Impact experiment table for testing surface strength of mobile phone

Abstract

The invention relates to the technical field of testing equipment and discloses an impact experiment table for testing the surface strength of a mobile phone. The impact experiment table comprises a bottom support, wherein a supporting rod is movably connected to the upper end of the bottom support, a top support movably is connected to the upper end of the supporting rod, a fixed frame is downwards arranged in the top support, and a testing box is movably connected to the lower end of the fixed frame; an impact spring is arranged in the fixing frame, a center rod is movably connected to the lower end of the impact spring, bearing teeth are arranged on the left side and the right side of the center rod, force storage wheels are connected to the two sides of the bearing teeth in an engagedmode, a control worm is arranged above the front side in the test box, and an adjusting key is connected to the lower portion of the control worm in an engaged mode; the lower portion of the adjustingkey is movably connected with a driving shaft. According to the impact experiment table for testing the surface strength of the mobile phone, the accumulated force of the impact spring can be controlled by controlling the stroke of the center rod, so the purpose of controlling the impact load strength is achieved, and sample requirements can be reduced while a wider data range obtained by experiments is ensured.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an impact test bench for testing the surface strength of a mobile phone. Background technique [0002] Before leaving the factory, electronic products such as mobile phones need to undergo strength tests to verify their drop resistance. Existing tests rely on throwing the mobile phone directly or using a heavy object to impact the surface of the mobile phone. These two methods have great impact on the load control ability Poor, can only guarantee the randomness of the impact, until the impact until the mobile phone is destroyed, the directional and quantitative surface strength cannot be controlled, the obtained experimental data is not reliable enough, and a large number of samples are required, and the cost is high. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a...
