Description

The present invention relates to a ventilator installed in a motor vehicle.

For example, Japanese Patent Laid-Open No. 2019-31192 (Patent Document 1) and Japanese Patent No. 6454223 (Patent Document 2) describe ventilators that can adjust the direction of the air blown out.
For example, in the ventilator described in Patent Document 1, a fin assembly is attached to the air outlet of a panel so as to be rotatable up and down. The fin assembly includes a plurality of downstream horizontal fins arranged in parallel along the width direction, a plurality of upstream vertical fins arranged along the height direction on the upstream side of the horizontal fins, a link connecting the plurality of upstream vertical fins to each other, and an operation knob attached to one of the upstream vertical fins. The width direction and the height direction can also be referred to as the horizontal direction and the vertical direction.

In the ventilator disclosed in Patent Document 1, the direction of air blown from the ventilator can be adjusted in the height direction by rotating the fin assembly up and down. Furthermore, by operating the operation knob in the width direction, the upstream vertical fins can be rotated to adjust the direction of the air blown from the ventilator in the width direction.

The ventilator described in Patent Document 2 includes an air outlet provided with guide fins (movable fins) and a decoration device provided with immovably provided decorative fins. Further, the guide fin is supported by the decorative fin so as to be pivotable about a rotating shaft attached to the downstream end edge. In the ventilator of Patent Document 2, the wind direction can be adjusted in the height direction by rotating the guide fins up and down. It is also explained in DE 10 2009 2012 that the air outlet has the advantage that it can be well integrated into the interior of a motor vehicle, so that the transition from the decorative device to the air outlet is almost invisible.

JP 2019-31192 Publication Patent No. 6454223

For example, in Patent Document 1, the panel on which the ventilator is attached is formed with a design surface that corresponds to the downstream horizontal fins arranged in the width direction of the ventilator. This allows a sense of unity between the panel's design surface and the ventilator. However, when the fin assembly is rotated up and down to adjust the airflow direction, the position of the downstream horizontal fins shifts upward or downward relative to the panel's design surface. This destroys the sense of unity between the panel's design surface and the ventilator, leading to a deterioration in the appearance or external quality of the ventilator and its vicinity within the vehicle cabin.

On the other hand, in the ventilator of Patent Document 2, even if the guide fin is rotated up and down, when the ventilator is viewed from the air outlet side, the downstream end of the guide fin does not move and the position of the downstream end is maintained, so there is no loss of unity between the design surface and the ventilator as in Patent Document 1, for example, and it is possible to prevent a decrease in appearance or external quality.

However, for example, to improve the design of an automobile or to differentiate it from other automobiles, there may be a demand for a ventilator that not only maintains the position of the downstream end of the guide fin when the guide fin is rotated, but also has an improved appearance, such as making the downstream end of the guide fin appear not to rotate.

The present invention was made in consideration of the above-mentioned problems with the conventional technology, and its purpose is to provide a ventilator that can be relatively easily constructed so that the downstream end of the movable fin does not move even when the movable fin is rotated, and that can further improve the appearance.

In order to achieve the above-mentioned object, the ventilator provided by the present invention is a vehicle ventilator in which at least one movable fin for adjusting the direction of air is rotatably arranged at the opening of an air outlet, the ventilator comprising: a fin member having the movable fin; and at least one decorative member having a decorative fin, the fin member having a rotatably arranged movable fin main body portion and a fixed portion immovably arranged at the downstream end of the movable fin, the fixed portion being arranged along the rotation axis of the movable fin main body portion and having a shape that contacts or is close to the movable fin main body portion along the rotation axis, the outer surface of the fixed portion having the same shape or a similar shape to at least a portion of the outer surface of the tip of the decorative fin, the fin member having at least a pair of arm portions supporting the movable fin, the movable fin main body portion being rotatably connected to the pair of arm portions, and the fixed portion being fixed to the tip portions of the pair of arm portions .

It is also preferable that the ventilator of the present invention has a case member to which the fin member and the decorative member are attached.

The ventilator of the present invention can be relatively easily constructed so that the downstream end of the movable fin does not move even when the movable fin is rotated, and the appearance can be further improved by preventing the downstream end of the movable fin from rotating.

Such a ventilator 1 is also called a wind direction adjustment device or an air blowing device.

