Description

Technical Field

[0001] This application relates to the field of smart wearable device technology, and more particularly to a smartwatch and its antenna wiring structure. Background Technology

[0002] With the advent of today's digital age, smartwatches have evolved from simply telling time to include functions such as making and receiving calls, sending and receiving text messages, and connecting to mobile data networks, meeting people's daily communication needs. Whether users are exercising or busy with their hands, they can answer calls and communicate via voice, greatly enhancing the practicality and user experience of smartwatches, making them an indispensable smart device for people during exercise, travel, or busy times.

[0003] As smartwatches offer increasingly more functionality, their demands on antenna performance are also rising. To meet the diverse functionalities of smartwatches and ensure stable data transmission and communication in various network environments, equipping them with full-band antennas has become essential. However, the rapid miniaturization and thinning of smartwatches have resulted in extremely limited internal space, severely restricting antenna installation and making it difficult to cover all frequency bands. This means that in certain frequency bands, smartwatches may experience signal instability, data transmission delays, or even connection failures, impacting user experience and the device's normal functionality. Furthermore, most current smartwatches require metal frames, which can absorb antenna performance, leading to poor antenna performance.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary people skilled in the art need to solve. Utility Model Content

[0016] In some embodiments, the antenna module includes a main radio frequency antenna module, which is provided with a first conductive part, the first conductive part including a first ground pin, a second ground pin, a third ground pin and a first signal pin;

[0017] The cover plate trace has multiple transmission lines. The cover plate trace contacts the first ground pin, the second ground pin, and the first signal pin and achieves conductive connection to form the first radio frequency transmission line. The cover plate trace contacts the first ground pin, the third ground pin, and the first signal pin and achieves conductive connection to form the second radio frequency transmission line.

[0018] In some embodiments, the dial includes four equally divided sector areas, which are arranged in sequence as a first sector area, a second sector area, a third sector area, and a fourth sector area, together forming a circular dial.

[0019] The first grounding pin, the first signal pin, and the second grounding pin are all located at the edge of the first sector area and close to the fourth sector area. The first grounding pin, the first signal pin, and the second grounding pin are arranged sequentially from away from the fourth sector area toward the fourth sector area. The third grounding pin is located at the edge of the third sector area and close to the fourth sector area.

[0020] The first radio frequency transmission line is a medium-to-high frequency transmission line, and the second radio frequency transmission line is a low-frequency transmission line.

[0021] In some implementations, the antenna routing structure of the smartwatch also includes: a frequency switching module, located on the motherboard;

[0022] 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 smartwatch and transmit the acquired operating frequency band information to the processing chip on the motherboard. The antenna switch is configured to turn on or off the first radio frequency transmission line and the second radio frequency transmission line under the control of the processing chip.

[0023] In some embodiments, the antenna module further includes a wireless communication antenna module, which has a second conductive part, including a fourth ground pin, a fifth ground pin, and a second signal pin.

[0026] When the first signal transmission line is connected, the wireless communication antenna module is configured to implement WIFI and Bluetooth functions; when the second signal transmission line is connected, the wireless communication antenna module is configured to implement GPS functions.

[0027] In some implementations, the fourth grounding pin is located at the edge of the second sector area and close to the third sector area, while the fifth grounding pin and the second signal pin are located at the edge of the third sector area and close to the second sector area.

[0028] The fifth grounding pin is located between the fourth grounding pin and the second signal pin, and the distance between the fourth grounding pin and the fifth grounding pin is greater than the distance between the fifth grounding pin and the second signal pin.

[0029] This application also provides a smartwatch, including the smartwatch antenna wiring structure provided in any of the above embodiments.

[0030] The technical advantages of this application are as follows:

[0031] 1. In this application, the antenna module is provided with a conductive part. Through contact between this conductive part and the cover plate wiring, the antenna module and the cover plate wiring can be made conductive, allowing the cover plate wiring to also be used as antenna wiring, becoming a conductor for the antenna to receive and transmit signals. This makes full use of the limited internal space of the smartwatch, increasing the antenna receiving area and design area within the limited space, and improving antenna performance. At the same time, the full utilization of the cover plate wiring also makes the smartwatch thinner and lighter, which is conducive to miniaturization and lightweight production.

