Abstract

The utility model provides a portable test machine for product falling off, which has a sliding platform on a base, a carrier on the sliding platform and a test seat on the carrier. A sensor beside could do location surveillance for the carrier or the test seat on which a power device and a bracket are locked, the tested sample could be placed on the bracket and the angle could be adjusted in two directions to represent a best test location. The tested sample could go upward and downward with a screw rod of the sliding platform. After the scheduled test point becomes available, a cylinder positioned on the power device could throw off the test sample instantly. The test has proven that the L-shaped test path is the best path for falling off. Therefore, the traction or friction would not affect the test and the same striking position or the same block, on which the test sample is falling off, has high reproducibility. Therefore, the utility model has test reference value and could decrease product development time and cost.

Description

Portable type product shatter test machine

Technical field

The utility model relates to a kind of shatter test machine, particularly a kind of shatter test machine that is applicable to the portable type product.

Background technology

Portable type product such as mobile phone or PDA etc., all can be in operation or on the portable when exploitation at the user, situation that ground causes damage is considered because of product is dropped, therefore in design all will be at deficiency reinforcing in this respect, with strengthen the portable type product because of the damage work dropping ground accidentally and cause in response to, so all can utilize shatter test machine simulation test; Existing shatter test machine is to place tester on carriage; as mobile phone; get rid of when utilizing carriage down to break away from and take off tester; it is fallen to obtain the infringement situation that tester lands; analyzed; make things convenient for development and Design with reference to usefulness; but described carriage is generally two macroplate shape bodies and is combined; can only tester be supported by the baseplane; if will make tester be upright or other angle measurement then can be restricted; this moment the dealer can to fetch auxiliary frame usually good with the tester frame; but described auxiliary frame is to be fixed on the carriage; when carriage break away from moment described auxiliary frame and tester can produce friction force; thereby influence actual test status; also get rid of to take off and do not execute external force in addition because carriage is automatic arc; cause tester and carriage when breaking away from, to produce friction force; moreover the track that does not have one section straight line to fall because of tester remakes to get rid of and takes off action; it also is the reason that causes friction force; in addition, existing shatter test machine its same impingement position when tester falls is not high with the repeatability that falls the same area, does not therefore have a reference value; various reasons to sum up; existing shatter test simulation test that machine is done, far from the true time situation, thereby do not have a reference value.

Therefore, how above-mentioned disappearance is forgone, be the place of the technical difficulties of this case inventor institute desire solution.
