Abstract
Description
Technical Field
[0001] This utility model relates to the field of massage equipment technology, and in particular to a massage component and a seat having the same. Background Technology
[0002] Massage chairs are widely used in homes, offices, and public places, providing users with a comfortable massage experience. However, existing massage components typically employ a design where the massage head is fixedly connected to a drive shaft. While this achieves basic massage functions, its drawbacks are becoming increasingly apparent. Because the massage head is rigidly fixed to the drive shaft, its position cannot adaptively adjust to changes in the user's leaning pressure. When the user leans back too forcefully, the pressure applied by the massage head may exceed the body's tolerance, causing discomfort or even injury; conversely, when the leaning pressure is too light, the massage head cannot provide sufficient massage intensity, failing to achieve the desired relaxation effect. Utility Model Content

This avoids excessive pressure while maintaining massage intensity, enhancing the massage experience. Simultaneously, by setting a limiting element to restrict the movement distance of the massage protrusion, damage to the elastic element due to excessive deformation can be prevented, extending its service life. It also prevents excessive pressure on the body when the massage protrusion moves too far backward, improving massage comfort and safety. Furthermore, the controllable adjustment of the massage protrusion's stroke in the front-to-back direction ensures that the massage intensity remains within a reasonable range.

[0036] 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.
[0037] The following is for reference. Figures 1-6 A massage component 100 according to a first aspect embodiment of the present invention is described.
[0038] like Figures 4-6 As shown, the massage assembly 100 according to the first aspect of the present invention includes: a massage head 10 and a drive shaft 20.
[0039] Specifically, such as Figure 4As shown, the massage head 10 includes: a disc body 11, an elastic element 14, a massage protrusion 12, and a limiting element 15. The elastic element 14 is connected between the disc body 11 and the massage protrusion 12. The elastic element 14 can undergo elastic deformation in the front-back direction. The limiting element 15 is provided on the disc body 11 and / or the massage protrusion 12 to limit the maximum distance of relative movement between the massage protrusion 12 and the disc body 11 in the front-back direction. The drive shaft 20 extends in the front-back direction and is connected to the disc body 11 to drive the disc body 11 to rotate around the axis of the drive shaft 20.
[0040] In some examples, the disc 11 can be a flat plate perpendicular to the front-back direction, and the number of massage protrusions 12 can be one, two, three, four, five, six, seven, eight, or more. The drive shaft 20 is connected to the disc 11 of the massage head 10. When the drive shaft 20 drives the disc 11 to rotate, the massage protrusions 12 can rotate with the disc 11, allowing them to move and rotate. Multiple massage protrusions 12 can form multi-point contact, creating a three-dimensional massage surface, increasing the contact area with the body. The staggered pressing sensation produced by the spaced-out massage protrusions 12 simulates the kneading sensation of fingers, more precisely stimulating muscle acupoints, enhancing the layering and comfort of the massage, and avoiding localized discomfort caused by prolonged pressure from a single massage protrusion 12, resulting in a more even and comprehensive massage effect.
[0041] In some examples, the elastic element 14 can be a spring, an elastic rubber block, a spring sheet, or a bellows. The massage protrusion 12 is connected to the disc body 11 via the elastic element 14. When the elastic element 14 undergoes elastic deformation, the massage protrusion 12 can move relative to the disc body 11 in the front-back direction. In some examples, one or more elastic elements 14 can be connected between the massage protrusion 12 and the disc body 11. When there are multiple elastic elements 14, they can be arranged at intervals.
[0042] Since the elastic element 14 is connected between the massage protrusion 12 and the disc body 11, when the user leans against the massage component 100, the massage protrusion 12 is pressed backward along the front-back direction, squeezing the elastic element 14. The elastic element 14 undergoes elastic deformation, causing the massage protrusion 12 to adaptively shift backward to buffer excessive pressure. When the leaning force decreases, the elastic element 14 restores its deformation, pushing the massage protrusion 12 back to its original position. In this way, through deformation and repositioning, the elastic element 14 allows the massage protrusion 12 to dynamically adjust its position in the front-back direction according to the user's leaning force, which can avoid excessive pressure while ensuring massage intensity and improving the massage experience.
