Dual-mode wireless charging device and dual-mode wireless charging mobile phone shell

Abstract

The invention discloses a dual-mode wireless charging device, which comprises a wireless charging PCBA plate, a magnetic suction USB connector and a magnetic suction USB data wire, wherein the magnetic suction USB connector is electrically connected to the wireless charging PCBA plate; the magnetic suction USB data wire can be adsorbed to and electrically connected to the rear side of the rear end of the magnetic suction USB connector; the wireless charging PCBA plate comprises a wireless charging receiving coil and a PCBA plate; the PCBA plate is electrically connected with the wireless charging receiving coil; the PCBA plate is electrically connected to the front side of the rear end of the magnetic suction USB connector; and the front end of the magnetic suction USB connector is used for being inserted into a USB interface of to-be-charged equipment. The invention further discloses a dual-mode wireless charging mobile phone shell, which comprises the wireless charging PCBA plate, the magnetic suction USB connector and the magnetic suction USB data wire; the wireless charging PCBA plate is applied to the inner side of the mobile phone shell; the magnetic suction USB connector is electrically connected to the wireless charging PCBA plate; and the magnetic suction USB data wire can be adsorbed to and electrically connected to the rear side of the rear end of the magnetic suction USB connector. Therefore, the functions of a wireless charging receiving patch and the magnetic suction USB data wire are fused; and free transformation of wireless charging and wired charging and data transmission can be easily carried out on the electronic products of a mobile phone and the like without the USB connector.

Description

Technical field [0001] The invention relates to the field of wireless power transmission, in particular to a dual-mode wireless charging device and a dual-mode wireless charging mobile phone case that integrate wireless power transmission and magnetic attraction technologies. Background technique [0002] The wireless power supply technology is powered by a non-physical contact. As the technology matures, it has received more and more attention and recognition from the society, which greatly facilitates the use of wireless products. [0003] However, taking the low-power, mobile phone wireless charging receiving patch (shell) as an example, the current wireless charging receiving patch (shell) uses the only USB charging port of the mobile phone as the access point, and the wireless charging can receive power input after matching. ; In this way, the mobile phone cannot perform data transmission and wired charging. When data transmission and wired charging are required, the wireless ...

Problems solved by technology

[0005] Aiming at the defects of the existing technology, the present invention designs a dual-mode wireless charging device, which can freely choose to use three modes of wireless charging, magnetic adsorption wired charging, and magnetic magnetic adsorption wired data transmission for charging and data transmission according to needs, overcoming In the prior art, frequent plugging and unplugging of the charging connector easily causes damage to the charging and receipt interface. Without plugging and unplugging the connector, the free conversion between wireless charging and wired charging of electronic products such as mobile phones can be easily realized. At the same time, wired charging between electronic products can also be easily realized. Data transmission requirements, good customer experience
