[0018] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0022] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0024] Figure 1 This is a schematic diagram of the structure of an antenna system according to an embodiment of the present disclosure.

[0025] like Figure 1 As shown, the antenna system includes a battery 101 and a radio frequency system 102. The casing of the battery 101 is a conductor. The radio frequency system 102 is connected to the casing of the battery 101 so that the casing of the battery 101 serves as a radiator for the radio frequency system 102.

[0026] Therefore, by reusing batteries to act as antenna radiators, there is no need to set up separate antennas, reducing antenna components and thus saving the limited internal assembly space of AI glasses and simplifying the overall structure.

[0027] In some embodiments, the radio frequency system 102 is electrically connected to the casing of the battery 101 via a designated terminal of the battery 101.

[0028] In some embodiments, the designated terminal corresponds to the positive or negative electrode of the battery 101.

[0029] For example, the radio frequency system 102 is electrically connected to the casing of the battery 101 via the positive electrode of the battery 101.

[0030] For example, the radio frequency system 102 is electrically connected to the casing of the battery 101 via the negative electrode of the battery 101.

[0031] Therefore, the radio frequency system 102 can reuse the electrode terminals of the battery 101 without adding additional radio frequency-specific connection points to the battery 101, thereby simplifying the overall structure.

[0032] Figure 2 This is a schematic diagram of the structure of an antenna system according to another embodiment of the present disclosure.

[0033] like Figure 2 As shown, the antenna system also includes an antenna matching network 103, the first terminal of which is electrically connected to the radio frequency system 102, and the second terminal of which is electrically connected to a designated terminal of the battery 101.

[0034] For example, the first terminal of the antenna matching network 103 is electrically connected to the radio frequency system 102, and the second terminal of the antenna matching network 103 is electrically connected to the positive electrode of the battery 101.

[0035] For example, the first terminal of the antenna matching network 103 is electrically connected to the radio frequency system 102, and the second terminal of the antenna matching network 103 is electrically connected to the negative electrode of the battery 101.

[0036] This reduces the reflection of radio frequency signals and improves the transmission efficiency of the radio frequency system to the radiator in the battery casing.

[0037] like Figure 2 As shown, the antenna system also includes a first DC blocking circuit 104, the first terminal of which is electrically connected to the antenna matching network 103, and the second terminal of which is electrically connected to a designated terminal of the battery 101.

[0038] For example, the first terminal of the first DC blocking circuit 104 is electrically connected to the antenna matching network 103, and the second terminal of the first DC blocking circuit 104 is electrically connected to the positive electrode of the battery 101.

[0039] For example, the first terminal of the first DC blocking circuit 104 is electrically connected to the antenna matching network 103, and the second terminal of the first DC blocking circuit 104 is electrically connected to the negative electrode of the battery 101.

[0040] It should be noted that the first DC blocking circuit 104 presents high impedance to DC signals, which can block the transmission of DC voltage from the battery 101 side to the antenna matching network 103 and the radio frequency system 102, protecting the radio frequency system 102 from the influence of the DC potential of the battery 101. The first DC blocking circuit 104 presents low impedance to radio frequency signals in the target operating frequency band, allowing the radio frequency signals to be fed into the battery 101 casing, thereby ensuring the antenna's radiation function.

[0041] Figure 3 This is a schematic diagram of the structure of smart glasses according to an embodiment of the present disclosure.

[0042] like Figure 3 As shown, the smart glasses include a power system 301 and an antenna system 302, wherein the antenna system 302 is the antenna system described in any of the above embodiments.

[0043] For example, such as Figure 3As shown, the antenna system 302 includes a battery 101 and a radio frequency system 102. The radio frequency system 102 is electrically connected to the casing of the battery 101 via designated terminals of the battery 101.

[0044] The power system 301 is electrically connected to the battery in the antenna system 302 so that the power system 301 is powered by the battery.

[0045] Figure 4 This is a schematic diagram of the structure of smart glasses according to another embodiment of the present disclosure.

[0046] like Figure 4 As shown, the first terminal of the power system 301 is electrically connected to the first terminal of the battery 101, and the second terminal of the power system 301 is electrically connected to the second terminal of the battery 101. The first terminal and the second terminal of the battery 101 correspond to battery electrodes of different polarities.

[0047] The smart glasses also include a first high-frequency impedance circuit 401 and a second high-frequency impedance circuit 402. The first high-frequency impedance circuit 401 is disposed on the line between the first terminal of the power system 301 and the first terminal of the battery 101. The second high-frequency impedance circuit 402 is disposed on the line between the second terminal of the power system 301 and the second terminal of the battery 101.

[0048] It should be noted that the first high-frequency impedance circuit 401 and the second high-frequency impedance circuit 402 present high impedance to the radio frequency signals of the antenna operating frequency band, which can suppress the leakage of radio frequency signals from the battery casing to the power system, prevent radio frequency energy from being absorbed by the power system, and thus reduce the power loss of the antenna.

