[0062] The energy storage device 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0063] Combine Figure 1 and Figure 2 As shown, the energy storage device 1000 according to an embodiment of the present invention includes: a housing 100 , an output component 400 , an input component 500 and a main control component 600 .

[0064] Among them, combined Figure 1 and Figure 2 As shown, the output assembly 400 includes an output panel 410 and an output module 420 disposed on the output panel 410. The output panel 410 is disposed on the housing 100, and the output module 420 is used to output the electrical energy of the energy storage device 1000. By configuring the output assembly 400 to include the output panel 410 and the output module 420, during the assembly of the energy storage device 1000, the output module 420 can be directly mounted to the output panel 410 to form a modular output assembly 400, thereby reducing the difficulty of assembling the energy storage device 1000.

[0065] At the same time, by configuring the output module 420 to output the electrical energy of the energy storage device 1000 , the output module 420 can be used to supply the electrical energy of the energy storage device 1000 to a load or a power grid to ensure the working performance of the energy storage device 1000 .

[0066] Combine Figure 1 and Figure 2 As shown, the input assembly 500 includes an input panel 510 and an input module 520 disposed on the input panel 510. The input panel 510 is disposed on the housing 100, and the input module 520 is used to input electrical energy into the energy storage device 1000. By configuring the input assembly 500 to include the input panel 510 and the input module 520, during the assembly of the energy storage device 1000, the input module 520 can be directly mounted to the input panel 510 to form a modular input assembly 500, thereby reducing the difficulty of assembling the energy storage device 1000.

[0067] At the same time, by configuring the input module 520 to input electrical energy toward the energy storage device 1000, the input module 520 can be used to receive electrical energy from the power grid, or to receive electrical energy from other renewable energy (such as solar energy, wind energy) power generation systems, so as to charge the energy storage device 1000 and ensure the working performance of the energy storage device 1000 to a certain extent.

[0068] It should be noted that, in order to facilitate interconnection and intercommunication between different devices, the input module 520 may adopt a standardized interface design.

[0069] Combine Figure 2 、 Figure 3 and Figure 4 As shown, the main control assembly 600 includes a main control panel 610 and a circuit board 620 disposed on the main control panel 610. The main control panel 610 is disposed on the housing 100. The circuit board 620 is used to control the energy storage device 1000. At least one of the input panel 510, the output panel 410, and the main control panel 610 is a separate panel, and the separate panel and the housing 100 are separate components. By configuring the main control assembly 600 to include the main control panel 610 and the circuit board 620, during the assembly process of the energy storage device 1000, the circuit board 620 can be directly mounted to the main control panel 610, thereby forming a modular main control assembly 600, reducing the difficulty of assembling the energy storage device 1000.

[0070] At the same time, by configuring the circuit board 620 to control the energy storage device 1000 , the main control component 600 can be used to monitor and control the operating status of the entire energy storage device 1000 , thereby ensuring the operating performance of the energy storage device 1000 to a certain extent.

[0071] It should be noted that by arranging the output panel 410, the input panel 510 and the main control panel 610 in the housing 100, while improving the integration of the energy storage device 1000, the housing 100 can also be used to support the output component 400, the input component 500 and the main control component 600, so as to improve the positional stability of the output component 400, the input component 500 and the main control component 600, to a certain extent ensure the working performance of the output component 400, the input component 500 and the main control component 600, and reduce the difficulty of fixing the output component 400, the input component 500 and the main control component 600.

[0072] It is worth noting that the present application configures at least one of the input panel 510, the output panel 410 and the main control panel 610 as a split panel, and configures the split panel and the housing 100 as split parts, that is, at least one of the input panel 510, the output panel 410 and the main control panel 610 and the housing 100 are formed as split parts. In this way, during the assembly process of the energy storage device 1000, when the input panel 510 and the housing 100 are split parts, the input module 520 can be first installed to the input panel 510 to form a modular input component 500, and then the input panel 510 can be set on the housing 100, so that the energy storage device 1000 forms a modular assembly.

[0073] Accordingly, when the output panel 410 and the housing 100 are separate parts, during the assembly of the energy storage device 1000, the output module 420 can be first installed on the output panel 410 to form a modular output component 400, and then the output panel 410 can be set on the housing 100, so that the energy storage device 1000 forms a modular assembly.

[0074] At the same time, when the main control panel 610 and the outer shell 100 are separate parts, during the assembly process of the energy storage device 1000, the circuit board 620 can be first installed on the main control panel 610 to form a modular main control component 600, and then the main control component 600 can be set on the outer shell 100, so that the energy storage device 1000 forms a modular assembly, which facilitates the assembly and maintenance of the energy storage device 1000 and reduces the maintenance cost of the energy storage device 1000.

[0075] As can be seen from the above structure, the energy storage device 1000 of the embodiment of the present invention ensures the working performance of the energy storage device 1000 by providing the housing 100 , the output component 400 , the input component 500 and the main control component 600 .

[0076] At the same time, by configuring at least one of the input panel 510, the output panel 410, and the main control panel 610 to be formed as a separate part from the housing 100, a modular design of the energy storage device 1000 can be achieved in terms of structure, so as to form a modular input component 400, a modular output component 500, and a modular main control component 600. In this way, during the assembly process of the energy storage device 1000, the energy storage device 1000 can be assembled in a modular manner, which is conducive to reducing the difficulty of assembling and maintaining the energy storage device 1000, thereby facilitating the assembly and maintenance of the energy storage device 1000.

[0077] It is understandable that compared with the prior art, the present application modularizes the energy storage device 1000 so that the energy storage device 1000 is modularly assembled, reducing the difficulty of assembling and maintaining the energy storage device 1000, thereby facilitating the assembly and maintenance of the energy storage device 1000.

[0078] In some embodiments, at least two of the input panel 510, the output panel 410, and the main control panel 610 are separate panels. That is, at least two of the input panel 510, the output panel 410, and the main control panel 610 are formed as separate components from the housing 100, thereby enabling a modular design of at least two of the input assembly 400, the output assembly 500, and the main control assembly 600. This facilitates modular assembly of the energy storage device 1000 and reduces the difficulty of assembling and maintaining the energy storage device 1000.

[0079] In a specific example, combined with Figure 1 and Figure 2 As shown, the input panel 510, the output panel 410 and the main control panel 610 are all split panels, so that the input panel 510, the output panel 410 and the main control panel 610 are all formed as separate parts with the housing 100, thereby realizing a modular design of the input component 400, the output component 500 and the main control component 600. In this way, during the assembly process of the energy storage device 1000, the input module 520 can be first installed to the input panel 510 to form a modular input component 500, the output module 420 can be installed to the output panel 410 to form a modular output component 400, and the circuit board 620 can be installed to the main control panel 610 to form a modular main control component 600. Then, the input panel 510 is set on the housing 100, the output panel 410 is set on the housing 100, and the main control component 600 is set on the housing 100, so that the energy storage device 1000 forms a modular assembly, which facilitates the assembly and maintenance of the energy storage device 1000 and reduces the maintenance cost of the energy storage device 1000.

[0080] In some embodiments, combined Figure 1 and Figure 2 As shown, the output component 400 , the input component 500 and the main control component 600 are respectively arranged on different sides of the housing 100 . That is to say, the output component 400, the input component 500 and the main control component 600 are respectively arranged on different side walls of the shell 100. On the one hand, it is convenient to simultaneously arrange the output component 400, the input component 500 and the main control component 600 on the shell 100, that is, the output component 400, the input component 500 and the main control component 600 are simultaneously integrated on the shell 100, while reducing the occupied area of ​​the energy storage device 1000. At the same time, the energy storage device 1000 can also be provided with the output component 400, the input component 500 and the main control component 600, so as to ensure the working performance of the energy storage device 1000 to a certain extent; on the other hand, it can also avoid the output component 400, the input component 500 and the main control component 600 from interfering with each other when they are connected with the shell 100, thereby reducing the difficulty of installing the output component 400, the input component 500 and the main control component 600, and thereby reducing the difficulty of assembling the energy storage device 1000.

