Description

Technical Field

[0001] The utility model belongs to the field of massage devices, and particularly relates to a leg massage mechanism and a massage chair. Background Art

[0002] At present, massage chairs can generally be divided into two major structural components, namely a leg massage structure and a back massage structure.

[0003] Regarding the leg massage structure, most of them drive the massage structures at different positions through two drive motors. For example, when the inner side of the calf needs to be massaged, the corresponding motor drives the middle massage mechanism to massage. Similarly, when the sole needs to be massaged, the sole massage structure can be started by the corresponding motor. However, this method not only fails to achieve a good massage effect on the leg muscles, but also cannot guarantee the coordination when the leg muscle massage mechanism rubs the inside of the calf, affecting the comfort of the user. At the same time, this massage mechanism uses more components, resulting in a more complex overall structure. While increasing the weight of the massage mechanism, it also makes the components prone to damage, thereby shortening the service life of this massage mechanism. Summary of the Utility Model

[0004] Aiming at the above deficiencies existing in the prior art, the technical problem to be solved by the utility model is to provide a leg massage mechanism and a massage chair.

[0005] The technical solution adopted by the utility model to solve its technical problems is to provide a leg massage mechanism, including: a mounting frame configured with a rotating shaft;

[0011] In the above-mentioned leg massage mechanism, the driving component further includes:

[0012] An installation cover, connected to the mounting frame,

[0014] A worm gear, arranged on the rotating shaft, and the worm gear is movably meshed with the worm, so that when the worm gear rotates, it can drive the rotating shaft to rotate synchronously.

[0015] In the above-mentioned leg massage mechanism, a fixed shaft is connected to the bottom end of the moving part close to the mounting frame. A fixed guide sleeve placed vertically is provided on the mounting frame, and the end of the fixed shaft is movably clamped in the fixed guide sleeve.

[0016] In the above-mentioned leg massage mechanism, an installation groove is formed at the top end of each fixed guide sleeve, and the opening direction of the installation groove is inclined, so that the end of the fixed shaft can pass through the installation groove and be movably clamped in the fixed guide sleeve, and the height of the fixed guide sleeve in the vertical direction is greater than the maximum stroke of the fixed shaft moving in the fixed guide sleeve.

[0017] In the above-mentioned leg massage mechanism, the massage block includes a main body part, a connecting part and a massage part. The connecting part and the massage part are distributed at both ends of the main body part. A second connection hole is formed in the connecting part, and the second connection hole is movably sleeved on the second eccentric wheel; a plurality of raised blocks are formed on the massage part, and the raised blocks can scrape the muscles of the leg when the main body part moves.

[0018] In the above-mentioned leg massage mechanism, fixed seats are further arranged on both sides of the mounting frame. An arc-shaped guiding groove is formed in the fixed seats.

[0021] The technical solution adopted by the present invention to solve its technical problems is to further propose a massage chair, including a leg massage mechanism as described above.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) In the leg massage mechanism and the massage chair of the present invention, the first eccentric wheel and the second eccentric wheel are arranged on the same rotating shaft. Then, under the drive of the drive assembly, by the eccentric rotation of the first eccentric wheel, the movement of the moving portion realizes the kneading of the inner side of the calf. At the same time, under the eccentric rotation of the second eccentric wheel, the massage block realizes the scraping function of the leg muscles. Thus, under the unified drive of the rotating shaft, the coordination of the kneading and scraping actions of the two massage structures at different positions is effectively improved, ensuring that the use requirements of customers can be met. At the same time, this massage mechanism also reduces the use of drive motors and rotating shafts, greatly saving the use of components, avoiding the phenomenon of frequent replacement due to component damage, reducing the overall weight while also extending the service life.

[0024] (2) By movably clamping both ends of the guiding shaft in the arc-shaped guiding groove, on the one hand, the arc-shaped guiding groove is used to prevent the connecting portion from falling off during movement, and on the other hand, it can also play a guiding and limiting effect on the movement direction of the massage block during scraping, improving the smoothness and stability of the operation of this massage mechanism.

[0035] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0036] As Figure 1 shown, in this solution, a leg massage mechanism for a massage chair is mainly described in detail. However, this leg massage mechanism is not limited to being used in a massage chair and can also be applied to other places, such as a massage bucket in daily life.

