AI Technical Summary

Technical Problem

In the process of integrating multiple functions and miniaturizing existing electronic devices, the connection strength and stability between the housing and the cover are insufficient, resulting in an inadequate structure that affects the service life and reliability of the device.

Method used

An adhesive layer is provided between the housing and the cover using an adhesive component, including a first adhesive layer and a second adhesive layer, with a base layer disposed between the two, and the thickness of the adhesive layer is increased in the second region to enhance the connection strength, providing a greater thickness that extends along the edge direction of the support component.

Benefits of technology

It improves the connection strength and stability between the housing and the cover, enhances the structural robustness of the electronic device, and extends the service life and reliability of the equipment.
