In this embodiment, as shown in fig. 4, the flipping mechanism 200 further includes a first rotating bracket 2401 and a second rotating bracket 2402 which are oppositely arranged, the first end 213 is connected to the first rotating bracket 2401, and the second end 214 is connected to the second rotating bracket 2402. The first rotating bracket 2401 is sleeved and fixed at the first ends 213 of the first linkage rod 211 and the second linkage rod 212, and the first telescopic element 310 is fixedly connected to the first rotating bracket 2401 to realize the fixed connection with the first end 213. The second rotating bracket 2402 is sleeved and fixed at the second ends 214 of the first linkage rod 211 and the second linkage rod 212, and the second telescopic element 320 is fixedly connected to the second rotating bracket 2402 to realize the fixed connection with the second end 214. The telescoping member 300 includes a first telescoping member 310 and a second telescoping member 320. One end of the first expansion piece 310 is connected to one end of the linkage block 230 to realize the fixed connection of the first expansion piece 310 with the first toggle wing 221 and the second toggle wing 222. The other end of the first telescopic member 310 is fixedly connected to the first rotating bracket 2401 to change the distance between the first toggle wing 221 and the second toggle wing 222 and the first end 213 of the linkage rod 210. One end of the second expansion piece 320 is connected to the other end of the linkage block 230 to realize the fixed connection of the second expansion piece 320 with the first toggle wing 221 and the second toggle wing 222.

Preferably, first and

second telescoping members

310 and 320 are positioned intermediate the gap between first and

second linkage rods

211 and 212. With the above arrangement, the first telescopic member 310 and the second telescopic member 320 can apply a force parallel to the axial direction to the linkage block 230, and at the same time, the installation of the first telescopic member 310 and the second telescopic member 320 is facilitated.

Through the above arrangement, the first extensible member 310 and the second extensible member 320 drive the linkage block 230 to move towards the direction close to the first end 213 or the direction close to the second end 214, so as to drive the first toggle wing 221 and the second toggle wing 222 to move along the axial direction of the linkage rod 210, thereby realizing the radial rotation of the first toggle wing 221 and the second toggle wing 222 along the linkage rod 210. Of course, in other embodiments, the first extensible member 310 and the second extensible member 320 may also be directly and fixedly connected to the first toggle wing 221 and the second toggle wing 222 without the linkage block 230, so as to drive the first toggle wing 221 and the second toggle wing 222 to move. For example: one end of the first extensible member 310 is connected to the first toggle wing 221 and the second toggle wing 222, and the other end of the first extensible member 310 is connected to the first rotating bracket 2401, so as to control the first toggle wing 221 and the second toggle wing 222 to move along the axial direction of the linkage rod 210; one end of the second expansion piece 320 is connected to the first toggle wing 221 and the second toggle wing 222, and the other end of the second expansion piece 320 is connected to the second rotating bracket 2402, so as to control the axial movement of the first toggle wing 221 and the second toggle wing 222 along the linkage rod 210. Further alternatively, when the first extensible member 310 and the second extensible member 320 can apply a pulling force or a pushing force to the first toggle wing 221 and the second toggle wing 222, respectively, the connection relationship between the first extensible member 310 and the second extensible member 320 and the first toggle wing 221 and the second toggle wing 222 may be: two ends of the first telescopic member 310 are respectively fitted to the first dial wing 221 and the first rotating bracket 2401 to control the axial movement of the first dial wing 221 along the linkage rod 210. Two ends of the second telescopic member 320 are respectively matched with the second dial wing 222 and the second rotating bracket 2402 to control the axial movement of the second dial wing 222 along the linkage rod 210.

In this embodiment, first telescoping member 310 and second telescoping member 320 are both memory alloy wires. When the memory alloy wire is electrified, the temperature of the memory alloy wire can be rapidly increased, and once the temperature reaches a threshold value, the memory alloy wire can be restored to the original length. The length of the first telescopic member 310 and the second telescopic member 320 can be changed by changing the temperature thereof, so as to drive the first toggle wing 221 and the second toggle wing 222 to move along the axial direction of the linkage rod 220.

