Description

Technical Field

[0001] This utility model belongs to the field of massage chairs, and specifically relates to a massage chair. Background Technology

[0002] With the rapid development of technology, massage chairs have gradually become an important massage device for relaxing the whole body, whether in homes or public places.

[0003] Most existing massage chairs feature an adjustable backrest to allow users to achieve the optimal reclining posture for a massage. However, the armrests of most traditional massage chairs are fixed and cannot automatically adjust to changes in the user's posture. This means that after adjusting to a suitable reclining position, the fixed armrest position causes the arms to gradually move away from the armrests as the body moves. Consequently, the arms cannot properly enjoy the kneading function provided by the airbags inside the armrests. This not only affects the overall comfort of the massage chair but also prevents the user from fully relaxing during use, thus failing to achieve the desired massage effect. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a massage chair with a simple overall structure that can adaptively adjust the armrest body to massage the arm as the seat is tilted, thus ensuring the best massage experience.

[0005] The technical solution adopted by this utility model to solve its technical problem is to propose a massage chair with a seat back that can rotate relative to the seat body, including: an armrest support, and the seat body is provided with at least one of the armrest supports;

[0006] The armrest body is movably mounted on the armrest support, and the armrest body allows an arm to be inserted and repeatedly rubbed.

[0007] A damping element is connected to the bottom wall of the handrail body and extends into the handrail support. The damping element is used to control the speed of the handrail body when it moves relative to the handrail support.

[0008] When the seat back is tilted relative to the seat body due to external pressure, the arm can cause the armrest body to move relative to the armrest bracket due to friction, so that the armrest body always fits against the arm and rubs it back and forth.

[0009] In the aforementioned massage chair, the damping component includes:

[0010] A sliding seat is connected to the bottom wall of the handrail body;

[0011] A damping gear and a damping rack are provided. The damping gear is movably connected to the sliding seat, and the damping rack is installed in the handrail bracket along the moving direction of the handrail body. The damping gear and the damping rack are movably meshed.

[0012] In the massage chair described above, the bottom wall of the armrest body is provided with several locking blocks, and the armrest support is provided with locking holes. The locking blocks are movably engaged with the locking holes to limit the displacement of the armrest body relative to the armrest support.

[0013] In the massage chair described above, a guide groove is provided in the armrest support, and the sliding seat is movably engaged in the guide groove.

[0014] In the massage chair described above, the bottom wall of the guide groove is provided with an anti-detachment groove, an anti-detachment block is formed on the sliding seat, the damping rack is connected to one side of the anti-detachment groove, and the damping gear can be movably engaged with the damping rack when the anti-detachment block is movably extended into the anti-detachment groove.

[0015] In one of the massage chairs described above, the outer diameter of the damping gear is greater than the width of the anti-detachment block.

[0016] The technical solution adopted by this utility model to solve its technical problem is to also propose a massage chair, which has a seat back that can rotate relative to the seat body, including:

[0017] At least one armrest support is provided on the seat body;

[0018] The armrest body is movably mounted on the armrest support, and the armrest body allows an arm to be inserted and repeatedly rubbed.

[0019] A drive mechanism is provided inside the handrail bracket, and the output end of the drive mechanism is connected to the handrail body to drive the handrail body to move relative to the handrail bracket.

[0020] When the seat backrest is tilted relative to the seat body due to external pressure, the drive mechanism can drive the armrest body to move relative to the armrest bracket and closer to the seat backrest, so that the armrest body is always in contact with the arm and can be repeatedly rubbed.

[0021] In the massage chair described above, the drive mechanism includes a drive motor and a movable block. The drive motor is installed inside the armrest bracket, and a rotating rod is connected to the drive end of the drive motor. The movable block is connected to the armrest body and is movably sleeved on the rotating rod.

[0022] The technical solution adopted by this utility model to solve its technical problem is to also propose a massage chair, which has a seat back that can rotate relative to the seat body, including:

[0023] At least one armrest support is provided on the seat body;

[0024] The armrest body is movably mounted on the armrest support, and the armrest body allows an arm to be inserted and repeatedly rubbed.

[0025] A linkage mechanism, one end of which is movably connected to the seat back and the other end of which is movably connected to the armrest body;

[0026] When the seat back is leaned against, the linkage mechanism can simultaneously drive the armrest body to move relative to the armrest bracket when the seat back is tilted relative to the seat body, so that the armrest body is always in contact with the arm and can reciprocate to rub it.

