when the first housing 1 and the second housing 2 are in the folded state, the first electrical contact 6 is in contact conduction with the fourth electrical contact 12, and the second electrical contact 7 is in contact conduction with the third electrical contact 11.
The Mobile terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
The first housing 1 and the second housing 2 may be connected by a rotating shaft or a sliding rail. When the first casing 1 and the second casing 2 are connected by a rotating shaft, the first casing 1 and the second casing 2 may be relatively moved to a folded state or an unfolded state by rotating around the rotating shaft. When the first casing 1 and the second casing 2 are connected by a slide rail, the first casing 1 and the second casing 2 may be relatively moved to a folded state or an unfolded state by sliding along the slide rail. The first housing 1 and the second housing 2 may also be folded and unfolded by other connection methods, which is not limited in the embodiments of the present invention.
The side of the first casing 1 may be a frame of the first casing 1; referring to fig. 1 and 2, the first radiating arm 3 may be electrically isolated from the first housing 1 by using a break 13, and further, the break 13 between the first radiating arm 3 and the first housing 1 may be filled with a non-conductive material (e.g., plastic) in consideration of the aesthetic appearance of the mobile terminal. The material of the first electrical contact 6 may be metal or conductive nonmetal; the material of the second electrical contact 7 may be metal or conductive nonmetal.
The side of the second casing 2 may be a frame of the second casing 2; referring to fig. 1 and 2, the second radiating arm 4 may be electrically isolated from the second housing 2 by using a break 14, and further, the break 14 between the second radiating arm 4 and the second housing 2 may be filled with a non-conductive material (e.g., plastic) in consideration of the aesthetic appearance of the mobile terminal. The third electrical contact 11 may be made of metal or conductive nonmetal; the material of the fourth electrical contact 12 may be metal or conductive nonmetal.
The first and second radiating arms 3 and 4, the first and second radiating arms 3 and 2, and the first and second housings 1 and 4 may be electrically isolated from each other. The first signal source 9 may be an NFC signal source.
In the embodiment of the invention, when the mobile terminal is in the folded state, the working path of the antenna (as shown in fig. 3, the working path of the antenna in the folded state is that the first signal source → the second electric contact → the third electric contact → the second radiation arm → the second grounding point → the fourth electric contact → the first radiation arm → the first grounding point → the first signal source) sequentially passes through the two shells to form a closed loop with two loops of current, so that the magnetic flux of the antenna can be greatly improved, and the performance of the antenna in the folded state of the mobile terminal can be improved. Therefore, when the mobile terminal is applied to the NFC antenna (namely, when the first signal source adopts the NFC signal source), the magnetic flux of the NFC antenna can be greatly improved when the mobile terminal is in a folded state, and therefore the mobile terminal can be well applicable to a use scene with high requirements on the performance of the NFC antenna only by folding the mobile terminal.
Optionally, the mobile terminal further comprises a switch 8, and the first electrical contact 6 is electrically connected with the second electrical contact 7 through the switch 8;
when the first shell 1 and the second shell 2 are in the unfolding state, the switch 8 is in the conducting state; when the first casing 1 and the second casing 2 are in the folded state, the switch 8 is in the off state.
Wherein the switch 8 may be used to make or break the electrical connection between the first electrical contact 6 and the second electrical contact 7, for example, when the switch 8 is in a conducting state, the first electrical contact 6 and the second electrical contact 7 are electrically conducted; when the switch 8 is in the off state, the first electrical contact 6 and the second electrical contact 7 are electrically disconnected.
When the mobile terminal is in a folded state, the working path of the antenna sequentially passes through the two shells by the disconnecting switch to form a closed loop with two circles of current loops, and when the mobile terminal is in an unfolded state, the working path of the antenna (the working path of the antenna in the unfolded state is: a first signal source → a second electric contact → a switch → a first electric contact → a first radiation arm → a first grounding point → a first signal source) can also pass through the first shell to form a closed loop with one circle of current loops by the conducting switch, so that the antenna of the mobile terminal can work when the mobile terminal is in the closed state or the unfolded state.
Alternatively, the first electrical contact 6 is electrically connected to the end of the first radiating arm 3, the end of the second end of the first radiating arm 3 is grounded, the third electrical contact 11 is electrically connected to the end of the first end of the second radiating arm 4, and the end of the second radiating arm 4 is grounded.
Thus, the number of turns (turns) of a current loop formed by the antenna can be increased, so that the magnetic flux of the antenna can be further improved, and the performance of the antenna can be further improved.
