[0002] An automated guided vehicle, also known as an AGV, is an unmanned automated vehicle that uses a rechargeable battery as energy and is automatically guided. Under the monitoring of a computer, it can accurately walk and stop at a designated location according to path planning and work requirements to complete a series of work tasks. Patent application number 202020206858.4 discloses a wireless charging device for an automated guided vehicle, which includes a pressure sensor, a timer, a wireless charging transmitter, a mobile platform, a first reflective photoelectric sensor, a second reflective photoelectric sensor, a reflector, and a controller, wherein the pressure sensor is electrically connected to the timer, and the timer is electrically connected to the controller; the wireless charging transmitter and the second reflective photoelectric sensor are both arranged on the mobile platform, and the mobile platform is electrically connected to the controller. When the AGV needs to be charged, the wireless charging device applied to the automatic guided vehicle starts working; when the AGV does not need to be charged, the wireless charging device applied to the automatic guided vehicle is in offline mode, and will not generate electromagnetic waves, nor will it interfere with or radiate the surrounding environment of the automatic guided vehicle. However, although the existing wireless charging devices for automatic guided vehicles are becoming more and more intelligent and technologically advanced, the wireless charging devices are not convenient for positioning the automatic guided vehicle during use. Therefore, the automatic guided vehicle is prone to unexpected movement during the charging process, which will affect the normal charging of the automatic guided vehicle. For this reason, we propose a wireless charging device for an automatic guided vehicle. Utility Model Content
