[0002] Currently, with the large-scale application of lithium batteries, their operating conditions are becoming increasingly diverse. To improve the adaptability and reliability of batteries in various complex environments, the industry has conducted extensive research on cell performance under different assembly orientations and usage scenarios. However, existing testing studies mainly focus on the performance of cells in the upright position (i.e., terminals facing upwards). There is a lack of systematic experimental data and in-depth analysis on the operating characteristics of cells in non-traditional installation orientations, especially the performance evolution mechanism, thermal management effect, and safety performance in the inverted position (terminals facing downwards).

[0003] Due to the lack of specific testing research for the inverted position, and the absence of standardized testing fixtures suitable for inverted cell testing, research progress in this area is hampered by unstable testing conditions and poor repeatability. Therefore, there is an urgent need to design a testing fixture suitable for inverted cell placement to achieve comprehensive performance evaluation of cells under multiple orientations and conditions, thereby further exploring the potential performance of lithium batteries and improving their comprehensiveness and reliability in engineering applications.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the tooling equipped with the battery cell 70 provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the tooling provided in an embodiment of the present utility model.

[0030] This utility model provides a tooling comprising a connecting assembly 30 and at least two clamping assemblies 20, which are arranged opposite each other along a first direction 50 to form a working cavity 40. The working cavity 40 is used by the at least two clamping assemblies 20 to clamp a battery cell 70. Each clamping assembly 20 has an opening 21 located at the bottom of the working cavity 40 and communicating with it. The opening 21 faces the first direction 50 and allows the aluminum busbar 80 of the battery cell 70 to pass through the working cavity 40. The connecting assembly 30 connects to the oppositely arranged clamping assemblies 20.

[0031] In practical applications, this technical solution forms a working cavity 40 by setting two clamping components 20 arranged opposite each other along the first direction 50, and opening 21 at the bottom of the working cavity 40, allowing the battery cell 70 to be placed in the working cavity 40 in an inverted manner, and the aluminum busbar 80 to pass through the opening 21 to the working cavity 40, avoiding deformation or damage caused by the aluminum busbar 80 being located in the clamping area. The clamping components 20 are fixedly connected by connecting components 30 to ensure structural stability. This structure can adapt to the testing requirements of the battery cell 70 under inverted conditions, providing sufficient space for the lead-out and connection of the aluminum busbar 80 while ensuring the stable positioning and clamping of the battery cell 70, improving the adaptability and operability of inverted testing, and making up for the technical defects of the existing test fixtures in terms of insufficient adaptability to inverted battery cell 70, thereby effectively expanding the applicable scope of multi-position performance testing of battery cell 70.

[0032] In some feasible implementations, see [reference] Figure 2 The clamping assembly 20 includes a clamping member 22 and at least two legs 23. The at least two clamping members 22 are arranged opposite each other to form a working cavity 40. The at least two legs 23 and the clamping members 22 together form an opening 21. The legs 23 are used to support the clamping members 22.

[0033] In practical applications, the clamping assembly 20 is refined into a combination structure of clamping members 22 and supporting legs 23. Multiple clamping members 22 are arranged opposite each other to form a stable working cavity 40 for accurate positioning and clamping of the battery cell 70. Multiple supporting legs 23, together with the clamping members 22, form a bottom opening 21, allowing the aluminum busbar 80 to naturally protrude from the bottom of the fixture when the battery cell 70 is inverted, avoiding obstruction or compression by the clamping members 22. The supporting legs 23 structurally support the clamping members 22, ensuring that the clamping members 22 are spaced apart from the ground and reserving space for the formation of the opening 21. This structural design is simple and practical, significantly improving the ease of clamping the inverted battery cell 70 during testing and the operability of connecting the aluminum busbar 80 to external wiring, thus better meeting the actual needs of inverted battery cell testing.

[0034] Further, see Figure 5 The clamping assembly 20 includes a chassis 24, which is located at the end of the support leg 23 away from the clamping member 22.

