[0003] When a smartwatch is worn on a user's wrist, the light-emitting diode (LED) illuminates the skin and blood vessels, generating a light signal. The photodiode receives this light signal reflected from the user's skin and converts it into an electrical signal. This electrical signal is then used by the PPG module to detect the user's health characteristics, such as heart rate, respiratory rate, and blood oxygen saturation. Currently, the back of the watch not only has a light-transmitting lens for the light signal to pass through but also a stainless steel temperature-sensing probe for temperature measurement, thus occupying a relatively large space.

[0027] With the continuous development of electronic devices such as smartwatches, smartwatches generally have the function of detecting vital signs, such as detecting the user's heart rate, respiratory rate, blood oxygen and other physiological information through photoplethysmography (PPG) and electrocardiogram (ECG).

[0028] When a smartwatch is worn on a user's wrist, the light-emitting diode (LED) illuminates the skin and blood vessels, generating a light signal. The photodiode receives this light signal reflected from the user's skin and converts it into an electrical signal. This electrical signal is then used by the PPG module to detect the user's health characteristics, such as heart rate, respiratory rate, and blood oxygen saturation. Currently, the back of the watch not only has a light-transmitting lens for the light signal to pass through but also a stainless steel temperature-sensing probe for temperature measurement, thus occupying a relatively large space.

[0029] To alleviate or solve the above-mentioned technical problems, this utility model proposes a cover structure 10 for an electronic device and the electronic device itself. The cover structure 10 includes a cover body 11 and an electrode layer 12. The electrode layer 12 extends from the front to the back of the cover body 11, and a temperature-sensing electrode 125 is formed on the back of the cover body 11. When the electronic device is in use, the cover structure 10 is in contact with the skin, and health indicators such as heart rate, respiratory rate, and blood oxygen can be detected through the positive electrode layer 121 and the negative electrode layer 122. Temperature can also be transmitted to the temperature-sensing module 40 through the temperature-sensing electrode 125 for temperature detection. In this way, the electrodes required for temperature detection and health indicator detection are integrated into the cover structure 10, occupying less space and saving space.

[0030] The cover structure 10 of the electronic device provided in the present invention will now be described.

[0031] Please refer to the following: Figures 1 to 3 The cover structure 10 of the electronic device includes a cover body 11 and an electrode layer 12. The cover body 11 has a front side for contact with the skin and a back side opposite to the front side. The electrode layer 12 covers the front side and extends to the back side. The electrode layer 12 includes a positive electrode layer 121 and a negative electrode layer 122 spaced apart from each other, and the back side is covered with an insulating layer 13. The insulating layer 13 has a first window 131 that exposes part of the positive electrode layer 121, a second window 132 that exposes part of the negative electrode layer 122, and a third window 133 that exposes part of the negative electrode layer 122. A temperature sensing electrode 125 is formed at the third window 133.

[0032] The cover plate body 11 is the main structure of the cover plate structure 10, and the electrode layer 12, insulating layer 13, etc., are all structures covering the cover plate body 11. The cover plate body 11 is generally a plate-shaped, thin-walled structure. The cover plate body 11 covers the vital sign detection module 30 and the temperature sensing module 40, and transmits information such as pulse and temperature to the corresponding modules through direct contact with the skin. The cover plate body 11 has a front and a back side that are arranged opposite to each other. The front side is used for contact with the skin, that is, the exposed surface of the cover plate structure 10, and the back side of the cover plate body 11 is arranged facing the interior of the electronic device, and can be arranged towards the vital sign detection module 30 and the temperature sensing module 40.

[0033] The electrode layer 12 is a conductive structure and can be made of conductive metallic materials such as copper or aluminum. The electrode layer 12 covers the front side of the cover plate body 11 and extends to the back side, meaning that the electrode layers 12 on the front and back sides of the cover plate body 11 are interconnected. The electrode layer 12 includes a positive electrode layer 121 and a negative electrode layer 122 spaced apart from each other, ensuring that the positive electrode layer 121 and the negative electrode layer 122 are mutually insulated.

[0034] An insulating layer 13 covers the back side of the cover plate structure 10 and also covers the electrode layer 12 on the back side. The insulating layer 13 has a first window 131, a second window 132 and a third window 133. The first window 131 exposes part of the positive electrode layer 121 to form a positive electrode contact 123. The second window 132 exposes part of the negative electrode layer 122 to form a negative electrode contact 124. The third window 133 exposes part of the negative electrode layer 122 to form a temperature sensing electrode 125.

