Description
Technical field
The invention belongs to electric bicycle technical field, more particularly to a kind of folding electric bicycle of optimization design.
Background technology
Electric energy be most cleaning, it is most environmentally friendly, using most convenient and transformation efficiency highest energy form, in the city being on the rise
Under the international situation of the petroleum resources of city's environmental pollution and increasingly exhaustion, particularly in urban transportation increasingly congestion, price of oil going up sky-high
Background under, less with private car, on and off duty and trip uses public transport mode instead and bicycle has become proprietary common recognition.
But bicycle can not meet the requirement of user when far away, or public transport mode includes subway and bus etc.
Usually away from office and residence, it is necessary to which other vehicles are plugged into, this segment distance is gone on a journey.Foldable motor-assisted bicycle
Above-mentioned needs are met, folding electric bicycle is most environmentally friendly, using most convenient, the economical and practical trip vehicles.
As the improvement of people's living standards, the enhancing of low-carbon environment-friendly and green and healthy consciousness, bicycle is once again by people
Favor.But as urban transportation is increasingly crowded, it is substantially not enough to deposit parking space, along with bicycle is easier to be stolen, this
A little problems have impact on the enthusiasm that people cycle trip again.Then people have invented folding bicycle, in the hope of do not ridden in stroke when
Section can be easy to carry, can save parking space during storage again.
For example：Authorization Notice No. is CN100540389, in the Chinese patent of entitled " folding electric bicycle ", is related to
A kind of folding electric bicycle, including handlebar, vehicle frame, saddle, front and back wheel, electric driver, in handlebar support tube with being used for
The pipe internal cavity of the locking sleeve of fixed handlebar support tube is provided with handlebar folder, and the handlebar folder includes being arranged on lock
The first connector in tight sleeve pipe, the 3rd connector in handlebar support tube and respectively with first connector
The second connector that is hinged and can be rotated after handlebar support tube is pulled out from locking sleeve around pin joint with the 3rd connector.Its
Frame, pedal, handlebar and saddle can folding shrinking, with Portable belt and storage.Rechargeable battery and control system
It is hidden in frame cross, all control circuits are built in various pipe fittings, greatly reduces the failure caused by damage, make
Obtain vehicle appearance succinctly attractive in appearance.
Using the folding electric bicycle of such technology it is of course possible to ride using simultaneously folding square Portable belt, but still have
Following shortcoming：
A, its vehicle frame compared with chain by two horizontally disposed crossbeams by connecting, and roof beam structure is integrally horizontal in-line
And it is middle provided with pin joint, it is clear that stress limited strength, security is not good enough.
B, its handlebar support tube are only scalable, it is impossible to fold, structure is not compact enough.
C, its handlebar can not be folded, and structure is not compact enough.
D, its foot-operated or traditional bicycle and man structure, are connected, structure is not compact enough provided with chain with rear wheel drive.
E, damping device is not provided with, ridden not comfortable enough.
F, no parking leg, without car light.Park and not enough facilitate, ride also not safe enough.
G, its brake gear, which have no, exclusively carries out optimization design, and structure is not compact enough.
In summary, the folding electric bicycle uses compact after security, the comfortableness ridden, folding
Property, it is not enough in terms of portability, using effect is preferable not enough.
The content of the invention
To overcome the deficiencies in the prior art, a kind of more compact structure of optimization design of present invention offer, function are more complete, folding
Smaller, the easily portable folding electric bicycle of poststack space-consuming, using effect is more preferable.
