Description

Technical Field

[0001] This utility model relates generally to the technical field of photovoltaic power generation, and more specifically to a self-powered drive device. Background Technology

[0002] The automatic telescopic system of photovoltaic (PV) panels in a PV container requires an electric motor to drive the telescopic mechanism. Each PV container must be equipped with at least one electric motor. Current motor handling presents two problems: first, if left on-site for subsequent retraction, long-term idleness leads to low resource utilization; second, if disassembled and transferred to other containers for reuse, the motors, often located beneath the PV panels, require manual disassembly and reassembly, which is cumbersome and prone to damage, significantly increasing labor and maintenance costs. Furthermore, the system requires supporting power supply equipment and cable laying. However, PV deployment scenarios are often in open areas (such as deserts), and due to geographical constraints, power lines need to be laid over long distances and meet high protection standards, making construction difficult and time-consuming, and failing to meet the needs of rapid on-site deployment of PV containers.

[0003] Therefore, there is a need to provide a self-powered drive device to at least partially solve the above problems. Utility Model Content

[0086] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0087] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art.

[0088] It should be understood that the terminology used herein is intended only to describe particular embodiments and is not intended to limit the scope of the invention. The singular forms “a,” “an,” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. When the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0089] The ordinal numbers such as "first" and "second" used in this utility model are merely identifiers and do not have any other meaning, such as a specific order. Furthermore, for example, the term "first component" does not imply the existence of a "second component," and the term "second component" does not imply the existence of a "first component." It should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," and similar expressions used in this utility model are for illustrative purposes only and are not intended to be limiting.

[0090] The terms “center,” “parallel,” “perpendicular,” “aligned,” and “symmetrical” used in this invention do not have to be precise, but can include typical engineering tolerances.

[0091] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0092] The photovoltaic panels of outdoor photovoltaic containers automatically unfold and retract, requiring an electric motor to drive the extension and retraction of the photovoltaic panels. Each photovoltaic container needs to be equipped with at least one electric motor. After the photovoltaic panels are unfolded, there are two ways to handle the electric motor: (1) leave it on site for subsequent use when the photovoltaic panels are retracted, which has low utilization and wastes resources; (2) disassemble it for continued use. At this time, the photovoltaic panels have already been unfolded, and if the electric motor is located under the photovoltaic panels, disassembly is cumbersome. The subsequent reinstallation after the photovoltaic panels are retracted will cause repeated waste of manpower. In addition, outdoor power supply requires supporting power supply equipment and cable laying. The location where photovoltaics need to be installed is an open area, which places high demands on the on-site installation conditions and is not conducive to rapid on-site installation.

[0093] To at least partially solve the aforementioned technical problems, this utility model provides a self-powered drive device. The self-powered drive device provides driving power for the automatic deployment and retraction of the photovoltaic panel modules of a photovoltaic container, and provides power for the opening and closing of the hatches. See below for reference. Figures 1 to 9 The example shown provides a detailed description of a self-powered drive device 20 according to an embodiment of the present invention.

[0094] Figure 1 and Figure 2 A schematic diagram illustrating the self-powered drive device 20 of an embodiment of the present invention in use with a photovoltaic container 10 is shown. Figure 1 In the middle, the self-powered drive unit 20 is not connected to the photovoltaic container 10. Figure 2 In this configuration, a self-powered drive unit 20 is connected to the photovoltaic container 10. The photovoltaic container 10 includes a container 100 and photovoltaic panel assemblies 120 and a retraction drive assembly 140 located inside the container 100. The retraction drive assembly 140 is connected to the photovoltaic panel assemblies 120. The retraction drive assembly 140 is adapted to transmit power that causes the photovoltaic panel assemblies 120 to unfold and fold. The retraction drive assembly 140 includes a drive connection portion 145a. The drive connection portion 145a is located at the end or side of the container 100.

[0095] See Figures 3 to 9 According to an embodiment of the present invention, the self-powered drive device 20 includes a mobile bearing component 200, a power supply component 250, and a motor 260.

[0096] The bottom of the mobile support assembly 200 is provided with multiple wheel members 210 suitable for travel. A power supply assembly 250 is disposed on the mobile support assembly 200. An electric motor 260 is detachably disposed on the mobile support assembly 200. The electric motor 260 is adapted to be detachably connected to the drive connection portion 145a to provide power to the take-up and take-down transmission assembly 140. The electric motor 260 is electrically connected to the power supply assembly 250.

[0097] In use, by pushing or pulling the movable support component 200, the movable support component 200 can be moved, thereby transferring the positions of the power supply component 250 and the motor 260, and thus transferring the power supply component 250 and the motor 260 to the photovoltaic container 10 where the photovoltaic panel component 120 needs to be unfolded or folded, or to a position suitable for storing or transporting the self-powered drive device 20.

