Description

Technical Field

[0001] This invention relates to the field of battery energy storage technology, and more specifically, to a fixed component, a battery pack structure, and an energy storage box. Background Technology

[0002] Currently, in the field of battery energy storage, especially for large-scale energy storage systems, battery pack securing is a critical technical aspect. Battery packs typically need to be secured inside or outside the energy storage cabinet to ensure stability and safety during transportation, installation, and operation. The securing structure of the battery pack directly affects the overall performance and lifespan of the battery system, especially under harsh environments such as vibration, impact, or temperature changes, where battery pack securing is particularly important.

[0003] However, existing battery pack securing structures generally use fasteners (such as bolts and screws) directly connected to the guide rails or cabinet. While this method provides a certain level of stability, the fasteners are prone to loosening or even falling off during cabinet movement or when subjected to vibration. Loose fasteners not only reduce the effectiveness of securing the battery pack, causing it to move inside the cabinet, but may also come into contact with live components, leading to safety issues such as short circuits. Summary of the Invention

[0004] The main objective of this invention is to provide a fixing component, a battery pack structure, and an energy storage box to solve the problem that the battery pack fixing structure in the prior art is prone to loosening, resulting in low safety.

[0005] To achieve the above objectives, according to one aspect of the present invention, a fixing assembly is provided, comprising: a mounting bracket including two guide rail seats disposed opposite to each other, the two guide rail seats forming a bearing space for accommodating a component to be fixed, and a stop plate provided at one end of each guide rail seat along its length direction; two fastening components respectively disposed on the two guide rail seats at the ends opposite to the stop plates, the fastening components including a mounting member and a first limiting member and a second limiting member respectively connected to the mounting member, the mounting member being connected to the guide rail seat and the component to be fixed to fix the component; the first limiting member and the second limiting member respectively cooperating with the guide rail seat to limit the movement of the mounting member along a first direction and a second direction respectively.

[0006] Furthermore, the mounting component includes: a first mounting plate, a second mounting plate, and a third mounting plate, wherein the first mounting plate, the second mounting plate, and the third mounting plate are arranged perpendicularly to each other in pairs, and two adjacent mounting plates in the mounting component are respectively connected to the guide rail seat and the component to be fixed, and the first limiting member and the second limiting member are respectively connected to another mounting plate in the mounting component.

[0008] Furthermore, the first bending plate is made of plastic material, and the end of the first limiting plate away from the first bending plate is provided with a first stop. The bottom surface of the bottom plate of the guide rail seat is provided with a first mounting protrusion, so that after the first limiting groove is engaged with the bottom plate of the guide rail seat, the first limiting plate drives the first stop to move to abut against the side of the first mounting protrusion away from the first bending plate.

[0009] Furthermore, the first mounting plate has a second side that is interconnected with the first side. The second limiting member includes: a second bent plate connected to the second side; and a second limiting plate connected to the second bent plate. The second limiting plate, the second bent plate, and the outer wall surface of the first mounting plate form a second limiting groove. The second limiting groove is engaged with the bottom plate of the guide rail seat to limit the movement of the mounting member in the second direction.

[0010] Furthermore, the second bending plate is made of plastic material, and the end of the second limiting plate away from the second bending plate is provided with a second stop. The bottom surface of the bottom plate of the guide rail seat is provided with a second mounting protrusion, so that after the second limiting groove is engaged with the bottom plate of the guide rail seat, the second limiting plate drives the second stop to move to abut against the side of the second mounting protrusion away from the second bending plate.

[0011] Furthermore, the side plate of the guide rail base is provided with a plurality of first mounting holes, and the second mounting plate is provided with a plurality of first connecting holes. The plurality of first mounting holes and the plurality of first connecting holes are arranged in a one-to-one correspondence, so that the first connecting component is respectively passed through the first connecting hole and the first mounting hole, so that the second mounting plate is relatively fixed to the guide rail base.

