Description of the invention (/) A7 B7 The Central Bureau of Economic Affairs of the Ministry of Economic Affairs Beigong Consumer Cooperative Society printed the cover. The present invention relates to a composite bicycle rack with an integrated Y-shaped round tube structure. The lower tube and the seat tube are independently supported by the conventional method into a unique structure that is combined with a fork and a fulcrum to form a "Y" shape; the invention also relates to a method for manufacturing the aforementioned bicycle frame structure. Qiaotong drills the bicycle frame, whether it is a metal frame, a carbon fiber joint frame or a Hengfei fiber frame, its shape is nothing more than eight independent round tubes that are welded, glued and hardened into a front corner and a rear triangle The structure of the "head tube" is to connect the handlebar and the J wheel mechanism. "The seat tube" connects the seat cushion perpendicular to the pedal axis, and the "upper tube" connects the head tube and the upper edge of the seat, and the "down tube" Connect the lower edge of the head tube and the seat tube. These tubes combine to form the front triangle of the frame. The second upper fork supports the upper edge of the seat tube and the rear wheel supporter of the rear axle. And the rear wheel axle rear wheel supporter, these tubes are combined to form the rear triangle of the frame. The traditional diamond frame such as metal frame, carbon fiber joint frame or integrally formed frame has many joints, so it requires complicated welding or gluing hand combination, and these joints must bear the frame riding The various problems caused by the time-lapse cause a variety of structural problems. In addition, the frame is also combined with the same-size car tube joining technology, joining quality control and complicated processing procedures. The ancient-style single-thin shell carbon fiber frame is formed by a plate-shaped thin outer plate combined with strong 2 ribs and other structural elements, such as US Patent No. 4,5 丨 3,986, or the inner surface is sandwiched by a flat outer plate The core material, after joining, forms a three-layer laminate type US Patent No. 4,23g, No. 332. In addition, the pre-layered tubular material = connected to the formed bicycle frame, such as the US Patent No. 4,479,662 shell frame has-disadvantages, that is, each structural element must be joined, but the pre-molding of each structural element, stacking angle considerations , Overlap method, patch foot stand repair and hardening, so it is not only time-consuming in manufacturing but also high in cost. The vertical tank, stone frame and single thin shell frame are slightly compensated for vertical rigidity due to the torsional rigidity and lateral roughness. In other words, it adds torsion and lateral mandrels, and it also greatly improves vertical rigidity. In this way, the riding efficiency of the bicycle can be made too large. The charisma is too large and the shock absorption capacity of the frame is lost. During the secret riding; the driving control and riding comfort of the driving cause adverse effects on its rigidity and rigidity.

Description of the invention (2) All 4th-year-olds have taken their jobs in Ji Ketan. The balance of this element is to overcome the above problems and develop easy-to-manufacture manufacturing with high cost (comfortable According to the above purpose, the present invention provides-the hollow tube is combined with the traditional wrong-stone frame. The upper tube, the lower tube and the seat tube are connected to the tube in the proper position of the front half of the frame. The hollow round tube in the pedal shaft sleeve and hollow connector is "oblique, +3 is connected to the head tube sleeve and the hollow connector hollow tube ^ 2" ".

The secret of the present invention-manufacturing this-compound bicycle is a gift. The main pipe consists of a single-hollow and three-way connection of the end of the pipe and the fork and the branch, which will obtain the coordination of 4f rigidity and torsional rigidity. , In this way, the shovel of the bicycle frame can be improved. The above-mentioned traditional diamond-shaped frame or single-thin composite frame does not have a compensation function. The body-shaped composite material of the γ-shaped round tube structure of the present invention will provide the maximum vertical rigidity compensation, and also The lateral bending and torsional rigidity of the frame are improved. In addition, the rider of the traditional diamond-shaped frame directly feels the vibration transmitted by the seat tube. This vibration is caused by the movement of the front and rear wheels and the pedal. This Ύ " type structure will greatly improve the shock absorption capacity to increase the riding The comfort of the person. ^ The body-molded composite bicycle frame of the invention is a uniform-tubular structure, and the joints of its various parts are lapped with the composite materials in a so-called, integral joint, to form a solid joint. The "integral joint" method One or more layers of unhardened prepreg fibers are overlapped and contacted with another layer of uncured prepreg fibers, and then hardened to form; and the overlapping part ^ "size (length) can be 25rnm according to actual needs. 501 varies. Due to processing requirements, there may be different ways of forming and joining the various parts of the frame; the following defines four different joining methods: "Mo joint, is an unhardened component or segment, and an unhardened component

