Sofa with built-in wireless mobile phone charging device

Abstract

A sofa with a built-in wireless mobile phone charging device is characterized by comprising a radio frequency receiving module, a radio frequency emission module, an electric energy emitter and an electric energy receiver, wherein the electric energy emitter is connected with the electric energy receiver by an electromagnetic wave, the electric energy receiver is connected with the radio frequencyemission module, the radio frequency emission module is in wireless connection with the radio frequency receiving module, the radio frequency receiving module is connected with a power supply emitter, the electric energy emitter comprises a flat block-shaped first shell, a power interface, an emission circuit and an emission coil, the emission circuit and the emission coil are connected and are arranged in the first shell, the electric energy receiver comprises a second shell, a receiving circuit, a receiving coil, a charging controller and a charging interface, one end of the charging interface is connected with the receiving coil, a charging connector is arranged at the other end and is used for connecting a mobile phone, and the electric energy receiver and the electric energy emitterare embedded into the sofa. By the sofa with the built-in wireless mobile phone charging device, the problems that a traditional wired charger is trouble to charge and a charging line is not safe aresolved; meanwhile, an intelligent control switch of a wireless charger is achieved by wireless communication, the radio frequency emission module is used for sending a notice to the radio frequency receiving module when the mobile phone is connected with the electric energy receiver, the radio frequency receiving module is used for controlling on / off of the power emission module, so that the charger is more intelligent and convenient.

Description

technical field [0001] The invention relates to the field of smart phone accessories, in particular to a sofa built-in wireless mobile phone charging device. Background technique [0002] At present, the vast majority of mobile phone chargers use wires to charge mobile phones. The data lines are sometimes entangled, which brings inconvenience to life. At the same time, the repeated insertion and extraction of data lines into and out of the mobile phone charging port will cause damage to the mobile phone hardware. The charging method with the help of a data cable is simple, but people often do not unplug the charging cable when answering the phone when charging a mobile phone. During the call, due to the load of the electrical appliance, the output efficiency of the charger increases and the temperature rises.

Problems solved by technology

[0002] At present, most mobile phone chargers use wires to charge mobile phones. The data lines are sometimes entangled, which brings inconvenience to life. At the same time, the data lines are repeatedly inserted and pulled out of the mobile phone charging port, which will cause damage to the mobile phone hardware.

The charging method with the help of a data cable is simple, but people often do not unplug the charging cable when answering the phone when charging a mobile phone. During the call, due to the load of the electrical appliance, the output efficiency of the charger increases and the temperature rises. At this time, if the phone is used for a long time, It will lead to the increase of the load of the charger, which will cause damage to the thyristor and cause leakage, threatening human life.

In real life, the distance between the socket and the charging cable of the mobile phone is not long enough. People hope that the mobile phone can be charged in time when the battery is low during rest.
