Description

TECHNICAL FIELD

[0001] The present application relates to an attachment structure for a vehicle solar panel. BACKGROUND

[0002] Japanese Unexamined Patent Application Publication No. 2015-229916 (JP 2015-229916 A) discloses an attachment structure for a solar panel that allows a solar panel to be attached to an attached member via a bracket. SUMMARY

[0003] A solar panel includes glass and a solar module that generates electricity using sunlight located on an inner side of the glass. Therefore, when an object of a certain type collides with the glass, a force is applied from the solar module to the attached member via the bracket, and a reaction force generated by the attached member can be transmitted to the solar module via the bracket. In this case, the solar module (solar battery) can be damaged, or disconnection can occur.

[0004] Here, a case in which the attachment structure for a solar panel of JP 2015-229916 A is applied to a vehicle is assumed. As described above, when a solar panel is attached to a vehicle, the likelihood of the above-described problem occurring increases.

[0005] The present application has been made in view of the above-described facts, and aims to obtain an attachment structure for a vehicle solar panel that can reduce the likelihood of a solar module of a solar panel provided on a vehicle flying away, and that does not easily receive a reaction force from a body structure member when the solar panel moves to the body structure member side.

[0006] The attachment structure for a vehicle solar panel according to the first aspect of the present application includes a body structure member that structures a portion of a vehicle body; a solar panel provided on the body structure member, the solar panel including glass exposed on an outer side of the vehicle body, and a solar module provided on a vehicle inner side surface of the glass; and a coupling member that couples the body structure member and the solar module. The coupling member includes a panel side attachment portion connected to the solar module; a body side attachment portion connected to the body structure member; and a connection portion that connects the panel side attachment portion and the body side attachment portion and has flexibility.

[0007] In the attachment structure for a vehicle solar panel according to the first aspect of the present application, the solar panel includes the glass exposed on the outer side of the vehicle body and the solar module provided on the vehicle inner side surface of the glass. Note that the glass used herein includes a covering member that coats a surface of the glass and has transparency.

[0008] Therefore, for example, when a stone or the like collides with the glass, the glass can be damaged. However, the attachment structure for a vehicle solar cell panel of the first aspect of the present application includes a coupling member including a panel side attachment portion connected to a solar module, a vehicle body side attachment portion connected to a vehicle body structure member, and a connecting portion connecting the panel side attachment portion and the vehicle body side attachment portion and having flexibility. Therefore, even if the glass is damaged, the attachment structure for a vehicle solar cell panel of the first aspect of the present application can reduce the possibility that the solar module flies toward the surroundings of the vehicle body.

[0009] Further, the vehicle body structure member is sometimes a movable member such as a hood. In this case, when the vehicle body structure member contacts other portions of the vehicle body while moving relative to the other portions, an inertial force acts on the solar cell panel, and the solar module tries to move to the vehicle body structure member side. However, the connecting portion of the coupling member has flexibility, and thus the possibility that a large reaction force is generated by the vehicle body structure member from the moving force of the solar module via the coupling member is small. Therefore, the possibility that such a reaction force is transmitted to the solar module via the coupling member is small. Thus, the possibility that the connecting portion between the solar module and the panel side attachment portion is damaged is small.

[0010] As the attachment structure for a vehicle solar cell panel according to the second aspect of the present application, in the first aspect of the present application, the vehicle body side attachment portion can be a clip including a first engaging portion configured to pass through an attachment hole provided in the vehicle body structure member from one surface side to the other surface side of the vehicle body structure member having a plate shape while being elastically deformed, the first engaging portion being in contact with the other surface after passing through the attachment hole, and a second engaging portion being in contact with the one surface after the first engaging portion passes through the attachment hole, the clip being fixed to the glass.

[0011] In the attachment structure for a vehicle solar cell panel of the second aspect of the present application, when the vehicle body side attachment portion as a clip is attached to the attachment hole provided in the vehicle body structure member having a plate shape, the solar cell panel is positioned inside the vehicle body structure member.

