The invention belongs to the field of auxiliary transportation devices for underground coal mines and particularly relates to a light mine explosion-proof electric vehicle. The light mine explosion-proof electric vehicle aims at solving the problem that no small flexible pollution-free explosion-proof electric vehicle for an underground coal mine exists at preset. A chassis body is of an integrated structure formed by welding steel plates and profile steel in an overlap joint manner. A motor transmission system comprises an explosion-proof motor, a differential speed reduction gearbox, a short transmission half shaft of a spherical cage structure, a long transmission half shaft of a spherical cage structure, a front left wet-type multi-disc brake and a front right wet-type multi-disc brake. A front independent suspension system structurally comprises a left shock absorber, a left swing arm and a left stabilizing rod and a rear independent suspension system structurally comprises a right shock absorber, a right swing arm and a right stabilizing rod. The left angle of elevation and the right angle of elevation are provided with shock absorber connection points, stabilizing rod connection points and swing arm connection points respectively. On the premise that the structural strength requirement is met, the lightweight design is adopted, the mass of the whole vehicle is reduced as much as possible, and the light mine explosion-proof electric vehicle has the beneficial effects of being low in mass, small in shape size, compact in structure, flexible and efficient in mechanic operation, free of pollution and the like and is mainly used for the fields of rescue, overhauling, inspection and the like of the underground coal mines.
