The entire contents of that application are incorporated by reference into this application. Technical Field

[0003] The present application belongs to the technical field of electronic equipment, and specifically relates to a wearable device. Background Art

[0004] With the development of technology, the types of electronic devices are becoming more and more diverse, including common mobile phones and tablets, as well as wearable devices such as smart watches and smart glasses. Taking smart glasses as an example, they can provide the ability to expand reality by setting up structures such as display modules. In current smart glasses, slot antennas are usually formed on the metal frame, and the slot antennas extend to the edge of the metal frame. Based on this, in order to ensure that the metal frame can still be connected as a whole, corresponding dielectric materials are usually filled in the slot antenna so that the multiple parts of the metal frame divided by the slot antenna can still be reconnected as a whole. However, the structural strength of this metal frame is still relatively low, which has an adverse effect on the structural reliability of the wearable device. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a wearable device to solve the problem that the slot antenna in the metal frame of the current wearable device extends to the edge of the metal frame, resulting in relatively poor structural reliability of the metal frame.

[0006] An embodiment of the present application provides a wearable device, which includes a device body and support legs connected to both sides of the device body, the device body includes a metal frame, the metal frame is provided with a first antenna and a second antenna, the first antenna and the second antenna are both slot antennas, and the edges of the first antenna and the second antenna are respectively spaced apart from the edges of the metal frame, the first antenna can be used to receive and / or transmit wireless signals in a first frequency band, and the second antenna can be used to receive and / or transmit wireless signals in a second frequency band, and the second frequency band is larger than the first frequency band.

[0007] The present application discloses a wearable device having support legs on both sides of the device body to facilitate wearing of the device by the user, and the device body includes a metal frame, thereby improving the overall structural strength of the device body and significantly improving the heat dissipation performance of the device body, thereby also improving the wireless signal receiving and transmitting performance of the wearable device. At the same time, a first antenna and a second antenna are provided on the metal frame, both of which are slot antennas, so that the first antenna and the second antenna can serve as antennas in the wearable device to receive and / or transmit signals. The first antenna is used to receive and / or transmit wireless signals in a first frequency band, and the second antenna is used to receive and / or transmit wireless signals in a second frequency band.

[0015] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0016] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0017] As shown in Figures 1-5, embodiments of the present application disclose a wearable device, which may specifically be glasses. The wearable device includes a device body 100 and support legs 200, with support legs 200 connected to both sides of the device body 100. The support legs 200 enable the user to use the support legs 200 to establish a relatively stable relative fixed relationship between the wearable device and the eye, making it easier for the user to use the wearable device. Specifically, the support legs 200 may be foldable or non-foldable, and may be formed of materials such as plastic or metal, which are not limited herein.

[0018] The device body 100 is the main structure of the wearable device, which may include a metal frame 110. Of course, the device body may also include other devices such as a radio frequency transceiver (not shown in the figure). A glass cover 150 may be provided on the outside of the metal frame 110 to shield the internal components of the device body 100, thereby integrating the appearance of the device. Of course, the device body 100 may also include devices such as a battery 310, a display module 160 and a circuit board (not shown in the figure). Optionally, the device body 100 also includes other electronic devices such as a camera module 170 and an audio component 320 that enhance human-computer interaction capabilities. In order to reduce the overall size of the device body 100 and take into account the center of gravity of the entire wearable device, devices such as the battery 310 and the audio component 320 may be installed inside the support leg 200.

[0019] Based on the above-mentioned device body 100 including the metal frame 110, in order to enable the RF transceiver to normally use the metal frame 110 to receive and transmit wireless signals, as shown in Figures 3 and 5, the metal frame 110 disclosed in the embodiment of the present application is provided with a first antenna 110a and a second antenna 110b, and the first antenna 110a and the second antenna 110b are both slot antennas, and the first antenna 110a and the second antenna 110b are both connected to the RF transceiver, so that the first antenna 110a and the second antenna 110b can be used as devices for receiving and transmitting wireless signals, that is, antennas. In other words, the first antenna 110a and the second antenna 110b are used as slot antennas. In addition, the first antenna 110a and the second antenna 110b can specifically be wireless network antennas, that is, Wi-Fi antennas, so that the wearable device can use the first antenna 110a and the second antenna 110b for wireless network communication.

