Description

The present invention relates to a register device for blowing air from an air conditioner into a vehicle interior in a vehicle.

A register device installed on an instrument panel or the like of a vehicle has a register body having a ventilation path and a fin assembly arranged in the ventilation path.
The fin assembly includes a plurality of fins arranged so as to cross the ventilation path and having a rotation axis extending in a direction intersecting the arrangement direction, and an interlocking mechanism for interlocking the plurality of fins. In a normal fin assembly, as the central fin rotates, the fins on both sides of the central fin rotate in the same direction as the central fin via an interlocking mechanism.

For example, in a thin register device, in a fin assembly facing an air outlet of a ventilation passage, the number of fins is often limited to three, a central fin and a pair of end fins on both sides thereof. When trying to rotate the pair of end fins in the same direction as the center fin, in order to avoid interference with the main wall facing the flat direction of the register device, the rotation axis of the pair of end fins is set from the main wall. It is necessary to separate them, but if this is done, it will not be possible to secure a sufficient distance between the intermediate fins and the end fins.
Therefore, various measures have been taken regarding the arrangement of the pair of end fins and the method of interlocking with the center fins.

In the fin assembly of the register device of Patent Document 1, each end fin has an upstream fin portion and a downstream fin portion, and the downstream end portion of the upstream fin portion and the upstream end portion of the downstream fin portion are common. It is connected on the rotation axis of. This rotation axis is near the main wall and does not move. The upstream fin portion of the pair of end fins is connected to the upstream end portion of the central fin via an interlocking link with an elongated hole, and the downstream fin portion is the downstream end portion of the central fin and the other with an elongated hole. It is connected via the interlocking link of.

In the fin assembly of Patent Document 1, when the central fin is in the basic posture parallel to the main wall, the upstream fin portion and the downstream fin portion of the pair of end fins are parallel to the central fin along the main wall. , Air blows out in front of the register device.
When the central fin is in an inclined posture, at the end fin closer to the downstream end of the central fin, the upstream fin portion is tilted in the same direction as the central fin, and the downstream fin portion is maintained in the posture along the main wall. At the end fin farther from the downstream end of the central fin, the upstream fin portion maintains the posture along the main wall, and the downstream fin portion tilts in the same direction as the central fin. As a result, air is blown out in the direction of inclination of the central fin.

In the fin assembly of the register device of Patent Document 2, the downstream end of the central fin is rotatably supported. Each end fin has an upstream fin portion and a downstream fin portion, and the downstream end portion of the upstream fin portion and the upstream end portion of the downstream fin portion are rotatably connected to each other. The axis is movable. The upstream end of the upstream fin portion is movable and rotatable along the ventilation path in the vicinity of the main wall. The downstream end of the downstream fin portion is rotatable at a position separated from the extension surface of the main wall. The upstream end of the downstream fin portion of the pair of end fins (the connecting portion of the upstream fin portion and the downstream fin portion) and the upstream end portion of the central fin are rotatably connected to the interlocking link.

In the fin assembly of Patent Document 2, the downstream fin portion of the pair of end fins is always parallel to the central fin. When the center fin is in the basic posture parallel to the main wall, the downstream fin portions of the pair of end fins are also parallel to the main wall, and the front blowout is executed. When the central fin is in the inclined posture, the downstream fin portions of the pair of end fins are also inclined in the same direction, and air can be blown out in the direction in which the central fin is directed. The upstream fins of the pair of end fins provide a smooth air flow from the main wall to the downstream fins.

In the register device of Patent Document 1, when the central fin is in an inclined posture, the air flowing between the central fin and the downstream fin portion of the end fin farther from the downstream end portion of the central fin is in the inclined direction of the central fin. Although it blows out, the air flow blown out from between the central fin and the downstream end of the end fin closer to the downstream end of the central fin intersects with this air flow, so the air blows out in the adjusted direction. Cannot be done well. Further, when the central fin is in the inclined posture, the upstream fin portion of one end fin is inclined, which hinders the smooth flow of air to the air outlet.

In the register device of Patent Document 2, the rotation axis of the downstream fin portion of the pair of end fins is separated from the extension surface of the main wall and approaches the central fin, which reduces the blowout area. Further, when the central fin is inclined and blows out in a direction away from the front, the directivity in the blowout direction may be too strong and the occupant may feel uncomfortable.

