Description

[Technical field]

[0001] The present invention relates to a photoelectric building block comprising photovoltaic panels connected to a high strength, high durability rigid support, typically a ceramic or mortar support, suitable for architectural integration, although other materials such as plastics are also contemplated.

[0002] A photovoltaic panel is understood as a device in the form of a flat panel, which is capable of generating electrical energy upon receiving light directly as a result of the photoelectric effect, for example a photovoltaic panel, or of generating light upon receiving electrical energy, for example a light panel or screen. [Background technology]

[0003] Photovoltaic building blocks are known, said blocks comprising photovoltaic panels fixed on rigid supports, made of non-metallic materials and therefore easily integrable into buildings made with techniques common in the field, the rigid supports being typically ceramic, mortar or stone panels, intended as roof tiles, or facade cladding, or even bricks.

[0004] For example, document CN209556279U describes a ceramic brick with a central recess in which a photovoltaic panel is housed and held by adhesive. Due to its geometric shape, the ceramic brick described in this document cannot be manufactured by an extrusion process, which increases the manufacturing costs and slows down the production. Furthermore, the fixing of the photovoltaic panel by adhesive interferes or prevents the maintenance or replacement of the photovoltaic panel, if necessary, and also prevents future reuse or recycling of the assembly.

[0005] Document US2014007528A1 also describes a building block comprising a rigid support in the form of a mortar block, to which a photovoltaic panel is attached via an intermediate metal structure, in this case formed by folded sheet metal. Both the manufacture of the intermediate structure and its fixing to the rigid mortar support are not optimized for rapid and cost-effective mass production.

[0006] Document US5112408A describes a building block formed by a rigid support having a recessed channel defined between two opposing parallel grooved guides into which the two side edges of the photovoltaic panel are inserted. This document describes the inclusion of a toothed profile on the inside of the grooved guide, on the opposing face, complementary to the toothed profile provided on the side edges of the photovoltaic panel. The toothed profile is configured to allow the sliding insertion of the photovoltaic panel from the open end towards the closed end of the rigid support in a direction parallel to the grooved guide, and to hold the solar panel inside the recessed channel. A rigid support with a geometry defined in this document requires complex moulds in its manufacture or machining, which increases the manufacturing costs. Moreover, the toothed profile proposed in this document prevents the photovoltaic panel from sliding out in a direction parallel to the grooved guides, but does not prevent the photovoltaic panel from vibrating in a direction perpendicular to the photovoltaic panel, for example due to wind.

[0007] Document CN113872502A also describes a building block formed by a rigid support having a recessed channel defined between two opposing parallel grooved guides into which the two side edges of a photovoltaic panel are inserted. However, this document does not describe any holding device to prevent the photovoltaic panel from dislodging or vibrating. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention solves these and other problems. [Means for solving the problem]

[0009] <Brief Description of the Invention> The present invention relates to an optoelectronic building block.

[0010] A building block is understood as an element suitable for architectural integration in a building, typically a part constituting a wall, a cladding, a lattice structure, etc.

[0011] As is already known, the proposed photovoltaic building blocks are: a rigid support made from a single piece of extrudable non-metallic material, the rigid support comprising a front portion having a first connecting configuration and a rear portion; at least one photovoltaic panel having a second coupling arrangement attached to the first coupling arrangement, said photovoltaic panel covering at least a portion of a front part of said rigid support; the first coupling arrangement comprises a sunken channel between two opposing parallel grooved guides formed on a front portion of the rigid support, the two opposing parallel grooved guides defining a narrowing of an opening of the sunken channel, each grooved guide including a lower surface facing a bottom of the sunken channel; a second coupling arrangement is inserted into the recessed channel and has opposing coupling ends inserted into two opposing grooved guides, the separation between the opposing coupling ends being greater than the opening of the recessed channel; The photovoltaic building block further comprises a retainer device that holds the photovoltaic panel against a rigid support and prevents sliding of the second coupling arrangement relative to the first coupling arrangement.

[0012] A rigid support made of an extrudable non-metallic material is understood as a plate made of a material that can be formed by an extrusion process. Non-metallic materials that are typically formed by extrusion are, for example, ceramic, mortar and plastic materials.

