Technical Field

[0001] The present invention relates to the technical field of office furniture, and in particular to a massage chair. Background Art

[0002] Currently, office workers face health issues such as stiff back muscles and poor circulation due to prolonged sitting. To alleviate these issues, office chairs with integrated massage functions have emerged on the market, with electric massage chairs being the most common. However, existing electric massage chairs have the following major shortcomings: 1) Passive massage: The user's body is completely relaxed during the massage, and muscles are not involved in the exercise, making it impossible to combine physical exercise with massage relaxation; 2) Complex structure and high cost: They require integrated electronic components such as motors, circuit boards, and power supplies, resulting in high manufacturing costs.

[0003] Therefore, how to provide a massage chair with a simple structure, low cost, and the ability to combine active exercise with comfortable massage, especially to provide a smooth and uniform massage experience, is a technical problem that needs to be solved urgently in this field. Summary of the Invention

[0036] Please also refer to Figure 1-Figure 7This embodiment provides a massage chair that converts the user's active movement on the armrest 41 into a massage action on the back through a purely mechanical transmission structure, thereby achieving a combination of exercise and massage. The massage chair includes a chair back 10 and a massage component arranged on the chair back 10, the massage component including: a guide component 20, the guide component 20 being arranged on the chair back 10, the guide component 20 having a first guide section 21 and a second guide section 22; a sliding massage component 30, the sliding massage component 30 being slidably engaged with the guide component 20 to move along the first guide section 21 and the second guide section 22; a drive component 40, the drive component 40 including a movable armrest 41, and a flexible transmission member 42 respectively connected to the armrest 41 and the sliding massage component 30; wherein, when the armrest 41 moves along a preset trajectory, the sliding massage component 30 is driven by the flexible transmission member 42, so that the sliding massage component 30 can rotate along the first guide section 21 and can horizontally translate along the second guide section 22 in response to the movement of the armrest 41.

[0037] In this embodiment, the massage assembly includes a guide assembly 20, a sliding massage assembly 30, and a drive assembly 40. The guide assembly 20 is mounted on the chair back 10. Specifically, the guide assembly 20 can be fixedly mounted on the frame structure of the chair back 10, providing a predetermined trajectory for the movement of the sliding massage assembly 30. The guide assembly 20 has a first guide section 21 and a second guide section 22. These two sections are structurally designed to provide a smooth transition to ensure that the sliding massage assembly 30 can move smoothly from one section to the other. These two sections are used to guide the massage assembly to achieve different types of movement to achieve specific massage effects.

[0038] The sliding massage assembly 30 is slidably engaged with the guide assembly 20. This means that the sliding massage assembly 30 can move along the path defined by the guide assembly 20. Specifically, it can move sequentially or selectively along the first guide section 21 and the second guide section 22. When the sliding massage assembly 30 moves, the massage head 31 carried thereon can massage the user's back.

[0039] The drive assembly 40 is used to convert user manipulation into power to move the sliding massage assembly 30. The drive assembly 40 includes a movable armrest 41 and a flexible transmission member 42 connected to the armrest 41 and the sliding massage assembly 30, respectively. The armrest 41 can be one of the armrests 41 provided on either side of the massage chair, or a joystick specifically designed to drive the massage function. "Moveable" here means that the armrest 41 can be manipulated by the user to produce a certain displacement or rotation, such as movement along a predetermined trajectory. The flexible transmission member 42 can be made of a material with good flexibility and tensile strength, such as a rope, wire rope, or belt. One end of the flexible transmission member 42 is connected to the movable armrest 41, allowing the movement of the armrest 41 to be transmitted to the flexible transmission member 42. The other end of the flexible transmission member 42, or a portion of its transmission path, is connected to the sliding massage assembly 30, thereby transmitting force to the sliding massage assembly 30.

[0040] In the working mode of this embodiment, when the user needs to perform a back massage, the user can hold and move the armrest 41 to move it along a preset trajectory. For example, the user can apply a force to the armrest 41 to cause it to swing horizontally inward (relative to the user's body).

[0041] Since the armrest 41 is connected to the sliding massage assembly 30 via the flexible transmission member 42 , when the armrest 41 moves along a preset trajectory, the sliding massage assembly 30 is driven by the flexible transmission member 42 .

