[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following is for reference. Figures 1-8 A massage component 100 according to a first aspect embodiment of the present invention is described.

[0036] like Figures 5-8 As shown, the massage assembly 100 according to the first aspect of the present invention includes: a massage head 10, a drive shaft 20, and a telescopic mechanism 30.

[0037] Specifically, such as Figure 7 and Figure 8 As shown, the drive shaft 20 extends in the front-to-back direction and is connected to the massage head 10, which drives the massage head 10 to rotate about the axis of the drive shaft 20; the telescopic mechanism 30 is connected between the drive shaft 20 and the massage head 10, and the telescopic mechanism 30 drives the massage head 10 to be in an extended position relative to the drive shaft 20 in the front-to-back direction (e.g., Figure 2 , Figure 4 , Figure 6 and Figure 8 The location of the massage head 10 shown) and the retracted position (e.g.) Figure 1 , Figure 3 , Figure 5 and Figure 7 The massage head 10 moves between the positions shown in the diagram, and the massage head 10 in the extended position is located in front of the massage head 10 in the retracted position.

[0038] In some examples, refer to Figure 4 and Figure 8As shown, the massage head 10 can be provided with multiple massage protrusions 12 arranged at intervals. When the drive shaft 20 drives the massage head 10 to rotate, the massage protrusions 12 can move and rotate. Thus, through the multi-point contact of multiple massage protrusions 12, a three-dimensional massage surface can be formed, increasing the contact area with the body. At the same time, the staggered pressing sensation produced by the multiple massage protrusions 12 arranged at intervals can simulate the touch of finger kneading, which can more accurately stimulate muscle acupoints, improve the sense of massage and comfort, and avoid local discomfort caused by prolonged pressing of a single massage protrusion 12, making the massage effect more even and comprehensive.

[0039] like Figure 3 and Figure 4 As shown, at least two of the multiple massage protrusions 12 have different heights in the front-to-back direction; in other words, the front edges of at least two massage protrusions 12 are not aligned. This creates a three-dimensional massage dimension in the front-to-back direction, allowing for differentiated stimulation of muscles and acupoints at different depths. Higher massage protrusions 12 can penetrate deeper into muscles to relieve soreness, while lower massage protrusions 12 can gently massage superficial tissues to promote blood circulation. This makes the massage more targeted, enhances the depth and comfort of the massage, and strengthens the overall massage effect.

[0040] In some examples, such as Figure 4 and Figure 8 As shown, the telescopic mechanism 30 is connected between the drive shaft 20 and the massage head 10. Specifically, the massage head 10, the telescopic mechanism 30, and the drive shaft 20 are arranged sequentially from front to back. The telescopic mechanism 30 is located in front of the drive shaft 20 and behind the massage head 10. The front end of the telescopic mechanism 30 is fixedly connected to the massage head 10, and the rear end of the telescopic mechanism 30 is fixedly connected to the front end of the drive shaft 20. Thus, during the rotation of the drive shaft 20, the drive shaft 20 can drive the telescopic mechanism 30 to rotate, and the telescopic mechanism 30 in turn drives the massage head 10 to rotate.

[0041] The telescopic mechanism 30 is extendable in the front-to-back direction; in other words, its length in the front-to-back direction is adjustable or variable. The telescopic mechanism 30 drives the massage head 10 to move in the front-to-back direction by extending and retracting. For example, the telescopic mechanism 30 can be an electric push rod, or it can include a motor and a lead screw drive structure.

[0042] When the drive shaft 20 rotates, power is transmitted to the massage head 10 through the telescopic mechanism 30, causing the massage head 10 to rotate. When the massage head 10 needs to be extended, the telescopic mechanism 30 pushes the massage head 10 forward in the front-back direction until it reaches the extended position, at which point the massage protrusions 12 of the massage head 10 can contact the human body for massage. When the massage head 10 needs to be retracted, the telescopic mechanism 30 can drive the massage head 10 to move backward, causing the massage head 10 to return to the retracted position, detaching it from the human body and reducing space occupation.