[0032] 2. In this application, the antenna module includes a main radio frequency antenna module, which forms a first radio frequency transmission line and a second radio frequency transmission line after contacting the cover plate wiring by setting a first ground pin, a second ground pin, a third ground pin, and a first signal pin. The first radio frequency transmission line and the second radio frequency transmission line have different lengths and can be used as mid-to-high frequency transmission lines and low-frequency transmission lines, respectively, thereby achieving full-band coverage of the smartwatch and improving the overall performance of the smartwatch. Moreover, both the first radio frequency transmission line and the second radio frequency transmission line are coupled and connected by one signal pin and two ground pins, which can reduce the interference of surrounding environmental components to the main radio frequency antenna module, thereby improving the anti-interference performance of the antenna and ensuring the stability of the antenna performance.

[0033] 3. In this application, by setting a frequency band monitoring unit, the current operating frequency band of the smartwatch can be monitored in real time, and the monitored operating frequency band information is transmitted to the processing chip on the motherboard. The processing chip can then flexibly control the antenna switch to switch between the first radio frequency transmission line and the second radio frequency transmission line for different frequency bands, thereby optimizing the wireless communication performance of the smartwatch in various frequency bands and reducing electromagnetic coupling interference in different frequency bands, significantly improving the stability and accuracy of the touch screen signal.

[0034] 4. In this application, the antenna module also includes a wireless communication antenna module, which can receive and transmit GPS signals and Wi-Fi signals. The wireless communication antenna module, by setting a fourth ground pin, a fifth ground pin, and a second signal pin, forms a first signal transmission line and a second signal transmission line after contacting the cover plate wiring. This fully utilizes the cover plate wiring of the smartwatch, increasing the antenna receiving area and design area within a limited space, improving antenna performance, and making the overall structure of the smartwatch more reasonable and effective.

[0045] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0046] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0047] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0048] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0049] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various components of this application are relative rather than absolute. These descriptions are appropriate when these components are in the positions shown in the drawings. If the descriptions of the positions of these components change, these directional indications also change accordingly.

[0051] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] According to a specific embodiment provided in this application, see [link to specific embodiment]. Figure 1 and Figure 2 A smartwatch antenna wiring structure includes a watch face 100, a touchscreen module 200, and an antenna module. The watch face 100 houses a motherboard. The touchscreen module 200 is mounted on the watch face 100 and electrically connected to the motherboard. The antenna module is also electrically connected to the motherboard and is preferably located between the motherboard and the touchscreen module 200. The touchscreen module 200 includes a touchscreen cover plate with cover plate wiring 210 for transmitting touch signals to a processing chip on the motherboard, enabling normal touch operation of the smartwatch. The antenna module has a conductive portion that can contact and conductively connect with the cover plate wiring 210. In this case, the cover plate wiring 210 also serves as a conductor for the antenna module to receive and transmit signals, enabling signal transmission and reception by the antenna module.

[0053] This embodiment incorporates a conductive part, utilizing its contact conductivity to achieve a conductive connection upon contact with the cover plate trace 210. In this case, the cover plate trace 210 can be used not only to transmit touch signals but also to transmit antenna signals, functioning as an antenna trace. This high structural utilization rate allows for increased antenna receiving area and design area within a limited space, thereby improving antenna performance. Furthermore, utilizing the existing cover plate trace 210 of the smartwatch for antenna layout facilitates the production of a thinner, smaller, and lighter smartwatch, making it more convenient for users to carry and providing greater comfort.

[0054] In actual production, the conductive part may include a metal spring, located on the side of the motherboard facing the touch screen module 200, capable of contacting the cover plate trace 210 to achieve a conductive connection; alternatively, the conductive part may also include pins, electrically connected to the motherboard via a flexible circuit board and located on the side of the motherboard facing the touch screen module 200, achieving a conductive connection after contacting the cover plate trace 210. The pins may further include signal pins and ground pins. Grounding via the ground pin can reduce electromagnetic interference and radio frequency interference, improve signal integrity, and enhance the electromagnetic compatibility of the smartwatch.

