Referring to fig. 1 to 3 and fig. 9, as shown in the figures, the rotating shaft mechanism provided in the present application includes a shaft body 10, two rotating assemblies 20 symmetrically disposed at two ends of the shaft body 10, and two sliding members 30 oppositely disposed at two sides of the shaft body 10.

The two rotating assemblies 20 are symmetrically disposed at two ends of the shaft body 10, and for one rotating assembly 20 located at one end of the shaft body 10, the rotating assembly 20 includes two first connecting members 210 and a transmission unit 220. The two first connecting pieces 210 are oppositely arranged on two sides of the shaft body 10, and the two opposite first connecting pieces 210 are respectively connected to two sides of the transmission unit 220 and are in sliding connection with the transmission unit 220. During the relative movement to the middle of the two first connecting members 210, the movement directions of the two sides are coordinated through the transmission unit 220, and the distance and direction of the two first connecting members 210 sliding relative to the transmission unit 220 are kept consistent, so that the two first connecting members 210 can synchronously move to the middle of the shaft body from two sides, and during the movement, the movement modes of the two first connecting members 210 on the two sides of the shaft body 10 are symmetrical.

The two sliding members 30 are disposed oppositely and symmetrically on two sides of the shaft 10, and are correspondingly connected with the first connecting member 210 on the same side of the shaft 10 in a sliding manner. That is, for a sliding member 30, it is located at one side of the shaft body 10 and is slidably connected to the two first connecting members 210 located at the two ends of the shaft body 10, so that when the two first connecting members 210 at the side move towards the middle, the sliding member 30 is driven to move towards the middle through the sliding connection.

Further, please refer to fig. 4 to 6, and fig. 4 to 6 are schematic structural diagrams and exploded views of a part of the rotating assembly 20 in the rotating shaft mechanism according to an embodiment of the present application. As shown, the transmission unit 220 includes a first base 221 and a gear module 222. The first base 221 is fixed to the back of the shaft 10, and cooperates with the shaft 10 to form a first receiving space. The width of the first base 221 is adapted to the shaft 10, and the length thereof can be set according to actual needs, so as to construct a first accommodating space capable of accommodating the gear module 222. The gear module 222 is disposed in the first accommodating space. The gear module 222 includes two driving gears 2221 and two transmission gears 2222, the two driving gears 2221 are slidably connected to the two first connecting members 210, respectively, and the transmission gears 2222 are engaged between the two driving gears 2221. In the embodiment of the present application, the number of the transmission gears 2222 may be set according to actual needs, for example, according to the requirement of the rotation radian to be achieved by the rotating shaft mechanism, and the setting may be performed by referring to the conditions of the size parameter or the stress parameter of the gear, the width of the shaft body 10, or the required spacing between the two sliding members 30, and the like, which are not specifically limited herein. In this embodiment, the gear module 222 performs stress transmission through a plurality of gears, so that stress points are dispersed, and the service life of each part is prolonged. The gear module 222 is disposed on the first base 221 in the order of the driving gear 2221, the transmission gear 2222, and the driving gear 2221, and the two first connecting members 210 disposed opposite to each other are connected to the two driving gears 2221, so as to maintain synchronization during the movement toward the middle.

In some embodiments, in order to enable the first connecting member 210 to drive the sliding member 30 to open or close quickly, the transmission unit 220 further includes an elastic unit 223 and a pushing block 2232. The elastic unit 223 includes an elastic member 2231 disposed along the axial direction of the gear, and the elastic member 2231 is disposed in one-to-one correspondence with the driving gear 2221 and is compressed when a pressure is applied in the axial direction of the driving gear, so as to provide a restoring elastic force in the axial direction of the gear. Of course, when the transmission gears 2222 are also rotated, for example, when there are 2 transmission gears 2222, the transmission gears 2222 are rotated together with the driving gear 2221 on the same side, and at this time, the elastic member 2231 may be correspondingly arranged in the axial direction of the transmission gears 2222 to provide a larger elastic force value. The pushing block 2232 is located between the elastic unit 223 and the gear module 222, and a concave surface 2232a and a convex surface 2232b are provided on a surface of the pushing block 2232 opposite to the end surface of each gear. The end surface of each driving gear 2221 in the gear module 222 is provided with a corresponding projection 22211, and the end surface of the transmission gear 2222 can be provided with a corresponding projection 22211 according to actual needs. When the convex portion 22211 corresponds to the convex surface 2232b during the transmission process of the gear module 222, the pushing block 2232 can be pushed to move towards the elastic unit 223, so as to compress the elastic unit 223; when the protruding portion 22211 is away from the convex surface 2232b, the pushing block 2232 moves toward the gear module 222 under the action of the restoring elastic force generated after the elastic unit 223 is compressed, so that the concave surface 2232a and the protruding portion 22211 can be suddenly and rapidly pushed against each other under the pushing action of the restoring elastic force, and the driving gear 2221 is driven to rapidly move, so that the sliding member 30 is rapidly driven to open or close through the first connecting member 210, which is beneficial to improving user experience.

