Description
Technical field
The present invention relates to technical field of automobile parts, in particular to a kind of automobile back door sheet metal structural.
Background technique
Existing automobile back door metal plate generally splits into outside plate assembly and inner panel assembly.The backdoor inner plate of part vehicle often by
In factors such as moulding, cause it is too deep in taillight mouth top press depth, can not drawing and moulding.General vehicle is here often interior
Plate splits into two pieces of processing, and to reduce punching press difficulty, but this mode piecemeal is more, complex process.The present invention utilize inner panel herein
Stiffening plate structure, stiffening plate is expanded, instead of the piecemeal of inner panel here, same effect can be reached, reduce piecemeal,
Reduce technology difficulty.
Summary of the invention
The purpose of the invention is to overcome in the prior art backdoor inner plate split into muti-piece processing, Joining Technology is multiple between plate
Miscellaneous defect, and a kind of automobile back door sheet metal structural is provided.
A kind of automobile back door sheet metal structural, including tailgate outside plate upper plate, tailgate outside plate lower plate, tail light box, backdoor inner plate and
Gas spring stiffening plate, tailgate outside plate upper plate and tailgate outside plate lower plate are connected to one by the turnup structure spot welding to headstock direction
It rises, tail light box is welded on tailgate outside plate lower plate two sides, forms tailgate outside plate assembly, and backdoor inner plate outputs L-type on tail light box top
Gap, the L-type gap region outputed, mainly be exactly backdoor inner plate press depth it is too deep can not molding region, remove this region,
It can be formed in favor of backdoor inner plate, gas spring stiffening plate designs l-shaped section structure and overlaps and put with backdoor inner plate and is welded in
Together, gas spring stiffening plate just filled up the L-type gap that backdoor inner plate is outputed, backdoor inner plate and gas spring stiffening plate with back
It is linked together with tailgate outside plate assembly by pressing mode at the binding face of external door panel assembly, the gas spring stiffening plate
On L-type facade, fixed mounting hole is set.
Preferably, gas spring stiffening plate with tail light box matching position, take T-type docking mode.
Beneficial effects of the present invention:
The cooperation of gas spring stiffening plate L-type section structure, backdoor inner plate L-type gap and fixed mounting hole that the present invention uses
Form reduces piecemeal, reduces technology difficulty, improves production efficiency, has saved cost, alleviates the labour of staff
Intensity.

Specific embodiment
It please refers to shown in Fig. 1 to Fig. 6, under a kind of automobile back door sheet metal structural, including tailgate outside plate upper plate 1, tailgate outside plate
Plate 2, tail light box 3, backdoor inner plate 4 and gas spring stiffening plate 5, (please referring to shown in Fig. 3 and Fig. 4) tailgate outside plate upper plate 1 and tailgate
Outside plate lower plate 2 is linked together by the turnup structure spot welding to headstock direction, and tail light box 3 is welded on 2 liang of tailgate outside plate lower plate
Side, forms tailgate outside plate assembly, and (please referring to shown in Fig. 2) backdoor inner plate 4 outputs L-type gap D, the L outputed on 3 top of tail light box
The region type gap D, mainly be exactly 4 press depth of backdoor inner plate it is too deep can not molding region, remove this region, can in favor of carry on the back
Door inner panel 4 form, gas spring stiffening plate 5 design l-shaped section structure and with backdoor inner plate 4 overlap joint and spot-welded together, gas
Spring stiffening plate 5 just filled up the L-type gap D that backdoor inner plate 4 is outputed, backdoor inner plate 4 and gas spring stiffening plate 5 with tailgate
It is linked together with tailgate outside plate assembly by pressing mode at the binding face of outside plate assembly, the L of the gas spring stiffening plate 5
On type facade, fixed mounting hole E is set.
Preferably, gas spring stiffening plate 5 with 3 matching position of tail light box, take T-type docking mode.
The working principle of the invention and use process:
(please referring to shown in Fig. 3 and Fig. 4) tailgate outside plate upper plate 1 and tailgate outside plate lower plate 2 are by the flange to headstock direction
Structure spot welding links together, and tail light box 3 is welded on 2 two sides of tailgate outside plate lower plate, forms tailgate outside plate assembly, (please refers to Fig. 2
It is shown), backdoor inner plate 4 outputs L-type gap D on 3 top of tail light box, the L-type gap D outputed, is exactly mainly 4 punching press of backdoor inner plate
Depth it is too deep can not molding region, remove this region, can be in favor of the molding of backdoor inner plate 4, while by 4 back side of backdoor inner plate
Gas spring stiffening plate 5 expand, and design l-shaped section structure and with backdoor inner plate 4 overlap joint and spot-welded together, gas spring
Stiffening plate 5 has just filled up the L-type gap D that backdoor inner plate 4 is outputed, while on the L-type facade of gas spring stiffening plate 5, setting
Fixed mounting hole E is conveniently designed to gas spring fixed point or gas spring bracket fixed point.Finally, backdoor inner plate 4 and gas spring add
Strong plate 5 synthesizes tailgate assembly by the technology mode pressed with tailgate outside plate assembly.Gas spring stiffening plate 5 with tail light box 3
Matching position, takes T-type docking mode, and the gap of docking structure is conducive to later period gluing encapsulation process.