[0081] In some embodiments, combined Figure 1 and Figure 2 As shown, the main control component 600 is arranged on the front side wall of the shell 100, and the output component 400 and the input component 500 are respectively arranged on the left and right side walls of the shell 100, so as to realize that the output component 400, the input component 500 and the main control component 600 are respectively arranged on different sides of the shell 100.

[0082] At the same time, by arranging the main control component 600 on the front side wall of the housing 100 , it is convenient for the user to operate the main control component 600 , thereby reducing the difficulty of using the energy storage device 1000 .

[0083] In some embodiments, the split panel and the housing 100 are detachably mated. This means that when the input panel 510 and the housing 100 are formed as separate parts, the input panel 510 and the housing 100 are detachably mated. When the output panel 410 and the housing 100 are formed as separate parts, the output panel 410 and the housing 100 are detachably mated. When the main control panel 610 and the housing 100 are formed as separate parts, the main control panel 610 and the housing 100 are detachably mated. This reduces the difficulty of assembling and disassembling the split panel and the housing 100, further reducing the difficulty of assembling the energy storage device 1000.

[0084] At the same time, by arranging the split panel to be detachably matched with the housing 100, it is also convenient to replace the split panel.

[0085] In a specific example, the input panel 510, the output panel 410 and the main control panel 610 are all detachably matched with the housing 100 to reduce the difficulty of assembling the output component 400, the input component 500 and the main control component 600, thereby reducing the difficulty of replacing the output component 400, the input component 500 and the main control component 600.

[0086] It is worth emphasizing that since the specifications of the output modules 420 adapted for different countries are different, by setting the output panel 410 and the housing 100 to be detachable, it is convenient to replace output modules 420 of different specifications, thereby realizing the diversity of the output interface of the energy storage device 1000 to meet the switching of interface specifications in different countries, thereby enabling the energy storage device 1000 to effectively meet market demand and expand the scope of application of the energy storage device 1000.

[0087] In some embodiments, combined Figure 1 and Figure 2As shown, the energy storage device 1000 includes a battery pack 220 , a housing 100 is formed with a receiving cavity 110 , the battery pack 220 is detachably disposed in the receiving cavity 110 , and the output module 420 , the input module 520 and the circuit board 620 are electrically connected to the battery pack 220 . Among them, the battery pack 220 in the energy storage device 1000 is mainly used to store electrical energy. When the output module 420 is electrically connected to the battery pack 220, the output module 420 can be used to output the electrical energy of the battery pack 220, thereby achieving the purpose of outputting electrical energy from the energy storage device 1000. When the input module 520 is electrically connected to the battery pack 220, the input module 520 can be used to input electrical energy toward the battery pack 220, thereby achieving the purpose of inputting electrical energy toward the energy storage device 1000. When the circuit board 620 is electrically connected to the battery pack 220, the circuit board 620 can be used to monitor and control the operating status of the battery pack 220, thereby achieving the purpose of using the main control component 600 to monitor and control the operating status of the entire energy storage device 1000, thereby ensuring the working performance of the energy storage device 1000 to a certain extent.

[0088] In addition, by detachably arranging the battery pack 220 in the accommodating cavity 110, while preventing the battery pack 220 from occupying the external space of the outer shell 100, the outer shell 100 can also be used to protect and support the battery pack 220, thereby extending the service life of the battery pack 220 and improving the position stability of the battery pack 220, thereby ensuring the working performance of the battery pack 220 to a certain extent.

[0089] It is worth noting that the battery pack 220 and the accommodating cavity 110 are detachably matched, so that when the battery pack 220 and the outer shell 100 are processed, they can be processed separately to form a separate battery pack 220 and outer shell 100, thereby facilitating the formation of a modular battery pack 220. In addition, during the assembly process of the battery pack 220 and the outer shell 100, the difficulty of installing and disassembling the battery pack 220 can be reduced, thereby reducing the difficulty of assembling the energy storage device 1000.

[0090] In some embodiments, combined Figure 1 and Figure 2 As shown, the energy storage device 1000 includes an inverter 210, which is detachably connected to and electrically connected to the battery pack 220. The output module 420, the input module 520, and the circuit board 620 are electrically connected to the inverter 210. The output module 420, the input module 520, and the circuit board 620 are electrically connected to the battery pack 220 through the inverter 210. This facilitates the use of the inverter 210 to convert the direct current (DC) in the battery pack 220 into alternating current (AC) to meet the needs of the power grid or load.

[0091] In addition, the inverter 210 can communicate and coordinate with other components of the energy storage device 1000 to achieve centralized control and management of the energy storage device 1000. The inverter 210 can also play a role in isolation and protection between the energy storage device 1000 and the power grid, and can control the size and stability of the output power according to load demand or grid requirements.

[0092] In some embodiments, when the output module 420 is electrically connected to the inverter 210, the inverter 210 can be used to convert the direct current of the battery pack 220 into alternating current, and then supply it to the load or the power grid through the output module 420; when the input module 520 is electrically connected to the inverter 210, the input module 520 is electrically connected to the battery pack 220. The input module 520 is used to receive electrical energy from the power grid, or receive electrical energy from other renewable energy sources (such as solar energy, wind energy) power generation systems to charge the battery pack 220; when the circuit board 620 is electrically connected to the inverter 210, the circuit board 620 is electrically connected to the battery pack 220, so that the main control component 600 can be used to monitor and control the operating status of the entire energy storage device 1000, thereby ensuring the working performance of the energy storage device 1000 to a certain extent.

[0093] It should be noted that, since the battery pack 220 is disposed in the accommodating cavity 110, when the inverter 210 is detachably connected to the battery pack 220, the inverter 210 can also be disposed in the accommodating cavity 110, thereby achieving the goal of accommodating both the inverter 210 and the battery pack 220 in the accommodating cavity 110. While preventing the inverter 210 and the battery pack 220 from occupying the external space of the outer shell 100, the outer shell 100 can also be used to protect and support the inverter 210 and the battery pack 220, thereby extending the service life of the inverter 210 and the battery pack 220, and improving the positional stability of the inverter 210 and the battery pack 220, thereby ensuring the working performance of the inverter 210 and the battery pack 220 to a certain extent.

[0094] At the same time, by making the inverter 210 detachably connected to the battery pack 220, the battery pack 220 and the inverter 210 can be processed separately to form a separate battery pack 220 and inverter 210, thereby facilitating the formation of a modular inverter 210. In addition, during the assembly process of the battery pack 220 and the inverter 210, the difficulty of installing and disassembling the inverter 210 can be reduced, thereby reducing the difficulty of assembling the energy storage device 1000.

[0095] In summary, the present application achieves a structural modular design of the energy storage device 1000 by configuring at least one of the input panel 510, the output panel 410, and the main control panel 610 to be formed as a separate part from the housing 100, and detachably arranging the battery pack 220 in the accommodating cavity 110 and detachably connecting the inverter 210 to the battery pack 220, so as to form a modular inverter 210, a modular battery pack 220, a modular input component 400, a modular output component 500, and a modular main control component 600. In this way, during the assembly process of the energy storage device 1000, the energy storage device 1000 can be modularly assembled, which is conducive to reducing the difficulty of assembling and maintaining the energy storage device 1000, thereby facilitating the assembly and maintenance of the energy storage device 1000.

[0096] In some embodiments, the battery pack 220 includes a case and battery cells, the battery cells are arranged in the case, and the inverter 210 is detachably connected to the case to achieve a detachable connection between the battery pack 220 and the inverter 210, so as to facilitate the formation of a modular inverter 210 and a modular battery pack 220, thereby enabling the energy storage device 1000 to form a modular assembly.

