In addition, as shown in fig. 4, two sides of the retractable electronic device 40 are respectively provided with a radio frequency module 44 and an antenna 45, the radio frequency module 44 and the antenna 45 can be connected by a radio frequency trace arranged between two adjacent movable plates, and the purpose of adjusting the length of the radio frequency signal line between the radio frequency module 44 and the antenna 45 along with the retractable state of the retractable electronic device 40 can be achieved by switching to different radio frequency traces.
Specifically, in an embodiment, a plurality of radio frequency traces may be disposed between two adjacent movable plates, each radio frequency trace corresponds to a telescopic state, and a length of each radio frequency trace may be determined according to a distance between the radio frequency module 44 and the antenna 45 in the corresponding telescopic state, when the telescopic electronic device 40 is in different telescopic states, the radio frequency module 44 and the antenna 45 may be connected by different radio frequency traces, so that an effect that a length of a radio frequency signal line between the radio frequency module 44 and the antenna 45 is adjustable along with the telescopic state is achieved.

That is to say, in the process of switching the telescopic electronic device 40 to the target telescopic state, two adjacent movable plates slide between each other, so that the radio frequency module 44 and the antenna 45 are connected to the target radio frequency trace corresponding to the target telescopic state, the target telescopic state is one of a plurality of telescopic states possessed by the telescopic electronic device 40, and for different telescopic states of the plurality of telescopic states, the lengths of the radio frequency traces conducted between the radio frequency module 44 and the antenna 45 are different, and specifically, the radio frequency trace conduction distance can be adaptively changed along with the distance between the radio frequency module 44 and the antenna 45 in different telescopic states by switching to different radio frequency traces.
Optionally, M radio frequency traces with different lengths are arranged between two adjacent movable plates, two ends of each radio frequency trace are respectively connected to the radio frequency module 44 and the antenna 45, and M is an integer greater than 1;

and when the contact on the first section of wiring is contacted with the contact on the second section of wiring, the radio frequency wiring is conducted.
That is, each rf trace includes two portions, namely a first trace located on the first movable board and a second trace located on the second movable board, where the first movable board and the second movable board are two adjacent movable boards, and contacts are disposed at appropriate positions on the first trace and the second trace, when the telescopic electronic device 40 is in an appropriate telescopic state, the contact on the first trace of the corresponding rf trace contacts with the contact on the second trace of the corresponding rf trace, so that the rf trace is conducted, and the rf module 44 and the antenna 45 are connected through the rf trace. It should be noted that each rf trace is only conducted in a corresponding one of the stretching states, but not conducted in other stretching states, and only one rf trace is conducted in each stretching state.
Therefore, the radio frequency wires can be conducted in a corresponding telescopic state by arranging the contacts at the proper positions of the two wires of each radio frequency wire.
Optionally, N sets of movable plates are staggered between the first housing 41 and the second housing 42, each set of movable plates includes two adjacent movable plates respectively disposed on the first housing 41 and the second housing 42, a radio frequency cable is disposed between each set of movable plates, and N is an integer greater than 1;
when the retractable electronic device 40 is in the target retractable state, the radio frequency traces between the target group of active plates are conducted, the target group of active plates is a group of active plates corresponding to the target retractable state, and the conducting lengths of the radio frequency traces between different groups of active plates are different.
That is, in another embodiment, a plurality of sets of movable plates disposed between the first casing 41 and the second casing 42 in a staggered manner may be utilized, and specifically, N movable plates are disposed on both the first casing 41 and the second casing 42, and the N movable plates on the first casing 41 side are disposed in a staggered manner with the N movable plates on the second casing 42 side, and each set of movable plates includes two adjacent movable plates disposed on the first casing 41 and the second casing 42, respectively; and radio frequency wires are respectively arranged between each group of movable plates, and the lengths of the radio frequency wires between different groups of movable plates can be different and respectively correspond to different telescopic states. When the telescopic electronic device 40 is in the target telescopic state, the radio frequency traces between the target group movable plates corresponding to the target telescopic state are conducted.
In this way, by arranging one radio frequency cable between every two adjacent movable plates and ensuring that the radio frequency cables between each group of movable plates respectively correspond to a telescopic state, the radio frequency cables between different groups of movable plates can be switched along with the telescopic state, and the purpose of adjusting the length of the radio frequency cables between the radio frequency module 44 and the antenna 45 can be achieved.
