Definitions
- the present invention relates to bicycle frames, and more particularly to a fiber composite frame. Background technique
- the traditional bicycle frame is mostly made of aluminum alloy, which is structurally strong but heavy.
- Today's bicycles are becoming lighter and lighter, so many bicycle frames are made of carbon fiber composites that are hard and have a lower specific gravity than aluminum alloys.
- the foregoing carbon fiber composite material frame is manufactured by coating a carbon fiber composite material on an outer surface of an inflatable member, and after the frame is formed, the gas in the inflatable member is removed, and then the air-inflated inflatable member is self-contained.
- the manufacturing process is quite cumbersome.
- the frame is formed by connecting a plurality of tubes, and if the plurality of interconnected tubes are integrally formed by the above manufacturing method, the manufacturing is performed. more difficult.
- the aforementioned inflatable member is slightly soft even if it is filled with gas, so that the carbon fiber composite material is practically difficult to cover the inflatable member relatively densely.
- the carbon fiber composite frame is hollow, if the thickness is too small, it is relatively easy to be broken, and if the thickness is increased, the purpose of weight reduction cannot be achieved. Summary of the invention
- the single frame unit can be made into the shape of the frame, or can be connected to the frame by a plurality of frame units.
- there is no conventional procedure for degassing and removing the inflatable member in the manufacturing process of the fiber composite frame so that it is easier to manufacture, and each foam is harder than the conventional inflatable member, so the fiber composite material It is easier to be densely coated on each foam.
- the fiber composite frame can have a relatively thin fibrous composite outer layer, and can also be formed by the buffering action of the foams and the structural beam structure formed when the outer layers of the fiber composites of the two members are joined together. It has the characteristics of being difficult to break, and has the advantage of being relatively light in weight.
- FIG. 1 is a schematic view of a bicycle having a fiber composite frame provided by a first preferred embodiment of the present invention
- FIG. 2 is an exploded perspective view showing a portion of the fiber provided by the first preferred embodiment of the present invention.
- Composite frame Figure 3 is a cross-sectional view of Figure 1 taken along line 3-3;
- Figure 4 is an exploded perspective view showing a fiber composite material frame according to a second preferred embodiment of the present invention
- Figure 5 is a perspective assembled view of Figure 4, and wherein the fiber composite material frame is composited A portion of the outer layer of material is removed for illustration;
- Figure 6 is a cross-sectional view taken along line 6-6 of Figure 5;
- Figure 7 is a cross-sectional view taken along line 7-7 of Figure 6;
- Figure 8 is a cross-sectional view taken along line 8-8 of Figure 5;
- Figure 9 is a cross-sectional view taken along line 9-9 of Figure 5. Detailed ways
- a fiber composite frame 10 according to a first preferred embodiment of the present invention includes a frame unit 11 including a four-bar body 12 which is like a conventional bicycle.
- the front tube, the upper tube, the lower tube and the seat tube of the frame are connected to each other in a closed quadrilateral shape.
- the frame unit 11 includes two members 20 , and each of the rods 12 is connected by the two members 20 .
- the shapes of the members 20 are closed like the frame unit 11 .
- Quadrilateral, only Figure 2 shows only the section of the two members 20 in the body 12 for illustration.
- each of the rod bodies 12 has a cylindrical shape, and thus the respective members 20 are formed by connecting four semi-cylindrical bodies, but are not limited thereto.
- Each member 20 has a foam body 30, and a fiber composite outer layer 40 coated on the outside of the foam body 30, and the fiber composite material outer layer 40 has a joint surface 42.
- the foam 30 is made of a foamed material such as polyurea ester
- the outer layer 40 of the fiber composite material is made of a composite material such as carbon fiber, glass fiber or other polyester fiber, and has characteristics such as hardness, small specific gravity, high temperature resistance and corrosion resistance.
- carbon fiber is taken as an illustrative example.
- the two members 20 are fixed to each other by the pressing surface 42 of the fiber composite outer layer 40 by heat pressing, and the shapes of the two members 20 are substantially symmetrical with each other centering on the joint of the two members 20.
- the frame 10 is not only relatively light in weight, but by the arrangement of the foam 30, the frame 10 as a whole has a solid structure, and even if the outer layer 40 of the fiber composite material is relatively thin, it can be foamed. Buffering effect of body 30, and the second The fiber composite outer layer 40 of the member 20 joins the forming beam structure such that the frame 10 has a property of being less susceptible to breakage.
- the fiber composite material frame 10 in the manufacturing process of the fiber composite material frame 10, there is no conventional procedure for degassing and taking out the inflatable member, and thus the fiber composite material frame 10 is relatively easy to manufacture.
- each of the foams 30 is harder than the conventional inflatable members, so that the fiber composite material is more easily densely coated on the respective foams 30.
- the fiber composite frame provided by the present invention may also include a plurality of frame units, for example, including four vehicles respectively forming the rods 12.
- the frame unit that is, the invention can also divide the frame into a plurality of frame units, and each frame unit is first formed by connecting two members made of a foam and an outer layer of a fiber composite material, and then, each frame The unit is further joined to the outer frame of the fiber composite material of the other frame unit by means of hot pressing, and then connected to the outer frame of the fiber composite material of the other frame unit.
- the invention divides the single frame unit into two symmetrical members, so that the design can not only produce the beam structure as described above, but also make the fiber composite frame more rigid and can be foamed.
- the procedure for coating fiber composites in vitro is easier and less time consuming.
- a second preferred embodiment of the present invention further provides another fiber composite frame 50 that differs from the fiber composite frame 10 described above in that the components of the frame 50 are
- the foam 70 of 60 has a plurality of grooves 71, 72 intersecting in a grid shape, including a plurality of longitudinal grooves 71 extending substantially longitudinally of the rod 12, and a plurality of intersecting longitudinal grooves 71 and surrounding the An annular groove 72 of the foam 70.
- each of the annular grooves 72 is substantially perpendicular to the longitudinal direction of the shaft 12 (ie, perpendicular to the longitudinal grooves 71), but is not limited thereto; and the foam 70 may only be There are longitudinal grooves 71 or only annular grooves 72.
- each member 60 When the fiber composite outer layer 80 of each member 60 is coated on the foam 70, a part of the fiber composite outer layer 80 is filled in the grooves 71 and 72 of the foam 70 to form reinforcing ribs 82.
- This not only makes the structural strength of the frame 50 better, but also makes the fiber composite outer layer 80 and the foam 70 better.
- the number and type of the grooves 71, 72 and the reinforcing ribs 82 of the respective members 60 are not limited to those provided in the present embodiment, as long as the foam 70 is provided with a groove into which the outer layer 80 of the fiber composite material is filled.
- the trough can achieve the efficacy as described above.
