Mobile phone charging back clip and rechargeable battery

technical field

The invention belongs to the technical field of mobile phone accessory manufacturing, and relates to the improvement of a mobile phone back clip with a replaceable rechargeable battery, in particular to a mobile phone charging back clip and a rechargeable battery.

Background technique

With the popularity of large-screen smartphones, the contradiction of short standby time of mobile phones has become increasingly prominent. Generally, the standby time of mobile phones will be greatly shortened after about one year of use, and frequent charging, sometimes requiring two charges a day, brings troubles to users. It has a built-in battery, and the battery cannot be replaced. If the mobile phone worth thousands of yuan is replaced, it will cause a lot of economic loss to the user, and the user has just been familiar with the various functions of the mobile phone, and changing a new mobile phone will bring great inconvenience to the user. Therefore, portability is

Power banks for mobile phone charging and mobile phone charging back clips with charging functions have emerged as the times require.

At present, there are many mobile phone charging back clips with charging functions on the market, which are mainly composed of a mobile phone cavity, a rechargeable battery, and a charging circuit component. Usually, the mobile phone cavity is provided with a charging interface for charging the rechargeable battery and the mobile phone. The microphone hole of the sound, the sound output hole, the power button hole of the mobile phone and the volume button hole of the mobile phone are used for operating the mobile phone. These mobile phone charging back clips are integrated. When installing the mobile phone, it is generally necessary to open the back clip forcefully and then press the mobile phone in; there are also split types, usually with a detachable top cover on the top of the mobile phone charging back clip. , The separation methods of the top cover are slideway type and buckle type, and the split back clip is convenient for installing and removing the mobile phone. However, the rechargeable batteries in these mobile phone charging back clips are also directly fixed in the mobile phone charging back clip and integrated with the mobile phone charging back clip. The mobile phone charging back clip and the mobile phone are charged, and the charging time is relatively long. When you encounter this situation when you go out, you need to find a power base to charge, otherwise the mobile phone cannot be used, which brings inconvenience to the user, and even delays important affairs or causes heavy losses. In addition, the service life of each rechargeable battery cell is limited. When the life of the rechargeable battery cell in the mobile phone charging back clip is over, because it cannot be replaced, the mobile phone charging back clip and the rechargeable battery in it will be scrapped together.

This creates a lot of waste.
