Description

  The present invention relates to a slide door that opens rearward so as to open and close the entrance opening on the side of the vehicle body, and a slide door rail that is attached to the vehicle body side wall on the rear side of the entrance opening and that supports the slide door slidably. And a slide door rail cover structure for a vehicle including a cover member that covers the slide door rail from the outside of the vehicle.

  When the vehicle is traveling, a negative pressure region is generated on the rear side of the vehicle body due to the airflow around the vehicle body, and the airflow in the lower part of the vehicle body is sucked toward the negative pressure region, so that the rear end surface of the vehicle body from near the ground surface. It is known that upward airflow is generated along For this reason, when the vehicle travels in rainy weather or the like, dirt such as muddy water and rainwater that is scattered with the rotation of the rear wheels is rolled up together with the rising air current and adheres to the rear end surface of the vehicle body.

As an apparatus for preventing such a phenomenon, for example, a drooping up prevention apparatus disclosed in Patent Document 1 below is known. Specifically, the drooping up prevention device of Patent Document 1 includes an air intake port provided at a front end portion of a trunk lid, an air outlet provided at a rear end surface of the trunk lid, and these air intake ports. And an air passage that is arranged along the inner side surface (back surface) of the trunk lid as a member that connects between the air outlets. When the vehicle is running, air taken in from the air intake port is blown out from the air outlet on the downstream side through the air passage, and negative air generated on the rear side of the vehicle body by the blown-out air. By reducing the force of the pressure region, the adhesion of dirt such as muddy or rain water to the rear end surface of the trunk lid and the like is suppressed.
JP-A-8-58635

  However, in the configuration of the above-mentioned Patent Document 1, since the anti-dripping device composed of a duct-like member is provided along the inner side surface of the trunk lid, the volume in the trunk (loading space) is caused by the presence of the device. ) Is narrowed.

  Accordingly, the inventors of the present application pay attention to the case where the side door provided on the side surface portion of the vehicle body is a slide door that opens rearward, and a structure such as a cover that covers the guide rail (slide door rail) for the slide door from the outside of the vehicle. I thought that it would be possible to suppress the adhesion of slag, rainwater, etc. without narrowing the interior space such as the luggage compartment.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle sliding door rail cover structure capable of effectively suppressing dirt at the rear of the vehicle body without narrowing the interior space of the vehicle. And

  In order to solve the above-described problems, the present invention provides a slide door that opens rearward so as to open and close the opening for getting on and off the side of the vehicle body, and is mounted on the vehicle body side wall on the rear side of the opening for getting on and off the slide. A sliding door rail cover structure for a vehicle comprising a sliding door rail that slidably supports a door and a cover member that covers the sliding door rail from the outside of the vehicle, and for taking in air from the outside during traveling of the vehicle An opening is provided in the front portion of the cover member, and a flow portion extending in the front-rear direction in which air taken in from the air intake port can flow between the outer wall of the cover member and the mounting portion of the slide door rail. An air outlet for blowing out the air introduced into the circulation part is provided at a predetermined part of the rear part of the vehicle body that is provided on the downstream side of the circulation part. It is characterized in that (claim 1).

  According to the present invention, when the vehicle travels, air is taken in from the outside through the air intake port provided in the front part of the cover member for shielding the sliding door rail, and the taken-in air is passed to a predetermined part at the rear part of the vehicle body. Since the air is blown out from the provided air outlet, the pressure drop in the negative pressure region generated on the rear side of the vehicle body can be suppressed by the blowout flow, and can be attracted to the negative pressure region. Thus, there is an advantage that it is possible to effectively suppress the dirt such as mushrooms and rainwater that are wound up from adhering to the rear part of the vehicle body.

  In addition, since a space between the mounting portion of the slide door rail and the outer wall of the cover member that covers this from the outside of the vehicle is used, a circulation portion that circulates the air taken in from the air intake port downstream is formed. In a very rational configuration using the space necessary for the vehicle body structure, it can take in the air during driving and blow it out to the rear side of the vehicle body, without reducing the interior space of the vehicle body in the rainy weather etc. There is an advantage that dirt can be effectively suppressed.

