The frame body 1 is respectively connected and fixed with the two longitudinal beams 21 along two sides of the frame 200 in the transverse direction so as to cross the two longitudinal beams 21, thereby realizing the fixation with the frame 200.

Referring to fig. 3, the frame body 1 is a rectangular hollow structure, and includes two longitudinal bars 11 extending in a longitudinal direction and two cross bars 13 perpendicularly connected to two ends of the two longitudinal bars 11. The length of the longitudinal bars 11 is greater than the length of the transverse bars 13. The distance between the two side rails 11 is substantially the same as the distance between the two side members 21. When the frame body 1 is horizontally placed on the vehicle frame 200, the two longitudinal bars 11 respectively fall just above the longitudinal beams 21, horizontally engage with the upper surfaces of the longitudinal beams 21, and are thus supported by the longitudinal beams 21. Based on the front-rear direction of the frame 200, the front side of the front cross bar 13 is substantially flush with the front end surface of the longitudinal bar 11, and the rear cross bar 13 is spaced from the rear end of the longitudinal bar 11.
