Description

Technical Field

[0001] This utility model relates to the field of battery pack production technology, specifically to a collision testing device for new energy battery packs. Background Technology

[0002] The new energy battery pack collision testing device is mainly used to simulate actual collision scenarios, verify the safety performance of the battery pack under impact, and ensure compliance with the new national standards. It can simulate the continuous compression of the battery pack by the vehicle's own weight, verifying the impact resistance of new materials (such as MPP polypropylene microporous foam). These materials absorb energy through their micron-level pore structure, effectively controlling the temperature difference between the battery cells, and may become the mainstream protection solution after the implementation of the new regulations.

[0003] While traditional new energy battery pack collision devices can verify the safety performance of the battery pack under impact, after a vehicle collision, the internal shell and parts may become sharp, causing a secondary impact on the battery pack. Since new energy battery pack collision devices cannot perform secondary impact tests on the battery pack, this leads to inaccurate test results. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a new energy battery pack collision testing device capable of conducting secondary impact tests on battery packs.

[0005] To address the problems in existing technologies, this utility model provides a new energy battery pack collision testing device, including a main body, a secondary detection component installed inside the main body, a sliding plate slidably connected inside the detection slot, a fixed cylinder fixedly installed inside the detection box and located on both sides of the first electric push rod, a spring rod slidably connected inside the fixed cylinder, and a piercing post slidably connected inside the mounting slot. The secondary detection component includes a detection slot, a sliding plate, a disc, a fixed cylinder, a first electric push rod, a mounting slot, a second electric push rod, a piercing post, and a spring rod. The lower end of the disc is fixedly connected to the upper end of the spring rod, and there is a gap between the lower ends of the disc and the sliding plate. The mounting slot is fixedly opened inside the collision disc, and a set of second electric push rods is fixedly installed inside the mounting slot. The output shaft of the second electric push rod is fixedly connected to the upper end of the piercing post, enabling a secondary impact test on the battery pack.

[0006] Specifically, the first electric push rod is fixedly installed at the lower end of the testing box, and the first electric push rod is located directly below the sliding plate. The testing slot is opened inside the testing box, which makes it easier to clean the residue after the battery pack is tested.

[0007] Specifically, a set of testing boxes is fixedly installed on the main body of the equipment. A set of support frames is fixedly installed on the upper end of the testing boxes. A linear guide rail is fixedly installed on the side wall of the support frame. A slider is slidably connected to the linear guide rail. The slider and a connecting block are fixedly connected. The connecting block is slidably connected to a connecting column. The connecting column is fixedly installed on the testing box. A set of impact plates is fixedly installed on the lower end of the connecting block. A set of manipulators is installed on one side of the main body of the equipment, which enables mechanized battery pack impact tests to be performed under the operation of the operator, ensuring the safety of the operator. Beneficial effects

[0008] 1. In this utility model, after the first impact test, the linear guide rail drives the connecting block to rise, and the second electric push rod is activated. At this time, the second electric push rod will drive the piercing post to move to the outer end of the impact plate. Then, the linear guide rail is activated again to drive the impact plate to perform a second piercing impact test on the battery pack, thereby ensuring the accuracy of the test results.

[0009] 2. In this utility model, the residue left after the battery pack experiment will be located above the sliding plate. Simply activate the first electric push rod to push the residue to the same horizontal plane at the top of the test box, which makes it easy to clean. Attached Figure Description

Example

[0021] like Figures 3-4 The new energy battery pack collision testing device shown includes a main body 1, a secondary detection component 2 installed inside the main body 1, a sliding plate 211 slidably connected inside the detection groove 210, a fixed cylinder 213 fixedly installed inside the detection box 111 and located on both sides of the first electric push rod 214, a spring rod 218 slidably connected inside the fixed cylinder 213, and a piercing post 217 slidably connected inside the mounting groove 215. The secondary detection component 2 includes a detection groove 210, a sliding plate 211, and a disc 212. The device includes a fixed cylinder 213, a first electric push rod 214, a mounting groove 215, a second electric push rod 216, a piercing post 217, and a spring rod 218. The lower end of the disc 212 is fixedly connected to the upper end of the spring rod 218. There is a gap between the lower ends of the disc 212 and the sliding plate 211. The mounting groove 215 is fixedly opened inside the impact disc 117. A set of second electric push rods 216 is fixedly installed inside the mounting groove 215. The output shaft of the second electric push rod 216 is fixedly connected to the upper end of the piercing post 217, which enables a secondary impact test on the battery pack.

[0022] like Figures 1-2 As shown, a set of test boxes 111 are fixedly installed on the main body 1 of the equipment. A set of support frames 112 are fixedly installed on the upper end of the test boxes 111. A linear guide rail 113 is fixedly installed on the side wall of the support frame 112. A slider 114 is slidably connected to the linear guide rail 113. The slider 114 and the connecting block 115 are fixedly connected. The connecting block 115 is slidably connected to the connecting column 116. The connecting column 116 is fixedly installed on the test box 111. A set of collision discs 117 are fixedly installed on the lower end of the connecting block 115. A set of operating machines 110 is installed on one side of the main body 1 of the equipment, which can perform mechanized battery pack impact tests under the operation of the staff to ensure the safety of the staff.

[0023] like Figures 3-4 As shown, after the first impact test, the linear guide 113 is restarted, which will drive the slider 114 to rise. At this time, the second electric push rod 216 is activated, which will drive the piercing post 217 to extend downward. The piercing post 217 will slide to the outside of the collision plate 117. After the piercing post 217 completes its movement, the linear guide 113 is activated. At this time, the linear guide 113 will drive the slider 114 and the connecting block 115 to conduct a second impact test. During the second impact test, the piercing post 217 will pierce into the inside of the battery pack under the action of the collision plate 117, thereby simulating the battery pack being subjected to a second piercing impact from the vehicle's inner shell and parts, thus ensuring the accuracy of the test results.

[0024] Furthermore, when the collision disc 117 impacts the battery pack, the spring rod 218 will slide inside the fixed cylinder due to the impact force, thereby dissipating the force and preventing damage to the sliding plate 211.

[0025] like Figures 1-2 As shown, the operator starts the linear guide 113 by operating the manipulator 110. At this time, the linear guide 113 will drive the slider 114 and the connecting block 115 to slide downward on the connecting column 116. The connecting block 115 will drive the collision disk 117 to move. The lower end of the collision disk 117 will impact the battery pack inside the detection slot 210, thereby conducting an impact test on the battery pack. Example

[0026] like Figures 3-4 As shown, the first electric push rod 214 is fixedly installed at the lower end of the test box 111, and the first electric push rod 214 is located directly below the sliding plate 211. The test groove 210 is opened inside the test box 111, which makes it easier to clean the residue after the battery pack is tested.

[0027] The above-described Embodiment 2 is a further improvement upon Embodiment 1;

[0028] like Figures 3-4 As shown, the detection slot 210 can prevent the battery pack residue from splashing onto the detection box 111 and the test site after being impacted. After the test is completed, the first electric push rod 214 is activated, which will drive the sliding plate 211 to slide upward, thereby pushing the battery pack residue. When the sliding plate 211 moves to the same horizontal plane at the top of the detection box 111, the residue is exposed and can be easily cleaned by the staff.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions in the above embodiments and specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
