The wearable electronic device includes: a main body part 1 and a first belt body part 2 and a second belt body part 3 respectively connected to both ends of the main body part 1 .

Wherein, the main body part 1 has a built-in feeding module 11 , and the feeding module 11 includes a tuning circuit (as shown in FIG. 3 , 111 ). The first belt body 2 has a built-in first antenna assembly 21 , and one end of the first antenna assembly 21 close to the main body 1 is connected to the ground terminal 12 in the main body 1 , and M belt holes 22 are provided on the first belt body 2 , the first antenna assembly 21 includes M first antenna branches 23 with different lengths, and the M first antenna branches 23 are arranged in a one-to-one correspondence with the M strip holes 22 .

During operation, when the belt needle 32 is inserted into the target belt hole, the belt needle 32 is connected to the first target antenna branch corresponding to the target belt hole, and the second antenna assembly 31 and the first antenna assembly 21 are formed together The first target antenna, the tuning circuit 111 performs tuning according to the structural parameters of the first target antenna, and the target band hole is any one of the plurality of band holes 22; In this case, the second antenna assembly 31 constitutes a second target antenna, and the tuning circuit 111 performs tuning according to the structural parameters of the second target antenna.

It should be noted that the above-mentioned first direction is perpendicular to the plane on which the main body portion is located, and is 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 . This will not be repeated here.

In a specific implementation, the first antenna assembly 21 and the second antenna assembly 31 may be flexible metal sheet structures, such as copper sheets, flexible printed circuit boards (Flexible Printed Circuit, FPC), etc., and the first antenna assembly 21 and the second antenna assembly 31 The antenna assembly 31 is wrapped in a belt body, which can be made of a flexible insulating material, such as plastic, leather material, etc., so that in use, the belt body can be bent. In addition, in the embodiment shown in FIG. 2 , M is equal to 4. In practical applications, the number of the first antenna branches 23 may be more or less, which is not specifically limited here.

In addition, the M first antenna branches 23 with different lengths can respectively extend into the main body part 1 from the corresponding strip holes 22. Since the distances between the M strip holes 22 and the main body part 1 are different from each other, the different distances from the M strip holes 22 are different from each other. The lengths of the first antenna branches 23 corresponding to the holes 22 are different from each other, that is, the lengths of the first antenna branches 23 corresponding to the holes 22 that are farther from the main body 1 are longer.

In addition, the first belt body is provided with M belt holes 22, and M first antenna branches 23 with different lengths respectively extend and leak out to the inner side walls of the corresponding belt holes 22, so that when the belt needle 32 is inserted into the target belt hole , so that the belt pin 32 is connected to the first target antenna branch corresponding to the target belt hole; further, the inner wall of the belt hole 22 is coated with a conductive material to form a conductive layer 24, and the first antenna branch 23 can be extended to the corresponding The inner wall of the belt hole 22 is in conduction with the conductive material coated on the inner wall of the belt hole 22 .

In this way, the first antenna assembly 21 can be connected to the feeding module 11 through the wiring on the circuit board 14. At this time, the first target antenna is a loop antenna structure, and the other first antenna branches except the first target antenna branch It can be connected with the first target antenna branch, so that the first target antenna branch and the second antenna assembly 31 constitute the antenna body of the first target antenna, and the other first antenna branches constitute the resonance branch of the first target antenna (also referred to as the first target antenna). "suspended branches").

Of course, some or all of the first antenna branches 23 in the first antenna assembly 21 can also be disconnected from the ground terminal, wherein, in the case where all the first antenna branches 23 are disconnected from the ground terminal, the first target antenna It is a linear antenna structure or a tree antenna structure; in addition, other first antenna branches except the first target antenna branch can also be kept out of contact with the first target antenna branch, so that the first target antenna branch and the second antenna assembly 31 constitutes the antenna body of the first target antenna, and the other first antenna branches constitute parasitic coupling branches of the first target antenna.

In a specific implementation, as shown in FIG. 3 , the tuning circuit 111 may include a plurality of working states. Under different working states, at least one of the capacitance value and the inductance value of the tuning circuit 111 is different. The circuit 111 may include an adjustable capacitor and an adjustable inductance, so that the working state of the tuning circuit 111 can be adjusted by adjusting the capacitance value of the adjustable capacitor or the inductance value of the adjustable inductor; or the tuning circuit 111 may also include a selection switch, And the free end of the selection switch is connected with different capacitors or inductances, so that the working state of the tuning circuit 111 can be adjusted by controlling the free end of the selection switch.

In addition, as shown in FIG. 7, when the first switch 4 connects the first target antenna branch with the ground terminal 12, and both the second switch 15 and the third switch 34 are connected with the second target antenna branch, the second switch 15 and the third switch 34 are connected to the second target antenna branch. One of the third switches 34 can be selectively connected to the other second antenna branches or respectively disconnected from the other second antenna branches, wherein when one of the second switch 15 and the third switch 34 is connected to the other second antenna branches , the other second antenna branch constitutes the resonance branch of the first target antenna, and when the second switch 15 and the third switch 34 are respectively disconnected from the other second antenna branch, the other second antenna branch constitutes the coupling of the first target antenna branches.

In addition, the above-mentioned making the first target antenna more suitable for the working frequency band of the wearable electronic device may specifically be: making the effective length of the first target antenna equal to an integer multiple of 1/2 wavelength of the working frequency band. In this way, it can be realized that the wearable electronic device can adapt to different working frequency bands when the first belt body 2 and the second belt body 3 are fastened together. Specifically, the tuning circuit 111 is used to tune the first target antenna to adjust the effective length of the first target antenna.
