Flaw detection apparatus, wireless charging emitter, wireless charging receiver and vehicle

Abstract

The present invention discloses a flaw detection apparatus, a wireless charging emitter, a wireless charging receiver and a vehicle. The present invention discloses a flaw detection apparatus, which is arranged on the emission plate housing of the wireless charging emitter or the receiving plate housing of the wireless charging receiver, and comprises an ultrasonic wave emitter, a plurality of ultrasonic wave receivers and a controller, wherein the ultrasonic wave emitter is arranged on the corresponding housing and is used for transmitting ultrasonic wave signals to the edge of the housing through the housing, the ultrasonic wave receivers are arranged on the corresponding housing and are respectively used for receiving the ultrasonic wave signals and converting the ultrasonic wave signals into electrical signals, and the controller is respectively and electrically connected to the plurality of the ultrasonic wave receivers and is used for receiving the electrical signals of each ultrasonic wave receiver and judging whether the corresponding housing is normal according to the intensity of the electric signal. With the technical scheme of the present invention, the safety of the work of the wireless charging system can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a flaw detection device, a wireless charging transmitter, a wireless charging receiver and an automobile. Background technique [0002] At present, the charging of electric vehicles mainly adopts two methods: wired charging and wireless charging. When wireless charging, wireless charging transmitters and wireless charging receivers will be used. Take the wireless charging transmitter for cars as an example, and the wireless charging transmitter Buried in the ground, the launch board shell of the wireless charging transmitter on its surface is often subject to external mechanical damage, such as vehicle rolling, impact, heavy object impact and scratching, etc., which may cause damage to the launch board of the wireless charging transmitter. There are cracks in the casing. Once moisture seeps into the internal primary coil through the crack, it may cause a short circuit o...

Problems solved by technology

[0002] At present, the charging of electric vehicles mainly adopts two methods: wired charging and wireless charging. When wireless charging, wireless charging transmitters and wireless charging receivers will be used. Take the wireless charging transmitter for cars as an example, and the wireless charging transmitter Buried in the ground, the launch board shell of the wireless charging transmitter on its surface is often subject to external mechanical damage, such as vehicle rolling, impact, heavy object impact and scratching, etc., which may cause damage to the launch board of the wireless charging transmitter. There are cracks in the casing. Once moisture seeps into the internal primary coil through the crack, it may cause a short circuit or even a fire when the primary coil is working. At present, most of the faults are not checked until a fault occurs.

In short, as long as there is a crack on the launch board shell of the wireless charging transmitter, if the crack or other similar abnormalities cannot be found in time, it will increase the risk of the wireless charging system working
