[0001] The present invention relates to an air direction adjusting device including fins arranged on a frame having an air outlet. Background Art

[0002] Conventionally, air conditioning devices used in vehicles such as automobiles have wind direction adjustment devices for adjusting the direction of blown wind. Wind direction adjustment devices are also called air conditioning wind blowing devices, air outlets, ventilators, air conditioning devices, etc., and are installed in various parts of the vehicle such as the dashboard or the center console, and help improve comfort performance through cooling and heating.

[0003] Japanese Patent Application Laid-Open No. 2007-76481 discloses an air direction adjusting device in which a surface of a trimmer having an air outlet and an end portion of a fin for adjusting the air direction on the vehicle compartment side are continuously visible. Summary of the invention

[0004] In the above structure, the shaft portion formed on one side of the fin is inserted into the shaft hole formed on one side wall of the shell, the shaft portion of the convex portion formed on the side wall of the shell is embedded in the shaft hole formed on the other side of the fin, and the convex portion is embedded in the space inside the protrusion formed at the edge of the blowing outlet of the trimmer.

[0005] However, in the case of the above-mentioned structure, since the engagement between the shaft portion of the shell and the axial hole of the fin, the engagement between the protrusion of the shell and the protrusion of the trimmer, and the dimensional relationship between the shaft portion of the fin and the axial hole of the shell require the mutual dimensional accuracy of the paired components, especially in the case of a fine shape with small dimensions in various places, even slight product deviations are easily affected, requiring complex adjustments, which may lead to increased product costs.

[0006] An object of the present invention is to provide an air direction adjusting device which is not easily affected by product variations and can be constructed with high precision.

[0007] The wind direction adjustment device involved in the embodiment comprises: a frame having a blow-out port; a fin for adjusting the wind direction; a fin support portion, which is located at the edge of the blow-out port of the frame and supports the fin; a recess formed in one of the fin support portion and the fin; an axis portion, which is formed in the other of the fin support portion and the fin and is accommodated in the recess; and a retaining portion, which is installed in the recess and retains the axis portion in the recess in a rotatable manner.

[0008] In the wind direction adjusting device according to the embodiment, the recessed portion may be formed in the fin supporting portion, and the shaft portion may be formed in the fin.

[0009] In the wind direction adjusting device according to the embodiment, the recessed portion may be formed on a rear surface side of the fin support portion.

[0010] In the wind direction adjusting device according to the embodiment, the holding portion may be fixed by welding.

[0011] In the air direction adjusting device according to the embodiment, the holding portion may be inserted into the recessed portion, and the holding portion may be fixed by locking in a direction intersecting a direction of insertion from the back side of the fin support portion toward the recessed portion.

[0012] In the wind direction adjusting device according to the embodiment, the fin support portion may protrude inward from an edge of the air outlet, and a front end portion of the fin support portion may be formed to be continuous with a front end portion of the fin in a protruding direction of the fin support portion.

[0013] According to the wind direction adjusting device having the above structure, since the position of the fin relative to the frame is determined only by the relationship between the recessed portion, the holding portion, and the shaft portion, it is not easily affected by product variations and can be configured with high precision.

[0014] According to the wind direction adjustment device with the above structure, there is no need to form the fixing structure of the retaining part on the fin, and unnecessary bumps and depressions that cause turbulence will not be formed on the guide surface of the fin. A larger recess can be obtained without increasing the thickness of the fin, and the retaining part can be easily installed without damaging the wind direction adjustment function of the fin.

[0015] According to the wind direction adjustment device with the above structure, when an object collides with the wind direction adjustment device, the shaft of the fin presses the retaining portion backward to cause the retaining portion to detach from the fin support portion, so that the fin can quickly detach from the frame in a direction away from the object, thereby reducing the impact on the colliding object.

[0016] According to the wind direction adjusting device having the above structure, the holding portion can be fixed more appropriately.

[0017] According to the wind direction adjusting device having the above configuration, the holding portion can be fixed simply by inserting the holding portion into the recessed portion, so that the holding portion can be easily fixed.

