[0023] Please see Figure 1 This utility model embodiment provides a heart rate monitoring board 100 with an extension, including: a monitoring board body 110 and a monitoring board cable 120 connected to the monitoring board body, wherein the end of the monitoring board cable away from the monitoring board body is connected to a floor extension cable 130.

[0024] This invention adds a ground extension cable 130 to the existing heart rate monitoring board. The ground extension cable 130 serves as a metal ground connection to the main board, extending the main board ground. The monitoring board cable 120 is used for normal heart rate monitoring, connecting the main board and the monitoring board body 110 to achieve normal heart rate monitoring. In other words, this application sets the heart rate monitoring board as a shared structure with both heart rate monitoring and ground extension functions, thus achieving both functions without changing the existing structure. Utilizing the internal space of the wearable device significantly improves the overall antenna performance, providing a better user experience. The ground extension cable 130 and the metal layer of the heart rate monitoring board, acting as an extended main board ground, do not affect the normal function of the heart rate monitoring board.

[0025] In a further embodiment, such as Figure 1 As shown, the monitoring board cable 120 and the floor extension cable 130 surround the periphery of the monitoring board body 110.

[0026] In this embodiment, the monitoring board cabling 120 and the ground extension cable 130 surround the periphery of the monitoring board body 110. This allows for full utilization of the peripheral space of the monitoring board body 110, while also increasing the length of the ground extension cable and improving the overall antenna performance.

[0027] In a further embodiment, such as Figure 1 As shown, the monitoring board cable 120 includes a straight monitoring cable 121 and a curved monitoring cable 122; The two ends of the monitoring straight cable 121 are connected to the monitoring plate body 110 and the monitoring curved cable 122, respectively.

[0028] The floor extension line 130 includes a straight floor cable 131 and a curved floor cable 132; One end of the floor straight cable 131 is connected to the end of the monitoring curved cable 122 away from the monitoring straight cable 121; the other end of the floor straight cable 131 is connected to the floor curved cable 132.

[0029] In this embodiment, by setting up a monitoring straight cable 121 and a monitoring curved cable 122, the overall structure surrounds the periphery of the monitoring board body 110, thereby making full use of the periphery of the monitoring board body 110. At the same time, it can increase the length of the monitoring board cable 120 and the floor extension cable 130, and can arrange the position of the monitoring board cable 120 and the floor extension cable 130 more flexibly according to the internal structure of the wearable device.

[0030] In a further embodiment, the floor straight cable 131 and the monitoring straight cable 121 are arranged symmetrically with respect to the monitoring board body 110. The floor bend cable 132 and the monitoring bend cable 122 are arranged symmetrically with respect to the monitoring plate body 110.

[0031] The above structure allows for a more effective extension of the main board ground. It also facilitates adjusting the length of the floor extension cable 130 according to actual conditions. Furthermore, it reduces the interference between the floor bend cable 132 and the monitoring bend cable 122, ensuring optimal overall performance.

[0032] See Figure 2 and Figure 3 In another embodiment, this utility model also provides a smart watch, including: the heart rate monitoring board 100 with an extended ground as described above, and further including a middle frame 200, a main board 300 disposed in the middle frame, and a main antenna unit 400 disposed on the inner side of the middle frame; the main antenna unit 400 is electrically connected to the main board 300; The motherboard 300 and the heart rate monitoring board 100 with an extended ground are electrically connected via a connector.

[0033] A watch back case 600 is provided on one side of the middle frame 200, and the heart rate monitoring board 100 with an extension is provided between the main board 300 and the watch back case 600.

[0034] On the other side of the middle frame 200, away from the watch case 600, there are also a display screen 700 and a bezel 800.

[0035] In this embodiment, the heart rate monitoring board 100 with an extended ground is connected to the motherboard 300, and the floor extension cable 130 is used as a metal ground to connect to the motherboard 300, thus extending the motherboard ground. This fully utilizes the internal space, significantly improving the antenna performance of the entire device and providing a better user experience. Furthermore, in this embodiment, the heart rate monitoring board 100 with an extended ground is positioned between the motherboard 300 and the watch case 600, and is enclosed within the entire watch device by the watch case 600, thus not affecting the overall waterproof performance of the device.

[0036] In one embodiment, an antenna bracket is provided inside the mid-frame 200, and the main antenna unit 400 is laser-engraved on the antenna bracket. This fully utilizes the internal space of the mid-frame 200 and enables support for GPS / WIFI / BT bands.

[0037] In a further embodiment, such as Figure 4 and Figure 5 As shown, the main antenna unit 400 and the main board 300 are electrically connected via an antenna pin 210.

[0038] The antenna pin 210 can be placed between the main antenna unit 400 and the motherboard 300. Relying on the elasticity of the antenna pin 210, it can be tightly placed with the main antenna unit 400. Even if vibration or other situations occur, the electrical connection between the main antenna unit 400 and the motherboard 300 can be guaranteed, thus improving the stability of the entire device.

[0039] In a further embodiment, the connector includes a BTB male connector and a BTB female connector; the BTB female connector is soldered onto the motherboard 300; as shown below. Figure 3 As shown, the BTB male seat 500 is disposed between the floor extension line 130 and the monitoring board cable 120.

[0040] In this embodiment, the connectors are BTB male and female, and both the ground plane extension cable 130 and the monitoring board cable 120 are copper-plated all-metal FPC cables. The BTB male connector 500 is positioned between the ground plane extension cable 130 and the monitoring board cable 120, allowing them to be routed in different directions for easier wiring. Furthermore, the ground plane extension cable 130 and the monitoring board cable 120 have opposite routing directions, reducing interference between them. In specific configuration, the pins at the four corners of the BTB male connector 500 are connected to the motherboard ground.

[0041] Based on the existing heart rate monitoring board, this utility model adds a floor extension cable 130. The floor extension cable 130 is used as a metal ground to connect to the main board, which serves to extend the ground of the main board. The monitoring board cable 120 is used for the normal heart rate monitoring function, which connects the main board and the monitoring board body 110 to realize the normal heart rate monitoring function.

[0042] This application configures the heart rate monitoring board as a structure that shares both heart rate monitoring and ground extension functions. This allows for full utilization of the existing structure and space without altering the existing design, simultaneously achieving both heart rate monitoring and ground extension functions. Utilizing internal space effectively significantly improves the overall antenna performance, providing a better user experience. Furthermore, the ground extension cable 130 and the metal layer of the heart rate monitoring board serve as the ground for the extended mainboard, without affecting the normal function of the heart rate monitoring board.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
