The force of stepping on the bicycle causes the transmission efficiency of the bicycle to decrease. If the rider is added with the weight of the five-way part, the amount of the repairing force is increased, so that the circumference of the five-way part is thickened, and the weight of the bicycle frame is added, so that the ride is allowed. The passenger is more laborious. Therefore, how to balance the f-mount of the frame with the five-way 敎 structural joints is a research and development project that the industry has turned to. [New content] 3 In order to achieve the above objectives, the bicycle frame of this creation is made of fiber-reinforced material, which includes a five-way part, a riser's lower tube, two rear lower forks, And at least one rib. The riser extends upwardly from the five-way portion, the lower tube extends forwardly from the five-way portion, and the two lower and lower tubes extend backward from the five-way portion, the five-way portion having a wall The circumference of the wall is emptied to the left and right sides of the peripheral wall, respectively, and a circular tube portion is provided to connect the empty chamber to the outside. The rib is extended from the junction of the riser and the lower officer toward the two round pipe portions, or the rib plate extends from the junction of the riser pipe and the second rear fork pipe toward the two round pipe portions Out. [Embodiment] In order to better understand the features of the present invention, the preferred embodiments are described below with reference to the drawings, in which: the first drawing is a front view of the first preferred embodiment of the present invention; A partial perspective view of the first preferred embodiment is created; the second drawing is a partial cross-sectional view of the first preferred embodiment of the present invention; the fourth drawing is a schematic view of the second preferred embodiment of the present creation; A schematic view of a preferred embodiment; and a sixth diagram is a schematic view of a fourth preferred embodiment of the present invention. »Monthly referring to the first to second figures, the bicycle reinforced frame 1G' of the first preferred embodiment of the present invention is made of a fiber reinforced material such as fiber reinforced resin, which is made of carbon fiber. Actually, it is also possible to use (four) age, face age or Kevlar fiber, which may be a thermosetting resin or a thermoplastic resin. M429641 The reinforced frame ίο includes a one-piece five-part bracket, a riser 22, a lower tube 24, two lower fork tubes 26, and two ribs 28. The riser 22 extends upwardly from the five-port portion 2, and the lower tube 24 extends forwardly from the five-way portion 20, and the two lower-lower tubes 26 extend rearwardly from the five-way portion 20. The five-way portion 2 has a peripheral wall 2〇2, and the peripheral wall 202 defines an empty chamber 2〇4. The left and right sides of the peripheral wall 2〇2 are respectively provided with a circular tube portion 206, so that the empty chamber 2〇4 and The outer tube portion 206 protrudes inwardly into the empty chamber 2〇4, and each of the round tube portions 2〇6 is correspondingly provided for one day of mandrel (not shown). One of the ribs 28 extends from the junction of the official 22 and the lower tube 24 toward the two circular tube portions 2〇6 and is connected to the two circular tube portions, and the other rib plate 28 is The junction of the riser 22 and the second lower tube 26 extends toward the two round tube portions 2〇6 and is connected to the two round tube portions 206. It can be understood that the reinforcing frame 1 can be used as needed. Only one of the ribs 28 is provided. The two ribs 28 increase the weight of the frame 10, but can be greatly increased by φ, and the structural strength or rigidity of the five-way portion 20 not only makes the five-way portion 20 can bear a large stress but is not prone to occur. The structure is broken, and the bicycle is able to improve the bicycle without being worn out by the rider. Based on the spirit of the present invention, the structure of the frame 1 can be varied. The second preferred embodiment of the present invention is shown in the fourth figure, compared to the above-described k-th preferred embodiment. The frame system further includes a bridge portion 3〇, the bridge yarn 30 is connected to the end of the two ribs 28 at its three ends, and the lower/lower side is connected with the two round pipe portions 206, and the bridge portion 30 is also The two ends of the 5 M429641 can be connected to any position of the corresponding side of each of the ribs 28. The bridge portion 30 can further increase the structural strength or rigidity of the five-way portion 2〇. Further, the reinforced frame of the present invention may have a plurality of bridge portions, each of which is connected to the two ribs 28 (not shown) by their two ends side by side. A third preferred embodiment of the present invention is shown in the fifth figure. The reinforced frame of the present embodiment includes a two-ribbed panel 32, and one of the ribs 32 is bounded by the symmetry 22 and the lower tube 24. The lower portion is not connected to the two round pipe portion 206, and the other rib 32 extends downward from the boundary between the riser 22 and the second rear fork pipe 26 without being connected to the two round pipe portions 2〇6. . In fact, the reinforced frame of the present invention can be provided with only its ribs 32 as needed. A fourth preferred embodiment of the present invention is shown in the sixth embodiment. In contrast to the third preferred embodiment described above, the reinforced frame of the present embodiment further includes a bridge f portion 34, the bridge portion 34 being The two ends are connected to the ends of the two ribs 32. However, the bridge portions 34 may be connected at any two ends to opposite sides of the ribs 32 to increase the structural strength or rigidity of the five-way portion 3G. The above embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the present invention. Those skilled in the art can modify or substitute the present invention based on the spirit of the present invention. Within the scope of this creation. 6 M429641 [Brief Description of the Drawings] The first drawing is a front view of the first preferred embodiment of the present invention; the second drawing is a partial perspective view of the first preferred embodiment of the present creation; 4 is a schematic view of a second preferred embodiment of the present invention; a fifth diagram is a schematic view of a third preferred embodiment of the present invention; and a sixth embodiment is a fourth preferred embodiment of the present creation schematic diagram.
