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

[0002] With technological advancements, the development of wearable smart devices such as smartwatches and smart bracelets is accelerating. For example, these devices typically incorporate a light source and a light detector. The light source emits light, and the light detector receives the parameters of light reflected from the skin of a living person to measure health data such as pulse and blood oxygen concentration.

[0013] In one embodiment, the light blocking layer is configured as an ink layer, a metal layer or a light-shielding tape; and / or the cover body is made of sapphire or glass; and / or the texture of the light-focusing layer includes a Fresnel texture.

[0016] A plurality of second conductive layers are provided on the second surface side of the cover body and are spaced apart from each other;

[0020] According to another aspect of the present application, an embodiment of the present application provides a wearable device, including:

[0021] A housing assembly, comprising a housing body and a cover according to any one of the above embodiments, wherein the housing body and the cover are connected to each other and define an accommodating cavity; and

[0022] At least one light source and at least one light detection element are both disposed in the accommodating cavity; the light sources and light exit holes are disposed in a one-to-one correspondence, the light exit holes being located on the light exit path of the corresponding light source; the light detection elements and light entrance holes are disposed in a one-to-one correspondence, the light entrance holes being located on the light receiving path of the corresponding light detection elements;

[0024] In the above-mentioned cover and wearable device, the cover includes at least a cover body, a light-blocking layer, and a light-collecting layer. By configuring the cover body as a light-transmitting member and providing a light-blocking layer with a light-exit hole and a light-entry hole on the first surface of the cover body, the light emitted by the light source can be emitted to the outside of the wearable device through the light-exit hole, and the emitted light can enter the wearable device through the light-entry hole after reflection, so that the corresponding parameters can be detected by means of the emitted light and the reflected light. In this process, by providing the light-collecting layer at a position corresponding to the light-exit hole, the emitted light can be collected by means of the light-collecting layer, thereby improving the sensitivity and accuracy of the detection process. Since at least a portion of the light-collecting layer contacts the first surface via the corresponding light-exit hole, the light only needs to pass through the cover body and the light-collecting layer when it is emitted, minimizing the number of interfaces that the light needs to pass through when it is emitted. At the same time, since the reflected light only needs to pass through the cover body when it enters through the light-entry hole, the number of interfaces that the light needs to pass through when it enters is also minimized. In this way, the transmittance of the light is further improved, thereby further improving the sensitivity and accuracy of the detection process. Therefore, in the embodiments of the present application, by configuring the cover body as a light-transmitting member, forming light exit holes and light entrance holes with the aid of a light-blocking layer, and then providing a light-collecting layer at the corresponding light exit holes, detection accuracy and test performance can be improved. Furthermore, since the light-collecting layer is provided at the corresponding light exit holes, it can shield the relevant light-emitting components within the wearable device, thereby improving the overall appearance and performance.

[0059] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0065] To facilitate the introduction of the cover provided by the embodiment of the present application, the wearable device involved in the embodiment of the present application is first exemplarily described.

[0066] In the embodiments of the present application, the wearable device may be a smart bracelet, a smart watch, or the like. For example, a smart watch, in addition to indicating the time, may also have functions such as making calls, sending and receiving messages, and recording exercise steps. It may also have functions for monitoring human physiological conditions such as heart rate, blood oxygen, electrocardiogram, and sleep quality. Of course, wearable devices may also utilize sensors such as temperature, air pressure, altitude, and gyroscopes to achieve the desired functions, which are not specifically limited here.

[0067] Please refer to Figure 1 and Figure 2 , Figure 1 FIG2 shows a front view of a wearable device 10 provided in an embodiment of the present application. Figure 2 A rear structural diagram of a wearable device 10 provided in an embodiment of the present application is shown. The wearable device 10 may include a watch head 100 and a watch strap 200 connected to the watch head 100.

