Description

Technical Field

[0001] This application belongs to the technical field of intelligent terminals, and particularly relates to a pair of intelligent glasses. Background Art

[0002] With the development and progress of mobile communication systems, the styles of intelligent glasses have become more and more diverse. Intelligent glasses can serve as a medium for users to interact with the real world or the virtual world, and include two technologies: Augmented Reality (AR) and Virtual Reality (VR). When implementing the above technologies, intelligent glasses need to incorporate a processor, a display, sensors, and input devices, which makes intelligent glasses generally heavy and the supported frequency bands relatively single. When using intelligent glasses, the usage time is usually long. For the comfort of users, the volume and weight of intelligent glasses need to be strictly controlled during hardware design, which leaves very limited available space for the antenna and affects the radiation performance of the antenna. Summary of the Invention

[0003] An embodiment of this application provides a pair of intelligent glasses, which can solve the problem that the radiation performance of the antenna of existing intelligent glasses is affected due to the small available space of the antenna.

[0004] This application provides a pair of intelligent glasses, including: a frame and temple arms, the frame is connected to the temple arms;

[0005] An antenna unit is provided on the temple arms, the antenna unit includes a first antenna radiator and a first antenna feeding structure, the first antenna radiator is a spiral structure, one end of the first antenna radiator is connected to the first antenna feeding structure, and the other end of the first antenna radiator is connected to the frame;

[0006] Wherein, the intelligent glasses can be switched between a wearing state and a folded state. When the intelligent glasses are in different states, the first antenna radiator undergoes elastic deformation, and the radiation direction of the first antenna radiator relative to the frame remains unchanged.

[0007] In an embodiment of the present application, the smart glasses include a frame and temple arms. The frame is connected to the temple arms, and an antenna unit is provided on the temple arms. The antenna unit includes a first antenna radiator and a first antenna feeding structure. The first antenna radiator is a spiral structure.

At the same time, the unfolding and folding of the smart glasses are used to make the first antenna radiator undergo elastic deformation, so that it changes into different spiral antennas, but the radiation direction of the first antenna radiator relative to the frame remains unchanged, which is beneficial to the continuity of communication and avoids the situation of communication interruption caused by different states. Moreover, the above functions can be realized without adding an electronic switch and the corresponding circuit, which improves the antenna radiation performance while reducing the weight of the antenna.

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data 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, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0026] Next, in conjunction with the attached Figures 1-10 , a smart glasses 100 provided by an embodiment of the present application will be described in detail through specific embodiments and their application scenarios.

[0027] Such as Figure 1As shown in the figure, it is a schematic structural diagram of a smart glasses 100 provided by the present application. As shown in the figure, the smart glasses 100 includes: a frame 110 and temple arms 120. The frame 110 is connected to the temple arms 120, which can be rotatably connected through a rotating shaft 140 or rotatably connected through other mechanical structures. An antenna unit 130 is provided on the temple arms 120. The antenna unit 130 includes a first antenna radiator 131 and a first antenna feeding structure 132. The first antenna radiator 131 is a spiral structure, that is, the antenna is a spiral antenna. One end of the first antenna radiator 131 is connected to the first antenna feeding structure 132, and the other end of the first antenna radiator 131 is connected to the frame 110. Among them, the smart glasses 100 can be switched between a wearing state and a folding state. In the case where the smart glasses 100 are in different states, the first antenna radiator 131 undergoes elastic deformation, and the radiation direction of the first antenna radiator 131 relative to the frame 110 remains unchanged.

[0028] That is to say, the antenna unit 130 is a spiral antenna. After the smart glasses 100 are switched from the wearing state to the folding state, the first antenna radiator 131 undergoes elastic deformation, that is, both the spiral diameter and the pitch of the first antenna radiator 131 will change, but the radiation direction of the first antenna radiator 131 relative to the frame 110 remains unchanged. Among them, the spiral antenna can be formed by using a metal material with a certain strength and elasticity to play a role in supporting the temple arms 120. The forms of the antenna include, but are not limited to, flexible printed circuit (FPC), metal wires and other materials with strong plasticity capable of forming an antenna. The selection space is large, and the spiral structure can be of various shapes, not limited to circular or elliptical, which can reduce the processing cost of materials.

