[0044] With the rapid development of science and technology, various smart watches have been used in people's daily lives. In addition to traditional watch functions, smart watches now even have functions similar to those on some smart terminals; they can also be connected to the Internet through smart terminals or home networks. For example, smart watches can provide health status monitoring (real-time monitoring of exercise, blood pressure, pulse, blood oxygen and other data), real-time sending and receiving of text messages and emails, and timely checking of mobile phone calls, providing global positioning system (GPS), real-time query of time and weather, and other functions.

[0045] Please refer to Figure 1 , is a schematic diagram of an example of a smart watch provided by an embodiment of the utility model. Figure 1 The smart watch shown includes components such as a processor 110 , a memory 120 , a transceiver 130 , a display unit 140 , an input unit 150 , a sensor 160 , an audio circuit 170 , and a power module 180 .

[0046] The processor 110 is the control center of the smart watch, and uses various interfaces and lines to connect various parts of the entire smart watch. By running or executing software programs and / or modules stored in the memory 120, and calling data stored in the memory 120, the processor 110 performs various functions of the smart watch and processes data, thereby monitoring the smart watch as a whole. Optionally, the processor 110 may include one or more processing units; optionally, the processor 110 may integrate an application processor, which mainly processes operating devices, user interfaces, and application programs, etc. Of course, other processors may also be included, which are not listed here one by one.

[0047] The memory 120 can be used to store software programs and modules. The processor 110 executes various functional applications and data processing of the smart watch by running the software programs and modules stored in the memory 120. The memory 120 may mainly include a program storage area and a data storage area, wherein the program storage area may store operating devices, applications required for at least one function (such as sound playback function, image playback function, etc.), etc.; the data storage area may store data created according to the use of the smart watch (such as audio data, phone book, etc.), etc. In addition, the memory 120 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0048] The transceiver 130 can provide wireless communication solutions for smart watches, including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc. The transceiver 130 can be one or more devices integrating at least one communication processing module, for example, integrating an antenna and a baseband processor into the transceiver 130, or integrating an antenna and a modem processor into the transceiver 130, etc., which are not limited here.

[0049] The display unit 140 may be used to display information input by the user or information provided to the user and various menus of the smart watch. The display unit 140 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc., which is not limited here.

[0050] The input unit 150 can be used to receive input digital or character information, and to generate key signal inputs related to user settings and function controls of the smart watch. Specifically, the input unit 150 can collect user operations on or near it, and drive the corresponding connection device according to a pre-set program.

[0052] The audio circuit 170 may include a speaker and a microphone, and may provide an audio interface between the user and the smart watch. The audio circuit 170 may transmit the received audio data to the speaker after converting the received audio data into an electrical signal, which is then converted into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is then received by the audio circuit 170 and converted into audio data, which is then output to the processor 110 for processing, and then sent to, for example, another smart watch through the video circuit, or the audio data is output to the memory 120 for further processing.

[0053] The smart watch also includes a power module 180 for supplying power to various components. Optionally, the power module 180 can be logically connected to the processor 110 through a power management device, so as to manage charging, discharging, power consumption and other functions through the power management device.

[0054] Although not shown, the smart watch may further include a camera. Optionally, the camera may be located in the front or rear position on the smart watch, which is not limited in the embodiment of the present invention.

[0055] It is understood that the structure illustrated in the embodiment of the present invention does not constitute a specific limitation on the smart watch. In other embodiments of the present invention, the smart watch may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0056] At present, smart watches have become the most important tool for information transmission. The antenna required for the transmission of this information is a device for receiving and transmitting signals on smart watches, and its importance is self-evident. For example, Figure 1 Antennas for transceivers in the smartwatch. In order to provide the various functions mentioned above, smartwatches need to be equipped with various antennas. For example, it is necessary to arrange multiple antennas such as cellular, GPS, BT, NFC, etc. in smartwatches. Due to the small size of smartwatches themselves and the complex structures of various circuits, there is not much space left for antennas on smartwatches. If the antenna is made only through the metal frame of the smartwatch, cellular, BT, GPS, NFC and other antennas need to be implemented on a round all-metal frame, which is undoubtedly very difficult for antenna design. Moreover, the mutual interference between these antennas is also large. In special circumstances (such as mountainous areas, wilderness, underground garages and other environments with poor signals; subway and access control card swiping, mobile phone watch remote control transmission, outdoor sports and other usage scenarios), there may be slow Internet access speed, unclear calls, serious drift of GPS tracks, poor card swiping remote control distance, etc., and the antenna of the smartwatch has poor performance problems.