[0020] At the same time, in order to expand the coverage range of the wearable device disclosed in the embodiment of the present application for the frequency band of wireless signals, in the embodiment of the present application, the slit lengths of the first antenna 110a and the second antenna 110b can be designed so that the first antenna 110a, when used as an antenna, can be used to receive and / or transmit wireless signals in the first frequency band, and the second antenna 110b, when used as an antenna, can be used to receive and / or transmit wireless signals in the second frequency band, and the second frequency band is greater than the first frequency band.

[0021] It should be noted that the first frequency band and the second frequency band are not necessarily frequencies of a specific value. Both can be a set of frequencies between two frequency values, and the frequencies included in the second frequency band are all greater than the frequencies included in the first frequency band. For example, the first frequency band can be a plurality of frequencies included in 2.4 GHz, and correspondingly, the second frequency band can be a plurality of frequencies included in 5 GHz. In this case, the wireless communication performance of the wearable device can be improved. Of course, under corresponding requirements, the first frequency band and the second frequency band can also use other frequencies, which is not limited in this document.

[0022] As described above, in actual applications, the slot sizes of the first antenna 110a and the second antenna 110b can be designed so that they can each receive and / or transmit wireless signals of corresponding frequencies. In other embodiments of the present application, the corresponding structures of the first antenna 110a and the second antenna 110b can also be designed so that, under certain specific conditions, they can each receive and / or transmit wireless signals of the first frequency band and the second frequency band, respectively. If the conditions corresponding to the structures of the first antenna 110a and the second antenna 110b change, the first antenna 110a and the second antenna 110b may also each be capable of receiving wireless signals of other frequency bands. This will be described in detail below. That is, in the present application, the first antenna 110a being capable of receiving and / or transmitting wireless signals of the first frequency band is merely an introduction to its capabilities, and does not limit the frequencies of the wireless signals it can receive. Similarly, the description of the second antenna 110b is the same.

[0023] During the design process of the wearable device disclosed in the embodiments of this application, the slot lengths of the first antenna 110a and the second antenna 110b can be adaptively designed based on the specific parameters of the desired antenna frequency band, and the two antennas can be extended at corresponding positions. Optionally, at least one of the first antenna 110a and the second antenna 110b can extend from the middle position of the metal frame 110 to the edge position of the metal frame 110, thereby reducing the processing difficulty of the first antenna 110a and the second antenna 110b during the processing and improving the antenna performance to a certain extent.

[0024] To enhance the overall structural strength and reliability of the metal frame 110, in another embodiment of the present application, the edges of the first antenna 110a and the second antenna 110b can be spaced apart from the edges of the metal frame 110. For example, if the metal frame 110 is a single piece of metal sheet, the first antenna 110a and the second antenna 110b can be located inward of the outer edge of the metal frame 110. In other words, the first antenna 110a and the second antenna 110b are both closed antenna structures, neither extending to or connected to the outer edge of the metal frame 110. Of course, if the metal frame 110 has an inner hole or other structure, the edge of the inner hole is also part of the edge of the metal frame 110. Accordingly, the first antenna 110a and the second antenna 110b are also spaced apart from the edge of the inner hole, so that neither the first antenna 110a nor the second antenna 110b is connected to the edge of the inner hole. When this technical solution is adopted, the overall appearance of the wearable device can also be improved.

