[0068] With such arrangement, the corner code structure 16 serves as a relatively simple and effective connecting and fixing component. After the first plug-in block and the second plug-in block are inserted into the edge strip structure 11, they are squeezed and snapped into place, so that the profiles are fixed more tightly, thereby improving the mechanical properties of the photovoltaic energy storage frame 10.

[0072] Exemplarily, the first profile 115 is a trough body opened along the first direction, and the shape and size of the interior of the trough body are consistent with the shape and size of the first energy storage system 12. First, the first energy storage system 12 is placed in the trough body, and then the cover plate 1165 is covered on the trough body along the first direction so that the first energy storage system 12 is against the cover plate 1165, and then the photovoltaic laminate 20 is placed on the cover plate 1165, and the photovoltaic laminate 20 leads out the conductor to connect to the first conductive structure 13 and the connection is provided with insulating and waterproof materials such as silicone, and then the third profile 117 is buckled and fixed to the first profile 115 so that the connecting plate 1166 is at the end of the trough body facing away from the installation space along the second direction and the first pressing plate 1161 can press and fix the photovoltaic laminate 20, and finally the angle code structure 16 is inserted into the cavity formed by the first profile 115 and the third profile 117 to connect and fix the two side strip structures 11.

When the first energy storage management unit is in the second conductive state, the energy generated by the photovoltaic laminate 20 flows through the first conductive structure 13 and the first input terminal and then directly output through the first output terminal.

[0073] Exemplarily, the conductor and the first conductive structure 13 can be connected to each other by welding, clamping, etc. It can be understood that the input voltage requirement of the first input terminal can match the output voltage of the photovoltaic laminate 20, and the output voltage of the photovoltaic laminate 20 is slightly greater than the input voltage of the first input terminal.

[0074] Exemplarily, the outer corner code structure 16 and the inner corner code structure 16 can be used simultaneously to connect and fix a long side strip structure 11 and a short side strip structure 11. In other embodiments, when only the outer corner code is used for fixing, the slots of the connected long side strip structure 11 and the short side strip structure 11 are conductive and used as conductive channels, so that the wire directly connects the first energy storage system 12 of the two slots.

The first profile 115 includes a slot body and an extension plate 1167 connected to the slot body. The second profile 116 includes a connecting plate 1166 and a first pressing plate 1161, a second pressing plate 1162 and a cover plate 1165 which are sequentially arranged on the connecting plate 1166 in a first direction. The first pressing plate 1161 and the second pressing plate 1162 are used to define the clamping groove 111. The cover plate 1165 is buckled on the slot body to define the tube cavity 112. The cover plate 1165, the extension plate 1167, the second pressing plate 1162 and the connecting plate 1166 are used to define the cable cavity 114. The cover plate 1165 has a wiring hole connecting the cable cavity 114 and the tube cavity 112. The photovoltaic energy storage frame 10 also includes a water-cooled host (not shown), which is located in the cable cavity 114 and is thermally coupled to the first energy storage system 12.

[0076] With such arrangement, the cable cavity 114 and the tube cavity 112 can be connected and the cable cavity 114 accommodates the cable and the water-cooled host, thereby reducing the working temperature of the first energy storage system 12 and increasing the functionality of the photovoltaic energy storage frame 10 .

[0077] Exemplarily, the first energy storage system 12 is first placed in the slot of the first profile 115 so that the first energy storage system 12 is electrically connected to the first conductive structure 13, and then the second profile 116 is fixed on the first profile 115 so that the cover plate 1165 is buckled in the slot, and the cable cavity 114 defined by the cover plate 1165, the extension plate 1167, the second pressing plate 1162 and the connecting plate 1166 is used to accommodate the cable and the water-cooled host, and the wiring hole of the cover plate 1165 facilitates the cable to enter the tube cavity 112 from the cable cavity 114. The clamping groove 111 formed by the first pressing plate 1161 and the second pressing plate 1162 is used to compress and fix the photovoltaic laminate 20. Finally, the angle code structure 16 is inserted into the cavity formed by the first profile 115 and the second profile 116 to connect and fix the two side strip structures 11. When the first energy storage management unit is in the first conductive state, the energy generated by the photovoltaic laminate 20 is stored in the first energy storage unit 122 through the first conductive structure 13 and the first input terminal, and is output through the first output terminal when the stored electric energy is needed. When the first energy storage management unit is in the second conductive state, the energy generated by the photovoltaic laminate 20 is directly used after flowing through the first output terminal through the first conductive structure 13 and the first input terminal.

