[0030] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figure 1 and Figure 2The photovoltaic power generation device 1 includes a plurality of photovoltaic panels 100 and a plurality of first sliding mechanisms 200. A first sliding mechanism 200 is disposed between two adjacent photovoltaic panels 100, and is connected to two adjacent photovoltaic panels 100 respectively. A first sliding mechanism 200 is provided between any two adjacent photovoltaic panels 100. The first sliding mechanism 200 is used to drive the photovoltaic panels 100 to stack or unfold, thereby facilitating the assembly and disassembly of the photovoltaic power generation device 1.

[0032] For ease of understanding, the directions are defined as follows: the first axis X is the width direction of the photovoltaic panel 100, the second axis Y is the thickness direction of the photovoltaic panel 100, and the third axis Z is the length direction of the photovoltaic panel 100. The first axis X, the second axis Y, and the third axis Z are perpendicular to each other.

[0033] For the photovoltaic panel 100 mentioned above, please refer to... Figure 2 and Figure 3 The photovoltaic panel 100 is provided with a first end 110 and a second end 120 arranged opposite each other along a first axial direction X, and each photovoltaic panel 100 is arranged sequentially along a second axial direction Y. The photovoltaic panel 100 is provided with a light-facing surface 130 and a back-lighting surface 140. The light-facing surface 130 is used to absorb light energy, and the light-facing surface 130 and the back-lighting surface 140 are arranged opposite each other along the second axial direction Y.

[0034] It should be noted that the photovoltaic panels 100 include at least a head photovoltaic panel and a tail photovoltaic panel. Among all the photovoltaic panels 100, the two photovoltaic panels 100 located at both ends along the second axis Y are the head photovoltaic panel and the tail photovoltaic panel, respectively. The other photovoltaic panels 100 are located between the back surface 140 of the head photovoltaic panel and the light-facing surface 130 of the tail photovoltaic panel.

[0035] For the first sliding mechanism 200 mentioned above, please refer to Figure 2 and Figure 3The first sliding mechanism 200 includes a linear drive assembly 210 and a moving member 220. Between any two adjacent photovoltaic panels 100, the linear drive assembly 210 is disposed on one of the two adjacent photovoltaic panels 100, and the moving member 220 is disposed on the second end 120 of the other. The moving member 220 is connected to the linear drive assembly 210, which can drive the moving member 220 to reciprocate along a first axis X, thereby causing the linear drive assembly 210 to drive the relative reciprocating motion between the two adjacent photovoltaic panels 100. Thus, the first sliding mechanism 200 enables all photovoltaic panels 100 to switch between a retracted state and an unfolded state. In the stowed state, in any two adjacent photovoltaic panels 100, along the second axis Y, the first end 110 of one photovoltaic panel 100 is aligned with the first end 110 of the other photovoltaic panel 100, and the second end 120 of one photovoltaic panel 100 is aligned with the second end 120 of the other photovoltaic panel 100. This allows the photovoltaic panels 100 to be stacked along the second axis Y, reducing the space occupied by all photovoltaic panels 100 and improving portability. In the unfolded state, in any two adjacent photovoltaic panels 100, along the second axis Y, the first end 110 of one photovoltaic panel 100 is aligned with the second end 120 of the other photovoltaic panel 100, ensuring that the light-facing surface 130 of each photovoltaic panel 100 is fully exposed, and each unfolded photovoltaic panel 100 receives sufficient sunlight. Through the above configuration, the first sliding mechanism 200 reduces the workload of disassembling and assembling the photovoltaic panels 100 one by one, such as the handling after disassembly and assembly, thus improving the disassembly and assembly efficiency of the photovoltaic power generation device 1.

