[0003] Current wearable devices are designed to meet the daily wearing and use needs of users, and can support users' daily communication, leisure and entertainment, sports monitoring, vital sign monitoring and other functions. However, in emergency scenarios, such as when there is no network and emergency rescue is needed, conventional wearable devices cannot communicate with the outside world and cannot meet the needs of users in emergency scenarios. Summary of the invention

[0004] The embodiments of the present application provide a wearable device, a Beidou short message sending method and related products, which can realize external communication without a network.

[0005] In the first aspect, an embodiment of the present application provides a wearable device, including an antenna radiator, a Beidou communication module and a processor; the Beidou communication module includes a satellite positioning unit and a short message unit; the satellite positioning unit is used to obtain global position positioning information through the antenna radiator under the control of the processor; the short message unit is used to multiplex the antenna radiator to send and receive Beidou short messages under the control of the processor.

[0006] In this solution, the Beidou communication module has the Beidou short message receiving and sending function, which can realize the communication between the wearable device and the Beidou short message satellite. The Beidou communication module can interact with the processor for user authentication information, short message payload information and protocol information that requires the processor to assist in processing. The short message unit and the satellite positioning unit in the Beidou communication module are both electrically connected to the antenna radiator, and the short message unit and the satellite positioning unit can share the same antenna radiator for signal transmission or signal reception (that is, the two multiplex the antenna radiator). The satellite positioning unit can receive global position positioning information from the positioning satellite through the antenna radiator. The global position positioning information is used to indicate the location of the user, and the global position positioning information can be included in the Beidou short message, and can also be used in daily application scenarios. The short message unit can receive Beidou short messages from the short message satellite in the Beidou satellite navigation system through the antenna radiator, or send Beidou short messages to the short message satellite. Beidou short messages can be used for emergency communications.

[0007] This solution integrates the Beidou short message function into wearable devices, which can communicate with the outside world in a network-free environment, thus meeting the communication needs of users in emergency scenarios. In addition, compared with dedicated Beidou terminals that are large in size, heavy in weight, inconvenient to carry, weak in human-computer interaction, and single in function, wearable devices are small in size and weight, easy to carry, and convenient in human-computer interaction. They can have rich functions such as user motion monitoring, activity monitoring, life assistance, leisure and entertainment, vital signs monitoring, and environmental monitoring, which can meet the user's usage needs in daily scenarios.

[0008] In addition, by making the satellite positioning unit and the short message unit reuse the antenna radiator, this solution can use one antenna radiator to receive or send and receive signals of different frequencies, save the structural space of the wearable device, reduce the weight of the wearable device, and simplify the structural design, thereby improving the aesthetics of the wearable device.

In this solution, the satellite positioning unit can obtain a timing signal from a positioning satellite, and the timing signal is used for clock synchronization of the short message unit. The solution of obtaining a timing signal through a satellite positioning unit is relatively mature, and it is easy to implement device stacking and circuit design of wearable devices.

In this solution, the short message unit can obtain the timing signal from the positioning satellite, and the timing signal is used for the short message unit to perform clock synchronization. The short message unit is a new type of Beidou communication module.

[0012] This solution makes it possible to not have a satellite positioning unit, thereby improving the circuit integration of the wearable device, simplifying the circuit design, saving the structural space of the wearable device, and reducing the weight of the wearable device.

[0016] In this solution, the entire antenna radiator is exposed outside the shell. The rotating shaft connects the antenna radiator and the shell, and the antenna radiator is rotated around two intersecting axes through the rotating shaft. When the antenna radiator rotates and moves away from the shell, the clearance of the antenna radiator can be increased, and the radiation aperture of the antenna radiator can be increased. In addition, the distance from the antenna radiator to the user's arm can be increased, so that the absorption of the antenna signal by the human body is reduced, and the reduction of the hand model is reduced, thereby further enhancing the antenna performance of the antenna radiator. Therefore, this solution greatly improves the antenna performance of the antenna radiator. In addition, as an appearance part of a wearable device, the design that the antenna radiator can rotate around two intersecting axes can improve the controllability and playability of the wearable device, thereby improving the user experience.

[0018] This solution can well realize the rotation of the antenna radiator around two intersecting axes by designing the specific structure of the rotating shaft and the matching mode of the rotating shaft. In addition, this solution makes the design and manufacturing (including assembly) of the product relatively simple and the product reliability is relatively high.

[0019] In an implementation of the first aspect, one end of the second rotating shaft away from the first rotating shaft is exposed in the second shaft hole, and the other end of the second rotating shaft away from the first rotating shaft has a limiting groove; the wearable device includes a limiting buckle, and the limiting buckle has a notch; the limiting buckle is snapped into the limiting groove and contacts with the area of ​​the shell around the second rotating shaft to prevent the second rotating shaft from detaching from the second shaft hole.

[0020] This solution can simplify the assembly of the rotating shaft and the housing through the design of the limiting groove and the limiting buckle, and can form a detachable connection between the rotating shaft and the housing, which is convenient for product maintenance.

[0022] This solution connects the antenna radiator to the Beidou communication module on the circuit board through the first adapter and the spring, so as to realize the electrical connection between the antenna radiator outside the shell and the Beidou radio frequency circuit inside the shell.

[0024] This solution designs the structure of the shell so that the shell can well install and support the shaft and antenna radiator, and can realize the electrical connection between the antenna radiator outside the shell and the Beidou radio frequency circuit inside the shell. This solution makes the design and manufacturing (including assembly) of the product simpler and the product reliability is higher.

[0029] In this solution, the insulating substrate is an insulator, the conductive layer is a thin layer formed by a conductor, the conductive layer is the part of the antenna radiator that sends and receives signals, and the insulating substrate serves as a carrier of the conductive layer. The conductive layer can cover only part of the surface of the insulator, or it can cover the entire surface of the insulator. Only a part of the antenna radiator is exposed outside the shell. By performing the above-mentioned antenna design, this solution can effectively utilize the structural space of the wearable device to arrange the antenna, save the structural space of the wearable device, reduce the weight of the wearable device, ensure the product appearance experience, and at the same time ensure the antenna performance.

[0030] In an implementation of the first aspect, the insulating substrate has at least two partition portions, at least the two partition portions are spaced apart from each other, and the conductive layer is divided into a number of mutually insulated conductive areas, wherein one conductive area is electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module; the wearable device includes a first communication module disposed in the shell, the first communication module is electrically connected to the processor and the remaining conductive areas; the first communication module is used to send and receive first network signals through the remaining conductive areas under the control of the processor.

[0031] In this solution, the first communication module is a wireless communication module other than the Beidou communication module. The first communication module includes but is not limited to at least one of other satellite communication modules (such as GPS communication module), mobile communication modules (2G mobile communication module, 3G mobile communication module, 4G mobile communication module, etc.), Wi-Fi module, Bluetooth module, NFC module, infrared (IR) module, etc. The communication mode that the first communication module can implement is not limited to at least one of other satellite communication, mobile communication, Wi-Fi communication, Bluetooth communication, NFC communication, infrared communication, etc. When the first communication module and the remaining conductive areas are at least two, one first communication module is electrically connected to one of the remaining conductive areas.

[0032] This solution divides the conductive layer into sections through partitions, and can construct a Beidou antenna radiator and other antenna radiators, so that the wearable device can send and receive Beidou signals and the first network signals, so that the wearable device can be used in both emergency communication scenarios and daily life scenarios, greatly improving the product performance and market competitiveness of wearable devices.

[0033] In an implementation of the first aspect, the wearable device includes a circuit board and a spring clip, both of which are located in a shell, and the spring clip is installed on the circuit board; the processor and the Beidou communication module are both arranged on the circuit board, and the spring clip is electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module; the shell has a second through-hole, and the second through-hole connects the receiving cavity and the inner side of the shell; the wearable device includes a second adapter, which is located in the second through-hole, one end of the second adapter is connected to the conductive layer in the part of the antenna radiator fixed in the receiving cavity, and the other end of the second adapter is connected to the spring clip.

[0034] This solution connects the antenna radiator to the Beidou communication module on the circuit board through the second adapter and the spring, and can realize the electrical connection between the antenna radiator partially located outside the shell and the Beidou radio frequency circuit inside the shell. In addition, this solution makes the design and manufacturing (including assembly) of the product simpler and the product reliability is higher.

In particular, the second adapter made of conductive silicone also has sealing performance, which can ensure the waterproof performance of the wearable device.

[0036] In an implementation manner of the first aspect, the insulating substrate is a non-conductive ceramic; and / or the conductive layer is a metal or a conductive ceramic.

[0037] In this solution, the material designs of the insulating substrate and the conductive layer are independent of each other. The insulating substrate made of non-conductive ceramics is relatively light, which is conducive to the lightweight wearable device. The conductive layer made of metal not only has good conductivity, but also has good appearance performance, which can ensure the appearance experience of the wearable device. The conductive layer made of conductive ceramics not only has good conductivity, but also is relatively light, which is conducive to the lightweight wearable device.

[0038] In an implementation of the first aspect, the wearable device includes a display screen, which is mounted on a shell; the antenna radiator is in a closed ring shape, and the antenna radiator surrounds the outer periphery of the display screen.

[0039] This solution makes the antenna radiator an appearance part that can surround the display screen (when the wearable device is a smart watch, the antenna radiator can serve as a bezel), so that the antenna function can be realized by using the appearance parts of the product while ensuring the product appearance experience.

[0040] In an implementation of the first aspect, the shell includes a first shell and a second shell installed on the first shell; the first shell encloses an installation space; a receiving cavity is provided in the second shell, the receiving cavity passes through the second shell and is connected to the installation space; the Beidou communication module and the processor are both located in the installation space; the wearable device includes a conductive material; the first part of the conductive material is located outside the receiving cavity and covers a partial surface of the second shell, the second part of the conductive material fills the receiving cavity and is electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module; the conductive material serves as an antenna radiator.

[0041] In this solution, the material composition of the first part and the second part of the conductive material may be the same or different. The orthographic projection area of ​​the first part on the second shell may be larger, and the orthographic projection area of ​​the second part on the second shell may be smaller, that is, the conductive material as a whole can form a "mushroom head" or "umbrella structure". The second part filling the receiving cavity means that the second part basically completely fills the receiving cavity, and the shape of the second part basically completely matches the shape of the receiving cavity. Only a part of the antenna radiator of this solution is exposed on the outer surface of the shell. By performing the above-mentioned antenna design, this solution can effectively utilize the structural space of the wearable device to arrange the antenna, save the structural space of the wearable device, reduce the weight of the wearable device, ensure the product appearance experience, and at the same time ensure the antenna performance.

[0042] In an implementation of the first aspect, the wearable device includes a display screen, which is mounted on a first shell, the display screen and a second shell cover an installation space, and the second shell surrounds the outer periphery of the display screen; the receiving cavity is located outside the display screen.

[0043] This solution enables the second shell to surround the periphery of the display screen and the antenna radiator to be located on the periphery of the display screen. This can effectively utilize the structural space of the wearable device to arrange the antenna, save the structural space of the wearable device, reduce the weight of the wearable device, ensure the product appearance experience, and at the same time ensure the antenna performance.

[0044] In an implementation of the first aspect, the second housing has an outer surface facing away from the first housing, and the receiving cavity passes through the outer surface. The receiving cavity structure of this solution is relatively simple, easy to design and manufacture, and thus helps to simplify the relevant design of the antenna.

[0045] In an implementation of the first aspect, the wearable device includes a circuit board and a spring clip, both of which are located in an installation space; the processor and the Beidou communication module are both arranged on the circuit board; the spring clip is installed on the circuit board and is electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module, and the spring clip is connected to the conductive material; the cross-sectional area of ​​the receiving cavity tends to increase from one end of the receiving cavity away from the spring clip to the end of the receiving cavity close to the spring clip.

[0046] In this solution, the cross-sectional area can be defined as follows: perpendicular to the extension direction of the receiving cavity, cross sections are made at different positions of the receiving cavity, and multiple closed cross-sectional figures are obtained, which are arranged in sequence along the extension direction, and the area of ​​each cross-sectional figure is called the cross-sectional area. "Increasing trend" can include continuous and uniform increase of each cross-sectional area, or it can include that each cross-sectional area generally increases, but there is a sudden change in value and uneven increase in some parts.

