Description

  The present invention is a bumper face that is installed at the front end of a vehicle body and has an opening for introducing a running wind into the engine room at the bottom, and is installed at the rear of the bumper face to provide a heat exchanger for cooling the engine. The present invention relates to a front structure of an automobile including a shroud upper that is attached to an upper portion.

Conventionally, a structure in which an intake intake for introducing air into an engine combustion chamber is provided on the shroud upper is known. However, in such a structure, there is a risk that water such as water or snow that has flowed up from the opening under the bumper face and wound upward may enter the intake intake, so a member for preventing this is provided. May be. For example, in Patent Document 1 below, a seal board that protrudes in front of the vehicle body is provided on the front portion of the shroud upper, and a shield that protrudes rearward on the back side of a bumper face (front bumper) positioned in front of the heat exchanger. A part is provided. According to such a structure, a double sealing effect can be obtained by the seal board provided on the shroud upper and the shielding part provided on the bumper face.
Japanese Utility Model Publication No. 7-4133

  However, the structure described in Patent Document 1 in which a protrusion for sealing such as the shielding portion is provided on the bumper face has a problem that it is difficult to finish the appearance of the bumper face well. In other words, the bumper face is generally made of a resin molded product. However, if the above-described protrusion is provided on the back side of such a bumper face, molding defects such as sink marks at the time of resin molding will occur at the protrusion installation portion. The resulting surface dents or the like are likely to occur, which may impair the appearance of the vehicle body.

  The present invention has been made in view of the above circumstances, and provides a front structure of an automobile that can reliably prevent moisture from entering the intake intake while maintaining a good appearance of the vehicle body. The purpose is to do.

  In order to solve the above-mentioned problems, the present invention is installed at the front end of the vehicle body, and has a bumper face formed at the lower portion with an opening for introducing running wind into the engine room, and installed behind the bumper face. In the front structure of the automobile provided with a shroud upper that is attached to the upper part of the heat exchanger for cooling the engine, an intake intake for taking air into the engine is installed on the shroud upper. A front surface portion of the shroud upper includes a first seal plate that protrudes forward so as to fill a gap with the bumper face, and a second seal plate that is positioned a predetermined distance above the first seal plate. Is installed along the vehicle width direction (Claim 1).

  According to the present invention, the first seal plate that protrudes forward so as to fill the gap between the shroud upper and the front bumper face in the front portion of the shroud upper that has the intake intake for the engine installed on the upper side. And a second seal plate that is a predetermined distance above the second seal plate, so that water such as water or snow that has flowed in through the opening formed in the lower part of the bumper face and rolled up is Intrusion into the intake port through the shroud upper and the bumper face can be prevented twice. In addition, since both the first and second sealing plates are provided on the shroud upper side, unlike the structure described in Patent Document 1 in which a sealing protrusion is provided on the back side of the bumper face, the surface of the bumper face is sinked. Thus, there is an advantage that the appearance of the vehicle body can be favorably maintained by effectively preventing the occurrence of molding defects such as the above.

  Preferably, the first and second seal plates are constituted by an integrally molded product made of a separate member from the shroud upper.

  As described above, when the first and second seal plates are constituted by a member different from the shroud upper, it is possible to replace only the seal plate independently at the time of a vehicle front collision accident or the like. There is an advantage that the sealing property can be secured without deteriorating the repairability of the vehicle. In addition, since the first and second seal plates are integrally molded products, it is possible to avoid an increase in the number of parts more than necessary and to easily ensure the rigidity of the seal plates.

  When the intake port is installed on the shroud door upper side in the vehicle width direction, the first and second seal plates are located on the inner side in the vehicle width direction than the installation portion of the intake port. It is preferable that a vertical wall portion extending in the vertical direction so as to partition the space is formed.

  As described above, when the vertical wall portion is provided between the first and second seal plates, the water accumulated near the center of the upper surface portion of the first seal plate moves to the outside in the vehicle width direction and the intake air. Since the approach to the intake port can be prevented by the presence of the vertical wall portion, there is an advantage that it is possible to more reliably avoid the situation where the moisture enters the intake port. Further, by providing the vertical wall portion, the rigidity of the first and second seal plates can be effectively improved.

  In this case, it is preferable that an extension portion extending further upward than the second seal plate from the upper end portion of the vertical wall portion is further formed.

  In this way, it is possible to prevent moisture accumulated near the center of the upper surface of the second seal plate from moving to the intake intake side, and more reliably infiltrate moisture into the intake intake. Can be prevented.

  Moreover, it is preferable that the space between the first and second seal plates is opened at both left and right ends.