[0035] In practical applications, this technical solution, by setting a chassis 24 at the end of the support leg 23 away from the clamping member 22, allows the entire clamping assembly 20 to be more stably placed on the test platform or ground, effectively improving the overall stability of the fixture during use. The chassis 24, as the structural support base of the support leg 23, not only prevents the clamping assembly 20 from tilting or shifting during the clamping of the battery cell 70, but also withstands the gravitational load of the battery cell 70 in its inverted state, preventing tipping or slippage during clamping, thus ensuring the safety and reliability of the testing process. Furthermore, the chassis 24 also provides a mounting base for subsequently added functional components (such as fixing mechanisms or buffer pads), further enhancing the functional expandability and adaptability of the fixture. Overall, this solution improves the load-bearing capacity and operational safety of the fixture structure and optimizes the support conditions for the inverted testing of the battery cell 70.

[0036] Further, see Figure 5 The support leg 23 includes a base 231 and a threaded portion 232. The chassis 24 has a threaded hole 241. The threaded portion 232 is located at the end of the base 231 away from the clamping member 22. The threaded portion 232 and the threaded hole 241 are threadedly engaged.

[0037] In practical applications, the support leg 23 is divided into a base 231 and a threaded portion 232 at its lower end. The threaded portion 232 engages with the threaded hole 241 on the chassis 24, creating a detachable connection between the support leg 23 and the chassis 24. This structure facilitates the assembly and disassembly of the clamping assembly 20, improving the convenience and flexibility of the tooling during production, transportation, and maintenance. Furthermore, the threaded connection allows for fine-tuning of the height and angle of the support leg 23 during installation, enabling horizontal calibration of the clamping assembly 20 and ensuring alignment accuracy between multiple clamping assemblies 20, further enhancing the stability and reliability of clamping the battery cell 70. Additionally, this structure allows for the replacement of support legs 23 of different specifications or lengths according to different testing requirements, improving the tooling's versatility and adaptability. Therefore, this solution enhances the assembly flexibility, adjustability, and adaptability to various application scenarios of the tooling structure.

[0038] In some feasible implementations, see [reference] Figure 3 and Figure 4 The connecting component 30 includes a guide rail 31 that extends along a first direction 50. Oppositely disposed clamping components 20 are connected through the guide rail 31, and at least one clamping component 20 is slidably disposed on the guide rail 31 along the first direction 50.

[0039] In practical applications, the following example illustrates the process: the tooling includes two clamping components 20, both of which are slidably fitted onto the guide rail 31. When clamping the battery cell 70, first, one clamping component 20 is slidably fitted onto the guide rail 31. Then, the battery cell 70 is placed on the guide rail 31, ensuring it is in contact with the clamping component 20, with the aluminum busbar 80 protruding from the opening 21. Next, the other clamping component 20 is slidably fitted onto the guide rail 31, so that the two clamping components 20 are positioned opposite each other and clamp the battery cell 70. Finally, the positions of the two clamping components 20 are fixed, thus completing the clamping of the battery cell 70.

[0040] By incorporating a guide rail 31 within the connecting assembly 30 and extending the guide rail 31 along a first direction 50 relative to the clamping assemblies 20, while simultaneously slidingly mounting at least one clamping assembly 20 onto the guide rail 31, the clamping assembly 20 achieves mobility in the first direction 50. This structural design allows the distance between the clamping assemblies 20 to be flexibly adjusted according to the dimensions of different battery cells 70, adapting to battery cells 70 of different widths or specifications, thus improving the versatility and adaptability of the tooling. Furthermore, the guiding effect of the guide rail 31 ensures accurate and stable movement of the clamping assembly 20 during adjustment, effectively preventing the clamping member 22 from tilting or shifting, and improving the positioning accuracy and clamping reliability of the battery cell 70 during clamping. This structure also facilitates the installation and removal of the battery cell 70, reduces adjustment difficulty, and improves the operational efficiency and practicality of the tooling. In summary, this solution, through the guide rail 31 structure, achieves adaptability to battery cells 70 of different sizes, as well as ease and stability in clamping operations.

