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

As shown in fig. 1 and 2, a 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.

Specifically, the first functional module 20 is provided inside the apparatus main body 10. The coil 30 is arranged in the device body 10, the coil 30 is wound in the horizontal direction or the thickness direction of the device body, the coil 30 comprises a first coil body 31 and a second coil body 32, the coil 30 is switchable between a first state and a second state, and when the coil 30 is in the first state, the first coil body 31, the second coil body 32 and the first functional module 20 form a current path to realize the corresponding function of the first functional module 20; when the coil 30 is in the second state, the first coil body 31 and the second coil body 32 are disconnected, and the first coil body 31 and the second coil body 32 form a main antenna; when the coil 30 is in the first state, the function of the first functional module 20 is different from that of the main antenna.

In other words, referring to fig. 1 and 2, the wearable device 100 according to the embodiment of the present invention is mainly composed of the device main body 10, the first functional module 20, and the coil 30. Wherein the first functional module 20 is provided within the apparatus body 10. The coil 30 is provided in the apparatus body 10, and the coil may be wound in a horizontal direction or a thickness direction of the apparatus body 10, so as to form a capacitance of different forms. The coil 30 mainly comprises a first coil body 31 and a second coil body 32, the coil 30 is switchable between a first state and a second state, and when the coil 30 is in the first state, a current path can be formed among the first coil body 31, the second coil body 32 and the first functional module 20, so as to realize the corresponding function of 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 ring body 31 and the second ring body 32 are disconnected, and the first ring body 31 and the second ring body 32 may form a main antenna, so that normal communication of the wearable device 100 is realized. Through being integrated as an organic whole with main antenna and first functional module 20, multiplexing main antenna realizes different wearable device 100's different functions, has greatly improved wearable device 100's space utilization, can compromise the miniaturization and the pluralism of equipment simultaneously, and reduce cost promotes the user and uses experience.

In the present invention, the wearable device 100 may be an intelligent wearable product such as smart glasses, a smart watch, a smart bracelet, and the like. In the following embodiments of the present invention, smart glasses may be specifically described as the wearable device 100, where, as shown in fig. 1, the smart glasses include a frame and a temple 11, where, referring to fig. 2, the frame is used as the device main body 10, the first functional module 20 and the coil 30 are disposed in the frame (the device main body 10), the first functional module 20 may be a wireless charging module, and the first functional module 20 is an example of a wireless charging module, the first functional module 20 has a wireless charging circuit therein, and when the coil 30 is in the first state, the coil 30 is connected to the wireless charging circuit, so that the wearable device 100 can be wirelessly charged.

In the conventional wearable device 100, taking smart glasses as an example, the glasses main body (device main body 10) is usually separated from the battery of the smart glasses, because the battery has a heavy weight, by separating the battery from the smart glasses, the weight of the smart glasses can be reduced, and the wearing weight of the user can be reduced. But after battery and the separation of intelligent glasses, when the intelligent glasses electric quantity exhausts, need additionally carry the battery and charge to intelligent glasses, it is inconvenient to use. Of course, current intelligent glasses also can set up a little battery in the glasses main part, satisfy the power consumption demand, but little battery capacity is low, and the continuation of the journey is short, can reduce user's use experience equally.

By switching the first state and the second state of the coil 30, when the wearable device 100 is not used or the electric quantity is exhausted, the coil 30 can be directly switched to the first state, so that the function of the first function module 20 (for example, a wireless charging module) is realized, and the wearable device 100 is rapidly charged. When the wearable device 100 is used normally, the coil 30 can be switched to the second state, and the coil 30 forms a main antenna, so that normal communication of the wearable device 100 can be realized. Through being integrated as an organic whole with main antenna and first functional module 20, multiplexing main antenna realizes different wearable device 100's different functions, has greatly improved wearable device 100's space utilization, can compromise the miniaturization and the pluralism of equipment simultaneously, and reduce cost promotes the user and uses experience.

It should be noted that the switching of the coil 30 between the first state and the second state may be realized by folding or unfolding the temple 11 of the smart glasses, and when the temple 11 of the smart glasses is folded, the coil 30 may be in the first state. When the temple 11 is unfolded, the coil 30 may be in the second state. Of course, the first state and the second state of the coil 30 can be realized by signal detection in a touch manner or other manners, and detailed description thereof is omitted in the present invention.

Thus, according to the wearable device 100 of the embodiment of the present invention, the coil 30 is disposed in the device body 10, the coil 30 can form a current path with the first functional module 20 in the first state to realize the corresponding function of the first functional module 20, and the coil 30 can constitute the main antenna in the second state to realize the normal communication of the wearable device 100. Through being integrated as an organic whole with main antenna and first functional module 20, multiplexing main antenna realizes different wearable device 100's different functions, has greatly improved wearable device 100's space utilization, can compromise the miniaturization and the pluralism of equipment simultaneously, and reduce cost promotes the user and uses experience.

