Further, pipe bracing frame before said three turning point link-type automatically-retractable folding bicycles also comprise, wherein,
The pipe bracing frame is captiveed joint with the preceding pipe of said vehicle frame rear portion before said;
The pipe bracing frame is connected with the rotating shaft of said saddle pipe bracing frame before said.
Further; Described three turning point link-type automatically-retractable folding bicycles also comprise the gim peg of managing behind pipe and the vehicle frame before being arranged on a plurality of holes of managing behind the pipe and vehicle frame before the said vehicle frame and being connected said vehicle frame, manage before being used under bicycle use and folded state, fixing said vehicle frame and vehicle frame after the relative position of managing.
Further, the handlebar support is managed through the swivel bearing that the handlebar support is fixed in vertical direction is connected with vehicle frame is preceding.
The scheme that the utility model proposes links up flexible two actions of putting down with saddle pipe of folded bicycle; Through a realization of three turning point bar linkage structures between the pipe behind pipe, the vehicle frame before saddle pipe and vehicle frame, thereby reach the effect that makes the automatic quick-expansion of telescopic folding car folding.
Description of drawings
Fig. 1 is the three turning point link-type automatically-retractable folding bicycle structure scheme drawings that the utility model proposes;
Fig. 2 is the structural representation behind the three turning point link-type automatically-retractable folding bicycle foldings that propose of the utility model.
The specific embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.To different situations, the utility model can have various embodiment.
As shown in Figure 1; The utility model proposes a kind of three turning point link-type automatically-retractable folding bicycles; Comprise: manage 5 behind pipe 4 and the vehicle frame before handlebar (not shown), handlebar support 6, vehicle seat, saddle pipe 3, saddle pipe bracing frame 31, movable rod 1, wheel 2, the vehicle frame, wherein:
Handlebar is rotatable to be installed on the handlebar support, and said handlebar support is connected with the preceding pipe of vehicle frame;
Managing 5 before the said vehicle frame behind pipe 4 and the vehicle frame is sleeve-type and is connected;
Said saddle pipe 3 one ends are installed vehicle seat, and the other end is fixed on the saddle pipe bracing frame 31;
Said movable rod 1 two ends respectively with said saddle pipe bracing frame 31 and said vehicle frame before pipe 4 rotating shafts be connected;
Said saddle pipe bracing frame 31 two ends respectively with said movable rod 1 and vehicle frame after pipe 5 rotating shafts be connected.
Between saddle pipe and vehicle frame, form the connecting rod link gear of one three turning point like this.Therefore; The preferred mode of operation of the utility model is: when folding the use, put upside down following time when saddle pipe 3 retreats, because leverage; Pipe 5 was to the both sides push-and-pull after movable rod 1 promoted preceding pipe 4 of vehicle frame and vehicle frame simultaneously; Pipe 5 is done relative expanding-contracting action after causing preceding pipe 4 of vehicle frame and vehicle frame, realizes that vehicle body folds freely or stretchs out, thereby reaches the folding effect of quick-expansion.
