[0060] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0061] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0062] In related technologies, watches rely on high-frequency positioning, specifically using the L1 and L5 bands of GPS (Global Positioning System) to obtain current location, date, and time. The L1 band in GPS operates at 1575.42MHz, has weak signal strength, significant free-space attenuation, and a positioning accuracy of 5-10 meters, making it suitable for short-distance, low-precision scenarios. The L5 band operates at 1176.45MHz, with 6dB higher signal power than the L1 band, offering stronger anti-interference and anti-multipath capabilities, making it suitable for high-precision scenarios. While the L1 band has wide coverage, its accuracy is limited; the L5 band offers high accuracy and is suitable for complex environments. When used in conjunction with the L1 band for dual-frequency positioning, ionospheric delay errors can be eliminated, achieving sub-meter positioning accuracy and maximizing its advantages.

[0063] However, in actual testing of existing watches, especially sports watches (also known as running watches), the watch's trajectory deviates from its path in some complex scenarios, especially those with obstacles. The antenna efficiency is poor, especially the efficiency of the L5 band, making it difficult for the watch to achieve accurate positioning.

[0064] The watch provided in this application uses the casing to house an antenna, which is also connected to the motherboard. The watch lugs are also connected to the motherboard, thereby increasing the antenna's extension and improving its performance, which in turn improves the accuracy of the watch's positioning.

[0065] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0066] This application provides a watch, see embodiments thereof. Figures 1 to 7 The watch 10 is, for example, a smartwatch. The watch 10 includes a housing 20, a mainboard 50, and lugs 40. The housing 20 is the main structure of the watch 10, protecting its internal components and also forming an antenna. The housing 20 has a receiving cavity and a first through-hole 26. The receiving cavity can be cylindrical, elliptical, frustum-shaped, or drum-shaped. The receiving cavity houses the mainboard 50, which, for example, is fixedly mounted on the housing 20. The mainboard 50 includes printed circuit boards (PCBAs), flexible printed circuit boards (FPCs), etc. The receiving cavity may also accommodate other structures necessary to ensure the normal operation of the watch 10, such as a charging module and a battery.

[0067] The housing 20 has a first through hole 26 that penetrates the housing 20 and communicates with the receiving cavity. The first through hole 26 allows the grounding post 41 of the lug 40 to extend into and connect to the main board 50. The housing 20 is equipped with an antenna; exemplarily, a portion of the housing 20 forms the antenna, specifically an antenna radiator, meaning the housing 20 integrates antenna functionality to achieve signal transmission and reception. In this way, the antenna radiator is exposed, free from interference from other components, increasing the clear area of ​​the antenna radiator, increasing its radiation capability to generate different signal frequency bands, increasing bandwidth, and improving communication quality.

[0068] The antenna is also electrically connected to the motherboard 50. Specifically, the housing 20 is electrically connected to corresponding modules (such as RF units and ground wires) on the motherboard 50 to enable signal conduction of the antenna. The housing 20 may have a feed terminal and at least one ground terminal. The feed terminal connects to the RF unit on the motherboard 50, and each ground terminal connects to the ground wire on the motherboard 50. The portion of the housing 20 between the feed terminal and the ground terminal forms the antenna. When there are multiple ground terminals, the housing 20 can form antenna radiators of different lengths as needed, thus corresponding to different antenna types, such as GPS antennas, Bluetooth antennas, WIFI antennas, 4G antennas, 5G antennas, etc. The housing 20 can directly contact the corresponding modules on the motherboard 50 or be connected via connectors to achieve electrical conduction.

[0069] In some possible embodiments, the housing 20 includes a middle frame 21 and a bezel 22. The middle frame 21 has a first through hole 26 and is fixedly connected to the lug 40. The bezel 22 is disposed on the side of the middle frame 21 opposite to the lug 40 and is fixedly connected to the middle frame 21. The middle frame 21 and the bezel 22 are arranged along the thickness direction of the housing 20 and enclose a receiving cavity with openings at both ends. The middle frame 21 is fitted with the lug 40 and has the first through hole 26. The bezel 22 is connected to the end of the middle frame 21 opposite to the lug 40, specifically disposed at the top of the middle frame 21.

