Abstract
The invention belongs to the field of an electric bicycle, in particular to an electric bicycle with two adjacent wheels. The electric bicycle comprises a front wheel, a rear wheel, a front fork, a rear fork, a handle, a saddle, pedals, a hub type motor, a lithium battery and an electric bicycle controller, wherein the front wheel and the rear wheel are close to reduce the length of the electric bicycle, the diameter of the front wheel is greater than that of the rear wheel, and the diameter of the rear wheel is greater than 35cm; by adopting either a front wheel driving way or a rear wheel driving way of the hub type motor, the saddle is arranged in the middle of the vehicle body nearby the inclined upper part of the rear wheel and is lightly lower, the two pedals are respectively located at the lower parts of the two sides of the front wheel, and the pedals are fixed below the front fork through a support frame; when the electric bicycle is taken, the handle can be rotated backwards for approximately 180 degrees, therefore the length of the bicycle body can be reduced; in addition, the fixed pedals or the folding pedals can be adopted.
Description
Technical field
The present invention relates to a kind of Electrical Bicycle, particularly relate to the Electrical Bicycle that a kind of two-wheel is close.
Technical background
Electrical Bicycle is a revolution of chain-type bicycle, the electrical motor of Electrical Bicycle and battery are two large vitals of Electrical Bicycle, their volume, weight, the structure of performance and new type of drive and Electrical Bicycle is related, by the impact of this kind of factor, it is long that existing Electrical Bicycle also exists vehicle body, overweight problem, this two problems further limit the portability of car, user is inconvenient by bus on Electrical Bicycle band, subway, go to work or when going home, be also not easy to Electrical Bicycle to put on building, move into room, wider universal of above problems affect Electrical Bicycle.
The Electrical Bicycle that is applied as of hub-type electric machine removes transmission device and provides possibility, and the invention of lithium ion battery is the cell apparatus that Electrical Bicycle provides high-energy, small size, light weight, the maturation of these two technology is that the lighting of Electrical Bicycle and miniaturization provide condition;
But still have several factor to constrain reducing of existing Electrical Bicycle volume, one is do not have electricity and the driven by foot through chain system that retains to solve midway, one is the pedal part of putting pin in the middle part of vehicle body, and this two-part existence makes the length of Electrical Bicycle to shorten again; Also have factor to be exactly the requirement of battery-driven car stability in addition, when Electrical Bicycle centre-of-gravity is higher, the length of car can not be too short; These reasons above, the length of existing market major part light electric vehicle is made also to be not suitable for portable, and although part trundle light roadster reduces length and the volume of car, but also sacrifice the exercise performance of car because the friction of rolling of steamboat is large simultaneously, cause driving battery efficiency not high, steamboat Electrical Bicycle is impracticable.There is not yet wheel diameter up to now comparatively large, and the ultrashort Electrical Bicycle that front and back wheel is close.
Summary of the invention
The object of the invention is in order to solve conventional electric bicycle volume excessive cannot be portable problem, do not needing folding vehicle body, under also not sacrificing the prerequisite of sliding performance, proposing the ultrashort type Electrical Bicycle scheme that a kind of two-wheel is close.
The object of the invention is to be achieved through the following technical solutions.
1. the Electrical Bicycle that two-wheel is close, comprises front-wheel, trailing wheel, front fork, back vent, handlebar, saddle, pedal, the mechanical, electrical pond of hub-type electric and controller for electric vehicle; Front and back wheel is close, and front-wheel and trailing wheel edge closest range are less than the half of trailing wheel radius, so just shorten wheelbase, reduce the length of vehicle body; Shortening to compensate vehicle body the stability reduced, taking front wheel diameter to be greater than the design of rear wheel diameter; In order to keep good sliding performance, wheel diameter can not be too little, and rear wheel diameter is greater than 35 centimetres; In configuration aspects, back vent top is connected with the side of vehicle head tube, and front fork neck straight tube is formed through vehicle head tube inside and back vent and is rotationally connected relation; Handlebar is fixed on front fork neck straight tube; Front and back wheel is arranged on front fork and back vent respectively by wheel shaft, and the rotating shaft of hub-type electric machine is exactly the axle of wheel; Saddle is fixed on back vent by strut member, and position is near the oblique upper of trailing wheel; Pedal is the place that cyclist places both feet when riding, two pedals lay respectively at position on the lower side, front-wheel both sides, pedal is fixed on below front fork by bracing frame, or pedal and pedal support adopt integral material to make, and pedal is the part that support bottom bent outward goes out; The power lead of hub-type electric machine is connected with controller for electric vehicle with signal wire (SW).
2., in order to expendable weight and reduction volume, the battery of battery-driven car adopts lithium cell, and lithium cell is connected with controller for electric vehicle by power lead, and lithium cell can be arranged on it electric bicycle, also can be hung onboard by power brick, or be backed on the body by cyclist.
3. battery-driven car adopts the mode of f-w-d or back-wheel drive, and when adopting f-w-d, hub-type electric machine is arranged in the middle of front-wheel; When adopting back-wheel drive, hub-type electric machine is arranged in the middle of trailing wheel.
4. in order to portable, handlebar can rotate backward close to 180 °, and namely handlebar is designed to drive institute's connecting bridge with vehicle head tube central axis for axle, rotates close to 180 ° backward, the length of vehicle body when carrying to reduce; Pedal is perpendicular to pedal support, and pedal can be fixedly connected with pedal support, also can be connected by intermediate rotary shaft, and when being connected by intermediate rotary shaft, pedal can be turned up to pedal arm direction.
Beneficial effect
Contrast all kinds of Electrical Bicycle on the market and prior art, the present invention has following innovative point:
1. the short wheelbase design that two-wheel is close;
2. the comparatively big wheel design in miniature portable bicycle;
3. front wheel diameter is greater than rear wheel diameter;
4. the design of low level saddle;
5. the stretcher of bilateral below front-wheel;
6. after handlebar, transfer nearly 180 °;
The present invention contrasts existing Electrical Bicycle technology, has following remarkable advantage:
1. two-wheel close, short wheelbase, low level saddle, the stretcher of front-wheel bilateral, and the nearly 180 ° of schemes of the rear switching of handlebar, add hub-type electric machine and lithium battery technology, achieve the miniaturization of Electrical Bicycle when not folding link to greatest extent, there is good portability;
2. more high-wheeled design ensure that the sliding performance of Electrical Bicycle, reduces the rolling frictional resistance that wheel is subject to, and improves the capacity usage ratio of battery;
3. front-wheel is greater than the design of trailing wheel, adds the stability of car load, shortens the whole vehicle stability decline brought carried out certain compensation to wheelbase;
4. the design plan of low level pedal and low level saddle reduces center of gravity when riding, and adds stability and safety;
5. the mode of riding that the position relationship of complete vehicle structure, pedal and saddle brings, further increases the safety of riding, and the low and both feet of bicyclist's center of gravity protract, and can when riding lack of equilibrium touch ground and stand firm by both feet easily;
