Bicycle with rigidity and shock-proof effect

Abstract

The invention relates to a bicycle with rigidity and a shock-proof effect, which comprises a front frame, a rear frame and a shock absorber. The front and the rear frames are adjacent to each other; the rear frame is provided with a group of rear lower forks and a group of rear upper forks; the group of rear lower forks are fixedly connected with the front frame through the first end of each of the rear lower forks respectively and are connected with the first end part of each of the group of rear upper forks through the second end of each of the rear lower forks; and the shock absorber is connected with one second end part of the group of rear upper forks and the front frame. The group of rear lower forks has a rigid structure and cannot rotate, so the bicycle is forced to extrude the front and the rear frames to generate material deformation to act on the shock absorber when bearing a larger external force and the shock absorber slows down the buffeting magnitude of the front and the rear frames; and the group of rear lower forks does not have rotating points, so the lightweight effect is achieved.

Description

technical field [0001] The invention relates to a bicycle, in particular to a bicycle with a rigid shock absorbing effect. Background technique [0002] refer to figure 1 , taking a bicycle frame 1 with a rear shock absorber as an example, it mainly includes a front frame 11, a rear frame 12, and a shock absorber 13. The front frame 11 has an upper tube 111 and a lower tube 112 connected to each other, a tube 113 connecting one end of the upper and lower tubes 111, 112, a head tube 114 connecting the other end of the upper and lower tubes 111, 112, And a bottom bracket 115 connecting the seat tube 113 and the down tube 112 . The rear frame 12 has a chain stay 121 pivotally connected to the bottom bracket tube 115 , and a seat stay 122 connected to the chain stay 121 and the seat tube 113 . The shock absorber 13 is disposed between the seat stay 122 and the seat tube 11 . [0003] Thereby, when the vehicle frame 1 is under force, the front frame 11 or the rear frame 12 wi...

Problems solved by technology

[0004] But, because this front vehicle frame 11 or rear vehicle frame 12 can rotate with the pivot center of this chainstay 121 and this bottom bracket tube 115, therefore, this front vehicle frame 11 and this rear vehicle frame 12 will be because of this Added components at the pivot area, resulting in an increase in overall weight, resulting in a decrease in bicycle performance
