Description

Technical Field

[0001] This application relates to the field of antenna technology, and more particularly to a wearable device. Background Technology

[0002] Currently, most antennas in smartwatches are integrated inside the body. However, in the presence of low-frequency bands, the longer wavelength of low-frequency signals necessitates larger antennas. Placing these antennas inside the body is problematic due to the limited space. This restricts the size and shape of the antenna, limiting its design flexibility and preventing it from achieving the desired performance within the confined space. Insufficient signal strength can significantly reduce the antenna's efficiency, further impacting the smartwatch's normal operation in low-frequency bands and ultimately hindering the user experience. Utility Model Content

[0003] This application provides a wearable device that can solve at least some of the aforementioned technical problems.

[0004] This application provides a wearable device, including:

[0005] A wearable body, the wearable body including a metal frame;

[0006] A wristband, comprising a first end and a second end, the first end and the second end being respectively connected to the metal frame, wherein a first metal component is provided at least near the first end of the wristband;

[0007] A first antenna, comprising a first metal component and a first middle frame portion within the metal middle frame, wherein the first middle frame portion is close to the first end and connected to the first metal component, and wherein the first antenna is used to receive and transmit signals in a first frequency band, the first frequency band including a low-frequency band.

[0008] This application provides a wearable device. The wearable device includes a wearable body, a wristband, and a first antenna. The wearable body includes a metal frame, and the wristband includes a first end and a second end, which are respectively connected to the metal frame. A first metal component is disposed in the wristband at least near the first end. The first antenna includes the first metal component and a first frame portion within the metal frame. The first frame portion is near the first end and connected to the first metal component. The first antenna is used to receive and transmit signals in a first frequency band, which includes a low-frequency band. This application sets the relatively large first antenna, which supports low-frequency bands, as the first metal part of the wristband and the first middle frame portion of the metal middle frame. This increases the installation space for the first antenna, avoiding limitations on its size and shape. This allows for better design flexibility and avoids insufficient signal strength. The first antenna can achieve the desired effect within sufficient space. Compared to existing technologies that place the first antenna in a limited space, this significantly improves the working efficiency of the first antenna, enabling the wearable device to operate normally in low-frequency bands. This, in turn, allows the wearable device to meet user needs and enhance the user experience. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely one embodiment of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of the embodiments of this application, it should be understood that the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The term "connection" in this application, unless otherwise specified, primarily refers to a physical structural connection; however, if specified, it may also include direct or indirect connections. The terms "first" and "second" in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0023] Please see Figure 1 , Figure 1This is a schematic diagram of a wearable device 100 according to an embodiment of this application. The wearable device 100 includes a wearable body 1, a wristband 2, and a first antenna 3. The wearable body 1 includes a metal frame 11. The wristband 2 includes a first end 21 and a second end 22, which are respectively connected to the metal frame 11. A first metal component 31 is disposed in the wristband 2 at least near the first end 21. The first antenna 3 includes the first metal component 31 and a first frame portion 32 in the metal frame 11. The first frame portion 32 is near the first end 21 and connected to the first metal component 31. The first antenna 3 is used to receive and transmit signals in a first frequency band, which includes a low-frequency band.

[0024] Therefore, by setting the relatively large first antenna 3, which supports the low-frequency band, as the first metal part 31 of the wristband 2 and the first middle frame part 32 of the metal middle frame 11, the installation space of the first antenna 3 is increased, avoiding the limitation of the size and shape of the first antenna 3. This allows the first antenna 3 to have better design flexibility and avoids the problem of insufficient signal strength. The first antenna 3 can achieve the expected effect in a sufficient space. Compared with the existing technology that sets the first antenna 3 in a limited space, the working efficiency of the first antenna 3 can be significantly improved, and the wearable device 100 can work normally in the low-frequency band, thereby meeting the user's needs and improving the user experience.

[0025] In some embodiments, the wristband 2 is used for a user to wear the smartwatch on their wrist. For example, the wearable device 100 is a smartwatch, smart bracelet, or other device that can be worn on the wrist via the wristband 2.

