  In Patent Document 2, a filling member is provided in the vicinity of a corner of a space formed by the outer panel and the reinforcing panel, and a positioning step of the filling member is formed on the reinforcing panel, whereby the outer panel side surface portion of the reinforcing panel is provided. It is disclosed that a convex bead is formed on (FIG. 5B of Patent Document 2). It seems that this convex bead provides an effect of improving bending strength. However, since the convex bead of patent document 2 is comprised so that it may contact also with a filling member so that it may be for the purpose of positioning, in the initial stage of the collision of a side collision, an initial load is passed from an outer panel via a filling member. The convex bead is crushed and deformed substantially flatly, that is, there is no corner of the convex bead, and the bending strength improvement effect brought about by the corner may not be sufficiently obtained. It was.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle side body structure that can secure a bending strength against a side collision without crushing a reinforcing convex bead formed on a reinforcing panel of a pillar.

Reduced load is transmitted. In other words, by transmitting a load to the protruding portion of the reinforcing panel after a predetermined time from the initial stage of the collision, the shape of the corner portion is maintained without being crushed and the bending strength is improved. Strength can be improved.

  According to the second aspect of the invention, since the protruding direction of the protruding portion is the same direction as the bulging direction of the door hinge mounting portion, the change in the drawing depth of the reinforcing panel above the upper hinge mounting portion is moderated. It is possible to make it difficult to cause molding defects. Furthermore, by forming the protruding portion of the reinforcing panel continuously with the upper hinge mounting portion, no step or the like is formed between the protruding portion and the upper hinge mounting portion, so the deformation starting point for the load input from the door Therefore, without taking measures such as increasing the thickness of the reinforcing panel, that is, it is possible to reliably receive the load while having a lightweight structure.

  Further, according to the invention described in claim 3, when the distance between the outer surface of the reinforcing panel and the inner wall of the outer surface of the outer panel is L, and the height of the protrusion is H, H / L is 0.5 or more. By doing so, the corners of the protrusions can be used effectively, so that the bending strength of the center pillar can be improved satisfactorily.

As shown in FIG. 4, the reinforcing panel 30 is formed so as to extend in the vertical direction of the vehicle body, like the outer panel 10 and the inner panel 20.

  The reinforcing panel 30 is disposed substantially along the outer panel 10 and, as shown in FIG. 3, extends in the vehicle width direction from the outer surface portion 31 extending in the vehicle body front-rear direction and both end portions of the outer surface portion 31 in the vehicle body front-rear direction. A front vertical surface portion 32 and a rear vertical surface portion 33; a front flange portion 34 and a rear flange portion 35 extending in the vehicle body front direction and the vehicle body rear direction from the vehicle width direction inward ends of the vertical wall portions 32 and 33 on both sides; The outer surface portion 31 and the vertical surface portions 32 and 33 on both sides are provided with corner portions 36 and 37 on both sides and formed in a substantially hat-shaped cross section.

  Further, as shown in FIG. 3, a protruding portion 39 is formed on the outer surface portion 31 of the reinforcing panel 30. The projecting portion 39 extends inward in the vehicle width direction from both end portions of the projecting surface portion 40 in the front-rear direction of the vehicle body substantially along the outer panel 10, and extends to the basic surface portions 38, 38 of the outer surface portion 31. The connecting surface portions 41 and 41 before and after connecting are formed in a substantially U-shaped cross section.

  The reinforcing panel 30 is joined together in a state where the front flange portion 34 and the rear flange portion 35 are sandwiched between the front flange portions 14 and 24 and the rear flange portions 15 and 25 of the outer panel 10 and the inner panel 20, respectively. The outer panel 10 and the inner panel 20 are disposed.

  As shown in FIG. 3, the front filling member 50 and the rear filling member 51 serving as load transmitting members include a front corner portion 16, 36 and a rear corner portion 17 of the space formed by the outer panel 10 and the reinforcing panel 30. 37, the outer surface portion 11 of the outer panel 10 and the outer surface portion 31 of the reinforcing panel 30, the corner portions 16 and 17 on both sides of the outer panel 10, the corner portions 36 and 37 on both sides of the reinforcing panel 30, and the vertical portions on both sides of the outer panel 10. The surface portions 12 and 13 and the vertical surface portions 32 and 33 on both sides of the reinforcing panel 30 are in contact with each other, and do not contact the portions excluding the protrusion portions, that is, the protrusion portions 39 (the protrusion surface portion 40 and the connecting surface portion 41). Is provided. Further, as shown in FIG. 2, the lower end of the front filling member 50 and the rear filling member 51 in the vertical direction of the vehicle body is a portion where the protruding portion 39 and the inclined portion 44 are continuous (the boundary between the protruding portion 39 and the inclined portion 44. ) And substantially the same position.

