Therefore, they cannot be understood as limitations on this application.

[0018] See also Figure 1 , Figure 1 This is a structural block diagram of a wrist-worn device provided in some embodiments of the present application.

[0019] like Figure 1 As shown, in some embodiments, the wrist-worn device 100 includes a first antenna radiator 10, a second antenna radiator 11 and a third antenna radiator 12; the first antenna radiator 10 supports communication in the Sub 1G frequency band, and the frequency range of Sub1G is 100MHz~1GHz; the second antenna radiator 11 supports the Beidou satellite communication frequency band; the third antenna radiator 12 supports the Beidou satellite positioning frequency band.

[0020] In the present application, by setting the first antenna radiator 10, the second antenna radiator 11 and the third antenna radiator 12, Sub 1G frequency band communication, Beidou satellite communication and Beidou satellite positioning can be realized. Since Beidou satellite communication can be realized, it can better meet the needs of users to communicate in some areas without base station coverage. Since Beidou satellite positioning can be realized, it is more conducive to users to record tracks, view maps, etc. Since Sub1G frequency band communication can be realized, compared with 2.4GHz communication, small-scale communication can be achieved while the transmission distance is longer, the power consumption is lower, and the anti-interference is stronger, thereby simultaneously meeting the user's needs for Beidou satellite communication, Beidou satellite positioning and small-scale low-power communication through the wrist-worn device 100.

[0021] The wrist-worn device 100 may be, but is not limited to, an electronic device such as a watch or a bracelet.

[0022] The first antenna radiator 10 being used to support communications in the Sub 1G frequency band may refer to, but is not limited to, that the electrical length of the first antenna radiator 10 supports communications in the Sub 1G frequency band.

[0023] The Beidou satellite communication frequency band includes the L band and the S band, the L band is 1616.0 MHz~1626.5 MHz, and the S band is 2483.5 MHz~2495.0 MHz.

[0024] Among them, the Beidou satellite positioning frequency bands include B1 band, B2 band and B3 band, the B1 band is 1561.098 MHz~1591.789 MHz, the B2 band is 1207.140 MHz~1242.390 MHz, and the B3 band is 1268.520 MHz~1298.170 MHz.

[0025] Please refer to Figure 2 and Figure 3, Figure 2 A schematic diagram of the structure of a wrist-worn device from a frontal perspective provided in some embodiments of the present application; Figure 3 This is a schematic structural diagram of a wrist-worn device from a rear perspective provided in some embodiments of the present application.

[0026] In some embodiments, such as Figure 2 and Figure 3 As shown, the wrist-worn device 100 includes a shell 20, a first pair of ear bodies 30 and a first connecting portion 40; the first pair of ear bodies 30 are arranged on the outer periphery of the shell 20, for cooperating with the wristband 50, and the first pair of ear bodies 30 include a first ear body portion 31 and a second ear body portion 32 spaced apart from each other; the first connecting portion 40 is connected between the first ear body portion 31 and the second ear body portion 32; at least one of the first antenna radiator 10, the second antenna radiator 11 and the third antenna radiator 12 is at least partially arranged in the first connecting portion 40.

[0027] Since the wrist-worn device 100 includes the first connecting portion 40 connected between the first ear portion 31 and the second ear portion 32, and the first pair of ear portions 30 are arranged on the outer periphery of the shell 20, that is, the first connecting portion 40 is also located on the outside of the shell 20, therefore, at least one of the first antenna radiator 10, the second antenna radiator 11 and the third antenna radiator 12 is at least partially arranged in the first connecting portion 40, which can reduce the influence of electronic components such as the motherboard in the wrist-worn device 100 on the radiation efficiency of the antenna radiator arranged in the first connecting portion 40.

[0028] In some embodiments, the first connecting portion 40 may be made of an insulating material / non-conductive material, for example, an insulating material such as plastic, glass, or ceramic.

[0029] Among them, the first ear body part 31 and the second ear body part 32 can be made of metal or non-metallic insulating material. When the first ear body part 31, the second ear body part 32 and the first connecting part 40 are made of the same material, the first ear body part 31, the second ear body part 32 and the first connecting part 40 can be an integrally molded structure. When the first ear body part 31, the second ear body part 32 and the first connecting part 40 are made of different materials, the first ear body part 31, the second ear body part 32 and the first connecting part 40 can be connected by welding, hot pressing, clamping, etc.

