However, when the above-mentioned folding screen terminal 01 is subjected to a large impact force, it is easy to cause further relative sliding between the swing arm 200 and the door panel 300 at the extreme position, thereby affecting the reliability of other components, or directly causing damage to other components. . It should be noted that the extreme position between the swing arm 200 and the door panel 300 refers to the relative position between the swing arm 200 and the door panel 300 when the folding screen terminal 01 is in the above-mentioned unfolded state or folded state.

For example, please continue to refer to FIG. 6 . When the folding screen terminal 01 is in the above folded state, when the folding screen terminal 01 falls, the door panel 300 and the swing arm 200 will move toward each other, that is, the door panel 300 Sliding in the direction close to the center beam 100 (shown in the direction A in Figure 6), due to the large impact force, the relative position of the door panel 300 and the swing arm 200 will exceed the limit position, causing the door panel 300 to drive the first housing 21 and the first housing 21. When the second housing 22 and the folding screen 10 move toward the center beam 100 , the folding screen 10 may be easily squeezed, which may cause the folding screen 10 to fail.

Moreover, when the folding screen terminal 01 rebounds after falling to the ground, since the swing arm 200 is connected to the center beam 100, the door panel 300 will slide in a direction away from the center beam 100 (that is, the opposite direction of the direction A in Figure 6), which may As a result, the door panel 300 and the swing arm 200 are separated from each other, resulting in the failure of the rotating shaft mechanism 23 and affecting the rotation of the folding screen terminal 01 to the unfolded state.

Alternatively, please refer to FIG. 7 , which is a cross-sectional structural view of a rotating shaft mechanism 23 in a deployed position according to an embodiment of the present application. When the folding screen terminal 01 is in the above unfolded state, that is, the rotating shaft mechanism 23 is in the unfolded position, during use, when the user squeezes the terminal along both sides of the X-axis direction, the door panel 300 and the swing arm 200 will Sliding in the direction of approaching each other, that is, the door panel 300 drives the first housing 21 and the second housing 22 shown in FIG. 2 to move closer to the center beam 100 (shown in the direction B in FIG. 7 ), which will cause the folding screen 10 Arching along the Z-axis direction (shown in the C direction in Figure 7) may cause the folding screen 10 to fail.

To solve the above problem, please refer to Figures 8, 9 and 10. Figure 8 is an assembly diagram of another rotating shaft mechanism 23 provided by an embodiment of the present application. Figure 9 is an assembly diagram of another rotating shaft mechanism 23 provided by an embodiment of the present application. Exploded view, Figure 10 is a partial structural view of the rotating shaft mechanism 23 provided in Figures 8 and 9, and the dotted lines in Figure 10 represent the internal structure. The rotating axis mechanism 23 can be applied to the folding screen terminal 01 shown in FIGS. 1 to 3 . The rotating axis mechanism 23 can include the above-mentioned center beam 100 , swing arm 200 , door panel 300 and limiting member 400 .

Specifically, swing arms 200 and door panels 300 are provided on both sides of the center beam 100 (along the Y-axis direction), and multiple swing arms 200 can be provided between the door panel 300 and the center beam 100 at intervals along the Y-axis direction. One end of 200 is rotationally connected to the center beam 100, and the swing arms 200 located on both sides of the center beam 100 rotate in opposite directions, so that the folding screen terminal 01 can rotate between the folded state and the unfolded state.

For example, the rotational connection between the plurality of swing arms 200 and the center beam 100 may adopt the same connection method, or may adopt different connection methods. For example, the swing arm 200 and the center beam 100 can be connected by an arc-shaped groove and an arc-shaped slider, so that the swing arm 200 can rotate along the arc-shaped groove relative to the center beam 100; or, between the swing arm 200 and the center beam 100 The rotational connection can also be achieved by matching the rotating shaft and the shaft hole, and the swing arms 200 on both sides of the center beam 100 can be meshed through a gear set, so that the swing arms 200 on both sides of the center beam 100 can rotate synchronously and in opposite directions. . Therefore, this application does not impose special limitations on this.

The door panel 300 is provided with a chute 321 (shown as a dotted line in FIG. 10 ), and the end of the swing arm 200 away from the center beam 100 is inserted into the chute 321 so that the swing arm 200 is slidably connected to the door panel 300 . The sliding direction between the swing arm 200 and the door panel 300 is perpendicular to the rotation axis of the rotational connection between the swing arm 200 and the center beam 100 . For example, the rotation axis of the swing arm 200 relative to the center beam 100 may be parallel to the Y-axis direction, and the sliding direction between the swing arm 200 and the door panel 300 may be perpendicular to the Y-axis direction.

