DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0022] Referring to Figure 1 , one of the schematic diagrams of an electronic device provided by the embodiments of the present application is shown; referring to Figure 2 , another schematic diagram of an electronic device provided by the embodiments of the present application is shown; referring to Figure 3 , a third schematic diagram of an electronic device provided by the embodiments of the present application is shown; referring to Figure 4 , a fourth schematic diagram of an electronic device provided by the embodiments of the present application is shown; referring to Figure 5 , a schematic diagram of contact between a first detection piece and a second detection piece provided by the embodiments of the present application is shown; referring to Figure 6 , a schematic diagram of a circuit of an electronic device provided by the embodiments of the present application is shown 。 As Figures 1 to 6 shown, the electronic device includes a first housing 10, a second housing 20, a rotating assembly 30, a flexible screen and a controller 40.

[0023] The first shell 10 and the second shell 20 are movably connected through the rotating assembly 30, so that the electronic device is switched between the folded state and the unfolded state, and the flexible screen is connected with the first shell 10 and the second shell 20 respectively. The rotating assembly 30 comprises a first rotating shaft 31 and a second rotating shaft 32, the first rotating shaft 31 is fixedly connected with the first shell 10, the second rotating shaft 32 is fixedly connected with the second shell 20, the first rotating shaft 31 is provided with a first detection piece 311, the second rotating shaft 32 is provided with a second detection piece 321, and the first detection piece 311 and the second detection piece 321 are used to obtain a detection signal. In the case that the first rotating shaft 31 rotates relative to the second rotating shaft 32, the detection signal changes, and the controller 40 controls the flexible screen to be in a locked state.

[0024] In the embodiment of the present application, since the first shell 10 and the second shell 20 are movably connected through the rotating assembly 30, and the flexible screen is connected with the first shell 10 and the second shell 20 respectively, the first shell 10 and the second shell 20 can be made to approach or move away from each other by applying force to the first shell 10 and the second shell 20, so that the first shell 10 and the second shell 20 drive the flexible screen to unfold or fold, so that the electronic device is switched between the folded state and the unfolded state. Since the first rotating shaft 31 of the rotating assembly 30 is fixedly connected with the first shell 10, and the second rotating shaft 32 is fixedly connected with the second shell 20, when the first shell 10 and the second shell 20 approach or move away from each other, the first shell 10 and the second shell 20 can drive the first rotating shaft 31 and the second rotating shaft 32 to rotate. Since the first rotating shaft 31 is provided with the first detection piece 311, and the second rotating shaft 32 is provided with the second detection piece 321, the detection signal can be obtained through the first detection piece 311 and the second detection piece 312, so that when the detection signal changes, the controller 40 controls the flexible screen to be in a locked state. Specifically, when the first rotating shaft 31 rotates relative to the second rotating shaft 32, the detection signal changes, so that the controller 40 controls the flexible screen to be in a locked state.

[0025] That is, in the embodiment of the present application, by providing the first detection piece 311 on the first rotating shaft 31 and the second detection piece 321 on the second rotating shaft 32, when the first shell 10 and the second shell 20 approach or move away from each other, that is, when the first rotating shaft 31 rotates relative to the second rotating shaft 32, the detection signal changes, so that the controller 40 controls the flexible screen to be in a locked state, so that during the unfolding process or the folding process of the electronic device, the flexible screen can be prevented from being accidentally touched to make the electronic device perform unnecessary operations.

[0026] In addition, in the embodiment of the present application, the second detection member 321 can include insulating portions 3211 and conductive portions 3212, the insulating portions 3211 and the conductive portions 3212 are alternately distributed along the circumferential direction of the second rotating shaft 32; the first detection member 311 is electrically connected with the control assembly 40, and the second detection member 321 is grounded, or the second detection member 321 is electrically connected with the control assembly 40, and the first detection member 311 is grounded. In the case that the electronic device is converted from the folded state to the unfolded state, or the electronic device is converted from the unfolded state to the folded state, that is, in the case that the first rotating shaft 31 rotates relative to the second rotating shaft 32, the first rotating shaft 31 rotates relative to the second rotating shaft 32, the first detection member 311 alternately contacts the insulating portions 3211 and the conductive portions 3212, and the voltage of the control assembly 40 continuously changes, so that the control assembly 40 stops supplying power to the flexible screen, the flexible screen does not respond to touch, and thus the flexible screen is in a locked state.

