Description

Door outer panel reinforcement structure

The present invention relates to a door outer panel reinforcement structure, and more particularly to a door outer panel reinforcement structure that prevents the door from being deformed by reinforcing the outer panel of the vehicle door, and increases the safety of the occupants by increasing the side impact strength of the vehicle. It is about.

In general, a vehicle has several doors. This door is relatively weak compared to other parts, so it is reinforced in various forms.

FIG. 1 is a view showing a general door of a vehicle, and FIG. 2 is a view according to FIGS. The door 10 is shown in FIG. The door 10 is usually rotatably installed on the side of the vehicle so as to be opened or closed. Since the door 10 is relatively weak compared to other parts, the door 10 is reinforced in various forms for the safety of the passenger.

As shown in FIG. 2, the door 10 includes an outer panel 12. This outer panel 12 is a part constituting the outer surface of the vehicle. This outer panel 12 is mainly made of plastic. The inner panel 14 is coupled to the outer panel 12 facing each other.

As shown, a reinforcement part 13 is formed on one inner side of the outer panel 12 to protrude inward, and the pads 16 are attached to the reinforcement part 13 at predetermined intervals. The reinforcement part 130 and the pad 16 are for increasing the rigidity of the outer panel 12.

In the door having the conventional outer panel reinforcement structure described with reference to FIGS. 1 and 2, the outer panel 12 is mainly made of plastic during side impact, and the reinforcement degree thereof is not sufficient enough to easily deform or break. That is, the safety of the passengers is reduced.

An object of the present invention is to provide a door outer panel reinforcement structure that increases the safety of passengers against side collisions by supporting the outer panel of the door with sufficient rigidity.

124: second reinforcing member 126: third reinforcing member

An object of the present invention is an outer panel reinforcing structure of a door having an outer panel constituting an outer surface and an inner panel coupled to the outer panel to form an inner surface, wherein the outer panel is formed in one side of the inner surface of the outer panel and A first reinforcing member joined along the side inner surface, a second reinforcing member joined along the other side inner side and bent in a letter-shaped shape, and a third formed along the lower side inner surface of the outer panel in the form of a lower side inner surface It can be achieved by the door outer panel reinforcement structure characterized in that it comprises a reinforcement member.

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

3 is a view showing the outer panel reinforcement structure of the present invention according to Figure 1 I-I, Figure 4 is a cross-sectional view showing the outer panel reinforcement structure of the present invention according to Figure 1 J-J, Figure 5 is a first K-K is a cross-sectional view showing the outer panel reinforcement structure of the present invention.

3 illustrates one side portion of the door outer panel 112. The first reinforcing member 120 is joined to the inner side surface of the outer panel 112 by a screw 122. The first reinforcing member 120 is molded in the form of one side side inner surface of the outer panel 112, and is joined in the vertical direction along one side side inner surface. The inner panel 114 is coupled to the outer panel 112 inward.

4 illustrates the other side portion of the outer panel 112. The outer side surface of the outer panel 112 is formed in the shape of the letter N and the second reinforcing member 124 is joined along the inner side of the other side. The second reinforcing member 124 is a portion for reinforcing the other side of the door. The inner panel 114 is coupled to the outer panel 112.

5 illustrates a lower side portion of the outer panel 112. The inner side surface of the outer panel 112 is molded in the form of the inner side of the lower side of the outer panel 112, and the third reinforcing member 126 is joined to the inner side of the lower side. The third reinforcing member 126 is for reinforcing the lower side of the door. The inner panel 114 is coupled to the outer panel 112.

The first to third reinforcing members 120, 124, and 126 described in FIGS. 3 to 5 may be made of steel. That is, the first to third reinforcing members 120, 124 and 126 made of steel are reinforced along the inner edge of the outer panel 112 made of plastic, thereby increasing the rigidity of the door.

As can be seen from the above description, the vehicle having the door outer panel reinforcement structure according to the present invention increases the rigidity of the door corresponding to the side collision, thereby increasing the safety of the passenger.
