Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0042] The following is combined Figures 1 to 6 The structure and working principle of the optical energy storage mechanism and optical energy storage device of this utility model are described in detail.

[0043] like Figures 1 to 6 As shown, a specific embodiment of the first aspect of this utility model provides a solar energy storage mechanism, which includes a solar photovoltaic component 100; the solar photovoltaic component 100 includes a plurality of solar photovoltaic modules 110 and at least one first hinge shaft 120; two adjacent solar photovoltaic modules 110 are hinged through the first hinge shaft 120, so that the plurality of solar photovoltaic modules 110 can switch between an unfolded state and a folded state.

[0044] In this embodiment, by hinged adjacent solar photovoltaic modules 110 with a first hinge axis 120, the solar photovoltaic modules 110 can rotate relative to the first hinge axis 120, thereby allowing the solar photovoltaic component 100 to switch between a folded state and an unfolded state. In the folded state, the photovoltaic energy storage mechanism is compact, facilitating storage and transportation, and reducing storage and relocation difficulties and costs. In the unfolded state, the solar photovoltaic modules 110 can fully utilize sunlight, improving the power generation efficiency of a single solar photovoltaic module. By setting the first hinge axis 120, the use of a foldable bracket to achieve the state switching of the solar photovoltaic component 100 can also be avoided, saving the space occupied by the foldable bracket and reducing the material cost of the photovoltaic energy storage mechanism.

[0045] Current solar energy storage systems typically utilize telescopic mechanisms to extend and retract solar photovoltaic panels. To ensure the panels are fully extended and not obstructed by overhead panels, an overlap is required at one end. This overlap increases space requirements when the panels are vertical and also raises material costs. In this embodiment, adjacent solar photovoltaic modules 110 are hinged together via a first hinge shaft 120, eliminating the need for an overlap at one end and reducing the height-related space requirements of the solar energy storage system.

[0046] Preferably, adjacent solar photovoltaic modules 110 can rotate 180° around the axis of the first hinge shaft 120, so that multiple solar photovoltaic modules 110 in the folded state can be stacked layer by layer.

[0047] It should be noted that "multiple" means at least two. In other words, the solar photovoltaic component 100 includes at least two solar photovoltaic modules 110.

[0048] Preferably, the number of first hinge shafts 120 is one less than the number of solar photovoltaic modules 110.

[0049] In some embodiments, the solar photovoltaic component 100 includes two solar photovoltaic modules 110 and a first hinge shaft 120; the two solar photovoltaic modules 110 are hinged together by the first hinge shaft 120.

[0050] In some other embodiments, the solar photovoltaic component 100 includes at least three solar photovoltaic modules 110 and at least two first hinge shafts 120; adjacent solar photovoltaic modules 110 are hinged together by a first hinge shaft 120.

[0051] like Figure 3 As shown, for example, a connector 111 is provided on the side of the solar photovoltaic module 110, and the connectors 111 of adjacent solar photovoltaic modules 110 are hinged through a first hinge shaft 120.

[0052] Furthermore, the solar photovoltaic module 110 includes a photovoltaic frame and a solar photovoltaic panel; the solar photovoltaic panel is mounted on the photovoltaic frame. The photovoltaic frames of adjacent solar photovoltaic modules 110 are hinged together via a first hinge shaft 120. By setting up a photovoltaic frame, the strength of the solar photovoltaic module 110 can be improved, thereby enhancing its ability to withstand strong winds. Specifically, connectors 111 are fixedly provided on the side of the photovoltaic frame, and the connectors 111 of adjacent solar photovoltaic modules 110 are hinged together via the first hinge shaft 120.

