Description

Technical Field

[0001] This utility model relates to the technical field of smartwatches, specifically a smartwatch with a metal casing serving as a GPS antenna. Background Technology

[0002] Smartwatches offer advantages such as convenience, intelligent data collection, and motion-sensing interaction. Beyond being mere accessories, smartwatches play a vital role in people's exercise, sleep, calls, and entertainment. Technological advancements and functional improvements will continue to transform people's lives. In addition to telling time, smartwatches offer various functions including reminders, navigation, calibration, monitoring, and interaction. Display methods include analog, numerical, and graphical representations. However, most current smartwatches use built-in antennas, which occupy structural space, increase the overall size, and the traditional antenna design can also block signals from the metal casing. Utility Model Content

[0003] To address the shortcomings of existing technologies, which mostly employ built-in antennas that occupy structural space and increase the overall size of the device, and the fact that traditional antenna designs often shield signals with metal casings, this invention provides a smartwatch with a metal casing that serves as the GPS antenna.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a smartwatch with a metal casing serving as a GPS antenna, comprising a bottom casing, a watch motherboard inside the bottom casing, a metal cover for acting as an antenna fixed on the upper surface of the bottom casing, a display screen connected to the watch motherboard mounted on the metal cover, multiple antenna feed points on the watch motherboard, and multiple conductive springs welded to each antenna feed point for contacting the metal cover after the bottom casing and the metal cover are assembled, the metal cover being made of the same metal material used for making antennas.

[0006] As a preferred embodiment of this utility model, the bottom shell and the metal cover are fixed together by fastening screws.

[0007] As a preferred embodiment of the present invention, the conductive spring includes a solder base welded to the antenna feed point, the solder base having an S-shaped flexed spring body, the front end of the spring body having an outwardly inclined connecting piece, and the end of the connecting piece having a contact portion that is bent inward and in contact with a metal cover.

[0008] As a preferred embodiment of this utility model, the welding base is provided with a contact piece that abuts against the end of the spring body, and the contact piece is in the shape of a door.

[0009] As a preferred embodiment of this utility model, the antenna feed point is provided with no less than 3 points.

[0010] As a preferred technical solution of this utility model, the bottom shell is provided with a storage groove for storing the metal cover.

[0011] The beneficial effects of this utility model are:

[0012] This type of smartwatch with a metal casing as its GPS antenna utilizes the metal faceplate as the antenna for the watch's mainboard. This eliminates the need for a separate antenna, saving space and promoting the miniaturization of the smartwatch. Furthermore, it avoids the internal antenna being easily blocked by the metal casing. The watch's mainboard has multiple antenna feed points, each of which is welded with multiple conductive springs that make contact with the metal faceplate after the bottom shell and the metal faceplate are assembled, facilitating assembly.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example: Figure 1 , Figure 2 , Figure 3As shown, this utility model discloses a smartwatch with a metal casing serving as a GPS antenna. It includes a bottom case 1, within which a mainboard 2 is housed. A metal cover 3, acting as an antenna, is fixed to the upper surface of the bottom case 1. A display screen 13, connected to the mainboard 2, is mounted on the metal cover 3. The mainboard 2 has multiple antenna feed points 4, each with multiple conductive springs 5 ​​welded to it for contact with the metal cover 3 after the bottom case 1 and the metal cover 3 are assembled. The metal cover 3 is made of the same metal material used for antenna fabrication. Using the metal cover 3 as the antenna for the mainboard 2 eliminates the need for a separate antenna, saving space and promoting smartwatch miniaturization. Furthermore, it avoids the internal antenna being easily blocked by the metal casing. The multiple antenna feed points 4 on the mainboard 2, each with multiple conductive springs 5 ​​welded to it for contact with the metal cover 3 after the bottom case 1 and the metal cover 3 are assembled, facilitates assembly. The use of a metal outer frame ensures the antenna signal is transmitted smoothly; the glossy metal material provides a pleasant feel and meets users' aesthetic requirements. The metal bezel and other metal parts of the watch are also among the best materials we can utilize as antenna receivers. The assembly method of the watch motherboard 2 is as follows... Figure 4 As shown.

[0021] The bottom shell 1 and the metal cover 3 are fixed together by fastening screws 12, which facilitates installation and disassembly.

[0022] The conductive spring 5 includes a solder base 6 welded to the antenna feed point 4. The solder base 6 has an S-shaped curved spring body 7. The front end of the spring body 7 has an outwardly tilted connecting piece 8. The end of the connecting piece 8 has an inwardly bent and inverted contact portion 9 that contacts the metal cover. By setting a specific conductive spring, in which the connecting piece is outwardly flared, it is convenient for the contact portion 9 to align with the frame of the metal cover. When aligned, the contact portion is firmly in contact with the metal cover under the elastic action of the connecting piece, and poor contact is less likely to occur.

[0023] The welding base 6 is provided with a contact piece 10 that abuts against the end of the spring body 7. The contact piece 10 is in the shape of a door, which increases the overall stability.

[0024] The multiple antenna feed points 4 are arranged in a ring on the mainboard 2 of the watch, which avoids poor signal due to poor contact of a single antenna feed point. There are no fewer than three antenna feed points 4.

[0025] The bottom shell 1 is provided with a storage groove 11 for storing the metal cover 3, which facilitates the installation between the bottom shell 1 and the metal cover 3.

[0026] When in operation, this type of smartwatch with a metal casing as its GPS antenna uses the metal faceplate 3 as the antenna for the watch motherboard 2. This eliminates the need for a separate antenna, thus saving space and promoting the miniaturization of the smartwatch. Furthermore, the built-in antenna is easily shielded by the metal casing material. The watch motherboard 2 has multiple antenna feed points 4, and each antenna feed point 4 has multiple conductive springs 5 ​​welded on it for contact with the metal faceplate 3 after the bottom shell 1 and the metal faceplate 3 are assembled. This facilitates assembly.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