Here, with respect to the ventilator 1, the front-to-rear direction is the direction along the air blowing direction from the ventilator 1 when the movable fins 12 described below are held in a neutral position (center position). In this case, the downstream side of the air flow is the front, and the upstream side is the rear. The up-down direction and the left-right direction are the vertical direction (height direction) and horizontal direction (width direction) when the ventilator 1 is viewed from the air outlet side with the movable fins 12 held in the neutral position held horizontally.

The ventilator 1 of this embodiment has a fin member 10 (also called a fin assembly) having multiple movable fins 12, a pair of left and right decorative members 30 (also called decorative assemblies) arranged on both the left and right sides of the fin member 10 to form a design surface, and a case member 50 to which the fin member 10 and the left and right decorative members 30 are attached. This ventilator 1 is formed by assembling the fin member 10 and the left and right decorative members 30 to the case member 50.

In this embodiment, three movable fins 12 are rotatably arranged at the opening of the air outlet in the case member 50. The three movable fins 12 are also connected to each other by a link member (not shown) so that the rotation of each movable fin 12 is linked.

As shown in FIG. 3, the fin member 10 has a fin support section 11, a movable fin body section 13 of three movable fins 12, a fixed section 14 fixed to the fin support section 11, a plurality of cylindrical connecting pins 15 that rotatably connect each movable fin body section 13 to the fin support section 11, and an operating knob 16 attached to the movable fin body section 13 and the fixed section 14.

In this case, each movable fin 12 provided on the ventilator 1 is formed by a movable fin main body part 13 and a fixed part 14. The movable fins 12 of this embodiment include a first movable fin 12a disposed on the upper side, a second movable fin (operable movable fin) 12b disposed in the center, and a third movable fin 12c disposed on the lower side. has.

As shown in FIG. 3, the fin support portion 11 includes a plate-shaped upper support plate portion 11a and a lower support plate portion 11b, and a pair of left and right connecting columns 11c that connect the upper support plate portion 11a and the lower support plate portion 11b. and three pairs of left and right arm portions 11d extending forward from the left and right connecting columns 11c.

The upper surface of the upper support plate 11a and the lower surface of the lower support plate 11b are provided with two engagement protrusions 11e at predetermined positions, which are engaged with engagement holes 55 of the case member 50, which will be described later, when the fin member 10 is attached to the case member 50. In addition, the space surrounded by the upper support plate 11a, the lower support plate 11b, and the left and right connecting columns 11c is connected to a flow path 52 of the case member 50, which will be described later.

In the fin support portion 11 of this embodiment, the left and right arm portions 11d of each set are arranged at a constant interval from each other in the height direction. Furthermore, a space is provided in the width direction between the left and right arm parts 11d to allow insertion of the movable fin main body part 13. The left and right arm portions 11d of each set are configured such that when the movable fin body portion 13 is connected to the fin support portion 11, the inner surfaces of the left and right arm portions 11d are in contact with the left and right outer surfaces of the movable fin body portion 13. (see FIG. 5), or held slightly spaced apart.

The tip of each pair of left and right arm portions 11d is provided with a fixing protrusion to which the fixing portion 14 is fixed, and a first accommodating hole portion 11f into which the connecting pin 15 can be inserted and accommodated. The outer peripheral surface (fixing protrusion surface) of the fixing protrusion is formed into a curved surface that has an arc shape when viewed from the width direction, corresponding to the inner peripheral surface of the fixing portion 14 described later. Each first accommodating hole portion 11f is provided in the center of the arc-shaped outer peripheral surface of the fixing protrusion, and penetrates the tip of the arm portion 11d along the width direction.

The three movable fin main bodies 13 used in this embodiment have the same shape. Each movable fin body part 13 is formed along the width direction from the left and right side end surfaces of the fin base part 13a, the fin shaft part 13b protruding forward from the front end of the fin base part 13a, and the fin shaft part 13b. It has a second accommodation hole portion 13c. The movable fin main body portion 13 is formed so that a cross section perpendicular to the width direction has a constant shape, except for a portion where the second accommodation hole portion 13c is provided. Furthermore, the movable fin main body portion 13 has a laterally symmetrical shape and a vertically symmetrical shape.

As shown in FIG. 6, the fin base portion 13a has flat upper and lower surfaces that are arranged parallel to each other, and a rear end surface that curves convexly toward the rear. An inclined surface is formed at the front end of the fin base portion 13a so that the thickness (vertical dimension) gradually decreases toward the fin shaft portion 13b.

