A drop tester capable of simulating continuous drops

Abstract

The invention discloses a drop testing machine capable of simulating continuous drop, which belongs to the technical field of testing and comprises an object stage, a clamping mechanism, a driving mechanism, a support rod group and an eccentric wheel group, and the driving mechanism passes through the eccentric wheel group and the support rod group The transmission connection, the support rod group and the stage are offset. When the prototype to be tested falls from the clamping mechanism to the stage, the support rod group can drive the stage to make an instantaneous downward movement, realizing continuous drop testing. The clamping mechanism includes the second A clamping group, a second clamping group and a horizontal feed mechanism, the horizontal feed mechanism can drive the second clamping group to perform reciprocating feed movement, and cooperate with the first clamping group to clamp or loosen the prototype. The drop testing machine disclosed by the present invention can simulate the continuous drop, which can simulate the continuous drop state by using the clamping mechanism and the instantaneous drop stage, so that the test indicators are richer and more diverse, and it is more convenient to adjust the test height without manual multiple clamping. fast.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a drop testing machine capable of simulating continuous drop. Background technique [0002] All kinds of electronic products may be damaged due to accidents during use. Therefore, major brand manufacturers and component manufacturers around the world have increased product drop tests. Most of the damage to electronic products comes from drop collisions. R&D personnel often spend a lot of time and cost on product-related quality tests. The most common structural tests are drop and impact tests. [0003] Chinese patent document publication number CN208847444U discloses a kind of drop test equipment for electronic products, including a frame, a motor, a transmission assembly, a supporting shaft, a special-shaped wheel, a follower wheel, a push rod, a drop test plate and a side enclosure; There is a side enclosure, the drop test plate is located inside the side enclosure; the ejecto...

Problems solved by technology

[0004] However, the drop test height of the above-mentioned electronic product drop test equipment is single, and it is difficult to meet the detection requirements of the product under test for multiple heights. Moreover, when the user uses the electronic product to drop, it is usually the same electronic product that has different heights. Drop, the above-mentioned electronic product drop test equipment is difficult to simulate the drop situation, and the drop detection results are relatively simple
