[0045] Example 1

[0046] This embodiment provides a fixing device for testing the strength of battery terminals, which can achieve precise clamping in multiple directions, quick switching of test directions, and has higher ease of operation and adaptability.

[0047] It should be noted that the first direction in this embodiment is Figure 2 The X direction in the middle, the second direction is Figure 2 In the Y direction, the third direction is Figure 2 In the Z-direction, the first direction, the second direction, and the third direction are all mutually perpendicular. Specifically, one of the first direction, the second direction, and the third direction is the length direction of battery 1, one is the height direction of battery 1, and the third direction is the width direction of battery 1. In this embodiment, the first direction is the length direction of battery 1, the second direction is the width direction of battery 1, and the third direction is the height direction of battery 1. Furthermore, in this embodiment, the battery 1 has an electrode post disposed on its end face along the third direction.

[0048] Please refer to Figures 1 to 4 Specifically, the battery terminal strength testing fixing device is used in conjunction with the battery terminal strength testing device, which includes a first clamp and a second clamp arranged opposite each other in the same direction. The battery terminal strength testing fixing device includes a support plate 10, a tensile testing pressing assembly 20, and a pressure testing pressing assembly 30. The support plate 10 is fixedly connected to the first clamp; the tensile testing pressing assembly 20 is positionally adjustable and connected to the support plate 10, and is used to press the battery 1 onto the support plate 10 in a first or second direction to cooperate with the battery terminal strength testing device in performing a tensile test on the terminals of the battery 1; the battery 1 has terminals on its end face along a third direction; the pressure testing pressing assembly 30 is fixedly connected to the second clamp, and is used to press the battery 1 onto the support plate 10 in a third direction to cooperate with the battery terminal strength testing device in performing a pressure test on the terminals of the battery 1 in a third direction.

[0049] In this embodiment, the fixing device for testing the battery terminal strength involves a support plate 10 connected to the first clamp of the battery terminal strength testing device. The battery 1 is then pressed and fixed along a first and second direction using a tensile testing pressing assembly 20, according to the testing requirements. This ensures that the battery 1's terminals align with the testing direction of the battery terminal strength testing device along the first and second directions. A tensile force is applied to the terminals using the second clamp of the battery terminal strength testing device, thus achieving tensile testing of the battery 1's terminals along the first and second directions. Furthermore, a pressure testing pressing assembly 30 is connected to the second clamp of the battery terminal strength testing device. By adjusting the position between the first and second clamps, the pressure testing pressing assembly 30 presses against the battery 1's terminals along a third direction, applying pressure to the battery 1's terminals along that direction, thereby achieving pressure testing of the battery 1's terminals along that direction. This configuration makes the operation of testing the battery 1's terminals for strength more convenient. Furthermore, the position between the tensile testing pressing assembly 20 and the support plate 10 is adjustable, and the position between the first clamp and the second clamp on the battery terminal strength testing device is adjustable, making the position between the pressure testing pressing assembly 30 and the support plate 10 adjustable. This not only enables pressing of the battery 1 in various directions, but also allows the battery terminal strength testing fixing device to be adapted to various specifications of batteries 1 for strength testing, thus improving its adaptability.

[0050] It should be noted that when the terminal of battery 1 is subjected to tensile testing, a pull tab 2 is welded onto the terminal. The pull tab 2 is fixed to the second clamp of the battery terminal strength testing device so that the pull tab 2 is applied by the battery terminal strength testing device to apply tensile force to the terminal, thereby realizing the tensile test of the terminal.

[0051] Optionally, the pull tab 2 includes aluminum and copper sheets, which are adapted to use with poles of different polarities.

[0052] Furthermore, the aforementioned battery terminal strength testing device is a strength testing device used to detect the tensile and compressive forces of the terminals of battery 1, that is, a testing device for detecting the tensile strength and compressive strength of the terminals of battery 1, which is not specifically limited here. For example, the battery terminal strength testing device in this embodiment is a universal testing machine, which has advantages such as high precision, energy efficiency, and high performance.

[0053] Of course, in other embodiments, the tensile testing pressing assembly 20 described above can also press the battery 1 along a third direction and cooperate with the battery terminal strength testing device to perform a tensile test on the battery 1 in the third direction. This is not specifically limited here. This configuration in this embodiment is because in the conventional testing of terminals, only the pressure test of the terminal installation direction is required, while tensile tests are performed in the other two directions. Therefore, it only restricts the pressing of the battery 1 by the tensile testing pressing assembly 20 in the first and second directions. Of course, in other embodiments, the terminal installation direction can also be other directions, and the pressing direction of the tensile testing pressing assembly 20 on the battery 1 and the pressing direction of the pressure testing pressing assembly 30 on the battery 1 can be adapted accordingly. This is not specifically limited here.