  Preferably, the cover member is formed of a hollow member having a closed cross-sectional space inside, and the flow passage portion is formed by the closed cross-sectional space in the cover member.

  According to this configuration, by forming the closed cross-sectional space inside the cover member, the rigidity can be effectively improved, and the above air can be used by using the circulation portion including such a closed cross-sectional space. Since the air taken in from the intake port can be sent to the downstream side without leakage, the flow rate of the air blown out from the air outlet can be secured sufficiently, and dirt on the rear of the vehicle body in the rainy weather etc. There is an advantage that it can be effectively suppressed.

  It is preferable that the predetermined part of the rear part of the vehicle body where the air outlet is provided includes a peripheral part of the tail lamp.

  According to this configuration, it is possible to prevent the tail lamp from being contaminated when it rains, so that it is possible to prevent the light display by the tail lamp from becoming difficult for the driver of the following vehicle to see, and the safety of the vehicle when it rains. There is an advantage that can be improved effectively.

  It is also preferable that the predetermined part of the rear part of the vehicle body where the air outlet is provided includes a peripheral part of the rear gate.

  According to this configuration, it is possible to prevent dirt from adhering to the rear gate during rainy weather, etc., so that it is possible to effectively prevent the passenger's hand that opens and closes the rear gate from becoming dirty, and the usability of the rear gate during rainy weather is further improved. There is an advantage that can be made.

  In the case where the rear gate has a rear window, it is preferable that at least a part of the air blown out from the air outlet is configured to flow toward the installation portion of the rear window.

  According to this configuration, there is an advantage that dirt can be effectively prevented from adhering to the rear window during rainy weather, and the view (rear view) facing from the inside of the vehicle through the rear window can be favorably secured.

  The cover member may be provided in a state of projecting to the vehicle outer side from a line continuously connecting the members positioned above and below, and in this case, the front end of the cover member faces the front of the vehicle body. The air intake port is preferably provided (claim 6).

  According to this structure, since the vehicle width direction dimension of a cover member can be ensured comparatively large, the cross-sectional area of the distribution | circulation part inside can be expanded effectively. Therefore, the rigidity of the cover member can be effectively improved, and the amount of air blown from the air outlet on the downstream side through the circulation portion can be further increased. There is an advantage that dirt at the rear can be more effectively suppressed.

  In addition, since the air intake port at the front end of the cover member faces the front of the vehicle body, the air flowing along the side surface when the vehicle is running is efficiently taken into the air intake port and is downstream. Therefore, there is an advantage that dirt at the rear of the vehicle body can be more effectively suppressed.

  It is preferable that the cover member is arranged in a state in which an internal circulation portion thereof overlaps with the slide door rail in the vertical direction (Claim 7).

  According to this configuration, it is possible to sufficiently secure the cross-sectional area of the flow portion inside the cover member while suppressing the vertical width of the cover member to a relatively small size, so the strength of the cover member can be increased with a relatively compact configuration. There are advantages that it can be sufficiently secured and that the dirt at the rear of the vehicle body can be effectively suppressed.

  The tail lamp is preferably arranged in a state in which a horizontal line on the design thereof is substantially continuous with a lower side portion of the cover member.

  According to this configuration, it is possible to improve the appearance of the vehicle body by building a design with a sense of unity on the rear side surface of the vehicle body while realizing a compact component arrangement in which the cover member and the tail lamp are arranged close to each other. There is an advantage that you can.

  As described above, according to the sliding door rail cover structure for a vehicle of the present invention, it is possible to effectively suppress the dirt at the rear of the vehicle body without narrowing the interior space.

It is provided as a part.

