Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to smart glasses. Background Art

[0002] Smart glasses, as wearable devices, are in contact with the human body for extended periods, necessitating consideration of the impact of antenna radiation on the body. Glasses lack a complete floor structure, and antennas often have poor directivity. Consequently, a significant amount of radiated energy enters the body, causing the Specific Absorption Rate (SAR) to exceed standards. Summary of the Invention

[0003] The present application aims to provide a smart glasses that solves or improves one of the problems that antenna radiation has a greater impact on the human body.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, the present application provides a pair of smart glasses, comprising:

[0006] Frames;

[0007] a circuit board, provided on the frame;

[0008] A main antenna is provided on the frame and electrically connected to the circuit board. The main antenna is located on one side of the circuit board.

[0009] A parasitic antenna is provided on the frame. The parasitic antenna is located on the side of the main antenna facing away from the circuit board. The parasitic antenna includes an antenna body. The antenna body and the main antenna extend in the same direction, and the length of the antenna body is shorter than the length of the main antenna. The circuit board, the main antenna and the parasitic antenna are located on the same layer in the thickness direction of the frame.

[0010] In an embodiment of the present application, the smart glasses include a frame and a circuit board arranged on the frame, a main antenna and a parasitic antenna, wherein the main antenna is located between the parasitic antenna and the circuit board.

[0011] In addition, the parasitic antenna includes an antenna body, which is arranged side by side with the main antenna. The length of the antenna body is smaller than that of the main antenna, so that the antenna body can act as a director. That is, the circuit board can act as a transmitter, and the parasitic antenna can act as a director, thereby guiding the main radiation of the main antenna in the direction from the circuit board to the parasitic antenna. That is, the parasitic antenna is located on one side of the antenna body, and the parasitic antenna acts as a director for the antenna body. The circuit board is located on the other side of the antenna body, and the circuit board acts as a reflector for the antenna body.

[0012] In addition, the circuit board, the main antenna and the parasitic antenna are located in the same layer in the thickness direction of the frame, where the thickness direction of the frame can be understood as the direction from the human body to the outside of the human body when the human body wears smart glasses, that is, the direction from the side of the frame facing the human body to the side away from the human body. Therefore, the parasitic antenna and the circuit board cooperate to guide the radiation of the main antenna to the surrounding side of the circuit board, reducing radiation to the human body. For example: when the human body wears smart glasses, the parasitic antenna and the circuit board cooperate to guide the radiation of the main antenna forward, backward, upward and downward, etc., thereby reducing the radiation of the main antenna to the human body and improving the safety of the smart glasses.

[0031] The following combination Figures 1 to 10 The following describes smart glasses 100 according to an embodiment of the present application.

[0032] like Figure 1 、 Figure 2 and Figure 5 As shown, the present application provides a smart glasses 100, including: a frame 110; a circuit board 120, which is arranged on the frame 110; a main antenna 130, which is arranged on the frame 110 and electrically connected to the circuit board 120, and the main antenna 130 is located on one side of the circuit board 120; a parasitic antenna 140, which is arranged on the frame 110, and the parasitic antenna 140 is located on the side of the main antenna 130 away from the circuit board 120, and the parasitic antenna 140 includes an antenna body 142, and the antenna body 142 and the main antenna 130 have the same extension direction, and the length of the antenna body 142 is less than the length of the main antenna 130, wherein the circuit board 120, the main antenna 130 and the parasitic antenna 140 are located on the same layer in the thickness direction of the frame 110.

[0033] In an embodiment of the present application, the smart glasses 100 include a frame 110 and a circuit board 120, a main antenna 130, and a parasitic antenna 140 arranged on the frame 110, wherein the main antenna 130 is located between the parasitic antenna 140 and the circuit board 120, so that the circuit board 120 can act as a transmitter, and the parasitic antenna 140 can act as a director, thereby guiding the main radiation of the main antenna 130 toward the direction from the circuit board 120 to the parasitic antenna 140.

