TECHNICAL FIELD

[0001] The present application relates to the technical field of smart wearable devices, in particular to a pair of glasses. BACKGROUND

[0002] Currently, the concept of metaverse is gradually emerging, and more and more manufacturers are beginning to explore this field, resulting in a proliferation of glasses products. Since glasses need to be worn for a long time, the volume and weight of the glasses need to be controlled when designing the glasses, so the available space left for the antenna module is very limited. The antenna module is used to realize the communication between the glasses and external devices, such as realizing the communication connection between the glasses and the router through the antenna module. In the prior art, the antenna module is usually arranged on the temple of the glasses. On the one hand, the signals transmitted between the antenna module and the external device will be weakened by the user's head when the antenna module is arranged on the temple, and on the other hand, the frequency band of the antenna module is narrow due to the limited space of the temple, which slows down the communication rate between the glasses and the external device, affecting the performance of the glasses. SUMMARY

[0027] The core of this invention is to provide a pair of glasses that ensures sufficient available space for the antenna module, thereby enabling the antenna module to operate in a wider frequency band and improving the performance of the glasses.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a pair of glasses provided by the present invention. The glasses include:

[0030] The frame 1, the motherboard 2, and the antenna module are included. The frame 1 includes a left frame 1, a right frame 1, and a connecting part connecting the left frame 1 and the right frame 1. The antenna module includes a first antenna module and a second antenna module.

[0031] The motherboard 2 is located inside the connecting part and is used to control the first antenna module and the second antenna module to transmit and receive electromagnetic waves.

[0032] The first antenna module and the second antenna module are respectively arranged at the inner edge of the left frame 1 and the inner edge of the right frame 1.

[0033] In the prior art, the antenna module is usually arranged on the temple of the glasses, which on the one hand causes the antenna module to be weakened when receiving and transmitting electromagnetic waves by the user's head, and on the other hand the limited position on the temple causes the design of the antenna module to be limited, ultimately causing the frequency band of the antenna module to be relatively low, and also causing a relatively large burden to the user's ears, affecting the user experience.

[0034] Therefore, in the present application, the antenna module is arranged in the area corresponding to the frame 1 of the glasses, and the available space in the frame 1 is much larger than the available space on the temple, thereby meeting the requirement of occupying more available space when the frequency band of the antenna module is improved. Specifically, the glasses in the present application include a frame 1, a main board 2 and an antenna module, and the present application does not particularly limit the specific size and shape of the frame 1, as long as the frame 1 includes the left lens 501, the right lens 502 and the connecting part connecting the left lens 501 and the right lens 502, which can install the antenna module and the lens.

[0035] In order to realize the basic function of the glasses, the main board 2 also needs to be arranged, which is used to control the first antenna module and the second antenna module to send and receive electromagnetic waves, for example, after receiving the instruction triggered by the user to control the glasses to be connected with the router, the first antenna module and the second antenna module are controlled to generate electromagnetic waves for establishing the connection between the glasses and the router. The main board 2 can be realized by welding various chips and elements on the PCB board, and the present application does not particularly limit this.

[0036] The first antenna module and the second antenna module are respectively arranged at the edge of the left frame 1 and the edge of the right frame 1, for example, the first antenna module is arranged at the right edge of the left frame 1, and the second antenna module is arranged at the left edge of the right frame 1, and the space occupied by the first antenna module and the second antenna module is minimized on the basis of ensuring that the frequency band of the first antenna module and the second antenna module meets the requirements, thereby minimizing the influence of the first antenna module and the second antenna module on the field of view. Since the first antenna module and the second antenna module are both arranged in the frame 1 in the present application, there is enough available space to realize the full coverage of 2.4GHZ, 5GHZ and 7GHZ by the first antenna module and the second antenna module, greatly improving the rate of data transmission between the glasses and external devices and improving the performance of the glasses.

[0037] In summary, the glasses provided in the application include a frame 1, a main board 2 and an antenna module. The main board 2 is arranged in the connecting part of the left frame 1 and the right frame 1 in the frame 1, and controls the antenna module to send and receive electromagnetic waves to meet the communication requirement of the glasses with external devices. The first antenna module and the second antenna module in the antenna module are arranged at the inner edges of the left frame 1 and the right frame 1 of the frame 1 respectively, so as to ensure that the antenna module has sufficient available space, meet the requirement of the antenna module for available space when the frequency band is improved, and reduce the influence of the head of the user on the receiving and sending of electromagnetic waves by the antenna module, and further improve the performance of the glasses.

[0038] On the basis of the above embodiment,

[0039] As a preferred embodiment, the first antenna module and the second antenna module each include a radiation sheet 301, a parasitic unit 302 and a coaxial line 303.

[0040] The parasitic unit 302 is in the shape of a rectangle and has an L-shaped hole inside. The radiation sheet 301 is in the shape of a rectangle and is arranged in the area of the L-shaped hole of the parasitic unit 302.

[0041] One end of the coaxial line 303 is connected with the radiation sheet 301, and the other end is connected with the main board 2.

