Description

Technical Field

[0001] This utility model relates to the field of battery performance testing technology, specifically to an adjustable tooling device for battery module testing. Background Technology

[0002] During the testing of battery modules, a top water-cooled heat dissipation structure is often used for temperature control. A water-cooled thermal pad is placed on top of the battery module to maximize the efficiency of planar heat dissipation, thereby suppressing the risk of thermal runaway and extending battery life. Precise heat dissipation testing is used to verify the performance of the thermal management system under real-world conditions, ensure temperature uniformity, and improve the reliability of test data to meet the stringent requirements for battery safety. A heavy object is needed to press down on the water-cooled thermal pad to ensure that the water-cooled thermal pad is in contact with the top of the module as much as possible.

[0003] Currently, the common method for pressing water-cooled thermal pads involves wrapping them with bricks of arbitrary weight and pressing them down. However, the direct pressure from these heavy objects makes it impossible to quantify the pressure value, resulting in uneven distribution and poor adhesion between the thermal pad and the battery module surface. This severely affects heat dissipation uniformity, directly leading to inaccurate test data and impacting battery performance evaluation. Therefore, those skilled in the art provide an adjustable fixture for battery module testing to address the problems mentioned in the background. Utility Model Content

A plurality of protection components are uniformly fixed in an array on the lower surface of the lifting plate.

[0008] As a preferred embodiment of the above technical solution, the limiting component includes a slot formed on one side wall of the fixed block. A support plate is fixedly connected to the lower end of the lifting plate. A sliding cavity is formed inside the support plate. Multiple telescopic springs are fixedly connected to the inner wall of the sliding cavity away from the spring damper. A locking block is slidably connected inside the sliding cavity. The front ends of the multiple telescopic springs are fixedly connected to one side of the locking block. The front end of the locking block is wedge-shaped and penetrates the inner wall of one side of the sliding cavity. The front end of the locking block engages with the slot. A moving rod penetrates one side of the fixed block. One end of the moving rod is fixedly connected to one side of the locking block.

[0009] As a preferred embodiment of the above technical solution, the adjustment assembly includes an adjustment cavity and a motor. The adjustment cavity is located within a placement plate.

The output end of the motor passes through the placement plate and is fixedly connected to one end of the threaded rod. A movable plate is slidably connected within the adjustment cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By fixing the battery module to the top of the placement plate and installing a water-cooled thermal pad on top of the battery module, the hydraulic cylinder drives the pressing plate to descend. The pressing plate applies more uniform pressure to the water-cooled thermal pad. With the help of a pressure sensor to monitor the applied pressure in real time, the water-cooled thermal pad can be tightly attached to the surface of the battery module, resulting in uniform heat dissipation of the battery module, better water cooling effect, improved accuracy of test data, and more accurate evaluation of battery performance.

[0013] 2. The motor drives the threaded rod to rotate, which adjusts the distance between the second vertical guide rail and the first vertical guide rail, thereby adjusting the position of the pressing plate above the placement plate and adjusting the pressing area of ​​the pressing plate. This allows the device to press battery modules of different lengths, ensuring uniform pressure distribution.

[0014] 3. By setting a spring damper between the pressing plate and the lifting plate, the pressing plate can slowly and evenly apply pressure to the water-cooled thermal pad through the buffering effect of the spring damper. This ensures that the water-cooled thermal pad can slowly and tightly adhere to the surface of the battery module, avoiding the impact or damage to the water-cooled thermal pad and the battery module caused by excessive pressure at one moment. This uniform adhesion helps to protect the structural integrity of the battery module and the water-cooled thermal pad, thereby ensuring more stable temperature control of the battery module during the test.

