Type.When vehicle and pedestrian collision, impact force can be passed to the connector 3 by the hood by the swing arm 1,
When the impact force exceedes predetermined value, the deformation of separation structure 5 is to causing the connector 3 to pass through the separation structure 5, very
It is broken to being impacted.Wherein, the dimensional parameters of the Part I and the Part II（Such as length, width and thickness）Can
Selected by way of experiment, the dimensional parameters of selection, which will enable, makes the separation structure 5 when impact force reaches preset value
Deformation extremely causes the connector 3 to pass through the separation structure 5, or even is impacted and is broken, so that the edge of the connector 3
The crumple of second hole portion 413 simultaneously extrudes the spring 6.
In the above-described embodiments, the separation structure 5 can also be connected in which can be broken with the inwall of the through hole 41, also
It is to say, the Part I 51 is connected in which can be broken with first installation portion 43, the Part II 53 and the described second peace
Dress portion 45 connects in which can be broken.When the power that the connector 3 is applied to the separation structure 5 exceedes predetermined value, the separation
Structure 5 can depart from the inwall of the through hole 41.
The one embodiment that can also be connected with being broken with the inwall of the through hole 41 as the separation structure 5, institute
Separation structure 5 is stated to be connected with being broken by electric resistance welding with the inwall of the through hole 41.The welding parameter of electric resistance welding（Such as weld pressure
Power, time, voltage, electric current and electrode size）It can be selected by way of experiment, the welding parameter of selection will to work as impact force
The separation structure 5 can be made to depart from the inwall of the through hole 41 when reaching preset value, so that the connector 3 is along described
The crumple of second hole portion 413 simultaneously extrudes the spring 6.
It should be noted that the preset value in above-mentioned is selected according to pedestrian head injury values.
The automotive hinge structure and the automobile using the automotive hinge structure that above-described embodiment provides, at least with following skill
Art effect：When vehicle and pedestrian collision, impact force can be passed to the company by the hood by the swing arm 1
Fitting 3, when the impact force exceedes predetermined value, the separation structure 5 is destroyed and fails, so as to which the connector 3 can be along institute
State the crumple of the second hole portion 413 and extrude the spring 6.Due to the cushioning effect of the spring 6, collision process can be caused more
Gently, so as to effectively reduce the injury suffered by pedestrian head, in the case of especially less in crumple space；Together
When, only need to change mounting blocks because the mounting blocks 4 and the upper pedestal 21 are detachably connected, during maintenance, consequently facilitating dimension
Repair and reduce maintenance cost；In addition, again because the Part I 51 is fixedly arranged on first installation portion 43, described second
53 are divided to be fixedly arranged on second installation portion 45, so as to be easy to the processing and manufacturing of the separation structure 5.
More than, only it is presently preferred embodiments of the present invention, any formal limitation not is made to the present invention, although this
Invention is disclosed above with preferred embodiment, but is not limited to the present invention, any person skilled in the art,
Do not depart from the range of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent
The equivalent embodiment of change, as long as being without departing from technical solution of the present invention content, the technical spirit according to the present invention is real to more than
Any simple modification, equivalent change and modification that example is made is applied, in the range of still falling within technical solution of the present invention.