[0027] In the embodiment of the present application, the second detection member 321 can include insulating portions 3211 and conductive portions 3212, the insulating portions 3211 and the conductive portions 3212 of the second detection member 321 are alternately distributed along the circumferential direction of the second rotating shaft 32, and the first detection member 311 alternately contacts the insulating portions 3211 and the conductive portions 3212 when the first housing 10 and the second housing 20 approach each other or move away from each other, that is, the first detection member 311 contacts the conductive portions 3212, and the first detection member 311 contacts the insulating portions 3211 in turn and alternately as the first rotating rod and the second rotating rod rotate. Since the first detection member 311 is electrically connected with the controller 40, and the second detection member 321 is grounded, or the second detection member 321 is electrically connected with the controller 40, and the first detection member 311 is grounded, therefore, when the first detection member 311 contacts the conductive portions 3212 of the second detection member 321, it is equivalent to that the controller 40 is grounded, so that the voltage of the controller 40 is 0, and when the first detection member 311 contacts the insulating portions 3211 of the second detection member 321, the controller 40 maintains its own voltage. Therefore, during the process that the first housing 10 and the second housing 20 move away from each other or approach each other, the first detection member 311 alternately contacts the insulating portions 3211 and the conductive portions 3212, so that the voltage of the controller 40 continuously changes. When the voltage of the controller 40 continuously changes, the controller 40 executes a target function, that is, the controller 40 stops supplying power to the flexible screen, which is equivalent to that the touch function of the flexible screen no longer works, and the flexible screen is in a locked state. Therefore, during the process that the electronic device is folded or unfolded, the flexible screen can be prevented from being mistakenly touched to cause the electronic device to execute an unnecessary operation.

[0028] It should be noted that when the electronic device is switched from the folded state to the unfolded state, or the electronic device is switched from the unfolded state to the folded state, the voltage of the controller 40 continuously changes, and the controller 40 can also determine the angle of relative rotation of the first shell 10 and the second shell 20, and the controller 40 can also stop supplying power to the flexible screen, that is, control the flexible screen to be in the locked state, and determine the angle of relative rotation of the first shell 10 and the second shell 20.

[0029] In addition, in the embodiment of the present application, the controller 40 can include an interface, the first detection piece 311 is electrically connected to the interface, and the second detection piece 321 is grounded. In the case where the first rotating shaft 31 rotates relative to the second rotating shaft 32, the voltage of the interface continuously changes, and the controller 40 controls the flexible screen to be in the locked state. Alternatively, the second detection piece 321 is electrically connected to the interface, and the first detection piece 311 is grounded. In the case where the first rotating shaft 31 rotates relative to the second rotating shaft 32, the voltage of the interface continuously changes, and the controller 40 controls the flexible screen to be in the locked state.

[0030] When the second detection piece 321 is grounded and the interface is electrically connected to the first detection piece 311, at this time, when the first detection piece 311 contacts the insulating part 3211 of the second detection piece 321, the voltage of the interface is the voltage of itself, that is, the pull-up voltage, and the pull-up voltage can be 1.8V. When the first detection piece 311 contacts the conductive part 3212 of the second detection piece 321, the interface is equivalent to being grounded, so that the voltage of the interface is 0. Thus, the controller 40 can detect the voltage of this interface of itself, so that when the voltage of the interface continuously changes, that is, the voltage of the interface is continuously switched between 0V and 1.8V, that is, the electronic device is switched from the unfolded state to the folded state, or from the folded state to the unfolded state, that is, the first rotating shaft 31 rotates relative to the second rotating shaft 32, the controller 40 stops supplying power to the flexible screen, so that the flexible screen is in the locked state, and the flexible screen is prevented from being accidentally touched to make the electronic device perform unnecessary operations. Similarly, when the first detection piece 311 is grounded and the interface is electrically connected to the second detection piece 321, at this time, when the first detection piece 311 contacts the insulating part 3211 of the second detection piece 321, the voltage of the interface is the voltage of itself, that is, the pull-up voltage, and the pull-up voltage can be 1.8V. When the first detection piece 311 contacts the conductive part 3212 of the second detection piece 321, the interface is equivalent to being grounded, so that the voltage of the interface is 0. Thus, the controller 40 can detect the voltage of this interface of itself, so that when the voltage of the interface continuously changes, that is, the voltage of the interface is continuously switched between 0V and 1.8V, that is, the electronic device is switched from the unfolded state to the folded state, or from the folded state to the unfolded state, that is, the first rotating shaft 31 rotates relative to the second rotating shaft 32, the controller 40 stops supplying power to the flexible screen, so that the flexible screen is in the locked state, and the flexible screen is prevented from being accidentally touched to make the electronic device perform unnecessary operations.

[0031] In addition, in this embodiment, the positional relationship between the insulating part 3211 and the conductive part 3212 of the second detection element 321 can be preset, and the angular relationship between adjacent insulating parts 3211 and conductive parts 3212 can be determined. Thus, after the first detection element 311 contacts the insulating part 3211, when it contacts the conductive part 3212, the voltage of the interface of the controller 40 changes once. The angle value corresponding to this change can be determined. Then, by determining the number of voltage changes of the interface of the controller 40, the relative rotation angle between the first housing 10 and the second housing 20 can be determined.

