Description

Technical Field

[0001] This utility model relates to the field of energy storage, and more specifically, to an energy storage system. Background Technology

[0002] With the increasing popularity of green energy, the demand for photovoltaic systems and corresponding energy storage batteries is gradually increasing, especially in home settings. The sunlight from balconies is converted into electricity and stored in energy storage devices. However, the energy storage needs of different families are not uniform. For scenarios with high demand, multiple energy storage batteries are usually stacked. In related technologies, floor mats are used for stacking. However, if the ground is uneven, the batteries are prone to tipping over under external force, posing a certain safety risk. Utility Model Content

[0003] In order to solve or improve the technical problem that the above-mentioned energy storage devices are prone to tipping over when stacked, one objective of this utility model is to provide an energy storage system.

[0004] To achieve the above objectives, the first aspect of this utility model provides an energy storage system, comprising: an integrated energy storage unit and at least one power supply pack, wherein the integrated energy storage unit and at least one power supply pack are detachably connected; a sliding guide rail and a sliding guide groove extending along a first direction, the shape of the sliding guide groove being adapted to the shape of the sliding guide rail; wherein, when the power supply pack is connected to the integrated energy storage unit, the power supply pack is located below the integrated energy storage unit, one of the sliding guide rail and the sliding guide groove is located on the mounting bottom wall of the integrated energy storage unit, and the other is located on the mounting top wall of the power supply pack; or when multiple power supply packs are connected, one of the sliding guide rail and the sliding guide groove is located on the mounting bottom wall of one of the two connected power supply packs, and the other is located on the mounting top wall of the other of the two connected power supply packs.

[0005] The energy storage system provided by this utility model includes an integrated energy storage unit and one or more power packs. By setting a sliding guide rail and sliding guide groove connection structure between the integrated energy storage unit and the power packs, or between multiple power packs, stable stacking and detachable connection of the energy storage system are achieved. The sliding guide rail and sliding guide groove are shape-matched, ensuring precise sliding positioning of the power packs and the integrated energy storage unit in a first direction, or precise sliding positioning of multiple power packs in a first direction, preventing relative misalignment and tilting, thereby making the stacked structure more stable.

[0006] Of course, the interlocking structure of the sliding guide rail and the sliding guide groove can maintain their relative positions under the action of external forces, avoiding collapse caused by the shift of the center of gravity when stacking high-rise buildings.

[0007] In the above technical solution, the sliding guide rail protrudes from the mounting base wall, which is the base wall of one of the energy storage units or power packs equipped with the sliding guide rail.

[0008] In the above technical solution, the integrated energy storage unit includes a battery casing and a heat dissipation casing arranged and connected along a first direction; wherein, a sliding guide rail is provided in the mounting base wall corresponding to the battery casing.

[0009] In the above technical solution, a limiting wall is provided at one end of the sliding guide groove in the first direction. When the power supply pack is connected to the energy storage unit or multiple power supply packs are connected, the limiting wall abuts against one end of the sliding guide rail.

[0010] In the above technical solution, the wall surface of one end of the power supply in the first direction is provided with an assembly port, which is connected to the sliding guide groove, and the shape of the assembly port is adapted to the cross-sectional shape of the sliding guide rail.

[0011] In the above technical solution, the sliding guide rail specifically includes: a connecting strip connected to the mounting base wall; and a support plate located at the end of the connecting strip away from the mounting base wall; wherein the projection of the support plate on the mounting base wall covers the projection of the connecting strip on the mounting base wall.

[0012] In the above technical solution, the bottom wall of the support plate is a plane, and the bottom wall of the support plate is parallel to the mounting bottom wall.

[0013] In the above technical solution, the sliding guide rail is detachably connected to the integrated energy storage unit, or the sliding guide rail is detachably connected to the power supply pack.

[0014] The above technical solution also includes: a foot pad structure, which is disposed on the mounting base wall; wherein, the surface of the end of the sliding guide rail away from the mounting base wall is lower than the surface of the end of the foot pad structure away from the mounting base wall.

