Description

  The present invention relates to an air conditioning thin register that changes the direction of air conditioning air that is sent from an air conditioner and blows out from a rectangular outlet into a passenger compartment.

  An air conditioning register for changing the direction of air conditioning air sent from the air conditioner and blown into the passenger compartment is incorporated in the instrument panel of the vehicle. As one form of this air-conditioning register, there is a type in which the vertical and horizontal dimensions differ greatly, for example, a thin air-conditioning register whose horizontal dimension is larger than the vertical dimension (hereinafter referred to as “air-conditioning thin register”). ) Have been conventionally considered.

  One aspect of this air-conditioning thin register includes a retainer, a pair of auxiliary fins, and a main fin (see Patent Documents 1 to 3). The retainer has a rectangular tube shape whose left-right dimension is larger than the vertical dimension, and has a ventilation path for air-conditioning air. Moreover, the retainer has a blower outlet at the downstream end in the flow direction of the air-conditioning air. The blower outlet is formed in a rectangular shape whose dimension in the left-right direction is larger than that in the vertical direction.

  Each of the auxiliary fins and the main fins disposed between them extend in the left-right direction, and are supported by the fin shaft so as to be tiltable with respect to the left and right wall portions of the retainer. The main fin is provided with an operation member such as an operation knob that is operated when the main fin and the auxiliary fin are tilted.

  In the air-conditioning thin register having the above-described configuration, the air-conditioning air flowing through the ventilation path flows along the main fin and the auxiliary fins, and then blows out from the outlet. Further, when the operation member is operated and the main fin and both auxiliary fins are tilted, the air-conditioning air flows along the tilted main fin and both auxiliary fins. The air for air conditioning is blown out from the outlet in a direction different from that before the operation member is operated.

  In the air-conditioning thin register, as in a general non-thin air-conditioning register, components arranged in the ventilation path serve as ventilation resistance, resulting in an increase in pressure loss. There is an actual opening area as an index of the draft resistance. The actual opening area is the area where the various parts are not projected on the projection plane when a plane orthogonal to the ventilation direction is used as the projection plane at the outlet of the ventilation path. As the actual opening area decreases, the ventilation resistance increases and the pressure loss increases. Therefore, in order to suppress such an increase in pressure loss, it is important to reduce the area of the portion where the various components are projected on the projection surface.

  On the other hand, in the vehicle, the vertical dimension of the instrument panel tends to be reduced from the viewpoint of improving the design and the like, and accordingly, further thinning of the air conditioning thin register, that is, the vertical direction Therefore, it is required to further reduce the dimensions.

  However, with the thinning of the air conditioning thin register, the vertical dimension of the air outlet is also reduced. Therefore, the influence which the main fin and operation member located in the center of a ventilation path exert on the actual opening area of a blower outlet becomes large. Ventilation resistance increases, pressure loss increases, and noise such as wind noise generated when air-conditioning air is blown out from the outlet increases.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a thin air conditioning register that can reduce pressure loss and cope with further thinning. is there.

  An air conditioning thin register that solves the above-described problem is formed with an air passage having an air outlet at the downstream end in the flow direction of air conditioning air, and an inclined surface that is inclined with respect to the flow direction around the air outlet. The air outlet includes a retainer formed with a wall, and the air outlet extends in a direction orthogonal to the inclination direction in a state of being separated from each other on the inclined surface, and is longer than a pair of short sides extending along the inclination direction. A member having a pair of long sides and changing an angle formed with respect to the short side of the air-conditioning air blown out from the air outlet is a first fin, a second fin and a third extending respectively along the long side. The first fin is arranged upstream of the long side portion on the downstream side of the outlet and is supported by the retainer by a fin shaft at its downstream end, and the second fin Is The first fin is disposed upstream of the first fin and supported by the retainer by a fin shaft at the upstream end of the first fin, the third fin is disposed upstream of the long side on the upstream side of the outlet, and The first fin and the third fin are supported by the retainer by a fin shaft at the downstream end of the first fin, and between the operation member outside the air outlet and the three fins, according to the operation of the operation member. Is tilted in the same direction, and a transmission mechanism is provided for tilting the second fin in a direction opposite to the first and third fins.

  According to the above configuration, when the operation member is operated, the movement of the operation member is transmitted to each of the three fins by the transmission mechanism. By this transmission, the first fin and the third fin are tilted in the same direction with the fin shaft provided at the downstream end thereof as a fulcrum. Further, the second fin is tilted in the opposite direction to the first and third fins with the fin shaft provided at the upstream end as a fulcrum by the transmission.

  The air-conditioning air is a flow path between the second fin and the third fin tilted as described above and a flow path between the first fin and the third fin in the process of flowing through the ventilation path in the retainer. By flowing through, you can change the direction of flow. The air-conditioning air whose direction has been changed is then blown out from the outlet at the downstream end of the ventilation path. As a result, the angle formed with respect to the short side portion of the air-conditioning air blown out from the outlet is changed.

  In particular, when the angle is changed to a smaller side, the air-conditioning air blown from the air outlet flows along the inclined surface of the inclined wall portion inclined due to the Coanda effect. Therefore, there is no Coanda effect due to the inclined surface, and the blowing direction of the air-conditioning air is changed more greatly and the directivity is improved than when the angle is changed only by the three fins.

  Thus, since the blowing direction of the air-conditioning air from a blower outlet is changed, it extends to the direction along the same long side part between both long side parts of a blower outlet, and the flow direction (from a blower outlet) of air-conditioning air It is not necessary to separately provide fins for changing the angle formed with respect to the short side portion of the air-conditioning air to be blown out. In addition, the operation member is provided outside the air outlet.

