Differential gearbox structure and vehicle

The invention relates to a differential gearbox structure and a vehicle, and the differential gearbox structure comprises a first shaft which is sleeved with a low-gear normally engaged gear; the second shaft is sleeved with a high-gear normally engaged gear, a reverse gear, a first-gear gear, a second-gear gear and a third-gear gear; the intermediate shaft and the first shaft are arranged in a spaced mode, and the intermediate shaft is fixedly connected with a normally-meshed intermediate gear and a gear intermediate gear; wherein the normally engaged intermediate gear is engaged with the low-gear normally engaged gear, and the normally engaged intermediate gear is engaged with the high-gear normally engaged gear; the reverse gear, the first-gear gear, the second-gear gear and the third-gear gear are all meshed with the gear intermediate gear; the first shaft can drive the low-gear constant meshing gear or the high-gear constant meshing gear to rotate. According to the differential gearbox structure and the
