Description

Technical Field

[0001] This invention relates to the field of new energy power supply technology, and more specifically to an integrated photovoltaic and energy storage independent power supply device. Background Technology

[0002] Solar photovoltaic (PV) power generation technology has been widely used in outdoor operations, emergency power supply, and power supply in remote areas due to its clean and renewable characteristics. Existing portable PV-storage integrated power supplies typically use fixed installations or simple folding methods for their PV panels. For example, a common design involves fixing the PV panels to the top of a housing, limiting the power generation area to the size of the top surface and thus limiting power output, making it difficult to meet the demands of high loads or fast charging.

[0003] In pursuit of larger power generation areas, solutions have emerged in the market that use multiple independent photovoltaic panels connected by cables and laid out on the ground. While this method offers a large power generation area, it has significant drawbacks: First, the deployment and storage process is cumbersome, requiring manual handling, assembly, and wiring, which is time-consuming and inconvenient; second, it occupies a large area after deployment, making it significantly limited by available space; and third, the photovoltaic panels are separated from the main unit, resulting in a loose structure and poor overall integrity.

[0004] Therefore, how to provide an integrated photovoltaic and energy storage independent power supply device that can increase the effective power generation area while maintaining the integrity of the device, facilitating transportation and storage, and ensuring structural stability and flatness of the photovoltaic array after deployment is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides an integrated photovoltaic and energy storage independent power supply device, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A photovoltaic-storage integrated independent power supply device, comprising: The cabinet has a top-mounted photovoltaic panel fixed to its top surface and a receiving groove provided on its side wall. A photovoltaic module, comprising a main photovoltaic panel and a secondary photovoltaic panel; the main photovoltaic panel is embedded in the receiving groove, and the secondary photovoltaic panel is hinged to the surface of the main photovoltaic panel and can be stacked and stored in the receiving groove with the main photovoltaic panel; A driving mechanism is installed in the receiving slot, and its driving end is hinged to the main photovoltaic panel. The main photovoltaic panel can be raised to the same plane as the top photovoltaic panel under the drive of the driving mechanism, and the secondary photovoltaic panel can be flipped to the same plane as the main photovoltaic panel, so that the main photovoltaic panel, the secondary photovoltaic panel and the top photovoltaic panel together form an extended photovoltaic array.

[0007] Through the above technical solution, this invention discloses an integrated photovoltaic and energy storage independent power supply device. Within a single cabinet, a linkage mechanism of lifting and flipping enables the power generation unit to switch between two states: highly compact storage and large-area high-efficiency power generation. This effectively solves the core contradiction between the small power generation area of ​​traditional photovoltaic and energy storage power supplies and the poor portability and cumbersome operation of separate power panels. This solution ensures that the device is a complete cube during transportation and storage, minimizing its volume. When in use, it can quickly form an integrated extended photovoltaic array, maximizing the power generation capacity per unit storage volume and greatly improving ease of use and environmental adaptability.

[0008] Preferably, in the above-mentioned integrated photovoltaic and energy storage independent power supply device, the edge of the auxiliary photovoltaic panel is hinged to the edge of the main photovoltaic panel via a hinge. Using a hinge to connect the main and auxiliary photovoltaic panels provides a simple, low-cost, reliable rotation, and easy-to-manufacture and assemble implementation scheme, and is one of the most direct and stable technical means to achieve the flipping function of the auxiliary photovoltaic panel.

[0009] Preferably, in the aforementioned integrated photovoltaic and energy storage independent power supply device, the sidewalls of the auxiliary photovoltaic panel and the main photovoltaic panel have hinged links to each other, which are used to maintain stability when the auxiliary photovoltaic panel and the main photovoltaic panel are coplanar. When the auxiliary photovoltaic panel is flipped to be coplanar with the main photovoltaic panel, the linkage mechanism can provide additional locking or support force, effectively enhancing the overall rigidity and wind resistance of the photovoltaic panel plane after unfolding, ensuring the flatness and safety of the power generation surface in complex outdoor environments, and improving the reliability and durability of the product.

[0010] Preferably, in the above-mentioned integrated photovoltaic and energy storage independent power supply device, the four side walls of the cabinet are provided with the receiving slots. By placing the receiving slots on the four side walls of the cabinet, the total area of ​​the expanded photovoltaic array can be maximized. The symmetrically arranged drive mechanism provides a stable lifting force for each main photovoltaic panel, avoiding the jamming, tilting, or uneven force problems that may be caused by single-point drive, ensuring a smooth unfolding process and the overall structural strength after unfolding.

