Optionally, referring to fig. 2, the active folding structure 31 includes:

the electrode structure includes a first electrode pattern layer 311, a second electrode pattern layer 312, and a dielectric layer 313, wherein the first electrode pattern layer 311 is disposed on an upper surface of the dielectric layer 313, and the second electrode pattern layer 312 is disposed on a lower surface of the dielectric layer.

Alternatively, the dielectric layer 313 in the embodiment of the present invention may be a Dielectric Elastomer (DE). In particular, DE is a novel electrostrictive material; DE is generally an Electroactive Polymer (Electroactive Polymer) that is characterized by the ability to convert electrical energy into mechanical energy.

Still further, referring to fig. 4, the folding screen terminal device further includes: a detection device 4;

in the process that the active folding structure 31 outputs a first moment, if the folding angle of the first screen unit 1 and the second screen unit 2 reaches a first target angle, the active folding structure 31 stops outputting the first moment;

in the process that the active folding structure 31 outputs the second moment, if the folding angle of the first screen unit 1 and the second screen unit 2 reaches the second target angle, the active folding structure 31 stops outputting the second moment.

For example, the detection device 4 in the embodiment of the present invention may be a piezoelectric sensor.

Since the folding screen terminal device provided in the above embodiment further includes the folding angle detection device 4 capable of detecting the first screen unit 1 and the second screen unit 2, the terminal device can acquire the folding state of the first screen unit and the second screen unit through the detection device 4.

The working principle of the folding screen terminal device provided by the above embodiment is described below by taking the active folding structure as the active folding structure shown in fig. 2 and the passive folding device as the hinge shown in fig. 3 as an example.

In a first aspect, in a case where a user wants to fold a first screen unit and a second screen unit (rotate the first screen unit in a counterclockwise direction with respect to the second screen unit), the user inputs a first target input to a folding screen terminal device, and the terminal device controls voltages applied to a first electrode pattern layer and a second electrode pattern layer in response to the first target input by the user, so that the active folding structure outputs the first moment. At this time, because the first moment is smaller than the damping of the hinge, the first screen unit and the second screen unit do not produce folding action, the folding state of the folding screen terminal equipment does not change actively, but the damping of the folding first screen unit and the second screen unit is reduced due to the interaction of the first moment and the damping of the hinge; after the active folding structure outputs the first moment, the user only needs to apply a small acting force to enable the first screen unit and the second screen unit to generate the folding action, so that the acting force applied when the user folds the first screen unit and the second screen unit can be firstly reduced by the embodiment, and components in the non-bending area of the folding screen terminal device are protected.

In a second aspect, in a case where a user wants to unfold the first screen unit and the second screen unit (rotate the first screen unit relative to the second screen unit in a clockwise direction), the user inputs a second target input to the folding screen terminal device, and the terminal device controls voltages applied to the first electrode pattern layer and the second electrode pattern layer in response to the second target input by the user, so that the active folding structure outputs the second moment. At this time, the second moment is smaller than the damping of the hinge, so that the first screen unit and the second screen unit do not generate folding action, the folding state of the folding screen terminal equipment does not actively change, but the damping of the folding first screen unit and the second screen unit is reduced due to the interaction of the second moment and the damping of the hinge; after the active folding structure outputs the second moment, the user only needs to apply a smaller acting force to enable the first screen unit and the second screen unit to generate unfolding actions, so that the acting force applied when the user unfolds the first screen unit and the second screen unit can be reduced, and components in the non-bending area of the folding screen terminal device are protected.

In a third aspect, in a case where the user wants to maintain the folded states of the first screen unit and the second screen unit, the user does not input either the first target input or the second target output; and the folding screen terminal equipment controls the voltage applied to the first electrode pattern layer and the second click pattern layer, so that the active folding structure does not output torque. At this time, the resistance to be overcome when the first screen unit and the second screen unit are folded is large, and the resistance to be overcome when the first screen unit and the second screen unit are unfolded is also large, so the above embodiment can also prevent the folded states of the first screen unit and the second screen unit from being changed by an artificial external force to some extent.

The embodiment of the invention also provides a control method of the folding screen terminal device, and the control method of the folding screen terminal device is applied to the folding screen terminal device provided by any one of the embodiments. Specifically, referring to fig. 5, the control method of the folding screen terminal device includes the following steps 101 to 104.

