Description

Technical Field

[0001] The present application relates to the technical field of wearable devices, and in particular to an antenna device, a watch body, and a wearable device. Background Art

[0002] Smartwatches are small in size and have compact internal components, making antenna design challenging. From a design perspective, metal frames not only enhance structural stability but also offer a stylish appearance. For smartwatches with metal frames, antennas are typically designed around the metal frame. As user demands continue to grow, the demand for smartwatches to be smaller and have more diverse communication functions continues to increase. However, current smartwatch antenna designs can accommodate limited communication specifications and exhibit poor performance. Summary of the Invention

[0003] The embodiments of the present application provide an antenna device, a watch body, and a wearable device. The antenna device of the present application can take into account multiple communication specifications and has excellent antenna performance.

[0004] In a first aspect, embodiments of the present application provide an antenna device for use with a watch body. The antenna device includes an outer frame, which is configured to surround the edge of a mainboard of the watch body. In other words, the mainboard is located within the space enclosed by the outer frame, and the mainboard may be a circuit board.

[0005] The outer frame includes at least three slots, which separate the outer frame into a first antenna radiator, a first isolation segment, and a second antenna radiator. It is understood that slots are provided between the first antenna radiator and the first isolation segment, between the first isolation segment and the second antenna radiator, and between the second antenna radiator and the first antenna radiator. The first isolation segment is located between the first and second antenna radiators.

[0006] The first antenna radiator includes a first feed point and a first ground point spaced apart from each other, both electrically connected to the mainboard. The second antenna radiator includes a second feed point and a second ground point spaced apart from each other, both electrically connected to the mainboard. The first isolation segment includes a third ground point spaced apart from each other, both electrically connected to the mainboard. The first isolation segment is configured to improve isolation between the first and second antenna radiators.

[0007] In the embodiment of the present application, the outer frame is divided into at least three independent metal segments through at least three gaps. Each metal segment can be equipped with a different antenna as needed, which is conducive to improving the design freedom of the antenna and integrating multiple antennas to meet the requirements of multiple antennas and multiple frequency bands, realize the various communication specifications of wearable devices, and meet the increasing communication needs of users. By providing a first isolation segment between the first antenna radiator and the second antenna radiator, the first isolation segment increases the distance between the first antenna radiator and the second antenna radiator. Since the first isolation segment is electrically connected to the mainboard, the coupling between the first antenna radiator and the second antenna radiator is reduced, which is conducive to improving the isolation between the first antenna radiator and the second antenna radiator, and effectively improving the antenna performance of the first antenna radiator and the second antenna radiator.

[0008] In one possible implementation, the third grounding point is located at the end of the first isolation segment. In this embodiment of the application, by setting the third grounding point at the end of the first isolation segment, it is beneficial to improve the isolation between the first antenna radiator and the second antenna radiator.

[0009] In one possible embodiment, the first isolation segment includes a third feeding point, which is spaced apart from the third grounding point and electrically connected to the mainboard. It is understandable that when the first isolation segment is provided with a third feeding point, the first isolation segment can serve as an antenna radiator. By using the first isolation segment as an antenna radiator, the embodiment of the present application increases the design freedom of the antenna of the wearable device, facilitates the design of more communication specifications to meet the increasing needs of users, and can improve the isolation between the first antenna radiator and the second antenna radiator.

[0010] In one possible embodiment, the antenna frequency band corresponding to the first antenna radiator is smaller than the antenna frequency band corresponding to the first isolation segment, and / or the antenna frequency band corresponding to the second antenna radiator is smaller than the antenna frequency band corresponding to the first isolation segment. This is conducive to the reasonable layout of the antenna position according to the antenna frequency band to take into account more communication specifications.

[0011] In other embodiments, the antenna frequency band corresponding to the first antenna radiator may also be greater than the antenna frequency band corresponding to the first isolation segment, and / or the antenna frequency band corresponding to the second antenna radiator may also be greater than the antenna frequency band corresponding to the first isolation segment.

[0012] In one possible embodiment, the extension length of the first antenna radiator is greater than the extension length of the first isolation segment, and / or the extension length of the second antenna radiator is greater than the extension length of the first isolation segment. The extension length of the first antenna radiator can be understood as the extension length of the edge of the first antenna radiator toward the mainboard side, the extension length of the second antenna radiator can be understood as the extension length of the edge of the second antenna radiator toward the mainboard side, and the extension length of the first isolation segment can be understood as the extension length of the edge of the first isolation segment toward the mainboard side. The extension length of the first antenna radiator and the extension length of the second antenna radiator are relatively long, and the sizes of the first antenna radiator and the second antenna radiator can be fully utilized to flexibly design the number and position of the feeding points and the grounding points, so as to flexibly set the antenna type, and it is also conducive to the integration of multiple antennas, taking into account multiple communication specifications.

[0013] In other embodiments, the extension length of the first antenna radiator may also be smaller than the extension length of the first isolation segment, and / or the extension length of the second antenna radiator may also be smaller than the extension length of the first isolation segment.

[0014] In one possible implementation, the first isolation segment is a radiator of a UWB antenna. By setting the first isolation segment as the radiator of the UWB antenna, UWB communication can be achieved, thereby increasing the communication specifications of the wearable device.

[0015] In one possible embodiment, the first antenna radiator is a radiator of a satellite communication antenna, and the first feed point is located between the 9 o'clock and 12 o'clock positions on the watch body. For example, the first feed point can be located at the 10 o'clock position on the watch body. Satellite communication antennas have relatively high requirements for the antenna's directional pattern. By setting the first feed point between the 9 o'clock and 12 o'clock positions on the watch body, the embodiment of the present application can meet the left-hand circular polarization of the satellite communication antenna and the performance requirements of the satellite communication antenna.

[0016] In one possible embodiment, the first feeding point is closer to the first end of the first antenna radiator, and the distance between the first feeding point and the first end is greater than or equal to 2 mm and less than or equal to 15 mm. Exemplarily, the distance between the first feeding point and the first end is 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm or 14 mm. The distance between the first feeding point and the first end cannot be too close. If the distance between the first feeding point and the first end is too close, the antenna will not be easily excited, and the current at the end of the first antenna radiator will be small and the impedance will be large, which is not conducive to matching. The embodiment of the present application is conducive to making full use of the first antenna radiator by setting the distance between the first feeding point and the first end to be greater than or equal to 2 mm and less than or equal to 15 mm, so that the antenna is easy to be excited and has good performance.

