Detailed implementation manners

[0019] An embodiment of the present invention provides a lower limb massage device for massaging a user's legs, including a main control board, a bracket 1, and a leg massage component 2 provided on the bracket 1. The bracket 1 is provided with a receiving groove 3 for receiving the legs, and the receiving groove 3 is arranged towards the rear side of the user's legs. The leg massage component 2 includes a connecting portion 4, a driving portion 5, a massage head 6, a position detector, and a contact sensor. The connecting portion 4 is provided on the bracket, and the connecting portion 4 is arranged close to the left side or the right side or the front side of the user's legs. The massage head 6 is arranged on the connecting portion 4. The driving portion 5 can push the massage head 6 to move away from the connecting portion 4 so as to contact the user's legs. The position detector is used to detect the real-time position of the massage head when it is pushed by the driving portion. The contact sensor is arranged on the massage head 6 for detecting whether the massage head 6 contacts the legs and transmitting the detection result to the main control board. The main control board is data-connected to the position detector. Refer to Figure 8 and Figure 9 , the leg circumferences of different users are different. In order to enable the lower limb massage device to adapt to the leg circumference of the user for massage, the lower limb massage device is provided with a driving portion 5, a massage head 6, and a connecting portion 4. The driving portion 5 can push the massage head 6 to move away from or close to the connecting portion 4 so as to contact the user's legs, and then enable the massage head 6 to stay at a suitable position to massage the user's legs. On the premise of knowing the leg circumference of the user, the main control board can comprehensively judge the position of the massage head 6 based on the information of the position detector and the contact sensor to more accurately control the massage head 6 to massage the user's legs. In the embodiment of the present invention, after the main control board obtains the data of the leg circumference, it will control the massage head 6 to move a preset distance relative to the connecting portion 4. When the position detector monitors that the distance of the massage head 6 moving relative to the connecting portion 4 reaches the preset distance, and the pressure monitored by the contact sensor also reaches a certain threshold, it is determined that the massage head 6 has moved to a suitable position, and the main control board will control the massage head 6 to stop moving.

[0020] Refer to Figure 6, the lower body massage device further includes a traveling mechanism 7 and a frame 8. The traveling mechanism 7 is disposed on the frame 8, and the leg massage component 2 is connected to the traveling mechanism 7. The traveling mechanism 7 can drive the leg massage component 2 to reciprocate in a direction parallel to the leg. Since the leg massage component 2 is connected to the traveling structure 7, the traveling mechanism 7 can drive the leg massage component 2 to reciprocate in a direction parallel to the leg. In an embodiment of the present invention, the leg massage component 2 is disposed on the bracket 1, and the bracket 1 is directly connected to the traveling mechanism 7. Therefore, the traveling mechanism 7 drives the bracket 1 to reciprocate in a direction parallel to the leg. Thus, the leg massage component 2 can massage more positions of the user's leg along the user's leg, bringing a better massage experience to the user.

[0021] The traveling mechanism 7 includes a driving lead screw 9. One end of the driving lead screw 9 is connected to the bracket 1, and the other end of the driving lead screw 9 is connected to the frame 8 and is used to drive the bracket 1 to reciprocate. When the driving lead screw 9 rotates, since the bracket 1 is sleeved on the driving lead screw 9, the bracket 1 will also move up and down as the driving lead screw 9 rotates, thereby causing the leg massage component 2 to reciprocate in a direction parallel to the leg.

[0022] Reference Figure 7 , a slide rail 10 is provided on the frame 8, and a slider 11 is provided on the bracket 1. When the bracket 1 reciprocates, the slider 11 is received in the slide rail 10. Therefore, the driving lead screw 9 can drive the bracket 1 to move along the frame 8, and due to the cooperation of the slide rail 10 and the slider 11, the up and down movement of the bracket is more stable and is not prone to skew.

[0023] In an embodiment of the present invention, reference Figure 6 , further includes a traveling detector 12. The traveling detector 12 is used to detect the position of the movement of the traveling mechanism 7 in real time and feed the detection result back to the main control board. Further, the traveling detector 12 includes a motor speed code disk 121 and a motor speed sensor 122. The motor speed code disk 121 and the motor speed sensor 122 cooperate with each other to measure the rotation speed of the driving lead screw 9. When the bracket 1 reciprocates along the frame 8, when the massage head 6 reaches a position where the leg is thicker, due to the increased resistance, the massage head 6 will decelerate, and then the driving lead screw 9 will also reduce the rotation speed. Conversely, when the massage head 6 reaches a position where the leg is thicker, due to the increased resistance, the massage head 6 will decelerate, and then the driving lead screw 9 will also reduce the rotation speed. After the traveling detector detects that the speed of the driving lead screw 9 decreases, it feeds this information back to the main control board, and the main control board will then know the position where the massage head 6 is currently located.

