Description

  The present invention relates to an air outlet device for a vehicle.

(I) Patent Document 1 discloses a barrel-type air outlet device in which a barrel (wind direction regulating member) is rotatable with respect to a housing.
Further, (ii) Patent Document 2 discloses a fin-type air outlet device in which a plurality of fins can be rotated around respective axis centers.

However, the air outlet devices (i) and (ii) have the following problems.
(I) Since it is a barrel type (as the whole barrel 18 rotates with respect to the housing 12 as shown in FIG. 5 of Patent Document 1), the barrel protrudes from the housing in the apparatus depth direction when the barrel rotates. Therefore, the depth dimension of the apparatus becomes relatively large, and it is difficult to reduce the depth dimension of the apparatus.
(Ii) Since the fin type is used instead of the barrel type, the depth dimension of the apparatus can be reduced as compared with the barrel type. However, as shown in FIG. 1 of Patent Document 2, the actuator 6 not only moves the operating shaft 21 in the A direction, but also rotates the cylindrical portion 24 in the B direction. There is a need for large actuators. Therefore, there is a limit in reducing the depth dimension of the apparatus. In addition, the actuator 6 is disposed on the back side of the device of the fins 10, 11, 12 and the ring 3, and there is a limit to reducing the depth dimension of the device also in this respect.
Therefore, it is difficult to provide the air outlet device of (i) and (ii) above on the passenger compartment ceiling, which is restricted in the height direction due to design or the like.

The vehicle interior ceiling R is not only a substantially flat flat portion R1 vertically above the seat S, but also a step portion R2 provided in the vehicle front-rear direction intermediate portion of the flat portion R1, and shoulders of both ends of the flat portion R1 in the vehicle left-right direction. Part R3 is also included.
The device 10 is provided to send wind to the occupant seated in the rear seat (rear seat) S1 of the vehicle. However, the device 10 may be provided to send wind to the occupant seated in the front seat (front seat) S2 of the vehicle.

  The apparatus 10 includes a panel 20 and a housing 30 as shown in FIG. 1, and includes a fin 40 and a connecting member 50 as shown in FIG. 6, and a drive source (actuator) as shown in FIG. 1. , Motor) 60 and a transmission mechanism 70.

The panel 20 is fixedly attached to the passenger compartment ceiling R. The panel 20 has a thin plate shape. The panel 20 may have a one-part configuration as shown in FIGS. 11 and 12, or may have a multiple-part (two-part) configuration as shown in FIGS.
As shown in FIG. 3, the panel 20 rises from the circular hole 21, the annular flat plate-like shelf 22 provided at the peripheral edge of the circular hole 21, and the counter vehicle compartment side from the radial intermediate portion of the shelf 22. An annular rising wall 23 and a retaining claw 24 are provided as shown in FIG.

As shown in FIG. 3, the circular hole 21 is a through hole that penetrates the panel 20 in the thickness direction of the panel 20.
As shown in FIG. 1, the rising wall 23 inhibits the movement of the transmission mechanism 70 by preventing the rising wall 23 and the transmission mechanism 70 from interfering (contacting) with each other in the circumferential direction of the rising wall 23. In order to suppress this, a notch 23a is provided.
As shown in FIG. 7, the retaining claws 24 are provided to prevent the housing 30 from being detached from the panel 20 when the housing 30 moves (rattles) relative to the panel 20 toward the opposite side of the vehicle compartment. It is done. The retaining claws 24 are provided on the rising wall 23. Although at least one retaining claw 24 may be provided, FIG. 6 shows a case where three retaining claws 24 are provided in the circumferential direction.

As shown in FIG. 1, the housing 30 has a ring shape. The housing 30 is disposed at the peripheral edge of the circular hole 21 of the panel 20 and is rotatably supported by the panel 20. The center (rotation axis) P of the housing 30 always coincides with (including substantially coincides with) the center of the circular hole 21. As shown in FIG. 3, the housing 30 is disposed on the inner side in the radial direction of the rising wall 23 on the side surface of the shelf 20 of the panel 20 opposite to the vehicle compartment.
The inner side in the radial direction of the housing 30 and the circular hole 21 of the panel 20 serve as a blow-out port for blowing air that has flowed through an unillustrated duct in the vehicle into the vehicle interior.

As shown in FIGS. 6 and 7, a plurality of fins 40 are provided, for example, a four-plate configuration. However, the number of fins 40 is not limited to four, but may be two, three, or five or more.
Each fin 40 of the plurality of fins 40 is attached to the housing 30 so as to be rotatable around the respective axis Q. The axis Q of each fin 40 is orthogonal to the axis P of the housing 30. As shown in FIG. 7, the plurality of fins 40 include a closed position 40 a that closes the radially inner side of the housing 30, a rotation between the closed position 40 a 90 degrees or approximately 90 degrees, and between adjacent fins 40 and between the housing 30 and the fin 40. Between the housing 30 and the open position 40b that allows air to pass therethrough.