[0012] Furthermore, the housing of the component to be fixed is provided with multiple second mounting holes, and the third mounting plate is provided with multiple second connecting holes. The multiple second mounting holes and the multiple second connecting holes are arranged in a one-to-one correspondence, so that the second connecting components are respectively passed through the second connecting holes and the second mounting holes, so that the third mounting plate is relatively fixed to the component to be fixed.

[0013] According to another aspect of the present invention, a battery pack structure is provided, comprising: the aforementioned fixing component; and a battery pack mounted within the carrying space of the fixing component.

[0014] According to another aspect of the present invention, an energy storage box is provided, comprising: a cluster support, including at least one receiving space for accommodating a battery pack structure, wherein each receiving space is provided with a first support and a second support disposed opposite to each other; at least one of the aforementioned battery pack structures, wherein two guide rail seats of each battery pack structure are respectively fixed on the first support and the second support within the receiving space.

[0016] In this way, after the mounting component is connected to the guide rail and the component to be fixed to secure it, the first and second limiting components respectively limit the movement of the mounting component along the first and second directions. This significantly reduces the shaking and displacement of the component to be fixed within the load-bearing space and the loosening of the mounting component during transportation. Compared with traditional fasteners, the fixing component in this application, through the cooperation of the first and second limiting components with the guide rail, can maintain a tight state even under long-term vibration or temperature change environments, preventing the mounting component from loosening and falling off, ensuring the safe fixing of the battery pack and other components, and thus solving the problem of low safety caused by the easy loosening of the battery pack fixing structure in the prior art. Furthermore, through the cooperation of the first and second limiting components with the guide rail, even if the mounting component is loose, the component to be fixed can still be fixed, avoiding contact with live parts and preventing safety problems such as short circuits. Moreover, the assembly and disassembly process of the fixing component is more convenient, requiring no complicated tools and operations, while ensuring the integrity of the disassembled component, facilitating subsequent maintenance and reuse.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To address the issue of low safety caused by the easy loosening of the battery pack fixing structure in the prior art, this invention provides a fixing component, a battery pack structure, and an energy storage box.

[0031] Please refer to Figures 1 to 7 As shown, in one aspect of the technical solution of the present invention, a fixing component is provided, including a mounting frame 1 and two fastening components 20; the mounting frame 1 includes two guide rail seats 10 disposed opposite to each other, forming a bearing space 11 between the two guide rail seats 10 for accommodating the component to be fixed, and a stop plate 12 is provided at one end of the guide rail seat 10 along its length direction; the two fastening components 20 are respectively disposed on the two guide rail seats 10 at the ends opposite to the stop plate 12, and the fastening component 20 includes a mounting member 21 and a first limiting member 22 and a second limiting member 23 respectively connected to the mounting member 21, the mounting member 21 being connected to the guide rail seat 10 and the component to be fixed to fix the component to be fixed; the first limiting member 22 and the second limiting member 23 are respectively engaged with the guide rail seat 10 to limit the movement of the mounting member 21 along the first direction and the second direction respectively.

[0032] In one aspect of the technical solution of this embodiment, after the mounting member 21 is connected to the guide rail seat 10 and the component to be fixed to secure it, the first limiting member 22 and the second limiting member 23 respectively limit the movement of the mounting member 21 along the first and second directions. This significantly reduces the shaking and displacement of the component to be fixed within the bearing space 11 and the loosening of the mounting member 21 during transportation. Compared with traditional fasteners, the fixing component in this application, by utilizing the cooperation of the first limiting member 22 and the second limiting member 23 with the guide rail seat 10, can maintain a tight state even under long-term vibration or temperature change environments, preventing the mounting member 21 from loosening and falling off, ensuring the safe fixing of the battery pack 30 and other components, thereby solving the problem of low safety caused by the easy loosening of the fixing structure of the battery pack 30 in the prior art. Furthermore, by cooperating with the guide rail seat 10, even if the mounting member 21 is loose, the component to be fixed can still be fixed, avoiding contact with live parts and preventing safety problems such as short circuits. Furthermore, the assembly and disassembly of the fixed components are more convenient, requiring no complicated tools or operations, while ensuring the integrity of the disassembled parts, facilitating subsequent maintenance and reuse.

