As shown in fig. 2, fig. 2 is a second partial structural schematic diagram of a wearable device provided in the embodiment of the present application. The connector link 400 may be provided with a first radiator, such as a first radiator 410 and a second radiator, such as a second radiator 420, where the first radiator 410 may be configured to receive and transmit a first radio frequency signal, the second radiator 420 may be configured to receive and transmit a second radio frequency signal, the first radio frequency signal may be the same as the second radio frequency signal, and the first radio frequency signal may also be different from the second radio frequency signal. The Radio Frequency signal (RF-Radio Frequency signal) may refer to an electromagnetic wave which is modulated and has a certain transmission Frequency.
It should be noted that the number of radiators provided on the connector link 400 is not limited to this, and for example, one radiator may be provided on the connector link 400, or two or more radiators may be provided.
The first radio frequency signal can be a Wi-Fi signal, the Wi-Fi signal is a signal which is wirelessly transmitted based on a Wi-Fi technology and is used for accessing a wireless local area network to achieve network communication, and the Wi-Fi signal comprises Wi-Fi signals with the frequencies of 2.4GHz and 5 GHz. It should be noted that the first radio frequency signal may also be other signals, for example, the first radio frequency signal may also be a GPS signal, a 3G signal, a 4G signal, or a 5G signal, or a GPS signal (Global Positioning System), and the frequency range of the GPS signal may be 1.2GHz to 1.6 GHz; the 4G signals may include a Low Band (LB), a Medium Band (MB), and a High Band (HB), wherein the LB includes a frequency range of 700MHz to 960MHz, the MB includes a frequency range of 1710MHz to 2170MHz, and the HB includes a frequency range of 2300MHz to 2690 MHz; the 5G NR (New Radio) signal may be used to access a wireless communication network to implement wireless communication, and the 5G NR signal mainly includes two frequency bands: FR1 frequency band and FR2 frequency band. The frequency range of the FR1 frequency band is 450 MHz-6 GHz, also called sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25GHz to 52.6GHz, commonly called millimeter Wave (mm Wave). The 3GPP Release 15 version specifies the current 5G millimeter wave frequency band: n257(26.5 to 29.5GHz), n258(24.25 to 27.5GHz), n261(27.5 to 28.35GHz) and n260(37 to 40 GHz). The second radio frequency signal may also be any of the signals described above.
It should be noted that, because the length of the radiator required by the low-frequency rf signal is longer, and the wearable device is generally smaller, the length of the connector link 400 may not meet the requirement of the length of the radiator of the low-frequency rf signal, and at this time, another radiator may be additionally disposed in the casing 100 for transmitting the low-frequency rf signal.
In the embodiment of the application, the first radiator 410 and the second radiator 420 are disposed on the connector link 400, compared with the case 100 on which the radiators are directly disposed, the space occupation of the radiators on the case 100 can be reduced, and the distances between the first radiator 410 and the second radiator 420 and other components disposed on the case 100 can be increased, and the headroom areas of the first radiator 410 and the second radiator 420 are increased, so that the antenna design of multiple radiators can be realized under the condition of a small antenna headroom area, the communication performance of the multiple radiators under a small headroom can be improved, and the occupation space of the multiple radiators can be reduced.
Referring to fig. 2, the connection buckle 400 may include a frame body such as the frame body 430 and a buckling portion such as the buckling portion 440, the frame body 430 may be a hollow frame structure, for example, the frame body 430 may be provided, the second wearing portion 300 may be inserted into the frame body, and the second wearing portion 300 is fixed inside the frame body through the buckling portion 440, so that the second wearing portion 300 is fixedly connected with the first wearing portion 200.
The frame 430 may have a regular shape, such as a rectangular shape or a circular shape, and the frame 430 may have an irregular shape. The frame 430 may include a first side portion, a second side portion and a third side portion connected in sequence, the first side portion is disposed opposite to the third side portion, a rotation shaft 500 is disposed between the first side portion and the third side portion, and the rotation shaft 500 is rotatably connected to the first side portion and the third side portion respectively so that the rotation shaft 500 can rotate relative to the frame 430. The engaging portion 440 is connected to the frame 430 through the rotating shaft 500, for example, the engaging portion 440 can be fixed on the rotating shaft 500, and the engaging portion 440 can rotate with the frame 430 together with the rotating shaft 500.
The first radiator 410 is disposed on the frame 430, for example, the first radiator 410 may be formed by injection molding, such as injection molding using plastic, aluminum-magnesium alloy or titanium-aluminum alloy, stainless steel, or by printing, such as printing a printed material containing a conductive material on a conductive medium, or by laser molding, such as plating directly on a plastic support by using a laser technology. The first radiator 410 may be formed of a metal such as stainless steel, a flexible circuit board, plastic, other suitable material, or a combination of any two or more of these materials.
For example, when the frame 430 is made of a metal material (such as stainless steel), a part or all of the frame 430 may be directly used as the first radiator 410; when the frame 430 is made of a non-metal material, the first radiator 410 may be printed on the frame 430 by printing, or the flexible printed circuit board may be disposed on the frame 430 and the first radiator is formed on the flexible printed circuit board; when a portion of the frame 430 is made of a metal material and a portion of the frame 430 is made of a non-metal material, the first radiator 410 may be formed on the metal section and/or the non-metal section of the frame 430 by any of the above-mentioned methods.
The second radiator 420 is disposed on the fastening portion 440, wherein the manner in which the second radiator 420 is disposed on the fastening portion 440 may be the same as the forming manner of the first radiator 410, or may be different from the forming manner of the first radiator 410.
