Referring to fig. 1 and 2, the present embodiment discloses an ultrahigh-elasticity cushioning structure, which is applied to a sole, and includes a plurality of cushioning elements 1 formed in a front sole region and/or a rear sole region of the sole, where the cushioning elements 1 are made of an elastic material, in the present embodiment, the cushioning elements 1 are made of an EVA material, a longitudinal cross section of each cushioning element 1 is of an omega-like symmetric structure, and the cushioning elements 1 include a connecting portion 11, a shaping portion 12, a bending portion 13, and a supporting portion 14. Connecting portion 11 that is located the top transversely sets up, and the longitudinal cross section of connecting portion 11 is the pitch arc structure of upwards uplift, and the thickness at both ends is greater than the thickness at its middle part about it, and connecting portion 11 top is connected fixedly with the sole, mainly plays the effect of connecting, deformation buffering, bradyseism, energy storage, when receiving the effort of equidimension not, and connecting portion 11 can the corresponding crooked deformation that takes place the not co-occurrence degree, because its self elasticity characteristic afterwards, can in time reset, resume to original state.

Moulding portion 12 of both ends bottom fixedly connected with about connecting portion 11, the moulding portion 12 of the left and right sides is the circular-arc structure of symmetry, constitutes bracket-like form jointly, and is concrete, and its vertical middle part thickness diminishes towards both ends from top to bottom gradually, and the thickness of moulding portion 12 is greater than the thickness of connecting portion 11, mainly plays and connects below connecting portion 11 and the portion of bending 13, and when connecting portion 11 and the portion of bending 13 take place to be out of shape, the moulding portion 12 of both sides can play and keep framework form position, avoids the effect that the structure collapsed.

The bottom of the shaping portion 12 is connected with a bending portion 13, and the main functions of the bending portion 13 are connection, deformation buffering, cushioning and supporting. The portion 13 of bending of the left and right sides is the symmetrical structure of all inwards buckling, the thickness of the portion 13 of bending is less than the thickness of the shaping portion 12, the outside turning of the portion 13 of bending is the acute angle, this makes when receiving longitudinal force, the portion 13 of bending of the left and right sides can take place to buckle, both ends draw close each other from top to bottom, outside turning angle diminishes, inboard turning tip is to well removal, when the effort that receives is enough big, the inboard turning tip of the portion 13 of bending of both sides removes to central point and puts the offset contact, form the structure of mutual support.

The bottom of the bending part 13 is connected with a supporting part 14, the supporting parts 14 on the left side and the right side are all arranged in an outward inclined mode, the thickness of the supporting part 14 gradually increases from top to bottom, the bottom of the supporting part is fixedly connected with the sole, and the supporting and bearing effects are mainly achieved.

It should be noted that the elastic strength of the connecting portion 11 and the bending portion 13 is less than the elastic strength of the shaping portion 12 and the supporting portion 14, which helps the connecting portion 11 and the bending portion 13 to act as a flexible combination to respond faster and more timely and to perform a deformation reaction when an acting force is applied, and the shaping portion 12 and the supporting portion 14 act as a rigid combination to serve as a connecting structure, a holding structure and a bearing in the process.

In the specific implementation process, with reference to fig. 9 to 11, when a small longitudinal acting force is applied, as shown in fig. 9, the cushioning performance of the cushioning element 1 is mainly reflected in the first deformation region 10, the connecting portion 11 is first slightly deformed, the bending radian of the connecting portion is reduced, the deformation degree is matched with the applied force, the applied force can be buffered and absorbed, and the cushioning effect is achieved, and the shaping portion 12, the bending portion 13 and the supporting portion 14 are kept still, which is helpful for keeping the stability of the overall structure of the cushioning element 1, so that the sole of a wearer can keep effective support, and the foot shape deviation caused by unstable gravity center is avoided; when the moderate longitudinal acting force is applied, as shown in fig. 10, the cushioning performance of the cushioning element 1 is still mainly reflected in the first deformation region 10, the connecting part 11 has a large deformation amplitude, the original upward-bulging radian is changed into downward bending, the rest part is still kept unchanged, the connecting part 11 is subjected to energy storage in the deformation process, and after the deformation is finished, the connecting part 11 is subjected to reverse (upward) resilience force, so that the wearer can have certain resilience feedback experience when walking, the power assisting effect is achieved, and fatigue is relieved; when a large longitudinal acting force is applied, as shown in fig. 11, the cushioning of the cushioning element 1 is represented by the first deformation region 10 and the second deformation region 20, the first deformation region 10 is consistent with the behavior when a medium acting force is applied, on this basis, the bending portion 13 in the second deformation region 20 is correspondingly bent, the bending degree is in direct proportion to the magnitude of the applied force, during the bending process of the bending portion 13, the outer corner angle of the bending portion 13 is gradually reduced and energy is stored, after the deformation is finished, the outer corner angle is gradually restored, the connecting portion 11 and the bending portion 13 cooperate to provide a reasonable cushioning and rebound effect, and when the applied force is large enough, the inner corner end portions of the bending portions 13 on the left and right sides move to the longitudinal center line of the cushioning element 1 to be abutted against each other and form a mutually supporting structure, this helps the cushioning element 1 to maintain structural stability and avoid further deformation, and in response to the wearer's experience, i.e. when applying a greater pressure to the sole 100, the sole still provides a suitable supporting force, which has the effect of deeply protecting the foot of the wearer.

In another embodiment, as shown in fig. 3, the profile of the cushioning element 1 has a plurality of transverse corrugations 15, and the transverse corrugations 15 help to increase the transverse connection strength of the cushioning element 1, so that the connection between the various components is tighter, which is beneficial to ensure the structural strength for deformation and prevent the fracture phenomenon of the cushioning element 1.

In another embodiment, as shown in fig. 4, the profile of the cushioning element 1 has a plurality of longitudinal corrugations 16, the longitudinal corrugations 16 are arranged along the short sides of the cushioning element 1, and the longitudinal corrugations 16 contribute to the structural strength of the cushioning element 1 and can transmit longitudinal force along the longitudinal profile of the cushioning element 1 when the cushioning element 1 is subjected to the force, so as to provide greater supporting force.
