본 고안은 자동차의 프론트시트 크로스멤버(front seat cross member)에 관한 것으로, 더 상세하게는 프론트시트 크로스멤버의 강성을 증대시켜, 차량의 측면충돌시 센터필러 하단부의 전체적인 강성증대로 승객 상해치를 저감하여 안전성을 향상시켜, 또한 프론트시트 크로스멤버의 제작공정을 단순화하여 성형성 향상 및 원가를 절감할 수 있도록 한 자동차의 프론트시트 크로스멤버 보강구조에 관한 것이다.The present invention relates to a front seat cross member of a vehicle, and more particularly, to increase the rigidity of the front seat cross member, thereby reducing the passenger injury by increasing the overall rigidity of the lower portion of the center pillar in the event of a side collision of the vehicle. The present invention relates to a front seat cross member reinforcement structure of an automobile, which can improve safety and further simplify the manufacturing process of the front seat cross member to improve moldability and reduce cost.

일반적으로 자동차의 충돌사고시 승객의 안전을 확보하기 위한 테스트로는 전방충돌과 측면충돌이 있으며, 이는 자동차의 안전성을 확보하는 중요한 요소로서 이미 각 나라에서는 이러한 충돌시의 안전치를 법규화하여 수입규제 등의 큰 항목으로 이용하고 있다.In general, tests to ensure the safety of passengers in the event of a car crash include front and side collisions, which are important factors to secure car safety. We use with big item of.

그러나, 현재 생산되고 있는 자동차는 대부분이 전방충돌에 대한 안전치는 어느 정도 확보하고 있으나, 측면충돌에 대한 안전치는 미흡한 실정이다. 즉, 그 원인으로는 측면충돌시 프론트시트 크로스멤버에서 충격력을 제대로 흡수하지 못하므로 인하여 센터필러 하단부의 전체적인 강성이 취약하기 때문이다.However, most of the automobiles currently produced have some safety values for forward collisions, but the safety values for side collisions are insufficient. That is because the overall rigidity of the lower portion of the center pillar is vulnerable because the front seat cross member does not properly absorb the impact force during side collision.

한편, 제1도에서와 같이 자동차의 프론트시트 크로스멤버(1)는 프론트도어(2)와 리어도어(3) 사이에 설치된 센터필러(4)의 하단부에 설치되어 그 상단으로 프론트시트가 설치되는 것으로, 이러한 프론트시트 크로스멤버(1)는 사이드실이너판넬(5)과 센터플로어(6)상에 길이방향으로 용접결합되어 양측의 센터필러(4)를 지지한다.Meanwhile, as shown in FIG. 1, the front seat crossmember 1 of the vehicle is installed at the lower end of the center pillar 4 installed between the front door 2 and the rear door 3 so that the front seat is installed at the upper end thereof. The front seat crossmember 1 is longitudinally welded on the side seal inner panel 5 and the center floor 6 to support the center pillar 4 on both sides.

그러나, 종래의 프론트시트 크로스멤버(1)는 제2도에서와 같이 1피스(piece)의 단품인 일체형으로 형성되었기 때문에, 측면충돌시 강성이 취약하여 충격을 제대로 흡수하지 못하고 쉽게 찌그러지면서 변형되어 센터필러(4)를 지지할 수 없으므로, 이로 인하여 센터필러(4) 하단부의 전체적인 강성이 취약하여 측면충돌시 실내 밀림량이 커져 승객 상해치가 커지고 자동차의 안전성이 떨어지게 되는 문제점이 있었다.However, since the conventional front seat crossmember 1 is formed as a single piece of a single piece as shown in FIG. 2, the front seat crossmember 1 is deformed while being easily crushed due to weak rigidity during side collision and not easily absorbed impact. Since the center pillar 4 cannot be supported, the overall rigidity of the lower portion of the center pillar 4 is weak, resulting in a large amount of indoor jungle during side collisions, resulting in increased passenger injury and a decrease in safety of the vehicle.

