Split mounting type road crash pad
The invention relates to a split mounting type road crash pad which comprises a collision mechanism and a fixing mechanism which are arranged in the direction of a lane, the two sides of the collision mechanism are each provided with a corrugated plate, the corrugated plates are slidably connected with the fixing mechanism, and a plurality of energy absorption parts are arranged between the two corrugated plates in a rectangular array mode. Each energy absorption component comprises a plurality of energy absorption units which are arranged in parallel, and each energy absorption unit is formed by splicing eight movable plates which are hinged with one another, so that the width of the energy absorption component, namely the total width, can be reduced when the energy absorption component is impacted in practice, and a buffering effect is achieved on the premise that the structure is not damaged; insertion grooves are formed in the two movable plates arranged in each energy absorption unit in parallel, a linkage rod is jointly inserted into the multiple insertion grooves, the two ends of the linkage rod in the axial direction are each provided with a compression spring I, and the positions of the compression springs I are limited, so that the whole device can be actively reset when impact force is removed, and the energy absorption effect is improved. And the deformation resistance of a single energy absorption unit can also be determined.
本发明涉及一种拼装式道路防撞垫，包括沿车道方向设置的碰撞机构、固定机构，碰撞机构两侧分别设置有一个波纹板，波纹板与固定机构滑动连接，两个波纹板之间矩形阵列排布有多个吸能部件，每个所述吸能部件包括多个并列设置的吸能单元，单个吸能单元由八个相互铰接的活动板拼接组成，从而在实际中吸能部件宽度，即总体宽度可在受冲击时减小，从而在不破坏结构的前提下起到缓冲效果，每个所述吸能单元内平行设置的两个活动板上开设有插槽，多个插槽内共同插接有一个联动杆，联动杆轴向两端分别设置有一个压缩弹簧Ⅰ，通过对压缩弹簧Ⅰ位置进行限定，即能够在冲击力撤销时使得装置整体主动复位，还能够确定单个吸能单元的抗变形力。