The swing arm 200 is provided with a first limit hole 210 , and the door panel 300 is provided with a second limit hole 322 . The axes of the first limit hole 210 and the second limit hole 322 are along the axis of the door panel 300 and the swing arm 200 . The stacking direction is set, and the first limiting hole 210 penetrates both sides of the swing arm 200 , the second limiting hole 322 penetrates the surface of the door panel 300 , and the second limiting hole 322 is connected with the slide groove 321 . The first limiting hole 210 and the second limiting hole 322 both extend in a direction perpendicular to the stacking direction of the door panel 300 and the swing arm 200 (that is, the first limiting hole 210 and the second limiting hole 322 both extend along the radial direction of the door panel 300 and the swing arm 200 ). extend), so that the first limit hole 210 and the second limit hole 322 both form elongated through holes, and the first limit hole 210, the second limit hole 322, the swing arm 200 and the door panel 300 slide relatively The sliding directions intersect in pairs.

Please continue to refer to FIG. 8 , FIG. 9 and FIG. 10 . The above-mentioned limiting member 400 can pass through the first limiting hole 210 and the second limiting hole 322 in sequence along the stacking direction of the door panel 300 and the swing arm 200 , that is, the limiting member 400 It is located at the intersection of the first limiting hole 210 and the second limiting hole 322 . When the door panel 300 rotates with the swing arm 200 relative to the center beam 100, the door panel 300 and the swing arm 200 slide relative to each other, and the limiter 400 slides relative to the swing arm 200 along the extension direction of the first limit hole 210, and the limiter The positioning member 400 slides relative to the door panel 300 along the extending direction of the second limiting hole 322 .

For example, please continue to refer to FIG. 10 . The limiting member 400 may be a limiting rod 410 or a pin. In this embodiment, the limiting member 400 is a limiting rod 410 for illustration. 410 is parallel to the axes of the first limiting hole 210 and the second limiting hole 322 .

Furthermore, the first limiting hole 210 has a first end 210a and a second end 210b along its extending direction, and the second limiting hole 322 has a third end 322a and a fourth end 322b along its extending direction. Along the sliding direction in which the swing arm 200 and the door panel 300 slide relative to each other, the first end 210a and the third end 322a are located on the same straight line, and the second end 210b and the fourth end 322b are located on the same straight line. That is, the line connecting the first end 210a and the third end 322a is parallel to the sliding direction between the swing arm 200 and the door panel 300, and the line connecting the second end 210b and the fourth end 322b is parallel to the swing arm 200 and the door panel 300. The sliding direction between them is parallel.

When the folding screen terminal 01 is in an unfolded state (as shown in FIGS. 1 and 2 ), that is, the swing arm 200 and the door panel 300 are in the unfolded position as shown in FIG. 8 . Please refer to Figure 11. Figure 11 is a structural diagram of the relative position between the swing arm 200 and the door panel 300 of the rotating shaft mechanism 23 (in the unfolded position) provided in Figure 8. It is parallel to the extension direction of the first limiting hole 210 and parallel to On the plane in the extending direction of the second limiting hole 322, the vertical projections of the first end 210a of the first limiting hole 210 and the third end 322a of the second limiting hole 322 coincide with each other, and the limiting rods 410 pass through them in sequence. Passing through the first end 210a and the third end 322a, that is, the limiting rod 410 is located at one end of the first limiting hole 210 and the second limiting hole 322.

In this state, the door panel 300 moves toward the center beam 100 to the extreme position. When the terminal is squeezed from both sides to the middle along the X-axis direction, the limit rod 410 is at the first end 210a and the third end. 322a, therefore, the door panel 300 cannot slide further in the direction closer to the center beam 100. Therefore, the first housing 21 and the second housing 22 can be prevented from being squeezed inward, thereby preventing the folding screen 10 from arching upward to protect the The folding screen 10 is intact to avoid failure of the folding screen 10 .

