Description

차량용 대쉬패널{DASH PANEL FOR VEHICLE}[0001] DASH PANEL FOR VEHICLE [0002]

본 발명은 차량용 대쉬패널에 관한 것으로, 보다 상세하게는 서로 다른 소재의 패널을 용접을 통해 견고하게 결합할 수 있도록 하는 차량용 대쉬패널에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dash panel for a vehicle, and more particularly, to a dash panel for a vehicle which allows a panel of different materials to be firmly coupled through welding.

최근에는 자동차는 크게 나누어 차체와 새시로 구성되어 있으며, 차체는 자동차의 외형이 되는 부분으로서 차실, 기관실, 트렁크실, 펜더등으로 구성된다.In recent years, automobiles are largely divided into body and chassis, and the body is composed of a car, an engine room, a trunk room, and a fender.

이러한 차체는 다시 앞차체, 중심차체, 뒤차체로 구분되며, 앞차체의 엔진실과 중심차체의 승객실로 분리되는 대시패널의 상측면과 중심차체의 계기판이 설치되는 인스트루먼트 패널의 전방면에 카울패널이 체결된다.The vehicle body is further divided into a front body, a center body, and a rear body, and the upper surface of the dash panel separated from the engine compartment of the front body and the passenger compartment of the central body body and the front panel of the instrument panel, Respectively.

카울패널은 원드실드 글래스 외측 전면, 즉 와이퍼 블레이드가 설치된 부분의 하측에 외부로 노출된다.The cowl panel is exposed to the outside on the outer surface of the wedge-shaped glass, that is, below the portion where the wiper blade is installed.

또한, 대쉬패널은 상부대쉬패널부과 하부대쉬패널부로 구분되며, 상부대쉬패널부가 카울과 하부대쉬패널부에 고정된다.The dash panel is divided into an upper dash panel portion and a lower dash panel portion, and the upper dash panel portion is fixed to the cowl and the lower dash panel portion.

구체적으로, 대쉬패널은 엔진룸과 차실을 구획하는 패널로서, 조향장치나 여러 종류의 케이블 및 공조기의 덕트 등이 통과하도록 형성되며, 공조유닛과 페달장치 및 크래쉬 패드 등이 장착된다.Specifically, the dash panel is a panel for partitioning an engine room and a vehicle room, and is formed so as to pass through a steering device, various kinds of cables, ducts of an air conditioner, etc., and an air conditioning unit, a pedal device, a crash pad and the like are mounted.

이러한, 대쉬패널은 엔진룸에서 발생하는 소음이 차실 내부로 전달되지 않도록 차단하는 역할을 하기 때문에 대쉬 패널의 강성은 물론 방음성능이 중요하게 고려된다.Since the dash panel serves to prevent the noise generated in the engine room from being transmitted to the interior of the vehicle, the dash panel as well as the soundproof performance are considered important.

특히, 대쉬패널은 안전성을 확보하기 위하여 2장의 패널을 상호 접합시켜 제작하게 된다. 그리고 2장의 패널을 접합하기 위하여 레이저 용접, 스폿 용접, 셀프 피어싱 리벳, 본딩 접합 등을 사용하게 된다.Particularly, in order to secure safety, the dash panel is manufactured by mutually joining two panels. Laser welding, spot welding, self-piercing rivets, and bonding bonding are used to join the two panels.

그런데, 이와 같은 종래기술의 대쉬패널은 각기 다른 소재의 패널을 접합하기가 매우 어려울 뿐만 아니라, 접합부위의 접합력이 충분히 확보되지 못하는 문제점이 있다.However, such a conventional dash panel is very difficult to join panels of different materials, and there is a problem that a bonding force of a bonding site can not be sufficiently secured.

따라서, 이를 개선할 필요성이 요청된다.Therefore, there is a need to improve this.

한편, 국내 등록특허공보 제10-1288869호(등록일:2013년07월17일)에는 "다층 복합 판재"가 개시되어 있다.

이러한 본 실시예에 따른 차량용 대쉬패널(100)은 중량을 감소시킬 수 있도록 재질이 다른 복수의 평판을 접합한 접합제진강판에 의해 제작된다. 이때, 재질이 다른 평판은 용접 등과 같은 접합방식을 통해 상호 접합된다.The dash panel 100 for a vehicle according to the present embodiment is made of a bonded vibration damping steel plate in which a plurality of flat plates having different materials are bonded to reduce weight. At this time, flat plates having different materials are bonded to each other through a bonding method such as welding.

이를 위하여, 본 실시예에 따른 차량용 대쉬패널(100)은 금속패널(110)과, 복합패널(120)과, 접합부재(130)와 접합력 향상부(140)를 포함한다.The dash panel 100 for a vehicle according to the present embodiment includes a metal panel 110, a composite panel 120, a bonding member 130, and a bonding force improving unit 140.

금속패널(110)은 금속에 의해 제작되며, 용접을 통해 복합패널(120)과 접합된다. 본 실시예에 따른 금속패널(110)은 그 두께가 0.8mm이고, 일단부에 복합패널(120)이 접합되며, 복합패널(120)과 접합된 후 프레싱 성형된다.The metal panel 110 is made of metal and is bonded to the composite panel 120 through welding. The metal panel 110 according to the present embodiment has a thickness of 0.8 mm. The composite panel 120 is bonded to one end of the metal panel 110, and is then press-formed after being bonded to the composite panel 120.

본 실시예에 따른 금속패널(110)은 1.8GPa급 HPF강 단일소재에 의해 제작되는 것이 바람직하다.It is preferable that the metal panel 110 according to the present embodiment is manufactured by a single HPF steel material of 1.8 GPa class.

