Description

Regulating device of air outlet {REGULATOR FOR AIR BLOWING PORT}

The present invention relates to an apparatus for adjusting an air discharge port having a plurality of wing plates integral with the shaft portion supported by the bearing hole and connected to each other by an interlocking member.

A louver for adjusting the wind direction is provided at the discharge port for discharging air into the vehicle interior of the vehicle. The louver is generally linked to a plurality of wing plates by an interlocking member such as a link mechanism or a cam mechanism. The louver is rotated by a manual operation member such as a dial exposing a part of it on the surface of the instrument panel panel. It is possible to collectively change the directions of a plurality of installed wing plates (see Japanese Patent Application Laid-Open No. 63-112210, etc.).

On the other hand, the wing plate constituting the louver is subjected to wind pressure directly, so if there is a tremor, it will vibrate and cause abnormal sound. In order to support the vane so that there is no tremor, it is necessary to closely fit the shaft portion integrally formed in the vane and the bearing hole formed in the frame.

However, in order to closely fit the shaft and the bearing hole, a high manufacturing precision and an assembly precision are required, which makes the manufacturing process complicated. In addition, the wing plate and the frame supporting the wing plate are generally injection-molded with a thermoplastic synthetic resin material, but the wing plate and the frame body may be thermally deformed due to changes in temperature or strength of air-conditioning and heating. The operating force of the plate may change greatly.

The present invention has been made to solve such inconvenience of the prior art, the main object of which is that the operation is more smooth and smooth without the effect of temperature changes without causing the manufacturing process complicated. It is to provide an apparatus for adjusting an air discharge port that can be improved to suppress generation.

Embodiment of the Invention

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows the periphery of the instrument panel panel of the automobile to which the present invention is applied. The air discharge port A is provided in the left and right edge part and center part of this instrument panel panel P. As shown in FIG. Each of these air discharge ports A is connected to an air duct provided in the instrument panel panel P, and discharges the air passing through the air conditioner delivered by the blower into the cabin.

As shown in FIG. 2, the air discharge port A is formed in the case 2 and the front side of the case 2 which form a substantially rectangular tube shape in which the flange 1 was formed in the connection surface with respect to the indoor side surface of the instrument panel panel P. As shown in FIG. Intermittent inflow of air from a plurality of horizontal wing plates 3 freely inclined movement and a plurality of vertical wing plates 4 freely inclined movement inward in the case 2 and air ducts (not shown) The damper 5 (refer FIG. 3) which consists of a butterfly valve for this is provided.

The horizontal wing plate 3 rotates the side dial 6 provided at the left end of the flange 1 in FIG. 2 to incline and move around the horizontal axis to change the wind direction in the vertical direction. Is a tilting movement around the vertical axis by rotating the lower dial 7 provided at the lower end of the flange 1 in Fig. 2 to change the wind direction in the left and right directions.

The side dial 6 is freely rotatable on the side wall of the case 2, and a part of its outer circumferential surface slightly protrudes from the front of the flange 1, and the exposed portion of the front of the flange 1 is fingertip. It is possible to operate by rotating. The lower dial 7 is freely pivoted on the bottom wall of the case 2, and similarly to the side dial 6, a part of its outer circumferential surface slightly protrudes from the front surface of the flange 1, and this flange 1 The exposed part on the front of the) can be rotated with the fingertips.

On the outer side surface of the side dial 6, as shown in FIG.3, FIG.4, the pinion 8 coaxially with a rotation center axis | shaft is provided integrally. The pinion 8 is engaged with the sector gear 9.

The sector gear 9 is pivotally freely pivoted at a forward (engine side) lower position obliquely with respect to the rotation center of the side dial 6 on the side wall of the case 2, and the rocker arm is moved from the rotation center toward the engine side. (10) is extended. The free end of the rocker arm 10 forms a part of an arc around the pivot axis of the rocker arm 10, and one end thereof is bent outward in the radial direction to form an approximately L-shaped long hole 11. The free end of the lever member 12, which is integrally provided with the pivot central axis of the damper 5, is connected to this long hole 11.

