Description

A kind of novel permanent magnetic assisted electric bicycle

Technical field

The utility model relates to a kind of novel permanent magnetic assisted electric bicycles.

Background technique

With the rapid development of social economy, people require energy conservation and environmental protection increasingly deep.Electric bicycle is people day It often goes on a journey one of important vehicles.How it to be more energy-saving and environmentally friendly electric bicycle, increases course continuation mileage, this is also that people are general All over concern.And existing technology, people only consider from increase battery capacity or manpower power-assisted this respect, it is existing Technology need to be innovated improvement from other aspects.

Utility model content

Purpose of utility model:

The purpose of this utility model is to provide a kind of novel permanent magnetic assisted electric voluntarily using the magnetic force property of permanent magnetic iron Vehicle.

Technical solution:

In order to achieve the goal above, the utility model provides a kind of novel permanent magnetic assisted electric bicycle, including front-wheel, Rear-wheel, vehicle frame, operation handle, controller, permanent magnetic attraction device, Magnetic rotary disc, chain, chain drum flywheel with hub motor, in Suck-pull switch, rotary switch, rotary switch return spring, close switch above pony axle, collector ring and permanent magnetic attraction device pass Sensor.The permanent magnetic attraction device body shell is computed design by diamagnetic material and permeability magnetic material and is made, and centre is cylindrical hole, To place cylindrical magnet iron.Cylindrical magnet iron is placed in permanent magnetic attraction device body shell, and rotary switch controls permanent magnet N Pole and S extreme direction.When the pole the N pole S and both sides diamagnetic body are in alignment, permanent magnet magnetic line is in closed circuit state, and permanent magnetism is inhaled Power device is generated without magnetic force (suction).When the pole the N pole S and both sides magnetizer are in alignment, permanent magnet magnetic line is in open circuit shape State.Permanent magnetic attraction device generates magnetic force (suction)；The permanent magnetic attraction device is installed on permanent magnetic attraction device by the angle position of setting In fixing seat and Magnetic rotary disc and the maximum suction surface of permanent magnetic attraction device generation is in opposite installation；On the Magnetic rotary disc forever Suck-pull switch on magnetic attraction device passes through hollow axle wire hole with electric wire and is connected with collector ring；The rotary switch return spring It is installed on knob lid and knob handle by set angle position, the suck-pull switch pin on suck-pull switch is connected with knob handle.Setting Suck-pull switch power-off, return spring return, rotary switch control permanent magnetic attraction device and generate suction.It sets suck-pull switch to be powered, knob Switch control permanent magnetic attraction device suction disappears.

Innovation as the utility model improves, creative that diamagnetic material is applied to the innovation of magnetic technique forever In magnetic attraction device shell.

Further innovation as the utility model improves, and the design of permanent magnetic attraction device creativeness is installed on Magnetic rotary disc It is in opposite installation in the permanent magnetic attraction device fixing seat and most strong suction face of two permanent magnetic attraction devices.

Another step as the utility model, which is innovated, to be improved, and a set of magnetic driving mechanism of creative design is set to this wound In new vehicle frame.

The permanent magnetism assisted electric bicycle of the utility model passes through operation handle and controller rear wheel, rear wheel When hollow axle rotation driven by rear axle flywheel and chain, chain drum flywheel, hollow axle drives Magnetic rotary disc to rotate again. Controller controls the generation of permanent magnetic attraction device suction by approach switch sensor or disappears.When the permanent magnetic attraction device on Magnetic rotary disc Two permanent magnetic attraction devices all generate suction when keeping off the permanent magnetic attraction device in permanent magnetic attraction device fixing seat.Because solid on Magnetic rotary disc It surely is in opposite installation equipped with permanent magnetic attraction device and with the permanent magnetic attraction device in permanent magnetic attraction device fixing seat in front of Magnetic rotary disc, so Permanent magnetic attraction device power-assisted Magnetic rotary disc rotation in permanent magnetic attraction device fixing seat, Magnetic rotary disc passes through hollow axle again, chain drum flies Wheel, chain, rear flying wheel drive rear wheel.When the permanent magnetic attraction device on Magnetic rotary disc is close in permanent magnetic attraction device fixing seat When permanent magnetic attraction device reaches set distance, controller control suck-pull switch movement makes two permanent magnetic attraction devices while losing suction, Permanent magnetic attraction device non-resistance on Magnetic rotary disc is rotated away from the permanent magnetic attraction device in permanent magnetic attraction device fixing seat.Rear-wheel is logical in this way The transmission mechanism crossing rear axle flywheel and being located on vehicle frame, permanent magnetic attraction device in permanent magnetic attraction device fixing seat just power-assisted magnetic force Turntable rotation so that drive rear wheel again.

The utility model has the advantages that

The novel permanent magnetic assisted electric bicycle of the utility model is compared with traditional electric bicycle, diamagnetic material technology Innovative applies in permanent magnetic attraction device and magnetic driving mechanism in the innovation technology, and structure novel, magnetic force directly utilizes, The course continuation mileage of electric bicycle can effectively be increased, therefore be more energy-saving and environmentally friendly.
