Description

Technical Field

[0001] This disclosure relates to the field of batteries, and in particular, to a device for simulating the swaying test of battery terminals under stress. Background Technology

[0002] Inside a battery, tabs connect the cell electrically and mechanically to the external terminals. However, under complex operating conditions, especially with mechanical vibration and impact, external loads act directly on the battery terminals and are further conducted to the tab connection. Since the tabs are typically made of thin sheet metal, they are prone to metal fatigue at stress concentration points under long-term, multi-directional alternating stress, leading to tearing at the connection between the tab and the terminal. This directly increases the battery's internal resistance, causes abnormal heating, and can even create serious safety hazards. Utility Model Content

[0003] In view of this, the present disclosure provides a device for simulating the force swing test of battery terminals, used to test the tearing state of the battery tabs. The device includes a platform, a support mechanism, a fixing mechanism, a swing mechanism, and a clamping mechanism. The platform includes a mounting plane. The support mechanism is disposed on the mounting plane and is used to support the battery. The fixing mechanism is disposed on the platform, and a portion of the fixing mechanism is movable relative to the support mechanism to press or release the battery. The swing mechanism is disposed on the platform and spaced apart on opposite sides of the support mechanism in a first direction. The clamping mechanisms are connected to the swing mechanisms and are used to clamp the battery terminals. The swing mechanism drives the clamping mechanism to swing, simulating the force swing of the battery terminals.

[0004] This disclosed simulated battery terminal force swing test device simulates the stress state of the terminal under vibration environment by applying controllable swing to the terminal, thereby transferring stress to the tab connection. During the fatigue accumulation process caused by continuous swing, the tab may break or tear. The bearing mechanism is used to support the battery and, together with the fixing mechanism, reliably fixes the battery, thereby effectively isolating the overall displacement or vibration of the battery body caused by the terminal swing. This ensures that the externally input swing load can be accurately transferred to the internal tab connection through the terminal, rather than being offset by the movement of the battery body, thus eliminating the interference of battery body shaking on the test results. The clamping mechanism can form a reliable electrical and mechanical connection with the terminal to transmit the swing. The swing mechanism can control the swing angle and frequency to reproduce the working condition of the terminal under long-term, multi-directional alternating stress, accelerating the induction of metal fatigue at the internal tab connection until it tears or breaks. This simulated battery terminal force swing test device simulates the stress borne by the terminal under complex working conditions to evaluate the health status of the internal tab connection, thereby reducing the economic losses caused by battery connection failure in actual production.

Detailed Implementation

[0015] Numerous specific details are set forth below to provide an understanding of the structure, function, and use of the embodiments described and illustrated in the specification and figures. It is to be understood that the embodiments described and illustrated herein are non-limiting examples, and thus it will be appreciated that the particular structural and functional details disclosed herein are representative and exemplary. Variations and changes may be made to these embodiments without departing from the scope of the claims.

[0016] This disclosure provides a device for simulating the swaying test of battery terminals under stress. (Reference) Figure 1 and Figure 2 This simulated battery terminal force swing test device 100 is used to test the state of the electrode tab tearing. The device includes a support mechanism 10, a fixing mechanism 20, a clamping mechanism 30, a swinging mechanism 40, and a platform 50. The platform 50 includes a mounting plane 51. The support mechanism 10 is disposed on the mounting plane 51 and is used to support the battery 200. The fixing mechanism 20 is disposed on the platform 50, and a portion of the fixing mechanism 20 is movable relative to the support mechanism 10 to press or release the battery 200. The swinging mechanism 40 is disposed on the platform 50 and spaced apart on opposite sides of the support mechanism 10 in a first direction. The clamping mechanism 30 is connected to the swinging mechanism 40 and is used to clamp the terminal 210 of the battery 200. The swinging mechanism 40 drives the clamping mechanism 30 to swing, simulating the force swing of the terminal 210 of the battery 200.

