It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

Furthermore, in this context, it also needs to be understood that when it is mentioned that an element is connected "on" or "under" another element, it can not only be directly connected "on" or "under" another element, but can also To be indirectly connected "on" or "under" another element through an intervening element.

An embodiment of the present application provides an electronic device, specifically, a watch, a wristband, or a finger ring, which can be worn by a user and has a human body feature detection function or device function. In this application, the electronic device is preferably a watch. As shown in Fig. 1, the electronic equipment includes an electronic equipment housing 1, and the electronic equipment housing 1 includes a body 11, on which a photoplethysmogram light-shielding structure 42, a photoplethysmogram filter structure, an electrocardiogram electrode structure 41, and an electrocardiogram electrode structure 41 are formed. One or a combination of two or more of conductive column structures, thermal conductive sheets, thermal conductive columns, and radio frequency antennas.

In this embodiment, the housing 1 of the electronic device can detect human body characteristics by contacting with human skin, and the detection of each human body characteristic requires a special structure on the housing 1 of the electronic device as the basis for realization. For example, the electronic device may have the function of detecting the heart rate of the human body. The heart rate refers to the number of heartbeats per minute of a normal person in a quiet state. The heart rate is generally measured by photoplethysmography (photo plethysmo graphic, PPG). The principle of PPG is: when light of a specific wavelength hits the skin, the absorption of light by muscles, bones, etc. is basically unchanged under the premise that the measurement site does not move significantly. The absorption of light varies with the flow of blood. Therefore, the reflected light can reflect the characteristics of blood flow after being received and processed, so as to obtain the heart rate. Therefore, the electronic device measures the heart rate through PPG and requires the housing 1 of the electronic device to have an emission window 13 and a reception window 14 to realize the emission and reception of the measurement light, and the emission window 13 and the reception window 14 are optically isolated from each other, that is, the emission The measurement light emitted by the window 13 will not be directly received by the receiving window 14 , and the specific structure capable of realizing light isolation may be a photoplethysmogram light-isolation structure 42 and a photoplethysmogram light-filtering structure. Wherein, the photoplethysmogram light-blocking structure 42 not only prevents the measurement light from being directly received by the receiving window 14 , but also blocks the measurement light from being reflected by the glass surface when passing through the window glass and entering the receiving window 14 . And the photoplethysmogram filter structure can make a part of light pass through. It should be noted that the light-shielding structure and the light-filtering structure are not limited to the above-mentioned photoplethysmogram light-shielding structure 42 and the photoplethysmogram light-shielding structure, and can also be applied to other scenarios that require light-shielding or light-filtering functions.

Exemplarily, as shown in FIG. 1 , the structure capable of realizing optical isolation may specifically be a photoplethysmographic light-isolation structure 42, which includes an inner ring 421 and an outer ring 422, and the emission window 13 corresponds to a PPG light source It is set so that the measuring light is sent to the human skin through the emission window 13, and the receiving window 14 is arranged between the inner ring 421 and the outer ring 422 for the light reflected back after the human skin receives the measuring light to pass through, so that This reflected light is received by an optical sensor such as a photodiode. The inner ring 421 as a light-isolation structure can block the measurement light from being directly received by the receiving window 14, and can also block the measurement light from being reflected by the glass surface when passing through the window glass to enter the receiving window 14; the outer ring 422 as a light-isolation structure can block the Light in the surrounding environment passes through the window glass and is reflected by the glass surface to enter the receiving window 14 . In addition, as shown in Figure 1, an electrocardiogram electrode structure 41 is arranged on the periphery of the outer ring 422. The electrocardiogram electrode structure 41 is semi-circular, and there are two symmetrically arranged on the periphery of the outer ring 422. The structure 21 and the two electrocardiogram electrode structures 41 are respectively arranged on both sides of the support structure 21 , and the support structure 21 can separate the two electrocardiogram electrode structures 41 .

For another example, the electronic device may have the function of detecting and obtaining an electrocardiogram (ECG), which requires the housing of the electronic device to have an electrocardiogram electrode structure 41 and an electrocardiogram conductive column structure.

For another example, for the body 11 including the heat conduction sheet and the heat conduction column, the function of the electronic device to measure the temperature of the human body can be realized.

Different electronic devices have different functions, and the structure of the housing 1 of the electronic device is also different. Therefore, the body 11 of the electronic device housing 1 is formed with a photoplethysmographic light isolation structure 42 and a photoplethysmographic light filtering structure according to the functions to be realized. , one or more of an electrocardiogram electrode structure 41 , an electrocardiogram conductive post structure, a heat conduction sheet, a heat conduction post, and a radio frequency antenna.

