Abstract

The utility model provides a novel carbon fiber vehicle frame structure, comprising an upper tube and a lower tube; a stop bolt and a wiring tube are arranged in the vehicle frame tube body and integrally molded with the tube body; and the tube wall connected with the stop bolt and the wiring tube is a sunken arc surface. As the stop bolt and the wiring tube are molded in the sunken arc surface of the carbon fiber vehicle frame tube wall, the stop bolt and the wiring tube are not exposed or partially exposed, so that the bike looks simple and smooth. As the stop bolt is integrally molded with the vehicle frame, the entire vehicle frame looks simple and beautiful. Furthermore, the stop bolt integrally molded with the vehicle frame helps to reduce the follow-up machining, reduce the overall weight of the frame and also simplify the production process.

Description

A kind of later-model carbon fiber bicycle frame structure

Technical field

The utility model relates to the bicycle field that carbon fibre material is made, and relates in particular to a kind of later-model carbon fiber bicycle frame structure.

Background technology

Bicycle is a kind of as outdoor exercises, with running, walking, the same effect with endurance and raising cardio-pulmonary function of exercise internal organs of swimming.Bicycle is not only the important vehicle, also is a kind of equipment of body-building simultaneously.In the U.S. 20,000,000 people body-building is by bike arranged; In Europe by bike " one-day tour " also become one of the most fashionable fashion mode of motion.For bicycle, sports bicycle particularly, customer's requirement only not only is present in its speed, and safety waits aspect of performance, and the requirement of its overall appearance is also improved gradually.

Usually, all can be provided with several on the vehicle frame of carbon fiber bicycle and end bolt, the brake cable of bicycle, what middle shift cable and back shift cable all can be on vehicle frames ends bolt and mistake, and it is regional and go to lead to different affiliated runnings again; Because of vehicle frame is made up of pipe or oval tube, it all is after the vehicle frame moulding that the only bolt of carbon fiber bicycle closes, after finishing, application carries out, so all end bolt and line all can highlight, expose outside. like this from the single-piece outward appearance, seem complicated and attractive in appearance not to the utmost., and processing ends bolt afterwards, weaken the aesthetics of vehicle frame, and increased bicycle single-piece weight.

The utility model content

Creation purpose of the present utility model provides a kind of later-model carbon fiber bicycle frame structure, and it will end bolt and each line body is hidden in the body of vehicle frame as much as possible, allow bicycle outward appearance smoothness succinctly, not at random; And end bolt, the spool following process that do not need simple in structure.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of later-model carbon fiber bicycle frame structure, comprise top tube and down tube, and the vehicle frame body is provided with integrated with it bolt and the spool of ending, and ends the tube wall that bolt links to each other with spool and is the recessed cambered surface of introversion.

Described spool is arranged on wall body inboard, pipe bottom, and one-body molded with last pipe, and the port of spool exposes to tube outer surface.

Described only bolt is by the wall body of managing the bottom indent down, and the court of a feudal ruler, both sides is stretched and formed arcuation block formation to the left and right, and this arcuation block is provided with pilot hole.

After adopting said structure, all be molded in the cancave cambered surface of carbon fiber bicycle frame tube wall with spool, therefore end bolt and spool and be not revealed in appearance, or partly expose owing to end bolt, allow like this bicycle outward appearance smoothness succinctly, not at random.And bolt and vehicle frame are one-body molded owing to ending, thereby make the overall appearance of vehicle frame more succinct, have beautified moulding; Moreover, with the one-body molded bolt that ends of vehicle frame, reduced machinework afterwards, alleviated the overall weight of vehicle frame, also simplified production process simultaneously.Bicycle oil pipe brake cable, middle shift cable and back line body such as shift cable can be introduced in by the port of spool in the spool, because spool is arranged on vehicle frame tube wall inboard, so these line bodies are hidden in the vehicle frame pipe, outside face is neatly not mixed and disorderly; Because spool internal diameter and line body match, the line body is difficult for rocking in body and produces noise in use, and be convenient to the line body and introduce and draw because the two-port of spool is located at the surface of vehicle frame body, spool can play guiding when penetrating because of the line body, is convenient to assembly operation.

Below in conjunction with drawings and Examples the utility model is described in further detail; But a kind of later-model carbon fiber bicycle frame structure of the present utility model is not limited to embodiment.

Description of drawings

Fig. 1 is the later-model structural representation of this reality;

Fig. 2 is that the A of Fig. 1 is to diagrammatic sketch;

Fig. 3 is the B-B cutaway view Amplified image of Fig. 1;

Fig. 4 is the C-C cutaway view Amplified image of Fig. 1.

The specific embodiment

As shown in Figure 1, a kind of later-model carbon fiber bicycle frame structure of the utility model, the bottom of top tube 1 is provided with the cambered surface 10 that concaves, as Fig. 2, shown in Figure 3, spool 12 is positioned at the cavity of pipe, and one-body molded with cambered surface 10, and the two-port 120 of spool 12 exposes to pipe 1 outside face.Manage in 1 tube wall on the carbon fiber bicycle frame because spool 12 is molded over, its two-port 120 outer outside faces that are exposed at pipe 1, and go up pipe 1 wall body that links to each other with spool 12 is the cambered surface 10 that concaves, therefore when numerous bicycle line bodies 3 pass spool 12, all be hidden in pipe 1 body, guide different affiliated areas into by port one 20 again.Allow like this bicycle outward appearance smoothness succinctly, not at random.And spool internal diameter and line body match, the line body is difficult for rocking in body and produces noise in use, and be convenient to the line body and introduce and draw because the two-port of spool is located at the surface of vehicle frame body, spool can play guiding when penetrating because of the line body, is convenient to assembly operation.

As shown in Figure 4, under manage 2 and be provided with only bolt 20, ending bolt 20 is by the wall body of managing 1 bottom indent down, the court of a feudal ruler, both sides is stretched and is formed arcuation block formation to the left and right, this arcuation block is provided with pilot hole 201, pass for each the line body on the bicycle owing to be the cambered surface of indent with ending the following tube wall that bolt links to each other, therefore only bolt according to the degree of depth or all or part of being hidden in down in the pipe of cancave cambered surface.

Structure is ended bolt and spool and is molded in the inner concave arc surface of tube wall on the carbon fiber bicycle frame as can be known thus, therefore end bolt and spool and be not revealed in appearance, or part exposes, allow like this bicycle outward appearance smoothness succinctly, not at random.And bolt and vehicle frame are one-body molded owing to ending, thereby make the overall appearance of vehicle frame more succinct, have beautified moulding; Moreover, with the one-body molded bolt that ends of vehicle frame, reduced machinework afterwards, alleviated the overall weight of vehicle frame, also simplified production process simultaneously.Bicycle oil pipe brake cable, middle shift cable and back line body such as shift cable can be introduced in by the port of spool in the spool, because spool is arranged on vehicle frame tube wall inboard, so these line bodies are hidden in the vehicle frame pipe, outside face is neatly not mixed and disorderly.

The above, it only is the utility model preferred embodiment, be not to limit the utility model practical range with this, all personages who is familiar with this technology, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
