Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, in the embodiments of the present application, features in the embodiments and the examples may be arbitrarily combined with each other without conflict.

Referring to fig. 1 (a) to fig. 1 (c), the electronic device 100 according to the embodiment of the present disclosure includes, but is not limited to, a mobile terminal such as a mobile phone and a tablet, or other portable electronic devices, and herein, the electronic device 100 is taken as a mobile phone for example.

In this embodiment, the housing 10 includes a first portion 12 and a second portion 14, the first portion 12 and the second portion 14 being capable of relative movement. Specifically, in the present embodiment, the first portion 12 and the second portion 14 are slidably coupled, that is, the second portion 14 is slidable relative to the first portion 12.

In one embodiment, the first portion 12 may be substantially rectangular in shape, and the first portion 12 forms a receiving space for receiving a scroll screen, wherein the scroll screen includes the scroll 20 and the flexible display screen assembly 30, and may also be used for stacking other electrical components of the electronic device 100, such as a battery, a sub-board, wherein the sub-board may be used for disposing electrical components of a speaker and a microphone of the electronic device 100.

The first portion 12 includes a top frame 122, the top frame 122 defines a first opening 1222 and a second opening 1224, and the first opening 1222 and the second opening 1224 are both in communication with the accommodating space 120. The opening direction of the first opening 1222 is perpendicular to the direction of the second opening 1224. The first opening 1222 is used for passing an end of the flexible display screen assembly 30 to connect the end of the flexible display screen assembly 30 with the reel 20, and the second opening 1224 is used for exposing the driving mechanism 70 from the accommodating space 120 to connect with the second portion 12.

Specifically, in the present embodiment, the first opening 1222 may be opened along a longitudinal direction of the electronic device 100, and the second opening 1224 may be opened along a lateral direction of the electronic device 100. The number of the second openings 1224 may be two, and the two second openings 1224 are located at both sides of the first top plate 122 and are symmetrically arranged in the longitudinal direction. The second portion 14 is movable relative to the first portion 12 in a lateral direction of the electronic device 100. In addition, the first portion 12 defines a sliding slot 124, and the sliding slot 124 is configured to cooperate with the second portion 14 to enable the second portion 14 to slide relative to the first portion 12.

In the present embodiment, when the first portion 12 and the second portion 14 move towards each other to the limit position, the first portion 12 and the second portion 14 are integrally formed into a substantially rectangular housing 10. As the first portion 12 and the second portion 14 move apart (i.e., away from each other), the second portion 14 moves away from the first portion 12.

The reel 20 is rotatably disposed in the first portion 12, and specifically, the reel is rotatably disposed in the accommodating space. That is, the spool 20 is mounted to the first portion 12 and is rotatable relative to the first portion 12. The roller 20 is adapted to be coupled to the driving mechanism 70 such that the roller 20 can be rotated relative to the first portion 12 to release or retract the flexible display screen assembly 30 under the driving of the driving mechanism 70 such that the roller screen has a first state and a second state, wherein the first state has a smaller deployment area than the second state.

It will be appreciated that the rotational positioning of the spool 20 on the first portion 12 may refer to the spool 20 being mounted directly on the first portion 12, or may refer to the spool 20 being mounted on the first portion 12 via other media.

One end of flexible display screen assembly 30 is fixedly attached to second portion 14, and in this embodiment, the end is fixedly attached to second portion 14, and in other embodiments, the end may be attached to second portion 14 via a movable mechanism, such as a mechanism for adjusting the tension of flexible display screen assembly 30. The other end of the flexible display screen assembly 30 is positioned on the spool 20 such that a portion of the flexible display screen assembly 30 may be wound onto the spool 20. The roller 20 may be used to take up the flexible display screen assembly 30 and release the flexible display screen assembly 30. Wherein upon a movement of the first and

second portions

12, 14 away from each other, the roller 20 is able to rotate to release the flexible display screen assembly 30, thereby expanding the display portion 301 of the flexible display screen assembly 30. Specifically, one end of the flexible display screen assembly 30 is fixedly connected to the second portion 14, and the other end thereof passes through the first opening 1222 of the first portion 12 and then is connected to the winding shaft 20 disposed in the accommodating space 120.

