[First embodiment]
First, a first embodiment of the present invention will be described.

  The vehicle body member 10 shown in FIG. 1 is applied with the vehicle body member joining structure S1 according to the first embodiment of the present invention, and constitutes a part of the vehicle body. The vehicle body member 10 includes a pair of vehicle body panels 12.

  The pair of vehicle body panels 12 each have a flange 14, an intersecting wall portion 16, and a side wall portion 18. The pair of vehicle body panels 12 are configured symmetrically in a direction intersecting with a flange 14 described later, that is, in the Y direction.

  The flange 14 extends along the edge 12 </ b> A of the vehicle body panel 12 (extends in the X direction), and the intersecting wall portion 16 intersects (perpendicularly) the flange 14 from the base end portion of the flange 14. It extends in the (Y direction). Further, the side wall 18 extends from the end of the intersecting wall 16 opposite to the flange 14 in the direction in which the flange 14 extends and in the direction orthogonal to the direction intersecting with the flange 14 (Z direction). .

  The pair of flanges 14 are bonded by an adhesive 20 from one end side to the other end side in the extending direction, and are welded at a plurality of spot welds 22 arranged at intervals in the extending direction. ing. That is, the pair of flanges 14 are joined to each other by the adhesive 20 and the plurality of welded portions 22 by spot welding.

  Further, in the intermediate portion between the end portion on the flange 14 side and the end portion on the side wall portion 18 side in the intersecting wall portion 16, a surplus length in which a cross section cut along the direction intersecting the above-described flange 14 forms a U shape. A portion 24 is formed. The surplus length portion 24 is formed so as to protrude on the side opposite to the side from which the flange 14 protrudes with respect to the intersecting wall portion 16.

  Further, the extra length portion 24 extends from one end portion 16A to the other end portion 16B of the intersecting wall portion 16 in the direction in which the pair of flanges 14 extend. As a result, the surplus length portion 24 overlaps the plurality of weld portions 22 in the direction in which the pair of flanges 14 extend.

  Although the entire pair of vehicle body panels 12 is not shown in FIG. 1, the pair of vehicle body panels 12 are also configured symmetrically in the direction in which the side wall portion 18 extends (Z direction). That is, each of the pair of vehicle body panels 12 is configured in a hat shape in cross section that opens to the other side. And a pair of vehicle body panels 12 comprised by this cross-sectional hat shape comprise the closed cross-section part 26 in the state mutually assembled | attached.

  Next, a method for joining body members according to the first embodiment of the present invention will be described.

  First, as shown in the upper diagram of FIG. 2, the adhesive 20 is applied to at least one of the pair of flanges 14. At this time, the adhesive 20 is applied from one end side to the other end side in the extending direction of the pair of flanges 14 (X direction in FIG. 1). Then, the pair of flanges 14 are opposed to each other, and the adhesive 20 is interposed between the pair of flanges 14 (first step).

  In addition, the extra length part 24 is previously formed in the cross wall part 16 at the time of shaping | molding of a pair of body panel 12. FIG.

  Subsequently, in a state in which the pair of side wall portions 18 are restrained by a jig or the like (not shown) (fixed in the Y direction), the pair of flanges 14 are mutually connected by the pair of spot guns 28 as shown in the lower diagram of FIG. Press to the side and spot weld. At this time, a plurality of welds 22 are formed at intervals in the extending direction of the pair of flanges 14 (second step).

  In addition, the surplus length part 24 is extended over the other end part 16B from the one end part 16A of the cross wall part 16 in the direction where a pair of flange 14 is extended (refer FIG. 1). Therefore, in the step of spot welding described above (second step), the pair of flanges 14 are spot-welded by the pair of spot guns 28 at a position overlapping the surplus length portion 24.

  For this reason, as described above, when the pair of flanges 14 are pressed toward each other by the pair of spot guns 28, as shown in the lower view of FIG. By extending 24, the pair of flanges 14 are easily brought together from the proximal end side to the distal end side.

  In the above manner, the pair of flanges 14 are joined by the adhesive 20 and the welded portion 22 by spot welding.

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

  As described above in detail, according to the first embodiment of the present invention, when the pair of flanges 14 are pressed toward each other by the pair of spot guns 28, the extra length portion formed in the intersecting wall portion 16. By extending 24, the pair of flanges 14 are easily brought together from the proximal end side to the distal end side. Thereby, since the welding part 22 by spot welding can be formed smoothly, the quality of this welding part 22 is securable.

  Moreover, since the cross-sectional shape of the surplus length portion 24 is U-shaped, when the pair of flanges 14 are pressed toward each other by the pair of spot guns 28, the surplus length portion 24 extends smoothly. Thereby, a pair of flange 14 can be match | combined still more easily from the base end side to the front end side.

