Abstract

PROBLEM TO BE SOLVED: To provide desired joining strength on a pair of lower side flanges.SOLUTION: The lower side flange 22 is positioned in a position dislocated to the vehicle upper side to a lower side flange 32 in a state of forming a projection part 34 forming a projection on the lower side flange 22 side in the lower side flange 32, and an adhesive 36 is applied to a vehicle lower side part 32A more than the projection part 34 in the lower side flange 32 in this state. Thus, even when a cowl top side inner 12 is moved to the vehicle lower side so that the lower side flanges 22 and 32 are opposed, since the projection part 34 guards the adhesive 36, the lower side flange 22 can be restrained from chipping off the adhesive 36. Moreover, since the projection part 34 is crushed by spot-welding after opposing the lower side flanges 22 and 32, the adhesive 36 can be thereby brought into close contact with the lower side flanges 22 and 32. Thus, the desired joining strength can be provided on the lower side flanges 22 and 32.

The lower wall portion 26 extends inward in the vehicle width direction from the vehicle lower side end portion of the outer wall portion 28, is disposed on the vehicle lower side of the upper wall portion 16, and faces the upper wall portion 16. ing. The outer wall portion 28 extends in the vehicle vertical direction, is disposed on the outer side in the vehicle width direction of the inner wall portion 18 described above, and faces the inner wall portion 18.

  An outer flange 30 extending toward the vehicle width direction outer side is formed at the vehicle upper end of the outer wall portion 28, and the vehicle width direction inner end of the lower wall portion 26 toward the vehicle lower side. An extending lower flange 32 is formed as an example of a joined portion.

  The lower flange 32 is formed with a protrusion 34 that protrudes toward the lower flange 22. A plurality of the protrusions 34 may be formed in the shape of a protrusion and arranged in the front-rear direction of the vehicle at intervals, or may be a protrusion that continues in the front-rear direction of the vehicle.

  The vehicle body member 10 shown in FIG. 1 is shown in a state before the protrusion 34 is crushed after the cowl top side inner 12 is assembled to the cowl top side outer 14. The vehicle body member 10 is assembled in the following manner, and its final form is as follows.

  That is, first, as indicated by an imaginary line (two-dot chain line) in FIG. 1, the lower flange 22 is shifted to the vehicle upper side (one side in the extending direction of the joined portion) with respect to the lower flange 32. The cowl top side inner 12 is positioned at a position before assembly with respect to the cowl top side outer 14 so as to be positioned. In this state, the adhesive 36 is applied to a portion 32A of the lower flange 32 on the vehicle lower side (the other side in the extending direction of the joined portion) than the protrusion 34 (adhesive application step).

  Subsequently, as shown by a solid line in FIG. 1, the cowl top side inner 12 is moved to the vehicle lower side so that the lower flange 22 and the lower flange 32 face each other, and the cowl top side inner 12 is cowled. It is located at the assembly position with respect to the top side outer 14 (moving step).

  Next, as shown in the upper view of FIG. 2, a pair of spot welding welding guns 38 are set to a height at which the protrusions 34 are located. Then, a pair of welding guns 38 is pressed against the lower flange 22 and the lower flange 32 from both sides to perform spot welding. As a result, as shown in the lower diagram of FIG. 2, the protrusion 34 is crushed by pressing the lower flange 22 and the lower flange 32 together, and the crushed portion formed by crushed this protrusion 34. 40 and the lower flange 22 are joined by a welded portion 42 by spot welding.

  In addition, as described above, when the lower flange 22 and the lower flange 32 are pressed against each other during spot welding, a part of the adhesive 36 is crushed and flows to the upper side of the vehicle from the portion 40, and is crushed in the lower flange 32. The part 32A on the vehicle lower side and the part 32B on the vehicle upper side than the portion 40 are joined by the lower flange 22 and the adhesive 36 (joining process). The outer flanges 20 and 30 shown in FIG. 1 are joined by an adhesive or welding.

  The vehicle body member 10 is assembled in the manner described above. Further, in the vehicle body member 10 assembled in the above manner, the lower flange 32 is finally crushed 40 formed by crushing the protrusion 34 as shown in the lower drawing of FIG. It is set as the form which has.

  Next, the operation and effect of the first embodiment of the present invention will be described.

  First, a comparative example will be described in order to clarify the operation and effect of the first embodiment of the present invention. In the comparative example shown in FIG. 6, the same reference numerals are used for the structures having the same names as those of the first embodiment of the present invention described above for the sake of easy comparison.

  The vehicle body member 100 according to the comparative example shown in FIG. 6 is configured such that the protrusion 34 is omitted from the vehicle body member 10 according to the first embodiment of the present invention described above.

  In the method of assembling the vehicle body member 100 according to this comparative example, first, as shown in the upper diagram of FIG. 6, the lower flange 22 is positioned at a position shifted to the vehicle upper side with respect to the lower flange 32. In this state, the adhesive 36 is applied to the lower flange 32. Subsequently, as shown in the lower diagram of FIG. 6, the cowl top side inner 12 is moved to the vehicle lower side so that the lower flange 22 faces the lower flange 32.

