Description

Technical Field

[0001] This utility model relates to the field of wearable device technology, and further to a host structure and a smartwatch. Background Technology

[0002] With the development of mobile technology, many traditional electronic products have begun to add mobile functions. For example, watches that used to be used only to tell time can now be connected to the Internet through smartphones or home networks to display incoming call information, communications, news, weather information, and other content. Such new watches can be called smartwatches.

[0003] Smartwatches face significant challenges in terms of functional integration and miniaturization. Existing smartwatches generally suffer from unreasonable internal stacking structures. Specifically, the internal stacking method is often a planar layered layout, with functional modules (such as NFC, battery, circuit board, etc.) stacked sequentially, resulting in space utilization of only 65%–75%, and a device thickness often exceeding 10mm. The chaotic layout of functional modules (such as NFC, communication module, sensors, battery, etc.) is prone to electromagnetic interference or poor heat dissipation. Replacing the SIM card usually requires removing the back cover, which is cumbersome and compromises sealing.

[0004] Therefore, it is necessary to design a host architecture and a smartwatch to solve the above problems. Utility Model Content

This allows the watch to have practical functions such as an altimeter and weather forecast, significantly improving the product's environmental awareness. The bending angle is between 30° and 150°, and the bending height is between 0.5mm and 3mm. This bending structure, by changing the local spatial orientation of the circuit board, allows the pneumatic assembly 9 to fit snugly against the internal contour of the housing, reducing the component stacking thickness and improving the space utilization of the cavity.

[0055] Furthermore, a heat-insulating shielding layer is provided between the circuit board 4 and the battery 5 to block electromagnetic interference and heat transfer. A portion of the circuit board 4 is bent towards the end of the housing 1 to form a data interface connection part 46.