[0098] According to an embodiment of the present invention, the self-powered drive device 20 integrates the power supply component 250 and the motor 260 into the movable support component 200, allowing for flexible relocation using the movable support component 200. When the motor 260 is needed, it is removed and connected to the drive connection part 145a, thereby enabling the photovoltaic panel assembly 120 to be unfolded and folded. After the unfolding or folding operation of the photovoltaic panel assembly 120 is completed, the motor 260 is placed on the movable support component 200, allowing it to be conveniently moved to the next location of the photovoltaic container 10 where the motor 260 is needed, or to a corresponding storage location. This approach simplifies the structure and reduces the cost of the photovoltaic container 10, while also addressing the low resource utilization caused by equipping each photovoltaic container 10 with a motor 260. Furthermore, the connection between the motor 260 and the photovoltaic container 10 can be completed externally, allowing for greater flexibility and ease of installation and removal of the motor 260. This resolves issues in related technologies, such as cumbersome installation and removal of the motor 260 shaft assembly, repeated disassembly and reassembly causing equipment damage, and increased labor and maintenance costs. Moreover, the power supply component 250 can power the motor 260, eliminating the need for additional power supply equipment and long-distance cable laying, thus reducing construction difficulty and shortening the construction period, and meeting the need for rapid on-site installation.

[0099] Optionally, the power supply component 250 is a battery component such as a lithium battery.

[0100] See Figures 3 to 8In some embodiments, the mobile support assembly 200 further includes a seat member 220 and a housing member 230. The bottom of the seat member 220 is connected to the wheel member 210. The housing member 230 is located above and connected to the seat member 220. A first receiving cavity 231 is formed inside the housing member 230. The housing member 230 includes a removable first cover plate 232. The first cover plate 232 is arranged correspondingly to the first receiving cavity 231. The power supply assembly 250 is located in the first receiving cavity 231. The motor 260 is located outside the housing member 230 and is detachably disposed on the top of the housing member 230. With the first cover plate 232 removed, the power supply assembly 250 can be inserted or removed. By arranging the power supply assembly 250 in the first receiving cavity 231, the housing member 230 can protect the power supply assembly 250.

[0101] Optionally, there may be multiple wheel components 210. The multiple wheel components 210 are distributed at intervals along the circumference of the seat component 220.

[0102] For example, the outer contour of the seat member 220 is square. There are four wheel members 210. The four wheel members 210 are located at the four corners of the seat member 220.

[0103] Optionally, the wheel component 210 is a caster wheel. When there are multiple wheel components 210, at least some of the wheel components 210 are caster wheels with a self-locking structure. Caster wheels facilitate the movement of the self-powered drive device 20.

[0104] For example, the seat member 220 includes a base frame and a support plate. The support plate is fixed to the top surface of the base frame. The shell member 230 can be a chassis, cabinet, or other structure.

[0105] See Figures 3 to 6 ,as well as Figure 8 In some embodiments, the mobile support assembly 200 further includes a motor housing member 240. The motor housing member 240 is connected to the top of the housing member 230. The motor housing member 240 has an upward-opening housing slot 241. The motor 260 is located in the housing slot 241. By providing the motor housing member 240 on the top of the housing member 230, it can be used to accommodate the motor assembly, thereby helping to ensure that the motor 260 can be more reliably placed in the mobile support assembly 200.

[0106] Optionally, the motor storage component 240 is a box-shaped part with a hollow structure. For example, the motor storage component 240 is a metal basket.

[0107] See Figure 5 and Figure 9Furthermore, the self-powered drive device 20 also includes a frequency converter 309, a power conversion component 280, and an electrical protection component 308. The motor 260 is electrically connected to the power supply component 250 sequentially via the frequency converter 309, the power conversion component 280, and the electrical protection component 308. The frequency converter 309, the power conversion component 280, and the electrical protection component 308 are all housed in the first receiving cavity 231. After the power supply component 250 and the power conversion component 280 are connected, the power conversion component 280 can convert the DC power from the power supply component 250 into AC power. After the power conversion component 280 is wired to the electrical protection component 308, it outputs power to the frequency converter 309. The motor cable 371 passes through a through-hole in the housing component 230 to reach the outside of the housing component 230 and is wired to the motor 260. The motor 260 and its cable are placed in the receiving slot 241 of the motor receiving component 240. To prevent the motor 260 from shaking or moving, it can be secured within the motor receiving component 240 using straps. The motor cable 371 is sealed to the housing component 230 through a through-hole via the waterproof protective coil 372, such as... Figure 8 As shown. The power supply assembly 250 and the power conversion assembly 280 can be designed for drawer-type installation, allowing for direct removal for repair or replacement in case of problems. The electrical protection assembly 308 can utilize electrical components such as air switches to provide safety protection for the circuit.

