AI Technical Summary
Existing racing shoes suffer from a lack of effective mechanical support in the hollowed-out areas during high-speed running, leading to a decrease in instantaneous stability and affecting the athlete's gait control. Furthermore, the insufficient deformation range of traditional rigid support frames affects the sustainability of energy output.
The design employs a suspended carbon plate structure, which suspends a carbon plate layer within a channel running through the middle layer of the sole. Combined with an asymmetrical channel and raised ramp design, it forms a double-through mechanical chamber, enhancing deformation space and energy feedback. Stability is further improved through a wrap-around fit structure that cushions the upper layer and supports the lower layer.
It improves the stability and energy transfer efficiency of running shoes under extreme deformation, ensuring dynamic stability and continuous energy output, and avoiding the shortcomings caused by local hollowing or rigid support in traditional designs.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of shoes, specifically relates to a kind of suspended carbon plate shoe sole. BACKGROUND
[0002] The mainstream carbon plate racing shoes realize the leap of sports efficiency by improving the formula of midsole and the form of carbon plate, which has approached the limit of physical performance. In the mechanical model of racing shoes, the conversion of deformation energy storage and energy feedback directly determines the propulsion efficiency. How to build a better deformation conduction system has become a key technical bottleneck restricting product upgrading.
[0003] Currently, local hollow design is usually used to enlarge the deformation space, such as setting open cavity in the forefoot or heel area. Although this treatment can improve the local deformation, it will lead to a decrease in instantaneous stability when the foot touches the ground during the off-ground stage of high-speed running, especially in multi-bend tracks or uneven road conditions, which easily causes lateral sliding risk and affects the gait control of athletes. Further improvement is to use a hard support frame with a local hollow structure, such as embedding a single-layer composite plate in the midsole. Although this design can improve the support strength, the actual deformation amplitude of the hollow area below is often difficult to achieve the theoretical expectation due to the deformation threshold limit of rigid materials, which will affect the energy output sustainability of athletes in long-distance races.
[0004] Therefore, the utility model provides a kind of suspended carbon plate shoe sole. Through the mechanical conduction path design of suspended carbon plate structure, a dynamic deformation unit is built in the single-layer support system, which improves the dual performance of shock absorption and rebound while ensuring dynamic stability and energy conduction efficiency in high-speed motion. SUMMARY
[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of a kind of suspended carbon plate shoe sole, which includes a buffer upper layer, a middle carbon plate layer and a bearing lower layer. The buffer upper layer and the bearing lower layer are provided with a notch in the arch area. The notch forms a channel through the inside and outside of the shoe sole in the arch area after the combination of the buffer upper layer and the bearing lower layer. The middle carbon plate layer penetrates through the channel and is suspended in the channel, so that the channel is divided into an upper channel and a lower channel.
[0006] Further, the buffer upper layer is provided with a first raised slope in the upper channel.
[0007] Further, the bearing lower layer is provided with a second raised slope in the lower channel.
[0008] Further, the first raised slope and the second raised slope are designed asymmetrically.
[0009] Further, the channel is approximately parallelogram-shaped.
[0010] Further, the intermediate carbon plate layer is provided with wave-shaped reinforcing ribs.
[0011] Further, the buffer upper layer and the load-bearing lower layer are respectively provided with grooves matched with the wave-shaped reinforcing ribs.
[0012] Further, the front-palm-side edges and the heel-root-side inner recesses of the buffer upper layer form grooves.
[0013] Further, the front-palm-side upturned edges of the load-bearing lower layer form annular constraint bands matched with the front-palm-side edge grooves of the buffer upper layer.
[0014] Further, the heel upturned edges of the load-bearing lower layer form fly tails matched with the heel-root-side grooves of the buffer upper layer.
[0015] Further, the load-bearing lower layer is provided with a sole matching area.
[0016] With the above technical solution, the beneficial effects of the utility model are as follows: the asymmetric channel design of the intermediate carbon plate layer penetrating the arch area, the double-penetration type mechanical cabin breaks through the limitation of the traditional design, compared with the traditional single-cavity structure, the deformation space of the upper and lower linkage makes the energy storage efficiency of the midsole higher, and more sufficient energy feedback is provided for the stretch stage. Meanwhile, the design of the asymmetric channel strengthens the overall torsional stiffness of the sole, and the wrap-around matching of the buffer upper layer and the load-bearing lower layer can make the running shoes still maintain a stable landing posture under extreme deformation.

[0024] To illustrate the technical content of the utility model, the purposes and effects achieved, the following will be described in conjunction with the embodiments and the accompanying drawings.
[0025] As shown in Figure 1 , 2 , a suspended carbon plate shoe sole comprises a buffer upper layer 1, a middle carbon plate layer 2 and a load-bearing lower layer 3. The buffer upper layer 1 and the load-bearing lower layer 3 are provided with notches in the arch area, and the notches of the buffer upper layer and the load-bearing lower layer form a channel 4 through the inside and outside of the sole in the arch area after the combination of the two. The window of the channel 4 on the inside and outside of the sole is approximately a parallelogram. The middle carbon plate layer 2 penetrates through the channel 4 and is suspended in the channel, so that the channel is divided into an upper channel and a lower channel. The double-penetration mechanical cabin breaks through the limitations of traditional design. Compared with the traditional single-cavity structure, the deformation space of the upper and lower linkage makes the energy storage efficiency of the midsole higher, provides more abundant energy feedback in the extension stage, and realizes the suspended visual effect in the single-layer rigid structure.
[0026] The buffer upper layer is provided with a first raised slope 11 in the upper channel, and the load-bearing lower layer is provided with a second raised slope 31 in the lower channel. The first raised slope and the second raised slope are asymmetrically designed in the channel. The design of the asymmetric channel strengthens the overall torsional stiffness of the sole.
[0027] As shown in Figure 3 , 4 , the edges of the forefoot of the buffer upper layer are concave to form a first groove 12, and the edges of the forefoot of the load-bearing lower layer are upward to form an annular restraint band 32. When the buffer upper layer and the load-bearing lower layer are combined, the groove of the forefoot of the buffer upper layer and the annular restraint band of the load-bearing lower layer are mutually fitted. The heel root of the buffer upper layer is concave to form a second groove 13, and the heel of the load-bearing lower layer is upward to form a fly tail 33. When the buffer upper layer and the load-bearing lower layer are combined, the heel groove of the buffer upper layer and the fly tail of the load-bearing lower layer are mutually fitted. This wrapped fitting structure controls the disordered diffusion of materials while releasing the deformation space, and improves the energy conversion efficiency through space reconstruction without increasing the number of functional layers, so that the running shoes still maintain a stable landing posture under extreme deformation.
[0028] The load-bearing lower layer is also provided with a region for the adhesion of the outsole, which increases the wear resistance of the sole.
[0029] As shown in Figure 3 , 4 , 5, the middle carbon plate layer is provided with a wave-shaped reinforcing rib 21. The buffer upper layer and the load-bearing lower layer are respectively provided with grooves for the adhesion of the wave-shaped reinforcing rib.

Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