[0042] The key point is that, driven by the flexible transmission member 42 and in response to the movement of the armrest 41, the sliding massage assembly 30's movement pattern changes depending on its position on the guide assembly 20. Specifically, when the sliding massage assembly 30 moves along the first guide section 21, it is capable of rotational motion. This rotational motion allows the massage head 31 to approach and press the user's back in an arcuate trajectory, achieving a gradual, gentle contact and pressing effect, thereby simulating a kneading or acupressure massage. Furthermore, when the sliding massage assembly 30 moves along the second guide section 22, it is capable of horizontal translation. This horizontal translation allows the massage portion to smoothly move across a certain lateral area of ​​the user's back while maintaining a certain pressure depth, providing a smooth and even massage experience and avoiding sudden changes in the pressure sensation caused by changes in the motion trajectory.

[0043] Through the above-described structure, the massage chair of this embodiment, through the user's active operation of the armrest 41, drives the sliding massage assembly 30 via the flexible transmission member 42. Under the guidance of the guide assembly 20, the sliding massage assembly 30 responds to the movement of the armrest 41 by rotating along the first guide section 21 and translating horizontally along the second guide section 22, thereby achieving a combined massage effect. This design combines the user's arm exercise with back massage relaxation, has a simple structure, does not rely on electric drive, and realizes manually controlled active participatory massage.

[0044] In one embodiment, the guide assembly 20 includes a curved portion and a straight portion connected to each other, the curved portion forms the first guide section 21 , and the straight portion forms the second guide section 22 .

[0045] In this embodiment, the curved portion forms the first guide section 21, i.e., the trajectory of the first guide section 21 is arc-shaped. As the sliding massage assembly 30 moves along this first guide section 21 (i.e., the curved portion), it produces a rotational effect around a virtual center point. This design allows the sliding massage assembly 30 to swing forward from an initial position (e.g., away from the user's back) in a gradual and gentle manner, gradually contacting the user's back. The depth of contact increases with the rotation angle, thus achieving a massage effect similar to kneading or pressure points.

[0046] The straight portion forms the second guide section 22, meaning the trajectory of the second guide section 22 is linear. After traversing the first guide section 21 formed by the curved portion, the sliding massage component 30 enters and moves along this second guide section 22 (i.e., the straight portion), performing a horizontal translational motion. This allows the contact depth of the sliding massage component 30 against the user's back to remain relatively constant, providing a uniform massage across a specific lateral area of ​​the back. This avoids the uneven pressure associated with purely circular motion, enhancing the smoothness and comfort of the massage.

[0047] The curved portion and the straight portion are "interconnected", which means that they are structurally continuous or smoothly transitioned, ensuring that the sliding massage component 30 can move smoothly and without jamming when moving from the first guide section 21 (curved portion) to the second guide section 22 (straight portion), or when moving in the opposite direction.

[0048] Therefore, by designing the guide assembly 20 to include a curved portion forming a first guide section 21 and a straight portion forming a second guide section 22, the massage chair of this embodiment can effectively guide the sliding massage assembly 30 to achieve a compound massage movement of first rotating and then translating (or vice versa), thereby providing a diverse and comfortable massage experience.

[0049] To explain in more detail the composite massage motion process guided by the curved and straight parts, a specific scenario is used below:

[0050] Initial State and Startup: The sliding massage assembly 30 is initially located at the starting position of the first guide section 21 (i.e., the curved portion). For example, at this point, its massage head 31 is relatively far from or not yet in contact with the user's back. The user grasps the armrest 41 and begins moving it along a predetermined trajectory, for example, by swinging it inward.

[0051] Phase 1: Rotational motion (along the first guide section 21 / curved portion): When the armrest 41 moves, the sliding massage component 30 is driven by the flexible transmission member 42. The sliding massage component 30 first responds to the movement of the armrest 41 and begins to move along the first guide section 21 of the guide component 20. Since the first guide section 21 is curved, the movement of the sliding massage component 30 appears as a rotational motion. Specifically, its massage head 31 gradually moves forward (towards the user's back) in an arc trajectory, and its contact pressure with the user's back gradually increases. This process achieves a smooth transition from no contact to contact, and simulates a kneading or rotational pressing effect from shallow to deep.

[0052] Transition stage: as the armrest 41 continues to move, the sliding massage component 30 smoothly transitions from the end of the first guide section 21 to the beginning of the second guide section 22 .

[0053] Phase 2: Horizontal Translation (along the Second Guide Section 22 / Straight Portion): After entering the second guide section 22, the sliding massage assembly 30 continues to move in response to the movement of the armrest 41. Because the second guide section 22 is straight, the movement of the sliding massage assembly 30 transitions to horizontal translation. During this phase, the massage heads 31 can smoothly move laterally along the user's back, maintaining the pressure depth achieved at the end of the previous rotational movement. This process allows for horizontal massage of specific areas of the back, providing consistent and even pressure.