In the above structure, the first telescopic member 310 and the second telescopic member 320 are made of memory alloy wires, so the force application directions of the first telescopic member 310 and the second telescopic member 320 to the toggle wing 220 are unidirectional. The first telescoping member 310 and the second telescoping member 320 exert opposing forces on the flipping mechanism 200, and the first telescoping member 310 and the second telescoping member 320 exert forces on the flipping mechanism 200, respectively. Of course, the first telescopic element 310 and the second telescopic element 320 may also be other elements which exert a unidirectional force on the toggle wing 220.

Alternatively, in other embodiments, the direction of the force applied to the toggle wing 220 by the first telescopic member 310 and the second telescopic member 320 can be bidirectional. The first telescoping member 310 and the second telescoping member 320 may apply force to the flipping mechanism 200 independently, or the first telescoping member 310 and the second telescoping member 320 may simultaneously apply force to the flipping mechanism 200. For example, the first and

second telescoping members

310 and 320 may be extendable or retractable push rods.

As shown in fig. 4, the linkage rod 210 includes a first linkage rod 211 and a second linkage rod 212, each of the first linkage rod 211 and the second linkage rod 212 includes a first end 213 and a second end 214, the first linkage rod 211 is in threaded connection with the first toggle wing 221, and the second linkage rod 212 is in threaded connection with the second toggle wing 222. The two ends of the linkage block 230 are respectively sleeved on the first linkage rod 211 and the second linkage rod 212, and the two ends are respectively clamped on the first toggle wing 221 and the second toggle wing 222. Through setting up first gangbar 211 and second gangbar 212, be convenient for realize the assembly of first stirring wing 221 and second stirring wing 222, simultaneously, when not setting up the linkage piece, be convenient for realize the asynchronous motion of first stirring wing and second stirring wing.

Further, the flipping mechanism 200 further comprises a sliding wing 250, and the sliding wing 250 is fixedly connected with the display mechanism 100. The sliding wing 250 is provided with a guide groove 253, the toggle wing 220 is provided with a guide post 223, and the guide post 223 can be slidably arranged in the guide groove 253. The guide groove 253 forms an angle different from zero with the axial direction of the linkage rod 210 so that the sliding wing 250 can move toward or away from the linkage rod 210. During the process that the toggle wing 220 moves along the axial direction of the linkage rod 210 and rotates along the radial direction, the guide column 223 can drive the sliding wing 250 to move in the direction close to or far away from the linkage rod 210. By controlling the movement of the sliding wings 250, at least part of the display mechanism 100 can move towards the direction close to or away from the linkage rod 210, so that when the display mechanism 100 bends along with the dial wing 220, the part far away from the linkage rod 210 in the display mechanism 100 cannot extrude the part close to the linkage rod 210, the phenomenon that the display mechanism 100 is wrinkled or stressed unevenly is avoided, and the display mechanism 100 is protected.

The sliding wings 250 include a first sliding wing 251 and a second sliding wing 252, the first sliding wing 251 is connected to the first dial wing 221 and connected to the first display portion 110, the second sliding wing 252 is connected to the second dial wing 222 and connected to the second display portion 120, the first sliding wing 251 and the second sliding wing 252 can rotate and can move towards the direction close to or away from the linkage rod 210, so as to drive the first display portion 110 and the second display portion 120 to rotate and drive at least a part of the first display portion 110 and the second display portion to move towards the direction close to or away from the linkage rod 210.