[0030] In some embodiments, such as Figure 1 and Figure 2As shown, the wrist-worn device 100 includes a second pair of ear bodies 60, and the second pair of ear bodies 60 includes a third ear body portion 61 and a fourth ear body portion 62, wherein the second pair of ear bodies 60 and the first pair of ear bodies 30 can be relatively arranged on both sides of the shell 20, that is, the second pair of ear bodies 60 and the first pair of ear bodies 30 are axially symmetrically arranged. For example, when the wrist-worn device 100 is worn on the user's arm, the first pair of ear bodies 30 and the second pair of ear bodies 60 are symmetrical about the axis of the length direction of the arm.

[0031] In some embodiments, such as Figure 1 and Figure 2 As shown, the wrist-worn device 100 further includes a second connecting portion 90 , which is connected to the third ear portion 61 and the fourth ear portion 62 .

[0032] In some embodiments, the assembly of the first ear body portion 31 , the second ear body portion 32 and the first connecting portion 40 and the assembly of the third ear body portion 61 , the fourth ear body portion 62 and the second connecting portion 90 are axisymmetric structures.

[0033] In some embodiments, as Figure 3 As shown, the second connecting portion 90, the third ear portion 61, and the fourth ear portion 62 are located on the top side A of the wrist-worn device 100, and the first ear portion 31, the second ear portion 32, and the first connecting portion 40 are located on the bottom side B of the wrist-worn device 100. The top side A is the side of the wrist-worn device 100 that is away from the user when the user wears the wrist-worn device 100 correctly and the arm is kept horizontal, and the bottom side B is the side of the wrist-worn device 100 that is closer to the user when the user wears the wrist-worn device 100 correctly and the arm is kept horizontal.

[0034] like Figure 2 and Figure 3 As shown, in some embodiments, the first antenna radiator 10 is disposed on the bottom side B, and the second antenna radiator 11 and the third antenna radiator 12 are disposed on the top side A.

[0035] In some embodiments, the Sub 1G frequency band may be a 400 MHz frequency band, and the first antenna radiator 10 is used to support short-range communication in the 400 MHz frequency band, where the short-range communication is communication with a communication distance of less than or equal to 5 kilometers.

[0036] Thus, the wrist-worn device 100 can realize wireless communication with other electronic devices within a range of less than or equal to 5 kilometers without the need for cellular communication, which facilitates application in some scenarios. For example, in remote areas where the cellular communication signal is poor, wireless communication can be carried out with other electronic devices through the small-range communication in the 400MHz frequency band supported by the first antenna radiator 10 in this application, thereby ensuring the reliability of the communication connection.

[0037] In some embodiments, the 400 MHz frequency band may be a frequency band corresponding to a certain frequency range with a resonant frequency of 400 MHz, for example, a frequency band corresponding to a frequency range of 300-500 MHz with a resonant frequency of 400 MHz.

[0038] In other embodiments, the first antenna radiator 10 may further support other frequency bands in the Sub 1G frequency band, or may support communications in other frequency bands outside the Sub 1G frequency band, and is not limited to the examples in the embodiments of this document.

[0039] In some embodiments, the first ear body portion 31 and / or the second ear body portion 32 are also made of insulating materials, such as plastic, glass, or ceramic. Figure 1 and Figure 2 As shown, at least a portion of the first antenna radiator 10 is disposed in the first connecting portion 40 .

[0040] In some embodiments, such as Figure 1 and Figure 2 As shown, the first antenna radiator 10 includes at least a first radiating section 101 and a second radiating section 102 connected to the first radiating section 101, the first radiating section 101 is arranged in the first connecting part 40, and the second radiating section 102 is arranged in the first ear body part 31 and / or the second ear body part 32.

[0041] Because the first connecting portion 40, the first ear portion 31, and the second ear portion 32 are all disposed outside the housing 20, the first radiating section 101 of the first antenna radiator 10 is disposed in the first connecting portion 40, and the second radiating section 102 is disposed in the first ear portion 31 or the second ear portion 32. This can further reduce the impact of electronic components such as the motherboard within the wrist-worn device 100 on the radiation efficiency of the first antenna radiator 10. Furthermore, by disposing a portion of the first antenna radiator 10 in the first connecting portion 40 and another portion in the first ear portion 31 and / or the second ear portion 32, the required installation space for the first antenna radiator 10 can be better met.

[0042] In other embodiments, the first antenna radiator 10 may also be entirely disposed in the first connecting portion 40 .

