Description

[Detailed Description of the Invention] Industrial application The present invention relates to an air spoiler for vehicles, and in particular, receives rainwater flowing along the roof to prevent it from flowing to the side of the vehicle and preventing the rainwater from flowing onto the back windshield. The present invention relates to an air spoiler for a vehicle, which can improve rear visibility during traveling and prevent rainwater from flowing into a room even if the vehicle is traveling with the back window open in case of rain.

2. Description of the Related Art A conventional air spoiler 1 is shown in FIG.
Is simply fixed to the roof panel 8 above the back window glass 6 by the bolts 4 and the nuts 5 via the bracket 3, and the air flowing along the roof panel 8 in the direction of the arrow A is moved downward by the straightening plate 2. It was bent and flowed in the direction of the arrow B along the back window glass 6 to blow away dust and mist (not shown) rolling up from the rear of the vehicle.

However, according to the air spoiler, the rainwater 9 flowing in the direction of arrow C on the roof panel 8 flows backward as it is and flows on the back windshield 6 (direction of arrow D), which may obstruct the rear view. Further, the flow of this rainwater may be increased by the air flow in the direction of arrow B by the air spoiler 1, and there was room for improvement.

Further, if the vehicle 10 is inadvertently shaken while the back windshield 6 is open, or if the vehicle travels in the rain, rainwater 9 may flow into the room (in the direction of arrow E) and wet the room inadvertently.

Further, since the straightening vanes 2 are only fixed to the vehicle 10 in one row by the two or three brackets 3 arranged in a straight line, there is a problem that the mounting strength is weak.

Further, Japanese Utility Model Application Laid-Open No. 63-122164 discloses a back door structure for an automobile, but the conventional example does not relate to an air spoiler of a type that is provided independently of the vehicle body and protrudes above the roof panel of the automobile. The structure of the back door itself is completely different from that of the present invention. That is, although rainwater is caused to flow laterally so as not to flow into the windshield of the back door, the roof panel is recessed downward to form a groove-like rain rail. However, this may hinder rearward visibility as a result of rainwater jumping over the entrance to this groove and flowing from the air inlet to the windshield while the vehicle is running.
Also, even if you want to clean the groove, you can not get in the state where the back door is closed, you can get it only when you flip up the back door upward, but it is still difficult to clean, mud and scale mixed with rainwater, Moss accumulates in the ditch for a long time and obstructs the flow of rainwater, which causes water pools and deteriorates the rubber of the weatherstrip, resulting in corrosion of the rain rail and water leakage into the vehicle. There was a risk of causing it. Further, the conventional example does not disclose any improvement in the mounting strength of an independent air spoiler.

In Japanese Utility Model Application Laid-Open No. 63-102584, a vehicle body structure is disclosed. The conventional example relates to a front window,
Moreover, the projections for flowing the rainwater to the side are provided in a portion substantially integrated with the roof panel (in the specification, described as "lower rear end of the deflector"). It's not about an independent air spoiler. Further, although measures against rainwater have been disclosed, no positional relationship and mounting relationship with respect to the roof as disclosed in the present application are disclosed. That is, there is no disclosure of a configuration in which a rain gutter is provided at a position in front of the air spoiler or a configuration in which the rain gutter is integrally attached to the air spoiler on the roof panel. Therefore, the configuration of the conventional example is completely different from that of the present invention.

The present invention was made in order to eliminate the above-mentioned drawbacks of the prior art. The purpose of the present invention is to provide a rain gutter formed integrally with the straightening vane and in front of the straightening vane above the back windshield. It is fixed to the roof panel of the vehicle so that rainwater flowing along the roof can be received and discharged to both sides of the vehicle, and this also inadvertently leaves the back windshield open and keeps the vehicle open while stopped. It is to prevent rainwater from flowing into the room even when it is shaken or when it is running in the rain.

Another purpose is to fix the vehicle air spoiler to the roof panel above the back windshield in two rows in the front-rear direction of the vehicle by using a plurality of bolts which are fixed in parallel to the straightening vane and the rain gutter in parallel with each other in the front-rear direction. This increases the attachment strength of the air spoiler.

SUMMARY In summary, the present invention (Claim 1) includes a straightening plate fixed to a roof panel above the back windshield so that an air flow flowing along the roof of the vehicle flows downward along the back windshield, and It is formed integrally with the straightening vane and in front of the straightening vane so as to receive the rainwater flowing along the roof and flow it to the side of the vehicle to prevent the rainwater from flowing on the back windshield. A rain gutter configured to be in close contact with the roof panel is provided.

Further, the present invention (claim 2) provides a straightening plate configured to allow an air flow flowing along the roof of the vehicle to flow downward along the back windshield, and rainwater flowing along the roof to receive the rainwater. A rain gutter formed integrally with the straightening vane and in front of the straightening vane so as to prevent the rainwater from flowing laterally to flow into the back windshield, and the straightening vane and the rain gutter are provided. A plurality of bolts arranged in two rows in the front-rear direction of the vehicle are fixed, and the straightening plate and the rain gutter are fixed to the roof panel above the back window glass by the plurality of bolts, respectively. It is characterized by having done.