[0035] When the cover structure 10 is installed on the host, the positive contact 123 and the negative contact 124 are in contact with the vital signs detection module 30, and the temperature sensing electrode 125 is in contact with the temperature sensing module 40.

[0036] The cover structure 10 of the electronic device in the above embodiment includes a cover body 11 and an electrode layer 12. The electrode layer 12 extends from the front to the back of the cover body 11 and includes a positive electrode layer 121 and a negative electrode layer 122 spaced apart. By covering the back of the cover body 11 with an insulating layer 13, a positive electrode contact 123, a negative electrode contact 124, and a temperature-sensing electrode 125 are formed on the back of the cover body 11. The positive electrode contact 123 and the negative electrode contact 124 can be connected to the vital sign detection module 30 in the host, and the temperature-sensing electrode 125 can be connected to the temperature-sensing module 40 in the host. When the front of the cover body 11 is in contact with the skin, the vital sign detection module 30 can detect physiological information such as heart rate, respiratory rate, and blood oxygenation. At the same time, the skin temperature is transmitted to the temperature-sensing electrode 125, and the temperature-sensing module 40 detects the skin surface temperature. The temperature-sensing electrode 125 and the positive and negative electrodes are integrated into the cover structure 10, which can reduce space occupation.

[0037] Please refer to some embodiments of this utility model. Figure 2 The first window 131, the second window 132, and the third window 133 are all square. In other embodiments, the first window 131, the second window 132, and the third window 133 may also be circular or other shapes. In other embodiments, the first window 131, the second window 132, and the third window 133 may also be located close to the gap between the positive electrode layer 121 and the negative electrode layer 122, and one side of the window may be the edge of the gap.

[0038] Please refer to some embodiments of this utility model. Figure 1 and Figure 2 The positive electrode layer 121 includes a first positive electrode layer 1211 covering the front side, a second positive electrode layer covering the back side, and a first connecting layer that connects the first positive electrode layer 1211 and the second positive electrode layer. The negative electrode layer 122 includes a first negative electrode layer 1221 covering the front side, a second negative electrode layer covering the back side, and a second connecting layer that connects the first negative electrode layer 1221 and the second negative electrode layer. An insulating layer 13 covers the second positive electrode layer and the second negative electrode layer. In the positive electrode layer 121, the first positive electrode layer 1211, the second positive electrode layer, and the first connecting layer are all interconnected, and the first connecting layer is located on the sidewall of the cover structure 10 (the sidewall connects the front and back sides). In the negative electrode layer 122, the first negative electrode layer 1221, the second negative electrode layer, and the second connecting layer are all interconnected, and the second connecting layer is located on the sidewall of the connecting structure. Understandably, the first positive electrode layer 1211 and the first negative electrode layer 1221 are spaced apart from each other, the second positive electrode layer and the second negative electrode layer are spaced apart from each other, and the first connecting layer and the second connecting layer are spaced apart from each other.

[0039] The back of the cover plate body 11 has a second positive electrode layer and a second negative electrode layer. An insulating layer 13 covers the second positive electrode layer and the second negative electrode layer, thereby forming a positive electrode contact 123, a negative electrode contact 124 and a temperature sensing electrode 125.

[0040] In some embodiments, the cover plate body 11 is divided into two regions in its length or width direction, with the positive electrode layer 121 and the negative electrode layer 122 located in the two regions respectively, and a strip-shaped gap formed between the positive electrode layer 121 and the negative electrode layer 122. This makes the structure of the positive electrode layer 121 and the negative electrode layer 122 simpler and easier to process.

[0041] In some embodiments of this utility model, the electrode layer 12 is covered on the cover plate body 11 by electroplating.

[0042] In some embodiments of this utility model, the insulating layer 13 is a screen-printed insulating layer, that is, the insulating layer 13 is covered on the back of the cover plate body 11 by screen printing. Screen printing is a relatively strong method, and the processing technology is also relatively mature, resulting in lower production costs.

[0043] In other embodiments, the insulating layer 13 may also be applied to the back of the cover plate body 11 by means of spraying or other methods. The insulating layer 13 may also be an insulating film, which is directly attached to the back of the cover plate body 11.