The present invention has been made to solve the above problems, and has a ventilation passage and a pair of main walls facing each other in the first direction across the ventilation passage, and the downstream end of the ventilation passage is from an air conditioner. In a vehicle register device provided with a register body provided as an air outlet for blowing out the air from the above air conditioner and a fin assembly facing the air outlet, the fin assembly is used.
A. An intermediate fin that is arranged in the middle portion of the ventilation path in the first direction and is rotatably supported by the register body about a rotation axis extending in a second direction orthogonal to the first direction.
I. A pair of end fins arranged in the vicinity of the pair of main walls on both sides of the intermediate fin in the first direction,
C. It is equipped with an interlocking mechanism that interlocks the intermediate fins and the pair of end fins.
Each of the end fins has an upstream fin portion and a downstream fin portion, and the downstream end portion of the upstream fin portion and the upstream end portion of the downstream fin portion extend in the second direction. One of the upstream end portion of the upstream fin portion and the downstream end portion of the downstream fin portion is rotatably connected about the axis, and is centered on the rotation axis extending in the second direction in the vicinity of the main wall. It is rotatably supported by the register body, and the other is rotatable around the rotation axis extending along the ventilation path and extending in the second direction in the vicinity of the main wall and supported by the register body. In the interlocking mechanism, the connecting portion of the upstream fin portion and the downstream fin portion of the pair of end fins is brought closer to or separated from the main wall as the intermediate fin rotates. When the intermediate fins are in the basic posture parallel to the main wall, the pair of end fins are in the same posture, and when the intermediate fins are in the inclined posture, the intermediate fins are moved. The downstream fin portion of the end fin closer to the downstream end portion is inclined in the same direction as the intermediate fin, and the downstream fin portion of the end fin farther from the downstream end portion of the intermediate fin is the downstream fin portion. It is characterized in that the distance between the above-mentioned intermediate fin and the intermediate fin is expanded in the blowing direction.

According to the above configuration, since the upstream end portion of the upstream fin portion and the downstream end portion of the downstream fin portion of the pair of end fins are always arranged near the main wall, a smooth flow of air flowing through the ventilation path Does not interfere with. Since the downstream end of the downstream fin portion is arranged near the main wall, the area of the air outlet of the ventilation path is not reduced.
When the intermediate fin is in the inclined posture, the downstream fin portion of the end fin closer to the downstream end portion of the intermediate fin is inclined in the same direction, so that air can be surely blown out along the inclination of the intermediate fin. At this time, the air flowing between the downstream end of the end fin farther from the downstream end of the intermediate fin and the intermediate fin is blown out while diffusing, so that the directivity of the air flow in the inclined direction is relaxed. Can be done.

As one aspect, the interlocking mechanism includes a connector movably supported by the register body along the ventilation path, a main link, and a pair of sub-links, and the main link is on the upstream side of the connector. At the same time, both ends thereof are rotatably connected to the upstream end of the intermediate fin and the upstream end of the connector, respectively, and the rotation of the intermediate fin is caused by the main link to cause the ventilation of the connector. Converted to movement along the road, one end of the pair of sub-links is rotatably connected to both sides of the first direction at the downstream end of the connector, and the other end of the pair of sub-links. The portions are rotatably connected to the connecting portions of the pair of end fins, respectively, and the movement of the connector is caused by the pair of sub-links so that the connecting portion of the pair of end fins approaches the main wall. -Converted to movement in the separation direction.
According to the above configuration, the interlocking mechanism can have a relatively simple configuration without using a cam mechanism. Further, the pair of end fins can take a substantially mirror-symmetrical posture.

In one aspect, when the intermediate fins are in the basic posture, the upstream fin portion and the downstream fin portion of the pair of end fins are in a posture parallel to the intermediate fins along the main wall, and the intermediate fins are in a parallel posture. When in the inclined posture, the connecting portion of the pair of end fins is separated from the main wall, and the upstream fin portion and the downstream fin portion are bent in a dogleg shape.
According to the above configuration, the distribution resistance can be minimized when the intermediate fin is in the basic posture and the front blowout is performed. Further, when the intermediate fin is in an inclined posture, the downstream fin portion of the end fin farther from the downstream end portion of the intermediate fin is inclined in a direction different from that of the intermediate fin, so that between the downstream fin portion and the intermediate fin. The air passing through can be diffused at a wider angle.

