[0005] An object of the present application is to provide a solar cell unit-equipped blind in which solar cell units and between a solar cell unit and each component can be mechanically and electrically inserted and removed freely and are suspended in a connected state.

[0006] Against the above background, · Small unit work is possible, and a connection structure as a large-scale solar cell system can be achieved by simple installation, so it can also be installed on existing blinds. · Easy removal enables troubleshooting. There are such requirements. In view of such requirements, the present application presents the following features. A. The solar cell unit has a circuit board with solar cells in a housing (container). <Easy during production> B. Between the housings of a plurality of solar cell units, they are freely insertable and removable by fitting in a male-female relationship with each other. When inserted, the housings communicate with each other, and at the same time as the mechanical connection between the housings, the connection of the wiring of the solar cells between the housings can also be achieved at the same time. Therefore, depending on the number of solar cell units, the scale can be freely expanded or reduced.

Modes for Carrying Out the Invention

[0020] FIG. 1 is a view showing an embodiment of a blind equipped with a solar cell unit according to the present invention. 1-A shows a blind 100 having a number of slats. The slats are provided with a number of solar cell units. Since it is a solar cell attached to the slat, a thin film solar cell such as a perovskite solar cell is used. The technical features of the present application will be described in the enlarged view of 1-B. (a) is a perspective view of the blind 100 having a number of slats of 1-A, and a number of slats are hanging down. (c), (d), and (e) describe one of them as a representative. (c) is a view seen from the indoor side without sunlight, and the back side of the housing of each solar cell unit can be seen. (d) and (e) are views seen from the outdoor side with sunlight, and the front side of the housing of each solar cell unit can be seen. The difference between (d) and (e) is that the solar cell is shifted from the center in the width direction of the unit (the left-right direction in the figure) in the solar cell unit. This is an arrangement that avoids positions where it is likely to be shaded between the slats depending on the direction of the slats. It is not essential but is a convenient arrangement. In addition, (b) shows only the extracted slats.

[0021] The feature of the solar cell unit-equipped blind according to the present invention is a vertical blind in which the slats are passed through a plurality of solar cell units in series and the solar cell units are connected. For example, when (e) is taken as an example, it is as follows. In (e), Each of the solar cell unit 120, the connecting part 130, and, if necessary, the length adjusting part 140 between the solar cell unit 120 and the connecting part 130 has a housing provided with a fitting groove 123 for holding through the slat 110. In a form sandwiching the slat 110, the above units 120, 130, and 140 are connected in the longitudinal direction so as to be insertable and removable, and each is not fixedly configured on the slat 110. Further, by providing a stopper part 150 having a size larger than the fitting groove at the lower part of the slat 110, the solar cell unit 120 is in a state of not falling off from the slat 110. In addition, the connecting part 130 is to be inserted from the upper part of the slat 110. As described above, since the blind is suspended at the upper part in a configuration where a plurality of thin-plate-like slats are connected in series to a plurality of solar cell units, loads such as the solar cell units 120, the connecting parts 130, and, if necessary, the length adjusting parts 140 are applied to the slats 110 and the lowermost stopper parts 150, and do not apply to the solar cell units 120, the connecting parts 130, and, if necessary, the length adjusting parts 140, etc. As described above, in the configuration of the present application, unlike the conventional example where the solar cell units 120 are fixed to the slats 110, between the slats 110 and the solar cell units 120 (similarly for the connecting parts 130 and the adjusting parts 140), since they are in a contact state that can be inserted and removed through the fitting grooves of the housing, it is possible to easily attach and remove even only some of the units. Further, the solar cell units 120 are made in small-scale units, facilitating the attachment and replacement at the installation site to the slats 110. In (f), one solar cell unit 120 and the slat 110 are shown enlarged. In addition, it is desirable that between the solar cell units 120, and between the solar cell units 120 and the connecting parts 130, not only mechanical connection (disconnection) but also electrical connection (disconnection) are simultaneously performed by insertion (extraction) between them. This will be described in detail with reference to FIG. 5.

[0022] The technical features of the present application will be further described with reference to FIG. 2. FIG. 2 is a diagram showing an embodiment of a detachable fitting structure between a solar cell unit and a slat of a solar cell unit-equipped blind according to the present invention. In 2-A, the figure of 1-B (f) in FIG. 1 is shown. In 2-B, a cross-sectional view taken in the horizontal direction cut along the arrow B-B is shown, and in 2-C and 2-D, cross-sectional views taken in the vertical direction cut along the arrow A-A are shown. The solar cell unit 120 has a solar cell substrate 121 having a solar cell 121A and a circuit board 121B on which the solar cell is provided, and a housing 122 that houses the solar cell substrate 121. The housing 122 or the circuit board 121B has a connecting means 124 for connecting and detaching by mechanical insertion and removal between the solar cell units 120, or between the solar cell unit 120 and the connecting component 130 or the length adjusting component 140, and further has a fitting groove 123 for fitting and passing through the slat 110. In addition, in the connection by the connecting means 124, it is desirable that the electrical connection between each other is also made at the same part together with the mechanical connection. Of course, it is natural that the mechanical connection and the electrical connection may be made at different parts. In the case of the same part, for example, in the electrical connector attached to the electrical board, the electrical connection and the mechanical connection can be achieved simultaneously by insertion. In 2-B, the situation of the connecting means 124 and the slat 110 will be understood, and in 2-C and 2-D, the situation of the fitting groove 123 of the slat 110 and the slat 110 will be understood. In addition, the difference between 2-C and 2-D is that in 2-C, there is a cover (referred to as the decorative cover 210) on the surface side of the housing 122 (the outer side where the sun shines), but in 2-D, there is no decorative cover, and various deformations that are not related to the function are possible.