[0012] As the attachment structure for a vehicle solar cell panel according to the third aspect of the present application, in the first aspect of the present application, the panel side attachment portion can face one surface of the vehicle body structure member having a plate shape, and can be fixed to the solar module. The connecting portion can pass through a through hole provided in the vehicle body structure member, so as to be movable relative to the through hole. The vehicle body side attachment portion can face the other surface from the other surface side of the vehicle body structure member, and can have a diameter larger than the through hole.

[0013] In the attachment structure for a vehicle solar panel of the third aspect of the present application, when a force in a direction approaching the vehicle body structural member acts on the solar panel, the connecting portion moves inside the through-hole provided in the vehicle body structural member relative to the vehicle body structural member, thereby absorbing the force. Therefore, the force is less likely to act on the vehicle body structural member. Thus, the vehicle body structural member generates a large reaction force and the reaction force is less likely to be transmitted to the solar module via the coupling member. Further, when a force in a direction separating from the vehicle body structural member acts on the solar panel, the vehicle body side attachment portion having a diameter larger than the through-hole cannot move to one surface side of the vehicle body structural member through the through-hole. Therefore, in this case, the solar module is less likely to fly away.

[0014] As the attachment structure for a vehicle solar panel according to the fourth aspect of the present application, in the first aspect of the present application, the panel side attachment portion can be bonded to the solar module, and a portion of the connecting portion can be a low rigidity portion having a rigidity lower than other portions of the connecting portion.

[0015] In the attachment structure for a vehicle solar panel of the fourth aspect of the present application, when a force in a direction separating from the vehicle body structural member acts on the solar panel, a low rigidity portion as a portion of the connecting portion deforms to absorb the force. Therefore, in this case, the panel side attachment portion is less likely to separate from the solar module due to the force. Thus, the solar module is less likely to fly away.

[0016] As the attachment structure for a vehicle solar panel according to the fifth aspect of the present application, in the first aspect of the present application, one surface of the panel side attachment portion having flexibility can be a first surface bonded to the solar module in a thickness direction, and a second surface as another surface of the panel side attachment portion in the thickness direction can include at least one recessed portion.

[0017] In the attachment structure for a vehicle solar panel of the fifth aspect of the present application, when a force in a direction separating from the vehicle body structural member acts on the solar panel, the panel side attachment portion including a recessed portion and having flexibility deforms to absorb the force. Therefore, in this case, the panel side attachment portion is less likely to separate from the solar module due to the force. Thus, the solar module is less likely to fly away.

[0018] As the attachment structure for a vehicle solar cell panel according to the sixth aspect of the present application, in the first aspect of the present application, the facing portion of the support member fixed to the solar module can move relative to the through hole to absorb the force when the force in the direction separating from the vehicle body structure member acts on the solar cell panel. Therefore, in this case, the possibility that the panel side attachment portion separates from the solar module due to the force is small. Further, the diameter of the panel side attachment portion is larger than the diameter of the through hole provided in the facing portion, so the solar module is prevented from flying away by the panel side attachment portion and the facing portion.

[0019] The connecting portion can pass through the through hole so as to be movable relative to the through hole.

[0020] In the attachment structure for a vehicle solar cell panel according to the sixth aspect of the present application, when a force in a direction separating from the vehicle body structure member acts on the solar cell panel, the facing portion (through hole) of the support member fixed to the solar module moves relative to the connecting portion to absorb the force. Therefore, in this case, the possibility that the panel side attachment portion separates from the solar module due to the force is small. Further, the diameter of the panel side attachment portion is larger than the diameter of the through hole provided in the facing portion, so the solar module is prevented from flying away by the panel side attachment portion and the facing portion.

[0021] In the attachment structure for a vehicle solar cell panel according to the seventh aspect of the present application, in the first aspect of the present application, the panel side attachment portion can include a temporary holding portion configured to temporarily hold a portion of the connecting portion.

[0022] In the attachment structure for a vehicle solar cell panel according to the seventh aspect of the present application, when work of attaching the solar cell panel to the vehicle body structure member is performed in a state in which the panel side attachment portion is connected to the solar module, the possibility that the connecting portion hinders the work can be reduced.

