【Technical field】

 The present invention relates to an air outlet device for a vehicle, and in particular, the direction of blown air is controlled by the rotation of a barrel mounted inside a housing and the rotation of a plurality of wind direction plates arranged on the barrel. The present invention relates to an air outlet device that can be changed vertically and horizontally.

[0002]

[Background technology]

 As an air outlet device that blows air into the vehicle interior, (a) a housing that opens into the vehicle interior, and (b) a tubular barrel that is rotatably mounted around the first axis in the opening of the housing. And (c) a plurality of wind directions arranged inside the barrel in a state of integrally rotating with the barrel about the first axis and relatively rotatable with respect to the barrel about the second axis. There is known a type having a plate (blade) and changing the direction of the blade and the barrel to change the direction of the blown air. Japanese Utility Model Publication No. 2-33075 discloses an air outlet device in which the direction of blown air is continuously changed by automatically swinging a blade.

FIG. 7 shows an example of an air outlet device having such an automatic wind direction adjusting function. Therein, 2 is a cylindrical barrel, which is mounted in the opening of the housing 4 in a state of being rotatable about the first axis: A. In addition, inside the barrel 2, a plurality of units are provided in a state where the barrel 2 and the barrel 2 are integrally rotatable about a first axis: A and a second axis: B are rotatable relative to the barrel 2. A vertical blade 6 is provided. The plurality of vertical blades 6 are connected to each other by the interlocking plate 16, and the power is transmitted to the rod portion 8 formed at the rear portion of the central vertical blade 6, so that the plurality of vertical blades 6 are connected. Are linked together so that they can be swung together.

Further, the power given by a predetermined driving means such as a motor is converted into a linear reciprocating motion of the reciprocating plate 18 arranged outside the housing 4, and the clutch mechanism 24 and the U-shaped structure. From the U-shaped engaging piece 10 that is transmitted to the shaft 14 arranged behind the barrel 2 in the housing 4 via the arm 20 having the engaging groove 22 and is further rotated integrally with the shaft 14, It is adapted to be transmitted to the vertical blade 6 by being transmitted to the rod portion 8 of the vertical blade 6 which engages with the U-shaped groove portion 12.

Further, in this apparatus, since the clutch mechanism 24 is provided between the reciprocating plate 18 and the shaft 14, the vertical blade 6 can be automatically or manually rotated. is there. That is, since the clutch mechanism 24 is brought into contact with the reciprocating plate 18 with a predetermined frictional force by the urging force of the spring housed in the case, it is moved integrally with the reciprocating plate 18. As a result, the vertical blade 6 automatically swings, but when a force greater than the friction force is applied, the reciprocating plate 18 and the clutch mechanism 24 move relative to each other. By operating the operation knob 26 of the vertical blade 6 manually, the orientation of the vertical blade 6 can be changed manually.

However, such an air outlet device has some problems as described below. That is, one is that the rod portion 8 of the vertical blade 6 is formed into an arc shape so that the rod portion 8 has a U-shaped groove portion of the U-shaped engaging piece 10 regardless of the rotation position of the barrel 2. However, due to such a shape of the rod portion 8, the rotation position of the barrel 2 causes the rod portion 8 with respect to the U-shaped engaging piece 10 as shown in FIG. The distance between the engaging parts (P ₁ , P ₂ , P ₃ ...) And the second axis B is changed. Therefore, since the rotation angle of the shaft 14 is always constant, the deflection angle of the vertical blade 6 changes depending on the rotation position of the barrel 2, and in some cases, the vertical blade 6 hardly swings. There was a problem.

Further, in the air outlet device, since the shaft 14 and the U-shaped engaging piece 10 are present in the housing 4, there is a problem that the ventilation resistance becomes large and the ventilation efficiency of the air outlet decreases. It was

Further, in the air outlet device, the clutch mechanism 24 is provided so that the vertical blade 6 can be manually rotated. However, between the vertical blade 6 and the clutch mechanism 24. Since the U-shaped engaging piece 10, the shaft 14, and the arm 20 are present in the clutch mechanism 24, the transmission loss of the load for operating the operation knob 26 increases. Therefore, the load applied to the operation knob 26 is applied to the clutch mechanism 24. Had to be considerably larger than the frictional force of, and there was a problem that the operation feeling deteriorated. One possible solution to this drawback is to reduce the frictional force of the clutch mechanism 24. In this method, however, the temperature inside the vehicle rises in the summer and the shaft 14 made of synthetic resin is rotated. When the moving shaft and the rotating shaft of the vertical blade 6 expand and the frictional force between the housing 4 and the barrel 2 increases, the clutch mechanism 24 slips and the vertical blade 6 has an automatic wind direction adjusting function. Will be lost.