[0054] Repeated Massage: When the armrest 41 reaches the end of its preset travel, the sliding massage assembly 30 has correspondingly completed its rotational motion along the first guide section 21 and its horizontal translational motion along the second guide section 22. To achieve a longer massage session, i.e., to enable the sliding massage assembly 30 to repeatedly perform a combined "rotation-translation-translation-rotation" or "translation-translation" massage, the sliding massage assembly 30 must be reset. This reset mechanism is further described in subsequent embodiments.

[0055] Through the above-mentioned compound massage movement of "first rotation and then translation" (or its reverse and reciprocating), and combined with the guide component 20 composed of a curved part and a straight part, the massage chair described in this embodiment can not only achieve a variety of massage movements, from point-shaped and arc-shaped kneading to linear movement, but also ensure the smoothness and comfort of the massage process.

[0056] In one embodiment, the sliding massage assembly 30 includes a sliding seat and a massage head 31 arranged on the sliding seat; the sliding seat includes a sliding bracket 32 ​​and a pulley 33 arranged on the sliding bracket 32, the sliding bracket 32 ​​is connected to the flexible transmission member 42, and the pulley 33 rolls in conjunction with the curved portion and / or the straight portion.

[0057] In this embodiment, the massage head 31 is a component that provides a massage effect. It can be spherical, roller-shaped, acupressure-shaped, or other shapes suitable for massage. The massage head 31 is mounted on the sliding seat and moves along the guide assembly 20 with the sliding seat, thereby providing a massage effect on the user's back.

[0058] The sliding seat is the main structure of the sliding massage assembly 30 , responsible for carrying the massage head 31 and cooperating with the guide assembly 20 to achieve sliding.

[0059] The sliding bracket 32 ​​is the skeleton of the sliding base, provides a mounting position for the massage head 31, and is connected to the flexible transmission member 42 to receive the driving force from the drive assembly 40. For example, the end of the flexible transmission member 42 can be directly fixed to a specific position of the sliding bracket 32.

[0060] The pulley 33 is mounted on the sliding bracket 32. One or more pulleys 33 may be provided. The pulley 33 is configured to engage in rolling engagement with the guide surfaces of the first guide section 21 and / or the second guide section 22 of the guide assembly 20. The rolling motion of the pulley 33 significantly reduces friction between the sliding massage assembly 30 and the guide assembly 20, enabling the sliding massage assembly 30 to move more smoothly and effortlessly along the guide assembly 20 when driven by the flexible transmission member 42, ensuring a smooth massage action and effective drive.

[0061] Specifically, the pulley 33 is capable of rolling engagement with the surface of the curved portion (i.e., the first guide section 21) and / or the straight portion (i.e., the second guide section 22). Whether the sliding massage assembly 30 is rotating on the curved first guide section 21 or translating horizontally on the straight second guide section 22, the pulley 33 effectively contacts and rolls against the guide rail surface, ensuring smooth movement.

[0062] Therefore, by providing a sliding bracket 32 ​​with a pulley 33 as a sliding seat and installing a massage head 31 on this sliding seat, the sliding massage component 30 of this embodiment can move accurately along the guide component 20 in a low-friction manner, thereby achieving a stable and efficient massage function.

[0063] In one embodiment, the sliding bracket 32 ​​includes a traction portion 321 and a bearing portion 322 connected to the traction portion 321; the traction portion 321 is connected to the flexible transmission member 42, and the pulley 33 is arranged on the bearing portion 322, and the bearing portion 322 can rotate relative to the traction portion 321 so that the pulley 33 adaptively fits the straight portion and / or the curved portion.

[0064] In this embodiment, the traction portion 321 is the portion of the sliding bracket 32 ​​primarily responsible for receiving and transmitting driving force. Specifically, the traction portion 321 is connected to the flexible transmission member 42. For example, the distal end of the flexible transmission member 42 may be fixed to the traction portion 321. When the flexible transmission member 42 is pulled, it directly acts on the traction portion 321, thereby driving the entire sliding massage assembly 30.

[0065] The bearing portion 322 is the portion of the sliding bracket 32 ​​primarily responsible for supporting the pulley 33 and massage head 31. As described in the previous embodiment, the pulley 33 is mounted on the bearing portion 322 and engages with the first guide section 21 and / or second guide section 22 of the guide assembly 20 through a rolling engagement. The massage head 31 is also mounted on the bearing portion 322.