Step 101, receiving a first input of a user.

Specifically, in the embodiment of the present application, the first input may be an input to the fingerprint identification module, an input to a physical key, an input to the voice receiving module, or an input to the touch receiving module.

The input to the touch receiving module may specifically be any one of a touch click input, a touch slide input, a double-click input, a single-click gesture, a slide gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture, and a double-click gesture.

Step 102, determining whether the first input matches a first target input or a second target input.

In particular, the first target input and the second target input may be preset by a user. For example: the user may set the first target input as the first fingerprint information and the second target input as the second fingerprint information. For another example: the first target input is set as first key information, and the second target input is set as second key information. For another example: the first target input is set as a first touch input and the second target input is set as fingerprint information.

Optionally, the first input is fingerprint information input by a user.

The step 102 of determining whether the first input matches the first target input or the second target input may specifically be: determining whether the fingerprint information input by the user is first fingerprint information or second fingerprint information.

That is, the user sets the first target input as the first fingerprint information and the second target input as the second fingerprint information, and when the fingerprint information input by the user is received, the fingerprint information input by the user is matched with the first fingerprint information and the second fingerprint information, respectively, thereby determining whether the user inputs the first target input or the second target input.

Optionally, the first input is key information input by a user.

The step 102 of determining whether the first input matches the first target input or the second target input may specifically be: and determining whether the key information input by the user is the first key information or the second key information.

That is, the user sets the first target input as the first key information and the second target input as the second key information, and when the key information input by the user is received, the key information input by the user is respectively matched with the first key information and the second key information, thereby determining whether the user inputs the first target input or the second target input.

In the step 102, if the first input matches the first target input, the following step 103 is executed; if the first input matches the second target input, the following step 104 is performed.

And 103, controlling the active folding structure to output the first moment.

And 104, controlling the active folding structure to output the second moment.

In an embodiment, the folding screen terminal device may control the active folding structure to output a first moment that causes the first screen unit to rotate in the first direction relative to the second screen unit or causes the first screen unit to generate a first moment with a rotation trend in the first direction relative to the second screen unit under the condition of receiving a first target input by a user, so that when the user needs to rotate the first screen unit in the first direction relative to the second screen unit, the active folding structure may be controlled to output the first moment, so as to counteract damping of a part of the passive folding structure, further reduce acting force that the user needs to apply to the first screen unit and the second screen unit, and avoid damaging components in an unbendable region of the folding screen terminal device; and because the folding screen terminal device can control the active folding structure to output a second moment which enables the first screen unit to rotate along the second direction relative to the second screen unit or enables the first screen unit to generate a rotation trend in the second direction relative to the second screen unit under the condition of receiving a second target input by a user, when the user needs to enable the first screen unit to rotate along the second direction relative to the second screen unit, the active folding structure can be controlled to output the second moment, so that damping of a part of the passive folding structure is offset, acting force which needs to be applied to the first screen unit and the second screen unit by the user is further reduced, and damage to components in an unbendable area of the folding screen terminal device is avoided. That is, the above-described embodiments can protect the device of the non-bendable region of the folding screen terminal apparatus during folding or unfolding of the first screen unit and the second screen unit.

Optionally, the method for controlling a folding screen terminal device provided in the foregoing embodiment further includes:

in the above embodiment, controlling the active folding structure to output the first torque when the first input matches the first target input includes:

and under the condition that the first input is matched with the first target input, controlling the active folding structure to output the first moment for a first preset time length.

In the above embodiment, the controlling the active folding structure to output the second moment when the first input matches the second target input includes:

and under the condition that the first input is matched with the second target input, controlling the active folding structure to output the second moment for a second preset time.

Specifically, the above embodiment may be implemented by a timer. That is, when the first input is matched with the first target input, starting a timer with a first preset duration, and if the timer is overtime, controlling the active folding structure to stop outputting the first moment; and under the condition that the first input is matched with the second target input, starting a timer with a second preset time length, and if the timer is overtime, controlling the active folding structure to stop outputting the second moment.

