[0028] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Example 1:

[0030] like Figures 1 to 2 、 Figures 7 to 8 As shown, a portable storage bag with integrated solar energy storage of the present invention includes a bag body 1, a foldable solar panel module 2, and an energy storage power supply module 3. The bag body 1 is provided with a storage space 11 and a power supply space 12. The energy storage power supply module 3 is embedded in the power supply space 12. The solar panel module 2 is arranged on the outside of the bag body 1. The bag body 1 is provided with an interface panel 4 for docking external equipment. The power output end of the solar panel module 2 is connected to the power input end of the energy storage power supply module 3, and the power output end of the energy storage power supply module 3 is connected to the interface panel 4. When stored, the solar panel module 2 is folded and embedded in the bag body 1. When taking power, the solar panel module 2 is unfolded relative to the bag body 1.

[0031] The energy storage power module 3 in the present invention adopts a slim design, and the power space 12 in the bag 1 is also designed as a slim space structure, so that the energy storage power module 3 can be placed just in the power space 12, thereby minimizing the occupation of the internal space of the entire bag 1, so that the storage space 11 has a large enough volume to place other items needed for travel. While serving as a storage point power supply equipment, it also has the loading capacity of a bag, making it convenient to carry and use when traveling.

[0032] When carrying the bag outside, the solar panel module 2 is folded into a shape that matches the shape and size of the bag body 1 and fixed to the outer side of the bag body 1. The folded solar panel module 2 and the bag body 1 are integrated, making the overall volume of the bag 1 small and convenient to carry. When photovoltaic power is needed from the solar panel 21, the solar panel module 2 can be simply unfolded to increase the area of ​​the solar panel module 2 that receives sunlight, thereby providing sufficient photovoltaic power to the energy storage power supply module 3 for energy storage or power supply to external devices.

[0033] The bag body 1 is designed with waterproof fabric, and the solar panel module 2 is also wrapped with waterproof fabric at the edge. At this time, this storage bag has a certain waterproof and rainproof effect. In addition to protecting the digital appliances placed in the bag by the user, it also protects the built-in energy storage power module 3 and the solar panel module 2, and has higher safety than traditional energy storage power supplies.

[0034] like Figure 2As shown, the bag body 1 is provided with a power supply partition 5, which is connected to the interior of the bag body 1 and forms a power supply space 12 with one inner side wall of the bag body 1. The power supply partition 5 and the other inner side wall of the bag body 1 form a storage space 11. The power supply partition 5 can be fixedly connected to the interior of the bag body 1, for example, by sewing or other non-removable means, so that the energy storage power supply module 3 is hidden between the power supply partition 5 and an inner side wall of the bag body 1. The slim energy storage power supply module 3 is respectively attached to the power supply partition 5 and the side wall of the bag body 1, thereby reducing excessive occupation of the storage space 11.

[0035] The power partition 5 and the bag body 1 can also be connected by a zipper or other means. The user can unzip the zipper to open the power space 12, thereby removing or placing the energy storage power module 3, which can facilitate the replacement or maintenance of the energy storage power module 3, thereby meeting different usage needs. The power partition 5 separates the power space 12 from the storage space 11, so that when other items are loaded into the bag, they will not block the placement space of the energy storage power module 3, and prevent other items from colliding with the connection wires of the energy storage power module 3, causing problems such as poor contact of the energy storage power module 3.

[0036] like Figure 7 and 8 As shown, the solar panel module 2 comprises a plurality of sequentially joined solar panels 21. The dimensions of each solar panel 21 match the exterior surface of the bag 1. One end of one solar panel 21 is fixedly connected to the exterior surface of the bag 1. The plurality of solar panels 21 are folded over one another and then stored within the exterior surface of the bag 1. The foldable and storable solar panels 21 are embedded within the bag and can be unfolded at any time to recharge the energy storage power module 3 within the bag in sunlight.

[0037] The outer ring of each solar panel 21 can be wrapped with the same fabric as the bag 1. Multiple solar panels 21 can be wrapped in the same piece of fabric in sequence. Taking advantage of the softness of the fabric, two adjacent solar panels 21 can be flipped and folded over each other. Of course, the solar panels 21 can also be connected by hinges or joints that can be flipped to form a folding effect. One end of one solar panel 21 can be fixedly connected to the bag 1 by sewing the wrapping fabric, or it can be fixed by sewing the wrapping fabric to the bag 1. Figure 7 As shown, the solar panels 21 are connected by snap fasteners or other connecting parts. After the multiple solar panels 21 are folded, the surface of the outermost solar panel 21 can be connected to the bag body 1 through a Velcro strip to fix the folded solar panels 21; Figure 8As shown, a hoop 14 is provided inside the bag 1. After the solar panel 21 is folded, it is fixed by tightening the hoop 14. The middle of the hoop 14 can also be connected by a buckle. The buckles at both ends are docked to tighten the folded solar panel 21, thereby achieving a storage effect.

