[0041] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0042] At present, biometric functions are increasingly being applied to terminal devices. On the one hand, they can increase the functions and usage scenarios of terminal devices, and on the other hand, they can make heart rate detection more convenient, helping users to easily obtain heart rate data.

[0043] Figure 1 A terminal is shown according to the related art, such as Figure 1 As shown, in some solutions, the flash 32 of the mobile phone 30 can be used to emit strong light to illuminate the subcutaneous capillaries of the fingertips, and then the camera module can be used to collect information on blood changes in the blood vessels.

[0044] For example, when the heart pushes fresh blood into the capillaries, the brightness (depth of red) will change slightly, and the camera module 31 can monitor this regularly changing interval. At the same time, by adding an algorithm to the camera module 31, the heart rate information can be obtained and the heartbeat can be calculated.

[0045] When detecting the heart rate, the mobile phone is placed on the camera module 31 and the flash 32, and then the detection is performed. However, this requires placing the finger on the camera module. The finger needs to be placed above the camera. Long-term use will cause the camera to become dirty and worn, affecting the camera effect.

[0046] Figure 2 Another terminal shown according to the related art, such as Figure 2 As shown, in some solutions, a heart rate sensing module can be added to the fingerprint recognition module 33 of the mobile phone 30 to obtain heart rate information. For example, a strong light can be emitted by the light-emitting layer of the display screen to illuminate the subcutaneous capillaries of the fingertips.

[0047] When the heart pushes fresh blood into the capillaries, the color of the blood in the blood vessels changes slightly. The heart rate sensing module obtains information about the changes in blood color, monitors the intervals of this regular change, and then calculates the heartbeat.

[0048] This solution requires the display screen to have an adjustable self-luminous layer, and can only be used for flexible displays, such as OLED (Organic Light-Emitting Diode), but cannot be applied to rigid displays such as LCD (Liquid Crystal Display).

[0049] If this solution is adopted, the test time will be too long, and the strong light emitted by the OLED display will increase the risk of screen burn-in. In addition, the OLED display has multiple functional layers, and multiple opaque functional elements are distributed on the functional layers. These opaque functional elements will block part of the light, resulting in a decrease in the accuracy of the test.

[0050] In view of the above problems, the present disclosure provides a heart rate detection component, which can be used in a terminal to complete the function of detecting heart rate. Figure 3 is a structural diagram of a heart rate detection component according to an exemplary embodiment. Figure 3 As shown, the heart rate detection assembly 10 of the present disclosure includes a light-transmitting cover plate 600, a substrate 100, a first photosensitive chip 301, a packaging layer 500 and a light-emitting device 200. The heart rate detection assembly 10 of the present disclosure can be arranged in a non-display area of ​​a terminal.

[0051] Figure 4 is a schematic cross-sectional structure diagram of a heart rate detection component according to an exemplary embodiment. Figure 5 FIG. 1 is a schematic diagram showing a light path emitted by a heart rate detection component according to an exemplary embodiment. Figure 4 and Figure 5 As shown, the light emitting device 200 is disposed on the first side 101 of the substrate 100, and is used to emit a first light ray 201 to the human body to be tested. The first side 101 is a side of the substrate 100 close to the transparent cover plate 600.

[0052] like Figure 4 and Figure 5 As shown, the first photosensitive chip 301 is disposed on the first side 101 of the substrate 100, and is used to receive a first signal formed by the first light 201 reflected by the human body to be measured. The first signal is used to detect the heart rate of the human body to be measured.

[0053] like Figure 5 As shown, in the present disclosure, the light emitting device 200 emits a first light ray 201, which illuminates the capillary layer of the finger, and the first light ray 201 is transmitted to the inside of the first photosensitive chip 301 through reflection and projection. In the process of the first light ray 201 entering the blood vessel from the fingertip, due to the absorption and attenuation effect of the skin, muscle and blood at the fingertip, when the first light ray 201 reflected by the human body to be tested enters the first photosensitive chip 301, the light intensity detected by the first photosensitive chip 301 will be weakened.

