The invention relates to an external drainage system of a commercial vehicle cab, and belongs to the technical field of commercial vehicle cabs. Comprising a cab and a cab top cover connected to the top of the cab, and a top cover side wall of the cab top cover is connected with a side wall metal plate of the cab in a welded mode to form a welding spigot edge protruding out of the cab; the rainwater guide groove comprises a side top decoration strip covering the welding spigot edge, sealing foam is connected between the side top decoration strip and the welding spigot edge, and the side top decoration strip, the sealing foam, the welding spigot edge and the top cover side wall jointly form the rainwater guide groove with the top open. The rainwater guide groove prevents water flow on the cab top cover from flowing downwards, the water flow is guided to the front of the cab to be discharged towards the A column in the cavity formed by the side top decoration strip and the top cover side wall, and the situation that a large amount of rainwater passes through a door frame outer sealing strip when flowing downwards along a metal plate in a traditional scheme is avoided; and the waterproof pressure and the design difficulty of the door frame outer sealing strip are reduced.
本申请涉及一种商用车驾驶室外部排水系统,属于商用车驾驶室技术领域。包括:包括驾驶室和连接在驾驶室顶部的驾驶室顶盖,驾驶室顶盖的顶盖侧围与驾驶室的侧围钣金相互焊接连接且形成凸出于驾驶室外部的焊接止口边;雨水导流槽,该雨水导流槽包括覆盖焊接止口边的侧顶装饰条,侧顶装饰条与焊接止口边之间连接有密封泡棉,侧顶装饰条、密封泡棉、焊接止口边和顶盖侧围共同形成顶部敞口的雨水导流槽。本申请的雨水导流槽阻绝驾驶室顶盖上水流向下流动,在侧顶装饰条和顶盖侧围形成的空腔中,将水流引导至驾驶室前方向A柱排出,避免了传统方案大量雨水顺钣金向下流动时经过门框外密封条的情形,降低了门框外密封条的防水压力及其设计难度。