The fin shaft 13b is integrally formed with the fin base 13a as the rotation axis of the movable fin main body 13, and is provided straight along the left-right direction. The outer peripheral surface of the fin shaft 13b has an arc shape when viewed in a cross section perpendicular to the width direction of the fin shaft 13b (see Figures 6 to 8). The arc-shaped outer peripheral surface of the fin shaft 13b is provided over the entire width direction of the fin shaft 13b.

Furthermore, the fin shaft portion 13b is formed such that the arcuate outer circumferential surface extends over a range of over 180°, preferably over a range of 200° around the rotation axis (see FIG. 6). Thereby, the movable fin main body part 13 can be easily rotated with respect to the fixed part 14.

For example, in the case of this embodiment, the arcuate outer circumferential surface of the fin shaft portion 13b is continuously provided in a range of approximately 240° around the rotation axis of the movable fin main body portion 13. On the other hand, the arc-shaped fixing portion 14 is formed within a range of approximately 180° when viewed in a cross section perpendicular to the width direction of the fixing portion 14 . As a result, the movable fin main body part 13 can be rotated from the neutral position to approximately 30 degrees downward as shown in FIG. 7 with respect to the fixed part 14. It can be rotated upwards up to approximately 30 degrees. Here, rotating the movable fin main body 13 downward or upward means rotating the movable fin main body 13 so that the rear end portion of the movable fin main body 13 moves downward or upward.

As shown in FIG. 5, the second accommodating hole 13c of the movable fin main body 13 is a cylindrical hole that accommodates and holds the connecting pin 15, and is provided on the left and right side edges of the fin shaft 13b. The left and right second accommodating hole 13c are formed straight from the left and right side end faces of the fin shaft 13b toward the inside in the width direction so that the connecting pin 15 can be accommodated along the rotation axis of the movable fin main body 13.

The movable fin body 13 is rotatably connected to the arm 11d by receiving one connecting pin 15 through the first receiving hole 11f provided in the arm 11d and the second receiving hole 13c provided in the movable fin body 13. In this case, one movable fin body 13 is connected to a set of left and right arm portions 11d using a pair of left and right connecting pins 15.

The fixed part 14 of the movable fin 12 is arranged along the fin shaft part 13b, which is the rotation axis of the movable fin main body part 13, and when viewed in a cross section perpendicular to the width direction (see FIG. 6), the fixed part 14 is fixed. The inner circumferential surface and outer circumferential surface of the portion 14 have a substantially C-shaped shape that is an arc centered on the rotation axis of the movable fin main body portion 13 . As described above, this arc-shaped fixing portion 14 is formed in a range of approximately 180°. The arc-shaped outer circumferential surface of the fixing portion 14 is provided over the entire width of the fixing portion 14 .

The inner peripheral surface of the fixed part 14 is formed to correspond to the outer peripheral surface of the fin shaft part 13b, and has a shape that allows sliding contact with the fin shaft part 13b of the rotating movable fin main body part 13, or a shape that allows the fin shaft part 13b of the rotating movable fin main body part 13 to come into sliding contact with the fin shaft part 13b. It has a shape that allows it to maintain a slightly spaced close state. For example, in the case of this embodiment, the inner peripheral surface of the fixed part 14 and the fin shaft part 13b of the movable fin main body part 13 are in contact with each other along the rotation axis of the movable fin main body part 13, and the fin shaft part 13b are in contact with each other over the entire width direction. The fixing part 14 may be formed integrally with the fin support part 11, or may be formed separately from the fin support part 11 and attached to the tip of the arm part 11d of the fin support part 11 by adhesive or the like. It may be fixed.

The operation knob 16 is attached to the second movable fin 12b in the center, and has a U-shaped cross section perpendicular to the width direction. The operation knob 16 is attached to the movable fin main body 13 and/or the fixed part 14 so as not to impede the rotation of the second movable fin 12b. In this case, as shown in FIG. 6, at least a part of the movable fin main body 13 and the fixed part 14 are housed in the inner periphery of the operation knob 16. The first movable fin 12a and the third movable fin 12c in this embodiment are formed in a form in which the operation knob 16 is excluded from the second movable fin 12b.

Each of the left and right decorative members 30 includes a plate-shaped decorative base portion 31 that extends in the vertical direction, a decorative upper plate portion 32 that extends forward from the upper end of the decorative base portion 31, and a decorative base portion 32 that extends forward from the upper end of the decorative base portion 31. A decorative lower plate part 33 extending forward from the lower end of the part 31, and three decorative fins extending forward from the decorative base part 31 between the decorative upper plate part 32 and the decorative lower plate part 33. 34. Further, the upper surface of the decorative upper plate part 32 and the lower surface of the lower decorative plate part 33 are provided so that they engage with engagement holes 55 of the case member 50, which will be described later, when the decorative member 30 is attached to the case member 50. Two engaging protrusions 35 are provided at predetermined positions, respectively.

