Abstract

The invention discloses a wireless charging foreign matter removing device, a foreign matter removing method, electronic equipment and a storage medium. The device comprises a power supply module, a foreign matter removing module and a control module, wherein the foreign matter removing module is arranged above a ground end charging coil; the foreign matter removing module comprises a first surface structure and a third surface structure, the first surface structure is provided with a first electromagnetic driving part, and a second electromagnetic driving part is arranged at the position, corresponding to the first electromagnetic driving part, of the third surface structure; and when the power supply module is electrically connected with the first electromagnetic driving part and / or the second electromagnetic driving part, the first electromagnetic driving part and / or the second electromagnetic driving part intermittently generate electromagnetic force for driving the first electromagnetic driving part to be far away from the second electromagnetic driving part. Foreign matters in the wireless charging system are removed through electrical performance, the problem of spring aging is avoided, and the metal spring can be prevented from being 'heated' at the wireless charging ground end at the same time.

Description

Technical field [0001] The present invention relates to the field of automotive related technologies, particularly a wireless charging foreign matter cleaning device, a foreign matter cleaning method, an electronic device, and a storage medium. Background technique [0002] When the electric vehicle wireless charging function is started, there may be foreign matter between the power transmission unit of the wireless charging device, and foreign matter interference will result in a decrease in charging efficiency, but also for metal foreign matter, it will be affected by the magnetic field. Thus, there is a safe hidden danger such as smoky. [0003] Therefore, the prior art provides a wireless charging foreign matter cleaning device for cleaning the foreign matter on the wireless charging device. However, the existing wireless charge foreign matter cleaning device is coordinated by a spring and a motor to generate a mechanical vibration through a motor driving. Therefore, existing...
