Description
Technical field
The utility model relates to vehicle body attaching parts field, particularly relates to fibre reinforced bodywork component and is fastenedly connected rubber bush anti-corrosion structure.
Background technology
In recent years, in the face of the environment that goes from bad to worse and the high reality of oil resources external dependence degree, automotive light weight technology become national energy-saving reduce discharging strategy in the urgent need to, more become the current demand that core competence improves in car enterprise.And carbon fiber enhancement resin base composite material has, and strength-to-density ratio is high, specific modulus is high, fatigue durability is excellent, performance can design and be easy to many excellent specific properties such as global formation, be widely used in the industrial circles such as aerospace.
In auto-industry, adopt carbon fiber enhancement resin base composite material to replace traditional ferrous materials and can realize loss of weight 30% ~ 50%, there is huge application potential.The application major part of carbon fiber composite material part on automobile adopts to glued joint and connects, then need for there being the part of detachable maintaining demand to use bolt to be fastenedly connected, but because carbon fiber composite material has the current potential of calibration, be about 300mV, aluminum alloy conventional on automobile, alloy steel material then have comparatively negative current potential, be respectively-780mV and about-730mV, carbon fiber composite material and aluminum alloy and alloy steel material are connected directly between trend thermodynamics having galvanic corrosion.For preventing the generation of galvanic corrosion, usually select the fasteners such as the titanium close with carbon fiber composite material current potential, titanium alloy, and carry out wet assembling with carbon fibre reinforced composite part, cost is higher.
Utility model content
Technical problem to be solved in the utility model is that to realize a kind of cost low, and has the bodywork component connection structure of preventing galvanic corrosion effect.
To achieve these goals, the technical solution adopted in the utility model is: a kind of bodywork component connection structure, comprise binding bolt, pad, clamp nut and rubber bush, described rubber bush is column structure and is provided with the through hole passed for binding bolt, described rubber bush one end is provided with flange, and the other end is provided with the turnup structure of spacing washer and bodywork component.
Described turnup structure is made up of the bar shaped perforate crimp that rubber bush is arranged along axis, and described perforate is at least provided with three.
Described turnup structure is made up of the bar shaped fluting crimp that rubber bush is arranged along axis, and described fluting is at least provided with three.
The counterbore placing binding bolt bolt cap is provided with between the through hole of described rubber bush and flange.
Interference fit between described binding bolt and rubber bush.
The utility model fibre reinforced bodywork component connects anti-corrosion structure and adopts binding bolt to avoid metal fastenings to contact with the carbon filament exposed after the perforate of fibre reinforced bodywork component with the mode that rubber bush combines, thus effectively can prevent galvanic corrosion, the fasteners such as titanium alloy need not be adopted simultaneously, wet assembly technology need not be adopted, significantly reduce costs, and be convenient to detachable maintaining.

Detailed description of the invention
As shown in Figure 1, 2; the utility model is at binding bolt 3 and be provided with an independently rubber bush 4 outward; rubber bush 4 is column structure and is provided with the through hole 43 passed for binding bolt 3; glue lining one end is provided with flange 41; the counterbore 42 of the bolt cap placing binding bolt 3 is provided with, for the protection of bolt cap between the through hole 43 of rubber bush 4 and flange 41.The other end of rubber bush 4 is provided with the turnup structure of spacing washer 2 and bodywork component 5.As shown in Figure 3, turnup structure is made up of bar shaped perforate 46 crimp that rubber bush 4 is arranged along axis, and perforate 46 is at least provided with three; Turnup structure is made up of bar shaped 45 crimps of slotting that rubber bush 4 is arranged along axis as shown in Figure 4, and fluting 45 is at least provided with three.Binding bolt 3 and rubber bush 4 interference fit, binding bolt 3 closely cooperates through rubber bush 4 and fibre reinforced bodywork component 5 hole.
The installation method of the utility model body connection structure is as follows: when bodywork component 5 is fastenedly connected assembling, first the sleeve pipe 44 of rubber bush 4 is put into bodywork component 5 connecting bore 51, rubber bush 4 flange 41 and bodywork component 5 surface engagement, then insert in the through hole 43 of rubber bush 4 by binding bolt 3, binding bolt 3 end coordinates with the counterbore 42 of rubber bush 4; Pad 2 is enclosed within binding bolt 3 screw mandrel end, screw clamp nut 1, screwing in the process of pressing down slot 45 or the abundant flexing of perforate 46 part tubular 44 or stretching, extension with isolation pad 2 and bodywork component 5, ensure that binding bolt 3 and bodywork component 5 fully isolate to prevent galvanic corrosion.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