[0036] The linear drive assembly 210 described above includes a motor (not shown) and a lead screw 211. Between two adjacent photovoltaic panels 100, the motor and lead screw 211 are mounted on the same photovoltaic panel 100. The lead screw 211 is rotatably mounted on the photovoltaic panel 100 and is positioned along a first axial direction X. The lead screw 211 is connected to the motor, which drives the lead screw 211 to rotate. A movable member 220 is mounted on another photovoltaic panel 100 and has a threaded hole through which the lead screw 211 passes and is screwed. Thus, by driving the lead screw 211 to rotate via the motor, the movable member 220 is forced to reciprocate along the first axial direction X, thereby driving the two adjacent photovoltaic panels 100 to perform relative reciprocating motion. In some other embodiments, the linear drive assembly 210 includes a cylinder (not shown) and a piston (not shown). The piston is connected to the cylinder, and the cylinder can drive the piston to reciprocate along the first axial direction X. Between two adjacent photovoltaic panels 100, a cylinder is fixed to one photovoltaic panel 100, and a movable component 220 is disposed on the other photovoltaic panel 100. The movable component 220 is connected to a piston, and by driving the piston to move along the first axis X, the two adjacent photovoltaic panels 100 can be forced to move relative to each other. It should be noted that the structure of the linear drive assembly 210 and the movable component 220 is not limited to this; it is sufficient as long as the linear drive mechanism 210 can drive the movable component 220 to reciprocate along the first axis X.

[0037] In some embodiments, the first sliding mechanism 200 further includes a guide mechanism 230. The guide mechanism 230 includes a guide rail 231 and a slider 232. The guide rail 231 is arranged along a first axial direction X, and the slider 232 is slidably connected to the guide rail 231. At least one guide mechanism 230 is provided between two adjacent photovoltaic panels 100. In each guide mechanism 230, the slider 232 is disposed on one of the two adjacent photovoltaic panels 100, and the guide rail 231 is disposed on the other. The guide mechanism 230 restricts the movement of the two adjacent photovoltaic panels 100 to relative to each other along the first axial direction X. Optionally, the guide rail 231 extends from the first end 110 of the photovoltaic panel 100 to the second end 120, the lead screw 211 extends from the first end 110 of the photovoltaic panel 100 to the second end 120, and the slider 232 and the moving part 220 are both located at the first end 110 of the photovoltaic panel 100. In this way, the maximum stroke when two adjacent photovoltaic panels 100 move relative to each other is increased, so that the area of ​​the light-facing surface 130 of one photovoltaic panel 100 exposed by the other photovoltaic panel 100 is increased, thereby improving the light energy absorption effect.

[0038] In some embodiments, the guide rail 231 is provided with a first slide groove 231a and a second slide groove 231b, which are sequentially arranged along the second axis Y, and the first slide groove 231a and the second slide groove 231b are connected. The width of the first slide groove 231a is greater than the width of the second slide groove 231b. The slider 232 is provided with a first sliding part 232a and a second sliding part 232b. The width of the first sliding part 232a matches the width of the first slide groove 231a and is inserted into the first slide groove 231a. The width of the second sliding part 232b matches the width of the second slide groove 231b and is inserted into the second slide groove 231b. With the above arrangement, the first sliding part 232a cannot slide out of the first slide groove 231a along the second axis Y, reducing the risk of the slider 232 separating from the guide rail 231, thereby ensuring the stable movement of the photovoltaic panel 100.

[0039] Optionally, the guide rail 231 can also be a guide rod (not shown), which is arranged along the first axis X, and the slider 232 passes through and is slidably connected to the guide rod.

[0040] It should be noted that the guide rail 231 can be integrally formed with the photovoltaic panel 100, that is, both the first groove 231a and the second groove 231b are formed on the photovoltaic panel 100. Alternatively, the guide rail 231 can also be a component independent of the photovoltaic panel 100.

