Problems to be Solved by the Invention

[0004] In the technique of Patent Document 1, as shown in FIG. 2, the high-voltage harness 36 is protected at a position behind the base member 16. However, the harness is arranged in various paths within the power unit mounting room, and protection is also required in other places, and it is necessary to protect it from an impact load from the front of the vehicle.

[0005] In view of such problems, an object of the present invention is to provide a vehicle harness holding structure capable of holding a harness in an emergency.

Means for Solving the Problems

[0006] To solve the above problems, a typical configuration of the vehicle harness holding structure according to the present invention is a vehicle harness holding structure comprising a power unit mounted in the power unit mounting room of a vehicle, a harness routed between a predetermined first electrical component located above the power unit and a predetermined second electrical component located to the side of the power unit, and a bracket attached to the power unit to hold the harness, wherein the bracket has a coupling portion coupled to the side of the power unit on the second electrical component side and a holding portion that holds the harness at a position higher than the power unit, and the trajectory when the bracket rotates back and forth with the coupling portion as the center of rotation does not overlap with the harness. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a vehicle harness holding structure that can hold the harness in an emergency. [Brief explanation of the drawing]

[0008] [Figure 1] This figure shows an overview of a vehicle harness holding structure according to an embodiment of the present invention. [Figure 2] Figure 1(b) is a perspective view showing the bracket alone from various directions. [Figure 3] This diagram shows the harness retention structure of Figure 1(a) as viewed from the front. [Figure 4] This is a magnified view of the bracket in Figure 3(b). [Figure 5] This is a view of the harness holding structure shown in Figure 3(a) from above. [Figure 6] This diagram shows the harness holding structure in Figure 3(a) as viewed from the right side in the vehicle width direction. [Figure 7] This is a magnified view of the bracket in Figure 6(b). [Figure 8] Figure 7 is a cross-sectional perspective view of the bracket. [Figure 9] This figure shows a modified version of the bracket shown in Figure 2(c). [Modes for carrying out the invention]

[0009] A vehicle harness holding structure according to one embodiment of the present invention comprises a power unit mounted in the power unit mounting room of a vehicle, a harness routed between a predetermined first electrical component located above the power unit and a predetermined second electrical component located to the side of the power unit, and a bracket attached to the power unit to hold the harness, wherein the bracket has a coupling portion coupled to the side of the power unit on the second electrical component side and a holding portion that holds the harness at a position higher than the power unit, and the trajectory of the bracket when it rotates back and forth with the coupling portion as the center of rotation does not overlap with the harness.

[0010] The bracket described above may tilt backward around its joint if it receives a load from the front, for example, in a frontal collision. In this configuration, the trajectory of the bracket when it rotates back and forth around its joint does not overlap with the harness. Therefore, contact between the edge of the bracket and the harness is prevented, thus preventing damage to the harness. Thus, with this configuration, the harness can be held securely even in emergencies.

[0011] The above-mentioned retaining portion may be positioned closer to the center of the power unit in the vehicle width direction than the connecting portion.

[0012] The aforementioned retaining portion is positioned closer to the center of the power unit than the connecting portion. The power unit exhibits high rigidity during frontal collisions, etc. Therefore, by positioning the retaining portion towards the center of the power unit, the rigidity of the power unit can be used to distribute the load that may be applied to the retaining portion. Thus, deformation of the retaining portion can be suppressed, and the harness can be held securely.

[0013] The above bracket may further include a first vertical wall portion extending upward from the connecting portion, and a cross-member portion formed between the first vertical wall portion and the holding portion and bending and extending from the first vertical wall portion toward the center in the vehicle width direction of the power unit.

[0014] By having the first vertical wall portion extending in the vertical direction and the cross-member portion extending in the horizontal direction, the above bracket can ensure rigidity against loads in the vertical and horizontal directions. Therefore, according to the above bracket, it becomes possible to suitably hold the harness.

[0015] The above bracket may further include a second vertical wall portion formed between the cross-member portion and the holding portion and bending and extending upward from the cross-member portion.

