DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The directional terms mentioned in the following embodiments, such as "upper", "lower", "left", "right", etc., are only references to the directions in the attached drawings. Therefore, the directional terms used are for illustration rather than to limit the present invention.

[0026] As Figure 1-6 shown, a cab frame of a skid steer loader includes a basic frame body 1 with hollow openings penetrating through each side, which reduces the overall weight and ensures the field of vision. A ceiling 2 is fixedly connected to the top of the basic frame body 1, providing necessary shelter and protection for the driver. A front panel 3 is connected to the front side of the basic frame body 1, a rear panel 4 is fixedly connected to the rear side, and side panels 5 are fixedly connected to the left and right sides. These panels together form a closed space for the cab, ensuring safety and comfort during driving. To enhance the structural strength, a first reinforcing beam 6 is fixedly connected to the upper rear part of the basic frame body 1, and a first reinforcing rib plate 7 is connected between the first reinforcing beam 6 and the basic frame body 1, which can significantly improve the load-bearing capacity and anti-deformation ability of the rear part of the cab.

[0027] Furthermore, a second reinforcing beam 8 is also fixedly connected to the upper front part of the basic frame body 1, further enhancing the structural stability of the front part of the cab.

[0028] Furthermore, a hinge plate 9 is fixedly connected to the middle part of the rear side of the basic frame body 1 for connecting other components of the loader. At the same time, a second reinforcing rib plate 10 is fixedly connected between the hinge plate 9 and the basic frame. This detailed design improves the strength and stability of the hinge area and extends the service life of the cab.

[0029] Specifically, the first reinforcing rib plate 7 and the second reinforcing rib plate 10 are triangular structures with strong stability.

[0030] To improve the load-bearing capacity of the ceiling 2, a mesh reinforcing rib 11 and a stamping reinforcing rib 12 are provided on the ceiling 2. The mesh reinforcing rib 11 is mainly distributed in the front part of the ceiling 2, providing uniform support force; while the stamping reinforcing rib 12, especially the king-shaped stamping reinforcing rib 12, is arranged in the rear part of the ceiling 2, focusing on strengthening the strength and rigidity of this area and effectively resisting the top pressure.

[0031] In addition, a bottom panel 13 is fixedly connected to the lower side of the rear panel 4, and bottom side panels 131 are fixedly connected to the left and right sides of the bottom panel 13. These components are fixedly connected to the bottom plate 14 to achieve a stable connection with the basic frame body 1, forming a complete cab bottom structure and further improving the overall structural stability and safety.

[0032] Specifically, the bottom plate 14 is arranged on the left and right sides at the bottom of the base frame 1, and a fixing portion 141 is arranged to extend in the direction between the two bottom plates 14, so that the bottom side plate 131 partially overlaps with the fixing portion 141 and is in surface contact, and they are connected by welding, which enhances the connection strength between the bottom plate 14 and the bottom side plate 131 and is relatively convenient for welding.
