Abstract

The present invention relates to a dash structure of an engine room capable of improving the structural strength against collisions while improving the noise blocking ability by forming a dash structure that spatially partitions the engine room and the interior into a triple structure. The front and rear reinforcement plates 21, 22 formed with a space inside the front and rear surfaces of the dash panel 10 that spatially partitions the engine room and the interior to complement the structural strength against the front collision and the front and rear The foam member 40 is embedded in the reinforcing plates 21 and 22 to impart sound absorption and sound insulation to the room.

Description

Dash structure of engine room

The present invention relates to a dash structure of an engine room, and in detail, by forming a dash structure that spatially partitions the engine room and the room into a triple structure to improve the noise blocking ability and at the same time improve the structural strength against collisions. It's about the dash structure of the engine room.

In the prior art, a dash structure of an engine room has a dash panel 10 that spatially partitions an engine room and an interior as shown in FIG. 1, and an insulator 30 is provided in front and rear of the dash panel 10. It is installed to shield the vibration and heat of the engine room.

On the other hand, the front of the dash panel 10 forms a space portion and at the same time forms a structure formed by contacting the reinforcement plate 20 to allow the foam material 40 to be embedded in the space portion.

However, the dash structure of the engine room, which is configured as described above, is provided with the insulator 30 before and after the dash panel 10 in forming the dash structure, thereby reducing the workability and further strengthening the dash panel 10 in the dash panel 10. 20) is a single one, which implies a structural weakness that is insufficient to cope with the impact that is pushed to the interior side when the front of the body collides.

The present invention has been made in view of the above problems, and an object of the present invention is to form a dash structure that spatially partitions the engine room and the interior in a triple structure to improve the noise blocking ability and at the same time to increase the structural strength against collisions. It is to provide a dash structure of the engine room which can be improved.

In order to achieve the above object, the present invention is to contact the front and rear reinforcement plate formed with a space inside the front and rear surfaces of the dash panel that partitions the engine room and the interior to compensate for the structural strength against the front collision and the front and rear It is a basic feature to impart sound absorbing and sound insulating functions to a room by embedding a foam material inside the reinforcing plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Detailed description of the present invention with reference to the accompanying drawings as follows.

2 is a cross-sectional view showing a dash structure of the engine room according to the present invention, in which the engine room and the interior side are spatially partitioned by the dash panel 10.

The front and rear reinforcement plates 21 and 22 are fixed to the front and rear surfaces of the dash panel 10, and the front and rear reinforcement plates 21 and 22 are pushed into the engine room during the front collision of the vehicle body. Imparts structural strength to prevent lifting.

In the interior of the front and rear reinforcement plates 21 and 22, a space part is formed, and the foam material 40 is embedded therein.

At this time, the foam member 40 embedded in the front reinforcement plate 21 has a low foaming state to give a sound insulation effect for the engine noise, and the foam member 40 embedded in the rear reinforcement plate 22 has a high foaming state. By providing a sound absorbing effect, the noise of the engine generated during operation is shielded from being transmitted to the room.

Accordingly, the present invention provides a triple reinforcing structure by the dash panel 10 and the reinforcing plates 21 and 22 formed on the front and rear surfaces thereof, thereby providing sufficient structural strength against frontal collisions, and also providing the dash panel 10. By forming the foam 40 to the front and rear of the double to have a soundproof structure that can improve the sound absorption and sound insulation effect for the engine to create a comfortable indoor environment for passengers aboard.

As described above, the present invention is a useful invention that forms a dash structure that spatially partitions the engine room and the interior in a triple structure to improve the noise blocking ability and at the same time improve the structural strength against collision.

Claims (1)

The front and rear reinforcement plates with spaces inside the front and rear surfaces of the dash panel that partitions the engine room and the room are contacted to compensate for the structural strength against front collisions, and by embedding the foam inside the front and rear reinforcement plates. Dash structure of the engine room, characterized in that it provides sound absorption and sound insulation functions for the room.