[0047] Due to structural size limitations, the area of ​​the outer surface of the second shell is relatively small. In view of this, the opening formed on the outer surface of the second shell by the receiving cavity of the second shell can be made smaller to adapt to the smaller area of ​​the outer surface. In addition, in order to increase the mechanical connection strength between the second part and the first spring sheet to ensure reliable electrical connection between the second part and the spring sheet, the opening of the receiving cavity at one end close to the installation space of the first shell can be made larger, so that the contact area between the second part of the antenna radiator and the spring sheet can be increased, thereby increasing the mechanical connection strength and electrical connection reliability between the second part and the spring sheet.

[0048] In an implementation manner of the first aspect, the first part of the conductive material is metal, and / or the second part of the conductive material is conductive ceramic; and / or the material of the second shell is non-conductive ceramic.

[0049] In this solution, the material designs of the first part, the second part and the second shell are independent of each other. The first part made of metal not only has good conductivity, which is conducive to ensuring antenna performance, but also has a good appearance texture, which is conducive to ensuring the appearance experience of the wearable device. The second part made of conductive ceramics has good conductivity, which is conducive to ensuring antenna performance, and is relatively light, which is conducive to the lightweight of the wearable device. The second shell made of non-conductive ceramics has good insulation performance, which is conducive to ensuring antenna performance, and is relatively light, which is conducive to the lightweight of the wearable device.

[0051] In this solution, a part of the antenna radiator can always be located in the receiving cavity, and the exposed end of the antenna radiator can always be located outside the shell. The antenna radiator can be similar to the retractable umbrella pole of an umbrella. In this solution, by designing a retractable antenna radiator, when the antenna radiator is extended, the effective length of the antenna radiator increases, the distance between the exposed end and the shell increases, and the distance between the exposed end and the electrical components in the shell and the user's arm increases, which is conducive to enhancing the antenna performance of the antenna radiator. In addition, this solution can effectively utilize the structural space of the wearable device to arrange the antenna, save the structural space of the wearable device, reduce the weight of the wearable device, ensure the product appearance experience, and at the same time ensure the antenna performance.

[0052] In an implementation of the first aspect, the antenna radiator includes at least two sub-radiators connected in sequence by sliding, wherein at least a portion of one sub-radiator is located in the receiving cavity.

This solution can effectively utilize the structural space of the wearable device to arrange the antenna, save the structural space of the wearable device, reduce the weight of the wearable device, ensure the product appearance experience, and at the same time ensure the antenna performance.

[0055] In an implementation of the first aspect, the wearable device includes a shell and a strap, wherein the strap is connected to the outside of the shell; the Beidou communication module and the processor are both located in the shell; and the antenna radiator is located in the strap.

[0056] In this solution, the wearable can be made of soft insulating materials, such as nylon, braided fabric, etc. The wearable can be wrapped around a part of the human body (such as a wrist) and form a detachable connection (such as a lock connection) to enable the wearable device to be worn. The antenna radiator is wrapped in the wearable material, and the antenna radiator and the wearable can form a sandwich structure. By arranging the antenna radiator in the wearable, this solution can effectively utilize the internal space of the wearable to arrange the antenna radiator, thereby saving the internal space of the host of the wearable device. In addition, by arranging the antenna radiator in the wearable, the antenna radiator is far away from the circuit board assembly of the wearable device, which can ensure the antenna performance of the antenna radiator.

[0057] In an implementation of the first aspect, the wearable device includes a circuit board, an ear axis and a spring clip; the circuit board is located in a shell, and a Beidou communication module and a processor are arranged on the circuit board; the spring clip is installed on the circuit board and is electrically connected to a satellite positioning unit and a short message unit in the Beidou communication module; the ear axis is installed on the outside of the shell; the ear axis is connected to the wearable device, and the ear axis connects the antenna radiator and the spring clip.

[0058] In this solution, the strap is connected to the shell through the ear shaft, and the strap can rotate relative to the shell. For example, when the ear shaft is fixedly connected to the shell, the strap can be rotatably connected to the ear shaft, for example, the end of the strap can wrap around the ear shaft and rotate around the ear shaft. Alternatively, when the ear shaft is rotatably connected to the shell, the strap can be fixedly connected to the ear shaft, and the strap and the ear shaft can rotate relative to the shell together. This solution connects the antenna radiator to the Beidou communication module on the circuit board through the ear shaft and the spring clip, and can achieve electrical connection between the antenna radiator and the Beidou radio frequency circuit.

[0062] This solution obtains key information from an external device through the first communication module, so that the wearable device can obtain the key information and realize the Beidou short message function without a built-in user identity module and a modem. This can simplify the design of the wearable device, reduce the size, weight and power consumption of the wearable device, improve the waterproof and dustproof level, availability and ease of use of the wearable device, and avoid the operating temperature range of the user identity module (for example, the operating temperature range of the physical SIM card in the dedicated Beidou terminal is generally above 0°C and is not resistant to low temperatures) affecting the operating temperature range of the wearable device (generally -20°C-45°C).

[0063] In an implementation of the first aspect, the wearable device includes a first communication module and a user identity identification module, and the first communication module and the user identity identification module are both electrically connected to the processor; the first communication module is used to establish a communication connection with an external device under the control of the processor, and receive a configuration document of a Beidou short message service from the external device, and the configuration document includes key information of the Beidou short message service; the processor supports the ISO7816 protocol interaction function, and the processor is used to write the configuration document to the user identity identification module; the processor is also used to control the short message unit in the Beidou communication module to send and receive Beidou short messages through an antenna radiator according to the key information in the configuration document.

[0064] In this solution, the processor supports the ISO7816 protocol interaction function. The processor can simulate a modem (the processor can be used as a "soft modem"), directly connect to the hardware electrical interface of the user identification module, and interact with the software protocol. The processor supports user identification, authentication, statistics, billing and other functions. Therefore, the wearable device does not need a built-in modem, which can save the internal space of the wearable device.

[0065] In an implementation of the first aspect, the wearable device includes a first communication module and a user identification module, the first communication module and the user identification module are both electrically connected to the processor, the first communication module supports electrical connection and software protocol interaction with the user identification module through the ISO7816 protocol, the first communication module is used to establish a communication connection with an external device under the control of the processor, and receive a configuration document of a Beidou short message service from the external device, the configuration document containing key information of the Beidou short message service; the processor is used to write the configuration document to the user identification module; the processor is also used to control the short message unit in the Beidou communication module to send and receive Beidou short messages through an antenna radiator according to the key information in the configuration document.

[0067] In this solution, user-defined information is information edited and input by the user. The user can edit the user-defined information on other external devices that are easy to input. The wearable device can receive the user-defined information from the external device through the first communication module, and send the received user-defined information in the form of a Beidou short message. This solution can overcome the defect that the wearable device has a small operating interface and is inconvenient to input, so that the user can edit the information on an external device that is easy to input, and send the information through a Beidou short message. In addition, more personalized information can be delivered to the outside world through Beidou short messages. In summary, this solution can enhance the user experience.

This can simplify the design of wearable devices, reduce the size, weight and power consumption of wearable devices, improve the waterproof and dustproof level, availability and ease of use of wearable devices, and avoid the operating temperature range of the user identity module (for example, the operating temperature range of the physical SIM card in the dedicated Beidou terminal is generally above 0°C and is not resistant to low temperatures) affecting the operating temperature range of the wearable device (generally -20°C-45°C).

[0070] In an implementation of the first aspect, the universal serial bus interface is also used to connect to an external device and receive user-defined information from the external device; the Beidou short message sent by the antenna radiator carries the user-defined information.

[0071] In this solution, user-defined information is information edited and input by the user. The user can edit the user-defined information on other external devices that are easy to input. The wearable device can receive user-defined information from the external device through the universal serial bus interface, and send the received user-defined information in the form of a Beidou short message. This solution can overcome the defect that wearable devices are inconvenient to input due to the small operating interface, so that users can edit information on external devices that are easy to input, and send the information through Beidou short messages. In addition, more personalized information can be delivered to the outside world through Beidou short messages. In summary, this solution can improve the user experience.

The human-computer interaction module includes but is not limited to a display screen, a button, a microphone, etc. The current environment may include at least one of the working state of the wearable device, the current time, the natural environment parameters of the wearable device, and the vital sign parameters of the user wearing the wearable device. The trigger condition refers to a rule built into the wearable device that can be solidified or customized and modified to trigger the Beidou short message function.

[0079] This solution triggers Beidou short messages by input signals and / or by the current environment that meets the triggering conditions. It can enable wearable devices to conduct emergency communication with the outside world through the Beidou navigation system through the mechanism of users manually sending Beidou short messages and / or automatically sending Beidou short messages.

[0080] In an implementation of the second aspect, the current environment includes at least one of a network environment, a current time, natural environment parameters and vital sign parameters, and the network environment includes the signal strength of a cellular network and / or the signal strength of a Beidou satellite network; when the current environment is a network environment, the trigger condition includes that the signal strength of the cellular network is less than a signal strength threshold for a period of time exceeding a set period, and / or that the signal strength of the Beidou satellite network is less than a signal strength threshold for a period of time exceeding a set period; when the current environment is the current time, the trigger condition includes that the current time is the set time; when the current environment is natural environment parameters and / or vital sign parameters, the trigger condition includes that the deviation of the natural environment parameters and / or vital sign parameters from the set value exceeds a threshold.

This solution can ensure that wearable devices can communicate with the outside world in an emergency in several scenarios, improving the availability of wearable devices in multiple scenarios.

[0086] In an implementation of the second aspect, controlling the short message unit in the Beidou communication module to send the Beidou short message through the antenna radiator includes: according to the sending strategy, controlling the short message unit in the Beidou communication module to send the Beidou short message through the antenna radiator; wherein the sending strategy includes: when the state indicated by the vital sign parameters, the natural environment parameters and / or the power information of the wearable device is a safe state, first caching the Beidou short message to be sent, and when it is detected that the user operates the wearable device, sending the cached Beidou short message; when the state indicated by the vital sign parameters, the natural environment parameters and / or the power information of the wearable device is an unsafe state, directly sending the Beidou short message.

[0087] This solution sends Beidou short messages according to a preset sending strategy, which can save device power when sending Beidou short messages and ensure the continuous availability of the device.

[0088] In an implementation manner of the second aspect, the Beidou short message sent by the antenna radiator carries at least one of natural environment parameters, vital sign parameters, preset information and user-defined information.

[0089] In this solution, the preset information may be information pre-built into the wearable device. Illustratively, the preset information may be an emergency description or distress message, such as sudden natural disasters, life threats, shortage of spare materials, helping other rescued objects to seek help, performing special sports or activities (such as diving, sailing, navigation, mountaineering, rock climbing, off-roading, exploration, skiing, wing suit flying, aviation driving, parachuting, etc.) and other information.

[0131] The Beidou satellite navigation system has no signal blind spots in China. When conventional communication means fail, the Beidou satellite navigation system can still be relied on to maintain contact with the outside world. The satellites in the Beidou satellite navigation system include positioning satellites and short message satellites, among which the short message satellites have the Beidou short message communication function. Beidou short message communication has attracted widespread attention and promotion because it is not restricted by time, region, terrain and weather, especially in emergency communications.

[0132] The following embodiments of the present application provide a wearable device that can communicate with Beidou short message satellites and send and receive Beidou short messages. The wearable device includes but is not limited to smart watches, electronic blood pressure monitors, smart bracelets, smart helmets, smart clothing, smart glasses, headphones, speakers, mobile Wi-Fi, bracelets, rings, watch straps, crutches, smart backpacks, anti-lost devices, finders, pet supplies, livestock supplies, etc. The wearable device hereinafter may be, for example, a smart watch.

[0133] Figure 1 FIG. 1 is a functional structure diagram of a wearable device according to an embodiment of the present application. Figure 1 As shown, the wearable device may include a Beidou communication module, an antenna radiator, other communication modules, a vital sign monitoring module, a natural environment monitoring module, a human-computer interaction module, a processor, and a power module. Among them, the Beidou communication module, other communication modules, vital sign monitoring module, natural environment monitoring module, and human-computer interaction module are all electrically connected to the processor, and the first five work according to the instructions of the processor. The antenna radiator is electrically connected to the Beidou communication module.

[0134] The Beidou communication module has the Beidou short message sending and receiving function, which can realize the communication between wearable devices and Beidou short message satellites. The Beidou communication module can interact with the processor for user authentication information, short message payload information, and protocol information that requires the processor's assistance.

