Description

A mobile phone with a convenient charging device

technical field

The utility model relates to a mobile phone, in particular to a mobile phone with a convenient charging device.

Background technique

Mobile phones are a common communication tool for people.

Detailed ways

The idea of the utility model to solve the technical problem is to integrate a charger on the mobile phone, so that it can be charged in time when the mobile phone is out of power, and is convenient to carry.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the utility model.

As shown in Fig. 1 and Fig. 2, the mobile phone of this embodiment includes a charger, the power plug of the charger is hidden in the back of the mobile phone, and can be rotated and ejected. The state when the power plug is hidden is shown in Figure 1, and the state when it is rotated and ejected is shown in Figure 2.

As shown in Fig. 3 and Fig. 4, the mobile phone of this embodiment includes a charger, and the power plug of the charger is hidden in the back of the mobile phone and can be rolled out. The state when the power plug is hidden is shown in Figure 3, and the state when it is pushed out is shown in Figure 4.

The circuit principles of the above two embodiments are shown in Figure 5, the power plug, transformer, voltage stabilizing circuit, rectifying circuit, overcharge protection circuit and mobile phone battery are electrically connected in sequence. The power plug that rotates and pops up or is pushed out is inserted into the mains socket, and the power is turned on. The transformer reduces the mains voltage to the voltage applicable to the mobile phone, and then outputs it to the rectification circuit after being regulated by the voltage stabilizing circuit. The rectification circuit rectifies the alternating current into DC power is input to the mobile phone battery through the charging protection circuit. The voltage stabilizing circuit, the rectifying circuit and the overcharge protection circuit are collectively referred to as the charging circuit. The overcharge protection circuit can automatically cut off the charging circuit when the battery is full to protect the battery of the mobile phone.

The utility model can also be charged with a USB interface. One embodiment is to integrate the USB charging port with the earphone of the mobile phone. As shown in Figure 6, a USB connector is arranged in the middle of the wire of the earphone, and the USB connector is divided into USB plugs. and USB socket, the USB plug connects to the headphone plug side, and the USB socket connects to the earbud side of the headset. The mobile phone is provided with an earphone socket adapted to the earphone plug, and the earphone socket is provided with a detection and separation circuit. The detection and separation circuit includes a charging output terminal connected to the battery of the mobile phone and a sound signal output terminal connected to the sound processing module of the mobile phone. The detection separation circuit detects the current signal coming from the earphone side, if it is a sound signal, it is output to the sound processing module; if it is a charging current, it is output to the mobile phone battery to charge the mobile phone. When the mobile phone is out of power, the USB plug of the USB connector can be inserted into the USB interface of the computer to charge the mobile phone. For more convenient use and higher integration, the microphone of the headset can be set at the position of the USB connector.
