[0075] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The energy storage power supply 100 of this embodiment includes a housing 10, a circuit board module 20, and a battery module 30. The housing 10 includes a first outer shell 11 and a second outer shell 12 detachably connected to the first outer shell 11, the first outer shell 11 and the second outer shell 12 forming a receiving chamber 13; the circuit board module 20 includes an inverter circuit 2141 (e.g., ...). Figure 10a The circuit board module 20 is fixedly mounted on the first housing 11 and located in the receiving chamber 13; the battery module 30 is fixedly mounted on the second housing 12 and located in the receiving chamber 13, and the battery module 30 is electrically connected to the circuit board module 20.

[0076] In the energy storage power supply 100 of this utility model embodiment, the modular design of the energy storage power supply 100 is achieved by designing the housing 10 as a detachable first outer shell 11 and a second outer shell 12, and fixing the circuit board module 20 and the battery module 30 onto the corresponding outer shells respectively. This design allows for the pre-assembly of the circuit board module 20 with the first outer shell 11 and the battery module 30 with the second outer shell 12 independently during the assembly process, and then the overall assembly of the circuit board module 20 with the first outer shell 11 and the battery module 30 with the second outer shell 12 is combined, thereby simplifying the overall assembly process, significantly reducing assembly complexity, and significantly improving assembly efficiency.

[0077] Specifically, the housing 10 is the external protective structure of the energy storage power supply 100, used to house 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.

[0078] The detachable 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, etc. The receiving chamber 13 is the internal space enclosed by the first housing 11 and the second housing 12. This receiving space is used to accommodate the circuit board module 20 and the battery module 30, providing a protected internal environment.

[0079] The circuit board module 20 is the control and management core of the energy storage power supply 100, containing various electronic components and control circuits. The circuit board module 20 can be used for power conversion, control, and management, ensuring the normal operation of the energy storage power supply 100. The circuit board module 20 can be fixedly installed on the first housing 11 by means of bolt connection, snap-fit ​​connection, or plug-in connection.

[0080] Inverter circuit 2141 is a circuit that converts direct current (DC) to alternating current (AC). Inverter circuit 2141 can convert AC to DC, enabling energy storage power supply 100 to adapt to different power needs. It can convert the DC power from battery module 30 into AC power for external output, and it can also convert external AC power input into DC power to supply power to battery module 30.

[0081] The battery module 30 is an energy storage unit of the energy storage power supply 100, and may include multiple battery cells 32. The battery module 30 stores electrical energy to support the output of the energy storage power supply 100. The battery module 30 can use lithium-ion batteries, lead-acid batteries, or other types of batteries, depending on the energy storage requirements and application scenario. The battery module 30 can be fixedly installed on the second housing 12 by means of bolt connection, snap-fit ​​connection, or plug-in connection.

[0082] Electrical connection refers to establishing an electrical path between circuit board module 20 and battery module 30 through electrical components such as wires and connectors, enabling the transmission of electrical energy and signals between them. Through electrical connection, circuit board module 20 can control and manage battery module 30, ensuring stable power transmission. Electrical connection between circuit board module 20 and battery module 30 can be achieved through methods such as soldering, bolting, terminal block connection, or wire connection.

[0083] Please refer to Figure 5 , Figure 6 and Figure 7 During assembly, firstly, the circuit board module 20 can be fixedly mounted on the first housing 11, and the battery module 30 can be fixedly mounted on the second housing 12. Then, the first housing 11 and the second housing 12 can be detachably connected and assembled into a complete housing 10, forming a receiving chamber 13. Finally, the circuit board module 20 and the battery module 30 can be connected by electrical connection to complete the assembly of the energy storage power supply 100.

[0084] In use, the battery module 30 stores electrical energy and transmits it to the circuit board module 20 via an electrical connection. The circuit board module 20 converts, controls, and manages the electrical energy to ensure a stable output of power.

[0085] Please refer to Figure 1 and Figure 4 In some embodiments, the first housing 11 is formed with a vent 110 communicating with the receiving chamber 13.

[0086] Thus, by providing a vent 110 on the first outer casing 11, air circulation can be promoted, effectively reducing the temperature inside the containment chamber 13, thereby improving the heat dissipation performance of the energy storage power supply 100, thereby enhancing the operational stability of the energy storage power supply 100 and extending the service life of the internal components of the energy storage power supply 100.

[0087] Specifically, the vent 110 is an opening provided on the first housing 11 to facilitate air circulation. The vent 110 can be designed as a louver, mesh, or other form to prevent foreign objects from entering the equipment. There can be one or more vents 110; for example, there can be two vents 110 spaced apart on the first housing 11. The shape of the vent 110 can be regular, such as circular or square, or irregular.

[0088] Please refer to Figure 4 In some embodiments, the vent 110 includes an air inlet 1100 and an air outlet 1101, which are located on opposite sides of the first housing 11.

[0089] Thus, the air inlet 1100 and the air outlet 1101 are located on opposite sides of the first housing 11. This design creates a longer airflow path, allowing air to flow through most of the interior of the energy storage power supply 100, thereby significantly improving heat dissipation efficiency.

[0090] Specifically, the opposite sides can be the front and rear sides, left and right sides, or top and bottom sides of the energy storage power supply 100. For example, for a cuboid energy storage power supply 100, the air inlet 1100 and the air outlet 1101 can be set on the left and right sides of the energy storage power supply 100, or the air inlet 1100 and the air outlet 1101 can be set at intervals along the length of the energy storage power supply 100.

[0091] 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.

[0092] Thus, by designing the first housing 11 as a combination of the first substrate 111 and the panel 112, the circuit board module 20 can be pre-installed on the first substrate 111, and then the panel 112 can be assembled with the second housing 12 to form a complete housing. This step-by-step assembly method simplifies the assembly process, reduces assembly complexity, and improves assembly efficiency.

[0093] Specifically, the first substrate 111 is part of the first outer shell 11 and can be a flat plate-like structure. The shape of the first substrate 111 can be a regular shape such as rectangle or circle, or it can be an irregular shape. For example, the shape of the first substrate 111 is rectangular. 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 mounting 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-in connection.

[0094] Panel 112 is another part of the first outer shell 11 and can be a flat plate-like structure. The shape of panel 112 can be a regular shape such as rectangle or circle, or it can be an irregular shape. For example, panel 112 is rectangular. Panel 112 can be connected to the second outer shell 12 by means of bolt connection, snap connection, or plug connection.

[0095] 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.

[0096] Thus, by dividing the circuit board module 20 into a first circuit board 21 and a second circuit board 22, and fixing them respectively on the first substrate 111 and the panel 112, distributed installation of the circuit boards can be achieved. This distributed installation method allows different circuit board parts to be processed separately during the assembly process, thereby simplifying the assembly steps and improving assembly efficiency.

[0097] 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 preset angle. For example, the included angle between the first circuit board 21 and the second circuit board 22 can be 45 degrees, 60 degrees, 90 degrees or other angles.

[0098] The first circuit board 21 and the second circuit board 22 can be electrically connected by means of welding, bolting, terminal block connection or wire connection.

[0099] In some embodiments, the first circuit board 21 is fixed to the first substrate 111 by screws.

[0100] In some embodiments, the second circuit board 22 is fixed to the panel 112 by screws.

[0101] 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.

[0102] Thus, screw fastening provides a robust mechanical connection, ensuring the circuit board remains stable even under complex environments such as vibration and impact, preventing electrical faults caused by loose connections. Furthermore, screw fastening is a common method of securing components; the tools are readily available, the operation is simple, and installation and maintenance are convenient. When replacing or repairing the circuit board, disassembly can be completed simply by loosening the screws, improving maintenance efficiency.

[0103] Specifically, the number of screws can be one or more, such as two, three, four, or even more. Multiple screws can provide multiple connection points, thereby increasing the strength of the connection. Screw fastening can be combined with accessories such as washers and spring washers to enhance the fixing effect.

[0104] Please refer to Figure 1 and Figure 9 In some embodiments, the panel 112 has 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.

[0105] Thus, the output port 102a is directly opposite the open port 112a on the panel 112, which allows users to make external connections directly through the open port 112a without the need for additional adapters or complicated wiring, thus enhancing the user experience.

[0106] Specifically, the angle between the first circuit board 21 and the second circuit board 22 can be 30 degrees, 60 degrees, 90 degrees or 120 degrees, etc.

[0107] The opening 112a can be an opening made on the panel 112. There can be one or more openings 112a. The number of openings 112a can correspond one-to-one with the number of output ports 102a.

[0108] Output port 102a can be either USB port 101 or vehicle charging port 102.

[0109] 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.

[0110] Thus, by arranging the first circuit board 21 horizontally and the second circuit board 22 vertically, the three-dimensional space inside the energy storage power supply 100 can be utilized more effectively, avoiding overlap and interference between circuit boards and improving space utilization. Furthermore, the horizontal and vertical layout makes the installation and maintenance of the circuit boards more convenient. Maintenance personnel can more easily access and operate different circuit boards without disassembling other components, improving maintenance efficiency.

[0111] Specifically, horizontal mounting means that the first circuit board 21 is mounted horizontally. By horizontal mounting, the first circuit board 21 can make more efficient use of horizontal space and avoid interference with other components.

[0112] Vertical mounting refers to the second circuit board 22 being installed in a vertical direction. By mounting it vertically, the second circuit board 22 can make more efficient use of vertical space and optimize the overall layout.

[0113] Please refer to Figure 2 In some embodiments, both the first circuit board 21 and the second circuit board 22 are fixed to the first housing 11.

[0114] Thus, 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, avoids overlap and interference between the circuit boards, and further improves the utilization rate of the internal space of the energy storage power supply 100.

[0115] If the first housing 11 and the second housing 12 were not detachable, the second housing 12 would interfere with the installation of the first circuit board 21 and the second circuit board 22. Therefore, the detachable connection of the first housing 11 and the second housing 12 allows the first circuit board 21 and the second circuit board 22 to be pre-fixed to the first housing 11, and then the second housing 12 to be connected to the first housing 11, thereby completing the assembly of the entire energy storage power supply 100. This modular design improves production efficiency and reduces assembly time.

