Abstract
The utility model relates to an electric driving device which is additionally installed on the basis of the original structure of a bicycle with 12 volt storage battery as power supply and can drive 60 km with one time charging. The utility model is characterized in that an electric machine is arranged at the bottom of the centre shaft of a bicycle frame; power is passed to a rear wheel through a universal joint, a driving lever, a gear wheel; a handle bar inches a push-button switch. The utility model has the advantages of convenient operation, shapely configuration, reasonable structure, high efficiency, convenient operation, no pollution, low cost and easy installation, and an overrunning clutch makes electric and man power drive selections be operated freely. The device is applicable for each specification and type of bicycle and has low center position without influence to pedals.
Description
The utility model is a kind of power driver of bicycle, and it is bicycle and man power to be driven change simple device electronic, the manpower dual-purpose into.
Its design goal is bicycle to be become can do riding of longer distance, can reduce the manpower consumption again, the walking-replacing tool that speed is very fast, simple in structure, effect is comparatively desirable.It adopts the crawl push switch to be contained in the bicycle handle bar, and both hands need not be done other operation in the enforcement, need only give the button a slight press.If parking or change manpower need only unclamp knob, but also manpower, electric power drive simultaneously.Therefore, simple to operate is big characteristics, the user does not just have nervous psychology, this has just increased traveling security, adopt the push switch operation in addition, the intermittent use storage battery helps the discharge of storage battery and the prolongation in service life, and further having brought into play bicycle and be walking-replacing tool is again the function of body-building apparatus.
Ordinary bicycle is adapted as the additional device of manpower, electronic dual-purpose, is different from the regular manpower of design, electronic dual-purpose car.The structure that the former can only depend on bicycle is made more reasonably design, and it is low that its basic demand should be the car load center of gravity, reliable transmission efficient height, simple in structure, elegant in appearance, long service life etc.Therefore the installation site of motor and storage battery and method and corresponding driving system just become the key of repacking.
Usually the method for repacking generally is that motor is installed on the front fork of bicycle front-wheel top at present.Perhaps be installed in the top (dress lock place) of trailing wheel, and, certainly will cause the car load upper shift of gravity center like this, easily skid and wear away cover tire with double-motor cycle casing two sides that directly rub.Perhaps increase handlebar and turn to weight, even also hinder the drawbacks such as installation of schoolbag frame.
The purpose of this utility model reaches like this: the bottom that the motor of outputting power (also have storage battery half) is installed in the bicycle tripod axis with simple and easy anchor clamps, the technical scheme of this design not only greatly reduces the center of gravity of whole car, and gives and realize that reasonable driving type has brought following three kinds of feasible solutions.
1. motor power is passed to trailing wheel by a small-sized universal joint, drive link, freewheel clutch and gear.
2. motor is changed power by horizontal output by a pair of small-sized garden finishing bevel gear cuter, passes to trailing wheel by flywheel (bicycle use), chain, gear (chain wheel).
3. motor changes the bottom transmission that rear tyre is directly ground in horizontal output into by a pair of small-sized garden finishing bevel gear cuter.
The common advantage of three kinds of type of belt drive that the technical program forms is that center of gravity is low, and mounting structure is simple, and the life-span is long, and the transferring power mode is reasonable, the efficient height.The first two kind mode cover tire that do not wear and tear, though the third method mill cover tire, friction cover tire lower portion suitable (rubber in bottom own is thicker wear-resisting).
The installation of this bicycle power driver, to bicycle without any infringement, also needn't remove or reequip any parts on the bicycle, thereby the bicycle function can not reduce, the installation of actuator is applicable to that common specification is most of bicycles such as 28 cun, 26 cun, 24 cun.As long as there is the comrade of manipulative ability to assemble slightly by accompanying drawing.This device as adopt 12 volts, 60 peace/time capacity storage battery once charge, power consumption one kilowatt hour, 60 kms that can travel (level land letter have a rest use), speed per hour 20 kms, 85 kilograms of load-carryings, as mix quick charger, its practical degree will be higher.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the scheme drawing according to bicycle power driver of the present utility model.
Describe in detail according to concrete device details and the service condition that the utility model proposes below in conjunction with Fig. 1.
Power supply storage battery (10) is supplied with, and motor (1) adopts 150 watts of 12 volts of DC series excitation motors to be fastened on cycle frame axis rear side neutral gear place with clamping plate (7) bolts (8).
First kind of type of drive: motor (1) takeoff output is passed to small-sized universal-joint (2), drive link (3), and overriding clutch (4), miniature gears (5), gear (11) give trailing wheel with power.Drive link by bearing (6) by the hind axle bolt.
Second kind of type of drive: add a pair of small-sized garden finishing bevel gear cuter power in the motor and change, pass to big gear wheel (chain wheel) (11) or change by small-sized belt-driving by flywheel (13), chain (14) by horizontal output.
The third type of drive: power directly changes the frictional wheel transmission into by flywheel (13) on second kind of basis.Gear, flywheel, frictional wheel can be with steel, cast irons, mould firmly or nylon is made.
Switch is by knob (9) control, and circuit is seen Fig. 2.
(preceding 2 kinds of modes respectively have model machine)
Claims (5)
1, changes the bicycle and man power driving into a kind of bicycle power driver electronic, the manpower dual-purpose, this actuator driving system can be realized by three kinds of patterns, motor (1) device is at cycle frame axis rear side neutral gear place, and is made up of universal-joint (2) or flywheel (3) drive link (3) or chain (4), leading power-transfer clutch (4), gear (1) or chain wheel, bearing (6); Be primarily characterized in that motor (1) is fastened on vehicle frame axis rear side neutral gear place with anchor clamps.
2, it is characterized in that according to one of the described bicycle power driver of right 1 there is a small-sized universal-joint at motor (1) takeoff output place.
3, it is characterized in that according to two described bicycle power driver of right 1 there is a flywheel at motor (1) takeoff output place.
4, it is characterized in that according to three described bicycle power driver of right 1 there is a frictional wheel at motor (1) takeoff output place.
5, according to the gear in right 1 described a kind of bicycle power driver, flywheel, frictional wheel can be with steel, the casting iron moulds firmly or nylon is made.
