[0002] The present application relates to the field of data detection technology, and in particular to a detection device, an electronic device and a control method thereof. Background Art

[0003] As living standards continue to improve, users are demanding more advanced features from their electronic devices. Devices integrated with health sign monitoring capabilities can provide timely monitoring of users' health data, such as heart rate, blood oxygen levels, electrocardiogram (ECG), and blood pressure, enabling users to stay informed about their physical condition and prevent illness. However, current devices with these health sign monitoring capabilities are relatively large, hindering the trend toward miniaturization and portability.

[0004] Summary of the Invention

[0005] The present application provides a detection device, an electronic device and a control method thereof, which are used to solve the problem that devices with health sign detection functions are large in size.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In one aspect of the present application, a detection device is provided, which includes a first circuit board, a light-emitting device, a photoelectric converter, a metal cover plate and a light-transmitting structure. The light-emitting device is arranged on the first circuit board, and the light-emitting device is electrically connected to the first circuit board. The photoelectric converter and the light-emitting device are arranged on the same side of the first circuit board, and the photoelectric converter is electrically connected to the first circuit board. In addition, the metal cover plate is arranged on the first circuit board, and the metal cover plate is electrically connected to the first circuit board. A accommodating cavity is formed between the metal cover plate and the first circuit board, and the light-emitting device and the photoelectric converter are arranged in the accommodating cavity. A first light hole and a second light hole are provided on the metal cover plate, which pass through the metal cover plate. The first light hole exposes the light-emitting surface of the light-emitting device, and the second light hole exposes the light-receiving surface of the photoelectric converter. The light-transmitting structure is filled in the first light hole, the second light hole and the accommodating cavity. The light-transmitting structure wraps the light-emitting device and the photoelectric converter, and is connected to the light-emitting device, the photoelectric converter, the first circuit board and the metal cover plate to form an integrated structural component.

[0008] In summary, in the detection device provided by the embodiment of the present application, the light-emitting device and the photoelectric converter are housed within the metal cover plate, and the light-transmitting structure can cover the light-emitting surface of the light-emitting device and the light-receiving surface of the photoelectric converter, thereby ensuring the normal operation of the light-emitting device and the photoelectric converter. In addition, the light-transmitting structure can also cover the side surfaces of the light-emitting device and the photoelectric converter. Therefore, the light-transmitting structure can cover the surfaces of the light-emitting device and the photoelectric converter except for the surfaces facing the first circuit board, so that the light-transmitting structure can wrap the light-emitting device and the photoelectric converter, and further enable the light-transmitting structure to be connected to the light-emitting device, the photoelectric converter, the first circuit board, and the metal cover plate to form an integral structural member. Based on this, the detection device provided by the embodiment of the present application can connect the metal cover plate serving as the ECG electrode to the light-emitting device and the photoelectric converter through the light-transmitting structure embedded in the metal cover plate. Therefore, the detection device does not need to be provided with a bracket for housing the light-emitting device and the photoelectric converter, and the adhesive layer and transparent plate stacked on the bracket. In this way, the detection device does not need to consider the size requirements of the adhesive layer and the transparent plate in terms of length, width, and height, so the size of the detection device can be reduced, thereby achieving the purpose of miniaturization design of the detection device. In this case, when the detection device with the above-mentioned miniaturized design is applied to electronic equipment, it is beneficial to reduce the size of the electronic equipment, thereby alleviating the problem of the large size of the device with the health sign detection function.

[0009] In an optional embodiment, the detection device includes a first pressure rod, a deformable plate, and a pressure-sensitive element. The first pressure rod is disposed on a side of the first circuit board facing away from the metal cover, with the first end of the first pressure rod abutting or connecting to the first circuit board. The deformable plate is disposed on the side of the first pressure rod facing away from the first circuit board, and has a first cantilever end and a fixed end. The first cantilever end abuts or connects to the second end of the first pressure rod, and the fixed end is used to secure the deformable plate. The pressure-sensitive element covers at least a portion of the first cantilever end and is electrically connected to the first circuit board. In this way, when a user's finger presses downward on the metal cover, the external force applied by the user can be transmitted through the metal cover to the first circuit board, and then through the first circuit board to the first pressure rod located below the first circuit board. Because the first pressure rod abuts or connects to the first cantilever end of the deformable plate, the fixed end of the deformable plate secures the deformable plate to a component, such as the middle frame, so that the first cantilever end of the deformable plate can deform downward under the pressure of the first pressure rod. In addition, since the pressure sensitive element covers at least a portion of the first cantilever end, the pressure sensitive element can utilize the piezoelectric induction principle to convert the deformation of the first cantilever end into an electrical signal and transmit it to the first circuit board electrically connected to the pressure sensitive element to detect the user's pressing force.

[0010] In an optional embodiment, the pressure-sensitive element is disposed on the side of the deformable sheet facing the metal cover, and the detection device further includes a mounting post located on the side of the deformable sheet facing away from the metal cover. The first end of the mounting post is connected to the fixed end, and the second end of the mounting post is used to secure the detection device. For example, the entire detection device can be secured to the middle frame via the second end of the mounting post. In this manner, since the pressure-sensitive element is disposed on the side of the deformable sheet facing the metal cover, the position of the mounting post is not affected. Furthermore, since the first end of the mounting post is connected to the fixed end of the deformable sheet, the fixed end of the deformable sheet is secured thereto.

[0011] In an optional embodiment, the pressure-sensitive element includes a resistance strain gauge, and the portion of the resistance strain gauge covering the first cantilever end has a first resistor and a second resistor. The detection device also includes a third resistor and a fourth resistor. The first resistor and the second resistor are connected in series to form a first circuit; the third resistor and the fourth resistor are connected in series to form a second circuit, the first circuit and the second circuit are connected in parallel to form a first full-bridge circuit, and the first full-bridge circuit is electrically connected to the first circuit board. In this way, when the user presses the metal cover of the detection device, the first cantilever end of the deformation plate will be deformed. In this case, the resistance values ​​of the first resistor and the second resistor in the pressure-sensitive element covering the first cantilever end will change, thereby changing the voltage output by the first full-bridge circuit, which matches the pressure of the user pressing the metal cover, so that the purpose of detecting the user's pressing pressure, such as the first pressure value, can be achieved by obtaining the above-mentioned voltage difference.

[0012] In an optional embodiment, the deformable sheet further has a second cantilever end, and the fixed end is located between the first cantilever end and the second cantilever end. The pressure-sensitive element covers at least a portion of the second cantilever end. The detection device also includes a second pressure rod, which is arranged on the side of the first circuit board facing away from the metal cover plate, the first end of the second pressure rod abuts or is connected to the first circuit board, and the second end of the second pressure rod abuts or is connected to the second cantilever end. In this way, when the user's finger presses the metal cover plate downward, the external force applied by the user can be transmitted to the first circuit board through the metal cover plate, and then transmitted to the first pressure rod and the second pressure rod located below the first circuit board through the first circuit board. Since the first pressure rod and the second pressure rod abut or are connected to the first cantilever end and the second cantilever end of the deformable sheet respectively, the fixed end of the deformable sheet located between the first cantilever end and the second cantilever end fixes the deformable sheet to a component, such as a middle frame, so that under the pressing action of the first pressure rod and the second pressure rod, the first cantilever end and the second cantilever end of the deformable sheet can be deformed downward. In addition, since the pressure-sensitive element covers at least a portion of the first cantilever end and at least a portion of the second cantilever end, the pressure-sensitive element can utilize the piezoelectric induction principle to convert the deformation of the first cantilever end and the second cantilever end into an electrical signal, and transmit it to the first circuit board electrically connected to the pressure-sensitive element to detect the user's pressing force. As can be seen from the above, when the user presses the metal cover of the detection device, the processor of the electronic device can compare the deformation of the first cantilever from the deformation sheet and the deformation of the second cantilever end, and then determine whether the user's pressing position is in the middle position of the metal cover, so as to improve the detection accuracy. Therefore, the above-mentioned detection device can be called a dual-channel detection structure.

[0013] In an optional embodiment, the deformable sheet further has a second cantilever end, which is located on the side of the first cantilever end away from the fixed end, and there is a gap between the first cantilever end and the second cantilever end. The pressure-sensitive element covers at least a portion of the second cantilever end. The second end of the first pressure rod is also in contact with or connected to the second cantilever end. In this way, by providing a pressure rod, that is, the first pressure rod can press the first cantilever end and the second cantilever end at the same time, thereby driving the first cantilever end and the second cantilever end to deform at the same time, thereby achieving the purpose of dual-channel pressure detection.

[0014] In an optional embodiment, the pressure-sensitive element includes a resistance strain gauge. The portion of the resistance strain gauge covering the second cantilever end has a fifth resistor and a sixth resistor. The fifth resistor and the sixth resistor are connected in series to form a third circuit, the second circuit and the third circuit are connected in parallel to form a second full-bridge circuit, and the second full-bridge circuit is electrically connected to the first circuit board. In this way, when the user presses the metal cover of the detection device, the second cantilever end of the deformation plate will be deformed. In this case, the resistance values ​​of the fifth resistor and the sixth resistor in the pressure-sensitive element covering the second cantilever end will change, thereby changing the voltage output by the second full-bridge circuit, which matches the pressure of the user pressing the metal cover, so that the purpose of detecting the user's pressing pressure, such as the second pressure value, can be achieved by obtaining the above-mentioned voltage difference. As can be seen from the above, when a user presses the metal cover of the detection device, the user's pressing pressure detected by the first full-bridge circuit, for example, the first pressure value comes from the deformation of the first cantilever end of the deformable piece, and the user's pressing pressure detected by the second full-bridge circuit, for example, the second pressure value comes from the deformation of the second cantilever end of the deformable piece. The above-mentioned first cantilever end and the second cantilever end are respectively located on either side of the fixed end. Therefore, the processor of the electronic device can determine whether the user's pressing position is in the middle of the metal cover by comparing the difference between the above-mentioned first pressure value and the second pressure value, thereby improving detection accuracy. Therefore, the above-mentioned detection device can be called a dual-channel detection structure.

[0015] In an optional embodiment, the first circuit board includes a flexible circuit board and a support plate. The support plate is arranged on the side of the flexible circuit board facing away from the metal cover plate, and the support plate is connected to or abuts the first pressure bar. The rigidity of the support plate is greater than that of the flexible circuit board, thereby enabling support. In addition, when the user presses the metal cover plate, the force transmitted to the first circuit board can be transmitted to the first pressure bar via the support plate. Alternatively, the first circuit board includes a printed circuit board. When the user presses the metal cover plate, the force transmitted to the first circuit board can be transmitted to the first pressure bar.

[0016] In an optional embodiment, the detection device further includes a first metal electrode sheet, which is arranged on the side of the support plate facing away from the metal cover plate, and the first metal electrode sheet is electrically connected to the flexible circuit board. The pressure-sensitive element is located between the deformable sheet and the metal support plate, and the pressure-sensitive element includes a second metal electrode sheet, and a capacitor is formed between the second metal electrode sheet and the first metal electrode sheet. In this way, when the user presses the metal cover plate of the detection device, the distance between the two metal electrodes changes, thereby changing the capacitance value of the capacitor, and the capacitance value matches the user's pressing pressure, thereby achieving the purpose of detecting the user's pressing pressure.

[0017] In one optional embodiment, the support plate comprises a metal material. A pressure-sensitive element is located between the deformable sheet and the support plate, and the pressure-sensitive element comprises a metal coil. In this case, a current can be passed through the coil. When a user presses the metal cover of the detection device, the distance between the support plate and the pressure-sensitive element changes, thereby changing the magnetic field generated by the coil and causing the impedance of the coil to change. This impedance can then match the user's pressure, thereby detecting the user's pressing force.

[0018] In an optional embodiment, the detection device further includes conductive silicone, which is disposed between the metal cover and the first circuit board, with a first end of the conductive silicone electrically connected to the metal cover, and a second end of the conductive silicone electrically connected to the first circuit board. In this case, the ends of the conductive silicone can be welded to pads on the metal cover and the first circuit board, respectively, through a welding process. Thus, the metal cover and the first circuit board can be electrically connected via the conductive silicone, thereby achieving signal interconnection between the conductive silicone and the first circuit board.

[0019] In an optional embodiment, the detection device further includes conductive adhesive, which is disposed between the metal cover and the first circuit board, adheres to the metal cover and the copper-leaking portion of the first circuit board, and is electrically connected to the metal cover and the first circuit board. In this case, the portion of the first circuit board electrically connected to the conductive adhesive does not require a solder pad. Instead, the conductive adhesive is adhered to the copper-leaking portion of the first circuit board, and the side of the conductive adhesive facing away from the copper-leaking portion is adhered to the metal cover, thereby enabling signal interconnection between the metal cover and the first circuit board via the conductive adhesive.