[0043] In this embodiment, the extension and retraction stroke of the massage head 10 can be precisely controlled by the telescopic mechanism 30, achieving dynamic adjustment so that it precisely conforms to the massage area of ​​the human body when extended and is fully retracted when retracted. This not only avoids collision damage caused by prolonged exposure of the massage head 10, but also allows for adjustment of the massage head 10's position in the front-back direction during use, adapting to the back curves of users of different body types and improving massage fit. Furthermore, when the massage component 100 of this embodiment is used in a seat, the telescopic mechanism 30 drives the massage head 10 to the extended and retracted positions, enabling the seat to flexibly switch between massage mode and normal seating mode. This expands the seat's usage scenarios, ensuring both the professionalism of the massage effect and the comfort and space utilization of daily use.

[0044] According to the embodiments of the present invention, the massage component 100 is connected between the massage head 10 and the drive shaft 20 by a telescopic mechanism 30. The telescopic mechanism 30 can drive the massage head 10 to move in the front and back direction. Thus, the telescopic stroke of the massage head 10 can be precisely controlled, so that the massage head 10 fits the human body when it extends and is adapted to different body shapes. When the massage head 10 is retracted, it is stored to avoid collision damage. It can also make the seat flexibly switch between massage mode and sitting mode, expanding the usage scenarios of the seat.

[0045] In some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, in the front-to-back direction, the massage head 10 moves a distance of 15mm-40mm between the extended position and the retracted position. For example, the distance the massage head 10 moves between the extended position and the retracted position can be 15mm, 18mm, 20mm, 22mm, 25mm, 28mm, 30mm, 32mm, 35mm, 38mm, or 40mm, etc.

[0046] Furthermore, refer to Figure 7 and Figure 8As shown, in the front-back direction, the massage head 10 moves a distance of 20mm-30mm between the extended position and the retracted position. For example, the distance the massage head 10 moves between the extended position and the retracted position can be 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm or 30mm.

[0047] This embodiment ensures that the massage head 10 moves 15mm-40mm between the extended and retracted positions, thus guaranteeing full contact with the human body when extended and providing appropriate pressure depth for different parts of the body, avoiding insufficient pressure. At the same time, it effectively reduces space occupation when the massage head 10 is retracted, adapting to various seating scenarios. This achieves a balance between massage effect and space utilization, meeting the needs of users of different body types for massage intensity and seating comfort.

[0048] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the telescopic mechanism 30 includes an airbag 31, which is connected between the drive shaft 20 and the massage head 10. The airbag 31 has an air chamber and an air port (not shown) communicating with the air chamber. The air port is adapted to be connected to an air source. The airbag 31 has an inflated state and an empty state. When the airbag 31 is inflated, the massage head 10 is in the extended position. When the airbag 31 is in the empty state, the massage head 10 is in the retracted position.

[0049] The deflation state of the airbag 31 includes a fully deflated state and a partially deflated state. When the airbag 31 is fully deflated, the gas inside the airbag 31 is completely extracted, and there is no gas inside the airbag 31. When the airbag 31 is partially deflated, the gas inside the airbag 31 is partially extracted, and some gas remains inside the airbag 31.

[0050] Specifically, when the massage head 10 needs to extend, an air source (such as an air pump) inflates the air chamber of the airbag 31 through an air inlet, causing the airbag 31 to expand. Since the airbag 31 is connected between the drive shaft 20 and the massage head 10, the thrust generated by the expansion of the airbag 31 can push the massage head 10 forward in the front-back direction until it reaches the extended position. Figure 4 As shown, the massage protrusions 12 of the massage head 10 can contact the human body for massage at this time. When it is necessary to retract the massage head 10, the air source stops supplying air and the gas in the air chamber is vented through the air port. After the airbag 31 loses its air pressure support, it contracts and returns to its original position. Under the pulling force of the contracting airbag 31, the massage head 10 moves backward in the front-back direction and returns to the retracted position, as shown. Figure 3 As shown, the massage head 10 detaches from the human body and retracts into the seat.

[0051] It should be noted that, in this embodiment, the movement distance of the massage head 10 in the front-to-back direction can be precisely adjusted by controlling the inflation and deflation of the airbag 31, thereby achieving on-demand extension and retraction.

[0052] The telescopic mechanism 30 in this embodiment includes an airbag 31. When inflated, the airbag 31 expands evenly to generate thrust, ensuring a smooth and impact-free extension of the massage head 10. It adapts to the curves of the human body, reducing discomfort from hard contact. When deflated, the airbag 31 naturally contracts, gently retracting the massage head 10 and reducing mechanical wear. Simultaneously, the airbag 31 provides elastic cushioning, preventing rigid collisions between the massage head 10 and the human body or seat structure, thus improving safety. Furthermore, the airbag 31 has a simple structure, low cost, and low noise during inflation and deflation, thereby enhancing the user experience.