According to one embodiment of the invention, the coil 30 is loaded with lumped capacitors 41 in a first position, a second position and a third position, respectively, the coil 30 forming a primary antenna ground point 33 in the first position, the coil 30 forming a primary antenna feed point 34 in the second position and the coil 30 forming a primary antenna tuning switch 35 in the third position.

That is, as shown in fig. 2, the coil 30 may load the lumped capacitors 41 at different positions, for example, the lumped capacitors 41 may be loaded on the first position, the second position and the third position of the coil 30, respectively (the first position, the second position and the third position are respectively referred to as E, F and G in fig. 2), the coil 30 may form the main antenna ground point 33 at the first position, the coil 30 may form the main antenna feed point 34 at the second position, and the coil 30 may form the main antenna tuning switch 35 at the third position, thereby enabling the main antenna to have different frequency band signals. And can adjust the main antenna through main antenna coordination switch and correspond the required different frequency channels of wearable equipment 100, realize the user demand of the different frequency channels of wearable equipment 100, reach the purpose of multiplexing main antenna, further reduce the required space that sets up of wearable equipment 100, satisfy the miniaturization of wearable equipment 100, lightweight demand, promote user's use and experience.

Alternatively, as shown in fig. 5, the coil 30 may be provided with metal plates 42 at the first position, the second position, and the third position, respectively. The coil 30 forms a primary antenna ground point 33 at a first location, the coil 30 forms a primary antenna feed point 34 at a second location, and the coil 30 forms a primary antenna tuning switch 35 at a third location. The coupling between the metal plates 42 forms a distributed capacitance, and the coupling between the metal plates 42 may be equivalent to loading the lumped capacitance 41 on the coil 30.

According to an embodiment of the present invention, the length of the first coil body 31 is greater than the length of the second coil body 32, and a double-branch switch tuned antenna is formed among the first position, the second position and the third position when the coil 30 is in the second state.

In other words, as shown in fig. 3, when the first coil body 31 and the second coil body 32 are unfolded, the length of the first coil body 31 is greater than that of the second coil body 32, and when the coil 30 is in the second state, the first coil body 31 and the second coil body 32 are disconnected, and a dual-branch switch tuned antenna is formed among the first position, the second position, and the third position. The tuning antenna of the dual-branch switch may be an Inverted-F antenna (IFA). At this time, the first loop body 31 is longer than the second loop body 32, and the resonance points of the two branches are close to each other, so that the working bandwidth of the main antenna can be expanded. At this time, the working frequency band of the main antenna can be adjusted to a required frequency band from different positions of the first position, the second position and the third position on the coil 30, which may be a Global System for Mobile Communication (GSM), a Wideband Code Division Multiple Access (WCDMA), a Long Term Evolution (LTE), a New air interface (New Radio, NR), a wireless network (WIFI), a Bluetooth (Bluetooth), and the like. Of course, the first position, the second position and the third position on the coil 30 may be specifically set according to actual needs, and are not described in detail in the present invention.

According to an embodiment of the present invention, a first switch 71 is disposed between the first ring body 31 and the second ring body 32, and when the first switch 71 is closed, the coil 30 is in the first state, and when the first switch 71 is open, the coil 30 is in the second state.

That is, as shown in fig. 2 and 5, a first switch 71 may be disposed between the first ring body 31 and the second ring body 32, and the first switch 71 may be a single-pole single-throw switch, and the on/off state between the first ring body 31 and the second ring body 32 is controlled by the single-pole single-throw switch. When the first switch 71 is closed, the coil 30 is in the first state, and a current path is formed between the coil 30 and the first functional module 20. When the first switch 71 is turned off, the coil 30 is in the second state, the first coil body 31 and the second coil body 32 are turned off, and the coil 30 constitutes a main antenna.

According to an embodiment of the invention, the wearable device 100 further comprises: a second functional module 50, wherein a second switch 72 is arranged between the first ring body 31 and the second ring body 32, and when the second switch 72 is closed, the first ring body 31, the second ring body 32 and the first functional module 20 form a current path; alternatively, the first ring body 31, the second ring body 32 and the second functional module 50 form a current path.

In other words, as shown in fig. 4 and 6, the wearable device 100 may further include the second functional module 50, and the functions of the second functional module 50 and the first functional module 20 may be different, so as to implement different functions. A second switch 72 may be disposed between the first ring body 31 and the second ring body 32, and the second switch 72 may be a double-pole double-throw switch. The first functional module 20 and the second functional module 50 can be switched by a double pole double throw switch, so that different functions can be switched. Under the condition that the second switch 72 is closed, if the second switch 72 is switched to be connected with the first functional module 20, the first ring body 31, the second ring body 32 and the first functional module 20 form a current path, and the corresponding function of the first functional module 20 is realized. Alternatively, when the second switch 72 is switched to connect with the second functional module 50, the first ring body 31, the second ring body 32 and the second functional module 50 form a current path, so as to implement the function of the second functional module 50.

