Description

  The present invention relates to a wind deflector device for an open car, and more particularly to an open car wind deflector device in which an opening for allowing a part of the wind to pass through the deflector is provided.

  Conventionally, it has been known that a wind deflector device for preventing wind-in wind during traveling is provided at the rear end of a cabin of an open car.

  This type of deflector device is of a type that completely blocks the flow of the wind with a transparent acrylic plate, etc., but with this type of completely blocked type, the pressure difference between the interior of the vehicle and the outside of the vehicle increases at high speeds. However, various air vortices are generated in the upper part of the passenger compartment due to the entanglement wind trying to get over the deflector, causing problems such as disturbing the passenger's hair, noisy abnormal noise and turbulence in the passenger compartment air. It was.

  Further, since it is transparent, there is a problem that the rear field of view deteriorates when the surface is scratched.

  Therefore, as shown in Patent Document 1 and Patent Document 2 below, by configuring the deflector with a net (net-like member), the pressure between the vehicle interior and the exterior of the vehicle during high-speed traveling is partially allowed to pass through the vehicle interior. There has been proposed a wind deflector device that prevents an increase in the difference and prevents the deterioration of the rear view.

JP-A-9-175192 Japanese Patent Publication No. 7-55624

  However, when the deflector is configured by a net as in Patent Document 1 and Patent Document 2, it is necessary to separately provide a frame member around the net in order to give a constant tension to the net, and the outer surface is a net. For this reason, there are problems such as deterioration over time, and even if a part is scratched, the entire surface is bent and a desired air flow cannot be obtained, or the appearance is deteriorated.

  Therefore, the present invention does not require a frame member separately as in the case of adopting a net in a wind deflector device for an open car, and further, the rear view is further improved while configuring the deflector with a member that does not easily deteriorate over time. An object of the present invention is to provide a wind deflector device for an open car that is improved.

  The wind deflector device for an open car according to the present invention is a wind deflector device arranged in the vehicle width direction at the rear end portion of the open car compartment, and includes a hard deflector plate that prevents entrainment wind, and the deflector plate includes A large number of holes having substantially the same shape that allow the passage of wind are formed in the vertical direction and the vehicle width direction, and each of the holes forms a staggered arrangement with adjacent holes.

  According to the said structure, a deflector is comprised with a hard board | plate material and many holes of the substantially same shape are formed in the stiff arrangement | positioning in the hard board | plate material.

  For this reason, a deflector can be comprised without requiring a frame member etc., and the blind spot of the rear view visible from a hole can be decreased by making many holes into a staggered arrangement.

  In other words, the rear view that the driver looks back or sees through the rearview mirror is wide in the horizontal direction, and the human view is expanded in the horizontal direction. The range can be reduced and the blind spot in the rear view can be reduced.

  Here, the member that forms the deflector plate may be, for example, a resin member, a metal member, a hard fiber member, a hard paper member, or the like, and is not particularly limited as long as it has more rigidity than the net member. .

  Further, the color and the like may be black, transparent, translucent, metallic color, and the like, and are not particularly limited.

  Furthermore, the staggered arrangement is also 90 degrees staggered in relation to adjacent holes (a staggered arrangement in which the angle between two adjacent holes is 90 degrees), 60 degrees staggered (similarly, the angle is 60 degrees). A certain staggered arrangement) is conceivable and is not particularly limited.

  In one embodiment of the present invention, the deflector plate is formed of a non-transparent member.

  According to the above configuration, the deflector plate is formed of a member that is not transparent.

  For this reason, even if the surface of the deflector plate is scratched, it is less noticeable and non-transparent, so that the rear view ensuring by the hole functions more effectively.

  Therefore, the effect of the present invention can be obtained more effectively without causing the problem of deterioration of the rear field of view due to the occurrence of scratches or the like.

  In one embodiment of the present invention, in the staggered arrangement, an angle formed by one of the holes and two holes adjacent to the holes is set to approximately 60 degrees.

  According to the said structure, the space | interval of zigzag arrangement | positioning of a hole part will be about 60 degree | times, and the space | interval of each hole part will become equal.

  For this reason, unlike the 90-degree staggered arrangement, the distance between the holes is not uneven, and the rear view from the holes can be improved efficiently.

  Therefore, the visibility from a hole can be improved efficiently.

  In one embodiment of the present invention, the deflector plate is a resin member injection-molded with a resin material, and the hole is circular.

  According to the above configuration, the deflector plate is injection-molded with a resin material. However, since the hole is circular, the resin flow around the hole can be improved.

