In step 401, a trigger operation on the switch button is detected, and step 402 or 404 is performed.

The states of the foldable device include an unfolded state and a folded state, and the foldable device may provide a switch button for instructing to switch the state of the foldable device. Therefore, when the user needs to switch the state of the foldable device, the switch button is triggered, the foldable device detects the trigger operation, and switches the state based on the trigger operation.

Since the foldable device detects the triggering operation of the switching button in different states, the target state to be switched is different, and the state switching operation performed should also be different.

In order to facilitate the distinction, the foldable device is provided with a first state switching instruction and a second state switching instruction, and the target state of the first state switching instruction is the expanded state, that is, the first state switching instruction is used to instruct the foldable device to switch to the expanded state, The target state of the second state switching instruction is the folded state, that is, the second state switching instruction is used to instruct the foldable device to switch to the folded state. By using the above two different state switching instructions, the foldable device can be switched to different states.

Therefore, when the foldable device detects the trigger operation of the switch button, it will determine the state switching instruction received by the foldable device according to the current state of the foldable device, so as to perform different state switching operations.

In the first case, when the foldable device detects the triggering operation of the switching button and determines that it is currently in the folded state, it is determined that the first state switching instruction is received.

The relative positional relationship of , and then switch the state of the foldable device.

The first direction and the second direction refer to different directions. When the first direction is a clockwise direction, the second direction is a counterclockwise direction, or, when the first direction is a counterclockwise direction, the second direction is a clockwise direction. Clockwise. Each shell rotates clockwise or counterclockwise, depending on the position of the shell in the foldable device, and it is only necessary to ensure that after synchronous rotation, the first shell, the second shell and the third shell The body is on the same plane, making the foldable device switch to the unfolded state.

Referring to Fig. 2, the first shell and the third shell at both ends of the foldable device are located on the rear side of the second shell and are in a folded state. When receiving the first state switching command, control the first shell The body rotates clockwise around the axis of rotation, and controls the third shell to rotate synchronously counterclockwise around the axis of rotation until the first shell, the second shell and the third shell are on the same plane, and the foldable device switches to Fig. 1 until the state shown.

It should be noted that step 403 only takes three casings and two rotating shafts as an example. For any three casings and corresponding rotating shafts in the foldable device, the state switching method of step 403 can be used.

In step 404, when the foldable device is currently in the unfolded state, it is determined that a second state switching instruction is received.

In the second case, when the foldable device detects the triggering operation of the switching button and determines that it is currently in the unfolded state, it is determined that the second state switching instruction is received.

In step 405, the first casing is controlled to rotate around the first rotation axis according to the second direction, and the third casing is controlled to rotate around the second rotation shaft according to the first direction synchronously, until the first casing and the third casing are both connected to the second rotation axis. The outer surface of the housing is in contact.

The foldable device in the embodiment of the present disclosure includes: a first rotating shaft, a second rotating shaft, a first casing, a second casing and a third casing as an example for description.

Whether each shell rotates clockwise or counterclockwise depends on the position of the shell in the foldable device, it is only necessary to ensure that after synchronous rotation, the first shell and the third shell are both connected with the second shell. The outer surfaces of the housings come into contact, causing the foldable device to switch to the folded state.

Referring to Figure 1, the first and third housings at both ends of the foldable device are located on the same plane as the second housing and are in an unfolded state. When receiving the second state switching command, control the first Rotate the rotation axis counterclockwise, and control the third shell to rotate synchronously clockwise around the rotation axis, until the first shell and the third shell are both located on the back side of the second shell, and the foldable device switches to the picture 2 until the state shown.

It should be noted that step 405 only takes three casings and two rotating shafts as an example, and for any three casings and corresponding rotating shafts in the foldable device, the state switching method of step 405 can be used.

It should be noted that the foldable device may further include a processing unit. The processing unit is connected to each rotating shaft and is located in a space formed by at least three housings. The methods shown in the embodiments of the present disclosure may be executed by the processing unit. By controlling the rotating shaft, the state switching of the foldable device is realized.