[0026] In some embodiments, such as Figure 1 As shown, at least the first middle frame portion 32 of the metal frame 11 has a mounting groove 12 on its periphery. The wristband 2 includes a first protrusion 23, which protrudes from the first end 21 in a direction away from the wristband 2. The first protrusion 23 is made of conductive material and is electrically connected to the first metal part 31. The first protrusion 23 is connected to the mounting groove 12 so that the first middle frame portion 32 is connected to the first metal part 31 through the first protrusion 23.

[0027] Thus, the first protrusion 23 is inserted into the mounting groove 12, connecting the first protrusion 23 to the mounting groove 12. Since the first protrusion 23 is made of conductive material and is electrically connected to the first metal part 31, and the first middle frame portion 32 is part of the metal middle frame 11, a connection can be established between the first metal part 31 and the first middle frame portion 32. The first middle frame portion 32 is electrically connected to the first metal part 31 through the first protrusion 23. This connection can also enhance the stability of the connection between the first middle frame portion 32 and the first metal part 31, and enhance the operational stability of the first antenna 3. Furthermore, the cooperation between the first protrusion 23 and the mounting groove 12 can also connect the wristband 2 to the metal middle frame 11, thereby completing the assembly of the wearable device 100.

[0028] In some embodiments, the first protrusion 23 may be made of a conductive material with good conductivity, such as metal, so that the first protrusion 23 and the first metal part 31 can achieve a better electrical connection.

[0029] In some embodiments, a first connecting structure is provided on both opposite sides of the peripheral sidewall of the metal frame 11, and a second connecting structure is provided on both sides of the wristband 2 near the first end 21 and the second end 22. Each second connecting structure of the wristband 2 is connected to the first connecting structure at the corresponding position on the peripheral sidewall of the metal frame 11 to fix the wristband 2 to the metal frame 11.

[0030] Thus, the wristband 2 is connected to the metal frame 11 through the first connecting structure and the second connecting structure to fix the wristband 2 and the metal frame 11 together, thereby completing the assembly of the wearable device 100. It can also enhance the connection stability between the wristband 2 and the metal frame 11, and prevent the connection between the wristband 2 and the metal frame 11 from breaking when the user uses the wearable device 100 or makes large movements. Furthermore, the connection between the wristband 2 and the metal frame 11 through the first connecting structure and the second connecting structure can further improve the connection stability between the first frame portion 32 and the first metal part 31, thereby enhancing the operational stability of the first antenna 3.

[0031] In some embodiments, such as Figure 1As shown, the first connecting structure includes two spaced-apart second protrusions 13, and each second protrusion 13 has a mounting hole (not shown in the figure) on one side facing the other second protrusion 13. The distance between the two second protrusions 13 of the first connecting structure is greater than the width of the wristband 2. The second connecting structure includes two protruding posts (not shown in the figure) disposed near the corresponding ends of the wristband 2 and located on both sides of the width direction of the wristband 2. The two protruding posts are respectively accommodated in the mounting holes of the two second protrusions 13 to fix the wristband 2 to the metal frame 11.

[0032] Thus, the two protruding posts are respectively accommodated in the mounting holes of the two second protrusions 13, so that the wristband 2 is connected to the metal frame 11 through the two protruding posts and the two second protrusions 13, thereby fixing the wristband 2 and the metal frame 11 together. This enhances the connection stability between the wristband 2 and the metal frame 11, preventing the connection between the wristband 2 and the metal frame 11 from breaking when the user uses the wearable device 100 or makes large movements. Furthermore, the connection between the wristband 2 and the metal frame 11 through the two protruding posts and the two second protrusions 13 can further improve the connection stability between the first frame portion 32 and the first metal part 31, thereby enhancing the operational stability of the first antenna 3.

[0033] Please see Figure 2 , Figure 2 This is a schematic diagram of a wearable device 100 according to another embodiment of this application. In some embodiments, the wearable device 100 further includes a second antenna 4, which includes a second frame portion 41 of the metal frame 11. The second antenna 4 is used to receive and transmit signals in a second frequency band, which is different from the first frequency band.