Optionally, the radio frequency traces between each group of movable plates include a first segment trace located on the first movable plate and a second segment trace located on the second movable plate, contacts are arranged on the first segment trace and the second segment trace, the first movable plate and the second movable plate are a group of movable plates, and the positions of the contacts on the radio frequency traces between different groups of movable plates are different.

When the retractable electronic device 40 is in a proper retractable state, the contact on the first section of the rf trace between the corresponding set of active plates contacts the contact on the second section of the rf trace, so that the rf trace is conducted, and the rf module 44 and the antenna 45 are connected through the rf trace. It should be noted that the radio frequency traces between each group of movable plates are only conducted in a corresponding one of the telescopic states, but are not conducted in other telescopic states, and in each telescopic state, only the radio frequency traces between one group of movable plates are conducted.
As shown in fig. 5 (wherein fig. 5 only illustrates two sets of panels), the first panel 431 of each set of panels is provided with a first section of trace 461, a first end of the first section of trace 461, that is, an end close to the first housing 41, is connected to the rf module 44, the second panel 432 of each set of panels is provided with a second section of trace 462, and a first end of the second section of trace 462, that is, an end close to the second housing 42, is connected to the antenna 45. That is to say, the rf module 44 can be correspondingly connected to the first traces 461 on the N first movable boards 431 of the N sets of movable boards through the N circuit channels, respectively, and the antenna 45 can also be correspondingly connected to the second traces 462 on the N second movable boards 432 of the N sets of movable boards through the N circuit channels, respectively. The first trace 461 and the second trace 462 are both provided with contacts, and the positions of the contacts on the rf traces between different sets of the movable plates are different, so that the rf module 44 can be in rf connection with the antenna 45 by contacting the contacts on the rf traces between different sets of the movable plates when the retractable electronic device 40 is in different retractable states. The contact may be a spring or other conductive metal sheet.
Suppose that as shown in fig. 5, the first segment of the trace 461 on the first movable board 431 of the two sets of movable boards is provided with 1 contact at different positions, namely the a1 contact and the a2 contact, and the second segment of the trace 462 on the second movable board 432 of the two sets of movable boards is provided with 1 contact at the same position, namely the b1 contact and the b2 contact. Thus, when the retractable electronic device 40 is in the first retracted state, such as the extended state, the second end of the first movable plate 431 is close to the second end of the second movable plate 432, so that the contact a1 on the first trace 461 on the first movable plate 431 of one set of movable plates can be in contact with the contact b1 on the second trace 462 on the second movable plate 432 of the set of movable plates, and at this time, the length of the rf signal line between the rf module 44 and the antenna 45 is longer; when the retractable electronic device 40 is in the second retractable state, such as the retracted state, the second end of the first movable plate 431 is close to the first end of the second movable plate 432, so that the contact a2 on the first trace 461 on the first movable plate 431 of the other set of movable plates can be in contact with the contact b2 on the second trace 462 on the second movable plate 432 of the set of movable plates, and at this time, the length of the rf signal line between the rf module 44 and the antenna 45 is short, thereby reducing the attenuation of the rf signal during transmission. Of course, the second segment of the trace 462 on the second active board 432 of the two active boards can also be provided with contacts at different positions, as long as it is ensured that one active board can be contacted by the contacts on the respective rf trace in different telescopic states.
It should be noted that, the side of the telescopic electronic device 40 where the radio frequency module 44 is disposed may also be provided with an antenna, but the connection manner between the antenna on the side and the radio frequency module is only, and since there is no change in distance, the arrangement may be performed by referring to the conventional manner of fixing the length of the radio frequency signal line.
Therefore, the radio frequency wiring between the movable plates of the group can be conducted in a corresponding telescopic state by arranging the contacts at the proper positions of the two sections of the radio frequency wiring between each movable plate of the group, and the purpose of adjusting the conducting length of the radio frequency wiring along with the telescopic state is further achieved.
Alternatively, a first end of the first movable plate 431 and a first end of the second movable plate 432 are respectively disposed at the first housing 41 and the second housing 42;
the contacts on the second segment of traces 462 on the second active board 432 in each set of active boards are disposed at a position near the second end of the second active board 432;
the contact arrangement positions on the first segment of the trace 461 on the first movable plate 431 in different sets of movable plates are different.
