The invention discloses a hybrid vehicle driving motor stator core structure. The hybrid vehicle driving motor stator core structure comprises a stator yoke portion with an annular structure and a ring of stator tooth portions connected with the inner ring of the stator yoke portion, wherein gullets for filling coils therein are formed between adjacent stator tooth portions, and the inner ring of the stator yoke portion and the inner end of the ring of the stator tooth portions are of buckling connection structures. According to the invention, the stator yoke portion is of an integrally formed annular structure, such that the circularity of the outer circle of a stator is guaranteed, and interference assembling between a stator iron core and a motor housing is facilitated; the stator yoke portion and the ring of the tooth portions are of the bucking connection structures, the assembling is simple, the assembling efficiency of the stator iron core is improved, and the production cost can be effectively reduced; and when the stator yoke portion and the stator tooth portions are of split structures, the stator tooth portions can be individually replaced when being damaged, replacement of the stator yoke portion is unnecessary, materials are reduced, and at the same time, the service life of a motor is prolonged.
