[0047] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0048] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0049] See attached Figure 1-8 The embodiment of the utility model discloses a photovoltaic flat tile 100, the photovoltaic flat tile 100 includes a photovoltaic module 101, wherein the photovoltaic module 101 includes a front glass, a back glass and a battery 1011 encapsulated between the front glass and the back glass, and the photovoltaic module 101 can adopt a double glass structure or a single glass structure. The photovoltaic flat tile 100 also includes a frame for supporting the photovoltaic module 101, wherein the frame includes an upper frame 102, a lower frame 103, a first side frame 104 and a second side frame 105. In actual setting, the first side frame 104 of the photovoltaic flat tile 100 in this embodiment is provided with a first overlap portion, and the side portion of the second side frame 105 is provided with a second overlap portion, the first overlap portion is provided with a first overlap interface 1042, and the second overlap portion is provided with a second overlap interface 1052, and the opening directions of the first overlap interface 1042 and the second overlap interface 1052 are opposite. The first overlapping interface 1042 and the second overlapping interface 1052 in the present embodiment are symmetrical in structure, and the first overlapping portion and the second overlapping portion are overlapped with each other through the first overlapping interface 1042 and the second overlapping interface 1052. By arranging the first overlapping interfaces 1042 and the second overlapping interfaces 1052 with opposite openings on the opposite sides of the photovoltaic component 101, during laying, the first side frame 104 of one photovoltaic plane tile 100 and the second side frame 105 of the other photovoltaic plane tile 100 are opposite to each other, and can overlap with each other through the first overlapping interfaces 1042 and the second overlapping interfaces 1052 with opposite openings, so as to realize the connection of two adjacent photovoltaic plane tiles 100, and the overlap is realized through the structure of the photovoltaic plane tile 100 itself, without the need for additional overlapping components, thereby reducing the types of components when laying the photovoltaic plane tile 100, making the overlap more convenient and the integrity more compact, and reducing the assembly and matching relationship with separate overlapping components, thereby reducing the installation accuracy and the material cost.

[0050] The top surface of the frame of the lower frame of one embodiment of the present application is lower than the front surface of the photovoltaic module. When installing, the lower frame is installed at a low position. By setting a mounting structure without an A surface on the lower frame 103, when in use, rainwater, dust or impurities falling on the front of the photovoltaic module 101 will be discharged from the lower frame 103 along the front of the photovoltaic module 101 under the action of its own gravity, thereby preventing rainwater, dust or impurities from accumulating on the front of the photovoltaic module 101 and affecting the power generation efficiency of the photovoltaic module 101. The upper frame, the first side frame and the second side frame of the utility model can be set as a structure with an A surface. Specifically, a first mounting groove 1041 is provided on the first side frame 104, a second mounting groove 1051 is provided on the second side frame 105, a third mounting groove 1022 is provided on the upper frame 102, and the lower frame 103 is provided with a support portion 1031 for supporting the lower side of the photovoltaic module 101. The top surface of the lower frame 103 is lower than the front surface of the photovoltaic module 101. The upper side edge of the photovoltaic component 101 is installed in the third installation groove 1022 of the upper frame, the left side edge is inserted in the first installation groove 1041 of the first side frame, and the right side edge is inserted in the second installation groove 1051. In addition, the top surface of the corresponding frame is higher than the front surface of the photovoltaic component 101, realizing an installation structure with an A-side. The structure with A-side frames on three sides ensures the overall load capacity of the photovoltaic flat tile 100, thereby improving the strength of the photovoltaic flat tile 100.

[0051] Key reference Figure 2 , 3.1 , 3.2, 4.1, 4.2, 5.1, 5.2 and Figure 6.1 , 6.2 For the convenience of assembly and use, during the design, the slot widths of the third mounting slot 1022, the first mounting slot 1041, and the second mounting slot 1051 are larger than the corresponding side thickness of the photovoltaic module 101, and the difference between the slot width D and the corresponding side thickness d of the photovoltaic module 101 is 0-1.5 mm, which facilitates the side of the photovoltaic module 101 to be inserted into the mounting slot, and the distance a between the top surface of the lower frame 103 and the front surface of the photovoltaic module 101 is 1-5 mm.

