[0032] Please see Figure 1 , Figure 1 This is an exploded three-dimensional structural diagram of the energy storage power supply 100 according to an embodiment of the present invention. The energy storage power supply 100 of this application embodiment includes a housing 10 and a battery module 20. The housing 10 has different first sidewalls 11 and second sidewalls 12. The battery module 20 includes a bracket 21 and a battery 22 disposed on the bracket 21. The bracket 21 is provided with a first mounting portion 211 and a second mounting portion 212 disposed at a distance from the first mounting portion 211. The first mounting portion 211 is fastened to the first sidewall 11, and the second mounting portion 212 is fastened to the second sidewall 12.

[0033] The energy storage power supply 100 of this application embodiment is fastened to the first side wall 11 by the first mounting part 211 and fastened to the second side wall 12 by the second mounting part 212, so that the battery module 20 can be connected to different side walls of the housing 10. The force on the battery module 20 is in different directions and positions, which makes the connection of the battery module 20 more secure. When the energy storage power supply 100 is dropped or collided, the risk of the battery module 20 becoming loose or even failing is lower, which helps to improve the safety of the energy storage power supply 100 and thus improve the service life of the energy storage power supply 100.

[0034] Specifically, the housing 10 of the energy storage power supply 100 is an external structural assembly used to enclose the internal components of the energy storage power supply 100. In the embodiments of this application, the overall structure of the housing 10 is a cuboid. The housing 10, which encloses the internal components of the energy storage power supply 100, provides physical protection for the internal structure, preventing the intrusion of foreign objects and water. Simultaneously, it disperses the impact energy received by the internal structure of the energy storage power supply 100 in the event of impacts, drops, or compression, reducing deformation of the internal structure and thus preventing short circuits and other failures within the energy storage power supply 100, ensuring the normal functioning of the energy storage power supply 100. Exemplarily, the material of the housing 10 can be a low-cost engineering plastic with good insulation properties.

[0035] The first sidewall 11 of the housing 10 is a plane located at the bottom of the battery module 20, and the second sidewall 12 is a plane parallel to the side of the battery module 20 and perpendicular to the first sidewall 11. Both sidewalls, as part of the housing 10, possess sufficient strength and rigidity. When the energy storage power supply 100 is impacted or dropped, the first sidewall 11 and the second sidewall 12 can withstand some of the external impact, providing protection for the internal components such as the battery module 20. Furthermore, the housing 10 also serves as a mounting base for the internal structure of the energy storage power supply 100, providing a reference and support for the installation of the battery module 20 and other internal structures of the energy storage power supply 100.

[0036] The battery module 20 consists of a support 21 and batteries 22. The battery 22 is the most basic unit for energy storage and can be a single electrochemical cell. Multiple batteries 22 can be mounted on the support 21 and can be fixedly connected together via a specific connection structure. Through electrochemical reactions within the multiple batteries 22, electrical energy is stored and released, serving as the energy source for the entire energy storage power supply 100. In the embodiments of this application, the batteries 22 of the energy storage power supply 100 are all cylindrical batteries 22.

[0037] The bracket 21 of the battery module 20 is a mechanical structure inside the housing 10 of the energy storage power supply 100 for fixing, housing, and protecting multiple batteries 22. The bracket 21 provides a dedicated mounting position for each battery 22, ensuring that the batteries 22 do not move or shake inside the bracket 21, ensuring that each battery 22 is in the correct position, and can absorb some of the impact and vibration energy transmitted from the housing 10 when the energy storage power supply 100 is subjected to large external forces, preventing it from being directly transmitted to the batteries 22, thus further providing physical protection for the batteries 22. For example, the bracket 21 can be a plastic bracket 21, which has a lighter weight and better insulation.

[0038] The first mounting portion 211 and the second mounting portion 212 on the bracket 21 are key components for connecting the entire battery module 20 to the housing 10. They are structural features located on the surface of the bracket 21 for fixing, connecting, and positioning. The first mounting portion 211 is securely connected to the first side wall 11, and the second mounting portion 212 is securely connected to the second side wall 12. This prevents the battery module 20 from moving relative to the first side wall 11 and the second side wall 12, essentially ensuring the fixed position of the battery module 20 and providing a guarantee for the connection stability inside the energy storage power supply 100.

[0039] Please refer to the following: Figure 1In some embodiments, the first mounting portion 211 protrudes from the surface of the bracket 21, the first sidewall 11 is provided with a first through hole 111, the first mounting portion 211 is provided with a first stud 2111, the first stud 2111 is aligned with the first through hole 111, and the energy storage power supply 100 includes a first fastener 30, the first fastener 30 passes through the first through hole 111 and is tightened with the first stud 2111 to fasten the bracket 21 and the housing 10.

