Base assembly, and periphery monitoring device for vehicle
A base assembly and a periphery monitoring device for a vehicle include a base, a gasket, and a cover. The base includes a fixed part and a mounting part. The gasket is mounted to the fixed part between the fixed part and a door. The cover is mounted to and covers lower portions of the fixed part and the mounting part. A rib that has a lower rib is provided on the edge of the fixed part. The fixed part is provided with upper and lower drainage ports arranged vertically to each other. The gasket is provided with a final drainage port. As a result, the door is sealed.
1. A base assembly comprising:
a base;
a gasket; and
a cover, wherein
the base has a fixed part fixed to a vehicle body and a mounting part, a monitoring assembly being mounted to an upper portion of the mounting part,
the gasket is mounted to the fixed part and disposed between the fixed part and the vehicle body,
the cover is mounted to a lower portion of the fixed part and a lower portion of the mounting part and covers the lower portion of the fixed part and the lower portion of the mounting part,
a rib is provided on the fixed part, the rib sealing a gap between the gasket and the vehicle body by abutting the gasket to cause the gasket to come into contact with the vehicle body,
lower edge portions facing each other are provided on the lower portion of the fixed part, a lower portion of the gasket, and a lower portion of the cover,
the rib has at least a lower rib corresponding to the lower edge portion of the fixed part,
a portion of the fixed part above the lower rib is provided with,
an upper drainage port allowing water in a first space enclosed by the base, the gasket, and the cover to flow down into a second space (S 2 ) enclosed by the fixed part and the gasket, and
a lower drainage port allowing water in the second space to flow down into a third space enclosed by the base, the gasket, and the cover and positioned below the first space, the upper drainage port and the lower drainage port being arranged vertically to each other, and
a final drainage port is provided in a portion of the gasket below the lower rib and allows water in the third space to flow down to outside of the vehicle body.
2. The base assembly according to claim 1 , wherein a portion of the gasket enclosing the second space tilts from the upper drainage port to the lower drainage port.
3. The base assembly according to claim 1 , wherein a width between the base and the cover enclosing the third space is greater than a width between the base and the gasket facing each other via the lower rib.
4. The base assembly according to claim 1 , wherein
a lip portion abutting the vehicle body is provided on a tip of the lower edge portion of the gasket, and
the lip portion is provided with the final drainage port.
5. The base assembly according claim 1 , wherein a portion of the gasket in contact with the vehicle body by the rib is provided with a buffer member.
6. A periphery monitoring device for a vehicle, comprising:
the base assembly according to claim 1 , the base assembly being fixed to the vehicle body; and
a monitoring assembly mounted on the base assembly.
