[0004] Since the first shell is rotatably connected to the second shell, the first shell switches between a folded state and an unfolded state relative to the second shell. When the first shell is in a folded state relative to the second shell, that is, the electronic device is in a folded state, the user needs to manually unfold the electronic device so that the first shell is in an unfolded state relative to the second shell, that is, the electronic device is in an unfolded state. Summary of the invention

[0009] When the first shell is in a folded state relative to the second shell and there is a first magnetic force between the first magnetic component and the second magnetic component, the electrostrictive element drives the first magnetic component to rotate so that there is a second magnetic force between the first magnetic component and the second magnetic component, so that the first shell changes from a folded state to an unfolded state relative to the second shell.

[0010] In the embodiment of the present application, since the first shell is rotatably connected to the second shell, the first shell and the second shell can be close to each other or away from each other, so that the first shell switches between the folded state and the unfolded state relative to the second shell, so that the electronic device is folded or unfolded. Since the first magnetic component and the electrostrictive element are both arranged in the first shell, and the first end of the electrostrictive element is connected to the first magnetic component, and the second magnetic component is arranged in the second shell, therefore, when the first shell is in the folded state relative to the second shell, there is a first magnetic force between the first magnetic component and the second magnetic component, and the first magnetic component can be driven to rotate by the electrostrictive element, so that there is a second magnetic force between the second magnetic component and the first magnetic component, so that the first shell is separated from the second shell, that is, the first shell is changed from the folded state to the unfolded state relative to the second shell, that is, the electronic device is changed from the folded state to the unfolded state.

DETAILED DESCRIPTION

[0024] 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.

[0025] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0026] like Figures 1 to 11 As shown, the electronic device includes: a first shell 10 , a second shell 20 , a first magnetic component 40 , a second magnetic component 50 and an electrostrictive element 60 .

[0027] The first shell 10 is rotatably connected with the second shell 20 so that the first shell 10 switches between the folded state and the unfolded state relative to the second shell 20. The first magnetic component 40 and the electrostrictive element 60 are both arranged in the first shell 10, and the first end of the electrostrictive element 60 is connected with the first magnetic component assembly, the electrostrictive element 60 can drive the first magnetic component 40 to rotate, and the second magnetic component 50 is arranged in the second shell 20. When the first shell 10 is in the folded state relative to the second shell 20, and there is a first magnetic force between the first magnetic component 40 and the second magnetic component 50, the electrostrictive element 60 drives the first magnetic component 40 to rotate so that there is a second magnetic force between the first magnetic component 40 and the second magnetic component 50, so that the first shell 10 changes from the folded state to the unfolded state relative to the second shell 20.

[0028] In the embodiment of the present application, since the first shell 10 is rotatably connected to the second shell 20, the first shell 10 and the second shell 20 can be close to each other or away from each other, so that the first shell 10 switches between the folded state and the unfolded state relative to the second shell 20, so that the electronic device is folded or unfolded. Since the first magnetic component 40 and the electrostrictive element 60 are both arranged in the first shell 10, and the first end of the electrostrictive element 60 is connected to the first magnetic component 40, and the second magnetic component 50 is arranged in the second shell 20, therefore, when the first shell 10 is in the folded state relative to the second shell 20, there is a first magnetic force between the first magnetic component 40 and the second magnetic component 50, and the first magnetic component 40 can be driven by the electrostrictive element 60 to rotate, so that there is a second magnetic force between the second magnetic component 50 and the first magnetic component 40, so that the first shell 10 is separated from the second shell 20, that is, the first shell 10 is changed from the folded state to the unfolded state relative to the second shell 20, that is, the electronic device is changed from the folded state to the unfolded state. That is, in the embodiment of the present application, by arranging the first magnetic component 40 and the electrostrictive element 60 in the first shell 10, and the electrostrictive element 60 is connected to the first magnetic component 40, and the second magnetic component 50 is arranged in the second shell 20, so that when the first shell 10 is in a folded state relative to the second shell 20, the electrostrictive element 60 can drive the first magnetic component 40 to rotate, so that there is a second magnetic force between the magnetic poles of the second magnetic component 50 and the first magnetic component 40, so that the first shell 10 is changed from the folded state to the unfolded state relative to the second shell 20, avoiding the user to manually unfold the electronic device.

[0029] It should be noted that, in the embodiment of the present application, the second end of the electrostrictive element 60 can be fixed in the first housing 10. In addition, the electronic device may further include a flexible screen 30, which is connected to the first housing 10 and the second housing 20, respectively, so that when the first housing 10 is folded or unfolded relative to the second housing 20, the flexible screen 10 can be folded or unfolded.

