Description

Technical Field

[0001] The present application relates to the field of electronic devices, and in particular to wearable electronic devices. Background Art

[0002] The shells of existing wearable electronic devices such as watches and bracelets are usually made of plastic and metal materials. Plastic materials lack texture, while metal materials have a high density and are therefore heavy. Therefore, it is desirable to find a material with good texture and low density to replace the above-mentioned plastic and metal materials. After research, it was found that carbon fiber materials have a low density (about 1.8 g / cm3) and high strength, and their unique texture makes them have a good texture. Therefore, carbon fiber materials are gradually being used more and more as the main material for the shells as an alternative material that can be used in wearable electronic devices.

[0003] Some wearable electronic devices, represented by smart watches, typically have antennas. These wearable electronic devices all form antennas through their housings. Antennas can be divided into Bluetooth antennas, GPS (Navigation Satellite Timing And Ranging Global Positioning System) antennas, WIFI (Wireless Fidelity) antennas, 4G / 5G communication antennas, etc. according to different bands. When the above-mentioned wearable electronic devices use plastic materials to make the housing, the antenna is formed by metallizing the surface of the housing. When the above-mentioned wearable electronic devices use metal materials to make the housing, the antenna is formed by electrically connecting the housing to the circuit board assembly. However, when the above-mentioned wearable electronic devices use carbon fiber materials to make the housing, in addition to the carbon fiber material, the housing may also contain pre-impregnated plastic and a certain proportion of glass fiber. Since the carbon fiber material itself is a conductor, while the pre-impregnated plastic and glass fiber are non-conductors, the housing made in this way is a discontinuous conductor structure that cannot conduct well as part of the antenna. Instead, it forms a shielding housing, affecting the radiation performance of the antenna. Summary of the Invention

[0084] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0085] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0086] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0087] It should be noted that the “annular” described in this application includes but is not limited to various annular shapes such as a circular ring, a square ring, and an elliptical ring.

[0088] The structure of the wearable electronic device according to each embodiment of the present application is described below with reference to the accompanying drawings.

[0089] (Structure of a Wearable Electronic Device According to the First Embodiment of the Present Application)

[0090] like Figure 1A to Figure 1B As shown, the wearable electronic device according to the first embodiment of the present application includes an assembled housing 1, a metal inner shell 2, a circuit board assembly 3, a rear shell 4, and a screen assembly 5. The housing 1, the rear shell 4, and the screen assembly 5 surround and form an installation space, and the metal inner shell 2 and the circuit board assembly 3 are located in the installation space.

[0091] Specifically, in this embodiment, Figure 1A As shown, the housing 1 includes an annular housing base 11 and a housing extension 12 formed integrally with the housing base 11. Two pairs of housing extensions 12 extend from the housing base 11 toward both sides, respectively, to cover the inner liner extension 22 of the metal liner 2. The housing base 11 has an inner circumferential surface 11i extending continuously along its circumference. The inner circumferential surface 11i of the housing base 11 serves as the inner surface of the housing 1. Figure 1B As shown, after the wearable electronic device is assembled, the inner circumferential surface 11 i of the housing base 11 faces the installation space and is completely covered, and the user cannot see the inner circumferential surface 11 i.

[0092] The shell 1 is mainly made of carbon fiber material. In order to make the shell 1 itself constitute a part of the antenna, such as Figure 1A and Figure 1BAs shown, the housing 1 includes a conductive layer 13 disposed on the inner circumferential surface 11i of the housing base 11. The conductive layer 13 electrically connects the dispersed carbon fiber material within the housing 1, thereby enhancing the conductivity of the entire housing 1. In this embodiment, the conductive layer 13 may contain a metal component. Specifically, the conductive layer 13 may be a non-transparent film formed by electroplating. In this case, the conductive layer 13 may optionally contain at least one of copper, nickel, chromium, zinc, iron, gold, and silver. The conductive layer 13 may have a multilayer structure. The multilayer structure may be a multilayer structure in which one material layer and another material layer are alternately stacked, or a multilayer structure in which one material layer is coated with another material layer. Specifically, the multilayer structure may include a copper layer and a gold layer, a titanium layer and an aluminum layer, or a nickel layer and a chromium layer. The conductive layer 13 may also be a transparent film formed by electroplating. In this case, the conductive layer 13 may optionally contain indium tin oxide. In an optional embodiment, the conductive layer 13 may be a ceramic conductive film such as titanium carbide, titanium nitride, or titanium boride. Regardless of the material used to make the conductive layer 13, in this embodiment, the conductive layer 13 extends continuously along the circumference of the inner circumference 11i of the shell substrate 11, covering the entire inner circumference 11i. In addition to electrically connecting the carbon fibers dispersed within the shell 1 into a single conductor, the conductive layer 13 also electrically connects the shell 1 to the metal liner 2 via the conductive layer 13.