[0054] Since the absorption of light by the skin muscle tissue remains constant throughout the blood circulation, while the blood volume in the skin changes pulsatingly under the action of the heart. For example, when the heart contracts, the peripheral blood volume increases, the light absorption is also the largest, and the light intensity detected by the first photosensitive chip 301 is the smallest. When the heart relaxes, the light intensity detected by the first photosensitive chip 301 is the largest.

[0055] The first photosensitive chip 301 converts the detected light intensity into a first signal and sends it to the signal acquisition and analysis module of the heart rate detection component 10, for example, it can be sent to a receiver. The receiver can convert the light intensity change signal into an electrical signal through comparison and calculation, and the heart rate can be measured.

[0056] The present disclosure can detect the heart rate of a human body by such a design. The heart rate detection component 10 of the present disclosure is arranged in the non-display area of ​​the terminal, so that the terminal can detect the heart rate of a human body without affecting the implementation of other components and functions of the terminal.

[0057] Figure 6 is a schematic diagram showing a structure of a terminal with a heart rate detection component according to an exemplary embodiment. Figure 6 As shown, the heart rate detection component 10 of the present disclosure can be applied to various terminals 20, for example, electronic devices such as mobile phones, tablets or smart wearable devices.

[0058] In the present disclosure, the heart rate detection component 10 is disposed in the non-display area of ​​the terminal 20, for example, Figure 6 As shown, it is arranged on the side of the terminal 20. However, the present disclosure is not limited thereto, and it may also be a non-display area of ​​the display surface of the terminal 20, or it may be arranged on the back of the terminal 20. The specific position may be adaptively adjusted according to the overall design of the terminal 20.

[0059] In the embodiment of the present disclosure, the light emitting device 200 is further used to emit a second light to the human body to be tested. The first photosensitive chip 301 can be used to receive a second signal formed by the second light reflected by the human body to be tested, and the second signal is used to detect the lines of the human body to be tested.

[0060] In the embodiment of the present disclosure, the heart rate detection component 10 can be configured to detect both the heart rate of the human body to be detected and the fingerprint of the human body to be detected. The light emitting device 200 emits a second light, which is reflected or refracted when encountering the fingerprint of the human body.

[0061] In addition, since the fingerprint pattern on the surface of the finger is uneven, the intensity of the reflected or refracted second light is also different. According to these differences, after the second light reflected by the human body to be tested enters the first photosensitive chip 301, the first photosensitive chip 301 converts the light of different intensities into a second signal, and then the fingerprint pattern of the human body to be tested can be obtained.

[0062] Since the light intensity of the first light 201 needs to be sufficient to display the blood vessel color of the fingertip, and the second light only needs to irradiate the surface of the fingertip, the light intensity of the second light can be lower than the light intensity of the first light 201 .

[0063] During use, the light emitting device 200 can emit light of different intensities according to different instructions, which can be the first light 201 or the second light, or light for other purposes. The first photosensitive chip 301 can be an integrated chip with two functions of heart rate detection and fingerprint detection.

[0064] In the embodiment of the present disclosure, the first photosensitive chip 301 integrating the two functions of heart rate detection and fingerprint detection is adopted, which is not only conducive to saving installation space, but also can save costs and manufacturing processes.

[0065] In the embodiment of the present disclosure, two chips can be respectively provided for heart rate detection and fingerprint detection. For example, a first photosensitive chip 301 is provided for heart rate detection, and a second photosensitive chip 302 is further provided on the first side 101 of the substrate 100 for fingerprint detection.

[0066] Figure 7 is a schematic diagram of a light path emitted by a heart rate detection component according to another exemplary embodiment. Figure 7 As shown, in the embodiment of the present disclosure, when the second photosensitive chip 302 is used for fingerprint detection, the light emitting device 200 is also used to emit a third light ray 203 to the human body to be detected. Moreover, the light intensity of the third light ray 203 is lower than the light intensity of the first light ray 201.

