[0002] Currently, some electronic equipment (for example, watches, bracelets, etc.) has the function of detecting human characteristics by contacting the human body skin, such as detecting heart rate, electrocardiogram and body temperature. Each detection of human characteristics needs special structures (for example, electrocardiogram electrodes, heat-conducting columns connected to temperature sensors, etc.) on the bottom shell of the electronic equipment as the basis for implementation, but the existing manufacturing method of the electronic equipment is relatively complex, so the production cost of the bottom shell of the electronic equipment is high and the production cycle is long.

[0110] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0111] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0112] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0113] This application provides an electronic device, specifically a watch, bracelet, or ring that can be worn by a user and has human feature detection or device functions. In this application, the electronic device is preferably a watch. Figure 1 As shown, the electronic device includes an electronic device housing 1, which in turn includes a body 11. The body 11 has one or more of the following structures: a photoplethysmography light-blocking structure 42, a photoplethysmography light-filtering structure, an electrocardiogram electrode structure 41, an electrocardiogram conductive pillar structure, a heat-conducting sheet, a heat-conducting pillar, and a radio frequency antenna.

[0114] In the embodiment, the shell 1 of the electronic device can detect human characteristics by contacting the human skin, and each detection of the human characteristics needs a special structure on the shell 1 of the electronic device as a basis for implementation. For example, the electronic device can have a function of detecting the heart rate of a human body, and 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 a photo plethysmo graphic (PPG) method. The principle of the PPG is that when light of a specific wavelength is shot to the skin, under the premise that there is no large motion at the measurement site, the absorption of light by the muscles, bones and the like is basically unchanged. Since the blood in the arteries is flowing, the absorption of light is different with the flow of blood. Therefore, the reflected light can reflect the characteristics of the blood flow after being received and processed, so as to obtain the heart rate. Therefore, the electronic device requires that the shell 1 of the electronic device has a transmitting window 13 and a receiving window 14 to realize the transmission and reception of the measurement light, and the transmitting window 13 and the receiving window 14 are optically isolated from each other, that is, the measurement light transmitted by the transmitting window 13 will not be directly received by the receiving window 14. The structure that can realize optical isolation can be a photo plethysmo graphic light isolation structure 42 and a photo plethysmo graphic light filtering structure. The photo plethysmo graphic light isolation structure 42 not only blocks 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. The photo plethysmo graphic light filtering structure can make part of the light to be transmitted. It should be noted that the light isolation structure and the light filtering structure are not limited to the photo plethysmo graphic light isolation structure 42 and the photo plethysmo graphic light filtering structure, and can also be applied to other scenes that have a demand for light isolation or light filtering.

[0115] As shown in FIG. 1, Figure 1 the structure that can realize optical isolation can be a photo plethysmo graphic light isolation structure 42. The photo plethysmo graphic light isolation structure 42 includes an inner ring 421 and an outer ring 422. The transmitting window 13 is provided corresponding to a PPG light source, so that the measurement light can pass through the transmitting window 13 and be transmitted to the human skin. The receiving window 14 is arranged between the inner ring 421 and the outer ring 422, so that the light reflected by the human skin after receiving the measurement light can pass through the receiving window 14 and be received by the optical sensor such as a photo diode. 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 and entering the receiving window 14. The outer ring 422 as a light isolation structure can block the light in the environment outside the outer ring 422 from being reflected by the glass surface when passing through the window glass and entering the receiving window 14. In addition, as shown in FIG. 1, Figure 1As shown, an electrocardiogram (ECG) electrode structure 41 is arranged around the outer ring 422. The ECG electrode structure 41 is semi-circular, and two are symmetrically arranged around the outer ring 422. A support structure 21 is also provided in the body 11. The two ECG electrode structures 41 are respectively arranged on both sides of the support structure 21. The support structure 21 can separate the two ECG electrode structures 41.

[0116] For example, an electronic device may have the function of detecting and obtaining an electrocardiogram (ECG), which requires the electronic device to have an ECG electrode structure 41 and an ECG conductive post structure on its casing.

[0117] For example, the body 11, which includes heat-conducting sheets and heat-conducting columns, can enable electronic devices to measure the temperature of the human body.

[0118] Different electronic devices have different functions, and the structure of the outer casing 1 of the electronic devices is also different. Therefore, the body 11 of the outer casing 1 of the electronic device is formed with one or more of the following according to the function it is to achieve: photoplethysmography light-blocking structure 42, photoplethysmography light-filtering structure, electrocardiogram electrode structure 41, electrocardiogram conductive pillar structure, heat-conducting sheet, heat-conducting pillar, and radio frequency antenna.

