[0084] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The energy storage power supply 100 of the embodiment of the present invention includes a housing 10, a circuit board module 20 and a battery module 30. The housing 10 includes a first housing 11 and a second housing 12 detachably connected to the first housing 11, and the first housing 11 and the second housing 12 enclose a receiving chamber 13; the circuit board module 20 includes an inverter circuit 2141 (such as Figure 10a ), the circuit board module 20 is fixedly mounted on the first shell 11 and is located in the accommodating chamber 13; the battery module 30 is fixedly mounted on the second shell 12 and is located in the accommodating chamber 13, and the battery module 30 is electrically connected to the circuit board module 20.

[0085] In the energy storage power supply 100 according to the embodiment of the present invention, a modular design of the energy storage power supply 100 is achieved by designing the housing 10 as a detachable first housing 11 and a second housing 12, and fixing the circuit board module 20 and the battery module 30 to the corresponding housings. This design allows for the pre-assembly of the circuit board module 20 with the first housing 11, and the battery module 30 with the second housing 12, during the assembly process. The circuit board module 20 and the first housing 11, and the battery module 30 and the second housing 12 can then be combined as a whole. This simplifies the overall assembly process, significantly reduces assembly complexity, and significantly improves assembly efficiency.

[0086] Specifically, the housing 10 is the outer protective structure of the energy storage power supply 100, used to accommodate and protect the internal components. The housing 10 contains the battery module 30 and the circuit board module 20. The housing 10 can be made of metal, plastic or other composite materials.

[0087] The removable connection between the first housing 11 and the second housing 12 can be a bolted connection, a snap-fit ​​connection, or a plug-in connection. The accommodating chamber 13 is an internal space enclosed by the first housing 11 and the second housing 12. The accommodating chamber is used to accommodate the circuit board module 20 and the battery module 30, providing a protected internal environment.

[0088] The circuit board module 20 is the control and management core of the energy storage power supply 100 and contains various electronic components and control circuits. The circuit board module 20 is used to convert, control, and manage electrical energy, ensuring the proper operation of the energy storage power supply 100. The circuit board module 20 can be fixedly mounted to the first housing 11 using bolts, snap-fit ​​connections, or plug-in connections.

[0089] The inverter circuit 2141 is a circuit that converts direct current (DC) into alternating current (AC). This allows the energy storage power supply 100 to adapt to different power requirements. It can convert DC power from the battery module 30 for external AC output, and it can also convert external AC input into DC power to power the battery module 30.

[0090] The battery module 30 is the energy storage unit of the energy storage power supply 100 and may include multiple battery cells 32. The battery module 30 is used to store electrical energy and provide energy support for the output of the energy storage power supply 100. The battery module 30 can be a lithium-ion battery, a lead-acid battery, or another type of battery, depending on the energy storage requirements and application scenario. The battery module 30 can be fixedly mounted to the second housing 12 using bolts, snap-fit ​​connections, or plug-in connections.

[0091] Electrical connection refers to establishing an electrical pathway between the circuit board module 20 and the battery module 30 through electrical components such as wires and connectors, enabling the transmission of electrical energy and signals between the circuit board module 20 and the battery module 30. This electrical connection enables the circuit board module 20 to control and manage the battery module 30, ensuring stable transmission of electrical energy. The electrical connection between the circuit board module 20 and the battery module 30 can be achieved through welding, bolting, terminal blocks, or wire connections.

[0092] Please refer to Figure 5 、 Figure 6 and Figure 7 During assembly, the circuit board module 20 can first be fixedly mounted on the first housing 11, and the battery module 30 can be fixedly mounted on the second housing 12. The first and second housings 11, 12 can then be detachably connected to form the complete housing 10, forming the receiving chamber 13. Finally, the circuit board module 20 and the battery module 30 can be electrically connected to complete the assembly of the energy storage power supply 100.

[0093] During use, the battery module 30 stores electrical energy and transmits the electrical energy to the circuit board module 20 through electrical connections. The circuit board module 20 converts, controls, and manages the electrical energy to ensure stable output of the electrical energy.

[0094] Please refer to Figure 1 and Figure 4In some embodiments, the first housing 11 is formed with a vent 110 communicating with the accommodating chamber 13 .

[0095] In this way, by providing the vents 110 on the first shell 11, air circulation can be promoted, effectively reducing the temperature in the accommodating chamber 13, thereby improving the heat dissipation performance of the energy storage power supply 100, thereby improving the operating stability of the energy storage power supply 100 and extending the service life of the internal components of the energy storage power supply 100.

[0096] Specifically, the vents 110 are openings provided on the first housing 11 for promoting air circulation. The vents 110 can be designed in a louvered, meshed, or other form to prevent foreign matter from entering the interior of the device. The number of vents 110 can be one or more. For example, there can be two vents 110, which are spaced apart and provided on the first housing 11. The shape of the vents 110 can be regular, such as circular or square, or irregular.

[0097] Please refer to Figure 4 In some embodiments, the vent 110 includes an air inlet 1100 and an air outlet 1101 , and the air inlet 1100 and the air outlet 1101 are respectively located on opposite sides of the first housing 11 .

[0098] In this way, the air inlet 1100 and the air outlet 1101 are respectively located on opposite sides of the first shell 11. This design forms a longer air flow path, allowing air to flow through most areas inside the energy storage power supply 100, thereby significantly improving the heat dissipation efficiency.

[0099] Specifically, the two opposite sides may be the front and back sides, left and right sides, or top and bottom sides of the energy storage power supply 100. For example, for a rectangular parallelepiped energy storage power supply 100, the air inlet 1100 and the air outlet 1101 may be disposed on the left and right sides of the energy storage power supply 100, or in other words, the air inlet 1100 and the air outlet 1101 may be disposed at intervals along the length direction of the energy storage power supply 100.

[0100] Please refer to Figure 1 、 Figure 2 and Figure 8 In some embodiments, the first housing 11 includes a first substrate 111 and a panel 112 connected to the first substrate 111 , the panel 112 is connected to the second housing 12 , and the circuit board module 20 is at least partially fixedly mounted on the first substrate 111 .

[0101] Thus, by designing the first housing 11 as a combination of a first substrate 111 and a panel 112, the circuit board module 20 can be pre-installed on the first substrate 111, and then the panel 112 and the second housing 12 can be assembled into a complete housing. This step-by-step assembly method simplifies the assembly process, reduces assembly complexity, and improves assembly efficiency.

[0102] Specifically, the first substrate 111 is a part of the first housing 11 and can be a flat plate-like structure. The shape of the first substrate 111 can be a regular shape such as a rectangle or a circle, or it can be an irregular shape. For example, the shape of the first substrate 111 is a rectangle. The first substrate 111 can be directly connected to the panel 112, or it can be spaced apart from the panel 112 and indirectly connected through other structures. The first substrate 111 can be provided with mounting holes, slots, and other structures for fixing and installing the circuit board module 20. The circuit board module 20 can be fixedly mounted on the first substrate 111 by means of bolt connection, snap connection, or plug connection.

[0103] Panel 112 is another portion of first housing 11 and can be a flat, plate-like structure. Panel 112 can be regular, such as rectangular or circular, or irregular. For example, panel 112 is rectangular. Panel 112 can be connected to second housing 12 via bolts, snap-fit ​​connections, or plug-in connections.

[0104] Please refer to Figure 2 and Figure 9 In some embodiments, the circuit board module 20 includes a first circuit board 21 and a second circuit board 22 electrically connected to the first circuit board 21 , the first circuit board 21 is fixedly mounted on the first substrate 111 , and the second circuit board 22 is fixed on the panel 112 .

[0105] In this way, by dividing the circuit board module 20 into the first circuit board 21 and the second circuit board 22, and fixing them respectively on the first substrate 111 and the panel 112, a distributed installation of the circuit boards can be achieved. This distributed installation method allows different circuit board parts to be handled separately during the assembly process, thereby simplifying the assembly steps and improving assembly efficiency.

[0106] Specifically, the first circuit board 21 and the second circuit board 22 are two different parts of the circuit board module 20. The first circuit board 21 and the second circuit board 22 can be connected at a predetermined angle. For example, the angle between the first circuit board 21 and the second circuit board 22 can be 45 degrees, 60 degrees, 90 degrees, or other angles.

[0107] The first circuit board 21 and the second circuit board 22 can be electrically connected by welding, bolt connection, terminal connection, or wire connection.

[0108] In some embodiments, the first circuit board 21 is fixed to the first substrate 111 by screws.

[0109] In some embodiments, the second circuit board 22 is fixed to the panel 112 by screws.

[0110] In some embodiments, the first circuit board 21 is fixed to the first substrate 111 by screws, and the second circuit board 22 is fixed to the panel 112 by screws.

[0111] Screw fastening provides a secure mechanical connection, ensuring the circuit board remains stable even in challenging environments like vibration and shock, preventing electrical failures caused by loose connections. Furthermore, screw fastening is a common fastening method, with readily available tools and simple operation, making installation and maintenance easy. When replacing or repairing a circuit board, simply loosening the screws allows for removal, improving maintenance efficiency.

[0112] Specifically, the number of screws can be one or more, such as two, three, four, or even more. Multiple screws provide multiple connection points, thereby enhancing the connection strength. Screw fixation can be combined with accessories such as washers and spring washers to enhance the fixing effect.

[0113] Please refer to Figure 1 and Figure 9 In some embodiments, the panel 112 is provided with an opening 112a. The first circuit board 21 and the second circuit board 22 are arranged at a certain angle. The first circuit board 21 includes an inverter circuit 2141. The second circuit board 22 includes an output port 102a. The output port 102a is directly opposite the opening 112a.

[0114] In this way, the output port 102 a faces the open port 112 a on the panel 112 , which facilitates the user to directly make external connections through the open port 112 a without the need for additional adapters or complicated wiring, thereby enhancing the user experience.

[0115] Specifically, the angle between the first circuit board 21 and the second circuit board 22 may be 30 degrees, 60 degrees, 90 degrees, 120 degrees, or the like.

[0116] The opening 112a may be an opening on the panel 112. The number of the opening 112a may be one or more, and the number of the openings 112a may correspond to the number of the output ports 102a.

[0117] The output port 102 a may be a USB port 101 or a vehicle charging port 102 .

[0118] Please refer to Figure 2 and Figure 9In some embodiments, the first circuit board 21 is arranged horizontally and the second circuit board 22 is arranged vertically.

[0119] By arranging the first circuit board 21 horizontally and the second circuit board 22 vertically, the three-dimensional space within the energy storage power supply 100 can be more effectively utilized, avoiding overlap and interference between the circuit boards, thereby improving space utilization. Furthermore, this horizontal and vertical layout facilitates installation and maintenance of the circuit boards. Maintenance personnel can more easily access and operate the different circuit boards without having to disassemble other components, improving maintenance efficiency.

[0120] Specifically, the horizontal arrangement means that the first circuit board 21 is installed in a horizontal direction. By being arranged in a horizontal direction, the first circuit board 21 can more effectively utilize the horizontal space and avoid interference with other components.

[0121] The vertical arrangement means that the second circuit board 22 is installed in a vertical direction. By vertically arranging, the second circuit board 22 can more effectively utilize the vertical space and optimize the overall layout.

[0122] Please refer to Figure 2 In some embodiments, the first circuit board 21 and the second circuit board 22 are both fixed to the first housing 11 .

[0123] In this way, the first circuit board 21 and the second circuit board 22 are fixed on the first housing 11. This fixing method helps to maintain a reasonable layout between the circuit boards, avoid overlap and interference between the circuit boards, and further improve the utilization rate of the internal space of the energy storage power supply 100.

