BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle wind direction control device capable of automatically changing the direction of air blown from an opening of a housing, and more particularly to a technique capable of advantageously achieving compactness of the device. is there.

[0002]

2. Description of the Related Art Conventionally, in a vehicle interior air conditioner or the like, a plurality of blades (airflow direction vanes) rotatably provided in parallel with each other in an opening of a housing forming an air outlet to the vehicle interior. ) Is linked with a connecting member, and automatically swings by a predetermined driving means to change the blowing direction of the wind.

In such a wind direction control device, a moving member which is linearly reciprocated by a driving means is provided to be supported by the housing, and the reciprocating motion of the moving member is controlled by a predetermined power transmission member. ,
It is common to convert the blade into a rotational movement so that the blade swings.
In order to obtain good operating performance, it is desirable to guide such a moving member in its reciprocating direction so as to reduce sliding resistance and prevent backlash.

Therefore, conventionally, a support shaft projectingly formed on the housing is inserted into an elongated hole provided in the moving member and extending in the moving direction, and a pressing member such as a chrysanthemum washer is fixed to the tip of the support shaft. In the holding structure in which the moving member is slidably pressed against the housing by the pressing member (see Japanese Utility Model Laid-Open No. 60-23409, etc.), the pressing member and the moving member can be improved. It is proposed that an urging means for exerting an urging force based on an elastic deformation action is interposed between the ??? and ???, and the moving member is pressed against the housing via the elastic force by the urging means. Has been done.

A coil spring or the like may be used as the biasing means, but from the viewpoint of cost and installation space, as shown in FIG.
A main body portion 4 having an insertion hole 2 through which a support shaft provided in the housing is inserted is extended to a predetermined length on both sides in the moving direction of the moving member, and its tip portion is given to the moving member side. A biasing means having a substantially plate-like spring structure, which is integrally provided with four elastic pieces 6 projecting at a height, is used (see Japanese Utility Model Laid-Open No. 63-113850).

However, the biasing means having such a structure has the elastic pieces 6 extending to both sides of the main body portion 4, and the projecting length of the elastic pieces 6 is equal to the elastic deformation amount. In order to obtain a stable urging force and to obtain a stable urging force, it cannot be shortened too much, and there is an inherent problem that a large installation space is required in plan view.

Therefore, when such an urging means is used, it is difficult to make the wind direction control device compact, so that the degree of freedom in design is limited, and the device can be miniaturized in vehicle design or structural design. When it is required, the space for urging means must be secured, so that the demand cannot be satisfied in some cases.

Further, when the moving member is held against the biasing means as described above, such movement is performed in order to impart excellent slidability to a contact portion between the biasing means and the moving member. The contact surface of the biasing means in the member needs to be a smooth surface with high surface accuracy, but in the conventional biasing means as shown in FIG. 9, it projects to both sides of the main body portion 4. Since the tip end portion of each elastic piece 6 is brought into contact with the moving member, a range in which high surface accuracy is required in the moving member is wide, and its manufacturing or processing is troublesome. He also had problems.

[0009]

The present invention has been made in view of the circumstances as described above, and a problem to be solved by the present invention is that the device is interposed between a pressing member and a moving member. A vehicular wind direction control device comprising a holding member having a novel structure, which can hold a moving member with respect to a housing with a stable elastic force, and can also achieve a reduction of an installation space.

A wide engaging portion 38 having an engaging hole 36 extending in a direction substantially perpendicular to the moving direction of the moving plate 30 is integrally formed on one end side in the longitudinal direction of the moving plate 30. It is provided. Then, the eccentric shaft 44 of the pin wheel 42 mounted on the output shaft of the motor 40 as a driving unit arranged laterally of the housing 10 is engaged with the engaging hole 36 of the engaging portion 38. ing. As a result, the pin wheel 42 is applied to the motor 40.
By rotating the moving plate 30,
It is designed to be reciprocally moved in the longitudinal direction. Incidentally, in the figure, reference numeral 46 indicates the O of the operation of the motor 40.
This is a switch for performing N / OFF.

As is apparent from the above description, in this embodiment, the moving plate 30, the engaging hole 36 provided in the moving plate 30, the motor 40 and the output shaft of the motor 40 are mounted. A drive mechanism is configured by the pin wheel 42 and the like.

Further, a holding plate 50 having a long hole 48 extending in a predetermined length in the longitudinal direction is fixed to the moving plate 30, and is formed between the moving plate 30 and the holding plate 50. In the space, a movable body 54 having an engagement pin 52 protruding outward through the elongated hole 48 is accommodated and arranged so as to be reciprocally movable in the longitudinal direction of the moving plate 30. That is, in the movable body 54 including the engaging pin 52, the moving plate 3
In the longitudinal direction of 0, when an external force larger than the sliding resistance exerted by the sliding contact with the movable plate 30 and the pressing plate 50 is exerted, the movable plate 30 can be relatively displaced.

