Next, the connection structure of the center pillar 10 will be described. The upper end of the inner panel 11 of the center pillar 10 is joined and fixed by welding in a state where it is joined to a predetermined position of a roof side rail inner 5A which is a component of the roof side rail 5, and the lower end is a component of the side sill 6. The side sill inner 6A is joined and fixed by welding in a state where it is joined to a predetermined position. In this state, an inner hose 1 is provided on the outer side of the inner panel 11 in the vehicle body.
2. The phosphorus hose upper 13 and the outer panel 14 are arranged to face each other.

The front and rear connecting surfaces 12 of the inner hose 12 are provided on the outer surface of the vehicle body at the central portion 11A of the inner panel 11.
B, 12C are arranged such that the inner side surfaces of the vehicle body are in contact with each other, and in that state, spot welding is performed at predetermined positions of the central portion 11A, the front joint surface 12B, and the rear joint surface 12C, for example, the central portion 11A and the front joint surface 12B. Position and central part 11A
A spot tip for welding (not shown) is opposed to the welding position which is set so that the spot welding position between the inner joint 11 and the rear joining surface 12C is at an alternate height. And fixed to each other by spot welding. In this state, a portion between the front side portion 12D and the rear side portion 12E, which is the width of the inner hose 12 in the lateral direction, is accommodated between the front side portion 11B and the rear side portion 11E of the inner panel 11. The front side 11B of the panel 11 and the front side 12B of the inner hose 12 or the rear side 11E of the inner panel 11 and the rear side 12E of the inner hose 12 are in contact with each other with a slight distance. Absent.

The front and rear flanges 13D, 11D of the front and rear flanges 11D, 11E of the front and rear flanges 11D, 11E of the inner panel 11, to which the inner hose 12 is inserted and inserted, are fixed. 13E, the front and rear flanges 1 of the outer panel 14 are provided in front of the phosphorus hose upper 13 and on the vehicle outside surfaces of the rear flanges 13D and 13E.
In a state in which the inner surfaces of the vehicle body 4D and 14E are in contact with each other, predetermined portions of the front flanges 11D, 13D and 14D and the rear flanges 11E, 13E and 14E of the respective members are joined and fixed by welding to form the outer panel 14. Between the upper end and the lower end of the inner panel 11 via the phosphorus hose upper 13.

The upper end of the outer panel 14 is joined and fixed by welding in a state where it is joined to a predetermined position of a roof side rail outer 5B which is a component of the roof side rail 5. The lower end is joined and fixed by welding in a state where it is joined to a predetermined position of a side sill outer 6B which is a constituent member of the side sill 6. In FIG. 3E, the outer panel 14 is not shown, and the reference numeral 17 indicates a double center pillar inner.

Next, a case where an impact is applied from the side of the vehicle body provided with the coupling structure of the center pillar 10 will be described. In the longitudinal direction of the thick innerline hose 12, a protruding portion 12A protruding toward the outside of the vehicle body and front and rear side portions 12D and 12E formed on both sides thereof by being bent toward the outside of the vehicle body. Thus, an effective section modulus having many bending points is maintained. This inner hose 12
A thick-plate phosphorus hose upper 13 is further disposed outside the vehicle body, thereby increasing the drag from the upper portion of the inner panel 11 to a position slightly below the intermediate portion. On the other hand, the outer panel 14, which is the outermost shell of the center pillar 10, is formed by bending a relatively thin sheet like the inner panel 11, so that the upper to middle portions and the middle to lower end portions of the center pillar 10 are formed. An intensity difference will result.