[0124] If the first and second housings 11, 12 were not removable, the second housing 12 would interfere with the installation of the first and second circuit boards 21, 22. Therefore, the removable first and second housings 11, 12 allow the first and second circuit boards 21, 22 to be pre-attached to the first housing 11 before the second housing 12 is connected to the first housing 11, completing the assembly of the entire energy storage power supply 100. This modular design improves production efficiency and reduces assembly time.

[0125] Specifically, the first circuit board 21 and the second circuit board 22 can be fixed to the first housing 11 by bolt connection, snap connection, plug connection or the like.

[0126] Please refer to Figure 10 In some embodiments, one of the first circuit board 21 and the second circuit board 22 is provided with a plug-in hole 210, and the other is provided with a plug-in protrusion 220, which is inserted into the plug-in hole 210 to fix the first circuit board 21 and the second circuit board 22 in connection.

[0127] Thus, the design of the plug hole 210 and the plug protrusion 220 allows for quick connection and disassembly between circuit boards without the use of tools, thereby significantly improving the efficiency of assembly and maintenance.

[0128] Specifically, the insertion hole 210 is an opening or recess provided on the circuit board for accommodating the insertion protrusion 220. The insertion hole 210 can be designed in various shapes (e.g., circular, square, rectangular, etc.) and sizes to accommodate different insertion protrusions 220. The insertion protrusion 220 is a protrusion provided on the circuit board for insertion into the insertion hole 210. Both the insertion hole 210 and the insertion protrusion 220 can be provided in multiple numbers.

[0129] Please refer to Figure 10 In one example, the first circuit board 21 is provided with a plug hole 210, and the second circuit board 22 is provided with a plug protrusion 220. In another example, the first circuit board 21 is provided with a plug protrusion 220, and the second circuit board 22 is provided with a plug hole 210. The plug protrusion 220 is fixed in the plug hole 210 by soldering. The first circuit board 21 is also provided with a female connector 21a, and the second circuit board 22 is also provided with a pin header 22a. The electrical connection between the first circuit board 21 and the second circuit board 22 is achieved by inserting the pin header 22a into the female connector 21a. During installation, the connection is completed by simply inserting the pin header 22a into the slot of the female connector 21a, without the need for additional tools or equipment, which is convenient and quick.

[0130] Please refer to Figure 11 In some embodiments, the second housing 12 is provided with an inserting slot 120 , and the second circuit board 22 is inserted into the inserting slot 120 away from an edge of the first circuit board 21 .

[0131] In this way, the plug-in method simplifies the installation and removal process of the second circuit board 22, stabilizes the position of the second circuit board 22, and does not require additional fixing tools or complicated connection steps, thereby significantly improving assembly efficiency.

[0132] Specifically, the insertion slot 120 is a groove provided on the second housing 12 for accommodating the edge of the second circuit board 22. The width of the insertion slot 120 can be slightly larger than the width of the edge of the second circuit board 22 to facilitate insertion of the second circuit board 22. The length of the insertion slot 120 can be longer than the length of the second circuit board 22 to reserve a certain amount of space to compensate for processing errors of the second circuit board 22.

[0133] The plugging slot 120 can be formed on the inner surface of the second housing 12 or formed in other ways. For example, two columns are provided on the inner surface of the second housing 12, and the plugging slots 120 are aligned with each other.

[0134] Please refer to Figure 10aIn some embodiments, the first circuit board 21 includes functional circuitry 214, which includes a battery management circuit 2140, an inverter circuit 2141, and a solar charging circuit 2142. The battery management circuit 2140 is electrically connected to the battery module 30 to connect or disconnect the battery module 30 from external circuits. The inverter circuit 2141 is electrically connected to the battery module 30 through the battery management circuit 2140 to convert AC power into DC power. The solar charging circuit 2142 is electrically connected to the battery module 30 through the battery management circuit 2140 to maximize the power generated by the solar panel. In this way, the battery management circuit 2140, inverter circuit 2141, and solar charging circuit 2142 are integrated on the first circuit board 21, achieving a multifunctional all-in-one design. This integrated design reduces the number of components, simplifies circuit layout, improves the compactness and reliability of the device, and enhances assembly efficiency.

[0135] The battery management circuit 2140 monitors the status of the battery module 30 in real time, including parameters such as voltage, current, and temperature, ensuring that the battery operates within a safe range. This helps extend the battery life and improve its reliability and safety. The solar charging circuit 2142 is designed to maximize the power generated by the solar panels. By optimizing the charging process, it improves the efficiency of solar energy utilization, making the energy storage power supply 100 more efficient in solar-powered scenarios.

[0136] Specifically, the battery management circuit 2140 is a circuit for monitoring and managing the battery module 30. The battery management circuit 2140 can monitor the voltage, current, and temperature of the battery module 30 to ensure that the battery module 30 operates within a safe range. It can also control the charge and discharge process of the battery module 30 to extend the life of the battery module 30. The battery management circuit 2140 may include functions such as overcharge protection, over-discharge protection, and short-circuit protection.

[0137] The solar charging circuit 2142 is a circuit for converting the electrical energy generated by the solar panel into electrical energy suitable for storage in the battery module 30. The solar charging circuit 2142 can be connected to the solar panel, which is used to convert solar energy into electrical energy. The solar charging panel is used to convert the electrical energy of the solar panel into electrical energy that can be stored in the energy storage power supply 100.

[0138] In some embodiments, the second circuit board 22 includes an output circuit, a display screen, and buttons, etc. The output circuit is used to electrically connect to an external circuit and output power. The display screen is used to display information such as the input power and output power, and power of the energy storage power supply 100. The buttons can be used to control the working status of the energy storage power supply 100.

[0139] In this way, the output circuit allows the energy storage power supply 100 to be directly connected to an external circuit. Users can conveniently use the energy storage power supply 100 to power various devices without the need for additional adapter equipment or complicated connection steps, thereby improving convenience of use.

[0140] Specifically, the output circuit refers to a circuit for transmitting electrical energy from the energy storage power supply 100 to an external device. The output circuit can include multiple interfaces, such as a USB interface, a DC output interface, an AC output interface, etc., to meet the needs of different devices.

[0141] External circuit electrical connection refers to the electrical connection between the energy storage power supply 100 and an external device. The external circuit electrical connection can be wired or wireless, and wired connections include USB cables, power adapter cables, etc.

[0142] The output power of the output circuit can be adjusted according to specific needs, for example, to support 5V / 2A USB output, or 12V / 10A DC output, etc. It should be noted that the values ​​here are only examples for ease of understanding and cannot be used as limitations on the embodiments of the present invention.

[0143] Please refer to Figure 10a In some embodiments, the second circuit board 22 includes a DC conversion circuit 22b, which is electrically connected to the battery module 30 through the battery management circuit 2140, and outputs the electrical energy of the battery module 30 through the output port 102a after DC conversion.

[0144] In this way, the electric energy after DC conversion can be used to power various DC devices, such as mobile devices, lighting equipment, etc., through the output port 102a, thereby enhancing the versatility and practicality of the energy storage power supply 100 and making it suitable for a variety of application scenarios.

[0145] Please refer to Figure 1 In some embodiments, the output circuit includes at least one of a USB port 101 and a vehicle charging port 102. In one embodiment, the USB port 101 is exposed through a panel 112. In one embodiment, the vehicle charging port 102 is exposed through a panel 112. In one embodiment, the USB port 101 and the vehicle charging port 102 are exposed through a panel 112.

[0146] In this way, by integrating the USB port 101 and the vehicle charging port 102 , the dependence on external adapters or connectors is reduced, thereby reducing the user's usage cost.

[0147] Specifically, USB port 101 is a universal serial bus interface used to connect various USB devices. USB port 101 can provide a standardized interface, making it convenient for users to connect and charge various USB devices, such as mobile phones, tablets, and laptops. USB port 101 can support multiple standards, such as USB-A, USB-C, and USB-B. Common output power includes 5V / 2A, 9V / 2A, and 12V / 1.5A. USB port 101 can be designed to support fast charging protocols such as QC3.0 and PD.

[0148] The vehicle charging port 102 is a charging interface designed specifically for in-vehicle devices. It provides a charging interface for in-vehicle devices, allowing users to conveniently charge their devices while in the vehicle. The vehicle charging port 102 supports outputs such as 12V and 24V, and can be designed to support a variety of in-vehicle devices, such as mobile phones, tablets, and in-vehicle navigation systems.

[0149] Please refer to Figure 3 and Figure 12 In some embodiments, the battery module 30 includes a bracket 31 and a plurality of battery cells 32 mounted on the bracket 31 at one end. The second shell 12 is formed with a plurality of mounting grooves 121. The other end of the battery cell 32 is embedded in the mounting groove 121. The bracket 31 is fixedly mounted on the second shell 12 to fix the plurality of battery cells 32 to the second shell 12.

[0150] In this way, the design of the bracket 31 allows one end of multiple battery cells 32 to be pre-installed on the bracket 31 during the assembly process, and then the entire battery module 30 is embedded in the mounting groove 121 to fix the entire battery module 30 on the second shell 12, simplifying the assembly steps and improving assembly efficiency.

[0151] Mounting slot 121 simplifies the installation process of battery cell 32. Simply inserting one end of the battery cell 32 into the mounting slot 121 completes the fixation, eliminating the need for additional fixing tools or complex connection steps, significantly improving assembly efficiency. Furthermore, the design of mounting slot 121 allows one end of the battery cell 32 to be securely embedded in the second housing 12, preventing the battery cell 32 from shifting or loosening due to vibration or impact, thereby improving the installation stability of the battery module 30.

[0152] Specifically, the bracket 31 is a structural component used to fix and support the battery cell 32. The bracket 31 can provide stable mechanical support to ensure that the battery cell 32 does not move or loosen during operation;

[0153] The bracket 31 can be fixedly mounted on the second housing 12 by bolt connection, snap connection, plug connection, etc. The bracket 31 and the second housing 12 can also be an integrally formed structure, which can reduce the connection gap and weak points when the bracket 31 and the second housing 12 are connected, thereby enhancing the overall rigidity of the bracket 31 and the second housing 12.

[0154] The plurality of mounting grooves 121 may correspond one-to-one with the plurality of battery cells 32. The mounting grooves 121 may be formed by the inner wall of the second housing 12 and a rib structure provided on the inner wall of the second housing 12. The mounting grooves 121 are used to secure the battery cells 32. The groove wall of the mounting groove 121 may be larger than the diameter of the battery cell 32. The shape of the inner wall of the mounting groove 121 may be similar to the shape of the outer surface of the battery cell 32. The number of mounting grooves 121 may be two, three, four, or even more.

[0155] Please refer to Figure 12 In some embodiments, the second housing 12 includes a second substrate 122 and a second side plate 123 connected to the second substrate 122 . The second side plate 123 is formed with a mounting groove 121 . The second side plate 123 is connected to the first housing 11 .

[0156] In this way, the mounting grooves 121 on the second side plate 123 can optimize the layout of the battery cells 32 , making the connection between the battery cells 32 and the housing more compact, reducing unnecessary space occupation, and improving space utilization.

[0157] Furthermore, by designing the second housing 12 as a combination of the second base plate 122 and the second side plate 123, a step-by-step installation of the battery cells 32 can be achieved. This step-by-step installation method allows different component parts to be handled separately during the assembly process, thereby simplifying the assembly steps and improving assembly efficiency.

[0158] Specifically, the second substrate 122 is a part of the second housing 12 and is generally a flat plate-shaped structure. The shape of the second substrate 122 can be a regular shape such as a rectangle or a circle, or an irregular shape. For example, the shape of the second substrate 122 is a rectangle.

[0159] The second side plate 123 is another part of the second housing 12 and can be a plate-shaped structure perpendicular to the second base plate 122. It is used to connect to the first housing 11 and form a part of the accommodating chamber 13. The second side plate 123 can be connected to the first housing 11 by bolt connection, snap connection, plug connection, etc.

