Due to the integrated structure of the built-in battery and the shell, the existing charging mobile phone case has a large volume and heavy weight, and is not portable enough, and the built-in battery cannot be separated from the shell for replacement, so that the stored power is limited, and therefore, Once the built-in battery is damaged, the entire charging case will lose its function.

Contents of the invention

The technical problem to be solved by the utility model is to provide a portable charging mobile phone case with small volume, light weight and replaceable or removable power supply for the deficiencies of the prior art.

The technical problem to be solved by the utility model is realized through the following technical solutions. The utility model is a portable charging mobile phone shell, which includes a shell that wraps the mobile phone. There is a charging chip electrically connected to the charging connector; there is an opening in the middle of the housing, and the opening is covered with an elastic film layer, and the elastic film layer is stretched to the back of the housing to form a power storage compartment The layer is provided with an electrical contact near the edge of the hole, and the electrical contact is electrically connected to the above-mentioned charging chip.

The technical problems to be solved by the utility model can be further realized through the following technical solutions. In the above-mentioned portable charging mobile phone case: the electrical contact is arranged at a position capable of contacting the two poles of the placed power supply.

The technical problems to be solved by the utility model can be further realized through the following technical solutions. In the aforementioned portable charging mobile phone case: the power supply is a battery pack.

The technical problems to be solved by the utility model can be further realized through the following technical solutions. In the above-mentioned portable charging mobile phone case: an elastic cortex is adhered to the back of the case.

The technical problems to be solved by the utility model can be further realized through the following technical solutions. In the above-mentioned portable charging mobile phone shell: the shell is provided with a camera through hole, an earphone through hole and a speaker through hole.

Compared with the prior art, the utility model opens a hole in the middle of the housing and arranges an elastic film layer, so that the elastic film layer can be used as a power storage compartment to place the power supply after stretching to the back of the housing; by setting the elastic film layer on the Electrical contacts, and electrically connect the electrical contacts with the charging chip to realize power transmission and transformation; by setting the charging connector, the electric energy converted by the charging chip is charged into the mobile phone. The utility model changes the traditional method of connecting an external power supply through a USB line to charge the charging mobile phone case, and solves the problem of being unable to charge in time because the USB line cannot be found, and the power supply and the mobile phone case can be separated, It solves the problem of large volume and weight in the daily use of the mobile phone case, and the form and capacity of the power supply used can also be changed according to needs, which is very flexible and convenient.

detailed description

The specific technical solutions of the utility model are further described below, so that those skilled in the art can further understand the utility model, without limiting the rights thereof.

Referring to Figures 1-5, a portable charging mobile phone case includes a housing 1 that wraps the mobile phone. The bottom of the housing 1 is provided with a charging connector 2 inserted in the charging port of the mobile phone. The position of the charging connector 2 is packaged with a charging chip 3 electrically connected to the charging connector 2. The charging chip 3 can convert the incoming power supply voltage/current into the charging voltage/current required by the mobile phone; The opening 4 is covered with an elastic film layer 5, and the elastic film layer 5 is stretched toward the back of the housing 1 to form a power storage compartment 6, which is convenient for putting in a power supply to charge the mobile phone. When charging is not required, the power supply It can be taken out, and after the power supply is taken out, the elastic film layer 5 is restored to its original state without affecting the volume and weight of the utility model. An electric contact 7 is arranged at the edge of the elastic film layer 5 near the opening 4, and the electric contact 7 is connected to the The charging chip 3 is electrically connected to realize the transmission of electric energy;

The electrical contact 7 is arranged at a position capable of contacting the two poles of the placed power supply;

The power supply is a battery pack, and different battery packs are powered in series or in parallel according to the needs of use, for example: use four 1.5V dry batteries in series as the power supply or use four 3.8V dry batteries in parallel as the power supply;

Since the power supply is detachable from the shell 1, it is convenient to replace battery packs of different capacities to power the mobile phone, replacing the traditional way of using a USB cable to introduce an external power supply for power supply, and solving the problem that the mobile phone cannot be charged in time because the USB cable cannot be found ;

The back of the housing 1 is covered with an elastic skin layer 8, which plays a role of protection and appearance, and can meet the elasticity requirements of the elastic film layer 5;

The casing 1 is provided with a camera through hole, an earphone through hole and a speaker through hole to ensure that the normal use of the mobile phone will not be affected during the charging process.