[0013] Metallic materials present corrosion problems, are electrically conductive and cause high environmental impacts for their manufacture. Furthermore, they present other challenges that hinder architectural integration, for example, they do not adhere easily to common building materials, for example by mortar, and require expensive mechanical fastening elements. Another problem is that they have a thermal expansion much higher than that of other materials commonly used in construction, such as ceramics, concrete and mortar, and therefore for their integration special attachments are required that absorb said expansion difference.

[0014] All these problems are avoided by using a rigid support made of an extrudable non-metallic material, preferably a ceramic, mortar, concrete material, or a plastic material that does not have an expansion too different from common building materials.

[0015] The rigid support has two major surfaces, one of which is the front of the rigid support, which is arranged to be oriented towards the sun, and the other major surface opposite the front is the rear. The rigid support can have other surfaces around its periphery, for example two end portions and two sides.

[0016] The photovoltaic panel covers at least a portion of the front of the rigid support, is exposed to sunlight, and is visible to (or can be seen by) a potential user.

[0017] A photovoltaic panel is understood as a device in the form of a flat panel, which is capable of generating electrical energy upon receiving light directly as a result of the photovoltaic effect, for example a photovoltaic panel, or of generating light upon receiving electrical energy, for example a light panel or screen.

[0018] For example, a photovoltaic panel can be a rigid or flexible panel made of silicon, perovskite, or another material that produces electrical energy under the direct incidence of sunlight as a result of the photovoltaic effect.

[0019] For example, the light panel may be an LED (light emitting diode) panel, an OLED (organic light emitting diode) panel, or another equivalent technology that emits light for illumination, signaling, or other uses.

[0020] For example, the screen may be an AMOLED (Active Matrix Organic Light Emitting Diode) screen, an LCD (Liquid Crystal Display) screen with LED backlighting, or another equivalent technology.

[0021] According to the above, the front portion of the rigid support has two opposing parallel grooved guides and a recessed channel defined between said grooved guides.

[0022] The edges of the two parallel guides determine the constriction of the opening of the recessed channel, i.e. the distance between said edges is smaller than the maximum width of the recessed channel including the inner width of the two grooved guides.

[0023] The constriction determines which portion of the wall defining each grooved guide faces the bottom of the recessed channel and constitutes the lower surface of the grooved guide.

[0024] An element constituting a second coupling arrangement, the element having a width greater than the width of the opening of the recessed channel, received within the recessed channel and with its opposing coupling ends inserted into the grooved guide, is fixed to the rigid support and constitutes the second coupling arrangement.

[0025] In particular, when the rigid support is obtained by an extrusion process, and optionally by a subsequent firing process, such as when the rigid support is made from a ceramic material, the second connecting arrangement inserted into the recessed channel may slide along the grooved guide or vibrate therein, especially considering that the rigid support may have manufacturing tolerances larger than those of the photovoltaic panel. Said different manufacturing tolerances between the rigid support and the photovoltaic panel prevent a snug and play-free insertion of the first and second connecting arrangements.

[0026] It is proposed to include a retaining device to prevent said sliding and vibration.

[0027] In a manner not yet known, the present invention further proposes: the rigid support has a cross section perpendicular to the two grooved guides and constant along its entire length, defining a geometry suitable for producing it by extrusion; The retaining device exerts a pushing force (or thrust) urging the opposing coupling ends of the second coupling arrangement against the undersides of the two grooved guides, moving them away from the bottom of the recessed channel.

[0028] Due to the constant cross-section of the rigid support, which allows for cost-effective manufacturing by extrusion, the recessed channel is accessible through the end of the rigid support where the end of the grooved guide is open and accessible, allowing insertion into the second coupling arrangement by longitudinal sliding of the grooved guide, and the recessed channel is accessible through an opening defined between two parallel edges of the grooved guide.

[0029] The proposed holding device holds the photovoltaic panel against the rigid support as a result of pressing the opposing connecting ends against the undersides of two grooved guides facing the bottom of the recessed channel, preventing sliding of the second connecting arrangement relative to the first connecting arrangement and preventing its vibrations, and at the same time allowing the rigid support to be manufactured by extrusion, allowing a very cost-effective continuous production.