[0119] Figure 24 for Figure 1 Another structural diagram of the ontology, such as Figure 24 As shown, the first ring H is located at the center of the body 11, and the second ring I, the third ring J, and the fourth ring K are sequentially nested around the first ring H from the inside out. The first ring H is a solid cylindrical structure, while the second ring I, the third ring J, and the fourth ring K are all hollow tubular structures. The first ring H, the second ring I, the third ring J, and the fourth ring K can be made of different materials, or some of the materials can be the same. For example, the second ring I can be a light-blocking structure, or both the second ring I and the fourth ring K can be light-blocking structures, requiring that the refractive index of the second ring I and the fourth ring K is less than the refractive index of the first ring H and the third ring J. For example, Figure 24 As shown, the first ring H and the third ring J have the same refractive index, and the second ring I and the fourth ring K have the same refractive index. The refractive index of the second ring I is less than that of the first ring H. Of course, the refractive indices of the first ring H and the third ring J can be different, and the refractive indices of the second ring I and the fourth ring K can also be different. The key is to ensure that the refractive index of the second ring I is less than that of the first ring H, and that the refractive index of the second ring I is also less than that of the third ring J, thus achieving the light-blocking function of the second ring I and the fourth ring K.

[0120] Exemplarily, the second ring I and the fourth ring K can also be conductive materials, so that the second ring I and the fourth ring K can constitute conductive electrodes of the ECG; or the first ring H and the third ring J can also be conductive materials, so that the first ring H and the third ring J can also constitute conductive electrodes of the ECG.

[0121] In addition, any one of the first ring H, the second ring I, the third ring J and the fourth ring K can be a heat conduction sheet to provide a low-thermal-resistance heat conduction path from the skin to the internal sensor of the watch, and the heat conduction sheet and the ECG electrode can be simultaneously made on any one of the first ring H, the second ring I, the third ring J and the fourth ring K. In order to realize the PPG light isolation structure, exemplarily, the second ring I and the fourth ring K can constitute the conductive electrodes of the ECG, the first ring H and the third ring J can be used as the PPG transmission and receiving window, at this time, the second ring I and the fourth ring K can also be used as the light isolation structure; the first ring H and the third ring J constitute the conductive electrodes of the ECG, and the implementation is similar. The first ring H and the third ring J are used as the PPG transmission and receiving window, and can also be used as the ECG electrode at the same time, at this time, the second ring I and the fourth ring K are only used as the light isolation structure; conversely, the second ring I and the fourth ring K are used as the PPG transmission and receiving window, and can also be used as the ECG electrode, and the first ring H and the third ring J are only used as the light isolation structure.

[0122] In addition, the thickness of the body 11 can be 100 μm-200 μm, and the body 11 can be integrally attached to the inner surface of the watch bottom shell to form a light isolation structure, thereby replacing the use of a Fresnel film, avoiding the structure inside the watch bottom shell from being observed through the body 11, and improving the appearance aesthetics of the watch.

[0123] The preparation method of the existing electronic device shell 1 separately processes different human feature detection structures, so when the electronic device has multiple human feature detection functions, the preparation process of the electronic device shell 1 is long and complex, and the cost is high.

[0124] Therefore, an embodiment of the present application provides a preparation method of an electronic device shell 1, as shown in the figure, comprising the following steps: Figures 2-4 as shown in the figure, comprising the following steps:

[0125] Step S1: Preparing a first liquid glass substrate.

[0126] The glass substrate is the main material of the electronic device shell 1, and the glass substrate can be shaped into various material forms, such as liquid, solid, molten state, etc. In this embodiment, the glass substrate can be manufactured into a liquid state in advance to facilitate subsequent processing.

[0127] Step S2: Adding a material for realizing a human feature detection function or a device function in a set area of the first liquid glass substrate to form a composite material.

[0128] The electronic device can have the function of detecting the heart rate, electrocardio, body temperature, etc. of the human body, which requires the corresponding material on the electronic device shell 1 to assist in realizing the function, so the material for realizing the human feature detection function or the device function is added to the set area of the first liquid glass substrate to form a composite material to realize the above functions. Among them, the set area can be an area on the first liquid glass substrate for processing an area that can realize the human feature detection function or the device function. Such an area can be one or more, and the shape of such an area can also have multiple shapes, such as a rectangular shape, a square shape, a circular shape, a ring shape, a semi-ring shape, or an irregular shape, etc. so that the material used to realize the human feature detection function or the device function can form the above corresponding shape after forming.