[0067] like Figure 3 and Figure 7 As shown, when the second photosensitive chip 302 is used for fingerprint detection, it can be set in the middle position of the first side 101 of the substrate 100. This is conducive to receiving as large an area of ​​light reflected by the fingertips as possible, thereby forming a fingerprint image of as large an area as possible, which can improve the accuracy of fingerprint recognition.

[0068] Furthermore, when the second photosensitive chip 302 is disposed in the middle position of the substrate 100, when the fingertip approaches any position on the surface of the heart rate detection component 10, it can be ensured that a part of the fingertip can always reflect light to the second photosensitive chip 302, thereby improving the sensitivity of the heart rate detection component 10 in recognizing fingerprints.

[0069] In the disclosed embodiment, the second photosensitive chip 302 is used to receive a third image formed by the third light 203 reflected by the human body to be tested. The third image is used to detect the lines of the human body to be tested.

[0070] It should be noted that the light intensity of the third light 203 may be the same as or different from the light intensity of the second light, and may be adaptively set according to the purpose to be achieved.

[0071] In the disclosed embodiment, a module for sensing the distance of a human body to be detected and then activating the fingerprint detection function can also be set. Figure 3 As shown, the heart rate detection component 10 further includes: a distance sensing module 400. The distance sensing module 400 is disposed on the first side 101 of the substrate 100, and is used to sense the distance between the human body to be detected and the heart rate detection component 10. If the distance sensing module 400 senses that the distance between the human body to be detected and the terminal is less than a preset threshold of the terminal, a trigger instruction starts the light emitting device 200 to emit light, for example, to emit one of the first light 201, the second light and the third light 203.

[0072] In the embodiment of the present disclosure, the distance between the human body to be tested and the heart rate detection component 10 can be determined by using the distance sensing module 400. When the distance sensing module 400 determines that the distance between the human body to be tested and the heart rate detection component 10 is less than a certain threshold, it can be set that the human body to be tested starts to use the heart rate detection component 10, and at this time, the light emitting device can be started to emit light to start heart rate detection or fingerprint detection.

[0073] Such a setting can increase the intelligent function of the terminal 20, avoid increasing the user's operation, and optimize the user's experience.

[0074] In the embodiment of the present disclosure, the distance sensing module 400 may be a capacitive sensing device, for example, a receiving end and a transmitting end may be provided on the substrate 100 by copper, for transmitting and receiving signals. The distance sensing module 400 may also be a resistive sensing device, an infrared sensing device, an ultrasonic sensing device, and other touch sensing methods.

[0075] In the embodiment of the present disclosure, taking the capacitive sensing device as an example, the distance sensing module 400 can be arranged in various forms. As shown in FIG, the distance sensing module 400 can adopt a fully enclosed design. Figure 8 is a structural schematic diagram of a heart rate detection component according to another exemplary embodiment. Figure 8 As shown, the distance sensing module 400 can adopt a three-sided surrounding design. Fig. 9 is a structural schematic diagram of a heart rate detection component according to another exemplary embodiment. Fig. 9 As shown, the distance sensing module 400 can adopt a full surround design and a two-side design.

[0076] It should be noted that the distance sensing module 400 of the present disclosure can be arranged in different forms according to different designs. It is sufficient to sense the distance of the human body to be measured within the coverage range of the heart rate detection component 10. For example, the distance sensing module 400 can be arranged on a substrate of some other shapes, and the distance sensing module 400 can be arranged in the form of a circle, a rectangle, a triangle, etc.

[0077] In the disclosed embodiment, the substrate 100, the first photosensitive chip 301, the second photosensitive chip 302 and the distance sensing module 400 are all electrical components, which are easily damaged when exposed on the surface of the substrate. These electrical components can also be packaged. Fig.10 is an exploded diagram of a heart rate detection component according to an exemplary embodiment. Fig.10 As shown, the heart rate detection component 10 may further include a packaging layer 500 , which is disposed between the light-transmitting cover plate 600 and the substrate 100 and is used to connect the light-transmitting cover plate 600 and the substrate 100 .

[0078] In the embodiment of the present disclosure, the light emitting device 200, the first photosensitive chip 301 and the second photosensitive chip 302 are arranged inside the packaging layer 500, which helps to protect these electronic components from damage by external forces.

