For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0062] The following will be described in detail Figures 1-12 An intelligent glasses according to an embodiment of the present application is described.
[0063] As Figure 1 and Figure 2 The intelligent glasses according to some embodiments of the present application, as shown, include a glasses body 100, a glasses leg 200 and an antenna unit 300.
[0064] The glasses body 100 is rotatably connected with the glasses leg 200. For example, a hinge or a spherical connecting piece is arranged between the glasses body 100 and the glasses leg 200, and based on the hinge or the spherical connecting piece, the rotatable connection of the glasses body 100 and the glasses leg 200 can be conveniently realized under the manual operation of the user.
[0065] Further, the antenna unit 300 includes a first antenna 31 and a second antenna 32, the first antenna 31 is arranged on the glasses body 100, and the second antenna 32 is arranged on the glasses leg 200, the first antenna 31 or the second antenna 32 is used to be electrically connected with a feeding circuit on the intelligent glasses. Wherein, the glasses body 100 shown in the embodiment includes a glasses frame 11 and a glasses lens 12, the glasses lens 12 is mounted on the glasses frame 11, and the glasses leg 200 is rotatably mounted on the glasses frame 11, so that the first antenna 31 can be arranged on the glasses frame 11 and the second antenna 32 can be arranged on the glasses leg 200 and extend along the length direction of the glasses leg 200 in the embodiment.
[0066] Wherein, the first antenna 31 of the embodiment can be arranged in the glasses frame 11 or on the surface of the glasses frame 11. The second antenna 32 of the embodiment can be arranged in the glasses leg 200 or on the surface of the glasses leg 200, which is not specifically limited.
[0067] At the same time, the feeding circuit is used to emit radio frequency signals to the first antenna 31 or the second antenna 32, and the feeding circuit can be arranged on the glasses body 100 or on the glasses leg 200, which is not specifically limited.
[0068] In order to facilitate the user to wear, the glasses leg 200 of the embodiment of the present application is usually provided with two, one of which is rotatably connected with one end of the glasses frame 11, and the other is rotatably connected with the other end of the glasses frame 11.
[0069] Further, the smart glasses of the embodiments of the present application have a folded state and an unfolded state. When the smart glasses are in the folded state, the first antenna 31 is separated from the second antenna 32; when the smart glasses are in the unfolded state, the first antenna 31 is electrically connected with the second antenna 32.
[0070] By separating the first antenna 31 and the second antenna 32 on the glasses body 100 and the temple 200, the embodiments of the present application can match the working state of the antenna unit 300 with the actual use scenario of the smart glasses by using the rotating connection feature of the glasses body 100 and the temple 200.
[0071] When the use scenario of the smart glasses is that the user takes off the smart glasses, the smart glasses are only used as a communication device. In this state, the head of the user does not support the temple 200 of the smart glasses, and the smart glasses are in the folded state, so that the first antenna 31 and the second antenna 32 are separated from each other, the effective radiation length of the antenna unit 300 corresponds to the length of the first antenna 31 or the second antenna 32, and the antenna unit 300 works at the corresponding resonant frequency of the first antenna 31 or the second antenna 32.
[0072] When the use scenario of the smart glasses is that the user wears the smart glasses, the smart glasses are used as both a communication device and a vision correction device, so that the use scenario of the smart glasses and the corresponding communication demand change. In this state, the head of the user supports the temple 200 of the smart glasses, and the smart glasses are in the unfolded state, so that the first antenna 31 and the second antenna 32 are connected, the effective radiation length of the antenna unit 300 is equal to the total length of the first antenna 31 and the second antenna 32, and the antenna unit 300 works at the corresponding resonant frequency of the combined antenna formed by the first antenna 31 and the second antenna 32.