[0020] In an optional embodiment, the detection device also includes a metal shrapnel, which is arranged in the accommodating cavity. The first end of the metal shrapnel is welded to the metal cover plate, and the second end of the metal shrapnel abuts the copper leakage part of the first circuit board. In the process of the second end of the metal shrapnel abutting the copper leakage part of the first circuit board, the metal shrapnel can be elastically deformed, and the deformed metal shrapnel can be in closer contact with the copper leakage part of the first circuit board. Alternatively, the second end of the metal shrapnel is welded to the first circuit board, and the first end of the metal shrapnel abuts the metal cover plate. Similarly, in the process of the first end of the metal shrapnel abutting the metal cover plate, the metal shrapnel can be elastically deformed, and the deformed metal shrapnel can be in closer contact with the metal cover plate. In this way, the metal cover plate can achieve signal interconnection with the first circuit board through the metal shrapnel.

[0021] In an optional embodiment, the metal cover plate includes a metal cover plate body and a light-shielding wall. The metal cover plate body is covered on the first circuit board, and the metal cover plate body is electrically connected to the first circuit board. The metal cover plate body is provided with a first light-through hole and a second light-through hole that are spaced apart. The light-shielding wall is provided in the accommodating cavity, and the light-shielding wall is connected to the metal cover plate body and the first circuit board. The light-shielding wall is located between the first light-through hole and the second light-through hole, separating the light-emitting device from the photoelectric converter. In this way, since the light-shielding wall is made of metal material, the light-shielding wall has light-shielding properties, so the provision of a light-shielding wall between the light-emitting device and the photoelectric converter can reduce or even prevent the light emitted by the light-emitting device from directly incident on the light-emitting converter, thereby reducing the optical crosstalk between the light-emitting device and the photoelectric converter, and improving the detection accuracy of the photoelectric converter.

[0022] In an optional embodiment, the detection device may further include a light-shielding connection layer, disposed between the metal cover and the first circuit board, and connected to the metal cover and the first circuit board. This light-shielding connection layer allows the bottom of the metal cover to be bonded to the first circuit board, thereby reducing or preventing light from the light-emitting device from leaking from the bottom of the metal cover, thereby improving light utilization.

[0023] In one optional embodiment, the surface of the light-transmitting structure facing away from the first circuit board and the surface of the metal cover facing away from the first circuit board are joined to form an arc. This allows for a smooth transition between the surface of the light-transmitting structure facing away from the first circuit board and the surface of the metal cover facing away from the first circuit board, thereby improving user comfort when pressing.

[0024] In one optional embodiment, the detection device includes a metal coating, which covers the surface of the metal cover plate facing away from the first circuit board. In this way, the material of the metal coating can serve as a decorative element. Furthermore, the conductivity of the metal cover plate and the metal coating can be the same or different. In this case, the ECG electrode can include both the metal cover plate and the metal coating.

[0025] In an optional embodiment, the light-emitting device includes a first light-emitting component configured to emit at least one of red light or infrared light, with a first distance d1 between the first light-emitting component and the photoelectric converter. The red light emitted by the first light-emitting component and the infrared light emitted by the second light-emitting component have longer wavelengths, capable of reaching subcutaneous tissue, thereby detecting blood volume in arteries. Red light is primarily absorbed by oxyhemoglobin in the blood, while infrared light is primarily absorbed by hemoglobin and deoxyhemoglobin in the blood. Therefore, the processor can utilize the absorption difference between the red and infrared light captured by the photoelectric converter 23 to calculate blood oxygen saturation by measuring the ratio of hemoglobin to oxygen in the blood, thereby obtaining blood oxygen data. Furthermore, a second light-emitting component is configured to emit at least one of yellow light, green light, and blue light, with a second distance d2 between the second light-emitting component and the photoelectric converter, where d1>d2. The blue or green light emitted by the second light-emitting component has a shorter wavelength, capable of reaching the surface skin, thereby detecting blood volume in capillaries. The yellow light emitted by the second light-emitting component can reach the dermis, thereby detecting the blood volume in the arterioles.

[0026] In an optional embodiment, when the first spacing d1 satisfies the range of 3.5mm≤d1≤5.5mm, the light emitted by the first light-emitting component can be more fully and easily received by the photoelectric converter after being reflected by the user's skin, thereby making the signal collected by the photoelectric converter more accurate, and thus making the above-mentioned PPG data obtained by the electronic device more accurate. When the second spacing d2 satisfies the range of 3.0mm≤d1≤4.5mm, the above-mentioned PPG data obtained by the electronic device can be more accurate. In an optional embodiment, the light-transmitting structure includes a resin material, and the first circuit board, the light-emitting device, the photoelectric converter, the metal cover plate and the light-transmitting structure are an injection-molded integral structure. In this way, it can be formed into an injection-molded integral structure through a single processing process, such as an injection molding process. The injection-molded integral structure may include the light-emitting device, the photoelectric converter, the first circuit board, the metal cover plate and the light-transmitting structure of the detection device. The light-transmitting structure can not only connect the light-emitting device and the photoelectric converter to the metal cover and the first circuit board, but also wrap the surface and periphery of the light-emitting device and the photoelectric converter, thereby encapsulating the light-emitting device and the photoelectric converter, reducing the impact of external moisture and impurities on the performance of the light-emitting device and the photoelectric converter, and improving the waterproof and dustproof reliability of the entire detection device.

[0027] In one optional embodiment, the detection device includes multiple raised structures disposed on the surface of the metal cover facing away from the first circuit board. During the pressing process, the user can clearly feel the bumps and depressions of the touch surface. The positions of the raised structures can be matched with predetermined pressing positions, thereby guiding the user to press to the predetermined position and improving detection accuracy.

[0028] Another aspect of the embodiments of the present application provides an electronic device, which may include a middle frame and any of the above-mentioned detection devices. The detection device is connected to the middle frame, and a mounting groove is provided on the outer surface of the middle frame. A first circuit board, a light-emitting device, a photoelectric converter, a metal cover plate, and a light-transmitting structure are located in the mounting groove, and the first circuit board is closer to the bottom of the mounting groove relative to the metal cover plate. The above-mentioned electronic device has the same technical effects as the detection device provided in the above-mentioned embodiments, and will not be repeated here.

[0029] In an optional embodiment, a first mounting hole is provided at the bottom of the mounting groove and passes through the middle frame. The detection device includes a deformable sheet and a mounting post. In addition, the electronic device includes an elastic layer and a first retaining ring. The deformable sheet is located in the mounting groove, and the deformable sheet has a fixed end. The mounting post is located on the side of the deformable sheet facing away from the metal cover plate and passes through the first mounting hole. The first end of the mounting post is connected to the fixed end, and the second end of the mounting post extends out of the first mounting hole and is located in the middle frame. In addition, the elastic layer is located in the mounting groove, and the elastic layer is arranged between the deformable sheet and the bottom of the mounting groove. The elastic layer can reduce the probability of the deformable sheet undergoing plastic deformation under the action of user pressure. The first retaining ring is located in the middle frame, the first retaining ring is clamped to the second end of the mounting post, and the first retaining ring abuts against the middle frame. In this way, when the user presses the detection device, the first retaining ring can limit the vertical movement of the mounting post.

[0030] In one optional embodiment, the elastic layer comprises silicone or rubber. The modulus of the silicone or rubber can increase with increasing compression deformation. Thus, when the user applies greater pressure, the modulus of the compressed elastic layer increases, thereby supporting the deformable sheet and acting as a limiter, preventing the first and second cantilever ends of the deformable sheet from undergoing plastic deformation. Alternatively, the elastic layer comprises a soft rubber layer and a plurality of particles incorporated into the soft rubber layer. The hardness of the particles is greater than that of the soft rubber layer; wherein the soft rubber layer comprises silicone or rubber, and the particles comprise at least one of metal, plastic, or rubber. Thus, under the pressure of the user, the soft rubber layer undergoes elastic deformation under pressure, reducing the spacing between the particles and further causing at least some of the particles to directly contact each other. This increases the stiffness of the entire elastic layer, supporting the deformable sheet and acting as a limiter, preventing the first and second cantilever ends of the deformable sheet from undergoing plastic deformation.

[0031] In one optional embodiment, a first sealing groove is defined in the portion of the mounting post located within the first mounting hole. The electronic device includes a first sealing ring located within the first sealing groove, abutting against the walls of the first mounting hole and the first sealing groove. The first sealing ring seals the gap between the first mounting hole and the mounting post, reducing the chance of external moisture entering the interior of the midframe through the mounting groove and the first mounting hole, thereby improving product reliability.

[0032] In an optional embodiment, a first mounting hole that passes through the middle frame is provided at the bottom of the mounting groove, and the detection device includes a first pressure rod. In addition, the electronic device may further include a first adhesive layer and a second retaining ring. The first pressure rod passes through the first mounting hole, and the first pressure rod is arranged on the side of the first circuit board facing away from the metal cover plate. The first end of the first pressure rod is abutted or connected to the first circuit board, and the second end of the first pressure rod extends out of the first mounting hole and is located in the middle frame. In addition, the first bonding is located in the mounting groove, and the first adhesive layer is arranged between the first circuit board and the bottom of the mounting groove, and is connected to the first circuit board and the bottom of the mounting groove. The second retaining ring is located in the middle frame, the second retaining ring is clamped to the second end of the first pressure rod, and the second retaining ring is abutted against the middle frame. In this way, when the user presses the detection device, the first pressure rod can be limited in its vertical movement by the above-mentioned second retaining ring.

[0033] In an optional embodiment, the detection device further includes a deformable sheet located within the middle frame and having a fixed end. Furthermore, the electronic device further includes a threaded connector located within the middle frame, extending through the fixed end of the deformable sheet and connected to the middle frame to secure the deformable sheet.

[0034] In an optional embodiment, a first mounting hole and a second mounting hole are formed at the bottom of the mounting groove and pass through the middle frame. In addition, the detection device includes a first pressure rod and a second pressure rod. The first pressure rod passes through the first mounting hole, is arranged on the side of the first circuit board facing away from the metal cover plate, the first end of the first pressure rod abuts or is connected to the first circuit board, and the second end of the first pressure rod extends out of the first mounting hole and is located within the middle frame. The second pressure rod passes through the second mounting hole, is arranged on the side of the first circuit board facing away from the metal cover plate, the first end of the second pressure rod abuts or is connected to the first circuit board, and the second end of the second pressure rod extends out of the second mounting hole and is located within the middle frame. In addition, the electronic device also includes a first spring and a second spring. The first spring is located in the mounting groove, a portion of the first pressure rod passes through the first spring, and the two ends of the first spring respectively abut against the first pressure rod and the bottom of the mounting groove. The second spring is located in the mounting groove, a portion of the second pressure rod passes through the second spring, and the two ends of the second spring respectively abut against the second pressure rod and the bottom of the mounting groove. When the user does not press the detection device, the first spring and the second spring may be in a compressed state, so that the deformed deformable piece can return to its initial position after the user releases the pressing force on the metal cover.

[0035] In an optional embodiment, the first circuit board includes a flexible circuit board, and a third mounting hole that passes through the middle frame is provided at the bottom of the mounting groove. In addition, the electronic device further includes a plug, a second adhesive layer, and a second circuit board. The plug is arranged in the third mounting hole to seal the third mounting hole. The second adhesive layer is arranged in the third mounting hole and is located on the side of the plug away from the mounting groove, and the second adhesive layer is bonded to the plug and the middle frame. The second circuit board is arranged in the middle frame, and a portion of the flexible circuit board passes through the plug and the second adhesive layer, extends into the middle frame, and is electrically connected to the second circuit board. The plug can seal the third mounting hole to achieve waterproof and dustproof effects. The second adhesive layer can be glue, and the second adhesive layer is used to bond the plug to the middle frame.

[0036] Another aspect of the embodiments of the present application provides a control method for an electronic device, wherein the electronic device includes a detection device, the detection device having a key function and a health detection function, and the detection device includes a light-emitting device, a photoelectric converter, a metal cover, and a pressure-sensitive element. The control method includes: scanning the pressure-sensitive element at a first scanning frequency to identify a user pressing event on the detection device. Next, determine whether the health detection function is turned on. If the health detection function is turned on, the above-mentioned health detection function is executed. If the health detection function is not turned on, the key function is executed. The control method of the above-mentioned electronic device has the same technical effect as the electronic device provided by the aforementioned embodiment, and will not be repeated here.

[0037] In an optional embodiment, the above-mentioned health detection function is specifically: displaying a guidance image. Next, if the user's body directly presses the detection device, the pressure-sensitive element is scanned at a second scanning frequency to obtain the pressure value applied by the user on the metal cover, the light-emitting device and the photoelectric converter are started, and a voltage is applied to the metal cover to obtain the user's electrocardiogram signal. Among them, the second scanning frequency is greater than the first scanning frequency. Next, if the pressure value is greater than or equal to the first threshold value, and less than or equal to the second threshold value, the detection result is determined based on at least one of the pressure value, the output signal of the photoelectric converter and the electrocardiogram signal. Next, the above-mentioned detection result is displayed, and the detection result includes at least one of the blood oxygen value, heart rate value, electrocardiogram data and blood pressure value, thereby realizing the collection of blood oxygen, heart rate, electrocardiogram and blood pressure data to complete the health detection of the user.