The present invention will be described below based on the embodiments shown in the drawings. The vehicle air spoiler 11 according to the present invention includes a current plate 12 and a rain gutter 13 in FIGS. 1 and 2.

The straightening vane 12 is provided with an arrow F along the roof panel 15 of the vehicle 14.
The flow of air flowing in the direction is bent in the direction of the arrow G to flow downward along the back window glass 16 to blow away dust and mist (not shown) that the vehicle 14 winds up in the rear. It is composed of a rectifying body 12a having a length substantially equal to the width of 14 and having a D-shaped cross section, and a plurality of ribs 12b formed integrally with the rectifying body.

Further, a plurality of brackets 18 for fixing the rectifying plate to the roof panel 15 are fixed to the rectifying plate 12 with screws 19, and a bolt 20 fixed to the bracket by means such as welding is installed above the back window glass 16. The washer 21 and the nut 22 are fixed to the roof panel 15 to fix the flow regulating plate 12 at a position separated from the roof panel 15 by a predetermined dimension.
An air introduction port 23 for letting in air is formed between the roof panel 15 and the current plate 12.

The rain gutter 13 receives the rainwater 24 flowing on the roof panel 15 in the direction of the arrow H to the side of the vehicle 14 (direction of the arrow I).
Is formed into a plate shape having substantially the same length as the width of the vehicle 14, and is continuous with the rib 12b integrally with the straightening vane 12 and in front of the straightening vane, for example, a composite. Manufactured by integral molding of resin.

The front side surface 13a of the rain gutter 13 may have a concave shape so as to easily receive the rainwater 24 as shown in FIG. 2 or a flat surface as shown in FIG. 3 (another embodiment). You can leave it. Also, bolts to the rain gutter 13
25 is fixed by means such as insert molding.

Then, the rain gutter 13 is closely attached to the roof panel 15 above the back windshield 16 and is fixed by the washer 26 and the nut 28. As a result, the air spoiler 11 is fixed to the roof panel 15
It will be fixed in two rows in the longitudinal direction of the vehicle.

Operation The present invention is configured as described above, and its operation will be described below. 1 to 3, the vehicle
When the vehicle 14 travels, the air in front of the vehicle will move to the side 14 of the vehicle 14.
Flows in the direction of arrow F along a and the roof panel 15. Then, the air flow along the roof panel 15 flows in from the air introduction port 23 and is guided by the rectifying body 12a to change the flow direction to the direction of the arrow G and flows downward toward the back window glass 16, and the back window glass Flowing along. The air flow (in the direction of arrow G) blows off dust or mist that winds up behind the vehicle 14 to prevent the dust or mist from adhering to the back windshield 16.

On the other hand, the rainwater 24 that has fallen on the roof panel 15 flows in the direction of arrow H on the roof panel due to the inertial force and the force of the air flow in the direction of arrow F. Then, when the rainwater reaches the position of the rain gutter 13, the rain water 24 becomes the front side surface 13a of the rain gutter 13.
As a result, the flow of the rainwater in the direction of arrow H is blocked, so that the rainwater changes its flow direction to the direction of arrow I and is guided to both side surfaces 14a of the vehicle 14 and flows down along the side surface.

At this time, the rain gutter 13 is fixed to the roof panel 15 so as to be closely attached to the roof panel 15 without any gaps, so that the rain water 24 is rain guttered.
It does not flow to the back windshield 16 side below 13, and even if the driver inadvertently runs with the back windshield 16 open during rainy weather, or even shakes the vehicle while the vehicle is stopped, The rainwater 24 does not flow into the vehicle to pollute or wet the interior.

Further, not only the rainwater 24 does not flow on the back windshield 16, but the rainwater 24 that has fallen on the back windshield 16 is blown away by the air flow in the direction of arrow G, so the back windshield 16 is always kept clean. It is possible to secure a sufficient backward view by leaning.

Further, a wind pressure of a magnitude corresponding to the traveling speed is applied to the straightening vane 12 by the air flow, but the vehicle air spoiler 11 is arranged on two straight lines separated from each other in the front-rear direction of the straightening vane 12 and the rain gutter 13. Since it is fixed to the roof panel 15 in two rows with a plurality of bolts, the mounting strength is great and the current plate
No looseness of 12 or loosening of bolts 20 and 25 will occur. Further, since the bracket 18, the rib 12b and the bolts 20 and 25 can be made small, the degree of freedom in designing the shape of the vehicle air spoiler 11 is improved and the shape can be freely set.

Effect Since the present invention fixes the rain gutter integrally formed with the current plate to the roof panel above the back windshield as described above, it can receive rainwater flowing along the roof and flow it to both sides of the vehicle. As a result, there is an effect that it is possible to prevent rainwater from flowing into the room even if the vehicle is shaken while the car is stopped or the vehicle is running in the rain, while the back windshield is inadvertently opened.

Also, the vehicle air spoiler is fixed to the roof panel above the back windshield in two rows using a plurality of bolts that are fixed to the straightening plate and the rain gutter in parallel in the front-rear direction, increasing the attachment strength of the air spoiler. There is an effect that can be.
