Description

Technical Field

[0001] This utility model relates to the field of battery protection technology, specifically to a battery protection frame impact resistance testing device. Background Technology

[0002] The battery protection framework is a systematic protection system to ensure the safe operation of batteries. Through the collaboration of hardware, software, and algorithms, it prevents risks such as overcharging, over-discharging, short circuits, and high temperatures. Its core components consist of three layers. First, hardware protection relies on components such as protection chips, fuses, and temperature sensors in the battery management system to monitor voltage, current, and temperature in real time, immediately cutting off the circuit when safety thresholds are exceeded. Second, software algorithms dynamically adjust charging and discharging power by accurately calculating remaining charge and health status, preventing the battery from operating under extreme conditions for extended periods. Finally, structural protection employs insulating materials and explosion-proof housings to physically isolate the battery cells from external impacts and compression, while also preventing electrolyte leakage.

[0003] Current assessments of battery protection frames still largely rely on the inherent properties of their constituent materials, such as the temperature resistance of the insulation layer and the corrosion resistance of the casing. However, in real-world applications, batteries frequently face unexpected impacts and crushing forces, and existing assessment systems lack targeted impact resistance testing devices. This lack of such devices makes it impossible to simulate the stress conditions under real-world collisions. It hinders the accurate quantification of the frame's deformation and breakage threshold under impact, and fails to visually demonstrate its protective effect on the internal battery cells. Consequently, impact resistance assessments remain theoretical, disconnected from actual safety requirements, potentially posing a risk to the safe operation of batteries under complex conditions. Summary of the Invention

[0004] To solve the above-mentioned problems, this utility model proposes a battery protection frame impact resistance testing device that can intuitively test the impact resistance of the battery protection frame and generate specific data.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a battery protective frame impact resistance testing device, comprising: Base plate; The test seat is slidably mounted on the base plate and can be fixed. A U-shaped vertical plate is fixedly mounted on it, and a pressure detection seat is fixedly mounted on the inner side of the U-shaped vertical plate. The impact hammer is slidably mounted on the test seat and is detachable. It is positioned towards the pressure detection seat and forms a battery protection frame placement area with the pressure detection seat. The driving mechanism includes a pusher block and an electromagnetic transmitter. The pusher block is slidably mounted on the base plate and faces the impact hammer. The electromagnetic transmitter is fixedly mounted on the base plate and pushes the pusher block closer to the impact hammer.

[0006] Furthermore, anti-slip feet are fixed at the four corners of the bottom surface of the base plate.

[0007] Furthermore, the bottom surface of the test seat is symmetrically provided with a slide bar, the base plate is provided with a slide groove matching the slide bar, and the base plate is provided with a plurality of fixing holes at equal intervals on one side of the slide groove. The test seat is fixed to the base plate by screws passing through the fixing holes.

[0008] Furthermore, several reinforcing frames are fixedly provided between the side wall of the U-shaped vertical plate and the test seat.

[0009] Furthermore, a support plate is slidably provided on the test seat, and a guide groove matching the support plate is provided on the test seat. The two sides of the support plate are slidably disposed in the guide groove, and the impact hammer is fixedly disposed on the support plate by screws.

[0010] Furthermore, a guide rail for matching the push block is fixedly provided on the base plate, and the bottom surface of the push block is provided with a groove for matching the guide rail.

[0011] Compared with existing technologies, this invention has the following advantages: the device achieves intuitive testing and data quantification of impact resistance through the cooperation of a pressure detection seat, a drive mechanism, and an impact hammer. The pressure detection seat is fixed to the inner side of the reinforced U-shaped vertical plate, ensuring structural stability and accurate acquisition of impact force data. The electromagnetic transmitter drives the push block to move linearly along the guide rail, which in turn drives the impact hammer to precisely impact the battery protection frame in the placement area. The guide rail and the groove cooperate to ensure stable impact force direction and efficient transmission of driving force. The test seat is positioned by a sliding groove and locked by a fixing hole, ensuring accurate test conditions and eliminating the influence of positional deviation on the data. Impact hammers of different specifications can be easily replaced to adapt to multiple testing scenarios. The pressure detection seat converts the impact force into specific data, achieving an intuitive and quantitative assessment of impact resistance. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] Combined with appendix Figure 3 Appendix Figure 4 A battery protection frame impact resistance testing device includes: a base plate 1, wherein anti-slip feet 8 are fixedly provided at the four corners of the bottom surface of the base plate 1, which can increase the friction between the device and the ground, prevent the device from shifting due to impact force during testing, and ensure the stability of the test position. At the same time, it can also reduce the damage to the ground caused by device vibration and improve the safety of use.

