The invention relates to the technical field of electric bicycles, and particularly discloses a transmission mechanism for saddle lifting adjustment of an electric bicycle. The transmission mechanismcomprises a bicycle body and a saddle, a vertical cylinder is fixed to the upper surface of the bicycle body, a screw sleeve sliding cavity is formed in the lower end of the vertical cylinder, a through hole communicating with the screw sleeve sliding cavity is formed in the upper end of the vertical cylinder, and the lower end of the saddle is connected with a hollow inserting rod capable of penetrating through the through hole to extend into the screw sleeve sliding cavity, the lower end of the hollow inserting rod is connected with a screw sleeve, a worm is rotationally arranged at the lower left end of the vehicle body, one end of the worm is connected with an extension rod, and the extension rod is connected with a bidirectional ratchet wheel assembly. According to the transmission mechanism for saddle lifting adjustment, the screw rod can rotate through the transmission effect among the ratchet wheel, the pawl, the worm wheel, the worm, the horizontal rotating rod, the vertical rotating rod and the bevel gear, then the height of the saddle is adjusted through the effect between the screw rod and the screw sleeve; and the whole adjusting process is comfortable, convenient andfast.

    本发明涉及电动自行车技术领域,具体公开了一种用于电动自行车鞍座升降调节的传动机构;包括车体和鞍座,车体的上表面固定有立筒,立筒的下端开设有丝套滑动腔,立筒的上端开设有与丝套滑动腔相连通的通孔,鞍座的下端连接有能够穿过通孔伸入丝套滑动腔中的空心插杆,空心插杆的下端连接有丝套,车体的左下端转动设置有蜗杆,蜗杆的一端连接有延伸杆,延伸杆上连接有双向棘轮组件;本发明公开的鞍座升降调节的传动机构其通过棘轮、棘爪、蜗轮、蜗杆、水平转杆、竖向转杆、锥形齿轮之间的传动作用能够使得丝杆转动,再通过丝杆与丝套之间的作用实现对鞍座的高度调节,其整个调节过程舒适、方便、快捷。
