Abstract
An engine room harness routing structure is provided that allows a harness trunk line to be routed without imposing restrictions on the design of the vehicle body. The harness trunk line is housed in an upper position inside a cowl box having a relatively large amount of leeway in its cross sectional area and is routed in the widthwise direction of the vehicle inside the cowl box. Consequently, there is no need to secure space for mounting the harness between the under surface of the cowl box and the upper surface a brake master cylinder back installed there below. As a result, the problem of the height of the cowl box from the ground increasing and affecting the design of the vehicle body can be avoided and the layout of harness trunk line can be established so as not to restrict the vehicle model.
Claims20
An engine room harness routing structure for a vehicle, the engine room harness routing structure comprising:
- a cowl box configured to extend in a widthwise direction of the vehicle;
- and
- a harness trunk line partially housed within an upper inside region of the cowl box to extend in the widthwise direction of the vehicle inside the cowl box such that the harness trunk line within the upper inside region of the cowl box is spaced upwardly from a bottom of the cowl box, the harness trunk line being configured to be electrically coupled to a battery to supply battery voltage to at least one electrical component installed inside an engine room of the vehicles,
- the cowl box including at least one lateral end opening arranged to open within the engine room with the harness trunk line extending therethrough.
An engine room harness routing structure for a vehicle, the engine room harness routing structure comprising:
- cowl box means for forming an elongated housing configured to extend in a widthwise direction of the vehicle;
- and
- harness trunk line means for electrically coupling a battery to at least one electrical component installed inside an engine room of the vehicle for supplying battery voltage to the at least one electrical component installed inside the engine room of the vehicle, the harness trunk lint means being partially housed within an upper inside region of the cowl box means to extend in the widthwise direction of the vehicle inside the cowl box means such that the harness trunk line means within the upper inside region of the cowl box means is spaced upwardly from a bottom of the cowl box means,
- the cowl box means including at least one lateral end opening arranged to open within the engine room with the harness trunk line means extending therethrough.
A method of muting a harness trunk line in an engine room of a vehicle comprising:
- forming a cowl box in a rearward portion of the engine room that is configured to extend in a widthwise direction of the vehicle;
- partially installing a harness trunk line within an upper inside region of the cowl box to extend in the widthwise direction of the vehicle inside the cowl box such that the harness trunk line within the upper inside region of the cowl box is upwardly from a bottom of the cowl box;
- and
- electrically coupling the harness trunk line between a battery and at least one electrical component installed inside the engine room of the vehicle by extending the harness trunk line through at least one lateral end opening of the cowl box arranged to open within the engine room.
An engine room harness routing structure for a vehicle, the engine room harness routing structure comprising:
- a cowl box configured to extend in a widthwise direction of the vehicle;
- and
- a harness trunk line having a section partially housed within an inside region of the cowl box to extend in the widthwise direction of the vehicle inside the cowl box, the section of the harness trunk line being located completely in an upper half of the cowl box, the harness trunk line being configured to be electrically coupled to a battery to supply battery voltage to at least one electrical component installed inside an engine room of the vehicle.
