As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature:
Described may command increasing apparatus is a device that is connected to transistor device for power switching and booster circuit, by transistor device for power switching PWM pulse width modulation controlled electrical generator outgoing current, and ultracapacitor is charged by boosting circuit boosts voltage, electrical generator outgoing current size has determined the size of braking force, owing to be dynamic brake, movable parts that can stuck vehicle, the locking wheel causes the driving get out of hand.
Described ultracapacitor can large current charge, even emergency brake, the may command increasing apparatus also can be converted into the electric energy of electrical generator rapidly to the ultracapacitor rechargeable energy, discharge the kinetic energy of vehicle, because the ultracapacitor capacitance is big, can store bigger energy, be exactly emergency brake, also can in time store the energy of electrical generator.
Described battery charger is a wide-voltage switch power supply that the electric charge with ultracapacitor is a power supply, according to the suitable electric current of battery pack mode control to batteries charging, if battery is full of, SELF CL battery charger, protection battery.
Described controollable electric discharge device is a device of being made up of transistor power device and discharging resistance, in case the voltage of ultracapacitor surpasses certain value, and the conducting of control transistor power device, by conductive discharge, the protection ultracapacitor.
Use the present invention can reach following beneficial effect: by the vehicle dynamic brake device of this structure; the size of car brakeing can be controlled; the electric energy that braking is sent reclaims to greatest extent; even the speed of vehicle is very slow; the voltage that electrical generator sends is very low; also can boost ultracapacitor is charged by capacitor charger; the energy of storage electrical generator; emergency brake when if car speed is very fast; also can store the energy of electrical generator by the fast speed charging of ultracapacitor; control rationally is to the charging of battery pack, and the protection battery pack can be not excessive because of charging current, overshoot electricity and damaging.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention.
1, may command increasing apparatus, 2, ultracapacitor, 3, battery charger, 4, electric discharge device, 5, battery pack, 6, brake sensor, G is an electrical generator, MCU is a microprocessor.
Five, the specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
As shown in Figure 1, the present invention includes motor, may command increasing apparatus 1, ultracapacitor 2, battery charger 3, electric discharge device 4, battery pack 5, microprocessor and brake sensor 6, motor and vehicle wheel, the movable parts of vehicles such as transmission shaft connects, may command increasing apparatus 1 is electrically connected with motor, ultracapacitor 2 is electrically connected with may command increasing apparatus 1, the size of current of may command increasing apparatus 1 control motor output and the charging valtage of ultracapacitor 2, ultracapacitor 2 is connected on the battery charger 3, and ultracapacitor 2 also is connected with a controollable electric discharge device 4; May command increasing apparatus 1, battery charger 3 and electric discharge device 4 all are connected with microprocessor signals, microprocessor also is connected to brake sensor 6, the signal of brake driver action is input to microprocessor by brake sensor 6, and the electric current of controlling controlled increasing apparatus 1 changes.
Working process of the present invention: when normal vehicle operation, do not have brake signal, may command increasing apparatus 1 is not worked, and does not work in other unit.When brake driver, brake sensor 6 is input to microprocessor to the signal of brake size, microprocessor is according to brake signal 6 and 2 chargings of 1 pair of ultracapacitor of Vehicle Speed signal control may command increasing apparatus, the size of electrical generator outgoing current has determined the generated output power size, also determined the size of braking force, when brake signal was big, electric current was big, and braking force is just big.In case ultracapacitor 2 has electric weight, battery charger 3 is a power supply with the electric weight of ultracapacitor 2 just, controlling suitable charging current starts working battery pack 5 is charged, if the electric weight of battery pack 5 is full of, meeting SELF CL battery charger 3, if the voltage of ultracapacitor 2 arrives certain value to height, controlled discharge device 4 is by the conducting of internal transistor power device, by conductive discharge, discharge the electric charge on the ultracapacitor 2.Because vehicle braked is to be produced by generating, thus in case vehicle stops, just there is not braking force, so suggestion of this device and mechanical brake use together.Mechanical brake is started working when adjusting brake pedal or handle 1/2 to 2/3 traverse, and through stepping on braking vane or flicking handle, by apparatus of the present invention braking, recuperated energy, vehicle stopped the back and passed through by mechanical brake, keep vehicle-state when vehicle need slow down.Worked simultaneously by this device and mechanical brake during emergency brake, suitably recuperated energy improves braking effect.In sum, the present invention is a kind of generator for electricity generation of passing through, control capacitor ultracapacitor and battery charge reach the adjusting generated output, the Vehicular brake device of control brake and battery charge, be specially adapted to vehicles such as electronlmobil, fuel and electric hybrid car and battery-operated motor cycle and use, also be fit to other vehicles and use.
