Static wireless charging method and device for mobile robot

Abstract

The invention discloses a static wireless charging method and a static wireless charging device for a mobile robot. The device comprises a ground transmitting end and a vehicle-mounted receiving end;the ground transmitting end is installed in a static charging area of the mobile robot, and the vehicle-mounted receiving end is installed on the mobile robot. The ground transmitting end is used forconverting electric energy into a high-frequency current to generate a high-frequency electromagnetic field around a coil through a transmitting coil; a receiving coil in the high-frequency electromagnetic field and a capacitor in a receiving system induct a high-frequency current in a magnetic coupling resonance mode; the rectification, filtering and voltage regulation are completed through an internal circuit of a receiving system to generate a voltage type needed by a vehicle-mounted receiving end to be used by a charging management system and charge energy storage equipment, and then the energy storage equipment supplies power to electric equipment. The invention further discloses an electric energy transmission method of the wireless charging device for the mobile robot. By adopting the technical scheme that the two transmitting coils are connected in series, it is guaranteed that the receiving coil can keep constant power and efficiency output at the preset position within a certain deviation range, and the safe, stable, reliable and efficient wireless transmission of electric energy is achieved in a magnetic coupling resonance mode.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a static wireless charging method and device for a mobile robot. Background technique [0002] With the development of economy and society and the advancement of artificial intelligence technology, the self-control ability of mobile robots is getting stronger and higher, and the level of intelligence is getting higher and higher. However, the power required by mobile robots is mainly provided by their own batteries, and the battery life is limited. When the battery power is low, the robot needs to move to a fixed charging area and use the wired charging pile to charge. Because the wired charging pile covers a large area, plugging and plugging the charging connector is easy to generate sparks and leakage accidents, and manual plugging and plugging of the charging connector reduces the robot's The intelligent level of mobile robots has become a weak link in improving the ...

Problems solved by technology

If wireless charging is used to charge the mobile robot statically, there are still some problems in the existing wireless charging technology: for example, the patent No. 201410300222.5 discloses a magnetically coupled resonant wireless charging platform, which can achieve magnetic Coupled resonant wireless charging, but it still cannot overcome the problem of the drop in transmission efficiency caused by the change of coil position

The patent No. 201811642358.9 discloses a wireless charging system for electric vehicles and its control method. This method needs to adjust the wireless charging transmitting board so that its position and spacing are better matched with the wireless charging receiving board to make the charging effect better. It means that there is a problem of poor anti-offset ability