[0053] In some embodiments, the solar photovoltaic component 100 includes a plurality of first hinge shafts 120, with adjacent first hinge shafts 120 located on the same side of the solar photovoltaic module 110. Specifically, adjacent first hinge shafts 120 are located on the front or back of the solar photovoltaic module 110. Taking a solar photovoltaic component 100 comprising three solar photovoltaic modules 110 as an example, for ease of description, the three solar photovoltaic modules 110 are respectively named module one, module two, and module three; in the unfolded state, the three solar photovoltaic modules 110 are arranged sequentially from left to right; after folding module two over module one and module three over module two, module three is located between module one and module two, therefore sufficient space needs to be reserved between module one and module two for placing module three.

[0054] In some other embodiments, the solar photovoltaic component 100 includes a plurality of first hinge shafts 120, with adjacent first hinge shafts 120 located on both sides of the solar photovoltaic module 110. Specifically, adjacent first hinge shafts 120 are located on the front and back sides of the solar photovoltaic module 110, respectively. Taking a solar photovoltaic component 100 comprising three solar photovoltaic modules 110 as an example, for ease of description, the three solar photovoltaic modules 110 are named module one, module two, and module three, respectively. In the unfolded state, the three solar photovoltaic modules 110 are arranged sequentially from left to right. After folding module two over module one and module three over module two, the three solar photovoltaic modules 110 are stacked in sequence. That is, sufficient space does not need to be reserved between module one and module two for placing module three. In this embodiment, by arranging adjacent first hinge shafts 120 on both sides of the solar photovoltaic module 110, the space occupied by the photovoltaic energy storage mechanism in terms of height can be further reduced.

[0055] It should be noted that the front side of the solar photovoltaic module 110 is the side facing the sunlight, and the back side of the solar photovoltaic module 110 is the side away from the front side.

[0056] In some embodiments, the photovoltaic energy storage mechanism further includes an unfolding / retracting drive component 200; the unfolding / retracting drive component 200 is connected to the solar photovoltaic module 110 and is used to drive the solar photovoltaic module 110 to rotate relative to the first hinge axis 120, so that multiple solar photovoltaic modules 110 switch between folded and unfolded states. By setting the unfolding / retracting drive component 200, the unfolding and folding efficiency of the solar photovoltaic module 100 can be improved, saving manpower and increasing the state switching speed of the solar photovoltaic module 100.

[0057] like Figures 1 to 3As shown, the extension / retraction drive component 200 further includes at least one linkage structure 210 and at least one first telescopic drive member 220; the linkage structure 210 corresponds to the first hinge shaft 120, and the linkage structure 210 includes a first connecting rod 211, a second hinge shaft 212, and a second connecting rod 213; the second hinge shaft 212 is arranged parallel to the first hinge shaft 120, and the first connecting rod 211 and the second connecting rod 213 are hinged to each other through the second hinge shaft 212. The ends of the first connecting rod 211 and the second connecting rod 213 away from the second hinge shaft 212 are respectively hinged to the corresponding solar photovoltaic module 110; the first telescopic drive member 220 corresponds to the linkage structure 210; one end of the first telescopic drive member 220 is hinged to the solar photovoltaic module 110, and the other end is rotatably engaged with the corresponding second hinge shaft 212. By setting at least one linkage structure 210 and at least one first telescopic drive member 220, a solar photovoltaic module 110 can be folded and unfolded individually, making the unfolding and retraction of the solar photovoltaic component 100 more flexible.

[0058] It is understandable that the end of the first link 211 away from the second hinge axis 212 rotates with the corresponding solar photovoltaic module 110 around the first hinge axis 120, and the end of the second link 213 away from the second hinge axis 212 rotates with the corresponding solar photovoltaic module 110 around the first hinge axis 120.

[0059] Specifically, the first telescopic drive component 220 includes an electric telescopic rod, a hydraulic cylinder, or a pneumatic cylinder.

[0060] Preferably, the first telescopic drive component 220 is a hydraulic cylinder.

[0061] It should be noted that the correspondence between the connecting rod structure 210 and the first hinge shaft 120 means that the number of connecting rod structures 210 and the first hinge shaft 120 are equal and their positions correspond. Specifically, the first hinge shaft 120 and the corresponding connecting rod structure 210 are both located on the same side of the solar photovoltaic module 110. Preferably, the first hinge shaft 120 is located between the second hinge shaft 212 and the solar photovoltaic module 110.

