Hybrid power drive system, gearbox, and vehicle

A gearbox, configured to receive power output by an engine and a drive motor, wherein the gearbox comprises:

• a gearbox body,
• a first output end,
• a first input end, and
• a second input end, wherein both the first input end and the second input end are in transmission connection with the first output end through the gearbox body;
• and in an axial direction of the first input end, the first input end and the second input end are located on a same side of the gearbox body;
• the first input end is configured to be in transmission connection with an output end of the engine disposed on the side of the gearbox body, and is configured to receive power output by the engine;
• and the first input end is further configured to be in transmission connection with a generator;
• the second input end is configured to be in transmission connection with an output end of the drive motor disposed on the side of the gearbox body, and is configured to receive power output by the drive motor;
• and
• the first output end is configured to receive the power transmitted by the first input end or the second input end, and provide the power to wheels.
