Heart rate module and electronic equipment collecting heart rates

Abstract

The invention discloses a heart rate module and electronic equipment collecting heart rates. The heart rate module includes a substrate, and a first light wave transmitting unit, a second light wave transmitting unit, a first optical sensor chip and a second optical sensor chip which are arranged on the substrate; the substrate is also provided with isolation grating walls for isolating the firstlight wave transmitting unit, the second light wave transmitting unit, the first optical sensor chip and the second optical sensor chip; a first accommodating cavity accommodating the first light wavetransmitting unit, a second accommodating cavity accommodating the second light wave transmitting unit, a third accommodating cavity accommodating the first optical sensor chip and a fourth accommodating cavity accommodating the second optical sensor chip are respectively enclosed by the isolation grating walls and the substrate; the inner walls at the peripheries of the first accommodating cavity and the second accommodating cavity have draft angles; and the surfaces on the inner walls of the first accommodating cavity and the second accommodating cavity are provided with non-conductive reflective plated films. The technical effect of the heart rate module is that the light extraction quantity of the light wave transmitting units can be increased.

Description

technical field [0001] The present invention relates to the field of optical sensors, and more specifically, the present invention relates to a heart rate module and electronic equipment for collecting heart rate. Background technique [0002] Nowadays, based on various factors such as work pressure and unreasonable diet structure, cardiovascular and cerebrovascular diseases such as hypertension and coronary heart disease have gradually become common and frequently-occurring diseases in clinical medicine. Moreover, cardiovascular and cerebrovascular diseases no longer only exist in middle-aged and elderly people, but gradually tend to develop younger, which has attracted widespread attention from all walks of life. In fact, cardiovascular and cerebrovascular diseases are mostly chronic and sudden diseases, which can only be controlled but not cured at present. Patients need to go to the hospital for regular examinations and take related drugs for a long time. However, even ...

Problems solved by technology

[0004] However, as far as the existing technology is concerned, whether the heart rate detection device is a separate solution or an integrated module solution, most of them have the problem of margin loss in terms of the light output intensity of the LED.

Specifically: in the existing heart rate sensor, the light emitted by the LED is scattered to the surroundings, and the light scattered to the obstacle will be absorbed by the obstacle and consumed, which will cause the light incident on the human skin or blood. The light used for detection inside is reduced, which will affect the accuracy of final detection