  In this way, water accumulated on the side of the upper surface of the first seal plate (that is, the side between the first and second seal plates) can be discharged from both the left and right ends. It is possible to suppress the water itself from being accumulated on the upper surface portion of the first seal plate. As a result, there is an advantage that it is possible to more effectively avoid the water from being blown up and entering the intake port.

  In this case, it is preferable that the left and right side portions of the first and second seal plates are constituted by inclined surface portions whose installation height decreases toward the outside (Claim 6).

  In this way, the water accumulated on the upper surface portions of the first and second seal plates can be positively discharged from both the left and right end portions, and moisture can be discharged on the upper surface portions of the first and second seal plates. Can be more effectively suppressed.

  The above configuration further includes a shroud drawer to which a lower portion of the heat exchanger is attached, and a pair of left and right shroud sides connecting the shroud drawer and the shroud upper, and is downward from both left and right ends of the first seal plate. It is preferable that a side seal portion extending in the direction is installed so as to fill a gap between the shroud side and the bumper face.

  As described above, when the side seal portion extending downward from the left and right end portions of the first seal plate and filling the gap between the shroud side and the bumper face is provided, the left and right sides of the first and second seal plates are provided. It is possible to prevent the moisture discharged from both ends from being blown back inward in the vehicle width direction, and thus the discharged moisture can be reliably led out in a direction away from the intake intake. There is an advantage that moisture can be more reliably prevented from entering the inlet.

  When a front grill is installed in front of the first and second seal plates, a projecting portion projecting rearward from the back side of the front grill is provided between the first and second seal plates in the vehicle width direction. It is preferable that it is installed so that it may extend in (claim 8).

  Thus, when the protrusion part which protrudes back from the back side of the front grille is provided between the first and second seal plates, the maze is formed by the protrusion part and the first and second seal plates. Therefore, there is an advantage that it is possible to more reliably avoid moisture from passing through the first and second seal plates and reaching the intake port.

  As described above, according to the front structure of an automobile of the present invention, it is possible to reliably prevent moisture from entering the intake air intake while maintaining a good appearance of the vehicle body.

It is a substantially rectangular frame-like member having sides 20c, 20c, and is fixed to the front portion of the vehicle body 1 by being connected to a vehicle body side member (not shown).

  As shown in FIGS. 2 and 4, a pair of left and right crash cans 18, 18 are interposed between the front side frames 16, 16 and the bumper reinforcement 15. The crash can 18 is formed in a rectangular tube shape, and is configured to absorb the impact energy applied from the front via the bumper reinforcement 15 by being compressed and deformed in the event of a frontal collision of the vehicle. ing.

  A flange member 18a is welded to the rear end portion of the crash can 18, and the flange member 18a is fastened to the flange member 16a welded to the front end portion of the front side frame 16 with a bolt or the like. The front side frame 16 and the crash can 18 are coupled via the flange members 16a and 18a.

  On the other hand, a bracket 34 is welded to the front end portion of the crash can 18, and a first portion 34a formed along the back surface of the bumper reinforcement 15 in the bracket 34 is bumper rain by bolt fastening or the like. It is fixed to the force 15. Further, the bracket 34 has a second portion 34b having a substantially U-shaped cross-sectional view formed continuously with the first portion 34a, and the second portion 34b is a shroud side 20c of the shroud panel 20. It is being fixed to the front part of this by bolt fastening etc. That is, the bumper reinforcement 15 is fixed to both the crash can 18 and the shroud panel 20 via the bracket 34.

  Further, as shown in FIG. 2, the upper end portion of the bumper reinforcement 15 and the front surface portion of the shroud upper 20a are connected via a support member 38, and the shroud side 20c and the flange member 18a of the crash can 18 are However, the support rigidity of the bumper reinforcement 15 and the shroud panel 20 is secured more firmly by being connected via the connecting portion 36 protruding from the side surface portion of the shroud side 20c.

  As shown in FIGS. 2 and 3, on the shroud upper 20 a of the shroud panel 20, an intake intake 30 to which the front end portion of the intake duct 32 for the engine is connected is installed. Air is taken into the combustion chamber of the engine. As shown in FIG. 2, the intake port 30 is installed on the shroud upper 20a on the outer side in the vehicle width direction.

