Abstract
The bicycle frame made of carbon fibre composite features tachnically iso-strength design, integral shaping, different thickness for different position, use of expansion film and foam plastics as filler, preembedded metalic connecting parts, bigger arc transition, smooth surface, light weigh (only 1.5 kg), high fatigure strength (500 thousands times under 2g overload), and high energy absorption power (70J).
Description
The present invention relates to a bicycle rack, particularly the carbon fiber composite structure bicycle rack.
Present popular bicycle rack, polyphyly metal welding fitting structure, weight is big, and fatigue resistance is poor, and energy absorbing is low, and owing to adopt the typing Metal Material Welding, can't form comparatively ideal appearance.
Purpose of the present invention, be to release a kind of carbon fiber composite structure bicycle rack according to equal strength principle and the formation of monolithic molding technology, after the steel and light-alloy structure of China's bicycle rack, increase new varieties, to promote the development of bicycle trade technology.
Body frame structure for automotive of the present invention, realize by following proposal, promptly by preceding triangle＜11 〉, oblique fork＜12 and chain stay＜13 the whole self-propelled vehicle frame formed of three parts, each part all sticks into type with the carbon fiber composite material shop, inner in addition necessary charges, handle through chromic acid anodizing, and front fork tube＜7 of spray primer technology, central siphon＜9〉and seatpillar
＜8〉etc. attachment hardware gives and burying wherein, because the inner corner transition position is with expansion glued membrane and foamed plastic filling, and therefore outside arc transition of big garden and the smooth streamline surface of having formed.
Carbon fiber composite material bicycle rack of the present invention, compare with the vehicle frame of steel and light metal structure, have (only 1.5 kilograms in light weight, than ordinary steel light in structure 2/3rds), the fatigue resistance height is (under the big 2g overload condition, can reach 500,000 times, be better than ordinary steel structure 0.7g greatly and transship standard 100,000 times), energy absorbing (can reach 70 joules greatly, be much higher than 40 joules of ordinary steel structure), and the arc transition of big garden, smooth surface streamline have been realized in the outside, safe and reliable, be the generation new product behind the metal auto vehicle frame.
Concrete structure of the present invention is provided by following routine accompanying drawing:
Fig. 1. be the integral structure of bicycle rack.
Fig. 2. be the cutaway view of front fork tube part.
Fig. 3. be the cutaway view of seatpillar part.
Fig. 4. be the cutaway view of central siphon part.
Below in conjunction with accompanying drawing, concrete structure of the present invention is further described:
Because the inner structure of whole self-propelled car is similar substantially everywhere.Now front fork tube (Fig. 2) is illustrated with example: through chromic acid anodizing, have the high-strength superduralumin front fork tube (7) that increases anticorrosion and adhesive strength performance, by intermediate temperature setting glued membrane (4), with this metal piece and composite material strong bond.By insulating glass cloth (5) with metal piece with strengthen carbon cloth (6) and separate, in case electrochemical corrosion is metal piece, interior pipe (3) and foam block (1) are linked to be firm one.In pipe (3) be entwined by 30 ° and 0 ° of unidirectional fibre pipe, during curing, inner inflatable makes fiber press to adventitia.The polyurethane foam piece and the foamed glue (2) of filling in each corner by volume interference and blow pressure, make composite material obtain required pressure, and form smooth outside face.
The tiltedly connection of fork (12) of preceding spider (11) chain stay (13) is connected into one with J101 glue (10) in the gluing of splicing anchor clamps.Except that attachment hardware shape difference, it is similar substantially to front fork tube (7) that seatpillar (8) and central siphon (9) are located theory structure.
Claims (4)
1, a kind of bicycle rack, be made up of spider, chain stay and oblique fork, it is characterized in that it being the carbon fiber composite structure of global formation, whole fork is except that attachment hardware, all be according to the equal strength principle, based on the compound material laying adhesion coating structure of carbon fiber.
2, carbon fiber composite structure according to claim 1, the sticking shop number of plies everywhere is different with thickness.
3, carbon fiber composite structure according to claim 1, its front fork tube＜7 〉, seatpillar＜8 and central siphon＜9 etc. attachment hardware give and being embedded in wherein.
4, carbon fiber composite structure according to claim 1, the inside of its corner is with expansion glued membrane＜2〉and foamed materials＜1 filling, the outside has formed the surface of arc transition of big garden and smooth streamline.