[0160] Please refer to Figure 12In some embodiments, the second substrate 122 is provided with a supporting rib 1221 , and the supporting rib 1221 is formed with a first limiting groove 1222 , and the battery cell 32 rests on the groove wall of the first limiting groove 1222 .

[0161] In this way, the supporting ribs 1221 can not only provide a heat dissipation function, but also provide pre-positioning for the battery cells 32 , thereby facilitating the installation of the battery cells 32 .

[0162] Specifically, the number of support ribs 1221 can be one or more. For example, the number of support ribs 1221 can be two, and the two support ribs 1221 are arranged in parallel on the surface of the second substrate 122 facing the battery cell 32. The two support ribs 1221 are each formed with a plurality of first limiting grooves 1222, each of which is used to limit the position of a corresponding battery cell 32. In this way, the battery cell 32 can be stably fixed in the first limiting groove 1222, thereby preventing the battery cell 32 from shaking during use.

[0163] The shape of the first limiting groove 1222 may match the shape of the outer circumference of the battery cell 32. For example, the battery cell 32 may be cylindrical, and the shape of the first limiting groove 1222 may be an arc.

[0164] Please refer to Figure 12 、 Figure 12a 、 Figure 13 and Figure 14 In some embodiments, the battery cell 32 includes a first end 320 and a second end 321 along its length direction. The second end 321 of the battery cell 32 is formed with a pressure relief structure 32a. The second end 321 of the battery cell 32 is embedded in the mounting groove 121. A support structure 121a is provided in the mounting groove 121. The support structure 121a abuts against the second end 321 of the battery cell 32, so that a certain distance is generated between the second end 321 and the bottom of the mounting groove 121 to form a pressure relief groove 121b. The pressure relief groove 121b is connected to the accommodating chamber 13.

[0165] In this way, when a battery cell 32 experiences thermal runaway, the generated high-pressure gas can be promptly discharged through the pressure relief groove 121b, preventing gas accumulation within the battery module 30 and causing an explosion, significantly improving the safety performance of the energy storage power supply 100 in the event of thermal runaway. Furthermore, the pressure relief groove 121b can connect to the pressure relief structures 32a of multiple battery cells 32, allowing the pressure relief structure 32a of any battery cell 32 in the battery module 30 to achieve the purpose of runaway pressure relief.

[0166] Specifically, the pressure relief structure 32a can be an explosion-proof valve or a notch provided at the second end 321 of the battery cell 32. For example, the pressure relief structure 32a can be an explosion-proof valve with a weak point or device provided inside. When the pressure in the battery cell 32 increases, the weak point is dislodged by the pressure, thereby releasing the high-pressure gas in the battery cell 32, thereby preventing the battery cell 32 from exploding or catching fire due to abnormal conditions such as overcharging, over-discharging, and short circuiting. For another example, the pressure relief structure 32a can be a notch formed by mechanical processing at the second end 321 of the battery cell 32, with the notch forming the aforementioned weak point.

[0167] The support structure 121a may be a protrusion protruding from the inner wall of the accommodating chamber 13. For example, the support structure 121a may be a rib protruding from the inner wall of the accommodating chamber 13, so that the support structure 121a can be used to support the battery cell 32 and can space one end of the battery cell 32 from the inner wall of the accommodating chamber 13, thereby forming a pressure relief groove 121b between the battery cell 32 and the inner wall of the accommodating chamber 13.

[0168] Please refer to Figure 12 In some embodiments, a notch 121 c is provided on the side wall of the mounting groove 121 , and the pressure relief groove 121 b is connected to the accommodating chamber 13 through the notch 121 c .

[0169] Thus, by providing a notch 121c on the sidewall of the mounting groove 121 to connect the pressure relief groove 121b with the accommodating chamber 13, this design is relatively simple and easy to implement during production. Compared to complex internal air guide channels or other pressure relief structures 32a, the notch 121c is easier to manufacture, reducing manufacturing complexity, lowering production costs, and improving production efficiency. Furthermore, the size, shape, and position of the notch 121c can be adjusted to optimize pressure relief and heat dissipation performance to suit different working environments and safety standards.

[0170] Specifically, the number of the notches 121c can be one or more. For example, the number of the notches 121c can be two, three, four or even more. Multiple notches 121c can be symmetrically opened on the sidewalls of the mounting groove 121, which can enhance the pressure relief effect.

[0171] Please refer to Figure 12 In some embodiments, a plurality of mounting grooves 121 are arranged in parallel, and two adjacent mounting grooves 121 are connected through a notch 121 c, wherein the notch 121 c on the side wall of one mounting groove 121 is connected to the accommodating chamber 13 .

[0172] Thus, by forming a notch 121 c on the side wall of the mounting groove 121 , the pressure relief groove 121 b is connected to the accommodating chamber 13 , thereby guiding the high-pressure gas ejected from the battery cell 32 out of the pressure relief groove 121 b to achieve the purpose of pressure relief.

[0173] Furthermore, by arranging multiple mounting grooves 121 in parallel, connecting two adjacent mounting grooves 121 through notches 121c, and connecting the notch 121c on the side wall of one of the mounting grooves 121 to the accommodating chamber 13, this design forms a continuous pressure relief channel. When any battery cell 32 experiences thermal runaway, the generated high-pressure gas can not only be discharged into the accommodating chamber 13 through the notch 121c of its own pressure relief groove 121b, but can also be diffused and discharged throughout the entire pressure relief channel through the notches 121c of adjacent mounting grooves 121.

[0174] Specifically, the size of the notch 121c connecting two adjacent mounting grooves 121 and the notch 121c connecting the accommodating chamber 13 can be the same or different. The notch 121c can be formed by machining or injection molding. The shape of the notch 121c can be arbitrarily set according to needs and is not limited in the embodiments of the present invention.

[0175] Please refer to Figure 12 and Figure 14 In some embodiments, a gap is formed between the sidewall of the mounting groove 121 and the sidewall of the battery cell 32 , and the pressure relief groove 121 b is connected to the accommodating chamber 13 through the gap.

[0176] In this way, a gap is formed between the sidewall of the mounting groove 121 and the sidewall of the battery cell 32 , so that the high-pressure gas ejected from the battery cell 32 can flow into the accommodating chamber 13 through the gap to achieve the purpose of pressure relief.

[0177] In addition, by utilizing the gap between the side wall of the installation groove 121 and the side wall of the battery cell 32 to achieve communication between the pressure relief groove 121b and the accommodating chamber 13, this design does not require additional processing of complex pressure relief channels or connecting structures, reduces the complexity of the manufacturing process, reduces production costs, and improves production efficiency.

[0178] Specifically, the diameter of the battery cell 32 can be adapted to the diameter of the mounting groove 121, so that a gap is formed between the side wall of the mounting groove 121 and the side wall of the battery cell 32, and the pressure relief groove 121b is connected to the accommodating chamber 13 through the gap, so that the high-pressure gas released by the battery cell 32 into the pressure relief groove 121b can flow from the gap into the accommodating chamber 13.

[0179] Please refer to Figure 12In some embodiments, the support structure 121 a is arc-shaped, the battery cell 32 is a cylindrical battery, and the support structure 121 a abuts against the edge of the second end 321 of the battery cell 32 .

[0180] In this way, the support structure 121 a matches the shape of the battery cell 32 , which enables the support structure 121 a to effectively support the battery cell 32 and prevent the battery cell 32 from shaking.

[0181] Please refer to Figure 12 In some embodiments, the support structure 121 a is a rib disposed in the mounting groove 121 , and the rib is connected to the side wall of the mounting groove 121 .

[0182] Thus, the ribs ensure that the second end 321 of the battery cell 32 is spaced a certain distance from the bottom of the mounting groove 121, thereby ensuring the formation of the pressure relief groove 121b and its communication with the accommodating chamber 13. Furthermore, the ribs effectively disperse the pressure on the second end 321 of the battery cell 32, preventing the battery cell 32 from shaking or shifting within the mounting groove 121, thereby improving the overall structural stability of the battery module 30.

[0183] Specifically, the ribs can have various forms, such as straight ribs and arc-shaped ribs. For example, the ribs can be arc-shaped, and the arc-shaped ribs can be aligned with the sidewalls of the battery cells 32 and positioned adjacent to the mounting slots 121. Because the ribs directly abut the second ends 321 of the battery cells 32, if the second ends 321 are subjected to significant pressure and collapse, this could cause the battery cells 32 to short-circuit. However, the arc-shaped ribs, positioned adjacent to the mounting slots 121 and abutting the edges of the second ends 321 of the battery cells 32, transfer more pressure to the sidewalls of the battery cells 32 rather than to the ends, significantly reducing the risk of short-circuiting the battery cells 32.

[0184] The ribs can be integrally formed with the sidewalls of the mounting groove 121, which can reduce connection gaps and weak points, thereby improving the structural rigidity of the ribs and thus improving the supporting performance of the ribs. The ribs can be a continuous structure, which can be easily manufactured and reduce manufacturing costs.

[0185] Please refer to Figure 12 and Figure 14 In some embodiments, there are two convex ribs, which are arranged opposite to each other and form a pressure relief groove 121b.

[0186] Thus, the two ribs are arranged opposite each other to form the pressure relief groove 121b. This design effectively supports and relieves pressure on the battery cells 32 without adding additional space. The two ribs evenly distribute the pressure on the second ends 321 of the battery cells 32, preventing the battery cells 32 from tilting or shaking within the mounting groove 121. This further improves the overall structural stability of the battery module 30, and particularly protects the battery cells 32 when the energy storage power supply 100 is subjected to vibration or is dropped, reducing the risk of damage to the battery cells 32.

[0187] Specifically, the two ribs may have a symmetrical structure, which can provide more uniform support for the battery cell 32 .

[0188] Please refer to Figure 12 and Figure 14 In some embodiments, the battery cell 32 is a cylindrical battery, and the rib includes a supporting portion 121e and a connecting portion 121f. The supporting portion 121e is arranged in the mounting groove 121 in an arc shape. The connecting portion 121f passes through the two mounting grooves 121 and is connected to the two supporting portions 121e at both ends. The two ribs pass through multiple mounting grooves 121 and form a guide channel 121d. The guide channel 121d is connected to the accommodating chamber 13, and the pressure relief structure 32a faces the guide channel 121d.

[0189] In this way, when any battery cell 32 experiences thermal runaway, the guide channel 121d can guide the high-pressure gas and quickly discharge the high-pressure gas, reducing the accumulation and spread of high-pressure gas in the battery module 30. This design helps to suppress the spread of thermal runaway among multiple battery cells 32, protect other battery cells 32 from the effects of thermal runaway, and further improve the safety of the energy storage power supply 100. The arc-shaped support portion 121e can stably support the cylindrical battery and prevent the cylindrical battery from shaking. The connecting portion 121f passes through the two mounting grooves 121 and is connected to the two support portions 121e at both ends. This design not only enhances the stability of the battery cell 32 in a single mounting groove 121, but also connects the adjacent support portions 121e together through the connecting portion 121f, thereby improving the structural stability of the entire battery module 30.

[0190] Specifically, the inner wall surfaces of the two ribs can form a guide channel 121d. The guide channel 121d can be formed with an open port. The open port can be connected to the accommodating chamber 13. The bottom wall of the second end 321 of the battery cell 32 can be located within the guide channel 121d. The pressure relief structure 32a can be provided on the bottom wall of the second end 321 of the battery cell 32. When thermal runaway occurs in the battery cell 32, the high-pressure gas released by the pressure relief structure 32a can enter the guide channel 121d and be discharged to the accommodating chamber 13 under the guidance of the guide channel 121d.

