[0040] like Figure 1 As shown, an embodiment of the present application provides an electronic device, which may include two rotatably connected bodies 1, at least one of the bodies 1 may include a flexible display panel 11 and a state switching component 12, and the state switching component 12 may have a switchable first state and a second state; the state switching component 12 can be used to drive the flexible display panel 11 to bend when switching from the second state to the first state, and can drive the flexible display panel 11 to flatten when switching from the first state to the second state.

[0041] In this embodiment, the two main bodies 1 are rotatably connected, and the rotational connection method can be a hinge connection or a shaft connection, which is not limited to the specific method. The two rotatably connected main bodies 1 enable the electronic device of the present application to have a folding function, and to be in a closed or open state during the process in which the two main bodies 1 rotate relative to each other at the same time and one body 1 is stationary while the other body 1 rotates relative to each other.

[0042] At least one body 1 includes a flexible display panel 11, so that the electronic device of the present application can have only one body 1 to provide a flexible display panel 11 for users to watch, or can be provided with flexible display panels 11 on both sides of the body 1, or multiple flexible display panels 11 can be provided on the body 1 to meet the usage needs of different users. When the two bodies 1 of the electronic device of the present application simultaneously provide the flexible display panel 11 for users to watch, the size and number of the flexible display panels 11 can also be selectively set on the two sides of the two bodies 1.

[0043] At least one body 1 further includes a state switching component 12, the state switching component 12 has a switchable first state and a second state, and the state switching component 12 is used to drive the flexible display panel 11 to bend when switching from the second state to the first state, and to drive the flexible display panel 11 to flatten when switching from the first state to the second state. The present application realizes the switching of the flexible display panel 11 between the flattened state and the bent state through the state component, so that at least one body 1 in the electronic device can be switched between the flattened state and the bent state, thereby enabling the electronic device to have a variety of structural forms. The state switching component 12 can be a plurality of movable plates connected to one side of the flexible display panel 11, and the flexible display panel 11 can be switched between the bent and flattened states through the movement of the movable plates. It can also be a memory alloy connected to the flexible display panel 11, and the strain force stored in the memory alloy can be used to drive the flexible display panel 11 to deform during the rotation of the main body 1. The flexible display panel 11 can also be driven to bend and flatten by the linear driving force provided by a linear motor, or the main body 1 can be driven to bend by a gear transmission component to drive the flexible display panel 11 to bend and flatten. The specific details are not limited, and the state switching component 12 can be used to drive the flexible display panel 11 to bend when switching from the second state to the first state, and drive the flexible display panel 11 to flatten when switching from the first state to the second state.

[0044] When the state switching component 12 is used to switch from the second state to the first state, the bending direction of the flexible display panel 11 can be set to be concave toward the user, so that the flexible display panel 11 conforms to the physiological structure of the human eye and reduces the visual fatigue of the user caused by the use of the electronic device. At the same time, the flexible display panel 11 concave toward the user can provide the user with a wider viewing angle, enhance the visual immersion of the edge of the screen, and thus improve the user's experience. The bending direction of the flexible display panel 11 can also be set to convex toward the user, so that the flexible display panel 11 in the bent state can provide directional light concentration and a specific viewing angle to form a specific visual effect of the flexible display panel 11 to meet the use needs of specific users. In the electronic device of the present application, when the state switching component 12 is used to switch from the second state to the first state, the bending direction of the flexible display panel 11 is not limited and can be adjusted according to the different use needs of different users.

[0045] The present application provides an electronic device, comprising two bodies 1 connected in rotation, at least one of the bodies 1 comprising a flexible display panel 11 and a state switching component 12, the state switching component 12 having a switchable first state and a second state; the state switching component 12 is used to drive the flexible display panel 11 to bend when switching from the second state to the first state, and to drive the flexible display panel 11 to flatten when switching from the first state to the second state. The present application enables the flexible display panel 11 of the body 1 to switch between the flattened state and the bent state by using the state switching component 12 having two switchable states, so that the electronic device has a diversified structural form to meet the usage requirements of different users.

[0046] Further, such as Figures 1 to 4 As shown, in some embodiments, it may also include: a first rotating shaft 2; the two bodies 1 can be rotationally connected through the first rotating shaft 2, and the state switching component 12 can be connected to the first rotating shaft 2; when the first rotating shaft 2 is rotated to a first angle, the state switching component 12 can be switched from the second state to the first state; when the first rotating shaft 2 is rotated to a second angle, the state switching component 12 can be switched from the first state to the second state.