It can also be understood as the electrical connection between different components in the circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals to transmit electrical signals; or, "electrical connection" can be an indirect electrical connection between two components through an intermediate medium; or, "electrical connection" can be an electrical connection between two components in an air / non-contact manner, for example, two components are electrically connected by capacitive coupling to transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to the connection relationship that limits the product structure.

[0089] In the embodiments of the present application, the descriptions "vertical" and "parallel" respectively indicate approximately vertical and approximately parallel within a certain error range, and the error range may be a range in which the deviation angle relative to absolute vertical and absolute parallel is less than or equal to 5°, 8° or 10°, respectively, and no specific limitation is made here.

[0090] In the embodiments of the present application, directional terms such as "up", "down", "left" and "right" may be defined including but not limited to the orientation relative to the components schematically placed in the drawings. It should be understood that these directional terms may be relative concepts, which are used for relative description and clarification, and may change accordingly according to changes in the orientation of the components in the drawings.

[0091] In the drawings of the embodiments of the present application, components are represented by guide lines with arrows; parts are represented by guide lines only; and hollow structures such as openings and holes are represented by guide lines with wavy lines at the ends.

[0092] An embodiment of the present application provides an electronic device that can be applied to various communication systems or communication protocols, such as: Bluetooth (BT) communication technology, global positioning system (GPS) communication technology, global system of mobile communication (GSM) communication technology, wireless fidelity (WiFi) communication technology, wideband code division multiple access wireless (WCDMA) communication technology, long term evolution (LTE), 5G communication technology, and other future communication technologies.

[0093] The electronic device in the embodiment of the present application may be a smart wearable device, for example, a human health detection wearable device that can detect the user's health parameters (for example, at least one of heart rate, blood oxygen, electrocardiogram, blood pressure, etc.). For example, the above-mentioned smart wearable device may be a smart watch, a smart bracelet, smart glasses, or a smart helmet. Alternatively, the above-mentioned electronic device may also be a mobile phone, a tablet computer (pad), a laptop computer, a smart home, a virtual reality (VR) electronic device, an augmented reality (AR) electronic device, etc. Alternatively, the electronic device may also be a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, an electronic device in a 5G network, or an electronic device in a future-evolved public land mobile communication network (PLMN), etc. The embodiment of the present application is not limited to this.

[0094] For the sake of convenience, the following description takes the electronic device 01 shown in FIG1A as an example of a smart watch capable of performing health detection. For example, the electronic device 01 may include a display 10, a middle frame 11, and a rear cover 12 as shown in FIG1B . Continuing with FIG1B , the display 10 may be arranged in the middle frame 11, the display surface of the display 10 is located on the side away from the rear cover 12, and the middle frame 11 may be arranged around the display 10. The display 10 may be a liquid crystal display (LCD), or an organic light emitting diode (OLED) display, or a micro or mini light emitting diode (LED) display.

[0095] This application does not limit the shape of the display screen 10. For example, the display surface of the display screen 10 can be circular or rectangular. The outline shapes of the middle frame 11 and the rear cover 12 can match the outline shape of the display screen 10. For the sake of convenience, the following description is based on the example of the outline shape of the display screen 10, the middle frame 11, and the rear cover 12 being circular.

[0096] On this basis, the above-mentioned electronic device 01 may also include components such as circuit boards, batteries, processors, sensors, microphones, and speakers. In some embodiments of the present application, components such as circuit boards, batteries, processors, sensors, microphones, and speakers may be arranged between the display screen 10 and the back shell 12. The above-mentioned middle frame 11 can support the entire electronic device 01. In some embodiments of the present application, the back shell 12 is respectively covered along the upper and lower edges of the middle frame 11 to form a shell or housing (housing) of the electronic device 01. Alternatively, the middle frame 11 and the back shell 12 may be connected as an integrally formed part to form a shell or housing of the electronic device 01. It should be understood that "shell or housing" can be used to refer to part or all of either the back shell 12 or the middle frame 11, or to refer to part or all of any combination of the back shell 12 or the middle frame 11.

[0097] For example, the processor may include one or more processing units, for example, the processor may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

[0098] In addition, in order to detect health parameters such as heart rate, blood oxygen, electrocardiogram, blood pressure, etc., the electronic device 01 may further include a detection device 20 as shown in FIG1A . The detection device 20 may be connected to the middle frame 11. For example, the outer surface of the detection device 20 may protrude from the outer surface of the middle frame 11. Alternatively, for another example, the outer surface of the detection device 20 may be flush with the outer surface of the middle frame 11, which is not limited in this application.

[0099] Based on this, when the electronic device 01 is a smart watch, as shown in FIG2A , the user can wear the electronic device 01 on the left hand and press the detection device 20 with the finger of the right hand (as shown in FIG2B ). Alternatively, the electronic device 01 can be worn on the right hand and the finger of the left hand can press the detection device 20. In this case, as shown in FIG2B , in some embodiments of the present application, when the user's finger presses the detection device 20, the detection device 20 can collect the user's heart rate, blood oxygen and electrocardiogram data. Alternatively, in other embodiments, the detection device 20 can also calculate the pressure value based on the above-mentioned heart rate, blood oxygen, electrocardiogram and other data. Alternatively, the detection device 20 can also collect the pressure value of the user pressing the detection device 20, so that the electronic device 01 can calculate the user's blood pressure value based on the above-mentioned heart rate, blood oxygen, electrocardiogram data and pressure value. In order to facilitate the detailed description of the structure of the detection device 20 below, the coordinate system XYZ of the detection device 20 is established in FIG2B , where the X direction can be the length direction of the detection device 20, the Y direction is the width direction of the detection device 20, and the Z direction is the height direction of the detection device 20.

[0100] The structure of the detection device 20 is described below by way of example. In some embodiments of the present application, as shown in FIG3 , the detection device 20 may include a first circuit board 21 , a light emitting device 22 , a photoelectric converter 23 , a metal cover 24 , and a light-transmitting structure 25 .

[0101] For example, the first circuit board 21 may include a flexible printed circuit (FPC), or, for another example, the first circuit board 21 may include a PCB. The light emitting device 22 may be an LED, an OLED, or a quantum dot light emitting diode (QLED), and the user emits detection light, such as at least one of visible light and infrared light. The photoelectric converter 23 may be a photodiode (PD) or a phototransistor, which is capable of receiving light reflected from the user's skin and performing photoelectric conversion.

[0102] The light-emitting device 22 and photoelectric converter 23 can be disposed on and electrically connected to the first circuit board 21. The first circuit board 21 can include circuitry for controlling the light-emitting device 22 and photoelectric converter 23. As shown in Figure 4 (a cross-sectional view taken along the dashed line O1-O2 in Figure 2B , where the dashed line O1-O2 is parallel to the X-direction), the light-emitting device 22 and photoelectric converter 23 can be located on the same side of the first circuit board 21. In this manner, the light-emitting device 22 and photoelectric converter 23 can form a photoplethysmograph (PPG) module.

[0103] The PPG module works by the following principle: blood circulation is driven by the contraction and relaxation of a beating heart. During contraction, blood flows to the periphery of the body, causing congestion in the area to be measured and an increase in blood volume. During diastole, blood from the area to be measured flows back into the heart, causing a decrease in blood volume. This generates a periodic signal, which may include a systolic peak and a diastolic peak. This periodic signal can be used to determine the heart rate (HR). Furthermore, the oxygen content in the blood is related to the hemoglobin content.

[0104] Based on this, human skin transmits and reflects visible light and infrared light. When light emitted by the light-emitting device 22 is irradiated by the skin, the blood flow in the skin (for example, changes in blood flow caused by heartbeat) and the amount of hemoglobin in the blood affect the amount of light absorbed, which in turn affects the skin's reflection of light. By collecting light reflected from the skin through the photoelectric converter 23, the temporal change pattern of light intensity related to blood volume in the human body can be detected, i.e., the photoplethysmogram. The photoplethysmogram can reflect the characteristics of blood flow and hemoglobin content, and thus parameters such as heart rate and blood oxygen can be obtained.

[0105] On this basis, as shown in Figure 4 , the metal cover plate 24 of the detection device 20 is mounted on the first circuit board 21. Furthermore, a housing cavity 200 can be formed between the metal cover plate 24 and the first circuit board 21, and the light-emitting device 22 and the photoelectric converter 23 can be disposed within the housing cavity 200. A first light hole 201 and a second light hole 202 are formed through the metal cover plate 24. The first light hole 201 exposes the light-emitting surface of the light-emitting device 22, and the second light hole 202 exposes the light-receiving surface of the photoelectric converter 23.

[0106] The light-emitting surface of the light-emitting device 22 is the surface from which the light-emitting device 22 emits light, and the light-receiving surface of the photoelectric converter 23 is the surface from which the photoelectric converter 23 receives light reflected from the skin. When a user's limb, such as a finger, touches the surface of the metal cover plate 24 facing away from the first circuit board 21 (i.e., the outer surface of the metal cover plate 24), the first light-through hole 201 on the metal cover plate 24 in FIG. 4 exposes the light-emitting surface of the light-emitting device 22. This allows light emitted by the light-emitting device 22 to pass through the first light-through hole 201 and illuminate the user's finger. Furthermore, because the second light-through hole 202 on the metal cover plate 24 exposes the light-receiving surface of the photoelectric converter 23, light reflected from the user's finger can pass through the second light-through hole 202 and be incident on the light-receiving surface of the photoelectric converter 23, thereby enabling the collection of emitted light and, thus, obtaining the aforementioned PPG data.

[0107] In addition, the human skin, from the outside to the inside, may include, in sequence, the epidermis 100, the dermis 101, and the subcutaneous tissue 102 as shown in FIG5 . Based on this, in some embodiments of the present application, the light-emitting device 22 may emit visible light of different wavelengths, such as at least one of blue light, green light, yellow light, and red light. In addition, the light-emitting device 22 may also emit infrared light. Based on this, the light-emitting device 22 may include a first light-emitting component 221 and a second light-emitting component 222 as shown in FIG5 . The first light-emitting component 221 may emit at least one of red light or infrared light, and the second light-emitting component 222 may emit at least one of the above-mentioned yellow light, green light, and blue light. The wavelengths of the above-mentioned visible light and infrared light and the detection targets are shown in Table 1.

[0108] Table 1

[0109] Continuing with Table 1, as shown in FIG5 , the light emitted by the light-emitting device 22 has different wavelengths, reaches different depths of the skin, and detects different targets. For example, the blue light or green light (thin solid lines in FIG5 represent yellow light or green light) emitted by the second light-emitting component 222 has a shorter wavelength and can reach the epidermis 100, thereby detecting blood volume in capillaries (the shaded portion of the epidermis 100 in FIG5 ). The yellow light (thin dashed lines in FIG5 ) emitted by the second light-emitting component 222 can reach the dermis 101, thereby detecting blood volume in arterioles (the shaded portion of the dermis 101 in FIG5 ). The red light emitted by the first light-emitting component 221 and the infrared light emitted by the second light-emitting component 222 (thick solid lines in FIG5 ) have longer wavelengths and can reach the subcutaneous tissue 102, thereby detecting blood volume in arteries (the shaded portion of the subcutaneous tissue 102 in FIG5 ).

[0110] In this way, the processor in the electronic device 01 can obtain PPG signals from blood vessels in different layers of the skin from the photoelectric converter 23. By comprehensively processing the multi-dimensional PPG signals, more accurate PPG data, such as the aforementioned blood oxygen and heart rate data, can be obtained. Red light is primarily absorbed by oxyhemoglobin in the blood, while infrared light is primarily absorbed by hemoglobin and deoxyhemoglobin in the blood. Therefore, the processor can use the difference in absorption between the red and infrared light collected by the photoelectric converter 23 to calculate blood oxygen saturation by measuring the ratio of hemoglobin to oxygen in the blood, thereby obtaining blood oxygen data.

[0111] Continuing with FIG. 5 , in some embodiments of the present application, a first distance d1 may be provided between the first light-emitting component 221 and the photoelectric converter 23. The first distance d1 may satisfy a size range of 3.5 mm ≤ d1 ≤ 5.5 mm. The first distance d1 may be the distance between the center position (or the center position of light emission) of the first light-emitting component 221 and the center position of the photoelectric converter 23. When the first distance d1 satisfies the range of 3.5 mm ≤ d1 ≤ 5.5 mm, the light emitted by the first light-emitting component 221 can be more fully and easily received by the photoelectric converter 23 after being reflected by the user's skin, thereby making the signal collected by the photoelectric converter 23 more accurate, and thus making the PPG data obtained by the electronic device 01 more accurate. For example, the first distance d1 may be 3.5 mm, 4 mm, 4.5 mm, 5 mm, or 5.5 mm.