  Therefore, the product defect of the deflector board which forms many holes can be reduced, and productivity can be improved.

  In one embodiment of the present invention, the hole is a horizontally long hole extending in the horizontal direction.

  According to the above configuration, the hole portion of the deflector plate opens horizontally in the horizontal direction.

  Since the deflector plate has a predetermined thickness unlike a thin net, the view through the hole is narrowed by being blocked by the inner wall of the hole when viewed from an angle rather than directly in front of the hole. By opening the hole horizontally long, it is possible to widen the horizontal visual recognition area, and even when the driver or the like is seen from an obliquely forward position of the deflector plate, the rear can be surely visually recognized.

  Therefore, the line of sight when viewed from an oblique front of the deflector plate can be significantly improved.

  In one embodiment of the present invention, the hole has a diameter of the opening on the surface of the deflector plate larger than the diameter of the central portion in the thickness direction of the deflector plate.

  According to the said structure, a hole part is penetrated and formed in a substantially drum shape with respect to a deflector board.

  For this reason, although the angle which visually recognizes the back through a deflector board can be enlarged, the hole diameter which penetrates does not become large too much.

  Therefore, the wind transmittance of the deflector plate can be maintained at an appropriate value while improving the rear visibility. Further, when the deflector plate is resin-molded, the mold can be easily removed from the mold.

  In one embodiment of the present invention, a rigid frame portion is integrally formed around the deflector plate.

  According to the above configuration, the rigid frame portion is integrally formed around the deflector plate.

  For this reason, it is not necessary to ensure rigidity only by the deflector plate in which many holes are formed, by ensuring the rigidity that can withstand the wind pressure of the wind that is entrained by the frame portion.

  Therefore, the thickness of the deflector plate can be made as thin as possible, and the visibility from the oblique front of the deflector plate can be improved without enlarging the opening of the hole.

  In one embodiment of the present invention, a separate frame member corresponding to the frame portion of the deflector plate is provided.

  According to the above configuration, a separate frame member is provided separately from the frame portion of the deflector plate.

  Therefore, the rigidity around the deflector plate can be further increased. In addition, since the “frame” of the deflector plate is configured by the frame portion and the frame member, in the case of resin molding, the decorative surface can be made outside and the appearance can be improved. Furthermore, since it can be composed of two parts rather than a three-part structure in which a single deflector plate is sandwiched between front and rear frame members, it can be produced at low cost.

  In one embodiment of the present invention, the deflector plate is made of polypropylene, the plate thickness is set to about 3 mm, and the holes are set to a staggered arrangement of about 60 degrees with a hole diameter of about 3 mm and a hole center distance of about 6 mm. Is.

  According to the above configuration, the highest performance is obtained when considering the wind permeability and rear visibility as a deflector plate actually installed in an open car, and the resin fluidity and defect occurrence rate as a resin molded part. can do.

  According to the present invention, a deflector can be configured without the need for a frame member or the like, and the blind spots in the rear view visible from the holes can be reduced by arranging a large number of holes in a staggered arrangement. .

  Therefore, in a wind deflector device for an open car, a frame member is not required separately as in the case of adopting a net, and the deflector is configured with a member that does not easily deteriorate over time, and the rear view is further improved. Can do.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a side view of an open car V employing the wind deflector device of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a front perspective view of the wind deflector device installed at the center of the rear end of the passenger compartment.

  As shown in FIG. 1, the wind deflector device 1 of the present invention is installed at the rear end of a passenger compartment C behind the seat 2 of the open car V so as to protrude above the so-called belt line B, so as to run in an open state. Inside, as shown by the arrows, the wind W that is caught from the rear side of the vehicle is prevented, and the wind W is prevented from being caught in the passenger compartment C.

  However, when traveling at high speed, the flow velocity increases, the pressure difference between the interior of the passenger compartment C and the exterior of the passenger compartment increases, and this is caused by the wind going over the wind deflector device 1 from the rear side of the vehicle toward the passenger compartment C. In addition, an air vortex or the like is generated above the passenger compartment C, and noise or air suction may occur.

  Therefore, in the present embodiment, the deflector plate 3 of the wind deflector device 1 is provided with a plurality of minute holes 4 to be described later, and a part of the entrainment air W is introduced into the passenger compartment C ( Arrow shown by a broken line in FIG. 1).

  As a result, an increase in the pressure difference between the inside of the passenger compartment C and the outside of the vehicle during high-speed traveling is mitigated to prevent the occurrence of air vortices and the like.

  For this reason, the driver D and the like can enjoy a comfortable drive even when traveling at high speed.