In the method provided by the embodiment of the present disclosure, when the foldable device receives the state switching instruction, it can switch to the target state of the state switching instruction, and the user does not need to manually rotate the casing of the foldable device to perform the state switching operation, which simplifies the state switching operation. The operation of the user is improved, the state switching efficiency is improved, the problem of damage to the foldable device due to the user's inability to control the rotation speed and force is avoided, and the life of the foldable device is prolonged.

In a possible implementation manner, since the user is accustomed to switching the state of the foldable device by applying an external force to the casing, it is extremely easy to damage the foldable device because it is difficult for the user to control the force. Therefore, when the user applies an external force, the foldable device can cooperate with the external force applied by the user to realize state switching.

This method can include but is not limited to the following two situations:

The first situation: when any one of the at least three casings rotates around the connected rotating shaft due to an external force, it is determined that a state switching command corresponding to the rotation direction of the casing is received.

The foldable device is currently in the folded state. When the user wants to switch to the unfolded state, an external force can be applied to any shell, so that the shell rotates around the connected axis due to the external force, so that the shell is adjacent to it. The angle between the shells gradually increases. Alternatively, when the foldable device is currently in the unfolded state, when the user wants to switch to the folded state, an external force can be applied to any of the casings, so that the casing is rotated around the connected shaft due to the external force, so that the casing and the The angle between adjacent shells gradually decreases.

Therefore, the foldable device can detect the rotating action of the casing, and determine the rotating direction of the casing, and the rotating direction can represent the target state to be switched to at present. The foldable device determines to receive a state switching instruction corresponding to the rotation direction of the casing, and then automatically controls at least three casings in the foldable device to rotate synchronously based on the state switching instruction until the foldable device switches to the corresponding state. .

For example, if the foldable device determines the rotation direction of the casing, and determines that the rotation according to the rotation direction will cause the angle between the casing and the adjacent casing to increase, indicating that the target state is the unfolded state, it is determined to receive Switch to the first state command. If the foldable device determines the rotation direction of the casing, and determines that the rotation according to the rotation direction will cause the angle between the casing and the adjacent casing to become smaller, indicating that the target state is the folded state, it is determined that the first Two state switching instructions.

Fig. 5 is a schematic diagram showing a direction of applying an external force according to an exemplary embodiment. The direction of the arrow in Fig. 5 is the direction in which the user applies the external force, and the external force will cause the housing to rotate counterclockwise around the rotation axis. Switch to the first state command.

In a possible implementation manner, the processing unit detects changes in the relative positional relationship of the two rotating rods on each rotating shaft, and when it is detected that the two rotating rods on any rotating shaft have an opening and closing action, and the relative positional relationship changes , indicating that the external force applied by the user causes the casing to rotate around the axis of rotation. At this time, the two rotating rods that control each axis of the foldable device open and close at the same rate. That is, when any one of the casings rotates around the connected shaft, the other casings also rotate synchronously around the connected shaft.

The second situation: when it is detected by the pressure sensor that the pressure on any one of the casings is greater than the preset threshold, it is determined that a state switching command corresponding to the pressure application direction of the casing is received.

The foldable device is currently in a folded state, and when the user wants to switch to the unfolded state, pressure can be applied to either casing, causing the casing to rotate around the connected axis due to the pressure so that the casing is adjacent to it The angle between the shells gradually increases. Alternatively, when the foldable device is currently in the unfolded state, when the user wants to switch to the folded state, pressure can be applied to either casing, so that the casing is rotated around the connected shaft due to the pressure, so that the casing and its The angle between adjacent shells gradually decreases.

The magnitude of the pressure and the direction of pressure application can reflect the user's needs. For example, when the pressure is high, it can be determined that the user wants to switch the state of the foldable device, and the pressure application direction can indicate which target state the user wants to switch to.

