Description

Frame for panel module and frame structure for panel module

The present invention relates to a frame for a panel-shaped module such as a solar cell module, and a frame structure including the frame.

Panel-like modules such as solar cell modules will be installed outdoors for a long period of time. Therefore, if the rain poured on the surface of the panel-shaped module is not properly drained, the collected rainwater will stain the panel. When the panel-shaped module is a solar cell module, the power generation efficiency may decrease due to accumulated rainwater and dirt resulting therefrom.

Patent Document 1 discloses forming a notch in a frame provided at the edge of a solar cell panel to form a drainage channel for rainwater that communicates from the surface of the solar cell panel to the outside of the frame surrounding the solar cell panel. Will be disclosed.

Embodiments will be described below with reference to the drawings. In the following drawings, the same or similar reference numerals are given to the same or similar parts. However, it should be noted that the drawings are schematic and the ratios of the respective dimensions may differ from the actual ones.

FIG. 1 is a plan view of the panel-shaped module 20. FIG. 2 is a rear view of the panel-shaped module viewed from the side opposite to FIG. The panel-shaped module 20 may be an outdoor module. The panel-shaped module 20 is preferably a solar cell module, for example. When the panel-shaped module 20 is a solar cell module, FIG. 1 corresponds to a plan view seen from the light receiving surface side of the solar cell module.

The panel-shaped module 20 may be installed such that the main surface of the panel is inclined with respect to the horizontal direction. Alternatively, the panel-shaped module 20 may be installed such that the main surface of the panel-shaped module 20 is substantially along the horizontal plane.

The panel-shaped module 20 may include a panel 210, a first frame 220, and a second frame 230. When the panel module 20 is a solar cell module, the panel 210 is composed of a photoelectric conversion element that converts light into electricity. In this case, the front surface of panel 210 is a light receiving surface that receives light, and the back surface of panel 210 is a non-light receiving surface. The panel 210 may have a flat plate shape. In the present embodiment, the panel 210 has a substantially rectangular shape when viewed from the thickness direction of the panel 210.

The first frame 220 and the second frame 230 are provided along the outer edge of the panel 210, respectively. In the present embodiment, the first frame 220 extends along a first direction along the first edge of the panel 210 (hereinafter, also referred to as “lateral direction”). The second frame 230 may extend along a second direction (hereinafter, also referred to as “vertical direction”) along the second edge of the panel 210. Here, the first direction (horizontal direction) and the second direction (vertical direction) may be directions intersecting with each other, and preferably directions orthogonal to each other.

In a specific example, the first frame 220 may have a length of 1230 mm to 1280 mm. Also, the second frame 230 may have a length of 900 mm to 1000 mm.

FIG. 3 is a cross-sectional view taken along the line 3A-3A in FIG. 1, showing a cross-sectional structure of the first frame 220. FIG. 4 is a perspective view of the first frame 220 of the panel module 20. FIG. 5 is a cross-sectional view taken along the line 5A-5A in FIG. 1, showing a cross-sectional structure of the second frame 230. FIG. 6 is a perspective view of the second frame 230 of the panel-shaped module. FIG. 7 is a plan view of the region 7R of FIG. 1 viewed from the direction of arrow 7A.

The first frame 220 may include a first holding portion 221, a first leg portion 222, a first upright portion 223, a first flange 224, and a first panel receiving portion 225. The first flange 224 extends in the lateral direction along the first edge of the panel 210 and covers the upper surface of the first edge of the panel 210.

The first panel receiving portion 225 is configured to be able to receive the outer edge of the panel 210. In addition, the first holding portion 221 is configured to support the first edge of the panel 210 from below, and faces the first flange 224. In this case, the first holding portion 221 configures the first panel receiving portion 225 that receives the panel 210 together with the first flange 224. As a specific example, the wall portion forming the first panel receiving portion 225 has a substantially horizontal “U” shape in a cross section orthogonal to the extending direction (horizontal direction) of the first frame 220. ..

