Integrated structure of electronic power control power system for electric vehicle

Abstract

The invention discloses an integrated structure of an electronic power control power system for an electric vehicle. The integrated structure of the electronic power control power system comprises a driving motor, a speed reducer and an electronic power controller. The speed reducer is fixed to the output end of the driving motor, and the electronic power controller is fixed above the driving motor. The integrated structure of the electronic power control power system effectively reduces the size of a device, improves the integration degree of the device, integrates the connection of the driving motor and the speed reducer integrally, and simplifies the connection mode of the driving motor and the electronic power controller. In the space layout of the whole vehicle, the space utilizationrate of the electronic power control power system is improved, meanwhile, the processing cost of the product structure is reduced, and a complete and simple integrated structure of the electronic power control power system for the electric vehicle is provided for the whole vehicle; and specific lightweight design reduces the volume weight and processing cost of an electronic power control power device, and the integrated structure of the electronic power control power system can be more convenient and efficient in vehicle assembly.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to an integrated structure of an electronic power control power system for an electric vehicle. Background technique [0002] Existing electric vehicle motors, reducers, and electronic power controllers are generally arranged separately. It takes up a lot of space in the car, the structure is complex, the layout is difficult, a large number of cables are exposed, the structure cost is high, the volume is large, the installation is complicated and difficult to overhaul, and the structure placed inside the car body is not compact enough. [0003] The existing motor and reducer are composed of two independent structures. Not only the number of parts is large, but also the occupied space and weight will increase correspondingly, which is not conducive to the weight reduction of the whole vehicle and the improvement of the level of vehicle integration. [0004] Existing elec...

Problems solved by technology

It takes up a lot of space in the car, the structure is complex, the layout is difficult, a large number of cables are exposed, the structure cost is high, the volume is large, the installation is complicated and difficult to repair, and the structure placed inside the car body is not compact enough

[0003] The existing motor and reducer are composed of two independent structures, not only the number of parts is large, but also the occupied space and weight will increase correspondingly, which is not conducive to the weight reduction of the whole vehicle and the improvement of the level of vehicle integration

[0004] Existing electronic power controllers are generally independent of the motor, and the number of cables used to connect the two is large and long, resulting in a lot of space waste and difficult maintenance
