Background Technology

[0002] Vibration and shock testing is a crucial step in verifying the reliability of energy storage cabinets throughout their entire lifecycle, from production and transportation to use. By simulating the mechanical environment of real-world scenarios and applying controlled vibration or shock forces, the response of the energy storage cabinet and its internal core components, such as battery modules and electrical connectors, is monitored to assess its structural stability, electrical reliability, and safety performance.

[0003] However, some existing test fixtures rely on simple snap-fit ​​or friction positioning, which are prone to loosening due to external forces in vibration environments, leading to displacement of the energy storage cabinet and affecting test accuracy. Furthermore, the limiting components and clamping components of the test fixture need to be adjusted separately, and their positional compatibility is low, making it difficult to synchronously match the size of the energy storage cabinet, resulting in low adjustment efficiency. Utility Model Content

[0023] 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.

[0024] Please see Figures 1-6As shown, the energy storage cabinet vibration and shock testing fixture includes a vibration table 1. Two sets of fixing frames 2 are fixed on the vibration table 1. A long rod 3 is mounted on each fixing frame 2. A limiting mechanism 4 is slidably mounted on the long rod 3. The limiting mechanism 4 includes a support block 402 and a slider 403. The support block 402, slider 403, and locking block 406 are slidably mounted on the long rod 3. The slider 403 is fixedly connected to the support block 402. A rotating rod 401 is rotatably connected to the support block 402. A limiting block 407 is threadedly connected to the rotating rod 401. Rotating the rotating rod 401 on the support block 402 causes the limiting block 407 to slide along the inner wall of the long rod 3 via threaded transmission. As the limiting block 407 gradually slides closer to the long rod 3, it slowly engages with the long rod 3, thus fixing the position of the support block 402. Furthermore, the limiting block 407 and… The long rods 3 are interlocked. A crossbar 5 is fixedly installed on the locking block 406. A clamping mechanism 6 is fixed on the crossbar 5. The part of the long rod 3 that contacts the limiting block 407 is set with an inclined structure. The limiting block 407 is slidably connected to the support block 402. The rotating rod 401 is located on the side wall of the support block 402 away from the crossbar 5. The top of the long rod 3 is provided with a sliding groove 405. A slider 403 is slidably installed in the sliding groove 405. The part of the long rod 3 near the bottom of the slider 403 is set with an arc structure. Two sets of balls 404 are symmetrically arranged in the part of the long rod 3 near the sliding groove 405. The slider 403 and the balls 404 are rolled together. The slider 403 slides smoothly in the sliding groove 405 of the long rod 3. The symmetrically arranged balls 404 between the slider 403 and the long rod 3 reduce friction and make the adjustment process smoother.

[0025] As a technical optimization of this utility model, the clamping mechanism 6 includes a fixing block 604 and a bidirectional screw 605. The top end of the crossbar 5 is fixedly connected to the fixing block 604, and the bidirectional screw 605 is rotatably installed between the two fixing blocks 604. The end of the bidirectional screw 605 is fixedly connected to a handwheel 602. When the handwheel 602 is rotated, the bidirectional screw 605 rotates within the fixing block 604 installed at the top end of the crossbar 5. At this time, the two sliding frames 601 drive the clamping plate 603 to move closer to the energy storage cabinet simultaneously, gradually clamping the energy storage cabinet. The bidirectional screw 605 is threaded with a sliding frame. 601, a clamping plate 603 is fixedly installed on the sliding frame 601. The two sliding frames 601 slide in opposite directions, and the sliding frame 601 and the clamping plate 603 are slidably connected to the crossbar 5. The height of the clamping plate 603 is greater than the height of the long bar 3 and the crossbar 5. The two sets of clamping plates 603 are located at the top of the vibration table 1. The clamping plate 603 slides along the side wall of the crossbar 5. After clamping the energy storage cabinet, if a slight deviation in the position of the energy storage cabinet is found, the position of the energy storage cabinet can be further adjusted by fine-tuning the position of the sliding frame 601 on the crossbar 5 so that its center is aligned with the vibration table 1.

