[0003] A Chinese utility model patent with the publication number CN203469302U discloses a sports training buffer pad, which includes two layers of sponge boards, a buffer layer, and a pad cover. The buffer layer includes two fixed plates, springs and fillers, wherein two layers of sponge There are two fixed plates fixed between the two fixed plates, counterbore holes are evenly distributed on the opposite surfaces of the two fixed plates, the springs cooperate with the counterbore holes on the opposite surfaces of the two fixed plates, and the filling is a sponge plate, and through holes are uniformly distributed on the sponge plates , the evenly distributed through holes on the sponge board match the outer diameter of the spring, and the two sides of the sponge board cooperate with the fixed plate to form a sports training cushion. The cushion is placed in the cushion cover, and there is a handle on the cushion cover. When cushioning, the spring in the cushioning layer releases force, and the cushioning effect is good, and the two ends and the outer diameter of the spring cooperate with the evenly distributed counterbore holes on the fixed plate and the evenly distributed through holes on the filled sponge plate, so that the sports training cushion pad The overall effect is good; but its structure is simple, the cushioning performance is not good, accidents may occur after long-term use, and because the existing protective pad body and the mounting seat at the bottom are often large in size, relatively heavy, and inconvenient to carry, Moreover, it is difficult to disassemble the upper protective pad body, which is not conducive to use and needs to be improved
