The invention provides a D-column upper joint structure, a vehicle body structure and a vehicle, the D-column upper joint structure comprises a D-column reinforcing plate, a D-column inner plate, a first supporting bracket and a second supporting bracket, the D-column reinforcing plate is mounted on the D-column inner plate and defines a cavity structure, and the D-column reinforcing plate is provided with a hinge mounting area and a supporting rod bracket mounting area; the first supporting bracket and the second supporting bracket are both located in the cavity structure, the two opposite ends of the first supporting bracket are connected to the hinge mounting area and the D-column inner plate correspondingly, and the two opposite ends of the second supporting bracket are connected to the supporting rod bracket mounting area and the D-column inner plate correspondingly. When external force acts on the hinge installation area and the supporting rod support installation area, the first supporting support and the second supporting support can transmit the acting force to the D column inner plate, the structural strength of the hinge installation area and the supporting rod support installation area is improved, the thickness of the plate is not changed, and the weight and cost cannot be greatly increased.

    本发明提供了一种D柱上接头结构、车身结构及车辆,该D柱上接头结构包括D柱加强板、D柱内板、第一支撑支架和第二支撑支架,D柱加强板安装于D柱内板上并围成空腔结构,D柱加强板具有铰链安装区域和撑杆支架安装区域,第一支撑支架和第二支撑支架均位于空腔结构内,且第一支撑支架的相对两端分别连接于铰链安装区域和D柱内板,第二支撑支架的相对两端分别连接于撑杆支架安装区域和D柱内板。当外力作用于铰链安装区域和撑杆支架安装区域时,第一支撑支架和第二支撑支架可以将作用力传递至D柱内板上,即增加了铰链安装区域和撑杆支架安装区域的结构强度,并且没有改变板材的厚度,不会导致重量和成本大幅增。
