  In particular, the patch flange 20A of the patch 20 is joined to the fender flange 18A of the fender 18 by spot welding. Therefore, the patch 20 (including the patch flange 20A) can be firmly joined to the fender 18 (including the fender flange 18A), and the fender 18 (including the fender flange 18A) can be joined to the patch 20 (including the patch flange 20A). ) Can be further reinforced. In addition, unevenness can be prevented from occurring on the upper surface (design surface) of the upper portion of the fender 18, and the lower surface of the patch 20 can be smoothed (for example, burrs due to spot welding can be eliminated).

  Further, the patch flange 20 </ b> A is not provided on the inner side in the vehicle width direction of the hinge shaft 30 of the hood hinge 22. For this reason, when the collision body 34 collides with the upper part of the fender 18 on the upper side of the hinge shaft 30 from the upper side and the hinge base 24 and the hinge arm 28 are tilted inward in the vehicle width direction, the upper end of the hinge base 24 and Since the upper end of the hinge arm 28 is in contact with the fender flange 18A, the patch flange 20A can be prevented from inhibiting the hinge base 24 and the hinge arm 28 from tilting inward in the vehicle width direction. Accordingly, the fender flange 18A can easily tilt (bend and deform) with respect to the fender 18, and the hinge base 24 and the hinge arm 28 can be favorably tilted inward in the vehicle width direction.

  [Third Embodiment]

  7 shows a hinge structure 50 according to a third embodiment of the present invention in a cross-sectional view (a cross-sectional view taken along the line 1-1 in FIG. 3) as seen from the front of the vehicle.

  The hinge structure 50 according to the present embodiment has substantially the same configuration as that of the first embodiment, but differs in the following points.

  In the hinge structure 50 according to the present embodiment, the patch 20 in the first embodiment is not provided.

  The hood hinge 22 is integrally provided with a hinge flange 52 having an inverted L-shaped cross section as a tilting means (contact member) at the upper end of the hinge base 24. The hinge flange 52 has higher rigidity than the fender 18, and the lower portion of the hinge flange 52 extends upward from the upper end of the hinge base 24. The upper portion of the hinge flange 52 extends outward in the vehicle width direction from the upper end of the lower portion of the hinge flange 52, is inclined and curved along the upper portion of the fender 18, and the bent portion 52A ( The upper side surface of the upper portion and the lower portion is curved.

  Here, also in this embodiment, the same operations and effects as those in the first embodiment can be obtained.

  In particular, as in FIG. 2, when the collision body 34 collides with the upper part of the fender 18 on the upper side of the hinge shaft 30 from above and the upper part of the fender 18 interferes with the hood hinge 22, the upper part of the fender 18 is the hood. By abutting on the upper part of the hinge flange 52 on the upper side of the hinge 22 (the interference area where the upper part of the fender 18 interferes with the hood hinge 22 is increased), the upper part of the fender 18 becomes the upper end of the hinge base 24 and the hinge arm 28. It is suppressed that the upper end of the hinge base 24 and the upper end of the hinge arm 28 are encased by being locally deformed in an inverted U-shaped cross section by the upper end of the hinge. Accordingly, the hinge base 24 can be deformed inward in the vehicle width direction, and the hinge base 24 and the hinge arm 28 can be tilted inward in the vehicle width direction, and the fender 18 can be satisfactorily deformed downward. Thus, the collision load acting on the collision body 34 can be stabilized.

  Furthermore, the upper part of the hinge flange 52 is curved, and the upper surface of the upper part of the hinge flange 52 is smoothed (unevenness is eliminated). For this reason, when the upper part of the fender 18 contacts the upper part of the hinge flange 52, the upper part of the hinge flange 52 can slide well with respect to the upper part of the fender 18, and the hinge base 24 and the hinge arm 28 can be moved. It can be tilted inward in the vehicle width direction.

  Moreover, the upper side surface of the bent portion 52A of the hinge flange 52 is curved.

  For this reason, even when the upper part of the fender 18 abuts the curved part 52A of the hinge flange 52, the curved part 52A of the hinge flange 52 can be prevented from sticking into the upper part of the fender 18, and the curved part 52A of the hinge flange 52 can be prevented. It is possible to slide well with respect to the upper part of the fender 18, and the hinge base 24 and the hinge arm 28 can be easily tilted inward in the vehicle width direction.

  Further, when the hinge base 24 and the hinge arm 28 are tilted inward in the vehicle width direction and the bent portion 52A of the hinge flange 52 contacts the fender flange 18A, the bent portion 52A of the hinge flange 52 pierces the fender flange 18A. This can be suppressed, and the bent portion 52A of the hinge flange 52 can slide well with respect to the fender flange 18A. Thereby, the fender flange 18A can be easily tilted (bent and deformed) with respect to the fender 18, and the fender flange 18A can be prevented from inhibiting the hinge base 24 and the hinge arm 28 from tilting inward in the vehicle width direction. 24 and the hinge arm 28 can be favorably tilted inward in the vehicle width direction.