[0116] Specifically, both the first circuit board 21 and the second circuit board 22 can be fixed to the first housing 11 by means of bolt connection, snap connection or plug connection.

[0117] 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 hole 210, and the other is provided with a plug protrusion 220. The plug protrusion 220 is inserted into the plug hole 210 to fix the first circuit board 21 and the second circuit board 22 together.

[0118] Thus, the design of the insertion hole 210 and the insertion protrusion 220 allows for quick connection and disconnection between circuit boards without the use of tools, significantly improving the efficiency of assembly and maintenance.

[0119] Specifically, the socket 210 is an opening or recess on the circuit board for accommodating the protrusion 220. The socket 210 can be designed in different shapes (such as round, square, rectangular, etc.) and sizes to accommodate different protrusions 220. The protrusion 220 is a protrusion on the circuit board for inserting into the socket 210. There can be multiple sockets 210 and protrusions 220.

[0120] Please refer to Figure 10 In one example, the first circuit board 21 has a connector hole 210, and the second circuit board 22 has a connector protrusion 220. In another example, the first circuit board 21 has a connector protrusion 220, and the second circuit board 22 has a connector hole 210. The connector protrusion 220 is fixed in the connector hole 210 by soldering. The first circuit board 21 also has a female connector 21a, and the second circuit board 22 also has a male connector 22a. The electrical connection between the first circuit board 21 and the second circuit board 22 is achieved by inserting the male connector 22a into the female connector 21a. During installation, the connection is completed simply by inserting the male connector 22a into the slot of the female connector 21a, without the need for additional tools or equipment, making it convenient and quick.

[0121] Please refer to Figure 11 In some embodiments, the second housing 12 is provided with a plug-in slot 120, and the second circuit board 22 is inserted into the plug-in slot 120 at the edge away from the first circuit board 21.

[0122] Thus, the plug-in method simplifies the installation and removal process of the second circuit board 22, making the position of the second circuit board 22 stable, without the need for additional fixing tools or complicated connection steps, and significantly improving assembly efficiency.

[0123] Specifically, the insertion slot 120 is a recess provided on the second housing 12 to accommodate 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 the 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 the processing errors of the second circuit board 22.

[0124] The insertion groove 120 can be formed on the inner surface of the second housing 12, or it can be formed in other ways. For example, two posts are provided on the inner surface of the second housing 12, and the two posts are provided with mutually aligned insertion grooves 120.

[0125] Please refer to Figure 10aIn some embodiments, the first circuit board 21 includes a functional circuit 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 and is used 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 and is used to convert AC power to DC power. The solar charging circuit 2142 is electrically connected to the battery module 30 through the battery management circuit 2140 and is used to maximize the electrical energy generated by the solar panel. Thus, by integrating the battery management circuit 2140, inverter circuit 2141, and solar charging circuit 2142 onto the first circuit board 21, a multifunctional integrated design is achieved. This integrated design reduces the number of components, simplifies the circuit layout, improves the compactness and reliability of the device, and increases assembly efficiency.

[0126] The battery management circuit 2140 can monitor 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 battery life and improve battery reliability and safety. The solar charging circuit 2142 is designed to maximize the electrical energy 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.

[0127] Specifically, the battery management circuit 2140 is a circuit used to monitor and manage 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, and can control the charging and discharging process of the battery module 30 to extend its lifespan. The battery management circuit 2140 may include functions such as overcharge protection, over-discharge protection, and short-circuit protection.

[0128] The solar charging circuit 2142 is a circuit used to convert electrical energy generated by a solar panel into electrical energy suitable for storage in the battery module 30. The solar charging circuit 2142 can be connected to a solar panel that converts solar energy into electrical energy, and the solar charging circuit is used to convert the electrical energy from the solar panel into electrical energy that can be stored in the energy storage power supply 100.

[0129] In some embodiments, the second circuit board 22 includes an output circuit, a display screen, and buttons. 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 of the energy storage power supply 100 and the amount of electricity. The buttons can be used to control the working status of the energy storage power supply 100.

[0130] In this way, the output circuit allows the energy storage power supply 100 to be directly connected to an external circuit, and users can easily use the energy storage power supply 100 to power various devices without the need for additional adapters or complicated connection steps, thus improving ease of use.

[0131] Specifically, the output circuit refers to the circuit used to transmit electrical energy from the energy storage power supply 100 to external devices. The output circuit may include various interfaces, such as USB interface, DC output interface, AC output interface, etc., to adapt to different device requirements.

[0132] External circuit electrical connection refers to the electrical connection between the energy storage power supply 100 and external devices. External circuit electrical connection can be wired or wireless. Wired connection includes USB cable, power adapter cable, etc.

[0133] The output power of the output circuit can be adjusted according to specific needs, such as supporting 5V / 2A USB output or 12V / 10A DC output. It should be noted that the values ​​here are merely examples for ease of understanding and should not be considered as limiting the embodiments of this utility model.

[0134] Please refer to Figure 10a In some embodiments, the second circuit board 22 includes a DC-DC conversion circuit 22b, which is electrically connected to the battery module 30 through the battery management circuit 2140, and outputs the power of the battery module 30 to the outside through the output port 102a after DC conversion.

[0135] In this way, the electrical energy after DC conversion can be used to power various DC devices, such as mobile devices and lighting equipment, through the output port 102a, which enhances the versatility and practicality of the energy storage power supply 100 and makes it suitable for a variety of application scenarios.

[0136] Please refer to Figure 1 In some embodiments, the output circuitry includes at least one of a USB port 101 and a vehicle charging port 102. In one embodiment, the USB port 101 is exposed via a panel 112. In one embodiment, the vehicle charging port 102 is exposed via a panel 112. In another embodiment, both the USB port 101 and the vehicle charging port 102 are exposed via a panel 112.

[0137] In this way, by integrating the USB port 101 and the vehicle charging port 102, the reliance on external adapters or converters is reduced, thus lowering the user's operating costs.

[0138] Specifically, USB Port 101 is a universal serial bus interface used to connect various USB devices. USB Port 101 provides a standardized interface, facilitating the connection and charging of various USB devices, such as mobile phones, tablets, and laptops. USB Port 101 supports multiple standards, such as USB-A, USB-C, and USB-B, with common output power options including 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.

[0139] The vehicle charging port 102 is a charging interface specifically designed for in-vehicle devices, providing a convenient charging interface for vehicles. It allows users to charge their devices in the vehicle environment. The vehicle charging port 102 supports 12V and 24V outputs and can be designed to support various in-vehicle devices, such as mobile phones, tablets, and car navigation systems.

[0140] 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 housing 12 is formed with a plurality of mounting slots 121. The other end of the battery cell 32 is embedded in the mounting slot 121. The bracket 31 is fixedly mounted on the second housing 12 to fix the plurality of battery cells 32 to the second housing 12.

[0141] Thus, the bracket 31 design allows multiple battery cells 32 to be pre-installed on one end of the bracket 31 during the assembly process, and then the entire battery module 30 is embedded in the mounting slot 121 to fix the entire battery module 30 on the second housing 12, which simplifies the assembly steps and improves the assembly efficiency.

[0142] The mounting slot 121 simplifies the installation process of the battery cell 32. Simply insert one end of the battery cell 32 into the mounting slot 121 to secure it, eliminating the need for additional tools or complex connection steps, significantly improving assembly efficiency. Furthermore, the mounting slot 121 design allows one end of the battery cell 32 to be firmly embedded in the second housing 12, preventing displacement or loosening of the battery cell 32 under vibration or impact, thus improving the installation stability of the battery module 30.

[0143] 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 shift or loosen during operation;

[0144] The bracket 31 can be fixedly installed on the second housing 12 by means of bolt connection, snap connection or plug connection. The bracket 31 and the second housing 12 can also be integrally formed, which can reduce the connection gap and weak point 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.

[0145] Multiple mounting slots 121 can correspond one-to-one with multiple battery cells 32. The mounting slots 121 can be formed through the inner wall of the second housing 12 and rib structures provided on the inner wall of the second housing 12. The mounting slots 121 are used to fix the battery cells 32. The wall of the mounting slot 121 can be larger than the diameter of the battery cell 32. The shape of the inner wall of the mounting slot 121 can be similar to the shape of the outer surface of the battery cell 32. The number of mounting slots 121 can be two, three, four, or even more.

[0146] 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 has a mounting groove 121 and is connected to the first housing 11.

[0147] Thus, the mounting slot 121 on the second side plate 123 can optimize the layout of the battery cell 32, making the connection between the battery cell 32 and the casing more compact, reducing unnecessary space occupation and improving space utilization.

[0148] Furthermore, by designing the second housing 12 as a combination of the second substrate 122 and the second side plate 123, the battery cells 32 can be installed in stages. This staged installation method allows different component parts to be processed separately during the assembly process, thereby simplifying the assembly steps and improving assembly efficiency.

[0149] Specifically, the second substrate 122 is part of the second housing 12, and is typically a flat plate-like structure. The shape of the second substrate 122 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 second substrate 122 is rectangular.

[0150] The second side plate 123 is another part of the second outer shell 12. It can be a plate-like structure perpendicular to the second base plate 122, used to connect with the first outer shell 11 and form part of the receiving chamber 13. The second side plate 123 and the first outer shell 11 can be connected by means of bolt connection, snap connection or plug connection.

[0151] Please refer to Figure 12In some embodiments, the second substrate 122 is provided with a support rib 1221, and the support rib 1221 forms a first limiting groove 1222, with the battery cell 32 abutting against the groove wall of the first limiting groove 1222.

[0152] Thus, the support rib 1221 not only provides heat dissipation but also provides pre-positioning for the battery cell 32, thereby facilitating the installation of the battery cell 32.

[0153] Specifically, the number of support ribs 1221 can be one or more. For example, there can be two support ribs 1221, which are arranged in parallel on the surface of the second substrate 122 facing the battery cell 32. Each support rib 1221 has a plurality of first limiting grooves 1222, and each first limiting groove 1222 is used to limit the 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.