[0052] Reference Figure 3.1 , 3.2, 9, 10, 11, 15, the utility model includes a hanging plate 1021 extending from the bottom plate of the upper frame 102 to the bottom of the photovoltaic module 101, and a hanging cavity cooperating with the hanging part 202 is formed between the hanging plate 1021 and the back of the photovoltaic module 101 and the side wall of the upper frame 102, and one end of the hanging part 202 is inserted into the hanging cavity. When installing the photovoltaic flat tile 100, it is only necessary to insert the hanging part 202 into the hanging cavity. The hanging cavity is a large space distributed along the direction of the upper frame 102, which is convenient for the insertion of the hanging part 202. The photovoltaic flat tile 100 will be stably hung on the installation hanger 200 through the hanging cavity under the action of its own gravity. Of course, in actual installation, in order to ensure the stability of the installation, each photovoltaic flat tile 100 can be provided with multiple installation hangers 200 accordingly. The multiple installation hangers 200 are distributed at intervals along the length direction of the photovoltaic flat tile 100, forming multi-point support for the photovoltaic flat tile 100, and improving the stability of the installation of the photovoltaic flat tile 100. Of course, in order to ensure the stability of the installation, the width L of the hanging plate 1021 is set to 5-15cm. Since the width of the matching part between the hanging plate 1021 and the hanging part 202 directly affects the installation strength and stability of the photovoltaic flat tile 100, the longer the width of the hanging plate 1021 and the hanging part 202, the higher the installation strength and stability of the photovoltaic flat tile 100. In actual settings, the width L of the hanging plate 1021 is preferably 10-15cm, wherein the width of the hanging part 202 can be adaptively selected according to the width of the hanging plate 1021, and the width of the hanging part 202 is generally set to be slightly larger than the width of the hanging plate 1021.

[0053] See attached Figure 7 The frame in this embodiment also includes a corner code connector 106, and the upper frame 102, the lower frame 103, the first side frame 104 and the second side frame 105 are respectively provided with a corner code groove 109 matched with the corner code connector 106, and the corner code connector 106 connects two adjacent frames through the corner code groove 109. In this way, the first side frame 104, the second side frame 105, the upper frame 102, and the lower frame 103 are connected by the corner code connector 106 to form a frame structure, so that the integrity is better. In order to better connect the adjacent upper frame 102 and the first side frame 104, the upper frame 102 and the second side frame 105, and the lower frame 103 and the first side frame 104, the lower frame 103 and the second side frame 105, the chamfered surface 108 can be respectively provided at the corner connection parts of the upper frame 102, the lower frame 103, the first side frame 104 and the second side frame 105, so as to facilitate the corner combination between the frames.

[0054] See attached Figure 1 , 8The front of the photovoltaic flat tile 100 of the utility model is provided with a water retaining strip. The water retaining strip is pasted on the front of the photovoltaic module 101. When it is set, the position of the water retaining strip can be set near the lower frame 103 or the upper frame 102 to prevent rainwater from flowing back along the joint surface of the upper and lower overlapping photovoltaic flat tiles 100. The water retaining strip 107 is a highly weather-resistant polymer material strip, which can be a semi-circular rubber strip made of EPDM rubber, with a hardness of preferably 30 to 50 HB. Its bottom edge is pasted on the upper surface of the photovoltaic module 101, the bottom edge width C is preferably 5 to 10 mm, and the height H is preferably 5 to 15 mm. The length range of the water retaining strip does not exceed the first side frame 104 and the second side frame 105.

[0055] The first overlapped portion of the present application includes a first overlapped bottom plate 1044 and a first overlapped vertical plate 1045. The first overlapped bottom plate 1044 and the first overlapped vertical plate 1045 form a first overlapped interface 1042 with the side wall of the frame. The overlapped portion on the second side frame 105 is a second overlapped portion. The second overlapped portion includes a second overlapped bottom plate 1054 and a second overlapped vertical plate 1055. The second overlapped bottom plate 1054 and the second overlapped vertical plate 1055 form a second overlapped interface 1052 with the side wall of the frame. Fig.13 , by setting the first overlapping portion on the first side frame 104 of the photovoltaic plane tile 100 and the second overlapping portion on the second side frame 105 of the photovoltaic plane tile 100, when installing the photovoltaic plane tile 100, the first side frame 104 and the second side frame 105 of the adjacent photovoltaic plane tile 100 are connected by the first overlapping portion and the second overlapping portion, and the overlapping structure is directly set on the frame of the photovoltaic plane tile 100, and can be overlapped with each other through the first overlapping interface 1042 and the second overlapping interface 1052 with opposite openings, wherein when overlapping with each other, the first overlapping vertical plate 1045 extends into the second overlapping interface 1052, and the second overlapping vertical plate 1055 extends into the first overlapping interface 1042, so as to realize the connection of two adjacent photovoltaic plane tiles 100, and the overlapping is realized through the structure of the photovoltaic plane tile 100 itself, without the need to add additional overlapping components, thereby reducing the types of components when laying the photovoltaic plane tile 100, making the overlapping more convenient and the integrity more compact, and reducing the assembly and matching relationship with separate overlapping components, thereby reducing the installation accuracy.