[0017] In one possible embodiment, the second antenna radiator is a radiator of a GPS antenna, and the 6 o'clock position of the watch body is set between the two ends of the second antenna radiator. In other words, the 6 o'clock position of the wearable device is located between the two ends of the second antenna radiator, that is, the second antenna radiator passes through the 6 o'clock position of the wearable device. The GPS antenna needs to cover more user postures and more usage scenarios. When the second antenna radiator is the radiator of the GPS antenna, by setting the 6 o'clock position of the wearable device between the two ends of the second antenna radiator, the GPS antenna has a better radiation pattern toward 6 o'clock, which is conducive to the excellent performance of the GPS antenna.

[0018] In one possible embodiment, the second feeding point is located between the 6 o'clock position and the 9 o'clock position of the watch body. For example, the second feeding point is located at the 8 o'clock position of the wearable device. Since the GPS antenna does not need to transmit signals but only needs to receive signals, right-hand circular polarization is required to be better. By setting the second feeding point between the 6 o'clock position and the 9 o'clock position of the wearable device, the right-hand circular polarization of the GPS antenna can be improved, and it is easier to cover more user postures and meet more usage scenarios.

[0019] In one possible implementation, the first antenna radiator is a radiator of at least one of a satellite communication antenna and a cellular antenna. By configuring the first antenna radiator as at least one of a satellite communication antenna and a cellular antenna, embodiments of the present application enable flexible configuration of antenna types and integration of multiple antennas, taking into account various communication specifications.

[0020] In one possible implementation, the second antenna radiator is a radiator of at least one of a GPS antenna and a short-range communication antenna. By configuring the second antenna radiator as at least one of a GPS antenna and a short-range communication antenna, the present embodiment allows for flexible configuration of antenna types and integration of multiple antennas, taking into account various communication specifications.

[0021] In one possible embodiment, the gap separating the outer frame further forms a second isolation segment, located between the first and second antenna radiators. The second isolation segment is provided with a fourth grounding point electrically connected to the mainboard, thereby improving the isolation between the first and second antenna radiators. Providing the second isolation segment between the first and second antenna radiators increases the spacing between them, and because the second isolation segment is electrically connected to the mainboard, it reduces the coupling between the first and second antenna radiators, thereby improving the isolation between the first and second antenna radiators and effectively enhancing the antenna performance corresponding to the first and second antenna radiators.

[0022] In one possible embodiment, the second isolation segment is spaced apart from the first isolation segment. Exemplarily, the second isolation segment and the first isolation segment are disposed on opposite sides of the watch body. By spacing the second isolation segment apart from the first isolation segment, the present application enables the second isolation segment and the first isolation segment to be dispersed between the first and second antenna radiators, achieving symmetrical and even distribution of the multiple metal segments of the outer frame and improving the aesthetic appearance.

[0023] In one possible embodiment, the second isolation segment includes a fifth grounding point. The fifth grounding point and the fourth grounding point are located at opposite ends of the second isolation segment. The fifth grounding point is electrically connected to the mainboard, thereby facilitating improved isolation between the first and second antenna radiators. Furthermore, since the fourth and fifth grounding points are located at opposite ends of the second isolation segment, a greater distance between the fourth and fifth grounding points is provided, significantly reducing the coupling between the first and second antenna radiators.

[0024] In one possible embodiment, the first antenna radiator includes a first lug, which is used to connect to the first strap of the wearable device, and the second antenna radiator includes a second lug, which is used to connect to the second strap of the wearable device. It can be understood that the 12 o'clock position of the wearable device corresponds to the first lug, and the 6 o'clock position of the wearable device corresponds to the second lug. The usage scenario of wearable devices is mainly worn on the wrist, and the antenna performance is greatly affected by the arm. The positions of the first lug and the second lug (near the 6 o'clock and 12 o'clock positions of the wearable device) are close to the outer edge of the arm when worn. Part of the first lug and the second lug do not fit the arm, and the antenna performance is less affected by the arm. It is a more favorable position for antenna design. Near the 3 o'clock and 9 o'clock positions of the wearable device, it is always directly above the arm when worn, fits the arm, and is greatly affected by the arm. In an embodiment of the present application, the first antenna radiator may include a first ear, and the second antenna radiator may include a second ear. The first antenna radiator and the second antenna radiator are arranged near the 6 o'clock and 12 o'clock positions of the wearable device, thereby ensuring that the antennas corresponding to the first antenna radiator and the second antenna radiator have good performance.

[0025] In one possible embodiment, the outer frame is provided with a mounting hole for mounting a button of the watch body, and at least one of the multiple slits in the outer frame is connected to the mounting hole. It is understood that the slits in the outer frame can be positioned at the position of the buttons of the wearable device, with the crown of the button obstructing the slits, thereby reducing the impact of the slits on the appearance of the wearable device, improving the aesthetics of the wearable device, and taking into account both antenna performance and watch appearance.

[0026] In one possible embodiment, the antenna device includes an insulating member, which is located between the outer frame and the button, thereby facilitating insulation between the button and the outer frame and preventing the button from electrically connecting multiple independent metal segments of the outer frame and affecting antenna performance.

[0027] In one possible embodiment, at least one of the plurality of slits in the outer frame is provided with an ink layer, the ink layer being used to form the exterior surface of the body. Ink layers of different colors can be provided based on the desired appearance to beautify the outer frame and enhance the aesthetics of the wearable device.

[0028] In one possible embodiment, the antenna device includes a recessed portion, the recessed portion being located within at least one of the plurality of slots in the outer frame. Providing the recessed portion can increase the design diversity of the slots and improve the aesthetic appearance of the wearable device.

[0029] In a second aspect, the present application provides a watch body, comprising a main board and an antenna device as described in any one of the aforementioned embodiments, wherein the antenna device is electrically connected to the main board.

