[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Reference Figures 1 to 3 , shows a schematic structural diagram of an electronic device according to an embodiment of the present application, which may specifically include: a first body 100 and a second body 200, wherein the first body 100 and the second body 200 are rotatably connected to realize switching between a folded state and an unfolded state;

[0025] The first body 100 is provided with an electrodeformable element 130 , a first rotating element 120 and a first magnetic element 110 , and the second body 200 is provided with a second magnetic element 210 ;

[0026] The first magnetic member 110 includes at least two magnets 111, which are sequentially arranged in the circumference of the first rotating member 120 and connected to the first rotating member 120, and the magnetism of two adjacent magnets 111 is opposite;

[0027] The electrodeformable element 130 can switch between an initial shape and a memory shape to drive the first rotating element 120 to rotate. When it is necessary to switch from the folded state to the unfolded state, the electrodeformable element 130 can switch from the initial state to the memory state to drive the first rotating element 120 to rotate until the target magnet 112 of at least two magnets 111 and the second magnetic element 210 repel each other.

[0028] In an embodiment of the present invention, the first body 100 of the electronic device is rotatably connected to the second body 200 to achieve switching between a folded state and an unfolded state. When the electronic device is in the folded state, the electrodeformable member 130 drives the pusher 122 to move in translation, and the pusher 122 drives the first rotating member 120 to rotate in the first body 100 until the target magnet 112 on the first rotating member 120 and the second magnetic member 210 are in relative positions to generate mutually repelling magnetic forces, so that the electronic device can be easily switched from the folded state to the unfolded state. It avoids the user frequently opening the folding screen and starting the motor multiple times to consume the power of the electronic device, thereby increasing the battery life of the electronic device. And there is no need to use a large-sized motor to increase the overall thickness of the electronic device, which is conducive to reducing the size of the electronic device. There is also no large operating noise, which improves the user experience.

[0029] Specifically, the first body 100 and the second body 200 can serve as the structural main body of the electronic device. The first body 100 and the second body 200 can be rotatably connected by a hinge to achieve switching between an unfolded state and a folded state. When the electronic device needs to be used, the electronic device can be unfolded to achieve a larger display area. After the electronic device is used, the electronic device can be switched to the folded state to make the electronic device smaller and easier to carry.

[0030] Optionally, the electrodeformable member 130 includes a memory alloy member. When the memory alloy member is powered on, it is instantly heated and contracted to switch to the memory shape. The memory alloy member can generate a certain displacement through the deformation amount, providing a power source for the movement of the push member 122. In addition, the memory alloy member can provide a reliable large pulling force and no operating noise is generated, which improves the user experience. When the memory alloy member is powered off, its temperature drops and reverse deformation occurs again, returning to the initial shape, driving the push member 122 to reset.

[0031] For example, the memory alloy piece can be set as a memory alloy wire with a linear structure. After the memory alloy wire is powered and heated to a preset temperature, the memory alloy wire can produce plastic deformation at a preset shrinkage rate. The displacement S formula of the memory alloy wire caused by heat shrinkage is:

[0032] S=L*n(Formula 1)

[0033] Wherein, L is the active line length of the memory alloy wire, and n is the shrinkage rate of the memory alloy wire at a preset temperature.

[0034] Specifically, in practical applications, a suitable active line length and a preset temperature may be set according to the size of the electronic device, the magnitude of the magnetic force between the target magnet 112 and the second magnetic member 210 , and the installation position, etc., and the embodiments of the present application may not limit this.

[0035] In some optional embodiments of the present application, such as Figures 3 to 4As shown, the electronic device further includes: a first transmission mechanism, the first transmission mechanism includes a second rotating member 121 and a pushing member 122, one end of the pushing member 122 is connected to the electrodeformable member 130, the other end of the pushing member 122 is connected to the second rotating member 121, and the second rotating member 121 is connected to the first rotating member 120. Wherein, when the electrodeformable member 130 switches between the initial state and the memory state, the electrodeformable member 130 can drive the pushing member 122 to slide, so as to drive the second rotating member 121 to rotate through the sliding of the pushing member 122, and drive the first rotating member 120 to rotate through the rotation of the second rotating member 121. The pushing member 122 can generate movement more smoothly, drive the second rotating member 121 to rotate, and then drive the first rotating member 120 to rotate, and the structure is simple and easy to implement.