Fig. 24 is another schematic diagram of the structure of the body in Fig. 1. As shown in Fig. 24, the first circle H is located at the center of the body 11, and the second circle I, the third circle J and the fourth circle K are placed sequentially from inside to outside Set on the periphery of the first circle H. The first circle H is a solid cylindrical structure, and the second circle I, the third circle J and the fourth circle K are all hollow tubular structures. Wherein, the first circle H, the second circle I, the third circle J and the fourth circle K may be made of different materials, or part of the materials may be the same. Exemplarily, the second circle I can be a light-shielding structure, or both the second circle I and the fourth circle K can be a light-shielding structure, and the refractive index of the second circle I and the fourth circle K is required to be smaller than that of the first circle H and The refractive index of the third ring J. Exemplarily, the refractive index of the first circle H and the third circle J shown in FIG. 24 are the same, the refractive index of the second circle I and the fourth circle K are the same, and the refractive index of the second circle I is smaller than that of the first circle H the refractive index. Of course, the refractive index of the first circle H and the third circle J can be different, and the refractive index of the second circle I and the fourth circle K can also be different, only need to ensure that the refractive index of the second circle I is smaller than the first circle H, The refractive index of the second circle I is also smaller than that of the third circle J, and it is only necessary to realize the light-shielding function of the second circle I and the fourth circle K.

Exemplarily, the second circle I and the fourth circle K can also be conductive materials, so that the second circle I and the fourth circle K can form the conductive electrodes of the ECG; or the first circle H and the third circle J can also be conductive materials. material such that the first ring H and the third ring J can also constitute the conductive electrodes of the ECG.

In addition, any one of the first circle H, the second circle I, the third circle J, and the fourth circle K can be used as a heat conduction sheet to provide a low thermal resistance heat conduction path from the skin to the internal sensor of the watch. The heat conduction sheet and the ECG electrode can be used simultaneously. On any one of the first circle H, the second circle I, the third circle J and the fourth circle K. If it is necessary to realize the PPG light-shielding structure, for example, the second circle I and the fourth circle K can form the conductive electrodes of the ECG, and the first circle H and the third circle J can be used as the PPG emission and reception windows. At this time, the second circle I and the fourth circle K can also be used as a light-shielding structure; the first circle H and the third circle J form the conductive electrodes of the ECG, which is also similarly realized. The first circle H and the third circle J are used as PPG transmitting and receiving windows, and can also be used as ECG electrodes at the same time. At this time, the second circle I and the fourth circle K are only used as light-isolation structures; The circle K is used as the PPG emission and reception window, and can also be used as the ECG electrode at the same time. The first circle H and the third circle J are only used as light-shielding structures.

In addition, the thickness of the main body 11 can be 100 μm to 200 μm, and the main body 11 can be attached to the inner surface of the bottom case of the watch as a whole to form a light-shielding structure, which replaces the use of the Fresnel film, and can avoid observing the bottom case of the watch through the main body 11 The internal structure can enhance the appearance of the watch.

The existing method for preparing the housing 1 of an electronic device performs separate processes for different human body feature detection structures. Therefore, when the electronic device has multiple human body feature detection functions, the manufacturing process of the electronic device housing 1 is long and complicated, and the cost is high. higher.

To this end, the embodiment of the present application provides a method for preparing an electronic device housing 1, as shown in Figures 2-4, including the following steps:

Step S1: Prefabricate the first liquid glass substrate.

The glass substrate is the main material of the housing 1 of the electronic device, and the glass substrate can be formed into a variety of material forms, such as liquid, solid, molten, etc. In this embodiment, the glass substrate can be manufactured into a liquid state in advance, so that the subsequent processing.

Step S2: adding materials for realizing human body feature detection function or equipment function to the set area of the first liquid glass substrate to form a composite material.

The electronic device can have the function of detecting human heart rate, electrocardiogram, body temperature, etc. These functions need to be realized with corresponding materials on the electronic device casing 1. Therefore, the first liquid glass substrate is added in the set area to realize human body feature detection. Functional or device functional materials to form composite materials to achieve the above functions. Wherein, the set area can be the area on the first liquid glass substrate used to process the human body feature detection function or equipment function. This area can be one or multiple, and the shape of this area can also be It can have various shapes, such as rectangle, square, circle, ring, semi-ring or irregular shape, so that the material used to realize the function of human body feature detection or equipment function can be formed into the above corresponding shape after molding.

Step S3: integrally processing the composite material into a blank.

The function of the electronic device to measure human heart rate, electrocardiogram, body temperature, etc. also requires the functional material on the electronic device casing 1 to have a special structural assistance. Therefore, after adding materials for realizing the human body feature detection function or device function, the functional material It is integrally formed with the first liquid glass base material to form a blank, and the blank has a special structure required for the electronic device to detect human body features. At the same time, since the functional material and the first liquid glass substrate are integrally formed, there is no need to separately process the functional material after the first liquid glass substrate is formed, which simplifies the production process of the electronic device casing 1, thus reducing the production cycle of the electronic device casing 1 , reducing the production cost of the electronic equipment housing 1 .