[0070] The bezel 22 is a metal bezel that forms an antenna, specifically an antenna radiator, ensuring clearance for the antenna radiator and improving antenna performance. The bezel 22 can be made of materials including, but not limited to, amorphous alloys, stainless steel, titanium alloys, and aluminum alloys. The middle frame 21 can be a plastic frame, specifically an insulating polymer material, to give it a certain degree of elasticity. The middle frame 21 can be made of materials including, but not limited to, polyamide (PA), PA glass fiber, and polybutylene terephthalate (PBT). The bezel 22 and middle frame 21 can also be made of other materials; this embodiment is not limited to these.

[0071] In some possible embodiments, the housing 20 further includes a front panel 23 and a back panel 24. The front panel 23 is disposed within the bezel 22 and fixedly connected to the bezel 22. The back panel 24 is disposed at the end of the middle frame 21 opposite to the bezel 22 and fixedly connected to the middle frame 21. The front panel 23 and the back panel 24 are respectively disposed at the top and bottom of the receiving cavity. The front panel 23 forms the front of the watch 10, and the back panel 24 forms the back of the watch 10. The side of the middle frame 21 facing the central axis of the housing 20 forms the inner side of the middle frame 21, and the side of the middle frame 21 opposite to the central axis of the housing 20 forms the outer side of the middle frame 21. The front panel 23 includes a display screen, such as a flexible display screen or a liquid crystal display screen, and may further include a touch screen. The back panel 24 may be made of the same material as the middle frame 21 or a different material; for example, the back panel 24 may be a plastic back panel or a metal back panel.

[0072] In the above embodiments, the panel 23, bezel 22, middle frame 21, and bottom shell 24 are all sealed together, which can improve the waterproof performance of the shell 20. The methods of fixing and sealing between the panel 23, bezel 22, middle frame 21, and bottom shell 24 are not limited. The panel 23 and bezel 22, the bezel 22 and middle frame 21, and the middle frame 21 and bottom shell 24 can be fixedly connected by fasteners, interference fits, snap-fits, etc.; the panel 23 and bezel 22, the bezel 22 and middle frame 21, and the middle frame 21 and bottom shell 24 can be sealed together by interference fits, sealing rings 90, sealant, etc. For example, an annular sealing ring 90 is provided between the bezel 22 and the middle frame 21, and sealant is provided between the bezel 22 and the panel 23.

[0073] At least one button 30 is also provided on the outer side of the housing 20 for adjusting the mode, calibrating the time, etc. of the watch 10. For example, the button 30 is located on the outer side of the middle frame 21, and at least a part of the structure of the button 30 can rotate or slide relative to the middle frame 21. The specific shape and structure of the button 30, the connection relationship between the button 30 and the middle frame 21, and the connection relationship between the button 30 and the mainboard 50 are not limited.

[0074] Continue reading Figures 1 to 7 The lugs 40 are disposed on the housing 20, specifically on the mid-frame 21, for example, on the outer side of the mid-frame 21 and extending to the inner side of the mid-frame 21. The lugs 40 connect to the watch strap, and there can be two symmetrically arranged lugs 40, each connecting to a different watch strap. In some possible examples, the lugs 40 are metal lugs to improve their texture and, by connecting to the main board 50, for example, to the ground wire of the main board 50, increase the extension of the antenna ground and improve antenna performance. The materials of the lugs 40 include, but are not limited to, amorphous alloys, stainless steel, titanium alloys, and aluminum alloys.

[0075] The lugs 40 are detachably connected to the frame 21, which enhances the overall quality of the watch 10 and allows for replacement to provide different color options. In some possible implementations, the lugs 40 can be fastened to the case 20 with fasteners to improve their mechanical and grounding stability. Of course, the lugs 40 can also be fixed to the case 20 in other ways, such as by snap-fit.

