Abstract
The utility model discloses a carbon fiber bicycle frame structure which comprises a head tube, an upper tube, a lower tube, a base tube, a five-joint part, a rear upper fork and a rear lower fork. The upper end of the base tube is respectively and fixedly connected with the rear upper fork and one end of the upper tube, the lower end of the base tube is respectively and fixedly connected with the rear lower fork and one end of the lower tube through the five-joint part, the rear upper fork is fixedly connected with the other end of the rear lower fork together, and the upper tube is connected with the other end of the lower tube together through the head tube. The included angle formed between the head tube and the horizontal plane is 72 degrees. The carbon fiber bicycle frame structure is stable and comfortable in riding and conforms to human engineering.
Description
Technical field
The utility model relates to a kind of bicycle, refers in particular to a kind of carbon fiber bicycle body frame structure for automotive.
Background technology
Cycle frame, as the skeleton of whole bicycle, farthest determines, affects correctness and the traveling comfort of riding posture.That carbon fiber bicycle vehicle frame has is lightweight, good springiness, drive that sense is stable, long-distance tracking continues the characteristics such as sense is good, traveling comfort is high, can absorb the impact on ground, and the repelling force of material is fast, is desirable cycle frame material.
From the stressing conditions analysis of cycle frame, wherein, middle pipe is mainly subject to rider's pressure, ground passes to Seat stay by trailing wheel, the antagonistic force of pipe in Seat stay passes to, and ground passes to upper pipe by front-wheel, the antagonistic force of pipe in upper pipe passes to; Head tube is mainly subject to the antagonistic force that transmit by front-wheel on ground; And five-way becomes the stressed bearing point of whole bicycle, it overhead highly determines stressing conditions.
Due to, carbon fiber bicycle vehicle frame own wt is lighter, the more common vehicle frame of its center of gravity changes, therefore, the angle of pipe and horizontal surface in need to adjusting in carbon fiber bicycle vehicle frame, the angle of head tube and horizontal surface, and five-way is apart from the distance of horizontal surface, make whole carbon fiber bicycle vehicle frame meet aerodynamics and ergonomics, this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of and drives steadily comfortablely, meets the carbon fiber bicycle body frame structure for automotive of ergonomics.
For reaching above-mentioned purpose, solution of the present utility model is:
A carbon fiber bicycle body frame structure for automotive structure, comprises head tube, upper pipe, lower pipe, seat pipe, five-way, Seat stay and Chain stay; Seat pipe upper end is fixedly connected with respectively Seat stay and ，Zuo Guan lower end, upper pipe one end is fixedly connected with respectively Chain stay and lower pipe one end by five-way; Seat stay and the Chain stay other end are fixed together; The other end of upper pipe and lower pipe links together by head tube; The angle of head tube and horizontal surface is 72 °.
Further, seat pipe is 73 ° to 73.3 ° with the angle of horizontal surface.
Further, the distance of five-way width between centers horizontal surface is 268mm.
Further, also comprise front-wheel, trailing wheel and front fork; Front fork is movably arranged in head tube, and front-wheel is arranged on front fork; Trailing wheel is arranged on Seat stay and Chain stay junction; Total wheelspan of front-wheel and trailing wheel is 986mm.
Adopt after such scheme, the angle of the utility model head tube and horizontal surface is 72 °, and it is sensitiveer that this angle rotates front-wheel, lighter in driving process, and the relatively good control in left and right drives steadily comfortablely, meets ergonomics.
Seat pipe is 73 ° to 73.3 ° with the angle of horizontal surface, further makes to drive steadily comfortable, meets ergonomics.
The distance of five-way width between centers horizontal surface is 268mm, and in the process of riding, front axle, rear axle become a triangle with gravity center of human body, and described data make triangle more steady, comfortable, thereby it is comparatively steadily comfortable that rider is driven.
Total wheelspan of front-wheel and trailing wheel is 986mm, makes turning of bicycle than very fast, more smooth-going in the process of riding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Label declaration
On seat pipe 1, manage 2
Lower pipe 3 five-ways 4
Head tube 5 Seat stays 6
Chain stay 7 front-wheels 8
Trailing wheel 9.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Consult shown in Fig. 1, a kind of carbon fiber bicycle body frame structure for automotive structure that the utility model discloses, comprises seat pipe 1, upper pipe 2, lower pipe 3, five-way 4, head tube 5, Seat stay 6 and Chain stay 7.
Seat pipe 1 upper end is fixedly connected with respectively Seat stay and upper pipe 2 ，Zuo Guan lower ends, one end are fixedly connected with respectively Chain stay 7 and lower pipe 3 one end by five-way 4.Seat stay 6 and Chain stay 7 other ends are fixed together.The other end of upper pipe 2 and lower pipe 3 links together by head tube 5.Head tube 5 is 72 ° with the angle of horizontal surface, and it is sensitiveer that this angle rotates front-wheel, lighter in driving process, and the relatively good control in left and right drives steadily comfortablely, meets ergonomics.
In the present embodiment, the angle of seat pipe 1 and horizontal surface is 73 ° to 73.3 ° further to be made to drive steadily comfortable, meets ergonomics.
In the present embodiment, the distance of five-way width between centers horizontal surface is 268mm, and in the process of riding, front axle, rear axle become a triangle with gravity center of human body, and described data make triangle more steady, comfortable, thereby it is comparatively steadily comfortable that rider is driven.
The utility model also comprises front-wheel 8, trailing wheel 9 and front fork (not shown); Front fork is movably arranged in head tube 5, and front-wheel 8 is arranged on front fork.Trailing wheel 9 is arranged on Seat stay 6 and Chain stay 7 junctions.Front-wheel 8 is 986mm with total wheelspan of trailing wheel 9, makes turning of bicycle than very fast, more smooth-going in the process of riding.
The foregoing is only preferred embodiment of the present utility model, the not restriction to this case design, all equivalent variations of doing according to the design key of this case, all fall into the protection domain of this case.