[0068] The required functional modules can be set up in the watch head 100 to achieve the required functions. The watch head 100 includes a housing assembly 110 and the functional modules accommodated in the housing assembly 110. The housing assembly 110 includes a shell body 111 and a cover body 112. The shell body 111 and the cover body 112 are the outer shell structure of the wearable device 10. The two shell bodies 111 and the cover body 112 are connected to define a receiving cavity Q for accommodating the functional modules. Figure 1 The dotted line in the figure shows that the accommodating cavity Q is located inside the wearable device 10, and only the approximate position of the accommodating cavity Q is shown. The housing assembly 110 can protect the corresponding functional modules. Figures 11 to 13, the functional module may include a light source 120, a light detection element 130 and a display module 140. The light source 120 and the light detection element 130 are located in the accommodating cavity Q. The light source 120 and the light detection element 130 can be used in conjunction with the cover body 112 to realize the corresponding monitoring function, which will be described in detail below. The display module 140 is installed on the side of the shell body 111 that is away from the cover body 112. The display module 140 can be a component that can provide a human-computer interaction interface. The strap 200 can bind the watch head 100 to the user's wrist to realize the wearability of the wearable device 10. At this time, the display module 140 is set away from the user's wrist.

[0069] Furthermore, an input element 150 is provided on the side of the housing. Input element 150 is configured to receive input from the user or the environment. For example, input element 150 may include a push button, a touch-activated button, a capacitive touch button, a dial, etc. As another example, input element 150 may provide dedicated or primary functions, including a power button, volume button, home button, scroll wheel, and camera button, making it easier for the user to perform relevant operations.

[0070] It should be noted that the light source 120 can be a light-emitting diode, and the light detection element 130 can be a photosensor. The detection light emitted by the light source 120 can be transmitted to the outside of the wearable device 10, and after being absorbed by the user's blood and other tissues, part of it is emitted, and the reflected detection light can be transmitted to the accommodating cavity Q and can be received by the light detection element 130. In this process, the light is absorbed and attenuated by the wrist skin muscle tissue and blood, so that the light intensity detected by the light detection element 130 is weakened. For example, the absorption of light by skin, muscle tissue, etc. remains constant throughout the blood circulation, while the blood content in the skin will change regularly under the action of the heart pumping blood, so that the light intensity received by the light detection element 130 will also change in a pulsating manner. In this way, corresponding monitoring can be achieved.

[0071] The display module 140 can be a display screen such as LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), QLED (Quantum Dot Light Emitting Diodes), or a display screen such as Mini-LED (Mini Light Emitting Diode Display) or Micro-LED (Micro Light Emitting Diode Display) to display the corresponding image.

[0072] In some embodiments, please refer to Figures 3 to 6 , Figure 3 FIG. 1 shows a schematic diagram of the three-dimensional structure of the cover body 112 provided in an embodiment of the present application. Figure 4 1 is a schematic diagram of the exploded structure of the cover 112 provided in one embodiment of the present application. The cover 112 includes a cover body 112a, a light blocking layer 112b and a light focusing layer 112c.

[0073] The cover body 112a is configured as a light-transmitting member. That is, the cover body 112a has a certain light-transmitting ability. The cover body 112a has a first surface m1 and a second surface m2 arranged opposite to each other. The cover body 112a can be arranged in a plate-like shape. The first surface m1 and the second surface m2 of the cover body 112a can be arranged opposite to each other along the thickness direction of the cover body 112a, and the thickness direction of the cover body 112a is the first direction F1 illustrated in the figure. The first surface m1 can be a concave surface, and the second surface m2 can be a convex surface. The first surface m1 of the cover body 112a can be located inside the accommodating cavity Q, and the second surface m2 can be located outside the accommodating cavity Q. That is, the first surface m1 is the inner surface, and the second surface m2 is the outer surface. Alternatively, the second surface m2 of the cover body 112a is located inside the accommodating cavity Q, and the first surface m1 of the cover body 112a is located outside the accommodating cavity Q. That is, the first surface m1 is the outer surface, and the second surface m2 is the inner surface. In the embodiment of the present application, the first surface m1 of the cover body 112 a is an inner surface, and the second surface m2 is an outer surface.