  As shown in FIGS. 2 and 3, the wind deflector device 1 is installed at the upper end of the back trim 6 between the left and right roll bars 5, 5 installed behind the seat 2. The wind that is caught in the passenger compartment C from 5 is blocked.

  By installing at this position, the wind is cut off at the place where the wind is most likely to enter. Therefore, even if the deflector plate 3 is not so large, the entrainment wind can be effectively cut off.

  In this embodiment, the deflector plate 3 is provided only in the lower half of the position between the roll bars 5 and 5, but it extends to the upper side between the roll bars 5 and 5 so May be prevented.

  Further, a deflector plate may be additionally installed in the space R (see FIG. 3) surrounded by the roll bars 5 and 5, or a single deflector plate may be installed over the entire width in the vehicle width direction. The amount of wind involved may be further reduced.

  The specific structure of the wind deflector device 1 will be described in detail with reference to FIGS.

  4A is a plan view of the wind deflector device 1 as viewed from above, FIG. 4B is a front view of the wind deflector device 1 as viewed from the front, and FIG. 5 is a view taken along line AA in FIG. 6 is a cross-sectional view taken along the line BB in FIG. 4B, and FIG. 7 is a cross-sectional view taken along the line CC in FIG. 4B. 5 to 7, the hole 4 is omitted in order to eliminate complexity.

  The wind deflector device 1 of this embodiment includes a substantially rectangular base 7 extending in the vehicle width direction, a deflector plate 3 standing on the base 7 so as to extend in the vehicle width direction and the vertical direction, and the deflector plate 3. And a hinge mechanism 8 that is hinged to the pedestal 7 so as to be undulating.

  The above-described pedestal 7 is composed of a rectangular lid member having leg portions 71 that contact the back trim 6 at the periphery, and covers the hinge mechanism 8 and the like, which will be described later, from above when installed in the open car V. I try to hide it.

  Two rectangular opening holes 72 and 72 are provided at the left and right positions in the vehicle width direction of the pedestal 7, and the deflector plate 3 is linked to the hinge mechanism 8 through the opening holes 72 and 72.

  The aforementioned deflector plate 3 is formed by injection-molding polypropylene resin, and is disposed so as to overlap the substantially trapezoidal main body member 31 whose upper edge is longer than the lower edge, and the rear outer peripheral edge of the main body member. And a frame member 32 to be configured.

  The main body member 31 is provided with a frame portion 31a having a U-shaped cross section that protrudes forward at the outer peripheral edge, and a windproof surface 31b that forms a plurality of holes 4 to be described later. By providing the frame portion 31a on the outer peripheral edge in this manner, the rigidity of the main body member 31 can be increased, and even if the windproof surface 31b is thin, the main body member 31 alone can ensure sufficient rigidity to withstand wind pressure. can do.

  Further, at the lower part of the main body member 31, cover parts 31 c and 31 c covering the hinge mechanism 8 are formed one by one on the left and right.

  On the other hand, the frame member 32 is configured by an annular member having a U-shaped cross section that protrudes rearward at a position corresponding to the frame portion 31 a of the main body member 31, and the frame portion so as to surround the windproof surface 31 b of the main body member 31. It joins to the back side (vehicle rear side) of 31a.

  Thus, a closed cross section is formed between the frame member 32 and the frame portion 31a of the main body member 31, and the rigidity of the outer peripheral edge of the deflector plate 3 is further increased.

  In addition, as described above, the frame member 32 is also formed by injection-molding polypropylene resin in the same manner as the main body member 31. However, the frame portion 31a and the frame member 32 are set by setting the respective decorative surfaces outward. The appearance of the surface of the “frame” composed of can be improved.

  The hinge mechanism 8 includes a rotating body 81 (see FIG. 5) that is fastened and fixed to the lower end portion of the deflector plate 3, and a hinge case 82 that guides and holds the rotating position of the rotating body 81.

  The rotating body 81 is formed of a member having a substantially U-shaped cross section, and has convex portions 83 serving as a rotation center on both sides of the central bent portion 81a. The projecting portion 83 is pivotally supported by the boss portion 84 of the hinge case 82 (see FIG. 6), so that the rotating body 81 is rotatable with respect to the hinge case 82.

  As shown in FIG. 5, by rotating the deflector plate 3 so as to lie down on the front side of the vehicle (the left side in the drawing is the front side of the vehicle), the rotating body 81 is also rotated on the rear side of the vehicle.

  A detent member 85 urged in the off-axis direction is provided at the tip of the rotating body 81. The rotating body 81 is positioned by fitting the detent member 85 into fitting holes 86 and 87 provided in the hinge case 82.