[0026] As a technical optimization of this utility model, the two sets of fixing frames 2 are symmetrically arranged on both sides of the vibration table 1, and the long rod 3 is located at the top of the fixing frame 2. The two sets of fixing frames 2 support the long rod 3, forming a stable frame structure, providing rigid support for the long rod 3, resisting the reaction force during vibration and impact, and ensuring the overall stability of the equipment.

[0027] As a technical optimization of this utility model, an impact mechanism 7 is fixed on the vibration table 1. The impact mechanism 7 includes an impact plate 702 and a guide rod 703. Two guide rods 703 are symmetrically fixedly connected to the vibration table 1. The impact plate 702 is slidably installed on the guide rods 703. Hydraulic rods 701 are fixedly installed on both sides of the vibration table 1. A stop block 704 is fixedly connected to the telescopic end of the hydraulic rod 701. After the impact program is started, the stop block 704 on the hydraulic rod 701 pushes the impact plate 702 up along the guide rod 703 to a preset height according to the set parameters. Then the hydraulic rod 701 resets, and the impact plate 702 falls freely, generating a vertical impact on the energy storage cabinet. At the moment of impact, the force sensor on the impact plate 702 records the peak value of the impact force and the pulse width to ensure that the impact waveform meets the requirements. The stop block 704 abuts against the impact plate 702.

[0028] In use, before testing the energy storage cabinet, the support block 402 is moved to its approximate position along the slide groove 405 of the long rod 3, according to the cabinet's dimensions. The slide groove 405 on the long rod 3 provides guidance for the support block 402, ensuring the accuracy of its movement direction. The rotating rod 401 on the support block 402 is rotated, and the rotating rod 401 drives the limiting block 407 to slide along the inner wall of the long rod 3 via a threaded transmission. As the limiting block 407 gradually slides closer to the long rod 3, it slowly engages with the long rod 3, thus fixing the position of the support block 402. During this process, the slider 403 slides smoothly within the slide groove 405 of the long rod 3, and the slider 403 and the long rod... The symmetrically arranged ball bearings 404 between the two sections reduce friction, making the adjustment process smoother. A locking block 406 is slidably installed inside the long rod 3, and a crossbar 5 is fixed between the two locking blocks 406. Once the position of the support block 402 is determined, the slider 403 drives the crossbar 5 to move synchronously, thereby adjusting the position of the entire crossbar 5 to adapt to the testing requirements of energy storage cabinets of different sizes. The energy storage cabinet is placed stably on the vibration table 1, with the center of the energy storage cabinet aligned as closely as possible with the center of the vibration table 1. Then, the handwheel 602 is turned, and the bidirectional screw 605 rotates within the fixing block 604 installed at the top of the crossbar 5. At this time, the two sliding frames 601 drive the clamping plate 603 to move closer synchronously. The energy storage cabinet is gradually clamped. The clamping plate 603 slides along the side wall of the crossbar 5. After clamping the energy storage cabinet, if a slight deviation in its position is detected, the position of the energy storage cabinet can be further adjusted by fine-tuning the position of the sliding frame 601 on the crossbar 5 to align its center with the vibration table 1. After confirming a stable connection between the vibration table 1 and the energy storage cabinet, the vibration program is started. The vibration table 1 generates sinusoidal, random, or frequency-sweep vibrations according to set parameters, transmitting the vibration force to the energy storage cabinet through the table surface to simulate its vibration environment during transportation, installation, or use. During the test, the vibration is monitored in real time using acceleration sensors, strain gauges, etc., installed at key parts of the energy storage cabinet. The vibration table 1 automatically stops after the set time is reached. After shutting down the equipment, the appearance and electrical performance of the energy storage cabinet are checked, and the test data are recorded for subsequent analysis. After the impact program is started, the block 704 on the hydraulic rod 701 pushes the impact plate 702 up along the guide rod 703 to the preset height according to the set parameters. Then the hydraulic rod 701 is reset, and the impact plate 702 falls freely, generating a vertical impact on the energy storage cabinet. At the moment of impact, the force sensor on the impact plate 702 records the peak value of the impact force and the pulse width to ensure that the impact waveform meets the requirements.
