Abstract

The utility model provides a magnetic charging structure and an educational robot, wherein the magnetic charging structure comprises a first connector and a second connector which are used for being connected with each other, the first connector comprises a first shell, a first electric contact exposed out of the first shell and a first magnetic attraction piece arranged on the first shell, the first shell is provided with a fool-proof groove, the second connector comprises a second shell, a second electric contact and a second magnetic attraction piece, the second electric contact is arranged on the second shell in a protruding mode, the second magnetic attraction piece is arranged on the second shell in a protruding mode, and the fool-proof protrusion is arranged on the protrusion of the second shell and is higher than the protrusion height of the second electric contact. According to the magnetic charging structure and the educational robot, the connection direction of the first connector and the second connector is limited through the mutual matching of the fool-proof structure, and the reverse insertion of the connectors is prevented. Moreover, the height of the fool-proof bulge is larger than that of the bulge of the second electric contact, and when the second magnetic attraction piece adsorbs the ironwork, the ironwork can be stopped, so that the ironwork is prevented from conducting the second electric contact.
