Abstract

The utility model provides a bicycle frame which is made of light steel material, mini-type wheels whose diameters are not larger than 400 mm and a single thin accumulator cell whose thickness is not larger than 100 mm. The wheel base is not larger than 950 mm, the total weight of the bicycle is not larger than 28 kg, and the highest hour speed is not larger than 16 km/h. The driving member adopts an electric power axle without change gears nor driving structure, the utility model has the advantages of small volume, simple structure, light weight, low cost, saved power consumption, safe and convenient operation, and the utility model can be moved upstairs by one people. The utility model can be individually driven by electricity, human power or can be combining driven by electricity power and human power.

Description

Minisize electric bicycle

The utility model is a kind of miniature electric bicycle, particularly a kind of dual-purpose light small-sized electric bicycle of manpower, electric power that electronic axletree is housed.

Electrical Bicycle weight in the past is too big, and volume is also big, and noise, cost height are arranged, and uses upkeep cost also high, especially the speed of a motor vehicle is fast, has surpassed the regulation of high speed limit of traffic management system slow lane, and this car is heavy especially in addition, uses inconvenience, and is also dangerous.

The utility model provides a kind of light-weight frame of being made by light steel building material, adopt diameter to be not more than the small-sized wheel of 400mm, wheel base is not more than 950mm, used single thickness to be not more than the slim storage battery of 100mm, and be installed in the car body centre and do not have variable gear, do not establish the electronic axletree of driving device, the front and back wheel carrier is equipped with the shock absorbing apparatus of new structure, full car total weight is not more than 28 kilograms simple in structure, car body is small and exquisite, in light weight, cost is low, the power consumptive province, safe and convenient to use, and can electric power, manpower or unite the miniature electric bicycle of driving.This car one people can carry it upstairs, in being best suited for, the people of the elderly, women and legs and feet inconvenience uses.

Principle of work of the present utility model and structure describe in detail with illustrated embodiments and accompanying drawing:

Fig. 1 is a body construction;

Fig. 2 is circuit theory and device drawing.

One. the vehicle frame part: it is made up of handlebar (21), front fork (1), front shock-proof device twin beams (3), battery cradle and conjuncted shelf (6), accumulator can (28), back shock-absorbing fork (12), front and back vibration damping spring (4) (11), front and back wheel (2), (17), seat rod (30), vehicle seat (32) and pedal rod (7), toothed disc (9), chain (14), flywheel parts such as (15).

Two. the Shock absorber part: front shock-proof device is formed by vibration damping spring (4), shock-absorbing live axle (22) with conjuncted plate of front shock-proof device twin beams and stage clip screw; Back shock-absorbing is made up of back shock-absorbing fork and conjuncted plate (12), back shock-absorbing fork live axle (8), vibration damping spring (11) and battery frame spring top board.

Three. storage battery and drive element: storage battery (5) is that a kind of thickness is not more than the slim power lead-acid of 100mm, 12-24V, or adopts a kind of 24V plastic battery, is installed in the battery cradle (6); Drive element is to adopt that a kind of neoteric (number of patent application is: 89200422) do not have the electronic axletree (16) of variable gear and transmission device, it is installed on the rear wheel (17) by spoke.

Four. it is as described below that principle is made in this turner: (see figure 2) provides electric energy by storage battery (5), and affect the control of backguy branch third gear by turning handle (25): it is out of stock that handle forwards the dead point outward to, and interior commentaries on classics is the slow train shelves for one grade, and changeing second gear outward is fast car stop.Backguy contacts contactless switch last slice contact when promptly moving one grade to middle sheet contact, electric energy is led to electric drive axle through current-limiting resistor with middle sheet by last slice again, make wheel begin to rotate to order about car and advance per hour to be not more than 12 kilometers speed per hours, when handle continues to make backguy affect the middle sheet of contactless switch last slice to touch down sheet toward interior commentaries on classics with the current-limiting resistance short circuit, the electric current of leading to electric drive axle strengthens, and make electric drive axle change fast, order about car 16 kilometers speed per hours with per hour the time and advance.Contactless switch is installed on the position of car body (10).This car Shock absorber is like this work: when the human body seat onboard after because weight strengthens, make spring stress and compress, be expert at when front and back wheel and sail rolling when being uneven the road surface, make spring further compression or outer bullet, make car body play the shock-absorbing effect.

When storage battery power consumption 80%, charge switch can be broadcast " 1 ", it is promptly chargeable that input plug is inserted the 220V civil power, and this charger is installed on the position of car body (29).

Claims

1, a kind of miniature electric bicycle, particularly a kind of manpower, electric power and manpower, electric power that slim storage battery, electronic axletree and front and back Shock absorber are housed is united the small-sized Electrical Bicycle of driving, portions such as the handlebar that it is made by light steel building material, front fork, front shock-proof device twin beams, battery cradle, shell, back shock-absorbing fork, front and back vibration damping spring, front and back wheel, vehicle seat and seat bar, slim storage battery, electronic axletree and pedal rod, toothed disc, chain, flywheel form

Feature of the present utility model is:

1-1. the handlebar that vehicle frame is made by light steel building material (21), front fork (1), front shock-proof device twin beams (3), battery cradle and body frame (6), shell (28), back shock-absorbing fork (12), front and back wheel (2) (17), seat rod (30), vehicle seat (32), pedal rod (7), toothed disc (9), chain (14), flywheel (15) are formed.

1-2. the thickness of storage battery is not more than 100mm, is installed on the car body center together with carriage (6).

1-3. Shock absorber all is housed before and after this car, and it is formed by front shock-proof device twin beams and disjunctor plate (3), shock-absorbing live axle (22), shock-proof spring (4), back shock-absorbing fork and disjunctor plate (12), vibration damping spring (11), back shock-absorbing fork live axle (8) and battery frame spring top board parts.
