In this embodiment, there are two first through slits 1151, which are respectively located at both ends of the first antenna 120. In some embodiments, referring to fig. 3, the number of the first through slits 1151 is two, wherein one of the first through slits 1151 is in communication with the first separation slit 1152, and the other of the first through slits 1151 and the first separation slit 1152 is separated by the middle frame plate 114.

Specifically, the first through slot 1151 causes the first bezel 111 to generally form a first portion and a second portion spaced apart from each other, the first spacing slot 1152 is located between the bezel 114 and the first portion of the first bezel 111, and the first through slot 1151 communicates with the first spacing slot 1152 such that the first portion of the first bezel 111 forms the first antenna 120 generally independent of the bezel 114.

The length of the first spacing slot 1152 is substantially equal to the length of the first antenna 120. The first spacing gap 1152 is communicated with the first through gap 1151 to form the first antenna 120 on the first frame 111, and the first antenna 120 is directly exposed, so that interference of internal electronic devices on the first antenna 120 is avoided, and the strength of the first antenna 120 for receiving and transmitting Wi-Fi signals is increased. In terms of process and cost, the first antenna 120, the second antenna 130, and the third antenna 140 are formed on a metal frame, and are all made of metal, so that the process of additionally arranging the first antenna 120 on the wearable electronic device 100 can be reduced, and the production cost of the wearable electronic device 100 is reduced.

The first and second parts are for convenience of description only and are not limiting; the slit width in the figure is only a schematic width and does not represent the actual slit width; the slit length in the figure is only a schematic length and does not represent the actual slit length.

Referring to fig. 2, in the present embodiment, the second antenna 130 may also be a slot antenna having the same structure as the first antenna 120. Specifically, the first frame 111 and the middle frame plate 114 are spaced apart from each other to form a second gap 1162, the first frame 111 is provided with a second through gap 1161 penetrating through the first frame 111, and the second gap 1162 communicates with the second through gap 1161 to form the second antenna 130 on the first frame 111. In the present embodiment, there are two second through slits 1161 (fig. 2), which are located at both ends of the second antenna 130. In some embodiments, referring to fig. 3, two second through slits 1161 are provided, one of the second through slits 1161 is in communication with the second separation slit 1162, and the other second through slit 1161 is separated from the second separation slit 1162 by the middle frame plate 114.

Specifically, the second through slit 1161 causes the first bezel 111 to substantially form a third portion and a fourth portion spaced apart from each other, the second slit 1162 is located between the middle bezel 114 and the third portion of the first bezel 111, and the second through slit 1161 communicates with the second slit 1162, such that the third portion of the first bezel 111 substantially forms the second antenna 130 independent of the middle bezel 114. Meanwhile, the second through slot 1162 is communicated with the first through slot 1151, and the second through slot 1162 is communicated with the first through slot 1152, so that the second antenna 130 and the first antenna 120 are spaced from each other, and interference between the second antenna 130 and the first antenna 120 in a process of transmitting and receiving signals can be reduced.

The length of the second spacing gap 1162 is substantially the same as the length of the second antenna 130. The second through gap 1161 is communicated with the second gap 1162 to form the second antenna 130 on the first frame 111, and the second antenna 130 is directly exposed, so that interference of internal electronic devices on the second antenna 130 is avoided, and the strength of the second antenna 130 for receiving and transmitting Wi-Fi signals is increased. In terms of process and cost, the antenna formed in this way can reduce the process of additionally arranging the separate second antenna 130 on the wearable electronic device 100, and reduce the production cost of the wearable electronic device 100.

The third and fourth portions are for convenience of description only and are not limiting; the slit width in the figure is only a schematic width and does not represent the actual slit width; the slit length in the figure is only a schematic length and does not represent the actual slit length.