[0112] Based on this, in some embodiments of the present application, since the blood oxygen data is related to the absorption difference between red light and infrared light, as shown in Figure 6 (a top view obtained along the B direction in Figure 5), the first light-emitting component 221 may include a first light source 2211 for emitting red light and a second light source 2212 for emitting infrared light. The first light source 2211 and the second light source 2212 can be at least one of self-luminous devices such as LED, OLED, QLED, etc. There is the above-mentioned first spacing d1 between any one of the first light source 2211 and the second light source 2212 and the photoelectric converter 23. Along the Y direction, the present application does not limit the position and spacing of the first light source 2211 and the second light source 2212.

[0113] 5 , a second spacing d2 is provided between the second light-emitting component 222 and the photoelectric converter 23. The second spacing d2 can satisfy a size range of 3.0 mm ≤ d1 ≤ 4.5 mm. Similarly, the second spacing d2 can be the distance between the center position of the second light-emitting component 222 (or the center position of the light emission) and the center position of the photoelectric converter 23. When the second spacing d2 satisfies the range of 3.0 mm ≤ d1 ≤ 4.5 mm, the PPG data acquired by the electronic device 01 can be more accurate. For example, the second spacing d2 can be 3 mm, 3.5 mm, 4 mm, or 4.5 mm.

[0114] Based on this, it can be seen from Table 1 that both blue light and green light can reach the epidermis 100 to detect the PPG signal in the capillary blood light. Therefore, the second light-emitting component 222 can include a third light source 2221 and a fourth light source 2222 as shown in Figure 6. The third light source 2221 can be used to emit blue light or green light, and the fourth light source 2222 is used to emit yellow light. Similarly, the third light source 2221 and the fourth light source 2222 can be at least one of self-luminous devices such as LED, OLED, QLED, etc. There is the second spacing d2 between any one of the third light source 2221 and the fourth light source 2222 and the photoelectric converter 23. Along the Y direction, this application does not limit the position and spacing of the third light source 2221 and the fourth light source 2222.

[0115] In addition, as shown in Figure 7 (a cross-sectional view obtained by cutting along the dotted line O1-O2 in Figure 2B), the metal cover 24 is electrically connected to the first circuit board 21 so that the metal cover 24 can transmit electrical signals to the first circuit board 21. Therefore, the metal cover 24 can be used as an electrocardiogram (ECG) electrode. Based on this, since each beat of the heart will cause tiny electric waves on the surface of the skin, when the user's limbs, such as fingers, touch the outer surface of the metal cover 24, the above-mentioned electric waves can be collected by the metal cover 24 and amplified and processed by the processor in the electronic device 01, and an electrocardiogram can be obtained. The electrocardiogram can be used to know the health of the user's heart, for example, to determine whether the heart activity is normal, slow, fast or irregular.

[0116] The above is an example of detecting ECG data using the example of a user directly contacting the outer surface of the metal cover 24. In other embodiments of the present application, the detection device 20 may further include a metal coating 241 as shown in Figure 7. The metal coating 241 may cover the outer surface of the metal cover 24, that is, the surface of the metal cover 24 facing away from the first circuit board 21. In this way, the material of the metal coating 241 can be set to serve as an appearance decoration. In addition, the conductivity of the metal cover 24 and the metal coating 241 may be the same or different. In this case, the above-mentioned ECG electrode may include a metal cover 24 and a metal coating 241. For the convenience of explanation in the following embodiments, the metal coating 241 is not shown in some of the drawings.

[0117] In order to electrically connect the metal cover plate 24 to the circuit board 21, in some embodiments of the present application, as shown in FIG8A , the detection device 20 may further include a conductive silicone rubber 30. The conductive silicone rubber 30 may be disposed between the metal cover plate 24 and the first circuit board 21. As shown in FIG8B (a cross-sectional view taken along the dotted line O1-O2 in FIG2B ), a first end (e.g., the upper end along the Z direction) of the conductive silicone rubber 30 is electrically connected to the metal cover plate 24, and a second end (e.g., the lower end along the Z direction) of the conductive silicone rubber 30 is welded to the first circuit board 21. In this case, the two ends of the conductive silicone rubber 30 can be welded to pads on the metal cover plate 24 and the first circuit board 21, respectively, through a welding process. Thus, the metal cover plate 24 and the first circuit board 21 can be electrically connected via the conductive silicone rubber 30, thereby achieving signal interconnection between the conductive silicone rubber 30 and the first circuit board 21.

[0118] Alternatively, in other embodiments of the present application, as shown in FIG9 , the detection device 20 may further include a conductive adhesive 31, which is disposed between the metal cover 24 and the first circuit board 21, and the conductive adhesive 31 is bonded to the metal cover 24 and the copper leakage portion 210 of the first circuit board 21, and the conductive adhesive 31 can be electrically connected to the metal cover 24 and the first circuit board 21. In this case, the portion of the first circuit board 21 electrically connected to the conductive adhesive 31 does not need to be provided with a pad, and the conductive adhesive 31 is bonded to the copper leakage portion 210 of the first circuit board 21, and the side of the conductive adhesive 31 facing away from the copper leakage portion 210 can be bonded to the metal cover 24, so that the metal cover 24 can achieve signal interconnection with the first circuit board 21 through the conductive adhesive 31. For example, the copper leakage portion 210 of the first circuit board 21 can be a portion of the metal copper layer exposed in the first circuit board 21.

[0119] Alternatively, in other embodiments of the present application, the detection device 20 further includes a metal shrapnel 32 as shown in FIG10A or FIG10B. The metal shrapnel 32 can be disposed in the accommodating cavity 200 (as shown in FIG7). For example, as shown in FIG10A, the first end of the metal shrapnel 32 (i.e., the end facing the metal cover plate 24) is welded to the metal cover plate 24, and the second end of the metal shrapnel 32 (i.e., the end facing the first circuit board 21) abuts against the copper leakage portion 210 of the first circuit board 21. During the abutment between the second end of the metal shrapnel 32 and the copper leakage portion 210 of the first circuit board 21, the metal shrapnel 32 can be elastically deformed, and the deformed metal shrapnel 32 can be in closer contact with the copper leakage portion 210 of the first circuit board 21. Alternatively, as shown in FIG10B, the second end of the metal shrapnel 32 (i.e., the end facing the first circuit board 21) is welded to the first circuit board 21, and the first end of the metal shrapnel 32 (i.e., the end facing the metal cover plate 24) abuts against the metal cover plate 24. Similarly, when the first end of the metal spring 32 abuts the metal cover 24, the metal spring 32 can be elastically deformed, and the deformed metal spring 32 can be in closer contact with the metal cover 24. In this way, the metal cover 24 can achieve signal interconnection with the first circuit board 21 through the metal spring 32.

[0120] The above is an example of the electrical connection between the metal cover plate 24 and the first circuit board 21 and does not constitute a limitation on the electrical connection method. In addition, the present application does not limit the position of the electrical connection between the metal cover plate 24 and the first circuit board 21.

[0121] As can be seen from the above, the user's blood oxygen, heart rate and other PPG data can be obtained through the above-mentioned PPG module (including the light-emitting device 22 and the photoelectric converter 23), and the ECG data can be obtained through the ECG electrode, such as the metal cover 24, or the metal cover 24 and the metal plating 241. Based on this, for example, the pulse wave transit time (PTT) can be obtained according to the above-mentioned PPG data and ECG data. The pulse wave transmission speed can be obtained according to the PPT and parameters such as the user's height and weight, and the systolic and diastolic pressures of the user's pulse can be obtained according to the pulse wave transmission speed, thereby realizing non-invasive continuous blood pressure measurement. Compared with the cuff-type blood pressure monitor, the detection device 20 provided in the present application does not require the user to wear a sleeve on the arm during the process of detecting blood pressure. The user only needs to touch the metal cover 24 with his fingers, thereby improving the comfort and convenience of blood pressure detection.

[0122] As can be seen from the above, the detection device 20 provided in the embodiment of the present application integrates a PPG module (light-emitting device 22 and photoelectric converter 23) and ECG electrodes. In addition, in order to connect the PPG module (light-emitting device 22 and photoelectric converter 23), ECG electrodes and the first circuit board 21, the detection device 20 may further include the light-transmitting structure 25 as shown in FIG8B . The light-transmitting structure 25 may be filled in the first light-transmitting hole 201, the second light-transmitting hole 202 and the accommodating cavity 200 (as shown in FIG7 ).

[0123] Based on this, to improve user comfort when pressing the detection device 20, as shown in Figure 8B, the surface of the light-transmitting structure 25 facing away from the first circuit board 21 can be spliced ​​into a curved surface with the surface of the metal cover plate 24 facing away from the first circuit board 21. In this way, the surface of the light-transmitting structure 25 facing away from the first circuit board 21 can smoothly transition to the intersection with the surface of the metal cover plate 24 facing away from the first circuit board 21, thereby improving user comfort when pressing.

[0124] Continuing with FIG8B , the aforementioned light-transmitting structure 25 encloses the light-emitting device 22 and the photoelectric converter 23 and is connected to the light-emitting device 22, the photoelectric converter 23, the first circuit board 21, and the metal cover 24. The portion of the light-transmitting structure 25 filling the first light-through hole 201 and the accommodating cavity 200 connects the light-emitting device 22 to the first circuit board 21 and the metal cover 24. This light-transmitting structure 25 has light-transmitting properties, thereby reducing the impact on light emitted from the light-emitting surface of the light-emitting device 22. Similarly, the portion of the light-transmitting structure 25 filling the second light-through hole 202 and the accommodating cavity 200 connects the photoelectric converter 23 to the first circuit board 21 and the metal cover 24, and can also reduce the impact on light reflected from the skin onto the light-receiving surface of the photoelectric converter 23. For convenience of description, the portion of the light-transmitting structure 25 enclosing the light-emitting device 22 will be referred to as the first light-transmitting structure 251, and the portion of the light-transmitting structure 25 enclosing the photoelectric converter 23 will be referred to as the second light-transmitting structure 252.

[0125] For example, the light transmittance of the above-mentioned light-transmitting structure 25 can be greater than or equal to 80%. On this basis, since the light-transmitting structure 25 is light-transmitting, in order to reduce the optical crosstalk between the light-emitting device 22 and the photoelectric converter 23, for example, as shown in Figure 8B, the metal cover 24 can include a metal cover body 243 and a light-shielding wall 244. Among them, the metal cover body 243 can be covered on the first circuit board 21, and the metal cover body 243 is electrically connected to the first circuit board 21. The electrical connection method is the same as described above and will not be repeated here. In addition, the metal cover body 243 can be provided with the above-mentioned first light-through hole 201 and the second light-through hole 202 set at intervals, and a part of the metal cover body 243 is spaced between the first light-through hole 201 and the second light-through hole 202.

[0126] In addition, a light-shielding wall 244 is disposed within the accommodating cavity 200 (as shown in FIG7 ), and the light-shielding wall 244 can be connected to the metal cover body 243 and the first circuit board 21. As shown in FIG8C , the light-shielding wall 244 is located between the first light-through hole 201 and the second light-through hole 202, and can separate the light-emitting device 22 shown in FIG8B from the photoelectric converter 23.

[0127] For example, the metal cover body 243 and the light-shielding wall 244 can be made of the same material. For example, the light-shielding wall 244 can be made of a metal material, and the light-shielding wall 244 can be connected to the metal cover body 243 to form an integral structure. For example, the integral structure can be formed by a single metal casting process, a metal injection process, a 3D printing process, or a die-casting process. In this way, since the light-shielding wall 244 is made of a metal material, it has light-shielding properties. Therefore, the provision of the light-shielding wall 244 between the light-emitting device 22 and the photoelectric converter 23 can reduce or even prevent the light emitted by the light-emitting device 22 from directly entering the light-emitting converter 23, thereby reducing the optical crosstalk between the light-emitting device 22 and the photoelectric converter 23 and improving the detection accuracy of the photoelectric converter 23. Alternatively, the light-shielding wall 244 can also be made of a non-metallic light-shielding material and connected to the metal cover body 243 by bonding, snap-fitting, or threading.

[0128] Continuing with FIG8A , to reduce or prevent light emitted by the light-emitting device 22 from leaking from the bottom of the metal cover 24, i.e., toward the first circuit board 21, the detection device 20 may further include a light-shielding connection layer 27 disposed between the metal cover 24 and the first circuit board 21. As shown in FIG8B , the light-shielding connection layer 27 may be connected to the light-shielding barrier 244 and the first circuit board 21. For example, the light-shielding connection layer 27 may be a light-shielding adhesive layer or light-shielding tape. This allows the light-shielding connection layer 27 to bond the bottom of the metal cover 24 to the first circuit board 21, thereby reducing or preventing light emitted by the light-emitting device 22 from leaking from the bottom of the metal cover 24 and improving light utilization. To this end, as shown in FIG8A , the light-shielding connection layer 27 may be provided with a relief hole 271 to accommodate the light-emitting device 22, the photoelectric converter 23, and components for electrically connecting the metal cover 24 to the first circuit board 21, such as the conductive silicone rubber 30.