In this manner, upon a movement of the first and

second portions

12, 14 away from each other, the spool 20 can rotate to release the flexible display screen assembly 30, thereby expanding the display portion 301 of the flexible display screen assembly 30. Therefore, the size of the screen display area of the electronic device 100 can be freely adjusted, the display part 301 of the flexible display screen assembly 30 can be expanded to improve the operation experience of a user when a large screen is needed, and meanwhile, the display part 301 can not be expanded when the large screen is not needed, so that the whole device is small in size and convenient to carry.

It will be appreciated that in one instance, the first portion 12 and the second portion 14 are connected together in close proximity, in which case the display portion 301 of the flexible display screen assembly 30 is not expanded and the electronic device 100 is in a narrow screen mode, in which a portion of the flexible display screen assembly 30 is rolled onto the roller 20 and a portion is positioned above the first top panel 122 and exposed from the housing 10 for display. It should be noted that in the present embodiment, the "display portion 301 of the flexible display panel assembly 30" may be understood as a portion located above the second top board 142 of the second portion 14, that is, a portion exposed from the housing 10.

When the display portion 301 of the flexible display screen assembly 30 needs to be expanded, the first portion 12 and the second portion 14 move away from each other, so that the second portion 14 drives the flexible display screen assembly 30 to extend, and at this time, the reel 20 can release the flexible display screen assembly 30, so that the display portion 301 of the flexible display screen assembly 30 is enlarged, and further, the operation experience and the demand of a user are improved. In such a case, the electronic device 100 is in the extended mode.

It will be appreciated that there are extreme positions in which the display area of the electronic device 100 is maximized, i.e. the area of the set of flexible display screens 32 exposed from the housing 10 is maximized, i.e. the area of the display portion 301 of the flexible display screen assembly 30 is maximized, when both the second part 14 and the first part 12 are moved away from each other. When the first portion 12 and the second portion 14 are brought into close and coupled fit together, the display area of the electronic device 100 is minimized, i.e., the display portion 301 of the flexible display screen assembly 30 is minimized in area.

In this embodiment, one end of the flexible display screen assembly 30 is fixedly connected to the second portion 14, which may mean that one end of the flexible display screen assembly 30 is directly fixed to the second portion 14, or that the flexible display screen assembly 30 is fixed to the second portion 14 through another medium. One end of the flexible display screen assembly 30 is not movable relative to the second portion 14.

Fig. 2 (a) is a schematic structural diagram of the electronic device 100 with the antenna device 40 mounted thereon. As shown in fig. 2, the electronic device 100 further includes an antenna assembly 40, where the antenna assembly 40 includes an antenna radiator 42 and a feed 44, and the feed 44 is connected to the antenna radiator 42 through a matching network. When the scroll screen is switched from the first state to the second state, the antenna radiator 42 does not move synchronously with the scroll screen, that is, by setting the antenna radiator 42 not to move synchronously with the scroll screen, when the scroll screen is switched between the first state and the second state, the position of the antenna radiator 42 does not change, and the stability of the performance of the antenna device 40 is ensured; in addition, the antenna radiator 42 does not have a change in physical shape, and thus does not affect the performance of the antenna radiator 42. And the matching network can carry out impedance matching according to the position of the scroll screen so as to enable the antenna radiator to work in different frequency bands. That is to say, when the scroll screen moves to a certain position, the matching network adjusts the matching parameters to enable the scroll screen to work in a certain frequency band, and when the antenna radiator moves to another position along with the scroll screen, the matching network adjusts the matching parameters again to enable the antenna radiator to work in another frequency band, so that low frequency, medium frequency and high frequency can be realized by using a single antenna radiator, and different use scenes can be met.

