Description

Technical Field

[0001] This utility model relates to the technical field of battery management testing devices, and in particular to a testing device for a battery management system. Background Technology

[0002] With the booming development of the new energy industry, battery management systems are being used more and more widely in electric vehicles, energy storage power stations and other fields. The performance of the battery management system directly affects the safety, lifespan and overall efficiency of the battery. Therefore, accurate testing of the battery management system is crucial. As a device specifically designed to evaluate the performance of the battery management system, the battery management system testing device needs to be able to adapt to different specifications and types of batteries to meet diverse testing needs. It not only needs to accurately collect parameters such as battery voltage, current and temperature, but also needs to ensure that the battery remains stable and fixed during the testing process to ensure the reliability of the test results. Its performance is of great significance to the development of the new energy industry.

[0003] Currently, common battery management system testing devices often use fixed-size clamps or slot structures to fix batteries. These mechanical structures are usually designed according to the specific battery size. Through the rigid fixing method of mechanical components, the battery is firmly restricted to a preset position. The technical principle is to use the close contact between the clamp and the battery surface and the mechanical locking to prevent the battery from shifting during the testing process, so as to ensure the smooth progress of the testing. In practical applications, this fixing method can achieve the fixing function well when testing batteries of a single size, and provide a certain degree of stability for the testing work.

[0004] However, the existing fixing structure of the testing device has obvious defects. Due to the increasing diversity of battery product specifications, shapes and sizes, traditional fixing methods are difficult to adapt to various battery specifications. When it is necessary to test batteries of different sizes and shapes, the testing personnel often need to replace the entire fixture or make large-scale modifications to the device. The operation process is cumbersome, time-consuming and labor-intensive, which seriously affects the testing efficiency. Moreover, frequent replacement or modification of the fixing device not only increases the equipment maintenance cost, but also causes unstable battery fixing due to installation accuracy issues, which in turn affects the accuracy and reliability of the test results. It is difficult to meet the diversified and efficient testing needs of modern battery management systems. Therefore, a testing device for battery management systems is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a detection device for a battery management system, which aims to improve the problem that the fixing method in the prior art is difficult to adapt to various battery specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A testing device for a battery management system includes a support frame, a partition is provided on the top of the support frame, a battery is provided on the top of the partition, a single testing module is provided on the outer wall of the support frame, an adjustment component is provided on the bottom of the partition, and a moving component is provided on the outer wall of the single testing module.

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a battery management system testing device, comprising a support frame 1, which is welded from high-strength alloy steel and has good rigidity and stability. It is used to support the entire testing device and carry the battery 2 and a single testing module 5. It can withstand greater pressure and weight, and prevent the device from deforming or tipping over during the testing process. A partition 3 is provided on the top of the support frame 1. The surface of the partition 3 is covered with an anti-slip insulating rubber layer to stably place the battery 2. It can increase the friction between the battery 2 and the battery 2 to prevent slippage, and also play an insulating protection role to prevent the battery 2 from directly contacting the support frame 1 and causing a short circuit. The battery 2 is provided on the top of the partition 3. A single testing module 5 is provided on the outer wall of the support frame 1. An adjustment component is provided at the bottom of the partition 3. A moving component is provided on the outer wall of the single testing module 5.

[0035] The adjustment assembly includes a locking post 13 and a locking groove 6 formed inside the support frame 1. The locking groove 6 is a cylindrical blind hole structure with a finely polished inner wall and low surface roughness. It provides precise sliding guidance and limiting space for the locking post 13, ensuring that the locking post 13 can be stably inserted and removed. The outer wall of the locking post 13 is slidably connected to the inside of the locking groove 6. A connecting plate 8 is fixedly connected to the bottom of the partition 3. The connecting plate 8 is a cuboid structure made of high-strength aluminum alloy, which is lightweight and high-strength. It provides an installation foundation and support for the adjustment assembly. The outer wall of the support and the locking post 13 is slidably connected to the inside of the connecting plate 8. The other end of the locking post 13 is fixedly connected to the connecting post 11, and the other end of the connecting post 11 is fixedly connected to the connecting block 10. The outer wall of the connecting block 10 is slidably connected to the inside of the connecting plate 8. The bottom of the connecting block 10 is fixedly connected to the pressing block 9, which is a pressing part with anti-slip texture on the surface, so that the operator can apply force to press it. The outer wall of the connecting post 11 is fitted with a spring 12. One end of the spring 12 is fixedly connected to the outer wall of the locking post 13, and the other end of the spring 12 is fixedly connected to the inner wall of the connecting plate 8.

[0036] Specifically, when placing battery 2, the operator needs to first determine the required adjustment position of separator 3 based on the length, width, and height dimensions of battery 2. The push-button 9 has an anti-slip corrugated surface and its bottom is fitted into the connecting block 10 via a mortise and tenon structure for easy disassembly and maintenance. When the push-button 9 is pressed, the connecting block 10 slides in the T-slot inside the connecting plate 8. The connecting plate 8 is made of high-strength engineering plastic, which has good wear resistance and insulation, ensuring long-term stable operation of the internal sliding structure. The connecting block 10 has guide protrusions on its side, which cooperate with the grooves inside the connecting plate 8 to ensure smooth sliding without deviation. The connecting block 10 is connected to the connecting post 11 via threads. When the connecting block 10 slides, it drives the cylindrical connecting post 11 to move synchronously, thereby causing the end of the connecting post 11... The locking post 13 slides out of the slot 6. The locking post 13 is a frustoconical metal part with a nickel-plated surface to enhance its rust resistance. The slot 6 is a conical blind hole opened on the bracket of the detection device. The two fit together to achieve the limiting function. During the movement of the locking post 13, the spring 12 fitted on the connecting post 11 is compressed. The spring is made of stainless steel and its elastic coefficient has been precisely calculated to ensure that it can be easily pressed to unlock while providing sufficient rebound force. When the partition 3 moves to the position that matches the specifications of the battery 2, the button 9 is released, and the spring 12 rebounds to push the connecting post 11, so that the locking post 13 is re-embedded in the slot 6, and the partition 3 is firmly fixed. The surface of the partition 3 is covered with a honeycomb silicone anti-slip layer, which can increase the friction with the battery 2 and prevent the battery 2 from shaking during the detection process, thereby achieving efficient and stable fixing of batteries 2 of different specifications.