[0038] The storage bag also includes a solar panel shield 6, which is connected to the bag body 1. The solar panel shield 6 and the outer side of the bag body 1 form a storage space 13, and the folded solar panel 21 is located in the storage space 13. The solar panel shield 6 and the bag body 1 can be connected by a zipper or other means. After the solar panel 21 is stored, the solar panel shield is connected to the bag body 1 to cover the solar panel 21 inside the bag body 1. The solar panel shield 6 can also be made of waterproof material, thereby further protecting the solar panel 21 from water and rain.

[0039] The energy storage power module 3 includes a built-in lithium-ion battery pack, a charging management system, a lithium battery BMS protection circuit, an MCU microcontroller, an output protection circuit, and a temperature detection circuit. The MCU microcontroller is respectively connected to and controls the charging management system, the lithium battery BMS protection circuit, the output protection circuit, and the temperature detection circuit. The solar panel module 2 is connected to the lithium-ion battery pack and supplies power to the lithium-ion battery pack. The lithium-ion battery pack is respectively connected to the charging management system and the lithium battery BMS protection circuit.

[0040] The charge management system, lithium battery BMS protection circuit, MCU microcontroller, output protection circuit, and temperature detection circuit can be integrated into the energy storage power module 3 using existing, well-established circuits. A lithium-ion battery pack consists of multiple lithium-ion cells connected in series and parallel, using high-energy-density lithium-ion cells as the primary energy storage component. The MCU microcontroller and lithium battery BMS protection circuit provide both software and hardware protection for the lithium-ion battery pack.

[0041] The lithium-ion battery pack charging management system supports charging via the built-in solar panel 21 of the storage bag. A cable connects the built-in solar panel 21 to the storage bag for solar charging. The built-in energy storage power module 3 also supports multiple charging methods, and can be charged using an external charging adapter or a car charger without removing the storage bag.

[0042] Interface panel 4 includes a USB output port, a DC output port, and an external DC charging input port. These ports are connected to the lithium-ion battery pack of energy storage power module 3 and are powered by the lithium-ion battery pack. Electronic devices, lighting equipment, and other devices can be charged through these ports, completing the DC power supply mode of the energy storage power module 3.

[0043] The storage bag also includes a lighting fixture, mounted on the bag body 1 and connected to the energy storage power module 3 via a cable. A cable connects the power supply and control signals to the internal energy storage power module 3 via an external interface panel 4. The integrated lighting fixture is also connected to the internal energy storage power module via a cable, enabling on / off control of the lighting fixture.

[0044] Example 2:

[0045] Based on the first embodiment, Figure 3 As shown, the energy storage power supply module also includes a built-in DC-to-AC inverter module. An MCU microcontroller is connected to and controls the DC-to-AC inverter module, and an output protection circuit and lithium-ion battery pack are connected to the DC-to-AC inverter module. The DC-to-AC inverter module is integrated within the energy storage power supply module 3. The MCU microcontroller is connected to and controls the DC-to-AC inverter module, and an output protection circuit is connected to the DC-to-AC inverter module. The output protection circuit protects the DC-to-AC inverter module from output short circuits and overpower. The DC power output from the lithium-ion battery pack is converted to AC power for output via the DC-to-AC inverter module. The DC-to-AC inverter module can utilize a well-established existing DC-to-AC inverter circuit for integration into the energy storage power supply module 3.

[0046] The DC to AC inverter module is connected to the lithium-ion battery pack to convert the DC power output by the lithium-ion battery pack into AC power and output it to the electrical appliance. The output protection circuit is controlled by the inverter control protection circuit in the MCU microcontroller to achieve output end protection, including short circuit protection, overpower protection, and temperature protection.

[0047] This storage bag also includes an active radiator. When the DC to AC inverter module is integrated into the energy storage power module 3, the active radiator is integrated into the energy storage power module 3. The energy storage power module 3 also has a built-in active heat dissipation control circuit. The active heat dissipation control circuit is connected to the active radiator. The MCU microcontroller controls the active heat dissipation control circuit through the signal feedback from the temperature detection circuit.

[0048] The storage bag can utilize passive cooling. When the embedded energy storage power module 3 is a low-power device with low heat generation, passive cooling can be achieved through the bag body 1. However, when the embedded energy storage power module 3 incorporates a DC-to-AC inverter module, an active heat sink (i.e., an active cooling fan) is integrated. The active cooling control circuit and temperature detection circuit are connected to the MCU. When the temperature in the core area of ​​the energy storage power module 3 exceeds a set safety threshold, the temperature detection circuit provides a feedback signal to the MCU, which activates the active heat sink to dissipate heat and reduce the temperature.