[0036] Optionally, in the embodiment of the present application, the second rotating member 121 includes a rotating shaft 140 and a sleeve 124, the rotating shaft 140 is fixedly connected to the first body 100, the sleeve 124 is sleeved on the rotating shaft 140 and can rotate around the rotating shaft 140, and the sleeve 124 is connected to the first rotating member 120. The pushing member 122 is connected to the sleeve 124, and the movement of the pushing member 122 can push the sleeve 124 to rotate around the rotating shaft 140. In this way, under the pushing action of the pushing member 122, the sleeve 124 can rotate, driving at least two magnets 111 on the first rotating member 120 to rotate. The sleeve 124 can be more flexibly rotated through the rotating shaft 140, and the sliding resistance of the pushing member 122 along the axial direction of the rotating shaft 140 can also be reduced.

[0037] In some optional embodiments of the present application, such as Figure 4 As shown, a spiral slideway 125 is provided on the sleeve 124, and a sliding portion 126 is provided on a side of the pusher 122 close to the sleeve 124. The shape of the sliding portion 126 is adapted to the shape of the spiral slideway 125, and the sliding portion 126 is at least partially embedded in the spiral slideway 125 to push the sleeve 124 to rotate around the rotating shaft 140. By embedding at least partially the sliding portion 126 in the spiral slideway 125, the spiral connection between the sleeve 124 and the pusher 122 can be easily achieved.

[0038] In the embodiments of the present application, Figure 4 As shown, the spiral slideway 125 refers to an inclined surface structure formed on the outer wall of the sleeve 124 around the axial direction of the sleeve 124, similar to the thread structure of a screw. The slope of the spiral slideway 125 gradually changes along the axial direction of the sleeve 124. In this way, when the sliding push portion 126 is at least partially embedded in the spiral slideway 125 and pushes the sleeve 124 to move along the axial direction of the rotating shaft 140, the sleeve 124 will be driven to move along the spiral slideway 125, so that the sleeve 124 rotates around the rotating shaft 140.

[0039] Specifically, the shape of the sliding part 126 is adapted to the spiral slide 125, which means that the shape and size of the sliding part 126 are the same as or similar to the shape and size of the spiral slide 125, so that the sliding part 126 can fit into the spiral slide 125, so that the two are tightly connected, thereby improving the stability of the connection between the two.

[0040] Optionally, in the embodiment of the present application, the first rotating member 120 and the second rotating member 121 are an integrally formed structure, which has a simple structure and is easy to produce and process.

[0041] In some optional embodiments of the present application, such as Figure 4 As shown, a plurality of mounting grooves 127 are provided on the circumference of the paddling claw cover 124 , and at least two magnets 111 are embedded in the mounting grooves 127 , so as to enhance the installation stability and reliability of the at least two magnets 111 on the paddling claw cover 124 .

[0042] Optionally, in an embodiment of the present application, the electronic device further includes a second transmission mechanism 150, which is disposed between the electrodeformable member 130 and the pushing member 122, and is used to amplify the deformation of the electrodeformable member 130 and transmit it to the pushing member 122 to drive the pushing member 122 to move.

[0043] In practical applications, due to the limitation of the layout space in the electronic device, the displacement change of the deformation amount generated when the electrodeformable element 130 switches to the memory state may be small, which is not enough to drive the pusher 122 to drive the rotating element 121 to rotate to the target angle, so that the target magnet 112 and the second magnetic element 210 generate magnetic force relative to each other. Therefore, the second transmission mechanism 150 is provided between the electrodeformable element 130 and the pusher 122, which can amplify the deformation amount generated when the electrodeformable element 130 switches to the memory state and transmit it to the pusher 122.