[0108] See Figure 3 Optionally, the self-powered drive unit 20 also includes a motor cable reel 373. The motor cable reel 373 is rotatably mounted into a storage slot 241 of the motor storage member 240. The motor cable reel 373 is used to wind the motor cable 371, thereby adapting it for winding and unwinding the motor cable 371.

[0109] The power conversion component 280 can also be referred to as a power conversion system (PCS). A power conversion system is a bidirectional power conversion device capable of converting energy between direct current (DC) and alternating current (AC), and supporting charging and discharging operations between the battery and the power grid. Its core functions include:

[0110] (1) Bidirectional energy conversion: In grid-connected mode, the PCS converts the DC power from the battery into AC power and outputs it to the grid; in off-grid mode, it converts the AC power from the grid into DC power and stores it in the battery.

[0111] (2) Grid interaction management: Supports "grid-following" and "grid-forming" modes. The former achieves energy transmission by matching grid frequency and phase, while the latter actively adjusts grid parameters to maintain stability.

[0112] (3) Responsible for battery charging and discharging control, power distribution and energy optimization.

[0113] See Figure 3 , Figure 5 as well as Figure 6 In some embodiments, the housing member 230 includes a pair of first cover plates 232. The pair of first cover plates 232 are located at both ends of the housing member 230 along the left-right direction Dlr of the seat member 220. At least one of the pair of first cover plates 232 is provided with a vent 232a. The self-powered drive device 20 also includes a fan 271, a thermostat 272, and a power conversion assembly 280. At least one of the pair of first cover plates 232 is connected to the fan 271. The fan 271 is connected to the surface of the first cover plate 232 facing the first receiving cavity 231. The fan 271 is electrically connected to the power supply assembly 250 in sequence via the thermostat 272 and the power conversion assembly 280. The thermostat 272 and the power conversion assembly 280 are located in the first receiving cavity 231. The thermostat 272 is adapted to turn on when the ambient temperature rises to a set value and to turn off when the ambient temperature falls below a set value. The power conversion assembly 280 is used to convert the direct current (DC) power from the power supply assembly 250 into alternating current (AC). In operation, when the temperature inside the first cavity 231 rises to (or exceeds) a set value, the thermostat 272 connects the circuit consisting of the power supply component 250, the power conversion component 280, and the fan 271, thereby causing the fan 271 to operate and exchange air between the first cavity 231 and the outside air, achieving the purpose of cooling the electrical equipment such as the power supply component 250 inside the first cavity 231. When the temperature inside the first cavity 231 drops below the set value, the thermostat 272 disconnects the circuit consisting of the power supply component 250, the power conversion component 280, and the fan 271, thereby causing the fan 271 to stop.

[0114] The thermostat 272 can be understood as a switching device that is triggered by temperature changes.

[0115] Continue reading Figure 3 , Figure 5 as well as Figure 6 Furthermore, the first receiving cavity 231 has a first cover plate 232 on both sides along the left-right direction Dlr. The first cover plate 232 is installed by overlapping with the main sheet metal of the shell component 230 or by fasteners such as bolts, serving a waterproof function. One side of the first cover plate 232 is provided with air inlet louvers to form a ventilation section 232a, and the other side of the first cover plate 232 is equipped with multiple sets of fans 271. The fans 271 correspond to the heat dissipation holes of the power conversion component 280 and the power supply component 250.

[0116] In some embodiments, see Figure 1 and Figure 2The container 100 includes a hatch 104 and an electric drive assembly (not shown). The hatch 104 is rotatably disposed at one end of the container 100 in the width direction D2, about a rotation axis AX, between an open position and a closed position. The rotation axis AX is located at the top of the container 100 and parallel to the length direction D1 of the container 100. The electric drive assembly is connected to the hatch 104. The electric drive assembly is used to drive the hatch 104 between the open and closed positions. The electric drive assembly includes a first power supply connector 191.

[0117] See Figures 3 to 6 The self-powered drive unit 20 also includes a power cable assembly 290. The power cable assembly 290 includes a power cable 291 and a second power connector 292. One end of the power cable 291 is electrically connected to the power supply assembly 250. The other end is connected to the second power connector 292, so that the second power connector 292 is electrically connected to the power supply assembly 250. The second power connector 292 is adapted to be detachably connected to the first power connector 191.

[0118] In use, by connecting the second power supply connector 292 of the power supply cable component 290 to the first power supply connector 191 of the electric drive component, the power supply component 250 can supply power to the electric drive component, thereby causing the hatch 104 to move to the open or closed position when the power supply component 250 supplies power to the electric drive component, thus realizing the opening or closing of the hatch 104.