[0023] The attachment structure for a vehicle solar cell panel according to the present application has an excellent effect that, when the solar cell panel moves to the vehicle body structure member side, the possibility that the solar module provided in the solar cell panel in the vehicle flies away can be reduced, and the solar cell panel is not easily subjected to the reaction force from the vehicle body structure member.

[0040] The following is for reference Figures 1 to 7Embodiments of an attachment structure for a vehicle solar cell panel according to the present application are described. Note that arrows FR indicated appropriately in the entire drawing indicate a front side of a vehicle, i.e., a front side in a vehicle front-rear direction, arrows LH indicate a left side of the vehicle, i.e., a left side in a vehicle left-right direction, and arrows UP indicate an upper side of the vehicle, i.e., an upper side in a vehicle vertical direction. In the following description, the front-rear direction, the left-right direction, and the vertical direction indicate the vehicle front-rear direction, the vehicle left-right direction, and the vehicle vertical direction, respectively.

[0041] As shown in Figure 1 and Figure 2 , in a front portion of a vehicle body 12 of a vehicle 10, a hood (engine hood) 14 (a vehicle body structure member) capable of opening and closing an upper portion of an engine compartment is provided. A rear end portion of the hood 14 is connected to the vehicle body 12 so as to be rotatable about a rotation axis extending in the left-right direction.

[0042] As shown in Figure 2 and Figure 3 , the hood 14 includes a main body 16 made of metal. The main body 16 includes a hood outer panel (vehicle body structure member) 18 and a hood inner panel (vehicle body structure member) 27, each of which is made of metal and has a substantially rectangular planar shape.

[0043] As shown in Figure 2 and Figure 3 , in a portion of an upper surface of the hood outer panel 18 located on an inner peripheral side of an outer peripheral edge portion, a recessed portion 19 recessed toward the hood inner panel 27 side and having a substantially rectangular shape in a plan view is formed. That is, the hood outer panel 18 includes a bottom surface structure portion 21 located one level below an outer surface structure portion 20 that structures an outer surface of the hood 14. The bottom surface structure portion 21 structures a bottom surface of the recessed portion 19 and has a substantially rectangular shape in a plan view. As shown in Figure 2 , a support portion 22 is provided at a corner portion where a left side edge portion and a front edge portion of the bottom surface structure portion 21 intersect each other. Further, a through-hole 23 having a substantially rectangular shape in a plan view is formed in the bottom surface structure portion 21. Further, as shown in Figure 6 , a second attachment hole (attachment hole) (through-hole) 24 that is a circular through-hole is formed in the support portion 22.

[0044] As shown in Figure 2 and Figure 3 , in a portion of the hood inner panel 27 located on an inner peripheral side of an outer peripheral edge portion, a through-hole 28 having a substantially rectangular shape in a plan view is formed. Further, as shown in Figure 3 , a first attachment hole 29 that is a circular through-hole is formed in a left side portion of the hood inner panel 27.

[0045] A solar panel 30, having a shape slightly smaller than the recess 19 in plan view and being approximately rectangular, is disposed in the recess 19 of the main body 16. For example... Figure 4 As shown, the solar panel 30 in this embodiment and the various modified examples described later includes a glass 31 made of tempered glass that serves as a generally rectangular plate member constituting the outer surface (upper surface) of the solar panel 30; a solar cell array 32 fixed to the lower surface of the glass 31 and having a generally rectangular shape in plan view; a back plate 33 fixed to the lower surface of the solar cell array 32; a gasket 34 fixed to the outer periphery of the glass 31 as a frame member; and a semi-transparent sealing member 35. Figure 3 (Not shown in the image). Please note that the solar cell assembly 32, backsheet 33, and sealing member 35 are components of the solar module 30S. Figure 4 As shown, the solar cell pack 32 of this embodiment and the various modified examples described later includes a plurality of solar cells 32S, each of which is completely covered by a sealing member 35. In other words, a large number of solar cells 32S, glass 31, and backplate 33 are integrated by the sealing member 35. It is well known that each of the solar cells 32S performs a power generation operation using sunlight. The overall shape of the solar cell pack 32 in plan view is smaller than that of the glass 31, and the shape of the backplate 33 in plan view is approximately equal to the overall shape of the solar cell pack 32 in plan view. The overall shape of the solar cell pack 32 in plan view and the shape of the backplate 33 in plan view are approximately equal to the through holes 23, 28. Note that the glass 31 can be laminated glass, consisting of a pair of glass plates stacked via an interlayer. Examples of organic resins used to construct the interlayer include ethylene-vinyl acetate copolymer (EVA) and polyvinyl butyral (PVB).