[0043] In some examples, the limiting member 15 may be provided only on the disc body 11, or only on the massage protrusion 12, or both the disc body 11 and the massage protrusion 12 may be provided with the limiting member 15. The limiting member 15 can be used to limit the maximum distance the massage protrusion 12 can move in the front-back direction. For example, the massage protrusion 12 is movable relative to the disc body 11 between a first position and a second position in the front-back direction. When the massage protrusion 12 is in the first position, the disc body 11 and the massage protrusion 12 abut against each other in the front-back direction through the limiting member 15 to limit the massage protrusion 12 from moving further backward. When the massage protrusion 12 is in the second position, the disc body 11 and the massage protrusion 12 abut against each other in the front-back direction through the limiting member 15 to limit the massage protrusion 12 from moving further forward, thereby limiting the distance the massage protrusion 12 can move.
[0044] For example, the limiting member 15 can be formed as a limiting protrusion. Specifically, the disc body 11 can be provided with a first limiting protrusion and a second limiting protrusion arranged at intervals in the front-back direction. The massage protrusion 12 is provided with a third limiting protrusion, which is located between the first limiting protrusion and the second limiting protrusion. When the massage protrusion 12 is in the first position, the first limiting protrusion and the third limiting protrusion abut against each other in the front-back direction. When the massage protrusion 12 is in the second position, the second limiting protrusion and the third limiting protrusion abut against each other in the front-back direction.
[0045] In this embodiment, by setting a limiting member 15, the maximum distance that the massage protrusion 12 can move in the front-back direction can be limited. This not only prevents the elastic member 14 from being damaged due to excessive deformation and extends the service life of the elastic member 14, but also avoids applying excessive pressure to the human body when the massage protrusion 12 moves too far backward, thus improving the comfort and safety of the massage. Furthermore, by setting the limiting member 15, the stroke of the massage protrusion 12 in the front-back direction can be adjusted and controlled, so that the massage intensity of the massage protrusion 12 is always within a reasonable range, thereby improving the massage experience.
[0046] According to the embodiments of the present invention, the massage component 100, by providing an elastic element 14 between the disc body 11 and the massage protrusion 12, allows the massage component 100 to adjust the front-back position of the massage protrusion 12 based on the user's leaning force during use. This enables the massage protrusion 12 to have a front-back adaptive function, ensuring that the massage protrusion 12 remains in close contact with the user at all times. This avoids excessive pressure while maintaining massage intensity and enhancing the massage experience. Simultaneously, by providing a limiting element 15 to restrict the movement distance of the massage protrusion 12, damage to the elastic element 14 due to excessive deformation can be prevented, extending the service life of the elastic element 14. It also prevents excessive pressure on the human body when the massage protrusion 12 moves too far backward, improving the comfort and safety of the massage. This makes the stroke adjustment of the massage protrusion 12 in the front-back direction controllable, ensuring that the massage intensity of the massage protrusion 12 is always within a reasonable range.
[0047] In some embodiments of this utility model, reference is made to Figures 2-4 As shown, the maximum distance that the massage protrusion 12 can move relative to the disc body 11 in the front-back direction is 5mm-10mm. For example, the maximum distance that the massage protrusion 12 can move relative to the disc body 11 in the front-back direction can be 5mm, 6mm, 7mm, 8mm, 9mm or 10mm, etc.
[0048] Since the massage protrusion 12 is connected to the disc body 11 via the elastic element 14, the maximum distance the massage protrusion 12 can move relative to the disc body 11 in the front-back direction is equal to the maximum deformation that the elastic element 14 can undergo in the front-back direction. Therefore, the maximum distance the massage protrusion 12 can move relative to the disc body 11 in the front-back direction is 5mm-10mm, indicating that the maximum deformation that the elastic element 14 can undergo in the front-back direction is 5mm-10mm.
[0049] It should be noted that when the maximum deformable deformation of the elastic element 14 in the front-back direction is too small, for example, when the maximum deformable deformation of the elastic element 14 is less than 5mm, the adaptive range of the massage protrusion 12 in the front-back direction is small. At this time, the massage protrusion 12 cannot conform well to the curve of the human body for massage, affecting the massage experience. When the maximum deformable deformation of the elastic element 14 in the front-back direction is too large, for example, when the maximum deformable deformation of the elastic element 14 is greater than 10mm, since the initial size of the elastic element 14 in the front-back direction is fixed, the larger the maximum deformable deformation of the elastic element 14, the greater the elastic force when the elastic element 14 is compressed to the maximum deformable state. At this time, it will cause the elastic element 14 to apply too much pressure on the massage protrusion 12, thereby causing excessive compression of the human body.
