Description

  The present invention relates to a side body structure of a vehicle in which a hinge reinforcement for reinforcing a door hinge mounting portion is provided in the vicinity of a joint portion between a side sill front portion and a hinge pillar lower portion.

  When a frontal collision or the like occurs in the vehicle, a large impact load acts from the front, the tire constituting the front wheel moves backward, and the tire abuts against the rear body member, so that the impact load is passed through the tire. May act on the vehicle body side.

  Therefore, conventionally, when the tire is retracted due to a frontal collision or the like and contacts the vehicle body, an impact load is transmitted along a side sill disposed at a height position substantially corresponding to the tire contact position. Measures are taken.

  The side sill is a member extending in the front-rear direction at the lower part of the both ends in the width direction of the vehicle body. By transmitting the impact load to the side sill as described above, the impact load is efficiently transmitted to the rear part of the vehicle body along the side sill. As a result, it is possible to suppress deformation of the passenger compartment.

  However, in recent years, there is a tendency that the diameter of the tire increases as the diameter of the wheel increases. In some cases, the impact load cannot be transmitted to the side sill by shifting the position transmitted to the side sill upward.

  Therefore, in order to solve such a problem, for example, as disclosed in Patent Document 1 below, in a hinge pillar to which a door hinge for a front door is attached, attachment of a lower hinge located in the vicinity of the side sill front and above It is conceivable to provide reinforcement in the part.

In this case, even if a tire having a large diameter is employed, the impact load can be reliably received by the reinforcement when the tire comes into contact with the vehicle body member in the event of a frontal collision of the vehicle. It is possible to suppress the cross-sectional deformation of the hinge pillar and the deformation of the passenger compartment caused by the above.

The side sill reinforcement 8b is disposed so as to be placed on the upper surface.

  A plurality of flange portions 14b, 14c, 114d are formed on the downwardly extending portion 14a of the hinge reinforcement 14, and these are joined to the side sill reinforcement 8b at the positions indicated by x in the figure. .

  In the present embodiment, the upper portion of the rear wall 114g of the hinge reinforcement 14 is close to the outer panel portion 10b and the rear walls 10f and 52b of the hinge pillar reinforcement 5b, and is moved forward in the middle. A flange portion 114d that bends and extends toward the front of the vehicle body extends from the lower end.

  In this case, the flange portion 114d extends forward of the vehicle body on the opposite side in the longitudinal direction of the vehicle body from the side where the rear walls 10f and 52b are disposed, so that welding is performed regardless of the presence of the rear walls 10f and 52b. The gun can be easily accessed from the inside in the vehicle width direction.

  That is, in the case of the present embodiment, after the hinge reinforcement 14 is fastened to the outer panel portion 10b in advance, the flange portion 114d of the hinge reinforcement 14 can be spot welded to the upper surface of the side sill reinforcement 8b. The hinge reinforcement 14 and the side sill reinforcement 8b can be joined after ensuring the positional accuracy of the hinge reinforcement 14 with respect to the outer panel portion 10b and the like.

  Even in the case of this embodiment, when the tire 7 moves backward due to a frontal collision of the vehicle and the tire 7 comes into contact with the rear wheel house 6 (see FIG. 1), the hinge reinforcement 14 extends downward. By joining the portion 14a to the side sill reinforcement 8b, as shown by thick arrows α ′, β, γ in FIGS. 9 and 10, the impact load is applied to the rear side of the vehicle body along the side sill reinforcement 8b.