[0135] In one implementation of an embodiment of the present application, the Beidou communication module may include a short message unit and a satellite positioning unit, and the two may be integrated into one module. The short message unit and the satellite positioning unit are both electrically connected to the antenna radiator, and the two may share the same antenna radiator for signal transmission or signal reception (i.e., the two multiplex the antenna radiator). The principle of the short message unit and the satellite positioning unit multiplexing the antenna radiator will be described below.

[0136] In one implementation of the embodiment of the present application, the satellite positioning unit can obtain the timing signal and global position positioning information from the positioning satellite through the antenna radiator under the control of the processor. The satellite positioning unit can also send the timing signal and global position positioning information to the short message unit. Among them, the positioning satellite includes but is not limited to the global positioning system (GPS) satellite, the Galileo satellite navigation system (Galileo Satellite Navigation System) satellite, the GLONASS (Global Navigation Satellite System, GLONASS) satellite, and the Beidou Satellite Navigation System (Beidou Navigation Satellite System, BDS) positioning satellite. The timing signal is used for clock synchronization for the short message unit. The global position positioning information can be used to locate the user's location, and the global position positioning information can be included in the Beidou short message (described below), and can also be used for daily application scenarios (such as positioning in sports pedometers). The solution of this implementation is relatively mature, and it is easy to implement device stacking and circuit design of wearable devices.

[0137] Alternatively, in another implementation of the embodiment of the present application, the satellite positioning unit can obtain global position positioning information, but does not obtain a timing signal, and the timing signal is obtained by the short message unit itself (to be described below).

[0138] The short message unit is used to multiplex the antenna radiator to obtain the clock signal from the short message satellite in the Beidou satellite navigation system under the control of the processor, and synchronize the clock with the timing signal obtained by the satellite positioning unit according to the clock signal. Alternatively, the short message unit can multiplex the antenna radiator to obtain the timing signal from the above-mentioned positioning satellite, and synchronize the clock with the timing signal obtained by itself according to the clock signal. The latter short message unit is a new type of Beidou communication module.

[0139] After completing the clock synchronization, the short message unit can send and receive Beidou short messages through the antenna radiator. In one embodiment, the Beidou short messages sent and received by the short message unit can carry the global position positioning information, and the global position positioning information can be used to locate the user's location. The main application scenarios of this embodiment are emergency communication scenarios such as active safety reporting and emergency rescue. In these scenarios, the location information needs to be included in the short message to realize its function.

[0140] In another embodiment, the Beidou short message received and sent by the short message unit may not include the global position positioning information. This embodiment is mainly to save the payload, and some Beidou messages may be selected without location information. In this embodiment, when the short message unit obtains the timing signal by itself, the satellite positioning unit may not be provided. This solution without a satellite positioning unit can improve the circuit integration of the wearable device, simplify the circuit design, save the structural space of the wearable device, and reduce the weight of the wearable device.

[0141] Illustratively, the short message unit may include a baseband circuit and a radio frequency circuit. The baseband circuit may be used for Beidou satellite capture, tracking, decoding, protocol stack, radio frequency transceiver link management, and interface adaptation with the processor. The radio frequency circuit may be used for transceiver, filtering, and amplification of radio frequency signals.

[0142] In another implementation of the embodiment of the present application, the short message unit and the satellite positioning unit are both separate modules and may not be integrated.

[0143] Other communication modules are used to enable the wearable device to communicate with external devices (such as general communication devices such as mobile phones, tablets, wearable devices, and dedicated Beidou terminals). Among them, the external device may have a user identity module that supports the Beidou short message function (which may include a physical subscriber identity module (SIM) card and an embedded SIM (Embedded-SIM, the same below). The external device can register and activate the Beidou short message service through normal channels and processes, and obtain and store the key information required for user identity identification and authentication. Other communication modules can also be used to enable wearable devices to communicate wirelessly with base stations and satellites other than Beidou satellites.

[0144] In the embodiment of the present application, the other communication modules may include at least one of the first communication module and a universal serial bus (USB) interface.

[0145] Among them, the first communication module refers to other wireless communication modules except the Beidou communication module. The first communication module includes but is not limited to at least one of other satellite communication modules (such as GPS communication module), mobile communication module (2G mobile communication module, 3G mobile communication module, 4G mobile communication module, etc.), Wi-Fi module, Bluetooth module, NFC module, infrared (IR) module, etc. The communication mode that the first communication module can implement includes but is not limited to at least one of other satellite communication, mobile communication, Wi-Fi communication, Bluetooth communication, NFC communication, infrared communication, etc.

[0146] In one embodiment, the first communication module can share the same antenna radiator with the Beidou communication module, and the first communication module is also electrically connected to the antenna radiator. The first communication module reuses the antenna radiator to send and receive the first network signal to achieve wireless communication with the external device. The first network signal is a wireless signal corresponding to the first communication module. For example, the first network signal can be at least one of other satellite signals, mobile communication signals, Wi-Fi signals, Bluetooth signals, NFC signals, and infrared signals. The principle of the first communication module and the Beidou communication module multiplexing the antenna radiator will be described below.

[0147] Alternatively, in another embodiment, the wearable device may have an antenna radiator independent of the Beidou antenna radiator and specifically used to send and receive the first network signal. The antenna radiator is electrically connected to the first communication module, and the first communication module sends and receives the first network signal through the antenna radiator to achieve wireless communication with an external device.

[0148] The USB interface can be detachably connected to the external device. When the USB interface is connected to the external device, the wearable device communicates with the external device via the USB interface, and the wearable device does not need to be configured with an antenna radiator specifically used for sending and receiving the first network signal (described below).

[0149] In the first embodiment of the present application, the processor may control the other communication module to establish a communication connection with the external device. For example, a wireless communication connection may be established with the external device through the first communication module. In an illustrative manner, a secure and reliable communication connection may be established by binding a user account with a device and pairing the devices through cloud management. Alternatively, a wired communication connection may be established with the external device through a USB interface.

[0150] After establishing the communication connection, the processor can control the other communication module to obtain and update the key information of the Beidou short message service from the external device. The processor can store the key information in the secure storage area of ​​the wearable device for ready call at any time or on demand. Among them, the secure storage area can be a storage space in the processor, or a storage space in a dedicated memory, or a storage space reused from other devices (such as a storage area of ​​an NFC chip). The process of transferring the key information can be triggered on demand or executed regularly as planned to ensure the correctness and validity of the key information. When necessary, the processor can control the Beidou communication module to send and receive Beidou short messages through the antenna radiator based on the key information in the secure storage area. As a result, the wearable device can be independent of the external device and communicate with the Beidou satellite independently based on the key information.

[0151] In addition, in implementation mode 1, the processor may also control the other communication module to establish a communication connection with the external device to obtain user-defined information from the external device, for example, by receiving the user-defined information from the external device in a wired communication or wireless communication manner. The processor may also control the Beidou communication module to send the user-defined information in the form of a Beidou short message (described below).

[0152] The solution of implementation mode 1 enables the wearable device to realize the Beidou short message function without a built-in user identity module (physical SIM card or eSIM) and a modem. In particular, when the wearable device obtains key information (and user-defined information) from an external device through a USB interface, the wearable device can also be free of the need for a built-in antenna radiator specifically used to send and receive the first network signal. This can simplify the design of the wearable device, reduce the size, weight and power consumption of the wearable device, improve the waterproof and dustproof level, availability and ease of use of the wearable device, and avoid the operating temperature range of the user identity module (for example, the operating temperature range of the physical SIM card in the dedicated Beidou terminal is generally above 0°C and is not resistant to low temperatures) affecting the operating temperature range of the wearable device (generally -20°C-45°C).

[0153] Different from the above-mentioned embodiment 1, in the embodiment 2 of the present application, the wearable device may include a first communication module and a user identity module (physical SIM card or eSIM) at the same time. The processor may control the first communication module to establish a communication connection with an external device, and receive a configuration document of the Beidou short message service from the external device, and the configuration document contains the key information of the Beidou short message service. The processor can write the configuration document into the user identity module so that the user identity module can realize functions such as user identity identification, authentication, statistics and billing. The processor can control the Beidou communication module to send and receive Beidou short messages through the antenna radiator according to the key information in the configuration document. The processor of this embodiment 2 supports the ISO 7816 protocol interaction function, and the processor can simulate a modem (the processor can be used as a "soft modem"), directly connect to the hardware electrical interface of the user identity module, and interact with the software protocol. The processor supports functions such as user identity identification, authentication, statistics, and billing. The wearable device of the second embodiment does not need a built-in modem, which can save the internal space of the wearable device.

[0154] Different from the above-mentioned embodiment one, in the embodiment three of the embodiment of the present application, the wearable device may include a first communication module and a user identity module (physical SIM card or eSIM) at the same time, wherein the first communication module may include a modem, and the modem supports electrical connection and software protocol interaction with the user identity module through the ISO 7816 protocol. The processor can control the first communication module to establish a communication connection with an external device, and receive a configuration document of the Beidou short message service from the external device, and the configuration document contains the key information of the Beidou short message service. The processor can write the configuration document into the user identity module, and according to the key information in the configuration document, control the Beidou communication module to send and receive Beidou short messages through the antenna radiator. The processor of this embodiment three can use a conventional processor without making design changes. The solution of the embodiment three is relatively mature, and the software design is also relatively easy.

[0155] In one implementation of the embodiment of the present application, the antenna radiator may be a Beidou antenna radiator. The antenna radiator is used to convert the radio frequency signal generated by the short message unit in the Beidou communication module into an electromagnetic wave signal, and radiate the electromagnetic wave signal to the Beidou satellite. The antenna radiator is also used to receive the electromagnetic wave signal from the Beidou satellite and convert it into a radio frequency signal, and transmit the radio frequency signal to the satellite positioning unit and / or the short message unit in the Beidou communication module.

[0156] In another implementation of the embodiment of the present application, the antenna radiator can be multiplexed into a Beidou antenna radiator and other antenna radiators. The antenna radiator can transmit and receive Beidou signals (including signals received by the satellite positioning unit and Beidou short message signals transmitted and received by the short message unit) and transmit and receive first network signals in a multiplexing manner. Among them, "multiplexing" includes but is not limited to time-division multiplexing of an antenna radiator through software design and / or switching circuits, and receiving Beidou signals and first network signals at different times; or frequency-division multiplexing of an antenna radiator, and receiving Beidou signals and first network signals at the same time.

[0157] The following will be combined Figure 1a , schematically illustrating a specific principle of multiplexing antenna radiators into Beidou antenna radiators and other antenna radiators, and also illustrating a specific principle of multiplexing antenna radiators for the satellite positioning unit and the short message unit in the Beidou communication module.

[0158] In an embodiment of the present application, the frequency of the signal received by the satellite positioning unit can be 1.6 GHz, the frequencies of the signals received and sent by the Bluetooth module and the Wi-Fi module can both be 2.4 GHz, the frequency of the Beidou short message signal received by the short message unit can be 2.4 GHz, and the frequency of the Beidou short message signal sent by the short message unit can be 1.6 GHz.

[0159] like Figure 1a As shown, the satellite positioning unit is electrically connected to the input end LB (which may be called the low-frequency input end) of the dual-frequency combiner through the pre-processing module. The Bluetooth module and the Wi-Fi module are electrically connected to the two movable ends (similar to the moving contacts, the same below) of the switch A (for example, it can be a two-in-one switch), and the fixed end (similar to the static contact, the same below) of the switch A can be electrically connected to the input end HB (which may be called the high-frequency input end) of the dual-frequency combiner through the pre-processing module. The output end of the dual-frequency combiner can be electrically connected to a movable end of the switch B (for example, it can be a four-in-one switch). The receiving end RX of the short message unit can be electrically connected to the other movable end of the switch B through the pre-processing module, and the transmitting end TX of the short message unit can be electrically connected to the other movable end of the switch B through the pre-processing module. The fixed end of switch B is electrically connected to the antenna radiator. Among them, the pre-processing module is used to perform pre-processing (or pre-processing) on ​​the signal, including but not limited to at least one of filtering, amplification and other processing. The dual-frequency combiner is used to combine the input signals of two frequency bands together for output.