[0034] Therefore, by configuring the second frame portion 41 of the metal frame 11 as a second antenna 4 that supports a second frequency band different from the operating frequency band of the first antenna 3, the frequency band in which the wearable device 100 can operate is broadened, enabling the wearable device 100 to support operation in multiple frequency bands, thereby enhancing the functionality of the wearable device 100 and enabling it to support more functions and services. This, in turn, allows the wearable device 100 to meet user needs and improve the user experience. Furthermore, since the first antenna 3 and the second antenna 4 support different first and second frequency bands respectively, interference between the signals of the first and second frequency bands can be reduced, improving the quality of signal transmission and reception of the first antenna 3 and the second antenna 4, and increasing the efficiency of signal transmission and reception of the first antenna 3 and the second antenna 4.

[0035] in, Figure 2 The thick black line on the metal frame 11 in the diagram represents the dividing line between the first frame portion 32 and the second frame portion 41.

[0036] In some embodiments, two partitions are installed on the metal frame 11 to divide the metal frame 11 into two independent first frame portion 32 and second frame portion 41 as required. That is, the partitions are disposed between the first frame portion 32 and the second frame portion 41. The partitions are made of non-conductive material, for example, the partitions can be made of materials such as plastic.

[0037] In some embodiments, the partition can be installed on Figure 2 The location of the thick black line on the metal frame 11.

[0038] In some embodiments, the first frequency band is a low-frequency band and the second frequency band is a high-frequency band, or the first frequency band is one of the sub-bands of the low-frequency band and the second frequency band is another sub-band of the low-frequency band.

[0039] Thus, the wearable device 100 can support operation in multiple frequency bands, enhancing the functionality of the wearable device 100 and enabling it to support more functions and services; furthermore, the first antenna 3 and the second antenna 4 support different first and second frequency bands respectively, which can reduce interference between signals of the first and second frequency bands and improve the signal quality transmitted and received by the first antenna 3 and the second antenna 4.

[0040] When the first frequency band is one of the sub-bands in the low frequency band and the second frequency band is another sub-band in the low frequency band, the second frequency band is a higher sub-band in the low frequency band than the first frequency band. As a result, the size of the second antenna 4 for transmitting and receiving signals in the second frequency band is shorter, and the metal frame 11 has enough space to set up the second antenna 4, thereby avoiding affecting the normal operation of the second antenna 4.

[0041] Please see Figure 3 and Figure 4 , Figure 3 The diagram shows the simulation parameters of existing technologies where the antenna supporting low-frequency bands is entirely housed within the metal frame 11. Figure 4 This is a simulation parameter diagram of an embodiment of this application, wherein, Figure 4Specifically, the simulation parameter diagram of the embodiment in which the first antenna 3 supporting the low frequency band is set as the first metal part 31 of the wristband 2 and the first middle frame part 32 of the metal middle frame 11, and the second middle frame part 41 of the metal middle frame 11 is set as the second antenna 4 supporting the second frequency band different from the first frequency band supported by the first antenna 3, and the first frequency band is the low frequency band and the second frequency band is the high frequency band.

[0042] Specifically, Figure 3 and Figure 4 The horizontal axis represents frequency, and the vertical axis represents the standing wave ratio (VSWR) of the antenna in the corresponding frequency band. Figure 3 and Figure 4 In the top left corner, the first column of numbers corresponds to the triangular symbol number marked on the waveform; the second column represents the frequency value corresponding to that number; and the third column represents the VSWR (Standing Wave Ratio) of the antenna operating at the frequency value in the second column. This can be seen from... Figure 3 and Figure 4 From this, we can see that Figure 4 The VSWR of antennas in the low-frequency band is mostly significantly smaller than that of other antennas. Figure 3 The standing wave ratio (SWR) of the corresponding low-frequency band antenna, and Figure 4 The standing wave ratio of the antenna in the low frequency band is mostly closer to 1. Therefore, it can be seen that setting part of the first antenna 3 that supports the low frequency band on the wristband 2 can improve the impedance matching of the first antenna 3, and thus improve the working efficiency of the first antenna 3.

