Detailed Description

The terminology used in the description of the embodiments of the application herein is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application.

With the development of electronic device technology, electronic devices have become part of the work and life of users. In order to meet the needs of users for self health management, more electronic devices, such as wearable devices, can support the human body data monitoring function of users. The user can wear wearable equipment, and physiological information such as heart rate, heart rate variability, respiratory rate or blood oxygen is measured to intelligent wrist-watch etc. and then the physical condition of user can be monitored to intelligent wrist-watch etc. based on above-mentioned physiological information.

For easy understanding, related technical terms related to the embodiments of the present application are explained and explained first:

optical vital sign sensor, also known as photoplethysmoscope (PPG): the electronic device can collect physical sign information of the user, such as heart rate, pulse or blood oxygen, through the optical vital sign sensor, so that the user can perform health management according to physiological information. The PPG module includes a Photodiode (PD) and a light emitting diode (light emitting diode, LED), and the LED emits light to the skin of the user. One part of the light is absorbed by the skin of the user and the other part is reflected by the skin of the user. The reflected part of the light is received by the PD, and physiological information of the user, such as heart rate, blood oxygen saturation and blood pressure, can be obtained through analysis and processing of the reflected part of the light.

An electrocardiograph detector, also known as Electrocardiograph (ECG): is a device for measuring the electrical activity of the heart, and the electric potential transmission of the heart can be detected by using electrodes attached to the skin surface of a human body. The result of electrocardiogram is displayed in waveform and mainly comprises P wave, QRS wave group and T wave. The P-wave represents atrial contraction, the QRS complex represents ventricular contraction, and the T-wave represents ventricular diastole. In measurement, it is often necessary to connect electrodes at multiple parts of the body, and a maximum of 10 electrodes can be connected between the chest and the extremities.

The following describes the technical scheme related to the application:

in the related art, the front and back of the smart watch are often configured with a PPG module and an ECG module, so as to detect physiological information of a user.

The PPG module includes: the skin is irradiated by the light emitting diode, the photodiode receives the light signal reflected by the skin, the photodiode converts the light signal into an electric signal, and the electric signal is converted into a digital signal which can be utilized by electronic equipment through analog-to-digital conversion (analogue to digital conversion, A/D), so that the measurement of the human body characteristics by the electronic equipment is realized.

The ECG module usually adopts TCO conductive film to collect the electric signal related to electrocardiogram. The conductive principle of the TCO conductive film is as follows: the intrinsic semiconductor which is weak in conductivity is doped with trace other elements, so that the conductivity of the semiconductor is obviously changed, the trace elements are called impurities, and the doped semiconductor is called an impurity semiconductor. For example, indium Tin Oxide (ITO) transparent conductive glass is obtained by doping tin element into indium oxide, so that conductivity is improved and conductivity is better.

In some embodiments: the physiological information of the user is detected only through the PPG module. It is understood that the PPG-based signal detection method may be applied in a motion scene, or in a stationary scene that is continuously monitored for a long time, such as a sleep monitoring scene.

However, in an athletic scenario, when a user wears the smart watch to run, ride or do other exercises, the skin cannot closely fit the smart watch due to the body movement of the user, for example, the skin may deflect at an angle, and the angle of the PPG signal reflected back through the skin may deviate at an angle due to the shaking of the skin. At this time, since the smart watch only includes one light emitting diode and one photodiode, the photodiode in the PPG module cannot receive an accurate PPG signal, and thus the smart watch cannot obtain effective human body data based on the PPG signal.

In addition, in the sleep monitoring scene, as the PPG module only comprises one light emitting diode and one photodiode, the signal receiving area is smaller, so that the operation power consumption of the PPG module is larger, and the intelligent watch is difficult to ensure long-time signal input, so that the standby time of the intelligent watch can be influenced; moreover, the shorter standby time can lead to the need of charging the smart watch for a plurality of times, and the charging time of the current smart watch is longer, so that the whole available time is shortened.

In some embodiments: the physiological information of the user is detected only by the ECG module. However, since the TCO conductive film is an amphoteric oxide, it is easily corroded when the smart watch is worn on the wrist of a user, and thus the conductive performance is reduced, so that it is not suitable for external use.

In some embodiments: and the PPG module and the ECG module are combined to detect physiological information of a user at the same time, and the PPG module and the ECG module are arranged on the back of the intelligent watch during assembly. However, because the space of the front and back is smaller, accurate detection of the physiological information of the user is difficult to realize in a limited space range, and the detection accuracy is lower.

