The invention discloses a vehicle body doorsill structure and a vehicle body, and relates to the technical field of vehicle manufacturing, the vehicle body doorsill structure comprises a doorsill inner plate, a structure reinforcing rubber block and a doorsill reinforcing plate, and the structure reinforcing rubber block is arranged in a cavity defined by the doorsill inner plate and the doorsill reinforcing plate; a first through hole is formed in the upper side of the threshold inner plate, the structure reinforcing rubber block is provided with a first electrophoresis channel and a second electrophoresis channel, a second through hole is formed in the upper side of the threshold reinforcing plate, and the first through hole, the first electrophoresis channel, the second electrophoresis channel and the second through hole form a first channel path of electrophoresis liquid and an electric field; a third through hole is formed in the lower side of the threshold reinforcing plate, a third electrophoresis channel corresponding to the third through hole is formed in the structure reinforcing rubber block, and the third through hole, the third electrophoresis channel and the second through hole form a second channel path of the electrophoresis liquid and the electric field. Two channel paths are formed, it is guaranteed that the threshold outer cavity electrophoresis film thickness is increased, and the standard requirement for corrosion resistance is met.
本发明公开了一种车身门槛结构及车身,涉及车辆制造技术领域,包括门槛内板、结构增强胶块、门槛加强板,所述结构增强胶块设于门槛内板和门槛加强板围合成的空腔内;所述门槛内板上侧开设第一通孔,结构增强胶块设置第一电泳通道和第二电泳通道,门槛加强板上侧开设第二通孔,所述第一通孔、第一电泳通道、第二电泳通道以及第二通孔形成电泳液及电场的第一通道路径;所述门槛加强板下侧开设第三通孔,结构增强胶块对应于第三通孔设置第三电泳通道,所述第三通孔、第三电泳通道以及第二通孔形成电泳液及电场的第二通道路径。本发明形成两种通道路径,保证门槛外腔电泳膜厚的提升,达成防腐性能标准要求。
