[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the energy storage power supply 100 of the embodiment of the present invention includes a housing 10, a circuit board module 20, and a battery module 30. The housing 10 includes a first 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 enclose an accommodation chamber 13; the circuit board module 20 includes an inverter circuit 2141 (such as Figure 10a ), the circuit board module 20 is fixedly installed on the first outer shell 11 and is located inside the accommodation chamber 13; the battery module 30 is fixedly installed on the second outer shell 12 and is located inside the accommodation chamber 13, and the battery module 30 is electrically connected to the circuit board module 20.

[0034] In the energy storage power supply 100 of the embodiment of the present invention, by designing the housing 10 as a detachable first outer shell 11 and second outer shell 12, and respectively fixedly installing the circuit board module 20 and the battery module 30 on the corresponding outer shells, a modular design of the energy storage power supply 100 is achieved. This design allows, during the assembly process, to first independently complete the pre-assembly of the circuit board module 20 and the first outer shell 11, and the battery module 30 and the second outer shell 12, and then combine the whole of the circuit board module 20 and the first outer shell 11 and the whole of the battery module 30 and the second outer shell 12, thereby simplifying the overall assembly process, greatly reducing the assembly complexity, and significantly improving the assembly efficiency.

[0035] Specifically, the housing 10 is an external protection structure of the energy storage power supply 100, used to accommodate and protect internal components. The battery module 30 and the circuit board module 20 are accommodated in the housing 10. The housing 10 can be made of metal, plastic, or other composite materials.

[0036] The detachable connection between the first outer shell 11 and the second outer shell 12 can be a bolt connection, a snap connection, or a plug-in connection, etc. The accommodation chamber 13 is an internal space enclosed by the first outer shell 11 and the second outer shell 12. The accommodation space is used to accommodate the circuit board module 20 and the battery module 30, providing a protected internal environment.

[0037] The circuit board module 20 is the control and management core of the energy storage power supply 100, including various electronic components and control circuits. The circuit board module 20 can be used for the conversion, control, and management of electrical energy to ensure 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 connection, or plug-in connection, etc.

[0038] The inverter circuit 2141 is a circuit that converts direct current into alternating current. The inverter circuit 2141 can achieve the conversion between alternating current and direct current, enabling the energy storage power supply 100 to adapt to different power consumption requirements. It can either convert the direct current of the battery module 30 into alternating current for external output or convert the externally input alternating current into direct current to supply power to the battery module 30.

[0039] The battery module 30 is the energy storage unit of the energy storage power supply 100 and can include multiple battery cells 32. The battery module 30 is used to store electrical energy and provide energy support for the output of the energy storage power supply 100. The battery module 30 can adopt lithium-ion batteries, lead-acid batteries, or other types of batteries, and the specific selection depends on the energy storage requirements and application scenarios. The battery module 30 can be fixedly installed on the second housing 12 by means of bolt connection, snap connection, or plug-in connection, etc.

[0040] Electrical connection means establishing an electrical path between the circuit board module 20 and the battery module 30 through electrical components such as wires and connectors, enabling electrical energy and signals to be transmitted between the circuit board module 20 and the battery module 30. Through electrical connection, the circuit board module 20 can control and manage the battery module 30 to ensure the stable transmission of electrical energy. The electrical connection between the circuit board module 20 and the battery module 30 can be achieved by means of welding, bolt connection, terminal connection, or using wires to connect, etc.

[0041] Please refer to Figure 5 、 Figure 6 and Figure 7 During the assembly process, first, the circuit board module 20 can be fixedly installed on the first housing 11, and the battery module 30 can be fixedly installed on the second housing 12. Then, the first housing 11 and the second housing 12 can be assembled into a complete housing 10 through a detachable connection to form an accommodation chamber 13. Finally, the circuit board module 20 and the battery module 30 can be connected through electrical connection to complete the assembly of the energy storage power supply 100.

[0042] During use, the battery module 30 stores electrical energy and transmits the electrical energy to the circuit board module 20 through electrical connection. The circuit board module 20 converts, controls, and manages the electrical energy to ensure the stable output of the electrical energy.

[0043] Please refer to Figure 1 and Figure 4, in some embodiments, the first housing 11 is formed with a vent 110 communicating with the accommodation chamber 13.

[0044] Thus, by providing the vent 110 on the first housing 11, air circulation can be promoted, the temperature inside the accommodation chamber 13 can be effectively reduced, thereby improving the heat dissipation performance of the energy storage power supply 100, enhancing the operating stability of the energy storage power supply 100, and prolonging the service life of the internal components of the energy storage power supply 100.

[0045] Specifically, the vent 110 is an opening provided on the first housing 11 for promoting air circulation. The vent 110 can be designed as a louver type, a grid type or other forms to prevent foreign objects from entering the interior of the device. The number of vents 110 can be one or more. For example, the number of vents 110 is two, and the two vents 110 are spaced apart on the first housing 11. The shape of the vent 110 can be a regular shape, such as a circle, a square, etc., or an irregular shape.

[0046] Please refer to Figure 4 , in some embodiments, the vent 110 includes an air inlet 1100 and an air outlet 1101, and the air inlet 1100 and the air outlet 1101 are respectively located on opposite sides of the first housing 11.

[0047] Thus, the air inlet 1100 and the air outlet 1101 are respectively located on opposite sides of the first housing 11. This design forms a relatively long air flow path, enabling air to flow through most areas inside the energy storage power supply 100, thereby significantly improving the heat dissipation efficiency.

[0048] Specifically, the opposite sides can be the front and back sides, the left and right sides, or the top and bottom sides of the energy storage power supply 100. For example, for a cuboid-shaped energy storage power supply 100, the air inlet 1100 and the air outlet 1101 can be provided on the left and right sides of the energy storage power supply 100, or in other words, the air inlet 1100 and the air outlet 1101 can be spaced apart along the length direction of the energy storage power supply 100.

[0049] 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 installed on the first substrate 111.

[0050] In this way, by designing the first housing 11 as a combined structure of the first substrate 111 and the panel 112, the circuit board module 20 can be pre-mounted on the first substrate 111, and then the panel 112 and the second housing 12 can be assembled into a complete housing. This step-by-step assembly method simplifies the assembly process, reduces the assembly complexity, and improves the assembly efficiency.

[0051] Specifically, the first substrate 111 is a part of the first housing 11 and can be a flat plate-like structure. The shape of the first substrate 111 can be a regular shape such as a rectangle or a circle, or an irregular shape. For example, the shape of the first substrate 111 is a rectangle. The first substrate 111 can be directly connected to the panel 112, or can be spaced from the panel 112 and indirectly connected through other structures. Structures such as mounting holes and slots for fixedly mounting the circuit board module 20 can be provided on the first substrate 111. 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.

[0052] The panel 112 is another part of the first housing 11 and can be a flat plate-like structure. The shape of the panel 112 can be a regular shape such as a rectangle or a circle, or an irregular shape. For example, the shape of the panel 112 is a rectangle. The panel 112 can be connected to the second housing 12 by means of bolt connection, snap connection, or plug-in connection.

[0053] 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.

[0054] In this way, by dividing the circuit board module 20 into the first circuit board 21 and the second circuit board 22 and fixedly mounting them on the first substrate 111 and the panel 112 respectively, a distributed installation of the circuit board can be achieved. This distributed installation method allows different circuit board parts to be processed separately during the assembly process, thus simplifying the assembly steps and improving the assembly efficiency.

[0055] 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.

[0056] The first circuit board 21 and the second circuit board 22 can be electrically connected by means of welding, bolt connection, terminal connection, or wire connection.

[0057] In some embodiments, the first circuit board 21 is fixed to the first substrate 111 by screws.

[0058] In some embodiments, the second circuit board 22 is fixed to the panel 112 by screws.

[0059] 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.

[0060] In this way, screw fixation provides a firm mechanical connection, ensuring that the circuit board remains stable in complex environments such as vibration and shock, and preventing electrical failures caused by loose connections. Moreover, screw fixation is a common fastening method with easily available tools and simple operations, facilitating installation and maintenance. When the circuit board needs to be replaced or repaired, simply loosening the screws can complete the disassembly, improving the maintenance efficiency.

[0061] 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 enhancing the connection strength. Screw fixation can be combined with accessories such as washers and spring washers to enhance the fixation effect.

[0062] Please refer to Figure 1 and Figure 9 , in some embodiments, an opening 112a is provided on the panel 112. 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 faces the opening 112a.

[0063] In this way, the output port 102a faces the opening 112a on the panel 112, facilitating direct external connection by the user through the opening 112a without the need for additional adapter devices or complex wiring, enhancing the user experience.

[0064] 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.

[0065] The opening 112a can be an opening formed on the panel 112. The number of openings 112a can be one or more. The number of openings 112a can correspond one-to-one with the output ports 102a.

[0066] The output port 102a can be a USB port 101 or a vehicle charging port 102.

[0067] Please refer to Figure 2 and Figure 9, in some embodiments, the first circuit board 21 is arranged horizontally, and the second circuit board 22 is arranged vertically.

[0068] In this way, 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 the circuit boards, and improving the space utilization rate. In addition, the horizontal and vertical layouts make 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 the maintenance efficiency.

[0069] Specifically, arranging horizontally means that the first circuit board 21 is installed along the horizontal direction. By arranging horizontally, the first circuit board 21 can more effectively utilize the space in the horizontal direction and avoid interference with other components.

[0070] Arranging vertically means that the second circuit board 22 is installed along the vertical direction. By arranging vertically, the second circuit board 22 can more effectively utilize the space in the vertical direction and optimize the overall layout.

