Hereinafter, embodiments of a vehicle roof structure according to the present invention will be described with reference to the drawings. In the figure, an arrow UP indicates the vehicle upper side, an arrow OUT indicates the vehicle width direction outer side, and an arrow FR indicates the vehicle front side.

  FIG. 1 is a perspective view of an upper portion of a vehicle to which the vehicle roof structure according to the first embodiment is applied. 2 shows a cross-sectional view taken along line AA of FIG.

  As shown in FIG. 1, the vehicle roof 10 includes a roof panel 30 covering the cabin and roof side rails 12 provided on both sides in the vehicle width direction. The roof panel 30 constitutes an outer plate of the vehicle. The roof side rail 12 is disposed along the vehicle front-rear direction as a pair of left and right vehicle body side structural members.

  As shown in FIG. 2, the roof side rail 12 is composed of three panels: a rail inner panel 14, a rail outer reinforcement 16, and a side outer panel 18. The rail inner panel 14 is disposed on the vehicle interior side, and the rail outer reinforcement 16 is disposed on the vehicle exterior side with respect to the rail inner panel 14. The rail inner panel 14 and the rail outer reinforcement 16 form a closed cross section. The side outer panel 18 is disposed on the outer side of the passenger compartment of the rail outer reinforcement 16. The rail inner panel 14, the rail outer reinforcement 16 and the side outer panel 18 are all made of a steel plate.

  The rail inner panel 14 includes a main body portion 14A that forms a closed cross-section with the rail outer reinforcement 16, an inner flange portion 14B that is bent substantially horizontally from the inner end portion of the main body portion 14A toward the vehicle width direction, The outer flange portion 14C is bent obliquely downward and outward from the outer end portion of the main body portion 14A.

  The rail outer reinforcement 16 includes a main body portion 16A that is disposed so as to face the main body portion 14A, an inner flange portion 16B that is bent substantially horizontally from the inner end portion of the main body portion 16A toward the inner side in the vehicle width direction, and a main body portion. The outer flange portion 16C is bent outward and obliquely downward from the outer end portion of 16A.

  The side outer panel 18 is bent substantially horizontally inwardly in the vehicle width direction from the inner end of the main body 18A and a main body 18A having a bulge capable of covering the main body 16A of the rail outer reinforcement 16 from the outside of the passenger compartment. The inner flange portion 18B and the outer flange portion 18C bent obliquely downward and outward from the outer end portion of the main body portion 18A.

  On the inner side in the vehicle width direction of the main body portion 18A, an upright portion 22 that is bent upward from the inner flange portion 18B is formed. From the upper end of the upright part 22, the junction part 24 is extended toward the vehicle outer side diagonally upward.

  Three pieces of the inner flange portion 14B of the rail inner panel 14, the inner flange portion 16B of the rail outer reinforcement 16 and the inner flange portion 18B of the side outer panel 18 are overlapped and joined by spot welding. Similarly, the outer flange portion 14C of the rail inner panel 14, the outer flange portion 16C of the rail outer reinforcement 16, and the outer flange portion 18C of the side outer panel 18 are overlapped and joined by spot welding. As a result, a vehicle skeleton member having a closed cross section extending along the vehicle longitudinal direction is formed on the roof side rail 12.

  The roof panel 30 is formed in a gently curved shape that is convex toward the vehicle upper side, and includes a roof main body 32 that covers the cabin from the vehicle upper side. Both end portions of the roof body portion 32 in the vehicle width direction are opposed to the inner flange portion 18B of the side outer panel 18. Further, both end portions of the roof panel 30 in the vehicle width direction are bent so that the front ends thereof are obliquely inwardly inward of the vehicle from the vehicle width direction outer ends of the roof main body portion 32 to form outer end bent portions 34. . The outer end bent portion 34 is disposed so as to face the joint portion 24 of the side outer panel 18, and a part of the outer end bent portion 34 is overlapped and abutted to form an abutting portion 26. The upper end of the joint portion 24 is disposed on the vehicle upper side than the upper surface of the roof main body portion 32. A sealer 28 is applied to the outside of the vehicle between the roof main body portion 32 and the joint portion 24.

  A closing member 40 is disposed between the inner end portion of the inner flange portion 18B in the vehicle width direction and the roof main body portion 32 facing the inner end portion. As shown in FIG. 3, the closing member 40 has a long plate shape, and is arranged such that the longitudinal direction L is along the vehicle front-rear direction and the plate thickness direction W is the vehicle width direction. The closing member 40 has one end side in the height direction H bonded to the inner flange portion 18 </ b> B and the other end side bonded to the lower surface of the roof main body portion 32. An adhesive tape 44 is used for bonding. The closing member 40 is continuously disposed over the entire length of the roof panel 30 in the vehicle front-rear direction. A closed space 42 surrounded by the roof main body 32, the outer end bent portion 34, the joint portion 24, the upright portion 22, the inner flange portion 18 </ b> B, and the closing member 40 is formed inside the contact portion 26. Yes. The closed space 42 is a closed space that straddles the contact portion 26.