In some embodiments of the present application, the matching network may include a plurality of matching paths, and matching parameters of each matching path are different, for example, the matching network includes a first matching path, a second matching path, and a third matching path, which correspond to a low frequency, an intermediate frequency, and a high frequency, respectively, and thus, the matching network may select any one of the matching paths to be conducted through a switch, so as to implement impedance matching, and enable the antenna radiator to operate in a corresponding frequency band.

In other embodiments of the present application, the matching network may also be an adjustable matching network, for example, the matching network includes devices such as an adjustable capacitor, and impedance matching may also be implemented by adjusting parameters of the devices such as the adjustable capacitor, so that the antenna radiator may operate in a corresponding frequency band.

In the embodiment of the present application, the material used for the antenna radiator is a flexible conductive material, and includes but is not limited to a flexible circuit board, a metal sheet, and the like.

In this embodiment, the antenna radiator 42 is disposed on the first portion 12.

Since the second part 14 is slidable relative to the first part 12, this means that the first part 12 is fixed relative to the slidable second part 14, so that the antenna radiator 41 does not move synchronously with the reel screen.

The housing 10 includes a stand for supporting the electronic device and a middle frame of the electronic device; the middle frame can be made of metal.

The antenna radiator may be disposed on the middle frame.

In this embodiment, the first portion 12 includes a top rim 122 and a bottom rim 126 that are oppositely disposed and a side rim 128 that is located between the top rim 122 and the bottom rim 126. The antenna radiator 42 is disposed on the side frame 128.

Since the antenna radiator 42 is disposed on the side frame 128, the length direction of the antenna radiator 42 is perpendicular to the sliding direction, when the state of the scroll screen of the electronic device 100 changes, the position of the antenna radiator 42 relative to the side frame 128 will not change, and the radiation performance of the antenna device 40 will not be affected.

Taking the case that the antenna device 40 supports the WIFI 2.4G frequency band as an example, if one end of the antenna radiator 42 is adjacent to the middle position of the side frame 128, when the user holds the electronic device 1000 across the screen, the situation that the antenna device 40 is held can be reduced, and the radiation efficiency of the antenna device 40 to the WIFI 2.4G frequency band is ensured; on the contrary, if the antenna radiator 42 is disposed on the top frame 122 or the bottom frame 126, and one end of the antenna radiator 42 is adjacent to the middle position of the top frame 122 or the bottom frame 126, when the reel screen of the electronic device 100 is switched from the first state to the second state, since the second portion 14 moves away from the first portion 12, one end of the antenna radiator 42 will be away from the middle position of the top frame 122 or the bottom frame 126, when the user holds the electronic device 1000 across the screen, the antenna device 40 is easily held by the user, so as to reduce the radiation efficiency of the antenna device 40 on the WIFI 2.4G frequency band.

Further, the antenna radiator 42 includes at least two radiators, wherein a gap exists between ends of adjacent radiators.

One of the at least two radiators is provided with a feed point for connecting with a feed source, and the other radiators can be coupled with the tail end of the radiator by utilizing the tail end, so that the current signals are transmitted on the other radiators. In addition, the other end of the other radiator may be used as a ground terminal or a free terminal.

Fig. 2 (b) is a schematic diagram of the antenna device 40. As shown in fig. 2 (b), the antenna radiator 42 includes, for example, a first radiator 421 and a second radiator 422, where:

the first radiator 421 has two ends, a first ground end 21a and a first coupling end 21b. In one embodiment, the first ground terminal 21a and the first coupling terminal 21b are opposite ends of the first radiator 421 in a straight line shape. In other embodiments, the first radiator 421 has a bent shape, and the first ground terminal 21a and the first coupling terminal 21b are not opposite to each other along a straight line.

The second radiator 422 has two ends, namely a second coupling end 22a and a free end 22b, and a feeding point a located between the two ends. A coupling gap exists between the second coupling end 22a and the first coupling end 21b. The first radiator 421 and the second radiator 422 can generate capacitive coupling through the coupling slot 220. Alternatively, the first radiator 421 and the second radiator 422 may be arranged along a straight line or substantially along a straight line (i.e., with a small tolerance in the design process). In other embodiments, the two ends of the second radiator 422 may be a coupling end and a ground end.

