The invention discloses an automobile top cover structure which comprises a top cover, a first beam, a second beam, a third beam and a fourth beam. The first beam, the second beam, the third beam and the fourth beam each comprise a first groove, a second groove, a third groove, a fourth groove and a fifth groove. The width of each first groove, the width of each second groove, the width of each third groove, the width of each fourth groove and the width of each fifth groove form a geometric sequence with the common ratio equal to p. Each third groove comprises a first round hole, second round holes, third round holes and fourth round holes, wherein the second round holes, the third round holes and the fourth round holes are symmetrically distributed in the two sides of the first round hole. The diameter of each fourth round hole, the diameter of each third round hole, the diameter of each second round hole and the diameter of each first round hole form a geometric sequence with the common ratio equal to q. The automobile top cover structure is low in mass and capable of effectively preventing resonance, and greatly improves the safety performance and the NVH performance of an automobile body.
