For example: the frame is partially multiplexed into a first antenna assembly ANT1 and partially multiplexed into a second antenna assembly ANT2. The first antenna assembly ANT1 and the second antenna assembly ANT2 may be in the form of an antenna based on a flexible main board, an antenna based on laser direct structuring, or an antenna form such as a microstrip antenna (Microstrip Disk Antenna, MDA). The formation manner and the arrangement position of the first antenna assembly ANT1 and other antenna assemblies in the electronic device are not limited in this application, and can be set by a person skilled in the art according to needs.

The flexible display panel has flexibility such that at least a portion of the flexible display panel may be bent into an arc shape to wind from one side of the reel mechanism 2 to the other side of the reel mechanism 2. The flexible display panel includes a main display area and an extended display area connected, the housing may include a first frame and a second frame that are telescopic, the first frame may be used to support the main display area, and the second frame may be used to support the extended display area. At least part of the expansion display area is bent into an arc shape and is arranged around the scroll mechanism 2 to be spaced from the main display area, at least part of the scroll mechanism 2 supports the bending area of the expansion display area, and the scroll mechanism 2 rotates to drive the flexible display panel to move, so that the size of the area arranged at intervals with the main display area in the expansion display area is changed.

The flexible circuit board 1 (Flexible Printed Circuit, FPC) is a circuit board which can be freely bent and folded. The flexible circuit board 1 further comprises a substrate, a conductive circuit 14 and a control module 15, and the connection terminal 11, the conductive circuit 14, the control module 15 and the first feeding point 12, and the aforementioned control circuits for controlling the functional units may be embedded and attached on the substrate. The connection terminal 11 may be electrically connected to the control module 15 through the conductive line 14, and the first feeding point 12 is electrically connected to the first antenna assembly ANT1, so that when the connection terminal 11 is connected to the first feeding point 12, the control module 15, the conductive line 14, the connection terminal 11, the first feeding point 12 and the first antenna assembly ANT1 are sequentially electrically connected, and the control module 15 may control the first feeding point 12 to input an excitation current to the first antenna assembly ANT1 to excite the first antenna assembly ANT1 to generate resonance, and radiate radio frequency signals.

Illustratively, as shown in fig. 1, in the unfolded state, the flexible circuit board 1 is unfolded horizontally, the connection terminal 11 is separated from the first feeding point 12, and can communicate with the outside through other antenna components, such as the second antenna component ANT2. As shown in fig. 2, in the case where the flexible circuit board 1 is in the folded state, the flexible circuit board 1 is bent along the bending axis L, and a portion of the flexible circuit board 1 is bent from one side of the reel mechanism 2 to the other side of the reel mechanism 2 around the reel mechanism 2 so that the connection terminal 11 is brought close to and connected to the first feeding point 12, and the electronic apparatus can communicate with the outside through the first antenna assembly ANT 1. The reel mechanism 2 may have a driving member, and the reel mechanism 2 is rotated by the driving member, so that the flexible circuit board 1 may be driven to move around the reel mechanism 2.

The flexible circuit board 1 moves around the reel mechanism 2, so that the first feeding point 12 can be connected with or separated from the connection terminal 11, i.e. the distance between the first antenna assembly ANT1 and the connection terminal 11 can be shortened, or the distance between the first antenna assembly ANT1 and the connection terminal 11 can be shortened. When it is necessary to switch to the first antenna assembly ANT1 for communication, the flexible circuit board 1 may be moved around the reel mechanism 2, so that the connection terminal 11 is connected to the first feeding point 12, the control module 15 is connected to the first antenna assembly ANT1, and the control module 15 may control the first feeding point 12 to input an excitation current to the first antenna assembly ANT 1. When it is necessary to switch from the first antenna assembly ANT1 to use the other antenna assembly for communication, the connection terminal 11 may be separated from the first feeding point 12 by moving the flexible circuit board 1 around the reel mechanism 2, and the control module 15 may control the input of the excitation current to the other antenna assembly. Since the first antenna assembly ANT1 may be connected to or disconnected from the control module 15 through the connection terminal 11 and the first feeding point 12, the connection terminal 11 may be disposed close to the control module 15, and the path length of the conductive line 14 connected between the connection terminal 11 and the control module 15 may be reduced, thereby reducing the trace length between the first antenna assembly ANT1 and the control module 15 and reducing the insertion loss.