[0030] In a third aspect, the present application provides a wearable device comprising a first strap, a second strap, and a watch body as described in any of the foregoing embodiments, wherein the first strap is connected to a first lug of the watch body, and the second strap is connected to a second lug of the watch body.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, a conflicting connection or an integrated connection; for ordinary technicians in this field, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0047] like Figure 1 and Figure 2 As shown, Figure 1is a structural diagram of a wearable device 100, Figure 2 for Figure 1 An exploded view of a portion of the structure of the wearable device 100 is shown. Figure 2 Not shown Figure 1 The wearable device 100 shown includes a first strap 10 and a second strap 20 .

[0048] Wearable device 100 may be a smartwatch. Wearable device 100 not only indicates time but also typically provides one or more functions, including reminders, navigation, calibration, monitoring, and interaction. For example, wearable device 100 can make calls, send and receive text messages, monitor sleep and heart rate, provide sedentary reminders, track running steps, take remote photos, play music, record videos, and use a compass. The multifunctional design and stylish appearance of wearable device 100 meet user needs and have broad application prospects.

[0049] Wearable device 100 may include a first strap 10, a second strap 20, and a watch body 40. The first strap 10 is connected to a first lug 3215 of the watch body 40, and the second strap 20 is connected to a second lug 3225 of the watch body 40. For example, the first strap 10 can be rotatably connected to the first lug 3215, and the second strap 20 can be rotatably connected to the second lug 3225. The first strap 10 and the second strap 20 can be made of rubber, metal, leather, nylon, or silk ribbon.

[0050] After the wearable device 100 is placed on the wrist or other position, the first strap 10 and the second strap 20 can be buckled together to wear the wearable device 100. When the wearable device 100 is no longer needed, the first strap 10 and the second strap 20 can be untied to remove the wearable device 100 from the wearing position.

[0051] See Figure 2 The watch body 40 may include an antenna device 30 and a mainboard 50. The mainboard 50 may be a circuit board, which may carry key components such as a central processing unit, a memory, and a radio chip, and connect various components of the wearable device 100 to ensure the normal operation of the wearable device 100 and communication with other devices. The mainboard 50 is not limited to Figure 2 As shown in the special shape, the main board 50 can be square or circular or other shapes. The shape of the main board 50 can be designed according to the space inside the wearable device 100.

[0052] The antenna assembly 30 is electrically connected to the mainboard 50 and may include an outer frame 32. The outer frame 32 surrounds the edge of the mainboard 50. The outer frame 32 may be circular or square, for example. The outer frame 32 may be made of metal, such as an aluminum alloy or a titanium alloy. Aluminum alloy, as a lightweight, high-strength metal material, not only offers excellent wear and corrosion resistance but also effectively reduces the overall weight of the watch, improving wearing comfort. Titanium alloy is lightweight, strong, and corrosion-resistant, maintaining stable performance in a variety of environments.

[0053] The wearable device 100 may further include a back cover ( Figure 1 and Figure 2 ), display module 33 and battery 34. The display module 33 and the back cover are spaced apart on opposite sides of the outer frame 32. The display module 33 and the back cover can be surrounded by the outer frame 32 to form a storage space for accommodating the motherboard 50, battery 34, etc. of the wearable device 100.

[0054] See Figure 2 The display module 33 has a display function and can display pictures or images to meet the user's usage needs. The display module 33 may include a display layer 331 and a touch layer 332 covering the display layer. The touch layer 332 can be used for touch operations by the user. The touch layer 332 may be a transparent glass cover, plastic or other materials with good light transmittance. The touch layer 332 is located at the outermost layer of the wearable device 100 and is in direct contact with the outside world. It plays a role in protecting the internal display layer 331 and preventing the display layer 331 from being impacted and scratched by the outside world. At the same time, it maintains good transparency and optical properties to ensure that the user can clearly see the content on the display layer 331. The display layer 331 may be a liquid crystal display, an active matrix organic light emitting diode display, a micro light emitting diode, a micro organic light emitting diode display, a quantum dot light emitting diode display or an organic light emitting diode display, etc.

[0055] See Figure 2 The battery 34 is located in the accommodation space of the wearable device 100 and can be fixed to the inside of the wearable device 100 through the bracket 31. The battery 34 is used to power the components inside the wearable device 100. The battery 34 is generally large in size and occupies a large internal space of the wearable device 100. The battery 34 can be Figure 2 The square shape shown may also be a circle or an irregular shape, etc. The embodiment of the present application does not specifically limit the shape and position of the battery 34.

[0056] Wearable device 100 may include a bezel 35. Bezel 35 may serve a decorative purpose. It also effectively prevents dust, moisture, steam, and the like from entering the wearable device 100 and potentially affecting its performance. Bezel 35 may be made of ceramic, which has an extremely high hardness. This ensures that bezel 35 maintains its aesthetic appearance even in extreme environments and is resistant to scratches, ensuring its aesthetics and durability during daily use. In other embodiments, bezel 35 may be made of metal.

[0057] The wearable device 100 may include a first button 361, a second button 362, and a third button 363 spaced apart. The outer frame 32 may have a first mounting hole 3291, a second mounting hole 3292, and a third mounting hole 3293. The first button 361 is located in the first mounting hole 3291, the second button 362 is located in the second mounting hole 3292, and the third button 363 is located in the third mounting hole 3293. The buttons of the wearable device 100 may be a power button, an operation button, a function button, or other buttons.

[0058] The first button 361 can be located at the 10 o'clock position of the wearable device 100, the second button 362 can be located at the 2 o'clock position of the wearable device 100, and the third button 363 can be located at the 4 o'clock position of the wearable device 100. The first button 361, the second button 362, and the third button 363 can also be located at other positions, which is not limited in the embodiment of the present application.

[0059] In other embodiments, the wearable device 100 may also have one button, two buttons, or four buttons, etc. The embodiment of the present application does not limit the number of buttons.