[0097] In some embodiments, an electrical isolation element is provided between the output module 420 and the inverter 210 to prevent safety issues such as current backflow or short circuit to a certain extent, thereby improving the safety of the energy storage device 1000.

[0098] It should be noted that the electrical connection between the battery pack 220 , the output module 420 , the input module 520 , the circuit board 620 and the inverter 210 can be achieved through control signal lines and data lines.

[0099] In some embodiments, combined Figure 1 and Figure 2 As shown, the housing 100 includes a first housing 120 and a second housing 130, which are detachably mated. This reduces the difficulty of assembling the housing 100 and improves assembly efficiency. It also facilitates assembly of the inverter 210 and the battery pack 220 into the accommodating cavity 110 of the housing 100, reducing the difficulty of assembling and maintaining the energy storage device 1000.

[0100] In some embodiments, combined Figure 6 and Figure 7 As shown, one of the first shell 120 and the second shell 130 is provided with a first clip 123, and the other is provided with a first slot 131. The first clip 123 is snap-fitted into the first slot 131 to achieve the snap-fitting of the first shell 120 and the second shell 130, thereby facilitating the detachable fitting of the first shell 120 and the second shell 130 and reducing the difficulty of fitting and connecting the first shell 120 and the second shell 130.

[0101] In a specific example, combined with Figure 6 and Figure 7 As shown, a first buckle 123 is provided on the first shell 120 , and a first slot 131 is provided on the second shell 130 . The first buckle 123 is snap-fitted into the first slot 131 to achieve snap-fitting of the first shell 120 and the second shell 130 .

[0102] Of course, in some other embodiments, a first clip 123 may be provided on the second shell 130 and a first slot 131 may be provided on the first shell 120 (not shown in this example figure). In this way, the first clip 123 may be snapped into place in the first slot 131, thereby achieving snap-fitting of the first shell 120 and the second shell 130.

[0103] In some embodiments, combined Figure 2 and Figure 6 As shown, a nut 124 is provided on the first shell 120, and the housing 100 also includes a first screw 150, which is passed through the second shell 130 and is connected with the nut 124 to achieve a fixed connection between the first shell 120 and the second shell 130, and to make the first shell 120 and the second shell 130 form a detachable fit.

[0104] In some embodiments, combined Figure 2 and Figure 6 As shown, the first screw 150 includes a plurality of screws. The cooperation of the plurality of first screws 150 can increase the connection strength between the first shell 120 and the second shell 130 , thereby improving the structural stability of the housing 100 .

[0105] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0106] Through the above arrangement, during the assembly of the first shell 120 and the second shell 130, the first buckle 123 and the first slot 131 can be used to first achieve positioning and matching of the first shell 120 and the second shell 130. After the positioning is completed, the first screw 150 is passed through the second shell 130 and connected with the nut 124 to achieve a fixed connection between the first shell 120 and the second shell 130, thereby reducing the difficulty of fixing the first shell 120 and the second shell 130, achieving the purpose of simple assembly, improving the production efficiency of the energy storage device 1000, and facilitating subsequent maintenance of the energy storage device 1000.

[0107] In some embodiments, combined Figure 1 、 Figure 2 and Figure 6As shown, the battery pack 220 is installed in the first shell 120, and the inverter 210 is installed on the battery pack 220 and at the same time installed in the first shell 120. In this way, while both the inverter 210 and the battery pack 220 are arranged in the shell 100, the inverter 210 can also be arranged close to the battery pack 220 to facilitate the electrical connection between the inverter 210 and the battery pack 220.

[0108] Optionally, combined Figure 2 、 Figure 8 and Figure 9 As shown, a mounting opening 121 is provided on the side wall of the first housing 120, and the split panel is disposed at the mounting opening 121. This facilitates the installation of the split panel on the first housing 120, and thus on the housing 100, thereby reducing the difficulty of assembling the split panel and the housing 100, and thereby reducing the difficulty of assembling the energy storage device 1000. Furthermore, it facilitates the exposure of structures on the split panel, for example, the input module 520, the output module 420, and the interface 621 on the circuit board 620, thereby reducing the difficulty of using the output component 400, the input component 500, and the main control component 600, and thereby reducing the difficulty of using the energy storage device 1000.

[0109] In some embodiments, combined Figure 2 、 Figure 8 and Figure 9 As shown, three mounting openings 121 are provided on the side wall of the first shell 120, and the three mounting openings 121 are respectively located on different side walls of the first shell 120. The input panel 510, the output panel 410, and the main control panel 610 are respectively provided at one mounting opening 121, so that the input panel 510, the output panel 410, and the main control panel 610 are all provided on the shell 100 and located on different sides of the shell 100. At the same time, the input panel 510, the output panel 410, and the main control panel 610 are all formed as separate parts from the shell 100, which facilitates the modular design of the energy storage device 1000 and reduces the difficulty of assembly and maintenance of the energy storage device 1000.

[0110] In some embodiments, combined Figure 2 、 Figure 8 and Figure 9 As shown, at least one of the top walls of the mounting opening 121 is open, so when assembling the split panel, the split panel can be placed at the mounting opening 121 through the opening, reducing the difficulty of assembling the split panel.

[0111] In a specific example, combined with Figure 2 、 Figure 8 、 Figure 9 and Figure 10As shown, the top wall of the mounting opening 121 for installing the input panel 510 and the output panel 410 is opened to facilitate the installation of the input panel 510 and the output panel 410 at the mounting opening 121, thereby reducing the difficulty of installing and removing the input panel 510 and the output panel 410, thereby facilitating the replacement of output modules 420 of different specifications to meet the switching of interface specifications of different countries and expand the scope of application of the energy storage device 1000.

[0112] In some embodiments, combined Figures 8-16 As shown, the split panel and the first housing 120 are guided and matched by the guide assembly 700. This means that when the input panel 510 and the first housing 120 are separate components, the input panel 510 and the first housing 120 are guided and matched by the guide assembly 700; when the output panel 410 and the first housing 120 are separate components, the output panel 410 and the first housing 120 are guided and matched by the guide assembly 700; when the main control panel 610 and the first housing 120 are separate components, the main control panel 610 and the first housing 120 are guided and matched by the guide assembly 700, thereby reducing the difficulty of matching the split panel with the first housing 120, thereby facilitating the installation of the split panel at the installation opening 121.

[0113] in, Figure 10 and Figure 11 Schematic diagram showing the output panel 410 and the first housing 120 being guided and matched by the guide assembly 700; Figure 15 and Figure 16 It shows a schematic diagram of the main control panel 610 and the first shell 120 being guided and matched by the guide assembly 700.

[0114] It should be noted that the schematic diagram of the guiding cooperation between the input panel 510 and the first shell 120 through the guide assembly 700 can refer to the guiding cooperation relationship between the output panel 410 and the first shell 120 through the guide assembly 700, which is not specifically shown in the figure.

[0115] In some embodiments, combined Figures 8-16 As shown, the guide assembly 700 includes a guide protrusion 710 and a guide groove 720. The guide protrusion 710 is movably engaged with the guide groove 720. One of the guide protrusion 710 and the guide groove 720 is located at the installation opening 121, and the other is located on the split panel. Thus, when the guide protrusion 710 is movably engaged with the guide groove 720, the split panel and the first housing 120 can be guided and engaged, reducing the difficulty of mating the split panel and the first housing 120.

[0116] In some embodiments, combined Figures 8-12As shown, when the output panel 410 is a split panel, the guide protrusion 710 is provided at the mounting opening 121, and the guide groove 720 is provided on the output panel 410. In this way, when the guide protrusion 710 is movably fitted in the guide groove 720, the guiding fit of the output panel 410 and the first shell 120 can be achieved, thereby reducing the difficulty of fitting the output panel 410 and the first shell 120.