In the electronic device provided by the application, by providing the first feeding point 12 for feeding connection with the first antenna assembly ANT1, the connection terminal 11 can be connected with or separated from the first feeding point 12 along with the movement of the flexible circuit board 1 around the reel mechanism 2, so that a user can communicate with the first antenna assembly ANT1 and the flexible circuit board 1 as required, and the electronic device can communicate with the outside through the first antenna assembly ANT 1; the flexible circuit board 1 and the flexible display panel can move around the reel mechanism 2 together so that the connecting terminal 11 is connected with the first feeding point 12, thereby reducing the wiring length of the first antenna assembly ANT1 connected to the flexible circuit board 1, reducing the insertion loss and improving the communication quality of the electronic equipment.

In some embodiments, the flexible circuit board 1 includes an unfolded state and a folded state, and the connection terminal 11 is separated from the first feeding point 12 in the case where the flexible circuit board 1 is in the unfolded state; when the flexible display panel is contracted around the reel mechanism 2 and the flexible circuit board 1 is switched from the unfolded state to the folded state, at least a part of the area of the flexible circuit board 1 is bent, and the connection terminal 11 is connected to the first feeding point 12.

The flexible display panel is stretched around the reel mechanism 2, and the flexible circuit board 1 is switched from the folded state to the unfolded state. The flexible display panel stretches out and draws back, so that the flexible circuit board 1 linked with the flexible display panel is switched between an unfolding state and a folding state, namely, the state of the flexible circuit board 1 can change along with the stretching out and drawing back of the flexible display panel.

Referring to fig. 3, 4 and 5, in some embodiments, the number of the first antenna assemblies ANT1 and the first feeding points 12 is plural, the first antenna assemblies ANT1 are connected to the first feeding points 12 in a one-to-one correspondence manner, and the first feeding points 12 are disposed at intervals along the extending and retracting direction of the flexible display panel when the flexible circuit board 1 is in the unfolded state; the flexible circuit board 1 is moved around the reel mechanism 2 to switch the connection terminals 11 to be connected with different first feeding points 12.

The first direction X is a telescoping direction of the flexible display panel. One end of the flexible display panel can be fixed relative to the shell, the other end along the first direction X can be arranged around the reel mechanism 2, the driving piece drives the reel mechanism 2 to move along the first direction X, the reel mechanism 2 drives one end of the flexible display panel to stretch and retract along the first direction X, and one end of the flexible circuit board 1 stretches and contracts along the first direction X. One end of the flexible circuit board 1 is moved to a different position so that the connection terminal 11 can be connected with a different first feeding point 12.

In the embodiment provided in the present application, by providing the flexible circuit board 1 to move around the reel mechanism 2 so that the same connection terminal 11 can be connected with different first feeding points 12, excitation current can be input to different first antenna assemblies ANT1 through the first feeding points 12 in the case where the flexible display panel has different display areas.

In some embodiments, the first antenna assembly ANT1 includes a first sub-antenna ANT11 and a second sub-antenna ANT12 disposed at intervals along a second direction Y, a plurality of the first sub-antennas ANT11 are disposed at intervals along a telescopic direction of the flexible display panel, a plurality of the second sub-antennas ANT12 are disposed at intervals along a telescopic direction of the flexible display panel, the second direction Y is disposed to intersect the telescopic direction X of the flexible display panel,

the plurality of connection terminals 11 includes a first connection terminal 111 and a second connection terminal 112, and the flexible circuit board 1 moves around the reel mechanism to switch the first connection terminal 111 to be connected with a different first sub-antenna ANT11 and to switch the second connection terminal 112 to be connected with a different second sub-antenna ANT12.

