The invention relates to the technical field of vehicle cross beams, in particular to an airbag cross beam device comprising an inflation and deflation mechanism, an air bag body and bendable cross beam assemblies connected to the two ends of the air bag body. The inflation and deflation mechanism is communicated with the air bag body and enables the air bag body to be inflated or deflated, so that the air bag body drives the two ends of the bendable cross beam assemblies to get away from each other or get close to each other by a preset distance. The airbag cross beam device is different froman existing cross beam which is always connected with a frame of a vehicle frame, the bendable cross beams of the airbag cross beam device can extend or shorten by a preset distance, and a structuralbasis is provided for the vehicle frame to change torsional rigidity according to road conditions.

    本发明涉及车辆横梁技术领域,尤其涉及一种气囊横梁装置。该气囊横梁装置包括充放气机构、气囊本体和连接于气囊本体两端的可弯曲横梁组件;充放气机构与气囊本体相连通并能够使气囊本体充气或放气,以使气囊本体带动可弯曲横梁组件的两端互相远离或互相靠近预定距离。该气囊横梁装置区别于现有的始终与车架的框架相连接的横梁,该气囊横梁装置的可弯曲横梁能够伸长或缩短预定距离,并为车架实现根据路况改变扭转刚度提供结构基础。
