Description

Technical Field

[0001] The present invention relates to a wind direction adjusting body and a wind direction adjusting device. The wind direction adjusting body changes the wind direction by rotation, and the wind direction adjusting device includes the wind direction adjusting body. Background Art

[0002] Conventionally, in an air conditioning device used in a vehicle such as an automobile, there is a wind direction adjusting device for adjusting the wind direction of the blown air. In the wind direction adjusting device, louvers for adjusting the wind direction are rotatably arranged. Among such louvers, there is known a louver formed by assembling a plurality of divided louver members to each other (for example, refer to Patent Document 1).

[0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2005-121306 (pages 4-6, Figure 1 -7)

[0004] In the case of a structure in which a plurality of louver members are assembled to each other, the center of gravity of the louver deviates due to design errors or assembly errors of the louver members. In particular, in the case of a louver having rotation shafts on both the left and right sides and rotating it up and down, if the center of gravity of the louver is far from the rotation axis, the operating force will vary greatly depending on the rotation direction due to the own weight of the louver, which causes deterioration of the operating feeling. Summary of the Invention

[0005] The present invention has been made in view of such circumstances, and an object thereof is to provide a wind direction adjusting body and a wind direction adjusting device capable of improving the operating feeling.

[0013] Advantages of the Invention

[0014] According to the wind direction adjusting body described in [1], the position of the center of gravity can be made close to the rotation axis by the center of gravity setting portion, so that it is possible to suppress the load difference of the operating force generated in the up-and-down rotation direction due to its own weight, and improve the operating feeling.

[0015] According to the wind direction adjusting body described in [2], in addition to the effects of the wind direction adjusting body described in [1], it is also possible to prevent the influence of the center of gravity setting portion on the flow rectifying effect of the surface of the louver, and ensure the air distribution performance.

[0016] According to the wind direction adjusting body described in [3], in addition to the effects of the wind direction adjusting body described in [1], it is also possible to easily set the center of gravity setting portion into a desired shape.

[0017] According to the wind direction adjusting body described in [4], in addition to the effects of the wind direction adjusting body described in [3], there is also the following effect: even if a load is further applied in the direction of rotating the louver from the position of the rotation limit of the louver based on the stopper portion, the load is not easily a force that acts to separate the fixed structure of the component, thereby suppressing the splitting of the component.

Detailed description of the embodiments

[0027] Hereinafter, with reference to the accompanying drawings, the first embodiment of the present invention will be described.

[0028] In Figure 3 1 is a wind direction adjusting device. The wind direction adjusting device 1 is also referred to as an air outlet, a ventilation device, an air conditioner, etc., and adjusts the blowing direction of the air from an air conditioner or the like. Hereinafter, for the sake of clarity, in the wind direction adjusting device 1, the lower side of the wind where the wind blows out is defined as the front side, the front face side, or the near side, and the opposite side, i.e., the upper side of the wind where the wind is received, is defined as the rear side, the back side, or the inside. When observing from the front side, the two side directions or the width direction and the up-down direction are defined as the left and right directions. In the present embodiment, the wind direction adjusting device 1 is applicable to an air conditioner for a vehicle such as an automobile. The wind direction adjusting device 1 can be arranged at any position, but in the accompanying drawings, it is arranged such that the arrow FR side is the front side, the arrow RR side is the rear side, the arrow L side is the left side, the arrow R side is the right side, the arrow U side is the upper side, and the arrow D side is the lower side. These directions are merely illustrated as an example and can be appropriately changed according to the installation position or the installation orientation of the wind direction adjusting device 1.

[0029] The wind direction adjusting device 1 includes a housing 2. An air passage 3 for the air-conditioning air as a fluid to flow is formed inside the housing 2. The air-conditioning air passes through the air passage 3 in the front-rear direction as a prescribed first direction. That is, inside the air passage 3, the rear side is the upstream side of the ventilation direction, and the front side is the downstream side of the ventilation direction. And, on the housing 2, an air receiving port for receiving the air-conditioning air is formed in the air passage 3. The air receiving port is located at the rear end which is the upstream end of the air passage 3. Moreover, on the housing 2, an air outlet 5 through which the air-conditioning air passing through the air passage 3 blows out is formed. The air outlet 5 is located at the front end which is the downstream end of the air passage 3. The air outlet 5 communicates with the vehicle interior and is arranged to blow the air-conditioning air into the vehicle interior.

[0030] In the present embodiment, the housing 2 is formed in a corner tube shape. The housing 2 has a prescribed length in the ventilation direction of the air passage 3. The housing 2 is composed of one or more components.