[0076] For example, such as Figure 2 and Figure 3 As shown, the housing 20 has a threaded hole, and the lugs 40 have corresponding mounting holes 45. The watch 10 also includes screws 80, the head of which abuts against the lugs 40, and the shank of which passes through the mounting hole 45 and connects to the threaded hole. Multiple threaded holes, mounting holes 45, and screws 80 can be provided as needed; for example, one lug 40 can be connected to the housing 20 by two screws 80. The threaded holes, mounting holes 45, and screws 80 are arranged in a one-to-one correspondence, meaning each threaded hole corresponds to one mounting hole 45 and is provided with one screw 80.

[0077] Among them, such as Figure 3 and Figure 4 As shown, one of the housing 20 and the lug 40 is provided with a positioning post 25, and the other is provided with a corresponding positioning hole 44, with the positioning post 25 located within the positioning hole 44. The positioning fit between the positioning hole 44 and the positioning post 25 achieves positioning and tensile strength, ensuring the assembly of the lug 40 and the housing 20 and preventing the lug 40 from detaching from the housing 20. After the housing 20 and the lug 40 are positioned and fitted, the mounting hole 45 and the threaded hole are aligned, facilitating the tightening of the screw 80 to connect the housing 20 and the lug 40.

[0078] For example, the lug 40 is provided with a positioning hole 44, which may be a through hole or a countersunk hole. The housing 20 is provided with a positioning post 25, which is specifically located on the middle frame 21 and can form an integral structure with the middle frame 21. The positioning hole 44 and the positioning post 25 can be interference-fitted or clearance-fitted. The specific shape of the positioning post 25 is not limited, but the shape of the positioning hole 44 is adapted to the shape of the positioning post 25.

[0079] The lug 40 includes two lugs positioned opposite each other and a connecting part connecting the two lugs. The lugs and the connecting part can be an integral structure. Connecting holes 46 are provided on the opposing surfaces of the two lugs to mate with connecting rods on the watch strap. The connecting part is provided with mounting holes 45 and positioning holes 44 to ensure the strength of the lug 40.

[0080] like Figure 5 and Figure 7As shown, the lug 40 includes a grounding post 41, which passes through the first through-hole 26 and is located within the receiving cavity for electrical connection to the main board 50, for example, to the ground wire of the main board 50. Thus, by utilizing the grounding post 41 and the lug 40, the antenna's extended ground (also called a floor or reflector) can be increased, thereby enhancing the antenna's directivity and gain, reducing interference signals, improving impedance matching, stabilizing the radiation mode, and ultimately improving the antenna's performance, especially in the L5 band.

[0081] The grounding post 41 is disposed on the surface of the connecting part facing the middle frame 21, and the grounding post 41 is, for example, an integral structure with the connecting part. In the example where there are two lugs 40, the grounding post 41 can be disposed on only one of the lugs 40.

[0082] In some possible embodiments, the grounding post 41 includes a post 42 and a protrusion 43. The post 42 is located within the first through hole 26; the protrusion 43 is disposed at one end of the post 42 and located within the receiving cavity, with its outer peripheral surface protruding beyond the inner peripheral surface of the post 42. The post 42 and the protrusion 43 can be an integral structure. The post 42 can be, for example, a cylindrical post 42, an elliptical post 42, a rectangular post, etc., and the shape of the protrusion 43 can be the same as or different from the shape of the post 42.

[0083] The column 42 is disposed on the connecting portion, which has a corresponding groove. The column 42 is disposed within the groove and is also located within the first through hole 26. A protrusion 43 is disposed at the end of the column 42 away from the connecting portion. The axes of the protrusion 43 and the column 42 can be parallel, for example, coincident. The protrusion 43 is also located within a receiving cavity to connect to the main board 50. The surface of the protrusion 43 facing away from the main body can be a flat surface or a concave arc surface. The outer peripheral surface of the protrusion 43 protrudes beyond the outer peripheral surface of the column 42, thus increasing the cross-sectional size of the protrusion 43 and improving the contact area.