[0029] Specifically, the other end of the first antenna radiator 131 is connected to the frame 110. When the smart glasses 100 are switched between the wearing state and the folding state, due to the movement of the temple arms, since the other end of the first antenna radiator 131 is fixed to the frame 110, the movement of the temple arms 120 can drive the first antenna radiator 131 to stretch or contract, thereby changing the spiral diameter and pitch.

[0030] It is worth noting that, as Figure 2 shown, when the spiral circumference of the spiral antenna is much smaller than the operating wavelength, that is, when D / λ < 0.18, its performance is similar to that of a monopole antenna, and it is normal radiation, that is, the maximum radiation direction is perpendicular to the winding direction of the spiral; as Figure 3 shown, when the spiral circumference and the operating wavelength are comparable, that is, when D / λ = 0.25 - 0.46, its performance is axial, that is, a circularly polarized antenna with radiation in the winding direction; as Figure 4As shown, when the helix circumference is much larger than the operating wavelength, i.e., D / λ > 0.5, its radiation direction is inclined to the axial direction. Here, D is the helix diameter of the helical antenna, and λ is the operating wavelength of the helical antenna.

[0031] Among them, the temple 120 can be used as a carrier structure of the antenna unit 130. For example, by drilling holes inside the temple 120 and arranging the antenna in the holes, the appearance of the smart glasses 100 can be unaffected. The first antenna radiator 131 of the antenna unit 130 adopts a helical structure. Since its wiring is not in one direction but along the direction of the temple 120, the force in a certain direction is weaker and it is not easily damaged.

[0032] In the embodiment of the present application, the smart glasses 100 include a frame 110 and temples 120. The frame 110 is connected to the temples 120. An antenna unit 130 is provided on the temples 120. The antenna unit 130 includes a first antenna radiator 131 and a first antenna feeding structure 132. The first antenna radiator 131 is a helical structure. One end of the first antenna radiator 131 is connected to the first antenna feeding structure 132, and the other end of the first antenna radiator 131 is connected to the frame 110. The smart glasses 100 can be switched between a wearing state and a folded state. In the case where the smart glasses 100 are in different states, the first antenna radiator 131 undergoes elastic deformation, and the radiation direction of the first antenna radiator 131 relative to the frame 110 remains unchanged. The antenna unit 130 in the embodiment of the present application adopts a helical structure, which can make the size of the antenna smaller, reduce the volume occupied by the antenna unit 130 in the smart glasses 100, and at the same time utilize the unfolding and folding of the smart glasses 100 to change the helix diameter and pitch of the first antenna radiator 131, making it change into different helical antennas, but keeping its radiation direction relative to the frame 110 unchanged, which is beneficial to the continuity of communication, avoids the situation of communication interruption due to different states, and does not require adding an electronic switch and the corresponding circuit to achieve the above functions. While reducing the weight of the antenna, the radiation performance of the antenna is improved.

[0033] As Figure 5 shown, optionally, the other end of the first antenna radiator 131 can be connected to the rotating shaft 140 between the temple 120 and the frame 110. Through the rotation of the rotating shaft 140, the first antenna radiator 131 is driven to stretch or contract, thereby changing the helix diameter and pitch.

[0034] The embodiment of the present application utilizes the original structure of the smart glasses 100 to design the antenna, making the smart glasses 100 closer to ordinary glasses and meeting the user's usage habits.

[0035] In a possible implementation of the present application, the smart glasses 100 may further include: a circuit board disposed within the first dielectric tube 133, and the first dielectric tube 133 is disposed within the temple 120.

[0036] Wherein, the circuit board may be a printed circuit board (PCB), which can provide better support for the temple 120.

[0037] In the embodiment of the present application, the first dielectric tube 133 is wrapped around the outside of the circuit board, further providing support for the temple 120, making the temple 120 more resistant to interference.

[0038] Such as Figure 6 As shown, in a possible implementation of the present application, a first hole 134 is provided on the side wall of the first dielectric tube 133, the first antenna radiator 131 is spirally wound around the first dielectric tube 133, the first antenna feeding structure 132 is disposed on the circuit board, and one end of the first antenna radiator 131 is connected to the first antenna feeding structure 132 through the first hole 134.

