The invention discloses a folding child scooter with high reliability. The folding child scooter comprises a pedal, and a second rolling wheel is rotationally arranged at the bottom of the pedal; a brake assembly is arranged on one side of the second roller; a rotating cylinder is rotationally arranged at the bottom of the pedal; a resistance piece is fixedly connected in the rotating cylinder in the radial direction; and a conductive slip sheet is in sliding fit with the resistance piece. When the running speed of the scooter is larger than the speed limiting threshold value of the scooter, the conductive sliding piece moves along the electric assembly under the action of centrifugal force, resistance in a circuit is reduced, current is increased, and therefore the acting force of the electromagnet on the friction plate is increased, the friction plate gradually gets close to the brake pad, pressure is applied to the brake pad, and the scooter is driven to run. The friction force between the friction plate and the brake pad is increased, rotation of the second rolling wheel is hindered, the running speed of the scooter is reduced, and then the speed limiting purpose of the scooter is achieved. The speed limit threshold value of the scooter can be adjusted by adjusting the position of the conductive slip sheet on the resistor piece.

    本发明公开了一种可靠性高的折叠式儿童滑板车,包括踏板,所述踏板的底部转动设有第二滚轮;所述第二滚轮的一侧设有刹车组件;所述踏板的底部转动设置有旋转筒;所述旋转筒内径向固定连接有电阻件;所述电阻件上滑动配合有导电滑片。当该滑板车的行驶速度大于该滑板车的限速阈值时,导电滑片在离心力的作用下,沿着电组件移动,使电路中的电阻减小,电流增大,从而使电磁铁对摩擦板的作用力增大,使摩擦板逐渐靠近刹车片,并对刹车片施加压力,使摩擦板与刹车片的摩擦力增大,阻碍第二滚轮的转动,使该滑板车的行驶速度降低,进而达到对该滑板车限速的目的。通过调节导电滑片在电阻件上的位置,可以调节该滑板车的限速阈值。