[0023] In FIG. 1, it is shown that the solar cell unit 120 has a state of not falling off from the slat 110 by providing a stopper component 150 having a size larger than the fitting groove 123 at the lower part of the slat 110. This situation will be described with reference to FIG. 3. FIG. 3 is a diagram showing an embodiment of the insertion and removal between the solar cell unit and the slat and the stopper component of the solar cell unit-equipped blind according to the present invention. In 3-A, the solar cell unit 120 and the slat 110 show a situation where they have not been inserted yet. At the lower end of the slat 110, there is a stopper component 150 having a size larger than the fitting groove. The size larger than the fitting groove means a size larger than the groove width W and the groove thickness T, which are the sizes of the fitting groove 123 in the figure.

[0024] In 3-B, the solar cell unit 120 is in a state of passing through the slat 110. However, when the solar cell unit 120 hits the large-sized stopper component 150, it can no longer move and stops. If the lowermost solar cell unit 120 stops, naturally, the solar cell units 120 connected above it cannot move either. Therefore, for each solar cell unit 120, fixing between the slats is unnecessary. Furthermore, when it is desired to remove the solar cell unit 120 for replacement or the like, it may be removed from the upper side of the slat, or it is also possible and easy to remove it from the lower side by removing the stopper component 150 from the slat 110. Since the slat 110 is inserted into and removed from the fitting groove of the solar cell unit 120 in a freely insertable and removable manner, it is necessary that the slat width WS and the slat thickness TS of the slat 110 are smaller than the groove width W and the groove thickness T of the fitting groove 123 with a desired margin. Having a desired margin means that if it is too small, it will fall out, so it should be such that it does not fall out, and if there is no margin, it is difficult to pass through, so it should be such that it is easy to pass through. Furthermore, in order for the slat 110 not to fall out in the back surface direction of the solar cell unit 120, it is necessary that the fitting groove 123 has no opening in the back surface direction, or if there is an opening, its dimension is such that the slat 110 cannot fall out. A fitting groove configuration such as providing an L-shaped protrusion 125 is required so that the opening width WO is smaller than the slat width WS.

[0025] In 3-C, when the number of solar cell units 120 is large, in order to reduce the load on the stopper component 150 and the slat 110, an example is shown where a relay stopper component 151 that serves as a relay stopper is attached at an appropriate intermediate position. For example, when the relay stopper component 151 is inserted every three solar cell units 120, only the load of the three solar cell units 120 is applied to each relay stopper component 151, the stopper component 150, and the slat 110. If not, when ten solar cell units 120 are attached, the load of ten units will be applied to the lowermost stopper component 150 and the slat 110. In addition to serving the same stopper role as the stopper component 150, the relay stopper component 151 desirably has a fitting groove 123 for passing through the slat 110, like the solar cell unit 120, the connecting component 130, and the length adjustment component 140, as a relay function, and also has a connecting means 124 to perform both mechanical connection and electrical connection functions. Incidentally, regarding the way the stopper component 150 and the relay stopper component 151 contact the slat 110, various means can be considered, such as making each of the stopper component 150 and the relay stopper component 151 into two upper and lower plates to tightly sandwich the slat 110, providing a hole (a horizontally long hole is preferable) in the slat 110, and covering the upper plate as a lid with the protrusion protruding from the lower plate of the stopper component 150 and the relay stopper component 151 passed through the hole. The attachment and detachment of the stopper component 150 and the relay stopper component 151 to the slat 110 can be easily achieved with a single screw or a one-push handle.

[0026] FIG. 4 is a diagram showing a photograph of an embodiment of the solar cell unit and the slat of the solar cell unit-equipped blind according to the present invention. 4-B shows the diagram of 1-B(f) in FIG. 1. The part of the solar cell unit 120, the front side where the solar cells can be seen, is shown in 4-C, and the back side is shown in 4-D. In 4-C, the housing 122 having a light transmission opening for the solar cells can be confirmed, and in 4-D, the L-shaped protrusion 125 for the fitting groove 123 of the slat 110 and the housing 122 can be confirmed. 4-A is a photograph of only the solar cell substrate 121 having the solar cell 121A and the circuit board 121B equipped with this.

