DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a bicycle frame vehicle, and more particularly to a bicycle frame vehicle having a rib inside. [Prior Art] For the bicycle body structure that is in operation, the stress on the connection portion of the two vehicle tubes is higher than that in other parts of the vehicle body, so as shown in Fig. 1, it is conventional. The connecting portion 12 of the second pipe 1 needs to be structurally reinforced. The method of structural reinforcement is usually to weld the reinforcing sheet 3 to the outer wall of the connecting portion 12, whereby the connecting portion 12 is less likely to be deformed or broken by stress. ▲Because the reinforcing sheet 3 must be manufactured separately, it will cause the manufacturing cost to be raised. = The reinforcing sheet 3 is welded to the connecting portion η of the vehicle body, and a procedure must be added for the manufacture of such a reinforcing body, and the construction quality thereof is also The ultimate reinforcement quality is not an absolute improvement; the other is now! The driving design is focused on light weight and high strength (increasing the rigidity of the car body - the complete bicycle body usually has multiple needs to reinforce The 4! 2, if the reinforcing sheet 3 is installed in each of the connecting portions 12, the overall weight will increase, so that the overall rigidity/weight ratio cannot be significantly improved: outside, as shown in FIG. The industry has also developed another conventional bicycle type vehicle tube 7 having a traverse (four) rib 7 traverses the vehicle tube 7; and adding the strength (ride/weight ratio) of the vehicle tube 7, such as: 1: The method of attacking and strengthening is more effective in raising the butterfly than 'but the extent of its improvement is not quite significant, and there is still room for improvement 5 200904695. As shown in Figures 3 and 4, a loan is revealed in the country. Patent 唬 No. 230953, the second help one car to be noted, but, the product, - half "also = r::=8r causes the tapered portions 82彳&Q^ of the ribs 80 to closely abut each other to cause the disappearance of the gap at the center of the vehicle officer 8, and the finished product of the vehicle tube 8 is as shown in the figure bucket It is still of the same kind as the above-described vehicle tube 7 having the traverse ribs 7〇, and has the problem that the (four) sex/weight ratio cannot be effectively raised upwards. [Invention] Therefore, the object of the present invention is to provide a A bicycle frame tube that improves the rigidity/weight ratio (strength) of the overall frame without the use of a reinforcing sheet. The bicycle frame tube having a rib inside the inside of the rabbit body includes a hollow tube and at least a rib extending from the inner wall of the hollow tube toward the center of the hollow tube, and only one end edge of the rib is connected to the inner wall of the hollow tube.

As shown in FIG. 12, and with reference to FIG. 5, a sixth preferred embodiment of the present invention is for fabricating the above-mentioned seat post 48, including a hollow tube 5, and two lateral walls formed on the inner wall of the W tube 5. The rib 6 increases the lateral rigidity and strength and a longitudinal rib 6 at the grip ring holding point thereof to increase the resistance strength of the yoke bundle % 431. The ribs 6 each extend toward the center of the hollow tube $ and each of the ribs 6 has only one end edge connected to the inner wall of the hollow tube 5. 200904695 The above hollow tube 5 is made of a material selected from the group consisting of carbon fiber, Kevlar fiber, Basalt fiber, glass fiber and a combination thereof, or magnesium. Low-specific gravity metals such as alloys, aluminum alloys, aluminum-magnesium alloys, aluminum-niobium alloys, and titanium alloys are not limited herein. The material of the above-mentioned rib 6 can be made of the same material as that of the hollow tube 5, but it can also be different due to design considerations, and is not limited thereto. The arrangement position and length of each of the ribs 6 (also the distance extended from the inner wall of the hollow tube) are subjected to stress analysis, and are set according to the stress state and the force direction of the vehicle body, but The length and configuration position may also differ from the disclosed position and length due to different design considerations. Referring to Appendix 1, the applicant is directed to a hollow tube having a non-transverse rib according to the present invention, a hollow tube having a transverse rib, and another hollow tube having no ribs. The stress analysis diagram nhai·# stress analysis diagram represents the stress experienced by the corresponding hollow tube 5 under various specific forces, and can be used to calculate its relative rigidity (underformation rate). The design spindles in the above embodiments are all in the vicinity of the connection port of the vehicle pipe, and the strength (weight/weight ratio). Please refer to the attached part 2, and the stress analysis chart shown in the accessory i is used. It can be calculated that the hollow tube 5 having the non-transverse rib 6 of the present invention has a higher rigidity/weight ratio than the conventional hollow tube 2 having a transverse rib and another conventional hollow tube having no rib. The higher rigidity/weight ratio is higher in strength, and thereby successfully improves the shortcomings of the conventional body, such as the conventional body, which requires the addition of the reinforcing sheet, thereby simplifying the production process and reducing the manufacturing cost of the system. , In the bicycle frame tube having the rib 6 inside, the stress state is used to analyze the stress state and the direction of the force of the vehicle body, and the non-traverse rib 6 is disposed on the inner wall of the hollow tube 5 constituting the vehicle body, not only Effectively increasing the rigidity/weight ratio can also simplify the manufacturing process and reduce the manufacturing cost, so that the object of the present invention can be achieved. However, the above description is only a preferred embodiment of the present invention, and cannot be limited thereto. The scope of the present invention, that is, the simple (four) effect changes and modifications made by the scope of the patent and the description of the invention in the present invention are still within the scope of the patent of the present invention.