The number of first feeding points 12 for feeding connection with one first antenna assembly ANT1 may be 2, 3, 4, etc. The n first feeding points 12 may be arranged in groups in a preset distribution rule for connection with the first sub-antenna ANT11 or one second sub-antenna ANT12 of the first antenna assembly ANT 1. The first feeding points 12 for feeding connection with different first antenna assemblies ANT1 may be distributed in groups according to the same distribution rule, so that when the flexible circuit board 1 moves to the first position around the reel mechanism 2, the plurality of connection terminals 11 may be connected in one-to-one correspondence with the n first feeding points 12 corresponding to the first antenna assemblies ANT1 located at the first position. When the flexible circuit board 1 moves to the second position around the reel mechanism 2, the plurality of connection terminals 11 may be connected in one-to-one correspondence with the n first feeding points 12 corresponding to the first antenna assembly ANT1 located at the second position. The second direction may be the extending direction Y of the reel mechanism 2, thereby reducing the difficulty of aligning the plurality of connection terminals with each first feeding point 12 in one repeating unit 16.

For example: the two first feeding points 12 are arranged in groups along the second direction. In the embodiment shown in fig. 4, when the reel mechanism 2 drives the flexible circuit board 1 to extend and retract to the first position along the first direction X, the two connection terminals 11 are respectively connected with the two first feeding points 12 located at the first position in a one-to-one correspondence manner so as to communicate the first sub-antenna ANT11 and the second sub-antenna ANT12.

One of the first antenna assemblies ANT1 is provided to include a first sub-antenna ANT11 and a second sub-antenna ANT12 which are disposed at intervals along the second direction Y, thereby increasing the distribution area of the first antenna assembly ANT1 and providing more antenna feeding schemes.

When the flexible circuit board 1 is bent, the substrate, the connection terminal 11, the conductive line 14, the control module 15 and the first feeding point 12 may be bent as needed. The connection terminal 11 is electrically connected to the control module 15 through the conductive line 14, and the first feeding point 12 is electrically connected to the first antenna assembly ANT1, so that when the connection terminal 11 is connected to the first feeding point 12, the control module 15, the conductive line 14, the connection terminal 11, the first feeding point 12 and the first antenna assembly ANT1 are sequentially electrically connected, and the control module 15 can control the first feeding point 12 to input an excitation current to the first antenna assembly ANT1 so as to excite the first antenna assembly ANT1 to generate resonance and radiate radio frequency signals.

In the case that the rf signals are received through the plurality of sub-antennas, respectively, the control module 15 may determine one sub-antenna as a target antenna according to the signal strength of the rf signals, and input an excitation current to the target antenna. The control module 15 can compare the signal intensity of each radio frequency signal, set the sub-antenna corresponding to the maximum signal intensity as a target antenna, and establish communication with external equipment through the target antenna, so as to improve the stability of the communication of the electronic equipment.

Any one of the connection terminals 11 is controlled to be turned on or off by the radio frequency switch, thereby controlling the first feeding point 12 connected to the connection terminal 11 to input the excitation current to the corresponding first antenna assembly ANT 1. By providing the first antenna assembly ANT1 and the second antenna assembly ANT2 to share one control module 15, the number of control modules 15 is reduced.

In the case that the rf signals are received through the plurality of sub-antennas, respectively, the control module 15 may determine one sub-antenna as a target antenna according to the signal strength of the rf signals, and input an excitation current to the target antenna.

In case the flexible circuit board 1 is in the unfolded state S1 < S2, i.e. the second feeding point 13 is closer to the control module 15 and the first feeding point 12 is further from the control module 15. The signals transmitted by the tracks provided between the first feeding point 12 and the control module 15 have a more pronounced insertion loss than the signals transmitted by the tracks provided between the second feeding point 13 and the control module 15.

The main display area may not move with the reel mechanism 2 so that the corresponding first region 171, and the connection terminal 11, the control module 15, and the second feeding point 13 disposed at the first region 171 may be prevented from being bent.
