[0035] The wearable device 100 provided by the embodiment of the present invention is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

[0036] like Figure 1 and Figure 2 As shown, the wearable device 100 according to an embodiment of the present invention includes a device body 10 , a first functional module 20 , and a coil 30 .

[0037] Specifically, the first functional module 20 is provided in the device body 10. The coil 30 is provided in the device body 10 and is wound in the horizontal direction or thickness direction of the device body. The coil 30 includes a first coil 31 and a second coil 32. The coil 30 is switchable between a first state and a second state. When the coil 30 is in the first state, the first coil 31, the second coil 32 and the first functional module 20 form a current path to realize the function corresponding to the first functional module 20; when the coil 30 is in the second state, the first coil 31 and the second coil 32 are disconnected, and the first coil 31 and the second coil 32 constitute the main antenna; wherein, when the coil 30 is in the first state, the function corresponding to the first functional module 20 is different from the function of the main antenna.

[0038] In other words, see Figure 1 and Figure 2According to an embodiment of the present invention, the wearable device 100 mainly comprises a device body 10, a first functional module 20, and a coil 30. The first functional module 20 is disposed within the device body 10. The coil 30 is disposed within the device body 10 and can be wound horizontally or in the thickness direction of the device body 10 to facilitate forming different types of capacitors. The coil 30 mainly comprises a first coil 31 and a second coil 32. The coil 30 is switchable between a first state and a second state. When the coil 30 is in the first state, a current path is formed between the first coil 31, the second coil 32, and the first functional module 20, thereby implementing the function corresponding to the first functional module 20. When the coil 30 is in the first state, the function corresponding to the first functional module 20 is different from that of the main antenna. When the coil 30 is in the second state, the first coil 31 and the second coil 32 are disconnected, and the first coil 31 and the second coil 32 can form the main antenna, enabling normal communication of the wearable device 100. By integrating the main antenna with the first functional module 20 and reusing the main antenna to realize different functions of different wearable devices 100, the space utilization of the wearable device 100 is greatly improved, and the miniaturization and diversification of the device can be taken into account at the same time, reducing costs and improving user experience.

[0039] In the present invention, the wearable device 100 may be a smart wearable product such as smart glasses, smart watches, smart bracelets, etc. In the following embodiments of the present invention, smart glasses may be used as the wearable device 100 for specific description, wherein, for example Figure 1 As shown, the smart glasses include a frame and temples 11, wherein Figure 2 The frame serves as the device body 10, and the first functional module 20 and the coil 30 are arranged in the frame (device body 10). The first functional module 20 can be a wireless charging module. Taking the first functional module 20 as a wireless charging module as an example, the first functional module 20 has a wireless charging circuit. When the coil 30 is in the first state, the coil 30 is connected to the wireless charging circuit, which can realize wireless charging of the wearable device 100.

[0040] In traditional wearable devices 100, taking smart glasses as an example, the glasses body (device body 10) is usually separated from the battery of the smart glasses. Because the battery is heavy, by separating the battery from the smart glasses, the weight of the smart glasses can be reduced, and the weight of the smart glasses can be reduced. However, when the battery is separated from the smart glasses, when the smart glasses are exhausted, it is necessary to carry an additional battery to charge the smart glasses, which is inconvenient to use. Of course, existing smart glasses can also be equipped with a small battery in the glasses body to meet power requirements, but the small battery has low capacity and short battery life, which will also reduce the user experience.

[0041] However, the present application switches the first state and the second state of the coil 30. When the wearable device 100 is not in use or when the battery is exhausted, the coil 30 can be directly switched to the first state to realize the function of the first functional module 20 (for example, a wireless charging module) and quickly charge the wearable device 100. When the wearable device 100 is in normal use, the coil 30 can be switched to the second state, and the coil 30 forms the main antenna to realize normal communication of the wearable device 100. By integrating the main antenna with the first functional module 20 and reusing the main antenna to realize different functions of different wearable devices 100, the space utilization rate of the wearable device 100 is greatly improved, and the miniaturization and diversification of the device can be taken into account at the same time, reducing costs and improving user experience.