[0074] The light-blocking layer 112b is a layer structure capable of blocking light. The light-blocking layer 112b is provided on the first surface m1 of the cover body 112a. The light-blocking layer 112b is provided with at least one light-emitting hole k1 and at least one light-entering hole k2. That is, the light-blocking layer 112b is provided on the cover body 112a so that light can be emitted from the light-emitting hole k1 on the light-blocking layer 112b and can enter from the light-entering hole k2 on the light-blocking layer 112b. The light-emitting hole k1 and the light-entering hole k2 are independent of each other. Figure 2 、 Figure 3 and Figure 5 , Figure 5 FIG1 shows a front view of the cover 112 provided in an embodiment of the present application, with dotted lines indicating the approximate positions of the light exit hole k1 and the light entrance hole k2. Figure 6 and Figure 7 , Figure 6 FIG. 1 shows a rear structural diagram of a cover body 112 provided in an embodiment of the present application. Figure 7The figure shows a rear view of the cover body 112 provided in one embodiment of the present application, with the light-gathering layer 112c removed. The number and arrangement of the light-emitting holes k1 and the number and arrangement of the light-entering holes k2 can be set according to actual use requirements and are not specifically limited here. In the embodiment of the present application, a situation is shown in which three light-emitting holes k1 are provided and two light-entering holes k2 are provided, wherein one light-emitting hole k1 is located in the middle of the cover body 112, and the remaining light-emitting holes k1 and all the light-entering holes k2 are arranged in sequence around the circumference of the light-emitting hole k1 located in the middle of the cover body 112. Along the circumference of the light-emitting hole k1 located in the middle of the cover body 112, the light-emitting holes k1 and the light-entering holes k2 are arranged alternately.

[0075] The light-gathering layer 112c is a layer structure capable of gathering light. The light-gathering layer 112c is provided on the first surface m1 side of the cover body 112a. Among all the light-emitting holes k1, there is a light-emitting hole k1 provided with the light-gathering layer 112c. That is, when there is only one light-emitting hole k1, the light-gathering layer 112c is provided in the light-emitting hole k1. When there are multiple light-emitting holes k1, the light-gathering layer 112c is provided in at least one light-emitting hole k1. When the light-gathering layer 112c is provided in a one-to-one correspondence in the multiple light-emitting holes k1, there are also multiple light-gathering layers 112c, and the multiple light-gathering layers 112c are independent of each other. The settings can be made according to the specific usage and are not specifically limited here.

[0076] The light exit hole k1 provided with the light collecting layer 112c is defined as a target hole, and at least a portion of the light collecting layer 112c contacts the first surface m1 via the corresponding target hole. It is understood that the portion of the first surface m1 corresponding to the target hole can be exposed through the target hole, thereby allowing at least a portion of the light collecting layer 112c located at the target hole to contact the exposed portion of the first surface m1. Figures 8 to 10 , Figure 8 Shown Figure 6 The cross-sectional structure diagram with the cross-sectional direction in the AA direction is shown in the figure. Figure 9 Shown Figure 6 The cross-sectional structure diagram with the cross-sectional direction in the BB direction is shown in the figure. Figure 10 Shown Figure 6 In the cross-sectional structural diagram with the cross-sectional direction CC, it can be seen that the corresponding light exit hole k1 is provided with a light-collecting layer 112c. The figure schematically illustrates the location of the light exit hole k1. In the embodiment of the present application, each light exit hole k1 is provided with a light-collecting layer 112c, and all light exit holes k1 are target holes.

[0077] The following describes the process of using the cover 112 provided in the embodiment of the present application in conjunction with the light source 120 and the light detection element 130 by way of example, with the first surface m1 of the cover 112 being the inner surface and the second surface m2 being the outer surface, but the present invention is not limited thereto.