[0018] According to the wind direction adjusting device having the above structure, a linear preferred appearance that crosses the air outlet can be formed, and the appearance can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0028] exist Figure 6In the figure, 10 is a wind direction adjusting device. The wind direction adjusting device 10 is also called an air outlet, a ventilator, an air regulating device, etc., and is used to adjust the blowing direction of the wind from the air conditioning device, etc. In the following, in order to make the description clearer, for the wind direction adjusting device 10, the side of the wind blowing out, that is, the downwind side, is referred to as the front side, the front side or the front side (the arrow FR side in the accompanying drawings), and the opposite side, that is, the side receiving the wind, that is, the upwind side, is referred to as the rear side, the back side or the back side (the arrow RR side in the accompanying drawings). The direction parallel to the arrow FR and the arrow RR is referred to as the front-to-back direction, the two side directions or the width direction when viewed from the front side is referred to as the left-to-right direction (the arrow L side in the accompanying drawings is referred to as the left side, and the arrow R side is referred to as the right side), and the direction orthogonal to the front-to-back direction and the left-to-right direction is referred to as the up-down direction (the arrow U side in the accompanying drawings is referred to as the upper side, and the arrow D side is referred to as the lower side). In the present embodiment, the wind direction adjusting device 10 is applied to an air conditioning device for vehicles such as automobiles. The wind direction adjusting device 10 can be arranged at any position, but in the drawings, 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 shown as an example, and may be appropriately changed depending on the installation position and installation direction of the wind direction adjusting device 10.

[0029] The wind direction adjusting device 10 includes a casing 14 of a duct portion as a structural member, a trimmer 15 as a frame body attached to the casing 14 , and fins 16 for wind direction adjustment attached to the trimmer 15 .

[0030] like Figure 5 As shown in FIG. 1 , the housing 14 includes a side wall 20, and the side wall 20 surrounds an air passage 21. In addition, the rear end portion, which is one end portion of the housing 14, is an inlet 22 for receiving air from the air passage 21, and the front end portion, which is the other end portion of the housing 14, is an outlet 23 for blowing air from the air passage 21. That is, the air passage 21 is formed between the inlet 22 and the outlet 23 to communicate with each other. The trimmer 15 is mounted on the outlet 23.

[0031] The side wall 20 is formed into a cylindrical shape in the front-to-back direction. In the example shown in the figure, the side wall 20 is formed into a square cylindrical shape. The direction parallel to the central axis of the side wall 20 is the ventilation direction of the ventilation path 21. In the present embodiment, the ventilation direction of the ventilation path 21 is the front-to-back direction, and ventilation is performed from the rear to the front. That is, in the ventilation path 21, the rear side is the upstream side of the ventilation direction, and the front side is the downstream side of the ventilation direction.

[0032] The side wall 20 has a predetermined length in the ventilation direction of the ventilation path 21. In the present embodiment, the side wall 20 is flat in the vertical direction and is formed into a long strip shape, i.e., horizontally long, in the left-right direction. Therefore, the wind direction adjustment device 10 is formed to be thin in the vertical direction and horizontally long in the left-right direction. The side wall 20 integrally includes a pair of side wall portions 20a that are opposed to each other across the central portion of the ventilation path 21, i.e., the central axis of the side wall 20 or the housing 14, and a pair of end wall portions 20b that connect the pair of side wall portions 20a. The pair of side wall portions 20a are opposed to each other in the left-right direction, and the pair of end wall portions 20b are opposed to each other in the vertical direction. The inlet 22 is surrounded by the rear ends of the pair of side wall portions 20a, 20a and the pair of end wall portions 20b, 20b, and the outlet 23 is surrounded by the front ends of the pair of side wall portions 20a, 20a and the pair of end wall portions 20b, 20b.