In some embodiments of the invention, the wearable device 100 further comprises: in the third functional module 60, a third switch 73 is provided between the first ring body 31 and the second ring body 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, respectively. When the first functional module 20, the second functional module 50 or the third functional module 60 operates, the operating frequency of the coil 30 is different.

That is, as shown in fig. 7, the wearable device 100 may further include a third functional module 60, a third switch 73 may be disposed between the first ring body 31 and the second ring body 32, and the third switch 73 may be a double-pole triple-throw switch. The first functional module 20, the second functional module 50 and the third function can be switched by the double-pole-three-throw switch, so that different functions can be switched. In a case where the third switch 73 is closed, if the third switch 73 is switched to be connected to the first functional module 20, the first and

second ring bodies

31 and 32 form a current path with the first functional module 20, and a function corresponding to the first functional module 20 is implemented. Alternatively, when the third switch 73 is switched to connect with the second functional module 50, the first ring body 31, the second ring body 32 and the second functional module 50 form a current path, and the function of the second functional module 50 is realized. Or when the third switch 73 is switched to connect with the third functional module 60, the first ring body 31, the second ring body 32 and the third functional module 60 form a current path to realize the function of the third functional module 60. When the first functional module 20, the second functional module 50, or the third functional module 60 works, the operating frequency of the coil 30 is different, so that different functions of the wearable device 100 can be realized.

According to an 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.

That is, referring to fig. 2, 4, 5, 6 and 7, the first functional module 20 may be a wireless charging module having a wireless charging circuit therein. As shown in fig. 4, 6 and 7, the second functional module 50 may be a Near Field Communication (NFC) module having an NFC circuit therein. As shown in fig. 7, the third functional module 60 may be a cellular antenna module having a cellular antenna feed point therein.

As shown in fig. 2 and 5, when the first function module 20 (wireless charging module) is provided in the apparatus main body 10, a single-pole single-throw switch is loaded at the junction of the first ring body 31 and the second ring body 32 of the coil 30 to control the on-off state between the first ring body 31 and the second ring body 32. Lumped capacitors 41 are loaded between different positions of the coil 30, and are equivalently in an on state in a main antenna frequency band and in an off state in an NFC frequency band. When the single-pole single-throw switch is in a conducting state, the first ring body 31 and the second ring body 32 are communicated to form a closed coil 30, and at the moment, a wireless charging circuit in the wireless charging module works to realize a wireless charging function. When the single pole single throw switch is in the off state, the first coil body 31 and the second coil body 32 are disconnected, forming a main antenna. The first position, the second position and the third position on the coil 30 form a double-branch switch tuned IFA antenna, at this time, the length of the first loop body 31 is longer than that of the second loop body 32, and the resonance points of the two branches are close to each other, so that the working bandwidth of the main antenna can be expanded. The working frequency band of the main antenna can be adjusted to the required frequency band by the first position, the second position and the third position on the coil 30, and can be GSM, WCDMA, LTE, NR, WIFI, bluetooth and the like. The principles of operation of antennas, cellular antennas, etc. are understood and can be implemented by those skilled in the art and will not be described in detail herein.

As shown in fig. 4 and 6, when the first functional module 20 (wireless charging module) and the second functional module 50 (NFC module) are provided in the device body 10, the coil 30 may be switched to different circuits by using a double-pole double-throw switch, so that the NFC function and the wireless charging function may be switched. By taking the intelligent glasses as an example, the wireless charging function can be awakened after the glasses are taken off (the glasses legs 11 are folded) according to the actual use scene of the user, and the wireless charging function is placed on a specific slave electric appliance for quick charging. Awakening the NFC function when wearing the glasses (the unfolded glasses legs 11) can be used for quick connection between the intelligent glasses and other equipment.

As shown in fig. 7, when the first functional module 20 (wireless charging module), the second functional module 50 (NFC module), and the third functional module 60 (cellular antenna) are provided in the device body 10, the coil 30 may be switched to different circuits by one double pole, triple throw switch. When the double-pole triple-throw switch is switched to the NFC circuit, the NFC function can be achieved, and when the double-pole triple-throw switch is switched to the wireless charging circuit, the wireless charging function can be achieved. When the double-pole triple-throw switch is switched to the feed of the honeycomb antenna, the honeycomb antenna function can be realized.

