The invention discloses a steel keel hole plate blank and fiberglass solar air guide and boosting carriage. The steel keel hole plate blank and fiberglass solar air guide and boosting carriage comprises a housing, an exhaust fan and an air guide pipeline; solar cell panels are mounted on the top, the left side and the right side of the housing to collect solar for supplying power to the exhaust fan to absorb air from the front and exhaust the air from the back, so as to provide boosting force to a vehicle; the carriage is firm, wearable and free of rust; the solar is fully utilized, so that the energy is saved, the emission is reduced, the green and environmental protection are achieved; door and window are arranged at the back, so that the passageway is not used when passengers getting on or off the vehicle; a small space is needed for parking; people can get off when the vehicle is stopped; therefore, the problem that the vehicle with door opened leftwards and rightwards is parked and people cannot get off can be avoided.
