Background technology
Body hinge nutplate is to realize that body hinge connects very important part with car door metal plate, larger in order to ensure
Screw-down torque, traditional body hinge nutplate is with the thicker cold pier of plank, and material is thicker, usually 4mm, volume compared with
Greatly, therefore cost is higher, and weight is per single-piece about 64g, bicycle about 512g.
Threaded hole and welding hole are provided in the nutplate of traditional vehicle door hinge side, requirement part and connector plane are complete in welding
Complete zero patch, it is higher to part punching technique and welding process requirement, if fitting completely, bolt are not easier to produce after entering for part
Caused by raw nutplate deformation the problems such as torque attenuation.
Therefore, it is necessary to develop a kind of novel hinge for vehicle door nutplate of lightweight high-intensity, solve and connector plane
The problem on deformation being also easy to produce when being not exclusively bonded.
Invention content
The purpose of this utility model seeks to solve the deficiency of above-mentioned background technology, provides a kind of the new of lightweight high-intensity
Type body hinge nutplate solves the problem on deformation being also easy to produce when being not exclusively bonded with connector plane.
The technical solution of the utility model is：A kind of novel hinge for vehicle door nutplate, including being threaded hole, welding hole
Bottom plate, which is characterized in that the bottom plate includes periphery and prolongs upwards along the fitting plane and fitting plane inner edge of profile formation closure
The crowning to be formed is stretched, the threaded hole is located at crowning top and edge extends to form inner wall upward.
Preferably, the fitting plane, which further includes, extends inwardly to form mounting plane, and the welding hole is located at mounting plane
On.
Preferably, the bottom plate is equipped with upward flange along profile.
Further, the flange is equipped with technical gaps.
Preferably, the bottom edge is recessed positioning fillet.
Preferably, convex algorithm is set in the welding hole.
The utility model also provides a kind of above-mentioned body hinge nutplate and the connection structure of car door, which is characterized in that vehicle
Door hinge nutplate is connect with car door.
Preferably, the body hinge nutplate is welded by the hinge stiffening plate on the welding hole and car door on bottom plate
It connects, fitting plane is bonded with hinge stiffening plate.
The beneficial effects of the utility model are：
1. the fitting plane on only periphery is bonded with weldment, the risk of distortion that accessory size wave zone comes is reduced, avoids power
The problem of square is decayed.On the one hand crowning increases base plate strength, on the other hand avoid bottom plate integral planar and the patch of weldment
It closes.
2. during assembling, threaded hole is corresponding with the location hole on car door, and positioning fillet and the detent fit on car door ensure
Nutplate will not rotate, and realization is accurately positioned.Convex algorithm in welding hole is welded with hinge stiffening plate, realizes nutplate and vehicle
Door is reliably connected.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figs 1-4, body hinge nutplate 12 provided by the utility model, including being threaded hole 2, welding hole 3
Bottom plate 1, bottom plate 1 include periphery the fitting plane 4 being closed is formed along profile and be bonded plane 4 inner edge upwardly extend to be formed it is convex
Face 5 is played, threaded hole 2 is located at 5 top of crowning and edge extends to form inner wall 6 upward, and internal thread is carried on inner wall 6.
Fitting plane 4, which further includes, extends inwardly to form mounting plane 7, and welding hole 3 is located on mounting plane 7.Bottom plate 1 is along wheel
Exterior feature is equipped with continuous upward flange 8.1 edge of bottom plate is recessed positioning fillet 10.Convex algorithm 11 is set in welding hole 3.
In the present embodiment, bottom plate 1 be square block, fitting plane 4 be along profile irregular annular, in Fig. 2 left and right to
For the length direction of bottom plate 1, threaded hole 2, welding hole 3 are located on the axis of length direction.Flange 8 can be the closure along profile
Shape can also set notch, and it is the continuous production for part that the present embodiment, which is equipped with technical gaps 9,.Bottom plate 1 is close to threaded hole 2
One end both sides are designed with positioning fillet 10, are that can coordinate limiting with bottom plate 1 in order to which positioning pin is located at 1 either side of bottom plate.
As shown in figure 5, body hinge nutplate and the connection structure of car door are：
The threaded hole 2 of body hinge nutplate 12 is corresponding with the hole on the hinge stiffening plate 13 on car door, recycle weldering
