Light-leakage-proof structure and intelligent watch with light-leakage-proof structure

Abstract

The invention provides a light-leakage-proof structure. The light-leakage-proof structure comprises a bottom shell, and a heart rate measuring hole and a fixed ring which are located at the center ofthe bottom shell, and further comprises a fixed supporting sheet which is arranged on the heart rate measuring hole and can rotate relatively, wherein the fixed supporting sheet comprises an arc-shaped substrate and a rotary shaft; two ends of the arc-shaped substrate are raised in a direction opposite to the bottom shell; a through hole is formed in the arc-shaped substrate; connection blocks arearranged at two sides of the through hole; connection holes are formed in the connection blocks; the rotary shaft is arranged in the connection holes and is pivoted to the bottom shell. According tothe light-leakage-proof structure and an intelligent watch, provided by the invention, the fixed supporting sheet is arranged at the bottom of a shell body of the watch; the arc-shaped substrate on the fixed supporting sheet rotates relatively on the bottom shell through the rotary shaft; when a user wears the intelligent watch, relative fixed supporting of a space around the heart rate measuringhole is ensured all the time, so that a light leakage condition is prevented from occurring, and furthermore, the accuracy of measuring the heart rate by utilizing a heart rate measuring device in thewatch can be effectively improved.

Description

technical field [0001] The invention relates to the field of watches, in particular to an anti-light leakage structure and a smart watch with the anti-light leakage structure. Background technique [0002] The heart rate monitors currently on the market are generally photoelectric sensors. The measurement principle of the photoelectric induction watch is to measure the heart rate through the photoelectric transmission in the watch. The photoelectric measurement method is mainly to measure the pulse by using the change of the light transmittance caused by the change of the density of the blood in the blood vessel of the arm when it pulsates. The photoelectric sensor heart rate watch will be equipped with a luminous LED light and a photosensitive sensor at the bottom of the watch case. The light wave of the green wavelength is emitted by the luminous LED light. The photosensitive sensor receives the reflected light from the arm skin and senses the change of the light field in...