  Therefore, the effect that the parts arranged in the ventilation path have on the actual opening area of the air outlet is that the fin extending in the direction along the long side portion is provided between the long side portions of the air outlet, or the fin It becomes smaller than the case where the operation member is provided.

  In addition, the 1st fin and the 2nd fin are arrange | positioned upstream of the long side part of the downstream in a blower outlet. Moreover, the 3rd fin is arrange | positioned upstream of the long side part of the upstream in a blower outlet. For this reason, the influence of these three fins on the actual opening area of the air outlet is smaller than when fins are provided between the long side portions of the air outlet.

  Therefore, the ventilation resistance by the components arranged in the ventilation path is smaller than that in the case where the fin is provided between the long side portions of the blowout port and the operation member is provided on the fin. As a result, pressure loss is reduced.

  In the air conditioning thin register, the operation member is supported by a support shaft extending along the long side portion so as to be tiltable with respect to the retainer, and the operation member is introduced into the ventilation path. The first fin, the second fin, and the third fin are tilted by the transmission mechanism so as to be in a posture along the flow direction. Is preferred.

  According to the above configuration, the operation member is tilted so as to be in a posture along the flow direction of the air-conditioning air introduced into the ventilation path, that is, the flow direction of the air-conditioning air before being changed by the three fins. Then, the three fins are tilted by the transmission mechanism so as to be in a posture along the flow direction. The flow path between the three fins is linear. Therefore, the air-conditioning air flows straight from the outlet to the downstream side by flowing along the three fins.

  In the air conditioning thin register, the operation member is supported by a support shaft extending along the long side portion so as to be tiltable with respect to the retainer, and the operation member is inclined along the inclined surface. The first fin and the third fin are tilted by the transmission mechanism so as to be inclined along the inclined surface, and the second fin is the transmission mechanism. Thus, it is preferable that the second fin is tilted so that the downstream end of the second fin is oriented toward the third fin.

  According to the above configuration, when the operation member is tilted so as to be inclined along the inclined surface of the inclined wall portion, the first fin and the third fin are moved along the inclined surface by the transmission mechanism. Tilt to tilt. The second fin located upstream of the first fin is tilted by the transmission mechanism so that the downstream end of the second fin is oriented toward the third fin. Therefore, the air for air conditioning can be changed in the direction toward the third fin by flowing along the second fin. The air for air conditioning is then changed along the inclined surface by flowing along the third fin and the first fin. And the air for an air conditioning is blown off in the direction in alignment with an inclined surface from a blower outlet. The air-conditioning air blown out flows along the inclined surface by the Coanda effect described above.

  In the air conditioning thin register, the operation member is supported to be tiltable with respect to the retainer by a support shaft extending along the long side portion, and the operation member is orthogonal or orthogonal to the inclined surface. When the first fin and the third fin are tilted so as to intersect with each other in a close state, the transmission mechanism is configured to intersect with the inclined surface in a state orthogonal or nearly orthogonal to the inclined surface. It is preferable that the second fin is tilted by the transmission mechanism so as to be inclined along the inclined surface.

  According to the above configuration, when the operation member is tilted so as to intersect with the inclined surface in a state orthogonal or nearly orthogonal, the first fin and the third fin are moved relative to the inclined surface by the transmission mechanism. It is tilted so as to be in a crossing posture in a state of being orthogonal or nearly orthogonal. The second fin is tilted by the transmission mechanism so as to be inclined along the inclined surface.

At this time, the third fin tries to prevent air-conditioning air from blowing straight between the second fin and the third fin.
Therefore, after the air for air conditioning flows between the 2nd fin and the 3rd fin, the direction is changed in the direction which inclines along an inclined surface by flowing along the 2nd fin. Thereafter, the air-conditioning air flows along the first fins, so that the direction of the air-conditioning air is changed in a direction orthogonal to the inclined surface or a direction intersecting with the state close to orthogonal. And the air for an air conditioning is blown off in the direction which cross | intersects the direction orthogonal to an inclined surface from a blower outlet, or the state near orthogonal.

  In the thin register for air conditioning, it is preferable that the third fin is disposed at an intermediate portion between the downstream end of the first fin and the upstream end of the second fin in the flow direction.

  According to said structure, a 3rd fin is located in the intermediate part of the downstream end of the 1st fin in the flow direction of air-conditioning air, and the upstream end of a 2nd fin. Therefore, a flow path is suitably formed between the second fin and the third fin, and a flow path is suitably formed between the third fin and the first fin. In this manner, an air conditioning air flow path is suitably formed between the three fins. In addition, when the operation member is operated and the three fins are tilted, the shape of the flow path formed between the three fins is suitably changed.

  According to the thin register for air conditioning, it is possible to reduce pressure loss and cope with further thinning.

Hereinafter, an embodiment embodied in a thin air conditioning register for a vehicle will be described with reference to the drawings.
In the following description, it is assumed that the traveling direction (forward direction) of the vehicle is the front, the backward direction is the rear, and the height direction is the vertical direction. Moreover, about a vehicle width direction (left-right direction), a direction is prescribed | regulated on the basis of the case where a vehicle is seen from back.

  In the passenger compartment, an instrument panel is provided in front of the front seats (driver's seat and front passenger seat) of the vehicle, and a thin air conditioning register is incorporated in the center, side, etc. in the left-right direction (vehicle width direction). ing. The main function of the air conditioning thin register is to change the direction of the air conditioning air sent from the air conditioner and blown into the passenger compartment, as in a general non-thin air conditioning register.

  However, the thin air-conditioning register is incorporated in the instrument panel at a position lower than a general non-thin air-conditioning register. For example, when an occupant having the same physique as a crash test dummy is seated in the front seat of the vehicle, the air conditioning thin register of the present embodiment is about the same height as that of the occupant. In the instrument panel.