[0071] Please refer to Figure 2 , in some embodiments, both the first circuit board 21 and the second circuit board 22 are fixed on the first housing 11.

[0072] In this way, the first circuit board 21 and the second circuit board 22 are fixed on the first housing 11, and this fixing method helps to maintain a reasonable layout between the circuit boards, avoid overlap and interference between the circuit boards, and further improve the utilization rate of the space inside the energy storage power supply 100.

[0073] If the first housing 11 and the second housing 12 are not detachable, the second housing 12 will interfere with the installation of the first circuit board 21 and the second circuit board 22. Therefore, the detachable connection between the first housing 11 and the second housing 12 enables the first circuit board 21 and the second circuit board 22 to be pre-fixed on the first housing 11, and then the second housing 12 is connected to the first housing 11 to complete the assembly of the entire energy storage power supply 100. This modular design improves the production efficiency and reduces the assembly time.

[0074] Specifically, both the first circuit board 21 and the second circuit board 22 can be fixed on the first housing 11 by means of bolt connection, snap connection or plug connection.

[0075] 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 projection 220, and the plug projection 220 is inserted into the plug hole 210 to fixedly connect the first circuit board 21 and the second circuit board 22.

[0076] Thus, the design of the insertion holes 210 and the insertion protrusions 220 allows for quick connection and disconnection between circuit boards without the use of tools, significantly improving the efficiency of assembly and maintenance.

[0077] Specifically, the insertion hole 210 is an opening or groove provided on the circuit board for accommodating the insertion protrusion 220. The insertion hole 210 can be designed in different shapes (such as circular, square, rectangular, etc.) and sizes to adapt to different insertion protrusions 220. The insertion protrusion 220 is a protruding part provided on the circuit board for inserting into the insertion hole 210. The number of both the insertion hole 210 and the insertion protrusion 220 can be multiple.

[0078] Please refer to Figure 10 , in one example, the first circuit board 21 is provided with insertion holes 210, and the second circuit board 22 is provided with insertion protrusions 220. In another example, the first circuit board 21 is provided with insertion protrusions 220, and the second circuit board 22 is provided with insertion holes 210. The insertion protrusion 220 is fixed in the insertion hole 210 by soldering. The first circuit board 21 is also provided with a female header 21a, and the second circuit board 22 is also provided with a male pin 22a. The electrical connection between the first circuit board 21 and the second circuit board 22 is achieved by inserting the male pin 22a into the female header 21a. During installation, simply insert the male pin 22a into the slot of the female header 21a to complete the connection without the need for additional tools or equipment, which is convenient and fast.

[0079] Please refer to Figure 11 , in some embodiments, the second housing 12 is provided with an insertion slot 120, and the edge of the second circuit board 22 away from the first circuit board 21 is inserted into the insertion slot 120.

[0080] Thus, the insertion method simplifies the installation and disassembly 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 complex connection steps, significantly improving the assembly efficiency.

[0081] Specifically, the insertion slot 120 is a groove provided on the second housing 12 for accommodating the edge of the second circuit board 22. The width of the insertion slot 120 can be slightly larger than the width of the edge of the second circuit board 22 to facilitate 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 space, which can compensate for the processing error of the second circuit board 22.

[0082] The insertion slot 120 can be formed on the inner surface of the second housing 12 or formed by other means. For example, two columns are provided on the inner surface of the second housing 12, and the insertion slots 120 are provided on the two columns and are aligned with each other.

[0083] Please refer to Figure 10a, in some embodiments, the first circuit board 21 includes a functional circuit 214. The functional circuit 214 includes a battery management circuit 2140, an inverter circuit 2141, and a solar charging circuit 2142.

In this way, the battery management circuit 2140, the inverter circuit 2141, and the solar charging circuit 2142 are integrated on the first circuit board 21, realizing a multi-functional integrated design. This integrated design reduces the number of components, simplifies the circuit layout, improves the compactness and reliability of the device, and improves the assembly efficiency.

[0084] 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, to ensure that the battery operates within a safe range. This helps to extend the service life of the battery and improve the reliability and safety of the battery.

The battery management circuit 2140 can monitor the voltage, current, and temperature of the battery module 30, 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 the life of the battery module 30. The battery management circuit 2140 can include functions such as overcharge protection, over-discharge protection, and short-circuit protection.

[0086] The solar charging circuit 2142 is a circuit used to convert the electrical energy generated by the solar panel into electrical energy suitable for storage in the battery module 30. The solar charging circuit 2142 can be connected to the solar panel. The solar panel is used to convert solar energy into electrical energy, and the solar charging board is used to convert the electrical energy of the solar panel into electrical energy that can be stored in the energy storage power supply 100.

[0088] In this way, the output circuit allows the energy storage power supply 100 to be directly connected to an external circuit, and the user can conveniently use the energy storage power supply 100 to power various devices without the need for additional switching equipment or complicated connection steps, thereby improving the convenience of use.

[0089] Specifically, the output circuit refers to a circuit for transmitting electric energy from the energy storage power supply 100 to an external device. The output circuit may include a variety of interfaces, such as a USB interface, a DC output interface, an AC output interface, etc., to meet the needs of different devices.

[0090] External circuit electrical connection refers to the electrical connection between the energy storage power supply 100 and an external device. The external circuit electrical connection can be wired or wireless, and the wired connection includes a USB cable, a power adapter cable, etc.

[0091] 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, etc. It should be noted that the values ​​here are only examples for easy understanding and cannot be used as limitations on the embodiments of the present invention.

[0092] Please refer to Figure 10a In some embodiments, the second circuit board 22 includes a DC conversion circuit 22b, which is electrically connected to the battery module 30 through the battery management circuit 2140, and outputs the electrical energy of the battery module 30 through the output port 102a after DC conversion.

[0093] In this way, the electric energy after DC conversion can be used to power various DC devices, such as mobile devices, lighting equipment, etc., through the output port 102a, thereby enhancing the versatility and practicality of the energy storage power supply 100 and making it suitable for a variety of application scenarios.

[0094] Please refer to Figure 1 In some embodiments, the output circuit includes at least one of a USB port 101 and a vehicle charging port 102. In one embodiment, the USB port 101 is exposed through a panel 112. In one embodiment, the vehicle charging port 102 is exposed through a panel 112. In one embodiment, the USB port 101 and the vehicle charging port 102 are exposed through a panel 112.

[0095] In this way, by integrating the USB port 101 and the vehicle charging port 102 , the dependence on external adapters or converters is reduced, thereby reducing the user's usage cost.

[0096] Specifically, the USB port 101 is a Universal Serial Bus interface for connecting various USB devices. The USB port 101 can provide a standardized interface, facilitating users to connect and charge various USB devices such as mobile phones, tablets, laptops, etc. The USB port 101 can support multiple standards, such as USB-A, USB-C, USB-B, etc., and common output powers include 5V / 2A, 9V / 2A, 12V / 1.5A, etc. The USB port 101 can be designed to support fast charging protocols such as QC3.0, PD, etc.

[0097] The in-vehicle charging port 102 is a charging interface designed specifically for in-vehicle devices and can serve as a charging interface for in-vehicle devices. The in-vehicle charging port 102 can provide a charging interface for in-vehicle devices, facilitating users to charge their devices in the in-vehicle environment. The in-vehicle charging port 102 can support outputs such as 12V, 24V, etc., and can be designed to support multiple in-vehicle devices such as mobile phones, tablets, in-vehicle navigation devices, etc.

[0098] 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 with one end mounted on the bracket 31. The second housing 12 is formed with a plurality of mounting grooves 121, and the other end of the battery cell 32 is embedded in the mounting grooves 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.

[0099] In this way, the design of the bracket 31 allows one end of the plurality of battery cells 32 to be pre-mounted on the bracket 31 during the assembly process, and then the entire battery module 30 is embedded in the mounting grooves 121 to fix the entire battery module 30 to the second housing 12, simplifying the assembly steps and improving the assembly efficiency.

[0100] The mounting grooves 121 simplify the installation process of the battery cells 32. The battery cells 32 can be fixed simply by embedding one end of the battery cells 32 into the mounting grooves 121, without the need for additional fixing tools or complex connection steps, significantly improving the assembly efficiency. Moreover, the design of the mounting grooves 121 enables one end of the battery cells 32 to be firmly embedded in the second housing 12, preventing the battery cells 32 from shifting or loosening under vibration or impact and improving the installation stability of the battery module 30.

[0101] Specifically, the bracket 31 is a structural component for fixing and supporting the battery cells 32. The bracket 31 can provide stable mechanical support to ensure that the battery cells 32 do not shift or loosen during operation; The bracket 31 can be fixedly installed on the second housing 12 by means such as bolt connection, snap connection or plug connection. The bracket 31 and the second housing 12 can also be of an integrally formed structure, which can reduce the connection gaps and weak points when the bracket 31 is connected to the second housing 12, thereby enhancing the overall rigidity of the bracket 31 and the second housing 12.

[0102] A plurality of mounting grooves 121 can correspond to a plurality of battery cells 32 one by one. The mounting grooves 121 can be formed by the inner wall of the second housing 12 and the rib structures provided on the inner wall of the second housing 12. The mounting grooves 121 are used to fix the battery cells 32. The groove walls of the mounting grooves 121 can be larger than the diameter of the battery cells 32. The shape of the inner wall of the mounting grooves 121 can be similar to the shape of the outer surface of the battery cells 32. The number of the mounting grooves 121 can be two, three, four or even more.

