Description
Technical field
The utility model relates to the linkage of a kind of arrangements for automotive doors and vehicle body, is specifically related to a kind of automobile door hinge.
Background technology
Body hinge has two basic functions: the first couples together car door and vehicle body and guarantees and keep car door relatively and the position of vehicle body; It two is the foldings that guarantee and be convenient to car door.
First basic function of body hinge is that car door and vehicle body are coupled together and guarantee and keep car door relatively and the position of vehicle body.This just requires the installed surface between body hinge and car door and the vehicle body must be smooth, if lean on bolted body hinge, the relative size between vehicle body, car door spare bolt mounting holes must meet size and stable.
Consider that body hinge need bear the weight of car door and bear other strength often; When car door bore extra force, the car door position can change, and some changes when extra force is removed change can be restored (we are referred to as elastic deformation); But some changes then can not be restored (we are referred to as plastic strain); If elasticity, plastic strain are too much, will cause the car door position than about-face, thereby influence outward appearance.Therefore the requirement to body hinge is: body hinge will have certain rigid, and the elasticity when bearing certain strength and amount of plastic deformation need meet the demands.
Second basic function of body hinge is: guarantee and be convenient to the folding of car door.Because the use of automobile has certain quality guarantee time limit, we not only require body hinge when just dispatching from the factory, can satisfy this function, after using after a while, perhaps still can keep this function after the certain number of times of car door folding.Therefore the requirement to body hinge is: body hinge will have certain durability.After using after a while, the wearing and tearing of each functional part need controlled.
Lateral impact when taking place in automobile, and car door can bear bigger bump strength, and when car door bore bump, body hinge can not be thrown off to be caused car door to be banged in the member railway carriage or compartment to endanger occupant safety.Therefore the requirement to hinge is: body hinge can not be thrown off between vehicle body and the car door when bearing certain strength.
Existing body hinge is mainly assembled by vehicle body spare, car door spare, bearing pin, pad and lining, for the door hinge structure of prior art structure, to the function of hinge and require the defective in actual production is used mainly to show as:
One, facial smooth or installing hole size being installed does not match.Cause the reason of this defective to be roughly. vehicle body door opening, car door size, body hinge size, the improper formation that cooperatively interacts.On vehicle body doorframe and car door size certain basis, the size of body hinge will influence all even uniformity in slit.Some elastic properties of materials deformation ratio is bigger, causes hinge dimensions unstable.
Two, hinge elasticity and amount of plastic deformation do not meet the demands, intensity and insufficient rigidity.Influence factor is: the gap between the rigidity of car door, vehicle body spare material, the rigidity of bearing pin, each position.Certain type of hinge adopts the panel beating moulding process, and because of the thickness that is subject to panel beating and the restriction of design of part, the external force that the part after the moulding can bear is limited; After continuing stand under load; Part is whole or local yielding, and for hinge, external to show as car door sagging; The peripheral slit of car door and car body is inhomogeneous, influences the normal use of door lock.
Summary of the invention