[0129] In summary, as shown in FIG11A , the light-emitting device 22 and the photoelectric converter 23 are covered in the metal cover 24, and the light-transmitting structure 25 can cover the light-emitting surface of the light-emitting device 22 and the light-receiving surface of the photoelectric converter 23, thereby ensuring the normal operation of the light-emitting device 22 and the photoelectric converter 23. In addition, the light-transmitting structure 25 can also cover the side surfaces of the light-emitting device 22 and the photoelectric converter 23 (parallel to the thickness direction of the detection device 20, the Z direction). As can be seen from FIG11A (a cross-sectional view obtained by cutting along the dotted line O1-O2 in FIG2B ) and FIG11B (a cross-sectional view obtained by cutting along the dotted line A1-A2 in FIG11A ), the light-emitting device 22 and the photoelectric converter 23, except for the surface facing the first circuit board 21, can be covered by the light-transmitting structure 25, so that the light-transmitting structure 25 can wrap the light-emitting device 22 and the photoelectric converter 23, and then the light-transmitting structure 25 can be connected to the light-emitting device 22, the photoelectric converter 23, the first circuit board 21 and the metal cover 24 to form an integrated structural component. Based on this, when the above-mentioned light-transmitting structure 25 is made of resin material, it can be formed into an injection-molded integrated structure 220 through a one-time processing process, such as an injection molding process. The injection-molded integrated structure 220 may include the light-emitting device 22 of the detection device 20, the photoelectric converter 23, the first circuit board 21, the metal cover plate 24 and the light-transmitting structure 25.

[0130] In the related art shown in FIG12A , a transparent plate 110 is provided above the LED and PD arranged on the PCB. ECG electrodes (not shown) can be provided on the transparent plate 110, and the transparent plate can carry the ECG electrodes. The transparent plate 110 is bonded to the bracket 112 via an adhesive layer 111. In this case, in order to ensure the bonding firmness and waterproof performance between the transparent plate 110 and the bracket 112, the length of the adhesive layer 111 along the X direction needs to meet certain requirements, and the length of the bracket 112 along the X direction also needs to meet the requirements of the groove (for placing the adhesive layer 111) and supporting the transparent plate 110. Therefore, the length of the entire device along the X direction is relatively wide. Similarly, as shown in FIG12B (a cross-sectional view obtained by cutting along the dotted line B1-B2 in FIG12A ), also considering the width requirements of the adhesive layer 111 and the bracket 112 supporting the transparent plate 110, the width of the entire device along the Y direction is relatively wide.

[0131] Based on this, on the one hand, relative to the scheme of Figure 12A, the above-mentioned bracket 112, transparent plate 110 and adhesive layer 111 do not need to be provided in the embodiment of the present application. When the emission angle θ of the light-emitting device 22 (as shown in Figure 11B) is the same, as shown in Figure 11A, the detection device 20 provided in the embodiment of the present application can connect the metal cover plate 24 serving as the ECG electrode with the light-emitting device 22 and the photoelectric converter 23 through the light-transmitting structure 25 embedded in the metal cover plate 24. Therefore, in the length direction of the detection device (i.e., the X direction), there is no need to consider the length requirements of the adhesive layer and the bracket supporting the transparent plate. Similarly, relative to the scheme of Figure 12B, as shown in Figure 11B, in the detection device 20 provided in the embodiment of the present application, in the width direction of the detection device (i.e., the Y direction), there is no need to consider the length requirements of the adhesive layer and the bracket supporting the transparent plate. Therefore, the length and width dimensions of the detection device 20 can be reduced. In addition, in the embodiment of the present application, the light-transmitting structure 25 embedded in the metal cover plate 24 can cover the surface of the light-emitting device 22 and the photoelectric converter 23 facing away from the first circuit board 21. Therefore, there is no need to set the transparent plate 110 in Figure 12A, thereby reducing the size of the detection device in the height direction (i.e., the Z direction). In this way, the three-dimensional dimensions of the detection device 20 are all reduced, thereby achieving the purpose of miniaturization of the detection device 20. In this case, when the detection device 20 with the above-mentioned miniaturized design is applied to the electronic device 01, it is beneficial to reduce the size of the electronic device 01, thereby alleviating the problem of the large size of the device with health sign detection function.

[0132] On the other hand, in the detection device 20 which is an integrated structural part formed by the above-mentioned injection molding process, the light-transmitting structure 25 can not only connect the light-emitting device 22 and the photoelectric converter 23 with the metal cover 24 and the first circuit board 21, but also wrap the surface and periphery of the light-emitting device 22 and the photoelectric converter 23, thereby encapsulating the light-emitting device 22 and the photoelectric converter 23, reducing the impact of external water vapor and impurities on the performance of the light-emitting device 22 and the photoelectric converter 23, and improving the waterproof and dustproof reliability of the entire detection device 20.

[0133] As can be seen from the above, the detection device 20 provided in an embodiment of the present application, as shown in Figure 11A, includes a PPG module (including a light-emitting device 22 and a photoelectric converter 23) and ECG electrodes (including a metal cover plate 24). The PPG module, ECG electrodes, and first circuit board 21 can be connected via a light-transmitting structure 25 to form an injection-molded integral structural member 220. Based on this, it can be seen from the above that in some embodiments of the present application, when a user's finger presses the metal cover plate 24, the PPG module can obtain the user's PPG data, such as heart rate and blood oxygen data. The ECG electrodes can obtain the user's electrocardiogram (ECG) data. The user's blood pressure can be obtained based on the PPG and ECG data. Alternatively, in other embodiments of the present application, the pressure value when the user presses the metal cover plate 24 can be incorporated into the process of obtaining the user's blood pressure data. The user's blood pressure can be calculated by combining the PPG data, ECG data, and pressure value, thereby further improving the accuracy of blood pressure detection. In this case, to obtain the pressure value when the user presses the metal cover plate 24, the detection device 20 can also include a pressure sensing module. The structure of this pressure sensing module is described below with an example.

[0134] In some embodiments of the present application, as shown in FIG13 , the pressure sensing module 400 of the detection device 20 may include a first pressure rod 41, a second pressure rod 42, a deformable sheet 43, and a pressure-sensitive element 44. The first pressure rod 41 and the second pressure rod 42 are disposed on the side of the first circuit board 21 facing away from the metal cover 24. For example, the first circuit board 21 may include an FPC 2101 and a support plate 2102, with the support plate 2102 disposed on the side of the FPC 2101 facing away from the metal cover 24. The side of the FPC 2101 facing the metal cover 24 may be connected to the injection-molded integral structural member 220 via an adhesive layer, and the side of the FPC 2101 facing away from the metal cover 24 may be connected to the support plate 2102 via an adhesive layer. The rigidity of the support plate 2102 is greater than that of the FPC 2101, thereby enabling support for the FPC 2101. Based on this, the first pressure rod 41 and the second pressure rod 42 may be disposed on the side of the support plate 2102 facing away from the metal cover 24. When the user presses the metal cover 24 , the force transmitted to the first circuit board 21 may be transmitted to the first pressing rod 41 and the second pressing rod 42 through the support plate 2102 .

[0135] In addition, as shown in Figure 13, the deformable sheet 43 is arranged on the side of the first pressure rod 41 away from the first circuit board 21. The deformable sheet 43 has a first cantilever end 431, a fixed end 430 and a second cantilever end 432. The fixed end 430 is located between the first cantilever end 431 and the second cantilever end 432. The deformable sheet 43 is a cantilever end structure. The fixed end 430 is used to fix the deformable sheet 43, for example, the deformable sheet 43 is fixed to the middle frame 11 shown in Figure 14A. In this case, as shown in Figure 13, the first end (for example, the upper end) of the first pressure rod 41 can be abutted or connected to the first circuit board 21, and the second end (for example, the lower end) of the first pressure rod 41 can be abutted or connected to the first cantilever end 431 of the deformable sheet 43. The first end (eg, the upper end) of the second pressure rod 42 may abut against or be connected to the first circuit board 21 , and the second end (eg, the lower end) of the second pressure rod 42 may abut against or be connected to the second cantilever end 432 of the deformation piece 43 .

[0136] For example, as shown in FIG14A (a cross-sectional view taken along the dotted line O1-O2 in FIG2B ), the second end (e.g., the lower end) of the first pressure rod 41 can be connected to the first cantilever end 431 of the deformable sheet 43 as an integral structural member, and the second end (e.g., the lower end) of the second pressure rod 42 can be connected to the second cantilever end 432 of the deformable sheet 43 as an integral structural member. Based on this, during the assembly of the detection device 20, the first end (e.g., the upper end) of the first pressure rod 41 can contact the first circuit board 21, such as the support plate 2102 in the first circuit board 21, and the first end (e.g., the upper end) of the second pressure rod 42 can contact the first circuit board 21, such as the support plate 2102 in the first circuit board 21.

[0137] Alternatively, the first end (e.g., the upper end) of the first pressure rod 41 can be connected to the first circuit board 21, such as the support plate 2102 in the first circuit board 21, as an integral structural member, and the first end (e.g., the upper end) of the second pressure rod 42 can be connected to the first circuit board 21, such as the support plate 2102 in the first circuit board 21, as an integral structural member. Based on this, during the assembly of the detection device 20, the second end (e.g., the lower end) of the first pressure rod 41 can contact the first cantilever end 431 of the deformable sheet 43, and the second end (e.g., the lower end) of the second pressure rod 42 can contact the second cantilever end 432 of the deformable sheet 43.

[0138] Continuing with FIG14A , the pressure-sensitive element 44 covers at least a portion of the first cantilever end 431 of the deformable piece 43 and also covers at least a portion of the second cantilever end 432. Furthermore, the pressure-sensitive element 44 is electrically connected to the first circuit board 21, for example, the FPC 2101 within the first circuit board 21. Thus, when a user's finger presses the metal cover 24 downward in the Z direction, the external force applied by the user can be transmitted through the metal cover 24 to the first circuit board 21, and then through the first circuit board 21 to the first and second pressure bars 41, 42 located below the first circuit board 21. Because the first pressure rod 41 and the second pressure rod 42 are respectively in contact with or connected to the first cantilever end 431 and the second cantilever end 432 of the deformable piece 43, the fixed end 430 located between the first cantilever end 431 and the second cantilever end 432 of the deformable piece 43 fixes the deformable piece 43 to a component, such as the middle frame 11, so that under the pressing action of the first pressure rod 41 and the second pressure rod 42, the first cantilever end 431 and the second cantilever end 432 of the deformable piece 43 shown in Figure 14B can be deformed downward along the Z direction. In addition, because the pressure-sensitive element 44 covers at least a portion of the first cantilever end 431 and at least a portion of the second cantilever end 432, the pressure-sensitive element 44 can utilize the piezoelectric induction principle to convert the deformation of the first cantilever end 431 and the second cantilever end 432 into an electrical signal, and transmit it to the first circuit board 21 (shown in Figure 14A) electrically connected to the pressure-sensitive element 44, thereby detecting the user's pressing force.

[0139] As can be seen from the above, the fixed end 430 of the deformable sheet 43 is used to fix the deformable sheet 43. The following example illustrates the fixing method of the fixed end 430. For example, when the above-mentioned detection device 20 is arranged on the middle frame 11, the detection device 20 can be connected to the middle frame 11, the above-mentioned injection-molded integral structural member 220 (including the light-emitting device 22, the photoelectric converter 23, the first circuit board 21, the metal cover 24 and the light-transmitting structure 25) and the above-mentioned deformable sheet 43 can be arranged on the outside of the middle frame 11, and the fixed end 430 of the deformable sheet 43 can be connected to the inside of the middle frame 11.

[0140] Based on this, in some embodiments of the present application, as shown in FIG15 , a mounting groove 300 is defined on the outer surface of the middle frame 11, and a first mounting hole 301 is defined at the bottom of the mounting groove 300, extending through the middle frame 11. Furthermore, as shown in FIG16A (a cross-sectional view taken along the dashed line O1-O2 in FIG2B ), the aforementioned injection-molded integral structural member 220 (including the light-emitting device 22, the photoelectric converter 23, the first circuit board 21, the metal cover 24, and the light-transmitting structure 25), as well as the first pressure rod 41, the second pressure rod 42, the deformable plate 43, and the pressure-sensitive element 44 can be disposed within the mounting groove 300, with the first circuit board 21 positioned closer to the bottom of the mounting groove 300 relative to the metal cover 24. The pressure-sensitive element 44 can be disposed on the side of the deformable plate 43 facing the metal cover 24. Alternatively, in other embodiments, the pressure-sensitive element 44 can be disposed on the side of the deformable plate 43 facing away from the metal cover 24.

