Description

Technical Field

[0001] This application belongs to the field of energy storage power technology, specifically relating to an anti-tipping energy storage device. Background Technology

[0002] As a traditional power supply method, mains power has the characteristics of stable power supply and strong dispatchability, and can provide continuous and reliable power support for various electrical equipment. However, relying entirely on mains power not only faces problems such as high energy consumption and environmental pollution, but also may lead to power shortages and voltage fluctuations during peak electricity consumption periods, affecting power quality.

[0003] The emergence of energy storage devices provides an effective technical solution to the aforementioned problems. Energy storage devices have peak-shaving and valley-filling functions. Specifically, they absorb and store electrical energy during periods of low load and release it to supply the system during periods of peak load, effectively eliminating the peak-valley difference between day and night. In this way, energy storage devices can improve the reliability and stability of the power system, optimize the allocation of power resources, reduce dependence on traditional grid power, and reduce energy consumption and environmental pollution. This is of great significance for promoting the optimization and upgrading of the energy structure and sustainable development.

[0004] To facilitate installation and expandability, energy storage products typically employ a stacked modular design. When a large number of batteries are stacked, the center of gravity of the energy storage batteries becomes relatively high, resulting in poor stability. They are prone to tipping over when subjected to external impacts or minor earthquakes, causing battery damage, affecting normal user operation, and potentially posing a safety hazard. Utility Model Content

[0005] One of the objectives of this application is to provide an anti-tipping energy storage device that can prevent the energy storage device from tipping over.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application discloses an anti-tipping energy storage device, comprising: a main package, wherein a first battery module and an inverter are disposed within the main package, the first battery module and the inverter being arranged along a first direction; a power supply package, disposed below the bottom of the main package; a second battery module is disposed within the power supply package, the second battery module being electrically connected to the first battery module; the power supply package includes a first side and a second side, the first side and the second side being disposed opposite to each other along the first direction; at least two limiting fasteners are respectively disposed on the first side and the second side of the power supply package; each limiting fastener includes a first fixing part and a second fixing part; the first fixing part is used to fix to the power supply package and is detachably connected to the power supply package, and the second fixing part is used to fix to the surface to be installed.

[0008] In the above technical solution, the energy storage device is limited by the connection between the limiting fastener and the surface to be installed (such as a wall), thereby preventing the energy storage device from tipping over without increasing the weight at the bottom.

[0009] In some technical solutions, optionally, the power-on pack includes multiple sub-power-on packs; the multiple sub-power-on packs are stacked along a second direction, which intersects with the first direction. This allows for flexible adjustment of the power-on pack's capacity to meet the usage requirements of different application scenarios.

[0010] In some technical solutions, optionally, at least two limiting and fixing components are located in the same sub-energizer. This creates a direct mechanical transmission path, facilitating installation.

[0011] In some technical solutions, optionally, at least two limiting fasteners are located in the sub-powered package adjacent to the main package. This improves the anti-tipping effect and reduces the material strength requirements for the limiting fasteners and the sub-powered package.

[0012] In some technical solutions, optionally, at least two limiting and fixing components are respectively set in different sub-energizers. This can avoid stress concentration.

[0013] In some technical solutions, the anti-tipping energy storage device may optionally include a first connector; wherein, the first fixing part is provided with a first mounting hole, and the power supply unit is provided with a fixing hole; the first connector passes through the first mounting hole and extends into the fixing hole, and the first connector and the fixing hole are threadedly connected. The threaded connection method is not easy to loosen, and the structure is simple and easy to disassemble.

[0014] In some technical solutions, optionally, the first connector includes: a base; a first connecting segment disposed on the base and coaxially arranged with the base, wherein the cross-sectional dimension of the first connecting segment is smaller than the cross-sectional dimension of the base; the first connecting segment passes through the first mounting hole and extends into the fixing hole, and is threadedly connected to the fixing hole. This prevents loosening.

[0015] In some technical solutions, optionally, the first connector further includes: a second connecting section, located on the side of the first connecting section away from the base, coaxially arranged with the first connecting section, and the diameter of the second connecting section being smaller than the diameter of the first connecting section; wherein, the first fixing part is provided with a slot, the slot communicating with the first mounting hole, and the width of the slot being greater than the diameter of the second connecting section but smaller than the diameter of the first connecting section; the fixing hole and the second connecting section are threadedly connected, or the fixing hole and the first connecting section are threadedly connected. Thus, a single bolt can be used for multiple purposes, meeting the needs of multiple connection specifications.