[0129] Step S3: integrally process the composite material into a blank.

[0130] The function of the electronic device to measure the heart rate, electrocardio, body temperature, etc. of the human body also requires the functional material on the electronic device shell 1 to have a special structure to assist in realizing the function, so after adding the material for realizing the human feature detection function or the device function, the functional material is integrally formed with the first liquid glass substrate to form a blank, and the blank has a special structure required by the electronic device to detect the human feature. 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 shell 1, thereby reducing the production cycle of the electronic device shell 1 and reducing the production cost of the electronic device shell 1.

[0131] Among them, after the functional material and the first liquid glass substrate are formed into a whole blank, the blank can be cut to form a shell, and there is no need to perform post-processing on the material piece obtained after cutting, such as forming an ECG electrode by metal plating, coating light-shielding ink to form a PPG light-shielding structure, etc. Thus, the present embodiment can adopt an integrally processed and formed manner to simplify the production process of the electronic device shell 1, thereby reducing the production cycle of the electronic device shell 1 and reducing the production cost of the electronic device shell 1.

[0132] Step S4: cutting the blank to form the electronic device shell 1.

[0133] As shown in Figure 3 and Figure 4 , the formed blank can include at least one or several special structures formed by special materials. Multiple electronic device shells can be cut on the formed blank, so the process efficiency is high and the average production cycle of a single electronic device shell 1 is short. Among them, as shown in Figure 3As shown, after the glass liquid is shaped in the mold, the shape of the glass substrate 2 can be the same as that of the mold. The glass substrate 2 in this embodiment can be shaped as a rectangle, and of course can also be a square, a circle or other shapes.

[0134] In one glass substrate 2, there can be multiple regions of special structures formed by special materials, exemplarily as shown in Figure 3 As shown, the glass substrate 2 has nine special regions described above, and the nine special regions can be distributed in an array, and each special region can include one or more different special materials, for example, each special region can only include materials for detecting PPG function, can only include materials for detecting ECG function, can include materials for detecting PPG and ECG functions at the same time, or can include materials for detecting other human characteristics, such as heat-conducting materials, etc. The above nine regions can be cut to form the housing of the watch, so that multiple regions with multiple special structures formed by special materials can be realized at the same time in the process of shaping the glass substrate 2 once, simplifying the process and improving the production efficiency.

[0135] Therefore, by using the preparation method of the electronic device housing 1 provided in the present application, the blank can have multiple functional structures 4 for human characteristic detection in the process of shaping the first liquid glass substrate once, solving the problem of complex manufacturing process of the electronic device housing 1, reducing the production cost of the electronic device housing 1, and shortening the production cycle of the electronic device housing 1. The functional structure is a part of structure that needs to be embedded into the first liquid glass substrate in a certain shape and volume.

[0136] In addition, in the process of shaping the first liquid glass substrate, a support structure 21 can also be added to the first liquid glass substrate, which can realize the series connection of each of the above special structures in the blank, improve the strength of the blank, provide support for the blank, prevent the blank from breaking during cutting, and at the same time improve the strength of the electronic device housing 1 cut from the blank, so that it is not easy to be damaged.

[0137] In a specific embodiment, as shown in Figure 5 For step S2: adding materials for realizing human characteristic detection function or device function to the set region of the first liquid glass substrate to form a composite material, specifically including:

[0138] Step A1: Preparing a functional structure 4 for realizing human characteristic detection function or device function.

[0139] The preformed functional structure 4 is configured to have a function of assisting the electronic device to realize the human feature detection function or the device function. The functional structure 4 can be a structure having a physical shape, i.e., a part of structure to be embedded into the first liquid glass substrate is manufactured in a certain shape and volume.

[0140] Step A2: embedding the functional structure 4 into the first glass substrate at a predetermined region.

[0141] During the process of forming the glass from liquid to solid, the functional structure 4 is formed into a glass composite structure together with the glass liquid. For example, in the process of manufacturing the float glass, the functional structure 4 is put into the forming equipment of the glass, for example, at a predetermined region in the tin bath. For another example, in the process of glass drawing, the functional structure 4 is embedded. For another example, the functional structure 4 is previously placed in a mold, and the glass liquid is poured into the mold to form a glass composite material with the embedded functional structure 4 by rolling. For another example, the functional structure 4 and the glass liquid are continuously rolled into a composite glass strip by a calender. Thus, through the manufacturing process of the electronic device shell 1, the blank of the electronic device shell 1 can be provided with the functional structure 4 required for the human feature detection function or the device function through one-time processing, and the electronic device shells 1 obtained after cutting the blank are simple in process, thereby reducing the production cost and shortening the production cycle of the electronic device shell 1. In addition, the electronic device shells 1 obtained after cutting can be further polished and then subjected to secondary processing to obtain the final shell 1 product.