The first coupling end 21b is opposite to the second coupling end 22a and spaced apart from the second coupling end. The coupling slot 220 is a broken slot between the first radiator 421 and the second radiator 422, for example, the width of the coupling slot 220 may be 0.5-2 mm, but is not limited to this size. The first radiator 421 and the second radiator 422 can be regarded as two portions formed by the antenna radiator 42 being separated by the first coupling slot 220.

The first radiator 421 and the second radiator 422 are capacitively coupled through the coupling slot 220. The term "capacitive coupling" refers to that an electric field is generated between the first radiator 421 and the second radiator 422, a signal of the first radiator 421 can be transmitted to the second radiator 422 through the electric field, and a signal of the second radiator 422 can be transmitted to the first radiator 421 through the electric field, so that the first radiator 421 and the second radiator 422 can achieve electrical signal conduction even in a state of no direct contact or no direct contact.

Fig. 2 (c) is a schematic diagram of the ground reference GND of the electronic device 100. As shown in fig. 2 (c), the ground reference GND includes a first side 61 and a second side 62 which are oppositely disposed, and a third side 63 and a fourth side 64 which are connected between the first side 61 and the second side 62. The first side 61 is a top side of the ground GND (with reference to a state where the user holds the electronic device 100 in a vertical screen) and the second side 62 is a bottom side of the ground GND.

Due to the long length of the antenna radiator, there may be formed a ring mode or other inefficient noise between the antenna radiator and the ground GND. The position where the current intensity is the maximum may be selected as the setting position of the slot according to the current intensity of the clutter to suppress the clutter interference, thereby ensuring the signal quality of the antenna device 40.

In this embodiment, the feed source 44 does not move synchronously with the scroll screen to reduce the complexity of the structural design of the antenna device.

If the feed source 44 moves synchronously with the scroll screen and the antenna radiator 42 does not move synchronously with the scroll screen, the distance between the feed source 44 and the antenna radiator 42 is not fixed, and therefore, when the feed source 44 is connected with the antenna radiator 42, the wiring layout is very complicated. If the antenna radiator 42 and the feed source 44 do not move synchronously with the scroll screen, the distance between the antenna radiator 42 and the feed source 44 is fixed, and when the feed source 44 is connected with the antenna radiator 42, the complexity of wiring layout can be reduced.

As shown in fig. 2 (a), the side frame 128 is provided with a feeding portion and a grounding portion, the feeding portion and the grounding portion are respectively connected to the antenna radiator, the output end of the matching network is connected to the feeding portion, and the grounding portion is grounded.

Specifically, the feeding portion and the grounding portion may be disposed on a circuit board fixed in the accommodating space of the housing 10, and the feeding portion and the grounding portion are connected to the antenna radiator 42 during the movement of the scroll screen, so as to ensure that the antenna device 40 can work normally in different usage scenarios. The output end of the matching network is connected with the feed part, so that the feed source outputs signals, the signals are transmitted to the antenna radiator through the matching network and the feed part, and the grounding part is grounded.

When the reel screen is switched between the first state and the second state, the feeding portion is kept electrically connected with the feeding point, and the grounding portion is also kept electrically connected with the first grounding point A. That is, the feeding portion and the grounding portion are not located at the same position on the first portion 12, and the feeding point and the grounding point are located at the same position on the antenna radiator 42, and the feeding portion is always electrically connected to the feeding point on the antenna radiator 2 and the grounding portion is also always electrically connected to the grounding point a on the antenna radiator 42 during the sliding of the spool panel, so that the resonant frequency of the antenna device in the embodiment of the present application does not change with the sliding of the spool panel.

Preferably, the feeding portion may be disposed at a corner between the side frame 128 and the top frame 122, and the feeding portion may be disposed at a corner between the side frame 128 and the bottom frame 126.
