[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Please refer to Figures 1 to 3As shown, in an embodiment of the present invention, a portable energy storage device is provided, which includes a power supply unit 1 and a folding umbrella 2. The power supply unit 1 is provided with a battery 13 for storing electrical energy, and the surface of the folding umbrella 2 is provided with a flexible photovoltaic film 3 for converting light energy into electrical energy. A mounting structure 6 is provided between the power supply unit 1 and the folding umbrella 2. The folding umbrella 2 is disassembled and mounted on the power supply unit 1 through the mounting structure 6. A first connecting portion 4 for electrically connecting to the flexible photovoltaic film 3 is provided on the handle 24 of the folding umbrella 2. A second connecting portion 5 for electrically connecting to the battery 13 is provided on the power supply unit 1. The second connecting portion 5 is used to electrically connect to the first connecting portion 4 when the folding umbrella 2 is installed on the power supply unit 1, and a storage structure 7 is also provided on the power supply unit 1. The storage structure 7 is used to accommodate the folding umbrella 2 after being separated from the power supply unit 1.

[0027] Specifically, the power supply unit 1 refers to a component that can store and output electrical energy. A battery 13 is provided within the power supply unit 1, and a charge-discharge unit may also be provided within the power supply unit 1 to control the charging and discharging of the battery 13. The folding umbrella 2 refers to a foldable umbrella structure that can be opened when in use and folded up when not in use. The flexible photovoltaic film 3 refers to a flexible solar panel. The flexible photovoltaic film 3 can be attached to the outside of the umbrella 2 by adhesive bonding or other means, or it can directly serve as the umbrella 2. By attaching the flexible photovoltaic film 3 to the surface of the folding umbrella 2, the flexible photovoltaic film 3 can unfold as the folding umbrella 2 opens and fold as the folding umbrella 2 closes. The first connecting portion 4 and the second connecting portion 5 both refer to components of a certain volume. The first connecting portion 4 can electrically connect to the second connecting portion 5. The first connecting portion 4 can be a plug, in which case the second connecting portion 5 can be a socket. Alternatively, the first connecting portion 4 can be a socket, in which case the second connecting portion 5 can be a plug. Of course, the first connecting portion 4 and the second connecting portion 5 can also be other structures that can achieve electrical connection, which will not be described in detail here. The mounting structure 6 refers to the structure that connects the two components to each other in a removable manner. The mounting structure 6 can connect the umbrella handle 24 to the power supply unit 1 through a snap connection, fastener connection, threaded connection, etc. The storage structure 7 refers to a structure with a certain storage space. The storage structure 7 can be a groove structure recessed in the power supply unit 1, or a container structure additionally provided on the outer wall of the power supply unit 1. The container structure can be fixed by fasteners, welding, or snap connection.

[0028] The portable energy storage device provided by the embodiment of the present invention has a battery 13 disposed within a power supply unit 1, and a second connection portion 5 electrically connected to the battery 13 is disposed on the power supply unit 1. A flexible photovoltaic film 3 capable of converting light energy into electrical energy is disposed on the surface of the folding umbrella 2, and a first connection portion 4 for electrically connecting to the flexible photovoltaic film 3 is disposed on the handle 24 of the folding umbrella 2. Furthermore, a mounting structure is disposed between the handle 24 of the folding umbrella 2 and the power supply unit 1, and a storage structure 7 is also disposed on the power supply unit 1. Compared to conventional solar outdoor energy storage devices, the folding umbrella 2 can be opened during operation, and the handle 24 of the folding umbrella 2 can be detached and connected to the power supply unit 1 via the mounting structure 6. After the handle 24 is connected to the power supply unit 1, the first connection portion 4 on the handle 24 can be electrically connected to the second connection portion 5 on the power supply unit 1, thereby achieving electrical connection between the flexible photovoltaic film 3 and the battery 13. When not in use, the folding umbrella 2 can be separated from the power supply unit 1 and then folded, and the folded folding umbrella 2 can be placed in the storage structure 7 on the power supply unit 1, so that the entire energy storage device can be carried more conveniently.

[0029] It should be noted that a charge and discharge control module may also be provided within the power supply unit 1, which can be used to control the charging and discharging of the battery 13. In addition to the second connection portion 5, the power supply unit 1 may also be provided with other charging and discharging interfaces, such as an AC (Alternating Current) output interface to provide 220V AC output, or a USB (Universal Serial Bus) output interface to charge and discharge mobile devices.

[0030] In one embodiment, see Figure 2 and Figure 3 The first connecting part 4 includes a connecting plug, and the second connecting part 5 includes a connecting socket. The connecting plug has a first conductive component 41, and the connecting socket has a second conductive component 51. The connecting plug and the connecting socket are plugged into each other. The first conductive component 41 and the second conductive component 51 are used to contact when the connecting plug and the connecting socket are plugged into each other to electrically connect the connecting plug and the connecting socket, thereby electrically connecting the flexible photovoltaic film 3 to the battery.

