Embodiment Construction

[0018] The drop test device of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] see figure 1 and figure 2 , the drop test device 100 of the preferred embodiment of the present invention includes a base 20, a fixed bracket 30, a lifting mechanism 40, a first control member 50, two reset mechanisms 60, a second control member 70 and an operating platform 80.

[0020] The fixing bracket 30 is substantially vertically fixed on the base 20 . The lifting mechanism 40 is fixed on the fixed bracket 30 . Two reset mechanisms 60 are disposed on opposite sides of the base 20 . The first control member 50 and the second control member 70 are respectively fixed on two ends of the same side of the base 20 . The operating platform 80 is fixed on another opposite side of the base 20 . The first control member 50 is used to control the lifting mechanism 40 , and the second control member 70 is used to...

Abstract

The invention discloses a falling test device, which is used for the falling test of a detected piece and comprises a base, a fixed bracket fixed on the base, a first driving member fixed on the fixed bracket and a sliding bracket fixedly connected with the first driving member, wherein the sliding bracket is provided with a lifting arm, the base is provided with a positioning member, the first driving member drives the sliding bracket to slide in relation to the fixed bracket so that one end of the detected piece is lifted while the other end abuts against the positioning member. The sliding bracket of the above falling test device is provided with the lifting arm, and the base is provided with the positioning member, thus one end of the detected piece is lifted by the lifting arm and still remains at the original position after falling, as a result, a plurality of continuous tests are performed on the detected piece by the falling test device.

Description

technical field [0001] The invention relates to a drop test device. Background technique [0002] Small consumer electronic products such as mobile phones, digital cameras, MP3 players, and personal digital assistants (PDAs for short) generally need to undergo drop tests to test the rigidity of these electronic products. In order to improve test efficiency, a drop test device is usually used for testing. [0003] A drop test device includes a base, a bracket, a drop platform and an orientation fixture. The bracket is basically vertically fixed on the base. The drop platform is movably installed on the bracket, and it is a frame structure. The orientation fixture is fixed on the drop table. When performing a drop test on the test piece, first adjust the height of the drop platform as required, then use the directional fixture to clamp the test piece, and finally release the clamp to make the test piece fall from the drop platform. [0004] However, the above-mentioned dr...