Wherein, after the functional material and the first liquid glass substrate are formed into an integral blank, the blank can be cut to form a shell, without post-processing the cut material, such as metal plating to form ECG electrodes, coating light-shielding ink Post-processing such as the formation of PPG light-shielding structures. Therefore, this embodiment can adopt an integral processing and molding method, which simplifies the production process of the electronic equipment housing 1 , thereby reducing the production cycle of the electronic equipment housing 1 and reducing the production cost of the electronic equipment housing 1 .

Step S4: Cutting the blank to form an electronic device housing 1 .

As shown in Figure 3 and Figure 4, the molding blank can include at least one or several areas with special structures formed by special materials, and the housings of multiple electronic devices can be cut out on the molding blank, so the process efficiency is high, and a single electronic device The average production cycle of the casing 1 is short. Wherein, as shown in FIG. 3 , after the molten glass is formed in the mold, the shape of the glass substrate 2 may be the same as that of the mold. The glass substrate 2 in this embodiment can be shaped as a rectangle, of course, it can also be shaped as a square, a circle or other shapes.

In a glass substrate 2, there may be multiple regions with special structures formed by special materials. For example, as shown in FIG. Distribution, each special area can include one or more different special materials, for example, each special area can only include materials used to detect PPG function, or only include materials used to detect ECG function, and can also be used at the same time Including materials used to detect PPG and ECG functions, or materials used to detect other human body characteristics, such as thermally conductive materials, etc. The above nine areas can be cut separately to form the outer shell of the watch, thus, in one glass substrate 2 molding process, multiple areas with multiple special structures formed by special materials can be realized at the same time, which simplifies the process and improves production efficiency.

Therefore, by adopting the preparation method of the electronic device casing 1 provided by the present application, the blank can have various functional structures 4 for human body feature detection during the one-time molding process of the first liquid glass substrate, solving the problem of current electronic device casings. 1, the production process of the electronic equipment casing 1 is reduced, and the production cycle of the electronic equipment casing 1 is shortened. Wherein, the functional structure is a part of the structure manufactured with a certain shape and volume and needs to be embedded in the first liquid glass substrate.

In addition, in the process of forming the first liquid glass base material, a support structure 21 can also be added to the first liquid glass base material. The support structure 21 can realize the series connection of each of the above-mentioned special structures in the blank, and improve the strength of the blank. Provide support for the blank, prevent the blank from breaking during the cutting process, and at the same time improve the strength of the electronic device casing 1 cut out of the blank, so that it is not easy to be damaged.

In a specific implementation, as shown in Figure 5, for step S2: adding materials for realizing the human body feature detection function or device function in the area set by the first liquid glass substrate to form a composite material, specifically include:

Step A1: Prefabricate the functional structure 4 from the materials used to realize the human body feature detection function or device function.

The functional structure 4 is prefabricated, so that the functional structure 4 has the function or equipment function of assisting the electronic equipment to realize human body feature detection. The functional structure 4 may be a structure with a solid shape, that is, a part of the structure manufactured with a certain shape and volume that needs to be embedded in the first liquid glass substrate.

Step A2: Embedding the functional structure 4 into a predetermined area of the first glass substrate.

In the process of forming glass from liquid to solid, the functional structure 4 is embedded and formed into a glass composite structure together with the glass liquid. For example, in the production process of float glass, the functional structure 4 is put into the glass forming equipment, for example, the functional structure 4 is put into the set area in the tin bath. As another example, in the glass drawing process, the functional structure 4 is embedded. For another example, the functional structure 4 is placed in the mold in advance, glass liquid is poured, and the glass composite material embedded with the functional structure 4 is formed by rolling. For another example, the functional structure 4 and the molten glass are continuously rolled into a composite glass ribbon by a calender. Thus, through the preparation process of the electronic equipment casing 1, the blank of the electronic equipment casing 1 can have various human body feature detection functions or functional structures 4 required by the device function through a single processing process, and multiple electronic equipment can be obtained after cutting the blank. The shell 1 of the device has a simple process, so that the production cost of the shell 1 of the electronic device is low and the production cycle is short. In addition, the casing 1 of the electronic device obtained after cutting can be further polished and followed by secondary processing to obtain the final finished casing 1 .

In a specific implementation, as shown in Fig. 3, Fig. 4 and Fig. 6, for step A1: prefabricating the material used to realize the human body feature detection function or equipment function into a functional structure 4, specifically including:

Step B1: Prefabricate the second liquid glass substrate.