As shown in fig. 1 and 2, each of the first display part 110 and the second display part 120 includes an active area 130 and a connection area 140. The connection region 140 of the first display part 110 is connected with the connection region 140 of the second display part 120, and the connection region 140 faces the first and second linkage bars 211 and 212 and is stationary with respect to the linkage bar 210. The active area 130 is remote from the first linkage bar 211 and the second linkage bar 212, and the active area 130 of the first display 110 is rotatable relative to the first linkage bar 211 and the active area 130 of the second display 120 is rotatable relative to the second linkage bar 212. The first sliding wing 251 is fixed to the movable region 130 of the first display part 110, and the second sliding wing 252 is fixed to the movable region 130 of the second display part 120. When the movable region 130 rotates relative to the linkage rod 210, the movable region 130 can move towards or away from the linkage rod 210 under the driving of the sliding wing 250, so as to ensure that the connecting region 140 is not extruded or pulled by the movable region 130 to deform.

As shown in fig. 1-3, the display mechanism 100 further includes a first bracket 150 and a second bracket 160. In the present embodiment, the first bracket 150 and the second bracket 160 are used to support the first display part 110 and the second display part 120 to protect the first display part 110 and the second display part 120. The first bracket 150 is fixed to the movable region 130 of the first display portion 110 and is fixedly connected to the second sliding wing 251 to drive the movable region 130 of the first display portion 110 to rotate along the axial direction of the first linkage rod 211 and move in a direction close to or away from the first linkage rod 211. The second bracket 160 is fixed to the movable region 130 of the second display part 120 to drive the movable region 130 of the second display part 120 to rotate along the axial direction of the second linkage rod 212 and move towards or away from the second linkage rod 212.

As shown in fig. 5 and 6, the flipping mechanism 200 is switchable between the folded state 20 and the unfolded state 30.

First telescoping member 310 and second telescoping member 320 are used to provide the motive force for switching canting mechanism 200 between the two states. When the turnover mechanism 200 is switched from the folded state 20 to the unfolded state 30, or from the unfolded state 30 to the folded state 20, the temperatures of the first extensible member 310 and the second extensible member 320 are changed (heated), and in other states, the first extensible member 310 and the second extensible member 320 are at normal temperature. In the use process, when two ends of the memory alloy wire are electrified, the memory alloy wire can rapidly generate heat, and when the temperature reaches a set value, the memory alloy wire can be restored to a default state which is designed in advance.

Generally, when the memory alloy wire is in the default design state, the telescopic dimension is shorter. When the flipping mechanism 200 can be switched between the folded state 20 and the unfolded state 30, the memory alloy wire is stretched, and the length of the stretching dimension is long, so that the memory alloy wire is deformed to a certain extent and is separated from the original default state. After the stretched alloy wire is heated (electrified), the alloy wire retracts to the length of the original design default state to offset deformation, and therefore a large pulling force and a large displacement are provided.

As shown in fig. 5, when the flipping mechanism 200 is in the folded state 20, the active region 130 of the first display portion 110 and the active region 130 of the second display portion 120 are disposed opposite to each other, and the plane of the active region 130 of the first display portion 110 is parallel to the plane of the active region 130 of the second display portion 120, and the plane of the active region 130 is perpendicular to the plane of the connecting region 140. The first toggle wing 221 and the second toggle wing 222 are close to the second end 214, the first extensible member 310 is in a stretched state, the second extensible member 320 is in an original state, and the temperatures of the first extensible member 310 and the second extensible member 320 are normal temperature. Due to the material properties, the tension of the first telescopic member 310 is not enough to push the linkage block 230 to move. The first sliding wing 251 and the second sliding wing 252 are close to the linkage rod 210, so that the first display part 110 and the second display part 120 are connected to form a smooth 'U-shaped' structure. In this case, the electronic device 10 may display the screen only on one of the first display unit 110 and the second display unit 120, and of course, the first display unit 110 and the second display unit 120 may display the screens simultaneously.

As shown in fig. 6, when the flipping mechanism 200 is in the unfolded state 30, the plane of the first display part 110 and the plane of the second display part 120 are overlapped, and the upper surfaces of the first display part 110 and the second display part 120 are connected to form a flat surface. At this time, the first display unit 110 and the second display unit 120 can simultaneously display screens. The first toggle wing 221 and the second toggle wing 222 are close to the first end 213, the first extensible member 310 is in an original state, and the second extensible member 320 is in a stretched state. The first sliding wing 251 and the second sliding wing 252 are far away from the linkage rod 210. At this time, the first display unit 110 and the second display unit 120 of the electronic device 10 can simultaneously display screens.