Figure 4 for Figure 3 A schematic structural diagram of a portion of the wearable device 100 from another angle is shown. Figure 5 for Figure 1A partial structural diagram of the wearable device 100 is shown. The outer frame 32 of the antenna assembly 30 may include at least three slits, which divide the outer frame 32 into at least three sections. For example, four slits may separate the outer frame 32 into a first antenna radiator 321, a second antenna radiator 322, a first isolation segment 323, and a second isolation segment 324. A slit is provided between any two of the first antenna radiator 321, the second antenna radiator 322, the first isolation segment 323, and the second isolation segment 324. Figure 3 Taking the example of the outer frame 32 having four slots, a first slot 325 is provided between the first antenna radiator 321 and the second isolation segment 324, a second slot 326 is provided between the first antenna radiator 321 and the first isolation segment 323, a third slot 327 is provided between the second antenna radiator 322 and the first isolation segment 323, and a fourth slot 328 is provided between the second antenna radiator 322 and the second isolation segment 324.

The first slot 325, the second slot 326, the third slot 327, and the fourth slot 328 all serve to separate the outer frame 32, forming four independent metal segments.

[0062] The first antenna radiator 321 includes a first feed point 3211 and a first ground point 3212 spaced apart from each other. Both the first feed point 3211 and the first ground point 3212 are electrically connected to the mainboard 50. The first feed point 3211 and the first ground point 3212 protrude from the main body of the first antenna radiator 321 and are located on the side of the first antenna radiator 321 facing the mainboard 50.

[0063] In some embodiments, the first antenna radiator 321 may further include a sixth grounding point 3213 and a seventh grounding point 3214, both of which are electrically connected to the mainboard 50. The sixth grounding point 3213 and the seventh grounding point 3214 protrude from the main body of the first antenna radiator 321 and are located on the side of the first antenna radiator 321 facing the mainboard 50. In other embodiments, the first antenna radiator 321 may further include other grounding points. The present embodiment does not limit the number of grounding points of the first antenna radiator 321.

[0064] It can be understood that the first feeding point 3211, the first grounding point 3212, the sixth grounding point 3213 and the seventh grounding point 3214 can be connected by the spring 371 (see Figure 4 ) or screw 372 (see Figure 4 and Figure 5) and other electrically connected to the mainboard 50. Take the first feeding point 3211 and the first grounding point 3212 as an example, which are electrically connected to the mainboard 50 through the screw 372, and the sixth grounding point 3213 and the seventh grounding point 3214 as an example, which are electrically connected to the mainboard 50 through the spring 371. For example, one end of the spring 371 is connected to the sixth grounding point 3213, and the other end of the spring 371 is connected to the mainboard 50. The spring 371 can be connected to the mainboard 50 through the conductive wire ( Figure 4 The first feed point 3211 is electrically connected to the mainboard 50 (not shown). The screw 372 is used to connect the bracket 31 and the first feed point 3211 to fix the bracket 31 to the outer frame 32, thereby increasing the connection stability of the bracket 31 and the battery 34 in the wearable device 100. The screw 372 electrically connects the first feed point 3211 and the mainboard 50. The electrical connection between the feeding point and the grounding point and the mainboard 50 can be selectively connected by a spring 371, a screw 372 or other means as needed, and this embodiment of the application is not limited to this.

[0065] See Figure 3 The second antenna radiator 322 includes a second feed point 3221 and a second ground point 3222 spaced apart from each other. Both the second feed point 3221 and the second ground point 3222 are electrically connected to the mainboard 50. The second feed point 3221 and the second ground point 3222 protrude from the main body of the second antenna radiator 322 and are located on the side of the second antenna radiator 322 facing the mainboard 50.

[0066] In some embodiments, the second antenna radiator 322 may further include an eighth grounding point 3223 and a ninth grounding point 3224 spaced apart from each other, each of which is electrically connected to the mainboard 50. The eighth grounding point 3223 and the ninth grounding point 3224 protrude from the main body of the second antenna radiator 322 and are located on the side of the second antenna radiator 322 facing the mainboard 50. In other embodiments, the second antenna radiator 322 may further include other grounding points, and the present embodiment does not limit the number of grounding points of the second antenna radiator 322.

[0067] The second feeding point 3221 , the second grounding point 3222 , the eighth grounding point 3223 and the ninth grounding point 3224 may be electrically connected to the mainboard 50 via spring clips or screws.

[0068] See Figure 3 The first isolation segment 323 includes a third grounding point 3231, which is electrically connected to the mainboard 50. The first isolation segment 323 is used to improve the isolation between the first antenna radiator 321 and the second antenna radiator 322. The third grounding point 3231 protrudes from the main body of the first isolation segment 323 and is located on the side of the first isolation segment 323 facing the mainboard 50. The third grounding point 3231 can be electrically connected to the mainboard 50 via a spring clip or screw.

[0069] See Figure 3 Second isolation segment 324 includes a fourth grounding point 3241, which is electrically connected to mainboard 50 and is used to improve the isolation between first antenna radiator 321 and second antenna radiator 322. Fourth grounding point 3241 protrudes from the main body of second isolation segment 324 and is located on the side of second isolation segment 324 facing mainboard 50.

[0070] In some embodiments, the second isolation segment 324 further includes a fifth grounding point 3242 . The fifth grounding point 3242 protrudes from the main body of the second isolation segment 324 and is located on a side of the second isolation segment 324 facing the main board 50 .

[0071] The fourth grounding point 3241 and the fifth grounding point 3242 can be electrically connected to the mainboard 50 through spring clips or screws, etc. The embodiment of the present application does not limit the electrical connection method between the docking points and the mainboard 50.

[0072] The fourth grounding point 3241 and the fifth grounding point 3242 of the second isolation segment 324 can be located at either end of the second isolation segment 324, respectively. The fourth grounding point 3241 is located at the end of the second isolation segment 324 near the first slit 325, while the fifth grounding point 3242 is located at the end of the second isolation segment 324 near the fourth slit 328. In other words, the fourth grounding point 3241 is close to the first antenna radiator 321, while the fifth grounding point 3242 is close to the second antenna radiator 322. This helps improve the isolation between the first antenna radiator 321 and the second antenna radiator 322. Furthermore, since the fourth grounding point 3241 and the fifth grounding point 3242 are located at either end of the second isolation segment 324, the distance between them is large, significantly reducing the coupling between the first antenna radiator 321 and the second antenna radiator 322.