[0030] In addition, in the embodiment of the present application, the flexible screen 30 can be connected to the first shell 10 and the second shell 20 respectively by bonding, that is, the flexible screen 30 is bonded to the first shell 10 and the second shell 20 respectively. Among them, the flexible screen 30 can be bonded to the first shell 10 and the second shell 20 by bonding, such as optical glue, double-sided tape, etc.

[0031] In addition, in the embodiment of the present application, when the first shell 10 is in a folded state relative to the second shell 20, at this time, the first magnetic component 40 and the second magnetic component 50 can be positioned relative to each other, and there is a first magnetic force between the first magnetic component 40 and the second magnetic component 60. Thereafter, the electrostrictive element 60 can drive the first magnetic component 40 to rotate, so that there is a second magnetic force between the first magnetic component 40 and the second magnetic component 60.

[0032] In addition, in the embodiment of the present application, the first magnetic force is different from the second magnetic force, and the first magnetic force may be an attractive force, that is, the magnetic poles of the first magnetic component 40 and the magnetic poles of the second magnetic component 50 are opposite, and there is an attractive force between the first magnetic component 40 and the second magnetic component 50. The second magnetic force may be a repulsive force, that is, the magnetic poles of the first magnetic component 40 and the magnetic poles of the second magnetic component 50 are the same, and there is a repulsive force between the first magnetic component 40 and the second magnetic component 50.

[0033] For example, Figure 2 As shown, the first magnetic component 40 has an N pole and an S pole, and the second magnetic component 50 has an N pole and an S pole. When the first housing 10 is in a folded state relative to the second housing 20, that is, when the electronic device is in a folded state, the first magnetic component 40 and the second magnetic component 50 are positioned opposite to each other, the N pole of the first magnetic component 40 faces the S pole of the second magnetic component 50, and there is an attraction between the first magnetic component 40 and the second magnetic component 50. When the electronic device needs to be unfolded, the electrostrictive element 60 is energized to drive the first magnetic component 40 to rotate, so that the S pole of the first magnetic component 40 faces the S pole of the second magnetic component 50, so that there is a repulsion between the first magnetic component 40 and the second magnetic component 50, and the electronic device is unfolded.

[0034] In addition, in the embodiment of the present application, the first shell 10 and the second shell 20 are rotatably connected via a rotating shaft. That is, a connecting arm may be provided on the first shell 10, and a connecting arm may also be provided on the second shell 20, and both the connecting arm of the first shell 10 and the connecting arm of the second shell 20 may be connected to the rotating shaft, so that the first shell 10 and the second shell 20 can be rotatably connected via the rotating shaft, and the first shell 10 and the second shell 20 can rotate relative to each other.

[0035] In addition, in the embodiment of the present application, when the electrostrictive element 60 is powered on and shortened, the electronic device changes from the folded state to the unfolded state. After the electronic device is unfolded, the electrostrictive element 60 can be powered off, that is, the electrostrictive element 60 is no longer powered.

[0036] In addition, in the embodiment of the present application, the electrostrictive element 60 may be connected to the first magnetic component 40 in different ways.

[0037] In some embodiments, Figure 3 or Figure 5 As shown, the first magnetic component 40 can be connected to a first connecting column 41, a first insulating rope 42 is wound around the first connecting column 41, one end of the first insulating rope 42 is fixed to the first connecting column 41, and the other end of the first insulating rope 42 is connected to the first end of the electrostrictive element 60. When the electrostrictive element 60 is energized and shortened, the electrostrictive element 60 drives the first connecting column 41 to rotate through the first insulating rope 42, so that the first magnetic component 40 rotates.

[0038] Since the first magnetic component 40 is connected to the first connecting column 41, the first insulating rope 42 is wound around the first connecting column 41, and one end of the first insulating rope 42 is fixed on the first connecting column 41, therefore, when the first insulating rope 42 is pulled by applying force to the other end of the first insulating rope 42, the first connecting column 41 will be rotated, so that the first connecting column 41 drives the first magnetic component 40 to rotate. Since the other end of the first insulating rope 42 is connected to the first end of the electrostrictive element 60, and the second end of the electrostrictive element 60 is fixed in the first housing 10, therefore, when the electrostrictive element 60 is energized and shortened, the second end of the electrostrictive element 60 remains stationary, and the first end of the electrostrictive element 60 applies a pulling force to the first insulating rope 42, so that the first insulating rope 42 drives the first connecting column 41 to rotate, so that the first connecting column 41 drives the first magnetic component 40 to rotate, so that the first magnetic component 40 and the second magnetic component 50 are the second magnetic force, so that the electronic device is turned on.

