Description

Active Air Flap Device for Vehicle The present invention relates to an active air flap device for a vehicle, and more specifically, to an active air flap device for a vehicle that opens and closes the opening of a radiator grille of a vehicle. Generally, a radiator grille is installed at the front of the vehicle to allow air to be introduced into the engine compartment of the vehicle, and the air introduced through the radiator grille is used to cool various coolers such as radiators. However, when a vehicle travels at high speed, the airflow entering the engine compartment through the radiator grille acts as resistance to the vehicle's movement. To address this, active air flaps that open and close the radiator grille are being applied recently. Conventional active air flaps operated simply to open and close the radiator grille, which resulted in a problem where structural stability was compromised as the flap would be pushed when aerodynamic or external forces were applied to it. In particular, as the flap operates to close the radiator grille when the vehicle is traveling at high speed, significant aerodynamic and external forces act on the flap during closure; therefore, a structure is required to prevent the flap from sliding in this situation. In addition, conventional active air flaps had the problem of reduced product reliability and structural stability because they could not detect operational errors.

Fig. 4 is a side view of Fig. 1. Figure 5 is a cross-sectional view of Figure 1. Fig. 6 is an exploded perspective view of Fig. 1. FIGS. 7 to 9 are operation diagrams for explaining the opening and closing operation of an active air flap device for a vehicle according to an embodiment of the present invention. Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. This is not intended to limit the present invention to specific embodiments, and should be interpreted to include all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. In describing the present invention, terms such as "first," "second," etc., may be used to describe various components, but said components may not be limited by said terms. Such terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. The term "and/or" may include a combination of multiple related listed items or any of the multiple related listed items. When it is stated that one component is "connected" or "connected" to another component, it can be understood that while it may be directly connected or connected to that other component, there may also be other components in between. On the other hand, when it is stated that one component is "directly connected" or "directly connected" to another component, it can be understood that there are no other components in between. The terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions may include plural expressions unless the context clearly indicates otherwise. In this application, terms such as “comprising” or “having” are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not excluding in advance the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.