[0039] Wherein, when the smart glasses 100 are in the worn state, the spiral diameter of the first antenna radiator 131 is the first diameter, and the radiation direction of the first antenna radiator 131 is along the direction of the temple 120. When the smart glasses 100 are in the folded state, the first antenna radiator 131 is in a stretched state, the spiral diameter of the first antenna radiator 131 is the second diameter, and the radiation direction of the first antenna radiator 131 is perpendicular to the direction of the temple 120, wherein the first diameter is greater than the second diameter.

[0040] Since the first antenna radiator 131 is wound around the first dielectric tube 133, when the smart glasses are in the worn state, the spiral diameter of the first antenna radiator 131 is the first diameter, and the radiation direction of the first antenna radiator 131 is along the direction of the temple 120, that is, the radiation direction of the first antenna radiator 131 is towards the front of the smart glasses 100, which can avoid human body absorption and improve the radiation performance. When the smart glasses 100 are in the folded state, the first antenna radiator 131 is stretched and in a stretched state, the spiral diameter of the first antenna radiator 131 becomes smaller and becomes the second diameter. Since the spiral diameter of the first antenna radiator 131 becomes smaller, its radiation direction will also change to a direction perpendicular to the original radiation direction, that is, the radiation direction of the first antenna radiator 131 is perpendicular to the direction of the temple 120, that is, the radiation direction of the first antenna radiator 131 is still towards the front of the smart glasses 100, which can reduce the influence of the tabletop, etc. on the antenna performance, and at the same time is beneficial to the continuity of communication, avoiding the situation of communication interruption due to different states.

[0041] That is to say, the first antenna radiator 131 can be spirally wound around the first dielectric tube 133. The first antenna radiator 131 can be fed by a coaxial cable. One end of the first antenna radiator 131 can pass through the first hole 134 and be connected to the first feeding structure arranged on the circuit board, so that the first feeding structure feeds the spiral antenna.

[0042] It is worth noting that the first antenna feeding structure 132 can include a feeding point and a grounding point. The feeding point is used to feed the spiral antenna, and the grounding point is used for the spiral antenna to be grounded. That is to say, both the feeding point and the grounding point of the antenna can be arranged on the circuit board to reduce the volume occupied by the antenna unit 130 in the smart glasses 100.

[0043] In a specific embodiment of the present application, as Figure 7 shown, it is a schematic diagram when the temple 120 is unfolded in the normal state. At this time, the diameter of the antenna is larger, and the radiation direction of the antenna is along the X-axis. When the temple 120 is folded, the antenna is stretched, and the diameter of the spiral becomes smaller, as Figure 8 shown. At this time, the radiation pattern of the antenna changes from the axial mode parallel to the spiral axis to the mode perpendicular to the axis, and the main radiation direction of the antenna still along the X-axis. This consistent radiation direction in the wearing state and the folding state is beneficial to the continuity of communication and avoids the situation of communication interruption due to different states.

[0044] This embodiment is compatible with the wearing state and the folding state of the smart glasses 100, ensuring that the antenna can have good performance in both states.

[0045] As Figure 9 shown, in a possible embodiment of the present application, the antenna unit 130 further includes a second antenna radiator 135 and a second antenna feeding structure 136. The second antenna radiator 135 is a spiral structure, and the second antenna radiator 135 is connected to the second antenna feeding structure 136.

[0046] That is to say, in addition to the first antenna composed of the first antenna radiator 131 and the first antenna feeding structure 132, the antenna unit 130 can also include other antenna structures to increase the radiation direction of the antenna unit 130 and increase the operating frequency band of the antenna unit 130. Among them, the antenna formed by the second antenna radiator 135 can also be a spiral antenna. Specifically, it has been described in detail in the above embodiment and will not be elaborated in the present application.

[0047] Optionally, the smart glasses 100 further include a second dielectric tube 137. The second dielectric tube 137 is sleeved on the first dielectric tube 133, and the second antenna radiator 135 is spirally wound around the second dielectric tube 137. The two sleeved dielectric tubes can further provide support for the temple 120, making the temple 120 more resistant to interference.

