DETAILED DESCRIPTION

[0047] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0048] In the description of the present invention, it should be understood that the terms "center", "length", "width", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "side" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0049] The embodiments of the present invention provide a photovoltaic panel structure, a photovoltaic tile and a photovoltaic tile assembly which are easy to install and can improve installation efficiency and waterproof performance.

[0050] Combine the following Figure 2-Figure 11 The technical solution provided by the present invention is described in more detail.

[0051] like Figure 2-Figure 6 As shown, a photovoltaic panel structure is provided in the present embodiment, including a photovoltaic panel, on which there is a mounting portion 5 and / or a receiving portion 4, wherein: one of the mounting portion 5 and the receiving portion 4 is provided with a negative terminal 3, and the other is provided with a positive terminal 2, and when the mounting portion 5 on one photovoltaic panel is inserted into and embedded in the receiving portion 4 on the other photovoltaic panel along the assembly direction, the positive terminal 2 can be inserted into the negative terminal 3 along the assembly direction or in the opposite direction of the assembly direction, and the two photovoltaic panels can be fixedly connected.

[0052] The above-mentioned photovoltaic panel structure can be applied to rooftop photovoltaic tiles or road photovoltaic panels. When laid on the roof or the road, the photovoltaic panels are usually arranged in an array. In each column (or row) of photovoltaic panels, the photovoltaic panels (edge ​​panels) located at both ends of each column (or row) only need to be connected to one photovoltaic panel, so only the mounting part 5 or the receiving part 4 can be set, or the mounting part 5 and the receiving part 4 can be set at the same time; the remaining photovoltaic panels (middle panels) need to be connected to two photovoltaic panels, so they need to be provided with the mounting part 5 and the receiving part 4 at the same time.

[0053] In the above-mentioned photovoltaic panel structure, the negative terminal 3 and the positive terminal 2 are respectively arranged on the mounting part 5 and the receiving part 4. The mounting part 5 on one photovoltaic panel is inserted into and embedded in the receiving part 4 on the other photovoltaic panel along the assembly direction, thereby realizing the fixed connection of the two photovoltaic panels and the electrical connection of the two photovoltaic panels by plugging the positive terminal 2 and the negative terminal 3, reducing the power loss of the lead wire and improving the installation efficiency; and the assembly direction of the positive terminal 2 is the same as or opposite to the assembly direction of the mounting part 5, which is easier to assemble and reduces the difficulty of installation.

[0054] Combination Figure 3 and Figure 4As shown, direction A along the arrow direction in the figure is the assembly direction of the mounting portion 5 inserted into the receiving portion 4, that is, the "assembly direction" is the direction in which the mounting portion 5 is inserted and embedded in the receiving portion 4. In the illustrated embodiment, a positive terminal 2 is provided on the mounting portion 5, so when the mounting portion 5 on one photovoltaic panel is inserted into and embedded in the receiving portion 4 on another photovoltaic panel along the assembly direction, the positive terminal 2 can be inserted into the negative terminal 3 along the assembly direction; alternatively, when the negative terminal 3 is provided on the mounting portion 5 (not shown in the figure), the positive terminal 2 is provided on the receiving portion 4, and when the mounting portion 5 on one photovoltaic panel is inserted into and embedded in the receiving portion 4 on another photovoltaic panel along the assembly direction, the positive terminal 2 is inserted into the negative terminal 3 in the opposite direction of the assembly direction.

[0055] The above two situations, i.e., the assembly direction of the installation part 5 inserted into the receiving part 4 and the assembly direction of the positive terminal 2 inserted into the negative terminal 3 are the same or opposite, which prevents the installation part 5 from being affected by the structures of the positive terminal 2 and the negative terminal 3 when being plugged into the receiving part 4, and facilitates the installation part 5 to be more smoothly embedded in the receiving part 4 to complete the assembly, and at the same time facilitates the positive terminal 2 to be more smoothly inserted into the negative terminal 3 to complete the electrical connection, and the two do not affect each other, and the assembly is convenient.

