Description

Technical Field

[0001] This utility model relates to the field of office furniture technology, and in particular to a massage structure and device. Background Technology

[0002] Currently, office workers commonly face health problems such as stiff back muscles and poor blood circulation due to prolonged sitting. To alleviate these issues, various massage devices have emerged on the market, including office chairs with integrated massage functions. These massage chairs typically include massage components that move along predetermined guide rails to massage areas such as the user's back.

[0003] However, in some existing massage structures, the guide rail design mainly or only adopts a curved shape. In practical applications, especially when the sliding massage component moves along this single curved guide rail, it will cause uneven massage pressure, which will greatly reduce the experience of the entire massage process. It is not only difficult to provide a smooth and comfortable massage feeling, but also affects the actual therapeutic effect of the massage.

[0004] Therefore, how to provide a massage structure that can deliver a smooth, even, and comfortable massage experience is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The main purpose of this utility model is to provide a massage structure and device to solve the above-mentioned technical problems.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A massage structure, comprising:

[0008] A guide assembly having interlocking curved guide portions and straight guide portions; and

[0009] A sliding massage component, which is slidably coupled to the guide component, and which, in response to the drive of the drive component, is capable of moving in an arc along the curved guide portion and in a straight line along the straight guide portion;

[0010] The sliding massage component includes:

[0011] A traction unit, the traction unit being connected to the drive assembly to receive and transmit driving force; and

[0012] A support portion, rotatably connected to the traction portion, wherein the support portion is provided with rolling elements for rolling engagement with the curved guide portion and the straight guide portion; and

[0013] A massage head is disposed on the support portion;

[0014] The rotation of the bearing portion relative to the traction portion allows the rolling element to conform to the curved guide portion and the straight guide portion when the sliding massage assembly transitions from the curved guide portion to the straight guide portion.

[0015] The guide component has a limiting groove on its surface that extends along its length and passes through the curved guide portion and the straight guide portion, and the bearing portion passes through and is slidably disposed in the limiting groove.

[0016] The guide assembly has a channel extending along its length and passing through the curved guide portion and the straight guide portion. The traction portion is disposed in the channel and slides with the channel. The limiting groove is connected to the channel, and the traction portion has a limiting plate extending into the limiting groove.

[0017] The traction unit includes a traction body and a traction rolling element disposed on the traction body; the traction body is connected to the drive assembly and the bearing part respectively, and the traction rolling element rolls in cooperation with the inner wall of the channel.

[0018] The drive assembly includes an operating part and a flexible transmission component connected to the operating part and the traction part respectively.

[0019] The system includes multiple guide components arranged along a preset direction, and multiple sliding massage components that correspond one-to-one with each of the guide components; the flexible transmission component includes a main transmission component connected to the operation unit and multiple sub-transmission components disposed on the main transmission component, and the multiple sub-transmission components are respectively connected to the traction part of the corresponding sliding massage component.

[0020] It also includes a synchronizing rod, which is connected to the support portion or the massage head of a plurality of sliding massage components arranged along the preset direction.

[0021] A massage device includes: two rows of massage structures, the two rows of massage structures being arranged symmetrically on the left and right, and each row of massage structures being the massage structure described above.

[0022] Among them, a reset component is provided between two adjacent sliding massage components in the two columns of massage structure. The reset component is used to drive the two sliding massage components back to their initial positions.

[0023] The beneficial technical effects of this utility model are as follows:

[0024] This invention employs a composite guide rail composed of interconnected curved and straight guide sections, and designs the sliding massage component with a rotatable connection between the traction section and the support section. This rotatable connection structure gives the support section the ability to adaptively adjust its posture, ensuring that the rolling elements on it smoothly conform to the guide rail surface as the massage component transitions along the guide rail from the curved guide section to the straight guide section (or vice versa). More importantly, when the rolling elements move on the straight guide section, it ensures a constant relative distance between the massage head on the support section and the guide rail, ultimately translating into uniform and comfortable massage pressure. This effectively solves the pain points of uneven massage pressure and poor experience caused by a single curved guide rail in the prior art, ultimately providing users with a high-quality massage experience that combines diverse modes with smoothness, comfort, and balanced pressure.

