as shown in fig. 5, the radio frequency traces include a first segment of trace 461 located on the first movable board 431 and a second segment of trace 462 located on the second movable board 432, the first segment of trace 461 is provided with one contact, the second segment of trace 462 is provided with at least two contacts, and the first movable board 431 and the second movable board 432 are two adjacent movable boards;

when the first movable plate 431 and the second movable plate 432 move along with the expansion and contraction of the retractable electronic device 40, the contact on the first section of the trace 461 is in contact with different contacts on the second section of the trace 462, and the conduction length of the rf trace is different along with the contact between the different contacts.

In the embodiment of the present application, as shown in fig. 4, the telescopic electronic device 40 has a first housing 41 and a second housing 42, and a plurality of movable plates 43 are alternately disposed between the first housing 41 and the second housing 42 to form a comb structure, and as shown in fig. 4, the first housing 41 and the second housing 42 can move relatively and drive the movable plates 43 disposed between the first housing 41 and the second housing 42 to move along, so that the telescopic electronic device 40 is contracted or expanded, specifically, the first housing 41 and the second housing 42 are respectively disposed on two sides of the telescopic electronic device 40, and one of the two adjacent movable plates is disposed on the first housing 41, and the other one is disposed on the second housing 42, and the two movable plates can move toward or away from an opposite side along with the extension and retraction of the telescopic electronic device 40.

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 contacts arranged at different positions on the radio frequency trace.

Specifically, as shown in fig. 5, the first movable panel 431 and the second movable panel 432 are two adjacent movable panels, and the rf trace between the two movable panels includes a first segment of trace 461 located on the first movable panel 431 and a second segment of trace 462 located on the second movable panel 432, wherein a first end of the first segment of trace 461, that is, an end close to the first housing 41, is connected to the rf module 44, and a first end of the second segment of trace 462, that is, an end close to the second housing 42, is connected to the antenna 45. The first section of wire 461 is provided with a contact, the second section of wire 462 is provided with at least two contacts, the first movable plate 431 and the second movable plate 432 can move along with the expansion and contraction of the telescopic electronic device 40, and further can be located at different relative positions in different expansion and contraction states, the first section of wire 461 can contact with different contacts on the second section of wire 462 through the contacts when the first movable plate 431 and the second movable plate 432 are located at different relative positions, so as to realize the electrical connection between the first section of wire 461 and the second section of wire 462, and can have different lengths of radio frequency signal wires when different contacts are contacted, so that the radio frequency conduction distance between the radio frequency module 44 and the antenna 45 can adapt to change along with the expansion and contraction of the telescopic electronic device 40. The contact may be a spring or other metal conductive sheet.

Specifically, when the retractable electronic device 40 is in the retracted state, a conducting distance from the first end of the first wire 461 to the first end of the second wire 462 (i.e. a length of the rf signal line between the rf module 44 and the antenna 45) is smaller than a conducting distance from the first end of the first wire 461 to the first end of the second wire 462 when the retractable electronic device 40 is in the extended state, that is, when the retractable electronic device 40 is in different retracted states, the length of the rf signal line between the rf module 44 and the antenna 45 can be flexibly changed along with a change of a linear distance therebetween.

Assuming that 1 contact, which is an a contact, is disposed on the first section of trace 461, and two contacts, which is a b contact and a c contact, are disposed on the second section of trace 462 at different positions, respectively, such that when the retractable electronic device 40 is in the extended state, the first movable plate 431 is close to the second movable plate 432 toward the second end of the first housing 41 toward the second end of the second housing 42, so that the a contact on the first section of trace 461 can contact with the b contact on the second section of trace 462, at this time, the length of the rf signal line between the rf module 44 and the antenna 45 is long, when the retractable electronic device 40 is in the retracted state, the second end of the first movable plate 431 is close to the first end of the second movable plate 43, so that the a contact on the first section of trace 461 can contact with the c contact on the second section of trace 462, at this time, the length of the rf signal line between the rf module 44 and the antenna 45 is short, the attenuation of the radio frequency signal in the transmission process can be reduced. Certainly, another contact may be disposed on the first section of trace 461 at the middle position, and the c contact on the second section of trace 462 may also be disposed at the middle position of the trace, so that when the retractable electronic device 40 is in the retracted state, the two sections of traces may also be electrically connected through the contact at the middle position.

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.

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;

a first contact is disposed on the first segment of trace 461 near the second end of the first movable plate 431.