[0033] The trimmer 15 is an internal component also called a plate or the like. The trimmer 15 has a function as an appearance component of the appearance part of the wind direction adjustment device 10. In the present embodiment, the trimmer 15 is formed in a quadrilateral frame shape. The trimmer 15 integrally includes: a pair of frame side wall portions, i.e., a pair of trimmer side wall portions 15a, which are opposed to each other across the central axis; and a pair of frame end wall portions, i.e., a pair of trimmer end wall portions 15b, which are connected between the pair of trimmer side wall portions 15a. The pair of trimmer side wall portions 15a are opposed to each other in the left-right direction, and the pair of trimmer end wall portions 15b are opposed to each other in the up-down direction. And, the blow-out port 25, which is an opening portion communicating with the outlet 23, is surrounded by these trimmer side wall portions 15a, 15a and the trimmer end wall portions 15b, 15b. That is, the blow-out port 25 is formed in the trimmer 15. In the present embodiment, the blowout port 25 is formed in a quadrilateral shape. In the example shown in the figure, the blowout port 25 is formed in a strip shape in the left-right direction, that is, in a horizontally long shape. In the example shown in the figure, the opening direction of the blowout port 25 is the front-back direction.

[0034] In addition, if Figure 1A , Figure 1B and Figure 5As shown, a fin support portion 27 is formed on the dresser 15 and at the edge of the air outlet 25. In the present embodiment, the fin support portion 27 is formed on each dresser side wall portion 15a. In the example shown in the figure, the fin support portion 27 protrudes from the dresser side wall portion 15a toward the inner side in the left-right direction of the air outlet 25. The fin support portion 27 is formed in a straight line in the left-right direction, and the front end portion is opposite to the side portion of the fin 16. In addition, the fin support portion 27 is located in the approximately central portion of the dresser side wall portion 15a in the up-down direction. In addition, the front end portion 27a, which is the end portion on the appearance side of the fin support portion 27, protrudes forward (front side in the front-back direction) more than the front end portion of the dresser side wall portion 15a. In the present embodiment, the front end portion 27a of the fin support portion 27 is formed in a cylindrical surface shape with the axial direction along the left-right direction. In addition, in the example shown in the figure, the size of the fin support portion 27 in the up-down direction is formed to gradually expand in the up-down direction from the front side to the rear side. That is, the fin support portion 27 is formed so that the front side, which is the outer appearance side, is the thinnest and gradually becomes thicker toward the rear side.

[0035] In the present embodiment, a recess 29 is formed in the fin support portion 27. The recess 29 is formed at the rear portion, that is, the rear side, of the fin support portion 27. The upper and lower parts, the front end portion, and the dresser side wall portion 15a side of the recess 29 are closed, and the rear side and the side opposite to the dresser side wall portion 15a side are opened. In the example shown in the figure, the recess 29 is formed by hollowing out the rear side of the fin support portion 27. Therefore, the size of the recess 29 in the vertical direction is formed to gradually increase in the vertical direction from the front end portion to the rear end portion.

[0036] Figure 5 The fin 16 shown is also called a louver. The fin 16 is arranged to face the blow-out port 25 of the trimmer 15. That is, the fin 16 is located on the downstream side of the air passage 21. The fin 16 is formed in a plate shape. Figure 5 At least one of the upper and lower main surfaces in the vertical direction of the fin 16 serves as a guide surface for guiding the wind. In addition, in the present embodiment, the front end portion 16a as the end portion on the appearance side of the fin 16 is formed into a cylindrical surface shape with the axial direction along the left-right direction. The fin 16 may be single or multiple. In the present embodiment, the fin 16 is composed of a single thin and elongated wind direction adjusting device 10.

[0037] In addition, in the present embodiment, a shaft portion 35 serving as a rotation axis is formed on the fin 16. The shaft portion 35 is formed in a cylindrical shape. In the example shown in the figure, the shaft portion 35 is formed on both sides of the fin 16 in the left-right direction. The left and right shaft portions 35 are located on the same axis. The fin 16 is arranged on the dresser 15 by the shaft portion 35 in a manner that the angle of the guide surface can be changed relative to the ventilation direction. In the example shown in the figure, the fin 16 is supported on the dresser 15 in a manner that can rotate around the shaft portion 35 from a direction in which the guide surface is parallel or substantially parallel to the ventilation direction to a direction that intersects the ventilation direction at an acute angle. In addition, the shaft portion 35 is located near the front end portion of the fin 16 and is arranged coaxially or substantially coaxially with the front end portion of the fin 16.