[0066] The key point is that the bearing portion 322 is able to rotate relative to the traction portion 321. This rotational connection can be achieved, for example, via a pin, ball joint, or other type of revolving pair. This relative rotational design allows the pulley 33 (disposed on the bearing portion 322) to adaptively conform to the guide surface of the guide assembly 20, particularly when the guide assembly 20 includes straight and / or curved sections.

[0067] Specifically, when the sliding massage assembly 30 transitions from a straight portion to a curved portion of the guide assembly 20, or moves on a curved portion with a varying curvature, the bearing portion 322 rotates relative to the traction portion 321, allowing the pulley 33 to maintain good contact with the guide surface. This prevents the pulley 33 from getting stuck or receiving uneven force due to a rigid connection. This ensures smooth movement and precise guidance of the sliding massage assembly 30 throughout its entire motion.

[0068] Therefore, by designing the sliding bracket 32 ​​to include a traction part 321 and a bearing part 322 that can rotate relative to each other, the massage chair of this embodiment can ensure that the pulley 33 can better adapt to the straight part and / or curved part of the guide component 20, thereby improving the smoothness and reliability of the movement of the sliding massage component 30.

[0069] In one embodiment, a through limiting groove 23 is provided between the curved portion and the straight portion; a limiting plate 323 is provided on the traction portion 321 , and both the limiting plate 323 and the bearing portion 322 are inserted into the limiting groove 23 .

[0070] In this embodiment, the guide assembly 20 is provided with a through-going retaining groove 23 between its curved portion and the straight portion (or, more accurately, through both portions). The "between" here should be understood to mean that the retaining groove 23 extends along the length of the guide assembly 20 and passes through a surface of both the curved portion and the straight portion. This retaining groove 23 provides additional guidance and restraint for a portion of the structure of the sliding bracket 32.

[0071] Correspondingly, a limiting plate 323 is provided on the traction portion 321 of the sliding bracket 32. The limiting plate 323 may be a plate-shaped structure extending from the traction portion 321.

[0072] In the assembled state, the limiting plate 323 on the traction portion 321 and the bearing portion 322 (or at least a portion of the bearing portion 322 ) are both inserted into the limiting groove 23 of the guide assembly 20 .

[0073] This structural design has the following functions:

[0074] The sliding movement of the limiting plate 323 within the limiting groove 23 and the engagement of the portion of the bearing portion 322 within the limiting groove 23 provide additional guidance and positioning for the movement of the sliding massage assembly 30, in addition to the pulley 33 and the guide surface. This effectively prevents the sliding massage assembly 30 from twisting, shaking, or deviating from its intended trajectory during movement.

[0075] The traction portion 321 cooperates with the limiting slot 23 via the limiting plate 323, primarily bearing and transmitting the pulling force from the flexible transmission member 42 and ensuring accurate movement along the length of the guide assembly 20. Simultaneously, the bearing portion 322 is also inserted into the limiting slot 23, which helps the entire structure remain within the correct guide path when the bearing portion 322 rotates relative to the traction portion 321 to adapt to changes in the guide rail's curvature.

[0076] When the flexible transmission member 42 pulls the sliding bracket 32, the limiting plate 323 on the pulling portion 321 slides within the limiting groove 23, while the pulley 33 on the bearing portion 322 rolls along the outer guide surface of the guide assembly 20. This combined internal and external guidance and limiting method makes the movement of the sliding massage assembly 30 more stable and reliable.

[0077] Therefore, by providing a through limiting groove 23 between the curved portion and the straight portion of the guide assembly 20, and providing a limiting plate 323 on the traction portion 321, while allowing the limiting plate 323 and the bearing portion 322 to be inserted into the limiting groove 23, the massage chair of this embodiment can further improve the stability and reliability of the movement of the sliding massage assembly 30, and prevent it from derailing or causing unnecessary shaking.

[0078] In one embodiment, a channel 24 extending along the length direction of the guide assembly 20 is provided inside, and at least a portion of the traction portion 321 is accommodated in the channel 24 and slides with the channel 24; the limiting groove 23 is connected to the channel 24, and the limiting plate 323 extends from the channel 24 and is accommodated in the limiting groove 23.

[0079] In this embodiment, the guide assembly 20 not only has an external guide surface (for the pulley 33 to roll) and the aforementioned limiting groove 23, but also has a through channel 24 inside. The channel 24 extends along the length of the guide assembly 20, passing through its curved and straight portions.

