Description

Technical Field

[0001] The present invention relates to a ventilation structure for vehicles.

Background Art

[0002] In order to cool in-vehicle components such as capacitors and radiators arranged inside, it is necessary to provide openings such as a front grille for introducing wind from the outside of the vehicle in predetermined members such as the front bumper of the vehicle and reinforcing members for reinforcing the same.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in particular, in box-type vehicles where the passenger compartment is long vertically and short front to back, it may be necessary to route the cable-like material inside an opening in a component such as the front bumper. In such cases, the cable may reduce the ventilation performance of the opening, and it also becomes easier for malicious actors to illegally access the cable through the opening.

[0006] In view of these problems, the present invention aims to provide a vehicle ventilation structure that ensures the ventilation performance of an opening provided in a predetermined member for ventilation between the inside and outside of the vehicle, even when a cable-like material is routed on the inside of the opening, and also prevents unauthorized access to the cable-like material from the outside through the opening. [Means for solving the problem]

[0007] To solve the above problems, a typical configuration of the present invention is a vehicle ventilation structure comprising a predetermined member having an opening for ventilation inside and outside a vehicle, a ventilation section protruding from the opening into the vehicle interior and forming a flow path for ventilation, and a cable-like body arranged on the vehicle interior side of the above member, characterized in that the cross-section of the cable-like body does not, overall, overlap with the orthogonal projection image of the ventilation opening on the vehicle interior side of the ventilation section onto the vehicle interior side. [Effects of the Invention]

[0008] According to the present invention, even when a cable-like body is routed on the interior side of an opening provided in a predetermined member for ventilation between the inside and outside of the vehicle, it is possible to provide a vehicle ventilation structure that ensures the ventilation performance of the opening and prevents unauthorized access to the cable-like body from the outside through the opening. [Brief explanation of the drawing]

[0009] [Figure 1] This is a front view of a front bumper that constitutes an embodiment of the vehicle ventilation structure according to the present invention. [Figure 2] Figure 1 is a rear view of the front bumper. [Figure 3] Figure 2 is a magnified view of a portion of the upper panel. [Figure 4] Figure 3 is an enlarged view of the ventilation area. [Figure 5] This figure shows the protective cover in Figure 4(a). [Figure 6] This figure shows a modified example of the protective cover shown in Figure 3. [Figure 7] Figure 3 is a cross-sectional view of the ventilation section. [Figure 8] Figure 4(a) is a cross-sectional view of the CC section of the ventilation area. [Figure 9] Figure 7 is a schematic diagram showing a modified example of the ventilation section and harness. [Modes for carrying out the invention]

[0010] One embodiment of the present invention provides a vehicle ventilation structure comprising a predetermined member having an opening for ventilation inside and outside a vehicle, a ventilation section protruding from the opening toward the interior of the vehicle and forming a flow path for ventilation, and a cable-like body arranged on the interior side of the member, characterized in that the cross-section of the cable-like body does not, in whole, overlap with the orthogonal projection of the ventilation opening on the interior side of the ventilation section toward the interior of the vehicle.

[0011] According to the present invention, by adding a ventilation section to the interior side of an opening provided in a predetermined member, a flow path for ventilation is formed, and the dispersion of air is suppressed. After arranging the air flow path in this way, the cable is routed offset away from the flow path so that the cross-section of the cable does not overlap overall with the orthogonal projection image of the ventilation opening on the interior side of the ventilation section. With this configuration, even when it is necessary to route the cable on the interior side of an opening provided in the above member, the cable is prevented from obstructing ventilation. At the same time, it is also prevented from accessing the cable through the opening from outside the vehicle.

[0012] The ventilation structure for the vehicle may further include a protective cover having a smoothly formed surface that covers at least the side of the cable-like body facing the ventilation portion.

[0013] According to the above configuration, even if there is access to the cable from outside the vehicle, the protective cover protects the cable, so it is possible to prevent the cable from being damaged. Also, even if a part of the air passing through the ventilation port of the ventilation part flows toward the protective cover side, the air smoothly flows along the smoothly formed surface of the protective cover, so it is possible to suppress the occurrence of turbulent flow or the like when the air hits the protective cover and the reduction of the blowing efficiency.

