The first metal connection part 400 may be disposed in parallel with the first antenna 101 and the second antenna 102. For example, the first antenna 101 may be disposed on a side of the first metal connection part 400 close to a display surface (e.g., a display surface of the display screen 600) of the wearable electronic device 10 (an upper side of the first metal connection part 400), and the second antenna 102 may be disposed on a side of the first metal connection part 400 away from the display surface of the wearable electronic device 10 (a lower side of the first metal connection part 400).

For example, the first metal connection part 400 may be disposed parallel to the display surface of the wearable electronic device 10, the first antenna 101 is disposed on one side of the first metal connection part 400 (e.g., the left side of the first metal connection part 400) perpendicular to the display surface, and the second antenna 102 is disposed on the other side of the first metal connection part 400 (e.g., the right side of the first metal connection part 400) perpendicular to the display surface.
In the embodiment of the present application, the first antenna 101 and the second antenna 102 are vertically disposed relative to the first metal connecting portion 400, on one hand, the first antenna 101 and the second antenna 102 may not occupy the thickness of the bezel 200, and accordingly, the thickness of the first metal connecting portion 400 may be close to the thickness of the bezel 200, and the connection between the first metal connecting portion 400 and the bezel 200 and the midplane 100 is more reliable; on the other hand, the first metal connecting portion 400 may also maximally block the wireless signal transmitted by the first antenna 101 from being diffracted to the area where the second antenna 102 is located, and may also maximally block the wireless signal transmitted by the second antenna 102 from being diffracted to the area where the first antenna 101 is located, thereby reducing the interference between the first antenna 101 and the second antenna 102.
It should be noted that the positional relationship among the first antenna 101, the second antenna 102, and the first metal connection 400 is not limited to the above-mentioned parallel or vertical arrangement, for example, the first antenna 101 and the second antenna 102 may be obliquely arranged on both sides of the first metal connection 400; or, an included angle between the first antenna 101 and the first metal connection 400 is a first angle, and an included angle between the second antenna 102 and the first metal connection 400 is a second angle, where the first angle is different from the second angle. The present embodiment does not limit the positional relationship between the first antenna 101, the second antenna 102, and the first metal connection 400, and any scheme that satisfies the requirement that the first metal connection 400 is disposed between the first antenna 101 and the second antenna 102 and improves the isolation between the first antenna 101 and the second antenna 102 is within the scope of the present embodiment.

For example, the second metal connecting portion 800 may include a metal shaft parallel to the middle plate 100, two lugs may be oppositely disposed on the second side surface 220 of the middle plate 100 or the frame 200, two limiting holes may be disposed on the two lugs, and two ends of the metal shaft are located in the limiting holes and can rotate relative to the limiting holes, so as to achieve the movable connection between the second metal connecting portion 800 and the middle plate 100.
The second metal connecting part 800 may also be fixedly connected to the middle plate 100. For example, the second metal connecting portion 800 may be a boss on the second side surface 220, or the second metal connecting portion 800 may be an extension of the middle plate 100 protruding from the second side surface 220.
It should be noted that the structure of the second metal connection portion 800 is not limited to the structure of the metal rotation shaft, for example, the shape and the structure of the second metal connection portion 800 are not specifically limited in the embodiments of the present application.
One end of the second connecting portion 320 of the wearing portion 300 can be movably/fixedly connected to the second metal connecting portion 800, and then the wearable electronic device 10 can be fixed to an external object through the cooperation of the first metal connecting portion 400, the first connecting portion 310, the second metal connecting portion 800 and the second connecting portion 320.
Wherein the second metal connection part 800 may be disposed in parallel with the third antenna 103 and the fourth antenna 104. For example, the third antenna 103 may be disposed on the side of the second metal connection part 800 close to the display surface of the wearable electronic device 10 (e.g., on the side above the second metal connection part 800), and the fourth antenna 104 may be disposed on the side of the second metal connection part 800 far from the display surface of the wearable electronic device 10 (e.g., on the side below the second metal connection part 800).
