Abstract
The utility model relates to a charger for a mobile telephone, which comprises a housing, a charging circuit arranged in the housing, an input plug connected with an external power source and an output plug connected with a battery of the mobile phone, wherein, a spare battery is additionally arranged in the housing, a knob is arranged to be matched with the spare battery, and the spare battery can be controlled by the knob to be communicated by being respectively connected with the input plug and the output plug through a definite circuit in position. The spare battery can be a charged battery, and the charger for the mobile telephone can be connected with an external power supply to charge the battery of the mobile telephone and the spare battery. When no external power supply is provided, the mobile phone can be charged by the spare battery, and the structure of an integral machine is simple.
Description
The utility model relates to a kind of charger, and is particularly relevant with a kind of charger for mobile phone.
Along with expanding economy, the use and the popularity rate of mobile phone improve constantly, and when the running down of battery of mobile phone, can not normally dial, receive, need this moment it to be charged with charger for mobile phone, yet, make a general survey of existing charger for mobile phone, its structure is identical substantially, generally comprise input plug, output plug and charging circuit, during charging, input plug is connected with external power, and output plug is connected with battery of mobile phone, control by charging circuit, this charger for mobile phone the place that does not have external power as the vehicle that travels on, field work etc. can not be worked, and are difficult to guarantee rapidly, timely mobile phone is charged, make troubles to the user.
The purpose of this utility model is to provide a kind of charger for mobile phone, and it can not have to be cell-phone charging under the situation of external power rapidly, timely, and it is simple in structure, easy to use.
For reaching above-mentioned purpose, solution of the present utility model is:
A kind of charger for mobile phone, the output plug that comprises shell and be arranged on charging circuit wherein, the input plug that is connected with external power supply, be connected with battery of mobile phone, in above-mentioned shell, be provided with reserve battery in addition, and cooperate with reserve battery and to be provided with a may command reserve battery and in position to be connected the knob that is communicated with by certain circuit with input plug and output plug respectively.
In above-mentioned charger for mobile phone, this reserve battery can be rechargeable battery.
After adopting said structure, this charger both can be connected with external power, by charging circuit battery of mobile phone and reserve battery was charged, when no external power, can by reserve battery rapidly, timely mobile phone is charged bring convenience again, and complete machine structure is simple, convenient uses to the user.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a perspective exploded view of the present utility model;
Fig. 2 is an assembled state schematic diagram of the present utility model;
Fig. 3 is a user mode schematic diagram of the present utility model;
Fig. 4 is the circuit connection diagram of embodiment of the present utility model.
See also Fig. 1, Fig. 2, shown in Figure 3, an embodiment of charger for mobile phone of the present utility model is: be made up of shell 1, input plug 2, output plug 3, the charging circuit 4 and the standby rechargeable battery 5 that are arranged in the shell 1, also cooperate with standby rechargeable battery 5 and to be provided with a knob 6, the standby rechargeable battery 5 of these knob 6 may command in position is connected and is communicated with (because of some electric elements and interconnected relationship are prior art, not elaborating at this) respectively by certain circuit with input plug 2 and output plug 3.
Above-mentioned charger for mobile phone is when work, when external power, input plug 2 is communicated with external power, and output plug 3 is communicated with battery of mobile phone, at this moment, external power can charge by 4 pairs of batteries of mobile phone of charging circuit, simultaneously, because standby rechargeable battery 5 also is connected by circuit with input plug and is communicated with at this moment, therefore, external power is when charging to battery of mobile phone, also standby rechargeable battery 5 is charged, so, just often, all preserve suitable electric weight in the standby rechargeable battery 5, therefore under the situation of no external power, can stir knob 6, standby rechargeable battery 5 is communicated with output plug 3 by the standby charhing unit of certain electric elements composition, thereby battery of mobile phone is charged.
As shown in Figure 4 be the circuit part of the foregoing description, and this circuit connecting relation not only is confined to the disclosed a kind of connected mode of the utility model, also can adopt other mode to connect, having under the situation of external power as long as can reach, external power charges to mobile phone and reserve battery, under the situation of no external power, reserve battery can get final product the function that mobile phone charges.
The foregoing description only is a kind of execution mode of the present utility model, in use, the utility model also can adopt other similar structures, differing as reserve battery is decided to be rechargeable battery, also can be common dry cell, as long as it is by certain circuit element and be communicated with output plug 3, reach under the situation of no external power, can charge to battery of mobile phone gets final product, and just this charging can only be disposable, not as rechargeable battery can use repeatedly.