[0141] In addition, in order to fix the fixed end 430 of the deformable sheet 43, the above-mentioned detection device also includes a first retaining ring 51 and a first sealing ring 52 as shown in Figure 16A. The mounting post 50 is located on the side of the deformable sheet 43 facing away from the metal cover 24. The first end (for example, the upper end) of the mounting post 50 is connected to the fixed end 430 of the deformable sheet 43, and the second end (for example, the lower end) of the mounting post 50 is used to fix the detection device. For example, the second end of the mounting post 50 extends into the middle frame 11 through the first mounting hole 301 (as shown in Figure 15), and the first retaining ring 51 is located in the middle frame 11. The first retaining ring 51 is clamped to the second end of the mounting post 50, and the first retaining ring 51 abuts against the middle frame 11. The mounting post 50 and the pressure-sensitive element 44 are respectively arranged on opposite sides of the deformable sheet, so that the setting position of the pressure-sensitive element 44 will not affect the setting position of the mounting post 50. In this way, when a user presses the detection device 20, the first retaining ring 51 can limit the movement of the mounting post 50 in the Z direction. In addition, when the first retaining ring 51, which is engaged with the second end of the mounting post 50, abuts the middle frame 11, the mounting post 50 can be fixed to the middle frame 11 through the first retaining ring 51. Because the first end of the mounting post 50 is connected to the fixed end 430 of the deformable piece 43, the fixed end of the deformable piece 43 can be fixed to the middle frame 11 through the mounting post 50.

[0142] On this basis, as shown in FIG16A , the portion of the mounting post 50 located within the first mounting hole 301 (as shown in FIG15 ) is provided with a first sealing groove 501. The first sealing ring 52 can be located within the first sealing groove 501. The first sealing ring 52 abuts against the wall of the first mounting hole 301 (as shown in FIG15 ) and the wall of the first sealing groove 501. Thus, the first sealing ring 52 can seal the gap between the first mounting hole 301 and the mounting post 50, reducing the chance of external moisture entering the interior of the middle frame 11 through the mounting groove 300 and the first mounting hole 301, thereby improving product reliability.

[0143] In addition, the bottom of the mounting slot 300 shown in Figure 15 is provided with a third mounting hole 303 that passes through the middle frame. A portion of the FPC 2101 (shown in Figure 16A) can be passed through the third mounting hole 303 and then disposed in the middle frame 11. Based on this, the electronic device 01 can also include a plug 54, a second adhesive layer 55, and a second circuit board 60 as shown in Figure 16A. Among them, the plug 54 can be disposed in the third mounting hole 303 (shown in Figure 15), and the plug 54 can block the third mounting hole 303. In addition, the second adhesive layer 55 can be disposed in the third mounting hole 303 and is located on the side of the plug 54 facing away from the mounting slot 300 (shown in Figure 16A). The second adhesive layer 55 can be bonded to the plug 54 and the middle frame 11. The second circuit board 60 is disposed in the middle frame 11, and a portion of the FPC 2101 passes through the plug 54 and the second adhesive layer 55 and extends into the middle frame 11 to be electrically connected to the second circuit board 60.

[0144] The second circuit board 60 can be referred to as a motherboard, on which a processor can be mounted. When the portion of the FPC 2101 located within the middle frame 11 is electrically connected to the motherboard, the processor can transmit signals through the FPC 2101 to the metal cover 24, the light-emitting device 22, the photoelectric converter 23, and the pressure-sensitive element 44 in the detection device 20. Furthermore, the plug 54 can seal the third mounting hole 303 (as shown in FIG. 15 ) to achieve waterproof and dustproof properties. The second adhesive layer 55 can be glue, which is used to bond the plug 54 to the middle frame 11.

[0145] As can be seen from the above, the deformable sheet 43 shown in Figure 16A can be deformed under the pressure applied by the user. For example, the deformable sheet 43 can be a metal sheet, and the material includes alloy steel, for example, at least one of titanium alloy and aluminum alloy. In addition, when the user cancels the pressing force, the deformable sheet 43 needs to return to its original position, so the above-mentioned deformable sheet 43 needs to undergo elastic deformation. As can be seen from the above, the size of the detection device provided in the embodiment of the present application is relatively small, so the size of the deformable sheet 43 is also reduced accordingly. However, after the size of the deformable sheet 43 is reduced, after the external force is applied to compress the deformable sheet 43, the deflection of the deformable sheet 43 will be reduced, so that plastic deformation is likely to occur when the external force is large.

[0146] Based on this, in order to reduce the probability of plastic deformation of the deformable piece 43 under the action of user pressure, the above-mentioned detection device may further include an elastic layer 53 as shown in FIG16A . The elastic layer 53 may be located within the mounting groove 300, and the elastic layer 53 may be provided between the deformable piece 43 and the bottom of the mounting groove 300. For example, the elastic layer 53 may be located on the side of the first cantilever end 431 and the second cantilever end 432 of the deformable piece 43 facing away from the metal cover plate 24. The elastic layer 53 may cover a portion of the first cantilever end 431 and the second cantilever end 432, or may completely cover the first cantilever end 431 and the second cantilever end 432.

[0147] In some embodiments of the present application, the elastic layer 53 may include silicone or rubber. The modulus of the silicone or rubber may increase with increasing compression deformation. In this way, when the user applies greater pressure, the modulus of the compressed elastic layer 53 increases, thereby supporting the deformable sheet 43 and achieving a limiting effect, so that the first cantilever end 431 and the second cantilever end 432 of the deformable sheet 43 are not easily plastically deformed. For example, when the distance between the deformable sheet 43 and the middle frame 11 is small, room temperature vulcanized silicone rubber (RTV) can be used to dispense glue between the deformable sheet 43 and the middle frame 11. Then, the injection-molded integral structural member 220 and the first and second pressure rods 41, 42, and other components are placed in the mounting groove and placed until the glue cures to form the elastic layer 53. The formed elastic layer 53 can fill the gap between the deformable sheet 43 and the middle frame 11.

[0148] The above description is based on the example that the elastic layer 53 can be silicone or rubber. In other embodiments of the present application, the elastic layer 53 can also be a tape or foam adhesive with a softer material.

[0149] Alternatively, in other embodiments of the present application, as shown in FIG17A , the elastic layer 53 may further include a soft gel layer 531 and a plurality of particles 532 doped in the soft gel layer 531 . The hardness of the particles 532 may be greater than the hardness of the soft gel layer 531 . The soft gel layer 531 may include silicone or rubber. The particles 532 may include metal particles, plastic particles, or rubber particles with relatively high hardness. Thus, as shown in FIG17B , under the pressure of the user (in the direction of the arrow), the soft gel layer 531 is elastically deformed under pressure, thereby reducing the spacing between the particles 532 . Furthermore, as shown in FIG17C , at least some of the particles 532 are in direct contact with each other, thereby increasing the rigidity of the entire elastic layer 53 and being able to support the deformable sheet 43 , achieving a limiting effect, so that the first cantilever end 431 and the second cantilever end 432 of the deformable sheet 43 are not easily plastically deformed.

[0150] As can be seen from the above, when a user presses the detection device 20, the first cantilever end 431 and the second cantilever end 432 of the deformable piece 43 shown in Figure 14B can deform downward along the Z direction. At this time, the pressure-sensitive element 44, which covers at least a portion of the first cantilever end 431 and at least a portion of the second cantilever end 432, can utilize the principle of piezoelectric induction to convert the deformation of the first cantilever end 431 and the second cantilever end 432 into an electrical signal, thereby detecting the user's pressing force. The following describes an example of the structure of the pressure-sensitive element 44 capable of implementing such piezoelectric induction.

[0151] In some embodiments of the present application, when the first circuit board 21 includes an FPC 2101 as shown in FIG18A , the pressure-sensitive element 44 can be connected to the FPC 2101 as an integral structure. During assembly of the detection device, the pressure-sensitive element 44 can be folded into a position stacked with the FPC 2101, as shown in FIG18B , so that the pressure-sensitive element 44 can be positioned on the side of the deformable sheet 43 facing the metal cover 24 in FIG16A .

[0152] Furthermore, the pressure-sensitive element 44 may include a resistance strain gauge, which may include a metal grid structure or a polymer ink structure. The principle of pressure sensing by the resistance strain gauge is that the resistance value of the metal grid structure or polymer ink structure in the resistance strain gauge is related not only to the properties of the material but also to dimensions such as the length and cross-sectional area of ​​the metal grid structure or polymer ink structure. The resistance strain gauge is attached to the deformation gauge 43, and when the deformation gauge 43 is deformed by force, the length and cross-sectional area of ​​the metal grid structure or polymer ink structure also change along with the deformation gauge 43, thereby causing the resistance value of the resistance strain gauge to change.

[0153] Based on this, as shown in FIG18A or FIG18B , the resistance strain gauge may include a first resistor R1, a second resistor R2, a fourth resistor R4, and a fifth resistor R5, wherein the first resistor R1, the second resistor R2, the fourth resistor R4, and the fifth resistor R5 are all variable resistors. Specifically, the portion of the pressure-sensitive element 44 covering the first cantilever end 431 shown in FIG16A includes the first resistor R1 and the second resistor R2, and the portion of the pressure-sensitive element 44 covering the second cantilever end 432 shown in FIG16A includes the fourth resistor R4 and the fifth resistor R5.

[0154] In this case, the detection device 20 may further include a third resistor R3 and a fourth resistor R4 as shown in FIG19A , wherein the third resistor R3 and the fourth resistor R4 are resistors with fixed resistances. For example, the third resistor R3 and the fourth resistor R4 may be arranged on the portion of the FPC 2101 in FIG16A that extends into the middle frame 11. Alternatively, for another example, the third resistor R3 and the fourth resistor R4 may be arranged on a mainboard located in the middle frame 11, such as the second circuit board 60 shown in FIG16A . This application does not limit the location of the third resistor R3 and the fourth resistor R4, as long as it can be ensured that the third resistor R3 and the fourth resistor R4 are not arranged on the pressure-sensitive element 44, so as to achieve the purpose of reducing the size of the pressure-sensitive element 44.

[0155] Based on this, as shown in FIG19A , the first resistor R1 and the second resistor R2 are connected in series to form a first circuit a1, and the third resistor R3 and the fourth resistor R4 are connected in series to form a second circuit a2. The first circuit a1 and the second circuit a2 can constitute a first full-bridge circuit 441 as shown in FIG19B . The first full-bridge circuit 441 can be electrically connected to the FPC 2101 (shown in FIG19A ) in the first circuit board via a first voltage terminal VDD, a second voltage terminal VCC, a first signal terminal S1+, and a second signal terminal S1-. The first voltage terminal VDD and the second voltage terminal VCC are power supply terminals for the first full-bridge circuit 441. The first voltage terminal VDD can provide an operating voltage to the first full-bridge circuit 441, and the second voltage terminal VCC can be grounded.

[0156] As shown in FIG16A , when a user presses the metal cover 24 of the detection device, the first cantilever end 431 of the deformable piece 43 is deformed. In this case, the resistance values ​​of the first resistor R1 and the second resistor R2 (as shown in FIG19B ) in the pressure-sensitive element 44 covering the first cantilever end 431 change, thereby changing the voltage difference between the first signal terminal S1+ and the second signal terminal S1-. This voltage difference matches the pressure applied by the user pressing the metal cover 24 (shown in FIG16A ). Therefore, the user's pressing pressure, such as the first pressure value, can be detected by obtaining this voltage difference.

[0157] Similarly, continuing with FIG19A , the fifth resistor R5 and the sixth resistor R6 are connected in series to form a third circuit a3, and the third resistor R3 and the fourth resistor R4 are connected in series to form the aforementioned second circuit a2. The aforementioned second circuit a2 and third circuit a3 can constitute a second full-bridge circuit 442 as shown in FIG19C . The second full-bridge circuit 442 can be electrically connected to the FPC 2101 (shown in FIG19A ) in the first circuit board via the first voltage terminal VDD, the second voltage terminal VCC, the third signal terminal S2+, and the fourth signal terminal S2-. As described above, the first voltage terminal VDD and the second voltage terminal VCC serve as power supply terminals for the second full-bridge circuit 442. The first voltage terminal VDD can provide an operating voltage to the second full-bridge circuit 442, and the second voltage terminal VCC can be grounded.

[0158] As shown in FIG16A , when a user presses the metal cover 24 of the detection device 20, the second cantilever end 432 of the deformable piece 43 is deformed. In this case, the resistance values ​​of the fifth resistor R5 and the sixth resistor R6 (as shown in FIG19C ) in the pressure-sensitive element 44 covering the second cantilever end 432 change, thereby changing the voltage difference between the third signal terminal S2+ and the fourth signal terminal S2-. This voltage difference matches the pressure applied by the user pressing the metal cover 24 (shown in FIG16A ). Therefore, the user's pressing pressure, such as the second pressure value, can be detected by obtaining this voltage difference.

