The present invention relates to a door opening frame of an automobile. In particular, a reinforcing bracket is mounted at the lower end of the center pillar of the door opening frame to increase structural rigidity, thereby effectively resisting the impact energy applied to the side collision of the vehicle, thereby occupying a passenger or the like. The present invention relates to a door opening frame reinforcement structure of a vehicle, which is capable of protecting the vehicle more safely.

In general, the vehicle body is a part that forms the exterior of the vehicle and is composed of a car compartment, an engine compartment, a trunk compartment, a fender, etc., and is divided into a front body, a center body, and a rear body along the longitudinal direction of the vehicle.

The front body consists of an inner plate portion having a dash panel, a wheel house and a front fender, and an outer plate portion formed of a hood and a front end panel, and the center body has an external force except that a driving device is installed behind the floor. Since it is hardly received, it is formed into a box shape by pressing a thin plate, and is composed of a floor panel, a side panel, a roof panel, a cowl panel and a door, while the rear body is formed of a rear floor panel, a rear fender and a lower back panel. Consists of.

Here, the side panel constituting the central vehicle body is such that the door opening frame, the side inner panel and the side outer panel are welded to each other to form a part of the vehicle body, and the conventional door opening frame is shown in FIG. As described above, the rear opening portion 5 is formed between the front pillar 2 and the center pillar 3 of the door opening frame 1 and the center pillar 3 and the rear pillar 4, respectively. The side outer panel 6 is attached adjacent to the pillar 4, and the side inner panel 7 is erected in the vertical direction at the lower end of the center pillar 3 as shown in the cross-sectional view in FIG. One end is attached by welding, and the other end of the side inner panel 7 is attached by welding the floor side panel 8 and the seat belt mounting reinforcement bracket 9. .

However, in the above conventional door opening frame structure, the lower part of the door opening frame, which impacts the front part of the collision vehicle during the side collision of the vehicle and impacts, has a weak structural rigidity, effectively resisting collision energy, thereby protecting passengers and the like. There is a drawback that the following is inadequate, that is, the lower end of the door opening frame 1 is not properly supported, and an empty space is formed between the side inner panel 7 and the floor side panel 8 so that the structural rigidity is weak. It was because.

The present invention has been devised to solve the above-mentioned shortcomings, and a reinforcing bracket is installed at the lower end of the center pillar of the door opening frame, in which the front part of the impulse vehicle collides with the front part of the impulse vehicle at the time of the side collision of the car. It is an object of the present invention to provide a door opening frame reinforcement structure of a vehicle that can effectively respond to a collision of the side of the vehicle to protect the occupants and the like more safely.

The present invention for achieving the above object is made of a structure in which a door opening is formed between the front pillar and the center pillar and between the center pillar and the rear pillar, respectively, and the side outer panel is attached adjacent to the rear pillar. At the lower end of the center pillar, one end is welded to the center pillar by standing upright so that the other end of the side inner panel is welded together to the floor side panel and the seat belt mounting reinforcement bracket. In the door opening frame of an automobile, a reinforcement bracket is installed in the empty space to increase structural rigidity by integrally connecting the lower end of the center pillar to the floor side panel, the seat belt mounting reinforcement bracket and the side inner panel. It is structured to be.

The reinforcing bracket includes a lower flange bent downward at the front end of the plate body, an upper flange bent upward at the rear end, and a side flange which is integrally extended and bent at both side ends, so as to be horizontal in the empty space. The lower flange is welded to the lower end of the center pillar while being received in the squeezing direction, and the upper flange is welded together to the welded portion of the floor side panel, the seat belt mounting reinforcement bracket and the side inner panel, and the side flange is the center pillar. It is welded to the inner side of the lower end of the center pillar is to connect the bottom side panel, the seat belt mounting reinforcement bracket and the side inner panel integrally.

Accordingly, the door opening frame is supported during side collision of the vehicle to reduce deformation and effectively disperse impact energy to the vehicle body, thereby more effectively protecting the occupants.

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

1 is a schematic perspective view of a door opening frame equipped with a reinforcing bracket for increasing structural rigidity at a lower end of a center pillar according to the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. A schematic perspective view of the reinforcing bracket, i.e. between the front pillar (2) and the center pillar (3) of the door opening frame (1) and between the center pillar (3) and the rear pillar (4), respectively The side outer panel 6 is attached to the rear pillar 4 adjacent to the rear pillar 4, and the side inner panel 7 is erected in a vertical direction at the lower end of the center pillar 3 so that one end portion thereof is formed. In addition to the welding, the side end panel 8 and the seat belt mounting reinforcement bracket 9 are attached to the other end of the side inner panel 7 by welding.

The reinforcement bracket 11 is mounted in the empty space 10 in which the lower end portion of the center pillar 3 and the side inner panel 7 and the seat belt mounting reinforcement bracket 9 are formed. By increasing structural rigidity, it is possible to effectively respond to the side impact of the car.

In other words, the reinforcing bracket 11 has a lower flange 11b bent downward to the front end of the plate body 11a, an upper flange 11c bent upward to the rear end, and integrally extended to both side ends. With the side flange 11d, it is received in the direction transverse to the empty space 10 as shown in detail in FIG. 2 and the lower flange 11b is welded to the lower end of the center pillar (3) The upper flange 11c is welded together to a portion where the floor side panel 8, the seat belt mounting reinforcement bracket 9 and the side inner panel 7 are welded together, and the side flange 11d is the center pillar 3 The lower end of the center pillar 3 is welded to the floor side panel 8, the seat belt mounting reinforcement bracket 9 and the side inner panel 7 integrally.

In the empty space 10 formed by the lower end of the center pillar 3 of the door opening frame 1, the floor side panel 8, the seat belt mounting reinforcement bracket 9 and the side inner panel 7 as described above. When the collision vehicle collides with the lower end of the center pillar 3 and impacts the side pillar of the vehicle as the reinforcement bracket 11 is mounted, the reinforcement bracket 11 properly supports the lower end of the center pillar 3. By absorbing the impact, the impact energy is distributed to other parts of the vehicle body, thereby reducing the deformation of the door opening frame, and reducing the impact on the occupants, thereby protecting it more safely.

As described above, according to the door opening frame reinforcement structure of a vehicle according to the present invention, a reinforcement bracket is mounted on the lower end of the center pillar of the door opening frame so that the center pillar is integrally connected to other parts of the vehicle body and supported. In the event of a side collision, the door opening frame is supported to reduce deformation and to effectively distribute impact energy to the vehicle body, thereby protecting passengers and the like.