During the rotation of the folding screen terminal 01 from the unfolded state to the folded state, the door panel 300 and the swing arm 200 move away from each other, that is, the door panel 300 moves away from the center beam 100 shown in Figure 8 (as shown in Figure 11 D1 direction) slide. Since the extending direction of the first limiting hole 210 , the extending direction of the second limiting hole 322 and the sliding direction of the door panel 300 and the swing arm 200 relative sliding intersect, that is, the extending direction of the first limiting hole 210 and the second limiting hole 210 intersect. The extension direction of the position holes 322 is inclined relative to the sliding direction of the door panel 300 . Therefore, when the door panel 300 slides relative to the swing arm 200, the limiting rod 410 can receive a component force along the extending direction of the first limiting hole 210 and the second limiting hole 322, so that the limiting rod 410 moves relative to the swing arm 200. The arm 200 moves from the first end 210a to the second end 210b (as shown in the D2 direction in FIG. 11 ), and the limiting rod 410 moves from the third end 322a to the fourth end 322b relative to the door panel 300 (such as As shown in the D3 direction in Figure 11).

When the above-mentioned folding screen terminal 01 is rotated to the folded state, that is, the swing arm 200 and the door panel 300 are in the folded position, please refer to Figures 12 and 13. Figure 12 is an assembly diagram of the rotating shaft mechanism 23 provided in Figure 8 in the folded position. FIG. 13 is a structural diagram of the relative position between the swing arm 200 and the door panel 300 of the pivot mechanism 23 (in a folded state) provided in FIG. 8 . On a plane parallel to the extending direction of the first limiting hole 210 and parallel to the extending direction of the second limiting hole 322 , the second end 210 b of the first limiting hole 210 and the fourth end of the second limiting hole 322 The vertical projections of the end portions 322b coincide with each other, and the limiting rod 410 passes through the second end portion 210b and the fourth end portion 322b in sequence, that is, the limiting rod 410 is at the other end of the first limiting hole 210 and the second limiting hole 322 Ends.

In this state, the door panel 300 moves in the direction away from the center beam 100 to the extreme position, and the door panel 300 cannot slide further away from the center beam 100 , thereby preventing the door panel 300 and the swing arm 200 from being separated from each other, which is beneficial to Improve the overall reliability of the rotating shaft mechanism 23.

It can be understood that the above embodiment is only one possible example. In other possible examples, it may also be that when the folding screen terminal 01 is in the unfolded state, the door panel 300 moves to the extreme position away from the center beam 100, and the door panel 300 moves to the limit position away from the center beam 100. The position lever 410 is located at the second end 210b and the fourth end 322b; when the folding screen terminal 01 is in the folded state, the door panel 300 moves to the extreme position close to the center beam 100, and the limit lever 410 is located at the first end. 210a and third end 322a. Therefore, this application does not impose special limitations on this.

Based on this, when the folding screen terminal 01 provided by the embodiment of the present application is in the unfolded state or the folded state, the limit rod 410 passes through the first limit hole 210 and the second limit hole 322 in sequence, so that the swing arm 200 and the door panel can be aligned. 300 forms a limit, which can reduce the risk of further relative sliding between the door panel 300 and the swing arm 200 when the terminal is impacted.

Moreover, when the folding screen terminal 01 is in the unfolded state or the folded state, the intersection between the first limiting hole 210 and the second limiting hole 322 is located at the end, that is, the limiting rod 410 is between the first limiting hole 210 and the second limiting hole 322 . The ends of the two limiting holes 322. In this way, since the limiting rod 410 is located at one end of the first limiting hole 210 and the second limiting hole 322 (for example, the limiting rod 410 is located at the first end 210a and the third end 322a), That is, at this time, the limiting rod 410 can only slide toward the other ends of the first limiting hole 210 and the second limiting hole 322 (ie, the above-mentioned second end 210b and the fourth end 322b). Therefore, the door panel 300 can be prevented from being moved. Further relative sliding between the door panel 300 and the swing arm 200 at the extreme position is beneficial to further reducing the risk of excessive sliding and extrusion or mutual separation between the door panel 300 and the swing arm 200 .

In some embodiments, please refer to FIG. 14 , which is an exploded view of a door panel 300 provided by an embodiment of the present application. The door panel 300 may include a panel body 310 and a connecting block 320 . The panel body 310 is used with the above-mentioned FIG. 1 Fixedly connected to the first housing 21 and the second housing 22 shown in Figure 2, the connecting block 320 is fixed on one side surface of the board body 310, and the other side surface of the board body 310 is used to support Figures 1 and 2. The folding screen 10 shown in 2. The connecting block 320 is located on the side of the swing arm 200 away from the center beam 100. The above-mentioned chute 321 is opened on the surface of the connecting block 320 facing the center beam 100. The end of the swing arm 200 away from the center beam 100 is inserted into the chute 321 to realize the swing arm. 200 is slidingly connected with the connecting block 320.

