The invention discloses a centrifugal speed-limiting skateboard for children. The skateboard comprises a skateboard body, a hand lever, gravity steering wheels and a centrifugal speed-limiting mechanism, a hand lever used for hand holding is fixedly arranged at one end of the upper portion of the skateboard body, and the gravity steering wheels are arranged at the two ends of the lower portion ofthe skateboard body respectively. The centrifugal speed limiting mechanism used for limiting the speed of the sliding plate is arranged between the two gravity steering wheels on the lower portion ofthe sliding plate body, the fixing base is fixed to the lower portion of the sliding plate body through screws, one end of the rocker arm is arranged on the fixing base through a pin shaft, and a speed limiting wheel base is fixedly arranged at the other end of the rocker arm. A speed limiting wheel shaft is arranged on the speed limiting wheel base, a driven friction plate matched with the centrifugal driving friction mechanism to increase the sliding resistance of the sliding plate is arranged at the lower part of the sliding plate body. When the skateboard slides at a high speed, the sliding resistance is increased, so that the speed of the skateboard is controlled within a certain speed range, the safety of children is improved, and meanwhile, the use of the skateboard is not influenced by resistance within a reasonable speed range.
本发明公开了一种离心式限速儿童滑板,包括滑板板体、手扶杆、重力转向轮和离心限速机构,滑板板体上部一端固设有用于手扶的手扶杆,滑板板体下部两端分别设置有重力转向轮,滑板板体下部两个重力转向轮之间设置有用于限制滑板速度的离心限速机构,固定座通过螺钉固定在滑板板体下部,摇臂一端通过销轴设置在固定座上,另一端固设有限速轮座,限速轮座上设置有限速轮轴,滑板板体下部设置有与离心主动摩擦机构配合增加滑板滑动阻力的被动摩擦板。本发明能够使滑板在较快的速度滑行时,增大滑行的阻力,从而使滑板速度控制在一定的速度范围内,有利于提高儿童的安全性,同时合理速度范围内,不会对滑板使用有阻力影响。