[0025] The embodiment of the present application discloses a wearable device, wherein support legs 200 are provided on opposite sides of the device body 100 to facilitate the user to wear the device, and the device body 100 includes a metal frame 110, thereby improving the overall structural strength of the device body 100 and significantly improving the heat dissipation performance of the device body 100, thereby also improving the wireless signal receiving and transmitting performance of the wearable device. At the same time, a first antenna 110a and a second antenna 110b are provided on the metal frame 110, both of which are slot antennas, so that the first antenna 110a and the second antenna 110b can be used as antennas in the wearable device to receive and / or transmit signals. Among them, the first antenna 110a is used to receive and / or transmit wireless signals in a first frequency band, and the second antenna 110b is used to receive and / or transmit wireless signals in a second frequency band. The second frequency band is larger than the first frequency band, so that the wearable device has relatively good frequency band compatibility with wireless signals, thereby improving the user experience of the wearable device. Moreover, in the wearable device disclosed in the embodiment of the present application, the edges of the first antenna 110a and the second antenna 110b are spaced apart from the edge of the metal frame 110, that is, the first antenna 110a and the second antenna 110b are both located as a whole within the outer edge of the metal frame 110, so that the outer edge of the metal frame 110 with a multi-band antenna is still a complete closed ring structure, making the structural stability of the metal frame 110 relatively high, thereby improving the service life of the entire wearable device.

[0026] As described above, the first antenna 110a and the second antenna 110b are both disposed on the metal frame 110. To this end, the first antenna 110a and the second antenna 110b can be disposed in the middle of the metal frame 110. Alternatively, as described above, the wearable device can be specifically a pair of glasses. In this case, to make the wearable device more adaptable to the user's face, the device body 100 of the wearable device and the middle of the metal frame 110 included therein are generally provided with an area to avoid the user's nose bridge, thereby roughly dividing the metal frame 110 into portions corresponding to the user's left eye and right eye, respectively. To this end, one of the first antenna 110a and the second antenna 110b can be disposed on the portion of the metal frame 110 corresponding to the user's left eye, and the other can be disposed on the portion of the metal frame 110 corresponding to the user's right eye.

[0027] In order to minimize the adverse effects of the user's head on the antenna performance of the wearable device, in another embodiment of the present application, optionally, as shown in Figures 3 and 5, at least one of the first antenna 110a and the second antenna 110b is located in the edge area of ​​the metal frame 110 close to the supporting leg 200. In this case, when the wearable device is used by the user, the distance between one or both of the first antenna 110a and the second antenna 110b located in the edge area and the user's cheek and nose bridge is relatively small, thereby improving the radiation efficiency of the antenna.

[0028] It should be noted that, compared to the distance between the portion of the metal frame 110 near the area of ​​the metal frame 110 that avoids the user's nose bridge and the support leg 200, the portion of the metal frame 110 near the support leg 200 is relatively smaller. The portion of the metal frame 110 near the support leg 200 is the aforementioned edge region. However, the first antenna 110a and the second antenna 110b disposed in the edge region of the metal frame 110 near the support leg 200 still have a spacing greater than zero from the outermost edge of the metal frame 110. In other words, the first antenna 110a and the second antenna 110b are both enclosed hole-like or slot-like structures disposed in the metal frame 110. That is, the edges of the first antenna 110a and the second antenna 110b can still be spaced apart from the edge of the metal frame 110. The specific value of the distance between the first antenna 110a and / or the second antenna 110b and the outermost edge of the metal frame 110 close to the support leg 200 can be flexibly determined according to actual needs and is not limited herein.

[0029] Specifically, one of the first antenna 110a and the second antenna 110b can be extended along the left or right edge of the metal frame 110, and the other can be extended along the upper or lower edge of the metal frame 110, thereby ensuring that the antenna radiation efficiency of both is relatively high. In addition, in the embodiment of the present application, the first antenna 110a and the second antenna 110b can both be arranged on the portion of the metal frame 110 corresponding to the user's left eye (or right eye), or one of the first antenna 110a and the second antenna 110b can be arranged on the portion of the metal frame 110 corresponding to the user's left eye, and the other can be arranged on the portion of the metal frame 110 corresponding to the user's right eye.