[0043] Please see Figure 5 , Figure 5 This is a schematic diagram of a wearable device 100 according to another embodiment of this application. In some embodiments, a second metal piece 51 is disposed at least near the second end 22 in the wristband 2. The wearable device 100 also includes a third antenna 5, which includes the second metal piece 51 and a third frame portion 52 in the metal frame 11. The third frame portion 52 is near the second end 22 and connected to the second metal piece 51. The third antenna 5 is used to receive and transmit signals in a third frequency band, which is different from the first and second frequency bands.

[0044] Therefore, by setting the second metal part 51 and the third frame portion 52 in the metal frame 11 as a third antenna 5 with a different operating frequency band than the first antenna 3 and the second antenna 4, the frequency band that the wearable device 100 can operate on is widened, enabling the wearable device 100 to support operation on multiple frequency bands, enhancing the functionality of the wearable device 100, and enabling the wearable device 100 to support more functions and services, thereby meeting user needs and improving the user experience; furthermore, since the first antenna 3, the second antenna 4 and the third antenna 5 support different first, second, and third frequency bands respectively, interference between signals of the three different frequency bands can be reduced, improving the quality of the transmitted and received signals of the first antenna 3, the second antenna 4 and the third antenna 5, and improving the efficiency of the transmitted and received signals of the first antenna 3, the second antenna 4 and the third antenna 5.

[0045] in, Figure 5 The thick black lines on the metal frame 11 are shown as the dividing lines between the first frame portion 32, the second frame portion 41, and the third frame portion 52.

[0046] In some embodiments, three partitions are installed on the metal frame 11 to divide the metal frame 11 into three independent middle frame portions: a first middle frame portion 32, a second middle frame portion 41, and a third middle frame portion 52. That is, the partitions are disposed between the first middle frame portion 32, the second middle frame portion 41, and the third middle frame portion 52. The partitions are made of non-conductive material, for example, they can be made of materials such as plastic.

[0047] In some embodiments, the partition can be installed on Figure 5 The location of the thick black line on the metal frame 11.

[0048] In some embodiments, the first frequency band is one of the sub-bands of the low-frequency band, the second frequency band is another sub-band of the low-frequency band, and the third frequency band is a high-frequency band; or, the first frequency band is one of the sub-bands of the low-frequency band, the second frequency band is a high-frequency band, and the third frequency band is another sub-band of the low-frequency band.

[0049] Therefore, the wearable device 100 can support operation in multiple frequency bands, enhancing the functionality of the wearable device 100 and enabling it to support more functions and services; furthermore, it can reduce interference between signals from three different frequency bands, improve the quality of the transmitted and received signals of the first antenna 3, the second antenna 4, and the third antenna 5, and improve the efficiency of the transmitted and received signals of the first antenna 3, the second antenna 4, and the third antenna 5.

[0050] Wherein, when the first frequency band is one of the sub-bands in the low frequency band, the second frequency band is another sub-band in the low frequency band, and the third frequency band is a high frequency band, the second frequency band is a sub-band in the low frequency band that is higher than the first frequency band. As a result, the size of the second antenna 4 for transmitting and receiving the second frequency band is shorter, and the metal frame 11 has enough space to set up the second antenna 4, thereby avoiding affecting the normal operation of the second antenna 4.

[0051] In some embodiments, such as Figure 5 As shown, a mounting groove 12 is also provided on the periphery of the third frame portion 52 in the metal frame 11. The wristband 2 includes a third protrusion 24, which protrudes from the second end 22 in a direction away from the wristband 2. The third protrusion 24 is made of conductive material and is electrically connected to the second metal part 51. The third protrusion 24 is connected to the corresponding mounting groove 12 so that the third frame portion 52 is connected to the second metal part 51 through the third protrusion 24.

