Description

Technical Field

[0001] The utility model belongs to the technical field of heart rate detection, in particular to a heart rate detection device. Background Art

[0002] Heart rate refers to the number of heartbeats per minute in a normal person's quiet state, also known as resting heart rate, which is generally 60 to 100 beats per minute. It may vary from person to person due to age, gender or other physiological factors. Changes in heart rate are closely related to heart disease. If the heart rate exceeds 160 beats per minute, or is lower than 40 beats per minute, it is mostly seen in patients with heart disease. There are many heart rate detection devices on the market, such as various heart rate detection bracelets and heart rate detection watches, which are equipped with optical heart rate sensors. Optical heart rate sensors can quickly detect changes in blood oxygen in subcutaneous capillaries through optical technology to detect the corresponding human heart rate. However, current heart rate detection devices still have the following disadvantages in actual use:

[0003] 1. Since the optical heart rate sensor detects the fluctuation of wrist blood flow by sending light and receiving reflected light, and obtains the heart rate value through an algorithm, when the heart rate detection device worn on the user's wrist is too loose, there is a large gap between the skin on the wrist and the optical heart rate sensor on the device. The external light in the gap will interfere with the normal operation of the optical heart rate sensor, causing the error of the optical heart rate sensor to increase during detection, resulting in a large error in the result detected by the heart rate detection device;

[0004] 2. The current heart rate monitoring equipment is generally worn on the monitor's watch strap. However, for some older users, especially those with difficulty in hand movement, it is difficult and inconvenient for them to tie the strap of the heart rate monitoring equipment to their wrist.

[0005] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Utility Model Content

[0006] The utility model aims to provide a heart rate detection device, which, through the action of two left and right bending springs, pulls two rubber connecting posts to slide toward the inner lower ends of two connecting sleeves respectively, so that the two rubber connecting posts drive the heart rate detection device body to fit closely to the wrist skin of a user, thereby reducing the gap between the heart rate detection device body and the wrist skin of the user, and solving the problem that the existing heart rate detection device is too loose when worn, and there is a large gap between the skin at the wrist and the optical heart rate sensor on the device, which increases the error of the optical heart rate sensor during detection.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model discloses a heart rate detection device, comprising a heart rate detection device body, wherein rubber connecting columns are symmetrically fixedly installed on the left and right sides of the outer wall of the heart rate detection device body, connecting sleeves are slidably connected to the lower sides of the side walls of the two rubber connecting columns, bending springs are symmetrically fixedly installed on the lower ends of the outer walls of the two rubber connecting columns, the bending springs on the left and right sides are respectively fixedly connected to the lower ends of the inner walls of the connecting sleeves on the corresponding sides, a rotating connecting block is fixedly installed on the lower end of the outer wall of the connecting sleeve on the left side, a connecting shaft is fixedly installed on the front and rear ends of the inner wall of the rotating connecting block, the outer wall of the connecting shaft is rotatably connected to a rotating sleeve, and an arc-shaped rubber rotating plate is fixedly installed on the side wall of the rotating sleeve.

[0009] The utility model has the following beneficial effects:

[0010] 1. The utility model uses the action of two left and right bending springs to pull the two rubber connecting columns to slide toward the inner lower ends of the two connecting sleeves respectively, so that the two rubber connecting columns drive the heart rate detection device body to fit closely to the wrist skin of the user, reduce the gap between the heart rate detection device body and the wrist skin of the user, reduce the interference of external light in the gap on the heart rate detection sensor, and improve the accuracy of the device during detection.

[0011] 2. When the utility model is in use, the arc-shaped rubber rotating plate and the connecting sleeve can be quickly closed through the magnetic connection between the magnetic block 2 and the magnetic block 1. At the same time, the torsion spring can enable the arc-shaped rubber rotating plate to have an elastic force for automatic closing when it is opened, so that users with inflexible hands can close the arc-shaped rubber rotating plate conveniently, and older users with inconvenient hand movements can wear and use the device, thereby improving the convenience of the device.
