As shown in fig. 3 to 5, the flipping mechanism 200 includes a linkage rod 210 and a toggle wing 220, and the toggle wing 220 is sleeved on the linkage rod 210 and is in threaded connection with the linkage rod 210. In this embodiment, the toggle wing 220 includes a first toggle wing 221 and a second toggle wing 222, the first toggle wing 221 is coupled to the first display portion 110, and the second toggle wing 222 is coupled to the second display portion 120. The first toggle wing 221 and the second toggle wing 222 can rotate relatively to drive the first display portion 110 and the second display portion 120 to rotate relatively. With the above arrangement, independent movement of the first display part 110 and the second display part 120 can be realized, and the display mechanism 100 can be quickly positioned by controlling the movement of the first display part 110 and the second display part 120 at the same time. Of course, in other embodiments, the toggle wing 220 may be only coupled to the first display portion 110 or only coupled to the second display portion 120, so as to drive one of the first display portion 110 and the second display portion 120 to rotate relative to the other.

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 a non-zero included angle with the axial direction of the linkage rod 210, so that the sliding wing 250 can move towards or away from the linkage rod 210, and the sliding wing 250 can drive the dial wing 220 to move relative to the linkage rod 210.

In this embodiment, the sliding wing 250 includes 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 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 portion of the first display portion 110 and the second display portion to move towards or away from the linkage rod 210.

Referring to fig. 2, the driving mechanism 300 is fixedly disposed on the sliding wing 250, and the driving mechanism 300 can respond to a user command and drive the guide post 223 to slidably disposed in the guide groove 253, so as to drive the toggle wing 250 to move along the axial direction of the linkage rod and rotate along the radial direction of the linkage rod.

The drive mechanism 300 includes a drive rod 310, a driver, and a drive block 320. Drives the rod 310. Wherein the driving rod 310 is threaded with its axis parallel to the guide groove 253. The driver is connected with the driving rod 310, can respond to a user command, and drives the driving rod 310 to rotate. The driving block 320 is threadedly coupled to the driving rod 310 and forms a screw pair. The driving block 320 is connected with the guide post 253 and drives the sliding wing 250 and the toggle wing 220 to cooperatively move along the axial direction of the linkage rod 210, so that the sliding wing 250 and the toggle wing 220 rotate along the radial direction of the linkage rod 210.

Through the above arrangement, when the electronic device 10 receives a folding or closing instruction and other related instructions sent by a user, the driving mechanism 300 can drive the turning mechanism 200 to operate, so as to drive the first display part 110 and the second display part 120 to rotate relatively, thereby realizing the automatic change of the form of the electronic device, being convenient and fast to operate, and avoiding the problems of complexity, improper turning and the like caused by manual operation.

In this embodiment, at least a portion of the guide posts 223 form the drive block 320 described above. Of course, the driving block 320 and the guide post 223 may be separate components that are fixedly connected only during use.

The driver is a motor 330, the motor 330 is fixedly connected to the sliding wing 250, and the motor 330 is connected to the driving rod 310 to drive the driving rod 310 to rotate, so as to drive the driving block 320 to move. The driving rod 310 is provided directly above the guide groove 253. When the motor 330 drives the driving rod 310 to rotate, the driving rod 310 can drive the guide posts 223 to move synchronously. The guide posts 223 are slidably disposed in the guide grooves 253. Because of the non-zero included angle formed between the guide groove 253 and the axial direction of the linkage rod 210, the component of the axial movement of the guide post 223 in the driving mechanism 300 along the parallel linkage rod 210 can drive the dialing wing 220 to move along the axial direction of the linkage rod 210. The toggle wing 220 is connected to the linkage rod 210 by a screw, so the toggle wing 220 can drive the sliding wing 250 to rotate radially relative to the linkage rod 210. The motion component of the guide post 223 in the driving mechanism 300 along the direction perpendicular to the axial direction of the linkage rod 210 can drive the sliding wing 250 to move towards or away from the linkage rod 210. By controlling the movement of the sliding wing 250, particularly, at least a part of the display mechanism 100 can move towards a direction close to or away from the linkage rod 210, when the display mechanism 100 moves along with the toggle wing 220, the part of the display mechanism 100 far from the linkage rod 210 cannot squeeze the part close to the linkage rod 210, so that the situation that a flexible display screen in the display mechanism 100 is wrinkled or stressed unevenly is avoided, and the display mechanism 100 is protected.

