Referring to fig. 6-7, a movable slot is provided in the middle baffle 71, a warning block 722 made of an elastic material is installed in the movable slot, pigment coatings are coated on two side surfaces of the warning block 722, traction cables 721 penetrating and sliding in the movable slot are connected to two side surfaces of the warning block 722, and ends of the traction cables 721 are connected to surfaces of the rolling warning rods 72.
Specifically, when the surface of the battery assembly is partially raised and the rolling warning rod 72 is inclined and falls, the warning block 722 is pulled to generate lateral bending deflection under the action of the traction inhaul cable 721, so that the warning block 722 is close to the side surface with the partial raised surface and the partial raised condition of the surface of the battery assembly can be judged through the exposed color coating.