[0154] The shape of the first limiting groove 1222 can match the shape of the outer peripheral surface of the battery cell 32. For example, the battery cell 32 can be cylindrical, and the shape of the first limiting groove 1222 can be arc-shaped.

[0155] 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. The second end 321 of the battery cell 32 forms 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 the second end 321 and the bottom of the mounting groove 121 are separated by a certain distance to form a pressure relief groove 121b. The pressure relief groove 121b communicates with the receiving chamber 13.

[0156] Thus, when a single battery cell 32 experiences thermal runaway, the resulting high-pressure gas can be promptly discharged through the pressure relief groove 121b, preventing gas accumulation inside the battery module 30 and potential explosion, significantly improving the safety performance of the energy storage power supply 100 under thermal runaway conditions. Furthermore, the pressure relief groove 121b can connect to the pressure relief structures 32a of multiple single battery cells 32, allowing any single battery cell 32's pressure relief structure 32a within the battery module 30 to achieve uncontrolled pressure relief.

[0157] Specifically, the pressure relief structure 32a can be an explosion-proof valve or a groove 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 weak device inside. When the pressure in the battery cell 32 increases, the weak point will be forced open by the pressure, thereby releasing the high-pressure gas in the battery cell 32 to prevent the battery cell 32 from exploding or catching fire due to abnormal conditions such as overcharging, over-discharging, or short circuit. As another example, the pressure relief structure 32a can be a groove formed by machining at the second end 321 of the battery cell 32, where the aforementioned weak point is formed.

[0158] The support structure 121a may be a protrusion protruding from the inner wall of the receiving chamber 13. For example, the support structure 121a may be a rib protruding from the inner wall of the receiving chamber 13, so that the support structure 121a can be used to support the battery cell 32, and one end of the battery cell 32 is spaced apart from the inner wall of the receiving chamber 13, so that a pressure relief groove 121b can be formed between the battery cell 32 and the inner wall of the receiving chamber 13.

[0159] Please refer to Figure 12 In some embodiments, a notch 121c is provided on the side wall of the mounting groove 121, and the pressure relief groove 121b communicates with the receiving chamber 13 through the notch 121c.

[0160] Thus, by providing a notch 121c on the side wall of the mounting groove 121 to connect the pressure relief groove 121b with the receiving chamber 13, this design is relatively simple and easy to implement in the production process. Compared with complex internal air guiding channels or other pressure relief structures 32a, the notch 121c is easier to process, reducing the complexity of the manufacturing process, lowering production costs, and improving production efficiency. Furthermore, the pressure relief and heat dissipation performance can be optimized by adjusting the size, shape, and position of the notch 121c to adapt to different working environments and safety standards.

[0161] Specifically, the number of notches 121c can be one or more. For example, the number of notches 121c can be two, three, four or even more. Multiple notches 121c can be symmetrically formed on the side wall of the mounting groove 121, which can improve the pressure relief effect.

[0162] Please refer to Figure 12 In some embodiments, multiple mounting slots 121 are arranged side by side, and two adjacent mounting slots 121 are connected by a notch 121c. The notch 121c on the side wall of one of the mounting slots 121 is connected to the receiving chamber 13.

[0163] Thus, by opening a notch 121c on the side wall of the mounting groove 121 to connect the pressure relief groove 121b with the receiving chamber 13, the high-pressure gas ejected from the battery cell 32 can be guided out of the pressure relief groove 121b to achieve the purpose of pressure relief.

[0164] Furthermore, by arranging multiple mounting slots 121 side by side, and connecting adjacent mounting slots 121 through a notch 121c, with the notch 121c on the side wall of one of the mounting slots 121 communicating with the receiving 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 receiving chamber 13 through the notch 121c of its own pressure relief slot 121b, but also diffuse and discharge into the entire pressure relief channel sequentially through the notches 121c of adjacent mounting slots 121.

[0165] Specifically, the size of the notch 121c connecting two adjacent mounting slots 121 and the size of the notch 121c connecting the receiving chamber 13 can be the same or different. The notch 121c can be formed by machining or by injection molding. The shape of the notch 121c can be arbitrarily set according to requirements, and this embodiment of the utility model does not limit it.

[0166] Please refer to Figure 12 and Figure 14 In some embodiments, the sidewall of the mounting groove 121 forms a gap with the sidewall of the battery cell 32, and the pressure relief groove 121b communicates with the receiving chamber 13 through the gap.

[0167] Thus, by forming a gap between the sidewall of the mounting groove 121 and the sidewall of the battery cell 32, the high-pressure gas ejected from the battery cell 32 can flow from the gap into the receiving chamber 13 to achieve the purpose of depressurization.

[0168] Furthermore, by utilizing the gap between the sidewall of the mounting groove 121 and the sidewall of the battery cell 32 to achieve communication between the pressure relief groove 121b and the receiving chamber 13, this design eliminates the need for additional processing of complex pressure relief channels or communication structures, reducing the complexity of the manufacturing process, reducing production costs, and improving production efficiency.

[0169] Specifically, the diameter of the battery cell 32 can be adapted to the diameter of the mounting groove 121, so that the side wall of the mounting groove 121 and the side wall of the battery cell 32 form a gap, and the pressure relief groove 121b communicates with the receiving chamber 13 through the gap, so that the high pressure gas released from the battery cell 32 into the pressure relief groove 121b can flow into the receiving chamber 13 through the gap.

[0170] Please refer to Figure 12In some embodiments, the support structure 121a is arc-shaped, the battery cell 32 is a cylindrical battery, and the support structure 121a abuts against the edge of the second end 321 of the battery cell 32.

[0171] Thus, the shape of the support structure 121a matches that of the battery cell 32, which enables the support structure 121a to effectively support the battery cell 32 and prevent the battery cell 32 from shaking.

[0172] Please refer to Figure 12 In some embodiments, the support structure 121a is a rib provided in the mounting groove 121, and the rib is connected to the side wall of the mounting groove 121.

[0173] Thus, the protruding ribs create a certain distance between the second end 321 of the battery cell 32 and the bottom of the mounting groove 121, thereby ensuring the formation of the pressure relief groove 121b and its communication with the receiving chamber 13. Furthermore, the protruding 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, thus improving the overall structural stability of the battery module 30.

[0174] Specifically, the ribs can take 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 attached to the side wall of the battery cell 32 and positioned near the mounting groove 121. Because the ribs directly abut against the second end 321 of the battery cell 32, if the second end 321 is subjected to large pressure and collapses, it may cause a short circuit in the battery cell 32. However, the arc-shaped ribs are positioned near the mounting groove 121, and they abut against the edge of the second end 321 of the battery cell 32. The pressure is transmitted more to the side wall of the battery cell 32 rather than the end, which can greatly reduce the risk of short circuit in the battery cell 32.

[0175] The raised rib can be integrally formed with the sidewall of the mounting groove 121, which reduces connection gaps and weak points, thereby improving the structural rigidity of the raised rib and its supporting performance. The raised rib can be a continuous structure, which facilitates manufacturing and reduces manufacturing costs.

[0176] Please refer to Figure 12 and Figure 14 In some embodiments, there are two ribs, which are arranged opposite each other and form a pressure relief groove 121b.

[0177] Thus, the two protruding ribs are arranged opposite each other to form a pressure relief groove 121b. This design achieves effective support and pressure relief for the battery cell 32 without increasing the space occupied. The two protruding ribs can evenly distribute the pressure on the second end 321 of the battery cell 32, preventing the battery cell 32 from tilting or shaking in the mounting groove 121, further improving the overall structural stability of the battery module 30. Especially when the energy storage power supply 100 is subjected to vibration or drop, it better protects the battery cell 32 and reduces the risk of damage to the battery cell 32.

[0178] Specifically, the two convex ribs can be symmetrical, which can provide more uniform support for the battery cell 32.

[0179] Please refer to Figure 12 and Figure 14 In some embodiments, the battery cell 32 is a cylindrical battery, and the rib includes a support portion 121e and a connecting portion 121f. The support portion 121e is arranged in an arc shape in the mounting groove 121. The connecting portion 121f passes through two mounting grooves 121 and is connected to two support portions 121e at both ends. Two ribs pass through multiple mounting grooves 121 and form a guide channel 121d. The guide channel 121d communicates with the receiving chamber 13, and the pressure relief structure 32a faces the guide channel 121d.

[0180] Thus, when any single battery cell 32 experiences thermal runaway, the guiding channel 121d can guide the high-pressure gas and quickly discharge it, reducing the accumulation and propagation of high-pressure gas within the battery module 30. This design helps suppress the spread of thermal runaway among multiple battery cells 32, protecting other battery cells 32 from the effects of thermal runaway and further enhancing the safety of the energy storage power supply 100. The arc-shaped support portion 121e can stably support the cylindrical battery and prevent it from shaking. The connecting portion 121f passes through the two mounting slots 121 and connects to the two support portions 121e at both ends. This design not only enhances the stability of the battery cell 32 within a single mounting slot 121, but also connects adjacent support portions 121e together through the connecting portion 121f, improving the structural stability of the entire battery module 30.

[0181] Specifically, the inner walls of the two convex ribs can form a guide channel 121d. The guide channel 121d can have an open opening. The open opening can communicate with the receiving 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 disposed 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 into the receiving chamber 13 under the guidance of the guide channel 121d.

[0182] The connecting part 121f and the supporting part 121e can be integrally formed, which can reduce connection gaps and weak points, thereby enhancing the overall structural rigidity of the connecting part 121f and the supporting part 121e.

[0183] 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.

[0184] Thus, the arrangement of the first substrate 111, the second substrate 122, the panel 112, and the second side panel 123 makes it easy to install the first housing 11 and the second housing 12, thereby improving assembly efficiency.

[0185] 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. The battery module 30 includes an electrical connector 33. The electrical connector 33 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. The second end 321 is embedded in the mounting groove 121.