[0053] In some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the airbag 31 is a multi-layered compression airbag 31. Specifically, the multi-layered compression airbag 31 refers to an airbag structure composed of multiple layers of materials stacked or combined. When inflated, the multi-layered compression airbag 31 expands layer by layer, providing more uniform thrust; when deflated, it can be compressed and folded in multiple layers, reducing storage space. Compared to a single-layered airbag 31, the multi-layered structure enhances the airbag 31's pressure resistance, elasticity, and durability, adapting to frequent inflation and deflation scenarios and extending the lifespan of the massage component 100.

[0054] like Figure 7 and Figure 8 As shown, the airbag 31 includes multiple airbag units connected sequentially in the front-to-back direction. Each airbag unit defines a sub-cavity on its inner side, and the sub-cavities of the multiple airbag units are interconnected.

[0055] In some embodiments of this utility model, the airbag 31 can be a rubber part, a composite fiber part, a thermoplastic polyurethane part, or a silicone part.

[0056] In some embodiments of this utility model, the airbag 31 is a thermoplastic polyurethane elastic element. By setting the airbag 31 as a thermoplastic polyurethane elastic element, this embodiment can make the airbag 31 have better elasticity, improve the wear resistance and anti-aging performance of the airbag 31, and make the airbag 31 adaptable to frequent inflation and deflation, thereby extending the service life of the airbag 31.

[0057] In some embodiments of this utility model, reference is made to Figure 8As shown, the air vent is formed on the side of the airbag 31 layer furthest from the massage head 10 in the front-back direction, opposite to the massage head 10. In other words, the massage head 10 is connected to the front of the airbag 31, and the air vent is located on the rear of the airbag 31. Therefore, when inflating or deflating the airbag 31 through the air vent, the massage head 10 can be prevented from directly squeezing the air vent during movement, protecting the stability and reliability of the air circuit connection. It can also reduce interference between the airbag 31 and the gas pipeline connected to the air vent when the airbag 31 expands or contracts, and facilitate the layout of the gas pipeline.

[0058] In some embodiments of this utility model, such as Figures 1-4 As shown, the massage assembly 100 also includes a drive motor 41, which is connected to the drive shaft 20 and is used to drive the drive shaft 20 to rotate so as to drive the massage head 10 to rotate. The massage assembly 100 is configured to inflate the airbag 31 when the drive motor 41 is started and to deflate the airbag 31 when the drive motor 41 is stopped.

[0059] Specifically, when the drive motor 41 starts, the drive shaft 20 rotates, causing the massage head 10 to rotate. Simultaneously, the control system triggers the air source to inflate the airbag 31. The inflated airbag 31 pushes the massage head 10 to extend to its working position, allowing the rotating massage head 10 to massage the body. When the drive motor 41 stops, the massage head 10 stops rotating. Simultaneously, the control system controls the airbag 31 to deflate, causing it to contract and retract the massage head 10. This achieves synchronized control of the massage head 10's rotation and extension / retraction, resulting in convenient operation and a high degree of automation.

[0060] In this embodiment, by linking the drive motor 41 with the airbag 31, the massage head 10 can be started and stopped synchronously when rotating and extending. In this way, when starting, it inflates, extends and rotates for massage, and when stopping, it deflates and retracts. This avoids the massage head 10 being exposed and damaged when idle. At the same time, the linkage design simplifies the operation process, enhances the automation experience, and ensures that the massage function is activated as needed. This optimizes the safety of use and reduces the space occupation and mechanical wear when not in use.

[0061] In some embodiments of this utility model, such as Figure 7 and Figure 8As shown, the massage head 10 includes a disc body 11 and multiple massage protrusions 12. The disc body 11 is connected to the airbag 31 and is located on the side of the airbag 31 facing away from the drive shaft 20 in the front-back direction. The multiple massage protrusions 12 are arranged at intervals on the disc body 11, and all protrude towards the side facing away from the airbag 31. In this embodiment, by connecting the disc body 11 to the airbag 31 and setting it away from the drive shaft 20, the massage protrusions 12 can face towards the human body, ensuring that the massage protrusions 12 can directly contact the massage area when the massage head 10 is extended. The multiple massage protrusions 12 arranged at intervals can form a three-dimensional massage surface. With the rotation of the disc body 11, it can simulate kneading action, increasing the contact area while precisely stimulating muscle acupoints through staggered pressing, thereby improving the massage comfort and sense of layering.

