Abstract
The utility model relates to a folded bicycle frame, particularly relates to the folded bicycle frame having a damping function. The folded bicycle frame having the damping function comprises a front fork sleeve, a saddle casing pipe, a central shaft casing pipe and a rear shaft yoke and is characterized in that a vertical beam is arranged at the lower end of the saddle casing pipe; an inclined beam is arranged on one side of the front fork sleeve; the inclined beam is provided with two sections which are connected through a folder; the rear end of the inclined beam is connected with the vertical beam; the central shaft casing pipe which is arranged at the front end of the rear shaft yoke is hinged to the bottom of the rear section of the inclined beam through a hinged shaft; a connecting frame is arranged between the upper end of the rear shaft yoke and the hinged shaft; the upper end of the rear shaft yoke is hinged to the connecting frame; a damping spring is arranged between a hinged position and the folder. According to the folded bicycle frame having the damping function, the bicycle safety and comfort are improved due to the fact that the vibration is absorbed through deformations of the bicycle frame; the strength of the frame is effectively reinforced due to the fact that the cross section of the inclined beam is in a rectangular shape and an reinforced beam is arranged between the rear end of the inclined beam and the vertical beam; the integral effect of the bicycle is improved and the structure is stable due to the fact that a rear tail frame is integrally connected to the upper portion of the rear shaft yoke.
Description
Technical field
The utility model relates to a kind of folding bicycle frame, relates in particular to a kind of folding bicycle frame with shock-absorbing function.
Background technology
In prior art, the vehicle frame of bicycle generally comprises for the front fork sleeve of front fork is installed, for the saddle sleeve pipe of saddle is installed, for the axis sleeve pipe of axis is installed, between front fork sleeve and saddle sleeve pipe, by upper beam, connect, between axis sleeve pipe and front fork sleeve, by cant beam, connect, and by vertical beam, be connected between saddle sleeve pipe and axis sleeve pipe, also establish in addition for the rear axle crotch of trailing wheel is installed, rear axle crotch one end is used for installing rear axle, the other end is fixedly connected with axis sleeve pipe, existing folding bicycle is that upper beam is divided into two sections, and centre connects by folder.
But in prior art, because rear axle crotch is fixedly connected with axis sleeve pipe, make the bicycle rack on the whole cannot deformation and absorb jolting in driving process, when pavement conditions is bad, easily cause the fatigue that user is too early, affect safety traffic and comfort level.