[0117] Of course, in some other embodiments, the guide protrusion 710 may also be provided on the output panel 410 , and the guide groove 720 may be provided at the installation opening 121 .

[0118] In some embodiments, when the input panel 510 is a split panel, the guide protrusion 710 is provided at the mounting port 121, and the guide groove 720 is provided on the input panel 510. In this way, when the guide protrusion 710 is movably fitted in the guide groove 720, the guiding fit between the input panel 510 and the first shell 120 can be achieved, thereby reducing the difficulty of fitting between the input panel 510 and the first shell 120.

[0119] Of course, in some other embodiments, the guide protrusion 710 may also be provided on the input panel 510 , and the guide groove 720 may be provided at the installation opening 121 .

[0120] In some embodiments, combined Figure 15 and Figure 16 As shown, when the main control panel 610 is a split panel, the guide protrusion 710 is provided at the installation port 121, and the guide groove 720 is provided on the main control panel 610. In this way, when the guide protrusion 710 is movably engaged in the guide groove 720, the guide limit engagement of the main control panel 610 and the first shell 120 can be achieved, thereby reducing the difficulty of engagement between the main control panel 610 and the first shell 120.

[0121] Of course, in some other embodiments, the guide protrusion 710 may also be provided on the main control panel 610 , and the guide groove 720 may be provided at the installation opening 121 .

[0122] In some embodiments, the split panel and the first shell 120 are guided and matched through multiple guide components 700 to improve the guiding effect of the guide components 700, facilitate the use of the guide components 700 to achieve the matching connection between the split panel and the first shell 120, reduce the connection difficulty, and improve the accuracy of the connection.

[0123] In some embodiments, combined Figure 8-Figure 22As shown, the split panel and the first housing 120 are limited in position by the limiting assembly 800. This means that when the input panel 510 and the first housing 120 are separate components, the input panel 510 and the first housing 120 are limited in position by the limiting assembly 800; when the output panel 410 and the first housing 120 are separate components, the output panel 410 and the first housing 120 are limited in position by the limiting assembly 800; when the main control panel 610 and the first housing 120 are separate components, the main control panel 610 and the first housing 120 are limited in position by the limiting assembly 800, thereby further reducing the difficulty of fitting the split panel with the first housing 120 and achieving position limiting of the split panel, so that the split panel can be stably installed at the installation opening 121.

[0124] in, Figure 13 and Figure 14 Schematic diagram showing the output panel 410 and the first housing 120 being limited and matched by the limiting assembly 800; Figure 21 and Figure 22 It shows a schematic diagram of the main control panel 610 and the first shell 120 being limited and matched by the limiting assembly 800.

[0125] It should be noted that the schematic diagram of the limiting cooperation between the input panel 510 and the first shell 120 through the limiting assembly 800 can refer to the cooperation relationship between the output panel 410 and the first shell 120 through the limiting assembly 800, which is not specifically shown in the figure.

[0126] In summary, the split panel and the first shell 120 are guided and matched through the guide component 700 and limited by the limit component 800 to maximize the connection quality between the split panel and the first shell 120 and reduce the difficulty of connection, so that the split panel and the first shell 120 form a detachable fit, which is convenient for assembling and disassembling the split panel, thereby achieving the purpose of quickly assembling, disassembling and replacing split panels of different specifications.

[0127] Through the above-mentioned setting, in a specific example, when the split panel and the first shell 120 need to be matched and connected, the split panel and the first shell 120 can first be guided by the guide component 700 to make the relative position of the split panel and the first shell 120 accurate, that is, the split panel can be accurately set on the first shell 120. After the split panel is assembled into place, the relative position of the split panel and the first shell 120 is limited by the limiting component 800 so that the split panel can be stably set on the first shell 120, thereby realizing the matched connection between the split panel and the first shell 120, and making the split panel and the first shell 120 form a detachable fit.

[0128] In some embodiments, combined Figure 8-Figure 22As shown, the limiting assembly 800 includes a limiting protrusion 810 and a limiting groove 820. The limiting protrusion 810 can be limitedly engaged within the limiting groove 820. One of the limiting protrusion 810 and the limiting groove 820 is located at the installation opening 121, and the other is located in the split panel. In this way, when the limiting protrusion 810 is limitedly engaged within the limiting groove 820, the split panel and the first shell 120 can be limitedly engaged, further reducing the difficulty of the split panel and the first shell 120. The relative position of the split panel and the first shell 120 is stabilized, thereby achieving a mating connection between the split panel and the first shell 120.

[0129] In some embodiments, combined Figure 13 and Figure 14 As shown, when the output panel 410 is a split panel, the limiting protrusion 810 is provided on the output panel 410, and the limiting groove 820 is provided at the mounting opening 121. In this way, when the limiting protrusion 810 is limitedly fitted in the limiting groove 820, the limiting fit of the output panel 410 and the first shell 120 can be achieved, thereby reducing the difficulty of limiting fit between the output panel 410 and the first shell 120 and making the relative position of the output panel 410 and the first shell 120 stable.

[0130] Of course, in some other embodiments, the limiting protrusion 810 may also be provided at the installation opening 121 , and the limiting groove 820 may be provided on the output panel 410 .

[0131] In some embodiments, when the input panel 510 is a split panel, the limiting protrusion 810 is provided on the input panel 510, and the limiting groove 820 is provided at the mounting port 121. In this way, when the limiting protrusion 810 is limitedly fitted in the limiting groove 820, the limiting fitting of the input panel 510 and the first shell 120 can be achieved, thereby reducing the difficulty of limiting fitting of the input panel 510 and the first shell 120 and making the relative position of the input panel 510 and the first shell 120 stable.

[0132] Of course, in some other embodiments, the limiting protrusion 810 may also be provided at the installation opening 121 , and the limiting groove 820 may be provided on the input panel 510 .

[0133] In some embodiments, combined Figure 18 、 Figure 19 、 Figure 21 and Figure 22 As shown, when the main control panel 610 is a split panel, the limiting protrusion 810 is provided on the main control panel 610, and the limiting groove 820 is provided at the installation port 121. In this way, when the limiting protrusion 810 is limited and matched in the limiting groove 820, the limiting matching of the main control panel 610 and the first shell 120 can be achieved, thereby reducing the difficulty of limiting matching of the main control panel 610 and the first shell 120 and making the relative position of the main control panel 610 and the first shell 120 stable.

[0134] Of course, in some other embodiments, the limiting protrusion 810 may also be provided at the installation opening 121 , and the limiting groove 820 may be provided on the main control panel 610 .

[0135] In some embodiments, the split panel and the first shell 120 are limited and matched through multiple limiting components 800 to improve the limiting effect of the limiting components 800, thereby facilitating the use of the limiting components 800 to achieve the matching connection between the split panel and the first shell 120, reducing the connection difficulty, improving the connection quality, and making the split panel and the first shell 120 form a detachable fit, reducing the difficulty of assembling and disassembling the split panel.

[0136] In some embodiments, combined Figure 8 、 Figure 9 、 Figure 18 and Figure 19 As shown, the limiting assembly 800 includes a limiting plate 830, which is connected to the first housing 120 and close to the mounting opening 121. The limiting groove 820 is formed on the limiting plate 830. This not only allows the limiting groove 820 to be positioned close to the mounting opening 121, but also reduces the difficulty of forming the limiting groove 820, thereby facilitating the limiting protrusion 810 provided on the split panel to be limitedly engaged within the limiting groove 820, thereby achieving the limited engagement of the split panel with the first housing 120 using the limiting assembly 800.

[0137] At the same time, by forming the limiting groove 820 on the limiting plate 830, it is also possible to avoid grooving on the first shell 120, thereby avoiding reducing the structural strength of the first shell 120, which is beneficial to ensuring the structural strength of the first shell 120 and extending the service life of the first shell 120.

