AI Technical Summary
Technical Problem
The gap between the cover and the trim of a traditional vehicle radar device can easily allow foreign objects to intrude, affecting the performance of the radar device.
Method used
A vehicle body structure was designed in which gaps are provided between the decorative parts and the cover, while the intrusion of foreign objects is suppressed by limiting walls and sealing materials. The limiting walls form a stagnant chamber and a labyrinth structure to block airflow and prevent foreign objects from reaching the radar device.
Benefits of technology
It effectively inhibits the intrusion of foreign objects, improves the performance of radar devices and traffic safety, and prevents performance degradation caused by foreign object adhesion.

Abstract
The present application relates to a vehicle body structure including a garnish provided on an outer side of a vehicle, an adapter joined to the garnish, a radar device supported by the adapter, and a cover joined to the garnish and covering the radar device. The garnish includes a mounting hole, a first annular rib extending to surround the mounting hole, and an annular surface defined by an edge portion of the mounting hole and the first annular rib. The adapter is joined to a back side of the garnish at a position corresponding to the mounting hole. The cover includes a plate-like portion arranged inside the first annular rib, the plate-like portion having an outer edge portion opposite an inner side surface of the first annular rib with a first gap therebetween and covering the mounting hole, and a limiting wall protruding from a back side of the plate-like portion toward the annular surface.