[0016] According to the above configuration, by having the second vertical wall portion extending in the vertical direction, the bracket can further ensure rigidity against loads in the vertical direction and can suitably hold the harness.

[0017] The above holding portion holds the harness in the front-rear direction and may be inclined such that the rear side is located closer to the center in the vehicle width direction of the power unit than the front side.

[0018] According to the above configuration, since the holding portion is inclined toward the center in the vehicle width direction of the power unit, the harness can be arranged closer to the center in the vehicle width direction of the power unit. Therefore, according to the above configuration, it becomes possible to improve the degree of freedom in arranging the harness according to the inclination of the holding portion.

[0019] The above connecting portion may be arranged in front of the holding portion.

[0020] According to the above configuration, in a frontal collision or the like, when a structure approaches from the front, since the connecting portion of the bracket is located in front of the holding portion, the bracket receives a load at the connecting portion and rotates backward, thereby moving the harness held by the holding portion backward to avoid contact with the structure.

[0021] The bracket described above may further have a fitting portion that protrudes from the rear of the joint towards the center of the power unit in the vehicle width direction, allowing it to contact the power unit from above.

[0022] According to the above configuration, when the bracket receives a load from the front, the fitting portion interferes with the power unit, thereby enabling the bracket to be kept in its correct position and orientation.

[0023] The bracket described above may be mounted in the area below the first electrical component of the power unit.

[0024] With the above configuration, even if a frontal structure moves closer to the bracket during a frontal collision, the first electrical component can receive the structure, thereby protecting the bracket and harness. [Examples]

[0025] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. The dimensions, materials, and other specific numerical values ​​shown in these embodiments are merely illustrative to facilitate understanding of the invention and do not limit the present invention unless otherwise specified. In this specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to avoid redundant explanations, and elements not directly related to the present invention are omitted from the illustrations.

[0026] Figure 1 is a diagram showing an overview of a vehicle harness holding structure (harness holding structure 100) according to an embodiment of the present invention. Figure 1(a) is a schematic diagram showing the power unit 102 of the harness holding structure 100.

[0027] In the following, in Figure 1 and all other drawings of this application, the front-rear direction of the vehicle is illustrated by arrows F (Forward) and B (Backward), the left-right direction in the vehicle width direction is illustrated by arrows L (Leftward) and R (Rightward), and the up-down direction of the vehicle is illustrated by arrows U (Upward) and D (Downward).

[0028] The power unit 102 is a vehicle drive source, such as a motor. The power unit 102 is mounted in a power unit mounting room formed in the front of the vehicle.

[0029] The bracket 104 is a component that holds the harness 106 (see Figure 3(b)) which is routed around the power unit 102. The bracket 104 is mounted so as to extend upward from the side of the power unit 102. In this harness holding structure 100, the configuration of the bracket 104 is designed to suppress damage to the harness 106 in the event of an impact such as a frontal collision.

[0030] Figure 1(b) is an enlarged view of the bracket 104 in Figure 1(a). The bracket 104 is mainly a metal component, with a resin gripping member 108 attached to its upper end, which grips the harness 106 (see Figure 3(b)) via the gripping member 108.

[0031] Figure 2 is a perspective view showing the bracket 104 from Figure 1(b) from various directions. Figure 2(a) is a view of the bracket 104 from the same rear right side of the vehicle as in Figure 1(b).

[0032] The lower end of the bracket 104, the connecting portion 110, is the part that connects to the power unit 102. The connecting portion 110 is composed of a through hole 112 and a fastener 114 (see Figure 1(b)) which is realized by a bolt or the like.

[0033] The retaining portion 116 at the upper end of the bracket 104 is the part that holds the harness 106 via the gripping member 108 (see Figure 3(b)). The retaining portion 116 is composed of a support surface 118 that supports the gripping member 108, and a through hole 120 into which the gripping member 108 fits.

[0034] The bracket 104 has a side flange 122 formed along its rear side edge. The side flange 122 is formed by bending the side edge from the lower end to the upper end of the bracket 104, thereby increasing the rigidity of the bracket 104.