[0024] In an embodiment of the present invention, reference Figure 8 andFigure 9 The driving part includes a driving motor 13 and a push rod 14. The driving motor 13 drives the push rod 14 to move. The push rod 14 is connected to the massage head 6. The position detector determines the position of the massage head 6 by detecting the rotation of the driving motor 13. The position detector determines the position of the massage head 6 by detecting the rotation speed and / or the number of rotations of the driving motor. In another embodiment, the position detector can also determine the position of the massage head 6 by detecting the distance that the push rod 14 moves forward or backward. Similarly, the driving motor 13 can also be a device that can provide power, such as a cylinder.

[0025] The driving part further includes a connecting rod 15, one end of the massage head 6 is hinged on the connecting part 4, one end of the connecting rod 15 is hinged to the push rod 14, and the other end of the connecting rod 15 is hinged to the massage head 6. When the driving motor 13 pushes the push rod 14 to reciprocate, the connecting rod 15 pushes the massage head 6 to rotate relative to the connecting part 4. The massage head 6 is arranged on a side of the connecting part 4 close to the user's legs, and one end of the massage head 6 is hinged to the connecting part 4. The driving part is fixedly arranged on a side of the connecting part 4 away from the user's legs, one end of the connecting rod 15 is hinged to the push rod 14, and the other end is hinged to the other end of the massage head 6, so when the driving motor 13 pushes the connecting rod 15 to move, the connecting rod 15 can push the massage head 6 to deflect relative to the connecting part 4. In another embodiment, the driving part includes an airbag, an air pump and an air valve. The airbag is arranged between the massage head 6 and the connecting part 4. The air valve controls the air pump to inflate and deflate the airbag to expand or contract the airbag, thereby causing the massage head 6 to deflect relative to the connecting part 4.

[0026] refer to Figure 5In the embodiment of the present invention, a leg length detector is also included. The leg length detector includes a tripod 16, a foot sensor 17, a second drive motor 18, and a position sensor 19. The tripod 16 is reciprocatingly connected to the frame 8. The second drive motor 18 is used to drive the tripod 16 to reciprocate relative to the frame 8. The foot sensor 17 is arranged on the tripod 16 corresponding to the sole of the user's foot. When the tripod 16 moves toward the user's foot and the sole of the foot contacts the foot sensor 17, the leg length detector transmits the position information of the foot detected by the position sensor 19 at the time of contact to the main control board. Specifically, the position sensor 19 includes a telescopic counting box 191 and a telescopic counting code disk 192. The telescopic counting box 191 is fixed on the frame 8. The telescopic code disk 192 is provided with a counting bar 193. The counting bar 193 is provided with a counting hole. The counting bar 193 passes through the telescopic counting box 191. When the sole of the user's foot contacts the foot sensor 17 , it is calculated which counting hole is covered by the telescopic counting box 191 , and then the distance the foot stand 16 moves upward relative to the frame 8 is calculated.

[0027] The main control board obtains the distance that the footrest 16 moves relative to the frame 8 based on the position information of the foot and compares it with the database, thereby calculating the leg length of the user, and then calculating the massage stroke that the bracket 1 can move along the frame 8. For users with different leg lengths, the position of the calf is also different. Therefore, in order to prevent the leg massage component 2 from rolling to the user's kneecap and giving the user a bad massage experience, the main control board will reasonably determine the massage stroke that the bracket 1 can move along the frame 8 based on the calculated leg length of the user.

[0028] refer to Figure 6 The upper and lower ends of the frame 8 are respectively provided with an upper travel sensor 20 and a lower travel sensor 21, and the bracket 1 is provided with a sensing member 22, which cooperates with the upper travel sensor 20 and the lower travel sensor 21 to determine the massage stroke of the bracket 1 that can move along the frame 8. Preferably, the sensing member 22 is an induction magnet, which is provided on the side of the bracket 1 away from the user's legs, and the sensing member 22 can move with the movement of the bracket 1.

[0029] The main control board combines the data of the walking detector 12, the contact sensor, the position detector, and the position sensor 19 to determine the dimensions of different positions of the user's leg. The main control board further includes a massage technique generation module, and the generation module generates corresponding massage programs according to the dimensions of different positions of the user's leg. The main control board will pre-obtain data such as the leg circumference and length of the user's leg according to the data of the walking detector 12, the contact sensor, the position detector, and the position sensor 19, and reasonably formulate corresponding massage programs for massage according to these data.

[0030] During massage, the process from the massage head contacting the leg to applying the maximum massage force forms a massage cycle. The generation module formulates the maximum massage force in each massage cycle according to the dimensions of different positions of the leg to ensure that the maximum massage force in each massage cycle meets the preset value. The maximum massage force can be judged according to the moving distance of the massage head 6 detected by the position detector and the pressure value detected by the contact sensor.

[0031] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application is also intended to include these changes and modifications.