[0138] It should be noted that when the limiting protrusion 810 is provided at the installation opening 121, the limiting plate 830 can be connected to the split panel. In this way, a limiting groove 820 is opened on the limiting plate 830, and the limiting protrusion 810 is limited and matched in the limiting groove 820. The limiting match between the split panel and the first shell 120 can also be achieved, and the difficulty of forming the limiting groove 820 is reduced.

[0139] In some embodiments, the limiting plate 830 is engaged with the bottom of the split panel. This facilitates the engagement of the limiting protrusion 810 within the limiting groove 820 to achieve the positional engagement of the split panel with the first housing 120. Furthermore, after the split panel is installed, the limiting plate 830 can be used to limit the position of the split panel, ensuring that the split panel can be accurately installed at the installation opening 121, thereby reducing the difficulty of installing the split panel.

[0140] At the same time, after the split panel is installed in place, by engaging the limit plate 830 with the bottom stop of the split panel, the limit plate 830 can also play the function of supporting and limiting the split panel, so as to support the split panel and improve the position stability of the split panel.

[0141] In some embodiments, the split panel moves from the top wall of the mounting opening 121 toward the bottom wall of the mounting opening 121 to be installed at the mounting opening 121, and the limiting plate 830 is provided on the bottom wall of the mounting opening 121. This means that during the installation of the split panel, when the split panel moves from the top wall of the mounting opening 121 toward the bottom wall of the mounting opening 121 for installation, the limiting plate 830 is provided on the bottom wall of the mounting opening 121 so as to achieve a stop fit between the limiting plate 830 and the bottom of the split panel, thereby facilitating the use of the limiting plate 830 to limit the position of the split panel, ensuring that the split panel can be accurately installed at the mounting opening 121, and reducing the difficulty of installing the split panel.

[0142] In some embodiments, the output panel 410 and the housing 100 are formed as a single piece (not shown in this example figure), and the output module 420 is detachably coupled to the output panel 410. That is, the output panel 410 is not limited to being a separate panel; the output panel 410 and the housing 100 can also be formed as a single piece, thereby eliminating the need for connection between the output panel 410 and the housing 100, reducing connection difficulty, and ensuring the strength of the connection between the output panel 410 and the housing 100. Furthermore, when the output panel 410 and the housing 100 are formed as a single piece, the output module 420 is detachably coupled to the output panel 410, facilitating removal of the output module 420 and thus facilitating replacement of output modules 420 of different specifications, thereby achieving a variety of output interfaces for the energy storage device 1000, meeting the switching of interface specifications in different countries, and expanding the scope of application of the energy storage device 1000.

[0143] The detachable connection between the output module 420 and the output panel 410 mentioned here may be a bolt connection, a snap connection, etc.

[0144] In some embodiments, the main control panel 610 is a split panel, and the main control panel 610 is fixedly connected to the housing 100 by a fastener 910 (the specific structure of the fastener 910 can be combined with the Figure 4 and Figure 5 Here, when the main control panel 610 and the housing 100 are formed as separate parts, the main control panel 610 is fixedly connected to the housing 100 by the fasteners 910. While achieving the fixed connection of the main control panel 610 to the housing 100, it can also reduce the difficulty of fixing the main control panel 610 and the housing 100 and ensure the quality of the connection, so that the main control panel 610 can be stably arranged on the housing 100, improve the position stability of the main control panel 610, and ensure the working performance of the main control assembly 600 to a certain extent.

[0145] In a specific example, the main control panel 610 is fixedly connected to the first shell 120 via fasteners 910 to achieve a fixed connection between the main control panel 610 and the housing 100 and reduce the difficulty of connection.

[0146] In summary, when the main control panel 610 is a split panel, the main control panel 610 is guided and matched with the first shell 120 through the guide component 700, limited and matched with the first shell 120 through the limit component 800, and fixedly connected with the first shell 120 through the fastener 910, so as to achieve a stable connection of the main control panel 610 to the first shell 120 and reduce the difficulty of fixed connection between the main control panel 610 and the outer shell 100.

[0147] In a specific example, when assembling the main control panel 610, the main control panel 610 is first guided by the guide component 700 to realize the assembly of the main control panel 610 to the first shell 120. After the main control panel 610 is assembled in place, the relative position of the main control panel 610 and the first shell 120 is limited by the limit component 800 so that the split panel can be stably arranged on the first shell 120. Finally, the main control panel 610 is fixedly connected to the outer shell 100 using the fastener 910 to realize the fixed connection between the main control panel 610 and the first shell 120, thereby improving the position stability of the main control panel 610 and making the main control panel 610 and the first shell 120 form a detachable fit.

[0148] It should be noted that, combined with Figure 2 、 Figure 8 、 Figure 9 and Figure 10 As shown, when the input panel 510 and the output panel 410 are formed as split panels, since the top wall of the mounting opening 121 for mounting the input panel 510 and the output panel 410 is open, in some embodiments, the opening can be set to face the second shell 130. In this way, when the input panel 510 and the output panel 410 are installed in place, the second shell 130 can be used to fix the input panel 510 and the output panel 410. This can eliminate the need to assemble the fasteners 910 after the input panel 510 and the output panel 410 are installed in place, thereby reducing the difficulty of assembling the input panel 510 and the output panel 410.

[0149] In some embodiments, combined Figure 15 、 Figure 17 、 Figure 18 and Figure 20As shown, the housing 100 is provided with a first mounting protrusion 122, and the main control panel 610 is provided with a second mounting protrusion 611 opposite the first mounting protrusion 122. Fasteners 910 are respectively fixedly connected to the first mounting protrusion 122 and the second mounting protrusion 611. This achieves the purpose of using fasteners 910 to securely connect the main control panel 610 to the housing 100, reduces the difficulty of securing the main control panel 610 to the housing 100, and improves the connection strength between the main control panel 610 and the housing 100.

[0150] In some embodiments, combined Figure 18 and Figure 20 As shown, the first mounting protrusion 122 is provided on the first shell 120. In this way, when the fastener 910 is fixedly connected to the first mounting protrusion 122 and the second mounting protrusion 611 respectively, the main control panel 610 and the first shell 120 can be fixedly connected, and then the main control panel 610 and the outer shell 100 can be fixedly connected, thereby reducing the difficulty of fixing the main control panel 610 and the outer shell 100.

[0151] The fastener 910 mentioned above may be a fastening screw, a fastening bolt, etc.

[0152] Of course, in some other embodiments, the fastener 910 can also be formed as a fastening buckle (not shown in this example figure). When the fastener 910 is formed as a fastening buckle, the fastening buckle is provided on one of the main control panel 610 and the first shell 120, and the other of the main control panel 610 and the first shell 120 is provided with a fastening groove that cooperates with the fastening buckle. The fastening buckle is snapped into the fastening groove, which can also realize the fixed connection between the main control panel 610 and the first shell 120, and then realize the fixed connection between the main control panel 610 and the outer shell 100.

[0153] In some embodiments, combined Figure 2 and Figure 23 As shown, the input assembly 500 includes a protective member 530, which is rotatably mounted on the input panel 510 so that the protective member 530 has a first position for protecting the input module 520 and a second position for exposing the input module 520. This allows the protective member 530 to both protect the input module 520 and expose it. When the protective member 530 protects the input module 520, it prevents damage to the input module 520, thereby extending its service life. It also prevents users from accidentally touching the input module 520, improving the safety of the energy storage device 1000. When the protective member 530 rotates to expose the input module 520, it facilitates access to the input module 520, ensuring the performance of the energy storage device 1000.

[0154] That is to say, the present application rotatably arranges the protective member 530 on the input panel 510 , which can protect the input module 520 while preventing the protective member 530 from affecting the normal use of the input module 520 .

