Shock-absorbing bicycle frame

Abstract

The invention relates to a shock-absorbing bicycle frame comprising a front fork sleeve, a saddle sleeve, a middle shaft sleeve and a rear axle fork frame. A vertical beam is disposed between the saddle sleeve and the middle shaft sleeve, a diagonal beam is disposed between the middle shaft sleeve and the front fork sleeve, the rear axle fork frame includes a rear axle upper rod and a rear axle bottom rod, the rear end of the rear axle bottom rod is fixedly connected with the rear end of the rear axle upper rod, the front end of the rear axle bottom rod is hinged to the vertical beam at the position of a lower vertical beam connecting hole, a shock-absorbing plate is hinged to the front end of the rear axle upper rod, the lower end of the shock-absorbing plate is hinged to the vertical beam at the position of an upper vertical beam connecting hole, a damping spring is hinged to the upper end of the shock-absorbing plate, an upper beam is disposed between the front fork sleeve and the vertical beam and is divided into two section which include an upper front beam and an upper rear beam, and the front end of the damping spring is hinged to the upper beam at the position of an upper beam connecting hole. Vibration is absorbed as far as possible through the deformation of the bicycle frame, and the safety and comfort of a bicycle are effectively improved; and the rear end of the upper front beam is fixedly connected with the left and right sides of the front end of the upper rear beam through bow-shaped connecting beams, thereby preventing a clamping and hanging phenomenon caused by the contact between the damping spring and the human body during contraction.

Description

technical field [0001] The invention relates to a bicycle frame, in particular to a shock-absorbing bicycle frame. Background technique [0002] As the main structure of the bicycle, the bicycle frame connects the various parts of the bicycle and plays an extremely important role in the entire bicycle. Most of the bicycle frames in the prior art are welded by the tubular structure bracket through the triangular frame principle, and the saddle tube shock absorption, front fork shock absorption and other methods used in the shock-absorbing bicycles in the prior art have different degrees of shock absorption. Problems such as poor vibration effect, complex structure, and clamping make the bicycle frame as a whole unable to fully deform and absorb the bumps during driving. When the road conditions are not good, it is easy to cause premature fatigue of the user, affecting safe driving and comfort. . Contents of the invention [0003] The technical problem to be solved by the ...

Problems solved by technology

Most of the bicycle frames in the prior art are welded by tubular structure supports through the triangular frame principle, and the saddle tube shock absorption, front fork shock absorption and other methods used in the shock absorption bicycles in the prior art have different degrees of damping. Problems such as poor vibration effect, complex structure, and clipping make the bicycle rack as a whole unable to fully deform and absorb the bumps during driving. When the road conditions are not good, it is easy to cause premature fatigue of the user, affecting safe driving and comfort.