[0032] For example, the angular relationship between adjacent insulating parts 3211 and conductive parts 3212 is set to correspond to the angle of relative rotation between the first housing 10 and the second housing 20 as 2 degrees. That is, after the first detection element 311 contacts the insulating part 3211, it contacts the conductive part 3212, and the voltage of the interface of the controller 40 changes once. Thus, it can be determined that the angle of relative rotation between the first housing 10 and the second housing 20 is 2 degrees.

[0033] In addition, in this embodiment, the controller 40 can be a control chip with an interface that is electrically connected to the first detection element 311 or to the second detection element 321.

[0034] In some embodiments, a first gear 301 may be provided on the first rotating shaft 31, and a second gear 302 may be provided on the second rotating shaft 32. The first gear 301 and the second gear 302 mesh, and the first gear 301 is connected to the first housing 10, while the second gear 302 is connected to the second housing 20. When the electronic device changes from a folded state to an unfolded state, or vice versa, the first housing 10 drives the first rotating shaft 31 to rotate. The first rotating shaft 31 drives the second gear 302 to rotate via the first gear 301, and the second gear 302 drives the second rotating shaft 32 to rotate.

[0035] Since the first gear 301 on the first rotating shaft 31 meshes with the second gear 302 on the second rotating shaft 32, and the first gear 301 is connected to the first housing 10, while the second gear 302 is connected to the second housing 20, when the electronic device switches from a folded state to an unfolded state, or vice versa, the first housing 10 and the second housing 20 move, that is, they move closer to or further apart. This causes the first housing 10 to move the first gear 301, which in turn rotates along with the first housing 10. The first gear 301 then drives the first rotating shaft 31 to rotate, and in turn, it drives the second gear 302 to rotate, which in turn drives the second rotating shaft 32 to rotate. During the rotation of the first rotating shaft 31 and the second rotating shaft 32, the first detection element 311 alternately contacts the insulating part 3211 and the conductive part 3212 of the second detection element 321, causing the voltage of the controller 40 to change continuously. That is, by setting a first gear 301 on the first rotating shaft 31 and a second gear 302 on the second rotating shaft 32, the first gear 301 and the second gear 302 mesh, which facilitates the rotation of the first rotating shaft 31 and the second rotating shaft 32 during the process of switching the electronic device from the unfolded state to the folded state or from the folded state to the unfolded state, thereby making the insulating part 3211 and the conductive part 3212 of the first detection element 311 and the second detection element 321 alternately contact.

[0036] It should be noted that the first gear 301 has a first through hole, through which it can be sleeved onto the first rotating shaft 31, with the first rotating shaft 31 and the first through hole having an interference fit. The second gear 302 has a second through hole, through which it can be sleeved onto the second rotating shaft 32, with the second rotating shaft 32 and the second through hole having an interference fit. Of course, the first gear 301 can also be welded to the first rotating shaft 31, and the second gear 302 can also be welded to the second rotating shaft 32. This embodiment of the application does not limit the specific choice of gear 301.

[0037] In some embodiments, the electronic device may also include a first connector 33 and a second connector 34. One end of the first connector 33 is fixedly connected to the first housing 10, and the other end of the first connector 33 is fixedly connected to the first gear 301; one end of the second connector 34 is fixedly connected to the second housing 20, and the other end of the second connector 34 is fixedly connected to the second gear 302.

[0038] When the electronic device includes a first connector 33 and a second connector 34, one end of the first connector 33 can be directly fixedly connected to the first housing 10, and the other end of the first connector 33 can be fixedly connected to the first gear 301, thereby connecting the first gear 301 to the first housing 10 through the first connector 33, which is beneficial for the connection between the first gear 301 and the first housing 10. Similarly, one end of the second connector 34 can be directly fixedly connected to the second housing 20, and the other end of the second connector 34 can be fixedly connected to the second gear 302, thereby connecting the second gear 302 to the second housing 20 through the second connector 34, which is beneficial for the connection between the second gear 302 and the second housing 20.

[0039] It should be noted that the first connecting member 33 can be a connecting rod or a connecting block. The specific type of the first connecting member 33 is not limited in this embodiment. Similarly, the second connecting member 34 can be a connecting rod or a connecting block. The specific type of the second connecting member 34 is not limited in this embodiment.

[0040] In addition, in this embodiment, a snap-fit ​​groove may be provided on the first housing 10, and one end of the first connector 33 may be snapped into the snap-fit ​​groove, thereby fixing the first connector 33 to the first housing 10. Of course, one end of the first connector 33 may also be welded to the first housing 10, thereby fixing one end of the first connector 33 to the first housing 10. The method of fixing the first connector 33 to the first housing 10 is not limited in this embodiment. A snap-fit ​​groove may be provided on the second housing 20, and one end of the second connector 34 may be snapped into the snap-fit ​​groove, thereby fixing the second connector 34 to the second housing 20. Of course, one end of the second connector 34 may also be welded to the second housing 20, thereby fixing one end of the second connector 34 to the second housing 20. The method of fixing the second connector 34 to the second housing 20 is not limited in this embodiment.