[0037] Reference Figure 1 , Figure 4 and Figure 5The moving assembly includes a slider 14 and a mounting frame 4. The outer wall of the mounting frame 4 is fixedly connected to the outer wall of the support frame 1. A groove 7 is provided inside the mounting frame 4. The inner wall of the groove 7 is anodized, resulting in a smooth and wear-resistant surface, providing a stable sliding track for the slider 14 and ensuring smooth linear movement. The outer wall of the slider 14 is slidably connected to the inside of the groove 7. A limiting groove 15 is provided inside the slider 14, its shape adapted to the friction plate 16, guiding and limiting the movement of the friction plate 16. A single detection module 5 is fixedly connected to the outer wall of the slider 14. The single detection module 5 is bonded to the outer wall of the slider 14 with high-strength epoxy resin adhesive, ensuring it will not loosen or fall off during the detection process. 4. An internal sliding column 17 is connected, and a push rod 18 is fixedly connected to the outer wall of the sliding column 17. The push rod 18 is a straight rod structure with an anti-slip rubber sleeve on the surface, which is convenient for the operator to hold and push. A limit ball 21 is fixedly connected to the outer wall of the sliding column 17. The limit ball 21 is made of hard alloy material and the surface is polished to form a smooth arc surface. It is used to cooperate with the limiting plate 20 to limit and release the friction plate 16. Limiting plates 20 are set on both sides of the limiting ball 21. A friction plate 16 is fixedly connected to the top of the limiting plate 20. The friction plate 16 consists of a two-layer structure. The bottom layer is a high-strength stainless steel plate to provide rigid support. The surface layer is a rubber material with a high coefficient of friction, which is used to generate sufficient friction when in contact with the inner wall of the slide groove 7 to fix the slider 14. The outer wall of the friction plate 16 is slidably connected to the inside of the limiting groove 15. It moves up and down in the limiting groove 15 by the drive of the limiting plate 20. The outer wall of the friction plate 16 is slidably connected to the inside of the limiting groove 15. The limiting groove 15 is in contact with the inner wall of the sliding groove 7. A second spring 19 is provided inside the slider 14. One end of the second spring 19 is fixedly connected to the inner wall of the slider 14, and the other end of the second spring 19 is fixedly connected to one end of the sliding column 17.

[0038] Specifically, when testing the battery management system 2, the corresponding individual testing module 5 must first be removed. During the initial placement, the operator holds the push rod 18, a cylindrical metal rod with anti-slip knurling on its surface for easy pushing. Pushing the push rod 18 causes the connected sliding column 17 to move linearly within the guide sleeve. The sliding column 17 is a hollow tubular structure fitted over the spring 19. As the sliding column 17 moves, the spring 19 is compressed. The spring 19 is made of a high-elasticity alloy material with excellent fatigue resistance, capable of withstanding frequent compression and rebound. Simultaneously, the sliding column 17 moves the limiting ball 21, a smooth-surfaced hard alloy sphere. Its movement releases the limit on the friction plate 16. The friction plate 16 is made of high-strength wear-resistant rubber and a metal base. The slide is made of a composite plate, which provides both sufficient friction and good rigidity. At this time, the slider 14 can slide freely inside the slide groove 7. The slide groove 7 is made of stainless steel and the inner wall is precision polished to ensure that the slider 14 slides smoothly. After the slider 14 is moved to the appropriate position to fit the single detection module 5, the push rod 18 is released, and the spring 19 quickly rebounds, driving the limit ball 21 back to its original position. Since the surface of the limit ball 21 is curved, it pushes the limiting plate 20 to move upward during the reset process. The limiting plate 20 is connected to the friction plate 16 through the linkage mechanism, thereby driving the friction plate 16 to move in the limiting groove 15. Finally, the friction plate 16 is in close contact with the surface of the slide groove 7, which realizes the firm fixation of the slider 14 and ensures that the single detection module 5 remains stable during the detection process, providing a reliable guarantee for accurate detection.

[0039] Working principle: When placing battery 2, press the button 9 according to the specifications of battery 2. The button 9 drives the connecting block 10 to slide inside the connecting plate 8. Then, the connecting block 10 drives the connecting post 11 to move, thereby driving the locking post 13 to slide out from the slot 6. When the locking post 13 moves, it compresses the spring 12, which moves the position of the separator 3. After reaching the appropriate position, release the button 9. The spring 12 rebounds and slides the locking post 13 back into the slot 6, fixing the position of the separator 3. This allows batteries 2 of different specifications to be placed and fixed.

[0040] In addition, during testing, when taking out the corresponding single testing module 5 and placing it, first push the push rod 18, which drives the slide column 17 to move, compressing the second spring 19 and moving the limiting ball 21 to release the limit on the friction plate 16. Then the slider 14 can slide inside the slide groove 7 to the appropriate position. After that, release the push rod 18, and the second spring 19 will rebound to drive the limiting ball 21 back to its original position. Because the surface of the limiting ball 21 is curved, it pushes the limiting plate 20 to move upward, thereby driving the friction plate 16 to move inside the limiting groove 15 and contact the surface of the slide groove 7 for fixation and stability.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
