Description

  The present invention relates to a vehicle air-conditioning blowout device, and more particularly, to a vehicle air-conditioning blowout device capable of adjusting a blowing direction of blown air-conditioning air.

Conventionally, for example, a technique described in Patent Document 1 is already known as this type of vehicle air-conditioning blow-out device. In this technique, a technique relating to an air-conditioning outlet structure having a bezel that can be moved in and out of an opening hole formed in the surface of an instrument panel and that is rotatable is disclosed. The bezel is provided with a plurality of horizontal fins, and the wind direction in the vertical direction is adjusted by rotating the horizontal fins. Also, the left and right wind direction adjustment is performed by rotating the bezel.

  However, in the above-described vehicle air-conditioning blow-out device, the air-conditioning air blown from the bezel outlet is blown out while being diffused in the direction of spreading in the left-right direction. Therefore, for example, in the summer, when the occupant wants to bathe the cold air blown out from the bezel locally (when the occupant wants to bathe in a concentrated manner), the occupant has to approach the outlet of the bezel.

  The present invention is intended to solve such problems, and an object thereof is to provide a vehicle air-conditioning blowout device capable of diffusing or converging air-conditioning air blown from a bezel outlet in the left-right direction. It is.

The present invention is for achieving the above object, and is configured as follows.
The invention according to claim 1 is provided in an opening hole formed in an instrument panel of a vehicle, and a blow-out opening is formed in a part of a side surface, and the shaft can be projected and retracted in the axial direction of the opening hole. An air-conditioning blowout device having a bezel that can rotate around a core,
An air-conditioning blowout device provided with a pair of vertical fins for rectifying the left-right direction of the air blown from the blowout port at the blowout port.
Thereby, the air-conditioning air blown from the outlet of the bezel can be diffused or converged in the left-right direction.

The best embodiment for carrying out the present invention will be described with reference to FIGS. In the following description, each direction of “front and rear, left and right, up and down” is each direction of “front and rear, right and left, up and down in the perspective view of FIG. 1”. FIG. 1 is a perspective view of the vehicle air conditioning blowing device according to an embodiment of the present invention in use. FIG. 2 is a perspective view showing a non-use state of the vehicle air-conditioning blow-out device of FIG. FIG. 3 is an exploded perspective view of the vehicle air-conditioning outlet device of FIG. 4A and 4B are views showing a state where the air passage in the use state of FIG. 1 is widened. FIG. 4A is a plan view thereof, and FIG. 5 is a view showing a state where the air passage in FIG. 4 is narrowed, (A) is a plan view thereof, and (B) is a sectional view taken along the line AA.

  In FIG. 1, reference numeral 10 denotes an instrument panel which is an interior part in a vehicle. An opening hole 11 is formed in the upper surface of the instrument panel 10, and a substantially L-shaped duct 20 is disposed in the opening hole 11. An air conditioner (not shown) is connected to one end of the duct 20 (horizontal opening end in FIG. 1). Further, a cylindrical bezel 40 is disposed at the other end (vertical opening end in FIG. 1) so as to be able to appear and retract in the vertical direction.

  Then, with reference to FIG. 3, the structure of the air-conditioning blowing apparatus mainly comprised from this duct 20 and the bezel 40 is demonstrated. A concave hole 20 a is formed at the axial center of the opening in the vertical direction of the duct 20 on the bottom surface of the duct 20. The lower end portion of the shaft 21 inserted from the opening in the vertical direction of the duct 20 is fitted into the concave hole 20a. Thereby, the shaft 21 is fastened so as to be integrated with the duct 20.

  The shaft 21 is fitted into a cylindrical guide 30 from above. Since this insertion has an appropriate frictional force, the guide 30 can be supported (positioned and fixed) at an arbitrary height with respect to the shaft 21. Further, the guide 30 can be rotated in an arbitrary rotation direction with respect to the shaft 21 by this insertion. Four guide legs 31 are formed on the side surface of the guide 30 so as to be inclined downward in the front-rear direction and the substantially left-right direction. Among these guide legs 31, the front and rear direction guide legs 31 are formed with projecting claws 31a at the tip portions thereof. Further, a cylindrical receiving portion 31b is formed at the distal end portion of the guide leg 31 in the substantially left-right direction.

  An upper wall 45 is formed on the cylindrical bezel 40, and an air outlet 41 is opened on the front side of the side surface of the bezel 40. A guide hole 42 that penetrates the upper end of the guide 30 is formed in the center of the upper wall 45. A locking hole 44 capable of locking the protrusion claw 31 a of the guide leg 31 is formed at the lower side of the front and rear sides of the side surface of the bezel 40. Thus, the guide 30 is assembled inside the bezel 40 with the upper end of the guide 30 penetrating through the guide hole 42 of the upper wall 45 of the bezel 40.