When the flipping mechanism 200 is switched from the folded state 20 to the unfolded state 30, the first telescopic part 310 is powered on to heat up, the first telescopic part 310 contracts rapidly, and applies an acting force towards the first end 213 to the toggle wing 220, so that the first toggle wing 221 and the second toggle wing 222 move towards the direction close to the first end 213, the first toggle wing 221 and the second toggle wing 222 move along the axial direction of the first linkage rod 211 and the second linkage rod 212, and the second telescopic part 320 is driven by the first toggle wing 221 and the second toggle wing 222 to elongate. Meanwhile, the first toggle wing 221 rotates in a clockwise direction, and the second toggle wing 222 rotates in a counterclockwise direction. In this embodiment, in order to match the movement of the first toggle wing 221 and the second toggle wing 222, the guide groove 253 on the sliding wing 250 extends away from the linkage bar 210 in the direction from the first end 213 to the second end 214. Therefore, when the first toggle wing 221 and the second toggle wing 222 move towards the second end 214, the first sliding wing 251 and the second sliding wing 252 move away from the linkage rod 210 under the driving of the guiding column 223 of the toggle wing 220, and rotate along with the rotation of the first toggle wing 221 and the second toggle wing 222 until the first expansion piece 310 returns to the original state, at this time, the flipping mechanism 200 moves to the unfolding state 30, and the first expansion piece 310 is powered off. Through the above arrangement, the first sliding wing 251 and the second sliding wing 252 can drive the movable region 130 of the first display part 110 and the movable region 130 of the second display part 120 to move in the direction away from the connection region 140, so that the distance between the two movable regions 130 is matched with the width of the two connection regions 140, the wrinkles of the first display part 110 and the second display part 120 can be effectively reduced, and the first display part 110 and the second display part 120 are prevented from being damaged due to extrusion deformation and uneven stress caused by switching of the states of the flipping mechanism 200.

When the flipping mechanism 200 is switched from the unfolding state 30 to the folding state 20, the second telescopic member 320 is powered to heat up, the second telescopic member 320 contracts rapidly, and applies an acting force to the toggle wing 220 toward the second end 214, so that the first toggle wing 221 and the second toggle wing 222 move in a direction close to the second end 214, the first toggle wing 221 and the second toggle wing 222 move in the axial direction of the first linkage rod 211 and the second linkage rod 212, and the first telescopic member 310 is driven by the first toggle wing 221 and the second toggle wing 222 to be elongated. Meanwhile, the first toggle wing 221 rotates in a counterclockwise direction and the second toggle wing 222 rotates in a clockwise direction. When the first toggle wing 221 and the second toggle wing 222 move towards the second end 214, the first sliding wing 251 and the second sliding wing 252 move towards the direction close to the linkage rod 210 under the driving of the guide column 223 of the toggle wing 220, and rotate along with the rotation of the first toggle wing 221 and the second toggle wing 222 until the second expansion piece 320 returns to the original state, at this time, the flipping mechanism 200 moves to the folded state 20, and the second expansion piece 320 is powered off. Through the above arrangement, the first sliding wing 251 and the second sliding wing 252 can drive the movable region 130 of the first display portion 110 and the movable region 130 of the second display portion 120 to move towards the direction close to the connecting region 140, so that the distance between the two movable regions 130 and the width of the two connecting regions 140 are always matched, and the damage caused by stretching deformation and uneven stress due to the switching of the states of the flipping mechanism 200 of the first display portion 110 and the second display portion 120 is avoided.