The inside of the first panel receiving portion 225 may be filled with a first sealing material 229. Thereby, the first panel receiving portion 225 can hold the panel 210 in a state of receiving the end portion of the panel 210. The first sealing material 229 may be provided on the entire first panel receiving portion 225 in the lateral direction, or may be provided only on a partial region of the first panel receiving portion 225 in the lateral direction.

The first leg 222 is located on the opposite side of the first flange 224 with respect to the first upright portion 223 and a first contact portion 223a described later in the direction orthogonal to the panel 210. The first leg 222 extends in a direction substantially parallel to the panel 210. Specifically, the first leg 222 may extend at least from the first upright portion 223 in a direction opposite to the opening direction of the first panel receiving portion 225.

The first standing portion 223 extends on the back surface of the panel 210 in a direction intersecting with the panel 210. Specifically, the first upright portion 223 extends from the first leg portion 222 to the first holding portion 221. More specifically, the first upright portion 223 connects the end of the first holding portion 221 on the panel 210 side and the end of the first leg 222 on the panel 210 side. As a result, the first frame 220 has a substantially S-shape when viewed from the extending direction of the first frame 220 (see FIG. 3).

The first leg portion 222, the first upright portion 223, the first holding portion 221, and the first flange 224 may each extend in the extending direction of the first frame 220. The first leg portion 222, the first standing portion 223, the first holding portion 221, and the first flange 224 may be integrally formed.

The first standing portion 223 abuts the side surface of the second frame 230 at both ends of the first frame 220 in the lateral direction (see also FIG. 7). Therefore, the side surface of the first upright portion 223 constitutes a first contact portion 223 a that contacts the second frame 230.

In the present embodiment, the first leg portion 222 extends at least from the first upright portion 223 only in the direction opposite to the opening direction of the first panel receiving portion 225. This prevents the first leg 222 from interfering with the second frame 230 when the second frame 230 is in contact with the first contact portion 223a of the first frame 220.

Preferably, each of the first flange 224 and the first holding portion 221 has the same shape in a cross section orthogonal to the lateral direction at any position from one end to the other end in the lateral direction. More preferably, each of the first flange 224, the first holding portion 221, and the first leg portion 222 has the same shape in a cross section orthogonal to the horizontal direction at any position from one end to the other end in the horizontal direction. This means that the first flange 224, the first holding portion 221, and the first leg 222 have the same length in the lateral direction. More preferably, the first frame 220 has the same cross-sectional shape at any position in the lateral direction from one end to the other end, except for the hole formed in the first upright portion 223. The first frame 220 having such a shape can be easily manufactured by, for example, extrusion molding.

The length L21 of the first flange 224 in the vertical direction may be, for example, 10 mm to 16 mm (see FIG. 3). The distance L22 from the lower end of the first leg 222 to the upper end of the first flange 224 may be 32 mm to 38 mm. The length L23 of the first leg 222 in the vertical direction may be, for example, 10.5 mm to 16.5 mm. The distance L25 between the first holding portion 221 and the first flange 224 may be, for example, about 3 to 9 mm.

The first contact portion 223a is located outside the tip of the first flange 224 in the vertical direction when viewed from the direction orthogonal to the panel 210. As a result, the first flange 224 does not come into contact with the second frame 230, and the space between the tip end of the first flange 224 and the first rising portion 223 (first contact portion 223a) is L24 in the vertical direction. Exists (see FIG. 7). The distance L24 may be, for example, about 0.1 mm to 2.0 mm.

The first upright portion 223 of the first frame 220 may have a plurality of

holes

226 and 227 through which a fastening member such as a bolt can be inserted. In the present embodiment, two first hole portions 226 are arranged in the height direction. Instead of this, only one first hole 226 may be provided in the height direction.