[0015] In the above technical solution, there are two sliding guide rails on the mounting base wall, and the two sliding guide rails are spaced apart on the mounting base wall along the second direction. Attached Figure Description

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0020] In related technologies, balcony photovoltaic systems typically use a stacking method with foot pads. If the ground is uneven or the number of stacked layers is high, there is a risk of collapse due to external forces. This application presents a novel sliding rail stacking structure, which makes the stacking more stable and can avoid the risk of collapse.

[0021] Overall, current balcony photovoltaic energy storage products often use a foot pad stacking structure when stacked. When the ground is uneven or the number of stacked layers is high, the contact area between the foot pad and the ground is small, resulting in insufficient stability and easy tipping over under external force, posing a safety hazard.

[0022] This solution proposes a sliding rail stacking structure with a sliding rail component at the bottom, which serves as both a positioning structure for stacking and a large-area foot pad. The upper and lower stacking units are precisely aligned via the sliding rail structure, ensuring minimal positional shift during stacking and improving overall stability. The bottom sliding rail structure has a significantly larger contact area with the ground than traditional foot pads, better distributing pressure, adapting to minor unevenness in the ground, and reducing the risk of tilting. Because the upper and lower units are interlocked via the sliding rails, they are less prone to slippage or tipping under external forces, making it particularly suitable for high-rise stacking applications in confined spaces such as balconies.

[0023] The sliding rail structure increases the contact area with the ground, making stacking and placement more stable. This effectively solves the problem of traditional foot-mounted stackers easily tipping over on uneven ground or when stacked at high levels. It improves product safety and user experience, reducing damage and safety hazards caused by unstable stacking.

[0024] The following reference Figures 1 to 5 This invention describes an energy storage system provided according to some embodiments of the present invention.

[0025] like Figure 1 and Figure 2 As shown, embodiments of this application provide an energy storage system 100. By setting a cooperative connection structure of sliding guide rails 106 and sliding guide grooves 108 between the integrated energy storage unit 102 and the power supply pack 104, or between multiple power supply packs 104, stable stacking and detachable connection of the energy storage system 100 are achieved. The shapes of the sliding guide rails 106 and sliding guide grooves 108 are adapted to each other, ensuring precise sliding positioning of the power supply pack 104 and the integrated energy storage unit 102 in the first direction, preventing relative misalignment and tilting, thus making the stacked structure more stable. Furthermore, since the sliding guide rails 106 protrude from the mounting base of the integrated energy storage unit 102, they form a larger contact surface than traditional foot pads, distributing weight, adapting to uneven ground, and reducing the risk of tipping. The interlocking structure of the sliding guide rails 106 and sliding guide grooves 108 can maintain their relative positions under external forces, preventing collapse due to center of gravity shift during high-level stacking.

[0026] Specifically, the energy storage system 100 includes an integrated energy storage unit 102 and one or more power packs 104. In addition, it is equipped with sliding guide rails 106 and sliding guide grooves 108 on the integrated energy storage unit 102 and the power packs 104. The integrated energy storage unit 102 is located at the top of the entire energy storage system 100 and is the main energy storage and control unit, providing energy storage functions and serving as the base for connection with the power packs 104. When assembling the integrated energy storage unit 102 and the power packs 104, or when assembling multiple power packs 104, sliding guide rails 106 can be provided on the mounting bottom wall of the corresponding structure for sliding engagement with another single structure, such as the power pack 104, providing upper weight and stable support for the stacked structure. The bottom sliding guide rails 106 securely connect the integrated energy storage unit 102 to the power pack 104, improving overall stability.

[0027] The power pack 104 is detachably connected to the energy storage unit 102, and when the two are connected, it is located below the energy storage unit 102. The power pack 104 mainly provides additional power support or functional expansion for the energy storage unit 102. At the same time, as the bottom support unit of the energy storage unit 102, the power pack 104 forms an integrated stacked unit through a sliding connection with the energy storage unit 102. When the bottom contacts the ground, it plays a role in stable support.

[0028] Optionally, the sliding guide rail 106 is disposed on the mounting bottom wall of the energy storage unit 102 along the first direction of the energy storage unit 102, and the sliding guide groove 108 is disposed on the mounting top wall of the power supply unit 104 along the first direction of the power supply unit 104.

