Abstract

PURPOSE: A center floor assembly of a vehicle is provided to improve rigidity of a vehicle body and to minimize vibration and booming noise by adding a reinforcing member to a lower surface of a center floor panel introduced with a cross member on an upper surface. CONSTITUTION: A center floor assembly of a vehicle has a reinforcing cross member(100) additionally. The reinforcing cross member is introduced to a lower surface of a center floor panel(10) introduced with a cross member(20) with an upper portion open. The reinforcing cross member is welded to the center floor panel to be contacted to the center floor panel with folded joint surfaces(110) of both ends. Therein, one end of the reinforcing cross member is jointed to the center floor panel and the other end is fixed to a mounting bracket member fixed to a frame side member. Consequently, rigidity of a vehicle body is improved and vibration and noise are prevented by fixing the lower surface of the center floor panel to the other frame of the vehicle body together with the cross member.

차량의 센터 플로어 조립체{Assembly for a center floor of a vehicle}Assembly for a center floor of a vehicle

본 발명은 차량의 센터 플로어 조립체에 관한 것으로, 특히 상측 면에 횡방향으로 크로스멤버가 취부되는 센터 플로어 패널의 저면에 보강부재를 추가하여 차체의 강성을 향상시키며, 차량 진동과 노이즈의 발생을 최소화할 수 있는 센터 플로어 조립체에 관한 것이다.The present invention relates to a center floor assembly of a vehicle. In particular, a reinforcing member is added to a bottom surface of a center floor panel in which crossmembers are mounted on the upper surface to improve the rigidity of the vehicle body and minimize the occurrence of vehicle vibration and noise. The center floor assembly which can be.

일반적으로 차량의 승객이 느끼는 소음, 진동 및 차량의 요동 등에 의한 승차감은 최종적으로 차체로 전달된 특성에 의해 결정되며, 샤시 프레임 형식의 차량에서 차체의 이와 같은 특성은 프레임과 차체를 연결시키는 바디 마운팅 구조를 통하여 최종적으로 전달되며, 이때 차체의 바디 마운팅 주변부의 구조 및 강도, 강성은 매우 중요하게 된다.In general, the ride comfort caused by noise, vibration and fluctuations of the vehicle's passengers is determined by the characteristics finally delivered to the vehicle body. In a chassis frame type vehicle, such characteristics of the vehicle body are the body mountings connecting the frame and the vehicle body. Finally delivered through the structure, the structure, strength, and rigidity of the body mounting periphery of the vehicle body becomes very important.

따라서, 바디 마운팅 주변의 사양은 다른 부위에 비하여 보다 높은 강도를 만족할 수 있는 재질 및 두께를 선택해야 하며, 주변과 최대한 고정될 수 있는 구조를 갖도록 하는 것이 바람직하다.Therefore, the specification around the body mounting should select a material and thickness that can satisfy the higher strength than other parts, it is desirable to have a structure that can be fixed as possible with the surroundings.

도 1 및 도 2는 종래의 차량 센터 플로어의 구조에 관한 것으로, 도 1은 크로스멤버가 취부된 차량의 플로어 패널을 보여주는 도면이며, 도 2는 도 1의 A-A' 선의 단면도이다.1 and 2 are related to the structure of a conventional vehicle center floor, FIG. 1 is a view showing a floor panel of a vehicle on which crossmembers are mounted, and FIG. 2 is a cross-sectional view taken along line AA ′ of FIG.
