Description

Technical Field

[0001] This invention relates to the technical field of massage equipment, and more specifically to a massage device. Background Technology

[0002] Massage devices such as fascia guns currently only allow adjustment of vibration frequency and speed, not independent control of vibration amplitude. This fixed-amplitude fascia gun has extremely poor adaptability. For example, fitness enthusiasts with high tolerance require deep, penetrating massage, while small amplitudes cannot loosen deep fascia; while for the elderly, children, patients in rehabilitation, and those with weak muscles, fixed large amplitudes can easily cause muscle impact injuries. Therefore, traditional fascia guns cannot meet the needs of different groups and body parts, nor can they satisfy users' refined massage requirements, resulting in insufficient core competitiveness. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the main objective of the present invention is to provide a massage device that addresses the problem that traditional massage devices cannot meet the usage needs of different people and body parts.

[0004] To achieve the above objectives, the present invention provides a massage device comprising: The outer casing has an opening on one side; A massage assembly includes a massage head movably disposed within the housing, one end of the massage head protruding outside the opening and having a linear reciprocating stroke moving toward and away from the opening; A drive assembly, disposed within the housing, includes a drive motor and a transmission structure. The transmission structure connects the drive motor and the massage assembly. The transmission structure includes an eccentric wheel and a connecting rod structure. The connecting rod structure connects the eccentric wheel and the massage head. The drive motor drives the eccentric wheel to rotate and moves the transmission structure, so that the massage head moves linearly back and forth in a direction toward or away from the opening. A stroke adjustment component is disposed on the housing and connected to the transmission structure; The linkage structure includes multiple linkages that are sequentially hinged together to form a connection start end and a connection end end. The connection start ends of the multiple linkages are connected to the eccentric part of the eccentric wheel, and the connection ends of the multiple linkages are connected to the massage head. The stroke adjustment component is connected to the hinge of two of the linkages and is used to adjust the included angle between the two linkages to adjust the distance by which the massage head extends out of the opening.

[0005] Optionally, the linkage structure includes a first linkage and a second linkage, one end of the first linkage is eccentrically hinged to the eccentric wheel, the other end of the first linkage is hinged to one end of the second linkage, and the other end of the second linkage is hinged to the massage head; the stroke adjustment component is hinged at the hinge point of the first linkage and the second linkage.

[0006] Optionally, the hinge joint between the first link and the second link is used to form a first hinge portion; The stroke adjustment assembly includes an adjustment block and an adjustment rod. The adjustment block is movably mounted on the housing. The two ends of the adjustment rod are respectively connected to the adjustment block and the first hinge portion. The adjustment block can move relative to the housing to adjust the distance between the first hinge portion and the opening.

[0007] Optionally, the direction of movement of the massage head, the direction of extension of the rotation axis of the first hinge, and the direction of movement of the adjustment block are all perpendicular to each other.

[0008] Optionally, the stroke adjustment assembly further includes an adjustment member, which is rotatably mounted on the housing and connected to the adjustment block; the adjustment member rotates relative to the housing under the action of an external force, which can drive the adjustment block to move toward or away from the massage head, so that the first hinge portion can move toward or away from the opening.

[0009] Optionally, the adjusting member is configured as an adjusting screw, which is screwed to the adjusting block. The extending direction of the adjusting screw is perpendicular to the moving direction of the massage head and the extending direction of the rotation axis at the hinge of the first connecting rod and the second connecting rod.

[0010] Optionally, the housing is provided with a guide groove, the adjusting block is slidably disposed in the guide groove, one end of the adjusting screw is screwed to the adjusting block, and the other end of the adjusting screw is located outside the housing.

[0011] Optionally, the massage head includes: A massage rod is inserted into the opening, and one end is hinged to the second connecting rod; The massage end is located at the other end of the massage rod and outside the opening; The travel adjustment component is used to adjust the travel of the massage end relative to the opening.

[0012] Optionally, the end of the massage rod is provided with a groove, and the second connecting rod and the adjusting rod are hinged in the groove.

[0013] Optionally, the direction of the rotation shaft of the drive motor, the extension direction of the adjusting screw, and the movement direction of the massage head are all perpendicular to each other.