[0041] In addition, in this embodiment, the first gear 301 can be directly welded to the first housing 10, thereby connecting the first gear 301 to the first housing 10, and the second gear 302 can also be directly welded to the second housing 20, thereby connecting the second gear 302 to the second housing 20.

[0042] In some embodiments, the first detection element includes a conductive contact disposed on the first rotating shaft 31. The second detection element 321 can be a gear with multiple insulating detection teeth. A conductive element is disposed between any two adjacent insulating detection teeth. The conductive element is grounded or electrically connected to the controller 40. When the first rotating shaft 31 rotates relative to the second rotating shaft 32, the conductive contact alternately contacts the insulating detection teeth and the conductive element. The detection signal acquired by the conductive contact changes, and the controller 40 controls the flexible screen to be in a locked state.

[0043] When the second detection element 321 is a gear with multiple insulating detection teeth and a conductive element is provided between any two adjacent insulating detection teeth, the insulating detection teeth and the conductive element change positions around the circumferential direction of the second rotating shaft 32 during the rotation of the second rotating shaft 32. As a result, the first detection element 311 will alternately contact the insulating detection teeth and the conductive element. That is, the conductive contact will alternately contact the insulating detection teeth and the conductive element. As a result, the voltage on the conductive contact will change. That is, when the conductive contact is in contact with the insulating detection teeth, the voltage on the conductive contact is the first voltage, and when the conductive contact is in contact with the conductive element, the voltage on the conductive contact is the second voltage. As a result, the voltage of the controller 40 will also change continuously, and the controller 40 will control the flexible screen to be in a locked state. Alternatively, during the rotation of the first rotating shaft 31, the first detection element 311 rotates along with the first rotating shaft 31, thereby alternating contact between the first detection element 311 and the insulating detection teeth and the conductive element. That is, the conductive contact alternately contacts the insulating detection teeth and the conductive element, causing the voltage on the conductive contact to change. Specifically, when the conductive contact contacts the insulating detection teeth, the voltage on the conductive contact is a first voltage; when the conductive contact contacts the conductive element, the voltage on the conductive contact is a second voltage. Consequently, the voltage of the controller 40 also changes continuously, and the controller 40 controls the flexible screen to be in a locked state. Furthermore, by setting the second detection element 321 as a gear, and the gear having insulating detection teeth and a conductive element, the second detection element 321 can be easily formed, making it easier to process.

[0044] It should be noted that the conductive component can be a metal sheet, and the gear can be a metal gear. Multiple teeth of the metal gear can be coated with an insulating layer, making these teeth insulation detection teeth, with a metal sheet placed between any two adjacent teeth. Alternatively, the gear can be made of a non-metallic material, with a metal sheet placed between any two adjacent teeth. Furthermore, the insulation detection teeth can form an insulating portion 3211, and the conductive component can form a conductive portion 3212.

[0045] Of course, in the embodiments of this application, the insulating part 3211 can also be of other types, not limited to tooth shape. For example, the insulating part 3211 is a cylindrical boss, and the conductive part 3212 can also be of other types, not limited to tooth shape. For example, the conductive part 3211 is a cylindrical boss.

[0046] In some embodiments, the first detection element 311 may also include a base 3111, and the conductive contact includes a conductive elastic element 3112 and a conductive pin 3113. The base 3111 is connected to the first rotating shaft 31, and a mounting groove is provided on the base 3111. The conductive elastic element 3112 is installed in the mounting groove, and one end of the conductive elastic element 3112 is fixedly connected to the bottom of the mounting groove. The conductive pin 3113 is fixedly connected to the other end of the conductive elastic element 3112. The conductive elastic element 3112 is grounded, or the conductive elastic element 3112 is electrically connected to the controller 40. When the first rotating shaft 31 rotates relative to the second rotating shaft 32, the conductive elastic element 3112 drives the conductive pin 3113 to move, so that the conductive pin 3113 alternately contacts the insulating detection teeth and the conductive element. The detection signal acquired by the conductive pin 3113 changes, and the controller 40 controls the flexible screen to be in a locked state.

