[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0049] The following is combined with Figures 1 to 7 As shown, the electronic device provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0050] like Figures 1 to 5 As shown, the electronic device of the embodiment of the present application includes: a housing, a swing arm 20, and the housing may include a first housing 30, a second housing 34 and a rotating part 10, and the first housing 30 and the second housing 34 are rotatably connected through the rotating part 10. The rotating part 10 includes a hinge structure. Specifically, the hinge structure includes a first rotating shaft 11, and the first housing 30 and the second housing 34 are rotatably connected through the first rotating shaft. The rotating part 10 also includes a coating layer connected to the first housing 30 and the second housing 34 to cover the hinge structure. The coating layer can be an elastic layer to reduce the impact between the rotating part 10 and the ground when the electronic device falls. One end of the swing arm 20 is connected to the first housing 30, and the other end of the swing arm 20 is connected to the rotating part 10. One end of the swing arm 20 is connected to the first housing 30 so as to be relatively movable. The swing arm 20 is a fixed swing arm, that is, the other end of the swing arm 20 is fixedly connected to the rotating part 10 to ensure that the swing arm 20 can rotate synchronously with the rotating part 10, thereby driving the first housing 30 to rotate synchronously with the rotating part 10. In some embodiments, the swing arm 20 may be rotatably connected to the rotating part 10 , that is, the swing arm 20 may serve as a virtual swing arm and a certain relative rotation space may be reserved between the swing arm and the rotating part 10 .

[0051] The first shell 30 and the second shell 34 can be relatively folded or unfolded by the rotating part 10. The first shell 30 and the second shell 34 can be connected to a display screen, which can be a flexible screen. Both ends of the display screen can be connected to the corresponding shells. The display screen can be folded by folding the shell, and can be unfolded by unfolding the shell.

[0052] The swing arm 20 is provided with a first limiting structure 50, and the housing is provided with a second limiting structure 60. In the illustrated embodiment, the second limiting structure 60 may be provided on the first housing 30 or the second housing 34. When the electronic device is in a folded state, the first limiting structure 50 abuts against the second limiting structure 60 to limit the movement of the housing. For example, when the electronic device is in a folded state, the first limiting structure 50 is clamped on the second limiting structure 60.

[0053] When the electronic device is in the unfolded state, the first limiting structure 50 is separated from the second limiting structure 60, and the swing arm 20 and the housing can move relative to each other without affecting the rotation, so as to facilitate the unfolding or folding of the housing.

[0054] When the electronic device is in the folded state, the first limiting structure 50 abuts against the second limiting structure 60. When the electronic device is in the folded state and falls to the ground, since the first limiting structure 50 abuts against the second limiting structure 60, the swing arm 20 and the housing will not move relative to each other, so that the rotating part will not squeeze the display screen due to the reduction of the accommodation space caused by sliding, and the water drop area of ​​the display screen is not prone to deformation, damage, etc., which prevents the display screen from failing and improves the safety of the display screen when the device falls.

[0055] In some embodiments, the rotating part 10 may include a first rotating shaft 11, and the swing arm 20 is fixedly connected to the first rotating shaft 11 so that the swing arm 20 and the first rotating shaft 11 rotate synchronously. When the electronic device is in a folded state, the first limiting structure 50 and the second limiting structure 60 abut to limit along a first direction, and the angle between the first direction and the extension direction of the first rotating shaft 11 is less than 180°, so that when the rotating part is hit by the device falling, the shell is not easy to slide downward, and the water drop area of ​​the display screen on the shell is not easy to be deformed, damaged, etc., thereby improving the safety of the display screen when the device falls. Figure 1 and Figure 2 In the embodiment shown, Figure 1 a in the figure is the extension direction of the first rotating shaft 11, a indicates the direction perpendicular to the paper and outward, b is the first direction, b indicates the vertical downward direction, and the first direction is perpendicular to the extension direction of the first rotating shaft 11, which can avoid to the greatest extent that when the device falls in the folded state and the rotating part 10 faces downward, the bending area of ​​the display screen is damaged by the sliding of the rotating part 10 relative to the first shell 30 and / or the second shell 34 under the action of external force. In other embodiments, in order to effectively protect the bending area of ​​the display screen, the angle between the first direction and the extension direction of the first rotating shaft 11 should be between 45° and 135°.