[0009]

[Solution]

 The present invention has been made in view of such a situation, and the problem to be solved is to solve the problem of the rotation of the barrel in the air outlet device that automatically changes the direction of the wind direction blade (blade). The aim is to keep the deflection angle of the blade constant regardless of the moving position. Further, it is to improve the ventilation efficiency of the air outlet by removing the shaft and the U-shaped engaging piece from the inside of the housing. In addition, when a clutch mechanism is installed and the blade direction can be changed manually, the operating load is directly transmitted to the clutch mechanism, and the operation is performed with a load that is slightly larger than the friction force of the clutch mechanism. To improve the operation feeling.

【Example】

 Hereinafter, in order to clarify the present invention more specifically, a typical embodiment of a vehicle air outlet device having a structure according to the present invention will be described in detail with reference to the drawings.

First, FIG. 1 is a sectional view showing an example of a vehicle air outlet device according to the present invention. Here, 34 is a housing that opens into the passenger compartment, and the upper and lower parts of the opening 35 are arcuate concave surfaces. In addition, a cylindrical barrel 32 is fitted in the opening 35 such that the arcuate concave surfaces of the fitting parts 30 formed on the upper and lower portions are fitted to the arcuate concave surfaces thereof. The barrel 32 is configured to be rotatable within the opening 35 around an axis (first axis: A) of a mounting shaft (not shown) with respect to the housing 34. With this rotation, the direction of the air outlet is changed vertically in FIG. Reference numeral 33 is a horizontal blade fixedly provided on the barrel 32.

Inside the barrel 32, a plurality of vertical blades 36 are attached behind the horizontal blade 33 in a state of being aligned in a horizontal row. The vertical blade 36 is rotatable about a second axis B (axis of the mounting shaft 37 with respect to the barrel 32) perpendicular to the first axis A. As a result, the direction of the air blown out from the air outlet can be changed in the direction perpendicular to the paper surface in FIG. The plurality of vertical blades 36 are connected to each other by an interlocking plate 38, so that the plurality of vertical blades 36 are interlocked and can be simultaneously rotated.

On the other hand, on the lower surface of the housing 34, there is a reciprocating plate 40 for transmitting the rotation of a motor (not shown) by a cam (not shown) to convert it into a linear reciprocating motion. Is arranged so as to be linearly reciprocally movable in a direction substantially perpendicular to the above (a direction perpendicular to the paper surface in FIG. By the way, the reciprocating plate 40 is integrally formed with an extending portion 42 extending from the side surface thereof in the rotation direction of the barrel 32, and on the extending portion 42, the first axis: An arcuate guide groove 46 having A as the center of the arc is formed so as to extend in the rotation direction of the barrel 32. The extension 42 is located in the opening 35 of the housing 34 through a window 44 provided on the lower surface of the housing 34.

The reciprocating plate 40 is engaged with the guide groove 46 of the extending portion 42 and abutted on the central one of the plurality of vertical blades 36 with a predetermined frictional force. A clutch mechanism 50 is provided so that the vertical blade 36 can be integrally moved by the power transmitted from the reciprocating plate 40 under the connection state by the clutch mechanism 50. . Further, by releasing the connection by the clutch mechanism 50, the vertical blade 36 and the reciprocating plate 40 can be moved relative to each other.

More specifically, the clutch mechanism 50 is composed of the parts shown in FIG. 2, and is provided on the small diameter portion of the stepped cylindrical mounting jig 52 having a large diameter portion and a small diameter portion. On the other hand, while the spring receiver 54 and the E-ring 56 for retaining are fitted to each other, a spring 58 is externally mounted on the large diameter portion, and further, the large diameter portion of the mounting jig 52 and the spring 58 are substantially It is accommodated in a spring case 60 having a bottomed cylindrical shape. Then, in such an assembled state, the pin portion 64 formed integrally with the cylindrical wall portion of the spring case 60 projects downward from the small diameter portion of the mounting jig 52.

