Description
Technical field
The present invention relates to transport facility field, in particular to the vehicle frame of a kind of Portable electric bicycle and Portable electric bicycle.
Background technology
Along with the continuous progress that society's science and technology is economic, the running vehicle of the mankind also in continuous develop rapidly, the traffic congestion that the conventional vehicles flying to increase is brought and aerial contamination are also day by day serious, the haze occurred especially in recent years, and its major reason produced is exactly vehicle exhaust.In order to reduce traffic congestion because vehicle too much causes and air-polluting situation, all using the novel traffic transportation means of environmental protection or taking public transport and alleviate the problems referred to above advocating and promote trip energetically all over the world.
The novel traffic transportation means such as storage battery car of environmental protection, although adopt electric energy can protection of the environment, environmental protection, storage battery car itself is heavy, and volume is large, though be carry or deposit all very inconvenient.Storage battery car simultaneously needs particular place to deposit, and as underground parking, social public domain etc., at transportation weight, because its weight is large, does not allow to bring elevator into, high building resident family can not carry, deposit in family; If put in family by the storage battery car of routine, storage battery car metallic element exposes, and easily brings safety hazard, falls or run knock static vehicle or encountered by storage battery car as child, due to storage battery car own wt, probably injures neighbouring people by a crashing object.Because of its volume and weight, storage battery car action radius is limited, is only limitted to outdoor, once car owner will enter as indoor, must first find good place to deposit storage battery car, deposits storage battery car outside and is easy to lose or easily damage during storage.
Although public transport means can play certain walking-replacing tool in addition, the circuit due to public transport means mostly is set, can not meet destination of going directly from departure place.Go to public transport means take a little or from when the taking and a little go to destination of public transport means, can only be moved ahead by walking, inefficiency, and if think time saving and energy saving, portable walking-replacing tool can only be adopted, such as folding bicycle or electrodynamic balance wheelbarrow etc.
But these portable walking-replacing tools use and inconvenience, wherein, folding bicycle volume is larger, use needs repeatedly to fold or launch, use complex steps, simultaneously owing to adopting manpower to drive, waste time and energy, and electrodynamic balance wheelbarrow is due to the structure of its uniqueness, although easy to use, driven by power is laborsaving simultaneously, but the user of electrodynamic balance wheelbarrow is when in use for uprightly to ride, there is larger potential safety hazard, if excessive velocities or misoperation are easy to cause danger, and electrodynamic balance wheelbarrow needs complicated study to grasp early stage, be not suitable for spread.
