Embodiment 1

[0064] figure 1 A schematic diagram of the structure of a drop test device provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation where the drop test device is used to perform acceleration compensation during the drop test process. The device can be implemented in the form of software and / or hardware .

[0065] The device in Embodiment 1 of the present invention specifically includes: a drop compensation module 110 and a drop mechanism 120 .

[0066] The drop mechanism 120 is used to drive the test product to fall freely downward during the drop test.

[0067] Preferably, the drop mechanism further includes: a fixing unit;

[0068] A fixing unit is used to fix the test product at a set test angle, so as to realize the directional drop test of the test product;

[0069] Wherein, the fixing unit includes: a clip-type fixing unit, and / or a suction cup-type fixing unit.

[0070] Specifically, during the product drop test process, the ...

Embodiment 2

[0076] figure 2 A schematic structural diagram of a drop test device provided in Embodiment 2 of the present invention. Embodiment 2 of the present invention is optimized on the basis of Embodiment 1, specifically the further optimization of the structure of the drop test device, as shown in figure 2 As shown, the second embodiment of the present invention specifically includes: a drop compensation module 210, a drop mechanism 220, a vertical slide rail 230, a speed detection sensor 240, a controller 250, a vertical lifting component 260, a motor 270, a control line 280 and a support Part 290.

[0077] The drop compensation module 210 is arranged on the upper part of the drop mechanism, and is used to apply a downward force to the drop mechanism when the drop mechanism begins to fall freely, so as to perform acceleration compensation on the drop mechanism, specifically including the first Magnetics, first rail kit and second rail kit to match the vertical rails.

Abstract

The embodiment of the invention discloses drop test equipment, method and device. The equipment comprises a drop compensation module and a drop mechanism, wherein the drop mechanism is used for driving a testing product to freely drop downward in a drop test process; the drop compensation module is arranged at the upper part of the drop mechanism and is used for applying a downward acting force tothe drop mechanism when the drop mechanism starts to freely drop, so as to carry out acceleration compensation on the drop mechanism. According to the embodiment of the invention, the downward actingforce can be applied to the drop mechanism in a drop test, so that the acceleration compensation is carried out on the drop mechanism and loss of an acceleration in the drop test process of the testing product is avoided; the accuracy of the drop test is effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of drop test equipment, in particular to a drop test equipment, method and device thereof. Background technique [0002] At present, in the production process of the product, it is necessary to test the various properties of the product, and determine whether the product is qualified by testing whether the various properties of the product meet the standards. Product drop test is one of the important contents of product performance test. [0003] In the prior art, the drop test of the product is realized by a drop test machine. The drop test machine is equipped with a slide rail and a drop mechanism. The product is placed on the drop mechanism, and the drop mechanism is released by the release mechanism at the test standard height, so that the drop mechanism moves along the Falling on the slide rail to complete the drop test of the product. [0004] However, during the drop of the pro...