  Further, the detent member 85 has a function of giving moderation to the rotation operation of the deflector plate 3, and the detent member 85 has a detent in the fitting holes 86 and 87 at positions corresponding to the standing position and the lying position of the deflector plate 3. By engaging and disengaging the member 85, a “crisp” feeling of moderation is generated.

  On the other hand, the hinge case 82 is formed with a fan-shaped cross-section guide portion 88 for positioning and guiding the detent member 85 at the center as described above, and on the boss portion on the lower surface of the base 7 as shown in FIG. On the other hand, it has a fixing portion 89 that is fastened and fixed by a fastening bolt, and a pair of front and rear fasteners 90, 90 that are inserted into and fixed to the back trim 6 as shown in FIG.

  Thus, the hinge case 82 fixes the hinge mechanism 8 to the pedestal 7 by being fixed to the pedestal 7 by the fixing portion while defining the rotation position of the rotating body 81 at the central guide portion. Thereby, the deflector plate 3, the hinge mechanism 8, and the base 7 are integrated (sub-assembled state).

  After the integration as described above, the wind deflector device 1 is attached to the open car V by inserting and fixing the fasteners 90, 90 into the opening holes 61, 61 opened at the upper end of the back trim 6 (see FIG. 7). Will be installed.

  Next, the detailed structure of the hole provided in the windproof surface of the deflector plate will be described with reference to FIGS. 8 is a detailed view of the holes 4 provided in the windproof surface 31b, FIG. 9 is a cross-sectional view of the holes 4 corresponding to the cross-sectional view taken along the line DD in FIG. 8, and FIG. 10 is a parallel arrangement (A). It is explanatory drawing of a comparison of zigzag arrangement | positioning (B).

  As shown in FIG. 8, the holes 4 in this embodiment are arranged in a staggered arrangement of 60 degrees with the holes 4 being set at intervals of 60 degrees, and the intervals between the holes 4 are made uniform. Yes.

  Thus, the rear visual field visually recognized through the holes 4 can be improved by arranging the plurality of holes 4 in a staggered arrangement.

  That is, as shown in FIG. 10, for example, when holes 4 having the same pitch P and the same diameter D are provided, and when arranged in parallel as shown in FIG. However, in the case of a staggered arrangement as shown in (B), since the vertical width (interval S ′) can be made shorter than the interval S, the horizontal blind angle can be reduced. Can do. The rear view that the driver looks back or sees with the rearview mirror is wide in the horizontal direction (to see other vehicles and obstacles on the road), and generally the human field of view spreads in the horizontal direction. By reducing the blind spot in the horizontal direction through the plate 3, the rear field of view can be improved.

  Moreover, by setting it as 60 degree staggered arrangement | positioning, the space | interval of all the hole parts 4 ... can be made equal.

  Thus, since the holes 4 can be opened most efficiently by equalizing the intervals between the holes 4, the rear view can be improved efficiently. Moreover, since the space | interval of the hole part 4 ... is equal, also when inject-molding, a resin flow can be made uniform and the defect rate of a product can be reduced.

  Furthermore, regarding injection molding, since the shape of the hole 4 is circular, the resin flow around the hole 4 can be made smooth, and product defects can be further reduced.

  Further, as shown in FIG. 9, the through-hole shape of the hole 4 has a predetermined inclination angle α so that the diameter d1 of the central portion of the plate thickness t is the smallest and the diameter d2 of the opening on both side surfaces is the largest. It has a substantially drum shape.

  Thus, the rear view from the hole 4 can be further improved by forming the hole 4 in a substantially drum shape.

  That is, as shown in FIG. 2, the driver D is positioned obliquely forward in the horizontal direction with respect to the wind deflector device 1, so that the deflector plate 3 is viewed from obliquely forward. In this case, Since the hole 4 has a substantially drum shape, the rear can be visually recognized through the hole 4 without looking from the front (the line of sight indicated by the arrow in FIG. 9), and the visibility of the rear view is increased. Can do it.

  In addition, since it has a substantially drum shape as described above, when it is released from the mold, it is possible to easily release the mold and to obtain an effect that the defectiveness of the product can be reduced. .

  Further, an orifice portion 41 having a predetermined curvature R is provided over the entire circumference of the hole portion 4 between the hole portion 4 and the windproof surface 31b surface.

  By providing the orifice portion 41, the wind (air flow) passing through the hole portion 4 can be rectified, and abnormal noise caused by various minute air vortices can be suppressed.

