The invention provides a front cover inner plate and a tailor-welded boundary method thereof, which can reduce the weight of the front cover inner plate while ensuring necessary rigidity, and reduce the influence on the reduction of the pedestrian protection score. The front cover inner plate is formed by integrally stamping a laser tailor-welded blank, wherein the laser tailor-welded blank is formed by tailor-welding a plurality of tailor-welded components, and the adjacent tailor-welded components and the respective setting positions are made of different materials correspondingly and/or formed into different thicknesses. The front cover inner plate includes a pair of left and right hinge mounting tailor-welded members for mounting of the front cover hinge, and the distance between a first boundary, which is a boundary between the hinge mounting tailor-welded component and the adjacent tailor-welded component, and the center of a mounting part to which the front cover hinge is mounted with respect to the hinge mounting tailor-welded component is 30mm or more.
本发明提供一种前盖内板及其拼焊分界方法,能够在确保必要刚度的同时减轻前盖内板的重量,并减少对行人保护分值的降低影响。前盖内板由激光拼焊板一体冲压而构成,激光拼焊板通过对多个拼焊部件进行激光拼焊而形成,相邻的拼焊部件与各自的设置位置相应地采用不同的材料及/或形成为不同的厚度,前盖内板包括供前盖铰链安装的左右一对的铰链安装拼焊部件,铰链安装拼焊部件与相邻的拼焊部件的分界线即第一分界线、和前盖铰链相对于铰链安装拼焊部件安装的安装部的中心之间的距离为30mm以上。