[0078] Combined with reference Figures 11 to 13 , Figure 11 Shown in Figure 8 The schematic diagram of the structure of the cover 112 and the light source 120 under the perspective shown, Figure 12 Shown in Figure 9 The schematic diagram of the structure of the cover 112, the light source 120 and the light detection element 130 under the perspective shown, Figure 13 Shown in Figure 10 The schematic diagram of the structure of the cover body 112 and the light source 120 under the perspective shown is shown. In the figure, the approximate location of the accommodating cavity Q is indicated by a dotted line. The light emitted by the light source 120 is the outgoing light w1, and the light received by the light detection element 130 is the incident light w2. The second surface m2 can be used to contact the human skin. The outgoing light w1 is focused by the focusing layer 112c at the corresponding light output hole k1 and then emitted from the second surface m2 of the cover body 112a. The emitted outgoing light w1 can be reflected by the human skin to form the incident light w2. The incident light w2 is emitted into the accommodating cavity Q through the cover body 112a and the light input hole k2, and is received by the light detection element 130, thereby realizing the corresponding monitoring function.

[0079] The following is further illustrated with reference to the relevant comparative examples of the present application, but is not limited thereto.

[0080] Combined with reference Figure 14 and Figure 15 , Figure 14 It shows a schematic cross-sectional structure diagram of the first comparative example of the present application at one viewing angle, Figure 15 A schematic diagram of the cross-sectional structure of the first comparative example of the present application at another viewing angle is shown. In the first comparative cover body 1 provided in the first comparative example of the present application, a first comparative light-blocking layer 1b is provided on one side surface of the first comparative cover body 1a, and a first comparative light-emitting hole 1e and a first comparative light-entering hole 1f are provided on the first comparative light-blocking layer 1b. A first comparative light-focusing layer 1c is provided on the side surface of the first comparative light-blocking layer 1b facing away from the first comparative cover body 1a with the aid of a first comparative glue 1d, and a focusing structure 1g is provided on the first comparative light-focusing layer 1c at a position corresponding to the first comparative light-emitting hole 1e.

[0081] Combined with reference Figure 16 and Figure 17 , Figure 16 It shows a schematic cross-sectional structure diagram of the second comparative example of the present application at a viewing angle, Figure 17A schematic diagram of the cross-sectional structure of the second comparative example of the present application at another viewing angle is shown. In the second comparative cover body 2 provided in the second comparative example of the present application, a second comparative light-blocking layer 2b is provided on one side surface of the second comparative cover body 2a, a second comparative light-blocking layer 2b is provided on the second comparative light-emitting hole 2e and a second comparative light-entering hole 2f, and a second comparative light-focusing layer 2c is provided at the second comparative light-emitting hole 2e with the aid of a second comparative glue 2d.

[0082] It can be seen that in the first comparative example of the present application, light is emitted through the first comparative light-emitting hole 1e and needs to pass through the "first comparative light-gathering layer 1c", "air", and "first comparative cover body 1a". In the second comparative example of the present application, light is emitted through the second comparative light-emitting hole 2e and needs to pass through the "second comparative light-gathering layer 2c", "second comparative glue 2d", and "second comparative cover body 2a". That is, in both the first comparative example of the present application and the second comparative example of the present application, since the light needs to be emitted through three material interfaces, the light will be refracted and reflected twice, thereby reducing the transmittance of the light and reducing the detection sensitivity. At the same time, the existence of the three material interfaces also makes the cover body thicker as a whole, occupying the internal space or external space of the wearable device. In addition, in the first comparative example of the present application, the first comparative light-gathering layer 1c also exists on the light-entering path of the first comparative light-entering hole 1f, which will also affect the transmittance of the light. In the second comparative example of the present application, multiple second comparative light-gathering layers 2c need to be pasted, which will also reduce the production efficiency.

[0083] In the cover body 112 provided in the embodiment of the present application, since at least a portion of the light-collecting layer 112c is in contact with the first surface m1 by means of the corresponding light-emitting hole k1, the light only needs to pass through the cover body 112a and the light-collecting layer 112c when emitting, which minimizes the interfaces that the light needs to pass through when emitting. At the same time, since the reflected light only needs to pass through the cover body 112a when entering through the light-input hole k2, the interfaces that the light needs to pass through when entering are also minimized. In this way, not only the transmittance of the light is further improved, and the sensitivity and accuracy of the detection process are further improved, but also the overall thickness of the cover body 112 is reduced, and the manufacturing efficiency can be improved.

