Abstract

A radar device (1) is mounted on a monitoring device. The radar device (1) comprises: a radio wave source (2) that emits a radio wave (2A) for detecting information regarding the surrounding environment of the monitoring device; and a support body (4) that has a first region (A1) and a second region (A2), and supports a conductor (5). The first region (A1) is positioned on a propagation path of the radio wave (2A), and the second region (A2) supports a member provided with a function different from detection of information. The conductor (5) has a horizontal portion (51) extending in a first direction (D1) that is non-parallel to the direction of an electric field (2B) of the radio wave (2A) in the first region (A1).

Description

Radar equipment, lighting equipment, and monitoring equipment This disclosure relates to radar equipment and illumination equipment mounted on a monitoring device. This disclosure also relates to the monitoring device on which the radar equipment or illumination equipment is mounted. Patent Document 1 discloses a radar device for detecting information about the surrounding environment of a vehicle, as an example of a monitoring device. This radar device is housed in a lighting chamber together with a lighting device that emits illumination light. The radar device is covered with a light guide plate so that it cannot be seen from outside the vehicle. A radar system according to one embodiment is schematically illustrated.Figure 1 illustrates a vehicle equipped with the radar system shown.Figure 1 schematically illustrates the radar and support structure.Figure 1 schematically shows another example of the radar and support structure.A schematic illustration of a lighting device according to one embodiment is shown. The following describes an example of an embodiment in detail, referring to the attached drawings. The scale of each drawing used in the following description has been appropriately adjusted to ensure that each component is recognizable. In the attached drawing, arrow F indicates the front direction of the illustrated structure. Arrow B indicates the rear direction of the illustrated structure. Arrow U indicates the upward direction of the illustrated structure. Arrow D indicates the downward direction of the illustrated structure. Arrow L indicates the left direction of the illustrated structure. Arrow R indicates the right direction of the illustrated structure. These directional expressions are used for explanatory purposes only and do not limit the actual orientation or direction of the illustrated structure in use. Note that the terms "left" and "right" used in the explanation referring to vehicle 100 as an example in Figure 2 indicate the left and right directions as seen from the driver's seat. As used herein, the term "forward-backward direction" refers to the direction along the forward and backward directions described above. As used herein, the term "upward-downward direction" refers to the direction along the upward and downward directions described above. As used herein, the term "left-right direction" refers to the direction along the left and right directions described above. As used herein, the expression "extending vertically" includes extending at an angle relative to the vertical direction, meaning extending with an angle closer to the vertical direction than to the front-to-back and left-to-right directions. As used herein, the expression "extending in the left-right direction" includes extending at an angle to the left-right direction, meaning extending with an angle closer to the left-right direction than to the front-back and up-down directions. <Radar equipment> Figure 1 schematically illustrates a radar device 1 according to one embodiment. Figure 2 illustrates a vehicle 100 on which the radar device 1 is mounted. The vehicle 100 is an example of a mobile device and also an example of a surveillance device. The shape of the vehicle body of the vehicle 100 is for illustrative purposes only. As illustrated in Figure 1, the radar system 1 includes a radar 2. The radar 2 is, for example, a millimeter-wave radar or a microwave radar. The radar 2 is an example of a radio wave source.
