Description

Mobile charger

technical field

The utility model relates to a charger, in particular to a mobile charger.

Background technique

With the development of social economy, smart phones have been widely used. Although smart phones are powerful, easy to use and beautiful in appearance, their battery life has always been the bottleneck of this type of electronic products due to their large screens and high power consumption. Therefore, it is necessary to design a portable charging device as an effective auxiliary for such electronic products. Existing mobile phone chargers can only charge the battery of the mobile phone under the condition of having a power supply. When people go out, as the battery of the mobile phone is exhausted, and there is no power supply nearby, the mobile phone cannot be used, which brings a lot of inconvenience to people. The sudden power failure of mobile phones during business activities will cause huge losses. Moreover, general chargers charge external devices with a fixed current output, and some external devices that require a charging current will have temperature during charging, which poses a serious safety hazard.

Contents of the invention

Therefore, in view of the above problems, the utility model proposes a mobile charger that is safe and reliable, can be charged anytime and anywhere without a power supply, and is convenient to carry.

In order to solve this technical problem, the utility model adopts the following solutions: a mobile charger, including a plug, a charger body and an output plug, and the charger body includes a battery, an intelligent charge and discharge control system and a current limiting protection circuit. The plug is connected to the input terminal of the intelligent charging and discharging control system, the charging port of the intelligent charging and discharging control system is connected to the storage battery, and the discharging port of the intelligent charging and discharging control system is connected to the output plug through a current limiting protection circuit.

Further, it also includes a power display circuit and an indicator light, the intelligent charge and discharge control system is connected to the input end of the power display circuit, and the output end of the power display circuit is connected to the indicator light.

By adopting the above-mentioned technical scheme, the beneficial effect of the utility model is: when the mobile phone suddenly loses power and there is no power supply to charge the mobile phone, the utility model can directly charge the mobile phone anytime and anywhere, making it more convenient for people to use the mobile phone; The new type is small in size, simple in structure, easy to carry, and low in cost; and it is equipped with a current limiting protection circuit, which can automatically adjust the charging current and charging voltage, and charge the external device with the best charging current and charging voltage, eliminating the need for fixed charging. Current output is a potential safety hazard for charging external devices.

Detailed ways

The utility model is further described now in conjunction with accompanying drawing and specific embodiment.

Referring to Fig. 1 and Fig. 2, a preferred mobile charger of the present invention includes a plug 1, a charger body 2, an output plug 3, a power display circuit 4 and an indicator light 5, and the charger body 1 includes a storage battery 21. Intelligent charge and discharge control system 22 and current limiting protection circuit 23, the plug 1 is connected to the input end of the intelligent charge and discharge control system 22, the charging port of the intelligent charge and discharge control system 22 is connected to the battery 21, and the intelligent charge and discharge control system 22 is connected to the battery 21. The discharge port of the charging and discharging control system 22 is connected to the output plug 3 through the current limiting protection circuit 23, and the intelligent charging and discharging control system 22 is connected to the input terminal of the electric quantity display circuit 4, and the output terminal of the electric quantity display circuit 4 is connected to the indicator Lamp 5 is connected.

When the utility model is in use, an external power supply is used to charge the storage battery 21 of the machine through the plug 1, and the power of the machine is displayed by the indicator light 5 connected with the power display circuit 4, and the indicator light 5 is always on to prompt the machine The power has been stored, and the other indicator lights 5 will flash to indicate that the capacity of the machine is being charged. After the charge is saturated, the machine will enter the standby low power consumption state in an intelligent way. The protection circuit 23 can automatically adjust the charging current and charging voltage, and charge the external equipment with the best charging current and charging voltage. After each group of external equipment is fully charged, it will automatically turn off the output of the machine to the external equipment in an intelligent manner.

With the utility model, when the mobile phone is suddenly cut off and there is no power supply to charge the mobile phone, the utility model can directly charge the mobile phone anytime and anywhere, making it more convenient for people to use the mobile phone; the utility model is small in size, simple in structure, and easy to carry. The cost is low; and there is a current limiting protection circuit on it, which can automatically adjust the charging current and charging voltage, and charge the external device with the best charging current and voltage, eliminating the safety hazard of charging the external device with a fixed current output.

Although the utility model has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that, without departing from the spirit and scope of the utility model defined by the appended claims, changes in form and details may be made. Making various changes to the utility model is within the protection scope of the utility model.