[0080] The traction portion 321 of the sliding bracket 32 ​​is substantially entirely or substantially entirely accommodated and slidably disposed within the channel 24 of the guide assembly 20. One end of the traction portion 321 is connected to the flexible transmission member 42. This means that a portion of the flexible transmission member 42 also penetrates the channel 24 and connects to the traction portion 321. The other end of the traction portion 321 is rotatably connected to the support portion 322. This rotational connection point can be located near the opening of the channel 24 or at an appropriate location to allow the support portion 322 to effectively rotate externally.

[0081] The channel 24 of the guide assembly 20 is communicated with the aforementioned limiting groove 23. This communication can be: the limiting groove 23 is an opening or extension of the channel 24 outward (for example, toward the back of the user).

[0082] In this design, the limiting plate 323 on the pulling portion 321 can be understood as a part of the pulling portion 321 itself, or a structure attached to the pulling portion 321 and extending from the channel 24 into the limiting groove 23. The bearing portion 322 is also connected to the internal pulling portion 321 through the limiting groove 23, and a portion of the structure moves within the limiting groove 23.

[0083] When the flexible transmission member 42 drives the sliding massage assembly 30:

[0084] The traction portion 321 is pulled within the channel 24 of the guide assembly 20, with its movement guided and constrained by the channel 24, ensuring accurate movement. The limiting plate 323 on the traction portion 321 slides within the limiting groove 23 connected thereto, providing additional lateral restraint to prevent the traction portion 321 from undesirably rotating or shaking within the channel 24.

[0085] Because the bearing portion 322 is rotatably connected to the traction portion 321, and the pulley 33 thereon engages the outer guide surface (curved portion and / or straight portion) of the guide assembly 20, the bearing portion 322 rotates relative to the traction portion 321 according to the shape of the outer guide surface. The portion of the bearing portion 322 within the limiting groove 23 also moves accordingly, but is also constrained by the limiting groove 23.

[0086] The cooperation between the limiting plate 323 and the limiting slot 23 provides additional constraints on the movement of the sliding seat, effectively limiting its motion trajectory and ensuring that the sliding seat always maintains the correct posture during movement. This prevents twisting, shaking, blocking, or derailment caused by uneven force or lateral torque, significantly improving the stability and reliability of movement. The design of the channel 24 connecting to the limiting slot 23 and the majority of the traction portion 321 being located in the channel 24 further enhances this constraint and guidance effect.

[0087] By accommodating the traction portion 321 in the channel 24 of the guide assembly 20 and connecting the channel 24 with the limiting groove 23, the massage chair of this embodiment achieves more comprehensive and stable guidance and limitation of the sliding massage assembly 30, ensuring its stability, accuracy and reliability during complex movements (combination of rotation and translation), while also making the overall structure more compact.

[0088] In a specific embodiment, the traction portion 321 includes a traction body 3211 and a roller 3212 disposed on the traction body 3211 . The tread of the roller 3212 is attached to the inner wall of the channel 24 to achieve sliding fit between the traction portion 321 and the channel 24 .

[0089] In one embodiment, to facilitate smoother adaptive rotation of the bearing portion 322 along the curved portion of the guide assembly 20, the bearing portion 322 and the traction portion 321 initially form a pre-set non-straight angle at their respective primary extension directions at their pivotal connection, i.e., the angle is neither 180 degrees nor 0 degrees. This non-straight angle arrangement helps generate an effective steering torque on the bearing portion 322 when the traction portion 321 is driven by tension, thereby guiding it to smoothly rotate along the curved portion with the assistance of the pulley 33.

[0090] In one embodiment, the massage component includes a plurality of guide components 20 arranged in a vertical direction, and a plurality of sliding massage components 30 arranged corresponding to each guide component 20; the flexible transmission member 42 includes a main transmission member 421 and a plurality of sub-transmission members 422 arranged on the main transmission member 421, and each sub-transmission member 422 is connected to the corresponding sliding massage component 30.

[0091] In this embodiment, multiple independent sets of "guide assembly 20 - sliding massage assembly 30" units are spaced apart along the interior of the chair back 10 from top to bottom. For example, two, three, or even more sets of these units can be provided. This multi-point vertical arrangement allows the massage chair to simultaneously massage different height areas of the user's back, expanding the massage coverage.

[0092] In order to synchronously drive the multiple sliding massage assemblies 30 arranged in the vertical direction through a single operation, this embodiment has correspondingly designed the structure of the flexible transmission member 42. Specifically, the flexible transmission member 42 includes a main transmission member 421 and multiple sub-transmission members 422 arranged on the main transmission member 421.

