[0059] Example 3
[0060] See Figures 9-13 The present invention provides a muscle relaxation device according to embodiment 3, comprising the outer shell assembly described in embodiment 1 or embodiment 2, a first wheel group 5 and a second wheel group 6 disposed at both ends of the outer shell assembly, and a drive mechanism 7 disposed inside the outer shell assembly. The drive mechanism 7 drives the first wheel group 5 and the second wheel group 6 to rotate. When the outer shell assembly is under load, the automatic rolling and pressing of muscles is completed under the cooperation of the load rotation of the outer shell assembly and the rotation of the first wheel group 5 and the second wheel group 6.
[0061] By applying the housing assembly described in Example 1 to a muscle relaxation device, not only is it possible to freely select different protrusion structures according to the user's body shape, but it also improves the comfort and experience of different users, while enhancing the product quality of the housing assembly and its competitiveness in muscle relaxation devices.
[0062] Specifically, the power module inside the outer casing assembly provides power to the drive mechanism 7, which in turn drives the first wheel group 5 and the second wheel group 6 at both ends of the outer casing assembly to roll. This not only allows users to achieve deep relaxation of most of their muscles in both lying and prone positions, saving time and effort, and enabling them to rest or use their mobile phones during the relaxation process, but also makes full use of the internal space of the outer casing assembly, resulting in a small overall size and easy portability, without requiring an external power supply. Alternatively, an external power cord can be used to power the drive mechanism 7.
[0063] In this embodiment, a bearing 8 is provided on the inner wall of the fixing member 3 in the outer shell assembly, and the outer shell assembly is connected to the drive mechanism 7 through the bearing 6.
[0064] Specifically, such as Figure 10 As shown, when the outer casing assembly is under load, it is connected to the drive mechanism 7 via the bearing 8. The outer casing assembly rotates under force, and the drive mechanism 7 rotates accordingly, driving the first wheel group 5 and the second wheel group 6 to roll. Even when the power module cannot provide power, the drive mechanism 7 can still rotate under force through the outer casing assembly when the user uses the muscle relaxation device with synchronized automatic rolling motion on both sides, and the muscle relaxation device can also roll accordingly.
[0065] This allows users to achieve deep relaxation of most muscles in their body in a "lying down" or "prone" position, saving time and effort.
[0066] In the specific implementation process of this embodiment, the drive mechanism 7 includes a reducer 71, a connector 72 and a drive motor 73. The reducer 71 is connected to the output shaft of the drive motor 73, the drive motor 73 is located in the connector 72, and the first wheel set 5 and the bearing 8 are both connected to the reducer 71.
[0067] In this embodiment, the drive mechanism 7 further includes a connecting pipe 74 for connecting the first wheel set 5 and the second wheel set 6.
[0068] In this embodiment, one end of the connecting pipe 74 is connected to one end of the connecting member 72, the other end of the connecting pipe 74 is connected to the second wheel group 6, and the other end of the connecting member 72 is connected to the speed reducer 71.
[0069] Specifically, such as Figure 10As shown, the drive motor 73 is located inside the connector 72. The drive motor 73 runs its output shaft to drive the reducer 71 to rotate, and the first wheel set 2 rolls accordingly. The reducer 71 drives the connector 72 to rotate with the connecting pipe 74. The connecting pipe 74 transmits power to the second wheel set 6, and the second wheel set 6 rotates at the same speed and torque.
[0070] In addition, the bearing 8 is located around the periphery of the reducer 71. When the reducer 71 rotates, the outer casing assembly rotates in the opposite direction. The first wheel group 5 and the second wheel group 6 at both ends of the outer casing assembly are mechanically synchronized through the connector 72 and the connecting pipe 74, realizing the power synchronization of the first wheel group 5 and the second wheel group 6 on both sides of the muscle relaxation rolling device. This simplifies the control difficulty, improves the stability of the product, and reduces the cost of the control part due to the simplification of control.
[0071] In this embodiment, the speed reducer 71 includes a planetary gear carrier 711, a sun gear 712, planetary gears 713, and an external gear ring 714. The sun gear 712 and planetary gears 713 mesh with each other and are mounted on the planetary gear carrier 711. The external gear ring 714 meshes with the planetary gears 713 and is connected to the outer housing assembly. The sun gear 712 is connected to the output shaft of the drive motor 73, and the planetary gear carrier 711 is connected to the connecting member 72.