또한, 상기와 같이 종래의 프론트시트 크로스멤버(1)는 하나의 단품인 일체형으로 구성되었기 때문에 그 제작공정이 불편하여 성형성 저하 및 원가가 상승하는 문제점이 있었다.In addition, as described above, the conventional front seat crossmember 1 has a problem in that the manufacturing process is inconvenient, and the moldability decreases and the cost increases because it is configured as a single piece.

본 고안의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 안출한 것으로 , 프론트시트 크로스멤버의 강성을 증대시켜, 차량의 측면충돌시 센터필러 하단부의 전체적인 강성증대로 승객 상해치를 저감하여 안전성을 향상시키며, 또한 프론트시트 크로스멤버의 제작공정을 단순화하여 성형성 향상 및 원가를 절감할 수 있도록 한 자동차의 프론트시트 크로스멤버 보강구조를 제공하는 데 있다.The object of the present invention is to solve the above-mentioned drawbacks, and to increase the rigidity of the front seat crossmember, and to reduce the safety of passenger injury by increasing the overall rigidity of the lower center pillar in case of side collision of the vehicle. In addition, the present invention provides a front seat cross member reinforcement structure of a car that can simplify the manufacturing process of the front seat cross member and improve moldability and reduce cost.

상기 목적을 달성하기 위해 본 고안은 센터필러의 하단부를 지지하는 프론트시트 크로스멤버를 센터크로스멤버와, 상기 센터클로스멤버의 외측단에 끼워져 결합되는 보강크로스멤버 및 상기 상기 보강크로스멤버의 외측단에 끼워져 결합되는 사이드크로스멤버의 5피스로 분리하여 프론트시트 크로스멤버의 전체적인 결합강성을 증대시킨 것이다.In order to achieve the above object, the present invention includes a front seat cross member supporting a lower end of a center pillar, a center cross member, a reinforcement cross member fitted to and coupled to an outer end of the center cross member, and an outer end of the reinforcement cross member. By separating the five pieces of the side cross member to be fitted and joined to increase the overall bonding rigidity of the front seat cross member.

이하 첨부된 도면에 따라서 본 고안의 구성과 작용효과를 상세히 설명하면 다음과 같다.Hereinafter, the configuration and the effect of the present invention according to the accompanying drawings in detail.

본 고안은 자동차의 프론트시트 크로스멤버 보강구조는 제3도와 제4도에 도시되는 바와 같이, 센터필러의 하단내측에 위치하여 사이드실이너판넬과, 센터플러어상에 길이방향으로 용접결합되는 프론트시트 크로스멤버(10)에 있어서, 상기 프론트시트 크로스멤버(10)는 상기 센터플로어의 중앙부에 결합되는 센터크로스멤버(11)와, 상기 센터클로스멤버(11)의 외측단에 끼워져 결합되어 외측으로는 경사면(12a)이 일체로 형성되는 보강크로스멤버(12)와, 상기 보강크로스멤버(12)의 외측단에 끼워져 결합되는 사이드크로스멤버(13)로 분리하여 구성된다.According to the present invention, the front seat cross member reinforcement structure of the vehicle is located in the lower end of the center pillar as shown in FIGS. 3 and 4, and the front seat is longitudinally welded on the side seal inner panel and the center plug. In the cross member 10, the front seat cross member 10 is fitted to the outer end of the center cross member 11 and the center cross member 11 is coupled to the center portion of the center floor is coupled to the outside The inclined surface (12a) is formed by separating the reinforcement cross member 12 and the side cross member (13) which is fitted and coupled to the outer end of the reinforcement cross member (12).