[0054] Optionally, multiple tensile test pressing components 20 and pressure test pressing components 30 can be provided to improve the pressing and fixing effect on the battery 1, making it more firmly fixed on the support plate 10, thereby improving the test accuracy during the pole tensile test.

[0055] Please refer to Figure 1 , Figure 2 , Figure 3 , Figures 5 to 7 In this embodiment, the tensile testing pressing assembly 20 includes a pressing plate 21 and a connector 22. The pressing plate 21 is used to press the battery 1, and the connector 22 passes through the pressing plate 21 and can be detachably connected to the support plate 10 to press the battery 1 onto the support plate 10 along a first direction or a second direction. When pressing the battery 1 along the first direction, the battery 1 is first placed on the support plate 10 along the first direction, then the pressing plate 21 is placed on the battery 1, and then the connector 22 is passed through the pressing plate 21 and connected and fixed to the support plate 10, thereby achieving the pressing of the battery 1. When pressing the battery 1 along the second direction, the battery 1 is first placed on the support plate 10 along the second direction, then the pressing plate 21 is placed on the battery 1, and then the connector 22 is passed through the pressing plate 21 and connected and fixed to the support plate 10, thereby achieving the pressing of the battery 1. The above settings enable the tensile testing press assembly 20 to press the battery 1 in both the first and second directions, and also enable the pressing of batteries 1 of different specifications.

[0056] Optionally, multiple connectors 22 are provided to achieve more stable clamping of the clamping plate 21, thereby achieving a secure fixation of the battery 1.

[0057] Optionally, the detachable connection between the connector 22 and the support plate 10 can be a common detachable connection method such as a threaded connection or a snap-fit ​​connection. For example, in this embodiment, the two are threadedly connected, which not only enables the detachable connection between the two, but also allows adjustment of the relative position between the pressure plate 21 and the support plate 10.

[0058] Specifically, the connector 22 is provided with a first external thread, and the support plate 10 is provided with a first threaded hole 101. The first external thread and the first threaded hole 101 are threadedly connected, which not only allows adjustment of the relative position between the two, but also enables a detachable connection between them, facilitating disassembly and assembly. In use, the first external thread of the connector 22 passes through the pressure plate 21 and is pre-tightened with the first threaded hole 101 of the support plate 10. Then, by turning the connector 22 with a wrench, the connector 22 can be tightened, thereby pressing the battery 1.

[0059] In an optional embodiment, the connector 22 includes a fastening bolt 221, the outer periphery of which is provided with a first external thread. The fastening bolt 221 passes through the pressure plate 21 and can be threadedly connected to the first threaded hole 101 of the support plate 10; thus, the connector 22 and the support plate 10 can be threadedly connected.

[0060] In another optional embodiment, the connector 22 includes a fastening screw 222 and a fastening nut 223. One end of the fastening screw 222 passes through the pressure plate 21 and is threadedly connected to the first threaded hole 101 of the support plate 10, and the other end is threadedly connected to the fastening nut 223; the connector 22 can also be threadedly connected to the support plate 10.

[0061] To facilitate the operation of the workers, in this embodiment, the tensile test pressing assembly 20 is provided with two specifications: one for pressing and fixing the battery 1 along the first direction, and the other for pressing and fixing the battery 1 along the second direction.

[0062] Specifically, the clamping plate 21 includes a first clamping plate 211 and a second clamping plate 212. The first clamping plate 211 and the second clamping plate 212 are used to fix the battery 1 along the second direction and the first direction, respectively, so as to realize the tensile test of the battery 1 along the second direction and the first direction.

[0063] More specifically, the first pressure plate 211 is used in conjunction with the fastening bolt 221. Since the second direction of the battery 1, that is, the width direction of the battery 1, is smaller, a standard fastening bolt 221 can be used, which is low in cost and secure.

[0064] Optionally, the first pressure plate 211 is provided with a first through hole 2111, and the fastening bolt 221 passes through the first through hole 2111 to realize the passage and limiting of the fastening bolt 221.

[0065] More specifically, the second pressure plate 212 is used in conjunction with the fastening screw 222 and the fastening nut 223. Since the first direction of the battery 1, that is, the length direction of the battery 1, is relatively large, the two ends of the fastening screw 222 are selected for fixing. The distance between the second pressure plate 212 and the support plate 10 can be effectively adjusted through the two ends. It is also a standard part, with low cost and reliable fixing.

[0066] Optionally, the second pressure plate 212 is provided with a second through hole 2121, and the fastening screw 222 passes through the second through hole 2121 to realize the passage and limiting of the fastening screw 222.

[0067] Optionally, the fastening screw 222 is provided with a wrench groove 2221 in the middle to be compatible with an external wrench, making it easier for operators to perform the operation.

