Description

Technical Field

[0001] This utility model relates to the field of aging test technology, and in particular to a rapid aging test device for electronic products. Background Technology

[0002] With the continuous development of electronic technology, product lifespan has become a crucial indicator for both consumers and manufacturers. To ensure the stability of electronic products under various operating environments, rapid aging test equipment has emerged. This type of equipment accelerates the aging process of electronic products by simulating extreme environmental conditions, helping manufacturers identify potential failure modes. This method can quickly detect reliability issues that may arise during long-term use, such as thermal failure, material aging, and connector loosening. With continuous technological advancements, rapid aging test equipment has made significant progress in accuracy and intelligent analysis. Nevertheless, the complexity of electronic products and the realistic simulation of test conditions remain challenges in this field. Overall, rapid aging test equipment provides crucial support for improving product quality and reliability and will become increasingly intelligent and multifunctional in the future, helping manufacturers identify and resolve quality issues in a shorter time.

[0003] A search revealed an existing patent (publication number: CN219590434U) that discloses an aging test device for electronic products. The device includes an aging machine body and a working plate. Electric sliders are symmetrically installed on the upper surface of the aging machine body. A working plate is mounted on the upper surface of the electric sliders via a connector. Connecting frames are symmetrically installed on the upper surface of the working plate. An L-shaped plate is arranged on the inner side of the connecting frame. A placement groove is formed on the inner side of the L-shaped plate. A fixing spring is installed at the top of the placement groove. A fixing slider is installed at the other end of the fixing spring. A clamping plate is installed on the inner side of the fixing slider. This invention employs a heating fan structure to raise the temperature inside the aging machine body, thereby testing the performance of electronic products at high temperatures and achieving the purpose of testing their aging degree. Simultaneously, a cooling fan structure is used to blow out cold air, rapidly cooling the electronic products while testing their resistance to temperature differences.

[0004] However, in actual use, while the above-mentioned methods detect the aging rate of electronic products through hot and cold air testing, they cannot effectively detect the vibration aging process. This brings several disadvantages to rapid aging testing equipment. First, it cannot assess the stability of products in vibration environments, especially components such as connectors, circuit boards, and sensors that are easily affected by vibration. Second, hot and cold air testing cannot fully simulate the multiple environmental pressures in actual use, underestimating the fatigue effects of long-term use, such as component loosening and poor contact. Furthermore, this method leads to incomplete test results, overlooking potential faults caused by vibration, increasing quality control risks, and potentially affecting product design and optimization decisions.

[0005] Therefore, this utility model provides a rapid aging test device for electronic products. Utility Model Content
