A vehicle body anti-collision structure, which is mounted within a vehicle body covering and used for buffering an impact force applied to a vehicle body, the structure having two buffering frames capable of buffering the applied impact force and a connecting frame, wherein the connecting frame is disposed at the bottom end of the vehicle body and fixed to a chassis of the vehicle body, and the two buffering frames are respectively disposed at the front end and rear end of the vehicle body and are fixed to both ends of the connecting frame. The above-mentioned vehicle body anti-collision structure is of an overall structure, such that when the buffering frames at the front and rear of the vehicle body are impacted, the impact force will be dispersed to the whole vehicle body anti-collision structure and the chassis, instead of being completely withstood by themselves, so that a greater impact force can be withstood, improving the safety of the vehicle body.

An electrically driven vehicle comprises: a body frame arranged in a holding compartment formed in front of a passenger compartment; a suspension member fastened to the body frame in the holding compartment through a rear side fastening structure; and a fuel cell stack supported on the suspension member through a rear side mount at a position in front of the rear side fastening structure. When a serious collision occurs, the fuel cell stack moves rearward and strikes the fastening structure whereby the fastening structure breaks and thereby suspension member separates from the body frame and the fuel cell stack moves downward and heads toward the inside of the shelter space between the holding compartment and a road surface.

The present invention provides for an improved air tank cross member deployable in a vehicle chassis. The ATCM comprises one or more structural elements comprising a tube forming an enclosure for holding a compressed fluid and having mounting extensions on an outer surface of the tube. The structural elements comprise two or more brackets connected to the mounting extensions of the tube and a pair of end caps disposed at opposite ends of the tube for forming the enclosure. The brackets are attached to the end caps by a fastening means to form a unified mounting geometry. The arrangement and construction of the structural elements of the ATCM provide for space-saving and weight-saving and increases stiffness value of one or more stiffness parameters of the vehicle chassis.