[0073] In some embodiments, the second isolation segment 324 is spaced apart from the first isolation segment 323. For example, the second isolation segment 324 and the first isolation segment 323 are positioned on opposite sides of the watch body. By spacing the second isolation segment apart from the first isolation segment, the second isolation segment and the first isolation segment are dispersed between the first and second antenna radiators, achieving symmetrical and even distribution of the multiple metal segments of the outer frame and improving the aesthetics of the design.

[0074] The embodiment of the present application divides the outer frame 32 into at least three independent metal segments, each of which can be equipped with a different antenna as needed. This improves antenna design freedom and allows for the integration of multiple antennas to meet multi-antenna and multi-band requirements, enabling the wearable device 100 to support various communication specifications and meet the user's growing communication needs. A first isolation segment 323 is provided between the first antenna radiator 321 and the second antenna radiator 322. This increases the spacing between the first and second antenna radiators 321, 322, and because the first isolation segment 323 is electrically connected to the mainboard 50, it reduces the coupling between the first and second antenna radiators 321, 322. This improves the isolation between the first and second antenna radiators 321, 322, and effectively enhances the antenna performance of the first and second antenna radiators 321, 322. By setting a second isolation section 324 between the first antenna radiator 321 and the second antenna radiator 322, the second isolation section 324 increases the distance between the first antenna radiator 321 and the second antenna radiator 322. Since the second isolation section 324 is electrically connected to the mainboard 50, the coupling degree between the first antenna radiator 321 and the second antenna radiator 322 is reduced, which is beneficial to improving the isolation between the first antenna radiator 321 and the second antenna radiator 322, and effectively improving the corresponding antenna performance of the first antenna radiator 321 and the second antenna radiator 322.

[0075] See Figure 1 and Figure 3 , at least one of the first gap 325, the second gap 326, the third gap 327 and the fourth gap 328 is connected to the mounting hole. Exemplarily, the first gap 325 is provided at the position of the first button 361, and the first gap 325 is connected to the first mounting hole 3291, the second gap 326 is provided at the position of the second button 362, and the second gap 326 is connected to the second mounting hole 3292, the third gap 327 is provided at the position of the third button 363, and the third gap 327 is connected to the third mounting hole 3293. It can be understood that the gap of the outer frame 32 can be provided at the position of the button of the wearable device 100, and the gap is blocked by the crown of the button to weaken the impact of the gap on the appearance of the wearable device 100, thereby improving the aesthetics of the wearable device 100 and taking into account the antenna performance and the appearance of the watch. In addition, the bezel 35 can also block the gap to weaken the impact of the gap on the appearance of the wearable device 100. It can be understood that, Figure 1 The size of the bezel 35 is only a schematic representation, and the size of the bezel 35 can be larger to better cover the gap.

[0076] Taking the example of a first slit 325 located at the location of the first button 361 and connected to the first mounting hole 3291, if the first mounting hole 3291 is relatively small, the first slit 325 can be located in the middle of the first mounting hole 3291, which facilitates the first button 361 from blocking the first slit 325 and avoids the situation where the first button 361 blocks the first slit 325 when the first slit 325 is located at the edge of the first mounting hole 3291. If the first mounting hole 3291 is relatively large, the first slit 325 can be located in the middle of the first mounting hole 3291 or in a non-middle position of the first mounting hole 3291, and this is not limited in this application.

[0077] See Figure 1 and Figure 2 When the bezel 35 is made of metal, the metal bezel 35 also needs to be provided with gaps at positions corresponding to the first gap 325, the second gap 326, the third gap 327, and the fourth gap 328 to separate the bezel 35 into four independent metal segments. The gaps on the bezel 35 are connected to the gaps on the outer frame 32 to prevent the bezel 35 from electrically connecting the independent metal segments of the outer frame 32 when the bezel 35 is made of metal and no gaps are provided. In some embodiments, a scale can be provided on the bezel 35, and the gaps on the bezel 35 can be provided at the scale positions, such as providing gaps at the scale positions at the 3 o'clock or 9 o'clock positions of the bezel 35. Providing gaps at the scale positions can reduce the impact of the gaps on the appearance of the wearable device 100.

[0078] See Figure 3 The first antenna radiator 321 may include a first lug 3215, and the second antenna radiator 322 may include a second lug 3225. The 12 o'clock position of the wearable device 100 corresponds to the first lug 3215 and the first strap 10, and the 6 o'clock position of the wearable device 100 corresponds to the second lug 3225 and the second strap 20.

[0079] Understandably, the wearable device 100 is primarily worn on the wrist, and antenna performance is significantly affected by the arm. The first and second lugs 3215, 3225 are located near the outer edge of the arm when worn. Parts of the first and second lugs 3215, 3225 do not conform to the arm, making antenna performance less affected by the arm and a more favorable position for antenna design. The wearable device 100 near the 3 and 9 o'clock positions is always directly above the arm when worn, conforming to the arm and significantly affected by the arm. In this embodiment of the present application, the first antenna radiator 321 can include the first lug 3215, and the second antenna radiator 322 can include the second lug 3225. Positioning the first and second antenna radiators 321, 322 near the 6 and 12 o'clock positions of the wearable device 100 ensures good antenna performance for the first and second antenna radiators 321, 322.

[0080] In other embodiments, the first antenna radiator 321 may not include the first tab 3215, and the second antenna radiator 322 may not include the second tab 3225. That is, the first antenna radiator 321 and the second antenna radiator 322 may be located elsewhere on the wearable device 100, and this is not limited in this embodiment of the present application. In this embodiment of the present application, the first antenna radiator 321 includes the first tab 3215, and the second antenna radiator 322 includes the second tab 3225.

[0081] See Figure 3 In some embodiments, the third grounding point 3231 is located at the end of the first isolation segment 323. For example, the third grounding point 3231 is located at one end of the first isolation segment 323 near the second gap 326. In this embodiment of the present application, by arranging the third grounding point 3231 at the end of the first isolation segment 323, the isolation between the first antenna radiator 321 and the second antenna radiator 322 is improved.

