The invention relates to the field of automobile braking, in particular to a breathable waterproof structure and a braking system box using the same. The breathable waterproof structure comprises a breathable hole formed in a base material, a circle of protruding edge surrounding the breathable hole on the base material and a waterproof breathable film welded to the base material in an ultrasonic mode, and the position of the protruding edge is covered with the welding area of the waterproof breathable film and the base material. The waterproof breathable film with the breathable waterproof structure and the base material are welded through ultrasonic waves, so that the water pressure resistance is improved. Secondly, a circle of protruding edge within the coverage range of the welding area is arranged, heat is concentrated at the position of the protruding edge during ultrasonic welding due to the arrangement of the protruding edge, a circle of connecting structure which is connected more tightly can be formed when the melted material is combined with the waterproof breathable film, and the water pressure resistance can be improved to 70 kpa or above from 50 kpa of conventional ultrasonic welding.

    本申请涉及汽车制动的领域,尤其是涉及一种透气防水结构及使用该结构的制动系统盒。一种透气防水结构,设置在基材上的透气孔、基材上围绕透气孔一圈的凸沿,以及与基材超声波焊接的防水透气膜,所述防水透气膜与基材的焊接区域覆盖凸沿的位置。设置透气防水结构的防水透气膜跟基材之间是通过超声波焊接来提升抗水压能力。其次设置一圈在焊接区覆盖范围内的凸沿,凸沿的设置使得超声波焊接时在凸沿位置热量集中,且熔化后的材料与防水透气膜结合时能够形成一圈连接更为紧密的连接结构,使得抗水压能力能够从常规超声波焊接的50kpa提升至70kpa以上。