[0040] In the above embodiment, the first fastener 30 connects the first mounting part 211 to the first side wall 11, thereby fastening the bracket 21 to the first side wall 11, and then fastening the battery module 20 as a whole to the first side wall 11. This ensures that the relative position between the bottom of the battery module 20 and the first side wall 11 remains basically unchanged, thus providing a guarantee for the stable connection of the battery module 20 to the housing 10.

[0041] Specifically, the first through hole 111 is a hole that completely penetrates from one side of the first sidewall 11 to the other side of the first sidewall 11. The size and shape of the first through hole 111 match the first fastener 30. The diameter of the first through hole 111 is slightly larger than the diameter of the rod of the first fastener 30, so that the first fastener 30 can be accommodated and allowed to easily pass through the first through hole 111, avoiding assembly failure due to minor machining errors.

[0042] The first fastener 30 is a mechanical part used to securely connect the first through hole 111 and the first mounting part 211 into a whole. The first fastener 30 can be a highly standardized part, thus giving it strong interchangeability and versatility. For example, the first fastener 30 can be a bolt. The connection formed between the first fastener 30 and the first through hole 111 is a detachable connection, allowing for multiple assembly and disassembly without damaging the first through hole 111, which is beneficial for the installation and maintenance of the energy storage power supply 100. The inner wall of the first through hole 111 is relatively smooth. In cooperation with the first fastener 30, it fixes the first side wall 11 to the first mounting part 211, basically restricting the movement of the bottom of the battery module 20 relative to the first side wall 11 in all degrees of freedom. This achieves a fixed connection between the battery module 20 and the housing 10 on the first side wall 11, ensuring the reliability of the connection and providing a guarantee for the functional realization of the energy storage power supply 100.

[0043] Please see Figure 1 and Figure 2 , Figure 2This is a side view of the bracket 21 according to an embodiment of the present invention. In some embodiments, the second sidewall 12 is provided with a second stud 121, the second mounting part 212 is provided with a second through hole 2121, the second through hole 2121 is aligned with the second stud 121, and the energy storage power supply 100 includes a second fastener 40, which passes through the second through hole 2121 and is tightened with the second stud 121 to secure the bracket 21 and the housing 10.

[0044] In the above embodiment, the second fastener 40 connects the second stud 121 on the second sidewall 12 to the second mounting part 212 on the bracket 21, thereby fastening the bracket 21 to the second sidewall 12, and then fastening the battery module 20 to the second sidewall 12 as a whole. This ensures that the relative position of the battery module 20 and the second sidewall 12 does not change significantly, thus providing a guarantee for the fixed connection of the battery module 20 on the housing 10.

[0045] Specifically, the second through hole 2121 is a through hole penetrating the second mounting portion 212. In the embodiments of this application, the second mounting portion 212 is located on the side of the bracket 21 near the second sidewall 12, and there are two of them, located at the front and rear sides of the bracket 21 respectively. The second stud 121 on the second sidewall 12 is correspondingly positioned to the second mounting portion 212. The second fastener 40 can be a connecting component similar to or the same as the first fastener 30. The second fastener 40 passes through the second through hole 2121 on the second mounting portion 212 and forms a fixed connection with the second stud 121. In this way, the second fastener 40 can fix the bracket 21 where the second mounting portion 212 is located to the second sidewall 12 where the second stud 121 is located, so that the movement of the bracket 21 on the second sidewall 12 is further restricted, ensuring the stability of the bracket 21 within the housing 10.

[0046] Furthermore, when the energy storage battery is subjected to an impact, the impact on the casing 10 can be transmitted to the bracket 21 through the second mounting part 212, which avoids the impact acting directly on the fragile solder joints or connection points inside the energy storage power supply 100. This is beneficial to improving the impact resistance of the energy storage power supply 100 and extending its service life.

[0047] Please refer to the following: Figure 1 and Figure 3 , Figure 3 This is a schematic diagram of the first sidewall 11 after the shell 10 is connected according to an embodiment of the present invention. In some embodiments, the first mounting part 211 is provided with a limiting rib 2112, the first sidewall 11 is provided with a first limiting part 112, the first limiting part 112 is provided with a first limiting groove 1121, and the limiting rib 2112 is engaged in the first limiting groove 1121.

[0048] In the above embodiment, the cooperation between the limiting rib 2112 and the limiting groove can provide positioning and guidance for the first stud 2111, ensuring that the first stud 2111 can smoothly enter the first through hole 111, and can prevent over-assembly of the mounting part, thereby ensuring that the first mounting part 211 is firmly fixed to the first side wall 11.

