[0032] The following combination Figure 1 - Figure 12 An electronic device according to an embodiment of the present application is described.

[0033] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, an electronic device is provided, the electronic device including:

[0034] The device body 1, the protective cover 3 and the feeder 4, the device body 1 includes a first body 11 and a second body 12 that are relatively movable, and the protective cover 3 is arranged between the first body 11 and the second body 12. Figure 3 , the protective cover 3 includes.

[0035] See also Figure 3 The feeder line 4 is arranged on the inner side of the protective cover 3, and the feeder line 4 is used for signal radiation in the electronic device.

[0036] See also Figure 5 When the first body 11 and the second body 12 are folded, they are spaced apart from each other, exposing a gap 33. The feeder line 4 is disposed inside the protective cover 3, allowing the feeder line 4 and the gap 33 to form a slot antenna, allowing the radiated signal from the feeder line 4 to be emitted from the gap 33. This allows the feeder line 4 to improve the signal transmission performance of the antenna in the electronic device when the signal from other antennas on the electronic device is blocked by the user's hand.

[0037] See also Figure 1 When the first body 11 and the second body 12 are in the unfolded state, they are close to each other and can cover the gap 33 when they are relatively closed or intertwined. In this case, the signals of other antennas on the unfolded electronic device are not easily blocked. Therefore, the radiation of the feeder 4 can be turned off, and the other antennas on the electronic device can be used for signal transmission to reduce power consumption during antenna use.

[0038] In one embodiment, the protective cover 3 is rectangular. When the first body 11 and the second body 12 are folded, the slot 33 is centered along the length of the protective cover 3 and symmetrically located on the protective cover 3. The feeder line 4 can extend along the width of the protective cover 3. When the feeder line 4 and the slot 33 are perpendicular to each other, they couple to form a slot antenna, thereby ensuring the signal transmission performance of the antenna in the electronic device.

[0039] Specifically, when the feeder line 4 and the slot 33 cooperate, the coupled feeder line formed by the feeder line 4 is a clear section of the line, that is, the feeder line 4 has no reference ground. The feeder line 4 couples and excites the slot 33 in the protective cover 3, so that when the electronic device is folded, the feeder line 4 and the slot 33 form a coupled-feed slot antenna. In this case, the feeder line 4 is not easily obstructed even when the electronic device is held in the hand, thereby improving the antenna performance of the electronic device in the folded state.

[0040] The electronic device provided in some embodiments of the present application includes a device body 1, a protective cover 3 and a feeder 4, wherein the device body 1 includes a first body 11 and a second body 12 that are relatively movable, the protective cover 3 is arranged between the first body 11 and the second body 12, and the feeder 4 is arranged on the inner side of the protective cover 3. When the first body 11 and the second body 12 are in a folded state, the feeder 4 and the slot 33 can form a slot antenna, so that the radiation signal of the feeder 4 is emitted from the slot 33, and the feeder 4 can be used to improve the signal transmission performance of the antenna in the electronic device. When the first body 11 and the second body 12 are in an unfolded state, the first body 11 and the second body 12 can cover the slot 33 to reduce power consumption during the use of the antenna.

[0041] Alternatively, see Figure 2 The width H of the gap 33 is in the range of 0.5 mm to 2.0 mm.

[0042] Specifically, the slot 33 can be a long strip-shaped slot. When the width H of the slot 33 is in the range of 0.5mm-2.0mm, it can be ensured that the width H of the slot 33 is much smaller than the wavelength of the signal radiated by the feeder 4, so as to ensure the radiation efficiency of the slot antenna formed by the feeder 4 and the slot 33.

[0043] Alternatively, see Figure 10 The protective cover 3 is rectangular, and the gap 33 includes a first gap 331 , which extends along the length direction of the protective cover 3 .

[0044] Specifically, when the first slot 331 extends along the length direction of the protective cover 3, the first slot 331 can be formed into a long strip-shaped slot to ensure that the first slot 331 has a higher aspect ratio, thereby improving the coupling efficiency between the feed line 4 and the slot 33, and ensuring the radiation effect of the slot antenna formed by the feed line 4 and the slot 33.

[0045] Alternatively, see Figure 10 and Figure 11 The gap 33 includes a second gap 332 , which is perpendicular to the first gap 331 and communicates with the first gap 331 .

[0046] Specifically, the second slot 332 cooperates with the first slot 331 to improve the low-frequency signal radiation efficiency of the slot antenna formed by the feed line 4 and the slot 33. However, low-frequency signals in electronic devices are generally weak, or low-frequency antennas in electronic devices are easily blocked by users when holding them. The slot antenna formed by the feed line 4 and the slot 33 can specifically improve the low-frequency signal radiation efficiency of electronic devices, ensuring signal coverage of electronic devices across multiple frequency bands.