Also, please refer to FIG. 15 , which is an enlarged view of the partial structure diagram of the board body 310 provided in FIG. 14 . Along the stacking direction of the swing arm 200 and the connecting block 320 (that is, the stacking direction of the swing arm 200 and the door panel 300), second limiting holes 322 are opened on the two opposite inner walls of the chute 321, as shown in Figure 10 The limiting member 400 passes through the first limiting hole 210 and the two second limiting holes 322. Under this structure, the force balance of the limit rod 410 can be ensured during the relative sliding process of the swing arm 200 and the door panel 300, so that the limit rod 410 can move more smoothly along the first limit hole 210 and the second limit hole 210. The extension direction of the limiting hole 322 slides.

In some examples, at least one of the two second limiting holes 322 located on both sides of the slide groove 321 runs through the surface of the inner wall of the connecting block 320 away from the slide groove 321 along its axial direction, so as to facilitate the positioning of the limiting rod 410 by The outer side of the connecting block 320 is inserted into the second limiting hole 322 and passes through the first limiting hole 210 on the swing arm 200 and the second limiting hole 322 on the other side of the slide groove 321 in sequence, thereby reducing the installation difficulty.

For example, the second limiting hole 322 of the two second limiting holes 322 on the side away from the plate body 310 can be made to penetrate the side surface of the connecting block 320 away from the plate body 310 along its axial direction. In this way, during the production process, whether the connecting block 320 is connected to the plate body 310 first, and then the limiting rod 410 is inserted to connect the connecting block 320 to the swing arm 200; or the limiting rod 410 is inserted first to connect the connecting block 320 to the swing arm 200. Connecting the arm 200 and then connecting the connecting block 320 to the board body 310 will not affect production, which will help reduce assembly difficulty and improve production efficiency.

Alternatively, please continue to refer to FIG. 15 , the two second limiting holes 322 may both extend along the axial direction and penetrate both side surfaces of the connecting block 320 . In this way, the limiting rod 410 can be inserted from any side surface of the connecting block 320 to connect the connecting block 320 with the swing arm 200 , which is beneficial to further reducing assembly difficulty and improving production efficiency.

On this basis, in order to further improve the reliability of the limit rod 410 in forming a position limit between the door panel 300 and the swing arm 200 . Please refer to Figures 16 and 17. Figure 16 is a structural diagram of the connecting block 320 and the swing arm 200 of another rotating shaft mechanism 23 provided by the embodiment of the present application when they are in the unfolded position. Figure 17 is a structural diagram of the connecting block 320 and the swing arm 200 provided in Figure 16. Structural diagram of the swing arm 200 in the folded position. The rotating shaft mechanism 23 may also include a limiting part 500. The limiting part 500 is disposed in at least one of the first limiting hole 210 and the second limiting hole 322. That is, the limiting part 500 may be disposed in the third limiting hole. The limiting portion 500 can also be provided in the first limiting hole 210 and the second limiting hole 322 . The limiting portion 500 can also be provided in both the first limiting hole 210 and the second limiting hole 322 . In the following embodiments, the limiting part 500 is disposed in the second limiting hole 322 as an example for description.

The above-mentioned limiting part 500 is provided at the end of the second limiting hole 322. When the above-mentioned limiting rod 410 is located at one end of the second limiting hole 322 (for example, the fourth end 322b shown in FIG. 10) downward, the limiting part 500 is in contact with the limiting rod 410, and the limiting part 500 can limit the movement of the limiting rod 410 to the other end of the second limiting hole 322 (ie, the fourth end 322b shown in Figure 10) .

For example, please continue to refer to FIG. 16 and FIG. 17 . The above-mentioned limiting part 500 may be a limiting elastic piece 510 , and the limiting elastic piece 510 may be fixed on the inner wall of the second limiting hole 322 , so that the limiting elastic piece 510 The limit rod 410 forms a limit. When the terminal rotates between the unfolded state and the folded state, the user only needs to apply a certain external force, and the limit rod 410 squeezes the limit elastic piece 510, causing the limit elastic piece 510 to deform, that is, The limiting rod 410 can pass over the limiting elastic piece 510 and move toward the other end of the second limiting hole 322 .