[0047] When the base 3111 is connected to the first rotating shaft 31, and the base 3111 is provided with a mounting groove, the conductive elastic element 3112 is installed in the mounting groove, and one end of the conductive elastic element 3112 is fixedly connected to the bottom of the mounting groove, and the conductive pin 3113 is fixedly connected to the other end of the conductive elastic element 3112, when the first rotating shaft 31 and the second rotating shaft 32 rotate, the conductive pin 3113 will move along the extension and retraction direction of the conductive elastic element 3112 under the action of the conductive elastic element 3112, so that the conductive pin 3113 will alternately contact the insulating part 3211 and the conductive part 3212 of the second detection element 321. Specifically, when the electronic device changes from a folded state to an unfolded state, or from an unfolded state to a folded state, the first housing 10 and the second housing 20 move away from each other or move closer to each other, causing the first rotating shaft 31 and the second rotating shaft 32 to rotate. After the conductive pin 3113 on the first rotating shaft 31 contacts the insulation detection teeth, as the first rotating shaft 31 rotates, the conductive pin 3113 will be subjected to the force of the insulation detection teeth, thereby causing the conductive elastic element 3112 to contract, and thus the conductive pin 3113 to contract. Then, as the first rotating shaft 31 continues to rotate, the conductive pin 3113 will move to the position of the conductive element, and the conductive elastic element 3112 will apply force to the conductive pin 3113, causing the conductive pin 3113 to contact the conductive element. During the rotation of the first rotating shaft 31 and the second rotating shaft 32, the conductive pin 3113, under the action of the insulating elastic element, alternately contacts the insulating detection tooth and the conductive element, thereby changing the voltage on the conductive pin 3113. Specifically, when the conductive pin 3113 contacts the insulating detection tooth, the voltage on the conductive pin 3113 is the first voltage; when the conductive pin 3113 contacts the conductive element, the voltage on the conductive pin 3113 is the second voltage. This causes the voltage of the controller 40 to change continuously, and the controller 40 controls the flexible screen to be in a locked state. Furthermore, in this embodiment, the base 3111 is insulated from the first rotating shaft 31, meaning there is no electrical conductivity between the base 3111 and the first rotating shaft 31. This prevents the conductive elastic element 3112 from transferring electrical energy to the base 3111 and then to the first rotating shaft 31, thus avoiding leakage in the electronic device.

[0048] It should be noted that the conductive elastic element 3112 can be a metal spring. Of course, the conductive elastic element 3112 can also be other types, such as a metal sheet. The specific type of the conductive elastic element 3112 is not limited in this embodiment.

[0049] In addition, in this embodiment, the surface of the base 3111 can be coated with an insulating material, and then the base 3111 is bonded to the first rotating shaft 31. This can prevent the surface of the base 3111 from becoming conductive, thereby avoiding leakage of current in the electronic device due to the function of the base 3111. Of course, the base 3111 can also be made of an insulating material, in which case the base 3111 and the first rotating shaft 31 are also insulated.

[0050] In some embodiments, an insulating ring 312 may be fitted on the first rotating shaft 31, and a base 3111 may be disposed on the insulating ring 312.

[0051] By fitting an insulating ring 312 onto the first rotating shaft 31, the base 3111 is placed on the insulating ring 312. When it is necessary to connect the base 3111 to the first rotating shaft 31, the insulating ring 312 can be directly fitted onto the first rotating shaft 31, which facilitates the connection between the base 3111 and the first rotating shaft 31 and ensures insulation between the base 3111 and the first rotating shaft 31.

[0052] It should be noted that the insulating ring 312 can be made of non-conductive materials such as rubber or plastic.

[0053] In addition, in some embodiments, a plurality of limiting members 313 may be provided on the first rotating shaft 31, the plurality of limiting members 313 being spaced apart, the insulating ring 312 being located between two adjacent limiting members 313, and the insulating ring 312 abutting against the limiting member 313, the limiting member 313 being used to limit the insulating ring 312 in the axial direction of the first rotating shaft 31.

[0054] When multiple limiting members 313 are provided on the first rotating shaft 31, and the insulating ring 312 is located between two adjacent limiting members 313 and abuts against the limiting member 313, the limiting member 313 can limit the insulating ring 312 in the axial direction of the first rotating shaft 31, thus preventing the insulating ring 312 from moving along the axial direction of the first rotating shaft 31. In other words, by providing the limiting member 313, the position of the insulating ring 312 on the first rotating shaft 31 can be fixed, preventing the insulating ring 312 from moving along the axial direction of the first rotating shaft 31 during rotation.

[0055] It should be noted that the limiting member 313 can be fixed on the first rotating shaft 31, and in the axial direction of the first rotating shaft 31, the limiting member 313 can be located on opposite sides of the insulating ring 312 and abut against the insulating ring 312, so that the limiting member 313 can limit the insulating ring 312 in the axial direction of the first rotating shaft 31.

[0056] In some embodiments, the rotating assembly 30 may further include a first fixing rod 35 and a second fixing rod 36. The first fixing rod 35 is connected to the first housing 10, the second fixing rod 36 is connected to the second housing 20, the first rotating shaft 31 is rotatably connected to the first fixing rod 35, and the second rotating shaft 32 is rotatably connected to the second fixing rod 36. When the electronic device changes from a folded state to an unfolded state, or vice versa, the first fixing rod 35 and the second fixing rod 36 remain stationary, the first rotating shaft 31 rotates relative to the first fixing rod 35, and the second rotating shaft 32 rotates relative to the second fixing rod 36.