As another aspect, the interlocking mechanism includes an interlocking link extending in the first direction, and an intermediate portion of the interlocking link can be rotated to a portion of the intermediate fin that is separated from the rotation axis of the intermediate fin to the upstream side. Both ends of the interlocking link are rotatably connected to the connecting portion of the pair of end fins, respectively, and when the intermediate fin is in the basic posture, the connecting portion of the pair of end fins. Is away from the main wall, the upstream fin portion and the downstream fin portion are bent in a dogleg shape, and when the intermediate fin is in the inclined posture, the end fin closer to the downstream end of the intermediate fin. The connecting portion is farther from the main wall than when the intermediate fin is in the basic posture, and the connecting portion of the end fin farther from the downstream end portion of the intermediate fin is when the intermediate fin is in the basic posture. Get closer to the main wall.
According to the above configuration, the configuration of the interlocking mechanism can be simplified. Further, when the intermediate fins are in the basic posture of the front blowout, the downstream fin portions of the pair of end fins spread out from each other in the blowout direction, so that diffusion air can be blown.

In the other aspect, when the intermediate fin is in the inclined posture, the upstream fin portion and the downstream fin portion of the end fin far from the downstream end portion of the intermediate fin are in the posture along the main wall. ..
According to the above configuration, it is effective when it is desired to secure a sufficient air flow between the end fins farther from the downstream end portion of the intermediate fins and the intermediate fins.

Preferably, the register body is flattened in the first direction, and the intermediate fin is arranged at the center of the ventilation path in the first direction.

According to the present invention, the area of the air outlet of the ventilation passage is not reduced, the air can flow smoothly in the ventilation passage, the air can be surely blown out in the inclination direction of the intermediate fin, and the inclination direction. The directivity of the air flow can be relaxed.

The fins 21 are parallel to each other and rotate in the same direction by the interlocking link while maintaining the parallelism.

The downstream fin assembly 30 faces the air outlet of the ventilation passage 15 and adjusts the wind direction in the left-right direction. The downstream fin assembly 30 includes a central fin 31 (intermediate fin) and a pair of end fins 32 and 33, and the central fin. It is provided with an interlocking mechanism 40 that interlocks the 31 and the end fins 32 and 33.

The central fin 31 has an elongated flat plate shape extending in the vertical direction and is arranged substantially in the center of the ventilation passage 15 in the horizontal direction, and the upper and lower ends thereof are rotatably supported by the upper wall 13 and the lower wall 14 by the pin 34. ing. The rotation axis extending in the vertical direction of the central fin 31 is biased to the downstream side from the center in the width direction.

The pair of end fins 32 and 33 are arranged in the vicinity of the side walls 11 and 12 on both the left and right sides of the central fin 31 in the left-right direction. The pair of end walls 32 and 33 are divided into upstream fin portions 32a and 33a extending in the vertical direction and forming a flat plate shape and downstream fin portions 32b and 33b, respectively.
The downstream ends of the upstream fins 32a and 33a and the upstream ends of the downstream fins 32b and 33b are rotatably connected to each other by a pin 35 about a rotation axis extending in the vertical direction. This connecting portion is indicated by reference numeral P in FIGS. 3 to 5.

The central fin 31 is wider than the upstream fin portions 32a, 33a and the downstream fin portions 32b, 33b, and has substantially the same width as the straight end fins 32, 33, and these end fins 32, 33. It protrudes more in the blowing direction.

The downstream ends of the left and right downstream fin portions 32b and 33b can be rotated around the vertically extending rotation axis by the upper and lower pins 36 in the vicinity of the side walls 11 and 12 of the air outlet of the ventilation passage 15. It is connected.
The upstream ends of the left and right upstream fin portions 32a and 33a are moved up and down in the vicinity of the side walls 11 and 12 by inserting the pins 37 provided at the lower ends into the elongated holes 10x extending in the front-rear direction of the lower wall 14. It is supported so as to be rotatable about an extending rotation axis and movable in the front-rear direction (direction along the ventilation path 15).

The interlocking mechanism 40 of the present embodiment is mounted on the upper wall 13 of the register body 10, and includes a flat plate-shaped connector 41 and three links 42 to 44.
The connector 41 has an elongated rectangular shape in the front-rear direction, and is supported on the upper surface of the upper wall 13 of the register body 10 so as to be slidable in the front-rear direction. As shown in FIG. 1, a pair of left and right guide claws 18 are formed on the upper wall 13, and these guide claws 18 guide the connector 41 in the sliding direction. A pin 46, which will be described later, is projected from the upstream end of the connector 41, and two pins 47 are projected from the downstream end, and these pins 46 and 47 are formed on the upper wall 13. It is also guided in the sliding direction by being inserted into the elongated holes 10y and 10z extending in the front-rear direction (the elongated holes 10y are shown in FIGS. 2 to 5 and the elongated holes 10z are shown only in FIG. 1). It has become.