  The connecting member 50 is formed of a resin rod-like member (link bar) and is connected to a position other than the axis Q of each fin of the plurality of fins 40 so as to be relatively rotatable. Therefore, when any one of the plurality of fins 40 is rotated around the axis Q with respect to the housing 30 by hand, all of the plurality of fins 40 are interlocked with each other while maintaining a parallel state with respect to the housing 30. It rotates around each axis Q.

  The drive source 60 is fixedly attached to the panel 20 as shown in FIG. The drive source 60 is disposed on the outer side (outer peripheral side) in the radial direction of the housing 30.

  The transmission mechanism 70 is a mechanism that does not transmit the force of the drive source 60 to the fins 40 and the connecting member 50 but transmits only the housing 30. The transmission mechanism 70 includes a pulley 71 and a housing rotation mechanism 72.

  The pulley 71 is fixed to the output shaft of the drive source 60, and is rotated around the pulley axis P1 by the drive source 60. The pulley shaft core P <b> 1 is parallel to the shaft core P of the housing 30. The pulley 71 is disposed on the outer side (outer peripheral side) in the radial direction of the housing 30.

The housing rotation mechanism 72 is a mechanism that transmits the rotation of the pulley 71 to the housing 30 when the pulley 71 rotates around the pulley axis P1 and rotates the housing 30 around the axis P with respect to the panel 20.
The housing rotation mechanism 72 includes a belt 72 a wound around the pulley 71 and the housing 30, and a roller 72 b that increases the winding angle of the belt 72 a around the pulley 71 and the housing 30.
The belt 72a is made of a flexible material that does not expand or contract and is negligible even if it expands and contracts.
The roller 72b is attached to the panel 20. The roller 72b may be rotatably attached to the panel 20, or may be fixedly attached to be non-rotatable. The roller 72b prevents the pulley 71 from moving toward the housing 30 due to the force applied to the pulley 71 from the belt 72a by allowing the belt 72a to wrap around the entire circumference of the pulley 71 and the housing 30. The force applied to the housing 30 from the belt 72a prevents the housing 30 from moving toward the pulley 71 side.

Next, an operation common to the first and second embodiments of the present invention will be described.
In the embodiment of the present invention, the housing 30 is rotatable about the axis P with respect to the panel 20, and the plurality of fins 40 are rotatable about the axis Q with respect to the housing 30. The air blowing direction of the device 10 can be changed three-dimensionally.

In the embodiment of the present invention, the following effects can be obtained.
(A) Since the housing 30 includes a plurality of fins 40 that are rotatably mounted around the respective axis Q, the apparatus 10 is not a barrel type but a fin type. Therefore, the depth dimension of the device 10 can be reduced as compared with the case where the device 10 is a barrel type (in the case of the conventional (i)).
(B) Since the force of the drive source 60 is transmitted to the housing 30 without being transmitted to the fins 40 and the connecting member 50 by the transmission mechanism 70, the drive source 60 need only have one movement. Therefore, the drive source 60 can be reduced in size and the depth dimension of the device 10 can be reduced as compared with the case where the drive source 60 is moved two or more times (conventional case (ii)).
(C) Since the drive source 60 is disposed outside the housing 30 in the radial direction, the apparatus is more in comparison with the case where the drive source 60 is disposed on the back side (opposite vehicle compartment side) of the housing 30 (conventional (ii)). 10 depth dimensions can be reduced.
In order to satisfy all of the above (a) to (c) at the same time, the depth dimension of the device 10 is such a size that the device 10 can be installed on the ceiling R of the passenger compartment, thereby affecting the appearance of the vehicle and the feeling of pressure in the passenger compartment. The apparatus 10 can be installed in the passenger compartment ceiling R without being accompanied.

  Since the housing rotation mechanism 72 of the transmission mechanism 70 includes the belt 72a wound around the pulley 71 and the housing 30, even if the pulley 71 is disposed on the outer side in the radial direction of the housing 30, the belt 72a causes the pulley 71 to move. The rotation can be transmitted to the housing 30 to rotate the housing 30. Therefore, the pulley 71 can be arranged on the outer side in the radial direction of the housing 30, and the depth dimension of the device 10 can be reduced as compared with the case where the pulley 71 is arranged on the rear side of the housing 30 (on the side opposite to the passenger compartment).

In the above-described embodiment of the present invention, the case where the housing rotation mechanism 72 of the transmission mechanism 70 is a mechanism including the belt 72a has been described. However, the housing rotation mechanism 72 of the transmission mechanism 70 has an outer periphery of the pulley 71 as shown in FIG. The mechanism may include a pulley-side gear 72c provided on the surface and a housing-side gear 72d provided on the outer peripheral surface of the housing 30.
When the housing rotation mechanism 72 is a mechanism including a pulley-side gear 72c and a housing-side gear 72d, the pulley-side gear 72c, the housing-side gear 72d, and the housing-side gear 72d are arranged even when the pulley 71 is disposed radially outside the housing 30. Can be engaged directly or via at least one gear (not shown) to transmit the rotation of the pulley 71 to the housing 30 to rotate the housing 30. Therefore, the pulley 71 can be arranged on the outer side in the radial direction of the housing 30, and the depth dimension of the device 10 can be reduced as compared with the case where the pulley 71 is arranged on the rear side of the housing 30 (on the side opposite to the passenger compartment).