[0014] The wall on the cable side of the ventilation part may be inclined so as to approach the facing wall as it goes toward the inside of the vehicle. According to such a configuration, the air passing through the ventilation part is guided by the inclined wall, and it is more reliably prevented from being blocked by the cable.

[0015] The ventilation part may be cut out by the fact that the wall on the cable side thereof terminates on the outside of the vehicle than the facing wall.

[0016] According to such a configuration, the ventilation part can reduce the area facing the cable by the amount by which it is cut out, and it is possible to prevent the ventilation part and the cable from coming into contact with each other due to vibrations during running or the like and the cable from being damaged. That is, it is possible to secure a routing space for the cable.

[0017] Also, when the ventilation part is used for intake, the air flowing so as to peel off from the cut-out part of the ventilation part can be blown toward the inside of the vehicle along the cable.

[0018] The ventilation part may have a smaller cross-sectional area as it goes toward the inside of the vehicle. According to such a configuration, when the ventilation part is used for intake, the flow velocity of the air flowing from outside the vehicle to the inside of the vehicle through the ventilation part increases, so the air becomes more likely to flow linearly along the flow path formed by the ventilation part and is easily guided to the inside of the vehicle while avoiding the cable. That is, it is more effectively prevented that the ventilation (intake) is obstructed by the cable.

[0019] The ventilation structure for the vehicle further includes a vehicle body frame member that is farther from the ventilation port on the inside of the vehicle of the ventilation part than the cable when facing the above opening, and the cable is preferably routed along the vehicle body frame member.

[0020] By routing the cable-like structure along the vehicle frame members that are further away from the ventilation section than the cable itself, when the ventilation section is used for intake, the airflow can be more stably delivered to the interior of the vehicle along the cable without obstructing the airflow that separates from the cutouts in the ventilation section. In other words, the efficiency of air delivery can be increased. Furthermore, because the cable-like structure is routed along the robust vehicle frame members, the support rigidity of the cable-like structure is increased, and movement of the cable-like structure in a direction that obstructs airflow can be suppressed.

[0021] The ventilation structure for the vehicle further includes a partition that separates the above-mentioned opening on the outside of the vehicle, and it is preferable that the cutout portion of the ventilation section overlaps with the orthogonal projection of the partition onto the inside of the vehicle.

[0022] By positioning the ventilation section with a cutout behind the partition in this way, when the ventilation section is used for intake, air can flow more easily to the back of the partition section, where air would normally not flow easily. In addition, the partition section can more effectively prevent access to the cable-like material from outside the vehicle.

[0023] The ventilation structure for the vehicle further includes a partition that separates the above-mentioned opening on the outside of the vehicle, and the orthogonal projection image of the ventilation opening on the inside of the vehicle of the ventilation section is divided into a first region where the area occupied by the partition is relatively large and a second region where this proportion is relatively small, by a straight line perpendicular to the cord-like body, and it is preferable that the dimensions of the first region in the direction in which the straight line extends are larger than those of the second region.

[0024] In the first region, the proportion of the area occupied by the partition is relatively large, which prevents access to the cable-like structure from outside the vehicle, but reduces the ventilation efficiency. Therefore, as described above, the dimensions of the first region in the direction in which the straight line separating the first and second regions extends are made larger than those of the second region, thereby restoring the ventilation efficiency of the first region.

[0025] The above-mentioned cord-like structure is preferably routed so that it moves away from the vent towards the interior of the vehicle in the second region of the vent on the interior side of the ventilation section, rather than in the first region of the vent on the interior side of the vehicle.

[0026] In the second region of the ventilation opening on the interior side of the vehicle, the proportion of the area occupied by the partition is smaller than in the first region, making it easier to access the cable-like material from outside the vehicle. Therefore, as described above, the cable-like material is routed so that it is further inward from the ventilation opening in the second region than in the first region of the ventilation opening, making it difficult for tools for unauthorized access, such as cutters, inserted from the second region to reach the cable-like material. Furthermore, because the dimensions of the second region are smaller than those of the first region in the direction in which a straight line perpendicular to the cable-like material extends, it is difficult for a malicious actor to move a tool for unauthorized access in the same direction. [Examples]

[0027] 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.