[0047] In one embodiment, see Figure 10 The slot 33 includes two second slots 332, one located at each end of the first slot 331. The second slots 332 and the first slot 331 form an I-shaped slot 33, which can shift the slot antenna's radiation frequency toward a lower frequency, ensuring comprehensive signal radiation from the electronic device.

[0048] In another embodiment, see Figure 11 The slot 33 includes three second slots 332 or more second slots 332, and the multiple second slots 332 are perpendicular to the first slot 331 and connected to the first slot 331, which can also achieve the purpose of adjusting the radiation frequency of the slot antenna to a low frequency.

[0049] Alternatively, see Figure 12 The gap 33 includes a plurality of first gaps 331 , and the plurality of first gaps 331 are arranged side by side and spaced apart.

[0050] Specifically, when multiple first slots 331 are arranged side by side and spaced apart from each other, the lengths of the multiple first slots 331 can be the same, or the lengths of the multiple first slots 331 can be different, or the lengths of some of the multiple first slots 331 can be the same. Arranging multiple first slots 331 side by side can form a slot antenna with multi-frequency radiation. For example, two first slots 331 are arranged side by side to form a dual-frequency slot antenna with the feeder 4 and the slot 33, or three first slots 331 are arranged side by side to form a triple-frequency slot antenna with the feeder 4 and the slot 33, thereby increasing the diversity of the slot antenna's radiation frequencies.

[0051] In addition, the plurality of first slots 331 may be cross-matched with the plurality of second slots 332 to form a grid-shaped slot antenna.

[0052] Alternatively, see Figure 1 The electronic device further includes a first circuit board 7 and a second circuit board 8, wherein the first circuit board 7 is disposed in the first body 11, the second circuit board 8 is disposed in the second body 12, and the first circuit board 7 and the second circuit board 8 are connected via a flexible circuit board 9;

[0053] A first transmission line 91 is provided on the flexible circuit board 9 , and the feeder 4 is connected to the first circuit board 7 via the first transmission line 91 .

[0054] Specifically, a wireless transceiver chip circuit may be provided on the first circuit board 7. The wireless transceiver chip circuit may include radio frequency front-end components such as a transceiver, a PA (power amplifier), an LNA (low noise amplifier), a switch (antenna switching switch), a duplexer (duplexer), and a filter (filter). Furthermore, an RFBTB (radio frequency connector) may be provided on the first circuit board 7. The RF BTB is mounted on the first circuit board 7 via an SMT (surface mount technology) patch and may be connected to the transceiver via traces on the first circuit board 7.

[0055] The flexible printed circuit board 9 is provided with transmission lines connected to the first printed circuit board 7. The transmission lines can be RF transmission lines, signal lines, control lines, or power lines, and can be microstrip lines or strip lines. Some transmission lines can connect the first printed circuit board 7 and the second printed circuit board 8 to ensure signal transmission between the first and second printed circuit boards 7 and 8; some transmission lines can connect the first printed circuit board 7 with other antennas. For example, the first transmission line 91 can connect the feeder line 4 to the first printed circuit board 7, enabling the first printed circuit board 7 to flexibly control the feeder line 4.

[0056] Alternatively, see Figure 1 and Figure 2The electronic device further includes a second transmission line 5 and a third transmission line 6, the second transmission line 5 is provided on the flexible circuit board 9 and connects the first circuit board 7 and the second circuit board 8, the third transmission line 6 is provided on the flexible circuit board 9 and connects the first circuit board 7 and the second circuit board 8;

[0057] The second transmission line 5 is used to transmit low-frequency signals, and the third transmission line 6 is used to transmit medium- and high-frequency signals.

[0058] Specifically, the first transmission line 91 , the second transmission line 5 and the third transmission line 6 may all be RF transmission lines, that is, the first transmission line 91 , the second transmission line 5 and the third transmission line 6 are transmission lines with a transmission frequency of 0.5 GHz to 3 GHz.

[0059] One end of the first transmission line 91 is connected to the RF BTB on the first circuit board 7, and the other end of the first transmission line 91 is connected to the feeder 4 spanning the above-mentioned gap 33. The electronic device uses a section of the feeder 4 on the flexible circuit board 9 and the gap 33 for coupling excitation, which can improve the signal radiation effect of the electronic device without increasing additional costs.

[0060] One end of the second and third transmission lines 5, 6 can be connected to the RFBTB on the first circuit board 7, and the other ends can be snapped into the BTB on the second circuit board 8. Furthermore, the second and third transmission lines 5, 6 can transmit low-frequency signals and medium- and high-frequency signals, respectively, to ensure comprehensive signal radiation from the electronic device. Furthermore, the second and third transmission lines 5, 6 can also feed the low-frequency antenna and medium- and high-frequency antenna, respectively, through the BTB and traces on the second circuit board 8.

