[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0028] Embodiment 1

[0029] like Figure 1 As shown, a high-rebound saddle cushion provided in this embodiment includes a cushion body 100, the head 110 of the cushion body 100 is used to support the crotch of the human body, the tail 120 of the cushion body 100 is used to support the buttocks of the human body, slow-rebound parts 130 are provided on both sides of the tail 120 of the cushion body 100, and an air hole 140 is provided in the middle where the head 110 and the tail 120 of the cushion body 100 are connected; wherein the cushion body 100 is made of high-rebound foam material, such as soft foam polyether; the slow-rebound part 130 can be made of high-density memory cotton.

[0030] Specifically, when the saddle pad is in use, the seat cushion body 100 may collapse due to the long-term pressure from the human buttocks. If the seat cushion body 100 is designed to be made of high-rebound material throughout, the production cost will be high. Therefore, the saddle pad of this embodiment is filled with a slow-rebound part 130 at the tail 120 of the high-rebound seat cushion body 100. The slow-rebound part 130 adopts a low-cost chronic rebound material such as high-density memory foam. On the one hand, it can avoid the problem of the tail 120 of the seat cushion body 100 collapsing under force, and on the other hand, it can also reduce the production cost. At the same time, it can also improve the comfort of the human buttocks when riding.

[0032] Specifically, when the upper mold base 220 is rotated to close the mold with the lower mold base 210, the cavity between the concave mold cavity 211 and the convex mold core 221 can be molded into the seat cushion body 100 after the high-resilience foam material of the fluid is injected. At this time, the air vent core 212 is in contact with the surface of the convex mold core 221, and the air vent 140 is formed on the seat cushion body 100 after the high-resilience foam material is condensed. The rebound part core 230 is in contact with the inner wall of the concave mold cavity 211, and the high-resilience foam material is condensed to form a cavity of the slow rebound part 130 at the tail 120 of the seat cushion body 100, and the seat cushion body 100 is obtained. Figure 2 The seat cushion body shown in the figure is then filled with high-density memory foam of a fluid into the cavity of the slow-rebound portion 130 , and after condensation, the high-rebound saddle cushion of this embodiment can be obtained.