[0038] The shaft portion 35 is received in the recess 29. In this embodiment, as shown in FIG. Figure 1B As shown, the shaft 35 is accommodated in a bearing 29a formed in the recess 29. The bearing 29a is disposed behind the front end 27a of the fin support 27. The bearing 29a is formed into a cylindrical surface shape capable of sliding contact with the shaft 35.

[0039] The shaft portion 35 is rotatably held in the recess 29 by a holding portion 38 as a cover member. The holding portion 38 is a member separate from the trimmer 15 and the fin 16. The holding portion 38 is mounted in the recess 29. In the present embodiment, the holding portion 38 is formed into a wedge shape with a thin thickness in the vertical direction on the front end portion 38a side as the end on the insertion side and a thick thickness in the vertical direction on the rear end portion 38b side as the end on the opposite side, and is pressed into and fixed in the recess 29 from the back side of the fin support portion 27. That is, the shaft portion 35 is sandwiched from the front and back by the holding portion 38 and the fin support portion 27. That is, the holding portion 38 restricts the position of the shaft portion 35 in the front and back direction in the recess 29. The holding portion 38 is formed of, for example, a synthetic resin.

[0040] In the present embodiment, the retaining portion 38 is fixed to the fin support portion 27 by welding. For example, a pin 40 as a welded portion for welding and fixing the retaining portion 38 is formed in the fin support portion 27. The pin 40 is formed of a synthetic resin. In the example shown in the figure, the pin 40 is formed in a linear shape in the fin support portion 27 along the front-to-back direction and located in the recess 29. The front end portion, i.e., the rear end portion, of the pin 40 protrudes rearward from the fin support portion 27. The number of the pins 40 is set according to the fixing strength of the retaining portion 38 to the fin support portion 27. In the present embodiment, two pins 40 are set on the left and right sides of the recess 29 in the fin support portion 27.

[0041] In addition, a groove 42 into which the pin 40 is inserted is formed in the holding portion 38. In the present embodiment, the groove 42 is formed in a straight line along the front-back direction. The groove 42 and the pin 40 are used to position and guide the holding portion 38 when it is embedded in the recess 29. That is, the groove 42 and the pin 40 have the function of positioning and guiding the embedding of the holding portion 38 and the recess 29. The groove 42 is set according to the number of the pins 40. In the present embodiment, two grooves 42 are set on the upper and lower sides of the holding portion 38, respectively.

[0042] Furthermore, when assembling the wind direction adjustment device 10, Figure 2 As shown, when the shaft portion 35 is received in the bearing portion 29a of the recessed portion 29, as shown in FIG. Figure 3 as well as Figure 4 As shown, the holding portion 38 is embedded in the recessed portion 29. In this embodiment, the holding portion 38 is inserted into the recessed portion 29 from the rear. At this time, the holding portion 38 is positioned relative to the recessed portion 29 by aligning the groove portion 42 with the pin 40, and in this state, the holding portion 38 is pressed forward into the recessed portion 29, thereby being inserted into the recessed portion 29 along the pin 40. Since the recessed portion 29 expands toward the rear, the holding portion 38 can be easily introduced.

[0043] Then, if Figure 1B As shown, when the shaft portion 35 is clamped between the front end portion 38a of the retaining portion 38 and the front end portion 27a of the fin support portion 27, the top end portion of the pin 40 protruding rearward from the rear end portion 38b of the retaining portion 38 is melted and flattened to solidify, thereby forming a weld portion 44, thereby welding and fixing the fin support portion 27 and the retaining portion 38.

[0044] In this state, the shaft portion 35 is located near the center portion in the vertical direction of the air outlet 25, and the shaft portion 35 is rotatably held in the bearing portion 29a of the recess 29. Figure 6 As shown, the front end portion 16a of the fin 16 and the front end portion 27a of the fin support portion 27 are connected to each other in a substantially straight line in the left-right direction.