[0030] The pressure of the opposing coupling ends against the undersides of the grooved guides prevents sliding of the second coupling arrangement along the two grooved guides and prevents sliding of the photovoltaic panel which is fixed to the rigid support via said second coupling arrangement.

[0031] Preferably, a retention device, such as a wedge, is received between the photovoltaic panel and the bottom of the recessed channel to generate the aforementioned pushing force on the opposing linkage ends against the lower surfaces of the two grooved guides. In this manner, the retention device inserted between the photovoltaic panel and the bottom of the recessed channel generates a pushing force to move the photovoltaic panel and its corresponding opposing linkage ends away from the recessed channel.

[0032] Optionally, at least one of the retaining device, the photovoltaic panel, or the opposing mating ends thereof can be at least partially elastically deformed to facilitate insertion of the retaining device, the elastic deformation occurring during said insertion urging the photovoltaic panel outwardly against the recessed channel.

[0033] For example, the holding device may include two runners disposed between the photovoltaic panel and the bottom of the recessed channel, which may slide from the center of the recessed channel toward two grooved guides.

[0034] According to another embodiment, the bottom of the recessed channel may be concave, defining a narrowing of the distance between the photovoltaic panel and the bottom of the recessed channel towards the two grooved guides. In this way, the wedge effect increases as the runner slides towards the grooved guides.

[0035] Each runner may optionally include guide flanges supported on the ends of the rigid support and / or seating flanges on which the lateral edges of a photovoltaic panel disposed between the grooved guides rest, these flanges making it possible to fix the position of the runner relative to the rigid support and / or the position of the photovoltaic panel relative to the runner.

[0036] According to another embodiment, the retaining device may comprise one or more wedges that are inserted between the photovoltaic panel and the bottom of the recessed channel.

[0037] The rigid support may, for example, include through holes parallel to the grooved guide to reduce its weight. In such a case, each wedge may include a fastener, or a fastener with a toothed or barbed configuration on its edge, which fits snugly into one of said through holes to fix its position.

[0038] It is also proposed that each wedge may include a seating flange against which a lateral edge of a photovoltaic panel disposed between the grooved guides rests.

[0039] According to another alternative embodiment, the holding device is made of convexities and / or protuberances protruding from the bottom of the recessed channel and is configured to hold the flexible photovoltaic panel in a bent position between the lower surface of the grooved guide and the convexities and / or ridges of the recessed channel. According to this embodiment, the photovoltaic panel has to be bent for its sliding insertion from the end of the rigid support into the recessed channel and remains bent while sliding to its final position. The actual elastic deformation of the photovoltaic panel then presses its central region against the convexities and / or protuberances protruding from the bottom of the recessed channel and at the same time presses the opposite connecting ends against the lower surfaces of the two grooved guides. Preferably, the convexities and / or protuberances are linearly interposed between the lower surfaces of the two grooved guides and prevent the photovoltaic panel from becoming flat.

[0040] According to another embodiment, the holding device is made up of a photovoltaic panel, which is flexible and held between the grooved guides in a curved position, and a bottom of a recessed channel, which is concave and has a width measured in a straight line between the opposing inner parts of both grooved guides, which is equal to or greater than the length between the two opposing connecting ends measured in a straight line when the photovoltaic panel is held in the curved position and less than said length between the opposing connecting ends measured in a straight line when the photovoltaic panel is not connected and is flat, the curvature of the photovoltaic panel causing the above-mentioned pushing force on the opposing connecting ends against the lower faces of the two grooved guides. According to this embodiment, the photovoltaic panel is held inside the recessed channel in a curved position and is therefore subjected to an elastic expansion force in order to try to recover its flat position. Said elastic force will push the photovoltaic panel, moving it away from the bottom of the recessed channel and holding it inside the grooved guides, so that in this case it is the photovoltaic panel itself that acts as a holding device.

[0041] For example, references to geometric positions such as parallel, perpendicular, tangential, etc. will be understood to allow for deviations of up to ±5° from the theoretical positions defined by the nomenclature.

[0042] Other features of the present invention will become apparent from the detailed description of the embodiments below. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0044] The accompanying drawings illustrate non-limiting exemplary embodiments of the present invention.

[0045] According to one embodiment, the present invention relates to a photovoltaic building block suitable for architectural integration.