[0031] Specifically, a connecting plug and a connecting socket both refer to components that electrically connect an object or device to another object or device. The connecting plug and the connecting socket are physically connected to each other to achieve current transmission. The connecting plug and the connecting socket are typically mated by plugging. For example, the connecting plug is provided with a protrusion, and the connecting socket is provided with a receiving portion for mating with the protrusion. The plug-in mating of the connecting plug and the connecting socket is achieved by inserting the protrusion on the connecting plug into the receiving portion on the connecting socket. The first conductive component 41 refers to a component capable of conducting current. The first conductive component 41 can be a single component or a combination of multiple components, and the number of first conductive components can be multiple. The first conductive component 41 can be disposed on the protrusion of the connecting plug, for example, the protrusion is provided with a receiving hole, and the first conductive component 41 is disposed within the aforementioned receiving hole, or the first conductive component 41 can directly form the protrusion of the connecting socket. The second conductive component 51 refers to a component capable of conducting current. The second conductive component can be a single component or a combination of multiple components, and the number of second conductive components can be multiple. The second conductive component 51 is arranged in the accommodating portion on the connecting socket. If the accommodating portion is an accommodating groove 71, one end of the second conductive component is arranged on the bottom surface of the accommodating groove 71, and the other end of the second conductive component extends toward the mouth of the accommodating groove 71, and can be inserted into the accommodating hole to electrically contact the first conductive component 41.

[0032] When the umbrella handle 24 of the folding umbrella 2 needs to be electrically connected to the battery part, the connecting plug and the connecting socket can be plugged into each other, and when the connecting plug and the connecting socket are plugged into each other, the first conductive component 41 and the second conductive component 51 contact each other to achieve electrical conduction between the connecting plug and the connecting socket, thereby making the electrical connection between the folding umbrella 2 and the battery part more convenient and quicker, and also making the installation of the folding umbrella 2 faster.

[0033] In one embodiment, see Figure 3The mounting structure 6 includes a movable sleeve 61 and a fixing member 62. The movable sleeve 61 is movably mounted on the outside of the umbrella handle 24. The handle 24 is provided with a limiter 25, which is used to prevent the movable sleeve 61 from being separated from the umbrella handle 24. The fixing member 62 is provided on the power supply unit 1. The movable sleeve 61 is used to be detached from the fixing member 62 when the connecting plug is plugged into the connecting socket, and the limiter 25 is used to press and fix the umbrella handle 24 to the power supply unit 1. Specifically, the movable sleeve 61 is a cylindrical component of a certain length. The movable sleeve 61 is movably mounted on the outside of the umbrella handle 24, which means that the movable sleeve 61 can rotate relative to the umbrella handle 24 and move relative to the umbrella handle 24 along the axis of the umbrella handle 24. The limiter 25 is a component of a certain volume. The limiter 25 can be block-shaped, columnar, or annular and arranged around the circumference of the umbrella handle 24. The stopper 25 protrudes from the outer surface of the handle 24 and abuts against at least a portion of the movable sleeve 61 when the movable sleeve 61 moves along the axis of the handle 24, preventing the movable sleeve 61 from detaching from the end of the handle 24. The fixing member 62 is a component having a certain height dimension. The fixing member 62 can be shaped like a column, a block, or a tube. To secure the handle 24 to the power supply unit 1, the connecting plug and the connecting socket are first connected. The movable sleeve 61 is then moved along the axis of the handle 24 toward the fixing member 62 until it is finally disconnected from the fixing member 62. Furthermore, when the movable sleeve 61 is disconnected from the fixing member 62, the stopper 25 also abuts against the movable sleeve 61, allowing the movable sleeve 61 to press the handle 24 against the power supply unit 1 through the stopper 25. This facilitates the connection of the handle 24 to the battery unit and the securement of the folding umbrella 2.

[0034] In one embodiment, see Figure 3 The fixing member 62 comprises a sleeve disposed around the connecting socket. The sleeve's cross-section matches the cross-sectional shape of the umbrella handle 24, and when the connecting plug and the connecting socket are plugged into each other, the umbrella handle 24 is inserted into the sleeve. Specifically, the sleeve is a cylindrical component of a certain height that is mounted outside the connecting socket. One end of the sleeve can be connected to the battery unit, and the other end can extend away from the battery unit. The sleeve can be integral with the battery unit housing, or it can be a separate component connected to the battery unit housing via welding, clamping, fasteners, or adhesive bonding. The cross-sectional shape of the sleeve refers to a cross-section taken along a plane perpendicular to the sleeve's axis, while the cross-sectional shape of the umbrella handle 24 refers to a cross-sectional shape taken along a plane perpendicular to the axis of the umbrella handle 24. By matching the cross-sectional shape of the sleeve with the cross-sectional shape of the umbrella handle 24, when the umbrella handle 24 is inserted into the sleeve, the outer wall of the umbrella handle 24 abuts against the inner wall of the sleeve, thereby enabling the sleeve to support the umbrella handle 24 along the sleeve's axis.