[0049] Specifically, the limiting rib 2112 is a sheet-like structure protruding from the surface of the first mounting portion 211, which can be integrally formed with the first sidewall 11. The first limiting groove 1121 is a groove formed by the first limiting portion 112 on the surface of the first sidewall 11, which cooperates with the limiting rib 2112. Its shape and size match the cooperating limiting rib 2112. In the embodiments of this application, the limiting ribs 2112 on the surface of the first mounting portion 211 are evenly distributed on the surface of the first mounting portion 211, and their positions correspond one-to-one with the positions of the first limiting grooves 1121. The thickness of the limiting rib 2112 is slightly less than the width of the first limiting groove 1121, which can ensure that the limiting rib 2112 can be smoothly inserted into the first limiting groove 1121, thus ensuring the normal realization of its limiting function.

[0050] When the first mounting part 211 is assembled with the first side wall 11, the limiting rib 2112 first enters the first limiting groove 1121 to guide the movement of the parts along the preset path and finally reach the accurate mounting position. The limiting rib 2112 of the first mounting part 211 and the first limiting groove 1121 on the first side wall 11 work together. When the limiting rib 2112 reaches the bottom of the first limiting groove 1121, the first stud 2111 can be inserted into the first through hole 111 and smoothly connected to the first mounting part 211, so that the bracket 21 is basically fixed on the first side wall 11.

[0051] Furthermore, when the energy storage power supply 100 is subjected to a large impact, the limiting rib 2112 of the first mounting part 211 can withstand part of the impact transmitted from the first side wall 11, which can enhance the rigidity and deformation resistance of the bracket 21 in this direction and further improve the safety of the battery.

[0052] Please refer to the following: Figure 1 In some embodiments, the housing 10 includes a first housing 14 and a second housing 15 detachably connected to the first housing 14. The first housing 14 and the second housing 15 together form a receiving space 16, in which the battery module 20 is received. The first housing 14 and the second housing 15 are spliced ​​together to form a first sidewall 11, and the second housing 15 forms a second sidewall 12. There are multiple first mounting parts 211, some of which are fastened to the first sidewall 11 of the first housing 14, and other parts of which are fastened to the first sidewall 11 of the second housing 15.

[0053] In the above embodiment, the receiving space 16 formed by the first housing 14 and the second housing 15 provides an installation position for the battery module 20, ensuring that the battery module 20 can be smoothly installed into the housing 10. The first housing 14 and the second housing 15 are connected to form a first sidewall 11. Part of the first sidewall 11 is located in the first housing 14 and the other part is located in the second housing 15. The first mounting part 211 is opposite to the first sidewall 11, providing a connection position for fixing the battery module 20 on the housing 10, thereby ensuring that the battery module 20 can be smoothly connected to the housing 10.

[0054] Specifically, the second housing 15 is the part of the housing 10 where the second sidewall 12 is located, and the first housing 14 is another part of the housing excluding the second housing 15. The first housing 14 and the second housing 15 are detachably connected. The first housing 14 and the second housing 15 can be combined together by a specific connection method, and can be separated and reassembled multiple times completely without permanently damaging the housing 10, which facilitates the maintenance of the internal components of the housing 10.

[0055] The accommodating space 16 is a three-dimensional area enclosed by the first housing 14 and the second housing 15 after they are connected. The size of the housing 10 is reasonably arranged according to the space occupied by the internal battery module 20 and other components to ensure that all internal components in the housing 10 can be installed correctly and do not interfere with each other. The shape and size of the accommodating space 16 correspond to the space occupied by the internal components, which is conducive to improving the structural compactness of the energy storage power supply 100.

[0056] A portion of the first sidewall 11 is located on the first housing 14, and another portion is located on the second housing 15. A plurality of first mounting portions 211 are connected to the first sidewall 11 located on the first housing 14, and the other portion is connected to the first sidewall 11 located on the second housing 15. When the first housing 14 and the second housing 15 are connected, a plurality of first through holes 111 on the first sidewall 11 form an integral whole, corresponding to the plurality of first mounting portions 211, so that the first sidewall 11 and the bracket 21 form a tight connection.

[0057] Please see Figure 1 , Figure 2 and Figure 4 , Figure 4 This is a schematic diagram of the structure of the third sidewall 13 according to an embodiment of the present invention. In some embodiments, the housing 10 has a third sidewall 13, and the first sidewall 11, the second sidewall 12 and the third sidewall 13 are all different. The bracket 21 is provided with a second limiting part 213, and the third sidewall 13 is provided with a third limiting part 131. The second limiting part 213 and the third limiting part 131 are connected in a limiting manner.

