The invention discloses a motorcycle seat cushion hinge structure which comprises a hinge shaft, a torsion spring, an upper mounting plate, a lower mounting plate, a hook, an extrusion sheet and a groove plate, the upper mounting plate and the lower mounting plate are rotationally connected through the hinge shaft, the upper mounting plate is fixedly connected with a bottom plate of a seat cushion, the lower mounting plate is fixedly connected with a seat box, and the torsion spring is arranged on the hinge shaft in a sleeving mode; the upper end of the hook is fixedly connected with the upper mounting plate; the extrusion sheet is arranged on the outer side of the hook and is fixedly connected with the seat box; the groove plate is rotationally connected with the hinge shaft and located above the lower mounting plate, a torsion rod at one end of the torsion spring abuts against the lower surface of the upper mounting plate, and a torsion rod at the other end of the torsion spring abuts against the upper surface of the groove plate; positioning grooves are formed in the left side and the right side of the groove plate; when the hinge mechanism is closed, the hook is squeezed by the squeezing piece to be buckled into the positioning groove. The elastic force of the torsion spring cannot continuously act on the seat cushion bottom plate, and the phenomenon that water enters the helmet box due to deformation of the seat cushion bottom plate is fundamentally avoided.

    本发明公开了一种摩托车座垫铰链结构,其包括铰链轴、扭簧、上安装板、下安装板、挂钩、挤压片和沟槽板,上安装板与下安装板通过铰链轴实现转动连接,上安装板与座垫的底板固定连接,下安装板与座箱固定连接,扭簧套设在铰链轴上;挂钩的上端与上安装板固定连接;挤压片设置在挂钩的外侧且与座箱固定连接;沟槽板与铰链轴转动连接且位于下安装板的上方,扭簧的一端扭杆与上安装板的下表面相抵,扭簧的另一端扭杆与沟槽板的上表面相抵;沟槽板的左右两侧均设有定位沟槽;铰链机构闭合时,挂钩被挤压片挤压扣入定位沟槽内。本发明能够使扭簧的弹力无法持续作用在座垫底板上,从根本上避免了因座垫底板变形而引起头盔箱进水的现象。
