The invention discloses a middle hydrogen bottle fixing device for a hydrogen fuel cell vehicle, which comprises a plurality of first limiting rings which are arranged side by side along the axial direction of a hydrogen bottle and are used for limiting bottle bodies of horizontal hydrogen bottles, first mounting frames are fixed at the upper ends of the first limiting rings, and the adjacent first mounting frames are fixedly connected through first connecting pieces; a mounting hole used for being fixedly connected with a frame cross beam of the hydrogen fuel cell automobile is formed in the first mounting frame, and the first limiting ring is used for hoisting a hydrogen cylinder on the frame cross beam; the hydrogen bottle further comprises a second limiting ring used for limiting the bottle head and the bottle tail of the hydrogen bottle, and the upper end of the second limiting ring is fixedly connected with the first installation frame on the corresponding side through a second connecting piece. The hydrogen bottle fixing device is small in overall size, light in weight and small in occupied space, the hydrogen bottle is arranged in the middle of the vehicle frame in a hoisting mode, the space in the middle of the vehicle frame can be fully utilized, and the two second limiting rings can prevent the hydrogen bottle from axially moving due to inertia.
本发明公开了一种用于氢燃料电池汽车的中间氢瓶固定装置,包括多个沿氢瓶轴向并排布置并用于对横卧的氢瓶瓶身限位的第一限位环,第一限位环上端固定有第一安装架,相邻第一安装架之间通过第一连接件固定连接,第一安装架上设有用于与氢燃料电池汽车的车架横梁固定连接的安装孔,第一限位环用于将氢瓶吊装于车架横梁上;还包括用于对氢瓶的瓶头和瓶尾限位的第二限位环,第二限位环上端通过第二连接件与相应侧第一安装架固定连接。本氢瓶固定装置的整体尺寸小且重量小,并且占用空间小,而且本中间氢瓶固定装置采用吊装的方式将氢瓶设置于车架中间,能充分利用车架中间的空间,并且两个第二限位环能防止氢瓶由于惯性导致的轴向窜动。
