[Problem that the idea aims to solve]

However, according to this structure, as shown in FIG. The longitudinal cross-section of the inner panel 100 is uniform along the vehicle width direction. Because of this, the rigidity is also uniform. Therefore, for example, if a load is applied to the vehicle from above, When the deformation mode of the windshield header inner panel 100 is not constant, 9, the maximum displacement of the windshield header inner panel 100 Sometimes the position is the part seen by the arrow A, and sometimes it is the part seen by the arrow B. maximum change If the position is in the direction shown by the arrow A or the direction shown by the arrow B, the windshield header Since the distance between the interior side of the inner panel 100 and the passenger head position 114 is narrowed, Conventionally, the above distance narrows even when a load is applied to the vehicle from above. The occupant head position 114 of the windshield header inner panel 100 Adding reinforcement material nearby or changing the thickness of the windshield header inner panel 100 By taking measures such as increasing the thickness of the windshield header inner panel 100. The amount of displacement was suppressed.

[0005] Considering the above facts, the present invention is designed to replace the windshield header inner panel after deformation. By setting the predetermined deformation mode, the occupant head position and windshield head alignment can be changed. Obtain a vehicle body structure that can prevent the distance from the na panel from narrowing. That is the purpose.

[0006]

[Means to solve the problem]

The body structure of the vehicle according to the present invention is arranged at the upper part of the front end of the passenger compartment along the width direction of the vehicle. The windshield header inner panel and this windshield header a weakened portion provided at a predetermined position along the vehicle width direction of the inner panel; It is characterized by.

[0007]

[Effect]

According to the above configuration, the windshield header inner panel has a The weak parts are provided at predetermined positions along the body of the vehicle according to the present invention. When a load is applied from above to a vehicle to which the structure is applied, this load is applied to weak parts. Concentrating on this, first deform the windshield header inner panel at this weak point. let Therefore, this weakened part may cause the windshield header inner to become damaged after deformation. The panel will deform in a predetermined deformation mode. Here, as an example, This can be avoided by providing the windshield header inner panel at both ends in the vehicle width direction. Since the amount of displacement in the area increases, the head position of the occupant sitting on the seat and The distance between the windshield header and the inner panel will no longer narrow.

【Example】

Figure 3 shows a part of the vehicle body to which the body structure according to the present invention is applied, namely the window. A portion centered around the shield header inner panel 10 is shown. In addition, this figure The arrow FR, which is shown as appropriate in the above, is toward the front of the vehicle, the arrow UP is toward the upper side of the vehicle, and the arrow I is toward the vehicle. N indicates the interior side of the vehicle.

[0009] The roof panel 12 (in FIG. 3, the middle part in the vehicle width direction is shown) A windshield glass (not shown) is installed on the front side of the vehicle, and a Roof side rails are provided on the lower side of the vehicle at both ends in the vehicle width direction of the roof panel 12. 14 are arranged. The roof side rail 14 is bent in multiple stages to straighten the longitudinal direction. The roof side rail outer panel 16 has a substantially semicircular corner cross section, and A roof side rail-in whose ends are bent away from each other to form a roughly dish-like shape. the outer panel 17, the roof side rail outer panel 16, and the roof side rail The reins are sandwiched to divide the closed cross section formed by the inner panel 17. It is equipped with a force (not shown), and these three parts can be welded together. It is composed of The upper side of the vehicle of this roof side rail outer panel 16 An end portion of the roof panel 12 in the vehicle width direction is welded to the surface.

0010 A windshield is provided on the lower side of the vehicle at the front end of the roof panel 12. A header inner panel 10 is arranged. As also shown in Figure 1, the window The shield header inner panel 10 has a bottom wall 10A, and the vehicle A front vertical wall 10B whose both ends in the longitudinal direction are bent toward the upper side of the vehicle; It has a rear vertical wall 10C. In addition, on the vehicle of the front vertical wall 10B and the rear vertical wall 10C. The side ends are further bent in the direction away from each other (vehicle longitudinal direction) to form the front end. 10D and a rear end portion 10E. Windshield header inner panel 1 0 is arranged with the vehicle width direction as the longitudinal direction, and the cross section perpendicular to the longitudinal direction is approximately dish-shaped. has been done.

[0011] The front end 10D of the windshield header inner panel 10 is connected to the roof panel 1. It is welded to the lower surface of the vehicle at the front end of No. 2 (see FIG. 2). Also, Edge of vehicle width direction of India shield header inner panel 10 and roof side rail Header reinforcement 18 is bridged between 14 and welded to each other for reinforcement. has been done.

