Detailed Description

In the following description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the device or element being referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model, and it is obvious that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

A human body mechanical soft and hard sole is shown in figure 1, and comprises a body 1, wherein a heel part 2, an arch part 3 and a sole part 4 are arranged on the body 1, the body 1 is formed by PU material through hot press, a hot-pressed mold can form empty slots with corresponding shapes at the heel part 2, the arch part 3, the sole part 4 and the like, after the body 1 is cooled and formed, TPU and EVA hot-press forming materials with different hardness are sequentially adopted to hot-press the empty slots corresponding to the body 1, so that a complete sole is obtained after cooling, the hardness of the heel part 2, the arch part 3 and the sole part 4 on the sole is different, and the feedback of each part is different in the process of treading and pressing by a wearer.

As shown in fig. 1, in the sole according to the present utility model, the hardness of the heel 2 is the greatest, the specific hardness is the shore D80±2 degree, the shore D80±2 degree is the greater hardness, and the heel 2 is selected to be the hardness, because in the process of walking by the wearer, when the wearer steps on, the position of the center of gravity is located behind the foot, the pressure and load born by the heel are the greatest at this time, so that the greater hardness is selected, the pressure and load can be better released and transferred, and because the heel lands first, the greater hardness can also enable the wearer to land more smoothly, the stepping sense during the landing is greater, so that the sole is more comfortable, accords with the human body mechanics, and the heel 2 adopts the hot press molding, the hardness range of the TPU material is wide, the hardness is the greater, the elasticity of the TPU cannot deform due to the increase of the hardness, the TPU still maintains good elasticity and flexibility at-35 ℃, and the impact resistance, the bearing capacity, the cold resistance and the shock absorbing performance are very suitable for manufacturing the sole.

As shown in FIG. 1, the hardness of the arch part 3 is minimum, the specific hardness is Shore D40+/-2 degrees, the hardness of Shore D40+/-2 degrees is low, the feeling is softer and the elasticity is realized, the arch part is pressed and loaded after the whole foot is pressed and flatly, the gravity center position is moved forward, the pressure born by the arch part is minimum under the support of the heel and the sole, the arch consists of muscles and does not have bones, so the hardness of the foot softness is selected, on one hand, the pressure and the load born by the arch can be better adapted, on the other hand, the better protection of the arch can be further provided, the fatigue of the muscles is reduced, and the arch part 3 is further provided with the bulge 7 attached to the arch, so after the foot is pressed flatly, the arch part can be better supported, the pressure of the foot is better dispersed, the comfort is further increased, the fatigue of the muscles is reduced, the arch part 3 and the sole part 4 are both made of EVA, the characteristics of light material, high wear resistance, strong impact resistance and the like are provided, and the comfort of the wearer is improved, and the other performances of the sole can be improved at the same time.

As shown in fig. 1, the hardness of the sole portion 4 is greater than that of the arch portion 3, but less than that of the heel portion 2, the hardness of shore D60±2 is adopted, the shore D60±2 is a hardness which is medium in hardness, and the sole portion has a certain elasticity, but also has a better supporting effect, because the sole is supported independently, the wearer has stepped on one step again and then begins to lift the foot, at this time, for the rear foot, the center of gravity moves forward to the front of the foot again, the pressure and load borne by the sole are increased, but the center of gravity position is different, so the pressure and load borne by the sole are not as great as when the heel is supported independently, the hardness of shore D60 is the most suitable, and because the three parts are laid flat, the pressure and load borne by the sole are different, the heel and the sole have a skeleton structure, and have a greater supporting effect, the pressure and load are also larger than the sole, and the heel is directly connected with the ankle, so the pressure of the weight of the body can be directly conducted to the place, the pressure borne by the sole is greater than the sole, the pressure and the heel is directly connected with the ankle, and the heel is more comfortable to the wearer, and the pressure can be released to the wearer and feel more comfortable to the human body.

As shown in fig. 1, the body 1 is provided with a foot protection part 5, which is specifically a baffle 6 bonded around the heel part 2, and the rigidity of the baffle 6 is the same as that of the heel part 2, so that the rigidity of the baffle 6 is also larger, and meanwhile, the baffle 6 also wraps the side surface of the heel, so that the baffle 6 is matched with the heel part 2, and then the heel is wrapped, thereby limiting the twisting amplitude of the wearer to two sides when the wearer walks or stands, increasing the resistance when the wearer twists when the wearer steps on the ground, and making the wearer's foot difficult to twist to two sides due to the resistance of the baffle 6, so that the probability of twisting the foot can be reduced to a certain extent.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