[0047] In this embodiment, in order to realize the rotational connection between the two bodies 1, the present application is provided with a first rotating shaft 2, which is arranged between the two bodies 1. In terms of quantity, it can be a single-axis structure, a double-axis structure or a multi-axis structure; in terms of the relative position relationship between the two bodies 1, it can be a raised rotating shaft or a sunken rotating shaft, wherein the sunken rotating shaft can reduce the volume of the two bodies 1 when closed and reduce the thickness of the electronic device, and the raised rotating shaft can provide a larger opening and closing angle; on the basis of the above, the first rotating shaft 2 can adopt a torque rotating shaft, a gasket rotating shaft, a flip rotating shaft, etc., without limitation, as long as the rotational connection between the two bodies 1 can be realized.

[0048] The state switching component 12 is used to drive the flexible display panel 11 to bend when switching from the second state to the first state, and to drive the flexible display panel 11 to flatten when switching from the first state to the second state. In the present application, the first rotating shaft 2 is set so that during the relative rotation of the two bodies 1, the first rotating shaft 2 is rotated to different angles to realize the state switching of the state switching component 12. In this application, it is set that when the first rotating shaft 2 is rotated to the first angle, the state switching component 12 is switched from the second state to the first state; when the first rotating shaft 2 is rotated to the second angle, the state switching component 12 is switched from the first state to the second state. The first angle can be the maximum opening angle when the electronic device is turned on, or it can be any preset angle less than the maximum opening angle. In this case, after the state switching component 12 is switched to the first state, the bent flexible display panel 11 can continue to adjust the angle until the first rotating shaft 2 is rotated to the maximum opening angle. At the second angle, the state switching component 12 switches the state in the opposite direction, and the first rotating shaft 2 moves in the opposite direction, that is, the second angle is the opposite first angle to realize that the bent flexible display panel 11 is restored to the flattened state.

[0049] like Figure 1 As shown, in some embodiments, the angle at which the electronic device is suitable for the user can be the case where the relative angle between the two bodies 1 is greater than 40°. In this case, the first angle can be any angle at which the relative angle between the two bodies 1 is greater than 40°. At this angle, the state switching component 12 can drive the flexible display panel 11 to switch from flattening to bending, so that when the electronic device is switched to an angle suitable for the user, the state switching component 12 can be linked with the first rotating shaft 2 to achieve state switching, so that when the user turns on the electronic device for use, the flexible display panel 11 that needs to be displayed to the user can be switched to a bent state under the action of the state switching component 12, thereby improving the user experience.

[0050] In other embodiments, when the electronic device does not need to be used by the user, that is, when it has finished using or is idle, the relative angle between the two bodies 1 may be less than 20°. In this case, the second angle may be any angle at which the relative angle between the two bodies is less than 20°. At this angle, the state switching component 12 may drive the flexible display panel 11 to switch from bending to flattening, so that when the user finishes using the electronic device and turns off the electronic device, the flexible display panel 11 may switch from bending back to a flattened state under the action of the state switching component 12. At this time, the flexible display panel 11 in the flattened state is convenient for the storage of the electronic device, and can also save the space required for the entire electronic device. At the same time, it can protect the flexible display panel 11 and prevent it from bending for a long time and affecting its service life. Figure 2As shown, in some embodiments, the second angle may be 0°, at which time the two bodies 1 are buckled in parallel, and the flexible display panel 11 is in a flattened state and is located between the two bodies 1 .

[0051] Further, such as Figure 4 As shown, in some embodiments, the state switching component 12 may include a plurality of movable plate bodies 121 and a rotating shaft transmission member 122. In the second state, the plurality of movable plate bodies 121 may be arranged along a first direction A parallel to the rotation axis of the first rotating shaft 2, and two adjacent movable plate bodies 121 may be rotatably connected; the rotating shaft transmission member 122 may be connected to the first rotating shaft 2, and the rotation of the first rotating shaft 2 may drive the rotating shaft transmission member 122 to move. The plurality of movable plate bodies 121 may be respectively connected to the rotating shaft transmission member 122 through a connecting member 123; wherein the rotating shaft transmission member 122 may be used to drive the connecting member 123 to move when the first rotating shaft 2 rotates, so as to rotate at least one movable plate body 121 among the plurality of movable plate bodies 121, thereby realizing switching from the second state to the first state.

