The suction member 30 of the present application is a member that can achieve an increase in suction force between the first sub-screen 10 and the second sub-screen 20. For example, the adsorption component 30 may be magnetic blocks 323 arranged in both the first sub-panel 10 and the second sub-panel 20, and when the drop detection component 40 does not detect that the foldable panel module 100 drops, a magnetic isolation component is arranged between the magnetic blocks 323 arranged on the first sub-panel 10 and the second sub-panel 20, and the existence of the magnetic isolation component blocks the adsorption force between the magnetic blocks 323; the falling detection assembly 40 detects the condition that the folding screen module 100 falls, and the magnetism isolating piece shifts for inter attraction between the magnetic blocks 323, so as to increase the adsorption force between the first sub-screen 10 and the second sub-screen 20, so that the first sub-screen 10 and the second sub-screen 20 are adsorbed more closely, and the first sub-screen 10 and the second sub-screen 20 are protected. Alternatively, for example, the adsorption member 30 may be a magnetic induction coil provided in both the first sub-panel 10 and the second sub-panel 20, and when the drop detecting member 40 does not detect that the folding panel module 100 has dropped, the magnetic induction coil provided in the first sub-panel 10 and the second sub-panel 20 is not energized and does not generate a magnetic field; the condition that the folding screen module 100 falls is detected to the detection subassembly 40 that falls, the magnetic induction coil that will be on first sub-screen 10 and the sub-screen 20 of second circular telegram, and the magnetic induction coil that is on first sub-screen 10 and the sub-screen 20 of second flows through different electric currents, at this moment, just can produce the magnetic field of equidirectional in the magnetic induction coil that corresponds, attract each other, thereby increase the adsorption affinity between first sub-screen 10 and the sub-screen 20 of second, make first sub-screen 10 and the sub-screen 20 of second adsorb inseparabler, protect first sub-screen 10 and the sub-screen 20 of second.

The drop detection assembly 40 of the present application may be any assembly that can detect whether the folding screen module 100 is in a dropped state. For example, the fall detection assembly 40 may be a posture sensor, which may include a gravity sensor. Gravity sensors work according to the piezoelectric effect principle. The piezoelectric effect means that an external force applied to the crystal by a heteropolar crystal without a center of symmetry will change the polarization state of the crystal and create an electric field inside the crystal in addition to the deformation of the crystal. This phenomenon of dielectric polarization due to mechanical forces is called "direct piezoelectric effect". Gravity sensors utilize crystal deformation caused by internal acceleration. Since such deformation generates a voltage, the acceleration can be converted into a voltage output as long as the relationship between the generated voltage and the applied acceleration is calculated.

Under the condition that the falling detection component 40 does not detect that the folding screen module 100 falls, the adsorption component 30 can realize a target function, wherein when the adsorption component 30 is a magnetic induction coil, the current of the magnetic induction coil disappears, and the corresponding magnetic Field disappears, at this time, the target function is a charging function, and may also be an nfc (near Field communication) function, and meanwhile, the first sub-screen 10 and the second sub-screen 20 are also easier to unfold.

In the embodiment of the application, the folding screen module 100 is through setting up the adsorption component 30, falling detection component 40 and controller 50, and the controller 50 is connected with the adsorption component 30 and falls detection component 40 electricity, and under the condition that the falling detection component 40 detected that the folding screen module 100 fell, the controller 50 received the electrical signal of falling detection component 40 and transmitted the execution command to the adsorption component 30, and the adsorption component 30 is in different operating conditions under the control of the controller 50. So, first sub-screen 10 and the sub-screen 20 of second in the folding screen module 100 are in fold condition, and fall under the condition that the detection component 40 detected folding screen module 100 and dropped, controller 50 control adsorption component 30, in order to increase the adsorption affinity between first sub-screen 10 and the sub-screen 20 of second, make first sub-screen 10 adsorb inseparabler with the sub-screen 20 of second, when folding screen module 100 receives the impact force because of falling, can certain degree avoid or reduce first sub-screen 10 and the expansion of the sub-screen 20 of second, prevent first sub-screen 10 and the damage of the sub-screen 20 of second.
