Hereinafter, the state in which the interface 21 is expanded linearly is abbreviated as “deployed state” as appropriate.

  Further, the interface 21 may be provided with a lock mechanism for holding each first rigid member 211 in a folded state. For example, as shown in FIG. 5, the first rigid member 211a and the first rigid member 211b are in contact with each other in a folded state, and the first rigid member 211b and the first rigid member 211c are in a folded state. By providing the magnets M at the locations where they come into contact, the first rigid member 211 may be kept folded.

  Further, for example, the first rigid member 211a and the first rigid member 211b are in contact with each other in a folded state, and the first rigid member 211b and the first rigid member 211c are in contact with each other in a folded state, respectively. You may make it hold | maintain the state by which each 1st rigid member 211 was folded by providing an engaging mechanism (for example, nail | claw and nail | claw engaging part).

  Further, the interface 21 may be provided with a lock mechanism for holding each first rigid member 211 in a linearly expanded state (deployed state). For example, similarly to the lock mechanism for holding the folded state of each first rigid member 211 described above, a magnet M is provided at a location where the first rigid members 211 are in contact with each other in the expanded state, or an engagement mechanism is provided. Thus, the unfolded state may be held.

  As described above, by providing the interface 21 with the lock mechanism, the state in which each first rigid member 211 is folded or spread linearly is prevented from being released against the user's intention. Can do. In particular, the interface 21 is provided with a lock mechanism for holding the unfolded state, so that when the user puts the photoelectric conversion device 1 into the housed state from the use state, the user first folds the guide unit 40 first. The interface 21 can be guided to a preferred folding procedure of folding.

  As shown in FIGS. 7 and 8, for example, the interface 21 has a release unit (operation unit) 220 as a lock mechanism for holding the unfolded state, and holds the unfolded state by the release operation by the release unit 220. You may provide the lock mechanism to cancel | release.

  FIGS. 7A and 7B are (a) a top cross-sectional view and (b) a side cross-sectional view when the interface 21 is provided with a lock mechanism 217 having a releasing means and the lock mechanism 217 is in a holding state. FIGS. 8A and 8B are (a) a top cross-sectional view and (b) a side cross-sectional view when the interface 21 is provided with a lock mechanism 217 having a release means, and the lock mechanism 217 is in a release state.

  As shown in FIGS. 7 and 8, the lock mechanism 217 includes an engagement protrusion 218, a locking recess 219, and an operation unit 220. The engagement protrusion 218 is provided inside one first rigid member 211 (first rigid member 211b in this example) via an elastic member, and the other first rigid member 211 (first in this example) is provided by the elastic member. It is biased in the direction of the rigid member 211a). The locking recess 219 is a recess provided in the first rigid member 211a, into which the engagement protrusion 218 can be inserted. The operation unit 220 is connected to the engagement protrusion 218 and protrudes from the side surface in the column direction of the first rigid member 211b. The operation unit 220 moves when an external force is applied by a user operation or the like, and the engagement protrusion 218 moves in the connecting direction of the first rigid member 211 in conjunction with the operation unit 220.

  In the unfolded state, as shown in FIG. 7, the engaging protrusion 218 is urged by the elastic member and is inserted into the locking recess 219. Accordingly, the first rigid members 211a and 211b are prevented from being folded via the first connecting portion 216a, and the interface 21 is maintained in the unfolded state.

  Further, for example, when the operation unit 220 is moved by an external force applied by a user operation or the like, as shown in FIG. 8, the engagement protrusion 218 is disengaged from the locking recess 219 (release operation). As a result, the hold of the expanded state is released. That is, the unfolded state is released by a release operation different from the operation of folding the first rigid member 211.

  When the first rigid members 211a and 211b are bent via the first connecting portions 216a, the engaging protrusions 218 protrude from the first rigid member 211b, but the first rigid members 211a and 211b are expanded. As this is done, the engaging projection 218 is pushed into the first rigid member 211a. When each of the first rigid members 211a and 211b is linearly expanded (deployed state), the engaging protrusion 218 is inserted into the locking recess 219. As described above, the unfolded state can be maintained without requiring a special operation only by spreading the first rigid members 211a and 211b linearly.

  As described above, according to the interface 21 having the release unit 220 and provided with the lock mechanism 217 for releasing the hold of the expanded state by the release operation by the release unit 220, the release unit 220 is used when folding from the expanded state. Although a release operation is required, no special operation is required when changing from the folded state to the expanded state. Therefore, when the user changes the photoelectric conversion device 1 from the use state to the housed state, the user can be further guided to a suitable folding procedure in which the user first folds the guide portion 40 and then the interface 21. In addition, when the storage state is changed to the use state, the interface 21 can be easily set in the expanded state.