[0039] It should be noted that, by providing the first insulating rope 42, when the electrostrictive element 60 is energized, the electric energy will not be transferred to the first insulating rope 42, thereby avoiding the problem of the first insulating rope 42 being conductive and causing leakage in the electronic device. In addition, the material of the first insulating rope 42 can be an insulating material such as nylon and spandex. The first end of the first insulating rope 42 can be fixed to the first connecting column 41 by bonding. Of course, other methods can also be used. For example, a mounting hole is provided on the first connecting column 41, and the first end of the first insulating rope 42 is tied in the mounting hole so that the first end of the first insulating rope 42 is fixed to the first connecting column 41. The embodiment of the present application does not limit the method for fixing the first end of the first insulating rope 42 to the first connecting column 41.

[0040] In addition, in some embodiments, Figure 4 As shown, the electronic device may further include a first reset torsion spring 43. The first reset torsion spring 43 is sleeved on the first connecting column 41, a first receiving groove 401 is provided on the first magnetic component 40, a first end of the first reset torsion spring 43 is located in the first receiving groove 401, and a second end of the first reset torsion spring 43 is fixed in the first housing 10.

[0041] When the first reset torsion spring 43 is sleeved on the first connecting column 41, the first end of the first reset torsion spring 43 is located in the first accommodating groove 401, and the second end of the first reset torsion spring 43 is fixed in the first housing 10, at this time, when the electrostrictive element 60 is energized and shortened, the first insulating rope 42 on the first connecting column 41 is subjected to the pulling force of the electrostrictive element 60, so that when the first connecting column 41 rotates, the first connecting column 41 will drive the first magnetic component 40 to rotate, so that the groove wall of the first accommodating groove 401 on the first magnetic component 40 will drive the first end of the first reset torsion spring 43 to move.

[0042] Since the second end of the first reset torsion spring 43 is fixed in the first housing 10, when the first end of the first reset torsion spring 43 moves with the groove wall of the first accommodating groove 401, the first reset torsion spring 43 is subjected to force, that is, the first reset torsion spring 43 can be compressed or stretched, so that the electronic device changes from a folded state to an unfolded state. Afterwards, when the electrostrictive element 60 is powered off, the electrostrictive element 60 stops applying force to the first insulating rope 42, so that the first insulating rope 42 stops applying force to the first connecting column 41, so that the first magnetic component 40 stops applying force to the first reset torsion spring 43, so that the first reset torsion spring 43 will return to the initial state, that is, the first end of the first reset torsion spring 43 will apply force to the first magnetic component 40, so that the first magnetic component 40 rotates in the opposite direction, that is, the rotation direction of the first magnetic component 40 under the action of the first reset torsion spring 43 is opposite to the rotation direction under the action of the first connecting column 41. Thus, the first reset torsion spring 43 will drive the first magnetic component 40 to return to the initial state, so that there is a first magnetic force between the first magnetic component 40 and the second magnetic component 50. However, since the electronic device has been unfolded, the distance between the first magnetic component 40 and the second magnetic component 50 is relatively large, and even if there is a first magnetic force between the first magnetic component 40 and the second magnetic component 50, the electronic device will not change from the unfolded state to the folded state under the action of the first magnetic force. When the first magnetic component 40 rotates in the opposite direction under the action of the first reset torsion spring 43, the first magnetic component 40 drives the first connecting column 41 to rotate in the opposite direction, so that the first connecting column 41 drives the first insulating rope 42 to move, and the first insulating rope 42 drives the electrostrictive element 60 to move, so that the electrostrictive element 60 returns to the initial state.

[0043] That is, by providing the first return torsion spring 43, when the electronic device is unfolded and the electrostrictive element 60 is powered off, the first return torsion spring 43 can restore the first magnetic component 40 and the electrostrictive element 60 to their initial states, thereby facilitating the unfolding of the electronic device by energizing the electrostrictive element 60 after the electronic device is folded.

[0044] For example, when the electronic device needs to be unfolded, the electrostrictive element 60 is powered, the electrostrictive element 60 is shortened, the electrostrictive element 60 drives the first insulating rope 42 to make the first connecting column 41 rotate clockwise, so that the first magnetic component 40 rotates clockwise, and there is a second magnetic force between the first magnetic component 40 and the second magnetic component 50, and in the process of the first magnetic component 40 rotating clockwise, the first magnetic component 40 applies force to the first reset torsion spring 43, so that the first reset torsion spring 43 stretches or contracts. After the electronic device is unfolded, the electrostrictive element 60 is powered off, at which time, the electrostrictive element 60 stops applying force to the first insulating rope 42, the first reset torsion spring 43 returns to the initial state, the first reset torsion spring 43 drives the first magnetic component 40 to rotate counterclockwise, so that the first magnetic component 40 returns to the initial state, so that the first magnetic component 40 drives the first connecting column 41 to rotate counterclockwise, and the first connecting column 41 applies force to the electrostrictive element 60 through the first insulating rope 42, so that the electrostrictive element 60 returns to the initial state.