[0057] In order to reduce interference between antennas and improve the antenna performance of smart watches, the utility model provides a smart watch, which can provide antennas required for various performances by combining metal accessories of the smart watch, and flexibly design various different antennas on the smart watch.

[0058] Please refer to Figure 2 , which shows a schematic diagram of the structure of a smart watch provided by an exemplary embodiment of the utility model. Figure 2 As shown in FIG. 1 , the smart watch includes: a metal watch frame 201 and a metal ornament 202. It should be noted that the above Figure 2 It is a schematic diagram of a top view looking down from the dial of a smart watch. The metal ornaments are displayed separately on one side. In actual application, according to the vertical structure of the dial, the metal ornaments are above the metal middle frame, forming an up and down structure.

[0059] The metal watch frame 201 includes a first frame 201a and a second frame 201b, and the first frame 201a and the second frame 201b are insulated from each other; the first frame 201a and the metal ornament 202 are connected by a conductor, and the first frame 201a and the metal ornament 202 form the radiator of the first antenna of the smart watch; the metal ornament 202 is insulated from the second frame 201b, and the second frame 201b forms the radiator of the second antenna of the smart watch. The conductor connected between the first frame 201a and the metal ornament 202 can be a metal conductor or a non-metal conductor, and the present solution does not limit the material of the conductor.

[0060] Optionally, the metal frame 201 is equivalent to the main frame structure of the smart watch. The dial glass and dial back cover of the smart watch can be combined with the metal frame to enclose the internal space of the smart watch. The detailed internal accessories of the smart watch are usually arranged in the internal space.

[0061] Optionally, the metal ornament 202 may be a metal ring, a metal ornament, a frame-shaped metal cover plate, etc., which is arranged on the top of the smart watch. For example, in some smart watches, the metal ring for mounting the glass above the dial and the metal frame are regarded as two parts, and the metal ring is equivalent to the metal ornament 202. Alternatively, some smart watches are provided with a personalized metal ornament above the dial, which can rotate clockwise or counterclockwise along the circumference of the dial, and the metal ornament can also be regarded as the metal ornament 202 of this solution. Alternatively, the resistant metal cover plate arranged above the dial of some smart watches is also used for decoration to increase the aesthetic appearance, and these metal ornaments can also be regarded as the metal ornament 202 of this solution.

[0062] That is to say, in the smart watch of this solution, the metal watch frame 201 is divided into a first frame 201a and a second frame 201b, the first frame 201a and the second frame 201b are insulated from each other, the first frame 201a and the metal ornament 202 are connected through a conductor as the radiator of the first antenna of the smart watch, and the second frame 201b is used as the radiator of the second antenna of the smart watch. When the first signal of the first antenna needs to be transmitted, the radiator composed of the first frame 201a and the metal ornament 202 is used as the antenna for transmission, and when the signal of the second antenna needs to be transmitted, the second frame 201b is used as the antenna for transmission. Among them, the first frame 201a and the second frame 201b are insulated from each other, and the metal ornament 202 is also insulated from the second frame 201b, which can better prevent the interference between the first antenna and the second antenna. Coupling and other situations improve the antenna performance of the smart watch.

[0063] To more clearly express the structure of the smart watch provided by this solution, please refer to Figure 3 , which shows that an exemplary embodiment of the utility model relates to Figure 2 A schematic structural diagram of a smart watch from a side view. Figure 3 is from Figure 2 From this direction, the structure of the first frame 301a and the second frame 301b included in the metal frame 301 and the metal decoration 302 is shown as follows: Figure 3 For details about the connection method, please refer to Figure 2 The description in will not be repeated here.

[0064] In summary, the smart watch provided by the utility model includes: a metal frame, the metal frame includes a first frame and a second frame, the first frame and the second frame are insulated from each other; and a metal ornament, the first frame and the metal ornament are connected by a conductor, the first frame and the metal ornament constitute the radiator of the first antenna of the smart watch; the metal ornament is insulated from the second frame, and the second frame forms the radiator of the second antenna of the smart watch. The metal frame of the smart watch includes two frames, combined with the metal ornament of the smart watch, the first frame and the metal ornament are connected by a conductor to form the radiator of the first antenna, and the second frame is used as the radiator of the second antenna, thereby providing antennas required for different performances, increasing the flexibility of designing antennas on smart watches, and improving the antenna performance of smart watches.