The center of the first hole portion 226 may be provided at a position, for example, 7.5 mm to 13.5 mm from the end of the first frame 220 in the lateral direction. The centers of the first holes 226 may be provided at a height of, for example, 6 mm to 12 mm and 16 mm to 21 mm from the lower end of the first frame 220, respectively.

The first hole 226 is provided to connect the second frame 230 to the first frame 220. On the other hand, the second hole 227 is provided to connect the reinforcing member 240, which will be described later, to the first frame 220. The second hole portion 227 of the first frame 220 is preferably provided at a position where the stress applied to the first frame 220 by the load is reduced. This can prevent the load resistance of the first frame 220 from decreasing.

The second frame 230 may include a second holding portion 231, a second leg portion 232, a second upright portion 233, a second flange 234, and a second panel receiving portion 235. The second flange 234 extends in the vertical direction along the second edge of the panel 210 and covers the upper surface of the second edge of the panel 210.

The second panel receiving portion 235 is configured to be able to receive the outer edge of the panel 210. In addition, the second holding portion 231 is configured to support the second edge of the panel 210 from below, and faces the second flange 234. In this case, the second holding portion 231 configures the second panel receiving portion 235 that receives the panel 210 together with the first flange 234. As a specific example, the wall portion that constitutes the second panel receiving portion 235 has a substantially horizontal “U” shape in a cross section orthogonal to the extending direction (longitudinal direction) of the second frame 230.

The inside of the second panel receiving portion 235 may be filled with the second sealing material 239. Thereby, the second panel receiving portion 235 can hold the panel 210 in a state of receiving the end portion of the panel 210. The second sealing material 239 may be provided on the entire second panel receiving portion 235 in the vertical direction, or may be provided only on a partial region of the second panel receiving portion 235 in the vertical direction.

The second leg 232 is located on the side opposite to the second flange 234 with respect to the second upright portion 233 in the direction orthogonal to the panel 210. The second leg portion 232 extends in a direction substantially parallel to the panel 210. Specifically, the second leg portion 232 may extend at least from the second upright portion 233 in a direction opposite to the opening direction of the second panel receiving portion 235. In the present embodiment, the second leg portion 232 extends from the second upright portion 233 in both the opening direction of the second panel receiving portion 235 and the direction opposite to the opening direction of the second panel receiving portion 235. (See Figure 5).

The second standing portion 233 extends on the back surface of the panel 210 in a direction intersecting with the panel 210. Specifically, the second upright portion 233 extends from the second leg portion 232 to the second holding portion 231. More specifically, the second holding portion 231, the second upright portion 233, and the second leg portion 232 form a substantially I-shaped shape in a sectional view (see FIG. 5 ).

The second leg portion 232, the second upright portion 233, the second holding portion 231, and the second flange 234 may each extend in the extending direction of the second frame 230. The second leg portion 232, the second rising portion 233, the second holding portion 231, and the second flange 234 may be integrally formed.

The side surfaces of the second frame 230 in the vertical direction form second contact portions 238 that contact the first contact portions 223a of the first frame 220 at both ends of the first frame 220 (see FIG. 7). More specifically, the side surface of the second rising portion 233 of the second frame 230 may form the second contact portion 238. In this case, the second flange 234 of the second frame 230 may end at the same position as the second contact portion 238 in the vertical direction.

Preferably, each of the second flange 234 and the second holding portion 231 has the same shape in a cross section orthogonal to the vertical direction at any position from one end to the other end in the vertical direction. More preferably, each of the second flange 234, the second holding portion 231, and the second leg portion 232 has the same shape in a cross section orthogonal to the vertical direction at any position in the vertical direction from one end to the other end. More preferably, each of the second flange 234, the second holding portion 231, the second leg portion 232, and the second rising portion 233 has a cross section orthogonal to the vertical direction at any position from one end to the other end in the vertical direction. And have the same shape. This means that the second flange 234, the second holding portion 231, the second rising portion 233, and the second leg portion 232 have the same length in the vertical direction. Most preferably, the second frame 230 has the same cross-sectional shape at any position in the extending direction of the second frame 230. The second frame 230 having such a shape can be easily manufactured by, for example, extrusion molding.