[0160] like Figure 1a As shown, the frequency of the signal received by the satellite positioning unit (1.6GHz) is different from the frequency of the signal received and sent by the Bluetooth module / Wi-Fi module (2.4GHz). Therefore, the satellite positioning unit and the Bluetooth module / Wi-Fi module can realize frequency division multiplexing of the antenna radiator through a dual-frequency combiner, so that the satellite positioning unit and the Bluetooth module / Wi-Fi module can share the same antenna radiator to receive signals (for the satellite positioning unit) or send and receive signals (for the Bluetooth module / Wi-Fi module) at the same time. Among them, for the Bluetooth module and the Wi-Fi module, the frequencies of the signals received and sent by the two are the same, and the two can realize time division multiplexing of the antenna radiator through switch A, so that the two can share the same antenna radiator to send and receive signals at different times.

[0161] Indicative, Figure 1a The state of switch A shown can make the Bluetooth module electrically connected to the dual-frequency combiner through switch A, so that the Bluetooth module and the satellite positioning unit can realize frequency division multiplexing of the antenna radiator through the dual-frequency combiner, so that the Bluetooth module and the satellite positioning unit can share the same antenna radiator to send or receive signals at the same time. Figure 1a It is easy to understand as shown that when switch A switches the state to electrically connect the Wi-Fi module to the dual-frequency combiner, the Wi-Fi module and the satellite positioning unit can achieve frequency division multiplexing of the antenna radiator through the dual-frequency combiner, so that the Wi-Fi module and the satellite positioning unit can share the same antenna radiator to send or receive signals at the same time.

[0162] like Figure 1aAs shown, the frequencies of the signals at the receiving end RX and the transmitting end TX of the short message unit are different (for example, 2.4 GHz and 1.6 GHz respectively), and the receiving end RX or the transmitting end TX implements time division multiplexing of the antenna radiator through switch B. Schematically, Figure 1a The state of the switch B shown can make the receiving end RX electrically connected to the antenna radiator, so the short message unit can receive the Beidou short message through the antenna radiator. Figure 1a It is easy to understand as shown in the figure that when the switch B switches the state to electrically connect the transmitting end TX with the antenna radiator, the short message unit can send the Beidou short message through the antenna radiator.

[0163] Furthermore, the satellite positioning unit and the short message unit can realize time division multiplexing of the antenna radiator through switch B. For example, Figure 1a At the moment shown, the state of switch B can enable the short message unit to receive the Beidou short message through the antenna radiator, and the satellite positioning unit will not receive the signal. When switch B switches the state at a certain moment to electrically connect the satellite positioning unit to the antenna radiator, the satellite positioning unit can receive global position positioning information (or can also receive timing signals) through the antenna radiator, and the short message unit will not send or receive signals. Similarly, the first communication module as a whole also realizes time division multiplexing of the antenna radiator with the short message unit through switch B.

[0164] Understandably, Figure 1a Only the Bluetooth module and Wi-Fi module in the first communication module are shown, which is not a limitation of the embodiment of the present application. It is easy to understand that any type of first communication module is applicable to the above circuit design principle. In addition, Figure 1a The illustrated dual-frequency combiner, two-in-one switch, and four-in-one switch are all examples. It is easy to understand that suitable circuit components can be designed as needed, not limited to the above. For example, when more than two signals need to be combined, a multi-frequency combiner can be used; an all-in-one switch (such as a three-in-one switch, a five-in-one switch, etc.) can be used to connect a corresponding number of modules or ports through the all-in-one switch.

[0165] In summary, the above-mentioned time division multiplexing and frequency division multiplexing methods can be used to realize that the first communication module and the Beidou communication module share the same antenna radiator for signal transmission and reception, that is, the antenna radiator is multiplexed into the Beidou antenna radiator and other antenna radiators. Among them, the satellite positioning unit and the short message unit in the Beidou communication module can multiplex the antenna radiator by time division multiplexing, and the time division multiplexing method can adapt to the signal frequency band distribution of the satellite positioning unit and the short message unit.

[0166] In the embodiment of the present application, by making the satellite positioning unit and the short message unit in the Beidou communication module reuse the antenna radiator, one antenna radiator can be used to receive or send and receive signals of different frequencies, and the structural space of the wearable device can be saved, the weight of the wearable device can be reduced, and the structural design can be simplified to improve the aesthetics of the wearable device. Similarly, by making the first communication module and the Beidou communication module reuse the antenna radiator, the above technical effects can also be achieved.

[0167] The vital sign monitoring module is used to monitor the vital sign parameters of the wearable device user, such as at least one of blood pressure, blood flow rate, body temperature, heart rate, blood oxygen, electrocardiogram, heart and lung sounds, respiratory rate, skin water content, fall state / trembling state, etc. The vital sign monitoring module includes but is not limited to at least one of an air bag and air pump, a body temperature sensor, a photoelectric sensor (such as a photoelectric sensor that measures heart rate through photoplethysmograph (PPG)), a blood oxygen sensor, a bioimpedance sensor, an electrocardiogram sensor, a gyroscope, an acceleration sensor, etc.

[0168] The processor processes and stores the vital sign parameter information monitored by the vital sign monitoring module, and can also transmit the vital sign parameter information to the outside through the Beidou communication module and / or other communication modules. When the processor determines that the vital sign parameter has a mutation or abnormality (the mutation or abnormality can be determined based on pre-set conditions or thresholds), the processor can remind or warn the user through the human-computer interaction module. The processor can also transmit relevant information to the outside through the Beidou communication module and / or other communication modules.

[0169] In other implementations of the embodiments of the present application, the wearable device may not have a vital sign monitoring module.

[0170] The natural environment monitoring module is used to monitor the natural environment parameters of the wearable device, such as temperature, humidity, wind speed, altitude, water depth, UV intensity, ambient light intensity, CO 2 At least one of concentration, air pressure, geomagnetism, sound, etc. The natural environment monitoring module includes but is not limited to at least one of a temperature sensor, a barometer, an altimeter, an ambient light sensor, a geomagnetic sensor, a gas sensor, etc.

[0171] The processor processes and stores the natural environment parameter information monitored by the natural environment monitoring module, and can also transmit the natural environment parameter information to the outside through the Beidou communication module and / or other communication modules. When the processor determines that the natural environment parameter has a sudden change or abnormality (the sudden change or abnormality can be determined based on a pre-set condition or threshold), the processor can remind or warn the user through the human-computer interaction module. The processor can also transmit relevant information to the outside through the Beidou communication module and / or other communication modules.

[0172] In other implementations of the embodiments of the present application, the wearable device may not have a natural environment monitoring module.

[0173] The human-computer interaction module is used to work under the control of the processor to realize human-computer interaction between the user and the wearable device. For example, the human-computer interaction module may include at least one of a display screen, a button, an electroacoustic device, a vibration motor, etc. Among them, the display screen displays the picture to the user and can also respond to the user's touch operation. The button is used for the user to press, rotate and / or pull to respond to the user's operation and trigger the corresponding function, such as realizing the power on and off, realizing the operation and control of various functional items of the wearable device, etc. Electroacoustic devices include but are not limited to buzzers, speakers, microphones, etc., which are used to output audio or receive user voice. The vibration motor is used to provide vibration feedback to the user through vibration.

[0174] The power module is used to supply power to the processor, Beidou communication module, other communication modules, vital signs monitoring module, natural environment monitoring module, human-computer interaction module, etc. The power module includes a rechargeable battery.

[0175] In one implementation of an embodiment of the present application, the rechargeable battery can have a higher discharge rate (the discharge rate is the current value required for the battery to discharge its rated capacity within a specified time, represented by the letter C. For example, 1C represents the current required to discharge the battery in 1 hour, and 2C represents the current required to discharge the battery in 0.5 hours), for example, a discharge rate of up to 8.5C. The discharge current of such a rechargeable battery can be as high as about 3.5A, which can meet the power consumption requirements of wearable devices with Beidou short message function (Beidou short message function not only has high requirements on power supply power, but also has a relatively large impact on battery energy consumption and battery life. Referring to the Beidou short message service specification, wearable devices need to have a built-in high-power amplifier, and the output power of the power amplifier is about 3W-5W. Taking into account the energy conversion efficiency of the power amplifier, the power supply efficiency of the wearable device and the power consumption requirements of other parts of the wearable device, the power consumption requirement of the wearable device during the Beidou short message sending may be close to or even exceed 10W. Wearable devices generally use rechargeable lithium batteries with a minimum discharge voltage of about 3V, which means that the discharge current of the battery will be as high as about 3.5A).

[0176] In one implementation of an embodiment of the present application, the capacity and size of the rechargeable battery can be kept within a reasonable range. For example, the capacity of the rechargeable battery can be around 400mAh-450mAh, which is a large capacity and can meet the needs of the Beidou short message function. The overall size of the rechargeable battery can be roughly 27.5mm·26.25mm·5.65mm. Such a size does not affect the product size and appearance experience of the wearable device, and is also relatively light. Therefore, the capacity and size of the rechargeable battery of the embodiment of the present application can take into account the Beidou short message function and wearable requirements of the wearable device.

[0177] In other implementations of the embodiments of the present application, the rechargeable battery can be a conventional battery and does not need to have the above-mentioned discharge rate, discharge current, capacity and size design.

[0178] The specific structures of several wearable devices will be described in detail below. It can be understood that the framework structure of the wearable device described above can be applicable to any specific wearable device described below.

[0179] Embodiment 1

[0180] In the first embodiment, Figure 2 and Figure 3 As shown, the wearable device 10 may include a housing 11, a circuit board assembly 15, a display screen 14, an antenna radiator 13, a rotating shaft 12, a first adapter 16 and a limit buckle 17. Each of them will be described below.

[0181] like Figure 3 As shown, the housing 11 may be approximately in the shape of a closed ring or a cylinder, and may be used as a middle frame of a smart watch, for example. The housing 11 may be made of a non-conductive material, such as a plastic material.

[0182] like Figure 3 and Figure 4 As shown, the housing 11 may include a main body portion 111 and an ear portion 112 .

[0183] The main body 111 may be approximately in the shape of a closed ring or a cylinder, which encloses the installation space 111a. The main body 111 may be provided with a first through hole 111b, which is a through hole and connects the inside and outside of the installation space 111a.

[0184] The ear portion 112 is connected to the outer surface of the main body 111, and the ear portion 112 is similar to an "ear" provided on the main body 111. The ear portion 112 may enclose a mounting groove 112a. The mounting groove 112a may, for example, have two opposite side walls, both of which are convexly provided on the outer surface of the main body 111, and the two side walls may be respectively located on both sides of the first through hole 111b, that is, the first through hole 111b connects the mounting space 111a with the mounting groove 112a. The side of the ear portion 112 opposite to the outer surface of the main body 111 may not have a side wall, so that the ear portion 112 is approximately a C-shaped structure. An axial hole 112b (hereinafter referred to as the second axial hole 112b, to distinguish it from the first axial hole on the antenna radiator 13) is provided on the ear portion 112, and the second axial hole 112b may be a through hole, and the second axial hole 112b may be provided on the bottom wall of the mounting groove 112a.

[0185] The structure of the housing 11 described above is merely an example, and the embodiments of the present application are not limited thereto.

[0186] like Figure 3 and Figure 4 As shown, the circuit board assembly 15 and the display screen 14 are both installed in the installation space 111a of the main body 111 of the housing 11. The main body 111 and the display screen 14 can jointly surround the circuit board assembly 15, so that the circuit board assembly 15 is accommodated in the installation space 111a and cannot be seen by the user. The display screen 14 can be completely located in the installation space 111a, or a portion of the display screen 14 can be exposed outside the installation space 111a. The display surface (the surface displaying the image) of the display screen 14 can be exposed from the opening of the installation space 111a for the user to view.

[0187] In the first embodiment, the circuit board assembly 15 may include electronic devices, and may also include mechanical components that assist the electronic devices (such as positioning, bearing, heat dissipation, electromagnetic shielding, and electromagnetic interference protection). Figure 3 As shown, the circuit board assembly 15 may include a circuit board 151 and a spring 152. The spring 152 is mounted on the circuit board 151 and the spring 152 may be connected to a feed point on the circuit board 151. Figure 2 As shown, the feed point can be located between the switch B and the antenna radiator, and electrically connected to the fixed end of the switch B, that is, the feed point can be electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module (when the first communication module and the Beidou communication module reuse the antenna radiator, the feed point can also be electrically connected to the first communication module). Therefore, the spring piece 152 can be electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module (when the first communication module and the Beidou communication module reuse the antenna radiator, the spring piece 152 can also be electrically connected to the first communication module).

