Secondly, the cradle of the charging device of the mobile phone of prior art, specification (voltage, pin position) are all inconsistent, all need to be equipped with and the corresponding to charging device of this cradle, have also increased user's cost for this reason.
Therefore, inventor of the present utility model is through concentrating on studies, design a kind of be fit to dissimilar (for example, Motorola, Nokia ... Deng) the charging device of mobile phone.Mobile phone charging device of the present utility model makes when mobile phone does not have electricity, just can promptly use temporarily.
A purpose of the present utility model provides a kind of charging device that is fit to dissimilar mobile phones, this device adopts general dry cell (No. 3 or No. 4), and cooperate the circuit conversion design, make this device be fit to dissimilar mobile phone machine uses, thereby increase the convenience of this product.
Another purpose of the present utility model is the double mobile phone charging device that a kind of caller identification or vibrating alert function are provided.
The utility model is to realize its purpose in the following manner, that is, a kind of charging device that is fit to dissimilar mobile phones comprises a battery case that is used to place dry cell; A supply convertor box mechanically links to each other with above-mentioned battery case with electric going up, and being used for conversion battery case dry cell voltage is the required voltage of mobile phone; Above-mentioned supply convertor box is provided with voltage change-over switch, by operate this switch can the conversion charger charging voltage of output; A connecting line is used to connect the charging voltage output socket that mobile phone power supply voltage is imported socket and charger.
The utility model comprises a caller identification circuit in addition, by being connected to the antenna receiving signal of this circuit, realization sound, light or vibrating alert.
In order to be more readily understood the utility model, describe embodiment of the present utility model in detail below with reference to each accompanying drawing.But this embodiment only is used for the utility model is described purpose, and is not restrictive to the utility model.In this each accompanying drawing:
Fig. 1 is the structural general synoptic diagram of the utility model;
Fig. 2 is a structural decomposing schematic representation of the present utility model;
Fig. 3 is another connected mode schematic diagram of mobile phone of the present utility model and charger;
Fig. 4 is other more a kind of connected mode schematic diagram of mobile phone of the present utility model and charger;
Fig. 5 is the utility model principle electrical circuit figure;
Fig. 6 is the schematic diagram of the vehicle charging mode of utilizing the automobile cigarette lighter power supply of prior art;
Fig. 7 is the schematic diagram of the travelling charging modes that utilizes the location power supply of prior art;
Fig. 8 is the schematic diagram that the seat of power supply fills charging modes in the utilization man of prior art.
Describe embodiment of the present utility model in detail below with reference to Figure of description.Specifically see figures.1.and.2, wherein represent structural general synoptic diagram of the utility model and decomposing schematic representation respectively.With reference to Fig. 1, label 1 is represented mobile phone handsets.Label 2 representative charger of the present utility model, mobile phone handsets and charger of the present utility model are connected on electric by being plugged on.Battery can be put into or take out to battery cover on the label 23 representatives charger of the present utility model by opening this battery cover.Label 26 representative voltage change over switches are by operating the charging voltage that this switch can the convert charging device, to be fit to dissimilar mobile phones.The general picture of charger for mobile phone of the present utility model as can be seen from Figure 1.Refer again to Fig. 2 of expression the utility model charger for mobile phone decomposing schematic representation below, label 1 is represented mobile phone handsets.Label 2 representatives charger of the present utility model.Label 3 is represented connecting line.Label 11 is represented the supply socket on the mobile radio station telephone bandset.Label 21 is represented the battery case of the utility model charger.Label 22 is represented dry cell.Label 23 is represented battery cover.Label 24 supply convertor boxes.Label 25 is represented the power supply output plughole on the supply convertor box.Label 26 representative voltage change over switches are by operating the charging voltage that this switch can the convert charging device, to be fit to the different power voltage of dissimilar mobile phones.Label 31 representative is connected to the direct current joint on the connecting line 3 of power output end of charger.Label 32 is represented the direct current input crossover sub that is connected to the mobile phone handsets end of connecting line 3, can be converted to the mobile phone handsets that are fit to various power supply input pins by this crossover sub.In addition, in order to adapt to the different voltage requests of multiple mobile phone, supply convertor box 24 also can carry out conversion.
