Smartwatch Structural Design
Overall Solution Considerations:
Due to the small size of the watch and the need for easy assembly, it is best to first assemble the PCBA together and then insert the PCBA as a whole into the front shell, which requires a bracket. According to this functional configuration, the antenna is only Bluetooth, which is manageable, requiring only a small antenna area. The antenna can be placed on the bottom shell, making contact through a spring contact. When worn on the wrist, there are usually waterproof requirements, which need to be considered.
According to the appearance diagram, the TP should be installed on the outside. Therefore, the assembly sequence should be to install the PCBA first, then the TP, followed by the TP’s FPC, then the battery, and finally the back cover.
Materials: According to the process diagram,
Assembly Method: TP glued to the front shell, PCBA and front shell locked with screws, snap hooks, side buttons with waterproof requirements can use watch accessories to snap onto the front shell. The bottom shell is installed last, locked with screws, snap hooks, and waterproof pads.