[0045] It should be noted that, in the embodiment of the present application, the first magnetic component 40 can be connected to the first connecting column 41 at the opposite ends, so that the first return torsion spring 43 can be sleeved on the two first connecting columns 41. At this time, the two first return torsion springs 43 can apply force to the first magnetic component 40, so that the first magnetic component 40 can be quickly restored to the initial state under the action of the two first return torsion springs 43, so that the electrostrictive element 60 can be quickly restored to the initial state. Of course, one end of the first magnetic component 40 can be connected to the first connecting column 41. At this time, the first return torsion spring 43 can be sleeved on the first connecting column 41, and the first return torsion spring 43 can also apply force to the first magnetic component 40, so that the first magnetic component 40 is restored to the initial state. In this regard, the embodiment of the present application is not limited here.

[0046] In addition, in the embodiments of the present application, Figure 4 or Figure 6 As shown, the width of the first accommodating groove 401 is greater than the width of the first end of the first return torsion spring 43 , and the width of the first accommodating groove 401 is the distance between two opposite groove walls of the first accommodating groove 401 .

[0047] Since the width of the first accommodating groove 401 is greater than the width of the first end of the first return torsion spring 43, when the first magnetic component 40 rotates driven by the first connecting column 41, the first magnetic component 40 will rotate first. After the first magnetic component 40 rotates a certain angle, the groove wall of the first accommodating groove 401 on the first magnetic component 40 will contact the first end of the first return torsion spring 43, thereby applying force to the first end of the first return torsion spring 43, so that the first end of the first return torsion spring 43 moves with the first magnetic component 40. That is, by setting the width of the first accommodating groove 401 to be larger than the width of the first end of the first return torsion spring 43, a gap is provided between the first end of the first return torsion spring 43 and the groove wall of the first accommodating groove 401, so that when the first magnetic component 40 rotates, the first magnetic component 40 does not directly drive the first end of the first return torsion spring 43 to move, thereby avoiding the maximum force that simultaneously drives the first magnetic component 40 and the first return torsion spring 43 to move, reducing the initial force required to rotate the first magnetic component 40, thereby facilitating the electrostrictive element 60 to rotate the first magnetic component 40 when the power is on and shortened.

[0048] In addition, since the width of the first accommodating groove 401 is greater than the width of the first end of the first return torsion spring 43 , it is also convenient to assemble the first return torsion spring 43 , that is, to install the first end of the first return torsion spring 43 on the first magnetic component 40 .

[0049] In addition, in some embodiments, the electronic device may include a first connecting column 41 and a first reset torsion spring 43, the first connecting column 41 is not connected to the first magnetic component 40, the first reset torsion spring 43 is sleeved on the first connecting column 41, and the first reset torsion spring 43 and the first connecting column 41 are interference fit, the first magnetic component 40 is provided with a first receiving groove 401, the first end of the first reset torsion spring 43 is located in the first receiving groove 401, and the second end of the first reset torsion spring 43 is fixed in the first housing 10. A first insulating rope 42 is wound around the first connecting column 41, one end of the first insulating rope 42 is fixed to the first connecting column 41, and the other end of the first insulating rope 42 is connected to the first end of the electrostrictive element 60. At this time, when the electrostrictive element 60 is energized and shortened, the first end of the electrostrictive element 60 applies a pulling force to the first insulating rope 42, so that the first insulating rope 42 drives the first connecting column 41 to rotate, and the first connecting column 41 drives the first return torsion spring 43 to rotate. After the rotation, the first return torsion spring 43 drives the groove wall of the first accommodating groove 401, so that the first magnetic component 40 rotates.

[0050] The number of the first connecting column 41 can be one, the number of the first reset torsion springs 43 can be two, the first connecting column 41 is located at one end of the first magnetic component 40, a first reset torsion spring 43 is sleeved on the first connecting column 41, and the first reset torsion spring 43 is interference fit with the first connecting column 41, and the first magnetic component 40 is provided with two first receiving grooves 401, the two first receiving grooves 401 are respectively opposite to the two ends of the first magnetic component 40, the first ends of the two first reset torsion springs 43 are respectively located in the two first receiving grooves 401, and the second ends of the two first reset torsion springs 43 are respectively fixed in the first housing 10. At this time, by providing two first reset torsion springs 43, when the first connecting column 41 rotates, the first reset torsion spring 43 sleeved on the first connecting column 41 drives the first magnetic component 40 to rotate, and the first magnetic component 40 drives the first end of the other torsion spring to move, so that the other torsion spring is subjected to torsion. When the first connecting post 41 stops rotating, at this time, another torsion spring drives the first magnetic component 40 to reset, and the first magnetic component 40 resets the first connecting post 41 through the first reset torsion spring 43 sleeved on the first connecting post 41 .

