Description

Technical Field

[0001] The utility model belongs to the field of lead-acid battery impact resistance detection, and in particular relates to a lead-acid battery impact resistance test device. Background Art

[0002] In order to meet the different requirements of the market, lead-acid batteries have more and more physical performance requirements in addition to meeting the power supply requirements of the vehicle power system. Because the battery is fixed to the battery tray by bolts when used on the vehicle, the battery tray is generally fastened to the vehicle body with bolts. After the battery is fixed to the battery tray, if the bolts become loose during use, there may be contact impact between the bolts and the bottom of the battery during driving. If the impact resistance of the bottom of the battery is poor, long-term impact will cause leakage from the bottom of the battery, causing customer complaints.

[0003] In order to better fit the whole vehicle application, some customers have higher requirements for impact testing. The existing impact resistance test is: place an ordinary nut with a diameter of M8 on the test bench, then the operator lifts the battery to a certain height, and then let the battery fall freely to collide with the ordinary nut with a diameter of M8 placed on the test bench. This test is repeated 5 times at different parts of the bottom of the battery. It is required that the bottom of the tank should not be penetrated and tested with PH test paper, and there should be no leakage and seepage of electrolyte. The main problem with the current test method is that when the battery falls from a high place, it is mainly to manually lift the battery to a certain height, and then the battery will impact the nut through free fall. Due to manual operation, it is impossible to ensure that the battery can fall completely vertically and freely, and it often tilts, causing the battery to contact the test bench first in the process of free fall, causing the battery outer tank to deform or the bottom of the battery tank to not fully withstand the impact of the nut, making the test result less accurate and unable to accurately reflect the battery's impact resistance. Summary of the invention
