The invention discloses a C-column-free roof side rail structure, a vehicle body structure and a vehicle, and relates to the technical field of vehicle body structures.The roof side rail structure comprises a roof side rail front reinforcing outer plate, a roof side rail rear reinforcing outer plate, a skylight reinforcing ring and a skylight reinforcing cross beam, the roof side rail front reinforcing outer plate is arranged on the outer side of a B-column roof side rail inner plate, and the roof side rail rear reinforcing outer plate is arranged on the outer side of a B-column roof side rail inner plate; the front end of the roof side rail front reinforcing outer plate is connected with the column B; the roof side rail rear reinforcing outer plate is arranged on the outer side of the D column roof side rail inner plate, and the rear end of the roof side rail rear reinforcing outer plate is connected with the D column; the skylight reinforcing ring is connected with the roof side rail front reinforcing outer plate and the roof side rail rear reinforcing outer plate; the skylight reinforcing cross beam is arranged on the upper side of the skylight reinforcing ring; the rear end of the roof side rail front reinforcing outer plate is connected with the front end of the roof side rail rear reinforcing outer plate, and the connecting position is located in the middle of the skylight reinforcing cross beam. The roof side rail structure between the B column and the D column can be reinforced, deformation of the rear portion of the B column is reduced in the side collision process, and the side collision performance requirement of a C-column-free vehicle body is met.
本发明公开了一种无C柱的上边梁结构、车身结构及车辆,涉及车身结构技术领域,所述上边梁结构包括:上边梁前加强外板、上边梁后加强外板、天窗加强环和天窗加强横梁,上边梁前加强外板设于B柱上边梁内板的外侧,上边梁前加强外板的前端与B柱连接;上边梁后加强外板设于D柱上边梁内板的外侧,上边梁后加强外板的后端与D柱连接;天窗加强环与上边梁前加强外板和上边梁后加强外板连接;天窗加强横梁设于天窗加强环的上侧;上边梁前加强外板的后端与上边梁后加强外板的前端连接,且连接位置位于天窗加强横梁的中间位置。本发明能加强B柱与D柱之间的上边梁结构,在侧碰过程中减小B柱后部的变形,满足无C柱车型车身侧碰性能要求。