The above embodiment may control the active folding structure to stop outputting the first moment or the second moment after the active folding structure outputs the first moment or the second moment, so as to prevent the folding states of the first screen unit and the second screen unit from being changed by an external force.

in the process of controlling the active folding structure to output the first moment, if an intersection angle between the first screen unit and the second screen unit reaches a first target angle, controlling the active folding structure to stop outputting the first moment;

in the process of controlling the active folding structure to output the second moment, if the intersection angle between the first screen unit and the second screen unit reaches a second target angle, controlling the active folding structure to stop outputting the second moment.

Wherein the first target angle and the second target angle may be set according to a folding limit angle and an unfolding limit angle of the first screen unit and the second screen unit. For example: the maximum folding angle of the first screen unit and the second screen unit is 180 °, and the maximum unfolding angle is 0 °, the first target angle may be set to 180 °, and the second target angle may be set to 0 °.

Since the above embodiment can control the active folding structure to stop outputting the first moment if the active folding structure is controlled to output the first moment and the folding angles of the first screen unit and the second screen unit reach the first target angle, the above embodiment can avoid the first screen unit and the second screen unit from being damaged due to being folded excessively; in addition, since the above embodiment can also control the active folding structure to stop outputting the second moment when the active folding structure is controlled to output the second moment and the folding angle of the first screen unit and the second screen unit reaches the second target angle, the above embodiment can avoid the first screen unit and the second screen unit from being excessively unfolded and damaged.

a receiving unit 61 for receiving a first input of a user;

The folding screen terminal device provided by the embodiment of the invention comprises: the device comprises a first screen unit, a second screen unit, and an active folding structure and a passive folding structure which act on the first screen unit and the second screen unit; first, since the active folding structure may output a first moment that causes the first screen unit to rotate in a first direction with respect to the second screen unit or causes the first screen unit to generate a rotation tendency in the first direction with respect to the second screen unit, the passive folding structure may output a third moment in a case where the first screen unit rotates in the first direction with respect to the second screen unit or the first screen unit has a rotation tendency in the first direction with respect to the second screen unit, and the first moment is opposite in direction to the third moment, the first moment being less than or equal to the third moment, the control unit may control the active folding structure to output the first moment when the receiving unit receives a first target input of a user, therefore, damping of a part of passive folding structures is counteracted, acting force required to be applied to the first screen unit and the second screen unit by a user is reduced, and components in the non-bendable region of the folding screen terminal device are prevented from being damaged; secondly, since the active folding structure can output a second moment that causes the first screen unit to rotate in a second direction relative to the second screen unit or causes the first screen unit to generate a rotation trend in the second direction relative to the second screen unit, the passive folding structure can output a fourth moment in a case that the first screen unit rotates in the second direction relative to the second screen unit or the first screen unit has a rotation trend in the second direction relative to the second screen unit, and the second moment is opposite to the fourth moment in direction, the second moment being less than or equal to the fourth moment, the control unit can control the active folding structure to output the second moment when the receiving unit receives a second target input of the user, therefore, damping of a part of passive folding structures is counteracted, acting force required to be applied to the first screen unit and the second screen unit by a user is reduced, and components in the non-bendable region of the folding screen terminal device are prevented from being damaged; furthermore, since the passive folding structure may output a third moment in a case where the first screen unit rotates in the first direction with respect to the second screen unit, or the first screen unit has a tendency to rotate in the first direction with respect to the second screen unit, and output a fourth moment in a case where the first screen unit rotates in the second direction with respect to the second screen unit, or the first screen unit has a tendency to rotate in the second direction with respect to the second screen unit, that is, the passive folding structure may provide damping during the relative rotation of the first screen unit and the third screen, it may control the folding structure not to output an acting force in a case where the receiving unit does not receive both the first target input and the second target input actively, therefore, the folded states of the first screen unit and the second screen unit are kept through the damping of the passive folding structure, and the folded states of the first screen unit and the second screen unit are prevented from being changed by an artificial external force to a certain extent. That is, the embodiment of the present invention can not only protect the components in the unbendable region, but also prevent the folding state from changing due to an external force, so that the embodiment of the present invention can solve the problem that the folding screen terminal device in the prior art cannot protect the components in the unbendable region and prevent the folding state from changing due to the external force.
