Abstract
The utility model relates to the technical field of chargers, and especially refers to an AC and DC combined charger comprising a housing, a charging module arranged in the housing, charging cells and a boost module, wherein an input terminal of the charging module is electrically connected with a plug on the housing, an output terminal of the charging module is connected in parallel with the charging cells and a charging interface, an output terminal of the charging cells is connected with an input terminal of the boost module, an output terminal of the boost module is connected with the charging interface, a charge switch is arranged between the charging module and the charging cells, and a discharge switch is arranged between the charging cells and the boost module. The AC and DC combined charger is easy in operation, combines of a commercial power charging function with that of a portable power source, so double functions of a normal charger and the portable power source are both provided; and the AC and DC combined charger is small in size, beautiful and environmental friendly, saves material and energy source, prevents secondary pollution of the portable power source, simultaneously reduces burden of consumers, and is convenient to be carried outside by people.
Description
Technical field
The utility model relates to the technical field of charger, especially a kind of AC and DC one charger.
Background technology
The charger of Shi Yonging in the market, all be directly power device to be charged, if do not having under the situation of civil power, can adopt charging precious (refer to directly to give charging of mobile devices and self to have charge storage unit device) that power device is charged, but these two kinds of charging modes are independent device separately, are not easy to people and go out to carry.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of AC and DC one charger is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of friendship, direct current one charger, be used for the charging of outside power device, comprise housing, be arranged on the charging module of enclosure interior, rechargeable battery and supercharging module, the input of charging module is electrically connected with plug on the housing, output charged in parallel battery and the charging inlet of described charging module, the output of rechargeable battery is connected with the input of supercharging module, the output of supercharging module links to each other with charging inlet, between charging module and rechargeable battery, be provided with the charge switch of rechargeable battery, be provided with the discharge switch of rechargeable battery between rechargeable battery and the supercharging module.
Have the entrance of putting into rechargeable battery on the described housing, loam cake is installed on the entrance.
Described rechargeable battery is lithium battery.
The utility model is easy to operate, alternating current charging and charged with direct current are combined, had the common charger dual-use function precious with charging concurrently, appearance looks elegant, volume are small and exquisite, material and the energy had both been saved, prevented the precious secondary pollution of charging again, alleviated consumer's burden simultaneously, being convenient to people again goes out to carry, having reduced will be with the embarrassment of a plurality of charging devices when going out, increased the charging ability of charger greatly, changed the history that common charger does not have civil power not charge, filled up common charger and can not continue the blank of filling.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is fundamental diagram of the present utility model.
Fig. 2 is structural representation of the present utility model.
Among the figure: 1. housing, 2. rechargeable battery, 3. plug, 4. charging inlet.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Friendship as shown in Figure 1, direct current one charger, be used for the charging of outside power device, it is characterized in that: comprise housing, be arranged on the charging module of enclosure interior, rechargeable battery and supercharging module, the input of charging module is electrically connected with plug on the housing, output charged in parallel battery and the charging inlet of described charging module, the output of rechargeable battery is connected with the input of supercharging module, the output of supercharging module links to each other with charging inlet, between charging module and rechargeable battery, be provided with the charge switch of rechargeable battery, be provided with between rechargeable battery and the supercharging module and make rechargeable battery after charge switch disconnects, the discharge switch of the rechargeable battery that supercharging module and power device circuit are connected.
Have the entrance of putting into rechargeable battery 2 on the housing 1, loam cake is installed on the entrance, rechargeable battery 2 is lithium battery.
Charging module receives civil power and charges to rechargeable battery or power device, 220V changes 5V into voltage, when rechargeable battery charges to power device, is 2.4V-3.7V, so just need the supercharging module that voltage is promoted to 5V, just can reach the required voltage of power device.
As shown in Figure 2, there are three kinds of charging modes in the utility model:
(1), when civil power charges to power device separately, the charge switch of rechargeable battery disconnects, the discharge switch of rechargeable battery disconnects, charging module directly with being transferred to power device after the civil power transformation, charges;
(2), when civil power is given power device and rechargeable battery charging simultaneously, the charge switch of rechargeable battery is communicated with, the discharge switch of rechargeable battery disconnects, charging module directly is transferred to power device and rechargeable battery after with the civil power transformation, charges;
(3), when rechargeable battery charges to power device, civil power disconnects, the charge switch of rechargeable battery disconnects, the discharge switch of rechargeable battery is communicated with, the electric weight of laying in the rechargeable battery directly is transferred to power device after by the supercharging of supercharging module, charges.
Above-mentioned execution mode only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection range of the present utility model.
Claims (3)
1. friendship, direct current one charger, be used for the charging of outside power device, it is characterized in that: comprise housing, be arranged on the charging module of enclosure interior, rechargeable battery and supercharging module, the input of charging module is electrically connected with plug on the housing, output charged in parallel battery and the charging inlet of described charging module, the output of rechargeable battery is connected with the input of supercharging module, the output of supercharging module links to each other with charging inlet, between charging module and rechargeable battery, be provided with the charge switch of rechargeable battery, be provided with the discharge switch of rechargeable battery between rechargeable battery and the supercharging module.
