Description

Technical Field

[0001] This utility model relates to the field of massage technology, and in particular to a massage chair armrest mechanism and a massage chair. Background Technology

[0002] Traditional massage chairs typically use fixed armrests, whose position remains unchanged during backrest angle adjustments. When a user reclines, their torso moves backward, and their arms naturally slide backward as well. However, the fixed armrests cannot move in sync, causing the arms to detach or become misaligned, failing to provide effective support and severely impacting user comfort.

[0003] Especially in structures where massage components (such as vibration motors, airbags, rollers, or electrical stimulation modules) are integrated into the armrests, the relative position of the massage components and the user's arms shifts significantly after the chair back is tilted due to the fixed position of the armrests. This causes the massage area to be unable to accurately align with the shoulder, elbow, or forearm muscle groups, resulting in uneven distribution of massage force, deviation of the point of application, attenuation of stimulation intensity, and even problems such as insufficient massage. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a massage chair armrest mechanism and a massage chair. Through the rotatable design of the armrest, the armrest can be adjusted to a tilted state when the chair back is tilted, so that the armrest and the user's arm can maintain effective cooperation.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a massage chair armrest mechanism, including an armrest and a driving component. The armrest is rotatably connected to the side support structure of the massage chair, and the rotation axis of the armrest extends along the left and right direction of the massage chair. The driving component is installed on the side support structure and is connected to the armrest for transmission, and is used to drive the armrest to rotate around its rotation axis so that the armrest switches between a folded state and a tilted state. The tilted state is that the front end of the armrest is raised relative to the folded state to form a tilt angle suitable for arm support.

[0006] In a preferred embodiment, the handrail includes a handrail body and a swing arm disposed at the rear end of the handrail body and extending rearward. The rear end of the handrail body or the front end of the swing arm is rotatably connected to the side support structure so that the handrail can rotate about its rotation axis. The drive component is drivenly connected to the swing arm.

[0007] In a preferred embodiment, a guide structure is provided between the swing arm and the side support structure to guide the swing arm to make circular motion around the rotation axis.

[0008] In a preferred embodiment, the guide structure includes a guide rod disposed on the swing arm and extending downward, and an arc-shaped guide rail disposed on the side support structure. The arc-shaped guide rail extends along the circumferential motion trajectory of the swing arm, and the free end of the guide rod is slidably engaged within the arc-shaped guide rail.

[0009] In a preferred embodiment, the driving component is an electric actuator, the connecting end of which is hinged to the side support structure, and the output end of which is hinged to the rear end of the swing arm, for providing linear thrust to drive the swing arm to rotate.

[0010] In a preferred embodiment, the armrest body is provided with a through arm receiving groove, and the inner sidewall of the arm receiving groove is provided with an opening so that the user's arm can enter the arm receiving groove through the opening.

[0011] In a preferred embodiment, the inner wall of the arm receiving slot is provided with a massage component, which is used to massage the user's arm placed in the arm receiving slot.

[0012] In a preferred embodiment, the side support structure includes a side plate and a rigid support frame mounted on the inner side of the side plate, the handrail is rotatably connected to the support frame, and the drive component is mounted on the support frame.

[0013] This utility model also provides a massage chair, including a chair frame, with side support structures on the left and right sides of the chair frame; at least one side support structure is provided with the massage chair armrest mechanism as described in this utility model.

[0014] In a preferred embodiment, the chair frame includes a backrest that can be flipped back and forth, and when the backrest is in a reclining state, the armrests can be adjusted to a tilted state to accommodate the user's leaning posture.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model rotatably connects the armrest to the side support structure, with the axis of rotation extending in the left-right direction. A drive component installed on the side support structure drives the armrest to rotate around the axis, enabling it to switch between a folded state and a tilted state with the front end raised. This design solves the problem that traditional fixed armrests cannot adapt to different sitting postures, allowing users to obtain stable and ergonomic support for their arms in a sitting or semi-reclining position, significantly improving comfort and user experience.

[0017] 2. Preferably, the handrail includes a handrail body and a rear-end extending swing arm, and the rear end of the handrail body or the front end of the swing arm is rotatably connected to the side support structure. The driving component drives the handrail body to rotate synchronously through the driving swing arm. This structure avoids arranging complex transmission components in the handrail body, making the handrail structure lighter and more compact, while improving motion stability and reliability and reducing the failure rate.