[0073] Therefore, the embodiments of the present application realize the arrangement of the antenna unit 300 based on the structural features of the smart glasses. Compared with the existing antenna tuning mode using an electronic switch, the embodiments of the present application can match the working state of the antenna unit with the actual use scenario of the smart glasses, and conveniently realize the frequency tuning of the antenna unit 300 in a mechanical control mode, without the need to additionally configure an electronic switch and an accompanying control circuit on the smart glasses, thereby reducing the occupation of the antenna unit 300 on the limited layout area of the smart glasses, and realizing the miniaturization and lightweight design of the smart glasses.
[0074] In some examples, as Figure 2As shown, in order to facilitate the state switching control of the first antenna 31 and the second antenna 32 based on the smart glasses, the glasses body 100 shown in the embodiment is provided with a connecting portion 13; the connecting portion 13 is rotationally connected with the temple 200; the first end of the first antenna 31 is arranged at the first end of the connecting portion 13, and the first end of the second antenna 32 is arranged at the first end of the temple 200.
[0075] In the case that the smart glasses are in the folded state, the first end of the connecting portion 13 is away from the first end of the temple 200, so that the first end of the first antenna 31 is separated from the first end of the second antenna 32.
[0076] In the case that the smart glasses are in the unfolded state, the first end of the connecting portion 13 is close to the first end of the temple 200, so that the first end of the first antenna 31 is electrically connected with the first end of the second antenna 32.
[0077] In the embodiment, the first end of the connecting portion 13 has a first end face, the first end of the temple 200 has a second end face, the first end of the first antenna 31 can be arranged on the first end face of the connecting portion 13 or partially protrude from the first end face of the connecting portion 13, and the first end of the second antenna 32 can be arranged on the second end face of the temple 200 or partially protrude from the second end face of the temple 200.
[0078] Correspondingly, when the smart glasses are in the folded state, the first end face of the connecting portion 13 is away from the second end face of the temple 200 and is vertically distributed, so that the first end of the first antenna 31 cannot be kept in the electrically connected state with the first end of the second antenna 32.
[0079] In the case that the smart glasses are in the unfolded state, the first end face of the connecting portion 13 is close to the second end face of the temple 200 and is inlaid or parallelly distributed, so that the first end of the first antenna 31 can be in the electrically connected state with the first end of the second antenna 32.
[0080] In some examples, as Figure 2 As shown, in order to facilitate the on-off state control between the first end of the first antenna 31 and the first end of the second antenna 32 according to the working state of the smart glasses, the antenna unit 300 shown in the embodiment further includes a conductive component 33; the conductive component 33 is arranged between the first end of the connecting portion 13 and the first end of the temple 200. For example, a gap is arranged between the first end of the connecting portion 13 and the first end of the temple 200, the conductive component 33 is located in the gap, and the first end of the connecting portion 13 or the first end of the temple 200 is electrically connected with the conductive component 33.
[0081] In the folded state of the smart glasses, the first end of the first antenna 31 and the first end of the second antenna 32 are disconnected due to the first end of the connecting part 13 being away from the first end of the temple 200. At this time, the first antenna 31 and the second antenna 32 are not in an electrically connected state.
[0082] In the unfolded state of the smart glasses, the first end of the first antenna 31 and the first end of the second antenna 32 are electrically connected through the conductive assembly 33 due to the first end of the connecting part 13 being close to the first end of the temple 200.
[0083] Therefore, the conductive assembly 33 of the embodiment of the present application can conveniently control the electrically connected state between the first end of the first antenna 31 and the first end of the second antenna 32 according to the switching of the folded state and the unfolded state of the smart glasses.
[0084] Obviously, the arrangement of the conductive assembly 33 of the embodiment of the present application will not affect the normal use of the smart glasses. The conductive assembly 33 can be a conductive column, a conductive spring, a mechanical switching switch, etc., which is not specifically limited here.
[0085] In some examples, as shown in Figure 3 and Figure 4 , the antenna unit 300 of the embodiment of the present application can be configured as a monopol antenna (single-stage antenna). In addition to the first antenna 31 and the second antenna 32 shown in the above embodiment, the antenna unit 300 is also provided with a first ground plate 34.