  As shown in FIGS. 1 to 4, the air conditioning thin register includes a retainer 10, a downstream fin group, an upstream fin group, an operation member 65, a transmission mechanism 80, and an upstream transmission mechanism 85. Next, the configuration of each part constituting the thin air conditioning register will be described.

<Retainer 10>
The retainer 10 is for connecting a ventilation duct (not shown) of an air conditioner and an opening (not shown) provided in the instrument panel, and includes an upstream retainer 11, a downstream retainer 15, and a bezel 20. . The internal space of the retainer 10 constitutes a flow path (hereinafter referred to as “ventilation path 30”) of air-conditioning air A1 (see FIG. 6). Here, regarding the flow direction of the air conditioning air A1, the side close to the air conditioner is referred to as “upstream”, “upstream side”, etc., and the side far from the air conditioner is referred to as “downstream”, “downstream side”, etc. .

  As shown in FIGS. 4A, 4 </ b> B, and 6, the upstream retainer 11 is a member that constitutes the most upstream portion of the retainer 10. The upstream retainer 11 has a square cylindrical shape with the upstream end and the downstream end being opened and having a dimension in the left-right direction (vehicle width direction) larger than the dimension in the vertical direction.

  As shown in FIGS. 2 and 6, the downstream retainer 15 is disposed on the downstream side of the upstream retainer 11. Similar to the upstream retainer 11, the main part of the downstream retainer 15 has a substantially rectangular tube shape with the upstream end and the downstream end being opened and the dimension in the left-right direction (vehicle width direction) being larger than the dimension in the vertical direction. . The downstream retainer 15 is locked to a locking projection 12 (see FIG. 4A) provided at a corresponding position of the upstream retainer 11 in a locking hole 16 provided at the upstream end of the downstream retainer 15. Thus, the upstream retainer 11 is connected.

  The bezel 20 is a member constituting the most downstream part of the retainer 10. The bezel 20 is connected to the downstream retainer 15 by being locked to locking protrusions 17 provided at corresponding positions of the downstream retainer 15 in locking holes 21 provided at a plurality of positions.

As shown in FIGS. 1 and 5, the bezel 20 is formed with an outlet 22 that forms the downstream end of the ventilation path 30 and from which the air-conditioning air A <b> 1 is blown out.
An inclined wall portion 26 is formed around the air outlet 22 in the bezel 20. The downstream surface of the inclined wall portion 26 is an inclined surface 26a that is inclined with respect to the flow direction. The inclined surface 26a constitutes a part of the design surface of the air conditioning thin register. Here, the inclined surface 26a is inclined so as to become higher toward the downstream side (see FIG. 8 and the like).

  The air outlet 22 includes a pair of short side portions 23 and a pair of long side portions 24 and 25 longer than each short side portion 23. Both short side portions 23 extend along the inclined direction in the inclined surface 26a while being spaced apart from each other in parallel. Both long side portions 24 and 25 extend in the left-right direction (vehicle width direction), which is a direction orthogonal to the tilt direction, in a state of being spaced apart in parallel from each other on the inclined surface 26a. Since the inclined surface 26a is inclined as described above, the lower long side portion 24 is positioned upstream of the upper long side portion 25 (see FIG. 8 and the like).

By the both short side portions 23 and the long side portions 24 and 25, the air outlet 22 has a horizontally long rectangular shape elongated in the left-right direction (vehicle width direction) rather than the direction along the inclined direction of the inclined surface 26a.
In the bezel 20, a window portion 27 made of a rectangular hole is formed at a position slightly away from the air outlet 22 in one of the left and right directions (vehicle width direction) (rightward).

  As shown in FIGS. 6 and 8, the ventilation path 30 is surrounded by four wall portions of the retainer 10. These four wall portions are composed of a pair of side wall portions 31 and 32 facing each other in the left-right direction (vehicle width direction), and an upper wall portion 33 and a bottom wall portion 36 facing each other in the vertical direction. Both side wall portions 31 and 32 face each other in a state of being parallel to each other or a state close thereto.

  As shown in FIGS. 8 to 10, the shape of the upper wall portion 33 is different between the upstream portion and the downstream portion. The upstream portion of the upper wall portion 33 is configured by a flat general wall portion 34. The general wall portion 34 is located at a location spaced upstream from the upper long side portion 25. The downstream portion of the upper wall portion 33 is configured by an upper bulging wall portion 35 that bulges upward from the general wall portion 34, which is the side farther from the ventilation path 30. The space surrounded by the upper bulging wall portion 35 and the bezel 20 has an upper tilt space ST that allows a first fin 50 and a second fin 54 described later to tilt upward from the general wall portion 34. It is composed.

  Further, the upstream portion of the bottom wall portion 36 is constituted by a general wall portion 37 that is substantially parallel to the general wall portion 34. The general wall portion 37 is located at a location spaced upstream from the lower long side portion 24. The downstream portion of the bottom wall portion 36 is constituted by a lower bulging wall portion 38 that bulges downward from the general wall portion 37, which is the side farther from the ventilation path 30. The space surrounded by the lower bulging wall portion 38 and the bezel 20 constitutes a lower tilt space SB that allows a later-described third fin 58 to tilt downward relative to the general wall portion 37. .

As shown in FIGS. 2, 3, and 8, the left and right side wall portions 31, 32 of the retainer 10 are provided with three types of bearing portions 41, 42, 43, respectively.
The bearing portion 41 is provided between the downstream end of the downstream retainer 15 and the bezel 20, upstream of the long side portion 25, and at a location close to the long side portion 25. The bearing portion 42 is the downstream retainer 15 and is provided at a location upstream of the long side portion 24 and close to the long side portion 24. The bearing portion 43 is the downstream retainer 15 and is provided at a location spaced upstream from the bearing portion 41.