[0034] In addition, the circuit board 120, the main antenna 130 and the parasitic antenna 140 are located in the same layer in the thickness direction of the frame 110, wherein the thickness direction of the frame 110 can be understood as the direction from the human body 200 to the outside of the human body 200 when the human body 200 wears the smart glasses 100, that is, the direction from the side of the frame 110 facing the human body 200 to the side away from the human body 200. Therefore, the parasitic antenna 140 and the circuit board 120 cooperate to guide the radiation of the main antenna 130 toward the peripheral side of the circuit board 120, reducing the radiation to the human body 200. For example: when the human body 200 wears the smart glasses 100, the parasitic antenna 140 and the circuit board 120 can cooperate to guide the radiation of the main antenna 130 forward, backward, upward and downward, etc., thereby reducing the radiation of the main antenna 130 to the human body 200, reducing the SAR value, improving the antenna gain effect, and improving the safety of the smart glasses 100.

[0035] Among them, the main antenna 130 can be electrically connected to the circuit board 120. The main antenna 130 can be a dipole antenna. The parasitic antenna 140 is set on one side of the dipole antenna, and the circuit board 120 is set on the other side. Of course, the main antenna 130 can also be other types of antennas, which will not be given one by one here.

[0036] Specifically, if Figure 3 As shown, the main antenna 130 is located on the front side of the circuit board 120, and the parasitic antenna 140 is located on the front side of the main antenna 130. Figure 4 As shown, when the human body 200 wears the smart glasses 100, the electromagnetic radiation of the antenna of the smart glasses 100 is directed toward the front of the human body 200, wherein, Figure 4 The arrows in the figure represent the electromagnetic radiation direction of the antenna.

[0037] Of course, the main antenna 130 can also be located on the rear side of the circuit board 120, and the parasitic antenna 140 can be located on the rear side of the main antenna 130. When the person 200 wears the smart glasses 100, the electromagnetic radiation of the antenna of the smart glasses 100 is directed toward the rear of the person 200. Alternatively, the main antenna 130 can also be located on the upper side of the circuit board 120, and the parasitic antenna 140 can be located on the upper side of the main antenna 130. When the person 200 wears the smart glasses 100, the electromagnetic radiation of the antenna of the smart glasses 100 is directed toward the upper side of the person 200. Alternatively, the main antenna 130 can also be located on the lower side of the circuit board 120, and the parasitic antenna 140 can be located on the lower side of the main antenna 130. When the person 200 wears the smart glasses 100, the electromagnetic radiation of the antenna of the smart glasses 100 is directed toward the lower side of the person 200.

[0038] The circuit board 120 may be a rectangular structure, so that the circuit board 120 has straighter sides, which is more conducive to reflecting the radiation of the main antenna 130.

[0039] Furthermore, the frame 110 includes a mounting portion 116 , on which the circuit board 120 , the main antenna 130 and the parasitic antenna 140 are mounted.

[0040] Specifically, the main antenna 130 and the parasitic antenna 140 may form an axisymmetric structure as a whole.

[0041] And, as Figure 5 As shown, the parasitic antenna 140 includes an antenna body 142, and the antenna body 142 and the main antenna 130 are arranged side by side. In addition, the length of the antenna body 142 is less than the length of the main antenna 130, so that the antenna body 142 can act as a director. That is, the parasitic antenna 140 is located on one side of the antenna body 142, and the parasitic antenna 140 acts as a director for the antenna body 142. The circuit board 120 is located on the other side of the antenna body 142, and the circuit board 120 acts as a reflector for the antenna body 142.

[0042] The length of the antenna body 142 is slightly smaller than the length of the side of the circuit board 120 facing the antenna body 142. The orthographic projection of the antenna body 142 onto the main antenna 130 falls on the main antenna 130.

[0043] like Figure 5 As shown, as a possible embodiment, the parasitic antenna 140 also includes: a switching element 160, the antenna body 142 includes a first body 148 and a second body 150, and the switching element 160 is connected between the first body 148 and the second body 150, and is used to control the conduction or disconnection of the first body 148 and the second body 150.