[0056] As an alternative embodiment, see Figure 2-Figure 6 As shown, the mounting portion 5 is a raised structure, and the receiving portion 4 is a groove structure, wherein: the positive terminal 2 is arranged on the raised structure and the two are raised in the same direction, and the negative terminal 3 is arranged in the groove structure and the two are recessed in the same direction, as shown in FIG. Figure 3 and Figure 4 As shown; or, the negative terminal 3 is arranged on the protruding structure, and the recessed direction of the negative terminal 3 is opposite to the protruding direction of the protruding structure, and the positive terminal 2 is arranged in the groove structure, and the protruding direction of the positive terminal 2 is opposite to the recessed direction of the groove structure (not shown in the figure).

[0057] Among them, the first embodiment is preferably adopted, which facilitates the synchronous insertion of the positive terminal 2 and the mounting portion 5 into the negative terminal 3 and the receiving portion 4. The positive terminal 2 and the protruding structure are both protruding in the same direction, so that when the mounting portion 5 on one photovoltaic panel is inserted and embedded in the receiving portion 4 on another photovoltaic panel along the assembly direction, the positive terminal 2 is inserted into the negative terminal 3 along the assembly direction, preventing the positive terminal 2 from affecting the plug-in installation of the protruding structure in the recessed structure.

[0058] In order to make the connection structure of the two photovoltaic panels more secure, as an optional implementation, see Figure 2-Figure 6The mounting portion 5 of the embodiment shown is a buckle structure, and the receiving portion 4 is a slot structure. The buckle structure is inserted into the slot structure along the assembly direction to buckle the two photovoltaic panels. The buckle structure as the mounting portion 5 is inserted into the slot structure as the receiving portion 4, and the two are buckled and connected, which can play a role of locking and fixing, preventing the mounting portion 5 from being separated from the receiving portion 4, and ensuring the stability of the connection structure between the two photovoltaic panels.

[0059] The specific structures of the buckle structure and the slot structure are not limited, such as Figure 3-Figure 5 , Figure 6 As shown, this embodiment provides two specific implementations of the buckle structure and the slot structure.

[0060] Embodiment 1:

[0061] See also Figure 6 As shown, the buckle structure as the mounting portion 5 in this embodiment includes a first clamping section 51 and a contraction section 52 connected to each other, the positive terminal 2 is located on the first clamping section 51, and the outer diameter of the first clamping section 51 is larger than the outer diameter of the contraction section 52; the receiving portion 4 includes a first receiving section 41 and a shrinking section 42 connected to each other, the negative terminal 3 is located in the first receiving section 41, and the inner diameter of the first receiving section 41 is larger than the inner diameter of the shrinking section 42; the first clamping section 51 is inserted into the first receiving section from the shrinking section 42 until it is completely embedded in the first receiving section 41, and the shrinking section 42 contacts and cooperates with the contraction section 52. The first clamping section 51 is completely embedded in the first receiving section 41, and the two are interference-fitted; and the matching structure of the locking section on the slot structure and the contraction section 52 on the buckle structure can further prevent the first clamping section 51 from escaping from the first receiving section 41.

[0062] In this embodiment, the outer contour of the first engaging section 51 is a combination of an arc shape and a straight line shape. Figure 6 As shown, both side portions of the first engaging section 51 are arc-shaped, and one end facing the other photovoltaic panel receiving portion 4 is straight; the inner side wall of the first receiving section 41 is an arc-shaped shape that matches the first engaging section 51, so that the first engaging section 51 can be smoothly inserted into the first receiving section 41 with the arc-shaped side as a guide.

[0063] Embodiment 2:

[0064] See also Figure 3-Figure 5As shown, in this embodiment, the snap-fit ​​structure as the mounting portion 5 includes a first snap-fit ​​section 51, a contraction section 52 and a second snap-fit ​​section 53 connected to each other, the positive terminal 2 is located on the first snap-fit ​​section 51, the second snap-fit ​​section 53 is connected to the first snap-fit ​​section 51 through the contraction section 52, and the outer diameters of the first snap-fit ​​section 51 and the second snap-fit ​​section 53 are both larger than the outer diameter of the contraction section 52; the receiving portion 4 as a slot structure includes a first receiving section 41, a shrinkage section 42 and a second receiving section 43 connected to each other, the negative terminal 3 is located in the first receiving section 41, the second receiving section 43 is connected to the first receiving section 41 through the contraction section 42, and the inner diameters of the first receiving section 41 and the second receiving section 43 are both larger than the inner diameter of the contraction section 42; when the first snap-fit ​​section 51 is fully embedded in the first receiving section 41, the contraction section 42 is in contact with the contraction section 52 and the second snap-fit ​​section 53 is fully embedded in the second receiving section 43.