[0041] Furthermore, referring to Figure 3 and Figure 4 The connecting component 30 includes a slider 32, which is slidably disposed on the clamping component 20 along the second direction 60. The slider 32 has a first channel 321 along the first direction 50. The guide rail 31 is slidably engaged with the first channel 321. The clamping component 20 is slidably disposed on the guide rail 31 via the slider 32.

[0042] In practical applications, before clamping the battery cell 70, the space width occupied by the aluminum busbar 80 in the first direction 50 is first determined based on the dimensions of the battery cell 70. Then, a clamping assembly 20 is installed on the guide rail 31 via a slider 32, and the position of the guide rail 31 in the second direction 60 is adjusted to ensure that there is no interference between the guide rail 31 and the aluminum busbar 80. If there are multiple guide rails 31, the distance between adjacent guide rails 31 must be greater than the width of the space occupied by the aluminum busbar 80, so as to leave a complete passage for the aluminum busbar 80 to pass through. Next, another clamping assembly 20 is installed on the guide rail 31 via a slider 32, and the two clamping assemblies 20 are positioned opposite each other to clamp the battery cell 70, while ensuring that the aluminum busbar 80 passes through the opening 21 at the bottom of the working cavity 40.

[0043] By setting the slider 32, an intermediate structure is inserted between the clamping component 20 and the guide rail 31, allowing the clamping component 20 to slide and adjust along the first direction 50 of the guide rail 31 via the slider 32, thereby enhancing the flexibility and adaptability of the clamping component 20 during assembly. Simultaneously, the slider 32 body is slidably mounted on the clamping component 20 body along the second direction 60, allowing operators to laterally adjust or timely separate the position of the clamping component 20 during installation or adjustment of the tooling structure, improving the adaptability and ease of maintenance of the tooling. Furthermore, the slider 32 has a first channel 321 that slides with the guide rail 31, stably guiding the guide rail 31 along a predetermined direction, ensuring the straightness and positioning accuracy of the clamping component 20 during sliding, avoiding problems such as shaking, tilting, or jamming during sliding, thereby improving the stability, alignment accuracy, and clamping reliability of the overall clamping structure.

[0044] In summary, by setting up a slider 32 structure that slides in conjunction with the guide rail 31, the clamping assembly 20 can be independently adjusted in multiple directions, improving the spatial coordination, installation efficiency, and structural reliability during the clamping process of the battery cell 70. This effectively solves problems such as the avoidance of the aluminum busbar 80, the positioning accuracy of the battery cell 70, and the compatibility with multiple specifications, significantly enhancing the versatility and practicality of the tooling.

[0045] Optionally, refer to Figure 3 and Figure 4 The clamping assembly 20 has a second channel 25 along the second direction 60, the slider 32 is slidably engaged with the second channel 25, and the guide rail 31 is slidably disposed on the clamping assembly 20 along the second direction 60 via the slider 32.

[0046] In practical applications, by opening a second channel 25 on the clamping assembly 20 and sliding the slider 32 in the second channel 25, the position of the slider 32 can be flexibly adjusted in the second direction 60. At the same time, since the guide rail 31 is connected to the clamping assembly 20 through the slider 32, this structure also allows the guide rail 31 to slide along the second direction 60 on the clamping assembly 20 with the slider 32.

[0047] On the one hand, the second channel 25 provided in the clamping assembly 20 serves as the mounting channel for the slider 32, which not only provides a guiding structure for the slider 32 along the second direction 60, but also simplifies the assembly relationship between the slider 32 and the clamping assembly 20, and improves the modularity and assembly convenience of the structure. On the other hand, the sliding capability of the slider 32 in the second direction 60 allows the position of the guide rail 31 relative to the clamping assembly 20 to be finely adjusted, thereby facilitating the flexible change of the position of the guide rail 31 according to the requirements of different specifications of the battery cell 70 (especially the position of the aluminum busbar 80), and avoiding the guide rail 31 from interfering with the arrangement path of the aluminum busbar 80 of the battery cell 70.

