Example one
According to one embodiment of the present invention, a sole structure is provided, which mainly includes an upper midsole 21, a lower midsole 22, a carbon fiber member 10, and a rubber outsole (not shown in the drawings), with reference to fig. 2.
The upper insole 21 is positioned above the lower insole 22, the carbon fiber component 10 is positioned between the upper insole 21 and the lower insole 22, the rubber outsole is compounded below the lower insole 22, and the compounding process between the four can adopt pressing, laminating and the like. The material of the upper midsole 21 and the lower midsole 22 may be EVA or polyurethane, and EVA is used in this embodiment.
Referring to fig. 2, the sole is formed by connecting a front palm portion 201, an arch portion 202 and a rear root portion 203 from front to back in sequence, and the front palm portion 201 can be divided into a toe portion 2011 corresponding to the position of the toes of the user and a metatarsal portion 2022 corresponding to the position of the metatarsal bones of the user. During use, the sole generally does not bend at the toes 2011, but rather bends at the metatarsal 2022 to the arch 202.
Referring to fig. 4, taking the first carbon fiber strip 11 as an example, the first carbon fiber strip 11 may be divided into a front carbon fiber strip 111, a curved carbon fiber strip 112, an arch portion 113, and a rear carbon fiber strip 114 from front to back, wherein the first carbon fiber strip 11 extends with curvature from the curved carbon fiber strip 112 to the rear end of the arch portion 113 to conform to the sole structure of a human body. Similarly, the second carbon fiber strip 11 may be divided into the above-mentioned structures, and it also extends with a curvature at the rear end from the carbon fiber strip bending part 112 to the carbon fiber strip arch part 113 to conform to the sole structure of the human body.
The carbon fiber member 10 may be compounded between the upper midsole 21 and the lower midsole 22 of the sole, and when the carbon fiber member 10 is compounded between the upper midsole 21 and the lower midsole 22 of the sole, the front support plate 13 thereof cooperates with the front portions 111 of the first carbon fiber strips 11 and the second carbon fiber strips 12 corresponding to the half sole 201 of the sole, more particularly, the front support plate 13 corresponds to the toe position 2011 of the sole, while the front portions 111 of the carbon fiber strips correspond to the position between the toe position 2011 and the metatarsal position 2012 of the sole, while the bend 112 corresponds to the metatarsal position 2012; furthermore, the rear support plate 14 is fitted with the rear portions 114 of the first and second carbon fiber strips 11 and 12 in positions corresponding to the arch portions 202 and 203 of the sole or between the arch portions 202 and 203, and in this embodiment, referring to fig. 2, the rear support plate 14 corresponds to the rear end of the arch portion 202 and the front end of the rear root portion 203, and the arch portions 113 of the first and second carbon fiber strips 11 and 12 correspond to the arch portion 202 of the sole. Thus, the carbon fiber member 10 can be completely fittingly compounded between the upper midsole 21 and the lower midsole 22 of the shoe sole and fitted to the shape of the shoe sole.
The front support plate 13 should cover the forefoot 201 mostly, i.e. its width should approximately fit the width of the forefoot 201 of the sole, while the width of the rear support 14 should also fit the width of the rear heel 203 of the sole.
Meanwhile, it should be noted that the position of the rear supporting plate 14 may relatively move forward by some distance or move backward by some distance, and this adjustment is a part that can be implemented by itself according to the actual situation, so that redundant description of this kind of embodiment is not repeated here.
