In the embodiment of the present application, the driving module is connected with the first gear 9 and/or the second gear 10 through a connecting device 11.

For example, the driving module is connected with the first gear 9, the driving module can drive the first gear 9 to rotate, and the rotation of the first gear 9 can also drive the second gear 10 to rotate in the opposite direction, so as to drive the first connecting shaft 12 and the second connecting shaft 13 to rotate; under the condition that the bendable region 6 is flat, the first gear 9 and the second gear 10 respectively rotate in opposite directions to drive the bendable region 6 to be folded, and then the middle frame 1 and the foldable display screen 2 are in a folded state; on the same principle, when the bendable region 6 is in the folded state, the first gear 9 and the second gear 10 respectively rotate reversely, the bendable region 6 can be driven to be unfolded, and then the middle frame 1 and the foldable display screen 2 are in the unfolded state.

It can be understood that the driving module can also be connected with the second gear 10 through the connecting device 11, and drives the second gear 10 to rotate to realize bending and flattening of the bendable region 6; or, the driving module is connected with the first gear 9 and the second gear 10, and can simultaneously drive the first gear 9 and the second gear 10 to rotate in opposite directions, so as to realize bending and flattening of the bendable region 6, and the specific principle is similar to the above-mentioned driving of the first gear 9, and is not repeated here.

Referring to fig. 1 to 4, the driving module is connected to the transmission assembly 5 through a connecting device. Alternatively, the connecting device may be a connecting rod or a connecting rope, and the connecting device is specifically described as the connecting rod in the embodiment of the present application.

Optionally, the driving module includes a first extensible member 3, the connecting device includes a first connecting rod 11, one end of the first connecting rod 11 is connected to the first gear 9, the other end of the first connecting rod 11 is connected to the first extensible member 3, the first extensible member 3 is connected to the processor, the first extensible member 3 can achieve telescopic motion, the telescopic motion of the first extensible member 3 can also drive the first connecting rod 11 to move, and then the first connecting rod 11 can drive the first gear 9 and the second gear 10 to rotate. Wherein, the treater can control first extensible member 3 and realize stretching out and drawing back, and the flexible of first extensible member 3 can produce thrust or pulling force to head rod 11, and then in order to drive first gear 9 and rotate to the first direction or to the second direction.

For example, the first connecting rod 11 is connected to the first gear 9, when the middle frame 1 and the foldable display screen 2 are in the unfolded state, if the processor controls the first extensible member 3 to perform an extension motion, that is, the length of the first extensible member 3 is increased, the first extensible member 3 generates a thrust to the first connecting rod 11, the thrust of the first connecting rod 11 can push the first gear 9 to rotate clockwise, and further drive the second gear 10 engaged with the first gear 9 to rotate counterclockwise, because the positions of the first gear 9 and the second gear 10 relative to the bendable region 6 are not changed, the rotation of the first gear 9 and the second gear 10 can also drive the bendable region 6 to bend, and further drive the middle frame 1 and the foldable display screen 2 to be folded. Based on similar principle, shorten the motion when first extensible member 3 of treater control, the length that also is first extensible member 3 reduces, then first extensible member 3 produces the pulling force to first connecting piece, the pulling force of first connecting piece can drive first gear 9 and rotate to anticlockwise, and then drive second gear 10 and rotate to clockwise, the antiport of first gear 9 and second gear 10 just also can drive 6 flat exhibitions of bendable region, and then switch to the expansion state with driving center 1 and collapsible display screen 2. Thus, the folding and unfolding of the middle frame 1 and the foldable display screen 2 are realized by the telescopic movement of the first telescopic member 3 and further by driving the two gears to rotate in different directions.

Optionally, the driving module includes a first telescopic rod 16 and a first telescopic cavity 15, or the first telescopic member 3 includes a first telescopic rod 16 and a first telescopic cavity 15, at least a portion of the first telescopic rod 16 is accommodated in the first telescopic cavity 15, and one end of the first telescopic cavity 15 is connected to the first connecting rod 11.

It can be understood that, in the structure of the driving module, the first telescopic member 3 performs an extension movement, that is, the length of the first telescopic rod in the first telescopic cavity is reduced, and the length of the whole first telescopic member is increased; first extensible member 3 shortens the motion, and the length that first telescopic link is in first flexible intracavity increases promptly, and whole first extensible member length reduces.

In an alternative embodiment, one end of the first telescopic rod 16 is fixed on a first side of the middle frame 1 and is connected with the processor, for example, the processor is connected with the wire 7, the other end of the first telescopic rod 16 is accommodated in the first telescopic cavity 15, and one end of the first telescopic cavity 15 far away from the first telescopic rod 16 is connected with the first connecting rod 11; the first telescopic rod 16 can drive the first telescopic cavity 15 to move relative to the first telescopic rod 16, and under the condition that the first telescopic cavity 15 performs telescopic movement relative to the first telescopic rod 16, the first telescopic cavity 15 drives the first gear 9 to rotate. That is, the first telescoping rod 16 is stationary, the first telescoping rod 16 is connected to the disposer, and the first telescoping rod 16 can be powered to extend or retract the first telescoping lumen 15 relative to the first telescoping rod 16. For example, the first telescopic cavity 15 may be a magnetic member, and the first telescopic rod 16 generates an electromagnetic field under the condition of conducting electricity, so as to generate a repulsive force or an attractive force on the first telescopic cavity 15 to push the first telescopic cavity 15 to perform telescopic motion relative to the first telescopic rod 16.