[0048] Furthermore, referring to Figure 3 and Figure 4 The slider 32 has a first locking hole 323, which is connected to the second channel 25. The connecting component 30 includes a second locking member 34, which passes through the first locking hole 323 and is connected to the clamping component 20.

[0049] In practical applications, the second locking member 34 passes through the slider 32 through the first locking hole 323 and is connected to the clamping assembly 20, thereby locking the slider 32 and the clamping assembly 20, preventing the slider 32 from sliding or loosening unexpectedly along the second direction 60 during use, ensuring that the relative position of the clamping assembly 20 and the slider 32 is fixed, and improving the stability of the overall clamping structure.

[0050] Optionally, refer to Figure 3 and Figure 4 The slider 32 has a third channel 322 along the second direction 60. The clamping assembly 20 is slidably engaged with the third channel 322. The slider 32 is slidably disposed on the clamping assembly 20 through the third channel 322. The guide rail 31 is slidably disposed on the clamping assembly 20 along the second direction 60 through the slider 32.

[0051] In practical applications, by opening a third channel 322 on the slider 32 and sliding the clamping component 20 in the third channel 322, the slider 32 slides relative to the clamping component 20 along the second direction 60 through the third channel 322, thereby the guide rail 31 is slidably set on the clamping component 20 along the second direction 60 through the slider 32.

[0052] On the one hand, the slider 32 and the clamping assembly 20 achieve bidirectional sliding cooperation through the third channel 322, so that the slider 32 can not only slide relative to the guide rail 31, but also adjust its position relative to the clamping assembly 20 in the second direction 60, increasing the degree of freedom and adjustment flexibility of the structure. On the other hand, this design achieves fine adjustment of the position between the clamping assembly 20 and the guide rail 31 through the interlocking multi-layer sliding mechanism, meeting the diverse needs of different cell sizes 70 and aluminum busbar 80 arrangements. When the slider 32 slides along the second direction 60, it can drive the corresponding guide rail 31 to move along the second direction 60, thereby adjusting the position of the guide rail 31 and the spacing between adjacent guide rails 31.

[0053] Furthermore, the slider 32 has a second locking hole 323, which is connected to the third channel 322. The connecting assembly 30 includes a third locking member, which passes through the second locking hole 323 and is connected to the clamping assembly 20.

[0054] In practical applications, a second locking hole 323 is provided in the slider 32. The locking hole 323 is connected to the third channel 322 of the clamping component 20, and a third locking member is passed through the second locking hole 323 and connected to the clamping component 20 to realize the locking connection between the slider 32 and the clamping component 20.

[0055] Optionally, refer to Figure 3 and Figure 4 The guide rail 31 has a locking channel 311, which is connected to the first channel 321. The locking channel 311 extends along the first direction 50. The connecting component 30 includes a first locking member 33, which passes through the locking channel 311 and is connected to the clamping component 20.

[0056] In practical applications, a guide rail 31 is provided in the connecting assembly 30, and a locking channel 311 is formed on the guide rail 31. The locking channel 311 passes through the guide rail 31 and extends along the first direction 50. A first locking member 33 passes through the locking channel 311 and is connected to the clamping assembly 20, thereby realizing the locking connection between the clamping assembly 20 and the guide rail 31. In this application, the first locking member 33 is a bolt, which passes through the locking channel 311 and is threadedly connected to the clamping assembly 20.

[0057] This design allows the position of the clamping component 20 on the guide rail 31 to be locked, preventing the clamping component 20 from sliding or shifting unexpectedly during clamping or operation. This ensures the stability and positioning accuracy of the clamping component 20, and ensures that the battery cell 70 will not be loosened or displaced due to the loosening of the clamping component 20 during clamping, thereby improving the reliability of clamping and repeatability of positioning.

[0058] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0059] It should also be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or may be connected to an intermediary component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component through an intermediary component.

[0060] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