[0035] In one embodiment, see Figure 3The inner wall of the movable sleeve 61 is provided with a first thread 63, and the outer wall of the sleeve is provided with a second thread 64 that meshes with the first thread 63. The movable sleeve 61 is detachably connected to the sleeve through the first thread 63 and the second thread 64. Specifically, the first thread 63 and the second thread 64 both refer to spiral protrusions or grooves provided on the surface or inner wall of an object. By providing the first thread 63 on the inner wall of the movable sleeve 61 and providing the second thread 64 that meshes with the first thread 63 on the outer wall of the sleeve, when the movable sleeve 61 is in contact with the sleeve, the detachable connection between the movable sleeve 61 and the sleeve can be achieved by rotating the movable sleeve 61, thereby making the detachable connection between the movable sleeve 61 and the sleeve more convenient.

[0036] In one embodiment, see Figure 2 The folding umbrella 2 includes a telescopic pole 21, folding ribs 22, and an umbrella cover 23. The folding ribs 22 are movably mounted on the first end of the telescopic pole 21. The handle 24 is mounted on the second end of the telescopic pole 21. The umbrella cover 23 is connected to the folding ribs 22. The flexible photovoltaic film 3 is positioned outside the umbrella cover 23 or directly forms part of the umbrella cover 23. Specifically, the telescopic pole 21 is a rod-shaped component that can be extended or shortened. The telescopic pole 21 can be formed by sequentially connecting multiple rods with internal sliding spaces. The folding ribs 22 are the skeletal structure that supports the umbrella cover. The folding ribs 22 are movably mounted on the first end of the telescopic pole 21. The folding ribs 22 and the umbrella cover 23 can be folded and opened by the movement of the folding ribs 22. The flexible photovoltaic film 3 is positioned outside the umbrella cover 23 or directly forms part of the umbrella cover 23, allowing the flexible photovoltaic film 3 to fold and open along with the umbrella cover. By adopting this structure, the folding umbrella 2 is more convenient to fold and has a smaller volume when folded.

[0037] In an alternative embodiment, see Figure 2The flexible photovoltaic film 3 is disposed on the outside of the umbrella face 23. The umbrella face 23 can be made of materials such as polyester fiber and polypropylene. These materials have good foldability and light weight, and also have good weather resistance and UV resistance. They can withstand long-term exposure to sunlight, wind, rain, and other harsh environments. They can also be treated to form a hydrophobic layer to prevent rainwater from penetrating, thereby protecting equipment. The flexible photovoltaic film 3 and the umbrella face 23 can be firmly bonded together using adhesive technology. Since both are flexible materials, they are also very easy to fold. The connecting components between the folding umbrella ribs 22 and the umbrella face 23 can be made of soft waterproof cloth or silicone material. This allows the folding umbrella ribs 22 to fit tightly with the umbrella face 23, ensuring that no gaps are formed between the umbrella face 23 and the folding umbrella ribs 22 during opening and retraction. A locking device can be provided on the telescopic umbrella pole 21. The locking device can be used to fix at least a portion of the folding umbrella ribs 22 to keep the folding umbrella 2 in the folded state. When the locking device is unlocked, the folding umbrella ribs 22 will open and the umbrella face will unfold together. The folding umbrella ribs 22 and the telescopic umbrella pole 21 can be made of a carbon fiber composite material with high strength and durability, and have the characteristics of being light and easy to carry and fold, thereby improving the portability of the folding umbrella 2.