[0093] Furthermore, in this embodiment, Figure 1A and Figure 1B As shown, the metal liner 2 is made of or mainly made of metal material. The metal liner 2 is located between the outer shell 1 and the circuit board assembly 3. The metal liner 2 is not only electrically connected to the outer shell 1 but also electrically connected to the circuit board assembly 3. The metal liner 2 includes an annular liner base 21 and an inner liner extension 22 formed as a whole with the liner base 21. When the wearable electronic device is installed, the liner base 21 is located radially inward of the outer shell base 11, and the liner extension 22 is inserted into the outer shell extension 12. The metal liner 2 is mainly used to improve the dustproof and waterproof performance and structural strength of the wearable electronic device.

[0094] like Figure 1A and 1B As shown, in order to fix the outer shell 1 and the metal liner 2 to each other and achieve electrical connection, the wearable electronic device includes a conductive adhesive 23. The conductive adhesive 23 is located between the inner circumference 11i of the outer shell 1 and the outer circumference of the metal liner 2. The conductive adhesive 23 contacts the conductive layer 13 on the inner circumference 11i of the outer shell 1, so that the outer shell 1 and the metal liner 2 are fixed together through the conductive adhesive 23 and are also electrically connected through the conductive adhesive 23. This application does not have any restrictions on the shape and arrangement of the conductive adhesive 23, as long as the conductive adhesive 23 can achieve the above-mentioned effects. Specifically, although in Figure 1AThe conductive adhesive 23 is shown as being arranged on the metal liner 2 in a shape of a roughly circular arc, but is not limited thereto. The shape of the conductive adhesive 23 can be set to other shapes as needed and can be arranged at different locations of the metal liner 2. In addition, the present application does not impose any restrictions on the base material and conductive components of the conductive adhesive 23, as long as the conductive adhesive 23 can achieve the above-mentioned functions. Specifically, different bases can be selected according to different curing conditions, and the bases can include various plastics, dispersants, and additives. The conductive components of the conductive adhesive 23 can be conductive materials such as silver powder, gold powder, copper powder, aluminum powder, zinc powder, nickel powder, carbon powder, and graphite. In addition, the conductive adhesive 23 can be in the form of a paste, a slurry, or a conductive tape. In an optional solution, the conductive adhesive 23 can be replaced with a conductive cloth, which is located between the outer shell 1 and the metal liner 2. The outer shell 1 and the metal liner 2 are fixed together by the conductive cloth and are electrically connected at the same time. In addition, the metal liner 2 can be electrically connected to the corresponding conductive parts (such as traces) of the circuit board assembly 3 through connecting columns, etc.

[0095] Furthermore, in this embodiment, Figure 1A As shown, the circuit board assembly 3 and the rear shell 4 are integrated together, and the circuit board assembly 3 is located in the rear shell 4. Figure 1B The lower part of the housing 1 is fixed together with the housing 1. Specifically, the housing 1 and the rear housing 4 can be connected together by snapping or connecting members such as screws.

[0096] Furthermore, in this embodiment, Figure 1A As shown, the screen assembly 5 includes a display unit 51. The display unit 51 displays information to the user after the wearable electronic device is assembled. The display unit 51 can also have the function of inputting information, so that the user can interact with the wearable electronic device through the display unit 51. Figure 1B The upper portion of the housing 1 is fixed together. Specifically, the housing 1 and the screen assembly 5 can be connected together by snapping, bonding or connecting members such as screws.