[0042] It should be noted that the switching of the coil 30 between the first state and the second state can be achieved by folding or unfolding the temples 11 of the smart glasses. When the temples 11 of the smart glasses are folded, the coil 30 can be in the first state. When the temples 11 are unfolded, the coil 30 can be in the second state. Of course, the switching of the coil 30 between the first state and the second state can be achieved through touch or other signal detection methods, which will not be described in detail in the present invention.

[0043] Thus, according to an embodiment of the present invention, a wearable device 100 is provided with a coil 30 within the device body 10. In a first state, the coil 30 can form a current path with the first functional module 20, thereby implementing the corresponding functions of the first functional module 20. In a second state, the coil 30 can constitute a main antenna, enabling normal communication of the wearable device 100. By integrating the main antenna with the first functional module 20 and reusing the main antenna to implement different functions of different wearable devices 100, the space utilization of the wearable device 100 is greatly improved, while simultaneously taking into account the miniaturization and diversification of the device, reducing costs, and improving the user experience.

[0044] According to one embodiment of the present invention, the coil 30 is loaded with a lumped capacitor 41 at the first position, the second position, and the third position, respectively. The coil 30 forms a main antenna grounding point 33 at the first position, the coil 30 forms a main antenna feeding point 34 at the second position, and the coil 30 forms a main antenna tuning switch 35 at the third position.

[0045] That is to say, if Figure 2 As shown, the coil 30 can be loaded with lumped capacitors 41 at different positions. For example, the lumped capacitors 41 are loaded at the first position, the second position, and the third position of the coil 30 (see FIG. Figure 2In the first position, coil 30 forms a main antenna grounding point 33; in the second position, coil 30 forms a main antenna feeding point 34; and in the third position, coil 30 forms a main antenna tuning switch 35, thereby enabling the main antenna to provide signals of different frequency bands. Furthermore, the main antenna coordination switch can be used to adjust the main antenna to correspond to the different frequency bands required by wearable device 100, thereby meeting the different frequency band usage requirements of wearable device 100 and achieving the purpose of reusing the main antenna. This further reduces the installation space required for wearable device 100, meets the requirements for miniaturization and lightweighting of wearable device 100, and enhances the user experience.

[0046] Alternatively, as Figure 5 As shown, metal plates 42 can be placed at the first, second, and third positions of the coil 30. The first position of the coil 30 forms a main antenna grounding point 33, the second position forms a main antenna feed point 34, and the third position forms a main antenna tuning switch 35. The coupling between the metal plates 42 forms distributed capacitance, which is equivalent to loading a lumped capacitor 41 on the coil 30.

[0047] According to one embodiment of the present invention, the length of the first coil 31 is greater than that of the second coil 32. When the coil 30 is in the second state, a double-branch switch tuning antenna is formed between the first position, the second position and the third position.

[0048] In other words, if Figure 3As shown, when the first coil 31 and the second coil 32 are unfolded, the length of the first coil 31 is greater than the length of the second coil 32. When the coil 30 is in the second state, the first coil 31 and the second coil 32 are disconnected, and a double-branch switch tuning antenna is formed between the first position, the second position and the third position. The double-branch switch tuning antenna can be an inverted-F antenna (IFA). At this time, the first coil 31 is longer than the second coil 32, and the resonance points of the two branches are close, which can expand the working bandwidth of the main antenna. At this time, the working frequency band of the main antenna can be adjusted to the required frequency band by the different positions of the first position, the second position and the third position on the coil 30, which can be Global System for Mobile Communication (GSM), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), New Radio (NR), wireless network (WIFI), Bluetooth, etc. Of course, the first position, the second position and the third position on the coil 30 can be specifically set according to actual needs, and will not be described in detail in the present invention.

