Description
Technical field
The utility model relates to a kind of distance increasing unit.
Background technology
At present; Because battery capacity restriction; The pure electric vehicle mileage of generally continuing a journey is short partially; Can not satisfy part user's demand, so rise a kind of whole range electric vehicle in the electro-tricycle field, this extended-range electric vehicle is on common electro-tricycle basis, to increase a kind of fuel oil generating and control device.This device implementation process is: in the car load driving process, battery does not have electricity or power shortage when causing brownout, and the apparatus control portion branch will start fuel electric generator, and fuel electric generator is that car load provides electric energy in real time, realizes that electro-tricycle increases the purpose of continuation of the journey mileage.This device has increased the continuation of the journey mileage of electric motor car again owing to possess automatic controlled function, praises highly the acceptance by users so receive market, and the batch that has formed certain scale is at present sold.But; Equally also there is certain defective in this device: (1) this extended-range device cost is generally higher; One of subjective purpose that present user selects electro-tricycle can be practiced thrift cost than fuel vehicle exactly, it is reported that this device accounts for 20% of electro-tricycle integral vehicle cost, and control section cost height is a main cause; Though convenient, also increased disposable input with the user.(2) this extended-range device control module part is damaged easily, and repair rate is higher; Main cause is: controller is mainly formed components and parts metal-oxide-semiconductor withstand voltage generally not high (tricycle does not surpass 100V with majority); In case battery or car load circuit are loosening in the running; Load is laid down suddenly, will cause generating voltage to jump and punctures metal-oxide-semiconductor, causes device to damage and loses efficacy.(3) this device power generation part be prone to lose efficacy, and concrete reason is a power generation part in order to realize that volume is little and efficient is high, was commonly permanent magnetic brushless; The generating waveform approaches the dextrorotation ripple when work; When generating state was in trough, voltage was lower than cell voltage, battery current can occur and pour in down a chimney to generator; Thereby cause the magnetic shoe demagnetization, power of motor slackens gradually and lost efficacy.
The utility model content
The purpose of the utility model provides a kind of simple in structure, need not the generating rectifier type distance increasing unit device
of nonshared control unit.
To achieve these goals, adopt following technical scheme:
A kind of generating rectifier type distance increasing unit device; Comprise the generator that is connected with engine; Generator links to each other with rectification module, and the direct current that the process rectification module obtains is respectively storage battery and drive motor controller provides electric power, and it is characterized in that: said generator is provided with the hand pull starting-up device.
As further optimization, the startup of engine for ease, said device also is provided for the starter motor of ato unit, and wherein starter motor provides electric power by storage battery.
Said rectification module comprises the branch road of three parallel connections, is in series with two end to end diodes on every branch road, and wherein the three-phase output end of generator is connected to respectively between two diodes.
For the ease of the heat radiation of rectification module, said rectification module is provided with radiating block.
The utility model is simple in structure, when continuing extended-range device on the market and increase the function of electric three-wheel continuation of the journey mileage, has lower failure rate and more excellent cost performance; Since rectifier bridge diode self to conducting another on state characteristic not; When generating voltage is in sinusoidal wave trough; Electric current battery current will can not occur and pour in down a chimney entering motor phenomenon, also can not cause the magnetic shoe demagnetization, so can solve the phenomenon that present distance increasing unit device magnetic shoe is prone to demagnetization.Rectification module is to be made up of crystal diode, and its withstand voltage is tens of times of metal-oxide-semiconductor, will thoroughly solve the existing market electronic extended-range device of three-wheel and unload back voltage rising suddenly and puncture controller failure, and price is cheaper.
Description of drawings
Fig. 1 is the electrical schematic diagram of the utility model;
Fig. 2 is the physical circuit figure of rectification module among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be further described.
As shown in Figure 1, a kind of fuel oil generating rectifier type distance increasing unit device, mainly comprise: the rectification module that the generator that is connected with engine, hand pull starting-up device, starter motor are connected with generator, the rectifier bridge module is equipped with radiating block.Rectification module is connected with radiating block through mechanical systems such as bolts, and faying face scribbles heat radiation fat, is convenient to heat radiation and disassembles repair and replacement; The blanket of engine is made up of machine oil alarm, ground strap, igniter and flameout switch.
Starter motor or hand pull starting-up device all can be lighted fuel engines; Radiating block is contacted with vent position with the car load vehicle frame simultaneously; Blanket can be realized manually flame-out and two kinds of flame-out modes of auto extinguishing.The starter motor specification is for can adopt the 12V direct current machine, and Starting mode is that gears engaged drives a bent axle rotation combustion; Its output shaft stabilization of speed of the logical machine of the common use fuel oil that engine can be, output speed is the fixed range value.
When carrying the electric motor car work of this distance increasing unit device, open battery switch, drive motor controller is in running order; Rotate handle and make drive motor controller collect the handle signal, and then the controlling and driving machine operation, car load is gone; In the process of moving, battery power consumption, the car load speed of a motor vehicle reduces; When the speed of a motor vehicle can't satisfy when driver requested, the driver pulls and starts or electricity starts and sends out a burn engine, engine drives generator for electricity generation; Rectification is a direct current energy to the electricity that sends through rectification module, and electric energy input drive motor controller guarantees that car load continues cruising.
In the process of moving, the car load consumed power changes with road condition change, and under the less situation of descending even load, unnecessary direct current energy can also be stored to storage battery; When the needs that arrive at the destination are flame-out, be flame-out through the blanket button control.
