Embodiment 1

[0031] Such as figure 2 As shown, the hair cover hinge 1 of the present invention includes a hinge upper blade 2 and a hinge lower blade 3 connected by a pin shaft 14, the hinge upper blade 2 and the hinge lower blade 3 are all integrally cast, and the hinge upper blade 2 is fixed on the hair On the inner panel of the cover and the reinforcement plate of the inner panel, the lower blade 3 of the hinge is fixed on the main body of the reinforcement board on the front wheel house. Surface 7; the middle section 5 is bent obliquely to the right from the end of the front section 4, and at the same time it is bent into a V shape with the rear section 6. The cross section of the middle section 5 is a transverse U shape; the cross section of the rear section 6 is formed by a transverse U The shape gradually transitions to an L shape; the cross section of the blade 3 under the hinge is an L shape.

[0032] Such as image 3 , 4 , 5, the height of the middle section 5 and the rear se...

Abstract

The invention provides a hair cover hinge structure. The hair cover hinge structure comprises an upper hinge blade and a lower hinge blade which are connected through a pin shaft, wherein the upper hinge blade is fixed to a hair cover inner plate and an inner plate reinforcing plate, the lower hinge blade is fixed to an upper reinforcing plate body of a front wheel cover, the upper hinge blade isof a three-section bent structure, and the front section is an installation surface provided with a turned edge; the middle section is bent slantwise and towards the lower right part from the tail endof the front section, and bent to form a V-shape with the rear section simultaneously, and the cross section of the middle section is in a transversal U-shape; the cross section of the rear section is in a transversal U-shape or gradually transited from the transversal U-shape to an L-shape; and the cross section of the lower hinge blade is in an L-shape. According to the hair cover hinge structure, the upper hinge blade is designed to be of the three-section bent structure, and section optimization is carried out, so that crushing and energy absorption space in a head impact process are increased; and the hinge is capable of generating stable gradual deformation in an extrusion direction to achieve an energy absorption effect, so that the pedestrian protection certification regulation requirements are met.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a hair cover hinge structure which is beneficial to pedestrian head protection. Background technique [0002] With the widespread popularization of family cars in our country, the problem of road pedestrian safety has become more and more prominent. Because pedestrians are directly exposed to various traffic environments, they often suffer the most serious injuries in automobile traffic accidents, and the death rate of pedestrians is 9 times that of drivers and passengers. Among the global road traffic accidents in 2015, the number of pedestrian deaths in road traffic accidents in China accounted for the highest in the world, accounting for 30% of the total. For the above reasons, enhanced safety measures to protect vulnerable pedestrians have been included as standard requirements for car manufacturers in every important global market. At present, the European ...
