The invention provides an automatic braking structure which is used for braking a bicycle trailer, a pair of trailer wheel axles of the bicycle trailer are coaxially connected through a trailer transverse shaft, and the trailer transverse shaft can drive the pair of trailer wheels to roll forwards under the traction of external force; the automatic brake structure is assembled on a trailer transverse shaft and arranged on the inner side of a trailer wheel and comprises a brake pad, a clutch plate, a clutch plate spring, a sliding block, a guide rod, a guide rod spring and a wedge block, the wedge block can slide in the radial direction of the trailer transverse shaft or backwards till the clutch plate abuts against the brake pad through an inclined face, and the brake state of the trailer wheel is formed. Or the clutch plate slides forwards to the inclined surface to be separated from the clutch plate, so that the braking state is released. The invention further provides a bicycle trailer and a bicycle provided with the automatic braking structure, braking power does not need to be additionally provided for the bicycle trailer, the structure is simple, cost is low, and the using effect is good.

    本发明提供了一种自动刹车结构,用于对自行车拖车的制动,自行车拖车的一对拖车轮轮轴之间通过拖车横轴同轴联接,拖车横轴在外力牵引下能够带动一对拖车轮向前滚动行进;自动刹车结构装配在拖车横轴上,设置在拖车轮的内侧,包括刹车片、离合片、离合片弹簧、滑动块、导向杆、导向杆弹簧、楔形块,楔形块能够顺着拖车横轴的径向,或向后滑动至以斜面将离合片抵紧至与刹车片贴合,构成对拖车轮的制动状态,或向前滑动至斜面与离合片分离,构成对制动状态的解除。本发明还提出了设有该自动刹车结构的自行车拖车与自行车,无需额外为自行车拖车提供刹车动力,结构简洁、成本低廉、使用效果好。