[0079] In the embodiment of the present disclosure, the light transmittance of the packaging layer 500 is greater than or equal to 90%. Since the heart rate detection component 10 needs to emit light from the light emitting device 200 to the human body to be tested, such a setting can allow sufficient light to pass through the packaging layer 500 to reach the human body to be tested.

[0080] In the embodiment of the present disclosure, the encapsulation layer 500 may be made of a resin material, such as a transparent resin material. After the circuit relationship on the substrate 100 is arranged, the substrate 100, the light-emitting device 200, the first photosensitive chip 301, the second photosensitive chip 302, etc. are encapsulated as a whole using a packaging process using a transparent resin material.

[0081] Fig.11 is a schematic diagram of a packaged structure of a heart rate detection component according to an exemplary embodiment. Fig.11 As shown, the packaged heart rate detection assembly 10 is a whole, which can not only protect the internal electronic components but also facilitate installation.

[0082] In the embodiment of the present disclosure, the encapsulation layer 500 may be in any shape to adapt to being installed in the terminal 20 . Fig.12 is a schematic diagram showing a shape of a packaging layer according to an exemplary embodiment. Fig.12 As shown, the encapsulation layer 500 may be circular, square, rectangular, elliptical, or any other regular or irregular shape.

[0083] In the embodiment of the present disclosure, when the heart rate detection component 10 is installed in the non-display area of ​​the terminal 20, for the sake of aesthetics and to better fit the installation of the terminal 20, the heart rate detection component 10 may further include a cover plate 600. The light-transmitting cover plate 600 is disposed outside the encapsulation layer 500.

[0084] Furthermore, in order to meet the light emission requirements of the light emitting device 200, the light transmittance of the light-transmitting cover plate 600 is set to be greater than or equal to 90%. In some embodiments, glass, such as tempered glass, can be used as the light-transmitting cover plate 600, so that the light-transmitting cover plate 600 has a certain rigidity, which can protect the encapsulation layer 500 and the electronic components inside the encapsulation layer 500.

[0085] In the embodiments of the present disclosure, Figure 4 , Figure 5 and Figure 7 As shown, there is a second side 102 opposite to the first side 101 of the substrate 100, and the second side is the side of the substrate 100 away from the transparent cover 600. The second side 102 is also provided with a soldering pad, through which the heart rate detection component 10 can be soldered to the circuit connected to the power supply of the terminal 20.

[0086] In some embodiments, the circuit can also be connected to the mainboard of the terminal 20, so that the heart rate detection component 10 can be connected to the mainboard of the terminal 20, so as to combine functions such as heart rate detection and fingerprint detection with other functions of the terminal 20.

[0087] By directly connecting the terminal 20 with the mainboard via the soldering pad, the heart rate detection component 10 can be controlled by the control module of the mainboard to complete the functions of the related software. There is no need to set up a separate controller for the heart rate detection component 10, which not only avoids occupying a large space, but also saves components and production processes, thereby improving production efficiency.

[0088] At the same time, such a connection can also combine the heart rate detection and fingerprint detection functions of the heart rate detection component 10 with other functions on the terminal through software settings. For example, the heart rate detection function can be combined with the face recognition function to enhance the biometric recognition function of the terminal.

[0089] In the embodiment of the present disclosure, the heart rate detection component 10 can be installed on the side of the terminal 20, for example, can be installed on the middle frame of the terminal 20. Fig.13 is a schematic structural diagram of a middle frame with a heart rate detection component installed according to an exemplary embodiment. Fig.13 As shown, the heart rate detection assembly 10 further includes a supporting component 700 , and one end of the supporting component 700 is disposed on the second side 102 of the substrate 100 .

[0090] Installing the heart rate detection component 10 on the middle frame 21 is more convenient to operate from the perspective of ergonomics. That is, when the user holds the terminal, he can easily place his finger on the heart rate detection component 10 for detection. Compared with installing it on the display screen of the terminal, installing it on the middle frame can avoid occupying the display screen area.