[0038] In one embodiment, see Figure 3 The telescopic umbrella pole 21 has an interior mounting channel 26. A connecting wire 9 for electrically connecting the flexible photovoltaic film 3 to the first connecting portion 4 is also located within the mounting channel 26. A winding assembly 8 is also located within the handle 24. The winding assembly 8 is used to wind the connecting wire 9 around the winding assembly 8 when the telescopic umbrella pole 21 is shortened. Specifically, the mounting channel 26 is a receiving structure provided along the length of the telescopic umbrella pole 21. The connecting wire 9 is a flexible conductive component that electrically connects two components or devices. The connecting wire 9 is disposed within the mounting channel 26. The winding assembly 8 is a component for winding the connecting wire 9. The winding assembly 8 can be a winding reel 81 that is rotatably disposed within the handle 24. The handle 24 also has an installation space 27 that communicates with the mounting channel 26. The winding assembly 8 can be disposed within the installation space 27. The mounting channel 26 and the connecting wire 9 disposed within the mounting channel 26 within the telescopic umbrella pole 21 facilitate electrical connection between the flexible photovoltaic film 3 and the first connecting portion 4. A winding assembly 8 is also disposed within the handle 24. The connecting wire 9 passes through the winding assembly 8 before being connected to the first connecting portion 4. The winding assembly 8 can wind the connecting wire 9 around the winding assembly 8 when the telescopic umbrella pole 21 is shortened, thereby preventing the connecting wire 9 from accumulating in the mounting channel 26. The winding assembly 8 can also release the connecting wire 9 from the winding assembly 8 as the telescopic umbrella pole 21 is extended, thereby causing the length of the connecting wire 9 in the mounting channel 26 to change accordingly with the extension of the telescopic umbrella pole 21. This makes the extension and retraction of the entire telescopic umbrella pole 21 more convenient, thereby improving the convenience of the folding umbrella 3.

[0039] In one embodiment, see Figure 3 The winding assembly 8 includes a winding wheel 81 and an elastic member 82. The winding wheel 81 is rotatably arranged inside the umbrella handle 24 for winding the connecting wire 9. The elastic member 82 is arranged inside the umbrella handle 24 for applying a force to the winding wheel 81 to rotate in a first direction. The first direction is the rotation direction of the winding wheel 81 when winding the connecting wire 9. The winding wheel 81 refers to a disc-shaped component with a certain volume. The winding wheel 81 is rotatably arranged in the installation space 27 inside the umbrella handle 24. The elastic member 82 refers to an elastic component with a certain length. The elastic member 82 can be a spring, a torsion spring or a rubber member. During operation, at least part of the connecting wire 9 can be wound around the circumference of the winding wheel 81. At the same time, an elastic member 82 is also provided in the installation space 27. The elastic member 82 applies a force to the winding wheel 81 to rotate in a first direction. The first direction is the rotation direction of the winding wheel 81 when winding the connecting wire 9. When the telescopic umbrella pole 21 is shortened, the elastic member 82 drives the winding wheel 81 to rotate and wind the connecting wire 9 onto the winding wheel 81, thereby preventing the connecting wire 9 from accumulating in the installation channel 26. When the telescopic umbrella pole 21 is extended, the connecting wire 9 pulls the winding wheel 81 in a direction opposite to the first direction, and the elastic member 82 is stretched, so that the length of the connecting wire 9 in the installation channel 26 changes accordingly with the extension of the telescopic umbrella pole 21. This makes the shortening and extension of the entire telescopic umbrella pole 21 more convenient, and improves the convenience of use of the folding umbrella 2.

[0040] In one embodiment, see Figure 2 The storage structure 7 includes a receiving groove 71 provided on the power supply unit 1, and a sealing cover 72 is provided at the mouth of the receiving groove 71. Specifically, the receiving groove 71 refers to a groove structure with a certain receiving space, and the volume of the receiving groove 71 matches the volume of the folding umbrella 2 after folding. The receiving groove 71 can be provided on the top of the power supply unit 1 or on the side of the power supply unit 1. The sealing cover 72 refers to a component with a certain area, and the sealing cover 72 can be plate-shaped. The folded folding umbrella 2 can be accommodated by the receiving groove 71 on the power supply unit 1, and the mouth of the receiving groove 71 is covered by the sealing cover 72, making the energy storage device more convenient to carry. In addition, one end of the sealing cover 72 is hingedly connected to the power supply unit 1, and an elastic torsion spring can be provided at the hinge between the sealing cover 72 and the power supply unit 1, which can automatically close under the action of the elastic torsion spring after the sealing cover 72 is opened.

[0041] In one embodiment, see Figure 1The power supply unit 1 is provided with a plurality of movable rollers 11 at the bottom and a carrying handle 12 at the top. The plurality of movable rollers 11 at the bottom of the power supply unit 1 allow the power supply unit 1 to be moved by simply pushing it. Furthermore, the carrying handle 12 is provided at the top of the power supply unit 1, allowing the power supply unit 1 to be lifted and carried. This provides multiple means for carrying the power supply unit 1, making it more convenient to carry and transport the power supply unit 1.

[0042] In an optional embodiment, a lighting unit may be further provided on the power supply unit 1 . The lighting unit is electrically connected to the battery 13 and can provide lighting outdoors, thereby improving the convenience of use.

[0043] The above description is merely a preferred embodiment of the present invention and specifically describes the technical principles of the present invention. These descriptions are intended only to explain the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention.