[0072] Specifically, such as Figure 11 As shown, when the external gear ring 714 is unloaded, the output shaft of the drive motor 73 transmits power to the sun gear 712. The sun gear 712 rotates and the planet gear 713 rotates in the opposite direction. The external gear ring 714 and the sun gear 712 rotate in the same direction, and the first gear set 5 and the second gear set 6 remain stationary. When the external gear ring 714 is under load, the user lies or sits on the outer shell assembly, and the external gear ring 714 rotates. At this time, the drive motor 73 continues to output power, and the planet gear carrier 711 and the sun gear 712 rotate in the same direction. The planet gear carrier 711 transmits power to the connector 72 and the connecting pipe 74, and the connecting pipe 74 drives the second gear set 6 to rotate.
[0073] In this embodiment, the first wheel set 5 includes a support member 51 and a first synchronous wheel set 52 disposed on the support member 51, and the planetary gear carrier 711 is connected to the first synchronous wheel set 52.
[0074] In this embodiment, the second wheel group 6 includes a support member 61 and a second synchronous wheel group 62 disposed on the support member 61, and the other end of the connecting pipe 74 is connected to the second synchronous wheel group 62.
[0075] Specifically, this implementation example Figure 9 , Figure 12 and Figure 13As shown, both the first gear group 5 and the second gear group 6 are triangular. The first synchronous gear group 52 includes three synchronous gears located at the three corners of the triangular first gear group 5. The planetary gear carrier 711 is connected to one of the synchronous gears, driving the first gear group 5 to rotate. The second synchronous gear group 62 also includes three synchronous gears located at the three corners of the triangular second gear group 6. The other end of the connecting pipe 74 is connected to one of the synchronous gears, driving the second gear group 6 to rotate. The design of the support component prevents the first gear group from contacting the ground.
[0076] In addition, the number of synchronization wheels in the first group 5 and the second group 6 is at least 3.
[0077] In the specific implementation process of this embodiment, the first wheel group 5 and the second wheel group 6 also include tracks, and the two tracks are respectively fitted onto the first synchronous wheel group 51 and the second synchronous wheel group 62.
[0078] Specifically, such as Figure 5 As shown, the first wheel group 5 and the second wheel group 6 are fitted with tracks to protect the support member 51, the first synchronous wheel group 51 and the second synchronous wheel group 62, thereby increasing their service life.
[0079] In this embodiment, the relaxation device also includes a sensor and two drive mechanisms 7, with the sensor electrically connected to the two drive mechanisms 7.
[0080] In this embodiment, one drive mechanism 7 is connected to the first wheel group 5, and the other drive mechanism 7 is connected to the second wheel group 6.
[0081] Specifically, two drive mechanisms 7 are respectively located at both ends of the housing assembly. One drive mechanism 7 is connected to the first wheel group 5, and the other drive mechanism 7 is connected to the second wheel group 6. The two drive mechanisms 7 are connected by a sensor to control the two drive mechanisms 7 to rotate synchronously.
[0082] The working principle of the bilateral power-synchronized automatic muscle-relaxing device provided in this embodiment is as follows: When the user is not using the device, the outer casing assembly is unloaded, i.e., the outer gear ring 714 is unloaded. The output shaft of the drive motor 73 transmits the power source to the sun gear 712. The sun gear 712 rotates, and the planetary gear 713 rotates in the opposite direction. The outer gear ring 714 and the sun gear 712 rotate in the same direction, and the first gear group 5 and the second gear group 6 remain stationary. When the user uses the bilateral power-synchronized automatic muscle-relaxing device in the "lying down" and "prone" positions, the user... The foam roller rests on the outer casing assembly, and is loaded via the external gear ring 714 connected by the bearing 8. The external gear ring 714 rotates, driving the motor 73 to continue outputting power. The planetary gear carrier 711 and the sun gear 712 rotate in the same direction. The planetary gear carrier 711 transmits power to the connector 72 and the connecting pipe 74. The connecting pipe 74 drives the second wheel set 6 to rotate, achieving deep relaxation of most muscles in the body in a time-saving and labor-saving manner. During the relaxation process, one can rest or use a mobile phone. Moreover, the internal space of the foam roller body of this utility model is fully utilized, and the overall size is small and easy to carry, without the need for an external power supply.
[0083] Furthermore, this invention can still achieve the purpose of rolling and massaging the user's muscles even when the power module is out of power. In the two positions of "lying down" and "lying down", the foam roller body 1 is rotated by the external force, and the drive mechanism 7 is connected to the outer shell assembly through the bearing 8. When the outer shell assembly is rotated by the force, the drive mechanism 7 also rotates accordingly. The drive mechanism 7 drives the first roller group 5 and the first roller group 6 to roll forward through the synchronization of the mechanical structure, thereby completing the deep relaxation of the muscles.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