[0065] The snap-fit ​​structure in this embodiment includes a first snap-fit ​​section 51 and a second snap-fit ​​section 53 connected by a contraction section 52. Similarly, the slot structure includes a first receiving section 41 and a second receiving section 43 connected by a necking section 42. The first snap-fit ​​section 51 is interference fit with the first receiving section 41, the contraction section 52 is abutted against the necking section 42, and the second snap-fit ​​section 53 is interference fit with the second receiving section 43, which can further improve the tightness and stability of the snap connection structure and prevent the mounting portion 5 from loosening from the receiving portion 4.

[0066] Considering the stability of the connection structure, the connection structure in the second embodiment is preferably used. In order to facilitate the insertion of the buckle structure into the slot structure, the outer contours of the first engaging section 51 and / or the second engaging section 53 are both arc-shaped, the inner contour of the first receiving section is adapted to the outer contour of the first engaging section 51, and the inner contour of the second receiving section 43 is adapted to the outer contour of the second engaging section 53. Figure 3-Figure 5 As shown, in this embodiment, the outer contours of the first engaging section 51 and the second engaging section 53 are both arc-shaped.

[0067] The outer contours of the first engaging section 51 and the second engaging section 53 are both arc-shaped, which can play a guiding role, so that the first engaging section 51 and the second engaging section 53 can be smoothly inserted into the first receiving section 41 and the second receiving section 43 respectively, so as to facilitate assembly.

[0068] To ensure a secure connection, see Figure 5 The outer diameter d1 of the first engaging section 51 on the photovoltaic panel is slightly larger than the inner diameter d2 of the first receiving section 41, so that the two are interference fit; the outer diameter d1 of the first engaging portion is slightly larger than the inner diameter d3 of the locking section, so as to prevent the first engaging section 51 from escaping from the shrinking section 42; the outer diameter r1 of the second engaging section 53 is approximately equal to or slightly larger than the inner diameter r2 of the second receiving section ( Figure 5 ).

[0069] As an alternative embodiment, see Figure 2 , Fig. 9 When the photovoltaic panel has both the mounting portion 5 and the receiving portion 4, the mounting portion 5 and the receiving portion 4 are located at opposite sides of the photovoltaic panel. This structure can facilitate the connection of multiple photovoltaic panels into a column (or a row), facilitate the arrangement of photovoltaic panels in an array, and facilitate the neat installation of photovoltaic panels on roofs or roads.

[0070] As an alternative embodiment, see Figure 7 and Figure 8 As shown, the photovoltaic panel of this embodiment includes a first board body layer 101, an encapsulation film layer 104, a battery cell 102 and a second board body layer 103, wherein: the encapsulation film layer 104 is located between the first board body layer 101 and the second board body layer 103 and connects the two, the battery cell 102 is wrapped in the encapsulation film layer 104, and the battery cell 102 is electrically connected to the negative terminal 3 and the positive terminal 2 (not shown in the figure), wherein the battery cell is a solar cell.

[0071] The encapsulation film layer 104 is heat-melted and seals the solar cell through a high-temperature vacuum process. The first board layer 101 is the front layer facing the sunlight, and is mainly made of transparent glass or other transparent and high-temperature resistant materials; the second board layer 103 is the back layer facing away from the sunlight, and is mainly made of non-transparent ceramic or metal materials.

[0072] The present invention also provides a photovoltaic tile 1, see Figure 9-11 As shown, the photovoltaic tile 1 of this embodiment has the photovoltaic panel structure, and thus has the advantages of high installation efficiency, good waterproofness and weather resistance.