[0103] Please refer to Figure 12 , in some embodiments, the second housing 12 includes a second substrate 122 and a second side plate 123 connected to the second substrate 122. The second side plate 123 is formed with mounting grooves 121, and the second side plate 123 is connected to the first housing 11.

[0104] In this way, the mounting grooves 121 on the second side plate 123 can optimize the layout of the battery cells 32, making the connection between the battery cells 32 and the housing more compact, reducing unnecessary space occupation, and improving space utilization.

[0105] In addition, by designing the second housing 12 as a combined structure of the second substrate 122 and the second side plate 123, a step-by-step installation of the battery cells 32 can be achieved. This step-by-step installation method allows different component parts to be processed separately during the assembly process, thereby simplifying the assembly steps and improving the assembly efficiency.

[0106] Specifically, the second substrate 122 is a part of the second housing 12 and is usually 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 an irregular shape. For example, the shape of the second substrate 122 is a rectangle.

[0107] The second side plate 123 is another part of the second housing 12 and can be a plate-like structure perpendicular to the second substrate 122, used to connect to the first housing 11 and form a part of the accommodation chamber 13. The second side plate 123 and the first housing 11 can be connected by means such as bolt connection, snap connection or plug connection.

[0108] Please refer to Figure 12, in some embodiments, the second substrate 122 is provided with support ribs 1221, and the support ribs 1221 are formed with first limiting grooves 1222, and the battery cell 32 abuts against the groove walls of the first limiting grooves 1222.

[0109] In this way, the support ribs 1221 can not only provide a heat dissipation function, but also provide pre-positioning for the battery cell 32, thereby facilitating the installation of the battery cell 32.

[0110] Specifically, the number of the support ribs 1221 can be one or more. For example, the number of the support ribs 1221 can be two, and the two support ribs 1221 are arranged in parallel on the surface of the second substrate 122 facing the battery cell 32, and the two support ribs 1221 are both formed with a plurality of first limiting grooves 1222, and each first limiting groove 1222 is used for limiting 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.

[0111] 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 in a cylindrical shape, and the shape of the first limiting groove 1222 can be an arc shape.

[0112] Please refer to Figure 12 , Figure 12a , Figure 13 and Figure 14 , in some embodiments, the battery cell 32 includes a first end 320 and a second end 321 along its length direction, a pressure relief structure 32a is formed at the second end 321 of the battery cell 32, the second end 321 of the battery cell 32 is embedded in the installation groove 121, and a support structure 121a is arranged in the installation groove 121, and the support structure 121a abuts against the second end 321 of the battery cell 32, so that a certain distance is formed between the second end 321 and the bottom of the installation groove 121 to form a pressure relief groove 121b, and the pressure relief groove 121b communicates with the accommodation chamber 13.

[0113] In this way, when the battery cell 32 undergoes thermal runaway, the generated high-pressure gas can be discharged in time through the pressure relief groove 121b, avoiding the accumulation of gas inside the battery module 30 and causing an explosion, and significantly improving the safety performance of the energy storage power supply 100 in the case of thermal runaway. And, the pressure relief groove 121b can communicate with the pressure relief structures 32a of multiple battery cells 32, so that the pressure relief structure 32a of any battery cell 32 in the battery module 30 can achieve the purpose of runaway pressure relief.

[0114] Specifically, the pressure relief structure 32a can be an explosion-proof valve or a notch provided at the second end 321 of the battery cell 32. For example, the pressure relief structure 32a can be an explosion-proof valve, and a weak position or a weak device is provided inside the explosion-proof valve. When the pressure of the battery cell 32 rises, the weak position will be opened by the pressure, thereby releasing the high-pressure gas of the battery cell 32 to prevent the battery cell 32 from exploding or catching fire due to abnormal conditions such as overcharging, over-discharging, and short-circuiting. For another example, the pressure relief structure 32a can be a notch formed by machining at the second end 321 of the battery cell 32, and the above-mentioned weak position is formed at the notch.

[0115] The support structure 121a can be a protrusion protruding from the inner wall of the accommodation chamber 13. For example, the support structure 121a can be a rib protruding from the inner wall of the accommodation 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 can be spaced from the inner wall of the accommodation chamber 13, so that a pressure relief groove 121b can be formed between the battery cell 32 and the inner wall of the accommodation chamber 13.

[0116] Please refer to Figure 12 , in some embodiments, a notch 121c is provided on the side wall of the installation groove 121, and the pressure relief groove 121b communicates with the accommodation chamber 13 through the notch 121c.

[0117] In this way, the communication between the pressure relief groove 121b and the accommodation chamber 13 is realized by providing the notch 121c on the side wall of the installation groove 121. 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 processing difficulty of the notch 121c is lower, which can reduce the complexity of the manufacturing process, lower the production cost, and improve the production efficiency. Moreover, 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.

[0118] Specifically, the number of the notches 121c can be one or more. For example, the number of the notches 121c can be two, three, four or even more. Multiple notches 121c can be symmetrically provided on the side wall of the installation groove 121, which can improve the pressure relief effect.

[0119] Please refer to Figure 12 , in some embodiments, multiple installation grooves 121 are arranged in parallel, and two adjacent installation grooves 121 are communicated through the notch 121c, and the notch 121c on the side wall of one of the installation grooves 121 communicates with the accommodation chamber 13.

[0120] In this way, by opening a notch 121c on the side wall of the installation groove 121, the pressure relief groove 121b is communicated with the accommodation chamber 13, so that the high-pressure gas ejected by the battery cell 32 can be guided out of the pressure relief groove 121b to achieve the purpose of pressure relief.

[0121] Moreover, by arranging a plurality of installation grooves 121 in parallel, and communicating two adjacent installation grooves 121 through the notch 121c, and the notch 121c on the side wall of one of the installation grooves 121 is communicated with the accommodation chamber 13. This design forms a continuous pressure relief channel. When any battery cell 32 undergoes thermal runaway, the generated high-pressure gas can not only be discharged into the accommodation chamber 13 through the notch 121c of its own pressure relief groove 121b, but also diffuse and be discharged into the entire pressure relief channel through the notch 121c of the adjacent installation groove 121 in sequence.

[0122] Specifically, the sizes of the notch 121c communicating two adjacent installation grooves 121 and the notch 121c communicating with the accommodation chamber 13 can be the same or different. The notch 121c can be formed by mechanical processing or by injection molding. The shape of the notch 121c can be set arbitrarily according to requirements, and the embodiments of the present invention do not limit this.

[0123] Please refer to Figure 12 and Figure 14 , in some embodiments, a gap is formed between the side wall of the installation groove 121 and the side wall of the battery cell 32, and the pressure relief groove 121b is communicated with the accommodation chamber 13 through the gap.

[0124] In this way, by forming a gap between the side wall of the installation groove 121 and the side wall of the battery cell 32, the high-pressure gas ejected by the battery cell 32 can flow from the gap into the accommodation chamber 13 to achieve the purpose of pressure relief.

[0125] Moreover, by using the gap between the side wall of the installation groove 121 and the side wall of the battery cell 32 to realize the communication between the pressure relief groove 121b and the accommodation chamber 13, this design does not require additional processing of complex pressure relief channels or communication structures, reduces the complexity of the manufacturing process, reduces the production cost, and improves the production efficiency.

[0126] Specifically, the diameter of the battery cell 32 can be adapted to the diameter of the installation groove 121, so that a gap is formed between the side wall of the installation groove 121 and the side wall of the battery cell 32, and the pressure relief groove 121b is communicated with the accommodation chamber 13 through the gap, so that the high-pressure gas released by the battery cell 32 into the pressure relief groove 121b can flow into the accommodation chamber 13 from the gap.

[0127] Please refer to Figure 12, in 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.

[0128] In this way, 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.

[0129] 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.

[0130] In this way, the provision of the rib forms a certain distance between the second end 321 of the battery cell 32 and the bottom of the mounting groove 121, thus ensuring the formation of the pressure relief groove 121b and its communication with the accommodation chamber 13. Moreover, the rib can effectively disperse the pressure received by the second end 321 of the battery cell 32, prevent the battery cell 32 from shaking or displacing in the mounting groove 121, and improve the overall structural stability of the battery module 30.

[0131] Specifically, the rib can have various forms, such as: linear rib, arc-shaped rib, etc. For example, the rib can be arc-shaped, and the arc-shaped rib can be attached to the side wall of the battery cell 32 and be adjacent to the mounting groove 121. Since the rib directly abuts against the second end 321 of the battery cell 32, if the second end 321 is subjected to a large pressure and collapses, it may cause a short circuit of the battery cell 32. However, the arc-shaped rib is arranged adjacent to the mounting groove 121, and it abuts against the edge position of the second end 321 of the battery cell 32, and the pressure is more transmitted to the side wall of the battery cell 32 rather than the end, which can greatly reduce the risk of short circuit of the battery cell 32.

[0132] The rib and the side wall of the mounting groove 121 can be an integrally formed structure, which can reduce connection gaps and weak points, thereby improving the structural rigidity of the rib and thus enhancing the support performance of the rib. The rib can be a continuous structure, which is easy to manufacture and reduces the manufacturing cost.

[0133] Please refer to Figure 12 and Figure 14 , in some embodiments, the number of ribs is two, the two ribs are arranged oppositely, and the two ribs form the pressure relief groove 121b.