[0014] The technical solution provided by this invention has the following beneficial effects: The massage device provided by this invention includes a housing, a massage component, a drive component, and a stroke adjustment component. The front end of the massage head extends out of the opening of the housing. By reciprocating linearly relative to the opening, the massage head's front end can reciprocate on the user's skin and muscle layer, relaxing tense muscles and deep fascia, thereby achieving a massage effect. Specifically, a drive motor drives an eccentric wheel to rotate, which, under the transmission of a linkage structure, drives the massage head to reciprocate linearly relative to the opening. This converts the rotation of the drive motor into the linear reciprocating movement of the massage head, allowing for a more compact arrangement of the massage component and drive component, resulting in a smaller massage device. Furthermore, the stroke adjustment component is connected to the linkage hinge of the transmission structure, allowing adjustment of the angle between the two linkages, thereby adjusting the distance the massage head extends out of the opening. This allows for adjustment of the massage head's stroke relative to the opening, thus adjusting the depth of the massage head's application to the user's skin to meet the massage needs of different users. The massage device can better adapt to the needs of different users by adjusting the massage depth, has a wider range of applications, and can better meet users' refined massage needs.

[0022] This invention provides a massage device 100. For details, please refer to [link / reference needed]. Figures 1 to 2In this embodiment, the massage device 100 includes a housing 1, a massage component 2, a drive component 3, and a stroke adjustment component 4. An opening is provided on one side of the housing 1. The massage component 2 includes a massage head 21 movably disposed within the housing 1. One end of the massage head 21 protrudes outside the opening and has a linear reciprocating stroke moving towards and away from the opening. The drive component 3 is disposed within the housing 1 and includes a drive motor 31 and a transmission structure 32. The transmission structure 32 connects the drive motor 31 and the massage component 2. The transmission structure 32 includes an eccentric wheel 321 and a connecting rod structure 322. The connecting rod structure 322 connects the eccentric wheel 321 and the massage head 21. The drive motor 31 drives the eccentric wheel 321 to rotate, thereby moving the transmission structure 32, so that the massage head 21 moves linearly reciprocally towards or away from the opening. The stroke adjustment component 4 is disposed on the housing 1 and connected to the transmission structure 32. The linkage structure 322 includes multiple linkages that are hinged together in sequence to form a connection start end and a connection end end. The connection start ends of the multiple linkages are connected to the eccentric part of the eccentric wheel 321, and the connection ends of the multiple linkages are connected to the massage head 21. The stroke adjustment component 4 is connected to the hinge of two of the linkages and is used to adjust the included angle between the two linkages to adjust the distance of the massage head 21 extending out of the opening.

[0023] In this embodiment, the end of the massage head 21 facing the user is its front end. The front end of the massage head 21 can extend out of the opening of the outer shell 1, and the massage head 21 moves linearly back and forth relative to the opening. This allows the front end of the massage head 21 to reciprocate on the user's skin and muscle layer to relax the user's tense muscles and deep fascia, thereby achieving a massage effect. Specifically, the drive motor 31 drives the eccentric wheel 321 to rotate, and under the transmission action of the connecting rod structure 322, it drives the massage head 21 to move linearly back and forth relative to the opening. This realizes the conversion of the rotational motion of the drive motor 31 into the linear reciprocating motion of the massage head 21, making the arrangement of the massage component 2 and the drive component 3 more compact, and the size of the massage device 100 smaller. Moreover, the stroke adjustment component 4 is connected to the connecting rod hinge of the transmission structure 32 to adjust the included angle between the two connecting rods, thereby adjusting the distance of the massage head 21 extending out of the opening. This allows the adjustment of the amount of travel of the massage head 21 relative to the opening, thereby adjusting the depth of the massage head 21 acting on the user's skin to meet the massage needs of different users. The massage device 100 can better adapt the massage depth to the needs of different users, making it more widely applicable and better able to meet users' refined massage needs.