[0086] The first ground plate 34 is provided on the glasses body 100 and is isolated from the first antenna 31, and the first antenna 31 is electrically connected to the feed circuit provided on the glasses body 100.
[0087] Alternatively, the first ground plate 34 is provided on the temple 200 and is isolated from the second antenna 32, and the second antenna 32 is electrically connected to the feed circuit provided on the temple 200.
[0088] It should be pointed out here that the position of the first ground plate 34 shown in the embodiment of the present application is determined by the position of the feed circuit corresponding to the monopol antenna. The feed circuit is not specifically shown in Figure 3 and Figure 4 .
[0089] For example, when the feed circuit is provided on the glasses body 100, the first ground plate 34 is provided on the glasses body 100. At this time, the second end of the first antenna 31 is electrically connected to the feed circuit on the glasses body 100, and the first ground plate 34 is common with the feed circuit.
[0090] Correspondingly, when the feeding circuit is arranged on the temple 200, the first ground plate 34 is arranged on the temple 200. At this time, the second end of the second antenna 32 is electrically connected with the feeding circuit on the temple 200, and the first ground plate 34 is in common ground with the feeding circuit.
[0091] In some examples, in order to facilitate the control of the electrical connection state of the first end of the first antenna 31 and the first end of the second antenna 32 according to the working state of the smart glasses, the conductive assembly 33 shown in the embodiment includes an elastic conductive piece 331, which includes a copper sheet, an iron sheet or conductive foam, etc.
[0092] One of the first end of the first antenna 31 and the first end of the second antenna 32 is electrically connected with the elastic conductive piece 331, and the other of the first end of the first antenna 31 and the first end of the second antenna 32 is in abutment or separation with the elastic conductive piece 331.
[0093] As shown in Figure 2 , Figure 3 and Figure 4 , the first antenna 31 of the embodiment of the application is electrically connected with the feeding circuit arranged on the glasses body 100, the first ground plate 34 is arranged on the glasses body 100 and is in common ground with the feeding circuit. The elastic conductive piece 331 of the embodiment is arranged on the temple 200, and the first end of the second antenna 32 is electrically connected with one end of the elastic conductive piece 331.
[0094] When the user takes off the smart glasses, because the head of the user does not support the temple 200 of the smart glasses, the temple 200 can be parallel to the frame 11, that is, the smart glasses are in a folded state. At this time, the other end of the elastic conductive piece 331 located on the temple 200 cannot be electrically connected with the first end of the first antenna 31, the first antenna 31 and the second antenna 32 are in a separated state, the effective radiation length of the antenna unit 300 is the length of the first antenna 31, denoted as L1, and the resonant frequency of the antenna unit 300 falls at f1. Assuming that f1 is the wifi frequency band, in the application scenario that the user takes off the smart glasses, the user is in a resting state indoors, and the use frequency of wifi is higher when surfing the Internet, so the user can surf the Internet by using the frequency band provided by the first antenna 31.
[0095] When the user wears the smart glasses, the temple 200 can be supported by the head of the user to be perpendicular to the frame 11, i.e., the smart glasses are in an unfolded state, because the head of the user supports the temple 200 of the smart glasses. At this time, the first end of the first antenna 31 abuts against the other end of the elastic conductive piece 331, so that the electrical connection is formed between the first end of the first antenna 31 and the first end of the second antenna 32, the effective radiation length of the antenna unit 300 is the total length of the first antenna 31 and the second antenna 32, denoted as L1+L2, and the resonance frequency of the antenna unit 300 falls in f2. Obviously, f2>f1, and by reasonably designing the length of L2, the resonance frequency of f2 can correspond to the GPS L1 or WWAN frequency band, so as to facilitate the user to navigate or surf the Internet.