[0043] Among them, there is an angle between the first radiating section 101 and the second radiating section 102. The first radiating section 101 can be a strip, and in the first connecting portion 40 it can be but not limited to a straight line, a broken line or a curved line, etc., or the first radiating section 101 can also be a square, similar to a patch antenna, which is not limited here.

[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, at least a portion of at least one of the second antenna radiator 11 and the third antenna radiator 12 is disposed in the second connecting portion 90. In some embodiments, a portion of the second antenna radiator 11 is disposed in the second connecting portion 90, and another portion is disposed in the third ear portion 61. In some embodiments, a portion of the third antenna radiator 12 is disposed in the second connecting portion 90, and another portion is disposed in the fourth ear portion 62. In other embodiments, the second antenna radiator 11 and the third antenna radiator 12 may also be disposed in other locations in the wrist-worn device 100, which is not limited here.

[0045] Please refer to Figure 2-Figure 4 , Figure 4 This is a structural block diagram of a wrist-worn device provided in some embodiments of the present application.

[0046] In some embodiments, such as Figure 4 As shown, the wrist-worn device 100 further includes a first feed source 70, which is disposed in the shell 20, and the first feed source 70 is connected to the first radiation segment 101 or the second radiation segment 102, wherein the first feed source 70 is used to provide a feed signal.

[0047] Since the first radiating section 101 is connected to the second radiating section 102 , the first antenna radiator 10 can be excited by the feeding signal whether the first feed source 70 is connected to the first radiating section 101 or to the second radiating section 102 .

[0048] The first feed source 70 may also be connected to the first radiation section 101 or the second radiation section 102 via a connecting piece such as a spring.

[0049] In some embodiments, the entire first antenna radiator 10 may be suspended, that is, not grounded, forming a monopole antenna. In some embodiments, one end of the first antenna radiator 10 is grounded, and a portion near the other end is connected to the first feed 70, thereby forming an inverted-F antenna. For example, the end of the first radiating segment 101 not connected to the second radiating segment 102 is grounded, while the first feed 70 is connected to a location on the second radiating segment 102.

[0050] Among them, such as Figure 4 As shown, the wrist-worn device 100 may further include a circuit board 71, a radio frequency front-end module (RFFEM) 72, a radio frequency integrated circuit (RFIC) 73, and a baseband processor 74. The circuit board 71, the RF front-end module 72, the RF integrated circuit 73, and the baseband processor 74 may all be disposed in the housing 20, and the RF front-end module 72, the RF integrated circuit 73, and the baseband processor 74 may all be disposed on the circuit board 71. The first feed source 70 is also connected to the RF front-end module 72.

[0051] Exemplarily, in a transmission scenario, the baseband processor 74 synthesizes the data to be transmitted (digital signal) into a baseband signal, and modulates the baseband signal into a baseband modulated signal and sends it to the RF integrated circuit 73. The RF integrated circuit 73 converts the baseband modulated signal into an RF transmission signal. The RF transmission signal is mixed, amplified, filtered, and processed by the RF front-end module 72 and then transmitted to the first feed source 70. The first antenna radiator 10 can convert the feed signal from the first feed source 70 into an electromagnetic wave for radiation.

[0052] Exemplarily, in a receiving scenario, the first antenna radiator 10 can receive electromagnetic waves, convert the electromagnetic waves into electrical signals and transmit them to the first feed source 70, and through the RF front-end module 72 connected to the first feed source 70, switch to the corresponding receiving link through a device with a switching function in the RF front-end module 72, amplify, filter, mix and other processes the RF signal through the receiving link, and then send the RF signal to the RF integrated circuit 73, the RF integrated circuit 73 processes the RF signal into a baseband modulated signal, and transmits the baseband modulated signal to the baseband processor 74, the baseband processor 74 converts the baseband modulated signal into a baseband signal, and determines the information carried in the electromagnetic wave after converting the baseband signal into data.

[0053] In some embodiments, the first radiation section 101 is arranged inside the first connecting part 40 and is sealed and wrapped by the first connecting part 40, and the second radiation section 102 is arranged inside the first ear body part 31 and / or the second ear body part 32 and is sealed and wrapped by the first ear body part 31 and / or the second ear body part 32.

[0054] Thus, the first radiation section 101 and the second radiation section 102 can be prevented from being exposed, thereby preventing the first radiation section 101 and the second radiation section 102 from coming into contact with liquids, etc., and at the same time, it is beneficial for the appearance of the first connecting part 40, the first ear body part 31 and the second ear body part 32 of the wrist-worn device 100 to have a larger design space.