[0031] Further, a louver 10 serving as an air distribution part, i.e., a wind direction adjusting body, is installed on the housing 2. The louver 10 is an air distribution component also known as a fin or the like. The louver 10 is a horizontal fin that distributes air in the vertical direction by rotating in the vertical direction about an axis in the left-right direction. As an example, the louver 10 rotates according to the operation of an operation part 11 such as an operation knob. In the present embodiment, the operation part 11 is installed on the louver 10 and is configured to be directly manually operated by a user such as a vehicle occupant.

[0032] The louver 10 includes a louver main body part 12. The louver main body part 12 is formed in a long strip shape. The louver main body part 12 is arranged in the air passage 3 of the housing 2 such that the thickness direction becomes the up-down direction. That is, the louver main body part 12 is formed in a plate shape, and this plate shape has a first rectifying surface 12a as one main surface that is a planar shape parallel to each other and a second rectifying surface 12b as the other main surface. Therefore, the louver main body part 12 is formed in a flat shape along the thickness direction. The first rectifying surface 12a and the second rectifying surface 12b are respectively arranged to extend in a long strip shape in the left-right direction.

[0033] In the present embodiment, a rotating shaft 13 is formed on the louver main body part 12. The rotating shaft 13 is located at both end parts in the length direction of the louver main body part 12. The rotating shaft 13 is formed in a cylindrical shape. The rotating shaft 13 protrudes from the louver main body part 12 and is rotatably supported by the housing 2. That is, in the present embodiment, the rotating shaft 13 is located on the left and right side parts of the louver 10 in a state of being supported by the housing 2.

[0034] Further, in the present embodiment, the rotating shaft 13 and the rotation axis line A serving as its central axis are located at a position closer to the downstream side of the wind passing through the air passage 3 in the louver 10. That is, the rotating shaft 13 and the rotation axis line A are located at a position closer to the front side among both end parts of the louver main body part 12. In the illustrated example, the rotating shaft 13 and the rotation axis line A are located more forward than the central part in the front-rear direction of the first rectifying surface 12a and the second rectifying surface 12b. Further, the rotating shaft 13 and the rotation axis line A are located more rearward than the front end parts of the first rectifying surface 12a and the second rectifying surface 12b. Moreover, the rotating shaft 13 and the rotation axis line A are located at the central part in the thickness direction of the louver main body part 12.

[0035] Moreover, a connecting portion 15 for connecting the louver 10 to other air distribution bodies is formed on the louver 10. The connecting portion 15 is a part that enables the rotation of other air distribution bodies to be linked with that of the louver 10. In the louver 10, the connecting portion 15 is set to be parallel to the rotation axis 13 (rotation axis line A). For example, at one end portion of the louver main body portion 12, the connecting portion 15 is located at a position away from the rotation axis 13 of the louver 10. In the present embodiment, the connecting portion 15 is separated in the width direction of the louver main body portion 12, i.e., the front-rear direction, and is located behind the rotation axis 13. The connecting portion 15 is formed in a cylindrical shape. A connecting rod 16 is connected to the connecting portion 15. The connecting rod 16 has a plurality of support holes 17 for rotatably supporting the connecting portion 15 or other air distribution bodies. In the present embodiment, there are 3 support holes 17. The movement limit of the connecting rod 16 is set by abutting against a stopper portion 18. In the present embodiment, the stopper portion 18 is set below the connecting rod 16. The stopper portion 18 is formed on the housing 2, for example.

[0036] And, as Figure 1 shown, a center-of-gravity setting portion 20 for setting the position of the center of gravity G is formed on the louver 10. Specifically, the center-of-gravity setting portion 20 controls the center-of-gravity distribution of the louver 10 by setting the distance between the center of gravity G of the louver 10 and the rotation axis line A. The center-of-gravity setting portion 20 is located at a position buried inside the louver main body portion 12. The center-of-gravity setting portion 20 is constituted by using a part of the structure of the louver 10.

[0037] In the present embodiment, the center-of-gravity setting portion 20 is disposed in a hollow portion 21 formed inside the louver 10. The hollow portion 21 is formed along the length direction of the louver 10. And, in the hollow portion 21, the rotation axis line A passes through a position near the front end portion of the hollow portion 21 having a prescribed length in the front-rear direction. In addition, the hollow portion 21 may be a structure that is entirely located inside the louver main body portion 12, or may be a structure formed in such a manner that a part thereof is exposed to the outside of the louver main body portion 12, i.e., in a manner communicating with the outside of the louver main body portion 12.

