The invention discloses a door sealing structure and an optimization design method. The vehicle door sealing structure comprises a sealing piece arranged at the bottom of a vehicle door, and the sealing piece is matched with a sealing face on a vehicle body to achieve sealing between the bottom of the vehicle door and the vehicle body. The sealing piece comprises a sealing retainer meeting the sethardness requirement, the bottom of the sealing retainer is provided with an inwards-concave arc face in the length direction, and the arc face is matched with a protrusion on a vehicle body sealingface. A soft sealing layer is laid on the arc face, and the soft sealing layer enables the arc face to be in tight coupling contact with the protrusion. According to the vehicle door sealing structure, external noise transmitted into passenger room space can be reduced, the comfort of passengers is improved, meanwhile, corrosion of dust, rainwater and the like to the vehicle door and parts nearbythe vehicle door is effectively prevented, and the service life of the vehicle door is prolonged.

    本发明公开了一种车门密封结构及优化设计方法,包括设置在车门底部的密封件,所述密封件与车体上的密封面配合,实现车门底部与车体之间的密封;所述密封件包括:满足设定硬度要求的密封保持架,所述密封保持架底部在长度方向上设有内凹的弧面,所述弧面与车体密封面上的凸起相匹配;所述弧面上敷设软质密封层,所述软质密封层能够使得所述弧面与所述凸起紧密耦合接触。本发明车门密封结构能够减少外部噪音传入客室空间,提高乘员舒适性,同时有效阻止粉尘、雨水等对车门及其附近零部件的侵蚀,延长车门的使用寿命。
