Description
Technical field
The utility model relates to a kind of portable power source, is specifically related to a kind of portable power source with the flashlight function.
Background technology
A kind of portable charger that integrates power supply and charge function of portable power source; Can be for multiple digital products such as mobile phone, MP3, MP4, mobile phone, PDA, palmtop PC, handheld device charge or standby power supply whenever and wherever possible, generally all be that outdoor activities such as travel outdoors, go on business are used, and in these outdoor activities, many times also need illuminations; But present Portable DC portable power source generally all only possesses the function of power storage; There is not the difunctional synthetic function of flashlight and portable power source, so when needing illumination, need be equipped with flashlight separately; Not only increase use cost, and increased the burden of carrying.
The utility model content
To the deficiency of prior art, the utility model provides a kind of portable power source that the flashlight function is arranged that possesses, and has saved use cost, carries also very convenient simultaneously.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The portable power source of band flashlight function; It comprises a processor; Said processor has a positive output end and a negative output terminal; The positive and negative electrode that said positive output end and negative output terminal are connected to rechargeable battery respectively is the rechargeable battery charging, and the portable power source of said band flashlight function further comprises a flashlight circuit, and this flashlight circuit and processor electrically connect.
As improvement; Said flashlight circuit comprises a LED lamp, switch key and a switch triode; The positive pole of said LED lamp is connected to positive output end, and its negative pole is connected to the collector electrode of switch triode, and the base stage of said switch triode is connected to the I/O end of processor; One end of the emitter of switch triode and switch key all is connected to negative output terminal, and the other end of switch key is connected to the KEY end of processor.
Preferably, said flashlight circuit further comprises the current-limiting resistance R1 that connects with the LED lamp.
Preferably, said flashlight circuit comprises that further one is connected in the current-limiting resistance R2 between the base stage of I/O end and switch triode of processor.
The portable power source of the band flashlight function that the utility model is set forth, compared with prior art, its beneficial effect is: the utility model is implanted the flashlight circuit in original portable power source; Make portable power source have the function of flashlight simultaneously; When needing illumination, need not to be equipped with separately illuminations, improved the functional integration of product; Compare two kinds of Different products of stand-alone development and can reduce resource and cost, carry also very convenient simultaneously.
Description of drawings
Accompanying drawing 1 is the circuit theory diagrams of the portable power source of the utility model band flashlight function.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the portable power source of the band flashlight function of the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
Because the circuit theory of conventional portable power source is a common practise; Therefore in the utility model embodiment, only illustrate the related structure division of flashlight function, as shown in Figure 1, the portable power source of band flashlight function; It comprises processor (MCU) U1; This processor U1 has a positive output end and a negative output terminal, and the positive and negative electrode (wherein just very B+, negative pole is B-) that positive output end and negative output terminal are connected to rechargeable battery respectively is the rechargeable battery charging.For realizing having the flashlight function simultaneously, in original portable power source circuit, implant flashlight circuit 1, flashlight circuit 1 electrically connects with processor U1.
Particularly; In the utility model preferred embodiment; Flashlight circuit 1 comprises a LED lamp D1, switch key K and a switch triode Q1, and the positive pole of LED lamp D1 is connected to positive output end (perhaps B+ end), and its negative pole is connected to the collector electrode of switch triode Q1; The base stage of switch triode Q1 is connected to the I/O end of processor U1; The end of the emitter of switch triode Q1 and switch key K all is connected to negative output terminal (or B-end), negative output terminal ground connection wherein, and the other end of switch key K is connected to the KEY end of processor U1.In addition, the current-limiting resistance R1 that also connects on the LED lamp D1, the current-limiting resistance R2 between the I/O end of processor U1 and the base stage of switch triode Q1.
Its operation principle is: the positive pole of LED lamp D1 is connected to the positive pole of rechargeable battery through current-limiting resistance R1; Positive output end by processor U1 is that LED lamp D1 provides 3-4.2V voltage, and when pressing switch key K, the direct voltage that the KEY of processor U1 is held drags down; After processor U1 detects this LVD; Control I/O end output height/low level, thereby the on/off of control switch triode Q1, and then realize whether luminous control to LED lamp D1.The utility model only needs in original portable power source, to implant the flashlight circuit can realize that the energy replenishes and the dual-use function of flashlight lighting; It is simple in structure; And be that portable power source self charges when perhaps portable power source is for other digital products chargings; Do not influence the use of flashlight, very easy to use.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection range of the utility model claim all according to the technical scheme and the design of above description.
Claims (4)