The three links 42 to 44 are arranged along the lower surface of the upper wall 13. The central main link 42 is arranged on the upstream side of the central fin 31, one end thereof is rotatably connected to the upstream end portion of the central fin 31 via a pin 45, and the other end portion is upstream of the connector 41. At the end, it is rotatably connected to the center in the left-right width direction via a pin 46.
When the central fin 31 rotates, the rotation is converted into the movement of the connector 41 in the front-rear direction via the main link 42.

One end of the left sub-link 43 is rotatably connected to the left side of the downstream end of the connector 41 via a pin 47, and the other end is a connecting portion P of the left end fin 32, more specifically. Specifically, it is rotatably connected to the downstream end of the upstream fin portion 32a via a pin 48.
One end of the right sub-link 44 is rotatably connected to the right side of the downstream end of the connector 41 via a pin 47, and the other end is a connecting portion P of the right end fin 33, more specifically. Specifically, it is rotatably connected to the downstream end of the upstream fin portion 32a via a pin 48.
In each of the end fins 32 and 33, the pin 48 and the pin 35 are preferably arranged on the same rotation axis.

As shown in FIG. 1, an operation knob 50 is slidably supported in the vertical direction on the central fin 31, and the operation knob 50 is gripped to rotate the central fin 31 around a rotation axis extending in the vertical direction. By passing it, the blowing direction can be adjusted to the left or right.

The operation knob 50 is provided with an engaging member 51 that projects toward the back, and the engaging member 51 is engaged with fins 21 located near the center in the vertical direction in the back fin assembly 20. .. When the operation knob 50 is slid vertically along the central fin 31, the plurality of back fins 21 rotate around the rotation axis extending in the left-right direction, whereby the blowing direction can be adjusted up and down. it can.

Next, left and right adjustment of the blowing direction by the blowing side fin assembly 30 of the register device will be described.
As shown in FIG. 3, when the central fin 31 is in the basic posture parallel to the left and right side walls 11 and 12, the main link 42 is located on the same plane as the central fin 31 and is parallel to the side walls 11 and 12. The left and right links 43 and 44 are greatly inclined with respect to the side wall 11. The connecting portions P of the end fins 32 and 33 are located close to the side walls 11 and 12, and the upstream fin portions 32a and 33a and the downstream fin portions 32b and 33b are arranged along the side walls 11 and 12, and the end fins 32 , 33 are in a straight state. The air flowing from the upstream side of the ventilation passage 15 flows straight along the central fins 31 and the end fins 32 and 33 with almost no resistance from the end fins 32 and 33, and blows out from the front of the register device.

As shown in FIG. 4, when the operation knob 50 is grasped and the central fin 31 is rotated so that the downstream end thereof moves to the right, that is, in the counterclockwise direction in FIG. 4, the central fin 31 is rotated via the main link 42. The connector 41 moves in the blowing direction, and accordingly, the connecting portion P of the end fins 32, 33 moves away from the side walls 11 and 12 via the left and right links 43 and 44, and as a result, the end The upstream fin portions 32a and 33a and the downstream fin portions 32b and 33b rotate so that the fins 32 and 33 form an inwardly convex dogleg shape. This rotation is possible by moving the upstream ends of the upstream fin portions 32a and 33a in the blowing direction. The pair of end fins 32 and 33 are mirror-symmetrical and their postures change.

By the above operation, the downstream fin portion 33b of the right end fin 33 (the end fin 33 closer to the downstream end of the central fin 31) is tilted in the same direction as the central fin 31 and becomes substantially parallel to the upstream of the ventilation path 15. The main portion of the air from the side is blown to the right along the central fin 31 and the downstream fin portion 33b. This air flow can be reliably blown to the right without being disturbed by other air flows described later.

A part of the air from the upstream side of the ventilation passage 15 passes through the central fin 31 and the upstream fin portion 32a of the left end fin 32 (the end fin 32 far from the downstream end of the central fin 31), and further in the center. It blows out through the fin 31 and the downstream fin portion 32b. Since the downstream fin portion 32b is tilted in a direction different from that of the central fin 31 and the distance between them is widened toward the blowing direction, this air is diffused so as to spread along the central fin 31 and the downstream fin portion 32b. And blow it out. Therefore, the directivity of the air flow blown to the right can be relaxed.

As described above, when the central fin 31 is in the inclined posture, the end fins 32 and 33 have a dogleg shape, so that the air flowing along the side walls 11 and 12 is the upstream fin portion 32a of the end fins 32 and 33. , 33 smoothly flows to the downstream fin portions 32b, 33b.