In the embodiment of the application, the third antenna 103 and the fourth antenna 104 are arranged in parallel with respect to the second metal connecting portion 800, on one hand, the lengths of the second metal connecting portion 800, the third antenna 103 and the fourth antenna 104 can be close to the length of the second side surface 220 of the frame 200, and the ranges of wireless signals that can be transmitted by the third antenna 103 and the fourth antenna 104 are wider; on the other hand, the second metal connecting portion 800 can maximally block the wireless signal transmitted by the third antenna 103 from being diffracted to the area where the fourth antenna 104 is located, and can also maximally block the wireless signal transmitted by the fourth antenna 104 from being diffracted to the area where the third antenna 103 is located, thereby reducing the interference between the third antenna 103 and the fourth antenna 104.
It is understood that the arrangement positions of the third antenna 103 and the fourth antenna 104 can be interchanged, that is, the third antenna 103 is arranged on the side of the second metal connecting part 800 close to the display surface of the wearable electronic device 10, and the fourth antenna 104 is arranged on the side of the second metal connecting part 800 far from the display surface of the wearable electronic device 10.
The second metal connection 800 may be perpendicular to the third antenna 103 and the fourth antenna 104. For example, the second metal connection part 800 may be disposed parallel to the display surface of the wearable electronic device 10, the third antenna 103 is disposed on one side of the second metal connection part 800 (e.g., the left side of the second metal connection part 800) perpendicular to the display surface, and the fourth antenna 104 is disposed on the other side of the second metal connection part 800 (e.g., the right side of the second metal connection part 800) perpendicular to the display surface.
In the embodiment of the present application, the third antenna 103 and the fourth antenna 104 are vertically disposed relative to the second metal connecting portion 800, on one hand, the third antenna 103 and the fourth antenna 104 may not occupy the thickness of the frame 200, and correspondingly, the thickness of the second metal connecting portion 800 may be close to the thickness of the frame 200, so that the connection between the second metal connecting portion 800 and the frame 200 and the midplane 100 is more reliable; on the other hand, the second metal connecting portion 800 may also maximally block the wireless signal transmitted by the third antenna 103 from being diffracted to the area where the fourth antenna 104 is located, and may also maximally block the wireless signal transmitted by the fourth antenna 104 from being diffracted to the area where the third antenna 103 is located, thereby reducing the interference between the third antenna 103 and the fourth antenna 104.
The positional relationship among the third antenna 103, the fourth antenna 104, and the second metal connection 800 is not limited to the above-mentioned parallel or vertical arrangement, for example, the third antenna 103 and the fourth antenna 104 may be obliquely arranged on both sides of the second metal connection 800; or, an included angle of a first angle is formed between the third antenna 103 and the second metal connecting portion 800, and an included angle of a second angle is formed between the fourth antenna 104 and the second metal connecting portion 800, where the first angle is different from the second angle. The positional relationship among the third antenna 103, the fourth antenna 104 and the second metal connecting portion 800 is not limited in the embodiments of the present application, and any scheme that satisfies the requirement that the second metal connecting portion 800 is disposed between the third antenna 103 and the fourth antenna 104 and improves the isolation between the third antenna 103 and the fourth antenna 104 is within the scope of the embodiments of the present application.
The first metal connecting portion 400 and the second metal connecting portion 800 may be disposed in parallel, for example, the first metal connecting portion 400 and the second metal connecting portion 800 are both disposed in parallel to the display surface, or the first metal connecting portion 400 and the second metal connecting portion 800 are both disposed perpendicular to the display surface. The first metal connecting portion 400 and the second metal connecting portion 800 may also be disposed non-parallel, for example, the first metal connecting portion 400 is disposed parallel to the display surface, and the second metal connecting portion 800 is disposed perpendicular to the display surface.
It is understood that, as the positional relationship of the first metal connection part 400 and the second metal connection part 800 changes, the positional relationship of the first antenna 101, the second antenna 102, the third antenna 103 and the fourth antenna 104 also changes.
When the first antenna 101 and the third antenna 103 are located on the same side of the middle plate 100, the first antenna 101 and the third antenna 103 may be used to transmit wireless signals of different frequency bands, so as to reduce interference between the first antenna 101 and the third antenna 103. When the second antenna 102 and the fourth antenna 104 are also located on the same side of the midplane 100, the second antenna 102 and the fourth antenna 104 may also be used to transmit wireless signals in different frequency bands to reduce interference between the second antenna 102 and the fourth antenna 104.