[0097] By employing the above technical solution, the conductive layer 13 provided on the inner surface of the outer shell 1 forms the entire outer shell 1, which is composed of carbon fibers, into a single conductor. Furthermore, the metal liner 2 is bonded to the outer shell 1 using conductive adhesive 23 or conductive fabric. The conductive adhesive 23 and conductive fabric electrically connect the outer shell 1, which is provided with the conductive layer 13, to the metal liner 2. The metal liner 2 is also electrically connected to the circuit board assembly 3. In this way, the outer shell 1 becomes part of the antenna of the wearable electronic device, increasing the antenna's efficiency.

[0098] The structure of a wearable electronic device according to a second embodiment of the present application is described below.

[0099] (Structure of a Wearable Electronic Device According to a Second Embodiment of the Present Application)

[0100] The structure of the wearable electronic device according to the second embodiment of the present application is basically the same as the structure of the wearable electronic device according to the first embodiment of the present application. The following mainly describes the differences between the two.

[0101] In the first embodiment, the conductive adhesive 23 and the conductive cloth are used to fix and electrically connect the outer shell 1 and the metal inner shell 2, thereby ensuring reliable conduction between the outer shell 1 and the metal inner shell 2 under various conditions such as long-term use or immersion in body fluids. In this embodiment, in order to further ensure the conduction between the outer shell 1 and the metal inner shell 2, as shown in FIG. Figure 2A and Figure 2B As shown, the wearable electronic device further includes a first elastic member 24, which is located between the housing 1 and the metal liner 2. Figure 2B After the wearable electronic device shown is installed, the first elastic member 24 is in a compressed state, always applying elastic force to the shell 1 and the metal liner 2, thereby further ensuring that the shell 1 and the metal liner 2 form a stable and reliable electrical connection via the first elastic member.

[0102] In this embodiment, if Figures 2A to 2C As shown, the first elastic member 24 is formed in the shape of a trident. Specifically, the first elastic member 24 comprises a first body 241 and a first spring clip 242. The first body 241 is in the shape of a double-dent and is formed in a sheet-like shape. A first mounting recess 21c is formed on the outer circumference of the metal liner 2 to accommodate and mount the first body 241. The first body 241 is located within the first mounting recess 21c and can be secured to the metal liner 2 by assembly methods such as spot welding, bonding, or snap fastening. One end of the first spring clip 242 is connected to the first body 241. The first spring clip 242 is located between the two prongs of the double-dent of the first body 241 and extends obliquely toward the outer shell 1, such that the other end of the first spring clip 242 is tilted relative to the first body 241 to abut against the conductive layer 13 on the inner circumferential surface 11i of the outer shell 1. In other words, the first body 241 is roughly U-shaped, with the first spring clip 242 extending from the bottom of the U between the two legs and tilted relative to the first body 241. The entire first elastic member 24 is formed into a substantially W-shape, or as Figure 2CThe user-visible M shape is shown. In an optional solution, the first elastic member 24 may include more than two first spring pieces. In this way, by adopting the first elastic member 24 of the above structure, the outer shell 1 can be stably electrically connected to the metal inner liner 2 via the conductive layer 13 and the first elastic member 24. Moreover, the first elastic member 24 is easy to assemble and occupies less space, has a simple structure and is conducive to mass production. Furthermore, in other optional solutions, conductive elastic members of other shapes such as cylindrical coil springs, conical coil springs, etc. can be selected, or conductive elastic members formed by the elasticity of the material itself can be selected to replace the above-mentioned first elastic member 24. In other words, the present application does not impose any special restrictions on the structure and material of the elastic member.

[0103] In addition, in conjunction with the first elastic member 24, more types of adhesives can be selected between the outer shell 1 and the metal liner 2. The adhesive can be the various conductive adhesives described in the first embodiment, or various structural adhesives, including silicone-based adhesives, epoxy-based adhesives, hot-melt adhesive series adhesives, and two-liquid mixed hardening adhesives of two or more composite components.