[0062] It should be noted that the correspondence between the first telescopic drive member 220 and the connecting rod structure 210 means that the number of the first telescopic drive member 220 and the connecting rod structure 210 are equal.

[0063] like Figure 4 and Figure 5As shown, the unfolding / retracting drive component 200 further includes a first extending rope row 230, a first retracting rope row 240, and a second rotary drive component 250. One end of the first extending rope row 230 passes around the first hinge shaft 120 and connects to the back of the solar photovoltaic module 110, or one end connects to the front of the solar photovoltaic module 110. One end of the first retracting rope row 240 is connected to the back of the solar photovoltaic module 110. The second rotary drive component 250 is connected to the other end of the first extending rope row 230 and is used to switch the solar photovoltaic module 100 from a folded state to an unfolded state by pulling the first extending rope row 230. The second rotary drive component 250 is also connected to the other end of the first retracting rope row 240 and is used to switch the solar photovoltaic module 100 from an unfolded state to a folded state by pulling the first retracting rope row 240.

[0064] In this embodiment, the state switching of the solar photovoltaic component 100 is achieved by using a rope array in conjunction with the second rotation drive component 250, which can reduce material costs.

[0065] like Figure 4 and Figure 5 As shown, specifically taking two solar photovoltaic modules 110 as an example, the second rotary drive 250 is installed on the first solar photovoltaic module 110, one end of the first extending rope 230 passes around the first hinge shaft 120 and is connected to the back of the second solar photovoltaic module 110; one end of the first retracting rope 240 is connected to the back of the second solar photovoltaic module 110; the second rotary drive 250 is connected to the other end of the first extending rope 230, and is used to switch the solar photovoltaic component 100 from a folded state to an unfolded state by pulling the first extending rope 230; the second rotary drive 250 is also connected to the other end of the first retracting rope 240, and is used to switch the solar photovoltaic component 100 from an unfolded state to a folded state by pulling the first retracting rope 240.

[0066] Specifically, the second rotary drive unit 250 includes a motor and a winch drum; the other end of the first extending rope 230 is wound around the winch drum, and the other end of the first retracting rope 240 is also wound around the winch drum; the motor shaft is connected to the winch drum and is used to drive the winch drum to rotate axially around the first hinge shaft 120. When the motor drives the winch drum to rotate clockwise, the first extending rope 230 is tightened, which can pull the rear solar photovoltaic module 110 from the folded state to the unfolded horizontal state. When the motor drives the winch drum to rotate counterclockwise, the first retracting rope 240 is tightened, which can pull the rear solar photovoltaic module 110 from the unfolded horizontal state back to the folded state.

[0067] like Figures 1 to 2As shown, in some embodiments, the photovoltaic energy storage mechanism further includes a support component 300 and a first amplitude transformer 400; the support end of the support component 300 is rotatably engaged with the solar photovoltaic component 100 via a first rotating shaft, the axis of the first rotating shaft being parallel to the axis of the first hinge shaft 120; the first amplitude transformer 400 is mounted on the support component 300 and connected to the solar photovoltaic component 100, and is used to drive the solar photovoltaic component 100 to rotate relative to the first rotating shaft.

[0068] In this embodiment, the support component 300 provides an installation base for the solar photovoltaic component 100. The first amplitude-adjusting component 400 allows the solar photovoltaic component 100 to rotate relative to the first rotating shaft, thereby adjusting the angle of the solar photovoltaic component 100 and enabling it to track light.

[0069] like Figure 1 and Figure 2 As shown, exemplarily, the first luffing component 400 is a first luffing telescopic assembly; both ends of the first luffing telescopic assembly are hinged to the support component 300 and the solar photovoltaic component 100, respectively, so that the solar photovoltaic component 100 rotates relative to the first rotating shaft. The first luffing telescopic assembly can bear heavier loads and has better stability.