[0011] Preferably, in the above-mentioned integrated photovoltaic and energy storage independent power supply device, the driving mechanism is any one of a hydraulic strut, an electric push rod, or a linear motor.

[0012] Preferably, in the above-mentioned integrated photovoltaic and energy storage independent power supply device, the driving mechanism is a hydraulic strut. The fixed end of the hydraulic strut is installed on the receiving groove, and its telescopic end is hinged to the surface of the main photovoltaic panel away from the secondary photovoltaic panel. The hydraulic strut has the advantages of self-locking, strong load-bearing capacity, and smooth operation. Moreover, this installation method can most effectively transfer the lifting force to the main photovoltaic panel and completely hide the driving mechanism when stored.

[0013] Preferably, in the above-mentioned integrated photovoltaic and energy storage independent power supply device, the main photovoltaic panel and the auxiliary photovoltaic panel are the same size. This makes the unfolded photovoltaic array neat and aesthetically pleasing, and optimizes the calculation and layout of the power generation area. On the other hand, it greatly simplifies the complexity of production, inventory management, and spare parts maintenance, and reduces costs, making it a preferred design for industrial implementation.

[0014] Preferably, in the above-mentioned integrated photovoltaic and energy storage independent power supply device, the auxiliary photovoltaic panel is rotated 180° to be coplanar with the main photovoltaic panel. Quantifying coplanarity as a 180° rotation clarifies the standard action of the auxiliary photovoltaic panel from a fully stacked state to a fully unfolded state.

[0015] Preferably, in the above-mentioned integrated photovoltaic and energy storage independent power supply device, the surface of the auxiliary photovoltaic panel is flush with the outer wall of the cabinet when it is stored. This ensures that the device forms a cube without protrusions or depressions when stored, resulting in a neat appearance, easy stacking and transportation, and less susceptibility to damage. This flush structure also facilitates the installation of sealing strips, improves the dustproof and waterproof rating of the entire cabinet, protects the internal photovoltaic panels and electrical components, and enhances the environmental tolerance of the equipment.

[0016] Preferably, in the aforementioned integrated photovoltaic and energy storage independent power supply device, the cabinet also integrates an energy storage battery, a control circuit, and an inverter module. The cabinet integrates three core electrical modules—energy storage, control, and inverter—forming a fully functional, readily available, and off-grid-compatible independent power supply system.

[0017] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an integrated photovoltaic and energy storage independent power supply device, which has the following beneficial effects: 1. This invention, through a lifting and flipping linkage structure, achieves a rapid and reliable conversion of the power generation unit from a compact storage state to a large-area working state while maintaining the overall height of the device and its cubic storage form. This effectively solves the fundamental contradiction between the power generation area and the storage volume in portable power supplies, allowing a single cabinet to form an extended photovoltaic array composed of a top-mounted photovoltaic panel, multiple main photovoltaic panels, and auxiliary photovoltaic panels after unfolding, thereby maximizing the power generation capacity within a unit storage volume.

[0018] 2. Through optimized structural design, such as symmetrically arranged drive mechanisms, enhanced stability linkages, uniform photovoltaic panel dimensions, and a flush appearance during storage, this invention not only ensures smooth deployment and stable and reliable operation, but also greatly improves the product's environmental adaptability, production convenience, and overall aesthetics. Combined with the internally integrated energy storage and control modules, this device ultimately becomes an independent power supply system that is ready to use, generates electricity efficiently, is easy to carry, and is robust and durable, significantly improving energy security and user experience in outdoor and emergency power supply scenarios.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] See appendix Figure 1As shown, an embodiment of the present invention discloses a photovoltaic-storage integrated independent power supply device, comprising: Cabinet 1, with a top-mounted photovoltaic panel 2 fixed on the top surface of cabinet 1, and a receiving groove 11 opened on the side wall of cabinet 1; The photovoltaic module includes a main photovoltaic panel 3 and a secondary photovoltaic panel 4. The main photovoltaic panel 3 is embedded in the receiving groove 11, and the secondary photovoltaic panel 4 is hinged to the surface of the main photovoltaic panel 3 and can be stacked with the main photovoltaic panel 3 and stored in the receiving groove 11. The drive mechanism 5 is installed in the receiving slot 11, and its drive end is hinged to the main photovoltaic panel 3. The main photovoltaic panel 3 can be raised to the same plane as the top photovoltaic panel 2 under the drive of the drive mechanism 5, and the auxiliary photovoltaic panel 4 can be flipped to be the same plane as the main photovoltaic panel 3, so that the main photovoltaic panel 3, the auxiliary photovoltaic panel 4 and the top photovoltaic panel 2 together form an extended photovoltaic array.