Based on the above, the embodiment of the application provides a shell component and electronic equipment, which can improve the accuracy of detecting the physiological information of a user by collecting the physiological information of the user under the combined action of an optical vital sign sensor and an electrocardiograph detector; at least part of the electrocardiograph detector is positioned on the attachment wall, so that the electrodes of the electrocardiograph detector are in contact with the skin of a user; the optical vital sign sensor is positioned in the cavity, so that on one hand, the appearance aesthetic property of the electronic equipment can be improved, and on the other hand, the risks of collision and the like between the optical vital sign sensor and the electrocardiograph detector can be avoided; at least part of the attaching wall corresponding to the optical vital sign sensor is a light-transmitting part, so that a light signal emitted by the light-emitting element can conveniently irradiate a measuring part of a measurer through the light-transmitting part, and reflected light formed after the light signal is reflected by the measuring part can be emitted out of the light-transmitting part, so that the light signal is received by the light-receiving element and is used for measuring physiological information such as psychology, respiratory rate, blood oxygen and the like of the measurer; the orthographic projections of the optical vital sign sensor and the electrocardio detector on the surface of the attaching wall are not overlapped, so that on one hand, the optical vital sign sensor and the electrocardio detector can be ensured not to interfere with each other in the detection process, on the other hand, the arrangement mode of the optical vital sign sensor and the electrocardio detector enables the accuracy of the detection effect to be improved to the greatest extent in the limited installation space range of the electronic equipment, on the other hand, the electrocardio detector leaves an optical channel for the optical vital sign sensor, thereby avoiding the problem of light blocking interference between the optical vital sign sensor and the skin of a user.

Referring to fig. 1, an embodiment of the application provides a housing assembly 100 for an electronic device 200. The structure of the electronic device 200 will be described in detail later.

Referring to fig. 2 to 4, the housing assembly 100 includes a housing 110, an optical vital sign sensor 120 and an electrocardiograph detector 130, wherein the housing 110 has an adhesion wall 112 (refer to fig. 5 to 7 in advance) for contacting with the skin of the user, so that the housing assembly 100 can contact with the skin of the user through the adhesion wall 112, thereby detecting physiological information of the user.

In assembly, referring to fig. 5 to 7 in advance, the electrocardiograph detector 130 is disposed on the housing 110, and at least part of the electrocardiograph detector 130 is located on the bonding wall 112, so that the composite electrode 131 of the electrocardiograph detector 130 is beneficial to contact with the skin of the user. The optical vital sign sensor 120 is disposed in the cavity 111 of the housing 110, on the one hand, the cavity 111 of the housing 110 can form protection for the vital sign sensor 120 of the students, on the other hand, the aesthetic property of the appearance of the electronic device 200 can be improved, and meanwhile, the risks of collision or mutual interference and the like caused by the arrangement of the optical vital sign sensor 120 and the electrocardiograph detector 130 outside the housing 110 can be avoided.

It should be noted that, since the optical vital sign sensor 120 is an optical sensor, the optical signal may pass through the attachment wall 112 for convenience. In the embodiment of the present application, at least a portion of the attaching wall 112 corresponding to the optical vital sign sensor 120 is a transparent member, so that the light signal 124 emitted by the light emitting element 121 can be irradiated to the measurement site of the measurer through the transparent member, and the reflected light formed after the light signal 124 is reflected by the measurement site can be emitted out of the transparent member and received by the light receiving element 122.

In order to improve the accuracy of detecting the physiological information of the user in a limited space, in the embodiment of the present application, the orthographic projection of the electrocardiograph detector 130 on the surface of the bonding wall 112 is set to be not overlapped with the orthographic projection of the optical vital sign sensor 120 on the surface of the bonding wall 112.

The arrangement manner can ensure that the two components are not interfered with each other in the detection process, so that the accuracy of the detection effect is improved to the greatest extent in the limited installation space range of the electronic device 200, and the electrocardiograph detector 130 can leave the light channel 123 (shown in fig. 5-7 in advance) for the optical vital sign sensor 120, thereby avoiding the problem of light blocking interference between the optical vital sign sensor 120 and the skin of the user.

The arrangement of the optical vital sign sensor 120 and the electrocardiographic detector 130 will be described in detail below with reference to fig. 5 to 7:

Here, adjacent means that the orthographic projection of the electrocardiograph detector 130 on the surface of the bonding wall 112 and the orthographic projection of the optical vital sign sensor 120 on the surface of the bonding wall 112 may be adjacent, but not overlap. The arrangement mode can ensure that the detection processes of the two are not interfered with each other in a limited installation space, and the accuracy of the detection effect is improved to the greatest extent.

Referring to fig. 6, a second arrangement is as follows: there is a gap between the orthographic projection of the electrocardiograph detector 130 on the surface of the fitting wall 112 and the orthographic projection of the optical vital sign sensor 120 on the surface of the fitting wall 112. The arrangement mode can ensure that the detection processes of the two are not mutually interfered in a limited installation space, thereby improving the accuracy of the detection effect to the greatest extent

In the embodiment of the present application, the specific numerical range of the gap h is not further limited.

