The invention relates to a top cover assembly of a vehicle, a body-in-white structure of the vehicle and the vehicle. The top cover assembly of the vehicle comprises a top cover outer plate and a top cover beam structure, the top cover beam structure is symmetrical about a reference plane and arranged on one side of the top cover outer plate, the top cover beam structure comprises a first top beam set and a second top beam set which are each provided with a plurality of top beams, and the top beam end of the first top beam set is provided with a turnover connecting part; the top beams of every two adjacent first top beam sets are connected through a turnover connecting part, the top beams of the first top beam sets are manufactured through the rolling technology, and the top beams of the second top beam sets are manufactured through the stamping technology. The top cover beam structure of the top cover assembly is machined and manufactured by adopting a roller punching composite scheme, different top beam machining processes can be reasonably selected according to the stress conditions of different positions of the top cover beam structure in practical application, and the reasonability of the top cover beam structure design can be improved; the structural strength of the top cover beam structure is guaranteed, and meanwhile the top cover beam structure can be light in weight.