  The filling members 50 and 51 may be heated foam materials, for example. This heat-foamed material is in the form of a sheet in an unfoamed state, and is pasted to the place where the filling members 50 and 51 are disposed on the surfaces near the corners 36 and 37 on both sides of the reinforcing panel 30 by an adhesive. It is done. The sheet-like heat foamed material is heated and foamed in a drying process after the entire vehicle body is immersed in the electrodeposition liquid in the electrodeposition coating process of the vehicle body, and is filled in the space.

  The front side filling member 50 and the rear side filling member 51 take into account the expansion ratio of the heating foam material and the direction of expansion due to foaming, and adjust the shape and affixed part of the heating foam material. The protruding surface portion 40 and the connecting surface portion 41) are arranged so as not to come into contact with each other. As a method for preventing the filling members 50 and 51 on both sides from coming into contact with the protruding portion 39 after heating and foaming, in addition to the above, the corner portions 36 and 37 on both sides of the reinforcing panel 30 and the connecting surface portions 41 and 41 on both sides are provided. A stepped portion may be provided in the middle so that the corners 36 and 37 on both sides are located on the inner panel 21 side, thereby restricting the expansion of the heating foam material. Further, a position restricting member may be disposed at an intermediate portion between the corner portions 36 and 37 on both sides of the reinforcing panel 30 and the connecting surface portions 41 and 41 on both sides to restrict the expansion of the heating foam material.

  An upper door hinge (not shown) for attaching a rear door (not shown) to the center pillar 2 is attached to the center pillar 2 via the outer panel 11 at the center in the vertical direction of the outer surface portion 31 of the reinforcing panel 30 of the center pillar 2. A portion 42 is formed. The upper hinge mounting portion 42 includes a mounting surface portion 43 that extends in the longitudinal direction of the vehicle body, an inclined portion 44 that extends upward from the upper end of the mounting surface portion 43, and upper hinge mounting holes 45 and 45 to which bolts and nuts (not shown) are mounted. And is formed in a bulging shape that bulges to the outer panel 11 side.

  As shown in FIG. 1, the protruding portion 39 is provided above the upper hinge mounting portion 42 and is formed so that the lower end thereof is continuous with the inclined portion 44 of the upper hinge mounting portion 42 as shown in FIG. 2. ing. That is, as shown in FIG. 4, since the inclined portion 44 and the protruding portion 39 are formed continuously, the change in the length in the vehicle width direction from the upper hinge mounting portion 42 of the reinforcing panel 30 to the upper side thereof. Has become moderate. Here, the reinforcing panel 30 is obtained by press-forming a metal plate material such as a steel plate into a substantially hat-shaped cross section. In this case, the press molding process direction is from the vehicle inner side to the vehicle outer side of the reinforcing panel 30, but if the change in the length of the reinforcing panel 30 in the vehicle width direction is gentle, the change in the drawing depth becomes gentle. Therefore, it becomes difficult to produce molding defects such as wrinkling during press molding.

  As shown in FIG. 2, the filling members 50 and 51 on both sides are provided on both the front and rear sides of the protrusion 39, but it is not necessary to provide the entire length in the longitudinal direction of the protrusion 39, depending on the shape of the center pillar 2 and the like. Thus, it may be provided only at a site where an improvement in bending strength is particularly required.

  Next, the operation at the time of a vehicle side collision will be described. When a collision load is applied to the outer panel 10 of the center pillar 2 from the outside in the vehicle width direction due to a side collision of the vehicle, the outer panel 10 applies the initial load at the initial stage of the collision to the vertical surface portions on both sides of the filling members 50 and 51 on both sides and the reinforcing panel 30. This is transmitted to the inner panel 20 via 32 and 33. At this time, in most of the longitudinal direction of the reinforcing panel 30, as shown in FIG. 8 (comparative example), when the filling members 50 and 51 on both sides are in contact with the protruding portion 39, the initial load is applied to the filling members on both sides. 50, 51 is also transmitted to the projecting portion 39, the projecting portion 39 is crushed, and the corner portion formed by the projecting surface portion 40 and the connecting surface portions 41, 41 on both sides becomes substantially flat, thereby improving the bending strength. Is not obtained, and the bending strength of the center pillar 2 is lowered. In this case, it is necessary to take measures to increase the weight of the vehicle body such as increasing the thickness of the reinforcing panel 30, which is disadvantageous from the viewpoint of weight reduction.

