Abstract

PURPOSE: Frame reinforcing structure is provided to improve reliability and protect passengers safely in a vehicle room by restricting bending deformation of a frame with installing a reinforcing member including upper and lower plates in the bent portion of the frame at a collision. CONSTITUTION: A frame(10) is combined with a chassis and engine parts of a vehicle to increase the rigidity of the vehicle body. A reinforcing member(20) is composed of a lower plate(21) below the frame welding into a bent portion(11) of a frame and having an assembling part(211) bent, and an upper plate(22) placed at the side of the frame, and fixed by welding the bent portion of the frame into combination parts(221) bent in upper and side parts and welding the assembling part into the combination part in the lower part. Safety of the passenger is improved with restricting deformation of the bent portion of the frame at a collision with mounting the reinforcing member in the bent portion of the frame.

Description

프레임 보강구조{Frame reinforcement}Frame reinforcement}

본 발명은, 프레임 보강구조에 관한 것으로 더욱 상세하게는 프레임의 절곡부에 보강부재를 추가함으로써 차량의 정면충돌시에 프레임의 급격한 변형을 방지하여 탑승자의 안전성을 향상시킨 것이다.The present invention relates to a frame reinforcing structure, and more particularly, by adding a reinforcing member to the bent portion of the frame to prevent sudden deformation of the frame during a frontal collision of the vehicle, thereby improving occupant safety.

도 1은 종래 프레임의 구성 형상을 도시한 정면도이며, 도 2는 상기 도 1에서 도시한 A-A 단면을 확대한 측면도이다.1 is a front view showing a configuration of a conventional frame, Figure 2 is an enlarged side view of the A-A cross-sectional view shown in FIG.

통상적인 프레임(10)은 플로어 하단 양측에 대칭으로 용접되며, 이중절곡된 형상으로 차체의 강성 및 충돌시 탑승자의 안전에 중요한 역할을 하게된다.The conventional frame 10 is symmetrically welded to both sides of the bottom of the floor, and a double bent shape plays an important role in the rigidity of the vehicle body and the safety of the occupant in the event of a crash.

또, 각종 샤시,엔진계 부품이 상기 프레임(10)에 취부됨으로써 국부적인 강성도 요구되고 있다.In addition, local stiffness is also required by mounting various chassis and engine components to the frame 10.

상기 프레임(10)은 차량에 따라, 프런트 프레임과 센터 프레임의 부품으로 구성되고, 프런트 프레임, 센터 프레임, 리어 프레임의 세부품으로도 구성되나 생산성 측면의 분활일 뿐 요구되는 목적은 상기의 차체강성 및 충돌시 탑승자의 안전성에 있어서 동일하다.The frame 10 is composed of parts of the front frame and the center frame according to the vehicle, and is composed of the details of the front frame, the center frame, and the rear frame, but is a division in terms of productivity. And the safety of the occupant in the event of a crash.

그러나 상기 프레임은 차량주행 중 특히 승합차의 경우 정면충돌시 프레임에서 거의 모든 충돌에너지를 흡수할 수 있도록 설계되어야 한다.However, the frame should be designed to absorb almost all collision energy in the frame during frontal collision, especially in the case of a van.

따라서, 충돌에너지를 흡수하는 가장바람직한 프레임구조는 절곡이 없는 직선 구조이어야 한다.Therefore, the most desirable frame structure for absorbing collision energy should be a straight structure without bending.

그러나, 상기 프레임으로는 엔진의 취부, 트렌스미션의 장착, 거주공간의 확보등에 의해 절곡이 없는 직선구조로 프레임을 설정하기란 거의 불가능하다However, it is almost impossible to set the frame in a straight structure without bending due to the installation of the engine, the installation of the transmission, the securing of the living space, and the like.

즉, 도 1에서 도시한 A-A 부위는 절곡이 심하여 차량충돌시 충돌에너지가 집중돼 급격한 변형이 이루어지게 된다.That is, the A-A portion shown in FIG. 1 is severely bent, so that collision energy is concentrated when the vehicle crashes, resulting in rapid deformation.

따라서, 차량 설계시 유도했던 프레임의 점진적 변형에 의한 에너지 감쇠효과가 이루어지지않고 승객실로 충격에너지가 그대로 전달되어 차량내부의 탑승객의 안전을 보장하여 주지 못하였다.Therefore, the energy attenuation effect due to the gradual deformation of the frame induced during the design of the vehicle is not achieved, and the impact energy is transferred to the passenger compartment as it is, thereby preventing the safety of passengers inside the vehicle.

본 발명의 목적은, 상기 프레임의 절곡부위에 보강부재를 설치하여 차량충돌시 발생되는 변형을 억제하도록 하여, 차량내부의 탑승객의 안전성을 향상시키도록 한 프레임 보강구조에 관한 것이다.An object of the present invention relates to a frame reinforcement structure in which a reinforcement member is installed at a bent portion of the frame to suppress deformation generated during a vehicle crash, thereby improving safety of passengers inside the vehicle.