Through the structure, preceding backup pad 13, back backup pad 14 can provide the support of great area for the front portion and the well rear portion of user's sole, compare in the sole carbon plate of conventional front end bifurcation structure simultaneously, preceding backup pad 13's setting can avoid the condition emergence of the insole material that its front end fork that this kind of sole carbon plate often takes place because of being absorbed in the sole with the atress area undersize of sole, thereby can make this carbon fiber component 10's atress effect better more even, be more convenient for produce the effect to the user. Because the carbon fiber member 10 only has the first carbon fiber strip 11 and the second carbon fiber strip 12 in the carbon fiber material part, the front support plate 13 and the rear support plate 14 can adopt other materials as the elastic support force is not needed, and only the carbon fiber material is arranged at the position needing the elastic support force, thereby reducing the manufacturing cost, meanwhile, because the first carbon fiber strip 11 and the second carbon fiber strip 12 are strip-shaped structures, the carbon fiber member can be directly cut from the carbon fiber plate in the manufacturing process, the material loss rate of the carbon fiber plate can be effectively reduced, thereby effectively reducing the manufacturing cost; in addition, a lightening groove 101 is formed between the first carbon fiber strip 11 and the second carbon fiber strip 12 of the carbon fiber member 10, because the carbon fiber member 10 provides elastic supporting force for the sole of a user through the first carbon fiber strip 11 and the second carbon fiber strip 12 which are positioned at the outer sides, and simultaneously the stress area of the sole on the carbon fiber member 10 is improved by the front supporting plate 13, under the condition that the first carbon fiber strip 11 and the second carbon fiber strip 12 have enough strength, the weight of the carbon fiber member 10 can be reduced through the lightening groove 101 between the first carbon fiber strip 11 and the second carbon fiber strip 12, so that the sole is lighter, the use amount of carbon fiber materials can be reduced, and the manufacturing cost is further reduced; meanwhile, the carbon fiber member 10 has better bending resistance in the lateral direction than a conventional carbon plate for a sole because the first carbon fiber strip 11 and the second carbon fiber strip 12 are not directly connected and the weight-reducing grooves 101 are formed, and can avoid the occurrence of carbon plate fracture caused by bending in the lateral direction of a user.
Further, referring to fig. 3, the distance between the first carbon fiber strips 11 and the second carbon fiber strips 12 is gradually reduced in the extending direction from the front support plate 13 to the rear support plate 14, so that the width of the lightening grooves 101 is also gradually reduced in the extending direction from the front support plate 13 to the rear support plate 14, which allows the front portion of the carbon fiber member 10 to have better elasticity and the rear portion to have better support. Meanwhile, the structure can be well adapted to the shape that the area of the half sole part 201 of the sole is larger, and the area of the arch part 202 and the rear root part 203 of the sole is smaller.
In the present embodiment, the end surface of the front support plate 13 facing the weight-reducing slot 101 is further recessed inward to form a notch 131, and the notch 131 can reduce the weight of the front support plate 13 and provide a certain deformation capability for the front support plate 13 in the lateral direction, so as to prevent the front support plate 13 from being too fragile in the lateral direction and thus from being broken by bending.
The front support plate 13 and the rear support plate 14 are made of hard plastics, preferably TPU materials, and can be fixedly connected with the first carbon fiber strips 11 and the second carbon fiber strips 12 into a whole through an injection molding process, so that the preparation efficiency of the carbon fiber member 10 can be effectively improved.
Example two
The present invention also provides a second embodiment, which is different from the first embodiment in that a structure that is concave in the width direction is provided at a middle position in the extending direction of the first carbon fiber strips 11 and the second carbon fiber strips 12.
With particular reference to fig. 5, corresponding to the first carbon fiber strips 11, there is at least a first plane perpendicular to the extending direction of the first carbon fiber strips 11, the first plane intersects with the first carbon fiber strips at the middle position of the extending direction thereof to form a first cross section, and the first cross section is bent downward in the width direction of the first carbon fibers 11; similarly, in correspondence with the second carbon fiber strips 12, there is at least a second plane perpendicular to the extending direction of the second carbon fiber strips 12, and the second plane intersects with the second carbon fiber strips at a position in the middle of the extending direction thereof to form a second cross section, which is curved downward in the width direction of the second carbon fibers 12.
Taking the first carbon fiber strip 11 as an example, two side edges in the width direction are carbon fiber strip edges 15, and at the middle position in the extending direction thereof, more specifically, the positions of the carbon fiber strip bending portion 112 and the carbon fiber strip arch portion 113, carbon fiber strip concave portions 16 are formed in the width direction at the two positions, the carbon fiber strip concave portions 16 are smoothly depressed downward in the width direction of the first carbon fiber strip 11, and the depth of depression of the carbon fiber strip concave portions 16 is deepest at the center position in the extending direction of the first carbon fiber strip 11, and becomes shallower toward the two ends in the extending direction of the first carbon fiber strip 11, and the first carbon fiber strip 11 returns to the planar shape at the two ends in the extending direction of the first carbon fiber strip 11, that is, the carbon fiber strip front portion 111 and the carbon fiber strip rear portion 114.
