Examples

An embodiment of the utility model provides a vehicle, this vehicle includes the white automobile body.

Body-in-white refers to an unpainted body that is a body structure and panel weld assembly and includes front wings, doors, hoods, trunk lids, but does not include accessories and trim.

The outer plate of the B column of the existing vehicle body is the whole side wall outer plate, and the inner plate of the B column, the threshold of the reinforcing plate and the top cross beam are welded together. Because the inner plate and the outer plate of the B column and the reinforcing plate doorsill are positioned at different welding levels, the outer plate of the B column is positioned at the final process of welding the vehicle body assembly during welding. And the existing automobile B column is of a steel sheet metal stamping structure, so that the B column can be subjected to integral electrophoresis only after being integrally welded with a white automobile body. The B column cannot be connected with other vehicle bodies such as a floor after being subjected to independent electrophoresis, so that huge energy consumption is caused.

In addition, when the other structures of the automobile body except the B column are all aluminum alloy plates, the plates have better corrosion resistance due to 5-series 6-series type for automobiles. The other structures of the car body except the B column do not need electrophoresis, and the connection of the steel B column and the aluminum alloy car body is mostly cold connection processes such as SPR, FDS or rivet pulling. Most cold connection processes are plastic deformation connection, and a paint film on the surface of the B column after electrophoresis is damaged, so that the corrosion resistance is influenced.

Note: the SPR self-piercing rivet connection process is a connection process in which an SPR self-piercing rivet is pressed into a connected workpiece through a riveting pliers, and an interlocking structure is formed at a rivet cake position. The method specifically comprises four stages of clamping → blanking → expanding → riveting. After the SPR riveting is finished, a button-shaped combination part is formed on the surface of the metal plate.

The principle of the FDS flow drill screw connection process is that high-strength steel, aluminum alloy and other metals are heated to a molten state through high-speed rotation, namely the FDS flow drill screw generates heat through friction between the FDS flow drill screw and the surface of a connected part through high-speed rotation, melts the connected part, and processes threads and screws while tapping the part. The method comprises six stages of rotation (heating) → penetration → through hole → tapping → screwing → fastening. The FDS is essentially a self-tapping screw, and is required to be screwed with a metal plate, so that the FDS has certain requirements on the flatness of a plane, and is mainly used for connection between planes at present.

The embodiments of the present application improve on the above-mentioned problem, thereby providing a split type B-pillar. The split type B column can independently realize electrophoresis, so that the production cost is reduced, and the corrosion prevention requirement of a connected white automobile body is met.