[0033] In this embodiment, the first direction and the second direction are set perpendicular to each other.

[0034] like Figures 2 to 4As shown, the mounting component 21 includes a first mounting plate 210, a second mounting plate 211, and a third mounting plate 212. The first mounting plate 210, the second mounting plate 211, and the third mounting plate 212 are arranged perpendicularly to each other in pairs. Two adjacent mounting plates in the mounting component 21 are respectively connected to the guide rail seat 10 and the component to be fixed. The first limiting member 22 and the second limiting member 23 are respectively connected to another mounting plate in the mounting component 21. In this way, the three mounting plates of the mounting component 21 are perpendicularly connected to each other, forming a more stable structure, improving the mechanical strength and rigidity of the entire fastening assembly, and reducing the risk of deformation under external forces. Furthermore, the first limiting member 22 and the second limiting member 23 are respectively connected to the first mounting plate 210, allowing them to limit the movement of the mounting component 21 in different directions, thereby restricting the movement of the mounting component 21 in the first and second directions respectively, providing comprehensive stability control to prevent the mounting component 21 from loosening or falling off during transportation after being fixedly connected to the battery.

[0035] Specifically, the first mounting plate 210 has a first side portion 210a, and the first limiting member 22 includes a first bending plate 220 and a first limiting plate 221; the first bending plate 220 is connected to the first side portion 210a; the first limiting plate 221 is connected to the first bending plate 220, and the first limiting plate 221, the first bending plate 220, and the outer wall surface of the first mounting plate 210 form a first limiting groove 222, which is engaged with the bottom plate 13 of the guide rail seat 10 to limit the movement of the mounting member 21 along the first direction. In this way, by limiting the movement of the mounting member 21 along the first direction, it can be ensured that the mounting member 21 will not be displaced in this direction. Even if the battery encounters vibration or impact during transportation, the stability of the battery pack 30 and other fixed components can be maintained, reducing the risk of the mounting member 21 becoming loose. Furthermore, the first limiting groove 222 formed by the first bending plate 220, the outer wall of the first mounting plate 210, and the first limiting plate 221 forms a "closed" limiting structure. This structure provides stronger support and limiting capacity in the first direction. Compared to the method of connecting solely with the mounting member 21, it can withstand greater external forces without deformation or damage, allowing the mounting member 21 to be securely fixed in addition to fixing the component to be fixed. Moreover, the assembly and disassembly process of the fixing components is simpler and requires no complicated tools.

[0036] In this embodiment, the first bending plate 220 is made of plastic material, and the first limiting plate 221 is provided with a first stop 223 at one end away from the first bending plate 220. The bottom surface of the bottom plate 13 of the guide rail seat 10 is provided with a first mounting protrusion 130 so that after the first limiting groove 222 is engaged with the bottom plate 13 of the guide rail seat 10, the first limiting plate 221 drives the first stop 223 to move to abut against the side of the first mounting protrusion 130 away from the first bending plate 220.