[0044] Specifically, the second transmission mechanism 150 includes a first gear 151 and a second gear 152, the first gear 151 and the second gear 152 are coaxially connected, the first gear 151 is connected to the electrodeformable element 130, and the second gear 152 is connected to the pusher 122. Among them, the diameter of the second gear 152 is greater than the diameter of the first gear 151. In this way, the electrodeformable element 130 is deformed to the memory shape to drive the first gear 151 to rotate. Since the first gear 151 and the second gear 152 are coaxially connected, the angular velocities of the two are the same. At the same time, since the diameter of the second gear 152 is greater than the diameter of the first gear 151, according to the conversion formula of angular velocity and linear velocity:

[0045] v=w*R (Formula 2)

[0046] Among them, v represents the linear velocity, w represents the angular velocity, and R represents the radius of the gear.

[0047] The linear velocity v2 of the second gear 152 is greater than the linear velocity v1 of the first gear 151 , and the second gear 152 transmits the larger linear velocity to the pusher 122 to amplify the deformation amount generated when the electrodeformable element 130 switches to the memory state.

[0048] For example, the radius of the first gear 151 is R1, the radius of the second gear 152 is R2, and according to the above formula 1, the displacement generated by the heat contraction of the memory alloy wire is S. After the displacement amplification effect of the first gear 151 and the second gear 152, the calculation formula of the displacement S3 generated by the pusher 122 is:

[0049] S3=S*(v2 / v1)=S*(R2 / R1)(Formula 3)

[0050] That is, the deformation amount of the electrodeformable element 130 can be amplified by R2 / R1 times through the first gear 151 and the second gear 152.

[0051] Optionally, in the embodiment of the present application, the second transmission mechanism 150 further includes a first rack 154, one end of the first rack 154 is connected to the electrodeformable element 130, and the other end of the first rack 154 is meshed with the first gear 151. By arranging the first rack 154 between the electrodeformable element 130 and the first gear 151, since the first rack 154 is meshed with the first gear 151, the displacement generated by the electrodeformable element 130 can be more accurately transmitted to the first gear 151.

[0052] In some optional embodiments of the present application, the first body 100 further includes a plurality of first sliders 155, and the first rack 154 is slidably connected to the first sliders 155. The first sliders 155 can reduce the resistance encountered in the movement of the first rack 154, and at the same time limit the first rack 154 from sliding along the slideway of the first slider 155 to avoid deviation.

[0053] Optionally, in the embodiment of the present application, the second transmission mechanism 150 also includes a plurality of sequentially meshed third gears 153 , among which the third gear 153 at one end meshes with the second gear 152 , and the third gear 153 at the other end is connected to the pushing member 122 .

[0054] In practical applications, due to the limitation of the layout space in the electronic device, if there is a large distance between the second gear 152 and the pusher 122, the second transmission mechanism 150 may be configured to further include a plurality of third gears 153 that mesh in sequence to transmit the displacement of the second gear 152 to the pusher 122. Since the displacement direction of the pusher 122 needs to be the same as the displacement direction of the electrodeformable element 130, at least two third gears 153 need to be provided, and the number of the third gears 153 is an even number.

[0055] For example, Figures 4 to 5 , a schematic diagram of the structure in which four third gears 153 cooperate with the first gear 151 and the second gear 152 is shown. The third gear 153 meshes with the second gear 152, and two adjacent third gears 153 mesh to transmit the amplified displacement of the second gear 152 to the pusher 122. In practical applications, different radii of multiple third gears 153 can be set according to the layout space in the electronic device, which is conducive to improving the compactness of the structure in the electronic device space.

[0056] It should be noted that, in the embodiment of the present application, the number of the third gears 153 can also be 2, 6, etc., and the embodiment of the present application does not limit the specific number of the third gears 153.

[0057] Optionally, in the embodiment of the present application, the second transmission mechanism 150 further includes a second rack 156, one end of the second rack 156 is connected to the pusher 122, and the other end of the second rack 156 is meshed with the third gear 153. By arranging the second rack 156 between the pusher 122 and the third gear 153, since the second rack 156 is meshed with the third gear 153, the displacement generated by the third gear 153 can be more accurately transmitted to the first gear 151.

[0058] In some optional embodiments of the present application, the first body 100 also includes a plurality of second sliders 157, and the second rack 156 is slidably connected to the second slider 157. In this way, the second rack 156 slides along the second slider 157, which can reduce the resistance encountered by the second rack 156 during movement, and at the same time limit the second rack 156 from sliding along the slide track of the second slider 157 to avoid offset.