[0018] 3. Preferably, a guide structure is provided between the swing arm and the side support structure to guide the swing arm to perform circular motion around the rotation axis. This guide structure effectively limits the swaying and deviation during the rotation of the handrail, making the motion trajectory controllable, smooth, and free from jamming, thus improving the reliability and durability of the handrail mechanism for long-term use. In particular, the guide structure includes a guide rod provided on the swing arm and extending downward, and an arc-shaped guide rail provided on the side support structure. The arc-shaped guide rail extends along the circular motion trajectory of the swing arm, and the free end of the guide rod slides within the arc-shaped guide rail. This structure makes the guide structure design simple and compact, and provides precise guidance and stable operation.

[0019] 4. Because the backrest of the massage chair can be flipped back and forth, and when the backrest is flipped back to the inverted position, the armrests will automatically adjust to the tilt position to adapt to the user's leaning posture.

[0020] 5. The armrest mechanism of this utility model is integrated into the side support structure, with a reasonable overall layout, convenient installation, low maintenance cost, and no occupation of the internal space of the chair frame.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the massage chair armrest mechanism and massage chair of the present invention are not limited to the embodiments. Attached Figure Description

Detailed Implementation

[0026] In this utility model, the use of terms such as "upper," "lower," "left," "right," "front," "rear," "inner," "outer," and "top / bottom" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings and is only for the convenience of describing this utility model. It does not indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] Please see Figures 1-3 As shown, this utility model discloses a massage chair armrest mechanism, including an armrest 1 and a drive component. The armrest 1 is rotatably connected to the side support structure of the massage chair, and the rotation axis of the armrest 1 extends along the left-right direction of the massage chair. The drive component is installed on the side support structure and is connected to the armrest 1 for transmission, and is used to drive the armrest 1 to rotate around its rotation axis, so that the armrest 1 switches between a folded state A and a tilted state B. In the tilted state B, the front end of the armrest 1 is raised relative to the folded state A, forming an tilt angle suitable for the user's arm to rest and support naturally, so that the arm can obtain stable support when sitting or reclining, avoiding suspension or pressure, and significantly improving comfort.

[0028] In a preferred embodiment, the armrest 1 includes an armrest body 11 for resting the arm and a swing arm 12 located at the rear end of the armrest body 11 and extending rearward. The front end of the swing arm 12 is rotatably connected to a side support structure via a rotating shaft, so that the armrest 1 as a whole can rotate about its rotation axis. The drive component is connected to the swing arm 12 for transmission, rather than acting directly on the armrest body 11. This allows the drive mechanism, as well as the part of the armrest 1 connected to the drive mechanism (i.e., the swing arm 12), to be concentrated inside the massage chair, making the armrest body 11 thinner and more aesthetically pleasing, while reducing motion inertia and improving rotational stability.

[0029] Furthermore, a guide structure is provided between the swing arm 12 and the side support structure to guide the swing arm 12 to make circular motion around the rotation axis. This guide structure effectively limits the lateral swaying and offset of the handrail 1 during rotation, ensuring a stable and controllable motion trajectory, avoiding jamming or abnormal noise, and improving the reliability and durability of long-term use.

[0030] In this embodiment, the guiding structure includes a guide rod 13 disposed on the swing arm 12 and extending downward, and an arc-shaped guide rail 3 disposed on the side support structure. The arc-shaped guide rail 3 extends along the circumferential motion trajectory of the swing arm 12, and the free end of the guide rod 13 slides within the arc-shaped guide rail 3. This structure achieves high-precision trajectory constraint through the sliding engagement of the guide rod 13 and the guide rail, ensuring smooth and vibration-free movement of the handrail 1 when switching between the retracted and tilted states B. Furthermore, the structure is compact and easily integrated into a limited space.

[0031] In this embodiment, the driving component is preferably an electric push rod 2. The connecting end of the electric push rod 2 is hinged to the side support structure, and the output end of the electric push rod 2 is hinged to the rear end of the swing arm 12. It is used to provide linear thrust to drive the swing arm 12 to rotate, thereby causing the armrest body 11 to switch between the folded state A and the tilted state B. This utility model achieves efficient conversion from linear to rotational motion through the coordinated linear motion of the electric push rod 2 and the lever structure of the swing arm 12. It has the advantages of precise control, rapid response, low energy consumption, compact structure, and reliable operation, and is particularly suitable for the long-term high-frequency use of massage chairs. In other embodiments, the driving component can be implemented by a motor in conjunction with transmission components (such as gears, connecting rods, or synchronous belts) to provide rotational driving force to directly drive the swing arm 12 or the armrest body 11, meeting different structural layouts and control requirements.