[0057] When the first fixing rod 35 is connected to the first housing 10, the second fixing rod 36 is connected to the second housing 20, the first rotating shaft 31 is rotatably connected to the first fixing rod 35, and the second rotating shaft 32 is rotatably connected to the second fixing rod 36, at this time, when the electronic device switches from the unfolded state to the folded state, or from the folded state to the unfolded state, the first housing 10 and the second housing 20 move closer to each other or further away from each other, so that the positions of the first housing 10 and the second housing 20 change. The first fixing rod 35 and the second fixing rod 36 remain stationary, that is, the first fixing rod 35 does not rotate, and the second fixing rod 36 does not rotate either. However, the first rotating shaft 31 rotates relative to the first fixing rod 35, and the second rotating shaft 32 rotates relative to the second fixing rod 36, so that the insulating part 3211 and the conductive part 3212 of the first detection element 311 on the first rotating shaft 31 and the second detection element 321 on the second rotating shaft 32 alternately contact each other. In addition, by setting the first fixing rod 35 and the second fixing rod 36, it is convenient to set the first rotating shaft 31 and the second rotating shaft 32. The first fixing rod 35 and the second fixing rod 36 provide the installation position for the first rotating shaft 31 and the second rotating shaft 32, which facilitates the installation of the first rotating shaft 31 and the second rotating shaft 32.

[0058] It should be noted that a rotating boss can be provided on the first fixed rod 35, and the first rotating shaft 31 has a rotating hole. The first rotating shaft 31 is sleeved on the rotating boss through the rotating hole, so that the first rotating shaft 31 can rotate relative to the first fixed rod 35. Similarly, a rotating boss can be provided on the second fixed rod 36, and the second rotating shaft 32 has a rotating hole. The second rotating shaft 32 is sleeved on the rotating boss through the rotating hole, so that the second rotating shaft 32 can rotate relative to the second fixed rod 36. Of course, a rotating hole can be provided on the first fixed rod 35, and a rotating boss can be provided on the first rotating shaft 31, with the rotating boss embedded in the rotating hole, so that the first rotating shaft 31 can rotate relative to the first fixed rod 35. This embodiment of the present application does not limit this. Of course, a rotating hole can be provided on the second fixed rod 36, and a rotating boss can be provided on the second rotating shaft 32, with the rotating boss embedded in the rotating hole, so that the second rotating shaft 32 can rotate relative to the second fixed rod 36. This embodiment of the present application does not limit this.

[0059] In some embodiments, a conductive connector 351 may be provided on the first fixing rod 35. The conductive connector 351 is connected to the first detection element 311 through the conductive rod 352. The conductive connector 351 is grounded or electrically connected to the controller 40.

[0060] When a conductive connector 351 is provided on the first fixing rod 35, and the conductive connector 351 is connected to the first detection element 311 via a conductive rod 352, then regardless of whether the conductive connector 351 is grounded or electrically connected to the controller 40, the controller 40 will be grounded when the first detection element 311 contacts the conductive part 3212 of the second detection element 321, resulting in a voltage of 0 for the controller 40. When the first detection element 311 contacts the insulating part 3211 of the second detection element 321, the voltage of the controller 40 will be its own voltage. Therefore, the voltage of the controller 40 can change continuously when the electronic device is folded or unfolded. Furthermore, by providing the conductive connector 351, which is electrically connected to the first detection element 311 via a connecting rod, it is easier to arrange the first detection element 311 within the electronic device, resulting in a more rational deployment of components and improving the space utilization of the electronic device.

[0061] It should be noted that a snap-fit ​​groove can be provided on the conductive connector 351, and one end of the conductive rod 352 is snapped into the snap-fit ​​groove. The other end of the first detection element 311 is connected to the first detection element 311. When the first detection element 311 includes a base 3111, a conductive elastic element 3112, and a conductive pin 3113, a snap-fit ​​hole can be provided on the base 3111, and the other end of the conductive rod 352 is snapped into the snap-fit ​​hole. The conductive rod 352 is electrically connected to the conductive elastic element 3112, so that when the conductive pin 3113 contacts the conductive part 3212 of the second detection element 321, the voltage of the controller 40 can be 0.

[0062] In addition, when the conductive connector 351 is provided with a snap-fit ​​groove, the groove wall of the snap-fit ​​groove can conduct electricity, while the conductive connector 351 is not conductive. That is, only the groove wall of the snap-fit ​​groove in the conductive connector 351 is conductive.

[0063] In addition, in some embodiments, if the duration of contact between the first detection element 311 and the conductive part 3212 is longer than a preset duration, the controller 40 supplies power to the flexible screen so that the flexible screen responds to touch.