[0044] Specifically, the antenna body 142 of the parasitic antenna 140 includes a first body 148 and a second body 150. The switch element 160 is provided on at least one of the first body 148 and the second body 150. The switch element 160 has an on state and an off state. By changing the state of the switch element 160, the antenna operating mode of the smart glasses 100 can be switched. When the switch element 160 is in the on state, the smart glasses 100 are in the first operating mode, the first body 148 and the second body 150 are conductive, and in this state, the antenna body 142 forms a complete state and can act as a director for the main antenna 130. When the switch element 160 is in the off state, the smart glasses 100 are in the second operating mode, the first body 148 and the second body 150 are disconnected. In this state, the length of the first body 148 or the second body 150 is much smaller than the operating wavelength of the main antenna 130. Therefore, the first body 148 and the second body 150 cannot act as a director, so that the main antenna 130 can have good signal reception capabilities in multiple directions.

[0045] Therefore, the use of the switch element 160 enables the smart glasses 100 to be adapted to different scenarios, thereby achieving a balance between antenna performance and SAR value. For example, when the smart glasses 100 are worn by a person 200, the switch element 160 can be controlled to conduct, guiding the antenna's radiation direction, increasing the antenna's gain, and reducing the SAR value. However, when the smart glasses 100 are not worn by a person 200, the switch element 160 can be disconnected due to the distance between the smart glasses 100 and the person 200. This stops guiding the antenna's radiation direction, reduces the antenna's gain, and improves the antenna's ability to receive signals in different directions.

[0046] like Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 9 As shown, as a possible implementation, the length of the first body 148 is equal to the length of the second body 150 .

[0047] Specifically, the length of the first body 148 is equal to the length of the second body 150, and after the switch element 160 is disconnected, the length of the first body 148 and the length of the second body 150 are both much smaller than the main antenna 130, and thus when the smart glasses 100 are in the second working mode, the antenna's ability to receive signals in different directions can be improved.

[0048] like Figure 9 As shown, as a possible implementation, there are multiple antenna bodies 142 , and the multiple antenna bodies 142 are spaced apart from each other in a direction close to the main antenna 130 to a direction away from the main antenna 130 .

[0049] Specifically, multiple antenna bodies 142 are arranged at intervals on one side of the main antenna 130, and the multiple antenna bodies 142 are arranged side by side, thereby improving the guiding effect of the radiation of the main antenna 130, wherein the lengths of the multiple antenna bodies 142 gradually decrease from close to the main antenna 130 to away from the main antenna 130. Figure 3 As shown, the parasitic antenna 140 may include two antenna bodies 142, namely a first antenna body 144 and a second antenna body 146. The first antenna body 144 is close to the main antenna 130, and the second antenna body 146 is far away from the main antenna 130. The length of the second antenna body 146 is shorter than that of the first antenna body 144.

[0050] Each of the multiple antenna bodies 142 may include a first body 148 and a second body 150, and multiple switch elements 160 may be provided, connected between different groups of first bodies 148 and second bodies 150. When all of the switch elements 160 are in an on state, the smart glasses 100 are in a first operating mode, with all of the first and second bodies 148, 150 conducting. In this state, the multiple antenna bodies 142 are intact and can act as directors for the main antenna 130. When all of the switch elements 160 are in an off state, the smart glasses 100 are in a second operating mode, with all of the first and second bodies 148, 150 disconnected. In this state, the lengths of the multiple first and second bodies 148, 150 are significantly shorter than the operating wavelength of the main antenna 130. Therefore, the multiple first and second bodies 148, 150 cannot act as directors, allowing the main antenna 130 to have good signal reception capabilities in multiple directions.

[0051] like Figure 6 and Figure 7 As shown, as a possible implementation, the smart glasses 100 further include: a detection component 170, which is electrically connected to the switch element 160 and is provided on the frame 110, for detecting whether the smart glasses 100 are worn. Based on the situation that the smart glasses 100 are worn, the switch element 160 connects the first body 148 and the second body 150; based on the situation that the smart glasses 100 are not worn, the switch element 160 disconnects the first body 148 and the second body 150.

[0052] Specifically, the smart glasses 100 also include a detection component 170, which is electrically connected to the switch element 160. Specifically, the detection component 170 can be directly connected to the switch element 160, or the detection component 170 can be electrically connected to the switch element 160 through the circuit board 120. The detection component 170 is used to detect whether the smart glasses 100 are worn, wherein the detection component 170 includes an infrared sensor or a magnetic sensor, etc., to detect whether the smart glasses 100 are worn.