[0084] In some possible implementations, the middle frame 21 is elastic, and the first through hole 26 includes at least two hole segments connected in sequence. The first through hole 26 includes at least two hole segments with different diameters, and adjacent hole segments form stepped surfaces facing towards or away from the receiving cavity. Along the direction close to the bezel 22, the diameters of the at least two hole segments decrease sequentially; the outer peripheral surface of the protrusion 43 protrudes from the inner peripheral surface of the hole segment closest to the bezel 22.

[0085] Here, the aperture refers to the diameter or equivalent diameter of the corresponding aperture segment. Among these aperture segments, the aperture segment closest to the bezel 22 has the smallest aperture, and the aperture segment furthest from the bezel 22 has the largest aperture. Thus, the first through hole 26 forms a stepped hole, and the size of the first through hole 26 decreases along the direction closer to the bezel 22. The outer peripheral surface of the protrusion 43 protrudes from the inner peripheral surface of the aperture segment closest to the bezel 22, and the middle frame 21 is elastic. In this way, the protrusion 43 deforms by compressing the inner wall of the corresponding aperture segment to enter the receiving cavity through the first through hole 26, and can prevent it from falling out of the first through hole 26, thus limiting the protrusion 43 and facilitating its confinement within the receiving cavity.

[0086] The column 42 is spaced apart from each hole segment, meaning there is a gap between the column 42 and the inner wall of the first through hole 26, facilitating the entry of the column 42 into the first through hole 26. For example, the cross-sectional dimension of the column 42 is smaller than the cross-sectional dimension of the first hole segment and smaller than the cross-sectional dimension of the second hole segment, and the column 42 is spaced apart from both the first and second hole segments.

[0087] For example, at least two hole segments include a first hole segment and a second hole segment. One end of the first hole segment is located on the outer surface of the middle frame 21, and the other end of the first hole segment is connected to one end of the second hole segment. The other end of the second hole segment is located on the inner surface of the middle frame 21. The diameter of the first hole segment is larger than the diameter of the second hole segment, and a stepped surface facing outward of the receiving cavity is formed between the first hole segment and the second hole segment.

[0088] The outer peripheral surface of the protrusion 43 protrudes from the inner peripheral surface of the second hole section and is recessed into the inner peripheral surface of the first hole section. That is, the cross-sectional dimension of the protrusion 43 is larger than the cross-sectional dimension of the second hole section and smaller than the cross-sectional dimension of the first hole section, which facilitates the protrusion 43 to pass through the first hole section and be squeezed into the receiving cavity by the second hole section, and makes it difficult for it to retreat into the second hole section.

[0089] To ensure the sealing performance of the watch 10's internal components, such as... Figures 5 to 7 As shown, the watch 10 also includes a sealing ring 90, which is sleeved on the grounding post 41 and located inside the first through hole 26. The sealing ring 90 abuts against both the grounding post 41 and the housing 20. The sealing ring 90 achieves a circumferential seal between the grounding post 41 and the first through hole 26, preventing moisture and other substances from entering through the gap between the grounding post 41 and the first through hole 26, thus achieving water resistance for the watch 10.

[0090] The sealing ring 90 is fitted onto the column 42, abutting against the outer circumferential surface of the column 42 and also against the inner circumferential surface of the first through hole 26. In an example where the first through hole 26 includes at least two segments, the sealing ring 90 can be disposed in the segment furthest from the receiving cavity, facilitating installation of the sealing ring 90 from the outside of the housing 20. More specifically, the sealing ring 90 is disposed in the first segment, so that the stepped surface formed by the first and second segments can also limit the sealing ring 90, preventing it from moving into the receiving cavity and ensuring a sealing effect.

[0091] In some possible examples, the watch 10 also includes a shielding cover 60 and a flexible connecting piece 70. The shielding cover 60 is disposed on the mainboard 50 and covers at least a portion of the mainboard 50. The flexible connecting piece 70 is disposed within a receiving cavity, with one end of the flexible connecting piece 70 fixedly connected to one of the shielding cover 60 and the grounding post 41, and the other end of the flexible connecting piece 70 abutting against the other of the shielding cover 60 and the grounding post 41. By using the flexible connecting piece 70 and the shielding cover 60 covering the mainboard 50 to connect the mainboard 50 and the lugs 40, no additional connection area needs to be reserved on the mainboard 50, thus saving space on the mainboard 50.