[0015] 4. After the spring damper retracts a certain distance, the support plate and the slot cooperate with the locking block to mechanically lock the fixing block at the front end of the spring damper. This can fix the relative position and pressure value between the pressing plate and the lifting plate. This locking mechanism helps to keep the pressure applied by the pressing plate to the water-cooled heat-conducting pad stable and avoid pressure fluctuations caused by external factors. The stable pressure environment makes the detection of the pressure at the front end of the pressing plate more accurate, thereby improving the reliability of battery performance test data.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-4 This utility model provides a technical solution: an adjustable tooling device for testing battery modules, including a placement plate 1 for placing battery modules, a first vertical guide rail 2 fixedly connected to one side of the upper end of the placement plate 1, a second vertical guide rail 3 installed on the other side of the placement plate 1, a pressing component 4 for pressurizing the battery modules installed between the first vertical guide rail 2 and the second vertical guide rail 3, a plurality of protective components 5 for protecting the battery modules installed inside the pressing component 4, an adjusting component 6 for adjusting the pressing component 4 installed inside the placement plate 1, and the second vertical guide rail 3 installed inside the adjusting component 6.

[0024] As one implementation method in this embodiment, please refer to Figures 1-2As shown, the pressing component 4 includes lifting blocks 401, and two lifting blocks 401 are provided. The two lifting blocks 401 are slidably connected to the outside of the first vertical guide rail frame 2 and the second vertical guide rail frame 3 respectively. The lower end of the lifting block 401 on the first vertical guide rail frame 2 is slidably fitted with a lifting plate 402. One end of the lifting plate 402 is fixedly connected to the side wall of the lifting block 401 on the second vertical guide rail frame 3. Hydraulic cylinders 403 are fixedly installed at the upper center of the first vertical guide rail frame 2 and the second vertical guide rail frame 3 respectively. The output ends of the two hydraulic cylinders 403 pass through the first vertical guide rail frame 2 and the second vertical guide rail frame 3 respectively, and the output ends of the two hydraulic cylinders 403 are fixedly connected to the upper end face of the two lifting plates 402 respectively. Multiple protection components 5 are uniformly fixed in an array on the lower end face of the lifting plate 402. The lower end of the multiple protection components 5 is jointly installed with a pressing plate 404. Multiple pressure sensors 405 are arrayed at the lower end of the pressing plate 404.

[0025] Furthermore, by fixing the battery module to the upper end of the placement plate 1 with bolts, and installing a water-cooled heat-conducting pad above the battery module, the output ends of the two hydraulic cylinders 403 synchronously push the lifting block 401 to descend, the lifting plate 402 to descend, and the pressing plate 404 to descend. The pressing plate 404 applies pressure to the water-cooled heat-conducting pad. The lifting and lowering of the dual hydraulic cylinders 403 makes the pressure applied by the pressing plate 404 more uniform. In conjunction with the pressure sensor 405 at the bottom of the pressing plate 404, the applied pressure is monitored in real time, making it easy for users to observe the pressure applied by the pressing plate 404 and record the test data. The pressure applied by the pressing plate 404 allows the water-cooled heat-conducting pad to be tightly attached to the surface of the battery module, ensuring uniform heat dissipation of the battery module by the water-cooled heat-conducting pad, better water cooling effect, improved accuracy of test data, and more accurate evaluation of battery performance.

[0026] As one implementation method in this embodiment, please refer to Figure 1 and Figure 3 As shown, the protection component 5 includes a spring damper 501 and a fixing block 502. The spring damper 501 is fixedly connected to the lower end of the lifting plate 402, and the fixing block 502 is fixedly connected to the upper end of the pressing plate 404. The front end of the spring damper 501 is fixedly installed on the upper end of the fixing block 502, and limit components are symmetrically arranged on both sides of the fixing block 502.

[0027] Furthermore, when the pressing plate 404 applies pressure to the water-cooled thermal pad, a spring damper 501 is provided between the pressing plate 404 and the lifting plate 402 to provide a buffering effect, so that the pressing plate 404 can slowly and evenly apply pressure to the water-cooled thermal pad, ensuring that the water-cooled thermal pad can slowly and tightly adhere to the surface of the battery module. This can avoid the impact or damage to the water-cooled thermal pad and the battery module caused by excessive pressure in an instant. This uniform adhesion helps to protect the structural integrity of the battery module and the water-cooled thermal pad, thereby ensuring more stable temperature control of the battery module during the test.

