Background technique

Nowadays, mobile phones have become an indispensable communication device for people's daily life and work. With the development of technology, the screens of mobile phones are getting larger and larger, and the power consumption of mobile phones is also becoming more and more serious. The only battery power in mobile phones cannot meet the needs of mobile phones. The need for long-term use, but it is extremely inconvenient to find a charging power source when the user goes out and the mobile phone is out of power. the

Currently commonly used emergency charging equipment for mobile phones are: mobile phone back clip battery, mobile power supply

Its disadvantages are:

1. Mobile phone back clip battery: It takes a long time to install a polymer lithium battery on the back of the mobile phone. On the one hand, it increases the thickness and weight of the mobile phone. the

2. Mobile power supply: On the one hand, the mobile phone is usually a must-carry device for users, but the mobile power supply may not be carried with you. On the other hand, like the back clip battery, once it runs out of power, it will not be able to play the role of emergency charging. the

Contents of the invention

The purpose of this utility model is to solve:

1. The problem of inconvenient emergency charging of mobile phones when people go out. the

2. The problem that extra charging equipment needs to be carried with you. the

In order to achieve the above-mentioned purpose, the utility model adopts a dry battery which is relatively easy to find as a power source, and puts a transformer circuit inside the main body of the mobile phone case as an emergency charging device for the mobile phone at any time. The dry battery is fixed by using the card position and magnet adsorption of the main body of the mobile phone case to ensure the convenience of loading and unloading of the dry battery, prevent falling, reduce the thickness of the main body of the mobile phone case, make it easy to carry, and ensure the morphological integrity of the main body of the mobile phone case. the

In the technical scheme of the utility model, it also has the following technical features: the main body of the mobile phone case adapted to the shape of the mobile phone, the main body of the mobile phone case is provided with a battery compartment, the battery compartment is used to place dry batteries, and the two sides of the battery compartment are provided with connecting dry batteries The metal contacts, the battery compartment is provided with a cover. the

In the technical scheme of the present invention, it also has the following technical features: the main body of the mobile phone case is provided with a voltage transformer circuit, when 1-3 dry batteries are placed, the voltage is boosted by the voltage transformer circuit and the mobile phone is charged; when more than 3 dry batteries are placed When a large number of dry batteries are used, the voltage is lowered by the transformer circuit and the mobile phone is charged. the

In the technical solution of the present invention, it also has the following technical features: the voltage transforming circuit in the main body of the mobile phone shell is provided with a plug suitable for the mobile phone. the

In the technical solution of the utility model, it also has the following technical features: the transformer circuit is connected to the battery compartment with a power cord connected to the dry battery. the

In the technical solution of the utility model, it also has the following technical features: the length of the slot where the dry battery is installed in the battery compartment is equal to the length of a dry battery. the

Under the premise of limited volume space, the utility model enables the mobile phone case not only to have a protection function, but also to have an emergency charging function. the