[0065] In a possible implementation, the above metal frame can be designed in various shapes, such as regular polygons, circles, and other structures similar to circles. In this solution, the first frame and the second frame of the metal frame are separated, and there is a gap between the two. Insulating material is added in the gap to insulate the first frame and the second frame.

[0066] Please refer to Figure 4 , which shows a schematic diagram of the structure of a smart watch provided by an exemplary embodiment of the utility model. Figure 4 As shown, the smart watch includes: a metal frame 401 and a metal decoration 402.

[0067] The metal frame 401 includes a first frame body 401a and a second frame body 401b, and the first frame body 401a and the second frame body 401b are insulated from each other; the first frame body 401a and the metal decoration 402 are connected by a conductor.

[0068] Optional, in Figure 4 In the structure shown, the first frame body 401a and the second frame body 401b are both C-shaped structures, the first end of the first frame body 401a and the first end of the second frame body 401b are arranged relative to each other to form a first break 403, and the second end of the first frame body 401a and the second end of the second frame body 401b are arranged relative to each other to form a second break 404, so that the first frame body 401a and the second frame body 401b are insulated from each other; moreover, the first frame body 401a and the second frame body 401b are also symmetrical about the plane where the first break 403 and the second break 404 are located.

[0069] It should be noted that the above Figure 4The side view is based on the 6 o'clock or 12 o'clock position of the front dial of the smart watch. In the side view, the first slit 403 and the second slit 404 can be respectively set at the positions corresponding to the 6 o'clock and 12 o'clock positions of the dial, which is equivalent to splitting the metal frame 401 from the middle, so that the metal frame 401 is divided into a first frame body 401a on the left and a second frame body 401b on the right. Figure 4 From the perspective of the first and second slits 403 and 404, the first and second slits 403 and 404 are equivalent to overlap, so the two slits are represented by slits at the same position. Of course, in actual applications, the positions of the first and second slits 403 and 404 can also be changed, such as adjusting to the positions corresponding to 7 o'clock and 1 o'clock, and the corresponding dividing boundary between the first frame and the second frame changes, but the connection method with the metal ornament does not change.

[0070] Please refer to Figure 5 , which shows that an exemplary embodiment of the utility model relates to Figure 4 A top view of a metal watch frame and metal accessories of a smart watch. Figure 5 It is equivalent to Figure 4 View the resulting view in the direction of the arrow, such as Figure 5 As shown, the first frame 501a and the second frame 501b are in a C-shaped structure. Figure 5 As described from the perspective of FIG. 5 , the shape of the metal ornament 502 can be the same as that of the metal watch frame, both of which are circular.

[0071] Optionally, in order to improve the insulation between the metal ornament 402 and the second frame 401b, and between the first frame 401a and the second frame 401b, the present invention may use insulating materials. Figure 4 In the embodiment, there is an insulating layer 405 between the metal ornament 402 and the second frame 401 b ; and the first break 403 and the second break 404 are both filled with the same insulating material as the insulating layer.

[0072] The insulating layer 405 can be made of plastic material, and the insulating layer 405 is formed by nano-injection molding plastic between the metal decoration 402 and the second frame 401b, thereby isolating the metal decoration 402 from the second frame 401b. Figure 4 In the embodiment, the insulating layer 405 is a frame-shaped structure with the same shape as the metal frame 401 and the metal decoration 402. For example, the insulating layer 405 has the same shape as the metal decoration 402 and is disposed between the metal decoration 402 and the metal frame 401 to insulate the metal decoration 402 from the second frame 401b. The first break 403 and the second break 404 are also filled with the same insulating material as the insulating layer to better insulate the first frame 401a from the second frame 401b.

[0073] In a possible implementation, the insulating layer 405 may be provided in the same shape as the half of the second frame 401b. Figure 4 In the figure, the shape of the insulating layer 405 is the same as that of the second frame 401b, and is arranged between the metal ornament 402 and the second frame 401b, and can also play the effect of insulating the metal ornament 402 and the second frame 401b. In this way, a cavity can be formed between the first frame 401a on the left and the metal ornament 402, and more circuits or other accessories can be arranged, and this solution is not limited to this.

