Abstract

The utility model relates to an electrical bicycle driving device. The utility model takes an accumulator cell as the electrical energy and two stators as the motive power of a DC electric motor of a permanent magnetic shoe, two anti-friction wheels which are driven by the electric motor can be directly clamped at the two sides of the back tire of the bicycle, and therefore, the bicycle can be driven to automatically run. The utility model has the advantages of simple device and safe operation, which can be arranged on any existing bicycle, the speed is 20 km/h, and the utility model can run 50 km with a charging for one time.

Description

Electrical bicycle driving device

The utility model is the device that a kind of electricity consumption drives bicycle running, the particularly a kind of electricity consumption device driven that can install and use on existing plurality of bicycles.

Existing bicycle is the vehicle that people ride instead of walk, so-called " bicycle " in fact can not be voluntarily but by riding a kind of rickshaw that travels, though this car is gently faster compared with walking, but physical demands is still very big concerning the rider, and especially the people of centering, the elderly, women and legs and feet inconvenience is just more painstaking.

In order to overcome cyclist's physical demands, bicycle is really reached voluntarily, common way is that a cover put-put is installed on bicycle, but this class engine noise is big, smoke pollution is big, oil consumption is many, complicated operation is also dangerous, China's withdraw from use in the city.

A kind of Electrical Bicycle (spy opens clear 54-151241) China has been invented by MAT has introduction " external daily necessities " the magazine first phase in 1981, this is a kind of complete two-wheeled electrocar, it is located at the rear wheel frame position with most important storage battery, after making center of gravity partially, cause the handlebar shakiness, influence safe driving.Electrically operated transmission, the speed reduction gearing gear is many, and complex structure increases power consumption, involves great expense.Car body is special in electronic purpose made, can not utilize existing self-moving vehicle.

Task of the present utility model is to provide a kind of electricity consumption that can install on existing plurality of bicycles to drive the device that travels, it both can make the independent electricity consumption of bicycle drive and travel, also can ride separately to drive and travel, against the wind, when climbing and load-carrying, but also electricity consumption, drive simultaneously with pin and to travel.

The utility model is finished as follows; a cover is installed by small battery in two support beam middle parts below the bicycle crossbeam; carriage; charging socket; the power-supply system that protecting sheathing is formed; in bicycle stand rear lower position one cover being installed is permanent magnetic tile formula DC motor by two stators; an extrapolation spring; two friction wheels; a chassis; two groups of wet contacts and the drive system that protecting sheathing is formed are installed a cover and are pinched the clutch brake lever by hand on bicycle handle bar; steel rope backguy and the power-transfer clutch control loop that links with two motor casing tops of drive system.When bicycle needs electricity consumption to drive, pinch clutch brake lever, steel rope pull back with hand, each is drawn close toward the center to make two electrical motors.When being brought to two groups of wet contact energized, be installed in anti-being clipped on the rear tyre both sides of the anti-wheel of friction on the motor spindle nose, this moment, two electrical motors respectively rotated to center position, drive bicycle rear and rotate and travel forward, as when stopping electricity and driving, apply the handbrake because the extrapolation action of the spring makes the steel rope backguy as long as let hand go, electrical motor, wet contact, the anti-wheel of friction all disengagement resets, and this moment, car body also can slide by self being used to power.When using foot-operated the driving when travelling instead, only otherwise pinch clutch brake lever and ordinary bicycle to ride method identical, when the needs bicycle against the wind, when climbing or load-carrying are travelled, ride the purpose that can reach the associating driving again simultaneously as long as pinch brake lever.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the utility model concrete structure scheme drawing.

Fig. 2 is schematic circuit diagram of the present utility model.

Describe in detail according to an embodiment who the utility model proposes below in conjunction with accompanying drawing.

The structural principle of this device is as described below, (7) are that a capacity is 12V, the dry charged battery in 36～40 peace/times in the accompanying drawing, it is whole energy of this device, and for this storage battery of expendable weight is keeping under the prerequisite of 12V36～40 peace/hour capacity, its volume weight is the smaller the better; (9) be battery cradle, the most handy light weight of this carriage, high strength, resistant material are made, as glass-felt plastic engineering plastics etc.; by above-mentioned storage battery (7); battery cradle (9), charging socket (8), accumulator protecting shell (10) constitutes power-supply system.(1) is two permanent magnetic tile formula DC motor, every output power of motor is 60W, the stator of electrical motor is owing to adopted ferrite, plumbous nickel cobalt, the material of Rare-Earth Cobalt and neodymium iron is done permanent magnetic tile, every output power of motor is under the situation of 60W, its electric power is 54W, two electrical motors are owing to adopt permanent magnetic tile to make stator, but power saving 12W, these two electrical motors are in order to reach same power, electrical motor that inhour is rotated wherein, except that the power positive cathode reversal connection, the position of carbon brush needs 45 ° of cw changes, and the rotor winding joint needs whole reverse grafts on copperhead, and to 45 ° of cw displacements, (2) are two anti-wheels of aluminum friction; (3) be fixedly snap ring of steel rope backguy, it is that one is divided into two strands with the tail end of steel rope backguy, and root is put on the spot with steel wire, and afterbody curves two circles, also puts on the spot with steel wire, and the useful steel wire of institute all welds with scolding tin around locating; (4) be two groups of silver contacts, the fixed point of contact is installed on the motor base, and contact moving is installed in insulation mode on the crust of electrical motor afterbody; (5) be an extrapolation spring, be fixed on the base with the steel wire coiling of 1.5m/m; (6) be motor base, be fixed on bicycle stand bottom, constitute drive system by above-mentioned (1), (2), (3), (4), (5), (6) and shell strap with two clamping plate.(11) be the clutch brake handle, (12) are one group of steel rope backguys, more than two parts can be with the transformation of the way of bicycle rear backguy lock, by (11), (12) and steel rope slack adjuster formation clutch control loop.

The utility model job procedure is as described below, when bicycle needs electricity to drive, clutch brake lever (11) is pinched, steel rope (12) is pull back, two electrical motors are drawn close toward the center, when being brought to two groups of silver contacts (4) energized, and two anti-being clipped on the rear tyre both sides of the anti-wheel of friction, each rotates two motors (1) to center position, drives that bicycle rear rotates and to overtake.As when stopping electricity and driving, as long as let clutch brake lever (11) go, take turns (2) because the effect of extrapolation spring (5) resists steel rope backguy (12), electrical motor (1), wet contact (4), friction, all throw off and reset, this moment, car body also can slide a segment distance by self being used to power as not braking.This device can make bicycle per hour travel about 20 kilometers.This device has a socket (8) when needs charge, and the input plug insertion charging socket (8) of battery charger is promptly chargeable.Whenever fill once electricity and can travel 50 kilometers.
