The first rotating member 30 is located in the central region of the electronic apparatus 100, which means that the center line of the first rotating member 30 is substantially coincident with the center line of the electronic apparatus 100 (a small amount of deviation is allowed).

When the first housing 10 and the second housing 20 are in the closed state, the positions of the fifth antenna 32 and the first antenna 21 are completely staggered, so that resonance interference between the fifth antenna 32 and the first antenna 21 can be avoided when the first housing 10 and the second housing 20 are in the closed state, and when the fifth antenna 32 and the first antenna 21 work simultaneously, so as to influence the signal transmission performance of the first antenna 21 and the fifth antenna 32.

In this embodiment, when the first casing 10 and the second casing 20 are in the closed state, the position of the fifth antenna 32 may partially overlap the position of the second antenna 22. In other embodiments, the position of the fifth antenna 32 may also completely overlap the position of the second antenna 22. In this embodiment, when the first housing 10 and the second housing 20 are in the closed state, the position of the fifth antenna 32 overlaps with the position of the second antenna 22, and the fifth antenna 32 and the second antenna 22 operate simultaneously, because there is no overlapping portion between the operating frequencies of the fifth antenna 32 and the second antenna 22, no resonance interference is generated between the fifth antenna 32 and the second antenna 22, thereby avoiding the influence on the communication performance of the electronic device 100.

In one embodiment, the position of the fifth antenna may also partially overlap with the position of the third antenna. In other embodiments, the position of the fifth antenna may also completely overlap with the position of the third antenna. Because the operating frequencies of the fifth antenna and the third antenna do not have an overlapping portion, no resonance interference is generated between the fifth antenna and the third antenna, and thus, the influence on the communication performance of the electronic device 100 can be avoided.

Referring to fig. 3, in an embodiment, the first antenna 21 is a medium-high frequency antenna, the second antenna 22 is a medium-frequency antenna, the third antenna 23 is a first low-frequency antenna, and the medium-high frequency antenna, the medium-frequency antenna and the first low-frequency antenna are sequentially arranged along an edge of the first housing 10. The fourth antenna 31 is a second low-frequency antenna, the fifth antenna 32 is a high-frequency antenna, and the second low-frequency antenna and the high-frequency antenna are disposed along the edge of the second housing 20. When the first housing 10 and the second housing 20 are in the closed state, the position of the high frequency antenna and the position of the intermediate frequency antenna partially overlap, and in other embodiments, the position of the high frequency antenna and the position of the intermediate frequency antenna may completely overlap. The position of high frequency antenna with well high frequency antenna staggers the setting, first low frequency antenna with the setting of staggering of second low frequency antenna.

In this embodiment, the first low-frequency antenna and the second low-frequency antenna which have the same frequency bands, and the high-frequency antenna and the middle-high-frequency antenna which have the overlapping portions are staggered, so that the resonance interference generated between the first low-frequency antenna and the second low-frequency antenna when the electronic device 100 is folded to the closed state can be avoided, and the resonance interference generated between the high-frequency antenna and the middle-high-frequency antenna can be avoided. Meanwhile, the high-frequency antenna and the intermediate-frequency antenna with different frequency bands are arranged at the overlapping positions, so that resonance interference between the mutually overlapped antennas can be avoided, the communication performance of the electronic device 100 is ensured, and meanwhile, a space-saving effect can be achieved.

In one embodiment, when the first housing 10 and the second housing 20 are in the closed state, the position of the high frequency antenna overlaps with the first low frequency antenna. In other embodiments, the high frequency antenna may be positioned to completely overlap the first low frequency antenna. The working frequency bands of the high-frequency antenna and the first low-frequency antenna are different, and when the electronic device 100 is folded to a closed state, the high-frequency antenna and the first low-frequency antenna which are overlapped in position do not interfere with each other, and the communication performance of the electronic device 100 is not affected.

