Description

Electric boosted tandem bicycle

The utility model relates to bicycle, particularly a kind of electric boosted bicycle.

Existing bicycle, all be for single riding, it is simple in structure, easy to use, extremely welcome, but owing to be for single riding, two people have to a people be sitting on the shelf when going out together, and are very inconvenient, and power can not be provided, patent No. ZL92217588.8, the Chinese patent that name is called " two double driving bicycles " proposed a kind of have before, latter two seat, and double drive and can two people's bicycle driven that respectively trailing wheel driven of the chain that can be used on the vehicle frame both sides of two people on the seat of front and back, but this bicycle, when two people drive, because fitness is different from technology is different by bike, exerting oneself that healthy and technology are good is more, even equals a people and be with a people to ride, when particularly distance is far away, will feel to tire out.

The purpose of this utility model provides a kind ofly to be had electrically operatedly, can doublely drive again and the electric boosted tandem bicycle of double respectively manually driven.

The purpose of this utility model realizes by following technical scheme, electric boosted tandem bicycle has handlebar, vehicle frame, front seat, back vehicle seat, front-wheel, trailing wheel, left and right two flywheels on the trailing wheel, left and right chain and preceding wheel disc, rear trochal disc, it is characterized in that also having motor at the core of wheel, be fixed on the accumulate pond on the vehicle frame, manual mode controller and gauge panel, and the control circuit of control motor speed, said motor, the accumulate pond, manual mode controller is electrically connected between gauge panel and the control circuit.

Said control circuit is preferably based on the control circuit of pwm speed control system.

In the place ahead of back vehicle seat, rear bar can be housed.

This electric boosted tandem bicycle can also have solar panel, and cell panel is fixed on the vehicle frame, can open when preferably using.

Said motor in the wheel center part can be loaded on front-wheel or trailing wheel or front and back wheel and all be equipped with.

Below, in conjunction with the accompanying drawings and embodiments electric boosted tandem bicycle of the present utility model is explained in detail.

Fig. 1 is the front elevation of the electric boosted tandem bicycle of the utility model;

Fig. 2 is the top view of the electric boosted tandem bicycle of the utility model;

Fig. 3 is the top view of the electric boosted tandem bicycle of the utility model when solar panel opens when having solar panel;

Fig. 4 is the scheme drawing of the gauge panel of this electric boosted tandem bicycle;

Fig. 5 is the schematic circuit diagram of this electric boosted tandem bicycle.

As Fig. 1,2, electric boosted tandem bicycle of the present utility model has handlebar 1, vehicle frame 11, front seat 5, back vehicle seat 7, front-wheel 14, trailing wheel 8, have left and right two flywheels on the trailing wheel, be connected in preceding wheel disc 15 and the rear trochal disc 12 that is positioned under the vehicle seat of front and back with left and

right chain

9,10 respectively, during double riding, grasp direction of travel by the people who is positioned at front stall, two people scrunch simultaneously or a people scrunches and moves ahead, and are very convenient.At the core of front-wheel or trailing wheel one hub-type motor 15 (in case of necessity can front and back wheel all be equipped with) is housed, its shell (rotor) part links to each other with vehicle wheel spoke, stationary part then links to each other with vehicle frame with axletree, it is calculated that, this power of motor is 120 watts and gets final product, with direct current permanent magnetic hub-type electric machine is good, revolution is 150-200 rev/min, (this kind motor market is on sale), also has accumulate pond 4, manual mode controller 2 and gauge panel 3, said accumulate pond 4 is the energy of motor 15, for example can adopt 3 GP1270 type lead-acid batteries, parameter is 12V, 10 ampere-hours, or Ni-MH battery, parameter is 12V, 7 ampere-hours, it can be placed on the middle part of vehicle frame, also can be placed on the baggage rack or the both sides of baggage rack, said manual mode controller 2 preferably is loaded on the handlebar, so that operation, certainly also can be loaded on the appropriate position of vehicle frame, it is a slip switch, so that the bicyclist controls the rotating speed of motor 15 with the control speed of a motor vehicle, said gauge panel 3 has a shell and nixie display or other telltale with the voltage of demonstration battery and the electric current of circuit, charge where necessary so that understand battery status, gauge panel can be loaded on the handlebar, also can be loaded on the place that vehicle frame is conveniently seen, its scheme drawing as shown in Figure 4, gauge panel has a shell 18, be with key switch 19 in addition, voltage display 20 and Current Display 21, can place the circuit card and the element of circuit for controlling motor 16 in its housing, certainly circuit card and element also can be placed on other place, as the place ahead of handlebar etc., Fig. 5 shows the schematic circuit diagram of motor, its circuit for controlling motor 16 preferably utilizes pwm speed control system that motor speed is controlled, and the voltage of storage battery 4 is transported to gauge panel 3 and shown, electric current is transported to circuit for controlling motor 16 and transported to motor 15 through switch 19, manual mode controller control current amount, the magnitude of current are transported to gauge panel 3 simultaneously and are shown.

The place ahead at back vehicle seat 7 can have rear bar 6, as the handrail of the cyclist on the vehicle seat of back.

This bicycle can also adopt dual energy sources, promptly also has a solar panel 17, as shown in Figure 3, it can place on the shelf of bicycle, can open (collapsible) during use to both sides or extract (drawing and pulling type) out to increase light-receiving area, for example can adopt three of the plates of 520 * 260mm area, altogether 0.4m ², maximum 70 watts approximately of power, these solar panels can be to storage battery 4 chargings, and to increase the electric energy extending battery life of battery, Fig. 5 illustrates the connection location of solar panel 17 in circuit.

Electric boosted tandem bicycle of the present utility model is ridden conveniently, can a people scrunch walking, also can two people scrunch walking, go back useable electric moter and be the power walking, very flexible, for outing, travelling, exercise, and the riding instead of walk of city traffic, all very suitable, be a kind of novel, energy-conservation, free of contamination running vehicle.