[0030] Taking into account that the wearable device may be affected by factors such as the user's state during use, resulting in the user's head being blocked between the first antenna 110a and / or the second antenna 110b and wireless signal transceiver devices such as routers, resulting in a decrease in the radiation efficiency of the antenna, in another embodiment of the present application, optionally, as shown in Figure 4, in the wearable device disclosed in the embodiment of the present application, one of the edge areas of the metal frame 110 close to the two supporting legs 200 is provided with a first groove 111, and the other is provided with a second groove 112, that is, the metal frame 110 is provided with a first groove 111 in an edge area close to one supporting leg 200, and the metal frame 110 is provided with a second groove 112 in an edge area close to the other supporting leg 200, which makes the first groove 111 and The slot antennas included in the second slot body 112 are basically not blocked by the user's cheeks and nose bridge, so as to improve the radiation performance of each antenna; at the same time, by making the first slot body 111 and the second slot body 112 both include the first slot 113 and the second slot 114, and by making each first slot 113 can be used to receive and / or transmit wireless signals in the first frequency band, and making each second slot 114 can be used to receive and / or transmit wireless signals in the second frequency band, the first slot body 111 and the second slot body 112 can each independently have the ability to receive wireless signals in the first frequency band and the second frequency band, and further, during the use of the device, it can be ensured that at least one of the first slot body 111 and the second slot body 112 will not be blocked by the front of the user's head, thereby improving the robustness of the antenna performance of the wearable device.

[0031] Furthermore, in the process of designing the first slot body 111 and the second slot body 112, the first slot body 111 and the second slot body 112 can be symmetrically arranged, which can reduce the difficulty of processing the first slot body 111 and the second slot body 112. Of course, in other embodiments of the present application, the first slot body 111 and the second slot body 112 can also be asymmetrically arranged. In addition, for the first antenna 110a in the first slot body 111 and the second slot body 112 respectively used to receive the first frequency band, the polarization directions of the two can be the same, such as both are horizontally polarized or vertically polarized; similarly, for the second antenna 110b in the first slot body 111 and the second slot body 112 respectively used to receive the second frequency band, the polarization directions of the two can also be the same, such as both are horizontally polarized or both are vertically polarized.

[0032] In another embodiment, the polarization directions of the first antennas 110a of the first slot body 111 and the second slot body 112 can be made perpendicular to each other, and the polarization directions of the second antennas 110b of the first slot body 111 and the second slot body 112 can be made perpendicular to each other. In this case, the isolation and envelope correlation coefficient between each first antenna 110a and each second antenna 110b can be relatively good, thereby improving the performance of the multiple input multiple output (MIMO) antenna.

[0033] In the above-mentioned metal frame 110 including the first slot body 111 and the second slot body 112, in order to further improve the isolation between the two first antennas 110a both used to receive wireless signals in the first frequency band, and to improve the isolation between the two second antennas 110b both used to receive wireless signals in the second frequency band, in a specific embodiment of the present application, the polarization direction of the first antenna 110a of the first slot body 111 can be made perpendicular to the polarization direction of the first antenna 110a of the second slot body 112, and the polarization direction of the second antenna 110b of the first slot body 111 can be made perpendicular to the polarization direction of the second antenna 110b of the second slot body 112. That is, the polarization directions of the antennas (i.e., the first slot 113) in the first slot body 111 and the second slot body 112 for receiving and / or transmitting the first frequency band are respectively arranged orthogonally, and the polarization directions of the antennas (i.e., the second slot 114) in the first slot body 111 and the second slot body 112 for receiving and / or transmitting the second frequency band are also arranged orthogonally, thereby further improving the performance of the MIMO antenna.

[0034] Based on the above embodiment, the structures of the first slot body 111 and the second slot body 112 can optionally be asymmetrically arranged. For example, the polarization direction of the first slot in the first slot body 111, which serves as the first antenna 110a, can be vertical, and the polarization direction of the second slot in the second slot body 112, which serves as the second antenna 110b, can be horizontal. Correspondingly, the polarization direction of the first slot in the second slot body 112, which serves as the first antenna 110a, can be horizontal, and the polarization direction of the second slot in the second slot body 112, which serves as the second antenna 110b, can be vertical. This ensures that the polarization directions of the two first antennas 110a and the two second antennas 110b are perpendicular to each other.

