The invention discloses a high-stability brake mechanism of a stroller. The high-stability brake mechanism comprises a fixing part, wheels and a pedal part. The fixing piece is provided with a force bearing stop block, and the fixing piece is rotatably connected with a hub of a wheel; at least part of the brake matching part is located on the side, facing the fixing piece, of the hub. The pedal piece is connected to the fixing piece and can rotate between an upper stopping position and a lower stopping position, a brake driving part is arranged on the side, facing the wheels, of the pedal piece, and a limiting groove with a downward opening is formed in the pedal piece; when the pedal piece rotates to the lower stop position, the force bearing stop block abuts against the top wall of the limiting groove, and the brake driving part is inserted into the brake matching part to limit rotation of the wheels. And when the pedal piece rotates to the upper stop position, the brake driving part retreats from the brake matching part to release the limitation on the wheels. The high-stability brake mechanism of the stroller is high in stability and reliability, simple in structure and low in manufacturing cost.
本发明公开了一种儿童推车高稳定性刹车机构,包括:固定件、车轮和脚踏件。固定件设有承力止挡块,固定件可转动地连接车轮的轮毂;刹车配合部的至少部分位于轮毂朝向固定件的一侧;脚踏件连接于固定件,且脚踏件可在上止位和下止位之间转动,脚踏件朝向车轮的一侧设有刹车主动部,脚踏件开设有开口向下的限位凹槽;脚踏件转动至下止位时,承力止挡块止抵于限位凹槽的顶壁,刹车主动部插入刹车配合部内以限制车轮转动;脚踏件转动至上止位时,刹车主动部退出刹车配合部释放对车轮的限制。所述儿童推车高稳定性刹车机构的稳定性、可靠性高,结构简单,制造成本低廉。
