[0029] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0030] This embodiment proposes a cabin cross beam structure, such as Figure 1 As shown, the conventional cabin crossbeam assembly 1 is welded by a plurality of parts including a cabin crossbeam 101, a battery cooler bracket 102, a thermal management integrated module lower mounting bracket I 103, a high-voltage harness fixing bracket 104, a thermal management integrated module lower mounting bracket II 105, and a compressor high-voltage harness fixing bracket 106. Its complex structure, lengthy production process chain, and low dimensional accuracy increase the cost and weight of the vehicle.