[0056] In the embodiments of the present application, Figures 1 to 5As shown, the first limiting structure 50 has a stopper, and the second limiting structure 60 includes a limit groove provided on the first housing 30; or, the first limiting structure 50 includes a limit groove provided on the swing arm 20, and the second limiting structure 60 has a stopper. The stopper may be convex, rod-shaped, plate-shaped, strip-shaped, etc., and the shape and size of the limit groove may match the stopper, so that the stopper may be engaged or disengaged from the limit groove. The first limiting structure 50 may be a limit plate, and the second limiting structure 60 may be a limit groove, so as to facilitate the engagement and disengagement between the first limiting structure 50 and the second limiting structure 60. When the electronic device is in an unfolded state, the limit plate may be disengaged from the limit groove, and the swing arm 20 and the housing may move relative to each other. When the electronic device is in a folded state, the limit plate may be engaged in the limit groove, and the swing arm 20 and the housing may not move relative to each other. When the rotating part is impacted, the housing is not likely to slide downward, and the display screen on the housing is not likely to be deformed and damaged. When the electronic device is in the unfolded state, the first limiting structure 50 and the second limiting structure 60 are disengaged, and the surface of the first limiting structure 50 and the swing arm 20 can be flush, and the swing arm 20 and the housing can move relative to each other without restriction.

[0057] exist Figure 1 and Figure 2 In the illustrated embodiment, the first limiting structure 50 is a clamping plate, and the second limiting structure 60 is a clamping slot, and the first limiting structure 50 and the second limiting structure 60 can be clamped or disengaged. In other embodiments, the first limiting structure 50 can be a clamping slot, and the second limiting structure 60 can be a clamping plate, which will not be described in detail here.

[0058] like Figure 1 to Figure 2 As shown, the first housing 30 may include a main frame 31 and a bracket 32, the main frame 31 and the bracket 32 ​​are connected, the main frame 31 and the bracket 32 ​​may be fixedly connected, the main frame 31 and the bracket 32 ​​may be integrally formed, the bracket 32 ​​may be provided with a slide 33, the swing arm 20 may be movably arranged in the slide 33, and the swing arm 20 may move relative to the first housing 30 through the movement of the swing arm 20 in the slide 33, so as to facilitate the folding or unfolding of the electronic device. The second housing 34 may include a main frame 36 and a bracket 35, and the specific structure of the second housing 34 may be the same as that of the first housing 30, and the specific structure may refer to the first housing 30.

[0059] In some embodiments of the present application, the swing arm 20 may also be a virtual swing arm, one end of the virtual swing arm may be connected to the rotating portion 10, and the other end of the virtual swing arm may be connected to the first shell or the second shell. For example, one end of the virtual swing arm may be rotatably connected to the rotating portion 10, and the other end of the virtual swing arm may be rotatably connected to the first shell 30. During the folding or unfolding process of the electronic device, the shell and the swing arm 20 may be driven to move relative to each other through the virtual swing arm, so as to fold or unfold the electronic device.

[0060] like Figure 1 to Figure 2 As shown, a swing arm 20 may also be connected to the second housing 34, and the specific arrangement of the swing arm 20 on the second housing 34 may be the same as the arrangement of the swing arm 20 on the first housing 30. One end of the swing arm 20 is connected to the second housing 34, and the other end of the swing arm 20 connected to the second housing 34 is connected to the rotating part 10. One end of the swing arm 20 and the second housing 34 can be relatively movably connected, and the other end of the swing arm 20 and the rotating part 10 can be rotatably connected. The swing arm 20 on the second housing 34 may be provided with a first limiting structure 50, and the second housing 34 may be provided with a second limiting structure 60. When the electronic device is in a folded state, the first limiting structure 50 may abut against the second limiting structure 60 to limit the movement of the housing. For example, when the electronic device is in a folded state, the first limiting structure 50 may be clamped on the second limiting structure 60; when the electronic device is in an unfolded state, the first limiting structure 50 is separated from the second limiting structure 60, and the swing arm 20 and the housing can move relatively without affecting the rotation, so as to facilitate the unfolding or folding of the housing.