  Further, a round bearing hole 43 is formed at an end portion of the upper wall 45 of the bezel 40 in the substantially left-right direction. By inserting the vertical pivot shafts 51 and 52 of the vertical fin 50 into the round bearing hole 43 and the receiving portion 31 b of the guide leg 31, the vertical fin 50 is assembled so as to be rotatable with respect to the bezel 40. . As is clear from the enlarged view in FIG. 3, the upper support shaft 51 of the vertical fin 50 has a round shaft 51a at the lower portion and a square shaft 51b at the upper portion. Therefore, the vertical fin 50 can be rotated by fitting the round shaft 51 a into the round bearing hole 43 of the upper wall 45 in the upper support shaft 51 of the vertical fin 50. The vertical fin 50 is provided with a total of two pairs of left and right. Thereby, the direction of the left-right direction of the air-conditioning air which blows off from the blower outlet 41 can be rectified.

  Further, the two vertical fins 50 are coupled by a link member so as to rotate in synchronization. The link member will be described in detail. The link member slides on a rod arm 52 having a square bearing hole 52a at one end and a round shaft 52b projecting at the other end, and the round shaft 52b of the rod arm 52. A long hole 53a that can be fitted is formed by a rod bar 53 that is formed on both sides. Thereby, when one vertical fin 50 is rotated, the other vertical fin 50 is also rotated synchronously. In the center of the rod bar 53, a through hole 53 into which a rod 81 of a knob 80 described later can be inserted is formed.

  In this manner, the cap 70 is fitted into the upper end portion of the bezel 40 with the link member assembled to the upper pivot shaft 51 of the vertical fin 50. The cap 70 has two long holes 72 formed in parallel in the front-rear direction. Further, a long hole 71 different from the long hole 72 is formed in parallel behind the long holes 72. A knob 80 is assembled on the upper surface of the cap 70. This assembly will be described in detail. Locking legs 82 are suspended from the four corners of the lower surface of the knob 80, and claws are formed outwardly at the lower ends of the locking legs 82. As a result, the locking leg 82 of the knob 80 is fitted into the elongated hole 72 of the cap 70, so that the knob 80 can be moved in the front-rear direction while being assembled to the cap 70. A rod 81 is suspended from the lower surface of the knob 80, and the rod 81 is fitted in the through hole 53 b of the rod bar 53 while penetrating the long hole 71 of the cap 70.

  A plurality of arc-shaped horizontal fins 60 are arranged at predetermined intervals in the air outlet 41 of the bezel 40 along the outer periphery of the bezel 40. Each of these horizontal fins 60 is attached so as to cover the air outlet 41 via a fin support 61 attached to both ends thereof. These horizontal fins 60 are coupled so as to rotate in synchronization with each other via a well-known link member (not shown).

  Next, the operation of the air-conditioning blowout apparatus having the above-described configuration will be described. First, the bezel 40 is lifted upward from the state shown in FIG. 2 to the state shown in FIG. Further, the direction of the bezel 40 is rotated as necessary. Thereafter, when the air-conditioning equipment is operated, air-conditioned air is blown out from the outlet 41 of the bezel 40. FIG. 4 shows a state in which the air passage is widened, and the vertical fin 50 is rotated in a direction in which the air-conditioning air blown from the air outlet 41 of the bezel 40 is diffused in the left-right direction. When the knob 80 is moved rearward (leftward in FIG. 4) from this state, the rod bar 53 is moved rearward (leftward in FIG. 4). As a result, the rod arm 52 is tilted, and the vertical fin 50 is rotated in accordance with the tilt (see FIG. 5). When the knob 80 is moved in the reverse direction, the vertical fin 50 is returned to the state before the rotation.

  Thus, by moving the knob 80, the pair of vertical fins 50 can be easily rotated in a synchronized state. Thereby, the air-conditioning air which blows off from the blower outlet 41 of the bezel 40 can be spread | diffused or converged in the left-right direction.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In the embodiment, the bezel 40 is described as an example in which the bezel 40 is lifted manually. However, the present invention is not limited to this, and the bezel 40 may be configured to be lifted electrically using an actuator or the like.

FIG. 1 is a perspective view of the vehicle air conditioning blowing device according to an embodiment of the present invention in use. FIG. 2 is a perspective view showing a non-use state of the vehicle air-conditioning blow-out device of FIG. FIG. 3 is an exploded perspective view of the vehicle air-conditioning outlet device of FIG. 4A and 4B are views showing a state where the air passage in the use state of FIG. 1 is widened. FIG. 4A is a plan view thereof, and FIG. 5 is a view showing a state where the air passage in FIG. 4 is narrowed, (A) is a plan view thereof, and (B) is a sectional view taken along the line AA.