[0051] In addition, in some embodiments, the electronic device may include a first reset torsion spring 43 and a first connecting column 41, the first connecting column 41 is connected to the first magnetic component 40, the first end of the first reset torsion spring 43 is located in the first receiving groove 401 of the first magnetic component 40, and the second end of the first reset torsion spring 43 is fixed in the first housing 10, that is, the first reset torsion spring 43 is not sleeved on the first connecting column 41. At this time, when the first magnetic component 40 rotates driven by the first connecting column 41, the first magnetic component 40 can drive the first end of the first reset torsion spring 43 to move, so that the first reset torsion spring 43 is subjected to torsion, so that when the first connecting column 41 stops rotating, that is, when the first magnetic component 40 stops rotating, the first end of the first reset torsion spring 43 can drive the first magnetic component 40 to rotate, so that the first magnetic component 40 is reset.

[0052] In some embodiments, Figure 7 or Fig. 9 As shown, the electronic device may further include a gear assembly 45, the first magnetic assembly 40 may be connected to a second connecting column 44, the second connecting column 44 is connected to one end of the gear assembly 45, the other end of the gear assembly 45 is connected to a rotating column 46, a second insulating rope 47 is wound around the rotating column 46, one end of the second insulating rope 47 is fixed on the rotating column 46, and the other end of the second insulating rope 47 is connected to the first end of the electrostrictive element 60. When the electrostrictive element 60 is energized and shortened, the electrostrictive element 60 drives the rotating column 46 to rotate through the second insulating rope 47, so that the gear assembly 45 rotates, and the gear assembly 45 drives the second connecting column 44 to rotate, so that the first magnetic assembly 40 rotates.

[0053] Since a second connecting column 44 is provided at one end of the first magnetic component 40, the second connecting column 44 is connected to one end of the gear component 45, and the other end of the gear component 45 is connected to a rotating column 46, a second insulating rope 47 is wound around the rotating column 46, and one end of the second insulating rope 47 is fixed on the rotating column 46. Therefore, when force is applied to the other end of the second insulating rope 47 to pull the second insulating rope 47, the rotating column 46 will rotate, and the rotating column 46 will drive the gear component 45 to rotate, and the gear component 45 will drive the second connecting column 44 to rotate, so that the second connecting column 44 drives the first magnetic component 40 to rotate. Since the other end of the second insulating rope 47 is connected to the first end of the electrostrictive element 60, the second end of the electrostrictive element 60 is fixed in the first housing 10. Therefore, when the electrostrictive element 60 is energized and shortened, the second end of the electrostrictive element 60 remains stationary, and the first end of the electrostrictive element 60 applies a pulling force to the second insulating rope 47, so that the second insulating rope 47 drives the rotating column 46 to rotate, thereby the rotating column 46 drives the gear assembly 45 to rotate, and the gear assembly 45 drives the second connecting column 44 to rotate, thereby the second connecting column 44 drives the first magnetic component 40 to rotate, so that the first magnetic component 40 and the second magnetic component 50 are the second magnetic force, so that the electronic device is turned on.

[0054] It should be noted that, by providing the second insulating rope 47, when the electrostrictive element 60 is energized, the electric energy will not be transferred to the second insulating rope 47, thereby preventing the second insulating rope 47 from conducting electricity and causing leakage in the electronic device. In addition, the material of the second insulating rope 47 can be an insulating material such as nylon and spandex. The first end of the second insulating rope 47 can be fixed to the rotating column 46 by bonding. Of course, other methods can also be used. For example, a mounting hole is provided on the rotating column 46, and the first end of the second insulating rope 47 is tied in the mounting hole, so that the first end of the second insulating rope 47 is fixed to the second connecting column 44. The method of fixing the first end of the second insulating rope 47 to the rotating column 46 is not limited in the embodiment of the present application.

[0055] In addition, in the embodiments of the present application, Figure 8 As shown, the electronic device may further include a second reset torsion spring 48. The second reset torsion spring 48 is sleeved on the second connecting column 44, a second receiving groove 402 is provided on the first magnetic component 40, a first end of the second reset torsion spring 48 is located in the second receiving groove 402, and a second end of the second reset torsion spring 48 is fixed in the first housing 10.

[0056] When the second reset torsion spring 48 is sleeved on the second connecting column 44, the first end of the second reset torsion spring 48 is located in the second accommodating groove 402, and the second end of the second reset torsion spring 48 is fixed in the first housing 10, at this time, when the electrostrictive element 60 is energized and shortened, the second insulating rope 47 on the rotating column 46 is subjected to the pulling force of the electrostrictive element 60, so that when the rotating column 46 rotates, the rotating column 46 drives the gear assembly 45 to rotate, and when the gear assembly 45 drives the second connecting column 44 to rotate, the second connecting column 44 drives the first magnetic component 40 to rotate, so that the groove wall of the second accommodating groove 402 on the first magnetic component 40 drives the first end of the second reset torsion spring 48 to move.