[0096] In addition, the embodiment can also cooperate with the antennas of the rest of the smart glasses, when the user takes off the smart glasses, the resonance frequency of the antenna unit 300 falls in the frequency band corresponding to the wifi mimo, so as to improve the uplink and downlink rates of wifi, and after the user wears the smart glasses, the resonance frequency of the antenna unit 300 falls in the combined frequency band corresponding to GPS and wifi, so as to expand the communication frequency band of the smart glasses.
[0097] Based on the scheme shown in the above embodiment, as Figure 3 and Figure 4 shown, in order to ensure the reliability of the electrical connection between the first end of the first antenna 31 and the other end of the elastic conductive piece 331, the first end of the first antenna 31 can be electrically connected to the first conductive gasket 311, and the first conductive gasket 311 is arranged on the first end surface of the connecting portion 13. The first conductive gasket 311 can be a gold-plated gasket.
[0098] At the same time, in order to prevent the metal structure from affecting the operation of the antenna unit 300, the smart glasses shown in the embodiment include an insulating hinge piece 400, one end of the insulating hinge piece 400 is connected to the connecting portion 13, and the other end of the insulating hinge piece 400 is connected to the temple 200, and based on the insulating hinge piece 400, the hinge connection between the glasses body 100 and the temple 200 can be realized.
[0099] The insulating hinge piece 400 includes a first hinge portion, a second hinge portion, and a hinge pin. One end of the first hinge portion is connected to the connecting portion 13, the other end of the first hinge portion is hingedly connected to one end of the second hinge portion through the hinge pin, and the other end of the second hinge portion is connected to the temple 200.
[0100] In some examples, as Figures 5 to 8 shown, the antenna unit 300 of the embodiment can be configured as an IFA antenna. In the embodiment, the feeding circuit corresponding to the antenna unit 300 is arranged on the temple 200.
[0101] Therefore, the antenna unit 300 shown in this embodiment further includes a second ground plane 35, a third ground plane 36, and a first conductive element 41. The conductive component 33 includes a mechanical switch 333, which is disposed on the temple 200. The mechanical switch 333 can be a single-pole double-throw switch or a double-pole double-throw switch.
[0102] The second base plate 35 is disposed on the main body 100 of the glasses, and the third base plate 36 is disposed on the temple 200. The second base plate 35 and the third base plate 36 are electrically connected through the first conductive member 41. The first conductive member 41 can be a conductive flexible connector or a conductive hinge disposed between the connecting part 13 and the temple 200. It is not specifically limited here. As long as it is a conductive structure that does not affect the rotation of the temple 200 relative to the main body 100 of the glasses and realizes the electrical connection between the second base plate 35 and the third base plate 36, it meets the design requirements.
[0103] Meanwhile, the first end of the second ground 35 is located at the first end of the connecting part 13; the first end of the third ground 36 is located at the first end of the temple 200; the second end of the first antenna 31 is electrically connected to the second end of the second ground 35, and the second antenna 32 is electrically connected to the feed circuit located on the temple 200.
[0104] In actual deployment, this embodiment can extend the second ground plane 35 along the extension direction of the first antenna 31 and be spaced apart from the first antenna 31. Simultaneously, this embodiment can electrically connect the second end of the second antenna 32 to the feed circuit on the temple 200. The third ground plane 36 extends along the extension direction of the second antenna 32 and is spaced apart from the second antenna 32; the second end of the third ground plane 36 is connected to the ground terminal of the feed circuit.
[0105] like Figure 5 and Figure 6 As shown, when the smart glasses are in a folded state, since the first end of the connecting part 13 is far from the first end of the temple 200, the mechanical switch 333 is in its initial state, and the first end of the second antenna 32 is electrically connected to the first end of the third ground plane 36 through the mechanical switch 333. At this time, the effective radiation length of the antenna element 300 is L2, and the effective radiator of the antenna element 300 includes the second antenna 32, the conductive component 33, and the third ground plane 36, which forms an IFA antenna. In this case, the antenna element 300 can operate in a 1 / 4 wavelength mode with a resonant frequency of f0, and has high radiation efficiency and communication capability.
