Description

Technical Field

[0001] This invention relates to the field of energy storage battery sampling technology, and in particular to a support structure for fixing aluminum busbars and a sampling bracket. Background Technology

[0002] In the CCS (Cell Contact System) injection-molded brackets of energy storage battery packs, the aluminum busbars are typically fixed using a hot-melt process, where the bracket plastic is melted at high temperatures to embed and solidify the aluminum busbars. This process has several drawbacks: First, it is complex, requiring specialized equipment and is time-consuming; second, it is prone to thermal damage, leading to bracket deformation or material degradation; third, it has low reliability, as the hot-melt points are prone to cracking under vibration or thermal cycling conditions, causing the aluminum busbars to loosen and abnormal contact resistance; furthermore, repair is difficult and costly, as the aluminum busbars are fused to the bracket as a single unit, and damage often necessitates the complete scrapping of the entire system. These problems not only threaten system safety but also significantly increase manufacturing costs. To meet the energy storage industry's demands for high safety, low cost, and efficient assembly, there is an urgent need for a hot-melt-free, quickly detachable, and highly reliable aluminum busbar fixing structure to completely replace the traditional hot-melt process.

[0022] Please also refer to Figures 1-4This invention provides a bracket structure for fixing aluminum busbars. This bracket structure aims to replace the traditional fixing method that relies on hot-melt processes. Through a purely mechanical snap-fit ​​structure, it achieves rapid, reliable, and detachable fixing of the aluminum busbars, thereby improving production efficiency, reducing manufacturing costs, and enhancing the stability of the structure under vibration or temperature change environments. The bracket structure 100 includes a bracket body 1, which has a receiving cavity 11 for accommodating the aluminum busbar 3. A limiting boss 4 is provided within the receiving cavity 11, which is used to pass through the positioning hole 31. An elastic snap 2 is provided on the side of the receiving cavity 11. The elastic snap 2 includes an elastic arm 21 and an abutment portion 22 provided on the elastic arm 21. A groove 23 is provided between the abutment portion 22 and the bottom surface of the receiving cavity 11. The groove 23 is used to accommodate the edge of the aluminum busbar 3, so that the abutment portion 22 abuts against the upper surface of the aluminum busbar 3.

[0023] In this embodiment, the support structure 100 includes a support body 1. The support body 1 can be made of insulating materials such as engineering plastics through injection molding to ensure its structural strength and electrical insulation performance.

[0024] On the upper surface of the bracket body 1, there are a plurality of receiving cavities 11 for accommodating aluminum busbars 3. The shape and size of the receiving cavity 11 match the aluminum busbars 3 to be fixed, providing a preset installation area for the installation of the aluminum busbars 3.

[0025] Inside the receiving cavity 11, specifically on the bottom surface of the receiving cavity 11, one or more limiting bosses 4 are provided. Correspondingly, the aluminum strip 3 to be fixed has positioning holes 31 corresponding to the position and shape of the limiting bosses 4. During assembly, the limiting bosses 4 can pass through the positioning holes 31 of the aluminum strip 3. This mating relationship plays a preliminary positioning role, which can effectively limit the translation of the aluminum strip 3 within the bottom surface of the receiving cavity 11, ensuring that the aluminum strip 3 is accurately placed in the predetermined position.

[0026] To reliably lock the aluminum busbar 3 within the receiving cavity 11 and prevent it from dislodging in the vertical direction, an elastic latch 2 is also provided on the side of the receiving cavity 11. In this embodiment, the elastic latch 2 specifically includes an elastic arm 21 and an abutment portion 22 disposed on the elastic arm 21.

[0027] One end of the elastic arm 21 is connected to the support body 1, and the other end is a free end, giving it a certain elastic deformation capability. The abutment part 22 is provided on the elastic arm 21, located on its free end. The abutment part 22 is suspended, and its bottom surface forms a slot 23 with a specific gap between it and the bottom surface of the receiving cavity 11. The height of the slot 23 matches the edge thickness of the aluminum strip 3, and is used to receive and clamp the edge part of the aluminum strip 3.

