The utility model relates to a brake disc structure with ventilation inside and outside. The brake disc structure comprises a first friction disc (1), a second friction disc (2) and a disc cap (3), the first friction disc (1) is connected with the disc cap (3), and the second friction disc (2) is annularly arranged on the outer side of the disc cap (3) and connected with the first friction disc (1) through the ventilation ribs (4). A ventilation channel (5) is arranged between every two adjacent ventilation ribs (4), the ventilation ribs (4) and the ventilation channels (5) extend to the plate cap (3), and plate cap ventilation holes (6) used for communicating the ventilation channels (5) with the inner side of the plate cap (3) are formed in the plate cap (3). Compared with the prior art, on the basis of the external ventilation disc, the ventilation ribs and the ventilation channels are extended to the disc cap, so that the brake disc has better structural strength, the thermal deformation resistance is enh