[0028] Figure 1 is a front view showing an embodiment of the vehicle ventilation structure according to the present invention. In Figure 1 and all other drawings, the front-rear direction of the vehicle is indicated by arrows F (Forward) and B (Backward), respectively; the left and right directions in the vehicle width direction are indicated by arrows L (Leftward) and R (Rightward), respectively; and the up and down directions are indicated by arrows U (Upward) and D (Downward), respectively.

[0029] (Front pump) Figure 1(a) is a front view of a front bumper 100 that constitutes an embodiment of a vehicle ventilation structure. The front bumper 100 in Figure 1(a) is an exterior panel that constitutes the design surface of the vehicle and includes a lower panel 102 which is its main body, an upper panel 104 provided above the lower panel 102, and a bumper reinforcing member 105 that is connected to the back side (inside the vehicle) of the lower panel 102 and the upper panel 104 and reinforces them. A ventilation area 106 is provided in the upper panel 104.

[0030] Figure 1(b) is an enlarged view of the upper panel 104 in Figure 1(a). The ventilation area 106 of the upper panel 104 functions as a grille by forming an opening 107 divided into multiple meshes (openings) 107A, 107B, 107C, 107D, and 107E by a staggered partition 110. The area outside the ventilation area 106 is not a mesh, but the non-ventilated panel surface of the upper panel 104.

[0031] Figure 1(c) is a magnified view of the area around the opening 108 of the bumper reinforcement member 105 after removing the upper panel 104 in Figure 1(b). When the upper panel 104 is removed in this way, the partition portion 110 that separates the ventilation area 106 of the upper panel 104 and is integrated with the upper panel 104 is also removed. Figure 1(c) shows the bumper reinforcement member 105 that is exposed at that time, and the opening 108 provided therein.

[0032] In this embodiment, the ventilation area 106 and the opening 108 are intake ports that exclusively introduce wind (air) from outside the vehicle into the interior and supply air to onboard components (not shown) such as an internal combustion engine located behind the front bumper 100. However, the present invention may also be applied to exhaust ports that exhaust air from inside the vehicle to the outside.

[0033] Figure 2 is a rear view of the front bumper 100 shown in Figure 1. As shown in Figure 2, a latch structure 112 is provided on the rear side of the upper panel 104, which opens and closes the front hood by engaging and disengaging with a striker (both not shown) provided on the front hood. A harness 114, which is a cable-like body, is connected to the latch structure 112.

[0034] (Harness) Figure 3 is a magnified view of a portion of the upper panel 104 in Figure 2. The harness 114 is routed near the opening 108 provided in the bumper reinforcement member 105, specifically below the opening 108, across the vehicle width direction (left-right direction).

[0035] As shown in Figure 3, the bumper reinforcement member 105 is equipped with a ventilation section 116 that protrudes inward from an opening 108 formed in a location corresponding to the ventilation area 106 of the upper panel 104. The ventilation section 116 is a member that guides the air introduced from the opening 108 and forms a flow path for ventilation. The ventilation section 116 has an air opening 118 on the interior side of the vehicle, from which it guides air to the rear onboard components (not shown). The ventilation section 116 has a shape like a square pyramid cut before reaching its apex, and is a hollow solid in which the air opening 118 corresponding to the cut surface and the opening 108 corresponding to the bottom surface are connected by upper, lower, left, and right walls 116A, 116B, 116C, 116D (Figure 4).

[0036] In this embodiment, the bumper reinforcement member 105 corresponds to the "predetermined member" described in the claims, but the "predetermined member" may be provided on exterior panels such as the upper panel 104 or on exterior parts of the vehicle such as the grille and air guide. In other words, the ventilation section 116 may be provided on such exterior panels or exterior parts of the vehicle.

[0037] In this embodiment, the ventilation section 116 has upper, lower, left, and right walls 116A, 116B, 116C, and 116D, but some of the walls that partition the flow path may be constructed using the outer surfaces of electrical components or other in-vehicle components arranged along the flow path.

