Description

Technical Field

[0001] This utility model relates to an antenna bracket structure for unmanned driving, belonging to the technical field of mining dump trucks. Background Technology

[0002] Mining areas are characterized by harsh environments, rugged roads, and constant dust, resulting in poor working conditions for drivers and frequent staff shortages. With the nation's vigorous promotion of intelligent and green mine construction, the application of unmanned driving technology in open-pit mines is becoming increasingly urgent. This technology can improve the efficiency and safety of transportation in mining areas, reduce accident rates, and enhance the economic and social benefits of mining enterprises. Among the many key components of unmanned driving technology, the placement of antennas plays a crucial role, acting as a "bridge" for information transmission.

[0066] It should be noted that multiple reinforcing ribs 29 are welded at the connection between the mounting plate 28 and the side main beam 25.

[0067] Further plans will continue to be considered. Figure 4 , Figure 6As shown, at least one wire harness fixing seat is fixed on both the bottom surface of the top rod of the side main beam 25 and the side surface of the vertical rod of the side main beam 25. That is, the wire harness of the integrated antenna 6 first extends along the wire harness fixing seats on the bottom surface of the top rod of the side main beam 25 and the side surface of the vertical rod of the side main beam 25, then extends along the wire harness fixing seat on the bottom surface of the crossbeam 22, and then extends along the wire harness fixing seat on the inner side of the support leg.

[0068] The following is a further explanation of the specific structure of the aforementioned base.

[0069] like Figure 5 , Figure 8 As shown, the base 3 is a rectangular tube assembly, which is welded together with a rectangular tube 33 and end plates 30. A support tube 31 is embedded at each of the two lateral ends of the rectangular tube 33.
