The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Communication terminals arranged to communicate over a wireless interface may be referred to as "wireless communication terminals", "wireless terminals" and/or "mobile terminals", "electronic devices". Examples of electronic devices include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The embodiment of the application provides an electronic device, which comprises a first electronic component, a second electronic component and an electronic assembly; the second electronic component can be connected with the first electronic component in a sliding mode, and the second electronic component can slide relative to the first electronic component by controlling the movement of the second electronic component, so that the second electronic component is contained in the first electronic component or protrudes out of the first electronic component. The electronic component comprises a mainboard and an antenna component. The main board is disposed in the first electronic component, which may be a control center of the electronic device. The antenna assembly comprises a radio frequency module, an antenna radiator and a radio frequency line, the radio frequency module is arranged on the mainboard, the antenna radiator is arranged on the second electronic component, the radio frequency line is electrically connected between the radio frequency module and the antenna radiator, and when the second electronic component slides relative to the first electronic component, the radio frequency line can be driven to stretch or bend and retract. The control center of the electronic device is used for adjusting the position of the second electronic component relative to the first electronic component according to the performance index of the antenna radiator, so that a relatively large antenna clearance area is kept around the antenna radiator, and the antenna radiation efficiency of the electronic device can be improved.
In the course of research, the inventors found that, in order to ensure the reliability of the connection of the rf line, a sufficient redundant length needs to be reserved for the rf line, so that the rf line can still maintain the reliable connection between the antenna radiator and the rf module when the second electronic component is relatively far away from the first electronic component. However, when the second electronic component slides toward the first electronic component, the quality of the radio frequency line connection in the antenna assembly is affected and the antenna radiation performance is not ideal. Therefore, in the present invention, the inventors have focused on the cause of insufficient connection quality of the radio frequency line and the improvement method.
In the course of the above studies, the inventors' studies included: analyzing the connection quality of radio frequency lines with different lengths and the influence of the connection quality on the radiation performance of the antenna; analyzing the influence of different connection structures on the connection quality of the radio frequency wire and the radiation performance of the antenna under the same length of the radio frequency wire; and analyzing the influence of different mounting structures on the connection quality of the radio frequency wire and the radiation performance of the antenna under the same length of the radio frequency wire, and the like. After a great deal of research and analysis, the inventor finds that: in the electronic device, the radio frequency line needs to reserve enough redundant length to ensure the connection quality of the antenna, the overlong radio frequency line is easy to wind, bend or even break, and the winding and bending conditions of the radio frequency line are different by adopting different mounting structures. In view of the above situation, the inventor further finds that, when the rf wire has a suitable redundant length, the winding and bending conditions of the rf wire can be effectively improved by guiding the moving direction of the rf wire during the process of bending and retracting the rf wire.
In view of the above problems, embodiments of the present invention provide the electronic device to improve the insufficient connection quality of the rf cable.