[0038] Figure 4 is an enlarged view of the ventilation section 116 in Figure 3. Figure 4(a) shows the routing of the harness 114, and Figure 4(b) is Figure 4(a) with the harness 114 removed. Figure 7 is a cross-sectional view of the ventilation section 116 in Figure 3, where Figure 7(a) is the AA cross-sectional view and Figure 7(b) is the BB cross-sectional view, with the latter showing the cross-section of the ventilation section 116.

[0039] As shown in Figure 7(b), the harness 114 is routed offset away from the flow path, i.e., downward from the ventilation section 116, so that the cross-section of the harness 114 does not overlap overall with the orthogonal projection image 118A of the ventilation opening 118 on the vehicle side of the ventilation section 116 onto the vehicle side.

[0040] To explain again using Figure 4(a), the orthographic projection image 118A of the vent 118 onto the interior of the vehicle is none other than the outline of the vent 118 shown by the thick line. The harness 114 slightly overlaps the outline of the vent 118 (orthographic projection image 118A) at its upper edge, but does not overlap overall, and has a portion that protrudes downward from the outline of the vent 118 (orthographic projection image 118A). In other words, as shown in Figure 7(b), the cross-section of the harness 114 does not overlap overall with the orthographic projection image 118A of the vent 118 onto the interior of the vehicle. For this reason, for example, when a viewer's eyes are directly facing the opening 108, the harness 114 is less likely to enter the viewer's field of vision.

[0041] In this embodiment, by adding a ventilation section 116 to the opening 108 provided in the bumper reinforcement member 105, a flow path for ventilation is formed, suppressing the dispersion of air. After aligning the direction of the air flow path in this way, the harness 114 is routed offset away from the flow path, i.e., below the ventilation section 106, so that the cross-section of the harness 114 does not overlap overall with the orthogonal projection image 118A of the ventilation opening 118 onto the interior side of the vehicle. Therefore, when a viewer is facing the ventilation area 106 from the outside of the vehicle, the ventilation section 116 obstructs the viewer's view of the harness 114 side while preventing access to the harness 114 side. With this configuration, even if the harness 114 must be routed on the interior side of the opening 108, the harness 114 is prevented from obstructing ventilation. At the same time, access to the harness 114 from outside the vehicle through the opening 108 is also prevented. Furthermore, when a viewer's eyes are facing the opening 108 directly from outside the front bumper 100, the harness 114 is less likely to be in the viewer's field of vision, which has the advantage of making it difficult for the viewer to grasp the position of the harness 114.

[0042] In Figure 7(b), it is acceptable to route the harness 114 further downward, so that the entire cross-section of the harness 114 extends beyond the orthographic projection 118A. This is because it satisfies the condition that "they do not overlap overall." On the other hand, in Figure 7(b), if the harness 114 is routed upward, so that the entire cross-section of the harness 114 overlaps with the orthographic projection 118A, this cannot be considered an embodiment of the present invention.

[0043] In this embodiment, the harness 114 is routed on the lower side of the ventilation section 116, but it may also be routed on the upper or right side.

[0044] Figure 4(c) shows a modified version of the ventilation section 116 in Figure 4(b). Compared to the ventilation section 116 in Figure 4(b), the modified ventilation section 117 in Figure 4(c) does not have an upper wall 116A. That is, while the ventilation section 116 has a frame-shaped closed cross section, the ventilation section 117 has a U-shaped cross section and a larger ventilation opening 119. However, even with this shape, the ventilation section 117 still has a lower wall 116B through which the harness 114 is routed, thus preventing the harness 114 from obstructing ventilation and simultaneously preventing access to the harness 114 from outside the vehicle through the opening 108.

[0045] (Bumper reinforcement member) The bumper reinforcement member 105, which has a ventilation section 116 as shown in Figure 4, is made of resin and has higher rigidity than the upper panel 104 and lower panel 102. The bumper reinforcement member 105 is also supported by the cross member 128, which will be described later, and reinforces and supports the upper panel 104 and lower panel 102 to prevent deformation and sagging. In this way, because the frame-shaped section 116 is provided on the panel reinforcement section 105, which has higher rigidity than the exterior panel on the back side of the exterior panel (upper panel 104 and lower panel 102), deformation of the frame-shaped section 116 can also be suppressed. Furthermore, the reduction in rigidity of the bumper reinforcement member 105 itself, which occurred due to the formation of the opening 108, is also suppressed by providing the ventilation section 116.