[0142] In a specific embodiment, as shown in Figure 3 、 Figure 4 and Figure 6 , for Step A1: preforming the material for realizing the human feature detection function or the device function into the functional structure 4, specifically includes:

[0143] Step B1: preforming the second liquid glass substrate.

[0144] Step B2: adding the microcrystal seeds for realizing the human feature detection function or the device function into the second liquid glass substrate.

[0145] Step B3: processing the second liquid glass substrate with the added microcrystal seeds to generate a glass matrix.

[0146] Step B4: reprocessing the glass matrix to grow the microcrystal seeds to form the functional structure 4 for realizing the human feature detection function or the device function.

[0147] The second liquid glass substrate can be a part of the first liquid glass substrate, i.e., a part of the first liquid glass substrate is extracted as the second liquid glass substrate after the first liquid glass substrate is prepared. Of course, the second liquid glass substrate can also be a glass substrate prepared separately, which can be prepared in two times with the first liquid glass substrate. The microcrystal seeds capable of achieving the human feature detection function or the device function are added to the second liquid glass substrate to form a glass substrate, and the glass substrate is reprocessed to make the microcrystal seeds capable of achieving the human feature detection function or the device function crystallize according to a set structure to form the functional structure 4. The reprocessing of the glass substrate can promote the crystallization of the microcrystal seeds and reduce the time required for forming the functional structure 4. For example, as shown in Figure 4 the microcrystal seeds can be crystallized to form the photoplethysmogram light barrier structure 42 or the electrocardiogram electrode structure 41, or the photoplethysmogram light barrier structure 42 and the electrocardiogram electrode structure 41 can be embedded in the set regions, respectively.

[0148] In a specific embodiment, as shown in Figure 3 and Figure 7 for step S2: adding a material for achieving the human feature detection function or the device function to the set region of the first liquid glass substrate to form a composite material, specifically including:

[0149] Step C1: incorporating microcrystal seeds for achieving the human feature detection function or the device function into the set region of the first liquid glass substrate.

[0150] Step C2: processing the first liquid glass substrate with the incorporated microcrystal seeds to generate the glass substrate 2.

[0151] Step C3: reprocessing the glass substrate 2 to make the microcrystal seeds crystallize and form the functional structure 4 for achieving the human feature detection function or the device function.

[0152] The glass substrate is preformed into a liquid state by heating, and the obtained glass liquid is filled into a specific mold which can define the shape of the glass liquid. Microcrystal seeds capable of realizing the function of human feature detection or equipment are added to the set region of the glass liquid in the mold, and a glass substrate 2 is formed. The glass substrate 2 is subjected to controllable processing to make the microcrystal seeds capable of realizing the function of human feature detection or equipment grow, so that a functional structure 4 is formed in the set region of the glass substrate 2. The set region can be the region which is expected to be cut into the electronic equipment shell 1. For example, the realization of ECG function requires electrode structure, so the set region in the glass liquid is doped with microcrystal seeds with high conductivity and low half-cell potential formed with skin tissue in a surface manner, such as AgCl, Ni, etc. Through controllable processing, the ions with high conductivity are crystallized on the microcrystal seeds to form electrode structure penetrating through the glass substrate 2. For another example, the realization of ECG function requires conductive column, so the set region in the glass liquid is doped with microcrystal seeds with high conductivity in thickness, such as Au, Cu, AgCl, or a combination of two or more thereof. For another example, for human temperature measurement, the set region in the glass liquid can be doped with microcrystal seeds with high conductivity in a surface manner, such as Cu.

[0153] Therefore, through the process method, the process is simple, so that the production cost of the electronic equipment shell 1 is low, and the production cycle is short.

[0154] The set region can include a first region for doping microcrystal seeds for realizing ECG detection function. The first region can have a set position and shape, and the microcrystal seeds for realizing ECG detection function are only doped into the first region, and the regions other than the first region are not doped with the microcrystal seeds for realizing ECG detection function, so that the microcrystal seeds can only grow into functional structure for detecting user ECG function in the first region.

