Description

Technical Field

[0001] The present application relates to the field of massage technology, and in particular to a movable sealing structure and a massage chair. Background Art

[0002] With the improvement of living standards, massage chairs have gained widespread use and rapid development in daily life. Massage chairs typically utilize multiple components, including massage elements, a support frame, a cape, and guide rails. The cape plays a particularly important role, primarily protecting internal components and preventing dust and other foreign matter from entering the device, thereby ensuring proper operation and longevity. To ensure effective movement of the massage elements, the cape is typically designed with openings, allowing them to move smoothly through them. However, these openings also pose a potential risk of foreign matter entering the cape.

[0003] To address this problem, two main solutions are currently available. The first employs a zipper structure at the opening, which opens and closes with the movement of a slider, effectively blocking the entry of foreign matter. The second approach involves covering the cloak's opening with two elastic strips. The ends of these strips are connected to a support frame, allowing them to expand and contract with the movement of the massage element. The elasticity of the strips allows the opening to be automatically shielded as the massage element moves, preventing the entry of foreign matter.

[0004] However, while these technical solutions have addressed the issue to a certain extent, some shortcomings remain. First, in solutions employing a zipper structure, the zipper is prone to jamming, which not only affects the smooth movement of the massage element and, in turn, the massage effect, but can also shorten the lifespan of the device. Second, in solutions employing elastic strips, when one end of the elastic strip is stretched, the other end contracts and may wrinkle. Such wrinkles not only affect the shielding effect but can also make the cloak look unsightly, further impacting the user experience. Utility Model Content

[0005] The purpose of this application is to provide a movable sealing structure and a massage chair to address the deficiencies in the above-mentioned prior art.

[0006] To achieve the above objectives, the technical solutions adopted in the embodiments of the present application are as follows:

[0007] One aspect of an embodiment of the present application provides a movable sealing structure, including a cloak, a support assembly, and a massage piece. The cloak is installed on a chair frame, and the support assembly is slidably connected to the chair frame. A through hole is opened in the cloak, and the length of the through hole is adapted to the sliding range of the support assembly. The support assembly passes through the through hole and is driven and connected to the massage piece. The support assembly is driven to slide to drive the massage piece to slide along the through hole. A rotating belt is installed at a position of the cloak corresponding to the through hole to cover the through hole. The support assembly is driven and connected to the rotating belt, and the support assembly is driven to slide to drive the rotating belt to rotate on a fixed axis.

[0008] Optionally, the support assembly includes a support frame slidably connected to the chair frame and a support rod connected to the support frame, one end of the support rod passing through the through hole is drive-connected to the massage piece, and the other end of the support rod is drive-connected to the rotating belt.

[0009] Optionally, the support rod is rotatably connected to the support frame.

[0010] Optionally, the movable sealing structure further includes a reset member, and two ends of the reset member are respectively in contact with the support frame and the support rod.

[0011] Optionally, the movable sealing structure also includes a baffle, which is installed on the cloak to cover the through hole, and the rotating belt is installed on the side of the baffle away from the massage part. A sliding groove is opened at the position of the baffle corresponding to the support rod, and the length of the sliding groove is adapted to the sliding range of the support rod.

[0012] Optionally, mounting shafts are respectively provided at both ends of the baffle on a side away from the massage element, and the rotating belt is sequentially wound around the two mounting shafts.

[0013] Optionally, the movable sealing structure further includes a clamping member, and the support assembly is slidably clamped on the chair frame via the clamping member.

[0014] Optionally, the movable sealing structure further includes a driving member, which is mounted on the chair frame and is drivingly connected to the support assembly.

[0015] Another aspect of an embodiment of the present application provides a massage chair, comprising a chair frame and any one of the above-mentioned movable sealing structures, wherein a cloak of the movable sealing structure is mounted on the chair frame, and a support assembly of the movable sealing structure is slidably connected to the chair frame.

[0016] Optionally, the massage chair further comprises a backrest, and the cloak with a movable sealing structure is mounted on the chair frame via the backrest.