  The closing member 40 is formed of foamed rubber, and is disposed between the inner flange portion 18 </ b> B and the roof main body portion 32 while being compressed in the height direction H. Therefore, as shown in FIG. 2, the width is shorter than that in the non-compressed state (see the two-dot chain line 40). The closing member 40 is formed with a filling slit 46. The filling slit 46 is formed at the center in the width direction of the closing member 40 so as to penetrate the plate thickness direction W along the longitudinal direction L and the plate thickness direction W. Before the adhesive 48 is filled into the closed space 42 by the filling slit 46, the closed space 42 is communicated with the outside through the filling slit 46. Here, “communication” means that the space does not necessarily have to be formed continuously, and the closed space 42 can be accessed from the outside. The filling slits 46 are provided at a plurality of locations on the closing member 40.

  The closed space 42 is filled with an adhesive 48. When the adhesive 48 is filled, the filling slit 46 is closed.

  Next, the operation and effect of this embodiment will be described.

  First, one end surface of the closing member 40 in the height direction H is bonded to the upper surface on the inner side in the vehicle width direction of the inner flange portion 18 </ b> B of the roof side rail 12 via the adhesive tape 44. A double-sided adhesive tape 44 is attached to the other end surface of the closing member 40 in the height direction H.

  When the roof panel 30 and the roof side rail 12 are joined, the roof panel 30 is disposed on the upper part of the body including the roof side rail 12. At this time, the outer end bent portion 34 is brought into contact with the joint portion 24 to form the contact portion 26. Further, the roof main body portion 32 is disposed on and adhered to the adhesive tape 44 of the closing member 40. The closing member 40 is compressed due to the weight of the roof panel 30. In this state, the aforementioned closed space 42 is formed at the end of the roof panel 30 in the vehicle width direction.

  Next, the nozzle 50 </ b> A of the adhesive application gun 50 is inserted into the filling slit 46 of the closing member 40, and the adhesive 48 is injected into the closed space 42. The adhesive 48 is injected by applying an injection pressure so that the closed space 42 is completely filled. After the injection, the nozzle 50A is pulled out and the filling slit 46 is closed. Then, a sealer 28 is applied to the vehicle outside of the contact portion 26.

  According to the present embodiment, since the closed space 42 is closed, it is possible to prevent the adhesive 48 from sagging and flow, and to supply a necessary amount of adhesive to a required location. In this way, by filling the closed space 42 with the adhesive 48, the bonding strength can be increased as compared with the case where the adhesive is simply applied and bonded in a thin film shape or a dot shape. Further, by using the adhesive in this way, the roof panel 30 and the roof side rail 12 can be joined without using a laser.

  Further, since the closing member 40 of the present embodiment has the filling slit 46, the closing space 42 can be easily accessed via the filling slit 46, and the filling work of the adhesive 48 can be performed. It can be done easily.

  Further, since the closing member 40 of the present embodiment is formed of a foamed rubber material that is relatively light and easily elastically deformed, the weight can be reduced and the adhesion between the roof panel 30 and the roof side rail 12 can be reduced. Can be secured.

  In the present embodiment, the adhesive 48 is injected into the closed space 42 after the roof panel 30 is disposed on the roof side rail 12. However, the adhesive 48 is supplied to some extent before the roof panel 30 is disposed. It may be left. In this case, the adhesive 48 is supplied to the space surrounded by the joint portion 24, the upright portion 22, the inner flange portion 18 </ b> B, and the closing member 40 (the space where the upper portion of the closed space 42 is opened). Then, after the roof panel 30 is arranged above the roof side rail 12, the shortage is injected into the closed space 42.

  Further, in the present embodiment, the closing member 40 is disposed over the entire length of the roof panel 30 in the vehicle front-rear direction, but is not necessarily disposed over the entire length. In order to locally secure the bonding strength between the roof panel 30 and the roof side rail 12, the closing member 40 may be disposed in a part of the vehicle front-rear direction.

  In this embodiment, the filling slit 46 is formed in the closing member 40. However, the filling slit 46 is not necessarily formed. In this case, a portion where the roof main body portion 32 and the closing member 40 are not bonded is formed in part, and the nozzle 50A of the adhesive application gun 50 is inserted from the non-bonded portion, and the closed space 42 is inserted. Adhesive 48 may be injected into the substrate.

