The invention relates to a light-weight vehicle door internal supporting and reinforcing structure, a design method and a vehicle, and belongs to the technical field of vehicles, the light-weight vehicle door internal supporting and reinforcing structure comprises a vehicle door body, the vehicle door body comprises a vehicle door inner plate and a vehicle door outer plate, and the vehicle door inner plate is provided with lightening holes; a supporting piece which extends in the direction of the automobile door outer plate and is used for supporting the automobile door outer plate is integrally formed on the edge of the lightening hole in a punching mode. Therefore, the vehicle door outer plate is supported and reinforced through the supporting piece, light weight and low cost of the white vehicle body door are achieved, and meanwhile the concave resistance of the white vehicle body door is met. Under the condition that the concave resistance of the vehicle door is guaranteed, supporting stiffening beams in the vehicle door can be reduced or completely omitted, the number of parts of the vehicle door is reduced, and the weight of the vehicle door is reduced. Meanwhile, the production material cost and the production manufacturing cost of the vehicle door can be reduced, procedures are reduced, the production efficiency is high, and the advantages of light weight and cost are achieved.