For example, first antenna 101 and third antenna 103 are located on the left side of midplane 100, and second antenna 102 and fourth antenna 104 are located on the right side of midplane 100; alternatively, first antenna 101 and third antenna 103 are located on the side of midplane 100 closer to the display surface, and second antenna 102 and fourth antenna 104 are located on the side of midplane 100 farther from the display surface.
In the above structure, since the first antenna 101 and the fourth antenna 104 are located at opposite angles, the distance between the first antenna 101 and the fourth antenna 104 is long, and the interference between the first antenna 101 and the fourth antenna 104 is not too large, the first antenna 101 and the fourth antenna 104 can be used for transmitting wireless signals of the same frequency band, so as to implement mimo transmission of the frequency band. Similarly, the second antenna 102 and the third antenna 103 are also located at opposite angles, the distance between the second antenna 102 and the third antenna 103 is also long, the interference between the two antennas is not too large, and the second antenna 102 and the third antenna 103 can also be used for transmitting wireless signals in the same frequency band, so as to implement mimo transmission in the frequency band.
The first metal connecting portion 400 and the second metal connecting portion 800 may be grounded through the middle plate 100. For example, the middle board 100 may form a common ground of the electronic device 10, and the first metal connecting portion 400 may be provided with a grounding point, the grounding point is electrically connected to the middle board 100 through a grounding spring, a grounding wire, and the like, so as to realize grounding of the first metal connecting portion 400. The second metal connecting portion 800 may also be provided with a grounding point, and the grounding point is electrically connected to the middle plate 100 through a grounding spring, a grounding wire, and the like, so as to realize grounding of the second metal connecting portion 800.
As shown in fig. 3, a ground point may be disposed on the first metal connecting portion 400. As shown in fig. 4, two grounding points may be disposed on the first metal connecting portion 400 to further improve the isolation effect of the first metal connecting portion 400. For example, two grounding points are respectively disposed at two opposite end portions of the first metal connecting portion 400, and further, the wireless signal transmitted by the first antenna 101 is not easily diffracted from the two end portions to the area where the second antenna 102 is located, and the wireless signal transmitted by the second antenna 102 is also not easily diffracted from the two end portions to the area where the first antenna 101 is located, so that mutual interference between the first antenna 101 and the second antenna 102 is reduced.
Similarly, one grounding point may be disposed on the second metal connecting portion 800, and two grounding points may be disposed on the second metal connecting portion 800, so as to further improve the isolation effect of the second metal connecting portion 800 and reduce the mutual interference between the third antenna 103 and the fourth antenna 104.
It is understood that the first metal connecting portion 400 and the second metal connecting portion 800 of the embodiment of the present application may also be grounded in other manners, for example, the first metal connecting portion 400 may be grounded to the circuit board, the rear cover 500, or even other portions of the bezel 200, and the second metal connecting portion 800 may also be grounded to the circuit board, the rear cover 500, or even other portions of the bezel 200.

It is understood that at least two of the first antenna 101, the second antenna 102, the third antenna 103 and the fourth antenna 104 may be commonly connected to a radio frequency circuit to reduce power consumption of the radio frequency circuit. The first antenna 101, the second antenna 102, the third antenna 103 and the fourth antenna 104 may also be connected to different rf circuits, respectively, to achieve precise control of each antenna.
The first signal source may include a first feeding end and a first ground end, and a wireless signal is fed into the first antenna 101 from the first feeding end and then returned to ground from the first ground end to form a signal loop, so that the first antenna 101 transmits the wireless signal.

The first ground terminal, the second ground terminal, the third ground terminal, and the fourth ground terminal may be disposed on the middle plate 100, the frame 200, the rear cover 500, the circuit board, and the like. The specific locations of the feeding point and the grounding point may be selected according to the frequency bands of the wireless signals actually transmitted by the first antenna 101, the second antenna 102, the third antenna 103, and the fourth antenna 104.
Referring to fig. 3 and 4, the circuit board may further include a first tuning circuit 910, a second tuning circuit 920, a third tuning circuit (not shown), and a fourth tuning circuit (not shown). The first antenna 101 may be connected to a first tuning circuit 910, and the first tuning circuit 910 may include at least a first path and a second path, and when the first path is connected, the first antenna 101 may be configured to transmit a radio signal in one frequency band, and when the second path is connected, the first antenna 101 may be configured to transmit a radio signal in another frequency band.