[0186] Thus, through the cooperation of the first electrode 3200, the second electrode 3201, and the electrical connector 33, electrical connections between multiple battery cells 32 can be quickly achieved, and multiple battery cells 32 can be 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, and together with the fixation of the first electrode 3200, the second electrode 3201, and the electrical connector 33, the stability of the battery cell 32 under vibration or impact environments is ensured, reducing the risk of displacement or loosening.

[0187] Specifically, the 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 the battery module 30, providing the required voltage and capacity. The battery cell 32 can be of various types, such as lithium-ion batteries, lead-acid batteries, or nickel-metal hydride batteries. The battery cell 32 can be designed in different shapes and sizes, such as cylindrical, square, or pouch cells.

[0188] 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 current collector and a positive active material layer. The material of the positive current collector can be aluminum, and the positive active material layer can include positive active materials such as lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide. The negative electrode can include a negative current collector and a negative active material layer. The material of the negative current collector can be copper, and the negative active material layer can include negative active materials such as carbon or silicon.

[0189] Electrical connector 33 is an electrical connection component used to connect adjacent battery cells 32. By mating with the electrodes of different battery cells 32, electrical connector 33 achieves electrical connection between adjacent battery cells 32, ensuring stable current transmission. Electrical connector 33 can take various forms, such as connecting pieces, connecting wires, or solder joints. The material of electrical connector 33 can be a highly conductive metal, such as copper or aluminum. Electrical connector 33 can be designed with protective functions, such as an insulating layer and anti-loosening structures.

[0190] 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 a first direction v of the receiving chamber 13. The battery module 30 forms a first high region 34 and a first low region 35 with a height difference in the first direction v. The circuit board module 20 forms a second high region 23 and a second low region 24 with a height difference in the first direction v. The first high region 34 and the second low region 24, and the first low region 35 and the second high region 23, partially overlap in the first direction v. The first high region 34 and the second high region 23 partially overlap in the second direction h. The second direction h is perpendicular to the first direction v.

[0191] Thus, the first low area 35 of the battery module 30 can provide clearance 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 clearance 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 housing chamber 13, reduces the overall volume, and improves the portability of the energy storage power supply 100.

[0192] Specifically, for a cuboid energy storage power supply 100, the first direction v can be the height direction of the energy storage power supply 100, and the second direction h can be the length direction of the energy storage power supply 100.

[0193] Height difference refers to the different height areas of the battery module 30 or the circuit board module 20 in the first direction v. Overlap refers to the projected areas of the battery module 30 and the circuit board module 20 overlapping each other in the first direction v or the second direction h.

[0194] Please refer to Figure 17 and Figure 18 In some embodiments, the first circuit board 21 forms a second high region 23 and a second low region 24.

[0195] Thus, by dividing the circuit board module 20 into a first circuit board 21 and a second circuit board 22, and forming a second high area 23 and a second low area 24 on the first circuit board 21, the space of the accommodating chamber 13 can be utilized more flexibly. The height difference design of the first circuit board 21 provides more clearance space for the second circuit board 22 or other components, thereby further optimizing the overall layout and improving space utilization.

[0196] Please refer to Figure 16 and Figure 18 In some embodiments, the first housing 11 and the second housing 12 are arranged along the height direction, the first housing 11 is disposed on the top of the second housing 12, the circuit board module 20 includes a board body 211 and a functional element 20b disposed on the board body 211, the board body 211 is disposed on the top of the first housing 11, and the functional element 20b is disposed from the board body 211 toward the battery module 30.

[0197] In this way, this layout can shorten the electrical connection distance between the functional components 20b on the circuit board module 20 and the battery module 30, reduce the length and complexity of the connection lines, and reduce signal transmission loss and electromagnetic interference.

[0198] Specifically, functional element 20b may include sensors, controllers, communication modules, etc. Functional element 20b can realize various functions of circuit board module 20, such as monitoring battery status and controlling the charging and discharging process. Functional element 20b may include various electrical components with different heights and functions. For example, functional element 20b may include a first heating element 230 and a second heating element 240.

[0199] Please refer to Figure 16 and Figure 18 In some embodiments, the board body 211 is fixed to the housing 10, and the functional element 20b is disposed along the first direction v and toward the battery module 30, so that the circuit board module 20 forms a second high region 23 and a second low region 24. In this way, by optimizing the layout of the functional element 20b, the circuit board module 20 can form a second high region 23 and a second low region 24, thereby being able to form an interleaved arrangement with the first high region 34 and the first low region 35 of the battery module 30, so as to improve the space utilization of the receiving chamber 13.

[0200] Please refer to Figure 18 In some embodiments, the second high region 23 has a first heating element 230 and the second low region 24 has a second heating element 240, wherein the heat output of the first heating element 230 is greater than the heat output of the second heating element 240.

[0201] Thus, by placing the first heating element 230, which generates a large amount of heat, in the second high zone 23, the relatively open space of the second high zone 23 can be utilized or additional heat dissipation structures can be designed to improve heat dissipation efficiency. Meanwhile, the second heating element 240, which generates less heat, is placed in the second low zone 24. Even though the space in the second low zone 24 is relatively compact, its performance will not be affected by poor heat dissipation.

[0202] Specifically, the first heat-generating element 230 can be a component on the circuit board that generates a large amount of heat, such as a MOSFET, inductor, transformer, and heat sink. The second heat-generating element 240 can be a component on the circuit board that generates less heat, such as a connector or capacitor.

[0203] In other embodiments, the taller components are placed in the second high region 23, and the shorter components are placed in the second low region 24.

[0204] 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 region 23 away from the second low region 24 and forms at least part of the second high region 23. The cooling fan 212 forms an airflow that dissipates heat through the second low region 24.

[0205] Thus, the position of the cooling fan 212 allows it to simultaneously dissipate heat from the second high zone 23 and the second low zone 24, with better heat dissipation from the second high zone 23, effectively reducing the temperature of the first heat-generating element 230, which generates a large amount of heat. This active cooling 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 heat-generating element 230 operates within a safe temperature range.

[0206] In addition, the cooling fan 212 forms at least part of the second high zone 23, which allows the cooling fan 212 to be equipped with a fan with greater airflow, thereby providing better heat dissipation.

[0207] Specifically, the cooling fan 212 is an active cooling device that generates airflow through rotation to remove heat. The cooling fan 212 can be mounted on the plate 211 by bolts or other mechanical connections. The cooling fan 212 can either draw in or exhaust air. When configured to blow air, the cooling fan 212 can create a cooling airflow toward the second low zone 24; when configured to exhaust air, the cooling fan 212 can create a cooling airflow toward the second high zone 23.

[0208] 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 forms an airflow channel from the cooling fan 212 to the second high region 23, and the duct element 213 forms a portion of the second low region 24.

[0209] Thus, the airflow channel formed by the air duct element 213 can guide the airflow generated by the cooling fan 212 to flow more directly to the heat-generating element in the second high zone 23, thereby improving heat dissipation efficiency. This directional heat dissipation design can ensure that the first heat-generating element 230 located in the second high zone 23 is cooled more effectively, especially under high-load operating conditions.

[0210] Specifically, the air duct element 213 is a structural component used to guide airflow. The inlet of the air duct element 213 is near the second high zone 23, and the outlet of the air duct element 213 is near the air inlet 1100 of the cooling fan 212. This allows airflow to enter the air duct element 213 through the second low zone 24 under the suction of the cooling fan 212, flow through the second high zone 23, and then be discharged by the cooling fan 212. The second low zone 24 has relatively low heat generation, so the airflow temperature will not be excessively heated after flowing through it. The relatively low airflow temperature when flowing into the second high zone 23 is more conducive to removing heat from the second high zone 23. The air duct element 213 can be made of plastic or metal. The air duct element 213 can be an air guide shroud, an air duct, or other similar structures. For example, the air duct element 213 can be an air duct made of plastic material, with the inlet of the air duct near the air outlet 1101 of the cooling fan 212 and the outlet near the second high zone 23.

[0211] 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 region 34 and a first low region 35.

[0212] Thus, by stacking some of the battery cells 32 along the first direction v, a first high region 34 and a first low region 35 with a height difference can be formed, thereby providing clearance space for the circuit board module 20 or other components. This design significantly improves the space utilization of the housing chamber 13, making the overall structure of the energy storage power supply 100 more compact.

[0213] Specifically, the bracket 31 can be fixedly installed on the housing 10 by means of bolt connection, snap connection or plug connection. 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, so that the battery cells 32 in different areas of the battery module 30 have a height difference to form the first high area 34 and the first low area 35.

[0214] Please refer to Figure 17 , Figure 19 and Figure 20 In some embodiments, the energy storage power supply 100 includes a heat insulation component 40 disposed between the battery module 30 and the circuit board module 20, the heat insulation component 40 covering the battery module 30.

[0215] In this way, the heat insulation component 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 performance degradation or shortened lifespan of the circuit board module 20 due to overheating.

[0216] Specifically, the thermal insulation element 40 is a component used to reduce heat transfer and can be made of a low thermal conductivity material, such as ceramic fiber, asbestos, or aerogel. The thermal insulation element 40 can be designed as a plate, sheet, or other suitable shape.

[0217] Covering the battery module 30 means that the heat insulation component 40 completely covers the battery module 30, or in other words, the orthogonal projection of the battery module 30 onto the heat insulation component 40 is located inside the heat insulation component 40.

[0218] 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.

[0219] Thus, the shielding component 25, positioned on the side of the circuit board module 20 opposite to the battery module 30, effectively guides and dissipates the heat generated by the 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 the circuit board module 20 under long-term operation or high-load conditions. Furthermore, by reducing electromagnetic interference, the shielding component 25 helps improve the signal integrity and reliability of the circuit board module 20, ensuring the accuracy and stability of data transmission.

[0220] Specifically, the shield 25 is a component used to dissipate heat and can be made of a high thermal conductivity material, such as aluminum, copper, or graphite. The shield 25 can take various forms, such as heat sinks, heat pipes, fans, or thermal paste. The heat dissipation method of the shield 25 can be passive or active. The shield 25 can achieve its heat dissipation function in various ways, such as increasing surface area, using thermally conductive materials, and designing airflow channels.