[0049] According to one embodiment of the present invention, a first switch 71 is provided between the first coil 31 and the second coil 32. When the first switch 71 is closed, the coil 30 is in the first state. When the first switch 71 is open, the coil 30 is in the second state.

[0050] That is to say, if Figure 2 and Figure 5 As shown, a first switch 71 can be provided between the first coil 31 and the second coil 32. The first switch 71 can be a single-pole single-throw switch, which controls the on / off state between the first coil 31 and the second coil 32. When the first switch 71 is closed, the coil 30 is in the first state, forming a current path between the coil 30 and the first functional module 20. When the first switch 71 is open, the coil 30 is in the second state, the first coil 31 and the second coil 32 are disconnected, and the coil 30 forms the main antenna.

[0051] According to one embodiment of the present invention, the wearable device 100 also includes: a second functional module 50, a second switch 72 is provided between the first circle 31 and the second circle 32, and when the second switch 72 is closed, the first circle 31, the second circle 32 and the first functional module 20 form a current path; or, the first circle 31, the second circle 32 and the second functional module 50 form a current path.

[0052] In other words, if Figure 4 and Figure 6 As shown, the wearable device 100 may further include a second functional module 50. The functions of the second functional module 50 and the first functional module 20 may be different, thereby facilitating the realization of different functions. A second switch 72 may be provided between the first coil 31 and the second coil 32. The second switch 72 may be a double-pole double-throw switch. The double-pole double-throw switch can be used to switch between the first functional module 20 and the second functional module 50, thereby realizing the switching of different functions. When the second switch 72 is closed, at this time, if the second switch 72 is switched to connect to the first functional module 20, the first coil 31, the second coil 32 and the first functional module 20 form a current path, thereby realizing the corresponding function of the first functional module 20. Alternatively, when the second switch 72 is switched to connect to the second functional module 50, the first coil 31, the second coil 32 and the second functional module 50 form a current path, thereby realizing the function of the second functional module 50.

[0053] In some specific embodiments of the present invention, the wearable device 100 further includes: a third functional module 60, a third switch 73 is provided between the first coil 31 and the second coil 32, and when the third switch 73 is closed, the coil 30 forms a current path with the first functional module 20, the second functional module 50, or the third functional module 60. When the first functional module 20, the second functional module 50, or the third functional module 60 is in operation, the operating frequency of the coil 30 is different.

[0054] That is to say, if Figure 7 As shown, the wearable device 100 may further include a third functional module 60. A third switch 73 may be provided between the first and second coils 31 and 32. The third switch 73 may be a double-pole, triple-throw (DPTT) switch. The DPTT switch can be used to switch between the first functional module 20, the second functional module 50, and the third functional module, thereby switching between different functions. When the third switch 73 is closed and connected to the first functional module 20, the first and second coils 31, 32, and the first functional module 20 form a current path, implementing the corresponding function of the first functional module 20. Alternatively, when the third switch 73 is connected to the second functional module 50, the first and second coils 31, 32, and the second functional module 50 form a current path, implementing the function of the second functional module 50. Alternatively, when the third switch 73 is connected to the third functional module 60, the first and second coils 31, 32, and the third functional module 60 form a current path, implementing the function of the third functional module 60. Furthermore, when the first functional module 20 , the second functional module 50 or the third functional module 60 is working, the operating frequency of the coil 30 is different, so as to facilitate the realization of different functions of the wearable device 100 .

[0055] According to one embodiment of the present invention, the first functional module 20 is a wireless charging module, the second functional module 50 is an NFC module, and the third functional module 60 is a cellular antenna module.

[0056] That is, see Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The first functional module 20 may be a wireless charging module, which includes a wireless charging circuit. Figure 4 、 Figure 6 and Figure 7 As shown, the second functional module 50 may be a Near Field Communication (NFC) module, which includes an NFC circuit. Figure 7 As shown, the third functional module 60 may be a cellular antenna module, which has a cellular antenna feeding point.

