The invention relates to a bicycle lifting seat tube which comprises a seat cushion connecting piece, a seat tube head, an outer tube and a lifting assembly, the lifting assembly comprises an air pressure rod and a motor, the air pressure rod is inversely arranged in the outer tube in a sleeved mode, the motor is installed at the lower end of the outer tube, and the output end of the motor is connected with the piston end of the air pressure rod. And the cylinder body end of the air pressure rod is connected with the seat cushion connecting piece through the seat tube head. The motor is used for driving the inverted air pressure rod piston end to stretch out and draw back, so that the air pressure rod piston end moves along the outer pipe, then the seat pipe head is driven to ascend and descend, manual seat cushion ascending and descending are not needed, hydraulic ascending and descending are avoided, the ascending and descending structure is simpler and more flexible, part cost is low, and the good application effect is achieved.
本发明涉及一种自行车升降座管,包括座垫连接件,座管头,外管与升降组件,所述升降组件包括气压棒与电机,所述气压棒倒装套设在外管内,所述电机安装在外管下端,其输出端与气压棒的活塞端与连接,所述气压棒缸体端通过座管头与座垫连接件连接。使用电机带动倒装的气压棒活塞端伸缩,使其沿着外管运动,进而带动座管头升降,无需人工升降座垫,且避免使用液压升降,升降结构更加简洁,灵活,且零件成本低,具有极好应用效果。
