The utility model aims at providing a welded structure of car qianmen planking reinforcement, the technical problem of solution: the gusset is gone up in the qianmen to tradition and welding that tradition qianmen planking reinforcement is independent each other on traditional qianmen inner panel, and the rigidity of qianmen can not be guaranteed, and the solder joint is many, and the solder joint quality is difficult to handle accuse, and manufacturing procedure is many, and the cost increases.
In order to solve the technical problem, the utility model discloses a following technical scheme: a welding structure of a reinforcement of an outer plate of a front door of an automobile comprises a reinforcement of the outer plate of the front door, which is welded on an inner plate of the front door and used for reinforcing the rigidity of the outer plate of the front door; the front end part of the front door outer plate reinforcing part is welded with the lower end of the front door upper angle plate.
As right the utility model discloses a further improvement, preceding tip welding of qianmen planking reinforcement is on the lateral surface of the inner panel welding part of the corner plate lower extreme in the qianmen.
As a further improvement of the utility model, the front end part of the front door outer plate reinforcement is an upper corner plate welding part, and a reinforcement plug welding hole is formed in the upper corner plate welding part;
an upper corner plate plug welding hole is formed in the inner plate welding part;
and the outer plate reinforcing piece, the front door upper angle plate and the front door inner plate are welded into a whole through the reinforcing piece plug welding hole and the upper angle plate plug welding hole.
By adopting the technical scheme, the utility model discloses the beneficial technological effect who reaches as follows:
firstly, the front door upper corner plate and the front door outer plate reinforcing piece are welded and combined, so that the front door upper corner plate, the front door outer plate reinforcing piece and the front door inner plate are integrated, the rigidity of the front door is improved, and the front door is not easy to deform under bumpy road conditions.
Secondly, welding spots are reduced, processing procedures are reduced, the quality of the welding spots is easy to control, the processing cost is saved, and the appearance is attractive. We assume that qianmen planking reinforcement is through two solder joints welding on qianmen inner panel, and preceding scute of qianmen welds on preceding door inner panel through two solder joints, so have four solder joints to weld just with preceding planking reinforcement, preceding scute of qianmen on preceding door inner panel totally on preceding door inner panel, and the utility model discloses a plug the welding hole with the reinforcement and correspond the setting with the upper scute plug welding hole (with reinforcement preceding tip welding at inner panel welding portion lateral surface), can be as an organic whole with preceding planking reinforcement of qianmen, preceding scute of qianmen and preceding door inner panel welding through two solder joints.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 to 3, a welding structure of a reinforcement for an outer panel of a front door of an automobile includes a reinforcement 1 for an outer panel of a front door welded to an inner panel of a front door and used for reinforcing the rigidity of the outer panel of the front door; the front end of the front door outer plate reinforcement 1 is welded with the lower end of the front door upper corner plate 2.
In the present embodiment, the front end portion of the front door outer panel reinforcement 1 is welded to the outer surface of the inner panel welding portion 21 at the lower end of the front door gusset 2.
In the embodiment, the front end part of the front door outer panel reinforcement 1 is an upper panel welding part 11, and a reinforcement plug welding hole 111 is formed in the upper panel welding part 11;
an upper corner plate plug welding hole 211 is formed in the inner plate welding portion 21;
the reinforcement plug welding hole 111 on the front door outer plate reinforcement 1 corresponds to the upper corner plate plug welding hole 211 on the front door upper corner plate 2, and the outer plate reinforcement 1, the front door upper corner plate 2 and the front door inner plate are welded into a whole through the reinforcement plug welding hole 111 and the upper corner plate plug welding hole 211.
The utility model discloses a with the preceding tip welding of qianmen planking reinforcement 1 on the lateral surface of the interior plate welding part 21 on the scute 2 on the qianmen, can make the quantity reduction of solder joint. Assuming that two reinforcement plug welding holes 111 are formed in the front door outer panel reinforcement 1 and two upper corner panel plug welding holes 211 are formed in the front door upper corner panel 2, four welding spots are needed to weld the front door outer panel reinforcement 1 and the front door upper corner panel 2 to the inner panel because the upper corner panel welding part 11 and the inner panel welding part 21 are respectively welded to the front door inner panel in the conventional manner; the utility model discloses a with preceding tip welding on inner panel welding part 21 lateral surface (two reinforcement stopper welding hole 111 correspond with two upper corner plate stopper welding hole 211), can be disposable with qianmen planking reinforcement 1, preceding scute 2 welding on the qianmen inner panel through two solder joints.
Along with the reduction of welding spots, the processing procedures are reduced, the quality of the welding spots is easier to control, the cost is saved, and the appearance is attractive.
The front door upper angle plate 2 and the front door outer plate reinforcing piece 1 are welded and combined, so that the front door upper angle plate 2, the front door outer plate reinforcing piece 1 and the front door inner plate are integrated, the rigidity of the front door is improved, and the front door is not easy to deform under bumpy road conditions.