[0134] In this way, two convex ribs are arranged oppositely to form a pressure relief groove 121b. This design realizes the effective support and pressure relief functions for the battery cell 32 without increasing the additional space occupation. The two convex ribs can evenly disperse the pressure received by the second end 321 of the battery cell 32, prevent the battery cell 32 from tilting or shaking in the installation groove 121, and further improve the overall structural stability of the battery module 30. Especially when the energy storage power supply 100 is subjected to vibration or drop, it can better protect the battery cell 32 and reduce the risk of damage to the battery cell 32.

[0135] Specifically, the two convex ribs can be of a symmetrical structure, which can provide more uniform support for the battery cell 32.

[0136] Please refer to Figure 12 and Figure 14 , in some embodiments, the battery cell 32 is a cylindrical battery, and the convex rib includes a support portion 121e and a connecting portion 121f. The support portion 121e is arranged in an arc shape in the installation groove 121. The connecting portion 121f penetrates through two installation grooves 121 and is respectively connected to the two support portions 121e at both ends. The two convex ribs penetrate through multiple installation grooves 121 and form a guiding channel 121d. The guiding channel 121d communicates with the accommodating chamber 13, and the pressure relief structure 32a faces the guiding channel 121d.

[0137] In this way, when any one of the battery cells 32 has a thermal runaway, the guiding channel 121d can guide the high-pressure gas and quickly discharge the high-pressure gas, reducing the accumulation and spread of the high-pressure gas in the battery module 30. This design helps to inhibit the spread of thermal runaway among multiple battery cells 32, protects other battery cells 32 from being affected by thermal runaway, and further improves the safety of the energy storage power supply 100. The arc-shaped support portion 121e can stably support the cylindrical battery and prevent the cylindrical battery from shaking. The connecting portion 121f penetrates through two installation grooves 121 and is respectively connected to the two support portions 121e at both ends. This design not only enhances the stability of the battery cell 32 in a single installation groove 121, but also connects the adjacent support portions 121e through the connecting portion 121f, improving the structural stability of the entire battery module 30.

[0138] Specifically, the inner wall surfaces of the two convex ribs can form the guiding channel 121d. The guiding channel 121d can be formed with an open mouth. The open mouth can communicate with the accommodating chamber 13. The bottom wall of the second end 321 of the battery cell 32 can be located in the guiding channel 121d. The pressure relief structure 32a can be arranged on the bottom wall of the second end 321 of the battery cell 32. When the battery cell 32 has a thermal runaway, the high-pressure gas released by the pressure relief structure 32a can enter the guiding channel 121d and be discharged to the accommodating chamber 13 under the guidance of the guiding channel 121d.

[0139] The connecting part 121f and the supporting part 121e can be integrally formed structures, which can reduce connection gaps and weak points, thereby enhancing the overall structural rigidity of the connecting part 121f and the supporting part 121e.

[0140] 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 plate 123 are disposed opposite to each other.

[0141] In this way, the layout of the first substrate 111, the second substrate 122, the panel 112 and the second side plate 123 makes it easy to install the first housing 11 and the second housing 12, thereby improving the assembly efficiency.

[0142] 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, and the second end 321 is embedded in the mounting groove 121.

[0143] In this way, through the cooperation of the first electrode 3200, the second electrode 3201 and the electrical connector 33, the electrical connection between multiple battery cells 32 can be quickly realized, and multiple battery cells 32 can be assembled as a whole, simplifying the assembly process and improving the assembly efficiency. The second end 321 of the battery cell 32 is embedded in the mounting groove 121. Combined with the fixation of the first electrode 3200, the second electrode 3201 and the electrical connector 33, the stability of the battery cell 32 in a vibration or impact environment is ensured, and the risk of displacement or loosening is reduced.

[0144] 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 a battery module 30 to provide 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, etc. The battery cell 32 can be designed in different shapes and sizes, such as cylindrical, square or soft-pack, etc.

[0145] The first electrode 3200 can be the positive electrode. The second electrode 3201 can be the negative electrode. Taking a lithium-ion battery as an example, the positive electrode can include a positive electrode current collector and a positive electrode active material layer. The material of the positive electrode current collector can be aluminum, and the positive electrode active material layer can include positive electrode active materials such as lithium cobaltate, lithium iron phosphate, ternary lithium, or lithium manganate, etc.; the negative electrode plate can include a negative electrode current collector and a negative electrode active material layer. The material of the negative electrode current collector can be copper, and the negative electrode active material layer can include negative electrode active materials such as carbon or silicon, etc.

[0146] The electrical connector 33 is an electrical connection component used to connect adjacent battery cells 32. The electrical connector 33 realizes the electrical connection between adjacent battery cells 32 by cooperating with the electrodes of different battery cells 32 to ensure the stable transmission of current. The electrical connector 33 can adopt various forms such as connecting pieces, connecting wires, welding points, etc. The material of the electrical connector 33 can be a metal with good electrical conductivity such as copper, aluminum, etc. The electrical connector 33 can be designed to have protection functions such as an insulating layer, an anti-loosening structure, etc.

[0147] Please refer to Figure 17 、 Figure 18 、 Figure 19 and Figure 19a , in some embodiments, the battery module 30 and the circuit board module 20 are spaced apart along the first direction v of the accommodation 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, and 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, the first low region 35 and the second high region 23 partially overlap in the first direction v, and 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.

[0148] In this way, the first low region 35 of the battery module 30 can provide a clearance space for the second high region 23 of the circuit board module 20, and the second low region 24 of the circuit board module 20 can provide a clearance space for the first high region 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 structurally compact, significantly improves the space utilization rate of the accommodation chamber 13, reduces the overall volume, and enhances the portability of the energy storage power supply 100.

[0149] Specifically, for the cuboid-shaped 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.

[0150] The height difference refers to different height regions of the battery module 30 or the circuit board module 20 in the first direction v. Overlap means that the projection regions of the battery module 30 and the circuit board module 20 in the first direction v or the second direction h cover each other.

[0151] 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.

[0152] Thus, by dividing the circuit board module 20 into the first circuit board 21 and the second circuit board 22 and forming the second high region 23 and the second low region 24 on the first circuit board 21, the space of the accommodation chamber 13 can be utilized more flexibly. The height difference 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 the space utilization rate.

[0153] 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 arranged on the top of the second housing 12, the circuit board module 20 includes a board body 211 and functional elements 20b arranged on the board body 211, the board body 211 is arranged on the top of the first housing 11, and the functional elements 20b are arranged from the board body 211 towards the battery module 30.

[0154] Thus, this layout can shorten the electrical connection distance between the functional elements 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.

[0155] Specifically, the functional elements 20b may include sensors, controllers, communication modules, etc. The functional elements 20b can implement various functions of the circuit board module 20, such as monitoring the battery state, controlling the charging and discharging process, etc. The functional elements 20b may include a variety of electrical components with different heights and functions. For example, the functional elements 20b may include a first heating element 230 and a second heating element 240.

[0156] Please refer to Figure 16 and Figure 18 , in some embodiments, the board body 211 is fixed to the housing 10, and the functional elements 20b are arranged along the first direction v and towards the battery module 30, so that the circuit board module 20 forms a second high region 23 and a second low region 24. Thus, by optimizing the layout of the functional elements 20b, the circuit board module 20 can form a second high region 23 and a second low region 24, so as to be able to form an interleaved arrangement with the first high region 34 and the first low region 35 of the battery module 30 to improve the space utilization rate of the accommodation chamber 13.

[0157] Please refer to Figure 18 , in some embodiments, the second high region 23 has a first heating element 230, the second low region 24 has a second heating element 240, and the heat generation amount of the first heating element 230 is greater than that of the second heating element 240.

[0158] In this way, by arranging the first heating element 230 with a large heat generation amount in the second high region 23, the relatively open space of the second high region 23 or an additional heat dissipation structure can be utilized to improve the heat dissipation efficiency. And the second heating element 240 with a small heat generation amount is arranged in the second low region 24. Even if the space in the second low region 24 is relatively compact, the performance will not be affected due to poor heat dissipation.

[0159] Specifically, the first heating element 230 can be an element with a large heat generation amount on the circuit board, such as a MOS transistor, an inductor, a transformer, and heat dissipation fins, etc. The second heating element 240 can be an element with a small heat generation amount on the circuit board, such as a connector, a capacitor, etc.

[0160] In other embodiments, components with a higher height are placed in the second high region 23, and components with a lower height are placed in the second low region 24.

[0161] 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 arranged 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 air flow for cooling the second low region 24.

[0162] In this way, the position of the cooling fan 212 enables the cooling fan 212 to cool the second high region 23 and the second low region 24 simultaneously, and the cooling effect on the second high region 23 is better, which can effectively reduce the temperature of the first heating element 230 with a large heat generation amount. This active heat dissipation design can significantly improve the heat dissipation efficiency of the energy storage power supply 100, especially under high-load working conditions, ensuring that the first heating element 230 operates within a safe temperature range.

[0163] In addition, the cooling fan 212 forms at least part of the second high region 23, which enables the cooling fan 212 to select a fan with a larger wind force, thereby being able to provide a better cooling effect.

[0164] Specifically, the cooling fan 212 is an active cooling device that generates an air flow by rotation to remove heat. The cooling fan 212 can be arranged on the board body 211 by means of bolt connection or other mechanical connection methods. The cooling fan 212 can suck air or exhaust air. When the cooling fan 212 is configured to blow air, the cooling fan 212 can form a cooling air flow towards the second low region 24; when the cooling fan 212 is configured to exhaust air, the cooling fan 212 can form a cooling air flow towards the second high region 23.

