Description

  The present invention relates to an air blowing device for a vehicle.

  2. Description of the Related Art Conventionally, an air blowing device has been proposed that can adjust the flow direction of air blown when supplying air for air conditioning, for the purpose of adjusting the indoor environment of a vehicle (automobile or the like).

  One of the conventional air blowing devices (hereinafter referred to as “conventional device”) includes a retainer that defines an air flow path, and a plurality of wind direction adjusting plates that are rotatably supported inside the retainer. ing. The conventional apparatus can adjust the flow direction of the air blown from the air blowing device by adjusting the rotation angle of the plurality of wind direction adjusting plates (see, for example, Patent Document 1). Hereinafter, for the sake of convenience, the flow of air blown from the air blowing device is referred to as a “blown air flow”.

JP 2009-160981 A

  A vehicle air blowing device generally has a plurality of independent members (for example, a retainer, a wind direction adjusting plate, a mechanism for adjusting a rotation angle of the wind direction adjusting plate, etc.) as exemplified by conventional devices. Consists of. Therefore, these members are designed and assembled sequentially so as to have a shape corresponding to the vehicle (vehicle type) to which the air blowing device is attached and the positions in the vehicle (driver's seat periphery, passenger seat periphery and rear seat periphery, etc.) It is possible to manufacture an air blowing device having a shape corresponding to an arbitrary vehicle and a position in the vehicle. Hereinafter, for convenience, the vehicle and the position in the vehicle are collectively referred to as “vehicle or the like”.

  However, through the above-described manufacturing process, in order to manufacture the air blowing device, it is not only necessary to prepare a plurality of members using different dies for each vehicle, etc. It is necessary to assemble through the process. Therefore, in general, not only the number of members of the air blowing device to be prepared increases but the number of steps for assembling these members also increases as the types of vehicles to be handled increase. That is, the manufacture of the air blowing device becomes complicated as the types of vehicles to be handled increase even if the air blowing device having the same performance is manufactured.

  In view of the above problems, an object of the present invention is to provide an air blowing device for a vehicle that can be easily manufactured even when the types of vehicles to be handled increase.

  In order to solve the above problems, a vehicle air blowing device according to the present invention defines an air outlet and an “air outlet unit” including a wind direction adjusting plate and an air flow path. And a “support” that supports the air outlet unit so as not to be relatively movable.

  Specifically, the air outlet unit rotates around a square tube-like “frame” having the air outlet as an opening end, and a rotation axis orthogonal to the axis of the frame near the opening end. The “wind direction adjusting plate” is movably supported.

  Further, the frame body is configured to have “a pair of inner wall surfaces” parallel to the rotation axis of the wind direction adjusting plate. More specifically, the “pair of inner wall surfaces” is inclined in the vicinity of the opening end so as to approach the axis of the frame as it approaches the opening end.

  In addition, the support is a cylinder having the flow path as a hollow part, and has a “support part” for supporting the outlet unit on an inner wall surface of the cylinder. The air blowing device is configured to have an “attachment portion” for attaching the air blowing device to the vehicle interior portion on the outer wall surface.

  According to the above configuration, the “air outlet unit incorporating the wind direction adjusting plate” has a function as an air blowing device (for example, a function of adjusting the flow direction of the blown air flow), and “ A “support” having “an attachment portion for attaching the air blowing device to the vehicle interior portion” on the outer wall surface while being “supported so as not to be relatively movable” can be formed in a different shape for each vehicle or the like to be supported. In other words, it is possible to make the support body have a unique shape for each vehicle or the like while making the outlet unit a general-purpose shape. As a result, the number of members to be prepared can be reduced as compared with the case where all the members constituting the air blowing device are prepared for each vehicle to be handled.

  Further, since the air outlet adjustment unit has “wind direction adjusting plate built-in” (that is, a plurality of members are integrally formed in advance), the air outlet unit and the support body are simply assembled via the “support portion”. An air blowing device can be manufactured. As a result, the number of steps for manufacturing the air blowing device can be reduced as compared with a case where all the members constituting the air blowing device are individually assembled sequentially.

  In addition, since the air outlet unit is formed to provide a wind direction adjusting plate on the “rectangular cylindrical frame”, the rigidity of the air outlet unit is increased and the process of assembling the air outlet unit and the support itself is easy. It becomes.

  Therefore, the air blowing device according to the present invention has a configuration that can be easily manufactured even when the types of vehicles and the like to be handled increase.