  Next, with reference to FIG. 9 to FIG. 11, a process in which the photoelectric conversion device 1 according to the present embodiment is folded from the use state to be in the housed state will be described.

  Fig.9 (a) is a top view in the use condition of the photoelectric conversion apparatus 1 which concerns on this embodiment, FIG.9 (b) is a front view in the use condition of the photoelectric conversion apparatus 1 which concerns on this embodiment. FIG. 10A is a top view of the photoelectric conversion device 1 according to the present embodiment in the column direction folded state, and FIG. 10B is a column direction folded state of the photoelectric conversion device 1 according to the present embodiment. FIG.

  Here, the column direction folded state of the photoelectric conversion device 1 means that the photoelectric conversion modules 1 in the respective rows are gathered together according to the folding direction limited by the guide unit 40 from the use state shown in FIG. This is a state in which the photoelectric conversion modules P in all rows are overlapped with the photoelectric conversion modules P in rows connected to the interface 21 by being alternately folded in the column direction.

  In this example, the photoelectric conversion module P (P31, P32, P33) in the third row is folded so as to overlap the back side of the photoelectric conversion modules P (P21, P22, P23) in the second row, and these are collectively collected in the first row. The photoelectric conversion modules P (P11, P12, P13) are folded so as to overlap the front side.

  FIG. 11A is a top view of the photoelectric conversion device 1 according to the present embodiment in the accommodated state, and FIG. 11B is a front view of the photoelectric conversion device 1 according to the present embodiment in the accommodated state.

  Here, the storage state of the photoelectric conversion device 1 means that the photoelectric conversion module 1 is connected to the photoelectric conversion module P in each column according to the folding direction limited by the interface 21 from the column direction folded state shown in FIG. In addition, it is a state in which all photoelectric conversion modules P are overlapped by being alternately folded in the row direction.

  In this example, first, in conjunction with the folding of the first connecting portion 216b of the interface 21, the third row of photoelectric conversion modules P (P13, P23, P33) that overlap in the vertical direction are overlapped in the second row. The photoelectric conversion modules P (P12, P22, P32) are folded so as to overlap the back side. The second row of photoelectric conversion modules P (P12, P13, P22, P23, P32, P33) overlapped in the vertical direction in conjunction with the folding of the first connecting portion 216a of the interface 21 are collectively collected in the first row. In this state, the photoelectric conversion modules P (P11, P21, P31) are folded so as to overlap the front side.

  As described above, when the photoelectric conversion device 1 is changed from the use state to the housed state, the photoelectric conversion modules P together with the guide unit 40 are collectively folded in the column direction, and the photoelectric conversion modules P in all rows are interfaced 21. After being superposed on the photoelectric conversion modules P connected to each other (column direction folded state), the photoelectric conversion modules P in each column are folded alternately in the row direction together with the interface 21, and all the photoelectric conversion modules P are overlaid. This is the preferred folding procedure.

  Next, a usage example of the photoelectric conversion device 1 according to this embodiment will be described.

  The photoelectric conversion device 1 may include a support portion 301 that supports the photoelectric conversion device 1. Thereby, for example, as shown in FIG. 12, when the user is at home, the photoelectric conversion device 1 is installed in the vicinity of the window 302 via the support portion 301 in a use state. For example, when the photoelectric conversion module connector 10 is used in a planar shape on a desk or the like, the photoelectric conversion module connector 10 takes up space. Then, as shown in FIG. 12, the photoelectric conversion apparatus 1 (photoelectric conversion module coupling body 10) is suspended and supported, so that space saving during installation can be achieved.

  Next, a modification of the photoelectric conversion device 1 according to this embodiment will be described.

  In the photoelectric conversion device 1, each second rigid member 41 constituting the guide portion 40 does not necessarily have to be directly connected to the photoelectric conversion module P disposed at the row direction end of the photoelectric conversion module connector 10. For example, as shown in FIG. 13, it may be indirectly connected via the flexible member 43 (Modification 1).

  Further, in the photoelectric conversion device 1, each second rigid member 41 constituting the guide portion 40 needs to extend over the entire side surface of the photoelectric conversion module P disposed at the row direction end of the photoelectric conversion module connector 10. For example, as shown in FIG. 14, as long as it is connected to the second connecting portion 42, it may not be provided in other places (Modification 2). Thereby, size reduction and weight reduction of the photoelectric conversion apparatus 1 can be achieved.

  Further, in the photoelectric conversion device 1, the second connecting member Q is not necessarily provided between all the photoelectric conversion modules P. For example, as illustrated in FIG. 15, other than between the photoelectric conversion modules P in the row farthest from the interface 21. The second connecting member Q may not be provided (Modification 3). Thereby, size reduction and weight reduction of the photoelectric conversion apparatus 1 can be achieved.

