Description

Technical Field

[0001] This utility model relates to the technical field of smartwatches, and in particular to a camera motion mechanism for smartwatches. Background Technology

[0002] As a wearable device, smartwatches are favored by a wide range of consumers because they have core functions such as location tracking and anti-loss, audio and video calls, as well as multiple functions such as electronic payment, health monitoring, social chat, photography, and intelligent object recognition.

[0003] Traditional smartwatches, with their pop-up or mechanical cameras, require bulky transmission components, increasing their thickness and contradicting the current trend towards thinner and lighter designs. This increased thickness reduces the fit of the smartwatch to the wrist, potentially causing pressure marks with prolonged wear, especially noticeable on women or users with smaller wrists. Furthermore, it's worth noting that when the smartwatch's thickness exceeds a certain level, it can lead to uneven pressure distribution on the wrist, potentially hindering blood circulation with extended wear.
