The invention belongs to the technical field of wireless power supply, and particularly relates to a wireless power supply device, mobile equipment and a conveying system. The wireless power supply device only needs to be equipped with a set of transmitting device, one side of a transmitting coil located at a fork road or a switching track can be interrupted or lost due to avoiding the operation of the wireless electric energy receiving device, and when the wireless electric energy receiving device passes through the fork road or track switching, the wireless electric energy receiving device is switched. The magnetic field coupling on one side of the missing transmitting coil is weakened and loses the power taking capability, and the transmitting coil on the other side and the wireless electric energy receiving device are still in a normal coupling state, so that a stable electromagnetic field can be formed, electric energy can be obtained, and uninterruptible power supply is ensured. The problem that the electricity taking capacity of an existing electricity taking device is rapidly reduced when the current electricity taking device passes through a fork or is switched through a rail is solved. And only one set of launching device is needed, so that the cost is greatly reduced, and the mounting space is saved.
本发明属于无线供电技术领域,尤其涉及一种无线供电装置、移动设备及输送系统。该无线供电装置仅需配备一套发射装置,其中,位于岔路口或切换轨道处的发射线圈一侧因避让无线电能接收装置运行会出现中断或缺失,当无线电能接收装置经过岔路口或轨道切换时,发射线圈缺失的一侧磁场耦合变弱而丧失取电能力,而另一侧发射线圈与无线电能接收装置依然处于正常耦合状体,可形成稳定的电磁场,并获取到电能,保证不断电。解决了现有取电器在过岔路口或轨道切换时,取电能力急速下降的问题;并且仅需一套发射装置,大大降低了成本,节省了安装空间。