[0028] As one implementation method in this embodiment, please refer to Figure 3 As shown, the limiting component includes a slot 503, which is formed on one side wall of the fixed block 502. A support plate 504 is fixedly connected to the lower end of the lifting plate 402. A sliding cavity 505 is formed inside the support plate 504. Multiple telescopic springs 506 are fixedly connected to the inner wall of the sliding cavity 505 away from the spring damper 501. A locking block 507 is slidably connected inside the sliding cavity 505. The front ends of the multiple telescopic springs 506 are all fixedly connected to one side of the locking block 507. The front end of the locking block 507 is wedge-shaped. The front end of block 507 penetrates the inner wall of one side of sliding cavity 505, and the front end of block 507 and slot 503 are engaged. A moving rod 508 penetrates one side of fixed block 502. One end of moving rod 508 is fixedly connected to one side of block 507. A metal block 509 is fixedly connected to the end of moving rod 508 away from block 507. A connecting plate 510 is fixedly connected to the lower end of lifting plate 402. An electromagnet 511 is fixedly installed on the lower side of connecting plate 510. The electromagnet 511 is directly opposite the metal block 509.

[0029] Furthermore, when the spring damper 501 contracts a certain distance, the fixing block 502 at the front end of the spring damper 501 will contact the front end of the locking block 507. Since the front end of the locking block 507 is wedge-shaped, the wedge-shaped surface will decompose the pressure, thereby causing the telescopic spring 506 to contract. The front end of the locking block 507 will temporarily contract into the sliding cavity 505. When the upper end of the pressing plate 404 contacts the lower end of the support plate 504, the pressing plate 404 will stop sliding due to the limitation of the support plate 504. At this time, the locking groove 503 on one side of the fixing block 502 is aligned with the locking block 507. The telescopic spring 506 will then reset, and the front end of the locking block 507 will move into the locking groove 503. Therefore, the lower end surface of the support plate 504 and the locking block 507 will cooperate with the locking groove. 503 can achieve mechanical locking of spring damper 501, which can fix the relative position and pressure value between pressing plate 404 and lifting plate 402. This locking mechanism helps to keep the pressure applied by pressing plate 404 to water-cooled heat-conducting pad stable and avoid pressure fluctuations caused by external factors. The stable pressure environment makes the pressure sensor 405 more accurate in detecting the pressure at the front end of the pressing plate, thereby improving the reliability of battery performance test data. When pressing plate 404 is reset, electromagnet 511 starts to work. Electromagnet 511 attracts metal block 509, thereby causing telescopic spring 506 to contract and the front end of locking block 507 to move out of locking slot 503. At this time, spring damper 501 can automatically reset.

[0030] As one implementation method in this embodiment, please refer to Figure 1 and Figure 4As shown, the adjustment assembly 6 includes an adjustment cavity 601 and a motor 602. The adjustment cavity 601 is opened inside the placement plate 1. A threaded rod 603 is rotatably connected to the inner wall of the adjustment cavity 601. The output end of the motor 602 passes through the placement plate 1 and is fixedly connected to one end of the threaded rod 603. A movable plate 604 is slidably connected inside the adjustment cavity 601. The threaded rod 603 passes through the center of the movable plate 604 and is threadedly connected to the outer movable plate 604. Two symmetrically arranged movable openings 605 are opened at the top of the inner wall of the adjustment cavity 601. The two movable openings 605 extend to the outside and communicate with the outside. A second vertical guide rail 3 is slidably connected inside the two movable openings 605, and the lower end of the second vertical guide rail 3 is fixedly connected to the upper end of the movable plate 604.

[0031] Furthermore, the distance between the second vertical guide rail 3 and the first vertical guide rail 2 can be adjusted according to the length of the battery module. The motor 602 drives the threaded rod 603 to rotate, the moving plate 604 slides in the adjustment cavity 601, and the second vertical guide rail 3 slides in the moving port 605, thereby realizing the adjustment of the distance between the second vertical guide rail 3 and the first vertical guide rail 2. At the same time, the lifting plate 402 slides below the lifting block 401 located on the first vertical guide rail 2, thereby realizing the adjustment of the pressing area of ​​the pressing plate 404, so that the device can press battery modules of different lengths and ensure uniform pressure distribution.