The length L41 of the second flange 234 in the lateral direction may be, for example, 10.5 mm to 16.5 mm (see FIG. 5). The distance L42 from the lower end of the second leg 232 to the upper end of the second flange 234 may be, for example, 32 mm to 38 mm. The length L43 of the second leg portion 232 in the lateral direction may be, for example, 10.0 mm to 16.0 mm. The distance L45 between the second holding portion 231 and the second flange 234 may be, for example, about 3 to 9 mm.

The second upright portion 233 has a third hole portion 236 through which a fastening member such as a bolt can be inserted. The third hole portion 236 is surrounded by a C-shaped structure 237 in a sectional view. In the present embodiment, the C-shaped structure 237 is provided on the second upright portion 233 and extends along the extending direction of the second frame 230. Therefore, the C-shaped structure 237 has a substantially cylindrical shape.

The third hole 236 of the second frame 230 is aligned with the first hole 226 of the first frame 220. A fastening member 250 such as a bolt passes through both the first hole 226 of the first frame 220 and the third hole 236 of the second frame 230 (see FIG. 7). As a result, the first frame 220 and the second frame 230 are fastened to each other with the first contact portion 223a of the first frame 220 and the second contact portion 238 of the second frame 230 contacting each other. ..

The center of the third hole 236 of the second frame 230 may be provided at a position, for example, 7.5 mm to 13.5 mm from the outer end of the second frame 230 in the lateral direction. Further, the centers of the third holes 236 of the second frame 230 may be provided at a height of, for example, 6 mm to 12 mm and 16 mm to 21 mm from the lower end of the second frame 230, respectively.

As shown in FIG. 7, in a state where the first frame 220 and the second frame 230 are fastened to each other, the second contact portion 238, which is the side surface of the second frame 230, is not connected to the first contact portion of the first frame 220. It abuts the portion 223a. Here, as described above, the first flange 224 of the first frame 220 does not abut the second frame 230, and the first abutting portion 223a is vertical in the vertical direction when viewed from the direction orthogonal to the panel 210. It is located outside the tip of the first flange 224. As a result, a gap SP is formed between the first frame 220 and the second frame 230 on the upper surface of the panel 210 (FIG. 7). The gap SP has a role of a drainage path for letting water poured on the surface of the panel 210, for example, rainwater, escape to the outside of the panel 210.

In this embodiment, the drainage gap SP is formed only by fastening the first frame 220 and the second frame 230 to each other. In this case, it is not necessary to introduce a step of forming a hole, a notch, or a groove for the purpose of forming a drainage channel in the first frame 220 or the second frame 230. Therefore, the drainage channel can be easily formed without increasing the manufacturing steps of the first frame 220 and the second frame 230.

In the present embodiment, a part of the panel 210 is configured to be exposed from the frame structure when viewed in the lateral direction (see FIG. 7). Specifically, the first sealing material 229 is not provided at the end portion of the first panel receiving portion 225 in the lateral direction, so that the panel 210 is provided outside the end portion of the second frame 230. Is exposed (see reference numeral EP in FIG. 7). Water such as rainwater is more easily drained from the exposed portion EP.

Alternatively to this aspect, the first sealing material 229 may be provided at the end of the first panel receiving portion 225 in the lateral direction. In this case, since the panel 210 is covered with the first sealing material 229, it is not exposed to the outside of the first frame 220 and the second frame 230.

The panel-shaped module 20 may have a reinforcing member 240 provided on the back surface of the panel 210 (see FIG. 2). In the present embodiment, the reinforcing member 240 extends in the same direction as the second frame 230. The reinforcing member 240 may have a length in the lateral direction of 960 mm to 1000 mm, for example. Alternatively to this aspect, the reinforcing member 240 may extend in the same direction as the first frame 220.