In the clutch mechanism 50, the pin attachment shaft 37 below the vertical blade 36 is inserted into the through hole formed in the center of the bottom of the spring case 60 and the inner hole of the attachment jig 52, so that Only the portion 64 is mounted inside the barrel 32 in a state of being projected downward from the barrel 32. In this manner, the bottom outer surface 62 of the spring case 60 is brought into contact with the disc-shaped contact portion 66 formed integrally with the vertical blade 36 with a predetermined frictional force based on the biasing force of the spring 58. The pin portion 64 that is brought into contact with and integrally formed with the spring case 60 is engaged with the arc-shaped guide groove 46 of the reciprocating plate 40. That is, here, the bottom outer surface 62 of the spring case 60 serves as the friction surface of the clutch mechanism 50, while the pin portion 64 integrally formed on the spring case 60 transmits the power from the reciprocating plate 40. It is a transmission section.

Therefore, in such an air outlet device, when the reciprocating plate 40 is reciprocally moved by a predetermined driving means such as a motor, the pin portion 64 moves in the guide groove 46 of the reciprocating plate 40. By being guided, the clutch mechanism 50 is rotated, and the central vertical blade 36 that comes into contact with the clutch mechanism 50 with a predetermined frictional force is rotated about the second axis: B. As a result, the plurality of vertical blades 36 connected by the interlocking plate 38 are simultaneously rotated. That is, the direction of the vertical blade 36 is automatically changed, and the wind direction is automatically adjusted in the left-right direction.

In order to switch the wind direction up and down in this device, the barrel 32 is manually rotated around the first axis: A. At that time, the vertical blade in the barrel 32 is rotated. The clutch mechanism 50, which is brought into contact with 36 with a predetermined frictional force, is also moved, and the pin portion 64 thereof is moved in the guide groove 46 of the reciprocating plate 40. Even if the pin portion 64 is located in the guide groove 46, the amount of movement of the pin portion 64 due to the reciprocating movement of the reciprocating plate 40, that is, the amount of rotation of the clutch mechanism 50 does not change. The swing angle is always constant.

In addition, in such an air outlet device, as compared with the conventional device, since the shaft and the U-shaped engaging pieces are eliminated, the ventilation resistance is reduced and the ventilation efficiency of the air outlet is reduced. There is an effect that can be improved. Further, since the shaft and the U-shaped engaging piece are eliminated, the number of parts is reduced, and there is an advantage that the cost and the number of assembling steps can be reduced.

In addition, in the apparatus of this embodiment, the operation knob 68 formed integrally with the vertical blade 36 is operated by a force greater than the frictional force applied to the friction surface of the clutch mechanism 50 to move the operation knob 68. The orientation of the blade 36 can be changed manually, and at that time, since the friction surface of the clutch mechanism 50 is brought into direct contact with the vertical blade 36, the load applied to the operation knob 68 is directly applied. It is transmitted to the clutch mechanism 50. Therefore, since there is no power transmission loss, it is possible to change the direction of the vertical blade 36 with a force slightly larger than the frictional force of the clutch mechanism 50, and the operation feeling during manual operation is extremely good. Of.

By the way, in the above embodiment, the friction surface of the clutch mechanism 50 is brought into contact with the vertical blade 36, but it is also possible to bring the friction surface of the clutch mechanism into contact with the interlocking plate. FIGS. 3 and 4 show an example of a vehicle air outlet device according to the present invention having such a structure.

Therein, 72 is a vertical blade attached to the tubular barrel 70 by an attachment shaft 74, and an engagement shaft 76 provided behind the attachment shaft 74 is an interlocking plate 78. A plurality of vertical blades 72 are connected to each other by the interlocking plate 78 by being inserted into the elongated hole-shaped engaging holes 80. Further, as shown in FIG. 4, the interlocking plate 78 is provided with a pair of side wall portions 82, and a partition wall 84 is formed in the middle of the side wall portions 82 in the depth direction. The clutch mechanism 86 is fitted so as to be brought into contact with the side wall portion 82 and the partition wall 84.

