The invention relates to a motorcycle carriage structure which comprises a carriage body, a cushion, a fixed seat, a movable part, a torsion spring and a damping spring, an opening is formed in the top of the carriage body, the cushion covers the opening, the fixed seat is arranged in the carriage body, and the movable part is connected with the cushion and pivoted with the fixed seat through a rotating shaft to have an opening stroke. The torsion spring is arranged on the rotating shaft in a sleeving mode and abuts against the fixed seat and the movable part, so that the movable part turns over along the opening stroke to lift the cushion, the damping spring reversely abuts against the movable part and the fixed seat along the opening stroke, and the elastic coefficient of the damping spring is smaller than that of the torsion spring; therefore, the opening speed of the motorcycle cushion can be slowed down, and the cushion is prevented from shaking or hurting an operator due to acting force after being bounced off.

    本发明关于一种摩托车车厢结构,包括厢体、坐垫、固定座、活动件、扭力弹簧及阻尼弹簧,厢体的顶部具有开口,坐垫罩盖开口,固定座设置在厢体,活动件连接坐垫并以转轴枢接固定座而具有开启行程,扭力弹簧套设在转轴且分别抵接固定座及活动件,从而使活动件沿开启行程翻转以抬升坐垫,阻尼弹簧沿开启行程反向推抵活动件及固定座,阻尼弹簧的弹性系数小于扭力弹簧的弹性系数;借此,可减缓摩托车坐垫的开启速度,避免坐垫在弹开后受到作用力而晃动或是弹伤操作者。