[0188] Apart from Figure 3In addition to the above, the circuit board assembly 15 may also include other electronic components, such as the above-mentioned processor, Beidou communication module, other communication modules, user identification module, battery, vibration motor, buzzer, speaker, microphone, storage module, vital sign monitoring module, natural environment monitoring module, etc. At least part of the electronic components in the circuit board assembly 15 can be arranged on the circuit board 151. Among them, for the solution in which only part of the electronic components are arranged on the circuit board 151 and another part of the electronic components are not arranged on the circuit board 151, the other part of the electronic components can be installed at a suitable position in the housing 11.

[0189] like Figure 6 As shown, the first transition member 16 may be in a bent shape, such as a substantially L-shaped bend. A through hole 16a may be provided on the first transition member 16, and the through hole 16a may be located at the end of the first transition member 16. The first transition member 16 may be made of a conductive material, such as a metal material.

[0190] In the first embodiment, the rotating shaft 12 is used to enable the antenna radiator 13 to rotate relative to the housing 11. Figure 7 As shown, the rotating shaft 12 may include a first rotating shaft 121 and a second rotating shaft 122. The first rotating shaft 121 may be connected to one end of the second rotating shaft 122 (at Figure 7 In the embodiment, the first rotating shaft 121 is a cylindrical structure protruding from the surface of the second rotating shaft 122. The first rotating shaft 121 and the second rotating shaft 122 can be connected as a whole.

[0191] The first rotating shaft 121 may be approximately cylindrical. There may be two first rotating shafts 121, and the two first rotating shafts 121 are respectively located on opposite sides of the second rotating shaft 122, and the center lines of the two first rotating shafts 121 may coincide. The center line of the first rotating shaft 121 may be called a first axis.

[0192] The second rotating shaft 122 may be approximately cylindrical, and the end thereof away from the first rotating shaft 121 may be approximately cylindrical, and the center line of the end of the second rotating shaft 122 may be referred to as the second axis. The second axis may intersect with the first axis, for example, the two may be orthogonal or substantially orthogonal. The end of the second rotating shaft 122 away from the first rotating shaft 121 may be provided with a limiting groove 122a, and the limiting groove 122a may be an annular groove, and the limiting groove 122a may surround the second axis.

[0193] like Figure 8 As shown, the shape of the limiting buckle 17 can be approximately a ring structure with a notch 17a. The limiting buckle 17 of this structure is easy to assemble and disassemble.

[0194] like Fig. 9 As shown, the antenna radiator 13 may be approximately in the shape of a closed ring, which may be used as a bezel of a smart watch. The antenna radiator 13 may be made of a conductive material, such as a metal material.

[0195] The antenna radiator 13 may include a frame 131 and a connecting portion 132, which may be connected as a whole. In one embodiment, the frame 131 may be substantially in the shape of a closed circular ring, which encloses a closed circular area. In another embodiment, the frame 131 may also be approximately in the shape of an open ring, which encloses an open area. The connecting portion 132 is located outside the frame 131. A first axial hole 132a may be provided on the connecting portion 132, and the first axial hole 132a may be a through hole, and the number of the first axial holes 132a may be two.

[0196] The above describes the structures of the various components in the wearable device 10 one by one. The following will describe the assembly design of the above components.

[0197] Fig.10 , Fig.11 , Fig.12 and Fig.13 The assembly structure of the housing 11, the first adapter 16, the rotating shaft 12, the limit buckle 17 and the antenna radiator 13 in the wearable device 10 is shown, wherein Fig.11 yes Fig.10 A partial enlarged schematic diagram of point B in the middle. Fig.13 yes Fig.12 Schematic diagram of the local enlarged structure at point C in the middle.

[0198] Combination Fig.11 and Figure 5 As shown, the first adapter 16 can be inserted into the first through hole 111b of the main body 111 of the housing 11. One end of the first adapter 16 can extend into the installation space 111a of the housing 11 and connect with the spring 152. The other end of the first adapter 16 can be located in the installation groove 112a of the ear portion 112 of the housing 11, and the other end can contact the bottom wall of the installation groove 112a.

[0199] Combination Fig.11 , Figure 6 and Figure 5 As shown, the second rotating shaft 122 of the rotating shaft 12 can pass through the through hole 16a on the first adapter 16 and the second shaft hole 112b of the ear portion 112 to be installed on the ear portion 112, and the second rotating shaft 122 contacts the first adapter 16. In addition, the second rotating shaft 122 forms a rotational fit with the through hole 16a and the second shaft hole 112b, so that the second rotating shaft 122 can rotate relative to the housing 11 around the second axis.

[0200] Combination Fig.13 , Figure 5 and Figure 7As shown, the second rotating shaft 122 of the rotating shaft 12 can extend outside the second shaft hole 112b, and the limiting groove 122a on the second rotating shaft 122 can be exposed from the second shaft hole 112b. The limiting buckle 17 is inserted into the limiting groove 122a, and the limiting buckle 17 is clamped with the groove wall of the limiting groove 122a. Due to the structure of the limiting buckle 17, the limiting buckle 17 can form a detachable connection with the limiting groove 122a. The limiting buckle 17 also contacts the ear 112, thereby preventing the second rotating shaft 122 from being separated from the second shaft hole 112b.

[0201] Combination Fig.13 and Fig. 9 As shown, the first shaft hole 132a on the connecting portion 132 of the antenna radiator 13 can be rotatably matched with the first rotating shaft 121, so that the antenna radiator 13 can rotate around the first rotating shaft 121. In addition, the antenna radiator 13 can be electrically connected to the circuit board 151 through the rotating shaft 12, the first adapter 16 and the spring 152, so that the antenna radiator 13 can be electrically connected to the Beidou communication module, so that the antenna radiator 13 can receive and send Beidou short messages.

[0202] The wearable device 10 of the first embodiment is integrated with the Beidou short message function, and can communicate with the outside in a network-free environment, thereby meeting the communication needs of users in emergency scenarios. In addition, compared with the dedicated Beidou terminal with large size, large weight, inconvenient to carry, weak human-computer interaction ability, and single function, the wearable device 10 has a small size and weight, is easy to carry, and has convenient human-computer interaction (for example, the display screen 14, buttons, motors, buzzers, speakers, microphones and other components of the wearable device 10 support users to operate, control, prompt, feedback, select, confirm, and query information of various functions of the wearable device 10), and can have rich functions such as user motion monitoring, activity monitoring, life assistance, leisure and entertainment, vital signs monitoring, and environmental monitoring, which can meet the user's usage needs in daily scenarios.

[0203] It is easy to understand from the above description that when the antenna radiator 13 is subjected to force, it can rotate relative to the housing 11 around the first axis through the rotating shaft 12, or around the second axis through the rotating shaft 12. For example, Fig.10 The diagram shows a state where the antenna radiator 13 rotates to a certain position relative to the housing 11 around the first axis. Fig.14 The diagram shows the state when the antenna radiator 13 rotates to a certain position around the second axis relative to the housing 11. In the first embodiment, the antenna radiator 13 may be rotated around the first axis first, and then around the second axis.

[0204] like Figure 2As shown, the antenna radiator 13 can be rotated to a closed position. In the closed position, the frame 131 of the antenna radiator 13 is closed with the housing 11, and the frame 131 surrounds the display screen 14. The frame 131 may not overlap with the display screen 14 at all, or may cover at least a portion of the periphery of the display screen 14.

[0205] In the first embodiment, both the circuit board assembly 15 and the display screen 14 can generate electromagnetic interference to the antenna signal. Since the antenna radiator 13 can rotate around the first axis and move away from the circuit board assembly 15 and the display screen 14, the clearance of the antenna radiator 13 is increased, and the radiation aperture of the antenna radiator 13 is increased. In addition, when the antenna radiator 13 rotates around the first axis from the closed position, the distance from the antenna radiator 13 to the user's arm increases, so that the absorption of the antenna signal by the human body is reduced, and the reduction of the hand model is reduced, thereby further enhancing the antenna performance of the antenna radiator 13. In addition, since the antenna radiator 13 can rotate around the second axis, the radiation aperture of the antenna radiator 13 is increased. Therefore, the scheme of the first embodiment greatly improves the antenna performance of the antenna radiator 13.

[0206] In addition, as an appearance part of the wearable device 10, the design of the antenna radiator 13 being able to rotate around two intersecting axes can improve the controllability and playability of the wearable device 10, thereby improving the user experience.

[0207] In the first embodiment, the display screen 14 of the wearable device 10 can display a corresponding user interaction interface to facilitate the user to use the Beidou short message function.

[0208] For example, the three satellites of the Beidou satellite navigation system are deployed in the geosynchronous orbit (GEO). When the user uses the Beidou short message function of the wearable device 10, the user needs to align the wearable device 10 roughly with the position of the Beidou GEO satellite and fine-tune the attitude of the wearable device 10 (such as the inclination relative to the equatorial plane) as needed to obtain the ideal Beidou satellite signal. In response to this, the wearable device 10 can display the following Fig.15 The user interaction interface shown. When the user uses the Beidou short message function (for example, the user can trigger the Beidou short message function by flipping the antenna radiator 13), the user interaction interface can display the compass (the signal can be sensed by the geomagnetic sensor) and the Beidou satellite signal strength information. Based on the prompts of this interface, the user can first quickly and roughly align the Beidou GEO satellite according to the direction of the compass, and then adjust the hand posture / the posture of the wearable device 10, combined with the real-time refreshed Beidou satellite signal strength, determine the appropriate hand posture / the posture of the wearable device 10, and start using the Beidou short message function.

[0209] The wearable device 10 can also display Fig.16The user interaction interface shown. Among them, the user can enter the user interaction interface through the system's Beidou short message shortcut entrance, or long press the crown, or select "Beidou short message" in the system's "Settings" option. The user interaction interface centrally and concisely presents various sub-item functions related to the short message function. These sub-item functions include but are not limited to Beidou signals, key management, location reporting, one-key alarm, one-key help, message sending, message checking, etc.

[0210] like Fig.17 and Fig.18 In the user interaction interface shown, the wearable device 10 supports timely feedback of the success or failure of the Beidou short message after sending. When the sending fails, the wearable device 10 supports options such as resend immediately, try again later, and ignore.

[0211] Embodiment 2

[0212] like Fig.19 and Fig. 20 As shown, the second embodiment provides a wearable device 20, which may include a housing 21, a circuit board assembly 24, a display screen 23, an antenna radiator 22, a second adapter 25, etc. Among them, the circuit board assembly 24 may be the same as the circuit board assembly 15 of the first embodiment, and the circuit board assembly 24 includes a circuit board 241 and a spring 242 mounted on the circuit board 241. The display screen 23 may be the same as the display screen 14 of the first embodiment.

[0213] The difference between the second embodiment and the first embodiment lies in the housing 21 , the antenna radiator 22 and the second adapter 25 . The housing 21 , the antenna radiator 22 and the second adapter 25 will be described in detail below.

[0214] like Fig. 20 As shown, the housing 21 may be in the shape of a closed ring or a cylinder, which encloses an installation space 21 a. The circuit board assembly 24 may be installed in the installation space 21 a. The display screen 23 is installed on the housing 21 .

[0215] like Fig. 20 , Fig.21 and Fig. 22 As shown, a receiving cavity 21d may be provided at one end of the housing 21 facing the display screen 14, and the receiving cavity 21d may form an opening 21c on an axial surface of the housing 21 (the normal line of the axial surface may be in the same direction as the center line of the annular housing 21). The receiving cavity 21d may surround the outer circumference of the display screen 23. The receiving cavity 21d is used to install the antenna radiator 22.

[0216] like Fig. 22 As shown, a second through hole 21 b is formed on the inner wall of the installation space 21 a of the housing 21 , and the second through hole 21 b communicates with the receiving cavity 21 d and the installation space 21 a .

[0217] like Fig.23 As shown, the antenna radiator 22 may be in the shape of a closed ring, which may be used as a bezel of a smart watch. In other embodiments, the antenna radiator 22 may also be an open ring structure, which encloses an open area.

[0218] like Fig.23 As shown, the antenna radiator 22 may include an insulating substrate 221 , and a conductive layer 222 covering the surface of the insulating substrate 221 (the conductive layer 222 is indicated by hatching).