Of course, in other embodiments, the guide posts 223 and the driving block 320 may be separate components, and they may be bonded, snapped, or otherwise connected to form a single unit when in use. When the motor 330 drives the driving rod 310 to rotate, the driving rod 310 can drive the driving block 320 and the guide post 223 to move synchronously.

The first drive rod 311 and the first drive block 321 form one helical pair, and the first drive rod 312 and the second drive block 322 form another helical pair.

The first motor 331, the first driving rod 311 and the first driving block 321 cooperate to control the first sliding wing 251 and the first dial wing 221 to move along the axial direction of the first linkage rod 211 to a direction close to the first end 213 or close to the second end 214, and rotate along the radial direction of the first linkage rod 211. The second motor 332, the second driving rod 312 and the second driving block 322 cooperate to control the second sliding wing 252 and the second moving wing 222 to move along the axial direction of the second linkage rod 212 to a direction close to the first end 213 or close to the second end 214, and to rotate along the radial direction of the second linkage rod 212. In this embodiment, the number of the guide grooves 253 formed in the first sliding wing 251 and the second sliding wing 252 is two, the two guide grooves 253 on the first sliding wing 251 are parallel to each other, the two guide grooves 253 on the second sliding wing 252 are parallel to each other, and the guide grooves 253 on the first sliding wing 251 and the guide grooves 253 on the second sliding wing 252 are symmetrically arranged. Correspondingly, the number of the guide posts 223 on the first toggle wing 221 and the second toggle wing 222 is two. 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.

second dial wings

221 and 222 and the synchronous movement of the first and second sliding

wings

251 and 252.

It should be noted that, the synchronous movement of the first toggle wing 221 and the second toggle wing 222 is referred to herein as the movement of the first toggle wing 221 and the second toggle wing 222 toward the first end 213 or the second end 214 at the same speed, and the rotation along the radial direction of the linkage rod 210 in the same rotation and the opposite direction.

Through the above arrangement, the two first motors 331 and the two second motors 332 can make the toggle wings 220 move synchronously in all directions and be stressed uniformly. Meanwhile, the first motor 331 and the second motor 332 can use motors with smaller power and size to provide power, so that the thickness of the electronic device 10 is reduced, and the electronic device 10 is light and thin.

The flipping mechanism 200 further includes a rotation bracket and a rotation guide 260.

The rotation guide 260 is rotatably coupled to the linkage bar 210. 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.

The rotating bracket further includes a third rotating bracket 2403, and the third rotating bracket 2403 is disposed in the first toggle wing 221 and the second toggle wing 222. In order to reduce the weight of the first dial wing 221 and the second dial wing 222 and to achieve a light and thin design of the electronic device 10, a hollow portion 224 may be disposed at a position of the first dial wing 221 and the second dial wing 222 where the linkage rod 210 is connected. The third rotating bracket 2403 disposed in the first and

second toggle wings

221 and 222 may be disposed in the hollow portion 224 and sleeved on the first and

second linkage rods

211 and 212 to support the first and

second linkage rods

211 and 212. It should be noted that the third rotation bracket 2403 provided in the first toggle wing 221 and the second toggle wing 222 cannot interfere with the movement of the first toggle wing 221 and the second toggle wing 222.

As shown in conjunction with fig. 1, 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 connection with fig. 1, 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 252, so as 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 towards 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. 4 and 5, the flipping mechanism 200 is switchable between the folded state 20 and the unfolded state 30.

As shown in fig. 4, when necessary in conjunction with fig. 1 to 3, when the flipping mechanism 200 is in the folded state 20, the active areas 130 of the first display portion 110 and the second display portion 120 are disposed opposite to each other, and the plane of the active areas 130 of the first display portion 110 and the plane of the active areas 130 of the second display portion 120 are parallel, and the plane of the active areas 130 is perpendicular to the plane of the connecting areas 140. That is, the first toggle wing 221 and the second toggle wing 222 are disposed opposite to each other, and planes on which the two toggle wings are disposed are parallel to each other; the first sliding wing 251 and the second sliding wing 252 are disposed opposite to each other, and planes of the first sliding wing 251 and the second sliding wing 252 are parallel to each other. The first toggle wing 221 and the second toggle wing 222 are proximate the second end 214. 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. 5, when necessary in conjunction with fig. 1 to 3, when the flipping mechanism 200 is in the unfolded state 30, the plane on which the first display portion 110 is located and the plane on which the second display portion 120 is located coincide, and the upper surfaces of the first display portion 110 and the second display portion 120 are connected to form a flat surface. That is, the first toggle wing 221 and the second toggle wing 222 are arranged in parallel, and planes on which the two toggle wings are located are overlapped; the first sliding wing 251 and the second sliding wing 252 are disposed in parallel, and the planes of the first sliding wing 251 and the second sliding wing 252 coincide with each other. 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 proximate the first end 213. 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.

