Embodiment
Further understand and understanding for the juror is had architectural feature of the present utility model and the effect reached, sincerely help with preferred embodiment and cooperate detailed explanation, illustrate as after:
See also Fig. 2, it is the calcspar of a preferred embodiment of the present utility model.As shown in the figure, the voltage stabilizing circuit of automobile power source device of the present utility model comprises a Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10, a battery 20, switches circuit 25 and an electric capacity 40.Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 is when automobile starting, provide electrical power to the actuating unit of automobile and make automobile spare part and outfits such as engine oil spout computer, automobile audio, battery 20 is to be coupled to Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10, provide electrical power to Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 when making auto activation engine, Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 receives the electric power of battery, the magnitude of voltage of being given birth to when Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 then recharges voltage to battery 20 during greater than the electric power of battery 20, promptly is that battery 20 is charged.Wherein, battery 20 is an almost automobile battery, to discharge and recharge.
Electric capacity of voltage regulation 40 is coupled to battery 20, to stablize the output voltage of automobile power source device, because battery 20 starts the car engine except supplying, in the time of can also increasing power consumption in heavy duty (for example go up a slope, quicken suddenly), the compensation of can discharging, but light relies on the voltage regulation result of battery 20 itself very limited, because battery 20 inside are made up of many both positive and negative polarity lead flakes collocation electrolyte, the contact area of itself and electrolyte is little, and it is limited naturally to discharge and recharge usefulness.Just automobile in go up a slope, quicken suddenly or the state of running at high speed under, Blast Furnace Top Gas Recovery Turbine Unit (TRT) 10 is produced this moment moment electric power and pulse, be not sufficient in response to this a driving state down-firing coil and the required electric power of inductor, therefore can be by the electric power of electric capacity of voltage regulation 40 offset electricity generation devices 10 under above-mentioned driving situation, to promote the effect of voltage stabilizing.Wherein, electric capacity of voltage regulation 40 is a ultracapacitor, ultracapacitor is single capacitor, the capacitance of ultracapacitor can be up to more than the 1000000 μ F, and can discharge a large amount of electric currents, do not need capacitance is established and promoted to a plurality of ultracapacitors and connection, therefore the use of element of the present utility model is very few, so can reduce the fault probability of electric capacity of voltage regulation.
Wherein, commutation circuit 25 comprises that more a voltage sensing unit 30 and switches unit 50, voltage sensing unit 30 is parallel to the voltage of battery 20 with detecting battery 20, when the voltage of battery 20 then produces a sensing signal less than a threshold value, wherein, general battery 20 is under the situation that car engine starts, the voltage that battery 20 is provided is 13.5-14 volt (V), under the situation that car engine does not start, the voltage that battery 20 is provided is 12.5 volts, and therefore, we can be set at threshold value between the 12.8-13.2 volt, when the voltage of voltage sensing unit 30 detecting batteries 20 during, then produce the sensing signal less than threshold value.
Because electric capacity of voltage regulation 40 is coupled to battery 20 for a long time, and for a long time at auto activation engine and static and make electric capacity of voltage regulation 40 often carry out charge and discharge, electric capacity of voltage regulation 40 often is not discharged to 0 volt again, so can make electric capacity of voltage regulation 40 that the life-span of polarization phenomena and then shortening electric capacity of voltage regulation 40 takes place.Therefore, see also Fig. 3 and Fig. 4, it is the calcspar of another preferred embodiment of the present utility model.As shown in the figure, the voltage stabilizing circuit of automobile power source device of the present utility model is that in the difference of Fig. 2 embodiment voltage stabilizing circuit of the present utility model more comprises an arresting element in this embodiment, it couples between switch unit 50 and the electric capacity of voltage regulation 40, when voltage sensing unit 30 is lower than threshold value and switch unit 50 makes arresting element and electric capacity of voltage regulation 40 form a discharge loop.
Moreover, arresting element is an impedance component, as shown in Figure 3, be to use a resistance 60 as arresting element, when switch unit 50 in the voltage of battery 20 during less than threshold value, switch unit 50 is with switching circuit, make resistance 60 and electric capacity of voltage regulation 40 form discharge loop, with the discharge of the voltage instantaneous of electric capacity of voltage regulation 40 is 0 volt, so, can avoid electric capacity of voltage regulation 40 that polarization phenomena take place and shortens life-span of electric capacity of voltage regulation 40.In like manner, arresting element can be a light-emittingdiode 62 (Light Emitting Diode, LED), as shown in Figure 4, when light-emittingdiode 62 forms discharge loop with electric capacity of voltage regulation 40, electric capacity of voltage regulation 40 just can discharge by light-emittingdiode 62, and allows the user learn that electric capacity of voltage regulation 40 is discharging.
In addition, switch unit 50 can be a mechanical switch, similarly is relay (Relay), so with the loop between control electric capacity of voltage regulation 40 and the battery 20, when the voltage of battery 20 during less than threshold value, relay just can switch to discharge loop with the loop between electric capacity of voltage regulation 40 and the battery 20.
In sum; the voltage stabilizing circuit of automobile power source device of the present invention; its voltage that detects battery when the voltage sensing unit by switch unit is during less than threshold value; then make to form between electric capacity of voltage regulation and the battery and open circuit, so, can reduce the electric power of consuming cells; and can protect the life-span that electric capacity of voltage regulation makes increases electric capacity of voltage regulation; moreover the utility model more is provided with a discharge loop, to avoid the life-span of electric capacity of voltage regulation generation polarization phenomena and then increase electric capacity of voltage regulation.
The above, it only is a preferred embodiment of the present utility model, be not to be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the described shape of the utility model claim scope, structure, feature and spirit change and modify, and all should be included in the claim scope of the present utility model.
