The invention provides a battery mounting structure, which comprises a battery, a mounting frame, a pressing mechanism, a lifting mechanism and two fixing plates arranged opposite to each other. The mounting frame is provided with an accommodating space for accommodating the battery. Two ends of the pressing mechanism are respectively connected with two sides of the mounting frame to press the battery in the accommodating space. The fixing plate is provided with a fixing flange for connecting with the mounting bracket and a mounting flange for connecting with the vehicle frame; The fixing flange is of inverted L-shaped structure, and the fixing flange has a limiting surface for stopping and connecting with the pressing mechanism; The lifting mechanism is connected with the fixing plate, the lifting mechanism is provided with a connecting piece connected with the pressing mechanism, and the lifting mechanism drives the battery to be lifted or lowered through the connecting piece; The fixed flange is removably connected to the mounting bracket. The battery mounting structure of the invention can make the repair and maintenance of the battery more convenient, and can effectively solvethe problem that the battery falls to the ground and is damaged due to misoperation, and the operator is injured.
