use. Its elastic structure also adapts to the dynamic movements of the flexible guide rail 10 and the massage mechanism 12, ensuring effective transmission of massage force. The outer wear-resistant fabric layer provides high-strength surface protection, resisting daily leaning, friction, and external scratches, extending the cover's lifespan. This two-layer structure balances comfort and breathability while enhancing the overall durability and structural stability of the cover, ensuring it maintains its good appearance and functional integrity even under repeated movement of the massage mechanism 12 and long-term use.

[0052] Reference Figure 5 , Figure 6 As shown, the flexible guide rail 10 provided in this application includes a strip-shaped conductive component 100, a sliding conductive component 101, and at least one flexible rack 102; the flexible rack 102 is used for meshing and transmission with gears on the massage mechanism 12, the strip-shaped conductive component 100 is used for electrical connection with an external power source, and is installed along the extension path of the flexible rack 102; the sliding conductive component 101 includes a mounting base 103 and a conductive structural member 104; the mounting base 103 is fixedly installed on the massage mechanism 12, and when the massage mechanism 12 moves along the flexible rack 102, the conductive structural member 104 is fixed on the mounting base 103 and slides in contact with the surface of the strip-shaped conductive component 100 to supply power to the massage mechanism 12.

[0053] It should be noted that the sliding conductive device provided in this application embodiment is based on the technical principle of integrating the transmission function and the power supply function in a coordinated design: the flexible rack 102 is used as the transmission track of the massage mechanism 12, and a strip conductive component 100 is set on the extension path of the flexible rack 102 as a fixed conductive busbar; the sliding conductive component 101 is installed on the moving massage mechanism 12, and its conductive structure 104 maintains sliding contact with the surface of the strip conductive component 100.

[0054] During operation, as the massage mechanism 12 reciprocates through the engagement of gears and the flexible rack 102, the conductive structural component 104 fixed on the mechanism slides along the surface of the strip-shaped conductive assembly 100, continuously acquiring electrical energy and supplying it to the electrical components within the massage mechanism 12. These electrical components include the motors of the massage elements within the massage mechanism 12, the drive motor of the massage mechanism 12, and other electrical modules. Overall, this embodiment of the application enables simultaneous power supply and movement.

[0055] Reference Figure 7As shown, in one optional embodiment, the strip conductive assembly 100 includes an insulating protective strip 105 and a conductive strip 106. The insulating protective strip 105 is provided with at least one first receiving groove 107. The conductive strip 106 is embedded in the first receiving groove 107. The surface of the conductive strip 106 facing away from the bottom of the first receiving groove 107 contacts the conductive structural member 104. The groove walls on both sides of the first receiving groove 107 are provided with inwardly extending first hook portions 108, which are engaged with both sides of the conductive strip 106.

[0056] It should be noted that, in this embodiment of the application, a first receiving groove 107 with a first hook part 108 is provided on the insulating protective strip 105, and the conductive strip 106 is embedded therein, thereby achieving reliable positioning and insulation protection of the conductive strip 106.

[0057] Among them, reference Figure 5 As shown, there are two parallel flexible guide rails 10 located on both sides of the massage mechanism 12; it also includes two crossbeams 113, with the ends of the crossbeams 113 connected to the ends of the two flexible guide rails 10 respectively.

[0058] As an optional implementation, at least one end of the two crossbeams 113 is provided with a limit switch, and the massage mechanism 12 is provided with a corresponding limit part that can abut against the limit switch.

[0059] It should be noted that at least one end of each of the two crossbeams 113 is equipped with a limit switch, and the massage mechanism 12 is correspondingly equipped with a limiting part that can abut against the limit switch. When the massage mechanism 12 moves along the flexible guide rail 10 to the end position of the preset stroke, the limiting part on it touches the limit switch at the end of the crossbeam 113, triggering a signal feedback to the control system, thereby immediately stopping the drive motor or reversing the operation, achieving precise control of the movement stroke of the massage mechanism 12. This structure effectively prevents the mechanism from detaching from the guide rail or impacting the backrest structure due to excessive movement, thus ensuring not only the safety and stability of the equipment operation, but also ensuring that the massage path is always within the effective area of ​​the human back, improving the accuracy and reliability of the massage process.

[0060] 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.