[0046] The photovoltaic building block comprises a rigid support (1) made of a single piece of extrudable non-metallic material. Typically, said rigid support (1) is a ceramic or mortar block, e.g. a brick, or a flat ceramic or mortar panel, e.g. a tile. Optionally, said rigid support (1) can be made of plastic.

[0047] The rigid support (1) comprises a front portion having a first connecting arrangement (10) and a rear portion.

[0048] The photovoltaic building block also includes at least one photovoltaic panel (2) that includes a second connecting arrangement (20).

[0049] A second connecting arrangement (20) is attached to the first connecting arrangement (10) and secures the photovoltaic panel (2) to the rigid support (1).

[0050] The photovoltaic panel (2) covers at least a portion of the front of the rigid support (1).

[0051] The first coupling arrangement (10) consists of a recessed channel (11) formed in the front part of the rigid support (1) between two opposing parallel grooved guides (12) which define a constriction at the opening of the recessed channel (11), each grooved guide (12) including a lower surface (13) facing the bottom of the recessed channel (11).

[0052] According to one embodiment, the lower surfaces (13) of the two grooved guides (12) may be coplanar with each other or may be inclined towards the opening of the recessed channel (11).

[0053] The rigid support (1) has a cross section perpendicular to the two grooved guides (12) and constant along its entire length, defining a geometry suitable for manufacturing it by extrusion. This geometry, together with a material selected to be extrudable, allows said rigid support to be manufactured by extrusion, thereby achieving a rapid, efficient and very cost-effective continuous manufacture, said rigid support including the two grooved guides (12) without the need for subsequent manufacturing operations. The rigid support is therefore preferably manufactured by extrusion.

[0054] A second connecting arrangement (20) of the photovoltaic panel (2) is inserted into the recessed channel (11) and has opposing connecting ends (21) that are inserted into two opposing grooved guides (12), with the separation between the opposing connecting ends (21) being greater than the opening of the recessed channel (11).

[0055] According to a preferred embodiment shown in figures 1 to 6, the second connecting arrangement (20) consists of the photovoltaic panel (2) itself, which is inserted into a recessed channel (11). The photovoltaic panel (2) has two parallel side edges, which are inserted into two grooved guides (12), and which constitute opposing connecting ends (21).

[0056] According to a preferred embodiment, the side edges of the photovoltaic panel (2), or both the side edges and the lateral edges of the photovoltaic panel (2), include a protective profile connected along its length, typically a U-shaped profile, preventing direct contact between the photovoltaic panel (2) and the rigid support (1).

[0057] The photovoltaic panel (2) further comprises at least two conductive cables connected to two opposing edges of the photovoltaic panel (2), at least a portion of the two conductive cables extending in the longitudinal direction of the grooved guide over the rear of the photovoltaic panel.

[0058] For example, two conductive cables can be connected to two side edges of a photovoltaic panel inserted into two grooved guides (12). Thus, the conductive cables are at least partially housed inside the grooved guides (12) from at least the connection points with the photovoltaic panel (2) to the ends of the rigid support (1).

[0059] According to another embodiment, the conductive cable is connected to two lateral edges of the photovoltaic panel (2) located between grooved guides (12), one of which crosses longitudinally at the rear of the photovoltaic panel, for example along a central area of ​​the photovoltaic panel contained between the two side edges.

[0060] According to one embodiment, the conductive cable is placed at the rear of the photovoltaic panel (2) and the bottom of the recessed channel (11) includes a longitudinal recess that allows said conductive cable to be accommodated without being pressed against the bottom of the recessed channel (11).

[0061] Alternatively, the second coupling arrangement (20) may include one or more flanges adhered to the rear of the photovoltaic panel (2), as shown in FIG.

[0062] According to the illustrated embodiment, one or more flanges are inserted into one of the grooved guides (12) and a side edge of the photovoltaic panel (2) is inserted into the other grooved guide (12), and the assembly of the one or more flanges and the side edge of the photovoltaic panel forms opposing mating ends (21).

[0063] Alternatively, according to an embodiment not shown, said flange or flanges are inserted simultaneously into both grooved guides (12), said flange or flanges forming opposing connecting ends (21).