According to the wearable electronic device 100 provided by the embodiment of the application, by arranging the first antenna 120 and the second antenna 130, when a user holds the wearable electronic device 100 by hand and shields one of the wearable electronic device 100, the wearable electronic device 100 can receive and transmit Wi-Fi signals through the unshielded one of the wearable electronic device and the unshielded one of the wearable electronic device, so that interference of the user on receiving and transmitting Wi-Fi signals through the antennas when wearing or holding the wearable electronic device 100 is reduced.

Referring to fig. 2 or fig. 3, in some embodiments, the grounding end of the first antenna 120 is disposed on a side facing the second through slot 1161, and the radiation end of the first antenna 120 is disposed on a side opposite to the second antenna 130. The ground terminal of the second antenna 130 is disposed at a side facing the first through slot 1151, and the radiation terminal of the second antenna 130 is disposed at a side opposite to the first antenna 120. Thus, the radiation end of the first antenna 120 and the radiation end of the second antenna 130 are opposite to each other, which can increase the distance between the radiation ends of the two antennas, thereby reducing the mutual interference caused by the two antennas in the process of transmitting and receiving signals.

In some embodiments, the second antenna 130 can also be used for receiving and transmitting a Global Positioning System (GPS), that is, the second antenna 130 can receive and transmit a Wi-Fi signal and receive and transmit a GPS signal, so that the wearable electronic device 100 can receive and transmit different types of signals (e.g., receive and transmit a Wi-Fi signal, receive and transmit a GPS signal), and the communication range of the wearable electronic device 100 can be expanded.

Referring to fig. 2, in the present embodiment, the third antenna 140 may also be a slot antenna having the same structure as the first antenna 120 (or the second antenna 130). Specifically, the second bezel 112 and the middle bezel 114 are spaced apart from each other to form a third spaced gap 1172, the second bezel 112 is provided with a third through gap 1171 penetrating through the second bezel 112, and the third spaced gap 1172 is communicated with the third through gap 1171 to form the third antenna 140 on the second bezel 112. In this embodiment, there are two third through slots 1171, which are respectively located at two ends of the third antenna 140. In some embodiments, one of the third through slots 1171 (fig. 4) is located at one end of the third antenna 140.

Specifically, the third through slot 1171 causes the second bezel 112 to generally form fifth and sixth portions that are spaced apart from one another, the third spaced apart slot 1172 is located between the mid-bezel 114 and the fifth portion of the second bezel 112, and the third through slot 1171 communicates with the third spaced apart slot 1172 such that the fifth portion of the second bezel 112 forms the third antenna 140 that is generally independent of the mid-bezel 114. Wherein the length of the third spacing slot 1172 is substantially the same as the length of the third antenna 140. The third spacing slot 1172 is communicated with the third through slot 1171 to form the third antenna 140 on the second frame 112, and the third antenna 140 is directly exposed, so that interference of internal electronic devices on the third antenna 140 is avoided, and the strength of the third antenna 140 for receiving and transmitting Long Term Evolution (LTE) signals is further increased. In terms of process and cost, the antenna formed in this way can reduce the process of additionally arranging the separate third antenna 140 on the wearable electronic device 100, and reduce the production cost of the wearable electronic device 100.

The fifth and sixth sections are for convenience of description only and are not limiting; the slit width in the figure is only a schematic width and does not represent the actual slit width; the slit length in the figure is only a schematic length and does not represent the actual slit length.

In some embodiments, for example, the length of the third antenna 140 may be λ/4 or 3 λ/4 of an operating frequency band of the third antenna 140 when receiving and transmitting low-frequency radio frequency signals of long term evolution LTE, or may be other lengths, which only needs to satisfy the frequency band where the third antenna 140 receives and transmits signals.

In some embodiments, the first through slit 1151, the second through slit 1161, the third through slit 1172, the first through slit 1152, the second through slit 1161, and the third through slit 1171 may be provided with an insulating material therein, so as to enhance the strength of the connection structure between the first antenna 120 and the display portion 110 and the strength of the connection structure between the second antenna 130 and the display portion 110, thereby enhancing the overall strength of the first antenna 120, the second antenna 130, and the third antenna 140, and also increasing the overall strength of the display portion 110. The filled insulating material can be plastic or rubber, and the two can be fixed by injection molding and integral molding.

