- the case where the external load F acts on the pillar member 10 from the side of the vehicle body will be described.
- the case where the external load F acts on the pillar reinforcing member 30 from the upper side can be similarly described.
- an external load F acts on the pillar member 10 from the side of the vehicle body when a side collision occurs. Then, as shown in FIG. 4B, a part of the external load F is absorbed by the deformation of the pillar member 10. The external load F that has not been absorbed is transmitted from the upper part of the pillar member 10 to the pillar reinforcing member 30 (a similar phenomenon occurs in the roof side rail 40).

It has been.
- the external load F transmitted to the pillar reinforcing member 30 is absorbed by the deformation of the pillar reinforcing member 30.
- the pillar reinforcing member 30 is deformed by moving the hook-like member 32 through the hook hole 22 to the roof reinforcing member 20 in at least one of the vehicle width direction, the vehicle height direction, and the vehicle body front-rear direction (vehicle width direction in FIG. 4).
- the external load F that has not been absorbed is transmitted to the roof reinforcing member 20 as the axial forces A1 and A2 through the bolt 31 and the hook-shaped member 32, and the bending moment with the bolt 31 and the hook-shaped member 32 as a fulcrum.
- the movement of the pillar reinforcing member 30 with respect to the roof reinforcing member 20 is restricted within a predetermined range by the protruding portion 32a and the bent portion 32b of the hook-like member 32, the vehicle width direction, the vehicle height direction, and the vehicle body longitudinal direction are restricted.
- At least one of the external load F can be reliably transmitted from the pillar reinforcing member 30 to the roof reinforcing member 20.
- energy absorption absorption of external load F
- the bending moment M acting on the pillar reinforcing member 30 receives a reaction force due to the rigidity (tension) of the intermediate portion 34 between the bolt 31 and the hook-shaped member 32 in the pillar reinforcing member 30.
- the intermediate portion 34 between the pillar reinforcing members 30 is constrained at four or more points. Bending rigidity can be increased by surface force (tension). In particular, by providing a bead B or the like in the intermediate portion 34, the bending rigidity can be increased.
- the external load F that is not absorbed by the deformation of the pillar reinforcing member 130 is the bolt 131. Is transmitted to the roof reinforcing member 120 as an axial force A1 ′, and acts on the pillar reinforcing member 130 (and the roof reinforcing member 120) as a bending moment M ′ with the bolt 131 as a fulcrum. For this reason, in the vehicle body superstructure shown in FIG. 5, the external load F that is not absorbed by the deformation of the pillar reinforcing member 130 cannot be reliably transmitted from the pillar reinforcing member 130 to the roof reinforcing member 120.
- the pillar reinforcing member 130 resists the bending moment M ′ with the bolt 131 as a fulcrum, but since the fulcrum of the bending moment M ′ is one point of the bolt 131, it is easily bent. That is, only a small bending rigidity can be secured at the upper portion of the pillar member 110 by generating a reaction force with respect to the external load F acting on the pillar member 110 with the bolt 131 as an applied point.
- the hook-shaped member 32 is applied to the roof reinforcing member 20. Since it stops, the load transmission efficiency from the pillar reinforcement member 30 to the roof reinforcement member 20 can be improved.
- the bolt 31 and the hook-like member 32 of the pillar reinforcing member 30 are used as the application point, thereby reinforcing the pillar by increasing the thickness.
- the bending rigidity of the upper part of the pillar member 10 can be ensured without increasing the cross-sectional force of the member 30.
- the hooking portion (hook-like member 32) is hooked on the roof reinforcing member 20. Since it stops, the load transmission efficiency from the pillar reinforcement member 30 to the roof reinforcement member 20 can be improved. Moreover, since the latching
- the joint portion (bolt 31) is provided at a position different from the hook portion (hook-like member 32) in the vehicle width direction, an intermediate portion between the hook portion and the joint portion of the pillar reinforcing member 30 is provided. It becomes difficult to bend, and the bending rigidity of the upper part of the pillar member 10 can be secured.
- the protrusion 32a and the bent portion 32b restrict the movement of the pillar reinforcing member 30 in the vehicle width direction and the vehicle height direction, the load transmission efficiency can be further improved. Further, when the vehicle body superstructure is assembled, the pillar reinforcing member 30 can be easily aligned with the roof reinforcing member 20.
- the latching portion (hook-like member 32) is provided on the inner side in the vehicle width direction than the joint portion (bolt 31), the external load F acting from the side or upper side of the vehicle body is provided on the outer side in the vehicle width direction. It becomes easy to transmit to a junction part, and transmission of external load F to a latching part can be reduced.
- the above-described embodiment describes the best embodiment of the vehicle body upper structure according to the present invention, and the vehicle body upper structure according to the present invention is not limited to the one described in this embodiment. .
- the vehicle body superstructure according to the present invention may be obtained by modifying the vehicle body superstructure according to the present embodiment or applying it to other structures without departing from the gist of the invention described in each claim.
