Description

Technical Field

[0001] The utility model relates to the field of automobile wiring harnesses, and specifically refers to a fixing device for new energy automobile wiring harnesses. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source, integrate advanced technologies in vehicle power control and driving, and have advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. With the continuous development of the new energy vehicle industry, automotive electrical appliances and other control systems are also constantly developing towards refined functions, complex structures, and diversification. Various types of wiring harnesses and pipelines run through the vehicle body, which requires a fixing device to arrange and fix the wiring harnesses.

[0003] When using the existing fixing device for the wiring harness of new energy vehicles, not all the cross-sectional diameters of the wiring harness will exactly match the inner diameter of the fixing groove. When the cross-sectional diameter of the wiring harness is smaller than the inner diameter of the fixing groove, the fixing effect of the fixing device on the wiring harness will be reduced, making the wiring harness easy to slide inside the fixing groove, thereby causing wear on the wiring harness and affecting the service life of the wiring harness.
