Abstract
A voltage and water-temperature sensing alarm for automobile, which comprises a voltage sensing circuit, a water-temperature sensing circuit, and a warning circuit, wherein the voltage sensing circuit is connected with the storage battery of cars, which can sense high and low voltages of the storage battery. A signal is delivered when the voltage is lower than the set value. A water-temperature sensing device in the water-temperature sensing circuit is installed on the cooling tank, and a signal is delivered when the water temperature is surpassed the set value. The warning circuit is connected with the voltage sensing circuit and water-temperature sensing circuit. With the structure, when the voltage of storage battery is lower than the set value or the water temperature is surpassed the set value, the warning circuit delivers the signal to inform drivers, which avoids damage engines due to overheating, and not start cars.
Description
Technical field
The utility model relates to alarm buzzer, especially a kind of voltage of automobile and water temperature sensing alarm buzzer, can detect the water temperature of the voltage and the cooling water tank of automobile storage battery, the water temperature that can be lower than setting value or cooling water tank in the voltage of the storage battery signal that gives a warning when surpassing setting value is informed motorist, to avoid causing engine to cross the situation that cause thermal damage maybe can't start up the car.
Background technique
Press, when general motorist is driven, after starting car, promptly drive usually to leave away; And when starting up the car, if during the situation that takes place to start the engine, then might be run out of gas, the electric energy of storage battery is lower than the energy of startup, engine is crossed the various situations of cause thermal damage or the like.
During automobile is advanced again,, be that the overheated or oil plant of engine exhausts or the like situation usually if just in case when flame-out situation takes place; Or the overlong time of automobile parking or car often open short distance, makes the electric energy of storage battery be lower than the energy of startup, and cause the situation that can't start up the car after the parking.
And motorist is before driving or automobile when advancing, if when above-mentioned condition takes place, except the electric energy of storage battery can't by on the instrument panel as can be known, all the other are as the water temperature of oil mass and cooling water tank, can be by the oil gauge on the instrument panel and thermometer as can be known.
But general motorist notes the oil gauge except meeting, and all the other then not too can note as water-thermometer, therefore when driving, if when the water temperature of cooling water tank is too high, then can cause engine overheated and damage.Using when the storage battery of automobile starts engine except supplying with again, all the other also are to use the electric energy of storage battery as headlight, indicator, sound equipment, rain brush or the like; Therefore under situation about not starting the engine,, then may make the electric energy of storage battery reduce, and cause the situation that can't start the engine if use the electric energy of storage battery.
In addition,, but the electric power storage ability of storage battery is reduced, in the time of after parking, will restarting engine equally, because of the electric power storage power of storage battery reduces the situation that causes brownout to start the engine if do not pay attention to maintenance usually.
Summary of the invention
Usually very can not note the water temperature of the voltage and the cooling water tank of storage battery in view of motorist, when making the situation that automobile just in case take place can't start, cause engine to damage or the air conditioner damaged condition in succession, thereby increase the expense of auto repair; Special voltage and the water temperature sensing alarm buzzer that proposes a kind of automobile.
Main purpose of the present utility model, aim to provide the alarm buzzer of the water temperature of a kind of voltage that can detect automobile storage battery and cooling water tank, the water temperature that can be lower than setting value or cooling water tank in the voltage of storage battery surpasses setting value, the signal that promptly gives a warning is informed motorist, to avoid causing engine to cross the situation that cause thermal damage maybe can't start up the car.
Voltage of the present utility model and water temperature sensing alarm buzzer are made up of voltage sensing circuit, water temperature sensing circuit and alarm circuit, wherein this voltage sensing circuit connects the storage battery of automobile, but and the voltage of this voltage sensing circuit sensing storage battery height, if voltage is lower than setting value and then sends a signal; This water temperature sensing circuit has a temperature-sensitive sticker that is installed in the cooling water tank of automobile again, then sends a signal if the water temperature of the cooling water tank of automobile surpasses setting value; This alarm circuit connects voltage sensing circuit and water temperature sensing circuit in addition; According to above-mentioned structure, if being lower than the water temperature of setting value or cooling water tank, the voltage of storage battery surpasses setting value, this alarm circuit signal that promptly gives a warning is informed motorist, to avoid causing engine to cross the situation that cause thermal damage maybe can't start up the car.
Description of drawings Fig. 1 is a circuit diagram of the present utility model.
Embodiment
At first, see also Fig. 1, the utility model by voltage sensing circuit 1, water temperature sensing circuit 2, and alarm circuit 3 form, now that the effect and the annexation division of each circuit is as follows:
Water temperature sensing circuit 2, it also connects voltage sensing circuit 1, this water temperature sensing circuit 2 has the temperature-sensitive sticker 21 of a cooling water tank that is installed in automobile (expression in graphic), and this water temperature sensing circuit 2 has temperature setting button 22a, 22b that all right one way or the other power transformation resistance is formed, can set button 22a, 22b by two temperatures and set degree of detecing temperature range, then send a signal if the water temperature of the cooling water tank of automobile surpasses setting value;
According to above-mentioned structure, because this voltage sensing circuit 1 connects the storage battery of automobile, if the voltage of storage battery is a little less than engine start voltage but its electric power still can start engine the time, then this voltage sensing circuit 1 can be sent a signal, this alarm circuit 3 one receives that this signal can send alert news and inform motorist, and so motorist can be avoided the situation that the power shortage because of storage battery can't start the engine.
Moreover, the temperature-sensitive sticker 21 of this water temperature sensing circuit 2 can the sensing automobile the temperature of cooling water tank, when if the water temperature of the cooling water tank of automobile is too high, then this water temperature sensing circuit 2 can be sent a signal to alarm circuit 3, this alarm circuit 3 one receives that this signal can send alert news and inform that the water temperature of this cooling water tank of motorist is too high, must cool off immediately, so can avoid damaging or situation that cold air damages because of engine is overheated.
This water temperature sensing circuit 2 can be set button 22a and 22b setting temperature by two temperatures again, and two temperatures is set button 22a and 22b system sets in order to coarse adjustment and fine setting temperature respectively, sets with the chilling temperature that adapts to different label car moneys.
In addition, this alarm circuit 3 can be a buzzer, reminds motorist and can directly send the sound by this buzzer; Or this alarm circuit 3 can be a voice IC and connects amplification circuit and loudspeaker (expression in graphic), and these voice IC can be amplified speech sound signal via amplification circuit, plays voice by loudspeaker again, and mode that so promptly can voice is reminded motorist; This is another enforcement of the present utility model, and reference is provided.