[0119] Optionally, the electric drive assembly is an electric actuator. The electric actuator has a telescopic rod. Extending the telescopic rod corresponds to moving the hatch 104 to the open position, and retracting the telescopic rod corresponds to moving the hatch 104 to the closed position.

[0120] Optionally, the first power connector 191 is a power socket. The second power connector 292 is a power plug. The power plug is plugged into the power socket.

[0121] Optionally, when the hatch 104 is in the closed position, a portion of the hatch 104 is located at one end of the container 100 along the width direction D2, and another portion is located at the top of the container 100 along the height direction D3. The dimension of the portion of the hatch 104 corresponding to the top of the container 100 along the width direction D2 is smaller than the width of the container 100.

[0122] Continue reading Figures 3 to 6In some embodiments, the self-powered drive device 20 further includes a first cable reel 301 and a first operating handle 302. The first cable reel 301 is rotatably disposed above the seat member 220. A power cable 291 is wound around the first cable reel 301. The first operating handle 302 is connected to the first cable reel 301. The first operating handle 302 is adapted to be operated to rotate the first cable reel 301. By providing the first cable reel 301, the power cable 291 can be wound. By providing the first operating handle 302, it is convenient for the user to operate and rotate the first cable reel 301 to wind up the power cable 291. When it is necessary to release the power cable 291, the user pulls one end of the second power connector 292, and the first cable reel 301 will adaptively rotate and release the power cable 291, lengthening the released power cable 291, ultimately allowing the second power connector 292 to connect to the first power connector 191.

[0123] Alternatively, the movable support assembly 200 may also be configured to automatically wind up the first cable reel 301. For example, the automatic winding of the first cable reel 301 may be achieved by a spiral spring.

[0124] Alternatively, the first cable reel 301 can be an existing cable reel. The first operating handle 302 can be configured as a foldable handle.

[0125] exist Figure 4 In the example shown, the first cable reel 301 is rotatably disposed at one end of the housing member 230 along the left-right direction Dlr of the seat member 220 about a first axis AX1. The first axis AX1 is parallel to the left-right direction Dlr.

[0126] In other examples, the first cable reel 301 may be located at one end of the housing member 230 along the front-rear direction Dfr of the seat member 220. The direction of the first axis AX1 may be parallel to the front-rear direction Dfr.

[0127] See Figure 3 and Figure 5 In some embodiments, a first groove 233 is formed in a recess on a portion of the outer surface of the housing member 230. The first groove 233 is adapted to accommodate the first cable reel 301. By forming the first groove 233 in the recess of the housing member 230, the first cable reel 301 can be accommodated, thereby reducing the space occupied by the first cable reel 301 on the external space of the housing member 230, thereby improving the structural compactness of the movable bearing assembly 200 and realizing the miniaturization of the self-powered drive device 20.

[0128] See Figure 3 , Figure 4 ,as well as Figure 6In some embodiments, the self-powered drive device 20 further includes a charging cable 310 and a power conversion assembly 280. The charging cable 310 includes a charging cable 311 and a charging connector 312.

The charging connector 312 is adapted to be connected to AC power. The power conversion assembly 280 is used to convert AC power from AC power to DC power. By providing the charging cable 310 and the power conversion assembly 280, the power supply assembly 250 can be charged while the charging connector 312 of the charging cable 310 is connected to AC power. That is, when the power supply assembly 250 is low on power and needs charging, charging can be achieved by connecting the charging connector 312 of the charging cable 310 to an electrical connector connected to AC power. When the power supply component 250 is fully charged or has sufficient power, it can supply power to the motor 260 to drive the photovoltaic panel component 120 to unfold and fold, and supply power to the electric drive component when the first power supply connector 191 is connected to the second power supply connector 292 to open or close the door 104.

[0129] Optionally, the charging connector 312 is a charging plug.

[0130] Continue reading Figure 3 , Figure 4 ,as well as Figure 6 In some embodiments, the movable support assembly 200 further includes a seat member 220 and a housing member 230. The bottom of the seat member 220 is connected to the wheel member 210. The housing member 230 is located above and connected to the seat member 220. The self-powered drive device 20 also includes a second cable reel 303 and a second operating handle 304. The second cable reel 303 is rotatably disposed above the seat member 220. A charging cable 311 is wound around the second cable reel 303. The second operating handle 304 is connected to the second cable reel 303. The second operating handle 304 is adapted to be operated to rotate the second cable reel 303.

