Description

Center pillar reinforcement structure of convertible vehicle

The present invention relates to a center pillar of a convertible vehicle, and more particularly, to a convertible that can protect passengers by attaching a reinforcement panel to the center pillar of the convertible vehicle to prevent an impact from entering the vehicle during a side collision accident. A center pillar reinforcement structure of a vehicle.

Cars are categorized by their appearance, which can be divided into passenger cars with a small number of passengers, buses that can carry large numbers of passengers, trucks used to carry cargo, and trailers that carry large equipment or containers. have.

Here, the passenger car can be classified in various ways depending on the appearance. The sedan is a typical notchback style vehicle with two to four doors. A limousine is a luxury car for VIPs that is bigger than a sedan in shape but has a glass partition between the driver's seat and the rear seat. In addition, the convertible vehicle is configured so that the roof is not iron plate, and the cover made of cloth or vinyl is manually or automatically folded on and out of the frame, and in a sports car, a two-seater vehicle without a side window is also called a road star. .

1 is a rear perspective view showing the configuration of a typical convertible vehicle. In view of the overall configuration thereof, the door 2 is mounted on the side of the two-seater convertible vehicle so as to be openable and close, and the wind seed 4 is provided at the front to prevent the wind blowing from the front during driving. In addition, the back of the seat 8 is provided with a cover 6, which can be deployed manually or automatically, so that when it rains or does not snow, the cover 6 is moved in a walking state as shown, thereby providing fresh air. Can keep the pleasant environment.

2 is a perspective view showing the configuration of a conventional center pillar. The center pillar 10 is disposed on the side of the convertible vehicle, and the rear wheel house and the side member lower reinforcing plate 12 connecting the center pillar are welded to the lower end of the center pillar 10. In addition, a rear floor cross member 14 is disposed above the floor panel 18 to prevent the floor panel 18 from being deformed by an impact flowing in the lateral direction through the center pillar 10. The side floor panel 16 is vertically attached to the side of the floor panel 18 to provide a side sill on which the door is seated. Unexplained reference numeral 20 denotes a welded portion.

Since the conventional convertible vehicle having such a configuration has no loop, the lower end of the center pillar is bent by an impact transmitted from the outside in the event of a side collision, and the entire center pillar falls to the inside of the vehicle, causing a fatal injury to the passenger.

The present invention devised to solve this problem is to attach a reinforcement panel connecting the rear floor cross member, the center pillar and the side floor panel to protect the passengers by preventing the center pillar from falling toward the interior during side impact. The object is to provide a center pillar reinforcement structure for a convertible vehicle.

The object of the present invention described above is a center pillar disposed on the side of the vehicle, a side member lower reinforcing plate connecting the center pillar and the rear wheel house, a rear floor cross member fixed to the floor panel, and a side of the floor panel. A convertible vehicle having a side floor panel vertically installed in a vehicle, comprising: an upper fixed end attached to the rear floor crossmember and a center pillar, a lower fixed end attached to the floor panel and the side floor panel, and an upper fixed end and a lower fixed end. It is achieved by the center pillar reinforcement structure of the convertible vehicle, characterized in that it comprises a reinforcement panel made of a connecting portion disposed in.

Hereinafter, the center pillar reinforcing structure of the convertible vehicle according to the preferred embodiment of the present invention will be described with reference to the accompanying FIGS. 3 and 4. do.)

3 is a perspective view showing the configuration of the center pillar is attached to the reinforcing panel according to the present invention, Figure 4 is a perspective view showing the configuration of the reinforcing panel employed in the present invention.

First, as shown in Figure 3, in the preferred embodiment of the present invention as a way to increase the rigidity of the center pillar, the rear floor cross member 14, the center pillar 10 and the side floor panel 16 The reinforcement panel 30 was connected and fixed. The reinforcement panel 30 is comprised of three parts.

Among these, the upper fixing end 34 is fixed to the center pillar 10 and the rear floor cross member 14, and the lower fixing end 38 is fixed to the floor panel 18 and the side floor panel 16, The upper fixed end 34 and the lower fixed end 38 are coupled by a connection 36.

One side 34a of the upper fixing end 34 constituting the upper part of the reinforcing panel 30 is fixed to the center pillar 10, and the other side 34b is fixed to the rear floor cross member 14. To this end, the upper fixing end 34 was formed to be slightly inclined. In addition, the intermediate connecting portion is arranged on the vertical surface of the rear floor cross member 14. One side 38a of the lower fixing end 38 constituting the lower part of the reinforcement panel 30 is fixed to the side floor panel 16, and the other side 38b is fixed to the floor panel 18. For this purpose, the lower fixed end 38 is formed to be slightly inclined.

In addition, in the preferred embodiment of the present invention, in order to increase the strength of the reinforcing panel 30, the bead 32 is formed on the upper fixing end 34. As such, by forming the beads 32 in the upper fixing end 34, it is possible to prevent the reinforcement panel 30 is deformed by the impact introduced from the outside through the center pillar 10.

4 is a perspective view showing the configuration of the reinforcement panel 30 employed in the present invention. As shown here, the upper fixing end 34 and the lower fixing end 38 are integrally coupled by a connecting portion 36, and the upper fixing end 34 has beads 32 for increasing rigidity. It is. One side of the upper fixing end 34 is coupled to the connecting portion 36, the other side is formed with a curved end 39 is fixed to the rear of the rear floor cross member (14). The curved end 39 is disposed opposite the connecting portion 36.

According to the present invention described above, since the reinforcement panel connecting the rear floor cross member, the center pillar, and the side floor panel is provided at the lower end of the center pillar, the reinforcement panel is used even when a strong impact is transmitted from the outside during a side collision accident. By blocking the inflow to the indoor side, there is an advantage that can protect the occupants safely.