[0057] like Figure 2 and Figure 5 As shown, when the first functional module 20 (wireless charging module) is provided in the device body 10, a single-pole single-throw switch is loaded at the intersection of the first coil 31 and the second coil 32 of the coil 30 to control the on-off state between the first coil 31 and the second coil 32. A lumped capacitor 41 is loaded between different positions of the coil 30, which is equivalent to an on state in the main antenna frequency band and an off state in the NFC frequency band. When the single-pole single-throw switch is in the on state, the first coil 31 and the second coil 32 are connected to form a closed coil 30. At this time, the wireless charging circuit in the wireless charging module works to realize the wireless charging function. When the single-pole single-throw switch is in the off state, the first coil 31 and the second coil 32 are disconnected to form the main antenna. The first position, the second position and the third position on the coil 30 form a dual-branch switch-tuned IFA antenna. At this time, the first coil 31 is longer than the second coil 32, and the resonance points of the two branches are close, which can expand the working bandwidth of the main antenna. The operating frequency band of the main antenna can be adjusted to a desired frequency band by adjusting the first, second, and third positions of the coil 30, such as GSM, WCDMA, LTE, NR, WIFI, Bluetooth, etc. The operating principles of antennas, cellular antennas, etc. are understandable and achievable to those skilled in the art and will not be described in detail in this disclosure.

[0058] like Figure 4 and Figure 6As shown, when the device body 10 is provided with a first functional module 20 (wireless charging module) and a second functional module 50 (NFC module), the coil 30 can be switched to different circuits through a double-pole double-throw switch, thereby realizing the conversion between the NFC function and the wireless charging function. Taking smart glasses as an example, the wireless charging function can be awakened after the glasses are taken off (the temples 11 are folded) according to the user's actual usage scenario, and placed on a specific electrical appliance for fast charging. The NFC function is awakened when the glasses are worn (the temples 11 are not folded), which can be used for fast connection between smart glasses and other devices.

[0059] like Figure 7 As shown, when the device body 10 is equipped with a first functional module 20 (wireless charging module), a second functional module 50 (NFC module), and a third functional module 60 (cellular antenna), the coil 30 can be switched to different circuits via a double-pole triple-throw switch. When the double-pole triple-throw switch is switched to the NFC circuit, the NFC function is realized. When the double-pole triple-throw switch is switched to the wireless charging circuit, the wireless charging function is realized. When the double-pole triple-throw switch is switched to the cellular antenna feed, the cellular antenna function is realized.

[0060] Among them, such as Figure 8 and Figure 9 As shown, the two ports of the cellular antenna can be set to one port connected to the matching load 81 (adjusted to a non-reflective state) or grounded 82, and the other port connected to the feed 83. When one port is in the state of connecting to the matching load 81, the coil 30 is a traveling wave antenna (see Figure 8 When the coil 30 is in the grounded state 82, it is a standing wave antenna (see Figure 9 ).like Figure 10 As shown in the figure, the current direction of the traveling wave antenna is the direction of the arrow. When t=0, the "hollow circle" at point AC represents the current node, and the "solid circle" at point BD represents the current antinode. Figure 11 As shown in the figure, when t=T / 4, the current direction will also change. At this time, point AC becomes the current antinode point, and point BD becomes the current node point. The change in current direction will cause the polarization of the electromagnetic wave in the far field to change. Therefore, the traveling wave antenna can radiate circularly polarized waves and can be used as a GPS positioning antenna. Figure 12 As shown, the direction of the standing wave antenna current is in the direction of the arrow, the "hollow circle" at point AC represents the current antinode point, and the "solid circle" at point BD represents the current wave node. At this time, the current direction is from bottom to top, which is equivalent to a monopole antenna. By adding a matching and adjusting impedance at another port feed 83, GSM, WCDMA, LTE, NR, WIFI, Bluetooth antenna and other functions can be realized. The specific working frequency band can be matched and adjusted according to the length of the coil 30.

