The flexible damping structure comprises a first wheel carrier and a second wheel carrier, the first wheel carrier is fixed to a first base, the second wheel carrier is fixed to a second base, and unit blocks are arranged between the first base and the second base in a linear mode; each unit block is provided with a first bulge facing the first base and a second bulge facing the second base, and the first base is also provided with a second bulge facing the adjacent unit block; the second base is also provided with a first protrusion facing the adjacent unit block. A first rotating shaft is connected between the adjacent first bulge and second bulge, and the central axis of the first rotating shaft is the same as the advancing direction of the cart; an elastic device is further arranged and used for increasing rotation resistance when the first protrusion and the second protrusion rotate around the first rotating shaft. And one of the unit blocks is connected with a frame. Damping does not depend on a frame, it is guaranteed that the frame is not deformed in the running process, the height space of the cart is not occupied greatly, and the cart can bear the span range from small vibration to large vibration.
本发明公开了一种推车柔性减震结构,包括第一轮架和第二轮架,第一轮架固定在第一基座上,第二轮架固定在第二基座上,第一基座和第二基座之间呈一字排列设置有单元块;每个单元块设有朝向第一基座的第一凸起,以及朝向第二基座的第二凸起,第一基座也设有朝向相邻单元块的第二凸起;第二基座也设有朝向相邻单元块的第一凸起;相邻的第一凸起和第二凸起之间连接有第一转轴,第一转轴的中心轴线和推车的前进方向相同;还设有弹性装置,用于在第一凸起和第二凸起绕第一转轴旋转时增大旋转阻力;择一单元块上连接有车架。本发明不依赖车架减震,保证在行驶过程中不会使车架变形,不大量占用推车的高度空间,能承受从小震动到大震动跨度范围。