With continued reference to fig. 3, the first antenna set may further include a sixth antenna 24, a seventh antenna 25, and an eighth antenna 26. The sixth antenna 24 is a second medium-high frequency antenna, the seventh antenna 25 is a third medium-high frequency antenna, and the eighth antenna 26 is a fourth medium-high frequency antenna. The sixth antenna 24, the seventh antenna 25 and the eighth antenna 26 are disposed at the edge of the first housing 10. Specifically, the sixth antenna 24 is located at the second position 2, the seventh antenna 25 is located at the fourth position 4, and the eighth antenna 26 is located at the fifth position 5. When the electronic device 100 is folded to the closed state, the second middle and high frequency antenna and the second low frequency antenna are partially overlapped, and because the working frequency bands of the second middle and high frequency antenna and the second low frequency antenna are different, even when the electronic device 100 is folded to the closed state, the second middle and high frequency antenna and the second low frequency antenna which are mutually overlapped do not generate resonance interference.

The third middle and high frequency antenna and the fourth middle and high frequency antenna overlap the blank area of the second housing 20. When the first casing 10 and the second casing 20 are folded to the closed state, the third middle and high frequency antenna and the fourth middle and high frequency antenna may also operate normally, thereby improving the communication performance of the electronic device 100.

The third casing 40 is made of the same material as the first casing 10 and the second casing 20, and may be a metal plate, a plastic plate, or a combination of metal and plastic injection molding. The third housing 40 may house or carry components of the electronic device 100, such as a display screen, a circuit board, and a battery. The size of the third housing 40 may be the same as the size of the second housing 20, or may be smaller than the size of the second housing 20.

The electronic device 100 further includes a second rotating member 31, and the second rotating member 31 rotatably connects the second housing 20 and the third housing 40, so that the third housing 40 and the second housing 20 rotate relatively. When the third housing 40 is turned around the second rotating member 31 toward the direction approaching the second housing 20 until the third housing 40 overlaps the second housing 20, the third housing 40 is in a closed state with respect to the second housing 20. When the third housing 40 is turned around the second rotating member 31 in a direction away from the second housing 20 until the third housing 40 is unfolded relative to the second housing 20 and is in the same plane, the third housing 40 is in an open state relative to the second housing 20.

In this embodiment, when the first casing 10 and the third casing 40 are both in the closed state relative to the second casing 20, the electronic device 100 can be folded to a smaller volume, thereby increasing the portability of the electronic device 100. When the first casing 10 and the third casing 40 are both in an open state relative to the second casing 20, the display screens of the first casing 10, the second casing 20, and the third casing 40 can be unfolded to display screens with a larger area, so that the display area of the electronic device 100 is increased, and the use experience of a user is improved.

Referring to fig. 4, a third antenna set is disposed on the third housing 40, and the third antenna set includes one antenna, and in other embodiments, the third antenna set may include a plurality of antennas. When the third casing 40 is folded to a closed state relative to the second casing 20, the positions of the antennas in the third antenna group and the positions of the antennas in the second antenna group are partially overlapped, and the operating frequency bands of the antennas in the second antenna group and the antennas in the third antenna group, which are partially overlapped with each other, are different and have no overlapped part. When the third casing 40 is unfolded to an open state relative to the second casing 20, the working frequency bands of the antennas in the second antenna group and the antennas in the third antenna group, which are partially overlapped with each other in the closed state, are different.

In this embodiment, by setting the antennas in the third antenna group and the second antenna group at mutually overlapping positions in a staggered manner, when the third casing 40 is in a closed state relative to the second casing 20, no signal interference is generated between the mutually overlapping antennas in the third antenna group and the second antenna group, and no influence is generated on the communication and data interaction functions of the electronic device 100, so that the use experience of a user is improved.

In an embodiment, when the third casing 40 is folded to the closed state relative to the second casing 20, the positions of the antennas in the third antenna group and the positions of the antennas in the second antenna group may also be completely overlapped, and the operating frequency bands of the antennas in the second antenna group and the antennas in the third antenna group that are overlapped are different and have no overlapping portion. When the third casing 40 is unfolded to an open state relative to the second casing 20, the working frequency bands of the antennas in the second antenna group and the antennas in the third antenna group which are overlapped with each other in the closed state are different. By completely overlapping the antennas in the third antenna group and the second antenna group and performing frequency-staggered setting on the overlapped antennas, the space can be further saved while avoiding resonance interference between the antennas with overlapped positions, so that the electronic device 100 can set more antennas in a limited space, thereby improving the communication performance of the electronic device 100.
