The invention discloses a cushion adjusting mechanism which is characterized in that a cushion assembly is supported on a first hydraulic assembly below the cushion assembly, the first hydraulic assembly is arranged in a saddle supporting sleeve, and the saddle supporting sleeve is a part of a frame; a first hydraulic oil cavity in the first hydraulic assembly communicates with a second hydraulic oil cavity in the second hydraulic assembly through the valve set, the second hydraulic assembly is arranged behind the cushion assembly and located above the rear wheel assembly, and when the valve set is opened, external force acts downwards to drive the cushion assembly to move downwards. Hydraulic oil in the first hydraulic oil cavity enters the second hydraulic oil cavity, so that the rear wheel shaft is driven to move upwards and forwards; when the valve bank is opened, the cushion assembly can move upwards without external force, and hydraulic oil in the second hydraulic oil cavity enters the first hydraulic oil cavity, so that the rear wheel shaft is driven to move downwards and backwards. The electric bicycle has the advantages of being simple and ingenious in structure, quite rapid and convenient to adjust, good in anti-seismic performance and high in riding comfort.
本发明公开了一种坐垫调节机构,坐垫组件支撑在其下方的第一液压组件上,第一液压组件设置在车座支撑套管中,车座支撑套管为车架的一部分;第一液压组件中的第一液压油腔通过阀组与第二液压组件中的第二液压油腔连通,第二液压组件设置在坐垫组件的后方且位于后车轮组件的上方,阀组开阀时,外力向下作用能驱使坐垫组件向下运动,从而使得第一液压油腔中的液压油进入第二液压油腔,从而驱使后车轮轴向上并向前运动;阀组开阀时,坐垫组件在没有外力作用能向上运动,第二液压油腔中液压油进入第一液压油腔中,从而驱使后车轮轴向下并向后运动。本发明的优点在于:结构简单巧妙,调节十分快速方便,抗震性能好,骑行舒适度高。