[0037] Thus, since the first bending plate 220 is made of plastic material, during installation, it can be slightly deformed by controlling the first limiting plate 221 to adapt to the shape of the guide rail seat 10 base plate 13, ensuring a tight engagement between the first limiting groove 222 and the guide rail seat 10 base plate 13. After the first limiting groove 222 engages with the guide rail seat 10 base plate 13, the first stop 223 moves to abut against the first mounting protrusion 130. Even if vibration or impact occurs during transportation or operation, the cooperation between the first stop 223 and the first mounting protrusion 130 can prevent the mounting part 21 from moving along the first direction, thus preventing further loosening and providing a self-locking function. Furthermore, the plastic material of the first bending plate 220 is easy to adjust during assembly to ensure precise alignment of the first limiting groove 222 and the guide rail seat 10 base plate 13, thereby improving the overall assembly accuracy and efficiency. The cooperation between the first stop 223 and the first mounting protrusion 130 not only provides a limiting function in the initial stage of installation, but also maintains a stable connection between the first mounting plate 210 and the guide rail seat 10 during long-term use. Even in harsh environments (such as temperature changes, vibration, etc.), it can maintain a good fixing effect and prevent the mounting part 21 from loosening and the battery pack 30 from shifting.

[0038] Optionally, the first bending plate 220 and the first limiting plate 221 are both made of steel. The first limiting groove 222 formed by the bottom surfaces of the first bending plate 220, the first limiting plate 221 and the first mounting plate 210 is engaged with the bottom plate 13 of the guide rail seat 10 to limit the movement of the mounting part 21 in the first direction.

[0039] Optionally, the first bending plate 220 can be an arc-shaped plate or a right-angled plate, which can be adapted accordingly to the end face of the guide rail seat 10 along its length direction.

[0040] Specifically, the first mounting plate 210 also has a second side 210b that is connected to the first side 210a. The second limiting member 23 includes a second bent plate 230 and a second limiting plate 231. The second bent plate 230 is connected to the second side 210b. The second limiting plate 231 is connected to the second bent plate 230. The second limiting plate 231, the second bent plate 230, and the outer wall surface of the first mounting plate 210 form a second limiting groove 232. The second limiting groove 232 is engaged with the bottom plate 13 of the guide rail seat 10 to limit the movement of the mounting member 21 in the second direction. In this way, the second limiting groove 232 formed by the second bent plate 230, the second limiting plate 231, and the bottom surface of the first mounting plate 210 is engaged with the bottom plate 13 of the guide rail seat 10, which can effectively limit the movement of the mounting member 21 in the second direction. This means that the battery pack 30 fixing structure has limits not only in the first direction (i.e., the length direction of the guide rail 10) but also in the second direction (i.e., the width direction of the guide rail 10), providing comprehensive stability and anti-loosening protection. This multi-directional limiting design is not only crucial for preventing displacement of the battery pack 30 under various possible external forces but also plays a vital role in limiting and fixing the mounting component 21, especially during transportation or when subjected to vibration. Furthermore, the cooperation between the second limiting groove 232 and the base plate 13 of the guide rail 10 enables quick installation and disassembly without the need for complex tools or additional component structures, simplifying the assembly process, facilitating maintenance or replacement when needed, and improving operational efficiency.

[0041] In this application, the combined action of the second limiting member 23 and the first limiting member 22 significantly enhances the overall structural integrity of the entire fixing assembly. The first limiting member 22 and the second limiting member 23 operate in directions perpendicular to each other, forming a three-dimensional limiting network, which reduces the degree of freedom of movement of the battery pack 30 in various directions, thereby improving the rigidity and strength of the overall structure.

[0042] In this embodiment, the second bending plate 230 is made of plastic material, and the second limiting plate 231 is provided with a second stop 233 at one end away from the second bending plate 230. The bottom surface of the bottom plate 13 of the guide rail seat 10 is provided with a second mounting protrusion 131 so that after the second limiting groove 232 is engaged with the bottom plate 13 of the guide rail seat 10, the second limiting plate 231 drives the second stop 233 to move to abut against the side of the second mounting protrusion 131 away from the second bending plate 230.