[0055] Specifically, the dial 100 is a circular dial 100, and can be made of plastic. Plastic has less attenuation of electromagnetic waves, which is more conducive to signal transmission and also meets the requirements of lightweight design. The touch screen cover is adapted to the contour of the circular dial 100, and the cover plate traces 210 on it adopt a serpentine routing, which can increase the trace length in a limited space, make full use of space, maintain signal integrity, reduce electromagnetic interference by using the tortuous shape, and improve antenna performance.

[0056] Specifically, the antenna module includes a main radio frequency antenna module, which has conductive parts. To distinguish it from the conductive parts of the wireless communication antenna module described below, the conductive parts of the main radio frequency antenna module are referred to as the first conductive parts, and the conductive parts of the wireless communication antenna module are referred to as the second conductive parts. Taking the conductive parts including pins as an example, the first conductive part includes a first ground pin 301, a second ground pin 302, a third ground pin 303, and a first signal pin 304.

[0057] See Figure 3 Understandably, the cover plate trace 210 typically contains multiple transmission lines to implement various functions of the touchscreen. Therefore, when the cover plate trace 210 contacts the aforementioned first conductive part, multiple antenna transmission lines are formed. Specifically, the cover plate trace 210 contacts and achieves conductive connection with the first ground pin 301, the second ground pin 302, and the first signal pin 304 to form a first radio frequency transmission line 305; the cover plate trace 210 contacts and achieves conductive connection with the first ground pin 301, the third ground pin 303, and the first signal pin 304 to form a second radio frequency transmission line 306.

[0058] The first RF transmission line 305 and the second RF transmission line 306 have different trace lengths. The shorter trace can be used as a mid-to-high frequency transmission line, while the longer trace can be used as a low-frequency transmission line, thereby achieving full-band coverage for the smartwatch and improving its overall performance. Furthermore, both the first RF transmission line 305 and the second RF transmission line 306 are coupled together by one signal pin and two ground pins. Grounding reduces interference from surrounding components to the main RF antenna module, thereby improving the antenna's anti-interference capability and ensuring its stability.

[0059] Specifically, see Figures 1 to 3 The dial 100 includes four equally divided sector-shaped areas, arranged clockwise as follows: a first sector 110, a second sector 120, a third sector 130, and a fourth sector 140, forming a circular dial 100. A first ground pin 301, a first signal pin 304, and a second ground pin 302 are all located at the edge of the first sector 110 and close to the fourth sector 140, arranged sequentially from away from the fourth sector 140 towards closer to it. A third ground pin 303 is located at the edge of the third sector 130 and close to the fourth sector 140. In this configuration, the first radio frequency transmission line 305 can function as a mid-to-high frequency transmission line, while the second radio frequency transmission line 306 serves as a low-frequency transmission line.

[0060] In this embodiment, the first signal pin 304 is located between the first ground pin 301 and the second ground pin 302. This increases the distance between the first ground pin 301 and the second ground pin 302 within a limited area. For example, compared to the case where the first ground pin 301, the second ground pin 302, and the first signal pin 304 are arranged sequentially, the distance between the first ground pin 301 and the second ground pin 302 is significantly greater in this embodiment. Moreover, with this arrangement, while keeping the distance between the first ground pin 301 and the second ground pin 302 constant, it is easier to increase the distance between the third ground pin 303 and other pins, thereby improving antenna performance.

[0061] Of course, in actual production, the position of the first signal pin 304 is fixed, while the positions of the first ground pin 301, the second ground pin 302, and the third ground pin 303 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.

[0062] Furthermore, the number of grounding pins is not limited to three; an appropriate number of grounding pins can be added according to actual needs. For example, see [link to relevant documentation]. Figure 4The main RF antenna module adds ten sixth grounding pins 307 to the existing three grounding pins. Correspondingly, it forms more optional RF transmission lines, which is more conducive to improving antenna performance.