The second antenna 102 may also be connected to a second tuning circuit 920, and the second tuning circuit 920 may also include at least a first path and a second path, where when the first path is connected, the second antenna 102 may be configured to transmit a radio signal in one frequency band, and when the second path is connected, the second antenna 102 may be configured to transmit a radio signal in another frequency band.

It can be understood that the first tuning circuit 910, the second tuning circuit 920, the third tuning circuit 930, and the fourth tuning circuit 940 may be implemented by using various switches and resistors and/or inductors and/or capacitors, for example, the switches in each tuning circuit may be a single-pole single-throw switch, a single-pole double-throw switch, a single-pole three-throw switch, and a single-pole four-throw switch, and the switches in each tuning circuit are respectively connected with capacitors with different capacitance values or resistors with different resistance values, so as to implement that the first antenna 101, the second antenna 102, the third antenna 103, and the fourth antenna 104 transmit more wireless signals in different frequency bands, and meet the requirements of the wearable electronic device 10 for wireless signals in multiple frequency bands.
For example, referring to fig. 6, fig. 6 is a circuit schematic diagram of the first tuning circuit shown in fig. 3 or fig. 4. Taking the example of the first antenna 101 transmitting the 5G signal as an example, the frequency band range of the 5G signal may include N78, N79, and N41. The first tuning circuit 910 may include a first path 911, a second path 912, and a third path 913. When the first via 911 is electrically connected to the first antenna 101, the first antenna 101 can transmit a 5G signal of N78 frequency band. When the second channel 912 is electrically connected to the first antenna 101, the first antenna 101 may transmit a 5G signal of N79 frequency band. When the third via 913 is electrically connected to the first antenna 101, the first antenna 101 may transmit a 5G signal of N41 frequency band. Furthermore, the first antenna 101 can meet the requirements of the wearable electronic device 10 for transmitting the N78, N79 and N41 frequency bands of 5G signals.
It can be understood that, by changing the impedance of the second antenna 102 through the second tuning circuit 920, changing the impedance of the third antenna 103 through the third tuning circuit, changing the impedance of the fourth antenna 104 through the fourth tuning circuit, and the like, the second antenna 102, the third antenna 103, and the fourth antenna 104 can also meet the requirements of the wearable electronic device 10 for different bands of 5G.
It can be understood that a plurality of first tuning circuits 910 may also be connected to the first antenna 101, and the transmission of signals in different frequency bands may be achieved through the cooperation between the plurality of first tuning circuits 910. Low-frequency wireless signals, intermediate-frequency wireless signals, high-frequency wireless signals, such as 4G signals, can be transmitted; for example, 5G signals of N78, N79 and N41 frequency bands can be transmitted; for example, GPS signals in the L1, L2, and L5 frequency bands may be transmitted.
Of course, a plurality of second tuning circuits 920 may also be connected to the second antenna 102, and the transmission of signals in different frequency bands may also be achieved through the mutual cooperation between the plurality of second tuning circuits 920.

The wearable electronic device 10 of the embodiment of the application changes the type of the switch or changes the specifications of the inductor, the resistor and the capacitor according to actual requirements, and further meets the requirements of the wearable electronic device 10 on different frequency band signals.
It should be noted that "transmitting" in the above-mentioned wireless signal transmission includes receiving a wireless signal, transmitting a wireless signal, and simultaneously receiving and transmitting a wireless signal.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a wearable electronic device according to an embodiment of the present application. The bezel 200 may further include a third side 230 and a fourth side 240 disposed oppositely, and the first side 210, the third side 230, the second side 220, and the fourth side 240 are sequentially connected to form the bezel 200 of the wearable electronic device 10 according to the embodiment of the present application.
The frame 200 may be a metal frame, and further, metal branches may be formed on the first side 210, the second side 220, the third side 230, and the fourth side 240, and the metal branches are used to transmit wireless signals, so that the wearable electronic device 10 does not need to be additionally provided with an antenna, and the space efficiency of the wearable electronic device 10 may be improved.
Specifically, the metal branch may be formed by providing a gap in a region of the first side surface 210 that does not overlap with the first antenna 101, the second antenna 102, and the first metal connection portion 400. A metal branch may be formed by providing a gap in a region of the second side surface 220 that does not overlap with the third antenna 103, the fourth antenna 104, and the second metal connection portion 800.