[0165] Please refer to Figure 16 、 Figure 17 and 18 , in some embodiments, the first circuit board 21 further includes an air duct element 213 arranged on the board body 211. The air duct element 213 forms an air flow channel leading from the cooling fan 212 to the second high region 23, and the air duct element 213 forms part of the second low region 24.

[0166] In this way, the air flow channel formed by the air duct element 213 can guide the air flow generated by the cooling fan 212 to flow more directly to the heating elements in the second high region 23, thereby improving the heat dissipation efficiency. This directional heat dissipation design can ensure that the first heating element 230 arranged in the second high region 23 is cooled more effectively, especially under high-load working conditions.

[0167] Specifically, the air duct element 213 is a structural component for guiding air flow. The inlet of the air duct element 213 is close to the second high region 23, and the outlet of the air duct element 213 is close to the air inlet 1100 of the cooling fan 212, so that under the air exhaust action of the cooling fan 212, the air flow enters the interior of the air duct element 213 through the second low region 24, flows through the second high region 23, and is discharged through the cooling fan 212. The heat generation amount in the second low region 24 is relatively low, and the temperature of the air flow will not be overheated after flowing through the second low region 24. When flowing to the second high region 23, the temperature of the air flow is relatively low, which is more conducive to taking away the heat in the second high region 23. The air duct element 213 can be made of plastic or metal materials. The air duct element 213 can be an air guide cover, an air guide pipe or other similar structures. For example, the air duct element 213 can be an air guide pipe made of plastic material. The inlet of the air guide pipe is close to the air outlet 1101 of the cooling fan 212, and the outlet of the air guide pipe is arranged close to the second high region 23.

[0168] Please refer to Figure 17 and Figure 19 , in some embodiments, the bracket 31 is fixedly installed on the housing 10, and part of the 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.

[0169] In this way, 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 an avoidance space for the circuit board module 20 or other components. This design significantly improves the space utilization rate of the accommodation chamber 13, making the overall structure of the energy storage power supply 100 more compact.

[0170] Specifically, the bracket 31 can be fixedly installed on the housing 10 by means such as bolt connection, snap connection, or plug connection. Two layers of battery cells 32 can be stacked in the first high region 34, and one layer of battery cells 32 can be stacked in the first low region 35, so that the battery cells 32 in different regions of the battery module 30 have a height difference to form the first high region 34 and the first low region 35.

[0171] Please refer to Figure 17 、 Figure 19 and Figure 20 , in some embodiments, the energy storage power supply 100 includes a heat insulation member 40 disposed between the battery module 30 and the circuit board module 20, and the heat insulation member 40 covers the battery module 30.

[0172] In this way, the heat insulation member 40 effectively isolates the heat transfer between the battery module 30 and the circuit board module 20, prevents the heat generated by the battery module 30 from affecting the normal operation of the circuit board module 20, improves the thermal stability of the circuit board module 20, and avoids the performance degradation or shortened lifespan of the circuit board module 20 caused by overheating.

[0173] Specifically, the heat insulation member 40 is a component for reducing heat transfer and can be made of a low thermal conductivity material such as ceramic fiber, asbestos, or aerogel. The heat insulation member 40 can be designed in a plate shape, sheet shape, or other suitable shapes.

[0174] Covering the battery module 30 means that the heat insulation member 40 completely covers the battery module 30, or in other words, the orthographic projection of the battery module 30 on the heat insulation member 40 is located within the heat insulation member 40.

[0175] 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.

[0176] Thus, the shielding member 25 is disposed on the side of the circuit board module 20 facing away from the battery module 30, which can effectively guide and dissipate the heat generated by the circuit board module 20, avoid heat accumulation, and improve the heat dissipation efficiency. By dissipating heat in a timely manner, the risk of failure of the circuit board module 20 caused by overheating is reduced, and the reliability of the circuit board module 20 under long-term operation or high-load conditions is improved. Moreover, by reducing electromagnetic interference, the shielding member 25 helps to improve the signal integrity and reliability of the circuit board module 20, ensuring the accuracy and stability of data transmission.

[0177] Specifically, the shielding member 25 is a component for dissipating heat and can be made of high thermal conductivity materials such as aluminum, copper, or graphite. The shielding member 25 can be in various forms, such as heat sinks, heat pipes, fans, thermal paste, etc. The heat dissipation method of the shielding member 25 can be passive heat dissipation or active heat dissipation. The shielding member 25 can achieve the heat dissipation function in various ways, such as increasing the surface area, using thermal conductive materials, designing air flow channels, etc.

[0178] The shielding member 25 can be made of electromagnetic shielding materials (such as metal plates or conductive coatings), which can effectively shield the electromagnetic interference generated by the circuit board module 20, prevent its influence on other surrounding electronic devices, and at the same time prevent external electromagnetic interference from entering the circuit board module 20, ensuring its normal operation. In the case where both heat dissipation and electromagnetic interference shielding functions are required, the shielding member 25 can be selected as an aluminum plate, a copper plate, etc.

[0179] In some embodiments, the shielding member 25 abuts against the housing 10.

[0180] Thus, when the shielding member 25 abuts against the housing 10, the heat generated by the circuit board module 20 can be directly conducted to the housing 10 and then dissipated to the external environment through the housing 10. This design significantly improves the heat dissipation efficiency, especially under high-load working conditions, ensuring the stable operation of the circuit board module 20.

[0181] 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 net 50. A ventilation portion 110a is provided on the housing 10, and a ventilation opening 110 is formed in the ventilation portion 110a; the battery module 30 is disposed inside the housing 10; the support net 50 is disposed on the inner side surface of the housing 10 and is attached to the ventilation portion 110a to support the ventilation portion 110a.

[0182] Thus, by providing the support net 50 on the inner side surface of the housing 10 and attaching it to the ventilation part 110a to support the ventilation part 110a, the structural strength of the ventilation part 110a can be significantly enhanced. The support net 50 can not only prevent foreign objects from entering the interior of the housing 10 through the ventilation openings 110, but also reduce the risk of cracking of the ventilation part 110a during dropping or vibration, thereby improving the safety of the ventilation part 110a. In addition, the design of the support net 50 does not affect the heat dissipation function of the ventilation openings 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.

[0183] Specifically, the support net 50 can be a protective structure provided on the inner side surface of the housing 10 for covering the ventilation openings 110. The support net 50 can be a wire mesh, a plastic net, or a net made of other materials with sufficient strength and air permeability. The support net 50 can be directly provided on the inner side surface of the housing 10 by means of adhesion or welding, or can be provided on the inner side surface of the housing 10 through other mounting structures. For example, the support net 50 can be attached to the ventilation part 110a by a sealant.

[0184] The number of the support nets 50 can correspond one-to-one to the number of the ventilation openings 110. For example, in the case of one ventilation opening 110, one support net 50 is configured. In the case of multiple ventilation openings 110, multiple support nets 50 with the same number are configured.

[0185] Please refer to Figure 24 , in some embodiments, the first housing 11 is formed with ventilation openings 110, and the support net 50 is provided on the inner side surface of the first housing 11.

[0186] Thus, when the ventilation opening 110 area or the support net 50 of the housing 10 is damaged, since the first housing 11 and the second housing 12 are detachably connected, the user can separately replace the damaged first housing 11 or the second housing 12 without needing to replace the entire housing 10. This modular design not only reduces the maintenance cost but also extends the service life of the energy storage power supply 100.

[0187] Please refer to Figure 23 and Figure 24 , in some embodiments, a limiting strip 113 is provided on the inner side surface of the first housing 11, and the limiting strip 113 and the inner side surface of the first housing 11 jointly define a second limiting groove 114, and at least a part of the support net 50 is disposed in the second limiting groove 114.

[0188] In this way, the support net 50 is fixed by the second limiting groove 114, which can effectively prevent the support net 50 from shifting or shaking in the housing 10, especially when the energy storage power supply 100 is dropped, vibrated or impacted, to ensure that the support net 50 always covers the vent 110 and maintain the protective function of the support net 50. In addition, the limiting strip 113 can also be used as a guide structure when the support net 50 is installed, so as to facilitate the rapid installation of the support net 50.

[0189] Specifically, the limiting strip 113 may be a protrusion extending away from the inner side of the first housing 11. The number of the limiting strips 113 may be multiple, for example, two, three, four or even more. The limiting strip 113 and the first housing 11 may be an integrally formed structure, which can reduce the connection gap and weak points, thereby enhancing the structural rigidity of the limiting strip 113. The limiting strip 113 and the first housing 11 may also be a split-formed structure, which can facilitate the replacement of the limiting strip 113, thereby increasing the service life of the limiting strip 113.

[0190] Please refer to Figure 23 and Figure 24 In some embodiments, there are two limit bars 113 , which are spaced apart from each other. The limit bars 113 extend from the first shell 11 toward the second shell 12 , and the support net 50 is at least partially disposed between the two limit bars 113 .

[0191] In this way, the installation position of the support net 50 can be more accurately defined by two spaced-apart limiting strips 113 , ensuring that the support net 50 will not be offset or skewed during the installation process.

[0192] The spacing arrangement and extension direction design of the two limit bars 113 make the installation of the support net 50 simpler and faster. During the installation process, the support net 50 only needs to be aligned with the gap between the two limit bars 113 and inserted. When removing, the support net 50 only needs to be taken out from between the two limit bars 113. This design not only improves the efficiency of installation and removal, but also reduces the risk of damage to the support net 50 caused by improper installation.

[0193] Specifically, the distance between the two limiting strips 113 can be adjusted according to the thickness and width of the supporting net 50 to ensure the stability of the installation.

