The present invention relates to an adhesion flange structure.
Structures are known that include an upper side metal plate that is curved to form an upper wall portion and an upper side flange, and a lower side metal plate that is curved to form a lower wall portion and a lower side flange. The upper side flange and the lower side flange are joined together using an adhesive (see for example Japanese Patent Application Laid-Open (JP-A) No. 2006-167753).

However, in structures such as that described above, when for example a bend portion between the upper wall portion and the upper side flange is adhered to the lower side metal plate in a floating state positioned a specific dimension or greater from the lower side metal plate, a thickness of the adhesive is increased between the bend portion and the lower side metal plate, and the rigidity of the bend portion may not be secured.
In consideration of the above circumstances, a subject of the present invention is to provide an adhesion flange structure capable of securing the rigidity of a bend portion.
In order to address the above issues, an adhesion flange structure of the present invention includes: a first flange extending along an end portion of a first vehicle body panel, and formed at the end portion of the first vehicle body panel with a bend portion interposed therebetween; a second flange formed at an end portion of a second vehicle body panel that configures a section of a vehicle body together with the first vehicle body panel, the second flange facing the bend portion and the first flange; an adhesive that adheres the bend portion and the first flange to the second flange; and a ridge projection portion formed extending along a direction in which the first flange extends at the end portion of the first vehicle body panel, and formed to at least one portion out of the bend portion and a facing portion of the second flange that faces the bend portion, the ridge projection portion forming a projection towards another portion out of the bend portion and the facing portion.
According to this adhesion flange structure, the ridge projection portion is formed to at least one portion out of the bend portion and the facing portion of the second flange that faces the bend portion such that the ridge projection portion projects towards the other side out of the bend portion and the facing portion. The thickness of the adhesive between the bend portion and the facing portion can be reduced due to forming the ridge projection portion, thereby enabling the rigidity of the bend portion to be secured.
In the adhesion flange structure of the present invention, configuration is preferably made wherein the ridge projection portion is formed at both the bend portion and the facing portion.
By employing such a configuration, the thickness of the adhesive between the bend portion and the facing portion can be reduced even further, thereby enabling the rigidity of the bend portion to be further secured.
As has been described in detail above, the present invention is capable of securing the rigidity of the bend portion.
Explanation follows regarding an exemplary embodiment of the present invention.
A vehicle framework member 30 illustrated in
Namely, the first vehicle body panel 32 is formed with a side wall portion 36 that projects up with respect to the second vehicle body panel 34. An end portion at a second vehicle body panel 34 side of the side wall portion 36 is formed with a first flange 14 with a bend portion 12 interposed therebetween. The first flange 14 extends in an L direction along the end portion at the second vehicle body panel 34 side of the side wall portion 36. An end portion at a first flange 14 side of the second vehicle body panel 34 is formed with a second flange 16 facing the bend portion 12 and the first flange 14.
The bend portion 12 and the first flange 14 are adhered to the second flange 16 at substantially the entire region of the bend portion 12 and the first flange 14 using an adhesive 18. The first flange 14 and the second flange 16 are moreover joined together by spot welding at plural welding portions 20. The plural welding portions 20 extend in a row at intervals to each other along the extension direction of the first flange 14 along the end portion at the second vehicle body panel 34 side of the side wall portion 36, namely along the L direction.
The bend portion 12 described above is formed with a ridge projection portion 24 that projects towards a facing portion 22 side of the second flange 16 that faces the bend portion 12. The ridge projection portion 24 extends along the L direction described above.
Explanation follows regarding operation and advantageous effects of the exemplary embodiment of the present invention.
In order to clarify the operation and advantageous effects of the exemplary embodiment of the present invention, explanation is first given regarding Comparative Examples. Note that for ease of comparison, configuration elements that have the same names in the Comparative Examples as in the exemplary embodiment of the present invention are allocated the same reference numerals.
In adhesion flange structures 50, 60 of the Comparative Examples illustrated in
In the adhesion flange structure 50 of a first Comparative Example illustrated in
Moreover, in the adhesion flange structure 60 of a second Comparative Example illustrated in
However, when the first flange 514 is bent towards the second flange 16 side as in the adhesion flange structure 50 of the first Comparative Example illustrated in
When the first flange 14 is curved at plural locations as in the adhesion flange structure 60 of the second Comparative Example illustrated in
Since each of the bend portions 512 and 612 serving as a ridge line portion in the first vehicle body panels 532 and 632 is a location that readily affects the rigidity of the vehicle framework members 530 and 630, there is a concern that the rigidity of the overall vehicle framework member 3 may be decreased if the rigidity of the bend portions 512 and 612 is decreased.
Therefore, as illustrated in
Due to forming the ridge projection portion 24 at the bend portion 12 as described above, the amount by which the bend portion 12 is positioned floating away from the second flange 16 can be kept to within the specific dimension even when the first flange 14 is bent towards the second flange 16 side during spot welding.
Explanation follows regarding modified examples of an exemplary embodiment of the present invention.
In the exemplary embodiment of the present invention described above, the second vehicle body panel 34 is formed in a flat plate shape, however as illustrated in
The ridge projection portion 24 is formed to the bend portion 12 of the first vehicle body panel 32, however as illustrated in
Moreover, as illustrated in
The adhesion flange structures 10, 110, 210, 310 and 410 are applied to the vehicle framework member 30, however the adhesion flange structures 10, 110, 210, 310 and 410 may be applied to a vehicle body section other than the vehicle framework member 30.
In addition to adhering the first flange 14 and the second flange 16 together using the adhesive 18, the first flange 14 and the second flange 16 are also joined together by the plural welding portions 20, however the first flange 14 and the second flange 16 may be joined together using the adhesive 18 alone.
Explanation has been given above of an exemplary embodiment of the present invention, however the present invention is not limited to the above, and obviously various modifications may be implemented within a range not departing from the gist of the present invention.