[0104] In addition, in an optional solution, in the axial direction A of the shell 1, the thickness (or height) of the shell 1 is approximately the same as the thickness (or height) of the metal liner 2; or the thickness of the shell 1 is slightly smaller than the thickness of the metal liner 2, so that after the wearable electronic device is assembled, a portion of the metal liner 2 (for example, a portion with an axial thickness of 0.3 mm) is exposed from the shell 1, which can improve the antenna gain of the wearable electronic device.

[0105] By adopting the above solution, compared with the first embodiment, the provision of the first elastic member 24 can help improve the electrical connection between the outer shell 1 and the metal inner shell 2 .

[0106] The structure of a wearable electronic device according to a third embodiment of the present application is described below.

[0107] (Structure of a Wearable Electronic Device According to a Third Embodiment of the Present Application)

[0108] The structure of the wearable electronic device according to the third embodiment of the present application is basically the same as the structure of the wearable electronic device according to the first embodiment of the present application and the structure of the wearable electronic device according to the second embodiment of the present application. The following mainly describes the differences between the two.

[0109] In the first and second embodiments above, the metal liner 2 is mainly used to improve the dustproof and waterproof performance and structural strength of the wearable electronic device. However, the metal liner 2 requires a lot of machining, which will increase the cost of the entire wearable electronic device. In addition, the metal liner 2 also weakens the lightweight feature brought by the shell 1 mainly made of carbon fiber. Based on the above situation, in this embodiment, if Figure 3A and Figure 3B As shown, the wearable electronic device includes a plastic liner 2' instead of the metal liner 2, and the plastic liner 2' is made of a non-conductive plastic material, and the plastic material can be epoxy plastic, polyimide, phenolic plastic, etc. The plastic liner 2' can be formed by injection molding. In this way, the shape of the plastic liner 2' can be formed in the mold, thereby saving a lot of mechanical processing, and the plastic liner 2' can also enhance the lightweight characteristics brought by the shell 1 mainly made of carbon fiber. In addition, in this embodiment, as Figure 3C As shown, the structure of the housing 1 is basically the same as that of the housing 1 in the first embodiment and the second embodiment, so the use of the plastic liner 2' will not cause a significant change in the structure of the housing 1, and the plastic liner 2' can also improve the dustproof and waterproof performance of the wearable electronic device.

[0110] Furthermore, if Figure 3B As shown, the plastic liner 2' is located inside the housing 1. The plastic liner 2' is fixed relative to the housing 1, and the housing 1 and the circuit board assembly 3 are separated by the plastic liner 2'. In this way, since the plastic liner 2' separates the housing 1 and the circuit board assembly 3 by a certain distance, a clearance for the antenna is formed, which can improve the performance of the antenna. Similar to the structure of the metal liner 2, as shown in FIG. Figure 3A As shown, the plastic liner 2' comprises an annular liner base 21' and liner extensions 22' formed integrally with the liner base 21', and two groups of liner extensions 22' extend from the liner base 21' toward both sides.

[0111] Furthermore, in order to ensure the electrical connection between the housing 1 and the circuit board assembly 3, the following solution is adopted in this embodiment. Figure 3BAs shown, the plastic liner 2' has a first portion 211' and a second portion 212'. The first portion 211' faces the inner circumferential surface 11i of the base of the housing 1, while the second portion 212' faces the circuit board assembly 3. The plastic liner 2' is provided with a conductive portion 23'. The conductive portion 23' extends from the first portion 211' along the outer surface of the plastic liner 2' to the second portion 212'. The conductive portion 23' in the first portion 211' is in constant contact with the conductive layer 13, and in the second portion 212' is in contact with the second elastic member 31 provided on the circuit board assembly 3. In this way, the housing 1 and the circuit board assembly 3 are well electrically connected via the conductive layer 13, the conductive portion 23', and the second elastic member 31, ensuring antenna performance. In this embodiment, the metal traces serving as the conductive portion 23' can be provided on the plastic liner 2' using laser direct structuring (LDS) or laser activated plating (LAP).

