Description of the new type: [Technical field to which the new type belongs] This series is about a kind of carbon fiber bicycle rim, especially a Weiwei bicycle wheel structure improvement by connecting the miscellaneous _ 之 支. [Previous technology] The materials used in the manufacture of bicycles have changed from iron or stainless steel in the past to become the most commonly used alloy. The use of Ming alloy can make the car body heavier, but in order to make the car body lighter weight ', there are now more bicycles made of carbon fiber. The use of Yunwei as a raw material has the advantage of light weight, but its cost is higher than that of ordinary Shao alloys. Under normal circumstances, most of the frames are only used before and after the frame f as the scope of application of this material, but in terms of racing bicycle racing%, the weight of the entire vehicle is a very important consideration, so the entire vehicle is as much as possible = use quality Lightweight carbon fiber for the body. Therefore, even the rims are made of carbon fiber. Carbon fiber wheels _ made, should be considered. ^ In terms of weight reduction, so now known carbon fiber wheels on the market are hollow lion wheels. After the carbon impurities are hard-reduced, their extension f is reduced by 1. The hollow structure is often lacking in strength and damaged when the rim is stressed. Therefore, there are known creations that use the left and right half of the frame to relatively combine to produce an improved rim structure with vertical support ribs. Although it can increase the strength of the rim, the Y Bali method is made by the left and right frames. It is made by inserting. It is not only necessary to set another mold 5 M268199 to make different frames. After the frame is made, the left and right frames need to be tightly connected by high-strength gluing technology. Increase the equipment, materials, cost and time required for the manufacturing process. [New content] In order to improve the strength of the fiber rim, and to reduce the steps required in the manufacturing process, and reduce the cost and time, this creation will provide a support wall connecting the inner wall of the rim to strengthen the structure of the rim. Improved carbon fiber rim structure. This project includes a stone anti-fiber rim, which is a ring-shaped hollow structure formed by an upper wall and a lower wall with two left and right side walls. The hollow part of the rim is also provided with a series of wheels. Touch it. The trapped wall of the lateral branches of the left and right side walls, the vertical branch 垂直 perpendicular to the upper and lower walls, and the cross supporting wall including the former two, to increase the strength of the rim to adapt to the rim's vibration. The impact force received during impact protects the structure of carbon fiber and the rim itself. Because of this creation, the use of financial molds is purely improved in the manufacturing process, so that the integrally formed% fiber is converted, so the manufacturing process is non-contact and splicing, which can reduce the number of systems. It also does not require additional molds and does not increase. Expenditure on costs. On the other hand, ^ The cutting wall produced by the creative improvement, _ beside the vertical support wall in the straight direction, there are = horizontal catches such as horizontal catches and support shots with a cross between the straight and the water. Silk or different structures: The scope of its use is also wider than that of conventional creation. M268199 [Embodiment] Please refer to the first and second drawings, which are cross-sectional views of the first embodiment of the creation. This creation includes a bicycle carbon fiber rim 10, which is composed of an upper wall 12 and a lower wall 13 and two. The side walls 14 are connected to define a hollow ring. The upper wall 12 has a concave circular arc configuration, and a tire groove 11 corresponding to the tire 20 is located above the tire. The tire 20 is fixed to the rim 12 through the round fox-shaped tire groove U. . The upper wall 12, the lower wall 13 and the side wall 14 are made of carbon fiber raw materials. During the manufacturing process, 'inflation through the tube is reduced, carbon fiber raw material particles filled in a mold towel are heated and pressed to form a rim. The shape becomes a solid configuration with a certain hardness. During the manufacturing process, the inflated nylon tube is packed at the center of the rim pumping, so the fine-shaft-centerline structure. This product is built into the mold before the molding, and the nylon tubes are stacked vertically. When heated and pressurized, the gap between the nylon tubes allows carbon fiber raw materials to enter, and it will be formed after molding. According to San_17, the spine supports the niches loosely between the two side walls 14 and separates the original single-hollow space into two upper and lower hollow spaces.本 _ 之 敎 # 壁 17, _ 边 _ 之 韵 维 蝶; The same product made with the rim 10-is a body-shaped finished product, without the need for subsequent extra joining steps, which can reduce the time and cost of the manufacturing process. In addition, the horizontal support wall 17 of this implementation, because it is about _1G about H i4, and the upper and lower walls of the rim are longer, can strengthen the horizontal stress, and because the horizontal support is' more suitable for the body. It will be too heavy, or it will have a smaller impact force than M268199. Please refer to the third figure for the second embodiment of this creation. In this embodiment, the rim is made as described above, but the two nylon tubes placed during the molding are arranged side by side, so that After forming the rim, a vertical support wall π is formed perpendicular to the space between the upper wall 12 and the lower wall 13. Since the longitudinal support wall 18 is supported by the upper wall 12 and the lower wall 13, it has a stronger support effect for impact from top to bottom. Therefore, the longitudinal support wall 18 of this embodiment can strengthen the vertical stress for the longer inner rim of the rim side wall, and because of the vertical support, it is more suitable for the heavier body or the impact force when traveling. Vehicles. For the third embodiment of this creation, please refer to the fourth figure. In this embodiment, the production of the rim is also as described in the first embodiment, but when it is formed, four nylon officials are placed. After the rims are formed, a cross-shaped support wall 19 is formed which is perpendicular to the upper wall 12, the lower wall 13 and the two side walls 14 at the same time. The cross supporting wall 19 strengthens both the vertical and horizontal directions. Qian Weiyun's touch wire is the best, and it is suitable for vehicles with more collision opportunities and a larger impact force. Because the carbon fiber has not recovered its elasticity after hardening and molding, when the carbon fiber is impacted or smashed, it is easy to cause cracks, cracks, increase the support of this creation, and greatly improve the structure of the towel line, but there is a cushion. The body's cushioning also hinders the fiber rims from being stronger. Therefore, in the creation, when adding the shape, the epoxy is added to the _like material f, so that it is formed below 12-the layer is closely attached to the first-the buffer body 15 and the bottom Above the wall ^ M268199, a second buffer body 16 is formed close to the lower wall. The undertaker above the first buffer body 15 is due to the stress generated when the tire contacts the ground, especially when the tire falls from the leap state, in cooperation with the support wall, it can support and buffer the generated impact force without As a result, the tire between the upper wall of the rim and the side wall is broken due to the squeezing of the tire. The second buffer body of the New Zealand has 16 positions and supports the supporting force transmitted from the wheel axle to buffer the stress generated by the lower wall 13 and the spoke to protect the structure between the lower wall of the rim and the side wall.
