Description

Impact unit and impact assembly with the impact unit

technical field

The invention relates to an impact unit and an impact assembly using the impact unit; in particular, it relates to an impact unit that acts on an impact platform or an object to be impacted and can be easily disassembled and assembled.

Background technique

With the advent of various electronic products, the corresponding product specifications and industrial standards have become more stringent. Among them, the reliability test on the object itself is an inevitable test process before the electronic product leaves the factory. Reliability testing can not only be used to estimate the service life of electronic products, the transport damage that can be tolerated, etc., but also detect the shortcomings of product structure during the research and development stage. Among them, the most commonly used method for reliability testing is impact testing.

Known impact testing devices used mostly lock the impact unit and the impact platform into a non-detachable aspect, and then fix the object to be tested, such as an electronic product, on the impact platform to perform the relevant impact test process.

As shown in FIG. 1 , a known impact assembly 1 for impact testing includes an impact platform 12 and an impact portion 14 with a specific inclination angle. Wherein, the impact part 14 is fixed under the impact platform 12 by welding or other means, so the impact platform 12 and the impact part 14 are a non-detachable structure. Then, when an object under test 16 is fixed on the impact platform 12 by a belt or a fixed belt, the impact part 14 can generate a reciprocating motion, thereby driving the impact platform 12 to give the object under test 16 an impact force in a specific direction.

The above-mentioned impact test device is widely welcomed and used in the industry because of its low cost advantage. However, since this design is limited to only produce an impact force in a single fixed direction, if the user wants to modify the impact direction or angle , then it is necessary to purchase other impact assemblies in different aspects, which will not only increase the inconvenience in use, but also increase the overall cost of the test procedure.

In view of this, this project provides an impact platform that can be easily assembled and disassembled. According to the direction to be impacted, the impact unit can be adjusted to different angles for testing, so as to achieve customization and reduce testing costs.

To achieve the above purpose, the impact assembly of the present invention includes an impact platform and several impact units. Each of the impact units includes a holding portion, a locking device and an impact portion. The holding part further includes a first inclined surface and a second inclined surface opposite to the first inclined surface. The locking device is arranged on the holding part, which can be a tenon or a structure with functions such as fastening and screwing. In order to fix the impact unit of the present invention to the impact platform. The impact unit is arranged on the supporting part, and the impact part can be an electromagnetic mallet, which provides the impact force of the impact unit in a specific direction through the principle of electromagnetic induction.