[0052] In some embodiments, the third protrusion 24 may be made of a conductive material with good electrical conductivity, such as metal, so that the third protrusion 24 and the second metal part 51 can achieve a better electrical connection.

[0053] In some embodiments, the portion of the wristband 2 near the first end 21 is made of metal, and the first metal part 31 is the metal portion of the wristband 2 near the first end 21.

[0054] Therefore, the first metal part 31 is the part of the wristband 2 near the first end 21, which can increase the setting space of the first antenna 3, avoid the problem of insufficient signal strength of the first antenna 3, and enable the first antenna 3 to achieve the expected effect in a sufficient space, and further enable the wearable device 100 to work normally in the low frequency band; and, by incorporating the first metal part 31, that is, the part of the first antenna 3, into the wristband 2 itself, the connection stability of the first metal part 31 and even the first antenna 3 can be improved.

[0055] In some embodiments, the portion of the wristband 2 near the second end 22 is made of metal, and the second metal part 51 is the metal portion of the wristband 2 near the second end 22.

[0056] In some embodiments, the wristband 2 includes a band body, the band body including a first end 21 and a second end 22, and the first metal member 31 is disposed on the band body near the first end 21.

[0057] Therefore, the first metal component 31 is disposed at a position near the first end 21 of the strap, which can increase the placement space of the first antenna 3, avoid the problem of insufficient signal strength of the first antenna 3, and enable the first antenna 3 to achieve the expected effect in a sufficient space, thereby enabling the wearable device 100 to work normally in the low frequency band; and the first metal component 31 disposed on the strap can isolate the first metal component 31 from the human body, avoiding the influence of the human body on the first antenna 3.

[0058] In some embodiments, the second metal member 51 is disposed at a position near the second end 22 of the belt.

[0059] In some embodiments, the antenna portion on the wristband 2 can be set at the corresponding position of the wristband 2 by laser engraving and embedding a metal conductor, wherein the range of laser engraving can be adjusted according to the actual needs of the antenna.

[0060] In some embodiments, the wearable device 100 further includes a bottom shell 6, which is connected to the metal frame 11 to form an accommodating space 7. The wearable device 100 also includes a signal source and a conductive connector. The signal source is disposed within the accommodating space 7. The metal frame 11 includes a power supply position 8. The signal source is electrically connected to the power supply position 8 through the conductive connector to power the metal frame 11.

[0061] Thus, the signal source is electrically connected to the power supply position 8 through the conductive connector to power the metal frame 11, thereby enabling the antenna in the wearable device 100 to transmit and receive signals in the corresponding frequency band, so that the wearable device 100 can work normally.

[0062] In some embodiments, the conductive connector is a screw or bolt.

[0063] In some embodiments, when the wearable device 100 is a smartwatch, the wearable device 100 further includes a watch face, which is disposed at the opening of the accommodating space 7, and the periphery of the watch face is connected to the metal frame 11.

[0064] In some embodiments, the number of feed positions 8 may be one or less than the number of antennas in the wearable device 100, and two or more antennas operating in different frequency bands may share a single feed position 8.

[0065] In some embodiments, the number of power supply positions 8 can be set based on the number of antennas in the wearable device 100. For example, the wearable device 100 includes a first antenna 3, a second antenna 4, and a third antenna 5. When the first mid-frame portion 32, the second mid-frame portion 41, and the third mid-frame portion 52 are separated by the partition, the number of power supply positions 8 is three. Each power supply position 8 is located at the mid-frame portion of the corresponding antenna so that the first antenna 3, the second antenna 4, and the third antenna 5 can normally transmit and receive signals in the corresponding frequency band, enabling the wearable device 100 to work normally.

[0066] In some embodiments, the wearable device 100 further includes a circuit board 9, the signal source is disposed on the circuit board 9, the circuit board 9 has a first connection hole, the metal frame 11 has a second connection hole, the signal source is electrically connected to the first connection hole, the power supply position 8 is located at the second connection hole, and the conductive connector passes through the first connection hole and the second connection hole, so that the circuit board 9 is fixedly connected to the metal frame 11 through the conductive connector, and the signal source is electrically connected to the power supply position 8.