[0106] like Figure 7 and Figure 8As shown, when the smart glasses are in the unfolded state, the first end of the connecting portion 13 is close to the first end of the temple 200, and the first end of the connecting portion 13 and the first end of the temple 200 will trigger the mechanical switch 333 in the process of approaching, causing the mechanical switch 333 to switch the switch state, so that the first end of the first antenna 31 and the first end of the second antenna 32 are electrically connected through the mechanical switch 333. At this time, the effective radiation length of the antenna unit 300 is L1+L2, and the effective radiator of the antenna unit 300 includes the first antenna 31, the second antenna 32, the second ground plate 35, the third ground plate 36, and the fourth ground plate 37 arranged on the glasses body 100, which forms an IFA antenna. Among them, the first antenna 31 and the second antenna 32 are integrated, and the second ground plate 35, the third ground plate 36, and the fourth ground plate 37 are integrated.
[0107] In actual application, by designing L1 to be approximately twice the length of L2, the resonant frequency of the antenna unit 300 shown in the embodiment is f0, which works in 3 / 4 wavelength mode. At this time, the efficiency of the antenna unit 300 is slightly low, but based on the reverse current formed on the first antenna 31 and the second antenna 32 when the IFA antenna works, the user's absorption of the radiation energy of the antenna unit 300 is low, that is, the SAR value is reduced, and the harm of electromagnetic radiation to the user is reduced.
[0108] In some examples, as shown in Figure 6 and Figure 8 The conductive assembly 33 of the embodiment of the application also includes an elastic member 332. The mechanical switch 333 includes a conductive support 3331 and a conductive blade 3332; the conductive support 3331 is electrically connected with the second antenna 32, and the middle part of the conductive blade 3332 is rotatably arranged on the conductive support 3331, so that the conductive blade 3332 can be electrically connected with the conductive support 3331 while rotating relative to the conductive support 3331.
[0109] At the same time, the elastic member 332 is arranged between the first end of the conductive blade 3332 and the first end of the temple 200; the elastic member 332 has a first state and a second state. Among them, the deformation amount of the elastic member 332 in the second state is greater than the deformation amount of the elastic member 332 in the first state, and the elastic member 332 can be a spring.
[0110] In the case that the smart glasses are in the folded state, the first end of the first antenna 31 is separated from the first end of the conductive blade 3332, so that the elastic member 332 is in the first state, and the second end of the conductive blade 3332 abuts against the first end of the third ground plate 36.
[0111] In the unfolded state of the smart glasses, the first end of the first antenna 31 abuts against the first end of the conductive blade 3332, so that the elastic member 332 is in the second state, and the second end of the conductive blade 3332 is suspended between the second floor 35 and the third floor 36.
[0112] In some examples, the first state of the elastic member 332 can be understood as the elastic member 332 being in a natural elongation state, and the second state of the elastic member 332 can be understood as the elastic member 332 being in a compressed state.
[0113] In this way, when the smart glasses are in the folded state, the elastic member 332 is in the first state because the connecting part 13 and the temple 200 do not exert a force on the elastic member 332. With the cooperation of the elastic member 332, it can be ensured that the mechanical switch 333 is in the initial state, and the second antenna 32 and the third floor 36 are electrically connected through the mechanical switch 333.
[0114] When the smart glasses are in the unfolded state, the first end of the conductive blade 3332 is driven to rotate relative to the conductive support 3331 toward one side of the temple 200 in the process of approaching the connecting part 13 and the temple 200, so that the first antenna 31 and the second antenna 32 are electrically connected through the mechanical switch 333 according to the state switching of the mechanical switch 333, and the second end of the conductive blade 3332 is disconnected from the second floor 35 and the third floor 36, respectively.
