KR-20260065652-A - An apparatus for driving of electric air vents with saving space

Abstract

The present invention relates to a technology that allows the angle of an air vent wing to be adjusted by converting the rotational motion of a motor into linear motion of a driving means connected thereto, and the driving means is made flexible so that it can be variable, thereby minimizing the installation space of the driving means, and thus relates to an installation space-saving electric air vent driving device.

Description

An apparatus for driving electric air vents with saving space The present invention relates to a technology that allows the driving means connected thereto to convert rotational motion of a power shaft into linear motion to adjust the angle of an air vent wing, and the driving means is configured to have variable flexibility so as to minimize the installation space of the driving means, thereby providing an installation space-saving electric air vent driving device. 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 the electric air vent device of the prior art patent No. 2598528 is presented, and its configuration is provided as shown in FIG. 1, having at least one horizontal wing that rotates up and down, and comprises a horizontal wing module (200) mounted on the air outlet of an air duct (100), a motor (110) mounted on the outer surface of the air duct (100), a control module (300) that applies a driving signal to the motor, a first link (120) connected to the output shaft of the motor so as to be rotatable up and down, and a second link (130) whose front end is hinge-connected to the horizontal wing module (200), whose rear end is hinge-connected to the first link (120), and whose middle part between the front end and the rear end is hinge-connected to the outer surface of the air duct, thereby rotating the horizontal wing of the horizontal wing module (200) up and down in conjunction with the rotational movement of the first link (120). However, the above-mentioned electric air vent device has the disadvantage of being connected by multiple parts, including a link connecting the wing and the power unit that rotates the wing, which makes manufacturing or repair difficult, takes up a lot of space, and imposes restrictions on design configuration. FIG. 1 is a drawing illustrating a conventional electric air vent device. FIG. 2 is a diagram comparing the present invention with a general driving method. FIG. 3 is a perspective view illustrating an air vent driving device according to the present invention. FIGS. 4 and 5 are perspective views illustrating the main parts of an air vent driving device according to the present invention. FIG. 6 is a side view illustrating the operating state of an air vent driving device according to the present invention. FIGS. 7 and 8 are schematic diagrams illustrating an air vent driving device according to another embodiment of the present invention. FIG. 9 is a schematic diagram illustrating the operating state of an air vent driving device according to another embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail based on the attached drawings. As illustrated in FIGS. 2 to 9, the driving device (A) of the present invention is configured with one or more wings (400) installed to rotate horizontally or vertically in the discharge port (900) of an air vent, a driving means (100) connected to one of the wings and rotating the wings simultaneously to control the discharge direction of the wind when operating, and a power shaft (200) that engages with the driving means to transmit power.