[0039] Please also refer to Figures 1-4This embodiment provides a massage structure designed to achieve a smooth, comfortable, and multi-mode massage experience through a combination of guiding and sliding. The massage structure includes a guide component 20 having interconnected curved guide portions 21 and straight guide portions 22; and a sliding massage component 30 slidably fitted to the guide component 20. The sliding massage component 30, responsive to the drive component 40, can move in an arc along the curved guide portion 21 and in a straight line along the straight guide portion 22. The sliding massage component 30 includes a traction portion 321 for connecting with the drive component 40. The device includes a receiving and transmitting drive force; and a support portion 322 rotatably connected to the traction portion 321, the support portion 322 having rolling elements for rolling engagement with the curved guide portion 21 and the linear guide portion 22; wherein, the rotation of the support portion 322 relative to the traction portion 321 causes the rolling elements to conform to the curved guide portion 21 and the linear guide portion 22 when the sliding massage assembly 30 transitions from the curved guide portion 21 to the linear guide portion 22.

[0040] In this embodiment, the massage structure includes a guide component 20 and a sliding massage component 30.

[0041] The guide component 20 guides the movement path of the sliding massage component 30. The guide component 20 has a curved guide portion 21 and a straight guide portion 22 that are connected to each other. One surface of the curved guide portion 21 has a certain curvature to guide the sliding massage component 30 in an arc-shaped movement, thereby simulating massage techniques such as kneading or rotating pressing. The straight guide portion 22 is straight, with one surface being flat, to guide the sliding massage component 30 in a straight line, thereby achieving, for example, a smooth pushing massage. The curved guide portion 21 and the straight guide portion 22 are smoothly connected to each other to ensure that the sliding massage component 30 transitions smoothly without jamming between them. In one application scenario, such as... Figure 1 As shown, the guide component 20 can be installed on the backrest 10 of the massage chair to provide massage for the user's back and other areas.

[0042] The sliding massage component 30 is slidably coupled to the guide component 20. Responding to the actuation of the external drive component 40, the sliding massage component 30 can slide on the guide component 20. The specific structure of the drive component 40 will be detailed in subsequent embodiments; here, only its driving function is referred to. Specifically, when the sliding massage component 30 moves along the curved guide portion 21, it performs an arc-shaped movement; when it moves along the straight guide portion 22, it performs a linear movement. This composite motion trajectory provides a diverse massage experience.

[0043] Reference Figure 5 and Figure 6 The sliding massage component 30 includes a traction part 321 and a support part 322.

[0044] The traction unit 321 is connected to the drive assembly 40 to receive and transmit driving force from the drive assembly 40. This driving force enables the entire sliding massage assembly 30 to move along the guide assembly 20.

[0045] The support portion 322 is rotatably connected to the traction portion 321. This rotatable connection can be achieved, for example, by a pin or other revolute joint structure known in the art, allowing the support portion 322 to rotate at a certain angle relative to the traction portion 321. The support portion 322 is provided with a rolling element for rolling engagement with the curved guide portion 21 and the linear guide portion 22. In this embodiment, the rolling element can specifically be a pulley 33, which is mounted on the support portion 322 and can make rolling contact with the guide surfaces of the guide assembly 20 (i.e., the surfaces of the curved guide portion 21 and the linear guide portion 22), thereby reducing sliding friction and making the movement of the sliding massage assembly 30 smoother. The support portion 322 is provided with a massage head 31, which is a component that directly contacts the user's body and applies a massage effect. Specifically, the massage head 31 is fixedly mounted at the end of the support portion 322 away from the traction portion 321, so that when the sliding massage assembly 30 moves along the guide assembly 20, the massage head 31 can move accordingly. By setting the massage head 31, the sliding massage component 30 can achieve effects such as pressing and kneading when it moves in an arc along the curved guide portion 21; and can achieve effects such as massage and scraping when it moves in a straight line along the straight guide portion 22.

[0046] The rotational design of the bearing portion 322 relative to the traction portion 321 allows the rolling element to adaptively adjust its posture when the sliding massage assembly 30 transitions from the curved guide portion 21 to the straight guide portion 22, or vice versa, or when moving on the curved guide portion 21 with changing curvature. This ensures that the rolling element always conforms to both the curved guide portion 21 and the straight guide portion 22. For example, when the sliding massage assembly 30 enters the curved guide portion 21 from the straight guide portion 22, the bearing portion 322 rotates relative to the traction portion 321 due to the change in the curvature of the guide rail. This allows the rolling element on it to maintain good rolling contact with the guide rail surface, avoiding jamming that may occur due to rigid connections. This ensures the stability and guiding accuracy of the sliding massage assembly 30 throughout the entire movement process, thereby improving the comfort and uniformity of the massage.