[0028] When the aluminum strip 3 is placed in the receiving cavity 11, and its positioning hole 31 is aligned with and fitted onto the limiting boss 4, the edge of the aluminum strip 3 is placed into the aforementioned slot 23. At this time, the abutting part 22 of the elastic buckle 2 will abut against the upper surface of the aluminum strip 3 from top to bottom by the rebound force of the elastic arm 21. In this way, the horizontal limiting of the limiting boss 4 at the bottom and the vertical limiting of the elastic buckle 2 on the side form a two-way locking of the aluminum strip 3, thereby achieving a stable and reliable fixation. The entire installation process does not require heating or the use of additional tools, and the operation is simple and quick. In addition, when maintenance or replacement is required, the aluminum strip 3 can be easily removed by prying the elastic arm 21 outward, achieving non-destructive disassembly.

[0029] In one embodiment, the abutment portion 22 is provided with a guide slope 221, which is inclined from top to bottom toward the receiving cavity 11 to guide the aluminum strip 3 to be pressed down into the receiving cavity 11.

[0030] In this embodiment, to facilitate the smooth entry of the aluminum busbar 3 into the receiving cavity 11 and its eventual insertion into the slot 23, a guide slope 221 is provided on the abutment portion 22. The guide slope 221 is located on the inner side of the abutment portion 22, and its surface shape is inclined from top to bottom towards the interior of the receiving cavity 11.

[0031] During assembly, after the positioning hole 31 of the aluminum strip 3 is initially aligned with the limiting boss 4, the operator presses the aluminum strip 3 downwards. At this time, the edge of the aluminum strip 3 will first contact the guide slope 221 on the abutment part 22.

[0032] As downward pressure continues to be applied, the guide ramp 221 decomposes the vertically downward pressing force into a horizontal component pointing outwards from the receiving cavity 11. This horizontal component acts on the abutment part 22 and the elastic arm 21 below it, forcing the abutment part 22 to expand outwards while the elastic arm 21 also undergoes elastic deformation outwards. When the aluminum strip 3 is pressed down further, its edge completely slides over the guide ramp 221, and the aluminum strip 3 is completely inserted into the receiving cavity 11, with its edge also completely locked into the slot 23. At this point, the pressure that previously forced the elastic arm 21 to deform outwards disappears, and the elastic arm 21 instantly rebounds to its initial position due to its own elastic restoring force. The abutment part 22 also abuts against the upper surface of the edge of the aluminum strip 3, achieving locking.

[0033] By setting this guide ramp 221, the installation operation is simplified, achieving a quick "press and snap" assembly effect. This effectively avoids potential damage to the aluminum strip 3 or the bracket structure 100 itself due to improper force during installation, improving assembly efficiency and reliability. In a specific example, the inclination angle of the guide ramp 221 (e.g., the angle with the vertical direction) can be set to 30°-45° to achieve a balance between providing good guiding effect and ensuring structural strength.

[0034] In one embodiment, the resilient buckles 2 are respectively provided on multiple sides of the receiving cavity 11, wherein the minimum distance between the guide slopes 221 of the resilient buckles 2 located on opposite sides is less than the size of the aluminum strip 3 in the corresponding direction.

[0035] In this embodiment, multiple elastic buckles 2 are respectively provided on the sides of the receiving cavity 11. Specifically, multiple elastic buckles 2 can be provided on the circumferential sides of the receiving cavity 11. For example, at least one or more elastic buckles 2 are provided on each of the four sides of the receiving cavity 11 on opposite sides to achieve multi-point support and locking of the aluminum strip 3. This arrangement makes the fixing force more evenly distributed and improves the vibration resistance of the overall structure.

[0036] Furthermore, to ensure that the elastic buckle 2 can generate sufficient elastic deformation and ultimately reliably spring back and lock during assembly, the minimum distance between the guide ramps 221 of the elastic buckles 2 on opposite sides of the receiving cavity 11 is designed to be less than the dimension of the aluminum strip 3 in the corresponding direction. This minimum distance specifically refers to the distance between the innermost points of the guide ramps 221 on opposite sides in the unstressed state.