That is, one end, e.g., the first end, of the first movable plate 431 is disposed on the first housing 41, one end, e.g., the first end, of the second movable plate 432 is disposed on the second housing 42, i.e., one end of the first movable plate 431 is fixed to one side housing of the retractable electronic device 40, one end of the second movable plate 432 is fixed to the other side housing of the retractable electronic device 40, and the other ends of the first movable plate 431 and the second movable plate 432 are in a movable state.

In this embodiment, a contact may be disposed on the first wire 461 near the second end of the first movable plate 431, so as to ensure that the contact on the first wire 461 can contact with the second wire 462 in a corresponding telescopic state no matter where the contact on the second wire 462 is disposed.

Optionally, a second contact is disposed on the second segment of the trace 462 near the first end of the second movable plate 432, and a third contact is disposed on the second segment of the trace 462 near the second end of the second movable plate 432;

when the retractable electronic device 40 is in the retracted state, the first movable plate 431 and the second movable plate 432 are close to each other, the first contact is in contact with the second contact, when the retractable electronic device 40 is in the extended state, the first movable plate 431 and the second movable plate 432 are away from each other, the first contact is in contact with the third contact, and the conduction length of the radio frequency trace in the retracted state is smaller than the conduction length in the extended state.

In one embodiment, in order to ensure the rf signal transceiving function of the retractable electronic device 40 in the extended and retracted states, a contact may be disposed at each of two ends of the second section of wire 462, specifically, a second contact is disposed on the second section of wire 462 near the first end of the second movable plate 432, and a third contact is disposed on the second section of wire 462 near the second end of the second movable plate 432.

When the retractable electronic device 40 is in the retracted state, the first movable plate 431 and the second movable plate 432 are close to each other, the first contact on the first segment of the trace 461 is in contact with the second contact on the second segment of the trace 462, when the retractable electronic device 40 is in the extended state, the first movable plate 431 and the second movable plate 432 are away from each other, the first contact on the first segment of the trace 461 is in contact with the third contact on the second segment of the trace 462, and the conduction length between the first segment of the trace 461 and the second segment of the trace 462 in the retracted state is smaller than the conduction length in the extended state.

For example, as shown in fig. 5 and fig. 6, a contact a is disposed at the second end of the first wire 461, and a contact b and a contact c are disposed at the first end and the second end of the second wire 462, respectively, so that in a process that the retractable electronic device 40 is moved from the extended state to the retracted state, the contact a on the first wire 461 is sequentially contacted with the contact b and the contact c on the second wire 462, and it is ensured that the first wire 461 and the second wire 462 can be connected in the extended and retracted states, and have different lengths of the rf signal lines.

Therefore, through the implementation mode, the radio frequency connection of the telescopic electronic equipment in the expansion and contraction states can be realized by arranging a small number of necessary contacts at proper positions on the two sections of routing wires, and the length of the radio frequency signal wire can be adjusted along with the distance between the radio frequency module and the antenna.

Optionally, M contacts are further disposed on a portion of the second segment of trace 462 between the second contact and the third contact, where M is a positive integer.

That is, in another embodiment, the second segment of the trace 462 may be provided with a plurality of contacts, and besides two ends of the second segment of the trace 462 are respectively provided with one contact, other contacts may be further provided between the first end and the second end of the second segment of the trace 462, and in order to achieve the purpose that the telescopic electronic device 40 can achieve better radio frequency performance in various expansion and contraction states, the arrangement density of the contacts on the second segment of the trace 462 may be increased.

Wherein, when the retractable electronic device 40 is in the retracted state of different degrees, the first contact is respectively contacted with different contacts on the second segment of trace 462.

Thus, according to actual requirements, a plurality of contacts can be arranged at appropriate positions of the second section of wiring 462 so as to realize radio frequency connection of the telescopic electronic equipment in different telescopic states, and the length of the radio frequency signal line can be adjusted along with the distance between the radio frequency module and the antenna.

Optionally, the M contacts are uniformly spaced on the second segment of trace 462 between the second contact and the third contact.

That is, for the second section of the wire 462 requiring to arrange a plurality of contacts, except that two contacts are respectively arranged at the first and last sections of the second section of the wire 462, the M contacts can be arranged at even intervals between the two ends of the second section of the wire 462, and the distance interval between every two adjacent contacts is guaranteed to be basically consistent, so that a user can conveniently control the telescopic electronic device 40 to be in telescopic states of different degrees according to the even interval distance between the contacts, and can obtain better radio frequency performance in different telescopic states.

