Front bonnet structure for motor vehicle, has effort absorbing unit arranged in hollow body between bottom and upper part of body, where bottom and upper part are formed by inner surfaces of inner panel and bonnet skin, respectively

摘要

#CMT# #/CMT# The structure has an effort absorbing unit (50) arranged in a hollow body (40) between bottom and an upper part of the body. The bottom of the body is formed by an inner surface of an inner panel (20) of a bonnet (1), and the upper part of the body is formed by an inner surface of a bonnet skin (10). The inner panel is disposed below the bonnet skin and arranged such that the body is formed between a part of the bonnet skin and a part of the inner panel. The effort absorbing unit presents a shape of a space bar perpendicular to the bottom of the body. #CMT#USE : #/CMT# Front bonnet structure for a motor vehicle. #CMT#ADVANTAGE : #/CMT# The structure absorbs a pedestrian impact on the bonnet and before contacting the structure with incompressible hard spots such as power train, in an inexpensive, reduced encumbrance and effective manner. The effort absorbing unit is arranged in the hollow body between the bottom and the upper part of hollow body, thus allowing elastic deformations of the skin and strengthening of the hollow body by the effort absorbing unit at center of the hollow body in order to avoid measling of the bonnet. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a front bonnet structure before a pedestrian impact. 1 : Bonnet 10 : Bonnet skin 20 : Inner panel 40 : Hollow body 50 : Effort absorbing unit.