0012 Now, as shown in Figures 1 and 2, the wind seal configured in this way The header inner panel 10 has a header inner panel near both ends in the longitudinal direction. A pair of the Fragile parts 20 and 22 (4 locations in total) are provided. located at the rear of the vehicle The weakened portion 22 is provided on the bend line between the rear vertical wall 10C and the bottom wall 10A, and By stamping and forming the curved line diagonally from the inside of the vehicle to the outside of the vehicle. It is formed by bending a square plate material along one diagonal at a predetermined angle. Note that the other vulnerable parts 20 are configured in the same way, so their explanation will be omitted. Ru.

[0013] In addition, the line connecting the ridge lines of the pair of weak parts 20 and 22 is a straight line, and this straight line is It matches the front and back direction of the vehicle. Shows the state cut along the line connecting the ridgelines. As can be seen from Fig. 2, the wind seam The roof header inner panel 10 has a changed longitudinal cross-sectional shape, and is similar to the roof panel. The cross-sectional area surrounded by the windshield header inner panel 10 is also It is smaller than the cross-sectional area in the general plane.

[0014] The operation of this embodiment will be explained below assuming that a load is applied to the vehicle from above. I will clarify.

[0015] When a load is applied to the vehicle from above, this load is applied to the roof panel 12 and the roof. The force is concentrated in the vicinity of the joint with the side rail 14 and applied generally in the width direction of the vehicle. And this The load is applied to the windshield header inner panel via the roof side rail 14. 10 along its longitudinal direction. Here, in this example, the wind seam A pair of weak parts 20 and 22 are provided near both ends of the header inner panel 10 in the vehicle width direction. are provided respectively, so that when the load is applied, the side to which the load is first applied is weakened. The parts 20 and 22 are bent along these ridge lines and absorb this load to some extent. Ru. As a result, the deformation mode of the windshield header inner panel 10 after deformation is determined. As shown in Fig. 4, the maximum displacement position is the part seen by the arrow C (the weak part). 20 and 22) and the occupant's head position 24. be able to. Therefore, when the load is applied, the windshield header inner Even if the panel 10 is deformed, the safety of the occupants can be ensured. In addition, in Figure 4 The windshield header inner panel 10 before deformation is a solid line, and the windshield header inner panel 10 after deformation is a solid line. The shield header inner panels 10 are each shown in broken lines.

[0016] In addition, the amount of displacement of the windshield header inner panel 100 is suppressed as in the conventional case. Since there is no need for reinforcing materials etc. for the This can contribute to reducing vehicle weight. Furthermore, it also leads to cost reduction.

[0017] In addition, in this example, a square plate material is bent diagonally at a predetermined angle. Although the formed fragile parts 20 and 22 are used, the present invention is not limited to this, and when the load is applied to the vehicle, etc. The windshield header will surely deform at that location due to the load of Apply to all configurations where the deformation mode of the na panel 10 is constant. I can do it.

[0018] For example, as shown in Figures 5 and 6, depending on the car model, the windshield The bottom wall portion 26A of the inner panel 26 has a substantially rectangular shape that is convex toward the upper side of the vehicle. A body-shaped bulge 28 is provided near the end of the bulge 28 on the outside of the vehicle interior. A configuration in which a pair of convex portions 30 and 32 are formed may be used. The convex parts 30 and 32 are bulging parts Rectangular surface portions 30A and 32A located continuously on the same plane as the surface on the upper side of the vehicle of No. 28. Both side portions 30B are bent and suspended from both ends in the width direction of the rectangular surface portions 30A and 32A. , 32B. Note that the positions where these convex portions 30 and 32 are provided are as follows. This is the same as the weakened parts 20 and 22 described above. Also with this configuration, the convex portions 30, 32 The cross-sectional shape of the windshield header inner panel 10 changes at the location where the windshield header inner panel 10 is provided. Therefore, the deformation mode of the windshield header inner panel 26 after deformation is is the same as the case shown in FIG. 4, and the distance between the maximum displacement position and the occupant head position 24 will be widely secured.

[0019] In addition, the windshield header inner panels 10 and 26 have fragile parts 20 and 22. Instead of providing the convex portions 30 and 32, cutouts, thin-walled portions, small holes, slits, etc. may be provided. However, the same effect can be obtained.

[0020] Furthermore, in the present embodiment and the modified example, the pair of weak parts 20 and 22 and the pair of convex parts 3 0 and 32 are provided on the same straight line along the front and rear direction of the vehicle, but depending on the car model, Either one of the fragile parts 20, 22 or one of the convex parts 30, 32 should be placed on the outside of the vehicle. Alternatively, it may be provided offset to the inside of the vehicle.