Referring to fig. 2, the frame 430 and the fastening portion 440 are made of metal, a gap 600 is formed between the periphery of the fastening portion 440 and the frame 430, and the gap 600 is used for separating the frame 430 and the fastening portion 440, and further separating the first radiator 410 and the second radiator 420. For example, the engaging portion 440 can be accommodated therein, and the volume of the engaging portion 440 is smaller than the volume, so that the engaging portion 440 does not contact the frame 430. It can be understood that, since the frame 430 and the fastening portion 440 are both made of conductive metal, if the gap 600 is not formed between the frame 430 and the fastening portion 440, the frame 430 and the fastening portion 440 are directly contacted and conducted, and thus, the signal transceiving of the first radiator 410 and the second radiator 420 is affected.
Alternatively, a portion of the frame 430 may also be made of a non-metal material, for example, as shown in fig. 3, fig. 3 is a schematic view of a first structure of a connection buckle in the wearable device shown in fig. 2. Frame body 430 can include first metal section 431 and first non-metal section 432, first metal section 431 adopts the metal material to make, first non-metal section 432 adopts the non-metal material to make, for example can adopt separately-formed first metal section 431 and first non-metal section 433, adopt the connecting piece to connect both, or adopt the viscose to bond both together, can also adopt the mode of moulding plastics to go out first non-metal section 432 at the edge injection moulding of first metal section 431, so that first metal section 431 and first non-metal section 432 become overall structure, this mode can make the connection between first metal section 431 and the first non-metal section 432 more firm. For example, the first side portion and the third side portion may be made of a metal material to form the first metal section 431, and the second side portion is made of a non-metal material to form the first non-metal section 432.
The first radiator 410 is formed on the first metal segment 431, for example, a part or all of the first metal segment 431 may be directly formed as the first radiator 410, or may be additionally formed on the first metal segment 431 in other manners. The second radiator 420 is disposed on the fastening portion 440, for example, the fastening portion 440 can be directly used as the second radiator 420. When the first wearing portion 200 and the second wearing portion 300 are not connected, the buckling portion 440 may abut against the first nonmetal section 432, and a gap 600 is formed between the periphery of the buckling portion 440 and the first nonmetal section. For example, the length of the clasp portion 440 is equal to or slightly greater than the length of the first side portion, such that a portion of the clasp portion 440 is positioned within and a portion is positioned on the first non-metallic segment 432 (or the second side portion). The longer length of the fastening part 440 can improve the connection strength between the fastening part 440 and the second wearable part 300, and since the first nonmetal section 432 is made of nonmetal material, the signal receiving and transmitting of the first radiator 410 and the second radiator 420 are not affected even if the fastening part 440 is directly contacted with the first nonmetal section 432.
It should be noted that all of the frame 430 may also be made of a metal material, and alternatively, as shown in fig. 4, fig. 4 is a second structural schematic diagram of the connection buckle in the wearable device shown in fig. 2. Can make the partly non-metallic material that adopts of buckling part 440, for example buckling part 440 can include second metal section 441 and the non-metallic section 442 of second, second metal section 441 adopts the metal material to make, the non-metallic section 442 of second adopts the non-metallic material to make, for example can adopt the non-metallic section 442 of part shaping second metal section 441 and second, adopt the connecting piece again to connect both, or adopt the viscose to bond both together, can also adopt the mode of moulding plastics to mould plastics at the edge injection moulding of second metal section 441 out the non-metallic section 442 of second, so that second metal section 441 and the non-metallic section 442 of second become overall structure, this mode can make the connection between second metal section 441 and the non-metallic section 442 of second more firm.
The second radiator 420 is formed on the second metal segment 441, for example, a part or all of the second metal segment 441 may be directly used as the second radiator 420, or may be additionally formed on the second metal segment 441 in other manners. When the first wearable portion 200 and the second wearable portion 300 are not connected, a gap 600 is formed between the periphery of the second metal segment 441 and the frame 430 to separate the first radiator 410 and the second radiator 420, so as to ensure the signal transmission and reception of the two radiators. The second non-metallic segment 442 may abut the frame 430, such as with a portion of the second non-metallic segment 442 located inside and a portion located on the frame 430 (or the second side). Since the second non-metallic segment 442 is made of a non-metallic material, even if the second non-metallic segment 442 is directly contacted with the frame 430, the signal transmission and reception of the first radiator 410 and the second radiator 420 are not affected.
It should be noted that fig. 3 is only an example, and the first metal section 431 and the first nonmetal section 432 may be in other combination forms, for example, a portion that the frame body 430 and the buckling portion 440 will contact is set as the first nonmetal section 432, and the other portion is the first metal section 431. It can be understood that, in the embodiment of the present application, the portion where the frame 430 and the fastening portion 440 will contact is made of a non-metal material, so as to prevent the frame 430 and the fastening portion 440 from being conducted after contacting, and further affect the communication performance of the first radiator 410 and the second radiator 420. Similarly, the second metal segment 441 and the second nonmetal segment 442 can be in other combinations, and are not limited to the manner shown in fig. 4.

The first ground layer 711, the second ground layer 712 and the first conductive layer 713 may be made of metal sheets, and the first signal line 710 has a three-layer metal sheet structure, which is relatively thin and has a certain flexibility, so that the flexibility and thickness of the first wearable portion 200 are not affected by the arrangement of the first signal line 710.