[0016] In some technical solutions, optionally, there are multiple slots, which are spaced apart circumferentially along the first mounting hole. This eliminates the need for directional alignment, thus facilitating installation.

[0017] In some technical solutions, the anti-tipping energy storage device may optionally include a second connector, a second mounting hole on the second fixing part, and the second connector passing through the second mounting hole and being connected and fixed to the surface to be installed.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0030] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] The following is combined Figures 1 to 9 The anti-tipping energy storage device provided in this application will be described in detail through specific embodiments and application scenarios.

[0032] It should be noted that in the embodiments of this application, the first direction is the horizontal direction or the front-back direction of the energy storage device, and the second direction is the vertical direction or the up-down direction of the energy storage device.

[0033] Reference Figure 1 and Figure 2 Some embodiments of this application provide an anti-tipping energy storage device, the structure of which includes: a main package 100, a power supply package 110, and a limiting and fixing component 120.

[0034] Reference Figure 1 and Figure 3 Specifically, the main package 100, as the core component of the energy storage device, can store a large amount of electrical energy and release it stably when needed. It includes a first battery module 101 and an inverter 102, which are arranged along a first direction. The first battery module 101 is used to store electrical energy, and the inverter 102 is electrically connected to the first battery module 101 to convert the electrical energy converted from solar energy from direct current to alternating current to meet the power needs of different devices.

[0035] Reference Figure 2 and Figure 4The power pack 110 is located below the bottom of the main pack 100 and includes a second battery module 111. The second battery module 111 is electrically connected to the first battery module 101. The power pack 110 serves as a supplementary mechanism to the main pack 100, expanding its capacity. For example, if the main pack 100 has a capacity of 2 kWh, stacking a power pack 110 with the same capacity of 2 kWh will result in an energy storage system with a capacity of 4 kWh. The power pack 110 also includes a first side 112 and a second side 113, which are arranged opposite each other along a first direction.

[0036] Reference Figure 1 and Figure 6 There are at least two limiting and fixing members 120, which are respectively disposed on the first side 112 and the second side 113. Each limiting and fixing member 120 includes a first fixing part 121 and a second fixing part 122. The first fixing part 121 is used to fix to the power supply 110 and is detachably connected to the power supply 110. The second fixing part 122 is used to fix to the surface to be installed 130.

[0037] In the above embodiment, the main package 100, as the core component of the energy storage device, is responsible for energy storage and release. Compared to the power supply package 110, the main package 100 is heavier. Therefore, when stacked, the higher the energy storage device is, the more prone it is to tipping over. Thus, by connecting the limiting fastener 120 to the mounting surface 130 (such as a wall), the energy storage device is limited, preventing it from tipping over without increasing the weight at the bottom. Its simple structure and convenient installation and disassembly provide a solid and reliable safety guarantee for the energy storage device during operation, ensuring its safe and stable operation. Furthermore, the limiting fastener 120 is detachable, allowing it to be manufactured and used independently as an accessory, and users can select the appropriate limiting fastener 120 according to their actual environment.

[0038] Reference Figures 7 to 9 In some embodiments, the power-on package 110 includes a plurality of sub-power-on packages 114, which are stacked along a second direction, and the second direction intersects (e.g., perpendicular to) the first direction.

[0039] In practical applications, the capacity of the power-on pack 110 can be flexibly adjusted by increasing or decreasing the number of stacked sub-power-on packs 114 to meet the usage requirements of different application scenarios.

[0040] Reference Figure 7 and Figure 8 In some embodiments, at least two limiting fasteners 120 may be disposed on the same sub-power-on package 114 or on different sub-power-on packages 114.

[0041] In the above embodiment, the limiting fasteners 120 are fixed to the same sub-energizing package 114, and the fixing force of the two limiting fasteners 120 acts on the same sub-energizing package 114, which can form a more direct mechanical transmission path. However, if the stress is too concentrated and the material strength of the sub-energizing package 114 is insufficient, long-term stress may lead to local deformation and affect the overall structural stability. Therefore, in order to disperse the stress, the limiting fasteners 120 can be set on different sub-energizing packages 114. In this way, the fixing force can be distributed to multiple sub-energizing packages 114, reducing the risk of stress concentration in a single component.