Bearing portions 44 are respectively provided at a plurality of locations separated at equal intervals. In the present embodiment, the bearing portion 44 of the upper wall portion 33 and the bearing portion 44 of the bottom wall portion 36 are provided at the boundary portion between the downstream end portion of the upstream retainer 11 and the upstream end portion of the downstream retainer 15. .

  Further, in the upstream retainer 11, a support piece 13 is formed at a location where the bearing portion 44 of the upper wall portion 33 and the bearing portion 44 of the bottom wall portion 36 are sandwiched from both the upper and lower sides. In each support piece 13, a hole 14 is formed at a location that is collinear with the central axis of the bearing portion 44.

The fin shaft 55 is supported by the side wall portions 31 and 32 by the bearing portion 43 of the retainer 10. Reinforcing ribs 56 are formed at a plurality of locations separated from each other in the left-right direction (vehicle width direction) of the second fin 54 in order to increase the rigidity of the second fin 54.

  The third fin 58 is disposed in the vicinity of the upstream side of the long side portion 24. The third fin 58 is gently curved so as to swell slightly downward. A fin shaft 59 extending in the left-right direction (vehicle width direction) along the long side portion 24 is provided at the downstream end of the third fin 58. The fin shaft 59 is supported by the side wall portions 31 and 32 by the bearing portion 42 of the retainer 10.

<Upstream fin group>
As shown in FIG. 6, the upstream fin group is for changing an angle β formed with respect to the long side portions 24 and 25 of the air-conditioning air A <b> 1 blown out from the air outlet 22. As shown in FIGS. 4A, 4 </ b> B, and 9, the upstream fin group includes a plurality of upstream fins 62 disposed upstream of the second fins 54 in the ventilation path 30. Each upstream fin 62 has the same configuration. Each of the upstream fins 62 is configured by a plate-like body that extends in the vertical direction within the ventilation path 30. The plurality of upstream fins 62 are arranged in the left-right direction (vehicle width direction) so as to be spaced apart from each other at substantially equal intervals.

  Each upstream fin 62 includes a fin shaft 63 extending in the vertical direction. The fin shaft 63 is located substantially at the center of the upstream fin 62 with respect to the flow direction of the air-conditioning air A1. The fin shaft 63 for each upstream fin 62 is supported on the upper wall portion 33 and the bottom wall portion 36 by the bearing portion 44. The upper and lower ends of the fin shaft 63 for each upstream fin 62 are formed in a conical shape, and are inserted and supported in the holes 14 of the support piece 13 in this portion.

  Further, a fan-like driven gear 64 is formed at the upper end of the fin shaft 63 for each upstream fin 62. Each tooth of the driven gear 64 is arranged along an arc centered on the fin shaft 63.

<Operation member 65>
As shown in FIGS. 1 and 3, the operation member 65 is a member that is operated by the occupant when changing the blowing direction of the air-conditioning air A <b> 1 from the air outlet 22.

  As shown in FIGS. 3 and 13, an auxiliary side wall 71 is provided in parallel to the side wall 32 at a position away from the side wall 32 of one side of the retainer 10 (to the right in FIG. 3) in the same direction. Is formed. A lateral wall portion 72 formed in parallel to the general wall portions 34 and 37 of the retainer 10 is bridged between the side wall portion 32 and the auxiliary side wall portion 71.

  A shaft member 73 is disposed between the side wall portion 32 and the auxiliary side wall portion 71 and downstream of the lateral wall portion 72. The shaft member 73 is rotatably supported with respect to the side wall portion 32 and the auxiliary side wall portion 71. More specifically, the main part of the shaft member 73 is constituted by a shaft main body 74 that is elongated in the left-right direction (vehicle width direction). A support shaft 75 extending in the left-right direction (vehicle width direction) along the long side portions 24 and 25 of the outlet 22 is formed at the downstream end portion of the shaft main body 74 (FIGS. 7A and 7B). )reference). On the other hand, support holes 76 are respectively penetrated at the downstream end portions of the side wall portion 32 and the auxiliary side wall portion 71, more specifically at locations slightly away from the bearing portion 41 upstream. Each shaft 75 is engaged with the support hole 76, so that the shaft member 73 is supported by the side wall portion 32 and the auxiliary side wall portion 71.

A cylindrical portion 77 that protrudes downward is formed at a central portion of the shaft main body portion 74 in the left-right direction (vehicle width direction).
Many portions of the operation member 65 are constituted by an operation main body portion 66 having a semi-disc shape in plan view. A part of the operation main body 66 is exposed to the downstream side through the window 27 of the bezel 20 (see FIG. 1), and the vehicle occupant can touch the exposed portion to operate the operation member 65. .

  A hole 67 penetrating in the vertical direction is formed in the operation main body 66, and the cylindrical portion 77 is inserted through the hole 67. Therefore, the operation member 65 can tilt in the direction along the short side portion 23 of the air outlet 22 with respect to the retainer 10 with the left and right support shafts 75 of the shaft member 73 as fulcrums, and the cylindrical portion. It is possible to tilt the shaft member 73 in the direction along the long sides 24 and 25 (left and right direction, vehicle width direction) with respect to the shaft member 73, with 77 as a fulcrum.

  On one (right side) side wall portion 32 of the retainer 10, a long hole 81 that is curved so as to swell upstream is formed along an arc centered on the support hole 76, substantially above the bearing portion 42. Yes. In addition, a connecting pin 82 that protrudes toward the side wall 32 is provided upstream of the support shaft 75 in the shaft main body 74 (see FIGS. 7A and 7B). The connecting pin 82 is inserted into the long hole 81 and the tip portion is exposed to the ventilation path 30. A transmission member 83 having a long plate shape is connected (fixed in this embodiment) to the exposed portion of the connection pin 82 at an intermediate portion in the length direction. The transmission member 83 is arranged in an inclined posture so as to become higher toward the downstream side.