[0053] When the detection component 170 detects that the smart glasses 100 are being worn, the switch element 160 is in the on state, turning on the first body 148 and the second body 150, guiding the radiation direction of the antenna, increasing the gain of the antenna, and reducing the SAR value. When the detection component 170 detects that the smart glasses 100 are being worn, the switch element 160 is in the off state, and then the first body 148 and the second body 150 can be disconnected, and the radiation direction of the antenna is not guided, the gain of the antenna is reduced, and the antenna's signal receiving ability in different directions is improved.

[0054] The detection component 170 is then used to enhance the intelligence of the smart glasses 100 and automatically switch the working mode of the antenna of the smart glasses 100.

[0055] The detection component 170 may be integrated on the circuit board 120 or may be separated from the circuit board 120 .

[0056] like Figure 9 As shown, as a possible implementation, there are multiple main antennas 130, and the multiple main antennas 130 are respectively arranged on different sides of the circuit board 120. There are multiple parasitic antennas 140, and the parasitic antennas 140 and the main antennas 130 are arranged in a one-to-one correspondence.

[0057] Specifically, there are multiple main antennas 130 and parasitic antennas 140, with one main antenna 130 corresponding to one parasitic antenna 140. A group of main antennas 130 and parasitic antennas 140 can be set on one side of the circuit board 120, and multiple groups of main antennas 130 and parasitic antennas 140 can be set on different sides of the circuit board 120, so that the radiation of each group of main antennas 130 and parasitic antennas 140 is different, thereby improving the signal receiving capability of the smart glasses 100 in different directions.

[0058] Specifically, if Figure 9 As shown, the main antenna 130 has three components, namely a first main antenna 132, a second main antenna 134, and a third main antenna 136. The parasitic antenna 140 has three components, namely a first parasitic antenna 152, a second parasitic antenna 154, and a third parasitic antenna 156. The first main antenna 132 is located on the upper side of the circuit board 120, the first parasitic antenna 152 is located above the first main antenna 132, the second main antenna 134 is located in front of the circuit board 120, the second parasitic antenna 154 is located in front of the second main antenna 134, the third main antenna 136 is located on the lower side of the circuit board 120, and the third parasitic antenna 156 is located below the third main antenna 136. Furthermore, different main antennas 130 can be activated according to different application scenarios to achieve different signal gain directions, thereby reducing power consumption while improving signal reception capabilities.

[0059] like Figure 10 As shown, when the human body 200 wears the smart glasses 100, the electromagnetic radiation of the first main antenna 132 of the smart glasses 100 is directed toward the upper part of the human body 200, the electromagnetic radiation of the second main antenna 134 is directed toward the front of the human body 200, and the electromagnetic radiation of the third main antenna 136 is directed toward the lower part of the human body 200. Figure 10 The arrows in the figure represent the electromagnetic radiation direction of the antenna.

[0060] like Figure 6 and Figure 7As shown, as a possible implementation, the smart glasses 100 further include: a communication component 180 , which is provided on the frame 110 and electrically connected to the circuit board 120 for interactive communication with the electronic device, and a main antenna 130 is provided below the circuit board 120 .

[0061] Specifically, the smart glasses 100 also include a communication component 180 , which is disposed on the frame 110 and connected to the circuit board 120 . The communication component 180 may be integrated on the circuit board 120 or may be separately disposed from the circuit board 120 .

[0062] In addition, the main antenna 130 is located below the circuit board 120. It can be understood that when the human body 200 is standing or sitting upright and wearing the smart glasses 100, the parasitic antenna 140 guides the radiation of the main antenna 130 downward, thereby facilitating interactive communication between the communication component 180 and the electronic device through the antenna.

[0063] Since the lightness of the smart glasses 100 limits its battery capacity, the communication of the smart glasses 100 can be achieved by interacting with other electronic devices, thereby reducing the communication time between the smart glasses 100 and the base station, thereby reducing the power consumption of the smart glasses 100 and improving the battery life of the smart glasses 100.

