Description

TECHNICAL FIELD

[0001] The technology disclosed in this specification relates to a vehicle skeletal structure. BACKGROUND

[0002] In Japanese Patent No. 7473018, a sunroof structure for a vehicle having a front sunroof and a rear sunroof is disclosed. The sunroof structure of Japanese Patent No. 7473018 has a pair of longitudinal beams extending in a vehicle front-rear direction on both sides of a sunroof in a vehicle width direction, and a plurality of cross beams extending in the vehicle width direction and linking the pair of longitudinal beams. In addition, the sunroof structure of Japanese Patent No. 7473018 has an opening reinforcement member combined with the longitudinal beams. SUMMARY

[0003] In the sunroof structure of Japanese Patent No. 7473018, a case where the strength is reduced if the opening area of the sunroof is increased is considered. If the strength of the sunroof structure is reduced, it can be possible to make the vehicle easily deform at the time of a collision. Therefore, the present specification provides a technology capable of increasing the opening area of a roof opening portion and suppressing deformation of the vehicle at the time of a collision.

[0004] A first mode of the present technology relates to a vehicle skeletal structure of a vehicle having a roof opening portion. The vehicle skeletal structure has a pair of longitudinal beams extending in a vehicle front-rear direction on both sides of the roof opening portion in a vehicle width direction, a plurality of cross beams extending in the vehicle width direction and linking the pair of longitudinal beams, and a pair of reinforcement members extending in the vehicle front-rear direction on both sides of the roof opening portion in the vehicle width direction, disposed at positions inward of the pair of longitudinal beams in the vehicle width direction, the reinforcement members having a plurality of combined portions extending in the vehicle width direction and combining the reinforcement members with the plurality of cross beams.

[0005] If based on this structure, by having the reinforcement members, even if the opening area of the roof opening portion is increased, it is possible to maintain the strength of the vehicle skeletal structure. In addition, by the reinforcement members having a plurality of combined portions extending in the vehicle width direction, it is possible to effectively transmit a load acting on the vehicle between the reinforcement members and the cross beams.

[0006] In a second mode, based on the above first mode, the reinforcement members have a plurality of curved portions curved in a vehicle up-down direction.

[0007] In a third mode, based on the above first or second mode, the vehicle skeletal structure further has a center pillar extending in the vehicle up-down direction and supporting the longitudinal beams, the plurality of cross beams have a front cross beam disposed at a position on a front side of the center pillar and a rear cross beam disposed at a position on a rear side of the center pillar, and the roof opening portion is provided between the front cross beam and the rear cross beam.

[0026] One of the pair of reinforcing members 30 is positioned on the right side of the vehicle 4 in the vehicle width direction, and the other of the pair of reinforcing members 30 is positioned on the left side of the vehicle 4 in the vehicle width direction. The pair of reinforcing members 30 are spaced apart in the vehicle width direction. One of the pair of reinforcing members 30 is positioned on the right side of the roof opening 8 in the vehicle width direction, and the other of the pair of reinforcing members 30 is positioned on the left side of the roof opening 8 in the vehicle width direction. One of the reinforcing members 30 (left reinforcing member 30a) is positioned on the left outer side of the roof opening 8 in the vehicle width direction, and the other reinforcing member 30 (right reinforcing member 30b) is positioned on the right outer side of the roof opening 8 in the vehicle width direction. The pair of reinforcing members 30 are positioned in the vehicle width direction closer to the inner side of the pair of longitudinal beams 10. Each reinforcing member 30 is joined to each longitudinal beam 10, for example, by welding.

[0027] A pair of reinforcing members 30 are disposed between the front crossbeam 12 and the rear crossbeam 13 in the longitudinal direction of the vehicle. Each of the left and right reinforcing members 30 extends along the left and right longitudinal beams 10 in the longitudinal direction of the vehicle.

[0028] The main body 32 extends along the longitudinal direction of the vehicle. The main body 32 extends from a position further forward than the center pillar 16 to a position further rearward than the center pillar 16 in the longitudinal direction of the vehicle.

[0029] like Figure 4 As shown, when viewed in a cross-section orthogonal to the vehicle's longitudinal direction, the main body 32 is constructed of a curved plate-like component. The main body 32 extends in a curved manner along the vehicle width direction, inside the longitudinal beam 10 in the vehicle width direction. The main body 32 is curved in multiple sections. The main body 32 includes one or more first curved sections 34 that curve upwards, one or more second curved sections 36 that curve downwards, and one or more third curved sections 38 that curve laterally. The main body 32 is positioned to cover the vehicle width end of the roof opening 8. The main body 32 is positioned to cover the lower surface of the vehicle width end of the roof glass panel 22.

The rear joint portion 42 is joined to the rear crossbeam 13, for example, by welding. The rear joint portion 42 is welded to the rear crossbeam 13 at multiple locations. In a modified example, the rear joint portion 42 may also be joined to the rear crossbeam 13 by fasteners such as bolts.

[0032] (Effect)

[0033] The vehicle frame structure 2 of the embodiment has been described above. As can be seen from the above description, the vehicle frame structure 2 has a pair of reinforcing members 30 extending in the vehicle's longitudinal direction on both sides of the roof opening 8. The pair of reinforcing members 30 are positioned inside the vehicle's longitudinal direction, closer to the longitudinal beams 10. Each reinforcing member 30 has multiple connecting portions (front connecting portion 40, rear connecting portion 42), which extend in the vehicle's width direction and connect the reinforcing member 30 to multiple crossbeams 12, 13.

[0034] Based on this structure, the strength of the vehicle frame structure 2 can still be maintained even if the opening area of ​​the roof opening 8 is increased by having the reinforcing member 30. In addition, by having multiple joints (front joint 40 and rear joint 42) extending along the vehicle width direction, the load acting on the vehicle 4 can be effectively transferred between the reinforcing member 30 and the multiple crossbeams 12 and 13.

[0035] The reinforcing member 30 has multiple curved portions 34, 36 that bend in the vertical direction of the vehicle. Based on this structure, the energy of the load acting on the vehicle 4 can be effectively absorbed by the reinforcing member 30.

[0036] The vehicle frame structure 2 includes a center pillar 16 extending in the vertical direction of the vehicle and supporting the longitudinal beams 10. The vehicle frame structure 2 includes a front crossbeam 12 positioned forward of the center pillar 16 and a rear crossbeam 13 positioned rear of the center pillar 16. A roof opening 8 is provided between the front crossbeam 12 and the rear crossbeam 13. Based on this structure, the distance between the front crossbeam 12 and the rear crossbeam 13 in the longitudinal direction of the vehicle can be increased, thereby increasing the opening area of ​​the roof opening 8.

[0037] The specific examples of the present invention have been described in detail above, but these are merely illustrative and do not limit the scope of the claims. The technology described in the claims includes various modifications and alterations to the specific examples illustrated above. The technical elements described in this specification or drawings exert their usefulness individually or in various combinations, and are not limited to the combinations described in the claims at the time of application. Furthermore, the technologies illustrated in this specification or drawings are technologies capable of achieving multiple objectives simultaneously, and achieving one of these objectives is itself a useful technical achievement.