  A pin 53 projects from a side surface of one side (right side) of the first fin 50 and upstream of the fin shaft 51. Further, a pin 60 projects from a side surface of one side (right side) of the third fin 58 and upstream of the fin shaft 59. And the pin 53 of the 1st fin 50 is connected with the end part of the downstream of the transmission member 83 so that rotation is possible. Further, the pin 60 of the third fin 58 is rotatably connected to the upstream end of the transmission member 83.

  As shown in FIGS. 2A and 12, in the left-right direction (vehicle width direction), a fan-shaped drive gear 61 is formed at the end (left end) of the third fin 58 opposite to the pin 60. Is provided. A fan-like driven gear 57 is provided at the end (left end) on the same side as the drive gear 61 in the second fin 54. Each tooth of the drive gear 61 is arranged along an arc centered on the fin shaft 59 of the third fin 58. Each tooth of the driven gear 57 is arranged along an arc centered on the fin shaft 55 of the second fin 54. The drive gear 61 and the driven gear 57 are meshed with each other.

<Upstream transmission mechanism 85>
As shown in FIG. 3 and FIGS. 4A and 4B, the upstream transmission mechanism 85 causes movement in the direction along the long sides 24 and 25 of the operation member 65 (rotation in the left-right direction) to a plurality of upstream positions. It is a mechanism for transmitting to each fin 62 and tilting each upstream fin 62 with the fin shaft 63 as a fulcrum.

  A transmission gear 68 is formed at the upstream end of the operation main body 66. Each tooth of the transmission gear 68 is arranged along an arc centered on the hole 67. Each tooth of the transmission gear 68 is curved so as to bulge upstream along an arc centered on the support shaft 75 of the shaft member 73.

A regulating projection 78 projects upward from the upstream portion of the lateral wall portion 72.
In the upper wall portion 33 of the retainer 10, an elongated gear member 86 is disposed in the left-right direction (vehicle width direction) at the boundary portion with the upper bulging wall portion 35 of the general wall portion 34 (see FIG. 10). One end (right end) of the gear member 86 is positioned on the lateral wall 72. A restriction hole 87 extending in the left-right direction (vehicle width direction) is formed in the right end portion of the gear member 86, and the restriction protrusion 78 is inserted into the restriction hole 87 (FIG. 7A, (See (b)). These restriction holes 87 and restriction protrusions 78 allow the gear member 86 to slide in the left-right direction (vehicle width direction) while restricting movement of the gear member 86 in the flow direction of the air-conditioning air A1.

  In addition, the restriction | limiting which accept | permits the movement of the left-right direction (vehicle width direction) with the general wall part 34 is controlled in the several places of the left-right direction (vehicle width direction) in the downstream retainer 15 while the upward movement of the gear member 86 is controlled. A piece 18 is provided (see FIG. 10).

  A rack gear 88 is formed in an upstream portion of the gear member 86 and wide in the left-right direction excluding the right end portion, and a fan-like driven gear 64 for each upstream fin 62 is meshed with the rack gear 88. A rack gear 89 is formed at the downstream portion of the right end portion of the gear member 86. The teeth of the rack gears 88 and 89 are arranged along the left-right direction (vehicle width direction).

  As shown in FIGS. 3, 7 (a), 7 (b), and 13, a recess 79 is formed in the lateral wall portion 72 on the downstream side of the restricting protrusion 78, and a bearing member is formed in the recess 79. 91 is fitted. The bearing member 91 is configured to transmit to the gear member 86 the rotation in the direction along the long side portions 24 and 25 of the operation member 65 with the cylindrical portion 77 serving as a fulcrum (left and right direction, vehicle width direction). A pinion gear 92 is supported. More specifically, the pinion gear 92 includes a disc main body 93 and a shaft 94 extending downward from the gear main body 93. The shaft portion 94 is inserted into the bearing member 91 and penetrates the bottom portion of the recess 79. A retaining ring 95 is locked to the lower end portion of the shaft portion 94 exposed downward from the lateral wall portion 72, and the retaining portion 95 is prevented from coming out of the bearing member 91. Further, the gear main body 93 meshes with the transmission gear 68 of the operation member 65 from the upstream side and meshes with the rack gear 89 from the downstream side. Note that the bearing member 91 has a function of supporting the shaft portion 94 of the pinion gear 92 and gives a sliding resistance to the coaxial portion 94 to rotate the operation member 65 in the direction along the long side portions 24 and 25. It also has a function of making the operation load when it is appropriate to have an appropriate magnitude.

As described above, the thin air-conditioning register of this embodiment is configured. Next, the operation of the air conditioning thin register will be described.
8 to 13 show the state of each part when the operation member 65 is in a posture (horizontal state) along the flow direction of the air-conditioning air A1 introduced into the ventilation path 30. FIG. At this time, as shown in FIG. 11, if the connecting pin 82 is positioned upstream of the support hole 76 and the expression is changed, the connecting pin 82 is positioned at the center in the vertical direction of the long hole 81. The downstream end of the transmission member 83 is located upstream of the fin shaft 51 of the first fin 50, and the upstream end of the transmission member 83 is located upstream of the fin shaft 59 of the third fin 58.