[0044] In some embodiments, the insulating layer 13 has the same shape and size as the second positive electrode layer and the second negative electrode layer, and the insulating layer 13 is completely overlapped with the second positive electrode layer and the second negative electrode layer. The second positive electrode layer and the second negative electrode layer are separated from each other, and correspondingly, the insulating layer 13 includes two separate insulating units.

[0045] Please refer to some embodiments of this utility model. Figure 2 and Figure 3 The cover plate structure 10 also includes a cover film 14. The area of ​​the cover plate body 11 not covered by the electrode layer 12 is a light-transmitting area. The cover film 14 covers the back side and faces the light-transmitting area. The cover film 14 has Fresnel patterns. The cover film 14 is fixed to the back side of the cover plate body 11. The area covered by the cover film 14 does not have the electrode layer 12 and the insulating layer 13, allowing light to pass through the cover film 14 and the cover plate body 11. A Fresnel pattern is a special type of optical lens whose surface is composed of a series of continuous, concentric rings. Each ring can be considered as a small convex or concave lens.

[0046] By setting a cover film 14 with Fresnel patterns, efficient focusing can be achieved, as well as a large field of view, thereby detecting a larger area.

[0047] In some embodiments, the cover film 14 is circular, which facilitates the design of Fresnel patterns.

[0048] In some embodiments of this invention, the positive electrode layer 121 and the negative electrode layer 122 are spaced apart, and the positive electrode layer 121 has a first notch on the side near the negative electrode layer 122, while the negative electrode layer 122 has a second notch on the side near the positive electrode layer 121. The first and second notches together form a circular light-transmitting area. The first and second notches are formed in the gap between the positive electrode layer 121 and the negative electrode layer 122, which together form the light-transmitting area.

[0049] By setting a first notch and a second notch on the positive electrode layer 121 and the negative electrode layer 122 respectively, a light-transmitting area is formed. In this way, the remaining space of the light-transmitting body is fully utilized, and the electrode layer 12 is completely covered except for the light-transmitting area. This can increase the area of ​​the electrode layer 12, thereby improving the thermal conductivity and electrical conductivity.

[0050] In some embodiments, both the first notch and the second notch are semicircular, making the structures of the positive electrode layer 121 and the negative electrode layer 122 symmetrical and the conductivity more stable.

[0051] In some embodiments, the light-transmitting area is located in the middle of the lens body, making the lens structure symmetrical and easier to process and shape.

[0052] In some embodiments of this utility model, the cover film 14 includes a first light-transmitting area 141, a first light-blocking area 142, a second light-transmitting area 143, and a second light-blocking area 144 arranged sequentially from the inside out. Both the first light-transmitting area 141 and the second light-transmitting area 143 are provided with Fresnel patterns. The first light-transmitting area 141 is circular, while the first light-blocking area 142, the second light-transmitting area 143, and the second light-blocking area 144 are all annular structures. The first light-blocking area 142 is disposed between the first light-transmitting area 141 and the second light-transmitting area 143, isolating the two light-transmitting areas and preventing mutual interference between the light from the two areas, ultimately affecting the detection results. The second light-blocking area 144 is disposed on the outer periphery of the second light-transmitting area 143, preventing light leakage from the second light-transmitting area 143.

[0053] By setting the first light-blocking area 142, the two light-transmitting areas can be isolated, preventing the light from the two light-transmitting areas from affecting each other and ultimately affecting the test results. By setting the second light-blocking area 144, light leakage from the second light-transmitting area 143 can be prevented, thus preventing it from affecting the test and appearance.

[0054] In some embodiments, the first shading area 142 and the second shading area 144 may be black, and black has a better shading effect.

[0055] Optionally, the first light-shielding area 142 and the second light-shielding area 144 are coated with black ink to form light-shielding areas.

[0056] In some embodiments of this utility model, the first light-transmitting area 141 allows emitted light to pass through, and the second light-transmitting area 143 allows received light to pass through. Specifically, when the light-transmitting structure is installed on the host, the first light-transmitting area 141 faces the light emitter 31, and the second light-transmitting area 143 faces the light receiver 32. The light emitter 31 passes through the first light-transmitting area 141 to the skin tissue and blood vessels, and after being reflected by the skin, it passes through the second light-transmitting area 143, is received by the light receiver 32, and is converted into an electrical signal. The vital signs detection module 30 analyzes the electrical signal to obtain the user's health characteristics such as heart rate, respiratory rate, and blood oxygen.