[0093] The main transmission member 421 is the part responsible for transmitting the main driving force in the flexible transmission member 42. One end of the main transmission member 421 is connected to the movable handrail 41. For example, the main transmission member 421 can be a long rope arranged in the vertical direction.

[0094] The sub-transmission members 422 are multiple shorter transmission cables branching from the main transmission member 421. Specifically, the main transmission member 421 is provided with multiple branch points at different locations along its length, each connected to a sub-transmission member 422. Each sub-transmission member 422 is connected to a corresponding sliding massage assembly 30, specifically to the traction portion 321 of the sliding massage assembly 30.

[0095] When a user moves the armrest 41, the movement of the armrest 41 directly pulls the main transmission member 421. Because multiple sub-transmission members 422 are connected to the main transmission member 421, the movement of the main transmission member 421 simultaneously drives all of the sub-transmission members 422 connected to it. Furthermore, each sub-transmission member 422 drives the connected sliding massage assembly 30 to move along its corresponding guide assembly 20.

[0096] This "main transmission member 421 - multiple sub-transmission members 422" structure allows a single operation of the armrest 41 to synchronously drive multiple vertically arranged sliding massage assemblies 30 to perform a massage action. This not only improves the efficiency and coverage of the massage, but also maintains the simplicity of manual actuation.

[0097] Therefore, by setting up multiple guide components 20 and corresponding multiple sliding massage components 30 arranged in the vertical direction, and adopting a flexible transmission component 42 composed of a main transmission component 421 and multiple sub-transmission components 422, the massage chair of this embodiment can achieve synchronous massage of multiple areas of the user's back, thereby improving the massage effect and user experience.

[0098] In one embodiment, the armrest 41 includes a supporting portion 412 and a driving arm 413 that are connected to each other. The supporting portion 412 and the driving arm 413 are connected to the chair back 10 via a pivot, and the main transmission member 421 is connected to one end of the driving arm 413 away from the pivot.

[0099] In this embodiment, the support portion 412 is a portion of the armrest 41 designed for the user to place his or her arms. The user activates and controls the massage function by applying a force to the support portion 412 (e.g., swinging it inward or outward).

[0100] The driving arm 413 is the part of the armrest 41 that is primarily responsible for transmitting the motion of the supporting portion 412 to the flexible transmission member 42 (specifically, the main transmission member 421). The driving arm 413 may be an arm-shaped structure extending downward, backward, or at other suitable angles from the supporting portion 412.

[0101] The support portion 412 and the drive arm 413 (or, in other words, an intermediate position of the armrest 41) are connected to the chair back 10 via a pivot. The armrest 41 can rotate relative to the chair back 10 (e.g., swing in a horizontal plane) about this pivot. This pivot point serves as the fulcrum for the movement of the armrest 41.

[0102] The main transmission member 421 is connected to an end of the driving arm 413 away from the pivot.

[0103] When the user applies a force to the support portion 412 to pivot it, the end of the drive arm 413 moves in the opposite direction due to the lever effect. Because the main transmission member 421 is connected to the end of the drive arm 413 away from the pivot, the movement of this end effectively pulls or releases the main transmission member 421, thereby driving the entire massage assembly.

[0104] Through the pivotal connection between the armrest 41 and the chair back 10 and the fixed connection between the armrest 41 and the main transmission member 421, the user can apply a small swinging force to the armrest 41 and use the lever principle to convert this action into an effective pull on the main transmission member 421.

[0105] Therefore, by designing the armrest 41 to include a supporting portion 412 and a driving arm 413, and connecting the armrest 41 (specifically between the supporting portion 412 and the driving arm 413) to the chair back 10 through a pivot, and connecting the main transmission member 421 to the end of the driving arm 413 away from the pivot, the massage chair of this embodiment enables the user to drive the massage component with a smooth movement, thereby improving the operating comfort and driving efficiency.

[0106] In one embodiment, the pivotal connection between the armrest 41 and the chair back 10 can be achieved by a pivotal connection member, such as a pivoting angle iron 45. One side of the pivoting angle iron 45 can be fixed to the chair back 10. The other side of the pivoting angle iron 45 is pivotally connected to the middle portion of the armrest 41 via a pin or other pivoting joint. In this way, the armrest 41 can swing smoothly about the pivot point formed by the pivoting angle iron 45.

