[0052] According to one specific embodiment provided by the present application, see Figure 1 and Figure 2The application discloses an antenna wiring structure of a smart wearable device, which comprises a square casing 100, a touch screen module and a main radio frequency antenna module. The square casing 100 is internally provided with a main board, the touch screen module and the main radio frequency antenna module are electrically connected with the main board, the touch screen module is arranged on the square casing 100, and the main radio frequency antenna module is arranged between the main board and the touch screen module. The touch screen module comprises a touch screen cover plate 200, the touch screen cover plate 200 is provided with cover plate wirings, the cover plate wirings are used for transmitting touch signals to a processing chip on the main board, so that normal touch control operation of the touch screen of the smart wearable device is realized. The cover plate wirings comprise a plurality of sub-wirings, the sub-wirings extend along the horizontal direction and the vertical direction, and form grid-shaped wirings on the touch screen cover plate 200. Understandably, different sub-wirings can form wirings with different lengths and positions, so that various functions of the touch screen are realized. The main radio frequency antenna module is provided with at least two first conductive parts, the first conductive parts are in contact with the cover plate wirings and are electrically connected with the cover plate wirings, and form first antenna wirings 403 for signal transmission and reception of the main radio frequency antenna module.

[0053] In the embodiment, the first conductive parts are arranged on the main radio frequency antenna module, the first conductive parts are in contact with the cover plate wirings and are electrically connected with the cover plate wirings by the contact conductivity of the first conductive parts, at this time, the cover plate wirings can be used for transmitting antenna signals in addition to transmitting touch signals, and are used as antenna wirings, so that the utilization rate of the structure is high, the antenna receiving area and the design area can be improved in the limited space, and the antenna performance is improved. Moreover, the antenna is arranged by using the original cover plate wirings of the smart wearable device, which is beneficial to realizing the lightness, miniaturization and lightness of the smart wearable device, facilitating the user to carry the smart wearable device, and improving the use comfort.

[0054] The square casing 100 can be made of plastic material, because the attenuation of plastic to electromagnetic waves is small, the signal transmission is more favorable, and the lightness requirement is met.

[0055] Further, the antenna wiring structure can further comprise a frequency conversion module which is fixedly arranged on the main board and is electrically connected with the main board. The frequency conversion module is used for switching different sub-wirings and first conductive parts, the combination of the different sub-wirings and the first conductive parts can form first antenna wirings 403 with different lengths and positions, by changing the first antenna wirings 403, the main radio frequency antenna can be more suitable for different working frequency bands of the smart wearable device, the signal transmission is more stable, so that the full-band coverage of the antenna is realized in the limited space, and the space resources are fully utilized. In addition, the switching and adjustment of the first antenna wirings 403 can effectively avoid electromagnetic coupling interference under different frequency bands, and ensure the transmission quality of the touch screen touch control signal, so that the cover plate wirings can be fully utilized without affecting the original function of the cover plate wirings, the structure is reasonable and effective.

[0056] In one embodiment, the touch screen cover plate 200 is square-shaped, matching the outline of the square-shaped casing 100. The touch screen cover plate 200 has a first side wall 210, a second side wall 220, a third side wall 230 and a fourth side wall 240 connected in sequence, and the cover plate traces thereon include five groups of longitudinal sub-traces and five groups of transverse sub-traces.

[0057] Taking the first side wall 210 and the third side wall 230 as the two ends of the touch screen cover plate 200 in the longitudinal direction, and the second side wall 220 and the fourth side wall 240 as the two ends of the touch screen in the transverse direction, for example, from the first side wall 210 to the third side wall 230, the five groups of transverse sub-traces are respectively a first transverse sub-trace group 301, a second transverse sub-trace group 302, a third transverse sub-trace group 303, a fourth transverse sub-trace group 304 and a fifth transverse sub-trace group 305. Each group of transverse sub-traces includes four transverse sub-traces, and from the second side wall 220 to the fourth side wall 240, the four transverse sub-traces are respectively a first transverse sub-trace 306, a second transverse sub-trace 307, a third transverse sub-trace 308 and a fourth transverse sub-trace 309.