[0037] During assembly, when the aluminum strip 3 is pressed downwards, its edge first contacts the guide ramp 221. Since this minimum distance is less than the corresponding size of the aluminum strip 3, the edge of the aluminum strip 3 forces the abutment portion 22 and its underlying elastic arm 21 to expand outwards, resulting in elastic deformation. As the aluminum strip 3 continues to be pressed down and fully enters the receiving cavity 11, its edge engages with the slot 23, the elastic arm 21 rebounds, and the abutment portion 22 returns to its initial position, thus firmly clamping the aluminum strip 3 between the elastic latches 2 on opposite sides. This dimensional relationship ensures sufficient interference, providing reliable locking force to prevent the aluminum strip 3 from loosening in a vibrating environment. This design also provides feedback (such as a "click") after assembly. The "click" sound is the sound produced when the elastic latch 2 completes its elastic deformation and instantly rebounds to its original position, causing its abutment portion 22 to rapidly impact the surface of the aluminum strip 3.

[0038] In one embodiment, the bracket body 1 and the limiting boss 4 are integrally injection molded.

[0039] In this embodiment, the bracket body 1 and the limiting boss 4 are integrally formed by injection molding. Specifically, during the manufacturing process, engineering plastic is used as the raw material, and the bracket body 1 and the limiting boss 4 are formed in one piece using an injection mold. This integral molding process ensures that there are no seams or connecting interfaces between the limiting boss 4 and the bracket body 1, thereby avoiding the strength weaknesses or assembly errors that may be caused by traditional assembly methods.

[0040] With its one-piece molding design, the limiting boss 4 protrudes directly upwards from the bottom surface of the receiving cavity 11, forming a continuous structure with the bracket body 1. This design not only improves the shear and impact resistance of the limiting boss 4 but also simplifies the production process, eliminating the need for additional welding or bonding steps, thereby reducing manufacturing costs and defect rates. During assembly, the positioning holes 31 of the aluminum strip 3 are directly fitted onto the one-piece molding limiting boss 4, and combined with the locking action of the elastic buckle 2, reliably fixing the aluminum strip 3 is achieved. The entire structure maintains higher stability under vibration or temperature change environments, avoiding material deterioration or cracking problems that may be caused by hot-melt processes.

[0041] In one embodiment, the limiting boss 4 includes a limiting part 42 connected to the bracket body 1 and a guide part 41 disposed at the top of the limiting part 42. The cross-sectional dimension of the top surface of the guide part 41 is smaller than the cross-sectional dimension of the top surface of the limiting part 42, and the outer peripheral wall of the guide part 41 extends obliquely from the top surface of the guide part 41 toward the top surface of the limiting part 42.

[0042] In this embodiment, the limiting boss 4 specifically includes a limiting part 42 and a guide part 41. The limiting part 42 is located at the lower part of the limiting boss 4, and its bottom end is connected to the bottom surface of the receiving cavity 11 of the bracket body 1, which is used to provide the main limiting support after the aluminum strip 3 is installed. The guide part 41 is provided at the top of the limiting part 42, forming the upper structure of the limiting boss 4.

[0043] Furthermore, the cross-sectional dimension of the top surface of the guide portion 41 is smaller than the cross-sectional dimension of the top surface of the limiting portion 42. Specifically, the cross-section can be circular, with the top surface of the guide portion 41 being smaller and the bottom surface being larger, thus forming a frustum-shaped structure with a small top and a large bottom.

[0044] Furthermore, the outer peripheral wall of the guide portion 41 extends obliquely from the top surface of the guide portion 41 toward the top surface of the limiting portion 42, forming an outwardly widening conical structure. This oblique design causes the outer peripheral wall of the guide portion 41 to exhibit a gradually widening shape from top to bottom in the vertical direction.

[0045] During assembly, when the positioning hole 31 of the aluminum busbar 3 approaches the limiting boss 4, the smaller top surface and inclined outer peripheral wall of the guide part 41 guide the positioning hole 31 to quickly align and slide into the limiting part 42. Even if there is a slight deviation in the initial alignment, the inclined outer peripheral wall will gradually correct the positioning hole 31 of the aluminum busbar 3 to the correct position through sliding contact, eventually allowing the positioning hole 31 to be completely fitted onto the limiting part 42. This structure optimizes the pre-positioning process, reduces assembly errors, and improves operational efficiency and overall structural reliability.

[0046] In one embodiment, the top surface of the guide portion 41 is higher than the top surface of the abutment portion 22 in a direction perpendicular to the bottom surface of the receiving cavity 11.