[0219] like Fig.23 As shown, the insulating substrate 221 may include a horizontal region 221b and an inclined region 221c. The horizontal region 221b may be Fig.23 The insulating substrate 221 is surrounded by a circular ring structure in the horizontal plane in the viewing angle. The inclined area 221c can surround the horizontal area 221b and be inclined toward the outside of the horizontal area 221b. The insulating substrate 221 can have a partition portion 221a (which can be a part of the horizontal area 221b), and the shape of the partition portion 221a is not limited, and the number can be at least two. The insulating substrate 221 is made of insulating material, for example, it can be non-conductive ceramic. The insulating substrate 221 made of non-conductive ceramic is relatively light, which is conducive to the lightweight of the wearable device 20.

[0220] The conductive layer 222 may be a metal film, and the conductive layer 222 may be formed on the insulating substrate 221 by a coating process. Alternatively, the conductive layer 222 may be a metal layer, and the conductive layer 222 may be assembled on the insulating substrate 221, for example, by bonding or inlaying. Alternatively, the conductive layer 222 may be a conductive ceramic, and may be formed on the surface of a non-conductive ceramic (i.e., the insulating substrate 221) by an integrated sintering process.

[0221] like Fig.23 As shown, the conductive layer 222 may be distributed in most of the horizontal region 221b and a small portion of the inclined region 221c of the insulating substrate 221. The conductive layer 222 is divided into a plurality of mutually insulated conductive regions by the partition portion 221a. Fig.23 As shown, the conductive layer 222 is divided into a conductive region 222a and a conductive region 222b by two partition portions 221a. Fig.23 The number of conductive regions shown is only a schematic representation. According to the specific structure of the insulating substrate 221 and the number and distribution of the partitions 221 a, the conductive layer 222 may be divided into at least two conductive regions by the partitions 221 a.

[0222] In the second embodiment, each conductive area can be used to send and receive an antenna signal. For example, each conductive area can send and receive a first network signal such as a GPS signal, a mobile communication signal, a Bluetooth signal, a WiFi signal, an NFC signal, and a Beidou signal.

[0223] In other embodiments, the insulating substrate may not have a partition, and the conductive layer on the insulating substrate is continuously distributed and serves as a conductive area as a whole. The conductive layer can be multiplexed into multiple antenna radiators, and can receive and send multiple antenna signals. For example, the conductive layer can be time-division multiplexed through software design and / or switching circuits to receive and send Beidou signals and the first network signal at different times; or the conductive layer can be frequency-division multiplexed to receive and send Beidou signals and the first network signal at the same time.

[0224] The second adapter 25 has a conductive property, for example, it can be made of conductive silicone, and the second adapter 25 made of conductive silicone can also have a sealing property. Alternatively, the second adapter 25 can also be other conductive components, such as metal springs or cables.

[0225] like Fig.24 , Fig.25 and Fig. 22 As shown, the second adapter 25 can be inserted into the second through hole 21b of the housing 21, and one end of the second adapter 25 can extend into the receiving cavity 21d of the housing 21, and the other end can extend into the installation space 21a. The end of the second adapter 25 located in the installation space 21a can be connected to the spring 242 on the circuit board 241.

[0226] Combination Fig.25 and Fig. 22 As shown, one end of the inclined region 221c of the antenna radiator 22 away from the horizontal region 221b may be located in the receiving cavity 21d, and the rest of the antenna radiator 22 may be located outside the receiving cavity 21d and surround the periphery of the display screen 23. The horizontal region 221b may cover the peripheral region of the display screen 23.

[0227] like Fig.25 As shown, the portion of the antenna radiator 22 located in the receiving cavity 21d can contact the second adapter 25, and the surface of the portion of the antenna radiator 22 located in the receiving cavity 21d is a conductive layer 222. Thus, the antenna radiator 22 can be electrically connected to the circuit board 241 through the conductive layer 222, the second adapter 25 and the spring 242, thereby being electrically connected to the Beidou communication module, so that the antenna radiator 22 can receive and send Beidou short messages.

[0228] The wearable device 20 of the second embodiment can meet the communication needs of the user in emergency scenarios, and can also meet the usage needs of the user in daily scenarios.

[0229] In the second embodiment, the antenna radiator 22 can also be used as an appearance component of the wearable device 20. Therefore, the solution of the second embodiment can combine the antenna radiator and the appearance component into one, so that the appearance of the wearable device 20 is complete and beautiful.

[0230] Embodiment 3

[0231] like Fig.26 As shown, embodiment three provides a wearable device 30, which may include a first shell 33, a second shell 32, a display screen 38, a first antenna radiator 31, a second antenna radiator 37, a first spring 34, a second spring 36 and a circuit board 35.

[0232] The first housing 33 may correspond to the housing 11 or the housing 21 described above. The first housing 33 may be approximately in the shape of a closed ring or a cylinder, for example, it may be used as a middle frame or a front shell of a smart watch. The first housing 33 encloses an installation space 33a. The first housing 33 may be made of a non-conductive material, such as a plastic material.

[0233] The circuit board 35, the first spring clip 34 and the second spring clip 36 are all installed in the installation space 33a. One end of the first spring clip 34 and the second spring clip 36 are connected to different feed points on the circuit board 35. The first spring clip 34 can be electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module on the circuit board 35, and the second spring clip 36 can be electrically connected to the first communication module on the circuit board 35. The first spring clip 34 and the second spring clip 36 are distributed on the circuit board 35 at intervals.

[0234] The display screen 38 may correspond to the display screen 14 or the display screen 23 . The display screen 38 is mounted on the first housing 33 .

[0235] The second housing 32 can be installed on the first housing 33, for example, installed at an opening of the installation space 33a of the first housing 33. The second housing 32 surrounds the outer periphery of the display screen 38. Thus, the second housing 32 and the display screen 38 cover the opening of the installation space 33a, and the circuit board 35, the first elastic sheet 34 and the second elastic sheet 36 are all accommodated in the installation space 33a and cannot be seen by the user.

[0236] In one embodiment, the second housing 32 may cover the peripheral area of ​​the display screen 38. In another embodiment, the second housing 32 may not overlap the display screen 38 at all. The second housing 32 may be approximately in the shape of a closed ring or a cylinder. The second housing 32 may serve as a bezel of a smart watch. The second housing 32 may be made of an insulating material, such as non-conductive ceramic. The second housing 32 made of non-conductive ceramic is relatively light and has a better appearance and texture.

[0237] like Fig.26As shown, a receiving cavity 32a and a receiving cavity 32b may be provided on the second shell 32 . Both the receiving cavity 32a and the receiving cavity 32b may pass through the second shell 32 and communicate with the installation space 33a . Fig.26 Only two receiving cavities, namely, receiving cavity 32a and receiving cavity 32b, are shown, which is just an example. In fact, the number of receiving cavities can be any number, or at least one, as required. The structural design and matching design of each receiving cavity are basically the same, so the receiving cavity 32a will be taken as an example for description below.

[0238] like Fig.26 As shown, schematically, the receiving cavity 32a can be approximately an elongated channel or through hole (whose length is much larger than the diameter, which can be called a conductive microhole), and the receiving cavity 32a can extend approximately along the thickness direction of the circuit board 35. One end of the receiving cavity 32a can pass through the outer surface 32c of the second shell 32 that faces away from the circuit board 35. The other opposite end of the receiving cavity 32a can form an opening on the surface of the second shell 32 on the side facing the installation space 33a (that is, the inner side of the second shell 32), and the receiving cavity 32a is connected to the installation space 33a through the opening. This makes it easy for the first spring piece 34 to pass through the opening and contact the first antenna radiator 31 in the receiving cavity 32a (to be explained below). The receiving cavity 32a may or may not pass through the surface 32d of the second shell 32 facing the circuit board 35 ( Fig.26 , which is shown as a through-hole), wherein the surface 32d can contact the corresponding surface of the first shell 33.

[0239] and Fig.26 Different from the embodiment shown, in another embodiment, the other end of the receiving cavity 32a may not form an opening on the inner side surface of the second housing 32, but may penetrate the surface 32d of the second housing 32 facing the circuit board 35, and form an opening on the outer surface 32c. Schematically, the surface 32d of the second housing 32 may have a gap with the corresponding surface of the first housing 33, so that the first elastic sheet 34 penetrates the gap and contacts the first antenna radiator 31 in the receiving cavity 32a (the first antenna radiator 31 will be described below as being located in the receiving cavity 32a).

[0240] exist Fig.26 In the illustrated embodiment, the cross-sectional area of ​​the receiving cavity 32a may increase from the end of the receiving cavity 32a away from the circuit board 35 to the end of the receiving cavity 32a close to the circuit board 35 (or from the outer surface 32c to the surface 32d).

[0241] The definition of the cross-sectional area may be: perpendicular to the extension direction of the receiving cavity 32a, cross sections of the receiving cavity 32a at different positions are made to obtain a plurality of closed cross-sectional figures arranged in sequence along the extension direction, and the area of ​​each cross-sectional figure is called the cross-sectional area. Fig.26 As shown, the extension direction may be the thickness direction of the circuit board 35 , and the cross-sectional area is the area of ​​the cross-sectional figure of the receiving cavity 32 a perpendicular to the thickness direction.

[0242] Here, "increasing trend" can include continuous and uniform increase in the area of ​​each section, or it can include that the area of ​​each section generally increases, but there are sudden changes in values ​​and uneven increase in some parts. Fig.26 It is indicated that the cross-sectional area of ​​the receiving cavity 32a increases continuously and evenly, and the receiving cavity 32a may be in a trapezoidal shape that is smaller at the top and larger at the bottom.

[0243] In other embodiments, as needed, the receiving cavity 32a may not need to have the above-mentioned design of increasing cross-sectional area. For example, each position of the receiving cavity 32a may have the same cross-sectional area.

[0244] like Fig.26 As shown, the first antenna radiator 31 may include a first portion 31a and a second portion 31b, and the first portion 31a and the second portion 31b may be connected as one. The first portion 31a may cover a partial area of ​​the outer surface 32c of the second shell 32 and be located outside the receiving cavity 32a of the second shell 32. The second portion 31b may be located in the receiving cavity 32a and may substantially fill the receiving cavity 32a. The shape of the second portion 31b matches the shape of the receiving cavity 32a, for example, the second portion 31b may be a trapezoidal shape with a small top and a large bottom.

[0245] Schematically, the first part 31a can be made of a metal material, for example, the first part 31a can be formed on the outer surface 32c of the second shell 32 by an electroplating process. The first part 31a is located on the outer surface of the wearable device 30, and the first part 31a made of a metal material has a good appearance and good wear resistance. Schematically, the material of the second part 31b can be a conductive ceramic, for example, the second part 31b can be formed in the receiving cavity 32a of the second shell 32 by an integrated sintering process.

[0246] It is understandable that the materials of the first part 31a and the second part 31b can be different or the same. Moreover, the materials and molding processes of the two are not limited to those described above.

[0247] like Fig.26 As shown, one end of the first elastic piece 34 can contact the second part 31b of the first antenna radiator 31 from the end opening of the accommodating cavity 32a close to the surface 32d. Thus, the first antenna radiator 31 is electrically connected to the Beidou communication module on the circuit board 35 through the first elastic piece 34, so that the first antenna radiator 31 can receive and send Beidou short messages.

[0248] In the third embodiment, due to the limitation of the structural size, the outer surface 32c of the second shell 32 has a smaller area. In view of this, the opening formed by the receiving cavity 32a of the second shell 32 on the outer surface 32c of the second shell 32 can be made smaller to adapt to the smaller area of ​​the outer surface 32c.

[0249] In addition, in order to increase the mechanical connection strength between the second part 31b and the first elastic sheet 34 and ensure reliable electrical connection between the second part 31b and the first elastic sheet 34, the opening of the receiving cavity 32a at one end close to the installation space 33a of the first shell 33 can be made larger, so that the contact area between the second part 31b of the first antenna radiator 31 and the first elastic sheet 34 can be increased, thereby increasing the mechanical connection strength and electrical connection reliability between the second part 31b and the first elastic sheet 34. In order to intuitively illustrate the principle, Fig.26 In the figure, two dotted lines are shown in the receiving cavity 32a, which represent a circular hole with the diameter of the smaller end of the receiving cavity 32a as the diameter. It is easy to see that the inner wall of the receiving cavity 32a is inclined compared to the inner wall of the circular hole, so the area of ​​the second part 31b that contacts the first elastic sheet 34 is larger.