[0070] Preferably, the first luffing telescopic assembly includes an electric telescopic rod, a hydraulic cylinder, or a pneumatic cylinder.

[0071] In some embodiments, the support component 300 includes an installation platform 310 and a telescopic support assembly 320; the installation platform 310 and the solar photovoltaic component 100 are rotatably coupled via a first rotating shaft; the support end of the telescopic support assembly 320 is equipped with the installation platform 310, which is used to drive the solar photovoltaic component 100 to reciprocate along the telescopic direction of the telescopic support assembly 320 via the installation platform 310.

[0072] In this embodiment, by setting up the installation platform 310, an installation foundation can be provided for the solar photovoltaic component 100, and the telescopic support component 320 can adjust the height of the solar photovoltaic component 100 to expand the applicable scenarios of the photovoltaic energy storage mechanism.

[0073] Preferably, the telescopic support assembly 320 can telescopic in the up-down direction.

[0074] For example, the telescopic support assembly 320 includes an electrically operated telescopic rod, a hydraulic cylinder, or a pneumatic cylinder.

[0075] For example, the telescopic support assembly 320 includes a first multi-stage telescopic structure; the first multi-stage telescopic structure can extend or shorten step by step along the telescopic direction.

[0076] The first multi-stage telescopic structure includes at least the following two structures.

[0077] The first structure: The first multi-stage telescopic structure includes multiple telescopic cylinders and multiple first telescopic support drive components; each of the multiple first telescopic support drive components corresponds one-to-one with a telescopic cylinder. The first telescopic support drive component is installed inside the corresponding telescopic cylinder and is used to drive the adjacent telescopic cylinder to move in and out of the corresponding telescopic cylinder. Specifically, the first multi-stage telescopic assembly includes two telescopic cylinders and three first telescopic support drive components; the first first telescopic support drive component is installed inside the container via a rotating platform, and its drive end is connected to the bottom of the first telescopic cylinder, used to drive the first telescopic cylinder to move vertically. The second first telescopic support drive component is installed inside the first telescopic cylinder and connected to the second telescopic cylinder, used to drive the second telescopic cylinder to move in and out of the first telescopic cylinder. The third first telescopic support drive component is installed inside the second telescopic cylinder and connected to the solar photovoltaic component 100, used to drive the solar photovoltaic component 100 to move vertically.

[0078] like Figure 6 As shown, the second structure, the first multi-stage telescopic structure, includes multiple telescopic arms 321, a first extension rope 322, and a second telescopic drive component 323. The telescopic arms 321 are tubular, and multiple telescopic arms 321 are coaxially arranged. The second telescopic drive component 323 is mounted on the rotating platform of the rotating component and connected to the first telescopic arm 321. The fixed pulley of the first extension rope 322 is mounted on the top of the first telescopic arm 321, and one end of the rope is fixedly connected to the container, while the other end is connected to the second telescopic arm 321. The second telescopic drive component 323 drives the first telescopic arm 321 to move upward. The first telescopic arm 321, through the first extension rope 322, drives the second telescopic arm 321 to leave the inner cavity of the first telescopic arm 321 and move upward, allowing the solar photovoltaic component 100 to leave the container through the opening. By setting the first extension rope 322, one second telescopic drive component 323 can be used to drive the lifting of multiple telescopic arms 321, saving costs.

[0079] Preferably, the first multi-stage telescopic structure further includes a fixed arm 324, which is a tubular material. The fixed arm 324 is sleeved on the outside of the first telescopic arm 321, and the second telescopic drive member 323 drives the first telescopic arm 321 to move in and out of the fixed arm 324. The fixed arm 324 serves to protect the second telescopic drive member 323 and the multiple telescopic arms 321. Specifically, one end of the rope row of the first extending wheel rope 322 is connected to the top end of the fixed arm 324, and the other end is connected to the bottom end of the second telescopic arm 321.