[0061] In some embodiments, the first limiting structure 50 is rotatably disposed on the swing arm 20, and the electronic device includes a driving structure for driving the first limiting structure 50 to rotate, and the driving structure drives the first limiting structure 50 to rotate so that the first limiting structure 50 abuts against or separates from the second limiting structure 60. For example, the driving structure may include a driving motor, an electromagnet, an elastic member, or an electro-deformable member, and the driving structure drives the first limiting structure 50 to rotate, and the driving structure may drive the first limiting structure 50 to abut against or separate from the second limiting structure 60.

[0062] In the embodiments of the present application, Figures 1 to 5 As shown, the swing arm 20 is provided with an opening 21, and the first limiting structure 50 is rotatably disposed in the opening 21. When the first limiting structure 50 rotates to abut against the second limiting structure 60, the stopper of the first limiting structure 50 extends out of the opening 21, so that the first limiting structure 50 and the second limiting structure 60 abut; when the first limiting structure 50 rotates to separate from the second limiting structure 60, the stopper of the first limiting structure 50 is accommodated in the opening 21 to avoid interfering with the folding of the electronic device. The first limiting structure 50 is disposed in the opening 21 to reduce the space occupied, which is conducive to the reduction of the overall structure.

[0063] Alternatively, if Figure 5As shown, the first limiting structure 50 is a limiting plate, the second limiting structure 60 is a limiting groove, and a limiting pin 51 is provided on the first limiting structure 50. The limiting pin 51 can be a high-strength metal material and is not easy to deform. The edge of the first limiting structure 50 is provided with a limiting pin 51, and the edge of the first limiting structure 50 can be provided with at least one limiting pin 51, for example, the edge of the first limiting structure 50 can be provided with two limiting pins 51. When the first limiting structure 50 is engaged in the limiting groove, the limiting pin 51 can be stopped at the side of the swing arm 20 away from the opening 21 to limit the rotation range of the first limiting structure 50. The first limiting structure 50 can rotate, and the rotation range of the first limiting structure 50 can be limited by the limiting pin 51, so that the first limiting structure 50 rotates within a certain range, so that the first limiting structure 50 can stably engage or disengage from the second limiting structure 60.

[0064] In some embodiments, Figures 1 to 5 As shown, the driving structure includes a first driving component 71 and a second driving component 72. The first driving component 71 drives the first limiting structure 50 to rotate so that the first limiting structure 50 abuts against the second limiting structure 60; the second driving component 72 drives the first limiting structure 50 to rotate so that the first limiting structure 50 is separated from the second limiting structure 60. For example, the first driving component 71 can drive the first limiting structure 50 to rotate along the first rotation direction, and the first driving component 71 drives the first limiting structure 50 to abut against the second limiting structure 60. The second driving component 72 can drive the first limiting structure 50 to rotate along the second rotation direction, and the second limiting structure 60 drives the first limiting structure 50 to be separated from the second limiting structure 60. The first rotation direction is opposite to the second rotation direction. The first limiting structure 50 is driven to rotate by the first driving component 71 and the second driving component 72, so that the first limiting structure 50 abuts against or separates from the second limiting structure 60.

[0065] In an embodiment of the present application, the first driving component 71 includes a first magnetic part and a second magnetic part, the first magnetic part is arranged on the first limiting structure 50, and the second magnetic part is arranged on the first shell 30. When the electronic device is in a folded state, the first magnetic part and the second magnetic part are attracted to rotate the first limiting structure 50 to abut against the second limiting structure 60 for limiting. At least one of the first magnetic part and the second magnetic part may include an electromagnet, for example, the first magnetic part may include an electromagnet, and the second magnetic part may include a magnetic member; or the first magnetic part may include a magnetic member, and the second magnetic part includes an electromagnet. The first limiting structure 50 is provided with a first magnetic part, the first magnetic part may include a magnetic member, the first limiting structure 50 may be a magnetic material member, and the second magnetic part may include an electromagnet. When the coil of the electromagnet inputs current, the electromagnet has magnetism. Through the magnetic force of the electromagnet, the electromagnet can drive the first limiting structure 50 to rotate along the first rotation direction, so that the first driving component 71 drives the first limiting structure 50 to abut against the second limiting structure 60.