Step B2: Incorporating microcrystalline seeds for realizing human body feature detection function or device function into the second liquid glass substrate.

Step B3: Processing the second liquid glass substrate doped with microcrystalline seeds to form a glass matrix.

Step B4: reprocessing the glass substrate so that the microcrystalline seeds grow crystals to form a functional structure 4 for realizing the human body feature detection function or device function.

Wherein, the second liquid glass substrate can be a part of the first liquid glass substrate, that is, after the first liquid glass substrate is prefabricated, a part is extracted from the first liquid glass substrate as the second liquid glass substrate. Certainly, the second liquid glass substrate can also be a glass substrate prepared separately, and it can be prepared twice separately from the first liquid glass substrate. Add microcrystalline seeds that can realize human body feature detection function or equipment function to the second liquid glass base material to make a glass matrix, and reprocess the glass matrix to make the microcrystalline seeds that can realize human body feature detection function or equipment function press The set structure was grown to form the functional structure 4 . Among them, reprocessing the glass matrix can promote the crystallization and growth of microcrystalline seeds, and reduce the time required to form the functional structure 4 . For example, as shown in Figure 4, the microcrystalline seed crystallization can be made to form a photoplethysmogram light-shielding structure 42, or an electrocardiogram electrode structure 41, and the photoplethysmogram light-shielding structure 42 and the electrocardiogram electrode structure 41 can also be embedded in the set area respectively. .

In a specific implementation, as shown in Figure 3 and Figure 7, for step S2: add materials for realizing the function of human body feature detection or device function in the area set by the first liquid glass substrate to form a composite materials, including:

Step C1: Adding microcrystalline seeds for realizing human body feature detection function or device function to the set area of the first liquid glass substrate.

Step C2: Process the first liquid glass substrate doped with microcrystalline seeds to form a glass substrate 2 .

Step C3: reprocessing the glass substrate 2 to grow the microcrystalline seeds to form a functional structure 4 for realizing the function of detecting human body features or equipment.

The glass substrate is prefabricated into a liquid state by heating, and the obtained molten glass is contained in a specific mold. The mold can define the shape of the molten glass, and adding it to the set area of the molten glass in the mold can realize the human body feature detection function or equipment. Functional microcrystalline seeds are made into glass substrate 2, and the glass substrate 2 is subjected to controllable treatment, so that the added microcrystalline seeds that can realize the function of human body feature detection or equipment function grow crystals, so that the area set by glass substrate 2 Form the functional structure 4. Wherein, the set area may be an area expected to be cut into the housing 1 of the electronic device. For example, the realization of ECG function requires an electrode structure, so microcrystalline seeds with high conductivity and low half-cell potential formed with skin tissue, such as AgCl, Ni, etc. The controlled treatment causes ions with high conductivity to crystallize on the microcrystalline seeds to form an electrode structure that runs through the glass substrate 2 . For another example, the realization of the ECG function requires conductive pillars, so high-conductivity microcrystalline seeds, such as one or a combination of Au, Cu, and AgCl, are doped in the thickness of the set area in the glass liquid. For another example, in terms of measuring the temperature of the human body, microcrystalline seeds with high conductivity, such as Cu, can be doped on the surface in a set area in the glass liquid.

Therefore, through this process method, the process is simple, so that the production cost of the electronic equipment casing 1 is low and the production cycle is short.

Wherein, the above-mentioned set area may include the first area, and the first area may be used for doping microcrystalline seeds to realize the function of ECG detection. The first region may have a set position and shape, and the microcrystalline seeds used to realize the ECG detection function are only doped to the first region, while the regions other than the first region are not doped with the microcrystalline seeds used to realize the ECG detection function. crystal seeds, so that the microcrystal seeds can only be grown in the first region to form a functional structure for detecting the user's ECG function.

In a specific operation, only one of the processes can be used for treatment, or two or three of them can be combined for treatment. For example, heat treatment and laser treatment can be applied to the glass substrate 2 at the same time, laser treatment and ion beam treatment can also be used at the same time, and heat treatment, laser treatment and ion beam treatment can also be used at the same time, which is conducive to deeper ion implantation and faster response time ,Improve efficiency.

In addition, the incorporation of a variety of microcrystalline seeds with different functions can be achieved through multiple mask operations. For example, for the preparation of the electronic device housing 1 with ECG and PPG functions, a masking operation may be performed first to incorporate microcrystalline seeds capable of realizing either ECG or PPG. Then, another mask operation can be performed to incorporate the microcrystal seeds capable of realizing the other of ECG or PPG, so that the precision of doping the microcrystal seeds capable of realizing ECG or PPG can be ensured respectively.