[0131] The charging cable 311 can be wound around a second cable reel 303. A second operating handle 304 allows the user to easily rotate the second cable reel 303 to wind up the charging cable 311. When it is necessary to release the charging cable 311, the user pulls one end of the charging connector 312, and the second cable reel 303 will adaptively rotate and release the charging cable 311, lengthening the released cable 311 and ultimately allowing the charging connector 312 to connect to mains power.

[0132] Alternatively, the movable support assembly 200 may also be configured to automatically wind up the second cable reel 303. For example, the automatic winding of the second cable reel 303 may be achieved by a spiral spring.

[0133] Alternatively, the second cable reel 303 can be an existing cable reel. The second operating handle 304 can be configured as a foldable handle.

[0134] exist Figure 4 In the example shown, the second cable reel 303 is rotatably disposed at the other end of the housing member 230 along the left-right direction Dlr of the seat member 220 about the second axis AX2. The second axis AX2 is parallel to the left-right direction Dlr. In the case of having the first cable reel 301 described above, the first cable reel 301 and the second cable reel 303 are located at the two ends of the housing member 230 along the left-right direction Dlr.

[0135] In other examples, the second cable reel 303 may be located at one end of the housing member 230 along the front-rear direction Dfr of the seat member 220. The direction of the second axis AX2 may be parallel to the front-rear direction Dfr.

[0136] See Figure 3 In some embodiments, a second groove 234 is formed in a partial recess on the outer surface of the housing member 230. The second groove 234 is adapted to accommodate the second cable reel 303. By forming the second groove 234 in the recess of the housing member 230, the second cable reel 303 can be accommodated, thereby reducing the space occupied by the second cable reel 303 on the external space of the housing member 230, thereby improving the structural compactness of the mobile support assembly 200 and realizing the miniaturization of the self-powered drive device 20.

[0137] See also Figure 3 , Figure 4 ,as well as Figure 6 In some embodiments, the shell member 230 includes a panel portion 239. The panel portion 239 is located on the upper part of the shell member 230. The self-powered drive device 20 also includes a panel control assembly 320. The panel control assembly 320 is connected to the panel portion 239. The panel control assembly 320 is electrically connected between the motor 260 and the power supply assembly 250 and between the second power supply connector 292. The panel control assembly 320 includes a first motor controller 321 and a first door controller 322. The first motor controller 321 is used to control the operating state of the motor 260. The first door controller 322 is used to control the state of the electrical energy output from the second power supply connector 292. In this embodiment, the first motor controller 321 is used to control the forward and reverse rotation of the motor 260, thereby realizing the unfolding and folding of the photovoltaic panel assembly 120. The first door controller 322 is used to control the electric drive assembly, causing the door 104 to open or close.

[0138] Furthermore, the self-powered drive unit 20 includes a forward / reverse switching circuit for switching the forward and reverse rotation of the motor 260. A first motor controller 321 is electrically connected to the forward / reverse switching circuit to select between a power supply circuit suitable for controlling the unfolding of the photovoltaic panel assembly and a power supply circuit suitable for controlling the folding of the photovoltaic panel assembly 120. The first motor controller 321 includes a first unfold switch and a first folding switch. When the first unfold switch is triggered, the motor 260 rotates forward (or reverse), correspondingly unfolding the photovoltaic panel assembly 120. When the first folding switch is triggered, the motor 260 rotates in reverse (or forward), thereby folding the photovoltaic panel assembly 120. Accordingly, the panel control assembly 320 includes a telescopic motion switching circuit for switching the extension / retraction action of the electric drive assembly to select between a power supply circuit suitable for controlling the movement of the hatch 104 to the open position and a power supply circuit suitable for controlling the movement of the hatch 104 to the closed position. A first hatch controller 322 is electrically connected to the telescopic motion switching circuit. The first hatch controller 322 includes a first open switch and a first close switch. When the first opening switch is triggered, the hatch 104 is opened; when the first closing switch is triggered, the hatch 104 is closed.

[0139] Optionally, the first unfolding switch, the first folding switch, the first opening switch, and the first closing switch mentioned above can be switch forms such as push button switches or touch switches, and there is no limitation on them here.

[0140] See Figure 4 and Figure 9 In some embodiments, to prevent the panel control component 320 from failing to retract the photovoltaic panel component 120 and open and close the door 104, the self-powered drive device 20 also includes a backup control component 330.