[0112] In addition, if Figure 3D As shown, the second elastic member 31 has a second body 311 and a second elastic piece 312. The second elastic piece 312 is formed by folding back from one end of the second body 311, and the second elastic piece 312 is bent multiple times to tilt relative to the second body 311. More specifically, as shown in FIG. Figure 3A As shown, the circuit board assembly 3 is provided with a second mounting recess 3c for accommodating and mounting a second elastic member 31. One end of the second elastic piece 312 is connected to the second body 311, and the other end of the second elastic piece 312 is tilted relative to the second body 311 to abut against the conductive portion 23' of the plastic liner 2'. In this way, the second elastic member 31 can improve the electrical conductivity between the conductive portion 23' of the plastic liner 2' and the circuit board assembly 3. In addition to using the second elastic member 31, in an optional solution, the electrical conductivity between the conductive portion 23' of the plastic liner 2' and the circuit board assembly 3 can also be improved by providing conductive glue or conductive cloth between the plastic liner 2' and the circuit board assembly 3.

[0113] In this embodiment, the outer shell 1 and the plastic liner 2' can be manufactured and assembled in a variety of ways. In a first optional method, the outer shell 1 and the plastic liner 2' are processed separately. A conductive layer 13 is provided on the inner surface of the outer shell 1. The plastic liner 2' is injection molded, and a conductive portion 23' is provided on the portion of the plastic liner 2' opposite the conductive layer 13. The outer shell 1 and the plastic liner 2' are then bonded together using an adhesive. In a second optional method, after the plastic liner 2' is processed by the injection molding process, it is placed in a mold and then laminated with multiple layers of carbon fiber, and then hot-pressed and cured to form an integrated composite structure. The plastic liner 2' can be made of polycarbonate (PC) and polyamide (PA) series plastics with higher softening points. These plastics have a natural softening point of 130°C-150°C. The addition of glass fiber can increase the softening point and strength. For example, after PA66 is reinforced with glass fiber, its heat deformation temperature can reach above 250°C. This ensures that the plastic liner does not soften or deform during the later carbon fiber molding process. At the same time, in order to enhance the bonding strength between the plastic material and the carbon fiber material, the surface of the plastic liner 2' can be pre-coated with an activator. In addition, in order to ensure that the plastic liner 2' does not deform during the process of hot pressing the carbon fiber on the outer layer, the hot pressing mold can be designed with corresponding internal supports. The conductive part 23' of the plastic liner 2' is also a metal coating formed using the above technology. After being wrapped by the carbon fiber material, the metal coating and the carbon fiber material are seamlessly connected and conductive, achieving an ideal conduction effect. In a third optional method, some protruding parts (such as bone positions) are designed at the conductive part of the corresponding circuit board assembly 3 of the shell 1. After the carbon fiber material is first hot-pressed into the shell 1 in the mold, the surface coating of the inner side of the shell 1 including the protruding parts forms a part of the antenna. Then, it is placed in the injection mold and the plastic liner 2' is injection-molded. The plastic liner 2' plays a filling and reinforcing role on the shell 1. The protruding portion of the housing 1 and the circuit board assembly 3 are electrically connected through contact compression or by means of springs, conductive fabric, conductive soft adhesive, etc., which can also achieve a good antenna effect. Similar to the housing 1 and the plastic liner 2', which can be manufactured and assembled in a variety of ways, the housing 1 and the metal liner 2 can also be manufactured and assembled in a similar manner.

[0114] In addition, in an optional solution, the housing 1 includes a protruding portion (such as a bone position or a reinforcing rib), the protruding portion extends through the plastic liner 2' to the circuit board assembly 3, the conductive layer 13 extends over the protruding portion, and the circuit board assembly 3 and the housing 1 are electrically connected via the protruding portion.

[0115] The structure of a wearable electronic device according to a fourth embodiment of the present application is described below.

[0116] (Structure of a Wearable Electronic Device According to a Fourth Embodiment of the Present Application)

[0117] The structure of the wearable electronic device according to the fourth embodiment of the present application is basically the same as the structure of the wearable electronic device according to the third embodiment of the present application. The following mainly describes the differences between the two.