[0035] Specifically, in the process of arranging the first trough body 111 and the second trough body 112, the extension direction of the first slit 113 in the first trough body 111 can be perpendicular to the extension direction of the first slit 113 in the second trough body 112 or substantially perpendicular to each other; correspondingly, the extension direction of the second slit 114 in the first trough body 111 can be perpendicular to the extension direction of the second slit 114 in the second trough body 112 or substantially perpendicular to each other.

[0036] In order to make the polarization direction of the first antenna 110a of the first slot body 111 perpendicular to the polarization direction of the first antenna 110a of the second slot body 112, and to make the polarization direction of the second antenna 110b of the first slot body 111 perpendicular to the polarization direction of the second antenna 110b of the second slot body 112, in another embodiment of the present application, the structure of the wearable device, specifically the structure or matching components of the first slit 113 and the second slit 114, can also be designed to increase the range of frequency bands of wireless signals that can be received by the first slit 113 and the second slit 114, and by using different control conditions, so that the first slit 113 and the second slit 114 each have the ability to separately receive and / or transmit the first frequency band and the second frequency band.

[0037] Specifically, the lengths of the first and second slots 113, 114 extending on the metal frame 110 can be relatively large, so that both have the ability to cover wireless signals in the first frequency band. In this case, a controllable on / off device, such as a switch, can be provided at a corresponding position between the ends of each first slot 113 and each second slot 114. When the switch is closed, the switch acts as a conductive element to reduce the effective length of the portion of the first and second slots 113, 114 that serves as the slot antenna, so that the length of the portion between the feed point of each first slot 113 and the switch of each second slot 114 meets the conditions for receiving and / or transmitting wireless signals in the second frequency band. When the switch is open, the opposing sides of the first and second slots 113, 114 are blocked from conducting, so that the length of the portion between the feed point and the end of each first slot 113, 114 meets the conditions for receiving and / or transmitting wireless signals in the first frequency band. In this case, by controlling the on / off states of each switch, the first slot 113 and the second slot 114 of the first slot body 111 and the second slot body 112 can be used to receive and / or transmit wireless signals in the first frequency band and the second frequency band, respectively, under different conditions. Of course, the specific positions of the above switches can be flexibly determined based on parameters such as the specific lengths of the first slots 113 and the second slots 114, the locations of the feeding points, and whether other dielectric materials are used. This will be described in detail below.

[0038] In more detail, in the wearable device disclosed in the embodiment of the present application, the device body 100 also includes a first switch 121 and a second switch 122, and each first slit 113 is provided with a first switch 121, and each second slit 114 is provided with a second switch 122, so that by controlling the on and off status of each first switch 121 and the second switch 122, the frequency band of the wireless signal that the first slit 113 and the second slit 114 can receive and / or transmit is correspondingly controlled.

[0039] Specifically, when the first switch 121 is disconnected, the length of the first slot 113 is relatively long, enabling it to receive and / or transmit wireless signals in the first frequency band. When the first switch 121 is closed, a portion of the first slot 113 is disconnected from another portion of the first slot 113 due to the conduction of the first switch 121, enabling the portion of the first slot 113 between the feed point and the first switch 121 to receive and / or transmit wireless signals in the second frequency band. Correspondingly, when the second switch 122 is disconnected, the second slot 114 can receive and / or transmit wireless signals in the first frequency band, and when the second switch 122 is closed, the second slot 114 can receive and / or transmit wireless signals in the second frequency band. In this case, the first slot 113 and the second slot 114 can each independently serve as the first antenna 110a and the second antenna 110b.