  As described above, in the present embodiment, when the vehicle travels, the third outlet formed by the outer peripheral clearance of the tail lamp 11 or the like serves as an outlet for blowing out the air introduced into the circulation portion 47 from the air intake port 45. The air outlet 53 is provided, and the first and second air outlets 51 and 52 are provided in the rear part of the cover member 14 located in the vicinity of the tail lamp 11. When the vehicle travels, each of the air outlets 51 and 52 is provided. The blown-out air always flows around the tail lamp 11 by the air blown out through .about.53. Further, since each of the air outlets 51 to 53 as described above is simultaneously located at a side portion of the rear gate 10 or in the vicinity thereof, the air blown out from each of the air outlets 51 to 53 is at least a part thereof. Flows along the wall surface of the rear gate 10.

  As shown in FIGS. 8 and 9, among the first to third air outlets 51 to 53, the first air outlet 51 provided on the rear end surface of the cover member 14 has air blown therefrom. The rear window 17 is provided so as to flow toward the installation portion of the rear window 17. That is, since the rectifying plate 57 provided at the first air outlet 51 is directed obliquely upward, the air blown from the first air outlet 51 while being guided by the rectifying plate 57 is changed to the rear window. It is made to flow toward 17 installation parts.

Although not described in detail, a rectifying plate may be provided in the gap on the upper side of the tail lamp 11 so that the flow of air blown out from the portion is more reliably directed to the rear window 17.

  As described above, the rear side door 2 is formed of a rear-opening slide door that covers the entrance opening 3 on the side of the vehicle body so as to be openable and closable, and the quarter panel 7 as the vehicle body side wall on the rear side of the entrance opening 3. In a vehicle slide door rail cover structure including a slide door rail 12 that slidably supports the rear side door 2 and a cover member 14 that covers the slide door rail 12 from the outside of the vehicle. Is provided in the front portion of the cover member 14, and a flow portion 47 extending in the front-rear direction through which air taken in from the air intake port 45 can flow is provided in the cover member 14. The air introduced into the circulation part 47 is blown outside to a predetermined part of the rear part of the vehicle body located downstream of the circulation part 47. According to the configuration of the first embodiment in which the air outlets (first to third outlets 51 to 53) are provided, there is an advantage that dirt on the rear of the vehicle body can be effectively suppressed without narrowing the interior space. is there.

  That is, in the first embodiment, when the vehicle is running, air is taken in from the outside through the air intake 45 provided in the front part of the cover member 14 for shielding the slide door rail 12, and the taken-in air is Since it blows out from the blower outlets 51-53 provided in the predetermined | prescribed site | part of a vehicle body, the pressure fall in the negative pressure area | region A (refer FIG. 8) generated on the back side of a vehicle body is carried out by the said blowing flow. There is an advantage in that it is possible to effectively suppress the adhesion of dirt, such as rain and rainwater, which is wound up so as to be attracted to the negative pressure region A, to the rear part of the vehicle body.

  More specifically, when the vehicle travels, as shown in FIG. 8, a negative pressure region A is generated on the rear side of the vehicle body due to the influence of the airflow around the vehicle body. Ascending airflow B is generated from the vicinity of the ground surface along the rear end surface of the vehicle body by being sucked, but air is blown out from the air outlets 51 to 53 provided at the predetermined portion of the rear portion of the vehicle body as described above. If so, since the pressure drop in the negative pressure region A is suppressed, the strength of the updraft B attracted to the negative pressure region A is weakened. As a result, dirt such as dust or rainwater that scatters along with the rotation of the rear wheel R during rainy weather or the like is suppressed from being rolled up together with the rising airflow B, so that it is difficult for dirt to adhere to the rear part of the vehicle body. Will be kept relatively clean.

  In addition, in the above configuration, the circulation part 47 is formed using the internal space of the cover member 14 that covers the slide door rail 12 from the outside of the vehicle, and the air outlets 51 to 51 located downstream from the air intake 45 through the circulation part 47. Since the air is circulated to 53, it is possible to take in the air during traveling and blow it out to the rear side of the vehicle with a very rational configuration utilizing the space essential for the vehicle structure, and to narrow the interior space at all There is an advantage that dirt on the rear of the vehicle body can be effectively suppressed without rain.

