In order to promote the rigidity of the trunk lid assembly, also in order to promote the rigidity of running through formula tail lamp mounting panel simultaneously, generally can increase the support in the both sides of running through formula tail lamp mounting panel and support, the intermediate position design turn-ups structure of inner panel makes it overlap joint with running through formula tail lamp mounting panel and adopts the inflation to glue further to connect to promote the rigidity of running through formula tail lamp mounting panel simultaneously. However, because the expansion glue is adopted for connection, the situation that the expansion glue is lack or the expansion glue is not firmly adhered is unavoidable, so that the rigidity of the penetrating type tail lamp mounting plate is affected, abnormal sound is possibly generated, and the quality of an automobile is affected. If the connection is performed without using the expansion glue, the support provided by the flanging structure or the support leg on the inner plate to the through-type tail lamp mounting plate is limited, and in order to improve the support strength of the flanging structure or the support leg to the through-type tail lamp mounting plate, the whole structure of the inner plate is often required to be redesigned and improved so that the flanging structure or the support leg has a better angle and/or length relative to the through-type tail lamp mounting plate; however, this causes trouble in designing and producing the inner panel and reduces the overall rigidity of the trunk lid.
