[0002] At present, in the traditional automobile body assembling process, especially between automobile girders and front and rear crash beams, bolt and nut are usually used for connection and fixation. Pre-hanging structure is arranged between the girders and the front and rear crash beams. The pre-hanging structure usually adopts stud markers 1 formed by projection welding on the installation plate at the end of the girder. Pre-hanging holes 2 are arranged on the connecting plate formed at the end of the crash beam. When the crash beam is assembled between the two girders, the stud markers are inserted into the pre-hanging holes to complete the pre-hanging assembly.
[0003] As shown in Figure 1 and Figure 2 , the pre-hanging hole is designed as a waist hole structure and the size of the pre-hanging hole is larger than that of the stud marker. This structure does not have positioning effect on the crash beam. The structure has the following disadvantages: 1. A marker needs to be welded, which increases the cost of marker use, welding and welding fixture; 2. It is not convenient to complete pre-hanging operation.
[0004] Therefore, how to provide an automobile body assembling anti-drop pre-hanging structure with a more simple and reasonable structure design, which can reduce cost and make it easier to complete pre-hanging operation, has become a technical problem to be solved by technical personnel in the field.