[0049] like Figure 4As shown, the interface panel 4 also includes an AC power output interface. The AC power output interface is connected to the DC-to-AC inverter module. The DC-to-AC inverter module converts the power output from the lithium-ion battery pack into AC power, which is then used to power the AC power output interface. The interface panel 4 may also include a battery remaining charge indicator and a power button to display the battery status in real time, making it easier for the user to make decisions. The power button allows the user to start charging the energy storage power module 3 at any time, or to shut it down when not in use to avoid wasting power.

[0050] While the energy storage power supply module 3 in Example 1 only supports DC power supply mode, this second embodiment adds a built-in DC-to-AC inverter module to the energy storage power supply module 3 in Example 1. This allows the energy storage power supply module 3 to not only support DC power supply mode but also add AC power supply functionality, enabling it to charge a wider range of devices requiring AC charging. The DC-to-AC inverter module can be integrated into the energy storage power supply module 3 as an optional feature.

[0051] Example 3:

[0052] like Figures 5 to 6 As shown, based on the first embodiment, this storage bag also includes a DC to AC inverter 8, and an inverter chamber 7 is also provided inside the bag body 1. The DC to AC inverter 8 is placed in the inverter chamber 7. When in use, the DC to AC inverter 8 is connected to the energy storage power supply module 3 through the interface panel.

[0053] The storage bag in Example 1 is a low-end version and does not have an AC output function or interface. The built-in battery module energy storage power supply module 3 does not have an inverter function. When a user uses the storage bag in Example 1 and wants to realize the AC output charging function, they can choose to purchase a separate DC-to-AC inverter 8. At the same time, the bag body 1 can be replaced with a storage bag structure with an inverter chamber 7. The inverter chamber 7 can be a net pocket located on the side of the bag body 1 for placing accessories such as the DC-to-AC inverter 8. In this third embodiment, when the user needs to charge with AC power, they can remove the DC-to-AC inverter 8 separately, connect one end of the DC-to-AC inverter 8 to the DC output interface on the interface panel 4 of the bag body 1, and then connect the external device 9 to be charged to the DC-to-AC inverter 8. The DC-to-AC inverter 8 can then be used to expand the AC output function.

[0054] This third embodiment is also based on the first embodiment, where the energy storage power supply module 3 only supports the addition of a DC-to-AC inverter 8 in the DC power supply mode. However, unlike the addition method in the second embodiment, this third embodiment uses an external DC-to-AC inverter 8; the energy storage power supply module 3 itself does not have a built-in DC-to-AC inverter module. After placing the independent DC-to-AC inverter 8 within the inverter chamber 7 and connecting it to the energy storage power supply module 3 via a cable, it can also charge more external devices 9 that require AC charging.

[0055] When users select products, they have more options:

[0056] First, in the first embodiment, the storage bag is not equipped with an independent DC to AC inverter 8, and the energy storage power supply module 3 does not have a built-in DC to AC inverter module. This low-profile storage bag can only realize a simple DC power supply mode.

[0057] Second, in the second embodiment, the energy storage power supply module 3 including the built-in DC to AC inverter module is accommodated, so that both the DC power supply mode and the AC power supply mode can be realized;

[0058] Third, in the third embodiment, an independent DC to AC inverter 8 is selected and matched with the energy storage power module 3 of the storage bag, so that both the DC power supply mode and the AC power supply mode can be realized.

[0059] The bag body 1 of the portable storage bag with integrated solar energy storage can also be provided with a handle 15 or a shoulder strap for users to carry and carry conveniently. The shoulder strap can be directly integrated into the bag body 1, or a buckle 16 for connecting the shoulder strap can be provided only on the bag body 1. By connecting the external shoulder strap with the buckle 16, the user can carry the storage bag conveniently, making it convenient for users to carry it outdoors.

[0060] This storage bag incorporates a slim energy storage power module 3 and a foldable solar panel 21, minimizing the impact on the space available to consumers. The bag's exterior features charging input and output, control, and internal connection to the built-in energy storage power module 3 via a cable. This allows the bag to possess many of the properties of an energy storage power source, including rechargeability and multiple output interfaces, including USB, DC12V / 24V, and AC output, without removing the built-in energy storage power module 3. The bag can also incorporate an emergency lighting system for emergency lighting in the event of a power outage. The bag integrates a foldable solar panel 21, which users can unfold and use sunlight to recharge the bag's built-in energy storage power module 3. Alternatively, the bag can be charged through the bag's charging window using an external charging adapter without removing the built-in energy storage power module 3.

[0061] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