[0046] like Figures 2 to 5 As shown, near the left edge of the lower surface of the backplate 33 of the solar panel 30, a first connecting member (connecting member) 40, which is an integrally molded product made of resin, is fixed as part of the solar panel 30.

[0047] like Figure 3 and Figure 5As shown, the first connecting member 40 includes a panel-side attachment portion 41, a connecting portion 43, and a vehicle body-side attachment portion 45. The first connecting member 40 is flexible. The panel-side attachment portion 41 is a plate-like portion having a generally rectangular planar shape, and the upper surface of the panel-side attachment portion 41 is fixed to the vicinity of the left left edge of the lower surface of the back panel 33 via adhesive 49. The first end of the strip-shaped connecting portion 43 is fixed to the panel-side attachment portion 41. The second end of the connecting portion 43 is fixed to the vehicle body-side attachment portion 45. The vehicle body-side attachment portion 45 includes a main body portion 46 having a tapered shape with its top cut by a plane, and a cylindrical portion 47 connected to a surface of the main body portion 46 and having a diameter smaller than the diameter of the main body portion 46. The end of the cylindrical portion 47 on the side opposite to the main body portion 46 is fixed to the connecting portion 43. The outer diameter of the cylindrical portion 47 is smaller than the diameter of the first attachment hole 29, and the outer diameter of the end of the main body portion 46 on the cylindrical portion 47 side is larger than the diameter of the first attachment hole 29.

[0048] like Figure 2 , Figure 6 and Figure 7 As shown, a portion of the second connecting member (connecting member) 50 is fixed to the lower surface of the back plate 33 of the solar panel 30 near the corner where the left edge and the front edge intersect.

[0049] like Figure 6 and Figure 7 As shown, the second connecting member 50 includes a body-side attachment portion 51 and a main body portion 55, both made of resin. The body-side attachment portion 51 is a member (clamp) with a tapered shape whose top is cut with a plane. A first annular groove 52 and a second annular groove 53, both having annular shapes, are formed on the outer peripheral surface of the body-side attachment portion 51. The diameter of the second annular groove 53 is larger than that of the first annular groove 52. The upper surface of the body-side attachment portion 51 is fixed to the lower surface of the glass 31 by an adhesive. The flexible main body portion 55 integrally includes a panel-side attachment portion 56 and a connecting portion 57. The panel-side attachment portion 56 is a plate-like portion having a generally rectangular planar shape, and the upper surface of the panel-side attachment portion 56 is fixed to the lower surface of the back panel 33 by an adhesive 58 near the aforementioned corner portion. The first end of the strip-shaped connecting portion 57 is fixed to the middle portion of the panel-side attachment portion 56. An attachment hole 57A, which serves as a circular through hole, is formed at the second end of the connecting portion 57. The diameter of the attachment hole 57A is approximately equal to the second annular groove 53 of the vehicle side attachment portion 51, and smaller than the outer diameter of the maximum diameter portion (upper end) of the vehicle side attachment portion 51. The second annular groove 53 of the vehicle side attachment portion 51 is fitted to the outer periphery of the attachment hole 57A of the connecting portion 57. In this way, the vehicle side attachment portion 51 and the main body portion 55 are integrated.

[0050] As described above, the solar panel 30, which is integrated with the first connecting member 40 and the second connecting member 50, is fixed to the engine hood 14 by, for example, the following method.