[0250] like Fig.26 As shown, the design of the second antenna radiator 37 can be basically consistent with the design of the first antenna radiator 31. For example, a portion of the second antenna radiator 37 can be filled in the receiving cavity 32b, and another portion of the second antenna radiator 37 covers a partial surface of the second shell 32 and is located outside the receiving cavity 32b. The second antenna radiator 37 can be electrically connected to the first communication module on the circuit board 35 through the second spring 36, so that the second antenna radiator 37 can receive and send the first network signal.

[0251] The wearable device 30 of the third embodiment can meet the communication needs of the user in emergency scenarios and the usage needs of the user in daily scenarios. In addition, the antenna radiator in the wearable device 30 can also be used as the appearance part of the wearable device 30. By combining the antenna radiator and the appearance part into one, the appearance of the wearable device 30 can be made complete and beautiful.

[0252] Embodiment 4

[0253] like Fig. 27 and Fig.28 As shown, embodiment 4 provides a wearable device 40, which may include a shell 41, an antenna radiator 42, a display screen 43, a spring, a circuit board, a processor, a Beidou communication module, other communication modules, and the like.

[0254] The structure of the housing 41 is not specifically limited, for example, it can be basically the same as the housing 21 described above, and is also approximately a closed ring structure. The housing 41 is also provided with a receiving cavity for installing the antenna radiator 42, and the receiving cavity passes through the housing 41 to connect the outside with the installation space of the housing 41.

[0255] The display screen 43 is mounted on the housing 41, and the shrapnel, circuit board, processor, Beidou communication module, other communication modules, etc. of the wearable device 40 are accommodated in the installation space of the housing 41, so that the user cannot directly see them. The display screen 43 has a display plane, which is the plane of the display screen 43 facing the outside of the wearable device 40, that is, the plane that the user can observe.

[0256] Different from the above-mentioned shell 21 , the receiving cavity on the shell 41 can be opened on the peripheral side surface of the shell 41 (the normal line of the peripheral side surface is along the radial direction of the shell 41 ).

[0257] The antenna radiator 42 includes a receiving end and an exposed end 425a opposite to each other, and the receiving end and the exposed end 425a are two parts of the antenna radiator 42. The receiving end of the antenna radiator 42 is located in the receiving cavity and connected to the spring, and the exposed end 425a of the antenna radiator 42 is located outside the receiving cavity.

[0258] Different from the above-mentioned antenna radiator, the antenna radiator 42 can be installed on the side of the housing 41, and the antenna radiator 42 is a retractable component. Schematically, the antenna radiator 42 can be retracted in a direction parallel to the display plane of the display screen 43, or in other words, the antenna radiator 42 can be retracted in the radial direction of the housing 41. When the antenna radiator 42 is extended (such as Fig.28 As shown), the distance between the exposed end 425a and the receiving end increases (that is, the distance from the housing 41 increases); when the antenna radiator 42 is shortened (as shown Fig. 27 As shown in FIG. 4 , the distance between the exposed end 425a and the receiving end is reduced (ie, the distance between the exposed end 425a and the housing 41 is reduced).

[0259] like Fig.28As described above, schematically, the antenna radiator 42 may be formed by connecting several segments of sub-radiators in sequence, and each two adjacent segments of sub-radiators are slidably connected. For example, the antenna radiator 42 may include five segments of sub-radiators, namely, a first sub-radiator 421, a second sub-radiator 422, a third sub-radiator 423, a fourth sub-radiator 424, and a fifth sub-radiator 425, which are connected in sequence. The first sub-radiator 421 is slidably connected to the second sub-radiator 422, the second sub-radiator 422 is slidably connected to the third sub-radiator 423, the third sub-radiator 423 is slidably connected to the fourth sub-radiator 424, and the fourth sub-radiator 424 is slidably connected to the fifth sub-radiator 425. It can be understood that the number of sub-radiator segments of the antenna radiator 42 can be designed as needed, and is not limited to the five segments mentioned above, for example, at least two segments.

[0260] The end of the first sub-radiator 421 away from the second sub-radiator 422 is located in the receiving cavity of the shell 41, and this end of the first sub-radiator 421 can be referred to as the above-mentioned receiving end. The first sub-radiator 421 can be movably connected to the receiving cavity of the shell 41, and the first sub-radiator 421 can move along the radial direction of the receiving cavity (such as Fig. 27 and Fig.28 As shown), or the first sub-radiator 421 is fixed in the receiving cavity. For the above two designs of the first sub-radiator 421, the receiving end of the first sub-radiator 421 can always be located in the receiving cavity.

[0261] The second sub-radiator 422, the third sub-radiator 423, the fourth sub-radiator 424 and the fifth sub-radiator 425 can all move along the radial direction of the receiving cavity. The end of the fifth sub-radiator 425 away from the first sub-radiator 421 can be called the exposed end 425a mentioned above, and the exposed end 425a is always located outside the receiving cavity and also outside the housing 41. The size (e.g., diameter) of the exposed end 425a can be relatively large, so that the user can apply force to lengthen or shorten the antenna radiator 42.

[0262] Schematically, the first sub-radiator 421, the second sub-radiator 422, the third sub-radiator 423, the fourth sub-radiator 424 and the fifth sub-radiator 425 can all be cylindrical structures. The first sub-radiator 421 is located at the periphery of the second sub-radiator 422, and the inner wall of the first sub-radiator 421 can be slidably connected to the outer wall of the second sub-radiator 422; the second sub-radiator 422 is located at the periphery of the third sub-radiator 423, and the inner wall of the second sub-radiator 422 can be slidably connected to the outer wall of the third sub-radiator 423; the third sub-radiator 423 is located at the periphery of the fourth sub-radiator 424, and the inner wall of the third sub-radiator 423 can be slidably connected to the outer wall of the fourth sub-radiator 424; the fourth sub-radiator 424 is located at the periphery of the fifth sub-radiator 425, and the inner wall of the fourth sub-radiator 424 can be slidably connected to the outer wall of the fifth sub-radiator 425.

[0263] In this embodiment, the antenna radiator 42 can also be retractable by other structures, not limited to the above. For example, each segment of the antenna radiator 42 can be plate-shaped or groove-shaped, and every two adjacent segments of the sub-radiators are slidably connected.

[0264] In the fourth embodiment, the antenna radiator 42 is electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module on the circuit board through the spring piece, so that it can receive and send Beidou short messages. Alternatively, the antenna radiator 42 can send and receive both Beidou signals and the first network signals in a multiplexing manner. "Multiplexing" includes but is not limited to time-division multiplexing of the antenna radiator 42 through software design and / or switching circuits, and sending and receiving Beidou signals and the first network signals at different times; or frequency-division multiplexing of the antenna radiator 42, and sending and receiving Beidou signals and the first network signals at the same time. Therefore, the wearable device 40 of the fourth embodiment can meet the user's communication needs in emergency scenarios, and can also meet the user's usage needs in daily scenarios.

[0265] Embodiment 4 Fig. 27 and Fig.28 Only one antenna radiator 42 is shown. It is understandable that the wearable device 40 may also have a larger number of such antenna radiators 42, for example, at least 2. When the wearable device 40 has multiple antenna radiators 42, each antenna radiator 42 may not need to be reused, or at least one of the antenna radiators 42 may be reused.

[0266] In the fourth embodiment, a retractable antenna radiator 42 is designed. When the antenna radiator 42 is extended, the effective length of the antenna radiator 42 increases, and the distance from the circuit board assembly, the display screen 43 and the user's arm increases, which is beneficial to enhancing the antenna performance of the antenna radiator 42.

[0267] In the fourth embodiment, schematically, the antenna radiator 42 mounted on the peripheral side of the housing 41 can also be used as a button of the wearable device 40. When the user presses and / or rotates the button (for example, when the antenna radiator 42 is in a folded state), a corresponding operation can be triggered, such as selection, confirmation, screen switching, etc. Of course, the design of the antenna radiator 42 having a button function is not necessary.

[0268] Embodiment 5

[0269] like Fig.29 and Fig.30As shown, the fifth embodiment provides a wearable device 50, which may be, for example, a smart watch. The wearable device 50 may include a housing 54, an ear axis 53, a strap 52, an ear axis 55, a strap 56, an antenna radiator 51, and an antenna radiator 57. The wearable device 50 may also include a circuit board 59, a shrapnel 58, a shrapnel 60, a processor, a Beidou communication module, other communication modules, a display screen, and the like.

[0270] Among them, the processor, Beidou communication module, and other communication modules are all arranged on the circuit board. Shrapnel 58 and shrapnel 60 are both installed on the circuit board 59, and the shrapnel 58 can be electrically connected to the first communication module on the circuit board 59, and the shrapnel 60 can be electrically connected to the satellite positioning unit and the short message unit in the Beidou communication module on the circuit board 59. The circuit board, shrapnel, processor, Beidou communication module, and other communication modules are all located in the installation space of the shell 54. The display screen can be installed on the shell 54. The shell 54, the electronic devices and structures installed in the installation space of the shell 54 or on the shell 54 can constitute the host of the wearable device 50.

[0271] In the fifth embodiment, the structure of the housing 54 is not specifically limited. Different from the above-mentioned housings, the housing 54 does not have a receiving cavity for mounting the antenna radiator, that is, the antenna radiator is not mounted in the receiving cavity.

[0272] The specific structure of the ear shaft 53 and the ear shaft 55 is not limited. The ear shaft 53 and the ear shaft 55 are respectively connected to the two sides of the shell 54. The ear shaft 53 can be assembled to the shell 54 (the ear shaft 53 can be fixedly connected or rotatably connected to the shell 54), or it can be connected to the shell 54 as a whole (the ear shaft 53 is fixedly connected to the shell 54). The ear shaft 53 is connected to the spring sheet 60, and the ear shaft 53 can be made of a conductive material, such as a metal material. The ear shaft 55 can be assembled to the shell 54 (the ear shaft 55 can be fixedly connected or rotatably connected to the shell 54), or it can be connected to the shell 54 as a whole (the ear shaft 55 is fixedly connected to the shell 54). The ear shaft 55 is connected to the spring sheet 58, and the ear shaft 55 can be made of a conductive material, such as a metal material. The ear shaft 53 and the ear shaft 55 are both used to achieve relative rotation between the wearer and the shell 54.

[0273] The strap 52 is connected to the housing 54 via the ear shaft 53 and can rotate relative to the housing 54. For example, when the ear shaft 53 is fixedly connected to the housing 54, the strap 52 can be rotationally connected to the ear shaft 53, for example, the end of the strap 52 can wrap around the ear shaft 53 and rotate around the ear shaft 53. Alternatively, when the ear shaft 53 is rotationally connected to the housing 54, the strap 52 can be fixedly connected to the ear shaft 53, and the strap 52 and the ear shaft 53 rotate relative to the housing 54 together.

[0274] The strap 56 is connected to the housing 54 via the ear shaft 55 and can rotate relative to the housing 54. For example, when the ear shaft 55 is fixedly connected to the housing 54, the strap 56 can be rotatably connected to the ear shaft 55, for example, the end of the strap 56 can wrap around the ear shaft 55 and rotate around the ear shaft 55. Alternatively, when the ear shaft 55 is rotatably connected to the housing 54, the strap 56 can be fixedly connected to the ear shaft 55, and the strap 56 and the ear shaft 55 rotate relative to the housing 54 together.

[0275] The strap 52 and the strap 56 can be made of soft insulating materials, such as nylon, braided fabric, etc. The strap 52 and the strap 56 located on both sides of the housing 54 can be wrapped around a human body part (such as a wrist) and form a detachable connection (such as a lock connection) to enable the wearable device 50 to be worn.

[0276] The antenna radiator 51 may be located inside the strap 52, and the antenna radiator 51 is wrapped by the material of the strap 52, that is, the antenna radiator 51 and the strap 52 may form a sandwich structure. The antenna radiator 51 may rotate along with the strap 52. One end of the antenna radiator 51 may be connected to the ear shaft 53, for example, this end of the antenna radiator 51 may be rotatably connected to the ear shaft 53. Schematically, this end of the antenna radiator 51 may approximately form a cylindrical structure, and the cylindrical structure may be rotatably sleeved on the ear shaft 53, so as to realize the rotatable connection between the antenna radiator 51 and the ear shaft 53.

