Description
Technical field
The utility model relates to a kind of portable power source.
Background technology
Existing portable power source, is the portable charger integrating power supply and charge function, can charges whenever and wherever possible or standby power to digital equipments such as mobile phones.Generally by lithium cell (or dry cell, more rare) as charge storage unit, convenient to use.But its electricity stored is always limited, and could use after also needing charging, the place provided not having power supply can not well be used.
Utility model content
The purpose of this utility model is: provide a kind of portable power source, whenever and wherever possible to portable power source charging, can improve the applicability of portable power source.
To achieve these goals, the technical solution of the utility model is:
A kind of portable power source, comprises shell, liquid crystal display screen, LED illumination lamp, charging inlet, power output interface, control module and power switch button; Described control module comprises the recognition unit for identifying the charging input source that described charging inlet accesses; Described charging input source is produced by hand charging module, solar recharging module or power supply adaptor charging module.
Further, described hand charging module comprises charge cable, hand generator and crank handle.
Further, described recognition unit comprises position transducer, the position that the motor shaft of described hand generator rotates by described position transducer or angular transition are the signal of telecommunication, and are sent to described control module, transformed and be presented on described liquid crystal display screen by described control module.
Further, the periodic pulse signal of described recognition unit detection and Identification hand generator judges the charging input source that described charging inlet accesses.
Hand charging inputs by the utility model, solar recharging input or power supply adaptor charging input are integrated in same input interface, at the charging input source that control circuit intralamellar part Intelligent Recognition is different, in simplifying the structure of portable power source, effectively prevent the risk of user's wrong plug charging inlet; The output voltage of hand generator is presented on liquid crystal display screen by the utility model design in real time, and user can control hand rotating speed in the most rational scope according to the pointer of liquid crystal display screen panel board.

Fig. 3 is the structural representation right view of the utility model portable power source.
Fig. 4 is the structural representation that the utility model portable power source is connected with hand charging module.
Fig. 5 is the circuit diagram detecting hand generator voltage input feature vector.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 to Fig. 3, a kind of portable power source, comprise shell 1, liquid crystal display screen 2, LED illumination lamp 3, charging inlet 4, power output interface 5, control module and power switch button 7; Described control module comprises the recognition unit for identifying the charging input source that described charging inlet 4 accesses; Described charging input source is produced by hand charging module, solar recharging module or power supply adaptor charging module.
Preferably, please mainly shown in Figure 4, described hand charging module comprises charge cable 8, hand generator 9 and crank handle 10; Described solar recharging module is also connected with charging inlet 4 by the charge cable identical with charge cable 8 with power supply adaptor charging module.
Because of under hand charged state, portable power source needs to open liquid crystal display screen 2 and shows rotational speed meters dial plate, and under other charging modes, portable power source can cut out liquid crystal display screen and save electric energy, therefore the intelligent identification technology of different charging input source is mainly to the Intelligent Recognition of hand charging input mode.
Preferably, described recognition unit comprises position transducer, the position that the motor shaft of described hand generator 9 rotates by described position transducer or angular transition are the signal of telecommunication, and are sent to described control module, transformed and be presented on described liquid crystal display screen 2 by described control module.The signal of telecommunication is analog voltage signal, digital pulse signal, or digital communication agreement etc.Position transducer mainly includes but not limited to relatively, absolute type encoder, sine and cosine encoder, resolver, grating, magnetic grid, Hall element, proximity switch etc.
In addition, portable power source can also identify hand charged state by the voltage output characteristics of hand generator itself.To DC generator, portable power source the commutator pulse signal of detection and Identification DC generator can identify hand charged state.To alternating current generator, portable power source can detection and Identification alternating current generator export sinusoidal wave peak value identify hand charged state.
Preferably, the periodic pulse signal of described recognition unit detection and Identification hand generator 9 judges the charging input source that described charging inlet 4 accesses.
Shown in Figure 5, be the embodiment detecting hand generator voltage input feature vector.The voltage inputted through charging inlet 4 can obtain unipolar positive voltage after rectifier bridge.To DC generator, this positive voltage comprises the crest voltage of commutator pulse; To alternating current generator, this positive voltage comprises the sinusoidal wave crest voltage after rectification.
Use inductance L 1 and electric capacity C1 to form filter, can hold at electric capacity C1 the mean value obtaining input voltage.This mean value be less than filtering before the peak value of input voltage.Power taking resistance R1/R2 is a bit larger tham resistance R3/R4, then can obtain periodic pulse signal at the output of comparator U1, each pulse correspond to the peak value of pulse of input voltage or sinusoidal wave peak value.Control circuit is hand charging module by what identify that these periodic pulse signals can identify that charging inlet 4 accesses, also can identify the charged state of hand generator simultaneously.
In sum, the utility model whenever and wherever possible to portable power source charging, can improve the applicability of portable power source.