[0064] When the contact time between the first detection element 311 and the conductive part 3212 exceeds a preset time, it indicates that during the process of switching the electronic device from an unfolded state to a folded state, or vice versa, the user may stop applying force to the electronic device, and the user may need to use the electronic device. Therefore, the controller 40 supplies power to the flexible screen, and the flexible screen can then respond to touch input; that is, when the user performs a touch operation on the flexible screen, the flexible screen can respond. Alternatively, when the contact time between the first detection element 311 and the conductive part 3212 exceeds a preset time, it may also indicate that the electronic device has been fully unfolded or fully folded, and the user may need to use the electronic device. Therefore, the controller 40 supplies power to the flexible screen, and the flexible screen can then respond to touch input; that is, when the user performs a touch operation on the flexible screen, the flexible screen can respond.

[0065] In some embodiments, the electronic device may further include a first control switch 50, a first drive circuit 60, a second control switch 70, and a second drive circuit 80. The first drive circuit 60 is electrically connected to the first control switch 50, and the second drive circuit 80 is electrically connected to the second control switch 70. The controller 40 is electrically connected to both the first control switch 50 and the second control switch 70. The first control switch 50 is electrically connected to the flexible screen, and the second control switch 70 is electrically connected to the flexible screen. When the voltage of the controller 40 changes continuously, the controller 40 controls the first control switch 50 and the second control switch 70 to disconnect, and the first drive circuit 60 stops supplying power to the flexible screen, and the second drive circuit 80 stops supplying power to the flexible screen. When the contact time between the first detection element 311 and the conductive part 3212 is longer than a preset time, the controller 40 controls the first control switch 50 and the second control switch 70 to connect, and the first drive circuit 60 supplies power to the flexible screen, and the second drive circuit 80 supplies power to the flexible screen.

[0066] Since the first driving circuit 60 is electrically connected to the first control switch 50, the second driving circuit 80 is electrically connected to the second control switch 70, and the controller 40 is electrically connected to both the first control switch 50 and the second control switch 70, the first control switch 50 is electrically connected to the flexible screen, and the second control switch 70 is electrically connected to the flexible screen, when the controller 40 controls the first control switch 50 and the second control switch 70 to open, the electrical energy of the first driving circuit 60 and the second driving circuit 80 cannot be transferred to the flexible screen, so the flexible screen will not respond to touch. When the controller 40 controls the first control switch 50 and the second control switch 70 to close, the electrical energy of the first driving circuit 60 and the second driving circuit 80 cannot be transferred to the flexible screen, so the flexible screen will respond to touch. Specifically, when the voltage of the controller 40 changes continuously, it is equivalent to the user switching the electronic device from a folded state to an unfolded state, or vice versa. The controller 40 controls the first control switch 50 and the second control switch 70 to disconnect, the first drive circuit 60 stops supplying power to the flexible screen, and the second drive circuit 80 stops supplying power to the flexible screen. This can prevent the electronic device from performing unnecessary operations due to accidental touches by the user. When the contact time between the first detection element 311 and the conductive part 3212 is longer than the preset time, it is equivalent to the user having finished unfolding or folding the electronic device. When the user needs to use the electronic device, the controller 40 controls the first control switch 50 and the second control switch 70 to turn on, the first drive circuit 60 supplies power to the flexible screen, and the second drive circuit 80 supplies power to the flexible screen. Thus, the flexible screen can respond to the user's touch operation.

[0067] It should be noted that the first inspection component 311 and the second inspection component 321 are equivalent to Figure 6 In this equivalent switch, when the insulating part 3211 of the first detection element 311 contacts the second detection element 321, it is equivalent to the equivalent switch being open; when the conductive part 3212 of the first detection element 311 and the second detection element 321 contacts the second detection element 321, it is equivalent to the equivalent switch being closed. When the equivalent switch is open, the interface of the controller 40 is its own pull-up voltage; when the equivalent switch is closed, the interface of the controller 40 is grounded, and thus the voltage of the interface is 0. The controller 40 can perform different functions by detecting the voltage of the interface. In addition, in this embodiment, by setting the first detection element 311 and the second detection element 321, it is equivalent to the first detection element 311 and the second detection element 321 being equivalent to a switch. That is, by using a mechanical structure to replace the control switch in the electronic device, the number of electronic components in the electronic device is reduced, which is beneficial to saving electronic energy.

[0068] It should also be noted that the first control switch 50 can be an Insulated Gate Bipolar Transistor (IGBT), but it can also be other types. For example, the first control switch 50 can also be a MOSFET. The specific type of the first control switch 50 is not limited in this embodiment. Similarly, the second control switch 70 can be an IGBT, but it can also be other types. For example, the second control switch 70 can also be a MOSFET. The specific type of the second control switch 70 is not limited in this embodiment.