[0221] The shielding component 25 can be made of electromagnetic shielding material (such as a metal plate or conductive coating), which can effectively shield the electromagnetic interference generated by the circuit board module 20, preventing it from affecting other surrounding electronic devices. It can also prevent external electromagnetic interference from entering the circuit board module 20, ensuring its normal operation. When both heat dissipation and electromagnetic interference shielding are required, the shielding component 25 can be made of aluminum, copper, or similar materials.

[0222] In some embodiments, the shield 25 abuts against the housing 10.

[0223] In this way, the shielding member 25 abuts against the housing 10, which can directly conduct the heat generated by the circuit board module 20 to the housing 10, and then dissipate it to the external environment through the housing 10. This design significantly improves heat dissipation efficiency, especially under high-load operating conditions, ensuring the stable operation of the circuit board module 20.

[0224] 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. A ventilation section 110a is provided on the housing 10, and the ventilation section 110a forms a vent 110; the battery module 30 is disposed inside the housing 10; the support mesh 50 is disposed on the inner side of the housing 10 and is attached to the ventilation section 110a to support the ventilation section 110a.

[0225] Thus, by providing a support mesh 50 on the inner side of the housing 10 and attaching it to the ventilation section 110a to support it, the structural strength of the ventilation section 110a can be significantly enhanced. The support mesh 50 not only prevents foreign objects from entering the housing 10 through the ventilation opening 110, but also reduces the risk of breakage of the ventilation section 110a during drops or vibrations, thereby improving the safety of the ventilation section 110a. Furthermore, the design of the support mesh 50 does not affect the heat dissipation function of the ventilation opening 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.

[0226] Specifically, the support mesh 50 can be a protective structure disposed on the inner side of the housing 10 to cover the ventilation opening 110. The support mesh 50 can be made of metal wire mesh, plastic mesh, or other materials with sufficient strength and breathability. The support mesh 50 can be directly disposed on the inner side of the housing 10 by means of bonding or welding, or it can be disposed on the inner side of the housing 10 by other mounting structures. For example, the support mesh 50 can be attached to the ventilation section 110a with sealant.

[0227] The number of support nets 50 can correspond one-to-one with the number of vents 110. For example, for a single vent 110, one support net 50 is configured. For multiple vents 110, multiple support nets 50 are configured in equal numbers.

[0228] Please refer to Figure 24 In some embodiments, the first housing 11 is formed with a vent 110, and the support mesh 50 is disposed on the inner side of the first housing 11.

[0229] Thus, when the ventilation area 110 or the support mesh 50 of the housing 10 is damaged, since the first housing 11 and the second housing 12 are detachably connected, the user can replace the damaged first housing 11 or the second housing 12 individually 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.

[0230] Please refer to Figure 23 and Figure 24 In some embodiments, the inner side of the first housing 11 is provided with a limiting strip 113, and the limiting strip 113 and the inner side of the first housing 11 together define a second limiting groove 114, and the support mesh 50 is at least partially disposed in the second limiting groove 114.

[0231] Thus, by fixing the support net 50 with the second limiting groove 114, it is possible to effectively prevent the support net 50 from shifting or shaking within the housing 10. Especially when the energy storage power supply 100 is subjected to drops, vibrations, or impacts, it ensures that the support net 50 always covers the ventilation opening 110, maintaining the protective function of the support net 50. In addition, the limiting strip 113 can also be used as a guide structure during the installation of the support net 50, which facilitates the rapid installation of the support net 50.

[0232] Specifically, the limiting strip 113 can be a protrusion extending from the inner side of the first outer shell 11. There can be multiple limiting strips 113, such as two, three, four, or even more. The limiting strip 113 and the first outer shell 11 can be integrally molded, which reduces connection gaps and weak points, thereby enhancing the structural rigidity of the limiting strip 113. Alternatively, the limiting strip 113 and the first outer shell 11 can be separately molded, which facilitates replacement of the limiting strip 113 and extends its service life.

[0233] Please refer to Figure 23 and Figure 24 In some embodiments, there are two limiting strips 113, which are spaced apart and extend along the first outer shell 11 toward the second outer shell 12. The support net 50 is at least partially disposed between the two limiting strips 113.

[0234] Thus, by using two spaced limit bars 113, the installation position of the support net 50 can be more precisely defined, ensuring that the support net 50 will not shift or tilt during installation.

[0235] The spacing and extension direction of the two limiting strips 113 make the installation of the support net 50 simpler and faster. During installation, simply align the support net 50 with the gap between the two limiting strips 113 and insert it; disassembly is similarly simple, just remove the support net 50 from between the two limiting strips 113. This design not only improves the efficiency of installation and disassembly but also reduces the risk of damage to the support net 50 due to improper installation.

[0236] 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.

[0237] 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 outer shell 11.

[0238] Thus, the design of the mounting part 52 allows the support net 50 to adapt to different housing 10 structures. Even if the size or shape of the second limiting groove 114 of the housing 10 changes, the support net 50 can still be used normally as long as the mounting part 52 can be fixed on the first housing 11. This design improves the versatility and adaptability of the support net 50 and reduces production costs.

[0239] 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 disposed in the second limiting groove 114 to ensure that it fits tightly against the ventilation opening 110, while the mounting portion 52 is directly fixed to the first outer shell 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.

[0240] Specifically, the mesh portion 51 is the main part of the support mesh 50, and is typically composed of a mesh structure used to cover the vent 110. The mesh portion 51 allows airflow while preventing foreign objects from entering the housing 10 through the vent 110. The mesh portion 51 can be designed in various shapes and sizes, such as rectangular mesh, circular mesh, or irregularly shaped mesh, to accommodate different vent 110 designs.

[0241] Mounting part 52 is another part of the support net 50, used to fix the support net 50 to the first housing 11. Mounting part 52 can be installed on the first housing 11 by bolting, gluing, welding or other means. The number of mounting parts 52 can be one or more, such as two, three, four or more.

[0242] Please refer to Figure 22 , Figure 23 and Figure 24 In some embodiments, the mesh portion 51 is provided with mesh holes 51a, and the mesh holes 51a are provided corresponding to the vents 110.

[0243] In this way, the mesh part 51 can be prevented from covering the vent 110, thereby avoiding affecting the airflow at the vent 110.

[0244] Specifically, the mesh 51a can be designed in various shapes and sizes, such as regular shapes like round or 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.

[0245] Please refer to Figure 23 and Figure 24 In some embodiments, the first housing 11 is provided with a stud 115 that is mounted and connected to the second housing 12, and the mounting part 52 is sleeved on the stud 115.

[0246] In this way, by fitting the mounting part 52 onto the stud 115 instead of using connecting parts such as bolts or screws to connect the mounting part 52 and the stud 115, the use of connecting parts can be reduced, thereby reducing the manufacturing cost of the energy storage power supply 100.

[0247] Specifically, the stud 115 can be a hollow cylindrical structure with threaded holes. The stud 115 is a structural component mounted on the first housing 11 for connection and installation with the second housing 12, and serves as support for the mounting portion 52 of the support mesh 50. The shape and size of the stud 115 can be designed according to 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 it can be part of the first housing 11.

[0248] The fit can be tight or loose, depending on the installation requirements. Fitting can be achieved through interference fit, clearance fit, or transition fit.

[0249] The mounting portion 52 may be provided with a hole for engaging with the stud 115, and the wall surface of the hole on 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 connecting components such as bolts or screws. For example, the connecting component is a bolt. During the connection process of the first housing 11 and the second housing 12, the bolt can be used to engage with the threaded hole on the stud 115, thereby allowing the head of the bolt to limit the mounting portion 52, thus completing the fixation of the mounting portion 52.

[0250] Please refer to Figure 23 and Figure 24 In some embodiments, the first housing 11 includes a first substrate 111 and a first side plate 116 connected to the first substrate 111. The first side plate 116 forms a vent 110. The stud 115 includes a first stud 1150 and a second stud 1151. The first stud 1150 is disposed on the first substrate 111, and the second stud 1151 is disposed on the first side plate 116. The position height of the first stud 1150 is higher than that of the second stud 1151. There are two mounting parts 52, one of which is sleeved on the first stud 1150 and the other mounting part 52 is sleeved on the second stud 1151.

[0251] Thus, if the first stud 1150 and the second stud 1151 are set at the same height, one side of the support net 50 is prone to forming a free end, thus tending to detach from the inner surface of the housing 10. By setting the first stud 1150 and the second stud 1151 at different heights, the support net 50 can be fixed more stably, thereby preventing the support net 50 from detaching from the inner surface of the housing 10 under external force, and thus preventing the support net 50 from malfunctioning.

[0252] Specifically, for the cuboid 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 plate 116, and the first substrate 111 is basically parallel to the horizontal plane. At this time, the position height of the first stud 1150 and the position height of the second stud 1151 both refer to the height of the first stud 1150 and the second stud 1151 relative to the horizontal plane.

[0253] In some embodiments, the cooling fan 212 generates airflow that flows through the vent 110. Thus, the airflow generated by the cooling fan 212 can exit the interior of the housing 10 from the vent 110, thereby accelerating airflow between the inside and outside of the housing 10 and improving heat dissipation efficiency.

[0254] 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 shield 25. The housing 10 has an opening slot 14 located within the receiving 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, and the handle 61 rotates relative to the housing 10 via the rotating shaft 62. One end of the rotating shaft 62 extends into the opening slot 14. The fixing member 63 is located on the rotating shaft 62 and abuts against the groove wall of the opening slot 14 to restrict the rotating shaft 62 from moving relative to the housing 10 along its own axial direction; the shield 25 is disposed within the receiving chamber 13 and closes the opening of the opening slot 14.

[0255] Thus, by setting the fixing member 63 in the opening slot 14 and setting the blocking member 25 to close the opening slot 14, the fixing member 63 is prevented from accidentally coming out, protecting the components inside the energy storage power supply 100 and improving the safety of the energy storage power supply 100.

[0256] Specifically, the number of 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 requirements, such as a regular shape like a circle or square, or an irregular shape.