[0024] In some specific embodiments, the edge of the secondary photovoltaic panel 4 is hinged to the edge of the primary photovoltaic panel 3 by a hinge 6; the hinge 6 can be a medium-duty load-bearing hinge made of stainless steel (for example, 80-120mm in length, capable of bearing a panel weight of more than 20kg) to ensure that the secondary photovoltaic panel 4 can be rotated smoothly and will not sag during long-term use.

[0025] More specifically, the sidewalls of the secondary photovoltaic panel 4 and the main photovoltaic panel 3 have hinged connecting rods 7 to each other, which are used to maintain stability when the secondary photovoltaic panel 4 and the main photovoltaic panel 3 are coplanar.

[0026] In some other embodiments, the four side walls of the cabinet 1 are provided with receiving slots 11.

[0027] In a specific embodiment, the drive mechanism 5 is any one of a hydraulic strut, an electric push rod, or a linear motor.

[0028] In a specific example, the drive mechanism 5 is a hydraulic strut. The fixed end of the hydraulic strut is installed on the receiving groove 11, and its telescopic end is hinged to the surface of the main photovoltaic panel 3 away from the secondary photovoltaic panel 4. The hydraulic strut can be a model with a stroke of 400-600mm and a rated thrust in the range of 300-500N to meet the lifting requirements of the main photovoltaic panel 3, and can provide a smooth, self-locking lifting force to ensure that the main photovoltaic panel 3 can stably maintain a horizontal position after being unfolded.

[0029] More specifically, the main photovoltaic panel 3 and the auxiliary photovoltaic panel 4 are the same size.

[0030] In some specific examples, the secondary photovoltaic panel 4 is rotated 180° and is coplanar with the primary photovoltaic panel 3.

[0031] In some other embodiments, the surface of the secondary photovoltaic panel 4 is flush with the outer wall of the cabinet 1 when it is folded up.

[0032] In a specific embodiment, the cabinet 1 also integrates an energy storage battery, a control circuit, and an inverter module; the energy storage battery can be a lithium iron phosphate battery pack, and its capacity can be configured as 2kWh, 5kWh, or 10kWh, etc., depending on the requirements; the inverter module can be adapted to output 220V / 50Hz AC power, with a rated power of 1000W to 3000W; the control circuit includes an MPPT solar charge controller, whose maximum photovoltaic input voltage can reach 100V and charging current can reach 50A.

[0033] The embodiments of the present invention are as follows: In its stored state, such as Figure 1 As shown, the main photovoltaic panel 3 and the secondary photovoltaic panel 4 stacked on top of it are embedded in the receiving groove 11, and the outer surface of the secondary photovoltaic panel 4 is flush with the outer surface of the side wall of the cabinet 1, making the whole device a regular cubic structure, which is convenient for transportation and storage. The energy storage battery, control circuit and inverter module integrated inside the cabinet 1 are in standby mode.

[0034] When power generation is needed, the drive mechanism 5 is activated first. Taking the hydraulic strut as an example, its telescopic end extends, pushing the main photovoltaic panel 3 to rotate outward and upward, thus raising it. Figure 2 and Figure 3 As shown, the main photovoltaic panel 3 is gradually raised from the receiving groove 11 under the drive of the hydraulic strut until its surface is at the same level as the surface of the top photovoltaic panel 2. At this time, the drive mechanism 5 can be self-locked or mechanically limited to maintain the unfolded position.

[0035] Subsequently, as Figure 4 and Figure 5 As shown, the secondary photovoltaic panel 4 can be manually or through an auxiliary mechanism rotated outward around the hinge 6. When the secondary photovoltaic panel 4 is rotated 180°, its surface is completely coplanar with the surface of the main photovoltaic panel 3. At this time, the connecting rod 7 unfolds and locks, providing additional support for the secondary photovoltaic panel 4, enhancing the structural stability of the entire panel and resisting wind loads.

[0036] Ultimately, as Figure 6 As shown, after all the main photovoltaic panels 3 and secondary photovoltaic panels 4 on all sides have completed the above-mentioned unfolding action, they together with the top photovoltaic panel 2 form an extended photovoltaic array.

[0037] The dimensions of cabinet 1 and the specifications of the top-mounted photovoltaic panel 2, main photovoltaic panel 3 and auxiliary photovoltaic panel 4 can be determined according to actual needs.

[0038] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably.