  In the first fin 50, the pin 53 is located upstream of the fin shaft 51. In the third fin 58, the pin 60 is located upstream of the fin shaft 59. The first fin 50 is in a state of being substantially parallel to the general wall portion 34 of the upper wall portion 33 at a boundary portion with the ventilation path 30 of the upward tilting space ST. Further, the third fin 58 is in a state of being substantially parallel to the general wall portion 37 of the bottom wall portion 36 at a boundary portion with the ventilation path 30 of the downward tilting space SB.

  Further, as shown in FIG. 12, the drive gear 61 of the third fin 58 meshes with the driven gear 57 of the second fin 54 in the circumferential intermediate portion in the circumferential intermediate portion. The second fin 54 is in a state of being substantially parallel to the general wall portion 34 of the upper wall portion 33 at a boundary portion with the ventilation path 30 of the upward tilting space ST.

  As described above, the first to third fins 50, 54, 58 are in a posture along the flow direction of the air-conditioning air A <b> 1 introduced into the ventilation path 30 (a posture substantially parallel to the general wall portions 34, 37). . Therefore, as shown in FIG. 8, the air-conditioning air A <b> 1 flows along the second fin 54 and the third fin 58 in the flow path between the second fin 54 and the third fin 58. Thereafter, the air-conditioning air A <b> 1 flows along the first fin 50, and is blown straight out from the outlet 22 to the downstream side.

  At this time, the downstream end of the first fin 50 approaches the long side portion 25, and the upstream end of the second fin 54 approaches the boundary portion between the upper bulging wall portion 35 and the general wall portion 34. Further, the upstream end of the first fin 50 and the downstream end of the second fin 54 are close to each other. Therefore, the upward tilting space ST is in a state of being blocked by the first fin 50 and the second fin 54 at the boundary portion with the ventilation path 30. Therefore, the air-conditioning air A1 flowing into the upward tilting space ST is small.

  Further, the downstream end of the third fin 58 approaches the long side portion 24, and the upstream end approaches the boundary portion between the lower bulging wall portion 38 and the general wall portion 37. Therefore, the downward tilting space SB is in a state of being blocked by the third fin 58 at the boundary portion with the ventilation path 30. Therefore, the air conditioning air A1 flowing into the downward tilting space SB is small.

  11 and 13, when an upward force is applied to a portion of the operation member 65 that is exposed downstream from the window portion 27, the operation member 65 is supported by the shaft member 73. It tilts clockwise in FIG. 13 with the shaft 75 as a fulcrum. The operation member 65 is inclined higher toward the downstream side. With the tilting, the connecting pin 82 moves downward in the long hole 81 in FIG. Accordingly, the transmission member 83 translates downward while maintaining an inclined posture. By this parallel movement, the downstream end of the transmission member 83 is moved upstream of the fin shaft 51 of the first fin 50 to a position lower than the fin shaft 51. Further, the upstream end of the transmission member 83 moves to a position lower than the fin shaft 59 upstream of the fin shaft 59 of the third fin 58.

The first fin 50 tilts counterclockwise in FIG. 11 with the fin shaft 51 as a fulcrum. By this tilting, the first fin 50 is tilted so as to become lower toward the upstream side.
The third fin 58 tilts counterclockwise in FIG. 11 with the fin shaft 59 as a fulcrum. By this tilting, the third fin 58 is tilted so as to become lower toward the upstream side in the downward tilting space SB, like the first fin 50.

  When the third fin 58 tilts as described above, the meshing position of the drive gear 61 of the third fin 58 and the driven gear 57 of the second fin 54 changes in FIGS. 12 and 16, and the second fin 54 is shown in FIG. 12 and in the counterclockwise direction of FIG. By this tilting, the second fin 54 is tilted so as to become lower toward the downstream side.

  As shown in FIG. 14, when the operation member 65 is tilted to the upper end of the movable range with the support shaft 75 as a fulcrum, the connecting pin 82 is moved to the lower end in the long hole 81 as shown in FIG. Reach the department. At this time, the inclination angle of the first fin 50 is smaller than the inclination angle of the inclined surface 26 a of the bezel 20. Further, the third fin 58 approaches the bottom of the inclined wall portion 26 in a state of being substantially parallel to the first fin 50. The downstream end of the second fin 54 is oriented toward the downstream end of the third fin 58. The flow path between the three fins 50, 54, and 58 changes to a shape different from the linear flow path in FIG.

  Therefore, the air-conditioning air A <b> 1 can be changed in a downward direction, which is a direction toward the third fin 58, by flowing along the second fin 54 as indicated by an arrow in FIG. 17. The air conditioning air A <b> 1 then flows along the third fins 58, so that the direction can be changed obliquely upward. The air-conditioning air A1 that has passed through the flow path between the downstream end of the second fin 54 and the downstream end of the third fin 58 flows along the first fin 50 that is in a substantially parallel relationship with the third fin 58. . The air-conditioning air A <b> 1 flows in the direction along the inclined surface 26 a of the inclined wall portion 26 by flowing along the third fin 58 and the first fin 50 in this way. The air conditioning air A1 is blown out from the blowout port 22 in a direction along the inclined surface 26a. The air-conditioning air A1 blown out flows along the inclined surface 26a due to the Coanda effect. The Coanda effect is the property of a fluid that attempts to flow along an object when a substance is placed in the flow.

  Here, the downstream end of the first fin 50 approaches the long side portion 25 of the air outlet 22. For this reason, air-conditioning air A1 flows along the inclined surface 26a immediately after being blown out from the air outlet 22. Therefore, the Coanda effect is more effectively exhibited.

  There is no Coanda effect due to the inclined surface 26a, and the blowing direction of the air-conditioning air A1 is changed more greatly than when the flow direction is changed only by the three fins 50, 54, and 58.

  Therefore, although the air outlet 22 of the air-conditioning thin register is located in front of the occupant in the passenger compartment (in front of the groove), the air-conditioning air A1 is directed to the upper part of the occupant, for example, the head. Even flowing.

