The invention relates to the field of vehicle structures, and in particular relates to a D-column upper connector structure. The structure comprises an outer wheel cover, a rear top cross beam and D column reinforcing plates arranged on a D column, the D-column reinforcing plates are located at the left end and the right end of the rear top cross beam, the upper ends and the lower ends of the D-column reinforcing plates are connected with the rear top cross beam and the outer wheel cover respectively, the upper ends of the D-column reinforcing plates are connected with the rear top cross beamthrough D-column upper connectors, each D-column upper connector is provided with two connectors, one connector is connected with the rear top cross beam, and the other connector is connected with a D-column reinforcing plate. The D column upper connector structure is improved, the two-connector structure is adopted; compared with a three-connector structure, the two-connector structure has the advantages that the stamping difficulty is greatly lowered, the precision is greatly improved, the stamping procedures are reduced, and the die requirement is correspondingly lowered.

    本发明涉及车辆结构领域,尤其涉及一种D柱上接头结构。它包括外轮罩、后顶横梁及设在D柱上的D柱加强板,D柱加强板位于后顶横梁的左右两端,D柱加强板的上下两端分别与后顶横梁及外轮罩连接,所述D柱加强板的上端通过D柱上接头与后顶横梁连接,D柱上接头上具有两个接头,其中一个接头连接后顶横梁,另一个接头连接D柱加强板。本发明改进了D柱上接头结构,采用两接头结构,相比于三接头结构,大大降低了冲压难度,大幅度提升精度并减少了冲压工序,模具要求也相应降低。
