The invention belongs to the technical field of power transmission and particularly relates to a hybrid power multi-gear speed changing box. The multi-degree-of-freedom power gear-shifting parallel form hybrid power multi-gear speed changing box is characterized in that power of an engine is input to an engine input shaft through a rear input shaft of a clutch; a motor module comprises a motor and a speed reducing planet row; the rotary speed of the motor is accelerated by the speed reducing planet row. A main box module of the speed changing box is composed of a multi-degree-of-freedom fixed shaft gear mechanism, and can be used for coupling power of an engine and the motor and realizing five gears matched with the engine and three gears matched with the motor. A secondary box module of the speed changing box can be used for realizing high-gear and low-gear gears, and commonly work with a main box input module of the speed changing box to realize nine gears matched with the engine and five gears matched with the motor. According to the hybrid power multi-gear speed changing box, power gear shifting is realized and the power performance of vehicles is improved; the gear-shifting quality is improved, the abrasion of the clutch is reduced and the fuel oil economical efficiency is improved.