[0032] As one implementation method in this embodiment, please refer to Figure 1 As shown, a display screen body 7 is fixedly installed on one side of the upper end of the lifting plate 402, and the lower end surface of the placement plate 1 is provided with anti-slip texture.

[0033] Furthermore, the display body 7 is existing technology. When the display body 7 receives a signal, it converts it into a corresponding electrical signal and applies it to the liquid crystal layer to ensure that the image can be displayed clearly. The pressure sensor 405 can convert the sensed pressure into an electrical signal. After processing, the electrical signal is transmitted to the circuit board of the display body 7 to display the pressure value. This will not be elaborated further here. The protective texture increases the friction between the placement plate 1 and the placement surface, thereby improving the stability of the device.

[0034] Working principle: The battery module is fixedly installed on the upper end of the placement plate 1, and a water-cooled heat-conducting pad is installed above the battery module. Then, the distance between the second vertical guide rail 3 and the first vertical guide rail 2 needs to be adjusted according to the length of the battery module. The motor 602 drives the threaded rod 603 to rotate, and the moving plate 604 slides in the adjustment cavity 601. The second vertical guide rail 3 slides in the moving port 605, thereby adjusting the distance between the second vertical guide rail 3 and the first vertical guide rail 2. At the same time, the lifting plate 402 slides below the lifting block 401 located on the first vertical guide rail 2, thereby adjusting the pressing area of ​​the pressing plate 404. This allows the device to press battery modules of different lengths, ensuring uniform pressure distribution. After adjustment, The output ends of the two hydraulic cylinders 403 synchronously push the lifting block 401 down, the lifting plate 402 down, and the pressing plate 404 down. The pressing plate 404 applies pressure to the water-cooled heat-conducting pad. The lifting and lowering of the two hydraulic cylinders 403 makes the pressure applied by the pressing plate 404 more uniform. In conjunction with the pressure sensor 405 at the bottom of the pressing plate 404, the applied pressure is monitored in real time, making it easy for users to observe the pressure applied by the pressing plate 404 and record the test data. The pressure applied by the pressing plate 404 ensures that the water-cooled heat-conducting pad can be tightly attached to the surface of the battery module, ensuring uniform heat dissipation of the battery module by the water-cooled heat-conducting pad, better water cooling effect, improved accuracy of test data, and more accurate evaluation of battery performance. When the pressing plate 404 applies pressure to the water-cooled heat-conducting pad... A spring damper 501 is installed between the pressing plate 404 and the lifting plate 402 to provide a buffering effect, allowing the pressing plate 404 to slowly and evenly apply pressure to the water-cooled heat-conducting pad. This ensures that the water-cooled heat-conducting pad and the surface of the battery module can slowly and tightly adhere to each other, preventing excessive pressure from impacting or damaging the water-cooled heat-conducting pad and the battery module. This even adhesion helps protect the structural integrity of the battery module and the water-cooled heat-conducting pad, thereby ensuring more stable temperature control of the battery module during testing. When the spring damper 501 retracts a certain distance, the fixing block 502 at the front end of the spring damper 501 will contact the front end of the locking block 507. Since the front end of the locking block 507 is wedge-shaped, the wedge-shaped surface decomposes the pressure, thereby allowing the extension spring 506 to... When the locking block 507 retracts, its front end temporarily retracts into the sliding cavity 505. When the upper end of the pressing plate 404 contacts the lower end of the support plate 504, the pressing plate 404 stops sliding due to the limiting effect of the support plate 504. At this time, the slot 503 on one side of the fixing block 502 is aligned with the locking block 507. The telescopic spring 506 then resets, and the front end of the locking block 507 moves into the slot 503. Therefore, the lower end face of the support plate 504 and the locking block 507, in conjunction with the slot 503, can achieve mechanical locking of the spring damper 501, fixing the relative position and pressure value between the pressing plate 404 and the lifting plate 402. This locking mechanism helps maintain a stable pressure applied by the pressing plate 404 to the water-cooled heat-conducting pad, avoiding pressure fluctuations caused by external factors.A stable pressure environment allows the pressure sensor 405 to more accurately detect the pressure at the front end of the pressure plate, thereby improving the reliability of battery performance test data.

[0035] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
