Referring to fig. 3, the embodiment of the present application further discloses a robot charging system capable of automatically charging, which includes a robot and the above bottom-contact charging pile adapted to the robot. The robot comprises a machine shell 6 and two charging contacts 7 fixed on the machine shell 6, wherein the two charging contacts 7 are arranged at intervals along the butt joint direction.

Referring to fig. 2 and 3, the charging contact 7 has a rectangular plate shape, the width direction of the charging contact 7 coincides with the mating direction, and the length direction of the charging contact 7 is perpendicular to the mating direction. The length of the charging contact 7 is greater than the length of the plate 5 so that the charging contact 7 can still be in contact with the plate 5 when the charging contact 7 is displaced in a direction perpendicular to the mating direction, and the length of the charging contact 7 is preferably twice the length of the plate 5 in this embodiment.

After the robot is successfully butted, the width of the charging contact 7 is larger than that of the pole plate 5 due to the fact that a braking distance exists between the inertia of the robot and the inertia of the motor, and the robot can still be in contact with the pole plate 5 after moving over the braking distance.

After the robot finishes charging, the robot retreats along the opposite direction of the butting direction, and the charging contact 7 is not separated from contact with one polar plate 5 and is also contacted with the other polar plate 5, so that the two polar plates 5 are in short circuit, and the interval between the two polar plates 5 is larger than the width of the charging contact 7, thereby being beneficial to reducing the short circuit between the two polar plates 5.