[0050] In this embodiment, by moving the massage protrusion 12 relative to the disc body 11 by a maximum distance greater than or equal to 5mm and less than or equal to 10mm in the front-back direction, the massage protrusion 12 can not only be adjusted in a self-adaptive manner to better fit the body curves of users with different body types and improve the massage experience, but also prevent the massage protrusion 12 from excessively squeezing the body, thus improving the safety of the experience and ensuring massage comfort.
[0051] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the disc body 11 has a mounting hole extending through it in the front-to-back direction. The massage head 10 extends in a columnar shape in the front-to-back direction and is slidably fitted into the mounting hole. In this embodiment, by slidably fitting the massage protrusion 12 into the mounting hole, the mounting hole guides the front-to-back movement of the massage protrusion 12, ensuring that the massage head 10 moves only in the front-to-back direction without deviation, ensuring accurate massage positioning, and ensuring uniform massage intensity. In addition, the slidable fitting of the massage protrusion 12 into the mounting hole also guides the elastic deformation of the elastic member 14, preventing the elastic member 14 from becoming skewed. Furthermore, the massage protrusion 12 passing through the mounting hole reduces the space occupied by the massage head 10 in the front-to-back direction, further compacting the structure of the massage head 10.
[0052] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the massage head 10 may further include a guide cylinder 13, which is connected to the rear side of the disc body 11 and extends in a ring shape along the circumference of the mounting hole. The massage protrusion 12 is slidably fitted into the inner side of the guide cylinder 13. The massage protrusion 12 may have a columnar structure extending back and forth, and the guide cylinder 13 is sleeved on the outer side of the massage protrusion 12 to achieve a sliding fit between the massage protrusion 12 and the guide cylinder 13. This improves the coaxiality between the guide cylinder 13 and the massage protrusion 12, preventing the massage protrusion 12 from shifting during back-and-forth movement and avoiding jamming during movement.
[0053] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the end of the guide cylinder 13 that is away from the massage protrusion 12 (e.g.) Figure 4 The rear end of the guide cylinder 13 shown is closed, and the elastic element 14 is disposed inside the guide cylinder 13. One end of the elastic element 14 (e.g., Figure 4 The front end of the elastic element 14 shown is fixed to the massage protrusion 12, and the other end of the elastic element 14 (e.g., Figure 4 The rear end of the elastic element 14 shown is connected to the closed end of the guide cylinder 13. For example, the elastic element 14 may abut between the closed end of the guide cylinder 13 and the massage protrusion 12.
[0054] In this embodiment, by closing the rear end of the guide cylinder 13, the guide cylinder 13 can cooperate with the massage protrusion 12 to define a receiving cavity separated from the external space. The elastic element 14 is arranged within the receiving cavity enclosed by the guide cylinder 13 and the massage protrusion 12. Thus, the guide cylinder 13 and the massage protrusion 12 can protect the elastic element 14, not only preventing the elastic element 14 from being subjected to external forces in the radial direction, but also allowing the guide cylinder 13 to guide the deformation of the elastic element 14, thereby ensuring that the elastic element 14 only deforms elastically along the axial direction (front-back direction), improving the stability of the front-back movement of the massage protrusion 12. It can also prevent the elastic element 14 from interfering with or colliding with external parts, extending the service life of the elastic element 14. In addition, the elastic element 14 is located inside the guide cylinder 13, which allows the elastic element 14 to make reasonable use of the space inside the guide cylinder 13 without occupying additional space, thereby making the structure of the massage assembly 100 more compact.
[0055] In some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the massage protrusion 12 includes a massage part 122 and a cylindrical part 123. The front surface of the massage part 122 is a spherical surface that protrudes forward. The cylindrical part 123 is a hollow cylinder and is connected to the rear side of the massage part 122. One end of the elastic member 14 is fitted into the cylindrical part 123.