[0091] It should be noted that the present disclosure is not limited thereto. For some terminals with larger areas, such as tablet computers, which are not convenient for users to hold and operate, the heart rate detection component 10 is arranged on the back of the terminal for easier use.

[0092] Based on the same inventive concept, the present disclosure also provides a terminal 20, including a heart rate detection component 10 as in any of the aforementioned embodiments, and the heart rate detection component is arranged in the non-display area of ​​the terminal. The heart rate detection component 10 can be used to be installed in the terminal 20 to play a role, and there is a process for installing the heart rate detection component 10 in the manufacturing process of the terminal 20. The support component 700 is arranged on the heart rate detection component 10, which is conducive to installing the heart rate detection component 10 in the manufacturing process of the terminal 20.

[0093] In the disclosed embodiment, a groove 27 is provided on the middle frame 21 of the terminal 20, and the other end of the support component 700 is disposed inside the groove 27 to fix the heart rate detection component 10. The terminal 20 includes a limiting component 23, which is disposed inside the groove 27 and is used to fix the support component to the terminal.

[0094] In the embodiment of the present disclosure, the limiting component 23 includes a first end 231 and a second end 232 that are arranged opposite to each other. A pit 701 is arranged on the support component 700, and the first end 231 of the limiting component 23 extends into the pit 701. The support component 700 and the limiting component 23 are snap-fitted together through the pit 701 of the support component 700 and the limiting component 23.

[0095] In the present disclosure, the support component 700 may be made of metal, such as steel or stainless steel. The limiting component 23 may be made of metal, such as copper.

[0096] In the embodiment of the present disclosure, the second end 232 of the limiting component 23 is disposed opposite to the first end 231, and the second end 232 of the limiting component 23 is fixed to the terminal 20, for example, by a fixing component 24. The fixing component 24 may be a screw.

[0097] like Fig.13 As shown, pits 701 may be provided at multiple edges of the support component 700, and a limiting component 23 may be provided at a position corresponding to the pits 701 on the terminal 20. That is, the terminal 20 of the present disclosure may include multiple pits 701 and multiple limiting components 23, and the pits 701 and the limiting components 23 correspond to each other one by one and cooperate with each other.

[0098] In the embodiment of the present disclosure, the heart rate detection component 10 further includes a packaging layer 500, and the packaging layer 500 can be set to fill the opening of the groove 27. When the heart rate detection component 10 is installed on the middle frame 21 of the terminal 20, for the sake of aesthetics and to avoid damaging the strength of the middle frame 21, the packaged heart rate detection component 10 is flush with the outer surface of the middle frame 21, and the packaged heart rate detection component 10 can just fill the opening of the groove 27.

[0099] Such a configuration makes it possible to see no gap from the outside of the terminal 20, which does not affect the appearance of the terminal 20. In addition, by filling the opening of the groove 27 with the heart rate detection component 10, a certain support can be provided to the opening and the slot on the middle frame 21, which is conducive to maintaining the rigidity of the middle frame 21.

[0100] In the embodiment of the present disclosure, the cross-section of the supporting component 700 may also be set to be larger than the cross-section at the opening, so as to further fix the heart rate detection component 10 and the terminal 20.

[0101] Generally, the thickness and size of electronic components such as the substrate 100 are fixed. In order to meet these settings, the size and thickness of the packaging layer 500 and the transparent cover plate 600 can be changed.

[0102] In the embodiment of the present disclosure, the thickness of the substrate 100 may be greater than or equal to 0.1 mm, the thickness of the first photosensitive chip 301 may be less than or equal to 0.2 mm, and the thickness of the light-transmitting cover plate 600 may be greater than or equal to 0.1 mm.

[0103] In the embodiment of the present disclosure, a plurality of components are disposed on the middle frame 21 , and the heart rate detection component 10 may also be configured as other components of the terminal 20 . Fig.14 is a schematic structural diagram of a middle frame with a heart rate detection component installed according to another exemplary embodiment. Fig.14 As shown, the heart rate detection component 10 can be configured as a power button of the terminal 20.

