Wireless charging device and system

Abstract

The invention discloses a wireless charging device and system, and the device comprises at least one electromagnetic wave transmitter which is configured to transmit electromagnetic waves in a working region of the wireless charging device; the device also comprises a first electromagnetic induction module which is laid on the ground of the working area and is configured to convert electric energy into magnetic energy; the first electromagnetic induction module comprises a plurality of first electromagnetic induction coils, the front end of each first electromagnetic induction coil is provided with a receiver, the receivers are used for receiving electromagnetic waves emitted by the electromagnetic wave emitter, and the receivers are further connected to a power supply circuit, so that the power supply is used for converting electromagnetic waves received by the receivers into direct current and supplying power to the first electromagnetic induction coil. According to the technical scheme provided by the embodiment of the invention, the electromagnetic induction technology and the radio wave technology are combined for wireless charging, and the two charging modes make up each other, so the charging device can meet the requirements of long-distance and high-power charging, and can realize the charging function in a working area.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a wireless charging device and system. Background technique [0002] The materials in the fully automated intelligent production line rely on the production line robots for handling, production and transfer. However, due to the limitation of battery power, the robot needs to return to the charging pile for power replenishment from time to time, which results in increased costs and reduced efficiency. question. [0003] The limitations of traditional wireless charging methods are very high. For example, although the radio wave charging method can transmit more than 10 meters from a relatively long distance, the power is small and the loss is large during the transmission process, which cannot meet the charging power requirements of the handling robot; Although the magnetic induction wireless charging method has relatively high power, the transmission distance is small, and it can...

[0002] The materials in the fully automated intelligent production line rely on the production line robots for handling, production and transfer. However, due to the limitation of battery power, the robot needs to return to the charging pile for power replenishment from time to time, which results in increased costs and reduced efficiency. question

[0003] The limitations of traditional wireless charging methods are very high. For example, although the radio wave charging method can transmit more than 10 meters from a relatively long distance, the power is small and the loss is large during the transmission process, which cannot meet the charging power requirements of the handling robot; Although the power of the magnetic induction wireless charging method is relatively high, the transmission distance is small, and it can only guarantee reliable charging within 10 cm

[0004] Therefore, the shortcomings of traditional wireless charging technology are very obvious: long-distance energy transmission cannot be achieved, the charging method can only be point-to-point (1VS.1), huge power loss during transmission, and low charging efficiency.
