Description of the invention: [Technical field to which the invention pertains] The present invention mainly discloses a crank structure and a manufacturing method thereof, and particularly an innovative process developed by comparing the principle of human bones and bones, and can exert the expected strength and lightness. Quantitative performance of the "bone-structured carbon fiber composite bicycle crank and its manufacturing method [prior art] crying material = moving; material is the part of the human hand and foot extension line, by the use of sports materials, the purpose of the game , and transport _ material, is "handle. Good sports equipment, not only to take care of comfort, 2 thieves material" but also to play Wei's performance of the largest Weinan performance of sports coffins, no more than the use of complex and good quality, In order to fully match the customer's s, the customer complains about the credit quality or complains about the performance quality of the hand: the resulting passenger = the shape of the bicycle crank, the main fine early iron evolution into a composite _ green clothing from the crank is heavier, —Quantity (4)^Crank made of material made of Wang metal material%2=Use non-metal materials please refer to Figure 8 - Metal plate (4) _ /, shank structure 9g' including cap 902盥_, > and the metal 902 disposed at the two ends of the metal strip body 901 and the private slats (four) 丨 and the two outer surfaces are again provided - composite material _, county composition === 200829472 9 〇 compared to In the case of the structure of the conventional all-metal crank, the lightweight metallurgical fruit is produced. However, since the metal strip body 901' which has a strip shape in the crank structure 90 is a slightly heavy structure, it is lightweight. There is still room for improvement in design. - Reference, Fig. 9 is a crank structure 91 having a foamed material, which comprises a thick plate-shaped foam body 911 made of a foam material, the foaming The body 911-' is respectively provided with a metal cap 912, 913, and the foam body 911 and the two metal caps 912, 913 are integrally covered with a composite material 914' to thereby form a crank structure 91. The foregoing problem of slightly using the aluminum core is improved. Referring to FIG. 10, a structure of a hollow crank 92 includes two metal caps 921, 922 and a first strip shape longitudinally surrounding the outer sides of the two metal caps 921, 922. The composite material 923 is attached to the first strip composite 923 at the time of manufacture A nylon air bag 925 is disposed, and then the second strip-shaped composite material 924' is vertically and laterally overlapped on the outer side of the first strip-shaped composite material 923 and the nylon air bag 925, and then placed in a mold and filled in a nylon air bag g25. The high-pressure gas is heated and the strip-shaped composite materials 923 and 924 are hardened and formed. Since the air bag must have an air inlet, after the molding, the air-inlet hole left at the tail end of the crank, in addition to affecting the structural strength, is difficult to handle, and After the rough embryo is completed, the residual exit hole needs to be filled with additional material beautification appearance. Although the process has a hollow purpose, the manufacturing process is difficult, the structure is broken, and the post-treatment is improved, and the space is improved. Compared with the conventional structure mentioned above, the design of 92 can achieve a lighter weight effect, but the disadvantage is that it uses the air blowing method to make 200829472, so the wall thickness of each part of the hollow crank 92 cannot be controlled to be exactly the same. Dimensions, the inspection of defective products, especially the difficulty of pre-structure coating caused by the reading, the tU mouth system after molding, which in turn affects the structural strength, resulting in easy product defects. Point. In the absence of the above-mentioned conventional structure, the inventors have invented a "carbon fiber composite bicycle crank and a manufacturing method thereof" which overcomes all the disadvantages of the above-mentioned conventional structure.
