The utility model provides a vehicle-mounted audio system with a battery power alarm function. The vehicle-mounted audio system comprises a vehicle-mounted audio body which further comprises a voltage detection circuit, an audio main control circuit, an audio display circuit and an alarm circuit. The voltage detection circuit and the audio main control circuit are connected sequentially in order, the audio main control circuit is respectively connected with the audio display circuit and the alarm circuit, and the voltage detection circuit is connected with an external vehicle-mounted battery. The vehicle-mounted audio system is simple in structure, low in cost, and a user does not need to buy a battery power monitoring device; and further, the vehicle-mounted audio system has an alarm function and a function of automatically shutting down the audio.
Description
Technical field
The utility model belongs to vehicle electric field, especially relates to a kind of vehicle audio that comprises storage battery electric weight warning function.
Background technology
Haze weather takes place frequently recently, news report is often arranged because the highway sealing is listened to vehicle audio when the driver waits for for a long time in car, causes the storage battery electric weight to use up, thus the situation that can't start up the car.
We are in traffic congestion or the situation of listening to sound equipment after flame-out is also often arranged when waiting the people at ordinary times, and particularly aging at storage battery because sound equipment is the assembly of main consume electric power on the automobile, during the performance reduction, the risk that above-mentioned storage battery electric weight is used up is particularly evident.
The technical scheme of prior art:
1, also have other external equipments can show battery voltage (for example, the device that is connected on the cigar lighter being arranged), but need to buy separately, cost is higher, uses complicated, not attractive in appearance;
2, only can show output voltage values.
The shortcoming of prior art:
1, the user must could understand storage battery electric weight (for example, the device that is connected on the cigar lighter being arranged) by buying other external equipments, and cost is higher, uses complicated, not attractive in appearance;
2, this kind device only can show battery voltage, for some new hand drivers who does not understand the automobile operation principle, does not know how to tackle, do not have the effect of caution;
3, power consumer apparatus can not be closed automatically, as sound equipment.
Summary of the invention
At the deficiencies in the prior art, the utility model merges storage battery electric weight alarm function to be realized in automobile audio, points out to user speech when electric weight is not enough, tells that clearly how the user should tackle, and also can realize closing automatically sound equipment, saves energy.The risk that reduction can't start up the car.
The technical solution of the utility model is:
A kind of vehicle audio that comprises storage battery electric weight warning function, comprise the vehicle audio body, also comprise voltage detecting circuit, sound equipment main control circuit, sound equipment display circuit and warning circuit in the described vehicle audio body, described voltage detecting circuit, sound equipment main control circuit are linked in sequence successively, described sound equipment main control circuit is connected with warning circuit with described sound equipment display circuit respectively, and described voltage detecting circuit is connected with outside vehicular power-bottle.
Described warning circuit comprises a kind of in sound light alarming circuit, voice cue module or the buzzer.
Described sound equipment main control circuit also links to each other with the sound equipment control switch.
Described sound equipment display circuit comprises LED or LCD display.
Advantage and the good effect that the utlity model has are:
1. simple in structure, cost is low, and the user need not to buy separately storage battery electric quantity monitoring equipment;
2. the utility model not only can show battery voltage, also has the warning reminding function simultaneously;
3. the utility model also has the function of closing sound equipment automatically.
Description of drawings
Fig. 1 is internal circuit configuration schematic diagram of the present utility model
Embodiment
With reference to the accompanying drawings execution mode of the present utility model is described in detail below:
As shown in Figure 1, a kind of vehicle audio that comprises storage battery electric weight warning function, comprise the vehicle audio body, also comprise voltage detecting circuit, sound equipment main control circuit, sound equipment display circuit and warning circuit in the described vehicle audio body, described voltage detecting circuit, sound equipment main control circuit are linked in sequence successively, described sound equipment main control circuit is connected with warning circuit with described sound equipment display circuit respectively, and described voltage detecting circuit is connected with outside vehicular power-bottle.Because adopt technique scheme, the utility model is simple in structure, cost is low, and the user need not to buy separately storage battery electric quantity monitoring equipment; The utility model not only has the battery voltage Presentation Function, also has the warning reminding function simultaneously.
Report to the police or voice prompting function for reaching, warning circuit comprises a kind of in sound light alarming circuit, voice cue module (typing anthropomorphic dummy's alarm sound in advance) or the buzzer.Buzzer also can select for use car horn to realize.
In the present embodiment, the sound equipment main control circuit also links to each other with the sound equipment control switch.When battery voltage reached alarming line, the sound equipment main control circuit can be controlled Stereo Switch and close, and then reached the saving electric energy, avoided the storage battery electric weight to exhaust, and the phenomenon that automobile can't be struck sparks takes place.
In the present embodiment, the sound equipment display circuit comprises LED or LCD display.
Operation principle of the present utility model: the dump energy of storage battery is more low, and its output voltage is also more low.By the monitoring to the battery voltage value, can understand the dump energy of storage battery.
The storage battery output is guided to voltage detecting circuit, voltage detecting circuit inputs to detected voltage signal the processor of sound equipment main control circuit and reminds voltage (can adjust according to different vehicles and storage battery situation with reference to reminding voltage) to compare with the reference of setting, when arriving with reference to the prompting magnitude of voltage, will send the prompting of voice or sound and light alarm; The processor of sound equipment main control circuit also can be sent to the output voltage of storage battery on the display screen in the sound equipment display circuit and show; The processor of while sound equipment main control circuit also can control the sound equipment control switch and cut out automatically.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