[0084] Therefore, by configuring the cover body 112a as a light-transmitting member and disposing a light-blocking layer 112b with a light-emitting hole k1 and a light-entering hole k2 on the first surface m1 of the cover body 112a, light emitted by the light source 120 can be emitted from the wearable device 10 through the light-emitting hole k1, and the emitted light can be reflected and enter the wearable device 10 through the light-entering hole k2. The corresponding parameters can be detected using the emitted and reflected light. In this process, by directly disposing a light-collecting layer 112c in contact with the first surface m1 at a position corresponding to the light-exiting hole k1, the emitted light can be concentrated by the light-collecting layer 112c, thereby improving the sensitivity and accuracy of the detection process.

[0085] Therefore, in the embodiment of the present application, by configuring the cover body 112a as a light-transmitting member, and using the light-blocking layer 112b to form the light-emitting hole k1 and the light-entering hole k2, and then providing the light-collecting layer 112c at the corresponding light-emitting hole k1, not only can the detection accuracy and test performance be improved, but the overall thickness of the cover body 112 can also be reduced, thereby improving manufacturing efficiency. In addition, because the light-collecting layer 112c is provided corresponding to the corresponding light-emitting hole k1, it can block the relevant light-emitting components inside the wearable device 10 (such as the light source 120 mentioned above), thereby improving the overall appearance performance.

[0086] In some embodiments, please refer to Figures 8 to 10 The light-collecting layer 112c includes a first portion p1 in contact with the first surface m1 and a second portion p2 in contact with a surface of the light-blocking layer 112b that is away from the first surface m1. The first portion p1 and the second portion p2 are connected to each other.

[0087] In this way, it is not only convenient to manufacture the light-collecting layer 112c, but also convenient to fill the corresponding light-emitting hole k1 with at least a portion of the light-collecting layer 112c, thereby facilitating improvement of light transmittance.

[0088] Of course, in some other embodiments, the light-collecting layer 112c may also include only the first portion p1 in contact with the first surface m1. This may be configured according to specific usage and is not specifically limited here.

[0089] In some embodiments, please refer to Figures 6 to 10 , and combined with reference Figure 18 , Figure 18 A schematic diagram of the projection relationship among the light-collecting layer 112c, the light-emitting hole k1 and the first surface m1 in one embodiment of the present application is shown. The orthographic projection of the target hole on the first surface m1 is within the orthographic projection range of the corresponding light-collecting layer 112c on the first surface m1.

[0090] Specifically, the orthographic projection of the corresponding light exit hole k1 on the first surface m1 is the first projection y1, and the orthographic projection of the corresponding light-collecting layer 112c on the first surface m1 is the second projection y2. The first projection y1 is within the orthographic projection range of the second projection y2. In other words, the first projection y1 is completely covered by the second projection y2. The outer contour of the first projection y1 and the outer contour of the second projection y2 can be as follows: Figure 18 As shown, there is a gap, thereby forming Figures 6 to 10 The light-emitting hole k1 and the corresponding light-collecting layer 112c are matched. In this case, the light-collecting layer 112c includes a first portion p1 and a second portion p2. Of course, the outer contours of the first projection y1 and the second projection y2 can also overlap, thereby forming a structure in which the light-collecting layer 112c includes only the first portion p1 as described above in other embodiments. This configuration can be tailored to specific usage and is not specifically limited here.

[0091] In this way, by making the orthographic projection of the target hole on the first surface m1 located within the orthographic projection range of the corresponding light-collecting layer 112c on the first surface m1, the corresponding light-exit hole k1 can be filled with the light-collecting layer 112c, thereby facilitating the improvement of light transmittance.

[0092] In some embodiments, please refer to Figures 6 to 10 , the light-gathering layer 112c is configured as a light-curing adhesive, and the texture of the light-gathering layer 112c is formed by an embossing process; or, the light-gathering layer 112c is configured as a heat-curing adhesive, and the texture of the light-gathering layer 112c is formed by an embossing process.