[0046] (Protective cover) As shown in Figure 4(a), the harness 114 is covered by a protective cover 120. Figure 5 shows the protective cover 120 in Figure 4(a). Figure 5(a) is a perspective view of the protective cover 120, and Figure 5(b) is a cross-sectional view showing the process of attaching the protective cover 120 to the harness 114. As shown in Figure 5(a), the protective cover 120 is molded from a hard resin with a smooth cylindrical surface and covers the outer circumferential surface of the harness 114. In this embodiment, the protective cover 120 is cylindrical in this way, but it is sufficient that it covers at least the surface of the harness 114 on the ventilation portion 116 side.

[0047] As shown in Figure 5(a), the protective cover 120 has a notch 126 formed from one end 122 to the other end 124. Then, as shown in Figure 5(b), the notch 126 of the protective cover 120 is opened to accommodate the harness 114.

[0048] With the above configuration, even if the harness 114 is accessed from outside the vehicle, the protective cover 120 protects the harness 114, preventing damage to the harness 114. Furthermore, even if the air passing through the vent 118 of the ventilation section 116 hits the protective cover 120, it flows smoothly along the smoothly formed surface of the protective cover 120, thus suppressing the generation of turbulence and other issues that would reduce the airflow efficiency.

[0049] Figure 6 shows a modified example of the protective cover 120 in Figure 3. As shown in Figure 6, compared to the protective cover 120, the protective cover 120A in this modified example passes under the vent 118 of the ventilation section 116 and extends to the left side to the back of the connecting member 129, which will be described later. By routing the harness 114 upward from the extended protective cover 120A in this way, access to the parts of the harness 114 that were not covered by the protective cover 120 through the opening 108 can be prevented more effectively.

[0050] (Ventilation area) As shown in Figure 7(b), the wall 116B of the ventilation section 116 on the harness 114 side is inclined so that it approaches the opposing wall 116A as it moves towards the interior of the vehicle. With this configuration, the air passing through the ventilation section 116 is guided in the direction indicated by the arrow 134 by the inclined wall 130, and is more reliably prevented from being blocked by the harness 114.

[0051] As shown in Figures 7(a) and 7(b), the ventilation section 116 has a cutout 136 because its harness 114 side wall 130 ends on the outside of the vehicle side compared to the opposing wall 132.

[0052] With this configuration, the area of ​​the ventilation section 116 that comes into contact with the harness 114 is reduced by the amount of the cutout 136, preventing the harness 114 (protective cover 120) from coming into contact with the ventilation section 116 due to vibrations during driving, which could damage the harness 114 or generate abnormal noises. In other words, space for routing the harness 114 and the protective cover 120 can be secured.

[0053] Furthermore, when the ventilation section 116 is used for intake, air can be blown into the vehicle interior along the harness 114, flowing in a manner that separates from the notched portion 136 of the ventilation section 116.

[0054] As shown in Figure 4(b), the cutout portion 136 of the ventilation section 116 has a portion 136a that extends in the vehicle width direction while shortening in the vertical direction. This portion 136a also ensures ventilation and prevents unauthorized access.

[0055] As is clear from Figures 7(a) and 7(b), the cross-sectional area of ​​the ventilation section 116 decreases as it moves towards the interior (rear) of the vehicle. With this configuration, when the ventilation section 116 is used for intake, the airflow velocity of the air flowing from outside to inside the vehicle through the ventilation section 116 increases, so the air flows more linearly along the flow path formed by the ventilation section 116, and is more easily guided towards the interior of the vehicle, avoiding the harness 114. In other words, obstruction of ventilation (intake) by the harness 114 is more effectively prevented.