[0024] The shape of the outer shell 1 is not specifically limited; it can be roughly cylindrical, T-shaped, or 7-shaped. In one embodiment, when the outer shell 1 is roughly cylindrical, one axial end of the outer shell 1 is used for the user to hold, and the massage head 21 is disposed at the other axial end of the outer shell 1. In this case, the vibration direction of the massage head 21 is consistent with the axial direction of the outer shell 1, and the massage device is arranged in a straight line, which makes it easier to store.

[0025] Preferably, combined with Figure 1 As shown, the outer shell 1 is roughly in the shape of a "7". The outer shell 1 includes a first shell segment 11 and a second shell segment 12, both of which are roughly cylindrical. The first shell segment 11 and the second shell segment 12 are connected and perpendicular to each other. The first shell segment is for the user to hold, and the drive motor 31 is located inside the first shell segment 11. The massage component 2 is located inside the second shell segment 12. The direction of movement of the massage head 21 is set as the first direction, and the direction of extension of the rotation shaft of the drive motor 31 is set as the second direction, which is perpendicular to the first direction. This arrangement avoids the overall length of the massage device 100 from being too long in one direction, thus preventing inconvenience for the user.

[0026] Furthermore, the outer casing 1 includes a first half-shell and a second half-shell arranged symmetrically. The first half-shell and the second half-shell are detachably connected, and the connection hole between the adjusting member 43 and the outer casing 1 is located precisely at the mating point of the first half-shell and the second half-shell. During assembly, the drive assembly 3, the stroke adjustment assembly 4, and the massage assembly 2 can all be assembled into one of the first half-shell and the second half-shell first, and then the other half-shell can be closed. This provides more operating space during assembly, is not limited by the narrow space inside the outer casing 1, and makes assembly more convenient and efficient.

[0027] It is understood that the travel adjustment component 4 can be driven to move by a drive device to achieve automatic travel adjustment. At this time, the massage device 100 may also include a controller and an adjustment button. The controller is electrically connected to both the drive device and the adjustment button. The adjustment button sends a command to the controller, which in turn controls the drive device to adjust the position of the travel adjustment component 4. The adjustment button can be a mechanical button, a touchscreen button, and / or a hand sensor. For example, the adjustment button may include three levels: level 1, level 2, and level 3. Level 1 is the minimum travel level of the massage head 21, and level 3 is the maximum travel level. By moving the adjustment button to the corresponding level, the travel adjustment component 4 can be moved to the corresponding position under the drive of the drive device, thus adjusting the travel of the massage head 21 more intelligently and effortlessly.

[0028] Of course, the movement of the travel adjustment component 4 can also be adjusted manually by the user, which reduces the number of internal parts of the massage device 100. On the one hand, it saves more space, and on the other hand, it eliminates the need for a drive device to drive the travel adjustment component 4, thus reducing costs.

[0029] When the stroke adjustment component 4 is subjected to an external force, it can generate at least a third-direction movement, in which the third-direction is perpendicular to both the first and second directions.

[0030] Understandably, there are many ways to configure the linkage structure 322. The linkage structure 322 may include one or more linkages. The number of linkages can be reasonably set according to the size of the massage device 100.

[0031] Preferably, combined with Figure 2 and Figure 3 As shown, the linkage structure 322 includes a first linkage 3221 and a second linkage 3222. One end of the first linkage 3221 is eccentrically hinged to the eccentric wheel 321, and the other end of the first linkage 3221 is hinged to one end of the second linkage 3222. The other end of the second linkage 3222 is hinged to the massage head 21. The stroke adjustment assembly 4 is hinged at the hinge point of the first linkage 3221 and the second linkage 3222. The rotation of the eccentric wheel 321 drives the first linkage 3221 and the second linkage 3222 to rotate simultaneously. Due to the eccentric connection, the first linkage 3221 and the second linkage 3222 can simultaneously form a radial travel along the eccentric wheel 321. Furthermore, the opening guides and restricts the massage head 21, allowing the second linkage 3222 to drive the massage head 21 to reciprocate linearly relative to the opening. The reciprocating vibration of the massage head 21 relative to the opening allows it to act on the user's skin, thus providing a massage effect.