[0056] In addition, in one embodiment of the present invention, a plurality of first ribs 1043 parallel to the first overlapping vertical plate 1045 are provided in the first overlapping interface 1042, and a plurality of second ribs 1053 parallel to the second overlapping vertical plate 1055 are provided in the second overlapping interface 1052. Fig.13The first convex ribs 1043 and the second convex ribs 1053 in the first overlap joint 1042 and the second overlap joint 1052 are staggered and engaged with each other to improve the strength of the left and right overlaps. The first convex ribs 1043 and the second convex ribs 1053 can also support the first overlap bottom plate 1044 and the second overlap bottom plate 1054 to each other, forming a cavity in the first overlap joint 1042 and the second overlap joint 1052, which can be used as a rainproof cavity to facilitate the discharge of rainwater along the cavity.

[0057] In addition, in the actual design, in order to ensure that the front sides of the two overlapping photovoltaic flat tiles 100 are at the same height, the first overlapping portion and the second overlapping portion can be arranged in space as a structure distributed up and down, so that when overlapping, the height of the photovoltaic flat tiles 100 will not be affected by the interaction between them. This makes it convenient to ensure the flatness of the roof when overlapping.

[0058] See attached Fig.16 The second aspect of the present application discloses a photovoltaic flat tile 100 system, which is arranged on a roof, and includes a plurality of photovoltaic flat tiles 100 arranged in an array along a first direction and a second direction. The photovoltaic flat tile 100 adopts the photovoltaic flat tile 100 disclosed in the first aspect, and the upper frame 102 and the lower frame 103 are arranged in the first direction, and the first side frame 104 and the second side frame 105 are arranged in the second direction. Two adjacent photovoltaic flat tiles 100 arranged along the second direction can be overlapped and connected to each other through a first overlap portion and a second overlap portion.

[0059] When the photovoltaic flat tile is installed on the roof, the photovoltaic flat tile 100 is generally arranged along the slope of the roof. During installation, the upper frame 102 is in a high position and the lower frame 103 is in a low position. The photovoltaic flat tile 100 has a tendency to slide downward along the roof under the action of its own gravity. A hanging plate is set on the upper frame 102. After the photovoltaic flat tile 100 is hung on the installation hanger 200, it will slide downward along the roof under the action of its own gravity and lock on the installation hanger 200, which has a similar "self-locking" effect. In contrast, if the first hanging structure is set on the lower frame 103, the upper frame 102 of the photovoltaic flat tile 100 will have a tendency to tip over around the hanging point of the lower frame 103 under the action of gravity, and its stability is poor.

[0060] The mounting hanger 200 in this embodiment includes a mounting portion 201 and a hanging portion 202. The mounting portion 201 is used to fix the tile strip 500 connected to the roof, and the hanging portion 202 is hung with the first hanging structure to limit the movement of the photovoltaic flat tile 100 along the first direction. The mounting hanger 200 in this technical solution is directly fixed on the tile strip 500 of the roof. When arranging the photovoltaic flat tile 100, the photovoltaic flat tile 100 is adapted and installed according to the tile strip 500 of the roof structure itself, and the combination with the roof is better. In the specific construction, the photovoltaic flat tile 100 is hung and connected between the frame and the hanging portion 202 of the mounting hanger 200, which is convenient for installation. Moreover, the overall structure of the mounting hanger 200 is simple and convenient to design, which increases the design fault tolerance of each component, reduces the precision requirements of the photovoltaic flat tile 100 during construction and installation, and the position of the photovoltaic flat tile 100 is easy to adjust, which improves the construction efficiency.

