Multi-input multi-gear new energy gearbox transmission structure

The utility model relates to the technical field of mine truck gearboxes, in particular to a multi-input multi-gear new energy gearbox transmission structure which comprises a first input assembly, a second input assembly, a third input assembly, a fourth input assembly and a total output assembly. The third input assembly and the fourth input assembly converge and are connected with a second normally-engaged output unit, the first normally-engaged output unit is coaxially connected with a first front intermediate shaft and a first rear intermediate shaft which are in linkage, and the second normally-engaged output unit is coaxially connected with a second front intermediate shaft and a second rear intermediate shaft which are in linkage. A fourth-gear gear set and a third-gear gear set are connected between the first front intermediate shaft and the second front intermediate shaft, a second-gear gear set and a first-gear gear set are connected between the first rear intermediate shaft and the second rear int
