Detailed Description

It is right to combine specific embodiment below the utility model discloses a car longeron inner chamber reinforcing plate structure does further explanation to help technical staff in this field to be right the utility model discloses a technical scheme has more complete, accurate and deep understanding.

Example 1

As shown in fig. 4-6, the reinforcing plate structure for the inner cavity of the automobile longitudinal beam solves the problems of poor liquid discharge and poor electrophoresis effect when the reinforcing plate structure is arranged in the inner cavity of the longitudinal beam, ensures the circulation of coating, improves the internal electric field and improves the quality of the electrophoretic paint film. Specifically, the longitudinal beam and inner cavity reinforcing plate metal plate lap joint structure of the embodiment comprises an inner cavity reinforcing plate metal plate 10 and a longitudinal beam 20, wherein the longitudinal beam 20 comprises a longitudinal beam bottom plate 22 and longitudinal beam side plates 21 located on two sides of the longitudinal beam bottom plate 22, and a longitudinal beam fillet structure is arranged between the longitudinal beam bottom plate 22 and the longitudinal beam side edges 21. The inner cavity reinforcing plate metal plate 10 comprises a metal plate bottom plate 12 and metal plate side edges 11 located on two sides of the metal plate bottom plate 12. The sheet metal side 11 is sequentially formed with a concave bottom side 111 and an outward extending upper side 112 along the height direction, and a middle transition side 113 is arranged between the concave bottom side 111 and the outward extending upper side 112. The inner cavity reinforcing plate metal plate 10 is arranged on the longitudinal beam 20, and the metal plate bottom plate 12 is attached to and welded and fixed with the longitudinal beam bottom plate 22. An inner gap is formed between the inner concave bottom side edge 111 and the longitudinal beam side plate 21, the width of the inner gap is larger than or equal to 5mm, a closed end 13 (shown in figure 6) and a non-closed end 12 (shown in figure 5) are formed between the extension upper side edge 112 and the longitudinal beam side plate 21 through welding, the non-closed end 12 is communicated with the inner gap, and the distance between the longitudinal beam fillet structure and the sheet metal side edge 11 is larger than or equal to 5 mm. In the present embodiment, the height of the side member 21 is greater than the height of the sheet metal side 11.

In the automobile longitudinal beam inner cavity reinforcing plate structure of this embodiment, fillet laminating structure among the prior art has been cancelled (as shown in fig. 3), and the panel beating laminating of side 112 provides panel beating intensity on the extension, and interior concave bottom side 111 panel beating contains the regional increase panel beating clearance of fillet and does benefit to electric field circulation and coating circulation. In this embodiment, regional clearance is not less than 5mm in bottom and fillet, in application electrophoresis production process, carries out the flowing back through the fillet clearance, utilizes the panel beating clearance to guarantee tank liquor circulation and electric field effect, improves the electrophoresis lacquer membrane quality. The reinforcing plate structure of this embodiment, at white automobile body electrophoresis in-process, longeron and inner chamber reinforcing plate panel beating clearance increase more than 5mm, increase more than 5mm behind the regional panel beating clearance of fillet, improved inside electric field, guarantee the coating circulation, utilize the regional panel beating clearance of fillet to carry out the flowing back simultaneously, promote corrosion resisting property, the on-the-spot electrophoresis of verifying is respond well.
