[0031] Please refer to Figure 1-Figure 3 The utility model discloses a mounting structure for an automobile motor inspection cover, wherein an embedded plate 600 is provided below an automobile bottom plate 100;

[0032] The inspection cover 300 is provided with a first connecting plate 310 at its edge. The first connecting plate 310 is bent inwardly to form a hook portion 330. The hook portion 330 can abut against the vehicle floor 100. The hook portion 330 extends inwardly to form a second connecting plate 320. A filling gap is defined between the second connecting plate 320 and the vehicle floor 100. An isolation pad 400 is provided in the filling gap.

[0033] The first connecting plate 310 , the second connecting plate 320 , the vehicle floor panel 100 and the embedded plate 600 are connected by bolts.

[0034] Specifically, a first connecting plate 310 is provided at the edge of the inspection cover 300. The first connecting plate 310 bends inward to form a hook portion 330, which then extends inward to form a second connecting plate 320. The hook portion 330 can abut against the vehicle floor 100 to isolate the interior of the motor 200 from the exterior. Bolts are used to secure the first connecting plate 310, the second connecting plate 320, the vehicle floor 100, and the embedded plate 600. Bolts are inserted through all four plates simultaneously, effectively improving the strength and stability of the bolted connection, allowing it to withstand greater shaking during vehicle operation without loosening.
