  The reinforcing member 50a is a member for physically reinforcing the first connecting member 20a and the photoelectric conversion module 10, and details thereof will be described later.

  The connecting portion 80 is a member for connecting the photoelectric conversion module 10 and the first connecting member 20a via the reinforcing member 50a, and details thereof will be described later.

  2A is a top view of the photoelectric conversion device 1a, and FIG. 2B is a cross-sectional view of the photoelectric conversion device 1a. In FIG. 2A, the solar cell panel 11 of the photoelectric conversion module 10 is omitted, and this is the same in FIG. 4 and FIG. FIG. 3 is a top view showing the reinforcing member 50a, the base material of the photoelectric conversion module 10, and the connecting portion 80 in a transparent manner in the configuration other than the main body 30a of the photoelectric conversion device 1a shown in FIG. is there.

  The photoelectric conversion module 10 in the photoelectric conversion device 1a has a thin panel shape, and the shape is not particularly limited. However, in addition to the rectangle shown in FIG. 2A, a polygon such as a hexagon, a circle, and the like are considered. It is done. The thickness of the photoelectric conversion module 10 is the thickness between the electrode substrates including the thickness of the electrode substrate itself of the solar cell, and for example, 3 mm or less is preferable from the viewpoint of manufacturing technology. The lower limit of the thickness of the photoelectric conversion module 10 is preferably about 10 μm. The photoelectric conversion module 10 may be covered with an exterior material for the purpose of imparting environmental resistance. Moreover, it is preferable that the photoelectric conversion module 10 has flexibility. In addition, as shown in FIG. 3, the solar cell panel 11 is arrange | positioned at the photoelectric conversion module 10. FIG. And the photoelectric conversion module 10 is provided with the extraction wiring 12 connected to the solar cell panel 11 and extended from the outer edge part of the photoelectric conversion module 10, as shown in FIG. The take-out wiring 12 can output the electric power generated by the solar cell panel 11 to the outside.

  The main body 30a may be configured to include the above-described components and a cover as illustrated in FIGS. 2 (a) and 2 (b). That is, the main body 30a shown in FIGS. 2 (a) and 2 (b) has a cover on the left side of the main body side connecting portion 31a. The main body 30a serves to protect the photoelectric conversion module 10 and the first connection member 20a when the photoelectric conversion module 10 is mounted. That is, the main body 30a in the photoelectric conversion device 1a shown in FIG. 2 is in a state in which the cover is open, and the first connection is thus made to the main body side connection portion 31a exposed in the state in which the cover of the main body 30a is open. The photoelectric conversion module 10 can be mounted via the member 20a. Then, by closing the cover of the main body 30a with the photoelectric conversion module 10 mounted, the photoelectric conversion module 10 and the first connection member 20a are sandwiched between the main body 30a and are protected from external impacts. be able to. In addition, in order that the main-body part 30a may exhibit such a protective function more, it is preferable to have rigidity.

  The first connecting member 20 a is coupled to the photoelectric conversion module 10 through a conductive member 81 provided in a connecting portion 80 that is coupled to the outer edge of the photoelectric conversion module 10. Specifically, when the photoelectric conversion module 10 has a rectangular shape, the first connecting member 20a is coupled to the photoelectric conversion module 10 via a conductive member 81 near the center of the left side. The first connecting member 20a is configured to be detachable from the main body 30a mechanically and electrically via the main body side connecting portion 31a of the main body 30a. The 1st connection member 20a and the main body side connection part 31a can be comprised by connectors, such as a card edge connector which can be repeatedly attached or detached from each other. Note that a conductive member 81 provided in the connecting portion 80 is connected to the first connecting member 20a. The first connecting member 20a shown in FIG. 2 is in a state of being detached from the main body side connecting portion 31a. For example, the first connecting member 20a is inserted into the main body side connecting portion 31a by sliding leftward from this state. It can be set as the structure mounted | worn. The same applies to FIGS. 4, 7, and 9.

  The first connection member 20a may have a connection mechanism including a guide and a connector. Specifically, the first connection member 20a has a guide and a connector provided at the tip of the guide, and the main body side connection portion 31a of the main body portion 30a serves as the guide of the first connection member 20a. You may have a guide rail which has a corresponding shape, and a main body side connector. In this case, the connector of the first connecting member and the main body side connector are connected by sliding the guide of the first connecting member 20a while being fitted to the guide rail of the main body side connecting portion 31a. . Thereby, the 1st connection member 20a and the main-body part 30a are physically connected between a guide and a guide rail, and can be electrically connected between a connector and a main body side connector.

  As shown in FIG. 3, the connecting portion 80 includes a flexible conductive member 81 and a connecting portion cover 82 that is covered to protect the conductive member 81, and has flexibility as a whole. In addition, the connection part cover 82 does not necessarily need to be provided. As shown in FIG. 3, the conductive member 81 has one end connected to the extraction wiring 12 extending from the outer edge of the photoelectric conversion module 10 and the other end connected to the first connection member 20a. Further, from the viewpoint of storage performance and durability of the conductive member, the connecting portion 80 is in contact with the reinforcing member 50a rather than the length a of the contacting portion with the reinforcing member 50a as shown in FIG. And the shortest length b between the contact portion with the photoelectric conversion module 10 is shorter. In addition, as for the connection part 80, it is preferable that the length a of the contact part with the reinforcement member 50a is more than the length of the 1st connection member 20a in the same direction. Thereby, the stress relaxation property of the connection part 80 can be improved.