Further, the first gear 9 has a first angle with the length direction of the first telescopic cavity 15, or the center of the first gear 9 is deviated from the length direction of the first telescopic cavity 15; the length direction of the first connecting rod 11 is also at an angle to the length direction of the first bellows 15. Therefore, when the first telescopic cavity 15 moves, the pushing force or the pulling force can be better generated on the first connecting rod 11, and the bendable area 6 is ensured to be bent or unfolded.

It should be noted that the first telescopic member 3 further includes a limiting member, the limiting member may be disposed on an inner wall of the first telescopic cavity or an outer wall of the first telescopic rod, and the setting of the limiting member can limit a maximum extension length of the first telescopic cavity relative to the first telescopic rod, so as to avoid separation of the first telescopic cavity from the first telescopic rod. The first telescopic member 16 is fixedly connected with the middle frame 1 through a positioning member 21 to ensure the stability of the first telescopic member 16 on the middle frame 1.

Wherein, first deformation piece 22 can be the deformation that takes place periodicity under the circumstances of circular telegram, because first deformation piece 22 and first flexible chamber 15 butt, can produce periodic frictional force between first deformation piece 22 and the first flexible chamber 15 inner wall, and then promote the motion of first flexible chamber 15.

The electronic device further comprises a power device, wherein the power device is electrically connected with the first telescopic piece 22 under the condition that the first deformation block 22 is made of electrostrictive materials, and the power device is used for driving the first deformation block 22 to deform. For example, the power device may be a processor in an electronic device, or a power supply module, etc. to supply power to the first deformation block 22.

For example, the material of the first deformation block 22 may be electrostrictive material, such as piezoelectric ceramic. Referring to fig. 5, the first deformation block 22 further includes a positive conductive plate 25 and a negative conductive plate 26, the positive conductive plate 25 is connected to the processor through a positive lead 23, and the negative conductive plate 26 is connected to the processor through a negative lead 24. Referring to fig. 6, when the positive conductive plate 25 is powered on, the first deformation block 22 deforms in the second direction, so as to increase the friction between the first deformation block and the inner wall of the first telescopic cavity 15, so as to push the first telescopic cavity 15 to move in the first direction (the right direction shown in fig. 3), and then the first telescopic cavity 15 generates a thrust force on the first connecting rod 11, so as to drive the first gear 9 and the second gear 10 to move, so as to fold the middle frame 1 and the foldable display screen 2. And under the condition that the negative pole conducting plate 26 is electrified, the first deformation block 22 deforms towards the first direction to push the first telescopic cavity 15 to move towards the second direction, and further generates a pulling force on the first connecting rod 11 to drive the first gear 9 and the second gear 10 to move, so that the expansion of the middle frame 1 and the foldable display screen 2 is realized.

In the embodiment of the application, through the electrification to first deformation block 22, can make first deformation block 22 take place deformation, just also can drive first flexible chamber 15 and realize concertina movement to realize that center 1 and collapsible display screen 2 switch between folding and expansion state. Therefore, the electric control on the middle frame 1 and the foldable display screen 2 is realized, the folding or unfolding is not required to be realized through manual folding operation by a user, and further the damage of electronic equipment hardware caused by the manual folding operation can be avoided. It should be noted that the first deformation block 22 may also be made of other materials capable of generating deformation, such as a magnetostrictive material, a photo-induced telescopic material, and the like, and the specific deformation principle may refer to the related art, which is not described in detail in this embodiment.

Therefore, the user does not need to manually fold or unfold the electronic equipment, and the electronic equipment is more convenient to use.

By the same principle, the first telescopic member 3 and the second telescopic member 4 can drive the middle frame 1 and the foldable display screen 2 to the unfolded state. Like this, the treater can produce drive power to first gear 9 and second gear 10 better through controlling first extensible member 3 and the simultaneous movement of second extensible member 4, realizes the accurate control to center 1 and collapsible display screen 2.

It should be noted that, an included angle exists between the first connecting rod 11 and the second connecting rod 14, and when the first connecting rod 11 and the second connecting rod 14 move relatively or away from each other, a component force can be generated at an included angle between the extending directions of the two connecting rods by the included angle, so as to promote the two gears to move in a relative meshing manner, so as to ensure that the bendable region 6 is driven to bend or flatten.

Alternatively, the material of the second deformation block 27 may be an electrostrictive material, such as piezoelectric ceramic. The second deformation block 27 can be arranged in the same way as the first deformation block 22, and realizes deformation based on the same principle, so as to push the second telescopic cavity 17 to move, so as to realize folding and unfolding of the middle frame 1 and the foldable display screen 2.
