Abstract
The invention belongs to the field of bicycles and particularly discloses a composite frame pipe of a bicycle. The composite frame pipe comprises an outer metal layer and is characterized in that a composite hollow base pipe is sleeved in the metal layer; and a low-density foam sandwich material is arranged in the hollow base pipe. The composite frame pipe disclosed by the invention is simple in structure, reasonable in design and convenient to use; by adoption of the composite frame pipe, a light and reliable bicycle frame can be obtained and the riding safety and comfort can be improved. The composite frame pipe is suitable for wide popularization and application.
Description
(1) technical field
The invention belongs to the bicycle field, particularly a kind of composite frame tubing of bicycle.
(2) background technology
Bicycle mainly is to trample the walking-replacing tool that advances for power by manpower, compares with vehicle such as motor bike, automobiles, and is safe though the bicycle relative velocity is slower, and with the effect of taking exercises, therefore received extensive welcome.Bicycle combines to have used ergonomics, aerodynamic relative theory, and parts are numerous, like vehicle frame, crotch, handle, wheel rim, chain etc.For reducing bicycle weight, save rider's muscle power, bicycle is made by making to develop into gradually with fiber composite materials especially carbon fiber composite material with metallic material.Carbon fiber composite material is compared with metallic material, and its density only has 1.6g/m
3, be merely 1/5 of steel, therefore can reduce the bicycle deadweight greatly.In addition, carbon fiber composite material also has excellent anti-corrosion performance, strength-to-density ratio, specific modulus advantages of higher.Crotch, crank, seat pipe, handle along with the development of composite material forming and designing technique, had occurred carbon fiber composite material vehicle frame, wheel etc. again before and after the composite material component of at first making with carbon fiber composite material comprised.
Cycle frame is a tubular structure, though carbon fiber composite material has numerous advantages, it also has a big shortcoming; Promptly because the superficial hardness of composite material is lower, damage resistant not is when receiving hard thing effect of impact; Stay very dark indenture easily; Influence the whole mechanical property of vehicle frame, cause potential safety hazard, also influence outward appearance; Therefore need a kind of novel composite material vehicle frame pipe structure of design, on the basis that keeps former composite material advantage, improve the superficial hardness and the scratch resistant performance of composite frame tubing.
(3) summary of the invention
The present invention is in order to remedy the deficiency of prior art, and a kind of composite frame tubing of simple in structure, bicycle that in-use performance is good is provided.
The present invention realizes through following technical scheme:
A kind of composite frame tubing of bicycle comprises outer layer metal layer, it is characterized in that: be arranged with the composite material hollow parent tube in the said metal level, be provided with the low density foam sandwich material in the hollow parent tube.
The present invention is being arranged to the sandwich sandwich construction between hollow parent tube and the internal foam sandwich material, does the time spent receiving external load, and shear action can take place for both, further improves the rigidity of structure of vehicle frame; Parent tube outer setting metal level on the basis that keeps former tubing light weight, characteristics such as high-strength, improves the hardness on surface and the whole impact resistance of vehicle frame.
More excellent scheme of the present invention is:
Said composite material hollow parent tube is fiber reinforced composite, comprises fortifying fibre and matrix resin.
Said outer layer metal layer is aluminum alloy, titanium alloy or steel.
Said low density foam sandwich material is polyethylene, polypropylene foam, isocyanurate foam or phenol formaldehyde foam.
Said fortifying fibre is one or more in carbon fiber, fibrous glass, aramid fiber and the basalt fibre.
Said matrix resin is one or more in unsaturated polyester, epoxy resin, vinyl ester resin and the phenol resin.
The present invention can be through earlier at die for molding composite material parent tube; Make in the method that the parent tube surface forms metal level through fusion spraying, plating, electroforming or other technology then; Also can be employed in die surface and make the layer of metal layer earlier, and then the method for forming composite parent tube is made on the basis of this layer; In-to-in foam core material can pass through directly to obtain in the inner foaming of parent tube after the parent tube moulding, also can with adhesive foam core material and the stubborn bonded assembly mode of parent tube continuation be provided with through foamed materials being processed into required shape.
Tubing skin of the present invention is a metal level, compares with traditional composite frame tubing, and its connection mode that can be suitable for is more, comprises riveted joint, welding, bolted connection etc., helps the composition of vehicle frame.
Parent tube of the present invention is fiber reinforced composite; Therefore have that density is low, light weight, good, the toughness advantages of higher of intensity; Have higher hardness at the exterior metal level of parent tube, but damage resistant and the bump that bears weight are filled low density porous foam core in the inside of parent tube; In the bicycle running process; The open texture of foamed materials can absorb vehicle because of receive impact, shock effect is applied to the load on the vehicle frame, reduces the vehicle frame vibrations, guarantees the reliability of service and the traveling comfort of vehicle frame.
The present invention is simple in structure, and is easy to use, reasonable in design, can make cycle frame lighter, reliable, improves the safety and the traveling comfort that go, is suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing is a structural representation of the present invention.
Among the figure, 1 metal level, 2 hollow basic units, 3 sandwich materials.
(5) specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Embodiment 1:

Embodiment 2:
At forming mould surface spraying layer of metal layer, on this metal level, lay fabric and brushing resin adhesive liquid, or directly lay prepreg, lay finish after, the demoulding behind the resin solidification is treated in the pressurization of mould matched moulds.The required raw MAT'L of an amount of frostproof froth n is packed in the parent tube, and foams, make foam fill up the parent tube cavity, thereby obtain sandwich sandwich construction cycle frame tubing.
Embodiment 3:
Make the composite material parent tube through forming processs such as pultrusion, winding, hot pressing, and form the layer of metal layer on the parent tube surface through fusion spraying, plating, electroforming or other technology.Select suitable foam materials processing to become bar-shaped, diameter is slightly less than the parent tube internal diameter.At foamed materials surface applied adhesion agent, it is inner to insert parent tube, makes it bonding with parent tube.
Embodiment 4:
At forming mould surface spraying layer of metal layer, on this metal level, lay fabric and brushing resin adhesive liquid, or directly lay prepreg, lay finish after, the demoulding behind the resin solidification is treated in the pressurization of mould matched moulds.Select suitable foam materials processing to become bar-shaped, diameter is slightly less than the parent tube internal diameter.At foamed materials surface applied adhesion agent, it is inner to insert parent tube, makes it bonding with parent tube.
The present invention also can be used for weight is required other relatively stricter special box frame except that being used for bicycle composite frame tubing, for example air mode container, Military Shelter, mobile barracks etc.