  For example, the lower wall portion 21 of the quarter panel 7 located below the cover member 14 is provided with an intake port similar to the air intake port 45, and the air taken in from there is circulated to the rear side of the vehicle body. As the circulation part, it is conceivable to add a duct-like member to the inner side surface of the lower wall part 21, but in this case, the lower wall part 21 is caused by the presence of the duct-like circulation part. May protrude to the inside of the vehicle, and the occupant's living space or luggage space (that is, the interior space) surrounded by the quarter panel 7 including the lower wall portion 21 may be narrowed to some extent. On the other hand, when the air is circulated using the internal space of the cover member 14 necessary to shield the slide door rail 12 as in the first embodiment, the above-described problems are caused. Since the air flow path can be appropriately secured without being generated, there is an advantage that the dirt on the rear portion of the vehicle body can be effectively suppressed while sufficiently securing the interior space.

  Further, in the first embodiment, since the air intake 45 is provided in the front part of the cover member 14 spaced apart from the rear wheel R by a predetermined distance, It is possible to prevent dirt such as rainwater from being taken in from the air intake port 45 together with the traveling wind and introduced into the circulation part 47, and relatively clean air is blown out from the air outlets 51 to 53 on the rear side of the vehicle body. There is an advantage that dirt at the rear can be effectively suppressed.

  In the first embodiment, the cover member 14 is constituted by a hollow member having a closed cross-sectional space inside, and air is circulated through the flow part 47 including the closed cross-sectional space inside the cover member 14. However, as long as the flow part 47 uses the space between the outer wall (outer panel 42) of the cover member 14 and the mounting part (the recessed wall part 20) of the slide door rail 12, It does not necessarily have to be a closed section space. For example, the cover member 14 is constituted by a U-shaped cross-section member opened to the inside of the vehicle, and the circulation part is constituted by a space formed between the inner wall of the cover member 14 and the recessed wall part 20. You may make it do. However, when a circulation part is constituted by such an open space, there is a concern that air passing through the circulation part leaks to the outside in the middle.

  On the other hand, when the circulation part 47 is configured by a closed cross-sectional space formed inside the cover member 14 as in the first embodiment, it is taken into the circulation part 47 from the air intake port 45. Since the discharged air can be sent to the downstream side without leakage, the flow rate of the air blown out from the outlets 51 to 53 can be sufficiently secured, and dirt on the rear part of the vehicle body in the rainy weather etc. can be more effectively There is an advantage that it can be suppressed. In addition, by providing the circulation portion 47 having a closed cross-sectional space inside the cover member 14, the rigidity of the cover member 14 can be effectively improved and air mixed with some rainwater or the like can be collected. Even if it is taken into the circulation part 47 through the inlet 45, rainwater or the like in the air does not adhere to the slide door rail 12, so that the slide door rail 12 is effectively prevented from being rusted or soiled. Can do.

  Further, as in the first embodiment, it is formed at the rear portion of the cover member 14 as an air outlet for blowing out air introduced from the air intake port 45 into the inside of the cover member 14 (flow portion 47). When the 1st-3rd blower outlets 51-53 which consist of an opening, the outer periphery clearance gap, etc. of the tail lamp 11 are provided, the air blowing flow from each said blower outlets 51-53 is produced in the peripheral part of the said tail lamp 11. As a result, it is possible to effectively prevent dirt from adhering to the tail lamp 11 and the wall surface of the rear gate 10 around the tail lamp 11 during rainy weather, and as a result, the safety and usability of the vehicle can be effectively improved. There is an advantage that can be.

  That is, the air blown out from each of the outlets 51 to 53 prevents the tail lamp 11 from being contaminated in the rain or the like, so that the brake warning light, the direction indicator light, etc. built in the tail lamp 11 can be used. It is possible to prevent the display from becoming difficult to see for the driver or the like of the following vehicle, and it is possible to effectively improve the safety of the vehicle in rainy weather. Similarly, by suppressing the dirt of the rear gate 10 by the blowout flow from the outlets 51 to 53, it is possible to prevent the passenger's hand opening / closing the rear gate 10 from becoming dirty when loading / unloading the luggage into / from the rear cargo compartment. Therefore, it is possible to improve the usability of the rear gate 10 when it rains. Further, by generating a blow-out flow from the outlets 51 to 53 at the important parts of the rear part of the vehicle body such as the tail lamp 11 and the rear gate 10, the contamination of the important parts of the rear part of the vehicle body is suppressed with a relatively small amount of air blown out. Thus, there are advantages that the safety of the vehicle can be effectively improved and the aesthetic appearance of the rear part of the vehicle body can be maintained well.

