Conversion system and device based on wireless charging
Technical Field
The invention relates to the technical field of wireless charging, in particular to a conversion system and device based on wireless charging.
Background
In modern society, the widespread popularity of electronic devices and the continual updating and upgrading of electronic devices make people put higher demands on charging technologies. The traditional wired charging mode has the problems of cable entanglement, charging port loss and the like, and brings a series of inconveniences to users, so that research and development of a more efficient and convenient wireless charging technology become particularly important. The background introduction will be around the challenges of charging electronic devices, the trend of wireless charging, and the popularity of Type-C interfaces.
With the rapid development of the mobile internet, various intelligent electronic devices such as smart phones, tablet computers, handheld devices and the like are widely used. However, the rapid popularity of these electronic devices also presents charging challenges. The traditional wired charging mode has the problems of cable entanglement, abrasion of a charging port, matching of a charging head and the like. In addition, the need for the user to carry different types of charging cord, compatibility between different devices, also becomes a headache problem.
In order to solve the inconvenience of wired charging, wireless charging technology has been developed. Wireless charging technology transmits energy between devices by means of electromagnetic induction, electromagnetic radiation, etc., so that the devices can be charged without using conventional charging wires. The charging experience of the user is greatly improved, the trouble of charging the cable is eliminated, and the abrasion risk of the charging port is reduced. Wireless charging technologies are classified into various types including electromagnetic induction, electromagnetic resonance, radio frequency energy transmission, and the like. Electromagnetic induction is one of the most widely used techniques at present, which transmits energy by means of an electromagnetic field between induction coils. The electromagnetic resonance technology transmits energy at a certain frequency through a resonance device, so that the electromagnetic resonance device has a larger charging distance and higher efficiency. The radio frequency energy transmission utilizes radio frequency signals to transmit energy, and is suitable for some special scenes.
The Type-C interface is a new generation interface standard which is pushed out by USB, has the advantages of reversible plug, high transmission speed, high-power charging support and the like, and is widely applied to electronic equipment. Compared with the traditional MicroUSB and MiniUSB interfaces, the Type-C interface is more convenient to plug, and a user does not need to worry about the problem of the plug-in interface. In addition, the Type-C interface also supports a fast charging technique, which can more quickly charge the device.
However, while the Type-C interface brings many advantages in terms of transmission and charging, the user still needs to plug in a charging cord, and some problems of wired charging are not completely solved. Therefore, a wireless charging technology and a Type-C interface are combined, a wireless charging-based conversion system and device are provided, and a more convenient and efficient charging scheme is provided for electronic equipment.