[0043] In this way, the second bending plate 230, made of plastic material, can deform appropriately during installation to ensure a tight fit between the second limiting groove 232 and the base plate 13 of the guide rail seat 10. Once the second limiting groove 232 engages with the base plate 13 of the guide rail seat 10, the second stop 233 will move to abut against the second mounting protrusion 131, forming a self-locking state. Even if vibration or temperature changes occur during transportation or operation, it can effectively prevent the mounting part 21 from loosening along the second direction, providing additional safety assurance. It also helps to achieve precise alignment between the second stop 233 and the second mounting protrusion 131 of the base plate 13 of the guide rail seat 10 during assembly, ensuring a firm engagement between the second limiting groove 232 and the base plate 13 of the guide rail seat 10. This precise fit reduces the failure of the fixing structure due to assembly errors, improving the reliability and stability of the fixing components. This makes the installation and disassembly of the second limiting member 23 simpler, requiring no complicated tools or procedures. Simply align the second limiting groove 232 with the second mounting protrusion 131, and the clamping or disassembly can be achieved through plastic deformation, greatly facilitating on-site installation and maintenance.

[0044] Optionally, the second bending plate 230 and the second limiting plate 231 are both made of steel. The second limiting groove 232 formed by the bottom surfaces of the second bending plate 230, the second limiting plate 231 and the first mounting plate 210 is engaged with the bottom plate 13 of the guide rail seat 10 to limit the movement of the mounting part 21 in the second direction.

[0045] Optionally, the second bending plate 230 can be an arc-shaped plate or a right-angled plate, which can be adapted to the end face of the guide rail seat 10 along its length direction.

[0046] like Figures 1 to 4 As shown, the side plate 14 of the guide rail base 10 is provided with multiple first mounting holes 140, and the second mounting plate 211 is provided with multiple first connecting holes 211a. The multiple first mounting holes 140 and multiple first connecting holes 211a are arranged one-to-one, so that first connecting components are respectively passed through the first connecting holes 211a and the first mounting holes 140 to fix the second mounting plate 211 relative to the guide rail base 10. In the above arrangement, the first connecting components are bolts and nuts. Thus, by having the first connecting components respectively pass through the corresponding first mounting holes 140 and the first connecting holes 211a, the connection stability between the second mounting plate 211 and the guide rail base 10 is significantly enhanced, ensuring a precise connection between the mounting component 21 and the guide rail base 10, thereby improving the overall installation accuracy of the fixing assembly. This precise alignment allows the battery pack 30 to be stably installed within the bearing space 11, avoiding shaking and displacement caused by installation deviations.

[0047] In an exemplary embodiment of this application, optionally, the first mounting hole 140 is a strip-shaped hole extending along the length direction of the guide rail seat 10. Depending on the size of the battery pack 30, the first connecting member can be adjusted to any position within the first mounting hole 140 so that the mounting member 21 can be adapted to the battery pack 30 of different sizes and be securely fixed to it.

[0048] like Figure 5 As shown, the housing of the component to be fixed has multiple second mounting holes 31, and the third mounting plate 212 has multiple second connecting holes 212a. The multiple second mounting holes 31 and the multiple second connecting holes 212a are arranged one-to-one, so that second connecting components are respectively inserted into the second connecting holes 212a and the second mounting holes 31, thereby fixing the third mounting plate 212 relative to the component to be fixed. In this configuration, the second connecting components are bolts and nuts. Thus, by pre-setting the second mounting holes 31 and the second connecting holes 212a on the battery pack 30 housing and the third mounting plate 212, the assembly process becomes simpler and more intuitive. No complex alignment is required; simply inserting the second connecting components into the corresponding holes completes the fixing. This not only improves assembly accuracy but also reduces assembly time and enhances overall efficiency. When maintenance or replacement of the component to be fixed is required, the fixation between the third mounting plate 212 and the battery pack 30 can be released simply by disassembling the second connecting components, without disassembling the entire fixing assembly. This greatly simplifies the maintenance process, reduces maintenance costs, and facilitates on-site operation.