[0118] In this embodiment, the conductive portion 23' does not extend through the outer surface (or upper surface) of the plastic liner 2' during the process of extending from the first portion 211' to the second portion 212'. Figure 4 As shown, the plastic liner 2' is formed with a via hole 2'h that passes through the plastic liner 2' from the side where the housing 1 is located toward the side where the circuit board assembly 3 is located. The conductive portion 23' extends from the first portion 211' through the via hole 2'h to the second portion 212'. In this way, the same effect as the third embodiment can be achieved.

[0119] The structure of a wearable electronic device according to a fifth embodiment of the present application is described below.

[0120] (Structure of a Wearable Electronic Device According to a Fifth Embodiment of the Present Application)

[0121] The structure of the wearable electronic device according to the fifth embodiment of the present application is basically the same as the structure of the wearable electronic device according to the third embodiment of the present application. The following mainly describes the differences between the two.

[0122] In order to improve the antenna performance of the housing 1 mainly made of carbon fiber, in this embodiment, as shown in FIG. Figure 5A and Figure 5B As shown, the base 11 and the conductive layer 13 are disconnected in the circumferential direction of the base. The base 11 and the conductive layer 13 form a gap (slit) 11g at the disconnected position. The housing 1 also includes a plastic filling block 14, which is located in the gap 11g and is fixed to the base 11. In this way, by setting the structural design of the above-mentioned gap, the segmented parts of the housing 1 can be used as Bluetooth antennas with different bands, antennas for the Global Positioning System (GPS), WIFI (Wireless Fidelity) antennas, and fourth-generation mobile communication technology / fifth-generation mobile communication technology antennas (4G / 5G communication antennas), thereby increasing the antenna signal transmission and reception efficiency.

[0123] Specifically, to achieve the above structure, the following manufacturing method can be used: First, multiple layers of carbon fibers are laminated and molded to form a blank for the housing 1; then, corresponding notches 11g are machined, and plastic is filled into these notches 11g through a molding process, thereby forming an integrated blank; finally, the finished housing 1 is machined.

[0124] Alternatively, another manufacturing method can be employed. First, slots are cut at regular locations in a carbon fiber prepreg (i.e., carbon fiber cloth). Plastic is then filled into the slots during hot press molding, and the resulting carbon fiber-plastic integrally molded housing 1 is molded. Finally, mechanical processing is performed to obtain the finished housing 1. To further improve antenna performance, a conductive layer 13 is applied to the remainder of the inner circumference 11i of the base 11 of the housing 1, except for the inner surface of the filler block 14, where no conductive layer is applied.

[0125] Furthermore, in this embodiment, the plastic liner 2' can be injection molded, and then the outer shell 1 and the plastic liner 2' can be bonded together with an adhesive to produce a carbon fiber composite molded body in which the outer shell 1 and the plastic liner 2' are integrated. Similarly, the outer shell 1 including the filler block 14 can be used as an insert, and the plastic liner 2' can be injection molded to produce a carbon fiber composite molded body in which the outer shell 1 and the plastic liner 2' are integrated.

[0126] Furthermore, if Figure 5B As shown, in order to enhance the bonding strength of the shell 1 at the notch 11g, a groove corresponding to the notch 11g of the shell 1 can be opened on the plastic liner 2' and a reinforcing block 213' can be installed, and then assembled with the plastic by gluing or mechanical structure. In an optional scheme, the carbon fiber prepreg (that is, carbon fiber cloth) used to manufacture the shell 1 is formed into notches 11g at regular positions and laminated, and glass fiber and other wave-transparent and tough fiber materials are laid at the notch 11g position, and cross-linked with the carbon fiber prepreg to increase the interface strength. In this optional scheme, the fibers can be arranged in a bent manner to increase the degree of intersection to improve the strength. In this way, the plastic liner 2' can not only be used for structural reinforcement and sealing, but also provide antenna clearance.

[0127] By adopting the above technical solution, in this embodiment, not only can the same effect as the fourth embodiment be achieved, but the antenna performance of the housing 1 can also be improved.

[0128] The structure of a wearable electronic device according to a sixth embodiment of the present application is described below.

[0131] In an optional solution, the wearable electronic device further includes a conductive adhesive, which is located between the housing 1 and the circuit board assembly 3, and the housing 1 and the circuit board assembly 3 are electrically connected via the conductive adhesive.