The support component 700 is fixed to the limiting component 23, and the limiting component 23 is elastic. After pressing the support component 700, the limiting component 23 is elastic, so the support component 700 can be restored, and the function of the power button has been completed.

[0105] In the embodiment of the present disclosure, when the heart rate detection component 10 is configured as a power button of the terminal 20, a power switch 26 is provided at the bottom of the groove 27. A conductive component 25 is provided on one side of the support component 700 facing the bottom of the groove 27, and the heart rate detection component 10 contacts the power switch 26 through the conductive component 25.

[0106] Through the above embodiments, the terminal of the present disclosure can add functions such as heart rate detection and fingerprint detection without affecting other functions, and the detection component can be set in the non-display area of ​​the terminal to avoid interference with the display function of the terminal.

[0107] Based on the same inventive concept, the present disclosure also provides a method for detecting heart rate, which is applied to a heart rate detection component as in any of the aforementioned embodiments. Fig.15 is a flowchart of a method for detecting heart rate according to an exemplary embodiment. Fig.15 As shown, the method for detecting heart rate disclosed in the present invention comprises the following steps:

[0108] S11: In response to a first trigger instruction, emitting a first light through a light emitting device;

[0109] S12: receiving, through a first photosensitive chip, a first signal formed by first light reflected by a human body to be tested;

[0110] S13: Based on the first signal, the heart rate of the human body to be measured is detected.

[0111] In an embodiment of the present disclosure, a first trigger instruction is generated in response to a user operation instruction and / or in response to a distance detected by a touch sensing module of a heart rate detection component being less than a threshold value. That is, the first trigger instruction of the present disclosure can be issued by an operation selected by a user on a terminal. In some embodiments, the heart rate detection component can also issue a first trigger instruction when the distance of the human body to be detected by the touch sensing module is less than a preset distance of the terminal.

[0112] In some other possible embodiments, the first trigger instruction may also include two instructions, namely, the first trigger instruction needs to satisfy two signals: a user operation and a touch sensing module detecting that the distance of the human body to be tested is less than a preset distance of the terminal.

[0113] For example, when the user operates, the receiving module of the heart rate detection component receives the first instruction, and when the touch sensing module detects that the distance of the human body to be detected is less than the preset distance of the terminal, the receiving module of the heart rate detection component receives the second instruction. The first instruction can be set on the motherboard of the terminal, and only when the receiving module of the heart rate detection component receives the first instruction and the second instruction, the heart rate detection component can issue the first trigger instruction to control the light-emitting device to emit the first light.

[0114] Fig.16 is a flowchart of a method for detecting heart rate according to another exemplary embodiment. Fig.16 As shown, in the embodiment of the present disclosure, the method for detecting heart rate may further include the following steps:

[0115] S21: in response to a second trigger instruction, emitting a second light through the light emitting device;

[0116] S22: receiving, through the first photosensitive chip, a second signal formed by the second light reflected by the human body to be tested;

[0117] S23: Based on the second signal, the fingerprint of the human body to be tested is identified.

[0118] In the embodiment of the present disclosure, when the first photosensitive chip is an integrated chip having two functions of detecting heart rate and detecting fingerprint, the first photosensitive chip can receive the second signal and identify the fingerprint of the human body to be detected.

[0119] Fig.17 FIG. 1 is a flow chart of a method for detecting heart rate according to another exemplary embodiment. Fig.17As shown, when the heart rate detection component has a second photosensitive chip for detecting fingerprints, the method for detecting heart rate may further include the following steps:

[0120] S31: in response to a third trigger instruction, emitting a third light through the light emitting device;

[0121] S32: receiving, through the second photosensitive chip, a third signal formed by the third light reflected by the human body to be tested;

[0122] S33: Based on the third signal, the fingerprint of the human body to be tested is identified.

[0123] Through the above embodiments, the method for detecting heart rate disclosed in the present invention can obtain the heart rate of the person to be tested and the fingerprint of the person to be tested by identifying the intensity of light reflected by the person to be tested. When applied to a terminal device, the use functions and use scenarios of the terminal device can be increased.