[0017] The beneficial effects of this application include:

[0018] The present application provides a movable sealing structure comprising a cape, a support assembly, and a massage member. The cape is mounted on a chair frame, and the support assembly is slidably connected to the chair frame, ensuring the stability of the movable sealing structure and the flexibility of the massage member. A through hole is provided in the cape, the length of which is adapted to the sliding range of the support assembly. This ensures that when the support assembly is externally driven, it can always maintain a driving connection with the massage member through the through hole during the sliding process. This allows the massage member to slide smoothly along the through hole under the drive of the support assembly, thereby improving the massage effect and extending the service life. Furthermore, a rotating belt is installed at the position of the cape corresponding to the through hole to block the through hole and prevent the entry of foreign matter. The belt also drives the support assembly to the rotating belt. As a result, the sliding of the support assembly not only drives the massage member to slide, but also drives the rotating belt to rotate about its fixed axis. The rotating belt automatically adjusts its position during the rotation of the fixed axis, ensuring that the rotating belt continuously covers the through hole throughout the entire sliding process of the support assembly. This avoids the wrinkling and overlapping problems common in traditional elastic strip designs, greatly improving the shielding effect and the overall aesthetics of the device.

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0026] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application as claimed, but merely represents selected embodiments of the present application. It should be noted that, unless there is a conflict, the various features of the embodiments of the present application may be combined with each other, and the combined embodiments are still within the scope of protection of the present application.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0028] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use.

[0029] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0030] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0031] In one aspect of the embodiment of the present application, a movable sealing structure 10 is provided, such as Figures 1 to 3As shown, it includes a cloak 11, a support component 12, and a massage part 13. The cloak 11 is installed on the chair frame 20, and the support component 12 is slidably connected to the chair frame 20. A through hole 11a is opened in the cloak 11, and the length of the through hole 11a is adapted to the sliding range of the support component 12. The support component 12 passes through the through hole 11a and is driven and connected to the massage part 13. The support component 12 is driven to slide to drive the massage part 13 to slide along the through hole 11a. A rotating belt 14 is installed at a position of the cloak 11 corresponding to the through hole 11a to cover the through hole 11a. The support component 12 is driven and connected to the rotating belt 14. The support component 12 is driven to slide to drive the rotating belt 14 to rotate on a fixed axis.

[0032] Specifically, the cape 11 is mounted on the chair frame 20, and the support assembly 12 is slidably connected to the chair frame 20, ensuring the stability of the movable sealing structure 10 and the flexibility of the massage elements 13. A through hole 11a is defined in the cape 11, the length of which is adapted to the sliding range of the support assembly 12. This ensures that when the support assembly 12 is externally driven, it can always maintain a driving connection with the massage elements 13 through the through hole 11a during the sliding process. Driven by the support assembly 12, the massage elements 13 can also slide smoothly along the through hole 11a, thereby improving the massage effect and extending the service life. In addition, a rotating belt 14 is installed at the position of the cloak 11 corresponding to the through hole 11a to cover the through hole 11a and prevent external foreign matter from entering, and the support assembly 12 is driven and connected to the rotating belt 14. Therefore, the sliding of the support assembly 12 not only drives the massage part 13 to slide, but also drives the rotating belt 14 to rotate around its fixed axis. The rotating belt 14 will automatically adjust its position during the fixed axis rotation, thereby ensuring that the rotating belt 14 can continue to cover the through hole 11a during the entire sliding process of the support assembly 12, and avoids the wrinkle and overlap problems common in traditional elastic strip designs, greatly improving the shielding effect and the overall aesthetics of the equipment.

[0033] It should be noted that the rotating belt 14 can be in the form of a movable track. This design enables the rotating belt 14 to move flexibly when the support assembly 12 slides. The movable track is usually made of fabric strips, belts, elastic synthetic materials or other soft materials. The selection of soft materials not only ensures the flexibility and stability of the track during movement, but also ensures that it can maintain a good shielding effect and is not easily damaged after long-term use. In addition to the improvement of the shielding effect, the design of the movable track also brings convenience to maintenance and replacement. Tracks made of soft materials are usually lighter, easier to install and replace, and improve convenience.

[0034] Optionally, the support assembly 12 includes a support frame 121 slidably connected to the chair frame 20 and a support rod 122 connected to the support frame 121, one end of the support rod 122 passing through the through hole 11a is drive-connected to the massage part 13, and the other end of the support rod 122 is drive-connected to the rotating belt 14.