  Contrary to the above, when a downward force is applied to the portion of the operation member 65 exposed from the window 27 to the downstream side from the state of FIGS. 11 and 13, the operation member 65 is It tilts counterclockwise in FIG. 13 with the support shaft 75 of the shaft member 73 as a fulcrum. The operation member 65 is in a lower inclined state toward the downstream side. With the tilting, the connecting pin 82 moves upward in the long hole 81 in FIG. Accordingly, the transmission member 83 translates upward while maintaining the inclined posture. By this parallel movement, the downstream end of the transmission member 83 is moved upstream of the fin shaft 51 of the first fin 50 and higher than the fin shaft 51. Further, the upstream end of the transmission member 83 moves upstream of the fin shaft 59 of the third fin 58 and higher than the fin shaft 59.

  The first fin 50 tilts clockwise in FIG. 11 with the fin shaft 51 as a fulcrum. By this tilting, the first fin 50 is tilted so as to become higher toward the upstream side in the upward tilting space ST.

  The third fin 58 moves in the clockwise direction in FIG. 11 with the fin shaft 59 as a fulcrum. Due to this tilting, the third fin 58 is inclined so as to become higher toward the upstream side, like the first fin 50.

  When the third fin 58 tilts as described above, the meshing position of the drive gear 61 of the third fin 58 and the driven gear 57 of the second fin 54 changes in FIGS. Tilt in the clockwise direction of FIGS. Due to this tilting, the second fin 54 is tilted so as to become higher toward the downstream side in the upward tilting space ST.

  As shown in FIG. 18, when the operation member 65 is tilted to the lower end of the movable range with the support shaft 75 of the shaft member 73 as a fulcrum, as shown in FIG. The upper end of the hole 81 is reached. The operation member 65 has a posture that intersects the inclined surface 26a in a state of being orthogonal or nearly orthogonal. The first fin 50 intersects the inclined surface 26 a in the vicinity of the upstream side of the long side portion 25 in a state of being orthogonal or nearly orthogonal. The third fin 58 is substantially parallel to the first fin 50 in the vicinity of the upstream side of the long side portion 24 and intersects the inclined surface 26a in a state of being orthogonal or nearly orthogonal. The second fins 54 are inclined along the inclined surface 26a. The flow path between the three fins 50, 54, and 58 changes to a shape different from the flow path in FIGS.

  Here, as shown in FIG. 21, the third fin 58 is such that the air-conditioning air A1 blows straight between the second fin 54 and the third fin 58, that is, by the three fins 50, 54, 58. It tries to prevent maintaining the direction (direction along the general wall portions 34 and 37) before the direction is changed.

  Accordingly, as indicated by the arrows in FIG. 21, when the air-conditioning air A1 flows through the flow path between the second fin 54 and the third fin 58, the upstream end of the third fin 58 and the second fin 54 It flows in the direction along the normal line N of the arc C connecting the fin shaft 55 of the arc. The air-conditioning air A1 is once changed in the upward direction as described above, and flows along the second fin 54 inclined so as to become higher toward the downstream side. This phenomenon is also due to the Coanda effect. Thereafter, the air-conditioning air A1 flows along the first fins 50, so that the direction of the air-conditioning air A1 is changed to a direction orthogonal to the inclined surface 26a or a direction intersecting with the state close to orthogonal. The air-conditioning air A1 is blown obliquely downward from the air outlet 22.

  At this time, both the downstream end of the second fin 54 and the upstream end of the first fin 50 approach the highest place in the upper bulging wall portion 35. Therefore, the amount of air-conditioning air A1 flowing between the downstream end of the second fin 54 and the above-mentioned portion of the upper bulging wall portion 35 is small. Further, the amount of air-conditioning air A1 flowing between the upstream end of the first fin 50 and the above-mentioned portion of the upper bulging wall portion 35 is small.

  Further, as shown in FIGS. 14 and 18, the operation member 65 is accompanied by a shaft member 73, and the direction along the short side portion 23 of the air outlet 22 (substantially up and down) with the support shaft 75 of the shaft member 73 as a fulcrum. When the transmission gear 68 is tilted in the same direction, the transmission gear 68 of the operation member 65 is also tilted in the same direction around the support shaft 75. The direction of the tilt is a direction along the tooth trace of each tooth of the transmission gear 68 and the pinion gear 92. Therefore, the transmission gear 68 slides with respect to the teeth of the pinion gear 92 engaged therewith. Therefore, the tilting of the operation member 65 in the above direction is not transmitted to the pinion gear 92.

  By the way, as shown in FIGS. 6 and 7A and 7B, the operation member 65 rotates in the direction along the long side portions 24 and 25 (left and right direction, vehicle width direction) with the cylindrical portion 77 as a fulcrum. Then, the transmission gear 68 turns around the cylindrical portion 77 accordingly. The meshing position of the transmission gear 68 with the pinion gear 92 changes. The pinion gear 92 rotates, and the meshing position of the gear member 86 of the pinion gear 92 with the rack gear 89 changes. The gear member 86 moves in the left-right direction (vehicle width direction), and the meshing position of the rack gear 88 with the plurality of driven gears 64 in the gear member 86 changes. Each driven gear 64 rotates in the same direction, and the upstream fin 62 coaxial with the driven gear 64 tilts in the same direction with the fin shaft 63 as a fulcrum as shown by a two-dot chain line in FIG. 6, for example. The air-conditioning air A1 flowing into the ventilation path 30 flows along the upstream fins 62 tilted as described above, so that the flowing direction (angle β formed with respect to the long side portions 24 and 25) can be changed.