Referring to fig. 6, in some embodiments, in order to further improve the anti-entanglement effect of the rf wire 365, the rf wire 365 is movably wound around the outer circumference of the balloon 44, and when the balloon 44 is inflated, the winding radius of the rf wire 365 is increased, so that the extending length of the rf wire 365 is shortened, thereby being capable of adapting to the movement of the second electronic component 20 toward the first electronic component 20 to prevent the rf wire 365 from being entangled by itself.
Further, the airbag 44 is provided with a guide groove 441 at the outer circumference, the guide groove 441 is spirally arranged, and the rf line 365 is at least partially accommodated in the guide groove 441 and can move along the extending direction of the guide groove 441. In some embodiments, a limiting member 443 is further disposed on the balloon 44, and the limiting member 443 is used to limit the approximate position of the rf line 365. Specifically, the limiting member 443 spans over the guide slot 441, two ends of the limiting member 443 are respectively connected to two sides of the guide slot 441, the radio frequency line 365 is located between the limiting member 443 and the bottom of the guide slot 441, and the limiting member 443 can ensure that the radio frequency line 365 is movably accommodated in the guide slot 441 and is not easily separated from the guide slot 441 when the airbag 44 inflates or deflates. Further, in some embodiments, the bottom of the guide groove 441 is provided with a roller (not shown in the figures), and when the rf wire 365 moves in the guide groove 441 relative to the air bag 44, the rf wire 365 contacts the roller. Through setting up the roller, the frictional force when can reducing the motion of radio frequency line 365 makes the removal of radio frequency line 365 more smooth, can reduce the friction damage of radio frequency line 365 simultaneously, prolongs the life of radio frequency line 365.
It will be appreciated that in some embodiments, the guiding groove 441 may be omitted, and the rf line 365 may be directly and movably disposed around the outer circumference of the airbag 44, and the position of the rf line 365 may be limited by the limiting component 443. At this time, two ends of the limiting member 443 are respectively connected to the air bag 44, and the rf line 365 passes through between the limiting member 443 and the air bag 44. Even more, in some embodiments, the retaining member 443 can be omitted, and the rf wire 365 can be directly and movably disposed around the outer circumference of the airbag 44, so that the rf wire 365 contracts with the expansion of the airbag 44 or expands with the contraction of the airbag 44.
Further, in order to prevent the connection between the rf line 365 and the rf module 361 from loosening, the electronic apparatus 100 may further include a fixing member 49, and the fixing member 49 is disposed on the mounting member 16 and is used for fixing the rf line 365. In the embodiment shown in fig. 5, the fixing member 49 is disposed adjacent to the rf module 361, and a portion of the rf wire 365 between the portion held by the fixing member 49 and the joint connected to the rf module 361 is in a fixed state relative to the mounting member 16, and when the rf wire 365 is extended or contracted, the portion is in a static state relative to the first electronic component 10, so as to ensure that the connection between the rf wire 365 and the rf module 365 is not loosened by the movement of the rf wire 365, thereby improving the reliability of the connection of the rf wire 365. It is understood that in other embodiments, a similar fixing member (not shown) may be disposed at an end of the rf wire 365 connected to the antenna radiator 363 to ensure that the connection between the rf wire 365 and the antenna radiator 363 is not loosened by the movement of the rf wire 365, thereby improving the reliability of the connection of the rf wire 365.
When the electronic device 100 is used, when the second electronic component 20 is relatively far away from the first electronic component 10, the second electronic component 20 drives the rf line 365 to stretch, and simultaneously drives the first pressing portion 4213 of the push rod 421 to move toward the first stopper 47, so as to press the air bag 44, and allow the gas in the air bag 44 to enter the gas storage bag 423, thereby making room for stretching the rf line 365. When the second electronic component 20 is relatively close to the first electronic component 10 and retracts into the first electronic component 10, the second electronic component 20 drives the rf line 365 to retract, and simultaneously drives the second pressing portion 4215 of the push rod 421 to move towards the second stopper 48, so as to press the gas storage bag 423, so that the gas in the gas storage bag 423 enters the gas bag 44, the gas bag 44 expands and occupies the space of the rf line 365, and the rf line 365 moves towards a preset direction, so as to obtain a relatively determined motion track.

The electronic equipment further comprises an inflating mechanism, wherein the inflating mechanism comprises an air bag and an inflating piece, the air bag is arranged in the first electronic component, and the inflating piece is connected to the air bag; when the second electronic component slides in relative to the first electronic component, the inflating piece is triggered to inflate the air bag, and the air bag expands and occupies the space of the radio frequency wire so that the radio frequency wire moves towards the preset direction. Based on the electronic equipment, the control method can comprise the following steps:
step S101: and detecting the performance index of the antenna radiator.
Further, when detecting the performance index of the antenna radiator, the performance index includes any one of the following parameter indexes: standing wave ratio, radiation efficiency, reflected power, return loss.

Therefore, in step S105, the relative position between the second electronic component and the first electronic component is obtained, and if the second electronic component is determined not to be located at the second limit position relative to the first electronic component, the second electronic component is controlled to slide to the second limit position in the direction approaching the first electronic component, and at this time, the second electronic component is accommodated in the first electronic component; and if the second electronic component is judged to be in the second limit position relative to the first electronic component, keeping the current position of the second electronic component unchanged.

Step S111: the second electronic component is controlled to slide to an intermediate position relative to the first electronic component.
Further, in some embodiments, before controlling the second electronic component to slide, the relative position of the second electronic component and the first electronic component is acquired, and if the second electronic component is not in the middle position, the second electronic component is controlled to slide to the middle position; if the second electronic component is already in the intermediate position, the current position of the second electronic component is kept unchanged. Further, when the second electronic component slides, the inflating part is triggered to inflate the air bag or exhaust the air in the air bag so as to guide the radio frequency wire to retract or allow the radio frequency wire to extend.