[0040] Based on the above embodiment, when the metal frame 110 includes a first slot body 111 and a second slot body 112, and the first slot body 111 and the second slot body 112 both include a first slit 113 and a second slit 114, the above technical solution can be adopted to provide each first slit 113 and each second slit 114 with a first switch 121 and a second switch 122, so that by changing the states of the first switch 121 and the second switch 122, the polarization directions of the parts of the first slot body 111 and the second slot body 112 used to receive and / or transmit the first frequency band are perpendicular to each other, and the polarization directions of the parts of the first slot body 111 and the second slot body 112 used to receive and / or transmit the second frequency band are also perpendicular to each other.

[0041] Moreover, when the technical solution disclosed in the above embodiment is adopted, the positions of the parts for transmitting and receiving the first frequency band (and the second frequency band) in the first slot body 111 and the second slot body 112 can be changed by changing the states of the first switch 121 and the second switch 122 respectively provided in the first slot body 111 and the second slot body 112, so that the wearable device can switch the positions of the parts for receiving and / or transmitting the first frequency band and the second frequency band respectively according to the signal strength of the corresponding frequency band, thereby improving the antenna performance of the wearable device.

[0042] To reduce the difficulty of manufacturing the first and second slots 111 and 112 in the wearable device, optionally, when both the first and second slots 111 and 112 are provided with a first and second switches 121 and 122, the structures of the first and second slots 111 and 112 can be arranged symmetrically. Furthermore, in this case, to improve the performance of each first antenna 110a and each second antenna 110b, when the first switch 121 of the first slot 111 is closed, the second switch 122 of the first slot 111 can be opened, the first switch 121 of the second slot 112 can be opened, and the second switch of the second slot 112 can be closed. Furthermore, when the first switch 121 of the first slot 111 is open, the second switch 122 of the first slot 111 can be closed, the first switch 121 of the second slot 112 can be closed, and the second switch of the second slot 112 can be opened. In this case, it can be ensured that the polarization direction of the portion of the first slot body 111 used as the first antenna 110a is perpendicular to the polarization direction of the portion of the second slot body 112 used as the first antenna 110a, and it can be ensured that the polarization direction of the portion of the second slot body 112 used as the second antenna 110b is perpendicular to the polarization direction of the portion of the second slot body 112 used as the second antenna 110b.

[0043] As described above, a first slot body 111 and a second slot body 112 can be provided on the metal frame 110, and both of them include a first slit 113 and a second slit 114. At the same time, the first slit 113 and the second slit 114 can be used as antennas to receive wireless network signals, that is, the first slit 113 and the second slit 114 are both wireless network antennas. Based on this, in order to expand the connection capability between the wearable device and other devices and improve the scalability of the wearable device, optionally, as shown in FIG4 , the wearable device also includes an external device connection antenna 130, and by connecting the external device connection antenna 130 to the RF transceiver, the external device connection antenna 130 is used to receive and / or transmit wireless signals in the third frequency band, so that the wearable device can use the external device connection antenna 130 to connect to other devices outside the wearable device, so as to achieve the purpose of connecting the wearable device to the external device. Specifically, the external device can be a peripheral product such as a handle. In addition, the external device connection antenna 130 can be a PIFA antenna, that is, an antenna in an inverted F structure, and the wireless connection method it adopts can be a Bluetooth connection protocol. Of course, it can also adopt other structures and other wireless connection methods, which are not limited in this article.

[0044] In the process of laying out the external device connection antenna 130, the specific position of the external device connection antenna 130 can be flexibly set according to the specific device layout in the device body 100. In another embodiment of the present application, in order to ensure relatively good isolation between the antenna represented by the first slot body 111 and the second slot body 112 and the external device connection antenna 130, as shown in Figure 4, the external device connection antenna 130 can be set between the first slot body 111 and the second slot body 112. Moreover, when the first slot body 111 and the second slot body 112 are symmetrically arranged, by making the relative position of the external device connection antenna 130 and the first slot body 111 and the second slot body 112 the same or substantially the same, the isolation between the first slot body 111 and the external device connection antenna 130, as well as between the second slot body 112 and the external device connection antenna 130, can be further improved, thereby further improving the overall performance of each antenna in the wearable device.