  Further, water, snow, or the like that flows up into the front portion of the shroud upper 20a from the opening 10a of the bumper face 10 (more specifically, a gap in the lattice of the lower grill 11 therein) and winds upward. A shielding member 22 for preventing moisture (see arrow A in FIG. 3) from entering the intake intake 30 through the back surface of the bumper face 10 and the shroud upper 20a is provided in the vehicle width direction. It is installed to extend along. The shielding member 22 includes a first seal plate 24 projecting forward so as to fill a gap between the front surface portion of the shroud upper 20a and the bumper face 10, and a predetermined distance above the first seal plate 24. It is an integrally molded product having a second seal plate 25 provided, and is fixed to the front surface portion of the shroud doorper 20a by a locking fastener (not shown).

  As shown in FIGS. 2 and 5, the shielding member 22 is provided on the inner side in the vehicle width direction from the installation portion of the intake port 30 in the shroud upper 20 a from the upper surface portion of the first seal plate 24. A vertical seal plate 28 is integrally formed so as to extend upward and to extend to a predetermined height across the second seal plate 25 on the upper side. That is, the vertical seal plate 28 includes a vertical wall portion 28a extending in the vertical direction so as to partition the space between the first and second seal plates 24, 25, and upward from an upper end portion of the vertical wall portion 28a. It is comprised from the extended part 28b extended.

  The left and right side portions of the first and second seal plates 24 and 25 are configured by inclined surface portions 24a and 25a whose installation height decreases toward the outside. Of these, the side seal portion 26 extending downward along the inner side of the shroud side 20c from the outer end portion of the lower inclined surface portion 24a forms a gap between the shroud side 20c and the back surface of the bumper face 10. It is installed to fill. The side seal portion 26 is fastened and fixed to the bracket 34 fixed to the front surface of the shroud side 20c, more specifically, to the inner side surface of the second portion 34b (FIG. 4) having a U-shaped cross section of the bracket 34. Has been. On the other hand, since a vertical wall-like member such as the side seal portion 26 is not provided between the outer end portions of the inclined surface portions 24a and 25a, the first and the first including the inclined surface portions 24a and 25a are provided. The space between the second seal plates 24 and 25 is open at both left and right ends.

  On the upper surface of the second seal plate 25, a pair of left and right protection members 40, 40 that protrude upward while being curved toward the rear side of the vehicle are installed. The protective member 40 plays a role of preventing the hood hood 5 (FIG. 1) from being opened from the outside for the purpose of theft or the like. That is, a latch mechanism for maintaining the hood hood 5 in the closed state is provided near the center of the front end portion of the hood hood 5, and an opener for linking the operation portion installed near the driver's seat with the latch mechanism. Since a cable (not shown) is routed so as to pass behind the front grille 14, when there is no shield between the opener cable and the front grille 14, a tool is removed from the front grille 14. For example, an action of releasing the lock state of the hood hood 5 may be performed, for example, by inserting a hook etc. into the opener cable. On the other hand, when the protective member 40 as described above is installed on the upper surface portion of the second seal plate 25, the gap between the opener cable and the front grille 14 can be shielded by the protective member 40. Therefore, the unlocking operation as described above can be effectively prevented.

  As shown in FIG. 3, on the back side of the front grill 14, a projecting portion 14a projecting rearward at the height position between the first and second seal plates 24, 25 is provided along the vehicle width direction. It is installed to extend. In addition, the front grille 14 has a grid in the right end region (the region painted thinly in FIG. 1) closed so that moisture such as water or snow enters the intake intake 30 through the region. This has been prevented.

  As described above, according to the above-described embodiment, the gap between the shroud doorper 20a and the bumper face 10 in front of the shroud doorper 20a is filled in the front portion of the shroud upper 20a provided with the intake intake 30 for the engine on the upper side. Since the double shielding member 22 having the first seal plate 24 protruding forward and the second seal plate 25 above the predetermined distance is installed, the opening formed in the lower portion of the bumper face 10 Moisture such as water and snow (see arrow A in FIG. 3) flowing in from 10a and the like and rolling upward penetrates between the shroud upper 20a and the bumper face 10 and enters the intake intake 30. Double prevention is possible. In addition, since the shielding member 22 having the first and second seal plates 24 and 25 is provided on the shroud upper 20a side, a sealing protrusion is provided on the back side of the bumper face 10 as described in Patent Document 1. Unlike the above, there is an advantage that the appearance of the vehicle body 1 can be favorably maintained by effectively preventing molding defects such as sink marks on the surface of the bumper face 10.