[0051] First, the adhesive 59 is applied to the outer peripheral portion of the lower surface of the glass 31. Subsequently, when the outer peripheral portion of the solar battery panel 30 is positioned directly above the outer peripheral portion of the recessed portion 19, the solar battery panel 30 is caused to approach the recessed portion 19 from the upper side of the hood 14. As shown in Figure 6 , when the solar battery panel 30 is further moved to the bottom surface side of the recessed portion 19, the first engaging portion 51A (small diameter end portion) that is the lower end portion of the vehicle body side attachment portion 51 passes through the second attachment hole 24 of the support portion 22 downward while being elastically deformed, and thus the first annular groove 52 of the vehicle body side attachment portion 51 is fitted to the outer peripheral edge portion of the second attachment hole 24 of the support portion 22 (see Figure 6 ). This allows the first engaging portion 51A to be in contact with the lower surface of the support portion 22, and also allows the second engaging portion 51B that is a portion between the first annular groove 52 and the second annular groove 53 of the vehicle body side attachment portion 51 to be in contact with the upper surface of the support portion 22. That is, with the vehicle body side attachment portion 51, the solar battery panel 30 is positioned in the recessed portion 19 (bottom surface structure portion 21). Further, the adhesive 59 is in contact with the upper surface of the bottom surface structure portion 21 of the hood outer panel 18, and thus the gasket 34 is in close contact with the outer peripheral edge portion of the recessed portion 19. In this way, the solar battery panel 30 is fixed to the main body 16 (recessed portion 19).

[0052] Further, as shown in Figure 3 , the vehicle body side attachment portion 45 of the first coupling member 40 is caused to approach the hood inner panel 27 from below, and the upper end portion (small diameter end portion) of the main body portion 46 is pushed into the first attachment hole 29 of the hood inner panel 27. In this way, the main body portion 46 passes through the first attachment hole 29 upward while being elastically deformed, and the cylindrical portion 47 is positioned inside the first attachment hole 29.

[0053] Effects

[0054] Next, the effects of the present embodiment will be described.

[0055] The solar battery panel 30 of the present embodiment includes the glass 31 exposed to the outside of the vehicle 10, the solar battery storage group 32 provided on the vehicle inner side surface of the glass 31, the back sheet 33 provided on the vehicle inner side surface of the solar battery storage group 32, and the sealing member 35. Therefore, during travel of the vehicle 10, when a stone on the road surface kicked up by a wheel collides with the glass 31, the glass 31 can be damaged.

[0056] However, the entire solar battery pack 32 is attached to the back panel 33 via the sealing member 35. Therefore, even when the glass 31 is broken, the role of the sealing member 35 reduces the possibility that the solar battery pack 32, the back panel 33, and the sealing member 35 are divided into multiple parts. In addition, the first coupling member 40 includes a panel-side attachment portion 41 fixed to the back panel 33, a vehicle body-side attachment portion 45 connected to the hood 14 (the hood inner panel 27), and a connecting portion 43 connecting the panel-side attachment portion 41 and the vehicle body-side attachment portion 45 and having flexibility. In addition, the second coupling member 50 includes a panel-side attachment portion 56 fixed to the back panel 33, a vehicle body-side attachment portion 51 connected to the hood 14 (the hood outer panel 18), and a connecting portion 57 connecting the vehicle body-side attachment portion 51 and the panel-side attachment portion 56 and having flexibility. Therefore, even if the glass 31 is damaged, with the first coupling member 40 and the second coupling member 50, the solar module 30S is prevented from being significantly moved from the hood 14 to the outside of the vehicle. Therefore, the possibility that the solar module 30S flies around the vehicle body 12 is small.

[0057] In addition, the hood 14 on which the solar cell panel 30 is provided is movable with respect to the vehicle body 12. That is, the hood 14 can open and close the vehicle body 12 between a closed position that closes the engine compartment and an open position that exposes the engine compartment. When the hood 14 in the open position is moved to the closed position, the hood 14 comes into contact with a portion of the vehicle body 12, and thus an inertial force is generated in the solar cell panel 30 to move the solar cell panel 30 to the hood inner panel 27 side. However, the connecting portion 43 of the first coupling member 40 and the connecting portion 57 of the second coupling member 50 have flexibility, and thus the possibility that the moving force of the solar cell panel 30 is transmitted to the hood outer panel 18 (the bottom surface structure portion 21) and the hood inner panel 27 via the first coupling member 40 and the second coupling member 50 to cause the hood outer panel 18 and the hood inner panel 27 to generate a reaction force is small. Therefore, the possibility that the connecting portion between the solar module 30S and the panel-side attachment portion 41 is damaged, or the possibility that the solar module 30S is damaged due to such a reaction force is small.