[0056] In this embodiment, by setting the front surface of the massage part 122 as a raised spherical surface, the massage protrusion 12 can closely conform to the curves of the human body such as the shoulders, neck, waist, and back, increasing the massage contact area and improving the comfort and uniformity of the massage. By setting the cylindrical part 123 as a hollow cylinder, the weight of the massage protrusion 12 can be reduced, the amount of material used in the massage protrusion 12 can be reduced, and the cost can be lowered. In addition, the hollow cylindrical part 123 can provide space for the elastic element 14, reducing the space occupied by the massage assembly 100 in the front-back direction and further compacting the structure.
[0057] In some embodiments of this utility model, the inner side of the massage protrusion 12 is provided with a first protrusion extending in the front-rear direction, the inner side of the guide cylinder 13 is provided with a second protrusion extending in the front-rear direction, and the elastic element 14 is a spring, with one end of the elastic element 14 sleeved on the outside of the first protrusion and the other end sleeved on the outside of the second protrusion. By providing the first and second protrusions in this embodiment, on the one hand, it is convenient to fix both ends of the spring, improving the reliability of the connection between the spring and the disc body 11 and the massage protrusion 12, preventing the spring from loosening; on the other hand, it is convenient to position and assemble the elastic element 14, improving assembly efficiency; and on the other hand, the first and second protrusions can radially limit the spring and guide its elastic deformation, preventing the spring from tilting.
[0058] In some embodiments of this utility model, such as Figures 4-6As shown, a limiting member 15 is disposed on one of the guide cylinder 13 and the massage protrusion 12, and the other of the guide cylinder 13 and the massage protrusion 12 is provided with a limiting hole 131. For example, when the limiting member 15 is disposed on the guide cylinder 13, a limiting hole 131 is formed on the massage protrusion 12; when the limiting member 15 is disposed on the massage protrusion 12, a limiting hole 131 is formed on the guide cylinder 13. The limiting hole 131 extends in the front-rear direction, and the limiting member 15 is movably fitted into the limiting hole 131 in the front-rear direction.
[0059] In some examples, the massage protrusion 12 is movable relative to the disc body 11 in the front-back direction between a first position and a second position. When the massage protrusion 12 is in the first position, the limiting member 15 abuts against one side wall of the limiting hole 131 in the front-back direction, and when the massage protrusion 12 is in the second position, the limiting member 15 abuts against the other side wall of the limiting hole 131 in the front-back direction.
[0060] In this embodiment, by movably fitting the limiting member 15 within the limiting hole 131 in the front-back direction, it can not only precisely limit the maximum movement distance of the massage protrusion 12 in the front-back direction to adapt to different massage intensity requirements, but also the limiting hole 131 can provide a guiding function for the limiting member 15, ensuring that the limiting member 15 does not deviate when subjected to force, improving the stability of the limiting, and further ensuring the stability of the massage protrusion 12 during the front-back movement.
[0061] In some examples, the limiting hole 131 can be an elongated hole extending in the front-back direction, and the two opposite sidewalls of the limiting hole 131 in the front-back direction are arc-shaped cylindrical surfaces protruding in opposite directions. The portion of the limiting member 15 that fits into the limiting hole 131 can be cylindrical.
[0062] In some examples, buffer pads may be provided on the two side walls of the limiting hole 131 in the front-rear direction, and the massage protrusion 12 abuts against the buffer pads in both the first and second positions. In other examples, buffer pads may be wrapped around the outer peripheral surface of the limiting member 15. Thus, the buffer pads can provide a cushioning effect for the limiting member 15, preventing the limiting member 15 from directly impacting the two side walls of the limiting hole 131 in the front-rear direction, avoiding rigid collisions, and thereby improving the service life of the limiting member 15.
[0063] In some embodiments of this utility model, such as Figures 4-6As shown, the guide cylinder 13 is provided with a plurality of limiting holes 131 arranged at intervals along the circumference of the guide cylinder 13. There are multiple limiting members 15, each corresponding to one of the limiting holes 131. For example, the number of limiting holes 131 on the guide cylinder 13 can be two, three, four, five, six, or more. In this embodiment, by setting multiple limiting members 15 to cooperate one-to-one with multiple limiting holes 131, the massage protrusion 12 can be subjected to uniform force in the circumferential direction, avoiding displacement of the massage protrusion 12 due to unilateral limiting, thus improving the stability of the massage protrusion 12 during movement. Simultaneously, it can also reduce the collision and contact pressure between a single limiting member 15 and the inner wall of the limiting hole 131, extending the service life of the limiting member 15.