In some embodiments, the first bezel 111 and the second bezel 112 may be both non-metal bezels, for example, the first bezel 111 and the second bezel 112 may be made of plastic or rubber, and the first antenna 120, the second antenna 130, and the third antenna 140 may be formed on the non-metal bezels by using metal materials. The first antenna 120, the second antenna 130, and the third antenna 140 may be configured as non-slot antennas, for example, the first antenna 120 and the second antenna 130 may be directly disposed in the first frame 111, and the third antenna 140 may be disposed in the second frame 112, specifically, each of the first frame 111 and the second frame 112 may be provided with a mounting groove (not shown in the figure), the first antenna 120, the second antenna 130, and the third antenna 140 are respectively received in the corresponding mounting grooves, for example, the mounting grooves may be disposed on inner side surfaces or end surfaces of the first frame 111 and the second frame 112, where the inner side surfaces define a receiving space; the end surface refers to a surface along the thickness direction of the first frame 111. Conductive contacts (not shown) may be disposed in the mounting slots, and the first antenna 120, the second antenna 130, and the third antenna 140 may be coupled to feed points disposed on the circuit board through the corresponding conductive contacts, so that the first antenna 120, the second antenna 130, and the third antenna 140 are disposed in the first frame 111 and the second frame 112, respectively, and thus the antenna and the appearance of the antenna may be protected.

In some embodiments, one of the first frame 111 and the second frame 112 is a non-metal frame, and the other is a metal frame, for example, the first frame 111 is a metal frame, and the second frame 112 is a non-metal frame, wherein the first frame 111 and the second frame 130 can be formed by opening a slot, and the third antenna 140 can be directly embedded in the second frame 112.

In some embodiments, the first antenna 120, the second antenna 130, and the third antenna 140 may also be formed or connected to the first frame 111 and the second frame 112 by using a Laser Direct Structuring (LDS), a Direct printing technology (PDS), a Flexible printed circuit board (Flexible printed circuit), and the like, which are not described herein again.

Referring to fig. 2 again, in the present embodiment, the wearable electronic device 100 further includes a first band switching circuit 150, a second band switching circuit 160, and a third band switching circuit 170, the first band switching circuit 150 is connected to the first antenna 120, and the first band switching circuit 150 is configured to switch a band of the first antenna 120 for receiving and transmitting the Wi-Fi signal; the second frequency band switching circuit 160 is connected to the second antenna 130, and the second frequency band switching circuit 160 is configured to switch a frequency band of the Wi-Fi signal received by the second antenna 130; the third frequency band switching circuit 170 is connected to the third antenna 140, and the third frequency band switching circuit 170 is configured to switch a frequency band of the third antenna 140 for receiving and transmitting LTE signals.

Specifically, the first band switching circuit 150, the second band switching circuit 160 and the third band switching circuit 170 each include a switch and a matching circuit. For example, the first band switching circuit 150 (or the second band switching circuit 160) includes two matching circuits, and the switch is selectively connected to one of the matching circuits to switch the first antenna 120 (or the second antenna 130) to transmit and receive Wi-Fi signals of different bands. The third band switching circuit 170 includes three matching circuits, and the switch is selectively connected to one of the matching circuits to switch the third antenna 140 to transmit and receive LTE signals of different bands. The switch can be a single-pole three-throw switch, the matching circuit is capacitors with different capacitance values, the moving end of the switch is connected to the frequency band switching point of the antenna, and the stationary end of the switch is grounded.

Taking the third band switching circuit 170 as an example: the capacitance values of the three matching circuits are respectively set with the frequency bands corresponding to the third antenna 140, so that the switching of the LTE signal in three frequency bands of LB (700MHz-960MHz), MB (1710MHz-2170MHz) and HB (2300MHz-2690MHz) is realized through the third frequency band switching circuit 170.

