Description

Novel motor end cover Technical Field The utility model relates to the technical field of automobile electric drive systems, in particular to a novel motor end cover. Background Cost control of electric vehicles is increasingly prominent under the strong competition between vehicle enterprises, however, the difference in external characteristics between electric vehicles and fuel vehicles requires better NVH performance of the powertrain. Along with the new energy automobile, the integrated design cost advantage is outstanding, and the complexity of the design of parts on the power assembly is increased. At present, an electric vehicle power system requires integration and light weight, and a motor end cover in the existing electric vehicle power system has larger mass, the strength and the installation requirement of the motor end cover cannot be ensured if the light weight is required to be realized, and the product is difficult to die out, so that the motor performance is influenced. Accordingly, there is a need for a motor end cap that is lightweight and that can ensure strength and installation requirements. Disclosure of Invention The utility model aims to provide a novel motor end cover aiming at the corresponding defects of the prior art. The motor end cover can reduce the weight of the product while ensuring the strength and the installation requirement. The novel motor end cover comprises a rotary-changing stator mounting hole arranged in the center of the top surface of the outer side of the end cover and a bearing mounting hole arranged in the center of the inner side of the end cover, wherein the rotary-changing stator mounting hole and the center of the bearing mounting hole are positioned on the same axis, a junction box cover mounting seat is arranged on the outer side of the circumference of the rotary-changing stator mounting hole, a three-phase connecting port is arranged on the upper side wall of the junction box cover mounting seat, a suspension mounting seat is arranged on the outer side of the lower portion of the junction box cover mounting seat, the junction box cover mounting seat is connected with the bottom of the suspension mounting seat through an end cover wall, connecting ribs are arranged between the end cover wall and the lower junction box cover mounting seat wall and between the connecting ribs and the rotary-changing stator mounting hole wall, and a weight reducing groove with an h-shaped section is formed between the connecting ribs and the end cover wall, the lower junction box cover mounting seat wall and the rotary-changing stator mounting hole wall. The upper portion of terminal box cover mount pad is trapezoidal mount pad, and the lower part of terminal box cover mount pad is semi-circular mount pad, and trapezoidal mount pad and semi-circular mount pad constitute the terminal box cover mount pad jointly. The first threaded hole at the lower part of the junction box cover mounting seat is arranged at the upper end of the weight-reducing groove. The suspension mount is higher than the junction box cover mount. A circle of radiating ribs are arranged between the end cover wall and the bearing mounting hole. The motor end cover has the advantages that the motor end cover can meet the integrated installation requirement and the strength of the end cover while being designed in a lightweight manner, is simple to produce and process, and reduces the production cost.