  However, in the vehicle body member 100 according to this comparative example, when the cowl top side inner 12 is moved to the vehicle lower side with the adhesive 36 applied to the lower flange 32, the lower flange 22 is attached to the adhesive 36. May be scraped off. In this case, there is a possibility that the desired bonding strength cannot be obtained for the lower flange 22 and the lower flange 32.

  On the other hand, in the method for assembling the vehicle body member 10 according to the first embodiment of the present invention, as shown by the imaginary line (two-dot chain line) in FIG. In a state where the lower flange 32 is formed, the lower flange 22 is positioned at a position shifted to the upper side of the vehicle with respect to the lower flange 32. In this state, the lower flange 32 is located on the vehicle lower side than the protrusion 34. The adhesive 36 is applied to the site 32A.

  Therefore, as shown by the solid line in FIG. 1, the cowl top side inner 12 is moved to the vehicle lower side so that the lower flange 22 and the lower flange 32 face each other, and the cowl top side inner 12 is moved to the cowl top side. Even when the protrusion 34 guards the adhesive 36 even when positioned at the assembly position with respect to the outer 14, it is possible to suppress the lower flange 22 from scraping off the adhesive 36.

  In particular, due to the influence of manufacturing errors, for example, even when the lower flange 22 is located closer to the lower flange 32, the lower flange 22 slides on the protruding portion 34 and moves away from the lower flange 32. Since it is shifted, it can suppress more effectively that the lower flange 22 scrapes off the adhesive agent 36.

  In addition, as shown in FIG. 2, the protrusion 34 is crushed by spot welding after the lower flange 22 and the lower flange 32 are opposed to each other, whereby the adhesive 36 is removed from the lower flange. 22 and the lower flange 32. As described above, desired bonding strength can be obtained for the lower flange 22 and the lower flange 32.

The portion 32 </ b> B was joined to the lower flange 22 by the adhesive 36. However, at the time of spot welding, a part of the adhesive 36 is crushed and does not flow to the upper side of the vehicle from the portion 40, and only the portion 32 </ b> A below the crushed portion 40 in the lower flange 32 is the lower flange 22. It may be joined by an adhesive 36.

  Moreover, although the protrusion 34 was crushed by performing spot welding to the lower flange 22 and the lower flange 32, for example, a pressing member or the like is applied to the lower flange 22 and the lower flange 32 from both sides thereof. By pressing, the lower flange 22 and the lower flange 32 may be pressed against each other, whereby the protrusion 34 may be crushed.

  Further, although the vehicle body member 10 is a cowl top side provided with the cowl top side inner 12 and the cowl top side outer 14, it may be a member of another vehicle body.

  For example, in the modification of the first embodiment of the present invention shown in FIG. 3, the vehicle body member 10 includes a rear floor panel 52 and a rear side member 54 as an example of a first vehicle body component member and a second vehicle body component member.

  An outer flange 56, which is an example of a joint portion, extends from the end of the rear floor panel 52 on the vehicle width direction outer side toward the vehicle upper side. The rear side member 54 is joined to the outer flange 56 so as to face the outer flange 56. The vertical wall part 58 which is an example is formed. The vertical wall 58 is formed with a protrusion 64 that protrudes toward the outer flange 56, and an adhesive 66 is applied to a portion 58 </ b> A below the protrusion 64 in the vertical wall 58. Has been.

  FIG. 3 shows a state before the protrusion 64 is crushed after the rear floor panel 52 is assembled to the rear side member 54. About the process in which the protrusion 64 is crushed and the vertical wall part 58 and the outer side flange 56 are joined, it is the same as that of 1st embodiment of the above-mentioned this invention.

  Also in this modified example, since the protrusion 64 guards the adhesive 66 as in the first embodiment of the present invention described above, it is possible to prevent the outer flange 56 from scraping off the adhesive 66. . Further, the adhesive 66 can be brought into close contact with the outer flange 56 and the vertical wall portion 58 by crushing the protrusion 64 by pressing the outer flange 56 and the vertical wall portion 58 together. As described above, the desired bonding strength can be obtained for the outer flange 56 and the vertical wall portion 58.

  Moreover, in 1st embodiment of this invention, the cowl top side inner 12 as a 1st vehicle body structural member is assembled | attached to the cowl top side outer 14 as a 2nd vehicle body structural member by moving to the vehicle lower side. It was. However, the vehicle body member 10 may be configured to be assembled to the first vehicle body component member by moving the second vehicle body component member relative to the first vehicle body component member. You may be set as the structure assembled | attached to each other by moving both the 2nd vehicle body structural members.

  In the first embodiment of the present invention, the relative assembly direction (movement direction) of the cowl top side inner 12 with respect to the cowl top side outer 14 is the vehicle vertical direction. However, the vehicle body member 10 may have a configuration in which the other direction is an assembly direction of the first vehicle body component member with respect to the second vehicle body component member.
