Dash lower panel (2) that is connected to the lower surface of the front end portion of (1) and the cowl panel (3A) is bent in a multi-stage bending step shape is fixed to the top and the bottom is attached to the dash lower panel (2) Consists of a dash upper panel (3).

The dash lower panel 2 is a single plate bent at a right angle so that the upper end (2a) in the horizontal state toward the front, the other end is extended vertically and bent at a predetermined angle in the middle portion to form an inclined surface (2c) again in a horizontal state It is formed by the lower end part 2b bent at right angles toward the rear side.

[Technical Challenges to be Done]

However, the dashboard of such a conventional vehicle has a dashboard located between the engine room and the passenger compartment to block the transmission of vibration / noise, etc. to the interior of the passenger compartment. Insufficient stiffness to respond to external force applied to prevent damage deformation of engine body and engine or various devices flow into the boarding room, which reduces the stability that can threaten the life of the passengers. There was.

Therefore, the present invention has been devised to solve the fundamental problems of the prior art, and its purpose is to install a separate auxiliary blocking panel on the dash lower panel of the dashboard that divides the engine room and the passenger compartment. It is to provide a dashboard of a vehicle with reinforcement and soundproof structure that can block the back and secure the stiffness of the external force applied in the front / side collision accident to improve the deformation of the car body and the stability of the passenger.

[Configuration and Action of Design]

In order to achieve the above object, the present invention is the front floor panel constituting the bottom surface of the vehicle compartment of the vehicle, and the middle portion is bent at a predetermined inclination angle to form an inclined surface and the upper and lower ends are bent at right angles in different directions, the inclined surface Provided is a dashboard of a vehicle having a reinforcement and soundproof structure, characterized in that consisting of a dash lower panel is formed, the cover is attached to a fixed secondary blocking panel, and the dash upper panel fixed to the cowl panel and interconnected.

Here, the auxiliary blocking panel is bent at a right angle so that the outer closing space is formed between the outer side of the inclination surface of the dash lower panel and the auxiliary blocking panel, and the upper and lower ends are attached and fixed, respectively.

In addition, the auxiliary blocking panel is bent at a right angle and the upper and lower ends are bent at right angles in different opposite directions, and an inner closed space is formed between the inner side of the inclined surface of the dash lower panel and the auxiliary blocking panel, so that the upper and lower ends are respectively inside. Attached to the side is fixed.

An inner / outer closed space formed between the auxiliary blocking panels to which the inner or outer surface of the inclined surface of the dash lower panel is covered and fixed is filled with a foamed dustproof / soundproof material that attenuates vibration and noise.

In the present invention as described above, by attaching a separate auxiliary blocking panel to the dash lower panel of the dashboard to block the noise / vibration transmitted from the engine to improve the ride comfort and the stiffness of the external force applied in the case of the front / side collision accident By securing the suppression of the deformation of the car body and increase the stability of the passenger can be improved the productability and reliability of the product.

EXAMPLE

Hereinafter, a preferred embodiment of the present invention as described above with reference to the accompanying drawings in more detail as follows.

Attached FIG. 3 is a side cross-sectional view of the dashboard of the vehicle according to a preferred embodiment of the present invention with a reinforcement and soundproof structure provided, and FIG. Figure 5 is a side cross-sectional view showing a state provided, Figure 5 (a) (b) shows another embodiment side cross-sectional view showing a state in which the vibration-proof and soundproof member is built in the dashboard of the present invention, respectively.

As can be seen from the above, the present invention forms the bottom surface of the passenger compartment of the vehicle and the front floor panel 10 on which the front seat is mounted, and the middle portion is bent at a predetermined inclination angle to form an inclined surface 21. The upper and lower ends 22 and 23 are bent at right angles in different opposite directions, and the dash lower panel 20 having the auxiliary blocking panel 24 fixed to the inclined surface 21 to be covered and the cowl panel 31 and It consists of a fixed dash upper panel 30 interconnected.

Here, the auxiliary blocking panel 24 is bent at a right angle, and the upper and lower ends are bent at right angles in different opposite directions, and an inner closed space is formed between the inside of the inclined surface 21 of the dash lower panel 20 and the auxiliary blocking panel 24. 24A is positioned so that the upper and lower ends are attached and fixed to the inner side, respectively.