[0078] See also Fig. 9 and Fig.10 In some embodiments, the photovoltaic energy storage frame 10 also includes a second energy storage system 15, the second energy storage system 15 includes a second energy storage unit (not shown) and a second energy storage management unit (not shown), and the second energy storage unit includes a second input terminal and a second output terminal.

[0079] In this arrangement, the first energy storage system 12 is connected to the second energy storage system 15 and both the first energy storage system 12 and the second energy storage system 15 have two conductive states, making the energy running path more diverse. The second energy storage unit is detachably connected to the first conductive structure 13, which is convenient for replacing the easily damaged second energy storage unit. The detachable second energy storage unit increases the use range of the stored energy.

[0080] It is understandable that the side strip structure 11 may also include a third energy storage system, a fourth energy storage system, etc. Each energy storage system has two conductive states, and each energy storage system can be detachably connected to a first conductive structure 13 or multiple first conductive structures 13.

[0081] See also Fig. 9 and Fig.10 In some embodiments, the edge strip structure 11 includes a first profile 115 and a second profile 116, the first profile 115 includes a first tube body 1152 and an extension plate 1167 connected to the first tube body 1152, the first tube body 1152 has a tube cavity 112, the second profile 116 includes a connecting plate 1166 and a first pressing plate 1161, a second pressing plate 1162, a cover plate 1165 and a support plate 1168 which are sequentially arranged on the connecting plate 1166 along the first direction. The first pressing plate 1161 and the second pressing plate 1162 are used to define the clamping groove 111, the cover plate 1165, the extension plate 1167, the second pressing plate 1162 and the connecting plate 1166 are used to define the cable cavity 114, a portion of the first tube 1152 is embedded between the cover plate 1165 and the supporting plate 1168, the extension plate 1167 and the first tube 1152 define the installation groove 113, and the installation groove 113 is located on the side of the extension plate 1167 facing away from the cable cavity 114. The photovoltaic energy storage frame 10 includes a second energy storage system 15 located in the installation groove 113, and the second energy storage system 15 is electrically connected to the first conductive structure 13.

[0082] In this way, the photovoltaic energy storage frame 10 has the second energy storage system 15, which makes the energy operation path more diversified and improves the mechanical strength of the photovoltaic energy storage frame 10. The second energy storage system 15 can be detachably installed on the photovoltaic energy storage frame 10 following the first profile 115, which is convenient for replacing the second energy storage system 15 and increases the use range of the stored energy.

[0083] Exemplarily, firstly, the first energy storage system 12 is placed in the tube cavity 112 of the first tube body 1152, and then the second energy storage system 15 is placed in the extension plate 1167 of the second profile 116, the second input terminal of the second energy storage system 15 is electrically connected to the first conductive structure 13, and the first input terminal of the first energy storage system 12 is electrically connected to the second output terminal of the second energy storage system 15, and the cables and the water-cooled host are placed in the structure surrounded by the cover plate 1165, the extension plate 1167, and the second pressing plate 1162, and then the second profile 116 and the first profile 115 are fixed to form the installation groove 113 and the cable cavity 114. The wiring hole of the cover plate 1165 facilitates the cable to enter the tube cavity 112 from the cable cavity 114. The clamping groove 111 formed by the first pressing plate 1161 and the second pressing plate 1162 is used to compress and fix the photovoltaic laminate 20. Finally, the angle code structure 16 is inserted into the cavity formed by the first profile 115 and the second profile 116 to connect and fix the two side strip structures 11 .