[0042] In some embodiments, at least two limiting fasteners 120 are disposed on the sub-powered package 114 which is directly adjacent to the main package 100.

[0043] In practical applications, the main package 100, as the core part of the energy storage device, is relatively heavy. Therefore, the limiting and fixing component 120 is arranged on the sub-powered package 114, which is directly adjacent to the main package 100. Compared with the arrangement at the far end, the constraint force required to prevent tipping is smaller, so the anti-tipping effect is better. Moreover, since the constraint force is smaller, the strength requirement is lower, so the material strength requirements of the limiting and fixing component 120 and the sub-powered package 114 can be reduced.

[0044] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments, the anti-tipping energy storage device further includes a first connector 140 for connecting the first fixing part 121 and the power supply unit 110. Specifically, the first fixing part 121 has a first mounting hole 1211, and the power supply unit 110 has a fixing hole 1101. The first connector 140 passes through the first mounting hole 1211 and extends into the fixing hole 1101, and is threadedly connected to the fixing hole 1101. The first connector 140 and the fixing hole 1101 are connected by threads, which makes it less prone to loosening, and the structure is simple and easy to disassemble.

[0045] It is understood that, in addition to threaded connections, other detachable structures such as locating pins or snap-fit ​​structures can also be used for connection, and this embodiment is not limited to this.

[0046] In the above embodiment, the first connector 140 includes a base 141 and a first connecting segment 142. The first connecting segment 142 is disposed on the base 141 and coaxially disposed with the base 141, and the cross-sectional dimension of the first connecting segment 142 is smaller than the cross-sectional dimension of the base, that is, the projected area of ​​the first connecting segment 142 on the base 141 is within the range of the base 141; the first connecting segment 142 passes through the first mounting hole 1211 and extends into the fixing hole 1101 and is threadedly connected to the fixing hole 1101.

[0047] In practical applications, the projection of the first connecting segment 142 onto the base 141 must be completely within the range of the base 141 to ensure that the base 141 completely covers the first connecting segment 142. This can increase the contact area with the first fixing part 121 and prevent the base 141 from sinking into the hole, thereby preventing loosening.

[0048] In some embodiments, the first connector 140 further includes a second connecting segment 143, which is disposed on the side of the first connecting segment 142 away from the base 141 and is coaxially arranged with the first connecting segment 142; the diameter of the second connecting segment 143 is smaller than the diameter of the first connecting segment 142; the fixing hole 1101 and the second connecting segment 143 are threadedly connected, or the fixing hole 1101 and the first connecting segment 142 are threadedly connected.

[0049] In the above embodiments, the first connector 140 adopts a stepped shaft segment design, which can be used for fixing holes 1101 with different diameters, realize one bolt for multiple uses, meet the connection requirements of multiple specifications, and thus help reduce costs.

[0050] Reference Figure 2 and Figure 6 In practical applications, the first fixing part 121 is provided with a slot 1212, which communicates with the first mounting hole 1211. The width of the slot 1212 is greater than the diameter of the second connecting section 143 but smaller than the diameter of the first connecting section 142. Thus, when the second connecting section 143 is threaded, the first connecting member 140 can slide into the slot 1212, allowing the second connecting section 143 to pass through it. The first connecting section 142, however, is restricted by the slot 1212 and cannot pass through, forming a mechanical stop. This ensures that the first connecting member 140 remains firmly pressed, thereby guaranteeing connection reliability without increasing costs.

[0051] In some embodiments, there are multiple slots 1212, which are spaced apart circumferentially along the first mounting hole 1211. In this way, the first connector 140 can slide into any position of the slot 1212 without orientation alignment, thereby facilitating installation.

[0052] Reference Figure 2 In some embodiments, the anti-tipping energy storage device further includes a second connector 150. The second fixing part 122 has a second mounting hole 1221, and the second connector 150 passes through the second mounting hole 1221 to connect and fix to the surface to be installed 130.

[0053] The second connector 150 serves as the anchor point between the limiting and fixing component 120 and the surface to be installed 130, enabling the limiting and fixing component 120 and the surface to be installed 130 to form a stable connection system, bearing the overturning force of the entire energy storage device, thereby preventing the energy storage device from tipping over and effectively ensuring the safe and stable operation of the energy storage device.

[0054] In practical applications, the second connector 150 can be selected from different types, such as expansion bolts, self-tapping bolts, etc., depending on the type of the surface 130 to be installed (such as concrete, metal, and wood).