[0038] In the illustrated example, by dividing the louver 10 into a plurality of components 23, the hollow portion 21 is formed inside the louver 10. That is, the louver 10 of the present embodiment is a split type constituted by assembling a plurality of components 23. In the illustrated example, one component 25 and another component 26 are set on the component 23. By fixing the one component 25 and the another component 26 to each other, the louver 10 is formed as a single body.

[0039] One component 25 is a component mainly constituting one airfoil surface 12a side and the front end portion side of the louver main body portion 12. One component 25 is formed of, for example, glass fiber-reinforced PBT resin or the like. As Figure 1 and Figure 2As shown in (a), a component 25 has a component main body portion 28. The component main body portion 28 is formed as a flat plate in a long strip shape, and one main surface serves as a fairing surface 12a. The other main surface of the component main body portion 28 serves as a wall portion of a hollow portion 21. A component end wall portion 29 is connected and formed on the component main body portion 28. The component end wall portion 29 is connected across the entire end portion in the width direction of the component main body portion 28 and is folded back in a U shape in the cross-sectional view. Therefore, a receiving portion 30 is formed on the back side of the component end wall portion 29. And, a locking portion 31 as a fixing portion is formed on the component main body portion 28. The locking portion 31 is formed at the other end portion in the width direction of the component main body portion 28. The locking portion 31 may be formed across the entire length direction of the component main body portion 28, may be formed on a part of the length direction, or may be formed intermittently at multiple locations in the length direction. In the present embodiment, the locking portion 31 is formed to project in a claw shape as a part of the thickness direction of the component main body portion 28.

[0040] And, side wall portions 32 are connected and formed at the end portions in the length direction of the component main body portion 28 and the component end wall portion 29. The side wall portions 32 constitute the end portions in the length direction of the louver main body portion 12. In the present embodiment, a rotation shaft 13 is formed on the side wall portions 32.

[0041] And, when the louver 10 is installed in the housing 2( Figure 3 ), the component 25 is arranged such that the length direction of the component main body portion 28 and the component end wall portion 29 is the left-right direction, one main surface of the component main body portion 28 is the upper side, and the component end wall portion 29 is the front side.

[0042] Another component 26 is a component mainly constituting the other fairing surface 12b side and the rear end portion side of the louver main body portion 12. The other component 26 is formed of the same or different material as the component 25. For example, the other component 26 is formed of polyacetal resin or the like. As Figure 1 and Figure 2 shown in (b), the other component 26 has another component main body portion 35.

[0043] The other component main body portion 35 is formed as a flat plate shape that is long and strip-shaped, and one main surface serves as the other wall portion of the hollow portion 21. The other main surface of the other component main body portion 35 serves as the other rectifying surface 12b. An insertion portion 36 is formed and connected to the other component main body portion 35. The insertion portion 36 is a portion that inserts into the receiving portion 30 of one component 25 and catches one end portion in the width direction of the other component 26 at one end portion in the width direction of one component 25. The insertion portion 36 is connected to one end portion in the width direction of the other component main body portion 35. The insertion portion 36 may be connected throughout the entire length direction of the other component main body portion 35, may be connected to a part of the length direction, or may be intermittently connected at multiple locations in the length direction. And, another component end wall portion 37 is formed and connected to the other component main body portion 35. The other component end wall portion 37 is connected to the other end portion in the width direction of the other component main body portion 35, that is, the end portion on the side opposite to the insertion portion 36, and protrudes more in the thickness direction than one main surface of the other component main body portion 35.

[0044] Another locking portion 38 as another fixing portion is formed on the other component end wall portion 37. The other locking portion 38 fixes one component 25 and the other component 26 together by engaging with one locking portion 31 of one component 25. In the present embodiment, the other locking portion 38 is formed in a claw shape that folds back from the other component end wall portion 37 to the side of the other component main body portion 35. Through the receiving portion 30, the insertion portion 36, one locking portion 31, and the other locking portion 38, a locking structure is constituted as a fixing structure for fixing one component 25 and the other component 26 together. By mutually locking one component 25 and the other component 26, the hollow portion 21 is partitioned between one component 25 and the other component 26. Additionally, it may be configured such that the receiving portion 30 is formed on the other component 26 and the insertion portion 36 is formed on one component 25.

[0045] And, in a state where the louver 10 is installed in the housing 2( Figure 3 )), the other component 26 is arranged such that the length direction of the other component main body portion 35 is the left - right direction, one main surface of the other component main body portion 35 is the upper side, and the other component end wall portion 37 is the rear side.

