The invention discloses a wireless charging foreign matter detection device which comprises a processor and further comprises a detection module communicated with the processor; the detection module at least comprises a detection assembly, a power assembly, a transmitting antenna, a receiving antenna and a change-over switch; the transmitting antenna is communicated with the detection assembly, and the receiving antenna is selectively communicated with one of the detection assembly and the power assembly through the change-over switch; the transmitting antenna transmits detection electromagnetic waves, and the detection electromagnetic waves can be reflected to form echo signals when reflectors exist; when the receiving antenna is communicated with the detection assembly, an echo signal is received; when the receiving antenna is communicated with the power assembly, the radiation electromagnetic waves are received. The wireless charging foreign matter detection device can detect the existence of the foreign matter, and can judge whether the foreign matter causes potential safety hazards to wireless charging or not. And if no potential safety hazard exists, normal charging can be carried out even if foreign matters exist, so that the detection efficiency is high, and meanwhile, the efficiency of wireless charging work is ensured.
本发明公开了无线充电异物检测装置,包括处理器,还包括:检测模块,与处理器联通;检测模块至少具有:探测组件、功率组件、发射天线、接收天线和切换开关;发射天线与探测组件联通,接收天线通过切换开关在探测组件和功率组件中择一地联通;发射天线发射探测电磁波,探测电磁波在有反射物时,会被反射形成回波信号;接收天线与探测组件联通时,接收回波信号;接收天线与功率组件联通时,接收辐射电磁波。本发明的无线充电异物检测装置能够检测到异物的存在,同时能够判断该异物是否对无线充电造成了安全隐患。如果没有安全隐患,即使存在异物也可以正常进行充电,不仅检测效率高,同时保证了无线充电工作的效率。
