It aims at providing a door planking reinforcing plate structure for prolonging the service life of a door planking. The technical solution disclosed in this patent document is a useful attempt in the technical field.
Disclosure of Invention
The utility model aims at providing a door planking additional strengthening, it can be when strengthening the door planking, avoid appearing electrophoresis harmfully, corrosion problem to reduce cost.
A door planking additional strengthening, including door planking and door inner panel, the door planking passes through lock and door inner panel connection, vacuole formation structure, characterized by between the two:
the automobile door frame is characterized in that a transverse upper reinforcing piece is arranged at a position, close to the lower edge of an automobile door window frame, of the automobile door inner plate, a transverse middle reinforcing piece is arranged in the middle of the automobile door inner plate, a transverse lower reinforcing piece is arranged at the lower part of the automobile door inner plate, and two ends of the upper reinforcing piece, the middle reinforcing piece and the lower reinforcing piece are connected with the automobile door inner plate through spot welding; the minimum distance between the middle parts of the upper reinforcing part, the middle reinforcing part and the lower reinforcing part and the inner side of the outer plate of the vehicle door is 2.5 mm.
Furthermore, a plurality of grooves are respectively arranged on the upper edge and the lower edge of the middle part of the upper reinforcing piece, the middle reinforcing piece and the lower reinforcing piece, and expansion glue is fully coated in each groove.
Furthermore, six grooves are formed in the upper edge and the lower edge of the middle of the upper reinforcing piece.
Further, nine grooves are formed in the upper edge and the lower edge of the middle reinforcing piece.
Further, nine grooves are formed in the upper edge and the lower edge of the middle of the lower reinforcing piece.
The utility model has the advantages that:
because the door inner panel has set up the reinforcement, well reinforcement and reinforcement down, and at last reinforcement, set up a plurality of recesses on well reinforcement and the reinforcement down, be full of the inflation glue in the recess, the inflation glue is through the foaming sclerosis after the application heating toasts, with fixed connection at the last reinforcement of door inner panel, well reinforcement, with reinforcement combined action support door planking down together, thereby play the effect of strengthening the door planking, the intensity and the rigidity of door planking have been improved, and be superior to current structure. Simultaneously, cancel the reinforcement film, not only can reduce the manufacturing operation degree of difficulty, avoid appearing electrophoresis harmfully, corrosion problem, but also can reduce cost.