[0082] The third grounding point 3231 can be electrically connected to the mainboard 50 via an inductor, capacitor, or antenna switch to achieve grounding. Inductors and capacitors have a certain degree of frequency selectivity. A relatively large inductor acts as a path for low-frequency signals but disconnects them for high-frequency signals; a relatively small capacitor acts as a path for high-frequency signals but disconnects them for low-frequency signals. This embodiment of the application uses the third grounding point 3231 being grounded via an antenna switch as an example.

[0083] See Figure 3In some embodiments, the first isolation segment 323 further includes a third feeding point 3232, which is spaced apart from the third grounding point 3231 and electrically connected to the mainboard 50. It is understandable that when the first isolation segment 323 is provided with the third feeding point 3232, the first isolation segment 323 can be the radiator of the antenna. For example, the first isolation segment 323 can be the radiator of a UWB antenna. That is, an ultra-wideband antenna (UWB). By setting the first isolation segment 323 as the radiator of the UWB antenna, UWB communication can be achieved. The embodiment of the present application increases the antenna design freedom of the wearable device 100 by using the first isolation segment 323 as the antenna radiator, which is conducive to designing more communication specifications to meet the increasing usage needs of users, and can improve the isolation between the first antenna radiator 321 and the second antenna radiator 322, thereby achieving decoupling of the first antenna radiator 321 and the second antenna radiator 322.

[0084] In some embodiments, the third grounding point 3231 can be located at one end of the first isolation segment 323 close to the second gap 326, and the third feeding point 3232 can be located at one end of the first isolation segment 323 close to the third gap 327, which is conducive to fully utilizing the length of the first isolation segment 323.

[0085] In some embodiments, the antenna frequency band corresponding to the first antenna radiator 321 is smaller than the antenna frequency band corresponding to the first isolation segment 323, or the antenna frequency band corresponding to the second antenna radiator 322 is smaller than the antenna frequency band corresponding to the first isolation segment 323, or the antenna frequency band corresponding to the first antenna radiator 321 is smaller than the antenna frequency band corresponding to the first isolation segment 323 and the antenna frequency band corresponding to the second antenna radiator 322 is smaller than the antenna frequency band corresponding to the first isolation segment 323. This is conducive to the reasonable layout of the antenna position according to the antenna frequency band to take into account more communication specifications.

[0086] It is understandable that the antenna frequency band corresponding to the first antenna radiator 321 can be set at some preferred locations to be smaller than the antenna frequency band corresponding to the first isolation segment 323, and / or the antenna frequency band corresponding to the second antenna radiator 322 can be set to be smaller than the antenna frequency band corresponding to the first isolation segment 323, so as to fully utilize the advantageous position of the antenna design of the wearable device 100. For example, when the first antenna radiator 321 and the second antenna radiator 322 are set near the 6 o'clock and 12 o'clock positions of the wearable device 100, the antenna performance corresponding to the first antenna radiator 321 and the second antenna radiator 322 is less affected by the arm. Therefore, the antenna frequency band corresponding to the first antenna radiator 321 can be designed to be smaller than the antenna frequency band corresponding to the first isolation segment 323, and / or the antenna frequency band corresponding to the second antenna radiator 322 can be designed to be smaller than the antenna frequency band corresponding to the first isolation segment 323.

[0087] Exemplarily, the first antenna radiator 321 is a radiator of at least one of a satellite communication antenna and a cellular antenna. The satellite communication antenna may include a satellite call antenna and a Beidou satellite messaging antenna. It is understandable that the first antenna radiator 321 may be a radiator of any one, any two, or any three of the satellite call antenna, the Beidou satellite messaging antenna, and the cellular antenna. In the embodiment of the present application, by setting the first antenna radiator 321 to be a radiator of at least one of a satellite communication antenna and a cellular antenna, the antenna type can be flexibly set, and the integration of multiple antennas can be achieved, taking into account multiple communication specifications. The first antenna radiator 321 can also be a radiator of other antennas, such as a 5G antenna. The specific setting can be as needed, and the embodiment of the present application does not limit this.

[0088] Exemplarily, the second antenna radiator 322 is a radiator of at least one of a GPS antenna and a short-range communication antenna. It is understandable that the short-range communication antenna may include a Bluetooth antenna and a WiFi antenna. The second antenna radiator 322 may be a radiator of any one, any two, or three of the GPS antenna, the Bluetooth antenna, and the WiFi antenna. In the embodiment of the present application, by setting the second antenna radiator 322 to be a radiator of at least one of a GPS antenna and a short-range communication antenna, it is possible to flexibly set the antenna type, and also to achieve the integration of multiple antennas, taking into account multiple communication specifications. The second antenna radiator 322 may also be a radiator of other antennas, such as a 5G antenna, and may be specifically set as needed, which is not limited in the embodiment of the present application. The GPS antenna may include the L1 frequency band of GPS and the L5 frequency band of GPS.

[0089] In other embodiments, the antenna frequency band corresponding to the first antenna radiator 321 may also be greater than the antenna frequency band corresponding to the first isolation section 323 , and / or the antenna frequency band corresponding to the second antenna radiator 322 may also be greater than the antenna frequency band corresponding to the first isolation section 323 .

[0090] See Figure 3 In some embodiments, the extension length of the first antenna radiator 321 is greater than the extension length of the first isolation segment 323, or the extension length of the second antenna radiator 322 is greater than the extension length of the first isolation segment 323, or the extension length of the first antenna radiator 321 is greater than the extension length of the first isolation segment 323 and the extension length of the second antenna radiator 322 is greater than the extension length of the first isolation segment 323. The extension length of the first antenna radiator 321 can be understood as the extension length of the edge of the first antenna radiator 321 facing the motherboard 50, the extension length of the second antenna radiator 322 can be understood as the extension length of the edge of the second antenna radiator 322 facing the motherboard 50, and the extension length of the first isolation segment 323 can be understood as the extension length of the edge of the first isolation segment 323 facing the motherboard 50.