As a result, an impact is applied from the side of the vehicle body, and the center pillar 10 is moved to the side door or the side sill 6.
When deforming and approaching the inside of the car body together with such a structure, first, the thin outer panel 14 starts to deform,
Since the rigidity of the upper portion to the middle portion of the center pillar 10 is increased by the slightly thicker inner hose 12 and the thicker hose portion 13, the amount of deformation of the upper portion to the middle portion of the inner panel 11 is minimized. Can be stopped. On the other hand, the inner panel 1 from the slightly lower position to the lower end of the intermediate portion where the inner hose 12 does not extend.
The rigidity of the outer panel 14 is hardly increased, and the rigidity of the outer panel 14 is maintained at substantially the same level as that of the conventional art.
Then, when the inner panel 11 itself, in which the deformation of the upper to middle portions, that is, the portion facing the window shoulder is prevented, attempts to enter the center direction of the vehicle body, the front and rear side portions 11 of the inner panel 11 are moved.
B and 11C are the front and rear side portions 12 of the inner hose 12.
Since the inner panel 11 only restricts the crushing of the cross section of the inner hose 12 while opposing the inner and outer faces D and 12E, the inner panel 11 absorbs the impact force at the time of a side collision by increasing the amount of deformation in the vertical extension direction. And the inner panel 11
There is no change in the coupling structure between the inner panel 11 and the roof side rail inner 5A and the side sill inner 6A, so that the inner panel 11 can enter the vehicle interior stably while suppressing deformation of the inner panel 11 itself.

As described above, according to the first embodiment of the present invention, the inner panel 11 of the center pillar 10 has the central portion 11A recessed by a predetermined distance toward the inside of the vehicle body.
A front hat portion 11B and a rear portion 11C sandwiching the central portion 11A from the vehicle front-rear direction are integrally bent and formed along the longitudinal direction, and have a substantially hat-shaped cross-sectional shape opened toward the outside of the vehicle body. Have. The extension distance of the slightly thick innerlin hose 12 inserted and inserted along the longitudinal direction of the central portion 11A is slightly lower than the upper rear door hinge mounting portion 15 formed at a predetermined position of the outer panel 14. It is possible to stiffen the slightly lower position of the upper to middle portions of the inner panel 11, that is, the vicinity of the window shoulder facing portion. Further, in the longitudinal direction of the inner hose 12, a protruding portion 12A protruding toward the outside of the vehicle by a predetermined distance, and front and rear side portions 12D and 12B which are bent toward the outside of the vehicle, respectively.
When the impact force is applied at the time of a side collision, the cross sections of the outer panels 14 are crushed and deformed toward the inside of the vehicle body without being affected by the shape of the outer panel 14. Can be absorbed. Furthermore, the inner panel 11 and the inner hose 12
Are located at different heights in the longitudinal direction of the vehicle body with respect to the central portion 11A, so that the inner hose 12 is not restricted by the crushing deformation and the amount of deformation in the vertical stretching direction is not restricted. Can be increased, and the impact force at the time of a side collision can be further absorbed. Further, a thick-plated phosphorus hose upper 13 is arranged outside the vehicle body of the inner hose 12, so that the upper and middle portions of the inner panel 11 are slightly lower, that is, a position corresponding to a window shoulder of a door. Drag can be further increased.

As a result, the outer panel 14, which is the outermost shell of the outer panel 10, can be made thin, and a difference in strength between the upper to middle portions and the middle to lower end portions of the center pillar 10 is generated. Since there is no significant change in the coupling structure between the center pillar 10 and the roof side rails 5 and the side sills 6, even when the center pillar 10 itself attempts to enter the center of the vehicle body due to the impact force at the time of a side collision, the center pillar 10 While increasing the amount of deformation toward the lower end to absorb the impact force,
The portion below the waist of the occupant is largely shifted inward of the vehicle body, so that the impact force can be prevented from directly reaching the occupant, and the center pillar 10 can be stably advanced toward the center of the vehicle body while suppressing deformation of the center pillar 10 itself. Will be able to do it. Furthermore, since the thickness of each member disposed outside the vehicle body of the center pillar 10 is set to be different from each other and is not unnecessarily strong, the weight cost can be reduced, and the side doors (front door, rear door) can be reduced. )
And the vehicle body can absorb the impact force in a well-balanced manner, preventing excessive deformation of the door ring into which the side door is fitted when the impact force is applied from the side, and the side door after the collision Can also be improved. Furthermore, since only the front and rear joining surfaces 12B and 12C of the inner hose 12 are formed so as to be in contact with the central portion 11A of the inner panel 11, workability and welding accuracy can be improved.

As a result, the safety of the occupant can be improved by effectively deforming the vehicle body from the impact force from the side of the vehicle body.