[0080] Understandably, the diameter of the fixed arm 324 is larger than the diameter of the first telescopic arm 321. Among the multiple telescopic arms 321, the diameter gradually decreases from the outside in. Between adjacent telescopic arms 321, the smaller-diameter arm 321 can freely enter and exit the larger-diameter arm 321.

[0081] Preferably, the first multi-stage telescopic structure further includes a first retraction pulley rope 325; the fixed pulley of the first retraction pulley rope 325 is installed at the bottom end of the first telescopic arm 321, one end of the rope array of the first retraction pulley rope 325 is connected to the container, and the other end is connected to the second telescopic arm 321. Specifically, one end of the rope array of the first retraction pulley rope 325 is connected to the top end of the fixed arm 324, and the other end is connected to the bottom end of the second telescopic arm 321. When the second telescopic drive member 323 drives the first telescopic arm 321 to descend, the first telescopic arm 321 pulls the second telescopic arm 321 down through the rope array of the first retraction pulley rope 325, and the second telescopic arm 321 falls into the first telescopic arm 321, allowing the solar photovoltaic component 100 to enter the container through the opening. By setting the first retraction pulley rope 325, it can be ensured that the second telescopic arm 321 can fall smoothly into the first telescopic arm 321, and at the same time, it also plays a certain role in buffering the descent of the second telescopic arm 321.

[0082] Preferably, the first multi-stage telescopic structure further includes a mounting base 326; the second telescopic drive component 323 is mounted on the rotary platform of the rotary component via the mounting base 326. The mounting base 326 improves the installation stability of the first multi-stage telescopic structure.

[0083] Preferably, the second telescopic drive component 323 is a hydraulic cylinder. Hydraulic cylinders are low in cost and provide more stable and reliable load-bearing capacity under heavy loads.

[0084] In some embodiments, the photovoltaic energy storage mechanism includes two solar photovoltaic components 100; the two solar photovoltaic components 100 are symmetrically arranged on the support component 300. Increasing the number of solar photovoltaic components 100 can improve power generation efficiency. By symmetrically arranging the two solar photovoltaic components 100 on the support component 300, the installation stability of the photovoltaic energy storage device can be improved.

[0085] A specific embodiment of the second utility model provides a light storage device. This light storage device includes a housing and a light storage mechanism as described in any of the above embodiments; the light storage mechanism is installed in the housing. By installing the light storage mechanism in the housing, the convenience of transportation can be further improved.

[0086] Furthermore, the housing has an opening; the end of the telescopic support assembly 320 furthest from the installation end is installed in the housing, and the telescopic support assembly 320 is used to drive the solar photovoltaic component 100 in and out of the housing through the opening. By setting the telescopic support assembly 320, when the solar photovoltaic component 100 needs to be used, the telescopic support assembly 320 can drive the solar photovoltaic component 100 to extend along its own telescopic direction, causing the solar photovoltaic component 100 to leave the housing through the opening. In this way, the solar photovoltaic component 100 is pushed out of the housing and exposed to sunlight, achieving photoelectric conversion. When it is necessary to move the solar photovoltaic component 100 to the next working location, the telescopic support assembly 320 retracts along its own telescopic direction, causing the solar photovoltaic component 100 located outside the housing to return to the housing through the opening. Then, the housing is used to transport the solar photovoltaic component 100 to the next working location. Obviously, this embodiment avoids repeatedly moving the solar photovoltaic component 100 in and out of the housing, eliminating the need for disassembly and assembly of the solar photovoltaic component 100, thus solving the problem of low disassembly and assembly efficiency in medium and large-sized photovoltaic energy storage devices in the prior art. The telescopic support assembly 320 serves as a support for the solar photovoltaic component 100. It eliminates the need for a dedicated mounting bracket for the solar photovoltaic component 100 and eliminates the need to install the solar photovoltaic component 100 and the mounting bracket on the ground. This solves the problem of large floor space required for the installation of the solar photovoltaic component 100 and the mounting bracket on the ground in the prior art.

[0087] Preferably, the container is a shipping container.