Optionally, the first radiating arm 3 has a first connection point 31 and a first grounding point 32, the first connection point 31 is electrically connected with the first electrical contact 6, and the first grounding point 32 is grounded; the second radiating arm 4 has a second connection point 41 and a second grounding point 42, the second connection point 41 being electrically connected to the third electrical contact 11, the second grounding point 42 being grounded;
when the first housing 1 and the second housing 2 are folded, the first connection point 31 and the second connection point 41 are aligned with each other, and the first grounding point 32 and the second grounding point 42 are aligned with each other.
Alternatively, when the first casing 1 and the second casing 2 are in the folded state, the first radiation arm 3 and the second radiation arm 4 are aligned with each other.
The first radiation arm 3 and the second radiation arm 4 are aligned with each other, which may mean that the first radiation arm 3 and the second radiation arm 4 have the same shape and size, and are aligned with each other when the first housing 1 and the second housing 2 are in the folded state.
In this way, the first radiation arm and the second radiation arm are aligned with each other when the first casing and the second casing are in the folded state, so that the appearance of the mobile terminal can be more neat and beautiful.
Alternatively, when the first and second housings 1 and 2 are in the folded state, the first and fourth electrical contacts 6 and 12 are aligned with each other, and the second and third electrical contacts 7 and 11 are aligned with each other.
Therefore, when the first shell and the second shell are in the folded state, the first electric contact and the fourth electric contact as well as the second electric contact and the third electric contact are aligned with each other, so that the contact conduction effect between the first electric contact and the fourth electric contact as well as between the second electric contact and the third electric contact is better.
Optionally, the first radiating arm 3 is electrically connected to a second signal source 15, and the second signal source 15 is a different signal source from the first signal source 9.
The second signal source 15 may be a radio frequency module such as a second Generation mobile phone communication technology specification (2-Generation WIreless telephone technology, 2G), a third Generation mobile communication technology (3rd-Generation, 3G), a fourth Generation mobile communication technology (4 th Generation mobile communication technology, 4G), a fifth Generation mobile communication technology (5th-Generation, 5G), WIreless Fidelity (WIFI), or a Global Positioning System (GPS).
In this way, since the first radiating arm is also electrically connected with the second signal source, the radiating arm can simultaneously realize multiple antenna functions, for example, the NFC antenna function and the 4G antenna function can be simultaneously realized, and thus, the assembly space and the manufacturing cost of the mobile terminal can be saved.
Optionally, the second electrical contact 7 is electrically connected to the first signal source 9 through the first inductor 5; and/or the presence of a gas in the gas,
the fourth electrical contact 12 is connected to ground via the second inductor 10.
The first inductor 5 may be configured to isolate an electromagnetic wave having a frequency greater than a preset threshold, that is, to present a high impedance when the frequency is greater than the preset threshold and to present a low impedance when the frequency is less than or equal to the preset threshold; the preset threshold may be set according to specific requirements, and the embodiment of the present invention is not limited thereto, for example, when the preset threshold is applied to an NFC antenna, the preset threshold may be 13.56 MHZ.
The second inductor 10 may be for isolating electromagnetic waves having a frequency greater than a preset threshold, i.e., exhibiting a high impedance when the frequency is greater than the preset threshold and exhibiting a low impedance when the frequency is less than or equal to the preset threshold; the preset threshold may be set according to specific requirements, and the embodiment of the present invention is not limited thereto, for example, when the preset threshold is applied to an NFC antenna, the preset threshold may be 13.56 MHZ.
In this way, providing the first inductor between the second electrical contact and the first signal source and/or providing the second inductor between the fourth electrical contact and the second ground point can reduce mutual interference between antennas of different resonance frequencies. For example, when the first signal source is an NFC signal source and the second signal source is a non-NFC signal source, since the resonant frequency of the NFC antenna is low and the resonant frequency of the non-NFC antenna is generally high, the mutual interference between the NFC antenna and the non-NFC antenna can be reduced by providing the first inductor and/or the second inductor.
As shown in fig. 4, an embodiment of the present invention provides an antenna control method applied to a mobile terminal in the foregoing embodiment, including:
when the first shell and the second shell are in the folded state, the switch is controlled to be in an off state.
When the mobile terminal is in a folded state, the working path of the antenna sequentially passes through the two shells to form a closed loop with two loops of current by disconnecting the switch, so that the magnetic flux of the antenna can be greatly improved, and the performance of the antenna can be improved when the mobile terminal is in the folded state.
