The invention discloses a wheel shock-proof structure which comprises a wheel shaft and a wheel seat pivoted with a frame, the lower end of the wheel seat is rotatably connected with a wheel through the wheel shaft, the wheel shock-proof structure further comprises a shock-proof piece of an elastic structure, the upper end of the shock-proof piece is detachably connected with the upper end of the wheel seat, and the shock-proof piece can synchronously rotate along with the wheel seat. The lower end of the shock-proof piece is rotationally connected with the wheel shaft, the wheel shaft is connected to the lower end of the wheel seat in a sliding mode, the sliding of the wheel shaft drives the shock-proof piece to generate recoverable elastic deformation, and shock absorption buffering is provided through the deformation of the shock-proof piece. According to the invention, the bending deformation of the shock-proof piece which has a longer effective shock-absorbing stroke and is of an elastic structure is adopted to ensure that the wheel shock-proof structure has a better shock-absorbing effect. In addition, the invention further discloses a child carrier with the wheel shock-proof structure.
本发明公开了一种车轮避震结构,包括轮轴及用于与车架枢接的轮座,轮座的下端通过轮轴用于与车轮呈转动连接,还包括呈弹性结构的避震件,避震件的上端与轮座的上端呈可拆卸的连接,且避震件可随轮座同步的转动,避震件的下端与轮轴呈转动连接,轮轴呈滑动的连接于轮座的下端,轮轴的滑动带动避震件产生可回复的呈弹性的形变,借由避震件的形变提供减震缓冲。本发明采用具有较长有效避震行程且呈弹性结构的避震件的弯曲形变来确保车轮避震结构具有较佳的避震效果。另,本发明还公开了具有该车轮避震结构的儿童载具。