[0155] It should be noted that Figure 23 The guard 530 is shown in the second position.

[0156] In some embodiments, the protective member 530 is rotatably disposed on a side of the input panel 510 facing away from the accommodating cavity 110 , so that the protective member 530 can be used to protect the input module 520 .

[0157] It should also be noted that whether a protective structural member for protecting the output module 420 is provided on the output component 400 can be selectively provided according to the requirements of different countries, and this application does not impose any specific restrictions.

[0158] In some embodiments, as Figure 23 and Figure 25 As shown, the protective member 530 is a protective plate. A rotatable connecting plate 531 is provided on the side of the protective plate facing the input panel 510. The input panel 510 is provided with an escape groove 511 for circumventing the rotatable connecting plate 531. The rotatable connecting plate 531 is rotatably connected within the escape groove 511 via a rotating shaft 540. This allows the protective plate and the input panel 510 to rotate in conjunction with each other, and thus the protective member 530 and the input panel 510 to rotate in conjunction with each other, enabling the protective member 530 to switch between a first position and a second position. This allows the protective member 530 to protect the input module 520 while preventing it from interfering with the normal operation of the input module 520.

[0159] In some embodiments, as Figure 26 As shown, a mating groove 513 is provided in the avoidance groove 511, and the rotating shaft 540 is provided on the rotating connecting plate 531. The rotating connecting plate 531 is connected in the avoidance groove 511 and the rotating shaft 540 is rotatably matched with the mating groove 513 to realize the rotational connection between the protective member 530 and the input panel 510, and reduce the difficulty of the rotational connection between the protective member 530 and the input panel 510.

[0160] Among them, the rotating shaft 540 mentioned here can be understood as a tenon, and the matching groove 513 can be understood as a mortise. The tenon on the rotating connecting plate 531 is matched with the mortise on the input panel 510 to realize the rotation function of the rotating connecting plate 531, so that the protective member 530 can effectively switch between the first position and the second position.

[0161] In some embodiments, rotating connecting plates 531 are provided on opposite sides of the protective member 530, and the two rotating connecting plates 531 are respectively rotatably connected in the avoidance groove 511 through the rotating shaft 540 to increase the rotational connection strength between the protective member 530 and the input panel 510, thereby preventing the protective member 530 from being removed from the input panel 510, thereby facilitating the use of the protective member 530 to protect the input module 520.

[0162] It should be noted that by setting the protective member 530 as a protective plate, while reducing the difficulty of molding the protective member 530, it is also convenient to use the protective member 530 to protect the input module 520, thereby extending the service life of the input module 520 and improving the safety of the energy storage device 1000.

[0163] In some embodiments, combined Figure 23 、 Figure 24 、 Figure 25 and Figure 26 As shown, the avoidance groove 511 is an arcuate groove, and the side of the rotatable connecting plate 531 facing the avoidance groove 511 is an arcuate surface. This helps increase the rotation angle of the protective member 530 when the protective member 530 rotates relative to the input panel 510, especially when the protective member 530 rotates from the first position to the second position. This helps to prevent the protective member 530 from blocking the input module 520 to a certain extent and prevents the protective member 530 from occupying too much space on the outside of the input panel 510. This facilitates the use of the input module 520 and reduces the difficulty of using the input module 520.

[0164] In some embodiments, combined Figure 23 、 Figure 25 and Figure 26 As shown, a fixing assembly 550 is provided between the protective member 530 and the input panel 510. The fixing assembly 550 is used to position the protective member 530 to a first position. While the protective member 530 protects the input module 520, it also stabilizes the position of the protective member 530 while protecting the input module 520. This allows the protective member 530 to effectively protect the input module 520 and extend the service life of the input module 520.

[0165] In some embodiments, combined Figure 23 、 Figure 25 and Figure 26As shown, the fixing assembly 550 includes a metal member 551 and a magnet 552 that are magnetically engaged. One of the metal member 551 and the magnet 552 is disposed on the protective member 530, and the other is disposed on the input panel 510. Thus, when the metal member 551 and the magnet 552 are magnetically engaged, the fixing assembly 550 can be used to securely engage the protective member 530 and the input panel 510, thereby positioning the protective member 530 in the first position. This ensures that the protective member 530 maintains a stable position when protecting the input module 520, thereby effectively protecting the input module 520 and extending the service life of the input module 520.

[0166] In some embodiments, combined Figure 23 、 Figure 25 and Figure 26 As shown, the metal piece 551 is provided on the protective piece 530 , and the magnet 552 is provided on the input panel 510 . The metal piece 551 and the magnet 552 are magnetically coupled to achieve positioning and coupling between the protective piece 530 and the input panel 510 .

[0167] Of course, in some other embodiments, the metal part 551 may also be provided on the input panel 510, and the magnet 552 may be provided on the protective part 530. In this way, when the metal part 551 and the magnet 552 are magnetically coupled, the protective part 530 and the input panel 510 can also be fixedly coupled.

[0168] In some embodiments, as Figure 25 As shown, the metal part 551 is arranged on the protective part 530 through the glue column 553 to achieve fixed connection of the metal part 551 to the protective part 530, improve the connection strength between the metal part 551 and the protective part 530, and reduce the difficulty of connection.

[0169] In some embodiments, the metal member 551 and the adhesive column 553 are assembled by a hot stamping process, so that the metal member 551 is positioned on the protective member 530 by using the adhesive column 553 and the connection strength between the metal member 551 and the protective member 530 is improved.

[0170] In some embodiments, as Figure 25 As shown, the input panel 510 is provided with an assembly groove 512 , and the magnet 552 is disposed in the assembly groove 512 , so as to achieve the arrangement of the magnet 552 on the input panel 510 and reduce the difficulty of connecting the magnet 552 to the input panel 510 .

[0171] In some embodiments, the magnet 552 and the assembly groove 512 are assembled through interference fit to ensure that the magnet 552 is stably set in the assembly groove 512, that is, the magnet 552 is stably set on the input panel 510, thereby improving the position stability of the magnet 552 and ensuring the working performance of the magnet 552 to a certain extent.

[0172] Among them, the magnet 552 is arranged in the assembly groove 512 and can be bonded, welded or bolted to the assembly groove 512 to improve the connection strength between the magnet 552 and the input panel 510, so that the magnet 552 can stabilize the input panel 510, thereby facilitating the use of the metal part 551 and the magnet 552 to achieve fixed matching between the protective part 530 and the input panel 510, improving the position stability of the protective part 530 when it is in the first position, and ensuring the working performance of the protective part 530 to a certain extent.

[0173] In some embodiments, combined Figure 2 、 Figure 3 and Figure 4 As shown, a plurality of interfaces 621 are provided on the circuit board 620, and a plurality of avoidance openings 612 for avoiding the interfaces 621 are provided on the main control panel 610. The plurality of interfaces 621 include a DC power output interface 6211, a USB-A interface 6212, a USB-C interface 6213 and a cigarette lighter interface 6214. That is to say, the circuit board 620 is provided with a DC power output interface 6211, a USB-A interface 6212, a USB-C interface 6213 and a cigarette lighter interface 6214, and the main control panel 610 is provided with multiple avoidance openings 612 for avoiding the DC power output interface 6211, the USB-A interface 6212, the USB-C interface 6213 and the cigarette lighter interface 6214, so that the DC power output interface 6211, the USB-A interface 6212, the USB-C interface 6213 and the cigarette lighter interface 6214 can be exposed from the main control panel 610, thereby facilitating the connection of the power load to the DC power output interface 6211, the USB-A interface 6212, the USB-C interface 6213 or the cigarette lighter interface 6214, thereby ensuring the working performance of the DC power output interface 6211, the USB-A interface 6212, the USB-C interface 6213 and the cigarette lighter interface 6214 to a certain extent.