[0058] Conversely, from the second side wall 220 to the fourth side wall 240, the five groups of longitudinal sub-traces are respectively a first longitudinal sub-trace group 310, a second longitudinal sub-trace group 311, a third longitudinal sub-trace group 312, a fourth longitudinal sub-trace group 313 and a fifth longitudinal sub-trace group 314. Each group of longitudinal sub-traces includes four longitudinal sub-traces, and from the first side wall 210 to the third side wall 230, the four longitudinal sub-traces are respectively a first longitudinal sub-trace 315, a second longitudinal sub-trace 316, a third longitudinal sub-trace 317 and a fourth longitudinal sub-trace 318.

[0059] Specifically, referring to Figure 1 and Figure 2 , the first conductive part includes two first ground pins 501 and a first signal pin 402, which are electrically connected to the mainboard through the flexible circuit board and located on the side of the mainboard facing the touch screen module. When the first signal pin 402 and one of the two first ground pins 501 are in contact with the cover plate traces and realize conductive connection, a first antenna trace 403 can be formed; conversely, when the first signal pin 402 and the other of the two first ground pins 501 are in contact with the cover plate traces and realize conductive connection, another first antenna trace 403 can be formed.

[0060] The two first antenna traces 403 are different in length and position, the shorter one can be used as a medium-high frequency antenna trace, and the longer one can be used as a low frequency antenna trace, so as to realize full-band coverage of the antenna of the smart wearable device and improve the overall performance of the smart watch. Moreover, the two first antenna traces 403 are coupled by one signal pin and one ground pin, and the ground can reduce the interference of the surrounding environment components on the main radio frequency antenna module, thereby improving the anti-interference performance of the antenna and ensuring the stability of the antenna performance.

[0061] Specifically, referring to Figure 2 , the first signal pin 402 is located at the region where the first side wall 210 and the second side wall 220 meet, and the two first ground pins 501 are respectively arranged on the two sides of the first signal pin 402, i.e., the two first signal pins 402 are respectively located at the edge of the first side wall 210 and the edge of the second side wall 220. By arranging the first signal pin 402 between the two first ground pins 501, the distance between the two first ground pins 501 can be increased in a limited area, the isolation degree is improved, and the signal interference between the two first antenna traces 403 is reduced.

[0062] Specifically, referring to Figure 1 and Figure 2 , the first longitudinal sub-trace 315 of the first longitudinal sub-trace group 310, the first transverse sub-trace 306 and the second transverse sub-trace 307 of the first transverse sub-trace group 301, the first longitudinal sub-trace 315 of the third longitudinal sub-trace group 312, and the first transverse sub-trace 306 and the second transverse sub-trace 307 of the second transverse sub-trace group 302 together form a first antenna trace 403 (green trace line shown in Figure 2 ), which is in contact with and electrically connected to the first signal pin 402 and the first ground pin 501 located at the edge of the first side wall 210, and can be used as a medium-high frequency antenna trace.

[0063] On the contrary, the first longitudinal sub-trace 315 and the second longitudinal sub-trace 316 of the first longitudinal sub-trace group 310, all the transverse sub-traces of the first transverse sub-trace group 301, the first longitudinal sub-trace 315 and the second longitudinal sub-trace 316 of the fifth longitudinal sub-trace group 314, and all the transverse sub-traces of the third transverse sub-trace group 303 together form another first antenna trace 403 (blue trace line shown in Figure 2 ), which is in contact with and electrically connected to the first signal pin 402 and the first ground pin 501 located at the edge of the second side wall 220, and can be used as a low frequency antenna trace.

[0064] Of course, the layout of the first antenna trace 403 is not limited to this. In some embodiments, the first longitudinal sub-trace 315 in the first longitudinal sub-trace group 310, the second longitudinal sub-trace group 311, the third longitudinal sub-trace group 312, and the fourth longitudinal sub-trace group 313, the first horizontal sub-trace 306, the second horizontal sub-trace 307 (selecting two second horizontal sub-traces 307), and the third horizontal sub-trace 308 in the first horizontal sub-trace group 301, and the first horizontal sub-trace 306 and the third horizontal sub-trace 308 in the second horizontal sub-trace group 302 can be combined to form another type of first antenna trace 403. Figure 2 The yellow trace shown in the diagram represents the first antenna trace 403, which can contact and achieve conductive connection with the first signal pin 402 and the first grounding pin 501 located at the edge of the first sidewall 210. Alternatively, the first longitudinal sub-trace 315 and the second longitudinal sub-trace 316 of the first longitudinal sub-trace group 310, all the transverse sub-traces of the first transverse sub-trace group 301, the first longitudinal sub-trace 315 of the fifth longitudinal sub-trace group 314, the second transverse sub-trace 307 and the fourth transverse sub-trace 309 of the second transverse sub-trace group 302, the second longitudinal sub-trace 316 of the second longitudinal sub-trace group 311, the third longitudinal sub-trace group 312, and the fourth longitudinal sub-trace group 313, and the first transverse sub-trace 306 and the third transverse sub-trace 308 of the third transverse sub-trace group 308, can be combined to form another type of first antenna trace 403. Figure 2 (As shown in the dark red wiring diagram), the first antenna wiring 403 can contact and achieve conductive connection with the first signal pin 402 and the first grounding pin 501 located at the edge of the second sidewall 220.