Therefore, the foldable device can be provided with a pressure sensor on the casing, and the pressure applied by the user can be detected by the pressure sensor. When it is detected by the pressure sensor that the pressure on any one of the casings is greater than the preset threshold, it means that the user wants to switch the state of the foldable device, and it is determined that a state switching instruction corresponding to the pressure application direction of the casing is received. Subsequently, based on the state switching instruction, at least three shells in the foldable device are automatically controlled to rotate synchronously until the foldable device switches to the corresponding state, which eliminates the need for the user to continuously exert pressure, improves the degree of intelligence, and because the foldable device switches to the corresponding state. At least three shells rotate synchronously, which ensures the uniform appearance of the foldable device and enhances the aesthetics.

For example, if the foldable device determines the pressure application direction of the casing, and determines that rotating according to the pressure application direction will cause the angle between the casing and the adjacent casing to increase, indicating that the target state is the unfolded state, then It is determined that the first state switching instruction is received. If the foldable device determines the pressure application direction of the casing, and determines that rotating according to the pressure application direction will cause the angle between the casing and the adjacent casing to become smaller, indicating that the target state is the folded state, it is determined to receive Switch to the second state command.

Wherein, the preset threshold may be determined by the amount of pressure that the user generally applies when breaking the casing, or the preset threshold may be slightly smaller than the pressure generally applied by the user when breaking the casing, or other methods may be used to set the Preset threshold.

In order to realize pressure detection, one or more housings of the foldable device are provided with pressure sensors, and the processing unit is connected to each of the provided pressure sensors, so that the pressure on the one or more housings can be detected.

Wherein, the position of the pressure sensor can be set arbitrarily, or set according to the case where pressure is often applied when the user switches the state of the foldable device. For example, pressure sensors may be provided on the edge of each housing, or on housings located on the edges of the foldable device and not on other housings. Alternatively, a pressure sensor may also be arranged in the space formed by at least three housings and below the flexible display screen.

Fig. 6 is a schematic diagram showing a pressure application direction according to an exemplary embodiment. As shown in Figure 6, the foldable device is currently in the unfolded state. When the user wants to switch to the folded state, pressure is applied on the right casing. The pressure sensor detects the pressure applied by the user and sends it to the processing unit. When the processing unit determines When the pressure is greater than the preset threshold and the pressure is applied in a downward direction, it is determined that a second state switching instruction is received.

It should be noted that the above two cases are only described by taking any one of the shells as an example to receive external force. In fact, when the user applies external force to multiple shells at the same time, the above two methods can be used for each shell. Determine the corresponding state switching instruction, and switch to the target state based on the state switching instruction.

Wherein, when the state switching instruction determined for each casing is the same, the switching is performed based on the state switching instruction. When the state switching instructions determined for different housings are different, the switching can be performed based on one of the state switching instructions, or the state switching is not performed, and the user is prompted on the flexible display screen to select the target state to be switched to.

In the method provided by the embodiment of the present disclosure, by detecting the external force exerted by the user on the casing, it is determined that a state switching instruction corresponding to the rotation direction of the casing is received, and based on the state switching instruction, at least three casings in the foldable device are automatically controlled The body rotates synchronously until the foldable device switches to the corresponding state, which no longer requires the user to continuously exert pressure, which improves the degree of intelligence, and because at least three shells rotate synchronously, the uniform appearance of the foldable device is guaranteed. , which enhances the aesthetics.

On the basis of the above-mentioned embodiment, the states of the foldable device can be further divided into three states: an unfolded state, a first folded state and a second folded state, and the first folded state and the second folded state are both folded states. The schematic diagram of the foldable device in the second folded state is shown in FIG. 7 . Referring to Figures 1, 2 and 7, the unfolded state is a state in which at least three shells are on the same plane, the first folded state is a state in which the edge shells of the at least three shells are located on the rear side of the other shells, the second The folded state is a state in which the angle formed between the edge housing and the adjacent housing in the at least three housings is a preset obtuse angle.

