Description
본 발명은 승용차차체의 후륜쪽 상부방향으로 연장되는 콰터필러(Quarter Piller ; 일명 C-필러 라 칭함)에 관한 것으로, 더욱 상세하게는 후차체에 설치되는 서스펜션으로부터 작용하는 압력하중을 차체로 골고루 분산시키고 차체의 횡강성과 비틀림 강성을 향상시킨 승용차 차체의 콰터 필터부 보강구조에 관한 것이다.The present invention relates to a quarter-pillar (Quarter Piller; also known as C-pillar) extending in the upper direction toward the rear of the passenger car body, and more particularly, evenly distributed pressure load acting from the suspension installed in the vehicle body to the vehicle body And a quarter filter part reinforcement structure of a passenger car body having improved lateral and torsional stiffness.
일반적으로 승용차의 후차체 쪽에는 B필러와 리어부 사이에 C필러인 콰터필러가 설치되어 있는데, 이 콰터필러는 후륜쪽 휠하우징 상부쪽에서 루프까지 연장되어 설치되는 차체이다.In general, a quaternary filler, which is a C pillar, is installed between the B pillar and the rear of the rear body of the passenger car, which is a vehicle body extending from the upper part of the rear wheel housing to the roof.
한편 차량에서 차체에 주하중을 서스펜션 시스템으로부터 전후/좌우의 네방향으로 나누어 전달됨에 따라 차체는 이 서스펜션 시스템의 지지부 주변차체 구조를 충분히 보강하여 서스펜션으로부터 작용하는 하중을 차체로 골고루 분산시키어 차체의 골격강성을 일정한 수준으로 유지시키도록 되어 있다.Meanwhile, as the main load is transmitted from the suspension system to the vehicle body in four directions, front and rear, right and left, the vehicle body fully reinforces the structure around the support part of the suspension system, and evenly distributes the load acting from the suspension to the vehicle body. It is intended to maintain the stiffness at a constant level.
따라서 이러한 차체 구조를 만족시키기 위해 휠하우징 상부에는 통상적인 보강부재가 설치되어 있다.Therefore, in order to satisfy the vehicle body structure, a conventional reinforcing member is installed on the upper part of the wheel housing.
그러나 종래 후차체의 휠하우징 상부쪽으로 설치되는 콰터필러는 이 휠하우징 상부만 보강시키어 국부적인 보강만 이루어지는 구조로 되어 있는바, 즉 콰터필러의 중간부분까지만 보강구조를 갖추고 있어서 차체 전체의 횡강성 및 비틀림강성등이 상대적으로 부족하여 전체적인 차체 골격 강성을 만족시키기에는 부족한 구조를 갖추고 있다.However, the quaternary fillers installed in the upper part of the wheel housing of the conventional rear car body only have the structure of local reinforcement only by reinforcing the upper part of the wheel housing, that is, the reinforcement structure is provided only to the middle part of the quaternary filler. The torsional rigidity, etc., is relatively insufficient, and the structure is insufficient to satisfy the overall body skeleton rigidity.
이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 후차체의 서스펜션으로부터 작용하는 압력하중을 차체 전반으로 골고루 분산시킬 뿐만 아니라, 차체의 횡강성과 비틀림 강성도 강화시킨 승용차 차체의 과터 필터부 보강구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above-mentioned conventional problems, and the rotor filter of the passenger car body which not only distributes the pressure load acting from the suspension of the rear body evenly throughout the vehicle body, but also strengthens the lateral and torsional rigidity of the vehicle body. The purpose is to provide a secondary reinforcement structure.
도 1은 본 발명에 따른 콰터 필터부 보강구조가 적용된 승용차 후차체의 일부 부분 사시도,1 is a partial partial perspective view of a passenger car rear body to which a quarter filter reinforcement structure is applied according to the present invention;
도 2는 도 1의 I-I선 확대 단면도이다.FIG. 2 is an enlarged sectional view taken along line II of FIG. 1.