In one embodiment, the contacts may be disposed at the same fixed position on the traces of the movable plates on one side of the first housing 41 and the second housing 42, and the contacts may be disposed at different positions on the traces of the movable plates on the other side of the first housing 41 and the second housing 42, respectively, so as to ensure that different sets of movable plates can be connected through the contact on the rf traces in different telescopic states.
For example, as shown in fig. 6, the contacts a1 to a4 on the first trace segment on the four first movable plates 431 of the four movable plates are respectively disposed at different positions, and the contacts b1 to b4 on the second trace segment 462 on the four second movable plates 432 of the four movable plates are all disposed at the second end, so that when the retractable electronic device 40 is in the extended state, the contact a1 can be in contact with the contact b1, when the retractable electronic device 40 is retracted inward to a certain extent, the contact a2 can be in contact with the contact b2, when the retractable electronic device 40 is further retracted inward to a certain extent, the contact a3 can be in contact with the contact b3, and when the retractable electronic device 40 is in the retracted state, the contact a4 can be in contact with the contact b4, so that the rf connections between the rf module 44 and the antenna 45 can be achieved through the rf connections between the corresponding movable plates in four different retracted states.
Therefore, by the implementation mode, the radio frequency connection of the telescopic electronic equipment in different telescopic states can be realized by arranging the necessary contacts at the proper positions of the two sections of routing wires between each group of movable plates, the length of a radio frequency signal wire can be adjusted along with the distance between the radio frequency module and the antenna, and the circuit design is simple and easy to realize.
Alternatively, when N is equal to 2, the contact on the first segment of the trace 461 on the first movable plate 431 of the first set of movable plates is disposed at a position close to the first end of the first movable plate 431 thereof, and the contact on the first segment of the trace 461 on the first movable plate 431 of the second set of movable plates is disposed at a position close to the second end of the first movable plate 431 thereof.
That is, when the antenna structure of the retractable electronic device in the embodiment of the present application is designed using only two sets of movable plates, the radio frequency connection in both the extended and retracted states of the retractable electronic device 40 can be preferentially ensured. Specifically, under the condition that the contacts on the second section of trace 462 on the two second movable boards 432 are both disposed at the second ends of the trace, the contacts on the first section of trace 461 on the two first movable boards 431 are respectively disposed at the two ends of the trace, that is, the contact on the first section of trace 461 on one of the first movable boards 431 is disposed at the first end of the trace, and the contact on the first section of trace 461 on the other first movable board 431 is disposed at the second end of the trace. Thus, when the retractable electronic device 40 is in the extended state, the contact of the second end of the second section of the wire 462 disposed on the second movable plate 432 of the second housing 42 can contact the contact of the second end of the first section of the wire 461 disposed on the first movable plate 431 of the first housing 41, and when the retractable electronic device 40 is in the retracted state, the contact of the second end of the second section of the wire 462 disposed on the second movable plate 432 of the second housing 42 can contact the contact of the first end of the first section of the wire 461 disposed on the first movable plate 431 of the first housing 41.
Optionally, as shown in fig. 6, the radio frequency module 44 is connected to the first ends of the N radio frequency traces between the N sets of active plates through N radio frequency ports in a one-to-one correspondence manner;
the antenna 45 is connected with the second ends of the N radio frequency routing lines in a one-to-one correspondence manner through N antenna ports.
In one embodiment, the rf module 44 may have N rf ports, and the rf module 44 may be connected to the first ends of the N rf traces between the N sets of active boards through the N rf ports in a one-to-one correspondence manner, that is, each rf port is connected to the first end of one rf trace between one set of active boards.
The antenna 45 may have N antenna ports, and the antenna 45 may be connected to the second ends of the N rf traces between the N sets of active plates through the N antenna ports in a one-to-one correspondence manner, that is, each antenna port is connected to the second end of one rf trace between one set of active plates.
As shown in fig. 6, taking N equal to 4 as an example, the rf module 44 can be connected to the first trace 461 on the four first mobile boards 431 of the four sets of mobile boards through the port 1, the port 2, the port 3 and the port 4, respectively, and the antenna 45 can be connected to the second trace 462 on the four second mobile boards 432 of the four sets of mobile boards through the port 5, the port 6, the port 7 and the port 8, respectively. Thus, each time in a retracted state, rf module 44 may establish an rf connection with antenna 45 via one of the four wire channels.
Therefore, in the embodiment, the length of the radio frequency signal wire of the radio frequency module and the antenna in different telescopic states can be connected in an adjustable way through a simpler circuit design structure.