[0115] Since the elastic member 332 switches from the first state to the second state when the smart glasses are in the unfolded state, the elastic member 332 stores a certain elastic potential energy, so that when the smart glasses switch from the unfolded state to the folded state, the mechanical switch 333 will automatically return to the initial state under the drive of the elastic member 332.
[0116] As shown in Figure 6 As shown in Figure 8 To ensure the reliability of the electrical connection between the first end of the conductive blade 3332 and the first end of the first antenna 31, the first end of the first antenna 31 is electrically connected to the second conductive pad 312 in the embodiment.
[0117] To ensure the reliability of the electrical connection between the second end of the conductive blade 3332 and the first end of the third floor 36, the first end of the third floor 36 is electrically connected to the third conductive pad 361, and the first insulating pad 351 is arranged at the first end of the second floor 35.
[0118] The second conductive pad 312 and the third conductive pad 361 can be gold-plated pads, and the first insulating pad 351 can be a plastic pad.
[0119] Based on the scheme shown in the above embodiment, as shown in Figures 9 to 12As shown, in the case that the feeding circuit corresponding to the antenna unit 300 is arranged on the glasses body 100, the antenna unit 300 can also be configured as another form of IFA antenna.
[0120] To this end, the antenna unit 300 shown in the embodiment further comprises a second ground plate 35, a third ground plate 36 and a second conductive member 42. The conductive assembly 33 comprises a mechanical switch 333 arranged on the glasses body 100. The mechanical switch 333 can be a single-pole double-throw switch or a double-pole double-throw switch.
[0121] The second ground plate 35 is arranged on the glasses body 100, and the third ground plate 36 is arranged on the temple 200. The second ground plate 35 and the third ground plate 36 are electrically connected through the second conductive member 42. The second conductive member 42 can be a conductive flexible connection or a conductive hinged member arranged between the connecting portion 13 and the temple 200, which is not limited here, as long as the conductive structure does not affect the rotation of the temple 200 relative to the glasses body 100 and realizes the electrical connection between the second ground plate 35 and the third ground plate 36, which meets the design requirements.
[0122] At the same time, the first end of the second ground plate 35 is arranged at the first end of the connecting portion 13, and the first end of the third ground plate 36 is arranged at the first end of the temple 200. The first antenna 31 is electrically connected with the feeding circuit arranged on the glasses body 100, and the second end of the second antenna 32 is electrically connected with the second end of the third ground plate 36.
[0123] In actual arrangement, the second ground plate 35 can be extended along the extension direction of the first antenna 31 and arranged spaced apart from the first antenna 31. The second end of the first antenna 31 is electrically connected with the feeding circuit on the glasses body 100, and the second end of the second ground plate 35 is connected with the ground end of the feeding circuit.
[0124] At the same time, the third ground plate 36 can be extended along the extension direction of the second antenna 32 and arranged spaced apart from the second antenna 32.
[0125] As shown in Figure 9 and Figure 10 When the smart glasses are in the folded state, the first end of the connecting portion 13 is away from the first end of the temple 200, the mechanical switch 333 is in the initial state, and the first end of the first antenna 31 is electrically connected with the first end of the second ground plate 35 through the mechanical switch 333. At this time, the effective radiation length of the antenna unit 300 is L1, and the effective radiator of the antenna unit 300 comprises the first antenna 31, the conductive assembly 33, the second ground plate 35 and the fourth ground plate 37 connected with the second ground plate 35, which forms an IFA antenna.
[0126] As shown in Figure 11 and Figure 12As shown, in the case that the smart glasses are in the unfolded state, since the first end of the connecting portion 13 is close to the first end of the temple 200, the first end of the connecting portion 13 and the first end of the temple 200 will trigger the mechanical switch 333 in the process of being close, causing the mechanical switch 333 to switch the switch state, so that the first end of the first antenna 31 and the first end of the second antenna 32 are electrically connected. At this time, the effective radiation length of the antenna unit 300 is L1+L2, and the effective radiator of the antenna unit 300 includes the first antenna 31, the second antenna 32, the third ground plate 36, the second ground plate 35, and the fourth ground plate 37 connected with the second ground plate 35, which forms an IFA antenna. Wherein, the first antenna 31 and the second antenna 32 are integrated, and the second ground plate 35, the third ground plate 36 and the fourth ground plate 37 are integrated.