[0045] Thereafter, the trimmer 15 is assembled to the housing 14 to form the wind direction adjusting device 10 .

[0046] The wind direction adjusting device 10 changes the direction of the air blown out from the air outlet 25 by rotating the fin 16 up and down so that the guide surface is inclined relative to the ventilation direction. The shaft portion 35 of the fin 16 is located coaxially or substantially coaxially with the front end portion 16a, so even if it rotates, the position of the front end portion 16a remains substantially unchanged, and the front end portion 27a of the fin support portion 27 is maintained in a straight line. In addition, the fin 16 can be directly rotated manually by a passenger, can be rotated by a rotating mechanism composed of a dial or a gear, or can be rotated by a rotating mechanism via a motor or the like.

[0047] Thus, according to the first embodiment, since the recess 29 is formed at one of the fin support portion 27 and the fin 16 located at the edge of the air outlet 25 of the dresser 15, and the shaft portion 35 is formed at the other of the fin support portion 27 and the fin 16, the shaft portion 35 is accommodated in the recess 29, and the retaining portion 38 is embedded in the recess 29 and fixed to one of the fin support portion 27 and the fin 16, so that the shaft portion 35 can be rotatably held in the recess 29, the simple structure is adopted. Therefore, the position of the fin 16 relative to the dresser 15 is determined only by the relationship between the recess 29, the retaining portion 38 and the shaft portion 35. Therefore, it is not easily affected by product deviation, that is, dimensional deviation, etc., and can be constructed with high precision, does not require complicated adjustments, and can reduce manufacturing costs.

[0048] Furthermore, the positional relationship between the holder 38 and the shaft 35 can be changed by increasing or decreasing the amount by which the holder 38 is inserted into the recess 29 , so that the operational feeling when the fin 16 is rotated, that is, the feeling of lightness or heaviness of the rotation operation, can be easily adjusted.

[0049] In the present embodiment, the recess 29 is formed in the fin support portion 27 and the shaft portion 35 is formed on the fin 16, thereby eliminating the need to form a fixing structure of the retaining portion 38 on the fin 16, and no unnecessary projections and depressions that may cause turbulence are formed on the guide surface of the fin 16. Furthermore, a larger recess 29 can be obtained without increasing the thickness of the fin 16, and the retaining portion 38 can be installed without impairing the wind direction adjustment function of the fin 16.

[0050] In addition, by forming the recessed portion 29 on the back side of the fin support portion 27 (the back side in the front-to-back direction and the housing 14 side relative to the trimmer 15), when an object collides with the wind direction adjusting device 10, the shaft portion 35 of the fin 16 presses the retaining portion 38 mounted on the recessed portion 29 backward (back side) to peel off the welded portion 44, so that the retaining portion 38 is detached from the recessed portion 29 formed on the back side of the fin support portion 27, and the fin 16 can be quickly detached from the trimmer 15 in a direction away from the object. According to such a structure, the impact on the colliding object can be reduced. In addition, the fixing portion of the retaining portion 38 and the fin support portion 27 is not conspicuous, which can improve the aesthetics.

[0051] By fixing the holding portion 38 by welding, the holding portion 38 can be fixed more appropriately. In addition, since the holding portion 38 is welded by melting and solidifying the pins 40, the number of the pins 40 is set according to the impact level of the purpose when the fin 16 is separated from the trimmer 15, the falling strength of the fin 16 can be easily and freely set, and the impact absorption force of the wind direction adjustment device 10 can be easily adjusted.

[0052] The fin support portion 27 is formed so as to protrude inward from the edge of the air outlet 25, and the front end portion 27a is smoothly connected to the front end portion 16a of the fin 16. That is, the height difference between the front end portion 27a and the front end portion 16a of the fin 16 is reduced in the front-to-back direction or the up-down direction, or both directions. According to such a structure, when the air outlet 25 is viewed from the front side, the front end portion 27a and the front end portion 16a of the fin 16 form an ideal appearance of a substantially straight line across the air outlet 25, which can improve the aesthetics.