[0049] In some embodiments, the smart glasses further include a second DC blocking circuit 403. The first terminal of the second DC blocking circuit 403 is electrically connected to a first designated terminal of the battery 101, and the second terminal of the second DC blocking circuit 403 is electrically connected to a ground network. The second designated terminal of the battery 101 is electrically connected to a radio frequency system 102 in the antenna system. The first designated terminal corresponds to one of the positive and negative electrodes of the battery 101, and the second designated terminal corresponds to the other of the positive and negative electrodes of the battery 101.

[0050] For example, such as Figure 4 As shown, the first designated terminal 1011 of battery 101 is the negative electrode, and the second designated terminal 1012 of battery 101 is the positive electrode. The first terminal of the second DC blocking circuit 403 is electrically connected to the first designated terminal 1011 of battery 101, the second terminal of the second DC blocking circuit 403 is electrically connected to the grounding network, and the second designated terminal 1012 of battery 101 is electrically connected to the radio frequency system 102 in the antenna system.

[0051] For example, such as Figure 5As shown, the first designated terminal 1011 of battery 101 is the positive electrode, and the second designated terminal 1012 of battery 101 is the negative electrode. The first terminal of the second DC blocking circuit 403 is electrically connected to the first designated terminal 1011 of battery 101, the second terminal of the second DC blocking circuit 403 is electrically connected to the grounding network, and the second designated terminal 1012 of battery 101 is electrically connected to the radio frequency system 102 in the antenna system.

[0052] This prevents parasitic parameters of the grounding network from coupling into the radio frequency system, thus reducing stray parasitic loads.

[0053] In some embodiments, the smart glasses further include a third DC blocking circuit 404, the first terminal of which is electrically connected to a third designated terminal of the battery 101, and the second terminal of which is electrically connected to a grounding network. The third designated terminal of the battery 101 corresponds to either the positive or negative electrode of the battery 101.

[0054] For example, such as Figure 6 As shown, the third designated terminal 1013 of battery 101 is the positive electrode, the first terminal of the third DC blocking circuit 404 is electrically connected to the third designated terminal 1013 of battery 101, and the second terminal of the third DC blocking circuit 404 is electrically connected to the grounding network. The first designated terminal 1011 of battery 101 is the negative electrode, and the second designated terminal 1012 of battery 101 is the positive electrode.

[0055] It should be noted here that... Figure 6 As an example only, there are also cases where the first designated terminal 1011 of the battery 101 is the positive electrode and the second designated terminal 1012 of the battery 101 is the negative electrode.

[0056] For example, such as Figure 7 As shown, the third designated terminal 1013 of battery 101 is the negative electrode, the first terminal of the third DC blocking circuit 404 is electrically connected to the third designated terminal 1013 of battery 101, and the second terminal of the third DC blocking circuit 404 is electrically connected to the grounding network. The first designated terminal 1011 of battery 101 is the positive electrode, and the second designated terminal 1012 of battery 101 is the negative electrode.

[0057] It should be noted here that... Figure 7 For example only, there are also cases where the first designated terminal 1011 of the battery 101 is the negative electrode and the second designated terminal 1012 of the battery 101 is the positive electrode.

[0058] Therefore, it is possible to adjust the magnitude of the radio frequency current in different areas of the battery casing, so that the current magnitude is different on the side closer to the head and the side farther away from the head, thereby achieving the control of the radio frequency current distribution.

[0059] In some embodiments, the first terminal of the second DC blocking circuit 403 is electrically connected to a first designated terminal of the battery 101, and the second terminal of the second DC blocking circuit 403 is electrically connected to a grounding network. The first designated terminal corresponds to one of the positive and negative electrodes of the battery.

[0060] The first terminal of the third DC blocking circuit 404 is electrically connected to the second designated terminal of the battery 101, and the second terminal of the third DC blocking circuit 404 is electrically connected to the grounding network. The second designated terminal corresponds to the other electrode among the positive and negative electrodes of the battery 101.

[0061] The third designated terminal of the battery 101 is electrically connected to the radio frequency system 102 in the antenna system, and the third designated terminal of the battery 101 corresponds to the positive electrode or negative electrode of the battery 101.

[0062] For example, such as Figure 8 As shown, the first designated terminal 1011 of the battery 101 is the negative electrode, the second designated terminal 1012 is the positive electrode, the third designated terminal 1013 is the positive electrode, the first terminal of the second DC blocking circuit 403 is electrically connected to the first designated terminal 1011 of the battery 101, and the second terminal of the second DC blocking circuit 403 is electrically connected to the grounding network.

[0063] The first terminal of the third DC blocking circuit 404 is electrically connected to the second designated terminal 1012 of the battery 101, and the second terminal of the third DC blocking circuit 404 is electrically connected to the ground network. The third designated terminal 1013 of the battery 101 is electrically connected to the radio frequency system 102 in the antenna system.

[0064] It should be noted here that... Figure 8 As an example only, there are also cases where the first designated terminal 1011 of the battery 101 is the positive electrode and the second designated terminal 1012 of the battery 101 is the negative electrode.

