Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of compact conformation, power supply adaptor with multiple input modes, and can carry out charging (comprising battery) for multiple electronic product, this power supply adaptor is provided with the possibility that safety switch gets an electric shock to facilitate control inputs source and minimizing user in addition.
The utility model solves the problems of the technologies described above adopted technical scheme:
A kind of portable power supply adapters, its structure comprises main body, rectifier transformer device is provided with in described main body, rectifier transformer device electrical connection DC output end, battery chamber and charging circuit is also provided with in described main body, described battery chamber's electrical connection DC output end, is provided with booster circuit between battery chamber and DC output end; Described charging circuit is arranged on rectifier transformer device and is electrically connected battery chamber with between DC output end, is provided with unidirectional transport element between charging circuit and battery chamber.Make adapter can be reached the possibility of multi input by cell powers by arranging battery chamber, by arranging the number of batteries needed for booster circuit reduction.Charging circuit and arranging of unidirectional transport element coordinate rechargeable battery to reach long-term object of continuing a journey.
As preferably, between described battery chamber and DC output end, be provided with switching circuit.The interpolation of switching circuit adds control performance and fail safe.
Further, described switching circuit comprises hand switch, and hand switch is arranged between battery chamber and DC output end.The setting of hand switch makes user can control to select commercial power charged or battery charging, it also avoid battery and exports simultaneously and input the situation causing decline useful life.
Further, described switching circuit comprises automatic switch, and automatic switch controls opening and closing according to the connection of DC output end and external equipment.In formation loop, charging end, the possibility that user gets an electric shock could be decreased, is specially adapted to the charging device that charging end is exposed, as lithium battery when the setting of automatic switch makes DC output end be connected with external equipment.
Further, described DC output end comprises USB charging end and lithium cell charging end.Multi output end can meet the output demand of different electronic product.
Further, described lithium cell charging end is arranged on above battery chamber, and described battery chamber offers battery cover in the main body on limit, lithium cell charging side.Lithium cell charging end and battery chamber's homonymy design the output demand completing electronic product in the situation not expanding power supply adaptor volume, and the design of battery cover makes battery can pass in and out power supply adaptor easily.
The utility model compared with the existing technology has the following advantages and effect: by the setting of battery chamber, charging circuit and DC output end, make power supply adaptor can reach the function of multi input mode multi input end; Improve control and fail safe by arranging hand control and automation switch simultaneously; Rational vibrational power flow ensure that the volume of portable power supply adapters is beneficial to and carries convenient operation.