  In particular, when the shielding member 22 having the first and second seal plates 24 and 25 is formed of a member different from the shroud doorper 20a as in the above-described embodiment, in the event of a frontal collision of the vehicle, etc. Since only the shielding member 22 can be replaced alone, there is an advantage that the repair cost of the vehicle can be effectively reduced. That is, if the shielding member 22 and the shroud upper 20a are integrally formed, the shielding member 24, 25 of the shielding member 22 is deformed in the event of a frontal collision of the vehicle. However, if the shielding member 22 and the shroud doorper 20a are configured separately as in the above-described configuration, the front collision accident as described above may occur. Sometimes only the shielding member 22 needs to be replaced, so that the vehicle can be repaired easily and at low cost. Further, since the shielding member 22 is constituted by a single part integrally having the first and second seal plates 24, 25, it is possible to avoid an increase in the number of parts more than necessary, and the seal plates 24, The rigidity of 25 can be easily ensured.

  Further, as in the above-described embodiment, the intake intake 30 is installed on the shroud doorper 20a on the outer side in the vehicle width direction, and the first intake is located further inward in the vehicle width direction than the installation portion of the intake intake 30. When the vertical wall portion 28a extending in the vertical direction is provided so as to partition the space between the second seal plates 24 and 25, the moisture accumulated near the center of the upper surface portion of the first seal plate 24 is lateral. There is an advantage that it is possible to effectively avoid moving into the intake intake 30 and moving to the intake intake 30. That is, a part of the water such as water or snow that flows into the engine room from the opening 10a of the bumper face 10 and winds upward passes through the first seal plate 24, and so on. There is a possibility that moisture may accumulate on the upper surface portion of the first seal plate 24. In such a case, the vicinity of the center of the upper surface portion of the first seal plate 24 may have moisture compared to the left and right outer portions. If the vertical wall portion 28 a as described above is provided between the first and second seal plates 24, 25, the moisture will be along the upper surface of the first seal plate 24. Since it can be prevented from moving in a direction approaching the installation portion of the intake intake 30 (right side in FIG. 2), the above-mentioned moisture is effectively blown upward and enters the intake intake 30 effectively. It can be. Further, by providing the vertical wall portion 28a, the rigidity of the first and second seal plates 24, 25 can be effectively improved.

  Further, in the above embodiment, since the extending portion 28b extending from the upper end portion of the vertical wall portion 28a to the upper side of the second seal plate 25 is provided, it has accumulated near the center of the upper surface portion of the second seal plate 25. It is also possible to prevent moisture from moving to the intake intake 30 side, and to more reliably prevent moisture from entering the intake intake 30.

  Further, when the space between the first and second seal plates 24 and 25 is opened at both the left and right end portions as in the above embodiment, the upper surface side of the first seal plate 24 ( That is, since the water accumulated in the side portion between the first and second seal plates 24 and 25 can be discharged from both left and right end portions, the water accumulates on the upper surface portion of the first seal plate 24. This can be suppressed, and as a result, there is an advantage that it is possible to more effectively avoid the moisture from being blown up and entering the intake port 30.

  Further, in the above embodiment, since the left and right side portions of the first and second seal plates 24, 25 are configured by the inclined surface portions 24a, 25a whose installation height decreases toward the outside, the first and second portions are arranged. The moisture accumulated on the upper surface portions of the seal plates 24 and 25 can be positively discharged from both the left and right end portions, and the moisture is accumulated on the upper surface portions of the first and second seal plates 24 and 25. It can be effectively suppressed.

  Further, as in the above embodiment, the side seal portion 26 that extends downward from the left and right end portions of the first seal plate 24 (the outer end portion of the inclined surface portion 24a) and fills the gap between the shroud side 20c and the bumper face 10 is provided. In the case where it is provided, it is possible to prevent the moisture discharged from the left and right ends of the first and second seal plates 24, 25 from being blown back to the inside in the vehicle width direction. Since it can be reliably led out in the direction away from the intake port 30, there is an advantage that moisture can be more reliably prevented from entering the intake port 30. Further, depending on the running state of the vehicle, the hot air of the engine installed behind the heat exchanger 12 may flow forward along the left and right sides of the engine room. 26 is provided, it is possible to prevent the hot air of the engine from being blown back through the front of the shroud side 20c, so that the heat exchanger 12 is caused by the hot air of the engine hitting the heat exchanger 12. There is also an advantage that it is possible to effectively avoid a decrease in performance.

  Moreover, when the protrusion part 14a which protrudes back from the back side of the front grille 14 is provided between the 1st and 2nd seal plates 24 and 25 like the above-mentioned embodiment, broken line arrow B of FIG. As shown in FIG. 2, a labyrinth-like seal structure can be constructed by the projecting portion 14a and the first and second seal plates 24, 25. Therefore, the first and second seal plates 24, 25 are There is an advantage that it is possible to more reliably avoid the passage of moisture to the intake intake 30 through the passage.