[0093] For example, when the light-curing layer 112c is configured as a light-curing adhesive, the light-curing adhesive may be an ultraviolet light-curing adhesive (UV adhesive), specifically, an acrylic resin. When the light-curing layer 112c is configured as a heat-curing adhesive, the heat-curing adhesive may be made of epoxy resin, phenolic resin, or the like.

[0094] Thus, by configuring the light-focusing layer 112c as a light-curing adhesive or a heat-curing adhesive and forming the texture through an embossing process, the manufacturing process is more convenient and the reliability is higher than that illustrated in the aforementioned comparative example.

[0095] In some embodiments, please refer to Figures 6 to 10 , the dyne value of the light blocking layer 112b is greater than or equal to 34N / mm.

[0096] For example, the dyne value of the light blocking layer 112b can be 34N / mm, 36N / mm, 39N / mm, 40N / mm, 41N / mm, 45N / mm or 50N / mm. The upper limit of the dyne value of the light blocking layer 112b is not specifically limited and can be set according to specific usage.

[0097] The dyne value is a measure of surface tension, equivalent to the surface tension coefficient. The dyne value is defined as the force exerted per unit length between two adjacent surfaces. Surface tension can be measured in millinewtons per meter. The dyne value of a surface can be used to evaluate the activation energy of the surface. A higher dyne value of the light-blocking layer 112b indicates a higher surface activation energy, and the light-focusing layer 112c exhibits greater adhesion to the surface of the light-blocking layer 112b and the inner wall of the corresponding light-emitting aperture k1.

[0098] Therefore, when the dyne value of the light blocking layer 112 b is greater than or equal to 34 N / mm, the reliability of the light focusing layer 112 c can be further improved.

[0099] In some embodiments, please refer to Figures 6 to 10 , the reflectivity of the light blocking layer 112b is less than or equal to 5%.

[0100] For example, the reflectivity of the light blocking layer 112b can be 5%, 4%, 3%, 2%, or 1%, which can be set according to specific usage and is not specifically limited here.

[0101] In this way, by controlling the reflectivity of the light blocking layer 112 b , the transmittance of light passing through the light blocking layer 112 b can be further improved.

[0102] In some embodiments, please refer to Figures 6 to 10 The light blocking layer 112b is configured as an ink layer, a metal layer or a light shielding tape.

[0103] Exemplarily, the light-blocking layer 112b can be an ink layer formed on the first surface m1 of the cover body 112a by a spraying process, a silk-screen process, or a pad printing process, and the color of the ink layer can be configured to be black. The light-blocking layer 112b can also be a light-shielding tape bonded to the first surface m1 of the cover body 112a. The light-blocking layer 112b can also be a metal-plated layer formed on the first surface m1 of the cover body 112a by an electroplating process, and the metal can be silver, gold, copper, aluminum, etc., or an alloy thereof. Taking the light-blocking layer 112b as an ink layer as an example, in order to form the light exit hole k1 and the light entrance hole k2, ink is not sprayed, silk-screened, or pad-printed on some areas of the first surface m1 of the cover body 112a. In the embodiment of the present application, the light-blocking layer 112b can be an ink layer, and the material of the ink layer can use matte ink, which is conducive to improving the dyne value of the light-blocking layer 112b.

[0104] In this way, the material of the light blocking layer 112 b can be controlled so that the light blocking layer 112 b can meet the performance requirements.

[0105] In some embodiments, please refer to Figures 8 to 10The material of the cover body 112a includes sapphire or glass. In the embodiment of the present application, the material of the cover body 112a can be glass.

[0106] In this way, by controlling the material of the cover body 112 a , the cover body 112 a can have a certain structural strength and a certain light transmittance.

[0107] In some embodiments, please refer to Figures 6 to 10 , the texture of the light-collecting layer 112 c includes a Fresnel texture.