[0058] The above has described the attachment structure for a vehicle solar cell panel according to the embodiment, but the design of the present application can be appropriately changed without departing from the gist of the present application.

[0059] For example, the present application can be applied to Figure 8 and Figure 9One scheme of the illustrated first modification example is implemented. In the attachment structure for a vehicle solar cell panel of the first modification example, a support portion 22A is formed in the bottom surface structure portion 21 of the hood outer panel 18 of the hood 14. The support portion 22A is located one level below the other portion of the bottom surface structure portion 21. Further, a first attachment hole (through hole) 29 is formed in the support portion 22A.

[0060] The first coupling member (coupling member) 60 of the first modification example includes a panel side attachment portion 61, a connecting portion 62, and a vehicle body side attachment portion 63. The first coupling member 60 has flexibility. The panel side attachment portion 61 is a plate-shaped portion having a substantially rectangular planar shape, and an upper surface of the panel side attachment portion 61 is fixed to the left side edge portion of the lower surface of the back panel 33 via the adhesive 58. A first end of the connecting portion 62 having a cylindrical shape is fixed to an end portion of the panel side attachment portion 61 on the side opposite to the back panel 33. The vehicle body side attachment portion 63 having a conical shape whose top portion is cut flat is fixed to a second end of the connecting portion 62. An outer diameter of the connecting portion 62 is smaller than a diameter of the first attachment hole 29, and an outer diameter of an end portion of the vehicle body side attachment portion 63 on the connecting portion 62 side is larger than the diameter of the first attachment hole 29. The connecting portion 62 is located inside the first attachment hole 29, and the vehicle body side attachment portion 63 is located below the support portion 22A.

[0061] For example, when an inertial force acts on the solar cell panel 30 due to movement of the hood 14 from the open position to the closed position, the inertial force moves the solar cell panel 30 to the bottom surface structure portion 21 (support portion 22A) side. In this case, when the connecting portion 62 moves downward with respect to the first attachment hole 29 (support portion 22A), the moving force of the solar cell panel 30 to the bottom surface structure portion 21 side is absorbed. Therefore, due to the inertial force, the first coupling member 60 collides with the bottom surface structure portion 21 (support portion 22A) violently, which causes the bottom surface structure portion 21 to generate a large reaction force due to the collision, and the reaction force is less likely to be transmitted to the solar module 30S via the first coupling member 60. Therefore, the connecting portion between the solar module 30S and the panel side attachment portion 61 is less likely to be damaged, or the solar module 30S is less likely to be damaged due to such a reaction force.

[0062] Further, in some cases, for example, due to movement of the hood 14 from the open position to the closed position or collision of a stone or the like against the solar cell panel 30, the glass 31 can be damaged, and the solar cell panel 30 is lifted upward with respect to the bottom surface structure portion 21 by wind W (wind pressure) passing through the gap between the glass 31 (gasket 34) and the hood outer panel 18 (recess 19) (see Figure 9). In this case, the upper end portion (large diameter portion) of the body side attachment portion 63 contacts the lower surface of the support portion 22A without passing upward through the first attachment hole 29. Therefore, the body side attachment portion 63 prevents the solar cell panel 30 from being significantly moved to the outside of the vehicle from the hood 14.

[0063] Furthermore, the present application can be implemented in Figure 10 In one aspect of the second modification example shown in FIG. 8, the first coupling member (coupling member) 65 having flexibility includes the panel side attachment portion 41, the connecting portion 66 having a first end connected to the middle portion of the panel side attachment portion 41, and the body side attachment portion 45 (not shown) connected to a second end of the connecting portion 66. The cylindrical portion 47 of the body side attachment portion 45 passes through the first attachment hole 29 of the inner panel 27 of the hood, and the main body portion 46 is located above the inner panel 27 of the hood.