The clutch mechanism 86 includes an H-shaped main body 88 having U-shaped notches on two opposite side surfaces, a pin portion 90 integrally formed on the main body 88 as a power transmission portion, and The spring 92 is attached to the U-shaped notch. The side surface 94 (friction surface) of the main body 88 is brought into contact with the side wall portion 82 of the interlocking plate 78 with a predetermined friction force by the urging force of the spring 92. Further, the clutch mechanism 86 is to be assembled to the assembling recess formed in the fitting portion 71 on the lower side of the barrel 70. In this state, the pin portion 90 is not fitted to the fitting portion 71. Through, and projects downward, so that it can be engaged with the arcuate guide groove 98 of the reciprocating plate 96 arranged on the lower surface of the barrel 70.

Therefore, even in such an air outlet device, when the wind direction is automatically changed, the swing angle of the vertical blade 72 becomes constant regardless of the rotational position of the barrel 70, and it is manually operated. When the vertical blade 72 is rotated, the transmission loss of the dynamic force to the clutch mechanism 86 can be reduced and the operation feeling can be improved, and the same effects as those of the above-described embodiment can be obtained. Of.

Next, a further different example of the vehicle air outlet device according to the present invention will be described with reference to FIGS. 5 and 6. In FIG. 5, reference numeral 100 denotes a housing, and a cylindrical barrel 104 is fitted in an opening 102 of the housing. The barrel 104 has an axial center (first shaft) of a mounting shaft (not shown) with respect to the housing 100. It is adapted to be rotatable in the opening 102 around an axis: A).

A plurality of vertical blades 106 are mounted inside the barrel 104, and the vertical blades 106 have a second axis B, which is perpendicular to the first axis A and is B ( It is rotatable about the axis of the mounting shaft 107 with respect to the barrel 104. Further, as shown in FIG. 6, in the plurality of vertical blades 106, the engagement shaft 108 provided behind the attachment shaft 107 is inserted into the elongated groove 112 of the interlocking plate 110. By doing so, they are connected and can be rotated in unison with each other. As described above, the interlocking plate 110 constitutes an interlocking member, but in the present embodiment, the pin portion 114 integrally provided on the interlocking plate 110 is provided in the second reciprocating plate 120 described later. The interlocking plate 110 is configured to also have the function of a connecting member by being engaged with the guide groove 126 provided in the extending portion 124.

On the other hand, on the lower surface of the housing 100, the rotation of a motor (not shown) is transmitted by a cam (not shown), and is converted into a linear reciprocating motion. Is arranged so as to be linearly reciprocable in a direction substantially perpendicular to the second axis B (the direction perpendicular to the paper surface in FIG. 1). Reference numeral 115 is an engagement hole that engages with the cam. Then, the second reciprocating plate 120 is engaged with the engaging shaft 118 provided on the lower surface of the first reciprocating plate 116 in the elongated hole-like engaging hole 122, and is urged. The plate 130 is engaged in the engagement hole 132. Further, a spring 134 is mounted on the engaging shaft 118, and a washer 136 is fixed to prevent the spring from coming off.

With such an assembly, the upper surface (friction surface) of the second reciprocating plate 120 comes into contact with the first reciprocating plate 116 with a predetermined frictional force based on the urging force of the spring 134. It is being made. Therefore, the first and second forward / backward movement plates 116 and 120 can be integrally moved under the connection state based on the frictional force, while a force larger than the frictional force is applied. As a result, the connection is released and the relative movement is made possible.

By the way, the second reciprocating plate 120 is integrally formed with an extending portion 124 extending from the side surface thereof in the rotation direction of the barrel 104, and on the extending portion 124. An arc-shaped guide groove 126 having the first axis: A as the center of the arc is formed so as to extend in the rotation direction of the barrel 104. The extending portion 124 is located in the opening 102 of the housing 100 through the window portion 128 provided on the lower surface of the housing 100.

Then, the pin portion 114 of the interlocking plate 110 is engaged with the guide groove 126 provided in the extending portion 124 of the second reciprocating plate 120, thereby The pin portion 114 serves as a power transmission portion and transmits power from the second reciprocating plate 120.

Therefore, in such an air outlet device, when the first reciprocating plate 116 is reciprocated by a predetermined driving means such as a motor, the second reciprocating plate 120 is integrated. And a plurality of vertical blades via a driving plate 110 that engages with a guide groove 126 provided in an extending portion 124 of the second reciprocating plate 120 at a pin portion 114. The 106 is simultaneously rotated about the second axis: B. That is, the direction of the vertical blade 106 is automatically changed, and the wind direction is automatically adjusted in the left-right direction.