이러한 본 고안은 센터크로스멤버(11)의 양측단에 2개의 보강크로스멤버(12)가 각각 끼워져 용접으로 결합되고, 보강크로스멤버(12)의 외측단에는 2개의 사이드크로스멤버(13)가 각각 끼워져 용접으로 결합되는 것으로, 본 고안의 프론트시트 크로스멤버(10)는 5피스로 구성된 각각의 멤버(11)(12)(13)들이 상호 용접으로 결합된다.In the present invention, two reinforcement cross members 12 are fitted to both sides of the center cross member 11, respectively, and are welded together, and two side cross members 13 are respectively provided at the outer ends of the reinforcement cross member 12. By being fitted by welding, the front seat crossmember 10 of the present invention is each member 11, 12, 13 consisting of five pieces are joined by mutual welding.

이와 같이 구성된 본 고안은 차량의 측면충돌시 센터필러가 일차적으로 충격력을 흡수하고, 이어서 나머지 충격은 사이드크로스멤버(13)에서 흡수하여 분산,완화시키며, 이때 사이드크로스멤버(13)를 넘어서는 충격력은 경사면(12a)이 구비된 보강크로스멤버(12)에 흡수되어 완화된다.According to the present invention configured as described above, the center pillar absorbs the impact force during the side collision of the vehicle, and then the remaining impact is absorbed by the side cross member 13 to be dispersed and alleviated, and the impact force beyond the side cross member 13 is The inclined surface 12a is absorbed by the reinforcing cross member 12 and is relaxed.

여기서, 본 고안은 종래 일체형 프론트시트 크로스멤버에 비하여 각각의 멤버(11)(12)(13)들이 용접으로 결합되므로 그 두께가 증대되어 결국적으로 강성이 증대되고, 충격력을 다단계에 걸쳐 흡수하므로 충격흡수 효과가 증대된다.Here, the present invention, since the respective members 11, 12, 13 are joined by welding, compared with the conventional integrated front seat crossmember, the thickness thereof is increased, and ultimately, the rigidity is increased, and the impact force is absorbed in multiple stages. Shock absorption effect is increased.

따라서, 이러한 본 고안은 5피스로 분리된 각각의 멤버(11)(12)(13)들이 상호 용접결합되므로 프론트시트 크로스멤버(10)의 부분적인 강성과 전체적인 결합강성을 증대시키고, 또한 이로 인하여 센터필러 하단부의 강성이 증대되므로 차량의 측면충돌시 실내 밀림량을 최대한 억제시켜 승객 상해치를 저감시키는 동시에 자동차의 안전성을 향상시킨다.Therefore, the present invention increases the partial stiffness and the overall coupling stiffness of the front seat cross member 10 because each of the members 11, 12, 13 separated into five pieces is welded to each other. Since the rigidity of the lower part of the center pillar is increased, the amount of indoor sliding is minimized during side impact of the vehicle, thereby reducing passenger injury and improving vehicle safety.

한편, 상기과 같이 5피스로 분리 구성된 본 고안의 프론트시트 크로스멤버(10)는 각각의 멤버(11)(12)(13)들의 제작공정이 종래 일체형에 비하여 매우 간단하여 성형성이 향상되고, 이로 인하여 원가가 절감된다.On the other hand, the front seat cross member 10 of the present invention, which is separated into five pieces as described above, the manufacturing process of each of the members 11, 12, 13 is very simple compared to the conventional one-piece, and thus the moldability is improved. The cost is reduced.

이상에서 설명한 바와 같이 본 고안은 프론트시트 크로스멤버의 강성을 증대시켜, 차량의 측면충돌시 센터필러 하단부의 전체적인 강성증대로 승개 상해치를 저감하여 안전성을 향상시키며, 또한 프론트시트 크로스멤버의 제작공정을 단순화하여 성형성 향상 및 원가를 절감할 수 있는 매우 유용한 고안이다.As described above, the present invention increases the rigidity of the front seat crossmembers, thereby reducing safety of the car accident by increasing the overall stiffness of the lower center pillar in the event of a side collision of the vehicle, thereby improving safety, and improving the manufacturing process of the front seat crossmembers. It is a very useful design that can simplify and improve moldability and cost.