[0017] The simulated battery terminal stress swing test device 100 disclosed herein simulates the stress state of the terminal 210 under vibration environment by applying controllable swing to the terminal 210, thereby transferring stress to the tab connection. During the fatigue accumulation process caused by continuous swing, the tab may break or tear. This simulated battery terminal stress swing test device 100 can test both terminals 210 separately. In the actual battery 200 usage environment, both terminals 210 will simultaneously bear complex mechanical stress from the outside, accurately reproducing the stress state of the two terminals 210 in a real vibration environment, making the stress state of the internal tab highly consistent with the actual situation, thereby greatly improving the authenticity and reliability of the test results. The supporting mechanism 10 supports the battery 200 and, together with the fixing mechanism 20, reliably fixes the battery 200, thereby effectively isolating the overall displacement or vibration of the battery 200 body caused by the swing of the terminal post 210. This ensures that the externally input swing load can be accurately transmitted to the internal tab connection through the terminal post 210, rather than being offset by the movement of the battery 200 body, thus eliminating the interference of the battery 200 body's shaking on the test results. The clamping mechanism 30 can form a reliable electrical and mechanical connection with the terminal post 210 to transmit the swing. The swing mechanism 40 can control the swing angle and frequency to reproduce the working conditions of the terminal post 210 under long-term, multi-directional alternating stress, accelerating the induction of metal fatigue at the internal tab connection until it tears or breaks. This simulated battery terminal post force swing test device 100 simulates the stress borne by the terminal post 210 under complex working conditions to evaluate the health status of the internal tab connection, thereby reducing the economic losses caused by battery 200 connection failure in actual production. The battery 200 in this disclosure may refer to an OS battery (One-Stop battery). OS batteries are easy to assemble, reduce the overall height of the battery, such as the ground clearance of a car to reduce the risk of collisions, and also reduce the amount of precious metals such as nickel, cobalt, and lithium used, effectively saving costs.

[0018] refer to Figure 2 and Figure 3 The swing mechanism 40 includes a first swing link 41, a second swing link 42, a third swing link 43, and a clearance assembly 44. The clearance assembly 44 includes a mounting platform 441 and a drive member 442. The mounting platform 441 is mounted on the platform 50, and the swing mechanism 40 is mounted on the mounting platform 441. The drive member 442 drives the mounting platform 441 to move between a first position close to the support mechanism 10 and a second position away from the support mechanism 10. Figure 2 The diagram shows the avoidance component 44 in the first position, as shown. Figure 6The diagram shows the obstacle avoidance component in the second position. When the battery 200 is not being tested, the drive unit 442 drives the mounting platform 441, along with the entire swing mechanism 40, to move to the second position, i.e., the obstacle avoidance station, thus providing unobstructed and ample space for operators or automated robots to pick up and place the battery 200. This completely avoids the risk of collision injury to the operator caused by the clamping mechanism 30 or the swing mechanism 40, or accidental scratching of the battery 200 terminals 210 and casing, when operating in a confined space. When the battery 200 to be tested is moved into the carrying mechanism 10, ready for testing, the mounting platform 441 then returns to the first position, i.e., the testing station, for testing. This achieves precise and rapid positioning of the simulated battery terminal force swing test device 100 and the terminals 210 on the battery 200. The first swing link 41 has a first oblong hole 411, and one end of the second swing link 42 is slidably connected to the first oblong hole 411 and can move along the length direction of the first oblong hole 411. Figure 2 In the Y+Y- direction, the other end of the second swing link 42 is hinged to the third swing link 43 via a connecting pin 423, thereby driving the third swing link 43 to move in the mutually perpendicular first and second directions. One end of the second swing link 42 is connected to the first oblong hole 411 of the first swing link 41. This connection point can be adjusted and slid along the length of the hole, enabling stepless adjustment of the output amplitude of the entire swing mechanism 40. This provides flexibility for simulating vibration conditions of different intensities. The other end of the second swing link 42 is hinged to the third swing link 43 via the connecting pin 423. This decomposes the rotational motion of the second swing link 42 and transmits it to the third swing link 43, ultimately driving the third swing link 43 to generate a composite motion in the mutually perpendicular first and second directions, thereby driving the clamping mechanism 30 to move in multiple directions.

[0019] For ease of description, in the accompanying drawings of this disclosure, arrows X+ and X- respectively indicate opposite sides in a first direction, and arrows Y+ and Y- respectively indicate opposite sides in a second direction.

[0020] refer to Figure 2 and Figure 3The second swing link 42 includes a first rod portion 421 and a second rod portion 422. The first rod portion 421 is slidably connected to the first oblong hole 411 of the first swing link 41 via a first connector 424. By changing the position of the first connector 424 in the first oblong hole 411, the swing length of the second swing link 42 can be adjusted. The first rod portion 421 has a second oblong hole 4211, and the second rod portion 422 is slidably connected to the second oblong hole 4211 via a second connector 425. By changing the position of the second connector 425 in the second oblong hole 4211, the swing length of the second swing link 42 can be adjusted. By adjusting the positions of the first connector 424 and the second connector 425 in their respective oblong holes individually or in combination, the effective operating length of the second swing link 42 can be continuously changed. Since the second swing link 42 is the key input to drive the movement of the third swing link 43, the third swing link 43 can be precisely calibrated or the amplitude of the final swing trajectory of the clamping mechanism 30 can be changed as needed to match different test standards or simulate different actual swing states.

