Mobile phone charging device and mobile phone protection shell

Abstract

The invention relates to a mobile phone charging device and a mobile phone protection shell. The mobile phone charging device comprises a processing module, a voltage stabilization module, a USB female port and a USB male head, wherein the processing module is electrically connected with a touch panel; the voltage stabilization module is electrically connected with the processing module and is used for supplying power for the processing module; the USB female port is electrically connected with the processing module and is used for being connected with an adapter; and the USB male head is usedfor being connected with a mobile phone, and the USB male head is electrically connected with the processing module so as to realize USB communication between the processing module and the mobile phone and to charge the mobile phone. According to the mobile phone charging device, the free switching function of a charging circuit is realized, and external circuit charging cannot be influenced, andthe external charging circuit can be switched by enabling the USB female head to be inserted into the external adapter, so that the operation of a user is facilitated, and the use satisfaction degreeof the user is improved.

Description

technical field [0001] The invention relates to the technical field of circuit design, in particular to a mobile phone charging device and a mobile phone protective case. Background technique [0002] At present, with the progress and development of science and technology, the current smart phones have been widely promoted, and almost everyone has a smart phone in their hands. In the use of smart phones, their intelligence has brought great convenience to people. , but the current smartphones have a great disadvantage, that is, the battery life of the smartphone is short and needs to be charged repeatedly, that is, it needs to be charged at least once a day, so as to meet the user's requirements, and for some smartphones As far as mobile phones are concerned, the battery life is relatively short, and even more than two charging times are required in one day. [0003] In the traditional technology, the usual mobile phone case basically does not have the charging function. Ev...

[0002] At present, with the progress and development of science and technology, the current smart phones have been widely promoted, and almost everyone has a smart phone in their hands. In the use of smart phones, their intelligence has brought great convenience to people. , but the current smartphones have a great disadvantage, that is, the battery life of the smartphone is short and needs to be charged repeatedly, that is, it needs to be charged at least once a day, so as to meet the user's requirements, and for some smartphones As far as mobile phones are concerned, the battery life is even shorter, and even needs to be charged more than twice a day.

[0003] In the traditional technology, the usual mobile phone case basically does not have the charging function. Even if it has the charging function, it cannot realize the free switching between the external charging circuit and the internal charging circuit when charging the mobile phone, which greatly reduces the satisfaction of users.