  Further, the patch 20 in the first embodiment is not joined to the upper portion of the fender 18. For this reason, it is possible to prevent unevenness on the upper surface (design surface) of the upper part of the fender 18 and to smooth the lower surface of the upper part of the fender 18 (for example, it is possible to eliminate burrs due to spot welding).

  [Fourth Embodiment]

  8 shows a hinge structure 60 according to a fourth embodiment of the present invention in a cross-sectional view (a cross-sectional view taken along line 1-1 in FIG. 3) as viewed from the front of the vehicle.

  The hinge structure 60 according to the present embodiment has substantially the same configuration as the third embodiment, but differs in the following points.

  In the hinge structure 60 according to the present embodiment, in the hood hinge 22, the upper portion of the hinge flange 52 on the upper side of the hinge base 24 extends inward in the vehicle width direction from the upper end of the lower portion of the hinge flange 52, It is inclined and curved along the upper part of the fender 18, and the upper side surface of the curved portion 52A (boundary portion between the upper portion and the lower portion) of the hinge flange 52 is curved.

  The vicinity of the tip 52B of the hinge flange 52 is curved to be a curved portion 52C, and the tip 52D of the hinge flange 52 is directed downward toward the inside in the vehicle width direction in the vicinity of the fender flange 18A of the fender 18. The upper side surface of the bent portion 52C of the hinge flange 52 is curved while being inclined in the direction. The front end portion 52D of the hinge flange 52 has a flat plate shape or a curved plate shape protruding upward, and the vertical width of the front end portion 52D of the hinge flange 52 is made smaller than the vertical width of the fender flange 18A. ing.

  The hinge flange 52 is arranged so as not to obstruct the opening and closing of the hood 32 due to the rotation of the hinge arm 28 with respect to the hinge base 24.

  Here, also in this embodiment, the same operations and effects as those of the third embodiment can be achieved.

  In particular, as in FIG. 2, when the collision body 34 collides with the upper part of the fender 18 on the upper side of the hinge shaft 30 from above and the upper part of the fender 18 interferes with the hood hinge 22, the upper part of the fender 18 is the hood. By abutting on the upper part of the hinge flange 52 on the upper side of the hinge 22 (the interference area where the upper part of the fender 18 interferes with the hood hinge 22 is increased), the upper part of the fender 18 becomes the upper end of the hinge base 24 and the hinge arm 28. It is suppressed that the upper end of the hinge base 24 and the upper end of the hinge arm 28 are encased by being locally deformed in an inverted U-shaped cross section by the upper end of the hinge. Accordingly, the hinge base 24 can be deformed inward in the vehicle width direction, and the hinge base 24 and the hinge arm 28 can be tilted inward in the vehicle width direction, and the fender 18 can be satisfactorily deformed downward. Thus, the collision load acting on the collision body 34 can be stabilized.

  Moreover, the upper side surface of the curved portion 52C of the hinge flange 52 is curved. For this reason, even when the upper part of the fender 18 contacts the curved part 52C of the hinge flange 52, the curved part 52C of the hinge flange 52 can be prevented from sticking into the upper part of the fender 18, and the curved part 52C of the hinge flange 52 It is possible to slide well with respect to the upper part of the fender 18, and the hinge base 24 and the hinge arm 28 can be easily tilted inward in the vehicle width direction.

  Furthermore, the tip 52D of the hinge flange 52 is inclined in a direction toward the lower side as it goes inward in the vehicle width direction. For this reason, when the hinge base 24 and the hinge arm 28 are tilted inward in the vehicle width direction and the tip 52B of the hinge flange 52 comes into contact with the fender flange 18A, the tip 52B of the hinge flange 52 pierces the fender flange 18A. And the tip 52B of the hinge flange 52 can be satisfactorily slid with respect to the fender flange 18A. Thereby, the fender flange 18A can be easily tilted (bent and deformed) with respect to the fender 18, and the fender flange 18A can be prevented from inhibiting the hinge base 24 and the hinge arm 28 from tilting inward in the vehicle width direction. 24 and the hinge arm 28 can be favorably tilted inward in the vehicle width direction.

  In the present embodiment, the vertical width of the tip 52D of the hinge flange 52 is made smaller than the vertical width of the fender flange 18A. However, like the hinge structure 70 according to the modification shown in FIG. The vertical width of the tip 52D of the hinge flange 52 may be larger than the vertical width of the fender flange 18A.

  In this case, when the hinge base 24 and the hinge arm 28 are tilted inward in the vehicle width direction, the upper side surface of the distal end portion 52D of the hinge flange 52 contacts the fender flange 18A. For this reason, while being able to suppress that the front-end | tip 52B of the hinge flange 52 pierces the fender flange 18A, the front-end | tip part 52D of the hinge flange 52 can slide favorably with respect to the fender flange 18A. Thereby, the fender flange 18A can be easily tilted (bent and deformed) with respect to the fender 18, and the fender flange 18A can be prevented from inhibiting the tilting of the hinge base 24 and the hinge arm 28 toward the inside in the vehicle width direction.

  Moreover, in the said 3rd Embodiment and 4th Embodiment (including a modification), it was set as the structure which provided the hinge flange 52 in the hinge base 24, However, The structure which provided the hinge flange 52 in the hinge arm 28 It is good.