It should be noted that the above-mentioned limiting elastic piece 510 can be disposed at a position close to the end of the second limiting hole 322 along its extension direction. For example, the limiting rod 410 is located at the second end 210b of the second limiting hole 322 . When the limiter elastic piece 510 is in contact with the side of the limiter rod 410 away from the second end 210b, the limiter rod 410 can be effectively limited.

In some embodiments, please continue to refer to FIGS. 16 and 17 . A mounting slot 323 may be provided on the inner wall of the second limiting hole 322 , and the limiting elastic piece 510 may be in contact with the mounting slot 323 , and the limiting elastic piece A partial area of 510 protrudes outside the installation groove 323 , that is, a partial area of the limiting elastic piece 510 is located in the second limiting hole 322 .

For example, the limiting elastic piece 510 may include a first elastic section 511 and a second elastic section 512. One end connected to the first elastic section 511 and the second elastic section 512 extends out of the installation groove 323. The first elastic section 511 and the second elastic section 512 are connected to each other. The free ends of the two elastic sections 512 are respectively in contact with the two opposite inner walls of the installation groove 323. For example, the free ends of the first elastic section 511 and the second elastic section 512 are respectively in contact with the second limit in the installation groove 323. The extending directions of the bit holes 322 are distributed on the two inner walls. In this way, when the limiting rod 410 squeezes the limiting elastic piece 510, the limiting elastic piece 510 can deform into the installation groove 323, so that the limiting rod 410 passes over the limiting elastic piece 510 and moves toward the second limiting hole 322. the other end of the movement.

Also, please refer to FIG. 18 , which is an enlarged view of the structure of region E in FIG. 17 . The inclination angle of the first elastic section 511 is smaller than the inclination angle of the second elastic section 512 , that is, the angle a formed between the first elastic section 511 and the bottom surface of the installation groove 323 is smaller than the angle a between the second elastic section 512 and the installation groove 323 . The angle b formed between the bottom surfaces of 323.

In this way, when the limiting rod 410 slides into the end of the second limiting hole 322, it can slide along the first elastic section 511. Since its inclination angle is small, the resistance exerted on the limiting rod 410 is small. So as to facilitate the limiting rod 410 to slide into the end of the second limiting hole 322 .

When the limiting rod 410 slides into the end of the second limiting hole 322, due to the larger inclination angle of the second elastic section 512, greater resistance can be exerted on the limiting rod 410 (compared to the first elastic section). (the resistance exerted by the section 511), thereby effectively limiting the positioning rod 410.

In addition, the above-mentioned limiting elastic piece can increase the starting force when the folding screen terminal 01 rotates between the unfolded state and the folded state, that is, the user needs to apply a large external force to enable the folding screen terminal 01 to rotate, that is, the above-mentioned limiting spring The rod 410 is separated from the second limiting hole 322 and the end of the first limiting hole 210, which is beneficial to optimizing the user's use feel. And when the folding screen terminal 01 is about to rotate to the unfolded state or the folded state, buffering can be achieved, that is, the limiting rod 410 abuts the first elastic section 511 and moves toward the end of the second limiting hole 322, thereby It can effectively protect the folding screen terminal 01.

On this basis, please refer to Figures 19 and 20. Figure 19 is an exploded view of another limiting spring piece 510 and the connection block 320 provided by the embodiment of the present application.

The limiting elastic piece 510 may also include a first extension section 513 connected to an end of the first elastic section 511 away from the second elastic section 512 , that is, provided at the free end of the first elastic section 511 . A first limiting groove 324 is defined in the inner wall of the installation groove 323 that is in contact with the first elastic section 511 , and the first extension section 513 is inserted into the first limiting groove 324 . Under this structure, by inserting the first extension section 513 into the first limiting groove 324, it is helpful to reduce the risk of the limiting elastic piece 510 popping out of the installation groove 323, which is beneficial to improving the reliability of the overall structure.

Moreover, the above-mentioned limiting elastic piece 510 may also include a second extension section 514. The second extension section 514 is provided at an end of the second elastic section 512 away from the first elastic section 511, that is, it is provided at the free end of the second extension section 514. A second limiting groove 325 is defined in the inner wall of the mounting groove 323 where the second elastic section 512 abuts, and the second extension section 514 is inserted into the first limiting groove 324 .
