Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a smart wearable device. Background Art

[0002] Smart wearable devices are a general term for devices that are designed and developed using wearable technology for daily wear, including smart watches, smart bracelets, smart rings, smart glasses, etc. Smart wearable devices often have functions that traditional wearable devices do not have, such as monitoring of various physiological indicators, display and analysis of sports data, communication, positioning, etc. At present, the commonly used monitoring method for heart rate and blood oxygen monitoring in the dimension of physiological indicator monitoring is photoplethysmograph (PPG).

[0003] The principle of photoplethysmography is to utilize the different refraction effects of blood in blood vessels on light beams under different heart rate conditions, receive the refracted light and analyze it, so as to monitor heart rate and blood oxygen. Therefore, smart wearable devices that can monitor human heart rate and blood oxygen are usually equipped with a transmitting unit for transmitting light beams and a receiving unit for receiving reflected light beams. The processor processes the signal collected by the receiving unit to obtain heart rate information.

[0004] In the above-mentioned prior art, the receiving unit and the collecting unit are usually arranged on the side of the smart wearable device close to the human skin to collect human health information. However, the blood vessel density in the skin of each person wearing the smart wearable device is different, and the signal characteristics that the receiving unit can receive are also different; when the received characteristics are low, the generated human health data is not accurate.

[0006] The present application provides a smart wearable device that adopts the following technical solution:

[0007] A smart wearable device comprises a shell and a display screen arranged on the shell, and a first collection window opened on the shell, wherein the first collection window is arranged on a side of the shell away from the display screen, and a first collection unit is arranged in the first collection window, and at least one second collection window is also opened on the other side of the shell away from the first collection window, and a second collection unit is arranged in the second collection window, and the second collection unit comprises a transmitting unit and a receiving unit, the transmitting unit is used to emit at least one of red light, infrared light or green light, and the receiving unit is used to receive at least one of red light, infrared light or green light.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. On the basis of the existing smart wearable device, a second acquisition unit is added. When the user wears the smart wearable device, the second acquisition unit does not contact the skin of the wearable part. When it is necessary to collect human health data, the second acquisition unit collects signals from the fingers or other parts of the human body with rich blood vessels, combines the first acquisition unit to collect signals from the wearable part, and integrates the two sets of collected signals. The accuracy of the obtained health data is much higher than the health data collected only from the wearable part.

[0019] 2.

[0020] 3. Since the second acquisition unit is arranged away from the wearing part, by setting a flange on the outside of the second acquisition window, setting a limiting groove on the inside, and installing a lens in the limiting groove, the second acquisition unit can be protected and the damage caused by collision when the user moves can be reduced.

In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] A smart wearable device provided in an embodiment of the present application is now described. A smart wearable device provided in an embodiment of the present application is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. The smart wearable device may include but is not limited to a smart watch, a smart bracelet, a smart wristband, smart glasses, a ring or a helmet, etc. For the convenience of explanation, the following uses a smart watch as an example and further describes the present application in detail in conjunction with the accompanying drawings.

[0033] Reference Figure 1 and Figure 2 The smart watch includes a watch body and a watch strap connected to the watch body. The user can wear the watch body on the wrist by buckling the watch strap. The watch body includes a housing 1 and a display screen 2. The display screen 2 is arranged outside the housing 1, so that the user can view the time, heart rate, calories, steps and other sports parameters and health parameters displayed on the display screen 2. A crown is arranged on one side of the housing 1, which is a function button of the smart watch.

[0034] Reference Figure 1 and Figure 2 , a first window is provided on the side of the housing 1 away from the display screen 2 (i.e., the side that fits the skin when the user wears the smart watch correctly), and a first acquisition unit 4 is provided in the first window. The first acquisition unit 4 is provided with multiple transmitting units 61 and at least one receiving unit 62. The transmitting unit 61 can emit at least one of red light, infrared light or green light. The emitted light is reflected by the skin, collected by the receiving unit 62, and converted into an electrical signal, which is finally processed by the processor in the smart watch to obtain the corresponding physiological data. In this application, no specific limitation is made on the number of transmitting units 61 and receiving units 62 in the first acquisition unit 4, and this setting is a conventional setting in this technical field.

