Description
Technical field
The utility model relates to a kind of battery-driven car, is concretely to produce the battery-driven car of braking about a kind of generating by electrical generator.
Background technology
Now because the problem of discharging and noise etc., adding that urban is limit rubs, so that battery-driven car is able to a large amount of development, present battery-driven car is because simple in structure, perhaps use the brake structure of bicycle or motor bike, come battery-driven car is carried out braking in necessary situation, because battery-driven car can be wasted the part electric weight in braking procedure, this battery-driven car to reserve of electricity deficiency own is disadvantageous.In order the electric energy of brake portion loss to be retrieved also for so that the travelled distance of battery-driven car can be far away, be necessary the stop mechanism of existing battery-driven car is improved.
In view of above situation, be necessary the braking structure of existing battery-driven car is improved, reach the purpose that overcomes the above problems.
Summary of the invention
The purpose of this utility model provides a kind of battery-driven car, solves the problem of the electric weight waste of existing battery-driven car in braking procedure; Used so that in braking, the part electric weight can store, increase the travelled distance of battery-driven car.
The utility model is a kind of battery-driven car, comprise electrical generator, motor and storage battery, described storage battery is electrically connected with motor, electrical generator is connected with storage battery, it is characterized in that: described electrical generator links to each other with the battery-driven car axle drive shaft, at electromobile frame mechanical brake device is set, is provided with switch between described electrical generator and the storage battery.The technical program can make the middle electrical generator that travels in the battery-driven car not generate electricity, can not produce any resistance, when braking, electrical generator is communicated with storage battery, give electric current of electrical generator, produce magnetic field, coherence when travelling and the speed electric DC of speed unit brush electrical motor send alternating current to carry out load short circuits or carries out second diffluence to battery; The resistance that utilizes cutting magnetic field to produce reaches mother's that axle drive shaft slows down, simultaneously can also make the electricity of generation be stored in storage battery by electrical connection, charge a battery, thereby prolong the travelled distance of battery-driven car, and reduced the rate of braking of the mechanical braking of battery-driven car, prolong the life-span of mechanical braking, charged the battery to reach quick purpose without braking by braking to generate electricity.
Further, the axle of described electrical generator is the axle drive shaft of battery-driven car, and the stator of electrical generator is fixed on the electromobile frame.Can reach simple in structure, effective purpose by this structure.
Further, it is other that described stator is fixed on the electric motor car mechanical braking.This structure is convenient to install, maintenance.
Further, described switch is controlled by brake equipment.Simple by this programme, fully travelling makes electrical generator reach the purpose of auxiliary braking in braking procedure.
Beneficial effect
The beneficial effects of the utility model are to improve and being connected of electrical generator and axle drive shaft by the driver train to battery-driven car, in the situation of the mechanical braking intensity that has reduced battery-driven car, reach the purpose of auxiliary braking and charging by power generation assembly.This is simple and practical, and braking effect is good.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
The utility model is a kind of electric vehicle structure schematic diagram, comprise as shown in the figure electrical generator 1, motor 2 and storage battery 3, described storage battery 3 is electrically connected with motor 2, electrical generator 1 is electrically connected with storage battery 3, described electrical generator 1 links to each other with battery-driven car axle drive shaft 4, at this battery-driven car axle drive shaft mechanical brake device 5 is set, simultaneously between electrical generator and storage battery, be provided with switch, electrical generator does not produce any electricity in battery-driven car travels, because only in the situation that energising just can produce the magnetic field generation current, increase simultaneously magnetic field force between the stator of electrical generator and the rotor.Therefore, control Push And Release between electrical generator and the storage battery by brake equipment, come so that whether electrical generator should generate electricity.When battery-driven car needed to brake under steam, the crawl brake equipment was switched between electrical generator and the storage battery, made electrical generator produce magnetic field, produced resistance, carried out auxiliary braking; Simultaneously the electric power that produces is got up by battery stores; Reach and to store again because of the electric power that braking occurs because of the electricity of braking waste.Thereby prolong the travelled distance of battery-driven car.
The rotor shaft of the described electrical generator of the present embodiment is the axle drive shaft 4 of battery-driven car, and the stator 6 of electrical generator is fixed on the electromobile frame.
In the present embodiment, electric vehicle hub 11 left sides are provided with brake equipment 5 in the accompanying drawing, on brake equipment 5 next doors and be fixed on stator 6 on the vehicle frame.
In the present embodiment, switch is by reaching the through and off between UNICOM's electrical generator and the storage battery in the control brake equipment.Simple for structure.
Work of the present utility model is such: battery-driven car is in the process of moving in the needs braking, coherence when utilizing brake and the speed of speed driving direct current unit's brush electrical motor (also being a dynamo generator) send alternating current to carry out load short circuits or carries out second diffluence to battery, (battery is carried out halves separately) charges the battery to reach quick without braking, but the dead car of can not stopping, in the situation that the faster braking effect of battery-driven car is more obvious, because speed is faster, cutting magnetic field is just faster, resistance is larger, increases the service life thereby original machinery is stopped.Thereby the electricity that battery-driven car is sent when brake returns battery again, re-uses again, and electricity is increased on original distance travelled to some extent.
Battery-driven car in the present embodiment can be four-wheeled, and three-wheel vehicle also can make two-wheel car, just simply adjusts as required and can change utilization to this structure.
Need to prove: above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
