The wearable electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 and fig. 2, in which, fig. 1 is a cross-sectional view of a first wearable electronic device along a first direction according to an embodiment of the present application; fig. 2 is a perspective view of a first wearable electronic device provided in an embodiment of the present application. This wearing electronic equipment includes: a main body part 1, and a first belt body part 2 and a second belt body part 3 connected to both ends of the main body part 1.
Therein, the main body portion 1 houses a power feeding module 11, said power feeding module 11 comprising a tuning circuit (111 as shown in fig. 3). The first strap part 2 is internally provided with a first antenna assembly 21, one end of the first antenna assembly 21 close to the main body part 1 is connected with the grounding end 12 in the main body part 1, the first strap part 2 is provided with M holes 22, the first antenna assembly 21 comprises M first antenna branches 23 with different lengths, and the M first antenna branches 23 and the M holes 22 are arranged in a one-to-one correspondence manner. The second band body portion 3 has a second antenna assembly 31 built therein, one end of the second antenna assembly 31 close to the main body portion 1 is connected to the feed module 11, a band pin 32 is provided at a free end of the second band body portion 3, and the band pin 32 is connected to one end of the second antenna assembly 31 remote from the feed module 111.
In operation, when the tape needle 32 is inserted into a target tape hole, the tape needle 32 is conducted to a first target antenna branch corresponding to the target tape hole, the second antenna component 31 and the first antenna component 21 together form a first target antenna, and the tuning circuit 111 performs tuning according to the structural parameters of the first target antenna, wherein the target tape hole is any one of the plurality of tape holes 22; in addition, in the case where the tape needle 32 is not inserted into the tape hole 22, the second antenna component 31 constitutes a second target antenna, and the tuning circuit 111 performs tuning in accordance with the configuration parameters of the second target antenna.
It should be noted that the first direction is perpendicular to the plane of the main body portion and parallel to the extending direction of the first belt body portion 2 and the second belt body portion 3, specifically, the direction forming the cross section shown in fig. 1, and is not described herein again.
In a specific implementation, the first antenna component 21 and the second antenna component 31 may be flexible sheet metal structures, such as: a copper sheet, a Flexible Printed Circuit (FPC), etc., and the first and second antenna assemblies 21 and 31 are enclosed in a tape body portion, which may be made of a Flexible insulating material, for example: plastic, leather material, etc., so that, in use, the strap portion can be bent. In addition, as in the embodiment shown in fig. 2, M is equal to 4, and in practical applications, the number of the first antenna branches 23 may be more or less, and is not limited in particular.
In addition, the M first antenna branches 23 having different lengths may extend into the body 1 from the corresponding band holes 22, and the distances between the M band holes 22 and the body 1 are different from each other, so that the lengths of the first antenna branches 23 corresponding to the different band holes 22 are different from each other, that is, the lengths of the first antenna branches 23 corresponding to the band holes 22 farther from the body 1 are longer.
In addition, the first strap body part is provided with M strap holes 22, M first antenna branches 23 with different lengths respectively extend and leak out of the inner side wall of the corresponding strap hole 22, so that when the strap needle 32 is inserted into a target strap hole, the strap needle 32 is conducted with the first target antenna branch corresponding to the target strap hole; further, the inner wall of the hole 22 is coated with a conductive material to form a conductive layer 24, and the first antenna branch 23 may extend to the corresponding inner wall of the hole 22 to be in conduction with the conductive material coated on the inner wall of the hole 22. In this way, when the tape needle 32 is inserted into the tape hole 22, the tape needle 32 is conducted to the first target antenna branch corresponding to the target tape hole, so that the first target antenna branch and the second antenna component 31 are conducted to constitute the first target antenna, and the inner wall of the tape hole 22 is coated with the conductive material, so that the conduction performance between the tape needle 32 and the first antenna branch 23 corresponding to the tape hole 22 into which the tape needle is inserted can be enhanced, and the antenna performance of the first target antenna can be enhanced.
In addition, in a specific implementation, the main body portion includes a housing 13 and a circuit board 14 embedded in the housing 13, the ground terminal 12 and the power feeding module 11 in the main body portion 1 may be disposed on the circuit board 14 in the housing 13, and the first antenna assembly 21 and the second antenna assembly 31 penetrate through the housing 13 to be connected with the ground terminal 12 and the power feeding module 11 on the circuit board 14, respectively. In this way, the first antenna assembly 21 and the feed module 11 may be conducted through traces on the circuit board 14, where the first target antenna is a loop antenna structure, and the other first antenna branches except for the first target antenna branch may be connected to the first target antenna branch, so that the first target antenna branch and the second antenna assembly 31 constitute an antenna body of the first target antenna, and the other first antenna branches constitute a resonant branch (also referred to as a "floating branch") of the first target antenna.
