[0002] Smart watches are a commonly used communication device in modern life. They can facilitate people’s daily communication needs and bring convenience to people’s daily lives.

[0003] In order to improve the wearer's usability, existing smart watches tend to be designed with ultra-thin structures, and the ultra-thin structure needs to be achieved through the structure of the mainboard and the layout of parts. The existing mainboard is relatively thick, and some parts are not dispersedly arranged, overlapping with the battery, resulting in the inability to reduce the overall thickness of the mainboard. In addition, in the watch structure for ejecting the card, the SIM card needs to be installed and removed by pressing, but due to the lack of corresponding avoidance holes on the mainboard, the position where the SIM card fits the mainboard will interfere with the finger or the pressing tool when pressing, and the mainboard is usually designed to be flush at the connection position between the card tray and the mainboard. When the card tray is turned over, the bottom is easy to interfere with the mainboard, especially after a long period of use, after the card and the card tray are deformed to a certain extent due to pressure, the interference will be more obvious, which will cause damage to the mainboard and affect subsequent use.

[0023] See also Figure 1 - Figure 5 As shown, the technical solution adopted in this specific implementation is: it includes a PCB main board 8, a shielding cover 19 is arranged on the front of the PCB main board 8, the top two sides of the shielding cover 19 are avoided inward, a first antenna shrapnel 1 is arranged on one side and connected to the PCB main board 8, the first antenna shrapnel is a 4G antenna shrapnel, a screen assembly BTB connector 3 is arranged on the other side and connected to the PCB main board 8, a shielding cover window 6 is arranged on one side of the middle part of the shielding cover 19, and the shielding cover can shield the interference of external signals on internal electronic components, and it is also a protection for the original parts, so that the main board as a whole is more neat after the original parts are installed;

[0024] A SIM card holder 2 is provided on one side of the middle of the front side of the PCB main board 8, and a relief groove 801 is provided on one side of the middle of the back side of the PCB main board 8 corresponding to the SIM card holder 2. In the existing structure, there is usually no relief groove provided at the card holder position. During the card insertion or removal process, fingernails or tools interfere with and rub against the main board, causing wear on the main board. Therefore, a relief groove is provided in this embodiment, so that the SIM card no longer contacts the main board position during the insertion and removal process, thereby preventing friction with the main board and causing damage to the main board;

[0025] The side opposite to the avoidance groove 801 protrudes outward to form a welding plate structure, on which the first microphone welding pad 4 and the first motor welding pad 5 are arranged. The bottom of the PCB main board 8 extends to the right in a semi-arc shape, on which the first antenna 7 is arranged, and the first antenna is a GPS / WIFI / Bluetooth antenna. A third antenna shrapnel 12 is arranged on the back of the first antenna 7, and the third antenna shrapnel is a GPS / WIFI / Bluetooth antenna shrapnel. In this embodiment, a plurality of protruding welding plate structures are arranged on the edge of the main board, and the welding points of the components are welded on the welding plate, which not only facilitates the welding operation, but also reduces the thickness of the main board, and also facilitates the limiting installation of the main board.

[0026] To be more specific, a second antenna spring 18 is arranged at a position on the top of the back side of the PCB mainboard 8 corresponding to the first antenna spring 1, and the second antenna spring 18 is also a 4G antenna spring.

[0027] More specifically, a second microphone pad 9 and a second motor pad 10 are disposed on the back side of the first microphone pad 4 and the first motor pad 5 correspondingly.

[0028] More specifically, a key FPC pad 11 is disposed inside the second motor pad 10 .

[0029] More specifically, an extended FPC pad 14 is provided opposite to the key FPC pad 11 .

[0030] To be more specific, a speaker pad 15 is disposed on the outer side below the extended FPC pad 14 , and the speaker pad 15 is disposed at an arc-shaped position extending outward from the PCB main board 8 .

[0031] To be more specific, a heart rate / button FPC connector 13 and a camera FPC connector 17 are provided at the bottom of the mainboard.

[0032] More specifically, a battery pad 16 is provided on one side of the camera FPC connector 17 .

[0033] More specifically, the area between the key FPC pad 11 and the extension FPC pad 14 is the battery installation area.

[0034] More specifically, the PCB main board 8 is 38.5 mm in length, 32.83 mm in width and 0.8 mm in thickness. In this example, by arranging components around the main board, the length, width and thickness of the main board are effectively reduced.

[0035] The working principle of the utility model is: multiple component welding areas are set around the mainboard, and are protruding parts set around the mainboard. The original part is mainly installed on the front of the mainboard and covered by a shielding cover to separate the installation area from the welding area, which can effectively reduce the overall thickness. At the same time, an avoidance groove is set at the corresponding card slot position of the mainboard. When inserting or removing the card, fingernails or other tools will not interfere with the mainboard, which makes it more convenient to take out or insert the card and reduces damage to the mainboard. By moving the Jianghan block outward, the overall volume of the mainboard is smaller, which is more conducive to the miniaturization design of the watch.

[0036] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