[0035] Reference Figure 1 and Figure 2 , since the smart watch of the embodiment of the present application is worn on the user's wrist when worn correctly; and the user's wrist may be sweaty, have skin color, stains, human blood vessel density, etc., resulting in a relatively weak signal collected by the first acquisition unit 4, thereby affecting the accuracy of human health data. Therefore, at least one second acquisition window 5 is provided on the other side of the housing 1 away from the first acquisition window 3, and the second acquisition window 5 is not provided with a second acquisition unit 6. Similar to the first acquisition unit 4, the second acquisition unit 6 is also provided with a transmitting unit 61 and a receiving unit 62, the transmitting unit 61 is used to emit at least one of red light, infrared light or green light, and the receiving unit 62 is used to receive at least one of red light, infrared light or green light.

[0036] Reference Figure 2 and Figure 3 In the embodiment of the present application taking the smart watch as an example, the opening position of the second acquisition window 5 does not contact the skin of the wearing part, that is, the opening position of the second acquisition window 5 can be located on one side of the display screen 2 on the housing 1, or on the side of the housing 1, or on the strap, which can facilitate the second acquisition unit 6 to collect data from human fingers or other parts with rich blood vessels. An implementation method given in the illustrated part of the present application is that the number of the second acquisition window 5 is set to one, and it is set on the side of the housing 1, and is set away from the crown. In addition, the setting of the second acquisition window 5 in the present application is mainly used to collect signals from fingers that are not wearing smart watches, and the design is ergonomic. The thumb with rich blood vessels can easily press on the second acquisition window 5, so as to facilitate the second acquisition unit 6 to collect signals from the finger part, increase the accuracy of signal acquisition, and after the processor comprehensively processes the signals collected by the first acquisition unit 4 and the second acquisition unit 6, the accuracy of the obtained health data can be much higher than the health data collected only from the wrist.

[0037] Reference Figure 4In one embodiment provided in the present application, the emission unit 61 includes a green light emission unit 611, a red light emission unit 612 and an infrared light emission unit 613. The center points of the green light emission unit 611, the red light emission unit 612 and the infrared light emission unit 613 are on the same straight line. The green light emission unit 611, the red light emission unit 612 and the infrared light emission unit 613 are all composed of LED lights that emit corresponding color lights, and the green light emission unit 611, the red light emission unit 612 and the infrared light emission unit 613 can be an integrated design or a plurality of LED lights arranged, and the arrangement order of the green light emission unit 611, the red light emission unit 612 and the infrared light emission unit 613 can be arranged in any order. In this embodiment, the optimal arrangement is that the green light emission unit 611 is between the red light emission unit 612 and the infrared light emission unit 613.

[0038] Reference Figure 4 Further, the center points of the first light sensor 621 and the second light sensor 622 are on the same straight line, and the first light sensor 621 is close to one side of the emitting unit 61. The straight line formed by the center points of the green light emitting unit 611, the red light emitting unit 612, and the infrared light emitting unit 613 is perpendicular to the straight line formed by the center points of the first light sensor 621 and the second light sensor 622, and the first light sensor 621 and the second light sensor 622 are arranged in parallel along the length direction. Therefore, when the second acquisition unit 6 collects signals from the finger, the green light emitting unit 611 emits a green light beam, and the first light sensor 621 and the second light sensor 622 can both receive the light beam reflected from the vascular tissue of the finger, and the light beam is mainly received by the first light sensor 621 close to the emitting unit 61; the red light emitting unit 612 emits a red light beam, and the first light sensor 621 and the second light sensor 622 can both receive the light beam reflected from the vascular tissue of the finger, and the light beam is mainly received by the second light sensor 622 far from the emitting unit 61; the infrared light emitting unit 613 emits an infrared light beam, and the first light sensor 621 and the second light sensor 622 can both receive the light beam reflected from the vascular tissue of the finger, and the light beam is mainly received by the second light sensor 622 far from the emitting unit 61.

