Abstract

The invention discloses a threshold structure of a body-side outer panel. The threshold structure comprises a threshold outer panel, a threshold inner panel, the body-side outer panel and a coating electrophoresis port. The top end and the bottom end of the threshold outer panel are fixedly connected, the threshold inner panel and the threshold outer panel are enclosed to form a threshold cavity,and multiple threshold cavity drainage holes communicating with the outside are formed in the bottom end of the threshold cavity; the top end of the body-side outer panel is fixedly connected to the top end of threshold outer panel, the bottom end of the body-side outer panel is fixed on the side wall of the threshold outer panel, and the body-side outer panel and the threshold outer panel are enclosed to form a body-side threshold cavity; and the coating electrophoresis port is formed in the threshold outer panel and communicates the body-side threshold cavity with the threshold cavity, and the bottom end of the coating electrophoresis port is located at the joint position of a body-side inner panel and the side wall of the threshold outer panel. Compared with the prior art, the coating electrophoresis port in the threshold outer panel and the threshold cavity drainage holes in the lower part of the threshold cavity are utilized to form an effective drainage route, and the problem ofelectrophoresis drainage is solved during electrophoresis.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a door sill structure of a side wall outer panel of a vehicle body. Background technique [0002] Painting is one of the four major processes of vehicle production, and it is also an important factor determining the corrosion resistance of vehicles. Electrophoresis is a crucial link in painting, and the quality of the electrophoresis effect largely determines the thickness of the paint film on the body sheet metal cavity. In actual production, there are many factors that affect the effect of electrophoresis, among which the structure of the liquid inlet and discharge is an important factor that affects the effect of electrophoresis. [0003] In the existing technology, such as Figure 1-Figure 4 As shown, in the design of the side wall outer panel 100 and the door sill outer panel 200 ( Figure 8 and Figure 9 When the structure of the lap joint is shown), usuall...