[0194] Please refer to Figure 23 and Figure 24 In some embodiments, the support net 50 includes a mesh portion 51 and a mounting portion 52 connected to the mesh portion 51 , the mesh portion 51 is disposed in the second limiting groove 114 , and the mounting portion 52 is mounted on the first shell 11 .

[0195] In this way, the design of the installation part 52 enables the support net 50 to adapt to different structures of the housing 10. Even if the size or shape of the second limiting groove 114 of the housing 10 changes, as long as the installation part 52 can be fixed on the first outer shell 11, the support net 50 can still be used normally. This design improves the versatility and adaptability of the support net 50 and reduces the production cost.

[0196] By dividing the support net 50 into the mesh part 51 and the installation part 52, the installation of the support net 50 becomes more stable. The mesh part 51 is arranged in the second limiting groove 114 to ensure that it closely fits the ventilation opening 110, while the installation part 52 is directly fixed on 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.

[0197] Specifically, the mesh part 51 is the main part of the support net 50, usually composed of a mesh structure, and is used to cover the ventilation opening 110. The mesh part 51 allows air to flow through while preventing foreign objects from entering the interior of the housing 10 through the ventilation opening 110. The mesh part 51 can be designed in various shapes and sizes, such as a rectangular mesh, a circular mesh, or an irregularly shaped mesh, to adapt to different designs of the ventilation opening 110.

[0198] The installation part 52 is another part of the support net 50 and is used to fix the support net 50 on the first outer shell 11. The installation part 52 can be installed on the first outer shell 11 by means of bolt connection, bonding, welding, or other methods. The number of the installation parts 52 can be one or more, such as two, three, four, or even more.

[0199] Please refer to Figure 22 、 Figure 23 and Figure 24 , in some embodiments, the mesh part 51 is provided with mesh holes 51a, and the mesh holes 51a are arranged corresponding to the ventilation opening 110.

[0200] In this way, this can avoid the mesh part 51 covering the ventilation opening 110, thereby avoiding affecting the air flow at the ventilation opening 110.

[0201] Specifically, the mesh holes 51a can be designed in various shapes and sizes, such as holes with regular shapes like circular holes and square holes, or can also be holes with irregular shapes. The size and shape of the mesh holes 51a can be the same as or different from the size and shape of the ventilation opening 110.

[0202] Please refer to Figure 23 and Figure 24 , in some embodiments, the first outer shell 11 is provided with studs 115 for installing and connecting with the second outer shell 12, and the installation part 52 is sleeved on the studs 115.

[0203] Thus, by sleeving the installation part 52 on the stud 115 instead of using connecting components such as bolts or screws to connect the installation part 52 and the stud 115, the use of connecting components can be reduced, and the manufacturing cost of the energy storage power supply 100 can be lowered.

[0204] Specifically, the stud 115 can be a hollow columnar structure provided with a threaded hole. The stud 115 is a structural member arranged on the first housing 11 and is used for mounting and connecting with the second housing 12 and serving as a support for the installation part 52 of the support net 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 an independent component fixed on the first housing 11 or a part of the first housing 11.

[0205] The sleeving can be a tight fit or a loose fit, specifically depending on the installation requirements. The sleeving can be achieved through interference fit, clearance fit or transition fit.

[0206] The installation part 52 can be provided with a hole for cooperating with the stud 115, and the wall surface of the hole formed on the installation part 52 can contact the outer surface of the stud 115. The stud 115 can be provided with a threaded hole, and the threaded hole can be used for connecting 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, a bolt can be used to cooperate with the threaded hole on the stud 115, so that the head of the bolt can limit the installation part 52 to complete the fixation of the installation part 52.

[0207] 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 is formed with a ventilation opening 110. The stud 115 includes a first stud 1150 and a second stud 1151. The first stud 1150 is arranged on the first substrate 111, and the second stud 1151 is arranged on the first side plate 116. The position height of the first stud 1150 is higher than the position height of the second stud 1151. The number of the installation parts 52 is two. One installation part 52 is sleeved on the first stud 1150, and the other installation part 52 is sleeved on the second stud 1151.

[0208] Thus, if the first stud 1150 and the second stud 1151 with the same position height are set, one side of the support net 50 is likely to form a free end, thus having a tendency to separate from the inner side surface of the housing 10. By setting the first stud 1150 and the second stud 1151 with different position heights, the support net 50 can be fixed more stably, thus avoiding the support net 50 separating from the inner side surface of the housing 10 under the action of external force, and thus avoiding the support net 50 from malfunctioning.

[0209] Specifically, for the cuboid-shaped 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 substantially parallel to the horizontal plane. At this time, the position heights of the first stud 1150 and the second stud 1151 both refer to the heights of the first stud 1150 and the second stud 1151 relative to the horizontal plane.

[0210] In some embodiments, the cooling fan 212 forms an air flow flowing through the vent 110. Thus, the air flow formed by the cooling fan 212 can flow out of the housing 10 from the vent 110, thereby accelerating the air flow circulation inside and outside the housing 10, which is beneficial to improving the heat dissipation efficiency.

[0211] Please refer to Figure 1 、 Figure 25 、 Figure 26 and Figure 27 In some embodiments, the energy storage power supply 100 further includes a handle assembly 60 and a shielding member 25. The housing 10 is provided with an opening groove 14 located in the accommodation 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 on the handle 61 and the housing 10, and the handle 61 rotates relative to the housing 10 through the rotating shaft 62. One end of the rotating shaft 62 extends into the opening groove 14, the fixing member 63 is provided on the rotating shaft 62, and the fixing member 63 is located in the opening groove 14 and abuts against the groove wall of the opening groove 14 to limit the axial movement of the rotating shaft 62 relative to the housing 10; the shielding member 25 is disposed in the accommodation chamber 13 and closes the notch of the opening groove 14.

[0212] Thus, by disposing the fixing member 63 in the opening groove 14 and providing the shielding member 25 to close the notch of the opening groove 14, the accidental detachment of the fixing member 63 is prevented, the components inside the energy storage power supply 100 are protected, and the safety of the energy storage power supply 100 is improved.

[0213] Specifically, the number of the opening grooves 14 can be one or more, such as two, three, four or even more. The shape of the opening groove 14 can be set according to requirements. For example, it can be set to regular shapes such as circular or square, or can be set to irregular shapes.

[0214] The handle assembly 60 is used to facilitate the user to carry the energy storage power supply 100, and at the same time, the stability and reliability of the handle 61 are ensured through the rotating shaft 62 and the fixing member 63. The handle 61 is the part held by the user and can be made of a strong and durable material such as plastic or rubber. The handle 61 is used to facilitate the user to carry the energy storage power supply 100.

[0215] The rotating shaft 62 is a component connecting the handle 61 and the housing 10. The shape and material of the rotating shaft 62 can be selected according to requirements. For example, the rotating shaft 62 can be a cylindrical metal or plastic shaft.

[0216] The fixing member 63 is a component for fixing the rotating shaft 62, such as a snap ring 630, a nut, etc. The fixing member 63 can be an annular member made of metal or plastic. The fixing member 63 can be in direct contact with the groove wall of the opening groove 14, or in indirect contact. For example, a friction gasket can be provided between the fixing member 63 and the groove wall of the opening groove 14, and the friction gasket can abut on the two side surfaces adjacent to the fixing member 63 and the groove wall of the opening groove 14. In this way, the friction gasket can avoid the friction between the fixing member 63 and the groove wall of the opening groove 14, thereby prolonging the service life of the fixing member 63.

[0217] The shielding member 25 is a component for closing the notch of the opening groove 14, and can be a plate-shaped, sheet-shaped, mesh-shaped or other shaped structure made of materials such as metal, plastic or rubber. The shielding member 25 is used to prevent the fixing member 63 from coming out and protect the components inside the opening groove 14 from external foreign objects.

[0218] Please refer to Figure 28 and Figure 29 , in some embodiments, the shielding member 25 is disposed on the circuit board module 20.

[0219] In this way, the shielding member 25 is disposed 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 and is more vulnerable to external interference, the setting of the shielding member 25 can effectively prevent the influence of external factors on the circuit board module 20 and improve the reliability of the circuit board module 20.

[0220] Specifically, the shielding member 25 is installed on the circuit board module 20 by mechanical fixing, bonding or other means. The shielding member 25 can be directly connected to the circuit board module 20. For example, it can be fixed to the circuit board module 20 by screws, buckles, glue, etc.; it can also be connected to the inner wall of the housing 10 to be suspended on the circuit board module 20.

[0221] Please refer to Figure 27 , in some embodiments, the fixing member 63 includes a snap ring 630 having a bayonet 631 in the circumferential direction, and the snap ring 630 is clamped on the rotating shaft 62.

[0222] In this way, the fixing member 63 is designed with a snap ring 630 having a bayonet 631 in the circumferential direction, and the snap ring 630 is clamped on the rotating shaft 62, which can effectively limit the axial movement of the rotating shaft 62, thereby improving the stability of the fixing member 63 and preventing it from loosening or falling off during use.

[0223] Specifically, the snap ring 630 realizes the axial fixation of the rotating shaft 62 through the cooperation of its bayonet 631 with the rotating shaft 62. Due to the existence of the bayonet 631, the snap ring 630 can be elastically deformed, and the elastic deformation of the snap ring 630 enables the snap ring 630 to be conveniently installed and disassembled. The snap ring 630 can be designed into various types, such as shaft snap rings 630, hole snap rings 630, etc., to adapt to different installation positions and fixation requirements.

