Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a roller-rocker type calf and knee contour massage mechanism. Background Technology

[0002] In the field of leg massage, existing technologies often focus on massaging the thighs, calves, or feet, but targeted massage designs for the popliteal fossa (back of the knee) are relatively scarce. However, the popliteal fossa contains important blood vessels and nerves, and is also the location of several acupoints (such as the Weizhong acupoint). Effective massage can significantly promote blood circulation in the legs and relieve knee joint fatigue and discomfort. Some current solutions attempt to address this deficiency, but they often have limitations. For example, some designs use an additional independent motor to drive the massage rollers in the popliteal fossa, which, while achieving the function, increases structural complexity and cost. Other solutions, while offering multiple massage functions, may be bulky and not compact enough, or fail to achieve synergistic operation between popliteal fossa massage and massage of other parts of the calf.

[0003] Furthermore, many existing massage devices require multiple motors to drive massage mechanisms for different areas, leading to complex control, increased power consumption, and higher manufacturing costs. Therefore, the market urgently needs a compact, energy-efficient solution that can provide coordinated and precise massage for the back of the knee and calves. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a roller-type calf and knee-back contour massage mechanism. Through a clever linkage mechanism, power is simultaneously transmitted to the knee-back kneading mechanism and the calf scraping mechanism, effectively solving the above-mentioned pain points.

[0005] This utility model discloses a roller-rocker type calf and knee-back contour massage mechanism, including a calf support, on which a scraping massage component and a knee-back massage component are provided. The knee-back massage component includes a roller rotatably mounted on the calf support and a roller rotatably mounted on the roller. The scraping massage component includes a massage seat guided and slidable on the calf support and a scraping tool mounted on the massage seat. A drive motor is provided on the calf support, and a roller rotating synchronously with the roller is provided on the roller. The output shaft of the drive motor is linked with the roller. The roller is further provided with a rocker arm rotating synchronously with it, and a rocker arm is hinged to the rocker arm. The other end of the rocker arm is hinged to the massage seat.

[0006] A further feature of this invention is that the roller has several mounting shafts arranged along the circumferential direction, and each mounting shaft is equipped with a roller, with the rollers rotatably mounted on the corresponding mounting shaft.

[0007] A further feature of this invention is that the two ends of the scraping tool are arc-shaped to form guide surfaces, and massage bumps are provided on the guide surfaces. A scraping block is provided on the scraping tool between the two guide surfaces, and the scraping block gradually decreases in size from both sides to the center.

[0008] A further feature of this invention is that the roller is a rotating body formed by a curve, with raised sections on both sides and in the middle to form a scraping and massaging area, and the remaining parts of the rotating body raised and lower than the scraping and massaging area to form a kneading area.

[0009] A further feature of this invention is that the scraping tool is rotatably mounted on the massage seat.

[0010] A further feature of this invention is that a guide groove is provided on the calf support, and a guide block is provided in the corresponding guide groove of the massage seat. The guide block slides within the guide groove and is also provided with an anti-detachment structure.

[0011] Using the above technical solution, when the drive motor is working, the roller rotates, which in turn drives the drum to rotate. When the drum rotates, it drives the roller to rotate, thus massaging the back of the knee. This solves the problem of not being able to massage the back of the knee in existing products on the market. At the same time, the rotation of the roller drives the swing arm to rotate. Because the massage seat slides on the calf support, the rocker arm cannot rotate directly and instead forms an eccentric rocker arm structure that extends and retracts. This also drives the massage seat to slide and retract, allowing the scraping tool to perform the scraping function. One drive motor can drive the roller for rolling massage and also drive the scraping tool for scraping, reducing costs and simplifying the internal structure. Attached Figure Description

Detailed Implementation

[0013] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] This utility model discloses a roller-rocker type calf and knee-back contour massage mechanism, including a calf support 1, on which a scraping massage component 2 and a knee-back massage component 3 are provided. The knee-back massage component 3 includes a roller 31 rotatably mounted on the calf support 1 and a roller 32 rotatably mounted on the roller 31. The scraping massage component 2 includes a massage seat 21 guided and slidably mounted on the calf support 1 and a scraping tool 22 mounted on the massage seat 21. A drive motor 4 is provided on the calf support 1, and a roller 5 that rotates synchronously with the roller 31 is provided on the roller 31. The output shaft of the drive motor 4 is linked with the roller 5. In this utility model embodiment, a rocker arm 6 that rotates synchronously with the roller 5 is also provided on the roller 5. A rocker arm 7 is hinged on the rocker arm 6, and the other end of the rocker arm 7 is hinged to the massage seat 21.

[0015] Using the above technical solution, when the drive motor is working, the roller 5 rotates, which in turn drives the roller 31 to rotate. When the roller 31 rotates, it drives the roller 32 to rotate, thus massaging the back of the knee. This solves the problem of not being able to massage the back of the knee in existing products on the market. At the same time, when the roller 5 rotates, it drives the swing arm 6 to rotate. At this time, because the massage seat 21 slides on the lower leg support 1, the rocker arm 7 cannot rotate directly and forms an eccentric rocker arm structure to extend and retract. This also drives the massage seat 21 to extend and retract, at which point the scraping tool 22 can perform the scraping function. One drive motor can drive the roller 32 to perform rolling massage and also drive the scraping tool 22 to perform scraping, reducing costs and simplifying the internal structure.

[0016] The roller 31 has several mounting shafts 311 arranged along the circumferential direction. Each mounting shaft 311 is equipped with a roller 32, and the roller 32 is rotatably mounted on the corresponding mounting shaft 311. With this layout, multiple rollers can be set on one roller 31, which makes the massage effect better.

[0017] The two ends of the scraping tool 22 are arc-shaped to form guide surfaces 221, and massage protrusions 222 are provided on the guide surfaces 221. A scraping block 223 is provided on the scraping tool 22 between the two guide surfaces 221. The scraping block 223 gradually decreases in size from both sides to the middle. In this way, the lower leg can be more stably guided to the position of the scraping block 223 through the guide surfaces, and scraping massage can be performed through the scraping block 223. Moreover, the scraping block 223 with this layout has a better scraping effect.

[0018] The roller 32 is a curved rotating body with raised sides and middle to form a scraping and massaging section 321. The remaining part of the rotating body is raised and lower than the scraping and massaging section 321 to form a kneading section 322. When the roller 32 is rolled with this layout, it can achieve the massage effect of scraping and kneading.

[0019] The scraping tool 22 is rotatably mounted on the massage seat 21. This mounting method allows the scraping tool 22 to rotate without affecting its normal sliding scraping function, and the structural layout is relatively reasonable.

[0020] The lower leg support 1 is provided with a guide groove 11, and the massage seat 21 is provided with a guide block 211 in the corresponding guide groove 11. The guide block 211 slides within the guide groove 11 and is also provided with an anti-detachment structure. The cooperation between the guide block 211 and the guide groove 11 makes the massage seat 21 more stable when sliding. The anti-detachment structure is preferably a limiting piece. In this case, the guide groove 11 is a through groove, and the guide block 211 partially passes through the guide groove 11. The limiting piece is set on the guide block 211 that passes through the guide groove 11. When the guide block 211 is pulled out by force, the limiting piece abuts against the lower leg support 1 to form a limit. The guide block 211 is preferably fixed to the massage seat 21 by bolts or screws. Of course, a dovetail groove and a guide block can also be used to achieve anti-detachment.
