Abstract

The invention provides a motor rotor structure of an electric vehicle, wherein the motor rotor structure is used in the technical field of motors of electric vehicles. The motor rotor structure comprises a rotor core body (1), wherein the middle part of the rotor core body (1) is provided with a rotor shaft (2), a front pressing plate (3) of the motor rotor structure is adhered to an iron core front end surface (5) of the rotor core body (1), a rear pressing plate (4) is adhered to an iron core rear end surface (11) of the rotor core body (1), a rivet (6) passes through the front pressing plate (3), the rear pressing plate (4) and the rotor core body (1), and each rivet (6) is configured to be a structure capable of fixedly riveting and connecting the front pressing plate (3), the rear pressing plate (4) and the rotor core body (1). The motor rotor structure of the electric vehicle has the advantages of being simple in structure, low in manufacturing cost, capable of reducing axial size of the motor rotor structure by simple improvement on the basis of an original motor, reducing weight of the rotor structure, reducing rotational inertia, and decreasing processing cost.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle motors, and more specifically relates to a rotor structure of electric vehicle motors. Background technique [0002] At present, the rotor mechanism of a motor is usually composed of a rotor end plate, a rotor core, and a rotor shaft. The rotor end plate is fixed on the rotor shaft by a round nut, and at the same time, the rotor end plate is snugly connected with the rotor core. In the rotor structure in the prior art, due to the existence of the thicker rotor end plate, the axial dimension of the motor rotor structure is larger, so that the overall length of the motor increases, the weight increases, the cost increases, and the power density decreases, and it affects the entire motor. The layout in a limited space cannot meet the requirements of assembly and use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple stru...
