Description

Battery bag starts and ignition engine

Technical field

This utility model relates to a kind of internal combustion engine (ICE), particularly relates to a kind of battery bag and starts and ignition engine, and this draws Hold up and can be fought startup by the power supply point that external cell provides, can be applicable to various outdoor garden equipment such as grass-mowing machine, brush cutter, Hay mover, shrub and hedge trimmer, chain saw, cutting machine, electromotor, jetting machine, water pump, etc..

Background technology

Tradition hand pull starting-up engine, produces rotary power when repeatedly pulling " flywheel " by handle, drives engine.Simultaneously " flywheel " rotates around " lighter ", produces electric energy by coil generating, then produces spark ignition；Its existing problems are as follows: 1) relatively difficult startup, if pulling force is inadequate, or pulling rate is inadequate, and engine can not reach starting speed, and engine just cannot start, even if Pulling force pulling rate enough in the case of, engine rise initial several circles of turning can not normal ignition because initial rotating speed is relatively low, it is impossible to Produce enough igniting electric energy, therefore light a fire and limited by minimum speed.2) ignition angle rises at engine and turns the stage and all cannot Dynamically change, because engine rises, to turn stage rotating speed relatively low, it is impossible to produces enough stable electric energy so that CDI unit (i.e. compares Unit) ignition angle that calculates not in best angle position, engine start can still relative difficulty, need to rotate relatively Could start after many number of turns.3) high voltage package generating needs to consume a part of power of engine, conventional engine effective output Relatively lower.

Conventional batteries bag starts engine, supplies electricity to, by external power source-battery, " electric starter " that " motor " drives, and produces Rotary power, drives engine, and " flywheel " rotates around " lighter " simultaneously, produces electric energy by coil generating, then produces electricity fire Spark ignition, conventional batteries bag starts formula engine and overcomes (1st) some drawback of hand-pulling engine, i.e. avoids when pulling pulling force not Enough, or pulling rate is inadequate；But rear 2 problems still exist, because battery bag is only powered to starter motor, do not give high voltage package direct Power supply, high voltage package oneself can not produce enough, stable electric energy when engine rises and turns, it is impossible to adjusts the angle of ignition at start-up period Degree.

To sum up, current existing engine either hand pull starting-up, or electric motor starting, flywheel send out around lighter rotation Electricity produces electric energy, and during engine start, ignition location-angle immobilizes, and flywheel operating simultaneously also increases engine Load, cannot provide stable voltage, engine start difficulty when engine start.

Utility model content

The purpose of this utility model is to provide a kind of engine can easily start and light a fire the electricity not limited by minimum speed Chi Bao starts and ignition engine.

Battery bag of the present utility model starts and ignition engine, including electric starter, comparing unit, lighter, flywheel, electricity Pond；Described electric starter includes motor, gear train, spring, driving dish, and motor makes spring energy-storage, bullet by gear train Rotation is transferred to driving dish by spring, drives dribbling to move flywheel turns；It is fixed with Magnet on described flywheel, lighter is fixed with Hall element, detection signal is transmitted to comparing unit by Hall element, and described battery is powered to motor, the most also gives point Firearm is powered.

The beneficial effects of the utility model are:

This utility model uses external power source-battery to provide electric energy for motor and lighter simultaneously, and engine can easy quilt Electric motor starting；During engine start and operating, the Magnet being arranged on flywheel and the Hall being arranged on lighter pass Sensor produces Hall effect, it is thus achieved that the position-angle of igniting and engine speed information；According to engine turned position-angle information Send ignition signal, therefore light a fire and do not limited by minimum speed, start just may be used from flywheel turns first lap under any rotating speed With normal ignition, lighter can automatically adjust the position-angle of igniting according to engine speed information, and flywheel is mutual with lighter Rotate but no longer generate electricity and produce electric energy, it is to avoid bringing extra load to engine, the burning voltage of battery output is that engine is fast Speed starts and even running provides safeguard.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described further.

Battery bag of the present utility model starts and ignition engine can be fought startup by the power supply point that external cell provides, can It is applied to various outdoor garden equipment such as grass-mowing machine, brush cutter, hay mover, shrub and hedge trimmer, chain saw, cutting machine, electromotor, high pressure clear Washing machine, water pump, etc..This utility model is further elaborated as a example by engine grass-mowing machine by this example.

As shown in figs 1-9, this engine grass-mowing machine includes electric starter 2, lighter 3, flywheel 10, battery 4；Battery 4 is installed On battery holder 7, battery holder 7 is fixed on grass-mowing machine take-off lever 1 by retainer ring 9, and grass-mowing machine is provided with on and off switch 6 and opens Dynamic button 5, described electric starter 2 provides rotary power for engine, is arranged in casing 2-1 as in figure 2 it is shown, specifically include Motor 2-7, gear train are (by the driving gear 2-2 coaxial with motor output shaft, travelling gear 2-5, driven gear 2-8 structure Become), spring 2-3, driving dish 2-4, motor 2-7 is externally provided with motor case 2-6, presses start button 5, and electricity given by described battery 4 Machine 2-7 powers, electric machine rotation, and by gear train, slows down and increase torsion simultaneously, makes the tension of spring 2-3 axial rotary store Can, rotation is transferred to driving dish 2-4 by spring 2-3, and driving dish 2-4 flywheel driven 10 rotates；After on and off switch 6 is opened, battery 4 Power to lighter 3 (i.e. spark plug) simultaneously, described flywheel 10 is fixed with Magnet 10-1, lighter 3 is fixed with Hall Sensor (i.e. induction apparatus), the flywheel of rotation i.e. produces Hall effect, the anglec of rotation of detecting and alarm bent axle with Hall element And rotary speed information, the transmission of detection information is compared by Hall element 11 to comparing unit (i.e. CDI unit in conventional engine) 12 Calculating, obtain the signal of optimal ignition location-angle, it is engine point that lighter produces pulse electric spark after obtaining ignition signal Fire, comparing unit calculates and controls what igniter fire was known to the skilled person after obtaining ignition signal, its a kind of control Circuit can be as shown in Figure 8.Ignition location-angle is starting beginning just along with the change of rotating speed changes, whole startup and operating thereof During control between 15 ° to 30 °, with ensure engine safe speed of rotation scope operate.This engine can under any rotating speed from Flywheel turns first lap starts just can therefore to light a fire do not limited by rotating speed with normal ignition.

Because Hall effect, while the position-angle of detecting and alarm igniting, obtain the information of engine speed, lighter 3 Position-the angle of igniting is adjusted, to reach the position-angle of optimal igniting, the position-angle therefore lighted a fire according to engine speed Degree changes according to the rotation speed change of engine, as it is shown in figure 9, when rotating speed is less than 3500 turns, ignition location-angle arrives at 15 ° 30 ° of changes are to reach optimal starting ignition position-angle.When rotating speed exceedes safety value, ignition location-angle is adjusted again It is whole, within rotating speed returns to safe limit value the most therewith.

By above-mentioned design, engine grass-mowing machine can realize rapid-ignition, then safety, even running.
