[0082] Specifically, the limit component can include a limit block and a limit plate. The limit plate is fixedly connected to the storage rack 45 and forms an arc-shaped limit long hole. The limit block is fixedly connected to the limit component and is slidably limited in the arc-shaped limit long hole. The limit block can slide along the arc-shaped limit long hole following the opening and closing of the hood 46, so as to limit the rotation angle of the hood 46 through the limiting effect of the arc-shaped limit long hole on the limit block.

[0083] Of course, in some other embodiments, the limit component can be in other structural forms. For example, the limit component can be a foldable or expandable link structure, with one end connected to the storage rack 45 and the other end connected to the hood 46, which can fold or expand following the opening and closing of the hood 46 to limit the rotation angle of the hood 46. The limit component can also be a telescopic rod structure, with one end connected to the storage rack 45 and the other end connected to the hood 46, which can telescope following the opening and closing of the hood 46 to limit the rotation angle of the hood 46.

[0084] In one embodiment, referring to the attached Figure 1As shown, the driver's cab 4 further includes an intermediate connecting plate 47, which is fixedly connected between the front end of the seat plate 41 and the rear end of the footrest 42. With such a setting, the intermediate connecting plate 47 serves as a transition connecting plate between the seat plate 41 and the footrest 42, enabling the seat plate 41, the footrest 42, and the intermediate connecting plate 47 to form an integral plate structure, which plays a covering role for the components located below (such as the engine 5 and the crawler assembly).

[0085] Specifically, the seat plate 41, the footrest 42, and the intermediate connecting plate 47 can be an integrally formed structure or fixedly connected to each other by welding.