[0191] The connecting portion 121f and the supporting portion 121e may be an integrally formed structure, which can reduce connection gaps and weak points, thereby enhancing the overall structural rigidity of the connecting portion 121f and the supporting portion 121e.

[0192] Please refer to Figure 8 、 Figure 12 and Figure 16 In some embodiments, the first substrate 111 and the second substrate 122 are disposed opposite to each other, and the panel 112 and the second side panel 123 are disposed opposite to each other.

[0193] As such, the layout of the first substrate 111 , the second substrate 122 , the panel 112 and the second side panel 123 facilitates the installation of the first housing 11 and the second housing 12 , thereby improving assembly efficiency.

[0194] Please refer to Figure 13 、 Figure 14 、 Figure 15 and Figure 15a In some embodiments, the first end 320 is provided with a first electrode 3200 and a second electrode 3201, and the battery module 30 includes an electrical connector 33, which connects two adjacent battery cells 32 by connecting the first electrode 3200 of the battery cell 32 and the second electrode 3201 of the adjacent battery cell 32, and the second end 321 is embedded in the mounting groove 121.

[0195] In this way, through the cooperation of the first electrode 3200, the second electrode 3201, and the electrical connector 33, multiple battery cells 32 can be quickly electrically connected and assembled as a whole, simplifying the assembly process and improving assembly efficiency. The second end 321 of the battery cell 32 is embedded in the mounting groove 121. Combined with the fixation of the first electrode 3200, the second electrode 3201, and the electrical connector 33, this ensures the stability of the battery cell 32 in vibration or impact environments and reduces the risk of displacement or loosening.

[0196] Specifically, a battery cell 32 is the basic unit of the battery module 30, responsible for storing and providing electrical energy. Multiple battery cells 32 can be combined in series or parallel to form a battery module 30, providing the required voltage and capacity. Battery cells 32 can be of various types, such as lithium-ion batteries, lead-acid batteries, or nickel-metal hydride batteries. Battery cells 32 can be designed in various shapes and sizes, such as cylindrical, square, or pouch.

[0197] The first electrode 3200 can be a positive electrode. The second electrode 3201 can be a negative electrode. Taking a lithium-ion battery as an example, the positive electrode can include a positive electrode current collector and a positive electrode active material layer. The positive electrode current collector can be made of aluminum, and the positive electrode active material layer can include positive electrode active materials such as lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode sheet can include a negative electrode current collector and a negative electrode active material layer. The negative electrode current collector can be made of copper, and the negative electrode active material layer can include negative electrode active materials such as carbon or silicon.

[0198] The electrical connector 33 is used to connect adjacent battery cells 32. By interfacing with the electrodes of different battery cells 32, the electrical connector 33 establishes an electrical connection between adjacent battery cells 32, ensuring stable current transmission. The electrical connector 33 can take various forms, such as connecting pieces, connecting wires, and welding points. The material of the electrical connector 33 can be a highly conductive metal, such as copper or aluminum. The electrical connector 33 can also be designed to provide protective features, such as an insulation layer or anti-loosening structure.

[0199] Please refer to Figure 17 、 Figure 18 、 Figure 19 and Figure 19a In some embodiments, the battery module 30 and the circuit board module 20 are spaced apart along the first direction v of the accommodating chamber 13. The battery module 30 forms a first high area 34 and a first low area 35 with a height difference in the first direction v. The circuit board module 20 forms a second high area 23 and a second low area 24 with a height difference in the first direction v. The first high area 34 and the second low area 24, as well as the first low area 35 and the second high area 23, partially overlap in the first direction v. The first high area 34 and the second high area 23 partially overlap in the second direction h. The second direction h is perpendicular to the first direction v.

[0200] In this way, the first low area 35 of the battery module 30 can provide an avoidance space for the second high area 23 of the circuit board module 20, and the second low area 24 of the circuit board module 20 can provide an avoidance space for the first high area 34 of the battery module 30. By setting a height difference in the first direction v, the battery module 30 and the circuit board module 20 partially overlap in the second direction h. This staggered layout makes the battery module 30 compact, significantly improves the space utilization of the accommodating chamber 13, reduces the overall volume, and improves the portability of the energy storage power supply 100.

[0201] Specifically, for a rectangular parallelepiped energy storage power supply 100 , the first direction v may be the height direction of the energy storage power supply 100 , and the second direction h may be the length direction of the energy storage power supply 100 .

[0202] The height difference refers to different height areas of the battery module 30 or the circuit board module 20 in the first direction v. The overlap refers to that the projection areas of the battery module 30 and the circuit board module 20 in the first direction v or the second direction h overlap each other.

[0203] Please refer to Figure 17 and Figure 18 In some embodiments, the first circuit board 21 forms a second high area 23 and a second low area 24 .

[0204] Thus, by dividing the circuit board module 20 into the first circuit board 21 and the second circuit board 22, and forming the second high area 23 and the second low area 24 on the first circuit board 21, the space of the accommodating chamber 13 can be more flexibly utilized. The height difference design of the first circuit board 21 provides more space for the second circuit board 22 or other components to avoid, thereby further optimizing the overall layout and improving space utilization.

[0205] Please refer to Figure 16 and Figure 18 In some embodiments, the first shell 11 and the second shell 12 are arranged along the height direction, the first shell 11 is arranged on the top of the second shell 12, the circuit board module 20 includes a board body 211 and a functional element 20b arranged on the board body 211, the board body 211 is arranged on the top of the first shell 11, and the functional element 20b is arranged from the board body 211 toward the battery module 30.

[0206] Thus, this layout can shorten the electrical connection distance between the functional element 20b on the circuit board module 20 and the battery module 30, reduce the length and complexity of the connection line, and reduce signal transmission loss and electromagnetic interference.

[0207] Specifically, the functional element 20b may include a sensor, a controller, a communication module, etc. The functional element 20b may implement various functions of the circuit board module 20, such as monitoring battery status, controlling charging and discharging processes, etc. The functional element 20b may include a variety of electrical components with different heights and functions. For example, the functional element 20b may include a first heating element 230 and a second heating element 240.

[0208] Please refer to Figure 16 and Figure 18 In certain embodiments, the board 211 is fixed to the housing 10, and the functional elements 20b are arranged along the first direction v toward the battery module 30, so that the circuit board module 20 forms a second high area 23 and a second low area 24. By optimizing the layout of the functional elements 20b, the circuit board module 20 can form the second high area 23 and the second low area 24, thereby forming a staggered arrangement with the first high area 34 and the first low area 35 of the battery module 30, thereby improving the space utilization of the accommodating chamber 13.

[0209] Please refer to Figure 18 In some embodiments, the second high zone 23 has a first heating element 230 , and the second low zone 24 has a second heating element 240 . The heat generated by the first heating element 230 is greater than the heat generated by the second heating element 240 .

[0210] Thus, the first heating element 230, which generates a large amount of heat, is arranged in the second high zone 23. This allows the relatively open space in the second high zone 23 to be utilized or an additional heat dissipation structure to be designed to improve heat dissipation efficiency. The second heating element 240, which generates a smaller amount of heat, is arranged in the second low zone 24. Even though the space in the second low zone 24 is relatively compact, poor heat dissipation will not affect performance.

[0211] Specifically, the first heating element 230 can be a component on the circuit board that generates a large amount of heat, such as a MOS tube, an inductor, a transformer, a heat sink, etc. The second heating element 240 can be a component on the circuit board that generates a small amount of heat, such as a connector, a capacitor, etc.

[0212] In other embodiments, components with higher heights are placed in the second higher region 23 , and components with lower heights are placed in the second lower region 24 .

[0213] Please refer to Figure 16 、 Figure 17 and 18 In some embodiments, the first circuit board 21 includes a board body 211 and a cooling fan 212 disposed on the board body 211. The cooling fan 212 is formed at one end of the second high area 23 away from the second low area 24 and forms at least a portion of the second high area 23. The cooling fan 212 forms an airflow that flows through the second low area 24 to dissipate heat.

[0214] Thus, the position of the cooling fan 212 allows it to dissipate heat from both the second high zone 23 and the second low zone 24 simultaneously, with the cooling effect being better on the second high zone 23, effectively reducing the temperature of the first heating element 230, which generates a relatively large amount of heat. This active heat dissipation design can significantly improve the heat dissipation efficiency of the energy storage power supply 100, especially under high-load operating conditions, ensuring that the first heating element 230 operates within a safe temperature range.

[0215] In addition, the heat dissipation fan 212 forms at least a portion of the second high area 23 , which allows the heat dissipation fan 212 to be a fan with greater wind power, thereby providing a better heat dissipation effect.

[0216] Specifically, the cooling fan 212 is an active heat dissipation device that generates airflow through rotation to remove heat. The cooling fan 212 can be mounted on the plate 211 via bolts or other mechanical connections. The cooling fan 212 can either draw in or exhaust air. When the cooling fan 212 is configured to blow air, it can generate a cooling airflow toward the second low zone 24. When the cooling fan 212 is configured to exhaust air, it can generate a cooling airflow toward the second high zone 23.

[0217] Please refer to Figure 16 、 Figure 17 and 18 In some embodiments, the first circuit board 21 further includes a duct element 213 disposed on the board body 211 , the duct element 213 forming an air flow channel from the cooling fan 212 to the second high area 23 , and the duct element 213 forming part of the second low area 24 .

[0218] Thus, the airflow channel formed by the air duct element 213 can guide the airflow generated by the cooling fan 212 more directly to the heating element in the second high zone 23, thereby improving heat dissipation efficiency. This directional heat dissipation design ensures that the first heating element 230 located in the second high zone 23 is cooled more effectively, especially under high-load working conditions.

[0219] Specifically, the duct element 213 is a structural component for guiding airflow. The inlet of the duct element 213 is located near the second high zone 23, and the outlet of the duct element 213 is located near the air inlet 1100 of the cooling fan 212. Under the suction force of the cooling fan 212, the airflow enters the duct element 213 through the second low zone 24, flows through the second high zone 23, and is then discharged through the cooling fan 212. The heat generation in the second low zone 24 is relatively low, so the airflow is not overheated after passing through the second low zone 24. When the airflow reaches the second high zone 23, the relatively low temperature of the airflow is more conducive to removing heat from the second high zone 23. The duct element 213 can be made of plastic or metal. The duct element 213 can be an air duct, an air duct, or other similar structure. For example, the duct element 213 can be a plastic air duct, with the inlet of the air duct located near the air outlet 1101 of the cooling fan 212 and the outlet of the air duct located near the second high zone 23.

[0220] Please refer to Figure 17 and Figure 19 In some embodiments, the bracket 31 is fixedly mounted on the housing 10 , and some battery cells 32 are stacked along the first direction v so that the battery module 30 forms a first high area 34 and a first low area 35 .

[0221] In this way, by stacking some battery cells 32 along the first direction v, a first high area 34 and a first low area 35 with a height difference can be formed, thereby providing space for the circuit board module 20 or other components to avoid. This design significantly improves the space utilization of the storage chamber 13, making the overall structure of the energy storage power supply 100 more compact.

[0222] Specifically, the bracket 31 can be fixedly mounted on the housing 10 by bolt connection, snap connection, plug connection, etc. Two layers of battery cells 32 can be stacked in the first high area 34, and one layer of battery cells 32 can be stacked in the first low area 35. This allows the battery cells 32 in different areas of the battery module 30 to have height differences, thereby forming the first high area 34 and the first low area 35.

[0223] Please refer to Figure 17 、 Figure 19 and Figure 20 In some embodiments, the energy storage power supply 100 includes a heat insulating member 40 disposed between the battery module 30 and the circuit board module 20 , and the heat insulating member 40 covers the battery module 30 .