[0108] This not only facilitates light collection and diffusion, but also reduces the thickness of the light-collecting layer 112c, thereby reducing the overall thickness of the cover body 112a. Furthermore, by using a Fresnel texture, the light-collecting layer 112c can also have a certain covering effect, thereby improving the appearance of the wearable device 10.

[0109] In some embodiments, the cover 112 further includes a plurality of first conductive layers 112d and a plurality of second conductive layers 112e. The plurality of first conductive layers 112d are disposed on the first surface m1 side of the cover body 112a and are spaced apart from each other. The plurality of second conductive layers 112e are disposed on the second surface m2 side of the cover body 112a and are spaced apart from each other. All first conductive layers 112d and all second conductive layers 112e are connected in a one-to-one correspondence.

[0110] Taking the first surface m1 of the cover body 112a as the inner surface as an example, when the aforementioned functional module includes an ECG (electrocardiogram) monitoring module, the second conductive layer 112e can be in contact with the user's skin when the wearable device 10 is in a worn state. At this time, the second conductive layer 112e can be used as a detection electrode of the ECG monitoring module. The second conductive layer 112e can be formed on the second surface m2 by an electroplating process or a magnetron sputtering process, and further connected one-to-one with the first wire layer located on the first surface m1 via the side of the cover body 112a. The first conductive layer 112d can be electrically connected to the relevant components (such as a flexible circuit board) in the aforementioned accommodating cavity Q. The first conductive layer 112d can also be formed on the first surface m1 by an electroplating process or a magnetron sputtering process. Of course, in some other embodiments, when it is necessary to connect to the corresponding functional module to realize the transmission of electrical signals, it can be understood by referring to the aforementioned ECG monitoring module, which will not be repeated here.

[0111] In the embodiment of the present application, two first conductive layers 112d are provided, and the two first conductive layers 112d are symmetrically arranged at the edge of the first surface m1. Two second conductive layers 112e are provided, and the two second conductive layers 112e are symmetrically arranged at the edge of the second surface m2. The number and arrangement of the first conductive layers 112d and the second conductive layers 112e can be set according to specific usage and are not specifically limited here.

[0112] In this way, by providing the first conductive layer 112d and the second conductive layer 112e, it is beneficial to implement the use of corresponding functional modules and further perform monitoring of related functions.

[0113] In some embodiments, please refer to Figure 4 、 Figure 6 、 Figure 7 、 Figure 10 and Figure 13 The light blocking layer 112b is disposed on the side of all first conductive layers 112d away from the first surface m1. A plurality of openings k3 are defined on the light blocking layer 112b. Each opening k3 corresponds to each first conductive layer 112d. Parts of the first conductive layers 112d are exposed through the corresponding openings k3. Figure 10 and Figure 13 FIG. 3 shows the approximate position of the opening k3.

[0114] In this way, it is easy to arrange each layer and it is also beneficial to realize the electrical connection between the first conductive layer 112d and the corresponding functional module.

[0115] In some embodiments, please refer to Figure 4 、 Figure 6 、 Figure 7 、 Figure 10 and Figure 13 The cover 112 further includes a plurality of third conductive layers 112f. All third conductive layers 112f are disposed on a side of the light-blocking layer 112b facing away from the first surface m1 and are spaced apart from one another. All third conductive layers 112f are disposed in a one-to-one correspondence with all first conductive layers 112d, and each third conductive layer 112f is connected to the corresponding first conductive layer 112d via the corresponding opening k3.

[0116] In this way, by configuring the third conductive layer 112f, the first conductive layer 112d can be electrically connected to the corresponding functional module with the help of the third conductive layer 112f.

[0117] It should be noted that the materials of the first conductive layer 112d, the second conductive layer 112e, and the third conductive layer 112f illustrated above can be the same or different. For example, taking the first surface m1 as the inner surface and the second surface m2 as the outer surface, the first conductive layer 112d and the third conductive layer 112f can be made of Cr, and the second conductive layer 112e can be made of CrSiCN. In this way, the second conductive layer 112e can have certain wear resistance, corrosion resistance, and hardness.