[0155] Of course, the set region can also include a second region for doping microcrystal seeds for realizing PPG detection function. The second region can also have a set position and shape, and the microcrystal seeds for realizing PPG detection function are only doped into the second region, and the regions other than the second region are not doped with the microcrystal seeds for realizing PPG detection function, so that the microcrystal seeds can only grow into functional structure for detecting user PPG function in the second region.

[0156] The first region and the second region can be located in the body 11, so that the body has ECG and PPG detection functions.

[0157] In a specific embodiment, for step C3: reprocessing the glass substrate 2, specifically includes one or more of the following: heat treatment, laser treatment or ion beam treatment of the glass substrate 2. These processing methods can all promote the crystallization of ions for realizing the human feature detection function or the device function on the microcrystal seeds, and accelerate the crystallization speed and shorten the processing time. In a specific operation, only one of the processes can be used for processing, or two or three of them can be combined for processing. For example, the glass substrate 2 can be simultaneously subjected to heat treatment and laser treatment, or laser treatment and ion beam treatment, or heat treatment, laser treatment and ion beam treatment, so as to facilitate the ion implantation to be deeper, the response time to be faster and the efficiency to be improved.

[0158] In a specific embodiment, before the microcrystal seeds for realizing the human feature detection function or the device function are doped into the set region of the first liquid glass substrate, the method further includes: masking the region outside the set region on the first liquid glass substrate.

[0159] Masking the region outside the set region on the first liquid glass substrate can avoid adding the microcrystal seeds to the region that does not need to be doped during the doping. The masking can make the operation of doping the microcrystal seeds more accurate, faster, convenient and efficient.

[0160] In addition, multiple masking operations can be used to respectively realize the doping of microcrystal seeds with multiple different functions. For example, for preparing the electronic device shell 1 with ECG and PPG functions, a first masking operation can be performed to dope the microcrystal seeds capable of realizing one of ECG or PPG. Then, another masking operation can be performed to dope the microcrystal seeds capable of realizing the other of ECG or PPG, so as to respectively ensure the doping accuracy of the microcrystal seeds capable of realizing ECG or PPG.

[0161] In a specific embodiment, as shown in FIG. 1, after step S1, the method further includes: Figures 8-11

[0162] Step D1: processing the first liquid glass substrate into a columnar rod body 3.

[0163] According to the shape of the electronic device shell 1, the glass substrate can be preformed into a columnar rod body 3 with a circular, square or other cross-sectional shape, so as to facilitate subsequent processing.

[0164] After step S2, the method further includes:

[0165] Step D2: providing at least one preformed hole 31 in the substrate of the columnar rod body.

[0166] ​The preformed hole 31 can be multiple, and the shape of the cross section of the preformed hole 31 along the length direction of the columnar rod body 3 is the same as the shape of the functional structure 4.

[0167] Step D3: Preform the material for realizing the human feature detection function or the device function into the functional structure 4.

[0168] Step D4: Embed the functional structure 4 in the preformed hole 31.

[0169] Since the shape of the cross section of the preformed hole 31 along the length direction of the columnar rod body 3 is the same as the shape of the functional structure 4, the functional structure 4 can be embedded in the preformed hole 31.

[0170] Step D5: Melt the base material of the columnar rod body and / or the functional structure 4 by a hot working process.

[0171] The melting point of the glass base material can be higher than the melting point of the functional structure 4, and when the temperature rises to the melting point of the functional structure 4, the functional structure 4 can be melted and fused with the glass base material. The melting point of the glass base material can be lower than the melting point of the functional structure 4, and when the temperature rises to the melting point of the glass base material, the glass base material can be melted and fused with the functional structure 4. Of course, the temperature can also rise to be higher than the melting points of the glass base material and the functional structure 4, so that the glass base material and the functional structure 4 are both melted to realize the fusion of the two.

[0172] After fusion, the glass base material and the functional structure 4 can be solidified by a solidification process to form a columnar blank for preparing the electronic device shell 1, as shown in Figure 10 , and cutting along the cutting position at the dotted line as shown in Figure 10 , to obtain the electronic device shell 1.

[0173] In the above preparation method of the electronic device shell 1, by opening the preformed hole 31 on the glass base material, and preforming the material for realizing the human feature detection function or the device function into the functional structure 4 and then installing it in the preformed hole 31, when the electronic device has multiple human feature detection functions or device functions, the electronic device shell 1 does not need to be processed multiple times, thereby simplifying the production process of the electronic device shell 1, and thus reducing the production cost and shortening the production cycle of the electronic device shell 1.