[0067] Thus, the conductive connector passes through the first connection hole and the second connection hole, so that the circuit board 9 is fixedly connected to the metal frame 11 through the conductive connector, and the signal source is electrically connected to the feed position 8, so as to realize the function of the antenna in the wearable device 100 to transmit and receive signals in the corresponding frequency band, and enable the wearable device 100 to work normally.

[0068] The signal source can be illustrated as follows: Figures 1-3 The circuit board 9 is connected by trapezoidal and triangular components to form a radio frequency link. The radio frequency link transmits a signal of the corresponding frequency band and transmits the signal to the corresponding antenna through the feed position 8 to radiate to the outside world, thus completing the signal transmission process. Conversely, the antenna transmits the received signal of the corresponding frequency band to the corresponding radio frequency link through the feed position 8, thus completing the signal reception process.

[0069] In some embodiments, the circuit board 9 protrudes outward to form a first protrusion, and the inner sidewall of the metal frame 11 protrudes outward to form a second protrusion. The first protrusion is provided with a first connecting hole, and the second protrusion is provided with a second connecting hole. The conductive connector passes through the first connecting hole and the second connecting hole so that the circuit board 9 is fixedly connected to the metal frame 11 through the conductive connector.

[0070] Therefore, the first protruding part is provided with a first connecting hole, and the second protruding part is provided with a second connecting hole. The conductive connector passes through the first connecting hole and the second connecting hole, so that the circuit board 9 is fixedly connected to the metal frame 11 through the conductive connector, and the signal source is electrically connected to the power supply position 8.

[0071] In some embodiments, the wristband 2 includes a first wristband 27 and a second wristband 28. The first wristband 27 includes a first end 21 and a third end 25 opposite to the first end 21. The second wristband 28 includes a second end 22 and a fourth end 26 opposite to the second end 22. The third end 25 of the first wristband 27 and the fourth end 26 of the second wristband 28 are detachably connected.

[0072] Therefore, the detachable connection between the first wristband 27 and the second wristband 28 makes it easy for users to wear and remove the wearable device 100, improving the convenience of using the wearable device 100.

[0073] The first wristband 27 and the second wristband 28 are the aforementioned straps, and the first wristband 27 and the second wristband 28 can be detachably connected by means of buckles, adhesives, magnets, etc.

[0074] Specifically, when the first wristband 27 and the second wristband 28 are detachably connected by a buckle, the third end 25 of the first wristband 27 is provided with a first buckle, and the fourth end 26 of the second wristband 28 is provided with a second buckle. The first buckle connects to the second buckle, so that the third end 25 and the fourth end 26 are detachably connected. When the first wristband 27 and the second wristband 28 are detachably connected by adhesive, the third end 25 of the first wristband 27 is provided with a first adhesive component, and the fourth end 26 of the second wristband 28 is provided with a second adhesive component. The first adhesive component connects to the second adhesive component, so that the third end 25 and the fourth end 26 are detachably connected. When the first wristband 27 and the second wristband 28 are detachably connected by magnetic attraction, the third end 25 of the first wristband 27 is provided with a first magnetic component, and the fourth end 26 of the second wristband 28 is provided with a second magnetic component. The first magnetic component connects to the second magnetic component, so that the third end 25 and the fourth end 26 are detachably connected.

[0075] In some embodiments, when the first wristband 27 and the second wristband 28 are fixedly connected together to form a band without the third end 25 and the fourth end 26, the band is made of an elastic material, and the user can wear the wearable device 100 on the wrist through the elasticity of the band.

[0076] In some embodiments, the metal frame 11 is annular.

[0077] Therefore, the annular metal frame 11 is more aesthetically pleasing and can also improve the comfort of the user when wearing the wearable device 100, thereby improving the user's experience and satisfaction when wearing the wearable device 100.
