NOVELTY - The structure has a vehicle seat compartment (1) that is fixedly arranged on a vehicle frame, and a placement cavity is opened in the vehicle seat compartment. A safety compartment (2) is matched with the placement cavity is detachably installed in the placement cavity, and a battery (3) is movable in the safety compartment. A hollow groove is opened in the side wall of the safety chamber, and a sealing baffle slides up and down in the hollow groove. The radiating blades are rotatably installed on the cooling disc, and the rotating shaft (51) of the cooling blades meshes with the second end face gear (54) through a bevel gear structure. The second end gear is meshed with a turntable, the turntable is installed at one end of the shaft, and the other end of the shaft is engaged with the first end face gear (53) through another turntable. The first end face gear is coaxially and fixedly connected to the rotation shaft of the pedal gear. USE - Graphene battery installation structure for hand-held detachable battery car. ADVANTAGE - The thermal fuse is blown first when the battery catches fire due to a short circuit, and the sealing baffles in the safety chamber slide downwards to seal the safety chamber, and the flames in the safety chamber is automatically extinguished due to lack of oxygen. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene battery installation structure for hand-held detachable battery car. 1Vehicle seat compartment 2Safety compartment 3Battery 4Movable pin structure 5Active radiating mechanism 51Rotating shaft 52Rotating plate 53First end face gear 54Second end face gear 55Bevel gear structure 102Ventilation groove 208Baffle 5201Rotating wheel
