Abstract
Description
Technical Field
[0001] The present application relates to the technical field of massage devices, and in particular to a massage movement and a massage chair. Background Art
[0002] The massage movement is mounted on the massage chair rails via rolling wheels. In order for the massage movement to operate stably in the massage chair rails, the rolling wheels and the massage chair rails need to meet certain matching requirements. Since the rails are slender components and serve as part of the massage chair frame, they need to bear the weight of the human body. Therefore, they are prone to twisting and deformation during use, causing the lateral dimensions of the rails on both sides to change, resulting in a gap or abutment between the movement rolling wheels and the massage chair rails. When the massage chair is in use, the massage movement needs to move back and forth on the massage chair rails for a long time. Once the lateral dimensions of the rails on both sides are larger than the assembly dimensions of the massage movement, a gap will be generated between the rails and the rolling wheels, causing the massage movement to shake left and right, resulting in reduced structural stability. Another possibility is that the lateral dimensions of the rails on both sides are smaller than the assembly dimensions of the massage movement, causing the rolling wheels to collide and rub against the inner wall of the rails, producing abnormal noise, which is not conducive to the smooth operation of the massage movement. Utility Model Content

[0025] 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.
[0026] The massage mechanism is mounted on the massage chair rails 103 via rollers 102. To ensure stable operation within the rails, the rollers 102 and rails must meet certain requirements. Because the rails are elongated components that form part of the massage chair frame and bear the weight of the user, they are susceptible to twisting and deformation during use, causing the lateral dimensions of the rails to change, leading to gaps or abutment between the rollers 102 and rails.
[0027] During use, the massage mechanism requires extended reciprocating motion along the massage chair rails 103. If the lateral dimensions of the rails are larger than the assembly dimensions of the massage mechanism, a gap will form between the rails and the rollers 102, causing the massage mechanism to wobble and reduce structural stability. Alternatively, if the lateral dimensions of the rails are smaller than the assembly dimensions of the massage mechanism, the rollers 102 will collide and rub against the inner walls of the rails, producing unusual noises and hindering the smooth operation of the massage mechanism.
[0028] In order to solve the above technical problems, the embodiments of the present application provide a massage movement and a massage chair.
[0029] Reference Figure 1 、 Figure 2 As shown, an embodiment of the present application provides a massage movement, which is configured on a massage chair guide rail 103. The massage movement includes a movement frame 100, a rotating shaft 101 and a rolling wheel 102; the rotating shaft 101 is installed on the movement frame 100, and the rolling wheel 102 is sleeved on both ends of the rotating shaft 101, and the rolling wheel 102 is driven to move along the path arranged on the massage chair guide rail 103; a first abutment portion 104 is provided on the movement frame 100, and a second abutment portion 105 is provided on the side of the rolling wheel 102; it also includes an elastic structural member 106 arranged between the first abutment portion 104 and the second abutment portion 105; the elastic structural member 106 is compressed along the axial direction of the rotating shaft 101 under force, and generates a force that causes the rolling wheel 102 to approach the massage chair guide rail 103 on the rotating shaft 101.
[0030] It should be noted that the massage chair guide rail 103 is a long, rectangular structure that needs to bear significant pressure. Currently, most massage chairs on the market feature fixed-size mechanisms and guide rails. Because of this fixed structure, the dimensional control and management of the components at the mating position is relatively high. Furthermore, the mating components are prone to deformation, especially the slender guide rails, which can easily cause large errors in lateral dimensional control and make it difficult to control. This can lead to gaps and left-right wobbling in the mechanism, and especially to friction interference and unusual noises in smaller mechanisms.
[0031] When the movement frame 100 moves back and forth on the massage chair guide rail 103, the massage chair guide rail 103 is prone to deformation and twisting. The degree of deformation and twisting is limited, and the distance between the two sides of the massage chair guide rail 103 will increase or decrease within a certain range.
[0032] When the distance between the two sides of the massage chair guide rail 103 becomes larger, the embodiment of the present application pushes the scroll wheel 102 to slide toward the side of the massage chair guide rail 103 on the rotating shaft 101 through the elastic structural member 106, thereby eliminating the gap caused by the increase in the distance between the two sides of the massage chair guide rail 103, and ensuring that the scroll wheel 102 can move on the massage chair guide rail 103 without lateral collision.
[0033] When the distance between the two sides of the massage chair guide rail 103 becomes smaller, the embodiment of the present application can cause the rolling wheel 102 to slide toward the side of the movement frame 100 through the contraction of the elastic structural member 106, thereby avoiding the distance friction between the rolling wheel 102 and the inner wall of the massage chair guide rail 103 due to the smaller distance between the two sides of the massage chair guide rail 103, and can effectively eliminate abnormal noise.
[0034] The embodiment of the present application can reduce the precision requirements of the transfer process of the massage chair guide rail 103 to a certain extent, so that the massage movement can have adaptive adjustment capabilities and avoid interference with the massage chair guide rail 103.