[0159] As can be seen from the above, when a user presses the metal cover 24 of the detection device 20, the user's pressing pressure detected by the first full-bridge circuit 441 shown in FIG19B, for example, the first pressure value comes from the deformation of the first cantilever end 431 of the deformable piece 43 in FIG16A, and the user's pressing pressure detected by the second full-bridge circuit 442 shown in FIG19C, for example, the second pressure value comes from the deformation of the second cantilever end 432 of the deformable piece 43. The first cantilever end 431 and the second cantilever end 432 are respectively located on either side of the fixed end 430. Therefore, the processor of the electronic device 01 can determine whether the user's pressing position is in the middle of the metal cover 24 by comparing the difference between the first pressure value and the second pressure value, thereby improving detection accuracy. Therefore, the detection device 20 shown in FIG16A can be called a dual-channel detection structure.

[0160] For example, when the difference between the first and second pressure values ​​is large, the user's pressing position is biased toward the side with the larger pressure value. When the difference between the first and second pressure values ​​is small, the user's pressing position is located in the middle of the metal cover 24. This can promptly remind the user to change the pressing position so that the pressing position is in the middle of the metal cover 24, thereby achieving the purpose of improving detection accuracy.

[0161] On this basis, in order to enable the user to press to the preset position, a plurality of raised structures can be formed on the outer surface of the metal cover plate 24, and the user can clearly feel the concave and convex feeling of the touch surface during the pressing process. The position of the raised structure can match the preset pressing position, thereby guiding the user to press to the preset position and achieving the purpose of improving the detection accuracy.

[0162] In addition, in the above-mentioned dual-channel detection structure provided by the embodiment of the present application, as shown in FIG19A , only four variable resistors need to be set on the pressure-sensitive element 44, namely the first resistor R1, the second resistor R2, the fifth resistor R5, and the sixth resistor R6. Among them, the first full-bridge circuit 441 (shown in FIG19B ) composed of the first resistor R1, the second resistor R2, and the third resistor R3 and the fourth resistor R4 located outside the pressure-sensitive element 44 can share the third resistor R3 and the fourth resistor R4 with the second full-bridge circuit 442 composed of the fifth resistor R5, the sixth resistor R6, and the third resistor R3 and the fourth resistor R4 located outside the pressure-sensitive element 44. In this way, there is no need to directly set the eight variable resistors used to constitute the above-mentioned two full-bridge circuits on the pressure-sensitive element 44, thereby achieving the purpose of reducing the size of the pressure-sensitive element 44, which is conducive to reducing the size of the entire detection device 20 and even the size of the electronic device 01.

[0163] The above is an example of an example in which the detection device 20 shown in Figure 16A adopts a resistive pressure sensing method. In other embodiments of the present application, the detection device 20 can also adopt a capacitive pressure sensing method. In this case, as shown in Figure 16B, the detection device can also include a first metal electrode sheet 45 arranged on the side of the support plate 2102 away from the metal cover plate 24, and the first metal electrode sheet 45 can be electrically connected to the FPC2101. In addition, the pressure-sensitive element can include a second metal electrode sheet 46 in Figure 16B, and a capacitor can be formed between the first metal electrode sheet 45 and the second metal electrode sheet 46. In this way, when the user presses the metal cover plate 24 of the detection device 20, the spacing between the two metal electrodes changes, thereby changing the capacitance value of the capacitor, which matches the user's pressing pressure, thereby achieving the purpose of detecting the user's pressing pressure. Alternatively, in other embodiments, when the support plate 2102 includes a metal material, the support plate 2102 can serve as an electrode of a capacitor. In addition, the pressure-sensitive element 44 can be made of metal material to serve as another electrode of the above-mentioned capacitor, thereby realizing the above-mentioned capacitive pressure sensing method.

[0164] Alternatively, in other embodiments of the present application, the detection device 20 can also adopt an inductive pressure sensing method. In this case, the support plate 2102 shown in Figure 16A can be made of metal material, and the above-mentioned pressure sensitive element 44 can include a coil. In this case, an electric current can be passed through the coil. When the user presses the metal cover 24 of the detection device 20, the distance between the support plate 2102 and the pressure sensitive element 44 changes, thereby changing the magnetic field generated by the coil and changing the impedance of the coil. The above-mentioned impedance can match the pressure of the user to achieve the purpose of detecting the pressure of the user. Alternatively, in other embodiments, the detection device can also include a metal electrode sheet arranged on the side of the support plate 2102 away from the metal cover 24, and the above-mentioned pressure sensitive element 44 can include a coil, in order to achieve the above-mentioned inductive pressure sensing method.

[0165] As can be seen from the above, the detection device 20 with a pressure-sensing function shown in Figure 16A is illustrated by taking the case where the pressure-sensitive element 44 in the detection device 20 is arranged on the outside of the middle frame 11, and the detection device is a dual-channel detection structure. In other embodiments of the present application, the pressure-sensitive element 44 of the detection device 20 can be arranged inside the middle frame 11. Specifically, as shown in Figure 20 (a cross-sectional view obtained by cutting along the dotted line O1-O2 in Figure 2B), the detection device 20 includes the above-mentioned first circuit board 21, the light-emitting device 22, the photoelectric converter 23, the metal cover plate 24, the first pressure rod 41, the second pressure rod 42, the deformation piece 43 and the pressure-sensitive element 44, etc. Among them, the first circuit board 21 can be a PCB. The setting method and working process of the light-emitting device 22, the photoelectric converter 23 and the metal cover plate 24 are the same as described above and will not be repeated here.

[0166] In the embodiment of the present application, the middle frame 11 is an annular structure having a hollow area, and can be a circular ring or a rectangular ring. The outside of the middle frame 11 or the outer side of the middle frame 11 refers to the side of the middle frame 11 away from the hollow area, and the inside of the middle frame 11 or the inner side of the middle frame 11 refers to the side of the middle frame 11 facing the hollow area.

[0167] In addition, as shown in Figure 20, the deformable piece 43 is located in the middle frame 11, and the deformable piece 43 is arranged on the side of the first pressure rod 41 and the second pressure rod 42 facing away from the first circuit board 21. The deformable piece 43 has a first cantilever end 431, a second cantilever end 432, and a fixed end 430 located between the first cantilever end 431 and the second cantilever end 432. The first pressure rod 41 passes through the first mounting hole 301. The first pressure rod 41 is arranged on the side of the first circuit board 21 facing away from the metal cover 24. The first end (for example, the upper end) of the first pressure rod 41 abuts or is connected to the first circuit board 21, and the second end (for example, the lower end) of the first pressure rod 41 extends out of the first mounting hole 301 and is located in the middle frame 11, and abuts or is connected to the first cantilever end 431 of the deformable piece 43. Furthermore, a second pressure rod 42 extends through the second mounting hole 302 and is positioned on a side of the first circuit board 21 facing away from the metal cover 24. A first end (e.g., the upper end) of the second pressure rod 42 abuts or connects with the first circuit board 21, while a second end (e.g., the lower end) of the second pressure rod 42 extends out of the second mounting hole 302, is positioned within the middle frame 11, and abuts or connects with the second cantilever end 432. The manner in which the first and second pressure rods 41, 42 are secured to the middle frame 11 via the retaining rings, and the manner in which they are sealed to the middle frame 11 via the sealing rings, are similar to those described above and will not be further elaborated here.

[0168] On this basis, to secure the fixed end 430 of the deformable piece 43, the electronic device may further include a threaded connector 61 as shown in FIG20 . The threaded connector 61 may be a bolt or a screw. The threaded connector 61 may be located within the middle frame 11 , passing through the fixed end 430 of the deformable piece 43 and connected to the middle frame 11 to secure the deformable piece 43 to the middle frame 11.

[0169] In addition, the pressure-sensitive element 44 is located in the middle frame 11. The pressure-sensitive element 44 is arranged on the side of the deformable piece 43 away from the metal cover plate 24, and the pressure-sensitive element 44 covers at least a portion of the first cantilever end 431 and at least a portion of the second cantilever end 432. The pressure-sensitive element 44 can be electrically connected to the first circuit board 21. Among them, in the pressure-sensitive element 44, the part covering the first cantilever end 431 and the part covering the second cantilever end 432 can be connected as an integral structure, or can be disconnected and independently arranged separately. This application does not limit this. In addition, the setting method and working process of the pressure-sensitive element 44 are the same as described above and will not be repeated here. In this embodiment, since the pressure-sensitive element 44 is arranged in the middle frame 11, the influence of external water vapor or impurities on the pressure-sensitive element 44 can be reduced, which is conducive to improving the accuracy of pressure detection.

[0170] On this basis, to facilitate the return of the deformed deformable sheet 43 to its initial position after the user releases the pressure applied to the metal cover 24, the electronic device may further include a first spring 71 and a second spring 72 as shown in FIG20 . The first spring 71 is positioned within the mounting groove 300, a portion of the first pressure rod 41 passes through the first spring 71, and the two ends of the first spring 71 respectively abut against the first pressure rod 41 and the bottom of the mounting groove 300. Furthermore, the second spring 72 is positioned within the mounting groove 300, a portion of the second pressure rod 42 passes through the second spring 72, and the two ends of the second spring 72 respectively abut against the second pressure rod 42 and the bottom of the mounting groove 300. Based on this, to ensure that the first pressure rod 41 abuts the first spring 71, the end of the first pressure rod 41 abutting the first spring 71 can be configured as a step. Similarly, to ensure that the second pressure rod 42 abuts the second spring 72, the end of the second pressure rod 42 abutting the second spring 72 can be configured as a step. When the user does not press the detection device 20, the first spring 71 and the second spring 72 can be in a compressed state. Therefore, by adjusting the distance between the step-like structure and the bottom of the installation groove 300, the compression amount of the first spring 71 and the second spring 72 can be adjusted.

[0171] In addition, as shown in Figure 21 (a cross-sectional view obtained by cutting along the dotted line C1-C2 in Figure 2B), the electronic device may further include an FPC, one end of which can be electrically connected to the first circuit board 21 located in the mounting groove 300, and the other end of the FPC can pass through the plug 54 and the second adhesive layer 55 to extend into the middle frame 11, so that it can be electrically connected to the mainboard in the middle frame 11.

[0172] As can be seen from the above, the detection device 20 shown in Figure 16A and Figure 20 are both examples of the detection device 20 being a dual-channel detection structure. In other embodiments of the present application, as shown in Figure 22 (a cross-sectional view obtained by cutting along the dotted line O1-O2 in Figure 2B), the detection device 20 can also be a single-channel detection structure, and the pressure-sensitive element 44 is arranged in the middle frame 11. Specifically, the detection device 20 includes the above-mentioned first circuit board 21, the light-emitting device 22, the photoelectric converter 23, the metal cover plate 24, the first pressure rod 41, the deformation piece 43 and the pressure-sensitive element 44, etc. Among them, the first circuit board 21 can be an FPC. The setting method and working process of the light-emitting device 22, the photoelectric converter 23 and the metal cover plate 24 are the same as described above and will not be repeated here.

[0173] Based on this, as shown in Figure 22, a first mounting hole 301 that passes through the middle frame 11 is provided at the bottom of the mounting groove 300. A first pressure rod 41 passes through the first mounting hole 301. The first pressure rod 41 is arranged on the side of the first circuit board facing away from the metal cover plate 24. The first end of the first pressure rod 41 abuts or is connected to the first circuit board 21. The deformable sheet 43 is located in the middle frame 11, and the deformable sheet 43 is arranged on the side of the first pressure rod 41 facing away from the first circuit board 21. The deformable sheet 43 has a first cantilever end 431 and a fixed end 430. The first cantilever end 431 abuts the second end of the first pressure rod 41, and the fixed end 430 of the deformable sheet 43 is connected to the middle frame 11. For example, a mounting hole can be provided on the inner wall of the middle frame 11, and the fixed end 430 of the deformable sheet 43 can be embedded in the above-mentioned mounting hole and bonded to the middle frame 11 through the adhesive layer. Alternatively, a threaded connector may be used, which passes through the fixed end 430 of the deformable piece 43 and is connected to the middle frame 11 to fix the fixed end 430 of the deformable piece 43 to the middle frame 11 .

[0174] In addition, the pressure-sensitive element 44 is located in the middle frame 11 and is arranged on the side of the deformable piece 43 away from the metal cover plate 24, and the pressure-sensitive element 44 can cover at least a portion of the first cantilever end 431 of the deformable piece 43. As mentioned above, the pressure-sensitive element 44 is electrically connected to the first circuit board 21. The setting method and working process of the pressure-sensitive element 44 are the same as those described above and will not be repeated here. Moreover, the technical effect of setting the pressure-sensitive element 44 in the middle frame 11 is the same as those described above and will not be repeated here. Based on this, the deformable piece 43 in the structure shown in Figure 22 has only one cantilever end, namely the first cantilever end 431, so the size of the deformable piece 43 can be reduced, which is conducive to simplifying the size of the entire detection device 20.