상기와 같은 목적을 달성하기 위한 본 발명은 사이드 아우터판넬과 과터 상부인너판넬 사이에 보강재를 갖춘 승용차 차체의 과터필러 보강구조에 있어서, 상기 보강재는 이의 상부쪽이 리어헤더와 루프의 사이드레일까지 연장되어 연결되고 이의 하부쪽은 휠하우징과 연결되는 구조로 되어 있다.The present invention for achieving the above object is an overfill filler reinforcement structure of a vehicle body having a reinforcement between the side outer panel and the upper inner panel of the rotor, the reinforcement is extended to the side rail of the rear header and the roof thereof It is connected to the lower part of the structure is connected to the wheel housing.
이하 본 발명을 첨부된 예시 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명이 적용된 승용차의 후차체 부분 사시도이고, 도 2는 도 1의 I-I선에 따른 확대 단면도이다.1 is a partial perspective view of a rear body of a passenger car to which the present invention is applied, and FIG. 2 is an enlarged cross-sectional view taken along line I-I of FIG. 1.
본 발명은 도면에 도시된 바와 같이 사이드 아우터판넬(1)과 과터 상부인너판넬(2)사이에 보강재가 내장 설치되어 이루어진 승용차 차체의 콰터필러 보강구조에 있어서, 상기 보강재(3)는 이의 상부쪽이 리어헤드(4)와 루프(5)의 사이드레일(6)까지 연장되어 연결되고, 이의 하부쪽은 휠하우징(7)에 연결되어 있다.According to the present invention, in the quarter reinforcement structure of a passenger car body in which a reinforcement is provided between the side outer panel 1 and the upper upper inner panel 2 as shown in the drawing, the reinforcement 3 is an upper side thereof. The rear head 4 and the side rails 6 of the loop 5 extend and are connected, and the lower side thereof is connected to the wheel housing 7.
그리고 상기 보강재(3)는 사이드 아우터 판넬(1)과 과터 상부인너판넬(2)사이에 내장되면서 폐단면 구조를 갖도록 벤딩부(8)가 형성되어 있으며, 상기 보강재(3)가 접하는 차체의 부재들과는 용접과 같은 부착수단으로 결합되어져 있다.The reinforcement 3 is formed between the side outer panel 1 and the upper upper inner panel 2 and has a bent portion 8 to have a closed cross-sectional structure, and the member of the vehicle body in contact with the reinforcement 3 is formed. These are combined with attachment means such as welding.
따라서 상기 보강재(3)의 상부가 루프(5)의 사이드레일(6)까지 연장되어 결합됨에 따라 휠하우징(7)의 하부쪽에 위치하는 서스펜션(도면에 도시하지 않았음)으로부터 작용하는 압력하중을 이 보강재(3)를 통하여 차체 전반으로 분산 전달시킬 뿐만 아니라, 이로 인하여 차체의 횡강성과 비틀림 강성을 강화시키도록 되어있다.Therefore, as the upper portion of the reinforcement 3 extends to the side rails 6 of the loop 5 and is coupled, the pressure load acting from the suspension (not shown in the drawing) located at the lower side of the wheel housing 7 is applied. Through this reinforcing material (3), as well as distributed transmission to the overall body, thereby to strengthen the lateral rigidity and torsional rigidity of the vehicle body.
상기와 같이 본 발명에 따른 승용차 차체의 콰터 필러부 보강구조는 후차체의 서스펜션에서 작용하는 하중을 차체로 골고루 분사시키면서 차체의 횡강성과 비틀림 강성에 대한 보유지지력을 향상시킨 잇점이 있다.As described above, the quarter-pillar reinforcement structure of the passenger car body according to the present invention has an advantage of improving the holding force against the lateral rigidity and the torsional rigidity of the vehicle body while uniformly injecting the load acting on the suspension of the rear body to the vehicle body.
