For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] Regarding one aspect of the embodiments of this application, please refer to Figure 1 and Figure 2 A massage leg rest 10 is provided, comprising: a base 11, a drive assembly disposed within the base 11, a main drive shaft 13, and two massage components. The main drive shaft 13 is drivenly connected to the output end of the drive assembly to rotate around its own axis under the drive of the drive assembly. The two massage components are respectively mounted on the main drive shaft 13, one massage component for massaging the user's left leg and the other for massaging the right leg. Since the user's left and right legs are symmetrically distributed, the two massage components can also be symmetrically distributed.

[0030] Please refer to the reference. Figure 3 The massage assembly includes a massage head and a scraper 141. The massage head massages the user's legs by rotating, while the scraper 141 massages the user's legs by sliding. Specifically, the massage head is fixed on the main drive shaft 13. When the main drive shaft 13 is driven to rotate by the drive assembly, it drives the massage head to rotate. The massage head can be coaxially arranged with the main drive shaft 13, so that it rotates around its own axis under the drive of the main drive shaft 13. The scraper 141 is eccentrically and rotatably connected to the massage head, that is, the scraper 141 is rotatably connected to the massage head, and the axis of the scraper 141 is parallel to the axis of the massage head.

[0031] One of the base 11 and the scraper 141 is provided with a guide groove 151, and the other is provided with a guide post 152 that cooperates with the guide groove 151. Since the guide post 152 always slides within the guide groove 151, and the scraper 141 can rotate relative to the massage head, the scraper 141 will slide back and forth along the extension direction of the guide groove 151 under the constraint of the guide groove 151.

[0032] The guide groove 151 is configured to guide the scraper 141 to extend or retract into the base 11. Under the restriction of the guide groove 151, the scraper 141 extends out of the base 11 to different degrees during the movement, which can bring the user a massage experience of different intensities and make the user's massage experience better.

[0033] The aforementioned massage leg rest 10 controls the movement of both the massage head and the scraper 141 simultaneously via a drive assembly, adding a scraping experience to the massage. It is compact, space-saving, and easy to control, providing users with a richer massage experience. Furthermore, the base 11 and scraper 141 of the massage leg rest 10 are equipped with guide grooves 151 and guide posts 152. The guide grooves 151 restrict the movement path of the scraper 141, thereby controlling the extent to which the scraper 141 extends beyond the base 11 during movement, thus providing users with different levels of massage intensity and enhancing their massage experience. Simultaneously, the guide grooves 151 also allow the scraper 141 to retract into the base 11 after the massage. As for the massage head, its posture can be adjusted when the scraper 141 retracts into the base 11, ensuring that the massage head also retracts into the base 11.

[0034] Optionally, the massage head includes a massage head body 144 and a plurality of massage protrusions 145 spaced apart along the circumferential direction of the massage head body 144. The massage head body 144 is connected to the main drive shaft 13. During the movement of the massage head, the massage head body 144 remains within the base 11, while the massage protrusions 145 retract into or extend out of the base 11 to massage the user's legs.

[0035] The height and / or width of the multiple massage bumps 145 can be different, so that during the rotation of the massage head, massage bumps 145 of different sizes will extend from the base 11 and press on the user's legs, thus providing the user with a richer massage experience. At the end of the massage, the massage head can be stored by simply controlling the massage bumps 145 to retract into the base 11.

[0036] Optionally, the guide groove 151 is straight and is inclined relative to the first surface 111 of the base 11, and the scraper 141 extends from the first surface 111 out of the base 11.

[0037] The guide groove 151 extends in a straight line, so that the scraper 141 also slides back and forth in a straight line under the constraint of the guide groove 151. The base 11 has a first surface 111, on which a first through hole 112 and a second through hole 113 are provided. The first through hole 112 is used for the massage head to retract into and extend out of the base 11, and the second through hole 113 is used for the scraper 141 to retract into and extend out of the base 11. The guide groove 151 is not parallel to the first surface 111, so that the degree to which the scraper 141 extends out of the base 11 will vary during the movement of the scraper 141, thus providing the user with a massage experience of different intensities.

[0038] Optionally, the scraper 141, driven by the drive assembly and constrained by the guide groove 151, has an initial position and a maximum extension position, and the scraper 141 reciprocates between the initial position and the maximum extension position. The first end 1511 of the guide groove 151 is closer to the initial position, and the opposite second end 1512 is closer to the maximum extension position. The first end 1511 is further away from the first surface 111 than the second end 1512. Thus, as the scraper 141 approaches the maximum extension position, its extension becomes increasingly greater, allowing for better contact with the user's legs and providing massage with varying intensities. When the scraper 141 returns to the initial position, it can be retracted into the base 11 for storage.

[0039] To facilitate the retraction of the massage head and scraper 141 after the massage, the base 11 may optionally include a position sensor 16 and a control component. The control component is electrically connected to the position sensor 16 and the drive component, respectively. The position sensor 16 detects the position information of the massage head and / or scraper 141 and sends this information to the control component. The control component then controls the drive component to retract the massage head and scraper 141 into the base 11 based on the position information. After retraction, neither the massage head nor the scraper 141 protrudes from the surface of the base 11.

[0040] Furthermore, the massage head and / or scraper 141 are provided with magnets, and the position sensor 16 obtains the position information of the massage head and / or scraper 141 by sensing the magnets.

