the charging slide sheet 4 is provided with a lower charging surface 41 and a lower guide surface 42; the lower guide surface 42, one end of which transitions to the lower charging surface 41 and forms a height difference d with the other end; the power supply unit 2 is guided to contact and separate from the lower charging surface 41 via the lower guide surface 42.
This charging structure for the robot provides the function that the quick contact charges, through power supply unit 2 and the lower charge face 41 of the gleitbretter 4 that charges and the cooperation of guide face 42 down, realized providing the function of automatic charging for the robot, contact failure and the problem that need frequently dismantle the battery when having solved among the prior art and charging.
Specifically, as shown in fig. 1-3, the charging connecting arm 3 is used for connecting the robot main body 9, and the robot main body 9 can be suspended in the air, or moved on the ground, etc.; when the robot main body 9 needs to be charged, the robot main body drives the charging connecting arm 3 to move and drives the charging sliding sheet 4 to move; when the charging slide 4 moves, it passes through the power supply module 2 and contacts the power supply module 2 through the lower guide surface 42; one of the power supply component 2 and the charging slide 4 can be set as a support applicator, and the other one is a support receiver; after the support applicator contacts the support receiver, the support receiver is driven to move, so that the support receiver performs displacement change.
When the support applicator is the charging slide plate 4 and the support receiver is the power supply component 2, the lower guide surface 42 can support the power supply component 2 when the lower guide surface 42 keeps moving, the power supply component 2 moves to the lower charging surface 41 under the guide effect of the lower guide surface 42 with the height difference d at the two ends, the lower charging surface 41 is in plane contact with the power supply component 2, the contact area between the lower charging surface and the power supply component 2 is increased, the complete contact between the lower charging surface and the power supply component is ensured, and the charging stability of the robot is improved. When the power supply module 2 contacts the lower guide surface 42 or the lower charging surface 41, the power supply module 2 is electrically connected to the robot main body 9 through the charging slide 4, and the power supply module 2 charges the power supply of the robot main body 9. After the robot main body 9 is charged, the charging slide 4 moves continuously to be separated from the power supply assembly 2, and the power supply assembly 2 can reset under the action of gravity.
Similarly, when the support applicator is the power supply module 2 and the support receiver is the charging blade 4. The power supply unit 2 lifts the lower guide surface 42 to drive the charging slide 4 to displace itself, so that the power supply unit 2 contacts the lower charging surface 41 and the lower charging surface 41 is attached to the power supply unit 2.

Further, the upper guide surface 212 of the left end of the charging contact plate 21 moves along the lower charging surface 41 of the right end of the charging slide 4; that is, the relative movement between the charging slide 4 and the power supply unit 2 is caused by the upper guide surface 212 and the lower guide surface 42, and the relative movement between the upper charging surface 211 and the lower charging surface 41, so as to ensure that the lower charging surface 41 is charged after contacting the upper charging surface 211, thereby improving the charging stability of the robot main body 9.
The shape of the lower guide surface 42 is: a plane or an arc-shaped curved surface extending in a straight line while being inclined, and the height difference d of the curved surface changes to guide the upper guide surface 212 to move so that the lower charging surface 41 comes into contact with the upper charging surface 211.
