Problems solved by technology

[0004] However, when there is sweat on the surface of the charging contact, the action of the current will accelerate the corrosion rate during the charging process.
At the same time, the existing technology cannot simulate the electrochemical corrosion of the charging contacts in the entire life cycle of the product, and cannot meet the needs of artificial sweat testing on the charging contacts of wearable products

Abstract

Disclosed are a charging contact testing method and testing device for a wearable device. By calculating the corresponding test time according to the predetermined test temperature, and then at the predetermined test temperature, after the test time is continuously applied to the charging contact to be tested in the artificial sweat, the charging contact to be tested is detected. performance. As a result, the sweat corrosion resistance performance of the charging contacts of the wearable device can be tested throughout the life cycle, improving the reliability of the test.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a charging contact test method and test device of a wearable device. Background technique [0002] For wearable devices such as smart watches and smart bracelets, sweat, sweat and other body secretions will adhere to the surface of the charging electric shock after being worn by the human body. These secretions will corrode the charging coating due to the presence of sodium chloride and other ingredients. [0003] The artificial sweat test uses the method of simulating artificial sweat to test the metal or electroplating products that are often worn and used by people in direct contact with the skin to test whether they can withstand the long-term corrosion of sweat. In the prior art, the test sample is usually smeared with sweat and placed in a high-temperature and high-humidity environment; alternatively, the test sample is directly put into an artificial sweat tes...