[0035] Specifically, if Figure 1 As shown, the support frame 121 is slidably connected to the chair frame 20, allowing the support frame 121 to move freely on the chair frame 20. The support frame 121 is connected to the massage element 13 via a support rod 122. One end of the support rod 122 passes through the through hole 11a in the cloak 11 and is driven by the massage element 13. This means that when the support frame 121 slides, the support rod 122 will also move, thereby driving the massage element 13 located on the side of the cloak 11 closer to the human back to slide along the through hole 11a, completing the massage of different areas of the human back. At the other end of the support rod 122, it is driven by the rotating belt 14. This connection design allows the support rod 122 to simultaneously drive the rotating belt 14 to rotate around its fixed axis while driving the massage element 13 to move.

[0036] In this way, the support frame 121 and massage elements 13 are located on either side of the through-hole 11a of the cloak 11. The support frame 121 can be cleverly concealed behind the rotating belt 14, preventing the exposed support assembly 12 from affecting the aesthetics of the device. This concealed design not only enhances the overall appearance of the device but also reduces the risk of damage to the support assembly 12 due to external factors. Secondly, the massage elements 13 are positioned on the side of the cloak 11 closest to the back, enabling them to precisely massage multiple areas of the back, driven by the support assembly 12. This design not only improves the massage effect but also enhances the user's comfort. Furthermore, the double-ended connection of the support rod 122 further enhances the stability and coordination of the system. Through the bidirectional connection of the support rod 122, the support frame 121, massage elements 13, and rotating belt 14 form a tight mechanical system. This allows the rotating belt 14 to rotate synchronously with the movement of the massage elements 13, effectively shielding the through-hole 11a of the cloak 11 and preventing the intrusion of foreign matter.

[0037] In general, this design achieves flexible movement and effective shielding of the massage element 13, greatly improves the aesthetics and service life of the device, and cleverly solves the problem of device performance degradation caused by loose shielding in traditional designs.

[0038] Optionally, the support rod 122 is rotatably connected to the support frame 121 .

[0039] Specifically, if Figure 3As shown, a rotational connection design is adopted between the support rod 122 and the support frame 121, which provides structural stability and flexibility. This connection method can be achieved through a pin 123 or other hinged methods. The rotational connection design enables the support rod 122 to rotate around the support frame 121, which means that the massage element 13 connected to the support rod 122 can also adjust its angle accordingly, allowing the massage element 13 to be adjusted in multiple dimensions, significantly improving the adaptability of the massage chair. Whether it is for users of different body shapes or for the needs of specific massage areas, the massage element 13 can be finely adjusted through the rotation of the support rod 122 to adapt to the body curves of different users, providing a more fitting and effective massage, and achieving the best massage effect.

[0040] The hinged connection design allows the massage element 13 to adapt to the individual needs of different users, allowing the device to flexibly adjust both the massage intensity and the massage angle. Furthermore, the pivoting connection between the support rod 122 and the support frame 121 improves the durability and stability of the device. Because the pin 123 or hinged structure has high mechanical strength and reliability, the support rod 122 will not easily loosen or detach during use, ensuring the stability and safety of the device during long-term, high-frequency use. This structural design not only ensures efficient operation of the device, but also reduces the frequency and cost of maintenance, thereby extending the device's service life.

[0041] Optionally, the movable sealing structure 10 further includes a reset member 124 , and two ends of the reset member 124 are respectively in contact with the support frame 121 and the support rod 122 .

[0042] Specifically, if Figure 3 As shown, the reset member 124 can be a torsion spring, a compression spring, an elastic band or other structural forms with elastic recovery function. The reset member 124 is usually installed between the support frame 121 and the support rod 122, and its two ends are respectively abutted against the support frame 121 and the support rod 122. When the support rod 122 rotates relative to the support frame 121 during use, the reset member 124 will deform with the rotation of the support rod 122, thereby storing elastic energy. This energy storage mechanism enables the reset member 124 to release the stored energy when the support rod 122 is no longer subjected to external force, pushing the support rod 122 to automatically rotate, so that the massage member 13 returns to the preset initial position.

[0043] The introduction of the reset element 124 ensures that the massage element 13 automatically returns to its initial position after each use, preventing device malfunction or inconvenience caused by the massage element 13 not returning to its original position. This not only improves device reliability but also reduces the number of user steps, making the device more convenient to use. Furthermore, by storing and releasing energy, the reset element 124 provides moderate damping while ensuring flexible rotation of the support rod 122, preventing damage to the support rod 122 and massage element 13 due to excessive swinging or otherwise affecting the device's effectiveness.

