Figure 2 Figure 3 ​​​​As shown, the first crossbeam 134 and the third crossbeam 133 of the top cover 13 are spaced apart, one in front of the other. Both ends of the first crossbeam 134 and the third crossbeam 133 are connected by the second longitudinal beam 131, thereby forming an integral frame. The support beam 132 is connected between the first crossbeam 134 and the third crossbeam 133 in the longitudinal direction Y. The support beam 132 is positioned adjacent to the second longitudinal beam 131, with a gap between the two support beams 132 providing ventilation.

[0052] The support beam 132 includes two spaced-apart third longitudinal beams 1321 and a plurality of fourth transverse beams 1322 connected between the two third longitudinal beams 1321. The ends of the third longitudinal beams 1321 are connected to the first transverse beam 134 and the third transverse beam 133, respectively. The third longitudinal beams 1321 are provided with a plurality of waist-shaped holes for mounting equipment, and the fourth transverse beams 1322 are provided with a plurality of energy-absorbing holes 1211.

[0053] like Figure 2 As shown, the first upright column 111 of the side wall 11 and the fourth upright column 124 of the front wall 12 are connected by multiple first ribs 121. Multiple first ribs 121 are arranged in the height direction Z. Two energy-absorbing holes 1211 are provided on each first rib 121. The first ribs 121 ensure a tight connection between the front wall 12 and the side wall 11, improving their collision resistance.

[0054] The first crossbeam 134, the second longitudinal beam 131, and the third crossbeam 133 are simultaneously connected to the top beam 114 on the same side. The first crossbeam 134 and the two second crossbeams 123 are connected via the first longitudinal beam 122. The first longitudinal beam 122 is a plate-like structure, comprising a first horizontal plate 1221, an inclined plate 1222, and a first vertical plate 1223 connected in sequence.

[0055] The first longitudinal beam 122 and the fourth column 124 are aligned vertically to form an inverted L-shape, while the second transverse beam 123 and the first rib 121 are aligned horizontally to form an inverted C-shape. In the event of a collision, the energy-absorbing holes 1211 can induce deformation and absorb energy. The support beam 132 provides partial energy absorption, preventing the top of the front wall 12 from collapsing backward, preventing significant deformation from affecting the safety of equipment in the equipment room, and preventing intrusion into the driver's cab, thereby forming a primary energy-absorbing structure.
