When the door impact beam of the vehicle is installed in a door frame, the door impact beam comprises a linear unit, a round type reinforcing rib connection unit, and a bent unit in order to correspond to impact directions applied from the outside of a door. A protrusion unit is formed in the mounting reinforcement unit having a reinforcing function to be able to apply elasticity when the bolt is connected. According to the present invention, the support bar and the mounting reinforcement unit comprising the door impact beam are a one-piece structure so that the present invention can improve productivity and reduce manufacture costs. The shape of the support bar is a structure in which the durability about bending is improved so that the support bar can restrict the door towards the inside in a side collision and safely protect a passenger. The mounting reinforcement unit can prevent the bolt from being loosen as an uneven part performs the elasticity when connected to the door frame by the bolt. The mounting reinforcement unit also improves quality of the door impact beam by maintaining a stable mounting state.

Description

내구성과 체결력 강화구조를 갖는 자동차의 도어 임팩트 빔{Automotive door impact beam that have durability and conclusion power strengthening structure}Automotive door impact beam that have durability and conclusion power strengthening structure}

본 발명은 내구성과 체결력 강화구조를 갖는 자동차의 도어 임팩트 빔에 관한 것으로서, 더욱 상세하게는 도어 임팩트 빔을 구성시 우수한 내구성이 강화될 수 있게 지지바가 구성되고, 마운팅 레인포스먼트는 볼트 체결시 풀림이 방지될 수 있도록 구성된 자동차의 도어 임팩트 빔에 관한 것이다.The present invention relates to a door impact beam of a vehicle having a durability and tightening force reinforcing structure, and more specifically, the support bar is configured to be excellent durability when configuring the door impact beam, the mounting reinforcement is loosened when the bolt is fastened This relates to a door impact beam of a motor vehicle configured to be prevented.

일반적으로 자동차 충돌의 유형을 살펴보면, 정면충돌, 측면충돌, 후면충돌 등 여러 유형이 있다.In general, when looking at the types of car crashes, there are several types of collisions, such as frontal collisions, side collisions, and rear collisions.

특히, 측면 충돌시에는 도어로부터 탑승자의 안전을 확보할 수 있는 안전공간이 좁기 때문에 공간이 충분한 정면충돌과 후면충돌에 비해서 탑승자의 안전이 매우 취약하다.In particular, in the event of a side collision, the safety space for securing the occupant's safety from the door is narrow, so that the occupant's safety is very weak compared to a sufficient front and rear collision.

따라서, 자동차 메이커에서는 자동차의 도어 내부에 일정한 강성을 가진 도어 임팩트 빔을 장착시켜 측면 충돌시 자동차 도어가 실내로 밀려들어가는 양을 줄여서 탑승자에게 전달되는 충격을 완화시킬 수 있도록 하고 있다.Therefore, the car maker is equipped with a door impact beam having a certain rigidity inside the door of the car to reduce the amount of the car door is pushed into the room during side impacts to mitigate the shock delivered to the occupant.

상기와 같은 자동차의 도어 임팩트 빔은 충돌시 직접적인 대응력을 받을 수 있도록 도어를 횡단하는 지지바와, 상기 지지바를 도어 프레임에 고정하기 위하여 지지바의 양측단부에 마운팅 레인포스먼트가 구성되어 있다.The door impact beam of the vehicle includes a support bar crossing the door so as to receive a direct response force in a collision, and mounting reinforcement at both ends of the support bar to fix the support bar to the door frame.

종래 상기와 같은 도어 임팩트 빔은, 내구성이 보강되고 생산성이 향상될 수 있는 도어 임팩트 빔을 개발하는데 많은 노력을 하고 있으며, 대표적인 도어 임팩트 빔에 구성을 살펴보면, 임팩트 빔을 구성하는 지지바는 대부분 환봉으로 구성되어 있고, 상기 지지바의 양측에 마운팅 레인포스먼트가 용접으로 연결되어 구성된다.Conventionally, the door impact beam as described above, has made a lot of efforts to develop a door impact beam that can be enhanced in durability and productivity, and looking at the configuration of the typical door impact beam, the support bar constituting the impact beam is mostly round bar Consists of, the mounting reinforcement on both sides of the support bar is configured by welding.

