Abstract

Disclosed is a land vehicle for traveling otherwise than on rails, in particular to an electric bicycle. In the utility model, both ends of the axle shaft of a front wheel and both ends of the axle shaft of a back wheel are respectively provided with electric vibration generating devices. The axle shaft of the back wheel is provided with a permanent magnet type motor with an outer rotor, and the outer rotor is connected with bicycle rims. In run, the bump of the vehicle drives the electric vibration generating device to endlessly generate current which charges an electric jar after rectified, and the electric jar works under a light load. The service life of the electric jar is extended, energy consumption and running cost are reduced, and running mileage is increased after charge for one time.

Description

Electric bicycle

The utility model relates to a kind of trackless terrestrial vehicle, particularly Electrical Bicycle.

The Electrical Bicycle of current domestic and international use generally all adopts the storage battery power supply, and Here it is charges in storage battery in advance, on the way travels then.This vehicle, every charging once, consumes energy not only, its travelled distance is also all shorter, and storage battery is travelled under the power shortage situation, causes storage battery early ageing, the lost of life, this has not only strengthened over-the-road expense, and use also very inconvenient.

The purpose of this utility model is that a kind of improved Electrical Bicycle will be provided, and it not only can prolong the life-span of storage battery, and energy savings reduces charging times, and can prolong once electrically-charged traveling mileage.

The utility model is to realize like this, according to 1987,6, the 16 ZL86205352 vibration generating device utility model patents of authorizing, axletree two ends at the front-wheel and the trailing wheel of Electrical Bicycle, respectively adorn an improved above-mentioned power generation assembly, utilize people's function that wheel jolts naturally when normally riding, make power generation assembly produce exchange current because of jolting, through charging to the storage battery on the car behind the bridge rectifier, keep storage battery under the light load state, to work, thereby prolonged the service life of storage battery, reduce the energy, prolonged travelled distance.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1: Electrical Bicycle scheme drawing

Fig. 2: vehicle-mounted vibration generating device partial schematic sectional view

Describe concrete structure of the present utility model and service condition thereof in detail below in conjunction with Fig. 1,2.

This Electrical Bicycle is made up of front-wheel, trailing wheel, vehicle frame, handlebar, vehicle seat 1, driving device, storage battery 14 all parts; At the axletree two ends of front-wheel and trailing wheel a vibration generating device 2 is housed respectively, the magneto outer rotor motor 3 through the electronics stepless time adjustment is housed on hind axle, this electrical motor outer rotor is connected on the rim through spoke; Vibration generating device 3 is the shock absorbers that are made of spring 5, and the extremely staggered permanent magnet 10 of multilayer N, S by epoxy resin is bonded at anchor shaft 6 both sides is positioned at the overlapping silicon steel plate 12 of multilayer permanent magnet both sides and the winding 11 that is wrapped on the silicon steel plate 12 and constitutes.The lower end of anchor shaft 6 is fixed on the wheel shaft, the upper end links to each other with spring 5, silicon steel plate 12 is connected with end cap 9 by screw 8, and end cap 9 fuses with the nut 4 that is used for being connected car body that is positioned at spring 5 tops, when riding, because pitching of wheel, the pressure that produces, spring 5 is constantly shunk and elongation, so, silicon steel plate 12 and winding 11 promptly insulated shell 13 in and anchor shaft 6 and attached thereon multilayer permanent magnet poles 10 under the restriction of axle sleeve 7, do relative motion, the winding 11 that is around on the silicon steel plate 12 is cut repeatedly be positioned at the magnetic line of force that the one side is produced by multilayer permanent magnet 10, the electric current that produces constantly carries out floating charge for storage battery 14 through the bridge rectifier circuit in the vehicle seat 1 like this, storage battery 14 is worked under light load, thereby prolonged the service life of storage battery, reduced energy consumption, increased the traveling mileage after once charging.For ease of trailing wheel with the injustice of physical features heave and set, increase the usefulness of vibration generating device, on axis and support that rear axle is connected, be provided with active pin shaft 15, and employing solid rubber wheel band, but all absorbed owing to winnow with a dustpan top of the two-wheeled, still feel very comfortable so ride the time spent by the spring 5 of vibration generating device under the vehicle seat.Certainly, concrete effect of the present utility model, smooth degree with road, the wind direction of meeting has substantial connection in riding, and experiment shows, when adopting 12 ampere hour storage batterys, in the antero posterior axis end, vibration generating device with 10 pairs and 20 pairs magnetic poles is installed respectively, and traveling is on general rural highway, and its traveling mileage that once charges can increase about 1/2～3/4.In addition, used storage battery also available chemical capacitor replaces, and the used vibration generating device of the utility model also can be made into the generator set of the larger capacity of auto-excitation type or independent-excited, is used for other various multi-wheeled vehicles.

The utility model is owing to adopted the magneto outer rotor motor, saved excitation electric power, and vehicle is when riding, constantly charge from the trend storage battery, thereby keep storage battery under the light load state, to work, prolong storage battery service life, reduced energy consumption and cost, increased the once traveling mileage of charging.