[0062] In some embodiments of this utility model, reference is made to Figure 8 As shown, the massage protrusion 12 is formed as a hollow structure, defining a cavity facing the opening of the airbag 31, which is connected to the air chamber. In this embodiment, by forming the massage protrusion 12 as a hollow structure, the amount of material used in the massage protrusion 12 can be reduced, lowering costs, reducing the weight of the massage head 10, reducing the load on the telescopic mechanism 30 and the drive motor 41, and improving overall transmission efficiency. Furthermore, since the hollow massage protrusion 12 is connected to the air chamber of the airbag 31 through the cavity, when the airbag 31 is inflated, the cavity of the massage protrusion 12 can be simultaneously filled with gas. This enhances the hardness and pressure of the massage protrusion 12, and by changing the air pressure within the cavity, the massage intensity can be dynamically adjusted. This allows the massage protrusion 12 to produce a buffered pressure when in contact with the human body, reducing hard stimulation and improving massage comfort.

[0063] In some embodiments of this utility model, such as Figure 8 As shown, the disc body 11 and the airbag 31 are formed as a single unit. This reduces the number of parts, improves assembly efficiency, enhances the connection reliability between the disc body 11 and the airbag 31, and also improves the sealing performance between the disc body 11 and the airbag 31.

[0064] In some embodiments of this utility model, such as Figure 8 As shown, the thickness of the disc body 11 is greater than or equal to 3 mm. For example, the thickness of the disc body 11 can be 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, or 6 mm, etc. This can enhance the structural strength and rigidity of the disc body 11, reduce the risk of deformation or damage to the disc body 11 when subjected to external forces, and extend the service life of the massage head 10.

[0065] In some embodiments of this invention, the massage head 10 is made of plastic. This not only reduces the weight of the massage head 10 and lowers the energy consumption of the telescopic mechanism 30 and the drive motor 41, but also improves the wear resistance of the massage head 10 and reduces costs.

[0066] In some embodiments of this utility model, such as Figure 8 As shown, one end of the drive shaft 20 is provided with a connecting flange 21. The massage assembly 100 also includes a connecting plate 50, which is connected to the connecting flange 21 by fasteners. One end of the airbag 31 is connected to the connecting plate 50. In this embodiment, by connecting the connecting flange 21 of the drive shaft 20 to the connecting plate 50 by fasteners, the drive shaft 20 can be rigidly fixed to the airbag 31 through the connecting plate 50. This allows the drive shaft 20 to stably and reliably drive the massage head 10 to rotate through the connecting plate 50 and the airbag 31 during rotation. At the same time, it also facilitates the assembly and maintenance of the airbag 31 and the drive shaft 20, and makes it convenient to repair and replace components such as the airbag 31 and the massage head 10. In addition, when the airbag 31 of the telescopic mechanism 30 is inflated and deflated, the connecting plate 50 can evenly distribute the thrust during inflation and deflation, avoiding local deformation of the drive shaft 20 and improving the reliability of the massage assembly 100.

[0067] In some embodiments of this utility model, such as Figure 8 As shown, the connecting plate 50 and the airbag 31 are formed as a single piece. This reduces the number of parts, improves assembly efficiency, and enhances the reliability of the connection between the connecting plate 50 and the airbag 31.

[0068] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the massage assembly 100 also includes a drive mechanism 40, which includes a drive motor 41 and a transmission assembly. The drive motor 41 is connected to the drive shaft 20 via the transmission assembly and is used to drive the drive shaft 20 to rotate. There are two drive shafts 20, which are respectively arranged on opposite sides of the drive mechanism 40. The telescopic mechanism 30 and the massage head 10 are connected to the drive shaft 20 in a one-to-one correspondence. There can be two transmission assemblies, with the drive motor 41 connected to the two drive shafts 20 via two transmission assemblies, and the two drive shafts 20 respectively driving the two massage heads 10 to rotate. Further, the two drive shafts 20 and the corresponding massage heads 10 can be arranged on the left and right sides of the drive motor 41, respectively.