[0073] The present invention also provides a photovoltaic tile assembly, see Figure 9-11 As shown, it includes the above-mentioned photovoltaic tile 1, and more than two tiles are arranged at the installation position, and at least two adjacent tiles are fixedly connected through the matching structure of the installation part 5 and the receiving part 4, and are electrically connected through the positive terminal 2 and the negative terminal 3 that are plugged in each other.

[0074] The photovoltaic tile assembly of this embodiment has the above-mentioned photovoltaic panel structure, and the tiles are fixed to each other through the mounting portion 5 and the receiving portion 4, and the positive terminal 2 and the negative terminal 3 are plugged in at the same time, so it also has high installation efficiency; the positive terminal 2 and the negative terminal 3 are wrapped in the matching structure of the mounting portion 5 and the receiving portion 4, and are difficult to contact with external water vapor, and have good waterproof and weather resistance, which can increase the service life of the tiles.

[0075] As an alternative embodiment, see Fig. 9 and Fig.10As shown, at the location to be installed, there are two or more groups of tiles on the roof, wherein: in the same group of tiles, any two adjacent tiles are fixedly connected by plugging and fixing the mounting portion 5 and the receiving portion 4; in different groups of tiles, any two adjacent tiles are fixedly connected by the sealing adhesive portion 9. The same group of tiles refers to tiles in the same column or row. The above structure realizes the connection between tiles in two different directions, which is convenient for the tiles to be arranged in an array.

[0076] In the prior art, tiles are usually overlapped to achieve connection between adjacent tiles of different groups. This structure results in more tiles, waste of materials, and high cost. The sealing adhesive portion 9 of this embodiment can be a sealing structural adhesive. The sealing adhesive portion 9 is used to achieve connection between tiles of different groups, the connection structure is stable, and waste of tile materials is prevented, thereby reducing the laying cost.

[0077] As an alternative embodiment, see Fig. 9 As shown, the photovoltaic tile assembly of this embodiment also includes an electrical system bus 8; each group of tiles includes a top tile 13 and a bottom tile 12, see Fig. 9 There is also a middle tile 11 between the top tile 13 and the bottom tile 12, and the middle tile 11 is provided with a mounting portion 5 and a receiving portion 4; the top tile 13 and the bottom tile 12 are respectively located at the two ends of each group of tiles, and one of the top tile 13 and the bottom tile 12 has a positive electrode connection, which is electrically connected to the electrical system bus 8, and the other has a negative electrode connection, which is electrically connected to the electrical system bus 8. The above structure allows each group of tiles to be connected in series to the electrical system bus 8 while being fixedly connected.

[0078] The top tile 13 is a tile located on the roof in each group, which may or may not be provided with a photovoltaic panel (usually not provided with a photovoltaic panel); the bottom tile 12 is a tile located at the eaves in each group, which is usually provided with a photovoltaic panel. The top tile 13 and the bottom tile 12 are edge tiles, and both of them can be provided with a mounting portion 5 and a receiving portion. Since the top tile 13 and the bottom tile 12 only need to be connected to one tile, the top tile 13 and the bottom tile 12 can also be provided with only a mounting portion 5 or a receiving portion 4 connected to another tile.

[0079] As an alternative embodiment, see Fig. 9 and Fig.11 As shown, the photovoltaic tile assembly also includes purlins 7 and tile hanging bars 6, wherein: the purlins 7 are fixed on the location to be installed (roof), the purlins 7 are arranged at intervals, and each tile hanging bar 6 is fixed on at least two purlins 7 to form a frame structure at the location to be installed; the tiles are fixed on the tile hanging bars 6 accordingly.

[0080] During the specific installation, the two tiles can be plugged into place through the installation part 5 and the receiving part 4, and at the same time, the positive terminal 2 and the negative terminal 3 are plugged into place, see Figure 3 and Figure 4 Each set of photovoltaic tiles 1 (including a top tile 13, a number of middle tiles 11, and a bottom tile 12) is assembled on the tile hanging strip 6 and then fixed to the tile hanging strip 6 with screws or other locking parts ( Fig.11 ).