  In the first embodiment, the front part of the second air outlet 52 or the third air outlet 53 is also provided around the portion of the tail lamp 11 located on the rear side surface of the vehicle body (the front part of the first lamp unit 61). However, since the front part of the first lamp unit 61 is not necessarily a part covered with the negative pressure region A, the air outlet is omitted around such a part. Is also possible. However, dirt may adhere to the tail lamp 11 due to factors other than the presence of the negative pressure region A. Therefore, as in the first embodiment, the tail lamp 11 including the front portion of the first lamp unit 61 is substantially omitted. Providing an air outlet around the entire area is advantageous in that the tail lamp 11 can be more reliably prevented from being contaminated.

  In the first embodiment, air blown out from a part of the first to third outlets 51 to 53 serving as air outlets is directed to the installation portion of the rear window 17 in the rear gate 10. Therefore, it is possible to effectively prevent dirt from adhering to the rear window 17 when it rains, and to ensure a good view (rear view) from the inside of the vehicle through the rear window 17. There are advantages.

  In the first embodiment, since the slide door rail 12 and the flow part 47 of the cover member 14 are arranged so as to overlap in the vertical direction, the vertical width of the cover member 14 is suppressed to a relatively small size. It is possible to secure a sufficient cross-sectional area of the circulation portion 47 inside. Accordingly, the rigidity of the cover member 14 can be effectively improved with a relatively compact configuration, and the amount of air blown out from the outlets 51 to 53 on the downstream side through the circulation portion 47 is sufficient. Can be ensured, and dirt at the rear of the vehicle body can be effectively suppressed.

  For example, as a mode different from the first embodiment, it is conceivable to provide a circulation part only at a position offset in the vertical direction from the installation part of the slide door rail 12, but in such a configuration, the cross-sectional area of the circulation part is If it is going to secure enough, it will be necessary to enlarge the up-and-down width of the above-mentioned cover member 14 greatly, and it becomes impossible to constitute cover member 14 compactly. On the other hand, according to the configuration of the first embodiment in which the circulation portion 47 and the slide door rail 12 are overlapped in the vertical direction, the cover member 14 is configured to be compact in the vertical direction, while the flow portion 47 is disconnected. It is possible to secure a sufficient area.

  In the first embodiment, since the attachment positions of the tail lamp 11 and the lower side of the cover member 14 are set so that the upper side of the tail lamp 11 and the lower side of the cover member 14 are substantially horizontal, the cover member 14 and the tail lamp 11 are arranged close to each other. There is an advantage that the appearance of the vehicle body can be further improved by constructing a design having a sense of unity on the rear side surface of the vehicle body, etc. while realizing the compact component arrangement.

  In the first embodiment, the upper side portion of the tail lamp 11 and the lower side portion of the cover member 14 are continuously arranged in a substantially horizontal direction. However, the portion of the tail lamp 11 that is continuous with the lower side portion of the cover member 14 has an appearance. Any specific horizontal line (a horizontal line on the design) that can be seen from the side is acceptable, and the specific type is not particularly limited. For example, as in the vehicle shown in FIG. 10, a tail lamp 111 having a vertically divided structure composed of a blinker lamp unit 112 having a built-in direction indicator lamp and a brake lamp unit 113 having a built-in brake warning light is provided. In this case, the attachment position of the tail lamp 111 may be set so that the dividing line L1 between the lamp units 112 and 113 is continuous with the lower side of the cover member 14. Even in this case, similarly to the first embodiment, the appearance of the rear portion of the vehicle body can be effectively improved while the cover member 14 and the tail lamp 111 are arranged in a compact manner.