  By the way, in the air blowing device of the present invention, the frame is “parallel to the rotation axis of the wind direction adjusting plate” and “is closer to the axis of the frame as it approaches the opening end in the vicinity of the opening end”. It has a pair of “inclined” inner walls. Therefore, the air which flows inside the frame toward the air outlet is collected toward the axis of the frame in the vicinity of the opening end. As a result, air is guided toward the wind direction adjusting plate provided “in the vicinity of the opening end”, so that the flow direction of the blown air flow can be adjusted efficiently by the wind direction adjusting plate (for example, See FIG. Further, for the same reason, it is possible to adjust the blown air flow without providing a large number of wind direction adjusting plates (for example, even if only one wind direction adjusting plate is provided on the axis of the frame). And can enhance the aesthetic appearance.

  Note that the expression “relatively impossible” means that the air outlet unit is fixed to the support to such an extent that the function as an air blowing device can be maintained. Relative movement due to play etc. that is provided automatically is not excluded. Further, the “frame body axis” represents a virtual straight line extending in the longitudinal direction through the inner center of the frame body (square tube shape).

  The configuration and effects of the vehicle air blowing device according to the present invention have been described above. Next, several modes (modes 1 to 3) of the air blowing device will be described below.

・ Mode 1
In the air blowing device of the present invention, the degree of inclination of the “pair of inner wall surfaces” of the frame body may be an appropriate magnitude in terms of adjusting the flow direction of the blown air flow, and the specific angle is particularly limited. Not.

For example, the frame is
In the case where the wind direction adjusting plate is rotatable within a range from the first position to the second position,
When the wind direction adjusting plate is in the “first position”, the wind direction adjusting plate and “one inner wall surface” of the pair of inner wall surfaces are parallel,
When the wind direction adjusting plate is in the “second position”, the wind direction adjusting plate and the “other inner wall surface” of the pair of inner wall surfaces may be configured in parallel.

  According to the above configuration, when the wind direction adjusting plate is at the first position (when the flow direction of the blown air flow is inclined most greatly), the air flow is rectified not only by the wind direction adjusting plate but also by one of the inner wall surfaces. Will be. Similarly, when the wind direction adjusting plate is in the second position, the air flow is rectified by both the wind direction adjusting plate and the other inner wall surface. As a result, the directivity of the blown air flow can be further increased.

・ Aspect 2
In the air blowing device of the present invention, from the viewpoint of manufacturing the air blowing device as simply as possible, it is preferable that a mechanism for rotating the wind direction adjusting plate (for example, various gears) is provided in the air outlet unit.

  Therefore, the air outlet unit may be configured to incorporate “all of the mechanisms for rotating the wind direction adjusting plate”.

・ Aspect 3
Furthermore, from the same viewpoint, it is preferable that only the support body has a function of attaching the air blowing device to the vehicle.

  Therefore, the support is configured to have a different shape corresponding to at least one of a vehicle to which the air blowing device is attached and a position in the vehicle, and the outlet unit is a vehicle to which the air blowing device is attached. And a predetermined shape that does not depend on any position in the vehicle.

  According to the said structure (mode 2, 3), since the versatility of a blower outlet unit further increases, even if it is a case where the kind of vehicle which should respond | corresponds increases, an air blowing apparatus can be manufactured still more easily.

It is a schematic perspective view which shows an example of embodiment of the air blowing apparatus of this invention. It is a disassembled perspective view of the air blowing apparatus shown in FIG. It is a schematic sectional drawing when the air blowing apparatus shown in FIG. 1 is cut | disconnected in parallel along an AA axis | shaft. It is a schematic sectional drawing when the air blowing apparatus shown in FIG. 1 is cut | disconnected by the plane along a BB axis | shaft.

  Hereinafter, an embodiment of an air blowing device of the present invention will be described with reference to the drawings.

  As shown in the schematic perspective view of FIG. 1, an air blowing device 10 (hereinafter referred to as “implementing device 10”) according to an example of an embodiment of the present invention has a cylindrical shape through which air can pass. ing.

  Hereinafter, for the sake of convenience, the directions toward the front and rear of the execution apparatus 10 along the axis AX of the execution apparatus 10 are referred to as “front direction F” and “rear direction B”. The directions going to are referred to as “upward direction U”, “downward direction D”, “left direction L”, and “right direction R”. These directions are based on the front, back, top and bottom and left and right directions when the execution device 10 is viewed from the vehicle operator when the execution device 10 is attached to the periphery of the instrument panel of the vehicle, Is defined.

  As shown by the arrow in the drawing, the execution device 10 directs the air flowing in from the opening portion 11 in the rear direction B in a direction determined by a plurality of wind direction adjusting plates 21 to 26 (details will be described later). It is configured to blow out from the opening 12 in the front direction F. Considering such a function of the implementation device 10, the opening 12 in the front direction F is hereinafter referred to as a “blower 12”. In addition, the shape of the blower outlet 12 is a rectangle whose left-right direction (LR) of the implementation apparatus 10 is a long side, and whose up-down direction (UD) is a short side.

