Description

Technical Field

[0001] The utility model relates to the technical field of intelligent devices, in particular to a bottom shell of an intelligent watch. Background Art

[0002] Current smart watches use infrared and other devices to emit light through the corresponding light-transmitting structure at the bottom shell to contact the human skin or even pass through the human skin to obtain parameters such as blood oxygen and heart rate. Therefore, the specific structure of the bottom shell affects its specific performance.

[0003] In the prior art, although the bottom shell needs to be light-transmissive, it is usually also necessary to ensure the sealing of the bottom shell, that is, the inside and outside of the smart watch need to be isolated to prevent external dust from entering the bottom shell and affecting the specific performance of the electronic components. However, in the prior art, isolation is usually achieved by simply sticking a layer of film, resulting in poor isolation effect, which affects the specific performance of the smart watch. Summary of the invention