  The reinforcing member 50a is a rigid member, and as shown in FIG. 3, covers the photoelectric conversion module 10 side of the first connecting member 20a (the side opposite to the connecting direction with the main body side connecting portion 31a). Is provided. Since the photoelectric conversion module 10 and the connecting portion 80 which are thin panel shapes are very thin, it is difficult to couple the first connecting member 20a to the outer edge portion of the photoelectric conversion module 10 via the connecting portion 80. By providing such a reinforcing member 50a, the first connecting member 20a can be reliably coupled to the photoelectric conversion module 10.

  The width of the reinforcing member 50a is not less than the width of the first connecting member 20a and less than 1/3 of the width of the photoelectric conversion module 10 in the left-right direction in the top view shown in FIG. It is preferable. Thereby, the portability can be improved by reducing the size in the top view of the photoelectric conversion device 1a while securing the reinforcing property of the photoelectric conversion device 1a.

  In addition, the photoelectric conversion device 1a includes the reinforcing member 50a. When the first connection member 20a is detached from the main body 30a, the photoelectric conversion device 1a is provided around the first connection member 20a. It is also possible to reduce the stress and prevent the photoelectric conversion module 10 from being bent. Furthermore, the photoelectric conversion device 1a includes such a reinforcing member 50a, thereby reducing the stress applied to the first connection member 20a itself or the connection portion between the first connection member 20a and the photoelectric conversion module 10. You can also.

  Further, the reinforcing member 50a has a rectangular shape having a long side in a direction orthogonal to the attaching / detaching direction and the vertical direction of the first connecting member 20a in the top view. In the present specification, the phrase “reinforcing member is provided so as to cover” means that the reinforcing member is provided so as to cover at least the upper part of the object, and all other than the upper part of the object. It is a concept including that the reinforcing member covers the direction. Further, in the vertical direction, the thickness of the reinforcing member 50 a is larger than the thickness of the photoelectric conversion module 10. Furthermore, in the vertical direction, the reinforcing member 50a has a thickness equal to or greater than the thickness of the first connecting member 20a. Thereby, the 1st connection member can be combined with photoelectric conversion module 10 more certainly.

  The reinforcing member 50a functions as a grip when the first connecting member 20a is attached to and detached from the main body 30a. That is, the first connecting member 20a is relatively small and is too close to the main body side connecting portion 31a of the main body portion 30a, so that it is difficult to grip. Moreover, since the photoelectric conversion module 10 has a thin panel shape and may have flexibility, when the photoelectric conversion module 10 is held and detached, the photoelectric conversion module 10 is not stable and may be damaged in the worst case. is there. On the other hand, the reinforcing member 50a is stable because it has rigidity, and is easier to grip because it is farther from the main body side connecting portion 31a than the first connecting member 20a. Furthermore, since the stress to the photoelectric conversion module 10 at the time of attachment / detachment is dispersed through the flexible connecting portion 80 by holding the reinforcing member 50a, damage to the photoelectric conversion module 10 can be suppressed.

  Further, as shown in FIGS. 2A and 2B, the reinforcing member 50a is directly coupled to the first connecting member 20a and is not directly coupled to the photoelectric conversion module 10. As a result, the flexible connecting portion 80 acts as a buffer material between the photoelectric conversion module 10 and the reinforcing member 50a, so that the reinforcing member 50a is gripped and the first connecting member 20a is detached from the main body portion 30a. In this case, the stress is not easily transmitted to the photoelectric conversion module 10. In addition, when the photoelectric conversion module 10 is attached to the main body 30a via the first connecting member 20a, the connecting portion 80 similarly functions as a buffer material, and an impact applied to the main body 30a is photoelectrically converted. It becomes difficult to be transmitted to the module 10.

  By the way, the photoelectric conversion device 1a may further include a third connection member that is provided on the reinforcing member 50a or the main body 30a and that can mechanically detach the photoelectric conversion module 10 or the reinforcing member 50a and the main body 30 from each other. Good. For example, as shown in FIG. 4A, the reinforcing member 50a is provided on the same end surface as the first connecting member 20a, and the first connecting member 20a is attached to and detached from the main body 30a. You may provide the 3rd connection member 60a which can be attached or detached with the main-body part 30a in conjunction with. In this case, a connection portion corresponding to the third connection member 60a may be provided in the main body portion 30a. Further, for example, as shown in FIG. 4B, a third connection member 60b provided in the main body 30a and capable of sandwiching the photoelectric conversion module 10 like a binder may be provided. As described above, according to the photoelectric conversion devices 1b and 1c further including the third connection member, the main body 30a and the photoelectric conversion module 10 are integrated with the photoelectric conversion module 10 mounted on the main body 30a. Can increase the sex.

