Embodiment 2

[0051] This embodiment adds a compatible design to the NFC antenna function on the basis of Embodiment 1, such as Figure 9 As shown, after the user wears the smart watch and fastens the first metal buckle 731 and the second metal buckle 732, the conduction with the NFC chip 702 through the switch 703 and the metal wire 77 are connected to the independent reference ground part in the first embodiment , through the reference ground metal wire in the coaxial line 78, the reference ground of the main board is grounded, thereby forming a complete NFC of NFC chip 702-switch 703-metal wire 77-independent reference ground-reference ground metal wire of coaxial line 78-ground The antenna loop realizes the compatible design of the NFC antenna. In order not to affect the full-network performance of the antenna, when the NFC antenna is in use, the full-network antenna is controlled not to work.

Embodiment 3

[0053] like Figure 10 In the smart watch shown, the first wristband 91 is provided with an antenna main body wiring part 94 and an antenna main body wiring part reference ground 75, a coaxial line 98 is connected to the signal source 901 in the smart watch main body 90, and its feeder is connected to the antenna main body The wiring part 74, the reference ground wire of the coaxial line 48 is connected to the reference ground 95 of the main antenna wiring part; the main antenna wiring part 94 is connected to the first metal buckle 931; the second wristband 92 is provided with an auxiliary wiring part of the antenna 96, which is connected to the second metal buckle 932. In this embodiment, the first metal buckle 931 and the second metal buckle 932 are respectively a metal buckle and a metal hole of the buckle. The antenna main wiring part 94 is a multi-branch wiring form, which is divided into low-frequency, intermediate-frequency and high-frequency branches. The reference gr...

Abstract

The present invention discloses an antenna of an intelligent wrist wearing device and the intelligent wrist wearing device. According to the present invention, an antenna main body routing part and an antenna auxiliary routing part are respectively arranged on a first wrist band and a second wrist band of the intelligent wrist wearing device, by buckling a first metal buckle and a second metal buckle which are connected with the tail ends of the two wrist bands respectively, the antenna main body routing part and the antenna auxiliary routing part which are arranged on the two wrist bands are connected electrically, and the antenna main body routing part is connected with a signal source arranged inside the main body of the intelligent wrist wearing device via a coaxial line, thereby realizing the reconstruction of the antenna after a user wears the intelligent wrist wearing device and buckles the first and second metal buckles. By the reconstruction, the technical effect of improving the performance of the original antenna or expanding the radiation frequency band of the original antenna can be realized based on different implementation modes of increasing the radiation area of the original antenna, increasing the branches of the original antenna, increasing the independent reference ground of the antenna, etc., and the compatible design of the antennas, such as the FM antenna, the NFC antenna, the WPC antenna, etc., also can be realized.

Description

technical field [0001] The invention belongs to the technical field of antenna design, and in particular relates to an antenna of a smart wrist-worn device and the smart wrist-worn device. Background technique [0002] With the good market popularity and good market prospects of smart wrist-worn devices, such as smart watches and smart bracelets, their compatible functions are also becoming more diversified, not limited to simple functions such as timing and step counting. [0003] The existing smart wrist-worn devices take smart watches as the mainstream, and have developed from the initial Bluetooth communication function to multi-functional integration of 2G, 3G, 4G full Netcom call and data connection functions, GPS functions, WIFI functions and NFC functions. [0004] The design of all-netcom antennas, especially in the design of low-frequency antennas including 800MHZ and 900MHZ, has certain requirements for antenna design space, and smart wrist-worn devices have limit...
