Abstract
The utility model discloses an electric friction booster for a bicycle. The utility model relates to the booster of the bicycle. The motive force source of the utility model is arranged on a motor of the bicycle. A power supply of the motor is an accumulator along with the bicycle. The motor is provided with a friction wheel, the friction wheel is pressed on tyre covers of the bicycle, and the friction wheel can directly drive wheels of the bicycle to rotate by friction force.
Description
Technical field: the utility model is a kind ofly to be used in electrical motor on the bicycle and man as the device of auxiliary power, and the power supply of electrical motor is from storage battery.
Background technology: bicycle is the vehicle that people use always, and with cheap, speed is moderate, is easy to usely liked by broad masses.But bicycle needs manpower to step after all, to the relatively poor people of some physique or stroke people far away or wish that the labour-saving people should be with dynamic promotion.So various motor bikes and Electrical Bicycle arise at the historic moment.Motor bike generally uses combustion engine as power, though Electrical Bicycle is power with the electrical motor, drives wheel with the wheel chain transmission.And the utility model is in order to be contained in the cover tire that friction wheel on the motor reel directly drives bicycle bicycle to be advanced.Still a kind of morpet also is to drive cycle casing with rubber friction wheel, but this morpet with combustion engine as power.
Summary of the invention: the purpose of this utility model just provides a kind of device that can be installed in easily on the existing bicycle, and this device uses electrical motor as power, and can not only save and step on the muscle power of stepping on bicycle, and the protection environment, simple in structure, cheap.
The purpose of this utility model is to realize like this, with fixed support motor mounting on the front fork of bicycle, one friction wheel of making as glue or other materials is housed on the motor rotation axis, friction wheel is pressed on the cover tire of bicycle quick, friction wheel rotates and can frictionally to drive bicycle quick and rotate, and electrical motor is connected on the storage battery with car by speed control switch.When bicycle is set out on a journey, open speed control switch, electrical motor rotates, and friction wheel drives wheel, reaches the purpose of electric boosted drive bicycle.
Bicycle is to use the vehicle very widely at present, for laborsaving, install engine installation additional and can select combustion engine for use on bicycle, but the Structure of Internal-Combustion Engine complexity is installed trouble, and easy break-down has exhaust emission again simultaneously, and noise is also big.If select for use this device to install on the bicycle, not only there is not above-mentioned shortcoming, expense is also cheap relatively.
Description of drawings: accompanying drawing 1 is the front erection plan that the utility model is installed in bicycle front fork.
The specific embodiment: followingly be described further with the example of executing of the present utility model, contrast accompanying drawing 1, support 1 is fixed on the both sides of the front fork 2 of bicycle, a hinge axis 3 (it acts on the axle of similar hinge for door and window) is equipped with in the upper end of support 1, the other end of hinge axis 3 is equipped with electrical motor 4, therefore motor 4 can move around hinge axis 3 rotations, one rubber friction wheel 5 fixedly is housed on the turning cylinder of electrical motor 4, frictional wheel 5 is pressed on the cover tire 6 of bicycle front-wheel, hook has an extension spring 7 below the electrical motor, extension spring 7 other ends are hooked in to be regulated on the gong bolt 8, and the length of regulating gong bolt 8 can be regulated the pulling force of 7 pairs of electrical motors 4 of extension spring, has also just regulated 5 pairs of car wheel covering 6 pressure of frictional wheel.Electrical motor 4 connects storage battery 9 by speed control switch 8.Storage battery 9 can be contained in by the shelf of bicycle, when bicycle is set out on a journey, opens speed control switch 8, and electrical motor 4 rotates, and frictional wheel 5 drives wheel, and bicycle just can obtain power-assisted and advance.
