Summary of the invention
The utility model is followed the low-carbon (LC) theme just, from the angle of energy savings, has designed a Vehicular solar fan that the function of enjoying the cool is provided for passenger in the car.
Vehicular solar fan described in the utility model mainly comprises: comprise solar panel, charge circuit, storage battery, the feed circuit that are installed in roof and be installed in the interior fan of car; Solar panel is connected with storage battery by charge circuit, and storage battery is connected with fan by feed circuit again.
During use, the solar panel that is installed in roof is exposed to sunlight and luminous energy is converted into electric energy, is stored in the storage battery, is used for drive fan afterwards to rotate.
Preferably, set up a protective circuit in parallel with storage battery that plays over-charge protective and the effect of load overvoltage protection that prevents that storage battery from overcharging, this technology belongs to prior art, no longer too much describes here.
For storage battery, a suitable charging method and a guard method is arranged, not only help the rational Application of fan, and can prolong the service life of battery.For load, if the voltage of load is excessive, circuital current increases, and will make circuit produce huge heat, even burn circuit; If voltage is too little, then can not drive load, make the load cisco unity malfunction.Protective circuit is connected in parallel on the two ends of storage battery, prevents the over-charge protective that overcharges of lithium cell and the overvoltage protection of load.
The installation of fan is preferably to be embedded in the car inner top, and the passenger can open fan according to the needs of oneself, also can be by touching the rotation that electric fan stops fan.
As another mode, an anti-electric current is poured in down a chimney diode be arranged between solar panel and the storage battery, pour in down a chimney diode by anti-electric current solar panel and storage battery are directly linked to each other with charging.
In addition, one and storage battery bonded assembly electricity driving radiator can be set winter, and electricity drives radiator and is arranged on the fan front portion, charges a battery by solar panel, storage battery drives electricity and drives radiator heat-dissipation, drives fan simultaneously and revolves Homogeneouslly-radiating in the bogie car at a slow speed.
The beneficial effects of the utility model are: solar power be the most direct on the earth, the most general also be the energy that cleans most, have at realm of nature again simultaneously and constantly generate, and obtain clocklike the characteristics of replenishing, the utility model utilizes inexhaustible, nexhaustible solar power comes drive fan, be applied on the bus practicality, environmental protection, low-carbon (LC).Can allow the passenger in the sultry bus in summer, enjoy the slight chill in the air of silk silk.
The specific embodiment
Embodiment 1
As shown in Figure 1, the Vehicular solar fan mainly comprises solar panel, charge circuit, storage battery, the feed circuit that are installed in the bus top and is installed in the interior fan of bus.Solar panel is connected with storage battery by charge circuit, and storage battery is connected with fan by feed circuit again.During use, the solar panel that is installed in the bus top is exposed to sunlight and luminous energy is converted into electric energy, is stored in the storage battery, is used for drive fan afterwards to rotate.Set up a protective circuit in parallel that plays over-charge protective and the effect of load overvoltage protection that prevents that storage battery from overcharging with storage battery.
Embodiment 2
Solar panel pours in down a chimney diode by anti-electric current solar panel and storage battery is directly linked to each other with charging.Other are with embodiment 1.
With the solar panel output voltage is 5.5v, power is to count about 0.45W, if lithium cell (storage battery) minimum voltage 3.07v in the utility model circuit, being full of electricity needs 4h (the solar panel working environment is: the average illumination value is: 48000LX), the trigger voltage of fan is 3.7v.Be full of under the electricity condition fan 20h that can work.Following table is measured when fine day when adopting such scheme; when lithium battery forces down in 3.07V; because the effect of protective circuit; battery no longer continues to provide energy to fan; fan stops operating; as shown in table 1 since the morning 10:30 to lithium cell charging, when lithium cell voltage reached 3.7V, fan began to rotate.
Table 1 (T=20~26 ℃)
(T=20~26 ℃) recorded when last table was fine day, can satisfy fan at least and rotate required electric weight in one day.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
