Problems solved by technology

However, the shock absorbing performance of the existing shock absorber 5 is as follows: Figure 54 As shown in the graph shown, the amount of deformation stroke (stroke) by which the side wall 5c of the shock absorber 5 is deflected increases linearly almost in proportion to the reaction force, and in particular, due to the reaction force in the second half stage when the shock load occurs, become larger, so it is imperative to reduce the reaction force in the second half of the impact load

Abstract

The invention discloses an in-built component for an automobile. The in-built component for the automobile is provided with an impact absorbing body arranged at the inner side of the side panel chamber of the automobile, and can enhance the impact absorbing performance by improving the shape and the structure of the impact absorbing body capable of absorbing impact load on the basis of bending deflection when side impact occurs. One side of the impact absorbing body (30) at the back side of an impact area (IA) of the in-built component for the automobile (10), i.e. a door panel, is provided with an opening (31), and the other side of the impact absorbing body (30) is provided with a hollow box body with a bottom wall (32); and the four corners of the bottom wall (32) are provided with corner cutting parts (34), chamfering is carried out on the turning parts of a side wall (33) to form chamfer parts (333) and form slot parts (334) for occlusion or triangular fins (36) or inner fin (321) and the like, thus regulating the reacting force when side impact occurs and further improving the impact absorbing performance.

Description

technical field [0001] The present invention relates to an automotive interior part installed on the interior side of a vehicle side panel, such as a door trim panel and a rear side trim panel, and particularly relates to improving the energy absorption performance and reducing the energy applied to the occupant when the vehicle collides with the side. Loaded automotive interior parts. Background technique [0002] In general, various automotive interior parts are attached to the vehicle interior, and a typical automotive interior part includes an automotive door trim attached to a side panel of a vehicle. [0003] refer to Figure 51 and Figure 52 The structure of the door trim panel for an automobile will be described with reference to a front view of the door trim panel and a cross-sectional view of the door trim panel for an automobile. As shown in the figure, the door trim panel 1 for an automobile protrudes toward the interior, and the armrest 1a is also formed to p...
