The structure and design development of the door hinge_Hinge knowledge_Tallsen 1

As an integral part linking the body and the door, the door hinge plays a crucial role in ensuring the proper functioning of the door and maintaining its position relative to the body. Its main function is to facilitate the smooth opening and closing of the door. However, in addition to its functional role, the design of the hinge also needs to take into account other factors such as ergonomics, styling seams, and prevention of door sagging.

The general design and development process of door hinges involves several steps. Firstly, the hinge form needs to be determined. There are two main types of hinges - open hinges and concealed hinges. Concealed hinges are more commonly used and can be inward or outward opening. The structure of the hinge can vary, including stamping type, welding type, fixed type, and integral type.

The fixed form of the door hinge involves three main connection methods: it can be connected with the body and the side wall using bolts, welded with the door and bolted with the side wall, or connected with the door and side wall through welding.

Several parameters need to be considered when designing a door hinge. These include the camber angle inside the body, front and rear inclination angles of the door, maximum opening angle of the hinge, maximum opening value of the car door, and the distance between the center of the upper and lower door hinges. These parameters are important for ensuring proper door movement and preventing interference with other parts of the body.

During the design process, motion interference checks need to be conducted to ensure that the door does not interfere with any part of the body during the opening and closing process. This includes determining the minimum gap between the body and the door at various angles of door movement.

The optimization of the door hinge axis is also crucial. This involves determining the position of the hinge based on the outer shape and parting line of the door. Factors such as hinge distance, maximum opening angle, and layout relationship between the hinge and the surrounding area need to be considered to ensure proper door movement and prevent sagging.

Once the preliminary layout of the hinges is determined, the detailed structure of the hinge can be designed. This includes determining the number of parts, material, material thickness, and size of each component. CAE analysis, strength and durability checks, and feasibility discussions with suppliers are also important in the hinge design process.

In summary, the design of door hinges is a crucial aspect of ensuring proper functionality and ergonomics of the door. It involves determining the hinge form, fixed form, hinge axis parameters, and conducting motion interference and feasibility checks. The detailed structure of the hinge is then designed, taking into account material, thickness, and size considerations. Careful consideration and comprehensive analysis is necessary to ensure the success of the hinge design.