  Furthermore, in the said 3rd Embodiment and 4th Embodiment (including a modification), it was set as the structure which integrally formed the hinge flange 52 in the hood hinge 22, However, Metal or resin hinge flange 52 is used. May be manufactured separately from the hood hinge 22 and attached to the hood hinge 22.

  [Fifth Embodiment]

  FIG. 10 shows a sectional view of the hinge structure 80 according to the fifth embodiment of the present invention as viewed from the front of the vehicle (a sectional view taken along the line 1-1 in FIG. 3). The hinge structure 80 is shown in a perspective view as seen from the diagonally left front of the vehicle.

  The hinge structure 80 according to the present embodiment has substantially the same configuration as the first embodiment, but differs in the following points.

  In the hinge structure 80 according to the present embodiment, the patch 20 in the first embodiment is not provided.

  The hood hinge 22 has a lower end of a cap 82 (cover) made of hard resin (which may be made of metal) as a tilting means (abutting member) and having an inverted J-shaped cross section on the outside of the hinge base 24 in the vehicle width direction. The cap 82 is attached (tightened) by the clip 84 as an attaching means, and the outer side portion of the cap 82 in the vehicle width direction covers the outer side of the hinge shaft 30 in the vehicle width direction.

  The upper part of the cap 82 has an inverted U-shaped plate shape in cross section, and the upper part of the cap 82 covers the upper end of the hinge base 24 and the upper end of the hinge arm 28 from the upper side and both outer sides in the vehicle width direction. The upper surface of the cap 82 is flat (may be curved so as to protrude upward), and both ends of the upper surface of the cap 82 in the vehicle width direction are curved.

  The cap 82 is arranged so as not to obstruct the opening and closing of the hood 32 due to the rotation of the hinge arm 28 with respect to the hinge base 24.

  Here, also in this embodiment, the same operations and effects as those in the first embodiment can be obtained.

  In particular, as in FIG. 2, when the collision body 34 collides with the upper part of the fender 18 on the upper side of the hinge shaft 30 from above and the upper part of the fender 18 interferes with the hood hinge 22, the upper part of the fender 18 is the hood. By abutting on the upper part of the cap 82 on the upper side of the hinge 22 (the interference area where the upper part of the fender 18 interferes with the hood hinge 22 is increased), the upper part of the fender 18 is the upper end of the hinge base 24 and the upper end of the hinge arm 28. Therefore, the upper end of the hinge base 24 and the upper end of the hinge arm 28 are prevented from being locally deformed into an inverted U-shaped cross section. Accordingly, the hinge base 24 can be deformed inward in the vehicle width direction, and the hinge base 24 and the hinge arm 28 can be tilted inward in the vehicle width direction, and the fender 18 can be satisfactorily deformed downward. Thus, the collision load acting on the collision body 34 can be stabilized.

  Further, the upper surface of the cap 82 is flattened, and the upper surface of the cap 82 is smoothed (unevenness is eliminated). For this reason, when the upper part of the fender 18 comes into contact with the upper surface of the cap 82, the upper surface of the cap 82 can slide satisfactorily with respect to the upper part of the fender 18, and the hinge base 24 and the hinge arm 28 can be satisfactorily secured to the vehicle width. It can be tilted inward.

  Moreover, both ends of the upper surface of the cap 82 in the vehicle width direction are curved.

  For this reason, even when the upper portion of the fender 18 abuts against the end portion in the vehicle width direction of the upper surface of the cap 82, the end portion in the vehicle width direction of the upper surface of the cap 82 can be prevented from being stuck into the upper portion of the fender 18. The end in the vehicle width direction of the upper surface can slide well with respect to the upper portion of the fender 18, and the hinge base 24 and the hinge arm 28 can be easily tilted inward in the vehicle width direction.

  Further, when the hinge base 24 and the hinge arm 28 are tilted inward in the vehicle width direction and the vehicle width direction inner side end portion of the upper surface of the cap 82 contacts the fender flange 18A, the vehicle width direction end of the upper surface of the cap 82 is reached. It is possible to suppress the portion from sticking into the fender flange 18A, and the inner end in the vehicle width direction of the upper surface of the cap 82 can slide well with respect to the fender flange 18A. Thereby, the fender flange 18A can be easily tilted (bent and deformed) with respect to the fender 18, and the fender flange 18A can be prevented from inhibiting the hinge base 24 and the hinge arm 28 from tilting inward in the vehicle width direction. 24 and the hinge arm 28 can be preferably tilted inward in the vehicle width direction.

  Further, the patch 20 in the first embodiment is not joined to the upper portion of the fender 18. For this reason, it is possible to prevent unevenness on the upper surface (design surface) of the upper part of the fender 18 and to smooth the lower surface of the upper part of the fender 18 (for example, it is possible to eliminate burrs due to spot welding).

  In the present embodiment, the cap 82 is provided on the hinge base 24, but the cap 82 may be provided on the hinge arm 28.

  Further, in the present embodiment, the cap 82 is manufactured separately from the hood hinge 22 and attached to the hood hinge 22. However, the cap 82 may be formed integrally with the hood hinge 22.