[0055] The first antenna radiator 10 may be an LDS (Laser Direct Structuring) antenna. The first radiating section 101 may be molded within the first connecting portion 40 through secondary injection molding, thereby being hermetically encapsulated by the first connecting portion 40. The second radiating section 102 may be molded within the first ear portion 31 and / or the second ear portion 32 through secondary injection molding, thereby hermetically encapsulating the first ear portion 31 and / or the second ear portion 32.

[0056] In some embodiments, such as Figure 2 and Figure 3 As shown, the first connecting portion 40 is plate-shaped, the housing 20 includes a bottom shell 21 and a side frame 22, the bottom shell 21 is connected to the side frame 22, the first pair of ear bodies 30 are arranged on the outer periphery of the side frame 22, and the first connecting portion 40 is inclined relative to the bottom shell 21.

[0057] Due to the characteristics of electromagnetic waves, horizontally polarized signals will generate polarization currents on the earth's surface when they are close to the ground. The polarization current generates heat energy due to the influence of the earth's impedance, causing the electric field signal to decay rapidly. Vertical polarization is not easy to generate polarization currents. Therefore, when the wrist-worn device 100 is worn on the arm and the arm is placed horizontally relative to the ground, the bottom shell 21 is horizontal relative to the ground, the first connecting portion 40 is tilted relative to the bottom shell 21, and the first antenna radiator 10 is at least partially arranged on the first connecting portion 40. This can make the electromagnetic waves emitted by at least part of the first antenna radiator 10 have a component in the vertical direction, thereby reducing the polarization current, avoiding significant energy attenuation, and ensuring effective signal propagation.

[0058] The side frame 22 is in a ring shape, specifically, but not limited to, a circular ring shape or a rectangular ring shape.

[0059] In some embodiments, such as Figure 2 As shown, the shell 20 also includes an upper cover 23, and the upper cover 23 includes a display screen. The display screen can be but is not limited to an organic light emitting diode (OLED) display screen, a liquid crystal display (LCD) screen, an LED display screen (for example, including a Micro-LED display screen, a Mini-LED display screen), etc. The upper cover 23 is connected to the side of the side frame 22 away from the bottom shell 21.

[0060] The bottom shell 21, the side frame 22 and the top cover 23 are arranged to form a cavity (not shown). When worn correctly, the bottom shell 21 is closer to the arm than the top cover 23.

[0061] Among them, the upper cover 23 can be but not limited to circular, elliptical, rectangular or irregular shapes, the side frame 22 can be but not limited to circular ring, rectangular ring, etc., and the bottom shell 21 can also be but not limited to circular, elliptical, rectangular or irregular shapes, etc.

[0062] In some embodiments, the first connecting portion 40 is connected between the first ear body portion 31 and the second ear body portion 32 , and is connected to the outer periphery of the side frame 22 .

[0063] Compared with the gap between the first connecting part 40 and the outer periphery of the side frame 22, since the first connecting part 40 is connected to the outer periphery of the side frame 22, the first radiation section 101 is arranged inside the first connecting part 40. Therefore, the first feed source 70 is connected to the first radiation section 101 without passing through the first ear body part 31 or the second ear body part 32 through a feeder to connect to the first radiation section 101, thereby simplifying the connection path between the first feed source 70 and the first radiation section 101.

[0064] In other embodiments, the first connecting portion 40 may also be spaced apart from the side frame 22 .

[0065] In some embodiments, the first connecting portion 40 is connected to the outer periphery of the first end of the side frame 22 away from the bottom shell 21, and the first connecting portion 40 extends from the first end of the side frame 22 in a direction away from the side frame 22 and close to the plane where the bottom shell 21 is located.

[0066] Since the bottom shell 21 is closer to the arm than the upper cover 23 in the correct wearing method, the first connecting portion 40 is connected to the outer periphery of the first end of the side frame 22 away from the bottom shell 21, and the first connecting portion 40 extends from the first end of the side frame 22 in a direction away from the side frame 22 and close to the plane of the bottom shell 21, which is convenient for wearing and can ensure that the first connecting portion 40 is tilted relative to the bottom shell 21, so that at least part of the electromagnetic waves emitted by the first antenna radiator 10 have a component in the vertical direction, thereby reducing the polarization current, avoiding significant energy attenuation, and ensuring effective signal propagation.

