The second connection portion 800, the third antenna 103, and the fourth antenna 104 may be disposed on the second side surface 220. The second connection portion 800 is located between the third antenna 103 and the fourth antenna 104, and the second connection portion 800 is grounded to improve isolation between the third antenna 103 and the fourth antenna 104.

In the wearable electronic device 10 of the embodiment of the application, the first antenna 101 and the second antenna 102 are disposed on the first side surface 210 of the frame 200, and the third antenna 103 and the fourth antenna 104 are disposed on the second side surface 220 of the frame 200, because the first side surface 210 and the second side surface 220 are disposed oppositely, further, the distance between the first antenna 101 and the third antenna 103, and the distance between the fourth antenna 104 are relatively long, and the interference between the first antenna 101 and the third antenna 103, and between the first antenna 101 and the fourth antenna 104 is relatively small; the second antenna 102 is far away from the third antenna 103 and the fourth antenna 104, and the second antenna 102 is less interfered with the third antenna 103 and the fourth antenna 104, so that the performances of the first antenna 101, the second antenna 102, the third antenna 103 and the fourth antenna 104 can be improved.

In the wearable electronic device 10 of the embodiment of the present application, the second connecting portion 800 is connected to the middle plate 100 and the wearing portion 300 at the same time, and the second connecting portion 800 serves as a connecting member to connect the wearing portion 300 and the middle plate 100 into a whole; meanwhile, the second connection portion 800 is disposed between the third antenna 103 and the fourth antenna 104, and when the second connection portion 800 is grounded, the second connection portion 800 serves as a spacer, so that interference between the third antenna 103 and the fourth antenna 104 can be reduced. In the wearable electronic device 10 of the embodiment of the application, on one hand, the second connection portion 800 serves as a connection member and a separation member at the same time, so that multiplexing is realized, and the internal structure of the wearable electronic device 10 can be simplified; on the other hand, the isolation between the third antenna 103 and the fourth antenna 104 is large, so that the mutual interference between the third antenna 103 and the fourth antenna 104 can be reduced, the performance of the antennas is improved, and the stability of communication can be ensured.

The position relationship between the second connection portion 800 and the third and

fourth antennas

103 and 104 can also refer to the position relationship between the first connection portion 700 and the first and

second antennas

101 and 102, which is not described herein again.

The first connection portion 700 and the second connection portion 800 may be disposed in parallel, for example, the first connection portion 700 and the second connection portion 800 are disposed in parallel to the display surface, or the first connection portion 700 and the second connection portion 800 are disposed perpendicular to the display surface. The first connection portion 700 and the second connection portion 800 may also be disposed non-parallel, for example, the first connection portion 700 is disposed parallel to the display surface, and the second connection portion 800 is disposed perpendicular to the display surface.

It is understood that, as the positional relationship of the first connection portion 700 and the second connection portion 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 connection portion 700 and the second connection 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 connection portion 700 may be provided with a ground point, which is electrically connected to the middle board 100 through a ground spring, a ground wire, and the like, so as to realize the grounding of the first connection portion 700. The second 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 connecting portion 800.

As shown in fig. 7, a ground point may be disposed on the first connection portion 700. As shown in fig. 6, two grounding points may be disposed on the first connection portion 700 to further improve the isolation effect of the first connection portion 700. For example, one grounding point is disposed at each of two opposite end portions of the first connection portion 700, 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 connecting portion 800, and two grounding points may be disposed on the second connecting portion 800, so as to further improve the isolation effect of the second connecting portion 800 and reduce the mutual interference between the third antenna 103 and the fourth antenna 104.

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, the second ground, the third ground, and the fourth ground may be disposed on the middle plate 100, the frame 200, the rear cover 400, the circuit board 110, 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. 6 and 7, the circuit board 110 may further include a first tuning circuit 111, a second tuning circuit 112, 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 111, and the first tuning circuit 111 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 of one frequency band, and when the second path is connected, the first antenna 101 may be configured to transmit a radio signal of another frequency band.

The second antenna 102 may also be connected to a second tuning circuit 112, and the second tuning circuit 112 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 111, the second tuning circuit 112, the third tuning circuit 113, and the fourth tuning circuit 114 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. 9, fig. 9 is a circuit schematic diagram of the first tuning circuit shown in fig. 6 or fig. 7. Taking the first antenna 101 for 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 111 may include a first path 1111, a second path 1112, and a third path 1113. When the first path 1111 is electrically connected to the first antenna 101, the first antenna 101 may transmit a 5G signal of N78 frequency band. When the second path 1112 is electrically connected to the first antenna 101, the first antenna 101 may transmit a 5G signal of N79 band. When the third path 1113 is electrically connected to the first antenna 101, the first antenna 101 can transmit a 5G signal of N41 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 112, 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 111 may also be connected to the first antenna 101, and transmission of signals in different frequency bands may be achieved through cooperation between the plurality of first tuning circuits 111. 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; further, for example, GPS signals of the L1, L2 and L5 frequency bands may be transmitted.

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.