[0032] Further, the articulated joint of the first link 3221 and the second link 3222 forms a first articulated portion. The stroke adjustment assembly 4 includes an adjustment block 41 and an adjustment rod 42. The adjustment block 41 is movably arranged on the housing 1. The two ends of the adjustment rod 42 are respectively connected to the adjustment block 41 and the first articulated portion. When the adjustment block 41 moves relative to the housing 1, the distance between the first articulated portion and the opening can be adjusted. When the distance between the first articulated portion and the opening changes, the stroke of the massage head 21 extending out of the opening will also change accordingly. For example, when the distance between the first articulated portion and the opening is L1, the maximum displacement of the massage head 21 extending out of the opening is S1; by driving the adjustment block 41 to move in a direction away from the central axis of the massage head 21, so that the distance between the first articulated portion and the opening is L2. At this time, L2 > L1, and the maximum displacement of the massage head 21 extending out of the opening becomes S2, and S2 < S1. On the contrary, if the adjustment block 41 is driven to move in a direction close to the central axis of the massage head 21, so that the distance between the first articulated portion and the opening is L3, then at this time, L3 < L1, and the maximum displacement of the massage head 21 extending out of the opening becomes S3, and S3 > S1.

[0033] Preferably, the moving direction of the massage head 21, the extending direction of the rotation axis at the articulated joint of the first link 3221 and the second link 3222, and the moving direction of the adjustment block 41 are perpendicular to each other pairwise. This makes the moving paths of the massage head 21, the first link 3221 and the second link 3222, and the moving path of the adjustment block 41 not interfere with each other, effectively avoiding motion interference and ensuring stable and smooth operation of the mechanism; at the same time, the motion strokes in each direction can be independently designed and flexibly configured, greatly expanding the overall motion range and enhancing the motion freedom and adjustment ability of the mechanism.

[0034] The number of the above-mentioned links can be reasonably set according to the change of the size of the massage device 100. In an embodiment, multiple groups of the above-mentioned link structures 322 can be provided to be adapted to multiple massage heads 21 for use. For example, three groups of symmetrically arranged link structures 322 are used with the massage heads 21. Each group of first links 3221 is articulated to the same eccentric wheel 321, and the three groups of massage heads 21 are evenly distributed along the linear slide rail. During operation, the rotation of the eccentric wheel 321 drives the three groups of link structures 322 to move synchronously, and the three groups of massage heads 21 vibrate reciprocally at the same time, with a larger coverage range of the massage effect, enabling the massage device 100 to better adapt to the massage of large-area parts such as the back and waist, and significantly improving the massage efficiency compared with the single-group structure.

[0035] It can be understood that the movement of the adjustment block 41 can be directly or indirectly pushed by the user. Preferably, in combination with Figure 2 and Figure 5As shown, the stroke adjustment assembly 4 also includes an adjustment member 43, which is rotatably mounted on the housing 1 and connected to the adjustment block 41. At least a portion of the adjustment member 43 is exposed on the outside of the housing 1. When the adjustment member 43 is subjected to an external force, it rotates relative to the housing 1, which can drive the adjustment block 41 to move toward or away from the massage head 21, so that the first hinge portion can move toward or away from the opening. By rotating the adjustment member 43, the user can drive the adjustment block 41 to generate a stroke in a third direction, thereby adjusting the relative position of the massage head 21 and the opening.

[0036] Furthermore, the adjusting component 43 is configured as an adjusting screw 431, which is screwed to the adjusting block 41. The extension direction of the adjusting screw 431 is perpendicular to the movement direction of the massage head 21 and the extension direction of the rotation axis at the hinge of the first connecting rod 3221 and the second connecting rod 3222. That is, the adjusting screw 431 extends along a third direction, and a lead screw and nut structure can be formed between the adjusting screw 431 and the adjusting block 41, so that the adjusting screw 431 can adjust the adjusting block 41 with higher precision and quieter operation, thereby making the adjustment precision of the stroke of the massage head 21 higher and better meeting the different usage needs of users.

