The invention relates to a seat cushion rigidity adjusting mechanism and a seat device, the seat cushion rigidity adjusting mechanism comprises a mounting plate, a rotating shaft and a cam, and the mounting plate is used for being mounted below a seat; the rotating shaft is rotationally connected to the mounting plate; the cam is arranged on the rotating shaft in a sleeving mode and used for being attached to the lower surface of the seat, and the rotating shaft can rotate and drive the cam to rotate synchronously, so that the cam extrudes the lower surface, and the anti-diving degree of the seat is adjusted. According to the rigidity adjusting mechanism for the seat cushion, when the rotating shaft drives the cam to synchronously rotate, the cam can extrude the sponge of the seat, so that the anti-diving degree of the seat is adjusted, the rigidity of the seat is adjusted, and the elastic deformation resisting capacity of the seat when the seat is stressed is adjusted. According to the rigidity adjusting mechanism for the seat cushion, the seat is extruded through rotation of the cam, the rigidity of the seat cushion is adjusted, and the rigidity of the corresponding seat cushion is adjusted by rotating the cam by a specific angle corresponding to different working conditions.
本发明涉及一种座椅椅垫刚度调节机构及座椅装置,座椅椅垫刚度调节机构包括安装板、转轴以及凸轮,安装板用于安装在座椅的下方;转轴转动连接于安装板;凸轮套设在转轴上,且凸轮用于贴合于座椅的下表面,转轴能够转动并带动凸轮同步转动,以使凸轮挤压下表面,调节座椅的防下潜程度。上述座椅椅垫刚度调节机构,当转轴带动凸轮同步转动时,凸轮能够挤压座椅的海绵,从而调节了座椅的防下潜的程度,调节了座椅的刚度,即调节了座椅在受力时抵抗弹性变形的能力。本发明提供的座椅椅垫刚度调节机构,通过凸轮转动从而挤压座椅,调节了座椅椅垫的刚度,对应不同的工况,凸轮转动特定的角度,调节对应的座椅椅垫的刚度。