The three matching circuits may be one of a capacitor, an inductor and an LC circuit (i.e., a circuit in which an inductor and a capacitor are arranged in parallel), respectively, and combined into a circuit connected to the switch. Accordingly, the value of the corresponding capacitor, inductor, or LC circuit is set according to the frequency band corresponding to the first antenna 120. Similarly, for the first antenna 120 and the second antenna 130 having multiple frequency bands, a frequency band switching circuit corresponding to the first antenna 120 and the second antenna 130 may be provided to control the first antenna 120 and the second antenna 130 to transmit and receive signals of different frequency bands, which is not described herein again.

In some embodiments, the wearable electronic device 100 may further include a number of first feeding points coupled to the first antenna 120, a number of second feeding points coupled to the second antenna 130, a third feeding point coupled to the third antenna 140, and so on, for feeding current signals so that the first antenna 120, the second antenna 130, and the third antenna 140 of the wearable electronic device 100 radiate corresponding signals.

Referring to fig. 5, in some embodiments, the wearable electronic device 100 may further include a fourth antenna 181, the fourth antenna 181 is disposed between the first frame 111 and the second frame 112, and the fourth antenna 181 may be configured to receive and transmit Wi-Fi signals and GPS signals.

Specifically, the fourth antenna 181 is disposed between the display surface 117 and the bottom shell 118, that is, the fourth antenna 181 is accommodated in the accommodating space, so that the fourth antenna 181 is embedded in the wearable electronic device 100 to form a hidden space.

Furthermore, in some embodiments, the fourth antenna 181 may also be disposed on the bottom case 118. The fourth Antenna 181 may be an IFA (inverted-F Antenna), a Loop Antenna, or a Slot Antenna.

Since the first antenna 120 and the second antenna 130 can both transmit and receive Wi-Fi signals, in the embodiment of the present application, the fourth antenna 181 is added to transmit and receive Wi-Fi signals, so that multiple transmission and multiple reception of Wi-Fi signals can be achieved through multiple antennas, and under the condition that frequency spectrum resources and antenna transmission power are not increased, system channel capacity can be increased exponentially, channel reliability can be increased, and communication quality can be improved. In addition, when any two of the first antenna 120, the second antenna 130 and the fourth antenna 181 are shielded and cannot transmit and receive Wi-Fi signals, the wearable electronic device 100 can transmit and receive Wi-Fi signals through the antennas which are not shielded, and accordingly interference of the transmission and reception of the Wi-Fi signals caused by holding of hands of a user can be reduced. In addition, by disposing the fourth antenna 181 between the first frame 111 and the second frame 112, it is possible to reduce interference between the fourth antenna 181 and other antennas (e.g., the first antenna 120, the second antenna 130, and the third antenna 140).

In some embodiments, as shown in fig. 5, the display portion 110 further includes an antenna bracket 119, the antenna bracket 119 is connected between the first frame 111 and the second frame 112, the fourth antenna 181 is disposed on the antenna bracket 119, and the fourth antenna 181 may be formed or connected to the bracket by a laser direct structuring technique, a direct printing technique, a flexible circuit board, or the like. For example, when the fourth antenna 181 is an inverted F antenna, the antenna holder 119 may be configured as an "F" type, and the fourth antenna 181 may be disposed on the antenna holder 119 through a process such as PDS or LDS. In addition, the fourth antenna 181 may also be disposed directly on the middle frame plate 114.

In some embodiments, referring to fig. 5, the ground terminal of the fourth antenna 181 is disposed on a side facing the radiation terminal of the second antenna 130, and the radiation terminal of the fourth antenna 181 is disposed on a side facing the ground terminal of the third antenna 140. Thus, the radiation end of the fourth antenna 181 is far away from the radiation end of the second antenna 130, and the radiation end of the fourth antenna 181 is far away from the radiation end of the third antenna 140, so that interference between the antennas (between the fourth antenna 181 and the second antenna 130, and between the fourth antenna 181 and the third antenna 140) caused by each other in the process of transmitting and receiving signals can be reduced.