[0074] Optionally, a metal spring is provided on the first frame 401; the metal ornament is connected to the first frame via the metal spring. Figure 5 For example, in the above Figure 5 The first frame 501a includes a metal decorative part 502 and a metal shrapnel 503. The metal shrapnel 503 is provided on the first frame 501a. The metal shrapnel 503 can be provided with a metal shrapnel. The metal decorative part 502 is connected to the first frame 501a through the metal shrapnel at the metal shrapnel 503, thereby forming a radiator of the first antenna of the smart watch. Optionally, the metal shrapnel can be a spiral shrapnel. Optionally, the metal shrapnel can be welded by a metal welding spot, or can be connected to the first frame by other movable connection methods.

[0075] In one possible implementation, the metal spring is a movable spring; the metal spring is also used to move between the first frame and the metal ornament when the first antenna is working, change the connection point between the first frame and the metal ornament, and adjust the performance of the first antenna. For example, the movable spring can rotate based on the metal welding point of the first frame to change its own contact point on the metal ornament 502, or the metal welding point of the first frame is used to weld a sliding track, and the movable spring slides based on the sliding track to change its own contact point on the metal ornament 502 and the contact point with the first frame 501a. The movement of the movable spring can be controlled by the processor of the smart watch through the relevant circuit, and the specific movement method and movement control are not limited here.

[0076] From the above content, it can be known that the first frame 401a and the metal ornament 402 in the smart watch form the radiator of the first antenna of the smart watch; the metal ornament 402 is insulated from the second frame 401b, and the second frame 401b forms the radiator of the second antenna of the smart watch. Among them, the first antenna includes any one or more of a global positioning system GPS antenna, a wireless fidelity (Wireless Fidelity, WiFi) antenna or a Bluetooth (Blue Tooth, BT) antenna, and the first frame is electrically connected to the feeding end and the grounding end of the first antenna; the first frame and the metal ornament are used to receive or send signals from the first antenna.

[0077] Optionally, the second antenna is a cellular antenna, and the second frame is used to receive or send cellular signals from the cellular antenna. The second frame is electrically connected to the feed end and the ground end of the cellular antenna; the second frame is also connected to the switch device; the switch device is used to control the switching between different frequency band circuits when the smart watch is working to cover different frequency bands supported by the cellular antenna.

[0078] Optionally, the feeding end of the second antenna is centrally symmetrical with the feeding end of the first antenna based on the center of the dial of the smart watch; and / or the grounding end of the second antenna is centrally symmetrical with the grounding end of the first antenna based on the center of the dial of the smart watch.

[0079] For example, the first antenna is a GPS / BT antenna and the second antenna is a cellular antenna. Figure 6 , which shows a schematic diagram of the internal structure of a smart watch provided by an exemplary embodiment of the utility model. Figure 6 As shown, inside the cavity contained in the metal watch frame 601, the antenna structure of the smart watch is designed as follows: a feed end 602 of the GPS / BT antenna, a ground end 603 of the GPS / BT antenna, a feed end 604 of the cellular antenna, a ground end 605 of the cellular antenna, and a switch device 606. In order to realize the antenna function of the smart watch, the first frame and the metal ornament, as the radiator of the GPS / BT antenna, need to be electrically connected to the antenna circuit.

That is, the first frame 701, the first metal lug 703 and the second metal lug 704 are a metal whole, and the second frame 702, the third metal lug 705 and the fourth metal lug 706 are a metal whole.

When the second antenna is a cellular antenna, one frame is used as the radiator of the cellular antenna, and it needs to be connected to the corresponding gaskets of the feed end and the ground end of the cellular antenna to form a complete cellular antenna structure to achieve the performance of the cellular antenna. When the first antenna is a GPS / BT / WiFi antenna, the other frame and the metal ornament are used as the radiator of the first antenna, and it needs to be connected to the corresponding gaskets of the feed end and the ground end of the GPS / BT / WiFi antenna to form a complete GPS / BT / WiFi antenna structure to achieve the performance of the GPS / BT / WiFi antenna.