[0091] Understandably, the longer extension lengths of the first antenna radiator 321 and the second antenna radiator 322 allow for flexible design of the number and location of feed and ground points, leveraging the dimensions of the first and second antenna radiators 321, 322. This allows for flexible configuration of antenna types and facilitates the integration of multiple antennas while accommodating multiple communication specifications. Furthermore, when the first and second antenna radiators 321, 322 are positioned near the 6 o'clock and 12 o'clock positions on the wearable device 100, these are advantageous antenna design locations, allowing for longer extension lengths to fully utilize the advantageous antenna design locations on the wearable device 100.

[0092] In other embodiments, the extension length of the first antenna radiator 321 may also be smaller than the extension length of the first isolation segment 323 , and / or the extension length of the second antenna radiator 322 may also be smaller than the extension length of the first isolation segment 323 .

[0093] When the first antenna radiator 321 is a satellite communication antenna, the first feed point 3211 can be located between the 9 and 12 o'clock positions of the watch body 40. For example, the first feed point 3211 can be located at the 10 o'clock position of the watch body 40. Satellite communication antennas have relatively high requirements for the antenna's directivity pattern. By arranging the first feed point 3211 between the 9 and 12 o'clock positions of the watch body 40, the embodiments of the present application can achieve left-hand circular polarization for the satellite communication antenna, thus meeting the performance requirements of the satellite communication antenna.

[0094] See Figure 3 As can be understood, the first antenna radiator 321 includes a first end 3216 and a second end 3217, with the first end 3216 being closer to the first slot 325 and the second end 3217 being closer to the second slot 326. The first feed point 3211 is closer to the first end 3216 of the first antenna radiator 321. The distance between the first feed point 3211 and the first end 3216 is greater than or equal to 2 mm and less than or equal to 15 mm. For example, the distance between the first feed point 3211 and the first end 3216 is 3 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, or 14 mm. The distance between the first feed point 3211 and the first end 3216 should not be too close. If the distance between the first feed point 3211 and the first end 3216 is too close, the antenna will not be easily excited. Furthermore, the end of the first antenna radiator 321 will have low current and high impedance, which is not conducive to matching. In the embodiment of the present application, the distance between the first feeding point 3211 and the first end 3216 is set to be greater than or equal to 2 mm and less than or equal to 15 mm, which is conducive to fully utilizing the first antenna radiator 321, making the antenna easy to be excited, and having good performance.

[0095] The first grounding point 3212, the sixth grounding point 3213, and the seventh grounding point 3214 are located between the first feeding point 3211 and the second gap 326. The first grounding point 3212, the sixth grounding point 3213, and the seventh grounding point 3214 can be evenly distributed or unequally spaced as needed. The present embodiment of the application does not limit the distribution of the first grounding point 3212, the sixth grounding point 3213, and the seventh grounding point 3214. The number of grounding points of the first antenna radiator 321 is not limited to three, and can also be one, two, or four, etc., and can be designed based on the type of antenna corresponding to the first antenna radiator 321 and the internal circuitry. It can be understood that the greater the number of grounding points of the first antenna radiator 321, the greater the degree of freedom in antenna debugging.

[0096] The first grounding point 3212, the sixth grounding point 3213, and the seventh grounding point 3214 can be electrically connected to the mainboard 50 via an inductor, capacitor, or antenna switch to achieve grounding. For example, the first grounding point 3212 can be grounded via an antenna switch, while the sixth grounding point 3213 and the seventh grounding point 3214 can be grounded via an inductor or capacitor. The grounding method for the different grounding points of the first antenna radiator 321 can be customized as needed. The grounding point of the first antenna radiator 321 can also be electrically connected to the mainboard 50 without an inductor, capacitor, or antenna switch, and this is not limited in this embodiment of the present application.

[0097] See Figure 3 When the second antenna radiator 322 is the radiator of the GPS antenna, the two ends of the second antenna radiator 322 are used to set the 6 o'clock position of the wearable device 100. In other words, the 6 o'clock position of the wearable device 100 is located between the two ends of the second antenna radiator 322, that is, the second antenna radiator 322 passes through the 6 o'clock position of the wearable device 100. The GPS antenna needs to cover more user postures and more usage scenarios. When the second antenna radiator 322 is the radiator of the GPS antenna, by setting the 6 o'clock position of the wearable device 100 between the two ends of the second antenna radiator 322, the GPS antenna has a better radiation pattern toward 6 o'clock, which is conducive to the excellent performance of the GPS antenna.

[0098] In some embodiments, the second feed point 3221 is located between the 6 o'clock position and the 9 o'clock position of the wearable device 100. For example, the second feed point 3221 is located at the 8 o'clock position of the wearable device 100. Since the GPS antenna does not need to transmit signals but only needs to receive signals, right-hand circular polarization is required. By setting the second feed point 3221 between the 6 o'clock position and the 9 o'clock position of the wearable device 100, the right-hand circular polarization of the GPS antenna can be improved, and it is easier to cover more user postures and meet more usage scenarios.

[0099] The second grounding point 3222, the eighth grounding point 3223, and the ninth grounding point 3224 are located between the second feed point 3221 and the third slot 327. The second grounding points 3222, the eighth grounding point 3223, and the ninth grounding point 3224 can be evenly distributed or unequally spaced as needed. The present embodiment does not limit the distribution of the second grounding points 3222, the eighth grounding point 3223, and the ninth grounding point 3224. The number of grounding points of the second antenna radiator 322 is not limited to three; it can also be one, two, or four, etc., and can be designed based on the type of antenna corresponding to the second antenna radiator 322 and its internal circuitry. It can be understood that a large number of grounding points on the second antenna radiator 322 provides greater flexibility in antenna debugging.

[0100] The second grounding point 3222, the eighth grounding point 3223, and the ninth grounding point 3224 can be electrically connected to the mainboard 50 via an inductor, capacitor, or antenna switch to achieve grounding. For example, the second grounding point 3222 and the eighth grounding point 3223 can be grounded via an antenna switch, while the ninth grounding point 3224 can be grounded via an inductor or capacitor. The grounding method for the different grounding points of the second antenna radiator 322 can be customized as needed. The grounding point of the second antenna radiator 322 can also be electrically connected to the mainboard 50 without an inductor, capacitor, or antenna switch, and this is not limited in this embodiment of the present application.