[0029] Optionally, the sliding guide groove 108 is disposed on the mounting bottom wall of the energy storage unit 102 along the first direction of the energy storage unit 102, and the sliding guide rail 106 is disposed on the mounting top wall of the power supply unit 104 along the first direction of the power supply unit 104.

[0030] Optionally, the sliding guide rail 106 is disposed on the mounting bottom wall of the power supply package 104 along the first direction of the power supply package 104, and the sliding guide groove 108 is disposed on the mounting top wall of the other power supply package 104 along the first direction of the other power supply package 104.

[0031] Optionally, the sliding guide groove 108 is disposed on the mounting bottom wall of the power supply pack 104 along the first direction of the power supply pack 104, and the sliding guide rail 106 is disposed on the mounting top wall of the other power supply pack 104 along the first direction of the other power supply pack 104.

[0032] The mounting top wall is the top wall of one of the sliding guide rails 106 or sliding guide grooves 108 in the energy storage unit 102 or the power supply pack 104.

[0033] In some embodiments, the sliding guide rail 106 may optionally protrude from the mounting base wall of the integrated energy storage unit 102. For example, the sliding guide rail 106 serves as a sliding connection element between the integrated energy storage unit 102 and the power supply pack 104, cooperating with the sliding guide groove 108 on the power supply pack 104 to achieve sliding installation and positioning along the first direction. It can be understood that the protruding design of the sliding guide rail 106 increases the contact area with the power supply pack 104. When the integrated energy storage unit 102 is placed directly on the ground without the power supply pack 104, the sliding guide rail 106 also increases the contact area with the ground, improving stability. It can be understood that the cooperation of the sliding guide rail 106 and the sliding guide groove 108 ensures that the power supply pack 104 slides smoothly into the first direction during installation, avoiding misalignment. Simultaneously, the sliding guide rail 106 forms a fitted structure after connection, resisting lateral displacement and tilting.

[0034] The sliding guide groove 108 is provided on the mounting top wall of the power pack 104 along the first direction. Its shape is adapted to the shape of the sliding guide rail 106. The sliding guide groove 108 serves as the connection interface between the power pack 104 and the energy storage unit 102. It cooperates with the sliding guide rail 106 to realize sliding installation along the first direction.

[0035] Similarly, the sliding guide rail 106 and the sliding guide groove 108 are respectively set on the mounting top wall and mounting bottom wall of different single-unit structures, and the above-mentioned similar effects exist, which will not be described in detail here.

[0036] The shape of the sliding guide groove 108 matches the shape of the sliding guide rail 106, ensuring a stable connection without shaking. Users can complete the installation or disassembly simply by sliding along the first direction. After installation, the mating structure of the sliding guide groove 108 and the sliding guide rail 106 can withstand vertical and horizontal forces, preventing displacement caused by external forces.

[0037] The sliding guide rail 106 protrudes downward relative to the mounting bottom wall of the energy storage unit 102, which can increase the contact depth between the sliding guide rail 106 and the power supply pack 104 and improve the connection strength. At the same time, when the energy storage unit 102 is used alone, the protruding part is at the bottom, which can increase the contact area with the ground, thereby dispersing pressure and improving stability.

[0038] It should be emphasized that this solution can effectively avoid the risk of tipping over caused by the small contact area of ​​traditional foot pad stacking, adapt to slightly uneven ground, and make the entire energy storage system 100 more stable when stacked or placed.

[0039] The sliding guide rail 106 is fixed to the mounting base wall of the integrated energy storage unit 102 along the first direction and protrudes from the mounting base wall. The sliding guide groove 108 is fixed to the mounting top wall of the power supply pack 104 along the first direction, and its shape matches the sliding guide rail 106. The sliding guide rail 106 and the sliding guide groove 108 achieve a fitting connection by sliding along the first direction, preventing relative misalignment and tilting after connection. Finally, the integrated energy storage unit 102 is located above the power supply pack 104, and the two form an integrated energy storage system 100 after connection.

