For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0045] Reference Figures 1 to 9, A white body with electromagnetic shielding function, comprising: a roof assembly, the roof 1 has mounting holes for electrical lamps and wire harness through-wall holes at the end of the electrical lamps; a front panel assembly, the front panel 2 has through-wall holes for mounting electrical wire harness through-wall plugs and air pipe through-wall holes, and at the lower left position of the front panel 2 there is a bracket for mounting the brake pedal 6 and a steering column through-wall hole, and there is a windshield glass hole above the front panel; a rear panel 3 has a waveguide ventilation window hole 13 for mounting a waveguide ventilation window; a side panel assembly, the left and right side panels 4 have door holes 25 for mounting doors; a floor assembly, the floor 5 has a floor inspection hole 21 for maintaining pipelines;

[0046] As Figure 1 shown, the outer skin steel plates of the roof 1, front panel 2, side panel 4, rear panel 3, and floor 5 are fully welded;

[0047] The wire harness through-wall holes at the end of the electrical lamps, the electrical wire harness through-wall plug through-wall holes, the air pipe through-wall holes, the steering column through-wall holes, the windshield glass hole 23, the door holes 25, the waveguide ventilation window hole 13, and the floor inspection hole 21; after the electromagnetic shielding treatment of each hole position during the later assembly, it can meet the requirements of the electromagnetic shielding index;

[0048] As Figure 2 shown, the wire harness at the end of the electrical lamp passes through the wall through a two-stage labyrinth through-wall structure, and the two through-wall structures are arranged on different spatial planes. This through-wall structure is a closed structure of a triangular cavity. Optionally, this structure can be a tetrahedral closed structure. There is a first through-wall hole 19 on the electrical lamp mounting surface, and a second through-wall hole 20 on the surface perpendicular to the electrical lamp mounting surface. In order to meet the later electromagnetic shielding, the diameter of the first through-wall hole 19 of the wire harness 18 at the end of the electrical lamp is smaller than the existing wire harness through-wall hole at the end of the electrical lamp; conductive paint is applied around the first through-wall hole 19, and the first through-wall hole 19 and the second through-wall hole 20 are on different planes, which can effectively increase the reflection attenuation of electromagnetic waves;

[0049] As Figure 3 shown, several electrical wire harness through-wall plug through-wall holes are arranged on the same through-wall plate two 17. As Figure 5 shown, several air pipe through-wall holes are arranged on the same through-wall plate one 12. Different from the existing messy electrical wire harnesses and air pipes, the through-wall plate one 12 and the through-wall plate two 17 are respectively fully welded to the front panel 2 body. The through-wall plate one 12 can effectively attenuate the electromagnetic waves entering through the wall of the front panel electrical components;

[0050] A steel plate 15 treated with electromagnetic shielding is arranged outside the through-wall plate one 12, and a metal through-wall joint 11 is arranged on the through-wall plate two 17. The air pipes 8 inside and outside the cab are connected through the metal through-wall joint 11. Since the metal through-wall joint 11 is a metal component, it is easy to ensure electrical continuity during the later electromagnetic shielding construction of the air pipe through the wall;

[0051] As Figure 4 shown, a flange 10 is provided around the through-wall hole of the steering column, and conductive paint is applied to the flange plane;. The through-wall structure of the steering column is a flange-type through-wall, and only the flange surface needs to be constructed during the later electromagnetic shielding construction, with simple process and easier to ensure the electromagnetic shielding performance;

[0052] As Figure 7 shown, a number of threaded holes three 24 for fixing the electromagnetic shielding flexible material are distributed around the windshield glass hole 23. As Figure 8 shown, a number of threaded holes four 26 for fixing the electromagnetic shielding flexible material are distributed around the door hole 25, effectively ensuring the reliability of the installation of the windshield glass and related inner liner components, the door and related inner liner components, and the electrical continuity;

[0053] As Figure 9 shown, a number of threaded holes one 14 are distributed around the waveguide ventilation window hole 13 with misalignment. Conductive treatment is carried out around the threaded holes one 14, which can effectively attenuate the electromagnetic waves entering from the rear enclosure waveguide ventilation window hole 13;

[0054] As Figure 6 shown, the floor inspection hole plate is fully welded to the floor 5 body with a steel plate with high flatness requirements. The floor inspection hole 21 is arranged at the floor inspection hole plate. A number of threaded holes two 22 are distributed around the floor inspection hole 21 with misalignment. Conductive treatment is carried out around the threaded holes two 22, which can effectively attenuate the electromagnetic waves entering from the floor inspection hole 21;

[0055] There are no through holes for the brake pedal 6 and the accelerator pedal 7 on the floor 5. All types of pedal components are arranged in the cab without direct external interfaces, avoiding electromagnetic waves directly entering the cab from the external interfaces;

[0056] The mounting holes, threaded holes one 14, threaded holes two 22, threaded holes three 24 and threaded holes four 26 are all blind holes, which can fully ensure the electrical continuity of the assembled components in the later stage of installation of each hole.