[0041] In some embodiments, the guide rail 231 is provided with a first limiting structure and a second limiting structure, which are used to limit the slider 232 to restrict its stroke. The first limiting structure is located at the first end 110, and the second limiting structure is located at the second end 120. In the retracted state, the slider 232 abuts against the first limiting structure. In the use state, the slider 232 abuts against the second limiting structure. The first and second limiting structures prevent the slider 232 from sliding off the track along the first axial direction X, thereby preventing two adjacent photovoltaic panels 100 from detaching. In addition, the provision of the first and second limiting structures facilitates the determination of the retracted and unfolded states and facilitates the control of the first sliding mechanism 200. Optionally, both the first and second limiting structures can be limiting blocks, or both can be set as the groove walls of the first sliding groove 231a.

[0042] In some embodiments, between any two adjacent photovoltaic panels 100, the linear drive assembly 210 and the guide rail 231 are both disposed on the back surface 140 of one of the two adjacent photovoltaic panels 100, and the moving member 220 and the slider 232 are both disposed on the light-facing surface 130 of the other. This reduces the risk of the linear drive assembly 210 and the guide rail 231 occupying the light-facing surface 130 of the photovoltaic panel 100, thereby increasing the area of ​​the light-facing surface 130 available for absorbing light energy, and thus improving the efficiency of the photovoltaic panel 100 in absorbing solar energy.

[0043] In some embodiments, the number of guide mechanisms 230 between any two adjacent photovoltaic panels 100 is two. Along the third axis Z, the two guide mechanisms 230 are located on both sides of the photovoltaic panel 100, thereby making the relative movement between the two adjacent photovoltaic panels 100 more stable.

[0044] In some embodiments, combined with Figure 4 Alternatively, the linear drive assembly 210 and the moving part 220 may not be included. The first end 110 of the head photovoltaic panel is provided with a first connecting part 101, and the second end 120 of the tail photovoltaic panel is provided with a second connecting part 102. The first sliding mechanism 200 also includes a telescopic assembly 240, which includes an electric telescopic rod. The electric telescopic rod is arranged along the first axis X, with one end fixed to the first connecting part 101 and the other end fixed to the second connecting part 102.

[0045] During the process of switching from the retracted state to the unfolded state, the telescopic component 240 extends, causing the first connecting part 101 and the second connecting part 102 to move away from each other, so that the head photovoltaic panel and the tail photovoltaic panel move away from each other. When the slider 232 connected to one photovoltaic panel 100 abuts against the second limiting structure connected to the other photovoltaic panel 100 in any two adjacent photovoltaic panels 100, one photovoltaic panel 100 drives the other photovoltaic panel 100 to move along the first axis X until, in any two adjacent photovoltaic panels 100, along the second axis Y, the first end 110 of one photovoltaic panel 100 is aligned with the second end 120 of the other photovoltaic panel 100.

[0046] When switching from the unfolded state to the retracted state, the telescopic component 240 retracts, causing the first connecting part 101 and the second connecting part 102 to move closer together, so that the head photovoltaic panel and the tail photovoltaic panel move closer together. When the slider 232 connected to one photovoltaic panel 100 abuts against the first limiting structure connected to the other photovoltaic panel 100 in any two adjacent photovoltaic panels 100, one photovoltaic panel 100 drives the other photovoltaic panel 100 to move along the first axis X until, in any two adjacent photovoltaic panels 100, along the second axis Y, the first end 110 of one photovoltaic panel 100 is aligned with the first end 110 of the other photovoltaic panel 100, and the second end 120 of one photovoltaic panel 100 is aligned with the second end 120 of the other photovoltaic panel 100.

[0047] It is understood that the structure of the telescopic component 240 is not limited to this. As long as the telescopic component 240 has a telescopic function and can drive the first connecting part 101 and the second connecting part 102 to move away from or towards each other, it is acceptable.