The three decorative fins 34 are arranged parallel to each other along the front-rear direction. The length of the decorative fins 34 extending forward from the decorative base portion 31 is the same as the length of the decorative fins 34 extending forward from the connecting posts 11c in the left and right arm portions 11d of the fin member 10. Each decorative fin 34 has a decorative fin main body portion 34a, an attachment portion 34b that protrudes forward from the front end of the decorative fin main body portion 34a, and a decorative garnish 34c that is attached to the attachment portion 34b.

The decorative fin body 34a is formed with the same thickness as the fin base 13a of the movable fin body 13. The mounting portion 34b is formed so that the cross section perpendicular to the width direction of the mounting portion 34b is semicircular. The decorative garnish 34c is attached to this semicircular mounting portion 34b.

The decorative garnish 34c has a substantially C-shaped shape when viewed in a cross section perpendicular to the width direction. Further, the decorative garnish 34c has a shape in which the outer circumferential surface of the decorative garnish 34c has the same arc shape as the outer circumferential surface of the fixed part 14 of the movable fin 12 when viewed in a cross section orthogonal to the width direction. In this embodiment, the outer circumferential surface of the decorative garnish 34c has, for example, a shape in which at least a portion of the decorative garnish 34c adjacent to the fixing part 14 has the same arc shape as the outer circumferential surface of the fixing part 14, or It may have an arcuate shape similar to the outer peripheral surface.

Further, the decorative garnish 34c is preferably made of the same or similar material as the fixed part 14 of the movable fin 12, and has the same or similar color and texture as the fixed part 14 of the movable fin 12. It is preferable that Thereby, the fixed part 14 of the movable fin 12 and the decorative garnish 34c can have the same appearance or a corresponding appearance that looks the same, thereby improving the appearance or appearance of the completed ventilator 1. Quality can be improved.

As shown in FIG. 2, the case member 50 of this embodiment has a flat case body 51, a cylindrical flow passage 52 connected to the center of the case body 51 in the width direction, a case upper plate 53 extending forward from the upper end of the case body 51, and a case lower plate 54 extending forward from the lower end of the case body 51.

The portion of the case body 51 to which the flow path 52 is connected is open. The flow path 52 of the case member 50 has a circulation space for circulating air supplied from an air conditioning device (not shown), and the circulation space communicates with a space surrounded by the upper support plate 11a and lower support plate 11b of the fin support part 11 and the left and right connecting posts 11c. The upper case plate 53 and the lower case plate 54 have engagement holes 55 for engaging the engagement protrusions 11e provided on the fin member 10 with the engagement protrusions 35 provided on the left and right decorative members 30 at positions corresponding to the engagement protrusions 11e, 35.

When assembling the ventilator 1 of this embodiment, first, the fin member 10 and the left and right decorative members 30 are each produced.
When manufacturing the fin member 10, the three movable fin main bodies 13 are rotatably connected to the fin support part 11 having the three fixed parts 14 integrated therewith.

Specifically, the corresponding movable fin main body part 13 is inserted between the pair of left and right arm parts 11d of the fin support part 11, and the first accommodation hole 11f of the arm part 11d and the second accommodation hole part 11f of the movable fin main body part 13 are inserted. The positions of the arm portion 11d and the movable fin main body portion 13 are adjusted so that the arm portion 11d and the movable fin body portion 13 are in direct communication with the accommodation hole portion 13c.

Then, the cylindrical connecting pin 15 is inserted and pushed from the outside of the width direction of the fin support part 11 toward the first housing hole 11f of the arm part 11d, so that the cylindrical connecting pin 15 is housed across both the first housing hole 11f and the second housing hole 13c, as shown in FIG. 5. By connecting one movable fin main body part 13 to the left arm part 11d with the connecting pin 15 and also to the right arm part 11d with the connecting pin 15, the movable fin main body part 13 is rotatably supported by the left and right arm parts 11d via the left and right connecting pins 15.

The above-mentioned work of connecting the movable fin main body 13 to the left and right arm portions 11d using the connecting pins 15 is performed on the three movable fin main body portions 13. This forms the first movable fin 12a and the third movable fin 12c. In addition, the second movable fin 12b is formed by attaching the operation knob 16 to the central movable fin main body portion 13 and the fixed portion 14. As a result, the fin member 10 shown in FIG. 2 is produced.

