Problems solved by technology

The transmitting coils used to emit electromagnetic waves on the existing wireless charging base are basically fixed on the base, which leads to the need to find the correct position when the device to be charged is placed on the base. Once the position deviates, the charging efficiency will decrease. will be reduced, seriously affecting the user experience

Embodiment Construction

[0028] In this embodiment, the device to be charged is charged based on the wireless charging technology. The wireless charging technology does not require cables to complete power transmission, which can simplify the operation of the charging preparation phase.

[0029] The wireless charging technology needs to connect the power supply equipment (such as adapter) with the wireless charging device (such as wireless charging base), and transmit the output power of the power supply equipment wirelessly (such as electromagnetic signal or electromagnetic wave) through the wireless charging device. The device to be charged is charged wirelessly. According to different principles of wireless charging, wireless charging methods can be divided into three methods: magnetic coupling (or electromagnetic induction), magnetic resonance, and radio waves. The specific wireless charging standards used may include: QI standard, power matters alliance (PMA) standard, and wireless power alliance (a...

Abstract

The invention provides a wireless charging device, a wireless charging system and a wireless charging method. The wireless charging device comprises a working panel, a transmitting coil, a base, a fixed guide rail and a driving device, wherein the fixed guide rail is fixed relative to the base, the working panel is movably connected with the base, and the driving device is connected with the transmitting coil and the working panel; the working panel is used for placing to-be-charged equipment provided with a receiving coil; the transmitting coil is used for transmitting an electromagnetic signal to wirelessly charge the to-be-charged equipment; the driving device is used for driving the transmitting coil to move along the fixed guide rail and driving the working panel to move relative to the base. According to the wireless charging device provided by the invention, the transmitting coil is driven to move along the fixed guide rail fixedly arranged on the base of the wireless charging device and / or the working surface is driven to move relative to the base, so that the receiving coil is aligned with the transmitting coil, the charging efficiency can be effectively improved, and theuser experience is further improved.

Description

Technical field [0001] This embodiment relates to the field, and more specifically, to a wireless charging device, a wireless charging system, and a wireless charging method. Background technique [0002] At present, in the field of charging technology, the equipment to be charged is mainly charged by a wired charging method. [0003] Take a mobile phone as an example. When you need to charge a mobile phone, you can connect the mobile phone to the power supply device through a charging cable (such as a universal serial bus (USB) cable), and provide power through the charging cable The output power of the device is transmitted to the mobile phone to charge the battery in the mobile phone. [0004] However, with the popularity of wireless charging, more and more electronic devices support functions such as wireless charging or wireless transmission, and wireless charging methods are becoming more and more popular. The transmitting coils used to transmit electromagnetic waves on the e...