[0049] Another aspect of the technical solution of this invention provides a battery pack 30 structure, including the aforementioned fixing component and battery plate; the battery pack 30 is installed within the bearing space 11 of the fixing component. Thus, through the combined use of the mounting member 21, the first limiting member 22, and the second limiting member 23 of the fixing component, the battery pack 30 is securely fixed within the bearing space 11, reducing displacement and shaking caused by external factors such as vibration and impact during transportation or operation. Furthermore, the first limiting member 22 and the second limiting member 23 not only serve a positioning function during installation but also effectively prevent the mounting member 21 from loosening during long-term use. Even under harsh environmental conditions, the battery pack 30 maintains a stable and fixed state, avoiding safety risks caused by fastener failure and enhancing the overall mechanical stability of the battery pack 30 structure.

[0050] In another aspect of the technical solution of this invention, an energy storage box is provided, comprising a cluster support and at least one of the aforementioned battery pack 30 structures. The cluster support includes at least one receiving space for accommodating the battery pack 30 structures, and each receiving space is provided with a first support and a second support arranged opposite to each other. Two guide rail seats 10 of each battery pack 30 structure are respectively fixed to the first support and the second support within the receiving space. Thus, the connection between the fixing components and the cluster support ensures a tight connection between the battery pack 30 and the guide rail seats 10, preventing loosening and displacement of the battery pack 30 inside the energy storage box, reducing the possibility of the battery pack 30 contacting other live parts, and lowering electrical safety risks such as short circuits. It also simplifies the installation and disassembly process inside the energy storage box, eliminating the need for complex tools or operations; the fixing and releasing of the battery pack 30 can be completed through the first and second connecting components. This not only improves installation efficiency but also facilitates later maintenance and troubleshooting. Furthermore, the cluster support design of the energy storage box can adapt to battery pack 30 structures of different specifications. By adjusting the distance between the first and second brackets, as well as the position of the mounting holes on the guide rail seat 10, battery packs 30 of various sizes and shapes can be flexibly installed and fixed, improving the versatility and flexibility of the energy storage box.

[0051] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0052] The fixing assembly includes a mounting bracket 1 and two fastening components 20. The mounting bracket 1 includes two guide rail seats 10 arranged opposite each other, forming a bearing space 11 between the two guide rail seats 10 for accommodating the component to be fixed. A stop plate 12 is provided at one end of the guide rail seat 10 along its length direction. The two fastening components 20 are respectively provided on the two guide rail seats 10 at the ends opposite to the stop plate 12. The fastening component 20 includes a mounting member 21 and a first limiting member 22 and a second limiting member 23 respectively connected to the mounting member 21. The mounting member 21 is connected to the guide rail seat 10 and the component to be fixed to fix the component. The first limiting member 22 and the second limiting member 23 are respectively connected to the guide rail seat 10 to limit the movement of the mounting member 21 along the first direction and the second direction. In this way, after the mounting component 21 is connected to the guide rail seat 10 and the component to be fixed to secure it, the first limiting component 22 and the second limiting component 23 respectively limit the movement of the mounting component 21 along the first and second directions. This significantly reduces the shaking and displacement of the component to be fixed within the bearing space 11 and the loosening of the mounting component 21 during transportation. Compared with traditional fasteners, the fixing component in this application, by utilizing the cooperation of the first limiting component 22 and the second limiting component 23 with the guide rail seat 10, can maintain a tight state even under long-term vibration or temperature change environments, preventing the mounting component 21 from loosening and falling off, ensuring the safe fixing of the battery pack 30 and other components, thereby solving the problem of low safety caused by the easy loosening of the fixing structure of the battery pack 30 in the prior art. Furthermore, by cooperating with the guide rail seat 10, even if the mounting component 21 is loose, the component to be fixed can still be fixed, avoiding contact with live parts and preventing safety problems such as short circuits. Furthermore, the assembly and disassembly of the fixed components are more convenient, requiring no complicated tools or operations, while ensuring the integrity of the disassembled parts, facilitating subsequent maintenance and reuse.

[0055] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