  Further, since the extra length portion 24 is formed so as to protrude on the opposite side to the side from which the pair of flanges 14 protrude with respect to the intersecting wall portion 16, the pair of flanges 14 are welded by the pair of spot guns 28. In this case, the pair of spot guns 28 and the extra length portion 24 can be prevented from interfering with each other. Thereby, workability | operativity at the time of welding of a pair of flange 14 can be improved.

  Further, since the extra length portion 24 is formed from the one end portion 16A to the other end portion 16B of the intersecting wall portion 16 in the extending direction of the pair of flanges 14, the pair of flanges 14 are connected to each other by the pair of spot guns 28. When pressed to the side, the extra length portion 24 extends from one end portion 16A of the intersecting wall portion 16 to the other end portion 16B. Thereby, it can be set as the state which matched the pair of flange 14 uniformly from the one end side of the extending direction to the other end side.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.

  As shown in FIG. 3, the vehicle body member 10 joining method to which the vehicle body member joining structure S <b> 2 according to the second embodiment of the present invention is applied is the above-described vehicle body member joining according to the first embodiment of the present invention. The method is changed as follows.

  That is, as shown in the upper diagram of FIG. 3, at the time of molding the pair of vehicle body panels 12, the pair of flanges 14 are arranged so as to approach the mating flanges from the proximal end side toward the distal end side. 14 is inclined in advance with respect to a plane P orthogonal to the direction (Y direction) in which 14 faces.

  Then, as in the case of the first embodiment of the present invention described above, the adhesive 20 is interposed between the pair of flanges 14 (first step), and as shown in the lower diagram of FIG. The spot gun 28 is used to press the pair of flanges 14 toward each other for spot welding (second process).

  In this case, since the pair of flanges 14 are formed to be inclined in advance, even when the pair of flanges 14 are pressed toward each other by the pair of spot guns 28, the adhesive is outward from the tip side of the pair of flanges 14. It is suppressed that 20 protrudes. Thus, the fact that the pair of flanges 14 are formed in advance is equivalent to the protrusion suppressing means in the present invention.

  In addition, it can be judged from the external shape of the vehicle body member 10 after joining a pair of flange 14 whether it was spot-welded in the state which formed the pair of flange 14 inclining previously.

  That is, as shown in the lower drawing of FIG. 3, the pair of flanges 14 are joined in a state of being substantially parallel to each other by being pressed toward each other by the pair of spot guns 28 in the vicinity of the welded portion 22 by spot welding. ing.

  However, as shown in FIG. 4, the pair of flanges 14 come closer to the mating flanges from the proximal end side toward the distal end side, as shown in FIG. 4, at the intermediate portion between the welded portions 22 adjacent in the extending direction. Are joined in an inclined state. Therefore, it is possible to determine whether spot welding has been performed in a state in which the pair of flanges 14 are formed in advance by the presence or absence of an inclined portion between the welded portions 22 in the pair of flanges 14. Note that the inclination angle α of the pair of flanges 14 with respect to the plane P described above is smaller than the inclination angle β in the state before the spot welding described above.

  Next, with respect to the operation and effects of the second embodiment of the present invention, differences from the above-described first embodiment of the present invention will be described.

  As described above in detail, according to the second embodiment of the present invention, the direction in which the pair of flanges 14 face each other so that the pair of flanges 14 approach the other side flanges from the base end side toward the tip end side. Spot welding is performed in a state of being inclined in advance with respect to a plane P perpendicular to the line.

  Therefore, when the pair of flanges 14 are pressed toward each other by the pair of spot guns 28, the adhesive 20 can be prevented from protruding outward from the distal ends of the pair of flanges 14. Thereby, in addition to the quality of the welding part 22, the quality of the adhesion part by the adhesive agent 20 is also securable.

  Further, in order to suppress the adhesive 20 from protruding, it is only necessary to form the pair of flanges 14 at an angle. Therefore, an increase in manufacturing steps can be suppressed and the structure can be simplified, so that an increase in cost can be suppressed.

  In addition, when the pair of flanges 14 are formed so as to be inclined as described above, the pair of flanges 14 is more proximal on the proximal end side than on the distal end side (on the root side than on the terminal side). The gap between becomes larger. However, as described above, the surplus length portion 24 is formed in the intersecting wall portion 16. Therefore, when the pair of flanges 14 are pressed toward each other by the pair of spot guns 28, the extra length portions 24 extend, so that the base end sides of the pair of flanges 14 are easily combined. Can do.

  Next, a modification of the second embodiment of the present invention will be described.

  In the second embodiment of the present invention, as shown in FIG. 5, only one flange 14 of the pair of flanges 14 is flat so as to approach the other flange 14 as it goes from the proximal end side to the distal end side. You may incline in advance with respect to P.

  In this case, the surplus length portion 24 may be formed only in one of the pair of intersecting wall portions 16 that is connected to the proximal end portion of the one flange 14.

  As shown in FIG. 6, the vehicle body panel 12 having the other flange 14 that is not inclined among the pair of vehicle body panels 12 may be formed in a flat plate shape extending along the plane P described above.