[0174] In a specific embodiment, the functional structure 4 is one or a combination of two or more of a photoplethysmogram light barrier structure 42, a photoplethysmogram filter structure, an electrocardiogram electrode structure 41, an electrocardiogram conductive column structure, a heat conduction sheet, a heat conduction column, and a radio frequency antenna.

[0175] In the embodiment, according to the function of the electronic device, one or more than two combined structures of the photoelectric volume diagram light isolation structure 42, the photoelectric volume diagram light filter structure, the electrocardiogram electrode structure 41, the electrocardiogram conductive column structure, the heat conduction sheet, the heat conduction column and the radio frequency antenna can be formed on the shell 1 of the electronic device by the preparation method of the electronic device shell 1.

[0176] In a specific embodiment, as shown in Figure 12 and Figure 13 After step S1, the method further includes:

[0177] Step E1: process the first liquid glass substrate into a plurality of first columnar rods 5. The first columnar rods 5 can be rods of different diameters, as shown in Figure 13 The cross-sectional line is a dotted circular area, which is a first columnar rod. The first columnar rod located at the center position has the largest diameter and has higher structural strength. A circle of smaller diameter first columnar rods is wrapped around the periphery of the first columnar rod located at the center position. A circle of light isolation rods 61 is wrapped around the periphery of the smaller diameter first columnar rods. At least one circle of first columnar rods can be wrapped around the periphery of the light isolation rods 61. The periphery of the at least one circle of first columnar rods can be partially wrapped with a conductive rod 62. A circle of first columnar rods 5 can be wrapped around the periphery of the conductive rod 62. In addition, as shown in Figure 13 In the arrangement of the rods, there are also some tubular rods 9, which are hollow structures. After the fusion of the rods, the tubular rods 9 can form a through hole for absorbing user body fluid.

[0178] After step S2, the method further includes:

[0179] Step E2: preform the material for realizing the human feature detection function or the device function into a plurality of second columnar rods 6.

[0180] The second columnar rods 6 can include rod materials for realizing different human feature detection functions, for example, the second columnar rods include one or more than two combinations of light filter rods, light isolation rods, conductive rods, and heat conduction rods. For example, as shown in Figure 13 The second columnar rods 6 can include light isolation rods 61 and conductive rods 62.

[0181] It should be noted that the first columnar rods 5 can be light transmission rods, and some of the second columnar rods 6 can be light filter rods. The light transmission rods and the light filter rods can be materials with the same refractive index, or materials with gradually changing refractive index, or materials with step refractive index. The structure of the first columnar rods 5 and the second columnar rods 6 can be the same. For the sake of convenience, the structure of the first columnar rods 5 is taken as an example for illustration.

[0182] Figure 21 As a schematic diagram of a first columnar rod and its corresponding refractive index, in a specific embodiment, as shown in Figure 21 , the overall appearance of the first columnar rod 5 is a cylinder (see Figure 21 the right drawing), with a diameter of 2r. Along the diameter direction of the cylinder (see Figure 21 the longitudinal axis direction in the left drawing, O is the position of the central axis), the refractive index of the first columnar rod 5 is n1 (see Figure 21 the horizontal axis direction in the left drawing), that is, the first columnar rod 5 has a uniform refractive index along the diameter direction, which is represented by a vertical straight line n1 in the left drawing of Figure 21 .

[0183] In addition, in another specific embodiment, as shown in Figure 22 , the overall appearance of the first columnar rod 5 is also a cylinder (see Figure 22 the right drawing), with a diameter of 2r. Along the diameter direction of the cylinder (see Figure 22 the longitudinal axis direction in the left drawing, O is the position of the central axis), the refractive index of the first columnar rod 5 gradually increases with the gradual decrease of the radius, that is, the first columnar rod 5 has a gradually changing refractive index from n2 to n1 along the diameter direction (see Figure 22 the horizontal axis direction in the left drawing), where n1>n2, which is represented by an arc curve 51 in the left drawing of Figure 22 . That is, the refractive index of the first columnar rod 5 gradually increases from the edge to the central axis position, which is beneficial to confine the light to the central region of the rod and play a role in collimation.