As shown in FIG. 5, when the central fin 31 is rotated so that its downstream end moves to the left, that is, in the clockwise direction in FIG. 5, the connecting portion P of the end fins 32 and 33 becomes the side wall 11, Moving away from 12, the end fins 32 and 33 form an inwardly convex dogleg. Since the operation is the same as the above, briefly explaining, the downstream fin portion 32b of the left end fin 32 (the end fin 32 closer to the downstream end of the central fin 31) is tilted in the same direction as the central fin 31. The downstream fin portion 33b of the right end fin 33 (the end fin 33 far from the downstream end of the central fin 31) is tilted in a direction different from that of the central fin 31. As a result, it is possible to perform a blowout to the left and a diffusion blowout to the right.

Next, the register device according to the second embodiment of the present invention will be described with reference to FIGS. 6 and 7. In these figures, the components corresponding to the first embodiment are designated by the same numbers and detailed description thereof will be omitted.

The interlocking mechanism comprises one interlocking link 60. The interlocking link 60 has a dogleg shape and extends in the left-right direction along the lower surface of the upper wall 13 of the register body 10. The bent portion at the center of the interlocking link 60 is rotatably connected to the center of the central fin 31 in the width direction (upstream from the pin 34 which is the rotation axis) by the pin 61. The left end of the interlocking link 60 is rotatably connected to the connecting portion P of the left end fin 32, specifically, the downstream end of the upstream fin portion 32a via a pin 62, and the right end of the interlocking link 60 is It is rotatably connected to the connecting portion P of the right end fin 33, specifically, the downstream end portion of the upstream fin portion 33a via a pin 62.

As shown in FIG. 7A, when the central fin 31 is in the basic posture parallel to the side walls 11 and 12, the connecting portion P of the pair of end fins 32 and 33 is separated from the side walls 11 and 12, and the end fins. 32 and 33 have the same posture with an inwardly convex dogleg shape. In the front blowout, since the downstream fin portions 32b, 33b of the pair of end fins 32, 33 are arranged so as to widen the distance from each other in the blowout direction, they can be diffused and blown out.

As shown in FIG. 7B, when the central fin 31 is rotated so that its downstream end moves to the right, that is, counterclockwise, the interlocking link 60 moves to the left. As a result, the connecting portion P of the right end fin 33 is further separated from the side wall 12, the bending angle of the dogleg shape is increased, and the downstream fin portion 33b is tilted in the same direction as the central fin 31 and substantially in parallel. On the other hand, the connecting portion P of the left end fin 32 approaches the side wall 11, and the bent state of the dogleg shape is eliminated to become a straight state along the side wall 11.
In the state where the central fin 31 is tilted to the right as shown in FIG. 7B, the blowout to the right is executed and the diffusion blowout is executed on the left side, as in the first embodiment. Since the left end fin 32 is arranged along the side wall 11, the flow resistance on the left side is smaller than that in the first embodiment.

As shown in FIG. 7C, when the central fin 31 is rotated so that its downstream end moves to the left, that is, clockwise, the interlocking link 60 moves to the right. As a result, the connecting portion P of the left end fin 32 is further separated from the side wall 11, the bending angle of the dogleg shape is increased, and the downstream fin portion 32b is tilted in the same direction as the central fin 31 and substantially in parallel. On the other hand, the connecting portion P of the right end fin 33 approaches the side wall 12, and the bent state of the dogleg shape is eliminated to become a straight state along the side wall 11. Since other operations are the same as those in FIG. 7B, the description thereof will be omitted.

The present invention is not limited to the above embodiment, and various aspects are possible.
For example, the upstream end portion of the upstream fin portion of the end fin may be rotatably supported, and the downstream end portion of the downstream fin portion may be rotatably supported in the front-rear direction.
The sub-links 32, 33 of the first embodiment and the interlocking link 60 of the second embodiment were connected to the downstream end portions of the upstream fin portions 32a, 33a as the connecting portions P of the end fins 32, 33, but on the downstream side. It may be connected to the upstream end portion of the fin portions 32b and 33b.
In the first embodiment, when the central fin 31 is in the basic posture, the end fins are in a straight posture along the side wall, but an inwardly convex dogleg shape may be used. In this case, even in the first embodiment, if it is diffused, front blowout can be performed.

In the above embodiment, the thin register device is installed horizontally, but it may be installed vertically. In this case, the center fin and the end fin are arranged in the vertical direction (first direction), and the rotation axis thereof extends in the horizontal direction (second direction).
The present invention is also applicable to a register device that is not thin. In this case, a plurality of intermediate fins can be arranged.

The present invention can be applied to a register device for air conditioning of a vehicle.