[0058] In the above embodiment, the third limiting part 131 on the third sidewall 13 is connected to the second limiting part 213 on the bracket 21, so that the bracket 21 and the third sidewall 13 are connected together, which further ensures the stable connection between the battery module 20 and the housing 10, and can further improve the collision and impact resistance of the energy storage battery.

[0059] Specifically, the third sidewall 13 is the inner surface of the housing 10 opposite to the second sidewall 12. The third sidewall 13, together with the first sidewall 11 and the second sidewall 12, forms the boundary of the accommodating space 16. The second limiting portion 213 on the bracket 21 is a partial structure on the side of the bracket 21 closest to the third sidewall 13. The third limiting portion 131 is a structure located on the third sidewall 13 and protruding from the third sidewall 13 towards the bracket 21; its number and structural shape correspond to the second limiting portion 213. When the first housing 14 is connected to the bracket 21, the second limiting portion 213 and the third limiting portion 131 are connected, ensuring that the position of the bracket 21 within the housing 10 is unique and correct, avoiding assembly deviations. When the energy storage power supply 100 is subjected to external force, the connection of the limiting part can prevent the third side wall 13 and the bracket 21 from moving or rotating relative to each other under vibration and impact. The impact force will be transmitted and dispersed between the housing 10 and the bracket 21 through the mutually cooperating limiting parts, thereby improving the rigidity and reliability of the overall structure.

[0060] The second limiting part 213 and the third limiting part 131 can be connected to a predetermined position by fasteners. Before the fasteners are connected, the cooperation of the limiting parts can improve the initial fixation, keep the bracket 21 in the connected position, and facilitate subsequent fastening operations.

[0061] Please see Figure 2 and Figure 4 In some embodiments, the second limiting part 213 is provided with a second limiting groove 2131, and the third limiting part 131 has a limiting post 1311, which is inserted into the second limiting groove 2131.

[0062] In the above embodiment, the limiting post 1311 is inserted into the second limiting groove 2131, and the limiting post 1311 is connected to the second limiting groove 2131, thereby combining the third limiting part 131 with the second limiting part 213, thereby realizing the connection between the bracket 21 and the third side wall 13.

[0063] Specifically, the limiting post 1311 is a structure protruding from the component base, serving as a rigid positioning reference. It guides the mating second limiting groove 2131 to quickly reach the approximately correct position. The second limiting groove 2131 is a groove on the bracket 21 whose shape matches the limiting post 1311, acting as a receiving structure to accept the insertion of the limiting post 1311, forming a mating pair. Through the mating second limiting groove 2131, the limiting post 1311 effectively restricts the movement of the third sidewall 13 and the bracket 21 in a plane perpendicular to the axis of the limiting post 1311, thereby achieving positioning and limiting functions. When the energy storage power supply 100 is subjected to external force, the force is transmitted and dispersed through the contact between the limiting post 1311 and the inner wall of the second limiting groove 2131. For example, the limiting post 1311 can be integrally formed with the third sidewall 13, which is beneficial for improving processing efficiency.

[0064] Please see Figure 4 and Figure 5 , Figure 5 This is a partial cross-sectional view of the energy storage power supply 100 according to an embodiment of the present invention. In some embodiments, the bracket 21 is provided with a groove 214 that matches the shape of the battery, and the second limiting part 213 is disposed in the groove 214.

[0065] In the above embodiment, the groove 214 provides space for the second limiting part 213. The second limiting part 213 is located in the groove 214, which makes full use of the space occupied by the bracket 21, which is beneficial to improving the space utilization rate inside the energy storage power supply 100.

[0066] Specifically, the bracket 21 is positioned on both sides facing the second sidewall 12 and the third sidewall 13 according to the arrangement of the internal batteries. The cylindrical batteries inside the two battery modules 20 near the third sidewall 13 form a space recessed towards the batteries along their length. The bracket 21 is fitted into this space and adheres to the battery surface, forming a groove 214 on its surface. The third limiting part 131 connects to the second limiting part 213 at the groove 214, ensuring the bracket 21 is stably connected to the third sidewall 13, further improving the structural stability of the energy storage power supply 100. Simultaneously, the groove 214 is positioned on the surface of the bracket 21 corresponding to the connection points of the batteries at two different heights, fully utilizing the space occupied by the bracket 21, improving space utilization, and facilitating control of the battery module 20's dimensions.

[0067] Please refer to the following: Figure 1 and Figure 6 , Figure 6 This is a schematic diagram of the support plate 50 according to an embodiment of the present invention. In some embodiments, the energy storage power supply 100 further includes the support plate 50 and an inverter 60 fixed on the support plate 50. The support plate 50 is fixedly connected to the bracket 21 and is located between the inverter 60 and the bracket 21.

