Description

자동차의 카울사이드부 보강구조{Reinforcing structure of cowl side area in automobile}Reinforcing structure of cowl side area in automobile}

본 발명은 자동차의 카울사이드부 보강구조에 관한 것으로서, 보다 상세하게는 차폭방향으로 배치되는 카울컴플레이트와 차길이방향으로 배치되는 사이드컴플레이트가 서로 결합되는 카울사이드부에 별도의 보강부재를 추가로 설치하여 카울컴플레이트의 횡강성을 증대시키기 위한 자동차의 카울사이드부 보강구조에 관한 것이다.The present invention relates to a cowl side reinforcement structure of a vehicle, and more specifically, to a cowl side plate disposed in the vehicle width direction and a side reinforcement disposed in the vehicle length direction, an additional reinforcement member is added to the cowl side portion. The present invention relates to a cowl side reinforcement structure of a vehicle for increasing the lateral rigidity of the cowl plate.

일반적으로, 자동차의 전방에는 도1에 도시된 바와 같이 엔진 및 동력전달계가 탑재되도록 엔진룸(1)이 마련되며, 상기 엔진룸(1)에는 엔진룸(1)과 차실내(2)를 구획짓는 카울컴플레이트(10)가 차체의 횡방향, 즉 차폭방향을 따라 길게 배치된다.In general, an engine room 1 is provided at the front of the vehicle to mount an engine and a power transmission system as shown in FIG. 1, and the engine room 1 is divided into an engine room 1 and an interior of the vehicle compartment 2. The building cowl plate 10 is arranged long along the transverse direction of the vehicle body, that is, along the vehicle width direction.

상기 카울컴플레이트(10)는 다시 종방향, 즉 차체 길이방향으로 배치된 사이드컴플레이트(20)와 그 끝단이 서로 결합되는 구조를 갖는데, 이 결합부위를 카울사이드부(A)라고 하며, 그 결합상태는 도2a 및 도2b에 잘 나타나 있다.The cowl cum plate 10 has a structure in which the side comb plate 20 and its ends are coupled to each other in the longitudinal direction, that is, in the longitudinal direction of the vehicle body, and this coupling part is called a cowl part A. The coupling state is shown well in FIGS. 2A and 2B.

도2a는 도1의 "A"부위를 보인 종래 카울사이드부의 사시도이고, 도2b는 종래 카울사이드부의 개략 단면도이다.FIG. 2A is a perspective view of a conventional cowlside portion showing the "A" portion of FIG. 1, and FIG. 2B is a schematic cross-sectional view of the conventional cowlside portion.

여기에서 보면, 차폭방향으로 길게 배치되는 카울컴플레이트(10)의 양 끝단은 차체길이방향으로 배치되는 사이드컴플레이트(20)와 결합되는데, 그 결합구조는 도2b에 나타낸 바와 같이 카울컴플레이트(10)의 양 끝단이 절곡된 상태로 사이드컴플레이트(20)에 결합된다.Here, both ends of the cowl plate 10 disposed in the vehicle width direction is coupled to the side plate 20 is arranged in the vehicle body length direction, the coupling structure is as shown in Figure 2b Both ends of the 10) are bent to the side plate 20 in a state bent.

그러나, 상술한 바와 같은 종래의 카울사이드부 결합구조에서는 카울컴플레이트(10)가 사이드컴플레이트(20)에 결합되는 카울사이드부(A)의 결합강성이 작아서 자동차가 선회시에 상기의 카울컴플레이트(10)에서 큰 변위량을 갖는 비틀림모멘트가 발생하여 차체가 크게 쏠리는 문제점이 있었다.However, in the conventional cowlside part coupling structure as described above, the cowlcomb part 10 has a small coupling rigidity of the cowl part A, which is coupled to the side comb plate 20, so that the cowlcomb when the vehicle is turning. There was a problem in that the torsional moment with a large displacement amount in the plate 10 caused the vehicle body to be greatly inclined.

본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적은 카울컴플레이트와 사이드컴플레이트가 결합되는 부위인 카울사이드부를 별도의 보강부재로 보강하여 카울사이드부의 결합강성을 증대시킴으로써 궁극적으로 카울컴플레이트의 횡강성 증대와 차량 회전시 차체의 쏠림을 방지하는데 있다.The present invention has been proposed in order to solve the problems described above, the object of which is to strengthen the cowl side portion by reinforcing the cowl side portion, which is the portion where the cowl plate and the side plate is combined with a separate reinforcement member ultimately This is to increase the lateral stiffness of the cowl plate and to prevent the body from tipping when the vehicle rotates.

