Wiring devices for pure electric vehicles, power systems and drive motors

Abstract

The invention discloses a wiring device for a driving motor for a pure electric vehicle. The wiring device comprises a box body, a three-phase wiring platform arranged inside the box body, a box cover matched with the box body in a sealed manner, a three-phase wire harness matched with any one of a plurality of sets of three-phase wiring holes; a low-voltage plug connector socket and the plurality of sets of three-phase wiring holes are arranged on side surfaces of the box body respectively; the included angle between the extending directions of each two sets of three-phase wiring holes is larger than 0 degree; the distances between the plurality of sets of three-phase wiring holes and corresponding wire connecting platforms are different; each wire harness comprises a wire harness body connected to a connecting hole part of the three-phase wiring holes, and a wiring end part positioned between one wiring hole and one three-phase wiring platform and connecting the wire harness body with a wiring platform on the three-phase wiring platform, which corresponds to the wire harness body. The device has higher universality and has an anti-misconnection function. The invention further discloses a power system employing the wiring device and a pure electric vehicle employing the power system.

Description

technical field [0001] The present invention relates to the technical field of vehicle manufacturing, in particular to a wiring device for a driving motor of a pure electric vehicle. The present invention also relates to a power system of a pure electric vehicle having the above-mentioned wiring device for a driving motor. A pure electric vehicle with the above-mentioned power system. Background technique [0002] In recent years, with the increasingly serious energy crisis and environmental pollution problems worldwide, people's requirements for energy saving and emission reduction of automobiles have gradually increased. Pure electric vehicles are characterized by low noise, no pollution, diversified energy sources, and high energy efficiency. The characteristics have received more and more attention from people, thus promoting the accelerated development of pure electric vehicles. [0003] In the structural design of pure electric vehicles, the driving motor system is on...

Problems solved by technology

[0004] However, the drive motors and motor controllers of different types of pure electric vehicles are arranged differently in the engine compartment, so the wiring harness outlet directions of the drive motors of different models are different. Correspondingly, the wiring of each drive motor in the prior art The box only corresponds to the drive motor with the same wiring harness outlet direction, that is, the wiring direction of the junction box of each drive motor is single, and then, the problem of poor versatility of the junction box of the drive motor between different models is caused.