  More specifically, as shown in the exploded perspective view of FIG. 2, the implementation device 10 includes a blowout unit 20 and a support 30.

  The air outlet unit 20 is an assembly (fin built-in ASSY) that defines the air air outlet 12 and includes the wind direction adjusting plates 21 to 26. Specifically, the air outlet unit 20 includes a rectangular cylindrical frame body 27 having the air outlet 12 as an opening end, and a wind direction rotatably supported by the frame body 27 in the vicinity of the opening end (air outlet 12). The adjustment plate 21 is slidably attached to the air direction adjustment plates 21 to 26 and the air direction adjustment plates 21 that are rotatably supported by the frame body 27 in the back direction B (the back side of the paper) than the air direction adjustment plate 21. The operation knob 28 is provided. In addition, it can be said that the wind direction adjusting plates 21 to 26 are “built in” that the wind direction adjusting plates 21 to 26 are supported inside the frame body 27.

  The wind direction adjusting plate 21 is a plate that can adjust the flow direction of air passing through the air outlet 12 in the vertical direction (UD), and has a substantially rectangular shape in plan view. The wind direction adjusting plate 21 is rotatable around a rotation shaft 21a (extending parallel to the longitudinal direction of the air outlet 12) perpendicular to the axis AX of the frame 27 (same as the axis AX of the execution device 10). ing. Specifically, as shown in the schematic cross-sectional view of FIG. 3 (A-A cross-sectional view of FIG. 1), the wind direction adjusting plate 21 is rotatable in the range from the first position P1 to the second position P2. ing.

  As shown in FIG. 3, the frame body 27 has a pair of inner wall surfaces 27 a and 27 b parallel to the rotation shaft 21 a of the airflow direction adjusting plate 21. The inner wall surface 27 a is an inner wall surface positioned in the upper direction U of the frame body 27, and the inner wall surface 27 b is an inner wall surface positioned in the lower direction D of the frame body 27. The inner wall surfaces 27a and 27b are inclined in the vicinity of the opening end (air outlet 12) so as to approach the axis AX of the frame 27 as the opening end (air outlet 12) is approached. Specifically, the wind direction adjusting plate 21 and the inner wall surface 27a are parallel when the wind direction adjusting plate 21 is at the first position P1, and the wind direction adjusting plate 21 and the inner wall surface when the wind direction adjusting plate 21 is at the second position P2. The inner wall surfaces 27a and 27b are inclined such that 27b is parallel to the inner wall 27b.

  3, in order to clarify the relationship between the inner wall surfaces 27a and 27b and the wind direction adjusting plate 21, when the wind direction adjusting plate 21 is at the first position P1 or the second position P2, only the wind direction adjusting plate 21 is used. It is represented by a broken line, and the illustration of the operation knob 23 is omitted (in practice, the wind direction adjusting plate 21 rotates together with the operation knob 28).

  The wind direction adjusting plates 22 to 26 are plates that can adjust the flow direction of the air passing through the air outlet 12 in the left and right directions (LR), and have a substantially rectangular shape in plan view (in FIG. 3). Only the wind direction adjusting plate 24 is displayed.). Specifically, as shown in the schematic cross-sectional view of FIG. 4 (BB cross-sectional view of FIG. 1), the wind direction adjusting plates 22 to 26 are rotating shafts 22a to 26a (which are orthogonal to the axis AX of the frame 27). It extends perpendicularly to the longitudinal direction of the outlet 12). Furthermore, the wind direction adjusting plates 22 to 26 are connected to the connecting member 29 via the connecting shafts 22b to 26b, and can be rotated in conjunction with each other. Of the wind direction adjusting plates 22 to 26, the wind direction adjusting plate 24 has a fan-shaped gear 24c composed of a plurality of teeth extending in the direction away from the rotation shaft 24a at the end in the front direction F.

  The operation knob 28 is a hollow plate having a substantially rectangular shape in plan view. The operation knob 28 includes a hollow portion extending in the longitudinal direction, and is attached (externally fitted) to the wind direction adjusting plate 21 so that the wind direction adjusting plate 21 passes through the hollow portion. Thereby, the operation knob 28 can slide parallel to the longitudinal direction of the wind direction adjusting plate 21. The operation knob 28 includes a plurality of teeth 28 a that protrude in the back direction B from the end in the back direction B. The plurality of tooth portions 28 a are engaged with a fan-shaped gear 24 c provided on the wind direction adjusting plate 24.