In the above arrangement, on the one hand, the electrocardiograph detector 130 may leave the optical channel 123 for the optical vital sign sensor 120, so that the optical signal 124 emitted by the light emitting element 121 can directly irradiate the measurement portion of the user, so as to avoid the problem of light blocking interference between the optical vital sign sensor 120 and the skin of the user; on the other hand, the optical vital sign sensor 120 is close to the side of the center of the attachment wall 112, so that the measurement area of the measurement part irradiated by the optical signal 124 emitted by the optical emitting element 121 is maximized, thereby improving the accuracy of detecting the physiological information of the user, and further being beneficial to health management of the user according to the physiological information.

Note that, the optical channel 123 may be shown with reference to an area enclosed by a dashed box in fig. 5 and 6, and the optical signal 124 is emitted from the light emitting element 121 and reaches the skin of the user via the optical channel 123.

Illustratively, the base member 140 may be a light transmissive glass member.

By including the base member 140, on the one hand, the base member 140 can play a role in fixing the plurality of composite electrodes 131, thereby facilitating enhancement of the assembly stability and the assembly strength between the composite electrodes 131 and the housing 110; on the other hand, the base member 140 is a light-transmitting member, so that the light signal 124 emitted from the light-emitting element 121 can be irradiated to the measurement site of the measurer through the base member 140, and the reflected light formed after the light signal 124 is reflected by the measurement site can be emitted out of the base member 140, so as to be received by the light-receiving element 122.

fig. 12 is a schematic diagram of a first structure of an optical vital sign sensor according to an embodiment of the present application, and fig. 13 is a schematic diagram of a second structure of an optical vital sign sensor according to an embodiment of the present application.

Referring to fig. 12, the optical vital sign sensor 120 includes a light emitting element 121 (LED) and a light receiving element 122 (PD), the light emitting element 121 is configured to emit a light signal 124 toward a measurement site of the skin of a user, the light receiving element 122 is configured to receive reflected light formed by the light signal 124 after being reflected by the measurement site, and the light receiving element 122 is further configured to convert the received reflected light into a detection electrical signal, so that measurement of physiological information such as heart rate, respiration rate, blood oxygen, and the like of the user is achieved through the optical vital sign sensor 120.

In the embodiment of the application, the PPG module including a plurality of light emitting elements 121 and a plurality of light receiving elements 122 is mainly described as an example.

For example, the light emitting element 121 may include two, three, four, or more, and the light receiving element 122 may include two, three, four, or more. In the embodiment of the present application, two light emitting elements 121 and eight light receiving elements 122 are mainly described as examples.

Eight light receiving elements 122 form an enclosure around the outside of the two light emitting elements 121. In this way, the electronic device 200 can receive the optical signal 124 to the maximum extent by using the surrounding structure formed by the eight light receiving elements 122, so that effective physiological information can be ensured to be obtained in the sports scene.

In addition, compared with the arrangement of one photodiode, the eight light receiving elements 122 can significantly increase the light receiving area, thereby reducing the power consumption of the PPG module and enhancing the cruising ability of the electronic device 200.

It will be appreciated that the number of light emitting elements 121 and light receiving elements 122 in the above-described structure is merely an example, and when the number of light receiving elements 122 is larger, the smaller the included angle formed between each adjacent light receiving elements 122, the more the surrounding structure formed by the plurality of light receiving elements 122 approximates a circle, and thus more light signals 124 can be received.

With continued reference to fig. 13, the light emitting element 121 may include: the LEDs 1 and 2, the LEDs 1 and 2 may emit red light, green light, infrared light, etc., respectively, and the eight light receiving elements 122 in a surrounding structure may include: PD1, PD2, PD3, PD4, PD5, PD6, PD7, and PD8, two LEDs and eight PDs may constitute a plurality of different optical channels 123 over the distance from LED to PD.

It will be appreciated that since the distances of the respective optical channels 123 are not equal, they may be further divided into short-distance optical channels (e.g., L2), medium-distance optical channels (e.g., L1, L3, L4, and L8), and long-distance optical channels (e.g., L5, L6, and L7) according to the size of the distances.

So configured, the plurality of optical channels 123 may provide different signal strengths for different application scenarios. For example, when the PPG module in the electronic device 200 is used to monitor blood oxygen, the optical signals 124 on the middle-distance optical path and the long-distance optical path may be selected as input signals for monitoring blood oxygen; alternatively, when using the PPG module in the electronic device 200 to monitor heart rate, the optical signals 124 on the mid-distance and near-distance optical paths may be selected as input signals to monitor heart rate. Therefore, only by obtaining the signal intensities under the optical channels 123 corresponding to the scene, the calculation of the signal intensities received under all the optical channels 123 can be avoided, and the calculation overhead of the electronic device 200 can be saved.