[0047] Through the above structure, the massage structure of this embodiment, with its guide component 20 having interconnected curved guide portion 21 and straight guide portion 22, and its sliding massage component 30 including a rotatably connected traction portion 321 and support portion 322, and the support portion 322 being provided with a rolling element that rolls in cooperation with the guide portion, achieves the following effects: First, the rotatability of the support portion 322 relative to the traction portion 321 ensures that the rolling element can always fit well against the surface of the guide component 20 when the sliding massage component 30 transitions from the curved guide portion 21 to the straight guide portion 22 (or vice versa), and when moving along the curved guide portion 21 with varying curvature. This improves the overall stability and smoothness of the movement of the sliding massage component 30, effectively avoiding jamming or discontinuous movement caused by changes in the curvature of the guide rail. Secondly, when the sliding massage component 30 moves linearly along the linear guide portion 22, the rolling element can continuously and stably conform to the linear guide portion, ensuring that the relative distance (i.e., massage depth) between the massage head 31 on the support portion 322 and the massaged surface remains essentially constant during this linear movement. This stability of massage depth directly results in balanced massage pressure, preventing fluctuations in massage intensity during linear massage, thus providing a smoother and more comfortable massage experience. Therefore, the massage structure of this embodiment, through the above design, not only achieves a composite massage motion combining arcs and straight lines, but more importantly, improves the smoothness and comfort of the massage process, especially ensuring pressure balance during the linear massage phase.

[0048] In one embodiment, the guide component 20 has a limiting groove 23 extending along its length and penetrating the curved guide portion 21 and the straight guide portion 22 on its surface, and the bearing portion 322 is inserted through and slidably disposed within the limiting groove 23.

[0049] In this embodiment, to further improve the stability and guiding accuracy of the sliding massage component 30 when it moves along the guide component 20, a limiting groove 23 is provided on the surface of the guide component 20, extending along its length and penetrating the curved guide portion 21 and the straight guide portion 22. The limiting groove 23 forms a preset trajectory, constraining part of the structure of the sliding massage component 30.

[0050] Accordingly, the support portion 322 of the sliding massage component 30 is inserted through and slidably disposed within the limiting groove 23. This means that at least a portion of the support portion 322 extends into the limiting groove 23 and can slide freely along the extending direction of the limiting groove 23. Through the cooperation between the limiting groove 23 and the support portion 322, the sliding massage component 30 can be effectively prevented from lateral swaying, shaking, or deviating from the predetermined path of the guide component 20 during movement. This structural design, combined with the rolling cooperation between the rolling elements on the support portion 322 and the surface of the guide component 20, jointly ensures the smoothness and reliability of the movement of the sliding massage component 30.

[0051] In one embodiment, the guide assembly 20 is provided with a channel 24 extending along its length and penetrating the curved guide portion 21 and the straight guide portion 22, the traction portion 321 is disposed in the channel 24 and slides in cooperation with the channel 24; the limiting groove 23 is connected to the channel 24, and the traction portion 321 is provided with a limiting plate 323 extending into the limiting groove 23.

[0052] In this embodiment, to make the guidance of the traction part 321 more reliable, the guide assembly 20 has a channel 24 extending along its length and penetrating the curved guide part 21 and the straight guide part 22 inside. The traction part 321 is disposed within the channel 24 and slides with the channel 24. This means that the main body of the traction part 321 is accommodated in the channel 24 formed inside the guide assembly 20, and the inner wall of the channel 24 provides guidance for the linear movement of the traction part 321.

[0053] Furthermore, the limiting groove 23 is connected to the channel 24. This connection structure creates an opening between the internal space (channel 24) of the guide assembly 20 and the external limiting groove 23. The traction part 321 is provided with a limiting plate 323 extending into the limiting groove 23. The limiting plate 323 can be understood as a part of the structure extending from the main body of the traction part 321, which passes through the connection between the channel 24 and the limiting groove 23 and enters the limiting groove 23.

[0054] In this structure, the traction unit 321 mainly slides within the channel 24, and its movement is guided by the inner wall of the channel 24. The limiting plate 323, which is provided on the traction unit 321, slides within the limiting groove 23, which can assist in guiding the movement of the traction unit 321, further improving the overall stability of the movement. At the same time, the traction unit 321 being housed within the channel 24 makes the entire structure more compact.

[0055] In one embodiment, the traction unit 321 includes a traction body 3211 and a traction rolling element disposed on the traction body 3211; the traction body 3211 is connected to the drive assembly 40 and the support part 322 respectively, and the traction rolling element rolls in cooperation with the inner wall of the channel 24.