[0063] As one optional embodiment, the smartwatch antenna wiring structure may further include a frequency switching module, which is located on the motherboard and 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 smartwatch and transmit the acquired operating frequency band information to the processing chip on the motherboard. The antenna switch is configured to turn on or off the first radio frequency transmission line 305 and the second radio frequency transmission line 306 under the control of the processing chip.

[0064] This embodiment enables the smartwatch to flexibly switch between the first radio frequency transmission line 305 and the second radio frequency transmission line 306 for different frequency bands by setting a frequency switching module. This optimizes the wireless communication performance of the smartwatch in various frequency bands, reduces electromagnetic coupling interference in different frequency bands, and significantly improves the stability and accuracy of the touch screen signal.

[0065] Further, see Figure 3 The antenna module also includes a wireless communication antenna module, which can receive and transmit GPS signals and WLAN signals. The wireless communication antenna module has a second conductive part. Taking the conductive part including pins as an example, the second conductive part includes a fourth ground pin 401, a fifth ground pin 402, and a second signal pin 403. The cover plate trace 210 contacts and conductively connects with the fourth ground pin 401 and the second signal pin 403, forming a first signal transmission line 404; the cover plate trace 210 contacts and conductively connects with the fifth ground pin 402 and the second signal pin 403, forming a second signal transmission line 405.

[0066] In this embodiment, the wireless communication antenna module also uses the cover plate trace 210 as the antenna trace to realize the antenna's signal transmission and reception. This makes full use of the original structure of the smartwatch, thereby increasing the antenna receiving area and design area within a limited space, improving antenna performance, and making the overall structure of the smartwatch more reasonable and effective. Moreover, both the first signal transmission line 404 and the second signal transmission line 405 are coupled together by one signal pin and one ground pin. Grounding can reduce the interference of surrounding environmental components on the wireless communication antenna module, improve the antenna's anti-interference performance, and ensure the stability of antenna performance.

[0067] Specifically, the wireless communication antenna module includes a Bluetooth antenna, a Wi-Fi antenna, and a GPS antenna. The second signal pin 403 is electrically connected to the signal terminals of the Bluetooth antenna, Wi-Fi antenna, and GPS antenna. When the first signal transmission line 405 is turned on, the wireless communication antenna module is configured to implement Wi-Fi and Bluetooth functions; when the second signal transmission line 405 is turned on, the wireless communication antenna module is configured to implement GPS functions. The turning on and off of the first and second signal transmission lines 405 can be achieved through a circuit switch control structure, which will not be elaborated upon here, but is within the scope of protection of this application.

[0068] Specifically, see Figures 1 to 3 The fourth grounding pin 401 is located at the edge of the second sector area 120 and close to the third sector area 130. The fifth grounding pin 402 and the second signal pin 403 are located at the edge of the third sector area 130 and close to the second sector area 120. The fifth grounding pin 402 is located between the fourth grounding pin 401 and the second signal pin 403, and the distance between the fourth grounding pin 401 and the fifth grounding pin 402 is greater than the distance between the fifth grounding pin 402 and the second signal pin 403, in order to reduce signal interference between the fourth grounding pin 401 and the fifth grounding pin 402. Of course, in actual production, the second signal pin 403 can also be located between the fourth grounding pin 401 and the fifth grounding pin 402 to improve the isolation between them. This is not a limitation and is within the scope of protection of this application.

[0069] Of course, in actual production, the position of the second signal pin 403 is fixed, while the positions of the fourth ground pin 401 and the fifth ground pin 402 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.

[0070] Furthermore, the number of grounding pins 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 4 In addition to the existing two grounding pins, the wireless communication antenna module has added two seventh grounding pins 406, which in turn creates more optional signal transmission lines, thus improving antenna performance.

[0071] This application also provides a smartwatch, including the smartwatch antenna wiring structure provided in any of the above embodiments.

[0072] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0073] It should be noted that the above embodiments can be freely combined as needed. The above are merely optional embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
