Detailed Implementation

[0020] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0022] The embodiments described in this specification will now be described in detail.

[0023] Reference Figure 1 As shown, this application discloses a massage backrest, which includes a backrest body 10 and a massage mechanism disposed within the backrest body 10. The massage mechanism includes a linkage rail 20, a control box 30, a massage head 40, a guide rail 50, a controller 60, and a power supply 70. Thus, when a user rests against the massage backrest, the massage mechanism within the backrest body 10 can effectively relieve back fatigue and enhance user comfort.

[0024] To facilitate understanding of the internal structure of the backrest body 10 Figure 2 Only the side of the backrest body 10 away from the human body is shown when the user rests against the massage backrest; the other part can be fixed to the part shown in the figure by means of screws, buckles, etc.

[0025] The inner wall of the backrest body 10 is provided with two positioning plates 11 extending to opposite ends, forming a limiting groove between the two positioning plates 11 to position the linkage rail 20 and guide rail 50 on the backrest body 10. Furthermore, to improve installation stability, a mounting post 12 is provided between the two positioning plates 11, and the mounting post 12 has threaded mounting holes for fixing to the linkage rail 20 and guide rail 50.

[0026] In this embodiment, the positioning plate 11 extends vertically, i.e., along the height of the massage backrest. In another embodiment, the positioning plate 11 can also extend horizontally. In yet another embodiment, the positioning plate 11 can extend both vertically and horizontally, with the linkage rails 20 in the corresponding two directions arranged vertically along the thickness of the backrest body 10 to avoid interference. Alternatively, the linkage rails 20 in the two directions can be interconnected, forming a cross-shaped structure. Specific adjustments can be made based on the massage position, and are not limited here.

[0027] The inner wall of the backrest body 10 is provided with multiple limiting blocks 13, which are respectively arranged in an arc shape towards the linkage rail 20 and the guide rail 50.

[0028] Specifically, the linkage track 20 and guide track 50 are made of plastic, which gives them a certain degree of elastic deformation. When the user leans back, the body weight is transmitted through the massage head 40 to the control box 30, and then from the control box 30 to the linkage track 20 and guide track 50. At this time, the plastic track can undergo slight bending that conforms to the body's back, providing a soft support and avoiding the discomfort caused by hard impacts.

[0029] However, to prevent the control box 30 from exceeding its elastic limit under long-term or excessive loads and undergoing permanent bending or fatigue damage, this application provides a limiting block 13 on the inner wall of the backrest body 10 corresponding to the easily deformable position of the track. These limiting blocks 13 are precisely calculated so that their arc-shaped concave surfaces maintain a small gap with the contour of the track in its natural state. This gap size ensures that the track can bend normally within a safe and comfortable range. Once the track's deformation under pressure approaches a critical value, its surface contacts and abuts against the arc-shaped support surface of the limiting block 13, thereby preventing further bending of the track through hard contact.

[0030] In this way, users can enjoy flexible support that conforms to their body shape during daily use, significantly improving comfort. At the same time, the limiting block 13 acts as a "safety barrier," effectively preventing the track from plastically deforming or breaking due to overload, greatly enhancing the reliability and service life of the massage mechanism.

[0031] Please refer to the reference again. Figure 3 As shown, the linkage track 20 has a toothed groove 21 on its side along its length, and the control box 30 has a gear (not shown in the figure) that rotatably engages with the toothed groove 21. Specifically, combined with Figure 4 As shown, the linkage rail 20 passes through the control box 30, and the control box 30 has a groove for accommodating the gear. The groove is connected to the linkage rail 20 in the area through which the control box 30 passes, thus realizing the meshing of the gear and the tooth groove 21. When the gear rotates, it drives the control box 30 to move along the length of the linkage rail 20.

[0032] The upper surface of the linkage track 20 is provided with multiple grooves 22, which are spaced apart along the length of the linkage track 20 to reduce the weight of the guide track 50 and facilitate manufacturing.