  The 1st connection member 20a, the 2nd connection member 36, and the 3rd connection member 60a may be equipped with the lock mechanism which fixes and holds the mechanical connection state to a to-be-connected body. Any known mechanism can be applied to the lock mechanism, but for example, a mechanism using a lock claw and a claw engaging portion that engages with the lock claw can be applied.

  In addition, as a first modification of the photoelectric conversion device 1a, the photoelectric conversion module 10 has a circular shape, not a rectangular shape, and a shape that conforms to the shape of the photoelectric conversion module 10 in a state where the main body 30a is closed (illustrated) (Omitted) can also be used. Even in such a photoelectric conversion device, the shape of the reinforcing member 50a is not particularly limited, but has a shape along the shape of the main body 30a and a shape along the shape of the outer edge of the photoelectric conversion module 10. It may be. Thereby, size reduction as the whole photoelectric conversion apparatus 1a can be achieved.

  Further, as a second modification of the photoelectric conversion device 1a, as shown in FIG. 5, the first connection member 20b provided below from the bottom surface of the reinforcing member 50b is used instead of the first connection member 20a, and Instead of the main body side connection part 31a, the photoelectric conversion device 1e using the first connection member 20b and the main body side connection part 31b that can be attached and detached can be used. Thereby, when the first connecting member 20b and the main body 30b are detached, the stress is not easily transmitted to the photoelectric conversion module 10.

  Further, as a third modification of the photoelectric conversion device 1a, as shown in FIG. 6, a photoelectric conversion module group 70 including the photoelectric conversion module 10 is provided, and the photoelectric conversion module group 70 can be folded between adjacent photoelectric conversion modules. In addition, the reinforcing member 50c may be the photoelectric conversion device 1f having a thickness equal to or larger than the thickness when the photoelectric conversion module group 70 is folded. Here, in addition to the photoelectric conversion module 10, the photoelectric conversion module group 70 includes a first module group coupling unit 71, a first additional photoelectric conversion module 72, a second module group coupling unit 73, and a second module group coupling unit 71. The additional photoelectric conversion module 74 is provided. The first additional photoelectric conversion module 72 and the second additional photoelectric conversion module 74 have a thin panel shape like the photoelectric conversion module 10, and can each be provided with the solar cell panel 11 to generate electric power. The first module group connecting portion 71 and the second module group connecting portion 73 are for connecting the respective photoelectric conversion modules, and are composed of a flexible conductive member or the like, through these, The electric power generated by the first additional photoelectric conversion module 72 and the second additional photoelectric conversion module 74 is output to the first connection member 20c. Note that the number of additional photoelectric conversion modules is not limited to two, and may be one or three or more.

  Further, as shown in FIG. 6B, the shortest length between the contact portion with the reinforcing member 50c and the contact portion with the photoelectric conversion module 10 is c, and the distance between adjacent photoelectric conversion modules is d. In some cases, c ≧ d / 2. Accordingly, when the photoelectric conversion module group 70 is folded as shown in FIG. 6A, the bent second module group connecting portion 73 is not affected by the shape or the like of the reinforcing member 50c and overlaps the reinforcing member 50c. Can be folded without

  Thus, the photoelectric conversion module group 70 is in a state in which the photoelectric conversion module group 70 is folded and accommodated by setting the reinforcing member 50c of the photoelectric conversion device 1f to a thickness equal to or larger than the thickness when the photoelectric conversion module group 70 is folded. Can be properly protected.

  Moreover, as a fourth modification of the photoelectric conversion device 1a, as shown in FIG. 7A, a photoelectric conversion module group 70 ′ having flexibility is provided, and the photoelectric conversion module group 70 ′ can be wound and stored. It is also possible to use the device 1g. At this time, as shown in FIG. 7B, in the vertical direction, the reinforcing member 50d of the photoelectric conversion device 1g has a thickness equal to or larger than the thickness at the time of winding of the photoelectric conversion module group 70 ′, so that the photoelectric conversion module In a state where the group 70 ′ is wound and housed, the photoelectric conversion module group 70 ′ can be appropriately protected. The same effect can be obtained when a single photoelectric conversion module having flexibility is provided instead of the photoelectric conversion module group 70 ′.

  Moreover, as a modification 5 of the photoelectric conversion device 1a, as shown in FIG. 8, instead of the first connection member 20a, the reinforcing member 50a is connected in a direction orthogonal to the direction connecting to the photoelectric conversion module 10 and the vertical direction. It is also possible to provide a photoelectric conversion device using the first connection member 20e provided on the side surface along. This makes it difficult for stress to be transmitted to the photoelectric conversion module 10 when the first connecting member 20e and the main body (not shown) are attached and detached.

  Furthermore, as a sixth modification of the photoelectric conversion device 1a, as shown in FIG. 9, a first female connection member 20f is used instead of the first connection member 20a, and the first connection member 31a is used instead of the first connection member 20a. It is also possible to use a male main body side connecting portion 31e to which the connecting member 20f can be attached and detached.