When the side dial 6 is rotated downwardly (in the arrow direction) while the damper 5 shown in FIG. 3 is closed, the rocker arm 10 is left by engagement of the pinion 8 and the sector gear 9. Rotate to Then, the pin 12a firmly installed at the free end of the lever member 12 is press-fitted into the radially outer portion 11a of one end of the long hole 11 formed at the free end of the rocker arm 10, and the damper 5 is pressed in. Is driven in the open direction. Since the rotation radius of the lever member 12 is smaller than the radius of curvature of the long hole 11, when the damper 5 reaches the fully open position shown in FIG. 4, the long hole 11 of the free end of the rocker arm 10 is reached. ) The pin 12a of the free end of the lever member 12 is fitted to the arcuate portion. Therefore, the damper 5 stops at the fully open position, but can further continue the downward rotation operation of the side dial 6 by the range of the long hole 11.

The plurality of horizontal vane plates 3 (for example, 5 sheets) have a horizontal axis between the left and right sidewall inner surfaces of the case 2, and both ends thereof are stacked. 5 and 6, the support shaft 13 of each horizontal wing plate 3 is located at the rear upper edge side of the horizontal wing plate 3 in the closed state (see FIG. 5), and is open ( It is formed at a position adjacent to the upper side of the front edge of the horizontal wing plate (see FIG. 6), and as shown in FIG. 5, each closed horizontally along the surface of the flange 1 drawing a gentle arc when closed. The wing plates 3 are lined up without a gap, and as shown in Fig. 6, the horizontal wing plates 3 are arranged so as to extend in parallel with an appropriate gap at the time of opening.

An arm 14 protrudes from the rear surface of each horizontal wing plate 3. This arm 14 is located in the lower edge side of the rear surface of the horizontal wing plate 3 in the closed state, and is provided in the position adjacent to the upper side of the rear edge of the horizontal wing plate 3 in the open state. That is, the support shaft 13 and the arm 14 are provided in the position which is substantially symmetrical with respect to the centerline along the longitudinal direction of the horizontal wing plate 3.

Each free end of the arm 14 is connected to each other by an interlocking member 15 forming a comb shape. These arms 14 and the interlocking member 15 are connected so that relative rotation is possible, and by moving the interlocking member 15 up and down, all the horizontal wing plates 3 interlock and incline and move simultaneously.

The projection 16 protrudes toward the engine side in the vertical direction of the interlocking member 15. The projection 16 is formed with a long hole 17 substantially in the front-rear direction.

The long hole 17 is indented with a pin 18 protruding from the inner side of the side dial 6. The pin 18 penetrates the long hole 19 formed in the side wall of the case 2 so as to form an arc around the rotational axis of the side dial 6, thereby defining its movable range.

In the state in which the damper 5 is closed, each horizontal wing plate 3 is also in the closed state, as shown in FIG. When the side dial 6 is rotated downward in this state, the interlocking member 15 moves upward with the pin 18 integral with the side dial 6, and each horizontal wing plate 3 connected thereto. This simultaneously shifts in the open direction. At the same time, the damper 5 is opened as described above. And even after the damper 5 is fully opened, as shown in FIG. 6, within the range defined by the arc-shaped long hole 19 formed in the side wall of the case 2, each horizontal wing plate 3 is furthermore. Continue tilting in the open direction. At this time, it is possible to adjust the wind direction in the vertical direction in accordance with the inclined movement angle of each horizontal vane (3).

On the other hand, the plurality of (for example, five) vertical wing plate 4 has a support shaft (20a, 20b) protruding to each of the upper and lower ends of the case (2) so as to be inclined in the horizontal direction about the vertical axis. It is supported by the ceiling wall 2R and the bottom wall 2B.

The pin 21 is vertically formed in the lower edge of the one vertical wing plate 4 located in the center among the plurality of vertical wing plates 4 at an offset position in front of the support shaft 20b. As shown in FIG. 7, the pin 21 penetrates the long hole 22 formed in the bottom wall 2B of the case 2 so as to form an arc of concentricity with the center of rotation of the lower dial 7. The end is engaged with the long hole 23 along the substantially front-back direction formed in the lower dial 7. As shown in FIG. Moreover, the projection (not shown) is formed perpendicularly in the position corresponding to the pin 21 of the center vertical wing plate 4 in the other vertical wing plate 4, These projections and the pin 21 are common link plate ( 24, all the vertical wing plates 4 are interlocked with each other.

In this way, when the lower dial 7 is rotated left and right, all the vertical wing plates 4 move left and right simultaneously.