It is understood that, in order to increase the distance between the first antenna 101, the second antenna 102, the third antenna 103, the fourth antenna 104 and the metal stub and reduce the interference between the first antenna 101, the second antenna 102, the third antenna 103, the fourth antenna 104 and the metal stub, the metal stub may be formed on the third side 230 and the fourth side 240.
Taking the third side 230 as an example, a first slit 201 may be provided at an edge of the third side 230 of the bezel 200 connected to the rear cover 500, and a second slit 202 may be provided on the bezel 200, the second slit 202 dividing the third side 230 into two independent first and second portions. When the first slot 201 and the second slot 202 are communicated, a first portion communicated with the first slot 201 has a free end, the first portion may form a first metal branch 250, and the first metal branch 250 may be used to transmit a wireless signal.
To improve the utilization of the second portion of the bezel 200, the first slit 201 may extend in the opposite direction, such that the second portion also has a free end. Specifically, a third gap 203 may be further disposed at an edge of the third side 230 and the rear cover 500, an extending direction of the third gap 203 is opposite to that of the first gap 201, the third gap 203 is communicated with the second gap 202, so that the second portion may also form a free end, the second portion may form a second metal branch 260, and the second metal branch 260 may also be used to transmit a wireless signal.
It is understood that, in order to ensure the structural stability of the wearable electronic device 10, the first gap 201 and the third gap 203 may be filled with a non-metallic material, so that the bezel 200 and the rear cover 500 are completely connected. To improve the integrity of the appearance of the wearable electronic device 10, the second gap 202 may be filled with a non-metallic material that is color-matched to the appearance of the bezel 200.
In the wearable electronic device 10 of the embodiment of the application, the first gap 201, the second gap 202 and the third gap 203 are formed at the edges of the frame 200, the frame 200 and the rear cover 500, so that the first metal branch 250 and the second metal branch 260 can be formed on the frame 200, and on one hand, the first metal branch 250 and the second metal branch 260 share the second gap 202, so that the number of slits on the frame 200 is small, and the processing and the structural strength of the frame 200 are guaranteed; on the other hand, in the limited internal space, the frame 200 realizes multiplexing, does not occupy extra space of the wearable electronic device 10, and can simplify the structure of the wearable electronic device 10.
Moreover, when the side of the frame 200 where the first metal branch 250 and the second metal branch 260 are located is not the same side as the side of the frame 200 where the first antenna 101 and the second antenna 102 are located, the distance between the first antenna 101 and the first metal branch 250 and the second metal branch 260 is longer, and the isolation between the first antenna 101 and the first metal branch 250 and the second metal branch 260 is larger. The distance between the second antenna 102 and the first metal branch 250 and the second metal branch 260 is also longer, and the isolation between the second antenna 102 and the first metal branch 250 and the second metal branch 260 is also larger.
Similarly, when the side of the frame 200 where the first metal branch 250 and the second metal branch 260 are located is not the same side as the side of the frame 200 where the third antenna 103 and the fourth antenna 104 are located, the distance between the third antenna 103 and the first metal branch 250 and the second metal branch 260 is longer, and the isolation between the third antenna 103 and the first metal branch 250 and the second metal branch 260 is larger. The distance between the fourth antenna 104 and the first metal branch 250 and the second metal branch 260 is also longer, and the isolation between the fourth antenna 104 and the first metal branch 250 and the second metal branch 260 is also larger.
Because the first metal branch 250 and the second metal branch 260 share the second gap 202 in the forming process, the free end of the first metal branch 250 is opposite to the free end of the second metal branch 260, and the interference between the first metal branch 250 and the second metal branch 260 is large. In practical application, the isolation between the first metal branch 250 and the second metal branch 260 can be improved by adjusting the impedance between the first metal branch 250 and the second metal branch 260.
Of course, in practical application, an isolating member 900 may be disposed between the first metal branch 250 and the second metal branch 260, and the isolating degree between the first metal branch 250 and the second metal branch 260 is improved by grounding the isolating member 900, so as to reduce the interference between the first metal branch 250 and the second metal branch 260.
Specifically, the size of the spacer 900 may be adapted to the size of the second gap 202, so as to completely block the wireless signal transmitted by the first metal branch 250 from being diffracted to the area where the second metal branch 260 is located, and also completely block the wireless signal transmitted by the second metal branch 260 from being diffracted to the area where the first metal branch 250 is located.