[0046] And, in the present embodiment, a connecting portion 15 is formed on the other component 26. In the illustrated example, the connecting portion 15 is arranged at one end portion in the length direction of the other component 26. For example, the connecting portion 15 is arranged at one end portion in the length direction of the other component main body portion 35 of the other component 26, or at one end portion in the length direction of the other component end wall portion 37. In the present embodiment, the connecting portion 15 is located below the other locking portion 38. That is, with respect to the fixing structure of one component 25 and the other component 26, the connecting portion 15 is arranged on the same side as the stopper portion 18( Figure 3 ).

[0047] Further, in the present embodiment, a center-of-gravity setting portion 20 is formed on another member 26. In the illustrated example, the center-of-gravity setting portion 20 is formed on one main surface side of another member main body portion 35 of another member 26. The center-of-gravity setting portion 20 can be formed arbitrarily. For example, it has a first portion 40 formed continuously or intermittently in the length direction, and a second portion 41 connected in a direction intersecting the first portion 40. The first portion 40 and the second portion 41 are each formed as ribs integrally molded from the same material as the another member main body portion 35. In the present embodiment, the second portion 41 is formed at multiple locations in the length direction of the first portion 40. And, when viewed from the direction of the rotation axis A, at least a part of the center-of-gravity setting portion 20, preferably all of it, is located within the projection of the rotation shaft 13. That is, at least a part of the center-of-gravity setting portion 20, preferably all of it, is located within the region where the outer peripheral surface of the rotation shaft 13 extends along the rotation axis A. And, it is configured such that the distance of the center of gravity G of the louver 10 from the rotation axis A is set according to the shape of the thickness and length of the first portion 40 and the second portion 41 including the center-of-gravity setting portion 20, the number of the second portions 41, and the position relative to the rotation axis A.

[0048] In addition, multiple louvers 10 can be arranged facing Figure 3 the illustrated air outlet 5. In this case, the multiple louvers 10 are preferably connected by a link 16 and linked to rotate in the same direction. And, on the housing 2, in addition to the louvers 10, any air distribution body or shut-off valve etc. can be movably installed.

[0049] And, as Figure 1 shown, when assembling the louver 10, the insertion portion 36 of another member 26 is inserted into the receiving portion 30 of one member 25 formed in advance respectively, so that another locking portion 38 of another member 26 is engaged with one locking portion 31 of one member 25, whereby the louver 10 in which one member 25 and another member 26 are fixed to each other integrally can be easily assembled ( Figure 2 in (c)).

[0050] In the assembled louver 10, the link 16 is connected to the connecting portion 15 as needed, and in a state where it can be linked with other air distribution bodies, it is assembled into the housing 2 in such a manner that the rotation shaft 13 is rotatably supported on the housing 2 side, and is arranged to rotate in the vertical direction. The user grasps the operation portion 11 installed on the louver 10 and performs an up-and-down operation, thereby causing the louver 10 to rotate up and down.

[0051] At this time, the farther the center of gravity G of the louver 10 rotating in the vertical direction is from the rotation axis A, the greater the vector of the louver 10 rotating downward due to its own weight. When rotating in the direction of this vector, the load is relatively small, and when rotating in the opposite direction, the load is relatively large. Therefore, in the first embodiment, by providing the center of gravity setting unit 20 that sets the distance between the center of gravity G and the rotation axis A, the position of the center of gravity G can be made closer to the rotation axis A by the center of gravity setting unit 20, thereby suppressing the load difference of the operating force generated in the vertical rotation direction due to its own weight as described above and improving the operating feeling. In the case of this embodiment, by making the center of gravity G closer to the rotation axis A, the load of the louver 10 rotating downward at the rear part, which is the upstream side of the louver 10, due to its own weight can be suppressed. Therefore, no matter which direction, upward or downward, the louver 10 is rotated, it is not easy to generate a load difference due to its own weight, and thus the operating feeling can be improved.

[0052] By disposing the center of gravity setting unit 20 in the hollow portion 21 inside the louver 10, the influence of the center of gravity setting unit 20 on the air rectifying effect of the surface of the louver 10 (one air rectifying surface 12a and the other air rectifying surface 12b) can be prevented, thereby ensuring the air distribution performance of the louver 10.

[0053] By dividing the louver 10 into a plurality of components 23, the hollow portion 21 can be easily formed, and the center of gravity setting unit 20 can be easily set into a desired shape. Moreover, in the case of integrally forming the thickness of the louver 10, even when it cannot be dealt with under normal molding conditions, by dividing it into a plurality of components 23, each component 23 can be set to a thickness within the molding conditions and dealt with, so that appearance defects such as depressions caused by thick walls can be suppressed, and thus the appearance performance and the air distribution performance can be maintained.