[0041] To facilitate the installation of the various structures within the base 11, optionally, please refer to... Figure 2 The base 11 includes a base 114 and an upper cover 115 that engages with the base 114. The drive assembly, main drive shaft 13, and massage assembly are all housed within the base 11. In use, the upper cover 115 faces the user's legs. The upper cover 115 has a first through hole 112 and a second through hole 113. The massage head of the massage assembly extends from the first through hole 112, and the scraper 141 extends from the second through hole 113 to massage the user's legs.

[0042] Optionally, the base 11 also includes a scraper guide seat 116 disposed on the base 114, a guide groove 151 disposed on the scraper guide seat 116, and a guide post 152 disposed on the scraper 141. Disposing of the guide groove 151 on the scraper guide seat 116 facilitates the machining of the guide groove 151.

[0043] Optionally, please refer to the following: Figure 4 The base 11 also includes a first fixed seat 117 disposed on the base 114, and the two ends of the drive shaft are respectively rotatably disposed on the first fixed seat 117.

[0044] Alternatively, please refer to Figure 2 and Figure 3 The massage assembly also includes an eccentric shaft 146, one end of which is eccentrically connected to the massage head and the other end is rotatably disposed in the base 11. The scraper 141 is rotatably disposed on the eccentric shaft 146.

[0045] The scraper 141 is connected to the massage head via an eccentric shaft 146. The axis of the eccentric shaft 146 is parallel to the axis of the massage head. One end of the eccentric shaft 146 is fixedly connected to the massage head, while the other end is rotatably mounted within the base 11 for easy rotation. The scraper 141 is fitted onto the eccentric shaft 146 and can rotate relative to it. Connecting the scraper 141 to the massage head using the eccentric shaft 146 results in a simple and easily implemented structure.

[0046] Optionally, the scraper 141 includes a scraper body 1411 and a curved arm 1412. The scraper body 1411 is used for massage, and one end of the curved arm 1412 is fixedly connected to the scraper body 1411, while the other end is eccentrically and rotatably connected to the massage head.

[0047] The extension direction of the curved arm 1412 is parallel or nearly parallel to the length direction of the user's leg. The extension of the curved arm 1412 allows the scraping plate body 1411 and the massage head to be positioned differently, thus saving space in the width direction and allowing for separate massage of different areas of the leg in the length direction. Multiple scraping bumps 1413 can be provided on the side of the scraping plate body 1411 facing the user's leg to provide a scraping experience.

[0048] Optionally, the massage head includes a first massage head 142 and a second massage head 143. The first massage head 142 is fixed on the main drive shaft 13, and the second massage head 143 is eccentrically and fixedly connected to the first massage head 142. The scraper 141 is located between the first massage head 142 and the second massage head 143.

[0049] The first massage head 142 and the second massage head 143 can be two different sizes of massage heads. When used together, they can provide users with a richer massage experience. Placing the scraping tool 141 between the first massage head 142 and the second massage head 143 makes it easier to align the scraping tool 141 with the middle area of ​​the leg, thereby enhancing the scraping experience.

[0050] Furthermore, please refer to Figure 2 and Figure 4 The second massage head 143 has a mounting shaft 17 on its side away from the first massage head 142. The mounting shaft 17 coincides with the axis of the main drive shaft 13. The base 11 also includes a second fixed seat 118 disposed on the base 114. The mounting shaft 17 is rotatably disposed in the second fixed seat 118.

[0051] Optionally, the drive assembly includes a motor 121, a first bevel gear 122, and a second bevel gear 123. The output shaft of the motor 121 is coaxially connected to the first bevel gear 122, and the main drive shaft 13 is coaxially connected to the second bevel gear 123. The first bevel gear 122 meshes with the second bevel gear 123, and the output shaft of the motor 121 is perpendicular to the main drive shaft 13.

[0052] The output shaft of motor 121 drives the main drive shaft 13 to rotate around its own axis via the first bevel gear 122 and the second bevel gear 123, thereby achieving synchronous drive of the two massage components. The first bevel gear 122 and the second bevel gear 123 cooperate to change the direction of motion transmission, thereby utilizing the space between the two massage components and reducing the size of the massage leg rest 10 in the width direction.

[0053] Optionally, there are two main drive shafts 13, which are coaxially arranged, and the massage heads of the two massage components are respectively fixed on the two main drive shafts 13. The drive assembly includes a motor 121, a first bevel gear 122, and two second bevel gears 123. The output shaft of the motor 121 is coaxially connected to the first bevel gear 122. One main drive shaft 13 is coaxially connected to one second bevel gear 123, and the other main drive shaft 13 is coaxially connected to the other second bevel gear 123. The first bevel gear 122 meshes with the two second bevel gears 123 respectively, and the output shaft of the motor 121 is perpendicular to the main drive shafts 13.

[0054] The output shaft of motor 121 drives two main drive shafts 13 to rotate around their own axes via a first bevel gear 122 and two second bevel gears 123, thereby achieving synchronous drive of the two massage components. The first bevel gear 122 and the two second bevel gears 123 cooperate to change the direction of motion transmission, thereby utilizing the space between the two massage components and reducing the size of the massage leg rest 10 in the width direction.

[0055] Optionally, the base 11 also includes a motor mount 119 disposed on the base 114, and the motor 121 is fixed on the motor mount 119.