[0107] In one embodiment, a vertical through-hole 43 may be formed in the rotating angle iron 45. The vertical portion of the main transmission member 421 is passed through the through-hole 43. The through-hole 43 provides a preliminary constraint and guidance for the vertical position of the main transmission member 421, preventing it from excessive lateral displacement during transmission.

[0108] A guide structure 44 is provided in front of the driving arm 413 of the handrail 41, that is, in the direction closer to the user. The guide structure 44 has a slot with a smooth inner wall. Its core function is to change the direction of movement of the main transmission member 421. After the vertical portion of the main transmission member 421 passes through the through hole 43 on the rotating angle iron 45, it continues to extend downward and enters the guide structure 44, and smoothly turns from a vertical direction to an approximately horizontal direction in the slot of the guide structure 44. Finally, the approximately horizontal portion of the main transmission member 421 drawn out from the guide structure 44 is fixedly connected to the end of the driving arm 413 away from the rotating angle iron 45.

[0109] When a user swings the support portion 412 of the armrest 41, the armrest 41 rotates about the rotating angle iron 45. The end of the driving arm 413 swings accordingly. Since the horizontal portion of the main transmission member 421 is fixed to the end of the driving arm 413, the swinging of the driving arm 413 directly pulls the horizontal portion of the main transmission member 421.

[0110] The pulling force or displacement is transmitted to the vertical portion of the main transmission member 421 through the guide structure 44. The vertical portion of the main transmission member 421 moves up and down under the guidance of the through hole 43 of the rotating angle iron 45, thereby driving the multiple sub-transmission members 422 and the sliding massage assembly 30 connected thereto.

[0111] This dual-guiding and limiting design ensures that the flexible transmission member 42 can always move along a predetermined path, effectively avoiding problems such as loosening, shaking, entanglement, or interference with other components during the transmission process, and ensuring direct, stable, and efficient force transmission.

[0112] Through the above-mentioned specific pivot structure and the multi-point limiting and guiding structure 44 of the main transmission member 421, the massage chair of this embodiment not only realizes labor-saving and efficient lever driving, but also ensures the stability and reliability of the transmission process, thereby improving the user experience and product durability.

[0113] In one embodiment, the massage assembly further includes a synchronization rod 50 , and the synchronization rod 50 is respectively connected to the plurality of sliding massage assemblies 30 arranged in a vertical direction.

[0114] In this embodiment, the massage assembly includes a plurality of guide assemblies 20 arranged vertically and a plurality of sliding massage assemblies 30 corresponding to each guide assembly 20. Although these sliding massage assemblies 30 are synchronously driven by a main transmission member 421 and a sub-transmission member 422, in actual operation, slight differences in the length of each sub-transmission member 422, the forces acting at the connection points, and the friction between each sliding massage assembly 30 and the corresponding guide assembly 20 may result in incomplete synchronization of the movement of the sliding massage assemblies 30, such as slightly different start times or slightly different movement speeds.

[0115] To solve this problem, the synchronization rod 50 is introduced. The synchronization rod 50 is a rigid rod, such as a metal rod or a hard plastic rod. It is configured to penetrate or connect all the sliding massage assemblies 30 arranged in the vertical direction.

[0116] There are many specific connection methods:

[0117] The synchronization rod 50 may pass through a guide groove provided on each sliding massage assembly 30 (e.g., on its sliding bracket 32 ​​or massage head 31). Alternatively, the synchronization rod 50 may be fixedly connected to each sliding massage assembly 30 (e.g., on its sliding bracket 32 ​​or massage head 31) via a connecting member.

[0118] When one of the sliding massage assemblies 30 starts to move due to the drive of the flexible transmission member 42, the movement is transmitted to all other sliding massage assemblies 30 connected to the synchronization rod 50 through the synchronization rod 50, forcing them to move with the same displacement and approximately the same speed.

[0119] This effectively solves the problem of inconsistent and asynchronous movement of the various sliding massage components 30 due to slight differences in the force, length, or connection points of the flexible transmission member 42 (especially the multiple sub-transmission members 422). By introducing the synchronization rod 50, it is ensured that the multiple sliding massage components 30 arranged in the vertical direction can complete rotational movement and horizontal translational movement in a more coordinated and consistent manner under the drive of the armrest 41, thereby providing a more regular and synchronized massage experience and improving the integrity and stability of the massage action. For example, even if a sub-transmission member 422 is slightly loose, or the initial friction of a sliding massage component 30 is slightly greater, the synchronization rod 50 can "drive" or "constrain" it through other sliding massage components 30 that have already started to move, ensuring the synchronization of the overall movement.