In some embodiments, the driving gear 2221 is provided with a connecting portion 22212 to be slidably connected with the first connecting member 210 through the connecting portion 22212. A first opening 211 is formed in the first connecting member 210, and two first clamping grooves 211a are formed in two opposite edges in the first opening 211; the end of the connecting portion 22212 may extend into the first opening 211, and two sides of the end of the connecting portion 22212 may be fittingly engaged with the first engaging groove 211a and may slide in the first engaging groove 211a along the direction of the engaging groove, so as to avoid interference with the driving gear 2221 when the first connecting member 210 moves towards the middle.

Since the sliding member 30 is used to drive the first screen portion and the second screen portion to move, in order to further limit the position of the sliding member 30 during the moving process, a first limiting portion 31 is disposed on the sliding member 30, as shown in fig. 10 and 11. Meanwhile, in order to be matched with the first limiting part 31, a second opening 22212a is formed in the end of the connecting part 22212, and a first pin 22212b is arranged in the second opening 22212 a; the first pin 22212b is inserted into the first position-limiting portion 31, and the first pin 22212b can slide in the first position-limiting portion 31 according to the movement track of the first sliding member 30 relative to the transmission unit 220. In this embodiment, the first position-limiting part 31 is matched with the first pin 22212b, so that the distance between the sliding member 30 and the transmission unit 220 can be limited, and the movement position of the position-limiting part can be further controlled. Here, the shape, size, and arrangement of the first position-limiting portion 31 may be set according to actual requirements, and may accommodate the first pin 22212b to be inserted therein, and guide the sliding track of the first pin 22212b according to requirements, which is not limited herein.

In some embodiments, in order to guide the sliding member 30 to slide relative to the first connecting member 210, a first arc-shaped sliding slot 212 is disposed on an outer side of the first connecting member 210, and the first arc-shaped sliding slot 212 matches with a sliding track of the sliding member 30 relative to the first connecting member 210. The sliding member 30 is provided with a first sliding block 33 capable of being accommodated in the first arc-shaped sliding chute 212, so as to guide the movement track of the first sliding block 33 through the first arc-shaped sliding chute 212. When the first connecting element 210 moves, the first sliding block 33 slides in the first arc-shaped sliding chute 212, so that the sliding element 30 is driven to move correspondingly.

In some embodiments, to further stabilize the connection of the first connecting element 210, the rotating assembly 20 further includes two oppositely disposed first connecting rods 230, which are arranged corresponding to the first connecting element 210, so as to connect the first connecting element 210 with the shaft body 10. One end of the first link 230 is rotatably connected to the first connecting element 210 on the same side of the shaft body 10, and the other end of the first link is rotatably connected to the shaft body 10. In some specific embodiments, as shown in fig. 13, one end of the first link 230 may be provided with a through hole 232, and correspondingly, the first link 210 is provided with a pin shaft 212, and the pin shaft 212 is inserted into the through hole 232 and can rotate in the through hole 232, so that the first link 230 can rotate relative to the first link 210. The first receiving space is provided with a semi-cylindrical protrusion on the shaft body 10 to form the rotation connecting shaft 11, and the other end of the first link 230 is formed with an arc-shaped structure 231 fitted to the rotation connecting shaft 11. After the other end of the first connecting rod 230 extends into the first accommodating space, the arc-shaped structure 231 is wrapped on the rotating connecting shaft 11 and can rotate around the rotating connecting shaft 11, so that the first connecting rod 230 is connected to the shaft body 10 and can rotate relative to the shaft body 10.