[0044] Furthermore, the design of the reset element 124 effectively extends the lifespan of the device. Because the reset element 124 automatically resets the massage element 13, manual adjustments are less frequent and wear and tear on the device's components is reduced. Furthermore, the elastic recovery function of the reset element 124 maintains the stability of the device even when it is not in use for extended periods, preventing components from loosening or becoming misaligned. This is crucial for maintaining the long-term stable operation of the device.

[0045] Optionally, the movable sealing structure 10 further includes a baffle 15, which is mounted on the cloak 11 to block the through hole 11a, and the rotating belt 14 is mounted on the side of the baffle 15 facing away from the massage part 13. A slide groove 15a is provided at a position of the baffle 15 corresponding to the support rod 122, and the length of the slide groove 15a is adapted to the sliding range of the support rod 122.

[0046] Specifically, if Figure 1 As shown, baffle 15 is sewn onto cloak 11 and fixed at the location of through-hole 11a. Its primary function is to block through-hole 11a and prevent foreign matter from entering the internal mechanism. Baffle 15 is typically made of a hard material such as plastic. These materials offer excellent rigidity and durability, maintaining their shape and resisting deformation or damage over extended use. The use of hard materials also provides baffle 15 with excellent protection, resisting external impacts and providing additional protection for the internal mechanical structure.

[0047] The baffle 15 is provided with a chute 15a, the length of which matches the sliding range of the support rod 122, ensuring that the support rod 122 follows a predetermined trajectory during sliding. The width of the chute 15a matches the outer diameter of the support rod 122. This design securely confines the support rod 122 within the chute 15a, preventing lateral displacement or wobbling, thereby ensuring stable sliding of the support rod 122. Guided by the chute 15a, the support rod 122, driven by the support frame 121, slides smoothly along the surface of the cloak 11, maintaining a stable connection with the massage element 13 during the sliding process.

[0048] The rotating belt 14 is mounted on the side of the baffle 15 facing away from the massage element 13. Its primary function is to further shield the chute 15a. This design not only provides an additional barrier but also conceals the sliding path of the support rod 122, enhancing the overall aesthetics of the device. The flexibility and shielding effect of the rotating belt 14 ensure that the chute 15a remains sealed during use, preventing dust and other impurities from entering the chute 15a and ensuring the long-term smooth operation of the sliding system.

[0049] Overall, the combined design of the baffle 15 and the chute 15a ensures smoother and more stable sliding of the support rod 122, effectively preventing any jamming or wear caused by the support rod 122 deviating from the chute 15a. This design enhances the reliability and durability of the system, ensuring the massage device maintains efficient operation even during extended use. Furthermore, the shielding effect of the rotating belt 14 further enhances the device's protective capabilities, preventing external contaminants from entering the chute 15a, thereby extending the life of the sliding mechanism.

[0050] Optionally, mounting shafts 151 are respectively provided at both ends of the baffle 15 on a side away from the massage element 13 , and the rotating belt 14 is sequentially wound around the two mounting shafts 151 .

[0051] Specifically, if Figure 3 As shown, the introduction of the mounting shaft 151 provides a fixed support point for the operation of the rotating belt 14, allowing the rotating belt 14 to rotate synchronously and smoothly when the support rod 122 slides, avoiding the problem of incomplete shielding caused by loosening or offsetting of the rotating belt 14. The mounting shaft 151 serves as the core support structure of the rotating belt 14, ensuring that the rotating belt 14 maintains appropriate tension and stability when moving along the surface of the baffle 15. By arranging the mounting shafts 151 at both ends of the baffle 15, the rotating belt 14 is sequentially wound around the two mounting shafts 151. Through these two support points, the rotating belt 14 can rotate with the support rod 122 when it slides, effectively shielding the slide groove 15a and preventing external dust or impurities from entering the internal mechanism.

[0052] The precise positioning of the mounting shaft 151 and the winding arrangement of the rotating belt 14 ensure that the belt 14 maintains a tight fit within the chute 15a throughout the entire sliding process. This tight fit ensures that the chute 15a remains effectively shielded during the sliding of the support rod 122, further enhancing the protective effectiveness and overall performance of the sealing structure. Furthermore, the smooth rotation of the rotating belt 14 reduces friction and wear between moving parts, significantly extending the equipment's service life and reducing maintenance costs.

[0053] Optionally, the movable sealing structure 10 further includes a clamping member 16 , and the support assembly 12 is slidably clamped on the chair frame 20 via the clamping member 16 .