[0027] In the massage chair described above, the linkage mechanism includes a linkage rod and a movable rod. The two ends of the linkage rod are respectively provided with a first connecting hole and a second connecting hole. A fixed rod is provided on the side wall of the armrest body. The fixed rod is movably connected to the first connecting hole. One end of the movable rod is hinged to the seat back, and the other end is movably connected to the second connecting hole.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) This utility model provides a massage chair that, by setting up a damping component / drive mechanism / linkage mechanism, allows the user to lean against the seat back and tilt it, and rely on the adaptive sliding adjustment function of the armrest body relative to the armrest support to ensure that the airbags in the armrest body can always fit the arm and rub and massage it. The overall structure is simple, ensuring that the user can get the best massage experience no matter how the posture changes, enhancing the comfort and providing a guarantee for achieving the massage effect required by the user.

[0030] (2) By utilizing the sliding of the sliding seat in the guide groove, the smoothness and stability of the armrest body in the reciprocating sliding process relative to the armrest support are ensured; at the same time, the movement of the anti-detachment block in the anti-detachment groove ensures that the damping gear can stably mesh with the damping rack. Under the dual guiding mechanism, the stability of the armrest body in the movement of the armrest body and the massage is greatly improved, effectively avoiding the impact of shaking or tilting on the smoothness and comfort of the massage process.

[0031] (3) The combination of locking blocks and locking holes allows the armrest body to be precisely fixed in a specific position, ensuring the accuracy of each contact point during the massage process and improving the massage effect; at the same time, multiple locking blocks can select appropriate locking points according to different needs, further increasing the flexibility and adaptability of the massage chair.

[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0046] Example 1:

[0047] like Figures 1 to 6 As shown, this utility model discloses a massage chair with a seat back 10 that can rotate relative to the seat body 1, including: an armrest support 2, an armrest body 3, and a damping component 4. At least one armrest support 2 is provided on the seat body 1; the armrest body 3 is movably mounted on the armrest support 2 and allows an arm to be inserted for reciprocating massage; the damping component 4 is connected to the bottom wall of the armrest body 3 and extends into the armrest support 2, and is used to control the speed at which the armrest body 3 moves relative to the armrest support 2; when the seat back 10 is tilted relative to the seat body 1 under external pressure, the arm can be displaced relative to the armrest support 2 due to friction, so that the armrest body 3 always fits against the arm for reciprocating massage.

[0048] Specifically, such as Figures 1 to 4 As shown, when a user sits on the massage chair and places their arms on the armrest, the built-in massage airbags (not shown in the figure) in the armrest can perform a kneading motion on the arms. At the same time, the airbags inside the seat back 10 also perform the required massage operation on the user's back after being opened. However, during the process of the seat back 10 rotating relative to the seat body 1 and tilting backward, for traditional massage chairs, since the armrest body 3 is fixedly set on the armrest support 2, coupled with the user's backward operation with the seat back 10, the arms cannot reach the armrest body, and ultimately the arms cannot properly enjoy the kneading motion provided by the massage airbags when they are detached from the armrest body. For the massage chair of this application, the armrest body 3 is movably set on the armrest support 2. This also allows the user to lean back or lean forward. Due to the certain friction between the user's arms and the armrest body 3, the friction, in conjunction with the damping component 4, can drive the armrest body 3 to slide relative to the armrest support 2. This ensures that as the user's posture changes, the armrest body (with massage airbags) can simultaneously change its position to perform a kneading motion on the arms. As can be seen, this design allows the armrest body 3 to automatically adjust its position according to the user's different sitting postures. This enables the massage chair to not only provide basic back massage but also effectively cater to the user's arms, ensuring a close fit to the arms at all times and providing a personalized massage experience. The damping element 4 precisely controls the movement speed of the armrest body 3, avoiding discomfort that might be caused by excessive speed while ensuring sufficient massage intensity and enhancing the overall user experience.

[0049] The damping component 4 includes: a sliding seat 40 connected to the bottom wall of the handrail body 3; a damping gear 41 and a damping rack 42, wherein the damping gear 41 is movably connected to the sliding seat 40, and the damping rack 42 is installed in the handrail bracket 2 along the moving direction of the handrail body 3, and the damping gear 41 and the damping rack 42 are movably meshed.

[0050] Furthermore, such as Figures 2 to 4 As shown, in this embodiment, the sliding seat 40 is detachably connected to the bottom wall of the armrest body 3. A mounting plate 401 is also detachably connected to the bottom wall of the sliding seat 40 near the armrest support 2. The damping gear 41 is movably mounted on the mounting plate 401, facilitating the engagement between the damping gear 41 and the damping rack 42, and providing convenience for subsequent maintenance and replacement. During the movement of the armrest body 3 relative to the armrest support 2 driven by the friction of the user's arm, the cooperation of the damping gear 41 and the damping rack 42 ensures good stability and smoothness during movement, reducing unnecessary vibration and noise, improving overall operational comfort, and providing a more comfortable user experience. Furthermore, the reasonable damping design can reduce mechanical wear caused by rapid movement or sudden stops, thereby extending the service life of the massage chair.

