IN-VEHICLE RADAR DEVICE AND COVER FOR IN-VEHICLE RADAR DEVICE
First Claim
1. An in-vehicle radar device which radiates electromagnetic waves and receives reflected waves, from an object, of the electromagnetic waves so as to detect a location of the object, the in-vehicle radar device comprising:
- a transmission-and-reception section that transmits the electromagnetic waves and receives the reflected waves;
a detection section that detects the location of the object based on the reflected waves; and
a cover member that covers the transmission-and-reception section in a manner that a rear surface of the cover member faces a transmission-and-reception surface of the transmission-and-reception section, whereinthe cover member includes at least;
a cover portion that covers the transmission-and-reception surface; and
a lower protrusion portion that is provided below the cover portion and formed so as to protrude on a surface side of the cover member with respect to the cover portion,at least the cover portion and the lower protrusion portion being formed of material through which the electromagnetic waves are transmitted.

Abstract
Provided is an in-vehicle radar device and a cover for the in-vehicle radar device which are capable of accurately detecting an object.
The in-vehicle radar device radiates electromagnetic waves and receives reflected waves, from the object, of the electromagnetic waves so as to detect a location of the object, and includes: a transmission-and-reception section that transmits the electromagnetic waves and receives the reflected waves; a detection section that detects the location of the object based on the reflected waves; and a cover member that covers the transmission-and-reception section in a manner that a rear surface of the cover member faces a transmission-and-reception surface of the transmission-and-reception section, and the cover member includes: a cover portion that covers the transmission-and-reception surface; and a lower protrusion portion that is provided below the cover portion and formed so as to protrude on a surface side of the cover member with respect to the cover portion, the cover portion being formed of a material through which the electromagnetic waves are transmitted.

9. A cover for an in-vehicle radar device, the cover covering a transmission-and-reception section, which is provided on the in-vehicle radar device, for the electromagnetic waves such that a rear surface of the cover faces a transmission-and-reception surface of the transmission-and-reception section, the in-vehicle radar device radiating the electromagnetic waves and receiving reflected waves, from an object, of the electromagnetic waves so as to detect a location of the object, the cover for an in-vehicle radar device comprising at least:
-
a cover portion that covers the transmission-and-reception surface; and a lower protrusion portion which is provided below the cover portion and formed so as to protrude on a surface side of the cover for an in-vehicle radar device with respect to the cover portion in order to prevent water drops from below and dirt-containing water drops from below from adhering to the surface of the cover portion, at least the cover portion and the lower protrusion portion being formed of materials through which the electromagnetic waves are transmitted.