[0224] The bayonet 631 can be one or more grooves. The bayonet 631 is used to cooperate with the corresponding structure on the rotating shaft 62 and is elastically deformed and snapped into the groove of the rotating shaft 62 to achieve fixation. The bayonet 631 can be designed to be evenly distributed or non-uniformly distributed to adapt to different diameters of the rotating shaft 62 and fixation requirements. The shape of the bayonet 631 can be circular, square or other suitable shapes.

[0225] Please refer to Figure 29 , in some embodiments, the housing 10 is provided with a transfer hole 15, the rotating shaft 62 is inserted into the transfer hole 15, and the handle assembly 60 further includes a damping member 64 sleeved on the rotating shaft 62. The damping member 64 is located in the transfer hole 15 and contacts the hole wall of the transfer hole 15.

[0226] In this way, the setting of the damping member 64 can provide a certain resistance, so that the handle 61 will not be too loose when rotating, thereby controlling the rotation speed and force of the handle 61 and improving the operation stability of the energy storage power supply 100. Moreover, the resistance provided by the damping member 64 can make the handle 61 have a certain sense of damping when rotating, enhancing the user experience when operating the handle 61 and making the operation smoother and more controllable.

[0227] Specifically, the transfer hole 15 is a hole on the housing 10 for inserting the rotating shaft 62. The transfer hole 15 provides an installation position for the rotating shaft 62 and, through cooperation with the damping member 64, ensures the stability of the rotating shaft 62 and the damping effect of rotation. The shape and size of the transfer hole 15 can be adjusted according to the specific designs of the rotating shaft 62 and the damping member 64 to ensure the best cooperation effect. The transfer hole 15 can be designed to be circular, elliptical or other suitable shapes.

[0228] The damping member 64 is a component for providing resistance. The damping member 64 can be made of rubber, plastic or other materials with damping characteristics. The damping member 64 provides appropriate resistance through contact with the hole wall of the transfer hole 15, controls the rotation speed and force of the handle 61, and improves the operation stability and accuracy. The damping member 64 can be designed into various types, such as damping rings, damping sleeves, etc., to adapt to different rotating shafts 62 and transfer holes 15. The material and shape of the damping member 64 can be selected according to needs to achieve different damping effects. The damping member 64 can be fixed on the rotating shaft 62 by interference fit, bonding or other means to ensure that it will not loosen or fall off during use.

[0229] 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 hole wall of the pivot hole 610 and the peripheral 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 clamped in the stop groove 620 to enable the handle 61 and the rotating shaft 62 to rotate synchronously.

[0230] In this way, by providing the stop groove 620 and the stop protrusion 611 between the hole wall of the pivot hole 610 of the handle 61 and the peripheral surface of the rotating shaft 62, the synchronous rotation between the handle 61 and the rotating shaft 62 is ensured. This design can effectively prevent the relative sliding between the handle 61 and the rotating shaft 62 and improve the reliability of operation.

[0231] Specifically, the pivot hole 610 provides an installation position for the rotating shaft 62, and through the cooperation with the rotating shaft 62, the rotation function of the handle 61 is realized. The shape and size of the pivot hole 610 can be adjusted according to the specific design of the rotating shaft 62 to ensure the best cooperation effect. The pivot hole 610 can be designed as a circular shape, an oval shape or other suitable shapes.

[0232] The stop groove 620 is a groove on the hole wall of the pivot hole 610 or the peripheral surface of the rotating shaft 62. The stop groove 620 is used to cooperate with the stop protrusion 611 to prevent the relative sliding between the handle 61 and the rotating shaft 62 and ensure synchronous rotation. The stop groove 620 can be designed in various shapes, such as circular, square, dovetail, etc., to meet different fixing requirements. The depth and width of the stop groove 620 can be adjusted according to actual needs.

[0233] The stop protrusion 611 is a protrusion on the hole wall of the pivot hole 610 or the peripheral surface of the rotating shaft 62. The stop protrusion 611 is used to cooperate with the stop groove 620 to prevent the relative sliding between the handle 61 and the rotating shaft 62 and ensure synchronous rotation. The stop protrusion 611 can be designed in various shapes, such as circular, square, dovetail, etc., to meet different fixing requirements. The height and width of the stop protrusion 611 can be adjusted according to actual needs.

[0234] Please refer to Figure 25 and Figure 27 In some embodiments, the handle 61 is disposed on the first housing 11, and the first housing 11 is provided with an opening groove 14.

[0235] Thus, during the assembly process, the handle 61 and the first housing 11 can be assembled first, and then the whole can be connected to the second housing 12. This step-by-step assembly method can improve the assembly efficiency and reduce assembly errors. Moreover, both the handle 61 and the opening slot 14 are provided on the first housing 11, which can reduce the manufacturing complexity of the handle assembly 60 and improve the manufacturing efficiency.

[0236] Please refer to Figure 25 and Figure 27 , in some embodiments, the first side plate 116 is connected to the second housing 12. The inner surface of the first substrate 111 is provided with a surrounding wall 1110 that encloses the opening slot 14, and the handle 61 is provided on the first substrate 111.

[0237] Thus, the surrounding wall 1110 not only provides structural support for the opening slot 14 but also plays a certain protective role, preventing external objects from directly hitting the rotating shaft 62 and the fixing member 63 in the opening slot 14, thereby protecting the components located inside the opening slot 14.

[0238] Specifically, the surrounding wall 1110 can be provided on the inner surface of the first substrate 111 by mechanical fixing means, such as the surrounding wall 1110 is provided on the inner surface of the first substrate 111 by means of bolt connection, bonding or snap connection; the surrounding wall 1110 and the first substrate 111 can also be an integrally formed structure, which can reduce connection gaps and weak points, thereby enhancing the structural rigidity of the surrounding wall 1110.

[0239] The handle 61 can be provided on the first substrate 111 through the rotating shaft 62, or rather, the handle 61 rotates relative to the first substrate 111 through the rotating shaft 62.

[0240] Please refer to Figure 30 , in some embodiments, the rotating shaft 62 is provided with at least one weight-reducing groove 621.

[0241] 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 thus improving the portability of the energy storage power supply 100.

[0242] Specifically, the weight-reducing groove 621 can be designed in various shapes and sizes, such as rectangular, semi-circular, trapezoidal, etc., to meet different weight reduction and heat dissipation requirements. The depth and width of the weight-reducing groove 621 can be adjusted according to actual needs. The number of weight-reducing grooves 621 can be one, two, three or even more.

[0243] The weight reduction groove 621 can be formed by machining methods such as turning or drilling. The weight reduction groove 621 can also be formed by mold forming. For example, for the plastic rotating shaft 62, the weight reduction groove 621 can be directly formed during the injection molding process through the design of the injection mold.

[0244] Please refer to Figure 33 、 Figure 34 and Figure 35 In some embodiments, the energy storage power supply 100 further includes a sliding button 80 and an elastic pressing member 90. The housing 10 is provided with an assembly hole 16; the sliding button 80 is slidably installed in the assembly hole 16; the elastic pressing member 90 is disposed within the housing 10 and presses against the sliding button 80.

[0245] In this way, the presence of the elastic pressing member 90 can provide a uniform elastic force, so that the sliding button 80 is always subjected to a stable pressing force during the toggling process. This design can effectively reduce the poor feel when operating the sliding button 80 during toggling, make the toggling force more uniform, so that the user will not feel an obvious paragraph difference or uneven resistance during operation, thereby reducing the risk of misoperation caused by uneven force, and thus improving the feel when the user operates.

[0246] Specifically, the assembly hole 16 provides an installation position for the sliding button 80 and limits the movement trajectory of the sliding button 80, enabling the sliding button 80 to slide within the housing 10. The shape and size of the assembly hole 16 can be designed according to the shape and size of the sliding button 80. For example, it can be a linear hole, a curved hole or other types of holes, etc. The surface of the assembly hole 16 can be smoothed to reduce the friction force of the sliding button 80 during the sliding process.

[0247] The sliding button 80 is a slidable mechanical component used to control the switch or function switching of the energy storage power supply 100. The sliding button 80 can be driven to slide along the path defined by the assembly hole 16. The sliding button 80 can be made of plastic or metal materials, etc., to meet different usage requirements.

[0248] The elastic pressing member 90 is an elastic component used to provide a stable pressing force. The elastic pressing member 90 can be made of a variety of elastic materials, such as plastic, rubber or silica gel, etc.

[0249] Please refer to Figure 35 In some embodiments, the elastic pressing member 90 includes a main body 91 and an elastic arm 92 provided on the main body 91. The main body 91 is installed on the housing 10, and the elastic arm 92 presses against the sliding button 80.

[0250] In this way, the elastic pressing member 90 is provided with two parts, namely, a main body 91 and an elastic arm 92, wherein the main body 91 is mounted on the housing 10, and the elastic arm 92 directly presses the sliding button 80. This enables the elastic arm 92 to more accurately control the distribution of the pressing force, thereby further improving the uniformity of the force during the sliding button 80 is moved. The elastic deformation of the elastic arm 92 can dynamically adjust the pressing force, thereby reducing the poor hand feel when operating the sliding button 80 due to structural gaps or changes in friction.

[0251] Specifically, the body 91 and the elastic arm 92 can be connected by mechanical fixing, such as bonding, welding or clamping. The body 91 and the elastic arm 92 can also be an integrally formed structure, which can reduce the connection gap and weak points, thereby improving the overall structural rigidity of the elastic pressing member 90. The body 91 can be installed on the housing 10 by bonding, welding or threaded connection.

