본 고안은 차량도어용 임펙트 바(impact bar)에 관한 것으로, 특히 충격흡수능력이 탁월한 차량도어용 임펙트 바에 관한 것이다.The present invention relates to an impact bar for a vehicle door, and more particularly to an impact bar for a vehicle door with excellent shock absorbing ability.
일반적으로 차량도어용 임펙트 바는 차량이 승용차의 경우 도어의 외장판과 내장판사이에 횡방향으로 착설되어 도어의 외부에서 가하여지는 충격을 최대한으로 흡수완화 시켜 운전자 또는 승객을 충격으로부터 보호하기 위하여 사용된다.In general, the impact bar for a vehicle door is used to protect the driver or passenger from impact by maximally absorbing and mitigating the impact from the outside of the door by installing the vehicle horizontally between the exterior and interior plates of the door in the case of a passenger car. .
종래 이러한 목적으로 차량도어내에 착설되는 임펙트 바는 단면형태가 원형이거나 사각형인 금속봉이 사용되었다. 그러나 이러한 금속봉형태의 임펙트 바는 재질 특성상 강도가 우수하여 내충격성은 있으나 이에 가하여지는 충격이 차량전체 또는 차량내부에 그대로 전달되어 탑승자에게 충돌충격이 전달될 수 있는 위험이 있다. 차량외부로부터 가하여지는 충격은 이것이 효과적으로 흡수완화되는 것이 탑승자 보호에 유리하다.Conventionally, the impact bar installed in the vehicle door for this purpose has been used a metal rod of circular or rectangular cross-sectional shape. However, such a metal bar-type impact bar has excellent strength in terms of material properties, and thus has impact resistance. However, the impact bar is transmitted as it is to the entire vehicle or the inside of the vehicle, and there is a risk that the impact shock may be transmitted to the occupant. The impact from the outside of the vehicle is advantageous for the occupant protection that it is effectively absorbed.
따라서, 본 고안에 있어서는 임펙트 바가 인장강도가 우수한 섬유강화열가소성 성수를 구성되고 내부에는 충격이 가하여지는 방향에 탄성이 우수한 보강사를 매입하여 타성보강토를 구성하므로서 외부충격을 크게 흡수화시킬 수 있도록 한 것이다.Therefore, in the present invention, the impact bar is composed of a fiber-reinforced thermoplastic water having excellent tensile strength and an elastic reinforcement is embedded in the direction in which an impact is applied to form an inertia reinforcement soil, thereby greatly absorbing external impact. will be.
본 고안에 있어서, 임펙트 바는 단면이 속이 비어있는 중공형의 사각형이거나 솔리드형의 프레임부재의 형태로 구성된다. 이 프레임부재를 구성하는 섬유강화열가소성수지로서는 섬유가 강화된 폴리 에틸렌 테레프탈레이트(PET)가 있으며 프레임부재내에 매입되는 보강사로서는 탄소섬유, 아라미드계장섬유, 티타늄강선 또는 강철선이 사용될 수 있다. 본 고안을 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention, the impact bar is configured in the form of a hollow rectangular or solid frame member with a hollow cross section. Fiber-reinforced thermoplastic resin constituting the frame member is a fiber-reinforced polyethylene terephthalate (PET), and carbon fiber, aramid-based fiber, titanium steel wire or steel wire may be used as the reinforcing yarn embedded in the frame member. Referring to the present invention in more detail based on the accompanying drawings as follows.
본 고안의 임펙트 바는 그 제 1실시형태에서 사각단면형태의 프레임부재(10)로 구성되고 제 2도와 제 3도에서 보인 바와 같이 차량도어의 외장판(12)과 내장판(14)사이에서 외장판(12)에 밀착되게 착설된다.The impact bar of the present invention is constituted by the frame member 10 of the rectangular cross section in the first embodiment and between the exterior plate 12 and the interior plate 14 of the vehicle door as shown in FIG. 2 and FIG. It is installed in close contact with the exterior plate 12.