[0061] See attached Fig. 9 , 10 11. The mounting hanger 200 in this embodiment is used to mount the photovoltaic flat tile 100 on the roof. The mounting hanger 200 includes a mounting portion 201 and a mounting portion 202. The mounting portion 201 is used to fix the tile hanging strip 500 connected to the roof. The tile hanging strip 500 is an important component for fixing the tiles on the roof. It is usually made of wood or metal. The main function of the tile hanging strip 500 is to support and fix the tiles to ensure that the tiles will not slide or fall off under natural conditions such as wind and rain. The hanging portion 202 is used to cooperate with the frame of the photovoltaic flat tile 100 to limit the downward movement of the photovoltaic flat tile 100 along the roof. When arranging the photovoltaic flat tile 100, the photovoltaic flat tile 100 is adapted and installed according to the tile hanging strip 500 of the roof's own structure, and has better integration with the roof. In the actual construction, the photovoltaic flat tile 100 is connected by hanging between the frame and the hanging portion 202 of the mounting hanger 200, which is convenient for installation. Moreover, the overall structure of the mounting hanger 200 is simple and convenient to design, which increases the design tolerance of each component and reduces the precision requirements of the photovoltaic flat tile 100 during construction and installation. The position of the photovoltaic flat tile 100 is easy to adjust, thereby improving construction efficiency.

[0062] During the specific installation, the mounting hanger 200 can be fixed on the top surface or upper side of the tile hanging strip 500 through the mounting portion 201. Since the roof has a certain slope, fixing the mounting hanger 200 on the top surface or upper side of the tile hanging strip 500 can improve the stability of the mounting hanger 200, thereby improving the bearing capacity of the photovoltaic flat tile 100.

[0063] The mounting portion 201 of one embodiment of the utility model is provided with a mounting hole 2011 for fixed connection with the tile hanging strip 500. During construction, the mounting hanger 200 is fixed to the tile hanging strip 500 by passing connecting parts such as bolts, rivets, studs or screws through the mounting hole 2011. Of course, in actual design, the mounting hanger 200 can also be fixed by one or more methods such as plug-in, snap-on connection or welding.

[0064] In order to further improve the structural strength and load capacity of the installation hanger 200, the installation hanger 200 of one embodiment of the utility model further includes a clamping portion 203, one of the installation portion 201 and the clamping portion 203 cooperates with the top surface of the tile hanging strip 500, and the other cooperates with the upper side surface of the tile hanging strip 500. Fig.15 The mounting portion 201 of the mounting hanger 200 is fixed on the top surface of the tile hanging strip 500, and the clamping portion 203 cooperates with the upper side surface of the tile hanging strip 500, so that the mounting portion 201 and the clamping portion 203 respectively cooperate with the two adjacent side edges of the tile hanging strip 500, and the two cooperate with each other, so that the mounting hanger 200 relies more stably on the tile hanging strip 500, thereby improving the structural strength and bearing capacity of the mounting hanger 200.

[0065] The mounting hanger 200 in this embodiment is preferably set to a material with high strength and light weight, and specifically can be made of carbon steel or aluminum alloy. Of course, it can also be set to other materials. The mounting portion 201, the hanging portion 202 and the clamping portion 203 are all set to a flat plate structure. In this way, the overall structure of the mounting hanger 200 is simple, saving materials and reducing production costs. When carbon steel is selected, the mounting hanger 200 is formed in one piece by cold bending. The specific structure is shown in the attached Fig.10 When aluminum alloy is used, it is extruded. The specific structure is shown in the attached Fig.11 Of course, in actual design, the specific shapes and structures of the mounting portion 201, the hanging portion 202 and the clamping portion 203 are not limited to the flat structure, and can also be adaptively modified according to the actual application scenario, as long as they can meet the corresponding functions.

[0066] See attached Fig. 9 , 15 16. Since there is generally a 90° right angle between the top surface and the upper side surface of the tile hanging strip 500, taking into account the production error and to enable the installation hanger 200 to be better assembled and matched with the tile hanging strip 500, the angle α between the clamping portion 203 and the mounting portion 201 of the utility model is set to 95-105°. In this way, during the construction process, the clamping portion 203 and the mounting portion 201 of the installation hanger 200 can better cooperate with the 90° right angle of the tile hanging strip 500.
