Title:
EMBEDDED RAISED PAVEMENT MARKER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/082267
Kind Code:
A1
Abstract:
An embedded raised pavement marker and manufacturing method therefor. The embedded raised pavement marker comprises a control module and a light emitting module, the control module and the light emitting module being circuitally connected. The embedded raised pavement marker further comprises a bottom housing and a transparent cover plate. The bottom housing is a cup-shaped structure comprising a side plate and a bottom plate. The transparent cover plate is mounted on the upper end of the bottom housing. The transparent cover plate and the bottom housing enclose to form an inner cavity. A baffle vertically extending downward is provided on the lower surface of the transparent cover plate. The baffle is an annular structure, and is attached and snap-fitted to the inner side surface of the side plate of the bottom housing. The control module and the light emitting module are provided in the inner cavity. The inner cavity is filled with a potting glue. Because the baffle of the transparent cover plate is attached and snap-fitted to the side plate of the bottom housing, and the inner cavity is internally filled with a potting glue, functional modules inside the embedded raised pavement marker are solid structures without gaps and air bubbles, such that the water-proof performance and the compression-resistant performance of the embedded raised pavement marker are improved.