Of course, it is also possible to disconnect some or all of the first antenna branches 23 in the first antenna assembly 21 from the ground, wherein, in the case that all of the first antenna branches 23 are disconnected from the ground, the first target antenna is a linear antenna structure or a tree antenna structure; in addition, the other first antenna branches except for the first target antenna branch may be made not to contact the first target antenna branch, so that the first target antenna branch and the second antenna component 31 constitute an antenna body of the first target antenna, and the other first antenna branches constitute a parasitic coupling branch of the first target antenna.
In a specific implementation, as shown in fig. 3, the tuning circuit 111 may include a plurality of operating states, and at least one of a capacitance value and an inductance value of the tuning circuit 111 is different in different operating states, and specifically, the tuning circuit 111 may include a tunable capacitor and a tunable inductor, so that adjusting the operating state of the tuning circuit 111 is implemented by adjusting the capacitance value of the tunable capacitor or adjusting the inductance value of the tunable inductor; or the tuning circuit 111 may further include a selection switch, and a free end of the selection switch is connected to a different capacitor or inductor, so that the adjustment of the operating state of the tuning circuit 111 is achieved by controlling the free end of the selection switch.
In operation, the same user often inserts the band pin 32 into the fixed band hole 22, and when the operating frequency band of wearing the electronic device changes, the tuning circuit 111 tunes according to the structural parameters of the first target antenna formed when the band pin 32 is inserted into the band hole 22, so that the first target antenna is more adaptive to the operating frequency band of wearing the electronic device. For example: the structural parameter comprises a length of the first target antenna branch.
Whereas the length of the second antenna component 31 in the first target antenna is fixed, after determining the length of the first target antenna branch, it can be determined that the length of the first target antenna is equal to the sum of the length of the first target antenna branch and the length of the second antenna component 31.
Of course, in a specific implementation, the structural parameters may also include structural parameters such as a position relationship between the coupling branch or the resonant branch of the first target antenna and the body of the first target antenna, for example: when the tape needle 32 is inserted into the target tape hole 22, the other part of the first antenna element 2 except for the target part constitutes a resonance stub of the first target antenna. As shown in fig. 7, when the first switch 4 connects the first target antenna branch to the ground terminal 12 and both the second switch 15 and the third switch 34 are connected to the second target antenna branch, one of the second switch 15 and the third switch 34 may be selectively connected to or disconnected from the other second antenna branch, where when one of the second switch 15 and the third switch 34 is connected to the other second antenna branch, the other second antenna branch constitutes a resonant branch of the first target antenna, and when the second switch 15 and the third switch 34 is disconnected from the other second antenna branch, the other second antenna branch constitutes a coupling branch of the first target antenna.
In addition, the above-mentioned working frequency range that makes first target antenna and dress electronic equipment more adapts, specifically can be: the effective length of the first target antenna is made equal to an integer multiple of the 1/2 wavelengths of the operating frequency band. Like this, can realize under the condition of first area somatic part 2 with the lock of second area somatic part 3, this wearing electronic equipment can adapt different operating frequency channels. Specifically, the tuning circuit 111 is used to tune the first target antenna to adjust the effective length of the first target antenna, for example: the 1/2 wavelength of the operating frequency of the wearable electronic device is 2mm, and the actual length of the first target antenna is 151.5mm, the tuning circuit 111 may add capacitance or inductance to the first target antenna to adjust the effective length of the first target antenna to 152 mm.
In addition, in application, when the first belt body portion 2 of the wearable electronic device is not fastened to the second belt body portion 3, the second antenna assembly 31 in the second belt body portion 3 serves as a second target antenna of the wearable electronic device, and the tuning circuit 111 is used for tuning the second target antenna, so that the second target antenna is adapted to the working frequency band of the wearable electronic device, and therefore the wearable electronic device can still be adapted to different working frequency bands when the first belt body portion 2 is not fastened to the second belt body portion 3.
When the first band part 2 and the second band part 3 are engaged with each other, the other first antenna branch 23 of the first antenna module 21 except the first target antenna branch can still be electrically connected to the antenna body of the first target antenna, so that the resonant stub of the first target antenna can be formed, and the tuning circuit 111 also performs tuning according to the structural parameters of the resonant stub; when the first and second band parts 2 and 3 are engaged with each other, the first antenna branch 23 of the first antenna element 21 other than the first target antenna branch can be parasitically coupled to the branch, and the tuning circuit 111 performs tuning in accordance with the configuration parameters of the parasitically coupled branch.