[0037] As Figures 1 to 5As shown in the figure, a leg massage mechanism includes: a mounting frame 1 configured with a rotating shaft 10; a fixed part 20 and a moving part 21 disposed on the mounting frame 1. The fixed part 20 is located on both sides of the moving part 21 and forms a placement groove 22 with the moving part 21. The placement groove 22 can accommodate the leg to be massaged; a driving assembly 3 is disposed on the mounting frame 1 and connected to the rotating shaft 10. The driving assembly 3 includes a first eccentric wheel 30 eccentrically disposed on the rotating shaft 10. The bottom end of the moving part 21 close to the mounting frame 1 is movably clamped on the mounting frame 1, and the top end is movably sleeved on the first eccentric wheel 30; a second eccentric wheel 4 and a massage block 5. The second eccentric wheel 4 is coaxially and eccentrically disposed on the rotating shaft 10 with the first eccentric wheel 30; the massage block 5 is movably disposed on the mounting frame 1 and extends into the bottom of the placement groove 22. One end of the massage block 5 is movably sleeved on the second eccentric wheel 4, and the other end is movably clamped in the mounting frame 1; when the driving assembly 3 drives the rotating shaft 10 to rotate, the moving part 21 can realize the kneading of the inner side of the leg under the eccentric rotation of the first eccentric wheel 30; at the same time, the massage block 5 can scrape the muscles of the leg under the eccentric rotation of the second eccentric wheel 4.

[0038] This scheme is mainly aimed at calf massage. Specifically, when the user places both legs into the corresponding placement grooves 22, the muscles on the calves (referred to as the calf area of ​​the calves) are pressed against the bottom wall of the placement grooves 22. Therefore, when the driving component 3 drives the rotating shaft 10 to rotate, the first eccentric wheel 30 and the second eccentric wheel 4 can be driven to rotate eccentrically synchronously. It is worth noting that since the top end of the movable part 21 close to the mounting frame 1 in the present scheme is movably sleeved on the first eccentric wheel 30, the movable part 21 can be swung when the first eccentric wheel 30 rotates eccentrically. In addition, the bottom end of the movable part 21 close to the mounting frame 1 is movably connected to the mounting frame 1, which can ensure that the movable part 21 will not be separated from the mounting frame 1 when it moves, thereby improving the stability of the structure, and can also play a role in giving way when the movable part 21 swings, thereby effectively preventing the movable part 21 from getting stuck during movement. Preferably, in the present solution, air bags (not shown in the figure) are connected to both sides of the movable part 21, so as the movable part 21 swings, the inner side of the leg can be rubbed; at the same time, since the second eccentric wheel 4 is coaxially arranged with the first eccentric wheel 30, during the rotation of the above-mentioned rotating shaft 10, the second eccentric wheel 4 also rotates eccentrically, and under the same working principle as the above-mentioned movable part 21, the massage block 5 can scrape the leg muscles when it moves; that is, the present solution utilizes the rotation of the rotating shaft 10, and can simultaneously utilize the first eccentric wheel 30 and the second eccentric wheel 4 to respectively realize the kneading and scraping actions, thereby improving the coordination of the structure when performing relaxation actions on various parts of the leg, ensuring that the relaxation needs of the user can be met, and at the same time, the massage mechanism also reduces the use of the drive motor 32 and the rotating shaft 10, greatly saving the use of components, avoiding the phenomenon that components are damaged and need to be frequently replaced, reducing the overall weight while also extending the service life.

[0039] The top of the movable portion 21 close to the mounting frame 1 is connected with a first mounting seat 210 and a second mounting seat 211 which are detachable from each other. The first mounting seat 210 and the second mounting seat 211 jointly form a first connecting hole 212 which is movably sleeved on the first eccentric wheel 30 .

[0040] like Figures 1 to 3 As shown, during the installation process, the first mounting seat 210 and the second mounting seat 211 are aligned and abutted against each other, so that the first eccentric wheel 30 can be placed in the first connecting hole 212 formed by the first mounting seat 210 and the second mounting seat 211. At the same time, the limiting protrusions (not shown in the figure) formed on both sides of the first mounting seat 210 and the second mounting seat 211 are used to limit the first eccentric wheel 30 to a certain extent, effectively preventing the first eccentric wheel 30 from driving the first mounting seat 210 and the second mounting seat 211 to move. Relative displacement in the axial direction will be generated, thereby ensuring the stability of the structure during operation.

