Description

  The present invention relates to a front structure of an automobile including a shroud disposed behind a bumper beam, and a seal plate that divides a side portion of the shroud and a bumper face into left and right sides.

  Conventionally, a front side frame (body frame) extending in the front-rear direction of the vehicle is provided on both left and right sides in the engine room, and a bumper beam extending in the vehicle width direction is provided so as to bridge between the pair of left and right front side frames. There is known a front structure of an automobile in which a shroud provided with a radiator holding portion for holding a radiator is disposed behind the bumper beam, and a side portion of the shroud is attached to a vehicle body on the side portion thereof. (See Patent Document 1).

  Since the above-mentioned shroud holds a radiator that air-cools engine cooling water (or coolant) as a heat exchanger with the traveling wind, there is a demand to appropriately introduce the traveling wind into the radiator. If there is a gap, the hot air in the engine room blows back through the gap and circulates to the front side of the radiator, and this hot air is undesirably supplied to the radiator, causing a problem that the heat exchange performance of the radiator is lowered. .

  Therefore, in order to solve such problems, as disclosed in Patent Document 2, a seal plate is provided on the side portion of the shroud to prevent the hot air in the engine room from blowing back and wrapping around the front side of the radiator. A front structure for a motor vehicle that has been designed is already invented.

  The above-described seal plate partitions the side portion of the shroud and the bumper face on the left and right sides, and a concave portion is formed in a portion corresponding to the bumper beam, and the side portion of the shroud is formed above and below the concave portion. It has a bulging shape that partitions the bumper face.

  By the way, the bumper rain including the crash can and the bumper beam is already attached to the vehicle body before the shroud is placed because the actual vehicle has the bumper rain attached to the vehicle body and the anticorrosion coating is applied. The shroud and the seal plate are assembled after mounting.

  Therefore, considering a structure in which the shroud and the seal plate are sub-assembled in advance, the shroud provided with the seal plate may be inserted between the bumper beam rear portion and the engine front portion from above, but between the bumper beam and the engine. Since there is no space necessary for inserting the shroud including the seal plate from above, assembly is impossible.

Also, without sub-assembling the shroud and the seal plate in advance, only the shroud is once inserted from above between the rear part of the bumper beam and the front part of the engine. When the seal plate is disposed between the bumper beam and the shroud, the seal plate is formed in a shape in which both upper and lower portions bulge from the concave portion at a position corresponding to the bumper beam. After that, there is a problem that the assemblability is extremely bad, such as it is necessary to move it in the horizontal direction, and when trying to improve this assemblability, it is assembled between the position immediately after the bumper beam and the seal plate. There is a problem that a gap for improving the sealing performance is required, and the sealing performance deteriorates due to this gap.
