Description

Cowl panel reinforcement structure of automobile body

The present invention relates to a reinforcement structure of a cowl panel of an automobile body, and in particular, by installing a reinforcing member between the cowl panel and the handle column mounting bracket, the vehicle body can be connected to the cross member and improve the support rigidity of the handle column. Of cowl panel reinforcement structure.

In the framed vehicle, the front body is formed of an engine compartment. As shown in FIG. 1, the front body of the vehicle is configured to distinguish the engine compartment from the interior of the vehicle while forming the engine compartment E. As shown in FIG.

That is, the front end panel 1 is installed at the front side of the engine compartment E, and the side walls of the engine compartment E are coupled to both sides of the front end panel 1 to support various components arranged in the engine compartment. A fender shield (2) is installed to withstand the load transmitted from the body mounting, and a dash panel (3) is installed at the rear of the engine compartment to distinguish it from the cabin.

And the dash panel (3) serves to prevent the noise and vibration of the engine compartment is transmitted to the interior, the cowl panel 10 is coupled to the upper portion, the front pillar (5) in the vertical direction at the side end Is combined.

In particular, the cowl panel 10 is vertically coupled to the cowl top panel 11 and the cowl bottom panel 12 so that the inside of the cowl panel 10 has a box-shaped closed end surface, and the front pillar 5 and the left and right ends thereof are formed at the right and left ends thereof. It is welded and fixed to the dash panel 3.

However, as described above, the cowl panel coupled to each other is provided with a column mounting bracket and a cross member for supporting the column of the steering wheel at the lower side thereof, but since there is no connection structure, there is sufficient rigidity against torsional torsional load. Problems that do not have occurred.

The present invention has been made in order to solve the above problems, by connecting the cowl panel and the column mounting bracket with a reinforcing member to reinforce the cowl panel reinforcement structure of the vehicle body to improve the rigidity against torsional load generated in the front and rear direction To provide.

The cowl panel reinforcement structure of the vehicle body of the present invention for realizing the above object is a pair of cowl top panel and cowl lower panel which is located on the upper side of the engine compartment and the compartment is separated; A column mounting bracket positioned at a lower front of the pair of cowl panels and having a cross member passing thereon and a column of a steering handle mounted thereon; A reinforcing member installed between the cowl lower panel and the column mounting bracket to reinforce rigidity; It is possible to be characterized by consisting of.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

Figure 2 is a schematic configuration diagram showing a cowl panel reinforcement structure of the vehicle body according to the present invention, Figure 3 is a coupling diagram of the A-A line of FIG.

As shown in Figs. 2 to 3, the present invention is located on the upper side of the dash panel (not shown) in which the engine compartment and the cabin are separated, and at the same time, a cowl composed of a cowl upper panel 51 and a cowl lower panel 52. A panel 50, a column mounting bracket 60 positioned below the cowl panel 50 and mounted with a column of a steering wheel, and installed in the longitudinal direction of the cowl panel 50 for the column mounting. The cross member 70 which passes to the upper side of the bracket 60, and the reinforcing members 81 and 85 which are installed between the said cowl lower panel 52 and the said column mounting bracket 60, and reinforces rigidity are comprised. .

Here, the reinforcing members 81 and 85 are formed of a first bracket 81 and a second bracket 85 which are fixed to each other in contact with each other. The first bracket 81 has a bottom surface of the cowl lower panel 52. Both ends 81a are bent and fixed to each other.

In addition, the second bracket 85 is formed in a 'c' shape so that one end portion 85a is fixed to the bottom surface of the first bracket 81 and the other end portion 85b is fixed to the column mounting bracket 60. The bottom of the bolt is fastened with a bolt 88 and a nut 89 is fixed.

Referring to the operation of the cowl panel reinforcement structure of the vehicle body according to the present invention configured as described above are as follows.

The cowl panel and the column mounting bracket are spaced up and down a certain distance, and the first and second brackets are installed between them, so that each torsional load generated in the cowl panel and the column mounting bracket can be mutually supported. Will be.

Here, the first bracket is bent almost similarly to the bottom surface of the cowl lower panel, and the second bracket is fixed as if it is erected in a vertical direction between the first bracket and the column mounting bracket so that the load in the vertical direction is increased. It is possible to easily support and reinforce the support strength of the column mounting bracket.

In addition, since the first bracket and the second bracket are assembled to the column mounting bracket by bolts and nuts in a state of being fixed to the cowl panel side by welding or the like, the assembly structure is also easy.

On the other hand, the column mounting bracket is fixed to the lower side of the cross member is eventually connected to the cowl panel is to be reinforced the rigidity against the torsional load as a whole.

Therefore, the cowl panel reinforcement structure of the vehicle body of the present invention constructed and operated as described above has rigidity against torsional load generated in the front and rear direction of the cowl panel because the cowl panel and the column mounting bracket are interconnected through the reinforcing member. The improved rigidity and the supporting rigidity of the column mounting bracket are also provided.