  By operating the operation knob 28, the flow direction of the air blown out from the air blowing device 11 is adjusted. More specifically, when the operator operates the operation knob 28 in the left direction L or the right direction R, a plurality of teeth 28 a provided in the operation knob 28 form a fan shape provided in the wind direction adjusting plate 24. The gear 24c is rotated around the rotation shaft 24a. As a result, the wind direction adjusting plate 24 and the other wind direction adjusting plates 22, 23, 25, 26 connected by the connecting member 29 rotate. As a result, the flow direction of the blown air flow changes in the left-right direction (LR).

  On the other hand, referring to FIG. 3 again, when the operator operates the operation knob 28 in the upward direction U or the downward direction D, the wind direction adjusting plate 21 rotates around the rotation axis 21a. As a result, the flow direction of the blown air flow changes in the vertical direction (U · D). At this time, since the inner wall surfaces 27a and 27b of the frame body 27 are inclined as described above, the air is guided toward the wind direction adjusting plate 21, rectified by the wind direction adjusting plate 21, and then the air direction adjusting plate 21. The air is blown out in a direction corresponding to the inclination (see the arrow in the figure).

  Thus, the blower outlet unit 20 of the implementation apparatus 10 incorporates all the mechanisms for rotating the wind direction adjusting plate 21 (and the other wind direction adjusting plates 22 to 26).

  When the wind direction adjusting plate 21 is at the first position P1, the wind direction adjusting plate 21 and the inner wall surface 27a are parallel to each other, so the inner wall surface 27a not only guides air toward the wind direction adjusting plate 21, The flow direction of the blown air flow is adjusted (directed toward the target flow direction) by the inner wall surface 27a itself. That is, when the wind direction adjusting plate 21 is in the first position P1, the air flow is rectified by both the wind direction adjusting plate 21 and the inner wall surface 27a. On the other hand, when the wind direction adjusting plate 21 is at the second position P2, the air flow direction is rectified by both the wind direction adjusting plate 21 and the inner wall surface 27b.

  Referring to FIG. 2 again, the support body 30 is a cylindrical body (retainer) that defines an air flow path and supports the air outlet unit 20 so as not to be relatively movable. Specifically, the support body 30 has a rectangular tube shape, and includes support portions 31 and 32 for supporting (fixing) the outlet unit 20 on the inner wall surface. It has attachment parts 33-35 for attaching the apparatus 10 to a vehicle interior part (for example, instrument panel periphery).

  The shape of the support 30 (including the arrangement and shape of the attachment portions 33 to 35) is designed corresponding to the vehicle or the like to which the execution device 10 is attached. Therefore, the shape of the support 30 has a shape (a shape satisfying a function as a jig; a shape unique to the vehicle) for each vehicle or the like to which the implementation device 10 is attached. On the other hand, the outlet unit 20 is attached to the vehicle or the like through the support 30 corresponding to the vehicle or the like in this way, and therefore has a shape independent of the vehicle or the like to which the implementation device 10 is attached (a function as an air blowing device is satisfied). Shape (general-purpose shape).

  Each of the outlet unit 20 and the support 30 is prepared independently of each other so as to have the above-described configurations. For example, the air outlet unit 20 integrally performs a series of processes of injection molding and assembly of each member (wind direction adjusting plates 21 to 26, frame body 27, operation knob 28, etc.) in a special mold. It can be prepared by a technique to be performed (so-called in-mold integrated assembly) or a technique in which each member is individually assembled after injection molding (normal assembly). On the other hand, the support 30 can be prepared by, for example, ordinary injection molding. And the implementation apparatus 10 is formed by assembling (connecting) the blower outlet unit 20 and the support body 30 which were prepared in that way.

  As described above, the execution device 10 is configured by the air outlet unit 20 that satisfies the function as the air blowing device and the support body 30 that satisfies the function as a jig for mounting on the vehicle. Even if the types of vehicles to be handled increase, it is possible to easily manufacture the vehicle.

<Other aspects>
The present invention is not limited to the above embodiment, and various modifications can be employed within the scope of the present invention.

  For example, in the implementation apparatus 10, the vertical adjustment of the blown air flow is performed by a single wind direction adjusting plate (wind direction adjusting plate 21). However, this adjustment does not necessarily need to be performed by one wind direction adjusting plate, and may be performed by two or more wind direction adjusting plates. However, from the viewpoint of downsizing the air blowing device and improving the aesthetic appearance, it is preferable that the number of the wind direction adjusting plates is as small as possible (for example, one wind direction adjusting plate is used).