[0092] like Figure 6 and Figure 7 As shown, the shielding cover 60 is disposed on the motherboard 50 and covers corresponding structures or devices on the motherboard 50, such as radio frequency units of different antenna types, to provide electromagnetic shielding for the covered structures or devices and reduce electromagnetic interference. The shielding cover 60 may cover all or part of the corresponding structures or devices and is spaced apart from the covered structures or devices to avoid connection.

[0093] The shielding cover 60 is conductive, for example, the material of the shielding cover 60 is conductive ceramic or metal. For example, the shielding cover 60 is made of metal. The shielding cover 60 and the motherboard 50 can be soldered or bonded with conductive adhesive. Soldering the shielding cover 60 and the motherboard 50 can improve the stability of the connection between the two and improve the electromagnetic shielding capability, preventing electromagnetic waves from interfering with the structure or devices inside the shielding cover 60 through the connection between the shielding cover 60 and the motherboard 50.

[0094] One end of the flexible connecting piece 70 is connected to the shield 60, and the other end is connected to the grounding post 41. For example, one end of the flexible connecting piece 70 is fixedly connected to the shield 60 (e.g., welded), and the other end abuts against the grounding post 41; or, for another example, one end of the flexible connecting piece 70 is fixedly connected to the grounding post 41 (e.g., welded), and the other end abuts against the shield 60. The flexible connecting piece 70 is elastic so that, after connection, its own elasticity can maintain reliable contact with the shield 60 / grounding post 41.

[0095] In some possible implementations, one end of the elastic connecting piece 70 is welded to the surface of the shield 60 facing away from the motherboard 50 to facilitate connection and increase the connection area, ensuring connection reliability. In other implementations, one end of the elastic connecting piece 70 may also be welded to the side of the shield 60 or bonded with conductive adhesive. The other end of the elastic connecting piece 70 abuts against the top surface of the grounding post 41, specifically against the surface of the protrusion 43 facing away from the post 42.

[0096] The end of the elastic connecting piece 70 adjacent to the grounding post 41 can be bent to form a protrusion, or wound into a cylindrical structure and pressed against the grounding post 41. The elasticity of the connecting piece 70 allows it to reliably press against the grounding post 41, ensuring a reliable connection. The elastic connecting piece 70 can be, for example, a metal elastic connecting piece, and its material includes, but is not limited to, amorphous alloys, stainless steel, titanium alloys, and aluminum alloys.

[0097] During the assembly of the watch 10, the sealing ring 90 is passed through the protrusion 43 and fitted onto the post 42, thus installing the sealing ring 90 onto the lug 40. The shield 60 is then welded to the main board 50, and the elastic connecting piece 70 is welded to the shield 60. When installing the lug 40 and the middle frame 21, the elastic deformation of the middle frame 21 allows the protrusion 43 to pass through the first through hole 26, press against the middle frame 21, and abut against the elastic connecting piece 70. After assembly, the lug 40 is connected to the shield 60 via the elastic connecting piece 70, achieving grounding, and the sealing ring 90 provides waterproofing for the lug 40.

[0098] The watch 10 provided in this embodiment includes a housing 20, a main board 50, and lugs 40. The housing 20 has a receiving cavity and a first through hole 26 communicating with the receiving cavity. An antenna is provided in the housing 20. The main board 50 is disposed in the receiving cavity and electrically connected to the antenna. The lugs 40 are disposed on the housing 20 and include a grounding post 41. The grounding post 41 passes through the first through hole 26 and extends into the receiving cavity. The grounding post 41 is electrically connected to the main board 50. By connecting the grounding post 41 of the lugs 40 to the main board 50, and by connecting the main board 50 to the antenna, the extension ground of the antenna can be increased, thereby enhancing the directivity and gain of the antenna, reducing interference signals, improving impedance matching, stabilizing the radiation mode, and thus improving the performance of the antenna and ensuring the positioning accuracy of the watch 10.