[0048] In this embodiment of the invention, the photovoltaic power generation device 1 includes a plurality of photovoltaic panels 100 and a plurality of first sliding mechanisms 200. Each photovoltaic panel 100 includes a first end 110 and a second end 120 disposed opposite each other along a first axial direction X. The plurality of photovoltaic panels 100 are disposed along a second axial direction Y, with the first axial direction X and the second axial direction Y being perpendicular to each other. A first sliding mechanism 200 is disposed between two adjacent photovoltaic panels 100 along the second axial direction Y, and is connected to each of the two adjacent photovoltaic panels 100 along the second axial direction Y. The first sliding mechanism 200 allows the two adjacent photovoltaic panels 100 to move relative to each other along the first axial direction X. The plurality of photovoltaic panels 100 have a stowed state and an unfolded state. In the stowed state, in any two adjacent photovoltaic panels 100, along the second axial direction Y, the first end 110 of one photovoltaic panel 100 is aligned with the first end 110 of another photovoltaic panel 100, and the second end 120 of one photovoltaic panel 100 is aligned with the second end 120 of another photovoltaic panel 100. Thus, the entire photovoltaic power generation device 1 occupies a small space and is easy to transport. In the unfolded state, in any two adjacent photovoltaic panels 100, along the second axis Y, the first end 110 of one photovoltaic panel 100 is aligned with the second end 120 of the other photovoltaic panel 100, so that each photovoltaic panel 100 can receive sufficient sunlight. By controlling each of the first sliding mechanisms 200, all photovoltaic panels 100 can be switched between the retracted state and the unfolded state, thereby improving the assembly and disassembly efficiency of the photovoltaic power generation device 1.

[0049] This utility model provides an embodiment of a photovoltaic power generation system. Please refer to [link / reference]. Figure 1 The photovoltaic power generation system includes the photovoltaic power generation device 1 described above. The structure and function of the photovoltaic power generation device 1 can be found in the above embodiments, and will not be described in detail here.

[0050] In some embodiments, the photovoltaic power generation system is an energy storage container 2. The energy storage container 2 also includes a container body 21, a second sliding mechanism (not shown), and an energy storage unit (not shown). The second sliding mechanism is disposed on the container body 21, and the photovoltaic power generation device 1 is connected to the second sliding mechanism. The second sliding mechanism is used to drive the photovoltaic power generation device 1 out of or back into the container body 21, thereby facilitating the installation and removal of the photovoltaic power generation device 1. The energy storage unit is disposed on the container body 21, and the photovoltaic power generation device 1 is electrically connected to the energy storage unit. The energy storage unit is used to store the electrical energy converted by the photovoltaic power generation device 1 and to charge external electronic devices. The photovoltaic power generation device 1 is used to absorb solar energy and convert it into electrical energy. Thus, by integrating photovoltaic power generation, energy storage, and charging functions into the container body 21, the system integration is improved. This reduces the floor space required and facilitates transportation.

[0051] For the aforementioned housing 21, please refer to... Figure 1 The housing 21 has a receiving cavity and an opening, with the receiving cavity communicating with the opening. The receiving cavity is used to house the photovoltaic power generation device 1, and the opening is used for the photovoltaic power generation device 1 to extend or retract into the receiving cavity. In the housed state, the photovoltaic power generation device 1 is located inside the receiving cavity, and the first end 110 of each photovoltaic panel 100 is located on the side of the receiving cavity where the opening is located. When each photovoltaic panel 100 extends out of the receiving cavity, the first end 100 of each photovoltaic panel extends out of the opening first. In the unfolded state, all photovoltaic panels 100 extend out of the receiving cavity, and the first end 110 of the tail photovoltaic panel extends out of the receiving cavity, while the second end 120 of the tail photovoltaic panel is located at the opening. It can be understood that in the housed state, the second end 120 of the tail photovoltaic panel can extend completely out of the receiving cavity or be partially located inside the receiving cavity.