Optionally, as shown in fig. 7, the rf module 44 is connected to the immobile end of the first switch 48, and N immobile ends of the first switch 48 are respectively connected to the first ends of the N rf traces between the N sets of movable plates in a one-to-one correspondence;
and/or the antenna 45 is connected with the inactive end of the second switch 49, and the N inactive ends of the second switch 49 are respectively connected with the second ends of the N radio frequency cabling in a one-to-one correspondence manner.
Considering that in the embodiment shown in fig. 6, due to the scheme that the rf module and the antenna are directly connected to the rf trace, there exists an antenna extension line, for example, when the rf signal is transmitted to the antenna 45 from the channel corresponding to the port 1 to the port 5, then three extra rf lines corresponding to the ports 6, 7, and 8 are also present at the end of the antenna 45, thereby affecting the transmission efficiency of the antenna.

In the embodiment of the application, the comb tooth structure in the telescopic electronic equipment can be used as the connection of the radio frequency transmission line, the comb teeth are used as the transfer connection, a plurality of movable plates with required number can be selected from the comb teeth, and the radio frequency signal line adjustable connection between the radio frequency module and the antenna is realized by arranging the radio frequency connecting line and the contact on the movable plates. The following description will be made by referring to fig. 6 and 7 to illustrate an embodiment of the present application:
in the first embodiment, as shown in fig. 6, a1 contact, a2 contact, a3 contact and a4 contact are respectively disposed on the four first movable plates 431 at the positions shown in the figure, the rf module 44 is connected to the traces on the four first movable plates 431 through port 1, port 2, port 3 and port 4, respectively, the four second movable plates 432 are respectively disposed with b1 contact, b2 contact, b3 contact and b4 contact at the positions shown in the figure, and the antenna 45 is connected to the traces on the four second movable plates 432 through port 5, port 6, port 7 and port 8, respectively.
When the retractable electronic device 40 is fully deployed, the rf signal from the rf module 44 passes through port 1, contacts a1 and b1 to port 5, and is finally radiated through the antenna 45. And the analogy can be repeated to find the signal conduction path from the radio frequency module 44 to the antenna 45 when the telescopic electronic device 40 is contracted to the contact point a2 to contact point b2, the contact point a3 to contact point b3, and the contact point a4 to contact point b 4.
The positions of the contacts a1 to a4 can be determined according to the rotation of the reel gear of the retractable screen of the retractable electronic device 40, and the extension range of the retractable screen is determined by the number of rotation turns of the retractable screen, for example, when the rotation shaft rotates 20 turns, the retractable screen is completely unfolded, when the rotation shaft rotates 10 turns, the retractable screen extends to half of the size of the whole screen, and so on. The set positions of the contacts a1 to a4 can be determined by setting the rotation shaft to rotate to a plurality of turns, so the positions of the contacts a1 to a4 can be set according to requirements, for example, the first plate can be provided with a1 contact which is contacted with the b1 when the first plate is provided with 20 turns corresponding to the rotation shaft, the second plate can be provided with a2 contact which is contacted with the b2 when the second plate is provided with 15 turns corresponding to the rotation shaft, the third plate can be provided with a3 contact which is contacted with the b3 when the third plate is provided with 10 turns corresponding to the rotation shaft, and the fourth plate can be provided with a4 contact which is contacted with the b4 when the rotation shaft does not rotate, wherein the contacts b1 to b4 can be provided at the second end of the respective second plates. Of course, the number of the movable plates and the arrangement density of the contacts can be increased according to actual requirements so as to meet the radio frequency functions in more telescopic states.

When the telescopic screen is fully expanded, the first switch 48 can be switched to the port 1, and the second switch 49 can be switched to the port 5, so that the radio frequency signal passes through the port 1, the contact a1 and the contact b1, and finally is conducted to the antenna 45 end through the port 5, wherein the contacts on the other movable plates which are not contacted are not conducted. And the analogy can be repeated, when the telescopic screen contracts to the contact point a2 to contact with the contact point b2, the contact point a3 to contact point b3, the contact point a4 to contact point b4, the ports conducted by the first switch 48 and the second switch 49, and the signal conduction path from the radio frequency module 44 to the antenna 45.

Therefore, the length of the radio-frequency signal line between the antenna and the radio-frequency module can be adjusted along with the different telescopic states of the telescopic electronic equipment, so that the attenuation of radio-frequency signals in the transmission process can be reduced, and the transmission efficiency of the antenna is improved.