[0257] The handle assembly 60 facilitates user carrying of the energy storage power supply 100, while the pivot 62 and fixing member 63 ensure the stability and reliability of the handle 61. The handle 61 is the part the user grips and can be made of a sturdy and durable material, such as plastic or rubber. The handle 61 facilitates user carrying of the energy storage power supply 100.

[0258] The pivot 62 is a component that connects the handle 61 and the housing 10. The shape and material of the pivot 62 can be selected according to requirements; for example, the pivot 62 can be a cylindrical metal or plastic shaft.

[0259] The fastener 63 is a component used to fix the rotating shaft 62, such as a retaining ring 630 or a nut. The fastener 63 can be a ring-shaped part made of metal or plastic. The fastener 63 can directly abut against the groove wall of the opening groove 14, or indirectly. For example, a friction pad can be provided between the fastener 63 and the groove wall of the opening groove 14, and the friction pad can abut against the two adjacent sides of the fastener 63 and the groove wall of the opening groove 14. In this way, the friction pad can avoid friction between the fastener 63 and the groove wall of the opening groove 14, thereby improving the service life of the fastener 63.

[0260] The shield 25 is a component used to close the opening of the slot 14, and can be a plate, sheet, mesh, or other shape structure made of materials such as metal, plastic, or rubber. The shield 25 is used to prevent the fastener 63 from falling out and to protect the components inside the opening slot 14 from interference by external foreign objects.

[0261] Please refer to Figure 28 and Figure 29 In some embodiments, the shielding member 25 is disposed on the circuit board module 20.

[0262] Thus, the shielding component 25 is installed on the circuit board module 20, further enhancing the protection of the circuit board module 20. Since the circuit board module 20 is the core component of the energy storage power supply 100, it is more susceptible to external interference. The shielding component 25 can effectively prevent external factors from affecting the circuit board module 20 and improve the reliability of the circuit board module 20.

[0263] Specifically, the shielding member 25 is installed on the circuit board module 20 by mechanical fixing, adhesive bonding or other means. The shielding member 25 can be directly connected to the circuit board module 20, for example, it can be fixed to the circuit board module 20 by screws, clips, glue or other means; or it can be connected to the inner wall of the housing 10 to be suspended on the circuit board module 20.

[0264] Please refer to Figure 27 In some embodiments, the fastener 63 includes a retaining ring 630 having a circumferentially oriented locking groove 631, which is engaged with the rotating shaft 62.

[0265] Thus, the fastener 63 adopts a retaining ring 630 with a circumferential bayonet 631. The retaining ring 630 is locked on the rotating shaft 62, which can effectively restrict the axial movement of the rotating shaft 62, thereby improving the stability of the fastener 63 and preventing it from loosening or falling off during use.

[0266] Specifically, the retaining ring 630, through its locking slot 631, engages with the rotating shaft 62 to achieve axial fixation of the shaft 62. Due to the presence of the locking slot 631, the retaining ring 630 can elastically deform, allowing for easy installation and removal. The retaining ring 630 can be designed in various types, such as a shaft retaining ring or a hole retaining ring, to adapt to different installation positions and fixing requirements.

[0267] The bayonet 631 can be one or more grooves. The bayonet 631 is used to mate with a corresponding structure on the rotating shaft 62, locking into the groove of the rotating shaft 62 through elastic deformation to achieve fixation. The bayonet 631 can be designed to be uniformly or non-uniformly distributed to accommodate different diameters of the rotating shaft 62 and fixation requirements. The shape of the bayonet 631 can be circular, square, or other suitable shapes.

[0268] Please refer to Figure 29 In some embodiments, the housing 10 is provided with a transition hole 15, in which the rotating shaft 62 is inserted. The handle assembly 60 also includes a damping member 64 sleeved on the rotating shaft 62. The damping member 64 is located in the transition hole 15 and is flush with the wall of the transition hole 15.

[0269] Thus, the damping element 64 provides a certain amount of resistance, preventing the handle 61 from becoming too loose when rotated, thereby controlling the rotation speed and force of the handle 61 and improving the operational stability of the energy storage power supply 100. Furthermore, the resistance provided by the damping element 64 gives the handle 61 a certain damping feel when rotated, enhancing the user experience when operating the handle 61 and making operation smoother and more controllable.

[0270] Specifically, the adapter hole 15 is a hole on the housing 10 for inserting the rotating shaft 62. The adapter hole 15 provides a mounting position for the rotating shaft 62 and, through its cooperation with the damping element 64, ensures the stability of the rotating shaft 62 and the damping effect of its 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 element 64 to ensure optimal fit. The adapter hole 15 can be designed as circular, elliptical, or other suitable shapes.

[0271] The damping element 64 is a component used to provide resistance. The damping element 64 can be made of rubber, plastic, or other materials with damping properties. Through contact with the wall of the adapter hole 15, the damping element 64 provides appropriate resistance, controlling the rotation speed and force of the handle 61, and improving operational stability and precision. The damping element 64 can be designed in various types, such as damping rings or damping sleeves, to adapt to different shafts 62 and adapter holes 15. The material and shape of the damping element 64 can be selected as needed to achieve different damping effects. The damping element 64 can be fixed to the shaft 62 by interference fit, bonding, or other methods to ensure that it will not loosen or fall off during use.

[0272] Please refer to Figure 30 , Figure 31 and Figure 32 In some embodiments, the handle 61 is provided with a pivot hole 610. One of the holes 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. The stop protrusion 611 is engaged in the stop groove 620 so that the handle 61 and the rotating shaft 62 rotate synchronously.

[0273] Thus, by providing a stop groove 620 and a stop protrusion 611 between the pivot hole 610 of the handle 61 and the circumferential surface of the rotating shaft 62, synchronous rotation between the handle 61 and the rotating shaft 62 is ensured. This design effectively prevents relative slippage between the handle 61 and the rotating shaft 62, improving operational reliability.

[0274] Specifically, the pivot hole 610 provides an installation position for the rotating shaft 62 and, through its cooperation with the rotating shaft 62, enables the handle 61 to rotate. The shape and size of the pivot hole 610 can be adjusted according to the specific design of the rotating shaft 62 to ensure optimal fit. The pivot hole 610 can be designed as circular, elliptical, or other suitable shapes.

[0275] The stop groove 620 is a recess on the wall of the pivot hole 610 or on the circumference of the shaft 62. The stop groove 620 engages with the stop protrusion 611 to prevent relative slippage between the handle 61 and the shaft 62, ensuring synchronous rotation. The stop groove 620 can be designed in various shapes, such as circular, square, or dovetail, to suit different fixing requirements. The depth and width of the stop groove 620 can be adjusted according to actual needs.

[0276] 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 mates with the stop groove 620 to prevent relative sliding between the handle 61 and the rotating shaft 62, ensuring synchronous rotation. The stop protrusion 611 can be designed in various shapes, such as round, square, or dovetail, to suit different fixing requirements. The height and width of the stop protrusion 611 can be adjusted according to actual needs.

[0277] Please refer to Figure 25 and Figure 27 In some embodiments, a handle 61 is provided on a first housing 11, and the first housing 11 is provided with an opening slot 14.

[0278] Thus, during the assembly process, the handle 61 and the first housing 11 can be assembled first, and then the whole assembly can be connected to the second housing 12. This step-by-step assembly method can improve assembly efficiency and reduce assembly errors. Furthermore, both the handle 61 and the opening slot 14 are located on the first housing 11, which can reduce the manufacturing complexity of the handle assembly 60 and improve manufacturing efficiency.

[0279] Please refer to Figure 25 and Figure 27 In some embodiments, the first side plate 116 is connected to the second outer shell 12, the inner surface of the first substrate 111 is provided with a surrounding wall 1110, the surrounding wall 1110 forms an opening groove 14, and the handle 61 is disposed on the first substrate 111.

[0280] Thus, the enclosure 1110 not only provides structural support for the opening slot 14, but also plays a certain protective role, preventing external objects from directly impacting the rotating shaft 62 and the fixing member 63 in the opening slot 14, thereby protecting the components located inside the opening slot 14.

[0281] Specifically, the enclosure 1110 can be mechanically fixed to the inner surface of the first substrate 111, such as by bolting, bonding or snapping. The enclosure 1110 and the first substrate 111 can also be integrally formed, which can reduce connection gaps and weak points, thereby enhancing the structural rigidity of the enclosure 1110.

[0282] The handle 61 can be mounted on the first substrate 111 via the pivot 62, or in other words, the handle 61 can rotate relative to the first substrate 111 via the pivot 62.

[0283] Please refer to Figure 30 In some embodiments, the rotating shaft 62 is provided with at least one weight-reducing groove 621.

[0284] Thus, by providing at least one weight-reducing groove 621 on the rotating shaft 62, the weight of the rotating shaft 62 can be effectively reduced, thereby reducing the weight of the entire energy storage power supply 100 and improving the portability of the energy storage power supply 100.

[0285] Specifically, the weight-reduction slot 621 can be designed in various shapes and sizes, such as rectangular, semi-circular, trapezoidal, etc., to adapt to different weight-reduction and heat dissipation requirements. The depth and width of the weight-reduction slot 621 can be adjusted according to actual needs. The number of weight-reduction slots 621 can be one, two, three, or even more.

[0286] The weight-reducing groove 621 can be formed by machining, such as turning or drilling. The weight-reducing groove 621 can also be formed by molding. 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.

[0287] 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 a mounting hole 16; the sliding button 80 is slidably mounted in the mounting hole 16; the elastic pressing member 90 is disposed in the housing 10 and presses against the sliding button 80.

[0288] Thus, the presence of the elastic pressure member 90 provides a uniform elastic force, ensuring that the sliding button 80 is always subjected to stable pressure during operation. This design effectively reduces the poor tactile feedback of the sliding button 80 during operation, making the tossing force more uniform. Consequently, users will not experience noticeable tactile differences or uneven resistance during operation, reducing the risk of misoperation due to uneven force and improving the user's tactile experience.