Of course, in other embodiments, it may also be: when turnover mechanism 200 is in folded state 20, first telescopic member 310 is in an original state and second telescopic member 320 is in a compressed state. When canting mechanism 200 is in deployed state 30, first telescoping member 310 is in a compressed state and second telescoping member 320 is in an original state. The first telescopic member 310 or the second telescopic member 320 is controlled to elongate until the first telescopic member 310 or the second telescopic member 320 returns to the initial state by changing the power-on and power-off conditions of the first telescopic member 310 and the second telescopic member 320, so as to control the turnover mechanism 200 to switch between the folding state 20 and the unfolding state 30.

It should be noted that the extending direction of the guiding groove 253 is related to the rotation direction of the toggle wing 220. For example, when the direction of the thread in the toggle wing 220 and the linkage rod 210 changes, i.e. when the first toggle wing 221 rotates counterclockwise in the process of moving from the second end 214 to the first end 213, the guide slot 253 on the sliding wing 250 extends in the direction from the first end 213 to the second end 214 toward the linkage rod 210, so as to ensure that the toggle wing 220 is far away from the linkage rod 210 when the flipping mechanism 200 is in the unfolded state 30, and the toggle wing 220 is close to the linkage rod 210 when the flipping mechanism 200 is in the folded state 20. Meanwhile, the angle between the guide groove 253 and the linkage rod 210 is related to the following factors: the thickness of first and

second brackets

150 and 160, the relative positional relationship of first and second linkage bars 211 and 212 to active area 130 and attachment area 140, and so forth. The included angle between the guide groove 253 and the linkage rod 210 is adjusted according to various factors to ensure that when the flipping mechanism 200 is in the folded state 20 or the unfolded state 30, both the first display part 110 and the second display part 120 can form a smooth or flat surface, so as to prevent the first display part 110 and the second display part 120 from stretching, folding and the like due to the switching of the states of the flipping mechanism 200. In this embodiment, the first toggle wing 221 and the second toggle wing 222 are both provided with two guide posts 223, and the first sliding wing 251 and the second sliding wing 252 are provided with two guide grooves 253 in a matching manner. Of course, in other embodiments, the number of the guide posts 223 and the guide grooves 253 may be 1, 3, or more than 3.

Further, the flipping mechanism 200 further includes a rotation guide 260, and the rotation guide 260 is rotatably connected to the linkage rod 210. In this embodiment, each of the first and second rotation supports 2401 and 2402 includes a first positioning portion 241 and a second positioning portion 242, and a gap for engaging the rotation guide 260 is provided in each of the first and

second positioning portions

241 and 242. The rotation guide 260 has a receiving groove 261, the receiving groove 261 extends along the radial direction of the linkage rod 210, and the sliding wing 250 can be slidably disposed in the receiving groove 261. The rotation guide 260 may be rotated by the sliding wing 250. Through the above arrangement, the rotation guide 260 guides the sliding of the sliding wing 250 toward or away from the linkage bar 210.

In addition, the electronic device 10 further includes a control module (not shown) electrically connected to the telescopic member 300, and the control module can change the length of the telescopic member 300 according to a user instruction, so as to enable the telescopic member 300 to respond to the user instruction and change the length thereof. The lengths of the first telescopic member 310 and the second telescopic member 320 are changed by the control module to switch the flipping mechanism 200 between the folded state 20 and the unfolded state 30. Of course, the user can also manually apply a force to the first display portion 110 and the second display portion 120 to switch the flipping mechanism 200 between the folded state 20 and the unfolded state 30.

The electronic device 10 may perform touch detection, thrust detection, and the like, the user instruction may include operations such as touching, pushing, and the like of the user on the first display portion 110 and the second display portion 120, and the control module may determine whether to change the length of the first extensible member 310 or the second extensible member 320 according to the user instruction, so as to drive the driving rod 310 to rotate, so as to assist the user in completing switching the state of the flipping mechanism 200, and further improve user experience. Alternatively, the user command further includes a voice control command issued by the user, such as related voice content of unfolding or folding, and the control module may determine whether to change the length of the first telescopic member 310 or the second telescopic member 320 according to the user command, so as to complete the switching of the state of the flipping mechanism 200.