[0174] It should be noted that the DC power output interface 6211 is mainly used by devices such as electric guitars, surveillance cameras, some set-top boxes, LED desk lamps and digital appliances; the USB-A interface 6212 is a commonly used USB interface type, mainly providing charging and data transmission functions for handheld devices such as mobile phones, tablets, and mobile power supplies; the USB-C interface 6213 is a new type of USB interface type with a smaller size and stronger data transmission and charging capabilities, and the USB-C interface 6213 supports reversible plug-in design, which is convenient for users to use; the cigarette lighter interface 6214 is mainly used by devices such as car refrigerators, car fans or car vacuum cleaners.

[0175] At the same time, by setting a DC power output interface 6211, a USB-A interface 6212, a USB-C interface 6213 and a cigarette lighter interface 6214, the number of interfaces 621 on the main control component 600 can be increased and the diversity of the interfaces 621 can be met to meet market demand.

[0176] In some embodiments, combined Figure 2 、 Figure 3 and Figure 4 As shown, the multiple avoidance ports 612 on the main control panel 610 include a first avoidance port 6121, a second avoidance port 6122, a third avoidance port 6123 and a fourth avoidance port 6124. The first avoidance port 6121 is used to avoid the DC power output interface 6211, the second avoidance port 6122 is used to avoid the USB-A interface 6212, the third avoidance port 6123 is used to avoid the USB-C interface 6213, and the fourth avoidance port 6124 is used to avoid the cigarette lighter interface 6214, so that the DC power output interface 6211, the USB-A interface 6212, the USB-C interface 6213 and the cigarette lighter interface 6214 can be exposed from the main control panel 610, so as to facilitate connecting the electrical load to the DC power output interface 6211, the USB-A interface 6212, the USB-C interface 6213 or the cigarette lighter interface 6214.

[0177] In some embodiments, combined Figure 2 、 Figure 3 and Figure 4 As shown, the first avoidance port 6121 is arranged opposite to the DC power output interface 6211, the second avoidance port 6122 is arranged opposite to the USB-A interface 6212, the third avoidance port 6123 is arranged opposite to the USB-C interface 6213, and the fourth avoidance port 6124 is arranged opposite to the cigarette lighter interface 6214. In this way, after the main control panel 610 and the circuit board 620 are assembled in place, the avoidance port 612 can avoid the interface 621.

[0178] In some embodiments, combined Figure 2 、 Figure 3 and Figure 4 As shown, the main control panel 610 and the circuit board 620 are connected by multiple second screws 640. While achieving the coordinated connection between the main control panel 610 and the circuit board 620, it can also reduce the connection difficulty and improve the connection quality, so that the main control panel 610 and the circuit board 620 can form a stable connection, improve the structural stability of the main control component 600, and ensure the working performance of the main control component 600 to a certain extent.

[0179] In some embodiments, as Figure 4As shown, the DC power output interface 6211, the USB-A interface 6212 and the USB-C interface 6213 each include two, so as to increase the number of DC power output interfaces 6211, the USB-A interface 6212 and the USB-C interface 6213 to meet the use of multiple loads and thus meet market demand.

[0180] It should be noted that when the DC power output interface 6211, the USB-A interface 6212 and the USB-C interface 6213 each include two, the first avoidance port 6121, the second avoidance port 6122 and the third avoidance port 6123 also include two, so as to avoid the DC power output interface 6211, the USB-A interface 6212 and the USB-C interface 6213 respectively.

[0181] In some embodiments, combined Figure 4 and Figure 27 As shown, a snap-on portion 614 is provided on one side of the main control panel 610 facing the circuit board 620 , and the snap-on portion 614 snaps into engagement with the cigarette lighter interface 6214 to secure the cigarette lighter interface 6214 , thereby ensuring to a certain extent that the cigarette lighter interface 6214 can be assembled in place and used normally.

[0182] In some embodiments, combined Figure 3 、 Figure 4 、 Figure 27 and Figure 28 As shown, the main control panel 610 is provided with a plurality of buttons 613, which are connected to the main control panel 610 via a connecting arm 630 so that the buttons 613 can be movably matched with the main control panel 610. Thus, when the main control assembly 600 is in use, the user can press the buttons 613 and control the movement of the buttons 613, so as to use the buttons 613 to quickly cut off the electrical connection between the energy storage device 1000 and the power grid or other devices, use the buttons 613 to control the output of the DC power supply in the energy storage device 1000, and use the buttons 613 to control the muting of multimedia devices electrically connected to the energy storage device 1000, etc., thereby ensuring that the energy storage device 1000 can operate safely and efficiently, and providing strong support for the stable operation of the power system and the efficient use of energy.

[0183] In some embodiments, combined Figure 2 、 Figure 3 and Figure 4As shown, multiple buttons 613 include a DC switch button 6131, a POWER button 6132, a Mute button 6133, an IOT button 6134 and a Light button 6135, wherein the DC switch button 6131 is used to control the output of the DC power supply in the energy storage device 1000; the POWER button 6132 is used to control the main power switch of the energy storage device 1000, and pressing the POWER button 6132 can turn on or off the entire energy storage device 1000; the Mute button 6133 is used to control a multimedia device (such as an audio system) connected to the energy storage device 1000 to mute the audio output of the multimedia device; the IOT button 6134 is used to control the connection and interaction between the energy storage device 1000 and the Internet of Things system; and the Light button 6135 is used to control the lighting function on the energy storage device 1000, so that the energy storage device 1000 can operate safely and efficiently.

[0184] In summary, the main control component 600 of the present application integrates two DC power output interfaces 6211, two USB-A interfaces 6212, two USB-C interfaces 6213 and a cigarette lighter interface 6214, and also integrates related buttons 613 to form an integrated main control component 600.

[0185] In some embodiments, the DC switch button 6131, the POWER button 6132, the Mute button 6133 and the IOT button 6134 are all connected to the main control panel 610 through the connecting arm 630, and the Light button 6135 is directly and movably installed on the lighting system so that multiple buttons 613 can be used normally.

[0186] In a specific embodiment, one end of the connecting arm 630 is connected to the button 613, and the other end of the connecting arm 630 is first positioned and pre-assembled with the main control panel 610 through the connecting column 650, and then the connecting column 650 is hot-ironed to achieve the matching connection between the connecting column 650 and the main control panel 610, ensuring that the button 613 is assembled in place and functions normally, thereby forming the main control component 600, which facilitates the assembly, testing and maintenance of the main control component 600.

[0187] In some embodiments, combined Figure 27 and Figure 28 As shown, the connecting arm 630 has at least one bent portion 631. The bent portion 631 allows the connecting arm 630 to move relative to the main control panel 610 when a force is applied, thereby increasing the travel of movement, thereby increasing the travel of movement of the button 613 relative to the main control panel 610, so that the button 613 can effectively move relative to the main control panel 610, ensuring the working performance of the button 613 to a certain extent.

[0188] It should be noted that the POWER button 6132 , the Mute button 6133 and the IOT button 6134 can be connected to the main control panel 610 through separate connecting arms 630 respectively, or they can share the connecting arm 630 .

[0189] In some embodiments, combined Figure 1 、 Figure 2 and Figure 29 As shown, the energy storage device 1000 further includes a heat dissipation assembly 300 for dissipating heat from the inverter 210. This allows the large amount of heat generated by the inverter 210 during operation to be dissipated promptly and effectively, thereby preventing damage to internal components of the inverter 210 due to the heat to a certain extent and extending the service life of the inverter 210.

[0190] In some embodiments, the heat dissipation assembly 300 may be used to dissipate heat from the battery pack 220 , thereby improving the safety of the battery pack 220 and extending the service life of the battery pack 220 .

