The invention discloses a series-parallel two-gear gearbox assembly and a hybrid electric vehicle. The gearbox assembly comprises an engine, a generator, a driving motor, a transmission mechanism, a clutch and a differential mechanism. An output shaft of the engine is coaxially connected with a first shaft in the transmission mechanism; the driving motor and the generator are coaxially provided with gears, and the gears are respectively in meshing transmission with the gear on the first shaft; and the transmission mechanism further comprises a fourth shaft, and two gears are arranged on the fourth shaft and meshed with the gears on the first shaft respectively. According to the engine, power output of two speed transmission ratios can be achieved, and efficient output is achieved in a medium-speed area and a high-speed area; the gear shifting process can be completed through the speed regulation characteristic of the generator, in the two-speed-ratio switching process of the engine, the driving motor is connected with the wheel end all the time, the driving force of the wheel end is not interrupted, and the gear shifting process is smoother; and the driving motor can achieve three-level driving, a large speed transmission ratio can be set, and high-rotating-speed output can be taken into consideration.