[0053] In addition, the recess 29 is made larger on the insertion side of the retaining portion 38, that is, the back side of the fin support portion 27 (the rear side in the front-to-rear direction and the housing 14 side relative to the trimmer 15), so that the retaining portion 38 can be easily inserted into the recess 29, and gradually becomes narrower toward the front side, thereby eliminating the need to increase the thickness of the front end portion 27a side of the fin support portion 27. Therefore, the front end portion 27a of the fin support portion 27 and the front end portion 16a of the fin 16 can be used to form a slender line with good appearance.

[0054] Next, refer to Figure 7 The device of the second embodiment will be described. Note that the same configurations and functions as those of the first embodiment described above are denoted by the same reference numerals and their descriptions are omitted.

[0055] In the present embodiment, the holding portion 38 is locked by fitting with claws in a direction intersecting the direction of insertion from the back side of the fin support portion 27 (the rear side in the front-rear direction and the housing 14 side of the dresser 15 ) into the recess 29 .

[0056] One locking portion 46 is formed on the fin support portion 27 , and another locking portion 47 is formed on the holding portion 38 .

[0057] In the example shown in the figure, one locking portion 46 is an opening portion that opens in a direction (e.g., up and down direction) that intersects the insertion direction of the holding portion 38 into the recessed portion 29, that is, the front-rear direction, and the other locking portion 47 is a claw portion. The above relationship may be reversed, and one locking portion 46 may be a claw portion and the other locking portion 47 may be an opening portion.

[0058] In addition, a positioning portion 48 is formed in the fin support portion 27 and in the recess 29 for positioning the retaining portion 38 in the front-to-back direction, i.e., the insertion direction into the recess 29 , and another positioning portion 49 is formed in the retaining portion 38 for setting the insertion amount of the retaining portion 38 into the recess 29 together with the positioning portion 48 .

[0059] In the example shown in the figure, one positioning portion 48 is formed in a stepped shape inside the recess 29 in the vertical direction intersecting the front-rear direction as the insertion direction of the holding portion 38. In addition, other positioning portions 49 are formed in the upper and lower parts of the holding portion 38 to protrude in a stepped shape.

[0060] When the holding portion 38 is inserted into the recess 29 , one locking portion 46 engages with the other locking portion 47 to fix the holding portion 38 to the recess 29 , and one positioning portion 48 abuts against the other positioning portion 49 to position the holding portion 38 relative to the recess 29 .

[0061] Thus, according to the present embodiment, the holding portion 38 is fixed by simply inserting the holding portion 38 into the recess 29 and engaging the other locking portion 47 with the one locking portion 46, so that the holding portion 38 is easily fixed, and by setting the engagement amount between the one locking portion 46 and the other locking portion 47 according to the impact level intended when the fin 16 is detached from the trimmer 15, the falling strength of the fin 16 can be easily and freely set, and the impact absorption force of the wind direction adjustment device 10 can be easily adjusted.

[0062] In the above-mentioned embodiments, the recess 29 may be formed in the fin 16, the shaft 35 may be formed in the fin support 27, and the holding portion 38 may be fixed to the fin 16. In this case, preferably, the recess 29 is formed to be open on the front end portion 16a side of the fin 16, so that when an object collides with the wind direction adjusting device 10, a force that pushes relatively forward from the shaft 35 acts on the holding portion 38, so that the holding portion 38 is separated from the fin 16, and the fin 16 can be quickly separated from the trimmer 15 in a direction away from the object.

[0063] In addition, the two sides of the fin 16 are made to have the same structure, but not limited to this. The retaining structure of the recess 29, the shaft portion 35 and the retaining portion 38 can also be applied only on one side of the fin 16. It can also be configured that the recess 29 is formed in the fin support portion 27 and the shaft portion 35 is formed in the fin 16 on one side of the fin 16, and the recess 29 is formed in the fin 16 and the shaft portion 35 is formed in the fin support portion 27 on the other side of the fin 16, etc.

[0064] Several embodiments of the present invention have been described above, but these embodiments are presented as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the scope of the subject matter of the invention. These embodiments and their variations are included in the scope or subject matter of the invention, and are included in the invention described in the claims and their equivalents.