[0141] The backup control component 330 is electrically connected between the motor 260 and the power supply component 250, and between the second power supply connector 292. The backup control component 330 includes a second motor controller (not shown) and a second door controller (not shown). The second motor controller controls the operating state of the motor 260. The second door controller controls the state of the electrical energy output from the second power supply connector 292. The housing member 230 forms a second receiving cavity 235. The second receiving cavity 235 is spaced apart from the first receiving cavity 231. The housing member 230 includes a second cover plate 236 corresponding to the second receiving cavity 235. The second receiving cavity 235 is adapted to accommodate the backup control component 330. In this embodiment, when the panel control component 320 completely fails or partially fails in its control function, the backup control component 330 performs the corresponding function. The second motor controller controls the forward and reverse rotation of the motor 260, thereby enabling the photovoltaic panel assembly 120 to unfold and fold. The second door controller controls the electric drive component, causing the door 104 to open or close. By providing a second receiving cavity 235, the backup control component 330 can be easily stored, thereby reducing the space occupied by the backup control component 330 and also protecting it. When the backup control component 330 needs to be used, the second receiving cavity 235 can be opened by opening the second cover 236 to remove the backup control component 330.

[0142] Optionally, the backup control component 330 is electrically connected to the power supply component 250 via a cable passing through the second receiving cavity 235 and the first receiving cavity 231 via a power conversion component 280. This reduces the space occupied by the cable. With the backup control component 330 housed in the second receiving cavity 235, the second receiving cavity 235 is adapted to accommodate a section of cable connected to the backup control component 330, which is sufficient to adaptively extend to the required length when the backup control component 330 is retrieved.

[0143] Furthermore, the second motor controller is electrically connected to the aforementioned forward / reverse switching circuit to select between a power supply circuit suitable for controlling the unfolding of the photovoltaic panel assembly and a power supply circuit suitable for controlling the folding of the photovoltaic panel assembly 120. The second motor controller includes a second unfold switch and a second folding switch. When the second unfold switch is triggered, the motor 260 rotates forward (or reverses), correspondingly unfolding the photovoltaic panel assembly 120. When the second folding switch is triggered, the motor 260 rotates in reverse (or forward), thereby folding the photovoltaic panel assembly 120. Accordingly, the panel control assembly 320 includes a switching circuit for switching the telescopic action of the electric drive assembly to select between a power supply circuit suitable for controlling the movement of the hatch 104 to the open position and a power supply circuit suitable for controlling the movement of the hatch 104 to the closed position. The first hatch controller 322 is electrically connected to the telescopic action switching circuit. The second hatch controller includes a second open switch and a second close switch. When the second open switch is triggered, the hatch 104 is opened; when the second close switch is triggered, the hatch 104 is closed.

[0144] Optionally, the aforementioned second unfolding switch, second folding switch, second opening switch, and second closing switch can be switch forms such as push button switches or touch switches, and there is no limitation on them here.

[0145] See Figure 3 , Figure 4 ,as well as Figure 6 In some embodiments, the self-powered drive device 20 further includes a power conversion assembly 280 and a power socket 340. The power socket 340 is electrically connected to the power supply assembly 250 via the power conversion assembly 280. The power conversion assembly 280 converts the direct current output from the power supply assembly 250 into alternating current (AC) power, the same as AC mains power. The power socket 340 provides AC mains power. The power socket 340 provides an interface for power supply to on-site electrical equipment or other electrical devices. Here, AC mains power can be understood as 220V AC power.

[0146] Optionally, the number of power outlets 340 can be one, two, or more. There is no limitation here.

[0147] Continue reading Figure 3 , Figure 4 ,as well as Figure 6Optionally, the mobile support assembly 200 also includes a seat member 220 and a housing member 230. The bottom of the seat member 220 is connected to the wheel member 210. The housing member 230 is located above and connected to the seat member 220. The housing member 230 includes a panel portion 239. The panel portion 239 is located on the upper part of the housing member 230. A power socket 340 is provided on the panel portion 239. By providing the power socket 340 on the panel portion 239, the layout of the electrical structure can be optimized, making it easier for the user to use.

[0148] See Figure 3 , Figure 4 ,as well as Figure 6 Furthermore, the self-powered drive device 20 also includes a lighting fixture 350. The lighting fixture 350 includes a lamp body 352, a flexible rod 353, and a lighting plug 351. The lamp body 352 is connected to the lighting plug 351 via the flexible rod 353. The flexible rod 353 is configured to be moldable. The lamp body 352 is electrically connected to the lighting plug 351. The lighting plug 351 is adapted to be plugged into a power socket 340. The housing member 230 forms a third receiving cavity 237. The third receiving cavity 237 is spaced apart from the first receiving cavity 231. The housing member 230 includes a third cover plate 238 corresponding to the third receiving cavity 237. The third receiving cavity 237 is adapted to accommodate the lighting fixture 350. By providing the lighting fixture 350, it is convenient to provide lighting conditions in low-light environments such as at night. The lighting fixture 350 draws power from the power socket 340 via a lighting plug 351, which helps reduce the amount of cable used and facilitates the fixing of the lighting fixture 350 by connecting the lighting plug 351 to the socket. The third receiving cavity 237 facilitates the storage and protection of the lighting fixture 350 when not in use. Furthermore, since the flexible rod 353 is malleable, it can be bent to reduce space occupation when needed for storage, thus reducing the required size of the third receiving cavity 237. In use, the flexible rod 353 can also be shaped to change the height and orientation of the lamp body 352, thereby enabling arbitrary switching of the lighting angle.