[0289] Specifically, the mounting hole 16 provides a mounting position for the sliding button 80 and restricts the movement trajectory of the sliding button 80, allowing the sliding button 80 to slide within the housing 10. The shape and size of the mounting hole 16 can be designed according to the shape and size of the sliding button 80; for example, it can be a straight hole, a curved hole, or other types of holes. The surface of the mounting hole 16 can be smoothed to reduce the friction of the sliding button 80 during sliding.

[0290] The sliding button 80 is a sliding mechanical component used to control the switching or function transition of the energy storage power supply 100. The sliding button 80 can slide along the path defined by the mounting hole 16. The sliding button 80 can be made of plastic or metal, etc., to meet different usage requirements.

[0291] The resilient pressure-absorbing component 90 is a flexible part used to provide stable pressure resistance. The resilient pressure-absorbing component 90 can be made of a variety of elastic materials, such as plastic, rubber, or silicone.

[0292] Please refer to Figure 35 In some embodiments, the elastic pressing member 90 includes a body 91 and an elastic arm 92 disposed on the body 91. The body 91 is mounted on the housing 10, and the elastic arm 92 presses against the sliding button 80.

[0293] Thus, the elastic pressing component 90 is composed of two parts: a body 91 and an elastic arm 92. The body 91 is mounted on the housing 10, and 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, thereby further improving the uniformity of the force applied during the sliding button 80's operation. The elastic deformation of the elastic arm 92 can dynamically adjust the pressing force, reducing the possibility of poor tactile feedback when operating the sliding button 80 due to structural gaps or changes in friction.

[0294] Specifically, the body 91 and the elastic arm 92 can be connected by mechanical fixing methods, such as bonding, welding, or snap-fitting. The body 91 and the elastic arm 92 can also be a single molded structure, which reduces connection gaps and weak points, thereby improving the overall structural rigidity of the elastic pressure member 90. The body 91 can be installed on the housing 10 by bonding, welding, or threaded connection.

[0295] The elastic arm 92 can be made of various elastic materials, such as spring steel, rubber, and silicone. The shape and size of the elastic arm 92 can be designed according to actual needs; for example, it can be corrugated, spring-shaped, or sheet-shaped.

[0296] "Pressing" refers to the state in which the elastic arm 92 applies pressure to the sliding button 80. Through pressing, the elastic arm 92 can provide uniform pressing force to the sliding button 80, ensuring a smooth feel when the sliding button 80 is tossed, reducing the occurrence of poor feel when operating the sliding button 80, thereby improving the user experience.

[0297] Please refer to Figure 35 In some embodiments, the body 91 is frame-shaped and has a hollow hole 910, and the two ends of the elastic arm 92 are connected to the hole wall of the hollow hole 910.

[0298] Thus, the body 91 of the elastic pressing member 90 is frame-shaped and has a hollow hole 910, with both ends of the elastic arm 92 connected to the wall of the hollow hole 910. This design makes the deformation of the elastic arm 92 more concentrated and stable under force, thereby further optimizing the uniformity of force when the sliding button 80 is toggled. The presence of the hollow hole 910 makes the deformation of the elastic arm 92 more uniform, reduces local stress concentration, and further improves the poor feel when operating the sliding button 80.

[0299] Specifically, the body 91 is a component with a frame structure, which can be a rectangular, square or other polygonal ring structure.

[0300] The perforated hole 910 is one or more openings on the body 91, used to connect the elastic arm 92 and optimize deformation distribution. The presence of the perforated hole 910 reduces material usage and weight, while allowing both ends of the elastic arm 92 to connect to the hole wall, making the deformation of the elastic arm 92 more concentrated and uniform under stress. The shape and size of the perforated hole 910 can be designed according to actual needs, for example, it can be circular, square, elliptical, etc. The number of perforated holes 910 can also be adjusted as needed, for example, there can be one or more, such as two, three, four, or even more.

[0301] The two ends of the elastic arm 92 can be connected to the wall of the hollow hole 910 by bonding, threading, plugging or other means.

[0302] Please refer to Figure 35 In some embodiments, the elastic arm 92 is corrugated and has a trough 920, which presses against the sliding button 80.

[0303] Thus, the corrugated structure makes the deformation of the elastic arm 92 more uniform when subjected to force, and the troughs 920 can provide more stable resistance, thereby further improving the uniformity of force when the sliding button 80 is toggled. This design can effectively reduce the poor feel when operating the sliding button 80, making the toggling force more uniform and significantly improving the user experience.

[0304] Specifically, the trough 920 is the lowest point of the corrugated elastic arm 92, located in the recess of the corrugations. The trough 920 directly presses against the sliding 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 is more concentrated and stable under force, thereby reducing the poor feel when operating the sliding button 80 and improving the user's operating experience.

[0305] Please refer to Figure 35 In some embodiments, the inner surface of the housing 10 is provided with a support platform 17, and the body 91 abuts against the support platform 17.

[0306] Thus, a support platform 17 is provided on the inner surface of the housing 10, and the body 91 of the elastic pressing member 90 abuts against the support platform 17. This design provides additional support points for the elastic pressing member 90, making the elastic pressing member 90 more securely installed inside the housing 10, and further improving the overall structural stability of the elastic pressing member 90.

[0307] Specifically, the inner surface is the side of the housing 10 facing the internal components of the energy storage power supply 100. The support platform 17 is a protruding structure on the inner surface of the housing 10, used to support the body 91 of the elastic pressure member 90. The support platform 17 can be integrally formed with the inner surface of the housing 10, or it can be mechanically fixed to the inner surface of the housing 10, such as by bonding, bolting, or snap-fitting. There can be one or more support platforms 17, such as two, three, four, or even more. The support platform 17 can have different shapes and sizes, including regular shapes such as circles, squares, and rectangles, as well as irregular shapes.

[0308] Please refer to Figure 35 In some embodiments, the elastic pressing member 90 includes two protrusions 93 disposed on the body 91, the two protrusions 93 being spaced apart, and the support platform 17 being sandwiched between the two protrusions 93.

[0309] Thus, the spacing between the two protrusions 93 allows the support platform 17 to be precisely clamped in the middle. This structure ensures accurate positioning of the elastic pressing member 90 during installation, reducing installation errors and improving assembly efficiency. Furthermore, the elastic pressing member 90 includes two spaced-apart protrusions 93, with the support platform 17 clamped between these two protrusions 93. This design provides more stable support for the elastic pressing member 90, ensuring that it will not shift or wobble within the housing 10, thereby further enhancing the overall structural stability.

[0310] The protrusion 93 is a protruding part on the body 91 of the elastic pressing member 90, used to cooperate with the support platform 17 to provide stable support and positioning. The protrusion 93 can have different shapes and sizes, such as round, square, or rectangular. The protrusion 93 can be integrally formed with the body 91 of the elastic pressing member 90, or it can be a separate component, fixed to the body 91 by welding, bonding, or other methods.

[0311] The support platform 17 can be clamped in different ways, such as direct clamping or clamping through an intermediate component. The clamping force can be controlled by adjusting the shape and size of the protrusion 93.

[0312] 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.

[0313] Thus, during the production process, the elastic pressing member 90 can be fixed to the housing 10 through the engagement of the mounting post 18 and the through hole 911, forming a pre-assembled component. This pre-assembled component can then be directly used when assembling with other parts, greatly improving the efficiency and convenience of assembly.

[0314] Specifically, the through hole 911 is a through hole on the body 91 of the elastic pressing member 90, used to insert the mounting post 18. The shape and size of the through hole 911 can be designed according to the shape and size of the mounting post 18, such as circular, square, elliptical, etc. The number of through holes 911 can be set according to requirements. In order to stably fix the mounting post 18, the number of through holes 911 can be multiple, such as two, three, four or even more.

[0315] Mounting post 18 is a protruding structure on housing 10, used to insert into through hole 911 to fix elastic pressing member 90. Mounting post 18 can have different shapes and sizes, such as round, square, and rectangular. The number of mounting posts 18 can be adapted to the number of through holes 911. Mounting post 18 can be integrally formed with housing 10, or it can be a separate component, fixed to housing 10 by welding, bonding, or other methods.

[0316] Please refer to Figure 35 , Figure 36 and Figure 37 In some embodiments, the elastic pressing member 90 includes a pressing block 94 disposed on the side of the body 91 opposite to the sliding button 80. The elastic pressing member 90 is sandwiched between the housing 10 and the circuit board module 20, and the pressing block 94 abuts against the circuit board module 20.

[0317] Thus, by pressing against the circuit board module 20 with the pressure block 94, the elastic pressing member 90 is stably clamped between the housing 10 and the circuit board module 20. This design ensures that the elastic pressing member 90 will not shift or wobble within the housing 10, thereby guaranteeing its stable pressing effect on the sliding button 80. Furthermore, this design allows the circuit board module 20 to press the elastic pressing member 90 firmly without the need for other additional components, which not only improves the space utilization within the housing 10 but also reduces manufacturing costs.

[0318] Specifically, the pressure block 94 is a protruding part on the body 91 of the elastic pressing member 90, used to contact the circuit board module 20 and provide force. The pressure block 94 can have different shapes and sizes, such as round, square, rectangular, etc.

[0319] Clamping refers to the elastic pressure member 90 being clamped between the housing 10 and the circuit board module 20, and being fixed by the pressure between the two.

[0320] Please refer to Figure 37 In some embodiments, both the sliding button 80 and the circuit board module 20 are disposed on the first housing 11.

[0321] Thus, by placing both the sliding button 80 and the circuit board module 20 on the first housing 11, the assembly process becomes simpler. 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.

[0322] Specifically, the sliding button 80 and the circuit board module 20 can be mounted on the first housing 11 by means of bolt connection, snap-fit ​​connection or adhesive bonding.

[0323] Please refer to Figure 35 In some embodiments, the body 91 is fixed to the housing 10 by fasteners.

[0324] Thus, by fixing the body 91 of the elastic pressing member 90 to the housing 10 with fasteners, the stability of the elastic pressing member 90 installed within the housing 10 can be ensured. The use of fasteners can prevent the elastic pressing member 90 from shifting or loosening during use, thereby ensuring its stable pressing effect on the sliding button 80.