[0224] In this way, the thermal insulation 40 effectively isolates the heat transfer between the battery module 30 and the circuit board module 20, preventing the heat generated by the battery module 30 from affecting the normal operation of the circuit board module 20, improving the thermal stability of the circuit board module 20, and avoiding the performance degradation or shortening of the life of the circuit board module 20 due to overheating.

[0225] Specifically, the heat insulating member 40 is a component for reducing heat transfer and can be made of a low thermal conductivity material, such as ceramic fiber, asbestos or aerogel, etc. The heat insulating member 40 can be designed in a plate shape, a sheet shape or other suitable shapes.

[0226] Covering the battery module 30 means that the thermal insulation member 40 completely covers the battery module 30 , or in other words, the orthographic projection of the battery module 30 on the thermal insulation member 40 is located inside the thermal insulation member 40 .

[0227] Please refer to Figure 16 and Figure 20 In some embodiments, a shielding member 25 is provided on the side of the circuit board module 20 facing away from the battery module 30. In one embodiment, the shielding member 25 is used for heat dissipation. In one embodiment, the shielding member 25 is used for electromagnetic interference shielding. In one embodiment, the shielding member 25 is used for both heat dissipation and electromagnetic interference shielding.

[0228] Thus, shielding member 25, positioned on the side of circuit board module 20 facing away from battery module 30, effectively directs and dissipates heat generated by circuit board module 20, preventing heat accumulation and improving heat dissipation efficiency. By dissipating heat promptly, the risk of circuit board module 20 failure due to overheating is reduced, improving the reliability of circuit board module 20 during prolonged operation or under high load conditions. Furthermore, by reducing electromagnetic interference, shielding member 25 helps improve the signal integrity and reliability of circuit board module 20, ensuring accurate and stable data transmission.

[0229] Specifically, shielding member 25 is a component used to dissipate heat and can be made of a highly thermally conductive material, such as aluminum, copper, or graphite. Shielding member 25 can take a variety of forms, including heat sinks, heat pipes, fans, and thermal paste. Shielding member 25 can dissipate heat passively or actively. Shielding member 25 can achieve heat dissipation through various methods, such as increasing its surface area, using thermally conductive materials, and designing air flow channels.

[0230] Shielding member 25 can be made of electromagnetic shielding material (such as a metal plate or conductive coating). This effectively shields the electromagnetic interference generated by circuit board module 20, preventing it from affecting other surrounding electronic devices. It also prevents external electromagnetic interference from entering circuit board module 20, ensuring its normal operation. If both heat dissipation and electromagnetic interference shielding are required, shielding member 25 can be made of aluminum, copper, or other materials.

[0231] In some embodiments, the shielding member 25 abuts against the housing 10 .

[0232] In this way, the shielding member 25 abuts against the housing 10, allowing the heat generated by the circuit board module 20 to be directly transferred to the housing 10, and then dissipated to the external environment through the housing 10. This design significantly improves heat dissipation efficiency, especially under high-load working conditions, ensuring stable operation of the circuit board module 20.

[0233] Please refer to Figure 21 、 Figure 22 、 Figure 23 and Figure 24 In some embodiments, the energy storage power supply 100 further includes a support mesh 50. The housing 10 is provided with a ventilation portion 110a having vents 110 formed therein. The battery module 30 is disposed within the housing 10. The support mesh 50 is disposed on the inner side of the housing 10 and attached to the ventilation portion 110a to support the ventilation portion 110a.

[0234] In this way, by providing a support net 50 on the inner side of the housing 10 and attaching it to the ventilation portion 110a to support the ventilation portion 110a, the structural strength of the ventilation portion 110a can be significantly enhanced. The support net 50 not only prevents foreign matter from entering the interior of the housing 10 through the vent 110, but also reduces the risk of rupture of the ventilation portion 110a during drops or vibrations, thereby improving the safety of the ventilation portion 110a. In addition, the design of the support net 50 does not affect the heat dissipation function of the vent 110, ensuring that the battery module 30 and other electrical components can effectively dissipate heat during normal operation, further improving the reliability and service life of the energy storage power supply 100.

[0235] Specifically, the support net 50 can be a protective structure disposed on the inner side of the housing 10 to cover the vent 110. The support net 50 can be made of a wire mesh, a plastic mesh, or other material with sufficient strength and air permeability. The support net 50 can be directly attached to the inner side of the housing 10 by bonding or welding, or it can be attached to the inner side of the housing 10 by other mounting structures. For example, the support net 50 can be attached to the vent portion 110a using a sealant.

[0236] The number of support nets 50 may correspond to the number of vents 110. For example, if there is one vent 110, one support net 50 is provided. If there are multiple vents 110, multiple support nets 50 are provided.

[0237] Please refer to Figure 24 In some embodiments, the first shell 11 is formed with a vent 110 , and the support net 50 is disposed on the inner side of the first shell 11 .

[0238] Thus, if the vent 110 area or the support net 50 of the housing 10 is damaged, the first housing 11 and the second housing 12 are detachably connected, so the user can replace the damaged first housing 11 or second housing 12 separately without having to replace the entire housing 10. This modular design not only reduces maintenance costs but also extends the service life of the energy storage power supply 100.

[0239] Please refer to Figure 23 and Figure 24 In some embodiments, a limiting strip 113 is provided on the inner side of the first shell 11 , and the limiting strip 113 and the inner side of the first shell 11 jointly define a second limiting groove 114 , and the support net 50 is at least partially disposed in the second limiting groove 114 .

[0240] In this way, the second limiting groove 114 secures the support net 50, effectively preventing the support net 50 from shifting or shaking within the housing 10. This ensures that the support net 50 always covers the vent 110, maintaining the protective function of the support net 50, especially when the energy storage power supply 100 is dropped, vibrated, or impacted. In addition, the limiting strip 113 can also serve as a guide structure during the installation of the support net 50, thereby facilitating the rapid installation of the support net 50.

[0241] Specifically, the limiting strip 113 can be a protrusion extending away from the inner side surface of the first housing 11. The number of limiting strips 113 can be multiple, such as two, three, four, or even more. The limiting strip 113 and the first housing 11 can be integrally formed, which can reduce connection gaps and weak points, thereby enhancing the structural rigidity of the limiting strip 113. The limiting strip 113 and the first housing 11 can also be separately formed, which can facilitate replacement of the limiting strip 113 and thus increase the service life of the limiting strip 113.

[0242] Please refer to Figure 23 and Figure 24 In some embodiments, there are two limit bars 113 , which are spaced apart from each other. The limit bars 113 extend from the first shell 11 toward the second shell 12 , and the support net 50 is at least partially disposed between the two limit bars 113 .

[0243] In this way, the installation position of the support net 50 can be more accurately defined by the two spaced-apart limiting bars 113 , ensuring that the support net 50 will not be offset or skewed during the installation process.

[0244] The spacing and extension direction of the two limiting bars 113 make installation of the support net 50 simpler and faster. During installation, the support net 50 simply needs to be aligned with the gap between the two limiting bars 113 and inserted. To remove, the support net 50 simply needs to be removed from between the two limiting bars 113. This design not only improves installation and removal efficiency but also reduces the risk of damage to the support net 50 due to improper installation.

[0245] Specifically, the distance between the two limiting strips 113 can be adjusted according to the thickness and width of the support net 50 to ensure the stability of the installation.

[0246] Please refer to Figure 23 and Figure 24 In some embodiments, the support net 50 includes a mesh portion 51 and a mounting portion 52 connected to the mesh portion 51 , the mesh portion 51 is disposed in the second limiting groove 114 , and the mounting portion 52 is mounted on the first shell 11 .

[0247] Thus, the design of the mounting portion 52 allows the support net 50 to adapt to different housing 10 structures. Even if the size or shape of the second retaining groove 114 of the housing 10 changes, as long as the mounting portion 52 can be fixed to the first shell 11, the support net 50 can still be used normally. This design improves the versatility and adaptability of the support net 50 and reduces production costs.

[0248] By dividing the support net 50 into a mesh portion 51 and a mounting portion 52, the installation of the support net 50 is made more stable. The mesh portion 51 is set in the second limiting groove 114 to ensure that it fits tightly against the vent 110, while the mounting portion 52 is directly fixed to the first housing 11, further enhancing the overall stability of the support net 50 and preventing the support net 50 from shifting or shaking during vibration or impact.

[0249] Specifically, the mesh portion 51 is the main portion of the support net 50 and is generally composed of a mesh structure, which is used to cover the vents 110. The mesh portion 51 allows air to circulate while preventing foreign matter from entering the interior of the housing 10 through the vents 110. The mesh portion 51 can be designed in various shapes and sizes, such as rectangular, circular, or irregular shapes, to accommodate different vent 110 designs.

[0250] The mounting portion 52 is another portion of the support net 50 and is used to secure the support net 50 to the first housing 11. The mounting portion 52 can be mounted to the first housing 11 by bolting, bonding, welding, or other methods. The number of mounting portions 52 can be one or more, such as two, three, four, or even more.

[0251] Please refer to Figure 22 、 Figure 23 and Figure 24 In some embodiments, the mesh portion 51 is provided with mesh holes 51 a , and the mesh holes 51 a are provided corresponding to the vents 110 .

[0252] In this way, the mesh portion 51 can be prevented from covering the vent 110 , thereby preventing the airflow from being affected at the vent 110 .

[0253] Specifically, the mesh 51a can be designed in various shapes and sizes, such as regular shapes such as circular holes and square holes, or irregular shapes. The size and shape of the mesh 51a can be the same as or different from the size and shape of the vent 110.

[0254] Please refer to Figure 23 and Figure 24 In some embodiments, the first housing 11 is provided with a stud 115 for mounting and connecting with the second housing 12 , and the mounting portion 52 is sleeved on the stud 115 .

[0255] In this way, by sleeve-mounting the mounting portion 52 on the stud 115 instead of using connecting components such as bolts or screws to connect the mounting portion 52 and the stud 115, the use of connecting components can be reduced, thereby reducing the manufacturing cost of the energy storage power supply 100.

[0256] Specifically, the stud 115 can be a hollow cylindrical structure with a threaded hole. The stud 115 is a structural component provided on the first housing 11 for mounting and connecting with the second housing 12 and supporting the mounting portion 52 of the support net 50. The shape and size of the stud 115 can be designed based on installation requirements, such as cylindrical, square, or hexagonal. The stud 115 can be designed as a separate component fixed to the first housing 11 or as an integral part of the first housing 11.

[0257] The sleeve can be a tight fit or a loose fit, depending on the installation requirements. The sleeve can be achieved with an interference fit, a clearance fit, or a transition fit.

[0258] The mounting portion 52 may be provided with a hole for engaging with the stud 115. The wall of the hole formed in the mounting portion 52 may contact the outer surface of the stud 115. The stud 115 may be provided with a threaded hole, which can be used to connect with a connecting member such as a bolt or screw. For example, the connecting member is a bolt. During the connection between the first housing 11 and the second housing 12, the bolt can be used to engage with the threaded hole in the stud 115, so that the head of the bolt can limit the mounting portion 52, thereby completing the fixing of the mounting portion 52.

[0259] Please refer to Figure 23 and Figure 24 In some embodiments, the first shell 11 includes a first substrate 111 and a first side panel 116 connected to the first substrate 111, the first side panel 116 is formed with a vent 110, the stud 115 includes a first stud 1150 and a second stud 1151, the first stud 1150 is arranged on the first substrate 111, and the second stud 1151 is arranged on the first side panel 116, the position height of the first stud 1150 is higher than the position height of the second stud 1151, and the number of the mounting portions 52 is two, one of the mounting portions 52 is sleeved on the first stud 1150, and the other mounting portion 52 is sleeved on the second stud 1151.