[0040] In some embodiments, optionally, such as Figure 3 As shown, the integrated energy storage unit 102 includes a battery casing 1022 and a heat dissipation casing 1024. The integrated energy storage unit 102 is located above the energy storage system 100, and is formed by connecting the battery casing 1022 and the heat dissipation casing 1024 along a first direction to create a unified structure. The structure is clearly partitioned, facilitating functional arrangement. The battery casing 1022 is located at one end of the integrated energy storage unit 102 and is connected to the heat dissipation casing 1024 along the first direction. The battery casing 1022 is used to store and fix the energy storage battery. By setting the sliding guide rail 106 on the mounting bottom wall of the battery casing 1022 (i.e., the part of the mounting bottom wall corresponding to the battery casing), the weight is concentrated near the sliding guide rail 106, maintaining the center of gravity and improving stacking stability. The heat dissipation casing 1024 is connected to the battery casing 1022 along the first direction and is located at one end of the battery casing 1022. The heat dissipation casing 1024 houses control circuits, management modules, etc., used to monitor and regulate the operating status of the energy storage system 100. The heat dissipation housing 1024 is connected to the battery housing 1022 to form an integrated energy storage unit 102, which facilitates internal wiring and signal transmission while maintaining the compactness of the overall structure.

[0041] It is understandable that, since the battery casing 1022 is a weight-concentrated area, placing the sliding guide rail 106 on the mounting bottom wall of the battery casing 1022 can reduce the force deviation at the connection and prevent tilting.

[0042] In summary, by placing the sliding guide rail 106 on the mounting bottom wall of the battery casing 1022, and connecting the battery casing 1022 and the heat dissipation casing 1024 along the first direction, the rationality of the functional zoning of the integrated energy storage unit 102 is ensured, and the connection part is close to the center of gravity, improving the stability of the sliding connection. With the protruding sliding guide rail 106 and the matching sliding guide groove 108, the overall stacked structure remains stable even on uneven ground or when the stacking height is high, avoiding the risk of tipping over, while also facilitating installation and disassembly.

[0043] The energy storage system 100 achieves stable stacking, increased contact area, and anti-tipping effects through the detachable sliding connection between the integrated energy storage unit 102 and the power pack 104. The newly added battery casing 1022 and heat dissipation casing 1024 are connected along the first direction, making the functional zoning of the integrated energy storage unit 102 clearer and the installation and layout more reasonable, while maintaining the stability and precision of the sliding connection.

[0044] In some embodiments, optionally, a limiting wall 1082 is provided at one end of the sliding guide groove 108 in the first direction. The limiting wall 1082 abuts against one end of the sliding guide rail 106, thereby achieving reliable positioning and stable connection between the power supply pack 104 and the energy storage unit 102. The limiting wall 1082 effectively prevents the power supply pack 104 from shifting beyond the end of the sliding guide rail 106 in the first direction after installation, avoiding loosening or detachment of the connection.

[0045] Specifically, the limiting wall 1082 is located at one end of the sliding guide groove 108 along the first direction, at the end of the sliding guide groove 108 on the mounting top wall of the power pack 104. The limiting wall 1082 restricts the maximum range of sliding of the power pack 104 along the first direction, preventing the power pack 104 from continuing to slide out of the end of the sliding guide rail 106 after installation. When the power pack 104 is connected to the energy storage unit 102, the limiting wall 1082 abuts against one end of the sliding guide rail 106, forming a physical barrier to ensure a stable connection.

[0046] Under the action of the limiting wall 1082, the power supply 104 can be effectively prevented from slipping and falling off due to vibration, external force or uneven ground. At the same time, during installation, the sliding guide groove 108 slides in along the sliding guide rail 106 until the limiting wall 1082 abuts against the end of the sliding guide rail 106, automatically forming the installation endpoint position, simplifying the installation operation.

[0047] In summary, by providing a limiting wall 1082 at one end of the sliding guide groove 108, the power pack 104 can abut against the end of the sliding guide rail 106 through the limiting wall 1082 after installation, forming a physical stop structure, which greatly improves the connection stability and safety of the energy storage system 100. Furthermore, the reasonable layout of the battery casing 1022 and the heat dissipation casing 1024, along with the structure of the sliding guide rail 106 protruding from the mounting base of the battery casing 1022, effectively avoids the risk of tipping over due to small contact area and unstable stacking in traditional foot pad stacking, making it suitable for high-rise stacking of balcony photovoltaic energy storage products and placement on uneven ground.