[0057] Since the second end of the second reset torsion spring 48 is fixed in the first housing 10, when the first end of the second reset torsion spring 48 moves along with the groove wall of the second accommodating groove 402, the second reset torsion spring 48 is subjected to force, that is, the first reset torsion spring 43 can be compressed or stretched, so that the electronic device changes from a folded state to an unfolded state. Afterwards, when the electrostrictive element 60 is powered off, the electrostrictive element 60 stops applying force to the second insulating rope 47, so that the second insulating rope 47 stops applying force to the rotating column 46, the rotating column 46 stops applying force to the gear assembly 45, and the gear assembly 45 stops applying force to the second connecting column 44, so that the first magnetic component 40 stops applying force to the second reset torsion spring 48, so that the second reset torsion spring 48 will return to the initial state, that is, the first end of the second reset torsion spring 48 will apply force to the first magnetic component 40, so that the first magnetic component 40 rotates in the opposite direction, that is, the rotation direction of the first magnetic component 40 under the action of the second reset torsion spring 48 is opposite to the rotation direction under the action of the second connecting column 44. Thus, the second reset torsion spring 48 will drive the first magnetic component 40 to return to the initial state, so that there is a first magnetic force between the first magnetic component 40 and the second magnetic component 50. However, since the electronic device has been unfolded, the distance between the first magnetic component 40 and the second magnetic component 50 is large. Even if there is a first magnetic force between the first magnetic component 40 and the second magnetic component 50, the electronic device will not change from the unfolded state to the folded state under the action of the first magnetic force. When the first magnetic component 40 rotates in the opposite direction under the action of the second reset torsion spring 48, at this time, the first magnetic component 40 drives the second connecting column 44 to rotate in the opposite direction, so that the second connecting column 44 drives the gear component 45 to rotate in the opposite direction, so that the gear component 45 drives the rotating column 46 to rotate, the rotating column 46 drives the second insulating rope 47 to move, and the second insulating rope 47 drives the electrostrictive element 60 to move, so that the electrostrictive element 60 returns to the initial state.

[0058] That is, by providing the second reset torsion spring 48, when the electronic device is unfolded and the electrostrictive element 60 is powered off, the second reset torsion spring 48 can restore the first magnetic component 40 and the electrostrictive element 60 to their initial states, thereby facilitating the unfolding of the electronic device by energizing the electrostrictive element 60 after the electronic device is folded.

[0059] For example, when the electronic device needs to be unfolded, the electrostrictive element 60 is energized, the electrostrictive element 60 is shortened, the electrostrictive element 60 drives the second insulating rope 47 to make the rotating column 46 rotate clockwise, the rotating column 46 drives the gear assembly 45 to rotate, the gear assembly 45 drives the second connecting wheel to rotate clockwise, so that the first magnetic component 40 rotates clockwise, there is a second magnetic force between the first magnetic component 40 and the second magnetic component 50, and in the process of the first magnetic component 40 rotating clockwise, the first magnetic component 40 applies force to the second reset torsion spring 48, so that the second reset torsion spring 48 stretches or contracts. After the electronic device is unfolded, the power supply to the electrostrictive element 60 is stopped. At this time, the electrostrictive element 60 stops applying force to the second insulating rope 47, and the second reset torsion spring 48 returns to its initial state. The second reset torsion spring 48 drives the first magnetic component 40 to rotate counterclockwise, so that the first magnetic component 40 returns to its initial state, so that the first magnetic component 40 drives the second connecting column 44 to rotate counterclockwise, and the second connecting column 44 drives the gear assembly 45 to rotate, so that the rotating column 46 rotates counterclockwise, and the rotating column 46 applies force to the electrostrictive element 60 through the second insulating rope 47, so that the electrostrictive element 60 returns to its initial state.

[0060] It should be noted that, in the embodiment of the present application, the two opposite ends of the first magnetic component 40 can be connected to the second connecting column 44 respectively, so that the two second connecting columns 44 can be sleeved with a second reset torsion spring 48, at this time, the two second reset torsion springs 48 can apply force to the first magnetic component 40, so that the first magnetic component 40 can be quickly restored to the initial state under the action of the two second reset torsion springs 48, so that the electrostrictive element 60 can be quickly restored to the initial state. Of course, one end of the first magnetic component 40 can be connected to the second connecting column 44, at this time, the second reset torsion spring 48 can be sleeved on the second connecting column 44, and the second reset torsion spring 48 can also apply force to the first magnetic component 40, so that the first magnetic component 40 is restored to the initial state. In this regard, the embodiment of the present application is not limited here.