[0065] For example, such as Figure 9 As shown, the first designated terminal 1011 of the battery 101 is the positive electrode, the second designated terminal 1012 is the negative electrode, the third designated terminal 1013 is the negative electrode, the first terminal of the second DC blocking circuit 403 is electrically connected to the first designated terminal 1011 of the battery 101, and the second terminal of the second DC blocking circuit 403 is electrically connected to the grounding network.

[0066] The first terminal of the third DC blocking circuit 404 is electrically connected to the second designated terminal 1012 of the battery 101, and the second terminal of the third DC blocking circuit 404 is electrically connected to the ground network. The third designated terminal 1013 of the battery 101 is electrically connected to the radio frequency system 102 in the antenna system.

[0067] It should be noted here that... Figure 9For example only, there are also cases where the first designated terminal 1011 of the battery 101 is the negative electrode and the second designated terminal 1012 of the battery 101 is the positive electrode.

[0068] Therefore, the conductive properties of the battery's outer conductor can be used to implement an antenna system within the battery system.

[0069] In some embodiments, the smart glasses further include a fourth DC blocking circuit 405, the first terminal of which is electrically connected to a third designated terminal of the battery 101, and the second terminal of which is electrically connected to a grounding network.

[0070] For example, such as Figure 10 As shown, the first designated terminal 1011 of battery 101 is the positive electrode, the second designated terminal 1012 is the negative electrode, and the third designated terminal 1013 is the negative electrode. The first terminal of the second DC blocking circuit 403 is electrically connected to the first designated terminal 1011 of battery 101, and the second terminal of the second DC blocking circuit 403 is electrically connected to the grounding network. The first terminal of the fourth DC blocking circuit 405 is electrically connected to the third designated terminal 1013 of battery 101, and the second terminal of the fourth DC blocking circuit 405 is electrically connected to the grounding network.

[0071] It should be noted here that... Figure 10 For example only, there are also cases where the first designated terminal 1011 of the battery 101 is the negative electrode and the second designated terminal 1012 of the battery 101 is the positive electrode.

[0072] Figure 11 This is a schematic diagram illustrating the wearing of smart glasses according to an embodiment of this disclosure. Figure 11 As shown, the smart glasses are worn on a human head model. The smart glasses include a left temple cover, a right temple cover, a left port, and a right port.

[0073] Figure 12 This is a schematic diagram illustrating the wearing of smart glasses according to another embodiment of this disclosure. Figure 12 As shown, the plastic portion is hidden, revealing the location of the battery. Figure 12 As shown, the left battery of the smart glasses acts as an antenna, and the right battery of the smart glasses also acts as an antenna.

[0074] Figure 13 This is a schematic diagram illustrating the simulation efficiency of smart glasses according to an embodiment of this disclosure. Figure 13 As shown, the solid line represents the free space (FS) efficiency, and the dashed line represents the head state efficiency.

[0075] FS efficiency refers to the antenna efficiency of smart glasses in free space, such as when the smart glasses are held in hand or placed open on a wooden table.

[0076] Head-position efficiency refers to the antenna efficiency of smart glasses when worn normally. When wearing smart glasses, the antenna is close to the wearer's head, which affects antenna performance and causes a decrease in performance. The head's influence on antenna performance stems from two main aspects: firstly, the head acts as a lossy medium, absorbing some of the antenna's radiated signal and impairing communication signals; secondly, the head's proximity to the antenna changes the antenna's transmission environment, causing a shift in the antenna's input impedance, resulting in impedance mismatch and consequently affecting antenna efficiency.

[0077] like Figure 13 As shown, with the left battery as the antenna, the FS efficiency is -0.62dB and the head-state efficiency is -5.32dB. The absolute difference between the FS efficiency and the head-state efficiency is 4.7dB, meaning that the head-state efficiency decreases by 4.7dB relative to the FS efficiency. In other words, the head-state effect is 4.7dB. Thus, the head-state effect is less than 5dB.

[0078] Figure 14 This is a schematic diagram illustrating the simulation efficiency of smart glasses according to another embodiment of this disclosure. Figure 14 As shown, the solid line represents the FS efficiency, and the dashed line represents the head-state efficiency. With the right battery as the antenna, the FS efficiency is -0.87dB, and the head-state efficiency is -5.6dB. The absolute difference between the FS efficiency and the head-state efficiency is approximately 4.7dB, meaning that the decrease in head-state efficiency relative to the FS efficiency is approximately 4.7dB. In other words, the head-state effect is 4.7dB. Thus, the head-state effect is less than 5dB.

[0079] Table 1 shows a comparison of the impact of the human head on antenna performance between traditional AI glasses and the battery-based AI glasses of this disclosure.

[0080] Table 1 Comparison of the impact of human heads on antenna performance

[0081] As shown in Table 1, in AI glasses with batteries as antennas, the absolute difference between head efficiency and FS efficiency is 5dB, while in traditional antennas, the absolute difference between head efficiency and FS efficiency is 7dB.

[0082] Compared to traditional antennas, the use of batteries as antennas in this disclosure offers a significant performance improvement, and the head effect is controlled to around 5dB, which is 2dB better than the 7dB head effect of traditional antennas.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of this disclosure and to enable those skilled in the art to understand this disclosure and to design various embodiments with various modifications suitable for a particular purpose.