When the vertical blade 106 is manually operated, the operation knob 109 formed integrally with the vertical blade 106 is operated with a force larger than the friction force applied to the friction surface of the second reciprocating plate 120. Then move it.

Then, in order to switch the wind direction to the up-down direction in this device, the barrel 104 is manually rotated around the first axis: A. At that time, the vertical direction in the barrel 104 is changed. The interlocking plate 110 assembled to the blade 106 is also moved together, and the pin portion 114 thereof is moved within the guide groove 126 of the second reciprocating plate 120. And, no matter where the pin portion 114 is located in the guide groove 126, the amount of movement of the pin portion 114 due to the reciprocating movement of the second reciprocating plate 120, that is, the amount of movement of the interlocking plate 110, does not change. The swing angle of the blade 106 is always constant.

Further, in the device of this embodiment, in comparison with the conventional device, the shaft and the U-shaped engaging piece are omitted, and in addition, the clutch mechanism is not provided in the barrel 104. Since the first and second reciprocating plates 116 and 120 are provided with the clutch mechanism substantially outside the housing 100, the ventilation resistance of the air outlet is made extremely small. It has the characteristic that the efficiency can be improved more advantageously. Furthermore, since the shaft and the U-shaped engaging piece are eliminated, the number of parts is reduced, and there is an advantage that the cost and the number of assembling steps can be reduced.

The representative embodiments of the vehicle air outlet device according to the present invention have been described above in detail. However, the present invention is not subject to any restrictions due to the description of such embodiments. Needless to say. Further, in addition to the above-described embodiments, the present invention may be variously modified, modified, improved, etc. based on the knowledge of those skilled in the art without departing from the spirit of the present invention. Should be understood.

For example, the clutch mechanism can be configured in various forms other than the configuration of the above-described embodiment, and the friction surface and the vertical blade or the interlocking member can be brought into contact with each other, and the power transmission unit and the reciprocating motion. The engagement form of the guide groove of the plate can be variously changed.

Further, the contact form of the first and second reciprocating plates, etc. can be implemented in various forms other than the configuration of the above-mentioned embodiment. For example, as the contact form of the first and second reciprocating plates, the contact form of the interlocking plate 78 and the main body 88 of the clutch mechanism 86 as shown in FIG. The second reciprocating plate is formed in an H shape, and the extending portion is integrally formed from the side surface of the second reciprocating plate, and the arc-shaped guide groove is formed in the extending portion. May be provided.

Further, in order to obtain a necessary frictional force on the friction surfaces of the clutch mechanism and the second reciprocating plate, a leaf spring or the like may be used in addition to the springs described in the embodiments.

[Effect of device]

 As is clear from the above-mentioned details, in such an air outlet device for a vehicle, the reciprocating member is reciprocated by a predetermined driving means so that the plurality of wind direction plates are rotated around the second axis. The wind direction can be changed left and right by automatically turning all at once. Even if the barrel is rotated about the first axis to change the wind direction in the vertical direction, the connecting member or the power transmission portion of the clutch mechanism is always positioned in the arc-shaped guide groove of the reciprocating member. Therefore, the amount of movement of the dynamic force transmission part due to the reciprocation of the reciprocating member does not change, so the amount of movement of the connecting member or the clutch mechanism does not change, and the swing angle of the wind direction plate does not change. It will always be constant.

Further, in such an air outlet device, as compared with the conventional device, since the shaft and the U-shaped engaging piece are eliminated, there is an effect that the ventilation efficiency of the air outlet can be improved. In particular, when the clutch mechanism is provided outside the barrel by providing the first and second reciprocating members as compared with the case where the clutch mechanism is provided inside the barrel, the ventilation resistance is extremely high. It can be effectively reduced, ventilation efficiency is improved, and air conditioning performance is greatly improved. Further, since the shaft and the U-shaped engaging piece are eliminated, the number of parts is reduced, and there is an advantage that the cost and the number of assembling steps can be reduced.

On the other hand, when the clutch mechanism is provided in the barrel and its friction surface is brought into direct contact with the wind direction plate or the interlocking member, in the manual operation, the operating load is directly transmitted to the clutch mechanism and the power is transmitted. Since the transmission loss of the wind direction plate can be changed with a force slightly larger than the frictional force of the clutch mechanism, there is an advantage that the operation feeling is extremely improved.