[0048] Optionally, a second hole 138 is provided on the side wall of the second dielectric tube 137, the second antenna feeding structure 136 is disposed on the circuit board, and the second antenna radiator 135 is connected to the second antenna feeding structure 136 through the second hole 138.

[0049] Wherein, the helix diameters and pitches of the first antenna radiator 131 and the second antenna radiator 135 are different.

[0050] In the embodiment of the present application, a second dielectric tube 137 is added outside the first dielectric tube 133. The first antenna radiator 131 on the first dielectric tube 133 forms a stretchable antenna structure, and the second antenna radiator 135 forms a non-stretchable antenna structure. Since the helix diameters and pitches of the two antenna radiators are different, the operating frequency bands of the antennas formed by the two antenna radiators are also different, which can increase the operating frequency band of the antenna unit 130. Moreover, by controlling the deformation or helix diameter of the two antenna radiators, the two antennas formed by the two antenna radiators can achieve omnidirectional radiation, improving the performance of the antenna unit 130.

[0051] In a specific embodiment of the present application, the two spiral antennas formed by the first antenna radiator 131 and the second antenna radiator 135 can be regarded as conformal antennas. When the smart glasses 100 are in the wearing state, the radiation pattern of the inner spiral antenna, that is, the antenna formed by the first antenna radiator 131, presents a pencil-shaped beam along the axis, and the maximum radiation direction points forward. The radiation pattern of the outer spiral antenna, that is, the antenna formed by the second antenna radiator 135, is perpendicular to the spiral axis. At this time, 360° omnidirectional radiation can be achieved. When the smart glasses 100 are in the folded state, the helix diameter of the inner spiral is stretched by the connected rotating shaft 140 and deformed. At this time, the maximum radiation direction of the inner spiral antenna points forward. Since the outer spiral antenna is not deformed, the radiation pattern of the outer spiral antenna is perpendicular to the spiral axis, so 360° omnidirectional radiation is achieved.

[0052] As Figure 6 shown, in a possible embodiment of the present application, the antenna unit 130 further includes an antenna ground plane 139. The antenna ground plane 139 is disposed on the side of the first antenna radiator 131 away from the lens frame 110, and the antenna ground plane 139 is connected to the first antenna radiator 131.

[0053] That is to say, the antenna ground plane 139 of the antenna can be disposed on the circuit board or separately provided to further improve the performance of the antenna. Moreover, by disposing the antenna ground plane 139 on the side away from the lens frame 110, the space at this position is small and not suitable for placing other devices, so that the antenna ground plane 139 does not occupy extra space. Specifically, the antenna ground plane 139 can be placed on the central axis of the first dielectric tube 133.

[0054] As shown Figure 10 Optionally, the antenna floor 139 is two metal rings spaced apart from each other.

[0055] The distance between the two metal rings can be λ / 3 to λ / 2, where λ is the operating wavelength of the antenna element 130. Specifically, the two metal rings can be fixed by plastic casting on the side of the first antenna radiator 131 facing away from the frame 110.

[0056] In other embodiments, the antenna floor 139 can also be other shapes, such as a cup-shaped metal plate, a rectangular metal plate, etc., which are specifically determined according to actual applications.

[0057] As shown Figure 7 In a possible implementation manner of the present application, the temple 120 can include a first temple 121 and a second temple 122, and the antenna element 130 is provided in both the first temple and the second temple.

[0058] That is to say, the antenna element 130 can be provided in both the two temples 120 to further increase the operating frequency of the antenna element 130, so that the antenna element 130 can operate in more frequency bands to meet various needs of users.

[0059] It should be noted that in this article, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without more limitations, the element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved. For example, the described methods can be performed in an order different from that described, and various steps can also be added, omitted, or combined. In addition, the features described with reference to certain examples can be combined in other examples.

[0060] Through the description of the above embodiments, those skilled in the art can clearly understand that the above-described example methods can be implemented by means of software plus a necessary general hardware platform. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation. Based on such an understanding, the technical solution of the present application, in essence, or the part that contributes to the prior art, can be embodied in the form of a computer software product. The computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions for causing a terminal (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in various embodiments of the present application.

[0061] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them fall within the protection scope of the present application.