[0067] In some embodiments, such as Figure 2 and Figure 3 As shown, the first connecting portion 40 includes a first surface 401 and a second surface 402 relative to each other. The first surface 401 is farther away from the bottom shell 21 than the second surface 402. A side edge of the first surface 401 close to the side frame 22 is connected to a side of the side frame 22 away from the bottom shell 21.

[0068] The first surface 401 and the second surface 402 may be curved surfaces. In other embodiments, at least one of the first surface 401 and the second surface 402 may be a flat surface.

[0069] In some embodiments, a side edge of the second surface 402 away from the side frame 22 and a bottom surface of the bottom shell 21 away from the side frame 22 are located in the same plane.

[0070] Therefore, the first connecting portion 40 can have a larger area while being comfortable to wear, so as to facilitate the arrangement of at least a portion of the first antenna radiator 10 .

[0071] In some embodiments, such as Figure 2 and Figure 3 As shown, the wrist-worn device 100 further includes a spring ear 80 and a wristband 50. The two ends of the spring ear 80 are respectively connected to the first ear body 31 and the second ear body 32. The spring ear 80 is connected to the wristband 50. The first connecting portion 40 includes a first plate 41. The first plate 41 includes a first surface 401 and a second surface 402 opposite to each other. The first surface 401 is farther away from the bottom case 21 than the second surface 402, and the first surface 401 is farther away from the spring ear 80 than the second surface 402.

[0072] in, Figure 3The structure between the first ear body portion 31 and the second ear body portion 32 is the same as the structure between the third ear body portion 61 and the fourth ear body portion 62, and can be understood in this manner. However, it should be understood that in other embodiments, the structure between the first ear body portion 31 and the second ear body portion 32 may be different from the structure between the third ear body portion 61 and the fourth ear body portion 62.

[0073] Since the bottom shell 21 is closer to the arm than the upper cover 23 in the correct wearing method, the ear 80 and part of the wristband 50 are located between the first plate 41 and the arm in the correct wearing method. Therefore, the ear 80 cannot be seen after the wrist-worn device 100 is worn, making the appearance of the wrist-worn device 100 more concise after being worn.

[0074] In other embodiments, the ear 80 may be exposed after wearing, that is, the first plate 41 and the ear 80 are arranged side by side between the first ear portion 31 and the second ear portion 32 along the extending direction of the wristband 50 .

[0075] Please refer to Figure 3 and Figure 5 , Figure 5 Schematic diagram of the structure of a wrist-worn device from a rear perspective provided in some other embodiments of the present application.

[0076] Similar to the above embodiments, but different in that, in some embodiments, such as Figure 5 As shown, the first connecting portion 40 further includes a second plate 42 , the spring ear 80 is located between the first plate 41 and the second plate 42 , and at least a portion of the first antenna radiator 10 is disposed in the first plate 41 and / or in the second plate 42 .

[0077] Therefore, at least a portion of the first antenna radiator 10 can be disposed on the first board 41 and / or the second board 42 , and the first connecting portion 40 has a larger area for disposing the first antenna radiator 10 .

[0078] The first plate 41 and the second plate 42 may be spaced apart.

[0079] In other embodiments, when the first connecting portion 40 only includes the first plate 41 , that is, does not include the second plate 42 , it is beneficial to reduce the weight of the wrist-worn device 100 .

[0080] See also Figure 6 , Figure 6 This is a structural block diagram of a second antenna radiator provided in some embodiments of the present application.

[0081] In some embodiments, such as Figure 6 As shown, the second antenna radiator 11 includes a receiving radiator 111 and a transmitting radiator 112 .

[0082] Thus, the user can send information to Beidou satellites through the wrist-worn device 100, and can also receive information sent by Beidou satellites.

[0083] See also Figure 7 , Figure 7 A schematic diagram of a structure in which a receiving radiator is shared in some embodiments of the present application.

[0084] In some embodiments, such as Figure 7 As shown, the third antenna radiator 12 includes a grounding point G1, a feeding point S1 and a connection point M1, the grounding point G1 is used for grounding, and the feeding point S1 is used to access the feeding signal; the receiving radiator 111 includes a third radiator segment 111a and a fourth radiator segment 111b, the third radiator segment 111a is connected to the connection point M1 of the third antenna radiator 12, and the fourth radiator segment 111b is the radiator segment between the grounding point G1 and the connection point M1 in the third antenna radiator 12.
