Description

A hidden air vent utilizing a ball joint The present invention relates to a hidden air vent utilizing a ball joint, wherein the upper and lower air passages are provided to form a separated airflow toward the passenger compartment of the vehicle, connected to a main air passage through which temperature-controlled air is supplied from an HVAC unit of the vehicle, and the upper and lower air passages are installed with downward and upward angles so as to collide with each other to form a collision flow in front of a crush pad, and a plurality of left and right airflow direction control blades are installed in the upper and lower air passages to be simultaneously variable as a single knob that is installed to move horizontally on the crush pad. Generally, automobiles employ an air conditioning system to enable ventilation and adaptation to various climates. The air conditioning system provided in the vehicle serves purposes such as ventilation, heating and cooling, and defrosting, and multiple outlets are provided within the vehicle to supply cold or warm air to the interior. And, the vent grille device applied to the above air conditioning system is composed of a housing connected to an air duct and an air grille rotatably coupled to the housing, and the air grille is composed of a plurality of horizontal wing sections hinged together and a plurality of vertical wing sections located in front of the horizontal wing sections and formed vertically on the air grille, thereby controlling the horizontal and vertical directions of the wind. In relation to such technology, the technology of a vehicle air vent device is disclosed in the prior art patent No. 2294272, and as shown in FIG. 1, the configuration is such that air (A) flowing from the duct section (10) into the housing section (100) is installed to be discharged to the interior of the vehicle body along the lower surface of the second blade section (300) and the inner surface of the housing section (100). And, the second blade section (300) is arranged parallel to the first blade section (200), so that the air (A) discharged into the interior of the vehicle body through the first flow section (110) and the second flow section (120) is discharged in a straight line toward the occupant. Additionally, the second blade portion (300) is seated on a second seating portion (621) formed on a second guide body (620) that forms a guide portion (600), and air (A) is discharged through a first flow path portion (110) formed between the upper side of the first blade portion (200) and the inner side of the housing portion (100). Additionally, air (A) flowing from the duct section (10) into the housing section (100) passes through the second guide body (620) and the second flow path section (120) formed between the second guide body (620) and the inner surface of the housing section (100) facing the second guide body (620) and is discharged to the outside, and a guide cover section (630) is coupled to connect the first guide body (610) and the second guide body (620). In addition, the above Euro section and guide body are equipped with an elastic sealing section (710) (720) and installed so as to be able to contact the blade section. However, the above-described air vent device has a disadvantage in that the air cannot be concentrated because it is configured such that air is discharged in a straight line toward the occupant centered on the guide section or air (A) is discharged in a diffused manner between the blade section (200) and the guide body (610) depending on the operation of the blade section (200) (300) provided on the upper and lower sides of the guide section (600).