[0051] Preferably, such as Figure 3 and Figure 4 As shown, this embodiment also provides mounting holes 402 on the sliding seat 40 and the mounting plate 401. The mounting holes 402 can be fixed to a designated position (e.g., armrest body 3, sliding seat 40, etc.) by bolts, screws and other connecting parts, so as to ensure that the mounting plate 401 and the sliding seat 40 can remain stationary with respect to the armrest body 3 during the movement of the armrest body 3 relative to the armrest bracket 2, effectively improving the stability of the overall structure of the massage chair.

[0052] More preferably, such as Figure 4 As shown, this embodiment also includes a guide groove 21 within the handrail bracket 2. During the sliding process of the handrail body 3 relative to the handrail bracket 2, the sliding seat 40 is movably engaged within the guide groove 21, ensuring that the sliding seat 40 can only slide in a predetermined direction (i.e., Figure 4 The guide groove 21 moves along its length, preventing the handrail body 3 from shifting or misaligning during adjustment, thus improving overall stability and reliability.

[0053] The bottom wall of the guide groove 21 is provided with an anti-detachment groove 210, and an anti-detachment block 400 is formed on the sliding seat 40. The damping rack 42 is connected to one side of the anti-detachment groove 210. The damping gear 41 can be moved and engaged with the damping rack 42 when the anti-detachment block 400 is moved into the anti-detachment groove 210.

[0054] More preferably, such as Figure 3 and Figure 4 As shown, during installation, the anti-detachment block 400 extends into the anti-detachment groove 210, ensuring the accuracy of the sliding seat 40's engagement with the guide groove 21 and the meshing of the damping gear 41 and damping rack 42. This effectively prevents the sliding seat 40 from accidentally falling out of the guide groove 21 during use and reduces offset or misalignment caused by external forces, ensuring that the armrest body 3 is always in the correct posture for position adjustment. Therefore, the engagement of the sliding seat 40 with the guide groove 21, combined with the movement of the anti-detachment block 400 within the anti-detachment groove 210, ensures that the damping gear 41 can stably mesh with the damping rack 42. This dual guiding mechanism greatly improves the stability of the armrest body 3 during movement and massage, effectively preventing wobbling or tilting from affecting the smoothness and comfort of the massage process.

[0055] More preferably, in this embodiment, the outer diameter of the damping gear 41 is greater than the width of the anti-detachment block 400. This design ensures that the damping gear 41 maintains good contact with the damping rack 42 throughout the entire movement, reducing unnecessary friction and wear. This not only improves the service life of the massage chair but also reduces maintenance costs.

[0056] The bottom wall of the handrail body 3 is also provided with several locking blocks 30, and the handrail support 2 is provided with locking holes 20. The locking blocks 30 are movably engaged with the locking holes 20 to limit the displacement of the handrail body 3 relative to the handrail support 2.

[0057] More preferably, such as Figure 2 and Figure 4 As shown, when the arm moves the handrail body relative to the handrail support 2 by friction (or by manual pulling), the locking block 30 can be engaged in the locking hole 20 after the handrail body 3 reaches the designated position. It should be noted that the number of locking blocks 30 and locking holes 20 in this embodiment is one-to-one. They can be set at the extreme positions of the handrail body 3 during movement, or designed for specific positions. Furthermore, the contact end between the locking block 30 and the handrail support 2 is spherical to reduce friction and wear. In other words, users can flexibly adjust the position of the handrail body 3 according to their needs, and it can be quickly locked after adjustment, meeting the personalized needs of different users, avoiding unexpected displacement caused by external forces, and improving the stability and safety of use.

[0058] Example 2:

[0059] This second embodiment replaces the movement method of the armrest body 3 in the first embodiment above, and proposes a massage chair with a seat back 10 that can rotate relative to the seat body 1, including: an armrest support 2, at least one armrest support 2 is provided on the seat body 1; an armrest body 3, movably disposed on the armrest support 2, the armrest body 3 allowing an arm to be inserted and reciprocated for kneading; a drive mechanism 5, disposed inside the armrest support 2, the output end of the drive mechanism 5 being connected to the armrest body 3 to drive the armrest body 3 to move relative to the armrest support 2; when the seat back 10 is tilted relative to the seat body 1 due to external pressure, the drive mechanism 5 can drive the armrest body 3 to move relative to the armrest support 2 and approach the seat back 10, so that the armrest body 3 is always in contact with the arm and reciprocated for kneading.