FIG. 8 is a sectional view taken along the line 8A-8A in FIG. 2 and shows a sectional structure of the reinforcing member 240. FIG. 9 is a perspective view of the reinforcing member 240 according to the embodiment.

The reinforcing member 240 may have an upper portion 244 facing the panel 210, an upright portion 243 extending in a direction away from the panel 210, and a leg portion 242 located farthest from the panel 210. The leg portion 242, the upright portion 243, and the upper portion 244 may be integrally formed.

A cushioning material 260 may be provided between the upper portion 244 of the reinforcing member 240 and the panel 210. In this case, the upper portion 244 of the reinforcing member 240 may not be bonded to the panel 210. Alternatively, the upper portion 244 of the reinforcing member 240 may be joined to the panel 210 by a joining material. In this case, the type of bonding material is not particularly limited. For example, such a bonding material may be a silicone-based adhesive.

The leg 242 and the upper portion 244 extend substantially parallel to the panel 210. The upright portion 243 extends from the leg portion 242 to the upper portion 244 in a direction intersecting with the panel 210. More specifically, the upper portion 244 of the reinforcing member 240, the upright portion 243, and the leg portion 242 may form a substantially I-shaped shape in a sectional view (see FIG. 8 ).

The reinforcing member 240 has a hole 246 in the standing portion 243 through which a fastening member such as a bolt can be inserted. The hole 246 is surrounded by a C-shaped structure 247 in a cross-sectional view. The hole 246 of the reinforcing member 240 is aligned with the second hole 227 of the first frame 220. Similar to the fastening of the first frame 220 and the second frame 230, a fastening member such as a bolt passes through both the second hole portion 227 of the first frame 220 and the hole portion 236 of the reinforcing member 240. As a result, the first frame 220 and the reinforcing member 240 are fastened to each other. The reinforcing member 240 may be fastened to the first frame 220 at both ends thereof.

In the mode shown in FIGS. 8 and 9, the number of the second holes 227 formed in the first frame 220 may be the number of the reinforcing members 240, which is one in this example. In this case, since the number of the second holes 227 formed in the first frame 220 can be reduced as much as possible, the reduction in the strength of the first frame 220 due to the holes can be suppressed.

The shape of the reinforcing member 240 is not limited to the above shape. For example, FIGS. 10 and 11 show modified examples of the reinforcing member. FIG. 10 is a sectional view of a reinforcing member according to a modification. FIG. 11 is a perspective view of a reinforcing member according to a modification.

The reinforcing member 240 according to the modification has substantially the same shape as the reinforcing member shown in FIGS. 8 and 9. Therefore, in the following, only different shapes of the reinforcing member 240 according to the modification will be described in detail.

The reinforcing member 240 according to the modified example is provided with two hole portions 246 through which a fastening member such as a bolt can be inserted. Specifically, a C-shaped structure 247 in a cross-sectional view is formed on both sides of the upright portion 243, whereby two hole portions 246 are arranged in the lateral direction. In this case, the first frame 220 may have two second hole portions 227 that are arranged side by side in alignment with the positions of the two hole portions 246 of the reinforcing member 240. Accordingly, the reinforcing member 240 is fastened to the first frame 220 by the two fastening members. Therefore, in the present modification, the reinforcing member 240 can be firmly fastened to the first frame 220, and the displacement of the reinforcing member 240 in the rotational direction with respect to the first frame 220 can be suppressed.

(First modification)
FIG. 12 is a perspective view of the first frame 220 according to the first modification. The first frame according to the first modification has substantially the same shape as the first frame 220 shown in FIG. Therefore, in the following, only different shapes of the first frame 220 according to the first modification will be described in detail.