[0035] The embodiment of the present application provides a massage movement configured on a massage chair guide rail 103. The massage movement includes a movement frame 100, a rotating shaft 101, and a rolling wheel 102. The rotating shaft 101 of the embodiment of the present application is mounted on the movement frame 100, and the rolling wheel 102 is sleeved at both ends of the rotating shaft 101. The rolling wheel 102 is driven to move along the path arranged on the massage chair guide rail 103. The embodiment of the present application has a first abutting portion 104 provided on the movement frame 100, and a second abutting portion 105 provided on the side of the rolling wheel 102. The embodiment of the present application also has an elastic structural member 106 provided between the first abutting portion 104 and the second abutting portion 105.
[0036] The elastic structure 106 of the embodiment of the present application is compressed along the axis of the rotating shaft 101, and generates a force that causes the rolling wheel 102 to move closer to the massage chair guide rail 103 on the rotating shaft 101. The rolling wheel 102 of the embodiment of the present application is sleeved on the rotating shaft 101 and can slide in the axial direction.
[0037] When the massage chair guide rail 103 is deformed or twisted during long-term use, causing the distance between the massage chair guide rails 103 on both sides to change, matching adjustment is achieved through the axial sliding of the rolling wheel 102, wherein the elastic structural member 106 can generate a force that pushes the rolling wheel 102 to abut against the massage chair guide rail 103, ensuring that the rolling wheel 102 can roll stably on the massage chair guide rail 103.
[0038] Compared with the prior art, the embodiment of the present application can achieve adaptive adjustment of the position of the scroll wheel 102 through the provision of the elastic structural member 106, thereby preventing the massage movement from moving left and right and colliding and interfering with the guide rail.
[0039] Reference Figure 1 、 Figure 2As shown, as an optional embodiment, the rotating shaft 101 includes an intermediate shaft 107 and an end shaft 108.

[0040] It should be noted that the scroll wheel 102 of the embodiment of the present application is mounted on the end shaft 108 through the shaft hole, and the sliding range of the scroll wheel 102 is limited by the length of the end shaft 108. During adaptive adjustment, the scroll wheel 102 cannot escape the length of the end shaft 108.
[0041] As an optional embodiment, a rotating shaft 101 bearing is provided in the shaft hole of the rolling wheel 102 , and the rolling wheel 102 is sleeved on the end shaft 108 through the rotating shaft 101 bearing.
[0042] Furthermore, in the embodiment of the present application, a rotating shaft 101 bearing is provided in the shaft hole of the rolling wheel 102. The rotating shaft 101 bearing can avoid wear on the inner wall of the shaft hole, thereby improving the stability and reliability of the structure.
[0043] As an optional embodiment, the elastic structural member 106 includes a spring element sleeved on the rotating shaft 101 ; or, the elastic structural member 106 includes a metal spring arranged between the first abutting portion 104 and the second abutting portion 105 .
[0044] The elastic structure 106 in the embodiment of the present application can be a spring element, such as a cylindrical spring or a pagoda spring sleeved on the rotating shaft 101. The elastic structure 106 in the embodiment of the present application can also be a metal spring, which can be selected by those skilled in the art according to their needs.
[0045] As an optional embodiment, the first abutting portion 104 is a first gasket sleeved on the end shaft 108, and the first gasket is pushed by the elastic structure 106 to fit the side wall of the movement frame 100;
[0046] Another implementation method is to directly use the side wall of the movement frame 100 as the first abutting portion 104 .
[0047] The second abutting portion 105 is a second gasket sleeved on the end shaft 108 . The second gasket is pushed by the elastic structure 106 to fit the inner wall of the rolling wheel 102 close to the movement frame 100 .
[0048] As an optional embodiment, two rotating shafts 101 are provided on the movement frame 100; a massage head and a driving module 109 for driving the massage head to move are installed on the movement workshop between the two rotating shafts 101.
[0049] The drive module 109 further includes a transmission assembly connecting the drive module 109 and the rotating shaft 101 . The drive module 109 drives the rotating shaft 101 to rotate through the transmission assembly. The rotating shaft 101 is meshed with the scroll wheel 102 for transmission.
[0050] An embodiment of the present application provides a massage chair, comprising a massage chair frame and the above-mentioned massage movement; the massage chair frame is provided with massage chair guide rails 103 located on both sides of the massage movement, and the rolling wheels 102 of the massage movement are driven to move along the extension path of the massage chair guide rails 103.
[0051] The massage chair provided in the embodiment of the present application utilizes the aforementioned massage mechanism. The elastic structural member 106 is provided to adaptively adjust the position of the scroll wheel 102, preventing the massage mechanism from shifting sideways and interfering with the guide rails. Consequently, the embodiment of the present application can reduce the failure rate of the massage chair caused by deformation of the massage chair guide rails 103, effectively prevent abnormal noise, and improve the quietness and comfort of the massage chair during operation.
[0052] As an optional embodiment, a U-shaped groove is provided in the massage chair guide rail 103, and a hemispherical protrusion is provided on the side of the rolling wheel 102 facing away from the movement frame 100, which is in contact with the bottom of the U-shaped groove, for reducing the contact area between the rolling wheel 102 and the bottom of the U-shaped groove.
[0053] It should be noted that the embodiment of the present application can reduce the contact area between the rolling wheel 102 and the bottom of the U-shaped groove by arranging a hemispherical protrusion on the side of the roller wheel, thereby reducing the friction resistance generated by the elastic structural part 106 pushing the rolling wheel 102 and the massage chair guide rail 103, making it easier for the massage movement to move smoothly on the massage chair guide rail 103.