[0042] The coaxial line 303 is used to transmit the control signal sent by the main board 2 to the first antenna module and the second antenna module, so that the first antenna module and the second antenna module generate electromagnetic waves corresponding to the control signal, and transmit the electromagnetic waves sent by the first antenna module and the second antenna module to the main board 2, so that the main board 2 controls the glasses to perform corresponding operations based on the electromagnetic waves.

[0043] In the embodiment, the first antenna module and the second antenna module have the same structure and each include a radiation sheet 301, a parasitic unit 302 and a coaxial line 303. The overall shape of the parasitic unit 302 is a rectangle, and an L-shaped hole is arranged inside. The overall shape of the radiation sheet 301 is also a rectangle and is arranged in the L-shaped hole of the parasitic unit 302. Therefore, by adjusting the size of the radiation sheet 301 and the interval between the radiation sheet 301 and the parasitic unit 302, the wavelength of the electromagnetic waves generated by the antenna module can be changed, and the frequency band covered by the glasses can be changed. For example, by adjusting the length and width of the radiation sheet 301, Wi-Fi signals can be fully covered at 5GHZ and 7GHZ. By adjusting the size of the parasitic unit 302, Wi-Fi signals can be covered at 2.4GHZ. The principle of the antenna is a monopole antenna plus a parasitic antenna. The process of generating electromagnetic waves is not described here.

[0044] Please refer to Figure 2 and Figure 3 , Figure 2A structure diagram of a first antenna module in glasses provided by the application, Figure 3 A structure diagram of a second antenna module in glasses provided by the application, Figure 2 and Figure 3 The first antenna module and the second antenna module provided by the application are an implementation mode in which the antenna module can realize full coverage of 2.4GHZ, 5GHZ and 7GHZ, and the size thereof can be adjusted according to actual use scenarios.

[0045] Please refer to Figure 4 and Figure 5 , Figure 4 A performance test waveform diagram of the first antenna module in glasses provided by the application, Figure 5 A performance test waveform diagram of the second antenna module in glasses provided by the application. Figure 4 and Figure 5 The vertical axis in each of the performance test waveform diagrams is an index parameter, and the horizontal axis is the frequency of electromagnetic waves. When the index parameter is less than 2, it proves that the performance of the antenna module in the frequency band is better. It can be seen that the first antenna module and the second antenna module in the application can realize full coverage of 2.4GHZ, 5GHZ and 7GHZ.

[0046] The material of the parasitic unit 302 and the radiation sheet 301 is not particularly limited in the application, and for example, can be a conductive material such as copper. Furthermore, the medium substrate on which the radiation sheet 301 and the parasitic unit 302 are located can be a transparent and non-conductive material, which further ensures that the user's field of view is not blocked and improves the user experience.

[0047] As a preferred embodiment, the length of the radiation sheet 301 is one fourth of the wavelength of the electromagnetic wave with the longest wavelength in the target frequency band of the glasses.

[0048] In the embodiment, when the length of the radiation sheet 301 in the antenna is one fourth of the wavelength of the electromagnetic wave, the efficiency of the antenna in transmitting and receiving electromagnetic waves is the highest, so the length of the radiation sheet 301 in the antenna can be determined according to the wavelength of the electromagnetic wave with the longest wavelength in the target frequency band of the glasses. The target frequency band of the glasses is not particularly limited in the application and can be adjusted according to actual conditions.

[0049] As a preferred embodiment, a screw 4 made of metal is further included, and a circular hole is arranged on the parasitic unit 302.

[0050] The screw 4 fixes the first antenna module and the second antenna module on the mainboard 2 through the circular hole on the parasitic unit 302.

[0051] Please refer to Figure 2 and Figure 3 , Figure 2A structure diagram of a first antenna module in glasses provided by the present application, Figure 3 A structure diagram of a second antenna module in glasses provided by the present application, Figure 2 The circle located at the upper right corner in the figure is the mounting position of the screw 4, and a corresponding hollow is also provided on the mainboard 2. Figure 3 The circle located at the upper left corner in the figure is also the circular hollow, that is, the mounting position of the screw 4, and a corresponding hollow is also provided on the mainboard 2.

[0052] It should be noted that in the embodiment, the screw 4 plays a role of mounting and fixing the first antenna module and the second antenna module on the mainboard 2, and on the other hand, since the screw 4 is made of a conductive metal material, the screw 4 can also be used as a grounding point of the first antenna module and a grounding point of the second antenna module, thereby reducing the cost of the glasses.

[0053] As a preferred embodiment, the screw 4 is also used to fix the mainboard 2 on the connecting portion of the frame 1.

[0054] In the embodiment, the length of the screw 4 is further prolonged, and in addition to being used to arrange the first antenna module and the second antenna module on the mainboard 2, the screw 4 can also be used to fix the mainboard 2 on the connecting portion of the frame 1, thereby further reducing the complexity of the design of the glasses and reducing the cost of the glasses.