[0052] For the second sliding mechanism described above, please refer to Figures 1-3 A second sliding mechanism is disposed in the housing 21 and connected to the tail photovoltaic panel. The second sliding mechanism is used to drive the tail photovoltaic panel to move relative to the housing 21 along the first axis X. The second sliding mechanism includes a driving member and a sliding member. The driving member is disposed in the housing, and the sliding member is connected to the driving member. The driving member can drive the sliding member to reciprocate along the first axis X. The tail photovoltaic panel is connected to the driving member, and the driving member can drive the tail photovoltaic panel to extend or retract into the cavity. In the retracted state, the tail photovoltaic panel is located in the receiving cavity; in the unfolded state, the first end 110 of the tail photovoltaic panel extends out of the receiving cavity, and the second end 120 of the tail photovoltaic panel is located at the opening. It can be understood that the driving member can be a lead screw mechanism, a cylinder mechanism, a gear and rack mechanism, etc., as long as the driving member can drive the sliding member to reciprocate along the first axis X.

[0053] In some embodiments, the energy storage container 2 further includes several support members 23, which are support rods. In the unfolded state, along the third axis Z, a support rod is respectively provided on both sides of the first end 110 of a photovoltaic panel 100, and each support rod is located on the back surface 140 of the photovoltaic panel 100. One end of the support rod is connected to the photovoltaic panel 100, and the other end of the support rod is used to support the ground. It is understood that the arrangement of the support members 23 is not limited to this, as long as the support members 23 can stably support the photovoltaic power generation device 1 on the ground in the unfolded state. Optionally, the support rods can be connected to the photovoltaic panel 100 by means of snap-fit, riveting, screwing, etc.

[0054] It should be noted that during the process of switching from the retracted state to the unfolded state, each photovoltaic panel 100 extends out one by one from the head photovoltaic panel to the tail photovoltaic panel. In this way, the support component 23 can be installed after a photovoltaic panel 100 is extended, thereby achieving stable support during the extension process of each photovoltaic panel 100.

[0055] In some embodiments, the energy storage container 2 further includes an external photovoltaic panel 22, which is disposed on the top outer wall of the container body 21. The light-facing surface 130 of the external photovoltaic panel 22 is disposed on the side of the external photovoltaic panel 22 away from the container body 21. The photovoltaic panel 100 is electrically connected to the energy storage unit. By providing the external photovoltaic panel 22, the area of ​​the energy storage container 2 that receives sunlight when generating electricity is increased.

[0056] In some embodiments, the energy storage container 2 further includes a baffle (not shown), which is rotatably mounted on the container body 21, with the baffle's axis of rotation parallel to the third axis Z. One end of the baffle is rotatably connected to the side of the opening on the container body 21, and by rotating the baffle, the other end of the baffle can open or close the opening. When the photovoltaic power generation device 1 is housed in the receiving cavity, the baffle closes the opening, preventing foreign objects from entering the receiving cavity and reducing the risk of the photovoltaic power generation device 1 detaching from the receiving cavity during transportation, thereby facilitating transportation.

[0057] In some embodiments, please refer to Figure 5The energy storage container also includes an energy management system 24, an energy storage converter 26, an inverter 27, and a charging pile 28. The photovoltaic power generation device 1 is electrically connected to the inverter 27. The energy storage unit is a battery pack 25, which is electrically connected to the energy storage converter 26. The energy storage converter 26 is electrically connected to both the inverter 27 and the charging pile 28. The energy storage converter 26, inverter 27, and charging pile 28 are all communicatively connected to the energy management system 24. This allows for real-time acquisition of photovoltaic power generation, energy storage status, and load demand data. The operating point of the photovoltaic power generation is optimized using the MPPT (Maximum Power Point Tracking) algorithm to maximize energy capture. The charging and discharging strategy of the energy storage system is optimized based on load demand and fluctuations in photovoltaic power generation. The photovoltaic power generation and energy storage capacity are rationally configured according to load demand, while also considering photovoltaic power consumption and space allocation. It should be noted that when charging pile 28 is operating, photovoltaic power generation is prioritized to supply power to charging pile 28, that is, power is supplied through photovoltaic panels, and the remaining electricity is stored through the energy storage unit. At the same time, the operating power of charging pile 28 and energy storage unit is dynamically adjusted according to the power generation situation. When photovoltaic power generation is insufficient, the charging power can be reduced or the energy storage unit can provide power.