On the other hand, the air outlet 1 of the housing 10
A driving force transmission rod 56 is disposed behind the barrel 14 in the space 2 between the upper and lower wall portions of the housing 10, and is supported by the housing 10 so as to be rotatable about its axis. . Then, this driving force transmission rod 56
An input arm 58 that extends in the direction perpendicular to the axis toward the moving plate 30 side is integrally provided at the upper end of the housing 10 that protrudes through the upper wall of the housing 10. The engaging pin 52 of the movable body 54 is engaged with the tip of the.

Further, an output arm 60 extending in a direction perpendicular to the axis toward the opening side (barrel 14 side) of the housing 10 is integrally provided at a substantially central portion in the axial direction of the driving force transmitting rod 56. ing. Further, the central vertical blade 22 provided with the operation knob 28, which is disposed in front of the output arm 60, has the second rotary shaft of the vertical blade 22 at the rear edge portion thereof. An engaging rod 62 extending substantially in the same direction as 24 is integrally provided. The tip end of the output arm 60 is engaged with the engagement rod 62.

That is, the reciprocating movement of the moving plate 30 driven by the motor 40 is
Through the rotational movement of the driving force transmission rod 56, all the vertical plates 22 that are transmitted to the vertical plate 22 and are coupled by the coupling plate 26 are automatically swung. Thus, the blowing direction of the air from the air outlet 12 can be automatically changed in the horizontal and horizontal directions. As is clear from this, in the present embodiment, the input / output arms 58, 6 are
The driving force transmission rod 56 having zero, the engagement rod 62 provided on the vertical blade 22, and the like constitute a power transmission member.

When the motor 40 is stopped, the driving force transmission rod 56 is rotated based on the relative displacement of the movable body 54 with respect to the moving plate 30.
Since it can be allowed independently of 0, a rotary operation force equal to or larger than the sliding resistance force of the movable body 54 is input to the vertical blade 22 through the operation knob 28, whereby the manual operation is performed. It is possible to rotate the vertical blade 22 in any direction. As is clear from this, in the present embodiment, the clutch mechanism is configured by the sliding mechanism under the predetermined resistance of the movable body 54 with respect to the moving plate 30.

Further, in the moving plate 30 which constitutes the power transmission mechanism for automatically rotating the vertical blade 22 in this manner, at least a length corresponding to the moving stroke in the moving direction is provided at a substantially middle portion in the longitudinal direction thereof. An elongated hole 64 that extends is provided. Also, the housing 10
A support shaft 66, which is inserted into the elongated hole 64 and projects outward, is integrally formed with the shaft. Then, the support shaft 6 protruding through the elongated hole 64
The holding member 68 is attached to the tip of the mounting bolt 70.
Are integrally fixed by means of the holding member 6
Since the moving plate 30 is pressed against the housing 10 side by 8,
It is possible to prevent the above from rising from the housing 10 and to exhibit stable slidability (reciprocal movement).

Here, as shown in FIGS. 7 and 8, the holding member 68 has a main body 78 having a substantially rectangular flat plate shape, and is provided at the center of the main body 78. The mounting bolt 70 is inserted through the insertion hole 72. Further, in the main body portion 78, at both side corner portions that are opposed to each other in the diagonal direction with the insertion hole 72 interposed therebetween, the outer peripheral edge portions are formed toward the respective corner portions that are opposite to each other in the diagonal direction. A first elastic projection piece 74 and a second elastic projection piece 76, which extend in parallel with each other and extend in the same circumferential direction, are integrally provided.

The first and second elastic protruding pieces 7 are also provided.
4 and 76 are each formed to be curved so as to gradually project toward one side in the thickness direction of the main body portion 78 as it goes to the tip end side. Furthermore, the holding member 68 integrally provided with the first and second elastic projecting pieces 74, 76 is formed of an elastic material such as a resin material or spring steel, whereby the first and second elastic protruding pieces 74, 76 are formed. Elastic deformation can be allowed with respect to the second elastic projection pieces 74 and 76.

As described above, in the holding member 68 having such a structure, the main body 78 is fixed to the support shaft 66 of the housing 10 by the mounting bolt 70, as described above. , The first and second elastic protruding pieces 7
4 and 76 extend in the longitudinal direction of the moving plate 30 and are mounted in a state of being projected toward the moving plate 30 side. That is, under such a mounting state of the holding member 68, the first and second elastic protruding pieces 74, 7 are
6 are respectively brought into contact with the moving plate 30 and elastically deformed by a predetermined amount, whereby the elastic force based on the elastic deformation of the holding member applies a pressing force to the moving plate 30. As a result, the moving plate 30 can be pressed against the housing and slidably held.

Then, there, the holding member 6
In the first and second elastic projecting pieces 74 and 76 in FIG. 8, respectively, one corner of the main body 78 faces each diagonally opposite position to the other diagonally opposite corner. Since it is formed so as to extend along the outer peripheral edge portion of the main body portion 78, the amount of protrusion of the first and second elastic protruding pieces 74 and 76 from the main body portion 78 to the outside is extremely small. It can be advantageously suppressed.