As shown in fig. 1 to fig. 5, when the flipping mechanism 200 is switched from the folded state 20 to the unfolded state 30, the first motor 331 and the second motor 332 are electrically rotated to drive the driving rod 310 to rotate, the driving block 320 drives the guiding column 223 to move towards the direction close to the first end 213, and slide towards the direction close to the linkage rod 210 relative to the sliding wing 250, so that the first toggle wing 221 and the second toggle wing 222 move towards the direction close to the first end 213, and the toggle wing 220 is sleeved on the linkage rod 210, so the first toggle wing 221 and the second toggle wing 222 respectively drive the first sliding wing 251 and the second sliding wing 252 to move towards the direction far away from the first linkage rod 211 and the second linkage rod 212. While 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, the first toggle wing 221 rotates in the clockwise direction, and the second toggle wing 222 rotates in the 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 respectively drive the first bracket 150 and the second bracket 160 to move synchronously towards the direction far 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 toggle wing 221 and the second toggle wing 222 move in place and the flipping mechanism 200 moves to the unfolding state 30. Through the above arrangement, the first sliding wing 251 and the second sliding wing 252 can respectively drive the movable region 130 of the first display part 110 and the movable region 130 of the second display part 120 to move towards the direction far away from the connecting region 140 through the first bracket 150 and the second bracket 160, so that the distance between the two movable regions 130 is matched with the width of the two connecting 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 first motor 331 and the second motor 332 are powered to rotate in opposite directions to drive the driving rod 310 to rotate, the driving block 320 drives the guiding post 223 to move in a direction close to the second end 214 and slide in a direction away from the linkage rod 210 relative to the sliding wing 250, so that the first toggle wing 221 and the second toggle wing 222 move in a direction close to the second end 214, and the toggle wing 220 is sleeved on the linkage rod 210, so that the first toggle wing 221 and the second toggle wing 222 respectively drive the first sliding wing 251 and the second sliding wing 252 to move in a direction close to the first linkage rod 211 and the second linkage rod 212. 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 at the same time, the first toggle wing 221 rotates in the counterclockwise direction and the second toggle wing 222 rotates in the 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 respectively drive the first bracket 150 and the second bracket 160 to 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 first toggle wing 221 and the second toggle wing 222 move in place and the flipping mechanism 200 moves to the folded state 20. Through the above arrangement, the first sliding wing 251 and the second sliding wing 252 can respectively drive the movable region 130 of the first display part 110 and the movable region 130 of the second display part 120 to move towards the direction close to the connection region 140 through the first bracket 150 and the second bracket 160, so that the distance between the two movable regions 130 and the width of the two connection regions 140 are always matched, and the damage caused by stretching deformation and uneven stress in the first display part 110 and the second display part 120 due to the switching of the state of the flipping mechanism 200 is avoided.

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 and the driving rod 310 extend in the direction from the first end 213 to the second end 214 to approach 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.

The electronic device 10 further includes a control module (not shown) electrically connected to the driving mechanism 300 to control the operation of the driving mechanism 300.

In this embodiment, the control module is electrically connected to the first motor 331 and the second motor 332, and controls the rotation speed and the rotation direction of the first motor 331 and the second motor 332. The rotation speed and the rotation direction of the first motor 331 and the second motor 332 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 can perform touch detection, thrust detection, and the like, and the control module detects operations such as touch and pushing of the user on the first display portion 110 and the second display portion 120 to determine whether to change the rotation speed and the rotation direction of the first motor 331 and the second motor 332, so as to assist the user in completing switching of the state of the flipping mechanism 200, and further improve user experience. Alternatively, the electronic device 10 may also detect a control command issued by the user, such as a related voice content of unfolding or folding, and the control module determines whether to change the rotation speed and the rotation direction of the first motor 331 and the second motor 332, so as to complete the switching of the state of the flipping mechanism 200.