이 프레임부재(10)는 이 프레임부재(10)의 양단이 삽입고정되는 C자형 고정부(16)를 가지고 프레임부재(10)에 대하여 수직으로 배치되어 외장판(12)과 내장판(14)사이에 협지고정되므로서 프레임부재(10)를 외장판(12)측으로 밀착 고정시키는 고정판(18)으로 구성되는 고정구(20)에 의하여 제 2도 및 제 3도에서 보인 바와 같이 고정된다.The frame member 10 has a C-shaped fixing portion 16 into which both ends of the frame member 10 are inserted and fixed, and is disposed perpendicularly to the frame member 10 so that the exterior plate 12 and the interior plate 14 are provided. It is fixed as shown in FIG. 2 and FIG. 3 by the fastener 20 which consists of the fixing plate 18 which clamps and fixes the frame member 10 to the exterior plate 12 side closely.
프레임부재(10)는 그 제 1실시형태에서 보인 바와 같이 단면이 속이 비어 있는 사각형(제 1도-제 3도 및 제 4도 a)이다. 이 제 1실시형태의 프레임부재(10)는 폴리 에틸렌 테레프탈레이트(PET)를 포함하는 고강도의 섬유강화 열가소성수지를 압출성형하여 얻으며 이 프레임부재(10)의 장변부측, 즉 외부충격에 대응하는 부분에 탄소섬유, 아라미트계장섬유, 티타늄강선 또는 강철선과 같이 인장강도가 우수한 섬유 보강사(22)가 매입된다.The frame member 10 is a rectangular cross section (FIGS. 1 to 3 and 4A) as shown in its first embodiment. The frame member 10 of the first embodiment is obtained by extrusion molding a high strength fiber-reinforced thermoplastic resin containing polyethylene terephthalate (PET), the long side of the frame member 10, i.e., a portion corresponding to an external impact. The fiber reinforcement yarns 22 having excellent tensile strength, such as carbon fibers, aramid-based fibers, titanium steel wires or steel wires, are embedded.
이와 같은 본 고안은 제 1실시형태의 이것이 차량도어에 착설되는 경우 프레임부재(10)의 재질특정상 충격흡수능력이 우수하고 탄성강도가 크게 강화되어 외부충격에 대하여 이를 효과적으로 흡수완화시키므로서 차량탑승자를 충격으로부터 효과적으로 보호할 수 있도록 한다.The present invention is a vehicle occupant of the first embodiment when it is installed on the vehicle door, the material member of the frame member 10 is excellent in the shock absorption ability and the elastic strength is greatly strengthened to effectively absorb and mitigate it against external impacts. To effectively protect against shock.
본 고안의 제 2실시형태(제 4도 a)에서는 프레임부재(10)가 그 단면형태가 사각솔리드형이며 보강사(22)가 사각단면의 장변부측에 매입되어 있다. 이 실시형태 역시 충격흡수능력이 우수할 것이다.In the second embodiment (Fig. 4A) of the present invention, the frame member 10 has a rectangular solid cross section, and the reinforcing yarn 22 is embedded on the long side portion of the rectangular cross section. This embodiment will also be excellent in shock absorbing capacity.
본 고안의 제 3실시형태(제 4도 c)는 프레임부재(10)가 다중사각형으로 채널내에 수개의 리브(24)가 배설되어 내충격성을 더욱 강화사킬 수 있도록 하였다.In the third embodiment of the present invention (FIG. 4C), the frame member 10 is multi-square in shape so that several ribs 24 are disposed in the channel to further enhance impact resistance.
이와 같이 본 고안은 인장강도가 우수한 보강사가 매입된 고강도의 섬유강화 열가소성수지를 재질로한 프레임부재로 구성되어 충격흡수능력이 우수한 차량용 임펙트 바를 제공한다.As such, the present invention is made of a frame member made of high-strength fiber-reinforced thermoplastic resin in which a reinforcement yarn having excellent tensile strength is embedded, thereby providing a vehicle impact bar having excellent impact absorption ability.