[0325] Specifically, fasteners may include bolts, screws, nuts, or rivets. The housing 10 may have corresponding threaded holes or riveting holes. The number of fasteners may be one or more, such as two, three, four, or even more.

[0326] Please refer to Figure 5 , Figure 6 and Figure 7 The energy storage power supply 100 of this utility model embodiment includes a first shell assembly 103 and a second shell assembly 104. The first shell assembly 103 includes a first outer shell 11 and a circuit board module 20 fixed on the first outer shell 11; the second shell assembly 104 includes a second outer shell 12 and a battery module 30 fixedly mounted on the second outer shell 12, wherein the first outer shell 11 and the second outer shell 12 are detachably connected and form a receiving chamber 13, and the circuit board module 20 and the battery module 30 are both located in the receiving chamber 13.

[0327] Thus, 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 before the whole assembly is installed, which simplifies the overall assembly process and improves assembly efficiency.

[0328] During assembly, the first housing 11 and the circuit board module 20 are assembled into the first housing assembly 103, and the second housing 12 and the battery module 30 are assembled into the second housing assembly 104. Then, the first housing assembly 103 and the second housing assembly 104 are assembled together through the first housing 11 and the second housing 12.

[0329] In summary, the energy storage power supply 100 of this utility model embodiment includes a housing 10, a battery module 30, and a support mesh 50. A ventilation section 110a is provided on the housing 10, and the ventilation section 110a forms a ventilation opening 110; the battery module 30 is disposed inside the housing 10; the support mesh 50 is disposed on the inner side of the housing 10 and is attached to the ventilation section 110a to support the ventilation section 110a.

[0330] In the energy storage power supply 100 of this embodiment, by providing a support mesh 50 on the inner side of the housing 10 and attaching it to the ventilation section 110a to support the ventilation section 110a, the structural strength of the ventilation section 110a can be significantly enhanced. The support mesh 50 not only prevents foreign objects from entering the housing 10 through the ventilation opening 110, but also reduces the risk of breakage of the ventilation section 110a during drops or vibrations, thereby improving the safety of the ventilation section 110a. In addition, the design of the support mesh 50 does not affect the heat dissipation function of the ventilation opening 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.

[0331] Please refer to Figure 38 , Figure 39 , Figure 40 and Figure 41 The energy storage power supply 100 of this utility model embodiment includes: a housing 10, a bracket 31, and battery cells 32. Each battery cell 32 includes a first end 320 and a second end 321 disposed opposite to each other. 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 multiple mounting grooves 121. The assembly method of the energy storage power supply 100 of this utility model embodiment includes:

[0332] S10, the first ends 320 of multiple battery cells 32 are pre-fixed to the fixing groove 310 of the bracket 31. Multiple electrical connectors 33 are provided on the bracket 31. The electrical connectors 33 connect the first electrode 3200 of the battery cell 32 and the second electrode of the adjacent battery cell 32 to form a battery module 30.

[0333] S20, the second end 321 of the battery cell 32 is embedded in the mounting groove 121 and the bracket 31 is fixed to the housing 10 to fix the battery module 30 to the housing 10.

[0334] In the assembly method of the energy storage power supply 100 according to this utility model embodiment, 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 to the bracket 31 through the electrical connector 33 to form a battery module 30. Then, the battery module 30 is fixed to the housing 10 as a whole. This method avoids direct welding operations on the housing 10, reduces the risk of damage to the housing 10 caused by welding, and improves assembly efficiency. At the same time, the fixing groove 310 and the electrical connector 33 on the bracket 31 can reasonably arrange the positions of the battery cell 32 and the electrical connector 33, making the battery module 30 more compact, thereby helping to reduce the overall volume of the energy storage power supply 100.

[0335] Specifically, during assembly, the first end 320 of the battery cell 32 can be pre-fixed to the fixing groove 310 of the bracket 31 by means of clips, bolts, or adhesive. The electrical connector 33 can connect the first electrode 3200 of the battery cell 32 and the second electrode of the adjacent battery cell 32 one by one by means of welding or wire connection to form a battery module 30. The bracket 31 can be fixed to the housing 10 by means of bolt connection, adhesive connection, or clip connection.

[0336] During pre-fixation, the fixing groove 310 and the battery cell 32 can be fitted with an interference fit. Alternatively, adhesive can be applied inside the fixing groove 310 for fixation. Another option is to use a fixture to pre-fix the battery cell 32 to the bracket 31 via the fixture's connection to the bracket 31, and then remove the fixture after welding.

[0337] Please refer to Figure 41 and Figure 42 In some embodiments, the assembly method includes:

[0338] S30, install the electrical connector 33 onto the bracket 31;

[0339] S40, the electrical connector 33 is welded to the first electrode 3200 of the battery cell 32 and the second electrode of the adjacent battery cell 32.

[0340] It should be noted that there is no temporal relationship between steps S30, S40 and step S10. For example, step S30 can be before or after step S10. Similarly, step S40 can be before or after step S10.

[0341] Thus, by first installing the electrical connector 33 onto the bracket 31, and then welding the first electrode 3200 of the battery cell 32 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 guaranteeing that the battery cell 32 is installed in the correct position. Furthermore, welding ensures a stable electrical connection between the first electrode 3200 and the second electrode.

[0342] Specifically, the electrical connector 33 can be installed on the bracket 31 by means of plugging, snap-fitting, etc. Welding is a process of bonding materials by heating or pressurizing, used to enhance the connection strength and conductivity between the electrical connector 33 and the first electrode 3200 and the second electrode. Welding ensures the long-term stability and reliability of the electrical connection. Welding methods can include resistance welding, laser welding, ultrasonic welding, etc.

[0343] Please refer to Figure 41 In some embodiments, mounting the electrical connector 33 onto the bracket 31 includes:

[0344] The first positioning structure 330 of the electrical connector 33 is engaged with the second positioning structure 312 of the bracket 31 to position the electrical connector 33 onto the bracket 31.

[0345] Thus, 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 accurately positioned quickly, reducing the time spent searching for and adjusting the position during assembly and significantly improving assembly efficiency.

[0346] Specifically, the first positioning structure 330 is a component on the electrical connector 33 that mates 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 similar structure.

[0347] The second positioning structure 312 is a component on the bracket 31 that mates with the first positioning structure 330 of the electrical connector 33, ensuring accurate positioning of the electrical connector 33 during installation. The second positioning structure 312 can be a groove, protrusion, hole, or other structure adapted to the first positioning structure 330.

[0348] 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.

[0349] Please refer to Figure 41In some embodiments, the first positioning structure 330 is a protrusion, and the second positioning structure 312 is a positioning hole. Connecting the first positioning structure 330 of the electrical connector 33 with the second positioning structure 312 of the bracket 31 includes:

[0350] Insert the protrusion into the positioning hole.

[0351] Thus, the connection process between the electrical connector 33 and the bracket 31 is simplified by the cooperation of the protrusion and the positioning hole, thereby reducing assembly complexity. Furthermore, since no additional connecting elements (such as screws, bolts, etc.) are required, this method can reduce manufacturing costs.

[0352] Please refer to Figure 43 In some embodiments, the assembly method further includes, before mounting the battery module 30 onto the housing 10:

[0353] The acquisition component 105 is installed on the bracket 31 and connected to the electrical connector 33.

[0354] In this way, the acquisition component 105 is pre-installed on the bracket 31 and connected to the electrical connector 33, which reduces the steps of complex wiring and installation on the housing 10 and significantly improves assembly efficiency.

[0355] Specifically, the data 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 data acquisition component 105 may include a voltage acquisition module, a temperature sensor, or a current sensor. The data acquisition component 105 can be installed on the bracket 31 using methods such as snap-fit, bolt fixing, or adhesive fixing.

[0356] 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, and the housing 10 includes a separate first outer shell 11 and a second outer shell 12, the second outer shell 12 having a mounting groove 121, and the assembly method includes:

[0357] S101, fix the circuit board module 20 to the first housing 11; fix the bracket 31 to the housing 10 to fix the battery module 30 to the housing 10 (step S20), including:

[0358] S21, fix the bracket 31 to the second housing 12 to fix the battery module 30 to the second housing 12.

[0359] Thus, the first outer shell 11 and the second outer shell 12 can serve as independent units of the circuit board module 20 and the battery module 30, respectively. This modular design allows for the separate assembly of the battery module 30 and the circuit board module 20, simplifying the assembly process and improving assembly efficiency.

[0360] 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:

[0361] 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 receiving cavity 13 formed by the first housing 11 and the second housing 12.

[0362] By arranging the electrical connection steps before assembling the housing 10, complex wiring and connection operations can be avoided within the limited space of the housing 10, simplifying the assembly process and improving assembly efficiency. At the same time, it also facilitates the inspection and adjustment of the quality of the electrical connections.

[0363] 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. 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. The first circuit board 21 and the second circuit board 22 are arranged at a certain angle.

[0364] Fixing the circuit board module 20 to the first housing 11 (step S101) includes:

[0365] S1010, the first circuit board 21 is fixed to the first substrate 111;

[0366] S1011, fix the second circuit board 22 to the panel 112.

[0367] Thus, 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 substrate 111 and the panel 112, making the installation and disassembly process more convenient. When maintaining or replacing the circuit board module 20, the corresponding circuit board can be operated individually, reducing maintenance difficulty and cost, and improving repair efficiency.

[0368] 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:

[0369] S50, insert the plug protrusion 220 into the plug hole 210;

[0370] S60, soldering is used to define the insertion protrusion 220 within the insertion hole 210.

[0371] Thus, through the cooperation of the insertion protrusion 220 and the insertion hole 210, the mechanical connection between the first circuit board 21 and the second circuit board 22 is first realized. This initial fixation makes the positional relationship between the two circuit boards more stable, and it is not easy for them to shift during the subsequent soldering process, thereby improving the assembly accuracy and stability.

[0372] After the protrusion 220 is inserted into the socket 210, it is then fixed with solder. This dual connection method not only enhances the mechanical connection strength but also ensures the reliability of the electrical connection. Soldering provides good conductivity, reduces contact resistance, and ensures stable electrical performance between circuit boards.