The first frame 220 according to the first modification includes the first panel receiving portion 225, the first upright portion 223, and the first leg portion 222, as described above. In the first modification, the first leg portion 222 extends from the first upright portion 223 in both the opening direction of the first panel receiving portion 225 and the direction opposite to the opening direction of the first panel receiving portion 225. ing. That is, the first leg 222 extends not only to the outside of the panel 210 but also to the inside of the panel 210. In this case, when the panel-shaped module 20 is loaded on a support member (not shown), the first leg 222 becomes easier to stabilize.

It is preferable that the first leg 222 has a notch 228 that is cut out so as not to interfere with the second frame 230 at the end in the lateral direction. Specifically, the cutout portion 228 may be provided at an end portion of the first leg portion 222 that extends toward the inside of the panel 210 in the lateral direction. The cutout portion 228 is such that the second frame 230 is the first contact portion 223a of the first frame 220 and the second contact portion 238 of the second frame 230 is in contact with each other. Interference with the legs 222 is prevented. The first frame 220 as described above can be manufactured by extruding and then removing the cutout portion 228.

The first flange 224 of the first frame 220 does not contact the second frame 230, and the first contact portion 223a is longer than the tip of the first flange 224 in the vertical direction when viewed from the direction orthogonal to the panel 210. Located on the outside. Therefore, the drainage gap SP is formed only by fastening the first frame 220 and the second frame 230 to each other. Even in this case, it is not necessary to introduce a step of forming a hole, a notch, or a groove for the purpose of forming a drainage channel in the first frame 220 or the second frame 230.

FIG. 13 is a side view of the first frame 220 according to the second modification. The first frame 220 according to the second modification shown in FIG. 13 has substantially the same shape as the first frame 220 shown in FIG. Therefore, in the following, only different shapes will be described in detail.

The first receiving portion 225 of the first frame 220 has a lateral “U” shape as described above. In the second modification, the upper bent portion 225a of the two

bent portions

225a and 225b of the laterally-shaped "U" shape is configured to have a thick wall. This makes it possible to maintain the strength of the curved portion 225a, whose strength is likely to decrease. In the present embodiment, the inner wall of the curved portion 225a, that is, the wall surface 225a1 facing the first receiving portion 225 may be formed in a flat shape without being rounded.

In FIG. 13, only the upper curved portion 225a of the two

curved portions

225a and 225b is thick. Alternatively, only the lower curved portion 225b of the two

curved portions

225a and 225b may be thick. Furthermore, both of the two

curved portions

225a and 225b may be configured to be thick. It should be noted that the curved portion having such a thick wall can be applied to the second frame 230.

As described above, the contents of the present invention have been disclosed through the embodiments, but it should not be understood that the description and drawings forming a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples and operational techniques will be apparent to those skilled in the art. Therefore, the technical scope of the present invention is defined only by the matters specifying the invention according to the scope of claims reasonable from the above description.

For example, in the above embodiment, the first frame 220 is arranged along the horizontal direction and the second frame 230 is arranged along the vertical direction. Alternatively, the first frame 220 may be arranged in the vertical direction and the second frame 230 may be arranged in the horizontal direction. In this case, the length of the first frame 220 in the extending direction and the length of the second frame 230 in the extending direction may be changed according to the length of the edge of the panel. It should be noted that the above-mentioned specific numerical values regarding the sizes of the respective portions of the first frame 220 and the second frame 230 are examples and can be changed as appropriate.

The features described in the above-described embodiments and modifications can be exchanged and/or combined as much as possible.

Further, the first frame 220 and/or the second frame 230 may have a grounding hole (not shown). In this case, the hole for grounding may be formed in the first upright portion 223 and/or the second upright portion 233, for example. Further, it is preferable that the hole for grounding is provided at a position where the stress applied to the first frame 220 and/or the second frame 230 due to the load is relatively low. As a result, it is possible to suppress a decrease in load resistance of the first frame 220 and/or the second frame 230 due to the holes. The position where the stress applied to the first frame 220 and/or the second frame 230 is relatively low is, for example, near the central portion in the height direction of the first upright portion 223 and the second upright portion 233.
