Description

Vehicle intake apparatus The present invention relates to an intake device for a vehicle, and more specifically, to an intake device for a vehicle that can improve temperature control performance inside the vehicle by blocking interference between outside air and inside air entering from the outside and inside of the vehicle. Generally, air conditioning systems are devices designed to maintain a comfortable indoor environment by controlling the temperature, humidity, and circulation of indoor air. They are primarily applied inside buildings or vehicles to regulate temperature and improve indoor air quality. Such systems are installed in vehicles to maintain the interior at an appropriate temperature or to ensure clear visibility while driving by compensating for temperature and humidity differences between the inside and outside of the vehicle. Vehicle air conditioning systems cool or heat the vehicle interior by using indoor and outdoor air to cool or heat it through heat exchange, and then supplying it to the vehicle interior. Such vehicle air conditioning systems are equipped with blowers to draw in air from the vehicle interior or exterior, and the blowers are equipped with intake devices to selectively open or close the inflow of indoor or outdoor air. Meanwhile, in recent years, there has been a continuous demand for research to improve the performance of blowers for vehicles even during high-speed driving. FIG. 1 is a cross-sectional perspective view schematically illustrating an intake device of a vehicle according to a preferred embodiment of the present invention. FIG. 2 is a side view schematically illustrating the state in which outside air is introduced into the intake device of a vehicle according to one embodiment shown in FIG. 1. FIG. 3 is a side view schematically illustrating the state in which outside air and inside air are mixed in an intake device of a vehicle according to an embodiment shown in FIG. 1. And, FIG. 4 is a side view schematically illustrating the state in which internal air is introduced into the intake device of a vehicle according to one embodiment shown in FIG. 1. Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. However, the concept of the present invention is not limited to such an embodiment, and the concept of the present invention may be proposed differently by adding, changing, or deleting components constituting the embodiment, and such are also included within the concept of the invention. Referring to FIG. 1, an intake device (1) of a vehicle according to a preferred embodiment of the present invention includes a body part (10), a first door part (20), and a second door part (30). As illustrated in FIG. 3, the body portion (10) is provided in the path of the outside air (F) and the inside air (R) so that the outside air (F) from outside the vehicle and the inside air (R) from inside the vehicle are introduced. This body portion (10) includes an intake body (11) in which an outside air inlet (12) and an inside air inlet (13) are formed adjacently through, and an outlet (14) through which the outside air (F) and the inside air (R) are discharged is formed at a position facing the outside air inlet (12). Here, at least one part of the inside air inlet (13) may be formed through the intake body (11) so as to face the outlet (14). An outside air grille (15) and an inside air grille (16) are installed at the outside air inlet (12) and the inside air inlet (13), respectively, to filter the incoming outside air (F) and inside air (R). Meanwhile, although not shown in the drawing, the body portion (10) may be connected to a blower that induces the inflow of outside air (F) and inside air (R) by having a predetermined suction means such as an impeller. Here, the outlet (14) of the body portion (10) is connected to a blower (not shown), and a filter (not shown) for filtering foreign substances from the outside air (F) and inside air (R) may be interposed in the outlet (14). The first door section (20) slides along the inner surface of the body section (10) to selectively open and close the outside air inlet (12). To this end, the first door section (20) includes a first door (21) and a connecting link (22) to control the rate of inflow of outside air (F) within the opening and closing range of the outside air inlet (12). The first door (21) is provided with an area capable of covering the outside air inlet (12). In this embodiment, the first door (21) is illustrated and exemplified as a plate with a curved shape having curvature, but this is not a limitation. Meanwhile, as illustrated in FIGS. 2 and 3, the first door (21) has both ends inserted into a sliding slot (21a) provided parallel to the outside air inlet (12) on the inner surface of the intake body (11), thereby guiding the sliding movement. This sliding slot (21a) can correspond to the sliding trajectory of the first door (21). One end of t