[0045] As described above, the metal frame 110 may be provided with a first slot body 111 and a second slot body 112. In order to reduce the weight of the entire wearable device to a certain extent, optionally, as shown in FIG5 and in combination with FIG4, the metal frame 110 may also be provided with a weight-reducing hole 110c, and the weight-reducing hole 110c is located between the first slot body 111 and the second slot body 112. This significantly reduces the weight of the metal frame 110 while minimizing the impact on the structural strength of the metal frame 110, thereby achieving the purpose of reducing the weight of the wearable device and improving the user experience of the wearable device. In addition, when the above-mentioned weight-reducing hole 110c is provided, the coupling path between the first slot body 111 and the second slot body 112 can be further blocked, further improving the isolation between the two.

[0046] As described above, the metal frame 110 is provided with a first groove body 111 and a second groove body 112. Optionally, during the processing of the wearable device, a dielectric material can be filled in each of the first groove body 111 and the second groove body 112 to improve the integrity of the metal frame 110, thereby ensuring that the metal frame 110 has good structural reliability.

[0047] In this case, the lengths of the first antenna 110a and the second antenna 110b can be determined based on parameters such as the dielectric constant of the dielectric material being filled, and the specific ranges of the first and second frequency bands. If the metal frame 110 is provided with a first slot 111 and a second slot 112 including a first slit 113 and a second slit 114, the lengths of the first and second slits 113, 114, and the specific positions of the first and second switches 121, 122, respectively, provided on each first and second slit 113, 114 can also be determined accordingly based on the dielectric material being filled, to ensure that the first and second slits 113, 114 are capable of transmitting and receiving wireless signals in the first and second frequency bands under the corresponding conditions. For example, the first slit 113 and the second slit 114 can be filled with glass. In this case, to ensure that the first antenna 110a can cover 2.4 GHz wireless signals, the lengths of the first slit 113 and the second slit 114 can be approximately 35-40 mm, and the first switch 121 and the second switch 122 can be respectively provided at positions where the first slit 113 and the second slit 114 are spaced approximately 8-10 mm from the feed point. When the first switch 121 and the second switch 122 are closed, the first slit 113 and the second slit 114 function as the second antenna 110b, capable of covering 5 GHz wireless signals. Furthermore, the widths of the first slot 111 and the second slot 112 can be between 1 mm and 2 mm.

[0048] Optionally, the first antenna 110a and the second antenna 110b have a segmented structure, and the two can be connected to the RF transceiver by feeding them separately. In another embodiment of the present application, one end of the first antenna 110a and one end of the second antenna 110b can be connected, and the device body 100 also includes a feeding connection part 140, and then the feeding connection part 140 is connected to the connection between the first antenna 110a and the second antenna 110b, so that the first antenna 110a and the second antenna 110b can be fed at the same time, thereby reducing the number of components required to be set in the wearable device and reducing the difficulty of assembling the wearable device.

[0049] In addition, as described above, the metal frame 110 can include a first slot body 111 and a second slot body 112, and a first switch 121 and a second switch 122 can be respectively provided on the first slot 113 and the second slot 114 of the first slot body 111 and the second slot body 112. Based on this, by ensuring that the lengths of the first slot 113 and the second slot 114 can both cover the wireless signals of the first frequency band, and by ensuring that the first slot 113 and the second slot 114 of the first slot body 111 and the second slot body 112 are connected to each other, a feed connection portion can be provided at the connection between the two. When adopting the above technical solution, if the filling medium of the first slit 113 and the second slit 114 is still glass, in the process of simulating the S parameters and simulation efficiency of the antenna, the first slit 113 and the second slit 114 can also be applied to the relevant frequency band of 7GHz, so that the antenna can cover frequency bands such as 2.4GHz, 5.1GHz, 5.8GHz, 6GHz (5.925~7.125GHz), thereby meeting the frequency band requirements of Wi-Fi6E and Wi-Fi7, further expanding the frequency band range supported by wearable devices, improving the stability and reliability of their data transmission, and reducing latency.

[0050] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