[0035] Figure 2(b) shows the bracket 104 from Figure 2(a) as viewed from the front right of the vehicle.

[0036] The bracket 104 has a side flange 124 formed along its front side edge. The side flange 124 is also formed by bending the side edge from the lower end to the upper end of the bracket 104, thereby increasing the rigidity of the bracket 104.

[0037] Figure 2(c) is a view of the bracket 104 shown in Figure 2(b) from the front.

[0038] The first vertical wall portion 126 is a vertical wall-like portion that extends upward from the joint portion 110. The first vertical wall portion 126 is formed in the range from the joint portion 110 to the first bent portion 128.

[0039] The first bend 128 is a bending point between the first vertical wall 126 and the horizontal frame 130. The first bend 128 is formed so that the horizontal frame 130 extends horizontally, but the angle is not limited.

[0040] The horizontal section 130 is a horizontal plate-like portion formed in the area between the first vertical wall section 126 and the holding section 116. The horizontal section 130 is bent towards the center in the vehicle width direction of the power unit 102 (see Figure 3(b)) by the first bending section 128 from the first vertical wall section 126, and extends almost horizontally.

[0041] The second bend 132 is a bending point between the horizontal section 130 and the second vertical wall section 134. The second bend 132 is formed such that the second vertical wall section 134 extends vertically, but the angle is not limited.

[0042] The second vertical wall portion 134 is a vertical wall-like portion formed in the area between the horizontal frame portion 130 and the holding portion 116. The second vertical wall portion 134 extends upward from the horizontal frame portion 130 in a curved manner.

[0043] As shown in Figure 2(b), a first bead 136 is formed on the outer corner side of the first bend 128. The first bead 136 is formed in a bulging state extending from the first vertical wall portion 126 to the horizontal portion 130, thereby increasing the rigidity of the first bend 128.

[0044] A second bead 138 is formed on the outer corner side of the second bend 132. The second bead 138 is formed in a bulging state extending from the horizontal section 130 to the second vertical wall section 134, thereby increasing the rigidity of the second bend 132.

[0045] The bracket 104 with the above configuration has a first vertical wall portion 126 extending in the vertical direction and a horizontal frame portion 130 extending in the horizontal direction, thereby ensuring rigidity against loads in both the vertical and horizontal directions. Furthermore, the bracket 104 has a second vertical wall portion 134 extending in the vertical direction, thereby ensuring even greater rigidity against loads in the vertical direction. With this shape of bracket 104, it is possible to suitably hold the harness 106 (see Figure 3(b)) by utilizing its high rigidity.

[0046] Figure 3 shows the harness holding structure 100 of Figure 1(a) as viewed from the front. Figure 3(a) shows the entire power unit 102 of Figure 1(a) as viewed from the front.

[0047] The first electrical component 140 is positioned above the power unit 102. The first electrical component 140 can be embodied, for example, as a power converter that converts power supplied from a battery.

[0048] The second electrical component 142 is located on the right side of the power unit 102 in the vehicle width direction. The second electrical component 142 can be implemented, for example, as a compressor used in a cooling system for the vehicle interior or equipment.

[0049] The harness 106 is routed between the first electrical component 140 and the second electrical component 142 within the power unit mounting room. The harness 106 extends from above the power unit 102 toward the right.

[0050] Figure 3(b) is a magnified view of the area around bracket 104 in Figure 3(a).

[0051] The coupling portion 110 of the bracket 104 is coupled to the side of the power unit 102 on the side of the second electrical component 142 (see Figure 3(a)).

[0052] The holding portion 116 (see Figure 2(c)) holds the harness 106 at a higher position than the power unit 102 via the gripping member 108. At this time, the holding portion 116 is located to the left in the vehicle width direction relative to the harness 106.

[0053] Figure 4 is an enlarged view of the bracket 104 in Figure 3(b). In Figure 4, the harness 106 is virtually shown with a dashed line.

[0054] The bracket 104 is positioned relative to the harness 106, extending from below and inward in the vehicle width direction of the power unit 102.

