Air conditioning register

Abstract

A single motor adjusts two different airflow directions. [Solution] The air conditioning register 10 comprises a first airflow direction adjusting member 31, a second airflow direction adjusting member 41, a motor 46, and a clutch device 51. The first airflow direction adjusting member 31 and the second airflow direction adjusting member 41 adjust the direction of the airflow of the conditioned air A1 by rotating about axes L1 and L2 located on the same line, thereby adjusting the airflow direction of the conditioned air A1 blown out from the outlet 22. When the output shaft of the motor 46 is rotated in the first rotational direction, the clutch device 51 transmits the rotational force to the first airflow direction adjusting member 31 and the second airflow direction adjusting member 41 to rotate. When the output shaft of the clutch device 51 is rotated in the second rotational direction opposite to the first rotational direction, the clutch device 51 transmits the rotational force to only one of the first airflow direction adjusting member 31 and the second airflow direction adjusting member 41 to rotate.

Claims

1. A retainer having a passage for air conditioning air, and the passage having an outlet at the downstream end in the direction of the air conditioning air flow, A first airflow adjustment member is disposed within the retainer and rotates about its own axis extending in an axial direction intersecting the flow direction, thereby adjusting the airflow direction of the conditioned air blown out from the outlet in direction A. A second airflow adjustment member is positioned within the retainer with its own axis aligned with the axis of the first airflow adjustment member, and rotates about the axis to adjust the airflow direction of the air conditioning air in direction B which intersects direction A. A motor that rotates the first wind direction adjusting member and the second wind direction adjusting member, A clutch device is provided between both the first wind direction adjusting member and the second wind direction adjusting member and the motor. An air conditioning register comprising the following: the clutch device transmits the rotational force in the first rotational direction to the first airflow adjustment member and the second airflow adjustment member when the output shaft of the motor is rotated in the first rotational direction, and transmits the rotational force in the second rotational direction to only one of the first airflow adjustment member and the second airflow adjustment member when the output shaft is rotated in the second rotational direction opposite to the first rotational direction, thereby causing it to rotate.

2. The clutch device comprises an annular outer member having an internal gear, an inner member arranged coaxially with the outer member in the region surrounded by the internal gear, having a recess on its outer circumference, and to which the output shaft of the motor is connected, and a planetary gear arranged in the recess and meshing with the internal gear and rolling. Of the outer circumferential surface of the inner member, a cut portion is formed at a location adjacent to the recess on the rear side in the first rotational direction, and an edge portion is formed at the boundary between the cut portion and the recess. One of the first wind direction adjusting member and the second wind direction adjusting member is connected to the outer member, and the other is connected to the inner member. The air conditioning register according to claim 1, wherein in the clutch device, when the inner member is rotated in the first rotational direction by the motor, some teeth of the planetary gear that rotates in conjunction with the rotation engage with the edge portion, causing the outer member to rotate together with the inner member, and when the inner member is rotated in the second rotational direction by the motor, the engagement of the planetary gear is released, so that the rotation of the inner member is performed while the rotation of the outer member is stopped.

3. The inner member has an elongated hole that extends in the circumferential direction of the inner member. The planetary gear comprises a gear body having teeth on its outer circumference and a shaft portion extending along the axis of the gear body. The air conditioning register according to claim 2, wherein the shaft portion is inserted into the elongated hole so as to be movable in the circumferential direction.

4. The first wind direction adjusting member comprises a first shaft that rotates about the axis of the first wind direction adjusting member, and a first fin having a fin component that protrudes more from a part of the outer surface of the first shaft than other parts, in a state inclined with respect to a virtual plane perpendicular to the axis of the first wind direction adjusting member. When the direction in which the first airflow adjustment member and the second airflow adjustment member and the outlet are arranged is defined as the alignment direction, and the direction perpendicular to both the axial direction and the alignment direction is defined as the orthoaxial direction, The aforementioned ventilation passage has a first passage section and a second passage section located on both sides of the first axis in the direction perpendicular to the axis, The air conditioning register according to claim 2, wherein at least a portion of the first airflow adjustment member in the circumferential direction of the first axis that is not provided with the fin component is configured to be located in the first passage and the second passage when the fin component is located on the upstream or downstream side of the first axis in the alignment direction.

5. When the fin component is designated as the first fin component, The first fin has a second fin component that protrudes from the outer circumferential surface of the first shaft, on the side of the first wind direction adjusting member opposite to the first fin component, straddling the axis. The air conditioning register according to claim 4, wherein the inclination direction of the second fin component with respect to the virtual plane is the same as the inclination direction of the first fin component with respect to the virtual plane.

6. The air conditioning register according to claim 4, wherein the second airflow direction adjusting member comprises a pair of second fins that extend along the axis of the second airflow direction adjusting member and sandwich the first fin from the outside in the radial direction of the first axis.

7. The second wind direction adjusting member includes a cylindrical portion into which the outer member is inserted so as to be integrally rotatable, The pair of second fins are integrally formed with the cylindrical portion, as described in claim 6 for an air conditioning register.