[0032] The armrest body 11 has a through-type arm receiving groove 111. The inner wall of the arm receiving groove 111 has an opening, the size of which is adapted to the contour of an adult forearm, so that the user can naturally insert his arm through the opening and place it in the arm receiving groove 111 when seated, achieving a tight fit between the arm and the armrest body 11. Furthermore, the inner wall of the arm receiving groove 111 is provided with a massage component (such as a vibration motor, airbag, or electrical stimulation module) for massaging the user's hand and arm placed in the arm receiving groove 111. Since the arm is still accurately positioned in the receiving groove even in the tilted state B, the massage component can always act on the user's arm, solving the problems of inaccurate massage and weakened force caused by arm position displacement in traditional fixed armrests 1, and significantly improving the accuracy and comfort of the massage.

[0033] The side support structure includes a side plate 4 and a rigid support frame 5 mounted on the inner side of the side plate 4 (i.e., the surface facing the user's torso). The support frame 5 is preferably made of metal, such as iron, to provide sufficient structural rigidity and load-bearing capacity. The handrail 1 is rotatably connected to the top of the support frame 5 via the front end of its swing arm 12, forming a rotation axis extending in the left-right direction. A drive component (such as an electric actuator 2) is also mounted on the support frame 5. Specifically, the connecting end of the electric actuator 2 faces forward and is hinged to a mounting seat at the bottom front end of the support frame 5; the output end of the electric actuator 2 extends rearward and is hinged to the rear end of the swing arm 12. This structure integrates all moving parts into the rigid support frame 5, which not only improves the overall structural strength and stability but also facilitates modular assembly and maintenance, reducing overall manufacturing costs. The arc-shaped guide rail 3 is fixedly mounted on the inner side of the side plate 4 via a fixing seat 41. The fixing seat 41 is integrally formed with the side plate 4 or detachably connected to ensure that the arc-shaped guide rail 3 remains stably positioned during the movement of the handrail 1. Specifically, the two ends of the arc-shaped guide rail 3 are provided with lugs, and each lug is provided with a mounting hole. The mounting hole is fixedly connected to the fixing seat 41 by fasteners to achieve reliable positioning and stable installation of the arc-shaped guide rail 3 on the side plate 4.

[0034] This utility model discloses a massage chair armrest mechanism, which, through the rotatable design of the armrest 1, allows the armrest 1 to switch between a folded state A and a tilted state B. Figure 3 As shown, in the folded state A, the armrest body 11 is attached to the top of the side panel 4 and is in a horizontal or near-horizontal state to save space and facilitate the user's sitting or getting up; in the tilted state B, the front end of the armrest body 11 is raised relative to the folded state A, forming a tilted posture with an angle of 10° to 45° to adapt to the user's arm support needs in a sitting or semi-reclining state.

[0035] This invention overcomes the limitation of traditional fixed armrests that cannot dynamically adapt to changes in sitting posture, ensuring reliable support for the arms at different leaning angles. In particular, when the armrest body 11 integrates massage components, it ensures that the massage area is always in contact with the arm, significantly improving comfort, support, and massage precision, and effectively enhancing the user experience.

[0036] Please see Figures 1-3 As shown, this utility model provides a massage chair, including a chair frame 6, with side support structures on both the left and right sides of the chair frame 6; at least one side support structure is provided with the massage chair armrest mechanism as described above. In this embodiment, both the left and right side support structures of the chair frame 6 are provided with the massage chair armrest mechanism described above, so as to realize the synchronous adjustment and comfortable support of the armrests 1 on both sides.

[0037] In a preferred embodiment, the chair frame 6 includes a backrest frame 61 that can be flipped back and forth. When the backrest frame 61 is flipped back to a reclined position, the armrest 1 can be adjusted to a tilted position B to accommodate the user's leaning posture. Specifically, the tilted position B of the armrest 1 can be linked to the reclined position of the backrest frame 61, so that when the backrest frame 61 is flipped back to the reclined position, the armrest 1 can automatically adjust to the tilted position B to accommodate the user's leaning posture, achieving a coordinated response between the sitting posture and the armrest 1's posture. In other embodiments, the tilt adjustment of the armrest 1 is independent of the flipping action of the backrest frame 61, so that the armrest 1 can be individually adjusted to the tilted position B when the backrest frame 61 is at any angle, to meet the personalized needs of users with different body types or usage habits.
