Automatic charging device and method of automatically travelling cleaner
First Claim
1. An automatic charging device of an automatically traveling cleaner comprising:
- a charger having a power source terminal;
a contact sensor unit installed at an automatically traveling cleaner so as to be in contact with the power source terminal;
a charging terminal unit for slidably installed at the automatically traveling cleaner and selectively contacting the power source terminal; and
a charging terminal unit driving unit for selectively drawing in and out the charging terminal unit.

Abstract
An automatic charging device and method of an automatically traveling cleaner are disclosed. Since a charging terminal unit is installed inside a traveling cleaner and selectively drawn out, the traveling cleaner is prevented from being damaged from collision with an object while being moved forwardly. In addition, because a power source terminal, a contact sensor unit and a charging terminal unit are formed in a shape of a circular arc, the entering angle of the traveling cleaner widens, so that the charging induction time can be much reduced and the charging can be performed easily and quickly.

10. An automatic charging method of an automatically traveling cleaner, comprising:
-
a first step in which a traveling cleaner is approached toward a charger;
a second step in which a charging terminal unit is drawn out when a forward object is in contact with a contact sensor unit while the traveling cleaner is being approached;
a third step in which it is determined whether the forward object is the charger;
a fourth step in which if the charging terminal unit is electrically connected with the forward object, the forward object is recognized as a charger, and the traveling cleaner is charged; and
a fifth step in which if the charging terminal unit is not electrically connected with the forward object, the forward object is recognized as an obstacle, the charging terminal unit is returned to its original position, and the traveling cleaner is again approached toward the charger by avoiding the forward object.