[0084] Exemplarily, the first energy storage system 12 is much larger in capacity than the second energy storage system 15, and the first energy storage system 12 is disposed in the frame profile cavity. It is understandable that the second energy storage system 15 includes input electrical parameter adjustment function, buck-boost function, etc., and the second energy storage system 15 is easy to disassemble.

[0085] Exemplarily, the second energy storage unit is detachable and replaceable. After the second energy storage unit is detached, the use range of the stored energy can be increased. By replacing the second energy storage unit with full energy, the energy storage unit can become a continuously replaceable mobile power source for residents' lives.

[0086] It is understandable that due to the light intensity on the light-collecting surface of the photovoltaic laminate 20, the current and voltage values ​​output by the photovoltaic laminate 20 fluctuate greatly. Therefore, it is necessary to perform voltage step-up and voltage step-down and current step-down to match the second energy storage system before inputting the second energy storage system. Moreover, the change of electrical parameters at the input end affects the life of the energy storage device. The change of electrical parameters also needs to be implemented by the energy storage management unit. The devices corresponding to the energy storage management unit are easily damaged. Therefore, the energy storage management unit can be integrated on the outside of the frame to facilitate the replacement of damaged devices.

[0087] Exemplarily, when the first energy storage management unit is in the first conductive state and the second energy storage management unit is in the third conductive state, the energy generated by the photovoltaic laminate 20 is stored in the second energy storage unit through the electrical connection between the first conductive structure 13 and the second input terminal. At the same time, the energy generated by the photovoltaic laminate 20 is stored in the first energy storage unit 122 through the electrical connection between the first conductive structure 1 and the first input terminal 3. When the electric energy stored in the first energy storage unit 122 is needed, it is output through the first output terminal. When the electric energy stored in the second energy storage unit is used, it is output through the second output terminal.

[0088] Exemplarily, when the first energy storage management unit is in the first conductive state and the second energy storage management unit is in the fourth conductive state, the energy generated by the photovoltaic laminate 20 flows through the first conductive structure 13 and the second input terminal and then directly outputs through the second output terminal. At the same time, the energy generated by the photovoltaic laminate 20 is stored in the first energy storage unit 122 through the electrical connection between the first conductive structure 13 and the first input terminal, and is output through the first output terminal when the electric energy stored in the first energy storage unit 122 is needed;

[0089] Exemplarily, when the first energy storage management unit is in the second conductive state and the second energy storage management unit is in the third conductive state, the energy generated by the photovoltaic laminate 20 is stored in the second energy storage unit through the electrical connection between the first conductive structure 13 and the second input terminal, and is output through the second output terminal when the stored electric energy is needed. At the same time, the energy generated by the photovoltaic laminate 20 flows through the first conductive structure 13 and the first input terminal and then is directly outputted after passing through the first output terminal.

[0090] Exemplarily, when the first energy storage management unit is in the second conductive state and the second energy storage management unit is in the fourth conductive state, the energy generated by the photovoltaic laminate 20 flows through the first conductive structure 13 and the second input terminal through the second output terminal and is directly output. At the same time, the energy generated by the photovoltaic laminate 20 flows through the first conductive structure 13 and the first input terminal through the first output terminal and is directly output.

[0091] For example, the first cavity has a larger space, and the first energy storage unit 122 can be provided with two lithium batteries in parallel, so as to store more energy. It is understandable that the number of lithium batteries is set according to the space size of the cavity.

[0092] In other embodiments, when the storage capacity requirement is not high, only a portion of the side strip structures 11 of a photovoltaic laminate 20 may be provided with an energy storage function, and no energy storage is provided in the frames of the other side strip structures 11. For example, the side strip structures 11 of the long sides are provided with an energy storage system, while the side strip structures 11 of the short sides are not provided with an energy storage system, so as to increase the mechanical strength and facilitate electrical connection to the photovoltaic laminate 20.