[0041] Preferably, the first connection hole 212 and the first eccentric wheel 30 in this solution are not in an interference fit. That is to say, the first mounting seat 210 and the second mounting seat 211 will only move in the direction perpendicular to the axis of the rotation shaft 10 due to the eccentric rotation of the first eccentric wheel 30. Combined with the fact that the bottom end of the moving part 21 is movably clamped on the mounting frame 1, when the first eccentric wheel 30 is driven, it can drive the whole moving part 21 to perform an elliptical trajectory cyclic motion to achieve the kneading effect on the inner side of the leg.

[0042] A fixed shaft 214 is connected to the bottom end of the side of the moving part 21 close to the mounting frame 1. A fixed guide sleeve 12 is arranged on the mounting frame 1 in the vertical direction, and the end of the fixed shaft 214 is movably clamped in the fixed guide sleeve 12.

[0043] Furthermore, as Figure 3 shown, the fixed guide sleeve 12 is detachably connected to the mounting frame 1 in the vertical direction through screws and other fixing parts, which provides convenience for subsequent replacement and maintenance; different from the conventional guide sleeve, a through groove 121 is opened on the side wall of the fixed guide sleeve 12 in this solution, so that the fixed shaft 214 on the moving part 21 can pass through the through groove 121 and be movably clamped in the fixed guide sleeve 12. Due to the fitting method of this structure's movable clamping, when the above-mentioned first eccentric wheel 30 rotates eccentrically, both ends of the fixed shaft 214 can reciprocate along the vertical direction of the fixed guide sleeve 12 to provide space for the whole moving part 21 to move in an elliptical trajectory, avoiding jamming when the moving part 21 kneads the inner side of the leg and ensuring that the user experience is not affected.

[0044] Preferably, continue to refer to Figure 3 , in this solution, an installation groove 120 is opened at the top end of each fixed guide sleeve 12, and the opening direction of the installation groove 120 is inclined. On the one hand, it can effectively prevent the fixed shaft 214 from moving out of the fixed guide sleeve 12 when reciprocating along the vertical direction of the fixed guide sleeve 12, improving the stability of the moving part 21 during kneading; on the other hand, it is convenient for the end of the fixed shaft 214 to pass through the installation groove 120 smoothly and be movably clamped in the fixed guide sleeve 12, providing convenience for workers during installation and disassembly. In addition, the height of the fixed guide sleeve 12 in the vertical direction in this solution is slightly greater than the maximum stroke of the fixed shaft 214 moving in the fixed guide sleeve 12, further avoiding the phenomenon of the fixed shaft 214 moving out or even jamming in the fixed guide sleeve 12.

[0045] The massage block 5 includes a main body portion 50, a connecting portion 51, and a massage portion 52. The connecting portion 51 and the massage portion 52 are distributed at both ends of the main body portion 50. The connecting portion 51 is formed with a second connecting hole 510, and the second connecting hole 510 is movably sleeved on the second eccentric wheel 4. A plurality of protruding blocks 520 are formed on the massage portion 52, and the protruding blocks 520 can scrape the leg muscles when the main body portion 50 moves.

[0046] As Figure 1 , Figures 4 to 5 shown, the massage block 5 in this solution is composed of three parts: the main body portion 50, the connecting portion 51, and the massage portion 52. However, it should be noted that each part can scrape the calf when moving. In addition, the connecting portion 51 mainly plays a role of being movably sleeved and connected with the second eccentric wheel 4. This connection method is the same as the installation method between the above-mentioned first mounting seat 210 and the second mounting seat 211, and the working principle is also the same, so it will not be elaborated here in detail. The main body portion 50 plays a connecting role, enhancing the overall strength of the massage block 5 and the area of scraping the calf. When the second eccentric wheel 4 makes an eccentric rotation, the whole massage block 5 can be driven to make a reciprocating movement through the connecting portion 51. At this time, the protruding blocks 520 can achieve a better scraping effect on the calf.

[0047] Preferably, the massage portion 52 in this solution is integrally arranged in a T shape, and the protruding blocks 520 in this solution are arranged in a triangular shape on the massage portion 52, so that when the massage block 5 moves, the protruding blocks 520 can achieve an effect similar to that of a user scraping with fingers, thereby enhancing the customer experience. In addition, an L-shaped reinforcing rib (not marked in the figure) is also provided on the T-shaped massage portion 52 to enhance the overall structural strength of the massage portion 52.

