The present invention relates to a center pillar structure of a vehicle in which a reinforcing member is installed inside the center pillar for the purpose of protecting the occupant from an impact during a side collision of the vehicle, thereby significantly reducing the inflow of the interior of the center pillar.

In general, the stress is concentrated in the center pillar when the side of the vehicle crashes, which causes severe deformation, which causes a large amount of inflow of the center pillar. It can be seen that.

In FIG. 2 of the accompanying drawings, a center pillar structure in which the inner and outer panels 10 and 20 are sealed is formed and is simply combined. This existing center pillar structure has been very vulnerable to lateral impact, and thus, there is an urgent need for reinforcement of this area. Here, reference numerals 30 and 40 denote front and rear doors, respectively.

Therefore, the present invention has been devised in view of such a point, and a reinforcing member having a plurality of plate-shaped combinations is provided between the inner and outer panels of the center pillar, and most of the impacts at the time of collision are made by using its own supporting rigidity. It is an object of the present invention to provide a center pillar structure of an automobile that can be absorbed, thereby making it possible to minimize the inflow of the center pillar to the maximum.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention has a center pillar structure including the inner and outer panels 10, 20 combined to have a space to be sealed, the reinforcement panel 50 is installed in the center pillar, but The reinforcement panel 50 is a main reinforcement panel 50a and the inner panel 10 which are disposed to cross the center pillar while both ends are joined together and fixed between the inner and outer panels 10 and 20 at both ends of the joints. Each end is fused and fixed to the inner surface of the c) and each other end is bent into a concave groove shape, and at the same time, it overlaps at the center of the inner panel 10 to form a box-shaped space 51 together with the panel 10. It is characterized by consisting of two auxiliary reinforcement panel 50b disposed inward of the reinforcement panel 50a.

In particular, the middle portion of the width of the main reinforcement panel (50a) is characterized by consisting of the mountain-shaped bent portion 52 of the symmetrical form protruding outward.

This will be described in more detail as follows.

3 is a cross-sectional view showing a center pillar structure of the present invention.

Here, reference numeral 20 denotes a center pillar outer panel adjacent to the front and rear doors 30 and 40 on the outer side, and 10 denotes a center pillar inner panel which is combined while forming the center pillar outer panel and the enclosed space. Indicates.

The reinforcement panel 50 of the present invention is installed inside the center pillar inner and outer panels 10 and 20 thus combined, thereby further strengthening the binding between the inner and outer panels 10 and 20, and thus the panel 10 ) And (20) to complement the self-supporting stiffness.

The reinforcement panel 50 includes a main reinforcement panel 50a crossing the inner space of the inner and outer panels 10 and 20 and an auxiliary reinforcement panel 50b disposed inwardly of the main reinforcement panel 50a. It is composed.

The main reinforcement panel 50a is a strip-shaped panel that is much longer than its width, and is vertically disposed over the entire length of the center pillar.

The middle section of the width of the panel 50a is bent and formed into left and right symmetrical shapes having respective peaks 53 on both sides with a flat portion 52 in the middle thereof, and the flat portion 52 at this time is The panel 50a is positioned at a predetermined distance from both ends of the panel 50a. That is, the flat portion 52 is located outward from both ends, and at the same time the apex of the peak 53 faces outward.

The main reinforcement panel 50a may be joined together between the joints between the inner and outer panels 10 and 20 by using both ends, and may be fixedly supported at the inner space center of the inner and outer panels 10 and 20. It is installed so as to be able to further increase the linkage between the inner and outer panels 10 and 20 while maintaining a constant self-stiffness by the bending cross-sectional structure of the middle portion of the panel.

In addition, the auxiliary reinforcement panel 50b is a strip-shaped panel similar to the main reinforcement panel 50a, and is composed of a combination of two panels bent and molded into the same shape.

In other words, the trapezoid has a wing section 54 which extends horizontally from one end to a basic cross section. Each panel of a shape is provided, and each panel is comprised by the form combined integrally, overlapping a basic cross section with each other.

The auxiliary reinforcement panel 50b faces the trapezoidal basic cross section outwardly and at the same time, while positioning the left and right positions so that it can be positioned directly inside the flat portion 52, the inner panel ( Auxiliary reinforcement panel 50b which is fused and fixed to the inner surface of 10) is formed together with the inner panel 10 to form one box-shaped space 51 which means a buffer space.

Such an auxiliary reinforcement panel 50b not only doubles the rigidity of the inner panel 10 but also absorbs the residual impact reduced primarily by the main reinforcement panel 50a through the space 51.

Therefore, when the lateral impact during the vehicle side collision is transmitted to the outer panel 20 of the center pillar, the outer panel 20 at this time complementary linkage between the inner panel 10 through the main reinforcement panel 50a By using the support rigidity of the structure, the impact can be firstly reduced, while the residual impact reduced primarily by using the buffer space portion 51 constituted by the auxiliary reinforcement panel 50b and the inner panel 10. Since most of them can be reduced, the degree of inflow of the center pillar can be significantly reduced.

As described above, the present invention installs a reinforcement panel capable of effectively absorbing shock inside the center pillar, thereby minimizing the inflow of the center pillar in the event of a vehicle side collision, thereby protecting the occupant's safety as much as possible. There is an advantage.