[0068] In the above embodiment, the support plate 50 can connect the battery module 20 and the inverter 60 into a whole. When assembling the energy storage power supply 100, the battery module 20 and the inverter 60 can be pre-installed so that they can be installed as a whole. This makes the assembly of the energy storage power supply 100 more convenient and helps to speed up the assembly efficiency of the energy storage power supply 100.

[0069] Specifically, the inverter 60 of the energy storage power supply 100 is the core power conversion module that converts the DC power from the battery 22 into AC power. The support plate 50 is located above the battery module 20 and is fixed inside the housing 10. The support plate 50 has a large planar area and a certain thickness, which is used to install and support the planar structure of the inverter 60. The upper surface of the support plate 50 provides a stable and reliable mounting and support plane for the inverter 60. The inverter 60 is fastened to the support plate 50, and the lower surface of the support plate 50 is fixedly connected to the bracket 21, so that the bracket 21 can be fixed to the support plate 50.

[0070] Please refer to the following: Figure 7 , Figure 7 This is an exploded view of the internal structure of the energy storage power supply 100 according to an embodiment of this utility model. In the embodiment of this application, the support plate 50 has four third through holes 511 located at the four corners of the support plate 50. The bracket 21 includes a third mounting part 215, which is located above the bracket 21. There are four third mounting parts 215, which correspond one-to-one with the four third through holes 511 on the support plate 50. Exemplarily, the third mounting parts 215 and the third through holes 511 are connected together by fasteners, thereby fixing the support plate 50 and the bracket 21 together. The inverter 60, which is located on the support plate 50 and fixed to the support plate 50, and the battery module 20 are fixedly connected as a whole. The inverter 60 and the battery module 20 can be installed as a whole on the housing 10, which makes the assembly method simpler, greatly improves the assembly efficiency of the energy storage power supply 100 assembly process, helps to save operation time, and thus reduces production costs.

[0071] Please refer to the following: Figure 1 and Figure 6 In some embodiments, the support plate 50 includes a flat plate portion 51 and a bent portion 52 connected to the edge of the flat plate portion 51. The inverter 60 and the bracket 21 are both fixedly connected to the flat plate portion 51, and the bent portion 52 is fastened to the second side wall 12.

[0072] In the above embodiment, the flat plate portion 51 of the support plate 50 is used to fix the inverter 60 and the connecting bracket 21. The bent portion 52 of the support plate 50 is fixedly connected to the second side wall 12, and the support plate 50 is fastened to the second side wall 12, thereby fastening the support plate 50 to the housing 10, further ensuring the stability of the bracket 21 and the inverter 60 relative to the housing 10.

[0073] Specifically, the flat plate portion 51 is the main functional surface of the support plate 50. Its surface is flat and it is a plate-like structure with a large width-to-thickness ratio. The inverter 60 is fixed to the flat plate portion 51 of the support plate 50. The flat plate portion 51 provides a mounting position for the inverter 60 and improves the stability of the inverter 60 within the housing 10. The bent portion 52 of the support plate 50 is a portion that is bent vertically from the edge of the flat plate portion 51 towards the bracket 21. In the embodiment of this application, there are two bent portions 52, located at opposite ends of the flat plate portion 51 on the side closest to the second sidewall 12 of the housing 10.

[0074] The bending portion 52 has a fourth through hole 521. The energy storage power supply 100 also includes a third fastener 70. The fourth through hole 521 of the bending portion 52 is fastened to the second side wall 12 through the third fastener 70, thereby fastening the support plate 50 where the bending portion 52 is located to the second side wall 12 together. This, in turn, connects the inverter 60 and the battery module 20 connected to the support plate 50 to the outer casing where the second side wall 12 is located, forming a multi-directional constraint on the inside of the energy storage power supply 100. This greatly restricts the movement of the inverter 60 and the battery module 20 relative to the casing 10, further improving the connection stability inside the energy storage power supply 100.

[0075] Furthermore, the bending structure of the bending portion 52 can effectively prevent deformation of the support plate 50 that may be caused by the weight of the inverter 60 or installation stress. When the energy storage power supply 100 is subjected to a large external force, since the support plate 50 is connected to the housing 10 by the bending portion 52, the stress generated by drops, impacts, etc., can be more evenly distributed to a larger area and more connection points. This avoids excessive concentration of stress on the support plate 50 at the third through hole 511 of the flat plate portion 51, reduces the possibility of damage to the connection points on the flat plate portion 51, and further improves the safety of the energy storage power supply 100.