[0033] Please refer to the reference again. Figure 5 As shown, the control box 30 adopts a split structure, with the upper box 31 and the lower box 32 detachably fixedly connected by snaps or screws. The linkage rail 20 and the guide rail 50 are parallel to each other and pass through a specially designed through cavity inside the lower box 32.

[0034] The drive gear and its transmission mechanism are housed within the lower housing 32 and maintain stable engagement with the toothed grooves 21 of the linkage track 20. The upper housing 31 primarily houses the drive motor and control circuitry of the massage head 40. This layout achieves spatial integration and partitioned management of the power transmission module and the function execution module.

[0035] The massage head 40 is mounted on the control box 30 and located on the side of the massage backrest used to support the human body. In this embodiment, the massage head 40 is rotatably mounted on the control box 30. Specifically, the massage head 40 is driven by a micro motor inside the control box 30 to perform rotation, vibration, or kneading movements, simulating the massage techniques of a human hand, thereby realizing various complex massage modes such as "wave massage" and "fixed-point deep massage," greatly enhancing the user experience.

[0036] Reference Figure 6 As shown, the massage head 40 includes three massage points 41a, 41b, and 41c, with massage point 41a being the highest. Massage point 41b is the second highest and is positioned opposite massage point 41a. Massage point 41c is the lowest, and there are two of them, arranged on either side of massage points 41a and 41b.

[0037] In another embodiment, the number of massage heads 40 can be set to two, four or more, which can be adjusted according to the massage points, massage intensity and other aspects, and no specific limitation is made here.

[0038] Please refer to the reference again. Figure 7 As shown, the guide rail 50 passes through the control box 30 and is fixed to the backrest body 10. In this embodiment, the guide rail 50 and the linkage rail 20 are arranged parallel to each other. The parallel design of the two rails greatly enhances the rigidity and stability of the control box 30 during movement, eliminates the "stuttering" or "lifting" phenomenon caused by unilateral force, ensures a smooth, quiet, and stable massage process, and improves the overall quality and reliability of the product. In this embodiment, the guide rail 50 includes a main body 51 and a positioning part 52. The positioning part 52 protrudes partially upward from the upper surface of the main body 51 and together with the upper surface of the main body 51, forms a stepped portion. This allows for rapid and precise positioning and installation of the components that mate with the guide rail 50 and the control box 30, effectively preventing assembly misalignment and significantly improving assembly efficiency and the stability of the connection structure.

[0039] The upper surface of the guide rail 50 is provided with a plurality of grooves 53, which are spaced apart along the length of the guide rail 50 to reduce the weight of the guide rail 50 and facilitate manufacturing.

[0040] The controller 60 is located outside the backrest body 10 and connected to the backrest body 10. The controller 60 is equipped with control switches, mode switches, time switches, etc. The controller 60 can be connected to the backrest body 10 via wired or wireless means. When the controller 60 is a wireless controller, it can be a remote control or a mobile APP, and has a variety of preset massage programs built in. The program can control the movement path, speed, intensity, and combination and duration of the massage head 40.

[0041] The power supply 70 is located inside the backrest body 10 and connected to the controller 60. In one embodiment, charging is performed via a charging port located on the side wall or bottom of the backrest body 10, thus allowing the massage backrest to be used completely without cables, achieving wireless operation and greatly improving the product's portability and versatility.

[0042] In another embodiment, the power supply 70 can also be a power supply 70 module, which is connected to the external power supply via a power supply 70 line that runs through the backrest body 10, making it suitable for long-term, high-intensity, and stable use scenarios.

[0043] This application also discloses a seating arrangement including a massage cushion. Examples include office chairs, lounge sofas, car seats, or cinema seats. In one embodiment, the massage cushion is an integral part of the seating arrangement, with its backrest body 10 fixedly connected to the frame of the seating arrangement.

[0044] In another embodiment, the massage cushion can also be a freestanding, detachable component. For example, it can be temporarily attached to the back of an existing seat using straps, hooks, or Velcro. Alternatively, it can be a standalone massage cushion with a complete support structure, which can be placed on any chair for use.

[0045] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