[0066] Optionally, the second drive assembly 72 includes an elastic member, and the elastic member drives the first limiting structure 50 to rotate to separate from the second limiting structure 60 for reset. The elastic member drives the first limiting structure 50 to rotate along the second rotation direction, and the elastic member drives the first limiting structure 50 to disengage from the second limiting structure 60. When the coil of the electromagnet is not input with current, the elastic member drives the first limiting structure 50 to rotate along the second rotation direction. When the coil of the electromagnet is input with current, the electromagnet has magnetism, and through the magnetic force of the electromagnet, the magnetic force of the electromagnet is greater than the force of the elastic member, the electromagnet can drive the first limiting structure 50 to rotate along the first rotation direction, and the elastic member is deformed. When the coil of the electromagnet is not input with current, the electromagnet has no magnetism, and the elastic member recovers the deformation. Under the elastic force of the elastic member, the elastic member drives the first limiting structure 50 to rotate along the second rotation direction to drive the first limiting structure 50 to disengage from the second limiting structure 60.

[0067] Alternatively, if Figures 1 to 5As shown, the elastic member includes a spring, a connecting hole 22 is provided on the swing arm 20, a second rotating shaft 52 is provided on the first limiting structure 50, and the second rotating shaft 52 is rotatably arranged in the connecting hole 22, the elastic member is sleeved on the second rotating shaft 52, one end of the elastic member is connected to the swing arm 20, and the other end of the elastic member is connected to the second rotating shaft 52 or the first limiting structure 50. The first limiting structure 50 can be in the shape of a plate, the first limiting structure 50 is provided with a second rotating shaft 52, and the second rotating shaft 52 can be respectively provided on the opposite two side edges of the first limiting structure 50, and the spring is sleeved on the second rotating shaft 52. When the coil of the electromagnet is input with current, the electromagnet drives the first limiting structure 50 to rotate along the first rotation direction through the magnetic force of the electromagnet, and the spring is deformed. When the coil of the electromagnet is not input with current, the spring recovers the deformation, and under the elastic force, the spring drives the first limiting structure 50 to rotate along the second rotation direction to drive the first limiting structure 50 to disengage from the second limiting structure 60. The first limiting structure 50 and the second rotating shaft 52 can be made of high-strength metal materials that are not easily deformed.

[0068] Optionally, the swing arm 20 is provided with a second rotating shaft 52, the first limiting structure 50 is provided with a connecting hole, the first limiting structure 50 is rotatably sleeved on the second rotating shaft 52, the first limiting structure 50 is rotatably sleeved on the second rotating shaft 52 through the connecting hole, the elastic member is sleeved on the second rotating shaft 52, one end of the elastic member is connected to the swing arm 20 or the second rotating shaft, and the other end of the elastic member is connected to the first limiting structure 50. When the coil of the electromagnet inputs current, the electromagnet drives the first limiting structure 50 to rotate along the first rotation direction, and the spring is deformed; when the coil of the electromagnet does not input current, the spring recovers the deformation, and under the elastic force, the spring drives the first limiting structure 50 to rotate along the second rotation direction to drive the first limiting structure 50 to disengage from the second limiting structure 60. The specific setting method of the driving structure of the swing arm 20 on the second housing 34 can be the same as the specific setting method of the driving structure of the swing arm 20 on the first housing 30, which will not be repeated here.

[0069] In some embodiments, the electronic device further comprises:

[0070] The detection module is used to detect the folding state of the electronic device.

