[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to the accompanying drawings, in which the same or corresponding components are designated by the same reference numerals.
[0010] Fig. 1 is a perspective view showing a schematic configuration of a fixing structure for a solar power generation panel according to an embodiment of the present disclosure, Fig. 2 is a perspective view of a roof rail, and Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1.
[0011] As shown in FIGS. 1 to 3, the fixing structure for a solar power generation panel includes a pair of roof rails 100, a solar power generation panel 200, and a fixing member 300.
[0012] The pair of roof rails 100 are fixed to the roof 12 of the vehicle 10. The pair of roof rails 100 are provided at a distance in the width direction of the vehicle 10. Each roof rail 100 has a holding portion 110 that holds a solar power generation panel 200. The holding portion 110 has a shape that extends continuously in the front-rear direction of the vehicle. However, the holding portion 110 may be composed of a plurality of holding elements provided at intervals in the front-rear direction.
[0013] As shown in FIG. 2, the holding portion 110 in this embodiment is configured as a groove provided on inner surfaces 100S of a pair of roof rails 100 facing each other in the width direction. The groove opens rearward. This opening may be closed by a cap 150 that is detachable from the rear end of the roof rail 100. The depth of the groove (dimension in the width direction) may be set to be constant over the entire area of the groove in the front-rear direction, or may be set to gradually decrease toward the front of the vehicle. The height of the groove may be set to be constant over the entire area of the holding portion 110 in the front-rear direction, or may be set to gradually decrease toward the front of the vehicle.
[0014] The solar panel 200 is formed in a flat plate shape. The solar panel 200 may be formed in a slightly curved shape so as to be convex upward. As shown in FIG. 3, the solar panel 200 has a panel body 210 and a panel edge portion 220.
[0015] The panel body 210 is positioned between a pair of roof rails 100. The panel body 210 has a solar cell 212 and a sealing layer 214. Wiring for the solar cell 212 is led into the vehicle interior through, for example, the shark fin 14 (see FIG. 6).
[0016] The sealing layer 214 seals the solar cell 212. The sealing layer 214 is made of a resin having optical transparency. The sealing layer 214 is made of, for example, ethylene vinyl acetate (EVA), polyolefin, silicone, or ionomer. A cover made of glass or a resin film may be provided on the surface of the sealing layer 214.
[0017] The panel edge 220 extends outward in the width direction from the panel body 210. The panel edge 220 is molded integrally with the sealing layer 214 using the same material as that forming the sealing layer 214. The thickness of the panel edge 220 is substantially the same as or slightly smaller than the height of the holding portion 110. The panel edge 220 is inserted from the rear end of the groove that constitutes the holding portion 110 toward the front.
[0018] The fixing member 300 detachably fixes the solar power generation panel 200 to the pair of roof rails 100. Specifically, the fixing member 300 fixes the panel edge portion 220 of the solar power generation panel 200 to the holding portion 110 of the roof rail 100. In this embodiment, the fixing member 300 is configured with a fastening member (such as a bolt or a rivet).
[0019] As described above, in the solar power generation panel fixing structure 1 of this embodiment, the panel edge portion 220 of the solar power generation panel 200 can be fixed to the holding portion 110 of the roof rail 100 by the fixing member 300, making it possible to easily attach and detach the solar power generation panel 200 to the vehicle.
[0020] Next, a modification of the above embodiment will be described.
[0021] (First Modification) 4, the panel edge portion 220 has an extension portion 222 and an engagement portion 224. The extension portion 222 has a shape extending in the width direction from the panel main body 210. The extension portion 222 is molded integrally with the sealing layer 214 using the same material as that forming the sealing layer 214. The engagement portion 224 has a shape extending from the extension portion 222 in a direction intersecting the width direction (e.g., downward).
[0022] The holding portion 110 has a support portion 112 and a locking portion 114. The support portion 112 supports an extension portion 222. The thickness of the extension portion 222 is substantially the same as or slightly smaller than the height of the support portion 112. The locking portion 114 extends downward from the outer end portion of the support portion 112 in the width direction. The locking portion 114 is provided on the inner side of the engagement portion 224 in the width direction. The locking portion 114 locks the engagement portion 224.
[0023] The fixing member 300 passes through the extending portion 222 and fixes the extending portion 222 to the support portion 112 .
[0024] In this embodiment, the engagement portion 224 engages with the locking portion 114, so that the solar power generation panel 200 is prevented from coming off the roof rail 100.
[0025] (Second Modification) 5, the panel edge portion 220 has an elastic portion 226 and a reinforcing portion 228. The elastic portion 226 is made of an elastic material and is connected to the panel main body 210. The elastic portion 226 is made of, for example, rubber. The elastic portion 226 is welded to an end portion of the panel main body 210 in the width direction.
[0026] The reinforcing portion 228 has a higher rigidity than the elastic portion 226. The reinforcing portion 228 is made of, for example, a metal. The reinforcing portion 228 covers at least the upper and lower surfaces of the elastic portion 226. In the example shown in Fig. 5, the reinforcing portion 228 covers the upper and lower surfaces of the elastic portion 226 and the outer end surface of the elastic portion 226 in the width direction.
[0027] The fixing member 300 fastens the elastic portion 226 and the reinforcing portion 228 to the holding portion 110 in a state in which the fixing member 300 penetrates the elastic portion 226 and the reinforcing portion 228 in the thickness direction (vertical direction) of the elastic portion 226 .
[0028] In this embodiment, the elastic portion 226 absorbs the linear expansion of the panel body 210, thereby suppressing distortion, damage, and the like of the panel body 210. Furthermore, the reinforcing portion 228 is provided, so that the fastening force of the fixing member 300 is effectively ensured. Note that the reinforcing portion 228 may be omitted. However, by providing the reinforcing portion 228, damage and deterioration of the elastic portion 226 due to external input is suppressed compared to a case in which the reinforcing portion 228 is omitted and the panel edge portion 220 is composed of only the elastic portion 226.
[0029] (Third Modification) 6, the solar power generation panel fixing structure 1 further includes a support member 400 that supports the solar power generation panel 200. The support member 400 connects the pair of roof rails 100 to each other. An upper surface of the support member 400 may be adhered to a lower surface of the panel body 210.
[0030] (Fourth Modification) As shown in FIG. 7, the holding portion 110 of the roof rail 100 may be configured with a step portion capable of supporting the panel edge portion 220.
