Mechanism and method for actuating a charging flap
An electric vehicle ( 1 ) has a charging flap ( 10 ) articulated on a support structure by way of a four-bar linkage arrangement ( 14 ) so that the charging flap ( 10 ) can be moved between a closed position (FIG. 3 A) and an open position (FIG. 3 F). To simplify the actuation of the charging flap, the mechanism for actuating the charging flap ( 10 ) has a push-push element ( 20 ) combined with a spring device ( 15 ) that is assigned to the four-bar linkage arrangement ( 14 ).
1. A mechanism for actuating a charging flap ( 10 ), in particular of an electric vehicle ( 1 ), which charging flap ( 10 ) is articulated on a support structure by way of a four-bar linkage arrangement ( 14 ) in such a way that the charging flap ( 10 ) can be moved between a closed position ( FIG. 3A ) and an open position ( FIG. 3F ), characterized in that the mechanism for actuating the charging flap ( 10 ) comprises a push-push element ( 20 ) which is combined with a spring device ( 15 ) which is assigned to the four-bar linkage arrangement ( 14 ).
2. The mechanism as claimed in claim 1 , characterized in that the charging flap ( 10 ) is prestressed into its closed position ( FIG. 3A ) and its open position ( FIG. 3F ) by way of the spring device ( 15 ).
3. The mechanism as claimed in either of the preceding claims, characterized in that the spring device ( 14 ) has a spring dead center which is assigned a dead center position ( FIG. 4B , FIG. 5D ) of the charging flap ( 10 ), in which dead center position the charging flap ( 10 ) is arranged between its closed position ( FIG. 3A ) and its open position ( FIG. 3F ).
4. The mechanism as claimed in one of the preceding claims, characterized in that the charging flap ( 10 ) can be pivoted upward out of its closed position ( FIG. 3A ) into its open position ( FIG. 3F ).
5. The mechanism as claimed in one of the preceding claims, characterized in that, in its open position ( FIG. 3F ), the charging flap ( 10 ) is arranged above a charging opening ( 6 ).
6. The mechanism as claimed in one of the preceding claims, characterized in that the four-bar linkage arrangement ( 15 ) comprises two link pairs ( 31 , 32 ) which are articulated on two sides of the charging flap ( 10 ).
