Description

Technical Field

[0001] This utility model relates to the field of electronic product testing technology, and in particular to an electronic product drop test device. Background Technology

[0002] Drop testing of electronic products is a reliability test designed to assess a product's resistance to impact when subjected to accidental drops. This test is crucial for ensuring the safety and durability of products during transportation, handling, and everyday use.

[0003] The purpose of drop testing is mainly to: simulate actual usage conditions, assess the product's ability to withstand accidental impacts by simulating drop scenarios that the product may encounter in daily use; verify product quality, ensure that the product design is robust enough to cope with drops that may occur during transportation or user misoperation; and improve the design by identifying product weaknesses based on test results and optimizing the product structure and packaging design accordingly.

[0004] The existing Chinese patent with publication number CN 206095567 U discloses a drop test device for electronic products, including a base frame. A first support component and a second support component are symmetrically arranged on the upper part of the base frame. The first support component and the second support component are respectively provided with relatively extended support platforms. The first support component and the second support component are respectively provided with upwardly extending insertion blocks. The insertion blocks and the support platforms form an angled shape. The first support component and the second support component are respectively provided with sleeves. The sleeves are mounted on the base frame via a rotating shaft. A torsion spring is fixed on the rotating shaft. The sleeves are provided with receiving grooves to accommodate the two ends of the torsion spring. A pressure block is provided on the base frame to simultaneously drive the two insertion blocks to rotate in opposite directions. A driving cylinder for driving the pressure block and a connecting rod connecting the pressure block and the driving cylinder are provided on the base frame.

[0005] While this patent has the effect of conducting drop tests, it is insufficient to simulate the deviation in drop direction, rotation, or tumbling caused by secondary collisions during a drop. These situations usually have different effects on the product when it is dropped, so the test effect is not comprehensive. Therefore, the inventor has proposed an electronic product drop test device to solve the above-mentioned technical problems. Utility Model Content