[0064] The connecting portion 66 of the first coupling member 65 is configured by a thin portion (low rigidity portion) 67 thinner than other portions of the connecting portion 66 near the end portion on the panel side attachment portion 41 side. Therefore, the thin portion 67 has a lower rigidity and is easily bent compared to other portions of the connecting portion 66.

[0065] For example, as described above, when the solar cell panel 30 is lifted upward with respect to the bottom surface configuration portion 21 by wind passing through the gap between the glass 31 (gasket 34) and the outer panel 18 (recessed portion 19), the thin portion 67 of the connecting portion 66 is significantly bent to prevent a force that separates the back sheet 33 and the panel side attachment portion 41 from each other from being generated between the back sheet 33 and the panel side attachment portion 41. Therefore, in this case, the possibility that the back sheet 33 is separated from the panel side attachment portion 41 to cause the solar module 30S to fly around the body 12 is small.

[0066] Furthermore, the present application can be implemented in Figure 11 In one aspect of the third modification example shown in FIG. 9, the first coupling member (coupling member) 70 having flexibility includes the panel side attachment portion 71, the connecting portion 43 having a first end connected to the middle portion of the panel side attachment portion 71, and the body side attachment portion 45 (not shown) connected to a second end of the connecting portion 43. The cylindrical portion 47 of the body side attachment portion 45 passes through the first attachment hole 29 of the inner panel 27 of the hood, and the main body portion 46 is located above the inner panel 27 of the hood.

[0067] The front portion shape (along the arrow A) of the panel side attachment portion 71 is a shape that is gradually reduced toward the front end portion. Figure 11The shape viewed in the up-down direction is substantially rectangular. One surface in the thickness direction of the flexible panel-side attachment portion 71 is a first surface 72 fixed to the flat surface of the back plate 33 via the adhesive 58. The other surface in the thickness direction of the panel-side attachment portion 71 is a curved second surface 73. The thickness of the panel-side attachment portion 71 gradually decreases from the inner peripheral side toward the outer peripheral side. Further, in the second surface 73, a plurality of concentric annular grooves (recesses) 74 are formed. The cross-sectional shape of each annular groove 74 in a direction orthogonal to the extending direction of the annular groove 74 is, for example, U-shaped or V-shaped. Thus, compared to a case where the annular grooves 74 are not formed, the panel-side attachment portion 71 is easily deformed.

[0068] For example, as described above, when the solar battery panel 30 is lifted upward with respect to the bottom surface structure portion 21 by wind passing through the gap between the glass 31 (gasket 34) and the hood outer panel 18 (recess 19), the panel-side attachment portion 71 having the annular grooves 74 formed in the second surface 73 deforms so as to follow the movement of the solar battery pack 32. This prevents a force that separates the back plate 33 and the panel-side attachment portion 71 from each other from being generated between the back plate 33 and the panel-side attachment portion 71. Thus, in this case, the possibility that the back plate 33 is separated from the panel-side attachment portion 71 to cause the solar module 30S to fly around the vehicle body 12 is small.

[0069] Further, the present application can be implemented in one aspect of a fourth modification example shown in Figure 12 and Figure 13 In the attachment structure for a vehicle solar battery panel of the fourth modification example, a support member 75 made of metal and having a U-shaped cross section is fixed to the back plate 33. The lower end portion of the support member 75 is structured by a flat surface facing portion 76 separated downward from the back plate 33. A circular attachment hole (through hole) 77 is provided in the facing portion 76.

[0070] The first coupling member (coupling member) 80 of the fourth modification example includes a panel-side attachment portion 81, a connecting portion 43 having a first end connected to the panel-side attachment portion 81, and a vehicle body-side attachment portion 45. The cylindrical portion 47 of the vehicle body-side attachment portion 45 passes through the first attachment hole 29 of the hood inner panel 27, and the main body portion 46 is located above the hood inner panel 27. The panel-side attachment portion 81 is located in the space between the back plate 33 (adhesive 49) and the facing portion 76, and the end portion of the connecting portion 43 on the panel-side attachment portion 81 side passes through the attachment hole 77 so as to be movable. The outer diameter of the lower end portion (large diameter end portion) of the panel-side attachment portion 81 is larger than the diameter of the attachment hole 77.

