The invention provides an extensible vehicle emergency floating device, and belongs to the technical field of vehicle emergency rescue devices. Comprising a connecting frame component, a double-linkage air bag assembly, a compression air supply assembly and an extension driving assembly and is connected with a chassis of an automobile through a connecting piece, a plurality of sets of pressure sensing modules are installed on a left frame body and a right frame body of a square frame, and after the automobile falls into water, an air tank valve and an air driving valve which are connected outside a compression air tank can be opened through signal output of the pressure sensing modules; compressed air quickly enters an air-driven cavity to drive a spiral wheel and a pneumatic bevel gear to rotate, so that a lead screw bevel gear and a bidirectional lead screw can be driven to rotate, two groups of inner connecting plates drive correspondingly connected floating air bags to outwards extend and move to a set position, and then an air bag valve is opened; compressed air rapidly enters the floating air bag to be rapidly inflated, and the stability of emergency floating support can be greatly improved by enlarging the supporting area of the floating air bag relative to an automobile.

    本发明提供一种可伸展的交通工具应急漂浮装置,属于交通工具应急救援装置技术领域。包括联架构件、双联动气囊总成、压缩供气总成、伸出驱动总成,通过连接件与汽车的底盘连接,方架的左右框体上安装有数组压力传感模块,在汽车落水后,通过压力传感模块的信号输出,可打开连接在压缩气罐外的气罐阀与气驱阀,使得压缩气体快速进入到气驱腔内带动螺旋轮及气动锥齿轮的旋转,从而可带动丝杠锥齿轮及双向丝杠的旋转,使得两组内连接板带动对应连接的漂浮气囊向外伸展移动到设定位置,随后打开气囊阀,使得压缩气体快速进入到漂浮气囊进行快速的充气,通过扩大漂浮气囊相对于汽车的支撑面积的方式,可大大提高应急漂浮支撑的稳定性。