[0021] Figure 4 The image shows the fixing mechanism 20 raised, with no battery 200 placed on it. The fixing mechanism 20 may include a pressure plate 21, which is located on the side facing the supporting mechanism 10 and is used to press the battery 200. The pressure plate 21 can contact the upper surface of the battery 200 through its plane, which can evenly distribute the pressing force to the entire force-bearing surface of the battery 200. The supporting mechanism 10 has a limiting groove 11 on the side facing the pressure plate 21, which is used to accommodate and position the battery 200. The operator only needs to place the battery 200 into the limiting groove 11 to complete the preliminary positioning on the horizontal plane without precise measurement. This greatly simplifies the loading and unloading operation, shortens the preparation time for each test, and effectively improves the testing efficiency. At the same time, it also eliminates the spatial position change of the terminal post 210 caused by manual placement deviation, thereby ensuring that the load applied by the swing mechanism 40 to different batteries 200 is consistent, making the final test results highly reliable and comparable. The pressure plate 21 can prevent excessive local stress from damaging the battery 200, while ensuring that the battery 200 will not warp or shake during the test, providing a stable mechanical environment for the test. At the same time, it ensures that the battery 200 body is effectively constrained during simulated vibration, and that the externally input swing load can be almost entirely transmitted to the internal electrode tab connection through the terminal post 210, rather than being offset by the inertial movement of the battery 200 as a whole, thus realistically reproducing the force boundary conditions of the terminal post 210 in the battery pack.

[0022] refer to Figure 5The fixing mechanism 20 also includes a pressure plate cylinder 22 and a fixing platform 23. The cylinder body 221 of the pressure plate cylinder 22 is fixed to the fixing platform 23, and the piston rod 222 of the pressure plate cylinder 22 is connected to the pressure plate 21 to drive the pressure plate 21 to move in a direction perpendicular to the bearing mechanism 10, thereby pressing or releasing the battery 200. The driving cylinder 4421 can output a constant and precisely controllable pressing force by adjusting the intake pressure, ensuring that the initial conditions and constraint strength of each test are completely consistent, fundamentally guaranteeing the repeatability and comparability of the test data. The fixing platform 23 not only provides a solid installation base for the pressure plate cylinder 22, but also ensures that the entire fixing mechanism 20 itself will not deform or loosen due to impact during subsequent swing tests, providing structural protection for the long-term stable operation of the simulated battery terminal force swing test device 100.

[0023] refer to Figure 5 The fixing mechanism 20 also includes a guide rod 24, which is arranged parallel to the pressure plate cylinder 22. One end of the guide rod 24 is fixedly connected to the pressure plate 21, and the other end passes through the fixing platform 23 and slidably engages with the fixing platform 23, so that the pressure plate 21 moves in a direction perpendicular to the bearing mechanism 10. Through its high-precision engagement with the linear bearing, the guide rod 24 effectively eliminates radial degrees of freedom, ensuring that the pressure plate 21 maintains a strictly perpendicular relationship with the bearing mechanism 10 throughout the entire movement, thereby preventing the pressure plate 21 from jamming due to tilting or scratching the surface of the battery 200.

[0024] refer to Figure 5 The fixing mechanism 20 also includes multiple pressure blocks 25, which are fixed to the bottom surface of the pressure plate 21, i.e., the Y-side, for contact with the battery 200. The pressure blocks 25 are spaced apart along the length of the battery 200, i.e., in the X+-X- direction. These multiple independent pressure blocks 25 are equivalent to multiple independent clamping points. Each pressure block 25 can adapt to its local height to a certain extent, ensuring that the clamping force is evenly distributed across the entire upper surface of the battery 200, avoiding deformation or damage to the battery 200 casing due to localized stress concentration. This provides sufficient stability to resist vibrations from swing tests while avoiding unnecessary over-constraint. The pressure blocks 25 can be made of nylon. Nylon is an excellent electrical insulating material that can physically and completely isolate the electrical connection between the pressure plate 21 and other components and the top of the battery 200, fundamentally eliminating the safety hazard of external short circuits caused by accidental contact of the clamping device during testing. Meanwhile, the nylon material is relatively soft and has a high coefficient of friction. When in contact with the smooth casing of the battery 200, it ensures that the battery 200 will not slip slightly relative to the pressure block 25 under the vibration environment generated by the swing test, thus ensuring the reliability of the fixation. At the same time, its inherent micro-elasticity can absorb some of the high-frequency vibration energy, playing a buffering role and protecting the surface of the battery 200 casing.