As shown in fig. 8 and 9, the two port states of the cellular antenna can be set as one port connected to a matched load 81 (adjusted to a non-reflection state) or a ground 82, and the other port connected to a power feed 83. When a port is connected to a matched load 81, the coil 30 is now a travelling wave antenna (see figure 8). When one is in the grounded 82 state, the coil 30 is a standing wave antenna (see fig. 9). As shown in fig. 10, the current direction of the traveling wave antenna is the arrow direction, and when t =0, the AC point "open circle" represents the current node point, and the BD point "closed circle" represents the current anti-node point. As shown in fig. 11, when T = T/4, the current direction also changes, and at this time, the AC point becomes the current anti-node point and the BD point becomes the current node point. The current direction change can cause the polarization of the electromagnetic wave in the far-field region to change, so that the traveling wave antenna can radiate circularly polarized waves and can be used as a GPS positioning antenna. As shown in fig. 12, the current direction of the standing wave antenna is an arrow direction, the AC point "open circle" represents a current antinode, the BD point "solid circle" represents a current node, and the current directions are all from bottom to top, and the standing wave antenna is equivalent to a single-stage sub (monopole) antenna, and by adding matching adjustment impedance at the other port feeding portion 83, functions of GSM, WCDMA, LTE, NR, WIFI, bluetooth antenna and the like can be realized, and specifically, in which frequency band the standing wave antenna works, matching adjustment can be performed according to the length of the coil 30.

The design scheme of the invention can solve the problem of short endurance, and the wireless charging function is added to the glasses, so that a user can wirelessly charge after taking off the glasses. Meanwhile, in order to solve the problems of space and light weight, the wireless charging module, the NFC module and the main antenna are integrated into a whole. After the glasses are taken off (the glasses legs 11 are folded), the wireless charging function can be awakened, and the glasses can be placed on a specific slave appliance for quick charging. When the glasses are worn (the glasses legs 11 are not folded), the NFC function can be awakened, and the NFC function can be used for quick connection between the intelligent glasses and other equipment; awaken the main function simultaneously when wearing glasses (not folding mirror leg 11), realize intelligent glasses's normal communication. The invention reuses three antennas, greatly improves the space utilization rate and reduces the cost.

In the present invention, the antenna structure is in the form of a coil 30, and may be implemented by LCP, FPC, LDS, or other processes. The switch form can be a PIN switch and also can be a MEMS switch. The number of turns of the coil 30 may be one, two, three or more. The main antenna may be in the form of an IFA, monopole antenna, DIPOLE (DIPOLE) antenna, or the like.

In some embodiments of the present invention, as shown in fig. 2 and 4, the first ring body 31 and the second ring body 32 are spaced apart from each other in the horizontal direction of the apparatus body 10. Taking smart glasses as an example, the first ring body 31 and the second ring body 32 may be arranged to extend along a plane of the frame. As shown in fig. 5 to 7, the first ring body 31 and the second ring body 32 may be spaced apart in the thickness direction of the device main body 10, for example, the first ring body 31 and the second ring body 32 may be spaced apart in the thickness direction of the rim, so as to form the coil 30 into a three-dimensional structure. By routing the lines in the thickness direction of the frame, the capacitance between the first ring 31 and the second ring 32 can be realized by distributed capacitance. The coil 30 is formed by routing in the thickness direction of the apparatus main body 10, so that the size in the plane direction is saved, and the coil is suitable for the case where the size layout in the plane direction is tight. On the other hand, the ground coupling, feeding and tuning of the first ring body 31 and the second ring body 32 can be realized by using distributed capacitance, so that the cost is saved.

In some embodiments of the present invention, the number of the coils 30 is two, and two coils 30 are spaced apart from each other 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.

That is, the number of the coils 30 is two. Two coils 30 are spaced apart within the device body 10, one coil 30 corresponding to a first functional module 20, and the other coil 30 corresponding to a first functional module 20 and a second functional module 50. Taking the smart glasses as an example, the left and right frames may be respectively provided with a coil 30. A coil 30 is loaded on the left eye frame, as shown in fig. 2 and 5, a single pole single throw switch is loaded at the junction of a first coil body 31 and a second coil body 32 of the coil 30, and is used for controlling the on-off state between the first coil and the second coil 30. And a coil 30 is loaded on the right eyeglass frame, and as shown in fig. 4 and fig. 6, the conversion between the NFC function and the wireless charging function can be realized by switching to different circuits through a double-pole double-throw switch. According to the actual use scene of a user, the wireless charging function is awakened after the glasses are taken off (the glasses legs 11 are folded), and the wireless charging function is placed on a specific slave electric appliance for quick charging. Awakening the NFC function when wearing the glasses (the unfolded glasses legs 11) can be used for quick connection between the intelligent glasses and other equipment.

Of course, other structures and operating principles of the wearable device 100 are understood and can be implemented by those skilled in the art, and are not described in detail herein.
