Description

Technical Field

[0001] The utility model relates to the technical field of drive motors, in particular to a flexible fixing structure of a three-phase wire harness of a drive motor. Background Art

[0002] The existing products in the market include: The three-phase wiring harness fixing structure of the drive motor is an important part of the drive system, which can avoid the wiring harness wear caused by the spatial movement of the drive motor when it is working. At present, the three-phase wire fixing in the market is mainly fixed directly on the relatively static parts of the vehicle by cable ties, pressure plates, etc.

[0003] The main problem with existing products is that one end of the three-phase wiring harness of the drive motor and the other end fastened to the motor are fixed to the relatively static parts of the vehicle with cable ties or pressure plates. The length of the wiring harness at these two fixed ends is lengthened to adapt to the spatial movement of the wiring harness with the motor and avoid movement wear of the wiring harness. However, if the space between the two fixed ends is too small, this solution will fail, otherwise it will cause movement wear of the wiring harness or the detachment of the wiring harness connector at the motor end.