A rotational resistance imparting means 25 is provided at the attachment portion of the lower dial 7 to the bottom wall 2B of the case 2. As a result, an appropriate rotational resistance is applied to the vertical vane plate 4 so that the vertical vane plate 4 does not shake.

The rotational resistance imparting means 25 provided in the attachment part of the lower dial 7 to the bottom wall 2B of the case 2, as shown in FIG. 8, is a cylindrical part 41 integral with the lower dial 7. ) And a plurality of O-rings (two in this embodiment) mounted successively in the axial direction in the boss portion 42 protruding downward from the bottom wall 2B and the annular void RG formed in the fitting portion thereof. It consists of 43. In addition, the cylindrical part 41 is being fixed by the screw 44 attached to the center of the boss | hub part 42 by screwing.

On the other hand, these O-rings 43 are formed of a silicone resin material having self-lubrication, thereby reducing torque fluctuations caused by temperature changes. If the O-ring is used, the desired rotational resistance can be easily adjusted by setting the radial size of the annular cavity RG to which the O-ring is attached or decreased. It goes without saying that the rotational resistance imparting means 25 can also be applied to the support of the side dial 6.

The upper and lower support shafts 20a and 20b of the vertical wing plate 4 are attached to the support plates 26U and 26L attached to the ceiling wall 2R and the bottom wall 2B of the case 2, respectively, as shown in FIG. It is fitted in the formed bearing hole 27 (lower support plate 26L is omitted in illustration). These support plates 26U and 26L are formed of elastic material having abundant elasticity, but the support plates 26U and 26L are formed by a two-color molding method in which the support shafts 20a and 20b of the vertical wing plate 4 formed above are inserted. By doing so, it can contribute to the reduction of a manufacturing process.

Among these support plates 26U and 26L, in particular, the left and right ends of the upper support plate 26U attached to the ceiling wall 2R are formed with two branch portions 28 bent upward as shown in FIGS. 9 and 10. Only the distal end of the second branch 28 is brought into contact with the lower surface of the ceiling wall 2R with an elastic force in the vertical direction. This structure contributes to improving the supporting stability of the front and back sides of the upper support plate 26U.

The upwardly convex part 29 is formed in the center of the left-right direction of 26 U of upper support plates. The convex portion 29 is engaged with the front and rear concave grooves 30 formed on the lower surface of the ceiling wall 2R, whereby positioning in the left and right directions of the upper support plate 26U is achieved. In the upper support plate 26U, the convex portion 29 abuts on the front end of the concave groove 30, and the protrusions 32 formed on the upper surface of the upper support plate 26U are formed in the ceiling wall 2R. Positioning in the front-rear direction is made by being fitted to.

According to this, the right and left both ends of the upper support plate 26U are brought into contact with the lower surface of the ceiling wall 2R with a resilient force, and a suitable initial clearance between the lower surface of the ceiling wall 2R and the upper surface of the upper support plate 26U. Since G is open, even if the case 2 is deformed due to a temperature change or the like, the amount of deformation is absorbed in the gap G, and the axial force acting on the vertical wing plate 4 is not changed. Thereby, it can suppress that the rotational torque of the vertical vane board 4 fluctuates due to the deformation | transformation of the case 2 by temperature change.

Although the above embodiment has described an application example to the air discharge port toward the interior of a vehicle, the present invention is not limited to the above, but can be applied to the discharge port of a home air conditioner, for example.

As described above, according to the present invention, since a resilient portion that is deformable with respect to the axial direction of the wing plate is formed on the support plate for attaching the plurality of wing plates to the air discharge port (claim 1), the thermal deformation between the air discharge port and the wing plate is determined by the support plate. Since it is absorbed by the elastic deformation, it can exhibit a great effect in keeping the rotational torque of the vertical wing plate stable at all times.

In particular, when the elastic portions are formed at both ends of the support plate (claim 2) or the elastic portions are formed in the shape of two branches (claim 3), the attachment stability of the support plate to the air discharge port can be further improved.

In addition, when the O-ring made of a silicone resin material having self-lubrication is fitted to the support shaft of the rotation control section for imparting displacement to the interlocking member to the interlocking member (claim 4), the rotation control section is caused by temperature change. It is possible to further reduce the torque fluctuation.