According to the embodiment described in detail above, the following effects can be obtained.
(1) The air outlet 22 of the retainer 10 has a pair of long side portions 24 and 25 extending in a direction orthogonal to the inclined direction in a state of being separated from each other on the inclined surface 26a of the inclined wall portion 26 and the same in a state of being separated from each other It is comprised by a pair of short side part 23 extended along an inclination direction (FIG. 1, FIG. 5).

  The members that change the angle α formed with respect to the short side portion 23 of the air-conditioning air A1 blown from the air outlet 22 are the first fin 50, the second fin 54, and the third fin 58 that extend along the long side portions 24 and 25, respectively. (FIG. 8).

  The 1st fin 50 is arrange | positioned upstream from the long side part 25 of the downstream in the blower outlet 22, and is supported by the retainer 10 with the fin axis | shaft 51 of an own downstream end. The second fin 54 is disposed upstream of the first fin 50 and is supported by the retainer 10 by the fin shaft 55 at its upstream end. The 3rd fin 58 is arrange | positioned upstream from the long side part 24 of the upstream in the blower outlet 22, and is supported by the retainer 10 by the fin axis | shaft 59 of an own downstream end.

  In accordance with the operation of the operation member 65, the first fin 50 and the third fin 58 are tilted in the same direction between the operation member 65 provided outside the air outlet 22 and the three fins 50, 54, 58. Then, a transmission mechanism 80 that tilts the second fin 54 in the direction opposite to the first fin 50 and the third fin 58 is provided (FIG. 11).

  Therefore, by operating the operation member 65, the three fins 50, 54, 58 are tilted to change the shape of the flow path between the three fins 50, 54, 58, and the air conditioner that blows out from the air outlet 22. The angle α formed with respect to the short side portion 23 of the working air A1 can be changed. In particular, when the angle α is changed to a smaller side (FIG. 17), the air-conditioning air A1 blown from the air outlet 22 can flow along the inclined surface 26a due to the Coanda effect. The direction of the working air A1 can be greatly changed obliquely upward to improve the directivity.

  Therefore, in order to change the blowing direction of the air-conditioning air A1, it is not necessary to provide a fin in the central portion between the long side portions 24 and 25, or to provide an operating member on the fin, and the pressure loss is reduced. Reduction can be achieved, and further reduction in thickness of the air conditioning thin register can be dealt with.

Further, since the ventilation resistance and the pressure loss are reduced, noise such as wind noise generated when the air-conditioning air A1 is blown out from the air outlet 22 can be reduced.
(2) The operation member 65 is supported so as to be tiltable with respect to the retainer 10 by a support shaft 75 extending along the long side portions 24 and 25 (FIGS. 1 and 3).

  When the operation member 65 is tilted so as to be in a posture along the flow direction of the air-conditioning air A <b> 1 introduced into the ventilation path 30, the three fins 50, 54, and 58 are caused to flow by the transmission mechanism 80. It tilts so that it may become the attitude | position along a direction (FIG. 11).

Therefore, the flow path between the three fins 50, 54, 58 can be made linear, and the air for air conditioning A 1 can be blown straight out from the outlet 22 to the downstream side.
(3) When the operation member 65 is tilted so as to be inclined along the inclined surface 26a, the first fin 50 and the third fin 58 are inclined along the inclined surface 26a by the transmission mechanism 80. Tilt to position. The second fin 54 is tilted by the transmission mechanism 80 so that the downstream end of the second fin 54 faces the third fin 58 (FIG. 15).

  Therefore, the air-conditioning air A <b> 1 can flow toward the third fin 58 by flowing along the second fin 54. Thereafter, the air conditioning air A1 is allowed to flow along the third fins 58 and the first fins 50, whereby the air conditioning air A1 can be blown out from the air outlet 22 in the direction along the inclined surface 26a. Furthermore, the air-conditioning air A1 can be caused to flow along the inclined surface 26a by the Coanda effect, and the directivity of the air-conditioning air A1 heading obliquely upward can be improved.

  (4) When the operation member 65 is tilted so as to intersect with the inclined surface 26a in a state of being orthogonal or nearly orthogonal, the first fin 50 and the third fin 58 are inclined by the transmission mechanism 80. It is tilted so as to be in a posture that intersects with or near to the angle 26a. The second fin 54 is tilted by the transmission mechanism 80 so as to be inclined along the inclined surface 26a (FIG. 19).

  Therefore, the air for air conditioning A <b> 1 can be guided to the first fin 50 by being along the second fin 54. Thereafter, the air-conditioning air A1 is caused to flow along the first fin 50, thereby changing the direction to the direction orthogonal to the inclined surface 26a or the direction intersecting with the orthogonal direction, and blown obliquely downward from the air outlet 22. Can be made.

(5) The 3rd fin 58 is arrange | positioned in the intermediate part of the downstream end of the 1st fin 50, and the upstream end of the 2nd fin 54 (FIG. 8).
Therefore, the flow path of the air for air conditioning A1 can be suitably formed between the second fin 54 and the third fin 58 and between the third fin 58 and the first fin 50. In this way, a flow path of the air for air conditioning A1 can be suitably formed between the three fins 50, 54, and 58.

Moreover, when the operation member 65 is operated and the three fins 50, 54, 58 are tilted, the shape of the flow path between the three fins 50, 54, 58 can be suitably changed.
(6) The operation member 65 that is operated when the first to third fins 50, 54, and 58 are tilted and the operation member 65 that is operated when the plurality of upstream fins 62 are tilted by a common member. It is configured.

  Therefore, the number of parts can be reduced. Further, the space required for disposing the operation member 65 can be reduced. This point is effective in further reducing the thickness of the air conditioning thin register.

In addition, the said embodiment can also be implemented as a modification which changed this as follows.