[0277] The antenna radiator 57 may be located inside the strap 56, and the antenna radiator 57 is wrapped by the material of the strap 56, that is, the antenna radiator 57 and the strap 56 may form a sandwich structure. The antenna radiator 57 can rotate with the strap 56. One end of the antenna radiator 57 may be connected to the ear shaft 55, for example, this end of the antenna radiator 57 may be rotatably connected to the ear shaft 55. Schematically, this end of the antenna radiator 57 may approximately form a cylindrical structure, and the cylindrical structure may be rotatably sleeved on the ear shaft 55, so as to realize the rotatable connection between the antenna radiator 57 and the ear shaft 55.

[0278] Combination Fig.30 As shown, the antenna radiator 51 can be electrically connected to the Beidou communication module on the circuit board 59 through the ear axis 53 and the spring 60, thereby realizing the function of receiving and sending Beidou short messages. The antenna radiator 51 can also transmit and receive both Beidou signals and first network signals through time division multiplexing or frequency division multiplexing. The antenna radiator 57 can be electrically connected to the ground communication module on the circuit board 59 through the ear axis 55 and the spring 58, thereby realizing the function of transmitting and receiving the first network signal. The antenna radiator 57 can also transmit and receive both the first network signal and Beidou signals through time division multiplexing or frequency division multiplexing.

[0279] It is understandable that the above mention of using antenna radiator 51 as a Beidou antenna radiator and antenna radiator 57 as other antenna radiators is only an example and is not a limitation of the solution of Embodiment 5. For example, antenna radiator 51 can also be used as other antenna radiators and antenna radiator 57 can be used as a Beidou antenna radiator.

[0280] The wearable device 50 of the fifth embodiment can meet the communication needs of users in emergency scenarios and the usage needs of users in daily scenarios. In addition, by arranging the antenna radiator in the wearable device and electrically connecting the antenna radiator to the communication module through the ear axis and the spring, the internal space of the wearable device can be effectively used to arrange the antenna radiator, saving the internal space of the host of the wearable device 50. In addition, by arranging the antenna radiator in the wearable device, the antenna radiator is far away from the circuit board assembly of the wearable device 50, which can ensure the antenna performance of the antenna radiator.

[0281] The hardware structure of the wearable device of the embodiment of the present application is described in detail above. The following will describe the method for sending a Beidou short message applied to the wearable device.

[0282] Embodiment 6

[0283] Embodiment 6 provides a method for sending a Beidou short message, which is applicable to any of the above wearable devices. The sending method may include:

[0284] When the processor of the wearable device receives an input signal and / or determines that the current environment meets the trigger condition, it controls the Beidou communication module to send a Beidou short message through the antenna radiator.

[0285] The wearable device may be any one of the wearable devices 10 to 50, and the antenna radiator may be a dedicated Beidou antenna radiator in the wearable device, or an antenna radiator multiplexed as a Beidou antenna radiator and other antenna radiators. The processor controls the Beidou communication module to send Beidou short messages through the antenna radiator, that is, controls the short message unit in the Beidou communication module to send Beidou short messages through the antenna radiator.

[0286] The input signal may be a signal generated by the human-computer interaction module of the wearable device in response to a user operation, and the input signal is used to trigger the Beidou short message function. The human-computer interaction module includes but is not limited to a display screen 14 or a display screen 23, a button (installed on the housing 11 or the housing 21), a microphone, and the like. For example, the display screen 14 or the display screen 23 generates an input signal in response to a user's touch operation. Alternatively, the button receives a user's press and / or rotation operation, and the button circuit may generate an input signal. Alternatively, the microphone receives a voice input by the user and generates an input signal.

[0287] In the sixth embodiment, the processor of the wearable device can determine that the user wants to send a Beidou short message according to the user operation. Then, the processor controls the Beidou communication module to send the Beidou short message through the antenna radiator. This is a mechanism for the user to manually send a Beidou short message.

[0288] The current environment may include at least one of a working state of the wearable device, a current time, a natural environment parameter in which the wearable device is located, and a physical sign parameter of a user wearing the wearable device.

[0289] The working status of the wearable device may include the network environment, such as the signal strength of the cellular network, the signal strength of the Beidou satellite network, etc. The natural environment parameters may include the temperature, humidity, wind speed, height, depth, ultraviolet intensity, ambient light intensity, CO 2 Concentration, air pressure, location information of wearable devices, etc. The user's vital signs parameters may include blood pressure, blood flow rate, body temperature, heart rate, blood oxygen, electrocardiogram, heart and lung sounds, respiratory rate, skin water content, falls, tremors, etc.

[0290] Wearable devices can detect the current environment through corresponding modules. For example, the natural environment parameters of the wearable device can be detected through the natural environment monitoring module, such as detecting the current ambient light intensity through the ambient light sensor, detecting the south direction through the geomagnetic sensor, and detecting the current temperature through the temperature sensor. For example, the user's physical sign parameters can be detected through the physical sign detection module, such as detecting the user's movement posture through the gyroscope and acceleration sensor (to determine whether it falls or trembles), detecting the user's body temperature through the body temperature sensor, detecting the user's blood oxygen through the blood oxygen sensor, and measuring the user's heart rate through the PPG photoelectric sensor.

[0291] Trigger conditions refer to rules built into wearable devices that can be fixed or customized to trigger the Beidou short message function.

[0292] For example, if the current environment is a network environment, the trigger condition may include at least one of the following: the duration of time that the signal strength of the cellular network is less than the signal strength threshold exceeds the set duration, and the signal strength of the Beidou satellite network is less than the signal strength threshold. That is, if the signal strength of the wearable device in the cellular network is too weak, or even in a network environment without a cellular network for a certain period of time (such as 10 minutes), and / or the signal strength of the Beidou satellite network is too weak, the processor will control the Beidou communication module to send a Beidou short message through the antenna radiator.

[0293] For example, if the current environment is the current time, the trigger condition may include that the current time is a set time. That is, if the current time reaches the set time, the processor will control the Beidou communication module to send a Beidou short message through the antenna radiator.

[0294] For example, if the current environment is a natural environment parameter and / or a vital sign parameter, the trigger condition may include at least one of a deviation between the natural environment parameter and a set value exceeding a threshold value, and a deviation between the vital sign parameter and a set value exceeding a threshold value. That is, when a sudden change or abnormality occurs in the natural environment parameter and / or the vital sign parameter, the processor controls the Beidou communication module to send a Beidou short message through the antenna radiator.

[0295] When the above-mentioned natural environment parameters and physical sign parameters suddenly change or become abnormal, the processor can automatically collect and analyze the natural environment information and physical sign information, and give corresponding risk reduction measures and suggestions. For example, users can be advised to adjust their activity level, replenish oxygen / water / sugar, maintain body temperature, go to a safe place, etc. These measures and suggestions can be pre-built into the wearable device, or the wearable device can communicate with the rescue platform through the Beidou satellite and receive it from the rescue platform.

[0296] In Embodiment 6, the processor can determine whether the current environment meets the trigger condition. When it is confirmed that the current environment meets the trigger condition, the processor controls the Beidou communication module to send the Beidou short message through the antenna radiator. This is a mechanism for automatically sending Beidou short messages. Under the mechanism of automatically sending Beidou short messages, there may be a user confirmation step before sending the Beidou short message. After the user confirms, the Beidou short message is sent.

[0297] The two Beidou short message sending mechanisms in Example 6 are independent of each other and can be executed simultaneously or one by one.

[0298] The Beidou short message function not only has high requirements on the power supply, but also has a great impact on battery energy consumption and battery life. In view of this, the sixth embodiment can adopt the following flexible and intelligent short message function power saving solutions:

[0299] In the sixth embodiment, controlling the Beidou communication module to send the Beidou short message through the antenna radiator may include: controlling the Beidou communication module to send the Beidou short message through the antenna radiator according to a sending strategy.

[0300] In implementation mode one, the sending strategy may include: when the remaining number of Beidou short messages that can be sent is lower than a threshold, and / or the remaining power of the wearable device is lower than a threshold, selecting the Beidou short message with the highest priority in the Beidou short message list for sending; or, reorganizing and sending the Beidou short messages in the Beidou short message list, wherein the reorganization includes but is not limited to semantic extraction and concentration, word trimming, extracting multiple keywords into one Beidou short message, etc.; or, sending the Beidou short message selected by the user from the Beidou short message list.

[0301] The remaining number of Beidou short messages that can be sent can be determined by comprehensively considering the remaining power of the wearable device and the energy consumption of sending and receiving Beidou short messages. The remaining power and the remaining number of Beidou short messages that can be sent can be prompted on the user interaction interface. For reference, the user interaction interface is as follows: Fig.31 shown.

[0302] Indicatively, the list of Beidou short messages to be sent can be queried, and the Beidou short message with the highest priority can be automatically selected for sending. Alternatively, the user can be prompted to manually select a Beidou short message from the Beidou short message list, and the Beidou short message selected by the user can be sent. Alternatively, the Beidou short messages in the Beidou short message list can be automatically reorganized according to streamlining operations such as semantic saving, clipping, and packaging keywords, and the reorganized Beidou short message can be sent.

[0303] Before sending a Beidou short message, a prompt can be given on the user interaction interface to ask the user to select the sending method. Fig.32 shown.

[0304] In implementation mode 2 of embodiment 6, different from implementation mode 1 above, the sending strategy may include: when the state indicated by the vital sign information, natural environment information and / or power information is a safe state, the Beidou short message to be sent is first cached, and when it is detected that the user operates the wearable device, the cached Beidou short message is sent; when the state indicated by the vital sign information, natural environment information and / or power information is an unsafe state, the Beidou short message is sent directly.

[0305] In the second embodiment, the processor can integrate the information of the vital sign detection module, the natural environment monitoring module, and the power supply module to conduct a comprehensive assessment of the safety status of the wearable device or the user. The assessment results include a safe state and an unsafe state. In a safe state, the wearable device can operate normally, reliably, and sustainably, or the user can carry out activities normally. In an unsafe state, the wearable device cannot maintain normal, reliable, and sustainable operation, or the user cannot carry out activities normally.

[0306] In the second embodiment, when the evaluation result indicates that the state of the wearable device or the state of the user is a safe state, the processor can cache the Beidou short message to be sent to the storage module, and send the cached Beidou short message when it is detected that the user operates the wearable device. For example, when it is detected that the user raises his wrist, try to send the Beidou short message in the background. In this way, frequent satellite searches and Beidou short message sending behaviors due to random activities of users or unsatisfactory Beidou satellite signals can be avoided, thereby saving power.

[0307] In the second embodiment, when the evaluation result indicates that the state of the wearable device or the user is in an unsafe state, a Beidou short message can be directly sent so as to be able to communicate with the outside world in a timely manner. The content of the Beidou short message may include necessary information characterizing the unsafe state, such as key vital sign parameters such as heart rate, blood oxygen, body temperature, and key natural environment parameters such as temperature, location information, altitude, and air pressure.

[0308] The above implementation method of Example 6, by setting a built-in strategy and sending Beidou short messages according to the built-in strategy, can selectively send Beidou short messages according to user needs when the wearable device is low on power, so as to reasonably utilize the remaining power of the device, meet user needs, and enhance user experience.

[0309] In the sixth embodiment, illustratively, the content of the sent Beidou short message may include at least one of natural environment parameters, vital sign parameters, preset information, and user-defined information.

[0310] The preset information may be information pre-installed in the wearable device. In principle, the preset information may be an emergency description or a distress message, such as a sudden natural disaster, a life threat, a shortage of spare materials, helping other rescued objects to seek help, or performing special sports or activities (such as diving, sailing, sailing, mountaineering, rock climbing, off-roading, exploration, skiing, wing suit flying, aviation driving, parachuting, etc.).

[0311] Among them, user-defined information is information edited and input by the user. The user can edit the user-defined information on other external devices that are easy to input (such as mobile phones, tablet computers and other external devices with large input interfaces). The wearable device can receive the user-defined information from the external device through other communication modules, and send the received user-defined information in the form of Beidou short messages.

[0312] Fig.33 A flowchart showing the sending mechanisms of the several Beidou short messages mentioned above.

[0313] The solution of Example 6 enables the wearable device to send Beidou short messages, so that the wearable device can communicate with the outside world in an environment without a network, thereby meeting the communication needs of users in emergency scenarios.