[0071] For example, as described above, when the solar panel 30 is lifted upward with respect to the bottom surface structure portion 21 by wind passing through the gap between the glass 31 (the gasket 34) and the hood outer panel 18 (the recess 19), the facing portion 76 (the attachment hole 77) moves in various directions with respect to the connecting portion 43. That is, the facing portion 76 slides in the axial direction of the attachment hole 77 with respect to the connecting portion 43, the facing portion 76 moves in a direction inclined with respect to the axial direction of the attachment hole 77 with respect to the connecting portion 43, or the facing portion 76 rotates with respect to the connecting portion 43 around the axis of the connecting portion 43. This prevents a force that separates the back panel 33 and the support member 75 from each other from being generated between the back panel 33 and the support member 75. Therefore, in this case, the possibility that the back panel 33 is separated from the support member 75 and causes the solar module 30S to fly around the vehicle body 12 is small.

[0072] Furthermore, the present application can be implemented in one aspect of a fifth modified example shown in Figure 14 and Figure 15 In the attachment structure for a vehicle solar panel of the fifth modified example, the first coupling member 85 includes a temporary holding portion 86 having a U-shaped cross-sectional shape and fixed to the panel-side attachment portion 41. The temporary holding portion 86 can be elastically deformed.

[0073] As shown in Figure 14 , in a temporary holding groove 87 of the temporary holding portion 86, an end portion 43A of the connecting portion 43 on the side opposite to the panel-side attachment portion 41 can be inserted, and thus the end portion 43A can be temporarily held by the temporary holding portion 86. Therefore, in a state where the end portion 43A is temporarily held by the temporary holding portion 86, as described above, in a case where the adhesive 59 is in contact with the upper surface of the bottom surface structure portion 21 of the hood outer panel 18, the solar panel 30 can be attached to the main body 16 (the recess 19) such that the gasket 34 is in close contact with the outer peripheral portion of the recess 19.

[0074] After that, the end portion 43A is detached from the temporary holding portion 86, and as shown in Figure 15 , the body-side attachment portion 45 of the first coupling member 85 is brought close to the first attachment hole 29 from the lower side of the hood inner panel 27, and the upper end portion (small diameter end portion) of the body portion 46 is pushed into the first attachment hole 29. Therefore, the body portion 46 can be positioned above the hood inner panel 27, and the cylindrical portion 47 can be positioned inside the first attachment hole 29.

[0075] As described above, the work of attaching the solar cell panel 30 to the main body 16 (the recessed portion 19) can be performed in a state in which the end portion 43A is temporarily held by the temporary holding portion 86, and thus the solar cell panel 30 can be attached to the main body 16 while preventing the connecting portion 43 from being sandwiched between the solar cell panel 30 and the main body 16 (the recessed portion 19). Therefore, the operator can smoothly perform the work of attaching the solar cell panel 30 to the main body 16.

[0076] The attachment structure for a vehicle solar cell panel of the present embodiment and all modified examples can include only the first coupling member.

[0077] The shape of the recess formed in the second surface 73 of the panel-side attachment portion 71 can be different from the shape of the annular groove 74.

[0078] The attachment structure for a vehicle solar cell panel of the present embodiment can be applied to a vehicle body structure member other than the hood 14. For example, the attachment structure for a vehicle solar cell panel can be applied to a roof portion (a vehicle body structure member) 12R of the vehicle body 12 (see FIG. 1). Note that when the attachment structure for a vehicle solar cell panel is applied to the roof portion 12R, the solar cell panel 30 cannot be moved relative to the vehicle body 12. Figure 1 ) of the vehicle body 12. Note that when the attachment structure for a vehicle solar cell panel is applied to the roof portion 12R, the solar cell panel 30 cannot be moved relative to the vehicle body 12.

[0079] The connecting portion of each of the first coupling member and the second coupling member can be a wire made of metal that couples the panel-side attachment portion and the vehicle body-side attachment portion.