[0191] In some embodiments, combined Figure 1 、 Figure 2 and Figure 29 As shown, the housing 100 and / or the split panel are provided with an air vent 920 that communicates with the accommodating cavity 110. The heat dissipation assembly 300 includes a heat sink 310 and a heat dissipation fan 320. The heat sink 310 exchanges heat with the inverter 210. The heat dissipation fan 320 is used to direct air from outside the accommodating cavity 110 to the heat sink 310 through the air vent 920, and to dissipate heat from the heat sink 310 to the outside of the accommodating cavity 110 through the air vent 920. In this way, air from the outside can flow through the heat sink 310 to dissipate heat from the heat sink 310. At the same time, the hot air dissipated by the heat sink 310 can be discharged through the air vent 920, thereby dissipating heat from the inverter 210, ensuring heat dissipation quality, and extending the service life of the inverter 210.

[0192] In some embodiments, as Figure 29As shown, the cooling fans 320 include multiple cooling fans 320, which are spaced apart at opposite ends of the heat dissipation plate 310. The air outlet 920 includes an air inlet 921 and an air outlet 922. One of the air inlet 921 and the air outlet 922 is provided on the output panel 410, and the other is provided on the input panel 510. The air inlet 921 faces one of the cooling fans 320, and the air outlet 922 faces the other cooling fan 320. In this way, when the cooling fan 320 facing the air inlet 921 is running, the external air can be drawn out through the air inlet 921 and led to the heat sink 310, so as to realize the heat dissipation on the heat sink 310 and ensure the heat exchange effect between the heat sink 310 and the inverter 210. At the same time, when the cooling fan 320 facing the air outlet 922 is running, the air drawn out from the heat sink 310 can be guided to the outside of the accommodating cavity 110 through the air outlet 922, so as to achieve the purpose of dissipating heat for the inverter 210, ensure the heat dissipation quality, and extend the service life of the inverter 210.

[0193] It should be noted that by providing multiple cooling fans 320 , the cooling effect can be effectively improved.

[0194] In some embodiments, as Figure 29 As shown, the heat dissipation plates 310 include a plurality of heat dissipation plates 310 , and the plurality of heat dissipation plates 310 respectively exchange heat with the inverter 210 to further improve the heat dissipation effect of the inverter 210 .

[0195] In a specific example, an air inlet 921 is provided on the input panel 510, and an air outlet 922 is provided on the output panel 410. A heat dissipation duct is formed between the air inlet 921 and the air outlet 922. The inverter 210 is arranged in the heat dissipation duct, and two heat dissipation fans 320 are arranged at opposite ends of the heat dissipation plate 310. The fan facing the air inlet 921 is formed as an air inlet fan, and the fan facing the air outlet 922 is formed as an air outlet fan, so as to achieve heat dissipation of the inverter 210 and extend the service life of the inverter 210.

[0196] In some embodiments, as Figure 29 As shown, the energy storage device 1000 includes a bracket 230, which is fixed in the accommodating cavity 110. The inverter 210 is arranged on the bracket 230, so as to utilize the bracket 230 to support the inverter 210, improve the position stability of the inverter 210, and ensure the working performance of the inverter 210 to a certain extent.

[0197] In some embodiments, as Figure 29 As shown, mounting grooves 231 are provided at opposite ends of the bracket 230, and the cooling fan 320 is assembled at the corresponding mounting groove 231 position by a third screw 232, and cooperates with the heat dissipation plate 310 of the inverter 210 to form a heat dissipation duct, ensuring that the heat dissipation component 300 has good heat dissipation performance and maintaining the normal operation of the inverter 210.

[0198] In some embodiments, combined Figure 1 、 Figure 2 and Figure 30 As shown, the housing 100 is provided with a handle 140. The handle 140 facilitates the user to hold the energy storage device 1000, thereby facilitating the movement of the energy storage device 1000, reducing the difficulty of moving the energy storage device 1000, and facilitating the use of the energy storage device 1000.

[0199] In some embodiments, combined Figure 1 、 Figure 2 and Figure 30 As shown, the handle portion 140 is disposed on the second shell 130 , which not only realizes the arrangement of the handle portion 140 on the housing 100 , but also reduces the difficulty of connecting the handle portion 140 and the housing 100 .

[0200] In some embodiments, combined Figure 30 、 Figure 31 and Figure 32 As shown, the handle portion 140 includes a bottom shell 141 and a cover plate 142 connected to the bottom shell 141. The combination of the bottom shell 141 and the cover plate 142 not only reduces the difficulty of molding the handle portion 140, but also allows the handle portion 140 to have a certain radial dimension, making it easier for the user to hold the handle portion 140 to carry the energy storage device 1000, thereby reducing the difficulty of moving the energy storage device 1000.

[0201] In some embodiments, combined Figure 1 、 Figure 2 and Figure 30 As shown, the second shell 130 includes a bottom shell 141 and a cover plate 142 , which cooperate to form the second shell 130 , thereby reducing the difficulty of molding the second shell 130 , ensuring the structural strength of the second shell 130 , and extending the service life of the second shell 130 .

[0202] In some embodiments, combined Figure 1 、 Figure 2 and Figure 30 As shown, at least parts of the bottom shell 141 and the cover plate 142 protrude upward and are connected to each other to form a handle portion 140. While reducing the difficulty of molding the handle portion 140, the handle portion 140 can also be formed into an integral piece with the second shell 130, so that the energy storage device 1000 can be carried by using the handle portion 140.

[0203] Of course, in some other embodiments, the handle portion 140 may also be rotatably connected to the second shell 130 to form a foldable handle portion 140 .

[0204] In a specific example, the U-shaped handle and the second shell 130 are processed and formed separately, the handle portion 140 is designed as a U-shaped handle, and the assembly part of the U-shaped handle and the second shell 130 is designed as a rotating shaft structure to ensure the rotation of the U-shaped handle, thereby realizing the function of folding the U-shaped handle.

[0205] It should be noted that when the handle portion 140 is rotatably connected to the second shell 130 to form a foldable handle portion 140 , the second shell 130 may only include the bottom shell 141 or the cover plate 142 , thereby reducing the difficulty of molding the second shell 130 .

[0206] In some embodiments, when the handle portion 140 and the second housing 130 include a bottom shell 141 and a cover plate 142, the combination Figure 30 、 Figure 31 and Figure 32 As shown, the cover plate 142 is provided with a second buckle 1421, and the bottom shell 141 is provided with a second slot 1411. The second buckle 1421 is snap-fitted into the second slot 1411 to achieve a mating connection between the bottom shell 141 and the cover plate 142, reducing the difficulty of connection.

[0207] Among them, the second buckle 1421 mentioned here can be understood as a buckle.

[0208] Of course, in some other embodiments, a second card slot 1411 may be provided on the cover plate 142 , and a second buckle 1421 may be provided on the bottom shell 141 , and the second buckle 1421 may be snap-fitted into the second card slot 1411 , thereby achieving snap-fitting of the bottom shell 141 and the cover plate 142 .

[0209] In some embodiments, as Figure 30 As shown, the second shell 130 further includes a fourth screw 143 , and the bottom shell 141 and the cover plate 142 are connected by the fourth screw 143 to achieve a fixed connection between the bottom shell 141 and the cover plate 142 and improve the connection strength.

[0210] In some embodiments, as Figure 30 As shown, the fourth screws 143 include a plurality of screws. The cooperation of the plurality of fourth screws 143 can increase the connection strength between the bottom shell 141 and the cover plate 142 , thereby improving the structural stability of the second shell 130 .

[0211] Through the above arrangement, during the assembly process of the second shell 130, the bottom shell 141 and the cover plate 142 can be snap-fitted together by the cooperation of the second clip 1421 and the second slot 1411. After the assembly is completed, they are tightened by the fourth screw 143 to ensure that the bottom shell 141 and the cover plate 142 are assembled in place to form a modular second shell 130, which facilitates the subsequent assembly and replacement of version materials of the second shell 130.
