Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Referring to Fig. 1-9, a kind of rear side door of automobile reinforcement structure has：
Rear door body；
Windowsill external reinforcing plate for car, is arranged at the windowsill on rear door body；
Waling, is arranged in the middle part of rear door body, waling lateral arrangement；
Crash bar, is arranged on rear door body lower part；
Middle reinforcing plate, middle reinforcing plate upper end is welded with windowsill external reinforcing plate for car, and near middle is welded with waling, lower end
With bumper welding.
Support, support and bumper welding are additionally provided with crash bar, middle reinforcing plate is welded with support.
Middle reinforcing plate is arranged in a vertical direction on rear door body, and middle reinforcing plate is located at rear door body width direction
Near middle.
Timbering material is DC01, and material thickness is 1mm, and support width is 40mm, together with anti-collision rod assembly welding, is strengthened with middle
Plate weld one end stays 20mm width to be easy to welding, and the two of two 35mm length of a support protect solder joint.
Middle reinforcing plate length is 515.5mm, and width is 40mm, and material is B170P1, and material thickness is 0.7mm；Middle reinforcing plate two
End position is respectively provided with onePositioning hole is welded, will not accurately be shifted with reinforcing plate welding position in guarantee；In
Reinforcing plate two ends are additionally provided with kidney-shaped vibration isolation glue groove, and play in vibration isolation glue groove vibration isolation glue.To ensure external door panel with adding in longitudinal direction
Gap will not be produced between strong plate, causes the hollow dent resistance of outside plate can be poor.
Timbering material is DC01, material thickness be 1mm, middle reinforcement plate material be B170P1, material thickness be 0.7mm, punch forming without
Any risk.
Crash bar support is welded into anti-collision rod assembly, anti-collision rod assembly, back door with crash bar and front and rear connecting plate to be added
Strong plate, back door inner panel assembly, four part compositions of side door outside plate (punching press) are back door assembly.Crash bar support and crash bar and front and rear
Connecting plate is welded into an anti-collision rod assembly by external coordination company.
Crash bar support makes a call to the two of two long 35mm with bumper welding and protects weldering, middle reinforcing plate upper end and windowsill external reinforcing plate for car
Weld together, make a call to a solder joint；Middle part welds together with waling, makes a call to two solder joints；Lower end and crash bar support
Welding, makes a call to a solder joint.There are four long waist shaped glue grooves at middle reinforcing plate when outside plate is with inner panel assembly split and beaten in this position
Upper vibration isolation glue is very helpful to outside plate.Improve the dent resistance energy of external door panel.
CAE analysis result before and after improving：
Rear door dent resistance energy standard：
Load 250N desired value ＜ 8.0mm：
250N unloading desired value ＜ 0.3mm：
As shown in Fig. 8,9, improve pre-structure and be not inconsistent constructor standardization after standardization, improvement.
After above-mentioned structure, reinforcing plate increases with support in the middle part of the dent resistance energy of rear door outer plate, outside plate in rear door
Longitudinal direction is without support, and vibration isolation glue is played between middle reinforcing plate and outside plate effectively raising the dent resistance of outside plate can and prevent from deforming.Side door
The dent resistance of outside plate can be improved, and the integral rigidity and mode of door have also been lifted.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
