Disclosed is an air vent for an automobile that is structurally improved so that an outlet is slimed down. The air vent for an automobile includes a duct housing configured to guide a flow of air and having an outlet formed therein, a first wing and a second wing disposed to be spaced apart from each other inside the duct housing, a link configured to control a rotation of each of the first wing and the second wing, and a handle unit coupled to the link and configured to control a movement of the link, wherein the link is disposed to be movable and rotatable inside the first wing.

Disclosed is a vehicle air vent improved to simplify an operation mechanism by reducing the number of components for adjusting a wind direction while an outlet is slimmed. The vehicle air vent includes a vehicle air vent including a duct housing, a first wing assembly disposed at a side of an outlet of the duct housing, a second wing assembly disposed in the duct housing, and a knob coupled to the first wing assembly, wherein the knob includes a knob pin movably disposed in the first wing assembly.

An air vent assembly includes an air inlet, an air outlet, and a plurality of channels positioned between the air inlet and the air outlet. A first set of fixed vanes is positioned in a first one of the channels. The fixed vanes of the first set are angled or curved in a first direction with respect to a flow vector of the air inlet. A second set of fixed vanes is positioned in a second one of the channels. The fixed vanes of the second set are angled or curved in a second direction with respect to a flow vector of the air inlet. A gate is positioned within grooves of each of the first and second sets of fixed vanes. The gate is configured to regulate a position at which air may enter the first and second channels from the air inlet.

A flap stopper for a rotatable flap for controlling an air flow may include a round bearing support disc, a round stopper support disc, stop elements, and connecting ribs. The stopper support disc may be spaced apart from the bearing support disc in an axial direction. The stop elements may be arranged on the stopper support disc. The connecting ribs may be arranged between the bearing support disc and the stopper support disc. The bearing support disc, the stopper support disc, the stop elements, and the connecting ribs may be formed as an integral plastic injection-molded part.

A ventilation system for a vehicle includes a duct with an outlet. A housing is in fluid communication with the outlet. A vane is disposed within the housing. The vane has a first pivot axis and a second pivot axis. A first electric motor is configured to pivot the vane relative to the first pivot axis, and a second electric motor is configured to pivot the vane relative to the second pivot axis. A controller is configured to control the first electric motor to pivot the vane relative to the first pivot axis and to control the second electric motor to pivot the vane relative to the second pivot axis.

A rotary apparatus includes a motor, a plurality of gears including an output gear, and a housing accommodating the plurality of gears and the motor. The housing includes a first surface portion, a second surface portion facing the first surface portion and spaced apart from the first surface portion, and a sidewall portion provided at an outer peripheral portion of the first surface portion and the second surface portion and supporting the first surface portion and the second surface portion. One of the first surface portion and the second surface portion includes a vibration damping part opposing the output gear.

A vane adjustment device for an air register having a front vane and a rear vane is disclosed. The vane adjustment device comprises a rear vane connector rotatably connected to the rear vane about a first axis, an intermediate connector rotatably connected to the rear vane connector about a second axis different with the first axis, and a front vane connector rotatably connected to the front vane, the front vane connector including a sliding portion slidably and rotatably connected to the intermediate connector.

A method for driving an actuator of an HVAC system having a region of mechanical play is provided, and which comprises the steps of: a] monitoring a position of a movable member of the HVAC system or at least one rotatable element of the actuator to determine when the region of mechanical play has been entered or exited; and b] ramping a drive power to the actuator between a zero-velocity drive power and a steady-state-velocity drive power during the region of mechanical play. The HVAC system implementing the above method is not only capable of reducing the noise produced by an HVAC system, but is also capable of reducing an over-powering of the actuator when there is a low load on the system.

A ventilator includes a first louver, second louvers, side walls, a first inclined member, and a convex part. The first inclined member is inclined so that an opening area widens from the upstream side to a downstream side. The first inclined member has a vertex of inclination in a cross-sectional view that is positioned at the upstream side. The convex part is arranged adjacent at the upstream side in the airflow direction to the vertex. In a maximum angle state in which the first louver is rotated so that an upstream end part of the first louver is closest to the first inclined member, the upstream end part is positioned further to the downstream side in the airflow direction than the vertex. The convex part projects further to an inside of the flow path than the vertex, and extends across the second louvers when seen along the airflow direction.

The present invention relates to an air vent for a vehicle, provided with a damper for opening or closing the air path of a duct housing with improved operation quality and convenience. The air vent for a vehicle comprises: a duct housing (20) having an air path inside, a vane member for adjusting air discharge direction, a damper (21) for opening or closing the air path and a cover fixing boss (22) formed in an outside surface; a dial knob (30) rotationally coupled to the duct housing (20) and having a knob coupling hole (31); a damper rotation member (40) coupled to a damper (21) rotation shaft and having a pinion gear (41); a knob connector (50) having protruded coupling members (51), of which one is fitted into the knob coupling hole (31); a damper connector (60) link-connected to the knob connector (50), provided with a rack gear (61) to be engaged with the pinion gear (41), and having a guide hole (62) placed by the cover fixing boss (22) of the duct housing (20); and a guide cover (70) having an insertion part (71) fitted with the cover fixing boss (22), and a finishing part (72) coupled to the cover fixing boss (22) by a coupling member (73).