[0069] In addition, in this embodiment, when the detection signal acquired by the controller 40 changes continuously, the controller 40 sends a high-level signal to the first control switch 50 and the second control switch 70 to disconnect the first control switch 50 and the second control switch 70; when the detection signal acquired by the controller 40 remains unchanged and the duration of the unchanged detection signal is longer than a preset duration, the controller 40 sends a low-level signal to the first control switch 50 and the second control switch 70 to turn on the first control switch 50 and the second control switch 70.

[0070] Specifically, when the first control switch 50 and the second control switch 70 receive different level signals, their states will also differ. Specifically, when both the first control switch 50 and the second control switch 70 receive a high-level signal, they are open (disconnected); when both receive a low-level signal, they are on (conducted). Thus, the controller 40 can send different level signals to the first control switch 50 and the second control switch 70, causing the first control switch 50 to turn on or off, and the second control switch 70 to turn on or off, respectively.

[0071] In addition, in some embodiments, the first detection element 311 may include a magnetic sensor, and the second detection element 321 may include a plurality of magnetic elements, and the plurality of magnetic elements are distributed at intervals along the circumferential direction of the second rotating shaft 32; when the first rotating shaft 31 rotates relative to the second rotating shaft 32, the information of the magnetic elements sensed by the magnetic sensor changes.

[0072] When multiple magnetic components are spaced apart along the circumferential direction of the second rotating shaft 32, as the first rotating shaft 31 rotates relative to the second rotating shaft 32, the first rotating shaft 31 drives the magnetic sensor to rotate, thus the magnetic sensor will intermittently detect the magnetic components. For example, the magnetic sensor may initially detect one magnetic component. If, during the rotation of the first rotating shaft 31, the magnetic sensor moves towards the gap between two magnetic components, it will not detect any magnetic components and therefore will not receive a detection signal. However, if the first rotating shaft 31 continues to rotate and the magnetic sensor moves towards another magnetic component, it will detect the magnetic component again and receive a detection signal. Thus, as the magnetic sensor rotates with the first rotating shaft 31, it senses information about the magnetic components, and then loses that information. This process is continuous. Changes in the information sensed by the magnetic sensor trigger a command to the controller, which then locks the flexible screen. Similarly, when the second rotating shaft 32 rotates relative to the first rotating shaft 31, the information sensed by the magnetic sensor also changes, triggering a command to the controller, which then locks the flexible screen. That is, during the process of switching the electronic device from a folded state to an unfolded state, or from an unfolded state to a folded state, the controller 40 will control the flexible screen to be locked.

[0073] In some embodiments, the first detection element 311 may include either a capacitive sensor or a resistive sensor.

[0074] When the first detection element 311 is a capacitive sensor, the capacitance of the second rotating shaft 32 can be set so that the detection value of the capacitive sensor changes when the first rotating shaft 31 rotates relative to the second rotating shaft 32. When the first detection element 311 is a resistive sensor, the resistance of the second rotating shaft 32 can be set so that the detection value of the capacitive sensor changes when the first rotating shaft 31 rotates relative to the second rotating shaft 32.

[0075] In addition, in the embodiments of this application, electronic devices include, but are not limited to, mobile phones, tablets, laptops, handheld computers, vehicle terminals, wearable devices, and pedometers.

[0076] In this embodiment, since the first housing 10 and the second housing 20 are movably connected via a rotating assembly 30, and the flexible screen is connected to both the first housing 10 and the second housing 20, force can be applied to the first housing 10 and the second housing 20 to move them closer or further apart, thereby causing the flexible screen to unfold or fold, allowing the electronic device to switch between a folded and unfolded state. Since the first rotating shaft 31 of the rotating assembly 30 is fixedly connected to the first housing 10, and the second rotating shaft 32 is fixedly connected to the second housing 20, the first housing 10 and the second housing 20 can rotate the first rotating shaft 31 and the second rotating shaft 32 when they move closer or further apart. Since the first rotating shaft 31 is provided with a first detection element 311, and the second rotating shaft 32 is provided with a second detection element 321, detection signals can be obtained through the first detection element 311 and the second detection element 312. Therefore, when the detection signals change, the controller 40 controls the flexible screen to be in a locked state. Specifically, when the first rotating shaft 31 rotates relative to the second rotating shaft 32, the detection signal changes, and the controller 40 then controls the flexible screen to be in a locked state.

[0077] That is, in this embodiment of the application, by setting a first detection element 311 on the first rotating shaft 31 and a second detection element 321 on the second rotating shaft 32, the detection signal will change when the first housing 10 and the second housing 20 approach each other or move away from each other, that is, when the first rotating shaft 31 rotates relative to the second rotating shaft 32. As a result, the controller 40 controls the flexible screen to be in a locked state, thereby preventing the flexible screen from being accidentally touched and causing the electronic device to perform unnecessary operations during the unfolding or folding process of the electronic device.

[0078] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or terminal device.