Optionally, as shown in fig. 4, a first switch 4 is further disposed in the main body portion 1, the first switch 4 includes a first end and a second end, the first end of the first switch 4 is connected to the ground terminal 12, and the second end of the first switch 4 is connected to the first target antenna branch.
In an embodiment, the first switch 4 may be a switch assembly or an M-pole M-throw switch, where, when the first switch is an M-pole M-throw switch, the M-pole M-throw switch includes M first ends and M second ends, the M first ends are connected to the ground end, the M second ends are disposed in one-to-one correspondence with the M first antenna branches, and the M second ends are connected to or disconnected from the corresponding first antenna branches.
For example: as shown in fig. 4, if M is equal to 4, the first switch 4 is a switch assembly including 4 sub-switches, a first end of each sub-switch is connected to the ground terminal 12, and second ends of the 4 sub-switches are respectively connected to the 4 first antenna branches 23 in a one-to-one correspondence manner, so that the first target antenna branch connected to the second end of the target sub-switch is connected to the ground terminal 12 when the first end and the second end of the target sub-switch are connected.
It should be noted that the operating principle of the M-pole M-throw switch is the same as that of the switch assembly, and is not described herein again. In this embodiment, the first target antenna branch can be controlled to be connected to or disconnected from the ground terminal 12 by the switch module or the M-pole M-throw switch, and the other first antenna branches except the first target antenna branch can be controlled to be connected to or disconnected from the first target antenna branch, so that the shape and structure of the first antenna module 2 are more flexible.
In another embodiment, the first switch 4 may also be a single-pole N-throw switch, a first end of which is fixedly connected to the ground terminal 12, and a second end of which is a free end, and the free end can be connected to any one of the M second antenna branches.
In this embodiment, the first target antenna branch is connected to the ground terminal 12 by controlling the on/off state of the first switch 4, thereby simplifying the switching process of the first target antenna branch.
Optionally, as shown in fig. 5 or fig. 6, the second antenna assembly 3 includes N second antenna branches 33 with different lengths, ends of the N second antenna branches 33 with different lengths, which are far away from the main body portion 1, are connected to the strip pin 32, and an end, close to the main body portion 1, of a second target antenna branch of the N second antenna branches 33 with different lengths is connected to the tuning circuit 111, where N is an integer greater than 1, and the second target antenna branch is any one of the N second antenna branches 33 with different lengths.
In a specific implementation, the other second antenna branches 33 except the second target antenna branch among the N second antenna branches 33 with different lengths may be connected to or disconnected from the second target antenna branch, where when the other second antenna branches 33 are connected to the second target antenna branch, if the tape needle 32 is inserted into the target tape hole, the second target antenna branch and the first target antenna branch in the first antenna assembly 2 constitute a body of the first target antenna, and the other second antenna branches 33 constitute a resonant branch of the first target antenna; in the case where the other second antenna branch 33 is disconnected from the second target antenna branch, when the tape needle 32 is inserted into the target tape hole, the second target antenna branch and the first target antenna branch in the first antenna element 2 constitute a main body of the first target antenna, and the other second antenna branch 33 constitutes a resonant branch of the first target antenna.
Similarly, if the tape needle 32 is not inserted into the tape hole, the second target antenna branch constitutes a main body of the second target antenna and the other second antenna branch 33 constitutes a resonant branch of the second target antenna when the other second antenna branch 33 is connected to the second target antenna branch; in case the other second antenna branch 33 is disconnected from the second target antenna branch, the second target antenna branch constitutes a body of the second target antenna, which other second antenna branch 33 constitutes a resonant stub of the second target antenna.
In a specific implementation, as shown in fig. 5 or fig. 6, the second antenna branches 33 with different lengths may be different in the detour paths of the second antenna branches 33 in the band body portion, for example: one second antenna branch extends in a straight line and the other second antenna branch extends in an "S" shaped bend, the two second antenna branches having different lengths. Of course, in specific implementations, the second antenna branches may have any structure such as a straight line, an arc line, a bent line, etc., and the specific shape of each second antenna branch is not limited herein.
In addition, in a specific implementation, in a case that the first belt body portion is fastened to the second belt body portion, one second antenna branch most suitable for the working frequency band may be selected from the N second antenna branches 33 with different lengths according to the working frequency band of the wearable electronic device as the second target antenna branch, and the second target antenna branch and the tuning circuit 111 are communicated, so that the tuning circuit 111 tunes the antenna body formed by the second target antenna branch and the first target antenna branch in the first antenna assembly 21, and the antenna performance of the first target antenna is improved.