[0127] In some embodiments, as shown in Figure 10 and Figure 12 As shown, the conductive assembly 33 of the embodiment of the application further includes an elastic member 332. The mechanical switch 333 includes a conductive support 3331 and a conductive blade 3332; the conductive support 3331 is electrically connected with the first antenna 31, and the middle part of the conductive blade 3332 is rotatably arranged on the conductive support 3331, so that the conductive blade 3332 can be electrically connected with the conductive support 3331 while rotating relative to the conductive support 3331.
[0128] At the same time, the elastic member 332 is arranged between the first end of the conductive blade 3332 and the first end of the connecting portion 13; the elastic member 332 has a first state and a second state. Wherein, the deformation amount of the elastic member 332 in the second state is greater than the deformation amount of the elastic member 332 in the first state, and the elastic member 332 can be a spring.
[0129] In the case that the smart glasses are in the folded state, the first end of the second antenna 32 is separated from the first end of the conductive blade 3332, so that the elastic member 332 is in the first state, and the second end of the conductive blade 3332 abuts against the first end of the second ground plate 35.
[0130] In the case that the smart glasses are in the unfolded state, the first end of the second antenna 32 abuts against the first end of the conductive blade 3332, so that the elastic member 332 is in the second state, and the second end of the conductive blade 3332 is suspended between the second ground plate 35 and the third ground plate 36.
[0131] In this way, when the smart glasses are in the folded state, since the connecting portion 13 and the temple 200 do not exert force on the elastic member 332, the elastic member 332 is in the first state. With the cooperation of the elastic member 332, it can be ensured that the mechanical switch 333 is in the initial state, and the first antenna 31 and the second ground plate 35 are electrically connected through the mechanical switch 333.
[0132] When the smart glasses are in the unfolded state, due to the connection part 13 and the temple 200 in the process of approaching, the first end of the conductive blade 3332 is driven to rotate relative to the conductive support 3331 towards the side of the glasses body 100, then according to the state switching of the mechanical switch 333, the first antenna 31 and the second antenna 32 are electrically connected through the mechanical switch 333, and the second end of the conductive blade 3332 is disconnected with the second floor 35 and the third floor 36 respectively.
[0133] Because the elastic member 332 switches from the first state to the second state when the smart glasses are in the unfolded state, the elastic member 332 stores a certain elastic potential, then under the driving of the elastic member 332, the mechanical switch 333 will automatically restore to the initial state when the smart glasses switch from the unfolded state to the folded state.
[0134] As shown in Figure 10 With Figure 12 In order to ensure the reliability of the electrical connection between the first end of the conductive blade 3332 and the first end of the second antenna 32, the first end of the second antenna 32 is electrically connected with the fourth conductive pad 321 in the embodiment. In order to ensure the reliability of the electrical connection between the first end of the conductive blade 3332 and the first end of the second floor 35, the first end of the second floor 35 is electrically connected with the fifth conductive pad 352, and the second insulating pad 362 is arranged at the first end of the third floor 36.
[0135] Among them, the fourth conductive pad 321 and the fifth conductive pad 352 are gold-plated pads, and the second insulating pad 362 is a plastic pad.
[0136] As can be seen from the above, the embodiment adaptively realizes the arrangement of the antenna unit according to the structural characteristics of the smart glasses without changing the appearance structure of the smart glasses, reduces the occupation of the antenna unit to the limited layout area on the smart glasses, matches the working state of the antenna unit with the actual use scene of the smart glasses, conveniently realizes the frequency tuning of the antenna unit, is simple and convenient to operate, and can improve the user experience.
