The photovoltaic charged device of a kind of laptop computer portable
The utility model relates to a kind of notebook charging device, the photovoltaic charged device of especially a kind of laptop computer portable.
Along with developing rapidly of development of Mobile Internet technology; mobile interchange equipment act as key player in the middle of the live and work of people; improving constantly by science and technology; mobile device is towards more and more less, more and more thinner future development; mobile device is more and more less more and more thinner; the thing followed is that battery capacity but can not further improve; therefore often can run into the problems such as electricity is not enough when these mobile interchange equipment use in different operating environments, and each charging all needs a series of corollary equipment and power supply supply.And solar energy as a kind of whenever and wherever possible, inexhaustible regenerative resource, a kind of ideal solution can be provided.
The storage battery of the mobile device practicalities such as current notebook computer is the lithium battery of repeatedly discharge and recharge to be main, and this battery is except lightly, and capacitance is large, and has memory effect unlike ni-mh is the same with nickel-cadmium cell.The battery of general notebook computer is made up of shell, battery core (battery pack), operating circuit three part; Battery core generally by three string two and formula or other combination lithium battery group form, operating circuit comprise charging-discharging controller and protective circuit composition.Its shortcoming is as follows:
1, existing general family expenses notebook computer fills once electricity and can use 2-3 hour, and the time is shorter.
Need corresponding power supply adaptor and connecting line when 2, charging the battery, carry inconvenience and can not unify to use.
3, after battery electric quantity is used up, need to find power supply to fill a little.
4, battery capacity can decline to some extent along with the increase of service time, and therefore correspondingly computer use time also can shorten.
5, battery capacity can not meet outdoor non-transformer local conditions.
Utility model content
The utility model provides the photovoltaic charged device of simple, the safe and reliable laptop computer portable of a kind of structure.
Realize the photovoltaic charged device of laptop computer portable of the utility model object, comprise the secondary battery unit and flexible expandable formula solar charging electric unit that are connected by USB interface;
Described secondary battery unit comprises shell, is positioned at battery core and the operating circuit of shell, is positioned at USB and the electricity display screen of case surface;
Described flexible expandable formula solar charging electric unit comprises retractable and flexible solar cell and is connected with retractable and flexible solar cell, and is received battery container wherein, and described retractable and flexible solar cell is provided with USB interface.
The beneficial effect of the photovoltaic charged device of laptop computer portable of the present utility model is as follows:
The photovoltaic charged device of laptop computer portable of the present utility model, structure is simple, and volume is little, is convenient for carrying, and is convenient to outdoor office and amusement use; Adopt lithium battery group as storage battery; capacity is large, can repeatedly discharge and recharge; solar cell adopts retractable and flexible thin-film solar cells; hull cell can be pulled out from receiver during use; battery plug is inserted the socket that storage battery is corresponding; the irradiation that solar cell receives sunlight can be charged to storage battery; can regulate the size that solar cell launches as required; can hull cell be taken in receiver after finishing using; both can protective film battery, be also easy to carry.In addition storage battery is also equipped with battery capacity indication lamp and USB, can charges to other mobile devices.
Accompanying drawing explanation
Fig. 1 is the structural representation of the photovoltaic charged device of laptop computer portable of the present utility model.
As shown in Figure 1, the photovoltaic charged device of laptop computer portable of the present utility model, comprises the secondary battery unit 1 and flexible expandable formula solar charging electric unit 2 that are connected by USB interface;
Described secondary battery unit 1 comprises shell, is positioned at battery core and the operating circuit of shell, is positioned at USB 11 and the electricity display screen 12 of case surface;
Described flexible expandable formula solar charging electric unit 2 comprises retractable and flexible solar cell 22 and is connected with retractable and flexible solar cell 22, and the battery container 23 received wherein, described retractable and flexible solar cell 22 is provided with USB interface 21.
Secondary battery unit adopt three strings two and formula or other compound modes lithium battery group as battery core; operating circuit control overcharges and overdischarge the discharge and recharge of battery core and protection battery core; USB charging socket is provided to outside, and by display screen display battery core electricity.
1) battery core adopts lithium battery group, can carry out the connection in series-parallel compound mode of varying number according to specific requirement.
2) operating circuit can carry out statistics and the control of discharge and recharge number of times to battery, and protection battery pack, provides outside USB charging socket in addition, for other mobile devices, can show battery electric quantity by display screen, prevent overcharge and overdischarge.
3) outside USB can to the mobile power supply equipment such as MP3, mobile phone.
4) display screen can show current electric quantity, and reminding user charging and stopping electric discharge, enter resting state when not using.
Charhing unit adopts retractable and flexible thin-film solar cells, it can be pulled out from receiver, charged, freely switch according to demand in different size by custom size to different storage batterys during use; Be involved in when not using in receiver, be convenient for carrying while protection battery.
The advantage of the photovoltaic charged device of laptop computer portable of the present utility model is as follows:
1) structure simple and safe, flexible for installation, be convenient for carrying and member replacing;
2) solar energy resources is taken full advantage of, energy-conserving and environment-protective;
3) little, the lightweight feature of volume of flexible thin-film solar is taken full advantage of;
4) outdoor office environment for use can be met, as long as there is sunlight just can working entertainment whenever and wherever possible;
5) can use as mobile charger separately, except the energy needed for notebook computer is provided, also can power to other mobile devices;
6) according to demand can self-defined battery size, meet distinct device requirement.
Embodiment recited above is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the utility model designs spiritual prerequisite; the various distortion that the common engineers and technicians in this area make technical solutions of the utility model and improvement, all should fall in protection range that claims of the present utility model determine.