[0093] See also Fig.11 , Fig.12 , Fig.13 and Fig.15 In some embodiments, the edge strip structure 11 includes a first profile 115 and a second profile 116. The first profile 115 includes a first tube 1152 and an extension plate 1167. The second profile 116 includes a connecting plate 1166 and a first pressing plate 1161, a second pressing plate 1162 and a second tube 1164 sequentially arranged on the connecting plate 1166 in a first direction.

The first tube 1152 is embedded between the second pressing plate 1162 and the second tube 1164. The angle code structure 16 also includes a connection portion 164 and a first clamping portion 163. A plurality of first plug blocks 161 are disposed at intervals on the connection portion 164. A plurality of second plug blocks 162 are disposed at intervals on the connection portion 164. Two adjacent side strip structures 11 form a water guide gap 17 corresponding to the connection portion 164. The installation space is connected to the outer circle of the installation space relative to the side strip structure 11 through the water guide gap 17. The first plug block 161 and the first clamping portion 163 plugged into the cable cavity 114 are used to clamp a portion of the wall of the second tube body 1164 and the extension plate 1167.

[0094] In this way, the first plug block 161 and the first clamping portion 163 clamp part of the tube wall of the second tube body 1164 and the extension plate 1167, thereby improving the fixing effect of the corner code structure 16 on the side strip structure 11. The position where the photovoltaic energy storage frame 10 uses the corner code structure 16 no longer has a frame structure, and the height of the corner code structure 16 is lower than the height of the first pressing plate 1161, so that the material or rainwater that blocks sunlight inside the photovoltaic laminate 20 can flow out of the photovoltaic energy storage frame 10 through the water guide gap 17.

[0095] Exemplarily, the first energy storage system 12 is first placed in the tube cavity 112 of the first tube body 1152, and the first input terminal of the first energy storage system 12 is electrically connected to the first conductive structure 13 and thus connected to the photovoltaic laminate 20, and then the second energy storage system 15 is placed inside the second tube body 1164, and the cable and the water-cooled host are placed in the cable cavity 114 of the second tube body 1164, and then the first tube body 1152 is embedded between the second pressing plate 1162 and the second tube body 1164.

The clamping groove 111 formed by the first pressing plate 1161 and the second pressing plate 1162 is used to compress and fix the photovoltaic laminate 20. Finally, the first plug block 161 of the angle code structure 16 is inserted into the cable cavity 114 so that the first clamping portion 163 and the first plug block 161 clamp part of the tube wall of the second tube body 1164 and the extension plate 1167 to connect and fix the long side strip structure 11 and the short side strip structure 11.

[0096] Exemplarily, when the first energy storage management unit is in the first conductive state and the second energy storage management unit is in the third conductive state, the energy generated by the photovoltaic laminate 20 is stored in the first energy storage unit 122 through the electrical connection between the first conductive structure 13 and the first input terminal, and at the same time, the energy generated by the photovoltaic laminate 20 is stored in the second energy storage unit through the electrical connection between the first conductive structure 13 and the second input terminal, and is output through the first output terminal when the electric energy stored in the first energy storage unit 122 needs to be used, and is output through the second output terminal when the electric energy stored in the second energy storage unit is used. Exemplarily, when the first energy storage management unit is in the first conductive state and the second energy storage management unit is in the fourth conductive state, the energy generated by the photovoltaic laminate 20 is stored in the first energy storage unit 122 through the electrical connection between the first conductive structure 13 and the first input terminal, and is output through the first output terminal when the stored electric energy needs to be used; at the same time, the energy generated by the photovoltaic laminate 20 flows through the first conductive structure 13 and the second input terminal and then directly outputs after passing through the second output terminal.
