CITATION LIST

Patent Literature

• [Patent Literature 1] Japanese Patent Application Laid-Open No. 2018-95039

However, in the structure described in Patent Literature 1, since the radar device is mounted in a so-called cantilevered state, the radar device cannot be stably held, and there is a possibility that the accuracy of object detection by the radar device may not be sufficiently improved due to the influence of the vibration of the vehicle body transmitted to the radar device. Moreover, since access to the radar device is not easy, it may take time and effort to replace or maintain the radar device. Furthermore, since a part of the radar device is not covered, there is a concern that the radar device may be submerged by rainwater or the like.

In view of the above, the disclosure provides a mounting structure of an object detection device to a vehicle body which has a simple configuration and is capable of improving the accuracy of object detection by the object detection device and improving the maintainability and durability of the object detection device.

Further, in this mounting structure of the object detection device to the vehicle body, the connection member (40) may be a member that connects between a lower end (12b) of the first lamp device (10) and an upper end (22a) of the second lamp device (20) in an up-down direction, and the object detection device (30) may be disposed between the first lamp device (10) and the second lamp device (20) in the up-down direction.

According to the mounting structure of the object detection device to the vehicle body according to the disclosure, the object detection device is mounted on the connection member that connects the first lamp device and the second lamp device disposed in the up-down direction. In this way, the object detection device is supported by both the first lamp device and the second lamp device via the connection member. In this way, the object detection device does not need to be in a so-called cantilevered state, and the object detection device may be stably held on the vehicle body. Therefore, although the object detection device has a relatively simple structure, it is possible to easily and accurately position and support the object detection device on the vehicle body, and the object detection accuracy of the object detection device may be improved.

Further, this mounting structure of the object detection device to the vehicle body may further include a cover member (33) covering at least a part of the object detection device (30) on a side in a first direction, which is an object detection direction.

According to this configuration, by including the cover member, the object detection device may be protected from being exposed to water from the outside. Therefore, the durability of the object detection device may be improved.

Further, in this mounting structure of the object detection device to the vehicle body, a surface (33c) of the cover member (33) on the side in the first direction may be disposed to be a continuous surface with at least one of a surface (13c) of the first lamp device (10) on the side in the first direction and a surface (23c) of the second lamp device (20) on the side in the first direction.

According to this configuration, since a surface of the object detection device and at least one of a surface of the first lamp device and a surface of the second lamp device are disposed to form a continuous surface, the exterior design of the vehicle body including the first lamp device, the second lamp device and the object detection device may be improved.

Further, in this mounting structure of the object detection device to the vehicle body, the cover member (33) may be detachably mounted on the first lamp device (10) and the second lamp device (20).

According to this configuration, since the cover member is detachably mounted on the first lamp device and the second lamp device, the cover member may be easily mounted and dismounted; therefore, the maintainability of the object detection device may be improved.

Further, in this mounting structure of the object detection device to the vehicle body, the cover member (33) may be detachably mounted on the connection member (40).

According to this configuration, since the cover member is detachably mounted on the connection member, the cover member may be easily mounted and dismounted; therefore, the maintainability of the object detection device may be improved.

Further, in this mounting structure of the object detection device to the vehicle body, the first lamp device (10) may include a first light source (11) and a first housing (12) that accommodates the first light source (11), and the second lamp device (20) may include a second light source (21) and a second housing (22) that accommodates the second light source (21), and the connection member (40) may be formed integrally with at least one of the first housing (12) and the second housing (22).

According to this configuration, since the connection member is integrally formed with at least one of the first housing and the second housing, it is possible to reduce the number of components of the vehicle body including the first lamp device, the second lamp device, and the object detection device, simplify the configuration, and reduce the weight. Further, it may also contribute to simplification of the assembly process of the vehicle body and shortening of the assembly time.

Further, in this mounting structure of the object detection device to the vehicle body, the first lamp device (10) may include a first light source (11) and a first outer member (13) that covers at least a side in the first direction of the first light source (11), and the second lamp device (20) may include a second light source (21) and a second outer member (23) that covers at least a side in the first direction of the second light source (21), and the connection member (40) may be formed integrally with at least one of the first outer member (13) and the second outer member (23).

According to this configuration, since the connection member is integrally formed with at least one of the first outer member and the second outer member, it is possible to reduce the number of components of the vehicle body including the first lamp device, the second lamp device, and the object detection device, simplify the configuration, and reduce the weight. Further, it may also contribute to simplification of the assembly process of the vehicle body and shortening of the assembly time.