  The deflector plate 3 (windproof surface 31b) of this embodiment has a plate thickness t of 3 mm, a diameter d1 (diameter of the central portion) of the holes 4... 3 mm, and a hole center distance (p in FIG. 8) of 6 mm. The aperture ratio is set to 22.6%, the inclination angle α of the hole portion 4 is set to 11.3 °, and the curvature R of the orifice portion 41 is set to 0.9 mm.

  Thus, by setting, when actually installed in the open car V, the passing flow rate of the entrainment air can be made appropriate, the rear view can be made as good as possible, and further, the product defect at the time of injection molding can be reduced. Occurrence can be reduced, and in addition, abnormal noise can be reduced.

  In addition, since the deflector plate 3 of this embodiment is formed of black polypropylene resin, even if the surface is slightly scratched, the scratch is not noticeable, and the rear field of view is similar to an acrylic plate. Since it does not change depending on the number of scratches, the rear visibility can be secured stably.

  The main body member 31 is injection-molded as described above, and an abutment position e (portion indicated by a broken line circle in FIG. 8) of an ejector pin (projection pin) (not shown) at this time is windproof. It is set to an intermediate portion of the three holes 4 on the surface 31b.

  This position is a position that does not interfere with the orifice portion 41 described above, and by setting this position, all the tip surfaces of the ejector pins can be brought into contact with the wind-proof surface 31b evenly.

  Thereby, the curvature shape of the orifice part 41 can also be maintained, and since generation | occurrence | production of a burr | flash etc. can be prevented, the appearance as a product can also be improved.

  In particular, in the deflector plate 3 of the present embodiment, the surface on which the ejector pin abuts (the vehicle rear side surface) is also exposed to the outside. Can be prevented.

  FIG. 11 shows the contact position e of the ejector pin in the entire deflector plate 3. As shown in this figure, the plurality of ejector pins abut on the deflector plate 3 as uniformly as possible in order to abut in the staggered arrangement positions in a plurality of rows in the width direction (dashed circles). A portion e ...).

  As a result, the entire body member 31 is evenly released from the molding die, the occurrence of product defects can be reduced, the shape of the holes 4 is stable, and there is no occurrence of burrs. Can be directly exposed to the outside.

  Moreover, in this embodiment, since the deflector plate 3 is composed of two parts of the main body member 31 and the frame member 32, a three-part structure in which one deflector plate 3 is sandwiched between the front and rear frame members 32 is used. And production costs can be reduced.

  Next, the structure of the holes 4 of the deflector plate 3 in another embodiment will be described in detail with reference to FIGS.

  First, (a) is configured such that the holes 104... Are formed in a horizontally long shape extending in the horizontal direction, and the holes 104.

  As described above, when the holes 104 are provided, the holes 104 are opened in the horizontal direction larger than the holes 4 in the above-described embodiment. The viewing area can be expanded.

  Therefore, the horizontal rear view from the driver D can be further expanded, and the visibility can be improved.

  Next, (b) has a structure in which the holes 204 are arranged in a 90-degree staggered arrangement in which the angle formed by the two adjacent holes 204 is 90 degrees.

  As described above, when the holes 204 are arranged in a 90-degree staggered arrangement, the blind spot range in the horizontal direction can be reduced as compared with the parallel arrangement (see FIG. 10A). Can be spread.

  Therefore, also in this case, the visibility can be improved.

  Finally, (2) is a structure in which the holes 304 are square and the holes 304 are staggered.

  As described above, when the shape of the hole 304 is square, when the diameter is the same (length), it is possible to secure a larger opening area than the circular shape, thereby further improving the rear view. it can.

  Therefore, also in this case, the visibility can be improved.

  In addition, about another effect, it is the same as that of the above-mentioned embodiment.

  In addition to these, the shape of the hole may be a hexagon, an octagon, a cross, or the like. Even if these holes are arranged in a staggered manner, the area that becomes a blind spot in the horizontal direction can be reduced as compared with the parallel arrangement, so that the visibility of the rear view can be improved.

As described above, in the correspondence between the configuration of the present invention and the above-described embodiment,
The deflector plate of the present invention corresponds to the main body member 31 of the embodiment,
The present invention is not limited to the above-described embodiment. For example, the deflector plate 3 may be formed of a resin other than polypropylene resin, and may be a metal member, a hard fiber member, a hard paper member, a glass member, or the like. You may comprise with a member more rigid than a net-like member.

  Further, the color or the like of the deflector plate 3 may be white, transparent, or translucent.

  Further, a three-part structure in which one deflector plate is sandwiched between front and rear frame members may be employed.