[0061] The design of the present invention can solve the problem of short battery life. A wireless charging function is added to the glasses, allowing users to charge wirelessly after taking off their glasses. At the same time, in order to solve the space and lightweight problems, the present invention integrates the wireless charging module, NFC module and main antenna into one. After taking off the glasses (folding the temples 11), the wireless charging function can be awakened and placed on a specific slave appliance for fast charging. When wearing glasses (without folding the temples 11), the NFC function can be awakened, which can be used for fast connection between smart glasses and other devices; when wearing glasses (without folding the temples 11), the main function is awakened at the same time to achieve normal communication of smart glasses. The present invention reuses three antennas, greatly improving space utilization while reducing costs.

[0062] In the present invention, the antenna structure is a coil 30, which can be implemented using processes such as LCP, FPC, and LDS. The switch can be a PIN switch or a MEMS switch. The number of turns of coil 30 can be one, two, three, or even more. The main antenna can be an IFA, a monopole antenna, a dipole antenna, or the like.

[0063] In some specific embodiments of the present invention, Figure 2 and Figure 4 As shown, the first circle 31 and the second circle 32 are spaced apart and distributed in the horizontal direction of the device body 10. Taking smart glasses as an example, the first circle 31 and the second circle 32 can be arranged along the plane of the frame. Figures 5 to 7 As shown, the first coil 31 and the second coil 32 can also be distributed in a spaced-apart manner in the thickness direction of the device body 10. For example, the first coil 31 and the second coil 32 can be distributed in a spaced-apart manner in the thickness direction of the frame, forming the coil 30 into a three-dimensional structure. By routing the wires in the thickness direction of the frame, the capacitance between the first coil 31 and the second coil 32 can be achieved through distributed capacitance. By routing the wires in the thickness direction of the device body 10, the coil 30 saves size in the planar direction, which is suitable for situations where the planar size layout is tight. On the other hand, the distributed capacitance can be used to achieve coupling, grounding, power feeding, and tuning of the first coil 31 and the second coil 32, saving costs.

[0064] In some specific embodiments of the present invention, there are two coils 30, and the two coils 30 are spaced apart and distributed in the device body 10, wherein one coil 30 corresponds to a first functional module 20, and the other coil 30 corresponds to a first functional module 20 and a second functional module 50.

[0065] That is, there are two coils 30. The two coils 30 are spaced apart and distributed in the device body 10, wherein one coil 30 corresponds to one first functional module 20, and the other coil 30 corresponds to one first functional module 20 and one second functional module 50. Taking smart glasses as an example, a coil 30 can be set on each of the left and right frames. The coil 30 is loaded on the left frame, such as Figure 2 and Figure 5 As shown, a single-pole single-throw switch is loaded at the intersection of the first coil 31 and the second coil 32 of the coil 30 to control the on-off state between the first turn and the second turn of the coil 30. The coil 30 is loaded on the right frame, as shown in FIG. Figure 4 and Figure 6 As shown, a double-pole double-throw switch switches between different circuits to switch between NFC and wireless charging functions. Depending on the user's actual usage scenario, the wireless charging function is activated after removing the glasses (folding the temples 11) and placed on a specific appliance for fast charging. The NFC function is activated while the glasses are worn (with the temples 11 unfolded) for quick connection between the smart glasses and other devices.

[0066] Of course, for those skilled in the art, other structures and working principles of the wearable device 100 are understandable and achievable, and will not be described in detail in the present invention.

[0067] In summary, according to the wearable device 100 of an embodiment of the present invention, a coil 30 is provided in the device body 10. In a first state, the coil 30 can form a current path with the first functional module 20, the second functional module 50, or the third functional module 60, thereby implementing the corresponding function of the first functional module 20.
