2. In claim 1, the dam is further provided with a soft material adhesion member on the outside by double injection molding, and An air vent with a V-dam applied, characterized in that the above-mentioned contact member is provided with a groove corresponding to the wing.
3. An air vent with a V-dam applied, wherein, in claim 1 or 2, the dam is characterized by having a recessed portion on one side of the connecting portion of a longitudinal member and cut holes on both sides.
4. An air vent with a V-dam applied, characterized in that, in claim 1, the horizontal member and the vertical member are integrally assembled and joined by pressure through an assembly structure of a support groove, a support projection, and a fixing hook.

Description

An air vent with a V-dam The present invention relates to an air vent to which a V-dam is applied to improve structural rigidity while increasing airtightness performance by attaching an air vent configured to attach a wing to a V-dam after being manufactured separately in a casing having a reinforcing structure. Generally, vehicles are equipped with an air conditioning system that regulates the interior temperature according to the season, and the cold or warm air generated by this system is introduced through ducts into an outlet installed on the vehicle's interior instrument panel and then discharged into the vehicle's interior. Here, the discharge port is equipped with an air vent that controls the direction and volume of cold or warm air generated from the air conditioning system. In addition, the air vent is equipped with a horizontal wing and a vertical wing to control the direction of cold and warm air entering the vehicle's interior in the up-down and left-right directions, and a wing knob is provided to rotate the horizontal wing and the vertical wing in the up-down and left-right directions, respectively. In relation to such technology, the technology of an air vent is disclosed in the prior art patent No. 2023-36464, and as shown in FIG. 1, the air vent device (100) of a vehicle includes a duct housing (110), a front wing (120), and a spacer (130). And, the above duct housing (110) forms the exterior of the air vent device (100), and when the front wing (120) closes the vent hole of the duct housing (110), the gap difference between the wings is reduced by wind pressure and prevents air leakage. Additionally, the spacer (130) includes a lower spacer (131) and an upper spacer (132) positioned between the duct housing (110) and the front wing (120) to prevent leakage into the vehicle's interior when the front wing (120) is overlapped. However, the above air vent device has the disadvantage that deformation of the housing occurs because it is structurally weak as the front wing (120) must maintain a shape in which it directly contacts the duct housing (110). In addition, there is a disadvantage that it becomes difficult to maintain airtightness between the duct housing (110) and the front wing (120) when the assembly position of the front wing (120) is deformed. FIG. 1 is a front view illustrating a conventional air vent. FIG. 2 is a perspective view illustrating an air vent according to the present invention. FIG. 3 is an exploded view of an air vent according to the present invention. FIG. 4 is a perspective view illustrating the assembled state of an air vent according to the present invention. FIG. 5 is a module assembly diagram of an air vent according to the present invention. FIGS. 6 and FIGS. 7 are a cross-sectional view of the assembled state and an exploded view, respectively, of an air vent module according to the present invention. FIG. 8 is a cross-sectional view illustrating a dam according to another embodiment of the present invention. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. As illustrated in FIGS. 2 to 8, the air vent (A) of the present invention has an air vent module (200) mounted in a through hole (110) formed in a frame (100) that is mounted on a dashboard or crush pad, etc. At this time, the through hole (110) is installed to supply warm air or cold air to an indoor space connected by a duct to an air conditioning system that forms cold air or warm air. And, a support ridge (130) is formed along the edge of the through hole (110) formed in the frame (100) to which the air vent module (200) is in close contact, and a deformation prevention rib (150) is provided on one side of the inner surface. In addition, the air vent module (200) is composed of a set of horizontal members (230) that are mounted so that each end of a plurality of wings (210) rotates, and a set of vertical members (250) connected to each end of the horizontal members (230) to assemble them together. At this time, the vertical member (250) is integrally provided with a dam (251) to which one side of the wing closing the Euro is respectively closely attached. In addition, the above dam (251) is installed with an overall V-shape so as to protrude to correspond to the rotation angle of the wing. And, the above dam (251) may further be provided with a connecting member (261) on the outside by double injection. In addition, the above-mentioned contact member (261) may be integrally provided with a groove (262) corresponding to the wing. In addition, the above dam (251) is provided with a recess (263) that is recessed on at least one side of the connecting part of the vertical member. At this time, the dam (251) may be provided with cut holes (265) on both sides. Furthermore, the above horizontal member (230) and vertical member (250) are configured such that the assembly structure of the support groove (281), the support projection (283),
