The present invention relates to an auto body door frame, and more particularly, to a front opening upper end reinforcement structure of a car door frame to increase vehicle safety by reinforcing the front opening upper end of the door frame.

In general, various collision tests are conducted for the safety of passengers in the event of a vehicle crash. At this time, the front collision and side collision tests are mainly tested to regulate the automobile safety level, and the automobile satisfies the safety level regulations during production However, in the present invention, it is intended to reveal that the front reinforcing upper reinforcing structure of the car door frame is important.

1 is a perspective view showing the front opening end of the automobile door frame, wherein part A is the front opening upper end of the automobile door frame.

In the related art, as shown in FIG. 2, the front opening A of the vehicle door frame includes a side outer panel 100, a side inner loop frame 200 positioned below the side outer panel 100, Since the front pillar inner panel 300 and the side inner panel 400 coupled to both ends of the side inner loop frame 200 are configured, that is, the front opening A is reinforced with a two-stage structure. Due to the weak rigidity of the structure, there was a problem in that safety value regulations could not be satisfied due to excessive distortion and deformation during side and impact.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a front opening upper end reinforcement structure of a car door frame that can provide convenience to increase vehicle safety by reinforcing the front opening upper end of the door frame. will be.

The present invention and the side outer panel to achieve the above object; The front pillar reinforcement panel and the center pillar reinforcement panel which are located at the bottom of the side outer panel and are mutually coupled, and the front pillar inner panel and the side which are positioned at the bottom of the mutually coupled front pillar reinforcement panel and the center pillar reinforcement panel and are mutually coupled. It is achieved by providing a front opening upper reinforcement structure of the vehicle door frame, including the inner panel, in which the front opening is constructed.

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

3 is a front opening top reinforcement structure of the automobile door frame according to the present invention, which includes a side outer panel 10; A front pillar reinforcement panel 20 and a center pillar reinforcement panel 30 positioned below the side outer panel 10 and coupled to each other; Located at the bottom of the mutually coupled front pillar reinforcement panel 20 and the center pillar reinforcement panel 30 includes a front pillar inner panel 40 and a side inner panel 50 coupled to each other and the front opening (A) is It is composed.

Next, the effect of the present invention will be described with reference to FIG.

As shown in FIG. 3, the present invention is because the front pillar reinforcement panel 20 and the center pillar reinforcement panel 30 are installed to be coupled between the side outer panel 10 and the side inner panel 50, that is, the side outer Since the front pillar reinforcement panel 20 and the center pillar reinforcement panel 30 are coupled to each other between the panel 10 and the side inner panel 50 to serve as a reinforcement, rigidity is increased.

Therefore, the present invention has a structure of the front opening (A) as shown in Figure 3 compared to the conventional two-stage structure of the present invention consists of a three-stage structure, to prevent the occurrence of distortion and deformation excessive during side impact and front impact Therefore, it is possible to increase the safety of the vehicle by satisfying the safety regulations in the event of a vehicle crash.

The present invention as described above is a useful design that can provide convenience to increase the vehicle safety by reinforcing the front opening upper end of the door frame.
