The invention discloses a sealing rubber strip for an urban rail vehicle and a vehicle door system. At least one pressure balance hole is formed in the side wall of a rubber strip cavity on the inner side of the vehicle, and the side wall of a rubber strip cavity on the outer side of the vehicle is inwards concave towards the rubber strip cavity side and keeps the inwards concave trend under the working condition of negative pressure outside the vehicle; the side wall of the automobile outer side rubber strip cavity and the side wall of the automobile inner side rubber strip cavity are provided with an intersection part; an outer sealing lip and an inner sealing lip are arranged on one side, far away from the rubber strip cavity, of the intersection part; the sealing main body comprises a leaning arm connected between the anchor point mounting part and the side wall of the vehicle outer side rubber strip cavity, and the intersection point of the leaning arm and the side wall of the vehicle outer side rubber strip cavity is located on the side, away from the anchor point mounting part, of the intersection part and the vertical line of the leaning arm. According to the sealing rubber strip, when a door is closed, the rebound force of the rubber strip is small, and the good dynamic sealing performance can be achieved even if the initial compression amount is small under the negative pressure working condition of the vehicle door.

    本发明公开了一种城轨车辆用密封胶条及车门系统,车内侧胶条空腔侧壁上设有至少一个压力平衡孔,车外侧胶条空腔的侧壁向胶条空腔侧内凹,且在车外负压工况下保持内凹趋势;车外侧胶条空腔侧壁和车内侧胶条空腔侧壁具有交汇部;交汇部远离胶条空腔的一侧设有外密封唇和内密封唇;密封主体包括连接在锚点安装部和车外侧胶条空腔侧壁之间的倚靠臂,倚靠臂和车外侧胶条空腔侧壁的交点位于交汇部与依靠臂垂线远离锚点安装部的一侧。本申请提供了一种关门时胶条反弹力较小的、且车门负压工况下较小的初始压缩量也能具有良好动态密封性能的密封胶条。
