Description

Technical Field

[0001] The present application relates to the technical field of battery puncture testing, and in particular to a vehicle puncture detection system. Background Art

[0002] Batteries are the core components of new energy vehicles, and their safety performance is related to the reliability of the entire vehicle and the safety of users. Among them, lithium-ion batteries are widely used due to their high energy density, but under the conditions of collision, extrusion or puncture, the battery is prone to diaphragm rupture, positive and negative short circuits and other faults, causing thermal runaway and leading to fire and explosion. Therefore, reliability testing of batteries is a key link before new energy vehicles leave the factory.

[0003] The needle penetration test is a common method for testing battery safety performance. By piercing the battery with a steel needle to trigger an internal short circuit, it can effectively evaluate the battery's ability to suppress thermal runaway and the effectiveness of the protection design. When performing a needle penetration test on a battery pack, a step-by-step operation is usually adopted: the battery pack is disassembled and placed in an open environment for testing, and then external equipment is used to simulate submersion in water to dissipate heat or extinguish a fire. This type of method has a relatively delayed emergency response, lacks operational safety, and has high labor costs.

[0004] Therefore, there is an urgent need for a highly safe, human resource-saving acupuncture test system that can improve test efficiency while reducing overall costs. Summary of the invention

After the test is completed, the puncture device is removed, and then the sample height is lowered so that the lifting frame falls on the submerged frame, and the submerged frame is lowered by a driving assembly to submerge the sample, thereby requiring less manpower and improving the defects of high cost and insufficient safety of the puncture test equipment.

[0015] By adopting the above technical solution, when performing a bottom needle penetration test on a new energy vehicle battery pack, the position of the bottom plate on the ground rail is determined by a roller, and then the top plate is pressed down to make the first electromagnet contact the ground rail, so that the first electromagnet is energized, thereby locking the position of the bottom plate;

[0016] Move the mounting plate on the slide rail to determine the position of the mounting plate, then install the steel needle on the clamping assembly, start the first cylinder, push the steel needle into the battery pack, and after the puncture test is completed, start the first cylinder to lower the clamping assembly, turn off the first electromagnet, and the base plate can be moved to the next required position.

[0017] Optionally, a panel is provided between the top plate and the bottom plate, the driving bolts penetrate the panel, the panel is fixed to the bottom plate by studs, and the guide column penetrates the panel and is slidably connected to the panel.

[0018] By adopting the above technical solution, the setting of the enclosure not only plays a role in limiting the top plate, but also improves the stability of the top plate, the guide column and the first electromagnet.

[0022] If the steel needle needs to be pulled out, the connecting seat is directly lowered; if the steel needle needs to be left in the battery pack for further observation, the cylinder can be started to separate the clamping block from the connecting tube, and then the connecting seat is lowered. The chuck and the connecting column will remain under the battery pack together with the steel needle, making the post-processing plan of the puncture test selectable, thereby improving the test efficiency.

[0023] Optionally, a connecting block is provided on the connecting seat, and the connecting block is connected to the inclined launch well through a torsion spring. When the bottom of the inclined launch well is in full contact with the connecting seat, the torsion spring is in a natural state.

[0087] The implementation principle of a vehicle puncture detection system in an embodiment of the present application is as follows: when performing a puncture test on a battery pack of a new energy vehicle, the submerged part 15 is raised to the surface of the water through the second rope winding machine 20. First, use a crane or a forklift to move the test object to the lifting frame 12 and fix it, and lock the four corners of the lifting frame 12 with the lifting head 10. Use the elevator 3 to raise the lifting frame 12, and use the first rope winding machine 2 to drag the bottom plate 23 to determine the position of the bottom plate 23 on the ground rail 21, and then press the top plate 32 down through the handle 40 to make the first electromagnet 39 contact the ground rail 21, so that the first electromagnet 39 is energized, thereby locking the position of the bottom plate 23.

[0088] The lead screw 28 is started, and the output shaft of the lead screw 28 drives the threaded block 29 to move, thereby driving the mounting plate 31 to move on the slide rail 25. After determining the position of the mounting plate 31, the chuck 58 is used to clamp the steel needle, and the second electromagnet 52 is energized to fix the positions of the vertical launch well 70 and the oblique launch well 71. The second cylinder 84 is started to push the clamping block 85 into the first clamping groove 61, and the clamping piece 64 is inserted into the third clamping groove 86. The first cylinder 42 is started to raise the clamping assembly, and the steel needle is inserted into the battery pack.

[0089] If the steel needle needs to be pulled out, the first cylinder 42 is activated to lower the clamping assembly. If the steel needle needs to be left in the battery pack, the second cylinder 84 is activated to separate the clamping block 85 from the connecting tube 54, and then the clamping assembly is lowered, so that the clamp 58, the protective cover 56, the second base 55, the connecting column 62 and the steel needle are left under the battery pack.

[0090] When the steel needle is too long, an escape state can be adopted. After pulling out the needle, the first electromagnet 39 and the second electromagnet 52 are powered off. In the process of pulling the bottom plate 23, the steel needle encounters an obstacle, and the oblique launch well 71 flips over a certain angle to avoid danger. The vertical launch well 70 rises under the lifting of the limit block 59. After the escape is completed, the oblique launch well 71 is reset under the action of the tension spring, and the vertical launch well 70 is reset under the action of the third spring 80.

[0091] After the acupuncture test is completed, the first cylinder 42 is started to lower the clamping assembly, the first electromagnet 39 is turned off, and the bottom plate 23 is pulled to the required position by the first rope winding machine 2. After the acupuncture device is withdrawn from under the sample, the lifting frame 12 is lowered by the elevator 3. After the lifting frame 12 contacts the sinking part 15, the lifting assembly on the elevator 3 continues to descend, the lifting head 10 is separated from the lifting groove 13, and the rotating arm 9 is rotated under the action of the first spring 11 and is pulled out from under the lifting frame 12.

[0092] The vehicle puncture test system provided by the present application can quickly fix the test sample and remotely operate the test, requiring less manpower and ensuring the safety of personnel, thereby improving the defects of high cost and insufficient safety of puncture test equipment.

[0093] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
