ANTI-COLLISION AND ANTI-BORDER-CROSSING CYLINDRICAL UNIVERSAL SPHERICAL WALL
Document Type and Number:
WIPO Patent Application WO/2022/062876
Kind Code:
A1
Abstract:
Disclosed is an anti-collision and anti-border-crossing cylindrical universal spherical wall, comprising a protective fence assembly and a cylindrical universal sphere mechanism installed on the protective fence assembly. The cylindrical universal sphere mechanism comprises a plurality of cylindrical universal sphere outer shells. The plurality of cylindrical universal sphere outer shells are connected coaxially one to another in succession by means of an intermediate support seat, and each cylindrical universal sphere outer shell may independently rotate about the central axis thereof. Two ends of the cylindrical universal sphere mechanism are separately connected to the protective fence assembly by means of a spring preloading mechanism. Several small spheres are distributed and embedded on the circumferential surfaces of the cylindrical universal sphere outer shells. The outer surface of the cylindrical universal sphere mechanism on a vertical plane is closer to the left or right side of the traveling direction of a vehicle than to the outer surface of the protective fence assembly. The overall structure of the present invention is compact, which may not only prevent high impact force, but also prevent vehicles from overturning the protective fence.