Therefore, as compared with the holding member having the conventional structure as shown in FIG. 9, the space for arranging the holding member can be reduced, and the size of the wind direction control device for a vehicle can be reduced. It is possible to deal with the demand for
Thus, the degree of freedom in designing such a vehicle wind direction control device, and by extension, various devices arranged on the back side of the instrument panel, can be advantageously improved.

Moreover, in the holding member 68 as described above, the first and second elastic projecting pieces 74, 76 have the body portion 7
Since it is projected along the outer peripheral edge of 8,
The length: a (see FIG. 7) of the first and second elastic projecting pieces 74, 76 can be extremely effectively secured while suppressing the outward projecting amount from the main body 78. .

Therefore, in the holding member 68, the elastic deformation allowances: b (see FIG. 8) of the first and second elastic projection pieces 74 and 76 are ensured while ensuring a compact planar form. This can be advantageously ensured, and thereby, even when the elastic deformation amounts of the first and second elastic protruding pieces 74 and 76 change due to component dimensional errors or the like,
The pressing force exerted on the moving plate 30 can be advantageously stabilized, and the decrease in the pressing force due to the settling of the first and second elastic protrusions 74, 76 can be effectively reduced or reduced. Moving plate 3 from where it can be prevented
Therefore, the holding of 0 to the housing 10 can be stably performed with excellent sliding performance.

According to the holding member 68 as described above,
Since there are two contact points on the moving plate 26 and all of these contact points are located very close to the main body portion 78, the holding member of the conventional structure as shown in FIG. 9 is used. Compared with the case where it is used, the sliding contact area of the holding member 68 in the moving plate 26, that is, the range where high surface accuracy is required to obtain good slidability, can be effectively reduced. Therefore, the manufacturability or workability of the holding plate 26 can be advantageously improved.

The embodiments of the present invention have been described in detail above, but these are literal examples, and the present invention should not be construed as being limited to such specific examples.

For example, in the above embodiment, the main body 78 of the holding member 68 was formed in a substantially rectangular flat plate shape, but the main body 78 is attached to the support shaft 66 erected on the housing 10. Any shape can be used as long as it can be fixedly attached, and the shape is not limited, and it is also possible to form a disk shape or the like.

Further, in the wind direction control device according to the above-mentioned embodiment, the plurality of vertical blades 22 are connected to each other by the first rotary shaft 1
The housing 1 is provided via a barrel 14 which can be rotated about 6 times.
Although the barrel 14 is not necessarily required, the vertical blades 22 may be directly and rotatably attached to the housing 10.

Further, in the wind direction control device of the above-mentioned embodiment, the vertical blade 22 is adapted to be automatically swung. However, instead of or in addition to this, the horizontal blade 20 is automatically swung. It is also possible to configure so that it can be performed.

Further, the power transmission mechanism for transmitting the reciprocating motion of the moving member to the blade to rotate the blade is limited to the one using the driving force transmission rod 56 as employed in the above embodiment. Never be done,
Various conventionally known mechanisms, such as those disclosed in Japanese Utility Model Laid-Open No. 60-23409, can be adopted.

Further, the clutch mechanism for cutting off the power transmission by the power transmission member to enable the manual operation of the blade is not limited to that of the above-mentioned embodiment, but is disclosed in Japanese Utility Model Laid-Open No. 60-23409. Various conventionally known mechanisms as disclosed in, for example, can be adopted.

Further, in the above embodiment, the moving plate 2
Although one holding member 68 is provided to hold the six members, the number of holding members is not limited, and the length of the moving plate 26 and the magnitude of the external force acting on the moving plate 26 are not limited. It can be appropriately set according to the above.

Although not listed one by one, the present invention

It goes without saying that all such embodiments are included in the scope of the present invention without departing from the spirit of the present invention.

[0041]

As is apparent from the above description, in the vehicular wind direction control device having the structure according to the present invention, the first and second elastic members of the holding member exerting a pressing force on the moving member. Since the piece is formed so as to extend along the outer peripheral edge portion of the holding member, the outward projection amount of the first and second elastic pieces is determined by the length and the elastic deformation allowable amount. It is possible to reduce the planar arrangement space of the holding member while sufficiently securing the stability of the pressing force exerted on the moving member while sufficiently securing the As a result, the demand for downsizing of the vehicle wind direction control device can be advantageously dealt with.

In the vehicle wind direction control device, the contact points of the holding member with respect to the moving member are two points on the first and second elastic pieces, and the contact points are very close to each other. Since it is located at, it is possible to effectively reduce the sliding contact area of the holding member in the moving member, that is, the range in which high surface accuracy is required to obtain good slidability. The manufacturability or workability of the moving member can be advantageously improved.