[0016] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 4 The test seat 2 is slidably mounted on the base plate 1 and can be fixed in place. The bottom surface of the test seat 2 is symmetrically provided with a slide bar 9. The base plate 1 has a sliding groove 10 that matches the slide bar 9. Several fixing holes 11 are equidistantly provided on one side of the sliding groove 10 on the base plate 1. The test seat 2 is fixed to the base plate 1 by screws passing through the fixing holes 11. The cooperation between the slide bar 9 and the sliding groove 10 allows the test seat 2 to slide smoothly along the base plate 1, facilitating adjustment of the test seat 2's position to adapt to different testing needs. The fixing holes 11, combined with the screws, can precisely lock the position of the test seat 2, ensuring accurate positioning for each test and improving the accuracy of test data.

[0017] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 A U-shaped vertical plate 3 is fixedly mounted on the test base 2. A pressure detection seat 4 is fixedly mounted on the inner side of the U-shaped vertical plate 3. Several reinforcing brackets 12 are fixed between the side wall of the U-shaped vertical plate 3 and the test base 2 to enhance the structural strength of the U-shaped vertical plate 3 and prevent it from deforming when subjected to the force transmitted by the impact hammer 5. This ensures the stability of the pressure detection seat 4 and guarantees accurate and reliable pressure detection data.

[0018] Combined with appendix Figure 1 Appendix Figure 2 The impact hammer 5 is slidably mounted on the test base 2 and is detachable. It faces the pressure detection base 4, forming a battery protection frame placement area with the pressure detection base 4. A support plate 13 is slidably mounted on the test base 2, and a guide groove 14 is provided on the test base 2 to match the support plate 13. The two sides of the support plate 13 are slidably positioned within the guide groove 14. The impact hammer 5 is fixed to the support plate 13 with screws. The support plate 13, in conjunction with the guide groove 14, enables precise movement of the impact hammer 5, ensuring the accuracy of the measurement results. The impact hammer 5 is fixed to the support plate 13 with screws, making assembly and disassembly convenient and facilitating the replacement of different specifications of impact hammer 5 to simulate different impact scenarios.

[0019] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3The driving mechanism includes a pusher block 6 and an electromagnetic transmitter 7. The pusher block 6 is slidably mounted on the base plate 1 and faces the impact hammer 5. The electromagnetic transmitter 7 is fixedly mounted on the base plate 1 and pushes the pusher block 6 closer to the impact hammer 5. A guide rail 15 matching the pusher block 6 is fixedly provided on the base plate 1. The bottom surface of the pusher block 6 has a groove matching the guide rail 15, which can limit the movement trajectory of the pusher block 6, ensuring that the pusher block 6 pushes the impact hammer 5 in a straight line and avoids deviation of the impact force direction due to the offset of the pusher block 6. At the same time, it improves the smoothness of the sliding of the pusher block 6 and ensures that the driving force of the electromagnetic transmitter 7 can be efficiently transmitted to the impact hammer 5.

[0020] The specific implementation method of this utility model is as follows: In use, first place the device on a flat ground through the anti-slip feet 8 on the bottom surface of the base plate 1 to avoid displacement during testing. Then push the test base 2 so that its bottom slide bar 9 slides along the slide groove 10 of the base plate 1. After adjusting to a suitable test position, use screws to pass through the fixing holes 11 between the test base 2 and the base plate 1 to lock the test base 2.

[0021] Then place the battery protection frame between the impact hammer 5 and the pressure detection seat 4. If the impact hammer 5 needs to be replaced, the screws on the support plate 13 can be removed. After replacement, the new impact hammer 5 can be fixed on the support plate 13 with screws to ensure that the impact hammer 5 is facing the protection frame.

[0022] Connect the device to an external power source and start the electromagnetic transmitter 7. The transmitter pushes the push block 6 to slide linearly along the guide rail 15 of the base plate 1. The push block 6 strikes the impact hammer 5, which in turn impacts the battery protection frame. The pressure detection seat 4 collects the impact force data in real time, thus completing one impact resistance test.
