Description

Technical Field

[0001] The utility model relates to the field of bicycle shoes, and particularly to a sole structure of a bicycle shoe. Background Art

[0002] Most of the structures of traditional bicycle shoe soles are combined with a layer of carbon fiber composite material on the bottom surface of the sole. Due to the high strength, wear resistance, corrosion resistance and light weight of the carbon fiber composite material, the bicycle can be made more durable and light. When processing such a bicycle sole, the carbon fiber is first directly bonded to the sole, and then the upper shoe is bonded to the sole, so that the sole is between the carbon fiber and the upper shoe. However, in order to ensure the strength and wrapping property of the bicycle shoe, the upper shoe generally adopts a non-breathable and non-elastic upper shoe. In this way, the overall breathability of the bicycle shoe is poor.

[0003] In view of this, the inventor of this case has conducted in-depth research on the above problems, and thus this case has been produced. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sole structure of a bicycle shoe with good breathability.

[0005] In order to achieve the above purpose, the utility model adopts such a technical solution:

[0006] A sole structure of a bicycle shoe includes a sole and a carbon fiber board. The sole has a forefoot area, an arch area and a heel area which are arranged in sequence from front to back. It also includes a rigid breathable sheet. The above sole is an injection-molded sole. The above rigid breathable sheet is stacked on the carbon fiber board. The carbon fiber board and the rigid breathable sheet are injection-molded with the sole inlaid and are located inside the sole. A closed-loop groove is recessed on the lower bottom surface of the sole within the ranges of the forefoot area, the arch area and the heel area. A partial part of the carbon fiber board is located within this closed-loop groove. Through holes penetrating up and down are opened on the carbon fiber board. The rigid breathable sheet is arranged in vertical alignment with the through holes. The size of the rigid breathable sheet is larger than that of the through holes. A number of breathable pores are densely arranged within the range of the through holes on the rigid breathable sheet. An exposed hole for each breathable pore to fall into is opened on the upper surface of the sole at the position of the rigid breathable sheet.

[0007] A side edge protruding upward along the contour direction of the heel area is provided on the upper surface of the above sole at the heel area.

[0008] A positioning hole is opened on the carbon fiber board at the heel area. A positioning block protruding downward out of the positioning hole is provided on the sole corresponding to the positioning hole.

[0009] Lower ventilation holes are opened on the carbon fiber board at the forefoot area. Upper ventilation holes communicated with the lower ventilation holes are opened on the upper surface of the sole at the positions of the lower ventilation holes.

[0010] The above-mentioned rigid breathable sheet is arranged in the above-mentioned arch area, and a plurality of positioning pin holes are arranged at positions of the rigid breathable sheet outside the through-hole range and are distributed at intervals and circumferentially around the rigid breathable sheet.

[0011] The above-mentioned rigid breathable sheet is a steel sheet.

[0012] In the forefoot area of the above-mentioned sole, two of the above-mentioned rigid breathable sheets are arranged at intervals in the left-right direction on the front side of the closed annular groove, and through holes penetrating up and down for the rigid breathable sheets to be exposed are correspondingly arranged on the sole corresponding to the two rigid breathable sheets.

[0013] After adopting the above technical solution, in a sole structure of a bicycle shoe of the present utility model, the cooperation between the breathable pores and the exposed holes on the rigid breathable sheet enables the bicycle sole to have excellent breathability, and the rigidity of the rigid breathable sheet can ensure the strength of the bicycle sole. At the same time, the carbon fiber board, the rigid breathable board and the sole are integrally injection-molded in a mold to ensure the stable installation of the carbon fiber board and the rigid breathable board, and significantly improve the processing speed of the bicycle sole, avoiding the problem of low production efficiency caused by the traditional carbon fiber board being attached. Description of the Drawings

[0014] Figure 1 is an exploded perspective view of the present utility model;

[0015] Figure 2 is a perspective view of the present utility model. Detailed Embodiments

[0016] In order to further explain the technical solution of the present utility model, the following will be elaborated in detail with reference to the drawings.

[0017] A sole structure of a bicycle shoe of the present utility model, as Figure 1-2 shown, includes a sole 1, a carbon fiber board 2 and a rigid breathable sheet 3. The sole 1 has a forefoot area, an arch area and a heel area arranged in sequence from front to back. The sole 1 is an injection-molded sole. The rigid breathable sheet 3 is stacked on the carbon fiber board 2. The carbon fiber board 2 and the rigid breathable sheet 3 are integrally injection-molded with the sole 1 and are inside the sole 1. Specifically, first place the rigid breathable sheet 3 in the molding cavity for molding the sole, then place the carbon fiber board 2 in the molding cavity and above the rigid breathable sheet 3, and then close the mold. After closing the mold, inject the injection plastic for molding the sole into the molding cavity, and the integral inlay injection molding of the carbon fiber board 2, the rigid breathable sheet 3 and the sole 1 can be realized.

