Self-supporting structure for internal combustion engine used in vehicle e.g. machine-operated electro motor vehicle, has transverse wall portion which is extended with respect to roof area in vehicle longitudinal direction

摘要

#CMT# #/CMT# The supporting structure (1) has an intermediate layer (5) which is formed between the plastic inner and outer casings (2,3). A main base (6) formed between a front-end region (9) and a rear-end region (11) along the vehicle longitudinal direction is extended with respect to plastic inner casing. A transverse wall portion (20) formed over the entire width of vehicle is extended with respect to a roof area (19) in vehicle longitudinal direction. The intermediate layer is made of foam material. #CMT#USE : #/CMT# Self-supporting structure e.g. trough-shaped structure such as window and door for internal combustion engine used in vehicle e.g. machine-operated electro motor vehicle such as car. #CMT#ADVANTAGE : #/CMT# The rigidity and stiffness of the self-supporting structure can be improved. The working efficiency can be improved. The self-supporting structure can be manufactured easily. The weight of the self-supporting structure can be reduced. The manufacturing cost of the self-supporting structure can be reduced. The design of the self-supporting structure can be simplified. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the sectional views of the self-supporting structure. 1 : Self-supporting structure 2 : Plastic inner casing 3 : Plastic outer casing 6 : Main base 9 : Front-end region 11 : Rear-end region 19 : Roof area 20 : Transverse wall portion.
