The invention relates to children's bicycles, in particular to an adjustable active speed-limiting children's bicycle. Comprising a child bicycle body, a rotating disc, a fixing shell, a clamping ring, rotating hook plates, friction blocks and the like, the rotating disc is connected to a rear wheel rotating shaft of the child bicycle body, the fixing shell is connected to the child bicycle body, the clamping ring is rotationally connected into the fixing shell, the two rotating hook plates are rotationally connected to the rotating disc, and the friction blocks are arranged on the rotating disc. The friction block is connected to the fixing shell in a sliding mode. When the child bicycle body is accelerated, through cooperation of the rotating disc, the rotating hook plate, the clamping ring and the friction block, the friction block can rub the clamping ring, so that the clamping ring, the rotating hook plate, the rotating disc and a rear wheel of the child bicycle body are decelerated, the speed of the child bicycle body can be automatically limited, the safety is high, and the child bicycle body is more convenient to use. And the speed of the child bicycle body can be prevented from being too high.

    本发明涉及儿童自行车,尤其涉及一种可调式主动限速儿童自行车。包括有儿童自行车本体、转盘、固定壳、卡环、旋转勾板、摩擦块等,所述转盘连接于所述儿童自行车本体的后轮转轴上,所述固定壳连接于所述儿童自行车本体上,所述卡环转动连接于所述固定壳内,两个所述旋转勾板均转动连接于所述转盘上,所述摩擦块滑动连接于所述固定壳上。本发明在儿童自行车本体进行加速时,通过转盘、旋转勾板、卡环和摩擦块的配合,能使摩擦块对卡环进行摩擦,从而对卡环、旋转勾板、转盘以及儿童自行车本体的后轮进行减速,如此,即可实现自动对儿童自行车本体进行限速,不仅安全性较高,而且能够防止儿童自行车本体的速度过快。