[0047] In this embodiment, in the direction perpendicular to the bottom surface of the receiving cavity 11 (i.e., the height direction), the top surface of the guide portion 41 is set higher than the top surface of the abutment portion 22. Specifically, this height relationship makes the guide portion 41 of the limiting boss 4 in a relatively "high position" in the overall structure, while the abutment portion 22 of the elastic buckle 2 is in a relatively "low position", thereby forming a stepped locking structure.

[0048] During assembly, this height difference design allows the operator to first align the positioning hole 31 of the aluminum strip 3 and fit it onto the higher guide part 41, achieving pre-positioning. At this time, the edge of the aluminum strip 3 has not yet contacted the lower abutment part 22, avoiding interference from simultaneously handling multiple limiting structures. Subsequently, by continuing to press down on the aluminum strip 3, its edge will contact the guide slope 221 of the abutment part 22 and finally lock into the slot 23 through elastic deformation. This step-by-step assembly method (pre-positioning, then locking) clearly separates the horizontal alignment operation from the vertical locking operation, reducing assembly difficulty, increasing the first-time success rate of assembly, and avoiding the risk of component damage due to tilted or misaligned installation. At the same time, this design ensures that the aluminum strip 3 is not easily dislodged under vibration or impact environments, completely avoiding the defects of traditional hot-melt processes.

[0049] In one embodiment, the height difference between the top surface of the guide portion 41 and the top surface of the abutment portion 22 is 0.5-1mm.

[0050] In this embodiment, the height difference between the top surface of the guide portion 41 and the top surface of the abutment portion 22 is set to 0.5-1mm. The specific value of this height difference can be finely adjusted according to the thickness of the aluminum strip 3, the elastic modulus of the elastic buckle 2, and the overall structural dimensions, but it should be kept within the range of 0.5-1mm to ensure sufficient pre-positioning space without affecting the compactness of the overall structure.

[0051] In practical applications, this height difference allows the top surface of the guide part 41 to protrude upwards 0.5-1mm beyond the top surface of the abutment part 22 during the pre-positioning stage, thereby providing sufficient guiding margin for the aluminum busbar 3 and avoiding assembly resistance caused by premature contact with the abutment part 22.

[0052] In one embodiment, the elastic arm 21 is vertically fixed to the upper surface of the bracket body 1, the abutment portion 22 is fixedly connected to the top end of the elastic arm 21, and the gap between the bottom surface of the abutment portion 22 and the bottom surface of the receiving cavity 11 forms the slot 23.

[0053] In this embodiment, the elastic arm 21 of the elastic buckle 2 is fixedly connected to the upper surface of the bracket body 1 in a vertical direction. Specifically, the elastic arm 21 can be an integrally formed structure extending upward from the upper surface of the bracket body 1, with its root firmly connected to the bracket body 1, and its arm body perpendicular to the bottom surface of the receiving cavity 11, so that when subjected to a horizontal external force, it can undergo bending elastic deformation with its root as the fulcrum.

[0054] The abutment portion 22 is fixedly connected to the top end (i.e., the free end) of the elastic arm 21. The abutment portion 22 extends from the top end of the elastic arm 21 into the receiving cavity 11, forming a cantilever structure. Since the abutment portion 22 is suspended, a predetermined gap is naturally formed between its bottom surface and the bottom surface of the receiving cavity 11. The size of this gap matches the thickness of the aluminum strip 3 to be fixed, thus forming a slot 23 for receiving and clamping the edge of the aluminum strip 3.

[0055] During assembly, the positioning hole 31 of the aluminum strip 3 is first aligned with the limiting boss 4 and inserted to achieve pre-positioning. Then, the aluminum strip 3 is pressed down, its edge contacting the abutment part 22 and forcing the elastic arm 21 to elastically deform outwards. When the edge of the aluminum strip 3 slides into the slot 23, the elastic arm 21 rebounds, and the bottom surface of the abutment part 22 and the bottom surface of the receiving cavity 11 together clamp the edge of the aluminum strip 3, achieving vertical locking. This structural design clearly defines the deformation mode of the elastic arm 21 and the locking mechanism of the abutment part 22, making the function of the elastic buckle 2 more reliable and predictable. At the same time, this vertical elastic arm 21 design also allows for sufficient elastic travel within a limited space, meeting the needs of rapid assembly and disassembly.

