As Fig. 4-shown in Figure 5, the folding back of the present invention compact conformation, volume are little.
Embodiment
Shown in Fig. 1-6, the pole that two shapes of the present invention are identical respectively has a sliding sleeve (front support rod sliding sleeve 12, back stay sliding sleeve 13) on (being divided into front support rod 10, back stay 11).The identical connecting rod (connecting rod I 8, connecting rod II9) of two shapes by the position thereon the rotating shaft of 1/3rd extension position be superimposed and be the X-shaped shape, like this, X type connecting rod has two long-armed and two galianconism, two poles upper end is hinged respectively with two galianconism of 1/3rd length of X type connecting rod, and two long-armed difference of sliding sleeve and X type connecting rod 2/3rds length are hinged on it.When two connecting rods of X type relatively rotate around common axis, when angle diminished between its two galianconism, two poles upper end was close, and two long-armed angles diminish equally, and the coupled sliding sleeve of two long-armed promotions slides to the pole lower end on pole.Like this, two poles are close under the restriction of X type connecting rod and sliding sleeve.When two connecting rods of X type relatively rotate around common axis, when angle magnifies between its two galianconism, two poles upper end away from, two long-armed angles are same to become big, and the pulling sliding sleeve slides to the pole upper end on pole.Like this, two pole lower ends away from, form very big angle.The opposite side of two poles has another X type connecting rod identical with above-mentioned X type connecting rod to be connected with above-mentioned two poles with above-mentioned same way as.Handlebar vertical rod between handlebar 20 and the front fork 4 is two joint plug-in structures, and joint 1 can insert joint 2 under the handlebar vertical rod fully in the handlebar vertical rod, and it is that leg-of-mutton slide rail 7 guarantees that handlebar is consistent all the time with the front fork direction that cross-sectional plane is equipped with in handlebar vertical rod inside.The pin 6 of being with spring leaf 27 is equipped with in handlebar vertical rod outside, joint 2 tops down, after joint 1 was pulled out certain-length in the joint 2 under the handlebar vertical rod in the handlebar vertical rod, pin 6 inserted the through hole of joint 1 in the handlebar vertical rod at the through hole that runs through joint 2 under the handlebar vertical rod that is faced toward under the effect of spring leaf 27 elastic force.The handlebar vertical rod is provided with a U type groove I22 near the front fork place in joint 2 outer vertical tube of front fork 3 lower ends down, and is hinged with front support rod 10 lower ends.One active pull rod (handlebar pull bar 5) is housed on the front support rod sliding sleeve 12 of front support rod 10, and the other end of this active pull rod and vertical tube of front fork 3 upper ends are hinged.Vehicle seat strut bar 14 is that two joint connect-disconnect structures (save 25 on the vehicle seat strut bar, the vehicle seat strut bar is joint 26 down), vehicle seat strut bar joint 26 down is provided with the pin 6 of being with spring leaf 27, the back stay sliding sleeve 13 that the vehicle seat strut bar saves on 26 lower ends and the back stay 11 down is hinged, the vehicle seat strut bar is equipped with and back stay 11 upper end pivotallys attached one active pull rods (vehicle seat pull bar 15) on the joint 26 down, connects vehicle seat 21 on the vehicle seat strut bar on the joint 25.Above-mentioned pull bar (handlebar pull bar 5, vehicle seat pull bar 15) should have same a pair of, is contained in the vehicle body both sides symmetrically.
Driving system support 16 is equipped with secondary driving system 24 and trailing wheel 18, and present embodiment employing diameter is 15 centimetres a front and back wheel.U type groove II23 and back stay 11 lower ends on this driving system support 16 are hinged, and it is hinged with the back stay sliding sleeve 13 on the back stay 11 that driving system support 16 is equipped with an active pull rod (driving system pull bar 17).
When needs launch vehicle body, pull out in the handlebar vertical rod on joint 1 and the vehicle seat strut bar and save 25, hold handlebar 20 and pull vehicle seat strut bar 14 to the car rear simultaneously, make back stay sliding sleeve 13 along back stay 11 upward movements, the driving system pull bar 17 on the back stay sliding sleeve 13 promotes the adapter shaft of driving system support 16 around back stay 11 lower ends and rotates.Promoting the adapter shaft of connecting rod II9 around back stay 11 upper ends with back stay sliding sleeve 13 pivotally attached connecting rod I 8 rotates, connecting rod II9 promotes with it pivotally attached front support rod sliding sleeve 12 and slides to the upper end along front support rod 10, back stay 11 and front support rod 10 respectively under the restriction of connecting rod (connecting rod II9, connecting rod I 8) and sleeve pipe (back stay sliding sleeve 13, front support rod sliding sleeve 12) away from and open very big angle.Promoting the adapter shaft of vertical tube of front fork 3 around front support rod 10 lower ends with front support rod sliding sleeve 12 pivotally attached handlebar pull bars 5 rotates.Each several part launches under connecting rod (connecting rod II9, connecting rod I 8) and the promotion of pull bar (handlebar pull bar 5, vehicle seat pull bar 15, driving system pull bar 17) tractive.Joint 25 and vehicle seat strut bar are connected and fixed by pin 6 and spring leaf 27 between the joint 26 down on the vehicle seat strut bar of vehicle seat strut bar 14, and its structure is identical with spring leaf 27 with pin 6 in the handlebar vertical rod.When folding, extract pin, in joint 2 under the 1 insertion handlebar vertical rod of joint in the handlebar vertical rod, joint 25 inserts under the vehicle seat strut bar and saves in 26 on the vehicle seat strut bar.Hold handlebar and pull vehicle seat strut bar 14 to car the place ahead simultaneously, each several part closes up under X type connecting rod and each pull bar effect.
Folding bicycle of the present invention adopts Foldable handlebar and Foldable pedal, and driving system can be secondary driving system, realizes the secondary transmission by the secondary driving system 24 (as: second grade transmission chain wheel) that is installed on the driving system support 16.