[0037] Furthermore, a guide groove is provided inside the outer casing 1, and the adjusting block 41 is slidably disposed in the guide groove. One end of the adjusting screw 431 is screwed to the adjusting block 41, and the other end of the adjusting screw 431 is located outside the outer casing 1. The movement of the adjusting block 41 can be restricted by the guide groove, so that the adjusting block 41 can move more smoothly in a straight line along the third direction, and avoid the adjusting block 41 from deviating and causing the first connecting rod 3221 and the second connecting rod 3222 to jam.

[0038] Preferably, the direction of the rotation shaft of the drive motor 31, the extension direction of the adjusting screw 431, and the movement direction of the massage head 21 are all perpendicular to each other. The rotation shaft of the drive motor 31 is coaxially arranged with the eccentric wheel 321. The drive motor 31 is directly connected to the eccentric wheel 321, and then connected to the eccentric wheel 321 through the connecting rod structure 322. The movement direction is changed through the connecting rod structure 322, so as to convert the rotation of the eccentric wheel 321 into the linear reciprocating movement of the massage head 21. This results in higher transmission efficiency and a simple and compact structure.

[0039] For the massage component 2, it is mainly used to connect directly or indirectly to the linkage structure 322, so that the rotational motion of the eccentric wheel 321 can be converted into the linear reciprocating movement of the massage head 21. Among these, combined with... Figure 4 and Figure 5As shown, the massage head 21 includes a massage rod 211 and a massage end 212. The massage rod 211 passes through the opening and is hinged at one end to the second connecting rod 3222. The massage end 212 is located at the other end of the massage rod 211 and is situated outside the opening. The massage rod 211 is generally cylindrical and is movably fitted into the opening. A sleeve is also provided within the second housing section 12, fixed to the end of the second housing section 12 near the opening. The massage rod 211 is movably fitted into the sleeve, which provides a guiding fit. This ensures that when the massage rod 211 moves, the sleeve restricts its movement, allowing the massage rod 211 to only reciprocate along a first direction. The massage end 212 is located at the other end of the massage rod 211 and is generally spherical, with its spherical surface contacting the user's skin for improved comfort.

[0040] Furthermore, the massage device 100 also includes a battery assembly, which is electrically connected to the drive motor 31 to provide the power required for the drive motor 31 to operate. The battery assembly is located inside the first housing section 11 and on the side of the drive motor 31 facing away from the eccentric wheel 321. By placing both the battery assembly and the drive motor 31 at the end of the housing 1 where the user can hold it, the weight of the massage device is closer to the hand, and the user's hand does not need to exert extra force to counteract the forward tilting torque of gravity during use, making operation more effortless. A charging interface electrically connected to the battery assembly is also provided on the outer wall of the housing 1, through which the battery assembly can be charged.

[0041] like Figure 5 As shown, a groove 2121 is provided at the end of the massage rod 211, and the second connecting rod 3222 and the adjusting rod 42 are hinged in the groove 2121. On the one hand, the structure is more compact, and on the other hand, the movement of the massage rod 211 along the first direction is better restricted and it is not easy to deviate.

[0042] The massage device 100 can be configured as a fascia gun, neck massager, waist massager, or massage chair, etc.

[0043] Specifically, when the massage device 100 is in operation, the drive motor 31 drives the eccentric wheel 321 to rotate. The eccentric wheel 321 drives the first connecting rod 3221, which is hinged to it, to rotate together, thereby driving the second connecting rod 3222 to move. This allows the second connecting rod 3222 to have a travel in the first direction, which in turn drives the massage rod 211 and the massage end 212 to move together in the first direction. Moreover, when the user needs to adjust the vibration stroke of the massage device 100, they can manually rotate the screw acting on the adjusting member 43. Since the adjusting screw 431 is screwed to the adjusting block 41, the rotation of the adjusting screw 431 drives the adjusting block 41 to move along the adjusting screw 431, thereby driving the first hinge part to move towards or away from the opening, thereby adjusting the relative distance between the massage end 212 and the opening, changing the travel of the massage end 212 from the opening, and thus adjusting the massage depth acting on the user's skin, so as to better meet the different usage needs of users and improve the applicability of the massage device 100.