상기의 목적을 달성하기 위한 본 발명은, 엔진룸과 차실의 경계부위에 카울컴플레이트가 차폭방향으로 설치되고, 상기 카울컴플레이트의 양 끝단부위에 차체길이방향으로 놓이는 사이드컴플레이트가 상기 카울컴플레이트와 결합되는 자동차의 카울사이드부 결합구조에 있어서, 상기 카울컴플레이트와 상기 사이드컴플레이트가 결합되는 부위를 보강하여 카울컴플레이트의 횡강성이 증대되도록 상기 카울컴플레이트와 사이드컴플레이트의 결합부위에는 "ㄱ"자 형상으로 절곡된 보강부재가 설치된 자동차의 카울사이드부 보강구조이다.The present invention for achieving the above object, the cowl cum plate is installed in the vehicle width direction at the boundary between the engine compartment and the vehicle compartment, the side comm plate which is placed in the vehicle body length direction on both ends of the cowl plate is the cowl com In the coupling structure of the cowl side part of the automobile coupled to the plate, the coupling part of the cowl plate and the side plate to increase the lateral rigidity of the cowl plate by reinforcing the portion where the cowl plate and the side plate is coupled There is a cowl side reinforcement structure of the car is installed in the reinforcement member bent in a "b" shape.

이하, 본 발명의 특징적인 기술구성을 첨부된 도면에 의거하여 보다 상세하게 설명한다.Hereinafter, the technical configuration of the present invention will be described in more detail with reference to the accompanying drawings.

도3a는 도1의 "A"부위를 보인 본 발명에 따른 카울사이드부의 사시도이고, 도3b는 본 발명에 따른 카울사이드부의 개략 단면도이다.Fig. 3A is a perspective view of a cowlside part according to the present invention showing the "A" part of Fig. 1, and Fig. 3B is a schematic sectional view of the cowlside part according to the present invention.

도3a 및 도3b를 참조하여 본 발명을 설명하면, 엔진룸과 차실의 경계부위에 차폭방향으로 카울컴플레이트(10)가 설치되고, 상기 카울컴플레이트(10)의 양 끝단부는 차체 길이방향으로 설치된 사이드컴플레이트(20)와 결합된다.Referring to FIGS. 3A and 3B, the cowl plate 10 is installed in the vehicle width direction at the boundary between the engine compartment and the vehicle compartment, and both ends of the cowl plate 10 are disposed in the vehicle body length direction. It is coupled with the installed side plate 20.

이때, 상기 카울컴플레이트(10)의 양 끝단부는 절곡되어 상기 사이드컴플레이트(20)에 결합된다.At this time, both ends of the cowl plate 10 is bent and coupled to the side plate 20.

한편, 상기 카울컴플레이트(10)와 사이드컴플레이트(20)가 결합된 카울사이드부(A)에는 카울컴플레이트(10)와 사이드컴플레이트(20)의 결합강성을 증대시키기 위하여 별도의 보강부재(30)가 추가로 설치된다.On the other hand, in the cowl side portion (A) to which the cowl plate 10 and the side plate 20 is coupled, a separate reinforcing member to increase the coupling rigidity of the cowl plate 10 and the side plate 20 (20) 30 is further installed.

상기 보강부재(30)는 상기 카울컴플레이트(10)와 사이드컴플레이트(20)가 이루는 면에 설치 가능하도록 "ㄱ"자 형상으로 절곡 형성된다.The reinforcing member 30 is formed to be bent in a "b" shape to be installed on the surface formed of the cowl plate 10 and the side plate 20.

따라서, 상기 카울컴플레이트(10)와 사이드컴플레이트(20)가 결합되는 카울사이드부는 상기 보강부재(30)에 의하여 결합강성이 증대되며, 이에 의하여 카울컴플레이트(10)의 횡강성 또한 증대되어 상기 카울컴플레이트(10)는 차량이 선회시에도 잘 비틀리지 않게 되는 것이다.Therefore, the cowl side portion to which the cowl plate 10 and the side plate 20 are coupled is increased by the reinforcing member 30, thereby increasing the lateral rigidity of the cowl plate 10. The cowl plate 10 will not be twisted well even when the vehicle is turning.

상술한 바와 같이 본 발명에 따른 자동차의 카울사이드부 보강구조에 의하면, 차체의 차폭방향으로 설치되는 카울컴플레이트의 양 끝단부와 차체의 차길이방향으로 설치되는 사이드컴플레이트가 서로 결합되는 카울사이드부에 카울컴플레이트와 사이드컴플레이트의 결합강성을 증대시키기 위한 보강부재를 별도로 추가 설치하여 상기 카울컴플레이트의 횡강성을 증대시킴으로써 자동차가 선회시 원심력이 작용하는 방향으로 쏠리지 않고 회전 안정성이 증대되는 특유의 효과가 있다.As described above, according to the cowl side reinforcement structure of the vehicle according to the present invention, the cowl side in which both end portions of the cowl plate installed in the vehicle width direction and the side plate plates installed in the vehicle length direction of the vehicle body are coupled to each other. By additionally installing a reinforcing member to increase the coupling stiffness of the cowl plate and the side plate plate to increase the lateral stiffness of the cowl plate to increase the rotational stability without being oriented in the direction of centrifugal force when the car turns Has a unique effect.