[0052] In this embodiment, in order to realize that the state switching component 12 can drive the flexible panel to bend and flatten during the switching process between the first state and the second state, the state component of the present application may include a plurality of movable plate bodies 121 and a rotating shaft transmission member 122. In the second state, that is, when the flexible display panel 11 is flattened, the plurality of movable plate bodies 121 can be arranged along a first direction A parallel to the rotation axis of the first rotating shaft 2, that is, a plurality of movable plate bodies 121 arranged in parallel can form a main body 1 including a flexible display panel 11, and adjacent two movable plate bodies 121 can be rotatably connected, and the rotational connection can be achieved by setting a rotating shaft, a hinge, etc. It can be understood that the plurality of movable plate bodies 121 serve as carriers of the flexible display panel 11, and the flexible display panel 11 can be presented in different states through the movement of the plurality of movable plate bodies 121.

[0053] The shaft transmission member 122 and the movable plate body 121 are connected by a connecting member 123, so that when the shaft transmission member 122 is driven to move during the rotation of the first shaft 2, the shaft transmission member 122 can drive at least one of the multiple movable plate bodies 121 to rotate through the connecting member 123, so that the at least one rotating movable plate body 121 can drive the flexible display panel 11 to bend or flatten, and the bending or flattening is determined by the rotation direction of the first shaft 2. The shaft transmission member 122 can be a mechanical structure such as a lead screw, a linear motor, a gear assembly, etc., and the connecting member 123 can be a pull rod, a pull rope, a cable, etc., and both ends are connected between the movable plate body 121 and the shaft transmission member 122.

[0054] In some embodiments, the shaft transmission member 122 can be a gear assembly, and the connecting member 123 can be a cable. The gear assembly can include a worm wheel and a worm, wherein the worm is coaxially arranged with the first shaft 2, and the two ends of the cable are respectively connected to the worm wheel and at least one movable plate body 121. When the first shaft 2 rotates, the worm rotates at the same time, and the worm meshing drives the worm wheel to rotate, pulling the cable and then pulling the movable plate body 121 connected to the corresponding cable to rotate relative to other movable plate bodies 121, thereby realizing the state switching component 12 switching from the second state to the first state, and the flexible display panel 11 bends under the action of at least one rotating movable plate body 121.

[0055] In other embodiments, the shaft transmission member 122 may be a linear motor, and the connecting member 123 may be a pull rod. The linear motor is connected to the first shaft 2, and the two ends of the pull rod are respectively connected to the linear motor and at least the movable plate body 121. When the first shaft 2 rotates, the linear motor rotates at the same time, driving the pull rod to perform linear motion in a preset direction. The movable plate body 121 corresponding to the pull rod is pulled by the pull rod and rotates relative to other movable plate bodies 121, thereby realizing the state switching component 12 switching from the second state to the first state, and the flexible display panel 11 bends under the action of at least one rotating movable plate body 121.

[0056] Further, such as Figure 4 As shown, in some embodiments, the plurality of movable plate bodies 121 may be an odd number, the target plate body 124 is centered among the plurality of movable plate bodies 121, the movable plate bodies 121 on both sides of the target plate body 124 may be symmetrically arranged relative to the target plate body 124, the first rotating shaft 2 and the rotating shaft transmission member 122 may be arranged corresponding to the target plate body 124, the movable plate bodies 121 on both sides of the target plate body 124 may be respectively connected to the rotating shaft transmission member 122 through the connecting member 123; wherein the rotating shaft transmission member 122 may be used to drive the connecting member 123 to move when the first rotating shaft 2 rotates, so that the movable plate bodies 121 on both sides of the target plate body 124 rotate toward the target plate body 124, thereby realizing switching from the second state to the first state.

