Further, adopt the pedal mode to move ahead for convenient during when electric energy is not enough or on the hillside, describedly on the middle vehicle frame of standpipe traveller front side, be provided with the axis that is used to be provided with crank and chain-wheel, rear wheel is provided with the flywheel that links to each other by chain gear with described crank and chain-wheel, and the crank end of described crank and chain-wheel is provided with pedal.
Further, safe in utilization for improving, the rear end of described standpipe traveller or vehicle seat is provided with reflector block.
Further, for further reducing the volume after folding, the handlebar on the described stem is a folding handle bar.
The technique effect that the utlity model has: in the folding electric bicycle of the present utility model, behind the rapid deployment rideable use, its folding convenient, volume after folding is less, and is in light weight, is easy to carry.In the process of riding, easily, steadily, be easy to learn artistic cycling.This folding electric bicycle adopts DC disc type DC machine and lithium cell, the device direct drive wheel hub of DC machine, and simple in structure, electrical motor does not take up space, and weight is lighter.The electronic bicycle of this collapsible lithium cell is after folding, and portability is ridden in a bus, subway, elevator, can carry public places such as entering the department store easily; Be particularly useful for the above resident family of Urban House second floor, be convenient to the user and carry the vehicle stair activity.After lithium cell was scrapped, the cost of environmental protection treatment was less.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the deployed configuration scheme drawing of the folding electric bicycle among the embodiment;
Fig. 2 is the foldable structure scheme drawing of the folding electric bicycle among the embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
As Fig. 1-2, the folding electric bicycle of present embodiment comprises: front vehicle frame 1, middle vehicle frame 2, back vehicle frame 3, front vehicle wheel 4, rear wheel 5, handlebar 6, vehicle seat 7 and DC machine 8.
Front vehicle frame 1 is made up of four linkages 11, and the front end of four linkages 11 and stem 61 flexibly connect.
Four connecting joint of four linkages 11 constitute by rotating shaft 12.Between the upper and lower strut of four linkages 11 of front vehicle frame 1 strut bar 13 is housed, supports the location by strut bar 13.Strut bar 13 is scalable, and is extending when folding, guarantees that four linkages 11 of front vehicle frame 1 are located to lower support.
Middle vehicle frame 2 is a carrier, and the preceding end connection of middle vehicle frame 2 is connected with the rear end of front vehicle frame 1, and the rear end of middle vehicle frame 2 flexibly connects by rotating shaft 21 with the front end of back vehicle frame 3.On the middle vehicle frame 2 the standpipe traveller 22 that is connected with vehicle seat 7 is housed.On the middle vehicle frame 2 of standpipe traveller 22 front sides, be provided with the axis 23 that is used to be provided with crank and chain-wheel.Rear wheel 5 is provided with the flywheel that links to each other by chain gear with described crank and chain-wheel, and the crank end of described crank and chain-wheel is provided with pedal.
The arc pull bar 24 that flexibly connects with front vehicle frame four linkages 11 also is housed on the middle vehicle frame 2.
On the middle vehicle frame 2 strut bar 25 that joins with standpipe traveller 22 tops is housed, this strut bar 25 is connected with standpipe traveller 22 tops with torsion spring 27 by upper support piece 26.The bottom of strut bar 25 is connected with lower support piece 28,28 bottoms that are installed in standpipe traveller 22 of lower support piece.The handle 29 of being convenient to the vehicle folding operation is housed on the top of middle vehicle frame 2.
Back vehicle frame 3 links to each other with the rear end of front vehicle frame 2.Back chain stay 31 is extended at the rear portion of back vehicle frame 3, and back chain stay 31 is connected on the center shaft of rear wheel 5.On the back vehicle frame 3 battery case storage box 32 is housed, deposits lithium cell in this battery case storage box 32.