[0054] On the other hand, even when the louver 10 is divided into a plurality of components 23, by forming the rotation shafts 13 at both ends of the louver 10 on any one of the components 23, compared with the case where the rotation shafts 13 are formed on different components 23 respectively, it is easier to obtain the accuracy of the rotation axis A. Each component 23 does not need to be formed with a higher accuracy than necessary, the component cost can be suppressed, and the assembly into the housing 2 is also easy, and the cost required for the assembly operation can be suppressed.

[0055] Furthermore, in the case of a structure in which the louver 10 is divided into a plurality of parts 23 opposed to each other in the up-down direction serving as the rotation direction, for example, when the louver 10 is rotated to its maximum position and the connecting rod 16 is assumed to be in contact with the stopper 18, if a user further applies a load by operating the operating portion 11, the position of the connecting rod 16 remains unchanged, but on the other hand, the load is applied from the operating portion 11 to the connecting portion 15 because the louver 10 is to be moved toward the connecting portion 15 connected to the connecting rod 16. Here, in the present embodiment, a connecting portion 15 is formed below the same side as the stop portion 18 relative to the fixing structure of one fixing portion 31 and another fixing portion 38, thereby, even if a load is applied in a direction of further rotating the louver 10 relative to the operating portion 11 from the position of the rotation limit of the louver 10 abutting against the stop portion 18 from the lower portion of the connecting rod 16, the load is unlikely to become a force acting on the fixing structure of the separation component 23 (one component 25 and another component 26), thereby being able to suppress the splitting of the component 23 (one component 25 and another component 26).

[0056] Furthermore, since the rotation axis A of the louver 10 is located downstream of the wind, the louver 10 can be rotated greatly with respect to the amount of operation in the vertical direction downstream of the louver 10 , thereby improving the air distribution performance of the louver 10 .

[0057] Furthermore, by providing the louver 10 in the wind direction adjusting device 1, it is possible to provide a wind direction adjusting device having excellent operability and air distribution performance.

[0058] In the first embodiment described above, one component 25 and another component 26 may be fixed to each other by welding (vibration welding) or the like. Figure 4 In the second embodiment shown in FIG. 1 , a welding portion 45 such as a welding pin can be formed as a fixing portion on another member 26, or as shown in FIG. Figure 5 In the third embodiment shown, the welding portion 45 is formed on one component 25. In any of these cases, the same effects as those of the first embodiment can be obtained, and the one component 25 and the other component 26 can be more firmly fixed to each other, so that even if a load is applied in a direction in which the louver 10 is further rotated relative to the operating portion 11 from the position of the rotation limit of the louver 10 where the link 16 abuts against the stopper 18, the louver 10 is not easily split by the load.

[0059] Furthermore, in each of the above-mentioned embodiments, the center-of-gravity setting portion 20 may be formed in one member 25. That is, the center-of-gravity setting portion 20 may be formed in at least one of the one member 25 and the other member 26.

[0060] The center of gravity setting portion 20 is not limited to adding weight to one component 25 and / or another component 26, and the weight may be reduced by removing thickness of one component 25 and / or another component 26, cutting off a portion, or forming a hole.

[0061] Furthermore, by setting the materials of the one member 25 and the other member 26 , the distance from the rotation axis A to the center of gravity G may be set according to the difference in their specific gravities.

[0062] Furthermore, the rotation axis 13 may be formed on the other member 26. That is, the rotation axis 13 may be formed on either the one member 25 or the other member 26.

[0063] The louver 10 does not need to include the rotation shaft 13 , and may be configured to be rotatably pivotally supported by a rotation shaft formed on the housing 2 .

[0064] Furthermore, the connecting portion 15 may be formed on one member 25 as long as it is set on the same side as the stopper portion 18 based on the fixing structure between the one member 25 and the other member 26 and based on the fixing structure.

[0065] Furthermore, the plurality of members 23 constituting the louver 10 are not limited to two members 25 and 26 , and may be three or more.

[0066] Furthermore, the center of gravity setting portion 20 may be configured by separately assembling a member having a different material with a different specific gravity from the one member 25 and the other member 26. In this case, the center of gravity setting portion 20 can be configured to be more compact by using a member with a large specific gravity.

[0067] Furthermore, the louver 10 is not limited to being directly rotated by the operation of the operation unit 11 attached to the louver 10, but may be rotated in conjunction with an operation of actuating other air distribution bodies.

[0068] Industrial Applicability

[0069] The present invention can be preferably used as a louver of an air direction adjusting device for a car air conditioner, for example.
