Abstract
The utility model belongs to the technical field of insoles, and particularly relates to an asymmetric reinforced fiber plate elastic insole which is characterized by comprising a reinforced fiber plate layer and an elastic shoe cushion layer, wherein the reinforced fiber plate layer is positioned above or below the elastic shoe cushion layer, and the reinforced fiber plate layer and the elastic insole are laminated to form an integrally formed finished insole structure. When the hard reinforced fiber plate layer is turned upwards, the soft elastic shoe cushion layer is downwards, so that the sole is driven to move forwards to generate boosting force to help speed up running. Meanwhile, the pushing force can be adjusted through the molding angle change of the reinforced fiberboard layer to form various angle hardness of the non-equivalent strength fiberboard, and in addition, different pushing forces can be created by different board hardness to increase comfort. When the soft elastic shoe pad layer is turned upwards, the hard reinforced fiber board layer is downwards, and the hard surface can resist sharp stone or objects on the road surface, so as to prevent puncture or travelling on the stone road surface.

Preferably, the elastic insole layer is made of one of elastic materials such as EVA, TPU, PU, PEBA, TPEE, TPE.
Preferably, the reinforced fiber sheet layer is one of carbon fiber, glass fiber or natural flax and other materials.
Preferably, the thickness of the reinforcing fiber plate layer is 0.5-3.5mm, and the thickness of the elastic shoe cushion layer is 2-20mm.
Preferably, the reinforcing fiber sheet layer is fixedly disposed at a sole position of the upper surface or the lower surface of the elastic insole layer.
Preferably, the lower surface of the reinforced fiber sheet layer is inlaid on the upper surface or the lower surface of the elastic insole through technologies such as lamination, injection molding or mould pressing.
Preferably, the elastic shoe pad layer is provided with a multi-layer structure, the reinforcing fiber plate is arranged between the elastic shoe pad layers, and the upper surface and the lower surface of the reinforcing fiber plate layer are inlaid on the elastic insole through technologies such as laminating, injection molding or mould pressing.
The utility model has the beneficial effects that:
the utility model forms the integrated finished insole structure by laminating the reinforced fiber board layer and the elastic insole. The asymmetric insole construction provides a hard rebound and a soft rebound. The bidirectional asymmetric rebound can be completely matched with the human motor. When the hard surface is upward and the soft surface is downward, the human body biological function test analysis shows that when the foot is stepped down, the toe can be downward bent, and the soft surface is downward, so that the toe can press the hard reinforced fiber board layer without applying force, the burden of the lower leg can be relieved, and meanwhile, the hard reinforced fiber board layer can be turned upward along with the bending of the sole during walking, thereby pushing the sole to move forward to generate boosting force to help speed up running. Meanwhile, the pushing force can be adjusted through the molding angle change of the reinforced fiberboard layer to form various angle hardness of the non-equivalent strength fiberboard, and in addition, different pushing forces can be created by different board hardness to increase comfort.
In another embodiment, the soft side of the elastic shoe pad layer is downward with the hard and soft side of the fiber reinforced plate layer, so that the pressure of the sole on the sharp object can be dispersed, puncture is reduced, and protection and comfort are improved.

Detailed Description
The details of the present utility model are described below in conjunction with the accompanying drawings and examples.
Referring to fig. 1 to 3, embodiment 1 provides an asymmetric reinforcing fiber board elastic insole, comprising a reinforcing fiber board layer 11 and an elastic insole layer 12, the reinforcing fiber sheet layer 11 is positioned above the elastic shoe cushion layer 12, and the reinforcing fiber sheet layer 11 and the elastic shoe cushion layer 12 are overlapped to form the integrated finished insole structure 1.
Further, the elastic shoe pad layer 12 is made of foam EVA, thermoplastic elastomer TPU, polyurethane PU, resin PEBA, thermoplastic polyester elastomer TPEE, thermoplastic elastomer TPEE, or a combination of one or more fiber materials.
Further, the reinforcing fiber board layer 11 is formed by mixing and weaving one or more fiber materials of carbon fiber, glass fiber, natural flax and the like. In another embodiment, the reinforcing fiber sheet layer 11 may be glued with a thermosetting epoxy resin and reinforcing fibers.
Further, the reinforcing fiber sheet layer 11 has a thickness of 1mm, and the elastic insole layer 12 has a thickness of 3mm.
Further, in order to obtain different pushing force effects and comfort, the finished insoles with different pushing force are manufactured through various process technologies such as lamination, injection molding, mould pressing and the like through the plastic molding angle change of the reinforced fiberboard layer 11.
The finished insoles with different driving forces are manufactured by adjusting the hardness of the plates and adopting a plurality of process technologies such as lamination, injection molding, mould pressing and the like.