[0048] In some embodiments, optionally, such as Figure 4 As shown, by setting the assembly port 1042 on the wall of the power supply package 104, the assembly port 1042 provides a channel for the sliding guide rail 106 to enter the interior of the power supply package 104, allowing the sliding guide rail 106 to be smoothly embedded in the sliding guide groove 108, completing a stable sliding connection. The assembly port 1042 is connected to the sliding guide groove 108, ensuring smooth guidance and positioning of the sliding guide rail 106 during the assembly process. The shape of the assembly port 1042 is adapted to the cross-sectional shape of the sliding guide rail 106, ensuring that the sliding guide rail 106 can fit tightly, avoiding loosening or displacement, and improving the stability and safety of the connection.

[0049] Specifically, the assembly port 1042 is located on the wall surface of one end of the power supply package 104 in the first direction and is connected to the sliding guide groove 108, providing an assembly channel for the sliding guide rail 106 to enter the sliding guide groove 108. Through a design that adapts to the cross-sectional shape of the sliding guide rail 106, the sliding guide rail 106 can be smoothly embedded and tightly fitted. It can be understood that the assembly port 1042 simplifies the assembly process and ensures that the sliding guide rail 106 can smoothly enter the sliding guide groove 108 during assembly, avoiding jamming.

[0050] Assembly port 1042 is connected to sliding guide groove 108 to form a continuous guide path for sliding guide rail 106, guiding sliding guide rail 106 to correctly enter sliding guide groove 108, forming a complete sliding connection channel, ensuring smooth installation, avoiding assembly errors, and improving assembly efficiency and product consistency.

[0051] In summary, this solution uses the assembly port 1042 as a guide channel for the sliding guide rail 106 to enter the sliding guide groove 108, ensuring the matching accuracy and tightness of the sliding guide rail 106 and the sliding guide groove 108, and improving the ease of assembly and connection stability.

[0052] In some embodiments, optionally, such as Figure 5As shown, the sliding guide rail 106 mainly includes a connecting strip 1062 and a support plate 1064. The connecting strip 1062 is the basic component of the sliding guide rail 106, directly connected to the mounting base wall of any single-unit structure, such as the energy storage unit 102 or the power supply pack 104. The connecting strip 1062 is fixed to the mounting base wall, undertaking the installation and load-bearing tasks of the sliding guide rail 106. As the main structure of the sliding guide rail 106, the connecting strip 1062 provides a fixed connection between the sliding guide rail 106 and the energy storage unit 102 or the power supply pack 104, transmitting and distributing the forces borne by the sliding guide rail 106, ensuring that the sliding guide rail 106 is stable and does not shift.

[0053] Optionally, the support plate 1064 is disposed at the end of the connecting strip 1062 away from the mounting bottom wall, serving as an extended support surface for the sliding guide rail 106. It can be understood that the support plate 1064 is located at the outer end of the connecting strip 1062, forming a relatively large support area, expanding the contact area between the sliding guide rail 106 and the sliding guide groove 108 of the power supply package 104, providing additional load-bearing and support capabilities, and enhancing the overall structural strength of the sliding guide rail 106.

[0054] By limiting the projection of the support plate 1064 on the mounting base wall of the energy storage unit 102 to cover the projection of the connecting strip 1062, a wide base structure is formed, which significantly improves the stability and load-bearing capacity of the sliding guide rail 106 and effectively prevents the sliding guide rail 106 from being deformed or damaged due to torque or pressure during use.

[0055] The projected area of ​​the support plate 1064 on the mounting base of the energy storage unit 102 is larger than and covers the projected area of ​​the connecting strip 1062 on the mounting base of the energy storage unit 102, so as to achieve uniform distribution of force, avoid local stress concentration, and improve the bonding strength and durability between the sliding guide rail 106 and the energy storage unit 102.