상기와 같이 구성된 도어 임팩트 빔은 조관된 환봉으로 구성된 지지바의 양측에 마운팅 레인포스먼트가 용접에 의해서 일체로 구성되기 때문에 용접부의 산화작용으로 인하여 도어 임팩트 빔의 강성이 점점 저하되는 단점이 있다.The door impact beam configured as described above has a disadvantage in that the rigidity of the door impact beam is gradually decreased due to oxidation of the welding part because the mounting reinforcement is integrally formed by welding on both sides of the support bar constituted by the pipe rod.

또한, 지지바의 양측에 마운팅 레인포스먼트가 겹쳐지는 구성이기 때문에 소재가 많이 소요됨은 물론이고, 그로 인하여 도어 임팩트 빔의 무게가 무거워지게 되므로 차동차 경량화에 역행하게 되는 단점이 있다.In addition, since the mounting reinforcement is overlapped on both sides of the support bar, it takes a lot of material, and as a result, the weight of the door impact beam becomes heavy, and thus, there is a disadvantage in that the weight of the differential vehicle is reversed.

그리고, 상기한 도어 임팩트 빔을 구성하는 2개의 마운팅 레인포스먼트는 금속판재를 절단, 절곡, 펀칭 등의 단계를 거쳐 완성한 후, 조관 공정으로 제조된 지지바의 양측에 겹쳐서 용접하는 구성으로서, 다공정에 의한 생산성 저하와 도어 임팩트 빔의 제조원가를 상승시키는 단점이 있다.In addition, the two mounting reinforcement constituting the door impact beam is a configuration in which the metal plate is finished through cutting, bending, punching, and the like, and then overlapped and welded on both sides of the support bar manufactured by the tubing process. There is a disadvantage in that the productivity decreases due to the process and increases the manufacturing cost of the door impact beam.

상기한 바와 같이 지지바의 양측에 마운팅 레인포스먼트가 겹쳐지는 구성으로 임팩트 빔의 무게가 무거워지는 단점을 해결하기 위하여 최근에는 금속판재를 도어 임팩트 빔을 구성하는 지지바와 양측에 마운팅 레인포스먼트를 연결한 상태의 형상으로 금속판재를 블랭킹한 후, 지지바(100)를 조관하고, 상호 닿는 연결편(101) 부분은 도 1에서 보는 바와 같이 아크용접에 의해서 단일체가 되도록 구성하며, 상기와 같이 구성된 지지바의 양측에 마운팅 레인포스먼트(102)가 일체로 구성되게 한 것이 있다.As described above, in order to solve the disadvantage that the impact beam becomes heavy due to the overlapping mounting reinforcement on both sides of the support bar, recently, a metal plate is mounted on both sides of the support bar constituting the door impact beam. After blanking the sheet metal in the shape of the connected state, the support bar 100 is piped, and the connecting pieces 101 are in contact with each other, as shown in Figure 1 configured to be a single body by arc welding, configured as described above The mounting reinforcement 102 is integrally formed on both sides of the support bar.

그런데, 조관된 지지바(100)를 구성하는 보강리브가 외부에 하중이 가해지면 쉽게 절곡되는 위치에 형성되어 있고, 지지바를 관체형으로 연결하기 위하여 형성된 절곡편을 서로 밀착하여 도 1에서 보는 바와 같이 접지면의 외부만 아크용접되어 있기 때문에 외부 충격이 기해지면 절곡편이 벌어지는 결과로 내구성이 떨어지는 단점이 있다.By the way, the reinforcing rib constituting the support bar 100 is formed in a position that is easily bent when a load is applied to the outside, the bending pieces formed to connect the support bar in a tubular shape close to each other as shown in Figure 1 Since only the outside of the ground plane is arc welded, there is a disadvantage in that durability is reduced as a result of the bending piece opening when the external impact is exerted.