[0060] Similarly, when a user sits on the massage chair and places their arms on the armrest, as the user leans back on the seat back 10, the drive mechanism 5 can simultaneously drive the armrest body 3 to move as the seat back 10 leans back or forward. In other words, the drive mechanism 5 in this embodiment 2 automatically starts by sensing the angle change of the seat back 10 and adjusts the position of the armrest body 3 according to sensor feedback. The whole process does not require manual intervention, reducing the risk of misoperation, and also ensuring that the armrest body 3 always fits the user's arms, thus ensuring the smoothness and comfort of the entire massage process.

[0061] The drive mechanism 5 includes a drive motor 50 and a movable block 51. The drive motor 50 is installed inside the handrail bracket 2, and a rotating rod 52 is connected to the drive end of the drive motor 50. The movable block 51 is connected to the handrail body 3 and is movably sleeved on the rotating rod 52.

[0062] Furthermore, such as Figure 5 As shown, in this embodiment two, the drive motor 50 can be fixed inside the armrest bracket 2 by bolts, screws, or other fasteners. It is worth noting that the length direction of the rotating rod 52 connected to the output end of the drive motor 50 is parallel to the direction in which the armrest body 3 is to reciprocate. This allows the drive motor 50 to activate immediately after receiving a signal indicating the seat back 10's tilt angle adjustment, driving the rotating rod 52 to rotate. This, in turn, moves the movable block 51 along the length direction of the rotating rod 52, ultimately achieving precise control of the armrest body 3's position. The entire process requires no complex steps or tools, greatly improving operational convenience. Preferably, the working principle of the rotating rod 52 and the movable block 51 in this embodiment two can be referenced from commonly used ball screws in machinery, and will not be elaborated further here.

[0063] Example 3:

[0064] This third embodiment replaces the movement method of the armrest body 3 in the first and second embodiments above, and also provides a massage chair with a seat back 10 that can rotate relative to the seat body 1, including: an armrest support 2, at least one armrest support 2 is provided on the seat body 1; an armrest body 3, movably disposed on the armrest support 2, the armrest body 3 allows an arm to be inserted and reciprocated for kneading; a linkage mechanism 6, one end of the linkage mechanism 6 is movably connected to the seat back 10, and the other end is movably connected to the armrest body 3; when the seat back 10 is leaned against, the linkage mechanism 6 can simultaneously drive the armrest body 3 to move relative to the armrest support 2 when the seat back 10 is tilted relative to the seat body 1, so that the armrest body 3 always fits against the arm and reciprocates for kneading.

[0065] Specifically, such as Figure 6 As shown, when a user sits on the massage chair and places their arms on the armrests, the linkage mechanism 6, whose two ends are movably connected to the armrest body 3 and the seat back 10 respectively, applies a certain pulling force to the armrest body 3 as the user leans back on the seat back 10. This means the movement of the seat back 10 is directly transmitted to the armrest body 3 via the linkage mechanism 6. This synchronized movement ensures that the armrest body 3 always conforms to the user's arms, regardless of the user's posture. This not only improves the functionality of the massage chair but also significantly enhances the user experience, providing continuous support and massage effects. Compared to the electric drive in Embodiment 2, the design of this linkage mechanism 6 simplifies the mechanical structure, reduces the number of complex parts, lowers manufacturing costs and maintenance difficulty, and also improves the overall reliability and durability of the massage chair, extending its service life.

[0066] The linkage mechanism 6 includes a linkage rod 60 and a movable rod 61. The two ends of the linkage rod 60 are respectively provided with a first connecting hole 600 and a second connecting hole 601. The side wall of the armrest body 3 is provided with a fixed rod 31, which is movably connected to the first connecting hole 600. One end of the movable rod 61 is hinged to the seat back 10, and the other end is movably connected to the second connecting hole 601.

[0067] Furthermore, such as Figure 6 As shown, the movable rod 61 and the fixed rod 31 are respectively hinged to the second connecting hole 601 and the first connecting hole 600. In addition, the movable rod 61 and the fixed rod 31 are distributed on both sides of the linkage rod 60, thereby ensuring that the tilt adjustment of the seat back 10 and the position adjustment of the armrest body 3 do not interfere with each other. Moreover, the hinged connection means that the tilt of the seat back 10 can be accurately converted into the sliding of the armrest body 3 relative to the armrest bracket 2, ensuring the synchronization between the two. The structure of this embodiment reduces the user's waiting time for the armrest body 3, reduces the overall manufacturing cost of the massage chair, and ensures the user's massage experience.