[0184] Figure 23 As another schematic diagram of a first columnar rod and its corresponding refractive index, as shown in Figure 23 , the first columnar rod 5 includes a first segment 52 and a second segment 53, both of which are cylinders (see Figure 23 the right drawing), the diameter of the first segment 52 is 2r1, the diameter of the second segment 53 is 2r2, and the diameter 2r1 of the first segment 52 is greater than the diameter 2r2 of the second segment 53. Referring to Figure 23 the left drawing, the longitudinal axis direction in the drawing is the diameter direction of the first segment 52 and the second segment 53, and the horizontal axis in the drawing represents the refractive index. The first columnar rod 5 has a first refractive index n1 in the diameter direction of the second segment 53, and a second refractive index n2 in the diameter direction from the outer periphery of the first segment 52 to the outer periphery of the second segment 53, n1>n2, which is represented by an arc curve 51 in the left drawing of Figure 23In the left figure, the first refractive index n1 and the second refractive index n2 are embodied as two parallel vertical straight lines. That is, the second section 53 close to the central axis position has a larger refractive index relative to the first section 52, which is also conducive to confining the light to the central region of the rod, playing a role of collimation.

[0185] Exemplarily, the refractive index inside or between the light-transmitting rod bodies is formed to be variable, which can be specifically implemented as a first columnar rod body with a gradually changing refractive index as shown in Figure 23 , or a first columnar rod body with a stepped refractive index as shown in Figure 24 , or the adjacent rod bodies have different refractive indexes, which are all conducive to presenting the beautiful effect of the haze of the Fresnel film in appearance.

[0186] Step E3: arranging a plurality of the first columnar rod bodies 5 and a plurality of the second columnar rod bodies 6 in a set order.

[0187] Step E4: melting the first columnar rod bodies 5 and / or the second columnar rod bodies 6 by a hot working process to fuse the first columnar rod bodies 5 and the second columnar rod bodies 6. The melting point of the first columnar rod bodies 5 can be higher than the melting point of the second columnar rod bodies 6, of course, the melting point of the first columnar rod bodies 5 can also be lower than the melting point of the second columnar rod bodies 6, when the heating temperature rises to the lower melting point of the first columnar rod bodies 5 and the second columnar rod bodies 6, the rod with the lower melting point melts, thereby realizing the fusion of the first columnar rod bodies 5 and the second columnar rod bodies 6. Of course, the temperature can also be raised to be greater than the melting points of the first columnar rod bodies 5 and the second columnar rod bodies 6, so that the first columnar rod bodies 5 and the second columnar rod bodies 6 are both melted, and the fusion of the two can also be realized.

[0188] After fusion, the first columnar rod bodies 5 and the second columnar rod bodies 6 can be solidified by a solidification process to form a columnar blank for preparing the electronic device shell 1, as shown in Figure 15 , and cut along the height direction perpendicular to the columnar blank to obtain the electronic device shell 1.

[0189] In the preparation method of the electronic device shell 1, by arranging the first columnar rod bodies 5 and the second columnar rod bodies 6, a functional structure 4 of any shape can be obtained to realize the detection of human features by the electronic device, such as being arranged into a circle, a square, a rectangle, an ellipse, etc. The preparation method is simple, thereby making the production cost of the electronic device shell 1 low and the production cycle short.

[0190] In a specific embodiment, as shown in Figures 14-16 , after step S1, the method further comprises:

[0191] Step F1: pre-preparing the first liquid glass substrate into a plurality of third columnar rod bodies 7.

[0192] After step S2, the method further comprises:

[0193] Step F2: Preparing a plurality of fourth columnar rods 8 for implementing the human feature detection function or the device function.

[0194] Step F3: Preparing at least one hollow tubular rod 9 with a melting point higher than the melting point of the glass substrate and the melting point of the material for implementing the human feature detection function or the device function.

[0195] Step F4: Arranging the plurality of third columnar rods 7, the plurality of fourth columnar rods 8, and the at least one tubular rod 9 in a set order.

[0196] Step F5: Melting the third columnar rods 7 and / or the fourth columnar rods 8 by a hot working process to fuse the third columnar rods 7, the fourth columnar rods 8, and the tubular rod 9, and form a through hole 12 at the tubular rod 9, as shown in Figures 15-16 .

[0197] In the preparation method of the electronic device shell 1, the fourth columnar rods 8 enable the electronic device shell 1 to have a functional structure 4 to meet the needs of the electronic device for human feature detection, and the melting point of the tubular rod 9 is higher than that of the third columnar rods 7 and the fourth columnar rods 8, so that after the third columnar rods 7 and the fourth columnar rods 8 are melted, the tubular rod 9 is not melted, so that the third columnar rods 7, the fourth columnar rods 8, and the tubular rod 9 are fused, and a through hole 12 is formed in the hollow part of the tubular rod 9. The through hole 12 can be used for measuring human features and for drug delivery to the skin.

