[0043] An Automated Guided Vehicle (AGV) is a transportation device that can travel along a preset route and is widely used in the logistics and warehousing fields. Automated guided vehicles usually use rechargeable batteries as the power source to control the usage cost. In the traditional technology, the automated guided vehicle replenishes electrical energy through wired charging. However, the cable layout will occupy the storage space, affect the normal operation of the automated guided vehicle, and at the same time bring the risk of explosion and fire.

[0044] In the related technology, in order to adapt to some scenarios with higher requirements for explosion-proof grades, some AGV products use wireless charging to achieve electrical energy replenishment, getting rid of the cable bondage of the wired charging form and improving safety. However, this wireless charging mostly realizes electrical energy transmission through a contact form. On the one hand, it has high requirements for the positioning accuracy of the contacts, resulting in cumbersome positioning work in the early stage of charging; on the other hand, there are still problems such as easy wear and damage at the interface of this contact charging, the risk of arcing and ignition caused by poor contact of the charging head, and charging abnormalities caused by contact oxidation.

[0045] In order to solve the problems of the prior art, the embodiments of the present application provide an automatic guided vehicle and an automatic guided vehicle charging system.

The mobile device 100 can drive the power device and the receiving component 220 to move to a specified position so that the receiving component 220 can be docked with an external power source, thereby realizing contactless wireless charging of the automatic guided vehicle 10, reducing the safety risks of contact charging, and extending the service life of the power device. In addition, the mobile device 100 is provided with a shielding cover 130, which separates the receiving component 220 from other magnetic metal components in the automatic guided vehicle 10, thereby improving the charging conversion rate while reducing the heat generated by other magnetic metal components, thereby extending the service life of other magnetic metal components.

[0054] In some embodiments, the moving device 100 further includes a rib provided on the outer side of the housing along the circumferential direction of the housing. When the moving device 100 collides with the external environment, the rib can contact the external environment first to protect the housing and the components inside the housing.

[0055] Please refer to Figure 2 According to some embodiments of the present application, the shielding cover 130 includes a back plate 131 disposed opposite to the housing. Along the second direction, both ends of the shielding cover 130 extend towards the housing to form side plates 132.

[0070] It can be understood that in some other embodiments, the traveling assembly includes a driving unit 121 and a steering unit to respectively realize the speed adjustment and direction adjustment of the automatic guided vehicle 10, which will not be elaborated here.