[0118] In combination with the situations illustrated in some of the above embodiments, the manufacturing process of the cover body 112 provided in the embodiment of the present application is exemplarily described below, with the first surface m1 of the cover body 112a being the inner surface and the first surface m1 being the concave surface, and the second surface m2 being the outer surface and the second surface m2 being the convex surface, but the present invention is not limited to this.

[0119] In one embodiment, please refer to Figures 3 to 10 The manufacturing method of the cover 112 provided in the embodiment of the present application includes the following steps:

[0120] Step S1: forming an initial second conductive layer on the second surface m2 of the cover body 112a by a magnetron sputtering process, wherein the material of the initial second conductive layer is CrSiCN;

[0121] Step S2: forming an initial first conductive layer on the first surface m1 of the cover body 112a by a magnetron sputtering process. The material of the initial first conductive layer is Cr, and the initial first conductive layer is connected to the initial second conductive layer.

[0122] Step S3: Using a laser removal process, the initial second conductive layer is formed into two second conductive layers 112e symmetrically disposed at the edge of the second surface m2 and spaced apart from each other, and the initial first conductive layer is formed into two first conductive layers 112d symmetrically disposed at the edge of the first surface m1 and spaced apart from each other; the two first conductive layers 112d are connected to the two second conductive layers 112e in a one-to-one correspondence;

[0123] Step S4: Using a silk screen or pad printing process, a light blocking layer 112b having a light exit hole k1, a light entrance hole k2, and an opening k3 is formed on the first surface m1 of the cover body 112a. Portions of the two first conductive layers 112d are exposed through the corresponding openings k3.

[0124] Step S5: forming a third conductive layer 112f at a position corresponding to the opening k3 by a silk screen printing process or a pad printing process, wherein the third conductive layer 112f is connected to the first conductive layer 112d in a one-to-one correspondence;

[0125] Step S6: drip a preset amount of UV glue into the light exit hole k1, and then press the UV glue with a mold press head with a Fresnel texture so that the UV glue can evenly fill the light exit hole k1. Then, UV light can be used to irradiate the UV glue on the second surface m2 side of the cover body 112a to cure the UV glue. Finally, demolding is performed to obtain the light-focusing layer 112c.

[0126] Based on the same invention concept, please continue to refer to Figures 1 to 4 、 Figures 11 to 13 , the embodiment of the present application also provides a wearable device 10, including a shell assembly 110, at least one light source 120 and at least one light detector 130. The shell assembly 110 includes a shell body 111 and a cover body 112 in any of the above embodiments. The shell body 111 and the cover body 112 are connected to each other and define a receiving cavity Q. All light sources 120 and all light detectors 130 are arranged in the receiving cavity Q. The light sources 120 and the light exit holes k1 are arranged in a one-to-one correspondence, and the light exit holes k1 are located on the light exit path of the corresponding light source 120. The light detectors 130 and the light entrance holes k2 are arranged in a one-to-one correspondence, and the light entrance holes k2 are located on the light receiving path of the corresponding light detector 130. Among them, the first surface m1 of the cover body 112a is located in the receiving cavity Q, and the second surface m2 of the cover body 112a is located outside the receiving cavity Q; or, the second surface m2 of the cover body 112a is located in the receiving cavity Q, and the first surface m1 of the cover body 112a is located outside the receiving cavity Q.

[0127] In the embodiment of the present application, the first surface m1 of the cover body 112 a is located in the accommodating cavity Q, and the second surface m2 of the cover body 112 a is located outside the accommodating cavity Q. This is more conducive to improving the overall appearance and reliability of the cover body 112 .

[0128] The advantages possessed by the cover 112 in any of the above embodiments are also possessed by the wearable device 10 and will not be described in detail here.

[0129] In addition to some of the embodiments of the wearable device 10 illustrated above, the wearable device 10 may further include a communication port configured to transmit and / or receive signals or electrical communications from an external device or a separate device. Of course, the wearable device 10 may also include other related accessories and related modules for use with the user, which are not detailed here and can be configured according to specific usage scenarios.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0131] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