[0064] In some embodiments of this utility model, reference is made to Figure 5 and Figure 6 The limiting member 15 is a screw, and a fixing hole is formed on the cylindrical portion 123 of the massage protrusion 12. The limiting member 15 is threaded into the fixing hole. For example, the cylindrical portion 123 is cylindrical, and a fixing hole is formed in the cylindrical portion 123 that runs radially through the cylindrical portion 123. The limiting member 15 can be a stud or a screw. The screw head of the limiting member 15 is located radially inside the cylindrical portion 123, and the screw portion of the limiting member 15 is threaded into the fixing hole and extends into the limiting hole 131. This avoids the limiting member 15 interfering with the assembly between the massage protrusion 12 and the guide cylinder 13, improves assembly efficiency, simplifies the structure of the limiting member 15, and facilitates disassembly and replacement.
[0065] In other examples, the limiting member 15 can be a limiting post, and the limiting member 15 can be integrally formed with the post body 123.
[0066] In some embodiments of this utility model, such as Figure 5 As shown, a flange 112 extending rearward is formed around the periphery of the disc body 11, and the flange 112 extends in a ring shape along the circumference of the disc body 11. Thus, the flange 112 can enhance the structural strength of the periphery of the disc body 11, prevent the disc body 11 from deforming under stress, and improve the overall rigidity and durability of the massage head 10.
[0067] In some embodiments of this invention, the massage protrusion 12 is made of plastic, which reduces its weight and cost, and also facilitates its processing and molding. Furthermore, the disc body 11 and the guide cylinder 13 are integrally molded plastic parts. This reduces the weight of the massage head 10 and lowers its cost.
[0068] In some examples, a connecting groove is formed on the rear surface of the disc 11, and one end of the drive shaft 20 is fitted into the connecting groove. The cross-section of the connecting groove is non-circular in the projection plane perpendicular to the front-rear direction, and the cross-sectional shape of one end of the drive shaft 20 matches the cross-sectional shape of the connecting groove. Furthermore, a first connecting hole is formed on the disc 11, extending through the bottom wall of the connecting groove in the front-rear direction. A second connecting hole is formed on the end face of one end of the drive shaft 20. The second connecting hole is a threaded hole. The massage assembly 100 also includes fasteners that pass through the first connecting hole and are then threaded into the second connecting hole, thereby fixing the drive shaft 20 to the disc 11.
[0069] Furthermore, a raised connecting ring is formed on the rear surface of the disc body 11. The connecting ring extends in a ring shape along the circumference of the drive shaft 20, and a connecting groove is defined on the inner side of the connecting ring.
[0070] In some embodiments of this utility model, such as Figures 1-4 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 motor 41. The massage heads 10 are connected to the drive shafts 20 one by one. Alternatively, 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. In this embodiment, by simultaneously driving the two drive shafts 20 to rotate by the drive motor 41, the two massage heads 10 can be driven to rotate synchronously. Therefore, the massage intensity of the two massage heads 10 can be made consistent, and the massage coverage area can be increased.
[0071] 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.
[0072] According to the embodiment of the present invention, the seat includes a massage component 100 as described in the first aspect embodiment. The massage component 100 has an elastic element 14 positioned between the disc 11 and the massage protrusion 12. During use, when the user leans against the massage protrusion 12, the massage component 100 can adjust the front-to-back position of the massage protrusion 12 based on the user's leaning force. This allows the massage protrusion 12 to have a front-to-back adaptive function, ensuring it remains in close contact with the user at all times. This avoids excessive pressure while maintaining massage intensity, enhancing the massage experience. Simultaneously, by setting a limiting element 15 to restrict the movement distance of the massage protrusion 12, damage to the elastic element 14 due to excessive deformation can be prevented, extending its service life. It also prevents excessive pressure on the body when the massage protrusion 12 moves too far backward, improving massage comfort and safety. Furthermore, the travel distance of the massage protrusion 12 in the front-to-back direction is controllable, ensuring the massage intensity remains within a reasonable range, thereby improving the overall performance of the seat.