[0056] (Vehicle frame components) As shown in Figures 2 and 3, the vehicle body frame member 135 is formed by a cross member 128 extending in the vehicle width direction, a cross member 131 positioned above the cross member 128 and extending in the vehicle width direction, a vertical member 133 extending in the vertical direction that connects the cross members 128 and 131, and a vertically extending connecting member 129 that connects the cross members 128 and 131 at a location corresponding to the latch structure 112. The vehicle body frame member 135 has a frame structure as shown by the dashed line.

[0057] The latch mechanism 112 is supported by the cross member 131 and the connecting member 129. The front bumper 100 is fixed to the cross member 131 via a flange (not shown) provided at its upper end, and is further supported by the cross member 128 via a bumper reinforcing member 105.

[0058] As shown in Figures 4(a) and 7(a)(b), the cross member 128 is positioned offset from the airflow path relative to the vent 118 on the vehicle side of the ventilation section 116 (in this embodiment, it is positioned below the vent 118). The harness 114 is routed along the cross member 128 and fixed to the cross member 128 by supports 137 and 139. Note that in Figure 4(b), both the harness 114 and the cross member 128 are omitted from the illustration.

[0059] By routing the harness 114 along the cross member 128, which is further away from the ventilation section 116 than the harness 114, when the ventilation section 116 is used for intake, the air 138 that flows away from the cutout section 136 of the ventilation section 116 can be supplied more stably to the interior of the vehicle along the harness 114 without obstructing it. In other words, the efficiency of air supply can be increased. Furthermore, since the harness 114 is routed and fixed to the highly rigid cross member 128 that constitutes the above-mentioned vehicle body frame member 135, the support rigidity of the harness 114 is increased, and displacement of the harness 114 in a direction that obstructs the air can be suppressed.

[0060] Furthermore, a connecting member 129 extends vertically adjacent to the partition 110, with a 112 provided on the upper part of the connecting member 129. The harness 114 is routed below the ventilation section 116 and then routed on the interior (back) side of the connecting member 129. As a result, unauthorized access to the area between the latch structure 112 and the ventilation section 116 in the harness 114 is also difficult.

[0061] As shown in Figure 3, the bumper reinforcement member 105 is fixed to the cross member 131 at its upper part by a flange (not shown) and supported at its lower part by the connecting member 129 via brackets 141 and 143 (Figure 8). With this configuration, the front bumper 100 (lower panel 102 and upper panel 104) is supported by the vehicle body frame member 135 via the bumper reinforcement member 105, thereby providing stable support for the front bumper 100.

[0062] (Partition section) As shown in Figure 1(b), the front bumper 100 further includes a partition portion 110 that partitions the ventilation area 106 of the upper panel 104 on the outside of the vehicle, and at the same time partitions the opening 108 of the bumper reinforcing member 105. As shown in Figures 4(b) and 7(b), at least a portion of the cutout portion 136 of the ventilation area 116 overlaps with the orthogonal projection image 118A of the partition portion 110 onto the inside of the vehicle. That is, when the viewer's eye is facing the ventilation area 106 directly, the cutout portion 136 is located on the back side of the partition portion 110.

[0063] By positioning the cutout portion 136 of the ventilation section 116 behind the partition section 110 in this way, when the ventilation section 116 is used for intake, air can flow more easily to the back (rear) side of the partition section 110, where air would normally not flow easily. In addition, by providing the partition section 110, access to the harness 114 from outside the vehicle can be prevented more effectively.

[0064] (Ventilation opening) As shown in Figure 4(b), the orthogonal projection of the vent 118 on the interior side of the ventilation section 116 (the outline of the vent 118 in Figure 4(b)) is divided into a first region 142 and a second region 144 by a virtual straight line 140 perpendicular to the harness 114. The first region 142 is the region where the area occupied by the partition section 110 is relatively large, and the second region 144 is where this proportion is relatively small. As shown in Figures 1(b) and 4(b), the dimensions of the first region 142 in the direction in which the straight line 140 extends are larger than those of the second region 144. That is, dimension D1 is larger than dimension D2.

[0065] In the first region 142, the proportion of the area represented by the partition 110 is relatively large, which prevents access to the harness 114 from outside the vehicle, but reduces the ventilation efficiency. Therefore, as described above, the ventilation efficiency of the first region 142 is restored by making the dimension D1 of the first region larger than the dimension D2 of the second region in the direction in which the straight line 140 separating the first region 142 and the second region 144 extends.