[0057] The first light-transmitting area 141 allows emitted light to pass through, and the second light-transmitting area 143 allows received light to pass through. The second light-transmitting area 143 is located on the outer periphery of the first light-transmitting area 141. The second light-transmitting area 143 has a larger area, which allows for the placement of more light receivers 32, thereby obtaining more reflected signals and improving the accuracy of the detection results.

[0058] In other embodiments, the first light-transmitting area 141 is for receiving light to pass through, and the second light-transmitting area 143 is for emitting light to pass through.

[0059] Please refer to some embodiments of this utility model. Figures 1 to 3 The cover plate body 11 is a glass cover plate. The cover plate body 11 is made of glass, which has high clarity and is not easily scratched. When light is emitted or incident, the light emissivity and incidentivity are high, which can improve the detection effect.

[0060] The cover plate body 11 is conventionally made of plastic. Plastic covers have low clarity and are prone to wear, which affects the light transmission effect. Therefore, designing the cover plate body 11 to be made of glass can improve the light emissivity and incident frequency, thereby improving the detection effect.

[0061] In some embodiments of this invention, the electrode layer 12 is a copper electrode layer, which has good conductivity. In other embodiments, the electrode layer 12 may also be a silver electrode layer, an alloy electrode layer, etc.

[0062] Please see Figure 4 This utility model also provides an electronic device, which includes the cover structure 10 in any of the above embodiments, and also includes a housing structure 20, with the cover structure 10 fixed to the housing structure 20. After the housing structure 20 and the cover structure 10 are fixed to each other, an internal space is formed, which can accommodate circuit boards, modules, and other structures.

[0063] The electronic device provided by this utility model adopts the aforementioned cover plate structure 10. The cover plate structure 10 includes a cover plate body 11 and an electrode layer 12. The electrode layer 12 extends from the front side of the cover plate body 11 to its back side, and includes a positive electrode layer 121 and a negative electrode layer 122 spaced apart. By covering the back side of the cover plate body 11 with an insulating layer 13, a positive electrode contact 123, a negative electrode contact 124, and a temperature-sensing electrode 125 are formed on the back side of the cover plate body 11. The positive electrode contact 123 and the negative electrode contact 124 can be connected to the vital sign detection module 30 in the host, and the temperature-sensing electrode 125 can be connected to the temperature-sensing module 40 in the host. When the front side of the cover plate body 11 is in contact with the skin, the vital sign module can detect physiological information such as heart rate, respiratory rate, and blood oxygenation. At the same time, the skin temperature is transmitted to the temperature-sensing electrode 125, and the temperature-sensing module 40 detects the skin surface temperature. The temperature-sensing electrode 125 and the positive and negative electrodes are all integrated into the cover plate structure 10, which can reduce space occupation.

[0064] Please refer to some embodiments of this utility model. Figure 4 The housing structure 20 contains a light emitter 31 and a light receiver 32, with an annular light-blocking structure 50 between them. The light emitter 31 emits light, and the light receiver 32 receives light. The light-blocking structure 50, located between the light receiver 32 and the light emitter 31, isolates the space between them, reducing the mutual interference of light between the two areas.

[0065] In some embodiments, the light-blocking structure 50, the light emitter 31, and the light receiver 32 are all orthogonally projected along the thickness direction of the cover plate structure 10. The light-blocking structure 50 is annular, and the light emitter 31 is disposed in the circular area inside the light-blocking structure 50 and in the annular area outside the light-blocking structure 50.

[0066] In some embodiments, when the cover structure 10 is installed on the host, the first light-shielding area 142 can be configured in conjunction with the light-blocking structure 50 to further enhance the isolation of light in the areas where the light receiver 32 and the light emitter 31 are located.

[0067] In some embodiments, the light-blocking structure 50 is made of black silicone, black foam, etc.

[0068] In some embodiments, a plurality of light emitters 31 are arranged in a ring around each other, and a plurality of light receivers 32 are arranged in a ring around each other.

[0069] In some embodiments, the light emitter 31 is an LED and the light receiver 32 is a PD diode.

[0070] In some embodiments of this utility model, the electronic device further includes a temperature sensing module 40 and a vital signs detection module 30, the vital signs detection module 30 including a light emitter 31 and a light receiver 32.

[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