Referring to fig. 10, fig. 10 is a fifth structural schematic view 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 connection unit 700. 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 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 third slit 203 may be provided at an edge of the third side 230 of the bezel 200 connected to the rear cover 400, and a fourth slit 204 may be provided on the bezel 200, the fourth slit 204 dividing the third side 230 into two independent first and second portions. When the third slot 203 is communicated with the fourth slot 204, a first portion communicated with the third slot 203 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 wireless signals.

To improve the utilization of the second portion of the bezel 200, the third slit 203 may extend in the opposite direction, such that the second portion also has a free end. Specifically, a fifth slot 205 may be further disposed at an edge of the third side 230 and the rear cover 400, an extending direction of the fifth slot 205 is opposite to an extending direction of the third slot 203, the fifth slot 205 is communicated with the fourth slot 204, 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 third gap 203 and the fifth gap 205 may be filled with a non-metallic material, so that the bezel 200 and the rear cover 400 are completely connected. To improve the appearance integrity of the wearable electronic device 10, the fourth gap 204 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 third gap 203, the fourth gap 204, and the fifth gap 205 are formed at the edges of the frame 200, and the rear cover 400, 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 fourth gap 204 is shared by the first metal branch 250 and the second metal branch 260, so that the number of the slots on the frame 200 is small, which is beneficial to processing and also beneficial to ensuring the structural strength of the frame 200; 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 fourth slit 204 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 fourth slit 204, 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.

The spacer 900 may be electrically connected to the midplane 100 to ground the spacer 900. One grounding point can be arranged on the isolating piece 900, and two grounding points can be arranged on the isolating piece 900, so that the isolating effect of the isolating piece 900 is further improved.

Spacer 900 may be coupled to midplane 100 to provide for securing of spacer 900. The spacer 900 may be connected to the rear cover 400, and the spacer 900 may be fixed. The fixing manner of the spacer 900 is not limited in the embodiment of the present application.

It can be understood that, in order to further reduce the interference between the first metal branch 250 and the second metal branch 260, the first metal branch 250 and the second metal branch 260 may be used to transmit wireless signals of different frequency bands.

Specifically, the rf circuit on the circuit board 110 may be electrically connected to the first metal branch 250 and the second metal branch 260, the circuit board 110 may further be provided with a fifth signal source and a sixth signal source, and the rf circuit on the circuit board 110 may feed a wireless signal into the first metal branch 250 through the fifth signal source and feed a wireless signal into the second metal branch 260 through the sixth signal source, so that the first metal branch 250 and the second metal branch 260 may transmit the wireless signal. The fifth signal source and the sixth signal source may each be configured to generate at least one of a 4G signal, a 5G signal, a WIF signal, and a GPS signal.

The fifth signal source may include a fifth feeding end and a fifth ground end, and the wireless signal is fed into the first metal stub 250 from the fifth feeding end and then returned to the ground from the fifth ground end to form a signal loop, so that the first metal stub 250 transmits the wireless signal. The sixth signal source may also include a sixth feeding end and a sixth ground end, and the wireless signal is fed into the second metal stub 260 from the sixth feeding end and then returned to the ground from the sixth ground end to form a signal loop, so that the second metal stub 260 transmits the wireless signal.

Also, the fifth ground terminal, the sixth ground terminal may be disposed on the middle plate 100, the bezel 200, the rear cover 400, the circuit board 110, and the like. The specific locations of the feeding point and the grounding point can be selected according to the frequency bands of the wireless signals actually transmitted by the first metal branch 250 and the second metal branch 260.

A fifth tuning circuit 113 and a sixth tuning circuit 114 may also be disposed on the circuit board 110. The first metal branch 250 may be connected to a fifth tuning circuit 113, and the fifth tuning circuit 113 may include at least a first path and a second path, where when the first path is connected, the first metal branch 250 may be used to transmit a wireless signal of one frequency band, and when the second path is connected, the first metal branch 250 may be used to transmit a wireless signal of another frequency band.

The second metal branch 260 may be connected to a sixth tuning circuit 114, and the sixth tuning circuit 114 may at least include a first path and a second path, where when the first path is connected, the second metal branch 260 may be used to transmit a radio signal in one frequency band, and when the second path is connected, the second metal branch 260 may be used to transmit a radio signal in another frequency band.

It can be understood that the fifth tuning circuit 113 and the sixth tuning circuit 114 can be implemented by using various switches and resistors and/or inductors and/or capacitors, for example, the switches can be single-pole single-throw switches, single-pole double-throw switches, single-pole triple-throw switches, and single-pole four-throw switches, the switches in the fifth tuning circuit 113 and the sixth tuning circuit 114 are respectively connected with capacitors with different capacitance values or resistors with different resistance values, and the impedances of the first metal branch 250 and the second metal branch 260 are changed, so that the first metal branch 250 and the second metal branch 260 transmit more wireless signals in different frequency bands, and the requirements of the wearable electronic device 10 on wireless signals in multiple frequency bands are met.

It can be understood that the first metal branch 250 may also be connected to a plurality of fifth tuning circuits 113, and transmission of signals in different frequency bands may also be achieved through mutual cooperation between the plurality of fifth tuning circuits 113. The second metal branch 260 may also be connected to a plurality of sixth tuning circuits 114, and the transmission of signals in different frequency bands may also be achieved through the mutual cooperation between the plurality of sixth tuning circuits 114.