[0056] In one embodiment, the support body 1 is provided with a plurality of surrounding plates 12, the plurality of surrounding plates 12 extending upward to form a plurality of receiving cavities 11 on the upper surface of the support body 1; the side of the surrounding plate 12 is provided with a notch 121, and the elastic buckle 2 is provided in the corresponding notch 121.

[0057] In this embodiment, the support body 1 is provided with multiple surrounding plates 12. These surrounding plates 12 can be integrally formed structures extending upward from the upper surface of the support body 1, made of the same material as the support body 1, and arranged at a preset spacing and in a predetermined pattern, thereby dividing and forming multiple independent receiving cavities 11 on the upper surface of the support body 1. Each receiving cavity 11 is used to accommodate one aluminum busbar 3, realizing a modular fixing design. This multi-cavity structure allows the support body 1 to support multiple aluminum busbars 3 simultaneously, making it suitable for applications such as energy storage PACK package CCS brackets that require the acquisition of multiple signals, thus improving the overall structural utilization efficiency.

[0058] Furthermore, the side of the enclosure 12 is provided with notches 121, the position and size of which match the elastic buckles 2. The elastic buckles 2 are disposed within the corresponding notches 121. Specifically, the elastic arm 21 of the elastic buckle 2 can extend upward from the upper surface of the support body 1 at the bottom of the notch 121, so that the abutment part 22 is located on the side of the receiving cavity 11. This arrangement allows the elastic buckles 2 to be embedded in the notches 121 of the enclosure 12 without occupying additional external space, ensuring the compactness of the structure, while facilitating the elastic deformation of the elastic arm 21 within the space provided by the notch 121 without interfering with other structures.

[0059] During assembly, the limiting boss 4 within each receiving cavity 11 passes through the positioning hole 31 of the aluminum strip 3 to achieve pre-positioning; subsequently, the edge of the aluminum strip 3 is guided and locked into the slot 23 by the elastic buckle 2. The design of the surrounding plate 12 not only provides boundary limiting for the receiving cavities 11, but also enhances the isolation between adjacent receiving cavities 11. This structure optimizes the overall stability of the bracket body 1 and allows for independent operation of individual receiving cavities 11 during maintenance without affecting other parts.

[0060] like Figure 3 and Figure 4 As shown, corresponding to the above-mentioned bracket structure for fixing aluminum busbars, this embodiment of the invention also provides a sampling bracket, including the bracket structure 100 described in the foregoing embodiment, wherein an aluminum busbar 3 is fixedly disposed in the receiving cavity 11 of the bracket structure 100.

[0061] In this embodiment, the sampling bracket has a bracket body 1 as its core, and an aluminum busbar 3 is fixedly installed in the receiving cavity 11 formed on its upper surface. The aluminum busbar 3, as part of the sampling assembly, is used to collect the voltage, temperature or other electrical signals of the battery module, and is mechanically fixed without heat melting through the limiting boss 4 and elastic buckle 2 of the bracket structure 100.

[0062] In actual assembly, the positioning holes 31 of the aluminum busbar 3 pass through the limiting boss 4, and its edges are engaged in the slots 23 of the elastic buckle 2, and held against the upper surface by the abutment part 22, thus being firmly fixed in the receiving cavity 11. This fixing method does not require a hot-melt process, avoiding thermal damage and material degradation, and ensuring the reliability of the sampling bracket under environments such as vibration and thermal cycling. At the same time, the sampling bracket can integrate multiple receiving cavities 11 to support the parallel fixing of multiple aluminum busbars 3, which is suitable for CCS (Cell Connection System) acquisition structures of square, pouch or cylindrical battery modules.

[0063] During battery module assembly, the aluminum busbar 3 is first positioned on the limiting boss 4, and then pressed down so that its edge is engaged with the slot 23 through the guide ramp 221, achieving quick locking. During disassembly, the aluminum busbar 3 can be removed without damage simply by prying open the elastic arm 21, facilitating maintenance and replacement. This design improves assembly efficiency, reduces costs, and provides assembly feedback (such as a "click"), completely solving the defects of traditional hot-melt processes. This sampling bracket can be directly integrated into energy storage battery packs or new energy vehicle power battery modules, serving as a support and connection component for CCS (Cell Contacting System) or FPC / FFC (Flexible Printed Circuit / Flexible Flat Cable) sampling systems, providing a stable and reliable signal acquisition foundation for the battery management system.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