  In contrast, in the present embodiment, the initial load is transmitted to the inner panel 20 through the filling members 50 and 51 on both sides and the vertical surface portions 32 and 33 on both sides of the reinforcing panel 30, Not transmitted. Then, at the next stage in the initial stage of the collision, the outer panel 10 is deformed toward the reinforcing panel 30, the outer panel 10 comes into contact with the protruding portion 39 of the reinforcing panel 30, and the load is transmitted from the outer panel 10 to the protruding portion 39 of the reinforcing panel 30. Is done. At this stage, since the initial load is after being transmitted to the inner panel 20, the load transmitted from the outer panel 10 to the projecting portion 39 is reduced and formed by the projecting surface portion 40 and the connecting surface portions 41 and 41 on both sides. The shape of the corners is maintained, and an effect of improving the bending strength is obtained. That is, in this embodiment, the load is transmitted to the protruding portion 39 of the reinforcing panel 30 after a predetermined time has elapsed from the beginning of the collision, so that the shape of the protruding portion 39 can be maintained and the original bending strength improvement effect can be obtained.

  Since the load from the rear door is directly input to the upper hinge mounting portion 42 at the time of a vehicle side collision, the upper portion is a portion where the load is particularly concentrated in the center pillar 2, but a protrusion 39 is provided at the portion. Thus, the bending strength can be further effectively improved. And since the protrusion direction of the protrusion part 39 is the same direction as the bulging direction of a door hinge attaching part, the change of the aperture depth of the reinforcement panel 30 above the upper hinge attaching part 42 can be made moderate, and it shape | molds Defects can be made difficult to occur. Further, since the protrusion 39 of the reinforcing panel 30 is formed continuously with the upper hinge mounting portion 42, no step or the like is formed between the protrusion 39 and the upper hinge mounting portion 42. Therefore, the load input from the rear door Therefore, the load can be reliably received without taking measures such as increasing the thickness of the reinforcing panel 30, that is, while having a lightweight structure.

  FIG. 5 is an explanatory diagram for explaining a simulation for analyzing the bending deformation behavior of the center pillar, and is a diagram illustrating a model used for analyzing the bending deformation behavior of the center pillar.

  Specifically, as shown in FIG. 5, the lower surface portion 200b of the center pillar 200 having a predetermined length X1 is supported by two fixed points 201 separated by a predetermined distance X2 shorter than the length X1. The indenter 202 is lowered from above at a central portion P1 in the longitudinal direction of the upper surface portion 200a of the center pillar 200 corresponding to an intermediate position between the two fixed points 201 from above, and is acted from the outside via the indenter 202 at the time of a vehicle collision. A load F simulating the load to be applied was added to the center pillar 200, and the bending deformation behavior of the center pillar was examined. When the load F is added, the maximum load that can be applied before the center pillar 200 is bent is calculated, and this maximum load is used as a guideline for evaluating the superiority or inferiority of the bending strength characteristics.

  As shown in FIG. 3, the distance between the outer surface portion 31 of the reinforcing panel 30 and the inner wall 11a of the outer surface portion 11 of the outer panel 10 is L, and the height of the protruding portion 30 from the basic surface portion 38 of the outer surface portion 31 is H. The above-mentioned bending test was performed on the center pillar 200 with the value of changed, and the bending strength improvement rate was calculated based on the case where the reinforcing panel 30 did not have the protrusion 39 (when H = 0). As a result, as shown in FIG. 6, it was found that H / L preferably satisfies 0.5 or more. That is, when the protrusion 39 is not present (H / L = 0) and the protrusion 39 is present (H / L is greater than 0), the bending strength is improved, but H / L is 0.5 or more. By satisfying the above, since the bending strength improvement rate is greatly improved, the bending strength of the center pillar 2 can be further improved.

  Here, the distance (LH) between the protruding portion 39 and the outer panel 10 needs to be secured from the viewpoint of productivity and the occurrence of abnormal noise due to contact between the two during normal running. Therefore, the upper limit of H / L is less than 1.0. The predetermined interval varies depending on the shape and size of the center pillar 2, but the distance L between the basic surface portion 38 of the outer surface portion 31 of the reinforcing panel 30 and the inner wall 11a of the outer surface portion 11 of the outer panel 10 is about 5 to 10 mm. In some cases, the predetermined spacing is on the order of 1-2 mm. Therefore, it is preferable that the height H of the projecting portion 39 be as high as possible within the range in which the productivity can be maintained and abnormal noise can be suppressed.