[0252] The elastic arm 92 can be made of a variety of elastic materials, such as spring steel, rubber, silicone, etc. The shape and size of the elastic arm 92 can be designed according to actual needs, for example, it can be corrugated, spring-shaped, sheet-shaped, etc.

[0253] 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 that the sliding button 80 feels smooth when being pushed, reducing the situation of poor feel when operating the sliding button 80, thereby improving the user experience.

[0254] Please refer to Figure 35 In some embodiments, the body 91 is frame-shaped and has a hollow hole 910 , and both ends of the elastic arm 92 are connected to the hole wall of the hollow hole 910 .

[0255] Thus, the body 91 of the elastic pressing member 90 is frame-shaped and provided with a hollow hole 910, and the two ends of the elastic arm 92 are connected to the hole wall of the hollow hole 910. This design makes the deformation of the elastic arm 92 more concentrated and stable when subjected to force, thereby further optimizing the uniformity of the force during the sliding button 80 is toggled. The presence of the hollow hole 910 can make the deformation of the elastic arm 92 more uniform, reduce local stress concentration, and further improve the poor hand feel when operating the sliding button 80.

[0256] Specifically, the body 91 is a component with a frame structure, and may be a rectangular, square or other polygonal ring structure.

[0257] The hollow hole 910 is one or more openings on the body 91, which are used to connect the elastic arm 92 and optimize the deformation distribution. The presence of the hollow hole 910 can reduce the use of materials and reduce weight, while allowing the two ends of the elastic arm 92 to be connected to the hole wall, so that the deformation of the elastic arm 92 when subjected to force is more concentrated and uniform. The shape and size of the hollow hole 910 can be designed according to actual needs, for example, it can be round, square, oval, etc. The number of hollow holes 910 can also be adjusted as needed, for example, it can be one or more, such as two, three, four or even more.

[0258] The two ends of the elastic arm 92 can be connected to the hole wall of the hollow hole 910 by bonding, threading, plugging or other methods.

[0259] Please refer to Figure 35 In some embodiments, the elastic arm 92 is corrugated and has a trough portion 920 , and the trough portion 920 presses the sliding button 80 .

[0260] In this way, the corrugated structure makes the elastic arm 92 deform more evenly when subjected to force, and the trough 920 can provide a more stable pressure, thereby further improving the uniformity of the force during the sliding button 80. This design can effectively reduce the poor hand feel when operating the sliding button 80, make the force of the sliding more uniform, and significantly improve the user experience.

[0261] Specifically, the trough 920 is the low point in the corrugated elastic arm 92, and is located at the concave part of the corrugation. The trough 920 directly presses the sliding button 80, and provides a uniform pressing force through its position and shape. The design of the trough 920 can ensure that the deformation of the elastic arm 92 when subjected to force is more concentrated and stable, thereby reducing the situation of poor hand feeling when operating the sliding button 80 and improving the user's operating feel.

[0262] Please refer to Figure 35 In some embodiments, a support platform 17 is provided on the inner surface of the shell 10 , and the body 91 rests on the support platform 17 .

[0263] Thus, the inner surface of the housing 10 is provided with a support platform 17, and the body 91 of the elastic pressing member 90 abuts against the support platform 17. This design provides an additional support point for the elastic pressing member 90, making the elastic pressing member 90 more firmly installed in the housing 10, and further improving the stability of the overall structure of the elastic pressing member 90.

[0264] Specifically, the inner surface is the side of the interior of the housing 10 facing the internal components of the energy storage power supply 100. The support platform 17 is a raised structure on the inner surface of the housing 10 for supporting the body 91 of the elastic pressing member 90. The support platform 17 can be integrally formed with the inner surface of the housing 10 or connected to the inner surface of the housing 10 by mechanical fixing means such as bonding, bolt connection or snap connection. The number of support platforms 17 can be one or more, such as two, three, four or even more. The support platform 17 can have different shapes and sizes, and can be regular shapes such as circular, square, rectangular, etc., or irregular shapes.

[0265] Please refer to Figure 35 , in some embodiments, the elastic pressing member 90 includes two protrusions 93 provided on the body 91, the two protrusions 93 are spaced apart, and the support platform 17 is clamped between the two protrusions 93.

[0266] In this way, the spaced arrangement of the two protrusions 93 enables the support platform 17 to be precisely clamped in the middle. This structure can ensure the accurate positioning of the elastic pressing member 90 during installation, reduce the installation error, and improve the assembly efficiency. In addition, the elastic pressing member 90 includes two spaced protrusions 93, and the support platform 17 is clamped between the two protrusions 93. This design provides more stable support for the elastic pressing member 90, ensuring that the elastic pressing member 90 will not shift or shake within the housing 10, thereby further enhancing the stability of the overall structure.

[0267] The protrusion 93 is a protruding part on the body 91 of the elastic pressing member 90 for cooperating with the support platform 17 to provide stable support and positioning. The protrusion 93 can have different shapes and sizes, such as circular, square, rectangular, etc. The protrusion 93 can be integrally formed with the body 91 of the elastic pressing member 90 or can be a separate component fixed to the body 91 by means such as welding or bonding.

[0268] The clamping of the support platform 17 can be achieved in different ways, such as direct clamping, clamping through an intermediate component, etc. The clamping force can be controlled by adjusting the shape and size of the protrusion 93.

[0269] 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, and the mounting post 18 is inserted into the through hole 911.

[0270] In this way, during the production process, the elastic pressing member 90 can be first fixed to the housing 10 through the cooperation of the mounting post 18 and the through hole 911 to form a pre-assembled component. In this way, when assembling with other components subsequently, this pre-assembled component can be directly used, greatly improving the assembly efficiency and convenience.

[0271] Specifically, the through hole 911 is a through hole on the body 91 of the elastic pressing member 90 for inserting 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, oval, 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.

[0272] The mounting post 18 is a protruding structure on the housing 10 for inserting into the through hole 911 to achieve the fixation of the elastic pressing member 90. The mounting post 18 can have different shapes and sizes, such as circular, square, strip-shaped, etc. The number of mounting posts 18 can be adapted to the number of through holes 911. The mounting post 18 can be integrally formed with the housing 10 or can be a separate component and is fixed to the housing 10 by welding, bonding or other means.

[0273] Please refer to Figure 35 、 Figure 36 and Figure 37 In some embodiments, the elastic pressing member 90 includes a pressing block 94 provided on the side of the body 91 facing away from the sliding button 80. The elastic pressing member 90 is clamped between the housing 10 and the circuit board module 20, and the pressing block 94 abuts against the circuit board module 20.

[0274] In this way, by the pressing block 94 abutting against the circuit board module 20, the elastic pressing member 90 is stably clamped between the housing 10 and the circuit board module 20. This design can ensure that the elastic pressing member 90 does not shift or shake within the housing 10, thus ensuring its stable pressing effect on the sliding button 80. Moreover, in this way, the circuit board module 20 can be used to press the elastic pressing member 90 without the need to provide other additional components, which can not only improve the space utilization rate within the housing 10 but also reduce the manufacturing cost.

[0275] Specifically, the pressing block 94 is a protruding part on the body 91 of the elastic pressing member 90 for contacting the circuit board module 20 and providing a force. The pressing block 94 can have different shapes and sizes, such as circular, square, strip-shaped, etc.

[0276] Clamping means that the elastic pressing member 90 is clamped between the housing 10 and the circuit board module 20 and is fixed by the pressure between the two.

[0277] Please refer to Figure 37 In some embodiments, both the sliding button 80 and the circuit board module 20 are provided on the first housing 11.

[0278] In this way, both the sliding button 80 and the circuit board module 20 are arranged on the first housing 11, making the assembly process simpler. During assembly, the sliding button 80 and the circuit board module 20 can be first installed on the first housing 11 and then connected to the second housing 12, reducing the complexity of the assembly steps and improving the assembly efficiency.

[0279] Specifically, the sliding button 80 and the circuit board module 20 can be arranged on the first housing 11 by means of bolt connection, snap connection or bonding.

[0280] Please refer to Figure 35 , in some embodiments, the body 91 of the elastic pressing member 90 is fixed to the housing 10 by a fastener.

[0281] In this way, by fixing the body 91 of the elastic pressing member 90 to the housing 10 with a fastener, the stability of the elastic pressing member 90 installed in the housing 10 can be ensured. The use of the fastener can prevent the elastic pressing member 90 from shifting or loosening during use, thus ensuring its stable pressing effect on the sliding button 80.

[0282] Specifically, the fastener can include bolts, screws, nuts or rivets, etc. Corresponding threaded holes or riveting holes and other structures can be provided on the housing 10. The number of fasteners can be one or more, such as two, three, four or even more.

[0283] Please refer to Figure 5 、 Figure 6 and Figure 7 , the energy storage power supply 100 according to the embodiment of the present invention includes a first housing assembly 103 and a second housing assembly 104. The first housing assembly 103 includes a first housing 11 and a circuit board module 20 fixed on the first housing 11; the second housing assembly 104 includes a second housing 12 and a battery module 30 fixedly installed on the second housing 12. Among them, the first housing 11 and the second housing 12 are detachably connected and enclose an accommodation chamber 13, and both the circuit board module 20 and the battery module 30 are located in the accommodation chamber 13.

[0284] In this way, the modular design of the first housing assembly 103 and the second housing assembly 104 allows the circuit board module 20 and the battery module 30 to be assembled separately and then installed integrally, which simplifies the overall assembly process and improves the assembly efficiency.
