Description
Technical field
The present invention relates to the folding bicycle field, particularly, relate to a kind of three turning point link-type automatically-retractable folding bicycles.
Background technology
Usually, folding bicycle can be used the up-down rim brake makes the car load axle center upwards promote the integral structure of the axle center type Portable folding hand cart that is folded into ultra-small volume, puts the integral structure that becomes folding bicycle in the cloth bag (case and bag) into after car load is folding.On the make then need vehicle frame and tap, vehicle seat be connected with the locking hinge; The locking hinge is equipped with spring, cable wire (cable brake) etc., handled easily; Up-down rim brake may command locking hinge is guaranteed safety and convenient.
In fact, general telescopic folding bicycle is after preceding pipe is flexible, and saddle pipe also need stretch or folding putting down.Therefore, this folding process needs two actions, and process is loaded down with trivial details, is inappropriate for old man or children and uses.
Summary of the invention
The present invention stretches folded bicycle for realization and puts down the merging of these two actions with saddle pipe, has designed a kind of three turning point link-type automatically-retractable folding bicycles.
The present invention proposes a kind of three turning point link-type automatically-retractable folding bicycles, comprising: manage behind pipe and the vehicle frame before handlebar, handlebar support, vehicle seat, saddle pipe, saddle pipe bracing frame, movable rod, wheel, 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;
Manage behind pipe and the vehicle frame before the said vehicle frame and be sleeve-type and be connected;
Said saddle pipe one end is installed vehicle seat, and the other end is fixed on the saddle pipe bracing frame;
Said movable rod two ends respectively with said saddle pipe bracing frame and said vehicle frame before the pipe rotating shaft be connected;
Said saddle pipe bracing frame two ends respectively with said movable rod and vehicle frame after the pipe rotating shaft be connected.
Further, pipe volume is managed after less than said vehicle frame before the said vehicle frame, and pipe can be close to the outer move of pipe before the said vehicle frame behind the said vehicle frame.
Further, said three turning point link-type automatically-retractable folding bicycles also comprise back pipe bracing frame, wherein,
Manage behind said back pipe bracing frame and the said vehicle frame and anteriorly captive joint;
Said back pipe bracing frame is connected with the rotating shaft of said saddle pipe bracing frame.
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 present invention 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 present invention proposes;
Fig. 2 is the structural representation behind the three turning point link-type automatically-retractable folding bicycle foldings that propose of the present invention.
The specific embodiment
Elaborate in the face of embodiments of the invention down, present embodiment provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment being to implement under the prerequisite with technical scheme of the present invention.To different situations, the present invention can have various embodiment.
As shown in Figure 1, the present invention proposes a kind of three turning point link-type automatically-retractable folding bicycles, comprising: 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 present invention 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.
In a preferred embodiment of the present invention, pipe volume is managed after less than said vehicle frame before the said vehicle frame, and pipe 5 is close to pipe 4 outer move before the said vehicle frame behind the said vehicle frame.Pipe 4 is managed in 5 after can just inserting vehicle frame before the vehicle frame, makes full use of space resources.