  In the photoelectric conversion device 1, for example, as illustrated in FIG. 16, the guide unit 40 and the interface 21 may be connected to each other or may be integrally formed (Modification 4). Thereby, the whole photoelectric conversion apparatus 1 is stabilized and handling property improves.

  Here, referring to FIG. 17 and FIG. 18, in the photoelectric conversion device 1 according to the modified example 4, the interface 21 has a lock mechanism for holding the state where each first rigid member 211 is linearly expanded. An example (part 1) provided will be described. In FIG. 17, for the sake of simplicity, the components other than the interface 21 and the guide unit 40 are not shown.

  As shown in FIG. 17, the first rigid member 211a constituting the interface 21 includes a switch 221 that protrudes to a place where the second rigid member 41b constituting the guide portion 40 is arranged in the folded state. In the state shown in FIG. 17, the first rigid members 211a and 211b are kept in a state of being linearly expanded and cannot be folded. However, when the guide portion 40 is folded and the switch 221 is pushed into the first rigid member 211a by the second rigid member 41b, the first rigid members 211a and 211b are released from being held in a linear shape. It becomes possible to fold.

  Next, the mechanism of such a locking mechanism will be described with reference to FIG. The lock mechanism 217 includes an engagement protrusion 218, a locking recess 219, and a switch 221. The engagement protrusion 218 is provided inside the first rigid member 211a and is urged in the same direction by an urging member 222 that is urged in the direction of the switch 221 (downward in FIG. 18) by an elastic member.

  The first rigid member 211a is provided with a path restricting portion 223 formed in, for example, a groove shape, and the engaging protrusion 218 is constrained by inserting a protrusion into the path restricting portion 223, for example. Yes.

  Specifically, when the engaging protrusion 218 is urged by the urging member 222 and moves in the direction of the switch 221, it simultaneously moves in the right direction in FIG. 18 and is a recess provided in the first rigid member 211b. A part is inserted into a certain locking recess 219 (FIG. 18A). As a result, the first rigid members 211a and 211b are held in a state of being linearly expanded.

  Further, when the switch 221 is pushed into the first rigid member 211a and the engagement protrusion 218 moves in the direction opposite to the direction of the switch 221, it simultaneously moves in the left direction in FIG. (FIG. 18 (b)). Accordingly, the first rigid members 211a and 211b are released from being held in a linear shape.

  As described above, when the guide portion 40 is in a state other than the folded state, the first rigid members 211a and 211b are maintained in a linearly expanded state, but the guide portion 40 is folded and the switch 221 is in the first state. When the first rigid member 211a is pushed into the first rigid member 211a, the first rigid members 211a and 211b are released from being held in a linear shape. Therefore, without complicating the operation, the user can be guided to a preferred folding procedure in which the interface 21 is folded after the guide unit 40 is folded.

  Here, with reference to FIG. 19 and FIG. 20, in the photoelectric conversion device 1 according to the modified example 4, the interface 21 has a lock mechanism for holding the state in which the first rigid members 211 are linearly expanded. An example (part 2) provided will be described. In FIG. 19, for the sake of simplicity, the components other than the interface 21 and the guide unit 40 are not shown.

  As shown in FIG. 19, the second rigid member 41a constituting the guide portion 40 includes a switch 44 that protrudes to a place where the second rigid member 41b is arranged in the use state. In the state shown in FIG. 19, the first rigid members 211a and 211b are released from being held in a linear shape and can be folded. However, when the guide portion 40 is in a use state and the switch 44 is pushed into the second rigid member 41a by the second rigid member 41b, the first rigid members 211a and 211b are released from being held in a linear shape. And can be folded.

  Next, the mechanism of such a locking mechanism will be described with reference to FIG. The lock mechanism 217 includes a switch 44, a connecting rod 45, an engagement protrusion 218, a locking recess 219, and a shaft portion 224.

  The switch 44, the connecting rod 45, the shaft portion 224, and the engaging protrusion 218 are connected in this order. The shaft portion 224 can rotate around the vertical direction. Further, the switch 44 is urged in the direction (discharge direction) from the second rigid member 41a by the elastic member.

  In a state where no external force is applied to the switch 44, as shown in FIG. 20A, the switch 44 protrudes in the discharge direction by the elastic member, and the engagement protrusion 218 is disengaged from the locking recess 219. . Thereby, holding | maintenance of the state expanded to the linear form of 1st rigid member 211a, 211b is cancelled | released.

  On the other hand, when an external force is applied to the switch 44 and pushed in the direction of the rigid member 41a, the connecting rod 45 is also pushed in as shown in FIG. As a result, the shaft portion 224 rotates clockwise in FIG. 20, and in conjunction with this, the engaging protrusion 218 moves in the direction of the first rigid member 211 b and is inserted into the locking recess 219. Thereby, the state where the first rigid members 211a and 211b are linearly expanded is maintained.