[0149] Continue reading Figure 3 , Figure 4 ,as well as Figure 6In some embodiments, the housing member 230 includes a panel portion 239. The panel portion 239 is located on the upper part of the housing member 230. The self-powered drive device 20 also includes a power conversion assembly 280 and a display assembly 305. The display assembly 305 is connected to the panel portion 239. The display assembly 305 is electrically connected to the power supply assembly 250 via the power conversion assembly 280. The display assembly 305 is used to display the electrical parameters of the power supply assembly 250. The electrical parameters include remaining power, voltage, and current. The power conversion assembly 280 is used to convert the direct current (DC) power of the power supply assembly 250 into alternating current (AC). By providing the display assembly 305 on the panel portion 239 to display electrical parameters of the power supply assembly 250, such as remaining power, the user can obtain timely and intuitive information to determine whether the power supply assembly 250 needs to be charged.

[0150] Alternatively, the display component 305 here may be a type of display in the prior art, such as an LCD or a touch screen.

[0151] See Figures 3 to 6 as well as Figure 9 In some embodiments, the self-powered drive unit 20 further includes an emergency stop switch 306, a power conversion component 280, a main switch 307, a panel control component 320, a backup control component 330, a socket, a thermostat 272, a fan 271, and a display component 305. The power supply component 250 is electrically connected to the main switch 307 via the emergency stop switch 306 and the power conversion component 280. The panel control component 320 and the socket are both electrically connected to the main switch 307. The fan 271 is electrically connected to the power conversion component 280 via the thermostat 272. The display component 305 is electrically connected to the power conversion component 280. The power conversion component 280 converts the direct current (DC) power from the power supply component 250 into alternating current (AC). When the emergency stop switch 306 is closed (on) and the main switch 307 is open, the panel control component 320 cannot control the power supply to the motor 260 or the second power connector 292. When the main switch 307 is closed (on), the panel control component 320 can control the operating status of the motor 260, and can also control the operating status of the electric drive component when the second power supply connector 292 is connected to the first power supply connector 191. At this time, regardless of whether the main switch 307 is on or off, the display component 305 always maintains normal display function. The operation of the fan 271 is only controlled by the thermostat 272. At this time, the power socket 340 is not powered. When the emergency stop switch 306 is off, the panel control component 320, the power socket 340, the fan 271, and the display component 305 all malfunction.

[0152] See Figures 3 to 8In some embodiments, the movable support assembly 200 further includes a push-pull member 360. The push-pull member 360 is connected to one end of the base member 220 and the housing member 230 in the front-rear direction Dfr. The push-pull member 360 extends along the vertical direction Dv of the base member 220. A grip portion 361 for holding is formed at the top of the push-pull member 360. By providing the push-pull member 360, it is convenient for a user to move the entire self-powered drive unit 20 by holding the grip portion 361.

[0153] Alternatively, the push-pull member 360 can be a push-pull rod.

[0154] Preferably, the push-pull rod can be a telescopic rod, similar to a suitcase handle. It can be pulled upwards to better suit the user's exertion posture when in use, and retracted downwards to reduce space occupation when not in use. This makes operation more flexible and convenient. The telescopic rod's extension and length adjustment are achieved via buttons and latches.

[0155] See Figures 3 to 6 In the embodiments of this application, the push-pull rod is located on one side of the self-powered drive device 20 along the front-rear direction Dfr. The second receiving cavity 235 and the third receiving cavity 237 are located on the other side of the self-powered drive device 20 along the front-rear direction Dfr. A pair of first cover plates 232 are located on both sides of the self-powered drive device 20 along the left-right direction Dlr. The first cable reel 301 and the second cable reel 303 are located on both sides of the self-powered drive device 20 along the left-right direction Dlr. In the front-rear direction Dfr, the first cable reel 301 and the second cable reel 303 are located at the end of the first cover plate 232 opposite to the push-pull rod. The panel control assembly 320, the power socket 340, and the display assembly 305 are all located on the panel portion 239. The panel portion 239 is located at the end of the housing member 230 opposite to the push-pull rod along the front-rear direction Dfr. The panel portion 239 is inclined to the vertical direction Dv of the seat member 220 to facilitate observation and operation by the user in front of the power-powered drive device.