[0039] Reference Figure 5 In another embodiment provided by the present application, the transmitting unit 61 includes a green light transmitting unit 611, a red light transmitting unit 612 and an infrared light transmitting unit 613, the receiving unit 62 is provided with a first light sensor 621, the green light transmitting unit 611 is provided on one side of the first light sensor 621, and the red light transmitting unit 612 and the infrared light transmitting unit 613 are provided on the other side of the first light sensor 621 away from the green light transmitting unit 611.

[0040] Reference Figure 5Furthermore, due to the difference in wavelengths of green light, red light, and infrared light, the distance between the green light emitting unit 611 and the first light sensor 621 is smaller than the distance between the red light emitting unit 612 and the infrared light emitting unit 613 and the first light sensor 621, so that the first light sensor 621 can absorb the reflected light to a greater extent, increase the amount of light collected, and thus have a beneficial effect on improving the collection accuracy. When monitoring specific health data (such as heart rate, blood oxygen, etc.), the green light emitting unit 611, the red light emitting unit 612, and the infrared light emitting unit 613 are turned on accordingly, emitting corresponding light beams, and the first light sensor 621 receives the corresponding light beams reflected back from the vascular tissue of the finger.

[0041] Reference Figure 6 In another embodiment provided by the present application, the transmitting unit 61 includes a green light transmitting unit 611, a red light transmitting unit 612 and an infrared light transmitting unit 613, and the receiving unit 62 is provided with a first light sensor 621, the green light transmitting unit 611 is provided on one side of the first light sensor 621, and the red light transmitting unit 612 and the infrared light transmitting unit 613 are provided on the side of the green light transmitting unit 611 away from the first light sensor 621, that is, the transmitting unit 61 is provided on one side of the receiving unit 62. In the embodiment of the present application, the green light transmitting unit 611, the red light transmitting unit 612 and the infrared light transmitting unit 613 are turned on correspondingly, and emit corresponding light beams, and the first light sensor 621 receives the corresponding light beams reflected back from the vascular tissue of the finger part respectively.

[0042] Reference Figure 2 In the present application, the second acquisition unit 6 is arranged on the other side of the housing 1 away from the crown and is not in contact with the skin. It is easy for the LED lamp in the second acquisition unit 6 to be damaged due to collision. Therefore, in order to protect the second acquisition unit 6, a lens 7 is arranged on the second acquisition window 5 facing the outer side of the housing 1. In the present application, the lens 7 is adhesively connected to the housing 1. The lens 7 is arranged in an arc shape, and the side of the lens 7 facing the housing 1 is a concave surface. The side wall of the lens 7 abuts against the side wall of the second acquisition window 5. The second acquisition unit 6 is arranged on the side of the lens 7 facing the housing 1. Further, in order to enhance the protection of the second acquisition window 5 to the second acquisition unit 6, a flange 8 is arranged on the edge of the second acquisition window 5 facing the outer side of the housing 1. When colliding with other objects, the flange 8 can first contact with other objects, which can reduce the probability of the lens 7 directly colliding with other objects, that is, it also has a protective effect. At the same time, the flange 8 is matched with the curvature of the lens 7, which can enhance the strength of the lens 7 and also has a protective effect on the second acquisition unit 6.

[0043] The implementation principle of a smart wearable device in the embodiment of the present application is as follows: the smart watch is worn on the wrist of one arm, and the first acquisition unit 4 acquires the photoelectric signal under the skin of the wrist; the thumb of the other hand is pressed on the second acquisition unit 6, and the second acquisition unit 6 acquires the photoelectric signal on the thumb pad. And through the positional relationship between the green light emitting unit 611, the red light emitting unit 612 and the infrared light emitting unit 613 and the receiving unit 62, the intensity of signal acquisition at two positions of the user is improved, thereby improving the accuracy of the smart watch in collecting human health data.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