  As described above, when the guide portion 40 is in use, that is, in the expanded state, the switch 44 is pushed into the second rigid member 41a, and the first rigid members 211a and 211b are linearly expanded. Although it is held, when the guide unit 40 is in a state other than the use state, the first rigid members 211a and 211b are released from being held in a linear shape. Therefore, it is possible to guide the user to a suitable folding method in which the interface 21 is folded after the guide portion 40 is folded.

  The photoelectric conversion module P included in the photoelectric conversion device 1 has been described as having a rectangular shape in the top view. However, the photoelectric conversion module P is not limited to such a shape. For example, a polygon such as a hexagon or a circle as illustrated in FIG. It may be.

  Moreover, the photoelectric conversion module coupling body 10 and the main body 20 provided in the photoelectric conversion device 1 may be configured to be detachable from each other via the photoelectric conversion module IF 12 and the interface 21. The attachment / detachment mechanism is not particularly limited. For example, the photoelectric conversion module IF12 includes a guide 121 and a connector 122 provided at the tip of the guide 121 as shown in FIG. As shown, the guide rail 212 having a shape that restricts the guide 121 to move in only one direction and the main body side connector 213 to which the connector 122 can be connected may be provided.

  In this case, the connector 121 of the photoelectric conversion module IF12 and the main body side connector 213 of the interface 21 are connected by sliding the guide 121 of the photoelectric conversion module IF12 while being fitted to the guide rail 212 of the interface 21. The Accordingly, the photoelectric conversion module IF12 and the interface 21 are physically connected between the guide 121 and the guide rail 212, and are electrically connected between the connector 122 and the main body side connector 213.

  In the photoelectric conversion device 1, as shown in FIGS. 24 and 25, the photoelectric conversion module P arranged at the end in the column direction may be directly connected to the interface 21 without passing through the photoelectric conversion module IF 12. At this time, for example, as shown in FIG. 24, in order to avoid the first connecting member 13 between the photoelectric conversion modules P in the second row and the third row in contact with the interface 21 in the housed state, The conversion module P (P11, P12, P13) may be configured to be longer in the column direction than the other photoelectric conversion modules P. By directly connecting the photoelectric conversion module P to the interface 21 in this way, it is possible to suppress twisting between the photoelectric conversion module P and the interface 21.

  Moreover, in order to avoid the 1st connection member 13 between the photoelectric conversion modules P of the 2nd row and the 3rd row contacting the interface 21, for example, as shown in FIG. A recess for accommodating the first connecting member 13 may be formed in a part of the interface 21. Thereby, in addition to being able to suppress that twist arises between photoelectric conversion module P and interface 21, further miniaturization of photoelectric conversion device 1 can be attained.

  In addition, the photoelectric conversion device 1 may function as a first guiding unit that guides the folding direction of the photoelectric conversion device 1 in the row direction by causing the first connecting portion 216 to remain bent in a specific direction. . Specifically, for example, by bending a shape that is curved so that the first connecting portion 216 is easily bent to either the front side or the back side, the bending fold can be left. In this case, the first connecting portion 216 preferably uses, for example, resin, cloth, leather, or the like as the covering member in order to leave the bending wrinkles.

  Furthermore, the photoelectric conversion device 1 may function as a second guiding unit that guides the folding direction of the photoelectric conversion device 1 in the column direction by causing the first connecting member 13 to remain bent in a specific direction. . Specifically, for example, by bending the first connecting member 13 so as to be easily bent to either the front side or the back side, a bent shape can be left.

  In this case, it is preferable that the first connecting member 13 uses, for example, resin, cloth, leather, or the like as a covering member in order to leave bent wrinkles. In addition, when making the 1st connection member 13 function as a 2nd guidance | induction means, the photoelectric conversion apparatus 1 does not necessarily need to be provided with the guide part 40. FIG.

  The above description shows only one embodiment of the present invention, and it goes without saying that various modifications may be made within the scope of the claims. For example, although the arrangement of each photoelectric conversion module P, the second connecting member Q, and the like has been described using rows and columns, the rows and columns are defined for convenience of description, and these may be interchanged. Moreover, although the photoelectric conversion module P was demonstrated using the photoelectric conversion module coupling body 10 which arranged 3 rows and 3 columns, the number of rows and the number of columns of the photoelectric conversion module P shall be arbitrary integers of 2 or more, respectively. Can do.

  ADVANTAGE OF THE INVENTION According to this invention, the photoelectric conversion apparatus which can attain the improvement of the storage property at the time of non-use and size reduction at the time of use can be provided.
