the telescopic device 100 is switchable between an extended state and a retracted state to adjust a display area of the first display side;

wherein, in the case that the telescopic device 100 is in the extended state, the feeding point 129 is conducted with the first antenna trace to form a first antenna;

in the case that the telescopic device 100 is in the retracted state, the feeding point 129 is conducted with the second antenna trace 203 to form a second antenna, and the working frequency band of the first antenna is different from that of the second antenna.

The extended state may refer to a state in which the telescopic device 100 is fully extended, and correspondingly, the retracted state may refer to a state in which the telescopic device 100 is fully retracted. Specifically, referring to fig. 15, fig. 15 is a schematic structural diagram of the electronic device in the extended state of the telescopic device 100, where the display area of the first side is the largest. During the gradual retraction of the telescopic device 100 from the extended state, the display area of the second area gradually decreases until the telescopic device 100 is fully retracted to the retracted state as illustrated in fig. 17.

It will be appreciated that the telescopic device 100 may be moved to any telescopic position between the telescopic state and the retracted state, in addition to the extended state and the retracted state, so that the adjustment of the display area of the first side may be achieved by controlling the telescopic movement of the telescopic device 100.

When the detecting element detects that the telescopic device 100 is in the retracted state, the control circuit controls the feeding point 129 to be conducted with the second antenna wire 203 so as to form a second antenna.

Wherein, when the feeding point 129 is conducted with the first antenna trace, the feeding point 129 is disconnected with the second antenna trace 203; accordingly, in the case where the feeding point 129 is conducted with the second antenna trace 203, the feeding point 129 is disconnected from the first antenna trace. The feeding point 129 may be in communication with the first antenna trace during movement of the telescopic device 100 from the extended state to the retracted state. In addition, during the movement of the telescopic device 100 from the extended state to the retracted state, the feeding point 129 may also be disconnected from the first antenna trace, while the feeding point 129 is disconnected from the second antenna trace 203. During movement of the telescopic device 100 from the retracted state to the extended state, the feeding point 129 may be in communication with the second antenna track 203. In addition, during the movement of the telescopic device 100 from the retracted state to the extended state, the feeding point 129 may also be disconnected from the second antenna trace 203, while the feeding point 129 is disconnected from the first antenna trace.

It will be appreciated that the electronic device shown in fig. 16 is only one example of this embodiment in the first extended state, which may in fact refer to: the telescopic device 100 is located in any telescopic position between a retracted state and a second extended state.

When the telescopic device 100 is in the target extension state of the at least one third extension state, the feeding point 129 is conducted with a target sub-antenna trace, so as to form a target antenna, wherein the target sub-antenna trace is a third sub-antenna trace corresponding to the target extension state in the at least one third sub-antenna trace. And the working frequency bands of the third sub-antenna wires are different.

Accordingly, when the telescopic device 100 needs to be controlled to move from the retracted position to other positions, the movement of the conveyor belt 103 can be controlled, at this time, the conveyor belt 103 pushes the first bracket 101 through the flexible screen 300, because the second limiting groove is an arc-shaped groove, one end of the locking member 120, which contacts with the slideway, is formed with an arc-shaped surface protruding towards the slideway, so that the locking member 120 slides along the groove wall of the arc-shaped groove, and meanwhile, the locking member 120 compresses the elastic member 121, so as to be separated from the second limiting groove, so that the locking assembly is unlocked to the telescopic device 100.

In addition, in another embodiment of the present application, the locking assembly may also be composed of magnetic elements, for example, the locking assembly includes a first magnetic element, a second magnetic element and a third magnetic element, where the first magnetic element and the second magnetic element are respectively embedded at two ends of the slideway, the third magnetic element is embedded in the sliding portion, when the telescopic device 100 is in an extended state, the first magnetic element and the third magnetic element are attracted to lock the telescopic device 100, and when the telescopic device 100 is in a retracted state, the second magnetic element and the third magnetic element are attracted to lock the telescopic device 100.

It will be appreciated that the telescopic device 100 may be moved to any telescopic position between the telescopic state and the retracted state, in addition to the extended state and the retracted state, so that the adjustment of the display area of the first display side may be achieved by controlling the telescopic movement of the telescopic device 100.

Further, referring to fig. 3, in the case where the telescopic device 100 is in the retracted state, since the flexible screen 300 covers both the first display side and the second display side of the telescopic device 100, the electronic apparatus may also form a double-sided screen in this state. Thereby further improving the adjustability of the form of the flexible screen 300 and alleviating the problem that the existing display screen is not adjustable in form.

Referring to fig. 2 and 3, in the process of adjusting the shape of the flexible screen 300, the driving device drives the second end 302 of the flexible screen 300 to move in the second display side along the side towards the first end 301 of the flexible screen 300, and in this process, the first end 301 of the flexible screen 300 drives the telescopic device 100 to retract, that is, drives the first support 101 of the telescopic device 100 to move towards the second support 102, and the display area of the first display side gradually decreases, and the display area of the second display side gradually increases until the display area moves to the retracted state as described in fig. 3.

The telescoping end 118 may refer to an end that reciprocates during telescoping of the telescoping device 100, and the fixed end 119 may refer to an end that remains stationary during telescoping of the telescoping device 100. It will be appreciated that the distance between the telescoping end 118 and the fixed end 119 is constantly changing during telescoping movement of the telescoping device 100, and that the distance between the telescoping end 118 and the fixed end 119 is increasing during extension of the telescoping device 100, and the distance between the telescoping end 118 and the fixed end 119 is gradually decreasing during retraction of the telescoping device 100.

Accordingly, as shown in fig. 3, when the telescopic device 100 drives the second end 302 of the flexible screen 300 to move toward the fixed end 119, the second end 302 of the flexible screen 300 may push the telescopic end 118 to extend. Thus, the telescopic movement of the telescopic device 100 can be controlled.