In some embodiments, in order to further improve the folding effect, and also to allow for the screen near the middle of the shaft 10, especially the screen near the shaft 10, to be recessed when the user performs a clicking or pressing operation after the screen of the electronic device is opened, the hinge mechanism further includes a supporting component 40, as shown in fig. 7 and 8. The supporting component 40 is located in the middle of the shaft body 10 to support the shaft body 10, so that the screen is prevented from being sunk. The supporting assembly 40 includes two pairs of second connecting members 410 disposed at two sides of the shaft body 10, and the second connecting members 410 are rotatably connected to the shaft body 10 and slidably connected to the sliding member 30 located at the same side of the shaft body 10. In some specific application modes, two second connecting members 410 are respectively disposed on the first housing portion 51 and the second housing portion 52, so that when the housing 50 moves from the folded state to the unfolded state, the second connecting members 410 drive the sliding member 30 to move towards two sides in the process of moving from the middle of the shaft 10 towards two sides, thereby improving the folding effect. Meanwhile, in the opened state, the second link may also support the middle portion of the sliding member 30, so that the sliding member 30 can support the first screen portion and the second screen portion connected thereto to prevent the middle of the screen from being depressed.

In some embodiments, the supporting assembly 40 further includes a second base 420 and two second connecting rods 430 oppositely disposed on two sides of the shaft body 10.

In this embodiment, the connection manner between the second link 430 and the second connector 410 may refer to the connection manner between the connection portion 22212 of the driving gear 2221 and the first connector 210, so that one end of the second link 430 is engaged with the second connector 410 through a snap-fit relationship, thereby achieving the sliding connection between the second link 430 and the second connector 410. In some embodiments, the second connector 410 is provided with a third opening 411, and two second locking grooves 412 are provided on two opposite sides of the third opening 411. One end of the second connecting rod 430 extends into the third opening 411, and two sides of the second connecting rod 430 are fittingly engaged with the second engaging groove 412 and can slide in the second engaging groove 412, so as to avoid interference with the second connecting rod 430 when the second connecting member 410 moves toward the middle.

A cylindrical pin rod (not shown) may be disposed at the other end of the second link 430 through a through hole (not shown), and the shape and size of the second receiving space are adapted to the shape of the pin rod, so as to receive the pin rod, so that the first link 230 is connected to the shaft body 10 and can rotate relative to the shaft body 10.

In some embodiments, referring to fig. 10 and 12, a fourth opening 431 is formed at one end of the second connecting rod 430, a second pin 432 is disposed in the fourth opening 431, and a second limiting portion 32 is disposed on the sliding member 30; the second pin 432 is disposed through the second position-limiting portion 32 and can slide in the second position-limiting portion 32. In this embodiment, the arrangement and the matching manner of the second pin 432 and the second position-limiting portion 32 may refer to the implementation manner of the first pin 22212b and the first position-limiting portion 31, and are not described herein again.

In some embodiments, the second connecting member 410 is provided with a second arc-shaped sliding slot 413 on both sides, and the second arc-shaped sliding slot 413 matches with the sliding track of the sliding member 30 relative to the first connecting member 210. A second sliding block 34 capable of being accommodated in the second arc-shaped sliding groove 413 is arranged at a corresponding position on the sliding member 30, so that the movement track of the first sliding block 33 is guided through the second arc-shaped sliding groove 413. When the second connecting member 410 moves, the second sliding block 34 slides in the second arc-shaped sliding groove 413, so that the second connecting member 410 can drive the sliding member 30 to move.

In some embodiments, the first link 210 and the second link 410 are configured as an inclined plane on the side facing the slider 30, and the inclined plane is inclined from the first link 210 or the second link 410 to the shaft 10 and gradually moves away from the slider 30; when the two sliding members 30 are folded over the shaft body 10, a drop-shaped bottom space is formed by the inclined surfaces. In this embodiment, the movement patterns of the shaft body 10 on the left and right sides are symmetrical, and the movement pattern on one side will be described as an example. When the housing 50 moves from the opened state to the folded state, the first housing portion 51 moves toward the middle, and the two first connecting members 210 and the second connecting members 410 disposed on the first housing portion 51 rotate from two sides of the shaft body 10 toward the middle, so as to drive the corresponding sliding members 30 to move to the middle of the shaft body 10, and under the guiding action of the arc-shaped sliding grooves, the sliding members 30 abut against the inclined surfaces of the first connecting members 210 and the second connecting members 410.