[0260] Thus, if the first studs 1150 and the second studs 1151 are positioned at the same height, a free end is easily formed on one side of the support net 50, which has a tendency to separate from the inner side surface of the housing 10. By providing the first studs 1150 and the second studs 1151 at different heights, the support net 50 can be more stably fixed, thereby preventing the support net 50 from separating from the inner side surface of the housing 10 when subjected to external forces, thereby preventing the support net 50 from malfunctioning.

[0261] Specifically, for a rectangular parallelepiped energy storage power supply 100, when the energy storage power supply 100 is placed horizontally, the first substrate 111 is located above the first side panel 116, and the first substrate 111 is substantially parallel to the horizontal plane. In this case, the height of the first stud 1150 and the height of the second stud 1151 both refer to the heights of the first stud 1150 and the second stud 1151 relative to the horizontal plane.

[0262] In some embodiments, the cooling fan 212 generates airflow through the vent 110. Thus, the airflow generated by the cooling fan 212 can flow out of the housing 10 from the vent 110, thereby accelerating the airflow inside and outside the housing 10, thereby improving heat dissipation efficiency.

[0263] Please refer to Figure 1 、 Figure 25 、 Figure 26 and Figure 27 In some embodiments, the energy storage power supply 100 further includes a handle assembly 60 and a shielding member 25. The housing 10 is provided with an open slot 14 located within the accommodating chamber 13; the handle assembly 60 includes a handle 61, a rotating shaft 62, and a fixing member 63. The rotating shaft 62 is inserted into the handle 61 and the housing 10. The handle 61 rotates relative to the housing 10 via the rotating shaft 62. One end of the rotating shaft 62 extends into the open slot 14. The fixing member 63 is provided on the rotating shaft 62. The fixing member 63 is located in the open slot 14 and abuts against the slot wall of the open slot 14 to limit the movement of the rotating shaft 62 along its own axial direction relative to the housing 10. The shielding member 25 is provided within the accommodating chamber 13 and closes the notch of the open slot 14.

[0264] In this way, by setting the fixing member 63 in the open groove 14 and setting the shielding member 25 to close the notch of the open groove 14, the fixing member 63 is prevented from accidentally falling out, thereby protecting the components inside the energy storage power supply 100 and improving the safety of the energy storage power supply 100.

[0265] Specifically, the number of the opening slots 14 can be one or more, such as two, three, four or even more. The shape of the opening slots 14 can be set according to demand, such as being set to regular shapes such as circular and square, or being set to irregular shapes.

[0266] The handle assembly 60 facilitates the user's carrying of the energy storage power supply 100. The handle 61 is secured with a rotating shaft 62 and a fixing member 63 to ensure stability and reliability. The handle 61 is the portion the user holds and can be made of a strong and durable material, such as plastic or rubber. The handle 61 facilitates the user's carrying of the energy storage power supply 100.

[0267] The rotating shaft 62 is a component connecting the handle 61 and the housing 10. The shape and material of the rotating shaft 62 can be selected according to needs. For example, the rotating shaft 62 can be a cylindrical metal or plastic shaft.

[0268] The fixing member 63 is a component used to secure the rotating shaft 62, such as a retaining ring 630 or a nut. The fixing member 63 can be an annular member made of metal or plastic. The fixing member 63 can abut the groove wall of the open groove 14 directly or indirectly. For example, a friction pad can be provided between the fixing member 63 and the groove wall of the open groove 14. The friction pad can abut the two side surfaces of the fixing member 63 adjacent to the groove wall of the open groove 14. In this way, the friction pad can prevent friction between the fixing member 63 and the groove wall of the open groove 14, thereby increasing the service life of the fixing member 63.

[0269] The shielding member 25 is a component used to close the notch of the opening slot 14. It can be a plate, sheet, mesh, or other shaped structure made of metal, plastic, rubber, etc. The shielding member 25 is used to prevent the fixing member 63 from falling out and protect the components inside the opening slot 14 from interference from external foreign objects.

[0270] Please refer to Figure 28 and Figure 29 In some embodiments, the shielding member 25 is disposed on the circuit board module 20 .

[0271] Thus, the shielding member 25 is provided on the circuit board module 20, further enhancing the protection of the circuit board module 20. Since the circuit board module 20 is a core component of the energy storage power supply 100 and is more susceptible to external interference, the provision of the shielding member 25 can effectively prevent external factors from affecting the circuit board module 20, thereby improving the reliability of the circuit board module 20.

[0272] Specifically, the shielding member 25 is mounted on the circuit board module 20 by mechanical fixing, bonding, or other means. The shielding member 25 can be directly connected to the circuit board module 20, for example, by screws, snaps, glue, etc.; or it can be connected to the inner wall of the housing 10 so as to be suspended on the circuit board module 20.

[0273] Please refer to Figure 27 In some embodiments, the fixing member 63 includes a snap ring 630 having a snap hole 631 on its circumference, and the snap ring 630 is clamped on the rotating shaft 62.

[0274] In this way, the fixing member 63 adopts a snap ring 630 design with a circumferential snap ring 631. The snap ring 630 is clamped on the rotating shaft 62, which can effectively limit the axial movement of the rotating shaft 62, thereby improving the stability of the fixing member 63 and preventing it from loosening or falling off during use.

[0275] Specifically, the snap ring 630 secures the rotating shaft 62 axially by engaging its bayonet 631. The bayonet 631 allows the snap ring 630 to elastically deform, facilitating its installation and removal. The snap ring 630 can be designed in various styles, such as shaft-mounted snap rings 630 and hole-mounted snap rings 630, to accommodate various installation locations and securing requirements.

[0276] The bayonet 631 can be one or more grooves. The bayonet 631 is designed to mate with corresponding structures on the shaft 62, elastically deforming and snapping into the grooves of the shaft 62 to achieve securement. The bayonet 631 can be designed to be evenly or unevenly distributed to accommodate varying shaft 62 diameters and securement requirements. The bayonet 631 can be circular, square, or other suitable shapes.

[0277] Please refer to Figure 29 In some embodiments, the housing 10 is provided with an adapter hole 15, the rotating shaft 62 is inserted into the adapter hole 15, and the handle assembly 60 further includes a damping member 64 sleeved on the rotating shaft 62, the damping member 64 is located in the adapter hole 15 and contacts the hole wall of the adapter hole 15.

[0278] Thus, the damping member 64 can provide a certain resistance, so that the handle 61 does not become too loose when it is rotated, thereby controlling the rotation speed and force of the handle 61 and improving the operational stability of the energy storage power supply 100. In addition, the resistance provided by the damping member 64 can give the handle 61 a certain damping feeling when it is rotated, improving the user experience when operating the handle 61 and making the operation smoother and more controllable.

[0279] Specifically, the adapter hole 15 is a hole in the housing 10 for inserting the rotating shaft 62. The adapter hole 15 provides a mounting location for the rotating shaft 62 and, through cooperation with the damping member 64, ensures the stability of the rotating shaft 62 and the damping effect of the rotation. The shape and size of the adapter hole 15 can be adjusted according to the specific design of the rotating shaft 62 and the damping member 64 to ensure the optimal fit. The adapter hole 15 can be designed to be circular, oval, or other suitable shapes.

[0280] The damping member 64 is a component used to provide resistance. The damping member 64 can be made of rubber, plastic or other materials with damping properties. The damping member 64 provides appropriate resistance by contacting the wall of the adapter hole 15, controls the rotation speed and force of the handle 61, and improves the stability and accuracy of the operation. The damping member 64 can be designed into various types, such as damping rings, damping sleeves, etc., to adapt to different rotating shafts 62 and adapter holes 15. The material and shape of the damping member 64 can be selected as needed to achieve different damping effects. The damping member 64 can be fixed to the rotating shaft 62 by interference fit, bonding or other means to ensure that it will not loosen or fall off during use.

[0281] Please refer to Figure 30 、 Figure 31 and Figure 32 In some embodiments, the handle 61 is provided with a pivot hole 610, and one of the hole wall of the pivot hole 610 and the circumferential surface of the rotating shaft 62 is provided with a stop groove 620, and the other is provided with a stop protrusion 611, which is clamped in the stop groove 620 to enable the handle 61 and the rotating shaft 62 to rotate synchronously.

[0282] Thus, by providing the stop groove 620 and the stop protrusion 611 between the wall of the pivot hole 610 of the handle 61 and the circumference of the rotating shaft 62, the synchronous rotation between the handle 61 and the rotating shaft 62 is ensured. This design can effectively prevent relative sliding between the handle 61 and the rotating shaft 62, thereby improving the reliability of operation.

[0283] Specifically, pivot hole 610 provides a mounting location for shaft 62 and, through cooperation with shaft 62, enables the rotation of handle 61. The shape and size of pivot hole 610 can be adjusted according to the specific design of shaft 62 to ensure an optimal fit. Pivot hole 610 can be designed to be circular, oval, or other suitable shapes.

[0284] The stop groove 620 is a groove formed in the wall of the pivot hole 610 or on the circumference of the rotating shaft 62. The stop groove 620 cooperates with the stop protrusion 611 to prevent relative slippage between the handle 61 and the rotating shaft 62, ensuring synchronized rotation. The stop groove 620 can be designed in a variety of shapes, such as circular, square, and dovetail, to accommodate different fixing requirements. The depth and width of the stop groove 620 can be adjusted according to actual needs.

[0285] The stop protrusion 611 is a protrusion on the wall of the pivot hole 610 or on the circumference of the rotating shaft 62. The stop protrusion 611 cooperates with the stop groove 620 to prevent relative slippage between the handle 61 and the rotating shaft 62, ensuring synchronized rotation. The stop protrusion 611 can be designed in a variety of shapes, such as round, square, and dovetail, to accommodate different fixing requirements. The height and width of the stop protrusion 611 can be adjusted according to actual needs.

[0286] Please refer to Figure 25 and Figure 27 In some embodiments, the handle 61 is disposed on the first housing 11 , and the first housing 11 is provided with an opening slot 14 .

[0287] Thus, during assembly, the handle 61 and the first housing 11 can be assembled first, and then the entire assembly can be connected to the second housing 12. This step-by-step assembly method can improve assembly efficiency and reduce assembly errors. In addition, the handle 61 and the opening slot 14 are both provided on the first housing 11, which can reduce the manufacturing complexity of the handle assembly 60 and improve manufacturing efficiency.

[0288] Please refer to Figure 25 and Figure 27 In some embodiments, the first side panel 116 is connected to the second housing 12 , the inner surface of the first substrate 111 is provided with a surrounding wall 1110 , the surrounding wall 1110 forms an open groove 14 , and the handle 61 is provided on the first substrate 111 .

[0289] In this way, the surrounding wall 1110 not only provides structural support for the opening slot 14, but also plays a certain protective role, preventing external objects from directly hitting the rotating shaft 62 and the fixing member 63 in the opening slot 14, thereby protecting the components located inside the opening slot 14.

[0290] Specifically, the surrounding wall 1110 can be set on the inner surface of the first substrate 111 by mechanical fixation, such as the surrounding wall 1110 is set on the inner surface of the first substrate 111 by bolt connection, bonding or clamping; the surrounding wall 1110 and the first substrate 111 can also be an integrally molded structure, which can reduce connection gaps and weak points, thereby enhancing the structural rigidity of the surrounding wall 1110.

[0291] The handle 61 can be disposed on the first substrate 111 via the rotating shaft 62 , or in other words, the handle 61 can rotate relative to the first substrate 111 via the rotating shaft 62 .

[0292] Please refer to Figure 30 In some embodiments, the rotating shaft 62 is provided with at least one weight-reducing groove 621 .

[0293] Thus, at least one weight-reducing groove 621 is provided on the rotating shaft 62 , which can effectively reduce the weight of the rotating shaft 62 , thereby reducing the weight of the entire energy storage power supply 100 , thereby improving the portability of the energy storage power supply 100 .