[0059] Optionally, the electronic device further comprises a first sensor 300, which is connected to the first body 100 and is used to sense the rotation angle of the rotating member 121, so that the first rotating member 120 rotates to a target angle, so that the target magnet 112 on the first rotating member 120 and the second magnetic member 210 can generate a mutually repelling magnetic force. If the first sensor 300 senses that the rotation angle of the rotating member 121 does not reach the target angle, the electrodeformable member 130 is triggered to be powered on again to shrink due to heat, deform and displace, until the rotation angle of the first rotating member 120 reaches the target angle, thereby improving the relative accuracy of the target magnet 112 and the second magnetic member 210.

[0060] Specifically, the first sensor 300 may include at least one of a Hall sensor and a displacement detector to improve the sensing sensitivity of the first sensor 300 to the rotation angle of the rotating member 121 .

[0061] In some optional embodiments of the present application, the electronic device further includes a second sensor connected to the electrodeformable element 130 to detect the operating temperature of the electrodeformable element 130. When the operating temperature of the electrodeformable element 130 is greater than or equal to a preset temperature, the circuit of the electrodeformable element 130 is disconnected. In this way, the electrodeformable element 130 is prevented from burning out due to excessive temperature, thereby damaging the electronic device.

[0062] Specifically, the second sensor may include at least one of a temperature sensor and a thermistor sensor to improve the sensing sensitivity of the second sensor to the working temperature of the electrodeformable element 130 .

[0063] Optionally, in the embodiment of the present application, the first body 100 further includes a fixing member, which is connected to the electrodeformable member 130 to fix the electrodeformable member 130. Figure 4 As shown, when the electrodeformable element 130 is a memory alloy wire, the fixing element can be configured as a wire clamp to improve the stability of fixing the memory alloy wire.

[0064] In some optional embodiments of the present application, the first body 100 further includes an elastic member 170, which is connected to the pusher 122. When the electrodeformable member 130 is powered off and restored to the initial state, the elastic member 170 drives the pusher 122 to move, so as to drive the second rotating member 121 to rotate, and the target magnet 112 on the first rotating member 120 is driven to leave the position relative to the second magnetic member 210 through the rotation of the second rotating member 121. In this way, at least two magnets 111 on the rotating member 121 are restored to the initial position. When the user needs to switch the electronic device to the folded state, the magnetic pole of the first magnetic member 110 is restored to the opposite magnetic pole of the second magnetic member 210, and the first magnetic member 110 and the second magnetic member 210 attract each other, so that the folded state of the electronic device is achieved.

[0065] Specifically, in the embodiment of the present application, the elastic member 170 may include a spring, which drives the pushing member 122 to move, providing a reliable restoring force for the rotating member 121 to rotate to the initial position, so that the rotating member 121 can be reset more quickly and effectively.

[0066] In the embodiment of the present application, the electronic device further includes a button 500. In the folded state, in response to a pressing operation on the button 500, the electrodeformable element 130 can be energized to deform to the memory shape, thereby realizing automatic unfolding of the electronic device and improving the user experience.

[0067] In summary, the electronic device described in the embodiments of the present application may at least have the following advantages:

[0068] In an embodiment of the present application, the electronic device includes: a first body and a second body, and the first body is rotatably connected to the second body to realize the switching between the folding state and the unfolding state.

The first magnetic member includes at least two magnets, and at least two magnets are sequentially arranged in the circumference of the first rotating member and connected to the first rotating member, and the magnetism of the two adjacent magnets is opposite. The electrodeformable member can switch between the initial shape and the memory shape to drive the first rotating member to rotate. When it is necessary to switch from the folding state to the unfolding state, the electrodeformable member can switch from the initial state to the memory state to drive the first rotating member to rotate until the target magnet in at least two magnets and the second magnetic member repel each other. It avoids the user from frequently opening the folding screen and starting the motor multiple times to consume the power of the electronic device, and increases the battery life of the electronic device. And there is no need to use a large-sized motor to increase the overall thickness of the electronic device, which is conducive to the thinning of the size of the electronic device.