[0056] In this embodiment, the traction body 3211 is the main load-bearing structure of the traction part 321. One end of it is used to connect with the drive component 40 to receive the driving force; the other end of it is rotatably connected to the support part 322 to transmit the driving force to the support part 322 and drive the entire sliding massage component 30 to move.

[0057] The traction rolling element 3212, for example, can be a small roller, which is mounted on the traction body 3211 and rolls against the inner wall of the channel 24. By converting the sliding friction between the traction part 321 and the inner wall of the channel 24 into rolling friction, the resistance of the traction part 321 when moving within the channel 24 can be reduced, making the drive more effortless and the movement smoother. This also reduces wear on components and extends their service life. For example, multiple traction rolling elements 3212 can be provided on the side of the traction body 3211, allowing them to contact and roll against the corresponding inner wall surfaces of the channel 24.

[0058] With this design, the traction unit 321 can not only effectively transmit driving force, but also achieve low-friction, high-efficiency guiding motion within the channel 24.

[0059] In one embodiment, the drive assembly 40 includes an operating part and a transmission member connected to the operating part and the traction part 321, respectively.

[0060] In this embodiment, the operating part is a component used by the user to apply driving force. In a specific application scenario, such as a massage chair, the operating part may specifically be a movable component disposed on the chair body (e.g., the backrest 10 or armrests). In this embodiment, referring to... Figure 7 The operating part may specifically be an armrest 41. The user can generate driving force by rotating or otherwise operating the armrest 41.

[0061] The transmission component is used to transmit the force or displacement applied by the user on the operating part (e.g., armrest 41) to the traction part 321 of the sliding massage assembly 30, thereby driving the sliding massage assembly 30 to move along the guide assembly 20. In this embodiment, the transmission component can specifically be a flexible transmission component 42, such as a pull rope. One end of the flexible transmission component 42 is connected to the operating part, and the other end is connected to the traction part 321 of the sliding massage assembly 30. When the user operates the armrest 41, the movement of the armrest 41 is transmitted to the traction part 321 through the flexible transmission component 42, thereby pulling the sliding massage assembly 30 to move.

[0062] For example, such as Figure 7 As shown, the armrest 41 can be connected to the flexible transmission component 42 via its drive arm 413. When the user swings the armrest 41 inward or outward, the drive arm 413 pulls or releases the flexible transmission component 42, thereby driving the sliding massage component 30. This design allows the user to control the start, stop, and rhythm of the massage through natural arm movements, achieving manual drive, a simple structure, and requiring no additional power source.

[0063] In one embodiment, the system includes a plurality of guide components 20 arranged along a preset direction, and a plurality of sliding massage components 30 corresponding to each of the guide components 20. The transmission component includes a main transmission component 421 connected to the operation unit and a plurality of sub-transmission components 422 disposed on the main transmission component 421. The plurality of sub-transmission components 422 are respectively connected to the traction part 321 of the corresponding sliding massage component 30.

[0064] In this embodiment, to achieve simultaneous massage of a large area such as the user's back, the massage structure includes multiple guide components 20 arranged along a preset direction, and multiple sliding massage components 30 corresponding to each guide component 20. The preset direction is a vertical direction, i.e., arranged along the height of the chair back 10. Figure 1 As shown, this allows for simultaneous massage of different height areas of the back.

[0065] Accordingly, in order to simultaneously drive these multiple sliding massage components 30 arranged in a preset direction through a single operating unit, the structure of the transmission member is also specifically designed. The transmission member includes a main transmission member 421 connected to the operating unit and multiple sub-transmission members 422 disposed on the main transmission member 421.

[0066] The main drive component 421 is the main transmission part that directly receives the driving force from the operating unit. For example, the main drive component 421 can be a long pull rope, one end of which is connected to the drive arm 413 of the handrail 41.

[0067] The plurality of sub-drive members 422 branch off from the main drive member 421 or are otherwise connected to different positions on the main drive member 421. Each sub-drive member 422 is connected to the traction portion 321 of the corresponding sliding massage assembly 30. For example, as Figure 7 As shown, the main drive component 421 is arranged vertically, and multiple shorter sub-drive components 422 branch off at different points along its length. Each sub-drive component 422 is connected to the traction part 321 of a sliding massage assembly 30 at a corresponding height.

