The invention provides an axial motor rotor, an axial motor, a power assembly and a vehicle, the axial motor rotor comprises a rotor bracket and a magnet structure, the rotor bracket comprises a first supporting part and a second supporting part which are coaxially arranged, and the first supporting part sleeves one side, far away from the axis of the second supporting part, of the second supporting part; a plurality of magnet units in the magnet structure are sequentially arranged in the circumferential direction, each magnet unit is located between the first supporting part and the second supporting part, and the two ends, in the radial direction of the second supporting part, of each magnet unit are fixed to the first supporting part and the second supporting part correspondingly. At least part of the first soft magnets and at least part of the first permanent magnets in the magnet units are stacked in the axial direction. The multiple magnet units are arranged in a surrounding mode to form the magnet structure, the machining process of each magnet unit is simpler, the magnet units are fixed through the rotor support, and the reliability is improved; the first soft magnet is used for gathering magnetic lines, improving air gap flux density, increasing output torque and improving axial motor performance.