[0294] Specifically, the weight-reducing grooves 621 can be designed in various shapes and sizes, such as rectangular, semicircular, trapezoidal, etc., to meet different weight-reduction and heat-dissipation requirements. The depth and width of the weight-reducing grooves 621 can be adjusted according to actual needs. The number of weight-reducing grooves 621 can be one, two, three, or even more.

[0295] The weight-reducing groove 621 can be formed by machining, such as turning or drilling, etc. The weight-reducing groove 621 can also be formed by mold forming. For example, for a plastic shaft 62, the weight-reducing groove 621 can be directly formed during the injection molding process by designing an injection mold.

[0296] Please refer to Figure 33 、 Figure 34 and Figure 35 In some embodiments, the energy storage power supply 100 further includes a sliding button 80 and an elastic pressing member 90 . The housing 10 is provided with an assembly hole 16 ; the sliding button 80 is slidably mounted in the assembly hole 16 ; and the elastic pressing member 90 is disposed within the housing 10 and presses against the sliding button 80 .

[0297] Thus, the presence of the elastic pressing member 90 can provide a uniform elastic force, so that the sliding button 80 is always subjected to a stable pressing force during the sliding process. This design can effectively reduce the poor tactile feel of the sliding button 80 when sliding the sliding button 80, making the sliding force more uniform, so that the user will not feel obvious step differences or uneven resistance during operation, thereby reducing the risk of misoperation caused by uneven force, and thus improving the user's tactile feel during operation.

[0298] Specifically, the assembly hole 16 provides a mounting location for the sliding button 80 and limits the movement of the sliding button 80, allowing the sliding button 80 to slide within the housing 10. The shape and size of the assembly hole 16 can be designed based on the shape and size of the sliding button 80. For example, it can be a straight hole, a curved hole, or other hole types. The surface of the assembly hole 16 can be smoothed to reduce friction during the sliding of the sliding button 80.

[0299] The sliding button 80 is a slidable mechanical component used to control the on / off function or switching of the energy storage power supply 100. The sliding button 80 can be driven to slide along the path defined by the assembly hole 16. The sliding button 80 can be made of plastic or metal to meet different usage requirements.

[0300] The elastic pressing member 90 is an elastic member used to provide a stable pressing force. The elastic pressing member 90 can be made of a variety of elastic materials, such as plastic, rubber or silicone.

[0301] Please refer to Figure 35 In some embodiments, the elastic pressing member 90 includes a body 91 and an elastic arm 92 provided on the body 91 . The body 91 is mounted on the housing 10 , and the elastic arm 92 presses the sliding button 80 .

[0302] Thus, the elastic pressing member 90 is comprised of a main body 91 and an elastic arm 92. The main body 91 is mounted on the housing 10, while the elastic arm 92 directly presses against the sliding button 80. This allows the elastic arm 92 to more precisely control the distribution of the pressing force, further improving the uniformity of the force applied during the movement of the sliding button 80. The elastic deformation of the elastic arm 92 dynamically adjusts the pressing force, reducing the poor feel of the sliding button 80 caused by structural gaps or changes in friction.

[0303] Specifically, the body 91 and the elastic arm 92 can be connected by mechanical fixing means, such as bonding, welding, or clamping. The body 91 and the elastic arm 92 can also be an integrally formed structure, which can reduce connection gaps and weak points, thereby improving the overall structural rigidity of the elastic pressure member 90. The body 91 can be mounted on the housing 10 by bonding, welding, or threaded connection.

[0304] The elastic arm 92 can be made of a variety of elastic materials, such as spring steel, rubber, silicone, etc. The shape and size of the elastic arm 92 can be designed according to actual needs, for example, it can be corrugated, spring-shaped, sheet-shaped, etc.

[0305] Pressing refers to the state in which the elastic arm 92 applies pressure to the sliding button 80. By pressing, the elastic arm 92 can provide uniform pressing force to the sliding button 80, ensuring that the sliding button 80 feels smooth when being toggled, reducing the situation where the sliding button 80 feels poor when operating, thereby improving the user experience.

[0306] Please refer to Figure 35 In some embodiments, the body 91 is frame-shaped and has a hollow hole 910 , and both ends of the elastic arm 92 are connected to the hole wall of the hollow hole 910 .

[0307] Thus, the body 91 of the elastic pressure member 90 is frame-shaped and has a hollow hole 910. The ends of the elastic arm 92 are connected to the wall of the hollow hole 910. This design makes the deformation of the elastic arm 92 more concentrated and stable when subjected to force, thereby further optimizing the uniformity of force applied during the sliding button 80's operation. The presence of the hollow hole 910 can make the deformation of the elastic arm 92 more uniform, reduce local stress concentration, and further improve the poor feel when operating the sliding button 80.

[0308] Specifically, the body 91 is a component with a frame structure, and may be a rectangular, square, or other polygonal ring structure.

[0309] The hollow holes 910 are one or more openings on the body 91 that are used to connect the elastic arms 92 and optimize the deformation distribution. The presence of the hollow holes 910 can reduce the use of materials and reduce weight, while allowing the ends of the elastic arms 92 to be connected to the hole walls, making the deformation of the elastic arms 92 more concentrated and uniform when subjected to force. The shape and size of the hollow holes 910 can be designed according to actual needs. For example, they can be circular, square, oval, etc. The number of hollow holes 910 can also be adjusted as needed. For example, it can be one or more, such as two, three, four or even more.

[0310] The two ends of the elastic arm 92 can be connected to the hole wall of the hollow hole 910 by bonding, threading, plugging or other methods.

[0311] Please refer to Figure 35 In some embodiments, the elastic arm 92 is corrugated and has a trough portion 920 , and the trough portion 920 presses the sliding button 80 .

[0312] The corrugated structure allows the elastic arms 92 to deform more evenly when subjected to force, and the troughs 920 provide a more stable pressing force, further improving the uniformity of force applied during the movement of the slide button 80. This design effectively reduces the poor feel of the slide button 80, making the force applied more uniform and significantly improving the user experience.

[0313] Specifically, the trough 920 is the lowest point in the corrugated elastic arm 92, located in the concave portion of the corrugation. The trough 920 directly presses against the slide button 80, providing uniform pressure through its position and shape. The design of the trough 920 ensures that the deformation of the elastic arm 92 under force is more concentrated and stable, thereby reducing the poor feel when operating the slide button 80 and improving the user's operating experience.

[0314] Please refer to Figure 35 In some embodiments, a support platform 17 is provided on the inner surface of the shell 10 , and the body 91 rests on the support platform 17 .

[0315] Thus, the inner surface of the housing 10 is provided with a support platform 17, and the body 91 of the elastic pressing member 90 rests on the support platform 17. This design provides an additional support point for the elastic pressing member 90, making the elastic pressing member 90 more firmly installed in the housing 10, and further improving the stability of the overall structure of the elastic pressing member 90.

[0316] Specifically, the inner surface is the side of the shell 10 that faces the internal components of the energy storage power supply 100. The support platform 17 is a raised structure on the inner surface of the shell 10, which is used to support the main body 91 of the elastic pressure member 90. The support platform 17 can be integrally formed with the inner surface of the shell 10, or it can be connected to the inner surface of the shell 10 by mechanical fixation, such as bonding, bolting or clamping. The number of support platforms 17 can be one or more, such as two, three, four or even more. The support platform 17 can have different shapes and sizes, and can be regular shapes such as round, square, and long strips, or irregular shapes.

[0317] Please refer to Figure 35 In some embodiments, the elastic pressing member 90 includes two protrusions 93 provided on the body 91 , the two protrusions 93 are spaced apart, and the support platform 17 is sandwiched between the two protrusions 93 .

[0318] In this way, the spacing of the two protrusions 93 allows the support platform 17 to be precisely sandwiched between them. This structure ensures that the elastic pressure member 90 is accurately positioned during installation, reducing installation errors and improving assembly efficiency. In addition, the elastic pressure member 90 includes two spaced protrusions 93, with the support platform 17 sandwiched between these two protrusions 93. This design provides more stable support for the elastic pressure member 90, ensuring that the elastic pressure member 90 will not shift or wobble within the housing 10, thereby further improving the stability of the overall structure.

[0319] The bump 93 is a protrusion on the body 91 of the elastic pressure member 90, which is used to cooperate with the support platform 17 to provide stable support and positioning. The bump 93 can have different shapes and sizes, such as round, square, and elongated. The bump 93 can be integrally formed with the body 91 of the elastic pressure member 90, or it can be a separate component fixed to the body 91 by welding, bonding, or other means.

[0320] The support platform 17 can be clamped in different ways, such as directly clamped, clamped through an intermediate component, etc. The clamping force can be controlled by adjusting the shape and size of the protrusion 93.

[0321] Please refer to Figure 35 In some embodiments, the body 91 is provided with a through hole 911 , and the housing 10 is provided with a mounting post 18 , which is inserted into the through hole 911 .

[0322] Thus, during the production process, the elastic pressing member 90 can be first fixed to the housing 10 through the engagement of the mounting post 18 with the through hole 911 to form a pre-assembled component. This allows the pre-assembled component to be directly used when subsequently assembled with other components, greatly improving assembly efficiency and convenience.

[0323] Specifically, through-hole 911 is a through-hole formed in body 91 of elastic pressure member 90 for inserting mounting post 18. The shape and size of through-hole 911 can be designed based on the shape and size of mounting post 18, such as circular, square, or oval. The number of through-holes 911 can be set as needed. To stably secure mounting post 18, multiple through-holes 911 can be provided, such as two, three, four, or even more.

[0324] Mounting post 18 is a raised structure on housing 10 that is inserted into through-hole 911 to secure elastic pressure member 90. Mounting post 18 can have various shapes and sizes, such as round, square, or rectangular. The number of mounting posts 18 can match the number of through-holes 911. Mounting post 18 can be integrally formed with housing 10 or a separate component secured to housing 10 by welding, bonding, or other methods.

[0325] Please refer to Figure 35 、 Figure 36 and Figure 37 In some embodiments, the elastic pressure member 90 includes a pressure block 94 arranged on the side of the body 91 away from the sliding button 80. The elastic pressure member 90 is clamped between the housing 10 and the circuit board module 20, and the pressure block 94 abuts the circuit board module 20.

[0326] Thus, by abutting the circuit board module 20 with the pressing block 94, the elastic pressing member 90 is stably sandwiched between the housing 10 and the circuit board module 20. This design ensures that the elastic pressing member 90 does not shift or wobble within the housing 10, thereby ensuring its stable pressing action on the sliding button 80. Furthermore, the elastic pressing member 90 can be compressed by the circuit board module 20 without the need for additional components, which not only improves space utilization within the housing 10 but also reduces manufacturing costs.

[0327] Specifically, the pressing block 94 is a protruding portion on the body 91 of the elastic pressing member 90, which is used to contact and provide a force to the circuit board module 20. The pressing block 94 can have different shapes and sizes, such as round, square, and long strips.

[0328] The clamping means that the elastic pressing member 90 is clamped between the housing 10 and the circuit board module 20 and fixed by the pressure between the two.

[0329] Please refer to Figure 37 In some embodiments, the sliding button 80 and the circuit board module 20 are both disposed on the first housing 11 .

[0330] Thus, the sliding button 80 and the circuit board module 20 are both arranged on the first housing 11, making the assembly process more simplified. During assembly, the sliding button 80 and the circuit board module 20 can be installed on the first housing 11 first, and then connected to the second housing 12, reducing the complexity of the assembly steps and improving assembly efficiency.

[0331] Specifically, the sliding button 80 and the circuit board module 20 can be arranged on the first housing 11 by means of bolt connection, snap connection or bonding.

[0332] Please refer to Figure 35 In some embodiments, the body 91 is fixed to the housing 10 by fasteners.