[0068] Through this "one-to-many" transmission structure, when a user operates one control unit, the main transmission component 421 is driven, which in turn drives all the connected sliding massage components 30 to move along their respective guide components 20 via multiple sub-transmission components 422. In this way, simultaneous massage of multiple areas of the back can be achieved with just one operation, improving massage efficiency and coverage while also simplifying operation.

[0069] In one embodiment, a synchronization rod 50 is also included, which is connected to the support portion 322 or the massage head 31 of a plurality of sliding massage components 30 arranged along the preset direction.

[0070] In this embodiment, to further ensure that the multiple sliding massage components 30 arranged along the preset direction, such as the vertical direction, can move more in a coordinated manner when driven by the main drive member 421 and the sub-drive member 422, and to avoid asynchronous movement caused by slight length differences, uneven force distribution, or friction differences between each sliding massage component 30 and the corresponding guide component 20, the massage structure of this embodiment also includes a synchronization rod 50.

[0071] The synchronizing rod 50 is a rigid rod extending along the preset direction and connected to corresponding parts of the plurality of sliding massage components 30 arranged in that direction, for example, to the support portion 322 or massage head 31 of each sliding massage component 30. Through the connection of the synchronizing rod 50, when one sliding massage component 30 begins to move, it drives the other connected sliding massage components 30 to move simultaneously with the same displacement and speed. Even if a sub-drive component 422 is slightly loose, or the initial friction of a sliding massage component 30 is slightly high, the synchronizing rod 50 can still "help" or "constrain" that component by transmitting force, thereby ensuring that all sliding massage components 30 connected by the synchronizing rod 50 move synchronously as a whole, providing a more regular and uniform massage experience.

[0072] like Figures 5-7As shown, corresponding to the massage structure in the aforementioned embodiment, this utility model embodiment also provides a massage device, which includes two rows of massage structures, the two rows of massage structures being arranged symmetrically on the left and right, and each row of massage structures being the massage structure described in the aforementioned embodiment.

[0073] In this embodiment, the massage device can be used as a massage component of a massage chair, which includes a backrest 10 serving as a base. Two rows of massage structures are symmetrically arranged on the backrest 10. This symmetrical layout allows the device to simultaneously provide a balanced and symmetrical massage to both sides of the user's back during operation, offering a more comprehensive and comfortable massage experience and avoiding the postural imbalance that may result from unilateral massage.

[0074] Each row of massage structures can employ any of the massage structures described in the foregoing embodiments. Specifically, each row of massage structures includes a guide component 20 and a sliding massage component 30. In a specific example, such as Figure 1 As shown, three sets of massage structures arranged vertically are provided on each of the left and right sides of the chair back 10 to cover different areas of the user's back. Each row of massage structures is driven by its drive component 40, such as the armrest 41 located on the side of the chair back 10. The user can drive the left row of massage structures by operating the left armrest 41 and the right row of massage structures by operating the right armrest 41, thus achieving a combination of zone control and active massage.

[0075] In one embodiment, a reset component 60 is provided between two adjacent sliding massage components 30 in the two-column massage structure. The reset component 60 is used to drive the two sliding massage components 30 back to their initial positions.

[0076] In this embodiment, the reset component 60 can be an elastic element, such as a tension spring. The two ends of a reset component 60 are respectively connected between a pair of sliding massage components 30 at the same height in the left and right rows of massage structures. For example, one end of the reset component 60 can be connected to the support portion 322 of the left sliding massage component 30, and the other end can be connected to the support portion 322 of the adjacent right sliding massage component 30.

[0077] Its working principle is as follows: In the initial state, i.e., when the massage function is not used, the sliding massage components 30 on both sides are at the starting position of their movement trajectory, and the reset component 60 is in its natural length or slightly pre-stretched state. When the user operates the armrest 41 to drive the sliding massage components 30 on both sides to perform massage movements, the sliding massage components 30 on both sides will move away from each other, thereby stretching the reset component 60 and storing elastic potential energy. When the user stops applying the driving force (e.g., releasing the armrest), the elastic potential energy stored in the reset component 60 will be released, generating a restoring force that pulls the two sliding massage components 30 closer to each other. Under the action of this restoring force, the two sliding massage components 30 are automatically driven to return to their initial position along their respective guide components 20, without requiring additional manual reset operation by the user.

[0078] This design not only simplifies operation and enhances the user experience, but also ensures that the device returns to standby mode after each use, ready for the next use.

