Technical Field

[0001] The utility model relates to the technical field of sports shoes, in particular to a sports shoe sole structure. Background Art

[0002] Sports shoes are shoes designed and manufactured according to the characteristics of people participating in sports or traveling. The soles of sports shoes are different from ordinary leather shoes and rubber shoes. They are generally soft and elastic, which can play a certain cushioning role, enhance elasticity during exercise, and some can also prevent ankle injuries. Therefore, when doing sports, most people have to wear sports shoes, especially high-intensity physical sports, such as basketball, running, and various daily sports.

[0003] Most of the soles of existing sports shoes are integral injection-molded or foamed structures, and uneven patterns are arranged on the soles to achieve the anti-slip function. The grooves and other patterns on the bottom of the soles cannot be opened too deep, otherwise it will affect the structure of the soles, causing the soles to be damaged or broken. This also leads to more solid parts of the soles, lacking sufficient gaps for stress deformation, and the deformation space of the soles is small, which affects the shock absorption effect. At the same time, the weight of the soles is large, which is not light enough during exercise, and there are some shortcomings in use. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: a sports shoe sole structure, including an outsole 1, a midsole sheet 2, an elastic midsole 3 and a wear-resistant bottom layer 4, wherein the midsole sheet 2 is arranged at the bottom of the outsole 1, the elastic midsole 3 is arranged at the bottom of the midsole sheet 2, and the wear-resistant bottom layer 4 is arranged at the bottom of the elastic midsole 3.

[0019] The outsole 1 and the elastic midsole 3 can be formed by adding ultra-light and highly elastic polyurethane foam to EVA material, and the multi-component polyurethane contained therein is blended to form a network interpenetrating VPN physical cross-linking structure, which can produce a foaming professional material with the characteristics of softness, high elasticity, low compression, and anti-slip. The wear-resistant bottom layer 4 can be made of rubber material with good wear resistance.

[0020] The elastic midsole 3 includes an outer midsole 31 and an inner midsole 32. The outer midsole 31 is a hollow annular structure. The front and rear ends of the upper surface of the outer midsole 31 form a concave supporting portion 311. The two ends of the inner midsole 32 form a protruding fixing portion 321 for splicing with the supporting portion 311. The middle section of the inner midsole 32 forms a strip structure that can be embedded in the middle cavity of the outer midsole 31. Both sides of the outer midsole 31 form a first corrugated portion 312 along its length direction. The strip structure in the middle section of the inner midsole 32 forms a second corrugated portion 322 along its length direction. The peaks and troughs of the first corrugated portion 312 are staggered with the peaks and troughs of the second corrugated portion 322.

[0021] The elastic midsole 3 is composed of an outer midsole 31 and an inner midsole 32, which are manufactured and formed separately and then spliced ​​and connected to form a whole. The two ends of the outer midsole 31 and the two ends of the inner midsole 32 are respectively contours adapted to the heel and toe of the shoe and are stacked up and down, and the middle section of the outer midsole 31 and the middle section of the inner midsole 32 are combined to form a contour adapted to the sole of the shoe. When splicing and connecting, the fixing parts 321 at the two ends of the inner midsole 32 are attached to the supporting parts 311 at the two ends of the outer midsole 31 and bonded to connect the two.

[0022] A cavity is formed in the middle of the outer midsole 31, and the size of the strip structure in the middle section of the inner midsole 32 is adapted to the cavity. When the outer midsole 31 and the inner midsole 32 are connected to form a whole, the strip structure in the middle section of the inner midsole 32 is just embedded in the cavity, and the combination forms a complete midsole.

[0023] The outer midsole 31 and the inner midsole 32 are respectively bonded to the bottom of the midsole sheet 2 , and the fixing portion 321 of the inner midsole 32 is bonded to the supporting portion 311 of the outer midsole 31 .

[0024] The trough parts of the first corrugated part 312 and the second corrugated part 322 are located at the bottom, and the peak parts are located at the top and connected to the two sides and the middle of the middle section of the midsole sheet 2; grooves are formed on the upper surfaces of the two ends of the inner midsole 32 to accommodate the two ends of the midsole 2 and thus connect to the two ends of the bottom of the midsole sheet 2.

[0025] The midsole sheet 2 is bonded to the bottom of the outsole 1. The midsole sheet 2 should be supported by a material having a hardness slightly greater than that of the elastic midsole 3, so as to play a role in supporting and dispersing the force.

[0026] At this time, from the side view (such as Figure 3 As shown in the perspective, the bottom lines of the trough parts of the first corrugated part 312 and the second corrugated part 322 overlap and together form a complete contact surface for bearing the force of contact with the ground, so that under any cross-sectional perspective of the end (not shown in the figure), there must be a trough part of the first corrugated part 312 or the second corrugated part 322 to form a bottom contact surface for bearing the force of contact with the ground, and there will be no situation where a certain cross section is in a supporting vacuum and lacks a contact surface.

[0027] When the trough part is subjected to the reaction force of the ground, the force will be transmitted upward to the crest, and then transmitted upward from the crest. Since the top area of ​​the crest is small, it can be understood that a point on the midsole 2 is subjected to the force transmitted from the crest. Since the midsole 2 is a complete sheet structure, the force can be dispersed at this time so that it does not only act on one point on the midsole 2, but also is transmitted upward to the complete outsole 1, and then further dispersed by the outsole 1, so that the force acts on the outsole 1 to the greatest extent, and thus is evenly transmitted to the sole of the foot, without causing a feeling of hurting the foot in a certain place.

[0028] By setting the elastic midsole 3 as a structure formed by the combination of the outer midsole 31 and the inner midsole 32, and the sole parts of the outer midsole 31 and the inner midsole 32 are set as inner and outer interlocking structures, and the sole parts are provided with mutually staggered corrugated structures, a complete contact surface can be formed at the bottom, and a large number of deep cavities can be formed at the bottom. On the one hand, it can effectively reduce weight, and on the other hand, it leaves enough deformation space for the solid part, so that the trough part can produce enough deformation when subjected to force to offset the impact force and reaction force, and has a buffering and shock-absorbing effect, so that the entire sole has better elasticity and is lighter.

[0029] A side wall 21 that bends and extends upward is provided at the rear portion of the outer side edge of the midsole sheet 2 , and the side wall 21 is bonded to the outer side of the outsole 1 .

[0030] The wear-resistant bottom layer 4 is bonded to the bottom of the elastic midsole 3, and the position of the wear-resistant bottom layer 4 corresponding to the crests of the first corrugated portion 312 and the second corrugated portion 322 is set as a hollow structure. The bottom of the wear-resistant bottom layer 4 is provided with anti-skid patterns, and the position of the wear-resistant bottom layer 4 corresponding to the trough and the two ends of the bottom of the outer midsole 31 is a solid part, and the position corresponding to the crests of the first corrugated portion 312 and the second corrugated portion 322 is hollowed out to achieve a weight reduction effect, and multiple hollow hole structures can enhance the anti-skid effect.