[0069] In this embodiment, the drive motor 41 simultaneously drives two drive shafts 20 to rotate, which can synchronously drive two massage heads 10 to rotate. This allows the massage intensity of the two massage heads 10 to be consistent and also increases the massage coverage area.

[0070] A seat according to a second aspect of the present invention includes: a seat body and a massage component 100 according to the first aspect of the present invention, wherein the massage component 100 is disposed on the seat body.

[0071] According to the embodiments of the present invention, the seat is equipped with a massage component 100 as described in the first aspect embodiment. The massage component 100 is provided with a telescopic mechanism 30 connected between the massage head 10 and the drive shaft 20. The telescopic mechanism 30 can drive the massage head 10 to move in the front and back direction. Thus, the telescopic stroke of the massage head 10 can be precisely controlled, so that the massage head 10 fits the human body when it extends and is adapted to different body shapes. When the massage head 10 is retracted, it is stored to avoid collision damage to the massage head 10. It can also make the seat flexibly switch between massage mode and sitting mode, expand the use scenarios of the seat, and thus improve the overall performance of the seat.

[0072] The following will refer to Figures 1-4 A massage component 100 according to a specific embodiment of the present invention is described.

[0073] Reference Figures 1-4 The massage component 100 includes: a massage head 10, a drive shaft 20, a telescopic mechanism 30, a connecting plate 50, and a drive mechanism 40. The drive mechanism 40 includes a drive motor 41 and two transmission components, respectively arranged on the left and right sides of the drive motor 41. The connecting plate 50, telescopic mechanism 30, drive shaft 20, and massage head 10 are all in pairs, corresponding one-to-one. The drive motor 41 is connected to the two drive shafts 20 via the two transmission components. The drive shafts 20 are connected to the telescopic mechanism 30 via the connecting plate 50. The massage head 10 is connected to the front side of the telescopic mechanism 30.

[0074] Specifically, the massage head 10 is made of plastic and includes a disc body 11 and multiple massage protrusions 12. The disc body 11 is a flat plate arranged perpendicular to the front-back direction and has a thickness of 3mm. Figure 3 and Figure 4 As shown, there are four massage protrusions 12, wherein the front end face of the massage protrusion 12 is a forward-convex spherical surface, and at least two of the massage protrusions 12 have different protrusion heights in the front-back direction.

[0075] The drive shaft 20 includes a main shaft and a connecting flange 21. The main shaft extends in a front-rear direction, and the connecting flange 21 is connected to the front end of the main shaft. A plurality of first fastening holes are formed on the connecting flange 21 at circumferential intervals. Further, the drive shaft 20 is a metal part.

[0076] The connecting plate 50 is a flat plate arranged perpendicular to the front-back direction. Multiple second fastening holes are formed on the connecting plate 50 at intervals. The multiple first fastening holes and multiple second fastening holes correspond one-to-one and are opposite to each other in the front-back direction. The connecting plate 50 and the connecting flange 21 are fixedly connected by fasteners passing through the first fastening holes and the second fastening holes.

[0077] The telescopic mechanism 30 includes an airbag 31 and an air pump (not shown). An air chamber is defined inside the airbag 31, and an air port is formed on the airbag 31. The air pump is connected to the air port and is used to pump gas into the air chamber through the air port and to extract gas from the air chamber. The airbag 31 is a multi-layered compression airbag 31, for example... Figure 4 As shown, the airbag 31 is a two-layer compressed airbag 31. Further, the airbag 31 is a thermoplastic polyurethane elastic element. Further, the airbag 31 is integrally formed with the connecting plate 50 and the disc body 11 of the massage head 10.

[0078] The airbag 31 has an inflated state and a deflated state. When inflated, the airbag 31 expands and moves the massage head 10 forward to the extended position. When deflated, the airbag 31 contracts and folds, and moves the massage head 10 backward to the retracted position.

[0079] The massage component 100 of this embodiment can adjust the position of the massage head 10 in the front-to-back direction via the airbag 31. When the drive mechanism 40 is powered on, the airbag 31 inflates, and the massage protrusion 12 moves forward; simultaneously, the drive motor 41 drives the drive shaft 20 to rotate, and the drive shaft 20 drives the airbag 31 and the massage head 10 to rotate for massage. When the drive mechanism 40 stops, the airbag 31 deflates, and the massage protrusion retracts.