For example, as shown in fig. 7, the second end of the first segment of trace 461 is provided with one contact, i.e., a-contact, and N contacts, i.e., b1 contact, b 2-bn contact, are uniformly arranged between the first end and the second end of the second segment of trace 462.

Optionally, the contact on at least one of the first section of trace 461 and the second section of trace 462 has a protrusion.

In an embodiment, the contact on at least one of the rf traces between two adjacent active boards has a protruding structure, so as to ensure that two segments of traces can achieve better contact through the protruding structure on the contact, in practical applications, the contact with the protrusion may be disposed on one segment of trace with fewer contacts, for example, as shown in fig. 8a and 9a, only the contact a with the protrusion may be disposed on the first segment of trace 461.

Optionally, the number of the contacts arranged on the second segment of trace 462 is N, where N is an integer greater than or equal to 2;

the second segment of traces 462 includes N +1 portions of traces, and every two adjacent portions of the N +1 portions of traces are connected by one contact;

when the contact on the first segment of trace 461 contacts with the target contact on the second segment of trace 462, the target contact is jacked up, so that the two segments of traces connected by the target contact are disconnected, and the target contact is any one of the N contacts on the second segment of trace 462.

In one embodiment, the second segment of traces 462 with N contacts can be formed by connecting N +1 portions of traces through contacts, that is, one contact is disposed between every two adjacent portions of traces, and the contact can connect two adjacent portions of traces.

When the contact on the first trace 461 contacts with a certain contact on the second trace 462, the contact on the second trace 462 can be lifted up, so that two portions of the trace at the contact are disconnected, that is, the second trace 462 can be disconnected at the lifted-up contact, and then a portion of the trace connected to the antenna 45 is connected to the first trace 461.

For example, as shown in fig. 9a, the second segment of trace 462 includes N +1 portions of traces, where the N +1 portions of traces are connected by N contacts, and each two adjacent portions of traces are connected by one contact; when the a contact on the first section of trace 461 is in contact with the bn contact on the second section of trace 462, the bn contact is lifted up, so that the second section of trace 462 is disconnected at the bn contact, the first section of trace 461 is connected with a part of trace between the bn contact of the second section of trace 462 and the first end of the second section of trace 462 through the a contact, that is, the length of the effective rf signal line is almost equal to the distance between the current rf module 44 and the antenna 45.

Thus, by this embodiment, the length of the effective rf signal line between the rf module 44 and the antenna 45 can be ensured to be the shortest length, and there is no extra rf trace affecting the transmission efficiency of the rf signal.

Alternatively, as shown in fig. 6 and 7, the first segment of the trace 461 is disposed on the side of the first movable panel 431 facing the second movable panel 432, and the second segment of the trace 462 is disposed on the side of the second movable panel 432 facing the first movable panel 431.

In one embodiment, in order to ensure that the rf traces between the first movable board 431 and the second movable board 432 can be reliably contacted through the contacts, one segment of trace may be disposed on each of two opposite sides of the two movable boards, and when the two movable boards approach or depart from the retractable electronic device 40, the contacts at the corresponding positions on the two sides can be easily contacted with each other, so that the two segments of trace on the two sides are connected through the contacted contacts.

For example, as shown in fig. 6, in one embodiment, the first movable board 431 is provided with a first segment of trace 461 on the side facing the second movable board 432, and the right end of the first segment of trace 461 is disposed with an a contact, the second movable board 432 is provided with a second segment of trace 462 on the side facing the first movable board 431, and the left and right ends of the second segment of trace 462 are disposed with a b contact and a c contact, respectively. In a further embodiment, as shown in fig. 7, b1 contacts, b2 contacts to bn contacts are uniformly arranged on the second section of traces 462, and the rf traces and contacts on the side of the first movable plate 431 are arranged as shown in fig. 6.

It should be noted that a proper gap may be reserved between the first movable plate 431 and the second movable plate 432, a jacking and rebounding space of the contact is reserved, and the two segments of the traces between two adjacent movable plates may be prevented from being pressed against each other.

Optionally, a tuning device 47 is further disposed between the rf module 44 and the antenna 45.

As shown in fig. 8a and 9a, a tuning device 47 for adjusting the frequency of the radio frequency signal may be further disposed between the radio frequency module 44 and the antenna 45, so that the telescopic electronic device 40 may be adjusted to the operating frequency matched with the current state through the tuning device 47 according to the length of the radio frequency signal line in different telescopic states, and the whole radio frequency system may maintain stable performance under different lengths of the radio frequency signal line.