[0057] In this embodiment, the plurality of movable plates 121 may be an odd number, and the target plate 124 is the central one among the plurality of movable plates 121, and the movable plates 121 on both sides of the target plate 124 may be symmetrically arranged relative to the target plate 124. The target plate 124, as the central plate among the plurality of movable plates 121, serves as a force point to drive the rotation of the main body 1 relative to another main body 1, and is helpful for calibration of the flexible display panel 11 when it is bent, and ensures the display quality after bending. When driving the target plate 124, the rotation of the first rotating shaft 2 may cause the rotating shaft transmission member 122 to drive the connecting member 123 to pull the movable plates 121 on both sides of the target plate 124, and since the movable plates 121 are all rotationally connected, the movable plates 121 on both sides of the target plate 124 will rotate toward the target plate 124, thereby realizing that the flexible display panel 11 is driven to bend when the state switching component 12 switches from the second state to the first state. When the target plate 124 is driven in the reverse direction, the movable plates 121 on both sides of the target plate 124 will rotate away from the target plate 124 , thereby driving the flexible display panel 11 to flatten when the state switching component 12 switches from the first state to the second state.

[0058] In one embodiment of the present application, there may be five movable plate bodies 121, and two movable plate bodies 121 may be symmetrically arranged on both sides of the target plate body 124 in the center of the five movable plate bodies 121, to drive the target plate body 124, and the first rotating shaft 2 rotates to make the rotating shaft transmission member 122 drive the four movable plate bodies 121 on both sides of the target body 1, so that the two movable plate bodies 121 on one side of the target plate body 124 and the two plate bodies on the other side all rotate toward the target plate body 124, and the five movable plate bodies 121 form a curved surface with a certain curvature, thereby driving the flexible display panel 11 to bend under the action of the curved surface.

[0059] In another embodiment of the present application, there may be three movable plate bodies 121, and among the three movable plate bodies 121, there may be one movable plate body 121 on each side of the target plate body 124. The rotation of the first rotating shaft 2 enables the three movable plate bodies 121 to form a curved surface that drives the flexible display panel 11 to bend. In this embodiment, the arrangement cost of the movable plate bodies 121 is relatively low. At the same time, in order to realize the bending of the flexible display panel 11, only two connecting members 123 need to be set to realize that the movable plate bodies 121 on both sides of the target plate body 124 can be driven to rotate, thereby saving costs.

[0060] In another embodiment of the present application, there can be 7 movable plate bodies 121, and there are 3 movable plate bodies 121 on each side of the target plate body 124 among the 7 movable plate bodies 121, and they are all symmetrically arranged relative to the target plate body 124. The rotation of the first rotating shaft 2 can also make the 7 movable plate bodies 121 form a curved surface that drives the flexible display panel 11 to bend. In this embodiment, the 7 movable plate bodies can make the bending of the flexible display panel 11 have a more precise bending amplitude, so that the flexible display panel 11 can present a better display effect.

[0061] Further, such as Figures 4 to 6 As shown, in some embodiments, the connecting member 123 can be a pull rope; the rotating shaft transmission member 122 can be two screws, which are respectively connected to the two ends of the first rotating shaft 2, the first end of the pull rope is connected to the screw, and the second end of the pull rope is connected to the movable plate body 121 on both sides of the target plate body 124.

[0062] In this embodiment, the connecting member 123 can be a pull rope, which is small in size, light in weight, occupies a small volume, and has good environmental adaptability, which is conducive to its wiring in the narrow space between the two main bodies 1 to achieve the connection between the rotating shaft transmission member 122 and the movable plate body 121.

[0063] In the present application, the shaft transmission member 122 may be two lead screws, which have high stability, transmission accuracy and transmission efficiency, and can provide a linear stroke during the rotation of the first shaft 2, and can then pull the pull rope to pull the corresponding movable plate 121 connected to the other end of the pull rope to rotate relative to the other movable plate 121. In order to make the flexible display panel 11 present a symmetrical bending trend, two lead screws are required to be arranged at both ends of the first shaft 2, and at the same time, each lead screw is connected to the movable plate 121 on one side of the target plate 124 through a pull rope, so that the movable plates on both sides of the target plate 124 can be pulled at the same time, and finally a curved surface symmetrical to the target plate 124 is formed to support the bending of the flexible display panel 11.

[0064] In some embodiments, two lead screws are respectively connected to the two ends of the first rotating shaft 2, and the two lead screws are connected to the two ends of the first rotating shaft 2 with reverse threads. When the user turns on the electronic device for use, the first rotating shaft 2 rotates, driving the lead screws on both sides to rotate simultaneously and simultaneously providing a first linear driving force toward the first rotating shaft 2. Under the action of the first linear driving force, the pull rope pulls the movable plate bodies 121 on both sides of the target plate body 124 to rotate toward the target plate body 124. When the movable plate bodies 121 on both sides of the target plate body 124 rotate to a certain angle to form a curved surface with a certain curvature, the state switching component 12 completes the process of switching from the second state to the first state, and the flexible display panel 11 bends under the support of the curved surface.