[0068] Please refer to Figure 1 , Figure 4 , Figure 8 and Figure 9 In this embodiment, the pressure testing and pressing assembly 30 includes a pressing head 31 and a mounting part 32. The pressing head 31 and the mounting part 32 are connected. The pressing head 31 can press against the terminal post of the battery 1 in a third direction. The mounting part 32 is used to connect with the second clamp. Thus, the pressing head 31 can be moved by the movement of the second clamp of the battery terminal post strength testing device, so as to press the battery 1 in a third direction.

[0069] Specifically, a first positioning hole 322 is provided through the outer periphery of the mounting part 32. The first positioning hole 322 is used for limiting connection with the second clamp of the battery terminal strength testing device. More specifically, the second clamp has a mounting hole, and the first positioning hole 322 is connected to the mounting hole. By limiting the connection through a positioning pin or other structure, the connection between the mounting part 32 and the second clamp can be realized.

[0070] More specifically, the pressure testing assembly 30 also includes a first locking nut 33, which is sleeved on the outer periphery of the mounting portion 32 and threadedly connected to the mounting portion 32. In use, the mounting portion 32 is inserted into the fixing hole of the second clamp, aligned with the first positioning hole 322 and the mounting hole, and then the first locking nut 33 is tightened so that it is threadedly connected to the mounting portion 32, so that the first locking nut 33 abuts against the second clamp, thereby achieving locking and fixing of the two.

[0071] Optionally, the mounting part 32 is provided with a third external thread 321 near the outer periphery of the pressure head 31, and the third external thread 321 is used for threaded connection with the first locking nut 33.

[0072] Optionally, the mounting part 32 is also provided with a blind hole 323 to reduce the weight of the mounting part 32.

[0073] Please refer to Figure 1 , Figure 10 and Figure 11 Furthermore, the fixing device for testing the strength of the battery terminal also includes a connecting component 40, which is connected to the support plate 10 and is used to fix the support plate 10 to the first clamp.

[0074] Specifically, the connecting component 40 includes a base 41 and a connecting part 42. The base 41 and the connecting part 42 are connected. The base 41 is fixedly connected to the support plate 10, and the connecting part 42 is used to connect with the first clamp, so that the support plate 10 can be fixed on the first clamp.

[0075] Specifically, a second positioning hole 422 is provided through the outer periphery of the connecting part 42. The second positioning hole 422 is used for limiting connection with the first clamp of the battery terminal strength testing device. More specifically, the first clamp has a connecting hole, and the second positioning hole 422 is connected to the connecting hole. By limiting the connection through a positioning pin or other structure, the connection between the connecting part 42 and the first clamp can be realized.

[0076] More specifically, the connecting assembly 40 also includes a second locking nut 43, which is sleeved on the outer periphery of the connecting part 42 and threadedly connected to the connecting part 42. In use, the connecting part 42 is inserted into the fixing hole of the first clamp, aligned with the second positioning hole 422 and the connecting hole, and limited in position; then the second locking nut 43 and the connecting part 42 are tightened, so that the second locking nut 43 abuts against the connecting hole, thereby achieving locking and fixing of the two.

[0077] Optionally, the connecting part 42 is provided with a fourth external thread 421 near the outer periphery of the base 41, and the fourth external thread 421 is used for threaded connection with the second locking nut 43.

[0078] Optionally, the connecting part 42 is also provided with a third through hole 423 to reduce the weight of the connecting part 42.

[0079] Specifically, the connecting assembly 40 also includes a fixing bolt 44. The support plate 10 is provided with a second threaded hole 102. The fixing bolt 44 passes through the base 41 and is threadedly connected to the second threaded hole 102, thereby realizing the fixation between the base 41 and the support plate 10.

[0080] Example 2

[0081] This embodiment provides a fixing device for testing the strength of battery terminals. The difference between this embodiment and Embodiment 1 lies in the setting specifications of the tensile testing pressing assembly 20 and the structure of the fastening screw 222.

[0082] Please refer to Figure 12 In this embodiment, the tensile testing press assembly 20 has only one structural specification. The fastening screw 222 includes a screw body 2222 and a threaded sleeve 2223. The screw body 2222 has a fifth external thread, and the threaded sleeve 2223 has a third threaded hole 22231 and a sixth external thread. A portion of the fifth external thread is threadedly connected to the third threaded hole 22231; another portion of the fifth external thread and any one of the sixth external threads are threadedly connected to the first threaded hole 101, and the other is threadedly connected to the fastening nut 223. This configuration not only allows for adjustment of the combined length of the screw body 2222 and the threaded sleeve 2223, but also allows one end of the fastening screw 222 to pass through the pressure plate 21 and be threadedly connected to the first threaded hole 101 on the support plate 10, while the other end is threadedly connected to the fastening nut 223, achieving the pressing and fixing effect of the pressure plate 21. This makes the tensile testing press assembly 20 more adaptable, and the fact that only one specification is provided simplifies the number of parts and makes operation more convenient.