[0025] Back Figure 3 The clamping mechanism 30 includes two grippers 31, which can open and clamp relative to the terminal post 210. This ensures that the clamping force is evenly distributed on both opposite sides of the terminal post 210. The clamping force provided by the two grippers 31 generates static friction between the inner surface of the grippers 31 and the outer surface of the terminal post 210, thereby enabling the complex swing trajectory to be accurately transmitted to the terminal post 210, better resisting poor contact caused by vibration, and avoiding significant displacement loss or hysteresis at the interface, ensuring the accuracy of the test input. The grippers 31 can be made of aluminum alloy. Aluminum alloy has a significantly lower density than steel. This makes the grippers 31 lighter, and when driven by the swing mechanism 40 to perform high-frequency, multi-directional movements, the inertia generated is smaller, allowing the grippers 31 to more quickly and accurately reproduce the swing state provided by the swing mechanism 40, improving the control accuracy and dynamic response performance of the simulated battery terminal post force swing test device 100.

[0026] refer to Figure 3 The driving component 442 includes a driving cylinder 4421 and a slide rail 4422. The mounting platform 441 is slidably connected to the slide rail 4422, and the driving cylinder 4421 drives the mounting platform 441 to move along the slide rail 4422. The driving cylinder 4421 can drive the mounting platform 441 to move smoothly back and forth between the first position and the second position, which greatly shortens the waiting time in the test cycle, thereby significantly improving the testing efficiency of the simulated battery terminal force swing test device 100. The slide rail 4422 can strictly limit the degree of freedom of movement of the mounting platform 441, ensuring that it can only slide smoothly along a preset straight trajectory, without any risk of lateral swaying or jamming. This provides a fundamental guarantee for the precise alignment between the clamping mechanism 30 and the battery 200 terminal 210.

[0027] Continue to refer to Figure 3 The avoidance component 44 also includes a buffer structure 443, disposed on the movement path of the mounting platform 441, for buffering the impact of the mounting platform 441 in the first and / or second positions. The mounting platform 441 and the swing mechanism 40 it carries have a large mass and significant inertia when moving at high speed under the drive of the drive cylinder 4421. The buffer structure 443 can effectively absorb this excess kinetic energy at the end of the stroke, converting the violent rigid impact into gentle damping deceleration, thereby allowing the mounting platform 441 to stop smoothly and gently at the preset position. This avoids vibration and rebound caused by hard collisions, and also avoids causing minor displacement or loosening of other components, ensuring the reliability and stability of the long-term operation of the simulated battery terminal force swing test device 100.

[0028] Continue to refer to Figure 3The avoidance component 44 also includes a positioning pin 444 for positioning when the mounting platform 441 moves to the first position. It can be understood that the avoidance component 44 ensures a general movement trajectory through the slide rail 4422 and the drive cylinder 4421, and corrects minor movement and positioning errors through the positioning pin 444. This completely eliminates the positional uncertainty caused by the accumulated error after more than 100 operations of the simulated battery terminal force swing test device, ensuring that the spatial relative position of the clamping mechanism 30 and the battery 200 terminal 210 is consistent during each test.

[0029] refer to Figure 2 The simulated battery terminal force swing test device 100 also includes an electrical connection clamp 60, which is mounted on the stage 50 and electrically connected to the terminal 210 for detecting the resistance of the terminal 210. The electrical connection clamp 60 can continuously and in real-time monitor the resistance change of the terminal 210 while the swing mechanism 40 applies mechanical stress to it. By monitoring the internal resistance change at the connection point of the terminal 210 in real time during the test, the tearing state of the tabs and the reliability of the connection can be effectively determined, providing key test data for the structural design and optimization of the battery 200.

[0030] The platform 50 ensures that core components such as the bearing mechanism 10, fixing mechanism 20, clamping mechanism 30, and swinging mechanism 40 maintain precise relative positions during assembly and long-term use. This ensures accurate alignment of the clamping mechanism 30 and the battery 200 terminal 210 even after highly repeatable testing, avoiding cumulative errors and deformations that may occur when multiple components are installed on different platforms. The platform 50 includes a mounting plane 51, multiple platform columns 52 supported below the mounting plane 51, and adjusting feet 53. The multiple platform columns 52 are rationally distributed with support points below the mounting plane 51, jointly bearing the entire weight of the simulated battery terminal force swing testing device 100 and the dynamic load generated during the test. This effectively disperses the concentrated load, preventing bending deformation of the mounting plane 51 due to insufficient support, and ensuring the flatness and stability of the mounting plane. The adjusting feet 53 are installed below the multiple platform columns 52 and are used to adjust the height of the platform 50. Unevenness is common on the ground in industrial production sites. By rotating the individual adjusting feet 53, local undulations in the ground can be precisely compensated, ensuring that the mounting plane 51 above it is in a strictly level state. This establishes a precise horizontal and height reference for the simulated battery terminal force swing test device 100 mounted on the mounting plane 51, further ensuring accurate alignment between the clamping mechanism 30 and the terminal 210.
