Along the circumference of the wavy non-rotating structure, the depth of the groove is different on different axial sections, and it gradually decreases as the distance between the crest structure 2 and the trough structure 3 and the bottom surface 4 decreases.

[0064] See also Figure 3 , Figure 3 A schematic cross-sectional view of a wave crest structure of an integrated soft power-assisting device provided in an embodiment of the present application. The cross-sectional structure of the wave crest structure 2 and the corresponding bottom surface 4 connected thereto in the radial direction includes but is not limited to a first arc 21 and a first bottom edge line 22.

The second arc 31 includes a parabola, a quadratic curve, a fitting line, etc.

[0066] like Figure 1 , Figure 2 As shown, the width of the crest structure 2 in the circumferential direction increases successively along the circumferential direction of the crest or remains consistent along the circumferential direction of the crest. The minimum cross-sectional area of ​​the cavity of the trough structure 3 in the radial direction is greater than the maximum cross-sectional area of ​​the cavity of the crest structure 2 in the radial direction. times, and in the axial middle section, the cavity height corresponding to the trough structure 3 is greater than the cavity height corresponding to the peak structure 2. times, and at the same time, in the wavy non-rotating body structure, the minimum cross-sectional area of ​​the cavity of the trough structure in the radial direction should be smaller than the maximum cross-sectional area of ​​the cavity of the peak structure in the radial direction, and the cavity height corresponding to the trough structure should be smaller than the cavity height corresponding to the peak structure. For example, the cavity height corresponding to the trough structure 3 is times the cavity height corresponding to the peak structure 2. times or times.

[0067] like Figure 1 , Figure 2 As shown, the width of the peak structure 2 in the axial direction of the power-assisting device can be gradually increased along the axial direction of the peak, which helps to increase the overall deformation of the entire integrated soft power-assisting device and reduce stress, and can also keep the width of the peak structure 2 consistent along the axial direction of the peak.

[0068] like Figure 1 As shown, the entire integrated soft power assist device is an integrated structure, and the entire integrated soft power assist device can be an integrated axial up-and-down asymmetric structure or a left-right symmetrical structure. The material of the entire integrated soft power assist device can be, but is not limited to, elastic material, and can also be made of other materials, and can be set according to specific needs and application scenarios. The integrated soft power assist device can be adjusted according to the length requirements of the limb joints, increasing the versatility of the device.

[0069] like Figure 2 As shown, in order to make the surface stress distribution of the cavity structure 8 of the entire integrated soft booster device more uniform, the top of the axial cross section of the crest structure 2 can be a circular arc, and the top of the axial cross section of the trough structure 3 can be a groove-shaped circular arc, and the radius of the circular arc at the top of the crest structure 2 can be the same as or different from the size of the groove-shaped circular arc at the top of the trough structure 3. The air intake pipe 1 at one end of the integrated soft booster device is closed, and the air intake pipe 1 at the other end is connected, or both ends are connected, so the integrated soft booster device of different lengths can be connected according to needs.

[0070] like Figure 3 , Figure 4 As shown, the inner side of the crest structure 2 and the trough structure 3 is a cavity, and the outer side is a corrugated surface. In order to provide a larger curvature and a more uniform stress distribution, the specific design adopted is: the overall cross-sectional profile of the crest structure 2 is composed of an upper arc line 21 and a first bottom edge line 22, and the overall cross-sectional profile of the trough structure 3 is composed of multiple segments of second arc lines 31, and the lower arc line of the trough profile is tangent to the second bottom edge line 32.

[0071] like Figure 1As shown, the present invention also provides a limb power-assisting trainer, which includes the above-mentioned integrated software power-assisting device, which is used to train limbs, and the entire integrated software power-assisting device is sleeved on the surface of the limbs, which can train human limbs, effectively train human joints, and make human limbs more flexible.

[0072] like Figure 1 , Figure 2 As shown, in order to further understand the technical solution of the integrated soft power-assisting device of the present invention, the present invention also provides the working process of the integrated soft power-assisting device. During the working process, the integrated soft power-assisting device: first, inflate and inhale through the air intake pipe 1. During the inflation and inhalation, the deformation of the integrated soft power-assisting device is mainly deformed by the change of the angle of the adjacent angles of the wave crest structure 2. When the integrated soft power-assisting device is inflated, the angle of the adjacent angle of the wave crest structure 2 will become larger and open to both sides, so that the top surface of the wavy non-rotating body structure 7 is deformed to a large extent, deformed as a whole, and bends toward the bottom surface 4, which can make the limbs in a bent state. When the limbs need to be stretched, the integrated soft power-assisting device can be inhaled, and the air intake pipe 1 is inhaled. The angle of the adjacent angle of the wave crest structure 2 will decrease and shrink toward the middle of the wave crest structure 2, so that the integrated soft power-assisting device can bend toward the top surface of the wavy non-rotating body structure 7, which can produce a limb extension state. When the patient's limbs are in a state of being unable to stretch, the integral soft power-assisting device can continue to be inhaled, so that the cavity structure 8 further forms a larger negative pressure, which promotes the patient's limbs to fully unfold and perform slight over-stretching exercises.

[0073] like Figure 1 , Figure 2 As shown, the integrated software power-assisting device can also perform autonomous training. Autonomous training is when the strength of the limbs is good and can be bent and stretched autonomously. The integrated software power-assisting device can buffer and protect the force when the limbs are bent to avoid limb injuries caused by excessive exercise. Non-autonomous training is when the patient's limbs are completely powerless. The integrated software power-assisting device can set the air pressure to perform quantitative training on the patient, so that the patient can perform appropriate exercise with the help of the software power-assisting device. It can also inhale through the air inlet pipe 1 to stretch the patient's limbs when the patient is unable to stretch.

[0074] In summary, the integrated soft power-assisting device of the present invention includes a power-assisting device, an air intake pipe 1, and a fixing device 6. The present invention adopts an integrated molding structure, which is simple in structure and can be adjusted according to different limb joints of the human body to meet the needs of different parts of different people. The present invention has a simple structure and can be integrally molded to reduce the production cost. The internal pressure distribution is uniform and better matches the limb joint activity, thereby improving the power-assisting efficiency between the limb joints.

[0075] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