[0071] The detection module is used to detect the folding state of the electronic device or the display screen. For example, the detection module can be used to detect the folding state of the first display screen 40. The first limiting structure 50 can be separated from the second limiting structure 60 or abutted against the second limiting structure 60 through the unfolding or folding state of the electronic device. When the electronic device is in the unfolded state, the first limiting structure 50 can be controlled to be separated from the second limiting structure 60, and the swing arm 20 and the first shell 30 can move relative to each other. When the electronic device is in the folded state, the first limiting structure 50 can be controlled to abut against the second limiting structure 60, and the swing arm 20 and the first shell 30 cannot move relative to each other. When the device falls to the ground, the shell is not easy to move, the display screen is not easy to slide, and the water drop area of ​​the display screen is not easy to be deformed and damaged.

[0072] In the embodiments of the present application, Figures 1 to 5 As shown, the electronic device also includes: a driving structure, the driving structure includes a first driving component 71 and a second driving component 72, the first driving component 71 includes a first magnetic part and a second magnetic part, the first magnetic part is arranged on the first limiting structure 50, the second magnetic part is arranged on the first shell 30, and at least one of the first magnetic part and the second magnetic part is an electromagnet. When the electronic device is in a folded state, when current is input into the coil of the electromagnet, the first magnetic part and the second magnetic part are attracted to rotate the first limiting structure 50 to abut against the second limiting structure 60 for limiting. For example, the second magnetic part can be an electromagnet. When the electronic device is in a folded state, when current is input into the coil of the electromagnet, the electromagnet has magnetism. Through the magnetic force of the electromagnet, the electromagnet can drive the first limiting structure 50 to rotate along the first rotation direction, so that the first driving component 71 drives the first limiting structure 50 to abut against the second limiting structure 60 for limiting.

[0073] The second driving assembly 72 includes an elastic member. When the coil of the electromagnet is powered off, the elastic member drives the first limiting structure 50 to rotate to separate from the second limiting structure 60 for resetting. The elastic member drives the first limiting structure 50 to rotate along the second rotation direction, so that the elastic member drives the first limiting structure 50 to disengage from the second limiting structure 60. When the coil of the electromagnet is powered off, that is, when no current is input to the coil of the electromagnet, the elastic member drives the first limiting structure 50 to rotate along the second rotation direction. When the coil of the electromagnet is input with current, the electromagnet has magnetism. Through the magnetic force of the electromagnet, the magnetic force of the electromagnet is greater than the force of the elastic member, and the electromagnet can drive the first limiting structure 50 to rotate along the first rotation direction, and the elastic member is deformed. When the coil of the electromagnet is not input with current, the electromagnet has no magnetism, and the elastic member recovers the deformation. Under the elastic force of the elastic member, the elastic member drives the first limiting structure 50 to rotate to separate from the second limiting structure 60 for resetting.

The detector can be used to detect the state of the first display screen 40 according to the light signal reflected by the first display screen 40 received by the receiver 42. The transmitter 41 and the receiver 42 can be located at the same end of the first display screen 40, and the transmitter 41 and the receiver 42 can be separated by a certain distance. When the first display screen 40 is unfolded, the light signal emitted by the transmitter 41 cannot be reflected by the first display screen 40, and the receiver 42 cannot receive the light signal reflected by the first display screen 40. The detector can detect that the state of the first display screen 40 is the unfolded state.

The detector can detect that the state of the first display screen 40 is the folded state.

[0076] Optionally, the electronic device further includes: a driving structure, the detection module is used to send a control signal when detecting that the electronic device or the first display screen 40 is in a folded state, and the driving structure receives the control signal to drive the first limiting structure 50 to move so as to abut against the second limiting structure 60. The driving structure may include an electromagnet, and the electromagnet may input current into the coil after receiving the control signal, and the first limiting structure 50 may be driven to rotate so as to abut against the second limiting structure 60 through the magnetic force of the electromagnet.

[0077] Alternatively, if Figure 1 to Figure 2 As shown, the electronic device also includes: a second display screen 80, which can be a non-flexible screen. The second display screen 80 can be arranged on the first shell 30 or the second shell 34, and the second display screen 80 can be arranged on the side of the first shell 30 or the second shell 34 away from the first display screen 40, so that when the first display screen 40 is in a folded state, it can be displayed through the second display screen 80, so that the user can use the second display screen 80.