[0061] In addition, in the embodiments of the present application, Figure 8 or Fig.10 As shown, the width of the second accommodating groove 402 is greater than the width of the first end of the second return torsion spring 48 , and the width of the second accommodating groove 402 is the distance between two opposite groove walls of the second accommodating groove 402 .

[0062] Since the width of the second accommodating groove 402 is greater than the width of the first end of the second return torsion spring 48, when the first magnetic component 40 rotates driven by the second connecting column 44, the first magnetic component 40 will rotate first. After the first magnetic component 40 rotates a certain angle, the groove wall of the second accommodating groove 402 on the first magnetic component 40 will contact the first end of the second return torsion spring 48, thereby applying force to the first end of the second return torsion spring 48, so that the first end of the second return torsion spring 48 moves with the first magnetic component 40. That is, by setting the width of the second accommodating groove 402 to be greater than the width of the first end of the second return torsion spring 48, a gap is provided between the first end of the second return torsion spring 48 and the groove wall of the second accommodating groove 402, so that when the first magnetic component 40 rotates, the first magnetic component 40 does not directly drive the first end of the second return torsion spring 48 to move, thereby avoiding the maximum force that simultaneously drives the first magnetic component 40 and the second return torsion spring 48 to move, reducing the initial force required to rotate the first magnetic component 40, thereby facilitating the electrostrictive element 60 to rotate the first magnetic component 40 when the power is on and shortened.

[0063] In addition, since the width of the second accommodating groove 402 is greater than the width of the first end of the second return torsion spring 48 , it is also convenient to assemble the second return torsion spring 48 , that is, to install the first end of the second return torsion spring 48 on the first magnetic component 40 .

[0064] In addition, in the embodiments of the present application, Figure 7 As shown, the gear assembly 45 may include a first gear 451 and a second gear 452. The first gear 451 is connected to the second connecting column 44, the first gear 451 is meshed with the second gear 452, and the second gear 452 is connected to the rotating column 46.

[0065] Since the first gear 451 is connected to the second connecting column 44, the first gear 451 is meshed with the second gear 452, and the second gear 452 is connected to the rotating column 46, when the electronic device needs to be unfolded, that is, the electrostrictive element 60 drives the second insulating rope 47 on the rotating column 46 to be subjected to force so that the rotating column 46 rotates, the rotating column 46 drives the second gear 452 to rotate, so that the second gear 452 drives the first gear 451 to rotate, and the first gear 451 drives the second connecting column 44 to rotate, thereby driving the first magnetic component 40 to rotate. When the second reset torsion spring 48 drives the first magnetic component 40 to return to the initial state, the first magnetic component 40 drives the second connecting column 44 to rotate, the second connecting column 44 drives the first gear 451 to rotate, the first gear 451 drives the second gear 452 to rotate, and the second gear 452 drives the rotating column 46 to rotate, so that the second insulating rope 47 on the rotating column 46 applies force to the electrostrictive element 60, so that the electrostrictive element 60 returns to the initial state. That is, by providing the first gear 451 and the second gear 452 , the electrostrictive element 60 can drive the second insulating rope 47 to shorten it by electrifying the electrostrictive element 60 , thereby rotating the first magnetic component 40 and unfolding the electronic device.

[0066] It should be noted that the first gear 451 and the second gear 452 can both be bevel gears. Of course, the first gear 451 and the second gear 452 can also be other types, for example, the first gear 451 and the second gear 452 can also be spur gears. The embodiment of the present application does not limit the types of the first gear 451 and the second gear 452. In addition, when the gear assembly 45 includes the first gear 451 and the second gear 452, at this time, the first gear 451 can be one end of the gear assembly 45, and the second gear 452 can be the other end of the gear assembly 45.

[0067] In addition, the gear assembly 45 may also include three gears, that is, the gear assembly 45 includes a first gear 451, a second gear 452 and a third gear, the third gear is meshed with the first gear 451 and the second gear 452 respectively, the first gear 451 is connected to the second connecting column 44, and the second gear 452 is connected to the rotating column 46. At this time, when the first gear 451 rotates, the first gear 451 drives the third gear to rotate, and the third gear drives the second gear 452 to rotate. The number of gears in the gear assembly 45 is not limited in the embodiment of the present application.

[0068] In addition, in some embodiments, Fig.11As shown, the electronic device may further include an angle detection member 70 and a controller (not shown in the figure). The controller is located in the first housing 10 or the second housing 20, and the angle detection member 70 is connected to the first housing 10 and the second housing 20 respectively, and the angle detection member 70 is electrically connected to the controller. The angle detection member 70 is used to detect the angle value between the first housing 10 and the second housing 20, and send the angle value to the controller. The controller is used to control the electrostrictive member 60 to power off when the angle value is greater than or equal to a preset angle threshold.

