The invention discloses a child electric scooter with a variable speed adjusting mechanism, which comprises a shell and a rear wheel, and a driving piece is fixedly mounted on the inner surface wall of the shell. According to the device, a user can step on a driving handle, the outer surface wall of a linkage sleeve can be screwed with the inner surface wall of a pushing sleeve in a threaded mode, the pushing sleeve can longitudinally push a matching seat under limiting of a first telescopic rod, the matching seat slides along a shaft rod and pushes multiple sets of push rods, and the two ends of the multiple sets of push rods can move with a second telescopic rod and the matching seat at the same time; the driving part can drive the driving wheel through the shaft rod and push the wheel petals forming the driving wheel to expand, so that the inner diameter of the driving wheel is expanded, and at the moment, the driving part can also drive the driving wheel through the shaft rod and enable the matching seat to synchronously rotate with the driving wheel through matching of the embedded block and the clamping groove; therefore, variable-speed adjustment of the scooter body is achieved, and the application range of the electric scooter for children is widened.
本发明公开了一种带有变速调节机构的儿童电动代步车,包括壳体与后轮,所述壳体内表壁固定安装有驱动件。本发明中,使用者可通过踩压驱动柄,联动套外表壁会与推动套内表壁螺纹旋合,推动套会在伸缩杆一的限位下纵向推动配合座,配合座沿着轴杆滑动并推动多组推杆,多组推杆的两端会同时与伸缩杆二与配合座相活动,并推动组成主动轮的各个轮瓣扩张,使得主动轮内径扩张,此时驱动件同样可以通过轴杆驱动主动轮以及通过嵌块与卡槽的配合使得配合座同步主动轮进行转动,但是由于主动轮内径变化而使得后轮转速发生变化,进而实现车体的变速调节,从而提高了儿童电动代步车的适用范围。