[0078] like Figure 1 to Figure 2As shown, the electronic device also includes: a cover body 81, which can be a battery cover. The cover body 81 can be set on the first shell 30 or the second shell 34, and the cover body 81 can be set on the side of the first shell 30 or the second shell 34 away from the first display screen 40. A battery can be provided on the side of the cover body 81 close to the first shell 30 or the second shell 34, and the battery can be protected by the cover body 81.

[0079] like Figure 7 As shown, the electronic device also includes: a control module, which controls the input current to the coil of the electromagnet through the control module. The transmitter 41 may include an infrared light emitting diode (IR LED), and the receiver 42 may include an infrared photosensitive sensor. The control module may include a system-level chip (System onChip, SOC), a microcontroller unit (MCU), and a buck conversion circuit (Buck circuit).

The microcontroller unit can be electrically connected to the coil of the electromagnet through the serial peripheral interface, and the microcontroller unit can control the current input to the coil of the electromagnet.

[0080] The infrared light emitting diode can emit infrared light after receiving the system-level chip instruction, and the infrared light sensor can be used to receive infrared light. When the first display screen 40 is folded, the infrared light emitted by the infrared light emitting diode is reflected by the first display screen 40, and the infrared light sensor can receive the light signal reflected by the first display screen 40. The micro control unit can control the electromagnet according to the light signal reflected by the first display screen 40 received by the infrared light sensor. The infrared light sensor can also monitor the ambient light, and the display brightness of the display screen can be controlled by the ambient light. When the infrared light sensor detects that the first display screen 40 is in a fully folded state, the micro control unit can control the electromagnet to be powered on, and at this time, the first limiting structure 50 is rotated to a limited state by the suction force of the electromagnet. When the infrared light sensor detects that the mobile phone screen is not in a fully folded state, that is, the first display screen 40 is in the process of unfolding, the micro control unit can control the electromagnet to be powered off, and at this time, the first limiting structure 50 is subjected to the restoring elastic force of the spring, and the first limiting structure 50 is separated from the second limiting structure 60, and the first limiting structure 50 returns to the initial position that does not hinder the relative movement between the swing arm 20 and the first shell 30, so as to facilitate the folding or unfolding of the first display screen 40.

[0082] Detecting the folding state of the electronic device;

[0083] When it is detected that the electronic device is in the unfolded state, the first limiting structure 50 is controlled to be separated from the second limiting structure 60;

[0084] When it is detected that the electronic device is in the folded state, the first limiting structure 50 is controlled to abut against the second limiting structure 60 .

[0085] The folding or unfolding state of the electronic device is synchronized with that of the first display screen 40. When the electronic device or the first display screen 40 is detected to be in the unfolded state, the first limiting structure 50 is controlled to be separated from the second limiting structure 60 by the driving structure; when the electronic device or the first display screen 40 is detected to be in the folded state, the first limiting structure 50 is controlled to be abutted against the second limiting structure 60 by the driving structure. The driving structure includes a first driving component and a second driving component, the first driving component may include an electromagnet, and the second driving component includes an elastic member. When the electronic device or the first display screen 40 is detected to be in the folded state, current may be input into the coil of the electromagnet, and the electromagnet drives the first limiting structure 50 to abut against the second limiting structure 60; when the electronic device or the first display screen 40 is detected to be in the unfolded state, current input into the coil of the electromagnet is stopped, and the first limiting structure 50 may be driven to be separated from the second limiting structure 60 by the elastic member. When the electronic device or the first display screen 40 is in the folded state, the first limiting structure 50 abuts against the second limiting structure 60, and the swing arm 20 and the first housing 30 cannot move relative to each other. When the device falls to the ground and the rotating part 10 is impacted, since the first limiting structure 50 abuts against the second limiting structure 60, the swing arm 20 and the first shell 30 cannot move relative to each other, the first display screen 40 is not prone to sliding, and the water drop area of ​​the first display screen 40 is not prone to deformation and damage.