[0156] See Figure 1 and Figure 2In the application scenario of this utility model, the photovoltaic panel assembly 120 of the photovoltaic container 10 includes multiple photovoltaic panel components 121 cascaded together. Each photovoltaic panel component 121 includes a photovoltaic panel and a mounting frame for mounting the photovoltaic panel. The connection between two adjacent photovoltaic panel components 121 is achieved by hinged mounting frames. When the photovoltaic panel assembly 120 is unfolded, it is located outside the container 100, and any four adjacent photovoltaic panel components 121 form a shape similar to an M or W. When the photovoltaic panel assembly 120 is folded, all the photovoltaic panel components 121 are stacked and can be stored inside the container 100. The photovoltaic container 10 also includes a track assembly 130, which is laid on the outside of the container 100 after the photovoltaic container 10 is deployed at the place of use. The photovoltaic panel assembly 120 slides relative to the track assembly 130 along the guide direction of the track assembly 130, thereby unfolding or folding. During the transportation of the photovoltaic container 10, the track assembly 130 is disassembled into independent parts and stored inside the container 100, for example, below the photovoltaic panel assembly 120. Part of the take-up and drop-off drive assembly 140 is located inside the container 100, while another part is detachable and can be deployed outside the container 100. The take-up and drop-off drive assembly 140 can be connected to a drive shaft 145 of the motor 260, a chain drive component 141, and a gear drive assembly that drives the drive shaft 145 and the chain drive component 141. After on-site deployment, the chain drive component 141 is located outside the container 100 and arranged side-by-side with the track assembly 130. The chain drive component 141 includes a chain. The chain engages with a toothed plate at the lower part of the photovoltaic panel assembly 121 to be driven by the moving chain, thereby obtaining the power to move along the guide direction of the track assembly 130. The photovoltaic container 10 may also include at least one set of power output interfaces 192 located at the end of the container 100. The power output interface 192 is used for the electricity generated by the photovoltaic power generation of the photovoltaic panel module 120. The power output interface 192 can be connected to the energy storage container 100 or connected to the power grid.

[0157] The self-powered drive device 20 of this utility model can provide electrical energy and a corresponding controller for opening the hatch 104 of the photovoltaic container 10, and provide a motor 260 and a corresponding controller for unfolding and retracting the photovoltaic panel assembly 120.

[0158] See Figures 1 to 8 One method of using the self-powered drive device 20 of this utility model is as follows:

[0159] After moving the self-powered drive unit 20 to the photovoltaic container 10 to be deployed, remove the motor 260 and connect the motor 260 to the drive shaft 145 of the photovoltaic container 10 (e.g., spline connection). Secure the mounting flange or mounting base of the motor 260 to the container 100 with bolts. Then, rotate the first cable reel 301 to release the power cable 291 and connect the second power connector 292 to the first power connector 191 at the container 100. Then, open the hatch 104 of the container 100 using the control panel assembly 320. After the track assembly 130 is laid, use the control panel assembly 320 to unfold the photovoltaic panel assembly 120 along the track assembly 130. After completing the above operations, turn off the main switch 307, remove the bolts between the motor 260 and the container 100, place the motor 260 into the motor storage component 240, and secure it with straps. Furthermore, the second power supply connector 292 is detached from the photovoltaic container 10, and the power supply cable 291 is wound up by rotating the first cable reel 301. The self-powered drive unit 20 is then moved to the next photovoltaic container 10, and this process is repeated.

[0160] When the photovoltaic container 10 is no longer in use or needs to be moved to another location, the operation method is as follows: First, move the self-powered drive unit 20 to the photovoltaic container 10, remove the motor 260, connect the motor 260 to the drive shaft 145 of the photovoltaic container 10 (e.g., spline connection), and fasten the mounting flange or mounting base of the motor 260 to the container 100 with bolts. Control the photovoltaic panel assembly 320 through the operation panel control component to fold the photovoltaic panel assembly 120 along the track assembly 130. After storing the photovoltaic panel assembly 120 inside the container 100, rotate the first cable reel 301 to release the power supply cable 291, and connect the second power supply connector 292 to the first power supply connector 191 at the container 100. Then, control the container 100 door 104 through the operation panel control component 320. After the above operations are completed, turn off the main switch 307, remove the bolts between the motor 260 and the container 100, put the motor 260 into the motor storage component 240, and secure it with straps. Furthermore, the second power supply connector 292 is detached from the photovoltaic container 10, and the power supply cable 291 is wound up by rotating the first cable reel 301. The self-powered drive unit 20 is then moved to the next photovoltaic container 10, and this process is repeated.

[0161] After the track assembly 130 is laid, the self-powered drive unit 20 is moved to the next photovoltaic container 10, and this operation is repeated.