Furthermore, a pair of left and right decorative members 30 are produced in a step different from the production of the fin member 10 as described above. The left and right decorative members 30 are manufactured by fixing decorative garnishes 34c to the attachment portions 34b of the three decorative fins 34, respectively. Note that the method and means for fixing the decorative garnish 34c to the attachment portion 34b of the decorative fin 34 are not particularly limited.

After the fin member 10 and the left and right decorative members 30 are produced as described above, the obtained fin member 10 and the left and right decorative members 30 are assembled to the case member 50. In this case, the fin member 10 and the left and right decorative members 30 are inserted between the case upper plate portion 53 and the case lower plate portion 54 of the case member 50, respectively, and the engagement protrusions 11e, 35 provided on the fin member 10 and the left and right decorative members 30 are fitted into and engaged with the engagement holes 55 of the case member 50, respectively, thereby attaching the fin member 10 and the left and right decorative members 30 to one case member 50.

By performing the above-described steps, the fin member 10 of this embodiment including the first movable fin 12a to the third movable fin 12c is provided between the left and right decorative members 30 as shown in FIG. Ventilator 1 is manufactured. In particular, in this embodiment, the ventilator 1 can be manufactured by a relatively simple operation of assembling the independently formed fin member 10 and the decoration member 30 to the case member 50.

Further, in the ventilator 1 of this embodiment, as shown in FIG. 5, a gap is provided between the fin member 10 and the left and right decorative members 30. Note that the ventilator 1 of this embodiment may be formed without providing a gap between the fin member 10 and the decoration member 30.
The manufactured ventilator 1 shown in FIG. 1 is then attached to an interior member of an automobile.

As shown in Figs. 6 to 8, the ventilator 1 of this embodiment of the invention can rotate the movable fin body 13 of the movable fin 12 up and down by approximately 30° from the neutral position with respect to the fixed part 14, with the direction along the fin shaft 13b of the movable fin 12 and the connecting pin 15 as the rotation axis, thereby allowing the wind direction of the air blown out from the ventilator 1 to be adjusted up and down. The neutral position of the movable fin 12 refers to the position where the movable fin 12 is held parallel to the decorative fin 34. On the other hand, the fixed part 14 does not move up and down or forward and backward even if the movable fin body 13 is rotated up and down, and the fixed part 14 itself does not rotate.

In other words, the ventilator 1 of this embodiment has movable fins 12 formed by the movable fin main body 13 and the fixed part 14, so when the ventilator 1 is viewed from the air outlet side, it is possible to obtain a distinctive appearance with a simple structure in which the downstream end (fixed part 14) of the movable fin 12 does not appear to move or rotate when the movable fin 12 is rotated.

Furthermore, in the ventilator 1 shown in FIG. 1, the fixed part 14 of each movable fin 12 and the decorative garnish 34c of the left and right decorative members 30 are arranged in a straight line along the width direction, and are continuous. It looks like it's connected to. Therefore, the three movable fins 12 and the left and right decorative members 30 forming the design surface of the ventilator 1 can have a uniform appearance or a sense of unity. Furthermore, even if the movable fin main body section 13 is rotated, the fixed section 14 of the movable fin 12 does not move or rotate, so the sense of unity or unity between the fin member 10 and the decorative member 30 is not disrupted. , the improved appearance quality of the ventilator 1 can be maintained.

Although the ventilator 1 of the embodiment described above has three movable fins 12, in the present invention, the number of movable fins provided on the ventilator is not particularly limited, and the number of movable fins provided in the ventilator is not particularly limited. The number can be changed. Moreover, although the movable fins 12 are arranged along the width direction in the ventilator 1 of the embodiment, the ventilator may be formed by, for example, disposing the movable fins along the height direction.

In addition to the movable fins 12 arranged along the width direction as described in the embodiment, the ventilator of the present invention may also be provided with a plurality of upstream vertical fins arranged along the height direction upstream of the movable fins 12, as described in the above-mentioned Patent Document 1, for example. Alternatively, in addition to the movable fins 12 of the embodiment, a plurality of downstream vertical fins arranged along the height direction downstream of the movable fins 12 may be provided. Furthermore, the upstream vertical fins or downstream vertical fins provided in addition to the movable fins 12 may be installed so as to be rotatable in the left-right direction.