[0055] As a preferred embodiment, the glasses further comprise a left temple 601 connected to the left frame 1, a right temple 602 connected to the right frame 1, a left lens 501 arranged on the left frame 1, and a right lens 502 arranged on the right frame 1, and the material of the left temple 601, the material of the right temple 602, and the material of the frame 1 are all insulating materials.

[0056] In the embodiment, the glasses further comprise the left temple 601 and the right temple 602 to meet the needs of users wearing glasses, and in order to reduce the influence of the glasses body on the reception and transmission of electromagnetic waves by the first antenna module and the second antenna module, the left temple 601, the right temple 602, the left frame 1, and the right frame 1 are all made of insulating materials such as plastic.

[0057] In addition, the left lens 501 and the right lens 502 are arranged on the left frame 1 and the right frame 1 respectively, and since the first antenna module and the second antenna module are also arranged at the inner edges of the left frame 1 and the right frame 1 respectively, it is necessary to ensure that the left lens 501 and the first antenna module are located at different layers, and the right lens 502 and the second antenna module are located at different layers, and the present application does not make a special limitation on whether the left lens 501 is arranged at an inner layer or an outer layer relative to the first antenna module. Figure 1 Figure 1 A structure diagram of glasses provided by the present application, in​Figure 1 The left lens 501 and the right lens 502 are provided with certain protrusions on the edges thereof so as to arrange the first antenna module and the second antenna module in the inner layer and arrange the left lens 501 and the right lens 502 in the outer layer.

[0058] As a preferred embodiment, a power supply device arranged on the left temple 601 or the right temple 602 is further included for supplying power to the mainboard 2.

[0059] Considering that the mainboard 2 needs to be supplied with power to realize the functions of the glasses, a power supply device is further arranged in the embodiment, and the specific structure of the power supply device is not particularly limited in the present application, but the arrangement position of the power supply device is on the left temple 601 or the right temple 602 of the glasses, thereby balancing the weight of the mainboard 2 arranged in the front end connecting portion of the glasses, so that the user wears the glasses more stably.

[0060] As a preferred embodiment, the first antenna module and the second antenna module are both FPC type antennas or LDS type antennas or steel sheet antennas.

[0061] The first antenna module and the second antenna module have multiple implementation forms in the embodiment, wherein the FPC type antenna and the steel sheet antenna are equivalent to pulling out the antenna circuit on the PCB board and using other external metal to make an antenna, which has the advantages of small size, good performance and low cost; the LDS type antenna can fully utilize the three-dimensional space, thereby reducing the size of the first antenna module and the second antenna module. It should be noted that when the above three types of antennas are used, there are certain differences in the size requirements of the parasitic unit 302 and the radiation sheet 301 in the antenna, which can be adjusted according to the actual situation.

[0062] As a preferred embodiment, a heat dissipation module arranged in the connecting portion is further included for dissipating heat for the mainboard 2 when it is detected that the temperature of the mainboard 2 is greater than a preset temperature threshold.

[0063] Considering that the mainboard 2 may generate a large amount of heat under the condition of long-time work or heavy work task of the glasses, and since the mainboard 2 is arranged in the inner layer of the connecting portion, the heat dissipation of the mainboard 2 is relatively slow, therefore, the heat dissipation module is further arranged in the connecting portion in the embodiment, which can automatically detect the temperature of the mainboard 2 and dissipate heat for the mainboard 2 when the temperature of the mainboard 2 is greater than a preset temperature threshold, and the specific structure of the preset temperature threshold and the heat dissipation module is not particularly limited in the present application.

[0064] As a preferred embodiment, the mainboard 2 is further used for detecting whether the first antenna module and the second antenna module can normally send and receive electromagnetic waves, and generating a fault prompt information when it is detected that there is a fault antenna module that cannot normally send and receive electromagnetic waves.

[0065] In view of the fact that the first antenna module and the second antenna module in the glasses can not be able to normally receive or send electromagnetic waves, the main board 2 is further configured to detect whether the first antenna module and the second antenna module can normally send and receive electromagnetic waves, and generate a fault prompt information when detecting that there is a fault antenna module that cannot normally send and receive electromagnetic waves, wherein the fault prompt information can be information indicating the number of the specific antenna module in the first antenna module and the second antenna module that has a fault.

[0066] In addition, the present application does not particularly limit how to detect whether the first antenna module and the second antenna module can normally send and receive electromagnetic waves. For example, when it is detected that one of the first antenna module and the second antenna module receives electromagnetic waves, but the other one does not receive electromagnetic waves, it is preliminarily determined that the antenna module that does not receive electromagnetic waves is a fault antenna module, and in order to further determine whether the judgment result is correct, the fault antenna module can be controlled to send electromagnetic waves to detect whether it can normally send electromagnetic waves. For example, when it is necessary to detect whether the first antenna module and the second antenna module can normally send electromagnetic waves, the main board 2 generates a test signal, and then detects whether the external device in communication with the main board 2 receives the electromagnetic waves sent by the first antenna module and the second antenna module and replies to the relevant receiving information.

[0067] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the various embodiments can be referred to each other. In the specification, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the statement "including a" does not exclude the presence of another identical element in the process, method, article or device including the element.

[0068] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