[0027] FIG. 5 is a diagram showing an embodiment of the connection structure and electrical wiring of the length adjustment component and the connection component inside the solar cell unit of the solar cell unit-equipped blind according to the present invention. 5-A shows an overview of the electrical wiring within the solar cell unit 120. In this example, four solar cells 121A are wired in series, and the upper and lower wirings can each be connected to other solar cell units 120 via the connection terminals 124. The connection terminals 124 are preferably of a dual-purpose type that can make both mechanical and electrical connections simultaneously, but they can also be separate. 5-C shows the connecting component 130. The connecting component 130 is connected to the uppermost part of the solar cell unit 120 and includes an external wiring terminal 510 which is a lead-out terminal for external wiring. It does not have the solar cells 121A. Only one side of the connection terminal 124 is necessary. For the convenience of wiring, one of the external wiring terminals 510 may be on the back side. 5-B shows the length adjustment component 140. For example, when the sunlight exposure of the upper part above the slats 110 is not good depending on the installation conditions of the blind, this part is desired to be connected without having the solar cells 121A. Therefore, compared to the solar cell unit 120, the length adjustment component 140 has only the desired length and does not have the solar cells 121A. Naturally, the length adjustment component 140 is inserted and connected between the connecting component 130 and the solar cell unit 120 for use as needed. Naturally, like the connecting component 130 and the solar cell unit 120, both mechanical and electrical connections are made. The fitting relationship with the slats 110 is exactly the same for both the connecting component 130 and the length adjustment component 140 as that of the solar cell unit 120 with the slats 110 shown in FIG. 2, FIG. 3, etc. The connecting component 130 and the length adjustment component 140 have fitting grooves 123.

[0028] FIG. 6 is a diagram showing an embodiment of the connection of each unit of the solar cell unit-equipped blind according to the present invention and the electrical wiring by the connecting component unit. In this example, six slats 110 equipped with solar cell units 120, length adjustment parts 140, and connection parts 130 are attached to the blind housing 600. An example of connecting external wiring between the connection parts 130 of each slat 110 is shown. The external wiring terminals 510 on the connection parts 130 of each slat 110 are shown as the right-side terminals and the left-side terminals in the figure. Between the connection parts 130 of each slat, the right-side terminals are connected to each other, and the left-side terminals are connected to each other to form an aggregated output terminal 610 to the outside. In this figure, the electrical connection between the connection parts 130 of each slat 110 is not connected adjacent to each other, but is connected skipping one (furthermore, skipping two or three as required), and is bundled at the aggregated output terminal 610. The reason is that the slat 110 is subject to bending stress on the wiring due to the frequent opening and closing operations of the blind and movement by wind force. Considering that if the connections are close to each other adjacent to each other, the bending of the wiring will be tight and it will be easy to deteriorate (conversely, it will be difficult to move), in order to relieve the bending, the wiring is not connected adjacent to each other. The wiring between the right-side terminals and the left-side terminals has the advantage of preventing misjudgment of the wiring by human visual inspection. Conversely, it is also possible to install either one of the right-side terminal and the left-side terminal (the right-side terminal in the figure, shown by the dotted line) on the back side.

[0029] FIG. 7 is a diagram showing an embodiment of the housing configuration of a blind equipped with a solar cell unit according to the present invention. 7-A is the basic configuration of the housing used in the previous explanation, and the slat 110 was passed through the fitting groove 123 in the longitudinal direction of the slat 110. This is the case where a plurality of solar cell units 120 are attached to one slat 110. When replacing the intermediate one, it is necessary to pull it out up to the target one. In the configurations of 7-B and 7-C, the housing 122 of the solar cell unit 120 includes a housing body 122A having a housing part for accommodating the slat 110 and an opening through which the slat 110 can be inserted and removed, and a housing lid body 122B serving as a lid for closing the opening. 7-B can open and close the housing lid body 122B at a right angle to the length direction of the slat 110 and in a direction parallel to the plate of the slat 110. 7-C can open and close the housing lid 122B at a right angle to the length direction of the slat 110 and at a right angle to the plate of the slat 110. In any case, loosen and remove the connecting means 124 of the adjacent solar cell units 120, and remove the housing lid 122B from the housing body 122A. Then, the slat 110 can be easily removed through the opening and replaced with another solar cell unit 120, which is convenient. In addition, the contact part between the housing body 122A and the housing lid 122B preferably has means such as screwing or, normally, not coming off under the contact pressure, but being able to be inserted and removed when pulled or pushed with a strong pressure. In the diagrams of 7-B and 7-C, in 7-B-1 and 7-C-1, the housing body 122A and the housing lid 122B are combined including the slat 110; in 7-B-2 and 7-C-2, there are sectional views at C-C and D-D respectively; in 7-B-3 and 7-C-3, there is the housing body 122A including the slat 110; in 7-B-4 and 7-C-4, the removed housing lid 122B is shown. Naturally, the opening is open and the slat 110 can be freely inserted and removed, or the slat 110 and the housing 122 can be freely attached and detached, and only the target solar cell unit 120 can be exchanged, etc.

Therefore, operations such as manufacturing, installation, removal, and replacement are facilitated, which is convenient for industrial use.