[0333] In this way, the body 91 of the elastic pressing member 90 is fixed to the housing 10 by the fastener, which ensures the stability of the elastic pressing member 90 installed in the housing 10. The use of the fastener can prevent the elastic pressing member 90 from shifting or loosening during use, thereby ensuring its stable pressing effect on the sliding button 80.

[0334] Specifically, the fasteners may include bolts, screws, nuts or rivets, etc. The housing 10 may be provided with corresponding threaded holes or rivet holes, etc. The number of fasteners may be one or more, such as two, three, four or even more.

[0335] Please refer to Figure 5 、 Figure 6 and Figure 7 The energy storage power supply 100 according to the embodiment of the present invention includes a first housing assembly 103 and a second housing assembly 104. The first housing assembly 103 includes a first housing 11 and a circuit board module 20 fixed to the first housing 11; the second housing assembly 104 includes a second housing 12 and a battery module 30 fixedly mounted on the second housing 12. The first housing 11 and the second housing 12 are detachably connected and enclose a receiving chamber 13. The circuit board module 20 and the battery module 30 are both located in the receiving chamber 13.

[0336] In this way, the modular design of the first shell assembly 103 and the second shell assembly 104 allows the circuit board module 20 and the battery module 30 to be assembled separately and then installed as a whole, which simplifies the overall assembly process and improves assembly efficiency.

[0337] During assembly, the first shell 11 and the circuit board module 20 are assembled into the first shell assembly 103, and the second shell 12 and the battery module 30 are assembled into the second shell assembly 104, and then the first shell assembly 103 and the second shell assembly 104 are assembled together through the first shell 11 and the second shell 12.

[0338] Please refer to Figure 38 、 Figure 39 、 Figure 40 and Figure 41 The energy storage power supply 100 according to the embodiment of the present invention includes: a housing 10, a bracket 31, and battery cells 32. The battery cells 32 include first ends 320 and second ends 321 disposed opposite each other, and the first end 320 of each battery cell 32 includes a first electrode 3200 and a second electrode. The bracket 31 is provided with a fixing groove 310, and the housing 10 is provided with a plurality of mounting grooves 121. The assembly method of the energy storage power supply 100 according to the embodiment of the present invention includes:

[0339] S10, pre-fixing the first ends 320 of a plurality of battery cells 32 to the fixing grooves 310 of the bracket 31. The bracket 31 is provided with a plurality of electrical connectors 33, which connect the first electrodes 3200 of the battery cells 32 to the second electrodes of adjacent battery cells 32 one by one to form a battery module 30;

[0340] S20 , embed the second end 321 of the battery cell 32 in the mounting groove 121 and fix the bracket 31 to the housing 10 to fix the battery module 30 to the housing 10 .

[0341] In the assembly method of the energy storage power supply 100 according to the embodiment of the present invention, the first end 320 of the battery cell 32 is first pre-fixed to the fixing groove 310 of the bracket 31, and the positive second electrode of the battery cell 32 is connected via the electrical connector 33 on the bracket 31 to form the battery module 30. The battery module 30 is then fixed as a whole to the housing 10. This method avoids performing welding operations directly on the housing 10, reduces the risk of damage to the housing 10 due to welding, and improves assembly efficiency. At the same time, the provision of the fixing groove 310 and the electrical connector 33 on the bracket 31 allows for the rational arrangement of the positions of the battery cells 32 and the electrical connector 33, making the battery module 30 more compact, thereby facilitating a reduction in the overall volume of the energy storage power supply 100.

[0342] Specifically, during assembly, the first end 320 of the battery cell 32 can be pre-secured to the fixing groove 310 of the bracket 31 by means of snaps, bolts, or bonding. The electrical connector 33 can connect the first electrode 3200 of the battery cell 32 to the second electrode of the adjacent battery cell 32 one by one by means of welding or wire connection to form the battery module 30. The bracket 31 can be secured to the housing 10 by means of bolts, bonding, or snaps.

[0343] During pre-fixing, the fixing groove 310 and the battery cell 32 can be interference-fitted. Alternatively, glue can be applied to the fixing groove 310 and fixed by gluing. Alternatively, a jig can be provided and pre-fixed to the bracket 31 by connecting the jig to the bracket 31. The jig can then be removed after welding is complete.

[0344] Please refer to Figure 41 and Figure 42 In certain embodiments, the assembly method comprises:

[0345] S30, installing the electrical connector 33 on the bracket 31;

[0346] S40 , welding the electrical connector 33 to the first electrode 3200 of the battery cell 32 and the second electrode of the adjacent battery cell 32 .

[0347] It should be noted that there is no time sequence relationship between steps S30, S40 and step S10. For example, step S30 can be placed before or after step S10. Step S40 can be placed before or after step S10.

[0348] Thus, by first installing the electrical connector 33 on the bracket 31, the first electrode 3200 of the battery cell 32 is welded to the second electrode of the adjacent battery cell 32. This method ensures that the electrical connector 33 is installed in the correct position, preventing the battery cell 32 from shifting due to movement of the electrical connector 33 during welding, thereby ensuring that the battery cell 32 is installed in the correct position. Furthermore, welding can ensure a stable electrical connection between the first electrode 3200 and the second electrode.

[0349] Specifically, the electrical connector 33 can be mounted on the bracket 31 by plugging, snapping, or other methods. Welding is a process that combines materials by applying heat or pressure, and is used to enhance the connection strength and conductivity between the electrical connector 33 and the first and second electrodes 3200. Welding ensures the long-term stability and reliability of the electrical connection. Welding methods can include resistance welding, laser welding, and ultrasonic welding.

[0350] Please refer to Figure 41 In some embodiments, mounting the electrical connector 33 on the bracket 31 includes:

[0351] The first positioning structure 330 of the electrical connector 33 is mated and connected with the second positioning structure 312 of the bracket 31 , so that the electrical connector 33 is positioned and mounted on the bracket 31 .

[0352] In this way, by cooperating and connecting the first positioning structure 330 of the electrical connector 33 with the second positioning structure 312 of the bracket 31, the electrical connector 33 can be quickly and accurately positioned, reducing the time for finding and adjusting the position during assembly and significantly improving assembly efficiency.

[0353] Specifically, the first positioning structure 330 is a component on the electrical connector 33 that cooperates with the second positioning structure 312 of the bracket 31 to ensure accurate positioning of the electrical connector 33 during installation. The first positioning structure 330 can be a protrusion, a groove, a hole, or other structures.

[0354] The second positioning structure 312 is a component on the bracket 31 used to cooperate with the first positioning structure 330 of the electrical connector 33 to ensure accurate positioning of the electrical connector 33 during installation. The second positioning structure 312 can be a groove, protrusion, hole, etc. that matches the first positioning structure 330.

[0355] In one example, the first positioning structure 330 is a protrusion and the second positioning structure 312 is a hole. During assembly, the protrusion is inserted into the hole to complete the mating connection between the first positioning structure 330 and the second positioning structure 312 , thereby completing the positioning of the electrical connector 33 .

[0356] Please refer to Figure 41 In some embodiments, the first positioning structure 330 is a protrusion and the second positioning structure 312 is a positioning hole. The first positioning structure 330 of the electrical connector 33 is connected to the second positioning structure 312 of the bracket 31 by mating, including:

[0357] Insert the protrusion into the positioning hole.

[0358] In this way, the protrusions cooperate with the positioning holes to simplify the connection process between the electrical connector 33 and the bracket 31, thereby reducing assembly complexity. In addition, since no additional connecting elements (such as screws, bolts, etc.) are required, this method can reduce manufacturing costs.

[0359] Please refer to Figure 43 In some embodiments, before installing the battery module 30 on the housing 10, the assembly method further includes:

[0360] The collection assembly 105 is mounted on the bracket 31 and connected to the electrical connector 33 .

[0361] In this way, the acquisition component 105 is pre-installed on the bracket 31 and connected to the electrical connector 33, which reduces the subsequent steps of complex wiring and installation on the housing 10 and significantly improves assembly efficiency.

[0362] Specifically, the acquisition component 105 is used to monitor and collect data from the battery module 30. This data includes, but is not limited to, voltage, current, and temperature. The acquisition component 105 may include a voltage acquisition module, a temperature sensor, or a current sensor. The acquisition component 105 may be mounted to the bracket 31 using methods such as snap fastening, bolting, or adhesive fastening.

[0363] Please refer to Figure 5 、 Figure 6 and Figure 44 In some embodiments, the energy storage power supply 100 further includes a circuit board module 20, the housing 10 includes a first housing 11 and a second housing 12, and the second housing 12 is formed with a mounting groove 121. The assembly method includes:

[0364] S101, fixing the circuit board module 20 to the first housing 11; fixing the bracket 31 to the housing 10 to fix the battery module 30 to the housing 10 (step S20), including:

[0365] S21 , fixing the bracket 31 to the second housing 12 to fix the battery module 30 to the second housing 12 .

[0366] Thus, the first housing 11 and the second housing 12 can serve as independent units of the circuit board module 20 and the battery module 30, respectively. This modular design allows the battery module 30 and the circuit board module 20 to be assembled separately, simplifying the assembly process and improving assembly efficiency.

[0367] In some embodiments, after securing the bracket 31 to the second housing 12 to secure the battery module 30 to the second housing 12 , the assembly method further includes:

[0368] The battery module 30 and the circuit board module 20 are connected by a wiring harness, and then the first housing 11 and the second housing 12 are assembled so that the battery module 30 and the circuit board module 20 are located in the accommodating chamber 13 formed by the first housing 11 and the second housing 12 .

[0369] Thus, arranging the electrical connection step before assembling the housing 10 can avoid complicated wiring and connection operations within the limited space of the housing 10, simplify the assembly process, improve assembly efficiency, and also facilitate the inspection and adjustment of the quality of the electrical connection.

[0370] Please refer to Figure 2 、 Figure 9 and Figure 45 In some embodiments, the first housing 11 includes a first substrate 111 and a panel 112 connected to the first substrate 111, the panel 112 is connected to the second housing 12, and the circuit board module 20 includes a first circuit board 21 and a second circuit board 22 fixedly connected to the first circuit board 21, and the first circuit board 21 and the second circuit board 22 are arranged at a certain angle;

[0371] Fixing the circuit board module 20 to the first housing 11 (step S101 ) includes:

[0372] S1010, fixing the first circuit board 21 to the first substrate 111;

[0373] S1011 , fixing the second circuit board 22 to the panel 112 .

[0374] In this way, the circuit board module 20 is divided into a first circuit board 21 and a second circuit board 22, which are respectively fixed to the first base plate 111 and the panel 112, making the installation and removal process more convenient. When maintaining or replacing the circuit board module 20, the corresponding circuit boards can be operated separately, reducing maintenance difficulty and cost and improving maintenance efficiency.

[0375] In some embodiments, one of the first circuit board 21 and the second circuit board 22 is provided with a plug hole 210, and the other is provided with a plug protrusion 220. The assembly method includes:

[0376] S50, inserting the plug protrusion 220 into the plug hole 210;

[0377] S60 , soldering is used to constrain the insertion protrusion 220 in the insertion hole 210 .

[0378] In this way, through the cooperation between the plug-in protrusion 220 and the plug-in hole 210, the mechanical connection between the first circuit board 21 and the second circuit board 22 is first achieved. This preliminary fixation makes the positional relationship between the two circuit boards more stable, and it is not easy to deviate during the subsequent soldering process, thereby improving the assembly accuracy and stability.

[0379] After the insertion protrusion 220 is inserted into the insertion hole 210, it is fixed using soldering. This dual connection method not only enhances the mechanical connection strength but also ensures the reliability of the electrical connection. Soldering can provide good conductivity, reduce contact resistance, and ensure stable electrical performance between the circuit boards.