[0064] The photovoltaic building block further comprises a retaining device (30) which applies a pushing force (or thrust) to the opposing connecting ends (21) of the second connecting arrangement (20) moving them away from the bottom of the recessed channel (11) and pressing them against the undersides (13) of the two grooved guides (12), holding the photovoltaic panel (2) against the rigid support (1) and preventing sliding of the second connecting arrangement (20) relative to the first connecting arrangement (10).

[0065] According to one embodiment shown in Figures 1-4, the holding device (30) comprises two runners arranged between the photovoltaic panel (2) and the bottom of the recessed channel (11), which can slide from the center of the recessed channel (11) towards two grooved guides (12) and act as wedges between the photovoltaic panel (2) and the bottom of the recessed channel (11).

[0066] Each runner may further include a guide flange (31) supported on an end of the rigid support (1) and / or a seating flange (32) on which the lateral edge of the photovoltaic panel (2) positioned between the grooved guides (12) rests.

[0067] Optionally, it is contemplated that the bottom of the recessed channel (11) is concave, as shown in FIG. 3, and / or that the photovoltaic panel (2) is flexible, as shown in FIG.

[0068] Any of these alternatives would allow the runner to slide towards the end, increasing the pressure of the opposing connecting end (21) against the lower surface (13).

[0069] Another additional or alternative embodiment, not shown, is to include a compressible element disposed between the opposing coupling ends (21) and the underside (13) of the grooved guide (12).

[0070] Another embodiment of the retaining device (30) shown in FIG. 5 comprises one or more elastically compressible wedges that are inserted between the photovoltaic panel (2) and the bottom of the recessed channel (11), said wedges constituting the retaining device (30).

[0071] The rigid support (1) may include through holes parallel to the grooved guide (12), which may also be obtained by an extrusion process.

[0072] In such a case, each wedge may include a fastener (33) that fits snugly into one of the through holes to fix its position. The fastener (33) may have a toothed or barbed configuration on its edge that contacts the inner surface of the through hole to ensure proper fixation, and may be of simple, low-cost construction formed by stamped and bent metal sheet.

[0073] Each wedge may also include a seating flange (32) against which a lateral edge of a photovoltaic panel (2) positioned between the grooved guides (12) rests.

[0074] According to another embodiment shown in Fig. 6, the bottom of the recessed channel (11) is convex and / or includes a protruding protrusion. In such a case, the photovoltaic panel (2) is flexible and is held in a curved position between the lower surface (13) of the grooved guide (12) and the convex bottom and / or the raised portion of the recessed channel (11). The assembly of the flexible photovoltaic panel (2) and the convex bottom and / or the bottom with the protrusion constitutes the holding device (30).

[0075] According to another alternative embodiment, the photovoltaic panel (2) is flexible and is held between the grooved guides (12) in a curved position. The bottom of the recessed channel (11) is concave and the width of the recessed channel (11) measured in a straight line between the opposing inner portions of both grooved guides (12) is less than the length of the photovoltaic panel (2) measured in a straight line between the two opposing connecting ends when the panel is flat and is greater than or equal to the length of the photovoltaic panel (2) measured in a straight line between the two opposing connecting ends when the photovoltaic panel is held in the curved position. The assembly of the flexible photovoltaic panel (2) and the concave bottom constitutes the holding device (30).

[0076] The curved photovoltaic panel (2) attempts to recover its horizontal position by elastic bending, but the maximum width of the recessed channel, measured in a straight line between the opposing bottoms of the two grooved guides (12), prevents the photovoltaic panel from recovering said horizontal position with the panel held in place.

[0077] According to one embodiment, the photovoltaic panel (2) is a photovoltaic generator panel, or a light-emitting panel, or a moving image-emitting screen.

[0078] It is also proposed that the photovoltaic panel (2) may for example be cantilevered (or fixed at one end only) from a recessed channel (11) at its open end.

[0079] According to one embodiment shown in FIG. 7, at least a portion of the front of the rigid support (1), including at least a portion of the recessed channel (11), and the rear of the rigid support are not parallel, and the photovoltaic panel is tilted relative to the rear to improve its solar exposure.

[0080] Thus, at least a portion of the rear and front portions are not parallel, increasing the visibility of the solar energy capture or photovoltaic panels.
