Door seal structure and the corresponding structural Analysis

After years of development, automotive power were gradually formed their own technical characteristics and process on the basis that they are designed and manufactured products have their own characteristics and differences. As the body can best reflect the personality of the design features to better reflect this difference, particularly the design of the door structure, we can find a good variety in form and the manufacturing process of the door structure is different. After a large number of the current market, some mainstream sedan body structure analysis, summarized typical car door sheet metal structure and the corresponding door sealing (printed cable ties)system.
Door sheet metal structure and composition of the door sealing system
Door sheet metal is the most important part of the inner door panel and car door panels, they will form a closed cavity, we usually windowsill above part is called the window frames, window frames with sealing strips for fixed door glass and the guide glass lifts, window sills below the cavity can be arranged several reinforcing beams, stiffeners and some functional accessories, such as window regulator, door locks and glass.

Door seal system is mainly for two areas, one area is sealed doorway, which rely mainly installed in the side of the flange openings around a circle on the side door seal mounted on the door or the door seal to the outer circle Seal the entire doorway. Some models have a seal laps, some with only a lap seal, different models depending on the performance requirements or cost objectives to select in what sealed policies. Another door is a door area to be sealed area, which rely mainly on the window frame and glass run channel seal seals the inner and outer window to implement two meter seals  but also they serve to window glass can be smoothly up and down elevating the role, usually glass run channel seal is the most demanding vehicle sealing systems, the structure of the most complex.
