Harness routing structure for electric vehicle
An electric vehicle harness routing structure is provided for an electric vehicle having an electric motor as a drive source, a control device to control the electric motor as well as charging of a battery for power supply to the electric motor, and a power unit elastically supported on a vehicle body. The harness routing structure includes a charging port, a quick charging harness, a normal charging harness, a first quick-charge harness clip, a second quick-charge harness clip, a first normal-charge harness clip and a second normal-charge harness clip. The clips of the electric vehicle harness routing structure is provided such that when connecting a relatively movable power unit and charging ports with the quick charging harness and the normal charging harness, it is possible to prevent interference of between the charging harnesses.
1. An electric vehicle harness routing structure adapted to be coupled to a power unit elastically supported on a vehicle body, the harness routing structure comprising:
a charging port fixedly supported on the vehicle body;
a quick charging harness configured to be connected to the power unit and the charging port;
a normal charging harness configured to be connected to the power unit and the charging port, the normal charging harness being more flexible than the quick-charge harness;
a first quick-charge harness clip coupled to a first intermediate portion of the quick charging harness, the first quick-charge harness clip being configured to be fixed to the vehicle body,
a second quick-charge harness clip coupled to a second intermediate portion of the quick charging harness between the first quick-charge harness clip and the power unit, the first quick-charge harness clip being configured to be fixed to the power unit,
a first normal-charge harness clip coupled to a first intermediate portion of the normal charging harness, the first normal-charge harness clip being configured to be fixed to the vehicle body; and
a second normal-charge harness clip by coupled to a second intermediate portion of the normal charging harness between the first normal-charge harness clip and the power unit, the second normal-charge harness clip being configured to be fixed to the power unit,
the normal charging harness between a normal body-side constraint point adjacent to the first normal-charge harness clip and a normal unit-side constraint point by adjacent to the second normal-charge harness clip is shorter in length than the quick charging harness between the quick body-side constraint point adjacent to the first quick-charge harness clip and the second quick unit-side constraint point adjacent to the second quick-charge harness clip.
2. The electric vehicle harness routing structure as claimed in claim 1 , wherein the quick body-side constraint point is aligned with the normal body-side constraint point as viewed in a vehicle longitudinal direction, and the normal unit-side constraint point is located more forward than the quick-charge unit-side constraint point with respect to the vehicle longitudinal direction.
3. The electric vehicle harness routing structure as claimed in claim 1 , wherein
the normal unit-side constraint point is disposed at a higher vehicle vertical position than a vehicle vertical position of the quick unit-side constraint point.
4. The electric vehicle harness routing structure as claimed in claim 1 , wherein
the second normal-charge harness clip is arranged such that the normal unit-side constraint point is angled forward with respect to a vehicle vertical direction and thereby restraining the normal-charge harness in an obliquely inclined state.
5. The electric vehicle harness routing structure as claimed in claim 2 , wherein
the normal unit-side constraint point is disposed at a higher vehicle vertical position than a vehicle vertical position of the quick unit-side constraint point.
6. The electric vehicle harness routing structure as claimed in claim 5 , wherein
the second normal-charge harness clip is arranged such that the normal unit-side constraint point is angled forward with respect to a vehicle vertical direction and thereby restraining the normal-charge harness in an obliquely inclined state.
7. The electric vehicle harness routing structure as claimed in claim 2 , wherein
the second normal-charge harness clip is arranged such that the normal unit-side constraint point is angled forward with respect to a vehicle vertical direction and thereby restraining the normal-charge harness in an obliquely inclined state.
8. The electric vehicle harness routing structure as claimed in claim 3 , wherein
the second normal-charge harness clip is arranged such that the normal unit-side constraint point is angled forward with respect to a vehicle vertical direction and thereby restraining the normal-charge harness in an obliquely inclined state.