그리고, 마운팅 레인포스먼트에 형성된 볼트공의 주변이 평탄하게 형성되어 있기 때문에 임팩트 빔을 도어 프레임에 장착하기 위해 볼트공을 통해 체결된 볼트가 쉽게 풀어지는 등 구조적으로 많은 문제가 있다.In addition, since the periphery of the bolt hole formed in the mounting reinforcement is formed flat, there are many structural problems such as the bolt fastened through the bolt hole for easy mounting of the impact beam to the door frame.

상기한 문제점을 해결하기 위한 본 발명은 도어 임팩트 빔을 구성하는 지지바와 마운팅 레인포스먼트를 일체형으로 구성하여 작업성을 향상시키는 동시에 지지바를 구성시 원형관체와 사각관체의 장점을 취하여 내구성을 증가시킬 수 있게 하며,The present invention for solving the above problems to improve the workability by configuring the support bar and the mounting reinforcement constituting the door impact beam to improve the workability at the same time to take advantage of the round tube and square tube when constructing the support bar to increase the durability To make it possible,

또한, 마운팅 레인포스먼트를 볼트로 체결시 볼트가 풀어지는 것을 방지할 수 있도록 구성된 내구성과 체결력 강화구조를 갖는 자동차의 도어 임팩트 빔을 제공함에 그 목적이 있다.In addition, an object of the present invention is to provide a door impact beam of a vehicle having a durability and fastening force reinforcing structure configured to prevent the bolt from loosening when the mounting reinforcement is bolted.

본 발명에 의한 내구성과 체결력 강화구조를 갖는 자동차의 도어 임팩트 빔을 구성시, 자동차의 도어 임팩트 빔을 도어 프레임에 설치하였을 때 도어 외측으로부터 받는 충격방향에 대응되도록 직선부와 보강리브 라운드형 연결부, 절곡편으로 구성되며,When constructing a door impact beam of a vehicle having durability and fastening force reinforcing structure according to the present invention, when the door impact beam of the vehicle is installed in the door frame, the straight portion and the reinforcement rib round connection part to correspond to the impact direction received from the outside of the door, Consists of bending pieces,

또한, 도어 임팩트 빔을 구성하는 마운팅 레인포스먼트에는 보강기능과 함께 볼트체결시 탄성을 부여할 수 있게 돌출부가 형성되어 구성된 것이 본 발명에 특징이다.In addition, the mounting reinforcement constituting the door impact beam is characterized in that the protrusion is formed so as to provide elasticity when tightening the bolt together with the reinforcing function.

상기와 같은 본 발명에 의하면, 도어 임팩트 빔을 구성하는 지지바와 마운팅 레인포스먼트가 원피스 구조이기 때문에 생산성 향상 및 제조원가 절감할 수 있는 효과가 있으며,According to the present invention as described above, since the support bar and the mounting reinforcement constituting the door impact beam has a one-piece structure, there is an effect of improving productivity and reducing manufacturing costs,

또, 지지바의 형상이 밴딩에 대한 내구성이 향상되는 구조이기 때문에 측면충돌시 도어가 실내로 들어오는 것을 최대한 억제시킬 수 있어 탑승자를 안전하게 보호할 수 있는 효과가 있으며,In addition, since the shape of the support bar improves the durability of the banding, it is possible to restrain the door from entering the room as much as possible in the event of a side collision, thereby protecting the occupants safely.

또한, 마운팅 레인포스먼트를 도어 프레임에 볼트로 체결하였을 때 요철부가 탄성작용을 하여 볼트가 풀어지는 것을 방지하고, 견고한 장착상태를 유지함으로써 도어 임팩트 빔의 품질을 향상시키는 효과가 있다.Further, when the mounting reinforcement is bolted to the door frame, the uneven portion elastically prevents the bolt from loosening and maintains a firm mounting state, thereby improving the quality of the door impact beam.