[0120] Therefore, by adding a synchronization rod 50 in the massage assembly that is respectively connected to the multiple sliding massage assemblies 30 arranged in the vertical direction, the massage chair of this embodiment can further improve the synchronization and coordination of the movements between the multiple sliding massage assemblies 30, thereby providing a more regular and consistent massage experience.

[0121] In one embodiment, the massage components are provided in two rows, and the two rows of massage components are symmetrically arranged on the chair back 10; in the two rows of massage components, a reset component 60 is provided between the two adjacent sliding massage components 30 on the left and right, and the reset component 60 is used to drive the sliding massage component 30 to return to the initial position.

[0122] In this embodiment, a set of massage components is provided on the left and right sides in front of the chair back 10. Each set of massage components includes a plurality of guide components 20 and a corresponding plurality of sliding massage components 30 arranged in a vertical direction, as well as a drive component 40 (including armrests 41 and flexible transmission members 42) that drives them to move. The two rows of massage components are mirror-symmetrical in structure and function. This bilaterally symmetrical layout enables the massage chair to massage the left and right sides of the user's back at the same time, providing a more comprehensive and balanced massage experience with a wider coverage. Among them, the left armrest 41 drives a set of massage components on the left, and the right armrest 41 drives a set of massage components on the right.

[0123] In order to realize automatic resetting of the massage function, that is, when the user stops applying external force (for example, releasing the armrest 41), the sliding massage component 30 can automatically return to the initial, non-working position, this embodiment introduces a resetting component 60.

[0124] Specifically, within the two rows of massage assemblies, the reset assembly 60 is disposed between two adjacent sliding massage assemblies 30. "Adjacent" here refers to two sliding massage assemblies 30 located in the left and right massage assembly groups, respectively, and positioned at approximately the same vertical height or corresponding positions. If each massage assembly group includes multiple sliding massage assemblies 30 arranged vertically, a reset assembly 60 may be disposed between each pair of corresponding sliding massage assemblies 30.

[0125] The reset assembly 60 is used to drive the sliding massage assembly 30 to return to the initial position. The reset assembly 60 is an elastic element, such as a tension spring.

[0126] Working method description:

[0127] Initial State: When the massage function is not in use, the left and right sliding massage assemblies 30 are in their initial positions, for example, at the beginning of the first guide section 21 of the guide assembly 20, with the massage heads 31 facing away from the user's back. At this point, the reset assembly 60 is in a slightly pre-stretched state.

[0128] Massage Process: When the user operates the armrest 41, the flexible transmission member 42 drives the sliding massage assembly 30 on the corresponding side to move along the guide assembly 20. During massage, the sliding massage assemblies 30 of the two rows of massage assemblies move away from each other, with the left row moving toward the left and the right row moving toward the right. The reset assembly 60 connected between them is stretched, thereby storing elastic potential energy.

[0129] Reset process: When the user stops applying driving force to the armrest 41, the elastic potential energy previously stored in the reset component 60 will be released. The restoring force generated by the reset component 60 will act on the sliding massage components 30 on the left and right sides to which it is connected, driving them to move towards each other, that is, returning to their initial positions. As the sliding massage component 30 is reset to its initial position, the tension on the flexible transmission member 42 connecting the armrest 41 and the sliding massage component 30 will decrease or disappear (that is, the flexible transmission member 42 becomes relaxed). At this time, since the external force driving the armrest 41 has been removed and the flexible transmission member 42 no longer applies continuous tension to it, the armrest 41 is no longer forced to remain in the massage working position. The user can easily move the armrest 41 back to its initial position manually.

[0130] By providing two rows of symmetrical massage components and a reset component 60 therebetween, this embodiment not only enhances the coverage and symmetry of the massage, but also increases the usability and convenience of the massage chair, so that the user does not need to manually return the massage components to their original positions when the massage is finished.

[0131] Therefore, by providing two rows of symmetrical massage components and providing a reset component 60 between the left and right adjacent sliding massage components 30, the massage chair of this embodiment can not only provide symmetrical and comprehensive massage, but also realize automatic reset of the massage function, thereby improving the convenience of use.

[0132] In one embodiment, the left end of the reset assembly 60 is fixedly connected to the bearing portion 322 of the left massage assembly, and the right end is fixedly connected to the bearing portion 322 of the right massage assembly.

[0133] In a specific embodiment, a torsion spring may be provided at the pivot connection between the armrest 41 and the chair back 10 , and the torsion spring tends to return the armrest 41 to its initial position when there is no external driving force.

[0134] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
