Abstract

The utility model relates to a multifunctional charger which consists of a charger shell(5), a charge circuit(3) positioned in the shell(5); wherein the shell(5) is provide with a hand shaking generator(4) and a spare pile(1); a solar pile(2) is externally connected with the shell though the connecting item; the hand shaking generator(4), the spare pile(1) and the solar pile(2) are respectively connected with the corresponding connector of the charge circuit; the charge circuit is also provided with a cable connector to connect with the commercial electricity and a cable connector to connect with the car power. The utility model can charge the equipment by the two hundred and twenty voltage commercial electricity in normal time and can charge the equipment by the car power when customers drive out; if the customer goes out in a fine day the utility model can charge the equipment by the self-solar energy battery without commercial electricity or car; if the conditions are all not provided, the utility model can charge the equipment by the hand shaking generator.

Description

The multipurpose charger

(1) technical field

The utility model relates to a kind of charger, relates to a kind of multipurpose charger that utilizes mains supply, automobile power source, solar energy, hand generator to charge for chargeable electrical equipment such as mobile phone, PDA, travelling electrical equipment specifically.

(2) background technology

Along with the develop rapidly and the growth in the living standard of people's door of science and technology, the use of travelling such as mobile phone and palmtop PC, walkman, electric shaver electrical equipment is also more and more universal.But in travelling, especially in the open air, the time regular meeting problem because of can't in time charging and cause electrical equipment to use for electrical equipment takes place.Particularly when unexpected stormses such as generation floods, earthquake, power issue is just outstanding to show important.

(3) summary of the invention

The purpose of this utility model provides a kind of multipurpose charger that utilizes mains supply, automobile power source, solar energy, hand generator to charge for chargeable electrical equipment such as mobile phone, PDA, travelling electrical equipment just at the problems referred to above.

The purpose of this utility model can realize by following measure:

Multipurpose charger of the present utility model comprises the charger case body, and is arranged on the charging circuit in the housing, wherein, is provided with hand-rail type generator and battery backup in described housing, by connector solar battery group is installed outside housing; Described hand-rail type generator, battery backup and solar battery group insert the corresponding interface of charging circuit respectively; On charging circuit, also be provided with the cable interface and the cable interface that is connected automobile power source that connect civil power.

Charger of the present utility model can utilize civil power 220V that electrical equipment is charged at ordinary times, can utilize automobile power source that electrical equipment is charged when driving out; When no civil power, no automobile,, then can use the rechargeable solar battery that carries if fine day is gone out; If under the situation that above-mentioned condition does not all possess, also can utilize the hand generator that self is equipped with that electrical equipment is charged.Self carry a reserve battery owing to charger of the present utility model in addition, and be provided with multiple output socket and bulb, this just provides convenience for the emergency lighting in field.
