Abstract

The invention relates to a bump test device of audio-video equipment. The bump test device is characterized in that an upper flat plate and a lower flat plate are in sliding connection by a guide rod and a guide sleeve; the upper flat plate is connected with two driving cam mechanisms fixed at the lower surface of the lower flat plate by four driving ejector rods fixed on the lower surface of the upper flat plate; and each driving cam mechanism is in transmission connection with a speed reducer and a motor which are fixed on the lower surface of the lower flat plate by a synchronous belt. The bump test device has the advantages that the requirement on the bump test in safety test of audio, video or similar electronic equipment can be met; bump parameters in different standard requirements can be finished by a group of cam series with different specifications, and the bump accuracy reaches 0.5%; full-automatic bump test is carried out by a mechanical device, the speed and the times of each time of bump can be adjusted, the repeatability can be guaranteed; and moving parts are designed in a reinforced manner, so that the service life of the test device can be guaranteed.

Description

technical field

[0001] The invention relates to an impact test device, in particular to an impact test device suitable for safety detection of audio, video and similar electronic equipment. Background technique

[0002] The impact test is to simulate the impact of the equipment under test, such as bumping or falling, and is used to assess the mechanical strength of the equipment or the impact resistance during transportation. It is widely used in the safety, Performance testing. The impact test device is a test device that applies energy to the device under test in a certain form according to the requirements of the standard, so that the device under test is subjected to impact motion. Different testing standards have different requirements for the parameters of the impact test. The parameters of the impact test mainly include: impact height, angle, material, number of times (or time), frequency, etc. Impact test equipment generally consists of driving components, transmi...