[0055] When the bracket 104 receives a load from the front of the vehicle, it may rotate backward around the fixing device 114 of the connecting portion 110 (see Figure 1(b)) as an axis. In this embodiment, even when the bracket 104 rotates back and forth around the connecting portion 110 as the center of rotation, its trajectory does not overlap with the harness 106.

[0056] As shown in Figure 4, when viewed from the front of the vehicle, the bracket 104 is shaped so that it does not overlap the harness 106. Even when the bracket 104 is rotated in the front-rear direction of the vehicle with the connecting portion 110 as the pivot point, its edges do not come into contact with the harness 106.

[0057] In the harness holding structure 100 of this embodiment, if the bracket 104 is subjected to a load from the front, for example, due to a frontal collision, contact between the edge of the tilted bracket 104 and the harness 106 can be prevented, thereby preventing damage to the harness 106. Therefore, according to the harness holding structure 100 of this embodiment, the harness 106 can be held securely even in emergencies.

[0058] In this embodiment, the bracket 104 has a holding portion 116 positioned closer to the center of the power unit 102 in the vehicle width direction than the connecting portion 110. More specifically, the holding portion 116 is formed at a distance D1 away from the center of the power unit 102 in the vehicle width direction compared to the connecting portion 110.

[0059] The retaining portion 116 is positioned closer to the center of the power unit 102 than the connecting portion 110. The power unit 102 exhibits high rigidity during frontal collisions, etc. Therefore, by positioning the retaining portion 116 towards the center of the power unit 102, the rigidity of the power unit 102 can be used to distribute the load that may be applied to the retaining portion 116. Thus, by positioning the retaining portion 116 towards the center of the power unit 102, deformation of the retaining portion 116 can be suppressed, and the harness 106 can be held appropriately.

[0060] Figure 5 shows the harness holding structure 100 of Figure 3(a) viewed from above. Figure 5(a) shows the power unit 102 viewed from above, with the first electrical component 140 of Figure 3(a) visible through it.

[0061] The bracket 104 is mounted on the upper right side in the vehicle width direction of the power unit 102, in an area located below the first electrical component 140.

[0062] Figure 5(b) is a magnified view of the area around bracket 104 in Figure 5(a).

[0063] The retaining portion 116 is roughly plate-shaped, but its shape is inclined so that the surface facing the harness is facing backward. More specifically, the retaining portion 116 is inclined so that its rear end 144b is located towards the center of the vehicle width direction of the power unit 102 compared to its front end 144a.

[0064] For example, the holding portion 116 has a shape in which a virtual line L2 along the support surface 118 (see Figure 2(b)) is inclined with respect to a virtual line L1 extending in the longitudinal direction of the vehicle, such that it forms an angle α1 inward in the vehicle width direction of the power unit 102.

[0065] As shown in Figure 6(b), which will be described later, the holding portion 116 holds the harness 106 in the front-rear direction via the gripping member 108. At this time, as shown in Figure 5(b), the holding portion 116 is shaped to be inclined toward the center in the vehicle width direction of the power unit 102, so that the harness 106 can be routed more toward the center in the vehicle width direction of the power unit 102 by the holding portion 116. Therefore, the holding portion 116 makes it possible to improve the degree of freedom in routing the harness 106 according to its inclination.

[0066] Figure 6 shows the harness holding structure 100 of Figure 3(a) as viewed from the right side in the vehicle width direction. Figure 6(a) shows the entire power unit 102 of Figure 3(a) as viewed from the right side.

[0067] As described above, the first electrical component 140 is located above the power unit 102 within the power unit mounting room. The bracket 104 is attached to the power unit 102 in the area below the first electrical component 140.

[0068] Figure 6(b) is a magnified view of the area around bracket 104 in Figure 6(a). Bracket 104 is attached to the side of power unit 102 by fixing part 110. The retaining part 116 (see Figure 7) is positioned to the left in the vehicle width direction (towards the rear in Figure 6(b)) relative to harness 106.

[0069] Figure 7 is an enlarged view of bracket 104 in Figure 6(b).

