Abstract

The utility model provides a carbon fiber seat bow with a metal reinforcement rod, and the seat bow comprises the metal reinforcement rod and a carbon fiber seat bow body. The metal reinforcement rod is located in the carbon fiber seat bow body. The cross section of the metal reinforcement rod is greater than that of the carbon fiber seat bow body by a range from 20% to 60%. The cross section of the metal reinforcement rod is circular, and the length and shape of the metal reinforcement rod are the same as those of the carbon fiber seat bow body. The cross section of the metal reinforcement rod and the cross section of the carbon fiber seat bow body are concentric. The outer surface of the metal reinforcement rod is closely attached to the inner surface of the carbon fiber seat bow. The beneficial effects of the utility model are that the weight of the carbon fiber seat bow is reduced; the shock strength is greater; the structure is simple; the cost of processing is low; and the efficiency of production is high.

Description

There is the carbon fiber seat bow of metal stirrup

Technical field

The utility model belongs to bicycle and manufactures field, especially relates to a kind of carbon fiber seat bow with metal stirrup.

Background technology

In existing technology, the seat bow of bicycle is one of vitals of bicycle load-bearing, in bicycle running process, seat bow is except bearing manned weight, also can be subject to the impact of different frequency, friction speed, therefore just require bicycle seat bow thering is high-intensity certain Dent resistance that simultaneously also has.The seat bow of prior art is generally metal pedestal bow, and its weight is large, intensity is limited, and the carbon fibre material of the present light-high-strength of widespread use is on the market also because its fragility is compared with depositing greatly certain potential safety hazard.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of carbon fiber seat bow with metal stirrup, is particularly useful in the middle of requirement quality bicycle light, excellent in cushion effect.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of carbon fiber seat bow with metal stirrup, comprise metal stirrup and carbon fiber seat bow body, and described metal stirrup is positioned at the inside of described carbon fiber seat bow body;

Further, the cross section of described metal stirrup is circular;

Further, described metal stirrup is embedded in described carbon fiber seat bow body and agrees with it;

Further, the cross section of the cross section of described metal stirrup and described carbon fiber seat bow body is concentric;

Further, the inside face of the outside face of described metal stirrup and described carbon fiber seat bow fits tightly;

Further, described metal stirrup is any in copper bar, aluminium bar, stainless steel and rod of metal alloy thereof;

Further, described metal stirrup is metal tube;

Further, the sectional area of described metal stirrup is the 20%-60% of the sectional area of described carbon fiber seat bow body.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, make the quality of seat bow lighter, impact strength is larger; Have simple in structure, tooling cost is low, production efficiency advantages of higher.