[0069] When the angle detection member 70 is connected to the first shell 10 and the second shell 20 respectively, and the angle detection member 70 is electrically connected to the control, at this time, when the first shell 10 is unfolded relative to the second shell 20, that is, when the electronic device is unfolded, the angle detection member 70 can detect the angle between the first shell 10 and the second shell 20 in real time, and send the angle value to the controller. After the controller receives the angle value, the controller will compare the angle value with the preset angle threshold value. When the angle value is greater than or equal to the angle threshold value, it indicates that the electronic device is already in the unfolded state, and there is no need to power the electrostrictive member 60, so that the controller can control the electrostrictive member 60 to be powered off. That is, by setting the angle detection member 70, it is possible to stop powering the electrostrictive member 60 after the electronic device is unfolded, and the electric energy of the electronic device can be saved.

[0070] It should be noted that the preset angle threshold can be set according to actual needs, for example, the preset angle threshold can be 90 degrees or 120 degrees. The specific value of the preset angle threshold is not limited in the embodiment of the present application.

[0071] In addition, in some embodiments, Fig. 9 As shown, the electronic device may further include a wire 80 and a power supply (not shown). The power supply is located in the first housing 10 or the second housing 20, one end of the wire 80 is electrically connected to the power supply, and the other end of the wire 80 is connected to the electrostrictive element 60, and the power supply is used to supply power to the electrostrictive element 60 through the wire 80.

[0072] When one end of the wire 80 is electrically connected to the power supply, and the other end of the wire 80 is connected to the electrostrictive element 60, the power supply can supply power to the electrostrictive element 60 through the wire 80, thereby shortening the electrostrictive element 60 and expanding the electronic device. That is, by providing the wire 80 and the power supply, it is convenient to supply power to the electrostrictive element 60.

[0073] It should be noted that when the electronic device includes a controller, the power supply can be electrically connected to the controller, and the controller can control the power supply to supply power to the electrostrictive element 60 , or the controller can control the power supply to stop supplying power to the electrostrictive element 60 .

[0074] In addition, in the embodiments of the present application, Fig.11 As shown, a control button 101 is disposed on the first housing 10 or the second housing 20. The control button 101 is electrically connected to the power source, and the control button 101 is used to control the power source to supply power to the electrostrictive element 60.

[0075] Since the control case is electrically connected to the power source, when the electronic device needs to be unfolded, the control button 101 can be pressed, so that the control button 101 can control the power source to supply power to the electrostrictive element 60, so that the electrostrictive element 60 is energized and shortened, thereby unfolding the electronic device. That is, by providing the control button 101, it is easy to control the unfolding of the electronic device.

[0076] It should be noted that, in the embodiment of the present application, the electrostrictive element 60 can be a memory alloy wire, or a linear structure made of piezoelectric ceramics. Of course, the electrostrictive element 60 can also be made of other electrostrictive materials, which is not limited in the embodiment of the present application. In addition, in the embodiment of the present application, the electronic device can include but is not limited to a mobile phone, a laptop computer, etc.

[0077] In the embodiment of the present application, since the first shell 10 is rotatably connected to the second shell 20, the first shell 10 and the second shell 20 can be close to each other or away from each other, so that the first shell 10 switches between the folded state and the unfolded state relative to the second shell 20, so that the electronic device is folded or unfolded. Since the first magnetic component 40 and the electrostrictive element 60 are both arranged in the first shell 10, and the first end of the electrostrictive element 60 is connected to the first magnetic component 40, and the second magnetic component 50 is arranged in the second shell 20, therefore, when the first shell 10 is in the folded state relative to the second shell 20, there is a first magnetic force between the first magnetic component 40 and the second magnetic component 50, and the first magnetic component 40 can be driven by the electrostrictive element 60 to rotate, so that there is a second magnetic force between the second magnetic component 50 and the first magnetic component 40, so that the first shell 10 is separated from the second shell 20, that is, the first shell 10 is changed from the folded state to the unfolded state relative to the second shell 20, that is, the electronic device is changed from the folded state to the unfolded state. That is, in the embodiment of the present application, by arranging the first magnetic component 40 and the electrostrictive element 60 in the first shell 10, and the electrostrictive element 60 is connected to the first magnetic component 40, and the second magnetic component 50 is arranged in the second shell 20, so that when the first shell 10 is in a folded state relative to the second shell 20, the electrostrictive element 60 can drive the first magnetic component 40 to rotate, so that there is a second magnetic force between the magnetic poles of the second magnetic component 50 and the first magnetic component 40, so that the first shell 10 is changed from the folded state to the unfolded state relative to the second shell 20, avoiding the user to manually unfold the electronic device.

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