[0064] The electronic device can be a mobile phone or tablet computer. When the person 200 carries the electronic device, the smart glasses 100 can communicate with the electronic device, reducing power consumption. Specifically, when the person 200 wears the smart glasses 100 and carries the electronic device, the electronic device is typically located below the smart glasses 100. Therefore, the antenna of the smart glasses 100 radiates downward, facilitating interaction between the electronic device and the smart glasses 100.

[0065] In addition, the smart glasses 100 can have multiple main antennas 130 and multiple parasitic antennas 140, with one group of the multiple main antennas 130 and the multiple parasitic antennas 140 located below the circuit board 120, and the other groups located in other directions of the circuit board 120. This can not only promote the interaction between the smart glasses 100 and electronic devices, but also enhance the signal receiving capability of the smart glasses 100 in other directions.

[0066] Specifically, if Figure 7 As shown, the main antenna 130 is located on the lower side of the circuit board 120, and the parasitic antenna 140 is located on the lower side of the main antenna 130. Figure 8 As shown, when the human body 200 wears the smart glasses 100, the electromagnetic radiation of the antenna of the smart glasses 100 is directed toward the bottom of the human body 200, wherein, Figure 8 The arrows in the figure represent the electromagnetic radiation direction of the antenna.

[0067] As a possible implementation, the circuit board 120 and the main antenna 130 are separate structures; or the circuit board 120 and the main antenna 130 are integrated structures.

[0068] Specifically, the circuit board 120 and the main antenna 130 may adopt a split structure.

[0069] Alternatively, the circuit board 120 and the main antenna 130 may be integrated. The frequency of the main antenna 130 may be greater than or equal to 10 GHz, thereby facilitating integration of the circuit board 120 and the main antenna 130 , reducing costs, improving antenna gain, and lowering the antenna's SAR value.

[0070] like Figure 1 and Figure 2 As shown, as a possible embodiment, the frame 110 includes: a frame 112; temples 114, which are arranged on the frame 112, and the circuit board 120, the main antenna 130 and the parasitic antenna 140 are arranged on the temples 114, and the circuit board 120, the main antenna 130 and the parasitic antenna 140 are located in the same layer in the thickness direction of the temples 114.

[0071] Specifically, the frame 110 includes a frame 112 and temples 114. The frame 112 is used to mount the lenses 190. There are two temples 114 mounted on either side of the frame 112. The connection between the temples 114 and the frame 112 can be a hinged or integrated structure. The circuit board 120, the main antenna 130, and the parasitic antenna 140 are disposed on the temples 114 and located near the frame 112. When the smart glasses 100 are worn by a person 200, the circuit board 120, the main antenna 130, and the parasitic antenna 140 are further away from the person 200, thereby further reducing the impact of the antenna's electromagnetic radiation on the person 200. The circuit board 120, the main antenna 130, and the parasitic antenna 140 are disposed on at least one of the two temples 114.

[0072] Among them, the thickness direction of the temple 114 can be understood as the direction from the human body 200 to the outside of the human body 200 when the human body 200 wears the smart glasses 100, that is, the direction from the side of the temple 114 facing the human body 200 to the side away from the human body 200, as well as the direction from one temple 114 to another temple 114, and the direction from one end to the other end of the frame 112.

[0073] Furthermore, the temple 114 includes a mounting portion 116, and the circuit board 120, the main antenna 130 and the parasitic antenna 140 are mounted on the mounting portion 116. The mounting portion 116 can be provided on one temple 114, or both temples 114 can be provided with mounting portions 116.

[0074] like Figure 2 As shown, as a possible implementation, the circuit board 120 extends along the length direction of the temple 114 .

[0075] Specifically, the circuit board 120 extends along the length direction of the temple 114, and the length direction of the temple 114 refers to the end connected to the temple 114 and the frame 112 to the end of the temple 114 away from the frame 112, so that the circuit board 120 and the temple 114 are parallel, which facilitates the layout of the circuit board 120 and the setting of the main antenna 130 and the parasitic antenna 140.

[0076] That is, the thickness direction of the circuit board 120 is the same as the thickness direction of the temple 114 , and the circuit board 120 and the temple 114 are arranged in parallel.