Description of the invention (3) The body joint is in-^ ;, and the film joint is "unhardened component or joint piece or field piece or integral joint in the molding process", together; ,, Die-bonding " membrane bonding " to join the components and / or segments together; "bonding " is the luxury of the hardened meaning that each joint or component is hardened and joined together-another influence car The dimension of the direction of the dimension. Fibers that are parallel or oblique to the direction of the tube axis, and the sigh meter will provide the best vertical rigidity compensation and lateral and torsional rigidity. Ages i air thin tube structure-body forming composite bicycle The material used for the frame is preferably a continuous square and a moldable synthetic material. This synthetic resin can be a mixture of ring two, two thermal decomposition hardener, because this part belongs to the conventional technology Repeat. This-the prepreg that reinforces fiber and synthetic resin is the so-called, wide ^ ', bucket This reinforced continuous fiber can be woven or non-woven fiber, but single fiber is better. Single-directional fiber is the best physical property, and it can be designed to extend from ί 官 -f to the other end. When using prepreg materials, the layers need to be overlapped in a grid to form a solid continuum. It is suspected that the type and type of prepreg materials used are also not very different. , Compressive strength, tensile strength, shock absorption capacity and weight, the selected fiber includes glass fiber, carbon fiber, Kevlar fiber or quality n fiber type and can be low, medium and high modulus. If there is a special Ϊ lose = Cleverly divided into i75, 5G or 25 weight specific fiber. In addition, there are also ancient; its moxa frame g is lined with glass fiber for insulation with metal. Sometimes it is similar to the strength of the car's tube direction. Use a single direction of glass fiber in the outer layer vertically and axially. To the wrong way, the Zhilonghe bicycle frame provides many advantages. In the part of the front frame, the original diamond-shaped frame is upper, lower and tube. The I-shaped structure; the rear frame part discards the fork on the original diamond-shaped frame Bottom left—right single branch support #rear wheel supporter, not only simplifies the frame and improves its robustness and reduces the weight of the frame. In addition, the lack of upper tube t structure can avoid the rider ’s span Injury from sitting. The beam-shaped yoke of γ-tube has a wind resistance design of Wei.

Depending on the part of the patch, the width of the patch used has different widths, the best is Qiao ~ 80 =. In order to achieve a smoother surface, the patch patch does not need to overlap, but the edge overlap method is adopted. Regardless of whether it is a spiral method or a parallel axis, it is best to use a single fiber direction to continuously cover the tube from one end to the other end. The rotating tube parts are pre-formed by covering the mandrel with the day layer, and the number of layers is determined according to the required functional characteristics and the required thickness of each tube part; for example, 8 layers of general pre- / hardened materials Can produce approximately; 1.5mm wall thickness. The lamination angle of each frame tube relative to the tube axis is one of the important factors affecting its functional characteristics. The whole frame has about 1 ~ the best is 丨 〇. ~ 45. (The best is 25.) Angle ^ Stack f. For the upper and lower fork branches, it is better to increase the lamination angle. If the spiral winding method is used, the angle can reach 70. . The design of these fiber angles can improve the strength of these pipe fittings, can withstand the bending and torsional stress, and increase the shock absorption effect, making the rider more comfortable. If spirally wound with 25. Wrapped from one end of the tube to the other end, the lamination angle with a difference of 130 ° from 25 ° is wound back. , The main pipe (26), the upper inclined pipe (24), the lower inclined pipe (25), the upper branch (22) and the lower fork branch (23) can be hardened separately, and then use various connectors (referring to the head pipe connector ( 31), seat tube connector (32), BB connector (33), hollow connector (30), upper fork branch connector (35), lower fork branch connector (34), etc.) and patch are connected in together. Because the manufacturing, hardening, and forming techniques of individual components are conventional, they will not be repeated here. The prepreg material stack of each tube of the frame has fibers arranged in one direction, preferably extending from one end of the tube to the other. However, due to the three-dimensional shape, it is inevitable to use staple fiber, but its length is preferably 90% more than 100mm (150_ is better, 300mm is the best). In order to allow the molded product to have an overall stress distribution, the overlap overlap size of the prepreg is 25 mm, and 50 mm is better. Referring again to FIG. 16, it is a thin frame of an unhardened frame that has been assembled. In this hollow hollow shell of the frame, an air blowing bag is arranged to extend from the upper inclined pipe (24) to the main pipe (26), the lower inclined pipe (25) and each hollow connector. In order to apply pressure uniformly to all parts, use a single branch type air bag or multiple air bags placed in some thin shells of hollow frames. After putting this thin hollow shell of the frame into the mold, the thin shell is pressed against the cavity wall by heating and hardening to form (this is the above-mentioned "Mo Mo" method, and for the familiar Skilled person and -11.

For the upper and lower supports (22) and the lower and second supports (23), a solid foam material can also be used for the pressurized material, and this foam material can be a foamed resin. The upper and lower supports (22) and the lower and second supports (23) can also be preformed by using a blower bag under pressure; after the pre-formed hollow upper support and lower fork support thin shells are placed in the blower bag, put them in In each mold cavity, it is blown, pressurized, heated and hardened. After hardening, the upper fork branch (22) and the lower branch (23) are placed in the mold cavity in Figure 16 and the upper inclined tube (24) and the lower inclined tube (25) are respectively seated in the seat tube connector (32) And the BB connector (33) is overlapped with the front frame, which is heated and hardened. When the frame is hardened, the frame is taken out of the mold cavity, the air blowing bag can be pulled out, and the foam can be dissolved out with a solvent. However, due to the small volume and light weight of the air blowing bag or the foam material, it can be left in the frame without having to be taken out. Moreover, the use of certain foam materials (rigidf〇am) foam material itself has strength, so it can reduce the prepreg material The number of stacked layers can be reduced, and the thickness of the thin shell can be reduced by about 30%. The prepreg material selected here is about 12 (Tc hardened is better. The foam material can contain a hard non-hard Expanded resin foam, and then wrap a composite material with a thin thermal expansion adhesive. The heating foam adhesive, the curing temperature is also preferably 20.0. As mentioned above, when pre-forming each connector , The metal sleeve and the rear wheel supporter ⑵ '2〇 are embedded and wrapped in the prepreg. At the same time, some other caravans in other car camps must It must be embedded in the prepreg so that it can be hardened and fixed together-fixed, and it will be used for the assembly of the hardware equipment outside the frame. The equipment includes brake lines, gear shifts and other fixed seats.