[0066] Figure 8 is a cross-sectional view of the CC of the ventilation section 116 in Figure 4(a). The harness 114 is routed such that in the second region 144 of the ventilation opening 118 on the vehicle side of the ventilation section 116, it moves further inward (rearward) from the ventilation opening 118 than in the first region 142.

[0067] Figure 8 shows dashed lines 145 and 147 extending rearward from the left and right walls 116C and 116D of the ventilation section 116. It is preferable for the protective cover 120 (rigid tube) to extend beyond these dashed lines 145 and 147, that is, to the outside of the ventilation opening 118 on the vehicle side of the ventilation section 116, in order to protect the harness 114 from unauthorized access.

[0068] Furthermore, of the left and right walls 116C and 116D of the ventilation section 116, the right wall 116D, which is opposite to the connecting member 129, is inclined inward (to the left) in the vehicle width direction as it moves towards the rear, as shown in Figure 8. This restricts unauthorized access of the harness 114 to the side opposite to the connecting member 129 (to the right).

[0069] In the second region 144 of the ventilation opening 118 on the vehicle interior side of the ventilation section 116, since the ratio indicated by the partition section 110 in its area is smaller than that of the first region 142, it has become easier to access the harness 114 from outside the vehicle. Therefore, as described above, the harness 114 is routed so as to be farther from the ventilation opening 118 toward the vehicle interior side (rearward) in the second region 144 than in the first region 142, making it difficult for tools for unauthorized access such as a cutter inserted from the second region 144 to reach the harness 114. Further, since the second region 144 has a smaller dimension (D2 < D1) in the direction in which the straight line 140 (FIG. 4(b)) orthogonal to the harness 114 extends than the first region 142, it has become difficult for a person with malicious intent to move a tool for unauthorized access inserted in the same direction.

[0070] FIG. 9 is a schematic view showing a modified example of the ventilation section 116 and the harness 114 in FIG. 7. FIGS. 9(a) and 9(b) are the first modified example and the second modified example, respectively, and elements common to both are indicated by the same reference numerals. Both the first modified example and the second modified example have a funnel-shaped ventilation section 216 whose vertical dimension increases toward the vehicle interior side, unlike the ventilation section 116 in FIG. 7. And the harnesses 214 and 215 are routed outside the vehicle with respect to the ventilation opening 218 of the ventilation section 216.

[0071] The difference between the first modified example and the second modified example is the degree of approach of the harnesses 214 and 215 to the ventilation section 216. In the first modified example of FIG. 9(a), the entire cross-section of the harness 214 overlaps with the front projection image 218A of the ventilation opening 218 on the vehicle interior side of the ventilation section 216 "toward the outside of the vehicle". An upper panel not shown in the figure is provided on the outside of the vehicle of the harness 214, and a lower wall 216B of the ventilation section 216 is provided on the inside of the vehicle of the harness 214, and the side of the harness 214 facing the ventilation section 216 is configured not to be exposed to the outside of the vehicle. On the other hand, in the second modified example of FIG. 9(b), the entire cross-section of the harness 215 protrudes from the front projection image 218A of the ventilation opening 218 toward the outside of the vehicle. Note that a part of the cross-section of the harnesses 214 and 215 may protrude from the front projection image 218A.

[0072] When using a flared ventilation section 216 in this manner, and routing harnesses 214 and 215 outside the vehicle beyond the ventilation opening 218, it does not matter whether the cross-sections of harnesses 214 and 215 overlap or not with the orthogonal projection image 218A of the ventilation opening 218 onto the outside of the vehicle. This is because harnesses 214 and 215 routed outside the vehicle beyond the ventilation opening 218 do not obstruct the ventilation through the ventilation opening 218.

[0073] Furthermore, the components covering the exterior of harnesses 214 and 215 are not limited to exterior panels such as upper panels, but may also be various in-vehicle components positioned around the exterior panels.

[0074] 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.

[0075] Furthermore, the present invention can be implemented by freely combining the inventions described in the claims and examples, regardless of the dependency relationships of the claims. [Industrial applicability]