[0048] Fixed seats 11 are also provided on both sides of the mounting bracket 1. An arc-shaped guiding groove 110 is formed in the fixed seat 11. A guiding shaft 500 is installed at the bottom of the connection between the main body portion 50 and the massage portion 52, and both ends of the guiding shaft 500 are movably clamped in the arc-shaped guiding groove 110.

[0049] As Figure 4 and Figure 5 shown, in order to ensure the effect of the massage block 5 scraping the calf in a circulating manner, an arc-shaped guiding groove 110 is formed in the fixed seat 11. By using the guiding shaft 500 to be movably clamped in the arc-shaped guiding groove 110, it plays a certain guiding and limiting effect when the massage block 5 moves. This structure is the same as the principle and the effect brought by the above-mentioned fixed shaft 214 and the fixed guide sleeve 12, so it will not be elaborated one by one here.

[0050] Preferably, an arc-shaped block 511 is further formed on the connecting portion 51 in this solution. When the second eccentric wheel 4 eccentrically rotates to push the massage block 5 to reciprocate, the arc-shaped block 511 can be used to cooperate with the convex block 520 on the above-mentioned massage portion 52, effectively enhancing the scraping function of the massage block 5 on the leg muscles and ensuring that the relaxation effect required by the user can be achieved.

[0051] The second eccentric wheel 4 includes a first mounting block 40 and a second mounting block 41 both arranged on the rotating shaft 10. Fixed wheels 42 are arranged on both the first mounting block 40 and the second mounting block 41. The fixed wheels 42 are not coaxially arranged with the first mounting block 40 and the second mounting block 41. The connecting portion 51 is movably sleeved on the two mutually abutting fixed wheels 42.

[0052] As Figure 5 shown, before the first mounting block 40 and the second mounting block 41 are mounted on the rotating shaft 10, the connecting portion 51 is movably sleeved on one of the fixed wheels 42 in advance. When the first mounting block 40 and the second mounting block 41 approach each other and the two fixed wheels 42 abut against each other, the connecting portion 51 can be movably connected to the second eccentric wheel 4. The overall structure is relatively simple, providing convenience for subsequent maintenance and replacement. At the same time, by using the design method that the outer diameters of the first mounting block 40 and the second mounting block 41 are larger than the outer diameter of the connecting portion 51, the connecting portion 51 is effectively prevented from disengaging from the second eccentric wheel 4, improving the stability of the structure.

[0053] The driving assembly 3 further includes: a mounting cover 31 connected to the mounting frame 1, a driving motor 32 and a worm 33. A receiving cavity 213 is formed in the moving portion 21. The driving motor 32 is connected to the outer wall of the mounting cover 31 and is located in the receiving cavity 213; the worm 33 is rotatably arranged in the mounting cover 31 and is connected to the output end of the driving motor 32; a worm gear 34 is arranged on the rotating shaft 10, and the worm gear 34 is movably engaged with the worm 33, so that when the worm gear 34 rotates, the rotating shaft 10 can be driven to rotate synchronously.

[0054] As Figure 2 With Figure 3 shown, the driving motor 32 is located in the receiving cavity 213 and will not interfere with the movement of the moving portion 21, greatly saving the space occupied by the components. Therefore, when the driving motor 32 is turned on, by driving the worm 33 to rotate, the synchronous rotation of the worm gear 34 and the rotating shaft 10 can be realized. Finally, under the synchronous eccentric rotation of the first eccentric wheel 30 and the second eccentric wheel 4, the kneading of the inner side of the leg and the scraping function of the leg are respectively realized. The two actions operate synchronously and coordinately, reducing the use of the driving motor 32 and the rotating shaft 10, avoiding the phenomenon of frequent replacement due to component damage, and ensuring that the massage mechanism can bring the relaxation effect required by the user.

[0055] Preferably, there are two sets of the first eccentric wheel 30, the fixed guide sleeve 12, the first mounting seat 210 and the second mounting seat 211 in the present solution, which are symmetrically placed to ensure the smoothness and stability when the moving part 21 rubs the inner side of the calf along an elliptical trajectory.

[0056] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0057] In addition, in the present invention, descriptions such as "first", "second", "one" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0058] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0059] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
