Description

Front pillar reinforcement structure of vehicle

The present invention relates to a front pillar reinforcement structure of a vehicle, and more particularly, after a reinforcement panel is installed between an outer panel and an inner panel of a front pillar, a front pillar reinforcement structure of a vehicle in which urethane foam is filled to increase rigidity. It is about.

In general, a car is divided into a body and a chassis, and the car body is an outer part of the car, and the engine room and the engine room where the engine is installed and the engine room are installed. It can be divided into a trunk compartment that can be stored and transported. In addition, the chassis is a part of the vehicle excluding the vehicle body, the vehicle is equipped with a variety of equipment necessary for the engine or driving is enabled to drive the vehicle. In general, in the case of a passenger vehicle, since an integrated frame composed mainly of one body frame is mainly used, a structure of a general vehicle body frame will be described with reference to FIG. 1 attached for better understanding of the present invention.

1 is a perspective view schematically showing the structure of a general vehicle body, wherein the front body 2 constitutes an engine compartment in which an engine which is a power generation source is mounted, and the rear body has a trunk capable of storing maintenance tools or loading various items. Construct a thread. In addition, the central roof 6 provides an interior space for passengers to board. The rear pillars are mounted on the center pillar 8, which is called a B pillar, and the front pillar 10, called the A pillar, is mounted on the side body. It can come out.

FIG. 2 is a cross-sectional view taken along the line I-I of FIG. 1, and in the structure of the conventional front pillar, the outer panel 12 constituting the outer portion of the front pillar 10 and the inner constituting the inner portion are shown in FIG. It consists of a panel 14 and an intermediate reinforcement panel 16. Here, the filler 18 obtained by foaming urethane foam is filled between the inner panel 14 and the reinforcement panel 16.

In the front pillar reinforcement structure of the conventional vehicle having such a configuration, the reinforcement panel and the filler are installed for the purpose of protecting the head part when the occupant is popped out by the elastic force, and the vehicle collides with an external impact. In the case of colliding and rotating and colliding with another object secondarily, the front pillar itself is severely damaged, which may seriously injure passengers. In addition, there is a problem that running wind generated when driving through the front pillar flows into the interior of the vehicle to lower the quietness.

The present invention devised to solve such a problem is to install two reinforcement panels in the inner panel and the out panel constituting the front pillar, and then foamed urethane foam between the outer panel and the reinforcement panel to form the entire front panel. An object of the present invention is to provide a front pillar reinforcement structure of a vehicle having increased rigidity.

1 is a perspective view showing the configuration of a general vehicle body,

2 is a cross-sectional view taken along the line I-I in FIG. 1,

Figure 3 is a view similar to Figure 2, a cross-sectional view showing the structure of the front pillar according to the present invention.

[Explanation of symbols on the main parts of the drawings]

20: front pillar 22: out panel

24: inner panel 26, 30: first and second reinforced panels

28, 32: 1st, 2nd filler

An object of the present invention described above is composed of an outer panel constituting an outer portion and an inner panel constituting an inner portion, and in the front pillar of a vehicle in which the front door is rotatably mounted, the inner panel is interposed through a first filler. And a first reinforcement panel disposed to be spaced apart from each other at regular intervals, and a second reinforcement panel disposed to be spaced apart from the outer panel at regular intervals through a second filler. do.

According to the present invention, a first filler filled between the inner panel and the first reinforcing panel constituting the front panel can protect the occupant's head in the event of a collision, and the second filled between the out panel and the second reinforcing panel. The filler prevents deformation of the front panel itself during rotational collisions, thereby reducing the impact of secondary collisions.

Hereinafter, with reference to the accompanying Figure 3 will be described in detail with respect to the front pillar reinforcement structure of a vehicle according to a preferred embodiment of the present invention.

Figure 3 is a view similar to Figure 2, a cross-sectional view showing a reinforcing structure of the front pillar according to the present invention.

In view of the overall configuration, the outer panel 22 forming the outer portion of the front panel 20, the inner panel 24 forming the inner portion, and the inner panel 24 are spaced apart from the inner panel 24 at regular intervals. The first reinforcement panel 26 and the second reinforcement panel 30 are spaced apart from the out panel 22 at regular intervals.

Here, between the outer panel 22 and the first reinforcing panel 26 is filled with the first filler 28 made of foam molded urethane foam, and similarly between the inner panel 24 and the second reinforcing panel 30. The second filler 32 obtained by foam-forming the urethane foam is filled with it. Therefore, the overall strength of the front panel 20 is increased by the first reinforcing panel 26 and the second reinforcing panel 30, and the first filler 28 and the second filler 32 filled therebetween. It fully absorbs the shock transmitted from the outside.

According to the present invention described above, the first filler filled between the inner panel and the first reinforcing panel constituting the front panel can protect the occupant's head in the event of a collision, and between the out panel and the second reinforcing panel The filled second filler prevents the front panel itself from deforming during rotational collisions, thereby reducing the impact of secondary collisions and protecting passengers. In addition, there is an effect that can improve the quietness by blocking the resonance sound (共鳴 音) and the transmission sound flowing into the vehicle interior through the front pillar.

Claims (1)