[0054] Specifically, if Figures 1 to 3 As shown, the primary function of clamping member 16 is to connect support frame 121 of support assembly 12 to chair frame 20 via a sliding clamping mechanism, while allowing it to slide along the rods of chair frame 20. The design of clamping member 16 typically takes into account precise dimensions and shape to ensure that support frame 121 is securely clamped to the rods of chair frame 20 while providing sufficient flexibility to allow sliding. This design ensures that support frame 121 always moves along a predetermined track during sliding, avoiding any lateral or vertical deviation, thereby maintaining smooth and precise sliding.

[0055] Clamps 16 are provided at each end of the support frame 121. These clamps secure the support frame 121 to the rods of the chair frame 20 through a tight clamping force, allowing it to slide linearly along the rods. The rods of the chair frame 20 effectively function as slide rails, providing a path and direction for the support frame 121 to slide. This design ensures that the support frame 121 not only has a high degree of guidance but also provides stable support, ensuring smooth movement of the massage element 13 during operation.

[0056] Overall, the combination of the clamping member 16 and the chair frame 20 provides excellent sliding guidance for the support frame 121, which is crucial for ensuring the accurate positioning of the massage element 13. Because the clamping force of the clamping member 16 is evenly distributed across both ends of the support frame 121, the support frame 121 experiences a more even force during sliding, reducing tilting or shaking caused by uneven force on one side. This uniform force not only improves the sliding efficiency of the support frame 121 but also reduces friction and wear, thereby extending the service life of the device.

[0057] Optionally, the movable sealing structure 10 further includes a driving member 17 , which is mounted on the chair frame 20 and is drivingly connected to the supporting assembly 12 .

[0058] Specifically, if Figures 1 to 3 As shown, the function of the driving member 17 is to provide the necessary driving force for the support assembly 12 to slide along the predetermined path of the chair frame 20. The driving member 17 is fixedly mounted on the bottom or side of the chair frame 20 and is drivingly connected to the support frame 121 of the support assembly 12, thereby achieving precise control and efficient sliding of the support frame 121, thereby driving the movement of the massage member 13. The connection between the driving member 17 and the support frame 121 is usually carried out by a connecting rod or a direct connection, ensuring that the driving force of the driving member 17 can be effectively transmitted to the support frame 121, driving the support assembly 12 as a whole to slide along the chair frame 20. This design not only ensures the stability of the sliding process, but also enhances the uniformity of the force applied to the support frame 121.

[0059] The drive member 17 can be in the form of an electric screw, a common linear actuator. The electric screw drives the screw nut along the screw's axis through the rotation of the motor, thereby converting rotational motion into linear motion. This ensures that the support frame 121 can achieve smooth and controllable sliding under the drive member 17, thereby driving the massage member 13 to accurately position and move on the back of the human body. The precise control capability of the electric screw allows the massage member 13 to be flexibly adjusted to meet the massage needs of different users.

[0060] Another aspect of the present application provides a massage chair. Figure 4 As shown, the massage chair includes a chair frame 20 and any of the above-mentioned movable sealing structures 10, wherein the cloak 11 of the movable sealing structure 10 is mounted on the chair frame 20, and the support assembly 12 of the movable sealing structure 10 is slidably connected to the chair frame 20. Since the massage chair adopts any of the above-mentioned movable sealing structures 10, it also has the same beneficial effects. For details, please refer to the previous description and will not be repeated here.

[0061] Optionally, the massage chair further includes a backrest 30 , and the cloak 11 of the movable sealing structure 10 is mounted on the chair frame 20 via the backrest 30 .

[0062] Specifically, if Figure 4 As shown, the design of the backrest 30 provides a more stable support for the movable sealing structure 10. The cloak 11 is connected to the chair frame 20 through the backrest 30, ensuring that the movable sealing structure 10 can remain stable during operation. In addition, the presence of the backrest 30 makes the cloak 11 more flat during installation, reducing the discomfort during massage caused by the unevenness or looseness of the cloak 11. It should be noted that the backrest 30 is mainly made of plastic material, and the cloak 11 is mainly made of cloth or leather material. The cloak 11 can be tightly connected to the backrest 30 by glue, nail gun, buttonhole hanging, sewing, snap fasteners or other mechanical connection methods, thereby enhancing the protective function.

[0063] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