The edge case refers to the case that is located at the edge of the foldable device and only connected to one rotating shaft among the at least three housings of the foldable device. The state in which the edge case is located on the rear side of the other case refers to a state in which the edge case is in contact with the rear side surface of the other case after being rotated about the rotation axis. The preset obtuse angle can be the angle formed by the two shells when a general user holds the edge shell and the adjacent shells of the edge shell face the user, or set by the user, or set by the foldable device by default, which can be 135 degrees , 140 degrees, 145 degrees, or other obtuse angles that meet the requirements.

When the foldable device is in the unfolded state, the edge case can be folded until the angle between the edge case and the adjacent case is reduced to a preset obtuse angle, that is, it switches to the first folded state. When the edge shell is folded, when the angle between the edge shell and the adjacent shell is reduced to 0 degrees, it switches to the second folded state.

When the foldable device is in the first folded state, the edge case can be further folded until the angle between the edge case and the adjacent case is reduced to 0 degrees, namely switching to the second folded state. Alternatively, when the foldable device is in the first folded state, the edge housing may be unfolded until the angle between the edge housing and the adjacent housing increases to 180 degrees, ie, switching to the unfolded state.

When the foldable device is in the second folded state, the edge case can be unfolded until the angle between the edge case and the adjacent case increases to a preset obtuse angle, that is, it switches to the first folded state. Continue to unfold the edge shell, when the angle between the edge shell and the adjacent shell increases to 180 degrees, it switches to the unfolded state.

In order to facilitate the determination of the target state to be switched to each time, three switching buttons can be correspondingly set, and each switching button corresponds to a state switching instruction. The corresponding state switching instruction is then switched to the target state indicated by the state switching instruction.

Then, in the case that the first switching key is valid, when a triggering operation on the first switching key is detected, it is determined that the first state switching instruction is received. In the case of disabling the first switch button, when a trigger operation on the first switch button is detected, the trigger operation is ignored.

In step 407, when a triggering operation of the second switch button is detected, it is determined that a third state switching instruction is received, and the third state switching instruction is used to instruct the foldable device to switch to the first folding state, based on the third state The toggle instruction toggles the state of the foldable device.

Step 407 is similar to the above steps 401, 404, and 405, except that in step 407, the current state of the foldable device may be the unfolded state or the second folded state.

When the foldable device is in the unfolded state, control the at least three shells to rotate synchronously around the connected shafts, first switch to the second folded state, and then continue to control the at least three shells to rotate synchronously around the connected shafts until it switches to the second folded state. a folded state.

When the foldable device is in the unfolded state, the at least three housings are controlled to rotate synchronously around the connected shafts until they are switched to the second folding state, without being folded to the rear side surface of the edge housing and the rear side surface of the adjacent housing touch.

For example, the first casing is controlled to rotate around the first axis in the second direction, and the third casing is controlled to rotate around the second axis in the first direction, until the angle formed between the first casing and the second casing, the first The angles formed between the three shells and the second shell are all preset obtuse angles.

In another possible implementation manner, the foldable device is currently in the first folding state, and after receiving the fourth state switching instruction, it switches from the first folding state to the second folding state.

When the foldable device is in the first folded state, the at least three shells are controlled to rotate synchronously around the connected shafts until they switch to the second folded state, without being folded until the edge shells and the adjacent shells are on the same plane.

For example, the first casing is controlled to rotate around the first axis in the first direction, and the third casing is synchronously rotated around the second axis in the second direction until the angle formed between the first casing and the second casing, the first The angles formed between the three shells and the second shell are all preset obtuse angles.

It should be noted that when the foldable device is not in the second folding state, the third switch button is set to an active state, and when the foldable device is in the second folding state, the third switch button is set to a disabled state, The user is not allowed to trigger the third toggle key.

Then, in the case that the third switch button is valid, when a trigger operation on the third switch button is detected, it is determined that a fourth state switch instruction is received.
