Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a side body panel reinforcing structure for automobile,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a quarter panel reinforcement structure for an automobile side body, and more particularly, to an automobile having a three-row or four-row seat, And a quarter-panel reinforcing structure of the side body.

.

In the automobile industry, the need to improve fuel efficiency has been increased due to the influence of the high-priced market environment, and accordingly, the weight-saving design of the vehicle body has become important.

There has been a growing demand for the development of an optimized body structure that can improve the strength and stiffness of the vehicle body structure while achieving weight reduction while satisfying the collision laws reinforced therefrom.

For this purpose, the application rate of ultra-high tensile strength steel with a tensile strength of 590 MPa or more is increasing, and the thickness of the panel is reduced by applying such a material having high tensile strength, thereby improving fuel efficiency and impact performance by reducing weight.

However, unlike the impact performance, the stiffness of the vehicle body is not proportional to the strength of the material. Therefore, weight reduction for replacement of the material may lead to deterioration of the rigidity and soundproofing performance of the vehicle without considering the stiffness of the vehicle body.

Therefore, it is necessary to implement a lightweight, high rigidity body structure by applying a super high tensile steel plate of simple material and optimizing the body structure rather than reducing the thickness.

Accordingly, a door impact beam is installed inside the front door and the rear door to reinforce the rigidity, thereby protecting the passenger in the first and second rows from impact due to the side collision.

However, as described above, the passenger on the first row and the second row can be prevented from impacting due to the side impact by absorbing the impact beam of the door as much as possible, and in the case of the passenger sitting on the third or fourth row seat in the automobile having seven passengers or more, As a result, the impact caused by the side collision is transmitted to the passenger as it is, leading to a serious injury.

That is, the rear portion of the side body having three rows or four rows of seats in a car having a capacity of seven passengers or more in the past is formed by simply arranging the reinforce C pillar 11 and the reef force D pillar 12 on both sides of the quarter panel 10 When the impact force due to the side collision is transmitted, the quarter panel 100 is pushed inward while not collapsing the impact force, and the impact force is transmitted to the passenger, thereby causing a serious injury to the passenger.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a quaternary panel structure for reinforcing a quarter panel of a side body, So as to minimize the injuries of passengers sitting on the vehicle side body.

In order to achieve the object of the present invention, there is provided an automobile side body including a Rainforth C filler and a Rainforth D filler provided with three rows or four rows of sheets between both quarter panels, A first bracket provided with a welded portion to be welded and having a beam seating groove formed on the other side of the welded portion bent at a predetermined angle; A second bracket having a joint portion welded to the reinforce D filler at one side and a beam seating groove formed at the other side of the joint portion bent at a predetermined angle; An impact beam in the form of a round bar formed at a predetermined length so that both ends are placed on and welded to the beam seat of the first bracket and the beam seat of the second bracket; The above object can be achieved effectively.

Since the impact beam is installed across the quarter panel to reinforce the strength of the quarter panel, the impact force generated during the side collision can be absorbed and canceled by the quarter panel as much as possible so that the passenger sitting on the third or fourth seat It is possible to minimize the injuries.