[0175] On this basis, for example, the electronic device may include a first adhesive layer 56 and a second snap ring 57, the first adhesive layer 56 being arranged between the first circuit board 21 and the bottom of the mounting groove 300, and the first adhesive layer 56 can be connected to the first circuit board 21 and the bottom of the mounting groove 300. The above-mentioned first adhesive layer 56 can be a glue layer, so that the first circuit board 21 and the various components arranged on the first circuit board 21 can be fixed on the middle frame 11. In addition, the second snap ring 57 is located in the middle frame 11, and the second snap ring 57 is clamped to the second end of the first pressure rod 41, and the second snap ring 57 is in contact with the middle frame 11. In this way, when the user presses the detection device 20, the movement of the first pressure rod 41 along the Y direction can be limited by the above-mentioned second snap ring 57.

[0176] In other embodiments of the present application, when the detection device 20 adopts the structure of Figure 22, by changing the structure of the cantilever end of the deformable sheet 43, the detection device can also be made into a dual-channel detection structure. Specifically, as shown in Figure 23A, the deformable sheet 43 may include two cantilever ends, namely a first cantilever end 431 and a second cantilever end 432, and the second cantilever end 432 is located on the side of the first cantilever end 431 away from the fixed end 430, and there is a gap H between the first cantilever end 431 and the second cantilever end 432. The pressure-sensitive element 44 (as shown in Figure 22) covers at least a portion of the first cantilever end 431 and also covers at least a portion of the second cantilever end 432. In addition, as shown in Figure 23B, the second end (for example, the lower end) of the first pressure rod 41 can be simultaneously abutted or connected to the first cantilever end 431 and the second cantilever end 432. In this way, by setting up a pressure rod, that is, the first pressure rod 41 can press the first cantilever end 431 and the second cantilever end 432 at the same time, thereby driving the first cantilever end 431 and the second cantilever end 432 to deform at the same time, thereby achieving the purpose of dual-channel pressure detection.

[0177] In summary, as shown in Figure 24, the detection device 20 in the electronic device 01 provided in the embodiment of the present application may include a PPG module, an ECG electrode and a pressure sensing module. Among them, the PPG module (including the light-emitting device 22 and the photoelectric converter 23 shown in Figure 16A) can obtain PPG data such as the user's blood oxygen and heart rate. ECG electrodes, such as the metal cover 24, or the metal cover 24 and the metal plating 241 can obtain ECG data. The pressure sensing module includes components such as a first pressure rod 41, a deformable sheet 43, a pressure-sensitive element 44, etc., for detecting the user's pressing pressure. The above-mentioned pressure sensing module can be the above-mentioned resistive, capacitive or inductive. Continuing with Figure 24, the processor in the electronic device 01 can calculate the user's blood pressure value by combining the PPG data, ECG data and the detected pressure value, and then display the above-mentioned blood pressure, blood oxygen and heart rate information through the display.

[0178] On this basis, in some embodiments of the present application, the detection device 20 can also function as a virtual button. For example, when a user presses the detection device 20, the processor can obtain the user's pressing pressure through the pressure sensing module and control the vibration motor to vibrate. The vibration intensity can match the user's pressing pressure, thereby allowing the user to perceive the pressing experience. In addition, the processor can also control the electronic device 01 to activate the corresponding button function to realize the function of the virtual button.

[0179] Alternatively, in other embodiments of the present application, the detection device 20 may also function as part of a physical button. In this case, the electronic device may further include a pot connected to the pressure-sensing module in the detection device 20. When a user presses the detection device 20, the pot may be deformed, thereby executing the button function.

[0180] The above description is based on an example in which the pressure sensing module is integrated into the detection device 20. In other embodiments of the present application, the detection device 20 having the PPG module and ECG electrodes can be provided separately from the pressure sensing module. In this case, the detection device 20 may not have a button function.

[0181] The following describes an example of a detection device 20 having a key function and a health detection function to illustrate a control method of an electronic device 01 having the detection device 20. Specifically, the control method of the electronic device 01 is shown in FIG25 and may include S101 to S114.

[0182] S101 , scanning a pressure-sensitive element at a first scanning frequency.

[0183] For example, by executing the above S101, a user pressing event on the detection device 20 can be identified. In addition, the pressure sensitive element 44 in the pressure sensing module 400 is scanned using a first scanning frequency f1 with a relatively low frequency, so that the pressure sensing module 400 operates at a relatively low first power consumption, thereby achieving the purpose of reducing power consumption.

[0184] S102: Determine whether the health detection function is enabled.

[0185] For example, as shown in FIG26 , a health detection function button 80 may be displayed on the display screen of the electronic device 01, and the user can turn on or off the health detection function by touching the health detection function button 80 on the display screen. The above-mentioned health detection function may include detecting data such as the user's blood oxygen, heart rate or blood pressure. Therefore, to determine whether the health detection function is turned on, specifically the start-up operation of the light emitting device 22 function and the start-up operation of the photoelectric converter 23 function in the detection device 20. When the health detection function is turned on, the processor can detect the start-up operation of the light emitting device 22 function and the start-up operation of the photoelectric converter 23 function. When the health detection function is turned off, the processor cannot detect the start-up operation of the light emitting device 22 function and the start-up operation of the photoelectric converter 23 function.

[0186] Based on this, when the judgment result of S102 shown in Figure 25 is "No", that is, the above-mentioned health detection function is in the off state, the following S111 to S114 can be executed to execute the key function. Alternatively, when the judgment result of S102 is "Yes", that is, the above-mentioned health detection function is in the on state, the following S103 to S108 can be executed to execute the health detection function.

[0187] S103: Display a guidance image.

[0188] In some embodiments of the present application, the electronic device 01 may display a guidance image, which is used to display a guidance message during the execution of the health check function to prompt the user to complete the health check. For example, when starting the health check, a prompt message such as "Please press your finger directly to the button position" as shown in Figure 27 may be displayed. During the health check process, the above guidance image can be adjusted according to the content of the guidance required, and this application does not limit the content of the guidance image.

[0189] S104: Determine whether the user's body (eg, finger) directly presses the detection device.

[0190] For example, in some embodiments, since the health detection function has been turned on, when the user's finger directly presses the detection device 20, the light-emitting device 22 in the detection device 20 shown in Figure 16A emits infrared light, and the infrared light can be used to achieve infrared proximity detection. Since infrared light can be absorbed by hemoglobin and deoxyhemoglobin in the blood, the PPG data can be obtained to determine whether the user's finger directly presses the detection device 20.

[0191] Alternatively, in other embodiments, a voltage may be applied to the metal cover plate 24 so that the metal cover plate 24 functions as an ECG electrode. When the user's finger presses the detection device 20, the impedance change in the path formed by the ECG electrode and the human body may be obtained to determine whether the user's finger is directly pressing the detection device 20. Based on this, when the judgment result of S104 is "yes", the following S105 may be executed. When the judgment result of S104 is "no", S103 may be executed to display the guidance image shown in Figure 27.

[0192] S105 , scanning the pressure-sensitive element at a second frequency to obtain a pressure value F, driving the PPG module, and driving the ECG electrodes to obtain an electrocardiogram signal.

[0193] For example, the processor may use a higher second scanning frequency f2 (where f2>f1) to scan the pressure sensitive element 44 in the pressure sensing module 400, so that the pressure sensing module 400 operates at a higher second power consumption (where the second power consumption is greater than the first power consumption), thereby obtaining the pressure value F applied by the user to the metal cover 24. The pressure sensing module 400 in the detection device 20 (as shown in FIG13 ) may utilize the aforementioned resistive, capacitive, or inductive pressure sensing detection principles.

[0194] In addition, the processor can drive all light-emitting elements (including visible light-emitting elements and infrared light-emitting elements) in the light-emitting device 22 in the detection device 20 and the photoelectric converter 23 to operate to activate the PPG module, thereby obtaining the user's PPG data (including blood oxygen data and heart rate data) by obtaining the output signal of the photoelectric converter 23. In addition, the processor can also apply voltage to the metal cover 24 to drive the metal cover 24 as an ECG electrode to obtain electrocardiographic signals.

[0195] S106. Determine whether F1≤F≤F2.

[0196] For example, during the execution of S106 shown in FIG. 25 , if the pressure value F obtained in S102 is greater than or equal to the first threshold F1 and less than or equal to the second threshold F2, the processor may execute S107 below. The second threshold F2 is greater than the first threshold F1. For example, F1 = 10 gf and F2 = 300 gf.

[0197] S107: Data calculation. For example, the above S108 may include S201 to S203 as shown in FIG28 .

[0198] S201 , collecting PPG data, ECG data, and pressure data for a certain period of time.

[0199] For example, in order to improve the accuracy of calculating blood pressure, the processor can continuously collect the above-mentioned PPG data, ECG data and pressure data within a certain period of time.

[0200] S202: Determine in real time whether the collected PPG data, ECG data, and pressure data meet preset requirements.

[0201] For example, the processor can compare the collected PPG data, ECG data, and pressure data with preset requirements, such as data accuracy and data duration, in real time. If the judgment result of S202 is "yes", that is, the above data meets the preset requirements, then S203 shown in Figure 25 is executed. If the judgment result of S202 is "no", that is, the above data does not meet the preset requirements, for example, the user's finger is not in a pressing state, then the prompt dialog box 81 shown in Figure 29 can be displayed to prompt the user to press the detection device 20 again. After the user presses the detection device again, S105 shown in Figure 25 can be executed to re-obtain the pressure value F.

[0202] S203: Call an algorithm to calculate a value. For example, the processor may call a related algorithm from the memory and determine a detection result based on at least one of the pressure value, the output signal of the photoelectric converter, and the electrocardiogram signal obtained in S107 shown in FIG25 . The detection result may include at least one of a blood oxygen value, a heart rate value, electrocardiogram data, and a blood pressure value.

[0203] S108. Display at least one of blood oxygen, heart rate, and blood pressure.

[0204] As shown in FIG30 , electronic device 01 can display test results, including at least one of the aforementioned blood oxygen, heart rate, and blood pressure data. Furthermore, these blood oxygen, heart rate, and blood pressure data can change in real time based on the user's pressure. When the user's pressure reaches the middle position of pressure scale 70, the displayed blood oxygen, heart rate, and blood pressure data serve as the final test data.

[0205] Among them, the arrow in the pressure scale 70 can move on the scale following the size of the user's pressing force. The different colored stages on the pressure scale 70 can indicate the size of the user's pressing force. Alternatively, in other embodiments, one side of the pressure scale 70 can also display the size of the pressure value F, for example, 200gf. In this way, it can be guided that the pressure value applied when the user presses can be within a preset range, such as (10gf~300gf), and this range can correspond to the position of the middle stage of the pressure scale 70, thereby achieving the purpose of improving the detection accuracy. Alternatively, when the above-mentioned detection device 20 has a dual-channel pressure sensing detection function, the electronic device 01 can also display a pressing position prompt image based on the results of the dual-channel pressure sensing detection to prompt the user to press to the preset position, thereby achieving the purpose of improving the detection accuracy.

[0206] S109, end.

[0207] In addition, it can be seen from the above that when the judgment result of S102 shown in Figure 25 is "No", that is, when the above health detection function is in the off state, the following S111 to S114 can be executed to execute the key function.

[0208] S111 , after the pressure-sensitive element detects a signal, the pressure-sensitive element is scanned at a second scanning frequency to obtain a pressure value F.

[0209] The signal detected by the pressure-sensitive element 44 is a pressure signal generated when the user presses the metal cover 24 of the detection device 20 .

[0210] S112. Determine whether F≥F3.

[0211] For example, if the pressure value F obtained in S112 is greater than or equal to the third threshold value F3, S113 is executed. The third threshold value F3 may be in the range of 10 gf to 300 gf. If the judgment result of S112 is "No", the above S111 is executed to re-acquire the pressure value F.

[0212] S113: Determine whether the user performs a touch operation.

[0213] For example, in order to avoid the detection device 20 being mistakenly triggered due to "non-user triggering reasons" when the user is using the electronic device, for example, a "temperature conflict" caused by a sudden sudden change in the ambient temperature of the electronic device, in some embodiments of the present application, before executing S114, S113 can be executed to determine whether the pressing force of the detection device 20 comes from the user's touch operation. Specifically, when the light-emitting device 22 in the detection device 20 shown in Figure 16A is capable of emitting infrared light, the infrared light can be used to achieve infrared proximity detection. If the user's touch operation on the metal cover 24 is detected, the above S114 can be executed. If the user's touch operation on the metal cover 24 is not detected, S109 can be executed. In other embodiments of the present application, S113 may not be required in the above control method.

[0214] S114: Execute key function.

[0215] For example, during the execution of S114, if the detection device 20 is a virtual button, the processor can control the vibration motor shown in FIG24 to operate and perform the button function. Alternatively, if the detection device 20 is a physical button, the detection device 20 can drive the pot piece to deform and perform the button function.

[0216] After executing the above S114, S109 may be executed to end the above control method.

[0217] To sum up, the control method of the electronic device 01 provided in the embodiment of the present application can realize both health data detection and key response function, so that health detection and key can be integrated into the same detection device 20, thereby achieving the purpose of improving the integration of the electronic device 01 and reducing the size of the electronic device 01.

[0218] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