  Further, the filling slit 46 of the present embodiment is a slit along the longitudinal direction L, but may be a slit along a direction intersecting the longitudinal direction L, for example, a direction orthogonal to the longitudinal direction L. Further, instead of the filling slit 46 of the present embodiment, as shown in FIG. 4A, a hole 46A into which the nozzle 50A of the adhesive application gun 50 can be inserted is formed, and the adhesive 48 is formed from the hole 46A. May be filled. Further, as shown in FIG. 4B, a notch for filling 46B is formed by cutting from one side edge in the height direction H of the closing member 40, and the adhesive 48 is removed from the notch for filling 46B. It may be filled.

  Moreover, in this embodiment, although the adhesive tape 44 was arrange | positioned at the both end surfaces of the height direction H of the closure member 40, the adhesive tape 44 is not necessarily required. Further, the adhesive tape 44 may be disposed only on one end surface of the closing member 40 in the height direction H. As in the present embodiment, by arranging the adhesive tape 44 on both end surfaces in the height direction H of the closing member 40, the roof panel 30 can be securely fixed temporarily on the roof side rail 12 to facilitate the subsequent work. can do.

  In the present embodiment, the closing member 40 is formed of a foamed rubber material, but may be formed of a member using other materials. However, it is preferably a lightweight and elastically deformable member.

  In the present embodiment, the adhesive strength and rigidity between the roof panel 30 and the roof side rail 12 can be adjusted by changing the cross-sectional area of the closed space 42 filled with the adhesive 48 in the vehicle width direction. As shown in FIG. 5, the cross-sectional area of the closed space 42 in the vehicle width direction is reduced by moving the adhesion position between the end surface of the closing member 40 on the roof panel 30 side and the roof body portion 32 to the outside in the vehicle width direction. Thus, the adhesive strength and rigidity can be lowered. On the other hand, as shown in FIG. 6, the cross-sectional area of the closed space 42 in the vehicle width direction is moved by moving the adhesion position between the end surface of the closing member 40 on the roof panel 30 side and the roof main body portion 32 inward in the vehicle width direction. Can be increased to increase the adhesive strength and rigidity.

As for the closing member, as shown in FIG. 7, a closing member 60 in which a partition portion 60 </ b> A is formed on the outer side in the vehicle width direction of the closing member 40 may be used. The partition 60A is formed along the height direction H of the portion formed by the closing member 40, and extends outward in the vehicle width direction. The partition 60A is formed at a predetermined interval in the longitudinal direction L. The closed space 42 is partitioned into a plurality of portions by the partition portion 60A.
As described above, by using the closing member 60 having the partitioning portion 60A, the strength of the closing member 60 in the height direction H can be increased, and can be stably placed on the roof side rail 12 before the adhesive 48 is filled. The roof panel 30 can be temporarily fixed.

A plurality of closed spaces 72 are formed in the longitudinal direction L of the closing member 70. The closing member 70 includes an outer wall portion 70A disposed at both ends of the closing space 72 in the vehicle width direction W, and a partition portion 70B that partitions the closing space 72 in the longitudinal direction L.

  The blocking member 70 is disposed between the inner flange portion 18B and the roof main body portion 32 facing the inner flange portion 18B so that the longitudinal direction L is along the vehicle longitudinal direction. The vehicle lower end surface of the closing member 70 (the vehicle lower end surface of the outer wall portion 70A and the partitioning portion 70B) is bonded to the inner flange portion 18B via the adhesive tape 44, and the vehicle upper end surface of the blocking member 70 is the adhesive tape 44. It is bonded to the lower surface of the roof main body 32 via

  As shown in FIG. 9, a closed space 72 is disposed on the vehicle inner side of the contact portion 26 so as to straddle the contact portion 26. The closed space 72 is closed by being surrounded by the roof main body portion 32, the inner flange portion 18B, the outer wall portion 70A, and the partition portion 70B.

  The closing member 70 is integrally formed of foam rubber. The closing member 70 is disposed between the inner flange portion 18 </ b> B and the roof main body portion 32 while being compressed in the vehicle height direction H. A filling slit 76 is formed in the outer wall portion 70A on the inner side in the vehicle width direction. The filling slit 76 penetrates the vehicle width direction W along the longitudinal direction L and the vehicle width direction W at the center in the vehicle height direction H of the outer wall portion 70A, similarly to the filling slit 46 of the first embodiment. It is formed as follows. One filling slit 76 is formed for each outer wall portion 70 </ b> B corresponding to each closed space 72.