[0018] The lower bottom surface of the sole 1 is concavely provided with a closed annular groove 11 falling within the forefoot area, arch area, and heel area. A partial portion of the carbon fiber plate 2 is located within this closed annular groove 11. The carbon fiber plate 2 is provided with a through hole 20 penetrating up and down. The through hole 20 is preferably arranged corresponding to the arch area of the carbon fiber plate 2. The through hole 20 is preferably a closed-loop arc-shaped hole that is larger at the front and smaller at the rear. The rigid ventilation sheet 3 is arranged in vertical alignment with the through hole 20. The rigid ventilation sheet 3 is preferably made of a steel sheet. The size of the rigid ventilation sheet 3 is larger than the size of the through hole 20. By making the size of the rigid ventilation sheet 3 larger than the size of the through hole 20, the edge of the rigid ventilation sheet 3 can be pressured by the sole pressure during injection molding, making the installation of the rigid ventilation sheet 3 more stable. The rigid ventilation sheet 3 is densely provided with a number of ventilation pores 30 within the range of the through hole. The shape formed by each ventilation pore 30 is the same as the shape of the through hole 20. An exposed hole 12 for each ventilation pore 30 to fall into is provided on the upper surface of the sole 1 at the position of the rigid ventilation sheet 3. By means of this exposed hole 12, each ventilation pore 30 is exposed on the upper surface and the lower bottom surface of the sole.

[0019] For a sole structure of a bicycle shoe of the present utility model, during application, the shoe upper can be directly pasted on the upper surface of the sole 1 to complete the production of the bicycle shoe. During use, the hot air inside the bicycle shoe flows downward through the exposed hole to the ventilation pores on the rigid ventilation sheet 3, and finally flows out through the through hole from the closed annular groove, achieving a heat dissipation effect, making the entire bicycle shoe have a ventilation effect. At the same time, by using the arrangement of the ventilation pores and the closed annular groove, the rigid ventilation sheet is not flush with the bottom surface of the sole, thereby making the ventilation effect better. Moreover, by using the rigidity of the rigid ventilation sheet 3, the strength of the bicycle sole can be ensured. At the same time, the carbon fiber plate 2, the rigid ventilation plate 3, and the sole 1 are integrally injection molded in a mold to ensure the stable installation of the carbon fiber plate 2 and the rigid ventilation plate 3, and significantly improve the processing speed of the bicycle sole, avoiding the problem of low production efficiency caused by the traditional way of attaching the carbon fiber plate.

[0020] Preferably, the upper surface of the sole 1 is convexly provided with a side edge 13 extending along the contour direction of the heel area in the heel area. By means of this side edge 13, after the shoe upper is installed, the side edge is tightly attached to the shoe upper, playing a role in tightening the heel and ensuring safe wearing.

[0021] Preferably, the carbon fiber plate 2 is provided with positioning holes 21 in the heel area. Preferably, there are two positioning holes 21, and the two positioning holes 21 are arranged side by side at intervals in the left-right direction. The positioning holes 21 are preferably strip-shaped holes arranged in the front-rear direction, and the strip-shaped holes are shaped like special-shaped holes that are smaller at both the front and rear ends and larger in the middle. The sole 1 is convexly provided with positioning blocks 12 protruding outside the positioning holes 21 corresponding to the positioning holes 21. The positioning blocks 12 are tightly fitted with the positioning holes 21. By means of these positioning blocks 12, the sole 1 and the carbon fiber plate 2 can be firmly clamped together. At the same time, the use of the strip-shaped hole shape that is smaller at both ends and larger in the middle makes the clamping degree of the positioning block more compact.

[0022] Preferably, the carbon fiber plate 2 is provided with lower ventilation holes 22 in the forefoot area. Preferably, there are three lower ventilation holes, which are strip-shaped holes extending in the front-rear direction. Among the three lower ventilation holes, two of them are arranged at intervals in the left-right direction, and the other lower ventilation hole is located in front of and between the two lower ventilation holes. The upper surface of the sole 1 is provided with ventilation holes 14 corresponding to each lower ventilation hole 22 and communicating with the lower ventilation holes. The ventilation holes 14 are also strip-shaped holes accordingly. The ventilation performance of the sole in the forefoot area can be increased by using the structure of the ventilation holes.

[0023] Preferably, the rigid ventilation sheet 3 is provided with a plurality of positioning pin holes 31 that are circumferentially and spacedly distributed around the rigid ventilation sheet at a position outside the range of the through hole 20. The positioning pin holes 31 can be used to facilitate the positioning of the rigid ventilation sheet 3 in the molding die.

[0024] Another preference is that two rigid ventilation sheets 4 are provided outside the front side of the closed annular groove in the forefoot area of the sole 1 at intervals in the left-right direction. Correspondingly, the sole 1 is provided with through holes for exposing the rigid ventilation 4 at the positions of the rigid ventilation sheets 4. The ventilation effect can be significantly improved by using the two rigid ventilation sheets 4.

[0025] The product form of the present utility model is not limited to the illustrations and embodiments of this case. Any person who makes appropriate changes or modifications to it with a similar idea should be regarded as not departing from the patent scope of the present utility model.