[0056] In summary, the connecting strip 1062 serves as the fixed base for the sliding guide rail 106, ensuring its secure installation on the mounting base of the integrated energy storage unit 102. The support plate 1064, located at the distal end of the connecting strip 1062, forms a wide support surface whose projection covers the projection of the connecting strip 1062, significantly improving the structure's stability and load-bearing capacity. This design effectively distributes stress, prevents localized stress concentration, and enhances the overall safety and durability of the energy storage system 100.

[0057] In some embodiments, optionally, a support plate 1064 is disposed at the end of the connecting strip 1062 away from the mounting base wall, forming the bearing and support surface of the sliding guide rail 106. Based on this, by restricting the bottom wall of the support plate 1064 to be a plane, and the bottom wall of the support plate 1064 being parallel to the mounting base wall of the energy storage unit 102, it is ensured that the support surface of the sliding guide rail 106 and the mounting base wall are on the same plane in the same direction. Thus, the planar and parallel bottom wall design enables the support plate 1064 to form a uniform and stable contact or projection relationship with the mounting base wall, reducing uneven force caused by angular deviation, ensuring that the sliding guide rail 106 is evenly distributed under vertical and horizontal loads, and improving the stability and durability of the structure.

[0058] Optionally, the projection of the support plate 1064 on the mounting base wall covers the projection of the connecting strip 1062. Combined with the parallel feature of the base wall, this further ensures the maximization of the force-bearing area and the uniform transmission of force.

[0059] In summary, the bottom wall of the support plate 1064 is flat and parallel to the mounting bottom wall, which ensures that the force-bearing surface of the sliding guide rail 106 is flat and the force is uniform, avoiding structural stress concentration or instability caused by angular deviation, improving the overall stability and load-bearing capacity of the sliding guide rail 106, and enhancing the resistance of the stacked structure of the energy storage system 100 to external forces in actual use.

[0060] Furthermore, the planar and parallel design also facilitates manufacturing and assembly, improving product consistency and quality control.

[0061] In some embodiments, the sliding guide rail 106 can be detachably connected to the energy storage unit 102 or the power supply pack 104 via a specific detachable connection structure, facilitating assembly and maintenance. The specific detachable connection structure can employ bolts, nuts, clips, pins, quick-release clips, or other mechanical connectors. These connectors are positioned between the connecting rail 1062 and the mounting base wall, allowing for disassembly and reinstallation as needed. Alternatively, sliding grooves, spring clips, or other structures can be used to achieve quick assembly and disassembly.

[0062] For example, the connecting strip 1062 is fixed to the mounting base wall by bolts or quick-release clips, and the support plate 1064 is combined with the connecting strip 1062. The support plate 1064 can be disassembled by clips or bolts for easy maintenance and replacement.

[0063] The detachable connection allows for quick assembly and disassembly of the sliding guide 106 during production, transportation, and maintenance, reducing the difficulty of assembly and disassembly. It also facilitates the replacement or maintenance of the sliding guide 106 and related structural components. After disassembly, it is easy to clean dust or impurities from inside the sliding guide 106, extending its service life.

[0064] In summary, by detachably connecting the sliding rail 106 to the installed unit structure, such as the energy storage unit 102 or the power pack 104, the flexibility and maintainability of the structure can be enhanced. This ensures that while maintaining a stable connection, it is convenient for users to disassemble, maintain, and replace parts, which is beneficial for the long-term use of the product and its application in multiple scenarios.

[0065] In some embodiments, optionally, the foot pad structure 110 is disposed on the mounting base wall, typically distributed at multiple locations on the mounting base wall, for contact with the ground. The foot pad structure 110 serves as a buffer and support between the energy storage unit 102 or power pack 104 and the ground, improving overall stability. The foot pad structure 110 can distribute weight, reducing local pressure on the ground. In addition, the foot pad structure 110 provides anti-slip and shock-absorbing functions, reducing the risk of sliding or tipping on uneven ground.

