AI Technical Summary
In the prior art, during the electrophoretic coating process of the rear storage box front support of the vehicle, the electrophoretic liquid is difficult to completely flow out of the hollow tubular interior, resulting in internal corrosion problems.
Leave holes at the flattened parts at both ends of the support body to ensure that the electrophoretic liquid can flow out through these holes, achieving electrophoretic coating on the outer surface and internal drying.
It realizes effective electrophoretic coating of the front support of the rear storage box of the car, avoids internal corrosion and maintains good anti-corrosion performance.

Abstract
Description
Technical Field
[0001] The utility model relates to a front support member of an automobile rear storage box. Background Art
[0002] The front support member of the automobile rear storage box is located inside the storage box and is a metal tubular part with painted finish, which is directly assembled in the storage box to support the storage box.
[0003] The front support member of the rear storage box is constructed as a hollow tubular part. Both ends of the tubular metal part are flattened, and there is a hole in the middle of the flattened plane for bolt assembly. The hollow tubular part can well improve the rigidity of the front support member of the rear storage box and enable it to have a good supporting effect.
[0004] This part is directly assembled in the storage box in the general assembly workshop. To have good anti-corrosion function, its outer surface must be painted. The process with good paint performance and good economy is cathodic electrophoretic paint. Electrophoretic paint uses the good electrical conductivity of metal parts to adsorb paint particles onto the part surface in the electrophoretic solution to form a dense paint coating. Therefore, the part must pass through the electrophoretic solution. Since there are holes at both ends of the part and there may be gaps after flattening, when the part passes through the electrophoretic solution, the electrophoretic solution will inevitably enter the hollow part of the tubular part and is not easy to flow out. This causes the electrophoretic solution to remain in the inner cavity of the tubular part and corrode the inner cavity. Summary of the Invention
[0005] The technical solution provided by the utility model is: a front support member of an automobile rear storage box, including a support member body. The surface of the support member body has an electrophoretic paint layer. The middle part of the support member body is in a hollow tubular shape. Both ends of the support member body are flattened into a flat shape. There is a bolt through-hole in the middle of the flat end surface. There are holes on the end surface of the flat end that are communicated with the hollow of the hollow tubular middle part of the support member body.
[0006] There are two such holes, and the two holes are located on both sides of the flat end of the support member body.
[0007] The bolt through-hole at one end of the support member body is a round hole, and the bolt through-hole at the other end of the support member body is an oval hole.
[0008] The utility model leaves holes at the flattened parts at both ends for the electrophoretic paint to pass through. In this way, when the part is processed with electrophoretic paint through the electrophoretic tank, the electrophoretic solution entering the cavity inside the hollow tubular middle part of the support member body can conveniently flow out through the holes. In this way, not only the outer surface of the part is well painted with electrophoretic paint, but also the inside of the cavity is kept dry, making it have good anti-corrosion performance. Brief Description of the Drawings
[0009] Figure 1 It is a schematic structural diagram of the utility model. Detailed Description of the Invention
[0010] See Figure 1 , the utility model comprises a support body 1, the surface of the support body 1 has an electrophoretic paint layer, the middle part of the support body 1 is in a hollow tubular shape, the two ends of the support body 1 are flattened into a flat shape, and there is a bolt through-hole in the middle of the plane of the flattened end. Among them, the bolt through-hole at one end of the support body 1 is a round hole 2 with a diameter of Ø10, and the bolt through-hole at the other end of the support body 1 is an oblong hole 3 with a size of 12*16. There are holes 4 on the end face of the flattened end, which are communicated with the hollow part in the middle of the support body.
[0011] There are two such holes, and the two holes are located on both sides of the flattened end of the support body.
[0012] The utility model has holes on both sides of the flattened parts at both ends for facilitating the passage of electrophoretic paint. After the parts are formed, when processing electrophoretic paint through an electrophoretic tank, the electrophoretic liquid entering the cavity inside the hollow tubular middle part of the support body can conveniently flow out through the holes. In this way, the outer surface of the parts is well coated with electrophoretic paint, and the inside of the cavity is kept dry without residual electrophoretic liquid, avoiding internal corrosion of the tubular parts.