[0079] In one embodiment, the armrest 41 includes a support portion 412 and a drive arm 413 connected to each other. The support portion 412 and the drive arm 413 are connected to the backrest 10 via a pivot. The main transmission member 421 is connected to the end of the drive arm 413 away from the pivot.

[0080] In this embodiment, the support portion 412 is a part of the armrest 41 designed for the user to place their arm. The user activates and controls the massage function by applying force to the support portion 412 (e.g., swinging inward or outward).

[0081] The drive arm 413 is the part of the handrail 41 that is mainly responsible for transmitting the movement of the support part 412 to the flexible transmission member 42 (specifically the main transmission member 421). The drive arm 413 can be an arm-shaped structure that extends downward, backward, or at other suitable angles from the support part 412.

[0082] The support portion 412 and the drive arm 413 (or, in other words, at an intermediate position of the armrest 41) are connected to the backrest 10 via a pivot. The armrest 41 is capable of rotating (e.g., swinging in the horizontal plane) relative to the backrest 10 about this pivot. This pivot point constitutes the fulcrum for the movement of the armrest 41.

[0083] The main drive component 421 is connected to the end of the drive arm 413 away from the pivot.

[0084] When a user applies a force to the support 412 to rotate it about the pivot, the end of the drive arm 413 moves in the opposite direction due to leverage. Because the main drive member 421 is connected to the end of the drive arm 413 away from the pivot, the movement of that end effectively pulls or releases the main drive member 421, thereby driving the entire massage assembly.

[0085] Through the pivotal connection between the armrest 41 and the backrest 10 and the fixed connection between the armrest 41 and the main drive component 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 drive component 421.

[0086] Therefore, by designing the armrest 41 to include a support portion 412 and a drive arm 413, and connecting the armrest 41 (specifically between the support portion 412 and the drive arm 413) to the backrest 10 via a pivot, and connecting the main transmission member 421 to the end of the drive arm 413 away from the pivot, the massage device of this embodiment enables the user to drive the massage components with smooth movements, thereby improving the comfort and driving efficiency of operation.

[0087] In one specific embodiment, the pivotal connection between the armrest 41 and the backrest 10 can be achieved through a pivoting connector, such as a rotating angle iron 45. One side of the rotating angle iron 45 can be fixed to the backrest 10. The other side of the rotating angle iron 45 is pivotally connected to the middle of the armrest 41 via a pin or other revolute joint. In this way, the armrest 41 can swing smoothly around the pivot point formed by this rotating angle iron 45.

[0088] In one specific embodiment, a vertical through hole 43 may be provided on the rotating angle iron 45. The vertical portion of the main transmission component 421 passes through the through hole 43. The through hole 43 provides preliminary constraint and guidance on the vertical position of the main transmission component 421, preventing it from undergoing excessive lateral displacement during transmission.

[0089] A guide structure 44 is provided in front of the drive arm 413 of the armrest 41, i.e., closer to the user. This guide structure 44 has a slot with a smooth inner wall. Its core function is to change the direction of movement of the main drive member 421. After the vertical portion of the main drive member 421 passes through the through hole 43 on the rotating angle iron 45, it continues downward and enters the guide structure 44, where it smoothly changes from a vertical to an approximately horizontal direction within the slot. Finally, the approximately horizontal portion of the main drive member 421, extending from the guide structure 44, is fixedly connected to the end of the drive arm 413 away from the rotating angle iron 45.

[0090] When the user swings the support portion 412 of the armrest 41, the armrest 41 rotates around the rotating angle iron 45. The end of the drive arm 413 swings accordingly. Since the horizontal portion of the main transmission member 421 is fixed to the end of the drive arm 413, the swinging of the drive arm 413 will directly pull the horizontal portion of the main transmission member 421.

[0091] The tension or displacement is transmitted to the vertical portion of the main drive member 421 via the guide structure 44. The vertical portion of the main drive 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-drive members 422 and the sliding massage assembly 30 connected thereto.

[0092] This dual-guide and limiting design ensures that the flexible transmission component 42 can always move along the predetermined path, effectively avoiding problems such as slackness, shaking, entanglement, or interference with other components during the transmission process, thus guaranteeing direct, stable, and efficient force transmission.

[0093] Through the aforementioned specific pivot structure and the multi-point limiting and guiding structure 44 of the main transmission component 421, the massage device of this embodiment not only achieves labor-saving and efficient lever drive, but also ensures the stability and reliability of the transmission process, thereby improving the user experience and product durability.

[0094] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model 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 this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