[0061] Alternatively, see Figure 4 , the electronic device further includes a switch 92, the switch 92 being disposed between the first transmission line 91 and the second transmission line 5, and being used to switch the connection between the first circuit board 7 and the first transmission line 91 or to switch the connection between the first circuit board 7 and the second transmission line 5;

[0062] When the first body 11 and the second body 12 are in the folded state, the switch 92 switches to the first transmission line 91 and connects the first circuit board 7 to the first transmission line 91, and the slot antenna is used to transmit low-frequency signals;

[0063] When the first body 11 and the second body 12 are in the unfolded state, the switch 92 switches to the second transmission line 5 and connects the first circuit board 7 to the second transmission line 5 , where the second transmission line 5 is used to transmit low-frequency signals.

[0064] Specifically, the switching switch 92 can be set on the wireless transceiver chip circuit of the first circuit board 7 and serve as a switch to switch the connection between the first circuit board 7 and the first transmission line 91 or the second transmission line 5 .

[0065] When the first body 11 and the second body 12 are in the folded state, the switch 92 connects the first circuit board 7 to the first transmission line 91, and the slot antenna is used to transmit low-frequency signals. Figure 5 , at this time, the signal radiation direction of the slot antenna is away from the electronic device, that is, Figure 5 When an electronic device is folded, the performance of the frame antenna on the electronic device will be reduced, especially the low-frequency radiation performance of the frame antenna will be reduced by about 3-5dB. If the user holds the electronic device and blocks the frame antenna, the performance of the frame antenna will be further deteriorated.

[0066] The slot antenna provided in the embodiment of the present application can still maintain high radiation performance when the electronic device is in a folded state, and the slot antenna is less likely to be held by a user when the electronic device is in a folded state, thereby greatly improving the antenna performance of the electronic device, further solving the problem that the position where the antenna can be set on the electronic device in the folded state is very limited, and ensuring the signal radiation efficiency of the electronic device in different states.

[0067] Alternatively, see Figure 3 The electronic device further includes a plastic layer 10 , and the plastic layer 10 fills the gap 33 .

[0068] Specifically, the plastic layer 10 is a dielectric material with low dielectric constant and low loss. When the plastic layer 10 closes the gap 33, on the one hand, it can ensure that the radiation signal of the feeder 4 is emitted from the gap 33, thereby improving the radiation performance of the feeder 4. On the other hand, it can protect the feeder 4 and prevent the feeder 4 from being damaged when it is directly exposed.

[0069] Optionally, the electronic device further includes a Hall sensor, which is connected to the first circuit board 7 and is used to determine the relative state of the first body 11 and the second body 12 .

[0070] Specifically, when the relative position of the first body 11 and the second body 12 changes, the operating state of the feeder 4 also changes accordingly. For example, when the first body 11 and the second body 12 are in a folded state, the feeder 4 is exposed from the gap 33, so that the radiation signal of the feeder 4 during operation is emitted from the gap 33. When the first body 11 and the second body 12 are in an unfolded state, the first body 11 and the second body 12 can cover the gap 33, and the feeder 4 can be closed.

[0071] After determining the relative state of the first body 11 and the second body 12, the Hall sensor can transmit the relative state information of the first body 11 and the second body 12 to the first circuit board 7, so that the first circuit board 7 can control the operation or shutdown of the feeder 4 according to the relative state of the first body 11 and the second body 12.

[0072] Also, see Figure 1 The electronic device further includes a flexible screen 2 and a camera module 100 . The flexible screen 2 is disposed on the device body 1 , and the feeder 4 is disposed between the protective cover 3 and the flexible screen 2 . The camera module 100 is disposed on the first body 11 .

[0073] In one embodiment, see Figure 3 A hinge 200 is provided between the first body 11 and the second body 12. During the relative folding and unfolding of the first body 11 and the second body 12, the hinge 200 can cooperate with the flexible screen 2 to fold and unfold to ensure the structural integrity of the flexible screen 2 during the folding and unfolding process.

[0074] In addition, the protective cover 3 is a hinge cover provided directly above the hinge 200 . The protective cover 3 is a metal cover and is fixed to the first body 11 and the second body 12 by screws.

[0075] In one embodiment, see Figure 1 The relative folding between the first body 11 and the second body 12 can be up and down folding to achieve the lightness and thinness of the electronic device, so that the volume of the electronic device after folding is smaller and the appearance is more beautiful.

[0076] In another embodiment, see Figures 6 to 9 The relative folding between the first body 11 and the second body 12 can be left and right folding to increase the display area of ​​the flexible screen 2 and increase the control function of the electronic device.