[0066] One end of the sliding guide rail 106 is away from the mounting base wall (i.e., the part of the connecting strip 1062 with the support plate 1064 at its far end). The surface of the far end is lower than the surface of the foot pad structure 110 at the end away from the mounting base wall. The surface height of the far end of the sliding guide rail 106 is lower than the surface height of the far end of the foot pad structure 110. That is, the far end of the sliding guide rail 106 is lower than the foot pad. When placed on the ground, the far end of the sliding guide rail 106 contacts the ground first.

[0067] As an important component that supports the power pack 104 and its connection, the sliding guide rail 106 contacts the ground first, which can better bear and transmit the weight and external force from the power pack 104, making the connection structure between the power pack 104 and the energy storage unit 102 stable and reducing shaking caused by uneven ground.

[0068] The foot pad structure 110 serves as an auxiliary support and anti-slip function, but it does not bear the weight first. The foot pad structure 110 can provide auxiliary support when the sliding guide rail 106 has poor contact with the ground, preventing the energy storage unit 102 from shaking as a whole.

[0069] In summary, the sliding guide rail 106 contacts the ground first, ensuring that the connecting parts are directly stressed and effectively preventing the power pack 104 from sliding or falling off. The foot pads serve as auxiliary support, providing additional anti-slip and vibration cushioning, thus improving overall safety. Together, they enhance the overall stability and safety of the energy storage unit 102 and the power pack 104.

[0070] In some embodiments, optionally, two sliding guide rails 106 are provided on the mounting base wall. The two sliding guide rails 106 are spaced apart along the second direction of the energy storage unit 102, that is, the two sliding guide rails 106 are parallel to each other and separated by a certain distance in the second direction.

[0071] Optionally, the two sliding guides 106 are symmetrically distributed to share the load and improve overall stability.

[0072] The two sliding guide rails 106 jointly bear the support and connection force of the energy storage unit 102 or the power pack 104, disperse the load, reduce the stress concentration of a single guide rail, improve the structural strength and durability, and enhance stability: the double guide rails are arranged at intervals to effectively prevent the power pack 104 from swaying and tilting in the second direction, and enhance the overall rigidity of the stacking system.

[0073] Optionally, the two sliding guide rails 106 cooperate with the two sliding guide grooves 108 corresponding to the power supply package 104 to ensure that the power supply package 104 is accurately slidably installed in the first direction without lateral offset. In addition, the double-rail structure enhances the firmness and reliability of the connection and reduces the risk of loosening or falling off due to external force or vibration.

[0074] In summary, the two sliding guide rails 106 are spaced apart along the second direction, which optimizes the force distribution and avoids deformation or damage caused by excessive load on a single guide rail. The dual guide rail structure effectively suppresses the lateral movement and swaying of the energy storage system 100 in the second direction, improving the stability and safety of the stacked structure. Combined with the dual guide rail design of the sliding guide groove 108, the installation and sliding of the power pack 104 is smoother and more precise, facilitating quick assembly and disassembly.

[0075] In some embodiments, optionally, such as Figure 5 As shown, an anti-slip pad 112 is provided on the far end bottom wall surface of the sliding guide rail 106 to serve as a contact pad with the ground. Optionally, the anti-slip pad 112 can be made of rubber, silicone or other materials with anti-slip properties.

[0076] Optionally, the anti-slip mat 112 can be a flat mat, a textured surface, or an anti-slip pattern to enhance the coefficient of friction.

[0077] Of course, the anti-slip mat 112 can be designed according to the bottom wall area of ​​the sliding guide rail 106 to ensure that the contact area is sufficiently anti-slip.

[0078] The anti-slip pad 112 can be connected to the sliding guide rail 106 by means of bolts, nuts, clips, pins or adhesive. For example, the anti-slip pad 112 has a hole at the bottom, and the fixing hole on the bottom wall of the sliding guide rail 106 is passed through it and fixed with bolts. Alternatively, quick-release clips or spring clips can be used for easy and quick disassembly.

[0079] The anti-slip pad 112 can significantly improve the friction coefficient when the sliding guide rail 106 contacts the ground, preventing slippage or slipping during stacking or movement. It can also buffer external vibrations and impacts, protecting the structure of the sliding guide rail 106 and the energy storage unit 102.