  Further, as shown in FIG. 7, the surplus length portion 24 may be intermittently formed at a position overlapping the welded portion 22 in the extending direction of the pair of flanges 14.

  Even if comprised as mentioned above, there can exist an effect | action and effect similar to the effect | action and effect of above-mentioned 2nd embodiment of this invention.

  Further, as shown in FIG. 8, the extra length portion 24 may have a V-shaped cross section cut along a direction intersecting the flange 14 described above. With this configuration, in addition to the operation and effect when the surplus length portion 24 is formed in a U-shaped cross section, a ridge line portion 24 </ b> A extending along the pair of flanges 14 is formed at the bottom of the surplus length portion 24. Therefore, the rigidity of the vehicle body member 10 can be improved.

  In addition, if the extra length part 24 is a structure extended when a pair of flange 14 is pressed to the other side by a pair of spot guns 28, it is made into shapes other than a cross-sectional U shape or a cross-sectional V shape. Also good.

  Further, the extra length portion 24 having a U-shaped cross section, a V-shaped cross section, or the like has a sufficiently low height in the protruding direction so as not to interfere with the pair of spot guns 28, for example. In addition, the cross wall portion 16 may be formed so as to be convex on the side from which the pair of flanges 14 protrude.

[Third embodiment]
Next, a third embodiment of the present invention will be described.

  As shown in FIG. 9, the joining method of the vehicle body member 10 to which the joining structure S3 of the vehicle body member according to the third embodiment of the present invention is applied is the joining of the vehicle body member according to the above-described first embodiment of the present invention. The method is changed as follows.

  That is, as shown in the upper diagram of FIG. 9, when forming the pair of vehicle body panels 12, a bead 30 that protrudes toward the mating flange 14 is formed in advance on the distal end side of the pair of flanges 14. This bead 30 is an example of the protrusion part and the protrusion control means in the present invention.

  Then, as in the case of the first embodiment of the present invention described above, an adhesive 20 is interposed between the pair of flanges 14 (first step), and as shown in the lower diagram of FIG. The spot gun 28 is used to press the pair of flanges 14 toward each other for spot welding (second process).

  In this case, since the beads 30 projecting toward the mating flange 14 side are formed in advance at the distal ends of the pair of flanges 14, even when the pair of flanges 14 are pressed against each other by the pair of spot guns 28, The adhesive 20 is prevented from protruding from the tip side of the pair of flanges 14 to the outside.

  Since the bead 30 remains in a crushed state after the pair of flanges 14 are joined, as shown in the lower diagram of FIG. 9, as described above, the mating flange is provided at the distal end side of the pair of flanges 14. Whether or not spot welding is performed in a state where the beads 30 projecting toward the 14 side are formed in advance can be determined from the outer shape of the vehicle body member 10 after the pair of flanges 14 are joined.

  Next, the difference of the operation and effect of the third embodiment of the present invention from the above-described first embodiment of the present invention will be described.

  As described in detail above, according to the third embodiment of the present invention, spot welding is performed in a state in which the bead 30 protruding in the mating flange 14 side is formed in advance on the distal end side of the pair of flanges 14.

  Therefore, when the pair of flanges 14 are pressed toward each other by the pair of spot guns 28, the adhesive 20 can be prevented from protruding outward from the distal ends of the pair of flanges 14. Thereby, in addition to the quality of the welding part 22, the quality of the adhesion part by the adhesive agent 20 is also securable.

  Further, in order to prevent the adhesive 20 from protruding, it is only necessary to form the bead 30 on the tip side of the pair of flanges 14. Therefore, an increase in manufacturing steps can be suppressed and the structure can be simplified, so that an increase in cost can be suppressed.

  Next, a modification of the third embodiment of the present invention will be described.

  In 3rd embodiment of this invention, as FIG. 10 shows, the bending part 32 bent toward the other party flange 14 side may be previously formed in the front end side of a pair of flange 14. As shown in FIG. This bent part 32 is an example of the protrusion part and the protrusion suppression means in the present invention.

  Further, as shown in FIG. 11, the bent portion 32 may be formed only on any one of the pair of flanges 14.

  Since the bent portion 32 remains in a bent state even after the pair of flanges 14 are joined, as described above, with the bent portion 32 formed in advance on the distal end side of the pair of flanges 14, Whether or not spot welding has been performed can be determined from the outer shape of the vehicle body member 10 after the pair of flanges 14 are joined.

  Further, although not particularly illustrated, the above-described bead 30 may also be formed only on one of the pair of flanges 14.

  In addition, instead of the beads 30 and the bent portion 32 described above, the protrusion suppressing member configured separately from the pair of flanges 14 is at least one of the pair of flanges 14 as an example of the protruding portion and the protrusion suppressing means in the present invention. The flange 14 may be provided in advance on the tip side.

  Even if comprised as mentioned above, there can exist an effect | action and effect similar to the effect | action and effect of above-mentioned 3rd embodiment of this invention.