[0065] In other embodiments, when the user finishes using the electronic device, the first rotating shaft 2 is rotated in the opposite direction, driving the lead screws on both sides of the first rotating shaft 2 to rotate simultaneously and simultaneously having a second linear driving force away from the direction of the first rotating shaft 2. Under the action of the second linear driving force, the pull rope pulls the movable plate bodies 121 on both sides of the target plate body 124 away from the target plate body 124 to rotate. When the movable plate bodies 121 on both sides of the target plate body 124 are completely restored to the initial state of being arranged along the first direction A, the state switching component 12 completes the process of switching from the first state to the second state, and the flexible display panel 11 is flattened under the support of all the movable plate bodies 121 arranged flat.

[0066] Further, such as Figure 5 and Figure 6 As shown, in some embodiments, a first through hole 1241 extending along the first direction A may be provided at one end of the target plate body 124 facing the first rotating shaft 2, and the first through hole 1241 may be at least partially sleeved on the lead screw and the first rotating shaft 2; a second through hole 1211 extending along the first direction A may be provided at one end of the movable plate body 121 on both sides of the target plate body 124 facing the first rotating shaft 2, and the pull rope may be at least partially passed through the second through hole 1211 and connected to the corresponding movable plate body 121.

[0067] In this embodiment, the first through hole 1241 and the second through hole 1211 extending along the first direction A are opened at one end of all the movable plate bodies 121 including the target plate body 124 facing the first rotating shaft 2. Since the two lead screws serving as the rotating shaft transmission parts 122 in the state switching component 12 are respectively connected to the first rotating shaft 2, and the multiple movable plate bodies 121 including the target plate body 124 are respectively connected to the lead screws through pull ropes, the present application uses the first through hole 1241 to be sleeved on the lead screw and the first rotating shaft 2, and the second through hole 1211 to form a channel for passing the pull rope, which can ensure the concealment of the switching process of the state switching component 12 between the first state and the second state, and improve the aesthetics of the electronic device during use. At the same time, the first through hole 1241 and the second through hole 1211 provide the space required for the connection between the lead screw and the movable plate bodies 121 on both sides of the target plate body 124, avoiding structural collision and ensuring smooth and safe switching of the state switching component 12 between the first state and the second state. In addition, the setting of the first through hole 1241 and the second through hole 1211 can also protect the first rotating shaft 2, the lead screw, and the pull rope to avoid wear between them and external components and affect their service life.

[0068] Further, such as Figure 5 As shown, in some embodiments, a second rotating shaft 3 extending along a second direction B perpendicular to the first direction A may be provided between two adjacent movable plates 121 , and a limiting member may be provided on the second rotating shaft 3 , which may be used to limit the maximum rotation angle of the second rotating shaft 3 .

[0069] In this embodiment, in order to achieve a rotational connection between two adjacent movable plate bodies 121, the movable plate bodies 121 on both sides of the target plate body 124 are rotated toward the target plate body 124 to achieve switching from the second state to the first state. The present application provides a second rotating shaft 3 extending along a second direction B perpendicular to the first direction A between the two adjacent movable plate bodies 121, and in order to limit the bending amplitude of the flexible display panel 11 in the first state, the present application provides a limiting member on the second rotating shaft 3, and the limiting member is used to limit the maximum rotation angle of the second rotating shaft 3. The limiting member can be a limiting spring built into the second rotating shaft 3, or it can be a limiting block or limiting pin set on the rotation path of the second rotating shaft 3, or a limit switch can be used to limit the maximum rotation angle. It should be noted that the maximum rotation angle also includes the rotation angle of the second rotating shaft 3 in both clockwise and counterclockwise directions.

