Description

Side frame and cowl-dash panel joint structure of automobile

The present invention relates to a side frame and a cowl-dash panel joint structure of an automobile, and more particularly to a structure in which a cowl-dash panel is bonded to a front pillar portion adjacent to the bonnet and the front fender of the side frame. It is about.

In general, the side frame of an automobile refers to a side frame structure of a vehicle, as the name implies, so that the front and rear doors are rotatably provided. That is, the center pillar is connected to the front pillar of the side frame of the windshield glass and the front pillar to the side frame, the roof rail of the side structure of the roof panel, and the center pillar connected to the middle of the roof rail below to form the structure between the front and rear doors. A quarter panel, which is connected to the rear end of the roof rail and the quarter glass is installed, and a side seal panel that horizontally connects the lower part of the quarter panel and the lower end of each pillar to be installed by welding.

Therefore, the front pillar part 1 of the side frame in which the front pillar was installed is arrange | positioned adjacent to the front fender 2 provided in the front wheel, as shown in FIG. 1, and this front fender 2 Is arranged adjacent to the side of the bonnet 3 rotatably installed in the upper part of the engine room.

Meanwhile, as shown in FIG. 2, the front cowl panel 4 is welded to the front end of the front pillar part 1 of the side frame, and each front pillar part 1 is connected to the cowl-dash panel 5. It is supposed to be. That is, both sides of the cowl-dash panel 5 are superposed on the front end of the front pillar portion 1 and the side cowl panel 4 and fixed by welding.

However, in the conventional joining structure, since the welding surface of the cowl-dash panel 5 is formed only when the side frame is first bonded to the side pillar panel 4, the side cowl panel 4 has a side surface. The front pillar portion 1 of the frame was welded and then the cowl dash panel 5 was welded to the front pillar portion 1 and the side cowl panel 4.

By the way, since the front pillar part 1 and the side cowl panel 4 part to which the side cowl panel 5 is welded are narrow spaces of a triangular shape, there existed a problem that welding operation was very difficult.

In addition, the conventional joint structure has a fundamental problem that the welding area between the cowl-dash panel 5 and the front pillar portion 1 is absolutely narrow, and thus the strength is weak.

In particular, according to the conventional joining structure, as shown in FIG. 1, the front pillar portion 1 of the side frame is adjacent to and disposed only at the front fender 2, and is not adjacent to the bonnet 2. However, the above-described triangular narrow spaces should be naturally formed, and thus many pointed out that the appearance is not beautiful.

Therefore, the present invention has been devised to solve the problems caused by the conventional joining structure, it is possible to finally join the pillar portion of the side frame, the side frame and the cowl of the automobile which can facilitate the welding work easier The purpose is to provide a dash panel joining structure.

In addition, the present invention has another object to provide a side frame and a cowl-dash panel joining structure of the vehicle that can increase the strength by increasing the welding area between the side frame and the cowl-dash panel as possible.

In addition, the present invention allows the front pillar of the side frame to be disposed adjacent to not only the front fender but also to the bonnet, so that a narrow triangular space that makes welding work difficult is not formed, and also improves the appearance. Another object is to provide a side frame and cowl-dash panel joint structure.

Explanation of symbols on the main parts of the drawings

1: Front pillar part of side frame 2: Front fender

3: bonnet 5: cowl-dash panel

6: fixed part 7: wheel apron reinforcement

61: first flange 62: second flange

63: 3rd flange

In order to achieve the above object, the present invention, the front of the front pillar portion of the side frame constituting the side frame of the vehicle body, the fixing portion of the triangular cross-sectional shape disposed adjacent to each of the front fender and the bonnet is extended, formed, the fixing portion Three flanges are formed at the bottom of each side of the surface, two of which are overlapped and welded on the front pillars of the side frame and the wheel apron reinforcement, and the cowl-dash panel is overlapped and welded to the remaining flanges. It is characterized by.

According to the above-described configuration of the present invention, a triangular space formed by the front pillar portion, the front fender, and the bonnet of the side frame is shielded by the fixing portion, and the fixing portion is fixed to the cowl-dash panel, thereby making it a narrow space. This eliminates the need for welding, and facilitates welding work, and welding is performed along each flange of the fixing portion, thereby greatly increasing the welding area and enhancing rigidity.

EXAMPLE

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

3 is a perspective view showing an arrangement relationship between the front pillar portion of the side frame and the front fender and the bonnet by the bonding structure according to the present invention, Figure 4 is an exploded perspective view showing a bonding structure according to the present invention.

For reference, in the description of the configuration of the present embodiment, the same parts as in the prior art described at the beginning of the specification are omitted and repeated descriptions are mainly described in order to avoid duplication of description. use.

As shown in Fig. 3, the front pillar portion 1 of the side frame is, unlike the prior art, the front end of which is disposed adjacent to the front fender 2 and the bonnet 3. The reason why such an arrangement is possible is that the fixed portion 6 having a triangular cross-sectional shape is extended and formed at the front end of the front pillar portion 1, and the fixed portion 6 is formed of the front pillar portion 1 and the front fender ( It is because it is interposed in the triangular-shaped space part formed between 2) and the bonnet 3.

That is, as shown in Figure 4, the fixing part 6 is proposed in the present invention is a volume having a triangular cross section, three first, second, and third flanges 61, 62 at the bottom of each surface , 63). The first flange 61 is welded to the front pillar portion 1, the second flange 62 is welded onto the reinforcement member 7 of the wheel apron supporting the front wheels, and the cowl to the remaining third flange 63. The dash panel 5 is welded.

It is constructed as described above, the first flange 61 is welded to the front pillar portion 7 and the second flange 62 is welded to the wheel apron reinforcement 7 and then cowl-dashed to the third flange 63. The panel 5 may be welded. Therefore, the welding work of the cowl-dash panel 5 is not carried out in a narrow space, but is carried out on the flange 63 of the fixing part 6 exposed upward, making welding work easier.

In addition, by performing along the entire flanges 61, 62, and 63 of the fixing part 6, the welding area is greatly increased compared with the conventional one, and the front pillar part 1 of the side frame is stiffened.

As described above, according to the present invention, the welding operation of the cowl-dash panel 5 does not have to be carried out in a narrow space, which facilitates the welding operation.

In addition, since welding is performed along the entire flanges 61, 62, 63 of the fixing part 6, the rigidity of the front pillar part 1 is greatly enhanced by the increase in the welding area.

In addition, the front end of the front pillar part 1 is disposed adjacent to not only the front fender 2 but also the bonnet 3, and as a result, the front fender 2 is straightened without a curved surface, so that the appearance is more beautiful. Become.

On the other hand, the present invention is not limited to the above-described specific preferred embodiments, anyone of ordinary skill in the art to which the present invention pertains without departing from the gist of the present invention claimed in the claims may be variously modified. will be.