[0101] In some embodiments, the second antenna radiator 322 can be set with two feeding points, one feeding point can be located at the 8 o'clock position of the wearable device 100 and serve as the feeding point of the GPS antenna, and the other feeding point can be located at the 7 o'clock position of the wearable device 100 and serve as the feeding point of the Bluetooth antenna and the WiFi antenna.

[0102] In some embodiments, the fourth grounding point 3241 and the fifth grounding point 3242 of the second isolation segment 324 can be electrically connected to the mainboard 50 via an inductor, a capacitor, or an antenna switch to achieve grounding. For example, the fifth grounding point 3242 can be grounded via an antenna switch, and the fourth grounding point 3241 can be grounded via an inductor or a capacitor.

[0103] In some embodiments, the second isolation segment 324 may be provided with a fourth feed point ( Figure 3(not shown), the fourth feeding point and the fourth grounding point 3241 are spaced apart and electrically connected to the mainboard 50. It can be understood that when the second isolation segment 324 is provided with a fourth feeding point, the second isolation segment 324 can be a radiator of the antenna. The embodiment of the present application improves the antenna design freedom of the wearable device 100 by using the second isolation segment 324 as an antenna radiator, which is conducive to designing more communication specifications to meet the increasing usage needs of users, and can improve the isolation between the first antenna radiator 321 and the second antenna radiator 322, thereby achieving decoupling of the first antenna radiator 321 and the second antenna radiator 322.

[0104] It is understood that the first isolation segment 323 may be provided with a feeding point and a grounding point. The first isolation segment 323 serves as the radiator of the antenna. Alternatively, the first isolation segment 323 may be provided with a grounding point instead of a feeding point. The second isolation segment 324 may be provided with a feeding point and a grounding point. The second isolation segment 324 serves as the radiator of the antenna. Alternatively, the second isolation segment 324 may be provided with a grounding point instead of a feeding point.

[0105] In the embodiment of the present application, the first antenna radiator 321 can meet the high antenna gain and beamwidth requirements of satellite communication antennas and Beidou satellite messaging antennas, as well as the antenna bandwidth and efficiency requirements of cellular antennas. The second antenna radiator 322 can meet the antenna efficiency and pattern coverage requirements of GPS antennas in the L1 and L5 frequency bands. The first isolation segment 323 can meet the bandwidth and efficiency requirements of UWB antennas. Furthermore, good antenna isolation can be achieved between the various antennas.

[0106] like Figure 3 、 Figure 6 and Figure 7 As shown, Figure 6 for Figure 1 A partial structural diagram of the wearable device 100 is shown. Figure 7 for Figure 6 An enlarged view of the structure at X1 of a portion of the wearable device 100 is shown. The antenna assembly 30 may include an insulating member 38. The insulating member 38 includes a main portion 381, a first filling portion, a second filling portion 382, ​​a third filling portion, a fourth filling portion, a fifth filling portion 383, and a sixth filling portion. The first, second, third, fourth, fifth, and sixth filling portions are all positioned protruding from the main portion 381. The first filling portion is located within the first gap, the second filling portion 382 is located within the second gap 326, the third filling portion is located within the third gap, the fourth filling portion is located within the first mounting hole, the fifth filling portion 383 is located within the second mounting hole 3292, and the sixth filling portion is located within the third mounting hole. Figure 7For example, the second filling portion 382 is located within the second slit 326, and the fifth filling portion 383 is located within the second mounting hole 3292. The second filling portion 382 is located within the second slit 326, providing an insulated connection between the first antenna radiator 321 and the first isolation segment 323. The fifth filling portion 383 is located within the second mounting hole 3292 and between the outer frame 32 and the second button 362, providing an insulated connection between the second button 362 and the outer frame 32, thereby preventing electrical connection between the first antenna radiator 321 and the first isolation segment 323 through the second button 362.

[0107] It is understandable that the insulating member 38 can be made of plastic and can be connected to the outer frame 32 using a nano-injection molding process. The process is simple and the connection strength is high. The insulating member 38 connects multiple metal segments of the outer frame 32 into one.

[0108] like Figure 3 、 Figure 8 and Figure 9 As shown, Figure 8 for Figure 3 A schematic diagram showing a partial structure of the wearable device 100 from another angle is shown. Figure 9 for Figure 8 An enlarged view of the structure at X2 of a portion of the wearable device 100 is shown. The fourth slit 328 may include a first micro-slit 3281 and a second micro-slit 3282, which are spaced apart and serve to separate the second isolation segment 324 from the second antenna radiator 322. By dividing the larger fourth slit 328 into the smaller first micro-slit 3281 and second micro-slit 3282, the impact of the slit on the appearance of the wearable device 100 is reduced. It is understood that slits that are not located on buttons and have a significant impact on the appearance of the wearable device 100 can be configured as at least two micro-slits to reduce the impact of the slit on the appearance of the wearable device 100.

[0109] In some embodiments, the width of the first microslit 3281 may be greater than or equal to 0.15 mm and less than or equal to 0.6 mm. For example, the width of the first microslit 3281 may be 0.2 mm, 0.25 mm, 0.3 mm, 0.4 mm, or 0.5 mm. If the width of the first microslit 3281 is greater than 0.6 mm, the width of the first microslit 3281 is too large, which will affect the appearance of the wearable device 100. If the width of the first microslit 3281 is less than 0.15 mm, there will be a large tolerance caused by the process. By setting the width of the first microslit 3281 to be greater than or equal to 0.15 mm and less than or equal to 0.6 mm, the impact of the gap on the appearance of the wearable device 100 is reduced and it is beneficial to improve the accuracy of the process.

[0110] It is understandable that the width of the second microslit 3282 can be greater than or equal to 0.15 mm and less than or equal to 0.6 mm. For example, the width of the second microslit 3282 can be 0.2 mm, 0.25 mm, 0.3 mm, 0.4 mm, or 0.5 mm. The width of the first microslit 3281 can be the same as the width of the second microslit 3282 to improve the aesthetic appearance of the wearable device 100.
