Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.​​​

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0026] The following will be described in detail in combination with the accompanying drawings Figures 1-11 The intelligent glasses provided by the embodiments of the present application are described in detail through specific embodiments and application scenarios.

[0027] The embodiments of the present application specifically disclose an intelligent glasses, which specifically can include a glasses frame 2 and at least two antennas 1, wherein the at least two antennas 1 can be arranged on the glasses frame 2; the two adjacent antennas 1 can be arranged orthogonally.

[0028] In the embodiments of the present application, the antenna assembly of the intelligent glasses includes at least two antennas 1, and the two adjacent antennas 1 are arranged orthogonally, so that the two adjacent antennas 1 can be complementary, and the radiation direction of the antenna assembly can be covered omnidirectionally without dead angle. In this way, the user can wear the intelligent glasses in different scenarios such as looking up, looking down, diving or turning sideways, and the antenna assembly can ensure stable signal transmission and reception, which can improve the reliability of the interaction between the intelligent glasses and the user and improve the user experience.

[0029] The intelligent glasses described in the embodiments of the present application can also be called intelligent glasses, which can have an independent operating system like a smart phone. The intelligent glasses are a general term for wearable glasses devices that can realize various functions through software installation.

[0030] Specifically, the intelligent glasses can interact with the user, for example: voice control, gesture recognition, eye tracking, etc.

[0031] Specifically, the intelligent glasses can include a glasses frame 2, which can be the body structure of the intelligent glasses. The glasses frame 2 specifically can include a frame 21 and a temple 22, and the temple 22 can be fixedly connected or movably connected with the frame 21; the frame 21 can also be used to fix and install a lens.

[0032] Specifically, the smart glasses can further include an antenna assembly, which can include at least two antennas 1, which can be used for transmitting and receiving signals to realize the interaction between the smart glasses and the user. The antennas 1 can be monopole antennas, dipole antennas, or loop antennas, etc., which can be specifically set according to actual needs.

[0033] Specifically, the antennas 1 can be adjusted in position according to the shape of the glasses frame 2 to realize the layout of the antennas 1 according to the shape of the glasses frame 2, which can be adapted to smart glasses of various shapes.

[0034] As shown in Figure 8 , one form of arrangement of the antennas 1 is shown; as shown in Figure 10 , another form of arrangement of the antennas 1 is shown; as shown in Figure 11 , another form of arrangement of the antennas 1 is shown, and other cases can be set according to actual needs, which are not specifically limited in the embodiments of the application.

[0035] As shown in Figure 1 , Figure 3 and Figure 5 , various antennas 1 are adapted to the glasses frame 2 for arrangement, and other cases can be set by reference, which are not specifically limited in the embodiments of the application.

[0036] Specifically, the antennas 1 can be flexible structures, which facilitate the fixation of the antennas 1 on the glasses frame 2. For example, the antennas 1 can be metal steel sheets, or FPC (Flexible Printed Circuit board), or PCB (Printed Circuit Board), or structures processed by LDS (LDS-Laser Direct Structuring, laser direct structuring technology), or PDS (Premises Distribution System, integrated wiring system with a single wiring system, which integrates the wiring required by all communication devices, including voice, data, image, monitoring, etc.), etc., which can be specifically set according to actual needs, which are not specifically limited in the embodiments of the application.

[0037] Specifically, the antenna assembly can specifically include two, three, four, or more antennas 1, which can be specifically set according to actual needs, which are not specifically limited in the embodiments of the application. Further, the more the number of antennas 1, the more comprehensive the radiation direction of the antenna assembly can cover. The coverage performance of the antenna assembly formed by four antennas 1 can be doubled on the basis of the antenna assembly formed by two antennas 1.

[0038] Specifically, the two adjacent antennas 1 are orthogonally arranged, so that the two adjacent antennas 1 can be complementary to each other. In this way, in the case that the user wears the smart glasses, no matter the user looks up, looks down or dives in different use scenarios, the antenna 1 with stronger signal in the current scenario can be switched to transmit signals, so as to effectively ensure the stability of the interaction between the smart glasses and the user in different use scenarios.

[0039] Further, the at least two antennas 1 are arranged in sequence, and the two adjacent antennas 1 are orthogonally arranged, so that the two adjacent antennas 1 can be complementary to each other, and the radiation direction of the antenna assembly can be fully covered. The radiation direction can be any direction of the space where the antenna 1 is located.

[0040] As shown in Figure 1 , the antenna assembly can include two antennas 1, which can be named as ANT1 and ANT2 respectively. As shown in Figure 2 , the directional diagram of ANT1 and the directional diagram of ANT2 are shown.

[0041] As can be seen from Figure 1 and Figure 2 , the directional diagram of ANT1 and the directional diagram of ANT2 are complementary, so that the radiation direction of the antenna assembly can be fully covered. Moreover, in the direction where the radiation signal of ANT1 is weak, the radiation signal of ANT2 is strong; in the direction where the radiation signal of ANT2 is weak, the radiation signal of ANT1 is strong. In this way, according to the use scenario of the smart glasses, the antenna 1 with stronger signal in the radiation direction corresponding to the current use scenario in the antenna assembly can be switched to transmit signals.

[0042] Specifically, the orthogonally arranged two adjacent antennas 1 include: the two adjacent antennas 1 are completely orthogonal, and the two adjacent antennas 1 are close to orthogonal. When the two adjacent antennas 1 are completely orthogonal, the two adjacent antennas 1 can be perpendicular to each other; when the two adjacent antennas 1 are close to orthogonal, the included angle between the two adjacent antennas 1 can be close to 90 degrees.

[0043] Specifically, the orthogonally arranged two adjacent antennas 1 can reduce the signal interference between the two adjacent antennas 1. The closer the included angle between the two adjacent antennas 1 is to 90 degrees, the better the comprehensive coverage of the radiation direction of the antenna assembly is.

[0044] For example, in the two adjacent antennas 1, one of the antennas 1 has weaker signal in a first direction, and the other antenna 1 has stronger signal in the first direction; one of the antennas 1 has stronger signal in a second direction, and the other antenna 1 has weaker signal in the second direction. In this way, in the case that the signal radiation intensity of one of the antennas 1 is weak, the adjacent antenna 1 can be used to compensate.

[0045] Optionally, the antenna 1 can include a first branch 13 and a second branch 14, the first branch 13 can be used for receiving and transmitting signals of a first frequency band, and the second branch 14 can be used for receiving and transmitting signals of a second frequency band; the arm length of the first branch 13 can be smaller than the arm length of the second branch 14.

[0046] In the embodiment of the present application, the antenna 1 includes a first branch 13 and a second branch 14, the arm length of the first branch 13 is smaller than the arm length of the second branch 14, so that the antenna 1 can receive waves of different frequency bands.

[0047] Specifically, the first branch 13 can be used for receiving and transmitting waves of a WIFI 5.0G frequency band; and the second branch 14 can be used for receiving and transmitting waves of a WIFI 2.4G frequency band.

In order to facilitate the orthogonal arrangement of the two antennas 1, the two antennas 1 can be arranged at opposite positions of the frame 21; or the two antennas 1 can be arranged at positions close to the central axis 211 of the frame 21 and intersect at the central axis 211 of the frame 21; or one antenna 1 can be arranged on the frame 21 and the other antenna 1 can be arranged on the temple 22.
