Abstract

A blow-molded door inside member for car formed of thermoplastic resin and having a door intermediate panel and a door trim formed integrally with each other, wherein the door intermediate panel has a functional part mounting function and also can have a shock absorbing part, and the shock absorbing part forms a plurality of recessed parts, whereby the door inside member can be reduced in weight, can be simplified in structure, can withstand side collision, can increase productivity, can remarkably reduce the number of parts, can save a labor even in the door assembly process, and can increase recycling capability.

Description

technical field [0001] The present invention relates to an automotive door inner part constituting the interior side of a door glass of an automobile door. Background technique [0002] In recent years, in order to improve the collision safety of automobiles, measures such as strengthening the body and installing airbag devices have been taken. In addition, from the perspective of resource saving and environmental protection, how to reduce fuel consumption has become the most important issue. In order to solve these problems, it is urgent to realize the reduction of vehicle weight. For the purpose of reducing the weight of automobiles, the transition from metal to resin for various parts is in progress. For these auto parts, in addition to considering the formability, strength, rigidity, etc., from the perspective of trends such as recyclability and material unification, from the existing fiber-reinforced thermosetting resin (FRP) to thermoplastics such as polypropylene res...
