[Industrial use]

The present invention relates to a bottom reinforcement dashboard of a vehicle, and in particular, a separate auxiliary blocking panel is mounted on the dash lower panel of the dashboard that divides the engine room and the passenger compartment to block noise / vibration transmitted from the engine, The present invention relates to a bottom reinforcement dashboard of a vehicle capable of improving rigidity of an external force applied in a crash accident and improving the damage deformation of the vehicle body and the safety of passengers.

[Prior art]

In general, a dash board used in a vehicle is a partition plate that divides the engine room and the passenger compartment of the front body of the vehicle, and includes noise / vibration, dust, and sewage into the passenger compartment. It is a plate that blocks the inflow of machinery.

The dashboard consists of a front floor panel, a dash lower panel connected to each other, and a dash upper panel positioned at an upper end of the dash lower panel and fixed to each other.

Referring to FIGS. 1 and 2, a conventional dashboard connected to the front floor panel as described above is briefly described as follows.

Conventional dashboard is a front floor panel (1) and the upper / lower end (2a, 2b) is formed at the bottom of the passenger compartment of the vehicle and the front seat is mounted on the upper surface is bent at right angles to each other and the lower end (2b) Is connected to the lower end of the front floor panel (1), the dash lower panel (2) is fixed to the top and the cowl panel (3A) is bent in a multi-step bent stair shape is fixed to the top and the lower lower panel ( It consists of a dash upper panel (3) fixed to it.

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 that is located between the engine room and the boarding room so that the vibration and noise blocking function is blocked to prevent the transmission of vibration / noise, etc. into the boarding room, and the front / side collision accident Insufficient stiffness to respond to external force applied to the vehicle, preventing deformation of the vehicle body, engines and various mechanical devices, etc. 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 for reinforcing the bottom of the vehicle that can improve the plate damage deformation and the safety of the passengers by blocking the back and securing the rigidity against external force applied in the front / side collision accident.

[Configuration and Action of Design]

In order to achieve the above object, the present invention is a front floor panel constituting the bottom surface of the vehicle compartment of the vehicle, the middle portion is bent at a predetermined inclination angle to form an inclined surface and the upper / lower end is bent into a channel shape (c) and the inclined surface It provides a dashboard of the vehicle, characterized in that consisting of a dash lower panel is formed, the cover is attached to the fixed reinforcement panel, and the dash upper panel fixed to the cowl panel and interconnected.

Here, the reinforcement panel flange portion of the channel shape (c) is attached to the outer surface of the inclination surface of the dash lower panel to form a closed space.

In the present invention as described above, by installing a separate reinforcement panel on the dash lower panel of the dashboard to block the noise / vibration transmitted from the engine to improve the ride comfort and secure the corresponding rigidity to the external force applied in the front / side collision accident Therefore, it is possible to improve the merchandise and reliability of the product by suppressing breakage deformation of the vehicle body and increasing passenger safety.

EXAMPLE

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

3 is a perspective view showing a bottom reinforcement structure provided on a dashboard of a vehicle according to a preferred embodiment of the present invention, and FIG. 4 shows a bottom reinforcement structure on a dashboard of the vehicle according to the present invention. It is sectional drawing of the bb line of FIG. 3, (b) is a schematic side cross-sectional view in C direction shown in FIG.

In this way, the present invention forms a floor of the passenger compartment of the vehicle, and the front floor panel 10 on which the front seat is mounted on the upper surface, and the middle part is bent at a predetermined inclination angle to form the inclined surface 21 and have a channel shape (c). Dash lower panel 20 that forms a flange portion 24a of the lower end, and has a reinforcement panel 24 that fixes and attaches the inclined surface 21 to be covered, and a dash upper panel 30 fixedly connected to the cowl panel 31. It consists of).

The reinforcement panel 24 is bent into a channel shape (C) and the flange portion 24a formed at both ends is fixed to the upper and lower outer sides of the inclined surface 21 of the dash upper panel 20 so that the closed space 25 is fixed. Is formed.

On the other hand, the closed space 25 generated by the combination of the reinforcement panel 24 and the dash lower panel 20 ensures the corresponding rigidity to the external force applied during the side impact.

First of the present invention having the configuration as described above, the lower end of the cowl panel 31 formed in multiple steps bent in a step shape is fixed to the upper end of the dash upper panel 30.

In addition, the inclined surface 21 bent at a predetermined inclination angle in the middle portion of the dash lower panel 20 is attached to one surface of the middle portion of the upper portion 22 so that the outer surface is covered with the lower portion 23 to the dash lower panel 20. It is attached and fixed between the upper end of the lower end and the lower end of the front floor panel (10).

Therefore, the present invention, as shown in FIGS. 3 and 4, the one end flange portion 25 of the reinforcement panel 24 of the channel shape (c) is attached and fixed to one inner surface of the front side frame 27, respectively. The other side end flange portion 25 of the reinforcement panel 24 is secured to the outer surface of the inclined surface 21 of the dash lower panel 20 so that noise, vibration dust, etc. are carried on. Inflow into the room can be blocked in two stages.

[Effect of design]

As described above, according to the present invention, a separate reinforcement panel is mounted on the dash lower panel of the dashboard to block noise and vibration distribution transmitted from the engine, thereby improving riding comfort and responding to external force applied during a front / side collision.