복합패널(120)은 일단부가 금속패널(110)에 중첩되며, 용접과 접합력 향상부(140)를 통해 금속패널(110)과 접합된다.One end of the composite panel 120 is overlapped with the metal panel 110 and is joined to the metal panel 110 through the welding and bonding force improving part 140.

이러한 복합패널(120)은 금속패널(110)과의 접합력이 향상되도록 단차부(121)가 형성되며, 단차부(121)가 금속패널(110)과 중첩된다. 또한, 복합패널(120)은 단차부(121)와 금속패널(110) 사이에 접합부재(130)가 구비된다.The composite panel 120 is formed with a step 121 to improve the bonding strength with the metal panel 110 and the step 121 is overlapped with the metal panel 110. The composite panel 120 is provided with a joining member 130 between the step 121 and the metal panel 110.

본 실시예에 따른 복합패널(120)은 알루미늄 또는 알루미늄 합금에 의해 1.2mm의 두께를 가지도록 제작될 수 있으며, 대쉬패널(100)의 중량을 감소시키는 기능을 수행한다.The composite panel 120 according to the present embodiment can be manufactured to have a thickness of 1.2 mm by aluminum or an aluminum alloy and functions to reduce the weight of the dash panel 100.

접합부재(130)는 단차부(121)와 금속패널(110) 사이에 도포되어 금속패널(110)과 복합패널(120)을 접합시키게 된다. 이러한 접합부재(130)는 복합패널(120)과 금속패널(110)을 용접할 때 발생하는 열에 의해 경화되어 금속패널(110)과 복합패널(120)을 접합시키게 된다.The joining member 130 is applied between the step portion 121 and the metal panel 110 to bond the metal panel 110 and the composite panel 120 together. The bonding member 130 is cured by heat generated when the composite panel 120 and the metal panel 110 are welded to bond the metal panel 110 and the composite panel 120 together.

접합력 향상부(140)는, 용접에 의해 접합되는 복합패널(120)의 단차부(121)와 금속패널(110)의 접합력을 향상시키게 된다. 이를 위하여 본 실시예에 따른 접합력 향상부(140)는 용접시 용해되는 용접액이 주입되도록 용접액 유입홀(141)을 구비한다.The bonding force improving section 140 improves the bonding force between the step portion 121 of the composite panel 120 and the metal panel 110 bonded by welding. To this end, the welding force improving part 140 according to the present embodiment is provided with a welding liquid inlet hole 141 so as to inject a welding liquid dissolved in welding.

용접액 유입홀(141)은 단차부(121)와 금속패널(110)을 용접시 용접액이 원활하게 유입되도록 단차부(121)의 끝단에 이격되게 복수개 형성된다.The welding liquid inlet hole 141 is formed to be spaced apart from the end of the step portion 121 so that the welding liquid flows smoothly when the step portion 121 and the metal panel 110 are welded.

상기와 같이 구성되는 본 발명의 일 실시예에 따른 차량용 대쉬패널의 제조방법을 설명한다.A method of manufacturing a dash panel for a vehicle according to an embodiment of the present invention will be described.

먼저, 복합패널(120)의 끝단부를 절곡하여 단차부(121)를 형성하고, 단차부(121)의 단부를 가공하여 용접액 유입홀(141)을 형성한다. 이때, 복합패널(120)은 1.2mm, 금속패널(110)은 0.8mm의 두께로 형성된다.First, a stepped portion 121 is formed by bending an end of the composite panel 120, and an end of the stepped portion 121 is processed to form a welded liquid inflow hole 141. At this time, the composite panel 120 is formed to a thickness of 1.2 mm and the metal panel 110 is formed to a thickness of 0.8 mm.

그리고 단차부(121)와 접합되는 금속패널(110) 부위와 단차부(121) 중 어느 일면에 접합부재(130)를 도포한다.The joining member 130 is applied to one side of the metal panel 110 and the step 121 joined to the step 121.

이후, 금속패널(110)과 복합패널(120)의 단차부(121)를 중첩하고, 단차부(121)와 금속패널(110)을 용접하여 단차부(121)와 금속패널(110)을 접합한다. 이때, 접합부재(130)가 용접시 발생하는 열에 의해 경화되면서 금속패널(110)과 단차부(121)를 접합시키며, 금속 등의 구조재료의 접합에서 고온에도 높은 강도를 나타낸다.Thereafter, the metal panel 110 is overlapped with the step 121 of the composite panel 120, the step 121 is welded to the metal panel 110, and the step 121 is joined to the metal panel 110 do. At this time, the joining member 130 is cured by the heat generated at the welding, joining the metal panel 110 and the step portion 121, and exhibits high strength even at high temperature in joining structural materials such as metal.

또한, 용접시 발생하는 용접액이 용접액 유입홀(141)로 유입되면서 단차부(121)와 금속패널(110)의 용접부위가 넓어짐에 따라 접합력이 더욱 향상된다.In addition, the welding force is further improved as the welded portion of the step portion 121 and the metal panel 110 becomes wider as the welding liquid generated during welding flows into the welding liquid inflow hole 141.

이와 같이 본 발명에 따른 차량용 히트 프로텍터 패널 제조방법은 2개의 판재를 금형롤러를 이용하여 상호 중첩하여 접합함은 물론 중첩되는 판재 사이에 공기층이 형성되도록 하여 차열 성능을 향상시킬 수 있을 뿐만 아니라, 제진 및 흡음 성능을 향상시킬 수 있게 된다.As described above, in the method of manufacturing a heat protector panel for a vehicle according to the present invention, not only the two plate materials are overlapped and joined together using a mold roller, but also an air layer is formed between the overlapping plate materials, And sound absorption performance can be improved.

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

따라서, 본 발명의 진정한 기술적 보호범위는 특허청구범위에 의해서 정하여져야 할 것이다.
