Abstract
Diversified opening and closing operations of a grille such as sequential or simultaneous operations enhance the sophistication of the opening and closing operations of the grille, contribute to the diversification of external design, and secure the airflow rate through the optimized structural arrangements. Furthermore, an external variable opening and closing apparatus that prevents jams and malfunctions of portions during the opening and closing operations of the grille to improve the reliability of the grille opening and closing operation is disclosed.
Claims19
An external variable opening and closing apparatus comprising:
- a housing including an opening portion;
- a flap unit provided in the opening portion to open or close the opening portion according to a tilting position of the flap unit in tilting in the housing;
- and
- a drive unit including a driver and an actuating member, wherein the actuating member is movably engaged to the housing and the flap unit is connected to the actuating member so that a tilting position of the flap unit switches in response to activation of the driver.
An external variable opening and closing apparatus comprising:
- a housing including a plurality of opening portions;
- a plurality of flap units movably provided in each opening portion to open or close each opening portion according to tilting positions of the flap units in tilting in the housing;
- and
- a plurality of drive units, each driver unit including a driver and an actuating member, wherein the actuating member is movably engaged to the housing and each flap unit is connected to the actuating member so that a tilting position of the flap units switches in response to activation of the driver.
An external variable opening and closing apparatus comprising:
- a housing including an opening portion;
- a flap unit including a panel portion and a moving shaft, wherein the panel portion opens or closes the opening portion according to a tilting position of the flap unit around the moving shaft;
- and
- a drive unit including a driver for generating power and an actuating member movably provided in the housing and including a plurality of guide holes with a straight or curved region, wherein the moving shaft of the flap unit is connected to the guide hole so that the tilting position of the flap unit switches in response to activation of the driver,
- wherein the guide hole in the actuating member includes a maintenance region and a tilting region and
- wherein an opening and closing timing of the opening portion is adjusted based on a length ratio or a shape of the maintenance region and the tilting region.