[0070] The present application limits the maximum rotation angle of the second rotating shaft 3, so that the flexible display panel 11 of the electronic device can present a good visual effect after being bent, thereby improving the user experience. In one embodiment of the present application, the maximum rotation angle of the second rotating shaft 3 can be limited to 2°~6° by a limiter. In one embodiment of the present application, the limiter can limit the maximum rotation angle of the second rotating shaft 3 to 3°. When the maximum rotation angle of the second rotating shaft 3 is limited to 3°, after the movable plates 121 on both sides of the target plate 124 rotate toward the target plate 124, the state switching component 12 switches from the second state to the first state, and the flexible display panel 11 bends. Compared with when the maximum rotation angle of the second rotating shaft 3 is limited to 2°, the bending amplitude of the flexible display panel 11 is larger, which can provide the user with a wider viewing angle and better visual immersion. Compared with when the maximum rotation angle of the second rotating shaft 3 is limited to 6°, the curvature transition of the flexible display panel 11 is smoother, and the surface of the flexible display panel 11 is also smoother.

[0071] Further, such as Figure 6 As shown, in some embodiments, an energy storage member 4 may be further provided between two adjacent movable plate bodies 121, and the energy storage member 4 is sleeved on the second rotating shaft 3 and has two ends respectively connected to the two adjacent movable plate bodies 121; wherein the energy storage member 4 may be used to store energy force during the process of the state switching component 12 switching from the second state to the first state, and the state switching component 12 switches from the first state to the second state during the process of the energy storage member 4 releasing the force.

[0072] In this embodiment, in order to increase a certain elastic buffer during the rotational connection between the two movable plates 121, and at the same time provide elastic support for the switching of the flexible display panel 11 from bending to flattening, the present application further provides an energy storage member 4 between the two adjacent movable plates 121. The energy storage member 4 can be a torsion spring, which is sleeved on the second rotating shaft 3 and connected to the movable plates 121 on both sides thereof through both ends. During the relative rotation of the two movable plates 121, an elastic force is generated, so that the first state can be switched to the second state under the action of the elastic force. The energy storage member 4 can also be an elastic element such as rubber or silicone, or a memory alloy element with high elasticity and shape memory effect, which can generate an elastic force during the switching from the second state to the first state, so that the first state can be switched to the second state under the action of the elastic force.

[0073] Furthermore, in some embodiments, it may also include: a driving member, which can be used to drive the state switching component 12 to switch from the first state to the second state; and / or, can be used to drive the state switching component 12 to switch from the second state to the first state.

[0074] In this embodiment, in order to drive the state switching component 12 to switch between the first state and the second state, the electronic device of the present application further includes a driving member, which can be connected to the state switching component 12 so that it can deform and store strain during the process of switching the electronic device between the open and closed states, and can release stress to provide driving force during the process of deformation recovery to a preset or memorized shape, so as to realize the state switching component 12 switching between the first state and the second state, so that the flexible display panel 11 switches between the bent and flattened states. The driving member can be a shape memory polymer such as polyurethane, polyester, epoxy resin, or a memory alloy such as nickel-titanium-based, copper-based, and iron-based, all of which can realize the above-mentioned storage of strain and release stress to provide driving force during the deformation recovery process. In a usage scenario, the state switching component 12 is in the first state, at which time the flexible display panel 11 is bent, and the driving member is set to provide a driving force to drive the state switching component 12 to switch from the first state to the second state. When switching to the second state, the flexible display panel 11 is flattened. In another usage scenario, the state switching component 12 is in the second state, at which time the flexible display panel 11 is flattened, and the driving member is set to provide a driving force to drive the state switching component 12 to switch from the second state to the first state. When switching to the first state, the flexible display panel 11 bends.

[0075] Furthermore, in some embodiments, the driving member may be a memory alloy.

[0076] In this embodiment, the driving member can be a memory alloy such as nickel-titanium-based, copper-based, iron-based, etc. The memory alloy has high elasticity and shape memory effect. The high elasticity enables the memory alloy to withstand elastic limits far exceeding those of ordinary metals, and enables it to deform and store strain during the process of switching the electronic device between the open and closed states. The shape memory effect allows it to release stress to provide driving force during the recovery process of the deformation to a preset or memorized shape, so as to realize the state switching component 12 switching between the first state and the second state, so that the flexible display panel 11 switches between the bent and flattened states. In addition, the memory alloy can realize precise size control and driving, ensuring that a stable driving force is provided for the state switching component 12 to switch between the first state and the second state. At the same time, the memory alloy also provides good wear resistance, fatigue resistance and corrosion resistance, increasing the service life of the electronic device and ensuring long-term stable working performance.
