Description
Technical field
The utility model belongs to auto Body Technology field, is specifically related to the hinge strengthening structure of automobile.
Background technology
Car bra is connected with vehicle body by steel hinge, due to higher to the requirement of strength of front hood hinge attachment point, be generally all designed with herein the hinge reinforcement of steel plate punched moulding, hinge reinforcement is welded on front hood back head, on it, be welded with nut, by bolt and steel chain connection.Along with the development of automotive light weight technology, for realizing lightweight, the front shroud inner and outer plates of some automobiles has progressively adopted aluminum alloy materials, but this has brought problem to the installation of hinge reinforcement, because the hinge reinforcement of steel plate materials can not directly weld with aluminum alloy front hood back head, structural strength can be had influence on by other means connections, or production difficulty can be increased.On the other hand, because the weight of the hinge reinforcement of steel plate materials is large, be unfavorable for front shroud assembly loss of weight, automotive light weight technology is not contributed.
Therefore,, for the use of aluminum alloy front hood back head, need to design other hinge installation reinforcing structure and coordinate with it.
Utility model content
The purpose of this utility model is, for car lightweight requirements, to provide a kind of hinge installation reinforcing structure, solves assembly problem and the performance issue of front hood hinge reinforcement and aluminum alloy front hood back head, meets the needs of automotive light weight technology simultaneously.
The technical solution of the utility model is as follows:
A kind of automotive hinge reinforced structure for installation, it comprises aluminum alloy front hood back head, aluminum alloy hinge reinforcement and steel hinge; Described aluminum alloy hinge reinforcement is a platy structure, and its base portion is nut attachment face, and nut attachment face is extended with inner panel binding face to a side, the one side laminating of nut attachment face and inner panel binding face and aluminum alloy front hood back head, and be riveted together; On described nut attachment face, be provided with boss structure, on boss, be suppressed with self-clinching nut; Described steel hinge is connected with the self-clinching nut aluminum alloy hinge reinforcement by bolt from the another side of aluminum alloy front hood back head.
Said structure, hinge reinforcement adopts aluminium alloy plate punching press to replace steel stamping part, by reasonable design inner panel binding face, ensure that hinge reinforcement is connected with the tight of aluminum alloy front hood back head, by design self-clinching nut mounting structure, realize the reliable installation of steel hinge, ensure that the intensity of installing meets performance requriements, the overall performances such as front shroud assembly stiffness also get a promotion.Meanwhile, because aluminum alloy is 1/3rd of steel density, this hinge reinforcement adopts after aluminum alloy, can reach single-piece loss of weight more than 30%, meets the needs of automotive light weight technology simultaneously.

Detailed description of the invention
Describe structure of the present utility model in detail below in conjunction with accompanying drawing: and the boss structure of middle part nut location.
Referring to Fig. 1, in order to adapt to the needs of aluminum alloy front hood back head, the utility model adopts aluminum alloy hinge reinforcement 4, the shape structure of this reinforcement, and base portion is nut attachment face 3, has extended to form inner panel binding face in nut attachment face 3 one sides.Be that conventional hinge reinforcement is generally nut attachment face and the very little turnup structure of surrounding of fitting with inner panel.The utility model is cancelled rear side turnup structure, on nut attachment face basis, extend back, form inner panel binding face and the inner panel laminating of a similar turnup structure, this inner panel binding face is connected with front hood back head 11 by rivet 7 simultaneously together with nut attachment face 3, this structure, in meeting hinge installation strength, has also played improvement effect to the stiffness of aluminum alloy front shroud assembly.
Preferably, referring to Fig. 3, inner panel binding face comprises the first binding face 1 and the second binding face 2 that extend to form with the curved shape of aluminum alloy front hood back head 4, between the first binding face and the second binding face, be the bending place corresponding to bending position of aluminum alloy front hood back head, herein and between front hood back head 11, leave the first gap 14, ensure that aluminum alloy hinge reinforcement can fit with aluminum alloy front hood back head.
Further, the also bending position of corresponding place's aluminum alloy front hood back head between the first binding face 1 and nut attachment face 3, herein and between front hood back head 11, form the second gap 13, further ensures that aluminum alloy hinge reinforcement can fit with aluminum alloy front hood back head.
Referring to Fig. 2, on this external nut attachment face, increase by two boss structures, on boss 5, open in advance rectangular opening, at rectangular opening place compacting self-clinching nut 8, steel hinge 10 is connected with the self-clinching nut 8 on aluminum alloy hinge reinforcement by bolt 9.After realizing self-clinching nut and be pressed into by newly-increased boss structure, between self-clinching nut 8 and aluminum alloy front hood back head 11, there is small third space 12, further ensure that aluminum alloy hinge reinforcement can fit with aluminum alloy front hood back head.On boss 5, open in advance rectangular opening, on the one hand can better captive nut compared with circular port, remove on the other hand the excess stock of nut location, be convenient to nut and press.
In the time that aluminum alloy hinge reinforcement is installed, aluminum alloy hinge reinforcement 4 need to, to realize hinge reinforcement location by mounting-positioning holes 6, then be riveted with aluminum alloy front hood back head 11.
By above structure, in meeting hinge installation reinforcing property, can promote the stiffness of front shroud entirety.