[0198] In a specific embodiment, as shown in Figure 15 , the plurality of fourth columnar rods 8 include one or a combination of more than two of a light filtering rod, a light blocking rod 81, a conductive rod 82, and a heat conducting rod.

[0199] In this embodiment, the light filtering rod and the light blocking rod 81 are processed to form a photoplethysmogram light filtering structure and a photoplethysmogram light blocking structure 42, thereby realizing the function of the electronic device to measure the heart rate of the human body by PPG. The conductive rod 82 is processed to form an electrocardiogram electrode structure 41 and an electrocardiogram conductive column structure, thereby realizing the function of the electronic device to measure ECG. The heat conducting rod is processed to form a heat conducting sheet or a heat conducting column, thereby realizing the function of the electronic device to measure the body temperature of the human body. According to the actual functional requirements of the electronic device, the plurality of fourth columnar rods 8 include one or a combination of more than two of a light filtering rod, a light blocking rod 81, a conductive rod 82, and a heat conducting rod, for example, when the electronic device has the functions of measuring the heart rate and body temperature of the human body, the fourth columnar rods 8 should include a light filtering rod, a light blocking rod 81, and a heat conducting rod.

[0200] In a specific embodiment, as shown in Figures 17-19 The plurality of fourth columnar rods 8 include a plurality of light isolation rods 81, which have a rectangular, trapezoidal or parallelogram shape in the length direction.

[0201] In the embodiment, as shown in Figures 16-18 According to the different wavelengths of the measuring light selected by the PPG and the different structures of the electronic device, the photoelectric plethysmogram light isolation structure 42 formed by the light isolation rods 81 has different cross-sectional shapes in the length direction. In order to achieve the best emission and reception effect of the measuring light, the photoelectric plethysmogram light isolation structure 42 formed by the light isolation rods 81 can have a rectangular, trapezoidal or parallelogram shape in the length direction.

[0202] In a specific embodiment, as shown in Figure 16 The plurality of light isolation rods 81 are arranged to form a closed circular ring, an ellipse or a partially open ring.

[0203] In the embodiment, as shown in Figure 15 The shape of the light isolation rods is only required to satisfy the light isolation between the emission window and the receiving window, and thus the shape of the light isolation rods can be various, such as a closed circular ring, an ellipse or a partially open ring.

[0204] In a specific embodiment, the substrate can be glass or ceramic, and can also be an organic material, such as PC, polyester, etc.

[0205] With the fashionization of electronic devices, people no longer satisfy with the electronic devices with metal shells 1. Compared with the metal shell 1, the glass or ceramic shell 1 has a better hand feeling and is more solid and less likely to be scratched, which can provide consumers with a novel experience. At the same time, compared with the metal shell 1, the ceramic or glass has a smaller influence on the antenna sending and receiving signals, and the signal of the electronic device is also better. When the substrate is ceramic, the ceramic is usually in a powder form, and a material having a human feature detection function or realizing a device function can be added therein. The powder ceramic can be sintered into a structure having a certain shape, such as a rod having different diameters, through a sintering process. The preformed hole can be formed in the rod ceramic during the sintering process, or the hole can be punched after the rod ceramic is sintered through a punching process. For the electronic device shell 1 provided in the embodiment, as shown in Figure 20 The body 11 has a through hole 12.

[0206] In the embodiment, as shown in Figure 15As shown, the body 11 of the electronic device shell 1 is formed with through holes 12, which can be used for measuring human characteristics and for skin drug delivery. Specifically, the drug delivery mechanism is arranged inside the electronic device. According to the doctor's prescription or the set program, the drug delivery mechanism injects the drug into the through hole 12, and then the drug is delivered to the skin through the through hole 12. At the same time, the volume of a single through hole 12 is small, but the number of through holes 12 is large, and the total area of the skin contact is large, so the skin absorption effect of the drug is good.

[0207] In a specific embodiment, the electronic device further comprises a biochemical sensor and an adsorption device. The biochemical sensor and the adsorption device are arranged in the body 11. The adsorption device is used to adsorb the body fluid of the user, and the biochemical sensor is used to detect the biochemical parameter value of the body fluid.

[0208] In this embodiment, one end of the through hole 12 is in contact with the skin of the human body, and the other end is connected with the adsorption device. The adsorption device adsorbs the sweat or interstitial fluid on the surface of the skin of the human body through the through hole 12. The biochemical sensor inside the electronic device can analyze the sweat or interstitial fluid, thereby monitoring the health condition of the wearer, widening the function of the electronic device, and improving the user experience.

[0209] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
