New description: [New technical field] This creation mainly reveals a bicycle composite material, especially a spoke that can reduce wind resistance and has good wind cut. [Prior Art] Refer to the attachment 'For the Republic of China Patent No. M294434 "Bicycle Spokes" patent case, after the bicycle spokes are formed and mounted on a wheel, the curved head can be flat on the outside of the wheel hub. In order to prevent the spoke from vibrating due to the gap when the bicycle is running, it is damaged. And by the design of the neck, it is not easy to break and can support more weight. However, the shaft of the conventional spoke is designed as a solid cylindrical strip. The cylindrical structure cannot effectively reduce the wind resistance during the running of the wheel, and the solid structure is not only heavy and costly, but also the spokes are in the process of traveling. The alternating changes of tensile force and pressure make the spokes easily accumulate stress, which in turn causes the spokes to break. For the above problems, it is necessary to improve. In view of the above-described deficiencies in the conventional structure, the present author has created a bicycle composite spoke that overcomes all of the above-mentioned disadvantages of the conventional structure. 'New Content】 The technical problem to be solved by this creation is to provide a bicycle composite spoke for the above-mentioned shortcomings of the prior art.

The end wall 1311 of the side wall 1312 is opposite to the cut surface 111 and the side surface 112, so that the body portion n forms an equal wall ^ Torn round section. The second hollow portion 132 has a circular hollow shape, and the angle connecting portion 12 is formed into a circular cross section of uniform wall thickness. The cut surface 111 JL has good wind cutability and can cause the air flow to bypass the body u along the two side faces 112, thereby effectively reducing the wind resistance. The connecting portion 12 has a circular surface 121. The distance between the two-phase flank 111 is greater than the distance of the connecting portion 12. The distance between the opposite sides 112 is smaller than the distance between the two opposing surfaces 121, so that the body η forms an ellipse. The shape of the section. The body portion 11 has a neck portion 4 between the connecting portion 12, and the neck portion 14 is connected by the connecting portion 丨2 to the neck portion 14 to where the body portion 11 meets the neck portion 14 by a circle The shape of the section is changed into an elliptical cross section, and the body portion 11 is a section of the same rounded shape from the neck portion 14 to the middle portion of the body portion 11, and the body portion η, the connecting portion 12 and the neck portion The portions 14 are all equal wall thicknesses. The surface of the coupling member 20 has a threaded portion 21 and a joint portion 22, and the threaded portions 21 of the two coupling members 20 are screwed and coupled to the wheel frame 3Q and the flower hub 4' respectively, so that the pedaling kinetic energy can be directly driven by the flower hub 4〇. Box % reduces the loss of kinetic energy without wasting extra effort. The joint portion 22 is coupled to the joint portion 12. Referring to Figures 5 and 6, the hollow structure of the bicycle spoke can reduce the weight of the spoke 1 and meet the current demand for lightweight bicycles. Moreover, under the condition of the same shape and size, the solider wheel saves the cost of materials, and the shape changes are more diverse, so as to provide customers with various levels of demand. It is more worthwhile to mention that the elasticity of the hollow light strip is good enough to withstand the stress caused by the tension and pressure of the spokes, so that the stringer 1 is not easily broken. As shown in Figure 6, the secret can effectively reduce the wind. The wind has good wind cutability. It can effectively guide the airflow to the two sides 112 and use the circular structure to effectively reduce the generation of eddy currents. Suitable for long distance rides. Figure 7 and Figure 8 show a perspective view and a cross-sectional view of a second embodiment of the present invention. The second embodiment is substantially identical to the first implementation f'J described above, with the difference being in the body 丨〇a. Referring to FIG. 9 to FIG. 10 simultaneously, the body of the body 1Qa is formed with two opposite cut faces 111a and two opposite side faces, and the body portion is formed into a bilaterally symmetrical shape with the virtual center line S as an axis. The thickness of the cut surface Ilia is increased by the curved surface of the body Ua and the connecting portion to the center line, and the body portion 11a and the connecting portion are all circular and hollow. The stronger the structural strength near the centerline is to prevent the rim 1a from being η, 、, 武, and the stress is broken. The thickness of the side 112a is connected to the connection by the body 11a.相12a meets to the center line S is the same wall thickness 'the face 11 la and has _ recognition door ^ _ 110 /, has good wind cutability and can make the air flow around the body lla along the two sides H2a, Effectively reduce the wind resistance. Referring to Figure 12, the use state diagram of the first method of the creation of the flute _ ^ 1 ^ \ ,, the two ends of the spoke la are screw-locked to the wheel frame 30 and the flower hub 40 respectively, so that the pedaling is performed. Move M358066 directly from Huaxu 40 drive wheel frame 3q to reduce the loss of kinetic energy. As mentioned above, it can be concluded that this creation has Advantages of the following ··· & The creation of "bicycle composite spokes", in which the bicycle spokes are effective enough to reduce the weight of the noodles, in line with the current demand for lightweight bicycles, the cost of materials can be saved, and the flexibility of hollow spokes The Canon dog bears the tensile force and dynamic contact stress of the spokes, so that the spokes are not easy to break. 2. The bicycle composite spokes of this creation have various characteristics to meet the needs of customers at all levels. The above description is only a preferred embodiment of the present invention, and when it is not possible to limit the implementation of the present invention, the replacement of the equivalent component of the numerical value is as follows. Equal change and modification 's should still be covered by this new patent.