[0065] In actual production, the position of the first signal pin 402 is fixed, while the positions of the two first grounding pins 401 can be flexibly adjusted according to the actual network environment. They are not limited to the layout provided in the above embodiments, and are all within the protection scope of this application.

[0066] Furthermore, the number of first grounding pins 401 is not limited to two; an appropriate number of grounding pins can be added according to actual needs. For example, see [link to relevant documentation]. Figure 3 The main RF antenna module adds seven more first ground pins 401 to the existing two first ground pins 401. Correspondingly, it forms more optional first antenna traces 403, which is more conducive to improving antenna performance.

[0067] Optionally, the frequency switching module includes a frequency band detection unit and an antenna switch. The frequency band detection unit is used to monitor the operating frequency band of the smart wearable device and transmit the acquired operating frequency band information to the processing chip on the motherboard. The antenna switch is configured to switch different sub-traces and the first conductive part under the control of the processing chip to change the first antenna trace 403.

[0068] The embodiment sets the frequency band detection unit, so that the frequency conversion module (antenna switch) can dynamically adjust the first antenna according to the frequency band, optimizes the wireless communication performance of the smart wearable device under each frequency band, reduces electromagnetic interference under different frequency bands, and is beneficial to further improve the overall performance of the smart wearable device.

[0069] Optionally, referring to Figure 1 and Figure 2 , the antenna trace structure can further include a wireless communication antenna module that can receive and transmit global positioning system signals and wireless local area network signals. The wireless communication antenna module is provided with at least two second conductive parts, which are in contact with and electrically connected to the cover plate trace to form a second antenna trace 503 for signal transmission and reception of the wireless communication antenna module.

[0070] In the embodiment, the wireless communication antenna module also uses the cover plate trace as the antenna trace to realize signal transmission and reception of the antenna, fully utilizes the original structure of the smart wearable device, thereby improving the antenna receiving area and design area in the limited space, improving the antenna performance, making the overall structure of the smart wearable device more reasonable and effective, and having high utilization rate.

[0071] Specifically, the second conductive part includes two second grounding feet 501 and one second signal foot 502, which are electrically connected to the mainboard through the flexible circuit board and located on the side of the mainboard facing the touch screen module. When the second signal foot 502 and one of the two second grounding feet 501 are in contact with and electrically connected to the cover plate trace, a second antenna trace 503 can be formed; on the contrary, when the second signal foot 502 and the other of the two second grounding feet 501 are in contact with and electrically connected to the cover plate trace, another second antenna trace 503 can be formed.

[0072] In the embodiment, one of the two second antenna traces 503 can be used as a WIFI and Bluetooth antenna trace, and the other can be used as a GPS antenna trace. Both of the two second antenna traces 503 are coupled by a signal foot and a grounding foot, and the grounding can reduce the interference of the surrounding environmental components on the wireless communication antenna module, thereby improving the anti-interference performance of the antenna performance and ensuring the stability of the antenna performance.

[0073] Specifically, the second signal foot 502 is located in the region where the third side wall 230 and the fourth side wall 240 meet, and the two second grounding feet 501 are located at the edge of the third side wall 230, one of which is arranged close to the second side wall 220, and the other is arranged close to the fourth side wall 240.

[0074] In the embodiment, the distance between the two second grounding pins 501 is greater than the distance between the second signal pin 502 and its nearest second grounding pin 501, which can reduce the signal interference between the two second antenna traces 503. Of course, in actual production, the second signal pin 502 can also be arranged between the two second signal pins 502, which is not limited herein and is within the protection scope of the present application.