[0070] In Figure 7, a dashed line shows a structure S1 approaching the power unit 102 from the front in the event of a frontal collision. In particular, if the collision object is located at a high position relative to the vehicle equipped with the harness holding structure 100, the structure S1 may approach the power unit 102 from diagonally above and in front.

[0071] When the bracket 104 receives a load from the front of the vehicle, it can move to rotate along a trajectory R1 with the joint 110 as the center of rotation. This rotation allows it to deflect the load from the front and effectively hold the harness 106.

[0072] When viewed from the side, the bracket 104 is positioned such that its upper end is slightly tilted backward relative to its lower end. Therefore, the lower end connecting portion 110 is positioned approximately D2 forward of the upper end retaining portion 116.

[0073] The bracket 104 has a holding portion 116 positioned behind the connecting portion 110, which allows it to avoid contact between the harness 106 (see Figure 6(b)) and the structure S1 when the structure S1 approaches from the front in a frontal collision or the like. Also, because the connecting portion 110 is positioned in front of the holding portion 116, the connecting portion 110 is subjected to a load from the front before the holding portion 116. Therefore, the bracket 104 can be tilted backward with the connecting portion 110 as the center of rotation.

[0074] As described above, the bracket 104 has a joint 110 positioned in front of the holding portion 116, making it more susceptible to load. As a result, the joint 110 receives the load before the holding portion 116, causing it to rotate to some extent backward. This allows the bracket 104 to move the harness 106 (see Figure 6(b)) held by the holding portion 116 backward, thereby avoiding contact between the harness 106 and the structure S1.

[0075] The bracket 104 is mounted in the area below the first electrical component 140 of the power unit 102. With this configuration, even if the front structure S1 moves towards the bracket 104 in the event of a frontal collision, the first electrical component 140 can receive the structure S1, thereby protecting the bracket 104 and the harness 106.

[0076] Figure 8 is a cross-sectional perspective view of the bracket 104 in Figure 7. Figure 8 shows the AA cross-section of the bracket 104 in Figure 7, viewed from the right rear of the vehicle.

[0077] The bracket 104 has a fitting portion 146 on the rear side of the lower end joint portion 110. The fitting portion 146 is a protruding part that projects towards the center in the vehicle width direction of the power unit 102. A flange-shaped projection 148 is provided on the side of the power unit 102. The fitting portion 146 can contact the projection 148 of the power unit 102 from above.

[0078] The fitting portion 146 contacts the power unit 102 from above, enabling the bracket 104 to maintain the slightly rearward tilted position shown in Figure 7.

[0079] Furthermore, the fitting portion 146 interferes with the power unit 102 when the bracket 104 receives a load from the front due to a frontal collision or the like, thereby enabling the bracket 104 to maintain its correct position and orientation. At this time, the fitting portion 146 can also deform due to the load from the front. In other words, the fitting portion 146 does not completely resist the load, but is able to rotate the bracket 104 so that it tilts backward while deforming, thereby deflecting the load.

[0080] Figure 9 shows a modified example (bracket 200) of bracket 104 in Figure 2(c).

[0081] The modified bracket 200 has a chamfered portion 202. The chamfered portion 202 is formed by chamfering the outer corner of the bending point between the first vertical wall portion 126 and the horizontal portion 130. A second bead 204 is provided on the chamfered portion 202, extending from the first vertical wall portion 126 to the horizontal portion 130, to ensure rigidity.

[0082] The bracket 200 has a chamfered portion 202, which causes its shape to recede from the harness 106 in Figure 4 towards the power unit 102. In other words, the bracket 200 can maintain a greater distance from the harness 106 held by the retaining portion 116. Therefore, the bracket 200 can also reduce the possibility of contact with the harness 106 when it rotates back and forth around the connecting portion 110 as the center of rotation in a frontal collision, and can suitably hold the harness 106.

[0083] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but it goes without saying that the present invention is not limited to these examples. It is clear to those skilled in the art that various modifications or alterations can be conceived within the scope of the claims, and these will naturally also fall within the technical scope of the present invention.
